Considerations and Perspectives on Interventions to Improve Social Cognition in Adolescents With ASD Without ID: Involving Parents in Social Skills Groups
Authors: Vuattoux Delphine , Castiglia Deborah , Chabane Nadia
Published: May 2021

Improving social cognition and social skills is a challenge faced by individuals with Autism Spectrum Disorder without Intellectual Disability at any age. This process is particularly critical during late adolescence (15–18 years), a developmental phase generally characterized by rich social experiences that usually foster the development of friendships. Nevertheless, for youth with ASD, lingering difficulties in social cognition often hinder their ability to generate responses considered socially appropriated. These social deficits can contribute to isolation that has a detrimental effect on mental health. In adulthood, deficits of social skills are strongly associated with an overall lack of support, characterized by a failure to integrate into the labor market, a high unemployment rate, social isolation, and a higher suicide rate. In clinical settings, social skills groups are well-established therapeutic means to improve social cognition and social skills. Nevertheless, these interventions vary greatly regarding their objectives, contents and duration. Moreover, few have been validated and replicated by research. Our aim is to bring certain perspectives to a type of intervention that are widely used in care settings. After reviewing its positive aspects for increasing social cognition, and its limitations, we will discuss strategies to facilitate the generalization of social skills in an ecological context. In particular, we will base our reflection on our clinical experience and on our current project to adapt the PEERS model for adolescents into French. We will consider the current trend of involving parents as “social coaches” to generalize the social knowledge acquired in the social skills groups.

Published: May 2021

Background and Objective: Frontline healthcare workers face unprecedented stress from the current SARS COV-2 (COVID-19) pandemic. Hospital systems need to develop support programs to help frontline staff deal with this stress. The purpose of this article is to describe a support program for front line healthcare workers.

Methods: In this community case report, we describe a well-being support rounding program that was developed to deliver Psychological First Aid (PFA) to frontline healthcare workers in a large urban medical center to maintain their sense of psychological well-being and self-efficacy. A team of clinicians from the department of psychiatry, who were trained on the Johns Hopkins RAPID model (Reflective Listening, Assessment, Prioritization, Intervention, and Disposition) to provide PFA, were deployed throughout the hospital. These clinicians carried out daily well-being rounds from April to June during the peak of the pandemic.

Results: Approximately 20% of the frontline staff members were going through an acute crisis and benefited from PFA. Anxiety, anger, exhaustion, economic worry, job insecurity, dehumanized interactions with patients due to Personal Protective Equipment (PPE), and stress of taking care of sick and dying patients without their families present, were the main themes identified by the staff. The deployed team used active listening, mindfulness, validation, reframing and other cognitive interventions to support staff.

Conclusions: Our experience suggests that frontline staff are willing to engage with in-person, on-site support programs. Fostering resilience and self-efficacy through PFA is a useful model to provide emotional support to frontline healthcare workers during health crises.

Background: Suicide is a common and complex symptom of schizophrenia that may be related to clinical variables and neurocognitive function. This study aimed to investigate the associated correlates of suicide attempts in Chinese middle-aged and elderly inpatients with schizophrenia, including demographic and clinical characteristics and cognitive level, which has not yet been reported.

Methods: A total of 426 schizophrenia inpatients were recruited for this study. Clinical symptoms were evaluated using the Positive and Negative Syndrome Scale (PANSS). Neurocognitive function was measured by the Repeatable Battery for the Assessment of Neuropsychological Status (RBANS).

Results: The prevalence of suicide attempts in middle-aged and elderly Chinese schizophrenia patients was 13.3%. Female patients had a higher suicide rate than male patients. Patients with suicide attempts had significantly higher PANSS-positive subscores, depressive subscores, and RBANS-story recall than non-attempter patients (all p < 0.05). Multiple logistic regression showed that gender, positive subscore, depressive subscore and RBANS-story recall (OR = 1.10–2.19, p < 0.05) were independently associated with suicide attempts in middle-aged and elderly schizophrenia patients.

Conclusions: Our study showed that the rate of suicide attempts in Chinese middle-aged and elderly schizophrenia patients is high. Compared to non-attempters, there are less cognitive impairments, more clinical symptoms, and more female patients in the suicide attempters.

Published: May 2021

In the United States, single smokeless tobacco use continues to increase in conjunction with the dual use of smokeless tobacco and other nicotine products. Problematically, much of the tobacco prevention literature and funding inundates tobacco users with smoking tobacco information while neglecting to provide them any information about smokeless tobacco. Meanwhile, American tobacco companies continually market new and dissolvable tobacco products targeted at non-smokers. New data suggests that smokeless tobacco use is, also, increasing in West Virginia and, in order to address this increased use, the West Virginia Extension Service recently partnered with the Division of Tobacco Prevention in the West Virginia Department of Health and Human Resources to develop a comprehensive spit tobacco curriculum for West Virginia students between third and sixth grade. This article details the development and assessment of the spit tobacco prevention curriculum and the resulting report from the initial pilot of the program. The curriculum was piloted across six counties with the participation of schools, after-school programs and 4-H clubs. After implementation, survey results demonstrate that youth have increased awareness of the health effects of smokeless tobacco. Throughout the article, we explore West Virginia's Cooperative Extension Service's response to this emerging public health issue and release a call to action for the National Cooperative Extension Services to join us in spit tobacco prevention.

Published: May 2021

While technological advances in radiation oncology have led to a more precise delivery of radiation dose and a decreased risk of side effects, there is still a need to better understand the mechanisms underlying DNA damage response (DDR) at the DNA and cytogenetic levels, and to overcome tumor resistance. To maintain genomic stability, cells have developed sophisticated signaling pathways enabling cell cycle arrest to facilitate DNA repair via the DDR-related kinases and their downstream targets, so that DNA damage or DNA replication stress induced by genotoxic therapies can be resolved. ATM, ATR, and Chk1 kinases are key mediators in DDR activation and crucial factors in treatment resistance. It is of importance, therefore, as an alternative to the conventional clonogenic assay, to establish a cytogenetic assay enabling reliable and time-efficient results in evaluating the potency of DDR inhibitors for radiosensitization. Toward this goal, the present study aims at the development and optimization of a chromosomal radiosensitivity assay using the DDR and G2-checkpoint inhibitors as a novel modification compared to the classical G2-assay. Also, it aims at investigating the strengths of this assay for rapid radiosensitivity assessments in cultured cells, and potentially, in tumor cells obtained from biopsies. Specifically, exponentially growing RPE and 82-6 hTERT human cells are irradiated during the G2/M-phase transition in the presence or absence of Caffeine, VE-821, and UCN-1 inhibitors of ATM/ATR, ATR, and Chk1, respectively, and the induced chromatid breaks are used to evaluate cell radiosensitivity and their potency for radiosensitization. The increased yield of chromatid breaks in the presence of DDR inhibitors, which underpins radiosensitization, is similar to that observed in cells from highly radiosensitive AT-patients, and is considered here as 100% radiosensitive internal control. The results highlight the potential of our modified G2-assay using VE-821 to evaluate cell radiosensitivity, the efficacy of DDR inhibitors in radiosensitization, and reinforce the concept that ATM, ATR, and Chk1 represent attractive anticancer drug targets in radiation oncology.
Embedding Virtual Reality Technology in Teaching 3D Design for Secondary Education

Published: May 2021

As a new medium in modern education, virtual reality technology has stimulated the changes of pedagogical practice and added further opportunities for experiential learning. The immersive and interactive experience of VR fits seemingly well with practical subjects such as Creative Design. Design-related courses in secondary education usually appeal to the students with their practical elements, which also help in developing a student's creative and cognitive ability. The dual coding learning theory states that the learning process can be improved by using the symmetrical visual and language systems of the left and right hemispheres. This paper presents a novel teaching framework that combines classroom learning with VR technology. We devise the course structure based on Bloom’s Taxonomy and fill in knowledge and skills related to 3D Design. In collaboration with a local school, we implemented and delivered the proposed course to a group of students. After the course, we use questionnaires and interviews to collect and analyze the attendees’ feedback. The results show that the interactive experience in VR coincides better with the students’ perception of 3D conceptual design. The teaching methods are also well-received by them. Based on the findings, we suggest that immersive VR technology is a promising tool for developing practical courses such as product design and development.
Effect of Binding Energies on the Encounter Desorption

Published: May 2021

The abundance of interstellar ice constituents is usually expressed with respect to the water ice because, in denser regions, a significant portion of the interstellar grain surface would be covered by water ice. The binding energy (BE) or adsorption energy of the interstellar species regulates the chemical complexity of the interstellar grain mantle. Due to the high abundance of water ice, the BE of surface species with the water is usually provided and widely used in astrochemical modeling. However, the hydrogen molecules would cover some part of the grain mantle in the denser and colder part of the interstellar medium. Even at around ∼10 K, few atoms and simple molecules with lower adsorption energies can migrate through the surface. The BE of the surface species with H2 substrate would be very different from that of a water substrate. However, adequate information regarding these differences is lacking. Here, we employ the quantum chemical calculation to provide the BE of 95 interstellar species with H2 substrate. These are representative of the BEs of species to a H2 overlayer on a grain surface. On average, we notice that the BE with the H2 monomer substrate is almost ten times lower than the BE of these species reported earlier with the H2O c-tetramer configuration. The encounter desorption of H and H2 was introduced [with ED(H,H2)=45 K and ED(H2,H2)=23 K] to have a realistic estimation of the abundances of the surface species in the colder and denser region. Our quantum chemical calculations yield higher adsorption energy of H2 than that of H [ED(H,H2) = 23–25 K and ED(H2,H2) = 67–79 K]. We further implement an astrochemical model to study the effect of encounter desorption with the present realistic estimation. The encounter desorption of the N atom [calculations yield ED(N,H2)=83 K] is introduced to study the differences with its inclusion.
Greening Sport for Development and Peace: A Socio-Ecological Approach
Authors: Giulianotti Richard
Published: May 2021

The global “sport for development and peace” (SDP) sector uses sport as a field of social activity to promote diverse types of non-sport social development. In this short perspective article, I critically examine and advocate the engagement of SDP with environmental issues. I argue for the adoption of a “socio-ecological” approach, to enable a greening of SDP that promotes both environmental and social justice. To that end, the article is organized into four main parts. First, I situate the discussion with respect to key literature on SDP and the environment. I then outline some of the main contextual factors that need to be considered on sport, development, and the environment. Third, I set out several core principles that should underpin the socio-ecological greening of SDP. Fourth, I examine how these principles may be implemented within SDP.
Effect of Carbohydrate Content in a Pre-event Meal on Endurance Performance-Determining Factors: A Randomized Controlled Crossover-Trial
Authors: Aandahl Mats Holst , Noordhof Dionne A. , Tjønna Arnt Erik , Sandbakk Øyvind
Published: May 2021

The current study aimed to investigate the effect of the relative CHO content in a pre-event meal on time to exhaustion (TTE), peak oxygen uptake (V∙O2peak), the 2nd lactate threshold (LT2), onset of blood lactate accumulation (OBLA), and work economy (WE) and to compare responses between well-trained and recreationally trained individuals. Eleven well-trained and 10 recreationally trained men performed three trials in a randomized cross-over design, in which they performed exercise tests (1) after a high-CHO pre-event meal (3 g · kg−1), (2) a low-CHO pre-event meal (0.5 g · kg−1), or (3) in a fasted-state. The test protocol consisted of five submaximal 5-min constant-velocity bouts of increasing intensity and a graded exercise test (GXT) to measure TTE. A repeated measure ANOVA with a between-subjects factor (well-trained vs. recreational) was performed. A main effect of pre-event meal was found (p = 0.001), with TTE being 8.0% longer following the high-CHO meal compared to the fasted state (p = 0.009) and 7.2% longer compared to the low-CHO meal (p = 0.010). No significant effect of pre-event meal on V∙O2peak, LT2, OBLA, or WE (p ≥ 0.087) was found and no significant interaction effect between training status and pre-event CHO intake was found for TTE or any of the performance-determining variables (p ≥ 0.257). In conclusion, high-CHO content in the pre-event meal led to a longer TTE compared to a meal with a low-CHO content or exercising in a fasted state, both in well-trained and recreationally trained participants. However, the underlying physiological reason for the increased TTE is unclear, as no effect of pre-event meal on the main physiological performance-determining variables was found. Thus, pre-event CHO intake should be standardized when the goal is to assess endurance performance but seems to be of less importance when assessing the main performance-determining variables.

The pathophysiology of Horner's syndrome arises due to compression or destruction of the oculosympathetic nerve pathway. Traumatic Horner's syndrome may indicate lethal neurovascular injury, such as brain stem lesion, cervical spine injury, or carotid artery dissection. The middle-third is the most common type of clavicle fracture. However, the association of the isolated middle-third clavicle fracture and Horner's syndrome is rare. We report the case of a 47 year-old woman who presented to our emergency department with acute trauma. Severe tenderness and limited mobility were observed in her left shoulder. On radiographic examination, a middle-third clavicle fracture was diagnosed. Ptosis and myosis were also noticed on further examination, and she was subsequently diagnosed with Horner's syndrome. A survey of the brain, cervical spine, carotid artery, and lung revealed no pathological findings. Surgery for the clavicle fracture was performed 2 days after the accident. The patient recovered from Horner's syndrome gradually over the 2 months following the surgery, and the syndrome completely resolved by the third month. To the best of our knowledge, this is the first report of traumatic Horner's syndrome caused by an isolated middle-third clavicle fracture. The improved outcome may be attributed to the surgical intervention for middle-third clavicle fracture, which may help release ganglion or neuronal compression.

The ruminant gut microbial community's importance has been widely acknowledged due to its positive roles in physiology, metabolism, and health maintenance. Diarrhea has been demonstrated to cause adverse effects on gastrointestinal health and intestinal microecosystem, but studies regarding diarrheal influence on gut microbiota in Giraffa camelopardalis have been insufficient to date. Here, this study was performed to investigate and compare gut microbial composition and variability between healthy and diarrheic G. camelopardalis. The results showed that the gut microbial community of diarrheal G. camelopardalis displayed a significant decrease in alpha diversity, accompanied by distinct alterations in taxonomic compositions. Bacterial taxonomic analysis indicated that the dominant bacterial phyla (Proteobacteria, Bacteroidetes, and Firmicutes) and genera (Escherichia Shigella and Acinetobacter) of both groups were the same but different in relative abundance. Specifically, the proportion of Proteobacteria in the diarrheal G. camelopardalis was increased as compared with healthy populations, whereas Bacteroidetes, Firmicutes, Tenericutes, and Spirochaetes were significantly decreased. Moreover, the relative abundance of one bacterial genus (Comamonas) dramatically increased in diarrheic G. camelopardalis, whereas the relative richness of 18 bacterial genera decreased compared with healthy populations. Among them, two bacterial genera (Ruminiclostridium_5 and Blautia) cannot be detected in the gut bacterial community of diarrheal G. camelopardalis. In summary, this study demonstrated that diarrhea could significantly change the gut microbial composition and diversity in G. camelopardalis by increasing the proportion of pathogenic to beneficial bacteria. Moreover, this study first characterized the distribution of gut microbial communities in G. camelopardalis with different health states. It contributed to providing a theoretical basis for establishing a prevention and treatment system for G. camelopardalis diarrhea.

Published: May 2021

Objective:To describe the inequalities in the double burden of malnutrition (DBM) in the adult population.

Methods:Study carried out with data from the VIGITEL study, conducted in 2019 in all Brazilian capitals. Underweight and excess weight were evaluated on the basis of years of schooling and age. Multi-level analysis was performed including Human Development Index of each capital and individual-level variables. The inequality slope index was used to assess the magnitude of the inequalities found. All analyses considered the svy command owing to the complexity of the sampling process.

Results:47.119 individuals were studied. Men with no education had 6 percentage points more underweight compared to those with higher education. Higher prevalence of excess weight was found among men with higher education and women with no education. In women, the difference was 18 percentage points between extreme categories. Elderly people with no education had 10 percentage points more excess weight than those with higher education.

Conclusions:The findings suggest the need for intersectoral actions that can cope with the social inequalities and help confronting with the DBM in Brazil.

With Mars colonisation becoming a reality for the near future, it is of importance to analyse how crew and cargo can be transported between Earth and a colony on Mars. This article is a feasibility and design study of a launch vehicle whose mission is to shuttle crew and cargo from Low Mars Orbit to a colony on the Martian surface. A single-stage reusable rocket has been selected to fulfil this mission, code-named Charon. The mission profile of such a vehicle was created, leading to a Maximum Growth Allowance (MGA) Delta-V budget of 6.2 km/s. With the mission profile in mind, each subsystem underwent a preliminary design. With reliability and maintainability in mind, subsystems were designed for redundancy and modularity, and an abort system was included for an added level of safety. The iterative design process resulted in a vehicle with a MGA mass of 198.7 tons, capable of transporting 1200 kg of cargo and a crew of 6 people to a 500 km orbit and back. The preliminary design of the vehicle is deemed safe. Following a fault tree analysis, the Single Launch Loss of Mission, Vehicle and Crew (SL-LOM, SL-LOV, SL-LOC) probabilities are computed to be of 0.975%, 0.12%, and 0.079%. Finally, from the vehicle’s constraints on the base, the feasibility of the project has been reflected upon. It is deemed that such a concept is of high interest only when the base is already operational, due to the launch and maintenance infrastructure that it requires, as well as the power it requires from the Martian base.
Numerical Investigation of a Radially Cooled Turbine Guide Vane Using Air and Steam as a Cooling Medium
Authors: Norheim Sondre , Amzin Shokri
Published: May 2021

Gas turbine performance is closely linked to the turbine inlet temperature, which is limited by the turbine guide vanes ability to withstand the massive thermal loads. Thus, steam cooling has been introduced as an advanced cooling technology to improve the efficiency of modern high-temperature gas turbines. This study compares the cooling performance of compressed air and steam in the renowned radially cooled NASA C3X turbine guide vane, using a numerical model. The conjugate heat transfer (CHT) model is based on the RANS-method, where the shear stress transport (SST) k−ω model is selected to predict the effects of turbulence. The numerical model is validated against experimental pressure and temperature distributions at the external surface of the vane. The results are in good agreement with the experimental data, with an average error of 1.39% and 3.78%, respectively. By comparing the two coolants, steam is confirmed as the superior cooling medium. The disparity between the coolants increases along the axial direction of the vane, and the total volume average temperature difference is 30 K. Further investigations are recommended to deal with the local hot-spots located near the leading- and trailing edge of the vane.
Dynamic Modeling and Chaos Control of Informatization Development in Manufacturing Enterprises
Authors: Niu Peng , Zhu Jianhua , Sun Yanming
Published: May 2021

To explore the cooperative evolutionary mechanism among top management support, employees’ technical ability, and informatization performance in the process of the “integration of informatization and industrialization (IOII)” in manufacturing enterprises, this study established a three-dimensional dynamic model of informatization development, obtained the model parameters by the expert scoring method of case companies, and analyzed the time series of the dynamic model. After adjusting those parameters of the evolutionary process that do not meet the expectations of the enterprise, combined with management practice, the dynamic system is finally stable at the expected value. For a special state in the evolutionary process, the maximum Lyapunov exponent is used to identify the chaotic characteristics of the system, and a linear controller is designed to manage and control the chaotic system so that it evolves toward the expected value. The results of the case analysis verify the rationality of the model and the effectiveness of the control method, reveal the internal evolutionary mechanism of the informatization development of manufacturing enterprises, and explain the influence of chaos on enterprise management so as to help managers to use and control chaos.

Authors: Glover LáShauntá M. , Cené Crystal W. , Reiner Alexander , Gebreab Samson , Williams David R. , North Kari E. , Sims Mario
Published: May 2021

Background: Psychosocial stressors, such as perceived discrimination and depressive symptoms, may shorten telomeres and exacerbate aging-related illnesses. Methods: Participants from the Jackson Heart Study at visit 1 (2000–2004) with LTL data and Center for Epidemiological Studies-Depression (CES-D) scores (n = 580 men, n = 910 women) were utilized. The dimensions of discrimination scores (everyday, lifetime, burden of lifetime, and stress from lifetime discrimination) were standardized and categorized as low, moderate, and high. Coping responses to everyday and lifetime discrimination were categorized as passive and active coping. Multivariable linear regression analyses were performed to estimate the mean difference (standard errors-SEs) in LTL by dimensions of discrimination and coping responses stratified by CES-D scores < 16 (low) and ≥ 16 (high) and sex. Covariates were age, education, waist circumference, smoking and CVD status. Results: Neither everyday nor lifetime discrimination was associated with mean differences in LTL for men or women by levels of depressive symptoms. Burden of lifetime discrimination was marginally associated with LTL among women who reported low depressive symptoms after full adjustment (b = 0.11, SE = 0.06, p = 0.08). Passive coping with lifetime discrimination was associated with longer LTL among men who reported low depressive symptoms after full adjustment (b = 0.18, SE = 0.09, p < 0.05); and active coping with lifetime discrimination was associated with longer LTL among men who reported high depressive symptoms after full adjustment (b = 1.18, SE = 0.35, p < 0.05). Conclusions: The intersection of perceived discrimination and depressive symptomatology may be related to LTL, and the effects may vary by sex.
Design and Automated Optimization of an Internal Turret Mooring System in the Frequency and Time Domain
Authors: Park Hongrae , Jung Sungjun
Published: May 2021

A cost-effective mooring system design has been emphasized for traditional offshore industry applications and in the design of floating offshore wind turbines. The industry consensus regarding mooring system design is mainly inhibited by previous project experience. The design of the mooring system also requires a significant number of design cycles. To take aim at these challenges, this paper studies the application of an optimization algorithm to the Floating Production Storage and Offloading (FPSO) mooring system design with an internal turret system at deep-water locations. The goal is to minimize mooring system costs by satisfying constraints, and an objective function is defined as the minimum weight of the mooring system. Anchor loads, a floating body offset and mooring line tensions are defined as constraints. In the process of optimization, the mooring system is analyzed in terms of the frequency domain and time domain, and global and local optimization algorithms are also deployed towards reaching the optimum solution. Three cases are studied with the same initial conditions. The global and local optimization algorithms successfully find a feasible mooring system by reducing the mooring system cost by up to 52%.
Russian University Teachers’ Perceptions of Scientometrics
Authors: Grinëv Andrei V. , Bylieva Daria S. , Lobatyuk Victoria V.
Published: May 2021

This article is devoted to the attitude of Russian university teachers toward scientometrics and its indicators, which have been imposed on them by university administrations and the state since 2012. In addition to substantiating the problem’s urgency, the article contains a brief critical outline of the main scientometric parameters and their application in practice in Russia. To evaluate this, 283 people from leading universities in Russia (included in Program 5-100) were questioned. As the study showed, faculties of Russian universities understand the specifics of scientometrics, relate to it relatively positively, and over the past years have been able to adapt to the new requirements of the administration regarding implementing scientometric tasks and standards. The higher the position and scholarly qualification of a respondent, the more complete the knowledge about scientometrics. Scholars in the humanities know and relate comparatively better to scientometrics than representatives of technical and general scientific specialties.
The Influence of Political Ideology on Fake News Belief: The Portuguese Case
Authors: Baptista João Pedro , Correia Elisete , Gradim Anabela , Piñeiro-Naval Valeriano
Published: May 2021

The relationship between a subject’s ideological persuasion with the belief and spread of fake news is the object of our study. Departing from a left- vs. right-wing framework, a questionnaire sought to position subjects on this political-ideological spectrum and demanded them to evaluate five pro-left and pro-right fake and real news, totaling 20 informational products. The results show the belief and dissemination of (fake) news are related to the political ideology of the participants, with right-wing subjects exhibiting a greater tendency to accept fake news, regardless of whether it is pro-left or pro-right fake news. These findings contradict the confirmation bias and may suggest that a greater influence of factors such as age, the level of digital news literacy and psychological aspects in the judgment of fake news are at play. Older and less educated respondents indicated they believed and would disseminate fake news at greater rates. Regardless of the ideology they favor, the Portuguese attributed higher credibility to the sample’s real news, a fact that can be meaningful regarding the fight against disinformation in Portugal and elsewhere.

Published: May 2021

Small intestinal malignant tumor accounts for about 3% of all malignant tumors in the gastrointestinal tract, among which 13% are leiomyosarcoma (LMS). In addition, epithelioid LMS is of very rare occurrence. As small intestinal malignant tumors are initially asymptomatic and nonspecific, diagnosis is often delayed, and this can lead to large tumor at the time of detection and lead to intussusception. We observed ileocolonic intussusception in an 80-year-old male patient who was admitted to the hospital with a complaint of abdominal pain and palpable mass on right lower quadrant. The laparoscopic ileocecectomy was performed by the emergency operation because of obstruction. The pathologic examination revealed that the epithelioid LMS developed in the terminal ileum was the leading point of intussusception. To the best of our knowledge, laparoscopic surgery for ileocolonic intussusception with epithelioid LMS has not yet been reported.

The aim of the study is to describe the national accreditation preparation experience in higher education through the sample of a Faculty of Theology affiliated to a state university. The case study, one of the qualitative research designs, was used in the research. A total of three people experiencing the accreditation process in a state university were determined as the working group. In the research, the participants stated that the accreditation studies have beneficial effects for the institutions and education. They also emphasised that they had difficulties in obtaining the documents during the accreditation preparation phase and that the uncertainty brought about by the new process was challenging. It was pointed out that the accreditation studies would keep the institutions dynamic and carry the quality to advanced levels.
An Analysis of the English Textbooks in Turkish Primary Schools with Regard to the Processability Theory
Authors: Atar Cihat
Published: May 2021

The Processability Theory suggests that teacha bility and learn ability of a language is constrained by what learners are ready to acquire. This means that what is presented to the learners should be in line with their level and readiness. Textbooks are one of the fundamental resources of language learning and teaching, and in this sense, analyzing them is very significant for ensuring that they are appropriate for the target learner group. Accordingly, this study aims to find out whether the stages of different morphosyntactic structuresin 5 English textbooks are sequenced according to the developmental stages offered bythe Processability Theory and whether these 5 textbooks complement each other from the 2nd grade to 4th grade. The 5 English textbooks that are currently being used in public schools in Turkey at primary school level were selected. Textbook Analysis as a part of Document Analysis was undertaken, and the morphosyntactic structures provided in the units of these textbooks were analyzed. The findings suggest that the textbooks follow the stages suggested by the Processability Theory in general; however, there are some incompatibilities as well. The sequential development from the 2nd grade to the 4th grade is in a complementary fashion in that they tend to focus on later stages of morphological development as grade increases except for Primary School Just Fun English 3 (Tıraş, 2018) which was found to present a few morphosyntactic structures that are slightly from higher stages for the expected developmental stage while most of the structures of this textbook conforms to the developmental stages of the Processability Theory as well.

Published: May 2021

Agricultural systems are evolving globally. Farmers and agri-entrepreneurs are demanding trustworthy and efficient extension and advisory services that they can rely on to improve their farming systems and associated enterprises. In this context, extension professionals are expected to be versatile and be competent in their services. Competency refers to having required knowledge, skills and abilities in both process skills and technical subject matters to effectively deliver assigned services. Competency needs are context specific and dynamic. Thus, it is imperative to periodically examine what competencies extension professionals possess and how they value them. This cross-sectional study sought to examine the perceived importance of key competencies among agricultural extension professionals in Nepal. Extension professionals in Nepal’s public agricultural and livestock development offices and agriculture-based non-governmental organizations comprised the study population. Survey data were collected from August to September 2015 through self-, group-administered, and web-based questionnaire. The respondents rated eight core competencies as important or very important. Their perceptions of the importance of these core competencies significantly differed across their current positions, level of education, age, and experience in extension services but not across their educational institutions, employers, and gender. There is a need to develop extension education curricula integrating these core competencies and providing education and training on these core competencies to extension professionals.

Diante da dificuldade de se trabalhar alguns assuntos geográficos, o professor é estimulado a buscar recursos didáticos que possibilitem o aluno visualizar determinado conteúdo na prática, propiciando uma maior e melhor aprendizagem.  Embora a maquete seja um destes recursos, poucos trabalhos apresentam detalhes para sua construção e de que forma ela pode ser melhor utilizada no ensino. Este trabalho objetivou auxiliar os professores de Geografia e áreas correlatas apresentando, detalhadamente, a construção de uma maquete didática representativa da bacia hidrográfica do Arroio dos Kaster, localizada no município de Pelotas-RS, e como ela pode ser utilizada na abordagem de conteúdos geográficos para os diferentes níveis de ensino. Espera-se que este material auxilie os professores na construção de maquetes didáticas e forneça subsídios de como elas podem ser melhor utilizadas no ensino de Geografia e áreas correlatas.

Peperomia pellucida attracts a lot of interest due to its bioactivity and has been used in various folk medicine. In this report, n-hexane, dichloromethane, and ethyl acetate fraction of Peperomia pellucida extract were examined for its cytotoxic activity against Artemia salina larvae using the BSLT method. The ethyl acetate fraction showed higher cytotoxic activity than n-hexane and dichloromethane. The LC50 of ethyl acetate, n-hexane, and dichloromethane fractions was 39.665, 278.920, and 60.808 ppm, respectively. Mayer and Dragendorff tests give a positive result to the alkaloid constituent in ethyl acetate fraction. The alkaloids in Peperomia pellucida were extracted using ethyl acetate and further separated using chromatography techniques. Two alkaloid components were identified in ethyl acetate fraction from Peperomia pellucida as Piperine and Nigramide N by using LC-MS/MS.
Conflictos laborales y clase trabajadora platense en torno a los años '60
Authors:   , Raimundo Marcelo Fabián
Published: May 2021

Esta tesis se propone realizar una contribución a los estudios sobre la historia de la clase trabajadora argentina, a partir del análisis de la conflictividad laboral y la dinámica sindical en la zona platense (La Plata, Berisso y Ensenada) durante los años '60. En este marco, el recurso a una historia local y regional tiene como objeto utilizar la riqueza de dichas dimensiones de análisis para construir una imagen más profunda y compleja de los procesos de lucha y organización de la clase obrera durante la segunda parte del siglo XX. Para llevar a cabo este trabajo, el foco de observación estará puesto en episodios que remiten a diversas acciones, prácticas y modos de organización de la clase trabajadora platense, algunas más frecuentes y otras más excepcionales. El modo de aproximación estará orientado por la búsqueda de la coincidencia, el contrapunto o la novedad. Esto posibilitará un estudio comparado con hechos en que se basan las pocas pero conocidas obras de la historiografía laboral nacional (que muchas veces vienen a simbolizar ‘lo general’ de un periodo), y con trabajos sobre casos locales (que caen atrapados en una tensión entre su singularidad y su relación con una época). En lo que remite a las organizaciones de la clase trabajadora, se incluirán distintas escalas de análisis, según lo permita el material empírico disponible: lo intersindical, lo sindical, comisiones internas, cuerpos de delegados, militantes y activistas fabriles, y las bases trabajadoras. En lo que refiere al plano de la lucha, los conflictos laborales serán recorridos en el cruce de la estructura económico-social y la subjetividad político-sindical locales, con los procesos más generales del país en aquellos años.

Pelatihan Pengolahan Limbah Kulit Buah Nanas Menjadi Pupuk Organik Cair di Distrik Bokondini

Published: May 2021

Besarnya potensi pertanian Nanas di Distrik Bokondini belum dimanfaatkan secara maksimal oleh petani. Kebanyakan pemanfaatannya dilakukan dengan cara menjual secara mentah tanpa diolah oleh mereka. Telah ada pengolahan nanas menjadi selai nanas tetapi belum digarap secara sungguh- sungguh, dengan penjualan masih secara lokal. Hasil pengolahan selai nanas ini diketahui menghasilkan limbah kulit nanas yang bernilai sebagai limbah atau sebagai pakan ternak. Hal ini disebabkan karena minimnya pengetahuan yang dimiliki petani terkait sistem pertanian organik yang sebenarnya. Untuk itu, pelaksanaan kegiatan pengabdian masyarakat ini perlu dilakukan sebagi salah satu upaya diversifikasi pengolahan produk olahan buah nanas sebagai pupuk organik cair yang bermanfaat bagi produktivitas tanah maupun tanaman. Hasil kegiatan pengabdian ini memberikan dampak positif dan pembelajaran yang baik bagi masyarakat dalam mengembangkan pengetahuan terkait pemanfaatan kulit buah nanas yang selama ini hanya dibuang atau dijadikan pakan ternak babi.
