The Cognitive Domain of the Quality of Life of University Students: A Re-Analyses of an Instrument

This paper presents the re-analysis of a previouslypublished instrument, based on Bloom's taxonomy,developed to measure the cognitive domain of thequality of life of university students. The items inthis instrument were assessed using Guttman's SmallestSpace Analysis. The findings generally supportBloom's conceptualization, identifying 5 of 6dimensions in the taxonomy: Knowledge, Comprehension,Application, Analysis, and Evaluation. The findingsprovide support for the enduring utility of Bloom'staxonomy, and reinforce the ongoing need to testtheoretically informed instruments using sophisticatedstatistical techniques.     

The demography of Tristan da Cunha

The eruption of the volcano on Tristan da Cunha in 1961 and the subsequent arrival of the island population in the United Kingdom provided a unique opportunity for studying the health of this formerly isolated community. During their stay, while the facilities and services of modern medicine were made available to them, investigations of many facets of their general biology were made under the auspices of the Medical Research Council, co-ordinated by Dr. H. E. Lewis. Analysis of their demographic history was essential to understand many features of their disease pattern, and the results of this analysis are presented here. They are of interest in that they not only show some consistent trends in the common variables of demography, but also demonstrate biological principles, some perhaps for the first time in man, which may be fundamental in the process of colonization as a biological phenomenon, e.g. the initial difficulty of establishment of a population in a new area, the curious demographic structure that may emerge in its earliest years, the bottleneck effect of population-size reduction, the founder principle.     

Going Back Home? Changing Demography and Geography of Mexican Return Migration

Return migration has been a constant feature of Mexico?CUS migration patterns, but its characteristics have changed sharply with time. We use the Mexican censuses and counts of 1995, 2000, 2010, and the complete set of individual and household records of the 2005 Population Count to explore the demographic characteristics of returnees in the context of tighter border control and rising levels of forced return migration. Involuntary and therefore unplanned return is likely to mean greater difficulties of incorporation into the community of origin. The study of the effects of the militarization of the US?CMexico border on migration patterns has focused on the US side. We contribute to this literature by focusing on the Mexican side. We consider the intensity and type of previous migration to the US as compared to current return migration, and State of origin and destination. Our data suggest that particularly attractive destinations for returnees are border cities, prosperous communities and growing metropolitan areas. Findings suggest changes in the demographic composition and geographic distribution of returnees. The discordance between the patterns of outmigration and return is a telling indicator of changes in the overall migration relationship between Mexico and the US. The patterns for 2005 are also observed in 2010 even if the absolute number of inter-censal returnees increased threefold over the period. Finally, we argue that focusing on destinations of return instead of areas of emigration will contribute to a more comprehensive understanding on the nature of future return migration to Mexico and its policy implications.     

Human Rights and Sociological Duties

In recent years, scholars from a range of disciplinary orientations have looked to human rights to address an exceedingly complex, and often tragic, array of social problems. Nevertheless, as Judith Blau ( 2016 ) and many others have noted, despite the best efforts of dedicated supporters, people still remain separated from their rights. Why has realizing the promise of rights proven to be so elusive, and what can scholars do to help connect people with their rights?     

Six for Lunch: A Dining Option for Residents with Dementia in a Special Care Unit

Recent research has focused on the design of special care units for residents with dementia, often identifying the social benefits of residentially scaled kitchen and dining areas. This qualitative case study examines how the environmental design features of two dining settings in one special care unit impact residents’ patterns of socialization and interaction at meal times. The first setting is a central dining room for 50 to 60 residents. The second setting is a small office with a residentially scaled kitchen, where once a week, the activity director invites six residents for lunch once a week. Within an ecological theoretical framework, the study findings reveal that, while mealtimes in both settings are highly anticipated, it is the complex relational ties between the operational, managerial, and environmental features of the settings which determine residents’ social interaction and satisfaction with their mealtime experiences.     

Reverse Regression,Fairness, and Employment Discrimination

Possible salary discrimination can be studied by comparing mean salaries of, say, males and females, after statistical adjustment for differences in job qualifications. The adjustment is often made by regression, with salary as dependent variable, and job qualifications and sex as independent variables. One might also regress job qualifications on salary and sex, a procedure called reverse regression. Ideas about fairness as well as technical concepts are relevant to discrimination studies. There are two distinct aspects of fairness, one based on comparisons of salary and the other based on comparisons of qualifications. Both concepts are needed to evaluate fairness.     

For what use are tests of hypotheses and tests of significance

Tests of sharp null hypotheses, although frequently computed, are.rarely appropriate as the major end product of statistical analyses, except possibly in some, areas of the natural sciences. But procedures closely akin to tests, although often less formal, are needed in almost every investigation in which exploratory data analysis is used to help to decide upon the statistical model appropriate for the final analysis. The term “diagnostic check”has been suggested by Box and Jenkins for these procedures. Traditional statistical tests often suggest useful diagnostic checks -and this, in my view, is what tests are mainly good for-but visual examination and interpretation of data plots are often equally important. Biere is also much to be gained by the development of new diagnostic checks, and testing theory may be useful as one guide to this development.     

The effects of economic circumstances on British students' mental and physical health

Three-hundred sixty British university students completed a questionnaire providing information on demographic characteristics, financial circumstances, smoking, and drug and alcohol use. A 14-item inventory of physical symptoms, the short form 36 health survey (SF-36), and the General Health Questionnaire (GHQ-12) were used to assess their physical and psychological well-being. Except for physical functioning, all subscales of the SF-36 and the GHQ indicated levels of health significantly below population norms matched for age and sex. Poorer mental health was related to longer working hours outside the university and difficulty in paying bills. Students who had considered abandoning study for financial reasons had poorer mental health, lower levels of social functioning and vitality, and poorer physical health as indicated by variables on the SF-36. They were also heavier smokers. Students' personal debt was significantly associated with their knowing people involved in prostitution, crime, or drug dealing to help support themselves financially.     

Markov-chain monte carlo: Some practical implications of theoretical results

We review and discuss some recent progress in the theory of Markov-chain Monte Carlo applications, particularly oriented to applications in statistics. We attempt to assess the relevance of this theory for practical applications.
