The mixture distribution models are more useful than pure distributions in modeling of heterogeneous data sets. The aim of this paper is to propose mixture of Weibull–Poisson (WP) distributions to model heterogeneous data sets for the first time. So, a powerful alternative mixture distribution is created for modeling of the heterogeneous data sets. In the study, many features of the proposed mixture of WP distributions are examined. Also, the expectation maximization (EM) algorithm is used to determine the maximum-likelihood estimates of the parameters, and the simulation study is conducted for evaluating the performance of the proposed EM scheme. Applications for two real heterogeneous data sets are given to show the flexibility and potentiality of the new mixture distribution. 相似文献

ABSTRACT We came together as editors of Decolonising the University through a commitment to understanding the university and our place within it; to examine what else might be possible for us, collectively, in the domain of higher education. Although we do not always agree about the university– or, perhaps more specifically, about the possibilities it contains for intervening effectively in the world– we nonetheless coalesced around an idea of ‘decolonising the university’ as an important strategic mode of engagement. Here, we set out the positions that we come from in relation to the broader debates about the university and its political possibilities and offer responses also to the reviews. These are not our final words on the matter, but words shaped by the political possibilities that present themselves at the outset of 2020 and which, we hope, will contribute to the increasingly necessary dialogues on this topic. 相似文献

Walker (1997) criticizes one of the conclusions in my book Tas?\iran (1995), that Heckman and Walker’s very high negative
wage rate and positive income effects on Swedish fertility are very sensitive. In this paper, I explain, first, that my results
are not only based on the series Walker mentions, but also on other series in both SFS and HUS data sets. Second, the combined
aggregate and micro wage series he criticizes is mainly derived with Heckman and Walker. Third, by discussing the points he
raises for the combination strategy, I show that his revised results are also supporting my conclusion.

The main purpose of this study was to investigate the effectiveness of the DSM-IV diagnostic criteria and the South Oaks Gambling Screen (SOGS) in identifying Turkish pathological gamblers. Fifty-nine subjects participated in the study. The subjects were diagnosed as either pathological gamblers or not (comparison group) through the use of the DSM-IV criteria and were given the Turkish version of the SOGS. Four of the ten DSM-IV criteria were found to be problematic in the diagnosis of Turkish pathological gamblers. The data concerning reliability and validity of the Turkish version of the SOGS suggested that the SOGS can be used as a reliable and valid instrument in identifying Turkish pathological gamblers. Most (16 out of 20) of the items of the SOGS appear to work well in discriminating pathological gamblers from the subjects in the comparison group. In the case of the two DSM-IV criteria and the four SOGS items that failed to discriminate, cultural factors seemed to be responsible for the failure. 相似文献

Management of contaminated sites is a critical environmental issue around the world due to the human health risk involved for many sites and scarcity of funding. Moreover, clean‐up costs of all contaminated sites to their background levels with existing engineering technologies may be financially infeasible and demand extended periods of operation time. Given these constraints, to achieve optimal utilization of available funds and prioritization of contaminated sites that need immediate attention, health‐risk‐based soil quality guidelines should be preferred over the traditional soil quality standards. For these reasons, traditional soil quality standards are being replaced by health‐risk‐based ones in many countries and in Turkey as well. The need for health‐risk‐based guidelines is clear, but developing these guidelines and implementation of them in contaminated site management is not a straightforward process. The goal of this study is to highlight the problems that are encountered at various stages of the development process of risk‐based soil quality guidelines for Turkey and how they are dealt with. Utilization of different definitions and methodologies at different countries, existence of inconsistent risk assessment tools, difficulties in accessing relevant documents and reports, and lack of specific data required for Turkey are among these problems. We believe that Turkey's experience may help other countries that are planning to develop health‐risk‐based guidelines achieve their goals in a more efficient manner. 相似文献

In this paper, we study many-to-one matching (hospital–intern markets) with an aftermarket. We first show that every stable
matching system is manipulable via aftermarket. We then analyze the Nash equilibria of capacity allocation games, in which
preferences of hospitals and interns are common knowledge and every hospital determines a quota for the regular market given
its total capacity for the two matching periods. Under the intern-optimal stable matching system, we show that a pure-strategy
Nash equilibrium may not exist. Common preferences for hospitals ensure the existence of equilibrium in weakly dominant strategies
whereas unlike in games of capacity manipulation strong monotonicity of population is not a sufficient restriction on preferences
to avoid the non-existence problem. Besides, in games of capacity allocation, it is not true either that every hospital weakly
prefers a mixed-strategy Nash equilibrium to any larger regular market quota profiles. 相似文献

In an effort to clarify alternative approaches to organizational analysis, this paper is concerned to stimulate the debate on how an inquiry into organizational phenomena, in general, and organizational learning, in particular, can be accomplished. Encouraging attention to different aspects of various paradigmatic approaches, the paper focuses on critical theory, postmodernism and social constructionism and how these paradigms have contributed and can contribute to the research in the subject domain of organizational learning. To this end, a paradigmatic review of the literature on organizational learning is offered in this paper. Organizational learning, as the study of learning processes of, and within, organizations, has attracted significant attention in academe since the early 1980s. There is a plethora of studies on organizational learning, which offer rich material for a paradigmatic review. This study highlights the need for further development of the field from alternative paradigmatic perspectives, with a view to generating more insights into the multifaceted, complex and changing nature of learning in contemporary organizations. 相似文献

This work aims to examine a possible change of feminist civil society pertaining to inclusivity with a particular interest in violence. It evaluates state-civil society relations, coping mechanisms with domestic violence and solidarity patterns with female refugees. It proposes a novel theoretical contribution, ‘feminization of refugee’ suggesting a positive shift in the empowerment of refugee women through bidirectional solidarity, intersectionality and resistance which consequently diversifies and invigorates the civil society itself. The findings suggest that the manifestation of a resistant civil society in Turkey inclined to withhold a strong feminist stance with a rights-based approach. The findings further manifest a growing need towards shelters in the pandemic experience which recalls capacity building requirements of civil society for refugee women against violence. 相似文献
