亚洲发展中国家的能源效率与节能：过去的经验,未来趋势及投资需求

本文分析了几个亚洲发展中国家或地区(中国、印度、印度尼西亚、韩国、菲律宾、中国台湾省以及泰国)1980～1994年期间能源效率与节能情况的变化,重点分析了它们所取得的成就和未来的节能潜力。中国是终端能源密度下降最为迅速的国家,但仍是终端能源密度最高的国家。台湾省的终端能源密度也呈持续的下降趋势,这归因于其采取了适当的能源定价政策,即在稳步转变经济结构的同时,取消了对所有能源的价格补贴。亚洲发展中国家未来节能战略总体上是要继续实行和强化现行的节能措施,并进一步寻求实施需求端管理。需求端管理计划的制度化和节能辅助基金的建立是亚洲发展中国家节能潜力在未来得以实现的强有力的推动力。     

Does reputation of sponsors matter in IPO? Evidence from Hong Kong

Contrary to other markets where underwriters perform a combined role of underwriting and sponsoring in an Initial Public Offering (IPO), IPO issuers in Hong Kong must appoint at least one sponsor in addition to the underwriters. The splitting of the single role of underwriters into two separate ones offers an ideal setting to disentangle the effects of the two roles and to examine which of the two roles—sponsor or underwriter—is more important in explaining IPO underpricing and initial volatility in the Hong Kong equity market. Interestingly, our findings provide supportive evidence that the sponsor reputation does matter in an IPO and it is even more significant than the underwriter reputation in explaining the IPO underpricing phenomenon. Given the recent high-tech fervor, our research goes deeper to examine specifically the role of sponsors on high-tech firms, with results indicating that the reliance on sponsors is higher for traditional issuers than for technology firms. We further discover that sponsors and underwriters are playing substitution roles rather than complementary roles. In order to examine the regulatory policy impact, our research also compares the role of IPO sponsors before and after the launch of the new sponsor regulatory regime in 2013. The empirical findings lend support to our argument that after the launch of the new regulations, public awareness of sponsors is raised, respect towards more reputable sponsor increases, and thus, the role of sponsors becomes more important than before.     

带偏射补偿机制的Birkhoff-von-Neumann交换机方案及其性能分析

Birkhoff-von-Neumann（BvN）交换机具有较低的执行复杂度和较高的吞吐量,但无法在业务突发的环境下提供性能保证。为此,提出一种带偏射的BvN（D-BvN）交换机制来增强交换机性能。D-BvN交换机通过平均业务矩阵的BvN分解,为每个虚电路（VC）提供均值带宽保证,同时通过偏射来处理业务突发。其主要思想是利用处于空闲状态的VC的闲置容量处理处于溢出状态的VC的溢出业务。具体地,偏射机制利用空闲VC的闲置容量完成两件事情：一是把溢出业务偏射到其他VC,二是给偏射业务提供到达目的端口的带宽。分析和仿真结果表明,所提方法不仅可以获得接近100%的输入负载吞吐量,而且具有较低的包乱序概率和较小的业务包延时。     

The legal framework and initiatives for promoting safety in the United Arab Emirates

Injury is a leading cause of morbidity and mortality in the United Arab Emirates (UAE). The UAE is a rapidly developing country with fast economic growth, demographical and environmental changes that are associated with new hazards emerging at a similar pace. The UAE as a federal entity has federal and local systems responsible for safety policy, regulations and enforcement. To set priorities for safety promotion and injury prevention, it is necessary to have data on the most frequent external causes of injury and the main individual, equipment and environmental risk factors that contribute to injury. However good quality data for injury prevention are scarce. The aim of this paper is to describe the scale of injury as a public health problem in the UAE, and the development of safety policies, regulations and promotion efforts with special emphasis on traffic, occupational and child safety.     

Last Call: decreasing drunk driving among 21-34-year-old bar patrons

Any effort to decrease the toll of drunk driving must include efforts directed at people who drink in bars, particularly young adults who use motor vehicles after drinking. We designed a multifaceted social marketing campaign, Last Call, to increase the use of designated drivers and safe rides homes among 21-34-year olds. There were three components to the intervention: (1) use of taxi stands to promote taxi use; (2) point-of-sale information to patrons at partner bars and (3) a mass media campaign to support the designated driver/safe ride home message. Among the heaviest drinkers, the programme significantly increased the use of designated drivers and increased the use of taxis by 63%.     

Toddler drowning prevention: teaching parents about water safety in conjunction with their child's in-water lessons

The primary objective of the study was to develop a parent education programme that addressed parental misconceptions of toddler water safety previously identified by the authors. Parents (n = 106) of 2-4-year-old toddlers enrolled in swim school lessons completed a self-directed questionnaire before and after a 10-week poolside water safety programme. Differences in pre- and post-programme knowledge and beliefs were measured by frequency and chi-square tested to identify significant changes in parental comprehension of toddler water safety after the programme. Statistically significant improvements in parental understanding were evident after the programme. More parents were aware of the family or friend's swimming pool as the primary site of toddler drowning (59% vs. 78%). More parents agreed that their toddler required more, not less, adult supervision after swimming lessons (85% vs. 97%) and more disagreed that swimming lessons were the best way to prevent toddler drowning (65% vs. 74%). Parental understanding of child cardiopulmonary resuscitation (CPR), however, did not improve after the programme. This study suggests that toddler lessons in swim schools provide a valuable opportunity to address parental misconceptions about toddler water safety. Further research is required to determine how parents whose toddlers do not attend swimming lessons might similarly benefit from such a programme.     

Another look at the relationship between socioeconomic factors and the black-white health benefit inequality

This paper illustrates the black-white disparity in health benefit coverage and the socioeconomic variables-unemployment, income, and education. The health benefit disparity is strongly related to the disparity in underlying socioeconomic variables. Moreover, the time-series examination reveals that the change in white workers' health insurance coverage is largely determined by its year-to-year persistence and the labor market tightness (or the business cycle), while that of black workers is largely determined by the change in their earnings with a slight persistence. The effect of the change in annual earnings seems to dominate the effect of the labor market condition (unemployment rate) and other variables. Finally, although marginally significant, an increase in the attainment of higher education (college) has a positive effect on the black-white health benefit disparity.     

为了您的标识着想，请注重工程学 泥土状况报告可有助于决定标识的设计要求和地基深度

Managing retention

To build this process it is necessary to consult customers for preferences, build familiarity and knowledge to build a relationship and conduct business in a customized fashion. The process takes every opportunity to build customer satisfaction with each customer contact. It is an important process to have, since customers today are more demanding, sophisticated, educated and comfortable speaking to the company as an equal (Belk, 2003). Customers have more customized expectations so they want to be reached as individuals (Raymond and Tanner, 1994). Also, a disproportionate search for new business is costly. The cost to cultivate new customers is more than maintaining existing customers (Cathcart, 1990). Other reasons that customer retention is necessary is because many unhappy customers will never buy again from a company that dissatisfied them and they will communicate their displeasure to other people. These dissatisfied customers may not even convey their displeasure but without saying anything just stop doing business with that company, which may keep them unaware for some time that there is any problem (Cathcart, 1990).     

Older adult pedestrian injuries in the United States: causes and contributing circumstances

As the US population ages, more older adults will face transportation and mobility challenges. This study examines the characteristics and contributing circumstances of nonfatal older adult pedestrian injuries. Data were obtained from the National Electronic Injury Surveillance System-All Injury Programme (NEISS-AIP) for the years 2001 through 2006. Cases included persons aged 65 years and older who were nonfatally injured on a public roadway. The results indicated that on average, an estimated 52,482 older adults were treated in emergency departments each year for nonfatal pedestrian injuries. Falling and being hit by a motor vehicle were the leading mechanisms of injury, resulting in 77.5% and 15.0% of older adult pedestrian injuries, respectively. More than 9000 older pedestrian fall-related injuries each year involved a kerb. It is concluded that the growth in the older adult population could add to the overall burden of these nonfatal pedestrian injuries. Making transportation and mobility improvements, including environmental modifications, is important for preventing these injuries.
