Interrogating the tribal: the aporia of ‘tribalism’ in the sociological study of the Middle East

In this paper, we intend to deconstruct the term ‘tribalism’ as a colonial category, which figures as a prominent concept in social studies on Kurds as well as the Middle East at large. Blithely used, tribalism has occupied a central place, especially in the existing scholarship on Kurdistan. Some earlier anthropological works have gone so far as to regard tribalism as the ‘DNA’ of Middle Eastern people. Drawing on recent studies on Latin America, Africa and Central Asia, we argue that the use of tribalism as if it is the natural constitution of Kurdish society has caused a significant misrepresentation and oversimplification of socio‐political life in Kurdistan as well as the broader Middle East. In a way, the existing body of scholarship on this region has reproduced statist‐nationalist discourses at the expense of dominated communities (e.g., Kurds). The historical context of both colonial powers and nation‐states ‘combating tribes and tribalism’ coincided with the emergence of the discourse of racial biopolitics. Thus, the use of the term tribalism to define certain nations or ethnic groups should not be viewed as merely an application of socio‐anthropological categories. Hence, we argue that the ethical aspects and implications of the use of tribalism by both colonial powers and later by nation‐states to define certain ethnic groups must not be overlooked.     

On some generalized ageing orderings

Some partial orderings that compare probability distributions with the exponential distribution are found to be very useful to understand the phenomenon of ageing. Here, we introduce some new generalized partial orderings which describe the same kind of phenomenon of some generalized ageing classes. We give some equivalent conditions for each of the orderings. Inter-relations among the generalized orderings have also been discussed.     

On progressively censored inverted exponentiated Rayleigh distribution

In this paper, we discuss a progressively censored inverted exponentiated Rayleigh distribution. Estimation of unknown parameters is considered under progressive censoring using maximum likelihood and Bayesian approaches. Bayes estimators of unknown parameters are derived with respect to different symmetric and asymmetric loss functions using gamma prior distributions. An importance sampling procedure is taken into consideration for deriving these estimates. Further highest posterior density intervals for unknown parameters are constructed and for comparison purposes bootstrap intervals are also obtained. Prediction of future observations is studied in one- and two-sample situations from classical and Bayesian viewpoint. We further establish optimum censoring schemes using Bayesian approach. Finally, we conduct a simulation study to compare the performance of proposed methods and analyse two real data sets for illustration purposes.     

Divide and rule: The effects of diversity and network structure on a firm's sustainability performance

To tackle sustainability, firms often use partnerships with organizations from different industries or societal sectors such as government and civil society. While partnerships show potential for firms to improve their sustainability performance, they not only lead to a potential to learn from diversity but also to tensions due to a lack of unity between partners. In partnerships for sustainability, this unity-diversity tension particularly manifests itself in different views of sustainability. This paper examines how this tension affects the sustainability performance of firms taking part in partnerships for sustainability in developing countries. To address this question, this tension is conceptualized as being the result of differences in organizational frames and institutional logics between a focal firm and other organizations in the partnership. It is also taken into consideration that firms are embedded in an overarching, relational network structure that allows them to manage the diversity in frames and logics. To test the hypotheses, the study analyses 1353 greenhouse gas emission reduction projects of 322 firms from developing countries active in the carbon-offset market from 2007 to 2009. The findings show that if partners hold different frames and belong to different sectors, a firm's sustainability performance improves first due to learning from diversity but after a turning point decreases from a lack of unity. This inverse U-shape relationship is flipped if a firm occupies a brokerage position in its network.     

Gays,Guys, and Mchicha Mwiba: Same-Sex Relations and Subjectivities in Dar es Salaam

Drawing on 15 months of fieldwork, this article explores ways in which same-sex relations are perceived and performed in Dar es Salaam, Tanzania. While several different constructions of same-sex sexuality coexist in Dar es Salaam, it is common to conceive of same-sex practicing men as falling into two main categories. Men belonging to each of these differ with respect to the corporeal, gendered, and social positions that are open to them, and typically form dyads across the conceptual boundary of difference that runs between them. The article speaks to the importance of examining sexuality and gender in particular sociocultural settings.     

Some comments on sample quantiles for dependent observations

Sample quantiles obtained from a linear process are examined and their asymptotic properties are derived by using simple elementary arguments.     

Rapid Response to a Conjunctivitis Outbreak: The Use of Technology to Leverage Information

Abstract

When an outbreak of conjunctivitis was identified at a rural New England college early in 2002, the college health center medical staff used various information management and communication systems to alert the community to the situation. They called upon the state Department of Human Services and the Centers for Disease Control and Prevention to help them understand and manage the outbreak. Technological systems already in place at the college allowed for rapid collection of data by means of a survey delivered over the Internet and a carriage study facilitated by a Web-based appointment and communication system. Within days, the data were collected and analyzed and an immediate response to contain the outbreak was launched.
