This paper reports on an effort to develop an Internet well-being measure for possible use by government agencies and industry associations that are directly involved with the promulgation of the Internet. Such measures can help officials gauge the social health of those Internet-related industries and institutional sectors, which in turn can guide the development of policies to enhance the quality-of-life impact of the Internet. The Internet well-being measure is based on the theoretical notion that the perception of the overall impact of the Internet on users of the Internet is determined by their perceptions of the impact of the Internet in their life domains such as consumer life, work life, leisure life, social life, community life, sensual life, among others. In turn, the perception of impact of the Internet in a given life domain (e.g., consumer life, work life) is determined by perceptions of benefits and costs of the Internet within that domain. We conducted a focus group to identify all the perceived benefits and costs within salient life domains of college students. We also conducted a thorough literature search to identify studies that examined the quality-of-life impact of the Internet in a variety of life domains. We then tested the nomological validity of the measure through two surveys at two major universities (one in the USA and the other in Korea). The statistical analysis allowed us to identify those measurement items that are most predictive, and therefore considered as nomologically valid. Policy implications of the study are discussed along with future research avenues.  相似文献

Brazilian fertility has fallen rapidly in the last three decades, even in the Northeast, the country's poorest region. Female sterilization has become the most common contraceptive method in this region, where 44 percent of married women aged 15–49 years were sterilized as of 1996. While in other regions sterilizations were generally paid for by the patient, politicians and physicians arranged and paid for the large majority of these surgical procedures in the Northeast. The authors present evidence that this phenomenon is the result of the use of sterilization as an electoral good by politicians and physicians in local contexts where politicians regularly provide goods and services to the poor in exchange for votes. This systemic behavior seems to have been little affected by 1997 legislation that regulated family planning, made sterilization legal, and was intended to increase the use of other methods of contraception.  相似文献

A donation paradox occurs when a player gives an apparently valuable prerogative to another player, but does better, according to some criterion. Peremptory challenges, used in choosing a American jury, permit each side to veto a certain number of potential jurors. With even a very simple model of jury selection, it is shown that for one side to give a peremptory challenge to the other side may lead to a more favorable jury, an instance of the donation paradox. Both a theorem and examples are given concerning the existence of the donation paradox in the optimal use of peremptory challenges.  相似文献

The aims of this paper are twofold: first, to set the ratio scaling of opinion in perspective by reviewing a series of laboratory and field experiments designed to build and validate ratio scales of political opinion; and second, to report in detail on the development of calibration procedures designed to obtain proportional judgments from respondents in a national survey.Paralleling explicitly a psychophysical paradigm established for the scaling of physical continua, these studies demonstrate that (1) the paradigm can be adapted to the scaling of sociopolitical opinions; (2) two measures suitable for use in surveys-magnitude estimation and line production-satisfy established psychophysical criteria for valid measures of response; (3) survey respondents can and do make reliable ratio estimates of strength of opinion; (4) scales measuring strength of political support, which are derived from the magnitude and line estimates of survey respondents, match closely the support scales derived in laboratory and field tests using such physical response modalities as handgrip and sound pressure; and (5) these calibration procedures can be incorporated in national opinion surveys.These results, especially the successful move from the laboratory to a conventional survey setting, provide social and behavioral scientists with a technique for generating response data that meet stringent measurement requirements. The calibration procedures described constitute a social metric that will enable researchers to test functional hypotheses in a more rigorous manner than is possible employing alternative scaling procedures.  相似文献

Horrific acts of terrorism have emerged as defining features of Islamic–Western relations throughout much of this still young century. Arising from decades, indeed centuries, of mutual distrust contemporary patterns of radicalized Islamic terrorism toward the West are rooted in their shared histories, traditions, values, norms and, for some, deeply held religious convictions. They also are the product of centuries-long colonization of large regions of the “Islamic world” by Western powers or their proxies. This paper presents an innovative approach for advancing the quality of life of Islamic and Western societies through a fuller understanding of the origins and dynamics of Islamic-inspired terrorist acts against the West. The paper examines the relationship that exists between acts of terrorism associated with a select group of 27 member states of the Organization for Islamic Cooperation (OIC) and: (1) their years of independence since colonization; (2) their current types of polity; (3) the extent of their civil liberties and political freedoms; (4) country levels of perceived public corruption; and (5) the overall level of each country’s broad-based social development (or quality of life). The paper concludes with an “evolving agenda for action” that seeks to advance the quality of life of all people living in Islamic and Western nations.  相似文献

The role of risk preferences in determining the outcome to bargaining is examined for the case in which acceptance of a proposal requires less than unanimous approval. Using an n-agent extension of the Ståhl-Rubinstein alternating offer model, we find that risk preferences play a fundamentally different role when bargaining is settled using a nonunanimity voting rule. Risk preferences determine not only an agent's reservation price but also the likelihood that he is made part of the winning coalition. An implication of this analysis is that when the preferences of the agents are not too diverse, it is advantageous for an agent to be relatively risk-averse.The helpful comments and suggestions of Rich McLean and an anonymous referee are gratefully acknowledged. This article was presented as a paper at the 1988 Winter Econometric Society Meetings.  相似文献

In many naturally occurring situations, actors (agents) use individual sanctions or collective sanctions or both to obtain compliance from members of a group. Individual sanctions are sanctions applied to each individual based on that individual’s perceived behavior; collective sanctions are sanctions to all group members based on perceived behavior by some group members. Often, there are constraints on the amount of sanctions an agent may use. I use Heckathorn’s (1990) sequential decision model of group-mediated social control to analyze the power of an agent concerning compliance by group members under such constraints. Results show that whether positive or negative sanctions are considered, the amount of group compliance is an increasing but non-linear step function of the looseness of the constraints. Moreover, it appears that the most cost-effective use of power entails using only collective sanctions when lower levels of compliance are sought, only individual sanctions when higher levels of compliance are sought, and never mixing the two.  相似文献

This exploratory study examines the associated effects of combat exposure on Soldiers assigned to a Midwestern Army National Guard unit. It also explores the secondary and mediating effects of combat exposure on Soldier’s spouses and children. The correlations of combat exposure with trauma symptoms, substance abuse, domestic violence and secondary trauma symptoms among family members are identified. Survey results suggest that immediate family members of combat-exposed Soldiers with high levels of post traumatic stress disorder (PTSD) are at risk for developing secondary traumatic stress. Secondary trauma symptoms in these spouses are a risk-increasing mediating variable between trauma symptoms in combat-exposed Soldiers and secondary trauma symptoms in their children. Results from this investigation emphasize the need for further inquiry into this topic. They further highlight the need for preventive and treatment efforts targeted toward all family members and relationships in order to lessen the effects of combat exposure.  相似文献

The policies determining how the foreign born enter the United States are some of the most complicated, least understood, and most disliked of all federal policies. This paper uses New Immigrant Survey (2003) data to examine how proposed changes to U.S. immigration policy might alter the composition of legal permanent residents (LPRs) admitted. Specifically, we consider the 2007 federal proposal that would have placed greater emphasis on employment and skills by instituting a merit-based point system while eliminating some types of family sponsorship. We also simulate point scores for the 2003 LPR cohort according to the point systems used in Canada and Australia. We find that, despite significant variation in point allocations, the three systems would admit similar numbers and types of immigrants. In the 2007 U.S. proposal, work experience in the United States is extremely important for earning high point scores. Thus, the proposal would place even more stress on temporary visa programs.  相似文献
