The literature on employee referral hiring gives little attention to referrers. Synthesizing 2 theories in the literature (the better match and social enrichment accounts), through the lens of social resources theory, I provide a conceptual and empirical breakdown of the effects of referrer quality (referrer performance at hire and referrer tenure at hire) and posthire accessibility (referrer employment and referrer–referral hire job congruence) on referral hire performance and likelihood of voluntary turnover. I tested my hypotheses with longitudinal data from 386 referrer–referral hire pairs at the same job level in a U.S. call center over a 2‐year period. Across analyses of 2 performance criteria (calls/hour and quality) and likelihood of leaving, I found a nuanced mix of benefits and liabilities that illuminate potential boundary conditions of the revised theories. Referral hires from high‐performing referrers performed better but had higher turnover propensities than those from lower performing referrers. Longer‐tenured employees also produced better performing referral hires, up to a point. Referral hires were less likely to leave, provided their referrer remained employed, but they performed less effectively under this condition. Similarly, referral hires performed worse when their job was congruent with their referrer's job. Theoretical and practical implications are discussed.  相似文献

Schizophrenia is characterized by an abnormal dopamine system, and dopamine blockade is the primary mechanism of antipsychotic treatment. Consistent with the known role of dopamine in reward processing, prior research has demonstrated that patients with schizophrenia exhibit impairments in reward-based learning. However, it remains unknown how treatment with antipsychotic medication impacts the behavioral and neural signatures of reinforcement learning in schizophrenia. The goal of this study was to examine whether antipsychotic medication modulates behavioral and neural responses to prediction error coding during reinforcement learning. Patients with schizophrenia completed a reinforcement learning task while undergoing functional magnetic resonance imaging. The task consisted of two separate conditions in which participants accumulated monetary gain or avoided monetary loss. Behavioral results indicated that antipsychotic medication dose was associated with altered behavioral approaches to learning, such that patients taking higher doses of medication showed increased sensitivity to negative reinforcement. Higher doses of antipsychotic medication were also associated with higher learning rates (LRs), suggesting that medication enhanced sensitivity to trial-by-trial feedback. Neuroimaging data demonstrated that antipsychotic dose was related to differences in neural signatures of feedback prediction error during the loss condition. Specifically, patients taking higher doses of medication showed attenuated prediction error responses in the striatum and the medial prefrontal cortex. These findings indicate that antipsychotic medication treatment may influence motivational processes in patients with schizophrenia.  相似文献

To draw valid inference about an indirect effect in a mediation model, there must be no omitted confounders. No omitted confounders means that there are no common causes of hypothesized causal relationships. When the no-omitted-confounder assumption is violated, inference about indirect effects can be severely biased and the results potentially misleading. Despite the increasing attention to address confounder bias in single-level mediation, this topic has received little attention in the growing area of multilevel mediation analysis. A formidable challenge is that the no-omitted-confounder assumption is untestable. To address this challenge, we first analytically examined the biasing effects of potential violations of this critical assumption in a two-level mediation model with random intercepts and slopes, in which all the variables are measured at Level 1. Our analytic results show that omitting a Level 1 confounder can yield misleading results about key quantities of interest, such as Level 1 and Level 2 indirect effects. Second, we proposed a sensitivity analysis technique to assess the extent to which potential violation of the no-omitted-confounder assumption might invalidate or alter the conclusions about the indirect effects observed. We illustrated the methods using an empirical study and provided computer code so that researchers can implement the methods discussed.  相似文献

We have previously shown that repeated retrievals of remote autobiographical memories over the course of one month led to an overall increase in reported detail (Nadel, Campbell, & Ryan, 2007). The current study examined the retrieval of those same memories 1 year later in order to determine whether the level of detail remained stable or whether the memories returned to their original state. Participants reported even more details than they had recalled at least 1 year earlier, including new details that were reported for the first time. This finding was consistent across both multiple and single retrieval conditions, suggesting that the critical factor leading to the increase in recall was the passage of time. These findings provide evidence for long-term effects of repeated retrieval on memory content.  相似文献

The authors reviewed article and author patterns for articles published in the Journal of Employment Counseling (JEC) from 1994 through 2009. Author demographic characteristics assessed included sex of lead and all authors, lead author domicile, employment setting of lead and all authors, and individuals and universities contributing most frequently to JEC. Article content was identified and research articles published in JEC were specifically analyzed for trends over time during 4‐year periods, including type of research design, quantitative/qualitative approach, intervention/nonintervention focus, random versus nonrandom sampling/assignment, sample size, participant types, and statistical analyses used.  相似文献

Conceptual similarities between recent models of insomnia and emotional disorders suggest there may be common factors that underlie or maintain these difficulties. Maladaptive cognitive and behavioral processes similar to those described in connection with emotional disorders have been cited as key mechanisms in the maintenance of primary insomnia. Unfortunately, research on this potential overlap is lacking. The present study examined the relationship among anxiety sensitivity (AS), dysfunctional beliefs, fatigue, safety behaviors, and insomnia severity in 59 outpatients with anxiety and mood disorders. Key insomnia processes (dysfunctional beliefs, fatigue, safety behaviors) were all related to insomnia severity in the comorbid sample, although AS was not. However, as hypothesized, AS did moderate the relationship of both dysfunctional beliefs and fatigue with insomnia severity. The relationships between key insomnia processes and insomnia severity was strongest among individuals high in AS. Results support the hypothesis that common mechanisms are involved for insomnia and emotional disorders. AS might function as a mechanism for the maintenance of sleep disturbance in the context of anxiety and mood disorders, suggesting a promising avenue for future research.  相似文献

Motherhood and sexual appeal are rarely linked in Western culture. There seems to be a notion that once a woman has children she is first and foremost an example, and must be responsible and conservative in a culturally specific way. Most women become mothers at some point in their lives and this is a major physical, emotional, and role transition, one that many women struggle with privately given societal ideals of a ??good?? mother. Despite its essential role in motherhood and life, and the health benefits known to be associated with sexual activity, public expression of sexuality is still primarily associated with being young, childless, and unmarried. Using a social constructionist perspective, we look at the ways in which acceptable expressions of mothers?? sexuality are defined and negotiated by contemporary women. Based on in-depth interviews with fifty women in their 20s, 30s, and 40s, we discuss women??s images of mothers?? sexuality and the ways in which motherhood impacts women??s experiences of sexuality. We find that for most mothers interviewed, the way they felt about sex, their sexual appeal, and their level of sexual desire changed after having children. Coupled with the fatigue and responsibility associated with being a new mother, women felt disconnected from their sexuality for a period of time.  相似文献
