Subordinates' endorsement of an allocating leader in a commons dilemma: An equity theoretical approach

The experiment consisted of two phases. In the free-access phase, subjects in groups of three, harvested from a common, replenishable resource pool. Bogus feedback indicated that the pool was prematurely exhausted. Thereafter, in the proper experimental leader phase, an “elected” bogus leader made resource allocations. The leader's allocation behavior was varied by means of a 3 (Leader-Subordinates Comparison: Leader Over payment, Leader Equal payment, Leader Under payment) ×3 (Intersubordinate Comparison: Subject Over payment, Subject Equal payment, Subject Under payment) factorial design. As predicted, leader endorsement was weakest when the leader overpaid him/herself (Leader-Subordinates Comparison main effect) and when the subject was underpaid in comparison with the fellow subordinate (Intersubordinate Comparison main effect). The interaction effect was ascribed to three circumstances: (1) When the harvests were equally allocated, leader endorsement was strongest; (2) Leader Under payment desensitized the subject to intersubordinate comparison; (3) Subject Over payment desensitized the subject to leader-subordinates comparison.     

The Effects of Contingent Caregiver Imitation of Infant Vocalizations: a Comparison of Multiple Caregivers

The present study replicated and extended the Pelaez et al. (Journal of Applied Behavior Analysis 44:33–40, 2011) study, which examined the reinforcing effects of mothers’ contingent imitation of their infants’ vocalizations. Three infants aged 7–12 months who could vocalize sounds but not words participated with two caregivers for each infant (i.e., triads). During the intervention phase, the caregivers were asked to immediately imitate all vocalizations emitted by the child for a 3-min period. During the yoked control phase, the caregivers listened to an audio recording from the preceding condition and provided vocalizations non-contingently on the infants’ responses. The procedures yielded different results across participants; one infant emitted a higher frequency of vocalizations during the contingent imitation phases over the control phases, and the other two infants showed higher rates of responding during the control phases. However, all infants emitted more imitative return vocalizations during contingent reinforcement conditions compared with the yoked control condition.     

Reinforcement,stereotypy, and rule discovery

The effects of reinforced pretraining on subsequent rule discovery were examined with college students as subjects. Levels of behavioral stereotypy observed during reinforced and non-contingent pretraining were compared. During pretraining subjects received reinforcement if they pressed two keys in a particular sequence. During the problem session pressing each key four times was a necessary condition for reinforcement, but each problem had additional different requirements for reinforcement. Subjects were asked to solve the problems by discovering the rule that determined whether or not they received reinforcement. Levels of stereotyped responding during pretraining were equivalent for contingently and non-contingently trained subjects. During the problem session contingently pretrained, non-contingently pretrained, and naive subjects required equal numbers of trials to solve problems and solved the same number of problems. The results suggest that behavioral stereotypy observed in this experimental preparation may be due to repeated exposure to the task. Differences between the results observed in this study and that of Schwartz (1982) and implications for the use of reinforcement procedures in applied settings are discussed.

     

The effects of specific versus nonspecific reinforcement on verbal behavior

The current study is a systematic replication and extension of previous research on the differences between specific (mand) and nonspecific (tact) reinforcement. The focus was on the role that these different consequences played in the acquisition of verbal behavior. Using both a within-subject and a between-subjects design, the current researchers trained eight essentially nonverbal individuals to tact a variety of foods under two different reinforcement conditions. The results showed no significant differences between the four matched-pairs in rates of acquisition, or in the resistance to extinction. However, subjects in the specific reinforcement condition emitted more untrained mand-compliance responses, while subjects in the nonspecific group demonstrated increased generalization to multiply controlled mand conditions. The results supported previous findings which indicated that the two types of consequences were equally effective in the acquisition of tacting, but each had unique features and implications for language training with nonverbal populations.

     

Stimulus-Stimulus Pairing and Subsequent Mand Acquisition of Children with Various Levels of Verbal Repertoires

Effects of a stimulus-stimulus pairing procedure on the subsequent acquisition of mand operants were investigated. An attempt was made to shape novel sounds that emerged through the pairing procedure into a mand. Six children, aged two to five years, with moderate to severe language and communication delays, participated. Two conditions were used following the pairing condition: postpairing and direct reinforcement. The emergence of mands was compared across these conditions. An additional analysis was made of the relation between participants'' baseline verbal repertoires and the effects of the pairing and the emergence of mands. Results indicate the possibility of stimulus control from a stimulus-stimulus pairing to mand as shown in two of the participants who had demonstrated high rates of vocal play and low to no verbal repertoire prior to this study. Target vocal sounds during postpairing and direct reinforcement condition remained at zero to low levels for participants with high verbal repertoire and little vocal play, warranting future studies on relations between the pre-existing verbal repertoire and the effectiveness of stimulus-stimulus pairing.     

Political geography and interest-group power

The relationship between the distribution of an interest group's members (i.e., voters) across legislative districts and the group's ability to influence government policy is not well understood. We propose a simple model of interest groups and legislative decisionmaking to characterize this relationship formally, and analyze the model for the case of three competing interest groups. We find that an interest group's expected power is maximized when its members are evently divided across (m+1)/2 of the m districts, except when the group is somewhat small, in which case its expected power is maximized when it is evenly divided across all m districts. Expected power decreases sharply as a group's members become concentrated in fewer than (m+1)/2 districts.The author would like to thank the participants of the Workshop in Applications of Economics at the University of chicago fpr their helpful comments, and the Center for the Study of the Economy and the State for its financial support.     

Conflict in Divorcing and Continuously Married Families: A Study of Marital,Parent–Child and Sibling Relationships

ABSTRACT

Family members in both separated or divorcing and married families completed a range of questionnaires about the conflict in 3 relationships—couple, parent–child, and sibling—across 2 phases of the study approximately 12 months apart. In addition, the adolescents completed measures of adjustment: self esteem, depression, and anxiety. Adolescents in a subset of the divorcing families were interviewed about the conflict in their families across the 2 phases (107 at Phase 1 and 35 at Phase 2). Analyses showed that conflict was higher in the separated or divorcing families across all 3 relationships, and that the highest levels of conflict occurred for the high-conflict divorcing families. Qualitative data from interviews illustrated the nature of the conflict that was occurring.     

Emergent Intraverbal Forms may Occur as a Result of Listener Training for Children with Autism

The purpose of the present study was to assess whether intraverbal behavior, in the form of answers to questions, emerges as a result of listener training for five children diagnosed with autism. Listener responses were targeted and taught using prompting and differential reinforcement. Following successful acquisition of listener responses, the intraverbal form of the response was probed. Data were evaluated via a nonconcurrent multiple-baseline design that included a control series. Results showed listener-to-intraverbal transfer for four of the five participants. One participant required additional teaching that involved tacting the items selected during listener training.

     

Two Means Together? Effects of Response Bias and Sensitivity on Communicative Action Detection

Numerous lines of research suggest that communicative dyadic actions elicit preferential processing and more accurate detection compared to similar but individual actions. However, it is unclear whether the presence of the second agent provides additional cues that allow for more accurate discriminability between communicative and individual intentions or whether it lowers the threshold for perceiving third-party encounters as interactive. We performed a series of studies comparing the recognition of communicative actions from single and dyadic displays in healthy individuals. A decreased response threshold for communicative actions was observed for dyadic vs. single-agent animations across all three studies, providing evidence for the dyadic communicative bias. Furthermore, consistent with the facilitated recognition hypothesis, congruent response to a communicative gesture increased the ability to accurately interpret the actions. In line with dual-process theory, we propose that both mechanisms may be perceived as complementary rather than competitive and affect different stages of stimuli processing.

     

Instructional Demonstrations are More Efficient Than Consequences Alone for Children with Naming

Prior research found that without the naming cusp, children did not learn from instructional demonstrations presented before learn units (IDLUs) (i.e., modeling an expected response twice for a learner prior to delivering an instructional antecedent), however, following the establishment of naming, they could. The present study was designed to compare the rate of learning reading and mathematics objectives in children who showed naming using IDLUs compared to standard learn units (SLUs) alone (comparable to three-term contingency trials). In Phase 1, a pre-screening phase, we demonstrated that four typically developing males, 3 to 4 years of age, had naming within their repertoire, meaning they were able to master the names of novel 2-D stimuli as both a listener and a speaker without explicit instruction. Using the same participants in Phase 2, we compared rates of learning under two instructional methods using a series of repeated AB designs where conditions (IDLUs versus SLUs) were counterbalanced across dyads and replicated across participants. The participants learned more than twice as fast under IDLU conditions and showed between 30% and 50% accuracy on the first presentation of a stimulus following a model. The IDLU condition was more efficient (fewer trials to criterion) than the SLU condition. These findings, together with prior findings, suggest that the onset of naming allows children to learn faster when instructional demonstrations are incorporated into lessons.

     

Psychodynamic theory within the politics of social work theory

Abstract

It is argued that social work theory has a politics in which supporters of theoretical perspectives are in discourse. The political position of psychodynamic theory has varied in each of three phases of social work theoretical development: the pre-influence, dominance and alternatives phases. In the dominance phase social work theories usually derived from psychoanalysis, psychodynamic ideas permeated basic social work practices and non-psychodynamic perspectives were influenced by it. In the alternatives phase, these influences continued, psychodynamic theory became a player in a wider discourse, was incorporated into or incorporated other perspectives and continued its dominance in specific settings. However, intensity of criticism of it, non-therapeutic approaches in much of social work, restricted training programmes, poor media of professional communication, the novelty of newer perspectives and poor transfer of new developments in psychodynamic theory have implied an insecure position for psychodynamic theory. But many of these problems are shared by alternative perspectives and its historical strength, strength in related occupations its adaptiveness and inclusiveness and the development of post-qualifying training offer continuing avenues to strengthen its political position within social work theory     

Confidence and the effectiveness of creative methods in qualitative interviews with adults

ABSTRACT

This paper examines two contrasting creative methods; a drawing task and a LEGO building task used in a study exploring the gap between policy and practice in widening participation to higher education across two different types of university in England. These creative methods were used within 16 semi-structured interviews in seven universities to attempt to explore deeper understandings of everyday policy and what they mean in practice and to make comparisons across types of institutions. This paper examines the role that creative confidence played in the effectiveness of both methods through exploring the successes and failures of each arguing that understanding these barriers can improve the successful use of these methods, especially with adults. When these barriers are overcome, the paper also demonstrates how creative methods encouraged more reflective discussion of everyday issues, increased levels of rapport, and shared engagement in the interview process.     

Teaching, research, and service: Expectations of assistant professors

In this article, we critically evaluate the expectations of assistant professors as perceived by junior and senior faculty (n=22) across seven disciplines at two universities. Our research shows that there are similarities and differences within Sociology departments, across disciplines, and across the teaching and research schools where we collected our data. In one respect, Sociology is no different than the other departments where we interviewed faculty members—ambiguity abounds in terms of expectations for junior faculty. Scholarship expectations for tenure and promotion to associate professor vary much more greatly across rank, discipline, and institution than do those for teaching or service. Based on our findings, we offer several suggestions for improving the transition to the role of Assistant Professor in Sociology. Our suggestions focus on change within graduate programs, hiring institutions, and Sociology as a discipline. While our results are consistent with prior research in many cases, we note that the generalizability of our findings is limited given the number of interviews conducted and the purposive sampling design utilized. However, we hope that our results will provide additional information that may help others as they prepare to begin their roles as assistant professors.     

The Microlevel Discourse of Social Movement Framing: Debating Antiwar Protests on a University Listserv

Abstract

Over the past two decades, researchers have increasingly employed frame analysis in attempts to understand the genesis, development, and outcomes of social movements. Relatively little attention, however, has focused on the microlevel processes involved in generating social movement frames. This paper is an effort to link theories of social movement framing with the methodology of discourse analysis. In the following, an online debate over the legitimacy of protests against the 2003 invasion of Iraq by the United States provides qualitative data for a discourse analysis of microlevel framing processes. The debate occurred on a university listserv and involved more than 100 messages offered by 67 individuals over 16 days. Analyses reveal four distinct framing contests in the discourse. An initiating contest regarding a specific antiwar protest is found to generate three additional contests, the first about antiwar protests more generally, the second about the war in Iraq itself, and the third about the appropriateness of holding such a debate on a listserv sent to university employees. A framing process schema is offered to represent conflict between social movement and countermovement participants across the discourse.     

Common urban birds continue to perceive predator calls that are overlapped by road noise

Recent studies suggest that songbird communication is negatively affected by anthropogenic noise. However, much of the current literature focuses on inter- and intra-sexual communication. Songbirds also use acoustic cues for many other functional behaviors. One example associated with fitness consequences is the identification of predatory threats through acoustic cues. To test the effect of anthropogenic noise on detection of acoustic cues, we compared the rates of seven anti-predator behavioral responses in urban dwelling songbirds foraging at bird feeders when exposed to playback of calls from predatory Cooper’s hawks under quiet conditions, and when overlapped with road noise. Only a single behavior, freeze response, decreased significantly when calls were overlapped with noise. However, freeze responses occurred in only a small percentage of playback trials, raising some question regarding the biological relevance of this observed difference. Overall, our results suggest that common urban songbirds are relatively successful at perceiving acoustic signals associated with predator presence. Whether this ability is commonplace amongst songbird species is unknown and warrants additional study. However, if this trait is not widespread, it may be an additional characteristic determining which bird species can inhabit noisy areas.

     

How parents suspected of child maltreatment change their cognition and behavior: A process model of outreach and child protection,generated via grounded theory

AimAlthough considerable efforts have been made to improve relationships between professionals and parents suspected of child maltreatment, little research has been conducted to examine the ways in which parents escalate their negative cognition and behavior involving professionals. This study developed a model of parents' negative reinforcement of their cognitive behavior and the factors influencing reductions in this reinforcement.MethodInterview data were collected from 21 parents, who had experienced outreach and child protection issues, and analyzed using the grounded theory approach.ResultIn the outreach phase, the analysis initially produced the negative image of help-seeking behavior category, followed by the dissatisfaction with outreach and reinforcement of negative cognition categories. In this phase, the analysis also identified the social support and support groups step as a means of reducing negative cognition. In contrast, in the child protection phase, the analysis produced the anger and psychological conflict with child protection services and unwilling consent categories. In this phase, the analysis also identified the psychoeducation and timely feedback step as an acceptable means of minimizing the escalation of negative cognition.ConclusionThe hypothetical model revealed the ways in which parents changed their cognition and behavior and demonstrated the factors influencing reductions in the reinforcement of negative cognition and behavior. These results could be useful for practice in child maltreatment cases.     

Clean and green organizing in urban neighborhoods: Measuring perceived and objective outcomes

ABSTRACT

One way in which urban community organizations attempt to improve neighborhood health is through cleaning and greening efforts. Few studies have evaluated how such efforts are related to changes in both residents’ perceptions of neighborhoods and objective community-wide cleaning and greening indicators over time. Drawing upon quantitative and qualitative data collected during an evaluation of a community-building initiative in two communities, results show how neighborhood changes in cleaning and greening were reflected in perceived and objective measures and how these measures compare across different time periods and sub-groups of residents within the two target communities. We provide suggestions for additional ways that future evaluations of urban cleaning and greening efforts can examine the impact.     

Comparative Analysis of State Statutes

Abstract

The purposes of this study were to analyze statutory requirements regarding prenatal substance abuse reporting, related healthcare assessments, and state interventions with reported women and their families. The author conducted a legal search of the statutes of ten states, which were identified as having “specific gestational abuse statutes” in previous literature (Lieb & Sterk-Elifson, 1995).

The findings revealed that seven of the ten states included a specific reporting requirement. Even in these seven states, neither assessment procedures nor treatment provisions were well-delineated. Only three states had specific provisions on therapeutic intervention with reported women. Based on the findings, three principles for a model statute are recommended for balancing the rights of infants and mothers.
