Published: April 2021

The introduction of distance technologies is necessary in the professional training of students, despite various assessments of its effectiveness. Hence the purpose of the study: to develop an upbringing system for students in a distance format and experimentally prove its impact on the main directions of upbringing of future teachers, in comparison with extracurricular activities in full-time mode. 156 undergraduate students took part in the experiment. Experimental research is the author's paradigm for the formation of youth upbringing in extracurricular activities, which includes six synergistically interrelated areas. The upbringing student system developed in the study was tested in two formats of implementation: in full-time format at the first stage of the study and in distance format in the second half of the study. The statistical data obtained during the study confirm the effectiveness of the implementation of extracurricular activities for the formation of the upbringing of future teachers only in full-time format. The introduction of distance technologies in the implementation of upbringing extracurricular activities does not have a positive effect on students, but in some areas has an opposite negative effect. The practical significance of the study is determined by the introduction of a self-analysis and monitoring system into the educational process through the use of Facebook and VKontakte social networks.

Published: April 2021

This paper focuses on research related to the difficulties introduced by academic re-sources management in institutions of Higher Education and specifically in the Fundación Universitaria de Popayán, a private university, where the planning of aca-demic scenarios is performed manually at the beginning of each academic period for an average of 1,776 subjects and suitable location for an average of 8,000 students, which leads to determine the importance of considering a software architecture that theoretically supports software development, physically and logically, allowing de-velopment in a successful and reliable way that reduces errors, costs, and time in the results, specifically for the case study at the Fundación Universitaria de Popayán. Therefore, the research has made it possible to find the need for an architectural vision and a base for the effective development of software, supported by the different views of authors with years of research on the subject. The research itself is supported by the agile design thinking methodology, the basis for meeting the needs of the end user, and where the quality attributes workshop method is included in the prototyping phase, which guarantees to involve stakeholders in advance for the control of quality attributes in the project. This article shows the flaws that arise in the academic scenar-io management process and the importance of establishing, from the architecture and agile methodology, a process that remedies the difficulties of the process performed.

Published: April 2021

Apart from contributing to students’ learning outcomes, learning activities with digital concept maps were useful, fun, and engaging. Kit-Build concept map is a learning framework that incorporated concept map recomposition as its essential activity. It has been used to learn English as a Foreign Language (EFL) reading comprehension. Students learn through recomposing digital concept maps from a set of teacher’s concept map components; hence, the teacher’s concept map is essential in Kit-Build. A teacher’s concept map should reflect the learning context and strategy, the teacher’s purpose and intention, students’ understanding level, and focus questions. However, automatic-generated concept maps with Concept Map Mining (CMM) can only produce general concept maps that are not fit and difficult to correspond to said reasons. As teacher’s concept maps are essential in learning with Kit-Build, improving teachers’ productivity in composing concept maps of a particular learning material becomes necessary. This study proposed a semi-automatic concept map generation approach of EFL reading comprehension texts with CMM to assist teachers composed their concept maps. The proposed concept map generation approach was integrated into the current Kit-Build concept map authoring tool as an authoring support feature. The accuracy of the support feature in generating concept map components is presented in this research. The result suggested that the proposed authoring support tool is better used to refine a concept map.

Published: April 2021

Business Intelligence is very popular and useful for a better understanding of business progress these days, and there are many different methods or tools being used in Business Intelligence. It uses combination of artificial intelligence, data mining, math, and statistic to gain better understanding and insight on the business process performance. As employees have an important role in business process, the desire to have a tool for classifying and predicting their wages are desirable. In this research, we tried to analyzed dataset from Human Resource Department, and this dataset can be used to analyst the data in order to draw a conclusion about whether any employees would prematurely leave the company, and then, a preventive action based on those parameters can be proposed. This is a kind of predictive analytic system which bases on Naïve Bayes, and it can predict whether an employee would leave or stay according to his or her characteristics. But the Naïve Bayes itself does not enough. So we develop a way to solve the problem using uncertain Numeric features classification on it. The accuracy of the result is depended on the amount and effectiveness of the training sets.
An outlook on the evolutionary history of Carabid beetles (Coleoptera, adephaga)
Authors: Brandmayr Pietro
Published: April 2021

The paper is an attempt to take stock of recent research on the evolutionary history of the megadiverse beetle family Carabidae. First, the evolution of the carabid body is presented in its fundamental characteristics, in relation to the thoracic structure and locomotory and morphofunctional constraints, taking into account also what we know about fossil findings. Changes are described in the ten fundamental life forms that are recognizable in the larval body, from primitive surface runner to the arboreal tree/bark dweller and the parasitoid life style. The influence of biotic factors, first of all the food preferences, are examined for the best-known subfamilies/tribes, and a synthetic frame is presented of relationships between prey and age of the lineages in the three types of feeding modes: fluid, fragment and mixed feeders. On the whole, Harpalinae lineages seem more adapted to preys that appeared in recent times after the angiosperm flourishing, though exceptions have found. The availability of the biomasses of social insect nests, ants and termites, was of fundamental importance for several carabid stems. The influence of predators surely contributed to the refinement of chemical defenses, and some avoidance behaviours as gregariousness and müllerian mimcry. Ordering the relevant fossil findings by age and taxon the absence of modern carabid fossils in the first part of mesozoic appears clearly, only in the Cretaceous some extinct forms belonging to the actual suprageneric taxa have been found. Thus, Cenozoic era should be retained the age of modern forms, even if extinct taxa are recorded at least until the late miocene. Concerning the old question of ancestral habitat of adephaga, if terrestrial or aquatic, the intermediate hypothesis of Erwin seems still valid, that is a waterside life on shores rich of animal biomass, from which both directions into inland waters and subaerial ecosystems may have started. Finally, the taxonomic position of Rhysodidae has examined in the light of recent studies. morphology of adult and larval beetles is poorly in accordance with a place in Scaritinae (Clivinini), the preimaginal features remember that of archostemata also in the probable presence of a fused labrum, molecular evidence is mainly indicating a position within Carabidae but still not conclusive. a place as separate family within basal Geadephaga should be maintained.
Description of larvae of Mexican Calosoma Weber, 1801 species, with faunal records (Coleoptera Carabidae Carabini)
Authors: Vigna Taglianti Augusto , Bruschi Sandro , Di Giulio Andrea
Published: April 2021

On the basis of the materials collected on site, the larvae of six species of Mexican Calosoma, namely Calosoma (Callitropa) porosifrons Bates, 1891, and five species of the subgenus Carabomimus Kolbe, 1895 are figured and described for the first time. Though these larvae are quite similar for most characters, some important differences can be found in the two subgenera Callitropa Motschulsky, 1865 and Carabomimus, confirming the distinctness of these taxa. Through an accurate study of the collected adult specimens and of the relevant literature, the distribution of the population afferent to each of these same species is clarified. With the occasion, the distribution of all Mexican Calosoma, is discussed, distinguishing between winged species, usually widely spread, and apterous species, linked to humid, temperate or semi-cold climates. In this context, the distribution of the subgenus Carabomimus, appears to be more sensitive to the influence of geographic barriers and the differentiation of the species was clearly helped by geographic isolation at high altitude in the volcanic massif of central Mexico.

Published: April 2021

Background: Currently available guidelines contain conflicting recommendations on the management of blood pressure (BP) in patients with diabetes mellitus (DM). Therefore, it is necessary to appraise the guidelines and summarize the agreements and differences among recommendations.Methods: Four databases and the websites of guideline organizations were searched for guidelines regarding BP targets and thresholds for pharmacologic therapy in DM patients, and the included guidelines were appraised with the Appraisal of Guidelines for Research and Evaluation (AGREE) II instrument.Results: In 6,498 records identified, 20 guidelines met our inclusion criteria with 64.0% AGREE II scores (interquartile range, 48.5% to 72.0%). The scores of the European and American guidelines were superior to those of the Asian guidelines (both adjusted P<0.001). Most of the guidelines advocated systolic BP targets <130 mm Hg (12 guidelines, 60%) and diastolic BP targets <80 mm Hg (14 guidelines, 70%) in DM patients. Approximately half of the guidelines supported systolic BP thresholds >140 mm Hg (10 guidelines, 50%) and diastolic BP thresholds >90 mm Hg (nine guidelines, 45%). The tiny minority of the guidelines provided the relevant recommendations regarding the lower limit of official BP targets and the ambulatory BP monitoring (ABPM)/home BP monitoring (HBPM) targets and thresholds in DM patients.Conclusion: The lower official BP targets (<130/80 mm Hg) in patients with DM are advocated by most of the guidelines, but they contain conflicting recommendations on the official BP thresholds. Moreover, the gaps regarding the lower limit of official BP targets and the ABPM/HBPM targets and thresholds need to be considered by future study.

Authors: Hu Hong-Wei , Chen Zhi-Guo , Liu Jian-Gang , Chen Gang
Published: April 2021

Traumatic brain injury (TBI) is a serious global public health problem. Survivors of TBI often suffer from long-term disability, which puts a heavy burden on society and families. Unfortunately, up to now, there is no efficacious treatment for TBI patients in clinical practice. As a reducing gas, hydrogen has been shown to be neuroprotective in multiple cerebral disease models; however, its efficacy in TBI remains controversial. In this review, we will focus on the results of hydrogen in experimental TBI, elaborate the potential mechanisms, and put forward for future researches based on our current understanding and views.
Neuroprotective effect of helium after neonatal hypoxic ischemia

Published: April 2021

Neonatal hypoxic ischemia is one of the leading causes of permanent morbidity and mortality in newborns, which is caused by difficulty in supplying blood and oxygen to brain tissue and is often associated with epilepsy, cerebral palsy, death, short-term or long-term neurological and cognitive impairment. In recent years, the clinical therapeutic effects of noble gases have been gradually discovered and recognized. Numerous studies have shown that noble gases have unique neuroprotective effects to restore damaged nerve and relieve symptoms in patients. Although research on the neuroprotective mechanisms of xenon and argon has yielded a lot of results, studies on helium have stalled. Helium is a colorless, odorless, monoatomic inert gas. The helium has no hemodynamic or neurocognitive side effects and can be used as an ideal pre-adaptor for future clinical applications. In recent years, studies have shown that heliox (a mixture of helium and oxygen) pretreatment can protect the heart, brain, liver and intestine from damage in several animal models, where a variety of signaling pathways have been proved to be involved. There are numerous studies on it even though the mechanism of helium for protecting newborns has not been fully elucidated. It is urgent to find an effective treatment due to the high death rate and disability rate of neonatal hypoxic ischemia. It is believed that helium will be approved safely and effectively for clinical use in the near future.

Published: April 2021

Renal cell carcinoma has high propensity for intravascular and lymphatic spread. In one percent of such cases, tumor can reach up to the right atrium. This case reports the postoperative tumor embolization in a patient with renal cell carcinoma. An elderly female underwent a left radical nephrectomy and inferior vena cava (IVC) thrombectomy. She developed atrial fibrillation on the sixth postoperative day following the surgery in the postoperative unit. A bedside transthoracic echocardiogram detected a migrating echo dense structure moving across the tricuspid valve. Following this, she underwent an urgent right atriotomy and extraction of the tumor thrombus through cardiopulmonary bypass. The occurrence of atrial fibrillation in this patient with renal cell cancer in the postoperative period could have possibly been trigerred by a tumor thrombus in the right atrium.
Tracheoinnominate Fistula Due to High-Riding Innominate Artery
Authors: Wankhade Bhushan Sudhakar , Abdel Hadi Ammar Mohamed , Alrais Zeyad Faoor , Kumar Naidu Gopala Arun , Eid Hossameldin
Published: April 2021

Tracheoinnominate fistula (TIF) is a rare but potentially life-threatening complication after tracheostomy. TIF was mostly observed within 7–21 days after tracheostomy but can present even years after tracheostomy. The risk factors for TIF are high cuff pressure, mucosal trauma from malpositioned cannula tip, low tracheal incision, excessive neck movement (hyperextension), radiotherapy, prolonged intubation, and high-riding innominate artery (HRIA). HRIA is also a rare anatomical variation of the innominate artery (IA) whereas IA bifurcates above the sternoclavicular joint. We report a rare case of TIF in a patient with HRIA, who presented with airway bleeding 2 months after percutaneous tracheostomy (PT) and was successfully managed with aggressive resuscitation and midline sternotomy. Knowledge of anatomical variation of the aortic arch and its major branches is essential for the physician who is routinely performing or managing tracheostomy. All the health-care workers involved in the management of tracheostomy should bear this complication in mind while dealing with any airway bleed. We recommend the routine use of bedside neck ultrasonography before all PTs to locate any aberrant vessel within the vicinity of tracheostoma to prevent this complication.

Published: April 2021

Background:

Bulleyaconitine A (BLA) is a diterpenoid alkaloid from the rhizomes of Aconitum bulleyanum Diels and has been clinically used for chronic pain treatment in China for many years. However, the newly reported adverse events of BLA indicated that BLA still has potential safety issues.

Materials and Methods:

To assess the safety of BLA, analgesic tests, acute toxicity studies, repeated-dose oral toxicity studies, and tissue distribution studies after single and repeated administration of BLA were carried out.

Results:

Administration of 0.14 mg/kg BLA showed potent analgesic effects in both analgesic tests. In acute toxicity study, the LD50 value of BLA was calculated to be 3.4434 mg/kg. In the subchronic toxicity study, the no observed adverse effect level was 0.25 mg/kg, and the lowest observed adverse effect level was 0.5 mg/kg. The spleen, liver, and kidneys are newly identified target organs of BLA toxicity after long-term administration. Moreover, unlike a single BLA administration, repeated administration showed BLA redistribution from organs with an abundant blood supply to immune and metabolic organs.

Conclusions:

These results suggested that BLA itself would be nontoxic at a dosage of 0.25 mg/kg in rats and should be carefully used when combining BLA with medications that can cause spleen, liver, or kidney injury.
Conceptual Understanding of Sustainability Among Academic Administrators of Pakistan Public Universities
Authors: Bukhari Syed Kaleem Ullah , Said Hamdan , Mohamad Nor Faizah
Published: April 2021

The transition of higher education institutions (HEIs) from a traditional role to a modern one has focused on the advancement of the innovative idea of sustainability in their functions. HEIs played their traditional role in promoting the disciplinary nature of teaching and research. The modern role of HEIs makes demands for not only knowledge to be promoted but also for the gap between academia and society to be bridged. This modern role is a fundamental principle of sustainability. Lack of understanding of the concept of sustainability causes hurdles in taking sustainable initiatives. The status of sustainability in Pakistan is in its infancy phase and poorly documented. It is due to the lack of conceptualizing sustainability that is underestimated and unexplored. This study explored how Pakistan Public Universities’ (PPUs) academic administrators conceptualize sustainability, universities’ role in promoting sustainability, and factors supporting or hindering sustainability. A qualitative approach was employed to conduct this study. Data were generated using semi-structured interviews and document analysis. A conceptual framework, comprising the role of universities, barriers and favourable factors to sustainability was used to analyse the data. Interviewees’ responses and documents were meticulously transcribed, read, re-read and coded and findings were presented in thematic form based on the conceptual framework. The study found that academic administrators were aware of the subject of sustainability but faced more constraints than incentives to promote sustainability. The study also found that PPUs are transforming partially into modern role. The findings indicated lack of interest and commitment from top leadership in engaging stakeholders and creating supportive environment to understand sustainability. The findings point out a serious need for concerted efforts from relevant stakeholders to comprehend and embed sustainability in HEIs functions.
Older Adults—Their Focus on Food and Future Living: A Grounded Theory Approach
Authors: Hansen Kai Victor
Published: April 2021

Older adults, also known as the silver generation, are the new healthy generation. This generation has for many decades formed the basis for the prosperity found in Norway. The ageing population is growing rapidly in many countries around the world. The aim of this paper is to understand healthy active older adults’ interpretations of food and meals and their focus on food and future living. Nine CurroCus® group interviews, or fast focus groups, were conducted, lasting 37 to 56 minutes with an average of 45 minutes. Altogether, 76 persons from both genders participated, with an age span of 60 to 87 years, although participants were predominantly female (80%). The main findings indicated that older adults expect good overall experiences at nursing homes, including food and drink with good standards adapted to the individual’s needs and smaller apartments with common rooms for activities; they also actively use technology in their everyday lives. Future research should focus on areas such as user interaction strains around food in nursing homes and home residents, various measures for enabling the elderly to stay at home longer, and the mapping of combinations of food and medicines. In addition, different types of housing units should be better investigated.
Using Self-Assessment to Build Self-Efficacy and Intrinsic Motivation in Athletes: A Mixed Methods Explanatory Design on Female Adolescent Volleyball Players
Authors: Knight Allan
Published: April 2021

The aim of this mixed-methods study was to address the issue of burnout and lack of motivation in middle and high school student-athletes. As young athletes cope with school and stresses of extracurricular activities, they often react negatively to external feedback and motivation. The athletes often find themselves in a low state of self-efficacy due to perceived external pressures. This can lead to burnout and ultimately quitting the sport. This study utilized a model that was designed to use self-assessment to increase self-efficacy among athletes to promote a higher sense of accomplishment and motivation toward success. The athletes were all female volleyball players ranging from ages 10-18. Each athlete received a pretest to ascertain her level of motivation prior to the beginning of the athletic season. During their athletic seasons, 30 of the athletes participated in a weekly self-assessment program producing measurable quantitative data to be used as predictors. A sample selection of the athletes was also interviewed to allow for reflection on the study and produce qualitative data intended to predict possible outcomes of the study. Upon completion of the season the athletes took a post-test to measure their levels of motivation. The outcome of the study produced a statistical effect that demonstrated an increase in self-efficacy and self-determination in athletes, and subsequently increased motivation. The qualitative interview data corroborated the effect produced by the quantitative data.
The Experiences of Parents and Facilitators in a Positive Parenting Program
Authors: Stenason Lauren , Moorman Jessie , Romano Elisa
Published: April 2021

The researchers examined facilitators’ and parents’ experiences with the Positive Discipline in Everyday Parenting (PDEP) program through qualitative methodology. PDEP is a primary prevention program that teaches parents to move away from physical punishment and toward conflict resolution and positive parenting that focuses on stages of child development. Using a phenomenological approach, we conducted focus groups using semi-structured interviews with four PDEP facilitators and seven parents who completed the program. Parents and facilitators indicated that PDEP helped them learn new ways of thinking about parenting and contributed to overall changes in their parenting approach, including finding a balance of structured and sensitive parenting practices. Factors that contributed to positive experiences included the coherence and continuity among program modules, use of concrete examples to demonstrate concepts, supportive facilitators and fellow group members, and the provision of childcare. Suggestions for program improvement included the use of even more concrete examples to demonstrate parenting concepts, longer program duration, and greater flexibility in program delivery. These findings are important for further adaptations to the PDEP program. These findings may also be generalized to parenting programs that share similar core principles.
Learning to Teach in Diverse Schools: Two Approaches to Teacher Education
Authors: Anderson Ashlee , Aronson Brittany
Published: April 2021

With this paper, we explore two approaches to teacher education, paying attention to how teachers are prepared to work in diverse school settings in a time of increasingly competitive neoliberal, market-based reform. These two approaches reflect completion of a traditional teacher education program and completion of Teach for America (TFA). The findings are based on two independent interview studies that are informed by the researchers’ joint commitments to postcritical ethnography, which consider issues associated with positionality, reflexivity, objectivity, and representation. The first interview study engaged teachers who graduated from a traditional teacher education program, as well as two participants with a more specialized urban focus. Interview questions asked teachers to describe their implementation of culturally relevant pedagogy in their classrooms and how prepared they were to do so. The second study addressed the experiences of TFA alumni as they matriculated through the program, with special emphasis being paid to the support that each corps member received during and immediately following their tenure.
Contemporary Japanese Career Women: Reflections on Profession, Life, and Purpose
Authors: Aronsson Anne
Published: April 2021

In this article, I explore what motivates Japanese women to pursue professional careers in today’s neoliberal economy and how they reconfigure notions of selfhood while doing so. I ask why and how one fourth of Japanese women stay on a career track, often against considerable odds, while the other three fourths drop out of the workforce. Employment trends indicate that more white-collar professional women are breaking through the “glass ceiling” and more women are now filling managerial posts. These trends have been supported by the recession, which has led to the liberalization of career paths that fit with women’s tendencies to engage in short-term and part-time work. Through snowball sampling, I carried out in-depth interviews with thirty-eight women in their forties for eighteen months (between 2007 and 2010), and I conducted follow-up interviews with a selected group of these women (between 2014 and 2018). The women in this group had been in their careers long enough to be able to look back on their professional and private experiences. As I show in this article, the forties appear to be a turning point, because this age represents their first opportunity to take the time to reflect on their careers and to redress the imbalance between their professional and private lives.
“Compassionate Dictatorship”: Leading Old Singers in Community Choirs in Australia
Authors: Joseph Dawn , Southcott Jane
Published: April 2021

In Australia, the ageing population generate challenges, pressures and opportunities for both governmental and community organisations. Involvement in community choirs offers older people diverse benefits that increase with ongoing participation. The music directors/conductors (MD/C) of community choirs are pivotal in the success of ensembles. This paper forms part of our wider study into Well-being and ageing: community, diversity and the arts in Victoria, Australia and addresses the questions, how do music directors/conductors (MD/C) of community choirs understand working with older people? And, how do older choir members understand the role of their MD/C? We interviewed two MD/Cs and thematically analysed our data. We present our findings under two overarching themes that evolved from our data analysis: Understandings of working with older people in a choir and musical leadership in a community setting. We found that the MD/Cs are reflective practitioners who imbued their facilitation and conducting with enthusiasm, skill, knowledge and passion for musical engagement. Our research suggests that to ensure longevity of choirs and to recognise the contribution of MD/Cs, greater attention should be paid to the upskilling of future generations of MD/Cs.
Assessment of Agricultural Advisory Messages from Farmer-to-Farmer in Making a Case for Scaling Up Production: A Qualitative Study
Authors: Kwapong Nana Afranaa , Ankrah Daniel , Boateng-Gyambiby Dominic , Asenso-Agyemang Joseph , Oteng Fening Lydia
Published: April 2021

Inadequate access to agricultural extension services often results in poor farm practices, affecting yields and subsequently the income and wellbeing of smallholder farmers. Given the high demand for agricultural information and the limited capacity of extension services, a farmer-to-farmer extension approach has been explored by many underserved farmers. In this study, we use a qualitative case study approach explore how cassava farmers who had limited access to agricultural advisory services from public extension agents managed to up-scale their farming business. Our research question was: what lessons can be learned from the lived experience of these farmers to address current challenges of cassava farming? The results of our study revealed diversity in advisory messages from farmer to farmer and agricultural extension agents. Farmers’ messages focused on encouraging farmers’ commitment and motivation towards farming business, availability of needed financial resources for the entire production season, willingness to reinvest profits, and access to farmland for future expansion. In contrast, the traditional messages from agricultural extension agents focused on encouraging group formation to address marketing challenges, diversification of farm operations, and good agricultural practices. These results show the need for pluralistic extension approaches to ensure farmers get access to necessary information.
How Do They Feel About It? Testing a New Mixed Methods Survey Tool to Assess Collective Emotional Status
Authors: Schwab Michael , Margaritis Vasileios
Published: April 2021

Emotions are now widely accepted as important elements of qualitative research, in studies of individuals and communities. However, collective emotional status—what a community feels about a given situation or proposition—can be challenging to assess. In this study, we examined the validity and acceptability of a new mixed methods survey tool, primarily qualitative, to address this challenge—the Assessment of Collective Emotional Status (ACES). The tool begins with an adjustable set of questions about emotion, to draw respondents’ attention to their own feelings. These are followed by an emotional self-assessment, in which respondents select and prioritize five emotional responses to a standardized stimulus, drawing from a new taxonomy of emotion words. In this study, the stimulus was a proposition that gun violence should be approached as a public health problem. We tested the tool in an international survey of public health professionals, mostly in the US and Europe (n=160). Qualitative and quantitative data were collected on knowledge and importance of emotion, adequacy of the taxonomy, emotional responses to the stimulus, and use of the tool. Scores were high for knowledge and importance of emotion. Perceived adequacy of the taxonomy was also high, especially with Black and Hispanic respondents, signifying good construct validity. The total weighted frequency of emotions in response to the stimulus was highest for encouraged (92.2%), open (78.8%), hope (77.2%) and interest (77.2%). Qualitative data yielded six themes—on knowledge of emotion, the taxonomy, responses to the stimulus, and use of the tool, which many respondents found easy and interesting to use. This study demonstrates the prima facie validity and acceptability of the ACES with an educated adult population.
Contentment or Torment? An Analytic Autoethnography of Publication Aptitude in Doctor of Philosophy
Authors: sm-Rahman Atiqur , Jahan Yasmin
Published: April 2021

The burgeoning trend of pursuing publication in a leading journal, as a benchmark of standard doctoral research, has become an appealing expectation of early-stage doctoral researchers (ESDR). However, recent pedagogical studies showed limited attention to exploring the dynamic relations between doctoral education and the academic publication process. Our aim was to investigate and understand (if and) how this intricately intertwined relation contributes to the scholarly publication practice in doctoral education from an individual and institutional context. We used a duo-analytic autoethnography approach and presented a comprehensive narrative based on the authors’ self-reflections by using a range of data sources namely research diaries, journaling, seminars, training courses, online forum talking, and web-based open sources. Through our autoethnographic narrative, we found five key aspects associated with publication practices in doctoral programs: quality-quantity debate, authorship dilemma, journal selection process, publishing in leading journals, and publication process. We additionally mapped out a conclusive publication cycle to demonstrate how dominant structural factors of the doctoral program subsequently affect the publication process, influence ESDR’s decision-making, and potentially reinforce academic pressures. Based on our study findings, we concluded that doctoral education should remain research intensive rather than a simplified way of obtaining a higher academic qualification.
Finding a Good Book to Live In: A Reflective Autoethnography on Childhood Sexual Abuse, Literature and the Epiphany
Authors: Barley Karen
Published: April 2021

The topic of Childhood Sexual Abuse (CSA) remains a prevalent issue globally and despite the best efforts of welfare organisations, it would seem that as a society we are no closer to a resolution. CSA is a topic that is discussed in vague terms, but the real impact of CSA on the child is rarely divulged, except behind closed doors. This autoethnographic study traces the life and experiences of CSA of the author and how she used literature and writing as a coping mechanism. Using this powerful methodological tool, the author has been able to expose the implications of the sexual abuse and the use of writing as a place to hide and feel safe. The value of autoethnography is illuminated by demonstrating that poignant and potent data can be collected and then shared in a way that has more impact than other research methods. Second, the value of the researcher as the researched can be viewed as an authentic way of analysing difficult and taboo societal issues such as CSA, where hopefully the results can lead to more insightful and honest discussions about how to confront this problem.

Not all people with disabilities are provided with assistive technologies and devices (ATD) they need. The Russian researchers appeal to the development of assistive technologies, however, focus only on one specific social objective of ATD provision or on engineering, economic and production aspects of the problem. This study identifies the key determinants of the development of the assistive technologies market in Russia and trends over the next 10–15 years. We conducted a qualitative study using a grounded theory based on open and axial coding procedure. We collected data using semi-structured interviews with 12 experts recruited through snowball sampling with multiple entry points. The results show that the focus on the development of individual rehabilitation programs, individual fitting of devices, the increasing demand for measures of medical and social support for people with disabilities create conditions for the growth of demand for ATD. Changes in the paying capacity of the population, the rules of budget financing, as well as the population's attitude towards the inclusion of people with disabilities in everyday activities, the labor market, education will also cause changes in demand for ATD.

Entre fevereiro de 2009 a junho de 2012, 368 espécimes de nove espécies de peixes marinhos (Osteichthyes) coletados ao longo da costa do Estado do Rio de Janeiro (21° - 23° S, 41° - 45° W), foram necropsiados para estudar sua fauna parasita de Copepoda e Isopoda. Foram identificadas 11 espécies de copépodes e três espécies de isópodes parasitos. Sendo coletados 852 espécimes de copépodes e quatro de isópodes. O mais prevalente e abundante dentre os crustáceos parasitos foi Taeniacanthus lagocephali Pearse, 1952, enquanto Coryphaena hippurus Linnaeus, 1758 foi a espécie de hospedeiro com a maior diversidade de espécies de ectoparasitos. Os gêneros Ceratothoa Dana, 1852 e Mothocya Hope, 1851 são registrados pela primeira vez para o Brasil neste estudo.
A Ferramenta "Tabulação SIC" e sua influência na Ação Projetual e na Gestão de Sistemas Complexos
Authors: Santos Marcello Silva e , Nascimento Alessandra Reis
Published: April 2021

Projetos de salas de controle de refinarias envolvem a combinação de grande número de variáveis e especificidades que fazem com que os mesmos sejam complexos, não apenas em sua natureza como no seu tratamento. Em outras palavras, deve-se trabalhar a ação projetual de forma integrada, associando especificações técnicas, exigências de segurança e ambientais, além de necessidades particulares da organização do trabalho nesse tipo de ambiente construído. A ergonomia, portanto, aqui entendida como a disciplina científica que busca adaptar os sistemas de trabalho às necessidades humanas, é um importante componente dessa equação, agregando qualidade ao projeto. Entretanto, necessidades, prioridades e requisitos operacionais devem ser ponderados cuidadosamente em função dos usuários. Este artigo aborda a utilização de uma ferramenta de priorização, desenvolvida em conjunto pelo UniFOA e o Laboratório GENTE, da COPPE/UFRJ. A Tabulação SIC é uma ferramenta que auxilia e priorização dos requisitos de ergonomia na definição das anotações de projeto que devem ser incorporadas no projeto executivo.
Effect of ultraviolet radiation on the skin

The beneficial effect of ultraviolet radiation on our skin manifests itself in the synthesis of vitamin D. However, the detrimental effect of this radiation is much more severe. A longer duration of the effect of this radiation speeds up photoaging of skin depending on its phonotype. Symptoms of burning accompanied by tiredness, headaches, changes in temperature, skin damage observed testify to the negative effect of ultra-violet radiation. The unsuitable acquisition of measures of protection with SPF (Sun Protection Factor) numbers and their seasonal application presuppose the formation of wrinkles. This issue remains relevant today as well, because the results of ultraviolet radiation are diagnosed ever more often. They testify to careless skin care. The slightest skin redness, swelling or brownness is reaction of the skin to harmful ultraviolet radiation. The aim of the investigation was to examine the effect of ultraviolet radiation on skin. The investigation was carried out in virtual space on the Internet website www.apklausa.lt in 2021 (2 months). A total of 209 respondents took part in the investigation. The results and conclusions of the investigation are as follows: due to the nature of work, about half of the respondents were exposed to ultraviolet radiation the whole day or 3–4 hours a day. One the third of the respondents used the solarium procedures once per week, provided themselves with measures of protection in shops; however, they did not set great store by the protective effect of SPF filters. One the sixth of the respondents used measures of protection when their skin suffered serious damage.
Sectoral Approach in Output Growth Decomposition and its Determinants in Europe
Authors: Bacovic Maja
Published: April 2021

The structural changes in Europe have occurred over the last several decades, reducing output share in the goods sector, while increasing its share in overall services. Applying the growth accounting approach, we decomposed output growth in the economy while following the sectoral approach, in ten individual sectors in twenty-six European countries, from 2000 to 2019. Our analysis shows that total factor productivity has accounted for almost half of the European countries growth in output in the last two decades, with the other half primarily accounted for by increases in fixed asset growth and employment growth, while its variations among sectors are significant. The output growth in the services sector is significantly more driven by employment growth than in the goods sector, leading to overall employment growth in the economy. Applying the panel pooled OLS model, we found that the relevance of expenditures for research and development is high and positive in all sectors, but higher in industry and knowledge-intensive services (information and communication, scientific activities) compared to all sectors average. To the best knowledge of the author, this is the first study presenting output growth decomposition estimates at the sectoral level for a selected group of countries, but also the first study presenting estimates of TFP in the total economy for a selected time periods. In addition, this is the first study that presents the relevance of investment in research and development at the sectoral level in this specific time period and group of countries. Results of the study may be used in defining national policies priorities, as there are varieties among sectors in terms of their impact on employment and economic growth.
