Non‐dominated Time‐Window Policies in City Distribution

Urban freight contributes significantly to pollution, noise disturbance, traffic congestion, and safety problems in city centers. In many cities, local governments have introduced policy measures, in particular time‐access restrictions, to alleviate these problems. However, setting time windows is very challenging due to the conflicting interests and objectives of the stakeholders involved. In this article, we examine whether it is possible to develop time‐window policies that enhance environmental sustainability and distribution efficiencies, while meeting the objectives of the municipalities. We develop a framework for balancing retailer (costs), municipality (satisfaction), and environmental (emissions) objectives, using data envelopment analysis, under different urban time‐window policies. The approach is illustrated by a case study of three Dutch retail organizations, with a large number of stores affected by such time windows. On the basis of an evaluation of 99 different time‐window policies, our results show that harmonizing time windows between neighboring cities leads to the best overall performance. The currently used time‐window policy appears to perform reasonably well, but can be improved on all dimensions . However, harmonizing time‐window policies may be difficult to realize in practice.     

Attitudes Toward Women in Health Care Organizations: A Turkish Case Study

Abstract

The aim of this article is to examine the health care employees’ attitudes toward women in health care organizations in Turkey. It was measured using a 25-item scale by Spence, Helmreich, and Stapp (1973 Spence, J. T., Helmreich, R., & Stapp, J. (1973). A short version of the Attitudes toward Women Scale (AWS). Bulletin of the Psychonomic Society, 2(4), 219–220. doi:10.3758/BF03329252[Crossref] , [Google Scholar]). The study was conducted on 541 employees: 279 males and 262 females. Structural equation model (SEM) was applied to analyze the relationship between gender, marital status, and income and attitudes toward woman. The result of this analysis showed that the relations between gender, marital status, and income and attitudes toward woman were statistically significant. All three hypotheses were statistically supported. This result indicated that employees’ marital status and (monthly) income significantly predicted their scores of attitudes toward woman in a positive direction. Besides, employees’ gender significantly predicted their scores of attitudes toward woman in an inverse direction. Future research can focus on investigating the effects of the attitudes toward women on other elements (e.g., performance, motivation, job satisfaction) or a wider sample to reach more generalized results.     

The International from the perspectives of Gezi Protestors

Gezi Protests that started in Istanbul and spilled over to other cities in the Spring of 2013 has been regarded as an important episode of Turkish politics in the 21^st century. Although it happened in congruous with protests movements in different localities in the world as well as significant transformations in Turkey's foreign policy, the question of the influence of the international in these protests has been largely unexplored. This paper presents the empirical findings of a fieldwork on Gezi Protests, asking the following questions: What was the perception of the actors on the neighbouring as well as geographically distant uprisings that were congruous in time? How do they perceive the roles of domestic and international politics in shaping the agenda of their movements?     

Preventing and Diagnosing Colorectal Cancer with a Limited Colonoscopy Resource

This paper explores how the capacity of colonoscopy services should be allocated for screening and diagnosis of colorectal cancer to improve health outcomes. Both of these services are important since screening prevents cancer by removing polyps, while diagnosis is required to start treatment for cancer. This paper first presents a basic compartmental model to illustrate the trade‐off between these two analytically. Further, a more realistic population dynamics model with resource constraints is introduced for colorectal cancer screening and analyzed numerically. The best resource allocation decisions are investigated with the objectives of minimizing mortality or incidence rates. We provide a sensitivity analysis with respect to policy and disease‐related parameters. We conclude that to minimize mortality, the capacity should be rationed to ensure that the wait for diagnosis is at reasonable levels. When the relevant performance measure is the incidence rate, screening is allocated more capacity compared to the case with mortality rate measure. We also show that benefits from increasing compliance to screening programs can only be realized if there is sufficient service capacity.     

The student movement in Turkey: a case study of the relationship between (re)politicization and democratization

One particularly striking aspect of the global waves of social movements is the increasing politicization of youth, including students. Taking this as its starting point, this article discusses what the politicization of youth could mean for democracy and democratization in Turkey. This is important because, especially since 2011, Turkish politics has been dominated by debates concerning authoritarianization. Focusing on the largest student organization in Turkey, the Student Collectives (SC), this article shows that the relationship between politicization and democratization is more complicated than at first sight. Some aspects of the student movement in Turkey suggest it is an important moment of democratization in Turkey while other aspects arouse scepticism. Three crucial indicators of a movement’s democratic potential are whether it attends to deciphering the existing constellation of power relations, reflects on the possibility of installing a counter-hegemony and gives importance to collective identities. However, the SC’s potential democratic contribution is weakened by its conceptualization of democratic struggle in terms of antagonism rather than agonism through ‘moralizing’ politics. Moreover, its reluctance to engage with institutions of representative democracy further complicates the matter. The main contribution of this study is its discussion of various forms of politicization and their possible effects on democratization; and to give some clues to the activists of different social movements that can be helpful in their self-reflection.     

Unemployment duration and personality

This paper focuses on the role personality traits play in determining individual unemployment duration. We argue that a worker’s job search intensity is decisively driven by her personality traits, reflected in her propensity to motivate and control herself while searching for a job. Moreover, personality traits, in as far as they can be signaled to a potential employer, may also enhance the probability of receiving and accepting a job offer.For our econometric duration analysis, we use the well-accepted taxonomy “Big Five” to classify personality traits. Based on individual unemployment data taken from the German Socio-Economic Panel (SOEP) our empirical findings reveal that the personality traits Conscientiousness and Neuroticism have a strong impact on the instantaneous probability of finding a job, where the former has a positive effect and the latter has a negative effect. The direction of the effect on the subsequent employment duration is the opposite. We do not find any significant effects of the personality traits Extraversion and Agreeableness on the duration of unemployment. The personality trait Openness eases finding a job only for female unemployed workers and workers with migration background.
