Adaptation to Cesarean Birth: Implementation of an International Multisite Study

The purpose of this column is to describe the implementation of an international multisite Roy adaptation model-based study of women’s perceptions of and responses to cesarean birth. The need for the study arose from the concern that women’s childbearing needs may not be met to their full satisfaction, especially if the infant is born by cesarean. Serendipity and networking played a part in the selection of four study sites in the United States (Boston, Milwaukee, Norfolk, Oklahoma City) and two in other countries (Finland, Australia). Data were collected by nursing students and staff nurses. Post-hoc consideration of the diversity of study sites revealed opportunities for examination of the influence of the contextual stimuli of culture and geographic region on the women’s adaptation to cesarean birth. Strategies used to foster integration of teaching, practice, and research are discussed

Skewed sex ratios in a newly established osprey population

With recent increases in the numbers of reintroduction projects, it has become crucial to know the main factors that allow colonization of new areas and prevent the extinction of small and reintroduced populations. Dispersal is one of the most important phenomena in population biology with consequences to the proportion of individuals that keep breeding in the natal population and the number of individuals that move to other populations to breed. We studied changes in offspring sex ratio and differences in dispersal patterns between the sexes in a reintroduced population of osprey (Pandion haliaetus). Results showed that at the beginning of the colonization process breeding pairs produced more males, which dispersed shorter distances and were more philopatric than females. However, with increasing breeding population size over the years, the offspring production was skewed to females, which dispersed longer distances from their natal area and tended to breed in different areas. Here we suggest that changes in offspring sex ratio during colonization processes, together with differences in dispersal pattern between sexes, could influence colonization rate and the probability of success of future reintroduction projects

The Effects of Stereotypical Cues on the Social Categorization and Judgment of Ambiguous-race Targets

The current study was conducted to test the hypotheses that categorization and subsequent judgments of ambiguous-race targets would be affected by contextual stereotypical cues, and moderated by personality traits of the perceiver. Participants viewed a social networking profile of an ambiguous-race individual with Black, White, or neutral stereotypical information presented in a between-subjects design. In accordance with hypotheses, results indicated that the ambiguous-race targets were categorized congruently with the stereotypical information. Additionally, several of the subsequent judgments about the target’s traits differed as a function of this stereotypic information as well as personality traits of the perceiver, such as prejudice level and authoritarianism. Furthermore, ambiguous-race targets were judged less positively overall and more negatively on work-related traits by individuals high in social dominance and authoritarianism. Implications regarding the social categorization literature along with ramifications for multiracial individuals in the real world are discussed

Mixed-Mode Surveys Compared with Single Mode Surveys: Trends in Responses and Methods to Improve Completion

This article reviews recent trends in modes of conducting surveys and presents results from a series of experiments comparing different approaches for collecting survey data and improving response rates in general population studies. The modes examined include the telephone, mail, and a mixed-mode method which combines mail with Web data collection. A series of studies were conducted by the Oregon State University Survey Research Center from 2006-2014 using probability samples of Oregon residents. Response rates and the percent of respondents completing the questionnaires by Web were compared. The results showed that response rates were increased by modifying the cover letter to emphasize the cost savings of an online response, adding a fifth contact, and limiting instructions for respondents. A mixed-mode approach, providing only a Web link, resulted in more respondents replying by Web as compared with individuals given an option of completing the questionnaire by Web or mail. The demographics of the respondents, as compared with the general population, varied across each mode

Using manipulation of density-dependent fecundity to recover an endangered species: the bearded vulture Gypaetus barbatus as an example

1. Endangered species subjected to reintroduction programmes often occur as small and isolated populations with local high density and depressed fecundity. Variation in territory quality may lead to this low fecundity owing to increasing occupation of suboptimal territories as population density grows, known as the habitat heterogeneity hypothesis (HHH). In this context, food supplementation in poor territories may be used to produce extra young which could be allocated to reintroduction programmes. 2. We analyse the density-dependent fecundity pattern and the underlying mechanism in a small population of bearded vultures Gypaetus barbatus in Aragón (northeast Spain). We then use population simulations to examine the viability of a hypothetical reintroduction programme using extra young produced by supplementary feeding on poor-quality territories and the effect on the donor population. We also compare the economic cost of such a reintroduction programme in relation to the cost of a traditional captive breeding programme. 3. The wild population showed clear negative, density-dependent fecundity regulation driven by the HHH mechanism. Simulations showed that extractions for translocations had no relevant long-term effects on the donor population viability, but a marked population reduction during the extraction period. However, the implementation of supplementary feeding to produce extra young for translocation lessened significantly this expected initial population reduction. 4. Analyses showed that the annual budget of a captive breeding programme for this species could be seven times more expensive than the translocation of extra young produced by food supplementation. 5. Synthesis and applications. Reintroduction programmes based on translocation of wild-reared individuals, after a supplementary feeding programme oriented to poor-quality territories, provide a source of young at least seven times cheaper than those from captive breeding programmes. The use of this approach would decrease initial effects on donor population avoiding public criticism. Increasing the number of young released during the first years of the reintroduction decreases total financial cost and increases the final population size in the new area

Women’s Perceptions of Caesarean Birth: A Roy International Study

The purpose of this Roy adaptation model-based multi-site international mixed method study was to examine the relations of type of caesarean birth (unplanned/planned), number of caesarean births (primary/repeat), and preparation for caesarean birth to women’s perceptions of and responses to caesarean birth. The sample included 488 women from the United States (n = 253), Finland (n = 213), and Australia (n = 22). Path analysis revealed direct effects for type of and preparation for caesarean birth on responses to caesarean birth, and an indirect effect for preparation on responses to caesarean birth through perception of birth the experience

The role of age of first breeding in modeling raptor reintroductions

1. The present biodiversity crisis has led to an increasing number of reintroduction programs, and this conservation method is likely to be increasingly used in the future, especially in the face of climate change. Many fundamental questions in population ecology are focused on the mechanisms through which populations escape extinction. 2. Population viability analysis (PVA) is the most common procedure for analyzing extinction risk. In the use of PVA to model the trajectories of reintroduced populations, demographic values are sometimes taken from other existing wild populations or even from individuals in captivity. 3. Density dependence in productivity is usually considered in viability models, but density‐dependent variation in age of first breeding is usually ignored. Nevertheless, age of first breeding has a buffering effect on population fluctuations and in consequence on population persistence. 4. We simulated the viability of Spanish Imperial Eagle (Aquila adalberti) and Osprey (Pandion haliaetus) populations using data from established and reintroduced populations in southern Spain. 5. Our results show that reduction in the age of first breeding is critical in the success of reintroductions of such long‐lived birds. Additionally, increases in productivity allow populations to growth at maximum rate. However, without considering variation in age of breeding, and the associated increasing overall productivity, reintroduced populations seem nonviable. 6. To ignore density dependence in age of breeding in PVA means that we are seriously limiting the potential of the model population to respond to fluctuations in density, thereby reducing its resilience and viability. Variation in age of first breeding is an important factor that must be considered and included in any simulation model involving long‐lived birds with deferred maturity

Financial Well-Being and Postdeployment Adjustment Among Iraq and Afghanistan War Veterans

Research has yet to examine the relationship between financial well-being and community reintegration of veterans. To address this, we analyzed data from n=1,388 Iraq and Afghanistan War Era Veterans who completed a national survey on post-deployment adjustment. The results indicated that probable major depressive disorder, posttraumatic stress disorder, and traumatic brain injury were associated with financial difficulties. However, regardless of diagnosis, veterans who reported having money to cover basic needs were significantly less likely to have post-deployment adjustment problems such as criminal arrest, homelessness, substance abuse, suicidal behavior, and aggression. Statistical analyses also indicated that poor money management (e.g. incurring significant debt or writing bad checks) was related to maladjustment, even among veterans at higher income levels. Given these findings, efforts aimed at enhancing financial literacy and promoting meaningful employment may have promise to enhance outcomes and improve quality of life among returning veterans

Self-report and Longitudinal Predictors of Violence in Iraq and Afghanistan War Era Veterans

This study, using a longitudinal design, attempted to identify whether self-reported problems with violence were empirically associated with future violent behavior among Iraq and Afghanistan war veterans and whether and how collateral informant interviews enhanced the risk assessment process. Data were gathered from N = 300 participants (n = 150 dyads of Iraq and Afghanistan war veterans and family/friends). The veterans completed baseline and follow-up interviews 3 years later on average, and family/friends provided collateral data on dependent measures at follow-up. Analyses showed that aggression toward others at follow-up was associated with younger age, posttraumatic stress disorder, combat exposure, and a history of having witnessed parental violence growing up. Self-reported problems controlling violence at baseline had robust statistical power in predicting aggression toward others at follow-up. Collateral report enhanced detection of dependent variables: 20% of cases positive for violence toward others would have been missed relying only on self-report. The results identify a subset of Iraq and Afghanistan war veterans at higher risk for problematic postdeployment adjustment and indicate that the veterans' self-report of violence was useful in predicting future aggression. Underreporting of violence was not evidenced by most veterans but could be improved upon by obtaining collateral information
