Joint tests of non-nested models and general error specifications

This paper is concerned with joint tests of non-nested models and simultaneous departures from homoskedasticity, serial independence and normality of the disturbance terms. Locally equivalent alternative models are used to construct joint tests since they provide a convenient way to incorporate more than one type of departure from the classical conditions. The joint tests represent a simple asymptotic solution to the “pre-testing” problem in the context of non-nested linear regression models. Our simulation results indicate that the proposed tests have good finite sample properties.     

Reconceptualizing migration as a household phenomenon: outmigration from New York City by race and Hispanic origin

"This paper proposes a conceptual framework for analyzing migration as a household event and presents two public use microdata applications of this approach for out-migrants from New York City. The distribution of single- and multi-origin households by race and Hispanic origin permits a more rigorous analysis of household migration differentials....and the disaggregation of household members by migration status provides insight into the household outcomes of the migration process...."

The use of a model in long term planning—A case history

Long term planning in companies can range from the partial simplistic approach to a structured time-consuming ritual. Either extreme can bring planning into disrepute, and both reflect the lack of the proper tools of the trade. Models, by themselves, are no panacea, but properly conceived, constructed, and developed they can transform the planning process. The key to effective and practical models is use, and this can be achieved through direct management involvement on the model's development, and by making sure the model is basically simple and flexible. This article describes how such a model was constructed using a modular approach, and how it was used effectively in long term planning.     

Cross Validation of the Gambling Problem Severity Subscale of the Canadian Adolescent Gambling Index (CAGI/GPSS) on a Sample of Ontario High School Students

This paper reports on the cross validation of the Gambling Problem Severity Subscale of the Canadian Adolescent Gambling Index (CAGI/GPSS). The CAGI/GPSS was included in a large school based drug use and health survey conducted in 2015. Data from students in grades 9–12 (ages 13–20 years) derived from the (N = 3369 students). The CAGI/GPSS produced an alpha of 0.789. A principle component analysis revealed two eigenvalues greater than one. An oblique rotation revealed these components to represent consequences and over involvement. The CAGI/GPSS indicated that 1% of the students fell into the “red” category indicating a severe problem and an additional 3.3% scored in the “yellow” category indicating low to moderate problems. The CAGI/GPSS was shown to be significantly correlated with gambling frequency (r = 0.36), largest expenditure (r = 0.37), sex (more likely to be male) (r = ?0.19), lower school marks (r = ?0.07), hazardous drinking, (r = 0.16), problem video game play (r = 0.16), as well as substance abuse. The CAGI/GPSS was cross validated using a shorted version of the short SOGS, r = 0.48. In addition the CAGI/GPSS and short SOGS produced very similar patterns of correlations results. The results support the validity and reliability of the CAGI/GPSS as a measure of gambling problems among adolescents.     

Feminism and Imperialism, 1890–1920: Our Anti‐Imperialist Sisters—Missing in Action from American Feminist Sociology*

This article retrieves part of our historical past to address two omissions in American feminist sociology on the subject of global imperialism. The first section addresses the inadequate attention feminist sociologists have paid to how major leaders of the women's movement responded to U.S. overseas expansion in the late nineteenth and early twentieth centuries. It documents how these early feminists had both progressive and reactionary responses to the anti‐imperialist struggles of their era. Particular emphasis is given to how issues of race, class, and gender were interwoven in their discourses on imperialism. The second section focuses on how the writings of the most famous woman theorist and critic of imperialism during this era—Rosa Luxemburg—are virtually ignored in U.S. portrayals of feminist sociology and women founders of sociology. To address this omission, Luxemburg's theory of imperialism is examined, as well as how it has influenced contemporary global feminist works. A critical analysis of these Luxemburg‐inspired works considers their implications for understanding global imperialism today. In this way, the past is used to clarify the present.     

Out of the shadows?: Grandfatherhood,age and masculinities

Recent years have witnessed an increasing recognition of the role of grandparents in contemporary families. However, there has been little if any research which emphasises the roles and relationships of grandfathers. And while the more limited contribution of grandfathers compared to grandmothers remains a widespread perception, recent studies suggest that the importance of grandfatherhood for men has been considerably underestimated. Through reviewing the place of grandfathers within grandparenthood research, the article argues that understandings of grandfathers in terms of gender difference can be seen to reflect a feminised conception of grandparenting derived from the experience of grandmothers. The article then builds on this review by exploring how intersections of age identity and masculinity may influence the different ways in which grandfatherhood is understood and enacted.     

A scientist's viewpoint on promoting effective use of experimental design: Ten things a scientist wants to know about experimental design

This paper tackles the practical application of statistical tools. Chemical development is a rich area for collaboration between statisticians and chemists, but most statisticians encounter difficulties in promoting the tools to this client group. This paper, presented from a chemist's perspective, is intended to help bridge the gap between the two professions. The paper explores differences in uptake and attitudes towards adopting these techniques and suggests what has hindered or helped the process of effective application of experimental design.
