Population estimates for Bangladesh: The use of a specific transitional population model

Summary The development of population in Bangladesh was affected by a succession of man-made and natural calamities, such as the Bengal Famine of 1943, refugee movements following the partition of India and Pakistan in 1947, devastating floods and cyclones around 1970, and the military action during the war of liberation. Though there had been a tradition of census taking and vital registration in Bangladesh, as part of the Indian sub-continent, extending for over a century, vital registration was so deficient as to be almost valueless, and there were gross misstatements of age and under-enumeration in the censuses. In the census of 1941, on the other hand, political manoeuvring led to a substantial overcount of the population. In this paper, Bangladesh population trends are studied within the broader framework of the subcontinent, taking account of plausible differentials. A considerable element of uncertainty was introduced into growth trends as a result of variations in the completeness of census-taking and of unrecorded refugee and labour movements across open land borders. In this connection the substantial inflationary bias associated with techniques of population estimation using the dual record system is discussed. The application of stable population models is even less justified in Bangladesh with its history of declining mortality. A transitional age structure model was constructed on the basis of the information available on declining mortality and accelerating growth and the model was made even more specific by modifications which took care of the impact of recent calamities and of unrecorded migration. The population base of the census of 1961 was adjusted in accordance with this model. The local mortality age pattern was used in projecting the population by sex and age groups to the date at which the census was originally due to be taken in 1971, and to the date when it was actually taken in March 1974. The post-1970 calamities and their effect on mortality were ignored. The aggregate estimate of population of 72.9 million in March 1974 is slightly in excess of the census count (by about two per cent) reported provisionally as 71.3 million. The excess in our estimate could be accounted for by the losses due to cyclone and military action.     

Test of the demands, supports-constraints framework in predicting psychological distress amongst Australian public sector employees

This paper describes the demands, supports-constraints framework originally articulated by Payne (1979) for predicting psychological distress, and reports the results of an empirical study involving 2452 white-collar, public sector employees in Australia. The study uses hierarchical regression to test for the interaction effects of the demands and constraints variables, having applied suitable controls for instance by including trait anxiety and removing curvilinear effects. The results reveal little evidence of an interactive effect but moderately strong main effects and modest support for the value of controlling for curvilinear effects. Trait anxiety is shown to have a strong effect on psychological distress and considerably reduces the size of the relationship between demands, supports-constraints and psychological distress when statistically controlled for. However, it still accounts for 18.7% of the variance when entered last in the regression and it is recommended that its effects be explored in all studies of stress that rely on self-report data.     

How Does Centrality in Coopetition Networks Matter? An Empirical Investigation in the Mobile Telephone Industry

This research examines how a firm's position in a coopetitive network (formed through cooperation among firms within an industry) influences the extent of the firm's competitive aggressiveness and market performance. The authors collected data on the competitive and cooperative actions of firms in the mobile telephone industry from 2000 to 2006, using structured content analysis of news reports. The results show that the centrality of a firm in a coopetitive network contributes to the firm's competitive aggressiveness through increased volume and variety of competitive actions. Further, the more central a firm is in the network, the greater is its market performance. Firms that undertake more volume and variety of competitive actions improve their market performance. Overall, these results show that being in a central position in a coopetition network is quite advantageous for the firm.     

Socioeconomic determinants of the intra-family status of wives in rural India: Analysis and empirical evidence

Relying on a structured survey of 117 wives in four rural villages in the Midnapore District of West Bengal, this article investigates the influence on the intra-family status of wives of variables that may increase the bargaining power of wives in their family. Saveral indicators of status are considered and investigated using the ANOVA technique and probit analysis. The main hypothesis considered is whether the results support bargaining theories of the intra-household status of wives or the view that gender status is primarily determined in Indian society by social customs and the patriarchal structure of society. Given the overall patriarchal structure of Indian society, the results indicate that bargaining theories are at best only marginally relevant. Situations that result in greater bargaining power for wives in Western societies do not necessarily do so in north India given the total pervasiveness of its patriarchal society.

MANAGEMENT INFORMATION SYSTEMS CURRICULA: STATE-OF-THE-ART*

Business and business/management schools were surveyed to determine the characteristics of management information systems (MIS) curricula. All academic degree levels–Bachelors, Masters, and Doctorate–were investigated. An encouraging 82% response from 260 academic institutions queried lends credibility to findings reported. These survey results should provide insights for the development of new and/or revised MIS curricula. They also indicate opportunities for expanding enrollments. The MIS field, still in its infancy, has not yet stabilized. This is causing difficulties in planning curricula for this newly-evolving discipline. The MIS area within both the academic and business communities is undergoing constant and rapid change due to environmental and technological advancements. In order to insure curriculum relevance and properly trained personnel in this field, these areas must respond to these changes. Suggestions as to where and how this discipline should proceed must be based upon the currently existing situation.     

Sampling Richness and Qualitative Integrity: Challenges for Research With Families

Sampling is one of the most difficult and contentious aspects of qualitative research design. There are few guidelines for sampling decisions or for understanding saturation in qualitative family research. The authors frame the problematic of data quality in the selection of units of analysis and observation and consider how to enhance sample richness. They outline considerations for data quantity and sample size as well as case‐ and variable‐based approaches. With multiple examples from recent and classic studies to illustrate the consequences of sampling decisions, they explore links between saturation and validity. Finally, they encourage researchers to craft a coherent statement on qualitative integrity to demonstrate how their sampling decisions are rooted in epistemology, theory, and richness and quality of data.     

Associations Between Friendship,Sympathy, and Prosocial Behavior Toward Friends

The current study examined the associations between multiple aspects of the friend relationship (connection, companionship, psychological control) and global prosocial behavior toward friends. Participants included 467 early adolescents (M age of child = 13.32, SD = 1.05, 49% female, 69% European American), and data were collected at two time points, roughly 1 year apart. Structural equation modeling suggested that friend psychological control was negatively associated with prosocial behavior toward friends, while friend connection was positively associated (via adolescent sympathy). Discussion focuses on the friend relationship as an important influence on adolescent sympathy and prosocial behavior toward friends.     

Yearlong physical activity and health-related quality of life in older Japanese adults: the Nakanojo Study

We hypothesized that the health-related quality of life (HRQOL) would be poorer in physically inactive older adults. This was tested in a sample of 73 male and 108 female free-living healthy Japanese participants, age 65-85 years. We measured accelerometer step counts and their metabolic equivalents (METs) throughout each 24-hr period for 1 year. At the end of the year, HRQOL was assessed. Physical activity was grouped into quartiles. HRQOL was poorer in the lowest quartiles of participants with respect to both step count and duration of activity >3 METs; however, our sample showed no better HRQOL in those participants exceeding minimum standards of daily physical activity, corresponding to counts of around 5,500 and 4,500 steps/day and durations of around 13 and 14 min/day in men and women, respectively. Causation cannot be demonstrated from this cross-sectional study, but nevertheless we suggest that elderly individuals should be encouraged to meet such standards of habitual physical activity.
