The HOPE Family Project: A Family-Based Group Intervention to Reduce the Impact of Homelessness on HIV/STI and Drug Risk Behaviors

The HOPE Family Project (HIV Prevention for Parents and Early Adolescents) is an eight- session, family-based group intervention modeled on three evidence-based curricula targeting HIV/AIDS and alcohol and drug abuse prevention. The design and implementation of the HOPE Family Project was carried out by an established community collaborative board. The project aims to educate and provide tailored support to families and their youth (ages 11–14), residing in homeless shelters, regarding HIV and alcohol abuse prevention. The group model proved successful in offering an informal social support network for families living in homeless shelters and improving family functioning and youth mental health outcomes.     

Informal Referrals,Employment, and Wages: Seeking Causal Relationships

Employers and job seekers rely extensively on informal referrals to fill vacancies or to find a job. The widespread use of job contacts has been largely associated with labor outcomes, such as finding a job or even affecting wages. This paper explores whether the use of informal referrals on the job search process affects labor market outcomes of Colombian urban workers. Results indicate that informal referrals are slightly more successful than other job search strategies in term of job seeker's placement. However, referred workers earn in average less than their non‐referred counterparts. Yet, this is only true in formal‐sector positions.     

Benefactors and Beneficiaries: The Effects of Giving and Receiving on Cost‐Coalitional Problems

Motivated by supply chain collaborations in practice, we introduce a class of cost‐coalitional problems, which are based on a priori information about the cost faced by each agent in each set that it could belong to. Our focus is on problems with decreasingly monotonic coalitional costs. In this class of problems, we study the effects of giving and receiving when there exist players whose participation in an alliance always contributes to the savings of all alliance members (we refer to these players as benefactors), and there also exist players whose cost decreases in such an alliance (we call them beneficiaries). We use linear and quadratic norm cost games to analyze the role played by benefactors and beneficiaries in achieving stability of different cooperating alliances. We consider different notions of stability (the core and the bargaining set) and provide conditions for stability of an all‐inclusive alliance of agents which leads to minimum value of total cost incurred by all agents.     

Evaluation of performance of European cities with the aim to promote quality of life improvements

This paper explores the possibilities presented by DEA to assess quality of life and evaluate the performance of city managers in what concerns the promotion of urban quality of life. Using the data provided by the Urban Audit program, from the European Union, we defined the city profile regarding quality of life for 206 cities. Two approaches are presented: the construction of a composite indicator of quality of life and the assessment of local management performance, contextualised by the GDP per capita to measure the ability of local authorities to promote quality of life given the economic condition of the country. The results identify the cities with urban best practices and present a model of intervention for the cities considered inefficient, based on benchmarking principles.     

Alcohol Use and Popularity: Social Payoffs From Conforming to Peers' Behavior

Although many economic analyses of adolescents have examined the costs of risky behaviors, few have investigated the gains that young people derive from such actions, particularly in terms of social payoffs for complying with peer behavior. This paper studies the relationship between adolescents' use of alcohol (relative to that of their peers) and popularity at school. We use data from the National Longitudinal Study of Adolescent Health, a rich and nationally representative survey with detailed information on social networks. Our findings suggest that adolescents are socially rewarded for conforming to their peers' alcohol use and penalized (to a lesser degree) for increasing their consumption above that of their peers. Male adolescents are rewarded for keeping up with their peers' drinking and for getting drunk. Female adolescents are rewarded for drinking per se, but not necessarily for keeping up with their peers. The results offer new information on peer influence and have implications for substance abuse interventions at school and in the community.     

Integrated scheduling and inventory management of an oil products distribution system

The oil supply chain is facing new challenges due to emerging issues such as new alternative energy sources, oil sources scarcity, and price variability with high impact on demand and production and profit margins reduction. Additionally, the existence of large, complex and world wide spread businesses implies a complex system to be managed where distribution can be seen as one of the key areas that needs to be efficiently and effectively managed. Different types of distribution modes characterize the oil supply chain where the pipeline mode is one of the most complex to operate when having multiproduct characteristics. This paper addresses the planning of a generic oil derivatives transportation system characterized by a multiproduct pipeline that connects a single refinery to a storage tank farm. Two alternative mixed integer linear programming models (MILP) that aim to attain a set of planning objectives such as fulfilling costumers’ demands (which is mandatory) while minimizing the medium flow rate are developed. Additionally, final inventory levels are avoided to be excessively low. A real world scenario of a Portuguese company is used to validate and compare the two alternative MILP models developed in this paper.

The Impact of Childhood Sexual Abuse on Later Sexual Victimization among Runaway Youth

Path analysis was used to investigate the impact of childhood sexual abuse on later sexual victimization among 372 homeless and runaway youth in Seattle. Young people were interviewed directly on the streets and in shelters by outreach workers in youth service agencies. High rates of both childhood sexual abuse and street sexual victimization were reported, with females experiencing much greater rates compared with their male counterparts. Early sexual abuse in the home increased the likelihood of later sexual victimization on the streets indirectly by increasing the amount of time at risk, deviant peer affiliations, participating in deviant subsistence strategies, and engaging in survival sex. These findings suggest that exposure to dysfunctional and disorganized homes place youth on trajectories for early independence. Subsequently, street life and participation in high‐risk behaviors increases their probability of sexual victimization.     

Adult self-sufficiency and social adjustment in care leavers from children's homes: a long-term assessment

This paper presents a study carried out in Spain that followed up 260 young people, the majority of them adults, who had been in residential care for significant periods. The follow‐up takes place between 1 and 9 years after participants had left residential care, and assesses their level of social and work integration, as well as considering the incidence of problems related to marginalization and social exclusion. Furthermore, it analyses the reasons for the child being taken into care, the socio‐family context, length of stay, changes in placement and other features or incidents in relation to the residential care. The data show that close to 15% have serious problems (drug dependence, delinquency, etc.), 25% receive help from the social services and the rest manage independently to a greater or lesser extent. We discuss the significance of these data, especially the relationship between the final result and the initial and process variables.
