Rats were given a choice in a two-compartment box between response-dependent and response-independent schedules of food presentation. In general, the response-independent schedule was preferred, but the preference was not exclusive and considerable amounts of time were spent on the “work” (response-dependent) side. Food deprivation caused an increased preference for the response-independent schedule when the schedules were fixed, but not when they were variable. Addition of a signal to the work side, indicating the availability of reinforcement, increased preference for that side. In general, the relative numbers of reinforcements obtained on the response-independent side exceeded the relative time spent there; when the relative reinforcements were equated by adding delays to the response-independent side, indifference between the schedules resulted. Latencies of food collection were higher on the response-independent side than on the lever side, and it is suggested that this gives a clue to the factors maintaining “work” in this situation. 相似文献

Numerous studies have shown the positive consequences of work engagement for both organisations and employees experiencing it. For instance, research has demonstrated that work‐engaged employees have lower levels of turnover intentions than non‐engaged employees. However, in this research, we examined whether there is a dark side of work engagement. More precisely, we investigated whether the relationship between work engagement and employees' turnover intentions might be non‐linear. Based on two different samples, our results indicated that the relationship between work engagement and employees' turnover intentions is curvilinear. The theoretical and practical implications of these results are discussed. 相似文献

This study investigated the variables that shaped people's willingness to engage in collective action in the context of the Occupy Movement. Data were collected in 2011 from nonprotesting supporters at the New York City Occupy encampment and active occupiers at the New York and Atlanta encampments. Participants distinguished between different kinds of collective action based on cost. Furthermore, different predictors motivated distinct kinds of collective action. Identity and anger predicted low‐cost collective action. Efficacy predicted relatively costly collective action and mediated the link between identity and costly collective action. This study provides evidence that people draw distinctions between different actions based on cost and that, when it comes to predicting collective action, these distinctions matter. 相似文献

Incentives are a popular method to achieve desired employee performance; however, research on optimal incentive magnitude is lacking. Behavioral economic demand curves model persistence of responding in the face of increasing cost and may be suitable to examine the reinforcing value of incentives on work performance. The present use‐inspired basic study integrated an experiential human operant task within a crowdsourcing platform to evaluate the applicability of behavioral economics for quantifying changes in workforce attrition. Participants included 88 Amazon Mechanical Turk Workers who earned either a $0.05 or $0.10 incentive for completing a progressively increasing response requirement. Analyses revealed statistically significant differences in breakpoint between the two groups. Additionally, a novel translation of the Kaplan‐Meier survival‐curve analyses for use within a demand curve framework allowed for examination of elasticity of workforce attrition. Results indicate greater inelastic attrition in the $0.05 group. We discuss the benefits of a behavioral economic approach to modeling employee behavior, how the metrics obtained from the elasticity of workforce attrition analyses (e.g., P max) may be used to set goals for employee behavior while balancing organizational costs, and how economy type may have influenced observed outcomes. 相似文献

As understanding of the impact of trauma on children has grown, there has been increasing interest in the use of screening the medical setting to identify which children at risk may be symptomatic. This study was undertaken to determine whether the use of a trauma assessment tool to screen for trauma symptoms in the setting of a foster care clinic was feasible and more sensitive than non-standardized approaches in the context of outpatient primary care. Using a chart review of trauma symptom identification before and after the implementation of the Trauma Symptom Checklist for Children (TSC-C) and the Trauma Symptom Checklist for Young Children (TSC-YC), validated trauma assessment tools, we looked at the feasibility of use of this tool and likelihood of trauma symptom identification. 73 % (n = 204) of eligible patients had a trauma screening tool in the medical record following the introduction of the use of the TSC. Detection of trauma symptoms was higher in the screening period than in the baseline period for the entire population (78 vs. 46 %, p < 0.0001), and trauma symptoms were identified with more specificity following the introduction of, and likely due to, formal trauma screening. However, there were limitations as to feasibility in the outpatient medical clinic. In conclusion, the use of the TSC-C and TSC-YC in the setting of an outpatient foster care evaluation clinic increased rates and precision of identification of trauma symptoms, but had limitations to its feasibility of use in the outpatient clinic setting. 相似文献

Numerous studies have shown that perceived organizational support has positive consequences on both employees and organizations. However, no study has examined the causal relationship between perceived organizational support and proactive behaviour directed towards the organization and few studies have identified potential mechanisms underlying this relationship. We first investigated the direction of causality between perceived organizational support and proactive behaviour, and hypothesized that perceived organizational support leads to proactive behaviour directed towards the organization. Second, based on social exchange and motivational perspectives, we examined two potential mechanisms underlying this relationship, i.e., felt obligation and work engagement. Employees from a Belgian Federal Public Service were invited to take part in a three-wave longitudinal survey. Using a cross-lagged panel design, our results (N = 1963) revealed that Time 2 perceived organizational support was positively related to Time 3 proactive behaviour towards the organization, whereas the reverse was not true. Additionally, our results (N = 1293) showed that Time 2 felt obligation and Time 2 work engagement mediated the positive relationship between Time 1 perceived organizational support and Time 3 proactive behaviour directed towards the organization. 相似文献

This paper examines the acculturation process of male Central American-origin youths in Toronto, a group who are known to have a higher than average risk of dropping out of high school. Using data from semi-structured interviews with a small sample of male youths born in the region or born in Canada to parents from the region, we examine interrelated and shifting friendship patterns, ethno-social identities, and aspirations for schooling. The findings reveal that some youths become marginalized with weak friendship networks, diffuse ethno-social identities and low school completion aspirations, while others develop relatively strong affiliations exclusively with co-ethnic friends who have modest school completion goals. The strongest trend was toward being integrated with a mix of co-ethnic friends and those from other backgrounds, hybrid ethno-social identities, and higher schooling goals. The analysis examines whether the youths are aware of the relationships between social belonging and academic belonging, and whether they feel it possible to escape from being “boxed in” to acculturation patterns associated with poor school completion. These findings add to research on efforts to understand and improve schooling outcomes for “at risk” minority youth in a multicultural city. 相似文献

The cultivation effect is well established: The more media we consume, the more our worldviews come to reflect the mediated world. Several advancements have been made in the past decade exploring the processes underlying the effect. Importantly, the judgments are often heuristically based (Shrum, 2001, 2009), with relevance of the media information an important moderator of this process. Mental construal level, in which people are considered to be thinking on a relatively concrete (psychologically close, specific) level or a relatively abstract (psychologically distant, general) level, may influence these cognitive processes. The present studies find that mental construal level (concrete or abstract) moderates the classic cultivation effect for first-order judgments. Specifically, concrete construal encourages the cultivation effect with a stronger relationship between media consumption and violence prevalence estimates, but abstract construal reduces the effect. Comparison to a control condition in Experiment 2 indicates that concrete construal may be the default state for cultivation effects. One possible explanation for the effect of construal on cultivation effects is that construal influences relevance of and reliance on media cues in judgment formation. 相似文献

Infidelity has a permeating impact on social systems, but no system is more impacted by infidelity than the nuclear family. This paper examines the impact of parental infidelity on the family using a structural family therapy (SFT) framework. Conceptualizing and treating infidelity from an SFT approach provides a systemic understanding of how interactions between the parental units about infidelity impact parent–child dynamics. Clinical recommendations are outlined for couple and family therapists to help families find healthy and adaptable ways to create and maintain structures that minimize the harmful impact of infidelity on the family system. 相似文献
