Internal sequential innovations: How does interrelatedness affect patent renewal?   总被引：1，自引：0，他引：1  

Kun Liu  Jonathan Arthurs  John Cullen  Roger Alexander 《Research Policy》2008,37(5):946-953

The value of patented innovations has attracted substantial research attention, especially in the context of patent renewal. However, research often assumes that a firm's patented innovations are independent from each other. We draw upon evolutionary economics and suggest that some of a firm's patents share important genealogical relationships, which we refer to as internal sequential innovations. We propose internal sequential innovations are more valuable and therefore more likely to be renewed than stand-alone innovations. We examine our hypotheses from a dataset of US pharmaceutical and biotechnology patents. The results confirm our hypotheses at both the patent and the firm levels.  相似文献

Studying and Teaching White‐Collar Crime: Populist and Patrician Perspectives     

Neal Shover  Francis T. Cullen 《Journal of Criminal Justice Education》2013,24(2):155-174

White‐collar crime is both an integral part of undergraduate criminology courses and textbooks and the subject of enduring analytic controversy. Much of the latter can be traced to two conflicting but unrecognized conceptual paradigms employed by investigators and teachers when they examine white‐collar crime: Populist and Patrician. These perspectives differ in definitional approach to the concept, explicit recognition of the criminality of offenses committed by respectable citizens, how much attention is paid to the victims and costs of white‐collar crime, the analytic centrality of criminalization, and the variables and dynamics that purportedly explain variation in offending. Preference for one or the other analytic paradigm to some extent is predictable on the basis of a scholar’s educational background, type of institutional placement and disciplinary training. Explicit acknowledgment and pedagogical use of conflicting paradigms hold the potential to enhance students’ ability to think critically about white‐collar crime. It also makes clear that the disagreements that plague this area of inquiry are deeply rooted and thus are unlikely to be resolved soon.  相似文献

Considerations for Integrating Technology in Developing Communities in Latin America     

Daniela Núñez Ponte  Theresa A. Cullen 《TechTrends》2013,57(6):73-80

This article discusses issues related to introducing new information and communication technologies (ICT) into Latin American countries. Latin American countries are gaining world focus with political changes such as the death of Hugo Chavez in Venezuela and the election of the first Latin American Pope. This region will host the World Cup, Olympics and IMF World Bank annual meetings in the next 5 years; meanwhile they are projected to continueto experience moderate economic growth (IMF Survey, 2013). We suggest that successful innovation may be achieved through a combination of fundamental concepts of change with a culturally sensitive approach. This article discusses general concerns related to the diffusion of new technologies, the importance of cultural context, and the organization needed within the community for success. The literature review is based three assertions the characteristics of the native culture, general concerns of innovation for new technologies, and the context and organization needed by the community. We assert that to have successful integration of ICTs, innovators must understand the needs of the individuals who will use the innovation, as well as, the key factors that influence the culture, stakeholders, and common goals of the community and employ a strategy that utilizes industry, government and educators to produce lasting change.  相似文献   

Effects of Third Age Learning Programs on the Life Satisfaction,Self-Esteem,and Depression Level among a Select Group of Community Dwelling Filipino Elderly     

Rowena L. Escolar Chua 《Educational gerontology》2013,39(2):77-90

With the growing number of older adults becoming a global concern, many countries have focused on education as a means of promoting successful aging. Although third age learning is gaining substantial ground in other countries, it is not well-established in the Philippines. The overall intent of this experimental study was to assess the effectiveness of community-based third age learning programs on the life satisfaction, self-esteem, and level of depression of a select group of Filipino elderly in a community setting. A pre- posttest study design was used on 40 community dwelling Filipino elderly who were randomly assigned to either the experimental or control group. Both groups accomplished the Life Satisfaction Index for the Third Age Short Form (LSITA-SF), Rosenberg's Self-esteem Scale (RSES), and the Geriatric Depression Scale (GDS). The experimental group was exposed to a four-month program consisting of wellness, physical fitness, and livelihood training activities facilitated by volunteer faculty from a local university; the control group received no intervention. The results of t tests showed statistically significant group differences between the experimental and control group, with the former posting higher life satisfaction, self-esteem, and lower depression level compared to the control group. Findings of this study add to the knowledge base that active participation in third age learning programs—which include opportunities for physical activity, cognitive learning, recreation, and social interaction—can improve the psychological and psychosocial health of an older adult.  相似文献   

Using the Case Method to Introduce Information Skill Development in the MBA Curriculum     

Ann Cullen 《Journal of Business & Finance Librarianship》2013,18(3):208-232

Effective use of information is a key component of the manager's job. In a business environment burdened by information overload, the question for MBA programs is how to provide instruction so their graduates have the necessary foundations in this skill. Business managers use information during the decision-making process, so students need to learn about and build the capabilities to use information effectively. Many information professionals at business schools have been investigating ways to effectively impart these skills. The instruction described, using the case method and coteaching with a faculty member to introduce information skill development, adds to this work.  相似文献   

Genetic research and genetic information: a health information professional's perspective on the benefits and risks     

Cullen R  Marshall S 《Health information and libraries journal》2006,23(4):275-282

BACKGROUND: The completion of the Human Genome Project, and recent breakthroughs in identifying the genes both directly responsible for and contributing to the severity of specific diseases and disabilities in humans offer great potential for future health care. AIM: The aim of the paper is to inform the health information community of these developments in order to foster debate over their wide-reaching implications. METHODS: The article outlines recent research in this area and explains how our growing understanding opens the way for improved diagnosis of disease, detection of possible predisposition to specific diseases, the interaction between genetics and environmental aspects such as diet, as well as enabling gene therapy and preventative actions. This new knowledge also opens the way for the use of pharmacogenetic information to enhance the efficacy of pharmaceuticals and to avoid toxic reactions. RESULTS: These advances have significant social, legal and ethical implications. Most countries have limited legislative control over the use and protection of genetic information about individuals. CONCLUSION: There is a role for health information professionals to play in promoting wider public knowledge of genetic research and its implications, in fostering public debate on key issues, and in seeking clearer policies in the health sector concerning the use of genetic information about individuals.  相似文献   

Experienced Teachers’ Strategies for Assessing Nature of Science Conceptions in the Elementary Classroom     

Valarie L. Akerson  Theresa A. Cullen  Deborah L. Hanson 《Journal of Science Teacher Education》2010,21(6):723-745

This study explored the nature of science (NOS) assessments K-4 classroom teachers developed for measuring students’ understandings of NOS elements. We used the Views of Nature of Science Questionnaire-Form VNOS-D2 (Views of Nature of Science Elementary School Version 2) and interviews to verify that teachers’ conceptions of NOS were sufficient to enable them to teach and assess NOS. We collected copies of teachers’ action research designs, lesson plans, and assessment tools, conducted classroom observations and made field notes of their science instruction and assessments. We videotaped conversations at monthly workshops to note discussion surrounding teaching and assessing NOS in K-4 classrooms. We found that experienced teachers designed a variety of strategies for assessing NOS conceptions that differed by grade level.  相似文献
