The purpose of this study is to identify factors that have led to the emergence of information activities in the global labor force. An analysis of the predominant theoretical perspectives on the development of the information society indicates that a comparison of the development of the information work force in countries that have experienced industrialization under different socioeconomic systems is needed. Finland and Poland are selected as the representatives of a market economy and a centrally planned economy. The results indicate that the information work forces of Finland and Poland have experienced similar patterns of growth over the time period examined. However, the distribution of the work force across different economic sectors differs by socioeconomic system. It is concluded that factors relating to industrialization have played the primary role in the emergence of the information work force and that this emergence may take multiple paths in developing. 相似文献

Statisticians R.A. Fisher and Joseph Berkson have become infamous for ending up on the "wrong" side of the debate over the evidence linking smoking and lung cancer during the 1950s, and scholars have speculated about their personal motives in the controversy. But there were many senior biostatisticians and epidemiologists voicing similar concerns about the quality of the evidence at the time, albeit with less inflammatory rhetoric. This debate occurred during a time when epidemiological research methods commonly used today were understood by few and were only just beginning to work their way into public health and medicine. All of the participants in the debate over smoking and lung cancer saw the need for explicit and rigorous standards for evaluating etiological hypotheses, but they held conflicting views about what those standards should be. The differing opinions on the evidence reflected two different models of etiological research--controlled experiment as the crucial, objective test of a causal hypothesis versus inferential judgment based on a diverse body of evidence. This debate has relevance for current epidemiological practice, as tension between these two views still remains. 相似文献

A dynamic cascade model of development of serious adolescent violence was proposed and tested through prospective inquiry with 754 children (50% male; 43% African American) from 27 schools at 4 geographic sites followed annually from kindergarten through Grade 11 (ages 5–18). Self, parent, teacher, peer, observer, and administrative reports provided data. Partial least squares analyses revealed a cascade of prediction and mediation: An early social context of disadvantage predicts harsh–inconsistent parenting, which predicts social and cognitive deficits, which predicts conduct problem behavior, which predicts elementary school social and academic failure, which predicts parental withdrawal from supervision and monitoring, which predicts deviant peer associations, which ultimately predicts adolescent violence. Findings suggest targets for in‐depth inquiry and preventive intervention. 相似文献

The World Council of Comparative Education Societies (WCCES) has been strongly concerned with intercultural dialogue since the Council was created in 1970. Indeed advancement of education “for international understanding in the interests of peace, intercultural cooperation, mutual respect among peoples and observance of human rights” is one of the goals built into the WCCES Statutes. This paper begins with a focus on the origins and goals of the WCCES, noting in particular links with the mission of UNESCO. The paper then considers dimensions of evolution in the work of the WCCES in the domain of intercultural dialogue. It underlines the growth of the WCCES and the continuing challenges for securing balanced representation of voices and perspectives. 相似文献

A study was conducted comparing the feedback received from students about teaching obtained using different instruments. Twelve first‐ and second‐year undergraduate modules were selected from seven different schools within a single university. Students studying each module were allocated to ‘questionnaire’ and ‘comparator’ groups. ‘Questionnaire’ students completed the standard end‐of‐module questionnaire, whilst ‘comparator’ groups evaluated the modules using ‘rapid feedback’, ‘H form’, focus group and reflective diary methods. The responses of 335 students to questionnaires were compared with those of 160 using the other methods; no results were obtained from the reflective diary students. Only a minority of the issues raised by students using the comparator methods were covered by the questionnaire, and the comparator methods showed different rankings of the issues in common. The key difference between questionnaire and comparator methods was the use of closed and open questions respectively, with comparator methods being more appropriate for formative evaluation. 相似文献

Preferences for pink and blue were tested in children aged 4–11 years in three small-scale societies: Shipibo villages in the Peruvian Amazon, kastom villages in the highlands of Tanna Island, Vanuatu, and BaYaka foragers in the northern Republic of Congo; and compared to children from an Australian global city (total N = 232). No sex differences were found in preference for pink in any of the three societies not influenced by global culture (ds − 0.31–0.23), in contrast to a female preference for pink in the global city (d = 1.24). Results suggest that the pairing of female and pink is a cultural phenomenon and is not driven by an essential preference for pink in girls. 相似文献

Reinstatement after counterconditioning was examined in three experiments with rats. The rats received CS-shock pairings in Phase 1 and then CS-food pairings in Phase 2. When unsignaled shock was presented after appetitive conditioning, fear performance to the CS replaced food performance. This reinstatement effect depended on initial pairings of the CS and shock in Phase 1. It also depended on shock exposure occurring in the test context. The results parallel previous data obtained after extinction. Counterconditioning and extinction yield several parallel effects (spontaneous recovery, renewal, and now reinstatement) which suggest that Phase 2 does not destroy the learning acquired in Phase 1. 相似文献

A causal model for understanding the complex interplay between student‐reported teacher behaviors, student self‐systems, and student engagement was tested. One hundred seventeen African American students in grades 1 through 12 completed a comprehensive questionnaire regarding teacher context, self, and engagement variables. A series of hierarchical regression analyses were conducted to test the hypothesized mediation models and to construct a path model. Most hypotheses were supported. Student self‐system variables (perceived competency and autonomy) mediated relations between teacher context (structure and autonomy support), and engagement. Contrary to predictions, however, teacher involvement exerted a strong and direct effect on student engagement even when controlling for grade level and self‐system variables. Given existing research showing that African American students are at risk for low teacher involvement and that engagement is critical for academic success, research and intervention strategies are urgently needed to promote teacher involvement with these students. © 2002 Wiley Periodicals, Inc. 相似文献

OBJECTIVE: This study seeks to: (1) assess the relationship between identified prenatal substance use and the risk of subsequent maltreatment allegations among families involved with child protective services; and (2) compare the types of safety threats encountered by children whose parents had substance-exposed infant (SEI) allegations to the types of safety threats faced by children whose parents had other types of allegations. METHOD: Survey data from a probability sample of parents were linked to state administrative data over a 33-month time frame. Cox regression models were conducted to assess the relative risk of subsequent allegations associated with parents whose child welfare case opened following an SEI allegation (the SEI group) compared to parents whose case opened following other types of allegations. RESULTS: The likelihood of subsequent allegations is greater among parents in the SEI group. However, the increased risk stems almost entirely from subsequent SEI-related allegations. Parents in the SEI group are not more likely to incur other types of allegations such as physical abuse or lack of supervision. CONCLUSIONS: An increased risk of subsequent maltreatment has been used to justify opening child protective cases on the basis of an SEI allegation alone. By looking closely at the types of subsequent allegations as well as the incidence of subsequent allegations, this research helps to clarify the maltreatment risks associated with SEI cases. 相似文献
