Model Quality Assessment Method Based on Support Vector Machine
Authors: Glodek Łukasz , Bysko Szymon , Nocoń Witold
Published: July 2021

This paper proposes a model quality assessment method based on Support Vector Machine, which can be used to develop a digital twin. This work is strongly connected with Industry 4.0, in which the main idea is to integrate machines, devices, systems, and IT. One of the goals of Industry 4.0 is to introduce flexible assortment changes. Virtual commissioning can be used to create a simulation model of a plant or conduct training for maintenance engineers. On a branch of virtual commissioning is a digital twin. The digital twin is a virtual representation of a plant or a device. Thanks to the digital twin, different scenarios can be analyzed to make the testing process less complicated and less time-consuming. The goal of this work is to propose a coefficient that will take into account expert knowledge and methods used for model quality assessment (such as Normalized Root Mean Square Error – NRMSE, Maximum Error – ME). NRMSE and ME methods are commonly used for this purpose, but they have not been used simultaneously so far. Each of them takes into consideration another aspect of a model. The coefficient allows deciding whether the model can be used for digital twin appliances. Such an attitude introduces the ability to test models automatically or in a semi-automatic way.

Implementation of the Digital COVID-19 Vaccination Passport based on Blockchain Protecting Privacy
Authors: Pukocz Przemysław
Published: July 2021

The paper discusses proposals for implementing the COVID-19 digital Vaccination Passport based on Blockchain that protects privacy. Since the end of the last year, after the commencement of vaccination against COVID-19, there has been an intense discussion on the form of introducing such a tool and the consequences of its implementation. This discussion is taking place in many European countries. One element of this discussion was the safety and anonymity of the massively verified data of persons on vaccinations in various areas of society functioning. These issues are being resolved by the proposed digital Vaccination Passport system. This system uses two major methods: Blockchain and hash functions, which allow you to maintain security, privacy, and anonymity at the same time. To improve the intuitiveness and simplicity of the system operation, the QR code technology was proposed in the passport verification process. The system has been implemented and tested in the Amazon AWS cloud computing environment. A reference architecture based on Blockchain for the AWS environment was proposed, dedicated to large and demanding application solutions. In addition, the cloud environment offers access to many tools that were used in the system’s implementation, significantly increasing the security of the entire solution.
The role of glycation end products in the development and progression of diabetic neuroarthropathy
Authors: Kalandiya M. M. , Tokmakova A. Yu. , Galstyan G. R.
Published: July 2021

Diabetic neuroarthropathy (DNOAP, Charcot’s foot) is a serious complication of diabetes mellitus, the genesis of which is not fully understood. In most cases, this pathology is diagnosed late, which leads to the development of severe deformities of the foot, up to the loss of support ability of the limb. There is no single hypothesis for the formation of Charcot’s foot, but there are factors predisposing to its development, as well as a few likely provoking events. Excessive formation and accumulation of end products of glycation may play an important role in the pathogenesis of this complication of diabetes. End products of glycation (AGE) are a variety of compounds formed as a result of a non-enzymatic reaction between carbohydrates and free amino groups of proteins, lipids and nucleic acids. There are various factors that lead to the accumulation of AGE in the human body. Allocate endogenous and exogenous factors. The former include certain diseases, such as diabetes mellitus, renal failure, which accelerate glycation processes. Exogenous factors leading to the formation of lipo-oxidation and glyco-oxidation products include tobacco smoke and prolonged heat treatment of food.

This review provides information on the role of glycation end products in the development and progression of complications in patients with diabetes mellitus.

Published: July 2021

Parahancornia amapa is an Amazonian tree that produces an edible white exudate widely used in folk medicine and food. Studies have found the presence of carbohydrates and bioactive compounds in its composition. The riverside population of the Amazon reports the use of this exudate against respiratory diseases and inflammation. This brief communication aimed to show the bioactive potential of the amapá bitter latex. Samples obtained from four different cities were studied and microbiological, physicochemical, mineral, and bioactive compounds were analyzed (Total Phenolic and antioxidant activity by ORAC and FRAP methods). The results showed relevant physicochemical and mineral composition (Ca, Mg and Zn values suggested by the RDA). Furthermore, we found good antioxidant activity throughout latex. The sample from the city of Cametá-PA showed higher values for Total phenolics, and antioxidant activity ORAC and FRAP, respectively. This study is important due to the interesting composition of Parahancornia amapa, which has the potential to be applied in technological routes in the food area.
Percepções e conhecimentos dos estudantes sobre fungos
Authors: Silva Aline da Costa , Gouw Ana Maria Santos
Published: July 2021

O presente estudo trata-se de uma pesquisa sobre as percepções e conhecimentos que os estudantes concluintes do ensino médio apresentam sobre fungos, organismos de importância ecológica, médica e econômica. O percurso metodológico desta investigação envolveu a participação de 305 estudantes da rede pública e privada do município de Diadema/SP, cidade localizada na Região Metropolitana do Estado de São Paulo. A coleta de dados ocorreu por meio de um questionário de pesquisa, construído e validado para compreender a visão dos estudantes sobre o assunto. Os resultados evidenciaram que os estudantes finalizam a educação básica com conhecimentos limitados sobre os fungos, de forma a pouco perceber a importância desses organismos no meio ambiente e na vida cotidiana, além de exibir concepções equivocadas sobre esses organismos. Espera-se que os resultados deste estudo ampliem o debate e auxilie em reflexões sobre o ensino de micologia nas escolas e nas instituições de formação de professores, de modo a impactar positivamente no fazer pedagógico dos professores e, consequentemente, no aprender dos estudantes, em especial, quando o assunto em questão forem os fungos.
Statistical modeling of the novel COVID-19 epidemic in Iraq
Authors: Ghanim Al-Ani Ban
Published: July 2021

Objectives

This study aimed to apply three of the most important nonlinear growth models (Gompertz, Richards, and Weibull) to study the daily cumulative number of COVID-19 cases in Iraq during the period from 13th of March, 2020 to 22nd of July, 2020.

Methods

Using the nonlinear least squares method, the three growth models were estimated in addition to calculating some related measures in this study using the “nonlinear regression” tool available in Minitab-17, and the initial values of the parameters were deduced from the transformation to the simple linear regression equation. Comparison of these models was made using some statistics (F-test, AIC, BIC, AICc and WIC).

Results

The results indicate that the Weibull model is the best adequate model for studying the cumulative daily number of COVID-19 cases in Iraq according to some criteria such as having the highest F and lowest values for RMSE, bias, MAE, AIC, BIC, AICc and WIC with no any violations of the assumptions for the model’s residuals (independent, normal distribution and homogeneity variance). The overall model test and tests of the estimated parameters showed that the Weibull model was statistically significant for describing the study data.

Conclusions

From the Weibull model predictions, the number of cumulative confirmed cases of novel coronavirus in Iraq will increase by a range of 101,396 (95% PI: 99,989 to 102,923) to 114,907 (95% PI: 112,251 to 117,566) in the next 24 days (23rd of July to 15th of August 15, 2020). From the inflection points in the Weibull curve, the peak date when the growth rate will be maximum, is 7th of July, 2020, and at this time the daily cumulative cases become 67,338. Using the nonlinear least squares method, the models were estimated and some related measures were calculated in this study using the “nonlinear regression” tool available in Minitab-17, and the initial values of the parameters were obtained from the transformation to the simple linear regression model.
Origin of the low-medium temperature hot springs around Nanjing, China
Authors: Ma Jun , Zhou Zhifang
Published: July 2021

The exploration of the origin of hot spring is the basis of its development and utilization. There are many low-medium temperature hot springs in Nanjing and its surrounding karst landform areas, such as the Tangshan, Tangquan, Lunshan, and Xiangquan hot springs. This article discusses the origin characters of the Lunshan hot spring with geological condition analysis, hydrogeochemical data, and isotope data. The results show that the hot water is SO4–Ca type in Lunshan area, and the cation content of SO4 is high, which are related to the deep hydrogeological conditions of the circulation in the limestone. Carbonate and anhydrite dissolutions occur in the groundwater circulation process, and they also dominate the water–rock interaction processes in the geothermal reservoir of Lunshan. The hot water rising channels are deeply affected by the NW and SN faults. Schematic diagrams of the conceptual model of the geothermal water circulation in Lunshan are plotted. The origin of Tangshan, Tangquan, and Xiangquan hot springs are similar to the Lunshan hot spring. In general, the geothermal water in karst landforms around Nanjing mainly runs through the carbonate rock area and is exposed near the core of the anticlinal structure of karst strata, forming SO4–Ca/SO4–Ca–Mg type hot spring with the water temperature less than 60°C. The characters of the hot springs around Nanjing are similar, which are helpful for the further research, development, and management of the geothermal water resources in this region.

Ben-Zaken, S, Meckel, Y, Nemet, D, and Eliakim, A. Insulin-like growth factor axis genetic score and sports excellence. J Strength Cond Res 35(9): 2421–2426, 2021—It has been suggested that IGF1 polymorphisms associated with circulating IGF1 levels may be linked to elite short-distance running performance. This study assessed genetic score based on 6 polymorphisms related to the Insulin-like growth factor axis (rs7136446, rs35767, rs6220, rs680, rs2854744, and rs1805086) among elite Israeli runners and swimmers. One hundred sixty-one track and field athletes (123 men and 38 women, age 17–50 years) and 94 swimmers (61 men and 33 women, age 16–49 years) participated in the study. Athletes were divided into short-distance runners (SDRs, major event: 100–200-m sprints and jumps, n = 63) and long-distance runners (LDRs, major event: 5,000 m and marathon, n = 98). Swimmers were divided into short-distance swimmers (SDSs, major event: 50–100 m, n = 44) and long-distance swimmers (LDSs, major event: 400–1,500 m, n = 50). Groups were subdivided into top-level and national-level athletes. We calculated the IGF genetic score (IGF-GS) of all the subjects on a 0–100 scale. Top-level SDRs' mean IGF-GS (30.8 ± 11.7) was significantly higher (p < 0.006) compared with national-level SDRs' (20.5 ± 11.3) and top-level SDSs' (19.9 ± 8.5). Subjects with IGF-GS >25 had an increased odds ratio (OR) of being elite-level SDRs (OR: 4.2; 95% confidence interval: 0.68–26.09; p < 0.001). In summary, a combined assessment of 6 single-nucleotide polymorphisms, all known to modulate circulation IGF1 levels, was associated with a higher genetic score among SDRs, emphasizing the importance of the IGF system to land speed sports events but not to swimming events. Whether the IGF-GS may be used for selection of elite-level sprinters in early stages of their athletic career needs to be further investigated.

More Than Victims or Villains
Authors: Méndez Alina R.
Published: July 2021

This essay examines newspaper articles published in California’s Imperial Valley during the mid-twentieth century that reported stories of braceros (guest workers) and undocumented workers suffering accidents, engaging in intra-ethnic violence, falling prey to criminals, and drinking excessively. These news articles, which often cast Mexican migrants as (potentially) criminal, racialized braceros and their undocumented counterparts as outsiders and undeserving. Collectively, these news articles demonstrate that Mexican migrants experienced what Nancy Scheper-Hughes and Philippe Bourgois describe as a violence “continuum” that connects structural, everyday, and symbolic violence in overlapping and intersecting ways. The alcohol abuse and interpersonal violence so common among braceros and undocumented migrants cannot be separated from the structural and symbolic violence that these men confronted in the Imperial Valley. Migrant workers’ structural vulnerability—which placed them in harm’s way while they worked, during times of leisure, or along the migration route—was the cause, but also a byproduct, of the antisocial behavior that some men adopted to cope with their exploitation. Though scholars have long considered the conditions that I here categorize under structural, everyday, and symbolic violence, I argue that by employing the concept of a continuum of violence we can better account for the wide range of experiences that braceros and undocumented migrants encountered in the United States in the mid-twentieth century.
The Temporality of Identity in Planned Cities: A Case Study of Zhong Xing New Village, Taiwan
Authors: Lu Michelle
Published: July 2021

In 1957, the Kuomintang (KMT), Chiang Kai-Shek’s nationalist government, planned and built Zhong Xing New Village (ZXNV), a garden city, to house the Taiwan Provincial Government. Despite the benefits of public housing, healthcare, and education, ZXNV experienced a two-third drop in population after 1985. The political liberalization and democratization of Taiwan in the 1980s and 1990s led to the reclamation of Taiwanese national identity that rejected the hegemony of the KMT and the physical manifestations of this colonial history, including ZXNV. ZXNV was a utopian ideal constructed during a time of authoritarian rule for a specific political purpose and homogenous population. ZXNV’s inability to change its purpose and identity led to its ultimate depopulation. Ethnographic fieldwork reveals the changes in ZXNV’s built environment and neighborhood culture influenced by socio-political transformations over the last sixty years. Fourteen interviews were conducted with two generations of ZXNV residents, and archival research reveals the intended design and policies of the city. Key findings include the structural flaws in the city’s design, the exposure of political tensions between the national and provincial governments, and the changing national identity of Taiwan due to globalization, all of which led to the ultimate downfall of Zhong Xing New Village.
The Gendered Construction of Border-Crossing in Canada: Immigrant and Indigenous Women’s Life Histories in the Tracks of Gloria Anzaldúa
Authors: Hazineh Alia , Jbeili Theresa , Thomas-McNeill Kathleen
Published: July 2021

Our paper offers a new direction for Canadian scholarship on women and border studies by contextualizing women border- crossers within Anzaldúa’s conocimiento model. Based on the narratives of six women border-crossers in Canada, we argue that citizenship is a form of regulatory state-power where “belonging” is bureaucratically defined. For these women, belonging to a homeland is embodied in the interplay between Anzaldúa’s facultad and shadowbeast—between the agency of spirituality and the vagaries of political subjectivity. They crossed the border into Canada, and as a result, the whole of Canada became a borderzone within which they negotiated nepantla (the experience of being “in-between” culture and identity categories). We demonstrate how applying Anzaldúa’s framework to the Canadian context yields new insights into secularism, citizenships, multiculturalism, and belonging.
The Social Functions of College Drinking: Pregaming, Priming, and Protecting the Liminoid Experience
Authors: Schreiber Celine
Published: July 2021

The Harvard School of Public Health College Alcohol Study has concluded that, on average, one in three college students abuses alcohol regularly. However, while highlighting potential risks, academic literature largely neglects the social functions students derive from consuming alcohol. College represents an important milestone in an individual’s life and is characterized by what Turner (1969) called liminoid experiences, which involve a temporary suspension of social status, at bars, clubs, concerts, festivals, and college parties, often closely connected to alcohol consumption. This paper explores how women students’ practice of “pregaming,” that is, drinking alcohol in smaller groups before attending a social event such as a party, enables individuals to achieve the liminoid state while also providing opportunities to resist potential negative consequences of intoxication. College women use pregaming to build a support network with close friends, enabling them to ensure their physical safety. Beyond the integrity of their bodies, women also ensure that their actions during the liminoid experience of a college party are consistent with ideas they have of their personal identity. Although they temporarily suspend their social and personal identities during college parties, women prevent unwanted permanent changes of their sense of self by holding each other accountable to rules they establish during the pregame.
INTERNATIONAL PERFORMANCE ASSESSMENT OF CRITICAL THINKING: FRAMEWORK FOR TRANSLATION AND ADAPTATION
Authors: Ronderos Natalia , Shavelson Richard J. , Holtsch Doreen , Zlatkin-Troitschanskaia Olga , Solano-Flores Guillermo
Published: July 2021

Higher education institutions worldwide claim they impact students’ learning outcomes within and across academic domains. Critical thinking (CT) is prominent among the intended outcomes (Braun et al., 2020). In this context, there is increasing interest in ecologically valid performance assessments (PAs) of CT that can be used internationally (Zlatkin-Troitschanskaia et al., 2018). While several studies have aimed to measure and compare CT skills across countries, this typically has been done using multiple-choice questions. Only a few studies involve adaptation of PAs. Their results point to the need for a more refined adaptation process (Braun et al., 2020), especially in terms of functionally equivalent adaptation and redesign. Based on a review of previous approaches related to test adaptation, with focus on the challenges of achieving cultural responsiveness, we propose a conceptual framework for adapting PAs of CT for international studies. The framework differentiates between two stages and three adaptation designs. The first stage involves a collaborative approach to the design of PAs of CT. The second stage offers three design alternatives which differ in their emphasis on linguistic considerations and cultural responsiveness. While this paper focuses on PAs of CT for higher education, it may be applicable to pre-college education.
PROMOTING LIBERAL EDUCATION THROUGH THE LONGITUDINAL STUDY OF CRITICAL THINKING: A RATIONALE AND PLAN
Authors: Braun Henry , Borowiec Katrina
Published: July 2021

In recent years, U.S. higher education has received much criticism for inadequately preparing students for the ‘real world.’ There is substantial empirical evidence (e.g., Arum & Roksa, 2011) that many students graduate with limited proficiency in key 21st century skills such as critical thinking (CT). Despite its importance in achieving personal advancement and professional success, there has been surprisingly little rigorous research on the development of CT during the undergraduate years. We believe this is a missed opportunity for higher education to better understand the various trajectories of CT development and to generate credible evidence to inform policies, programs, and practices – while also strengthening its standing among its various stakeholders. We argue that, despite a number of challenges, it is feasible to design and implement a comprehensive, longitudinal study of the development of CT (and related constructs). Although CT is an important learning objective at all colleges, it has special resonance for schools and programs that aim to provide a liberal education. For various reasons we propose that the initial study be conducted within a particular subset of such institutions; namely, a sample of American Jesuit colleges and universities. We discuss a number of technical issues germane to such a study, as well as the advantages and disadvantages of our preferred choice of an institutional sample.
El Habitus académico como generador de resistencias en las profesoras
Authors: Meléndez Ferrer Luis Enrique
Published: July 2021

Las resistencias en profesoras se producen por formas-sentidos que perpetúan el habitus académico. Este abordaje comprende el habitus académico mediante el discurso dominador universitario y en las consciencias colectivas de las profesoras. Este habitus se concreta en resistencias del lenguaje estructural reflejado en significados normativos, filosóficos y pragmáticos alienantes del discurso heteronormativo universitario. El método para construir el ensayo se basó en el análisis documental y hermenéutico. El habitus académico petrifica interacciones sociales, mantiene la dicotomía: objetividad-subjetividad, define al sujeto, fortalece prácticas culturales, entiende el ethos masculino, sincroniza actitudes de profesoras, valora disposiciones morales, descubre la obligación política para ser/actuar, revela el respeto por el status quo de profesoras ante la dominación de la universidad y la profesión académica.

Effect of hydrothermal pretreatment of corn stover with pH adjustment on properties of pulp and hydrolysate
Authors: Kong Junjun , Zhang Ling , Niu Ziyi , Wu Rina , Wang Gaosheng
Published: July 2021

In view of environmental and economic issues, co-production technology with pulp as the major product is an important developmental direction in biorefinery. In this paper, high-yield pulp was prepared by hydrothermal pretreatment with controlled pH and subsequent mechanical refining using corn stover as raw material. By adding acetic acid or sodium hydroxide, the properties of the hydrolysate and the pulp were altered. Reducing the pH during hydrothermal pretreatment resulted in more cellulose and hemicellulose being released, while less lignin was released. Increased pH led to more lignin being released, while dissolution of carbohydrates did not change significantly. A maximum pulp yield at pH 5.84 of hydrolysate was obtained when 3.0% sodium hydroxide was used. The strength of pulp is highly related to the removal of lignin during hydrothermal pretreatment. The relationship between pH value in hydrothermal pretreatment and the physical properties of the pulp was established and could be further used for prediction and as guidance for process control. Moreover, the results could be used to develop technologies for industrial utilization of agricultural straw to co-generate fiber and other bio-based products.

Published: July 2021

The ability of Citrus limon (L.) Burm wood to be used for flooring applications was considered in this work. Selected wood properties were determined, and the response to weathering was tested. Janka hardness, density, screw withdrawal resistance, color, glossiness, and artificial weathering (144, 288, and 432 h) were determined. The wood from Citrus limon was shown to be a dense wood with air density around 830 kg/m3 and with a high Janka hardness of 138.0 N/mm2, 120.4 N/mm2, and 115.9 N/mm2 for cross, tangential, and radial sections, respectively. This opens good perspectives to this kind of wood being used for flooring. Statistical analysis showed that both Janka hardness and screw withdrawal resistance were significantly different between surfaces. Nevertheless, the homogeneity groups showed that the main differences were between the surfaces in the longitudinal direction when compared with the transverse direction. The wood is lighter than most common woods and it is mainly yellow. After weathering, the wood became darker, redder, and yellower. Glossiness decreased in the first hours of the weathering period.
Brewer’s grains with different pretreatments used as bio-adsorbents for the removal of Congo red dye from aqueous solution
Authors: Wu Jianguo , Zhang Zhao , Xu Jintao , Lu Xuanxian , Wang Chi , Xu Hui , Yuan Haihang , Zhang Ji
Published: July 2021

Brewer’s grains (BG), a by-product of the beer industry, were first pretreated by sulfuric acid, sodium hydroxide, and white-rot fungus Coriolus versicolor for the preparation of bio-adsorbents BGPH, BGPOH, and BGPB, respectively. All bio-adsorbents were rich in hydroxyl groups and could adsorb Congo red dye from aqueous solution, and BGPOH worked better than the others. The order of maximum equilibrium adsorption capacity of bio-adsorbents for Congo red was BGPOH > BGPH > BGPB. The Langmuir, Freundlich, and Temkin adsorption isotherm models all fit well with the experimental data. The negative Gibbs free energy change meant that the adsorption was spontaneous, and lower temperature was useful for the adsorption of Congo red onto the bio-adsorbents. The pseudo first-order and second-order kinetics models fit well with the experimental data, and the second-order kinetics model fit better, which indicated the adsorption was controlled by diffusion phenomena. Brewer’s grains with the three pretreatments could be used as efficient adsorbents for the treatment of dye wastewater.

“Professores ideais” e as interações estabelecidas em sala de aula
Authors: Scatolin Patrícia , Silva Ivone Maria Mendes
Published: July 2021

O presente artigo busca identificar as concepções e intencionalidades dos professores a respeito das relações estabelecidas em sala de aula com estudantes adolescentes. Para tanto, três professores indicados por estudantes, de uma turma de nono ano do Ensino Fundamental, como sendo “professores ideais” ou que se aproximam de práticas docentes julgadas como ideais, responderam a um questionário referente à intencionalidade das práticas desses profissionais, bem como as concepções a respeito das relações estabelecidas em sala de aula com os estudantes. A fala dos alunos, assim como as respostas dadas pelos professores, passou por um processo de interpretação inspirada na Análise de Conteúdo de Laurence Bardin, dialogando com estudos teóricos referentes às temáticas da interação em sala de aula, das dimensões profissionais e pessoais da docência, dos aspectos afetivos presentes nas relações estabelecidas entre professores e alunos e a consequente influência na aprendizagem. A análise dos questionários respondidos pelos profissionais, somada aos apontamentos dos estudantes e à discussão teórica, aponta para a presença de três elementos fundamentais: os aspectos técnicos da profissão docente, os aspectos (inter)subjetivos e éticos desse ofício, com destaque à presença da afetividade e a utilização de metodologias variadas. Conclui-se que o discurso dos professores se aproxima, em determinados aspectos, das indicações dos estudantes, mas que ainda há uma grande distância entre as concepções desses profissionais a respeito das interações presentes em sala de aula e a respectiva utilização intencional como potencial facilitador da aprendizagem.

No final do ano de 2019 e ainda em curso no ano de 2020, um vírus altamente contagioso desestruturou os sistemas de saúde, educacionais, econômicos e de produção e tornou-se um desafio sanitário em escala mundial. Com o distanciamento social como medida de enfrentamento, emergiu a problematização desta pesquisa: ‘Como os profissionais da saúde percebem as Tecnologias Digitais e as Mídias Sociais no período da Pandemia da COVID-19 no Brasil?’. A metodologia utilizada foi qualiquantitativa, o instrumento para a coleta de dados foi o Google Forms. Os sujeitos pesquisados foram profissionais da área da saúde, pertencentes as regiões Sul e Sudeste do Brasil. Foram convidados a responder 56 profissionais, entretanto apenas 15 sujeitos responderam à pesquisa. Os resultados demonstraram o uso preponderante do aplicativo WhatsApp e a comunicação virtual possibilitou a manutenção do contato com pacientes e/ou alunos. No entanto há dois olhares perante as Mídias Sociais e as Tecnologias Digitais por esses profissionais, um progressista em relação ao uso dessas ferramentas a partir da pandemia e o outro, de que serão afastadas do cotidiano desses profissionais.

Japanese language and gender research
Authors: Okamoto Shigeko
Published: July 2021

In the past thirty years, major contributions from Japanese language and gender studies have provided necessary insights from the perspective of a non-European language. Future research will demand ever broader approaches – in particular, I call for investigations of the sociolinguistic life of understudied speakers, such as regional Japanese speakers, to examine how they understand linguistic gender norms and deploy a wide variety of linguistic and other semiotic resources for styling diverse forms of gender and sexual identity in situated practice. These questions have profound implications for the relationship between language and gender.
Guiding light in discourse studies
Authors: Hamilton Heidi E
Published: July 2021

This tribute characterises the scholarly life of interactional sociolinguist Deborah Schiffrin (1951–2017), locating her contribution to the 1992 Berkeley Women and Language Conference (‘Gender displays among family, friends, and neighbors: taking the role of another’) within her lifelong exploration of the intricate interrelated workings of language, identity and the world. Debby’s deep understanding of linguistics and sociology undergirded and nurtured nuanced, multidimensional analyses of individual utterances in their connection to systematic patterns within larger communities of practice. Her broad, multifaceted and deep legacy in discourse studies inspires all who seek to examine identity as performed and situated within myriad social worlds and their associated discourses.

Thirty-year retrospective on language, gender and sexuality research
Authors: Hall Kira , Borba Rodrigo , Hiramoto Mie
Published: July 2021

This thirty-year retrospective on language, gender and sexuality research, launched in anticipation of the thirtieth anniversary of the 1992 Berkeley Women and Language Conference, showcases essays by luminaries who presented papers at the conference as well as allied scholars who have taken the field in new directions. Revitalising a tradition set out by the First Berkeley Women and Language Conference in 1985, the four biennial Berkeley conferences held in the 1990s led to the establishment of the International Gender and Language Association and subsequently of the journal Gender and Language, contributing to the field’s institutionalisation and its current pan-global character. Retrospective essays addressing the themes of Politics, Practice, Intersectionality and Place will be published across four issues of the journal in 2021. In this second issue on the theme of practice, Deborah Tannen, Penelope Eckert, Marjorie Harness Goodwin, and Elinor Ochs and Tamar Kremer-Sadlik show how the field’s attention to the micro-details of situated, highly contextualised interaction offers a privileged vantage point for seeing how gender, power and other dimensions of social life emerge as mundane daily actions unfold. Shigeko Okamoto and Marcyliena H. Morgan review how research on the language practices of Japanese and African American women have been formative to the field while also describing the critical necessity of more attention to these areas moving forward. The theme series also pays tribute to significant scholars present at the 1992 Berkeley conference who are no longer with us; in this issue, Heidi E. Hamilton pays homage to the groundbreaking work of Deborah Schiffrin.
The Determinants of Decision-making among Polish, German and Chinese Managers in Managing a Shipping Company in China
Authors: Copp Tomasz
Published: July 2021

Objective: The article specifies the determinants of management decision-making in the shipping industry and examines the similarities and differences in decision-making by Polish, German and Chinese managers managing a shipping company.Research Design & Methods: The research was conducted by means of direct interviews with managers from Poland, Germany and China as well as the observation of participants.Findings: HR, planning, setting priorities and delegating tasks are necessary for effective decisions, as are balance, courage and self-confidence. Cultural differences determine the decisions taken by managers from Poland, Germany and China, who will differ in the solutions that grow out of the decisions management makes. Polish managers more often refer to financial results and decision-making freedom. German managers also count the freedom to adjust their decision-making as a vital factor, as well as the ability to make quick decisions. Chinese managers, meanwhile, more frequently indicate that planning, guidelines, avoiding conflict and good cooperation are the most important factors promoting good decision-making.Implications / Recommendations: The key areas of managerial decisions in the industry include administration, finance, technology, shipping, safety and digitalisation. A manager’s character and system solutions are the most important factors in decision-making.Contribution: The comparison of Polish, German and Chinese managers in the scope of their decision making in shipping companies is a new approach to the shipping industry, one that reveals new knowledge. The results will be the basis for further research and contribute to the development of the discipline.
Industrial frequency multiplier based on a transformer with a rotating field

Published: July 2021

The disadvantage of domestic static converters past generations are the worst dimensions in comparison with rotating converters. Modern inverters use pulse width modulation, which causes problems with electromagnetic compatibility. Imposed by the EU and US sanctions have caused on the agenda of the replacement of imported parts and components, including the search for new ways to develop domestic technology. Known ferromagnetic frequency multipliers have not received applications in industrial energy due to the large mass and low efficiency. Proposed in the article a new method of frequency multiplication solve the above issues, allowing you to implement a simple and reliable converter without the use of imported components. The output voltage of high frequency multiplier is formed by the use of magnetic flux transformer with a rotating field, which has an additional degree of freedom, which is a new solution. Perhaps multiplication with different coefficients of frequency multiplication, including 8 times to provide voltage with a frequency of 400 Hz.
Music-based therapy in rehabilitation of people with multiple sclerosis: a systematic review of clinical trials
Authors: Lopes Josiane , Keppers Ivo Ilvan
Published: July 2021

Abstract Background: Multiple sclerosis (MS) is a major cause of chronic neurological disability in young adults. An increasing number of controlled studies have assessed the potential rehabilitative effects of new drug-free treatments, complementary to the standard care, including music-based therapy (MBT). Objective: To analyze the evidence for the effectiveness of MBT within the therapeutic approaches to individuals diagnosed with MS. Methods: A systematic review of clinical trials was performed with searches in the following databases: BIOSIS, CINAHL, Cochrane, EBSCO, ERIC, Google Scholar, IBECS, LILACS, LISA (ProQuest), Medline, PEDro, PsycINFO (APA), Psychological & Behavioral, PubMed, SciELO, Scopus, SPORTDiscus and Web of Science. Clinical trials comparing MBT versus conventional therapy/no intervention were included. Results: From the 282 studies identified, 10 trials were selected. Among these, the total sample consisted of 429 individuals: 253 were allocated to the experimental group (MBT) and 176 to the control group (conventional therapies or no intervention). All the studies presented high methodological quality. Modalities of MBT were clustered into four groups: (1) Rhythmic auditory; (2) Playing musical instruments; (3) Dance strategy; and (4) Neurological music therapy. Overall, the studies consistently showed that MBT was better than conventional therapy or no intervention, with regard to gait parameters (double support time and walking speed), fatigue level, fatigability, coordination, dexterity, balance, walking endurance, lower extremity functional strength, emotional status and pain. Regarding mental fatigability and memory, the data were conflicting and the evidence was unclear. Conclusion: MBT is a safe and effective approach for clinical rehabilitation of MS patients that leads to positive results regarding both motor and non-motor functions.

ABSTRACT Objective: To analyze the knowledge and practices of education of Family Health Strategy professionals regarding child intoxication for the autonomy and empowering of the families. Methods: Qualitative research, carried out through semistructured interviews with 50 professionals from the Family Health Strategy of a city in the Northwest of Paraná. Data was problematized using Paulo Freire’s sociocultural approach and its concepts of dialogism and autonomy. Results: The statements showed the many ways in which the care for child intoxication is perceived and their relations with educational action, but these were traditional educational practices, with elements focused on the dissemination of information about health-disease, probably because the dialogic approach is still abstract and has no interface with the concrete practices. Final considerations: The education knowledge and practices of the professionals for the autonomy and empowering of families suggested that there is a transition stage between the biomedical model, focused on a cure, and the dialogical one.
