In the past three different paradigms or, more loosely, frames of reference, have been used by students of politics to interpret various dimensions of mass political participation. Each of these, which are referred to as the political socialization, the group interests and beliefs, and the political party/organization paradigms, has received empirical support for its scheme of interpretation; yet recent political events also suggest that these frames of reference may be inadequate, and may need to be complemented, if not replaced, by other schemes. The present paper outlines one such scheme, drawing upon recent writings on social networks and social influences on political participation. It relies on the metaphor of a political arena, and proposes two simple propositions to account both for conventional and unconventional participation in this arena.An earlier version of this paper was delivered at the Annual Meetings of the Society for the Study of Social Problems, New York, NY, August 1976.  相似文献

In the years following World War One the pastoral populations of northern Arabia were subjected to political pressures and economic hardships arising from the creation of French and British spheres of influence in the territories that would become the states of Jordan, Syria and Iraq, and by the aggressive expansion of the domains of the ruler of Najd, ‘Abd al-‘Aziz ibn ‘Abd al-Rahman Al Saud. Year by year the nascent states in the region asserted more control over the vast stretches of desert and steppe that had heretofore been the domains of powerful bedouin tribes and confederations. New borders often cut across tribal territories creating complications and conflict in such matters as sovereignty, citizenship, migration, raiding and political refuge. The establishment of new customs regimes and economic policies meant that age-old patterns of trade between the settled and nomadic populations were altered, curtailed or criminalized as ‘smuggling’.

This article examines two sets of policies that Iraqi and Saudi forces employed to express political domination in the desert and steppes of Kuwait and beyond in the guise of controlling trade: the Saudi blockade of overland trade with Kuwait; and Iraq's aggressive ‘anti-smuggling’ measures that often victimized innocent bedouin. In both cases, members of bedouin tribes were harassed, attacked, pillaged and forced to alter their normal patterns of trade and migration. The eventual rise and dominance of state power resulted in the historic defeat of bedouin control in the deserts and steppes and a gradual loss of their traditional economic options. This article provides detailed evidence showing how part of this large transformation in bedouin society took place.  相似文献

A 1H nuclear magnetic resonance (1H NMR) method for the determination of gamma-hydroxybutyric acid (GHB) and gamma-hydroxybutyrolactone (GBL) in human serum and urine using spiked samples has been developed. The method gives linear responses (correlation coefficients of 0.99 or greater) over the concentration range 0.01 mg/mL to 4.0 mg/mL in urine and 0.3 mg/mL to 2.0 mg/mL in serum. No sample pretreatment is required. Studies of the chemical interconversion of GBL and GHB showed hydrolysis of GBL to be rapid at pH 11.54, slower and less complete (30% hydrolysis) at pH 2.54 and slowest at pH 7.0, reaching 30% hydrolysis in about 40 days. No esterification of GHB was observed at any pH.  相似文献

Jurors in negligence cases are supposed to judge a defendant by the reasonableness of his or her conduct and not by the consequences of that conduct. But several studies have shown that a cognitive heuristic known as hindsight bias can skew post hoc judgments of some prior behavior. Thus, jurors who must evaluate the actions of a defendant may be influenced inappropriately by the consequences of those actions. A complementary problem arises when jurors must evaluate the injuries incurred by the plaintiff. Here, jurors' knowledge about the defendant's allegedly negligent conduct can proactively influence their assessment of the plaintiff's injuries and determination of damages. The purpose of the present study was to examine the effectiveness of two procedural techniques intended to reduce or eliminate the impact of hindsight bias in negligence cases—multiple admonitions from a judge about the proper use of evidence—and bifurcation (actually withholding irrelevant evidence from jurors). We presented a re-enacted automobile negligence trial to 355 jury-eligible adults drawn from the community, varied the evidence and instructions that they heard, and measured liability judgments and damage awards from individual jurors both before and after deliberating, and from juries. Results showed that admonitions were generally ineffective in guiding jurors to the proper use of evidence but that bifurcation was relatively more effective. Deliberations had no curative effect on jurors' misapplication of evidence.  相似文献

The influence of crime among the elderly was investigated in this study. The study suggests that crime prevention programs among the elderly should be implemented with some reservations. Since the risks of criminal victimization are low among the elderly, it may not be possible to reduce those rates much further, even with elaborate security programs for the elderly. On the contrary, raising the salience of crime by placing great emphasis on preventive behavior may well foster social isolation among the elderly.  相似文献
