Published: May 2017

In today’s world, management has a great influence on functioning and development of enterprises. The process of personnel management carries one of the main components of the process — adaptation. The issues of professional adaptation were investigated both in domestic and in foreign publications. Despite the large number of scientific works devoted to problems of adaptation of the personnel, the topic is still relevant, since many organizations do not pay enough attention to this process.
In this paper, we have investigated one of the functions of personnel management — adaptation. Various literatures on the problems of professional adaptation was reviewed, the concept of “professional adaptation” is described, many factors that influence the adaptation of the staff are analyzed and presented. Also, we carried out a study to identify the problems inherent in the process of professional adaptation of employees in the industrial sector. On the basis of results the main problems were presented identified in the course of the study and some recommendations for elimination of deficiencies discovered in the process of adaptation in the industrial sector.

CONCEPT DEVELOPMENT OF BUSINESS-PROCESSES MANAGEMENT BASED ON THE PRINCIPLES OF SYNERGY
Authors: Казаков Олег , Kazakov Oleg 
Published: May 2017

The importance of research aimed at developing the management concept of business-processes on the basis of the principles of synergy from the scientific-theoretical point of view is caused by the absence of design ways in modern methodology, reengineering and automation of business-processes allowing to con-sider the economic entity as a dissipative structure.
From the scientific and practical point of view the urgency of research is caused by necessity of commer-cial and non-commercial organizations forthe system of tested techniques and information management systems of business processes of socio-economic systems in the context of task support formed by the automated system to the person and also tasks like "person-person".
The author has developed the management con-cept of business-processes on the basis of self-organization principles, defined the economic man-agement tools reflecting elements of synergy: attractor, fluctuation, fractal, bifurcation point.
The common notation system of a broadened management concept of business-processes is devel-oped, and also the psycho-economic simulation model of labor productivity dependence on the level of emo-tional state is developed that will allow to increase effi-ciency of strategic and operational planning, and to develop high-quality information services by IT spe-cialists.

Aims The aim of this study was to assess hypertrophy of the extra-articular tendon of the long head of biceps (LHB) in patients with a rotator cuff tear. Patients and Methods The study involved 638 shoulders in 334 patients (175 men, 159 women, mean age 62.6 years; 25 to 81) with unilateral symptomatic rotator cuff tears. The cross-sectional area (CSA) of the LHB tendon in the bicipital groove was measured pre-operatively in both shoulders using ultrasound. There were 154 asymptomatic rotator cuff tears in the contralateral shoulder. Comparisons were made between those with a symptomatic tear, an asymptomatic tear and those with no rotator cuff tear. In the affected shoulders, the CSAs were compared in relation to the location and size of the rotator cuff tear. Results The mean CSA was 21.0 mm2 (4 to 71) in those with a symptomatic rotator cuff tear, 19.9 mm2 (4 to 75) in those with an asymptomatic rotator cuff tear and 14.1 mm2 (5 to 43) in those with no rotator cuff tear. The mean CSA in patients with both symptomatic and asymptomatic rotator cuff tears was significantly larger than in those with no rotator cuff tear (p < 0.001). In the affected shoulders, there were significant differences between patients with more than a medium sized posterosuperior cuff tear and those with an antero-superior cuff tear. Conclusion Regardless of the symptoms, there was significant hypertrophy of the extra-articular LHB tendon in patients with a rotator cuff tear. The values were significantly related to the size of the tear. Cite this article: Bone Joint J 2017;99-B:806–11.

Published: May 2017

Purpose Early detection and intervention for developmental dysplasia of the hip (DDH) is important for normal hip development. Previous studies have shown disparities in access to paediatric specialty care among different racial and socioeconomic backgrounds. This study aims to identify whether these factors are related to timely referral for infants with DDH. Methods A retrospective cohort study of patients seen and treated for DDH between July 2006 and June 2011 at a single institution were reviewed. The patients were divided into early-presenting (seen before six months of age) and late-presenting patients (seen at six months of age or later). Results A total of 457 patients met the eligibility criteria. There were 378 early and 79 late presentations. Late presentations were significantly more likely to be vertex at birth (85% vs 41%, p < 0.001). Bivariate analysis also demonstrated that late presentations were more likely to be non-white (65% vs 45%, p = 0.004), non-English speaking (20% vs 8%, p = 0.003), from lower income areas ($70 769 vs $61 591, p < 0.001) and hold public insurance (25%, p = 0.001). However, a logistic multiple regression analysis showed that only vertex birth presentation (p = 0.000), absent family history of DDH (p = 0.047) and affected right side (p = 0.001) were significantly associated with late presentation. Conclusion Despite screening algorithms to facilitate early diagnosis of infants with DDH, better research is needed to understand how different demographic and socioeconomic factors play into the delayed access to paediatric orthopaedic care for DDH so that we may ultimately improve rates of early treatment.
Hostage to hospitality: Is there a relationship between ‘sexual hospitality’ and sex in commercial hospitality?
Authors: Wijesinghe Gayathri 
Published: May 2017

Abstract
This article, through the prism of ‘sexual hospitality’ explores the tradition of the sexualized, objectified and later commodified roles imposed on women through their hospitality provision. Sexual hospitality was an ancient custom whereby the host provided a hostess from his household to the male guest for his sexual pleasure. It is argued that in the transition to contemporary commercial hospitality, women’s sexuality became a commodity employed to attract customers. In the past, hostess-guest behaviour was endorsed by societal and religious beliefs, whereas in the commercial sphere today, the sexualization of hospitality workers in some hospitality establishments, while not officially endorsed, nonetheless creates ambiguous and dangerous workplaces. There is a risk involved for servers as some customers still view women’s bodies as being available for their enjoyment in the hospitality encounter. A broad sweep of the literature indicates that commercial hospitality not only to some extent legitimizes, reinforces and perpetuates these historical gender stereotypes (both male and female), and unequal power relations, but also eroticizes hospitality, making it ‘sexy’, and leaving room for potential degradation and sexual violence. Studies that are more focused on specific time and cultural contexts are encouraged to consider whether contemporary servers are still hostage to patriarchal hospitality through the sexualized commodification of their labour.
Conspicuous conservation: The green clothing of Swedish environmentalists
Authors: Lisberg Jensen Ebba , Elahi Babak 
Published: May 2017

Abstract
Focusing on the notion of ‘green clothing’, this article shows how a sartorial aesthetic informs group cohesion for environmentalist activists. Using qualitative data gathered through open-ended questions posted on the Field Biologists’s Facebook group, which is no longer active, the article explores subjects’ memories and opinions on clothing and style covering the period from the late 1960s to the present. The article mixes this method with historical textual analysis of the tradition of frugality and asceticism back to nineteenth-century forerunners. This mixed method approach provides rich material on counter-consumerist aesthetics in both cultural and political contexts within a historical framework. Theoretically, the article revises the classic notion of clothes as a cultural membrane between body and society, showing how a third element – nature – works in certain ideological frames to dissolve that membrane between body and society. In this way, clothes are worn in order to demonstrate harmony between the wearer’s body and the environment. This dissolution of culture into ‘nature’ serves the collective pursuit of political community espoused by the Field Biologists. Through tracing a number of ‘vestemes’ (units of sartorial semiotics), this article decodes an identity formed around nature as opposed to culture; the old as opposed to the new; second- as opposed to first-hand; as well as around a complex relationship with gender.

AbstractThe neuromuscular junction has retained through evolution the capacity to regenerate after damage, but little is known on the inter‐cellular signals involved in its functional recovery from trauma, autoimmune attacks, or neurotoxins. We report here that CXCL12α, also abbreviated as stromal‐derived factor‐1 (SDF‐1), is produced specifically by perisynaptic Schwann cells following motor axon terminal degeneration induced by α‐latrotoxin. CXCL12α acts via binding to the neuronal CXCR4 receptor. A CXCL12α‐neutralizing antibody or a specific CXCR4 inhibitor strongly delays recovery from motor neuron degeneration in vivo. Recombinant CXCL12α in vivo accelerates neurotransmission rescue upon damage and very effectively stimulates the axon growth of spinal cord motor neurons in vitro. These findings indicate that the CXCL12α‐CXCR4 axis plays an important role in the regeneration of the neuromuscular junction after motor axon injury. The present results have important implications in the effort to find therapeutics and protocols to improve recovery of function after different forms of motor axon terminal damage.

Published: May 2017

Background: Non-Langerhans histiocytosis is a group of inflammatory lymphoproliferative disorders originating from non-clonal expansion of hematopoietic stem cells into cytokine-secreting dendritic cells or macrophages. Erdheim-Chester Disease (ECD) is a rare type of non-Langerhans cell histiocytosis characterized by tissue inflammation and injury caused by macrophage infiltration and histologic findings of foamy histiocytes. Often ECD involves the skeleton, retroperitoneum and the orbits. This is the first report documenting ECD manifesting as segmental colitis and causing cytokine-release syndrome.Case presentation: A 68-year old woman presented with persistent fever without infectious etiology and hematochezia. Endoscopy showed segmental colitis and pathology revealed infiltration of large foamy histiocytes CD3-/CD20-/CD68+/CD163+/S100- consistent with ECD. The patient was empirically treated with steroids but continued to have fever and developed progressive distributive shock.Conclusion: This case report describes the differential diagnosis of infectious and immune-mediated inflammatory and rheumatologic segmental colitis. Non-Langerhans histiocytosis and ECD are rare causes of gastrointestinal inflammation. Prompt diagnosis is imperative for the appropriate treatment to prevent hemodynamic compromise due to distributive shock or gastrointestinal bleeding. Importantly, gastrointestinal ECD might exhibit poor response to steroid treatment and other potential treatments including chemotherapy, and biologic treatments targeting IL-1 and TNF-alpha signaling should be considered.Abbreviations: AFB: acid-fast bacilli; ECD: Erdheim-Chester Disease; IBD: inflammatory bowel disease; PASD: periodic acid-Schiff with diastase; TB: tuberculosis

Background & Aim: Endoscopic balloon dilation (EBD) and laparoscopic Heller myotomy (LHM) are the most commonly performed treatment options for achalasia. Decision between these treatment options is difficult. The aim of this meta-analysis was to evaluate the efficacy of EBD compared to LHM.Methods: The electronic databases PubMed, Embase and Cochrane Controlled Trials Registry were systematically searched for the period between January 1, 1976 and December 31, 2015. Meta-analysis was performed using the PICOS (problem, intervention, comparison, outcome, study design) format. Efficacy and safety of EBD were compared to LHM. Forest plot analyses were used to illustrate the success rate, perforation rate and post-procedural gastroesophageal reflux.Results: Using the search strategy, eight studies met the selection criteria and were included in the meta-analysis. The total number of patients included was 749 (360 in the EBD group and 389 in the LHM group). The success rate was lower in the EBD group than in the LHM group (OR=0.486; CI: 0.304-0.779; p=0.003). The rate of perforation did not differ significantly between the EBD and LHM group (RR= 0.635, CI: 0.340-1.186, p=0.154). The incidence of post-procedural symptomatic gastroesophageal reflux did not differ between the two treatment groups (RR=0.663, CI: 0.328-1.343, p=0.254).Conclusion: Our data suggest that the efficacy of LHM is superior to that of EBD, while there is no difference in safety between the two treatment groups.Abbreviations: EBD: endoscopic balloon dilation; GERD: gastro-esophageal reflux disease; LES: lower esophageal sphincter; LHM: laparascopic Heller myotomy; OR: odds ratio; PICOS: Problem, Intervention, Comparison, Outcome, Study design; POEM: Per Oral Endoscopic Myotomy; PRISMA: Preferred Reporting Items for Systematic Reviews and Meta-Analysis; RR: risk ratio.

Published: May 2017

Background & Aims: Neuroendocrine tumors (NETs) are a heterogeneous group of neoplasms with unclear etiology that may show functioning or non-functioning features. Primary tumor localization often requires integrated imaging. The European Neuroendocrine Tumors Society (ENETS) guidelines proposed wireless-capsule endoscopy (WCE) as a possible diagnostic tool for NETs, if intestinal origin is suspected. However, its impact on therapeutic management is debated. We aimed to evaluate the yield of WCE in detecting intestinal primary tumor in patients showing liver NET metastases when first-line investigations are inconclusive.Method: Twenty-four patients with histological diagnosis of metastatic NET from liver biopsy and no evidence of primary lesions at first-line investigations were prospectively studied in an ENETS-certified tertiary care center. Wireless-capsule endoscopy was requested before explorative laparotomy and intra-operative ultrasound. The diagnostic yield of WCE was compared to the surgical exploration.Results: Sixteen subjects underwent surgery; 11/16 had positive WCE identifying 16 bulging lesions. Mini-laparotomy found 13 NETs in 11/16 patients (9 small bowel, 3 pancreas, 1 bile ducts). Agreement between WCE and laparotomy was recorded in 9 patients (Sensitivity=75%; Specificity=37.5%; PPV=55%; NPV=60%). Correspondence assessed per-lesions produced similar results (Sensitivity=70%; Specificity=25%; PPV=44%; NPV=50%). No capsule retentions were recorded.Conclusions: Wireless-capsule endoscopy is not indicated as second-line investigation for patients with gastro-entero-pancreatic NETs. In the setting of a referral center, it might provide additional information when conventional investigations are inconclusive about the primary site.Abbreviations: DBE: double balloon enteroscopy; GEP-NET: gastro-entero-pancreatic neuroendocrine tumor; GI: gastrointestinal; ENETS: European Neuroendocrine Tumor Society; NET: neuroendocrine tumor; SSRS: somatostatin receptor scintigraphy; WCE: wireless capsule endoscopy.

The focus is the “formation for citizenship”, only possible “by the citizenship”, as consciousness process by the individuals, according to the critical perspective adopted. In addition to literature review, interviews were conducted with experts of distance modality from Brazil, Portugal and Venezuela. The work considers that a citizenship education is able to contribute to the emancipation by the individuals in any modality. And discusses data and situationsregarding distance education proposing the following conditions: education by citizenship; collective work; mediated (dialectical mediation) dialogue by the world; participative and flexible design instructional; coherent study materials;and articulation with network social movements.
Corpo/matéria, gestos/material: para pensar uma estética dos esportes
Authors: Gonçalves Michelle Carreirão , Vaz Alexandre Fernandez 
Published: May 2017

Ao se pensar em uma estética dos esportes a partir da análise de material oriundo de pesquisa empírica realizada com uma equipe de rúgbi feminino sediada na cidade de Florianópolis (SC), trabalhou-se com a perspectiva de que o cotidiano de treinamento e o momento de jogo materializado nas disputas são tempos singulares de construção do que se denomina aqui obra esportiva. Esta, tomada como artefato estético em analogia à obra de arte, parece se aproximar desta no que concerne a seus elementos constituintes, como matéria, material e forma. Volta-se o olhar especialmente para os dois primeiros, encontrando, por um lado, o corpo como matéria, materialidade que permite o modelamento e a modificação; e, por outro, os gestos técnicos, o vocabulário específico de cada modalidade, configurando-se como o material da obra esportiva.
Currículo, experimento e experiência: contribuições da Educação em Ciências
Authors: Ferraro José Luís Schifino 
Published: May 2017

Ao tomar como ponto de partida a possibilidade da problematização para (res)significar elementos essenciais ao ensino das Ciências da Natureza, lança-se por sobre o currículo um olhar ético-estético que reforça a necessidade e o direito de o aluno experienciar sem desconsiderar a importância da experimentação na construção de conhecimentos específicos da área. Considerando a dualidade experiência/experimento, o trabalho que segue não pretende evidenciar a necessidade de sobreposição uma sobre outra, mas discuti-las para que se possa resgatar a dimensão de transformação inerente ao conceito de educação muito além da pura aplicabilidade e domínio da técnica.
The university-industry relationship under diferent approaches: the entrepreneurial university to academic capitalism
Authors: Cristofoletti Evandro Coggo , Serafim Milena Pavan 
Published: May 2017

The economic and political changes in the world, from the 1970s, changed the political education of the Public Institutions of Higher Education in the world. The direction of these changes was clear: the university approachedthe market and the company and created interaction mechanisms that did not exist. The article therefore reviews the academic literature that interprets the relationship between university and market/company from two perspectives: approaches that positively position of interactions, exposing their motivations, interests and forms of interaction, especially the notions on Knowledge Economy and Entrepreneurial University; approaches that observe this interaction critically and reflectively, exposing the problems of interaction, its negative aspects and the reflection of the true role of the public university from the perspective of Academic Capitalism.
