In a complex social environment, stimuli from different sensory modalities need to be integrated to decode communicative meanings. From very early in life, infants have to combine a multitude of sensory features with social and affective attributes. Of all senses, touch constitutes a privileged channel to carry affective-motivational meanings and foster social connection. In the present study, we investigate whether sharing sensory stimulation that varies for its affective value differentially affects infants' attention towards visual stimuli. 6 to 11-month-old infants (N = 42) were familiarized with two characters respectively matched with tactile (affective or non-affective) and auditory stimulation; then repeatedly exposed to scenes where the two characters moved towards target objects. Our results showed a main effect of stimulation (sound vs. touch) on looking times during familiarization, with longer looking times when sound is provided. During scenes presentation, a main effect of the type of touch (affective vs. non affective) emerged, with longer looking times in infants that previously experienced affective touch, suggesting that this sensory experience may critically engage the self and modulate infant attention. Overall, these findings suggest that while sound acts as attention getter, affective touch supports sustained attention towards complex visual scenes beyond the stimulation period itself.  相似文献

Communities are concerned over pollution levels and seek methods to systematically identify and prioritize the environmental stressors in their communities. Geographic information system (GIS) maps of environmental information can be useful tools for communities in their assessment of environmental‐pollution‐related risks. Databases and mapping tools that supply community‐level estimates of ambient concentrations of hazardous pollutants, risk, and potential health impacts can provide relevant information for communities to understand, identify, and prioritize potential exposures and risk from multiple sources. An assessment of existing databases and mapping tools was conducted as part of this study to explore the utility of publicly available databases, and three of these databases were selected for use in a community‐level GIS mapping application. Queried data from the U.S. EPA's National‐Scale Air Toxics Assessment, Air Quality System, and National Emissions Inventory were mapped at the appropriate spatial and temporal resolutions for identifying risks of exposure to air pollutants in two communities. The maps combine monitored and model‐simulated pollutant and health risk estimates, along with local survey results, to assist communities with the identification of potential exposure sources and pollution hot spots. Findings from this case study analysis will provide information to advance the development of new tools to assist communities with environmental risk assessments and hazard prioritization.  相似文献

This paper examines gender differences in out-marriage rates in the United States among 16 race and ethnic groups. Among most groups of Asian Americans, females are more likely to marry whites than are their male counterparts, the reverse of the pattern among African Americans discussed by Merton (1941). We find some Hispanic-American groups in both camps. We explore whether the greater contact between white U.S. military personnel in Asian countries explains the pattern of Asian white marriages. We also introduce a new statistical approach that facilitates comparisons across multiple race and ethnic groups. Data from the 1% sample of the 1990 Census are analyzed in this study.  相似文献

Effective measurement of information system (IS) success continues to be a top concern for both practitioners and researchers. Labeled the “productivity paradox”, previous attempts to quantify the benefits of IS have often resulted in inconclusive or inconsistent results. The present study contributes to IS success research through the development and empirical testing of a process-oriented model of IS success. Using an operational perspective and combining primary and secondary measures, this study examines the influence of lower-level intangible IS and information technology (IT) benefits on higher-level financial measures. Additionally, we introduce IS plan quality as an antecedent to the model's input variables. Primary survey data from CIOs of primarily Fortune 2000 size firms are combined with secondary data, total operational cost, from Compustat to facilitate the examination of the IS benefits. This study also addresses shortcomings cited in other studies that might have contributed to the productivity paradox by including control variables in the model, defining a research perspective—the operational success perspective—and clearly articulating the level of analysis as the organizational level. The results supported a process-oriented view of the benefits from IS and showed how the effects of IS along a path can lead to better organizational performance, in this case, lower overall costs. These results are discussed and future research implications are presented.  相似文献

This paper examines issues of democratic accountability as they apply to faith-based organizations cooperating in international developmental efforts, with a specific focus on the freedom of expression rights of nonprofit organizations and the freedom of association rights of their clientele. Child welfare nongovernmental organizations (NGOs) in Romania are used as a case study for examining the issue. The paper begins with a discussion of NGO-government partnerships in service provision in international development, and examines the ethical concerns surrounding church-state separation as applied to nonprofits in the United States and in the context of foreign aid. The literature analysis is complimented by empirical evidence from the Romanian case, using data gathered in a qualitative study exploring the role of NGOs as social service providers and policy advocates. The paper concludes by discussing the particular role that bureaucratic discretion and power plays in protecting the freedom of association rights of clientele in Romania.  相似文献

This paper explores the experiences of social work students on qualifying degree programmes in the UK who have previously been in care or ‘looked after’. Using a sample drawn from three social work programmes in the North West of England, a semi-structured interview schedule was constructed, with the support of social workers who had been in the care system, to examine the individual journeys of 11 students. This paper aims to explore, with this group of students, how their experiences relate to their decision to apply for a place on a social work course, their experience of admission and the duration of the programme. The paper is of particular relevance to social work educators and makes specific suggestions regarding how current practice in social work education might improve.  相似文献

The study contextualises the position of child citizens in the South African democracy and highlights how education for democratic citizenship is employed through a literacy‐based approach. The qualitative study was exploratory and based on a lesson presented to nine‐year‐old township children by giving them language‐related tasks. Through the children's voices we present the life experiences that expressed their need for basic services, education, extra facilities and security. We argue that children need to experience the benefits of democracy and education for democratic citizenship to build and sustain a resilient democratic society.  相似文献

The present study deals with lay conceptions of well-being and its main determinants, and the rules used by everyday people to assess the well-being of others based on various pieces of information. The results showed that (a) most proposed definitions of well-being refer to the family, the physical body, and acceptance of oneself and one's situation; (b) the factors with the greatest impact on judgments of the well-being of others are health, harmony with spouse, harmony with children, self-acceptance, positive relations, purpose in life, and personal growth; (c) the above findings apply to respondents of all ages; and (d) the information integration rule for estimating the level of the well-being is essentially additive.  相似文献
