“Cruising” infants can only walk using external support to augment their balance. We examined cruisers' understanding of support for upright locomotion under four conditions: cruising over a wooden handrail at chest height, a large gap in the handrail, a wobbly unstable handrail, and an ill‐positioned low handrail. Infants distinguished among the support properties of the handrails with differential attempts to cruise and handrail‐specific forms of haptic exploration and gait modifications. They consistently attempted the wood handrail, rarely attempted the gap, and occasionally attempted the low and wobbly handrails. On the wood and gap handrails, attempt rates matched the probability of cruising successfully, but on the low and wobbly handrails, attempt rates under‐ and overestimated the probability of success, respectively. Haptic exploration was most frequent and varied on the wobbly handrail, and gait modifications—including previously undocumented “knee cruising”—were most frequent and effective on the low handrail. Results are discussed in terms of developmental changes in the meaning of support. 相似文献

This paper investigates the influence of accounting standards on systematic earnings understatement. To isolate the effect
of reporting regulations from those of other institutional drivers of earnings management, Holthausen (2003) proposes analyzing
reporting practices in a country undergoing a transition in accounting standards. We respond to this call by analyzing earnings
management practices of large German-listed companies before and after their transitions from German GAAP to IFRS. Specifically,
we focus on Big Bath behavior following Chief Financial Officer turnovers between 1999 and 2006. Our findings provide evidence
of the effect of accounting standards on the existence of this particular earnings understatement pattern. However, while
we detect Big Bath behavior for our sample of German GAAP firms, we find no such indication for those firms reporting under
IFRS. Controlling for alternative explanations such as self-selection bias does not change our findings. We conclude that
accounting standards seem to have a considerable influence on earnings management behavior, independent of managers’ and auditors’
incentives. 相似文献

The current economic climate demands more innovative approaches to increasing labor market participation for people with disabilities. Social entrepreneurship (SE) offers one alternative employment pathway. However, little is known about the broader factors influencing SE for people with disabilities. Using empirical data from focus groups comprised of social entrepreneurs with disabilities and interviews with key stakeholders working in the fields of policy, disability, and business, this research frames its analysis in the intersection of disability studies and entrepreneurship to explore which factors influence the potential for SE to provide equal participation opportunities for people with disabilities in the labor market. Findings suggest that further consideration of political–economic and socio-cultural factors is needed if we are to better understand the potential of SE for people with disabilities. 相似文献

Given the proliferation of pornography in personal, relational, and social realms, it is vital to understand women’s experiences of this accessible, stimulating, and versatile sexual material. We therefore conducted the first systematic review of research using qualitative methods published in English in peer-reviewed journals. Our search of five databases yielded 22 eligible articles. Thematic analysis of results revealed four broad themes: women encountering pornography, pornography and the self, pornography in the context of relationships, and making sense of pornography. Discussion of themes and subthemes included reflections on women’s explanations of intentional and unintentional encounters with pornography, conflicted perceptions of themselves in relation to female pornography actors, diverse perceived effects of pornography on intimate relationships, and tensions between women’s arousal to pornography and their values. It was evident that women’s experiences of pornography are complex and nuanced, often paradoxical, varying among and within individuals. Our synthesis of results and assessment of limitations suggest (a) that researchers need to define what they mean by pornography and specify any content used in their research and (b) that understanding would be enriched by research that is culturally contextualized and acknowledges public discourses about pornography. 相似文献

This paper uses longitudinal data from the Philippines to analyze determinants of children’s time allocation. The estimation method takes into account both the simultaneity of time use decisions, by allowing for correlation of residuals across time uses, and unobservable family heterogeneity, through the inclusion of household fixed effects. Importantly, this improved estimation method leads to different results than when applying the methods previously used in the literature. Girls suffer significantly from the absence of their mother with a reduction in time spent in school that is equivalent to dropping out completely. This effect is substantially larger when controlling for household unobservables than when not. Boys increase time spent working on market related activities in response to an absent father, although this time appears to come out of leisure rather than school or doing household chores. Land ownership substantially increase the time boys spend on school activities, whereas renting land reduces the time girls spend on school. Finally, there does not appear to be a substantial trade-off between time spent on school and work, either in the market or at home. 相似文献

Sensory judgments have always been a part of medical practice, as sensory studies scholars have emphasized. However, in current regulatory, management and technological contexts, there is a push toward rational decision-making procedures and test-based evidence over clinical diagnosis. Sociological scholarship highlights that in focusing on explicit medical knowledge and disembodied data we take for granted aspects of healthcare work, including the ways in which health and illness is sensed. Research in sociologies of diagnosis and social studies of science and technology has captured that while the senses continue to play a role in medical work, the status and practice of this sensory work is not straightforward as evidenced by dual use of the senses and tests and the delegation of sensory work. Based on semi-structured interviews with expert doctors in diverse specialties, this article examines the sensory work of medical decision-making, with attention to its legitimacy. It examines applications of the senses from auscultation to ongoing sensing of patients’ bodies unmediated and via technological outputs. While critical to clinical judgments, there is discomfort with this sensory work in light of medico-legal pressures. I argue that the sensory work of diagnosis is vital, to the extent that gaps in sensory information imply gaps in understanding. 相似文献

BackgroundSevere perineal tears sustained during childbirth cause significant distress and morbidity amongst women. The objective of this study was to compare the use of straight scissors for cutting an episiotomy with the use of curved scissors, which are designed to curve away from the anal sphincter.MethodsWe used a single-centre, randomised feasibility trial. The intervention was the use of curved scissors. Women were recruited during a prenatal visit and randomised in the delivery suite, when it became clear that an episiotomy was required. The feasibility outcomes were the proportion of women able to be recruited, randomised and followed up. We also calculated the incidence of obstetric anal sphincter injury when either straight or curved scissors were used to cut an episiotomy. Other outcomes assessed were pain, length of hospital stay, perineal infection and perineal dehiscence.ResultsOf the 155 patients recruited in the prenatal period, only 20 (12.9%) were eventually randomised at birth. The main reasons for the high loss were that women either did not have a vaginal delivery (38, 24.5%), or they did not need an episiotomy (72, 46.5%). Rates of obstetric anal sphincter injury and other outcomes were similar between groups.DiscussionAnal sphincter injury during childbirth remains an important problem. Although the use of curved scissors provides a theoretical solution, we found that the high attrition rate made feasibility of conducting a suitably powered, randomised trial using the current design untenable. Alternative strategies have been suggested to make any future study more viable. 相似文献

Normalizing Denominational Statistics with Demographic Data: The Case of the United Church of Canada
Sarah Wilkins‐Laflamme 《Revue canadienne de sociologie》2012,49(2):173-187
In the Canadian context, one type of data has been underutilized in the study of contemporary religious trends: church collected statistics. The present article explores the advantages and limitations of such data by analyzing the evolution of key church indicators of the United Church of Canada over the past four decades. Figures regarding church membership, child baptisms, and funerals are examined and compared with demographic data from four Canadian regions. Results show that virtually all United Church statistics are in decline with regard to larger society since the 1970s. However, there are regional variations, most notably in the Atlantic provinces, which show later and lesser rates of decline. 相似文献
