Authors: Mazinani Mitra
Published: September 2020

UNSTRUCTURED

During late 2019, the first cases of the Coronavirus disease-2019 (COVID-19) was observed in a Seafood Market in Wuhan. As the first cases took place in a seafood market that consumed live animals, it has been identified as a zoonotic disease. Some reports suggested snakes were the animal host, while others reported bat and pangolin were the sources of infection because coronavirus-origin of these two animals had similar genomic sequences to COVID-19.

Authors: Lee Naae , Oh Seung-Won , Cho Belong , Myung Seung-Kwon , Hwang Seung-Sik , Yoon Goo Hyeon
Published: September 2020

BACKGROUND

Concern regarding the reliability and accuracy of the health-related information provided by online newspaper articles has increased. Numerous criteria and items have been proposed and published regarding the quality assessment of online information, but there is no standard quality assessment tool available for online newspapers.

OBJECTIVE

This study aimed to develop the Health Information Quality Assessment Tool (HIQUAL) for online newspaper articles.

METHODS

We reviewed previous health information quality assessment tools and related studies and accordingly developed and customized new criteria. The interrater agreement for the new assessment tool was assessed for 3 newspaper articles on different subjects (colorectal cancer, obesity genetic testing, and hypertension diagnostic criteria) using the Fleiss κ and Gwet agreement coefficient. To compare the quality scores generated by each pair of tools, convergent validity was measured using the Kendall τ ranked correlation.

RESULTS

Overall, the HIQUAL for newspaper articles comprised 10 items across 5 domains: reliability, usefulness, understandability, sufficiency, and transparency. The interrater agreement for the article on colorectal cancer was in the moderate to substantial range (Fleiss κ=0.48, SE 0.11; Gwet agreement coefficient=0.74, SE 0.13), while for the article introducing obesity genetic testing it was in the substantial range, with values of 0.63 (SE 0.28) and 0.86 (SE 0.10) for the two measures, respectively. There was relatively low agreement for the article on hypertension diagnostic criteria at 0.20 (SE 0.10) and 0.75 (SE 0.13), respectively. Validity of the correlation assessed with the Kendall τ showed good correlation between tools (HIQUAL vs DISCERN=0.72, HIQUAL vs QUEST [Quality Evaluation Scoring Tool]=0.69).

CONCLUSIONS

We developed a new assessment tool to evaluate the quality of health information in online newspaper articles, to help consumers discern accurate sources of health information. The HIQUAL can help increase the accuracy and quality of online health information in Korea.

Reporting of Differences in Taste Between Branded and Unbranded Cigarettes by Smokers Blinded to Cigarette Branding: Within-Person, Randomized Crossover Study (Preprint)
Authors: BinDhim Nasser F , Althumiri Nora A , Basyouni Mada H , Almubark Rasha A , Alkhamaali Zaied , Banjar Weam , Zamakhshary Mohammed , AlKattan Khaled M
Published: September 2020

BACKGROUND

Saudi Arabia implemented a plain tobacco packaging regulation, one of the World Health Organization’s recommended initiatives to help reduce smoking rates, in August 2019. A few weeks after implementation, a large number of smokers complained via various media channels, especially social media (eg, Twitter), that an extreme change in cigarette taste had occurred, frequency of coughing had increased, and for some, shortness of breath had led to hospitalization.

OBJECTIVE

The main objective is to determine whether smokers blinded to cigarette branding report differences in taste between branded and unbranded cigarettes. The secondary objective is to observe the frequency of immediate cough or shortness of breath.

METHODS

This study employed a within-person, randomized crossover design that recruited current smokers 18 years and older who were cleared upon physical assessment before the experiment. Participants received 6 sequences of different random exposures (3 puffs) to 3 plain-packaged cigarettes (2 from their favorite brand and 1 from another brand as a control) and 3 branded cigarettes (2 from the favorite brand and 1 from another brand as a control). Participants wore virtual reality goggles accompanied by special software to alter visual reality and gloves to alter the touch sensation.

RESULTS

This study recruited 18 participants, measured at 6 time points, to produce 108 experiments. Participants were not able to identify the correct type of cigarettes (plain or branded, estimate of fixed effect=−0.01, P=.79). Moreover, there were no differences in the ability of the participants to identify their favorite brand (t107=−0.63, mean 0.47, P=.53). In terms of immediate coughing, out of the 108 experiments, 1 episode of short coughing was observed, which was attributed to the branded cigarette, not the plain-packaged cigarette.

CONCLUSIONS

After controlling the visual and touch sensations, participants were not able to differentiate between branded and plain-packaged cigarettes in terms of taste or inducing immediate shortness of breath or cough. Interestingly, participants were not able to identify their favorite brand.
Demystifying the Dark Web Opioid Trade: Content Analysis on Anonymous Market Listings and Forum Posts (Preprint)
Authors: Li Zhengyi , Du Xiangyu , Liao Xiaojing , Jiang Xiaoqian , Champagne-Langabeer Tiffany
Published: September 2020

BACKGROUND

Opioid use disorder presents a public health issue afflicting millions across the globe. There is a pressing need to understand the opioid supply chain to gain new insights into the mitigation of opioid use and effectively combat the opioid crisis. The role of anonymous online marketplaces and forums that resemble eBay or Amazon, where anyone can post, browse, and purchase opioid commodities, has become increasingly important in opioid trading. Therefore, a greater understanding of anonymous markets and forums may enable public health officials and other stakeholders to comprehend the scope of the crisis. However, to the best of our knowledge, no large-scale study, which may cross multiple anonymous marketplaces and is cross-sectional, has been conducted to profile the opioid supply chain and unveil characteristics of opioid suppliers, commodities, and transactions.

OBJECTIVE

We aimed to profile the opioid supply chain in anonymous markets and forums via a large-scale, longitudinal measurement study on anonymous market listings and posts. Toward this, we propose a series of techniques to collect data; identify opioid jargon terms used in the anonymous marketplaces and forums; and profile the opioid commodities, suppliers, and transactions.

METHODS

We first conducted a whole-site crawl of anonymous online marketplaces and forums to solicit data. We then developed a suite of opioid domain–specific text mining techniques (eg, opioid jargon detection and opioid trading information retrieval) to recognize information relevant to opioid trading activities (eg, commodities, price, shipping information, and suppliers). Subsequently, we conducted a comprehensive, large-scale, longitudinal study to demystify opioid trading activities in anonymous markets and forums.

RESULTS

A total of 248,359 listings from 10 anonymous online marketplaces and 1,138,961 traces (ie, threads of posts) from 6 underground forums were collected. Among them, we identified 28,106 opioid product listings and 13,508 opioid-related promotional and review forum traces from 5147 unique opioid suppliers’ IDs and 2778 unique opioid buyers’ IDs. Our study characterized opioid suppliers (eg, activeness and cross-market activities), commodities (eg, popular items and their evolution), and transactions (eg, origins and shipping destination) in anonymous marketplaces and forums, which enabled a greater understanding of the underground trading activities involved in international opioid supply and demand.

CONCLUSIONS

The results provide insight into opioid trading in the anonymous markets and forums and may prove an effective mitigation data point for illuminating the opioid supply chain.

Published: September 2020

Background and objectives

Many patients, providers, and potential living donors perceive the living kidney donor evaluation process to be lengthy and difficult to navigate.

Design, setting, participants, & measurements

We sought consensus on key terms and process and outcome indicators that can be used to measure how efficiently a transplant center evaluates persons interested in becoming a living kidney donor. Using a RAND-modified Delphi method, 77 participants (kidney transplant recipients or recipient candidates, living kidney donors or donor candidates, health care providers, and health care administrators) completed an online survey to define the terms and indicators. The definitions were then further refined during an in-person meeting with ten stakeholders.

Results

We identified 16 process indicators (e.g., average time to evaluate a donor candidate), eight outcome indicators (e.g., annual number of preemptive living kidney donor transplants), and two measures that can be considered both process and outcome indicators (e.g., average number of times a candidate visited the transplant center for the evaluation). Transplant centers wishing to implement this set of indicators will require 22 unique data elements, all of which are either readily available or easily collected prospectively.

Conclusions

We identified a set of indicators through a consensus-based approach that may be used to monitor and improve the performance of a transplant center in how efficiently it evaluates persons interested in becoming a living kidney donor.
Escritos y secciones de moda en la prensa yucateca: el refinamiento del gusto y la sensibilidad estética de los seguidores de las modas extranjeras, 1840-1920
Authors: Vanegas Durán Claudia Marcela
Published: September 2020

El artículo analiza una serie de escritos y secciones de modas publicados en la prensa yucateca desde 1840 hasta 1920. Los textos formaron parte de un discurso didáctico que pretendía refinar el gusto y la sensibilidad estética de los peninsulares. Sus escritores cumplieron la función de intermediarios culturales entre el atavío de moda en Europa y las  prácticas locales al orientar a los lectores en el complejo y variable mundo de trajes y accesorios que comenzaban a comercializarse en las tiendas y talleres locales. Su contenido refleja cómo el uso de nuevos modelos fue una de las formas a través de la cual se materializaba la vida moderna y civilizada, lo que define a la indumentaria como uno de los dispositivos de distinción social y de orientación de los gustos, en particular de los grupos sociales de élite o aquellos que aspiran a serlo.
The Anatomy of a National Crisis: The Canadian Federal Government’s Response to the 2015 Kurdi Refugee Case
Authors: Siddiqi Sara , Koerber Duncan
Published: September 2020

Background A photograph of Alan Kurdi, a Syrian boy found dead on a Turkish beach, sparked a major Canadian political crisis. During a federal election campaign, Prime Minister Stephen Harper and Minister of Citizenship and Immigration Chris Alexander responded quickly to the incorrect implication that the government’s immigration policies caused the boy’s death.

Analysis This article analyzes the appropriateness of Harper’s and Alexander’s response strategies during the hours right after the crisis broke.

Conclusion and implications This article argues that the politicians faced an unusual challenge because, although the government’s policies had not actually caused the crisis, government leaders had to respond as if they had. Harper and Alexander mostly followed best practices but shifted the blame to the greater refugee crisis, which came across as disingenuous.

Authors: Oldring Amanda , Milekhina Antonina , Brand Alexander
Published: September 2020

Background Although early warning has been studied on Twitter, research focused on Canada is rare. British Columbia, Canada, is vulnerable to tsunamis, and warning systems are not ubiquitous. Establishing pre-event networks can contribute to understanding early warning dissemination potential in the province.

Analysis This study locates a 1,932 follower network for @NWS_NTWC, a Twitter handle for the U.S. National Tsunami Warning Center, and the province’s primary tsunami warning notification account. A profile content analysis identifies stakeholders and maps locations, and a network analysis describes interconnections by role, country, and community type (rural or urban).

Conclusion and implications The results describe how networks can optimize warnings via Twitter. Key outcomes include a longitudinal baseline, network-driven decision-making techniques, strategies for alerting at-risk areas, and a method for detecting influential users.
Crisis, Communication, and Canadian Hospitals: An Analysis and Evaluation of Risk Preparedness and Crisis Communication Efforts of Ontario Hospitals
Authors: Dobosz Sebastian
Published: September 2020

Background While hospitals are complex and unique organizations, they are not often the subjects of crisis communication research.

Analysis Through an analysis of each stage of the crisis communication process (preparedness, execution, and post-crisis), this study seeks to analyze and evaluate the crisis response of Canadian hospitals from a strategic communication perspective.

Conclusions and implications This study reflects the findings of similar research in the field, confirming that hospitals in Ontario are indeed more prepared to face issues and crises that they have faced in the past. This study also demonstrates how integration between crisis communication and operational crisis management helps to foster a robust crisis preparedness strategy and a unified crisis response.
Informationally restricted quantum correlations
Authors: Tavakoli Armin , Zambrini Cruzeiro Emmanuel , Bohr Brask Jonatan , Gisin Nicolas , Brunner Nicolas
Published: September 2020

Quantum communication leads to strong correlations, that can outperform classical ones. Complementary to previous works in this area, we investigate correlations in prepare-and-measure scenarios assuming a bound on the information content of the quantum communication, rather than on its Hilbert-space dimension. Specifically, we explore the extent of classical and quantum correlations given an upper bound on the one-shot accessible information. We provide a characterisation of the set of classical correlations and show that quantum correlations are stronger than classical ones. We also show that limiting information rather than dimension leads to stronger quantum correlations. Moreover, we present device-independent tests for placing lower bounds on the information given observed correlations. Finally, we show that quantum communication carrying log⁡d bits of information is at least as strong a resource as d-dimensional classical communication assisted by pre-shared entanglement.
Reaction of a 3-aryilidene-2-thiohydantoin derivative with polymeric trans-[CuCl2(DMSO)2]n complex: Unexpected isomerization to dinuclear cis-[{CuCl(DMSO)2}(μ-Cl)]2
Authors: Stanic Petar , Rodic Marko , Soldatovic Tanja , Pavic Aleksandar , Radakovic Natasa , Smit Biljana , Zivkovic Marija
Published: September 2020

The 3-arylidene-2-thiohydantoin derivative, 3-[(2-hydroxybenzylidene) amino]-2-thioxoimidazolidin-4-one, was synthesized in a two-step condensation reaction of 2-hydroxybenzaldehyde, thiosemicarbazide and ethyl chloroacetate. The ligand was structurally characterized by NMR and IR spectroscopy, as well as by elemental analysis. In the reaction of the well-known polymeric trans-[CuCl2(DMSO)2]n complex with the polydentate thiohydantoin type ligand, instead of the corresponding copper thiohydantoin complex, unexpectedly, the dinuclear cis-[{CuCl(DMSO)2}(?-Cl)]2 complex (1) was formed predominantly as the final stable product. The structure of the complex 1 was confirmed by single crystal X-ray diffraction analysis. The cis-complex is obtained through assisted isomerization of the trans-form, in which the thiohydantoin derivative has a crucial role.
Experimental study on combustion of CH4/NH3 fuel blends in an industrial furnace operated in flameless conditions
Authors: Slefarski Rafal , Czyzewski Pawel , Golebiewski Michal
Published: September 2020

This paper presents the results of an experimental study on the combustion process of methane mixed with NH3 in flameless mode. At a time of striving for CO2-free power, NH3 became a potential energy storage carrier fuel from renewable sources. Flameless combustion features low emissions and is a very efficient technology used in the power sector, as well as steel production, ceramics, etc. Industrial furnaces were tested in the context of pure methane combustion with an addition of NH3, up to 5%. Flameless combustion conditions were achieved with a regenerative gas burner system (high regenerative system). The burner consists of four ceramic regenerators allowing for continuous preheating of air, even up to 50 K lower than the temperature of the combustion chamber wall. Constant power of the introduced fuel was kept at 150 kW and the fuel-air equivalence ratio ranged from 0.75 to 0.95. The results have shown a growth of molar fraction of NO in flue gases when NH3 content in the fuel rose. The increase is more significant for the tests with a higher amount of oxygen in the combustion chamber (a lower fuel-air equivalence ratio). An addition of 5% of NH3 into the fuel caused an emission of NO at the levels of 113 ppmv and 462 ppmv (calculated to O2 = 0%), respectively for low and high fuel-air equivalence ratios.
An exergy-rational district energy model for 100% renewable cities with distance limitations
Authors: Kilkis Birol
Published: September 2020

While moving towards 100% renewable district energy systems at low temperatures, the exergy of the district energy may decrease below the pumping exergy requirement, which eliminates the benefits of using low-exergy renewables. Because such a possibility may not be revealed by the First Law, an exergy-based holistic model for district energy systems was developed. Four tiers, namely renewable energy resources, energy conversion and storage, main district network, and the low-exergy district are identified. Each tier is indexed to the optimum plant-to-district distance for maximum exergy-based performance with minimum CO2 emissions responsibility. This model further optimizes the temperature peaking with heat pumps versus HVAC equipment oversizing and determines the optimum mix of renewables. Three alternatives of conveying and distributing exergy to the district were considered, namely: electricity only, electricity and heat with or without temperature peaking or equipment oversizing, and electricity, heat, and cold. Comparisons showed that the choice primarily depends upon the district size, district-to-plant distance, climatic conditions, local availability of RES, optimum supply temperature, and thermal condition of the buildings. Another algorithm optimizes the thermal insulation thickness in terms of equipment oversizing and temperature-peaking.

Published: September 2020

The research is based on the need to update the understanding of the adaptive potential of the individual at the stage of professionalization of college students. The study was conducted to analyse the dynamics of educational adaptation on the example of indicators of adaptation in the study group and adaptation to educational activities, using the methodology of T.D. Dubovitskaya and A.V. Krylova. The authors tested the assumption that the result of specially organized psychological and pedagogical support might be an increase in the indicators of educational adaptation of first-year students. The dynamics of educational adaptation was assessed by comparing the indicators of students’ adaptation to educational activities and in the study group, obtained before and after the implementation of psychological and pedagogical support aimed at strengthening the components of self-regulation, developing social communication and skills and skills of working with information. Statistical analysis using the Wilcoxon T-test was used to assess the significance of differences. As a result of the research, based on qualitative and statistical analysis, it can be concluded that as a result of psychological and pedagogical support, students have a positive dynamics of educational adaptation, in particular, indicating that the girls’ adaptation to educational activities is more successful than adaptation in a group. The practical significance of the research is to justify the applicability of the system of psychological and pedagogical support for first-year College students to maintain adaptation to the socio-cultural environment of the university by creating conditions for strengthening the subjective component of educational motivation. It contributes to a better understanding of the effectiveness of their own efforts to work with educational material; creating conditions for strengthening self-regulation skills in the course of psychological counselling of students (as a direction of psychological and pedagogical support), for developing the cognitive potential of the individual and strengthening communication skills in the course of general support. Moreover, the study confirms the possibility of using the methodology for evaluating students’ educational motivation to track its dynamics using both qualitative and quantitative indicators.
Reliability of kinetic measurements of healthy dogs examined while walking on a treadmill
Authors: Pietsch Sebastian , Steigmeier-Raith Stephanie , Reese Sven , Meyer-Lindenberg Andrea
Published: September 2020

OBJECTIVE

To investigate whether an actual improvement in gait could be differentiated from physiologic differences or habituation effects during gait analysis of dogs.

ANIMALS

11 healthy dogs.

PROCEDURES

On 4 examination days, kinetic parameters were measured while dogs were walking on a treadmill. Differences in mean parameter values and habituation effects (ie, effect sizes) were quantified and compared among examination days. Coefficients of variation for repeated measurements were calculated to determine measurement reproducibility, and minimum differences were calculated to distinguish between physiologic fluctuation and an actual change in gait pattern.

RESULTS

Among the 4 examination days, mean absolute differences in peak vertical force and vertical impulse (VI) varied from 1.5% to 5.3% of body weight (BW) and 0.9% to 1.8% of BW·s, respectively. Mean absolute differences in the percentage of stance-phase duration (%SPD) and relative stride length (RSL) varied from 0.9% to 3.2% and 1.7% to 3.0%, respectively. Reproducibility of parameter measurements was good. Values for %SPD had the lowest amount of dispersion and largest effect size, suggesting a habituation effect for this parameter. Calculated minimum differences among the days for peak vertical force, VI, %SPD, and RSL did not exceed 9.9% of BW, 3.3% of BW·s, 5.8 percentage points, and 5.2 percentage points, respectively.

CONCLUSIONS AND CLINICAL RELEVANCE

The %SPD of healthy dogs walking on a treadmill was the most sensitive and diagnostically reliable of the measured kinetic parameters, in contrast to VI and RSL. Findings suggested that actual changes can be distinguished from random physiologic fluctuations during gait analysis of dogs.

Published: September 2020

Rabies is enzootic in over one hundred countries worldwide. In the European Union/European Economic Area (EU/EEA), the vast majority of human rabies cases are travellers bitten by dogs in rabies-enzootic countries, mostly in Asia and Africa. Thus, EU/EEA travellers visiting rabies enzootic countries should be aware of the risk of being infected with the rabies virus when having physical contact with mammals. They should consider pre-exposure vaccination following criteria recommended by the World Health Organization and if unvaccinated, immediately seek medical attention in case of bites or scratches from mammals. As the majority of the EU/EEA countries are free from rabies in mammals, elimination of the disease (no enzootic circulation of the virus and low number of imported cases) has been achieved by 2020. However, illegal import of potentially infected animals, mainly dogs, poses a risk to public health and might threaten the elimination goal. Additionally, newly recognised bat lyssaviruses represent a potential emerging threat as the rabies vaccine may not confer protective immunity. To support preparedness activities in EU/EEA countries, guidance for the assessment and the management of the public health risk related to rabies but also other lyssaviruses, should be developed.

Informed Change: Exploring the Use of Persuasive Communication of Indigenous Cultures Through Film Narratives
Authors: H Bickford Sonja , Warren Michelle
Published: September 2020

Aim/Purpose: There is a need to find a way to utilize narrative storytelling in film to make students more aware of the impacts of global problems and how they are perceived.

Background: Two films from the year 2015 from two very different places in the world explore the encroachment and secondary effects of urban civilization upon indigenous cultures.

Methodology: An interpretive, qualitative, methodology was used in addressing and discussing the use of these two films as a persuasive communication teaching aid.

Contribution: This paper offers an approach to using narratives of films on indigenous issues in education to inform students about real-world issues and the wide impacts of those on various cultures and populations.

Findings: Through the discussion of the two films, we suggest that using films with indigenous themes is beneficial to a course curriculum in a variety of subjects from communication to history and politics, to help students visualize the problems at hand. Anecdotally, the authors note that students are more engaged and willing to discuss topics if they have watched films or clips that deal with those topics than if they have simply read about them.

Recommendation for Researchers: Technology and use of visuals are used as teaching tools in a variety of fields. Film narratives can be used as a teaching tool in multiple fields and provide insight about a variety of ideas. Identifying films such as those with indigenous themes provides an example of how one film can bring up multiple, real-world, topics and through led discussion student reflection can potentially lead to self-insights and have lasting impacts.

Future Research: Additional research and assessment can be done on the impact of teaching with films and their compelling story telling of issues, and what types of questions should be asked to maximize learning and the impact of film narratives.

Authors: Dodokhov Vladimir Vladimirovich , Pavlova Nadezhda Ivanovna , Kalashnikova Lyubov Aleksandrovna
Published: September 2020

The article presents the results of DNA microsatellite polymorphism with the use of a commercial kit containing 16 markers: Rt6, BMS1788, Rt30, Rt1, Rt9, C143, Rt7, OheQ, FCB193, C217, Rt24, BMS745, NVHRT16, T40 и C276. The study object is domestic reindeer procured from Chukotka AO to Nizhnekolymsky district of the Republic of Sakha (Yakutia) to refresh the blood of Chukotka reindeer under the rehabilitation program and improvement of reindeer breeding condition. Allele frequency, indicators of observed and expected heterozygosity, fix index and polymorphism were calculated. The calculation of allele frequencies showed that microsatellite markers have a wide range of alleles and high informative value for detecting genetic differences between animals and groups of animals. A total of 116 alleles were identified, which gave an average of 7.25 alleles per locus, and the number of effective alleles was 3.9. Indicators of observed and expected heterozygosity were 0.713 and 0.691. The highest number of alleles 12 and 13 were found in locus OheQ и BMS1788 and the smallest in locus C 143, which had 2 alleles. Also, 3 alleles were identified in locus C217 and C32.

Motor education through basketball contributes to the development of manual coordination, balance and laterality, organization in space and time, the latter focusing on the body scheme that children are primarily concerned with at primary school. Practicing, by using the simple means of basketball, improves the primordial sensory skills; sophisticated and global motor activities improve the basic motor skills and facilitate the perceptual-motor integration, which is the starting point for the cognitive functions. This paper aims at designing and implementing a kinetic program of stimulation using simple means of basketball in order to improve the balance and laterality of children with intellectual disabilities. The results obtained revealed the efficientization of the fundamental motor skills (locomotion, handling and stability) of the research subjects.

The model is solved using both MILP with the Xpress software and genetic algorithms with the Evolver solver.  The model is built for Evolver in MS Excel. Results of both solving tools are compared to analyze the performance of each of them. The accuracy and capability of the model to solve the MPS problems have been verified through the discussion of its results logicality for different cases of different patterns.
STOCHASTIC FRONTIER APPROACH OF VALUE ADDED MEASURES OF SUGAR PRODUCTION IN BANGLADESH: AN EMPIRICAL ANALYSIS
Authors: Sabur Abdus , Sina Abu
Published: September 2020

An attempt has been taken to explore the causes of inefficiency of management of sugar industry in Bangladesh by applying Stochastic Frontier Approach (SFA) that contains three steps of estimation.  According to value of output measurement by SFA,  parameter was found with positive values indicating potential production deferred from actual production. The return to scale of the sample was estimated 1.84 implied increasing returns to scale. The parameter () of OLS for the sample was found less than that of MLE for the cause of below position of potential output. (Lambda) was the ratio of variance of industry specific production behaviors (u) to the variance of statistical noise (v). Here that ratio was found 1.69 and 1.11 for the half-normal and truncated normal distribution which indicated that there were impacts due to inefficiency of the management dominated by random disturbances of the sugar industry in Bangladesh. The value of  was estimated 74 percent and 55 percent for half normal and truncated normal indicating 74 percent and 55 percent output in sugar production were due to inefficiency of the management. The parameter () was found negative for both the methods which indicated that the technical efficiency was decreasing over the time. The mean technical efficiency of sample was 54.45 percent and 35.45 percent for the half normal and truncated normal distribution. This further indicated that the management could increase the production level by 45.55 percent and 64.55 percent respectively using same level of inputs. The suggestion and recommendation has been provided to improve managerial skills, increase skilled manpower, introduce higher sucrose content cane, modernization of machineries and reduction of overhead cost.

Günümüzde teknoloji eğitim alanında da yaygın bir şekilde kullanılmaktadır. Eğitim Bilişim Ağı (EBA) eğitim alanında kullanılan teknolojik platformlardan biridir. Okuma becerisi, bu platformda uzaktan eğitim ile Türkçe dersi üzerinden
öğrencilere kazandırılmaktadır. Okuma, okula başladığımız dönemde kazandığımız ve hayatın her alanında kullanma ihtiyacı duyduğumuz bir beceridir. İlköğretim döneminde edinilen bu becerinin, bireyin yaşamına olumlu etki edebilmesi
için sadece okuduğunu anlamayla sınırlı kalmaması, daha işlevsel bir araç olacak şekilde geliştirilmesi gerekir. Bu çalışmada, uzaktan eğitim sürecinde kullanılan Eğitim Bilişim Ağı’nda (EBA) okuma becerisine ilişkin öğretmen görüşleri
alınarak okuma becerisinin yeterlilik düzeyi tespit edilmeye çalışılmıştır. Araştırmada nitel araştırma desenlerinden birisi olan durum çalışması kullanılmıştır. Araştırmanın çalışma grubunu Milli Eğitim Bakanlığında çalışan 40
Türkçe öğretmeni oluşturmaktadır. Araştırmada yarı yapılandırılmış görüşme formu kullanılmıştır. Veriler “Uzaktan Eğitim Sürecinde Kullanılan EBA’da Yer Alan Okuma Becerisine İlişkin Öğretmen Görüşme Formu” ile toplanmıştır. Verilerin
çözümlenmesinde içerik analizi kullanılmıştır. Bulgulardan elde edilen sonuçlara göre uzaktan eğitim yapılan EBA'da okuma becerisine yönelik öğretmen görüşleri olumsuz yöndedir. Karşılıklı etkileşimin olmaması, teknolojik yetersizlikler
gibi etkenlerden dolayı öğretmenler EBA’yı okuma becerisi açısından dezavantajlı bulmuşlardır. Araştırmaya katılan öğretmenlerden faydalı bulanlar çabaların iyi olduğu ve başarılı olduğu yönünde yorumlar yapmışlardır. EBA’da okuma
becerisi açısından teknolojik yetersizlikler giderilirse, karşılıklı etkileşim geliştirilirse ve okuma etkinliklerine gösterilen önem artarsa öğretmen görüşleri olumlu şekilde olabilir.

Published: September 2020

Foreign language education is not limited to grammar teaching. Listening, speaking, reading and writing skills should be included equally together with vocabulary and grammar teaching in order to achieve effective and meaningful learning.
In countries such as Turkey, the effect of selection examinations dominates the elements in curriculum. Skills such as reading and writing become priority but still, expected achievement cannot be reached. It is seen that English
scores are low in selection exams to secondary education. The aim of the study is determined as to examine secondary school English teachers’ opinions on materials related to reading skills in public coursebooks. Also another aim
of this study is to reveal teachers’ opinions on students’ efficiency in reading. The research was designed according to the phenomenology pattern, which is one of the qualitative approaches. Participants consisted of 20 English
teachers working in private and public schools at the secondary school level in İstanbul. The study group was selected in accordance with the homogenous sampling. The data were obtained through interviews with semi-structured interview
questions. The data obtained were analyzed in accordance with the content analysis. As a result, it was revealed that the teachers thought that the materials are not sufficient in terms of reading skills and the reading passages
in coursebooks were not authentic, interesting or compatible with grammar subject. They stated that the passages were mostly too easy and too short. The participants stated that students were not aware of the importance of the
reading skill and that they are not efficient in reading.
Using Classroom Debates to Develop Efl Students’ Pragmatic Competence and Critical Thinking
Authors: Nuredeen Waleed
Published: September 2020

In a learning environment where university students study EFL in large classes with relatively few opportunities for communication, and where students’ learning history tends to emphasize memorization and direct recall of knowledge,
classroom debates can provide a vehicle for improving students’ listening and speaking skills, developing important aspects of their pragmatic competence and enhancing their critical thinking skills. Though rewarding, the use of
classroom debates can be challenging to both teachers and students. Choosing a suitable format for the debate, familiarizing students with this format, guaranteeing students’ interest in and knowledge about the topic of debate,
getting all the students involved in the debate and managing classroom during the debate are only some of the concerns for which a teacher needs to plan. This article offers suggestions for handling all the concerns related to
the use of classroom debates. Aiming to optimize the use of debates, the article concludes with presenting a number of proposed techniques for their use in the classroom. Through these techniques, teaching functional language and
critical thinking are interwoven to develop students’ both pragmatic competence and critical thinking skills simultaneously.
