Effect of consumption choices on fluxes of carbon,nitrogen and phosphorus through households

Households are an important scale of analysis for human ecosystems because they are a major source of pollutants and could thus be a new focus for pollution management, particularly for education-based source reduction strategies. The household is also a meaningful unit for analysis of human ecosystems, being common to all human cultures. This study develops a Household Flux Calculator (HFC) to compute C, N, and P fluxes for scenarios intended to represent three levels of household consumption: low, typical, and high. All three scenarios were developed for suburban households with two adults and two children in the Minneapolis-St. Paul (Twin Cities) metropolitan area, Minnesota. Calculated ratios of fluxes between high and low consumption households were 3.5:1 for C, 2.7:1 for N and 1.4:1 for P. Results suggest a high level of discretionary consumption that could be reduced without a substantial reduction in standard of living. Thus, modest changes in behavior in high consumption households would greatly reduce fluxes of C, N, and P without major changes in lifestyle.

The Differential Perceptions of Male and Female Deviants

Abstract

Hepburn (1975) stated that the definition of the audience determines whether deviance exists so that societal reaction can take place. However, the audience has not received systematic attention in the literature of the sociology of deviance. The existing literature examines mostly the reactions of official social control agents. Consequently, the purpose of this research is to determine the stereotypes held by a group besides social control agents. Further, the research explores whether the sex of the deviant affects the stereotypes associated with deviant behaviors. The data were gathered from a sample of college students attending a small liberal arts college. Twelve types of deviants representing a wide variety of behavior patterns were evaluated using an Osgood semantic differential scale. The data show that the respondents perceived each type of deviant as having a different stereotype and that the stereotypes did not overlap. Furthermore, the stereotypes were not complex ones, nor all negative. The data further indicate that the sex of the deviant was influential in how people responded to that deviant.     

Senate confirmation of cabinet appointments: Congress-centered,presidency-centered,and nominee-centered explanations

Recent presidents find greater proportions of their executive nominations encountering substantial opposition in the Senate. What accounts for failed nominations to senior-level executive positions? We address this question by examining 297 cabinet and other senior-level nominations between 1969 and 2012, testing multivariate models of the effects of the partisan and ideological composition of the Senate, the president's public approval and electoral mandate, and characteristics of the nominee. The analysis demonstrates that allegations of illegal or unethical behavior by the nominee and concerns over policy preferences best explain the Senate's response to executive nominations. It is clear that, unlike legislative outcomes, confirmation outcomes are the products of nominee-centered factors with presidency-centered factors and Congress-centered factors having little impact on Senate decisions.     

The Impact of Fathers’ Work and Family Conflicts on Children’s Self-Esteem: The Hong Kong Case

Work and family conflicts are always viewed as issues of human resource management or occupational health. Insufficient attention has been focused on the impact on child development and quality of parenting, especially regarding the impact of a father’s work. To examine the impact of work and family conflicts on the quality of father–child interactions in Hong Kong, a cross-sectional survey was conducted. In total, 556 pairs of working fathers and their school-aged children participated in the survey. The findings of the survey indicated that fathers’ work-to-family conflicts negatively affected the quality of father–child interactions, which in turn caused harm to children’s self-esteem. In addition to work-family conflicts, a low income level of the fathers, a larger number of children in the family, and the presence in the family of children approaching adolescence were significant risk factors to the quality of father–child interactions. The mothers’ active parental involvement and the complexity of the fathers’ occupation were significant protective factors of the quality of father–child interactions. To facilitate strong family bonding and good quality parenting, possible measures to ensure a healthy work-family balance among working fathers are discussed.     

The Impact of Poverty on Children and Young People’s Use of Services

This article describes a qualitative study exploring the impact of poverty on children’s access to and use of services, which took a comparative approach to gather the views of children from more and less affluent households. Findings suggest affordability and related factors including limited mobility constrained service use for less affluent children, resulting in cumulative missed opportunities. However, extended family, friends and agencies facilitated service access, mitigating the impact of poverty on service use to some extent. Research implications include the importance of listening to and taking account of the views of children from lower income families in service planning.     

Bivariate compound poisson distributions

This paper discusses four alternative methods of forming bivariate distributions with compound Poisson marginals. Basic properties of each bivariate version are given. A new bivariate negative binomial distribution, and four bivariate versions of the Sichel distribution, are defined and their properties given.     

Building the S&T Digital Library at the Naval Research Laboratory

Abstract

The Ruth H. Hooker Research Library has been delivering digital information to researchers' desktops at Naval Research Laboratory (NRL) sites across the country for over ten years. This article describes the current and planned efforts at unifying the various journals, databases, reference tools, and linking schemes into a comprehensive and integrated Web-based scientific and technical digital library for the benefit of the NRL and the broader naval research community.

The warlord as arbitrageur

This article seeks to generate a more precise understanding of the emergence and perpetuation of warlords. First, it offers a simple, intuitive, and empirically grounded conceptual definition of warlordism. Second, it argues that the primary factor contributing to the success of warlords is the ability to take advantage of price differentials for political, economic, and cultural goods across terrains—in a word, to arbitrage. Third, it illustrates this model with a case study of Khun Sa (1934–2007), the self-proclaimed Shan freedom-fighter and “king” of Burma’s heroin trade. Finally, it suggests that the international community rethink its commitment to the norm of sovereignty in order to combat the proliferation of such non-state violence-wielders.     

Why Have Children in the 21st Century? Biological Predisposition, Social Coercion, Rational Choice

This review examines arguments and evidence pertaining to the question: why have children in settings where the net economic costs of children are clearly substantial? Thereview is organized around three themes: biologicalpredispositions, environment (social coercion) and rationalchoice. Specifically, we explore the argument that evolution hasproduced sets of genes that predispose persons to childbearing bymaking sex and parenthood pleasurable. We review sociologicalarguments regarding the pronatalism/antinatalism of societalinstitutions. Finally, we discuss arguments that stress therationality of childbearing decisions by appealing to biologicalpredispositions and the economic and non-economic values ofchildren. The authors speculate that while a modern socialstructure and rationale supportive of childbearing could beconstructed, such changes are not inevitable and may be difficultin the face of competing interests. Moreover, future social andtechnological change could alter the context of childbearingsubstantially. This uncertainty complicates policyrecommendations.
