Barriers in Case Managers’ Roles: A Qualitative Systematic Review
Authors: Joo Jee Young , Huber Diane L.
Published: September 2017

The challenges faced by case managers when implementing case management have received little focus. Several qualitative studies have been published that may be able to shed light on those challenges. This study is a systematic review of qualitative literature to identify barriers case managers have when implementing case management. Five electronic bibliographic databases were systematically searched, and 10 qualitative studies were identified for inclusion in the review which were published from 2007 to 2016. Through thematic synthesis of findings, five themes were identified as barriers to case management implementation: unclear scope of practice, diverse and complex case management activities, insufficient training, poor collaboration with other health-care providers, and client relationship challenges. This review study suggested that standardized evidence-based practical protocols and certification programs may help overcome case managers’ barriers and improve case management practices. Health policymakers, case management associations, and health-care management researchers should develop educational and practical supports for case managers.
Introduction: Elites and Power after Financialization
Authors: Davis Aeron , Williams Karel
Published: September 2017

This article introduces the special issue on ‘Elites and Power after Financialization’. It is presented in three parts. The first sets out the original Weberian problematic that directed the work of Michels and Mills, in the 1910s and 1950s respectively. It then discusses how this framework was appropriated and then cast aside as our understanding of capitalism changed. The second section makes the case for a reset of elite studies around the current capitalist conjuncture of financialization. It is explained how this unifying theme allows for a diverse set of approaches for answering old and new questions about elites and power. The third part identifies four key themes or sites of investigation that emerge within the nine papers offered here. These are: new state-capital relations, innovative forms of value extraction, new elite insecurities and resources in liquid times and the role of elite intermediaries and experts.
The Component Timed-Up-and-Go test: the utility and psychometric properties of using a mobile application to determine prosthetic mobility in people with lower limb amputations
Authors: Clemens Sheila M , Gailey Robert S , Bennett Christopher L , Pasquina Paul F , Kirk-Sanchez Neva J , Gaunaurd Ignacio A
Published: September 2017

Objective:

Using a custom mobile application to evaluate the reliability and validity of the Component Timed-Up-and-Go test to assess prosthetic mobility in people with lower limb amputation.

Design:

Cross-sectional design.

Setting:

National conference for people with limb loss.

Subjects:

A total of 118 people with non-vascular cause of lower limb amputation participated. Subjects had a mean age of 48 (±13.7) years and were an average of 10 years post amputation. Of them, 54% ( n = 64) of subjects were male.

Intervention:

None.

Main measure:

The Component Timed-Up-and-Go was administered using a mobile iPad application, generating a total time to complete the test and five component times capturing each subtask (sit to stand transitions, linear gait, turning) of the standard timed-up-and-go test. The outcome underwent test–retest reliability using intraclass correlation coefficients (ICCs) and convergent validity analyses through correlation with self-report measures of balance and mobility.

Results:

The Component Timed-Up-and-Go exhibited excellent test–retest reliability with ICCs ranging from .98 to .86 for total and component times. Evidence of discriminative validity resulted from significant differences in mean total times between people with transtibial (10.1 (SD: ±2.3)) and transfemoral (12.76 (SD: ±5.1) amputation, as well as significant differences in all five component times ( P < .05). Convergent validity of the Component Timed-Up-and-Go was demonstrated through moderate correlations with the PLUS-M ( rs = −.56).

Conclusion:

The Component Timed-Up-and-Go is a reliable and valid clinical tool for detailed assessment of prosthetic mobility in people with non-vascular lower limb amputation. The iPad application provided a means to easily record data, contributing to clinical utility.
Spatial perspectives on knowledge brokers: Evidence from Brussels
Authors: Dotti Nicola Francesco , Spithoven André
Published: September 2017

Knowledge brokers have emerged as a new type of actors shaping scientific production, influencing science–policy relationships, and thereby contributing to regional competitiveness. Yet, the spatial dimension of these knowledge brokers has received little attention. Using Framework Programme participations in European cities, we analyse and discuss the location strategy of knowledge brokers, highlighting the importance of co-location with the funding source. Our findings show that knowledge brokers are clustered in Brussels, and not elsewhere, to be closer to the European Commission in order to access strategic, informal and tacit information, while contributing to the construction of transnational R&D networks. While this ‘local buzz’ has positive side effects on the regional innovation system of Brussels; knowledge brokers emerge as a new type of spatially clustered actors shaping the distribution of EU funding for ‘European knowledge pipelines’.
The Therapeutic Effect of Intra-articular Normal Saline Injections for Knee Osteoarthritis: A Meta-analysis of Evidence Level 1 Studies
Authors: Saltzman Bryan M. , Leroux Timothy , Meyer Maximilian A. , Basques Bryce A. , Chahal Jaskarndip , Bach Bernard R. , Yanke Adam B. , Cole Brian J.
Published: September 2017

Background:

Intra-articular normal saline (IA-NS) injections have been utilized as a placebo in a number of randomized controlled trials pertaining to the management of knee osteoarthritis (OA); however, it is believed that these “placebo” injections may have a therapeutic effect that has not been quantified in the literature.

Purpose:

To (1) quantify the effect of IA-NS injections on patient-reported outcomes (PROs) and (2) compare postinjection PROs to established minimal clinically important difference (MCID) criteria to demonstrate a potential therapeutic effect.

Study Design:

Meta-analysis.

Methods:

A review was conducted to identify all randomized, placebo-controlled trials on injection therapy for knee OA between 2006 and 2016. Patient demographics and PROs before the injection and at 3 and 6 months after the injection were collected for patients in the IA-NS injection group in each study. A random-effects model was used to compare preinjection scores and scores at each postinjection time point in a pairwise fashion.

Results:

In total, there were 14 placebo cohorts in 13 studies that were analyzed after meeting inclusion criteria for this meta-analysis. This included 1076 patients (Kellgren-Lawrence grade 1-4), with a weighted mean age of 62.53 years and mean body mass index of 28.67 kg/m2. There was only sufficient information to perform analyses of visual analog scale (VAS) pain and Western Ontario and McMaster Universities Arthritis Index (WOMAC) total scores. At 3 months after the IA-NS placebo injection, there was a significant improvement in VAS pain scores (mean difference [MD], 12.10 [95% CI, 3.27 to 20.93]; P = .007), whereas improvement in the WOMAC total scores approached but did not reach statistical significance (MD, 19.75 [95% CI, –0.50 to 40.09]; P = .06). At 6 months, both VAS pain scores (MD, 16.62 [95% CI, 12.13-21.10]; P < .00001) and WOMAC total scores (MD, 11.34 [95% CI, 7.03-15.65]; P < .00001) were significantly improved in comparison to preinjection values. Furthermore, improvements in both the VAS pain and WOMAC total scores at 6 months were clinically significant (MCID, 1.37 and 9, respectively).

Conclusion:

The administration of an IA-NS placebo injection yields a statistically and clinically meaningful improvement in PROs up to 6 months after the injection in patients with knee OA. This observation supports the notion that the so-called placebo effect for IA-NS injections achieves a clinically meaningful response in patients with OA when provided during comparison studies to an active treatment group (ie, hyaluronic acid).
Bodies in plural
Authors: Bottici Chiara
Published: September 2017

In the last few years, it has become a commonplace to state that domination takes place through a multiplicity of axes, where gender, class, race, and sexuality intersect with one another. While a lot of insightful empirical work is being done under the heading of intersectionality, it is very rarely linked to the anarchist tradition that preceded it. In this article, I would like to articulate this point by showing the usefulness but also the limits of the notion of intersectionality to understand mechanisms of domination and then move on to argue for the need of an anarcha-feminist research program. Secondly, I will try to provide the philosophical framework for such an enterprise by arguing that it is in a Spinozist ontology of the transindividual that we can best find the conceptual resources for thinking about the plural nature of women’s bodies and thus of their oppression. This will allow me to attempt to articulate the question of ‘what it means to be a woman’ in pluralistic terms and thus also to defend a specifically feminist form of anarchism. In conclusion, I will go back to the anarcha-feminist tradition and will show why today it is the best possible ally of feminism in the pursuit of a critical theory of society.
Quality Improvement Initiative to Reduce Pediatric Intensive Care Unit Noise Pollution With the Use of a Pediatric Delirium Bundle

Published: September 2017

Objectives:

Noise pollution in pediatric intensive care units (PICU) contributes to poor sleep and may increase risk of developing delirium. The Environmental Protection Agency (EPA) recommends <45 decibels (dB) in hospital environments. The objectives are to assess the degree of PICU noise pollution, to develop a delirium bundle targeted at reducing noise, and to assess the effect of the bundle on nocturnal noise pollution.

Methods:

This is a QI initiative at an academic PICU. Thirty-five sound sensors were installed in patient bed spaces, hallways, and common areas. The pediatric delirium bundle was implemented in 8 pilot patients (40 patient ICU days) while 108 non-pilot patients received usual care over a 28-day period.

Results:

A total of 20,609 hourly dB readings were collected. Hourly minimum, average, and maximum dB of all occupied bed spaces demonstrated medians [interquartile range] of 48.0 [39.0-53.0], 52.8 [48.1-56.2] and 67.0 [63.5-70.5] dB, respectively. Bed spaces were louder during the day (10AM to 4PM) than at night (11PM to 5AM) (53.5 [49.0-56.8] vs. 51.3 [46.0-55.3] dB, P < 0.01). Pilot patient rooms were significantly quieter than non-pilot patient rooms at night (n=210, 45.3 [39.7-55.9]) vs. n=1841, 51.2 [46.9-54.8] dB, P < 0.01). The pilot rooms compliant with the bundle had the lowest hourly nighttime average dB (44.1 [38.5-55.5]).

Conclusions:

Substantial noise pollution exists in our PICU, and utilizing the pediatric delirium bundle led to a significant noise reduction that can be perceived as half the loudness with hourly nighttime average dB meeting the EPA standards when compliant with the bundle.
‘Chicken and Duck Talk’: Life and Death of Language Training at a Japanese Multinational in China
Authors: Zheng Yu , Smith Chris
Published: September 2017

This article examines social relations in language learning through a case study of two cohorts of Chinese workers in a Japanese multinational company (MNC). The two cohorts weigh learning Japanese in the context of internal and external opportunities, and pursue different strategies – deliberative acquisition and deliberative opposition. Exploring the broader meanings of language learning beyond skill acquisition, the article suggests that language is more than an individual asset or a common code for workers to build collective power. Social reproduction of language is embedded in workers’ choice of pathways for social mobility which was created in the social transition and has shifted over time in China. These findings make a contribution to the sociology of language training in work, by challenging structural and cultural theories that underplay the agency of workers in assessing language as a resource for labour power development.
Simultaneous attack strategy against a maneuvering target with unknown acceleration
Authors: Hu Zilun , Yang Jianying
Published: September 2017

This paper is concerning the simultaneous attack problem with multiple missiles against a maneuvering target with unknown acceleration. The new guidance protocol, which avoids using the time-to-go information, ensures the simultaneous attack based on the consensus of the range-to-go and the approaching rate of each missile. This strategy is a distributed guidance law where each missile can only get information from neighbors. The consensus of the missiles is shown mathematically as well as with extensive simulations.
A comparison of researcher–practitioner collaborations in library and information science, education, and sociology
Authors: Chang Yu-Wei
Published: September 2017

This study used coauthorship analysis to investigate trends in researcher–practitioner collaborations by examining articles published between 2005 and 2014 in the disciplines of library and information science, education, and sociology. The results revealed that articles coauthored by researchers were the main type of research collaboration in these three disciplines. Articles coauthored by researchers and practitioners were the third largest type of research collaboration in all three disciplines; the percentage of such articles in library and information science (14.2%) was considerably higher than that in education (6.1%) and sociology (2.7%). A slightly decreasing trend was observed in these articles in library and information science, but a slightly increasing trend was identified in education and sociology. Regarding authorship, library and information science practitioners were more active than were education and sociology practitioners. Librarians, governmental staff, and administrators were the dominant practitioner authors of this type of article in library and information science, sociology, and education, respectively.
Steady-state pharmacokinetics of hydroxychloroquine in patients with cutaneous lupus erythematosus
Authors: Al-Rawi H , Meggitt S J , Williams F M , Wahie S
Published: September 2017

Background

Hydroxychloroquine (HCQ), a 4-aminoquinolone antimalarial, is regarded as the oral therapy of choice for cutaneous and systemic lupus erythematosus (SLE). It is also licensed for rheumatoid arthritis (RA). Studies of HCQ-treated patients with SLE or RA have demonstrated a positive correlation between whole-blood HCQ levels and clinical response. Such studies have involved measuring whole-blood concentrations at any given time point after HCQ ingestion assuming that steady-state concentrations would undergo limited fluctuation over a daily interval because HCQ has a long half-life. This approach might not sufficiently take into account the potential intra-patient variation in HCQ blood levels that can occur over a 24-hour period. Such variation, if significant, could affect the credibility of any concentration-response relationship provided from these previous studies.

Objectives

The objectives of this report are to: (a) investigate the intra-patient variation in HCQ whole-blood levels and (b) suggest an optimum time for sampling patients for future studies.

Methods

Six patients were recruited with cutaneous lupus erythematosus who had each been on HCQ 200 mg twice daily for at least six months, so that they were at steady-state. Each patient was fasted overnight and had standardized meals and dosing schedule. Whole blood was sampled at seven time points over 24 hours. Whole-blood HCQ levels were measured with high-performance liquid chromatography using gradient elution, fluorimetric detection and chloroquine as an internal standard. The assay had a mean inter- and intra-day coefficient of variation of 10% and 5% respectively and a limit of detection of 5ng/ml.

Results

HCQ levels appeared to follow a biphasic pattern over the sampling period. Maximum levels were noted a median of four hours (range 2–6) after ingestion. Median intra-patient variation between trough and peak levels, ‘Cmax’ ((peak – trough)/trough × 100%), was 27% (range 8–150%).

Conclusions

This study demonstrated that whole-blood HCQ levels vary 27% (median, range 8–150%) within an individual over a 12-hour period. Drug levels might differ between individuals because of multiple factors, including variable adherence to medication. Measuring HCQ levels for assessment of drug adherence could be valuable in the ‘real-world’ clinical setting. This could be assessed by taking a blood sample at any time following HCQ ingestion. If patients were found to have very low or undetectable levels of HCQ, non-adherence to HCQ should be suspected.
Rise of Born Globals and Their Association with High Technology Intensity or Services Sector— Myths or Reality?
Authors: Singh Suresh
Published: September 2017

Literature suggests that the proportion of born globals—firms entering foreign countries soon after birth—has increased significantly over time and that such firms are associated with high-technology-intensity or services sector. However, there is little empirical support for these claims. To address this gap, this article presents an empirical analysis of age at the first global entry of US manufacturing and service multinationals that entered foreign countries in the last century. Only manufacturing showed a significant rise in the number of born globals. Being born global was not correlated with either having a high-technology-intensity or being a service firm.
Tale of Two Cities of South Asia: Consequences of Changes in the nature of Manufacturing on Dhaka and Kolkata
Authors: Seth Vijay K.
Published: September 2017

In the present article, the author is narrating the tale of two cities located in the eastern part of the Indian subcontinent: Dhaka and Kolkata. These two cities have shared a common historical time since the beginning of the Mughal Empire and experienced the consequences of the three different political regimes: (a) Mughal Empire, (b) rules of the East India Company and (c) British Raj. The symbiotic relationship that emerged between these two cities depended on the changes in the nature of manufacturing. The existence of traditional flexible manufacturing resulted in the prosperity of Dhaka and the origin of modern manufacturing shifted prosperity from Dhaka to Kolkata. In the article, an attempt has been made to describe how different political regimes impacted the nature of manufacturing to explain how forces of development and prosperity kept changing their location.
The future of career education in New Zealand secondary schools: A review of the literature
Authors: Yates Anne , Bruce Megan
Published: September 2017

Traditionally career education in New Zealand secondary schools has been provided by a dedicated career advisor, but the effectiveness of this model is increasingly being questioned. This review examined approaches to career education in order to recommend a more appropriate model for the future. A review of 14 articles revealed that career education is increasingly important for secondary school students and that advantages exist in an integrated whole-school approach. The authors argue that such an approach is desirable, but acknowledge the issues to be addressed to ensure success. These include professional development for career advisors, principals and teachers, changing entrenched attitudes, reimagining the role of the career advisor and providing increased resourcing. While this review is focussed on New Zealand, it is apparent that other countries are grappling, similarly, with the issue of career education for secondary school students.
Employability and student equity in higher education: The role of university careers services
Authors: Andrewartha Lisa , Harvey Andrew
Published: September 2017

There is a pressing need to redress inequities in university completion rates and graduate outcomes. Students from low socio-economic status, regional, and Indigenous backgrounds have lower completion rates than their peers. Graduates from non-English speaking backgrounds and graduates with a disability have consistently worse employment outcomes. Despite these concerning trends, student equity remains marginal to most university employability strategies, including the provision of careers services. University careers services are a central resource for improving student employability. These services provide a range of activities such as careers education, job interview training, resumé preparation, and the sourcing of employment opportunities. Research suggests that students from equity groups underutilise careers services, despite often having the most to gain from them. We captured the professional perspectives and expertise of university careers specialists to explore: the role of careers services in improving employability and equity; and broader university strategies to redress inequitable graduate outcomes.
Early career development in the public sector: Lessons from a social constructionist perspective
Authors: Bridgman Todd , De’ath Annie
Published: September 2017

This article explores the contribution a social constructionist paradigm can make to the study of career, through a small-scale empirical study of recent graduates employed in New Zealand’s state sector. A social constructionist lens denies the possibility of an individualised, generalised understanding of ‘career’, highlighting instead its local, contingent character as the product of social interaction. Our respondents’ collective construction of career was heavily shaped by a range of context-specific interactions and influences, such as the perception of a distinctive national identity, as well as by their young age and state sector location. It was also shaped by the research process, with us as researchers implicated in these meaning-making processes. Social constructionism shines a light on aspects of the field that are underplayed by mainstream, scientific approaches to the study of career, and therefore has valuable implications for practitioners, as well as scholars.
Pulmonary Adenocarcinoma, Intra-alveolar Variant: A Rare Entity Mimicking Desquamative Interstitial Pneumonia
Authors: Hirsch Eric , Jagirdar Jaishree , Nazarullah Alia
Published: September 2017

Exclusive discohesive tumor cells within intra-alveolar spaces is a rare pattern of involvement of primary and metastatic lung tumors. In the absence of a tumoral mass, this pattern closely mimics desquamative interstitial pneumonia (DIP) clinically, radiologically, and histologically. However, a secondary DIP pattern may be seen adjacent to a tumor mass not infrequently. Here, we describe a case of a 64-year-old woman status post bilateral lung transplantation, who was radiologically thought to have an interstitial lung disease. The autopsy lung specimen revealed extensive involvement by intra-alveolar adenocarcinoma, with a cytomorphology mimicking alveolar macrophages as seen in DIP in the absence of a tumoral mass. The presence of subtle clustering with signet ring cell features and rare micropapillae were an important clue to the diagnosis. The tumor cells were positive for CK7, napsin-A, and TTF-1, and negative for CD68. This case represents an unusual variant of pulmonary adenocarcinoma with a pure intra-alveolar pattern of involvement, mimicking DIP. To the best of our knowledge, excluding biopsy specimens, only one similar case has been reported in the literature and none in the posttransplant setting.
A Precious Diagnostic “Pearl”: The Necklace Pattern in Germ Cell Tumors of the Testis
Authors: Snow Justin , Mosquera Juan Miguel , Scognamiglio Theresa , Robinson Brian D. , Khani Francesca
Published: September 2017

Diffuse embryoma is a rare pattern of nonseminomatous germ cell tumor of the testis originally described in 1983. We report a case with this predominant pattern in an 18-year-old male with a painless palpable testicular mass. Although it is relatively common to see a diffuse embryoma pattern focally in mixed nonseminomatous germ cell tumors of the testis, it is rarely the predominant pattern and can represent a diagnostic pitfall on routine hematoxylin and eosin stain. We emphasize the importance of recognizing the individual components within the diffuse embryoma pattern, review the literature, and briefly discuss the ancillary immunohistochemical stains that may be utilized to help support the diagnosis.
Linear vibrations of triple-walled carbon nanotubes
Authors: Strozzi Matteo , Pellicano Francesco
Published: September 2017

In this paper, the linear vibrations of triple-walled carbon nanotubes (TWNTs) are investigated. A multiple elastic thin shell model is applied. The TWNT dynamics is studied in the framework of the Sanders–Koiter shell theory. The van der Waals interaction between any two layers of the TWNT is modelled by a radius-dependent function. The shell deformation is described in terms of longitudinal, tangential and radial displacements. Simply supported, clamped and free boundary conditions are applied. The three displacement fields are expanded by means of a double mixed series based on Chebyshev polynomials for the longitudinal variable and harmonic functions for the tangential variable. The Rayleigh–Ritz method is applied to obtain approximate natural frequencies and mode shapes. The present model is validated in the linear field by means of comparisons with data from the literature. This study is focused on determining the effect of geometry and boundary conditions on the natural frequencies of TWNTs.
Development of a Systems Science Curriculum to Engage Rural African American Teens in Understanding and Addressing Childhood Obesity Prevention
Authors: Frerichs Leah , Hassmiller Lich Kristen , Young Tiffany L. , Dave Gaurav , Stith Doris , Corbie-Smith Giselle
Published: September 2017

Engaging youth from racial and ethnic minority communities as leaders for change is a potential strategy to mobilize support for addressing childhood obesity, but there are limited curricula designed to help youth understand the complex influences on obesity. Our aim was to develop and pilot test a systems science curriculum to elicit rural African American youth perspectives on childhood obesity and enhance their understanding of and support for obesity prevention solutions. The curriculum was designed so it could be integrated with existing positive youth development curricula that help youth advocate for and implement identified solutions. We conducted four workshop sessions with youth that engaged them in systems learning activities such as guided systems diagramming activities. The participants ( n = 21) completed validated surveys presession and postsession that assessed their causal attributions of obesity and support for obesity prevention policies. The youths’ perception that environmental factors cause obesity increased ( p < .05), and perceptions that individual behavior and biology cause obesity did not change. Their support for policies that addressed food access and food pricing significantly increased ( p < .05). The youths’ system diagrams elucidated links between multilevel factors such as personal attitudes, social influence, and the built environment, which provides important information for designing synergistic solutions. The changes we observed in youths’ perceptions of obesity and support for policy changes have important implications for youths’ interest and willingness to advocate for social and environmental changes in their community. The strategies have a promising role in supporting community mobilization to address childhood obesity.
Optimized parallel simulations of analytic bond-order potentials on hybrid shared/distributed memory with MPI and OpenMP
Authors: Teijeiro Carlos , Hammerschmidt Thomas , Drautz Ralf , Sutmann Godehard
Published: September 2017

Analytic bond-order potentials (BOPs) allow to obtain a highly accurate description of interatomic interactions at a reasonable computational cost. However, for simulations with very large systems, the high memory demands require the use of a parallel implementation, which at the same time also optimizes the use of computational resources. The calculations of analytic BOPs are performed for a restricted volume around every atom and therefore have shown to be well suited for a message passing interface (MPI)-based parallelization based on a domain decomposition scheme, in which one process manages one big domain using the entire memory of a compute node. On the basis of this approach, the present work focuses on the analysis and enhancement of its performance on shared memory by using OpenMP threads on each MPI process, in order to use many cores per node to speed up computations and minimize memory bottlenecks. Different algorithms are described and their corresponding performance results are presented, showing significant performance gains for highly parallel systems with hybrid MPI/OpenMP simulations up to several thousands of threads.
The State of Ethnic Dermatology in Canada
Authors: Ogunyemi Boluwaji , Miller-Monthrope Yvette
Published: September 2017

Approximately 30% of Canadians will be members of a visible minority by 2031. When dermatology became an independent medical discipline in the late 18th and early 19th centuries, most residents of Canada and the United States were of Northern European descent. Morphology and descriptions of dermatoses are based on patients with light skin. Skin of colour dermatology refers to a unique field in dermatology dedicated to the diagnosis and management of disorders that are more prevalent in patients with moderately to richly pigmented skin. Important differences in the presentation of common dermatoses such as seborrheic dermatitis and acne exist in patients with darker skin types. The effect of traditional treatments for common and uncommon dermatoses is also an important consideration in managing patients with skin of colour. Such treatments may result in adverse effects such as postinflammatory hyperpigmentation or keloid scarring at a higher rate. Most respondents from a 2013 UK study of dermatology residents and consultants agreed that individuals with ‘ethnic skin’ had specific and unique dermatological problems. The Royal College of Physician and Surgeons of Canada’s Objectives of Training in Dermatology states that residents must demonstrate the requisite knowledge, skills, and attitudes for effective patient-centred care and service to a diverse population. Future steps include creating a national society of dermatologists interested in clinical and academic aspects of ethnic dermatology. As well, presentations on skin of colour dermatology could be encouraged at major Canadian dermatology meetings.
On not taking the self seriously: Resilience, relatability and humour in young women’s Tumblr blogs
Authors: Kanai Akane
Published: September 2017

In a contemporary neoliberal landscape, young women are subject to intensified requirements to demonstrate resilient individuality while also enacting a pleasing, approachable femininity, in domains of life including bodily appearance, education, employment and personal productivity in general. Following Arlie Hochschild’s work on emotional labour, I suggest normative youthful femininity is lived, not simply as a set of life regulations, but as a set of ‘feeling rules’ through which young women affectively manage such contradictions. Feeling rules shape how young women may feel in relation to gendered regulation, limiting their articulation of managing this burden to humorous, upbeat quips in the genre of safe, funny, ‘girlfriendly’ material. I examine a set of self-representative blogs authored by young women on the platform Tumblr to explore how these rules are navigated. Converting the frustrations of postfeminist regulation into funny, bite-sized moments, the blogs produce selves amenable to circulation in a gendered, digital economy of relatability.
Digital, ethical, political: Network time and common responsibility
Authors: Hassan Robert
Published: September 2017

The essay argues that a proper ethical foundation for the political processes underlying liberal democracy is unattainable in a globalized society made possible through networked computers – and the transformed relationship with temporality that is generated by them. The essay brings together the computer ethics of Norbert Wiener and the temporal ethics of Hans Jonas to show that both original visions for a better world are unrealizable in the unanticipated context of what is termed ‘network time’. The essay argues further that to develop an ethical basis for liberal democracy, digital logic and its effects must be contrasted with that which they ceaselessly colonize and marginalize today: an irreducibly analogue world, with analogue politics, analogue technologies and analogue humans who conceived and developed liberal democracy as a cornerstone of the project of Enlightenment. Through contrast and critique, the essay reveals the difficulty for any ethico-political project within the digital and argues that the present post-modern relationship with computing, in which ‘market forces’ determine technological forms and applications, is socially destructive and must be brought under a new aegis of democratic and common responsibility.
Mechanical design of flywheels for energy storage: A review with state-of-the-art developments
Authors: Dragoni Eugenio
Published: September 2017

For years, engineers and designers have capitalized on electrochemical batteries for long-term energy storage, which can only last for a finite number of charge–discharge cycles. More recently, compressed hydrogen is being scrutinized as a large-scale storage medium but this poses the risk of spreading high-pressure vessels with inflammable content. Historically, flywheels have provided an effective way to smooth out speed fluctuations in irregular machines and mechanisms. With advancements in composite materials, magnetic bearings, and mechatronic drives, flywheels have become the subject of extensive research as power storage devices for mobile or fixed installations. Flywheel energy storage systems are considered to be an attractive alternative to electrochemical batteries due to higher stored energy density, higher life term, deterministic state of charge and ecological operation. The mechanical performance of a flywheel can be attributed to three factors: material strength, geometry, and rotational speed. Focusing on the simple relationship between these variables, this paper reviews the literature of flywheel technology and explores the merits of four simple but unconventional flywheel configurations that have not been examined so far. Two geometries assume the use of monolithic isotropic materials two solutions are based on the use of high-strength strips or tapes wound up to form a multilayered structure.
Can foundations solve the journalism crisis?
Authors: Benson Rodney
Published: September 2017

In the context of the ongoing financial crisis in U.S. professional journalism, philanthropic foundation-supported nonprofits are increasingly proposed as a solution to the under-provision of civic-oriented news production. Drawing on an analysis of the social composition of boards of directors and interviews with foundation officials and nonprofit journalists, this article examines both the civic contributions and limitations of foundation-supported nonprofit news organizations. Foundations are shown to place many nonprofits in a Catch-22 because of competing demands to achieve both economic “sustainability” and civic “impact,” ultimately creating pressures to reproduce dominant commercial media news practices or orient news primarily for small, elite audiences. Further, media organizations dependent on foundation project-based funding risk being captured by foundation agendas and thus less able to investigate the issues they deem most important. Reforms encouraging more long-term, no-strings-attached funding by foundations, along with development of small donor and public funding, could help nonprofits overcome their current limitations.
Moral economies of consumption
Authors: Wheeler Kathryn
Published: September 2017

The aim of this article is twofold: first, to bring together debates about enduring normative concerns surrounding the morality of consumption with more recent concerns about the ways specific moralities are constituted in and through markets. The second aim is to develop the concept of ‘moral economy’ and call for an approach to its study, attentive to how moralities of consumption develop through interactions between instituted systems of provision, forms of state regulation, customs within communities and the everyday reflections of consumers about the things that matter to them. As consumers are increasingly asked to factor environmental and fair labour concerns into their purchase and post-purchase habits, there is a real need to understand how moralities of consumption are both formatted through institutional frameworks and shaped everyday by actors from within. After developing a framework for the study of moral economies, this article explores in depth the experiences of one couple in relation to the cessation of a cardboard recycling collection in Shropshire (England) to show why a multilevel perspective is needed to appreciate the place of morality within the market.
Understanding (and Acting On) 20 Years of Research on Violence and LGBTQ + Communities

Questions related to violence, vulnerability, and sexual and gender minorities continuing to occupy a focal place in U.S. public discourse. We reviewed findings from 20 years of research on that topic to make recommendations for policy, practice, and future research. This article synthesizes findings from 102 peer-reviewed articles as well as a small number of unpublished studies and grey literature. We found no data to support the idea (widespread in popular discourse) that those in the sexual or gender majority require protection from sexual or gender minority individuals. Instead, this wide body of research indicates that sexual and gender minorities are themselves at elevated risk for physical and sexual assault, harassment, bullying, and hate crime victimization throughout childhood, adolescence, and adulthood. Contradicting the image of hate crimes as perpetrated by strangers or acquaintances, we find that bias-related verbal abuse, physical, and sexual assault by close family members contribute heavily to observed victimization rates. Further, despite the perception that society is becoming more welcoming, victimization disparities appear to be stable or widening since the 1990s. More studies with probabilistic sampling approaches, standardized measures, and larger samples of gender minorities are needed. However, widespread victimization of sexual and gender minorities is clearly an urgent issue, demanding attention from clinicians, program developers, and policy makers.
Diagnostic Utility of the Shortened Version of the Wisconsin Card Sorting Test in Patients With Sporadic Late Onset Alzheimer Disease
Authors: Sánchez Juan Luis , Martín Javier , López Carolina
Published: September 2017

Background:

The classic version of the Wisconsin Card Sorting Test (WCST) consists of correctly sorting 128 cards according to changing sorting criteria. Its application is costly in terms of the time employed, with all the negative consequences this entails (decrease in motivation, frustration, and fatigue).

Method:

The main objective of this study was to test the usefulness of the shortened version of the WCST as compared to the full test by analyzing the equivalence between the two decks comprising the full 128-card version on a sample of patients diagnosed with sporadic late onset Alzheimer disease (SLOAD) and to check its clinical usefulness.

Results:

The variables showed equivalence between the two decks and their ability to differentiate between the control group (CG) and the Alzheimer disease (AD) group.

Conclusion:

The scores obtained suggest equivalence between decks and that the application of only the first deck is sufficient.

Background:

Aortitis is a rare condition with inflammatory or infectious etiology that can be difficult to diagnose due to the highly variable clinical presentation and nonspecific symptoms. However, current literature on the diagnosis, management, and prognosis of aortitis is extremely scarce.

Methods:

We retrospectively reviewed all patients’ charts who were diagnosed with giant cell arteritis, Takayasu arteritis, or noninfectious aortitis presenting at a single center between January 1, 2009, and April 17, 2015. Data collected included demographics, medical history, comorbidities, laboratory and imaging data, management, and outcome.

Results:

Among the included 15 patients presenting with aortitis at our center, 53% were diagnosed with Takayasu arteritis, 33% with idiopathic inflammatory aortitis, and 13% with giant cell arteritis. All patients received steroid treatment, 67% received adjunctive immunosuppressants or immunomodulators, and 33% underwent interventional procedures. Based on clinical presentation and laboratory and imaging findings at the last follow-up visit for each patient, 67% showed improvement, 27% had no change in disease activity, and 7% had a progression of the disease.

Conclusions:

Takayasu arteritis was found to be more common than idiopathic inflammatory aortitis and giant cell arteritis among our 15 cases diagnosed with aortitis. All patients received medical therapy and 33% received interventional procedures, leading to 67% improvement of disease activity or related complications. This article also offers a comprehensive review of the diagnosis, management, and outcome of aortitis, supplementing the very limited literature on this disease.
Time Spent Sitting as an Independent Risk Factor for Cardiovascular Disease
Authors: Henschel Beate , Gorczyca Anna M. , Chomistek Andrea K.
Published: September 2017

Sedentary behavior is highly prevalent despite growing evidence of adverse effects on the cardiovascular and metabolic system that are independent of the level of recreational physical activity (PA). We present results for the association between sitting time and cardiovascular disease (CVD) from selected cohort and cross-sectional studies published in or after the year 2010 according to the domains where sitting time is accumulated during the day. These include TV viewing, occupational sitting, and sitting during transportation as well as overall sitting. The outcomes considered in this review are total CVD, coronary heart disease, and stroke as well as CVD risk factors—namely, hypertension, hypercholesterolemia, and type 2 diabetes and their associated biomarkers. Finally, several current issues with regard to studying the effects of sitting time on CVD are discussed, including how sedentary behavior is assessed, isotemporal substitution modeling, examination of joint associations for sitting and PA, and benefits of breaks in sitting time. Overall, the scientific evidence supports public health recommendations that encourage adults to limit their sedentary time in order to improve their cardiovascular health.
Reimagining Ubuntu in schools: A perspective from two primary school leaders in the Democratic Republic of Congo
Authors: Elonga Mboyo Jean Pierre
Published: September 2017

Communalism, otherwise known as ‘Ubuntu’ in African literature, has come to signify the philosophical and ethical thought capable of transforming behaviours/lives and restoring the continent’s cultural identity. This potent energy is explored in this article with a critical discussion of the conceptual, cultural and operational statuses of Ubuntu. While inhumanity across Africa has prompted some to question its viability, others – including the author of this article – see, in these testing times, an opportunity to reinvent the concept. Using narrative data from two urban primary head teachers based in Kinshasa/Democratic Republic of Congo (DRC), the article highlights unique Ubuntu operational patterns of understanding others’ needs, negotiating and prioritising needs, assessing available resources, attending to others’ needs, and raised expectations and commitment to organisational goals. This process, it is noted, can successfully take place in the context of genuine dialogue; a compromise that not only prevents ‘bogus needs’ and looks beyond limited resources, but also serves the interests of both individuals and schools.
Membership categorisation and antagonistic Twitter formulations
Authors: Housley William , Webb Helena , Edwards Adam , Procter Rob , Jirotka Marina
Published: September 2017

During the course of this article, we examine the use of membership categorisation practices by a high-profile celebrity public social media account that has been understood to generate interest, attention and controversy across the UK (and wider European) media ecology. We utilise a data set of harvested tweets gathered from a high-profile public ‘celebrity antagonist’ in order to systematically identify types of antagonistic formulation that have generated different levels of interest within the social media community and beyond. Drawing from classic ethnomethodological studies of banner headlines and other means of generating public interest and ‘making sense’, we respecify high-profile antagonistic tweets as category formulations that exhibit particular and regular membership category features that are reflexively bound to potential antagonistic readings, interest and controversy. In conclusion, we consider how such formulations may be understood to represent resources that constitute ignition points within antagonistic flows of communication and information that can be metaphorically understood as ‘digital wildfires’.
Group B Streptococcus tricuspid valve endocarditis with subsequent septic embolization to the pulmonary artery: A case report following elective abortion
Authors: Piedimonte Sabrina , Almohammadi Mohammad , Lee Todd C
Published: September 2017

Background

Tricuspid valve endocarditis caused by Group B streptococcus is a rare clinical entity with poor prognosis and has been previously reported following gynecologic procedures.

Case summary

We report a case of an 18-year-old female diagnosed with Group B streptococcus tricuspid valve endocarditis with septic emboli following an elective therapeutic abortion. After six weeks of treatment with ceftriaxone, she returned with recurrent symptoms and was found to have embolized a sizable vegetation to the pulmonary artery with probable lung infarction. She underwent surgical embolectomy and was treated with antibiotics and anticoagulation and was subsequently discharged in stable condition.

Conclusion

Group B streptococcus endocarditis is a serious complication of gynecologic procedures. The role of preoperative antibiotics, postoperative clinical suspicion of endocarditis based on respiratory symptoms and a multidisciplinary approach may lead to enhanced patient outcomes.
