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.     

Attachment Relationships and Psychological Adjustment of Married Adults

The present study explored relations among remembered parental (paternal and maternal) acceptance in childhood, spouse acceptance and psychological adjustment of adults. It also explored whether remembered childhood experiences of parental acceptance mediate the relation between perceived spouse acceptance and psychological adjustment. The sample consisted of 354 married adult men (178) and women (176). Results showed that the more accepting both men and women perceived their spouses to be, the better was their psychological adjustment. Similarly, the more accepting both men and women remembered their parents had been to them during childhood, the better was their psychological adjustment. Standard multiple regression analyses revealed that paternal acceptance mediated the relation between perceived spouse acceptance and the psychological adjustment of both men and women. In addition, remembered maternal acceptance mediated the relation between men’s (but not women’s) perceived spouse acceptance and psychological adjustment.     

College Men's Health in Practice: A Multidisciplinary Approach

Abstract

After a needs assessment indicated that male students underutilized campus health services, the San Francisco State University Student Health Service developed a coordinated complement of outpatient health services for men. The authors review their experience in developing, implementing, operating, and evaluating this ongoing clinical service. The needs assessment and subsequent program evaluation data suggest that male students on a large, culturally diverse, urban campus would respond favorably to targeted, multidisciplinary health initiatives that incorporate the principles of health promotion and disease prevention.     

Gavel-to-Gavel Congressional Television Coverage as Political Advertising: The Impact of C-Span on Legislative Sessions

This article examines the effect of television on the length of legislative sessions at the federal level in the United States. Data from the U.S. Congress during the period 1972–96 are employed, during part of which time each house of Congress received significant television coverage by C-SPAN and C-SPAN2. Evidence from a Parks regression suggests that the presence of C-SPAN has increased House sessions by 88–250 hours and the presence of C-SPAN2 has increased Senate sessions by a striking 252–431 hours, other things constant. Additional estimates suggest that House sessions are about two minutes longer per bill introduced under the eye of C-SPAN, and Senate sessions are about four minutes longer per bill introduced in the presence of C-SPAN2. Longer sessions, which represent low-cost forms of advertising for incumbents, are not without costs to taxpayers. We estimate that these costs lie somewhere between $16 million and $392 million in real terms per session of Congress.     

A Recipe for Change: Reclamation of Indigenous Food Sovereignty in O-Pipon-Na-Piwin Cree Nation for Decolonization,Resource Sharing,and Cultural Restoration

Abstract

O-Pipon-Na-Piwin Cree Nation (OPCN), an Indigenous community in northern Manitoba, Canada, was flooded and forced to relocate from ancestral lands to a nearby settlement under such circumstances. Regaining strength from their inherent cultural values grounded in their relationship with the land, OPCN eventually formed a community-based food program called Ithinto Mechisowin (IMP) (‘food from the land’). This article uses OPCN's concept of resource (wechihituwin) and decolonization (pasekonekewin) to present a nuanced understanding of Indigenous food systems in Canada. We argue that the ways in which IMP inspires reconnection with land, thereby improving access to culturally appropriate healthy food, are steps forward in strengthening Indigenous food sovereignty.     

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.     

Estimation and prediction of Marshall–Olkin extended exponential distribution under progressively type-II censored data

In this paper, we consider Marshall–Olkin extended exponential (MOEE) distribution which is capable of modelling various shapes of failure rates and aging criteria. The purpose of this paper is three fold. First, we derive the maximum likelihood estimators of the unknown parameters and the observed the Fisher information matrix from progressively type-II censored data. Next, the Bayes estimates are evaluated by applying Lindley’s approximation method and Markov Chain Monte Carlo method under the squared error loss function. We have performed a simulation study in order to compare the proposed Bayes estimators with the maximum likelihood estimators. We also compute 95% asymptotic confidence interval and symmetric credible interval along with the coverage probability. Third, we consider one-sample and two-sample prediction problems based on the observed sample and provide appropriate predictive intervals under classical as well as Bayesian framework. Finally, we analyse a real data set to illustrate the results derived.     

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.
