Can Detroiters Dream Again? The Imagined Dialectics of Urban Decline in Anthony Bourdain’s Parts Unknown—Detroit

Examining the Detroit episode of Anthony Bourdain’s CNN show, Parts Unknown, this study illuminates how the collective memory of the American dream is ironically projected onto Detroit, the metonymic city of America past. In order to identify the nostalgia of the American dream narrated in the show, we apply the dialectical approach to intercultural communication suggested by Martin and Nakayama and propose the imagined dialectics. Throughout our analyses, we contend that the imagined dialectic narrated in the Parts Unknown episode nostalgically frames Detroit’s past, which inevitably fetishizes its present. We ultimately argue that the nostalgia of the American dream epitomizes the lack of an intercultural and interregional understanding within the US and prevents us from democratic discussion for the betterment of the urban lives.     

Gender Games

This textual analysis focuses on the portrayal of female journalists in House of Cards. The uneven depictions of six female journalists could have a socializing effect on the audience. The researchers argue that the character Zoe Barnes is depicted as childlike, unprofessional, and unethical, while the character Ayla Sayyad is portrayed as a dedicated watchdog journalist. The researchers then explore the ethical implications of these portrayals through the lens of social responsibility theory.     

“Why Aren’t You a Sassy Little Thing”: The Effects of Robot-Enacted Guilt Trips on Credibility and Consensus in a Negotiation

Robots are becoming increasingly popular in social applications and have demonstrated effectiveness in a variety of contexts such as education, health, task management, and other complex cooperative roles. The purpose of this study was to examine human–robot interaction in a nonassistive environment: a negotiation scenario. Specifically, the authors examined what effect message appeals (guilt trip, no guilt trip) and robot agency (principal, agent) had on the negotiation outcomes and perceptions of credibility. Results indicated a significant main effect of agency and an interaction effect between agency and guilt messaging on perceptions of robot credibility such that participants rated a robot agent employing no guilt trips as more credible than one negotiating as principal or one utilizing guilt trips. Neither guilt nor agency had a significant effect on the overall concession of the negotiation task.     

‘Shoot for the moon!’ Students' identities as writers in the context of the classroom

A study of students' identities as writers was carried out in the classroom of a New Zealand primary teacher who had been formally identified by a national body of teachers as having excellent practice in supporting literacy acquisition. The researchers, Professor Janice Wearmouth, from the University of Bedfordshire, Mere Berryman, from the University of Waikato, New Zealand, and Lisa Whittle, from the Department of Conservation, Wellington, New Zealand, aimed to compare high and low literacy achievers' identities as writers within the context of this teacher's pedagogy and the learning environment of her classroom. The researchers concluded that all students, both high and low achievers, were developing very positive writing identities in a context where the teacher's method of supporting her students' writing was very well planned through a process‐writing approach. This teacher had a very high degree of subject and pedagogical content knowledge and an acute awareness of her students' literacy learning needs. Her approach had an immediacy of responsiveness in relation to every student's learning and, above all, had recognition of the overwhelming importance of positive relationships in the classroom, teacher to student and peer to peer.     

‘I can do it,and how!’ Student experience in access and equity pathways to higher education

Alternative pathways and enabling courses such as foundation programmes are well-established in some tertiary institutions and are likely to be broadened and enhanced across the sector. If such a course is designed along the lines of Biggs’ constructive alignment, it would be hoped that students would be likely to adopt a ‘deep approach’ to learning through their course of study. In addition, it is often assumed (but rarely properly demonstrated) that such courses promote the confidence of students to achieve well in their academic studies. This study explored changes in approaches to learning and academic self-efficacy in the first topic of a Foundation Course, using Biggs’ R-SPQ-2F and a newly developed academic self-efficacy scale. While the findings on approaches to learning were inconclusive, analysis showed a substantial and statistically significant increase in academic self-efficacy.     

Is there a low-back cost to hip-centric exercise? Quantifying the lumbar spine joint compression and shear forces during movements used to overload the hips

The aim of this study was to quantify joint compression and shear forces at L4/L5 during exercises used to overload the hips. Nine men performed 36 "walking" trials using two modalities: (1) sled towing and (2) exercise bands placed around the ankles. Participants completed forward, backward, and lateral trials with bent and straight legs at three separate loads. Surface electromyography (EMG) was recorded bilaterally from eight torso and thigh sites, upper body and lumbar spine motion were quantified, and hand forces were measured. An EMG-driven musculoskeletal model was used to estimate the muscular contribution to joint compression and shear. Peak reaction, muscle and joint compression and shear forces, and peak gluteus medius and maximus activity were calculated. Significant differences were noted in each dependent measure; however, they were dependent on direction of travel, leg position, and load. The highest joint compression and shear forces for the sled and band conditions were 4378 N and 626 N, and 3306 N and 713 N, respectively. In general, increasing the band tension had little effect on all dependent measures, although a load-response was found during the sled conditions. Before using any exercise to improve hip function, the potential benefits should be weighed against "costs" to neighbouring joints.     

How accurately does the VIVO Harvester reflect actual Clinical and Translational Sciences Award–affiliated faculty member publications?

Objective:

The research tested the accuracy of the VIVO Harvester software in identifying publications authored by faculty members affiliated with a National Institutes of Health Clinical and Translational Sciences Award (CTSA) site.

Methods:

Health sciences librarians created “gold standard” lists of references for the years 2001 to 2011 from PubMed for twenty-five randomly selected investigators from one CTSA site. These gold standard lists were compared to the same twenty-five investigators'' reference lists produced by VIVO Harvester. The authors subjected the discrepancies between the lists to sensitivity and specificity analyses.

Results:

The VIVO Harvester correctly identified only about 65% of the total eligible PubMed references for the years 2001–2011 for the CTSA-affiliated investigators. The identified references produced by VIVO Harvester were precise yet incomplete. The sensitivity rate was 0.65, and the specificity rate was 1.00.

Conclusion:

While the references produced by VIVO Harvester could be confirmed in PubMed, the VIVO Harvester retrieved only two-thirds of the required references from PubMed. National Institutes of Health CTSA sites will need to supplement VIVO Harvester–produced references with the expert searching skills of health sciences librarians.

Implications:

Health sciences librarians with searching skills need to alert their CTSA sites about these deficiencies and offer their skills to advance their sites'' missions.     

Neural adaptations with sport-specific resistance training in highly skilled athletes

The aim of this study was to assess the effects of variations in the volume and intensity of resistance training in highly skilled athletes on neural adaptive mechanisms: the maximality and pattern of neural drive. The maximality of muscle activation was measured using a high-resolution sample and hold amplifier to record interpolated twitches. The pattern of neural drive was measured by analysing isometric torque-time curves and electromyographic (EMG) characteristics during the performance of rapid isometric contractions at maximal effort. The volume and intensity of training were varied at 4-weekly intervals to systematically emphasize the development of strength, power and motor performance in 14 highly skilled track and field athletes (e.g. discus, hammer, javelin, shot put and weight). Knee extension strength increased significantly by 15% during steady maximal isometric contractions and by 24% during rapid isometric contractions at maximal effort after the 16-week training programme (P < 0.05). Increases in EMG amplitude and rate of EMG activation indicated that improvements to the pattern of neural drive occurred with sport-specific resistance training (P < 0.05). The maximality and pattern of neural drive did not change in the control group.
