BODY AND BEAUTY AS FETISHISED COMMODITIES IN LOUIS DE BERNIÈRES’S NOVEL BIRDS WITHOUT WINGS
Authors: GOLBAN Tatiana , AKKAŞ Nuriye
Published: September 2020

This study attempts to reveal the concept of commodity fetishism, with its distinctly postmodern concern of body and beauty, as reflected in Louis de Berniéres’s novel Birds Without Wings. In his work, Berniéres tries to emphasise the material exorbitance of the body and reconsiders some master concepts of Marxist and Freudian discourse, such as fetish and commodity, with reference to use-value and exchange-value of the body and beauty. This study argues that Louis de Berniéres’s novel Birds Without Wings departs from both Marxist and Freudian representation of fetishism, and exhibits instead the social and discursive practices that encourage the fetishisation of objects, as well as the postmodern preoccupation with commodity-body-sign through the lenses of Jean Baudrillard. Louis de Bernières’s characters imagine that they can determine their own value in the world, as they are modern men, but they inevitably come to acknowledge that, as a result of modernity, their body and identity become enmeshed as signs in a symbolic exchange, their value being established by outer phenomena and not by themselves. In their plight for their own authority, these characters see only the annihilation of their assertions, since they become objectified in the political economy of signs, representing only symbolic or static beings whose worth is determined in the exchange process.

Changes in Motor Unit Number Estimate and Forced Vital Capacity as Predictors of ALS Progression
Authors: Olney Nicholas , Lomen Hoerth Catherine , Kohn Michael , Olney Richard
Published: September 2020

Background: An independent measure of lower motor neuron function that can be monitored over time is essential to evaluating the effect of drugs or stem cell transplantation and to determining prognosis in amyotrophic lateral sclerosis (ALS).  Longitudinal changes in forced vital capacity-percent of predicted (FVC%) and motor unit number estimate (MUNE) may identify patient groups with more rapid disease progression.

Objective: We attempted to define cutoff values for 3-month changes in FVC% and MUNE that identify ALS patients with rapidly progressive disease defined as survival of 30 months or less from symptom onset.

Design: Cohort study.

Subjects: We report data from 26 ALS patients, 10 patients reported previously and 16 patients not reported previously, except for the reproducibility of their MUNE data.

Results: Of the 26 patients, 7 had rapid progression.  Either a 40% decrease in statistical MUNE or a 20% decrease in FVC% over 3 months identified 6 of 7 rapid progressors (Sensitivity=86% 95% confidence interval [CI] 42.1% - 99.6%).  Of the 19 patients without rapid progression, 18 met neither the FVC or MUNE criterion (Specificity = 94.7% CI 95% 74.0% - 99.9%).  In a proportional hazards model, 3 month change in both FVC and MUNE were significantly predictive of decreased survival.

Conclusion: We suggest the use of a three-month change in MUNE or FVC% as a secondary enrollment criterion in therapeutic trials or to identify a subgroup of rapid progressors that may respond differently to treatments.

Authors: ŞAHİN BAL Sultan , DOGRU Mahmut
Published: September 2020

Soil radon gas measurements were made via a sensing system embedded in soil at radon monitoring station, which was established in Sivrice Fault Zone of Eastern Anatolia Fault Systems (DAFS) being one of the active fault system of Turkey. The occurrence times and magnitude of earthquakes at this zone were compared with the radon gas diffusion obtained online from the mentioned station and the results were interpreted in the light of data in the literature.

In this study, it was seen that there is a relationship between the changes in soil radon gas emission and earthquakes. Additionally, according to the analyses on graphs which present the changes in soil radon gas outlet taken from stations and earthquake lists taken from AFAD (Republic of Turkey Prime Ministry Disaster and Emergency Management Presidency), it was seen that almost all of the earthquakes occur in a decreasing period following the increase in radon emission.

WHEN BUREAUCRATS BECOME ACTIVISTS*
Authors: Vilaça Luiz
Published: September 2020

There is growing interest in how activist bureaucrats change policies; however, it remains unclear how bureaucrats become activists. This article develops a framework for the emergence of bureaucratic activism using the case of Brazilian prosecutors in the Belo Monte dam, a project that drew attention due to its social and environmental impacts. I show that two different types of prosecutors were involved in this case: activist prosecutors, who were committed to the proactive defense of affected communities, and conventional prosecutors, neutral agents that resorted to traditional tactics. Based on 82 interviews, document analysis, and participant observation, I argue that rather than being self-selected, prosecutors within conducive settings engaged in activism after they joined the state by developing long-term ties with local groups. By discovering the problems faced by affected communities and mediating their struggles with other policy actors, prosecutors internalized the grievances of these groups, building commitments to defend their causes.

Authors: Flanders Sean , Smith Natalie , Jones Charles , Greene Amanda
Published: September 2020

This case study analyzed the innovation processes that led to the adoption of a work-integrated learning program among several sport organizations. A comparative case study analysis was used to deduce the commonly shared determinants between each of the sport organizations. Notably, having an innovation champion was a key determination. As well, lack of resources regarding staffing, the involvement of the managers with the participating higher education institution, the ease of contract design, and access to good candidates for the program were also influential in the innovation process. This study revealed, for sport organizations facing similar issues, that the graduate apprenticeship program could provide benefits. As well for sport management program, it could provide a stronger relationship with regional sport organizations. This research also extends the body of research regarding the underlying mechanisms by which sport organizations innovate generally.

Published: September 2020

Proper ventilation is an important strategy in the practice of infection control. Hospitals are complex atmospheres that require ventilation for thermal comfort of patients as well as control of harmful pathogens infection emissions. The present study is performed on a hospital at Raipur (21.2514° N, 81.6296° E), India, to analyze the avoidance of airborne infections from the mouth of patient to protect the doctor and other patients in the intensive care unit (ICU) using Computational Fluid Dynamics (CFD) software FLUENT. Incense smoke is used to for capturing velocity field. Twenty seven (27) cases of simulation were executed using different air change per hour (ACH) (6, 9 & 12) and different inlet and outlet positions talking into account the constant inlet temperature (20 °C). The wall temperatures were taken out from ISHRAE handbook for Raipur region. The velocity vector and capturing the flow field were also performed experimentally. All three turbulence model (Standard, RNG & Realizable) predictions have shown to be in good agreement with the experimental data. It can be effectively employed to validate the extensively used k-ε model which was commonly used for ICU.
Institutes of thought - a new intellectual project
Authors: Akopova Tatyana S.
Published: September 2020

The article deals with current problems of innovative and prospective development of modern society, related to the formation of a new type of personality capable of self-determination in the conditions of a new technological order and the needs of humanitarization of social processes. The philosophical problem posed by science in ancient times - "what is a person" today is interpreted by social practice by the requirement to understand what is a thinking person, how ready he is to consciously perceive the world and himself in the world. the Demand for an intellectually developed person, a subject of social creativity with the ability to real thinking, a conscious approach to any situation, involves the creation of a new social space, in which various institutions of intellectual development are located - from traditional to new, initiative. The role of the entire educational system - from General to higher education-is growing, and it is becoming a leading factor and a promising process in creating new learning technologies and, above all, in teaching thinking. The obvious lag of education in solving this problem causes the intellectual elite to act ahead of time, interested in a new approach to the problem of creativity and thinking. This is evidenced by various associations, clubs, and unions formed locally, in professional communities, and in scientific circles that discuss and develop thinking technologies.

Published: September 2020

O mau gerenciamento, as mudanças nos parâmetros de consumo e a seca sujeitam muitas partes do mundo à sobrevivência diante da escassez de água potável e a qualidade da água potável precisa ser avaliada para um consumo adequado. A água dura pode levar ao acúmulo de depósitos minerais em tubulações e aparelhos que usam água regularmente, afetando o desempenho e o ciclo de vida desses itens. Além disso, na presença de sabão, os ácidos graxos formam um precipitado insolúvel com íons cálcio, dificultando a espuma e a limpeza, além de outros problemas gerados pelo alto conteúdo dos íons Ca2+ e Mg2+ presentes na água. O objetivo deste trabalho foi estudar a remoção dos íons Ca2+ e Mg2+ usando a SBA-15, um material mesoporoso, funcionalizado com ácido etilenodiaminotetracético e comparado à sua matriz pura. Este adsorvente foi testado em solução de íons Ca2+ e Mg2+ com concentração de 250 mg.L-1 e pH 9, variando a temperatura em 25°C e 50°C. Os materiais mesoporosos foram sintetizados pelo método hidrotérmico e caracterizados por TG-DTG (Termogravimetria e Termogravimetria Derivada), DRX (Difração de Raios X) e BET (método Brunauer, Emmett, Teller). Os resultados da adsorção mostraram uma remoção de até 50% dos íons Ca2+ e Mg2+ em um curto período de tempo, aproximadamente 5 min.

Introduction: Estimating air pollution levels in areas with no measurements is a major concern in health-related studies. Therefore, the aim of this study was to investigate the amount of exposure to particulate matter below 2.5 µ (PM2.5) in the metropolis of Tehran.
Materials and methods: The hourly concentrations of PM2.5  during 2017-2018 period were acquired from the Department of Environment (DOE) and Air Quality Control Company of Tehran (AQCC). The hourly concentrations were validated and 24-h concentrations were calculated. Inverse distance weighting (IDW), Universal Kriging, and Ordinary Kriging were used to spa- tially model the PM2.5  over Tehran metropolis area. Root Mean Square Error (RMSE) and Mean Error (ME) were used to measure and control for the  ac- curacy of the methods.
Results: The results of this study showed that RMSE and MENA values in Kriging method was less than the IDW, which indicates that the Kriging was the best method to estimate PM2.5 concentrations. According to the final map, the highest annual concentrations of PM2.5 were observed in the southern and southwestern areas of Tehran (districts 10, 15, 16, 17, and 18). The lowest exposure to PM2.5 was found to be in districts 1, 2, 3, 6, and 8.
Conclusion: It can be concluded that Kriging method can predict spatial vari- ations of PM2.5 more accurately than IDW method.

Authors: Velayatzadeh Mohammad
Published: September 2020

Human needs clean and healthy air. Clean air is more important than food and water. Industries and industrial activities produce a lot of gases and particles that pollute the air. Air pollution, as one of the concerns of the present age, in addition to environmental degradation and economic damage, poses serious risks to human health. Continuous monitoring of air quality to identify pollut- ants and identify sources of their emissions is also one of the basic strategies for controlling air pollution. Unhealthy air quality causes a lot of damage to humans and the environment and various health effects. Air pollution is a major environmental threat to human health in many developed or develop- ing cities around the world. The level of air pollution is usually determined by the concentration of air pollutants such as dioxide hydrogen, sulfur di- oxide, carbon monoxide, ozone and suspended particles. In recent years, air quality has been a major factor in the emergence of quality of life in urban areas, especially in densely populated and industrial areas. Air pollution with a wide range of suspended particles has effects on human health, including the respiratory and cardiovascular systems, as well as mortality. In this article, the effects of air pollution on the environment and sources and the source of pollution in Ahvaz city are introduced.

Introduction: One of the preventing injuries methods is recognizing common injuries in sports and causative factors of injury. The aims of this study was to investigate the injuries of beach soccer players in terms of prevalence and mechanism.
Methods: The present study is a Cross-sectional and descriptive research that was conducted as a field study. Forty players were selected randomly from two teams of the Yazd province in premier country league that took place in 2019. For recording prevalence and mechanism of injuries, the modified injury report form by Fuller et al. (2006) was used. The SPSS software version 25 and  the chi-square test at a significance level P < 0.05 were used for statistical analysis.
Results: In total, the most common injuries of beach soccer were in lower extremities (%69.84), and for injury severity, %31.75 were severed injury, and in terms of the type of injuries, the strain was the most of the injuries occurred (%33.33). The amount of injury during the match (%60.26) was higher than the time of training (%39.68). The degree of contact injuries %73.02 was significantly higher than non-contact injuries %26.98 (p <0.05).
Conclusion: Most of the injuries in beach soccer are caused by playing bare foot and  lack of shoes and guards on the legs and feet, and then on the knee. Contact of players is one of the main sources of injury in beach soccer, which is likely to be effective in preventing injury by changing training, implementing proper techniques, and improving performance factors by using injuries preventive programs.

Mining Twitter Data to Understand the Human Sentiment on Hurricane Florence
Authors: Yum Seungil
Published: September 2020

Introduction: Most studies have analyzed how natural disasters exert a severe impact on the regional level in the disaster period based on quantitative methods. This study aimed to highlight how Hurricane Florence exerts an impact on human life and societies across US states in a multitude of periods by employing both qualitative and quantitative methods.
Method: This study developed a new app called “Twitgis,” collected 1,433,032 tweets, and employed 57,842 data filtered for Hurricane Florence between 08-21-2018 and 10-01-2018.
Results: First, this study showed that the spatial patterns of tweets are differentiated by periods. For example, the spatial patterns of tweets are more concentrated in the south region in the pre-hurricane period, the spatial patterns of tweets are heavily concentrated in the Southeast region in the hurricane period, and the spatial patterns of tweets are more located in the Northeast region in the post-hurricane period. Second, the most retweeted tweet shows that human sentiment plays an important role in disaster information more than news of the hurricane in online communication. The first ranked tweet is about two times higher than the sum of the retweet numbers between the top two and top 20. Third, this study found that people actively utilize Twitter to share a lot of emotions, opinions, information, and so on for Hurricane Florence. For instance, about one-fifth of tweets in the sentiment analysis are emotions for the hurricane event.
Conclusion: Governments and policymakers should monitor Twitter data to understand the effects of natural disasters on people and the human environment.

Cognitive group rehabilitation Training was applied to the experimental group in 8 sessions with 90 minute. At the end of the course, both groups completed the above questionnaires as a post-test. Data were analyzed by multivariate analysis of covariance with SPSS 24 software.
Result: The results showed that the mean and standard deviation of academic engagement in the pre-test of the experimental group was 52.84 ± 4.41 and the control group was 49.10 ± 4.75 and in the post-test of the experimental group was 83.36 ± 4.35 and the control group 50.75. ± 4.42 was obtained. The mean and standard deviation of academic procrastination in the pre-test of the experimental group of 65.74 ± 8.24and control of 65.32 ± 7.11and in the post-test of the experimental group of 31.02 ± 4.54 and control of 64.11 ± 6.87 Was obtained. Generally the results showed that Cognitive group rehabilitation Training has a significant effect on academic engagement and academic lagging at the level of P < 0.01.
Conclusion: Cognitive group rehabilitation Training should be offered to students to use cognitive strategies and meta-cognitive strategy so that less attention is paid to academic procrastination and lack of academic conflict among students.

Introduction: Peer instructor teaching is an educational model in which senior students teach to their classmates or junior students. Clinical supervision is a formal, systematic, and continuous that the inexperienced person reviews and improves their performance by receiving advice from a supervisor or expert. Clinical education is a vital component of the medical science curriculum and the quality and control of its stressors are important. The purpose of this study was to combine peer instructor training model with clinical supervision on the status and stressors of clinical nursing education.
Methods: This is a quasi-experimental study in which a combined Peer instructor teaching and clinical supervision program was implemented. The research samples were 60 nursing students of Yazd nursing and Midwifery College who were studying in third and sixth semesters. They were selected by purposive sampling method. Data gathering tools included a four-part questionnaire including demographic characteristics, a questionnaire for assessing instructor performance in clinical education, a standard questionnaire for clinical stressors, a course satisfaction questionnaire and a clinical supervisor completed by self-report. Data analysis was done using SPSS 16 software.
Result: on the finding the mean score of peer instructor evaluation was 56.42 ± 9.38 and mean score of clinical stressors was 38.72 ± 5.6. Peer instructor in most cases agreed with the peer instructor program and clinical supervision program.
Conclusion: From the learners' point of view, peer instructor performance is at a good level, as well as clinical stressors at the boundary level between moderate and weak, although both results are satisfactory but there is a need for more careful planning and more training by peer educators and more accurate clinical supervision.

Introduction: Nowadays “change” in all aspects of human's life and organizations is rapidly increasing. By knowing the characteristics of change managers as the main pillars of change in healthcare organizations we can implement effective changes in healthcare systems. Therefore, the aim of this study was to determine the characteristics and competencies of change managers in healthcare system.
Methods: This descriptive cross-sectional study was conducted on nurses in educational hospitals of Kerman University of Medical Sciences in 2016. In this study 280 nurses entered the study based on stratified random sampling. To collect data, a valid and reliable questionnaire was used. Data were analyzed using cluster analysis by SPSS software version 16. 
Result: The highest mean score regarding the characteristics of a change manager was related to "evaluation system and feedback" (9.22 ± 1.17), and "counselor and guider" in the process of change (9.31 ± 1.10). Conversely, "creating an amicable atmosphere in the workplace" (7.35 ± 2.45) and "thinking to reduce resistance" (8.04 ± 1.07) achieved the lowest scores. Totally, 4 roles as futurist and planner; coordinator and information provider; facilitator; and strategist were identified for a change manager in healthcare system.
Conclusion: Characteristics such as futurist, information provider, facilitator and strategist are the main traits of a change manager. Emphasizing these characteristics and making managers ready in this regard can enhance their performance in the process of change and makes the change easier.
A Systematic Review of the Instruments Used for Evaluating Causal Beliefs and Perceived Heart Risk Factors
Authors: Saeidi Mozhgan , Komasi Saeid , Compare Angelo
Published: September 2020

Background: The etiologies and causal beliefs of heart disease are considered one of the 5 dimensions of health selfregulatory model. Thus, the present study aimed to review the literature and screen the appropriate tools for evaluating the causal beliefs and perceived heart risk factors (PHRFs).
Methods: The review samples encompassed all published articles from 1992 to March 2017. A systematic search was conducted across 6 databases: the Web of Science, Scopus, Medline, EBSCO, ProQuest, PsycINFO, and Google Scholar. The qualitative evaluation of the articles was examined using the checklists of the Critical Appraisal Skills Programme (CASP) by 2 independent investigators. After the application of the criteria for inclusion in the study, 22 studies were obtained according to the PRISMA guidelines. 
Results: A total of 10 504 (50.5% male) patients at an average age of 57.85±10.75 years participated in 22 studies under review. The results of the systematic review showed that 22 tools were available to measure PHRFs. The instruments were categorized into 4 groups of valid scales (6 studies), invalid questionnaires (6 studies), checklists (3 studies), and open-ended single items (7 studies). Only 23.2% of the measuring instruments were sufficiently valid.
Conclusion: The results of this systematic review showed that a limited number of valid tools were available to measure PHRFs. Considering the importance of studying cardiac patients’ perception of the etiology of disease and the paucity of standards and valid grading scales, it seems necessary to design and provide tools with broader content that can cover all aspects of patients’ beliefs.

Background: Different arterial segments throughout the vascular system develop similar grades of atherosclerosis concomitantly. Urethral ischemia has been proposed as a cause of urethral stricture. Therefore, we aimed to investigate the relationship between coronary artery disease severity using a SYNTAX score and urethral stricture occurrence after urethral catheterization in patients with non–ST-segment-elevation acute coronary syndrome (ACS).
Methods: This retrospective study consisted of 306 men with urethral catheters that were diagnosed with ACS and underwent coronary angiography between January 2016 and January 2018 in Kars Kafkas University and Osmaniye Government Hospital, Turkey. Hospital records were reviewed to collect the follow-up data of the patients regarding the occurrence of urethral stricture after urethral catheterization. The study population was divided into 2 groups according to urethral stricture development, and both groups were compared statistically.
Results: SYNTAX scores were significantly higher in patients with urethral stricture than in those without urethral stricture (14.86±7.11 vs. 29.25±9.79; P<0.001). The SYNTAX score (OR=1.27; 95% CI: 1.16–1.39; P<0.001), diabetes, and serum albumin were found to be the independent predictors of urethral stricture. The receiver operating characteristic curve analysis showed that the cutoff value of the SYNTAX score for urethral stricture prediction was greater than 22.5, with 76.7% sensitivity and 85.1% specificity (AUC=0.88, 95% CI: 0.84–0.91; P<0.001).

While atherosclerotic plaque disruption remains the hallmark of type 1 myocardial infarction (T1MI), multiple other mechanisms provoking myocardial supply/demand mismatch (eg, anemia and tachyarrhythmias) are recognized as the potential causes of type 2 myocardial infarction (T2MI). In clinical practice, angiography is underutilized in patients with MI that have typical T2MI triggers, although the presence of these triggers and various forms of atherosclerotic coronary artery disease is not mutually exclusive. We describe a 70-year-old man that developed MI during hospitalization for gastrointestinal bleeding. He was treated conservatively without angiography due to posthemorrhagic anemia, which is a recognized T2MI trigger, and subsequently developed refractory cardiogenic shock. Autopsy revealed atherothrombosis, which is characteristic of T1MI.

Focal atrial tachycardias (ATs) arising from the left atrium (LA) most commonly originate from the ostium of the pulmonary vein, the superior mitral annulus, the body of the coronary sinus, the LA septum, and the LA appendage. Focal ATs originating from the posterior wall of the LA are extremely rare. A 34-year-old male patient presented to the cardiology outpatient clinic complaining of palpitation. Electrocardiography showed a tachycardia at a ventricular rate of 150 bpm and a narrow QRS complex. Therefore, an electrophysiological study was performed, which was consistent with an AT. The patient underwent an electrophysiological study in tachycardias with narrow QRS complexes. The diagnostic electrophysiological findings were consistent with an AT. The AT cycle length was found to be 405 ms with variability in the ventriculoatrial interval. Simultaneous LA anatomical and activation mapping was performed during the AT using a 3D electroanatomic mapping system (CARTO) and a quadripolar unidirectional irrigated tip catheter. The activation mapping revealed that the earliest endocardial activation site was at the posterior wall of the LA, where the local electrogram was 72 ms and 35 ms before the coronary sinus reference and the P-wave onset, respectively. The activation mapping also showed centrifugal spreading and mid-diastolic, fractionated signals on the posterior wall. Radiofrequency ablation was successfully performed with 30-watt power at the site of the earliest atrial activation, with a fractionated electrogram terminating the tachycardia. LA posterior ATs are a rare form of AT. The electroanatomic mapping method enables the accurate localization of the LA focal tachycardia, and a high success rate is achieved with ablation therapy.
