有源测试与无源测试“仅”用手提检测器进行测试，不利于安装吗？

目前,评测超5类结构化布线系统的标准,都记录在2000年1月发行的TIA/EIA(电信工业协会/电子工业联合会)568A-5当中。6类系统的标准应在一年左右得到认可。 近来,各公司都开始提出,要想真正得到一个确保网络最大效率的结构化布线系统,唯一的方法就是选择那些在有源信道中经过独立测试的产品,

Negligent hiring: Reducing the risk

In recent years, the responsibility of employers to hire people who are not dangerous or violent has been heightened by the tort, negligent hiring. The courts have ruled that certain employers owe a special duty to employees and third parties (e.g., customers or clients) to protect them from the harmful or criminal acts of other employees. This article contrasts negligent hiring to respondent superior and negligent entrustment, describes the components of negligent hiring, and reviews important legal cases. The article also discusses how employers can minimize the risk of negligent hiring through prudent human resource practices.     

The Delphi method, impeachment and terrorism: Accuracies of short-range forecasts for volatile world events

Two experiments examined the effects of iterated polling and feedback on prediction accuracy for volatile world events using the Delphi paradigm. In both experiments, participants predicted rapidly changing geopolitical events. The first experiment occurred during the litigation surrounding the Clinton/Lewinsky affair in 1998. Results indicated that feedback improved individual and group accuracy for predictions of whether an event would occur. These types of predictions derived from group consensus were approximately 90% accurate, which was significantly higher than the average individual participant's accuracy. Neither polling nor feedback had much effect on time course predictions. The second experiment occurred during the American military action against the Taliban regime in Afghanistan in 2001. In Experiment 2, participants were polled three times to determine if increasing the number of iterated polls would improve Delphi accuracy. The results showed that accuracy improved from the first to the second poll but not from the second to the third. The groups predicted whether these scenarios would occur with approximately 75% accuracy, which was significantly higher than the accuracy of any individual participant. Once again, the Delphi procedure did not enhance time course predictions in Experiment 2.     

Crafting a public image: An empirical study of the ethics of ghostwriting

Ghostwriting is viewed by some as a necessary element for crafting an effective public image. Defenders of ghostwriting see no ethical dilemma in the practice because the audience knows the speechgiver is not necessarily the speechwriter. Alernatively, those regarding ghostwriting as unethical view the practice as deceitful. This group argues that the audience does not recognize the employment of a speechwriter and thus a speechgiver relies on the words of another to fortify personal ethos. This article examines several positions regarding the ethics of ghostwriting and discusses an empirical study testing three major positions found in ghostwriting literature. Findings from the study indicate that respondents do recognize the use of speechwriters by certain individuals in certain circumstances.Linda A.

Obeying the rules: Accounting for regulatory compliance costs in the United Kingdom

The U.K. Government has embarked on a deregulatory programme aimed at ‘liberating’ business from, inter alia, onerous regulatory compliance costs. In doing so it has developed and utilized an accounting-based technique known as Compliance Cost Assessment (CCA). This paper describes and analyses this technique, and demonstrates that CCA has been used as a perceived rational tool to counter regulatory growth and to privilege certain interests in society.     

Empowering the new traveller: storytelling as a co-creative behaviour in tourism

The work proposes a theoretical and empirical model that investigates how storytelling is a powerful co-creative behaviour in tourism. The contribution takes a step forward from the classical theories on co-creation and develops the case where consumers act almost independently from traditional brands. The empirical study adopts an interpretive approach to analyse online travel reviews. Data are interpreted through Yi and Gong's model on consumer value co-creation behaviour [(2013). Customer value co-creation behavior: Scale development and validation. Journal of Business Research, 66, 127], the Phase dynamics theory of travel epiphany behaviour [Woodside, A. G., & Megehee, C. M. (2010). Advancing consumer behaviour theory in tourism via visual narrative art. International Journal of Tourism Research, 12(5), 418–431], and the Archetype theory [Woodside, A. G., Sood, S., & Miller, K. E. (2008). When consumers and brands talk: Storytelling theory and research. Psychology & Marketing, 25(2), 97–145]. The study indicates that storytelling behaviours in value co-creation activate a ‘customer delight' response, which is an affect-based construct.     

Empowering Justice: An Intersectional Feminist Perspective on Restorative Justice in the Sex Trade

Restorative justice might seem like a benign alternative to prison, but it is full of pitfalls, particularly when it is still enmeshed in the criminal justice system. Nowhere is this more true than with sex workers, who are either punished for their work or morally castigated for it. The criminal justice system's interventions into the sex trade, even when using programs based on restorative justice, fails to address the harms and conflicts women experience in the sex trade and street economy. A major reason restorative programs fail to serve women in the sex trade is because it remains tethered to the criminal justice system, which carries traditional punitive consequences. When women entrenched in these conflicts are given the space, support, and freedom, they are able to develop relationships and resolutions that better exemplify restorative values. This paper explores the limitations of the current relationship between restorative justice and the criminal justice system and then highlights how the relationships and resistance strategies of the Young Women's Empowerment Project demonstrated restorative justice praxis in the sex trade.     

Some Variants of Constrained Estimation in Finite Population Sampling

This is a review article that unifies several important examples using constrained optimisation techniques. The basic tools are three simple mathematical optimisation results subject to certain constraints. Applications include calibration, benchmarking in small area estimation and imputation. A final illustration is constrained optimisation under a general divergence loss.
