Core Self‐Evaluations,Work–Family Conflict,and Burnout

This study investigated how core self‐evaluations relate to work–family (and family–work) conflict and burnout. Drawing from a sample of 289 police officers and civilian staff who were either married or living in a union as common‐law partners, this study advances an empirical integration of work–family and core self‐evaluations research. The results suggested that even when work, nonwork, and demographic variables are controlled for, positive core self‐evaluations (i.e., composite scale, self‐esteem, locus of control, emotional stability) are related to less work–family (and family–work) conflict. The associations between core self‐evaluations and burnout are partially mediated by work–family (and family–work) conflict. Finally, core self‐evaluations moderated the association between work–family conflict and burnout, but not the one between family–work conflict and burnout.     

SOCIOLOGY AND THE CRISIS OF THE PRESENT (2007 PRESIDENTIAL ADDRESS)

This essay attempts to take a broad view of the historical forces that have shaped the discipline of sociology and continue to shape it. It is organized around the concept of crisis, arguing that sociology has been produced by crises and that it has been defined by its responses to crises. It identifies an ethic of control and manipulation as a chief product of 19th century responses. It suggests that we have once again entered a period of disruption and rapid change, and that the current challenge of sociology is to situate ourselves, reflexively, within a dense web of philosophical, psychological, social, biological, and environmental linkages, recognizing that we can never see the network in its entirety because we ourselves are nodes within it. However, the ethic of control and manipulation that we have inherited from earlier sociological responses often prevents sociologists from developing an immanent, reflexive, and ecological approach to the crisis of the present that would enable us to place ourselves within this web.     

Using Peer Educators for a Classroom-Based AIDS Program

Abstract

In view of recent prevalence and other data regarding alcohol use by college students this article considers whether or not alcohol represents a problem or a changeable problem for these students and/or their colleges. On the one hand, drinking is deeply embedded in the traditions of college life; it does serve some beneficial purposes; and it is often regarded as an accepted, if not expected, part of adolescence. Furthermore, drinking behavior in college is a poor predictor of eventual alcoholism. On the other hand, both difficulty in identifying problem drinking and ambivalence over false positive diagnoses have contributed to a preoccupation with alcoholism, and a denial of subclinical or preclinical but nonetheless real problems. New ways of defining what constitutes an “alcohol” problem, as well as ways of remedying and preventing the problem are discussed. College health personnel are needed to continue their traditional diagnostic and referral functions, but must expand their roles to include involvement with other disciplines in proactive preventive and educational programming.     

On the distribution of products of independent beta variates

This paper concerns an inquiry into the problem of generating closed form expressions for the cumulative distribution and probability density functions of products of independent beta variates. Recursive analytical procedures for constructing the equational forms of these functions-from their Mellin inversion integral representations, via the Cauchy residue theorem-are described. A numerical example illustrating details of the construction of a computable form of the distribution function of the product of three independent beta variates is also included.     

Compassionate Values and Presidential Politics: Mortality Salience, Compassionate Values, and Support for Barack Obama and John McCain in the 2008 Presidential Election

In line with terror management theory, this research demonstrates that mortality salience motivated increased support for John McCain in the absence of reminders of compassionate values. However, polls had indicated that Barack Obama was generally perceived as the more compassionate of the two candidates. Thus, when compassionate values were made salient, death reminders motivated participants to uphold these values by significantly increasing their support for the more compassionate Barack Obama instead. The implications of these findings for terror management theory, the 2008 presidential election, and political endorsements are discussed .     

MATCHED PAIRS DISCRIMINATION: METHODOLOGY AND AN INVESTIGATION OF CORPORATE ACCOUNTING POLICIES

The matched-pairs methodology is becoming increasingly popular as a means of controlling extraneous factors in business research. This paper develops discriminant procedures for matched data and examines the properties of these methods. Data from a recent study by Hunt [14] on the determinants of inventory method choice are used to contrast the performance of the different methods. While all of the methods yield the same set of discriminating variables, those procedures that allow for the dependence among observations within a pair provide greater classificatory power than traditional multivariate techniques.     

Ex Ante and Ex Post Values for Changes in Risks

In this paper, I take risk to mean a composite of the probability of an adverse event and the severity of the consequences of the event. I explore two issues in the economic valuation of changes in individual risks brought about by public policies. These are: (1) the relationship between the values of risk prevention (i.e., the lowering of the probabilities of adverse events) and risk reduction (i.e., the reduction of the severity of the consequences of adverse events); and (2) the relationship between ex ante and ex post measures of the value of changes in risk.     

Robustness estimators of location:a classification of linear and adaptive estimators

Real-world data sets may be described in terms similar to trauma cases- 'messy' with 'high morbidity'. Alternative estimators to the traditional mean are examined via a simulation study over a wide range of both symmetric and asymmetric distributions. These alternative estimators are data depenmdent and, in most cases, represent data far better than the usual mean. Princeton and post-Princeton linear and adaptive estimators of location are summarized, and a classification scheme based on an ancillary or selector statistic is proposed. The computational formulae for the collection of estimators have been standardized, as have the ancillary statistics. We classify these estimators by their computational form, give the computational formulae for each in a standardized notation, evaluate the subclass of estimators, and identify our 'winner' in that class.     

Robust Two-Sample Statistics for Testing Equality of Means: a Simulation Study

When testing the equality of the means from two independent normally distributed populations given that the variances of the two populations are unknown but assumed equal, the classical two-sample t-test is recommended. If the underlying population distributions are normal with unequal and unknown variances, either Welch's t-statistic or Satterthwaite's Approximate F-test is suggested. However, Welch's procedure is non-robust under most non-normal distributions. There is a variable tolerance level around the strict assumptions of data independence, homogeneity of variances and normality of the distributions. Few textbooks offer alternatives when one or more of the underlying assumptions are not defensible.
