As the development and use of automated systems for collaborative work grows, the need for a better understanding of these systems becomes more important. Our focus is on one type of system, a Group Support System (GSS) and, in particular, on one important aspect of a GSS—anonymity. A conceptual framework for the study of anonymity in a GSS is presented, which describes the general classes of variables and their relationships. These variables include the factors that influence anonymity in a GSS, types of anonymity, and the effects of anonymity on a message sender, receiver, group process, and outcome. Each of these variables is discussed with working propositions presented for important group process and outcome measures. The objectives of this article are to highlight the importance and complexity of anonymity, to act as a guide for empirical investigations of anonymity, and to influence future GSS development and use.  相似文献

Abstract

This study explores the mediating role political visualization – the process of imagining future political scenarios – plays in determining how political advertising affects voting behaviour. Specifically, we theorize that when partisans are exposed to political ads that are narrative (compared to non-narrative) in nature, they will engage in more political visualization. Partisans will then experience emotional reactions to these imagined futures – specifically, enthusiasm for the in-group candidate and anger towards the out-group candidate. These emotional reactions, in turn, will make a partisan more likely to vote for the in-group candidate and less likely to vote for the out-group candidate. We test this model by employing an experimental design where American partisans were presented a political ad (in the form of an email) that is either narrative or non-narrative. Results provide support for most of our expectations and suggest that visualization may play an important role in determining the influence of a political ad.  相似文献

In this study, we assessed the epidemiological patterns of suicide terrorism in the civilian population of Pakistan. Information about suicide terrorism-related events, deaths and injuries was extracted from the South-Asian Terrorism Portal (SATP) for the period from 2002 to October 2009. Of 198 events, civilians were involved in 194 events. Civilians accounted for 74.1% (N?=?2017) of those who died and 93.8% (N?=?6129) of those who were injured. In nine districts, mortality rates were more than one death per 100,000 inhabitants per year. The yearly trend showed a shift of attack targets from foreigners and sectarian targets in 2002-2005 to security forces or general public in 2006-2009. Attacks on public installations (mosques) or political gatherings resulted in a significantly greater (P?≤?0.02) number of deaths (22 vs. 8) and injuries (59 vs. 24) per event compared with security installations. These results show that prevention might focus on political negotiation with armed groups and that appropriate measures should be taken to protect mosques and political gatherings.  相似文献

Aims: To better understand the impact of the clinical course of multiple sclerosis (MS) and disability on employment, absenteeism, and related factors.

Materials and methods: This study included respondents to the North American Research Committee on Multiple Sclerosis Registry spring 2015 update survey who were US or Canadian residents, aged 18–65 years and reported having relapsing-remitting MS (RRMS), secondary progressive MS (SPMS), or primary progressive MS (PPMS). The RRMS and SPMS participants were combined to form the relapsing-onset MS (RMS) group and compared with the PPMS group regarding employment status, absenteeism, and disability. Multivariable logistic regression was used to examine the relationship between employment-related outcomes and factors that may affect these relationships.

Results: Of the 8004 survey respondents, 5887 (73.6%) were 18–65 years of age. The PPMS group (n?=?344) had a higher proportion of males and older mean age at the time of the survey and at time of diagnosis than the RMS group (n?=?4829). Female sex, age, age at diagnosis, cognitive and hand function impairment, fatigue, higher disability levels, ≥3 comorbidities, and a diagnosis of PPMS were associated with not working. After adjustment for disability, the employed PPMS sub-group reported similar levels of absenteeism to the employed RMS sub-group.

Limitations: Limitations of the study include self-report of information and the possibility that participants may not fully represent the working-age MS population.

Conclusions: In MS, employment status and absenteeism are negatively affected by disability, cognitive impairment, and fatigue. These findings underscore the need for therapies that prevent disability progression and other symptoms that negatively affect productivity in persons with MS to enable them to persist in the workforce.  相似文献

Lack of clarity behind measurement and interpretation of statistics on gender and land leads to an inability to clearly articulate a policy response to the potential inequalities faced by women and men. This article sets out to explore, conceptually and empirically, the levels and relative inequalities in land rights between women and men in African countries. The first section of the article engages in a conceptual discussion of how to measure gendered‐land outcomes, what ownership and control mean in different contexts, and why attention to these factors is important for the development of gender and land statistics. The second section of the article systematically reviews existing evidence from microlevel large sample studies to summarize recent trends in land access, ownership, and control by sex. The third section presents new statistics from a variety of nationally representative and large‐scale unpublished data on gender and land in Africa. Results provide not only a nuanced understanding of the importance of measuring land indicators for gendered development in Africa and globally but also new statistics on a variety of land outcomes to aid stakeholders in the discussion of gender‐land inequalities.  相似文献

So Then Why Did You Do It?   总被引:1,自引:0,他引:1  
What causes unethical behavior and what can we learn from those individuals who have had spectacular ethical lapses? The profiles of six prominent individuals, including Dennis Levine, Charles Keating, and Robert Citron are examined to try to provide some insight into what lead them down the slippery slope to criminal and unethical behavior. What we found is that all six certainly knew that they were breaking the law and most went to extra-ordinary lengths to cover up what they were doing. Additionally, we found that each individual had attained a position of authority that enabled them to break the law without being seriously challenged by others who knew, or suspected, what was being done. Each person was highly compensated for their efforts, yet, they choose to engage in unethical and illegal activities in the pursuit of just a little more money or power.  相似文献

We examine the impact of institutional trading on stock resiliency during the financial crisis of 2007–2009. We show that buy-side institutions have different exposure to liquidity factors based on their trading style. Liquidity supplying institutions absorb the long-term order imbalances in the market and are critical to recovery patterns after a liquidity shock. We show that these liquidity suppliers withdraw from risky securities during the crisis and their participation does not recover for an extended period of time. The illiquidity of specific stocks is significantly affected by institutional trading patterns; participation by liquidity supplying institutions can ameliorate illiquidity, while participation by liquidity demanding institutions can exacerbate illiquidity. Our results provide guidance on why some stocks take longer to recover in a crisis.  相似文献

This paper investigates the role of the individual specialist vis-à-vis that of the specialist firm on the quality of markets. While previous studies have not denied the importance of the individual, they have focused exclusively on the performance of the specialist firm. This study is the first empirical test of the specialist as an individual and his influence on market quality. By implication, it tests whether the firm is the appropriate level of analysis. Within specialist firms, we find significant differences in quoting behavior while the evidence on execution quality is mixed. Some firms are able to design an effective mechanism that enforces uniformity in goals of the members of the firm. Considering that exchanges are unable to impose such uniform performance, these firms appear to have better incentive or penalty systems in place. However, the existence of other firms where significant differences in execution quality exist, presents a challenge to policy makers, as differences in execution quality within a firm indicate that the disclosure of market quality needs to be at the post-level, not just at the firm level.  相似文献

Economics of Food Labeling   总被引:3,自引:0,他引:3  
Federal intervention in food labeling is often proposed with the aim of achieving a social goal such as improving human health and safety, mitigating environmental hazards, averting international trade disputes, or supporting domestic agricultural and food manufacturing industries. Economic theory suggests, however, that mandatory food-labeling requirements are best suited to alleviating problems of asymmetric information and are rarely effective in redressing environmental or other spillovers associated with food production and consumption. Theory also suggests that the appropriate role for government in labeling depends on the type of information involved and the level and distribution of the costs and benefits of providing that information. This report traces the economic theory behind food labeling and presents three case studies in which the government has intervened in labeling and two examples in which government intervention has been proposed.  相似文献

The commercialization of technological innovation, which is key to entrepreneurial success, represents a combination of several entrepreneurial activities. Building on research in management, strategy, entrepreneurship, and economics, this research summarizes 194 articles from 62 journals, categorizing them into six broad entrepreneurial activity themes: sources of innovations, types of innovation, market entry competence and feasibility, protection, development, and deployment. This review and synthesis suggest a framework of commercialization and an agenda for future research along with recommendations and guidance for future research. The proposed agenda provides topics and research questions for research, as well as related recommendations regarding the study and practice of the commercialization of innovation.  相似文献
