Demographic differences in response rates for PHQ9 in a university student population

Objective: To examine differences in complete response rates for depression screening questions based on demographic characteristics. Methods: Cross-sectional study examining associations between demographic characteristics and completely responding depression-screening questions. Participants: “Healthy Minds Study” data, collected in a public University in February 2016, where 7,326 students participated. Results: women (AOR: 0.69; 95% CI =0.57–0.83) and gay/lesbian students (AOR: 0.24; 95% CI =0.10–0.60) had better complete response rates. Non-US (AOR: 1.46; 95% CI =1.03–2.07), black (AOR: 3.32; 95% CI =1.92–5.77), and Middle-Eastern students (AOR: 3.73; 95% CI =1.73–8.02) had lower complete response rates. Conclusions: Our study shows sex, gender, citizenship, and race categories have significant differences in complete response rates for the outcome. Our findings have several implications; including recognizing interventions for depression based on responders may not target those that tend to be “partial-responders”. Efforts in survey design, recruiting and completion of surveys should be maximized.     

Precopulatory Sexual Cannibalism and Other Accidents: Evolution,Material Trans Theory,and Natural Law

Natural law perspectives take existing formations of life-matter and translate them into normative templates. From an evolutionary perspective, the normative aspect of natural law is always under suspicion. Because life-forms have histories and futures that are shaped by a dynamic of accidents, they are not susceptible to normative assertions about what they “should” be or do. This is particularly the case with sex. Sexual reproduction is a minoritarian strategy within the full spectrum of life. Like all aspects of life, sex is a product of a fluctuating backdrop of phylogenetic (species-forming) and ontogenetic (individual-forming) accidents. And like all aspects of life, it continues to vary within this field of material processes. My argument in this essay is that, rather than a fully integrated feature of a lawlike apparatus, sex is a mess. From the evolutionary perspective—and especially, I show, in the light of the new “extended evolutionary synthesis”—sex always has been and always will be barnacled with accidents. This dovetails with what we might call material trans theory, a species of New Materialism that sees sex as a concrescence of material forces and processes introjected into bodies. Both views leave sex fundamentally incompatible with metaphysical explanations or metaphysical norms—including and especially natural law.     

Avian haemosporidian parasites in an urban forest and their relationship to bird size and abundance

Urbanization has been identified as a threat to biodiversity due to landscape modifications. Studies of parasite ecology in urbanized areas lagged behind those made on macro organisms. Here we studied infection prevalence of haemosporidian parasites in an avian community of an urban forest from Germany, and its relationship with bird abundance and body mass. We used PCR to amplify a fragment of the mtDNA cyt b gene to determine the infection status of birds, and bird point counts to determine bird relative abundances. The avifauna was dominated by two small sized insectivore passerines (Parus major, Cyanistes caeruleus), representing ~40 % of the total bird records. The highest haemosporidian prevalence was recorded for Turdus philomelos (100 %) and for Fringilla coelebs (75 %). Bird abundance and body mass were positively associated with infection status for two haemosporidian genera: Plasmodium and Leucocytozoon. Infection rate was lower in juveniles compared to adult birds. We recorded a total of 7 Plasmodium, 26 Haemoproteus, and 10 Leucocytozoon lineages. Avian malaria (P. relictum) was detected infecting 5 individuals of P. major, the most abundant species in the community. These results, together with those of previous studies at the same site, suggest that potentially any of the genetic haemosporidian lineages detected in this urban forest can be transmitted across native and pet bird species, and to species of conservation concern housed at aviaries.     

Child sexual abuse and psychological impairment in victims: results of an online study initiated by victims

Sexual abuse of children has been a topic of scientific investigation for the past few decades. Research in this area, however, is rarely initiated, conceptualized, and conducted by victims themselves. Apart from possibly having painted a one-sided picture of sexual abuse, this presumed dominance of nonvictims might also have marginalized victims in a research area central to their lives. This study was conducted by a victims interest group as an effort to meet the need to add victims' perspectives to our current understanding of this topic. The online survey focused on investigating victims' psychosocial impairment, which was found to be extensive. Results indicated that an intact social support system facilitates better health, especially when offered early on.     

A Conversation With Virus X: Outing a Malevolent and Subversive Force in Parents' Lives

The following conversation describes a narrative means of uncovering (or ‘deconstructing’) some of the invisible forces that undermine parents' capacities in caring for their children in preferred ways. In the authors' experience, parents can be hugely resourceful and provide a clear account of what they ‘should’ be doing, yet seem unable to act upon their own good advice — it is as though an external agent, named below as ‘Virus X’, prevents them from being the parents they would like to be. Through naming this external agent, identifying its influences and noticing parents' acts of resistance in the face of these influences, antidotes to Virus X can be developed. This paper describes the development of such an approach within a child behaviour management group. In keeping with the playful approach encouraged by narrative therapy, the authors of this paper join forces to act as investigative journalists in exposing Virus X to the readers.     

Native American Food Security and Traditional Foods: A Review of the Literature

This piece explores the emergent themes and subthemes represented within the recent contemporary discourse on Native American food security. Analysis revealed traditional foods as the most common theme present within the sampled literature. We offer a review of this theme (and related subthemes such as food access and human and environmental health) to illuminate the primary concerns, opportunities, preferences, and barriers associated with Native American food security. Our assessments also provide a nuanced understanding of existing literature related to food security and sovereignty, as well as key dimensions of environmental and social equality.     

Bullying: Three Books Delve Behind the Statistics

SUMMARY

Seventy percent of students are bullied in school, many of them because they are, or are perceived to be, lesbian, gay, bisexual, or transgender. Bullying and victimization are not just part of growing up. They have long-term negative consequences for bullies and victims alike. Three recent books shed light on the issues.     

Resource characteristics in social exchange networks: Implications for positional advantage

Despite the wide range of resources that traverse social networks, social exchange research has focused on only a narrow subset. Notably, prior social exchange research has not considered resources like information that have the capacity to diffuse through networks. The current study investigates how differences between the standard social exchange resource and an information-type resource affect the advantage provided by one's network position. Results of a laboratory experiment support predictions and offer two new insights to the foundations of positional advantage: (1) the location of advantageous positions in a network differs by resource characteristics, and (2) only in particular situations is a single position able to experience high levels of both power and exchange frequency.     

Votes,Favors, Toys,and Ideas: The Effect of Resource Characteristics on Power in Exchange Networks

Abstract

The goal of this research is to understand how resource characteristics influence the development of power in exchange networks. Transferability and duplicability are identified as fundamental resource characteristics that have not been examined systematically in prior social exchange research. Varying resource transferability and duplicability alters the mechanisms that produce power and determine which positions in a network have a power advantage. To predict where power will develop, I rely on existing measures for previously studied resources and introduce relevant principles of network structure for resources that have not been studied before. This theoretical logic is supported by a series of simulated exchange networks that apply behavioral principles observed in prior experimental research to the exchange of a broader variety of resources than previously considered. Results indicate how the pattern of power use in a network is contingent upon the type of resource being exchanged.
