In recent yems, rapid growth hm occurred in both the number and diversity of university-industry progrmns in the United States. While little comprehensive assessment of these programs exists to date, this paper argues that a systematic empirical analysis of a cmpany's perception of universities as knowledge sources is critical toa clear understanding of the newallknces between industry and academia. From a survey of216 companies, a pattern emerges where the sources of technical knowledge perceived as important by industry are complex and highly interrelated, and they also vary according to the characteristics of companies, especially size. It is seen that university research rather than universities as institutions per se are critical ingredients to the development of new products and production processes.  相似文献

Abstract: The Norman Wells project involved a tenfold expansion of the Norman Wells oilfield and construction of a 324-mm (12-inch) pipeline extending 870 kilometres up the Mackenzie Valley to northern Alberta. Completed in May 1985 after years of controversy, Norman Wells expansion was the first of several large hydrocarbon production and transportation projects likely to be completed in the Mackenzie Valley by the end of the century. Because of a highly innovative approach to project management, Norman Wells has been heralded as a model for future northern development projects. Construction was delayed seventeen months from the time of project approval in part to permit effective planning and the use of “special measures” during the construction phase. A major component of these special measures was the unique Norman Wells impact funding program set up to help manage negative effects and enable native involvement in the project. This paper assesses the planning and administration of two socioeconomic components of the impact funding program, using seven criteria drawn from the literature on socioeconomic monitoring and management. The subject programs failed to satisfy all but one criterion. Indeed, the administrative mechanisms used proved to be an serious impediment to effective socioeconomic impact management. This failure was rooted both in the politics of the impact funding package itself and in the historical modus operandi of the federal government, particularly the Department of Indian Affairs and Northern Development, in the north. Sommaire: Le project Norman Wells comprenait l'expansion en 10 volets du champ pétrolifère du même nom et la construction d'un oléoduc de 324 mm de diamètre, s'étendant sur 870 kilomètres le long de la vallée Mackenzie jusqu'au nord de 1'Alberta. Ce projet, qui a été terminé en mai 1985 après des années de polémique, était le premier de plusieurs grands projets dans le secteur de la production et de l'acheminement des hydrocarbures à avoir toutes les chances d'être fini dans la valée du Mackenzie avant la fin du siècle. En raison de la façon tout à fait nouvelle dont a été abordée sa gestion, on a dit du projet Norman Wells qu'il servirait à l'avenir de modèle aux projets de développement dans le Nord. La construction n'a débuté que 17 mois après que le projet a été approuvé en partie . pour permettre une planification efficace de façon que des mesures spéciales. soient appliquées pendant la construction. (mainc 1981:4). Un des éléments importants des mesures spéciales était le programme de financement à fort impact Norman Wells, tout à fait unique, mis sur pied dans le but de gérer les effets négatifs et de permettre aux autochtones de participer au projet. Dans cet article, on évalue la planification et l'administration de deux éléments socio-économiques du programme de financement à fort impact en s'appuyant sur sept normes tirées des documents scientifiques portant sur la surveillance et la gestion dans le domaine socio-économique. Les programmes ont échoué dans tous les domaines, sauf un. En effet, les mécanismes administratifs auxquels on a eu recours ont été un sérieux handicap pour gérer le projet de façon efficace d'un point de vue socio-économique. Cet échec plonge ses racines à la fois dans la politique qui sous-tendait le programme de financement à fort impact et dans le modus operandi de toujours du gouvernement fédéral dans le Nord, en particulier celui du mainc.  相似文献

This study examined the in vitro stability of 6-acetylmorphine (6AM) in horse blood, sheep vitreous humour (VH) and homogenised deer muscle stored under different storage conditions. The stability of 6AM in horse blood is of interest because many toxicological laboratories utilise this matrix for the preparation of blood calibration and check standards and the latter are typically stored during routine use. Data on the storage stability of 6AM in human VH is extremely limited and no data has been reported in muscle. In the absence of human samples, 6AM stability was demonstrated in sheep vitreous and deer muscle. Blood and VH were stored with and without NaF at room temperature (RT), 4 and -18°C for 84 days. Muscle tissue homogenates were prepared in water with and without NaF and also in phosphate buffer (pH 6.0) containing NaF. Homogenates were stored for 31 days at RT, 4 and -18°C. Morphine and 6AM were extracted using SPE and quantified by GC-ion trap-MS/MS. In the absence of NaF, 6AM could not be detected after 7 and 14 days in blood stored at RT and 4°C, respectively. Although at -18°C 6AM was stable for 7 days (12% loss), only 54% was detected by day 84. The addition of NaF to horse blood increased 6AM stability substantially at every temperature. Further, the rate of degradation was found to be significantly slower in blood preserved with 2% NaF compared with 1% NaF (p=.05). 6AM was stable for the study period in preserved blood (1 and 2% NaF) stored at -18°C. For laboratories utilising horse blood in the preparation of standards, preservation with 1% NaF (minimum) and storage at -18°C is recommended. The addition of NaF to VH was essential for 6AM stability. Irrespective of temperature substantial losses (≥ 42%) were observed in unpreserved sheep VH by day 7. In preserved VH the concentration declined by only 22% on day 7 following storage at RT and no loss observed in VH stored at 4 and -18°C at the same time. In muscle, 6AM was stable for 7 days in preserved samples stored at RT and in all samples stored at 4°C and below. The addition of NaF increased the stability of 6AM substantially in muscle. The increased stability of 6AM in VH and muscle preserved with fluoride was attributed to inhibition of bacterial action and the subsequent reduction in the rate of putrefaction of these tissues.  相似文献

Criminologists have long recognized the importance of peers in the etiology of delinquency. Yet, the bulk of empirical studies on this topic make the implicit assumption that the peer effect to be conditioned is linear. With few notable exceptions, prior criminological research has not thought deeply about possible nonlinearity in the peer effect. To address this issue, the present study examines whether the functional form of the relationship between peer and respondent smoking, getting drunk, and fighting is nonlinear, and whether this nonlinearity is moderated by lagged respondent delinquency. Logistic regression models on adolescents from The National Longitudinal Study of Adolescent Health indicate that the marginal effect of peer delinquency on respondent delinquency decreases as the count of delinquent friends increases, consistent with a satiation effect. Moreover, the models indicate that the nonlinear effect of peer delinquency on respondent delinquency is moderated by prior respondent delinquency.  相似文献

In considering psychiatric evidence, criminal justice systems make considerable use of labels from official psychiatric classificatory systems. There are legislated requirements for psychological and/or behavioural phenomena to be addressed in legal tests, however medico-legal use of the current categorical diagnostic frameworks which are increasingly complex is difficult to justify. The lack of validity in large domains of the present classificatory systems is now more openly acknowledged, prompting a critical rethink. Illustrative examples include post-traumatic stress disorder, various personality disorders, and dissociative identity disorder. It follows that the Courts' faith in the present categorical classifications (e.g., DSMIV and ICD10) is misplaced and may be ultimately unhelpful to the administration of justice.  相似文献
