Impact of the patent system on the creation and diffusion of new technology

The paper summarises the results of several years research into the patent system at the Department of Applied Economics, University of Cambridge. Case studies of a number of large firms were carried out in four industries—chemicals (including pharmaceuticals), electrical engineering (including electronics), mechanical engineering and man-made fibres. In the light of these, the impact of the patent system on research and development, innovation, and the diffusion of new technology is considered. The patent system is found to be of marginal importance only, with the principal exception of the pharmaceutical industry. It is nevertheless found to have positive advantages for advanced industrial economies, as compared with a hypothetical weaker system.     

Rolling Out Anti‐social Behaviour Families Projects in England and Scotland: Analysing the Rhetoric and Practice of Policy Transfer

In both Scotland and England, reducing anti‐social behaviour (ASB) and building a culture of respect are key central government priorities. Accordingly, since 1997 both jurisdictions have seen the introduction of a raft of punitive legislation. Over recent years, however, there have been signs that the official ASB agenda has shifted away from a reliance on ‘enforcement measures’ towards a more balanced approach incorporating measures to address the underlying causes of problem behaviour. With their emphasis on ‘whole family’ approaches and parenting interventions, ASB family projects, pioneered by the Dundee Families Project (DFP), are seen to respond to official concerns about social exclusion and have been promoted as an effective and sustainable response to ASB. In both Scottish and English jurisdictions official endorsement of the DFP model has been marked by government‐funded programmes to ‘roll out’ this concept more widely. Drawing on findings from a recent evaluation of ASB family projects operating in Scotland combined with scrutiny of evidence from a number of English studies, this article explores, in a comparative manner, the differences and similarities in the policy discourses and models of practice employed by Scottish and English projects. More specifically, we critically appraise the role played by sanctions in evoking service user engagement.     

Workers’ Perception of Chemical Risks: A Focus Group Study

Workers’ perceptions with respect to health and safety at work are rarely taken into account when considering the development of prevention programs. The aim of this study was to explore workers’ perceptions of chemical risks at the workplace, in order to investigate the prerequisites for a workplace health program. A qualitative study was conducted involving seven focus groups of 5–10 participants (blue‐collar workers) each. All groups were homogeneous in terms of sex, work status, language, and company membership. Results showed that several factors have an important influence on workers’ perception of chemical risks. Workers assess risks by means of both sensory and empirical diagnosis and are concerned about the long‐term health consequences. They perceive the threat of chemical risks as high. Despite this, they are resigned to accepting the risks. Existing formal sources of information are rarely consulted because they are judged to be difficult to understand and not user friendly. Instead, workers tend to obtain information from informal sources. Communication problems with and lack of trust in prevention advisers and hierarchy are frequently mentioned. Workers feel that their specific knowledge of their working conditions and their proposals for practical, cost‐effective solutions to improve health and safety at the workplace are insufficiently taken into account. The use of focus groups yielded a useful insight into workers’ perceptions of chemical risks. Our findings suggest that training programs for prevention advisers should include topics such as understanding of workers’ perceptions, usefulness of a participatory approach, and communication and education skills.     

Going beyond vocational rehabilitation as a training of skills: return-to-work as an identity issue

In western welfare states, labour participation is increasingly considered a vital aspect of taking part in society. Vocational rehabilitation programmes are intended to support people in the process of returning to work. These programmes pay much attention to the skills that clients need to develop in order to return to work. We argue, however, that vocational rehabilitation is more than the acquirement of skills, and that further attention should be paid to clients’ ‘identity work’ processes. Based on 45 life-stories, we present an analysis of the identity work expressed by people with a work disability in the Netherlands. We describe ‘separative’, ‘integrative’, and ‘pending’ processes of identity work. The presented typology can help vocational rehabilitation professionals become more sensitive to clients’ processes, and supports more inclusive vocational rehabilitation.     

Long-Term Effects of a Parenting Preventive Intervention on Young Adults’ Attitudes Toward Divorce and Marriage

This study examined whether the New Beginnings Program (NBP), a parenting-focused preventive intervention designed to reduce children’s postdivorce mental health problems, affected attitudes toward divorce and marriage in young adults whose mothers had participated 15 years earlier. Participants (M = 25.6 years; 50% female; 88% White) were from 240 families that had participated in a randomized experimental trial (NBP vs. literature control). Analyses of covariance showed that program effects on both types of attitudes were moderated by gender. Males in the NBP reported more positive attitudes toward marriage and less favorable attitudes toward divorce than males in the literature control.     

One hundred years of suffering? “Humanitarian crisis photography” and self-representation in the Democratic Republic of the Congo

Humanitarian images streaming from the ongoing conflict in the eastern Democratic Republic of the Congo (DRC) are not “new”. In fact, contemporary aid and journalistic images strikingly mimic photographs created a century earlier during the Congo Reform Association’s humanitarian attack on Leopold II’s actions in the Congo Free State. This article explores the consistency of these photographic forms and their surrounding text, showing how the images of suffering are not simple reproductions of observed reality but carry personal, local and political meaning. By analysing image content as well as the subject and photographer’s experiences of image creation, this article expands beyond realist objectivity to encompass the subjects’ visual embodiment of subjective desires and expectations. Specifically, I examine how the photographic space composed of the photographer, camera and subject, becomes an intersection replete with competing expectations, hopes and tensions. To situate these images and their subjective, political and humanitarian weight within the DRC itself, I conclude with analysis of how the Congolese choose to present themselves to a different audience: themselves.

Modeled Estimates of Soil and Dust Ingestion Rates for Children

Daily soil/dust ingestion rates typically used in exposure and risk assessments are based on tracer element studies, which have a number of limitations and do not separate contributions from soil and dust. This article presents an alternate approach of modeling soil and dust ingestion via hand and object mouthing of children, using EPA's SHEDS model. Results for children 3 to <6 years old show that mean and 95th percentile total ingestion of soil and dust values are 68 and 224 mg/day, respectively; mean from soil ingestion, hand‐to‐mouth dust ingestion, and object‐to‐mouth dust ingestion are 41 mg/day, 20 mg/day, and 7 mg/day, respectively. In general, hand‐to‐mouth soil ingestion was the most important pathway, followed by hand‐to‐mouth dust ingestion, then object‐to‐mouth dust ingestion. The variability results are most sensitive to inputs on surface loadings, soil‐skin adherence, hand mouthing frequency, and hand washing frequency. The predicted total soil and dust ingestion fits a lognormal distribution with geometric mean = 35.7 and geometric standard deviation = 3.3. There are two uncertainty distributions, one below the 20th percentile and the other above. Modeled uncertainties ranged within a factor of 3–30. Mean modeled estimates for soil and dust ingestion are consistent with past information but lower than the central values recommended in the 2008 EPA Child‐Specific Exposure Factors Handbook. This new modeling approach, which predicts soil and dust ingestion by pathway, source type, population group, geographic location, and other factors, offers a better characterization of exposures relevant to health risk assessments as compared to using a single value.     

Issues, challenges, and solutions in translating study instruments

Cross-cultural adaptation of study instruments is a difficult, time-consuming, but arguably cost-effective process. If conducted properly, it has the advantage that the translated study instruments are accurate, easy to understand, accessible, and culturally appropriate to the target audience and produce reliable and valid data. This article explores issues, challenges, and solutions for translating a set of research instruments used in a randomized, controlled trial for four separate community languages (Chinese, Vietnamese, Greek, Italian).
