Peer-led interventions to reduce HIV risk of youth: A review

One approach in HIV prevention programming targeting youth is to use peer leaders in what is referred to as peer education programming. This paper critically reviews and synthesizes the results and lessons learned from 24 evaluated peer-led programs with an HIV/AIDS risk reduction component that target youth in the communities where they live and are delivered in low- and middle-income countries. Interventions were identified through a comprehensive search of the peer reviewed AIDS-related literature as well as publication lists of major organizations in the UN family that address HIV and AIDS. Our synthesis of study results finds that these programs have demonstrated success in effecting positive change in knowledge and condom use and have demonstrated some success in changing community attitudes and norms. Effects on other sexual behaviors and STI rates were equivocal. We include an overview of characteristics of successful programs, a review of program limitations, and recommendations for the development and implementation of successful community-based peer-led programs in low-income countries.     

Dividing women: the framing of trafficking for sexual exploitation in magazines

Each year thousands of women are trafficked for sexual exploitation. To understand how the mass media represent trafficking, a qualitative framing analysis of magazines, published from 2000 through to 2010, was conducted. Results showed magazines presented complementary frames of victimization and benevolence. Magazine articles shed light on trafficking, which operates in society’s shadows and is far removed from many people’s lives, but articles reinforce hierarchies and divisions: between women and men; among women; and among “good” prostitutes who deserve help and “bad” prostitutes who do not. Articles imply that the problem of trafficking is one of individual vulnerability, which can be remedied by charitable efforts, and ignore the larger cultural, political, economic, and educational systems of sex discrimination. Traffickers and men who buy sex were largely absent from magazine stories, and focus on the sale of sexual services, rather than the purchase, emphasized women’s role in the trafficking process while making men’s roles invisible. Because the mass media can shape public opinion and public policy, such incomplete reports may lead to ineffective policies.     

Estimators for a Poisson parameter using ranked set sampling

Using ranked set sampling, a viable BLUE estimator is obtained for estimating the mean of a Poisson distribution. Its properties, such as efficiency relative to the ranked set sample mean and to the maximum likelihood estimator, have been calculated for different sample sizes and values of the Poisson parameter. The estimator (termed the normal modified r.s.s. estimator is more efficient than both the ranked set sample mean and the MLE. It is recommended as a reasonable estimator of the Poisson mean ( λ) to be used in a ranked set sampling environment.     

Humanitarianism with a Sovereign Face: UNHCR in the Global Undertow

This article examines the global forces that are responsible for the transformation of the meaning and practice of UNHCR's humanitarianism, and asks whether a transformation that enables the organization to become more deeply involved in the internal affairs of states is welcome or worrisome. I open by reviewing the changing relationship between multilateralism, sovereignty, and humanitarianism, and link that conceptual discussion to the international refugee regime. I then argue that the combination of state pressures and the normative principle of popular sovereignty enabled a more political and pragmatic UNHCR to widen its activities under the humanitarian banner and to become more deeply involved in the circumstances in the refugee‐producing country. This expanding humanitarian umbrella, I suggest, might be a stealth agent for a policy of containment and a threat to refugee rights. This possibility is suggested by recent debates over the category of internally displaced peoples; the decided preference for repatriation; and UNHCR's involvement in reintegration activities. These developments generate the worrisome possibility that a more pragmatic UNHCR is potentially (though unwittingly) implicated in a system of containment. I conclude by reflecting on UNHCR's role in global politics and the dangers of a sovereignty‐led humanitarianism.     

Couples Managing the Risk of Financing Long-Term Care

This study examined the complexity of financial long-term care (LTC) decision outcomes among married couples. Supporting the theory of planned behavior, couples reported a range of consensus patterns with their financial LTC intentions and behaviors. Five newly articulated typologies of couples emerged from consensus patterns revealing that couples reported a range of financial LTC intentions and behaviors. More couples reported consensus with their financial LTC behaviors compared to intentions; financial LTC decision outcomes reflected a dynamic and on-going process; and couples were not always in agreement on their financial LTC decision outcomes. Findings reinforce the importance of family practitioners going beyond working with individuals to understanding couple-level planning for financing LTC.     

Canadian Visa Officers and the Social Construction of “Real” Spousal Relationships

Cet article examine l'existence d'un paradoxe de facilitation/contrôle dans le cadre des efforts gouvernementaux de contrôler la migration des époux. La littérature sur le jugement discrétionnaire et les fonctionnaires de proximité est utilisée pour analyser comment les agents canadiens des visas décident quelles relations de couples sont “vraies” ou “fausses”. Cet article démontre que les agents des visas utilisent plusieurs cadres de référence pour construire des modèles types de ce que sont les relations “normales” entre époux. Ces modèles types permettent aux agents des visas de construire des cas comme crédibles ou non crédibles, et ce processus établit les bases des décisions concernant l'exclusion et l'inclusion d'immigrants. This paper questions whether there is a facilitation/enforcement paradox associated with state efforts to control spousal migration. The literature on discretion and street‐level bureaucrats is used to analyze how Canadian visa officers make decisions about which spousal relationships are “real” and which are “fake.” The paper shows that visa officers use various cultural frameworks to construct typifications of “normal” relationships. These typifications allow visa officers to construct cases as credible or not credible, and constitute simultaneous bases for decisions about immigrant exclusion and inclusion.     

Technological newness: An empirical study in the process industries

Technological change in product development is a crucial issue in the management of technology. The entire sweep of technological changes over the past hundred of years is, in essence, the sum of thousands of individual product development projects in thousands of firms. Yet the degree of technological change in individual development projects has not been extensively studied. This paper presents a four-dimensional characterization of technological newness for product development projects in the process industries in which product development is closely tied to process innovation. The characterization uses four dimensions of change that are required in the development of new products: chemistry, production equipment, fabrication technology and process control. Based on the framework of technological newness, the paper presents data collected on the degree of process change in a set of 20 product development projects conducted by a large manufacturer of advanced polymers. The data provide a clear demonstration of the value of the measurement framework, showing a strong relationship between the characterization of change and the project performance.     

Personal Network Characteristics as Predictors of Change in Obesity Risk Behaviors in Early Adolescence

The potential for peers to influence obesity risk behavior increases in adolescence, yet there are knowledge gaps of how behaviors are modified in response to peers over time. This study examined how personal friendship network characteristics were associated with obesity‐related behaviors from late childhood to early adolescence. Two waves of friendship, physical activity, screen time, and dietary recall data were collected from 11‐ to 13‐year‐old students (99% retention) in Australia (n = 308) over a five‐ to eight‐month period. Regression models identified friendship network characteristics that predicted later health behaviors which varied by gender and behavior type, such as the number of friends positively associated with physical activity intensity (males) and screen time (females). The need for considering context to influence behavior change is discussed.     

All The Same? On a Certain Pattern in Cross-National Death Risk

This article considers whether a nation that fares relatively well (or badly) on a particular dimension of mortality risk tends also to do so on others. Working with 2016 data from the Global Burden of Disease (GBD) Study, we focus on six causes of premature death: transport accidents, other accidents, homicide, early-childhood diseases, and both communicable and noncommunicable diseases beyond early childhood. We consider data from all 26 nations that had populations of at least 50 million in 2016, as well as 15 clusters of smaller nations that are similar in longevity (e.g., Scandinavia). We use an analytic method that facilitates useful comparisons across nations, for it recognizes that some potential death risks can be underestimated because citizens die sooner from other causes. We estimate reductions in lifespan from each of the six causes relative to natural lifespan as defined by GBD. It emerges that, for all 15 pairings among the six causes, these reductions are positively correlated. We introduce metrics to summarize a nation's overall “safety status,” and find that losses of longevity because of premature deaths are nearly three decades fewer in the safest countries than in the least safe ones. Turning to possible explanations for the cross-national differences, we find a strong association between a nation's safety status and both its economic wherewithal as indicated by the 2016 GDP per capita (adjusted for purchasing power parity) and its income inequality as reflected by its Gini coefficient.
