Learning Skinner’s Verbal Operants: Comparing an Online Stimulus Equivalence Procedure to an Assigned Reading

The purpose of the present study was to compare the effects of an online stimulus equivalence procedure to that of an assigned reading when learning Skinner’s taxonomy of verbal behavior. Twenty-six graduate students participated via an online learning management system. One group was exposed to an online stimulus equivalence procedure (equivalence group) that was designed to teach relations among the names, antecedents, consequences, and examples of each elementary verbal operant. A comparison group (reading group) read a chapter from a popular textbook. Tests for the emergence of selection-based and topography-based intraverbal responses were then conducted, as were tests for generalization and maintenance. Overall, results suggest that the online equivalence procedure was not significantly more effective in promoting topography-based responses than the assigned reading. However, performance on selection-based tests was enhanced by the online equivalence procedure as was performance on topography-based tests when participants were required to provide operant names in response to consequences or examples. On average, the equivalence group performed at a level that was 10 percentage points (i.e., a full letter grade) above that of the reading group. The viability of the equivalence-based procedure is discussed in relation to the assigned reading.     

#Funeral and Instagram: death,social media,and platform vernacular

This paper presents findings from a study of Instagram use and funerary practices that analysed photographs shared on public profiles tagged with ‘#funeral’. We found that the majority of images uploaded with the hashtag #funeral often communicated a person's emotional circumstances and affective context, and allowed them to reposition their funeral experience amongst wider networks of acquaintances, friends, and family. We argue that photo-sharing through Instagram echoes broader shifts in commemorative and memorialization practices, moving away from formal and institutionalized rituals to informal and personalized, vernacular practices. Finally, we consider how Instagram's ‘platform vernacular’ unfolds in relation to traditions and contexts of death, mourning, and memorialization. This research contributes to a broader understanding of how platform vernaculars are shaped through the logics of architecture and use. This research also directly contributes to the understanding of death and digital media by examining how social media is being mobilized in relation to death, the differences that different media platforms make, and the ways social media are increasingly entwined with the places, events, and rituals of mourning.     

An Alternative FMEA Method for Simple and Accurate Ranking of Failure Modes

Failure modes and effects analysis (FMEA) is a methodology for prioritizing actions to mitigate the effects of failures in products and processes. Although originally used by product designers, FMEA is currently more widely used in industry in Six Sigma quality improvement efforts. Two prominent criticisms of the traditional application of FMEA are that the risk priority number (RPN) used to rank failure modes is an invalid measure according to measurement theory, and that the RPN does not weight the three decision criteria used in FMEA. Various methods have been proposed to mitigate these concerns, including many using fuzzy logic. We develop a new ranking method in this article using a data‐elicitation technique. Furthermore, we develop an efficient means of eliciting data to reduce the effort associated with the new method. Subsequently, we conduct an experimental study to evaluate that proposed method against the traditional method using RPN and against an approach using fuzzy logic.     

Increasing aging and advocacy competency: the intergenerational advocacy pilot project

The Council on Social Work Education's (CSWE) Strengthening Aging and Gerontology Education for Social Work (SAGE-SW) project, funded by the John A. Hartford Foundation partnered with the National Committee to Preserve Social Security and Medicare (NCPSSM) to develop an Intergenerational Policy and Advocacy Project (IAP). This curriculum pilot project, based on a community organization model, was conducted with 13 baccalaureate social work (BSW) and master's social work (MSW) programs across the country and 122 students. The project was one method to pursue CSWE SAGE-SW's efforts to infuse aging content into social work foundation curricula, to support intergenerational teaching, to strengthen social work advocacy skills, and to provide social work students with positive experiences working with older adults. Pilot sites were asked to carry out the project as part of an existing course foundation or field practicum course. Project activities included collaboration with a variety of community agencies, holding issues or "town hall" forums in order to educate community members about critical policy issues affecting older adults; making contacts and establishing relationships with local, state and/or federal legislators; and conducting assessments of the service needs of older adults in the students' communities. Questionnaires, feedback, pre-post evaluations as well as brief accounts of each project are presented. Participants considered the IAP to be a successful project in terms of the objectives of increasing awareness and competency among social work students of aging issues and of promoting intergenerational linkages between older people and social work students.     

Assessing capacity in the setting of self-neglect: development of a novel screening tool for decision-making capacity

Compared with older adults with disabilities and those who autonomously choose to live in squalor, self-neglect syndrome arises from a predicate state of vulnerability in frail older adults. This state of vulnerability is characteristically associated with a decline in decision-making capacity regarding the ability to care for and protect oneself. We developed the COMP Screen to evaluate vulnerable older adults to identify potential gaps in decision-making capacity using a screening tool. A total of 182 older adults were evaluated and consistent declines in cognitive ability and decision-making processes were present in this population. However, there were no significant differences between elders referred for self-neglect and matched older adults. These findings suggest that declines in decision-making processes are not uncommon in vulnerable older adults but traditional conceptualizations of decision-making capacity may be inadequate for differentiating the capacity for self-care and protection in elders who self-neglect.     

Nonparametric Identification and Estimation of Nonadditive Hedonic Models

This paper studies the identification and estimation of preferences and technologies in equilibrium hedonic models. In it, we identify nonparametric structural relationships with nonadditive heterogeneity. We determine what features of hedonic models can be identified from equilibrium observations in a single market under weak assumptions about the available information. We then consider use of additional information about structural functions and heterogeneity distributions. Separability conditions facilitate identification of consumer marginal utility and firm marginal product functions. We also consider how identification is facilitated using multimarket data.     

The role of leadership in shared mental model convergence and team performance improvement: An agent-based computational model

Research in shared mental models has immeasurably aided our understanding of effective teamwork and taskwork. However, little research has focused on the role that leaders play, if any, in influencing, developing and/or fostering shared mental models and thereby improving team performance. We developed an agent-based computational model based on McComb's theory of three-phase mental model development, where agents repeatedly share individual opinions (orientation phase), evaluate and respond to the opinions expressed by others (differentiation phase), and modify their understanding of the team based on the responses (integration phase). Leadership and team properties are represented in three experimental parameters: social network structure, heterogeneity of agents' domains of expertise, and level of their mutual interest. Participative leadership is represented by a fully connected network, while Leader–Member eXchange (LMX) is represented by a fully connected network of in-group members and several out-group members connected only to the leader. Our simulation results show that, in general, participative leadership promotes mental model convergence better than LMX. In the meantime, the team performance improvement is achieved by participative leadership only when members have both heterogeneous domains of expertise and strong mutual interest. In all other conditions, participative leadership causes the worst degradation of team performance through team development processes, while LMX is the best to minimize such team degradation. Implications and suggestions for future research are provided.     

Screening and brief intervention for alcohol problems in a university student health clinic

The purposes of this study were (1) to determine whether a university student health center (SHC) is a feasible location to introduce a campus-based screening and brief intervention (SBI) program for alcohol and (2) to determine whether the patients seen in the SHC differ in terms of the prevalence and severity of alcohol-related problems compared with students reported by emergency department programs. The authors used motivational interview techniques to counsel subjects from a convenience sample of patients waiting for medical treatment in the SHC who had screened positive with the Alcohol Use Disorders Identification Test (AUDIT). The authors interviewed patients again after 3 months. Seventy-five percent of eligible students participated. Sixty percent screened positive and received an intervention. The authors contacted 66 students (51.2%) again after 3 months. Seventy-five percent of students interviewed again after 3 months reported that SBI was helpful, 92% found the information clear, and 90% thought that the SHC was a good place to learn this information.     

Mistrusting companies, mistrusting the tobacco industry: clarifying the context of tobacco prevention efforts that focus on the tobacco industry

Campaigns to prevent adolescent smoking increasingly depict the tobacco industry as deceitful and exploitative. This study was undertaken to determine how adolescents' expectations about the trustworthiness of companies, in general, influence the pathway through which anti-tobacco industry campaigns prevent smoking. Structural equation modeling was used with survey data from 6,670 adolescents, ages 12 to 17. In the first model, statistically significant coefficients were associated with paths from mistrust of companies to mistrust of the tobacco industry, from mistrust of the tobacco industry to anti-tobacco industry attitudes, and from anti-tobacco industry attitudes to smoking. In models stratified by mistrust of companies, paths from mistrust of the tobacco industry to anti-tobacco industry attitudes and from anti-tobacco industry attitudes to smoking appeared comparable among youth with both high and low mistrust of companies. These results suggest that anti-tobacco industry campaigns resonate with youth because of youths' trust-related values and expectations.     

First Things First: a framework for successful secondary school reform

If youth development initiatives are going to focus on outcomes that we know are important in settings that we know can change these outcomes, the first outcomes should be educational, and the first setting should be school. School reform presents the most feasible, defensible, and informed opportunity for public policy to improve the life chances of children and youth in disadvantaged communities. This chapter introduces First Things First (FTF), a school reform framework grounded in research about how young people develop and how schools promote students' engagement and learning. The chapter explores four critical features of FTF that focus on students: (1) continuity of care; (2) increased instructional time; (3) high, clear, and fair standards; and (4) enriched opportunities for students. The critical features of FTF are implemented through three strategies: small learning communities, a family advocate system, and instructional improvement.
