Influence of behavioural tactics on recruitment and reproductive trajectory in the kittiwake

Many studies have provided evidence that, in birds, inexperienced breeders have a lower probability of breeding successfully. This is often explained by lack of skills and knowledge, and sometimes late laying dates in the first breeding attempt. There is growing evidence that in many species with deferred reproduction, some prebreeders attend breeding places, acquire territories and form pairs. Several behavioural tactics assumed to be associated with territory acquisition have been described in different species. These tactics may influence the probability of recruiting in the breeding segment of the population, age of first breeding, and reproductive success in the first breeding attempt. Here we addressed the influence of behaviour ('squatting') during the prebreeding period on demographic parameters (survival and recruitment probability) in a long-lived colonial seabird species: the kittiwake. We also investigated the influence of behaviour on reproductive trajectory. Squatters have a higher survival and recruitment probability, and a higher probability of breeding successfully in the first breeding attempt in all age-classes where this category is represented. The influence of behaviour is mainly expressed in the first reproduction. However, there is a relationship between breeding success in the first occasion and subsequent occasions. The influence of breeding success in the first breeding attempt on the rest of the trajectory may indirectly reflect the influence of behaviour on breeding success in the first occasion. The shape of the reproductive trajectory is influenced by behaviour and age of first breeding. There is substantial individual variation from the mean reproductive trajectory, which is accounted for by heterogeneity in performance among individuals in the first attempt, but there is no evidence of individual heterogeneity in the rate of change over time in performance in subsequent breeding occasions

“A rape was reported”: construction of crime in a university newspaper

Historically, the news media have engaged in high rates victim blaming in their reporting of sexual assaults. However, in recent years, gains in civil rights and renewed attention to Title IX may mean sexual assault victims are receiving less-biased news coverage. Using a content analysis, we examined the tone and message of all crime stories published in one United States university newspaper from academic year 2015–2016 (n = 99). Comparing attributions of responsibility made to both victims and offenders across several major crime categories (rape, murder, sexual assault, robbery, physical assault, sexual misconduct, and sexual abuse), and consistent with historical trends, we found higher levels of victim blaming in stories on rape and sexual assault than any other crime. We identify rhetorical devices commonly used to discredit the victim and/or absolve the perpetrator. Despite perceived gains achieved by Title IX, news coverage continues to buttress victim blaming culture.     

Coproduction and the third sector in France: Governmental traditions and the French conceptualization of participation

Research on coproduction has tended to assume a coherence of conceptualizations of coproduction across borders, and little analysis of the framing and discourse of coproduction in different contexts has been undertaken. In the French language literature on citizen participation and the social and solidarity economy, the term coproduction is little used. This paper investigates the narratives of French academics, public, and third sector actors in order to identify what, if anything, is different about the French context that explains this gap. Drawing on semistructured interviews, I identify four key narratives that distinguish the French conceptualizations of coproduction and the third sector from the dominant English language coproduction literature: (a) a mainstreaming of coproduction as part of organizational purpose in the social and solidarity economy, (b) an emphasis on formalized involvement of citizens in organizational governance, (c) the motivation of citizen empowerment and democracy over cost and efficiency, and (d) the use of the term coconstruction rather than coproduction. I argue that these narratives are shaped by the governmental traditions of France, which emphasize formal rules, hierarchy, representative democracy, and a suspicion of particularistic interests. I conclude by questioning the universality of some of the axioms of coproduction theory in the English language literature.     

Vacant land conversion to community gardens: influences on generalist arthropod predators and biocontrol services in urban greenspaces

Due to economic decline and the recent rise in home foreclosure, many U.S. cities are faced with managing large acreages of vacant land. Interest in local food production on this land has the potential to dramatically reshape the composition of greenspace found within urban landscapes. This study examined how the conversion of vacant land to urban gardens and farms influenced arthropod generalist predator populations and their ability to support biocontrol services. We found that the abundance of Coccinellidae and Syrphidae, and the activity density of Carabidae, Formicidae, and Lycosidae were equivalent among vacant lot and urban garden sites. Dolichopodidae abundance and the activity density of Linyphiidae and Opiliones were reduced in urban gardens whereas Anthocoridae abundance and the activity density of Staphylinidae were greater within urban gardens relative to vacant lots. The biocontrol service supplied by generalist predators was measured using sentinel eggs (Helicoverpa zea (Noctuiidae)) and pupae (Sarcophaga bullata (Sarcophagidae) and Musca domestica (Muscidae)). We found no difference in the biocontrol of H. zea eggs or M. domestica pupae among the focal greenspaces. We found no difference in the removal of S. bullata pupae by predators in June 2010, whereas in August 2010 a greater proportion of pupae were removed in urban garden sites relative to vacant lots. Based on these findings, we discuss the potential of the urban landscape to support generalist predators and sustainable urban gardening and farming.     

Modeling population and subject-specific growth in a latent trait measured by multiple instruments over time using a hierarchical Bayesian framework

Psychometric growth curve modeling techniques are used to describe a person’s latent ability and how that ability changes over time based on a specific measurement instrument. However, the same instrument cannot always be used over a period of time to measure that latent ability. This is often the case when measuring traits longitudinally in children. Reasons may be that over time some measurement tools that were difficult for young children become too easy as they age resulting in floor effects or ceiling effects or both. We propose a Bayesian hierarchical model for such a scenario. Within the Bayesian model we combine information from multiple instruments used at different age ranges and having different scoring schemes to examine growth in latent ability over time. The model includes between-subject variance and within-subject variance and does not require linking item specific difficulty between the measurement tools. The model’s utility is demonstrated on a study of language ability in children from ages one to ten who are hard of hearing where measurement tool specific growth and subject-specific growth are shown in addition to a group level latent growth curve comparing the hard of hearing children to children with normal hearing.KEYWORDS: Bayesian hierarchical models, psychometric modeling, language ability, growth curve modeling, longitudinal analysis     

Mentoring Matters: An Innovative Approach to Infusing Mentorship in a Social Work Doctoral Program

Social work doctoral students must identify how to prioritize their time and how to gain the many qualifications required by the academic job market. Mentoring has long been recognized as an effective strategy for promoting academic success and degree completion in doctoral studies. This article describes three student-led initiatives in a social work doctoral program that sought to infuse mentorship throughout the program. The content of these innovative initiatives is discussed, as well as their implications for social work doctoral education.     

Will You Die for Your Country? Workplace Death in an Era of Mass Incarceration

People with criminal records in the United States continue to face limited employment opportunities due to social stigma and legal barriers. In contrast to the civilian sector, the military conducts a “whole person” evaluation to screen potential recruits and regularly hires people with felony and misdemeanor records. Moreover, evidence suggests that the military serves as a socially integrative institution and may facilitate desistance from future crimes. However, critics argue that the military exacerbates inequalities by subjecting marginalized communities to the unequal burden of service. Using the data obtained from the Army, we examine the relative risks of combat exposure and casualties between enlisted soldiers with and without criminal records who joined between 2002 and 2009. The results suggest that soldiers with felony and misdemeanor records are more likely to be assigned to combat occupations than those without criminal records. We also find that among soldiers assigned to positions with low combat exposure, ex-offenders face a higher risk of death compared to those without criminal records. Findings do not dispute the idea that the military facilitates desistance from future crimes and provides second chances to people with criminal records, but reaffirm the fact that military service costs lives and limbs.     

Innocent victims,creepy boys: discursive framings of sexuality in online news coverage of the celebrity nude photo hack

Following the hack, theft, and digital dissemination of hundreds of nude celebrity photographs—colloquially referred to as “The Fappening”—in August 2014, online news sites filled with speculation about and commentary upon the actions of both the hackers and the celebrities. Through a critical discourse analysis of coverage of the female celebrities and hackers in six online news outlets this project presents “The Fappening” as a case study for better understanding the ways in which the media produces discourses about sexuality, particularly sexual deviancy and victimhood. The discourse surrounding this incident was inflected with feminist ideals. The celebrities were constructed as victims not only of the hack but of broader structural issues around women’s bodies, while the hackers and posters of the photos were derided as perverted, lonely thieves. Overall, the feminist leanings of the discourse around “The Fappening” indicate that the actions of the celebrities—that is, taking and privately sharing nude photographs—can be integrated into dominant understandings of sexuality, while the online communities that stole and shared their photos must be rejected. However, the coverage indicates that celebrities who use their sexual allure for publicity deserve their victimization, undermining the apparently progressive focus of the discourse.     

Professional quality of life of adult protective service workers

Adult Protective Services (APS) workers are exposed to substantial occupational hazards and job stress, but these stressors are underdocumented. Therefore, we sought to describe APS workers’ work environments and responses to occupational hazards and stressors, including compassion fatigue, burnout, and secondary traumatic stress. Survey data were gathered with closed-ended questionnaires administered to APS workers in an urban setting. Virtually all workers (97%) reported exposure to one or more environmental hazards in their work, and 80% reported hazard exposure in the past month. Workers also reported mixed responses to their work environment and to experiences with supervision. A sizable minority (22.7%) was at high risk for burnout, 24.6% were at risk for secondary traumatic stress, and 19.9% reported low compassion satisfaction. The results document multiple stressors in APS work. The APS partner is committed to ongoing efforts to better support its staff, and these findings can inform future efforts to enhance supervisor support and worker self-care, to minimize burnout and secondary traumatic stress.
