This study investigates the perceived impact of election polls,focusing on the hotly contested 2000 U.S. presidential election.Survey data from 558 individuals gathered during the final daysof the election campaign are analyzed to examine beliefs thatthe polls greatly affect other voters, general views of pollsas good or bad for the country, beliefs about whether pollstersinfluence their results to come out a certain way, and supportfor banning election-night projections. Results indicate thatmost respondents felt the polls had no influence on themselveswhile still affecting others. Respondents exhibiting these third-person-effectperceptions were significantly more likely than others to believethat election polls are a bad thing for the country. Negativeperceptions of polls and beliefs that pollsters try to influenceresults were also related to general distrust of the news media.Negative views of polls in turn were associated with increasedsupport for prohibiting election-night projections. In general,the results illustrate the dependency of negative views aboutpolling on fears of untoward effects on voters, in particularthe fear that polls and election projections might lend supportto candidates opposed by the respondent. 相似文献

The protective action of remote ischaemic preconditioning (RIPC) has been demonstrated in the context of surgical interventions in cardiology. Application of RIPC to sports performance has been proposed, but its effect on the electrocardiogram (ECG) during exercise remains unknown. This exploratory study aims to measure the changes in ventricular repolarization observed during exercise following RIPC in healthy subjects. In an experimental randomized crossover study, 17 subjects underwent two bouts of constant load exercise tests at 75% and 115% of gas exchange threshold (GET). Prior to exercise, they were allocated to either control or RIPC intervention with four cycles of 5?min of ischaemia followed by 5?min of reperfusion. ECG was continuously recorded during the protocol. QT and RR intervals were measured every 30?s (on an average tracing of the preceding 10?s). Although the time course of RR intervals did not differ between the two interventions (p?=?.56 at 75% GET and p?=?.74 at 115% GET), a significant shortening of QT intervals (measured from Q onset to T end) was observed during exercise (mean?±?standard deviation of RIPC vs. control: ?32?±?19?ms at 75% GET (p?.001) and ?34?±?12?ms at 115% GET (p?.001)) as well as during recovery (?21?±?8?ms at 75% GET (p?.001) and ?16?±?11?ms at 115% GET (p?.001)). This effect was not present at rest. These RIPC-related changes were clearly identifiable on the QT–RR loops after hysteresis reduction. RIPC therefore induces heart rate-independent shortening of QT intervals that is revealed during exercise. 相似文献

In all parts of the world, the teaching of history, because of its important ideological dimension, tends to be influenced by social and political changes. The recent upheavals in South Africa have confronted the nation with so many new tasks that it is difficult to decide which of them should have priority. These tasks include the establishing of a new educational curriculum which, paradoxically, no longer includes the subject of history as such. Instead, history is subsumed under the human and social sciences. This article analyses the content of history text books from the primary level upwards and from the 1980s to the most recent publications. On this basis it attempts to assess the extent and limits of the changes within a political setting marked by a tension between the historic struggle for equality and justice and the constraints imposed by the functioning of a liberal economy within the context of the globalization of modern capitalism. The considerable changes in the content of these books seem to be based on two different theoretical models: the multicultural model embodied in the idea of the "rainbow nation"; and the notion of the universality of humanity, transcending the diversity of cultures and confirmed by the findings of archaeology. While these two models can be a basis on which to refute racial inequality, they are not used to combat other forms of inequality, in particular social inequality. 相似文献

AN EXPLORATION OF THE EDUCATIONAL RESILIENCE OF TEACHING STAFF – This study focuses on the degree of resilience displayed
by teaching staff with the aim of promoting their professional development and preventing job-related exhaustion. Seven underprivileged
schools in Montreal were selected, and 24 teaching staff with contrasting personal profiles were interviewed on the subject
of their work. The Alceste software was used to analyse the conversations, which revolved around techniques applied when dealing
with critical incidents. The main analysis identified five different discourses among the respondents. Three of these were
associated with the more resilient of the teachers and two were associated with the more vulnerable ones. Resilient teaching
staff characteristically discussed dealing with aggressive behaviour, the teaching-learning relationship and the subject of
social relationships, whereas vulnerable teaching staff focused on work beyond the classroom, people in positions of higher
authority and the community. The authors note that teachers who are just embarking on their careers appear more vulnerable
than more experienced teaching staff, which suggests that more resources should be provided to support teachers in their profession. 相似文献

In general, rhetoric and myth play important roles in policymaking. Myths may inspire collective action but may also mystify and blur views on reality. In this article we identify, analyze, and reflect on the myths underlying the e-government programs of Australia, Canada, the United Kingdom, Denmark, and the Netherlands. We found that in all national policies myths of technological inevitability, a new and better government, rational information planning, and empowerment of the intelligent citizen can be discerned. Although the mobilizing powers of these myths are acknowledged, we conclude that existing empirical studies have generated little support for the inescapable telos of these myths, which makes canvas cleaning effects of e-government initiatives less likely. 相似文献

While long-acting reversible contraception (LARC) reduces risk of repeat-births, use remains low among rural Latinx adolescent mothers. This qualitative study identified perspectives about factors that influence LARC use among this population. Participants were dyads of parenting Latinx adolescent daughters and their mothers (n?=?9 dyads) and nurses (n?=?17). Findings revealed themes specific to this vulnerable population including (a) distinct ways LARC characteristics fit into parenting teenagers’ lives, (b) supportive health care climate toward LARCs, and (c) factors that inhibit LARC uptake. The study has implications for sexuality education that seeks to reduce repeat-births among this population. 相似文献
