Job satisfaction among mental healthcare professionals: The respective contributions of professional characteristics, team attributes, team processes, and team emergent states
Authors: Fleury Marie-Josée , Grenier Guy , Bamvita Jean-Marie 
Published: December 2017

Objectives: The aim of this study was to determine the respective contribution of professional characteristics, team attributes, team processes, and team emergent states on the job satisfaction of 315 mental health professionals from Quebec (Canada). Methods: Job satisfaction was measured with the Job Satisfaction Survey. Independent variables were organized into four categories according to a conceptual framework inspired from the Input-Mediator-Outcomes-Input Model. The contribution of each category of variables was assessed using hierarchical regression analysis. Results: Variations in job satisfaction were mostly explained by team processes, with minimal contribution from the other three categories. Among the six variables significantly associated with job satisfaction in the final model, four were team processes: stronger team support, less team conflict, deeper involvement in the decision-making process, and more team collaboration. Job satisfaction was also associated with nursing and, marginally, male gender (professional characteristics) as well as with a stronger affective commitment toward the team (team emergent states). Discussion and Conclusion: Results confirm the importance for health managers of offering adequate support to mental health professionals, and creating an environment favorable to collaboration and decision-sharing, and likely to reduce conflicts between team members.
Atraumatic bilateral rupture of the peroneus brevis tendon in recreational sport: A case report
Authors: Scheidegger Patric , Weisskopf Lukas , Hirschmüller Anja 
Published: December 2017

Issue: Lower extremity tendon injuries often occur in physically active individuals. Most ruptures not involving great force are diagnosed in patients presenting underlying tendon degenerations. This also applies to patients taking medications because of a disease. We have observed several cases of bilateral Achilles tendon ruptures in patients who have been taking cortisone for a long period. We treated a healthy colleague (neurologist) in our clinic who sustained ruptures of the Achilles tendon on the left side (2012) and the peroneus brevis tendon on left side (2015) and right side (2016) after minimal traumata. Aim of this report is to provide a systematic review of this case and a literature review of similar cases, as few such cases have been published. Methods: We reviewed and analysed this patient’s records containing the sport-specific anamnesis, pre-existing condition, anamnesis of medications and therapy. The three injuries were magnetic resonance imaging–proven. Furthermore, the tendon’s condition was examined histologically in the context of the operative treatment through lace technique of the Achilles tendon and transfer of the peroneus brevis to the peroneus longus. We also researched the literature for bilateral ruptures of the peroneal tendons. Results and conclusion: The anamnesis confirmed no underlying disease. The patient took a macrolide antibiotic about half a year prior to the first peroneal injury for an otitis media. He denied having taken any other antibiotics, especially no quinolone antibiotics. However, the patient reported cortisone intake for 2 days some months before the second peroneal injury to treat an allergic reaction. That involved no local cortisone infiltration in the lower extremity. He underwent surgery within the first 2 weeks after each trauma. Each time, postoperative follow-ups revealed a good healing process. Three months after each operation, the patient was free of complaints. Axibal and Anderson described a patient with bilateral peroneus longus and peroneus brevis ruptures, as well as an Achilles tendon rupture on the left side plus tendinopathy of the Achilles tendon on the right side of uncertain aetiology. We detected additional similar cases in patients who had taken medications, especially cortisone and levofloxacine. Further research should be conducted to clarify other risk factors to help prevent such injuries.
Retrospective Analysis of the Accuracy of Ultrasound-Guided Magnetic Resonance Arthrogram Injections of the Hip in the Office Setting
Authors: Jernick Michael , Walker Gallego Edward , Nuzzo Michael 
Published: December 2017

Background: Ultrasound (US)–guided intra-articular hip injections have been proposed in the literature to be accurate, reliable, and safe alternatives to fluoroscopy-guided injections. Purpose: To evaluate the accuracy of US-guided magnetic resonance (MR) arthrogram injections of the hip performed in the office setting by a single orthopaedic surgeon and elucidate the potential effects that patient age, sex, and body mass index (BMI) have on contrast placement. Study Design: Case series; Level of evidence, 4. Methods: From a review of the senior author’s office database, 89 patients (101 hips) who had US-guided MR arthrogram injections performed between December 2014 and June 2016 were identified. Official radiology reports were evaluated to determine whether extra-articular contrast was noted. Patient variables, including BMI, age, and sex, were evaluated between patients who had inappropriately placed contrast and those who did not. Results: Of the 101 hip injections, there were 6 cases that demonstrated inadequate contrast placement within the joint, likely secondary to extravasation or incorrect placement; however, an MR arthrogram was adequately interpreted in all cases. There were no significant differences noted between those with appropriate versus inappropriate contrast placement when evaluating BMI ( P = .57), age ( P = .33), or sex ( P = .67), and neither group had an adverse event. Conclusion: US-guided injections are safe and accurate alternatives to fluoroscopy-guided injections in the office setting, with 94% accuracy. Furthermore, BMI, age, and sex did not play a statistically significant role among patients with inappropriately placed contrast.
The People, the Megaliths of Cherrapunjee
Authors: Sharma Sukanya 
Published: December 2017

The megaliths of Cherrapunjee are part of a prehistoric cultural tradition which is intricately woven with the sociocultural life of the Khasis and Jaintias. But material changes in the nature of society and the economy in the latter half of the twentieth century have resulted in new identity formations in Cherrapunjee and this has undermined some of the presumed certainties of cultural identity. The study documents local community attitudes regarding the megaliths and how the community accessed, interacted and used the sites today. A framework for managing archaeological heritage by integrating global and local conservation approaches in Cherrapunjee was developed.

Abstract

Context
Weaver syndrome is characterized by tall stature, advanced bone age, characteristic facies, and variable intellectual disability. It is caused by heterozygous mutations in enhancer of zeste homolog 2 (EZH2), a histone methyltransferase responsible for histone H3 at lysine 27 (H3K27) trimethylation. However, no early truncating mutations have been identified, suggesting that null mutations do not cause Weaver syndrome.

Objective
To test alternative hypotheses that EZH2 variants found in Weaver syndrome cause either a gain of function or a partial loss of function.

Design
Exome sequencing was performed in a boy with tall stature, advanced bone age, and mild dysmorphic features. Mutant or wild-type EZH2 protein was expressed in mouse growth plate chondrocytes with or without endogenous EZH2, and enzymatic activity was measured. A mouse model was generated, and histone methylation was assessed in heterozygous and homozygous embryos.

Results
A de novo missense EZH2 mutation [c.1876G&gt;A (p.Val626Met)] was identified in the proband. When expressed in growth plate chondrocytes, the mutant protein showed decreased histone methyltransferase activity. A mouse model carrying this EZH2 mutation was generated using CRISPR/Cas9. Homozygotes showed perinatal lethality, whereas heterozygotes were viable, fertile, and showed mild overgrowth. Both homozygous and heterozygous embryos showed decreased H3K27 methylation.

Conclusion
We generated a mouse model with the same mutation as our patient, found that it recapitulates the Weaver overgrowth phenotype, and demonstrated that EZH2 mutations found in Weaver syndrome cause a partial loss of function.

Abstract. Residual soil water after harvest and prior to planting was measured to a depth of 2.4 m with neutron attenuation techniques for approximately 45 irrigated corn and 45 dryland wheat fields annually from 2010 through 2012 in the western one-third of Kansas. The sampling locations were in three-county transects in northwest, west central and southwest Kansas with generally five fields for each crop type for each county. Residual plant available soil water (PASW) in corn fields was generally much greater than in wheat fields (150%-160% greater) for any given sampling period illustrating the residual influence of irrigation. Although weather conditions varied between regions and years there was not a strong effect on PASW in irrigated corn fields but there was an effect in dryland wheat fields. Annual differences in fall irrigated corn PASW for the 21 individual fields that were available for sampling in all three years varied less than 50 mm/2.4 m soil profile implying considerable stability in an individual producer’s response (irrigation management and irrigation system capacity) to changing weather conditions as evidenced by the similar year-to-year PASW values. Drought conditions existed for much of the total period (fall 2010 through fall 2012) in southwest Kansas, yet the irrigated corn PASW was still relatively high (PASW value at approximately 62% of water stored at field capacity in a 2.4 m profile). So, the presence of drought may not be a good indicator of the amounts of residual soil water producers are leaving after irrigated corn harvest. Although differences in irrigated corn PASW varied greatly among producers (183% to 722% within a region), there were much smaller differences between regions and years with a variation from 8% to 22%. Irrigation system capacity (flowrate/area) had very little effect on residual fall PASW in the corn fields possibly indicating that producers with deficit capacity are pumping earlier and later into the season to help mitigate their lower irrigation capacity. Irrigated corn grain yields began to plateau when PASW reached a value of approximately 200 mm/2.4 m profile which would represent a water storage of approximately 56% of field capacity. The residual PASW in irrigated corn fields decreased about 1 mm for each 2 mm decrease in irrigation and cropping season precipitation illustrating the difficulties that can arise in managing for a target residual PASW. These results suggest that producers should be scheduling irrigation with science-based methods, rather than habits and previous experiences.

Knowledge brokers or relationship brokers? The role of an embedded knowledge mobilisation team
Authors: Wye Lesley , Cramer Helen , Carey Jude , Anthwal Rachel , Rooney James , Robinson Rebecca , Beckett Kate , Farr Michelle , le May Andrée , Baxter Helen 
Published: December 2017

Aim:
Policymaking decisions are often uninformed by research and research is rarely influenced by policymakers. To bridge this ‘know-do’ gap, a boundary-spanning knowledge mobilisation (KM) team was created by embedding researchers-in-residence and local policymakers into each other’s organisations. Through increasing the two-way flow of knowledge via social contact, KM team members fostered collaborations and the sharing of ‘mindlines’, aiming to generate more relevant research bids and research-informed decision-making. This paper describes the activities of the KM team, types of knowledge and how that knowledge was exchanged to influence mindlines.

Discussion:
KM team activities were classified into: relational, dissemination, transferable skills, evaluation, research and awareness raising. Knowledge available included: profession-specific (for example, research methods, healthcare landscape), insider (for example, relational, organisation and experiential) and KM theory and practice. KM team members brokered relationships through conversations interweaving different types of knowledge, particularly organisational and relational. Academics were interested in policymakers’ knowledge of healthcare policy and the commissioning landscape. More than research results, policymakers valued researchers’ methodological knowledge. Both groups appreciated each other as ‘critical friends’.

Conclusion:
To increase research impact, ‘expertise into practice’ could be leveraged, specifically researchers’ critical thinking and research methodology skills. As policymakers’ expertise into practice also bridges the know-do gap, future impact models could focus less on evidence into practice and more on fostering this mutual flow of expertise. Embedded knowledge brokers from the two communities working in teams can influence the mindlines of both. These ambassadors can create improvements in ‘inter-cultural competence’ to draw academia and policymaking closer.
Moon: A sensuous scholarship of the art of costume breakdown in film
Authors: Parry Harriet 
Published: December 2017

Abstract
Cloth has a particular relationship with the human body. It is always in contact with, or imagined to be in contact with, the skin, our largest sense organ. Cloth is our interface with the outside world, and the way in which we cover that interface has meaning. The important relationship that we have with cloth to protect and augment our bodies performs as a prosthesis of touch that, in its everydayness, offers a constant opportunity for expression and fetishization within the various discourses of identity in art, fashion and lifestyle. This article aims to explore the way in which cloth as costume in the medium of film, having been ‘broken down’ to naturalize the piece to its setting, stimulates an embodied relationship between the audience, the actor and the film itself. Following Laura Marks and her theories on visual haptics, the piece is a sensuous scholarship of an-often overlooked and under-researched textile art whose effect, the article argues, is that of reinstating the ‘aura’ that Walter Benjamin stated is lost by the mechanical intervention of the movie camera.
Designing a system for Online Orchestra: Microphone evaluation and cost-benefit analysis
Authors: Geelhoed Erik , Prior David , Rofe Michael 
Published: December 2017

Abstract
Online Orchestra is a telematic performance project that aimed to enable young and amateur musicians to make music online. Part of the aim of the project was to assess the extent to which specialist equipment is needed in order to enable a high-quality musical experience in a telematic environment. This article reports a microphone evaluation study in which untrained participants were asked to assess ten characteristics of quality in five samples, each recorded using different microphone configurations. Results show that participants rated DPA VO4099 clip-on microphones best, but that a stereo pair of Sure SM57s – which are over ten times cheaper – was rated a close second. Multidimensional scaling also shows that SM57s had the highest similarity to all other microphone configurations, suggesting they are a good alternative to costlier solutions.

Abstract
This visual essay introduces and describes an IOS app that is currently in development. The app is based on an ongoing project Pillflowers (2004–present), an aesthetic response to the prevalent use of pharmaceuticals in North American society. Pills and tablets make up the petals of flowers that create 200 mandala-like designs. The essay details the five functions of the app that are either created or in process – grow, gather, play, dream and gift. An analysis and associated images for each function round out the text.
On locally essentially bounded divergence measure fields and sets of locally finite perimeter
Authors: Comi Giovanni E. , Payne Kevin R. 
Published: December 2017

AbstractChen, Torres and Ziemer ([9], 2009) proved the validity of generalized Gauss–Green formulas and obtained the existence of interior and exterior normal traces for essentially bounded divergence measure fields on sets of finite perimeter using an approximation theory through sets with a smooth boundary. However, it is known that the proof of a crucial approximation lemma contained a gap. Taking inspiration from a previous work of Chen and Torres ([7], 2005) and exploiting ideas of Vol’pert ([29], 1985) for essentially bounded fields with components of bounded variation, we present here a direct proof of generalized Gauss–Green formulas for essentially bounded divergence measure fields on sets of finite perimeter which includes the existence and essential boundedness of the normal traces. Our approach appears to be simpler since it does not require any special approximation theory for the domains and it relies only on the Leibniz rule for divergence measure fields. This freedom allows one to localize the constructions and to derive more general statements in a natural way.
Quantization of energy and weakly turbulent profiles of solutions to some damped second-order evolution equations
Authors: Ghisi Marina , Gobbino Massimo , Haraux Alain 
Published: December 2017

Abstract
We consider a second-order equation with a linear “elastic” part and a nonlinear damping term depending on a power of the norm of the velocity.
We investigate the asymptotic behavior of solutions, after rescaling them suitably in order to take into account the decay rate and bound their energy away from zero.
We find a rather unexpected dichotomy phenomenon.
Solutions with finitely many Fourier components are asymptotic to solutions of the linearized equation without damping and exhibit some sort of equipartition of the total energy among the components.
Solutions with infinitely many Fourier components tend to zero weakly but not strongly.
We show also that the limit of the energy of the solutions depends only on the number of their Fourier components.
The proof of our results is inspired by the analysis of a simplified model, which we devise through an averaging procedure, and whose solutions exhibit the same asymptotic properties as the solutions to the original equation.

Published: December 2017

Abstract
The paper presents a neutronic analysis of the battery-type 20 MWth high-temperature gas cooled reactor. The developed reactor model is based on the publicly available data being an ‘early design’ variant of the U-battery. The investigated core is a battery type small modular reactor, graphite moderated, uranium fueled, prismatic, helium cooled high-temperature gas cooled reactor with graphite reflector. The two core alternative designs were investigated. The first has a central reflector and 30×4 prismatic fuel blocks and the second has no central reflector and 37×4 blocks. The SERPENT Monte Carlo reactor physics computer code, with ENDF and JEFF nuclear data libraries, was applied. Several nuclear design static criticality calculations were performed and compared with available reference results. The analysis covered the single assembly models and full core simulations for two geometry models: homogenous and heterogenous (explicit). A sensitivity analysis of the reflector graphite density was performed. An acceptable agreement between calculations and reference design was obtained. All calculations were performed for the fresh core state.

Published: December 2017

Abstract
Objectives. The objective of this study was to evaluate the effect of vitamin E on the oxidative stress parameters and antioxidant defense enzymes in the heart and aorta of 6-n-propylthiouracil (PTU)-induced hypothyroid rats. Methods. The animals were divided into 4 experimental groups: Group 1 (Euthyroid) received tap water, Group 2 (Hypothyroid) received 0.05 % of PTU in dissolved in their drinking water, Group 3 (PTU+Vit E) hypothyroid rats treated with vitamin E, and Group 4 (Euthyroid+Vit E). Vitamin E was injected daily (20 mg/kg) to groups 3 and 4 via daily gavage for 6 weeks. Malondialdehyde (MDA) levels, total thiol levels, and the activities of Cu, Zn-superoxide dismutase (SOD) and catalase (CAT) were evaluated in the aortic and cardiac tissues. Results. A significant decrease of thyroxine (T4) serum levels confirmed hypothyroidism in rats, which received PTU. The MDA level increased and total thiol level decreased in the hypothyroid group compared to control group (p<0.001). Th e activities of SOD and CAT significantly decreased in the hypothyroid rats in comparison to the control. Vitamin E treatment resulted in increased levels of total thiol, SOD, and CAT within aortic and cardiac tissues and decreased levels of MDA in comparison with the hypothyroid group (p<0.01−p<0.001). Conclusions. PTU-induced hypothyroidism resulted in oxidative stress. Chronic administration of vitamin E to hypothyroid rats decreased the oxidative stress markers in the aortic and cardiac tissues.
