Ethics in an operations management course

Graduates of the management major at the University of Pittsburgh at Greensburg find employment in a variety of organizations. As future managers with employees from different professions, students expressed an interest in discussing ethics cases in the operations management class. The semester starts with students familiarizing themselves with various professional and corporate codes of ethics. Throughout the semester a number of short ethics’ cases in operations’ areas such as inventory management, scheduling, facility location, and product design are introduced to illustrate ethical issues that a manager and his/her employees might face. Students prepare individual responses before the in-class discussions. The semester ends with a long group ethics case discussion and formal case presentations. In the end-of-semester survey, students responded very favorably to an ethics component in the operations management class. An earlier version of this paper was presented at the Fourteenth Annual Meeting, Association for Practical and Professional Ethics, February 24–27, 2005.     

The Soldier Fitness Tracker: global delivery of Comprehensive Soldier Fitness

Carefully implemented technology strategies are vital to the success of large-scale initiatives such as the U.S. Army's Comprehensive Soldier Fitness (CSF) program. Achieving the U.S. Army's vision for CSF required a robust information technology platform that was scaled to millions of users and that leveraged the Internet to enable global reach. The platform needed to be agile, provide powerful real-time reporting, and have the capacity to quickly transform to meet emerging requirements. Existing organizational applications, such as "Single Sign-On," and authoritative data sources were exploited to the maximum extent possible. Development of the "Soldier Fitness Tracker" is the most recent, and possibly the best, demonstration of the potential benefits possible when existing organizational capabilities are married to new, innovative applications. Combining the capabilities of the extant applications with the newly developed applications expedited development, eliminated redundant data collection, resulted in the exceeding of program objectives, and produced a comfortable experience for the end user, all in less than six months. This is a model for future technology integration.     

Contingency management in an introductory psychology course produces better learning

For the contingency management techniques first devised by Keller (1966, 1968) to become a widely accepted teaching method, it is necessary that they be shown (1) to be applicable to general subject matter and (2) to be superior to traditional lecture methods. The present study demonstrated (1) by successfully teaching the material from a standard psychology text. The superiority of contingency management was established by direct comparison of final examination scores from comparable groups taught the same subject matter by either Keller's method or traditional methods. Students taught by Keller's method also rated the course more favorably.

Finally, the article provides examples of the performance management projects students have conducted with local businesses.     

Comprehensive stereotype content dictionaries using a semi‐automated method

Advances in natural language processing provide accessible approaches to analyze psychological open‐ended data. However, comprehensive instruments for text analysis of stereotype content are missing. We developed stereotype content dictionaries using a semi‐automated method based on WordNet and word embeddings. These stereotype content dictionaries covered over 80% of open‐ended stereotypes about salient American social groups, compared to 20% coverage from words extracted directly from the stereotype content literature. The dictionaries showed high levels of internal consistency and validity, predicting stereotype scale ratings and human judgments of online text. We developed the R package Semi‐Automated Dictionary Creation for Analyzing Text (SADCAT; https://github.com/gandalfnicolas/SADCAT ) for access to the stereotype content dictionaries and the creation of novel dictionaries for constructs of interest. Potential applications of the dictionaries range from advancing person perception theories through laboratory studies and analysis of online data to identifying social biases in artificial intelligence, social media, and other ubiquitous text sources.     

Evidence for serial coercion: a time course analysis using the visual-world paradigm

Metonymic verbs like start or enjoy often occur with artifact-denoting complements (e.g., The artist started the picture) although semantically they require event-denoting complements (e.g., The artist started painting the picture). In case of artifact-denoting objects, the complement is assumed to be type shifted (or coerced) into an event to conform to the verb's semantic restrictions. Psycholinguistic research has provided evidence for this kind of enriched composition: readers experience processing difficulty when faced with metonymic constructions compared to non-metonymic controls. However, slower reading times for metonymic constructions could also be due to competition between multiple interpretations that are being entertained in parallel whenever a metonymic verb is encountered. Using the visual-world paradigm, we devised an experiment which enabled us to determine the time course of metonymic interpretation in relation to non-metonymic controls. The experiment provided evidence in favor of a non-competitive, serial coercion process.     

The time course of argument reactivation revealed: using the visual world paradigm

Previous research has found that the single argument of unaccusative verbs (such as fall) is reactivated during sentence processing, but the argument of agentive verbs (such as jump) is not (Bever & Sanz, 1997; Friedmann, Taranto, Shapiro, & Swinney, 2008). An open question so far was whether this difference in processing is caused by a difference in thematic roles the verbs assign, or a difference in the underlying syntactic structure. In the present study we tease apart these two potential sources. In order to achieve this, we included a set of verbs (like sparkle) which are equal to unaccusative verbs in the thematic role they assign to their argument, but equal to agentive verbs in the syntactic status of their argument (henceforth mixed verbs). As a method we used the visual world paradigm as this enables us to measure processing of the sentences continuously. This method also allowed us to test another hypothesis, namely the hypothesis that not only the argument of unaccusative verbs is reactivated during processing, but also the argument of agentive verbs. This reactivation is expected as the result of integrating the verb and its argument into one representation. In our experiment, participants listened to sentences including one of the three types of verbs. While listening, they viewed a visual display in which one of four objects was strongly related to the argument of the verb (wood-saw). The gaze record showed that the eyes moved to the related object (saw) upon presentation of the argument (wood). More interestingly, the eyes moved back to the related object upon presentation of the verb (fell). We found that looks to the related object increase only late after verb offset for unaccusative verbs, replicating the findings of previous research. We also found a rise in looks to the related object in agentive verbs, but this rise took place much earlier, starting slightly after verb onset. Finally, we found that mixed verbs pattern in processing with agentive verbs. We conclude that the argument of the verb is always reactivated, independent of verb type. In addition, the timing of integration differs per verb type and depends on the syntactic status of the argument and not on the thematic role that is assigned to the argument.     

Investigating the time course of tactile reflexive attention using a non-spatial discrimination task

Peripheral cues are thought to facilitate responses to stimuli presented at the same location because they lead to exogenous attention shifts. Facilitation has been observed in numerous studies of visual and auditory attention, but there have been only four demonstrations of tactile facilitation, all in studies with potential confounds. Three studies used a spatial (finger versus thumb) discrimination task, where the cue could have provided a spatial framework that might have assisted the discrimination of subsequent targets presented on the same side as the cue. The final study circumvented this problem by using a non-spatial discrimination; however, the cues were informative and interspersed with visual cues which may have affected the attentional effects observed. In the current study, therefore, we used a non-spatial tactile frequency discrimination task following a non-informative tactile white noise cue. When the target was presented 150 ms after the cue, we observed faster discrimination responses to targets presented on the same side compared to the opposite side as the cue; by 1000 ms, responses were significantly faster to targets presented on the opposite side to the cue. Thus, we demonstrated that tactile attentional facilitation can be observed in a non-spatial discrimination task, under unimodal conditions and with entirely non-predictive cues. Furthermore, we provide the first demonstration of significant tactile facilitation and tactile inhibition of return within a single experiment.     

Tele-pain management: use of videoconferencing technology in the delivery of an integrated cognitive-behavioral and physical therapy group intervention

Chronic pain has been recognized as a highly prevalent problem, and interdisciplinary treatments have been shown to be effective in the treatment of chronic pain. An integrated cognitive-behavioral and physical therapy group protocol has been developed and then implemented at remote sites using videoconferencing technology to provide pain management for veterans. The treatment model is summarized and recommendations are made for addressing challenges in implementing this type of treatment via videoconferencing.     

Amount and distribution of study in a personalized instruction course and in a lecture course

The rapid proliferation of courses based on Keller's Personalized System of Instruction (PSI) calls for a prompt evaluation of the relative costs involved in PSI and more traditional forms of college instruction. To determine the cost in student time required by a course taught with PSI relative to lecture, students did their studying in a special Study Center where course materials could be used but not removed. Students in the PSI section spent an average of about 50% more time in the Study Center (46 hr) than did students in the lecture section (30 hr), but that difference was made up by the lecture students spending an average of 20 hr attending lectures. Thus, total preparation time was about the same. PSI students scored slightly higher on common course exams, and while college entrance exam scores correlated highly with course exam scores, Study Center time was reliably related to course exam score only for PSI students. An analysis of the study records of individual students revealed that PSI produced fairly regular patterns of study by all students, while lecture students varied greatly in their patterns.     

The influences of course effort,mastery and performance goals,grade expectancies,and earned course grades on student ratings of course satisfaction

Background. The positive relation between course grades and student ratings of course satisfaction is well established but controversy continues concerning the magnitude, interpretation, and implications of this association. Aims. This study examined the within course relations of a set of variables often implicated as potential contributors to the grade‐student rating relation. Sample. Two‐hundred and twenty students enrolled in an internet‐based university course. Method. Measures of course mastery and performance goals, expected grades, course effort, cumulative GPA, and final course grade were prospectively collected. The dependent variable was a global measure of course satisfaction obtained at the end of the semester. Results. A path model fit the data very well and all study variables directly or indirectly predicted course satisfaction. Grades had a moderately strong effect, half of which was independent of other model variables. Adjusting for all model variables, students high on mastery course goals evaluated the course more positively whereas students high on performance goals provided less favourable evaluations. Conclusions. Students can assess the same course and instructor in different ways depending upon such factors as their degree of success, their motivations for taking the course, and the amount of effort invested. Course satisfaction, then, can be substantially influenced by factors loosely or unrelated to course or teacher effectiveness.     

A microcomputer-dependent statistics and design course

A one-semester course in statistics and research design is described. All computations are carried out by a Macintosh computer. No hand calculation is expected of the students, and little class time is spent on computational procedure. The course covers much more statistical content than is the norm for a one-semester course, and student understanding of the logic of the material and its application is enhanced.     

The Comprehensive Assessment of Psychopathic Personality (CAPP): content validation using prototypical analysis

The Comprehensive Assessment of Psychopathic Personality (CAPP; Cooke, Hart, Logan, & Michie, 2004) is a new personality-based model and clinical assessment of psychopathy. This study was the first to examine the content validity of the English-language CAPP. Content validation is a crucial part of the development and refinement of any new instrument. Prototypical analysis was used to evaluate the representativeness of CAPP symptoms to the psychopathy construct in adults. Symptoms were rated by international mental health professionals (N = 132). Findings support good content validity of the CAPP, with most symptoms rated as highly representative of psychopathy. Domains relating to interpersonal style were particularly prototypical. Confirmatory factor analyses further suggested that CAPP domains are highly unidimensional. However, some CAPP symptoms may be weaker items in the model and further refinement is needed.

Creating Comprehensive and Collaborative Systems

To improve outcomes for children and youth with serious emotional disturbance and their families, we need to create comprehensive and collaborative systems to promote systems change resulting in the development of coherent services built around their individual needs. These services should be family-centered, community-based, and appropriately funded. Unfortunately, barriers to understanding and operationalizing this level of collaboration persist, which challenges the aims of parents, practitioners, policy makers, and others to provide efficient and effective services to these students. I explore the seventh strategic target of the National Agenda for Achieving Better Results for Children and Youth with Serious Emotional Disturbance; provide examples of collaboration that relate to the National Agenda's other six strategic targets; and briefly discuss the present opportunities for and challenges to collaboration.
