Bridging the Gap: A Pilot Program to Understand and Meet the Needs of Pediatric Patients and Families as They Transition Off Cancer-Directed Therapy
Authors: Shea Kathleen A. , Steinberg Dara M. , Santiago Rebecca A.
Published: December 2018

Background: With improved curative therapies, over 80% of children and adolescent/young adults diagnosed with cancer are expected to live into adulthood. This population is at risk for increased morbidity and early mortality and requires ongoing health care and surveillance for late effects of treatment. This pilot study assessed the acceptability of a structured medical visit at the completion of cancer-directed therapy as well as patient/family’s knowledge of diagnosis and other aspects of care. Method: Patients/families who were 0 to 6 months from completion of cancer-directed therapy attended a one-time transition visit during which they completed a series of questionnaires assessing knowledge about diagnosis, treatment, potential late effects, and duration of ongoing care. They were then given treatment summaries, a plan for follow-up care, information about care after treatment as well as late effects. They completed a questionnaire to assess their satisfaction with this visit. Results: The majority of patients/families knew their diagnosis and treatment modalities. Less knew that their treatment put them at risk for cardiac toxicity or problems with future fertility. A significant number thought follow-up care would continue for only 5 years. Overall participants were satisfied with the visit. Conclusion: The transition period from on to off therapy may be a critical time point to provide patients with cancer and their families with information regarding treatment, follow-up care and testing, and potential late effects. Future studies should assess if this intervention improves compliance with recommended care and surveillance, and improved outcomes.
Sexual Aging: A Systematic Review of Qualitative Research on the Sexuality and Sexual Health of Older Adults
Authors: Sinković Matija , Towler Lauren
Published: December 2018

Negative stereotypes regarding the sex lives of older adults persist, despite sexuality being an important factor that influences the quality of life. We conducted a systematic review of the qualitative literature on the sexuality and sexual health of older adults to address which topics have been researched and the quality of research within this field. We searched PsycINFO, SocINDEX, MEDLINE, and CINAHL for qualitative articles investigating the sexuality of adults aged 60+ years. We analyzed 69 articles using thematic analysis to synthesize their findings. We identified two overarching thematic categories: psychological and relational aspects of sexuality (personal meanings and understandings of sex, couplehood aspects, and sociocultural aspects) and health and sexuality (effects of illness and/or treatment on sexuality, and help-seeking behaviors). Research is needed into male sexual desire and pleasure, culture-specific and sexual/gender identities and their effect on outcomes such as help-seeking behavior and sexual satisfaction, and sexual risk-taking in older adults.
“A Huge, Hidden Problem”: Australian Health Practitioners’ Views and Understandings of Reproductive Coercion
Authors: Tarzia Laura , Wellington Molly , Marino Jennifer , Hegarty Kelsey
Published: December 2018

Reproductive coercion is understood as behavior interfering with a woman’s reproductive autonomy. It is usually perpetrated by a male partner, and sometimes by other family members. Reproductive coercion encompasses violence, threats, or coercion to force a woman to become or remain pregnant, or to terminate a pregnancy. To date, few studies have focused on this topic, particularly using qualitative methods. In this article, we aim to explore how Australian health practitioners understand and perceive reproductive coercion. We conducted semistructured interviews with health practitioners from an Australian public hospital, and the resulting data were analyzed thematically. Overall, reproductive coercion was described as complex and hidden. There were diverse understandings around its parameters and scope, which were shaped by the participants’ disciplines and paradigms. Our findings point toward a need for greater clarity around reproductive coercion and how it sits within a broader framework of violence against women, to facilitate cross-disciplinary collaborative responses.
Contingent Imitation and Young Children At-Risk for Autism Spectrum Disorder
Authors: Killmeyer Susan , Kaczmarek Louise , Kostewicz Douglas , Yelich Amy
Published: December 2018

Autism Spectrum Disorder (ASD) is a neurodevelopmental disorder characterized by early and pervasive deficits in social orienting and social engagement. Although parent-implemented interventions using a range of responsive interactive techniques have demonstrated effectiveness to increase social engagement, more work is needed to examine how best to support a responsive parental style to increase social engagement in an exceptionally heterogeneous population. Emerging evidence suggests that contingent imitation (CI) may be a uniquely effective way to increase social engagement in children with ASD. This study used a multiple-baseline single case design across participants to examine how three caregivers learned to use CI at home with fidelity with their young children at-risk for or who had ASD. Results demonstrated that parents quickly acquired the accurate use of this simple technique at home. Furthermore, using CI with fidelity, caregivers sharply reduced their use of questions and directives during play. After caregivers were taught the CI procedure, positive changes in child social eye gaze were seen across intervention and maintenance phases. Implications for research and early intervention practice are discussed.
Getting to the CORE: Putting an End to the Term “Soft Skills”
Authors: Parlamis Jennifer , Monnot Matthew J.
Published: December 2018

We need to retire the term “soft skills.” A new vocabulary for describing critical social and organizational skills is long overdue. Substituting the acronym “CORE” (Competence in Organizational and Relational Effectiveness) for the loaded word “soft” provides a more fitting term for the important skills the term describes and, in doing so, reframes the perceptions of these key skills to reflect their importance for career and organizational success.
Music Teachers’ Perspectives on Live and Video-Mediated Peer Observation as Forms of Professional Development
Authors: Bautista Alfredo , Wong Joanne , Cabedo-Mas Alberto
Published: December 2018

The purpose of this interview study, conducted with 12 primary music teachers in Singapore, was to determine whether peer observation is viewed as a learning approach that may contribute to professional growth. We found that both specialist and generalist music teachers highly valued peer observation and were optimistic about the use of video-mediated peer observation. As a form of professional development, peer observation appears to enhance understanding and application of teaching strategies, allows teachers to anticipate students’ reactions during lessons, and builds their confidence as instructors. Video-mediated peer observation, which is both convenient and easily accessible, provides contextualized examples of effective classroom practices. We conclude that peer observation activities are most meaningful and transformative when they are responsive, that is, designed with music teachers’ voices and professional development needs in mind.
A Sometimes Hidden Economic Dimension to Individual Immigration Preferences: Cross-National Evidence in Support of the Labor Competition Hypothesis
Authors: Bearce David H. , Roosevelt Megan
Published: December 2018

This paper seeks to restore labor competition as an explanation for anti-immigration attitudes, recognizing that education may proxy both individual-level skill and cultural socialization. We thus need new tests to distinguish the effect of education based on skill from that due to socialization. If the education effect is consistent with these relationships, then we can have greater confidence that it is capturing the former and not simply the latter. This paper thus develops and conducts a new test, using data from the International Social Survey Program’s National Identity Survey fielded in 2013 across thirty-two countries. From a factoral framework, our test identifies three national-level factors that should influence how much labor market pressure lower skilled citizens feel from immigration: the quantity of immigrants, the direction of capital/investment flows, and the amount of trade protection. These national-level factors are interacted with individual-level education, showing that the attitudinal differences based on education increase with more immigrants but decrease with greater investment inflows and increased trade protection. These results demonstrate why this economic dimension may sometimes be hidden: in national contexts where there are few immigrants, capital follows labor, and/or there is trade protection, labor competition as a driver of anti-immigration preferences should lessen.
A Life History of Place: A Future Place for Life Histories?
Authors: Spooner Marc
Published: December 2018

Diverse in nature, style, and approach, life histories enjoy a rich and established position within the broader narrative and qualitative research traditions. Nevertheless, such a position may be rendered considerably more complicated given new technologies and post-humanist developments. Rather than shy away from such new complexities, the life history field, it is argued, should embrace these developments and explore the fertile ground that might well lie at the intersections of the postqualitative, Indigenous, and place-based turns. What happens when “place” becomes the central character—the complex, entangled protagonist—of a life history focus? Exploring just such a re-imagining, this article examines the potential for creating fecund new ground for a life history of place. As a concrete example—although perhaps an unlikely source for inspiration—Phil Jenkins’s An Acre of Time: The Enduring Value of Place will be offered as a potential prototype.
“Real Flight and Dreams of Flight Go Together”: High Technology and Imaginary Heights in Early Modern and Postmodern Science Fiction
Authors: Engelhardt Nina
Published: December 2018

This article examines how science fiction literature illustrates that exploring the “space above” and journeys toward it necessitates engaging with different types of knowledge, not least scientific-technological and imaginative ones. Scholarship in geography and urban and social studies has recently experienced what has been called a “vertical turn,” that is, a growing attention to the third dimension of space, and researchers call for more interdisciplinary experiments and commitment. This article argues that fictional literature is a valuable source of inquiry and, moreover, that it is precisely science fiction itself that illustrates the need to draw on various types of knowledge in order to explore issues of verticality and the space above. It examines an early modern text from a period before technological ascent into space became possible and a 20th-century novel set at the beginning of the rocket age: Francis Godwin’s The Man in the Moone; or a Voyage Thither, written sometime after 1628 and published in 1638, and Thomas Pynchon’s Gravity’s Rainbow (1973). Both texts illustrate that scientific-technological and imaginative investigations of “the above” are inseparable and emphasize the role of the imagination in fictional as well as in technological ascents. Moreover, in these texts, travelling into the space above involves complex ethical and moral dimensions. Exploring these in relation to the inseparability of scientific-technological and imaginative investigations, the analysis of the science fiction texts also develops the ethical and cognitive value of making scholarly analysis of verticality an interdisciplinary endeavor.
Subversive identity and cultural production by the Russian-Israeli Generation 1.5
Authors: Remennick Larissa , Prashizky Anna
Published: December 2018

This article belongs to the series presenting our ongoing ethnographic project on the Russian-Israeli Generation 1.5. It discusses the nexus between immigrant identity, civic activism and cultural production among young adults born in the (former) Soviet Union, who migrated to Israel as older children or adolescents. We examine the new, protest-driven activism among young Russian Israelis while drawing on the concepts of reactive ethnicity and cultural public sphere. This identity quest occurs at the intersection of their Russian, Jewish and Israeli identities that often clash with each other. Moreover, the ethnic awakening among these young immigrant adults has been clearly gendered, with mostly female leadership emerging out of its cultural avant-garde. We present and discuss examples of the media discourse, artistic and creative events organized by Generation 1.5 leaders, focusing on the recent Russian–Hebrew poetry festival in Jerusalem.
Fibre reinforced polymer for strengthening cylindrical metal shells against elephant’s foot buckling: An elasto-plastic analysis
Authors: Batikha Mustafa , Chen Jian-Fei , Rotter J Michael
Published: December 2018

This article describes the use of fibre reinforced polymer composites to increase the strength of an isotropic metallic cylindrical shell against elephant’s foot buckling. This form of buckling occurs when a cylindrical shell structure is subjected to high internal pressure together with an axial force, such as those that may occur in tanks and silos. It is particularly relevant to tanks under seismic action. Although fibre reinforced polymer composites have been widely applied to different types of structures under several loading conditions, its use to strengthen thin steel cylindrical shells has been very limited. Here, a non-linear elasto-plastic finite element idealisation is used to explore the strengthening effect of a fibre reinforced polymer strip on a thin cylinder. The optimum size and position of the fibre reinforced polymer sheet were obtained and empirically formulated. This study has shown that the strength after repair is sensitive to minor changes in the fibre reinforced polymer parameters so that a close adherence to the optimum parameter values is very desirable.
Reassessing the “rules of the game”: Max Weber and Peter Winch on rule-following
Authors: Sivado Akos
Published: December 2018

Peter Winch’s critical remarks concerning Max Weber’s interpretive sociology are centered around the notions of “rule” and “rule-following.” While Winch gave credit to Weber for much of his theoretical insight, he nevertheless found his account unsatisfactory for two reasons: its neglect of rules and rule-following in social life, and its apparent reliance on causal explanations. This article attempts to show how Winch might have been less than charitable on both of these accounts: that once one pays close attention to Weber’s concept of a “rule,” and to his ideas concerning “adequate causation,” the two frameworks for interpretive sociology could turn out to be much more similar than it is usually assumed.
“We the People”: Epistemological Moves Through Cultural Praxis
Authors: Quijada Cerecer David Alberto , Cahill Caitlin , González Coronado Yvette Sonia , Martinez Jarred
Published: December 2018

How do young people embody activism and artistic praxis as they commit to community-based participatory action research for social change? We consider how the arts might provide a social and shared context for challenging racialized characterizations. Our analysis draws upon arts-based participatory action research projects conducted by the Mestizo Arts & Activism Collective ( https://maacollective.org ), a social justice think tank led by the urgent concerns of young people of color. Specifically, we engage the arts as integral to the research process—an epistemological move that opens up new ways of understanding and knowing our world and representing ourselves.
The Inhibition Kinetics and Potential Anti-Migration Activity of NQO1 Inhibitory Coumarins on Cholangiocarcinoma Cells
Authors: Khunluck Tueanjai , Kukongviriyapan Veerapol , Senggunprai Laddawan , Duangarsong Wutthipong , Prawan Auemduan
Published: December 2018

Altered expression of a cytosolic flavoenzyme NAD(P)H:quinone oxidoreductase-1 (NQO1) has been seen in many human tumors. Its remarkable overexpression in cholangiocarcinoma (CCA; an aggressive malignancy of the biliary duct system) was associated with poor prognosis and short survival of the patients. Inhibition of NQO1 has been proposed as a potential strategy to improve the efficacy of anticancer drugs in various cancers including CCA. This study investigated novel NQO1 inhibitors and verified the mechanisms of their enzyme inhibition. Among the different chemical classes of natural NQO1 inhibitors are coumarins, flavonoids, and triterpenoids. Coumarins are a group of particularly potent NQO1 inhibitors. The mechanisms and kinetics of enzyme inhibition of coumarin, aesculetin, umbelliferone, and scopoletin using the cell lysates as a source of NQO1 enzyme best fit with an uncompetitive inhibition model. Among the NOQ1 inhibitors tested in KKU-100 CCA cells, scopoletin and umbelliferone had the strongest inhibitory effect on this enzyme, while aesculetin and coumarin barely affected intracellular NQO1. All coumarins were further tested for cytotoxicity and anti-migration activity. At modest cytotoxic doses, scopoletin and umbelliferone greatly inhibited the migration of KKU-100 cells, whereas coumarin and aesculetin barely reduced cell migration. The anti-migration effect of scopoletin was associated with decreased ratio of matrix metalloproteinase 9/tissue inhibitors of metalloproteinases 1 ( MMP9/ TIMP1) mRNA. These findings suggest that natural compounds with potent inhibitory effect on intracellular NQO1 have useful anti-migration effects on CCA cells. In order to prove that the potent NQO1 inhibitor, scopoletin, is clinically useful in the enhancement of CCA treatment, additional in vivo studies to elucidate the mechanism of these effects are needed.

Published: December 2018

Context: Cancer-related fatigue (CRF) is one of the most burdensome symptoms in breast cancer survivors (BCSs), accompanied by reduced health-related quality of life (HRQOL). Objectives: This study investigated the influence of a multimodal therapy (MT; psychoeducation, eurythmy therapy, painting therapy, and sleep education/restriction), or a combination therapy (CT; MT plus aerobic training [AT]) on HRQOL in BCS with chronic CRF in comparison with AT alone. Methods: One hundred and twenty-six BCSs with CRF were included in a pragmatic comprehensive cohort study and allocated either per randomization or by preference to MT, CT, or AT. The EORTC QLQ-C30 core questionnaire was used to measure HRQOL. All analyses on HRQOL parameters were done in an explorative intention. Results: Patients were assigned to MT (n = 44), CT (n = 54), or AT (n = 28). CT was significantly superior to AT after 10 weeks of intervention (T1) in improving physical function. MT was found to have significant superiority over AT at T1 and T2 for physical functioning, emotional functioning, insomnia, and financial problems as well as role functioning, cognitive, social functioning, and fatigue 6 months later (T2). Conclusion: A multimodal approach appears to be a suitable concept for BCS with chronic CRF. A confirmatory study with larger samples should demonstrate the superiority of MT and adapted CT in HRQOL compared with the current treatment AT found in these explorative analyses.
An unmanned aerial vehicle optimal selection methodology for object tracking
Authors: Kopyt Antoni , Narkiewicz Janusz , Radziszewski Paweł
Published: December 2018

In this article, an optimal method of unmanned aerial vehicle selection for following a moving ground target is presented. The most suitable unmanned aerial vehicle from an aircraft operating fleet is selected for tracking task. The aircraft choice is done taking regarding the unmanned aerial vehicle distribution in the mission zone, individual performance of fleet platforms, and maneuverability of a ground platform. The unmanned aerial vehicle fleet members’ flying qualities are various, so an optimization process is used to assign an aircraft to follow the ground target. A target trajectory prediction is embedded in tracking algorithm. The simulation results demonstrated the effectiveness of algorithms developed, and in-flight demonstration proved the possibility of realization of computed trajectories by the unmanned aerial vehicle.
Modelling and numerical simulation of vibrations induced by mixed faults of a rotor system immersed in an incompressible viscous fluid
Authors: Tchomeni Bernard Xavier , Alugongo Alfayo
Published: December 2018

Extraction of features of a specific signal in fluid–structure interaction is among the hottest problems in the field of mechanics. Yet, a comprehensive study of such problems remains a challenge due to their high nonlinearity and multidisciplinary nature. The study presented in this article is focused on a particular engineering application of fluid–structure interaction. The governing equation of a spinning rotor submerged in an incompressible viscous fluid is modelled by means of well-established dissipative energy principle, yielding a highly coupled 3-degree-of-freedom system with strong nonlinear terms. A two-dimensional model of the Navier–Stokes equations for the incompressible flow is developed for the viscous fluid motion around the spinning rotor under high fluctuations induced by unbalance, rotor–stator rub and a crack. The extracted features through frequency spectrum, orbit patterns and rotor-coupled deflection revealed that the performances of rotor systems are highly impacted by the hydrodynamic terms which are the sources of multiple frequency response. The results showed that the complex fluid–rotor model yields good analysis of fault diagnosis, and responses at more than one parametric resonance appear and reach a point of complex feature extractions when more than one fault coexists in the system. Furthermore, a nonlinear denoising by thresholding the wavelet coefficients is performed to overcome the complexity of discretization and for effective multiple fault diagnoses.
Load-sharing analysis of two-stage three-branch star gearing based on deformation compatibility

Published: December 2018

A load-sharing analysis methodology was proposed for the multiple-branch star gear transmission which is composed of a number of closed-loop power flows. The moment equilibrium and deformation compatibility equations for the two-stage star gearing were derived, which are clearly different from that used in planetary gear transmission. Then the load-sharing analysis model was established and employed to systematically study the load-sharing behavior of the two-stage three-branch star gearing, some untouched aspects were investigated. Results show that the most sensitive directions of the central and star gear assembly errors on load-sharing are along the meshing line. The effects of the size and direction of the central gear–manufacturing errors on load sharing are the same for each branch, the initial directions of the central or a certain star gear–manufacturing errors will have no effect on the load-sharing coefficient of the system, but the initial directions of the assembly errors will. The conditions in which the load distribution curves repeat the first track were also obtained. Finally, a numerical example of a three-branch star gear aviation reducer was adopted to verify the feasibility of this proposed method, and the calculation results show good agreement with a previously published and validated model.

The role of mobile devices in 21st-century family communication
Authors: Storch Sharon L. , Ortiz Juarez-Paz Anna V.
Published: December 2018

Use of media devices has evolved over the past 10–15 years and the resulting effects on family communication are of interest for this study. Through 26 semi-structured interviews, the authors sought to understand the role mobile devices play in family communication. Qualitative grounded theory analysis was used to find themes and interpret results (Creswell, 2013). One overarching paradoxical theme emerged from these data, family connect–family disconnect. In family connect, categories of across distance, reassurances, and boundaries are shared. Within family disconnect, distractions, misunderstandings, and negative emotional responses are conveyed. Future research avenues recommended are decision making related to mobile devices based on values and morals, in-depth social media and app usage, emoji emotional responses, individuals under 18 and between 18 and 30 years old, and a network analysis of one extended family.
Portables, luggables, and transportables: Historicizing the imagined affordances of mobile computing
Authors: Alper Meryl
Published: December 2018

This article contributes to the history of “mobile media beyond mobile phones” by accounting for genres of portable computing (or “portables”) that emerged in the late 1980s. Though largely overlooked by historians of technology, these mobile, less-than-mobile, and relatively immobile devices helped shape the social and cultural uses of contemporary mobile communication. I argue that the technological capabilities of portables altered users’ expectations for how and where computers could be incorporated into daily life, be it near bodies, on hand, or at one’s fingertips. While the market for bulky portables dwindled by the late 1990s, as laptops and cell phones became more ubiquitous, these consumer electronics are nonetheless useful today for understanding the perpetual role of materiality and embodiment in how we conceive of the imagined affordances of mobile communication technologies.
Patient expectations of hypertension and diabetes medication: Excessive focus on short-term benefits
Authors: Gibson Demetra S , Nathan Aviva G , Quinn Michael T , Laiteerapong Neda
Published: December 2018

Objectives:

The objectives of this study are to assess patient perspectives on their perceived benefits of hypertension and diabetes medications and determine associations between perceived benefits and demographics, adherence, and disease control.

Methods:

We interviewed 60 adults with type 2 diabetes and hypertension on oral medications. Participants were asked what benefits they expected from taking their medications. Transcripts were analyzed using a modified template approach. Benefits were categorized into short-term, long-term, or misconceptions (e.g. “medications cure diabetes”). Associations between perceived benefits and demographics, adherence, hemoglobin A1c, and blood pressure were analyzed.

Results:

In general, participants had relatively high self-reported medication adherence and well-controlled disease. All participants identified benefits of their hypertension medications; however, only 85% identified benefits of their diabetes medications. Half described only short-term benefits (e.g. lower blood sugar) (48%); almost one-third described both short- and long-term benefits (e.g. prevent complications) (30% and 28%, respectively). In multivariate analysis, participants with higher comorbidity were more likely to name long-term benefits of hypertension medications (odds ratio 13.3 (1.8–97.8), p = 0.01).

Discussion:

Participants perceived short-term benefits of hypertension and diabetes medications more often than long-term benefits; participants with higher comorbidity identified more long-term benefits. Further studies are warranted to determine whether additional education on long-term benefits may improve adherence.
‘Commensality’ as a theatre for witnessing change for criminalised individuals working at a resettlement scheme
Authors: Parsons Julie M
Published: December 2018

This article draws on analysis of interview data from an exploratory case study at an independent ‘offender’ resettlement scheme in England, investigating the benefits or otherwise of commensality for criminalised individuals and the wider community who share a communal lunchtime meal. For prisoners released on temporary licence and others referred through probation, caught in the liminal space between criminal and civilian life, commensality enables social interaction with non-criminalised individuals in a social environment outside of the prison estate. It becomes an arena for the display of non-criminalised identities in preparation for release into the community after punishment. It is a useful tool for social integration that challenges stereotypical beliefs about criminalised individuals amongst the wider community. Moreover, commensality works as a theatre for the performance of non-criminalised identities, by promoting social inclusion and generativity, it is part of a process of desistance geared towards improving self-worth.

Authors: Inayat Faisal , Munir Ahmed , Wahab Ahsan , Younus Fariha , Zafar Fahad , Ullah Waqas
Published: December 2018

Primary esophageal diffuse large B-cell lymphoma (DLBCL) is an extremely rare clinicopathologic entity. We report one case from our clinical experience and undertake a review of the previously published cases. A systematic literature search of the medical databases PubMed and Google Scholar was conducted. A total of 15 cases fulfilled the inclusion criteria. The data on patients’ characteristics, epidemiology, clinical features, HIV status, gross appearance of the lesion, esophageal location, treatment, and outcome were collected and analyzed. Primary esophageal DLBCL was more common among males, primarily in the fifth and sixth decades of life. Dysphagia was the most common initial clinical presentation. Tissue biopsy with immunohistochemistry was an indispensable diagnostic modality. The mainstay of treatment was chemotherapy with cyclophosphamide, vincristine, doxorubicin, and prednisone regimen, in addition to anti-CD20 antibody rituximab, with or without radiotherapy. This review serves to outline our current understanding of the epidemiology of and risk factors for primary esophageal DLBCL, the pathophysiology of this disorder, and currently available approaches to diagnosis and management.
Variation among Argentinean Orthopedics Surgeons in the Indications in Rotator Cuff Lesions
Authors: Robles Cristian , Aguirre Gerardo , Cristiani Mauro , Bertiche Pablo , Lobos Esteban , Allende Christian
Published: December 2018

Introduction:

Indications in the treatment of rotator cuff lesions are widely discussed and not standardized. The aim of this study is to evaluate the variability among Argentinean orthopedic surgeons regarding the indications of treatment in different rotator cuff lesions.

Methods:

A questionnaire was designed based on the study carried out by Dunn et al. (JBJS Am 2005). Its aim was to gather the opinion of Argentine orthopedic surgeons on decision making concerning different rotator cuff lesions. Surgeons were divided into general orthopedic surgeons or shoulder specialists according to the number of shoulders treated surgically in the last year. The questionnaire has two sections: four hypothetical clinical cases and 11 questions about factors that could influence treatment selection.

Results:

Out of 556 questionnaires sent, 162 were completed, 117 by orthopedic surgeons and 45 by shoulder specialists. The specialists reported mostly arthroscopic repairs (57%), orthopedic surgeons reported repairing these lesions mainly by mini open or open technique (48% and 21% respectively). The highest agreement between both groups was evidenced in case number 1 (traumatic partial injuries in young patients (70% in favor of rotator cuff repair)). There was also agreement in the contraindication of the use of corticosteroids before surgery (p = 0.74), and in the repair of rotator cuff as a factor to prevent osteoarthritis (p = 0.27). Rotator cuff repair failure rate was considered to be 20%, not evidencing differences between groups.

Conclusions:

This study evidences the variation in indications between Argentinean surgeons in the treatment of rotator cuff lesions. The variability in the management of these patients, makes it difficult to establish protocols of treatment, or consensus guidelines to help standardize treatments for these injuries

Authors: Гарнов Андрей , Garnov Andrey , Одегов Юрий , Odyegov YUriy
Published: December 2018

The article examines the characteristics of employment and unemployment in the labor markets of single-industry towns. The authors consider the forms of employment and unemployment, give their detailed description. The analysis of the legislative base, strategic and program documents in the field of employment of the company towns has been carried out. An assessment was made of the effectiveness of government measures aimed at creating the necessary conditions for reducing various types of unemployment in single-industry towns. It is concluded that, despite the decrease in registered unemployment, the problem of employment of the population of single-industry towns has not yet been resolved. The number of people employed in mono-cities is decreasing, of which the outflow of the able-bodied population continues. Working conditions in single-industry towns are worsening, and a significant proportion of the labor force is informally employed or informally unemployed. The authors propose to develop a policy of employment management in single-industry towns, taking into account the existence of hidden unemployment, and include in it a set of measures aimed at solving the problems of self-employment of the population.

Published: December 2018

The loci (L) equally spaced from a sphere and a straight line, and from a conic surface and a plane, are considered. The following options have been considered. The straight line passes through the center of the sphere (a = 0), at the same time completely at spheres’ positive radiuses a surface of rotation is obtained, forming which the parabola is, and a rotation axis – this straight line. The parabola’s top forms the biggest parallel on the site points of intersection of the parabola’s forming with the rotation axis. Let's call such paraboloid a perpendicular paraboloid of rotation. The straight line crosses the sphere, but does not pass through the center (0 < a < R/2) – a perpendicular paraboloid, at that the surface is also completely obtained at radiuses’ positive values. The straight line is tangent to the sphere (a = R/2) – a surface which projections are parabolas, lemniscates and circles, and a piece from a tangency point to the sphere center – at radiuses positive values; a beam from the sphere center, perpendicular to this straight line – at radiuses negative values, at that the beam and the piece belong to one straight line. The straight line lies out of the sphere (α > R/2) – two different surfaces, having the general properties with a hyperbolic paraboloid, are obtained, one of which is obtained at radius positive values, and another one – at radius negative values. It has been noticed that loci, equally spaced from a sphere and a straight line, and from a cylinder and a point, coincide at equal radiuses and distances from axes to points and straight lines if to take into account the surfaces obtained both at positive, and negative values of radiuses. Locus, equally spaced from the conic surface of rotation and the plane, are two elliptic conic surfaces which in case 7.4.1 degenerate in the conic surfaces of rotation. In cases 7.4.3 and 7.4.4 one elliptic conic surface degenerates in a plane and a parabolic cylinder respectively.

Previously, the method of rotating of flat geometric objects around curvilinear axes was described by us. The next step in the path of our research should be the development of methods for the automated creation of surfaces digital models obtained by the described rotation method. We have created models of surfaces, the axis and the forming curve of which are circles lying in the same plane. Several cases of mutual disposition for such circles were analyzed. Modeling was carried out using constructive techniques. Surfaces were created using the “surface by section” operation. The centers of such circular sections belong to the axis of rotation, if it is a circle. Using the special tools incorporated in the KOMPAS-3D program, we have cut the surfaces modeled in this way by planes, and obtained a number of flat sections. Taking into account the difficulties occurring during the study of such complex geometric objects by means of flat graphic constructions, as well as graphic computer modeling, we have realized the need to create a mathematical apparatus describing these objects’ shape. The required mechanism should be applicable to any pair of second-order curves interconnected as “axis — generatix”. We have considered an elementary example – the rotation of a point around a curve elliptical axis. In this paper a solution for the problem of finding a system of equations describing a set of point positions, which it will successively take when rotating around the elliptic axis, is presented. It is possible to apply a similar mathematical apparatus to axes having the form of other quadrics, for example, hyperbolas or parabolas, as well as to generatices consisting of more than one point, that is, to forming curves.
Competence Approach in Teaching the Topic "Tangent Plane and Normal"

Qualified presentation of the topic "Tangent Plane and Surface Normal" in terms of competence approach is possible with the proper level for students' attention focusing on both intra-subject and inter-subject relations of descriptive geometry. Intra-subject connections follow from the position that the contingence is a particular (limit) case of intersection. Therefore, the line of intersection of the tangent plane and the surface, or two touching surfaces, has a special point at the tangency point. It is known from differential geometry [1] that this point can be nodal, return, or isolated one. In turn, this point’s appearance depends on differential properties of the surface(s) in this point’s vicinity. That's why, for the competent solution of the considered positional problem account must be also taken of the inter-subject connections for descriptive and differential geometry. In the training courses of descriptive geometry tangent planes are built only to the simplest surfaces, containing, as a rule, the frames of straight lines and circles. Therefore, the tangent plane is defined by two tangents drawn at the tangency point to two such lines. In engineering practice, as such lines are used cross-sections a surface by planes parallel to any two coordinate planes. That is, from the standpoints for the course of higher mathematics, the problem is reduced to calculation for partial derivatives. Although this topic is studied after the course of descriptive geometry, it seems possible to give geometric explanation for computation of partial derivatives in a nutshell. It also seems that the study of this topic will be stimulated by a story about engineering problems, which solution is based on construction of the tangent plane and the normal to the technical surface. In this paper has been presented an example for the use of surface curvature lines for programming of milling processing for 3D-harness surfaces.

By the term functional food we mean food, processed or not, which on the basis of scientific studies can contribute to the achievement of specific operational objectives within the human body and play an important role in the direction of prevention degenerative diseases and health promotion. The possible beneficial properties of functional foods are due to their content in bioactive ingredients, with specific biological properties and effects within the human body. Some examples of processed functional foods are calcium - enriched milk, enriched juices with ω-3 fatty acids, yoghurt with probiotic organisms and phytosterol-enriched margarines. At the same time, constantly new scientific findings confirm the potential beneficial properties of different conventional food, such as tea, blueberries, pomegranate,berries, hippophaes and many others, which are known by the term "superfoods". Recently, the appearance of a multitude of chronic degenerative diseases such as cardiovascular disease, diabetes, obesity, osteoporosis and cancer, has led to ways of defending human health through the adoption of appropriate dietary patterns. Hence, functional foods, provided that they fit inside hygiene and balanced nutrition, are suggested as a potential solution tore inforcing the prevention strategy, avoiding the need for therapy, with the aim of promoting the health of the population. This is the reason why there is an ever-increasing trend particularly in Europe and USA. Also, improved accessibility knowledge and information from consumers, promotes an increased search for information about their beneficial properties.
Dietary and Lifestyle Risk Factors and Metabolic Syndrome: Literature Review

Metabolic syndrome (MetS) is considered a threat to public health due to its rapid growing prevalence worldwide. MetS can result from interrelated metabolic abnormalities including insulin resistance (IR), hypertension, dyslipidemia, and abdominal adiposity. Although the pathogenesis of this syndrome is not distinctly understood, it is strongly influenced by multiple genetic variations that interact with many environmental factors such as positive family history of MetS, adherence to unhealthy dietary patterns, low physical activity and smoking and that explain the variations in the prevalence of the MetS within and across populations. All of these factors were found to be associated with IR, obesity, and triglycerides elevation which therefore increase the risk of the MetS Several studies highlighted the effective preventive approach includes lifestyle changes, primarily losing weight, adopting healthy diet, and practicing exercise. All of the mentioned factors can reduce the risk of MetS.
