In recent years, several computer programs for dental identification in mass disasters have been developed. Unfortunately, it may be difficult to get access to such programs. The Norwegian police presently utilizes a text retrieval program, NOVA1STATUS, for detection work. This program is based on the British STATUS ONE program, and it enables the user to find from a large pool of postmortem dental registration one or several sets containing specific information about one tooth or several teeth. The complete relevant set(s) can be displayed for visual examination and comparison. A coding system for dental information has been developed as well as a system for interrogating the computer. This system and its efficiency have been tested on a simulated small scale disaster where various well-known difficulties in dental identification were included.  相似文献

We study the rationale for the use of exclusivity to protect transfer of technology in subcontracting agreements. The legal possibility arises through the EU Notice on Subcontracting. Empirically, the link between exclusive agreements and technology transfer among firms in the automotive supply industry in EU candidate countries is surprisingly weak, although with exclusive-supply or exclusive-buying clauses in subcontracting agreements upstream transfer of technology is more likely. Exclusive agreements are often reciprocal, and are typically passed on. Downstream firms are more likely to face and use vertical restraints. Technology trickles upstream: Multinational final assemblers transfer more technology than lower-tier suppliers.  相似文献

Failure to solve problems related to parenting and other aspects of daily living is hypothesized to result in frustration or inability to cope, and lead to deviant parental behavior such as aggression or neglect. The present investigation provided support for a procedure for measuring parental problem-solving skill and compared the problem-solving abilities and child behavior problems of maltreating and nonmaltreating parents. Subjects were 40 parents with at least one child between the ages of three and twelve. Subjects were assigned to one of four groups: (a) physically abusive parents (n = 9); (b) neglectful parents (n = 9); (c) nonmaltreating clinic parents seeking help for child behavior problems (n = 11); and (d) nonmaltreating, non-help-seeking community parents (n = 11). Abusive and neglectful parents were deficient in problem-solving skill as compared to clinic and community parents, yet there were many similarities in parental reports of child behavior problems for maltreating and nonmaltreating parents. Parental problem-solving skill did not correlate significantly with parental ratings of child behavior problems.  相似文献

Inability to solve problems related to parenting and other aspects of daily living is hypothesized to result in frustration or inability to cope, and contribute to the occurrence of problematic parental behavior such as physical abuse or neglect. The present investigation evaluated the Parental Problem-Solving Measure (PPSM), a procedure for measuring parental problem-solving skill of maltreating and nonmaltreating parents. Subjects were 60 parents with at least one child between the ages of 2 and 12. Subjects belonged to one of three groups: (a) physically abusive and/or neglectful parents (n=27); (b) nonmaltreating clinic parents seeking help for child behavior problems (n=12); and (c) nonmaltreating, non-help-seeking community parents (n=21). Results demonstrated the interrater reliability, internal consistency, and temporal stability of the PPSM and its five subscales. Support is also provided for the convergent and discriminant validity of the measure.  相似文献
