To extend research linking pubertal timing and adolescent health outcomes, this study examines boys’ pubertal timing and subsequent interpersonal success and health behaviors in mid adulthood. Past research has shown that boys’ pubertal timing is associated with both positive and negative developmental outcomes in the short term, and so it is unclear how pubertal timing is consequential for adjustment across the long term. Data from 460 boys from the Terman Life-Cycle Study were examined over a 39-year period to relate age of pubertal onset to later marital success, career success, and adult health behaviors. Boys who reached puberty earlier than their peers achieved greater success in their careers and experienced more satisfaction in their marriages. Early-developing boys were not found to be more likely than their peers to smoke cigarettes or drink alcohol as adults. Findings are discussed in terms of the importance of pubertal timing for life-span development.Keiko Taga is a doctoral student at the Department of Psychology at University of California, Riverside.

Taiwan is a revisionist power. Its independence movement challenges a vital status-quo interest of mainland China's opposition to a de jure Taiwan declaration of independence and maintaining, however ambiguously, Taiwan's commitment to the ‘one-China’ formulation. Why is it that a small and vulnerable island off the coast of a great power has continued to challenge the vital interest of that great power and risk war? Adopting a ‘levels of analysis’ approach to Taiwan's mainland policy, this paper addresses this question by examining four prevalent explanations for Taiwan's revisionist diplomacy: (1) the mainland deterrent is ineffective, reflecting Taiwan doubts about either mainland capabilities or mainland resolve to wage a retaliatory war; (2) in an example of the security dilemma in alliance politics, US commitment to Taiwan, although aimed at deterring PRC use of force, encourages Taiwan to challenge the status quo because the Taiwan leadership is confident of US intervention and US ability to defend Taiwan; (3) because of the development of a ‘Taiwan identity’ and of corresponding domestic political pressures, the Democratic Progressive Party has been compelled to adopt a pro-independence policy; (4) Chen Shui-bian has a personal commitment to Taiwan independence and has been willing to challenge the mainland's interest in one-China, despite risk of heightened conflict and regardless of domestic political considerations.  相似文献

The literature on the implications of electoral "bureaucracy bashing" for public management is thin. This is partly because of the difficulty of defining basic terms and measuring results in meaningful ways. Using focus group data, this article explores how senior federal managers perceive campaign bureaucracy bashing and assess its consequences. The participants perceive that candidate-based bashing affects federal management on two levels: one emotional, the other programmatic. The emotional impact is pronounced, producing frustration and hostility from senior managers toward political candidates, political appointees, and the media. Senior managers report that bashing adversely affects policy implementation through low morale, poor recruitment, and training and by fostering an environment of distrust toward bureaucracy. Grounded in a diverse literature relating to public administration, the presidency, campaigns and elections, and political communication, this inquiry finds that senior managers confirm many of the speculations these works raise about how bashing affects public employees and public policy.  相似文献

This article analyzes performance and organizational issues revealed by the governmental response to Hurricane Katrina. It reviews and analyzes the organizational changes made in the federal government to address homeland security and presents several proposals for reorganization suggested by policy makers in the aftermath of Katrina. A management approach rooted in adaptive management is presented for use in the ongoing process of organizing for homeland security.  相似文献

Hurricane Katrina revealed a lack of preparedness in disaster management networks covering the New Orleans area. This paper focuses on the operation of networks in preparing to evacuate residents in advance of a major disaster. There are two cases: the relatively successful evacuation of residents who left by private conveyance and the widely publicized failure to provide for those who could not or would not leave on their own. We trace the actions and inactions of various players to reach conclusions about the strengths and weaknesses of networks in the special circumstances of disaster preparation.  相似文献

A Unified Theory and Test of Extended Immediate Deterrence   总被引:1,自引:0,他引:1  
We present a unified theory and test of extended immediate deterrence—unified in the sense that we employ our theoretical deterrence model as our statistical model in the empirical analysis. The theoretical model is a straightforward formalization of the deterrence logic in Huth (1988) and Huth and Russett (1984) , coupled with private information concerning utilities. Our statistical analysis suggests that the attacker and defender's decisions are influenced by the balance of forces, nuclear weapons, defender-protege military alliances, arms transfers, and trade, as well as the regime types of those involved. Many of these findings contradict previous research by Huth (1988) and Huth and Russett (1988) . We find that many of the variables involved in the deterrence calculus are nonmonotonically linked to the probability of deterrence success or war. We illustrate the results with case studies of the Soviet-Japanese dispute over Manchukuo (1937–1938) and the Berlin Blockade (1948).  相似文献

This article examines the prevalence and consequences of authoritarian attitudes among elites in Argentina, Brazil, Chile, Colombia, Mexico, and Venezuela. We focus on the connection between antidemocratic elite attitudes and support for democracy; the causes and effects of authoritarian attitudes among elites and their implications for authoritarianism; and the impact of authoritarian attitudes beyond social policy preferences to other policy areas that have indirect implications for order. Contrary to some of the literature, we find that antidemocratic attitudes affect elites' support for democracy. Our analysis also speaks to the debate on the origins of authoritarianism. Much of the evidence supports Altemeyer's notion that perceived threat raises levels of authoritarianism, rather than Feldman's contention that threat strengthens the influence of authoritarian attitudes. Finally, we demonstrate that there is a broader influence of authoritarian attitudes on economic policy preferences, but only where those policies appear to have implications for social order.  相似文献

Abstract.  This article examines the capacities of various regimes to master conflicts. The capacities of regimes are measured by an empowerment index that reflects more accurately the capacity of states to manage conflicts than measures of democracy. The study draws from a wide range of indicators to calculate values of the independent variables 'challenges' and 'support' for each existing state. In addition to these explanatory factors, regime factors are calculated independently. The dependent variable 'conflict' draws on the data set by Kosimo ( http://www.kosimo.de ) and is based on the number of conflicts occurring between 1945 and 2000. These conflicts are then considered in relation to the management capacities of each state. The analysis shows that the empowerment indicator is a better predictor of conflict involvement than the regime indicator. Cross-calculations also show that, not surprisingly, on the whole, democracies have had a better record in the management of conflicts than other regimes.  相似文献

The compromise enhancing effect of lobbying on public policy has been established in two typical settings. In the first, lobbies are assumed to act as “principals” and the setters of the policy (the candidates in a Downsian electoral competition or the elected policy maker in a citizen-candidate model of electoral competition) are conceived as “agents”. In the second setting, the proposed policies are solely determined by the lobbies who are assumed to take the dual role of “principals” in one stage of the public-policy game and ‘agents’ in its second stage. The objective of this paper is to demonstrate that in the latter setting, the compromising effect of lobbying need not exist. Our reduced-form, two-stage public-policy contest, where two interest groups compete on the approval or rejection of the policy set by a politician, is sufficient to show that the proposed and possibly implemented policy can be more extreme and less efficient than the preferred policies of the interest groups. In such situations then more than the calf (interest groups) wish to suck the cow (politician) desires to suckle thereby threatening the public well being more than the lobbying interest groups. The main result specifies the conditions that give rise to such a situation under both the perfectly and imperfectly discriminating contests.  相似文献
