AIDS and kitchen gardens: insights from a village in Western Kenya

In rural Africa, indigenous farming and natural resource management systems exemplified by kitchen gardens are being reshaped by the HIV/AIDS epidemic and its negative impacts (illness, stigma and mortality, and economic costs) and positive opportunities (organizational responses to the epidemic). Subtle changes in crops and farm techniques can be traced to these diverse influences of HIV+ infection, illness, mortality, widowhood, foster child care, and AIDS support groups, as well as the organizations, ideas, and flow of funding from outside. These findings draw on original field data: a village census, in-depth interviews with gardeners, and group discussions in a village in Bungoma District (in 2005 and 2007). This part of western Kenya is a typical small-farm zone that has faced a moderate HIV/AIDS epidemic since the 1990s, following decades of demographic, environmental, technological, and institutional changes. Implications of this case study for further research on HIV/AIDS and on micro-level population–environment change suggest that households are useful but imperfect analytical units and are best seen as part of complex social networks, shaping connections to markets. These important “mediating institutions” link AIDS as a demographic and economic force with environmental outcomes in cultivated landscapes.     

Strategy Alternatives for Homeland Air and Cruise Missile Defense

Air and cruise missile defense of the U.S. homeland is characterized by a requirement to protect a large number of critical assets nonuniformly dispersed over a vast area with relatively few defensive systems. In this article, we explore strategy alternatives to make the best use of existing defense resources and suggest this approach as a means of reducing risk while mitigating the cost of developing and acquiring new systems. We frame the issue as an attacker‐defender problem with simultaneous moves. First, we outline and examine the relatively simple problem of defending comparatively few locations with two surveillance systems. Second, we present our analysis and findings for a more realistic scenario that includes a representative list of U.S. critical assets. Third, we investigate sensitivity to defensive strategic choices in the more realistic scenario. As part of this investigation, we describe two complementary computational methods that, under certain circumstances, allow one to reduce large computational problems to a more manageable size. Finally, we demonstrate that strategic choices can be an important supplement to material solutions and can, in some cases, be a more cost‐effective alternative.     

A Note on Derived Means of Scaled Data

Details are given of the procedures for calculating derived means of square-root and log transformed variables from un-subdivided and layered samples. A method for determining approximate confidence limits of the derived means is also described. The temporal distribution of nematodes in grass herbage is given as an example to illustrate the procedures used.     

Demographic change and the supply of potential family supporters in Britain, Finland and France in the period 1911–2050/Changements démographiques et disponibilité des soutiens familiaux en Grande-Bretagne, en Finlande et en France entre 1911 et 2050

We consider the contribution of changes in mortality and fertility to availability of living mothers and living children among older people in Britain, Finland and France. The proportion of people aged around 60 with a mother alive will more than double between those born in 1911 and 1970 before starting to decline slightly. Conversely, a higher proportion of elderly people are likely to have a surviving child than for any generation ever born in all three countries in the next quarter century or so, with about 85% of 80-year-old women having at least one surviving child, and about two-thirds having two or more.     

An Integrative Examination of Peer Conflict: Children's Reported Goals, Emotions, and Behaviors

The primary purpose of the present study was to examine the interrelations among children's typical emotions, goals, and behavior during peer conflict and to examine emotions and goals as joint predictors of behavior. Children (7 to 11 years old) described recent conflicts with peers and were questioned about their emotions, goals, and behaviors. The friendliness of children's reported goals during conflict was associated with low anger intensity and with high intensity of sadness. Children who tended to report nonconstructive behavior also tended to report relatively intense anger and relatively unfriendly goals. Furthermore, in regression analyses, the friendliness of goals uniquely predicted the constructiveness of children's behavior after controlling for the effects of anger intensity, age, gender, provoking event, and friendship with the peer. Although boys and girls reported similar levels of anger and sadness, girls reported friendlier goals and more constructive behavior than did boys. The use of self‐reports of actual events to examine peer conflict during middle childhood is also discussed.     

Demographic event history analysis: a selective review

This is a selective review of the literature concerning demographic event history analysis. "We have attempted to emphasize work that we consider to be particularly important or innovative, to note some of the difficulties that may arise with the use of event history analysis, and to point to several substantive areas where research is still poorly developed."     

Clinical reengineering. Integrating medical and operational management

In the continuing push for cost containment in health care, many organizations have turned to cost reduction methods that fundamentally change the way care is delivered. As health care organizations continue to make financially-driven staffing changes that impact patient care, medical leadership must take on greater responsibility for operational management. Physician executives are uniquely qualified to take on leadership roles in work redesign, and must do so to ensure excellent and fiscally-responsible patient care. This article presents a proven methodology for work redesign that helps physician executives apply their clinical skills to operational management in designing new health care delivery models.     

The Relationship between Bullying Roles and Children's Everyday Dyadic Interactions

This study investigated the behaviour and communication of seven‐ to eight‐year‐old children during a dyadic computer task. The children participating were identified by peers as: (1) initiators of bullying (‘bullies’); (2) defenders of those victimised (‘defenders’); and (3) those who generally do not take on a consistent role in relation to bullying (‘non‐role’ children). Children were videotaped during the task and the interaction was coded, 34 dyads participated. Defenders used significantly higher levels of supportive communication such as explanation and guidance than bullies. The task performance of dyads consisting of defenders with non‐role children was significantly superior to that of dyads comprising bullies plus non‐role children. The behaviour of the non‐role children was influenced according to whether they were working with a bully, a defender or another non‐role child. The study suggests that the roles that children adopt in relation to bullying influence their behaviour in other, non‐bullying contexts.     

Bullying behaviour in secondary schools: what roles do teachers play?

Teachers have an important role to play in the management and prevention of bullying. Although many anti‐bullying programmes advocate a ‘whole school approach’, they tend to focus on student‐student behaviours and rarely examine the nature of other relationships which exist in the school. This study examines bullying between students and teachers at two time points. Thirty per cent of students said they were bullied by teachers at both times. Numbers reporting they bullied teachers were 28 per cent and 16 per cent, respectively. The paper explores the important role that teachers play in dealing with bullying in a school setting by modelling appropriate behaviours and dealing with it effectively. If teachers are victimised by or engage in bullying students this has implications for the ethos within the school and may also impact on the success of anti‐bullying programmes.
