We examine whether nations, faced with the threat of terrorism, will be motivated to engage in the efficient amount of retaliation against terrorists. We demonstrate that the problem confronting the efforts of nations to achieve an optimal retaliation against terrorists is understated by the traditional free-rider analysis. In particular, nations have the option of actually selling or reducing the public good of retaliation, provided through the efforts of others, by offering safe havens to terrorists in return for the terrorists' pledge to attack elsewhere. This paid-rider behavior is also shown to apply to other public good scenarios.The authors gratefully acknowledge the helpful comments of Gordon Tullock on an earlier draft. Sole responsibility for the paper's content rests with the authors.

This study examined the influence of pubertal timing upon family interactions in normal and psychiatric adolescent samples. An important feature of our approach is its emphasis upon micro-analysis of family behaviors (individual speeches) and family processes (theoretically specified speech pairings). Rather than assume that global family patterns (e.g., power) shift in response to pubertal changes, we follow how types of speeches and speech sequences are associated with different pubertal timing. Using the previously constructed family coding system, the Constrainig and Enabling Coding System, we found that on-time adolescents and their parents differed from both off-time groups (early or late). These results are discussed in terms of current implications and suggestions for future research.An earlier version of this paper was presented at the SRCD Study Group on Timing of Maturation, October, 1983, at the Education Testing Service, Princeton, NJ.

This article examines the mode of understanding and experiences of family relationships of Chinese migrant women in Britain. In contrast to much existing research work on the patterns and experiences of postwar settlement of unskilled Chinese male labourers in Britain, the focus here is on the life stories of 41 Chinese women with different migration trajectories and varying economic and cultural capital. Their oral testimonies reveal Chinese women's diverse expectations and experiences of migrant family relationships and their different strategies to achieve self-fulfillment both within and outside the confines of the migrant family. For some women, migration brings opportunities for a fulfilling and independent lifestyle. They are successful in negotiating their way around and sometimes out of their initial familial and social position. For others, they bear the disproportionate cost and labour of familial strategies of advancement and remain vulnerable to the most constraining aspects of diasporic existence.  相似文献

A method for simultaneous enantiomeric separation of ephedrine, pseudoephedrine, and methamphetamine (MA) in a single run by simple capillary zone electrophoresis (CZE) with beta-cyclodextrin as a chiral selector is described. The effects of the buffer pH, phosphate concentration, beta-cyclodextrin concentration, voltage and temperature on the peak resolution were examined. Good enantiomeric resolution was attained for each analyte under our optimized conditions: 15 mM beta-cyclodextrin, 300 mM NaH2PO4 at pH 2.5 with an uncoated capillary (64.5 cm x 50 microm), applied potential at 20 kV and temperature at 30 degrees C. Ultraviolet (UV) detection at a fixed wavelength (200 nm) was employed using a diode array detector. Using phentermine as an internal standard, migration times for all analytes are reproducible within 0.16% for intra-day and 0.6% for inter-day runs. Application of this method to the analysis of confiscated drugs is discussed.  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
