An improved cluster two-stage randomized response model

In this paper, Abdelfatah and Mazloum's (2015) two-stage randomized response model is extended to unequal probability sampling and stratified unequal probability sampling, both with and without replacement. The extended models result in more efficient estimators than Lee et al.'s (2014) estimators of the proportion of the population having a sensitive attribute.     

Improved randomized response in additive scrambling models

Randomized response models deal with stigmatizing variables appearing in health surveys. Additive and subtractive scrambling in split sample and double response yield unbiased mean and sensitivity estimators of high precision. The split sample method is protective of privacy. The double response method is as protective only conditionally. To achieve the maximum efficiency, the scrambling variables must be similar to each other and the probability of obtaining a true response must be as large as possible. The randomized response procedures yield more efficient estimates of the average total number of classes missed by university students.     

A content analysis of BP's press releases dealing with crisis

This study aims to analyze what kinds of frames have been used in British Petroleum's (BP's) press releases, which dealt with the Gulf oil spill crisis that occurred in April 2010. A content analysis was conducted to explore the different frames used by BP in its press releases to deal with the crisis. The main and sub themes are also analyzed through a content analysis of press releases. This study attempts to examine BP's crisis communication strategy through press release usage by closely analyzing the frames and themes that were used. This study found that BP attempted to update the public on what the company was doing to resolve the oil spill crisis, and that they made every effort to manage the crisis by using the company's official update frame. In addition, by using the social responsibility frame, BP aimed to show the public that they had intentions of taking responsibility for the oil spill. Finally, BP used a minimal number of defensive frames as a way of showing the public that they did not want to flee from the responsibility of the oil spill crisis.     

后金融危机时期完善公允价值计量的探索

在2008年的金融风暴中,公允价值计量虽然暴露出其固有缺陷,但目前仍不失为一种面对市场的、动态反映产权价值运动的最佳计量模式。在后金融危机时期,我们需要通过建立健全市场机制、降低公允价值计量的实际操作难度、完善估值技术等手段进一步修改与完善公允价值计量模式,助推经济复苏与调整。     

Job quality,industrial relations and the crisis in Europe

This paper reports results from recent Eurofound research on the impact of the crisis on industrial relations and working conditions in Europe, based on the output of Eurofound's European Working Conditions Observatory and European Industrial Relations Observatory and data from the European Working Conditions Survey. Overall, the crisis – even if it is sometimes difficult to separate the effect of the crisis from megatrends in working conditions and industrial relations – seems to have had an impact on both domains. With reference to industrial relations, the impact of the crisis has influenced actors, processes, and outcomes. Regarding working conditions, the results appear to be in line with the literature on the topic, which relates the crisis to an increase in job insecurity, a decrease in work intensity, in working hours, and in anti-social working time arrangements, and a general improvement in terms of health risks and related outcomes.     

Evaluation of Inhaled Versus Deposited Dose Using the Exponential Dose‐Response Model for Inhalational Anthrax in Nonhuman Primate,Rabbit, and Guinea Pig

The application of the exponential model is extended by the inclusion of new nonhuman primate (NHP), rabbit, and guinea pig dose‐lethality data for inhalation anthrax. Because deposition is a critical step in the initiation of inhalation anthrax, inhaled doses may not provide the most accurate cross‐species comparison. For this reason, species‐specific deposition factors were derived to translate inhaled dose to deposited dose. Four NHP, three rabbit, and two guinea pig data sets were utilized. Results from species‐specific pooling analysis suggested all four NHP data sets could be pooled into a single NHP data set, which was also true for the rabbit and guinea pig data sets. The three species‐specific pooled data sets could not be combined into a single generic mammalian data set. For inhaled dose, NHPs were the most sensitive (relative lowest LD₅₀) species and rabbits the least. Improved inhaled LD₅₀s proposed for use in risk assessment are 50,600, 102,600, and 70,800 inhaled spores for NHP, rabbit, and guinea pig, respectively. Lung deposition factors were estimated for each species using published deposition data from Bacillus spore exposures, particle deposition studies, and computer modeling. Deposition was estimated at 22%, 9%, and 30% of the inhaled dose for NHP, rabbit, and guinea pig, respectively. When the inhaled dose was adjusted to reflect deposited dose, the rabbit animal model appears the most sensitive with the guinea pig the least sensitive species.     

Changes in the labour market and health inequalities during the years of the recent economic downturn in Italy

There is widespread concern that episodes of unemployment and unstable working conditions adversely affect health. We add to the debate by focusing on the relationship between work trajectory and the self-reported health of Italian men and women during the present economic downturn. Relying on Italian data in the EU-SILC project (from 2007 to 2010), our sample includes all individuals aged 30 to 60 in 2010, and uses multivariate binomial regression models for preliminary analyses and the Structural Equations modelling (SEM) to observe the cumulative effects of health status according to different job trajectories. Our main findings show similar pictures for men and women. Individuals who are unemployed, ejected or in precarious occupational positions have a higher risk of worsening their health status during these years.     

Determinants of public attitude towards a social enterprise crisis in the digital era: Lessons learnt from THINX

This study examines how the perceived locus of crisis cause, controllability, and adherence to social mission are associated with public attitude in the context of a social enterprise crisis and evaluates the differences between these variables under episodic and thematic frames of online articles. Using the crisis case of THINX in 2017 as a case study, a quantitative content analysis was performed on a sample of 503 comments under online articles. Hierarchical regression revealed that the locus of crisis cause and adherence to social mission were associated with public attitude, whereas controllability was not associated with public attitude when adherence to social mission was accounted for. Significant differences were found in the locus of crisis cause, controllability, adherence to social mission, and public attitude between episodic and thematic frames. This study provided a basis for the theoretical development of crisis communication in a social enterprise and the corresponding role for public relations.     

公共危机管理中的公民参与:价值、困境与路径选择——基于社会资本范式的研究

公民参与是公共危机管理的一个重要问题。社会资本理论是分析社会发展的一种重要理论,对公民参与具有较强的解释力。本文梳理了公民参与、公共危机管理和社会资本的相关概念和内涵,以社会资本为中介和基础分析了公共危机管理中公民参与的价值;在社会资本缺失和负外部性下讨论了公民参与公共危机管理的困境;并通过社会资本的投资和自我完善分析了公民参与公共危机管理的路径选择。     

国际金融危机背景下大学生实践能力培养策略研究

国际金融危机给高校大学生就业带来了困难的同时,也给大学生实践能力的培养提出了挑战。提高大学生的社会实践能力,尽快适应社会发展需求,需要政府、高校、用人单位、大学生＂四位一体＂的联动,即发挥政府政策导向作用,发挥高校资源优势作用,建立与用人单位合作培养机制,树立大学生自我培养意识。
