Parenthood and Marital Satisfaction: A Meta‐Analytic Review

This meta‐analysis finds that parents report lower marital satisfaction compared with nonparents (d=?.19, r=?.10). There is also a significant negative correlation between marital satisfaction and number of children (d=?.13, r=?.06). The difference in marital satisfaction is most pronounced among mothers of infants (38% of mothers of infants have high marital satisfaction, compared with 62% of childless women). For men, the effect remains similar across ages of children. The effect of parenthood on marital satisfaction is more negative among high socioeconomic groups, younger birth cohorts, and in more recent years. The data suggest that marital satisfaction decreases after the birth of a child due to role conflicts and restriction of freedom.     

The Economics of the Counter-Reformation: Incumbent-Firm Reaction to Market Entry

The Catholic Church reacted to the Protestant Reformation by taking on the defensive posture of an incumbent-firm monopoly fighting to survive in the face of new competition. Contemporary firms typically respond to rival entry by rewriting their corporate charter. So did the medieval Catholic Church. But the Council of Trent failed as a reorganization plan because to keep economic rents flowing as before, it left intact the distribution of powers and property rights among the governing body of pope and cardinals—thus demonstrating that entrenched economic interests are powerful inducements to behavior, even in spiritual institutions.     

Functional Modelling and Classification of Longitudinal Data*

Abstract. We review and extend some statistical tools that have proved useful for analysing functional data. Functional data analysis primarily is designed for the analysis of random trajectories and infinite‐dimensional data, and there exists a need for the development of adequate statistical estimation and inference techniques. While this field is in flux, some methods have proven useful. These include warping methods, functional principal component analysis, and conditioning under Gaussian assumptions for the case of sparse data. The latter is a recent development that may provide a bridge between functional and more classical longitudinal data analysis. Besides presenting a brief review of functional principal components and functional regression, we develop some concepts for estimating functional principal component scores in the sparse situation. An extension of the so‐called generalized functional linear model to the case of sparse longitudinal predictors is proposed. This extension includes functional binary regression models for longitudinal data and is illustrated with data on primary biliary cirrhosis.     

Reproducibility of clinical data I: continuous outcomes

Across a variety of clinical settings, repeated measurements on an individual, obtained under identical circumstances, often differ from one another. This implies the measurements lack perfect reproducibility. Topics related to reproducibility of clinical measurements are introduced in this paper. In this first of two parts, continuous outcomes are addressed. The intraclass correlation coefficient, ρ, has been the traditional coefficient of reproducibility for continuous outcomes. The importance of ρ regarding observations on an individual, and observations among populations, is outlined. Estimation and inferential procedures for ρ are reviewed and worked examples are provided. Copyright © 2004 John Wiley & Sons, Ltd.     

Stress Hormone Changes and Marital Conflict: Spouses’ Relative Power Makes a Difference

We investigated the impact of relative marital power on 72 newlywed couples’ endocrinological responses to marital conflict. Marital power was determined by comparing spouses’ reports of dependent love for one another. Less powerful spouses displayed elevated adrenocorticotropic hormone (ACTH) responses to a conflict discussion. Shared power appeared to have a beneficial effect on wives’ but not husbands’ ACTH responses. Spouses’ cortisol levels declined over time, except for wives who were less powerful and for husbands who shared power with their wives. Conflict behaviors did not differ as a function of this marital power index. These data suggest that relative levels of general emotional power in relationships may play an important role in spouses’ physiological responses to marital conflict.     

THE COLLEGE SPORTS REFORM MOVEMENT: Reframing the "Edutainment" Industry

Evidence abounds that college sports are rife with corruption. Over a century of reform efforts have failed to bring about lasting structural and cultural changes. Drawing on interview, participant observation, and archival data, the present study examines the diagnostic and prognostic framing of the contemporary college sports reform movement. The faculty-driven wing of the social movement has identified several problems with intercollegiate athletics including (1) commercialization; (2) university involvement in the entertainment industry; (3) damage to the integrity of higher education; (4) exploitation of athletes; and (5) harm to nonathletes. Reform proposals and strategies of The Drake Group and the Coalition on Intercollegiate Athletics are summarized and compared.     

Are We Thinking Straight? The Politics of Straightness in a Lesbian and Gay Social Movement Organization

Daniel Cortese's book, ‘Are we thinking straight: Thepolitics of straightness in a lesbian and gay social movementorganization’ examines the political strategies of theUSA organization, the Straight and Gay Alliance (SAGA), andits efforts to promote ‘safe schools’ for lesbian,gay, bisexual and trans youth (LGBT). The book's main focusis on how SAGA deploys the involvement of ‘straight’or heterosexually-identified individuals as part of SAGA's publicpolitical agenda. As a national organization with numerous localchapters across the United States, SAGA encourages parents,teachers and students to work together to ensure that schoolsactively protect LGBT students from homophobic     

Post-crisis communication and renewal: Expanding the parameters of post-crisis discourse

Crisis communication is growing as a field of study due in part to the frequency and high profile nature of recent crises such as 9/11, Anthrax and bioterrorism in the mail supply, the Tsunami in the Southeast Asia, and Hurricanes Katrina and Rita. In each of these crises, the role of communication has been highlighted. Communication is particularly challenging during crises because an immediate response is necessary, because of the looming threat, and because these situations are inherently uncertain. Much of the present literature suggests that managing image during a crisis is critical to an effective response [Benoit, W. L. (1995). Accounts, excuses and apologies. Albany, NY: State University of New York Press; Coombs, W. T. (1999). Ongoing crisis communication: Planning, managing, and responding. Thousand Oaks, CA: Sage; Hearit, K. M. (1995). “Mistakes were made”: Organizations, apologia and crises of social legitimacy. Communication Studies, 46, 1–17]. Although image is important and embedded within the threat, uncertainty, and chaos of crisis so too is the opportunity for growth and renewal. In this case, depending upon the crisis, either issues of image restoration or renewal may emerge as more of a central theme in the post-crisis discourse. This paper argues that renewal, along with image restoration, is an important genre of post-crisis discourse. As a result, efforts to understand post-crisis communication should be expanded to include both image restoration and the discourse of renewal.     

Modeling Growth and Reduction of Microorganisms in Foods as Functions of Temperature and Time

Food safety objectives (FSOs) are established in order to minimize the risk of foodborne illnesses to consumers, but these have not yet been incorporated into regulatory policy. An FSO states the maximum frequency and/or concentration of a microbiological hazard in a food at the time of consumption that provides an acceptable level of protection to the public and leads to a performance criterion for industry. However, in order to be implemented as a regulation, this criterion has to be achievable by the affected industry. In order to determine an FSO, the steps to produce and store that food need to be known, especially where they have an impact on contamination, growth, and destruction. This article uses existing models for growth of Listeria monocytogenes in conjunction with calculations of FSOs to approximate the outcome of more than one introduction of the foodborne organism throughout the food-processing path from the farm to the consumer. Most models for the growth and reduction of foodborne illnesses are logarithmic in nature, which fits the nature of the growth of microorganisms, spanning many orders of magnitude. However, these logarithmic models are normally limited to a single introduction step and a single reduction step. The model presented as part of this research addresses more than one introduction of food contamination, each of which can be separated by a substantial amount of time. The advantage of treating the problem this way is the accommodation of multiple introductions of foodborne pathogens over a range of time durations and conditions.
