Is the Source of Reinforcement for Naming Multiple Conditioned Reinforcers for Observing Responses?

Naming refers to the incidental acquisition of word-object relations as listener and speaker without explicit reinforcement. To investigate possible sources of reinforcement for naming, we examined the effects of a procedure for conditioning reinforcement for observing responses on the emergence of naming in children who previously lacked it. The participants were three 5- to 7-year-old children with and without diagnoses of autism spectrum disorder. During the intervention, either visual or auditory stimuli were first conditioned as reinforcers for observing responses. Then, neutral visual or auditory stimuli were paired with the conditioned visual or auditory stimuli until both visual and auditory stimuli acquired reinforcing properties for observing. Following this intervention, the participants demonstrated naming of stimuli that had been used in pretests for naming, as well as on a novel set of stimuli. We observed increases in echoic responding in conjunction with the emergence of naming and conditioned reinforcement for both observing responses. We interpret the data as suggesting that listener and speaker repertoires are joined for naming only when both visual and auditory stimuli reinforce the observing responses of looking and listening simultaneously.     

Protest Suicide: A Systematic Model with Heuristic Archetypes

Suicide as a form of political protest is a little studied social phenomenon that cannot be dismissed simply as being irrational or patholognomic. We consider protest suicide to be a meaningful social action as purposive political act intended to change oppressive policies or practices. This paper synthesizes theoretical propositions associated with suicide in general, and protest suicide in particular, so as to construct a general explanatory model of protest suicide as a social phenomenon. Then, it analyzes protest suicide as a meaningful social action. People considering protest suicide have to discern the logic of the situation in which such action is to take place. This involves answering two fundamental questions: Is suicide an acceptable course of social action? Is the envisaged protest suicide likely to achieve their hopes, aspirations and goals? How these questions are answered gives rise to a set of protest suicide archetypes. Our analysis generates a more sophisticated understanding of the potential reasons for, and motivations behind, protest suicide as a social phenomenon.     

Unraveling the effect of offender citizenship status on federal sentencing outcomes

A large body of social science literature has focused on the factors that influence sentencing outcomes within the federal court system. A neglected variable in this line of research is the citizenship status of the offender. Using the United States Sentencing Commission’s Monitoring of Federal Criminal Sentences data from 2006, the present study examines the effect of citizenship status on the likelihood of incarceration and the length of the prison sentence. This study extends previous research in three ways: first, by examining citizenship status using post-Booker data; second, exploring the differences between citizens, legal aliens, and illegal aliens rather than comparing all non-citizens to US citizens; and third, examining all offenses rather than only drug offenses. Most importantly, this study partitions the data by citizenship status to determine if the effects of race/ethnicity and other variables (e.g., type of offense and level of education) vary by citizenship status. The results demonstrate that both legal and illegal aliens have a higher probability of incarceration than similarly-situated US citizens, but that the sentences imposed on illegal aliens are shorter than those imposed on citizens. However, different results emerged when the data were partitioned by citizenship status. Judges imposed shorter prison sentences on Latino citizens, but longer prison sentences on Latino illegal aliens. These results are discussed in relation to theoretical explanations and policy implications.     

Psychological Contracts and Organizational Identification: The Mediating Effect of Perceived Organizational Support

Understanding the processes through which employees incorporate the organization’s identity into their own identity is critical to building positive employer-employee relationships. We draw primarily on organizational support theory to advance the argument that psychological contract breach is negatively related to organizational identification and positively related to organizational disidentification because it makes employees believe that their organizations do not value their contributions or care about their well-being (reduces perceived organizational support). Results from two studies generally provide support for our hypotheses: in Study 1, perceived organizational support fully mediated the relationship between psychological contract breach and organizational identification. In Study 2, Time 2 perceived organizational support fully mediated the relationship between Time 1 relational psychological contract breach (e.g., promises related to training, development, job security) and organizational identification, but not the relationship between transactional psychological contract breach (e.g., promises related to pay and work hours) and organizational identification. Time 2 perceived organizational support partially mediated the relationship between relational psychological contract breach and organizational disidentification, but not the relationship between transactional psychological contract breach and organizational disidentification. We conclude that organizations should be concerned with this erosion of the positive employer-employee relationship (organizational identification) and fostering of a negative employer-employee relationship (disidentification).     

On Determining the Dimension of Real-Time Stock-Price Data

We estimate the dimension of high-frequency stock-price data using the correlation integral of Grassberger and Procaccia. The data, even after filtering, appear to be of low dimension. To control for dependence in higher moments, we use a new technique known as the method of delays in our reconstruction. Delaying the data leads dimension estimates similar to random processes. We conclude that the data are either of low dimension with high entropy or nonlinear but of high dimension.     

Economic Hardship and Family-to-Work Conflict: The Importance of Gender and Work Conditions

Using data from a 2007 national survey of working Americans, we examine the association between economic hardship and family-to-work conflict (FWC). We also assess contingencies of this association, focusing particularly on gender and several work conditions. Findings indicate that economic hardship is associated with higher FWC; this pattern is stronger among men. Three work conditions also function as effect modifiers: The positive association between hardship and FWC is stronger for workers with less job authority and more creative work activities. Job pressures also modify this association, but overall, respondents with higher pressures report greater FWC. We discuss how our observations contribute to knowledge about the links between economic conditions and the family–work interface and the importance of status and work-related contingencies.     

TOO MANY MEN? SEX RATIOS AND WOMEN'S PARTNERING BEHAVIOR IN CHINA

The relative numbers of women and men are changing dramatically in China, but the consequences of these imbalanced sex ratios have received little attention. We merge data from the Chinese Health and Family Life Survey with community-level data from Chinese censuses to examine the relationship between cohort- and community-specific sex ratios and women's partnering behavior. Consistent with demographic-opportunity theory and sociocultural theory, we find that high sex ratios (indicating more men relative to women) are associated with an increased likelihood that women marry before age 25. However, high sex ratios are also associated with an increased likelihood that women engage in premarital and extramarital sexual relationships and have had more than one sexual partner, findings consistent with demographic-opportunity theory but inconsistent with sociocultural theory.     

Boundary-spanning work demands and their consequences for guilt and psychological distress

Using data from a national survey of working Americans (Work, Stress, and Health Survey; N = 1,042), the authors examine the associations between boundary-spanning work demands and self-reported feelings of guilt and distress. The authors document gender differences in the emotional and mental health consequences of boundary-spanning work demands, as indexed by the frequency of receiving work-related contact outside of normal work hours. Specifically, the authors observe that frequent work contact is associated with more feelings of guilt and distress among women only. Analyses also demonstrate that guilt accounts for the positive association between the frequency of work contact and distress among women. Statistical adjustments for levels of guilt reduce the positive association between frequent work contact and distress among women to nonsignificance. The findings underscore the importance of focusing on gender and emotions in work-family interface processes, as well as their implications for psychological health.     

Individual versus family psychotherapy in managed care: comparing the costs of treatment by the mental health professions

In an effort to understand how psychotherapy is practiced in the "real world," outpatient claims data were examined to determine the cost of individual and family therapy provided by marital and family therapists, master's nurses, master's social workers, medical doctors, psychologists, or professional counselors. Claims for 490,000 unique persons over 4 years were obtained from CIGNA. Family therapy proved to be substantially more cost-effective than individual or "mixed" psychotherapy. Physicians provided care in the fewest sessions, marital and family therapists had the highest success (86.6%) and lowest recidivism rates (13.4%), and professional counselors were the least costly. Outcomes were overwhelmingly successful, with 85% of patients requiring only one episode of care.
