Theory and practice in teaching evaluation of intervention outcomes

This paper describes a course in the evaluation of intervention outcomes which combines classroom instruction with practical field work. The course was part of the BA programme in the Bob Shapell School of Social Work at Tel-Aviv University. It was given in conjunction with an advanced course in social work methods, and it entailed the active participation of the evaluation instructor, the methods instructor, and the fieldwork supervisor. To attain this integration, it was necessary not only to design the course but also to invest in training field supervisors, who could then serve as a resource for their students.

The paper emphasises the importance of cooperation between all those involved in teaching the course as well as the special significance of teaching the subject as part of the socialisation process of social work students. It also points out the various benefits both the students and instructors obtained from the course.     

Rapidly diffusing innovation: whether the history of the Internet points the way for hydrogen energy

This paper identifies conditions for the rapid diffusion of what may be part of the solution for global sustainable energy – hydrogen – by drawing a comparison with the contemporary history of the Internet. The Cold War drove the take-off of the Internet and state regulation ensured that the market on which its rapid diffusion came to depend was not controlled by corporations. To take-off and start to diffuse, hydrogen energy could similarly have to be considered a “public good”. However, the comparison with the Internet reveals differences too. The Internet diffused rapidly among the public at low cost to individual users, starting in the mid 1980s and kicking off in the 1990s. To achieve affordable hydrogen transport in the long term, many drivers might have to forgo cars for public transport. Moreover, global sustainable energy demands cooperation between nations rather than the conflict that spurred the Internet.     

Lost in Translation: Language,Terminology, and Understanding of Penile–Anal Intercourse in an HIV Prevention Trial in South Africa,Uganda, and Zimbabwe

Despite efforts to use culturally appropriate, understandable terms for sexual behavior in HIV prevention trials, the way in which participants interpret questions is underinvestigated and not well understood. We present findings from qualitative interviews with 88 women in South Africa, Uganda, and Zimbabwe who had previously participated in an HIV prevention trial. Findings suggested that participants may have misinterpreted questions pertaining to penile–anal intercourse (PAI) to refer to vaginal sex from behind and subsequently misreported the behavior. Three key issues emerge from these findings: first, the underreporting of socially stigmatized sexual behaviors due to social desirability bias; second, the inaccurate reporting of sexual behaviors due to miscomprehension of research terms; and third, the ambiguity in vernacular terms for sexual behavior and lack of acceptable terms for PAI in some languages. These findings highlight methodological challenges around developing clear and unambiguous definitions for sexual behaviors, with implications not only for clinical trials but also for clinical practice and sexual risk assessment. We discuss the challenges in collecting accurate and reliable data on heterosexual PAI in Africa and make recommendations for improved data collection on sensitive behaviors.     

Family Therapy with the Elderly

This article outlines health and lifestyle challenges to elderly persons and associated changes in their family systems. Flexibility, related to attachment patterns, is considered central to healthy adaptation. Family therapy approaches and relevant systemic and cultural factors influencing psychotherapy with the elderly are discussed. Key family therapy concepts and strategies (genograms, transmission of family histories and circular patterns of interaction), are reviewed and exemplified. Four types of family therapy presentations are elucidated by composite case examples. Firstly, the elderly person can be the identified patient. Secondly, another family member can seek help for him/herself in relation to the elderly person. Thirdly, another family member can be the identified patient without direct reference to the elderly person. Finally, the wider health care system involved with the elderly person and family can be the focus of therapy. Family therapy offers important conceptual and strategic advantages in working with the elderly and their systems.

The development of interindividual differences in sympathy: The role of child personality and adults’ responsiveness to distress

In a three‐wave longitudinal study of 85 children (43 girls) at 5, 6, and 7 years of age, the role played by child personality (inhibition, aggressiveness) and adults’ responsiveness to distress in children's sympathy was examined. At all three times, sympathy was measured via standardized observations as well as children's self‐reports. Child inhibition and aggressiveness were assessed with reports by teachers at T1 and T2. Parents’ and teachers’ responsiveness to distress were inferred from interviews with the children at T1 and T2. Longitudinal analyses via latent regression using structural equation models showed that earlier sympathy explained most of the variance in later sympathy. Additionally, higher inhibition at T1 predicted less sympathy at T2. Higher sympathy at T1 predicted more adult responsiveness at T2. Higher aggressiveness at T2 predicted less sympathy at T3. Within time, at T1, sympathy was positively related to adults’ responsiveness. At T2, inhibition and sympathy were negatively related. The discussion focuses on the question of how child personality as well as parental and non‐parental socialization experiences work in concert to explain interindividual differences in sympathy.     

An Interagency Comparison of Screening-Level Risk Assessment Approaches

Approaches to risk assessment have been shown to vary among regulatory agencies and across jurisdictional boundaries according to the different assumptions and justifications used. Approaches to screening-level risk assessment from six international agencies were applied to an urban case study focusing on benzo[a]pyrene (B[a]P) exposure and compared in order to provide insight into the differences between agency methods, assumptions, and justifications. Exposure estimates ranged four-fold, with most of the dose stemming from exposure to animal products (8-73%) and plant products (24-88%). Total cancer risk across agencies varied by two orders of magnitude, with exposure to air and plant and animal products contributing most to total cancer risk, while the air contribution showed the greatest variability (1-99%). Variability in cancer risk of 100-fold was attributed to choices of toxicological reference values (TRVs), either based on a combination of epidemiological and animal data, or on animal data. The contribution and importance of the urban exposure pathway for cancer risk varied according to the TRV and, ultimately, according to differences in risk assessment assumptions and guidance. While all agency risk assessment methods are predicated on science, the study results suggest that the largest impact on the differential assessment of risk by international agencies comes from policy and judgment, rather than science.     

Complements or substitutes? The contingent role of corporate reputation on the interplay between internal R&D and external knowledge sourcing

Existing research does not provide a clear answer to the question of whether internal knowledge development and external knowledge sourcing are complementary or substitutive innovation activities. This paper adopts a contingent approach for addressing this issue by examining whether and how the interactive effect of internal R&D efforts and external knowledge sourcing on product innovation performance may be affected by the firm’s corporate reputation. In doing so, a three-way interaction model is applied to a sample of 251 Spanish high-technology manufacturing firms. Interestingly, initial results support the substitutive argument: the positive effect of internal R&D on product innovation performance diminishes as the exposure to external knowledge increases. However, in well reputed companies, interaction becomes positive, revealing a complementary effect. Thus, the study extends the traditional approach focused on determining whether internal and external knowledge sourcing are complements or substitutes by showing that their interplay depends on other firm-specific characteristics. Moreover, identifying corporate reputation as a source of complementarity between both activities provides an additional explanation of how corporate reputation contributes to a more effective management of knowledge assets.
