The way that nonprofits respond to funding uncertainty is crucial to their ability to meet goals and position themselves for future success. This article investigates how structural, managerial, and financial characteristics affect the adaptive tactics used by human service nonprofits during times of financial stress. These tactics include adding new programs, reducing programs or staff, expanding or starting joint programs, pursuing earned income, and expanding advocacy involvement. Using longitudinal data on human service nonprofits collected on either side of the 2002–2003 economic downtown, we find that larger size provides organizations with a unique ability to choose among different adaptive tactics, as larger size was significantly predictive of adding new programs, reducing programs, expanding advocacy, and pursuing earned income. Strategic planning was positively associated with innovative tactics such as starting joint programs or pursuing earned income. Financial stress or declines in an organization's major funding source led to cutbacks, as expected, but managers who foresaw these challenges were able to respond proactively by adding programs or starting joint programs. However, managers with more training did not respond much differently than did other managers, and organizational age and use of performance management tools had no effect in guiding organizational responses to financial uncertainty.  相似文献

The fast aging of many western and eastern societies and their increasing reliance on information technology create a compelling need to reconsider older users' interactions with computers. This paper summarizes the results of 6 years of research on the age-differentiated design of human-computer interaction. The well-known model of human information processing served as the theoretical framework. The model components 'sensory processing', 'perception', 'working memory', 'decision and response selection' and 'response execution' were analyzed exemplarily in task settings on project management. In seven empirical studies with a total number of 405 participants between 20 and 77 years the human-computer interaction was analyzed regarding effectiveness, efficiency and user satisfaction. For most but not all studies the results reveal that age-induced differences in human-computer interaction can best be compensated by an ergonomic 'design for all'. In some cases however an age-specific approach is favorable.  相似文献

This article presents results obtained from some ergonomics intervention in the project for the conception of aircraft's cabins. The study's aim is to analyze the contribution of the method adopted in the passengers' activities analysis in reference situations, real-use situations in aircraft's cabins, applied to analyze typical activities performed by people in their own environment. Within this perspective, the study shows two analyses which highlight the use of electronic device. The first analysis has been registered through a shooting filming in a real commercial flight. In the second one, the use is developed within the domestic environment. The same method has been applied in both contexts and it is based on activity analysis. Starting with the filming activity, postures and actions analysis, self-confrontation interviews, action course reconstruction and elaboration of postures envelopes. The results point out that the developed method might be applied to different contexts, evincing different ways of space occupation to meet human personal needs while performing an activity, which can help us with the anticipation of the users' needs, as well as indicate some innovation possibilities.  相似文献

Comfort is an issue that has gained relevance within the aeronautical industry due to the necessity of manufacturers and airline companies of differentiating themselves in a market that has become more and more competitive each day. This study's aim is to analyze the comfort/discomfort of passengers, based on the analysis of the activities performed in the aircrafts' cabin during real flights, in order to create ergonomics requirements and a methodology of comfort analysis. The study has been performed during domestic commercial flights, and the adopted data collection techniques have been: the application of 219 questionnaires to passengers, 44 registrations of postures and actions through filmings and 12 semistructured interviews. The method has made possible the reconstruction of the user's action course in performing activities in real flight situations, and the calculation of the area occupied by the passenger during his or her actions. The integrated analysis of the results corroborates data from previous studies in which both the space made available to each passenger and the activity performed interfere in their perception of comfort. From this study it has been concluded that the method constitutes itself as an innovative tool within the process of aircrafts' cabins project enabling the calculation of the action space based on the reconstructed course.  相似文献

Many scholars pinpoint the family as one of the most important loci of class differences and see parenting in particular as a mechanism for the reinforcement and reproduction of class variation. In this article, the authors explore the role of educational background, occupations, family resources, state surveillance, and culture in explaining how and why parenting practices vary by class backgrounds. The article reviews research that focuses on class‐based cultural norms and values, as well as research that argues that structural conditions and access to resources are more important than culture in influencing parenting norms, beliefs, and outcomes. The authors then discuss recent research that suggests that rather than seeing culture and structure as dichotomous, in fact, culture and structure are intertwined and it is through seeing them as mutually reinforcing factors that we can best make sense of class‐related parenting differences.  相似文献

Maternal education differences in children's academic skills have been strongly linked to parental investment behaviors. This study extended this line of research to investigate whether these same maternal education patterns in parenting are observed among a set of parenting behaviors that are linked to young children's health. Drawing on data from the Early Childhood Longitudinal Study, Birth Cohort (n = 5,000) and longitudinal models incorporating random effects, the authors found that higher levels of maternal education were associated with more advantageous health investment behaviors at each phase of early development (9 months, 2 years, 4 years, 5 years). Moreover, these disparities were typically largest at the developmental stage when it was potentially most sensitive for children's long‐term health and development. These findings provide further evidence of a developmental gradient associated with mothers' education and new insight into the salience of mothers' education for the short‐ and long‐term health and well‐being of their children.  相似文献

The authors examine factors associated with the advancement or dissolution of newly formed sexual relationships. Data from the 2006–2010 National Survey of Family Growth (NSFG) was used to examine women and men aged 18–39 (n = 2,774) whose most recent sexual relationship began within the 12 months before their interview. Results indicate that newly formed sexual relationships are often transitory. By 12 months, only 23% of respondents remained in nonresidential sexual relationships, another 27% were cohabiting with that partner, and half had ended their relationships. Sexual relationships formed before age 25 are significantly more likely to break up than to transition into cohabitation. Indicators of social class disadvantage, such as living with a stepparent, expedited cohabitation, whereas measures of advantage, such as having a college‐educated mother, deterred transitions into shared living. Racial differences also emerge: Blacks were less likely than Whites to transition rapidly into shared living.  相似文献

This article aims to broaden the ways we conceptualize citizenship and implement citizenship education in social studies. To do so, the authors explore media texts as a curricular and pedagogical site for teaching lessons about citizenship. Specifically, the authors investigate how media drafts the boundaries of citizenship for Latin@ youth, and influences how young people come to understand who is and who is not perceived as a citizen entitled to rights and freedoms. Media texts, like formal social studies curricula, are powerful and enduring educators that shape how students know the world and imagine their place in it. Therefore, this article addresses how social studies teachers can integrate media texts into the classroom to explore representations of Latin@s and the impact that media has on our citizenship identities and experiences.  相似文献
