According to revisionist historians and American Indian activists,Christopher Columbus deserves condemnation for having broughtslavery, disease, and death to America’s indigenous peoples.We ask whether the general public’s beliefs about Columbusshow signs of reflecting these critical accounts, which increasedmarkedly as the 1992 Quincentenary approached. Our nationalsurveys, using several different question wordings, indicatethat most Americans continue to admire Columbus because, astradition puts it, "he discovered America," though only a smallnumber of mainly older respondents speak of him in the heroicterms common in earlier years. At the same time, the percentageof Americans who reject traditional beliefs about Columbus isalso small and is divided between those who simply acknowledgethe priority of Indians as the "First Americans" and those whogo further to view Columbus as a villain. The latter group ofrespondents, we find, show a critical stance toward modal Americanbeliefs much more broadly. We also analyze American history school textbooks for evidenceof influence from revisionist writings, and we consider representationsof Columbus in the mass media as well. Revisionist history canbe seen as one consequence of the "minority rights revolution"that began after World War II and has achieved considerablesuccess, but the endurance of Columbus’s reputation—toa considerable extent even among the minorities who have theleast reason to respect him—raises important questionsabout the inertia of tradition, the politics of collective memory,and the difference between elite and popular beliefs.  相似文献

For the planning of community tuberculosis, prophylaxis one must know the prevalence of tuberculosis (TB) infection as a function of response to the Mantoux intradermal tuberculin test; the standard test for indicating Mycobacterium TB infection. The skin induration size used to select individuals for prophylaxis must be chosen carefully, in view of the costs associated with carrying out and supervising such prophylaxis. The Mantoux test was used to obtain measurements on adolescents in metropolitan Victoria and on a small sample of adolescents with clinical TB. These data are employed to obtain estimates and to construct upper confidence bounds for the conditional probability of TB infection, given the level of Mantoux response. Two conservative methods are presented; one is ‘nonparametric’, the other ‘semiparametric’. The analyses indicate that for responses up to and including 13 mm, the probability of TB infection is less than.07 with ninety-five percent confidence.  相似文献

The issue has been raised previously that the use of the correlation or squared correlation as an estimate of determination depends on the type of model that is considered (Ozer, 1985). We identify three models of subjective well-being and show that the respective estimates of determination require different interpretations of the correlation statistic. The differences are illustrated using data from the Newfoundland Longitudinal Study of Aging. (NLSA).  相似文献

Wealth inequality between the top and bottom deciles has grown over the last 20 years (Piketty and Zucman in Wealth and inheritance in the long run, Centre for Economic Policy Research, London, 2014), as has the racial wealth gap (Shapiro et al. in The roots of the widening racial wealth gap: explaining the black–white economic divide. Institute on Assets and Social Policy, Brandeis University, Waltham, 2013. http://iasp.brandeis.edu/pdfs/Author/shapiro-thomas-m/racialwealthgapbrief.pdf). Within these broad trends of inequality, some families are able to get ahead and grow their wealth, while others are not. Yet we do not understand well the critical variables that increase the likelihood of wealth mobility across the life course—within the same generation. This paper addresses this gap and investigates the following questions: What accounts for intra-generational relative and absolute wealth mobility for families with children in the first decade of the twenty-first century? And how does it differ by race? The paper draws on two longitudinal data sets—the Panel Study of Income Dynamics household survey data matched with neighborhood-level US Census data (1999–2011), and the IASP Leveraging Mobility (LM) study (1998–2011). Applying an integrated mixed methods design, analyses are conducted in three stages: (1) A grounded theory analytic approach of the LM data determines key variables of wealth mobility: homeownership, income, employment characteristics, extended family wealth, negative life events, and neighborhood factors; (2) regression analyses test these indicators for absolute and relative wealth mobility; and (3) recontextualization through further analyses of LM data deepen the regression results by illustrating the pathways of significant wealth mobility predictors. Results reveal that increasing family income, larger family transfers, consistent long-term homeownership, and in some cases white-collar occupations increase the likelihood of upward relative wealth mobility. Negative life events, higher rates of neighborhood poverty, and black race are negatively correlated with the amount of wealth growth. These key drivers of wealth mobility highlight the need for targeted policies that reinforce and expand opportunities for all families to build wealth over the life course.  相似文献

In 2020, Australia's successful COVID-19 public health restrictions comprised a national “initial lockdown” (March–May) and “ongoing lockdown” (July–November) for metropolitan Victorian residents only. We evaluated associations between ongoing lockdown and family finances and mental health. In the June and September 2020 Royal Children's Hospital National Child Health Polls, caregivers of children in Victoria and New South Wales (NSW) reported the following: job/income loss; material deprivation (inability to pay for essential items); income poverty; mental health (Kessler-6); perceived impact on caregiver/child mental health; and caregiver/child coping. Data from caregivers (N = 1207/902) in June/September were analysed using difference-in-difference modelling (NSW provided the comparator). During Victoria's ongoing lockdown, job/income loss increased by 11% (95%CI: 3%–18%); Kessler-6 poor mental health by 6% (95%CI: −0.3%–12%) and perceived negative mental health impacts by 14% for caregivers (95%CI: 6%–23%) and 12% for children (95%CI: 4%–20%). Female (vs. male) caregivers, metropolitan (vs. regional/rural) families, and families with elementary school-aged children (vs. pre-/high-school) were the most affected. The ongoing lockdown was associated with negative experiences of mental health, employment and income, but not deprivation or poverty, likely because of government income supplements introduced early in the pandemic. Future lockdowns require planned responses to outbreaks and evidence-informed financial and mental health supports.  相似文献

This paper presents the findings from a qualitative study that sought to understand the experiences of frontline staff working in Oxfordshire County Council (OCC) Children's Social Care Services and their views on a new family safeguarding model (Family Solutions Plus). Focus group interviews were conducted with 20 frontline staff and managers in different teams across OCC Children's Social Care Services using video conferencing software. Thematic analysis identified three overarching themes: Preparation for the implementation of Family Solutions Plus, staff views on the implemented model, and challenges to its implementation. Staff voiced strong support for the new model, which places a much greater emphasis than previous practice on supporting the whole family, developing parenting skills and keeping children safe with their families. The challenges associated with the transition to a new model were considerable in the short term, partly due to the COVID-19 pandemic, but there was optimism that the new model could be sustained and stabilized over time.  相似文献

Introduction

Stand your ground (SYG) and castle doctrine (CD) laws are presently growing throughout the United States. The present study aims to better understand public perceptions of SYG and CD cases and demographic factors that influence judicial decision making.

Methods

Participants were 204 adults who were randomly assigned one of four vignettes that depicted a CD or SYG scenario and varied by defendant demographics. After reading the vignette, participants completed a questionnaire assessing whether they believed the defendant was guilty of the murder and whether the homicide was justified.

Results

Results indicated participants were more likely to assign a guilty verdict to the SYG scenario, compared to the CD scenario. Additionally, participants assigned to the SYG vignette believed the male defendant was more justified in killing the victim, compared to participants assigned the female defendant.

Conclusion

Results from this study reveal how potential jurors may harbor sex/gender bias in determining justifiable homicide in stand your ground cases.  相似文献

Production in knowledge and data-intensive industries is powered by work that can, in theory, be done from anywhere, via cloudwork platforms. Cloudwork platforms govern data value chains in distinct ways to concentrate power and extract value at the global scale. We argue that unpaid labour is a systemic mechanism of accumulation in these digital value networks. In this paper we demonstrate how it is tied to platform business models and facilitated by elements of platform governance including monopsony power, a high degree of spatial flexibility in sourcing labour, regulatory unaccountability and digital enclosure. We draw on a survey of 699 workers on 14 platforms in 74 countries to show that unpaid labour is an engine of South–North value extraction, and workers in the global South perform more unpaid labour than counterparts in the global North. Our findings have important ramifications our understanding of the changing international division of labour and platform capitalism.  相似文献
