The effect of number of siblings on adult mortality: Evidence from Swedish registers for cohorts born between 1938 and 1972

Demographic research has paid much attention to the impact of childhood conditions on adult mortality. We focus on one of the key aspects of early life conditions, sibling group size, and examine the causal effect of growing up in a large family on mortality. While previous studies have focused on low- or middle-income countries, we examine whether growing up in a large family is a disadvantage in Sweden, a context where most parents have adequate resources, which are complemented by a generous welfare state. We used Swedish register data and frailty models, examining all-cause and cause-specific mortality between the ages of 40 and 74 for the 1938–72 cohorts, and also a quasi-experimental approach that exploited multiple births as a source of exogenous variation in the number of siblings. Overall our results do not indicate that growing up in a large family has a detrimental effect on longevity in Sweden.     

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.     

Is multidimensional treatment foster care (MTFC) more effective than treatment as usual in a three-year follow-up? Results from MTFC in a Swedish setting

This study examines three-year post-baseline outcomes for a randomized controlled trial of Swedish antisocial youths who received either multidimensional treatment foster care (MTFC) or treatment as usual (TAU). Several studies in our literature review indicated that MTFC intervention is preferred to the alternative (TAU) in the USA during follow-up. Two studies (one conducted in the UK and one in Sweden) have shown indications of a washout effect between the intervention alternatives during follow-up. However, this study showed few but positive significant outcomes at follow-up for the MTFC programme in comparison to TAU. Juveniles who participated in MTFC spent fewer days in locked settings and had committed fewer violent crimes, according to the social case records. Two key features of the MTFC programme certainly merit use in general social service—namely, reducing exposure to deviant peers and increasing school participation.     

Development and Evaluation of a Web-Based Clinician Training Program for a Family-Focused Depression Preventive Intervention

This study evaluated the acceptability, feasibility, and satisfaction associated with a newly developed online clinician training program for the Family Talk preventive intervention, both alone and together with a redesigned, shortened, face-to-face component. Fifty-eight predominately in-home therapy clinicians participated in the study. Results indicated that clinician participants found the online training to be enjoyable and comprehensive, and they reported that the most beneficial training package involved the combination of web-based and in-person training. This combined training could efficiently cover necessary didactic material online while also delivering important clinical skill practice and in-person discussion. Exceptions, limitations, and important future research questions are discussed.     

Don't End Up in the Fields: Identity Construction among Mexican Adolescent Immigrants,their Parents,and Sociocontextual Processes

This grounded theory study of 16 Mexican immigrant adolescents and 20 of their parents examines how they construct relational identities within their families, at school, with friends, and in the larger society. Results focus on a core identity bind faced by the adolescents: immigration messages from parents that say, “don't be like me” and the societal message, “you're not like us.” Response to this bind was guided by two contrasting sets of identity narratives: Empowering narratives invited an intentional approach to school and life choices. Restricting narratives maintained an ambivalent approach to school and life choices. Resolution of the identity bind was a collective, ongoing process that has implications for Mexican immigrant families and the professionals who work with them.     

Conflict or consensus: An investigation of stakeholder concerns during the participation process of major infrastructure and construction projects in Hong Kong

Public participation in the planning and design of major public infrastructure and construction (PIC) projects is crucial to their success, as the interests of different stakeholders can be systematically captured and built into the finalised scheme. However, public participation may not always yield a mutually acceptable solution, especially when the interests of stakeholders are diverse and conflicting. Confrontations and disputes can arise unless the concerns or needs of the community are carefully analysed and addressed. The aim of the paper is to propose a systematic method of analysing stakeholder concerns relating to PIC projects by examining the degree of consensus and/or conflict involved. The results of a questionnaire survey and a series of interviews with different entities are provided, which indicate the existence of a significant divergence of views among stakeholder groups and that conflicts arise when there is a mismatch between peoples’ perception concerning money and happiness on the one hand and development and damages on the other. Policy and decision-makers should strive to resolve at least the majority of conflicts that arise throughout the lifecycle of major PIC projects so as to maximise their chance of success.     

Exploring the Link Between Caregiver Affect and Adolescent Sexual Behavior: Does Neighborhood Disadvantage Matter?

In a sample of urban youth (N = 1,070), we examined the links between primary caregiver affect (i.e., warmth and hostility) and two measures of sexual behavior in adolescence - early sexual initiation and sex with multiple partners. We also examined the extent to which neighborhood disadvantage moderated associations between caregiver affect and adolescent sexual behavior. We found that caregiver hostility was positively associated with early sex and sex with multiple partners in neighborhoods characterized by high levels of disadvantage, but inversely associated with both sex outcomes in neighborhoods characterized by low levels of disadvantage. Caregiver warmth, on the other hand, was inversely associated with early sexual initiation and sex with multiple partners in all neighborhoods regardless of neighborhood disadvantage.
