In a North‐South model with endogenous foreign direct investment (FDI), we examine the impact of Southern intellectual property rights (IPR) protection on the mode and industrial composition of international technology transfer. A novel feature of the model is that, due to technological reasons, industries differ with respect to their susceptibility to imitation. In equilibrium, licensing occurs in industries where the risk of imitation is low and FDI where it is of intermediate magnitude. Stronger IPRs in the South (1) alter the industrial composition of multinational activity toward licensing at the expense of FDI; (2) reduce local imitation; and (3) increase licensing and, to a lesser extent, FDI.

This 2½‐year, 5‐wave longitudinal study tests the hypothesis that acculturation discrepancies between Hispanic immigrant parents and adolescents would lead to compromised family functioning, which would then lead to problematic adolescent outcomes. Recent‐immigrant Hispanic parent–adolescent dyads (N = 302) completed measures of acculturation and family functioning. Adolescents completed measures of positive youth development, depressive symptoms, problem behavior, and substance use. Results indicated that Time 1 discrepancies in Hispanic culture retention, and linear trajectories in some of these discrepancies, negatively predicted adolescent positive youth development, and positively predicted adolescent depressive symptoms and binge drinking, indirectly through adolescent‐reported family functioning. The vast majority of effects were mediated rather than direct, supporting the acculturation discrepancy hypothesis. Implications for further research and intervention are discussed. 相似文献

Items assessing financial motives were recently integrated with the Gambling Motives Questionnaire (GMQ), resulting in a revised measure that assesses coping, enhancement, social and financial motives for gambling (GMQ-F). The aim of this research was to test the proposed four-factor structure of the GMQ-F, determine if GMQ-F responses were invariant across sex, and test a structural model that specifies links between motives, gambling frequency and problem gambling severity. Telephone surveys were conducted with 932 adult gamblers from across Manitoba, Canada, who responded to items from the GMQ-F and reported their frequency of gambling and levels of problem gambling severity. Confirmatory factor analysis yielded strong support for the four-factor structure of GMQ-F scores, and invariance testing provided evidence of measurement invariance across sex. Finally, support was found for the hypothesized structural model in which each gambling motive predicted gambling frequency, which in turn predicted problem gambling severity. Coping motives also directly predicted problem gambling severity. These results provide strong evidence in support of the validity of GMQ-F responses, offer further support for the integration of financial motives with the GMQ, and delineate relationships between gambling motives, gambling frequency and gambling-related harm. 相似文献

We calculate the Lebesgue–measures of the stability sets of Nash-equilibria in pure coordination games. The results allow us to observe that the ordering induced by the Lebesgue–measure of stability sets upon strict Nash-equilibria does not necessarily agree with the ordering induced by risk–dominance. Accordingly, an equilibrium selection theory based on the Lebesgue–measure of stability sets would be necessarily different from one which uses the Nash-property as a point of orientation. 相似文献

Summary Four hundred people who came to a hospital casualty departmentduring one year after taking an overdose were randomly assignedto an experimental task-centred casework service or to the routineaftercare service. Half the sample was followed up four monthsafter overdose and the remainder 18 months after it. Clientsin the experimental group were more satisfied with the servicethey had received and showed more immediate improvement in socialproblems. A task-centred method (agreement on target problems,work on tasks and adherence to a time-limit) proved feasiblein about half the experimental cases. 相似文献

Purpose: To investigate a possible relation between penile Doppler ultrasound examination (PDUE) parameters and efficacy of chronic therapy with tadalafil (TAD) combined with a protocol of aerobic physical activity (PA) in patients with late onset hypogonadism (LOH). Methods: The study evaluated 30 patients consecutively enrolled with LOH and erectile dysfunction which present contraindication to hormonal replacement therapy for concomitant prostate disease. These patients were subjected to a combined protocol with phosphodiesterase V selective inhibitors (TAD 5?mg daily) and aerobic PA.Results: After three months, we observed significant improvements in erectile function [IIEF-5, median (IQR)?=?13.0 (7.0–18.0) versus 6.0 (5.0–6.75); p?0.01] and of the main metabolic [homeostatic model assessment index, median (IQR)?=?2.5 (1.62–3.37) versus 3.0 (2.0–3.75); p?0.01; body mass index, median (IQR)?=?27.0 (24.0–28.75) versus 27.5 (24.0–29.5)] and vascular parameters [peak systolic velocity, median (IQR)?=?29.5 (24.25–31.0) versus 28.0 (23.0–24.25); acceleration time, median (IQR)?=?114 (105.25–134.0) versus 115.0 (106.5–134.0)], assessed by PDUE.Conclusion: PA in association with phosphodiesterase V inhibitors could compensate the effects of hypogonadism on erectile function and facilitate the clinical response to these drugs even in the absence of adequate serum concentrations of total testosterone. 相似文献
