The impact of an obstetrician-led, labor ward critical care unit: A prospective comparison of outcomes before and after establishment
Authors: Langenegger Eduard J , Hall DR , Mattheyse F , Harvey J
Published: April 2019

Objective

To investigate the outcomes of critically ill obstetric patients managed in a obstetric critical care unit in South Africa.

Methods

Patients with severe maternal morbidity managed in the labor ward of Tygerberg Hospital were studied over three months before the establishment of the obstetrician-led obstetric critical care unit. One year later, patients managed in the obstetric critical care unit were studied using the same methods. The primary outcome measures were maternal morbidity and mortality.

Results

In the before-obstetric critical care unit prospective audit 63 patients met criteria for obstetric critical care. During the second period 60 patients were admitted to the obstetric critical care unit. There were no significant differences between the groups in baseline characteristics, admission indications or Acute Physiology and Chronic Health Evaluation scores. Continuous positive airway pressure ( p < 0.01) was utilized more in the second group. Seven deaths occurred in the first, but none in the second group ( p = 0.01).

Conclusion

The establishment of an obstetrician-led obstetric critical care unit facilitated a decrease in maternal mortality. Trial registration: Not applicable.
Millennial Attitudes Toward Online and Traditional Training Methods: The Role of Training Utility and Satisfaction
Authors: Bernardes Renata F. , Guzzo Renata F. , Madera Juan M.
Published: April 2019

Because the millennial generation is the largest generation in the U.S. labor force and is the most computer-literate generation, many organizations are investing in online methods for their training. From a recruitment perspective, applicants can use training information to form attitudes about an organization, such as their attraction. Yet, research has not examined whether organizational attraction is influenced by the type of training method an organization offers. Using two experiments, the purpose of the current article was to examine organizational attraction as a function of whether a training program is described as online or on-the-job, and pretraining satisfaction and perceived utility as mediators of this relationship. Study 1 used a two-group (online and on-the-job) between-subjects experimental design. Study 2 used a three-group (online, on-the-job, and combined online and on-the-job training) between-subjects experimental design to replicate Study 1 and add an additional condition: combining online and on-the-job methods. Participants were instructed to read a hotel’s recruitment information for a front office position and evaluate the hotel assuming the role of an applicant. Participants had higher organizational attraction when training was described as on-the-job training than as online training. The effect of training method on organizational attraction was mediated by training satisfaction and utility. The most important theoretical contribution of the current studies is that the results contradict the general stereotypes and expectations of millennials. The results contribute to understanding how prospective applicants use organizational characteristics, such as the type of training they offer, to form attitudes, such as organizational attraction.
Subcomponents of Right-Wing Authoritarianism Differentially Predict Attitudes Toward Obeying Authorities
Authors: Mallinas Stephanie R. , Crawford Jarret T. , Frimer Jeremy A.
Published: April 2019

Previous theory and research has suggested that right-wing authoritarianism (RWA) is a unitary construct related to attitudes regarding obedience to authority. Recently, scholars have suggested that RWA is multidimensional. To adjudicate these competing notions, we test whether the associations between RWA components and moral attitudes regarding obedience differ depending on the ideology of the authority. Across three studies and an integrative data analysis, we found that the RWA component capturing obedience to and respect for authorities (i.e., submission) related to judgments that it is moral to obey all authorities, and perhaps also nonauthorities, regardless of the targets’ political ideologies. In contrast, the RWA component capturing socially conservative beliefs (i.e., traditionalism) related to judgments that it is moral to obey conservative authorities and immoral to obey liberal authorities. These results suggest that RWA is not a unitary construct and that its components differentially relate to moral judgments regarding obedience to authorities.
Matters Order: The Role of Information Order on Implicit Impression Formation
Authors: Fourakis Eva , Cone Jeremy
Published: April 2019

A classic finding in the person perception literature is that information order is an important factor in the impressions we form of others. But how does order influence the formation of implicit evaluations? In three preregistered experiments including nearly 900 participants, we find evidence for a strong primacy effect even at the implicit level. This occurred on an affect misattribution procedure (Study 1), an evaluative priming task (Study 2), and an implicit association test (Study 3). These findings suggest that, just as explicit impressions are susceptible to primacy effects, so too are implicit ones. Implications for theories of evaluative conditioning and attitudes are discussed.
Making Sure You See the Real Me: The Role of Self-Esteem in Spontaneous Self-Expansion
Authors: Slotter Erica B. , Kolarova Lyuboslava
Published: April 2019

People alter their self-concepts by incorporating attributes of close others, such as desired romantic partners, into their own identity. The current research examined self-esteem as a moderator of this spontaneous self-expansion. Two studies tested the hypothesis that when presented with a prospective romantic partner, higher self-esteem people (HSE) would self-expand to adopt positive attributes, while lower self-esteem people (LSE) would self-expand to adopt negative attributes. This tendency corresponds with people’s desire to self-verify and be seen by others in line with their own self-views, which are often negative among those lower in self-esteem. Study 1 ( n = 218) and Study 2 ( n = 234) confirmed our predictions that when motivated to increase romantic closeness to a prospective partner, self-esteem differentially predicts people’s spontaneous self-expansion to adopt positive versus negative attributes.

Published: April 2019

In this study, to compare the efficacy of minimally invasive surgery transforaminal lumbar interbody fusion (MIS-TLIF) combined with unilateral or bilateral internal fixation for the treatment of single-segment lumbar degenerative diseases, patients with single-segment lumbar degenerative diseases treated with MIS-TLIF combined with unilateral or bilateral internal fixation in Rehabilitation Center, Gansu Province Hospital from January 2014 to November 2015 were retrospectively enrolled, and the related data of 85 patients with 2-year follow-up were obtained. The patients were divided into unilateral group (40 cases) and bilateral group (45 cases) according to the method of internal fixation, and the Oswestry dysfunction index (ODI), visual analogue scale (VAS), lumbar lordosis angle, surgical segmental lordosis angle, lumbar scoliosis angle, surgical segmental scoliosis angle, lumbar lordosis index (LI), intervertebral height index (IHI), fusion rates, and serum inflammatory factors, including C-reactive protein (CRP), interleukin (IL)-6, and tumor necrosis factor alpha (TNF-α), were calculated to evaluate the efficacy of these two surgical methods. The results showed that the VAS and ODI of the two groups at 1 month, 6 months after surgery, and the last follow-up were significantly improved when compared with those before surgery ( P < 0.05). However, there were no significant differences in VAS and ODI between the two groups at preoperative, 1 month, 6 months after surgery, and the last follow-up ( P > 0.05). The lumbar lordosis and LI decreased at 1 month, 6 months, and the last follow-up ( P < 0.05), while the IHI increased when compared with that before surgery ( P < 0.05). Besides, no significant differences were observed in lumbar lordosis, LI, and IHI between the two groups at preoperative, 1 month, 6 months after surgery, and final follow-up ( P > 0.05). In addition, the fusion rates between these two groups had no significant difference ( P > 0.05). The levels of serum CRP, IL-6, and TNF-α at 12 and 24 h after operation in the two groups were higher than those before operation ( P < 0.05), but there was no significant difference in the levels of serum CRP, IL-6, and TNF-α between the two groups at 12 and 24 h after operation ( P < 0.05). In addition, none of the patients of both groups had permanent nerve injury, incision infection, and other complications. These results showed that MIS-TLIF combined with unilateral or bilateral percutaneous internal fixation technique causes less damage to the body tissues of patients with single-segment lumbar degenerative diseases, and they were considered to have similar clinical effects and imaging.
TaskMaster: A Tool for Determining When Subjects Are on Task
Authors: Permut Stephanie , Fisher Matthew , Oppenheimer Daniel M.
Published: April 2019

In this Tutorial, we introduce a tool that allows researchers to track subjects’ on- and off-task activity on Qualtrics’ online survey platform. Our TaskMaster tool uses JavaScript to create several arrayed variables representing the frequency with which subjects enter and leave an active survey window and how long they remain within a given window. We provide code and instructions that will allow researchers to both implement the TaskMaster and analyze its output. We detail several potential applications, such as in studies of persistence and cheating, and studies that require sustained attention to experimental outcomes. The TaskMaster is designed to be accessible to researchers who are comfortable designing studies in Qualtrics, but who may have limited experience using programming languages such as JavaScript.

Published: April 2019

In this work, composite nanofiber membranes were prepared by adding modified nano-sized Al2O3-particles to a polyvinylidene fluoride (PVDF) solution (17 wt %) through an electrospinning process. The Al2O3 content affected the spun membrane performance, such as hydrophilicity, bovine serum albumin (BSA) rejection rate and anti-fouling properties were examined in detail. UF (experiment with an ultrafiltration cup) experiment was used to measure how the membrane water flux changed. This test showed that the nanoparticle affect was remarkable, the pure water flux was 4635 L•m−2•h−1 in 2% Al2O3/PVDF membrane versus 3546 L•m−2•h−1 for the membrane without nanoparticles. Contact angle was used to determine the hydrophilicity change of membranes. The results demonstrate that the modified membrane hydrophilicity was enhanced dramatically the contact angle of composite membrane with 2% Al2O3 was 56.34° versus 85.64° for the pristine PVDF membrane. The roughness and surface structure were measured by atomic force microscope (AFM) and electron microscopy (SEM). There were clear fibers in SEM images and the membrane surface roughness was heightened by adding nanoparticles. The rejection rate was investigated by UV spectrophotometer and the porosity was measured using a dry-wet weight method. The spun membrane rejection rate was 95.4%. Thermo gravimetric Analysis (TGA) and Fourier transform infrared spectroscopy (FT-IR) were used to study how nano-Al2O3 particles affected the membrane structure. More importantly, the Al2O3/PVDF spun membrane displayed an outstanding anti-fouling property. To sum up, this composite spun membrane shows a remarkable efficiency in the test and could be an ideal candidate for water treatment.

Published: April 2019

Deficiency of the Nox2 (gp91phox) catalytic subunit of nicotinamide adenine dinucleotide phosphate (NADPH) oxidase is a genetic cause of X-linked chronic granulomatous disease, a condition in which patients are prone to infection resulting from the loss of oxidant production by neutrophils. Some studies have suggested a role for superoxide derived from Nox2 NADPH oxidase in platelet activation and thrombosis, but data are conflicting. Using a rigorous and comprehensive approach, we tested the hypothesis that genetic deficiency of Nox2 attenuates platelet activation and arterial thrombosis. Our study was designed to test the genotype differences within male and female mice. Using chloromethyl-dichlorodihydrofluorescein diacetate, a fluorescent dye, as well as high-performance liquid chromatography analysis with dihydroethidium as a probe to detect intracellular reactive oxygen species (ROS), we observed no genotype differences in ROS levels in platelets. Similarly, there were no genotype-dependent differences in levels of mitochondrial ROS. In addition, we did not observe any genotype-associated differences in platelet activation, adhesion, secretion, or aggregation in male or female mice. Platelets from chronic granulomatous disease patients exhibited similar adhesion and aggregation responses as platelets from healthy subjects. Susceptibility to carotid artery thrombosis in a photochemical injury model was similar in wild-type and Nox2-deficient male or female mice. Our findings indicate that Nox2 NADPH oxidase is not an essential source of platelet ROS or a mediator of platelet activation or arterial thrombosis in large vessels, such as the carotid artery.
Over- and under-diagnosis in asthma
Authors: Kavanagh Joanne , Jackson David J. , Kent Brian D.
Published: April 2019

Asthma is extremely common with a prevalence of approximately 10% in Europe. It presents with symptoms which have a broad differential diagnosis and examination can be entirely normal. There is no agreed gold standard to diagnose asthma, and the objective tests that can aid diagnosis are often poorly available to primary care physicians. There is evidence that asthma is widely misdiagnosed. Overdiagnosis leads to unnecessary treatment and a delay in making an alternative diagnosis. Underdiagnosis risks daily symptoms, (potentially serious) exacerbations and long-term airway remodelling. An agreed standardised approach to diagnosis, with inclusion of objective measurements prior to treatment, is required to reduce misdiagnosis of asthma.

Key points

Asthma presents with common respiratory symptoms and physical examination is often normal; in addition, the most widely available tests (peak flow and spirometry) can be normal unless the patient is exacerbating.

Treating asthma prior to carrying out objective tests decreases their sensitivity and can make confirmation of the diagnosis difficult.

There is no single gold standard test to diagnose asthma, and there are significant differences between the suggested algorithms in commonly used guidelines.

Both under- and over-diagnosis are widespread and lead to significant risks to patients.

Published: April 2019

Background

Triage trauma scores are utilised to determine patient disposition, interventions and prognostication in the care of trauma patients. Heart rate variability (HRV) and heart rate complexity (HRC) reflect the autonomic nervous system and are derived from electrocardiogram (ECG) analysis. In this study, we aimed to develop a model incorporating HRV and HRC, to predict the need for life-saving interventions (LSI) in trauma patients, within 24 h of emergency department presentation.

Methods

We included adult trauma patients (≥ 18 years of age) presenting at the emergency department of Singapore General Hospital between October 2014 and October 2015. We excluded patients who had non-sinus rhythms and larger proportions of artefacts and/or ectopics in ECG analysis. We obtained patient demographics, laboratory results, vital signs and outcomes from electronic health records. We conducted univariate and multivariate analyses for predictive model building.

Results

Two hundred and twenty-five patients met inclusion criteria, in which 49 patients required LSIs. The LSI group had a higher proportion of deaths (10, 20.41% vs 1, 0.57%, p < 0.001). In the LSI group, the mean of detrended fluctuation analysis (DFA)-α1 (1.24 vs 1.12, p = 0.045) and the median of DFA-α2 (1.09 vs 1.00, p = 0.027) were significantly higher. Multivariate stepwise logistic regression analysis determined that a lower Glasgow Coma Scale, a higher DFA-α1 and higher DFA-α2 were independent predictors of requiring LSIs. The area under the curve (AUC) for our model (0.75, 95% confidence interval, 0.66–0.83) was higher than other scoring systems and selected vital signs.

Conclusions

An HRV/HRC model outperforms other triage trauma scores and selected vital signs in predicting the need for LSIs but needs to be validated in larger patient populations.

Published: April 2019

The pore structure controls the formation processes of tight oil reservoirs. It is meaningful to study the characteristics and origin of the pore structure of the tight oil reservoir. We have analyzed the pore structure of the tight oil reservoir by thin sections, scanning electron microscopy, and mercury intrusion porosimetry. We analyze the origin of the pore structure based on sedimentological, diagenetic, and tectonism processes. The porosity of the tight oil reservoirs is mainly approximately 2%–10%, and the permeability is mainly from 0.01 to 0.3 mD. The pores of the lacustrine tight oil reservoir can be classified into the primary pore and the secondary pore. The main pores are matrix micropores and clay intercrystalline pores, as well as a few dissolved pores. However, the primary residual intergranular pore has almost disappeared, leading to a poor connectivity with a general size between 20 and 50 μm. The pore throat is divided into three categories (type I, type II, and type III) according to the porosity, permeability, and throat size and distribution. We determine that the pore structure of the lacustrine tight oil reservoir is related to sedimentary, diagenetic processes, and later tectonic events. The compaction and cementation are the main factors, whereas the dissolution and tectonic events have minor effects.
Investigation of gut microbiome association with inflammatory bowel disease and depression: a machine learning approach
Authors: Morell Miranda Pedro , Bertolini Francesca , Kadarmideen Haja N.
Published: April 2019

Background: Inflammatory bowel disease (IBD) is a group of chronic diseases related to inflammatory processes in the digestive tract generally associated with an immune response to an altered gut microbiome in genetically predisposed subjects. For years, both researchers and clinicians have been reporting increased rates of anxiety and depression disorders in IBD, and these disorders have also been linked to an altered microbiome. However, the underlying pathophysiological mechanisms of comorbidity are poorly understood at the gut microbiome level.

Methods: Metagenomic and metatranscriptomic data were retrieved from the Inflammatory Bowel Disease Multi-Omics Database. Samples from 70 individuals that had answered to a self-reported depression and anxiety questionnaire were selected and classified by their IBD diagnosis and their questionnaire results, creating six different groups. The cross-validation random forest algorithm was used in 90% of the individuals (training set) to retain the most important species involved in discriminating the samples without losing predictive power. The validation set that represented the remaining 10% of the samples equally distributed across the six groups was used to train a random forest using only the species selected in order to evaluate their predictive power.

Results: A total of 24 species were identified as the most informative in discriminating the 6 groups. Several of these species were frequently described in dysbiosis cases, such as species from the genus Bacteroides and Faecalibacterium prausnitzii. Despite the different compositions among the groups, no common patterns were found between samples classified as depressed. However, distinct taxonomic profiles within patients of IBD depending on their depression status were detected.

Conclusions: The machine learning approach is a promising approach for investigating the role of microbiome in IBD and depression. Abundance and functional changes in these species suggest that depression should be considered as a factor in future research on IBD.

Published: April 2019

Cutaneous tuberculosis (TB) can present in a number of ways, making it difficult to diagnose. It most commonly presents as scrofuloderma, which commonly affects the supra-clavicular region, axilla and the cervical region. All the different presentations of cutaneous TB should be known to clinicians, in order to diagnose it early. The objective of this article is to describe a case of scrofuloderma presenting with different cutaneous lesions at the same time, which were culture negative. We present a 23-year-old male with no known co-morbidities, presenting to us with fever and multiple swellings on the body. Cultures of pus and blood were negative for TB; GeneXpert detected the microorganism. Cutaneous TB, although a rare disease with wide spectrum of cutaneous lesions, should be considered in differential diagnosis of cold abscesses and nodules, especially of the head and neck region.

In this article, we will discuss gaming techniques to study species-tense forms of the Russian verb at the initial stage of teaching Russian as a foreign language. Game techniques belong to the group of interactive methods in modern education. Interest in them emerged when educational practice showed that positive changes in society could not be achieved within the framework of the traditional model of education. Game techniques contribute to the formation of foreign students communicative, linguistic and linguistic competencies, develop the ability to work in a team to defend their own opinion. Of particular relevance is the use of interactive techniques in the study of the species-temporal forms of verbs at the initial stage of teaching Russian as a foreign language. Develop and verify the effectiveness of the proposed in the article the methodology was carried out in 2016-2018, the experiential learning was conducted on the basis of the National Research Ogarev Mordovia State University. Analysis of the results of application of game methods in the study of species-tense forms of the Russian verb showed that the proposed method gave educational process more informed and fascinating character. Interactive tasks contributed to the development of communicative and linguistic competence of students and helped foreign students acquire social experience of interaction in the language environment.

Conceptual Foundations of Organizational Motivation
Authors: Пугачев В. , Pugachyev V.
Published: April 2019

The article is devoted to the development of the conceptual framework of motivational work in organization. Based on the critical analysis of the fundamental categories of motivation theories presented in modern literature, their failure to render the whole process of determination and understanding of the employees’ behavior is revealed. The necessity for using the broad concept of ‘staff motivation’ is confirmed, it allows covering the diversity of processes that encourage the particular behavior of personnel. The strengths and weaknesses of the motivational-stimulation approach to the determination of the behavior of employees that has become the dominating one in the recent years are revealed. The necessity of transition from the traditional stimulation paradigm which is inherent to industrial society to a modern integrative paradigm that meets the requirements of the information society at the digital stage of its development is confirmed. For standardization and systematization of the major categories of the motivation theory the activity approach is applied; it allows presenting all components of the motivation process in a comparable manner as the various elements and types of the ‘hard’ (past) and soft (‘alive’, present), material and ideal (spiritual) activities. The activity structure of motivational process is considered, it helps to highlight its key components and to take them into account in the practical motivational work. The need for the further development and concretization of the settings and imperatives of the integration paradigm of motivation in its relation to the organizational system of motivation is pointed out. This issue will be considered in the author’s following article ‘Integration paradigm in the study of the organizational system of motivation and motivational practices’ which is planned to be presented in the immediate issue.

A Stochastic Trust Region Algorithm Based on Careful Step Normalization
Authors: Curtis Frank E. , Scheinberg Katya , Shi Rui
Published: April 2019

An algorithm is proposed for solving stochastic and finite-sum minimization problems. Based on a trust region methodology, the algorithm employs normalized steps, at least as long as the norms of the stochastic gradient estimates are within a specified interval. The complete algorithm—which dynamically chooses whether to employ normalized steps—is proved to have convergence guarantees that are similar to those possessed by a traditional stochastic gradient approach under various sets of conditions related to the accuracy of the stochastic gradient estimates and choice of step size sequence. The results of numerical experiments where the method is employed to minimize convex and nonconvex machine learning test problems are presented. These results illustrate that the method can outperform a traditional stochastic gradient approach.

CONSERVAR O INÍCIO DE TUDO: MAPEANDO VOZES NA CENA ENUNCIATIVA CONSERVADORA
Authors: Freixo Estêvão De Carvalho
Published: April 2019

O presente trabalho consiste num esforço de mapeamento das possíveis alianças discursivas que acreditamos contribuírem para configuração do campo político conservador-liberal estabelecido hoje no Brasil. Para a realização dessa tarefa, utilizamos o conceito de formação discursiva, inaugurado nos trabalhos Foucault e posteriormente revisto nos desenvolvimentos trazidos por Michel Pêcheux, entendendo que um campo político responde a um sistema particular de coerções discursivas. Além disso, aproveitamos a translinguística bakhtiniana, e a extensão que Oswald Ducrot lhe acrescenta, a fim de desmembrar as vozes que se articulam em cada um desses sistemas discursivos, podendo assim melhor identificá-las em sua especificidade. Nas formulações argumentativas, observamos que um caminho frequentemente utilizado na composição lógica de enunciados correspondentes a vozes ideológicas distintas é a colaboração enunciativa por via de pontos de contato semânticos e axiológicos entre as proposições.
OS VERDADEIROS VERBOS MODAIS DA LÍNGUA INGLESA A PARTIR DE UMA PERSPECTIVA DIACRÔNICA: AS SIGNIFICAÇÕES ATRELADAS À SEMÂNTICA DE MUNDOS POSSÍVEIS
Authors: Belando Mariane Garin
Published: April 2019

Este artigo tem por objetivo considerar que as noções semânticas estabelecidas aos verdadeiros verbos modais da língua inglesa necessitam ser relacionadas e analisadas diacronicamente, para uma melhor depreensão de suas funções. A hipótese é a de que a repetição de uso de determinados itens lexicais os tornou funcionais, até atingirem a leitura epistêmica, gerando mudança de escopo em relação às proposições. Mas, para isso, considera-se que a modalidade voltada para o agente se tornou crucial para que a gramaticalização destes verbos se instaurasse na língua. As considerações finais sugerem que tal processo evolutivo é capaz de demonstrar que estes verbos são, na verdade, polissêmicos, cujas significações estão veiculadas ao conceito de mundos possíveis, em referência às possibilidades dos fundos conversacionais.
O Então em debates orais: um estudo funcionalista
Authors: Moura Mateus Rodrigues de , Defendi Cristina Lopomo
Published: April 2019

Neste artigo, descrevemos o “então” como estrutura linguística típica de argumentação do Português oral do Brasil e apresentamos, como metodologia, a análise qualitativa a partir de dados coletados de um corpus composto por debates orais disponíveis nos canais do Youtube. Como resultado, após mapeamento das funcionalidades deste elemento linguístico em textos orais, constatamos dois usos característicos: ora como um operador argumentativo conclusivo – em que há classes argumentativas distintas, mas uma única orientação de argumentação – e ora como um marcador conversacional – iniciador de turno anafórico.

AVALIAÇÃO DE IMPACTOS E DANOS AMBIENTAIS EM ZONAS COSTEIRAS DO BRASIL - ANGRA DOS REIS E PARATY
Authors: Ribeiro Bianca Alves Lima , Wolff Nicole Martins , Da Silva Elenice Rachid , De Almeida Josimar Ribeiro
Published: April 2019

Os ambientes costeiros do estado do Rio de Janeiro sofrem um contínuo processo de degradação, associado a diversas atividades que promovem alterações significativas na estrutura de seus ecossistemas (INEA, 2014). Por isso, o objetivo deste estudo consiste em identificar os impactos e danos ambientais e as ações desenvolvidas para a melhoria da qualidade de vida e preservação da biodiversidade das zonas costeiras dos municípios de Angra dos Reis e Paraty, de acordo com a metodologia do modelo Pressão-Estado-Impacto-Resposta (PEIR). As informações sobre o estado do ambiente têm grande importância prática e teórica, visto que a partir delas é possível elaborar um planejamento para minimizar as pressões e impactos sobre o meio ambiente e potencializar as respostas em favor da preservação da biodiversidade e promoção da melhoria da qualidade de vida e bem-estar da população. Na primeira etapa, os dados foram coletados através de pesquisa bibliográfica e organizados em infográficos e tabelas. Na segunda etapa, os resultados foram analisados e discutidos sob a perspectiva do modelo PEIR. Foi observado que os municípios em estudo necessitam de melhorias na infraestrutura urbana básica, o que influencia diretamente na qualidade de vida e saúde da população. Em contrapartida, há iniciativas para a conservação da biodiversidade, como a manutenção de Unidades de Conservação e adesão do município de Paraty ao Passaporte Verde.
A synopsis of the Lyctine beetles of Eurasia with a key to the species (Insecta: Coleoptera: Bostrichidae: Lyctinae)
Authors: LIU LAN-YU , GEIS KLAUS-ULRICH
Published: April 2019

We provide an annotated synopsis of all the Eurasian Lyctinae with a key to all three tribes, seven genera and thirty-eight species. We provide for each species a summary of what is currently known about its taxonomic status, distribution, host plants, biology, and economic importance as a baseline for future studies of the fauna, particularly in relation to the growing importance of lyctines as economically important pests in the region.
Serum 25-Hydroxyvitamin D Concentrations from Patient Groups at High Risk for Deficiency
Authors: Wu Alan H B , Ghosh Rohit , Mei Ong Chui , French Deborah
Published: April 2019

Background

Deficiency of 25-hydroxyvitamin D in serum is endemic in the general population, and testing for this hormone is useful in accessing a patient's overall health and well-being.

Methods

We obtained blood from 216 hospitalized patients and outpatients divided into 4 groups thought to be at high risk of 25-hydroxyvitamin D deficiency: homeless, recreational drug abusers, psychiatric patients with limited access to the outdoors, and those infected with HIV. The 25-hydroxyvitamin D concentrations from these patients were determined with 2 different methodologies (immunoassay and mass spectrometry) and compared against 25-hydroxyvitamin D concentrations in apparently healthy controls. We hypothesized that these groups may be at higher risk for vitamin D deficiency because of poor nutrition, inadequate housing, restricted access to outdoors, or the presence of chronic disease.

Results

For each of the patient groups including healthy controls, the median concentration of 25-hydroxyvitamin D was below 30 ng/mL, indicating deficiency. Comparisons between the healthy controls and the other groups were not statistically significant with either methodology, except for the homeless patients in whom a higher number of individuals had 25-hydroxyvitamin D concentrations below 20 ng/mL. Results between the 2 testing platforms demonstrated that only 52% of the specimens analyzed by immunoassay agreed within ±10% of the LC-MS/MS results, with an overall correlation coefficient to 0.920. The degree of concordance for deficiency with 2 published cutoffs of 20 and 30 ng/mL was 91% and 91%, respectively.

Conclusions

Vitamin D deficiency is a common finding in all the populations studied. The Lumipulse® G vitamin D immunoassay is an alternative for detecting vitamin D deficiency.
Say there’s no future: The queer potential of Wicked’s Fiyero
Authors: Greenwood Steven
Published: April 2019

This article demonstrates the queer potential and pleasure produced by the character Fiyero in Stephen Schwartz and Winnie Holzman’s Wicked (2003). I mobilize two primary frameworks to examine Fiyero’s queerness; the first half of the article views Fiyero in the context of queer theories of temporality and utopia, while the second half is interested in the deep cultural history of gay men’s relationships with Broadway musicals. This analysis produces both theoretical and historical implications of Fiyero’s character as I explore how his representation disrupts heteronormative rituals and aspects of the social order, as well as how he produces a valuable figure for the communities of gay men that have historically developed around musical theatre. The queer possibility of Wicked’s women has been examined extensively in past scholarship – particularly through the insights of Stacy Wolf – and this article expands upon this previous work to account for the role of Fiyero in the musical and the queer possibilities he produces.
Bible, religion and Catholicism in Sting’s album and musical The Last Ship
Authors: Marienberg Evyatar
Published: April 2019

Sting, aka Gordon Sumner (b. 1951 in Wallsend, close to Newcastle upon Tyne), is a famous songwriter and performer who grew up in a Catholic environment. Although he does not identify as Catholic anymore, the religious images and notions he grew up with appear rather frequently in his work. This article explores examples of religious imagery in his album The Last Ship (2013), and in the musical of the same name based on the album. To date, the musical has been produced from two very different books: a US version by John Logan and Brian Yorkey (2014), and a UK one by Lorne Campbell (2018). The US version includes many religious notions, and in particular, includes a priest as one of its central figures. The UK version has little to no religion in it. The article suggests that each of these versions reflects a certain historical moment in the life of Wallsend, from where, supposedly, the ‘last ship’ was launched.
The Radio City Rockettes and the making of a sisterhood
Authors: Gibbons Oehlers Adrienne
Published: April 2019

Since their origins in 1925, the Radio City Rockettes have been a self-proclaimed sisterhood that has long been viewed as wholesome family entertainment. Although dancers for the Rockettes have had to submit to stringent guidelines of physicality, personality and uniformity, most alumnae are quick to wax poetic on their years in the line. This article investigates the meaning and the making of such sisterhood by looking at how a ‘community of practice’ is created through the structure of the company and the shared labour involved in precision dance. Their group dynamic and joint performance goals, along with the stable workplace and practices of Radio City Music Hall, shaped how the Rockettes’ identity was formed and propagated, in a way that differed from other more sexualized dance companies, which existed in the same era.
The Last Ship from Broadway to Newcastle: A feminist political musical for the Brexit era
Authors: Browne Sarah
Published: April 2019

Sting’s musical, The Last Ship premiered on Broadway in 2014. Four years later, following a series of workshops at Northern Stage, the musical embarked on its UK tour featuring a number of revisions to its narrative and structure. What emerges from the revised production is a narrative, which places women at the centre through affording them agency and allowing them to occupy powerful, liminal spaces. Whilst The Last Ship remains a tale for the working classes, its UK revisions do well to reposition the central role of the women in this community. Through removing principal characters, which previously served to reinforce a patriarchal hierarchy, the fictional women of Wallsend now drive the plot, allowing for The Last Ship to communicate a morality tale, which echoes the ideologies of a feminist, post-Brexit era.
