There are two behavioral approaches to addiction: rational and irrational. The rational approach assumes that addicts have higher time preference rates and lower risk-aversion coefficients—parameters that are interpreted as impulsive preferences. On the other hand, the irrational approach argues that addiction is a consequence of anomalies such as non-expected utility and hyperbolically discounted utility. This paper integrates these two approaches and concludes that anomaly and impulsivity complementarily account for addiction.  相似文献

ABSTRACT

This article traces the ways that gendered and generational family practices were remembered across time in the context of working-class homes in Victorian Britain. Two everyday domestic objects—the father's chair and the grandfather clock—are examined and analyzed, drawing on John Gillis' work on ritualized family spaces and contested notions of time (Gillis 1996). Both these objects resonate with the contested use of domestic space and the layered meanings of family time in working-class lives, not least because both are often remembered in autobiographical accounts of home and family. The special place of the father's chair highlighted the feminizing of the home and accompanying development of rituals to welcome and ensconce the father in his domestic domain each day. The sound of clocks underpinned the bringing together of industrial time, separating leisure and work for those at school or employment away from home, and at the same time conveying the cyclical nature of family life and its everyday routines from day to day, year to year, and generation to generation. Memories of chairs and clocks embedded in autobiographies offer important evidence about the images, sounds, and sensory experiences that resonated most powerfully when remembering and composing the hierarchies and tensions of working-class family life.  相似文献

Abstract Partly because of the field's efforts to deal first with the kinds of impacts that have been the most obvious and pressing, the traditional focus of social impact assessment has been on the impacts taking place during the most intensive phases of developmental activity. Recently it has become increasingly clear that a number of predictable, significant impacts take place both before and after the periods of most intense activity; these impacts are missed by social impact assessment approaches that are excessively narrow in focus. This paper offers a conceptual framework that is relatively simple but that deals with impacts both across time and across potentially affected systems of the human environment, doing so in such a way as to improve the promise of social impact assessment to become more nearly comprehensive.  相似文献

This article develops and empirically tests a model of the dual decision-making process employees undergo to guide their behavior during organizing campaigns and elections. The model combines principles of risk-aversion theory with more traditional views that election decisions stem from cost-benefit analyses of union representation. Previous research lacks this integrated approach to the study of election behavior. Regression analyses on a sample of approximately 16,000 certification elections strongly supported the use of risk-aversion theory to predict employees’ willingness to formally participate in elections. Furthermore, we found that time exhibited a statistically significant, negative relationship with voting participation rates, the percentage of union votes, and union victories. The results also indicated that a saturation effect may exist for delays in the election process. Financial support for this research was provided by the Syracuse University Research Fund. The authors wish to thank two anonymous reviewers for helpful suggestions that significantly improved the paper.  相似文献

Developmental theories depend on characterizing the input to potential learning mechanisms—infants’ everyday experiences. The current study employed a novel ecological momentary assessment (EMA) to measure two aspects of the physical context of those experiences: body position and location. Infant body position was selected because it relates to the development of a variety of other skills. Caregivers of 3‐, 6‐, 9‐, and 12‐month‐olds reported infants’ body position—held, supine, reclined, prone, sitting, or upright—in response to text message notifications over a week to capture infants’ experiences across the entire range of their daily activities. Findings revealed a tremendous disparity in the distribution of body position experiences over the first year. Younger infants spend more time held, supine, and reclined, whereas older infants spend more time sitting and upright. Body position experiences differed substantially between same‐age infants who possess a motor skill (e.g., ability to sit or walk) compared with those who did not, suggesting that developing motor skills change infants’ everyday experiences. Finally, the success of the methodology suggests that similar EMAs might be used to study a wide range of infants’ naturalistic experiences.  相似文献

Variation in densities of native and exotic urban-adapted birds across suburban habitats may reveal levels of adaptation that predict vulnerability to habitat modification over time. We investigated the densities of the eight most common exotic and native birds in a southern hemisphere city across suburbs of varying housing density, vegetative cover and garden vegetation characteristics to determine whether avian population densities are maintained across variations in habitat structure that mirror current temporal trends in land use and landscaping/gardening preferences. We also tested whether densities of birds in residential areas bordering undeveloped patches were higher due to spill-over from patches. Densities of all four native species were highest in undeveloped patches and these species were largely absent from high density housing areas. While densities of two exotic species (blackbird, song thrush) were slightly higher in suburbs with greater vegetation complexity, they were still present in higher density housing suburbs in significant numbers. Common starlings were similarly abundant across all residential habitats and house sparrow density increased in higher density housing areas. Blackbirds appeared least vulnerable to housing densification and landscaping and gardening trends because they were abundant across all habitats, including undeveloped patches. Densities of native birds were higher in residential areas bordering undeveloped patches indicating spill-over was occurring and emphasising the role that patches could play in boosting city-wide native bird abundances. Native birds are vulnerable to reductions in garden size and vegetation complexity that should have little or positive effects on populations of common exotic species.  相似文献

Most theoretical treatments of intimate partner violence (IPV) focus on individual‐level processes. More recently, scholars have begun to examine the role of macrolevel factors. Results of that research indicate that social ties facilitate the diffusion of cultural norms—including tolerance of deviance/violence—across neighborhoods. Yet the influence of the neighborhood normative climate extends beyond norms regarding the use of violence, shaping cultural understanding about dating and the opposite sex. Using data from the Toledo Adolescent Relationships Study (TARS), the current investigation examines the multilevel association between dating norms and IPV perpetration among a large, diverse sample of adolescents and young adults. Results indicate that individuals’ liberal dating attitudes are associated with IPV perpetration. Furthermore, this effect varies across levels of neighborhood disadvantage.  相似文献

The author uses variation by the day of week—comparing weekdays to weekends—to reconsider three main explanations for variation in women's housework time. The author predicts that though evidence of gender deviance neutralization (GDN) should be evident across the days of the week, evidence of time constraints and absolute earnings should be most apparent on weekdays. The author tests these hypotheses with the largest sample to date (American Time Use Survey 2003–2012) and careful consideration of the functional form between resources/constraints and housework time. The author finds that all three measures of resources/constraints—relative earnings, absolute earnings, and employment hours—perform as poor predictors of women's housework on weekends. Weekends are when women, regardless of employment status, do gender, but not in the way hypothesized by GDN. On weekdays, women's own employment hours and earnings have negative, but diminishing, effects on their housework time. GDN is not supported.  相似文献

Although numerous studies have confirmed the separate effects of economic and cultural capital on arts participation, research focusing on the cumulative and interactive effects of economic and cultural capital through the creation of taste publics is limited. Using data from the United States (Survey of Public Participation in the Arts [1982–2012]), this research integrates economic and cultural capital—measured as income and education—into the analysis of taste, creates taste publics, and examines their association with highbrow arts participation over time. We find that the effects of economic and cultural capital on highbrow arts participation decreased between 1982 and 2012, and American publics seem to have converged across both types of capital. Implications of the findings are discussed.  相似文献

This article presents a mixed‐methods, multicase study and comparison of volunteer programs in US national parks that have evolved, in response to growth and fiscal pressures, to be co‐managed by national park staff and their nonprofit support partners. Findings detail why and how the expanded partnerships were formed; how they operate; challenges they face; ways in which they adhere to, stretch, and depart from theories of nonprofit management, collaboration, and program institutionalization; and the significant—even exponential—volunteer program growth that resulted in each case. These nonprofit?public volunteer program partnerships—at Acadia, Arches and ­Canyonlands, Cuyahoga Valley, Golden Gate, the National Mall, and Yosemite national park sites—employ many standard forms of interorganizational relations, even though in these cases the nonprofits give money to the government organization instead of the reverse. Their volunteer program and management structures also share similar elements because of coercive, normative, and mimetic pressures. At the same time, each volunteer program partnership is a distinct blend of collaboration and management practices because of the unique natural features, climate, needs, adjacent populations, and personalities of leaders at each site. The cases employ innovative strategies to substantially increase the number of staff who lead volunteer programs. Recommendations are offered for nonprofit management research and practice, and findings are instructive for organizations that utilize volunteers either as a single entity or as part of a collaboration.  相似文献

Often described as an outcome, inequality is better understood as a social process—a function of how institutions are structured and reproduced, and the ways people act and interact within them across time. Racialized inequality persists because it is enacted moment to moment, context to context—and it can be ended should those who currently perpetuate it commit themselves to playing a different role instead. This essay makes three core contributions. First, it highlights a disturbing parity between the people who are most rhetorically committed to ending racialized inequality and those who are most responsible for its persistence. Next, it explores the origin of this paradox—how it is that ostensibly antiracist intentions are transmuted into “benevolently racist” actions. Finally, it presents an alternative approach to mitigating racialized inequality, one that more effectively challenges the self‐oriented and extractive logics undergirding systemic racism, rather than expropriating blame to others, or else adopting introspective and psychologized approaches to fundamentally social problems, those sincerely committed to antiracism can take concrete steps in the real world—actions that require no legislation or coercion of naysayers, just a willingness to personally make sacrifices for the sake of racial justice.  相似文献

This article investigates the gender differences in participation in voluntary organizations across the life course in Italy. It shows that three forms of engagement in voluntary organizations—donating money, attending meetings, and doing unpaid work—may depend on some stages of the life course—leaving the parental home, forming a union, and becoming a parent—as it is plausible that they may change personal resources and pose constraints or provide opportunities for involvement. Using the household survey “ISTAT Multipurpose Survey—Aspects of daily life”, the article finds that while leaving the parental home is positively associated with both men’s and women’s involvement, forming a union, and being a parent is detrimental for women’s involvement and not for men’s. This pattern indicates that gender roles may constrain more women’s than men’s probability of participation in voluntary organizations.  相似文献

This article examines changes between 1985–1990 and 1995–2000 in relationships between migration and religioethnic identification among U.S. Jews. The results of multivariate analyses of the 1990 and 2000 National Jewish Population Surveys show that Jewish background characteristics have lost their significance as determinants of internal migration and, especially, migration across state boundaries. Concurrently, migration no longer constitutes a serious threat to group continuity and erstwhile negative effects on major religious and social behaviors have disappeared. When the two surveys were integrated into one data set, it was found that “time” enhances the inclination of Jews to move and strengthens their religious and ethnic commitments (though not their commitments to informal Jewish networks). The results are discussed in reference to three competing perspectives of migration‐identification relationships—“selectivity,”“disruption,” and “heightening”—and in the wider theoretical context of religious and ethnic processes in the contemporary United States.  相似文献

This study estimates the prevalence of productive engagement among adults aged 60 and over residing in the United States over a nine-year period. We analyze three waves of data from the Americans' Changing Lives Study, which allows the findings to describe the non-institutionalized older American population. Focusing upon five activities—formal paid employment, irregular paid work, unpaid volunteerism, caregiving, and informal assistance to others—we identify changes in the engagement rates, examine the extent to which engagement occurs through single or multiple concurrent activities, and document intra-individual patterns of engagement within and across forms of productive activity, including the continuity, initiation, and cessation of involvement. The findings reveal that late-life productive engagement is widespread, with the majority of older individuals involved in multiple forms of activity concurrently. Non–market-based activities such as caregiving, informal assistance, and volunteering are most prevalent. Initiation and cessation of activities are common and yield more complex patterns and lower rates of non-participation than are revealed in cross-sectional analyses. Time spent in productive engagement is highly variable and exhibits an overall decline across time. We conclude by highlighting policy strategies to increase the availability and quality of opportunities for productive engagement and promote planning for engagement in late life.  相似文献

Summary

To describe the process that clinicians use to engage vulnerable urban adolescents in mental health counseling, the authors propose a tri-partite model of clinical engagement that takes into account: (1) consumer preference; (2) risk and worry; and (3) youth development (YD) perspectives. These conceptual lenses embody what adolescents want to talk about, their exposure to behavioral and environmental risks, and their coping and strengths. Based on responses given by urban adolescents seeking mental health services to a clinical self-assessment questionnaire (Adquest), this paper uses this tripartite model to summarize patterns of risk that service applicants experience, what they worry about, and how they cope. It explores the substructure of adolescent risk and vulnerability, through factor analysis of relevant items across a broad range of Adquest life areas, to develop a typology of adolescents by risk and worry. Patterns of coping and desire to talk across a range of life areas within this typology are described, as are the practice implications. The authors conclude that even those adolescents who most concern clinicians—because they have high environmental and behavioral risk and low worry-present many different opportunities for engagement.  相似文献

We employ data from the Adolescent Health and Development in Context Study—a representative sample of urban youth ages 11–17 in and around the Columbus, OH area—to investigate the feasibility and validity of smartphone‐based geographically explicit ecological momentary assessment (GEMA). Age, race, household income, familiarity with smartphones, and self‐control were associated with missing global positioning systems (GPS) coverage, whereas school day was associated with discordance between percent of time at home based on GPS‐only versus recall‐aided space‐time budget data. Fatigue from protocol compliance increases missing GPS across the week, which results in more discordance. Although some systematic differences were observed, these findings offer evidence that smartphone‐based GEMA is a viable method for the collection of activity space data on urban youth.  相似文献

Recent scholarship has indicated that political and ethnic threat theories—which maintain that the use of prison is not only determined by the extent of crime in society but also by various features related to power, ideology, and access to resources—provide powerful accounts as to why the use of punishment varies within and between societies. However, no study to date has tested these theories within Canada, a country in which such theories are quite plausible. This study begins to fill this void by assessing these theoretical claims using a pooled time series analysis of the variation in imprisonment rates across Canadian provinces from the years 2001 to 2010. After accounting for several measures including charge rates, the results show that Canadian incarceration rates are largely driven by ethnic threat. The size of the Aboriginal and visible minority populations across each province are the most significant determinants of the variation in punishment. Furthermore, we find a nonlinear relationship consistent with a political version of the threat hypothesis. Results, however, do not support political accounts which stress the power of right‐wing parties or a conservative public.  相似文献

This study is to test a theoretical model regarding the effect of organization—public relationships on organizational reputation. Grounded in multidisciplinary literature, this study proposed that organization—public relational outcomes are hypothesized to influence organizational reputation, considering the exogenous influences of communication behaviors, experience, and familiarity that the research participants hold of the organizations studied. The proposed model illustrated tenable data-model fits, and most of the hypotheses were statistically supported. The key finding of the research includes that, across all organizations studied, organization—public relational outcomes were associated positively with favorable reputation of the organizations studied. Limitations and suggestions for the future research were discussed.  相似文献

The issue of human subject protection in relation to social network research on the spread and control of human pathogens is considered. As this area derives most of its concepts and methods from social network analysis more generally, the present discussion has wider relevance. One problem is that some Institutional Review Boards (IRBs) have assumed that if a participant (who gave informed consent) is to be asked to name network associates these too — automatically — would be human subjects from whom informed consent also must be obtained. Invariably, if this occurs proposed research — whatever its funding and potential contributions might be — is blocked. A conservative approach is taken here. The Common Rule is assumed to provide relevant guidance, the responsibility of IRBs is to make decisions based on the Common Rule, and in consequence the burden is on those proposing social network research to design — and defend — their planned work with this in mind. At the same time, it is argued that it is important not to stifle beneficial research by adding to one inherently conservative review process (of grant proposals) another (of IRBs) so that work is prevented simply because it is research at the frontiers rather than ‘safe’ research.  相似文献

We conduct an extensive review of the literature on testosterone and economic risk‐taking behavior. In sum, there is evidence of a positive association between testosterone and economic risk taking, although it is unlikely to be a strong association given the abundance of null results. However, we argue that the existing literature may overstate the causal effects of testosterone on economic risk taking (or even report a spurious correlation) because this research has not considered the potentially confounding role of social status. Status could concurrently influence both testosterone and economic risk taking, given that testosterone is a social hormone with a reciprocal relationship with social status, and social status has been found to drive risk‐taking behavior. We also argue against using findings from this literature to make gender essentialist claims, primarily because social phenomena influence the size—and existence—of gender differences in economic risk‐taking behavior. We conclude with suggestions for future research.  相似文献
