Mining service quality feedback from social media: A computational analytics method

In spite of the growing opportunities and demands for using social media to assist government decision-making, few studies have investigated social media sentiments toward public services due to the large volume and noisy nature of big data. Taking a design science approach, this paper suggests a systematic method to assign tweets into each of the SERVQUAL dimensions to identify sentiments and track perceived service quality of healthcare services for policy makers. The method consists of (1) identifying more reliable topic sets through repeated latent Dirichlet allocation (LDA) and clustering; and (2) classifying tweets using topics based on an existing theory for service quality. The method is applied to tweets on the quality of NHS of the UK to demonstrate its usability. We measured social perceptions of healthcare service quality and identified keywords for each SERVQUAL dimension. Moreover, a comparison between the social perceptions derived from the tweets and traditional survey result on the same service quality shows the similarity which confirms the usability of the proposed method. The method has a practical value as a complimentary tool for the more expensive national scale surveys as well as academic value as a novel method integrating text mining with theoretically sound quality framework, SERVQUAL.     

Empowering Staff in Dementia Long-Term Care: Towards a More Supportive Approach to Interventions

This pilot-study aimed to assess a psychoeducational program for staff in care homes. The program was designed to increase knowledge regarding dementia care, promote skills to integrate motor and multisensory stimulation in daily care, and develop coping strategies to manage emotional work-related demands. Six staff members received eight psychoeducational sessions held fortnightly and individualized assistance during the provision of morning care to six residents with dementia. An audio-recorded focus group interview with staff and video recordings of residents' behavior during morning care were made and used to assess the program. Staff reported several benefits: acquisition of new knowledge; demystification of preexisting beliefs related to dementia; group cohesion; self-worth feelings; and positive coping. A trend towards improvements at residents' levels of interaction was found. The findings suggest the need of interventions to go beyond the objectives exclusively centered on staff education and the promotion of residents' well-being. This should be achieved by also allowing workers to feel supported and empowered.     

Faculty Employment Trends in Criminology and Criminal Justice

The academic job search process is perhaps one of the most important and stressful events for scholars hoping to gain full‐time employment in academia. The stress that this process induces is due, at least in part, to the fact that candidates are forced to make important, life‐changing decisions with very little information. The goal of the present study is to provide an update on faculty employment trends in criminology and criminal justice by examining faculty position announcements posted in The Chronicle of Higher Education (CHE) from August 2004 to July 2009. Findings reveal that candidates seeking assistant professor positions will have the most choice, as positions posted at this rank make up the largest category of advertisements. Furthermore, when a specialization was included in the announcement, most departments sought those with a law enforcement focus, followed by generalists.     

Review of The 2009 UNESCO framework for cultural statistics

The main goal of the 2009 UNESCO Framework for Cultural Statistics is to facilitate comparisons through a common understanding of culture and the use of standardized definitions and classifications. This review contains an in-depth analysis of the 2009 Framework's contribution to the existing literature on measuring the economic impact of culture, and it concludes by suggesting future avenues of research. By achieving international consensus on the concept of culture and its measurement, we will be able to progress in our studies of the competitive advantages that allow cultural firms to generate wealth nowadays.     

Using Dialogic Writing Assessment to Support the Development of Historical Literacy

Though discipline-specific approaches to literacy instruction can support adolescents' academic literacy and identity development, scant attention has been paid to ways of targeting such instruction to address individual student needs. Dialogic writing assessment is an approach to conducting writing conferences that foregrounds students' composing process so that teachers can assess and support that process with instructional feedback. Because such feedback is immediate, teachers can observe how students take it up. While dialogic assessment has shown promise as an approach to revealing and supporting students' writing processes in English Language Arts classrooms, it remains to be explored how this approach can support developing writers in other subject areas. This paper offers an analytic narrative account of how a high school social studies teacher used this method to support the writing process of one student, exploring what the method revealed about the challenges the student faced in writing about history, the gaps and misconceptions in their understanding of history and the intersection between the two. We discuss how certain ‘mediational moves’ the teacher employed enabled the student to compose collaboratively with the teacher, and in this collaborative composing, to capture ideas that she later used in her independent writing.     

Discrete-time synchronization strategy for input time-delay mobile robots

This paper considers a synchronization strategy for a group of differentially driven mobile robots subject to input time-delayed control signals. The continuous time model of the vehicles is exactly discretized in order to obtain a larger dimension representation free of delays. The control strategy is based on the concept of synchronization, under two main assumptions: a specific formation for the group of robots and the tracking of a particular desired trajectory. The control strategy proposed in this work allows the consideration of causal feedback laws avoiding the use of an additional prediction strategy that counteracts the undesired input time-delay effects. The performance of the synchronization strategy is evaluated by real-time experiments with the help of a group of three mobile robots and an indoor absolute localization system based on artificial vision.     

Characteristics and publication patterns of theses from a Peruvian medical school

Background: Many medical schools require a student thesis before graduation. Publishing results in a peer‐reviewed journal could be an indicator of scientific value and acceptability by the scientific community. The publication pattern of theses published by medical students in Peru is unknown. The aim of this study was to assess the characteristics and publication pattern of theses in biomedical‐indexed journals conducted by medical students in a university with the highest research output in Peru. Methods: Data from registered theses between 2000 and 2003 were obtained from the university library. Publication of theses in biomedical journals was assessed in 2008 by a search strategy using PubMed, Google Scholar, LILACS, LIPECS and SciELO. Results: Four hundred and eighty‐two medical theses were registered between 2000 and 2003; 85 (17.6%) were published in biomedical‐indexed journals. Of the published theses, 28 (5.8%) were published in MEDLINE‐indexed journals, 55 (11.4%) in SciELO‐indexed journals, 61 (12.6%) in LILACS‐indexed journals and 68 (14.1%) in LIPECS‐indexed journals. Most of the published theses (80%) were in Spanish and published in Peruvian journals; and 17 theses (20%) were published in foreign journals (all of them indexed in MEDLINE). In addition, 37 (43.5%) belong primarily to internal medicine, and 24 (28.2%) belong primarily to infectious diseases. Medical students were first authors in 71 (83.5%) of the articles. Conclusion: In this study, most of the published theses were in Spanish, published in local journals and indexed in LIPECS. The percentage of published theses in biomedical journals at this university is comparable with others coming from developed countries.     

Mentoring College Students: A Critical Review of the Literature Between 1990 and 2007

In response to the mounting national support provided to mentoring programs and initiatives in higher education, the present article updates a review article written by Jacobi (Rev Educ Res 61(4):505–532, 1991). The article revisits the mentoring literature in an attempt to re-frame and update the definition and characteristics of mentoring provided by Jacobi. It also synthesizes and critically analyzes empirical literature specific to mentoring college students published between 1990 and 2007. Finally, the article presents broad theoretical perspectives of mentoring from the business, psychology and education literature in preface to a proposed theoretical framework specific to mentoring college students. The article concludes with specific recommendations to advance the mentoring literature.
