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

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

Callous–unemotional (CU) traits in adolescent boys and response to teacher reward and discipline strategies     

Jennifer L. Allen  Amy Morris  Celine Y. Chhoa 《Emotional and Behavioural Difficulties》2016,21(3):329-342

The aim of this study was to investigate the relationship between callous–unemotional (CU) traits and response to rewards and discipline in adolescent boys using a mixed-methods approach. Participants comprised 39 boys aged between 12 and 13 years and 8 teachers. Quantitative findings showed that CU traits were significantly related to punishment insensitivity, controlling for conduct problems, autism symptoms and hyperactivity. In contrast, there was no significant association between CU traits and reward sensitivity. Qualitative analysis indicated that teachers view children high in CU traits as responsive to fewer reward and discipline strategies, and strategies need to be implemented and monitored with care to avoid unintended, undesirable outcomes. However, time out, praise, support from other staff and maintaining a positive teacher–child relationship were identified as effective strategies. Findings emphasise the need to carefully select, modify and implement existing evidence-based classroom behaviour-management strategies with high-CU children.  相似文献
