There are numerous situations where governments take action due to systematic information asymmetries in society, while economics textbooks do not offer an integrated theory to justify these interventions in terms of utility. This paper starts with a taxonomy of situations where governments try to correct for information asymmetries. A distinction is made between government interventions due to information asymmetries between market partners, within political markets and between the government and citizens. It is then shown that Public Choice Theory offers only few and Public Finance Theory not enough explanations for the prevalence of such government interventions. Further explanations for government actions are given by Institutional Economics and Cultural and Behavioural Economics. The latter will probably generate the best progress towards creating better explanations. 相似文献

Growing interest in the environmental aspects of migration is not matched by research on their interrelationships, due partly to the lack of adequate data sets on the two together. Focusing on the microlevel, we describe the data required to effectively investigate these interrelationships. Data sources are discussed, including information that should be collected, focusing on household surveys and remote sensing. The main section of the paper describes three alternative approaches to data collection: (a) using existing population and environmental data from different sources, illustrated by Burkina Faso; (b) adding questions to a survey developed for another purpose, illustrated for Guatemala using a DHS survey; and (c) designing a new survey specifically to collect both migration and environmental data to investigate interrelationships, illustrated by Ecuador. Methods used and summary findings are described, followed by a discussion of their advantages and limitations. We conclude with recommendations as to effective use of each approach as research on migration?Cenvironment linkages moves forward. 相似文献

In this paper I first review the basic tenets of agency theory and theory of managerial capitalism as well as some of the
major research in these areas then suggest for areas for future research that go beyond the extant empirical work. First,
I suggest that it would be useful to reconsider the basic nature of the agency relationship, taking into account that while
equity holders can be considered the principal, the board of directors may be more realistically in need of agent-like controls.
Second, the complementary or supplementary nature of the monitoring/incentive alignment relationship has been shown theoretically
but the empirical evidence is equivocal and needs future investigation. Third, there has been very limited research on the
construct validity of archival measures of the sort used in agency theory. This requires the use of methodologies outside
those of the more conventional type used in agency theory (i.e., from economics and finance). Finally, agency theory development
would profit greatly by more extensive use of research methods such as laboratory studies and survey methodology and the integration
of concepts such as personality and control processes.

Most commentary on the Edward Snowden affair and other recent accounts of government spying leaked in the media has focused on individual privacy concerns, while overlooking how contemporary neoliberal modernity has created a social order in which new surveillance technologies grant the state a degree of power unthinkable to past generations – exceeding in reach and complexity even the totalitarian state imagined in Orwell's dystopian account, 1984. Any critical analysis of the modern surveillance state must move beyond documenting abuses of state power to address how government repression has been allowed to proceed unchecked, and even to flourish, through its support of an antidemocratic public pedagogy produced and circulated via a depoliticizing machinery of fear and consumption. In the USA, repression works through the homogenizing forces of the market as well as a corresponding loss of public memory and political identity to encourage the widespread embrace of an authoritarian surveillance culture. The state and corporate cultural apparatuses now collude to socialize everyone into a surveillance regime, even as personal information is willingly given over to social media and other corporate-based sites as people move across multiple screens and digital apparatuses. It is no longer possible to address the violations committed by the surveillance state without also analysing this broader regime of security and commodification. The authoritarian nature of the corporate–state surveillance apparatus in the USA can only be fully understood when its ubiquitous tentacles are connected to wider cultures of entertainment, commerce and punishment, and the increasing labelling of democratic dissent as an act of terrorism. If democracy is to have a future in America, then it is imperative to organize social movements capable of recovering public memory and reclaiming dissent as essential features of responsible citizenship. 相似文献

Despite the growing body of research examining the experience of stepparents, very little is known about the unique experience of nonresidential stepparents. This research examined the experience of nonresidential stepmothers (N = 10) using semistructured interviews. Thematic content analysis identified 2 principal themes. Those themes were perceived control (with the subtheme of visitation and parenting and financial matters) and psychological and physical well-being. The perceived inability to control parenting practices during periods of visitation and financial matters associated with the payment of child support generated a sense of powerlessness, anger, and resentment that manifested in depression. Implications for family service providers and clinicians working with stepfamilies are discussed. 相似文献

Thematic analysis is frequently used to analyse qualitative data in psychology, healthcare, social research and beyond. An important stage in planning a study is determining how large a sample size may be required, however current guidelines for thematic analysis are varied, ranging from around 2 to over 400 and it is unclear how to choose a value from the space in between. Some guidance can also not be applied prospectively. This paper introduces a tool to help users think about what would be a useful sample size for their particular context when investigating patterns across participants. The calculation depends on (a) the expected population theme prevalence of the least prevalent theme, derived either from prior knowledge or based on the prevalence of the rarest themes considered worth uncovering, e.g. 1 in 10, 1 in 100; (b) the number of desired instances of the theme; and (c) the power of the study. An adequately powered study will have a high likelihood of finding sufficient themes of the desired prevalence. This calculation can then be used alongside other considerations. We illustrate how to use the method to calculate sample size before starting a study and achieved power given a sample size, providing tables of answers and code for use in the free software, R. Sample sizes are comparable to those found in the literature, for example to have 80% power to detect two instances of a theme with 10% prevalence, 29 participants are required. Increasing power, increasing the number of instances or decreasing prevalence increases the sample size needed. We do not propose this as a ritualistic requirement for study design, but rather as a pragmatic supporting tool to help plan studies using thematic analysis. 相似文献

A group of 209 married, fecund women in rural Bangladesh were studied prospectively for 24 months from 1969 to 1971 to define some of the biological and sociological factors relating to fertility performance. These women were selected from a larger study population of 112,000 that had been followed with a daily house-to-house vital registration programme since 1966. The selected women were interviewed bi-weekly and were asked questions about menstruation, pregnancy, lactation, husband's occupational absences, and monthly urine tests for pregnancy were taken. The results for 193 non-contracepting women revealed that the seasonal pattern of births previously observed in this population could be associated with a corresponding seasonal pattern of conceptions and that this was due to a seasonal trend in fecundability. The highest conception rates were in the coolest months of the year. Post-partum lactational amenorrhoea was very prolonged, averaging 17 months for women with a surviving child. The appearance of the first post-partum menstrual flow (onset of ovulation) also had a seasonal trend which could not be adequately explained. The median waiting time to conception, once menstruation had resumed was eight months. This interval was influenced by seasonal fluctuations, as well as by the age of women and by husbands' absences. The foetal wastage rate was 15·0 per 100 conceptions, with 62 per cent of the foetal losses occurring during the second month of gestation. Overall, the average birth interval was 33 months, with the prolonged lactational amenorrhoea accounting for almost 45 per cent of this interval. 相似文献

ABSTRACT Homophobia and heterosexism often can negatively affect a gay male's development, and developing internalized homophobia can challenge connecting with others. Using a sample of eight therapist–patient pairs (16 participants), each participant responded to how often the therapist self-disclosed. In addition, each participant completed a measurement inventory to determine how connected each was to the other (patient to therapist or therapist to patient). Findings indicated that self-disclosure occurred often during therapy, and there was a fairly high level of connection between patients and therapists. Patients who perceived that their therapists self-disclosed more often also reported higher levels of connection when compared with those who perceived a lower level of therapist self-disclosure. Recommendations for future research are made along with practice implications designed to help therapists effectively use self-disclosure when working with gay male clients. 相似文献

This article reports the findings from a questionnaire survey of university students’ life satisfaction in Regina. The results demonstrated that a significant proportion of the 315 respondents were satisfied with their lives (N = 240, 76.2%). With regard to degree of satisfaction with different aspects of life, respondents expressed that they were most satisfied with relationship with mother, living environment, relationships with close friends, relationships with siblings, and living arrangement. Multiple ordinary least-squares regression analyses revealed that respondents who indicated a higher socio-economic status, achieveda higher grade point average, and were more satisfied with their academic experience, self-esteem, relationship with significant other, and living conditions, expressed a markedly higher level of satisfaction with life. 相似文献
