Charleston's newfound “entertainment zone”: should we be concerned?

This CIT Research Letter addresses issues related to the night-time economy and the rapid proliferation of bars along a section of a tourism oriented city's main street. Merely 10 years ago, locals did not frequent the area, it was of no interest to tourists, and it was regarded as a neighbourhood where one would not want to walk, especially at night. However, with the area's transformation to the nightlife centre of the city, issues have arisen that are of concern to city government officials. This paper considers these concerns.

地震资料叠前深度偏移处理质量控制

叠前深度偏移处理目前已广泛应用于地震勘探资料处理中,被认为是解决复杂地质构造正确成像困难问题较好方法,但其处理成果同时又受多种因素影响,需要在资料处理过程中加以控制。通过分析这些影响因素,提出消除或削减这些影响的方法,达到正确还原地层构造形态的目的。     

What is driving increases in dietary quality in the United States?

Over 1994–2010, adult dietary quality in the United States increased by 10 percent. We find a shift in consumption between at-home and away-from-home food played a relatively minor role as compared to changes in demographics and educational attainment. The two largest contributors we identify include an increased usage of nutritional information and a shift away from relying heavily on price, taste, storability and ease of preparation when shopping for food. Our findings suggest nutrition policy discussions could focus on further shifting attitudes/preferences towards healthier diets while allowing consumers to better extract nutrition information when making food choices.     

Vertical differentiation via multi-tier geographical indications and the consumer perception of quality: The case of Chianti wines

We derive and estimate a model of demand for Geographical Indications allowing for subjective and heterogeneous quality perceptions, and study vertical differentiation based on multi-tier quality labels within the context of the strategy adopted by the Chianti Consortium. Quality perceptions and wine choices are elicited in an online experiment where the number of quality tiers is augmented incrementally in a between-subject design. The empirical model includes subjective quality perceptions as an (endogenous) explanatory variable, and unexplained heterogeneity in WTP for quality as a random parameter. We find that quality perceptions are endogenous to the labeling regime, and adding a high-quality label (Chianti Classico Gran Selezione) decreases the perceived quality of all other Chianti wines, but not the competitor wines. However, the market shared lost to perception restructuring is small compared to the benefits of increased vertical differentiation.     

滚压抽油杆常见质量问题及原因分析

抽油杆滚压加工作为一种修复抽油杆的新工艺具有良好的经济效益,但是由于其自身的工艺设计和质量控制的特点,在使用过程中出现了一些早期失效问题。通过对这些失效的抽油杆的宏观形貌分析、材料的化学成分及金相组织分析,认为滚压抽油杆的杆体直径、表面质量、直线度不符合标准,镦锻前加热设备设计不合理是造成滚压抽油杆早期失效的主要原因。最后提出了确保滚压抽油杆符合标准、提高其质量的方法。
