Gondolatok az intézkedéstaktikáról
Authors: Mátés Gábor
Published: May 2020

Police tactics is a very important but neglected topic. There are just a few written documents about it, there is no schoolbook with comprehensive information about it, that’s why the education of police tactics is at low level. It’s probably related to the knowledge of the Hungarian police officers, which is not so perfect, I think. We need to collect all the knowledge we have about police tactics; we need to update it, we need to look for new information, and then we need to educate it at a higher level. My first step is determination of the concept police tactics.

Does corporate governance structure matter for firm financial performance? A system GMM panel analysis for Vietnam
Authors: Pham Duc Anh , Hoang Thi Phuong Anh
Published: May 2020

This paper investigates the impact of governance characteristics on financial performance of companies listed on the Ho Chi Minh Stock Exchange. By employing the system generalized method of moments estimator and a panel dataset covering 152 firms over the period from 2011 to 2016, our results indicate that corporate governance characteristics namely the size of board and block-holder ownership, affect the financial performance of Vietnamese firms. Surprisingly, no statistically significant evidence is found concerning the impact of other characteristics such as board gender diversity, CEO duality and non-executive director representation on firm performance.
The effects of cash in advance on export decision: the case of Vietnam
Authors: Doan Ngoc Thang , Nguyen Kieu Trang , Mai Phu Cuong
Published: May 2020

This paper investigates the effect of cash in advance (CIA) on the export decision in Vietnamese firms in the face of financial and institutional constraints. We find that the CIA has a positive relationship with the probability of export in the institutionally constrained firms, and this effect becomes pronounced when those firms are small and medium-sized or also suffer financial constraints. This finding suggests that the CIA does help firms export by mitigating the joint effects of constraints imposed on Vietnamese small and medium-sized enterprises (SMEs).
Oil price and firm profitability: evidence from Vietnamese stock market
Authors: Tran Quoc Trung , Vo Thi Thien Trang
Published: May 2020

Although many prior studies show that oil price affects negatively macroeconomic environment and stock prices, there are few studies on the impact of oil price on firm profitability. This paper posits that oil price tends to affect firm profitability negatively via increases in production costs and negative changes in the macroeconomic environment. As a transition economy, Vietnam has been gradually integrated into the world economy and affected by international economic shocks. Therefore, Vietnam is a potential laboratory to investigate the effect of oil price as an exogenous factor on firm profitability. Using a sample of 6,960 observations from 951 firms listed in Ho Chi Minh City Stock Exchange (HOSE) and Hanoi Stock Exchange (HNX) between 2005 and 2016, we find supporting evidence for the negative impact of oil price on firm profitability.
LINGUISTIC ASPECTS AS CREATIVITY EXPRESSION IN COMPUTER-MEDIATED BUSINESS COMMUNICATION
Authors: Darginavičienė Irena , Suchanova Jelena
Published: May 2020

Business communication online has developed over time due to the constant change of modern communication technologies. Researchers affirm that digital technologies have both positive and negative impact on business communication. Creativity in business communication turns to be crucial in the realization of business opportunities. However, it is linked not only to imagination or original ideas. It also means innovation and innovativeness, the use of innovative digital technologies that help to fuel great ideas, enhance critical thinking, open new ways to business ambitions. The study is devoted to the analysis of linguistic aspects in computer-mediated business communication. Two types of digital business discourse – e-mail and websites of insurance companies – are analyzed with the focus on their linguistic features. From the linguistic point of view computer-mediated business communication differs from conventional business communication and the use of lexicon (e.g. special formal and standard vocabulary) is critical in making this communication successful. Grammatical features of business language are also of great relevance. Stylistic features employed in business communication are also crucial since they help to provide emphasis, achieve clarity and freshness of expression. Linguistic elements of computer-mediated communication in e-mails and analysed websites do not always coincide. The analysis has shown that websites tend to be less formal and compared to e-mails are more exposed to creative linguistic expressions.
DEVELOPMENT OF A REVISED TAXONOMIC APPROACH FOR IMPROVING SUPPLY CHAIN INTEGRATION AND COLLABORATION
Authors: Chen Ping-Kuo , Lu Yun Yan
Published: May 2020

Although integration and collaboration are considered critical factors in supply chain practice,
improving integration and collaboration still encounters a dilemma that is ascribable to three problems, i.e., partners’
opportunistic behaviours, the complicated resource distribution and heavy workloads, and large time costs. To solve these
problems and effectively improve integration and collaboration, a revised taxonomic approach will be developed in this
research. Based on the case of East Asia, the revised taxonomic approach can produce guidelines to help manufacturers
well know how to effectively improve integration and collaboration in a sequential manner and avoid encountering the three
problems noted above. There are multiple implications of this study; the research results not only develop a new approach
by revising theory but also provide convenient tools to help manufacturers effectively improve integration and collaboration
when entering different markets. Thus, this study makes great contributions to the field.
UNDERSTANDING THE STRUCTURAL BEHAVIOR OF HISTORICAL BUILDINGS THROUGH ITS CONSTRUCTIVE PHASE EVOLUTION USING H-BIM WORKFLOW
Authors: Calì Alfredo , Dias de Moraes Poliana , Do Valle Ângela
Published: May 2020

Knowledge is fundamental to understand the key characteristics of a heritage building.
Furthermore, constructive analysis of a historical construction is central to research into its structural
behavior. This work aims to increase the knowledge level of a historical construction by the understanding of
the constructive evolution through Historical-Building Information Modeling (H-BIM) workflow. The research
proposes a multidisciplinary approach applicable to the field of historical constructions, which is resumed
in the followings steps: historical-critical analysis, material and soil characterization, data organization
through H-BIM, qualitative static and dynamic structural analysis, validation of the results. The building of
Quartel da Tropa – located in Florianópolis, Brazil – is used as a practical case study to show how the proposed
research can be adapted to historical buildings. Such an impressive eighteen-century masonry construction is
the largest troop barracks among Brazilian fortifications. The proposed approach allows the creation of
a structural model from the architectural model with fewer uncertainties and less simplification, improving
the knowledge path of historical constructions and its structural assessment. The historical-critical analysis
and the H-BIM allow managing and presenting of the information useful to the understanding of the constructive
phase evolution of a historical building.
EVALUATING THE SAFETY PERFORMANCE OF CHINA’S PROVINCIAL CONSTRUCTION INDUSTRIES FROM 2009 TO 2017
Authors: Kang Liangguo , Wu Chao
Published: May 2020

Performance evaluation in construction safety is of great importance to further improve upon safety
management processes. This paper develops a data envelopment analysis (DEA) based framework to evaluate the construction
safety performance at the macro level. The core of the method is to compare the output-input ratio of construction safety.
Using the building practitioner, construction machinery and equipment, and construction area as the inputs, and value added
of construction and death toll as the outputs, safety performance score is computed for the China’s provincial construction
industries from 2009 to 2017. The results show that the number of benchmark provinces every year is between five and seven.
The gap between the best-performing and underperforming province was relatively small in 2012 and big in 2014. Beijing,
Qinghai, Hainan, Fujian, Chongqing, and Tianjin can be utilized as role models for the provinces that need to improve their
performance in construction safety. The eastern region has the highest score in construction safety performance, followed by
the western and central region. This study provides an effective solution to solve performance issue in regional construction
safety and improves the tradition performance evaluation system to a certain extent.
A DATA-DRIVEN MADM MODEL FOR PERSONNEL SELECTION AND IMPROVEMENT
Authors: Chuang Yen-Ching , Hu Shu-Kung , Liou James J.H. , Tzeng Gwo-Hshiung
Published: May 2020

Personnel selection and human resource improvement are characteristically multiple-attribute
decision-making (MADM) problems. Previously developed MADM models have principally depended on experts’ judgements
as input for the derivation of solutions. However, the subjectivity of the experts’ experience can have a negative
influence on this type of decision-making process. With the arrival of today’s data-based decision-making environment,
we develop a data-driven MADM model, which integrates machine learning and MADM methods, to help managers select
personnel more objectively and to support their competency improvement. First, RST, a machining learning tool,
is applied to obtain the initial influential significance-relation matrix from real assessment data. Subsequently,
the DANP method is used to derive an influential significance-network relation map and influential weights from
the initial matrix. Finally, the PROMETHEE-AS method is applied to assess the gap between the aspiration and current
levels for every candidate. An example was carried out using performance data with evaluation attributes obtained
from the human resource department of a Chinese food company. The results revealed that the data-driven MADM model
could enable human resource managers to resolve the issues of personnel selection and improvement simultaneously,
and can actually be applied in the era of big data analytics in the future.
Universal Transition Diagram from Dormant to Actively Accreting Supermassive Black Holes
Authors: Inayoshi Kohei , Ichikawa Kohei , Ho Luis C.
Published: May 2020

The vast majority of supermassive black holes (SMBHs) in the local universe exhibit levels of activity much lower than those expected from gas supplying rates onto the galactic nuclei, and only a small fraction of silent SMBHs can turn into active galactic nuclei. Revisiting observational data of very nearby SMBHs whose gravitational spheres of influence are spatially reached by the Chandra X-ray satellite, we find that the level of BH activity drastically increases from the quiescent phase when the inflow rate outside of the BH influence radius is higher than 0.1% of the Eddington accretion rate. We also show that the relation between the nuclear luminosity and gas accretion rate from the BH influence radius measured from X-ray observations is well described by the universal state transition of accreting SMBHs, as predicted by recent hydrodynamical simulations with radiative cooling and BH feedback. After the state transition, young massive stars should form naturally in the nucleus, as observed in the case of the nearest SMBH, Sagittarius A*, which is currently quiescent but was recently active.
Periodic Fast Radio Bursts as a Probe of Extragalactic Asteroid Belts
Authors: Dai Z. G. , Zhong S. Q.
Published: May 2020

The periodic activity of the repeating fast radio burst (FRB) 180916.J0158+65 was recently reported by the CHIME/FRB Collaboration team. From this source 28 bursts not only show a ∼16 day period with an active phase of ∼4.0 days, but they also exhibit a broken power law in differential energy distribution. In this Letter, we suggest that FRB 180916.J0158+65-like periodic FRBs could provide a unique probe of extragalactic asteroid belts (EABs), based on our previously proposed pulsar-EAB impact model, in which repeating FRBs arise from an old-aged, slowly spinning, moderately magnetized pulsar traveling through an EAB around another stellar-mass object. These two objects form a binary, and thus the observed period is in fact the orbital period. We show that this model can be used to well interpret all of the observed data of FRB 180916.J0158+65. Furthermore, we constrain the EAB’s physical properties and find that (1) the outer radius of the EAB is at least an order of magnitude smaller than that of its analog in the solar system, (2) the differential size distribution of the EAB’s asteroids at small diameters (large diameters) is shallower (steeper) than that of solar system small objects, and (3) the two belts have a comparable mass.

Published: May 2020

Studies on the bivalve family Sphaeriidae in North Africa are very limited at the surface water level, but even more for caves. During an expedition in 2019 to the Ait M’hamed cave (Oum Er Rabia Basin), six specimens of the genus Pisidium were collected. Morphometric and genetic analyses showed that these individuals belong to the species Pisidium subtruncatum Malm, 1855. This work is the first step towards future exploration of cave Sphaeriidae in North Africa.

Authors: Stamatis Pavlos , Turkiewicz Aleksandra , Englund Martin , Jönsson Göran , Nilsson Jan-Åke , Turesson Carl , Mohammad Aladdin J
Published: May 2020

Objective.

To investigate the association between infections and the subsequent development of giant cell arteritis (GCA) in a large population-based cohort from a defined geographic area in Sweden.

Methods.

Patients diagnosed with biopsy-confirmed GCA between 2000 and 2016 were identified through the database of the Department of Pathology in Skåne, the southernmost region of Sweden. For each GCA case, 10 controls matched for age, sex, and area of residence were randomly selected from the general population. Using the Skåne Healthcare Register, we identified all infection events prior to patients’ date of GCA diagnosis and controls’ index date. With infection as exposure, a conditional logistic regression model was employed to estimate the OR for developing GCA. The types of infections contracted nearest in time to the GCA diagnosis/index date were identified.

Results.

A total of 1005 patients with biopsy-confirmed GCA (71% female) and 10,050 controls were included in the analysis. Infections were more common among patients subsequently diagnosed with GCA compared to controls (51% vs 41%, OR 1.78, 95% CI 1.53–2.07). Acute upper respiratory tract infection (OR 1.77, 95% CI 1.47–2.14), influenza and pneumonia (OR 1.72, 95 % CI 1.35–2.19), and unspecified infections (OR 5.35, 95 % CI 3.46–8.28) were associated with GCA. Neither skin nor gastrointestinal infections showed a correlation.

Conclusion.

Infections, especially those of the respiratory tract, were associated with subsequent development of biopsy-confirmed GCA. Our findings support the hypothesis that a range of infections may trigger GCA.
Éduquer les jeunes délinquants en centre pénal : des motifs de placement au cœur de dynamiques complexes
Authors: Sanzane Jean , Bodin Dominique
Published: May 2020

Alors que la recherche d’un climat social apaisé constitue en France un enjeu majeur pour l’accueil, l’éducation et/ou la rééducation des jeunes accueillis en Centre éducatif fermé (CEF), Centre éducatif renforcé (CER) ou Centre de placement immédiat (CPI), la démarche qui consiste à accueillir, au sein d’un même établissement des personnes aux profils divers et variés (âges, antécédents, raisons de placement) est loin de permettre d’instaurer un tel environnement de travail. Pis encore, cette pratique, portée par des idéaux éducatifs et ré-intégratifs, finit par favoriser l’émergence de conflits, creuset de dynamiques identitaires tant individuelles que collectives. Au sein de ces établissements, se construisent et se donnent à voir des jeux d’acteurs liant parfois, opposant certaines fois, contraignant toujours l’ensemble des protagonistes, quels qu’ils soient (jeunes, éducateurs, etc.). Et si la prise en charge individualisée est très souvent privilégiée comme focale d’analyse, cet article se propose de montrer qu’elle est court-circuitée par des dynamiques identitaires entre pairs ou groupes de pairs ou des jeux d’acteurs qui incluent les encadrants eux-mêmes. Mené sur la base de récits de vie, il entend éclairer comment dans les pratiques, se construit le traitement éducatif de la délinquance des mineurs dans ces centres.
Vomiting Children: It's Not Always Gastroenteritis
Authors: Mier Madeline , Nelson Amanda , Finkel Leah
Published: May 2020

Emesis is a common presentation in children. Many diagnostic considerations need to be made in a child with emesis and no diarrhea, particularly if lasting longer than 24 hours. The differential diagnosis includes trauma, increased intracranial pressure, obstruction, and metabolic abnormalities such as diabetic ketoacidosis. Prompt recognition with appropriate testing and management is needed.

Medical Anthropology in Pediatrics: Improving Disparities by Partnering with Families
Authors: Mandlik Nandini , Kamat Deepak
Published: May 2020

Cultural health beliefs and practices often affect accuracy of diagnoses, health care delivery, and treatment plan adherence, which can lead to health disparity. However, the effect of these belief systems, and acceptance of health care provider recommendations is not commonly discussed. As the proportion of patients from a variety of ethnic and cultural backgrounds increases, an awareness of these belief systems can help achieve better health outcomes. A provider who is flexible and can understand and possibly integrate traditionally non-Western approaches into their treatment plans may build a stronger bond of trust with their patient, thus building a bridge to better health and well-being.

Published: May 2020

The Illinois Chapter, American Academy of Pediatrics Refugee Immigrant Child Health Initiative (RICHI), a collaboration of physicians and child advocates, is one of the most robust state chapter programs of its kind. RICHI evolved by tapping into its key demographics to discern both patient needs and providers' skill sets. Although both may be unique to Illinois and its provider base, they can nonetheless provide a framework for creating and guiding state chapters to support the special needs of children in immigrant families. This article illustrates the importance of identifying and analyzing relevant local demographic and policy-related concerns and how to build capacity, connect to local resources, and form key partnerships.

Published: May 2020

This study explores public perceptions toward online learning application in Indonesia. Many studies about online learning were done in developed countries and only a few in developing countries. Moreover, these studies used a qualitative approach which limits the results to be applied in different settings. While traditional research using a survey to understand people's perception towards an entity requires a lot of time and efforts; we used efficient and effective manners to gather opinions and then analysed its sentiments using the Logstash, Kibana and Python programming language stack (ELK) stack and Naïve Bayes algorithm. We used Naïve Bayes algorithm for sentiment analysis and ELK stack for storing & gathering tweets from Twitter. With ELK stack, we successfully collected 133.477 tweets related to online learning. From this study, we understood what kind of words that are sentimentally positive and negative tweets. We also gained some insights regarding Indonesia’s student online learning application preferences.
Optical Gamification (OG); Serial Versus Random Model to Improve Pre-Service Physics Teachers’ Concept Mastery
Authors: Saprudin Saprudin , Liliasari Liliasari , Setiawan Andhy , Prihatmanto Ary Setijadi
Published: May 2020

OpticalGamification (OG) is an information and communication technology (ICT)-based gamification-application that applies the elements of game design in a serious context of optics. Through setting for the variations in pre-service physics teachers’ (PPTs) access to the topics presented in this application, two OG application models are generated, namely: 1) serial model; designed to facilitate PPTs who study sequentially, and 2) random models; designed to facilitate PPTs who study randomly depends on their choices. This research is quasi-experimental with pretest posttest nonequivalent multiple group design involving 48 PPTs enrolled in wave and optics course, specifically on the topics of interference and diffraction. The results of this research indicate that there is no significant difference in the improvement of PPTs’ concept mastery in the serial and random group. Both of these models can be used as references in designing ICT-based gamification-applications for a more effective and efficient learning in the future.

Published: May 2020

Technological progress has resulted in constant change of social structures and led to continuous evolution of attitudes and values. Thus, a timely and compre-hensive integrated technology acceptance framework was established, and factors predicting intention to use Cloud e-learning were empirically identified. A total of 11 determinants from varying sources of IS success, learning object criteria, technology acceptance, motivations, social cognitive, and expectancy values were unified and analysed in an integrated manner. The target population for this study was a group of IT students in a private university in southern region Malaysia. The results obtained from this study observed that content quality, pedagogical quality, perceived usefulness, social influence, attainment value, and utility value significantly predict intention to use Cloud e-learning. By integrating IS success, learning object criteria, technology acceptance, motivations, social cognitive, and expectancy values into a single framework, new insights on Cloud e-learning ac-ceptance in higher education can be attained.

Misconceptions take place in a variety of Physics lesson subjects including the Light and Optics. This study aimed at determining the students’ misconceptions and the effectiveness of Active Learning of Optics and Photonics (ALOP) approach assisted by computer simulation to reduce misconceptions among students on the material of optical instruments. The mixed method was employed in this study using embedded mixed method design. The study was conducted to students of grade XI in one senior high school in Bandung. The participants were divided into two groups: control group and experimental group in which each group consisted of 23 students. A conventional learning was applied in the con-trol group while the experimental class implemented ALOP computer-aided simulation learning. The instrument used to identify students’ misconceptions were Four-Tier Optics and Photonics Test (FTOPT), consisted of 18 items, which was given during the pre-test and post-test. The results showed that misconceptions were disseminated over the concept of eyes, camera, magnifier, mi-croscopes, and telescopes. Additionally, ALOP approach using computer-aided simulations is effective to reduce students’ misconceptions on the material of op-tical instrument.
Use of Critical Annotation and Interactive Fiction for the Creation of Digital Educational Content
Authors: Diez-Sanmartín Covadonga , Gayoso-Cabada Joaquín , Sarasa-Cabezuelo Antonio
Published: May 2020

Interactive fiction and critical annotation are two very important activities in the field of philology teaching. The first activity aims to turn the reader into an ac-tive element in reading electronic books. For this, different gadgets and tech-niques are used that force the reader to have to make decisions in the reading process. With respect of the annotation, it is an activity that aims to enrich liter-ary texts with meta-information that allows explaining or extending the infor-mation that appears in the contents of a book. Both activities are fundamental in the training of philology students. In general, there are few specific electronic publishing tools for these activities, and those that exist have a professional ori-entation. In this article, two tools are described that have implemented the func-tionality necessary to carry out these activities but with an academic orientation. In this way, students can learn both activities in a friendly, intuitive environ-ment designed for education.

Authors: Sabry Sana Sabah , Sahib Mouayad , Nayl Thaker
Published: May 2020

Cerebral Palsy (CP)is a collection of permanent, non-progressive disorders that impact the individual’s motor ability. The rehabilitation of patients with CP is very important to improve their motor abilities and to minimize the need for third parties. In this paper, a low-cost hand rehabilitation glove based on finger bend/pressure analysis is presented. The data glove is used to improve hand functioning for pre-school children with cerebral palsy through virtual reality games. The system consists of two parts: the data glove and several virtual games. The data glove consists of a microcontrol-ler, flex sensors, force sensors and radiofrequency transmission units. The use of the newly developed system will assist psychotherapist to follow the CP child daily, weekly or monthly. The rehabilitation model and the predicted physiotherapy results can be extracted from the patient’s record after using the data. Experimental results have shown that the regular usage for the data glove improved 75 % of the participants’ fingers bending angel and the child’s grip ability.
Analysis on Influencing Factors of Dance Teaching Effect in Colleges Based on Data Analysis and Decision Tree Model
Authors: Guo Beibei
Published: May 2020

In colleges, dance teaching is influenced by a variety of factors. It is very difficult to clarify how much each factor impacts the teaching effect. To overcome the difficulty, this paper explores the factors affecting the dance teaching effect in colleges based on data analysis and decision tree model. Firstly, the authors enumerated the goals of dance teaching for college students in the new era, and then summed up the constraints on the influencing factors of dance teaching effect in colleges. On this basis, an analysis model was established for the influencing factors, while the corresponding extensible decision tree was set up and verified through example analysis. The research findings shed new light on the theories of dance teaching in colleges, and provide an analysis model with great application potential.
Early Intervention versus Standard of Care for Mild Idiopathic Scoliosis: A Case-Controlled Series Based on Sosort Criteria Evaluating the Impact of a Scoliosis Activity Suit
Authors: Morningstar Mark
Published: May 2020

In the present study, a group of adolescent patients diagnosed with mild adolescent idiopathic scoliosis wore a scoliosis activity suit instead of maintaining the recommended observation only strategy. These patients wore the scoliosis activity suit for up to 60 minutes twice daily while performing normal daily activities. These patients were followed through until end of growth. Their end of growth results were compared to a group of adolescent idiopathic scoliosis (AIS) patients who only participated in observation. The group who wore the scoliosis activity suit maintained their curve measurements through skeletal maturity, while the observation group saw their curves increase an average of 7 degrees. This study showed that a group of AIS patients were able to prevent their curves from progressing during growth, while those participating in an observation-only strategy saw their curves progress to beyond threshold where rigid brace prescription is recommended. These changes were statistically significant in intergroup comparison, as well as intragroup before and after comparison.

Published: May 2020

Anaplastic lymphoma kinase (ALK)- negative anaplastic large cell lymphoma (ALCL) is an aggressive CD30-positive non- Hodgkin lymphoma. ALK-ALCL rarely manifests with extensive bone marrow and peripheral blood involvement (known as “leukemic phase”). A 54-year-old woman was diagnosed with ALK-ALCL in leukemic phase, characterized by an extremely poor prognosis. Lymphoma cells in this case showed chromosomal translocation 1p36.1- encoded RUNX3 and overexpression of its protein. She was refractory to CHOP and salvage chemotherapy. Fortunately, she achieved complete remission with three cycles of Brentuximab vedotin (BV) and underwent umbilical cord blood transplantation. However, she died due to treatment-related mortality on day 129. The autopsy findings showed no lymphoma cells. Treatment strategy for ALK-ALCL is controversial, but the efficacy of BV in CD30-positive peripheral T-cell lymphoma not only as salvage regimens, but also in first line, has been reported in recent years. BV may be an effective option for ALK-ALCL in leukemic phase.
Atrazine removal in aqueous solutions using activated carbon from peach stone
Authors: Pruchniak Ana Paula Staben , Silva Graziella Dos Santos Portes , Lima Liliane Schier de , Quináia Sueli Pércio
Published: May 2020

Activated carbon is commonly used as a material for contaminant-adsorption processes in aqueous systems. However, its use is more restricted to charcoal than to coal, for the most part, in view of the fact of the higher cost (~ 40%) if the mineral is a fossil fuel which needs to be extracted from the earth by mining. For this reason, the peach stone that comes from alimentary industrial tailings can be a good choice for the separation of pollutants from aqueous suspensions and other soluble substances. The purpose of this research was the development of a low-cost filter, using stones to remove atrazine from water. Appraisal and characterization studies were performed along with batch experiments to investigate dosing effects of the activated carbon, atrazine concentration, contact time, and adsorption pH on removal procedures. From the results of the experiment, an excellent removal of the analyte in question was observed under conditions that can be considered as close as possible to the environment, such as pH = 6.5, room temperature and 10 minutes of agitation time, always choosing the best alternative with the lowest cost of energy and time. Batch system application has been recommended as versatile for utilization in seasonal problems such as pesticide contamination.

Rendement scolaire et fonctionnement exécutif chez les jeunes ayant un TDA/H : le contexte de la transition primaire-secondaire
Authors: Parent Véronique , Vaudeville Isabelle
Published: May 2020

Cette étude évalue l’impact de la transition de l’école primaire à l’école secondaire sur le rendement scolaire et le fonctionnement exécutif des jeunes présentant un trouble de déficit de l’attention/hyperactivité (TDA/H). Vingt-sept jeunes (avec ou sans TDA/H) et leurs parents ont participé à l’étude. Le fonctionnement exécutif a été mesuré par un questionnaire (BRIEF; versions parent et auto-rapportée). Le rendement scolaire a été mesuré 1) de manière formelle (WIAT-II) et 2) selon les enseignants (échelle de rendement scolaire). Les mesures ont été effectuées à deux reprises, en sixième année et en première secondaire. Les résultats montrent, globalement, un rendement scolaire et un fonctionnement exécutif évalué par les parents inférieurs pour les jeunes présentant un TDA/H. Seule la flexibilité cognitive semble diminuée par le contexte de transition. Certains indicateurs soutiennent également un effet délétère de la transition sur le rendement scolaire pour tous les jeunes. L’étude souligne l’importance de soutenir les jeunes, particulièrement ceux avec un TDA/H, lors de cette période charnière.
Validité du test des 48 images dans la détection de la simulation des troubles de la mémoire : données de références
Authors: Rouleau Isabelle , Mallette Pierre-Luc
Published: May 2020

La simulation et l’exagération des troubles cognitifs doivent être envisagées dans l’interprétation du profil neuropsychologique surtout lors d’expertises. À cette fin, la validité du test des 48 images (48-I) a été examinée en comparant la performance de 55 simulateurs présumés à celle de 37 simulateurs volontaires et à celle de 389 patients, dont 22 amnésiques et 105 présentant une atteinte légère à modérée de la mémoire. Tous ont complété l’épreuve des 15 mots de Rey et le rappel immédiat de la figure complexe de Rey. Aucune différence n’a été observée entre les deux groupes de simulateurs. Au 48-I, le score obtenu par les simulateurs est aussi faible que celui des amnésiques, mais ils réussissent aussi bien les autres tests de mémoire que les patients avec atteinte mnésique légère à modérée, qui eux obtiennent une performance presque parfaite au 48-I. Ces résultats supportent la validité du 48-I dans la détection de la simulation.
Third Graders’ Identities as “Persons Who Understand Nature of Science” through an Electricity Unit
Authors: Kaynak Naime Elcan , Akerson Valarie L. , Cevik Emel
Published: May 2020

The purpose of this study is to explore third grade elementary students’ Nature of Science (NOS) identities as a result of participating in a unit on electricity. The study took place in the context of a diverse third grade “at risk” (as identified by state regulations) classroom. Videotapes were made of all aspects of the electricity lessons, including pre-lesson class discussions, activities engaged in by students, and follow-up class discussions at the conclusion of each lesson. Findings revealed that third graders began to develop identities of persons who conceptualize NOS. Even though through one unit they did not address all aspects of NOS, they showed great development in their identities for young third grade students.
Faculty Engagement in Internationalization: The Role of Personal Agency Beliefs
Authors: Nyangau Josiah Zachary
Published: May 2020

As higher education in the United States has experienced a proliferation of internationalization activities, there has been a steady stream of studies directed at understanding institutional rationales for internationalization.  Further, an emerging body of research seeks to understand faculty motivations of international involvement.  However, scant attention has been devoted to understanding the role of personal agency beliefs in facilitating faculty international engagement.  This study, part of a larger project, draws on in-depth interviews with fifteen faculty to address this topic.  The findings show that strong efficacy beliefs and positive perceptions about organizational context are strong influences on faculty behavior relative to international engagement.
A Multistep Inquiry Approach to Improve Pre-Service Elementary Teachers’ Conceptual Understanding
Authors: Mataka Lloyd M. , Taibu Rex
Published: May 2020

A quasi-experimental control group pre- and post-test study was used to determine the effect of a Multi-Step Inquiry (MSI) approach on pre-service elementary school teacher’s conceptual understanding. The MSI study involved the development of a conceptual workbook, and a Physical Science Concept Inventory. The conceptual workbook has activities that explicitly target students’ misconceptions in physical science. The inventory has three categories: forces and motion, heat and temperature, and electricity. Descriptive and inferential statistics were used to interpret the data. Independent t-tests were used to compare the experimental and comparison groups. Further, Cohen’s d and Hake’s g effect sizes were used to determine the effectiveness of MSI. Results indicated that the MSI approach as an effective teaching strategy for conceptual understanding. As such, the authors have made recommendations for both research and teaching.
The Effects of Blended Learning on STEM Achievement of Elementary School Students
Authors: Seage Steven J. , Türegün Mehmet
Published: May 2020

Science, technology, engineering, and mathematics (STEM) programs serving students from low socioeconomic areas are understudied in the literature. More research studies need to be conducted to make informed instructional decisions for students who may be at a disadvantage compared to their peers from higher socioeconomic areas. The purpose of this research study was to determine the effects of traditional science instruction and blended learning on STEM achievement of elementary school students from low socioeconomic areas. Third, fourth and fifth grade students (N = 129) from a low-socioeconomic school were randomly assigned to receive traditional science instruction or a blended learning science curriculum approach. The science, technology, engineering, and mathematics (STEM) achievement scores were analyzed by conducting a one-way two-group Multiple Analysis of Variance (MANOVA) implemented in R statistical computing platform (R Core Team, 2018). The results indicated that the teaching method had a statistically significant effect on the linear combination of the science, technology, mathematics and engineering scores (F(4,124) = 80.27, p < .0001, Pillai’s Trace = .721, partial η2 = .721), in favor of the blended learning approach.
Secondary School Students’ Initial and Changes in Cognitive Structures of Argument and Related Concepts
Authors: Yildirir Hasene Esra
Published: May 2020

The purpose of this study was to determine the state of secondary school students’ cognitive structures about argument and related concepts and to reveal the change in their cognitive structures regarding these concepts after the implementation of the argumentation-oriented approach in science lessons. This study was conducted in Grade 6, 7, 8 classes, including a total of 80 students. This study follows a pre-experimental one group pretest–posttest design. Students were administered a word association test (WAT) covering argument and related concepts prior to and following the lessons. The results obtained from the WAT show that the students’ cognitive structures progressed from the pretest to posttest, with an increase in the number of response words and connections between words, and with a change in the nature of these connections. As a result of teaching science lessons through argumentation, it was detected that cognitive structures of students regarding argument and related concepts indicated changes in the right way.
Competence of Faculty, Staff, and Administrators in Hispanic Culture: Evidence from Three Surveys of Personnel and Students at Hispanic-Serving Institutions
Authors: Preuss Michael , Sosa Eric , Rodin Jason , Ramos Jorje , Dorsett Christine , Burleson Chenoa
Published: May 2020

Survey data were gathered from college and university faculty, staff, and administrators at Hispanic-Serving Institutions (HSI) regarding Hispanic culture and Hispanic students as part of an NSF-funded investigation that focused on the characteristics and programming of HSIs as well as the background and experiences of their students. Two surveys of students were also conducted. A minimum of 44 HSIs in Texas, New Mexico, and Colorado were represented in the 393 usable responses gathered from faculty, staff, and administrators. Fourteen HSIs in New Mexico and Texas were represented in student survey data gathered in 2018 and three in north Texas in a survey completed in 2019. Responses from 213 Hispanic students were isolated from the 2018 student survey and 307 from the 2019 data. This material was used to verify and expand on the findings from the survey of faculty, staff, and administrators. A consistent and strong difference of opinion was found between Hispanic faculty, staff, and administrators at the HSIs and their non-Hispanic peers regarding information available to higher education professionals about Hispanic culture, the elements of Hispanic culture, and the characteristics and background of Hispanic students. Survey responses of Hispanic students confirmed, at many points, that the perspective of the Hispanic faculty, staff, and administrators was accurate. It appears, based on this information, that the non-Hispanic employees at the HSIs were less well informed about Hispanic culture and a major portion of their student population than would be desirable. The findings, while from the south-central United States, can inform multiple academic and support services at Hispanic-Serving Institutions and other colleges and universities as they include information about how Hispanic culture is understood by Hispanics, detail gaps in competence regarding Hispanic culture among faculty, staff, and administrators at HSIs, and describe characteristics and the cultural orientation of Hispanic students attending the HSIs in the sample.

Perspectivas descoloniales en el Chiapas actual: Juan López y Votan Zapata como referentes rebeldes epistemológicos desde el sur
Authors: Ávila Romero Agustín , Sulvarán López José Luis
Published: May 2020

A impressionante rebelião de 1712 no Chiapas colonial sobrevive na memória coletiva das comunidades Mayastzeltal do México. Através da tradição oral, pessoas de diferentes comunidades estão ligadas à história do século XVIII e narram os feitos extraordinários do chefe militar de Bachajon: Juan López Saraos, na revolta indígena contra o domínio espanhol. Quase no final do século XX, no surgimento do Exército Zapatista de Libertação Nacional (EZLN), aparece a história do velho Antonio e dos deuses Votan e Ikal como guardiões dos povos indígenas e das comunidades zapatistas. Tais narrativas abrem as possibilidades de compreender esses eventos em uma perspectiva epistemológica mais ampla do que a revisão unilateral da historiográfica tradicional que se realizou a partir da academia e da epistemologia dominante. Recuperar esta memória também nos permite compreender a evolução histórica a partir de baixo e os símbolos que são construídos e sobrevivem na memória biocultural e dão causa às torrentes que circulam na região atual de Chiapas.
