Over the past few months there has been renewed debate at the UK Intellectual Property Office (“UK IPO”) and in the UK courts over whether computer programs can be considered patentable inventions. In particular, concern persists that the UK authorities and the European Patent Office (“EPO”) are applying different tests for the patentability of computer software, even though they are applying the same legislation. This article reviews the positions taken by the UK and the EPO tribunals, and how these impact upon businesses wishing to patent inventions encompassed in software.  相似文献

We evaluate the cost‐effectiveness of two early childhood interventions that use instructional coaching and parent coaching as levers for improvement. The study design allows us to compare the individual effects of each intervention as well as their combined effect on student outcomes. We find that teachers receiving instructional coaching improve their use of evidence‐based instructional practices, while families receiving parent coaching show increases in numerous responsive parenting behaviors associated with positive child outcomes. Both interventions demonstrate positive impacts on students, but only parent coaching shows statistically significant effects across a range of student outcomes. Instructional coaching alone is substantially less costly and may therefore be the most cost‐effective of the three treatment conditions; however, small sample sizes limit our ability to reach definitive conclusions. Policy simulations suggest that implementing these interventions could raise the overall cost‐effectiveness of Head Start by at least 16 percent.  相似文献

The energy industry, especially the petroleum, is critically important to today's society. This industry has historically been accused of being a “good old boy” network that is extremely reluctant and slow to accept technology and change. A closer analysis of the industry shows that it is highly fragmented consisting mostly of firms who operate in only a limited number of functional areas. The analysis also shows that there are many critical current and future problems which could be addressed with technology from any diverse disciplines and industries. Case analyses of existing technology flow through to successful utilization by the petroleum industry describes the technology transfer process and the role played by the different firms inside and outside the industry.  相似文献

This study was part of a series designed to validate a classification system for rapists developed at the Massachusetts Treatment Center. This system (MTC:R2) determines subtypes according to three major dimensions: the meaning of the aggression in the rapist's offenses (expressive versus instrumental), the meaning of the sexual behavior (compensatory, exploitative, displaced anger, or sadistic), and the degree of general lifestyle impulsivity (low or high). A total of 201 rapists were subtyped using this system. A path analytic approach was used to relate family, juvenile, and adult histories to the main decisions of subtype assignment. The classification of an offender on each of the three dimensions was informed by a developmental perspective. Results provided support for the use of the discriminators used and highlighted the deficiencies in our current knowledge regarding developmental precursors. These results were integrated with the findings from other studies using MTC:R2 and suggestions for revisions to the current classification system were discussed.  相似文献

  • This paper examines the very long‐running trade dispute between Australia and New Zealand concerning a ban on the importation of apples on the basis of fire blight disease present in New Zealand. This particular example illustrates the more general case of the frequent conflict between science and politics in regard to technical trade barriers. This same issue of fire blight disease in apples became the subject of a protracted World Trade Organization dispute between the USA and Japan, with New Zealand a third party to the USA, and Australia a third party to Japan. The World Trade Organization Dispute Settlement Body, and subsequently the World Trade Organization Appellate Body, ruled in favour of the USA (and thus New Zealand) on this issue. Despite this ruling, Australia has continued its ban on New Zealand apples and the issue has become highly politicized in Australia.
  • This case highlights the need for World Trade Organization rules to be changed to ensure that its rulings become binding on third parties and other World Trade Organization members. This would ensure that once an issue is decided through the full World Trade Organization conflict resolution process, the principles established should become generally applicable to other instances of the same scientific issue.

Commission of nonsexual crimes generally antedates officially recorded sexual offenses. In particular, burglary has been hypothesized to be a potential ‘stepping stone’ in the development of one's sexual criminal career in the same way that marijuana has often been considered a ‘gateway drug’ to more serious drug-related offenses. The present study examined the officially recorded criminal histories of 828 male sex offenders to determine the relevance of burglary in their criminal histories. One third of the men in the sample (n=281, 34%) had been charged at least once for burglary. These 281 men committed a total of 762 separate incidents of burglary. Offenders with at least one officially recorded charge for burglary (BSOs) were compared with those with no such charges (SOs). Next, the characteristics of each burglary were examined and four distinct types of burglary were identified: nonsexual, covertly sexual, overtly sexual, and combination burglary/rape. BSOs accrued twice as many charges as the SOs and were significantly more likely to have an earlier age of onset, a longer criminal career, more employment problems, elementary school problems, antisocial behavior, and substance abuse.  相似文献

This article describes a new effort to engage in analytic outreach between academic scholars and intelligence analysts on the issue of emerging biotechnology threats to US national security. The context of this outreach was a September 2012 meeting in London to explore possibilities for enhanced analytic outreach in relation to emerging biotechnology threats, supported by the UK Genomics Policy and Research Forum. This meeting consisted of a mix of current and former intelligence practitioners and policy officials, and social science and scientific experts, from both the UK and the US. As will be described below, this unique pairing of experts and subjects revealed new insights into how to improve intelligence assessments on biotechnology and bioweapons threats. It also revealed continuing challenges in reforming assessments within existing intelligence work routines.  相似文献

The study of migrant workers in Hong Kong has given attention to Filipinas. There has been just one published study of Thais in Hong Kong, despite the fact that they are a significant minority, and about half of them are domestic workers. This article presents the results of a survey of Thai workers, assessing a range of issues: scale of migration for work, remittances, roles and aspirations in Hong Kong, and perceptions of work. The survey indicated that the Thais interviewed were reasonably satisfied with their life in Hong Kong. While most are involved in “low status” activities, Thais appear to do better than Indonesian migrant workers in terms of the wages and conditions they achieve, and report less abuse. In broader terms, migrant labour is one option amongst many for working class Thais seeking better incomes but seldom achieving upward class mobility].  相似文献
