Implementation of Postmethod Pedagogy as an Alternative to Communicative Language Teaching at the Tertiary Level Education
Authors: Islam Naushin Nazifa
Published: October 2020

Along with the subsequent development in the field of English Language Teaching, the idea of methods has been criticized for not being sensitive to the contextual factors and also for being imperialistic in nature. The linguistic and cultural dimensions of archetypal methods establish the culture and language of the native speakers as the only erudite variety by promoting monoculturalism and monolingualism. Furthermore, even in Bangladesh, it can be seen that CLT has been applied as a method to teach English as a foreign/second language since the mid-nineties, but it has not brought any significant changes. Therefore, to overcome the obstacles and limitations experienced by the application of the prototypical methods, the notion of postmethod pedagogy has been introduced which focuses on the significance of contextualized materials to bring authenticity in English language classrooms, which in turn ensures learners’ motivation and successful intake of the lesson. At the same time, it also emphasizes the importance of teacher and learner autonomy. Hence, this research paper explores the scopes of the implementation of postmethod pedagogy and its effectiveness at the tertiary level English language classrooms in Bangladesh.

The Dream of Clinical Supervision, Critical Perspectives on the State of Supervision, and Our Long-Lived Accountability Nightmare
Authors: Garman Noreen
Published: October 2020

This memoir essay was originally intended to revisit a time when instructional supervision became the ubiquitous practice in a ‘golden age of supervision,’ and to valorize colleagues who contributed their scholarly canons to the field. An introductory narrative describes the goals and hopes of a field that emerged through Morris Cogan’s popular clinical supervision, and other scholars who adopted and altered his principles with dreams of a road to effective school reform. It tells of the benefits as well as the dysfunctions of practices that occurred over the decades, including the all-encompassing metric world of public schooling. The nightmare includes a technocratic system that provides a view of teaching and supervision dominated by politicians, entrepreneurs, and special interest foundations, and serves a view of schooling based on valuing of cultural uniformity, a punitive notion of accountability, and an uncritical perspective of patriotic nationalism, corporate thinking and class, race, and gender privilege. Foucault’s Panopticon is used as an analytic device for instructional supervision in order to portray a power relationship between the observer and the teacher. Not only does the nightmare reveal what has been happening over the past decades, but it also serves as a cautionary tale for the challenges we are now facing in the pandemic-era schooling of the 2020’s.

Las citas bibliográficas en la evaluación de la actividad científica: significado, consecuencias y un marco conceptual alternativo
Authors: Crisci Jorge V. , Katinas Liliana
Published: October 2020

Introducción y objetivos: En la evaluación de la actividad científica se aplican métricas basadas en el número de citas bibliográficas que reciben los artículos de una revista o los de un científico. Los objetivos de este trabajo son establecer el significado de una cita bibliográfica, discutir las consecuencias del uso de las métricas basadas en las citas bibliográficas como sinónimo de calidad científica incluyendo su efecto en el campo de la Botánica, y proponer un marco conceptual alternativo de evaluación de la actividad científica. 
Resultados: Ciertos factores impiden sustentar estadísticamente a esas métricas: tamaño de la potencial audiencia, variación de las prácticas de publicación y de citación entre las distintas disciplinas, la distribución estadística “long tail” de las citas, revista e idioma de la publicación y que una regularidad estadística observada tenderá a colapsar una vez que se ponga presión sobre ella al utilizarla con propósitos de control. Las consecuencias del uso de las citas para evaluar son: inhibición de la creatividad, cosificación del logro científico, valorar al producto en función del número de consumidores, las revistas con mayor número de citas se transforman en un factor de poder, desvalorización de los temas con valor local o regional, la ciencia se industrializa, las métricas reemplazan al juicio, y generar citas bibliográficas forma parte de los objetivos de un artículo científico. 
Conclusiones: El origen y la vigencia de estas métricas son la consecuencia de una sociedad de mercado es decir, una forma de vida organizada sobre la base del razonamiento y la moral del mercado y donde las relaciones humanas y sociales son meras relaciones de consumo.

The intensity of emotion: Altered motor simulation impairs processing of facial expressions in congenital facial palsy
Authors: Schiano Lomoriello Arianna , Caperna Giulio , De Stefani Elisa , Ferrari Pier Francesco , Sessa Paola
Published: October 2020

According to the models of sensorimotor simulation, we recognize others' emotions by subtly mimicking their expressions, which allows us to feel the corresponding emotion via facial feedback. In this contest, facial mimicry, which requires the implicit activation of the motor programs that produce a specific expression, is a crucial phenomenon occurring in emotion recognition, also concerning expression intensity. Consequently, difficulties to produce facial expressions would affect the experience of emotional understanding. In the present investigation, we recruited a sample (N = 11) of patients with Moebius syndrome (MBS), characterized by congenital facial paralysis, and a control group (N = 11) of healthy participants. By leveraging the MBS unique condition, we aimed at investigating the role of facial mimicry and sensorimotor simulation in creating a precise embodied concept of each emotion. The two groups underwent a sensitive facial emotion recognition task, optimally tuned to test sensitivity to emotion intensity and emotion discriminability in terms of their confusability with other emotions. Our study provides evidence of a deficit in recognizing emotions in MBS patients, expressed by a significant decrease in the rating of the intensity of three specific emotion categories, namely sadness, fear and disgust. Moreover, we observed an impairment in detecting these emotions, resulting in a stronger confusability of such emotions with the neutral and the secondary blended emotion. These findings provide support for embodied theories, which hypothesize that sensorimotor systems are involved in the detection and discrimination of emotions.

Published: October 2020

Introduction: Cervical cancer is one of the most prevalent cancer affecting women globally. It is the fourth most common cancer in women and the seventh overall. Cervical cancer can be cured and prevented by regular pelviccheck-up, screening test and vaccination against human papilloma virus. The objective of this study was to find out awareness regarding cervical cancer among women aged 18-49 years residing in Bharatpur MetropolitanCity-5, Chitwan.

Methods: A community based descriptive cross-sectional research design was used, 186 women were selected using simple random sampling method. Structured interview schedule was used to collect the data within 2weeks. The collected data was entered in Epi data 3.1 and exported into IBM SPSS version 20. Data was analysed in terms of descriptive and inferential statistics.

Results: The study revealed that 72.6% of the women were >30 years and 93% of women were literate, among them 35.2% had completed secondary level of education. It was found that only 28.0% of women had good level of awareness and 43.5% of them had poor level of awareness regarding cervical cancer. There was statistically significant relationship between level of awareness with age (p=0.029), ethnicity (p=0.013), marital status (p=0.018) and heard about organism that causes cervical cancer (p=<0.001).

Conclusions: Based on the findings of the study, it is concluded that, almost half of the women have poor level of awareness regarding cervical cancer. Hence, there is need for community awareness program on cervical cancer, its screening and preventive measures through the medium of health personnel, friends and mass media.

Authors: Song Jin-Qi , Zhou Ya-Nan , Tu Gang-Liang , Xu Hui
Published: October 2020

Background: In recent years, the incidence of prostate cancer (PCa) is increasing. Advanced PCa has a poor prognosis and high cost, which seriously affects the quality of life of patients. Therefore, how to improve the diagnosis rate and prognosis of early PCa is the focus of clinical research. This paper aims to investigate the value of  P504s, 34βE12, Ki-67 and prostate-specific antigen (PSA) in the diagnosis and prognosis of PCa.

Objective: To investigate the expression of P504s, 34βE12, Ki67 and PSA in prostate tissues and their clinical significance.

Methods: Twenty four cases in the study group were selected from PCa confirmed by pathology in the urology department of Chengde Affiliated Hospital from October 2018 to August 2020, and 33 cases of Benign Prostate Hyperplasia (BPH) confirmed by pathology in the same period were selected as the control group. The expression of P504s, 34βE12 and Ki-67 in prostate tissues were determined by immunohistochemistry.

Results: The positive expression rates of P504s, 34βE12 and TPSA or F/TPSA in PCa patients were 95.8%, 12.5% and 87.5%, respectively. The positive rates in BPH patients were 9.1%, 93.9% and 27.3%. The difference between the two groups was statistically significant (p<0.05). PCa bone or lymph node metastasis was positively correlated with Ki-67 (r=0.423, p<0.05) and Gleason score (r=0.446, p<0.05), indicating a stronger correlation with Gleasonscore.

Conclusion: The combined detection of P504s, 34βE12 and PSA is helpful for the diagnosis and differential diagnosis of PCa. High Gleason score and ki-67 expression may indicate high risk of PCa metastasis and poor prognosis.

Authors: Amatya Bibush , Sharma Rashmi , Syed MM Aarif , Rajbhandari Aasiya
Published: October 2020

Confluent and reticulated papillomatosis of Carteaud and Gougerot is a keratinization disorder with an infective aetiology. Patients present with hyperpigmented papules on the upper trunk and axillae that coalesce centrally and demonstrate reticulation peripherally. Diagnosis is based on clinical findings, characteristic histopathologic changes and response to therapy. We report a case of a young Nepali male who presented with gradual onset of asymptomatic raised dark brown lesions on his neck, trunk and axillae over the course of eight years. The condition was previously misdiagnosed as pityriasis versicolor and had received oral and topical antifungals. The diagnosis was revised to confluent and reticulated papillomatosis based on clinical and histopathological examination. He was subsequently started on oral minocycline 50 mg twice daily and nightly application of topical tretinoin 0.05% gel. There was complete resolution of all his lesions except for residual hyperpigmentation at the end of two months of therapy. There has been no relapse six months from the end of therapy.  This is to our knowledge, the first case of confluent and reticulated papillomatosis reported from Nepal. Oral minocycline and topical tretinoin should be considered first line in the treatment of confluent and reticulated papillomatosis.

Published: October 2020

Epidermodysplasia verruciformis (EDV) is a rare, inherited disorder that is characterized by an increased susceptibility to infection with specific human papilloma viruses (HPV) and a greater propensity for developing malignant skin tumors.

A 26 years old Nepalese male patient presented with complaints of multiple asymptomatic raised warty lesions on bilateral hands and multiple light colored flat to raised lesions present over the neck, trunk, bilateral extremities sparing the face and genitals.A skin biopsy was performed which revealed hyperkeratosis, focal parakeratosis, acanthosis, keratinocytes were swollen and irregularly shaped, had abundant basophilic cytoplasm and contained numerous round basophilic keratohyaline granules. Nuclei were large, round and empty with marginal distribution of chromatin, some were pyknotic.

Epidermodysplasiaverruciformis is a rare inherited disorder spread by HPV. It is characterized by hypopigmented or hyperpigmented macular lesions, pityriasis versicolor-like lesions and an early tendency to develop skin malignancies. The management of EDV includes early diagnosis, sun protection, life-long observation for the malignant transformation and therapeutic modalities like acitretin, imiquimod, topical retinoids, cryotherapy, etc.

Sturge Weber Syndrome – Roach’s Type II Variant
Authors: Bista Muna , Agrawal Sudha , Taparia Sweta
Published: October 2020

Sturge-Weber syndrome (SWS) is a neurocutaneous sporadic disorder caused by mutation in GNAQ gene responsible for persistence of vascular plexus around cephalic portion of neural tube. It has a wide spectrum of cutaneous, neurologic and ophthalmic manifestations, which may or may not be associated with one another. Roach scale has classified it into three types. Here, we present a case of Roach’s Type II variant of SWS with Port-wine stain (PWS) and ocular abnormalities without Central Nervous System (CNS) involvement. A 24 months old female presented with hemangioma involving the left side of face since birth. She had history of corneal edema and buphthalmos at two days of life. There was no history of seizure or developmental delay and Magnetic Resonance Imaging (MRI) of the head ruled out cranial hemangioma. Roach’s Type II is a rare variant of SWS and should be suspected in any case having PWS along the course of trigeminal nerve with congenital glaucoma because the neurologic involvement in a given case may vary from an absence to overt clinical manifestations with or without radiological changes. Due to its wide range of manifestations, a multidisciplinary approach is required for proper management of these patients.
Franjo Tuđman, demokršćanstvo i Hrvatska demokratska zajednica
Authors: Žižić Jakov
Published: October 2020

Ovaj se rad bavi odnosom Franje Tuđmana prema demokršćanskoj orijentaciji Hrvatske demokratske zajednice (HDZ) i njegovim razumijevanjem demokršćanstva. Prikazana su Tuđmanova stajališta o političkom identitetu HDZ–a te je objašnjena transformacija HDZ–a u stranku demokršćanske orijentacije na stranačkom saboru 1993. godine. Analiza je pokazala da programsko opredjeljenje HDZ–a za demokršćanstvo nije za Tuđmana značilo da ta stranka treba napustiti svoj nadideološki i svehrvatski politički identitet i pretvoriti se u izričito demokršćansku stranku. Istraživanje je također utvrdilo kako je Tuđmanovo razumijevanje demokršćanstva bilo puno bliže konfesionalnoj nego suvremenoj fazi demokršćanstva, premda je po nekim obilježjima Tuđman bio blizak i suvremenomu obliku demokršćanske ideologije.

Published: October 2020

Purpose: Interactive exercise technology (IET) is an effective and practical way to support physiotherapy for older adults. The purpose of this study was to use design thinking to collect feedback on the first iteration of an IET prototype from older adults and health professionals and to use that feedback to gain an understanding of their needs and values, with the goal of developing recommendations to inform the second iteration of the IET prototype. Method: This study was conducted using three steps of design thinking: (1) test, in which four focus groups were conducted, asking older adults and health professionals about their perspectives on an IET prototype; (2) empathize, in which the focus group discussions were recorded and transcribed and thematic content analysis was conducted; and (3) define, in which the needs and values of the participants were identified. Results: The participants were 19 health professionals and four older adults. Four themes, which represented the values that these groups held regarding IET design, were revealed: instruction, safety, accessibility, and motivation. Conclusions: Older adults and health professionals have specific needs for the design of IET, which should be considered in the development of future IET.

Published: October 2020

Purpose: Despite growing evidence that mirror therapy (MT) is effective for improving lower-extremity (LE) function in patients with stroke, it is not commonly used by physiotherapists. The purpose of this study was to determine whether change would occur in physiotherapists’ knowledge of, confidence in performing, and willingness to use MT for LE stroke rehabilitation after participating in a 1-hour educational module. Method: A convenience sample of physiotherapists working in neurorehabilitation was recruited for a single-group quasi-experimental pre–post study. Participants attended a 1-hour educational module on MT. Therapists’ perceptions of the use of MT were assessed by questionnaire before and after they participated in the module. A follow-up telephone survey was conducted after 3 months to determine how many participants had actually used MT in their practice. Results: Nine physiotherapists participated in this study. Statistically significant increases were found in their perceived knowledge of, confidence in, and willingness to use MT. At the 3-month follow-up, three participants had used MT with patients with LE hemiparesis. Conclusions: Therapists’ knowledge of and attitudes toward MT for LE stroke rehabilitation changed favourably after participating in a 1-hour educational module. The module also led some therapists to make a change in practice at 3 months.

Authors: Kaptanoglu Mustafa , Odabasi Akin
Published: October 2020

In this study, the usability of a new submerged arc welding flux was investigated to develop the surface properties of Hardox steels. In the hardfacing welding processes for Hardox 400 steel, four welding speeds resulting in varied heat inputs were applied. Through an analysis of the chemical composition, microstructure examinations, hardness measurements and wear tests, the possibility of hardfacing properties control due to the change of process parameters were determined. In the experimental studies, the hardness of the hardfacing obtained at a welding speed of 30 cm × min-1 was measured as 42 HRC while the hardness of the hardfacing obtained at a welding speed of 48 cm × min-1 was measured as 57 HRC. Moreover, in the wear tests, results consistent with the hardness values were obtained. It was understood in the light of the results that the use of high carbon ferro-chromium 20 wt.-% in a submerged arc welding flux mixture may be useful in improving hardness and wear properties of Hardox steels through hardfacing welding processes.

Published: October 2020

This study investigated the performance of the grinding parameters used in the cylindrical grinding process of AISI 5140 steel and identified optimum grinding conditions via the Taguchi optimization method. Experiments were carried out via the L18 orthogonal array. Control factors for optimum surface roughness (Ra) values were determined by using the Taguchi method. Two different grinding wheels (SiC and Al2O3), three different cryogenic samples (CHT, DCTT-15 and DCTT-30) and depth of cuts (100, 200 and 300 μm) were selected as control factors. The cylindrical grinding test results showed that optimal Ra values were obtained on specimens cryogenically treated for 30 h (DCTT-30). Linear and quadratic regression analyses were conducted for the experimental results. The correlation coefficients (R2) were found to be 0.957 and 0.993 with linear and quadratic regression models, respectively. Finally, confirmation tests were performed and showed that the optimization had been successfully implemented.

Published: October 2020

The effects of H2O2 solution addition and temperature on electrolytic pickling via Na2SO4 solution to eliminate the metal oxide layers of an annealed 304L stainless steel were investigated by polarization technique. The experimental conditions involved a pure 190 kg × m-3 Na2SO4 solution and a mixture of 190 kg × m-3 Na2SO4+ 10 kg × m-3 H2O2at 298, 318 and 333 K and pH 4. It was found that the addition of a 10 kg × m-3 H2O2 solution in 190 kg × m-3 Na2SO4 solution and an increase in temperature resulted in a decrease in the passive region of the polarization curves. The results from the SEM images, the XRD patterns and root-meansquare roughness showed that the surface of the annealed 304L stainless steel was smoother and fewer remaining oxide scales was found when pickling in 190 kg × m-3 Na2SO4 + 10 kg × m-3 H2O2 solution. However, no effects of the addition of 10 kg × m-3 H2O2 solution in 190 kg × m-3 Na2SO4 solution and temperature on pickling time at 298, 318 and 333 K were observed.

Hydronephrosis results from a total or partial obstruction of the lower urinary Hydronephrosis results from total or partial obstruction of the lower urinary tract, which promotes progressive dilation of the renal pelvis, and consequently, compression and atrophy of the parenchyma. Although its casuistry is low, its diagnosis is favored by clinical, laboratory and imaging exams. The aim of this study was to report the case of an adult mixed breed (SRD) dog with severe hydronephrosis that culminated in unilateral right nephrectomy. The animal had a distended abdomen with no painful response and a flank wound through which it drained blood and purulent secretion. Laboratory tests indicated normochromic normocytic anemia, leukocytosis with deviation to the left and increased plasma proteins. During the surgery, the right kidney was attached to the peritoneum, spleen, pancreas, omentum, liver and stomach. There were no free abdominal fluids or signs of peritoneal and / or retroperitoneal inflammation. Loss of renal parenchyma with replacement by intense fibrous connective tissue was verified microscopically. This report describes the evolution of this case from its initial consultation to the ninety days after the postoperative period. The underlying cause of the disease has not been clarified.
Síndrome braquicefálica em cães: Revisão
Authors: Bilhalva Maurício
Published: October 2020

Brachycephalic dogs have become increasingly desirable among pet owners. However, one of the main diseases that affect these animals is brachycephalic syndrome. This condition causes an increase in the resistance to the passage of air through the airways in these animals, caused by several respiratory changes, such as narrowed nostrils in 42.5% to 85.2% of the animals, 86.3% to 100% develop prolongation of soft palate, 8.2% to 38.2% tracheal hypoplasia and 54.1% to 66% develop eversion of the laryngeal sacs. Physical examination is essential, however, as complementary tests for the diagnosis of the syndrome, radiography, endoscopy, blood count and electrocardiogram may be ordered, which exhibit several changes of greater and lesser degree. Surgical treatment is the only curative method, but conducts must be adopted to improve the living conditions of the animals, such as airy places, with mild temperatures and to avoid excessive exercise. The prognosis varies according to the severity of the symptoms, with or without surgical complications. Thus, the best form of prevention is not to subject these animals to reproduction.

The fortieth anniversary of Sartre’s death, on April 15 of this year, found much of the world in lockdown in response to a new virus, Covid-19, which has changed humanity’s situation on this planet in ways we will be struggling to elucidate for years to come. In these unprecedented circumstances, Sartre’s thought has been an obvious resource to help us understand the impact and ramifications of this pandemic. The virus has been an unsparing indicator in itself of social injustice, unmasking the pious platitudes of our advanced, modern democracies. In the United States in particular, the reality is truly ugly. Covid-19 has shed pitiless light on the disparity between affluent white communities, able to “shelter in place” and avoid putting their members at risk of infection, and less affluent black and brown districts, where workers on subsistence salaries, often without health-care benefits, have been forced to work in unsafe conditions, with terrible consequences for them and their families. Living in the “richest” country on earth, we can imagine only too easily Sartre’s vitriolic assessment of America in its present crisis. And it is just as easy to imagine the fervor with which he would have embraced the Black Lives Matter protests that erupted all over the world, provoked by the 8 minute 46 second video clip that showed the matter-of-fact murder by asphyxiation of George Floyd by white police officers in Minneapolis.
CORRELATES AND CONSTRAINTS OF EFFECTIVE AGRICULTURAL LOAN REPAYMENT IN CAMEROON
Authors: Tambi Mbu Daniel
Published: October 2020

This study has been carried out with the objective of examining the factors influencing effective agricultural loan repayment in MFIs and constraints associated with agricultural loan acquisition in West region, Cameroon. From primary surveyed data, a probit model was used to analyze the result. We observed that farm production, training, size of farmland; male household head, married head, interest rate and the loan duration are strongly correlating with agricultural loan repayment. Inadequate agricultural funds, much expenditure on farm competition and improper interference of the third party in the decision of loan approval are the constraints associated with agricultural loan. We suggest that, the decision makers should create more specialized structures in charge of agricultural loan as well as reduce the rate of interest. This is a wise step, towards food security and increase family welfare and improved job market.

The purpose of this study was to determine the effect of the TANDUR learning model assisted by GeoGebra on mathematics learning outcomes in terms of student learning independence which is a quasi-experimental research. The number of respondents in this study were 71 students. Collecting data on learning independence is collected through a questionnaire, and data on mathematics learning outcomes are collected through tests of mathematics learning outcomes in the cognitive domain. Data analysis was performed using two-way analysis of variance (ANAVA) with the help of SPSS, at a significance level of 5%. The results show that the learning outcomes of students who use the TANDUR learning model assisted by GeoGebra are better than the learning outcomes of students who use conventional learning models, student learning outcomes using the TANDUR learning model assisted by GeoGebra are better than using conventional learning models in students who have learning independence high, and the learning outcomes of students who use conventional learning models are better than students who use the GeoGebra-assisted TANDUR learning model for students who have low learning independence.

Authors: Fadillah Ahmad , Nopitasari Dian , Pradja Barra P
Published: October 2020

The purpose of this study is to describe the mathematical disposition of students who use blended learning during the Covid-19 pandemic. This research is a descriptive qualitative research. The research subjects were four students from the sixth semester of mathematics education study program. The research instrument was a student mathematical disposition questionnaire. The results of the study concluded that the average level of mathematical disposition of students was classified as moderate. If seen from the indicators, only the monitor and evaluate indicators are classified as high category. Indicators of persistence and perseverance, especially when lecturers present interesting contextual problems. Many indicators of curiosity arise when lecturers invite students to be active in learning, for example students are invited to study in groups. Many self-confidence indicators appear when lecturers ask students questions. While many flexible indicators appear when lecturers give open ended questions.
Identification and Control of Coral Ardisia (Ardisia crenata): A Potentially Poisonous Plant.
Authors: Sellers Brent A. , Lancaster Sarah , Langeland Kenneth A. , Ferrell Jason A. , Meisenberg Michael , Walter Joseph
Published: October 2020

Coral ardisia, also known as coral berry, spice berry, and scratchthroat, was introduced to Florida in the early 1900′s for ornamental purposes. Since then, it has escaped cultivation, and it is found in hardwood hammocks and other moist, natural-wooded areas and grazing lands. Although there is no published literature supporting the theory that coral ardisia is toxic, it is suspected that the berries and/or foliage are poisonous to livestock, pets, and humans.

Stewardship Ecosystem Services Study: Carbon Stores on Florida Forest Stewardship Program Lands
Authors: Timilsina Nilesh , Escobedo Francisco J. , Adams Alison E. , Delphin Sonia
Published: October 2020

Nonindustrial private forestlands in Florida provide many environmental benefits, or ecosystem services. Ecosystem services are benefits from nature that are directly enjoyed, consumed, or used by humans, such as water quality improvement or protection, recreation, biodiversity, and even timber. Another benefit from forests that is gaining interest is their ability to store carbon through the photosynthetic capture of carbon dioxide, a greenhouse gas, in tree, plant, and soil biomass. The carbon dioxide that is stored over the life of a forest, called carbon stocks, is not only important for mitigating greenhouse gas contributions to climate change, but it can also be valued in several markets and incorporated into environmental policy instruments.
