Organizational Compatibility and Workplace Drug Testing: Modeling the Adoption of Innovative Social Control Practices

Few researchers have examined organizational variation in the adoption of workplace drug testing, but innovation theory suggests that adoption is more likely when it is compatible with an organization's values, previously introduced ideas, and needs. Using data from the 1997 National Employee Survey, this research models the effects of organizational compatibility, industry, and establishment size on the adoption of drug testing. The data reveal that compatibility, as measured by an organization's rules orientation, presence of an employee assistance program, and mechanization, is associated with the adoption of drug testing. As predicted, the adoption of drug testing varies across industries and by establishment size.     

The EU‐Turkey‐'deal': Legal Challenges and Pitfalls

The EU‐Turkey “deal”, based on the Joint Action Plan (JAP) between the European Union (EU) and Turkey, raises fundamental questions on the range of European asylum law as well as on the scope of the safe third country concept, which has turned out to serve as a political master key to “solve” the problems of the so‐called “refugee crisis” in Europe. This article discusses the legal possibilities of the application of the concept as well as its limitations regarding the human rights orientation of European and international law, focusing on the evolvement and legal implementation of the “Merkel Plan”. The legal analysis also focusses on recent ideas to make new “deals” with third states such as Libya. It concludes with a critical but differentiated(?) acclaim of the controversial externalizing policy approach.     

New bounds for locally irregular chromatic index of bipartite and subcubic graphs

A graph is locally irregular if the neighbors of every vertex v have degrees distinct from the degree of v. A locally irregular edge-coloring of a graph G is an (improper) edge-coloring such that the graph induced on the edges of any color class is locally irregular. It is conjectured that three colors suffice for a locally irregular edge-coloring. In the paper, we develop a method using which we prove four colors are enough for a locally irregular edge-coloring of any subcubic graph admiting such a coloring. We believe that our method can be further extended to prove the tight bound of three colors for such graphs. Furthermore, using a combination of existing results, we present an improvement of the bounds for bipartite graphs and general graphs, setting the best upper bounds to 7 and 220, respectively.     

Large-scale commonness is the best predictor of bird species presence in European cities

Urban Ecosystems - Urban bird communities are homogenized across large spatial scales, suggesting that the urban environment acts as an environmental filter. We hypothesize that large scale...     

Recovery and detachment between shifts, and fatigue during a twelve-hour shift

The study investigated the role of recovery and detachment in the break period between two shifts for fatigue in the current shift. A time-based paper-and-pencil diary study was carried out observing sixty-four railway controllers over ten consecutive working shifts. The results demonstrated that fatigue in the current shift was not only affected by recovery and psychological detachment during break phases before a shift, but also by fatigue at shift onset and perceived workload during the shift.     

Household Saving Behavior and the Influence of Family-Owned Business

This study focused on the lifecycle income objective of business-owning (farm and nonfarm) households. We hypothesized that the complex relationship between household and business management decisions had the potential to challenge predictions from standard household savings theory. Specifically, we tested for differences in saving behavior of these entrepreneurial households relative to the average US household. A limited dependent variable model was performed, keying in on the saving behavior and ability of household respondents in the Survey of Consumer Finances for 2007. The estimation results indicated that, along with standard demographic influences of savings models, households owning a farm or nonfarm business had a significantly higher likelihood of maintaining private saving in a given year. Our results highlight the necessity for future research on household saving behavior to account for the differing objectives and choice sets faced by households that own businesses when conducting analyses of household saving.

Understanding the Relationship Between Egalitarianism and Affective Bias: Avenues to Reducing Prejudice Among Adolescents

In an era during which affirmative action in education is in jeopardy, it is important to understand how the ideologies of high-status ethnic group members maintain (or reduce) social inequality. We examine the extent to which the relationship between egalitarianism and prejudice among European American and Asian American adolescents can be explained by outgroup orientation (i.e., how much one values interacting with members of other ethnic groups) and strength of identification with one's ethnic group. Using structural equation modeling, we tested whether these two variables mediate the relationship between egalitarianism and intergroup prejudice. Results revealed that outgroup orientation was a mediator, but ethnic identity was not. Implications for mutual acculturation theory, prejudice-reduction programs, and affirmative action in education are discussed.     

Strengthening the science–policy interface in the climate migration field

The question of how climatic changes and hazards affect human mobility has increasingly gained prominence in public debates over the past decade. Despite improvements in the scientific understanding of the subject and advancements in policy, major gaps remain in addressing the humanitarian and socio-economic challenges related to climate migration. In this perspectives article, we argue for a holistic approach and a closer integration of science and policy involving diverse stakeholders in the process of knowledge generation and implementation. We identify five key challenges characteristic for improving the science–policy interface: (i) conflictual political contexts and the securitization of human migration, (ii) simplistic narratives and framing of the subject, (iii) the uneven production and dissemination of knowledge, (iv) limited data and analytical capacities and (v) a selective topical and methodological focus. To address these diverse challenges, there is a need for more bridging initiatives at the science–policy interface that integrate diverse disciplines, approaches and stakeholders. A closer engagement of researchers and policymakers in the form of multi-stakeholder exchanges, capacity-building activities, co-development and co-implementation processes and integrative scientific assessments can help bridge the gap to support the inclusive generation of knowledge and the development of comprehensive policies.
