传播和媒介政策的出现 传播政策的出现始于追求国家利益与工商业企业利益之间的互动。政府和产业界通过特权、 法规和一些限制来追求共同利益。一般而言，政策指的是为实现某些目标而有意识制定的（公 共）方案，以及实现方案的方法和时间进度表。政府政策的特定内容反映了特定时期和地点政 府与产业界的交易以及权力与利益之间的平衡。从这个层面上说，虽然在20世纪，政府在形式 上变得更加民主，全球化的浪潮也愈演愈烈，政府和产业界的权力和利益之间的交易并没有多 大改变。然而即使是这样，媒介政策领域也发生了巨大的变化，这尤其反应在传播技术的演变 以及在“后工业”社会（或是更多地被称为“信息社会”）中传播重要性的提高。 虽然在几百年之前，国家就出于控制、财政和战略的目的，对交通和旅游进行干预和管制， 但如果说传播政策在自19世纪中期电话发明以来的一系列电子媒介出现以前就有了，那就错了。 在本文中，我们将传播政策阶段分为三个连续的阶段：（1)新兴传播业政策阶段，（2)公共 服务媒介政策阶段，和（3)新传播政策范式阶段。 传播政策的一般形态 媒介政策的主要元素撇开时间的变化与环境的差异不说，媒介政策和电信政策的主要元素包括：所追求的目标 或目的、界定目标的价值观念和标准、被政策规范的各种内容和传播服务；不同的传播渠道（主 要有印刷出版、有线电视、卫星电视、广播和电信）以及相应的政策措施和实施方法（主要包 含于法律、法规、自律和市场惯例）。 这个社会传播系统的普遍模型是从政策制定者的角度来描绘的，这些元素也是人为组合到 一起的，它并不能被普遍性地运用到所有的国家。另外这个模型也显得有点过时，因为各个国 家的社会体制和传播技术在一段时间内会发生重大的改变。为了阐明这个模型所表达的信息和 解释的方便，我们首先需要回顾一下政策制定的几个连续阶段，因为这些政策不仅在传播系统 上留下了历史痕迹，也影响着当今媒介政策所遇到的挑战。我们将首先讨论早期新兴的媒介和 传播政策阶段，这个阶段大约持续到二战。它不仅打开了改变世界的大门，而且与电视这个大 众媒介交相辉映地发展着。 新型传播政策： 政策制定者仍然面临许多困境和未解决的问题。对于一个国家来说，这些主要的问题有: 定义公共领域媒介的范围和目标；经济手段、法规和自律等政策方式的选择；为所有媒—— 欢迎下载 介领域寻找一致的原则和管制框架；如何定义和制定国家文化媒介政策；如何平衡传播自由以及社会需求。政策融合？在科技的影响下，通过选择相同的目标、原则和方式应用于统一的管制法规，媒介政策是 否回趋于融合？这样的观点已经获得了广泛的支持25并得以施行（如2002年英国传播法案），但 是这个问题并不能以简单地以‘‘是”或‘‘不是”来回答。虽然有理由淡化各种媒介之间的界限， 但对所有不同的媒介服务都使用同一种法规是没有必要的。欧洲现在的趋势是：尽管鼓励整体 性的政策思考，但也鼓励发展各国独立的国家法规权利机构来控制公共领域的媒介运作。当前 有足够的理由要求拥有一个连贯一致的政策体系(特别对待自由和多样性），但这并不意味着整 齐划一地处理所有媒介内容（广告、艺术、新闻、色情等等）。因为媒介内容与受众都存在着 明显的不同。所以，针对不同的用途使用不同的法规是可能的、甚至是必须的。公众的传播自 由还是非常重要的，也不应该让任何一个单一的机构对某种传播方式施加过多的压力，而且对 待不同的媒介也应该有特例和特殊的措施。另外，同样重要的一个方面是：为了保障传播所影 响的受众/公民的利益，我们也应该保留一块政治和社会文化价值观的领域。
新传播政策范式的核心原则 尽管还存在许多未知情况，我们仍有余地为兴起的新政策范式的核心原则提一些暂时的看 法。这些看法基于科技、政策和经济变化的趋势，以及现存公认的社会和政治限制。虽然公共 服务广播和普遍电信服务还不太可能从政治议事日程上消失，技术融合、传播市场自由化以及 信息和传播的迅速扩张要求我们对传播政策进行一次不同的概念化思考。如果对未来的估计是 正确的，以下三个概念将对新传播政策模型起核心作用：传播自由、使用权、和控制传播自由应该是未来所有传播政策的主要目标。传播自由可以被表述为负面和正面两个方 面。对前者来说，它指信息传播者独立于政府（没有审查），独立于经济或阻碍讯息自由交流 的其它力量（如，经济垄断和其他主导市场的力量），也包括社会和政治压力。从正面来说， 自由指人在社会中所能进行的自由活动，如参加政治议题的市民辩论，或表达艺术创意。这两 方面的规定都是政策目标所需要的。 传播法规与传播系统在许多不同的方面相关，即，传播业的市场结构，传播参与者的市场 行为或传播的内容。传播自由的负面主要与市场结构和市场行为相关，而正面自由主要与内容 和使用权相关，而后者也是我们关注的第二个核心原则。 —— 欢迎下载 对于互联网来说，三个核心原则中的两个对其政策制定有一定启发，即，自由和使用权。 互联网从一开始起就带有自由的属性，虽然如果没有政府最初的赞助，它也许不会发展至今。 由于多种原因，互联网的使用权已经被广泛的接纳为政策目标。尽管互联网政策的发展与前文 所提到的传播政策历史有些许相似，但未来的互联网政策依旧不可预测。互联网第一阶段的发 展以经济和商业利益为目标，而我们现在进入的是以控制公众利益为目标的第二阶段。目前还 有很多问题等待解决：对传播行为和内容（公众利益）采取什么样的控制手段？什么样的负责 限度是适合的？任何新出现的传播政策范式都必须对上述问题做出回应。

The emergence of communications and media policy The origins of communications policies lie in the interaction between the pursuit of national interests by states and the operations of commercial/ industrial enterprises. Both government and industry have sought mutual advantage by way of privileges, regulations and restrictions. Policies in general refer to conscious (public) projects for achieving some goal, together with the proposed means and time schedule for achieving them. The specific content of government policies reflects the deal made in the particular time and place and the balance of power and advantage between government and industry. At this level of generality, not a great deal has changed, despite the general transition during the 20th century to more democratic forms of government and increasing trends towards globalization. Even so, in the field of media policy there have been significant developments, especially reflecting the changing technologies of communication and the increased importance of communication in ‘postindustrial’ societies, which are more often known as ‘information societies’. Although for centuries there have been state interventions and regulations relating to transport and travel, for purposes of control, finance or for strategic reasons, it would be anachronistic to speak of communications policies before the series of electronic inventions beginning with the electric telegraph in the mid-19th century. In this article, we identify three main phases of communications policy-making. We may label these consecutive phases as (I) the phase of emerging communications industry policy, (II) the phase of public service media policy, and (III) the phase of a new communications policy paradigm.

According to the regression results,a strong tourism–agriculture nexus will not necessarily develop at a small scale of tourism demand.It appears that variables related to the entrepreneurial capital of the host economy are of notable explanatory significance.The human development index(HDI), which is used to measure a country's general level of development,is significantly and positively associated with tourism linkages.One plausible explanation for this is that international tourists,who often originate in high-income countries,may feel more comfortable and thus be inclined to consume more in a host country that has a life-style to which they can relate easily.Moreover,it is important to remember that the HDI also captures the relative achievements of countries in the level of health and education of the population.Therefore,a higher HDI reflects a healthier and more educated workforce,and thus,the quality of local entrepreneurship.Related to this point,it is important to underscore that the level of participation of women in the host economy also has a significantly positive effect on linkages.In sum, enhancing local entrepreneurial capital may expand the linkages between tourism and other sectors of the host country.Formal institutions and their regulatory control of the market,proxied by the size of the government and price controls,were not found to have significant effects on linkages formation.Despite the importance of democratic governance,this was not identified as a key determinant either.On the other hand,the significance of informal institutions accords with the clustering dynamics inherent in tourism,in which linkages are formed on the basis of self-enforcing“relations-based”governance.Also,informal structures cost less than formal,rules-driven institutional frameworks for entrepreneurship.Therefore,highly formalized regulations can deter the spontaneous and cost-driven coordination among potential local suppliers and the potential buyers of the tourism economy.One type of formal institutions that does matter is policing and vigilance.As would be expected,the results show that countries with higher incidence of violence or crime are significantly associated with lower levels of tourism linkages.Indeed, the coordination of providers in tourism clusters depends fundamentally on trust among local entrepreneurs and trust can hardly flourish in an environment characterized by social conflict.Equally important,the perception of violence on the part of tourists and hotels will dissuade tourists from venturing beyond the safe boundaries of the“enclave”hotel resort.Finally,hotel managers and other foreign investors in the tourism economy will be less inclined to maintain productive relations with the host economy in the absence of predictability and stability. Therefore,investments in institutions that maintain safety and a perception of safety,in the host economy appear critical for spawning coordination.While all country domains may be playing a role in fostering or hindering linkages, the business environment seems to exert an overriding influence on linkages.After controlling for a country's natural endowments,level of development,and institutional maturity,the business environment on its own explains almost20%of cross-country variations in linkages.In particular,the level of corporate taxes in the host economy is associated with the most significant adverse effect on the formation of linkages,in conformity with the lower-cost motivation underlying tourism-led linkage creation.Also,a widespread usage of internet is alsosignificantly associated with a positive effect in the ability of suppliers to orchestrate coordination in tourism linkages.Moreover,the results suggest that there could be a role for government in improving trade facilitation and reducing transportation costs.Also,maintaining an open trade regime seems to be critical for the emergence of linkages.This underscores the importance of not protecting inefficient economic activities and opening potential products for tourism demand to competition.Although trade barriers may indeed serve to prod investors in the tourism economy to procure domestic goods, they will also hinder the competitiveness of local producers.Shielded from imports, local producers will not have the incentives to meet the international quality standards of the products needed by the tourism economy.Yet,quality expectations, possibly more so than costs,will likely inform the procurement decisions of the tourism economy.Concerning the relative magnitude of the effects of the different domains on linkages,the business environment and trade regulations stand out.The independent contributions of these domains,that is their ability to explain variations in the dependent variable when no controls for other domains are applied,amount to53%and 43%,respectively.The level-of-development domain follows with25%explanatory power,while the domains covering institutions and endowments provide an independent contribution of23%each.The implications of the analysis should be considered in light of its limitations. Causal direction cannot be fully substantiated,because we use a cross-sectional approach due to data limitations.In the absence of time-series for the variables at hand,it is not possible to test for causation.While the explanatory variables concerning natural endowments are exogenous,some of the other explanatory variables could potentially be subject to reverse causality.That said,there do not seem to be a priori strong conceptual reasons that would lead us to believe that the degree of tourism linkages critically affects trade policy,the quality of institutions, and other variables of our model.Moreover,the risk of encountering problems of reverse causality is mitigated by the observation that several longitudinal studies have established a causal relationship that runs from higher levels of economic development Eugenio-Martin et al.(2008)or a better business environment(Barrowclough,2007and Selvanathan et al.,2009)to the development of the tourism sector,rather than the other way around.Finally,the construction of the dependent variable as a ratio of indirect to direct tourism expenditure makes the reverse causality hypothesis less compelling. While it might be expected that an expansion of the tourism sector that increases total revenues and employment opportunities might have an impact on the explanatory variables,it is less evident that a change in the composition of tourism revenues, as implied by a change in the LINK variable,would have such an effect.That said, the confidence in our findings would clearly be further enhanced,if supported by results from future studies based on longitudinal designs.The scientific environmental ethics plays a key role in the recognition of the human—environment interactions．Modern environmental ethics is the philosophical rethinking of modern human race environmental behavior．The development of environmental ethics theory as well as its application in reality．determines the viewpoints of environmental ethics．Sustainable development implies harmony on human-environment interactions and intergeneration responsibility，with emphasis on a harmonious relationship among population，resources，environment and development，so as to lay a sustainable and healthy foundation of resources and environment for future generations．The harmonious society construction in China that is raised by the Chinese central government should be covered by environmental ethics．The connotation of open environmental ethics includes a respect for nature．care for the individual human race．and respect for the development of future generations，which means giving consideration to natural values．individual and human race benefits and welfare across generations．The role of environmental ethics in regional development consists of cognition，criticism，education，inspiration，adjusting，legislation and promoting environmental regulations．The major problems in regional development are extensive resource exploration，fast population growth irrational,industrialstructure.Unfair welfare distribution and the twofold effects of science and technology development．The formulation of environmental ethics that aims at regional sustainable development，can not only harmonize the relationship of population，resource，environment and economic development，but also guide behavior selection，push social and political system transformation.strengthen the legal system，and raise environmental awareness of the public．Human races face severe global challenges in resources，environment，population and poverty．To solve these problems science and technology should be developed on one hand，and human-environment interactions should be adjusted on the other hand．Modem environmental ethics is the philosophical review on modem human race environmental behavior．Environmental ethics can be a view point as the moral perception of the relationship between humankind and nature in general．The keystone of sustainable development is on harmonious human．environment interactions．with an emphasis on sustainable environmental ethics．Environmental ethics and sustainable development are key issues in the study of man．1and system，as well as a precondition to regional development(Zheng，2005a)．Though there exists theoretical divergence in different environmental ideologies．some general understandings can also be obtained：human races are the only ethical agents on earth；the essence of the environmental crisis is a cultural and value crisis；future generations have the same right as current generations，especially on survival space；differences should be made between human race and other entities on earth，at the same time they are an undivided union；the capability of the earth is limited．Based on the above general understandings．it is possible to form a more open and sustainable environmental ethics．A more open and sustainable environmental ethics has some special connections．To respect and treat nature friendly means to acknowledge the value and right of nature，that is to say,minimum hurt criterion，basic benefit criterion and fair compensation criterion should be followed．To pay attention to both individuals and mankind should follow justice criterion，equity criterion and cooperation criterion．To have futuregeneration in mind Should follow responsibility criterion，saving criterion，and cautiousness criterion(Wang，2003；Wang，2004a)．The conclusion to be drawn from the above is to give attention to both human race and natural value．to both individual and mankind’s benefit。
外文文献综述电能质量监测（外文原文+中文翻译）
1 Power Quality MonitoringPatrick ColemanMany power quality problems are caused by inadequate wiring or improper grounding. These problems can be detected by simple examination of the wiring and grounding systems. Another large population of power quality problems can be solved by spotchecks of voltage, current, or harmonics using hand held meters. Some problems, however, are intermittent and require longer-term monitoring for solution.Long-term power quality monitoring is largely a problem of data management. If an RMS value of voltage and current is recorded each electrical cycle, for a three-phase system, about 6 gigabytes of data will be produced each day. Some equipment is disrupted by changes in the voltage waveshape that may not affect the rms value of the waveform. Recording the voltage and current waveforms will result in about 132 gigabytes of data per day. While modern data storage technologies may make it feasible to record every electrical cycle, the task of detecting power quality problems within this mass of data is daunting indeed.Most commercially available power quality monitoring equipment attempts to reduce the recorded data to manageable levels. Each manufacturer has a generally proprietary data reduction algorithm. It is critical that the user understand the algorithm used in order to properly interpret the results.1.1Selecting a Monitoring PointPower quality monitoring is usually done to either solve an existing power quality problem, or to determine the electrical environment prior to installing new sensitive equipment. For new equipment, it is easy to argue that the monitoring equipment should be installed at the point nearest the point of connection of the new equipment. For power quality problems affecting existing equipment, there is frequently pressure to determine it. the problem is being caused by some external source, i. e., the utility. This leads to the installation of monitoring equipment at the service point to try to detect the source of the problem. This is usually not the optimum location for monitoring equipment. Most studies suggest that 80% of power quality problems originate within the facility. A monitor installed on the equipment being affected will detect problemsoriginating within the facility, as well as problems originating on the utility. Each type of event has distinguishing characteristics to assist the engineer in correctly identifying the source of the disturbance.1.1.1 What to MonitorAt minimum, the input voltage to the affected equipment should be monitored. If the equipment is single phase, the monitored voltage should include at least the line-to~neutral voltage and the neutral to-ground voltages. If possible, the Iine_to_ground voltage should also be monitored. For three-phase equipment, the voltages may either be monitored line to neutral, or line to line. Line-to-neutral voltages are easier to understand, but most three-phase equipment operates on line-to-line voltages. Usually, it is preferable to monitor the voltage line to line for three-phase equipment.If the monitoring equipment has voltage thresholds which can be adjusted, the thresholds should be set to match the sensitive equipment voltage requirements. If the requirements are not known, a good starting point is usually the nominal equipment voltage plus or minus 10%.In most sensitive equipment, the connection to the source is a rectifier, and the critical voltages are DC. In some cases, it may be necessary to monitor the critical DC voltages. Some commercial power quality monitors are capable of monitoring AC and DC simultaneously, while others are AC only.It is frequently useful to monitor current as well as voltage. For example, if the problem is being caused by voltage sags, the reaction of the current during the sag can help determine the source of the sag. If the current doubles when the voltage sags 10%, then the cause of the sag is on the load side of the current monitor point. If the current increases or decreases 10 - 20% during a 10% voltage sag, then the cause of the sag is on the source side of the current monitoring point.Sensitive equipment can also be affected by other environmental factors such as temperature, humidity, static, harmonics, magnetic fields, radio frequency interference (RFl), and operator error or sabotage. Some commercial monitors can record some of these factors, but it may be necessary to install more than one monitor to cover every possible source of disturbance.It can also be useful to record power quantity data while searchingfor power quality problems. For example, the author found a shortcut to the source of a disturbance affecting a wide area by using the power quantity data. The recordings revealed an increase in demand of 2500 KW immediately after the disturbance. Asking a few questions quickly led to a nearby plant with a 2500 KW switched load that was found to be malfunctioning.1.2Selecting a MonitorCommercially available monitors fall into two basic categories: line disturbance analyzers and voltage recorders. The line between the categories is becoming blurred as new models are developed. Voltage recorders are primarily designed to record voltage and current strip chart data, but some models are able to capture waveforms under certain circumstances. Line disturbance analyzers are designed to capture voltage events that may affect sensitive equipment. Generally, line disturbance analyzers are not good voltage recorders, but newer models are better than previous designs at recording voltage strip charts.In order to select the best monitor for the job, it is necessary to have an idea of the type of disturbance to be recorded, and an idea of the operating characteristics of the available disturbance analyzers. For example, a common power quality problem is nuisance tripping of variable speed drives. Variable speed drives may trip due to the waveform disturbance created by power factor correction capacitor switching, or due to high or low steady state voltage, or, in some cases, due to excessive voltage imbalance. If the drive trips due to high voltage or waveform disturbances, the drive diagnostics will usually indicate an over voltage code as the cause of the trip. If the voltage is not balanced, the drive will draw significantly unbalanced currents. The current imbalance may reach a level that causes the drive to trip for input over current. Selecting a monitor for variable speed drive tripping can be a challenge. Most line disturbance analyzers can easily capture the waveshape disturbance of capacitor switching, but they are not good voltage recorders, and may not do a good job of reporting high steady state voltage. Many line disturbance analyzers cannot capture voltage unbalance at all, nor will they respond to current events unless there is a corresponding voltage event. Most voltage and current recorders can easily capture the high steady state voltage that leads to a drive trip, but they may notcapture the capacitor switching waveshape disturbance. Many voltage recorders can capture voltage imbalance, current imbalance, and some of them will trigger a capture of voltage and current during a current event, such as the drive tripping off.To select the best monitor for the job, it is necessary to understand the characteristics of the available monitors. The following sections will discuss the various types of data that may be needed for a power quality investigation, and the characteristics of some commercially available monitors.I. 3 VoltageThe most commonly recorded parameter in power quality investigations is the RMS voltage delivered to the equipment. Manufacturers of recording equipment use a variety of techniques to reduce the volume of the data recorded. The most common method of data reduction is to record Min/Max/Average data over some interval. Figure I. I shows a strip chart of rms voltages recorded on a eyeIe-by-cycle basis. Figure I. 2 shows a Min/Max/Average chart for the same time period. A common recording period is I week. Typical recorders will use a recording interval of 2 - 5 minutes. Each recording interval will produce three numbers: the rms voltage of the highest I cycle, the lowest I cycle, and the average of every cycle during the interval. This is a simple, easily understood recording method, and it is easily implemented by the manufacturer. There are several drawbacks to this method. If there are several events during a recording interval, only the event with the largest deviation is recorded. Unless the recorder records the event in some other manner, there is no time~stamp associated with the events, and no duration available. The most critical deficiency is the lack of a voltage profile during the event. The voltage profile provides significant clues to the source of the event. For example, if the event is a voltage sag, the minimum voltage may be the same for an event caused by a distant fault on the utility system, and for a nearby large motor start. For the distant fault, however, the voltage will sag nearly instantaneously, stay at a fairly constant level for 3-10 cycles, and almost instantly recover to full voltage, or possibly a slightly higher voltage it. the faulted section of the utility system is separated. For a nearby motor start, the voltage will drop nearly instantaneousIy,and almost immediately begin a gradual recovery over 30 - 180 cycles toa voltage somewhat lower than before. Figure 1.3 shows a cycle-by-cycle recording of a simulated adjacent feeder fault, followed by a simulation of a voltage sag caused by a large motor start. Figure I.4 shows a Min/Max/Average recording of the same two events. The events look quite similar when captured by the Min/Max/Average recorder, while the cycle-by-cycle recorder reveals the difference in the voltage recovery profile.FIGURE 1.1 RMS voltage strip chart, taken cycle by cycle.FIGURE I. 2 Min/Max/Average strip chart, showing the minimum single cycle voltage, the maximum single cycle voltage, and the average of every cycle in a recording interval. Compare to the Fig. I. I strip chart data.Some line disturbance analyzers allow the user to set thresholds for voltage events. If the voltage exceeds these thresholds, a short duration strip chart is captured showing the voltage profile during the event. This short duration strip chart is in addition to the long duration recordings, meaning that the engineer must look at several different charts to find the needed information.Some voltage recorders have user-programmable thresholds, and record deviations at a higher resolution than voltages that fall within the thresholds. These deviations are incorporated into the stripchart, so the user need only open the stripchart to determine, at a glance, if there are any significant events. If there are events to be examined, the engineer can immediately “zoom in” on the portion of the stripchart with the event.Some voltage recorders do not have user-settable thresholds, but rather choose to capture events based either on fixed default thresholds or on some type of significant change. For some users, fixed thresholds are an advantage, while others are uncomfortable with the lack of control over the meter function. In units with fixed thresholds, if the environment is normally somewhat disturbed, such as on a welder circuit at a motor control center, the meter memory may fill up with insignificant events and the monitor may not be able to record a significant event when it occurs. For this reason, monitors with fixed thresholds should not be used in electrically noisy environments.FIGURE I. 3 Cycle-by-cycle rms strip chart showing two voltage sags. The sag on the left is due to an adjacent feeder fault on the supply substation, and the sag on the right is due to a large motor start. Note the difference in the voltage profile during recoveryMln/Ave/Max Chartt SagFIGURE I. 4 Min/Max/Average strip chart of the same voltage sags as Fig. I. 3. Note that both sags look almost identical. Without the recovery detail found in Fig. I. 3, it is difficult to determine a cause for the voltage sagscapacitor energizationI. 3. I Voltage Waveform Disturbances.Some equipment can be disturbed by changes in the voltage waveform. These waveform changes may not significantly affect the rms voltage, yet may still cause equipment to malfunction. An rms-onIy recorder may not detect the cause of the malfunction. Most line disturbance analyzers have some mechanism to detect and record changes in voltage waveforms. Some machines compare portions of successive waveforms, and capture the waveform if there is a significant deviation in any portion of the waveform. Others capture waveforms if there is a significant change in the rms value of successive waveforms. Another method is to capture waveforms if there is a significant change in the voltage total harmonic distortion (THD) between successive cycles.The most common voltage waveform change that may cause equipment malfunction is the disturbance created by power factor correctioncapacitor switching. When capacitors are energized, a disturbance iscreated that lasts about I cycle, but does not result in a significant change in the rms voltage. Figure 1.5 shows a typical power factorFIGURE 1.6 RMS stripcharts of voltage and current during a large current increase due to a motor start downstream of the monitor point.1.4Current Waveshape DisturbancesVery few monitors are capable of capturing changes in current waveshape. It is usually not necessary to capture changes in current waveshape, but in some special cases this can be useful data. For example, inrush current waveforms can provide more useful information than inrush current rms data. Figure I. 7 shows a significant change in the current waveform when the current changes from zero to nearly 100 amps peak. The shape of the waveform, and the phase shift with respect to the voltage waveform, confirm that this current increase was due to an induction motor start.Figure 1.7 shows the first few cycles of the event shown in Fig.1.6.I.5HarmonicsHarmonic distortion is a growing area of concern. Many commercially available monitors are capable of capturing harmonic snapshots. Some monitors have the ability to capture harmonic strip chart data. In this area, it is critical that the monitor produce accurate data. Some commercially available monitors have deficiencies in measuring harmonics. Monitors generally capture a sample of the voltage and current waveforms, and perform a Fast Fourier Transform to produce a harmonic spectrum. According to the Nyquist Sampling Theorem, the input waveform must be sampled at least twice the highest frequency that is present in the waveform. Some manufacturers interpret this to mean the highest frequency of interest, and adjust their sample rates accordingly. If the input signal contains a frequency that is above the maximum frequency that can be correctly sampled, the high frequency signal may be u aliased, ” that is, it may be incorrectly identified as a lower frequency harmonic. This may lead the engineer to search for a solution to a harmonic problem that does not exist. The aliasing problem can be alleviated by sampling at higher sample rates, and by filtering out frequencies above the highest frequency of interest. The sample rate is usually found in the manufacturer’ s literature, but the presence of an antialiasing filter is not usually mentioned in the literature.I. 6 SummaryMost power quality problems can be solved with simple hand~tools and attention to detail. Some problems, however, are not so easily identified, and it may be necessary to monitor to correctly identify the problem. Successful monitoring involves several steps. First, determine if it is really necessary to monitor. Second, decide on a location for the monitor. Generally，the monitor should be installed close to the affected equipment. Third, decide what quantities need to be monitored, such as voltage, current, harmonics, and power data. Try to determine the types of events that can disturb the equipment, and select a meter that is capable of detecting those types of events. Fourth, decide on a monitoring period. Usually, a good first choice is at least one business cycle, or at least I day, and more commonly, I week. It may be necessary to monitor until the problem recurs. Some monitors can record indefinitely by discardingolder data to make space for new data. These monitors can be installed and left until the problem recurs. When the problem recurs, the monitoring should be stopped before the event data is discarded.After the monitoring period ends, the most difficult task begins — interpreting the data. Modern power quality monitors produce reams of data during a disturbance. Data interpretation is largely a matter of experience, and Ohm’ s law. There are many examples of disturbance data in books such as The BMI Handbook of Power Signatures, Second Edition, and the Dranetz Field Handbook for Power Quality Analysis.1量监测里•曼许多电能质量问题所造成的布线不足或不当的接地。

A high level design considering the soil-structure interaction, based on a qualified soil investigation is required for a safe and optimised design. Dueto the complexity of geotechnical constructions the safety assurance guaranteed by the 4-eye-principle is essential. The 4-eye-principle consists of an independent peer review by publicly certified experts combined with the observational method. The paper presents the fundamental aspects of safety assurance by the 4-eye-principle. The application is explained on several examples, as deep excavations, complex foundation systems for high-rise buildings and tunnel constructions in urban areas. The experiences made in the planning, design and construction phases are explained and for new inner urban projects recommendations are given.Key words: Natural Asset; Financial Value; Neural Network1.IntroductionA safety design and construction of challenging projects in urban areas is based on the following main aspects:Qualified experts for planning, design and construction;Interaction between architects, structural engineers and geotechnical engineers;Adequate soil investigation;Design of deep foundation systems using the FiniteElement-Method (FEM) in combination with enhanced in-situ load tests for calibrating the soil parameters used in the numerical simulations;Quality assurance by an independent peer review process and the observational method (4-eye-principle).These facts will be explained by large construction projects which are located in difficult soil and groundwater conditions.2.The 4-Eye-PrincipleThe basis for safety assurance is the 4-eye-principle. This 4-eye-principle is a process of an independent peer review as shown in Figure 1. It consists of 3 parts. The investor, the experts for planning and design and the construction company belong to the first division. Planning and design are done accordingto the requirements of the investor and all relevant documents to obtain the building permission are prepared. The building authorities are the second part and are responsible for the buildingpermission which is given to the investor. The thirddivision consists of the publicly certified experts.They are appointed by the building authorities but work as independent experts. They are responsible for the technical supervision of the planning, design and the construction.In order to achieve the license as a publicly certified expert for geotechnical engineering by the building authorities intensive studies of geotechnical engineering in university and large experiences in geotechnical engineering with special knowledge about the soil-structure interaction have to be proven.The independent peer review by publicly certified experts for geotechnical engineering makes sure that all information including the results of the soil investigation consisting of labor field tests and the boundary conditions defined for the geotechnical design are complete and correct.In the case of a defect or collapse the publicly certified expert for geotechnical engineering can be involved as an independent expert to find out the reasons for the defect or damage and to develop a concept for stabilization and reconstruction [1].For all difficult projects an independent peer review is essential for the successful realization of the project.3.Observational MethodThe observational method is practical to projects with difficult boundary conditions for verification of the design during the construction time and, if necessary, during service time. For example in the European Standard Eurocode 7 (EC 7) the effect and the boundary conditions of the observational method are defined.The application of the observational method is recommended for the following types of construction projects [2]:very complicated/complex projects;projects with a distinctive soil-structure-interaction,e.g. mixed shallow and deep foundations, retaining walls for deep excavations, Combined Pile-Raft Foundations (CPRFs);projects with a high and variable water pressure;complex interaction situations consisting of ground,excavation and neighbouring buildings and structures;projects with pore-water pressures reducing the stability;projects on slopes.The observational method is always a combination of the common geotechnical investigations before and during the construction phase together with the theoretical modeling and a plan of contingency actions(Figure 2). Only monitoring to ensure the stability and the service ability of the structure is not sufficient and,according to the standardization, not permitted for this purpose. Overall the observational method is an institutionalized controlling instrument to verify the soil and rock mechanical modeling [3,4].The identification of all potential failure mechanismsis essential for defining the measure concept. The concept has to be designed in that way that all these mechanisms can be observed. The measurements need to beof an adequate accuracy to allow the identification ocritical tendencies. The required accuracy as well as the boundary values need to be identified within the design phase of the observational method . Contingency actions needs to be planned in the design phase of the observational method and depend on the ductility of the systems.The observational method must not be seen as a potential alternative for a comprehensive soil investigation campaign. A comprehensive soil investigation campaignis in any way of essential importance. Additionally the observational method is a tool of quality assurance and allows the verification of the parameters and calculations applied in the design phase. The observational method helps to achieve an economic and save construction [5].4.In-Situ Load TestOn project and site related soil investigations with coredrillings and laboratory tests the soil parameters are determined. Laboratory tests are important and essential for the initial definition of soil mechanical properties of the soil layer, but usually not sufficient for an entire and realistic capture of the complex conditions, caused by theinteraction of subsoil and construction [6].In order to reliably determine the ultimate bearing capacity of piles, load tests need to be carried out [7]. Forpile load tests often very high counter weights or strong anchor systems are necessary. By using the Osterberg method high loads can be reached without install inganchors or counter weights. Hydraulic jacks induce the load in the pile using the pile itself partly as abutment.The results of the field tests allow a calibration of the numerical simulations.The principle scheme of pile load tests is shown in Figure 3.5.Examples for Engineering Practice5.1. Classic Pile Foundation for a High-Rise Building in Frankfurt Clay and LimestoneIn the downtown of Frankfurt am Main, Germany, on aconstruction site of 17,400 m2 the high-rise buildingproject “PalaisQuartier” has been realized (Figure 4). The construction was finished in 2010.The complex consists of several structures with a total of 180,000 m2 floor space, there of 60,000 m2 underground (Figure 5). The project includes the historic building “Thurn-und Taxis-Palais” whose facade has been preserved (Unit A). The office building (Unit B),which is the highest building of the project with a height of 136 m has 34 floors each with a floor space of 1340 m2. The hotel building (Unit C) has a height of 99 m with 24 upper floors. The retail area (Unit D)runs along the total length of the eastern part of the site and consists of eight upper floors with a total height of 43 m.The underground parking garage with five floors spans across the complete project area. With an 8 m high first sublevel, partially with mezzanine floor, and four more sub-levels the foundation depth results to 22 m below ground level. There by excavation bottom is at 80m above sea level (msl). A total of 302 foundation piles(diameter up to 1.86 m, length up to 27 m) reach down to depths of 53.2 m to 70.1 m. above sea level depending on the structural requirements.The pile head of the 543 retaining wall piles (diameter1.5 m, length up to 38 m)were located between 94.1 m and 99.6 m above sea level, the pile base was between 59.8 m and 73.4 m above sea level depending on the structural requirements. As shown in the sectional view(Figure 6), the upper part of the piles is in the Frankfurt Clay and the base of the piles is set in the rocky Frankfurt Limestone.Regarding the large number of piles and the high pile loads a pile load test has been carried out for optimization of the classic pile foundation. Osterberg-Cells(O-Cells) have been installed in two levels in order to assess the influence of pile shaft grouting on the limit skin friction of the piles in the Frankfurt Limestone(Figure 6). The test pile with a total length of 12.9 m and a diameter of 1.68 m consist of three segments and has been installed in the Frankfurt Limestone layer 31.7 m below ground level. The upper pile segment above the upper cell level and the middle pile segment between the two cell levels can be tested independently. In the first phase of the test the upper part was loaded by using the middle and the lower part as abutment. A limit of 24 MN could be reached (Figure 7). The upper segment was lifted about 1.5 cm, the settlement of the middle and lower part was 1.0 cm. The mobilized shaft friction was about 830 kN/m2.Subsequently the upper pile segment was uncoupled by discharging the upper cell level. In the second test phase the middle pile segment was loaded by using the lower segment as abutment. The limit load of the middle segment with shaft grouting was 27.5 MN (Figure 7).The skin friction was 1040 kN/m2, this means 24% higher than without shaft grouting. Based on the results of the pile load test using O-Cells the majority of the 290 foundation piles were made by applying shaft grouting. Due to pile load test the total length of was reduced significantly.5.2. CPRF for a High-Rise Building in Clay MarlIn the scope of the project Mirax Plaza in Kiev, Ukraine,2 high-rise buildings, each of them 192 m (46 storeys)high, a shopping and entertainment mall and an underground parking are under construction (Figure 8). The area of the project is about 294,000 m2 and cuts a 30 m high natural slope.The geotechnical investigations have been executed 70m deep. The soil conditions at the construction site are as follows: fill to a depth of 2 m to 3mquaternary silty sand and sandy silt with a thickness of 5 m to 10 m tertiary silt and sand (Charkow and Poltaw formation) with a thickness of 0 m to 24 m tertiary clayey silt and clay marl of the Kiev and But schak formation with a thickness of about 20 m tertiary fine sand of the But schak formation up to the investigation depthThe ground water level is in a depth of about 2 m below the ground surface. The soil conditions and a cross section of the project are shown in Figure 9.For verification of the shaft and base resistance of the deep foundation elements and for calibration of the numerical simulations pile load tests have been carried out on the construction yard. The piles had a diameter of 0.82 m and a length of about 10 m to 44 m. Using the results of the load tests the back analysis for verification of the FEM simulations was done. The soil properties in accordance with the results of the back analysis were partly 3 times higher than indicated in the geotechnical report. Figure 10 shows the results of the load test No. 2 and the numerical back analysis. Measurement and calculation show a good accordance.The obtained results of the pile load tests and of the executed back analysis were applied in 3-dimensionalFEM-simulations of the foundation for Tower A, taking advantage of the symmetry of the footprint of the building. The overall load of the Tower A is about 2200 MN and the area of the foundation about 2000 m2 (Figure11).The foundation design considers a CPRF with 64 barrettes with 33 m length and a cross section of 2.8 m × 0.8m. The raft of 3 m thickness is located in Kiev Clay Marl at about 10 m depth below the ground surface. The barrettes are penetrating the layer of Kiev Clay Marl reaching the Butschak Sands.The calculated loads on the barrettes were in the range of 22.1 MN to 44.5 MN. The load on the outer barrettes was about 41.2 MN to 44.5 MN which significantly exceeds the loads on the inner barrettes with the maximum value of 30.7 MN. This behavior is typical for a CPRF.The outer deep foundation elements take more loads because of their higher stiffness due to the higher volume of the activated soil. The CPRF coefficient is 0.88 =CPRF . Maximum settlements of about 12 cm werecalculated due to the settlement-relevant load of 85% of the total design load. The pressure under the foundation raft is calculated in the most areas not exceeding 200 kN/m2, at the raft edge the pressure reaches 400 kN/m2.The calculated base pressure of the outer barrettes has anaverage of 5100 kN/m2 and for inner barrettes an average of 4130 kN/m2. The mobilized shaft resistance increases with the depth reaching 180 kN/m2 for outer barrettes and 150 kN/m2 for inner barrettes.During the construction of Mirax Plaza the observational method according to EC 7 is applied. Especially the distribution of the loads between the barrettes and the raft is monitored. For this reason 3 earth pressure devices were installed under the raft and 2 barrettes (most loaded outer barrette and average loaded inner barrette) were instrumented over the length.In the scope of the project Mirax Plaza the new allowable shaft resistance and base resistance were defined for typical soil layers in Kiev. This unique experience will be used for the skyscrapers of new generation in Ukraine.The CPRF of the high-rise building project MiraxPlaza represents the first authorized CPRF in the Ukraine. Using the advanced optimization approaches and taking advantage of the positive effect of CPRF the number of barrettes could be reduced from 120 barrettes with 40 mlength to 64 barrettes with 33 m length. The foundation optimization leads to considerable decrease of the utilized resources (cement, aggregates, water, energy etc.)and cost savings of about 3.3 Million US$.译文:安全保证岩土公民发起挑战工程建设在城市地区摘要安全是最重要的方面在设计、施工和服务时间的任何结构,特别是对具有挑战性的项目,如高层建筑和隧道在城市地区。

Disclosing vulnerability information to a vendor should not be a painful or difficult process for the security researcher or the vendor. Ideally, we should all coexist and work together.In May of 2011, I reported several vulnerabilities affecting the S7-1200, a PLC designed and manufactured by Siemens. There was, for a time following my disclosure, a common misconception perpetrated by Siemens' marketing team, which informed Siemens customers that the attacks and vulnerabilities only affected the Simatic S7-1200.This is clearly untrue. The TCP replay and memory protection authentication bypass vulnerabilities are not specific to one type of PLC, as Siemens initially claimed.The issue is present in several different hardware platforms, as revealed by my own investigations and confirmed in the latest ICS-CERT alert. It was not until further investigation of other PLC models by ICS-CERT and myself was completed that Siemens felt obligated to make public certain information regarding additional affected products. Siemens also attempted to minimize the severity of the initially disclosed vulnerabilities by claiming that the S7-1200 was not used in nuclear power installations, and those higher-end PLCs that are used in such sensitive installations were not affected. That claim also turned out to be false.Myself and many control systems experts, such as Dale Peterson, Bob Radvanovsky, Jake Brodsky, Kevin Finisterre and Kevin Lackey, were immediately skeptical of these claims, and rightly so. Each of these individuals already knew the entire line of S7s were using the same protocols and standards, so it wasn’t long before I started receiving inquiries regarding what exactly was exploitable on the controllers. They all knew that if it were a protocolspecific implementation issue, the attacks would not only affect Siemens PLCs, but many other vendors as well. I imagine we will start seeing a significant number of disclosures relating to insecure use of protocols in the near future.Ralph Langner, Stuxnet expert, posted a comment on Digital Bond regarding the password authentication flaw.“The password mechanism on Siemens S7 controllers is so simple that option 1 can probably be ruled out. And the next bombs that are waiting to be dropped may be much more serious than what we have seen so far. Once that Dillon figures out how to delete OB1, which he might before dinner, and crafts this into a Metasploit module, he will have created a cyber assault weapon. Both Siemens and ICS-CERT know that this is technically possible and what the impact would be. While the vendor has no obligation to act on this, DHS certainly has.” –Ralph Langner.I believe that, especially when related to critical industrial control systems, it is preferable for an independent security researcher to discover product vulnerabilities and create public awareness by responsibly disclosing information to CERTs, rather than for our enemies to find the bugs and use them against us.I am not entirely convinced that a metasploit module should be described as acyber-assault weapon, but it does sound cool! The ruby modules were intended to serve as a proof of concept to assist the vendor in validating the bugs, and subsequently developing a patch. These “cyber-assault weapons” are also helpful to ICS-CERT, helping them validate the severity of the issue so they can keep the public informed. In addition, the modules are now available to the pen testing community to assist companies in testing their own infrastructure.The S7-300 and S7-400 are impacted by the same attacks as the S7-1200 with the exception of one denial of service attack against an integrated web server running on the S7-1200 (see ICS-ALERT-11-186-01.)The S7-300 and S7-400 are recognized by many as Siemens’ “bread and butter” products. It is apparent that they share the same key characteristics, including the use of ISO-TSAP and the same PROFINET communication protocol.One of the attacks that we will cover during the Black Hat presentation is the packet replay attack: SIEMENS-SSA-625789. Siemens refers to this issue as a “security gap”. However, if an attacker can capture a CPU STOP/START command or send a CPU READ/WRITE command to any PLC in the automation network, he can alter the operational logic on the controller or disable any process attached to the device, including, but not limited to, enabling hidden features on the PLC.Here is a quote from Siemens’ first advisory notice regarding some of the vulnerabilities and the replay attack scenario. They were already aware of the weak password authentication mechanism, and yet still recommended the feature as a viable solution to prevent remote exploitation of the controller.The Siemens advisory recommends:“It is not however, possible to replay the recorded data obtained from one controller to other controllers within the same plant or other plants as long as they are configured with unique passwords. The answer to this scenario is that a password protected S7-1200 will, in the future (with the firmware update), no longer respond to recorded frames transmitted to the controller at a later time.”--SIEMENS-SSA-625789.The Siemens marketing department has since changed its tone after I provided the exploit code (free of charge). This code will also be available in the Metasploit framework after ICS-CERT has released its advisories.Siemens CERT and a team of their engineers quickly responded to the replay attack scenario by claiming they had a mitigation effort in place to prevent unauthorized access to the PLC. After speaking with ICS-CERT and Siemens CERT, I quickly discovered the ease with which an attacker could circumvent the access control feature they had recommended to prevent unauthorized access to the controller.It is important to remember that this feature was not intended to prevent remote exploits or replay attacks against the device, it was designed to prevent other engineers or unauthorized third parties from re-programming or tampering with the programmable logic onthe PLC. Based on my observation of the packet replay scenario, it seemed logical that if one were to intercept the packets containing a password they could replay the same packets against any controller with the that password and gain access to the controller. It also became evident that if the controller had no password at all, any controller would accept any commands sent to and from any source, without validating any portion of the packets.Just as we enabled the password protection feature by sending a series of packets to the PLC containing a password, which in turn flips a bit in the PLC's memory to enable a protection flag, we could turn that flag off by sending the same packets back to the PLC.It was also clear to me that because everything sent to the controller by the engineering workstation is in plain text, it would be trivial for an attacker to decode the encoded password hash used to flip the memory protection built into the PLC. ICS-CERT verified and reported that the S7-200, S7-300, S7-400, and S7-1200 are all affected by the same protocol specific security vulnerabilities.Conclusion:We need secure protocols in ICS. The product vendors have the ability to make this a reality.The time has come for experts around the ICS community to come together and make the necessary changes to insure a safer environment for all those affected. That means everyone in the world who lives near or works in a factory or a power plant!When vendors misrepresent vulnerability information, their customers cannot properly assess the risk to their operations. Given Siemens ' public statements, it is hard to imagine the company taking the lead in ICS security. If trust is an important buying criteria, other vendors in this industry, such as GE and Rockwell, have an opportunity to set an example and gain market share in the future.供应商对漏洞信息的披露，不应该成为一个让安全研究人员或供应商痛苦的过程。

Enterprise risk management functionEnterprise faces all the risk of the capitalization of forms, is the embodiment of the operating risk of an enterprise.By definition, "enterprise risk management (ERM) is a process, is an entity's board of directors, management and other personnel, applied in a strategic stetting and the whole enterprise, designed to identify potential events, and risk management, the entity within the risk preference to provide reasonable assurance that to achieve the goals. Entity" (COSO enterprise risk management-integrated framework (2004))Although the CEO job and senior management assessment and management company's exposure to risk, the audit committee (or in some cases, appointed a commission to) was charged with the responsibility of risk committee to discuss specific policies, establish and provide supervision and management of the process enterprise risk management process. In today's height in the form of currency in the economy and society, the enterprise in the environment of market economy organization with production and operating activities and bear all kinds of risk, its occurrence, development and risks are concentrated reflection is the reality of the enterprise or the underlying economic interests losses, all kinds of operating loss can also in a certain way into economic loss. From this perspective, the enterprise risk of the size and the losses have direct and clear representation in enterprise financial revenues and expenditures of the change, eventually ?Enterprise financial activities in the process, because every uncertainty factors, the actual financial status and financial situation is expected to possible deviation, cause loss and produce the financial risk. Strengthen enterprise's scientific management especially financial management is standardization of construction, the sustainable and healthy development of way.As mentioned above, the risk management is a process, including the documented risk assessment and management oversight process.Risk management procedures, including the documented risk assessment and establish management supervision process, is unique, each organization, is dedicated to ensure that the risk management process development bank in all bank address operation and business units. From this perspective, the enterprise shall establish a monetary fund business post responsibility system, clearly related department and post responsibility and authority, ensure the incompatibility of monetary fund business from each position, and restriction and supervision. Enterprise risk of the size and the losses have direct and clear representation in enterprise financial revenues and expenditures of the change, and finally the performance for the enterprise financial benefits reduced.The risk management of the whole process:The audit committee of the board of directors is responsible for the independent and objective supervision function, accounting and financial reporting and internal control audit function of the company. The enterprise risk assessment, risk management and audit plan (the basis of risk appraisal) defined procedures and related enterprise risk management audit function of the company.Integrated architecture is taking risk auditing function of the concept of risk, how to access these risk management, and the role of how to use the audit function. Enterprise risk management concepts, including:1.recognition, the source, the distribution and measure risk and responsibility2.risk strategy design3.implementation strategies4.review and monitoring an on-going basismunicate resultsIn order to facilitate the audit committee of the auditing function should be responsible management policy of a risk evaluation audit committee, all the operating areas (business process and unit) company for identify those could be dangerous area of the company. Risk can be identified and defined risk assessment of these units:1. credit,2. interest rates,3. market,4. liquidity,5. operation,6. supervision and management,7. law (hard),8. strategy and capital,9. reputationThe purpose of the risk assessment is to find out the inherent risks and internal control for each business process, thus leading to the development of the unit, the risk audit plans to allocate resources to verify and operation control system based on internal risk and business processes or unit.1. methodology of the risk assessment is to review and appraisal risk.2. The amount of risk ? (inherent risk),3. quality risk management (control risk),4. total risk assessmentBased on this analysis will determine the level as risk is low, medium or high, and the direction of risk-increasing, stable, reduce, in all the company business unit (defined as audit the universe).Risk assessment should also give effect (12 months) short term and long term (more than 12 months) business units expect the company's annual budget process links and long-term strategic plan.Risk assessment and corresponding audit plan should be reviewed and approved the audit committee and the board of the directors. Risk assessment should be updated need minimal, but the foundation of every year, in order to ensure the proper resources to audit function, make sure the identified risk is by audit plan. From the perspective of economics, the modern the financial risk of the enterprise is a microscopic economic risk, is the enterprise faces all the risk of the capitalization of forms, is the embodiment of the operating risk of an enterprise. Enterprise even reasonable arrange capital, avoid the mistakes bring capital scheduling financial risk, liquidity is the measure of a enterprise pay due debt of the scale of the ability. To maintain a high level of liquidity that enterprise control financial risk, and reduce the important guarantee of the financial pressure. Enterprise assets more easily get ?Risk management is throughout the company through the exercise of a matrix for the definition of risk management measures therapy. Risk management plan is to identify risks including every component as mentioned by using internal development risk managementprocesses, management team monitoring and management procedures, the board of directors and the committee report related board and supervision.. Enterprise adventure there will always be risks, the enterprise can't continue to the profit, regardless of the outcome, wantonly investment debt, increase financial burden. Management of risk management system is mainly produced imperfect system, caused the financial management activities in the corner and blind area. The implement of system is inadequate, reduce the management work of the actual effect; The supervision measures do not reach the designated position, weakened financial regulatory control; The management means not updating, restricted the management efficiency. These eventually led to the generation of accounting information, the transmission, the whole process of examination management does not arrive, the cause of the accounting information authenticity, integrity could not be guaranteed, information to deliver timely affected, affect decision-making more scientific and reasonable, increases the risk of decision-making errors. Which leads to the enterprise of the financial risk of intensified. In addition, in the management personnel, as we all know, the formation of any risks with people about, risk prevention, the human element is very important. If can not solve the problem of management, again good ?Enterprise in financing process, must influence financing activities of all kinds of factors are analyzed, and follow the certain financing principle to improve financing efficiency and reduce funding risk and financing cost. General enterprise's main purpose is to raise money for their own normal production and operation and the development, is in order to expand the scale of production and operation, to improve the economic benefit. Enterprise adventure there will always be risks, the enterprise can't continue to the profit, regardless of the outcome, wantonly investment debt, increase financial burden. Enterprise financing should master certain principles. Enterprise financing should master certain principles. Such as the appropriate scale, reasonable structure, cost saving and financing according to law. Summarize the risk evaluation matrix each company's major business unit/process will be developed. The following definitions are, each risk type identification in constant risk evaluation matrix, followed by the company's internal processes or risk management scheme to identify types of risk, address. In market economic waves, in a highly competitive environments, the benefits and risks always, the greater the risk, the greater the profits, high risk will bring high return. If the enterprise does not dare to risk, it may lose a lot of opportunity, because the risk of existence, also can give enterprise to bring the opportunity to get high profits. But at the same time, the enterprise must learn to control risk, increase to resist the ability of the risk.Also discusses and analyses the bank's risk profile determining internal control process can provide enterprises and institutions of risk assessment. Since then, the company according to the characteristics of the enterprise and capital requirements were number of possible investment company. In the screening, the risk of enterprise to consider the factors including: enterprise required the size of the investment; The geographical location of the enterprise; Enterprise's stage of development and development; Sales of enterprise profit and; The management of the enterprise range, etc. Usually, in the process, lawyers and accountants to play a large role.When measuring the risk in the business unit or a given process, consider the risk inherent risk (quantity) a given area. For example, some regions, such as the loan portfolios of quality,Shanghai/AML compliance and information system because of its natural or current foreign influence has a higher level of inherent risk, usually in financial institutions consistent regardless of size and complexity. Quality risk management provides a measure of control and process means to reduce risk in a particular risk category. In addition, in the management personnel, as we all know, the formation of any risks with people about, risk prevention, the human element is very important. If can not solve the problem of management, again good internal control system is of no help, a moral risk of out of control, again good regulations also resist the deliberately illegal enterprise. Under the guideline, the board of directors of the company and the audit committee, enterprise management should use risk management plan extensive, involves a series of partition scheme, unity of the assessment of the way the audit committee and senior management, supervision and the board of directors.。

外文文献A marketer’s guide to behavioral economicsApirl.2010 • Ned Welch • McKinsey QuarterlyMarketers have been applying behavioral economics-often unknowingly for years. A more systematic approach can unlock significant value.Long before behavioral eco nomics had a name, marketers were using it. “Three for the price of two” offers and extended-payment layaway plans became widespread because they worked—not because marketers had run scientific studies showing that people prefer a supposedly free incentive to an equivalent price discount or that people often behave irrationally when thinking about future consequences. Yet despite marketing’s inadvertent leadership in using principles of behavioral economics, few companies use them in a systematic way. In this article, we highlight four practical techniques that should be part of every marketer’s tool kit.1. Make a product’s cost less painfulIn almost every purchasing decision, consumers have the option to do nothing: they can always save their money for an other day. That’s why the marketer’s task is not just to beat competitors but also to persuade shoppers to part with their money in the first place. According to economic principle, the pain of payment should be identical for every dollar we spend. In marketing practice, however, many factors influence the way consumers value a dollar and how much pain they feel upon spending it.Retailers know that allowing consumers to delay payment can dramatically increase their willingness to buy. One reason delayed payments work is perfectly logical: the time value of money makes future payments less costly than immediate ones. But there is a second, less rational basis for this phenomenon. Payments, like all losses, are viscerally unpleasant. But emotions experienced in the present—now—are especially important. Even small delays in payment can soften the immediate sting of parting with your money and remove an important barrier to purchase.Another way to minimize the pain of payment is to understand the ways “mental a ccounting” affects decision making. Consumers use different mental accounts for money they obtain from different sources rather than treating every dollar they own equally, as economists believe they do, or should. Commonly observed mental accounts include windfall gains, pocket money, income, and savings. Windfall gains and pocket money are usually the easiest for consumers to spend. Income is less easy to relinquish, and savings the most difficult of all.Technology creates new frontiers for harnessing mental accounting to benefit both consumers and marketers. A credit card marketer, for instance, could offer a Web-based or mobile-device application that gives consumers real-time feedback on spending against predefined budget and revenue categories—green, say, for below budget, red for above budget, and so on. The budget-conscious consumer is likely to find value in such accounts (although they are not strictly rational) and to concentrate spending on a card that makes use of them. This would not only incre ase the issuer’s interchange fees andfinancing income but also improve the issuer’s view of its customers’ overall financial situation. Finally, of course, such an application would make a genuine contribution to these consumers’ desire to live within the ir means.2. Harness the power of a default optionThe evidence is overwhelming that presenting one option as a default increases the chance it will be chosen. Defaults—what you get if you don’t actively make a choice—work partly by instilling a perception of ownership before any purchase takes place, because the pleasure we derive from gains is less intense than the pain from equivalent losses. When we’re “given” something by default, it becomes more valued than it would have been otherwise—and we are more loath to part with it.Savvy marketers can harness these principles. An Italian telecom company, for example, increased the acceptance rate of an offer made to customers when they called to cancel their service. Originally, a script informed them that they would receive 100 free calls if they kept their plan. The script was reworded to say, “We have already credited your account with 100 calls—how could you use those?” Many customers did not want to give up free talk time they felt they already owned.Defaults work best when decision makers are too indifferent, confused, or conflicted to consider their options. That principle is particularly relevant in a world that’s increasingly awash with choices—a default eliminates the need to make a decision. The default, however, must also be a good choice for most people. Attempting to mislead customers will ultimately backfire by breeding distrust.3. Don’t overwhelm consumers with choiceWhen a default option isn’t possible, marketers must be wary of generating “ch oice overload,” which makes consumers less likely to purchase. In a classic field experiment, some grocery store shoppers were offered the chance to taste a selection of 24 jams, while others were offered only 6. The greater variety drew more shoppers to sample the jams, but few made a purchase. By contrast, although fewer consumers stopped to taste the 6 jams on offer, sales from this group were more than five times higher.Large in-store assortments work against marketers in at least two ways. First, these choices make consumers work harder to find their preferred option, a potential barrier to purchase. Second, large assortments increase the likelihood that each choice will become imbued with a “negative halo”—a heightened awareness that every option requires you to forgo desirable features available in some other product. Reducing the number of options makes people likelier not only to reach a decision but also to feel more satisfied with their choice.4. Position your preferred option carefullyEconomists assume that everything has a price: your willingness to pay may be higher than mine, but each of us has a maximum price we’d be willing to pay. How marketers position a product, though, can change the equation. Consider the experience of the jewelry sto re owner whose consignment of turquoise jewelry wasn’t selling. Displaying it more prominently didn’t achieve anything, nor did increased efforts by her sales staff. Exasperated, she gave her sales manager instructions to mark the lot down “x½” and departed on a buying trip. On her return, she found that the manager misread the note and had mistakenly doubled the price of the items—and sold the lot.2 In this case,shoppers almost certainly didn’t base their purchases on an absolute maximum price. Instead, t hey made inferences from the price about the jewelry’s quality, which generated a context-specific willingness to pay.The power of this kind of relative positioning explains why marketers sometimes benefit from offering a few clearly inferior options. Eve n if they don’t sell, they may increase sales of slightly better products the store really wants to move. Similarly, many restaurants find that the second-most-expensive bottle of wine is very popular—and so is the second-cheapest. Customers who buy the former feel they are getting something special but not going over the top. Those who buy the latter feel they are getting a bargain but not being cheap. Sony found the same thing with headphones: consumers buy them at a given price if there is a more expensive option—but not if they are the most expensive option on offer.Another way to position choices relates not to the products a company offers but to the way it displays them. Our research suggests, for instance, that ice cream shoppers in grocery stores look at the brand first, flavor second, and price last. Organizing supermarket aisles according to way consumers prefer to buy specific products makes customers both happier and less likely to base their purchase decisions on price—allowing retailers to sell higher-priced, higher-margin products. (This explains why aisles are rarely organized by price.) For thermostats, by contrast, people generally start with price, then function, and finally brand. The merchandise layout should therefore be quite different.Marketers have long been aware that irrationality helps shape consumer behavior. Behavioral economics can make that irrationality more predictable. Understanding exactly how small changes to the details of an offer can influence the way people react to it is crucial to unlocking significant value—often at very low cost.不可或缺的营销四技巧多年来，营销商一直在运用行为经济学，但往往是不自觉地运用。
员工激励理论外文文献及翻译.
员工激励理论外文文献及翻译员工激励理论外文文献及翻译One-to-one-management companiesare run -- in a timely inversion of John Adams's ideal -- as organizations of men (and women), not of laws. Nonetheless, a few laws, or at least cultural traits, appear to govern many such organizations. Together those traits create an environment where employees' needs are known, sometimes anticipated, and served, justas customers' needs are known, sometimes anticipated, and served in CRM-focused organizations. What follows is a look at the rules by which one-to-one-management companies operate[2].3.2 It's All in the DetailHow do you build morale and a sense of corporate responsibility? In surprisingly small ways. Standing in the kitchen at Eze Castle Software, CEO Sean McLaughlin watches as one of his programmers sets milk and cookies on a table. It's 2:30 on a Wednesday afternoon. "Hang on, Parvathy," McLaughlin says to the employee as he opens the refrigerator door and pulls out an apple pie. "Put this out, too." When Parvathy is done in the kitchen, she flips some switches, andthe lights flicker all over the fifth floor. Almost instantly, programmers leave their cubicles and make a beeline for thekitchen.Then Parvathy jogs up a staircase and flashes the lights on the sixth floor. Account managers, salespeople, and assorted techies come downstairs and join their colleagues in the kitchen. When they arrive, McLaughlin is at the center of the steadily building crowd, dishing out the pie. Around him conversations spring up between colleagues who work in different departments. The topics range from work to social life to politics. Ten minutes later the lights flash again and it's back to work for the 90 employees in the Boston office of Eze.What's so remarkable about the staff of a developer of securities-trading software with $13 million in revenues taking daily milk-and-cookies breaks? Not much -- until you consider that the practice is part of a cultural shift engineered by the CEO, a shift that has profoundly changed the way he and his employees relate toone another. Perhaps more significant, the changes have affected how employees deal with the myriad little details that keep the six-year-old company grounded.原文请找腾讯3249114六-维^论,文.网Eze's transformation began last year, when McLaughlin realized to his chagrin that his once small and collegial company had -- because of accelerated growth -- begun acting like a large corporation. His employees no longer knew one another, and he himself was increasingly vague about who some of the new faces were. "In the early days I could get to know everyone," saysMcLaughlin.However, the CEO was most annoyed by the fact that his employees -- both old and new -- were beginning to behave with large-company sloppiness rather than with start-up frugality. "Back when we were small, if someone sent a FedEx, we all knew how much that was costing the company," McLaughlin says. He recalls noticing that things were changing when one employee approved paying a contractor $100 a month to water the company's five plants. Then there were rising charges from the company's Internet service provider because of excessive traffic on the corporate T1 line. The cause? Employees were downloading MP3 files to listen to music during the workday. It frustrated McLaughlin that employees weren't taking responsibilityfor their actions and for the ways in which those actions affected the company's bottom line[2].But last summer two things happened that spurred McLaughlin to make some changes.First, the Boston office lost both of its administrative assistants. One assistant quit and the other left a few weeks later. The two had stocked the supply room, sorted the mail, and welcomed visitors. The dual departures wreaked havoc. "The kitchen was out of milk, we didn't have any pens in the supply cabinet, the reception area looked like crap," McLaughlin says.Then came the World Trade Center attacks. Though McLaughlin had long been brooding on how to reverse Eze's fat-cat habits, he had yet to act. He says that 9-11, and the "what are my priorities" thinking it engendered, "created an environment where it was easy for me to initiate a change."The change he had in mind was inspired by a visit to his daughter's kindergarten class. There he saw how the teacher divided the cleanup tasks among the children by posting a rotating "chore wheel." McLaughlin thought the wheel was just the thing to clean up the mess and teach his employees a little corporate responsibility. But he also wanted to institute something that would help improve camaraderie. That's where another kindergarten institution, the milk-and-cookies breaks, came in. "I wanted to build relationships among the employees, to make them feel more company morale," he says.上一页[1] [2] [3] [4] [5] [6] [7] [8] [9] 下一页。

经营分析与估值克雷沙·G.帕利普保罗·M.希利摘自书籍“Business Analysis and Valuation”第五版第一章节1.简介本章的目的是勾勒出一个全面的财务报表分析框架。
因为财务报表提供给公共企业经济活动最广泛使用的数据，投资者和其他利益相关者依靠财务报告评估计划企业和管理绩效率。
各种各样的问题可以通过财务状况及经营分析解决，如下面的示例所示：一位证券分析师可能会对问：“我的公司有多好？这家公司是否符合我的期望？如果没有，为什么不呢？鉴于我对公司当前和未来业绩的评估，该公司的股票价值是多少？”一位信贷员可能需要问：“这家公司贷款给这家公司有什么贷款？公司管理其流动性如何？公司的经营风险是什么？公司的融资和股利政策所产生的附加风险是什么？“一位管理顾问可能会问：“公司经营的行业结构是什么？该策略通过在工业各个企业追求的是什么？不同企业在行业中的相对表现是什么？”公司经理可能会问：“我的公司是正确的估值的投资者吗？是我们在通信程序中有足够的投资者来促进这一过程？”财务报表分析是一项有价值的活动，当管理者在一个公司的战略和各种体制因素完成后，他们不可能完全披露这些信息。
在这一设置中，外部分析师试图通过分析财务报表数据来创建“中端信息”，从而获得有价值的关于该公司目前业绩和未来前景的展望。
了解财务报表分析所做的贡献，这是很重要的理解在资本市场的运作，财务报告的作用，形成财务报表制度的力量。
因此，我们首先简要说明这些力量，然后我们讨论的步骤，分析师必须执行，以提取信息的财务报表，并提供有价值的预测。
2.从经营活动到财务报表企业管理者负责从公司的环境中获取物理和财务资源，并利用它们为公司的投资者创造价值。
当公司在资本成本的超额投资时，就创造了价值。
管理者制定经营战略，实现这一目标，并通过业务活动实施。
企业的经营活动受其经济环境和经营战略的影响。
经济环境包括企业的产业、投入和产出的市场，以及公司经营的规章制度。
