Authors: Çotur Özlem Koçtaş , Öztürkoğlu Yücel
Published: October 2019

This chapter considers one of the most important collaborations, namely that of partnership. In recent year's sophisticated and demanding consumer lead severe global competition between companies. So many companies seek to coordinate cross-firm activities and work mutually over time to produce outstanding performance. The main objective of the companies is to reach higher performance than would be achieved by managing individually. For any supply chain in the competitive environment, widening the boundaries of the firm via partnership formation would be the remedy and partnership creates a synergistic business environment for both sides. The objective of the chapter is to present a comprehensive and integrated view of the literature on all aspects of partnership.

Authors: Zhang Genbao , Ran Yan , Luo Dongmei
Published: October 2019

Supply chain quality is the assurance of product quality in its full life-cycle. Although supply chain quality control is a hot topic among researchers, supply chain quality prediction is actually an important but unsolved problem in manufacturing industry. In this paper, an approach of manufacturing supply chain quality prediction based on quality satisfaction degree is proposed to control supply chain better, in order to help ensure product quality. Supply chain quality prediction 3D model and model based on customer satisfaction and process control are established firstly. And then technologies used in quality prediction are studied, including quality prediction index system established on Expert scoring -AHP and prediction workflow built on ABPM. Finally an example is given to illustrate this approach. The customer satisfaction prediction result of supply chain quality can help supply chain management, and the quality prediction software system can make it easier, which provides a new direction for the product quality control technology research.

Authors: Nourani Cyrus
Published: October 2019

This author has for the past decade developed a mathematical basis for product languages, at times with colleagues, applying agent crypto-signatures to authenticate business process models. This chapter is the newest application for what is at recent times called block chain. A new algebraic tree based public key cryptography techniques and algorithm for crypto-signatured block chain processing is presented. The techniques apply agent crypto-signatured algebras and block product language signatures for an agenda-based block chain protocol. An algorithm with a new public key computable trust model for signature tree block parties accomplishes the block chain goals.

Authors: Rajasekaran Rajkumar , Govinda K.  , Masih Jolly , Sruthi M.
Published: October 2019

Most of the elderly citizens are either living by themselves or locked up at home when the rest of the family members go to work. Health of the elderly deteriorates gradually with age, but people fail to notice these changes in everyday life. The elderly are at risk of not receiving attention immediately in the case of emergencies. Internet of things can be used to alert family members and health personnel immediately when an abnormality in the elderly person's health is sensed to prevent discovery of illness at an irrecoverable stage. Internet of things can monitor parameters like heart pulse rate, body temperature, body movement, position, and location, and raise an alert to take immediate preventive actions. Making this system portable is one of the most necessary requirements because it will be worn by the user. That introduces various conditions in itself. For instance, the system should not disturb the patient or be heavy.
Multi-Criteria Evaluation of Reconstruction Strategies for Distribution Power Networks Designed for Rural Power Supply
Authors: Leshchinskaya Tamara , Podobedov Pavel , Maslennikov Pavel , Nekrasov Anton , Nekrasov Alexey
Published: October 2019

The rural distribution network has deteriorated. This is due to the high failure rate of electrical equipment, high maintenance costs, reduced power quality, and the increased duration of power outages in agricultural production. This leads to a short supply of electricity, downtime of processing equipment, loss of production or production of low-grade products, as well as excessive energy losses during transmission. The important issue is the development of advanced methods for assessing the feasibility and effectiveness for component replacement of power transmission equipment with newer and more modern, reducing electrical energy loss in the distribution network. To solve these problems, various strategies have been developed and studied to improve the reliability of 10 kV overhead power lines by using modern insulators, wires, and supports.
Industry 4.0 in the Context of the Triple Bottom Line of Sustainability
Authors: Müller Julian M.
Published: October 2019

Industry 4.0 and sustainability are trending topics in the industry and scientific research. However, there is currently no comparable study, which summarizes the impacts of Industry 4.0 on all three dimensions of the Triple Bottom Line at the same time. This chapter aims to present a comprehensive overview of Industry 4.0 in the context of the Triple Bottom Line of sustainability. For this reason, a systematic literature review is conducted to find out the current state of literature about this topic. The chapter presents a systematic literature review on 64 peer-reviewed journal articles, which have been published between 2014 and 2019. An in-depth analysis of the content as well as an analysis of the empirical methodologies are conducted. To structure the existing knowledge, a framework is developed, and the findings are categorized into ecological and social aspects. On this basis the content is evaluated to discuss key findings and relating interdependencies.
Life Cycle Management and Sharing Economy
Authors: Mugion Roberta Guglielmetti , Arcese Gabriella , Toni Martina , Silvestri Luca
Published: October 2019

The life cycle sustainability assessment based on Life Cycle Thinking is currently considered the most crucial paradigm that includes three kinds of sustainability variables. Life cycle management (LCM) is the most holistic approach in promoting sustainable value creation, embedding the social, economic, and environmental dimensions as a management tool. LCM is mainly applied in the manufacturing and products chain, whereas it is understudied in the service industry. This chapter proposes the development of the LCM general framework and the definition of indicators for the assessment of sustainability in the urban shared mobility. The research framework has been tested in the transportation sector focusing on car sharing context.
The Importance of Consumer Perception of Corporate Social Responsibility to Meet the Need for Sustainable Consumption
Authors: Pegan Giovanna , Schoier Gabriella , de Luca Patrizia
Published: October 2019

Industries have to rethink their value creation processes in a sustainable perspective. In order to satisfy their stakeholders and pursue the well-being of society in the long term, manufacturers must operate under corporate social responsibility (CSR). Embodying the identity of multiple stakeholders, consumers are the key to ensuring the success of sustainability efforts. This chapter analyses the relevance of CSR from the perspective of consumer perception, which has been neglected thus far in literature. The chapter also embraces the idea that CSR and sustainable consumption are two sides of the same coin that need to be integrated in order to create sustainable industrial value. After the theoretical background, this work presents and discusses the results of an empirical research focused on an emblematic industry and brand. The findings support the idea that although a company is trying to seize Industry 4.0. opportunities for sustainability, its efforts can be partly hampered by consumers' lack of perception or their misperception.
DNA barcodes reveal inconsistent species boundaries in Diplolepis rose gall wasps and their Periclistus inquilines (Hymenoptera: Cynipidae)

Published: September 2019

Rose gall wasps, Diplolepis Geoffroy (Hymenoptera: Cynipidae), induce structurally distinct galls on wild roses (Rosa Linnaeus; Rosaceae), which provide gallers with food and shelter. These galls are attacked by a wide variety of micro-hymenopterans, including Periclistus Förster (Hymenoptera: Cynipidae), which act as inquilines. Both Diplolepis and Periclistus are difficult to distinguish based on adult morphology, instead the structural appearance of galls is often used to distinguish species. Using the mitochondrial gene cytochrome c oxidase subunit I, we tested the species boundaries and built phylogenies of both Diplolepis and Periclistus. The molecular results have largely supported the validity of species described in the literature, with notable exceptions in four species groups. Periclistus exhibits a divide between the Palaearctic and Nearctic clades, and ranges from specialists to generalists in terms of host specificity. While it is premature to enact any taxonomic changes without additional molecular markers, this incongruence between morphological and molecular data indicates these groups need taxonomic revision and gall morphology alone may be inadequate to delimit species.
TNF-Mediated Compensatory Immunity to Mycobacterium avium in the Absence of Macrophage Activation by IFN-γ

Published: September 2019

Granuloma formation is a hallmark of several infectious diseases, including those caused by Mycobacterium sp. These structures are composed of accumulations of inflammatory cells, and it has been shown that cytokines such as IFN-γ and TNF-α are required for granuloma assembly during M. avium infections in mice. Macrophages (MΦs) insensitive to IFN-γ (MIIG) mice have MΦs, monocytes, and dendritic cells that are unresponsive to IFN-γ. We observed that although IFN-γ−/− mice present an exacerbated infection, the same is not true for MIIG animals, where the same levels of protection as the wild-type animals were observed in the liver and partial protection in the spleen. Unlike IFN-γ−/− mice, MIIG mice still develop well-defined granulomas, suggesting that IFN-γ–mediated MΦ activation is not required for granuloma assembly. This work also shows that MIIG animals exhibit increased cell recruitment with higher CD4+ T cells numbers as well as increased IFN-γ and TNF-α expression, suggesting that TNF-α may have a role in protection and may compensate the lack of MΦ response to IFN-γ in the MIIG model. TNF-α–deficient MIIG mice (MIIG.TNF-α−/−) exhibited increased bacterial burdens when compared with MIIG mice. These results suggest that in the absence of IFN-γ signaling in MΦs, TNF-α has a protective role against M. avium.

Published: September 2019

Anemia is a frequent and challenging complication of mycobacterial infections. We used a model of disseminated Mycobacterium avium infection in mice to investigate the mechanisms of mycobacteria-induced anemia. We found increased formation of RBC in the bone marrow and spleen of infected mice. Infection induced reticulocytosis and the premature egress of immature progenitors to the systemic circulation in an IFN-γ (IFNG)–dependent way. The newly formed RBC had reduced CD47 surface expression and a reduced life span and were phagocytosed in the liver of infected mice, increasing iron recycling in this organ. The increased engulfment and degradation of RBC was independent of IFNG sensing by macrophages. Together, our findings demonstrate that mycobacterial infection alters the formation of erythrocytes, leading to their accelerated removal from circulation and hemolytic anemia. This comprehensive elucidation of the mechanisms underlying mycobacteria-induced anemia has important implications for its efficient clinical management.
STAT4 Directs a Protective Innate Lymphoid Cell Response to Gastrointestinal Infection
Authors: Dulson Sarah J. , Watkins Emily E. , Crossman David K. , Harrington Laurie E.
Published: September 2019

Innate lymphoid cells (ILCs) are strategically positioned at mucosal barrier surfaces where they respond quickly to infection or injury. Therefore, we hypothesized that ILCs are key contributors to the early immune response in the intestine against Listeria monocytogenes. Using a modified strain of L. monocytogenes that mimics human gastrointestinal listeriosis in mice, we find ILCs to be essential for control of early replication of L. monocytogenes in the intestine as well as for restricted dissemination of bacteria to peripheral tissues. Specifically, group 1 ILCs (ILC1s) and group 3 ILCs (ILC3s) respond to infection with proliferation and IFN-γ and IL-22 production. Mechanistically, we show that the transcription factor STAT4 is required for the proliferative and IFN-γ effector response by ILC1s and ILC3s, and loss of STAT4 signaling in the innate immune compartment results in an inability to control bacterial growth and dissemination. Interestingly, STAT4 acts acutely as a transcription factor to promote IFN-γ production. Together, these data illustrate a critical role for ILCs in the early responses to gastrointestinal infection with L. monocytogenes and identify STAT4 as a central modulator of ILC-mediated protection.

The innate immune sensing of allergens or allergen-associated components regulate the development of type 2 inflammatory responses. However, the underlying molecular basis by which allergens or allergen-associated components are detected by innate immune receptors remains elusive. In this study, we report that the most common aeroallergen, house dust mite (HDM), harbors a dsRNA species (HDM-dsRNA) that can activate TLR3-mediated IFN responses and counteract the development of an uncontrolled type 2 immune response. We demonstrate that the mouse strains defective in the dsRNA-sensing pathways show aggravated type 2 inflammation defined by severe eosinophilia, elevated level of type 2 cytokines, and mucus overproduction in a model of allergic lung inflammation. The inability to sense HDM-dsRNA resulted in significant increases in airway hyperreactivity. We further show that the administration of the purified HDM-dsRNA at a low dose is sufficient to induce an immune response to prevent the onset of a severe type 2 lung inflammation. Collectively, these results unveil a new role for the HDM-dsRNA/TLR3–signaling axis in the modulation of a type 2 lung inflammation in mice.
Is the nasal route a viable option for relieving acute pain in pediatric emergency medicine? A literature review
Authors: Aleysae Nabil Abdulrahman
Published: October 2019

In recent years, the nasal route has increasingly been viewed as an alternative option for the delivery of analgesia, especially when the traditional ways are complicated or time-intensive. However, little is known about the value of this intervention in acute pain management in pediatric emergency medicine. This evidence-based analysis review aims to assess the current evidence regarding the use, safety, and effectiveness of intranasal analgesics in acutely painful conditions encountered in Pediatric Emergency Departments (PEDs). A systemic electronic searching of Cochrane library, PubMed, and EMBASE databases from the beginning of each database until October 2018 was conducted using a maximally sensitive searching strategy. Only randomized controlled trials (RCTs) or quasirandomized controlled trials that evaluated the use of intranasal analgesia for acute pain in children in the Emergency Department and published between January 1990 and October 2018 were included. The methodological quality of the trials was assessed using the Grading of Recommendations Assessment, Development, and Evaluation criteria. Risks of bias within each included study were evaluated according to the Cochrane Risk of Bias Tool for RCTs. This review was reported following the Preferred Reporting Items for Systematic Reviews and Meta- Analyses statement. Seven RCTs and one quasi-randomized study met the inclusion criteria. Five studies compared an intranasal analgesic and an alternative intervention, two compared intranasal fentanyl against ketamine, and one compared two different concentrations of intranasal fentanyl. All included trials reported reductions in pain scores, especially within the first 10 to 30 minutes post-intervention; however, pain reduction was maintained to 60 minutes in only one study. No evidence of significant adverse events was associated with the administration of any intranasal analgesic in any of the included studies. This review identified eight articles that discussed the intranasal analgesia as a possible route of analgesia in the PED. While no paper was entirely perfect, the findings support the idea that intranasal analgesia may be an effective analgesic for the treatment of children (3-18 years) with acute moderate to severe pain, and its administration appears to cause minimal adverse effects.

Published: October 2019

The current research was carried out to study the incidence of Escherichia coli (E. coli) in Egyptian cheese (Kariesh and Ras) and molecular characterization of certain E. coli virulence genes (stx1, stx2, eaeA, hlyA and fimH) using multiplex PCR technique. Biocontrol of E. coli with essential oils (clove and thyme oil) was also studied. A total of 150 random samples of Kariesh and Ras cheese (75 each) were collected from various areas in Governorate of Menoufia. According to our results, the frequency of E. coli isolated from Kariesh and Ras cheese was 16% and 5.3%, respectively. Serological identification classified the E. coli strains into two groups, enterohemorrhagic E. coli (EHEC) serogroup (O26: H11, O91: H21, O111: H2 and O103: H2). While the enterotoxigenic E. coli (ETEC) serogroup were detected as O125: H21 which is the most prevalent strain. O171: H2, O86 and O119: H6 belonging to enteropathogenic E. coli (EPEC). The most prevalent gene detected in E. coli strains was stx1 (87.5%) followed by stx2 (86%), fimH (75%), hlyA (50%) and eaeA (25%) genes. Concerning the antimicrobial activity with essential oils, thyme oil (1%) is considered as the bactericidal effect against E. coli (ATCC35150) with improved the sensory evaluation than clove oil (1%). In conclusion, Kariesh and Ras cheese are extremely tainted with pathogenic E. coli strains, which represent a strong hazard on the human health.

Published: October 2019

In the last years, amateur doping phenomenon has caused many victims. In order to know the diffusion of this phenomenon, we conducted an online survey thanks to Google forms. We also converted on paper the same questionnaire and we administered it in many gyms in Palermo and Trapani (Sicily, Italy). The examined sample consists of 976 people aged between 14 and 65 (47.3% of them are women and 52.7% are men). We asked them if they had ever taken substances to improve their athletic performances: 25.8% of them answered affirmatively and declared to take protein, amino acids, but also Ephedrine, Caffeine, Aspirin on a regular basis (34.6%). They bought these substances in sporting stores (32.2%), in pharmacy without prescription (26.8%), on the Internet (22.8%), in gyms (10.7%); 7.5% of them answered that they bought substances in other places. Furthermore, 17.9% of them declared that training companions, but also coaches and/or responsible of sports societies, proposed them to take doping-substances (Stanazolol, Tamoxifen, Testosterone, Erythropoietin, etc.). 16.8% of interviewed claimed that it is right to take substances with the purpose to improve their performances. However, 95% of respondents said they had never given such substances to their children. They also declared they wanted more information about the true risks related to uncorrected doping-substances intake. In conclusion, it appears necessary to adopt measures of information and prevention to reduce the diffusion of this dangerous phenomenon.
Burnout Levels and Mood States Among Athletic Training Students in Professional Master's Programs
Authors: Bryant Kaleshia , Bradney Debbie A. , Favero Domenica , Bowman Thomas G.
Published: September 2019

Context

Professional master's athletic training students are at high risk for changes in mood state and an increase in burnout levels during an academic semester due to stressors including academic workload, clinical expectations, and/or research projects, among other factors.

Objective

To determine mood states and burnout levels among professional master's students during the middle and end of an academic semester.

Design

Cross-sectional study.

Setting

Online survey.

Patients or Other Participants

The sample consisted of first and second year professional master's students (males = 11, females = 30, age = 23.39 ± 1.44 years) who attended Commission on Accreditation of Athletic Training Education accredited athletic training programs.

Interventions

The independent variable was time (midsemester and end of semester). We sent the link to the online survey via e-mail to program directors and asked them to forward it to all students in the professional master's programs they led.

Main Outcome Measure(s)

The dependent variables were the subsets of burnout (depersonalization [DP], personal accomplishment, and emotional exhaustion [EE]) along with the overall mood state score. We used the modified 22 item Maslach Burnout Inventory and the modified 40 item Profile of Mood States.

Results

Burnout scores from the personal accomplishment subscale of the Maslach Burnout Inventory were statistically different between the 2 time points ({\rm{\chi }}_1^2 = 5.765, P = .016) in comparison to DP ({\rm{\chi }}_1^2 = 0.027, P = .869) and EE ({\rm{\chi }}_1^2 = 1.256, P = .262). For Profile of Mood States scores, the composite total mood disturbance score was not statistically different between the 2 time points ({\rm{\chi }}_1^2 = 0.200, P = .655).

Conclusions

Our findings indicated that, as a whole, high level stressors were reported from lack of personal accomplishment. Clinically, mood states were reported to not change from midsemester to end of the semester.
Exploring the Development of a Mentoring Relationship Among Newly Credentialed Athletic Trainers
Authors: Singe Stephanie Mazerolle , Walker Stacy W.
Published: September 2019

Context

Mentorship has been identified as a primary organizational socialization tactic and has been directly associated with transition to practice.

Objective

Understand how the mentoring relationship develops for the newly credentialed athletic trainer during the first year of clinical practice.

Design

Grounded theory.

Setting

Athletic training practice settings.

Patients or Other Participants

Thirteen athletic trainers, who graduated from a professional master's program, certified between February and July of 2016, and obtained employment between July to August of 2016, participated in this study (6 female, 7 male, 26 ± 3 years; work settings included professional sports, college, secondary and middle school, and clinic). Data saturation was met.

Main Outcome Measure(s)

Semistructured phone interviews were conducted with all participants during 3 specific time points (3, 8, and 12 months posthire). All interviews were transcribed verbatim and coded following the steps of a grounded theory study. Credibility strategies included researcher triangulation and peer review.

Results

All 13 participants recognized a mentor, someone who they believed serve in a mentoring capacity during their transition into clinical practice as a newly credentialed athletic trainer. The development of the mentoring relationship for the newly credentialed athletic trainer appeared to be characterized by (1) identification of a mentor who had experience and knowledge, (2) a recognition of the need to have support and continued avenues for growth as a health care professional, (3) an informal initiation of the relationship through a professional relationship by the mentee, and (4) communication that overtime was reduced in frequency.

Conclusions

Mentors provide career support and professional growth. Newly credentialed athletic trainers should seek out mentors who can support their continued development. The informal relationship appears to be of the greatest importance during the first few months of practice, and then once comfort and self-confidence improves, the frequency of communication is reduced.

Published: September 2019

Orientation: Coaching has the potential to align the expectations between young millennial professionals and their organisations as coaching in a business context should result in mutually beneficial outcomes valued by both the coachee and the organisation.Research purpose: The research reported in this article explored how coaching contributes to the alignment of the psychological contract between an organisation and the young millennial professional.Motivation for the study: The work-related preferences and expectations of millennials can result in misalignment in the psychological contract between organisations and young millennial professionals, negatively affecting their level of engagement; performance and tenure. There is a paucity of research into building psychological contract mutuality and the coaching of millennials.Research approach/design and method: A phenomenological approach within a qualitative research design was followed. This included semi-structured interviews with seven young millennial professionals who had been coached and email interviews with five coaches who had coached young millennial professionals.Main findings: Coaching can enhance the psychological contract between young millennial professionals and their organisations, particularly with regard to career development. Alignment in expectations regarding career development may result in improved performance; enhanced affective commitment and lower turnover.Practical/managerial implications: Coaching is a viable strategy for organisations to engage and retain their young millennial professionals by cultivating psychological contract alignment in the employer-employee relationship.Contribution/value-add: This research supplements the limited body of knowledge on building psychological contract mutuality and coaching efficacy for young millennials.
Renoprotective effect of irbesartan in a rat model of gentamicin-induced nephrotoxicity: Role of oxidative stress
Authors: Al-Kuraishy Hayder M. , Al-Gareeb Ali I. , Al-Naimi Marwa S.
Published: October 2019

BACKGROUND: The renin–angiotensin system (RAS) is essential in renal physiology; however, disturbance of the RAS is one of the chief pathways involved in renal injury. Dysregulation of RAS may result in both glomerular and tubulointerstitial injuries through direct effects of angiotensin II (Ang II) type 1 receptor. Irbesartan and other Ang II blockers have renoprotective effect through reduction of on renal inflammations. Therefore, the aim of the present study was to demonstrate the renoprotective effect of irbesartan on gentamicin-induced nephrotoxicity in rats concerning the oxidative stress.

MATERIALS AND METHODS: Thirty Sprague-Dawley Male rats divided into three groups, Group I (10 rats) treated with distilled water, Group II (10 rats) treated with gentamicin, and Group III (10 rats) treated with gentamicin plus irbesartan for 12 days. Blood urea, serum creatinine, serum malondialdehyde (MDA), superoxide dismutase (SOD), glutathione reductase (GSH), neutrophil gelatinase-associated lipocalin (NGAL), kidney injury molecules (KIM-1), and cystatin-c were measured in each group.

RESULTS: Irbesartan significantly reduced blood urea, serum creatinine, serum MDA, NGAL, KIM-1, and cystatin-c P < 0.05. Irbesartan significantly increases SOD P < 0.05 without significant effect in elevation of GSH serum levels.

CONCLUSION: Irbesartan has renoprotective effect in attenuation of acute nephrotoxicity through modulation of oxidative stress and antioxidant capacity in rats.
Ping-pong configurations and circular orders on free groups

We discuss actions of free groups on the circle with “ping-pong” dynamics; these are dynamics determined by a finite amount of combinatorial data, analogous to Schottky domains orMarkov partitions. Using this, we show that the free group

F_n

admits an isolated circular order if and only if

n

is even, in stark contrast with the case for linear orders. This answers a question from [21]. Inspired by work in [2], we also exhibit examples of “exotic” isolated points in the space of all circular orders on

F_2

. Analogous results are obtained for linear orders on the groups

Willis theory via graphs
Authors: Bywaters Timothy P. , Tornier Stephan
Published: September 2019

We study the scale and tidy subgroups of an endomorphism of a totally disconnected locally compact group using a geometric framework. This leads to new interpretations of tidy subgroups and the scale function. Foremost, we obtain a geometric tidying procedure which applies to endomorphisms as well as a geometric proof of the fact that tidiness is equivalent to being minimizing for a given endomorphism. Our framework also yields an endomorphism version of the Baumgartner–Willis tree representation theorem. We conclude with a construction of new endomorphisms of totally disconnected locally compact groups from old via HNN-extensions.

Published: September 2019

В рамках динамической теории спиновых флуктуаций учтено электрон-фононное взаимодействие. Получено выражение для собственно-энергетической части, явно зависящее от спиновых флуктуаций и колебаний решетки. Результаты теории проиллюстрированы на примере железа. Показано, что влияние фононов на температурную зависимость магнитных характеристик металлов заметное, но не настолько большое, как в статическом одноузельном приближении теории спиновых флуктуаций и спиновой динамике с классическими гамильтонианами.
Приближенная формула для полного сечения рассеяния в случае умеренно малой эйкональной функции
Authors: Kisselev Alexander Victorovich
Published: September 2019

Изучено эйкональное приближение для полного сечения рассеяния неполяризованных частиц. В случае, когда эйкональная функция $\chi(b)$ является умеренно малой, $|\chi(b)|\lesssim 0.1$, получена приближенная формула. Показано, что полное сечение дается рядом из несобственных интегралов, содержащих борновскую амплитуду $A_{\mathrm B}$. Преимущество этого представления по сравнению со стандартными эйкональными формулами состоит в том, что указанные интегралы не содержат быстро осциллирующих функций Бесселя. Доказаны две теоремы, которые позволяют связать асимптотическое поведение функции $\chi(b)$ при больших $b$ с аналитическими свойствами борновской амплитуды. Приведено несколько примеров применения данных теорем. Для проверки эффективности основной формулы она используется в численных расчетах полного сечения с выбором конкретных выражений для $A_{\mathrm B}$. В качестве борновских амплитуд выбираются только те выражения, которые приводят к умеренно малым эйкональным функциям и дают правильную асимптотику функции $\chi(b)$. Эти расчеты показывают, что полученная формула, если учитывать в ней лишь три первых ненулевых члена, аппроксимирует полное сечение рассеяния с относительной точностью $\mathcal O(10^{-5})$.

В момент отрыва нуклона от фермионного ядра оно превращается в бозон. Исследуются дальнейшие превращения бозонного и фермионного состояний отрыва в малой окрестности нулевого давления.
Получены новые важные соотношения парастатистики, связывающие температуру и химический потенциал при отрыве нуклона от атомного ядра. Полученные соотношения позволяют построить новую диаграмму ($aF$-диаграмму) для изотерм очень высоких температур, отвечающих ядерной материи.
Математически доказано, что переход частиц из области, подчиняющейся статистике Ферми-Дирака, в область, подчиняющуюся статистике Бозе-Эйнштейна в окрестности нулевого давления $P$, происходит в нейтронной области неопределенности, или в области гало. Получены уравнения для химического потенциала, позволяющие определить ширину области неопределенности.
На основе вычисленных значений минимальной интенсивности для бозе-частиц, химического потенциала, фактора сжимаемости и минимальной среднеквадратичной флуктуации химического потенциала построена таблица стабильных ядер химических элементов, демонстрирующая монотонную связь между массовым числом ядра и остальными параметрами.
Ecofeminismos en la práctica artística. El cuerpo como símbolo y territorio de acción
Authors: Soto Sánchez Pilar
Published: October 2019

El presente artículo expone el ecofeminismo como una corriente necesaria para la transformación  hacia sociedades sostenibles, un modelo activo que unido a las prácticas artísticas se convierte en una herramienta capaz de visibilizar las raíces de la crisis socioambiental y proporcionar claves imprescindibles para la toma de conciencia. De forma breve se muestra cómo algunas propuestas artísticas basadas en los principios del ecofeminismo utilizan el cuerpo como símbolo, como territorio a explorar y como material común con el que visibilizar y denunciar la estructura defectuosa sobre la que se ha construido una sociedad patriarcal, capitalista y antropocéntrica. Ellas utilizan el cuerpo como instrumento con el que redefinir los discursos de poder y reivindicar su identidad, autonomía y libertad. Desde su práctica artística pretenden revertir sobre el imaginario y la conciencia y a su vez proponen alternativas de acción para la transformación. Las artistas que se presentan en este artículo trabajan desde el pensamiento crítico, poético y político para atacar directamente al imaginario colectivo. Desde el arte nos hacen reflexionar sobre el pasado, el presente y el futuro de la relación entre la humanidad y la naturaleza en términos de respeto, feminismo y ecología.
La identidad falsa como estrategia de (in)visibilidad de las mujeres pioneras de la performance (México/España, 1926-36)
Authors: Mindek Dubravka , Molina-Alarcón Miguel
Published: October 2019

En este trabajo se analiza el doble carácter paradójico de visibilidad e invisibilidad, así como de lo verdadero y lo falso, de que tuvieron que servirse toda una serie de mujeres de inicios del siglo XX en el ámbito español y mexicano, para mostrar las identidades ajenas a la vez que ocultar las propias – las de género y otras- y desvelar una realidad social contradictoria. Como objeto de estudio, miraremos sus acciones como posibles expresiones precursoras de la performance, una práctica artística que vendría muchos años después y que aquí encontramos sus indicios (aunque ellas no lo pretendieran) por el uso creativo que hicieron desde sus propios cuerpos. Estas mujeres realizaron una especie de observación participante encubierta, en términos antropológicos, en diferentes ámbitos de sus respectivas sociedades, lo que les permitió pasar desapercibidas, pero a la vez hacer visibles diferentes problemáticas e identidades sociales y de género. Las mujeres cuyos casos se analizarán son la mexicana Concepción Jurado que se hizo pasar por un millonario español entre 1926-1931; y las periodistas españolas Magda Donato, Josefina Carabias y Luisa Carnés, que entre 1932-1936 se infiltraron con identidades falsas en instituciones de salud mental, cárceles, hoteles, peluquerías e inclusive adoptaron el rol de una mujer buscando trabajo, para visibilizar su lado invisible, denunciar sus condiciones sociales y laborales y señalar las construcciones y las inequidades de género en torno a ellos. Todo un arte de acción ¿por qué no?

Violencia escolar: diferencias de género en estudiantes de secundaria
Authors: Dominguez-Alonso José , López-Castedo Antonio , Nieto-Campos Begoña
Published: October 2019

El género constituye un aspecto esencial de la violencia escolar en estudiantes de educación secundaria obligatoria (ESO). El objetivo de este estudio fue analizar, mediante un diseño transversal, las diferencias de género en las percepciones de la violencia escolar medidas a través del cuestionario de violencia escolar percibida (CUVE-R-ESO). El cuestionario fue administrado a 4467 alumnos (50.3% mujeres) de 1º a 4º de ESO con un rango de edad entre 12 y 16 años (M = 13.81; DT = 1.38). Los resultados evidencian una ligera prevalencia del género femenino sobre el masculino en las acciones que conforman los diferentes tipos de violencia escolar. Asimismo revelaron diferencias significativas entre ambos, atribuyendo que los chicos están más relacionados con la violencia ejercida por parte del profesorado hacia el alumnado, violencia física indirecta, violencia física directa o la exclusión social, y las chicas con la violencia verbal, violencia del alumnado hacia el profesorado y la disrupción en el aula. Finalmente, es significativa pero escasa la aportación del género como variable predictora en la violencia escolar. En conclusión, se evidencia la necesidad de diseñar programas de prevención o intervención que tengan en cuenta la variable género.
La Lesson Study. Una metodología para reconstruir el conocimiento docente universitario
Authors: Hevia Artime Isabel , Fueyo Gutierrez Aquilina , Belver Dominguez José Luis
Published: October 2019

El artículo describe los resultados de un estudio de caso para la mejora de la práctica docente universitaria a partir de la reflexión y la creación de una comunidad de práctica profesional en el Grado de Pedagogía de la Universidad de XXX. Para ello, la metodología de Lesson Study se convierte en el eje del estudio de caso sobre las estrategias más adecuadas para trabajar con un grupo de 98 estudiantes en el análisis y producción de mensajes audiovisuales con enfoque de género. Las técnicas cualitativas de recogida de información empleadas son la observación, los diarios de campo, entrevistas y un grupo de discusión final. El proceso de investigación evidencia la eficacia de esta metodología a la hora de comprender y reconstruir el conocimiento práctico del profesorado universitario sobre el proceso de enseñanza y aprendizaje, a la vez que descubre nuevos interrogantes y áreas de mejora docentes no identificadas inicialmente.
The use of nondialogic trolling to disrupt online communication
Authors: Britt Brian C.
Published: October 2019

Trolling, a uniquely common antisocial behavior in online communities, has traditionally been conceptualized as a phenomenon based in group dialogue. Yet it is possible for trolling to occur without any actual dialogue between the troll and the intended targets. In this paper, several methods of trolling are presented, each of which is performed through engagement with user-generated media artifacts rather than through back-and-forth conversation among users. These are broadly grouped into four categories based on the type of media engagement that is exploited: content creation, content curation, content evaluation, and content refinement. This manuscript therefore fills a significant gap in the literature on this topic and helps to resolve a limitation in existing explications of the construct by showing its applicability to a wider range of behaviors than previously acknowledged.
“He wondered why a road should come to such a place”: Community and Posthumanism in Cormac McCarthy's Outer Dark
Authors: Elmore Jonathan , Elmore Rick
Published: September 2019

There is wide scholarly agreement that Outer Dark is, by and large, a tale whose nihilism and ambiguities offer little philosophical or anthropological insight beyond a masterful rumination on the darkly paradoxical nature of human existence. While such interpretations are compelling, a careful reading of the novel's central theme of incest shows that Outer Dark offers an alternative, productive account of human nature and community. More specifically, McCarthy's text explores the ways in which community formation requires an always violent logic of inclusion and exclusion, this logic creating the very bodies and communities it claims merely to classify. This power to create bodies and communities shows that, for McCarthy, the possibility for human difference, for humans to be something new, remains always in play. Hence, our article concludes that in the figure of Rinthy, McCarthy gives us an alternative conception of human life, a proto-posthumanism that might offer a way through the totalizing and dehumanizing structures of modern society.

Byzantine archaeological sites tend to be seen as representative of the empire as a whole, with little concern given to regional context. Within the imperial narrative that shapes Byzantine history, sites—whether urban or rural—are often used to explain and illustrate imperial trends. However, when we remove that overarching narrative, the sites in Anatolia provide the potential to view them as singular examples of local and regional identity. In this article, we have separated out four types of data: fortifications, coins, faunal material, and archaeobotanical evidence to illustrate how a close examination of the data provides new ways of understanding regional identity. In doing so, we posit that the Byzantine empire needs to be seen as a collection of local identities working alongside one another, but always expressing individual needs and resources.
DESCOLONIZAÇÃO METAFÍSICA: ESBOÇO DE MANIFESTO CONTRA-FILOSÓFICO
Authors: Valentim Marco Antonio
Published: September 2019

Este breve ensaio toma como ponto de partida a hipótese de que há um vínculo constitutivo do discurso ﬁlosóﬁco moderno com o etnocídio, exempliﬁcado pelo cosmopolitismo kantiano enquanto paradigma do “racismo europeu” (Deleuze & Guattari). Buscam-se os fundamentos metafísicos desse vínculo com apoio no diagnóstico do processo colonial produzido por Lévi-Strauss e, sobretudo, por Fanon e Césaire. Sustenta-se que, de um ponto de vista metafísico, colonização e descolonização se caracterizam por modos divergentes de realizar a diferença ontológica de mundo entre povos distintos. O ensaio esboça, por ﬁm, uma problematização do papel histórico da ﬁlosoﬁa na instituição da colonialidade.
A VERGONHA QUE NÃO NOS PERTENCE
Authors: Jugend Gustavo
Published: September 2019

Buscamos no presente trabalho redeterminar a categoria ﬁlosóﬁca de sujeito, levando em conta o evento de Auschwitz. Será apresentada, a partir da leitura de textos de Giorgio Agamben e de testemunhas dos campos de concentração nazistas, uma análise dos movimentos de subjetivação e dessubjetivação que constituem o indivíduo. Tal deﬁnição não pode vir desacompanhada de um estudo da linguagem e, por isso, este texto sempre manterá a possibilidade da fala em seu horizonte teórico. Está em pauta também a compreensão ou, pelo menos, a especulação de um novo discurso acerca da ética, uma vez que uma nova compreensão acerca do sujeito assim o demandaria.
