Published: September 2018

Improving extinction learning is essential to optimize psychotherapy for persistent fear-related disorders. In two independent studies (bothn= 24), we found that goal-directed eye movements activate a dorsal frontoparietal network and transiently deactivate the amygdala (ηp2= 0.17). Connectivity analyses revealed that this downregulation potentially engages a ventromedial prefrontal pathway known to be involved in cognitive regulation of emotion. Critically, when eye movements followed memory reactivation during extinction learning, it reduced spontaneous fear recovery 24 h later (ηp2= 0.21). Stronger amygdala deactivation furthermore predicted a stronger reduction in subsequent fear recovery after reinstatement (r= 0.39). In conclusion, we show that extinction learning can be improved with a noninvasive eye-movement intervention that triggers a transient suppression of the amygdala. Our finding that another task which taxes working memory leads to a similar amygdala suppression furthermore indicates that this effect is likely not specific to eye movements, which is in line with a large body of behavioral studies. This study contributes to the understanding of a widely used treatment for traumatic symptoms by providing a parsimonious account for how working-memory tasks and goal-directed eye movements can enhance extinction-based psychotherapy, namely through neural circuits (e.g., amygdala deactivation) similar to those that support cognitive control of emotion.

SIGNIFICANCE STATEMENTFear-related disorders represent a significant burden on individual sufferers and society. There is a high need to optimize treatment, in particular via noninvasive means. One potentially effective intervention is execution of eye movements following trauma recall. However, a neurobiological understanding of how eye movements reduce traumatic symptoms is lacking. We demonstrate that goal-directed eye-movements, like working-memory tasks, deactivate the amygdala, the core neural substrate of fear learning. Effective connectivity analyses revealed amygdala deactivation potentially engaged dorsolateral and ventromedial prefrontal pathways. When applied during safety learning, this deactivation predicts a reduction in later fear recovery. These findings provide a parsimonious and mechanistic account of how behavioral manipulations taxing working memory and suppressing amygdala activity can alter retention of emotional memories.
Otubain 1: a non-canonical deubiquitinase with an emerging role in cancer

Published: September 2018

The ubiquitin system regulates diverse biological processes, many involved in cancer pathogenesis, by altering the ubiquitination state of protein substrates. This is accomplished by ubiquitin ligases and deubiquitinases (DUBs), which respectively add or remove ubiquitin from substrates to alter their stability, activity, localization and interactions. While lack of catalytic activity makes therapeutic targeting of ubiquitin ligases difficult, DUB inhibitors represent an active area of research and the identification of cancer-associated DUBs may lead to the development of novel therapeutics. A growing body of literature demonstrates that the DUB Otubain 1 (OTUB1) regulates many cancer-associated signaling pathways including MAPK, ERa, epithelial-mesenchymal transition (EMT), RHOa, mTORC1, FOXM1 and P53 to promote tumor cell survival, proliferation, invasiveness and therapeutic resistance. In addition, clinical studies have associated elevated OTUB1 expression with high grade, invasiveness and metastasis in several tumor types including lung, breast, ovarian, glioma, colon and gastric. Interestingly, in addition to catalytic DUB activity, OTUB1 displays a catalytic-independent, non-canonical activity where it inhibits the transfer of ubiquitin onto protein substrates by sequestration of E2 ubiquitin-conjugating enzymes. The aim of this review is to describe the canonical and non-canonical activities of OTUB1, summarize roles for OTUB1 in cancer-associated pathways and discuss its potential therapeutic targeting.

Published: September 2018

Background and aims: Arteriovenous fistula (AVF) maturation failure rates remain high in patients with end-stage renal disease (ESRD). Although preoperative morphological and functional assessment of blood vessels by duplex ultrasonography (DUS) has been shown to improve AVF maturation, there is no consensus regarding the optimal vein (VD) and artery (AD) diameters to be universally used for AVF creation. To improve patient selection, set out to investigate if there is a correlation between preoperative VD/AD and clinical covariates, and postoperative AVF outcome.Methods: This was a prospective cohort study conducted during January–August 2014. ESRD patients referred to “Niculae Stăncioiu” Heart Institute Cluj-Napoca, who had a VD ≥1.9 mm and AD ≥1.5 mm, as measured by DUS, and underwent AVF creation were enrolled. We assessed whether preoperative VD/AD and clinical covariates were associated with AVF maturation rate and primary patency at 2 years after AVF creation.Results: Of 115 patients referred for AVF creation, 93 were included in the study. Mean (± standard deviation) VD was 3.3 ± 1.1 mm and VDs were distributed in quartile Q1 <2.55 mm, Q2: 2.56-3.10 mm, Q3: 3.11-3.70 mm and Q4: >3.71 mm. Mean AD was 3.3 ± 1.4 mm and ADs were distributed in Q1 <2.55 mm, Q2: 2.56-3.10 mm, Q3: 3.11-3.70 mm, and Q4, >3.71 mm. AVF maturation rate increased proportionally with VD from Q1 (62%) to Q2 (70%), Q3 (82%) to Q4 (96%) (p=0.03). Based on AD, a higher AVF maturation rate was observed in Q3 (86%), Q4 (83%) vs Q1 (71%) and Q2 (67%). Long-term primary patency of AVFs seemed not to be influenced by VD and AD. In older patients and those with peripheral arterial disease, AVF maturation failure tended to be higher.Conclusions: Our findings suggest that a preoperative VD ≥1.9 mm and AD ≥1.5 mm have a successful maturation rate of AVF greater than 60% in ESRD patients. The maturation rate of surgical AVF increases proportionally with the size of VD used for AVF creation.

Published: September 2018

ABSTRACT Objective: to identify socio-demographic, clinical and psychological predictors of well-being and quality of life in men who underwent radical prostatectomy, in a 360-day follow-up. Method: longitudinal study with 120 men who underwent radical prostatectomy. Questionnaires were used for characterization and clinical evaluation of the participant, as well as the instruments Visual Analog Scale for Pain, The Ways of Coping Questionnaire, Hospital Depression and Anxiety Scale, Satisfaction with Social Support Scale, Marital Satisfaction Scale, Subjective Well-Being Scale and Expanded Prostate Cancer Index. For data analysis, the linear mixed-effects model was used. Results: the socio-demographic factors age and race were not predictors of the dependent variables; time of surgery, problem-focused coping, and anxiety were predictors of subjective well-being; pain, anxiety and depression were negative predictors of quality of life; emotion-focused coping was a positive predictor. Marital dissatisfaction was a predictor of both variables. Conclusion: predictor variables found were different from the literature: desire for changes in marital relationship presented a positive association with quality of life and well-being; emotion-focused coping was a predictor of quality of life; and anxiety was a predictor of subjective well-being.

ABSTRACT Objective: to analyze the evidence available in the literature on the alterations in the sexuality of candidates and recipients of liver transplantation. Method: integrative review of the literature with search for primary studies in the databases MEDLINE (via PUBMED), CINAHL e LILACS, published in English, Portuguese and Spanish. Results: the 16 primary studies included were grouped into three categories: 1) female sexuality (n=5), 2) male sexuality (n=5) and 3) male and female sexuality (n=6). In category 1, the subjects investigated were contraception, pregnancy, sexual dysfunction, presence of gynecological symptoms and sexually transmitted infections. In category 2, the main focus of the studies was erectile dysfunction, sexual desire and satisfaction, and consequences of the immunosuppressive regimen with mycophenolic acid in men. In category 3, the evaluation of sexual function was the main topic. Conclusion: the scientific evidence generated provides support to encourage health professionals to incorporate the topic of sexuality in the routine of care. Knowledge gaps were identified and new studies should be conducted in order to implement interventions to prevent, minimize and/or control changes related to the patient’s sexuality.

Resumo Este artigo reflete sobre as formas de organização de um grupo de extrativistas em vista da implementação de um termo de uso como forma de regulamentar o extrativismo de balata (Manilkara bidentata) na Floresta Estadual (FLOTA) do Paru, no Pará. Trata-se de reflexões construídas no âmbito de projetos de pesquisa e de extensão universitária, que, por meio da observação participante, têm propiciado contatos regulares com os sujeitos envolvidos no caso. O local de estudo é o município de Monte Alegre, em cujo território a FLOTA Paru abriga sete unidades de manejo florestal, destinadas a concessões florestais, nos moldes da lei de gestão de florestas públicas. É também com base nesta lei, e no decreto que regulamenta seus dispositivos que o termo de uso foi apresentado pelo Estado aos balateiros como condição para a continuidade de seu ofício tradicional dentro da referida Unidade de Conservação. A implementação desse instrumento, contudo, depara-se com desafios e questões que sugerem a sua inadequação às características socioculturais do grupo interessado, no que se refere às relações mantidas por este grupo com o Estado.
Conhecimento ecológico tradicional da ictiofauna pelos quilombolas no Alto Guaporé, Mato Grosso, Amazônia meridional, Brasil

Published: September 2018

Resumo O objetivo desta pesquisa foi estudar o conhecimento ecológico tradicional (CET) relacionado à pesca feita por grupo étnico autoidentificado como quilombola, por meio da análise de fatores que influenciam o consenso cultural e as técnicas da pesca artesanal. Participaram 24 homens e sete mulheres dos quilombos Retiro, Boqueirão, Casalvasco e Manga. Os métodos de amostragem utilizados foram: bola de neve, lista livre e observação participante. Os resultados incluem 47 etnoespécies (46 peixes e um réptil). O consenso cultural é composto por: Hoplias malabaricus, Cichla sp., Pseudoplatystoma fasciatum, Astronotus ocellatus, Satanoperca pappaterra, Brycon cephalus, Piaractus mesopotamicus, P. corruscans, Pimelodus sp., Colossoma macropomum, Pygocentrus nattereri, Mylossoma aureum, Astyanax sp. e Leporinus freiderici. Embora tenha sido maior a riqueza do conhecimento entre pessoas que residiram temporariamente em outros estados brasileiros, este aspecto não esteve relacionado à idade dos entrevistados. A manutenção e a transmissão de CET é propiciada por contato diário com peixes e com o rio desde criança, bem como por observação das práticas de pesca em grupo. O CET é parte da identidade e representa uma herança cultural que deve ser valorizada. É necessária a participação desses atores sociais nos planos de decisão e de gerenciamento de áreas protegidas.

THE MEDIATING ROLE OF VIRTUOUSNESS IN HUMAN RESOURCE MANAGEMENT AND JOB OUTCOMES
Authors: PIRES MARIA LEONOR , NUNES FRANCISCO
Published: September 2018

ABSTRACT In this study, we explore the role of organizational virtuousness (OV) as a mechanism through which human resource management practices (HRMPs) affect employee outcomes. We propose that HRMPs lead to higher levels of organizational citizenship behaviors and affective commitment by stimulating OV. Using a sample of 525 workers, from 22 stores of a retailing company, we found evidence that HRMPs predict OV, thereby predicting members’ citizenship behaviors and affective commitment. By suggesting this new mediator, this study contributes to a better understanding of the causal chain linking HRMPs and performance.
THE ROLE OF PERCEIVED ORGANIZATIONAL SUPPORT IN JOB INSECURITY AND PERFORMANCE

Published: September 2018

ABSTRACT In this study, we develop a conceptual model of the relationship between job insecurity and job performance, which is mediated by affective organizational commitment and moderated via perceived organizational support in a Chilean company that has undergone downsizing. In this cross-sectional study, we focused on 400 Chilean employees from the retail sector. Our findings indicate that job insecurity negatively influences job performance, which is a relationship that is partially mediated by effective organizational commitment. Moreover, a high level of perceived organizational support helped intensify the effects of the relationship between job insecurity and affective organizational commitment. To minimize the negative effects of job insecurity on the active employees of a downsizing strategy, an effective intervention is required by developing a more realistic communication in terms of a worker's expectations toward the organization.

Published: September 2018

ABSTRACT: This research aimed at evaluating the effect of increasing coexistence periods with weeds on the nutritional components of the forage grass Brachiaria brizantha cv. Marandú under pasture renewal conditions. The experiment was arranged in randomized blocks with four replications, and treatments were represented by eight coexistence periods, namely: 0, 15, 30, 45, 60, 75, 90 and 120 days after seedling emergence. A phytosociologic evaluation was performed on the weed community at the end of the coexistence periods; later, weeds were eliminated by an herbicide formulated with aminopyralid+2,4-D (40+320 g L-1) at 2.5 L ha-1, applied in post-emergence. The fodder plants were evaluated at the end of the experimental period as for leaf-stem ratio, volumetric density of green leaf, volumetric density of total dry matter and main nutritional components, including: crude protein, neutral detergent fiber, ether extract, organic matter and mineral matter, and from this, the total carbohydrate content was calculated. The presence of weeds altered the pasture structure, since it affected negatively the leaf/stem ratio and the volumetric leaf density of B. brizantha. The coexistence also reduced the nutritional components of B. brizantha and determined that control measures should be adopted before reaching 30 days of coexistence between fodder plants and weeds.

Bank Holdings and Systemic Risk
Authors: Brunetti Celso , Harris Jeffrey H. , Mankad Shawn
Published: September 2018

The recent financial crisis has focused attention on identifying and measuring systemic risk. In this paper, we propose a novel approach to estimate the portfolio composition of banks as function of daily interbank trades and stock returns. While banks’ assets are reported to regulators and/or the public at relatively low frequencies (e.g. quarterly or annually), our approach estimates bank asset holdings at higher frequencies which allows us to derive precise estimates of (i) portfolio concentration within each bank—a measure of diversification—and (ii) common holdings across banks—a measure of market susceptibility to propagating shocks. We find evidence that systemic risk measures derived from our approach lead, in a forecasting sense, several commonly used systemic risk indicators.
CREATION OF COMPOSITE BRONZES REINFORCED BY STEEL DENDRITES
Authors: Potekhin B. A. , Khristolyubov A. S. , Zhilyakov A. Yu.
Published: September 2018

The paper studies the group of composite bronzes, BrFNCA 9-4-1-1, BrFNA 12-7-1 and others where brittle Cu3Sn intermetallics are «replaced» by steel dendrites. The mass transfer of Fe, Ni, Co, Al between the matrix and dendrites in these bronzes is investigated. Dendrite dispersion depending on the methods used to produce these bronzes can be increased by a factor of 10, for example, in the vacuum casting process. The mechanical properties of BrFNCA samples (σв = 372 МPа, δ = 25 %, ψ = 42 %) are higher as compared with the BrO10 prototype: by 50 % in terms of σв hardness, and by 4–5 times in terms of δ and ψ plasticity. The coefficient of friction is lower than that of BrO10 by 20–30 %, and wear resistance is higher by an order of magnitude. The fact of a significant effect of the dendritic component dispersion on the BrFNA bronze wear rate is found. Thus, the wear rate for 1 μm and 10 μm dendrite cross sections is 0,002 and 0,025, respectively, and the coefficient of friction remains unchanged, i.e. it does not depend on dendrite dispersion. The whole set of mechanical, processing and service properties makes it possible to consider that the semicommercial tests of this new class of BrFNCA composite bronzes reinforced with H12C7A maraging dendrites for sliding friction units are justified and promising.

Avrupa Birliği (AB) enerji politikalarına, birliğin temelini oluşturan

1951 tarihli Paris antlaşmasıyla birlikte başlamış, süreç içerisinde de amaç ve

ilkelerinde büyük sapmalar göstermemiştir. Günümüzde ise AB’nin nükleer

enerjiden yenilenebilir enerjiye doğru geçiş yapan politikaları benimsediği

görülmektedir. Türkiye ise hızla artan nüfus, yükselen elektrik ihtiyacı,

sürekli büyümenin elektrik tüketimini arttırması, enerjideki yüksek dışa

A Secure Protocol for Exchanging Cards in P2P Trading Card Games Based on Transferable e-cash
Authors: Silva Marcos , Junior Marcos
Published: September 2018

Trading card games (TCG) distinguish from traditional card games mainly because the cards are not shared between players in a match. Instead, users play with the cards they own (e.g., purchased or traded with other players), which corresponds to a subset of all cards produced by the game provider. Even though most computer-based TCGs rely on a trusted third-party (TTP) for preventing cheating during trades, allowing them to securely do so without such entity remains a challenging task. Actually, potential solutions are related to e-cash protocols, but, unlike the latter, TCGs require users to play with the cards under their possession, not only to be able to pass those cards over. In this work, we present the security requirements of TCGs and how they relate to e-cash. We then propose a concrete, TTP-free protocol for anonymously trading cards, using as basis a secure transferable e-cash protocol.
Probing the distant galaxy cluster JKCS 041 on the L − T − M scaling relations
Authors:   University of Waterloo, Waterloo, Canada, Babyk Iu. V.
Published: September 2018

The detailed X-ray analysis of the distant galaxy cluster JKCS 041 is presented. We use deep (~75 ks) archived data of X-ray Chandra Observatory to extract the main physical characteristic for one of the most distant galaxy cluster known to date. We investigate the imaging and spectral properties of JKCS 041. We explore its surface brightness, density, entropy, cooling time, and mass profiles. The temperature of JKCS 041 is equal to 7.4 ± 2.9 keV while the total virial mass is M200 = (4.6 ± 2.9) × 1014MSun. The gas fraction is ~10% while the dark matter is ~90% at R200.

We use the obtained physical parameters of JKCS 041 to build numerous X-ray scaling relations. By adding JKCS 041 parameters we increase the redshift of our previous cluster’s sample from 1.4 to 1.8. We study the three classical relations between temperature, luminosity and total mass, and two additional. We find the concentration parameter of JKCS 041, build c − M relation and compare them with current hydrodynamic simulations. In addition, we explore, for the first time in the case of distant objects, the M − Y = T · Mg relation which is one of the most robust mass estimators. We conclude that concentration parameter, c, of JKCS 041 is in a good agreement with theoretical predictions. The obtained X-ray scaling relations were used to probe their evolution. We find that our results show inconsistent with self-similar evolution models.

Using the equation of state of electron-nuclear model at high densities and the mechanical equilibrium equation we have investigated the influence of interparticle interactions and axial rotation on the macroscopic characteristics of massive white dwarfs. The method of solving the equilibrium equation in the case of rotation, using the basis of universal functions of the radial variable has been proposed. The conditions in which the axial rotation can compensate for weight loss of mass due to the interparticle Coulomb interactions have been established.
A NOÇÃO DE DIREITO NO PROCESSO CIVILIZATÓRIO: UMA RELAÇÃO DE PODER E NEGAÇÃO DO CONTRATO SOCIAL DE ROUSSEAU
Authors: Ferro Rodrigo Rage , Carnio Henrique Garbellini
Published: September 2018

O problema que se perscrute nesse artigo é refletir se a base da legitimidade estatal residiria na figura de um contrato social, como explicita a famosa Teoria do Contrato Social de Rousseau. Tal assertiva, contudo, entra em conflito com o fato de o direito, como uma criação humana, ser fruto de um processo civilizatório marcado pela barbárie e pelo castigo, portanto por critérios totalitários, e com a própria concepção normativa que está no próprio homem e que não permite que o direito se mantenha livre dessa influência. Isso vai em direção oposta ao surgimento de um Estado com base em um acordo voluntário de indivíduos, o que, per se, justifica cientificamente esta análise pormenorizada e onde reside sua relevância social. Cabe este artigo, como principal objetivo, baseado em um processo metodológico e sistemático de investigação com contribuições teóricas de Freud, Nietzsche e Kelsen, mostrar que a noção de direito promoveu o processo civilizatório com base em relações de poder, domínio e força de forma que não se coaduna com uma gênese da força normativa com base na teoria do contrato social de Rousseau. Chegou-se a esse resultado, com base em uma visão histórico-pragmática, a partir da reflexão desses filósofos sobre a história da humanidade e o próprio entendimento dos autores desse artigo sobre a relação entre a noção de direito e a evolução do processo civilizatório.
Audio Description: Turning Access to Film into Cinema Art
Authors: Thompson Hannah
Published: September 2018

This article reads Jacques Derrida's notion of the "supplement" alongside Georgina Kleege's influential work on blind access to the visual arts, in order to argue that audio description (AD) should be repositioned as a key cinematic feature rather than an access-driven afterthought. Analysis of instances of extradiegetic and intradiegetic audio description in films featuring blind protagonists reveals that AD can function to comment on, replicate or foreground the experience of the blind protagonist and/or the blind beholder. The most successful descriptions are those which are incorporated into the film from its inception, and which thus allow an enhanced viewing experience for both blind and non-blind filmgoers.
Social Value Creation and Impact Measurement : What Do They Mean Exactly?
Authors: Krátki Noémi , Szabó Roland Z.
Published: September 2018

There is a strong need for social value creation in our life. More and more people have to face mental illness caused by our stressful life. Social entrepreneurship and social enterprises are approaches to deal with these challenges. They are managed with a business mind-set coupled with social sensitivity. The paper examines how social value creation is interpreted and how social impact is measured and reported by social entrepreneurs using multiple cases from the business and the public sphere. It was found that a comprehensive social value creation model could help social enterprises to manage these challenges and have a greater impact.
The Effects of Hofstede’s Cultural Dimensions on Pro-Environmental Behaviour: How Culture Influences Environmentally Conscious Behaviour
Authors: Nagy Szabolcs , Konyha Molnárné Csilla
Published: September 2018

The need for a more sustainable lifestyle is a key focus for several countries. Using a questionnaire survey conducted in Hungary, this paper examines how culture influences environmentally conscious behaviour. Having investigated the direct impact of Hofstede’s cultural dimensions on pro-environmental behaviour, we found that the culture of a country hardly affects actual environmentally conscious behaviour. The findings indicate that only individualism and power distance have a significant but weak negative impact on pro-environmental behaviour. Based on the findings, we can state that a positive change in culture is a necessary but not sufficient condition for making a country greener.

An assessment of vertigo patients presenting to the otorhinolaryngology and neurology outpatient clinics
Authors: Sarıca Selman , İnanç Yılmaz , İnanç Yusuf
Published: September 2018

Objective: Vertigo
is a general term used for disorientation and is a frequent cause of admission
to emergency services, otorhinolaryngology and neurology outpatient clinics. This
study aims to evaluate the clinical findings, diagnostic laboratory tests,
brain magnetic resonance imaging, and Doppler ultrasonography results of
patients with complaints of vertigo. Methods: Patients
aged >18 years who admitted to the Otorhinolaryngology and Neurology Outpatient
clinics of Kahramanmaraş Sütçü İmam University Training and Research Hospital
with the main complaint of vertigo between January 2017 and August 2017 were
retrospectively reviewed. The patients were evaluated in respect of anamnesis,
examination findings, and diagnostic tests (pure tone audiometry, video
nystagmography, brain magnetic resonance imaging, and carotid and vertebral
artery Doppler ultrasonography). Results: The study
included a total of 101 patients with a mean age of 46.36 ± 16.1 years who
presented with the complaint of vertigo. Of the patients, 16 had an ischemic
gliotic region, 4 had a lacunar infarct, 2 had an arachnoid cyst, 2 had a
cerebellar infarct, 1 had a meningioma, and 1 had a pineal gland cyst on the
brain magnetic resonance imaging. Of the patients evaluated in the
Otorhinolaryngology outpatient clinic, 87 (86.13%) were diagnosed with
peripheral vertigo and 14 (13.6%) with central vertigo. A diagnosis of central vertigo
was made in 23 (22.77%) patients evaluated in the Neurology outpatient clinic.

Conclusions: For
patients presenting with the complaint of vertigo to the otorhinolaryngology
and neurology outpatient clinics, a detailed anamnesis and a physical
examination precede specific vestibular tests in the diagnosis. A coordinated
communication of both clinics is important for a rapid diagnosis and prevention
of unnecessary examinations.
The Problem of Ontological Insecurity. What Can We Learn from Sociology Today? Some Zen Buddhist Inspirations
Authors: Konecki Krzysztof T.
Published: September 2018

Can we learn about the art of living from sociology? Sociology teaches us that we are the part of a broader group called society. We are taught that society should be first described in order to be understood and/or explained, and that the cognitive function is the most important part in understanding the role sociology should play in a democratic and modern society. Is this understanding (cognition) enough? What more can we get to better our quality of life and live a wholesome life from studying sociology or society using a sociological perspective? Is sociology a tool for the art of living or is it just a play of the “sophisticated”? In this paper, we analyze the sociology from the philosophy of Zen Buddhism to show the connection between the work of mind and the sociological concepts that are used to analyze “society.” Moreover, we analyze the approaches of George H. Mead, Robert Merton, and especially and separately Anthony Giddens that created, very important for our considerations, the concept of “ontological security.” We also reconstruct the structural conditions of the art of living and happiness, analyzing the concept of greedy institutions by Lewis Coser. We analytically connect the structural conditions of work in contemporary greedy institutions (working on projects) with the loss of ontological security. We analyze the displacement of the meaning of work, career, autonomy, time structure, identity, privacy and happiness, and finally the sociology. We try to use a Buddhist inspiration to analyze issues of suffering and, associated with it, so called ontological insecurity and the welfare of the individual and/or society.
A Healthy Mind in a Healthy Body—Recipes for a Healthy Living as Seen in Polish Vlogs
Authors: Maj Agnieszka
Published: September 2018

The fashion for leading a healthy lifestyle has recently reached Polish society. Inspired by exposure through the mass media, many people have decided to introduce changes into the way they eat and exercise, primarily in order to become healthier and slimmer. According to recent surveys, one of the most popular sources of information concerning healthy lifestyles is, of course, the Internet. It is an extremely functional tool that allows its users not only the possibility to find the relevant information they need, but it also helps them create their own resources containing advice and information for other like-minded users. This article analyzes examples of Polish vlogs posted on the Youtube.pl platform that are principally devoted to improving fitness, as well as showing the most effective ways to lose weight. The four main areas of focus investigated are: the vloggers’ motivations for creating and publishing videos, the vloggers’ reference to their own bodies, the reasons they offer for seeking a healthier way of living, the vloggers’ bodies as their representation in the social space of the Internet, and the role of the Internet community in the many processes in helping people become slimmer.
Estrés Laboral Y Afectación Psico-Física En El Rendimiento Del Personal En Un Call Center Policial, Quito-Ecuador
Authors: Brito Pedro Flores , Rosero Shirley Fernanda , Reinoso Daniel Renato
Published: September 2018

The study investigates the various aspects of the perception of the health of call-center workers. This paper focuses on identifying the psychophysical affectation in the work performance of workers due to work stress from the foundation of preventive health. This, however, associated the relationship between the two variables to verify its affectation. Occupational stress influences the occurrence of psycho-physical alterations that affect work performance. This is attributed to the fact that it was found in the group investigated, which is composed of workers of the police operational management center of the metropolitan district of Quito (CGOP). The Maslach universal test that measures Burnout syndrome, emotional fatigue, depersonalization, and personal fulfillment were combined with attitude tests with Likert scales that measure the perception of those involved with their psychophysical affectation at their place of work. The results are evidenced, according to the Maslach test, in relation to the suffering of Burnout syndrome. The result shows that in this study, no worker meets the three conditions: emotional exhaustion (10.5%), depersonalization (22.2%), or realization personal (22.3%). However, they do meet one of the three areas individually. Associated with stress, physical-psychological affectations were identified, especially in the nervous system (1 in 10) and to a lesser extent in the digestive system. In conclusion, the results are mostly isolated because the study group performs frequent physical activity, which considerably diminishes the secondary and negative effects on their physical health.

L’architettura, in quanto bene d’uso, è da considerarsi come un’opera aperta, destinata a venire, nel corso della sua esistenza, modificata, trasformata, integrata per poter continuare ad essere utilizzata e fruita.Le architetture che sono state oggetto di dismissione, a seguito del venir meno delle motivazioni (funzioni) per le quali esse erano state realizzate, sono, più di altre, destinate a subire tali trasformazioni. Sono, infatti, architetture ormai deboli e fragili, nella maggior parte dei casi considerate prive di valore o quasi, che proprio in virtù di queste considerazioni vengono abbandonate e/o distrutte, decretandone irrimediabilmente la scomparsa.
