This paper combines novel data on the time use, home-learning practices and economic circumstances of families with children during the COVID-19 lockdown with pre-lockdown data from the UK Time Use Survey to characterise the time use of children and how it changed during lockdown, and to gauge the extent to which changes in time use and learning practices during this period are likely to reinforce the already large gaps in educational attainment between children from poorer and better-off families. We find considerable heterogeneity in children's learning experiences – amount of time spent learning, activities undertaken during this time and availability of resources to support learning. Concerningly, but perhaps unsurprisingly, this heterogeneity is strongly associated with family income and in some instances more so than before lockdown. Furthermore, our analysis suggests that any impacts of inequalities in time spent learning between poorer and richer children are likely to be compounded by inequalities not only in learning resources available at home, but also in those provided by schools. 相似文献

This study examines whether the volatility of interim estimates of the annual effective tax rate (ETR) provides ex ante information about the quality of firms' internal control environments. Recent research suggests that some firms selectively disclose internal control weaknesses (ICWs). Given the negative consequences associated with ICWs, it is important for capital market participants to be able to identify firms with ineffective internal controls in a timely manner. We find that firms with more volatile annual ETR estimates are more likely to report both tax- and nontax-related ICWs in the current year. Our results also indicate that the volatility of annual ETR estimates declines following the remediation of tax-related ICWs, but not following the remediation of nontax-related ICWs. In addition, we find that ETR volatility in the current year is associated with the likelihood that a firm will report an ICW in the following year. Finally, we provide evidence that the volatility of annual ETR estimates is associated with the likelihood that a firm has an undisclosed ICW. In combination, our results suggest that the volatility of interim estimates of the annual ETR provides an ex ante signal of the likelihood that a firm's internal controls are ineffective. 相似文献

AbstractPlaying sports has long been a taboo for women in Colombia, yet new spaces for female participation have emerged in recent decades. This article explores the gendered nature of sport in Colombia through the lived experiences of female participants involved in a local Sport for Development and Peace organization. Building on ethnographic fieldwork and a decolonial feminist perspective, the authors examine how cultural experiences of physicality are gendered but are potentially changing in the context of leisure practices and how this may shape power relations. Although more girls and women are participating in masculine leisure pursuits, there are critical limitations to social change and female participants demonstrate the coloniality of gender in action. 相似文献

Financial self-efficacy (FSE) is a psychological trait that has significant influence over a wide array of financial behavior—from credit market participation to saving and investing behavior. Research has provided consistent evidence that suggests higher FSE supports prudent and growth-oriented financial behavior across a variety of samples. For older adults, FSE has been shown to be weak and susceptible to decline, which is concerning because older adults need to save significantly for retirement, with little time to do so. While research has provided some insight into the sociodemographic and economic factors related to FSE (e.g., income), little is understood about the psychological factors that contribute to FSE levels. Consequently, the authors investigate how psychological characteristics shape FSE within a sample of 2,068?U.S. preretirees from the Health and Retirement Study. Results revealed that FSE can be supported through frequent positive affect, reduced negative affect, stronger mastery beliefs, and a higher task orientation. With this knowledge, financial professionals can more effectively help support older preretirees’ FSE and ultimately, their ability to prepare financially for retirement. 相似文献

This paper presents a comparative study of the shift in community perceptions pre- and post-siting of a biosolids processing facility – the Organic Material Recovery Centre – in the rural Township of Southgate, Ontario. The study responds to the need for comparative studies examining residents’ perceptions of contested noxious facilities during acrimonious siting processes and later during facility operations. Interviews were conducted before and after the techno-industrial facility was sited to compare community perceptions of the proposed and operational facility, and further examine residents’ experiences with residual impacts and reflections on the siting process. Results reveal that once the facility began operations and residents had the opportunity to understand its operational mandate and directions, many residents seem to accept the facility as less threatening to well-being, quality of life and core values. Nonetheless, sustained community concerns shifted to invisible impacts and long-term uncertainty. Findings highlight lingering intra-community conflict between those supporting and those who remained concerned about negative impacts. As a result of the hostile community conflict, the local politics seems to have morphed into a ‘one-issue’ political scene, whereby all issues are divided along the lines of municipal councillors opinions of the facility These findings make methodological contributions with pre- and post-siting comparative qualitative research and contribute theoretically to our understanding of residents’ reappraisal of contested noxious techno-industrial facilities, show sustained divisive social impacts within the community, and call for meaningful consultation and increased participatory siting processes that accounts for the diversity of values and expectations during facility siting. 相似文献

Zero‐inflated ordered probit (ZIOP) and middle‐inflated ordered probit (MIOP) models are finding increasing favour in the discrete choice literature. We propose generalizations to these models – which collapse to their ZIOP/MIOP counterparts under a set of simple parameter restrictions – with respect to the inflation process. These generalizations form the basis of a new specification test of the inflation process in ZIOP and MIOP models. Support for our generalization framework is principally demonstrated by revisiting a key ZIOP application from the economics literature, and reinforced by the reassessment of an important MIOP application from political science. Our specification test supports the generalized models over the original ZIOP/MIOP ones, suggesting an important role for it in modelling zero‐ and middle‐inflation processes. 相似文献

U.S. firms recorded an unprecedented number of asset impairments during the recent financial crisis. We investigate the timing of these losses in the context of two competing views on how firms use discretion over asset impairments. The first view posits that firms record impairments to convey private information as part of their commitment to a conditionally conservative reporting strategy. The second view argues that firms use their discretion to report opportunistically by delaying the recording of bad news. Consistent with the first view, we find that firms recorded timelier asset impairments during the financial crisis if they reported more conservatively in the five years preceding the crisis. Further tests show this relation is greater for firms with strong corporate governance, industry‐specialist auditors, and high leverage, indicating the importance of monitoring mechanisms in determining how firms handle the discretion involved in impairment decisions. We also test for the consequences of timely asset impairments during the financial crisis and find that firms reporting conservatively both before and during the crisis were able to acquire more debt financing, and their publicly traded bonds suffered smaller increases in illiquidity. Collectively, our study highlights the role of asset impairments in firms’ accounting choices over time. 相似文献

Using takeover bids from the United States, we investigate the importance of information asymmetry in self-selection when evaluating the abnormal returns of financial versus strategic takeover targets during a period of possible informed trade. Sample selection bias due to differences in financial versus strategic takeover bid information environments is controlled for using Heckman's model. Results show that takeover announcements are not randomised, indicative of timed announcements, and further that private equity firms exhibit lower price impact post-announcement. We conclude that the long-term financial motive of private equity takeovers, coupled with higher private information pre-announcement, leads to lower abnormal returns post-announcement. 相似文献

Dado que las estadísticas sobre el trabajo infantil condicionan la asignación de las ayudas destinadas a los niños vulnerables, es importante asegurar su correcta medición. La autora investiga si el tipo de encuestado explica las variaciones estadísticas. Según los datos de dos distritos de Tanzanía, el encuestado influye en las estimaciones sobre la prevalencia del trabajo infantil, que aumenta entre un 35 y un 65 por ciento cuando son los propios niños, y no terceros, quienes informan. Entre el 14 y el 31 por ciento de la muestra presenta este sesgo, según el indicador. Las discrepancias disminuyen en relación inversa a la edad del niño y aumentan si el tercero manifiesta una actitud opuesta al trabajo infantil. 相似文献
