Adolescence is perhaps the most difficult period of child rearing for parents. This study attempted to identify disciplinary techniques used by parents as perceived by mothers, fathers, and their adolescent children. Results indicated several significant areas of intrafamilial disagreement in regard to disciplinary techniques utilized, although all subjects tended to agree that some form of verbal reasoning was the primary disciplinary technique utilized with these adolescents.This study was funded, in part, by the Ohio Agricultural Research and Development Center (H-644) and the School of Home Economics, The University of Georgia.Received his Ph.D. in child and family studies from the University of Tennessee. Current interests include adolescent development, family influences on sex-role development, and dual-work families.Received her Ph.D. in sociology from Iowa State University. Major interests include family research methodology, assessment of family power, and marital dissolution.Received her Ph.D. in educational psychology from the University of Texas. Current research interests include parenting, sex roles, and socialization across the life-span. 相似文献

This study was divided into two parts. The first part consisted of an investigation of the frequency of television viewing among a sample of 2302 15-year-olds in 12 comprehensive schools. Subjects were divided into two groups, high and low frequency viewers, according to their own estimate of viewing time. The general picture which emerged (with some overlap of scores) was that high frequency viewers tended to be more neurotic and introverted; less intelligent; had less favorable attitudes to school; were less likely to think sport was important; were more likely to be bored in their leisure time; and possessed different social attitudes than low frequency viewers. The second part of the study investigated the program preferences of a subsample of over 900 subjects drawn from the main study. Little difference was found in the program preferences of high and low frequency viewers, but clear differences of preference were found between the sexes.Received his Ph.D. from the University of Aberdeen. Main research interests include social factors influencing education, adolescence, sports psychology, community education, and social psychology.Received her M.Ed. from the University of Aberdeen.

The relationship between subjective invulnerability and optimism bias in risk appraisal, and their comparative association
with indices of risk activity, substance use and college adjustment problems was assessed in a sample of 350 (M
age = 20.17; 73% female; 93% White/European American) emerging adults. Subjective invulnerability was measured with the newly
devised adolescent invulnerability scale (AIS). Optimism bias in decision-making was assessed with a standard comparative-conditional
risk appraisal task. Results showed that the danger- and psychological invulnerability subscales of the AIS demonstrated strong
internal consistency and evidence of predictive validity. Subjective invulnerability and optimism bias were also shown to
be empirically distinct constructs with differential ability to predict risk and adjustment. Danger invulnerability and psychological
invulnerability were more pervasively associated with risk behavior than was optimism bias; and psychological invulnerability
counter-indicated depression, self-esteem and interpersonal problems. Results support recent claims regarding the “two faces”
of adolescent invulnerability. Implications for future research are drawn. 相似文献

This article outlines Chinese strategic nuclear forces and the Chinese philosophical approach to nuclear security. It then focuses on the domestic conditions in China which could precipitate vulnerabilities to its nuclear forces. From information about internal security conditions in China, specific internal threats to Chinese nuclear security will be derived. Based on these threats, several outsider and insider scenarios will be outlined involving a variety of terrorist or terrorist related behaviors. These notional scenarios will include everything from overrun or attack, to diversion, to cyber terrorism, to sabotage. The article will then cover what these scenarios and the possible Chinese reaction to them may mean for the security, military and diplomatic strategies of the United States. 相似文献

This article examines the reassessment of U.S. strategy that Dwight D. Eisenhower directed after replacing Harry S. Truman in the White House in January 1953, as he worked to bring the Korean War to an end and then confronted the problems remaining in its aftermath. Despite much of the rhetoric of the early Eisenhower administration, the outcome of that reassessment fit more closely the objective of containment than key strategic formulations of its predecessor. Why was this so? How did the orientation apply to ending the war in Korea and sustaining the U.S. position there and elsewhere after the armistice? What insights, if any, do the process of reassessment and its outcome provide for the present? Answers to these questions serve to emphasize the dynamic and contingent nature of American strategy in the early Cold War and the importance of flexible, engaged leadership in the White House. 相似文献

Following its encounter with insurgent violence in Iraq, the U.S. Department of Defense (DoD) has sought to improve the U.S. military's ability to conduct counterinsurgency. This effort suggests a potential turning-point in the history of the U.S. military, which has traditionally devoted its attention and resources to “high-intensity” or “conventional” combat. Given this institutional culture, what are now the prospects of the U.S. military ‘learning counterinsurgency’? In many ways, the ongoing reorientation is promising and targeted, informed directly by the U.S. campaign in Iraq. At the same time, Pentagon priorities still reveal a remarkable resistance to change, and this in spite of the radically altered strategic environment of the War on Terror. Given this intransigence - and the eventual fall-out from the troubled Iraq campaign - the ongoing learning of counterinsurgency might very well fail to produce the type of deep-rooted change needed to truly transform the U.S. military. 相似文献

This article aims to delineate several issues raised by an historically based approach to understanding the present and the future. Beginning with a discussion of the profound impact that drastic changes have had on the international environment, the article then outlines what history suggests about human nature's influence on the course of future events; the future of war; the nature of governance and the United States. This essay does not attempt to provide answers, but rather suggests how policy makers, strategists, and military leaders might think through the complex political and cultural questions they need to be asking in the making of strategy. This is the essential first step for Americans. If they fail to ask the right questions, most answers will prove irrelevant to the challenges of the future. 相似文献
