Few studies have moved beyond the dyadic level of an ongoing alliance and examined factors contributing to the success of entering a series of alliances. In this paper we expect biotechnology firms over time to learn from their alliance experience and to develop general alliance capabilities. Specifically, we expect the speed with which they enter into new research alliances, e.g. their alliance formation rate, to be affected by capabilities built up in prior alliances as well as by characteristics of their partners. We use longitudinal event history data for the complete population of US biotechnology firms for 1973–1999 to test four hypotheses about factors affecting the rate of new alliance formation. Our analysis suggests that the speed of entering research alliances is affected by prior experience of the focal firm, but not by partner characteristics. Our findings provide evidence that biotech firms learn how to learn more effectively from multiple research alliances; however, this effect is generalized and not tied to specific characteristics of the alliance partner. 相似文献

本文应用Oaxaca-Blinder分解方法,把垄断行业高收入分解为合理和不合理两个部分。实证分析发现,垄断行业与竞争行业之间收入差距的50%以上是不合理的。这主要是行业的垄断造成的。由于目前收入统计未能反映垄断行业的高福利,以上测量结果显然低估了垄断行业高收入中的不合理部分。 相似文献

Abstract Objective: Determine the effects of a short-term, multi-faceted, point-of-selection intervention on college students’ perceptions and selection of 10 targeted healthful foods in a university dining hall and changes in their self-reported overall eating behaviors. Participants: 104 college students, (age 18–23) completed pre-I and post-I surveys. Methods: Pre-survey collected at dining hall in April 2007, followed by 3-week intervention then post-survey collected via email. Healthy choice indicators, large signs, table tents, flyers and colorful photographs with “benefit-based messages” promoted targeted foods. Response rate to both surveys was 38%. Results: Significantly more participants reported that healthful choices were clearly identified in the dining hall after the intervention. Over 20% of participants reported becoming more aware of healthful food choices in the dining hall after the intervention. Significant increases in self-reported intake were reported for cottage cheese and low-fat salad dressing, with a trend toward increased consumption of fresh fruit. Seven of the 14 assessed eating behaviors had significant changes in the desired direction. Increased awareness of healthful foods was the top reason for self-reported changes in overall eating behaviors. Conclusion: Short-term, multi-faceted, point-of-selection marketing of healthful foods in university dining halls may be beneficial for improving college students’ perceptions and selections of targeted healthful foods in the dining hall and may improve overall eating behaviors of college students. 相似文献

Abstract An assessment of the prevalence and scope of nutrition services offered through 208 randomly selected American College Health Association member student health centers revealed that 79% of the 160 respondents provided some type of nutrition education for students. One-to-one counseling, available at 96% of the institutions, was the most common approach. The larger the school's enrollment, the more likely it was to provide programs in nutrition. All of the institutions with student populations of more than 35,000 offered some type of nutrition service, as did 52% of the 19 schools with enrollments between 2,000 and 5,000. Health educators, nurses, doctors, dietitians, and trained peer educators provided the services, with registered dietitians the most common providers and often coordinators of the programs. Costs to students for nutrition interventions were nominal; weightmanagement programs were the most expensive and showed the greatest variation in content. 相似文献

Abstract Objective: This article examines students’ perceptions of individual and institutional responsibility for sexual health so that institutions can better provide for the needs of their students to increase academic success and healthy relationship outcomes. Participants: Students from 2- and 4-year colleges in 1 state (N = 78). Methods: From May through November 2010, the authors used go-along interviews to examine students’ perceptions of resources for sexual health on their campuses. Results: Participants believed that it is the college's responsibility to provide resources and the responsibility of students to access resources. Participants at 2-year schools wanted referrals to resources, whereas participants at 4-year schools expected resources to be available and emphasized the importance of a supportive community. Conclusions: Students at 2- and 4-year colleges have different expectations of their institutions; by making resources and referrals for sexual health available, colleges can better serve their students, which will result in improved health outcomes. 相似文献

Past research has examined links among animal abuse, child maltreatment, and intimate partner violence and demonstrated the importance of addressing the needs of both human and animal victims. We hypothesized that there might be a similar link between animal abuse and older adult welfare issues. As a first step in the earlier research was the development of a screening protocol that shed light on the link between domestic violence and animal abuse, we decided to follow a similar route to explore this new topic by asking state government representatives about their experiences, if any, with this topic. Here we report the results of a national survey of state Adult Protective Services agencies regarding their protocols for assessing animal welfare issues in the context of older adult maltreatment. We also describe a model assessment protocol we developed in collaboration with the Utah Division of Aging and Adult Services. 相似文献

This study was designed to explore how organizational life in university-affiliated graduate social work education programs in the United States is affected by the stress of heightened caregiving roles. Analysis of data from 69 schools demonstrated deleterious effects of caregiving stress on organizational effectiveness, including missed obligations, feeling overwhelmed, and distracting others by seeking social support for specific problems. The authors identify two variables that provided partial amelioration of caregiver stress and appeared to contribute to increased organizational effectiveness: larger faculty size and on-site child care. 相似文献

ABSTRACT Six focus groups were convened to collect data on successful interdisciplinary community collaboration (ICC) strategies. Participants came from a variety of disciplines but shared the common identification of having worked in similar communities. Participant assignment to one of six groups was designed to insure diversity by gender and race or ethnicity. They discussed four questions received in advance. Prior consented tape-recorded sessions were transcribed and reviewed by group facilitators using a process of member checking. Data analysis utilized the qualitative methodology known as grounded theory. Results indicate that organizers must have (1) a knowledge base of strategic planning, management, and administration, (2) an intra- or interpersonal skills set, and (3) well-defined values and attributes. The Practice implications are that further research is needed to more fully explore the complexity of ICC work. 相似文献

Findings from previous research (Coakley, Halone, & Wolvin, 1996; Halone, Wolvin, & Coakley, 1997; Wolvin, Coakley, & Halone, 1995) indicate that the listening process may be conceptualized primarily in (a) cognitive, (b) affective, (c) behavioral/verbal, (d) behavioral/nonverbal, and (e) behavioral/interactive terms. This report seeks to quantitatively confirm these qualitatively-derived findings. Specifically, this study sought to analyze whether each respective dimension could be generally characteristic of the listening process. Confirmatory factor analyses were conducted, providing support for each respective dimension. Results from this study have implications for how communication scholars should conceive of the listening process in theoretical, empirical, and pedagogical terms. 相似文献
