Does unemployment lead to a less healthy lifestyle?

In this article, we use 22 years of data from the German Socio-Economic Panel and information on plant closures to investigate the effects of unemployment on four indicators of unhealthy lifestyles: diet, alcohol consumption, smoking and (a lack of) physical activity. In contrast to much of the existing literature, which unlike our analysis is unable to assess causality, our results provide little evidence that unemployment gives rise to unhealthy lifestyles.     

A new approach to estimate concentrations of alcohol ethoxylate in rivers in Japan for screening-level risk assessment

Alcohol ethoxylate (AE) is a widely used household detergent that is ubiquitous in aquatic environments. To assess and manage the risk of AE, its environmental exposure concentrations must be evaluated in rivers nationwide; however, very few AE monitoring data are currently available. Furthermore, developing a rigorous exposure model that would cover rivers nationwide would require a great deal of time, human resources, and money. We developed a new approach to estimate AE concentrations in rivers throughout Japan for screening-level risk assessment. In this approach, five-day biochemical oxygen demand (BOD₅) data were used as a surrogate indicator of the AE concentration in river water. The Tama and Nikko Rivers were ranked according to their BOD₅ data, and the AE concentrations of the Nikko River were then estimated using the Standardized Hydrology-based Assessment tool for chemical Exposure Load (AIST-SHANEL) model. For each river, the concentrations of AE in its waters were projected based on that river’s reported BOD₅ values, its ranking, the approximation formula for AE and BOD₅, and estimated AE concentrations in water of the Nikko River from the model. The accuracy of the projected values was validated by comparing the projected AE concentrations in water from the Tama River with its monitoring data. There are various technical uncertainties associated with this approach; however, our results suggest that this new approach can be applied in screening-level exposure assessment of other chemical substances that have properties similar to AE.

滇池蓝藻的脱水及固化技术研究

通过向滇池蓝藻浆中分别加入生石灰、三氯化铁两种不同量的调理剂并进行抽滤脱水,脱水后采用天然高分子凝胶载体中的琼脂和有机合成高分子凝胶载体聚乙烯醇（PVA）作为固化剂对蓝藻进行固化处理。结果表明,三氯化铁的脱水性能较生石灰为好,其最佳投加量为4 g/50 mL,脱水率约为49.1%,脱水后蓝藻含水率为50.9%。经机械强度与耐热性测试后可知,聚乙烯醇固化效果较琼脂为好。     

Is what you see what you get? Investigating the relationship between social media content and counterproductive work behaviors,alcohol consumption,and episodic heavy drinking

Abstract

Employers are increasingly using social networking website (SNW) content to screen applicants for employment despite the absence of much empirical support for this practice. The purpose of this study was to examine the validity of using SNW content to predict employee behavior. Specifically, we investigated the relationship between SNW content and counterproductive work behaviors (CWB), occurrence of workplace accidents, alcohol consumption, and episodic heavy drinking. Participants (N = 146 MBA and upper level undergraduate business students) self-reported demographic information and information about workplace counterproductive behavior. Participants also provided access to their SNW profile, which the researchers subsequently accessed in order to assess potentially compromising content. Results indicate SNW profiles are not associated with CWB or involvement in workplace accidents, while SNW profiles containing alcohol and drug content are associated with alcohol consumption and episodic heavy drinking. Our study is among the first to examine the relationship between SNW profile information and CWBs of interest to HRM personnel and provides evidence that practitioners should exercise caution in drawing inferences about workplace behaviors based on SNW profile information.

甲基磺酸铜催化合成丙酸异戊酯的研究

研究了甲基磺酸铜催化丙酸和异戊醇的酯化反应,考察了催化剂用量、醇酸摩尔比、反应时间等因素对酯化率的影响;找到了较佳的反应条件:丙酸用量为0.15mol,醇酸摩尔比为1.2∶1,催化剂用量为0.25%(以丙酸的摩尔分数计),反应时间为3h,反应温度为85～90℃,环己烷用量为5mL(作为带水剂),在此条件下酯化率可达98.2%。反应结束后,通过简单的相分离即可达到产物与催化剂分离的目的。甲基磺酸铜重复使用8次后,其催化活性无明显下降,酯化率仍可达到93.1%。     

Advertising Bans, Monopoly, and Alcohol Demand: Testing for Substitution Effects using State Panel Data

Using a panel of 45 states for the period 1982–1997,this study analyzes the importance of severalrestrictive alcohol regulations, including advertising bans for billboards, bans of price advertising, state monopoly control of retail stores, and changes in the minimum legal drinking age. In contrast to previous research, the study allows for substitution among beverages as a response to a regulation that targets a specific beverage. A restrictive law that applies only to one beverage (or one form of advertising) can result in substitution toward other beverages (or non-banned media). Allowing for substitution means that the net effect on total alcohol consumption is uncertain, and must be determined empirically. The empirical results demonstrate that monopoly control of spirits reduces consumption of that beverage, and increases consumption of wine. The effect on beer is positive, but is not statistically significant. The net effect on total alcohol is significantly negative. Higher minimum legal drinking age laws have negative effects on beverage and total alcohol consumption. Bans of advertising do not reduce total alcohol consumption, which partly reflects substitution effects. The study thus demonstrates the possible unintended consequences of restrictive alcohol regulations.     

Evolving from a rum state: Australia's alcohol consumption

Europeans settlers in the Australian colonies had a reputation of being heavy drinkers. Rum dominated during the first few decades, followed by beer. It took until the 1970s before Australia's annual per capita consumption of wine exceeded 10 L, and even then, wine represented only one‐fifth of national alcohol consumption. But over the next two decades, per capita wine consumption nearly trebled and beer consumption shrunk – the opposite of what happened to global alcohol consumption shares. This paper draws on newly compiled data sets to (i) reveal that Australia was not much more alcoholic than Britain or southern Europe during the nineteenth century and (ii) help explain why it took so long for a consumer interest in wine to emerge in Australia.
