A Family System Approach to Investigate Family‐Based Pathways Between Financial Stress and Adolescent Problem Behavior

This article proposes a family system approach to improve our understanding on family stress processes. Examining effects within (actor) and between (partner) parents, we explored family‐based pathways through which financial stress is associated with adolescent externalizing problem behavior. Data from 340 families were analyzed, with both parents rating their financial stress and parenting stress, and parents as well as adolescents rating the parent–child communication and adolescent problem behavior. The results revealed that the association between financial stress and adolescent externalizing problem behaviors was mediated by parenting stress and parent–child communication. Although our results provided evidence for both actor and partner effects, actor effects were more prominent. No parent gender differences were found in the strength of the pathways.     

New flexible models generated by gamma random variables for lifetime modeling

In this paper we introduce a new three-parameter exponential-type distribution. The new distribution is quite flexible and can be used effectively in modeling survival data and reliability problems. It can have constant, decreasing, increasing, upside-down bathtub and bathtub-shaped hazard rate functions. It also generalizes some well-known distributions. We discuss maximum likelihood estimation of the model parameters for complete sample and for censored sample. Additionally, we formulate a new cure rate survival model by assuming that the number of competing causes of the event of interest has the Poisson distribution and the time to this event follows the proposed distribution. Maximum likelihood estimation of the model parameters of the new cure rate survival model is discussed for complete sample and censored sample. Two applications to real data are provided to illustrate the flexibility of the new model in practice.     

Making environmental sociology sociological

Three basic sociological distinctions—viewing the environment as home or place of sustenance, separation of home and workplace, and “thing” work versus “people” work—are used to illuminate such sociological concerns as environmental degradation as a social problem, social specialization and pollution, and the demographic profiles of environmentally concerned people.     

Tell Your Stories about China

I have just finished writing my new book and I appreciate the efforts of everyone who has written stories for "My Foreign Teacher and I "essay contest. Those which I read left me with the knowledge that their experiences were all worth sharing and writing about. Whether foreign teachers or Chinese students, both have had     

The Kumaraswamy generalized gamma distribution with application in survival analysis

We introduce and study the so-called Kumaraswamy generalized gamma distribution that is capable of modeling bathtub-shaped hazard rate functions. The beauty and importance of this distribution lies in its ability to model monotone and non-monotone failure rate functions, which are quite common in lifetime data analysis and reliability. The new distribution has a large number of well-known lifetime special sub-models such as the exponentiated generalized gamma, exponentiated Weibull, exponentiated generalized half-normal, exponentiated gamma, generalized Rayleigh, among others. Some structural properties of the new distribution are studied. We obtain two infinite sum representations for the moments and an expansion for the generating function. We calculate the density function of the order statistics and an expansion for their moments. The method of maximum likelihood and a Bayesian procedure are adopted for estimating the model parameters. The usefulness of the new distribution is illustrated in two real data sets.     

The Drug‐Laden Balloon: U.S. Military Assistance and Coca Production in the Central Andes*

Objective. This article explores the empirical effects of U.S. drug policy on coca cultivation in the Central Andes. We assess the impact of U.S. military assistance on the production of coca in the Central Andes, while controlling for other explanatory variables that influence coca cultivation. Method. Using data from 1980–2001 for Colombia, Bolivia, and Peru, we perform a pooled cross‐sectional time‐series analysis. Results. The effects of U.S. military assistance on coca cultivation are not uniform across the Central Andes. Coca production decreased in Bolivia and Peru and increased in Colombia. Total coca production in the Central Andes, however, remained unchanged. Conclusion. This study is consistent with existing literature that points out the obstacles governments face as they attempt to suppress illicit goods. Specifically, our empirical findings support the idea of the “balloon effect,” whereby government efforts to “squeeze” illicit trade in one area result in the expansion of that trade elsewhere.     

A Response to Social Problems in Developing Countries

This paper considers social development as a relatively new concept, and new practice model. Its definition still lacks concreteness. Here it is viewed as a process of planned institutional change to bring about a better fit between human needs and social policies and programmes (Sanders, 1982); it is not satisfactory to measure development in purely economic terms, for this has resulted in the marginalization of the majority of the population in developing countries. The curative and remedial functions adopted by the social work profession in accordance with the dictates of the modernization approach, have rendered social work unable to address itself meaningfully to the problem of marginalization or mass poverty. Social development rests upon social policies that are promotive of human needs and this is only possible in circumstances where such policies are a product of the people's participation.     

Hair loss and electability: The bald truth

This study probes one particular component of the well documented linkage between personal appearance and impression formation by investigating the extent to which and the mechanisms through which bald and balding men are underrepresented in high elective office. Study 1 compares the prevalence of hair loss among governors and members of Congress, on the one hand, and the general public, on the other, and concludes that officeholders are much more likely to have a full head of hair than would be expected of men of their age. Study 2 poses an experimental test of voter bias against bald and balding candidates by presenting voters in a simulated congressional race with materials depicting otherwise identical candidates in either their natural bald or balding condition or wearing a professionally fitted hairpiece. No voter bias against bald or balding candidates is apparent, a finding that suggests that the causal mechanism underlying underrepresentation of bald and balding men is not voter bias.Ugly is a field without grass, a plant without leaves, or a head without hair (Ovid, quoted by Klenhard, 1986, p. 11).Politics represents an area of public life in which the effects of appearance may lead to very important social consequences and in which the idea of special privilege for the pretty is particularly repellent (Efran and Patterson, 1975, p. 352).The authors thank Judee Burgoon, Michael Burgoon, and Carol Sigelman for useful comments and suggestions, and Brandt Baker, Henry Ewbank, Jeff Gardner, Henry Kenski, Dan Singer, and David Williams for their assistance with this project.
