煤制甲醇生产过程中杂醇油中水分含量分析方法准确性探讨

目前，在分析化验方面，水分测定的方法比较多，有相对密度法、卡尔费休法、露点法、色谱法等。针对神华宁煤甲醇厂煤制甲醇工艺生产过程中产生的杂醇油来说，使用哪种方法更能简单、准确的测定杂醇油中的水分含量是本文的重点。由于本文探讨的杂醇油中含水量较大（一般在30％左右），露点法和色谱法不适用，将直接进行相对密度法、卡尔费休法两种方法的探讨。

Canadian and American Reactions to Drug and Alcohol Testing Programs in the Workplace

We investigated U.S. and Canadian reactions to workplace drug and alcohol testing programs. Canadian truck drivers (n = 183) deemed drug and alcohol testing policies less fair, and were less accepting of these policies, than their American counterparts (n = 153). We also compared the perspectives of recipients versus third-party observers with regard to their reactions to a drug testing program. Unlike the pattern observed among American observers, the responses by Canadian observers were highly similar to those of the recipients. Canadian observers were more inclined to file a formal protest regarding the implementation of a drug and alcohol testing program than were U.S. observers. The results also showed that procedural and interactional justice principles contributed to the program's fairness, acceptance, and lower levels of protest intentions in both Canada and the United States. We propose that scholars and practitioners can gain a better understanding of multinational reactions to drug and alcohol testing by considering not only cultural but also historical, social, political, and other environmental factors that can shape reactions to personnel practices.

The Economics of Minimum Pricing for Alcohol

This article explores a wide range of issues that proponents of setting minimum prices for alcohol must resolve before they can safely claim their proposals improve public health and decrease public health care costs. Problems range from inability to know ‘correct’ prices and why tacking on pricing regulations to markets already taxed makes sense, to various unintended adverse consequences such as generating higher demand for illegal drugs and alcohol. It also remains unclear why advocates would not prefer to raise taxes since this is the typical method that economists propose to correct markets in which harm spills over to innocent parties.     

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.
