A unique longitudinal study of the technical communication patterns of 184 engineers in a high technology research and development laboratory centers in the activities of technology gatekeepers. This two-step flow of technical information follows the literature as well as results from prior studies. Gatekeepers span the organizational boundary in the transfer of technology from outside the laboratory, while facilitating the distribution of technical information to colleagues within the organization. Sociometric data are analyzed over a five-year period with respect to changing organizational structures, new technical assignments and alterations in group composition. Despite these dynamic changes, the data reveal consistent results in gatekeeper identification and technical information flows.  相似文献

The ability to communicate appropriately, effectively and persuasively to a diverse audience is a mandated learning outcome for all Australian law students. Communication skills include both written and oral skills. This article examines and evaluates a project aimed at reconceptualising and, thereby, expanding the learning and teaching of oral communication skills in law through the digital presentation of a hypothetical problem using Second Life.  相似文献

The new knowledge (and predictions) created by DNA tests and the family nature of genetic information has already lead to a new problem: the intra-familiar communication of genetic data. This raises questions such as the following. Is there a duty to inform in cases when treatment is possible and the patient does not permit disclosure of genetic results to relatives? Is there an obligation to warn or merely an authorization (that could be used or not)? Could privacy protection be maintain as an individual interest but with some justified violations? A balance needs to be establishes between the interest of privacy and the need to disclose secret information.  相似文献

One of the most significant problems facing environmental law is the dearth of scientific information available to assess the impact of industrial activities on public health and the environment. After documenting the significant gaps in existing information, this Article argues that existing laws both exacerbate and perpetuate this problem. By failing to require actors to assess the potential harm from their activities, and by penalizing them with additional regulation when they do, existing laws fail to counteract actors' natural inclination to remain silent about the harms that they might be causing. Both theory and practice confirm that when the stakes are high, actors not only will resist producing potentially incriminating information but will invest in discrediting public research that suggests their activities are harmful. The Article concludes with specific recommendations about how these perverse incentives for ignorance can be reversed.  相似文献

The recent formation of a United Kingdom and Irish working group, the Body Fluids Forum (BFF), highlighted the need to investigate different working practices prior to any inter-laboratory comparison work and identification of best practice. Various dilutions of semen were seeded onto swabs and cloth samples for each BFF member laboratory to test using their standard techniques. The results showed that the detection of acid phosphatase on swabs is best achieved using direct testing rather than on an extract from the swab. Extraction methods for spermatozoa require a balance to be achieved between using a sufficient volume of water to ensure optimal release and minimal volume to ensure a concentrated extract. PSA tests were investigated and found to be more sensitive than Choline. DNA profiles were obtained from samples in which no spermatozoa had been detected during microscopic examination.  相似文献

Online forms of harassment, stalking and bullying on social network and communication platforms are now arguably wide-spread and subject to regular media coverage. As these provision continue to attract millions of users, generating significant volumes of traffic, regulating abuse and effectively reprimanding those who are involved in it, is a difficult and sometimes impossible task. This article collates information acquired from 22 popular social network and communication platforms in order to identify current regulatory gaps. Terms of service and privacy policies are reviewed to assess existing practices of data retention to evaluate the feasibility of law enforcement officials tracking those whose actions breach the law. For each provision, account sign-up processes are evaluated and policies for retaining Internet Protocol logs and user account information are assessed along with the availability of account preservation orders. Finally, recommendations are offered for improving current approaches to regulating social network crime and online offender tracking.  相似文献

Articles published in seven leading criminology and criminal justice journals were coded with regard to the research methods used, focusing on the general research designs, data-gathering methods, and statistical analysis techniques employed. The results indicated that survey research was by far the dominant mode of acquiring criminological information, that cross-sectional nonexperimental designs still predominated, and that multivariate statistical methods were the norm. The findings could aid criminology and criminal justice faculty in devising graduate methods curricula that reflected the state-of-the-art as currently practiced by criminological researchers.  相似文献

The aim of this study was to determine the comparative accuracy of Demirjian's four dental development methods for forensic age estimation in the Western Australian population. A sample comprising 143 individuals aged 4.6 to 14.5 years were assessed using Demirjian's four methods for dental development (original 7-tooth: M(2), M(1), PM(2), PM(1), C, I(2), and I(1); revised 7-tooth: M(2), M(1), PM(2), PM(1), C, I(2), and I(1); 4-tooth: M(2), M(1), PM(2), and PM(1); and an alternate 4-tooth: M(2), PM(2), PM(1), and I(1)). When comparing all four methods, the 4-tooth method overestimated age in both males and females by 0.04 and 0.25 years, respectively. The original 7-tooth was least accurate for males, while the original 7-tooth, the revised 7-tooth, and the alternate 4-tooth were unsuitable for females. Therefore, we recommend the 4-tooth method to be used for forensic age estimation in Western Australian males and females, as it has the lowest overall mean deviation and the highest accuracy.  相似文献
