Applying Gamification to Enhance the Universal Design for Learning Framework
Authors: Majdoub Mourad
Published: February 2022

In today's classrooms, several students are confronted with situations where access and meaningful learning opportunities are a daily ordeal. While the Universal Design for Learning (UDL) framework can be used to proactively design and develop lessons that address the individual needs of a range of learners, more research into the mechanisms that would facilitate the implementation of the UDL principles is needed. Gamification and game-based learning have risen as a promising tool to provide accessibility to a wide range of learners through game features. Drawing on the UDL principles, this study reviews some key gamified design features that would allow full access to the general curriculum for the broad range of learners found in today's diverse classrooms. Teachers, educators, and learning material developers can take away some practical ideas that can help inclusive lesson plans involving game-based learning.
Making and Active Learning in Higher Education
Authors: Bertrand Marja , Barek Hiba , Namukasa Immaculate Kizito , Campigotto Rachelle
Published: February 2022

In this study, the authors researched, designed, and implemented maker education opportunities into teacher candidate training, specifically in elementary mathematics and science methods courses. To investigate the impacts of active learning and maker education models in the teacher education program, the researchers observed, interacted with, and asked teacher candidates (1) which instructional design practices were helpful, (2) what they learned (i.e., knowledge gained, effective pedagogies, and teaching methods) and (3) what were the impacts of these learning opportunities in the context of learning to teach mathematics and other STEM subjects? The Maker Ed workshops involved creating opportunities for teacher candidates to gain experience of how to make, exploring ways to incorporate making in a variety of contexts and then extending this learning to their own pedagogy. To better prepare students for the workforce and everyday living, life skills, transferable skills, and workforce competencies need to be taught through student-centered and activating instructional practices.

Voices of Educators
Authors: Hickman Desiree , Glass Wykeshia , West Brandy
Published: February 2022

Teaching and learning practices in higher education are undergoing a number of changes that have significant implications for the nature of students' learning experiences in classroom settings. In the last several decades, various modes of active learning have been introduced in efforts to enhance student engagement and deepen student pedagogical knowledge. Active learning is considered to be the connection of what knowledge we already possess to the knowledge we desire to acquire. The ultimate goal in active learning is to balance personal motivation for self-fulfillment with group capacities so that we are able to make high impact contributions to the world. This chapter examines instructors' understanding of active learning strategies and the benefits of implementing these strategies in classroom settings. The information presented focuses on forms, methods, and models of the active learning process and is meant to raise interest and awareness on the importance of students' active participation in their learning process.
Active Learning Compared With Lecture-Based Pedagogies in Gender and Socio-Cultural Context-Specific Major and Non-Major Biology Classes
Authors: Hewapathirana Gertrude Iranganie , Almasri Firas
Published: February 2022

This chapter provides new insights on the experimental research that hypothesized whether the gender group composition in active learning (AL) versus traditional lecture (TL) classrooms of undergraduate biology majors and non-majors correlate with students' achievements and attitudes. The research found that AL improves males' achievements and attitudes while females perform lower in their tests and exams in mixed-gender groups. In single-gender groups, female achievements were higher in both TL and AL classes. The authors argue that students' gender and gender group composition and associated socio-cultural beliefs have been the most influential factors in students' achievements and framing attitudes towards science learning. The findings suggest that underlying socio-cultural, social identities, and associated beliefs supersede the effectiveness of pedagogical approaches. Thus, there is a need for developing gender-specific and context-specific teaching pedagogies, and instructors carefully select gender grouping in teaching undergraduate science subjects.

An Overview of Welding Methods for Advanced Materials
Authors: Rayapandi Thiraviam , Suresh P.
Published: February 2022

Recent developments in the engineering industry require joining of like and unlike materials with different properties such as melting point, coefficient of thermal conductivity, solubility, difference in electrochemistry, etc. as part of machines, tools, and more specific applications. Materials including those similar and dissimilar in nature are successfully joined by fusion and solid-state welding processes. In accordance with ASME Sec IX and AWS D1.1 codes and API 1104 standard, welding procedures specifications (WPS) through procedure qualifications (PQR) are required prior to commencing any fabrication work pertaining to pressure vessels, piping and pipeline, storage tanks, offshore platform structural parts, and so on. A specific welding process must be chosen based on the design of the component, the material, thickness, production, availability of equipment, people, and other factors. Weldment testing, including destructive and non-destructive examinations, are crucial during procedure qualification, welder qualification, and the production welding process.
An Exploration of the User Experience of Mobile Mental Health Apps Using the Critical Incident Technique
Authors: Mihalo Jakub , Halamova Julia
Published: February 2022

Although mobile applications are increasingly being used as a viable option for improving individuals' psychological health, there is a lack of research in this area. This qualitative study analysed user experiences of mobile mental health applications (MHapps) among the English-speaking general population of 462 participants using the critical incident technique. The authors employed an online questionnaire method to gather responses. The analysis yielded three main domains: type of MHapp, impact on life, and recommendations. Participants use MHapps to calm down, do tasks, track, and connect with others or chat-bots for specific disorders. This study outlines the specific cognitive, emotional, and behavioural changes in participants' lives resulting from the mobile interventions. The results confirm and broaden the existing theoretical knowledge and recommendations for MHapps development in terms of usability, accessibility, and content. Further confirmatory studies are needed to validate the results for specialized MHapps using different analysis and data gathering techniques.
Research on the Status Quo and Influencing Factors of Gender Differences in the Executive Salaries of Listed Companies
Authors: Zhongwen Liu , Xiaoshuang Wang , Shukun Wang
Published: February 2022

Gender pay difference has always been a concern of scholars. Especially in recent years, experts have gradually shifted their research horizons to gender pay difference of executive compensation. This paper takes executive compensation of listed companies as the research object, uses fixed effect model to study gender pay difference of executive compensation of listed companies from 2016 to 2020, and finds that the gender gap of executive compensation of listed companies shows a trend of decreasing first and then increasing, and the proportion of female executives has an insignificant reverse effect. Private enterprises have a significant reverse effect on the gender gap of executive compensation. That is, there is a gender difference in executive compensation of listed companies, and the factor affecting the gender gap is the nature of the company, while the proportion of female executives are not regarded as the influencing factor.

Authors: Wang Valerie L. , Wang Yong , Gault Jack , Baeza Miguel A.
Published: February 2022

The objective of this study is to compare Hispanic and Caucasian Generation Y women's social dating ad humor styles using theoretical paradigms related to cultural norms, gender role, and education. Content analysis is performed on 400 dating ads collected in an interactive digital dating app. The results show that young Hispanic and Caucasian women share the same frequency and some similar patterns in the use of humor in social dating. In spite of the non-significant results on cultural differences, education significantly influences dating ad humor styles of young women, as those with less education tend to use negative ad humor styles more often, and those with more education use a greater amount of positive humor. The findings offer insights into how humor is used by diverse consumers in social media and C2C advertising.

There was a significant relationship between attitude and practice, with a correlation coefficient of r = 296, n = 120, and p = 0.001.Conclusion: The results of this study show that nurses’ practices were associated with their attitudes regarding maternal nutrition, meaning their attitudes regarding maternal knowledge transcends their related knowledge.Contribution: The study contributes to the body of literature about the knowledge, attitudes and practices of nurses related to maternal nutrition. It has the potential to lead to the betterment of nursing care, which in turn results in improved pregnancy outcomes in women.
The Inedita Homily In transfigurationem Domini (BHGn 1980a): A compilation using Proclus of Constantinople
Authors: Gârbacea Radu
Published: February 2022

In his inventory of the manuscript tradition of the homilies on the Transfiguration, Maurice Sachot stated that folios 46r–55r of the codex Parisinus graecus 1611 contain the homily In transfigurationem Domini (BHGn 1980a). He also stated that this text is unedited and that it is most probably a recension of the homily In transfigurationem Domini (CPG 5807; BHG 1980) attributed to Proclus of Constantinople. To date, however, this homily has remained unpublished and unstudied. After a brief presentation of the codex Parisinus graecus 1611, this article brings to light a surprise that emerges from examining folios 46r–55r of the Parisian manuscript.Contribution: The article proves that the homily In transfigurationem Domini (BHGn 1980a) is not a recension of the homily on the Transfiguration (CPG 5807; BHG 1980), but a compilation for which the beginning of the homily on the Transfiguration attributed to Proclus of Constantinople was used.
Systemic support for learners with developmental language disorders in Zimbabwe and South Africa
Authors: Ndou Nettie N. , Omidire Margaret F.
Published: February 2022

Background: Teachers play a significant role as early identifiers of learners with developmental language disorder (DLD). They provide important information to other professionals for further specialist support of such learners. Professionals, such as educational psychologists, speech–language therapists (SLTs) and learning support therapists are involved in assisting learners with DLD; hence, inter-professional collaboration (IPC) amongst these professionals is of paramount importance in meeting the needs of learners.Objectives: This study aimed to examine systemic support strategies available to learners with DLD.Method: This was a multiple case study of Zimbabwe and South Africa. Purposive sampling was used to select participants. The study consisted of 56 participants: 5 teachers, 2 SLTs, a learning support therapist, an educational psychologist and 47 learners. A qualitative research approach was employed and data were collected using interviews, focus group discussions and classroom observations. The data were analysed thematically and categorised.Results: Support strategies employed by teachers include remedial lessons and promoting a culture of reading for leisure to enhance learners’ vocabulary and narrative skills. The SLTs and the learning support therapist use speech–language programmes and assistive technologies. Limited IPC and the absence of SLTs in District Based Support Teams were some of the challenges identified. The results also indicate that SLTs receive referrals mostly from primary schools compared with secondary schools.Conclusion: Raising awareness of DLD in schools and communities is deemed essential. Inter-professional collaboration is recommended to support learners with DLD as it increases the exchange of ideas and mutual acknowledgement of expertise amongst professionals.

Childhood theology and implications for pedagogy
Authors: Chiroma Jane A. , Chiroma Nathan H.
Published: February 2022

This article argues for a childhood theology informed by systematic theology, which enabled the researcher to mould the concepts of childhood theology to understand in order to use it. Child theology has been a neglected study in most African scholarship. Systematic theology guided the analysis of data as objectively as possible and contributed to the development of a childhood theology model that best accounts for all the data, showing that how childhood theology can be constructed in the African setting. The philosophy of Christian education aided the analysis of childhood theology and to assess the pedagogical relevance towards maximising a child’s potential in learning. Considerations of African theological perspectives, western perspectives and biblical evidence for childhood theology are explored to configure its significance to African childhood theology and the implications for pedagogical practices that are holistic, God-centred and transformative.
Correlation between Intraoperative Serum Lactate and New-Onset Postoperative Neurodeficits in Patients Undergoing Elective Craniotomies
Authors: Fazili Rashid Javad , Naqash Iqra Nazir , Ali Zulfiqar , Bhat Abdul Rashid , Mir Altaf Hussain , Mir Shahid Ahmad
Published: February 2022

Background:

Elevated lactate levels in neurosurgical patients are seen in brain tumors, traumatic brain-injury, brain infarction, and subarachnoid hemorrhage. Hyperlactatemia during craniotomy may be caused by hypotension due to multiple factors. Recently, intraoperative hyperlactatemia has been associated with fresh-onset neurodeficits.

Aims:

We studied the prevalence of hyperlactatemia in patients undergoing craniotomy and relationship between intraoperative hyperlactatemia and development of new postoperative neurodeficit.

Study Design:

Eighty-six patients, American Society of Anesthesiologists Classes I,II and III, undergoing elective craniotomy for neurosurgical indications were included in this prospective, observational study in a tertiary care center.

Materials and Methods:

Baseline, intraoperative, and postoperative (upto 12 h) lactate levels were noted. Neurological examination to detect new-onset neurodeficits was done at intervals up to 72 h postoperatively. Lactate levels were compared between patients who developed neurodeficits and those who did not develop neurodeficits postoperatively.

Statistical Analysis:

Statistical analysis of the correlation between intraoperative hyperlactatemia and fresh postoperative neurodeficit was done using the Chi-square test.

Results:

The prevalence of intraoperative hyperlactatemia was found to be 52.3% and that of fresh-onset postoperative neurodeficits was 31.4%. The relationship between the two was statistically insignificant (P > 0.05).

Conclusion:

The intraoperative hyperlactatemia is not correlated with the development of fresh-onset postoperative neurodeficit.

Implications:

There may be no relationship between the intraoperative lactate levels and fresh-onset postoperative neurodeficits. Multifactorial reasons may be responsible for increased lactate levels which need to be identified by further research.
Pediatric Deep Sedation for Ophthalmology Procedures in an Outpatient Setting, Risk Evaluation
Authors: Evans Michael Russell , Thompson Tonya , Hsu Christine , Spray Beverly , Edwards Lauren R. , Grigorian Adriana , Dalabih Abdallah
Published: February 2022

Background:

Pediatric deep sedation (PDS) performed by a dedicated pediatric sedation service has been found to be safe, convenient, and efficient for minor procedures. Major complications such as cardiopulmonary resuscitation, intubation, and death are rare. However, minor complications such as desaturation, apnea, suctioning, or laryngospasm can occur infrequently. To date, little data exist evaluating PDS use for minor ophthalmology procedures.

Aims:

The aim of this study was to evaluate the incidence of complications for subjects receiving PDS for minor ophthalmology procedures.

Setting:

Pediatric children's hospital sedation service.

Materials and Methods:

This was a review of a prospectively collected database between 2018 and 2020. A hundred and thirty-four subjects aged 0–18 years, who underwent PDS for minor ophthalmology procedures, were compared to 1119 subjects who received PDS for other procedures (e.g., lumbar puncture, bone marrow aspirate/biopsy, and Botox).

Statistical Analysis:

SAS software, version 9.4, was used to determine variables associated with deep sedation that were predictive of complications. A multiple logistic regression procedure was conducted. Statistical significance was set at the 0.05 level.

Results:

Subjects receiving PDS for ophthalmology procedures had a higher rate of minor complications than the control group (n = 18, 13.4%, vs. n = 58, 5.7%; P < 0001). No major complications occurred in any of the studied subjects. The ophthalmology group had a higher rate of bag-mask ventilation, airway positioning, and suctioning.

Conclusions:

Ophthalmology procedures using PDS have a greater occurrence of minor complications compared to other painful procedures. No major complications were noted in either group, providing evidence that PDS can be performed safely for ophthalmology procedures using the sedation team model.
Recovery Profile of Sugammadex versus Neostigmine in Pediatric Patients Undergoing Cardiac Catheterization
Authors: Saber Hosam I. El Said , Mousa Sherif A. , AbouRezk Ahmed Refaat , Zaglool A
Published: February 2022

Background:

Sugammadex is a selective reversal agent which has the ability to reverse deep neuromuscular blockade. However, there are still controversial results as regard sugammadex effects on the quality of recovery. We hypothesized that Sugammadex may have better recovery profile compared to neostigmine in pediatric patients with congenital heart diseases undergoing cardiac catheterization.

Patients and Methods:

This prospective randomized double-blind study included 50 pediatric patients aged <2 years who were divided into two groups according to the reversal agent used; Group S (Sugammadex) and Group N (Neostigmine). Both groups received the same anesthetic technique during cardiac catheterization, and basic hemodynamic monitoring was ensured in both groups. After the procedure, reversal was done using 4 mg.kg[FIGURE DASH]1 sugammadex or 0.04 mg. kg[FIGURE DASH]1 neostigmine plus 0.02 mg. kg[FIGURE DASH]1 atropine according to the group allocation. Recovery time and side effects were recorded.

Results:

The two groups showed comparable findings regarding demographics. Nonetheless, the total time of anesthesia had mean values of 91.06 and 101.25 min in the two groups, respectively (P = 0.003), while recovery time had mean values of 1.61 and 9.23 min in the same groups, respectively (P < 0.001). Hemodynamic profile (heart rate and mean arterial pressure) was better after reversal with sugammadex. Blood sugar levels and side effects showed no significant difference between both groups.

Conclusion:

Sugammadex can be a more rapid and effective alternative to neostigmine for reversal of rocuronium-induced neuromuscular blockade in pediatric patients undergoing cardiac catheterization.

Authors: Tian Zhen , Li Yong-Gang , Li Guang-Zheng , Huang Zhi-Hao , Dai Wen-Hao , Wei Xue-Dong , Zhang Wei-Jie , Fu Zhen-Yu , Huang Yu-Hua
Published: February 2022

Clinical staging, Gleason score, and prostate-specific antigen (PSA) have been accepted as factors for evaluating the prognosis of prostate cancer (PCa). With the in-depth study of iron metabolism and the development of multiparametric magnetic resonance imaging technology, we used q-Dixon magnetic resonance imaging (MRI) to measure the iron content of the PCa patients’ lesions, and used enzyme-linked immunosorbent assay (ELISA) to measure the iron metabolism indicators in the patients’ serum samples, combined with the patients’ postoperative clinical data for analysis. We found that the serum indexes were correlated with the T2 star values, International Society of Urological Pathology (ISUP) grade, and pathological classification in PCa patients (all P < 0.001) but not in benign prostatic hyperplasia (BPH) patients (all P > 0.05). The utilization of q-Dixon-based MRI and serum indexes allows the noninvasive measurement of iron content in prostate lesions and the assessment of differential iron metabolism between PCa and BPH, which may be helpful for evaluating the prognosis of PCa.

Authors: Huang Wei , Wang Yina , Yang Fanchun , Luo Ning , Ai Guihai , Wu Yuliang , Cheng Zhongping
Published: February 2022

Objectives:

The aim of this study was to compare the lymphovascular space invasion between laparoscopic radical hysterectomy (LRH) and abdominal radical hysterectomy (ARH).

Materials and Methods:

One retrospective study was conducted with 391 patients treated with 242 patients underwent ARH and 149 patients underwent LRH between May 2010 and August 2019. We collected clinicopathological and perioperative outcome from medical records. We adopt Student's t-test and Chi-square test was used to compare continuous and categorical variables between LRH and ARH.

Results:

Our research found that there was no difference in tumor size, histology, pathology grades, positive lymph nodes, and postoperative complications between LRH and ARH (P > 0.05). The estimated blooding loss (EBL) and length of postoperative hospital stay were less for LRH than ARH (248.12 ml vs. 412.56 ml, P < 0.05, and 10.48 days vs. 15.16 days, P < 0.05). The mean operative time was longer for LRH than ARH (227.51 min vs. 215.62 min, P < 0.05). Significant difference was found in intraoperative complications (P < 0.05). However, LVSI was higher for LRH than ARH (36.8% vs. 19.8%, P < 0.05). We discovered that the LVSI was related with International Federation of Obstetrics and Gynecology stage and tumor size.

Conclusion:

Compared to ARH, the LRH would be advantageous for early cervical cancer in terms of EBL, length of postoperative hospital stay, and intraoperative complications. The ARH was superior to LRH in operative time. In addition to, LRH was more likely to lead to LVSI. Furthermore, when tumor size or stage was increasing, LRH was easily to generate LVSI. But, we cannot confirm recurrence rate is related to LVSI.
Spectrum of Ectopic Pregnancies at a Tertiary Care Center of Northern India
Authors: Verma Manju Lata , Singh Uma , Solanki Vandana , Sachan Rekha , Sankhwar Pushp Lata
Published: February 2022

Objectives:

Diagnosis of ectopic pregnancy (EP) needs high index of clinical suspicion. If EP is timely diagnosed and timely intervened, i.e., before rupture, it may cause reduction of serious morbidity and mortality. We aimed to analyze the profile of patients of ectopic pregnancies and their outcome.

Materials and Methods:

The sample for this retrospective cross-sectional study was derived from the database from January 2017 to December 2020. Data from outdoor patient registers, case record files, discharge summaries and hospital admission/discharge registers were screened. Parameters age, parity, risk factors, clinical presentation, per-operative findings, and maternal outcome in terms of morbidity and mortality were assessed.

Results:

Totally 27,525 deliveries occurred during the study period of 3 years, of which 640 were ectopic pregnancies, i.e., 2.3%. Out of 640, 415 (64.8%) were acute ruptured ectopic pregnancies, 62 (9.6%) were chronic ruptured pregnancies, and 163 (25.4%) patients were unruptured ectopic pregnancies. The mean age was 28.67 years (range: 29.5–27.8). The most common site of rupture was ampullary (54%, 225/415). 14.8% (95/640) of cases were in hemorrhagic shock out of total ectopic patients, and in ruptured group, they comprised 22.8% (95/415). Success for medical management with single-dose methotrexate in our study was 90.2% (147/163).

Conclusion:

Pelvic inflammatory disease and history of induced abortion were found to be the most important etiological factor in ectopic pregnancies. Comprehensive clinical examination is 100% sensitive in diagnosis of EP. In ultrasound, the presence of adnexal mass is the most common finding which is additive to clinical findings and not substitute. Although multiple management options are available, best outcome is attained if management of EP is done at earliest without any delay.

Published: February 2022

Background and Objectives:

Severe respiratory syndrome caused by coronavirus 2 (SARS COVID-19) was declared a pandemic by the World Health Organization (WHO) on March 12, 2020. In India, the central government declared lockdown on March 25, 2020. We report the trends in admissions for acute coronary syndromes (ACS) at cardiac care units (CCUs) during lockdown and impact on reperfusion strategies adopted during this time period in comparison with the previous year.

Materials and Methods:

We conducted a multicenter retrospective observational survey on admissions for ACS at CCUs of Ernakulam district in Kerala from January to May 15, 2020. Records were analyzed for admissions during equivalent period of 2019. Trends in admissions during lockdown phases were analyzed separately.

Results:

We observed an 18.2% reduction in admissions for ACS during lockdown. A significant reduction in number of patients presenting with ST elevation myocardial infarction (STEMI) (186 vs. 169 and 130 vs. 82) was observed when compared to 2019 (P = 0.0047). Decrease in number of primary angioplasties was noted during lockdown phase (302 vs. 244. P = 0.049). There was an increase in adoption of thrombolysis as reperfusion modality at tertiary care centers during lockdown period (27.1% vs. 40.8%). We did not observe an increase in number of patients who presented late during this phase and there was no heterogenicity in admission pattern according to hospital location.

Conclusion:

Study confirms a significant reduction in admissions for ACS during lockdown period and change in reperfusion strategies adopted during lockdown.

Published: February 2022

Lipomatous atrial septal hypertrophy (LASH) is a benign lesion characterized by massive accumulation of fat in the interatrial septum. Multimodality imaging, with echocardiography being the first technique, complemented by multislice computed tomography or magnetic resonance imaging help to make accurate diagnosis. Here, we report a case with a LASH with epicardial fat extension causing aneurysmal dilatation of left superior pulmonary vein with thrombus formation and pericardial effusion.
Hitchin components for orbifolds
Authors: Alessandrini Daniele , Lee Gye-Seon , Schaffhauser Florent
Published: February 2022

We extend the notion of Hitchin component from surface groups to orbifold groups and prove that this gives new examples of higher Teichmüller spaces. We show that the Hitchin component of an orbifold group is homeomorphic to an open ball and we compute its dimension explicitly. We then give applications to the study of the pressure metric, cyclic Higgs bundles, and the deformation theory of real projective structures on 3-manifolds.

Authors: Tilahun Girma , Pavanasam Natarajan , Getahun Abebe , Teame Tsegay
Published: February 2022

This Bibliography of Aquatic Sciences, Fisheries and Aquaculture is prepared with the intention of providing the opportunity for different users to easily search for references that concentrate on Aquatic Sciences, Fisheries, and Aquaculture   (ASFA).  It is a collection of both grey literatures and scientific articles published in scientific journals. The grey pieces of literature include papers presented in conferences, symposia, and workshops, Ph.D. dissertations and MSc theses of various national and international universities submitted as an academic requirement for graduation. It should be noted that there are many more monographs of these types that could be found mainly in different universities in Ethiopia. The scientific papers published in Journals and included in this bibliography should be checked for reputability. As the bibliography contains grey literatures and published papers it can serve as a source of relevant information and data useful for metaanalysis on key topics/issues of ASFA.  It will also help the scientific community to enhance their teaching, research and extension activities. Moreover, the long list of references included in the bibliography shows the immense contribution of prominent researchers that promoted, not only their carrier but their profession in the aforementioned three specialized fields. Since the Bibliography is a collection of research reports taken from different sources, there may be a lack of consistency while writing the references. For instance, Ethiopian authors include full father name while writing most of the references, however, abbreviated father name is included whenever the original paper does not have full father name. Finally, it should be noted that this bibliography on ASFA is brought out for the first time in Ethiopia, and we are confident that it will be updated in due course through contributions and feedback from researchers in the field.

Knowledge Hoarding at a State University Library in Zimbabwe
Authors: Mutage Moses , Dewah Peterson
Published: February 2022

Despite the need to bridge the knowledge gap introduced by technology, knowledge hoarding by library staff seems to affect service delivery at a state university library in Zimbabwe. The study employed a qualitative research approach in a case study design, informed by the interpretive paradigm. The target population of this study consisted of senior library management personnel and their subordinates. Maximal variation purposive sampling strategy was chosen to sample twenty-six library staff/ individuals that differ on some characteristics. Data were generated using interviews and observations. Key findings revealed that mistrust, unfair treatment, poor interpersonal relations, lack of recognition, and absence of a reward system induce knowledge hoarding and discourage library staff from sharing experiences. Furthermore, the study revealed that while librarians hoard knowledge as a security strategy for indispensability, hoarding knowledge has led to individualism and privatisation of knowledge. The study concluded that withholding of knowledge, for whatever reason, results in negative implications on the performance of new roles and service delivery. The study recommends that library staff should change from knowledge hoarding to sharing their knowledge; that the state library should implement a knowledge sharing policy; that the university library should reward knowledge sharing and recognize knowledge contributions from subordinates.

Work related injuries, damages of properties, diseases and death are increasing. They are caused by working tools, environment or human actions which are used in the production activities. In this regard, there is a need to come out with measures to address the problem, through which workplace hazards can be reduced. The current study therefore assessed the roles of occupational health and safety management system in reducing workplace hazards. Specifically, the study identified the roles of occupational health and safety management guidelines, programmes and administrations in reducing workplace hazards. A questionnaire distributed to 285 respondents was used to collect primary data from big five manufacturing companies in Dar es Salaam. While the respondents were selected both conveniently and purposefully, the manufacturing companies were selected purposefully. The data were analyzed by using Partial Least Square –Structural Equation Modeling (PLS – SEM). Tables were used to describe demographic characteristics of the respondents. The findings of this study indicate that effective use and implementation of OHS guidelines, programmes and administration are crucial in reducing workplace accidents, injuries, damages and work-related diseases. The study recommend that companies have to administer, use and implement appropriate occupational health and safety policies, guidelines and programmes so as to reduce accidents, injuries, damages of properties and work-related diseases.

Loan is a amount that is provided to someone else in exchange for repayment of the loan principle amount plus interest. The different variety of loans is Personal loan, Home loan, Education loan, etc. Here, Decision Tree and Naïve Bayes algorithms are used to predict the loan eligibility of a particular individual. Data mining techniques are used to extract data and predict the loan eligibility. By providing loan, the banks help in the overall flow of the economy of the country. The borrower can avail the loan whenever required and the bank can get back the principle amount with interest based on some pre-defined percentages.

Following the declaration of the state of emergency in Serbia, after the novel COVID-19 outbreak was declared a global pandemic, all the educational institutions in the country were closed, and the different modes of emergency remote teaching (ЕRТ) were introduced. In order to highlight the problems and attitudes of students, in regard to the newly introduced online-based emergency remote teaching model, we conducted a survey with high school students. The research question was how the unplanned switch from the traditional learning setting to online learning affected the learning practice, and what the outcomes of the integration of digital technology in education are. The aim of the study was to determine the best advantages and the biggest disadvantages of the introduced emergency remote teaching model, from the students’ point of view, during the initial phase of the teaching model implementation. The obtained results indicated the best advantages of the applied learning model in the domain of learning time management opportunities, and the biggest disadvantages in relation to the teaching and learning technical support problems and social distance. The results of this study could be used by policymakers and practitioners in order to prepare plans and programs for emergency remote teaching, and also to improve traditional teaching models.

With the appearance of the Sars-Cov2 virus pandemic, all schools in Serbia, as well as in almost all parts of the world, applied a combination of online and direct teaching ‒ hybrid teaching. Flipped classroom is the most famous model of hybrid teaching, which implies “reversal” of the classic way of working in the classroom and at home. Students learn new teaching contents at home, with the help of multimedia contents, and at school the material is determined and applied through active teaching ‒ discussion, research activities, problem solving, experiments, projects, etc. The aim of the research is to examine the attitudes and experiences of teachers working in primary schools on the application and didactic-methodological specifics of the flipped classroom teaching model. The results show that teachers are familiar with the concept of flipped classroom and very successfully determine the key elements related to its didactic and methodological specifics. The largest number of respondents points out the following key elements of flipped class- room: swiching schoolwork for homework, emphasizing the individualization of teaching, problem solving, interactivity in teaching, active participation of students, etc., which are actually the most important features and advantages of this innovative model. Most teachers have a positive attitude towards the flipped classroom model and its application in teaching science during a pandemic. It is assumed that it is worth investing additional efforts in the implementation of this model of work in teaching practice, because a positive attitude of teachers towards a novelty is a necessary, certainly not sufficient, condition for innovating the teaching process. Additional support and training of teachers, as well as a database with examples of good practice for the application of flipped classroom, would certainly contribute to intensifying the application of this model in schools, both in teaching science and other subjects, especially during the pandemic, which contributed to a more frequent use of hybrid teaching.

The analysis of the influence of changes in the parameters of steam superheater separators SHS-1000 of nuclear power plant units with the capacity of 1000 MW on the efficiency and safety of their operation, including the temperature characteristics at the nominal and partial operating modes of power units, has been carried out. Based on the experimental data of the thermal tests of the power unit, the temperature characteristic of the second stage of the SHS-1000 has been constructed in the form of the dependence of the temperature change of the heated steam at the second stage of the SHS on the change in the operating mode of the power unit. To create a correct mathematical model of this dependence, taking into account the limited amount of experimental data and the uncertainty of information about the structure and the probabilistic nature of measurement error during testing, the use of numerical methods of interval analysis has been proposed. Interval analysis has allowed to obtain an interval model that describes the receiver, which contains all possible values of the dependence of temperature change of the heated steam at the second stage of SHS on the unit operating mode (the electrical load). It has been shown that in conditions of limited initial data and uncertainty of information about it, numerical methods of interval analysis allow to create interval models of operational (energy) characteristics technological processes and equipment of NPP units with the maximum possible correspondence to real processes and objects, which is important to ensure high efficiency and safe operation of power units.
Juventude e participação na escola: Disputas e relações no cotidiano escolar
Authors: Martins Francisco André Silva , Dayrell Juarez Tarcísio
Published: February 2022

O presente trabalho tem como objetivo discutir as relações estabelecidas entre os jovens do grêmio estudantil, os professores e a direção de uma escola pública de ensino médio. O intuito do artigo está em perceber as tensões decorrentes da participação do estudante em seu cotidiano escolar, bem como, os reflexos dessa experiência. As questões suscitadas caminham no sentido de perceber que o processo participativo escolar é perpassado por disputas entre sujeitos que defendem interesses, muitas vezes, distintos. O funcionamento da escola, por vezes, contempla o “ser aluno” e tal imagem pode não ser condizente com a participação dos jovens no cotidiano escolar. O processo de atuação dos jovens gremistas provoca uma tensão entre lógicas distintas: a dinâmica dos jovens e a estrutura da escola. Como um espaço socializador, com dinâmica própria, o grêmio e as atividades promovidas pelos jovens gremistas, podem sinalizar um caminho importante para a quebra de estereótipos e para uma atuação diferenciada do estudante em seu processo de formação escolar.
