Dizziness in the Outpatient Care Setting
Authors: Fife Terry D. 
Published: April 2017

ABSTRACT

Purpose of Review: This article summarizes an approach to evaluating dizziness for the general neurologist and reviews common and important causes of dizziness and vertigo.

Recent Findings: Improved methods of diagnosing patients with vertigo and dizziness have been evolving, including additional diagnostic criteria and characterization of some common conditions that cause dizziness (eg, vestibular migraine, benign paroxysmal positional vertigo, chronic subjective dizziness). Other uncommon causes of dizziness (eg, superior canal dehiscence syndrome, episodic ataxia type 2) have also been better clarified. Distinguishing between central and peripheral causes of vertigo can be accomplished reliably through history and examination, but imaging techniques have further added to accuracy. What has not changed is the necessity of obtaining a basic history of the patient’s symptoms to narrow the list of possible causes.

Summary: Dizziness and vertigo are extremely common symptoms that also affect function at home and at work. Improvements in the diagnosis and management of the syndromes that cause dizziness and vertigo will enhance patient care and cost efficiencies in a health care system with limited resources. Clinicians who evaluate patients with dizziness will serve their patient population well by continuing to manage patients with well-focused workup and attentive care.
Practical Considerations in Addressing Physician Burnout
Authors: Deb Anindita 
Published: April 2017

ABSTRACT
Physician burnout is an epidemic impacting patient care, career satisfaction, and physician health and well-being. Symptoms may result in potentially damaging consequences for physicians’ professional and personal lives. Neurologists are experiencing burnout at higher rates than most medical and surgical specialties. Empowering physicians to identify symptoms of burnout and engage with their organization to reduce triggers will lead to healthier physician-organization and physician-patient relationships. It is imperative that the medical community continue to raise awareness, recognize symptoms early, and provide techniques and resources to address physician burnout.
In vivomodels in breast cancer research: progress, challenges and future directions

Published: April 2017

ABSTRACTResearch using animal model systems has been instrumental in delivering improved therapies for breast cancer, as well as in generating new insights into the mechanisms that underpin development of the disease. A large number of different models are now available, reflecting different types and stages of the disease; choosing which one to use depends on the specific research question(s) to be investigated. Based on presentations and discussions from leading experts who attended a recent workshop focused on in vivo models of breast cancer, this article provides a perspective on the many varied uses of these models in breast cancer research, their strengths, associated challenges and future directions. Among the questions discussed were: how well do models represent the different stages of human disease; how can we model the involvement of the human immune system and microenvironment in breast cancer; what are the appropriate models of metastatic disease; can we use models to carry out preclinical drug trials and identify pathways responsible for drug resistance; and what are the limitations of patient-derived xenograft models? We briefly outline the areas where the existing breast cancer models require improvement in light of the increased understanding of the disease process, reflecting the drive towards more personalised therapies and identification of mechanisms of drug resistance.
It Is Not My Place! Psychological Standing and Men’s Voice and Participation in Gender-Parity Initiatives
Authors: Sherf Elad N. , Tangirala Subrahmaniam , Weber Katy Connealy 
Published: April 2017

Attempts to improve gender parity at workplaces are more effective when organizations mobilize their entire workforce, including men, to participate (i.e., speak up with ideas, volunteer, or serve as champions) in gender-parity initiatives. Yet, frequently, men are hesitant to participate in such initiatives. We explicate one reason for such hesitation on the part of men and suggest ways organizations can address this challenge. Using four studies (correlational as well as experimental), we demonstrate that men experience lower psychological standing (i.e., a subjective judgment of legitimacy to perform an action) with respect to gender-parity initiatives that leads them to participate less in such initiatives. We explain how psychological standing provides a complementary explanation to the current narrative in the literature suggesting that men’s poor participation results from sexist or discriminatory attitudes toward gender parity. We also establish that psychological standing influences participation over and above efficacy, instrumentality, and psychological safety and highlight how organizations can increase men’s participation by providing them with psychological standing when soliciting their participation in gender-parity initiatives. We discuss the implications of our findings for the literatures on gender parity, change management, and employee voice and participation.

Objective: The influence of proteins on the efficacy of antiseptic solutions has been rarely investigated even though exudate can contain high levels of protien. The aim of this study was to analyse the antibacterial efficacy of commonly used solutions in the presence of albumin protein. Method: Using Staphylococcus aureus in a standardised quantitative suspension assay, the antibacterial effects of poly (1-(2-oxo-1-pyrrolidinyl) ethylene)-iodine (PVP-I) and octenidin-dihydrochloride/phenoxyethanol (OCT/PE) were analysed in the presence of 0–3% bovine serum albumin (BSA). These were compared with previous results obtained with polyhexamethylene biguanide hydrochloride (PHMB). Results: Presence of albumin caused a significant (p<0.001) decrease in antibacterial effect in the analysed solutions. The concentrations of albumin that provoked highly significant decreases in the bacterial reduction factors of the study agents were: 0.01875 % for PVP-I, followed by 0.75 % for OCT/PE. After addition of 3 % albumin, adequate antimicrobial effects were ensured for titrations to 5 % PVP-I and 8 % OCT/PE. As we could show before, it is not possible to titrate PHMB in order to assure adequate potency. Conclusion: This study demonstrates that albumin induces a significant decrease of the antibacterial potency of the analysed solutions.

Published: April 2017

AbstractBACKGROUNDMyocardial infarction is diagnosed when biomarkers of cardiac necrosis exceed the 99th centile, although guidelines advocate even lower concentrations for early rule-out. We examined how many myocytes and how much myocardium these concentrations represent. We also examined if dietary troponin can confound the rule-out algorithm.METHODSIndividual rat cardiac myocytes, rat myocardium, ovine myocardium, or human myocardium were spiked into 400-μL aliquots of human serum. Blood was drawn from a volunteer after ingestion of ovine myocardium. High-sensitivity assays were used to measure cardiac troponin T (cTnT; Roche, Elecsys), cTnI (Abbott, Architect), and cardiac myosin-binding protein C (cMyC; EMD Millipore, Erenna®).RESULTSThe cMyC assay could only detect the human protein. For each rat cardiac myocyte added to 400 μL of human serum, cTnT and cTnI increased by 19.0 ng/L (95% CI, 16.8–21.2) and 18.9 ng/L (95% CI, 14.7–23.1), respectively. Under identical conditions cTnT, cTnI, and cMyC increased by 3.9 ng/L (95% CI, 3.6–4.3), 4.3 ng/L (95% CI, 3.8–4.7), and 41.0 ng/L (95% CI, 38.0–44.0) per μg of human myocardium. There was no detectable change in cTnI or cTnT concentration after ingestion of sufficient ovine myocardium to increase cTnT and cTnI to approximately 1 × 108 times their lower limits of quantification.CONCLUSIONSBased on pragmatic assumptions regarding cTn and cMyC release efficiency, circulating species, and volume of distribution, 99th centile concentrations may be exceeded by necrosis of 40 mg of myocardium. This volume is much too small to detect by noninvasive imaging.
Best laid plans: Research design and the field in a study of crafts in the Hampi region
Authors: Rajangam Krupa 
Published: April 2017

Abstract
The article engages with debates on the contemporary practice of ‘traditional’ regional Indian crafts and the disciplinary position of craft at a time when the roles traditionally assigned to academia, patrons (industry and craft non-governmental organizations [NGOs]) and craftspeople are in flux. The author takes the reader through a self-reflexive journey of unlearning based on her experiences as project researcher on an initiative to document traditional crafts in and around the Hampi World Heritage site. What began as an ‘objective’ attempt to present a comprehensive field-based project to document the living craft traditions of a region transformed into a discussion on the politics of research. The example of the Hampi project made it clear to the author that knowledge production is dialogic. ‘Field’, ‘place’ and ‘community’, whether project committee, general public or craftspeople (so-called objects of enquiry), can and do influence the parameters of research design. And this understanding leads to an acceptance on her part that, in turn, ‘researchers’ can only impact the field in a limited way. Consequently, a more useful role for herself and other communities, including craft NGOs, might be that of giving voice to the voiceless, in this instance, craftspeople. More significantly that the views and concerns of craftspeople do matter irrespective of whether they are in accord with the views of individuals, groups or communities that seek to support them, whether craft industry, patrons or researchers.
To collect – or not: Sir Roy Strong CH and his wardrobe
Authors: Whyman Ben 
Published: April 2017

Abstract
The biography of objects has been explored in my recent research into three men’s wardrobes stored in the collections of the Victoria and Albert Museum, London, and Fashion Museum, Bath. The aim has been to better understand how the materiality and biography of clothing, and the individual process of drawing together these ‘collections’ of material artefacts, can augment the life-story of these men’s lives. One of the subjects, Sir Roy Strong, will be used as a case study for this article. I set Strong’s life in context, and explore the notion of the biography of the object through a number of his garments. I explore notions of collecting, intentions (or lack of) behind purposeful acquisition of a group of objects like clothing, and the act of donating to a museum. In summary, I consider how the act of constructing the ‘life-story’ of fashion objects might influence the curatorial interpretations of these collections.
A brief historical overview of the first major menswear exhibition in the United States – Adam in the Looking Glass at the Metropolitan Museum of Art, New York, 1950
Authors: Maglio Diane 
Published: April 2017

Abstract
Adam in the Looking Glass was the first exclusively menswear exhibition in America. The Costume Institute of the Metropolitan Museum of Art, under the direction of Polaire Weissman, displayed more than 600 years of men’s finery arranged among paintings, decorative arts and furniture. The display techniques included garments in glass cases, dressed figures arranged in tableaux, and retail store mannequins dressed in menswear of the future. Twelve American womenswear designers were invited to create, for display in the exhibition, garments they proposed as tomorrow’s menswear. This article provides a brief historical overview of Adam in the Looking Glass which ran from 30 January 1950 to 30 July 1950.
‘There are no people in these photographs’: Human scarcity, the Sierra Club aesthetic, and the politics of presence
Authors: Blower Nicholas 
Published: April 2017

Abstract
The 1960s saw Californian environmental group the Sierra Club attempt to aestheticize conservation politics through an ambitious photographic publishing programme. Praised within the decade, prominent environmental organization leaders credited the initiative for increasing the ranks of conservation groups, catalysing public sympathy for the American wilds, and popularizing the idea of ecology. Yet critics contended that the programme created and popularized a landscape aesthetic predicated on human absence. In doing so, the Sierra Club was seen to obscure urban, class- and race-based environmental problems and help entrench a vision of nature that was separate, fantastical and elitist. In an attempt to communicate how such publications constructed nature, other studies have discounted the club’s own debates about human presence in their publishing content. This article places ideological debates about the inclusion of people within conservation photography in centre frame. It explores how the role of human presence in late 1960s conservation photography was simultaneously connected to a nostalgic desire for the return to pre-war preservationist practice and – somewhat paradoxically – to the emergent, broadened agenda of environmentalism. Furthermore, it connects disputes over presence to growing concerns about the public image of American environmentalism.
Experimental Diplomacy: Art and International Cultural Relations at 49th Parallel
Authors: Diggon Elizabeth 
Published: April 2017

Abstract
This article focuses on 49th Parallel: Centre for Contemporary Canadian Art (1981–92), a New York City-based art gallery that was conceived as a diplomatic ‘pilot project’ by Canada’s Department of External Affairs to focus on ‘new’ and ‘experimental’ Canadian contemporary art. Drawing from policy papers, memorandums and grant applications, I examine the gallery’s conceptual framework governing three key exhibitions, particularly the assumptions informing the gallery’s deployment of contemporary art as a tool of soft power within a climate of ascendant neoliberal capitalist ideologies. These records of the gallery’s mandate and programming reveal mounting pressures to increase the presence of Canadian art in the international art scene.
Relocating Iphigénie en Tauride
Authors: Pettegree Jane 
Published: April 2017

Abstract
This article reflects upon the director’s experience of directing Gluck’s Iphigénie en Tauride with a student opera company (Byre Opera) in June 2015, and in particular, insights gained about the topical issues raised by this work. Discussion of this particular production is laid alongside reviews of other, professional productions of this piece in the same year, which reveal a range of possible reactions to the potential for Gluck’s composition to be read as reflecting contemporary anxieties and concerns. The article engages with an earlier essay by Michael Ewans in SMT 9:2, 2015, developing and qualifying suggestions made by Ewans about the classical framing of Gluck’s opera to make the work relatable for modern audiences. It concludes that the classical location is used to position a very specific and not necessarily trans-historical set of topical and political resonances; this places a gap between mimetic representation and reality that should be carefully considered by any company hoping to produce the work using a contemporary realist staging.
Using focused ethnography to understand brokering practices among international students
Authors: Lee Sherrie 
Published: April 2017

Abstract
The academic challenges of international students, particularly those with English as an additional language (EAL), have been mostly researched in the context of the formal curriculum (e.g. classroom communication styles, reading and writing skills). These challenges include inadequate English proficiency and differing educational expectations, and being isolated from the host community. However, little is understood about students’ informal academic learning outside the prescribed curriculum, in particular, their brokering practices. Brokering practices are help-seeking interactions that bridge gaps in the seekers’ knowledge and understanding of new cultural practices thus enabling them to access resources they would find difficult to do so on their own. For EAL students, these help-seeking interactions may involve getting others to translate, interpret or explain particular aspects of the host academic environment. In this research, focused ethnography is used to investigate the nature of brokering practices among ten international EAL tertiary students during their initial academic semester of fifteen weeks. Focused ethnography specifically addresses constraints in the research context (e.g. time and access to informants), as well as capitalizes on technological tools such as digital recording devices. In seeking to understand brokering interactions and relationships students have with their brokers, conventional ethnographic methods were adapted, for example, digital ethnographic methods were used instead of participant observation. Digital ethnographic methods allows a large amount of data to be recorded and reviewed, a feature of focused ethnography known as data intensity. While this form of intensity has been argued to compensate for a short period of research activity, this research suggests that another form of intensity – relational intensity – is just as important in addressing research constraints. Relational intensity refers to the researcher’s ongoing responsiveness to the needs of research participants. The article concludes that future focused ethnographic research should consider both data-related and relational forms of intensity in addressing research constraints.
MONTEIRO LOBATO E O IDEÁRIO ESCOLANOVISTA: UM MODELO DE ESCOLA NO SÍTIO DO PICA-PAU AMARELO
Authors: Gomes Machado Maria Cristina , Pacifico Martineli Laís 
Published: April 2017

O estudo mostra que, com base na obra literária infantil de Monteiro Lobato (1882-1948), o autor dialogava e compartilhava com os pressupostos teórico-metodológicos do ideário escolanovista. Sua aproximação ficou expressa nos livros de literatura destinados às crianças, produzidos na primeira metade do século XX, momento em que esse movimento ganhou repercussão no país. Fundamentamos essa proposição discorrendo sobre o contato estabelecido por Monteiro Lobato com os pressupostos teóricos dessa teoria, bem como mostramos em Serões de Dona Benta, do ano de 1935, como a prática educativa do “Sítio do Pica-Pau Amarelo” se apropria dos modelos de educação propostos pela Escola Nova. Observamos que a educação desempenhava importante papel na formação moral e intelectual das crianças brasileiras, devido à necessidade de preparar trabalhadores às indústrias e os cidadãos à República. Para garantia dessa formação era necessário um outro modelo pedagógico. Monteiro Lobato teve contato com a nova corrente pedagógica quando publicou artigos que divulgavam essa corrente na Revista do Brasil, com a leitura de livros de autores renovadores e pela amizade mantida com educadores brasileiros ligados à corrente, como Anísio Teixeira. Notamos que Lobato compartilhava dos ideais da Escola Nova pela leitura de seus livros infantis, ao projetar uma escola em que a criança (personagens) participa ativamente do seu processo de aprendizagem, livre para descobrir seus interesses e aprofundá-los quando desejasse. Assim, caberia à professora (Dona Benta) fornecer os meios necessários para que elas pudessem aprender por meio de brincadeiras, ativando a imaginação. Para tanto, os conteúdos científicos se tornariam essenciais à sua formação, a aprendizagem se iniciava pela experimentação e observação por meio dos cinco sentidos e daquilo que a criança vivenciava no seu dia a dia, nesse processo o material escolar tornava-se uma ferramenta imprescindível para a aprendizagem.

O fornecimento de água potável é o maior desafio das comunidades rurais da região semiárida do Brasil, que são caracterizadas pela escassez de recursos hídricos apropriados para consumo humano. Em uma tendência observada há alguns anos, os Governos Federal e Estadual têm buscado instalar equipamentos de dessalinização das águas salobras subterrâneas para a geração de água doce para o abastecimento de comunidades distantes dos centros urbanos. Desta forma, o objetivo deste trabalho foi avaliar a qualidade das águas oriundas do processo de dessalinização de poços em comunidades rurais do oeste potiguar e seus riscos quanto ao uso na irrigação. A pesquisa foi realizada no período de 2013 e 2014 e, inicialmente, foram identificadas as comunidades abastecidas com as unidades de captação e tratamento de água por dessalinização, através de um levantamento cadastral. Para isto, foram realizadas quatro campanhas de coletas em diferentes períodos do ano para avaliação da qualidade das águas potável do tratamento por osmose reversa, poço e rejeito salino, dentro de cada período. Foram analisados parâmetros físico-químicos das águas para fins de irrigação. As águas foram classificadas quanto ao uso na irrigação; aos riscos de problemas de infiltração no solo causados pela sodicidade da água e toxicidade em plantas. As estações de tratamento de água por osmose reversa nas comunidades rurais monitoradas produziram uma água dessalinizada com concentrações baixas de sais, com 68% do total das amostras na classe de classificação C1S1; 25% na classe C2S1 e; apenas 7% na classe C3S1. Com relação ao rejeito gerado, 93% das amostras de água de rejeito se classificaram como C3 ou C4 nos quatro períodos de coleta, ou seja, águas de alto ou extremamente alto risco de salinização.
Critical news reading with Twitter? Exploring data-mining practices and their impact on societal discourse
Authors: Verbeke Mathias , Berendt Bettina , d’Haenens Leen , Opgenhaffen Michaël 
Published: April 2017

AbstractThis article shows that the collaboration between social science and computer science scholars proves fruitful in enhancing conceptual and methodological innovation in research appropriate for the digital world. It presents arguments for ways in which a multi-disciplinary approach can strengthen media studies and nnovatively advance both research breadth and depth. To illustrate this interesting connection of both disciplines, we present the example analysis of large data from Twitter and discuss this analysis in a communication science research environment. We propose TwiNeR, a software tool that analyzes tweet content using an advanced language modeling approach for classifying tweets into five prototypical messages referring to ‘activities’ related to news and news sources in the Twitter network (i.e., source-fed article, user-fed article, content spread by user, other source content, other user content).
