Transferring technology to the small manufacturing firm: A study of technology transfer in three countries     

Thomas J. Allen  Diane B. Hyman  David L. Pinckney 《Research Policy》1983,12(4):199-211

Case histories were compiled of 100 instances of technological change in 102 manufacturing companies in eight industries in Ireland, Spain and Mexico. The cases are analyzed for the source of initial ideas and for sources of technology employed in resolving major problems.Technology is found to flow principally through informal channels within industries. Very little information was obtained from the formal mechanisms or institutions normally considered central to the technology transfer process.Foreign subsidiaries obtain the greatest proportion of their technology from their parent firms. Surprisingly, they are found to have several channels of technology blocked to them, which are more readily available to domestic firms. Domestic firms, in many ways have easier access to foreign technology than do the subsidiaries of multinational firms.Product and process innovations originate in somewhat different quarters. Process innovations are slightly more likely to be based on foreign technology; product innovations are more likely to be based on domestic technology.The results reported in the present paper are very similar in many ways to results reported previously in Brazil and Australia.  相似文献

An Open Letter to Tomorrow's Secondary Teachers     

Jeff Worthy 《Clearing house (Menasha, Wis.)》2016,89(1):18-22

The article takes the form of a letter written to pre-service or beginning teachers at the secondary level in the public school system. The letter acknowledges the attributes they bring to the profession (enthusiasm, optimism, creativity, and open-mindedness) and calls on them to make the most of and work to sustain these traits as they begin their careers. They are then advised in the importance of setting clear expectations for their students, maintaining high standards, and always demonstrating professionalism.  相似文献   

Differences in the relations between antisocial behavior and peer acceptance across contexts and across adolescence     

Kiesner J  Pastore M 《Child development》2005,76(6):1278-1293

This study tests the hypothesis that, during adolescence, antisocial behavior becomes positively associated with peer acceptance. This hypothesis was tested considering both classroom and out-of-class peer relations. Data from a previously published study, with a cross-sectional sample of 577 Italian 11- to 13-year-olds, were used. Analyses showed that in the 6th grade antisocial behavior was negatively related to classroom peer preference, but not significantly related to out-of-class peer inclusion. By the 8th grade, antisocial behavior was positively related to out-of-class peer inclusion, but not significantly related to classroom peer preference. Similar results were found for males and females. The higher level of peer acceptance among the 8th grade antisocial individuals was primarily due to nominations received by other antisocial individuals.  相似文献   

Mighty mouse and MX missiles: Children in a violent society     

Jan Allen  Robert B. Pettit 《Early Childhood Education Journal》1987,15(1):6-9

Ours is a society in which violence, or the threat of violence, is a common experience for many children. Children's fears of the dark, the boogie man, and the headless Horseman have evolved to include fears of Darth Vadar, meltdown, and nuclear war.  相似文献

General population norms about child abuse and neglect and associations with childhood experiences     

Bensley L  Ruggles D  Simmons KW  Harris C  Williams K  Putvin T  Allen M 《Child abuse & neglect》2004,28(12):1321-1337

BACKGROUND: A variety of definitions of child abuse and neglect exist. However, little is known about norms in the general population as to what constitutes child abuse and neglect or how perceived norms may be related to personal experiences. METHODS: We conducted a random-digit-dialed telephone survey of 504 Washington State adults. Respondents were asked whether they believed each of 34 behaviors, identified in focus groups as possibly physically, sexually or emotionally abusive or neglectful, constituted abuse or neglect. Then, they were asked whether they had experienced 33 of the behaviors. RESULTS: Five of the six behaviors with the highest levels of consensus were for sexual abuse, whereas only one emotionally abusive behavior had a high level of consensus (95% agreement). Consensus that spanking constituted abuse increased with severity. Those respondents who reported experiencing a particular behavior were significantly less likely to believe the behavior abusive for 11 of the 33 behaviors and more likely to believe the behavior abusive for two of the behaviors. Where comparisons were possible, there was a high level of consensus that behaviors identified as abusive in Child Protective Service operational definitions constituted abuse. CONCLUSIONS: Self-reported childhood experiences were associated with perceived norms about child abuse. A better understanding of community norms about child abuse and neglect may be helpful in communicating with the public or allow for better targeting of educational messages through the media, parenting education classes, and so forth.  相似文献   

Tutoring deaf students in higher education: a comparison of baccalaureate and sub-baccalaureate student perceptions     

Lang HG  Biser E  Mousley K  Orlando R  Porter J 《Journal of deaf studies and deaf education》2004,9(2):189-201

Seventy-three deaf college students completed a survey examining perceptions about tutoring outcomes and emphases, characteristics of tutors, and responsibilities associated with learning through tutoring. The comparisons revealed that while baccalaureate and sub-baccalaureate students have many similar perceptions about tutoring, there are also some striking differences. In particular, as compared to the sub-baccalaureate students, baccalaureate students have a stronger preference for focusing on course content and for working with tutors who actively involve them during the tutoring sessions. In addition, baccalaureate students prefer to decide the focus of the tutoring themselves while sub-baccalaureate students tend to leave the decision to the tutor. The results of the analyses with three scales measuring perceptions of tutoring dimensions are summarized and recommendations for the selection and preparation of tutors, as well as for future research, are provided.  相似文献
