The undercut procedure: an algorithm for the envy-free division of indivisible items

We propose a procedure for dividing a set of indivisible items between two players. We assume that each player’s preference over subsets of items is consistent with a strict ranking of the items, and that neither player has information about the other’s preferences. Our procedure ensures an envy-free division—each player receives a subset of items that it values more than the other player’s complementary subset—given that an envy-free division of “contested items,” which the players would choose at the same time, is possible. We show that the possibility of one player’s undercutting the other’s proposal, and implementing the reduced subset for himself or herself, makes the proposer “reasonable,” and generally leads to an envy-free division, even when the players rank items exactly the same. Although the undercut procedure is manipulable and its envy-free allocation may be Pareto-inferior, each player’s maximin strategy is to be truthful. Applications of the procedure are discussed briefly.     

How does Conflict in Migrants’ Country of Origin Affect Remittance‐Sending? Financial Priorities and Transnational Obligations Among Somalis and Pakistanis in Norway

This article examines how conflict in the country of origin interacts with other factors in shaping migrants’ remittance‐sending practices. Our data come from a survey of 10 immigrant groups in Norway and semi‐structured interviews with Somali and Pakistani remittance‐senders and receivers. First, we conduct an in‐depth comparison to explore the differences in how Somali and Pakistani migrants decide about remittance‐sending. Second, we use survey data on all 10 migrant groups to evaluate whether the differences that are not explained by socioeconomic characteristics, may partly reflect whether or not there is ongoing conflict in the country of origin. In our analyses we differentiate between (1) the effect of migrants’capacity to remit and their prioritizing of local and transnational expenditures, and (2) the impact of state collapse and absence of human security on migrants’ and refugees’desire to remit. We find that ongoing conflict in the country of origin exerts an upward pressure on remittance‐sending.     

Cultural Responses to Changing Gender Patterns of Migration in Georgia

In this paper, we explore how individual women cope with the tensions between economic forces encouraging temporary labour migration and cultural norms tying “proper” women to their homes and families. Combining in‐depth interviews with returned migrant women in the Georgian capital of Tbilisi with secondary migration data for the region, we illustrate the recent increases in Georgian women’s participation in international labour migration. Deteriorating economic conditions in Georgia leave women with few local opportunities to financially support their families, while institutional changes have altered the accessibility and attractiveness of international destinations, leading to increasing motivations and opportunities for women’s migration. Focusing on the contradictions between growing female migration and persistent adherence to cultural norms stigmatizing migration in Georgia, we explore the cognitive strategies migrant women employ in an attempt to balance internalized perceptions of acceptable gendered behaviour with their migration choices. Two key pathways of adaptation emerge: framing migration as a necessity rather than a choice and stressing the unique and individually exceptional nature of their own migration experience. We posit that these strategies may serve to limit the norm‐challenging nature of women’s migration in Georgia. Although migration is often described as an empowering experience for women, if women migrants work to present their migration in a way that fits within the bounds of traditional gender norms, these norms may be strengthened rather than challenged.     

Collaborative evaluation of a high school prevention curriculum: How methods of collaborative evaluation enhanced a randomized control trial to inform program improvement

Blending high-quality and rigorous research with pure evaluation practice can often be best accomplished through thoughtful collaboration. The evaluation of a high school drug prevention program (All Stars Senior) is an example of how perceived competing purposes and methodologies can coexist to investigate formative and summative outcome variables that can be used for program improvement. Throughout this project there were many examples of client learning from evaluator and evaluator learning from client. This article presents convincing evidence that collaborative evaluation can improve the design, implementation, and findings of the randomized control trial. Throughout this paper, we discuss many examples of good science, good evaluation, and other practical benefits of practicing collaborative evaluation. Ultimately, the authors created the term pre-formative evaluation to describe the period prior to data collection and before program implementation, when collaborative evaluation can inform program improvement.     

Evaluation of a school-based sexual abuse prevention curriculum in Malaysia

This article examines a personal safety curriculum (Keeping Me Safe) offered to Standard Three students (mostly nine-year-olds) in five primary schools in Kuala Lumpur, Malaysia. Staff of the Malaysian NGO, Protect and Save the Children, Association of Selangor and Kuala Lumpur (P.S. The Children), facilitated six weekly one-hour sessions featuring games and role play to teach children about potentially unsafe situations and touches, and to develop appropriate safety strategies and skills to ask for help. The students (n = 261) and a control group (n = 184) completed a 25 item questionnaire before and after the program, and for the experimental group only, again two months later. The assessment was supplemented by observations of each session, student interviews, and parent and teacher focus groups. The experimental group students showed substantial gains on about two-thirds of the questionnaire items. However, a minority of the students failed to absorb key messages of the curriculum. Challenges to implementing prevention programs in Malaysia are discussed.     

Review of outcome research on marital and family therapy in treatment for alcoholism

This review of controlled studies of marital and family therapy (MFT) in alcoholism treatment updates the earlier review by O'Farrell and Fals-Stewart (2003). We conclude that, when the alcoholic is unwilling to seek help, MFT is effective in helping the family cope better and motivating alcoholics to enter treatment. Specifically, both Al-Anon facilitation and referral and spouse coping skills training (based on new findings) help family members cope better, and CRAFT promotes treatment entry and was successfully transported to a community clinic in a new study. Once the alcoholic enters treatment, MFT, particularly behavioral couples therapy (BCT), is clearly more effective than individual treatment at increasing abstinence and improving relationship functioning. New BCT studies showed efficacy with women alcoholics and with gay and lesbian alcoholics, and BCT was successfully transported to a community clinic, a brief BCT version was tested, and BCT was adapted for family members other than spouses. Future studies should evaluate the following: MFT with couples where both members have a current alcohol problem and with minority patients, mechanisms of change, transportability of evidence-based MFT approaches to clinical practice settings, and replication of MFT outcomes of reduced partner violence and improved child functioning.     

Relationship education research: current status and future directions

The overarching aim of this article is to review the research on relationship education programs and approaches that has been published or accepted for publication since the last review article in 2003. This article provides a critical overview of the relationship education field and sets an agenda for research and practice for the next decade. A theme weaved throughout the article is the ways in which relationship education is similar and different from couples therapy, and we conclude that there can be a synergistic, healthy marriage between the two. We then provide recommendations for future directions for research in the relationship education field. Finally, the coauthors comment on our experiences in both the relationship education field and the couples therapy field as both researchers and interventionists.     

Attention Capture by Direct Gaze is Robust to Context and Task Demands

Eye-tracking was used to investigate whether gaze direction would influence the visual scanning of faces, when presented in the context of a full character, in different social settings, and with different task demands. Participants viewed individual computer agents against either a blank background or a bar scene setting, during both a free-viewing task and an attractiveness rating task for each character. Faces with a direct gaze were viewed longer than faces with an averted gaze regardless of body context, social settings, and task demands. Additionally, participants evaluated characters with a direct gaze as more attractive than characters with an averted gaze. These results, obtained with pictures of computer agents rather than real people, suggest that direct gaze is a powerful attention grabbing stimulus that is robust to background context or task demands.     

Engaging stakeholders through Twitter: How nonprofit organizations are getting more out of 140 characters or less

While it may seem difficult to communicate in a meaningful manner with 140 characters or less, Twitter users have found creative ways to get the most out of each Tweet by using different communication tools. This paper looks into how 73 nonprofit organizations use Twitter to engage stakeholders not only through their tweets, but also through other various communication methods. Specifically it looks into the organizations utilization of tweet frequency, following behavior, hyperlinks, hashtags, public messages, retweets, and multimedia files. After analyzing 4655 tweets, the study found that the nation's largest nonprofits are not using Twitter to maximize stakeholder involvement. Instead, they continue to use social media as a one-way communication channel as less than 20% of their total tweets demonstrate conversations and roughly 16% demonstrate indirect connections to specific users.     

Understanding the relationship between social change and its impacts: The experience of rural land use change in south-eastern Australia

This study investigated socio-economic impacts of land use change, giving explicit attention to the relationships between independently observed land use change and associated socio-economic changes, perceived land use change and socio-economic change, attributed cause of change, and experienced impacts of change. Using a case study region in south-east Australia, we examined the impacts of growth in use of land for dairy farming, cropping, blue gum plantations and rural residential development on (i) rural population trends, and (ii) the amount and nature of employment available in the study region. Perceptions and impacts of change were assessed using multiple qualitative and quantitative methods. Results demonstrate that local residents were not always aware of the extent and nature of land use change, and had difficulty attributing social changes and their impacts to the land use changes that underlie them. Furthermore, the felt impacts of land use change appeared dependent on a person's awareness of that change, and on their beliefs about the causes of social change. These findings highlight avenues for theoretical development to better specify the processes by which social change processes are experienced as human impacts. The findings also have implications for land use policy and social impact assessment, illustrating the importance of understanding both perceived and actual social change.
