Sociopolitical control among parents of school-age children in a post-socialist city

This study explored sociopolitical control among parents of school-age children in a suburban municipality of a large post-socialist city. The participants completed a questionnaire that asked them about their sense of sociopolitical control in terms of leadership competence and policy control, as well as about other aspects of their lives, including mental health. The findings show that the participants have a greater sense of sociopolitical control in terms of leadership competence than in terms of policy control. Moreover, the findings show that voting in the last presidential election and degree of depression influenced negatively the sense of leadership competence among parti-cipants. Within the context of empowerment, the findings have implications for practice which focuses on consumer-based activities that allow citizens more leadership opportunities and control at the local level. Future research is needed that replicates this study, taking into account its limitations. In order for citizens in post-socialist countries to create civil societies at the same time that they implement market economies, they must be empowered. Some evidence suggests that several factors, including mental health problems, may influence the sense of empowerment among citizens in post-socialist coun-tries. Within the context of empowerment, this study examines sociopolitical control among citizens in a suburb of a large post-socialist city. The findings in the study have implications for social welfare practice in this city and for future research.     

On Large Deviations of Sums of Independent Random Variables

Extensions of some limit theorems are proved for tail probabilities of sums of independent identically distributed random variables satisfying the one-sided or two-sided Cramér's condition. The large deviation x-region under consideration is broader than in the classical Cramér's theorem, and the estimate of the remainder is uniform with respect to x. The corresponding asymptotic expansion with arbitrarily many summands is also obtained.     

On lower bounds for tail probabilities

Chebyshev's inequality and its generalizations make it possible to give upper bounds for the tail probabilities in the distribution of a random variable. We present a method of finding lower bounds for these probabilities . The method is based on improvements of the Lyapunov inequality for moments of a random variable.     

Revising the Harris-Todaro framework to model labour migration from the Canadian Northern frontier

The Harris-Todaro model of labour migration was developed almost four decades ago, and since has become a classic method of migration analysis in less developed countries. This paper explores the applicability of the Harris-Todaro (HT) framework outside its traditional use, by modelling frontier-metropolis migration in Canada. If appropriate, the framework can potentially be used in other countries with similar regional dichotomies, such as Russia and Australia. The paper argues that the HT model is generally applicable in the context of migration from the resource frontier to large metropolitan areas of the Canadian south, although it requires several modifications. The classic HT model is extended to account for northern labour-force heterogeneity (Aboriginal and Non-Aboriginal), the possibility of having or losing jobs in the declining and undiversified frontier economy, and living cost differentials. Further analysis is focused on Aboriginal migration from isolated northern communities. The plausibility of the modified HT model is demonstrated using an empirical test, in which the model is used to assess migration probabilities of Aboriginal labour migrants. These new insights into the mechanisms of frontier-metropolis migration could provide a better basis for developing planning strategies, aimed to sustain human capital in the Canadian North, and for optimizing welfare policies both in the North and in the South.     

Large Deviations for Sums of Independent Non Identically Distributed Random Variables

This article considers large deviation results for sums of independent non identically distributed random variables, generalizing the result of Petrov (1968 Petrov , V. V. ( 1968 ). Asymptotic behavior of probabilities of large deviations . Theor. Probab. Appl. 13 : 408 – 420 . [Google Scholar]) by using a weaker and more natural condition on bounds of the cumulant generating functions of the sequence of random variables.     

Cross‐Cultural Measurement Invariance of Adolescent Self‐Report on the Pediatric Quality of Life Inventory™ 4.0

This study evaluated the cross‐cultural measurement invariance of the Pediatric Quality of Life Inventory version 4.0 (PedsQL^?) among adolescents sampled from Bulgaria, Croatia, India, Indonesia, Nigeria, Serbia, and Turkey. The multiple‐indicator multiple‐cause (MIMIC) model was used, which allowed controlling of demographic variables (i.e., age, gender, and socioeconomic status). Significant effects of country on scores within the PedsQL^? domains were observed, with up to 17 items showing differential item functioning (DIF) across the countries. We did not find support for cross‐cultural measurement invariance hypotheses for scores on the PedsQL^? adolescent self‐report in this study. Researchers should use caution in making cross‐cultural quality of life comparisons while using the PedsQL.
