Perpetrator or Victim? Relationships Between Intimate Partner Violence and Well‐Being

In national surveys, around half of intimate partner violence perpetrators are also victims of partner assaults. However, data on intimate partner violence victimization and perpetration are rarely examined together. This study examines the relationships between perpetration, victimization, and three psychosocial variables—depression, self‐esteem, and substance abuse—that have been constructed in prior research as both causes and consequences of partner violence. Results indicate that associations between substance abuse and self‐esteem and partner violence perpetration are mediated by controlling for victimization, but depression is associated with both victimization and perpetration. Associations between mutual violence and depression and substance abuse are greater among women than men, supporting the position that gender symmetry in reported violence perpetration does not imply symmetry in outcomes.     

Annual and seasonal habitat use of Columbian black-tailed deer in urban Vancouver, Washington

We investigated habitat use of Columbian black-tailed deer in urban Vancouver, Clark County, Washington, at 3 spatial scales: (1) placement of the annual home range within the landscape mosaic, (2) annual and seasonal locations of deer within the annual home range, and (3) short-term use of critical habitats (fawning areas) within seasonal ranges. Annual home range sizes of deer were 162 ha (SD = 133; 95% minimum convex polygon; MCP) and 266 ha (SD = 228; 95% adaptive kernel; AK) for does, and 756 ha (SD = 290; MCP) and 1,235 ha (SD = 382; AK) for bucks. Home range composition of does did not differ from the study area; home ranges of bucks contained more Natural ecological land-use cover types (ELUs) than did the study area. Within home ranges, both does and bucks used Natural ELUs more often than expected by their occurrence in the home range, both annually and seasonally. During the fawning season, does were also found in Natural ELUs more often than expected. Clark County-designated habitat corridors differed from both the study area and deer home ranges in habitat composition, primarily by containing more Natural and other undeveloped ELUs. Deer were located in habitat corridors more than expected. Deer in urban areas appear to use undeveloped habitat types for security. Management that maintains Natural ELUs, such as establishment of wildlife corridors, can provide important habitat components for black-tailed deer in urban habitats.     

Generalized discriminant analysis based on distances

This paper describes a method of generalized discriminant analysis based on a dissimilarity matrix to test for differences in a priori groups of multivariate observations. Use of classical multidimensional scaling produces a low‐dimensional representation of the data for which Euclidean distances approximate the original dissimilarities. The resulting scores are then analysed using discriminant analysis, giving tests based on the canonical correlations. The asymptotic distributions of these statistics under permutations of the observations are shown to be invariant to changes in the distributions of the original variables, unlike the distributions of the multi‐response permutation test statistics which have been considered by other workers for testing differences among groups. This canonical method is applied to multivariate fish assemblage data, with Monte Carlo simulations to make power comparisons and to compare theoretical results and empirical distributions. The paper proposes classification based on distances. Error rates are estimated using cross‐validation.     

DETECTING NATURAL SELECTION: THE STEPWISE MUTATION MODEL WITH HETEROSIS

The problem of testing whether heterozygotes have a selective advantage is considered, assuming the stepwise mutation model for electrophoretic alleles. The population is observed for a number of generations, and the likelihoods of the changes in allele frequencies under the heterozygote advantage model and under the strict neutrality model are compared. It is shown by simulation that statistical tests based on the likelihoods have little power to detect selection if only a few generations of data are available.
Many population genetic models, including the stepwise mutation model, have been formulated as diffusion processes in continuous time. The paper gives expressions for the likelihoods of multivariate diffusions observed over a time interval.     

Tropophilia: A Study of People,Place and Lifestyle Travel

This paper explores the changing relations between people and place that are set in motion through mobility. Examining the mobilities of lifestyle travellers, it argues that new relations are sought by this group that undermines traditional assumptions of stability and preservation in the person–place relation. In their stead, lifestyle travellers seek dynamism, change and instability in their engagements with place. This situation suggests that the traditional recognition of the need for a rooted, static and stable set of relations with place – i.e. topophilia – can be supplemented by the love of mobility, change and transformation in the person–place relation – coined tropophilia. The paper raises the important point that a desired connection between ‘people’on one hand and ‘place’ on the other may only occur when their respective paces and trajectories positively coincide.     

Requirements, Risks, and Responsibility: Mothering and Fathering in Books about Raising Boys

The last two decades have been marked by increased attention from scholars, policy makers, and the mass media to girls' needs and experiences. More recently, two developments have contributed to a gender focus that puts boys at the center of popular and academic discourse: recent school shootings and reactions to the research focusing on girls. As one of many attempts at refocusing academic and policy discourse on boys, a genre of books about raising boys has emerged. This study discusses three popular books on the gender ideologies of parenting, by Gurian (1997), Pollack (1998), and Kindlon and Thompson (1999). We find that the three books hold mothers to higher expectations and to more elaborate requirements than they hold fathers. The claimed risks to sons associated with mothers assume an overabundance of qualities that these authors argue mothers are expected to possess in moderate proportions. Moreover, women's internal/biological processes, such as temperament, are more likely to be blamed for bad mothering, while external/environmental processes tend to be blamed for bad fathering. This examination has implications for policy decisions, research fund allocations, the reconstitution of essentialist and patriarchal expectations held by the lay public, the scholarly work on mother-blame, and the academic discourse on gender development.     

Education and Social Policy in Central Asia: The Next Stage of the Transition

This paper discusses the challenges facing the education system of Central Asia and evaluates how these have been addressed in the market economy. We first review the evidence on the economic return to education and determine how the rewards to different levels of education changed during the transition. We then examine the trends in school enrolment and evaluate whether changes in supply or demand explain the enrolment trends we observe. Finally, we evaluate the efficiency of the delivery of education and whether market forces have improved the management of schools. We conclude with a summary of the economic and policy lessons derived thus far from the educational transition. The paper uses aggregate administrative data supplemented with survey data, primarily from the Kyrgyz Republic and Kazakhstan, on enrolment, completion, and expenditures.     

Characteristics of Women With Children Who Divorce in Midlife Compared to Those Who Remain Married

This study evaluated characteristics that distinguish women who end a first marriage in midlife from those who remain married. The sample consisted of 459 married and 180 divorced women who had participated in 3 waves of the National Survey of Families and Households (NSFH). Discriminant analyses were used to assess differences that occurred between the two groups in financial and psychological well-being in the 10 years between NSFH Waves 2 and 3. The major finding was that midlife divorce appears to have long-term financial consequences for women, especially in regard to wealth accumulation. The findings provide some initial information about the long-term effects of midlife divorce that will be useful to professionals working with women who are considering divorce at this stage of life.
