Authors: Mirhashemi Amir Hossein , Saffar Shahroudi Atefe , Shahpoorzadeh Keyvan , Habibi Khameneh Niloofar
Published: February 2021

Background. This study compared the force decay pattern of two different orthodontic active tiebacks (ATBs) exposed to five different commercially available mouth rinses. Methods. In this in vitro study, 90 transparent ATBs and 90 gray ATBs were divided into six groups; one was the control group, and the others were exposed to one of these mouth rinses twice a day for 60 seconds: Listerine, chlorhexidine, Orthokin, Persica, and fluoride. The initial force of each ATB was 250 g at a 24-mm extension. The force of ATBs was measured on days 1, 7, 14, and 28 using a digital gauge. Results. The highest percentage of force loss was observed between days 14 and 28 (P<0.05). At the end of the study, the Persica group exhibited the highest force degradation in both ATB types. In the transparent ATBs, it was followed by Orthokin, Listerine, fluoride, chlorhexidine, and control groups, respectively. In the gray ATBs, Orthokin, chlorhexidine, control, Listerine, and fluoride groups exhibited the highest force decay in descending order. In some groups, the differences between transparent and gray ATBs were significant. In the control group, the force of transparent ATB was significantly higher than gray ones on days 7 and 14 but not significantly after four weeks. Conclusion. ATBs’ force degradation could be exacerbated by the use of some mouth rinses. There were some differences between force relaxation patterns of transparent and gray ATBs. The data could be beneficial in choosing appropriate O-rings for making ATBs.

Published: February 2021

Background: Deep eutectic solvents (DESs) exist a wide variety of potential and existing applications. Based on the fact that the choline chloride (ChCl) is a complex B vitamin and widely used as food additive, the choline-based DESs are generically regarded as being harmless and non-toxic. In this regard, the low aqueous solubility of celecoxib (CLX) have been increased by use of DESs as neoteric class of solvents at T = (298.15 to 313.15) K. Methods: DESs were prepared by combination of the ChCl/EG, U and G with the molar ratios: 1:2 and ChCl/MA with 1:1. The shake flask method was used to measure the solubility of CLX in the aqueous DESs solutions at different temperatures. Results: The solubility of the CLX increased with increasing the weight fraction of DESs. The observed solubility data was subjected to evaluate the relative performance of a number of models including Apelblat, Yalkowsky and Jouyban–Acree models for their correlation efficacy. Moreover, the apparent dissolution enthalpy, entropy and Gibbs free energy were obtained from the experimental solubility values. Conclusion: It was found that the solubility data was satisfactorily fitted using the mentioned models at different temperatures. The dissolution process of CLX in the studied solvent mixtures within investigated temperature range was endothermic, and the driving mechanism is the positive entropy.
FORMATION OF PACKINGS WITH THE HELP OF WINDING MACHINE WITH PERIODICAL SPEED BUMP OF THE WINDING-UP ROLLER
Authors: Rudovskiy P. N. , Smirnova S. G.
Published: February 2021

For the formation of a high-quality package of cross winding on machines equipped with winding mechanisms with a frictional drive of the package, it is necessary to include special devices in their composition that provide a change in the speed of the yarn feeder or bobbin according to a periodic law with a cycle duration of at least six periods of the yarn feeder movement. Changing the speed of the bobbin can be provided by slipping it by a controlled amount. The amount of slip is determined by the appropriate selection of the winding shaft acceleration (deceleration) and the pressing force of the bobbin against the winding shaft. A mathematical model has been obtained that describes the change in the difference between the displacements of points on the surface of the bobbin and the winding shaft when the winding shaft is accelerated. It is shown that in this way it is possible to effectively eliminate defects in the winding structure in the form of bundles and ribbons.

AUTOMATED DEVICE FOR DETERMINING THE TANGENTIAL RESISTANCE OF TEXTILE MATERIALS
Authors: Lapshin V. V. , Zamyshlyaeva V. V.
Published: February 2021

This article discusses the problems of evaluating the friction of textile materials, the main characteristic of which is the tangential resistance coefficient. In the absence of a standard for friction and modern devices, the development of new automated devices is topical. To implement the possibility of testing for friction, with the translational movement of touching planes, an automated device based on an upgraded nozzle has been developed for a breaking machine that implements Ederley principle. The device allows one to numerically determine the value of the tangential resistance coefficient of fabric samples. The data received by the device is transmitted to the computer for further processing and presentation to the user in graphical form. At the same time, the process of collecting and processing the received information is automated as much as possible. The developed automated device allows one to optimise the choice of materials taking into account friction.

Authors: Bolobonkina TA , Dementiev AA , Minaeva NV , Smirnova NN
Published: February 2021

Summary. Introduction: A biological factor is the leading occupational hazard for healthcare professionals. Identification of risk factors for novel coronavirus disease 2019 (COVID-19) in ambulance employees and substantiation of measures to prevent the spread of this infection is a modern-day challenge. The purpose of our study was to examine COVID-19 incidence rates in emergency medical services (EMS) workers and to identify occupational risk factors for this infection. Materials and methods: We studied COVID-19 cases among Ryazan ambulance employees in terms of their age, sex, position, and specialty taking into account disease severity and duration for the period from May 1, 2020 to September 1, 2020. Results: We established higher relative risk values and incidence rates of the novel coronavirus infection in EMS workers compared to the population of the city of Ryazan (p < 0.05). In May–August 2020, COVID-19 cases among the ambulance employees and the population of Ryazan, as well as the number of EMS-attended patients with acute respiratory infection followed a similar pattern. The number of COVID-19 cases among the staff of resuscitation crews was significantly higher than that in the general practice and other specialized crews (p < 0.05). We estimated a statistically significant high relative risk of a longer and severer course of the disease among physicians compared with paramedics (RR = 1.333; p < 0.05) and among EMS workers aged 61 or older (RR = 1.286; p < 0.05). Conclusions: Emergency medical services workers have a high occupational risk of COVID-19 in the pandemic. Among them, employees aged 31–35 and resuscitation crewmembers face a higher risk of infection. Elderly employees aged 61–64, medical doctors, and general profile EMS workers are most at risk for a more severe and durable disease course.

Authors: Trukhina GM , Lavrik EP , Ivanova YuV , Kravchenko AG
Published: February 2021

Summary. Introduction: Identification of hygienic determinants of the epidemic process and their inducing factors is an urgent regional problem that ensures a decrease in infectious disease rates in modern conditions. One of the priority tasks of the Russian economy is the development of beach tourism in coastal areas. Medical tourism is gaining more and more popularity in Russia: this direction is one of the most promising and demanded. According to the Ministry of Economic Development, 45 % of Russian tourists prefer beach holidays. Development of a competitive, highly efficient tourist and recreational complex is impossible without a modern approach to assessing safety of recreational water facilities for the population and minimizing risks of adverse health effects of recreational water use in holidaymakers. The anthropogenic factor influences reliability of assessments of the local hygienic and epidemic situation. The establishment of cause-effect relationships between the environment and the disease is the basis for elaborating preventive actions. The objective of our study was to analyze the incidence of acute intestinal infections in the local population of the Black Sea coast of the Tuapsinsky district, Krasnodar Krai, and visitors from other regions of the Russian Federation. Materials and methods: We applied epidemiological and statistical methods of analyzing disease incidence taking into account terrain features, age of patients, and seasons of the year. Laboratory test results were used to confirm the etiology of diseases registered in the district. Results: We established season- and age-specific increase in the incidence of acute intestinal infections among groups of the local population having excluded cases among the visitors. The incidence was noted for a high rate of acute intestinal infections caused by potentially pathogenic bacteria and viruses in coastal areas with a developed resort and spa infrastructure as compared to the mountainous areas. We also observed a recent rising trend in the incidence of viral gastrointestinal infections with rotaviruses accounting for 89.8 % of all cases of acute intestinal infections in 2018. Discussion: Our findings were used to develop appropriate preventive measures and to make managerial decisions on surveillance of the recreational facilities in order to prevent the risk of gastrointestinal infections in the area and to create a safe environment for tourists. Conclusions: In the summer months, acute intestinal infections in the area were induced by potentially pathogenic bacteria and viruses. The majority of cases were registered among holidaymakers while children aged 1-6 years were most at risk for gastrointestinal infections.

Published: February 2021

Summary. Introduction: Comprehensive risk management considering behavioral risk factors is a possible way to minimize adverse health effects of occupational factors. The purpose of the study was assess behavioral risk factors and to develop appropriate measures for preventing occupational diseases in oil refinery operators. Materials and methods: The observation groups included crude oil treatment operators of Ritek LLC in the Volgograd Region located in the subarid climatic zone. The first group consisted of 100 workers under the age of 35 while the second group consisted of 106 workers aged 36-60. Previously published studies were used to substantiate priority occupational risk factors for the operators. To assess lifestyle habits, we conducted a questionnaire-based survey and analyzed data in terms of their statistical significance and real controllability using a multidimensional confirmatory factor analysis. Results: We established that the priority occupational health risks of operators in the climatic conditions of the Volgograd Region included labor severity and intensity (3.1) and hot environment (3.2) posing a high occupational risk of disrupting the thermal state (overheating) of workers. We also identified typical behavioral risk factors, the prevalence and quantitative burden of which was age-specific. In the younger age group, bad habits and poor healthcare activity (reluctance to seek medical advice) generated the highest burdens (943 conditional units each) while in the older age group, major burdens were generated by bad habits and malnutrition (849 and 501 units, respectively). The developed mathematical model proved that a comprehensive health risk management for workers exposed to occupational hazards is feasible by correcting certain behavioral risk factors: a 10 % and 50 % decrease in the burden of bad habits and poor healthcare activity led to a 1.1 and 1.5-fold decrease in the extent of health risk, respectively. Conclusion: The study revealed the most significant behavioral risk factors affecting health of oil refinery operators and substantiated options of the most optimal interaction between the elements of the system reducing the overall risk to human health. Comprehensive health risk management based on optimal interaction of system elements (both occupational and behavioral risk factors) reduces health risks for oil refinery operators.

Published: February 2021

Summary. Introduction: As of today, acute viral upper respiratory tract infections (URTIs) remain the most common diseases in the world and the Russian Federation and one of the most important problems of national health care. The objective of our work was to study the dynamics and intensity of the epidemic process of influenza and other URTIs in the Russian Federation and Rostov Region over a thirty-year period and to establish the main features of the disease incidence in the Rostov Region. Materials and methods: We analyzed data of annual State Reports on Sanitary and Epidemiological Wellbeing of the Population in the Russian Federation and Statistical Form No. 2 on information about infectious and parasitic diseases for the period 1990–2019 and data on the size of population using StatSoft STATISTICA 6.1.478 Russian, Microsoft Excel, and NextGIS QGIS software. Results: We found that in 1990–1999, 2000–2009, and 2010–2019, regional URTI rates tended to decrease in each subsequent decade compared to the previous one. The long-term incidence rate of URTIs in the Rostov Region was 16,099.2 ± (2.045 × 384.2) ‰оо, lower than the Russian average rate of 19,710.3 ± (2.045 × 326.4) (p = 0.05). The amplitude of fluctuations in the incidence was 8,015.4 ‰оо and 7,619.6 ‰оо in the Rostov Region and the Russian Federation, respectively. Until 1997, regional incidence rates were comparable to the national averages but demonstrated an upward trend since the year 2000. We revealed unevenness of the course of the epidemic process related to cyclicity, with an increase in the duration of cycles since 1998. It was determined that the regional incidence of influenza was significantly lower than the national average and had a tendency to decrease. The long-term influenza rate in the Rostov Region was 412.4 ± (2.045 × 131.3) (p = 0.05) or almost three times lower than that in the country 1,553.0 ± (2.045 × 301.2) (p = 0.05). The dynamics of influenza incidence in the Rostov Region also had a cyclical course with a smaller amplitude of fluctuations (3,215.1 ‰оо) than in the Russian Federation (5,164.8 ‰оо). The duration of epidemic cycles in 1990–1998 and 2002–2012 was two years but we noted a three-year cycle in 1999–2001. We established a correlation between influenza and URTI rates and population density in regional cities and various age groups: the highest URTI rates (74.9 %) were registered in children between two to 17 years of age while 52.5 % of influenza cases were adults (aged 18+). Conclusion: The established characteristics of the development of the epidemic process of influenza and URTIs in the Rostov Region prove the necessity of a differentiated approach to organizing and implementing comprehensive preventive measures within optimization of epidemiological surveillance of these diseases, and can also serve as basic criteria for disease prediction.

De la situación problemática al problema científico educacional
Authors: Aguirre Chávez Felipe
Published: February 2021

Los problemas científicos de las investigaciones educacionales emergen del conocimiento del estado actual de desarrollo del tema que se pretende investigar. La primera etapa es el diagnóstico, la aplicación de instrumentos, con fines exploratorios, como las entrevistas, encuestas, observaciones, etc.; donde el investigador, independientemente de su objeto de estudio, desentraña, establece o determina situaciones problemáticas con sus perspectivas de solución. Metafóricamente hablando, toda situación problemática viene con la formulación del problema bajo el brazo; pero configurarlo como problema científico viable, novedoso y pertinente requiere motivación y destrezas específicas de problematización en sus múltiples perspectivas de solución.

En dependencia del enfoque y las habilidades del investigador, existen hasta dos posibilidades básicas: pasar con éxito de la situación problemática a la formulación del problema científico o quedar anclado en el callejón sin salida de la imposibilidad de problematizar; y, por ende, de rezagar la producción de nuevos conocimientos.

Un amigo de Ricardo Palma: Celso Víctor Torres
Authors: Ángeles Caballero César
Published: February 2021

Celso Víctor Torres, “Palma ancashino”, nació en Caraz (Villa San Idelfonso, capital de la Provincia de Huaylas) el 28 de julio de 1860 del matrimonio de Eusebio Torres y Antonia Figueroa. Interesan poco los detalles de su instrucción primaria y secundaria, menos aún su quehacer administrativo; sí vale referimos a la circunstancia que ejerciera la Escribanía del Estado desde 1888, porque, acaso, en el trajinar cotidiano de viejos y empolvados papeles y causas judiciales pudo captar la variable temática de sus Tradiciones caracinas. Tras el diario ejercicio de escribano, a partir de 1903, amplía la frecuencia judicial con el ejercicio de la notaría pública, hasta su fallecimiento acaecido el 12 de noviembre de 1918, a las nueve treinta de la mañana en la propia ciudad de Caraz.

Niveles de narcisismo en educadores y sus efectos en la función tutorial.
Authors: Cerna Dorregaray Orlando
Published: February 2021

La presente investigación desea conocer la relación que existe entre la estructura de personalidad narcisista de los educadores con el desempeño de la función tutorial de los mismos. Es un estudio descriptivo correlacional, donde se describen los niveles de narcisismo en los educadores y se los relaciona con la percepción que los educandos tienen de la acción tutorial que realizan sus profesores tutores. Se evaluó a 172 profesores de los cuales 84 son tutores y a 3 765 estudiantes de secundaria de nueve colegios religiosos del Perú. Un aspecto a destacar del presente estudio es que hay mucha investigación de la tutoría en función del estudiante, pero no así desde la perspectiva de la personalidad del educador, como si la misma fuera negada y no se vinculara con el trabajo educativo. Lo que se buscó en el estudio es demostrar la importancia que tiene la variable personalidad del educador en las acciones tutoriales que los educadores realizan; en especial los niveles de narcisismo de los educadores y cómo estos están relacionados con la percepción de los estudiantes de la acción tutorial individual, grupal y con los padres de familia.

Es un estudio transversal descriptivo y la muestra estuvo conformada por 330 internos varones, de los cuales se pudo validar la información de 279 internos. La edad entre los internos vario desde los 18 a más de 65 años, siendo la edad de mayor prevalencia (31,2%) entre 31 a 40 años, el interno con menor edad tiene 18 años y el de mayor edad fue de 75 años. Se utilizó un cuestionario de opciones múltiples, adaptados para la presente investigación, la cual está dividida en cinco áreas: a) nivel educativo, b) estado civil, c) situación jurídica, d) delito y e) consumo de drogas. Asimismo se utilizó el cuestionario de uso de Drogas (DAST-20),  cuya confiabilidad varía entre un 0,92 a 0,94. También se utilizó el cuestionario de Identificación de Trastornos por consumo de alcohol (AUDIT), cuyo nivel de confiabilidad se situaba por encima de 0,90.  Entre las conclusiones más importantes destacan que las drogas de mayor prevalencia entre de las personas recluidas son el alcohol, tabaco, marihuana, clorhidrato de cocaína y pasta básica de cocaína, siendo estas mismas las de mayor consumo en los últimos 30 días. La edad, el grado de instrucción y el delito influyen significativamente en el consumo de drogas al interior del centro penitenciario.
Role of Education Planning in Promoting Social Sciences in Pakistan
Authors: Sabir Imran , Sharif Abida
Published: February 2021

Social Science disciplines have always been considered the second choice as compared to the hard sciences in the academic institutions of Pakistan. Does this apply to the national education policy as well, where the state intervention is catalytic in setting up the academic choices of the people? This study, by critically reviewing the national education policies and plans, endeavors to address this important question to understand the role of education planning in promoting/demoting social science academic disciplines in Pakistan. Education policy in Pakistan has been predominantly proposed through eight national five-year plans between 1955 and 1998, to primarily focus on increasing the national literacy rate, and promoting hard science education and vocational training. After the creation of Higher Education Commission of Pakistan in 2002, the policy significantly shifted to Higher Education, yet to focus (natural/computer) science, and technology. Social science is at the periphery of the knowledge mission in Pakistan. The paper concludes that even the long-awaited recent quantitative growth of social science disciplines fails to produce significant impact on national education policy that almost unanimously seeks their economic worth, instead of their inherent social value.

Objetivo: Identificar crenças de mulheres primigestas que influenciam na procura por assistência odontológica e adoção de cuidados relativos à sua saúde bucal e dos filhos. Material e método: Estudo descritivo com metodologia qualitativa. Foram realizadas entrevistas com roteiro semi-estruturado, que foram audiogravadas e posteriormente transcritas, com 20 primigestas cadastradas em seis unidades de saúde da família de um município do Estado de São Paulo. Os dados foram categorizados pela técnica da Análise de Conteúdo e analisados com suporte do Modelo de Crenças em Saúde. Resultados: Foram identificadas três categorias: Percepções dos riscos e benefícios na primeira gestação, Gravidade percebida e barreiras na primeira gestação, Superação de barreiras e adoção de cuidados em saúde bucal. As gestantes acreditavam na suscetibilidade à transmissão de doenças durante a gestação, na possibilidade dos procedimentos odontológicos e certos hábitos apresentarem riscos à sua saúde e influenciarem no desenvolvimento do bebê. As principais barreiras apontadas foram o medo dos procedimentos odontológicos e a recusa ao atendimento à gestante, enquanto a família, as redes sociais e grupos de promoção de saúde foram os principais meios informativos. Conclusões:   A aproximação às percepções, crenças e atitudes de primigestas pode ampliar os conhecimentos sobre os cuidados em saúde, revelar mitos, hábitos e aprendizagens neste período, contribuir no planejamento de ações pautadas no diálogo e fortalecimento de vínculos entre profissionais da equipe e gestantes, e na promoção de cuidados em saúde bucal durante o pré-natal.

Published: February 2021

A design-oriented numerical study of vertical Si-nanowires to be used as sensing elements for the detection of the intracellular electrical activity of neurons. An equivalent lumped-element circuit model is derived and validated by comparison with physics-based numerical simulations. Most of the component values can be identified individually by geometrical and physical considerations. The transfer function and the SNR of the sensor in presence of thermal noise are derived, and the impact of the device geometry is shown.

Introduction: The aim of this study to review the socioeconomic determinants of neonatal death compared to living infants in a multinational’s population.
Methods: A retrospective data analysis of 58,990 births. Population-based Cohort study retrieved from the perinatal registry for the 4 years period. We compared socio-economic factors in cases of neonatal death [NND] who died in the hospital with infants who have discharged alive from the hospital [AL]. Socioeconomic factors including nationality, religion, marital status, level of education, parents’ occupation, family income, consanguinity, early childbearing, smoking, assisted conception, antenatal care, and place of delivery.
Results: There were 336 cases of ND and 58,654 of AL. The prevalence of NND was 5.7/1000 births. There were more neonatal deaths among uneducated mothers with P-value < 0.0003, and OR=2.0, mothers with low income (P=0.0008, CI=1.34-3.16, OR=2.07), families living in a shared houses (P=0.008, CI=1.23-3.19, OR=1.34), consanguinity (P=0.005, CI=1.13-2.0, OR=1.5), unemployed father (P=0.027, CI=1.24-4.28, OR=2.4), father’s education (P=0.017, CI=1.065-1.92, OR=1.4), assisted conception (P= 0.0001, CI=2.99-5.46, OR=4.04) and those mothers with no antenatal care (P=0.0001, CI=2.54-4.48, OR=3.37). Preterm birth in a referral/tertiary hospital was significantly high. There was no negative impact of nationality, mother’s occupation, maternal age, gravidity, or smoking. Comparing means among maternal and neonatal outcome categories showed no negative impact of crowding index (family members/number of rooms), number of rooms, number of family members, number of children in the house, or number of parties.
Conclusion: In this study, antenatal care, parent’s education, father’s unemployment, low income of the mother, poor housing, consanguinity, assisted conception, and preterm birth were all associated with in-hospital neonatal death.
Cuffed vs Uncuffed Endotracheal Tubes for Pediatric Patients: A Review
Authors: A Yim , J Doctor , S Aribindi , L Ranasinghe
Published: February 2021

The use of uncuffed endotracheal tubes (ETT) in patients younger than 8 years old has been in practice for the last 60 years. In the last decade, there has been a change in clinical practice with a transition to cuffed ETT use, and there continues to be debate between cuffed vs uncuffed ETT use. This narrative review article aims to review the current literature on the topic and highlight some key points in the argument of cuffed vs uncuffed ETT use in pediatric patients. Cuffed ETTs are increasingly being used with several studies over the last 20 years demonstrating its benefits. Studies have claimed cuffed ETT has a clinical, environmental, and economical benefit over uncuffed ETT. Despite shortcomings of various studies and no definitive conclusion of a superior type of endotracheal tube, cuffed ETTs are here to stay in the world of anesthesia.

Authors: Elsherif Entisar , Dreid Fatma
Published: February 2021

This exploratory case study aimed at investigating the student-teachers’ views on using Facebook games for language learning. The participants were 48 student-teachers at the EFL Department of the Faculty of Education at a Libyan public university. They were required to play Facebook games for two weeks and then present their experiences through oral presentations and reflective journals. Data were collected through student-teachers’ presentations and reflective journals. Data were analyzed qualitatively using a thematic inductive approach. Although few student-teachers had negative views, most of the student-teachers had positive views on using Facebook games for learning. They believed that Facebook games teach players following instructions and provide opportunities for language improvement, especially for vocabulary learning. We expect that our findings would provide teachers and practitioners with ideas for classroom research and encourage researchers to conduct further and more rigorous testing on integrating Facebook games into the EFL classroom.

The results of the possibility for using of spent ANF-6-1 fl ux for electroslag remelting and breakage of spent
silicon carbide abrasive wheels in the smelting of 20GFL steel are presented. Noticeable advantage of the
experimental smelting technology is shown. Saving of expensive materials, reduction of harmful impurities in the
metal and increase in the desulfurization rate from 0.0004 to 0.0007 %/min are noted. The use of spent ANF6-1 fl ux for electroslag remelting made it possible to reduce the duration of melting, the consumption of slagforming materials and reducing agents. There is also decrease in electricity consumption by 11 kW/h per ton of
liquid steel. Increase in the plastic characteristics and impact toughness of 20GFL steel is shown when using the
experimental melting technology in comparison with the current one. At the same time, the strength characteristics
of steel remained at the same level. The economic effect at using of secondary materials in the smelting of 20GFL
cold-resistant steel is 430...450 rubles per ton of liquid steel.

on the Fe —25Cr—35Ni system are studied by optical and electron microscopy and X-ray spectral microanalysis. Signifi cant structural inhomogeneity in various zones of the welded joint and the formation of intermetallic
G-phase in the heat-affected zone and weld metal are revealed. It is shown that the changing in the alloy structure during welding leads to signifi cant decrease in the mechanical properties of the welded joint.
Six ways to get a grip on leveraging the expertise of Instructional Design and Technology professionals
Authors: Chen Weichao , Kleinheksel AJ
Published: February 2021

We underutilize the knowledge and skills of Instructional Design and Technology (IDT) professionals, despite the frequent challenges in implementing learning technologies in medical education. This is largely due to a lack of understanding among stakeholders regarding the expertise of IDT professionals and their role in technology implementation processes. We seek to improve technology implementation outcomes by explaining the IDT field’s foundational tenets of a systems perspective and disciplined approach, clarifying the role that IDT professionals can play in educational technology initiatives, and providing guidance on how to foster productive collaborations in pursuit of effective technology-enhanced learning.
