150 Years of Patent Office Practice 总被引:2,自引:0,他引:2
This article examines the administrative practices of the patentoffices in 60 countries over a 150-year period, a little exploredarena where government bodies and private firms interact. Largerand wealthier countries where international trade is more importantgive patent applicants more options. In these nations, patentoffice administrators flexibility is often restrictedand the responsibility for determining patentability dividedbetween the patent office and the courts. Civil law nationstend to rely solely on the courts to determine patent validityand restrict the discretion of patent office administrators.They also tend to offer patent applicants more options. 相似文献

Hopeful expectations for the future have been shown to play an important role in the positive development of youth, including youth contributions to society. Although theory and some research suggest that familial socialization may influence future-oriented cognitions, little work has focused on the possible interrelation of parent–child relationships and the development of hope, particularly during adolescence. Accordingly, the first goal of this study was to identify developmental profiles of youth with respect to hopeful future expectations (HFE) and parental trust across adolescence. Next, we explored whether these developmental trajectories were related to youth Contribution, indexed by community leadership, service, and helping attitudes and behaviors. We used growth mixture modeling to simultaneously examine trajectories of adolescents’ perceived connections with parents (indexed by parent trust) and HFE among 1,432 participants (59 % female) from Waves 3 through 6 (Grades 7 through 10) of the 4-H Study of Positive Youth Development. A four-profile model provided the best fit to the data, with the following profiles: Moderate HFE/U-shaped Trust; Moderate HFE/Increasing Trust; Both Decreasing; and Both High Stable profiles. We then explored whether hope-trust profiles were related to youth Contribution in Wave 7. Contrary to hypotheses, results indicated that the profile reflecting the greatest discrepancy in HFE and trust across early to middle adolescence (i.e., Moderate Hope/U-shaped Trust) was associated with the highest mean Contribution scores. The implications of the findings for future theory and research are discussed. 相似文献

The impact of the cardinal relationships amongpecuniary payoffs, and of social history and reputation, on thechoice of strategies in four one-shot Prisoner's Dilemma games isexperimentally examined. The results suggest that normalized payoffvalues linked to ``fear'' and ``greed'' are important as predictorsof behavior in the PD games. Success in coordinating on the payoffdominant equilibrium in previous plays of coordination games alsoincreases the probability of cooperative play in the PD games. Theeffect of past play is strongest when individuals are matchedrepeatedly with the same person in previous play, as contrasted tobeing matched randomly with another player. 相似文献

Although the role of school engagement in influencing children’s academic competence has been recognized in past theory and
research, how school engagement may mediate the relationships between ecological and personal resources and academic competence
remains largely unknown. Using structural equation modeling procedures, the present study was aimed at examining the role
of school engagement in mediating the associations between ecological and personal assets and academic competence. Data from
960 participants (45.6% boys) who took part in the Grades 5 and 6 assessments of the longitudinal, 4-H Study of Positive Youth
Development were used. Evidence was found for a model positing two distinct school engagement components, Behavioral and Emotional,
and for the role of these facets of school engagement in the relationships between developmental assets and later academic
competence. Personal and ecological assets had indirect effects on later academic competence, via behavioral and emotional
school engagement. Behavioral and emotional school engagement predicted academic competence differently. Emotional engagement
was indirectly linked to academic competence, via behavioral engagement. Behavioral and emotional engagement also had different
individual and contextual antecedents. Implications of the findings for evaluating the role of behavioral and/or emotional
school engagement in academic competence and positive youth development are discussed. 相似文献

Crowding out Citizenship 总被引:1,自引:0,他引:1
Elinor Ostrom 《Scandinavian political studies》2000,23(1):3-16
The currently accepted theory of collective action presumes that individuals are helplessly trapped in social dilemmas. This has led to a form of policy analysis that presumes external authorities must solve all collective-action problems. The presumed universal need for externally implemented incentives is based, however, on a single model of rational behavior. This model has been shown to be an inadequate foundation to explain extensive empirical findings from the field and the experimental laboratory related to nonmarket settings. Thus, it is necessary to adopt a broader theory of human behavior that posits multiple types of individuals – including rational egoists as well as conditional cooperators – and examines how the contexts of collective action affect the mix of individuals involved. I will briefly review the empirical evidence related to intrinsic motivations and how external incentives may crowd out or crowd in behaviors that are based on intrinsic preferences. I then discuss the delicate problem of designing institutions that enhance citizenship rather than crowding it out. The penchant for neat, orderly hierarchical systems needs to be replaced with a recognition that complex, polycentric systems are needed to cope effectively with complex problems of modern life and to give all citizens a more effective role in the governance of democratic societies. 相似文献

Most proposals for changing the organization of police serving metropolitan areas are presented without any evidence concerning the effectiveness of differently organized police departments in serving urban areas. Assertions are simply made that large scale police departments are more effective and more efficient. This paper attempts first to define the concepts of output and efficiency for police agencies. Secondly, it attempts to develop some potential measures of output and efficiency which could be used in evaluating the comparative output and efficiency of differently organized police departments serving metropolitan areas. A simplified scheme is presented which divides police activities into four types and discusses the problems of measurement for each type. The problems of measuring output and efficiency become more and more difficult as one moves from the first through the fourth type of police activity. While extensive difficulties are present in any attempt to measure the output and efficiency of police agencies, such efforts must be undertaken in order to evaluate the success of past reforms and to be able to predict future successes or failures with higher degrees of accuracy. Without serious attempts to evaluate the consequences of reform, future changes may produce more harm than good. 相似文献
