Near-miss outcomes during gambling are non-win outcomes that fall close to a pay-out. While objectively equivalent to an outright
miss, near-misses motivate ongoing play and may therefore be implicated in the development of disordered gambling. Given naturalistic
data showing increases in heart rate (HR) and electrodermal activity (EDA) during periods of real gambling play, we sought
to explore the phasic impact of win, near-miss and full-miss outcomes on physiological arousal in a controlled laboratory
environment. EDA and HR were monitored as healthy, student participants (n = 33) played a simulated slot-machine task involving
unpredictable monetary wins. A second gambling distortion, perceived personal control, was manipulated within the same task
by allowing the participant to select the play icon on some trials, and having the computer automatically select the play
icon on other trials. Near-misses were rated as less pleasant than full-misses. However, on trials that involved personal
choice, near-misses produced higher ratings of ‘continue to play’ than full-misses. Winning outcomes were associated with
phasic EDA responses that did not vary with personal choice. Compared to full-misses, near-miss outcomes also elicited an
EDA increase, which was greater on personal choice trials. Near-misses were also associated with greater HR acceleration than
other outcomes. Near-miss outcomes are capable of eliciting phasic changes in physiological arousal consistent with a state
of subjective excitement, despite their objective non-win status. 相似文献

Households with limited income and wealth often struggle to access the financial liquidity needed to address unexpected expenses or income drops. Emergency savings can act as form of insurance against such economic shocks and reduce the risk of hardships that influence family wellbeing. Prior research has established that threshold amounts of liquid assets can reduce the risk of economic hardship. This study used a measure of self-reported emergency saving behavior to examine whether households who reported saving for emergencies were less likely to experience subsequent economic hardships in a longitudinal sample of households in disadvantaged neighborhoods from the Annie E. Casey Foundation’s Making Connections project. Results across a range of regression models suggest that households who saved for emergencies experienced slightly less overall hardship and were less likely to report several specific hardships, such as food insecurity and having a phone disconnected, three years later. This study supports the idea that small, unrestricted savings may play a protective role for low-income households. 相似文献

Relations Between Alphabetized Name Order and Nomination Counts in Peer Nomination Measures 下载免费PDF全文
Peer nominations, a central method for measuring peer relationships in developmental research, typically involve asking children or adolescents to choose peers who fit various criteria from an alphabetized roster of classmates or grade‐mates. Although such measures have been used for decades, very little research has investigated the effects of alphabetical name order on the number of nominations received by peers. This study collected peer nominations for 20 items among 607 eighth grade participants in two schools. Regression analyses showed that earlier name order significantly predicted higher nomination counts for eight of the items, and explained over 5 percent of the variance in four affective variables (friendship, acceptance, acquaintanceship, and received liking). Across variables, name order effects were negatively correlated with internal reliability of nominations, implying that order effects may be related to the consensus of the peer group. Name order also had a minimal effect on inter‐correlations among a subset of variables. Implications and concrete recommendations for controlling and reducing name order effects in future research are discussed. 相似文献

This study contributes to earlier research on homeownership and childbearing by taking into account the potential simultaneity between these two life events. A dataset comprising three different Swedish birth cohorts suggests that these are events that are indeed simultaneous. Different tests indicate that taking this simultaneity into account gives an overall statistically significant improvement of the model fit. However, this result is most obvious for those young adults who faced increasing problems on the housing market. The childbearing decision of these cohorts also seems to be more sensitive to changes in the user cost. 相似文献

Among policymakers, a common perception surrounding the effects of cash transfer programmes, particularly unconditional programmes targeted to families with children, is that they induce increased fertility. We evaluate the Zambian Child Grant Programme, a government unconditional cash transfer targeted to families with a child under the age of 5 and examine impacts on fertility and household composition. The evaluation was a cluster randomized control trial, with data collected over 4 years from 2010 to 2014. Our results indicate that there are no programme impacts on overall fertility. Our results contribute to a small evidence base demonstrating that there are no unintended incentives related to fertility due to cash transfers. 相似文献

The role of urban expansion on bee diversity is poorly understood, but it may play an important role in restructuring pollinator diversity observed in rural regions at the urban perimeter. We studied bee communities in two habitats essential for pollinators (residential gardens and semi-natural areas) at 42 sites situated at the edge of greater Montreal, Canada. Bee species richness, abundance and functional diversity all increased with urbanization in both habitat types, but gardens and semi-natural areas supported distinct bee communities with unique responses to urbanization in terms of species turnover. Compared to semi-natural sites, residential gardens supported bees that foraged from a greater number but a lower proportion of available plant species. Bees did not discriminate between exotic and indigenous plant species in either gardens or semi-natural sites and were attracted to flowers in either habitat irrespective of their origins. Protecting semi-natural ruderal areas and providing residential garden habitats for pollinators are both effective means of promoting regional bee diversity in urbanizing regions. 相似文献

In contrast to the common tendency to see war as the result of leadership decisions based on risk assessments, and political and economic considerations about gains or losses, we use a constructivist and institutional perspective to historicize and politicize the way “nation‐state interests” and “nation‐state preferences” even in a decision to go to war are socially constructed and culturally embedded. We maintain that with the end of the Cold War, many societies found themselves at a crossroads where they had to resolve internal conflicts in regards to neoliberal globalization. These internal conflicts and a crisis of identity, between those who supported the principle of globalization and regarded it as a promise for democracy, openness, liberty and peace, and those who saw it as a danger to their exceptionality and distinctiveness, ended in wars (either internal wars or external wars) when the objectors of neoliberal globalization succeeded in creating an institutional turn which presented war as the “efficient,” “necessary,” “legitimate”, or “desired” solution to the new threatening reality. We demonstrate the validity of this argument by using Israel as a test case, examining how institutional changes in the 1990s, arising from internal societal conflicts around the Oslo Agreements, led the state to move from the brink of peace to new wars despite exogenous objections to its policy. 相似文献
