A Strategic Approach to Agricultural Research Program Planning in Sub-Saharan Africa
Recent studies have shown that agricultural research can have high payoffs in Africa, but impact depends on how well technology fits with evolving needs and capacity in the agricultural sector and the rest of the economy. Structural adjustment policies (e.g., market liberalization, currency devaluation) and political change are transforming user demands for new technology and the economic environment in which technology must perform. The challenge is how to design agricultural research as a strategic input to promote broad-based economic growth, structural transformation, and food security in the increasingly market-driven, but fragile, economies of Africa.Food Security, Food Policy, Agricultural Research, Research and Development/Tech Change/Emerging Technologies, Downloads May 2008-July 2009: 44, Q18,

The Epidemiology of College Alcohol and Gambling Policies
Background: This article reports the first national assessment of patterns of drinking and gambling-related rulemaking on college campuses (e.g., punitive versus recovery oriented). Analyses relating school policies to known school rates of drinking or gambling identified potentially influential policies. These results can inform and encourage the development of guidelines, or "best practices," upon which schools can base future policy. Methods: The college policy information was collected from handbooks, Web sites and supplemental materials of 119 scientifically selected colleges included in the fourth (2001) Harvard School of Public Health College Alcohol Study (CAS). A coding instrument of 40 items measured the scope and focus of school alcohol and gambling policies. This instrument included items to measure the presence of specific policies and establish whether the policies were punitive or rehabilitative. A total of 11 coders followed a process of information extraction, coding and arbitration used successfully in other published studies to codify policy information. Results: Although all schools had a student alcohol use policy, only 26 schools (22%) had a gambling policy. Punitive and restrictive alcohol policies were most prevalent; recovery-oriented policies were present at fewer than 30% of schools. Certain alcohol and gambling policies had significant relationships with student binge drinking rates. Conclusions: The relative lack of college recovery-oriented policies suggests that schools might be overlooking the value of rehabilitative measures in reducing addictive behaviors among students. Since there are few college gambling-related policies, schools might be missing an opportunity to inform students about the dangers of excessive gambling

Virtual harm reduction efforts for Internet gambling: effects of deposit limits on actual Internet sports gambling behavior
Background: In an attempt to reduce harm related to gambling problems, an Internet sports betting service provider, bwin Interactive Entertainment, AG (bwin), imposes limits on the amount of money that users can deposit into their online gambling accounts. We examined the effects of these limits on gambling behavior. Methods: We compared (1) gambling behavior of those who exceeded deposit limits with those who did not, and (2) gambling behavior before and after exceeding deposit limits. We analyzed 2 years of the actual sports gambling behavior records of 47000 subscribers to bwin. Results: Only 160 (0.3%) exceeded deposit limits at least once. Gamblers who exceeded deposit limits evidenced higher average number of bets per active betting day and higher average size of bets than gamblers who did not exceed deposit limits. Comparing the gambling behavior before and after exceeding deposit limits revealed slightly more unfavorable gambling behavior after exceeding deposit limits. Conclusion: Our findings indicate that Internet gamblers who exceed deposit limits constitute a group of bettors willing to take high risks; yet, surprisingly, they appear to do this rather successfully because their percentage of losses is lower than others in the sample. However, some of these gamblers exhibit some poor outcomes. Deposit limits might be necessary harm reduction measures to prevent the loss of extremely large amounts of money and cases of bankruptcy. We discuss how these limits might be modified based on our findings
The Common Sense of Counseling Psychology: Introducing
The goal of therapy is typically to improve clientsâ self-management of their problems, not only during the course of therapy but also after therapy ends. Although it seems obvious that therapists are interested in improving clientâs self-management, the psychotherapy literature has little to say on the topic. This article introduces Leventhalâs Common-Sense Model of Self-Regulation, a theoretical model of the self-management of health, and applies the model to the therapeutic process. The Common-Sense Model proposes that people develop illness representations of health threats and these illness representations guide self-management. The model has primarily been used to understand how people self-manage physical health problems, we propose it may also be useful to understand self-management of mental health problems. The Common-Sense Modelâs strengths-based perspective is a natural fit for the work of counseling psychologists. In particular, the model has important practical implicationsfor addressing how clients understand mental health problems over the course of treatment and self-manage these problems during and after treatment

Une approche stratégique pour la planification du programme de recherche agricole en Afrique sub-saharienne
Des études récentes ont montré que la recherche agricole en Afrique peut avoir une rentabilité élevée, mais son impact dépend de l'adaptabilité des nouvelles technologies aux capacités et aux besoins changeants du secteur agricole et du reste de l'économie. Les politiques d'ajustement structurel (ex : la libéralisation des marchés et la dévaluation monétaire) et les changements politiques sont en train de transformer la demande de nouvelles technologies et l'environnement économique au sein duquel ces technologies doivent opérer. Le défi est de concevoir la recherche agricole comme un intrant stratégique qui encourage une croissance économique à base élargie, la transformation structurelle de l'économie et la sécurité alimentaire dans des économies africaines de plus de plus orientées vers la production pour la commercialisation mais qui restent encore fragiles.food security, food policy, agricultural research, Research and Development/Tech Change/Emerging Technologies, Downloads June 2008-June 2009: 11, Q18,
Local structure and polar order in liquid N-Methyl-2-pyrrolidone (NMP)
N-Methyl-2-pyrrolidone (NMP) is an exceptional solvent, widely used in industry and for nanomaterials processing. Yet despite its ubiquity, its liquid structure, which ultimately dictates its solvation properties, is not fully known. Here, neutron scattering is used to determine NMPâs structure in unprecedented detail. Two dominant nearest-neighbor arrangements are found, where rings are parallel or perpendicular. However, compared with related solvents, NMP has a relatively large population of parallel approaches, similar only to benzene, despite its nonaromaticity and the presence of the normally structure-reducing methyl group. This arrangement is underpinned by NMPâs dipole moment, which has a profound effect on its structure: nearest-neighbor molecules arrange in an antiparallel but offset fashion. This polar-induced order extends beyond the first solvation shell, resulting in ordered trimers that reach the nanometer range. The degree of order and balance of interactions rationalize NMPâs high boiling point and versatile capabilities to solvate both charged and uncharged species
