Good social and political theory is parsimonious, cumulative, counter‐intuitive, and relevant to well‐intended efforts to solve gripping social problems. This introduction to the Festschrift shows that in developing ‘rubbish theory’ and ‘cultural theory’ the work of Michael Thompson meets all these criteria. Added is a ‘top 10’ of quotes from Thompson's work, an overview of his academic career, as well as a bibliography. 相似文献

More than 80% of Italian men aged 18–30 live with their parents. We argue that one contributing factor to this remarkably high rate of cohabitation is parents' tastes for coresidence. In order to investigate the role of parental preferences, we estimate the effect of exogenous changes in parental income on rates of cohabitation in Italy using Survey of Households' Income and Wealth (SHIW) micro data from 1989 to 2000. In order to identify a source of exogenous variation in parental income, we use changes in fathers' retirement age induced by the 1992 reform of the Italian Social Security system as an instrumental variable for parental income. By raising retirement age, this reform forced some fathers to remain in the labor market longer than they would have otherwise, therefore raising their disposable income. We use a two‐sample instrumental variable (TSIV) strategy. Our TSIV estimates indicate that a rise in parents' income significantly raises the children's propensity to live at home: A 10% increase in annual parental income results in approximately a 10% rise in the proportion of men living with their parents. Although we cannot definitely rule out alternative interpretations, these results are consistent with our hypothesis that cohabitation is a normal good for Italian parents.

This study examined whether home‐based family therapists' (HBFT) workload and clinical experience were associated with therapists' professional quality of life directly and indirectly through self‐care activities and frequency of clinical supervision. Hypotheses were tested using structural equation modeling with a sample of 225 home‐based therapists. Results suggested that therapists' workload and HBFT experience significantly predicted therapists' professional quality of life. These associations between therapists' workload and HBFT experience were partially mediated through participation in self‐care and frequency of clinical supervision. Implications for improving therapists' quality of life are discussed as a function of therapists' workload, clinical experience, self‐care, and supervision. 相似文献

In this work, we study the environmental and operational factors that influence airborne transmission of nosocomial infections. We link a deterministic zonal ventilation model for the airborne distribution of infectious material in a hospital ward, with a Markovian multicompartment SIS model for the infection of individuals within this ward, in order to conduct a parametric study on ventilation rates and their effect on the epidemic dynamics. Our stochastic model includes arrival and discharge of patients, as well as the detection of the outbreak by screening events or due to symptoms being shown by infective patients. For each ventilation setting, we measure the infectious potential of a nosocomial outbreak in the hospital ward by means of a summary statistic: the number of infections occurred within the hospital ward until end or declaration of the outbreak. We analytically compute the distribution of this summary statistic, and carry out local and global sensitivity analysis in order to identify the particular characteristics of each ventilation regime with the largest impact on the epidemic spread. Our results show that ward ventilation can have a significant impact on the infection spread, especially under slow detection scenarios or in overoccupied wards, and that decreasing the infection risk for the whole hospital ward might increase the risk in specific areas of the health‐care facility. Moreover, the location of the initial infective individual and the protocol in place for outbreak declaration both form an interplay with ventilation of the ward. 相似文献

ABSTRACTThis introduction to the special issue considers how independent research on mis/disinformation campaigns can be conducted in a corporate environment hostile to academic research. We provide an overview of the disinformation landscape in the wake of the Facebook-Cambridge Analytica data scandal and social platforms’ decision to enforce access lockdowns and the throttling of Application Programming Interfaces (APIs) for data collection. We argue that the governance shift from user communities to social media algorithms, along with social platforms’ intensive emphasis on generating revenue from user data, has eroded the mutual trust of networked publics and opened the way for dis/misinformation campaigns. We discuss the importance of open, public APIs for academic research as well as the unique challenges of collecting social media data to study highly ephemeral mis/disinformation campaigns. The introduction concludes with an assessment of the growing data access gap that not only hinders research of public interest, but that may also preclude researchers from identifying meaningful research questions as activity on social platforms becomes increasingly more inscrutable and unobservable. 相似文献

This article investigates the links between earnings, human capital and job tasks, using internationally comparable information from the OECD Survey of Adult Skills. The authors use the theoretical framework developed by Autor and Handel (2013) and extend their empirical results to 21 OECD countries. The data allow for a richer characterization of workers' human capital by including both educational attainment and a measure of cognitive skills. Their findings confirm the predictive power of job tasks in explaining wage differences, both between and within occupations, and provide empirical support for the model's prediction in the vast majority of countries. 相似文献

Norms of cooperation and punishment differ across societies, but also within a single society. In an experiment with two subject pools sharing the same geographical and cultural origins, we show that opportunities for peer punishment increase cooperation among students but not in the general population. In previous studies, punishment magnified the differences across societies in people's ability to cooperate. Here, punishment reversed the order: with punishment, students cooperate more than the general population while they cooperate less without it. (JEL C72, C90, Z13) 相似文献

This paper presents a political economy theory of fiscal policy and unemployment. The underlying economy is one in which unemployment can arise but can be mitigated by tax cuts and increases in public production. Such policies are fiscally costly, but can be financed by issuing government debt. Policy decisions are made by a legislature consisting of representatives from different political districts. With the available policies, it is possible for the government to completely eliminate unemployment in the long run. However, with political decision making, the economy always has unemployment. Unemployment is higher when the private sector experiences negative shocks. When these shocks occur, the government employs debt‐financed fiscal stimulus plans which involve both tax cuts and public production increases. When the private sector is healthy, the government contracts debt until it reaches a floor level. Unemployment levels are weakly increasing in the economy's debt level, strictly so when the private sector experiences negative shocks. Conditional on the level of workers employed, the mix of public and private output is distorted. 相似文献

In this study, we explore the fluctuations of unemployment and vacancies in the Italian labour market over the last 20 years. Relying on the available sources of data for unfilled job openings, we find that even in Italy, similarly to other developed countries, there is a clean evidence of the unemployment volatility puzzle. In other words, we empirically assess that the tightness indicator is significantly more volatile than productivity over the whole period. In addition, on the theoretical ground, we show that a matching model with segmented labour markets and on‐the‐job search has the potential to provide a rationale for this pattern. 相似文献
