Abstract. This paper complements a series of now four publications that document the release of the Earth System Model Evaluation Tool (ESMValTool) v2.0. It describes new diagnostics on the hydrological cycle, extreme events, impact assessment, regional evaluations, and ensemble member selection. The diagnostics are developed by a large community of scientists aiming to facilitate the evaluation and comparison of Earth System Models (ESMs) which are participating in the Coupled Model Intercomparison Project (CMIP). The second release of this tool aims to support the evaluation of ESMs participating in CMIP Phase 6 (CMIP6). Furthermore, data sets from other models and observations can be analysed. The diagnostics for the hydrological cycle include several precipitation and drought indices, as well as hydroclimatic intensity and indices from the Expert Team on Climate Change Detection and Indices (ETCCDI). The latter are also used for identification of extreme events and for impact assessment, and to project and characterize the risks and impacts of climate change for natural and socio-economic systems. Further impact assessment diagnostics are included to compute daily temperature ranges and capacity factors for wind and solar energy generation. Regional scales can be analysed with new diagnostics implemented for selected regions and stochastic downscaling. ESMValTool v2.0 also includes diagnostics to analyse large multi-model ensembles including grouping and selecting ensemble members by user specified criteria. Here, we present examples for their capabilities based on the well-established CMIP Phase 5 (CMIP5) data set.
A structural self-organizing map (S-SOM) algorithm for weather
typing
Authors: Doan Quang-Van , Kusaka Hiroyuki , Sato Takuto , Chen Fei
Published: October 2020

Abstract. In this study, we propose a novel structural self-organizing map (S-SOM) algorithm for synoptic weather typing. A novel feature of the S-SOM compared with traditional SOMs is its ability to deal with input data that have spatial or temporal structures. In detail, the search scheme for the best matching unit (BMU) in a S-SOM is built based upon a structural similarity (S-SIM) index rather than by using the traditional Euclidean distance (ED). S-SIM enables the BMU search to consider the correlation in space between weather states, such as the location of highs of lows, that is impossible when using ED. The S-SOM performance is evaluated by multiple demo simulations of clustering weather patterns over Japan using the ERA-Interim sea-level pressure data. The results show the superiority of the S-SOM compared with a standard SOM with ED (or ED-SOM) in two respects: clustering quality based on silhouette analysis and topological preservation based on topological error analysis. The superior performance of the S-SOM compared with an ED-SOM is probably independent of both the input data and SOM configuration.

Abstract. The previous comparative studies on watersheds were mostly based on the comparison of dispersive characteristics, which lacked systemicity and causality. We proposed a causal structure-based framework for basin comparison based on the Bayesian network (BN), and focus on the basin-scale water-energy-food-ecology (WEFE) nexuses. We applied it to the Syr Darya river basin (SDB) and the Amu Darya river basin (ADB) that caused the Aral Sea disaster. The causality of the nexuses was effectively compared and universality of this framework was discussed. In terms of changes of the nexuses, the sensitive factor for the water supplied to the Aral Sea changed from the agricultural development during the Soviet Union period to the disputes in the WEFE nexuses after the disintegration. The water-energy contradiction of SDB is more severe than that of ADB partly due to the higher upstream reservoir interception capacity. It further made management of the winter surplus water downstream of SDB more controversial. Due to this, the water-food-ecology conflict between downstream countries may escalate and turn into a long-term chronic problem. Reducing water inflow to depressions and improving the planting structure prove beneficial to the Aral Sea ecology and this effect of SDB is more significant. The construction of reservoirs on the Panj river of the upstream ADB should be cautious to avoid an intense water-energy conflict as SDB. It is also necessary to promote the water-saving drip irrigation and to strengthen the cooperation.

Authors: Giesel Guilherme , Brand Martha Andreia , Milagres Flaviana Reis , Damasio Renato Augusto Pereira
Published: October 2020

In pulp production, wood in logs is stored for periods that can range from a few weeks to several months. During storage, changes in the wood properties that affect the pulping process and the quality of the pulp may occur. The objective of this study was to determine the ideal timing of wood storage in logs by evaluating the variations (a) in the chemical properties of wood (b) in the parameters of the pulping process and (c) the quality of the Pinus taeda pulp. Logs were stored in an industrial courtyard for 30, 60, 90, 120 and 150 days. In each storage period, the physical and chemical properties of the wood, the cooking parameters, and the properties of the pulp were analyzed. The chemical properties of wood varied throughout storage, but only the solubility in sodium hydroxide showed a positive and significant correlation with storage time. In pulping, the yield and tailings had an inversely proportional correlation with the storage time, while the organic and total solids content had a positive correlation. As for cellulose quality, arabinan and soluble lignin contents did not vary during storage. The mannan content had a positive and significant correlation with the storage time. Taking into account all the variables analyzed, the storage time of P. taeda logs should be up to 30 days.
The Impact of Electric Vehicle Density on Local Grid Costs: Empirical Evidence from Norway
Authors: Wangsness Paal Brevik , Halse Askill Harkjerr
Published: October 2020

While a rapid shift towards electric vehicles (EVs) will contribute to reducing carbon emissions from the transport sector, there are concerns that uncoordinated charging of EVs might impose challenges for the local electricity grid. Our study is the first to investigate this empirically in a country-wide analysis, using data from the country with the highest market share of EVs, namely Norway. We present the regulatory framework in which Norwegian grid companies operate and discuss the possible impact of EV charging. Using panel data on 107 grid companies over the period 2008-2017, we then estimate the effect of local growth in EVs on local grid costs. We find that increases in EV stock are associated with increases in costs which are both statistically and economically significant. However, there is a lot of heterogeneity in these results, where the effect on grid costs are higher for small grid companies in rural areas.

PONTUAÇÕES ACERCA DO AMOR NA NEUROSE E NA PSICOSE: ENSINAMENTOS DE CAMILLE CLAUDEL
Authors: Ferrari Ilka Franco , Mendes Astarute Maria
Published: October 2020

O texto percorre o tema de parcerias amorosas, com base em ensinamentos da psicanálise freudiana e lacaniana, sem desconsiderar, portanto, que não há norma para a relação sexual e que, se há gozo autoerótico, o amor lhe faz oposição ao favorecer abertura para o Outro. Nesse percurso, elegeu-se tecer considerações baseadas em certos modos de funcionamento de parcerias amorosas, na neurose e psicose. O foco na psicose é um pouco mais ampliado, na busca de afirmar que esses sujeitos têm a possibilidade de amor, diferentemente do que se pode pensar. Por isso, Camille Claudel é convocada à cena, na busca de ensinamentos sobre o amor morto, discordante com a vida, característico da psicose, vivenciado na parceria com August Rodin.
AS POLÍTICAS PÚBLICAS PARA O AUTISMO NO BRASIL, SOB A ÓTICA DA PSICANÁLISE
Authors: Pimenta Paula Ramos
Published: October 2020

O artigo se propõe a assinalar a transposição para o âmbito das políticas públicas brasileiras da tensão epistêmica existente entre as propostas reeducativas e psicodinâmicas para o tratamento do autismo, identificando a psicanálise nesta última categoria e a terapia cognitivo-comportamental entre as primeiras. Para tanto, apresenta brevemente algumas normas brasileiras que regem a inclusão, nas políticas públicas, das pessoas com autismo. Localiza o foco de seu conteúdo nos dois documentos orientadores para o tratamento do autismo no Sistema Único de Saúde (SUS), lançados pelo Ministério da Saúde em 2013, o que possibilita explicitar a ótica da psicanálise em relação às políticas propostas. O deslocamento da tensão epistêmica para o contexto político, com a decorrente alegação legal de impedimento da psicanálise para atender as pessoas com autismo, é elucidado por alguns fatos históricos recentes, ocorridos tanto na França quanto no Brasil. A metodologia usada é a revisão bibliográfica.
O AUTISMO E SUAS CONEXÕES: QUAL MEDICAÇÃO PARA O AUTISTA?
Authors: Lopes Ana Maria Costa da Silva
Published: October 2020

Este artigo tem como objetivo discutir a conexão entre psicanálise e psiquiatria, com base na questão: qual medicação para o autista? Empregou-se como metodologia a revisão narrativa. As evidências científicas demonstram que não há uma medicação específica para o autismo, mas sintomas específicos que perturbem a funcionalidade da vida diária, tais como insônia, agressividade, agitação, entre outros, podem ser medicados. O que o analista almeja não é mudar a forma de funcionamento autístico, mas permitir a possibilidade da construção de um universo singular, de soluções que nenhum manual diagnóstico pode antecipar. Nesse sentido, a psiquiatria e seu arsenal terapêutico, por meio do ato de medicar, entram no lugar de parceiro do analista, possibilitando que o sujeito não seja reduzido a ser um simples objeto de diagnóstico, em nome de uma suposta “normalidade”. A medicação pode contribuir de forma pontual, descontínua ou, por vezes, contínua, possibilitando o percurso do tratamento analítico.

Authors: Silva Larice Santos , Silva Silvia Maria Cintra da
Published: October 2020

A entrada do estudante no ensino superior é um momento importante na vida do sujeito, com impacto nas dimensões profissional e pessoal. Tem-se como objetivo geral deste estudo, de cunho qualitativo, compreender como o ingresso no ensino superior configura a constituição do sujeito como estudante, pela perspectiva teórica da Psicologia Escolar Crítica. Participaram desta pesquisa três ingressantes do curso de Psicologia da Universidade Federal de Uberlândia (UFU), Brasil. As entrevistas tiveram como mote o ingresso na universidade e ocorreram em três ocasiões distintas: o início e o fim do primeiro semestre, e o início do segundo semestre no curso. Com base nos pressupostos da Psicologia Escolar Crítica e do livro de Alain Coulon, A condição de estudante: a entrada na vida universitária, elegemos quatro eixos de análise: a) tempo da hesitação; b) tempo do estranhamento; c) tempo da aprendizagem; e d) tempo da afiliação. Esses tempos abordam o momento anterior à entrada e a escolha profissional; o estranhamento provocado pela necessidade de compreender regras e normas institucionais; a aprendizagem do ofício de estudante e a apropriação das normas e de questões relativas à universidade bem como a aprendizagem de conceitos científicos, relações com colegas, docentes e coordenador de curso. Acreditamos que a presença e o trabalho do psicólogo escolar no ensino superior mostram-se imprescindíveis nesse nível de ensino que, além de envolver processos de escolarização e humanização, é responsável pela formação profissional de um cidadão, que precisa ser cuidado em seus aspectos cognitivos, afetivos, sociais, éticos e estéticos.

A Developmental Role for Militaries in Africa: The Peace Engineering Corps Solution?*
Authors: Zimmermann Nils , Matisek Jahara
Published: October 2020

In many African states, the military is one of very few technically capable large institutions. Based on interviews with pan-Africanist intellectuals and security experts, this article shows how a “Peace Engineering Corps” concept could be operationalized by putting suitably trained professional military units to good use for civil-military cooperation and domestic development work. Such PECs would harness the military’s logistical, technical, and administrative capabilities in support of the implementation of the United Nations Sustainable Development Goals (UN SDGs), providing environmental remediation, civil infrastructure expansion, and natural disaster response services. Western militaries could empower African partner forces in this regard by tailoring security assistance missions towards establishing and developing PEC capabilities, thereby supporting development, peacebuilding, and regional security efforts. We also note the potential for a pan-African civilian uniformed Peace and Development Corps, distinct from military PECs, in peace-building and economic development.
Histopathologic Features of Chilblainlike Lesions Developing in the Setting of the Coronavirus Disease 2019 (COVID-19) Pandemic
Authors: Sohier Pierre , Matar Stéphanie , Meritet Jean-François , Laurent-Roussel Sara , Dupin Nicolas , Aractingi Selim
Published: October 2020

Context.—

During the coronavirus disease 2019 pandemic, several studies have described a distinctive cutaneous manifestation with a clinical picture resembling chilblains or chilblain lupus in young patients.

Objective.—

To report the histopathologic description of a series of chilblainlike lesions appearing in the context of the severe acute respiratory syndrome coronavirus 2 epidemic.

Design.—

The study included 13 patients with cutaneous acral lesions resembling chilblains occurring in the setting of suspected severe acute respiratory syndrome coronavirus 2 infection with available skin biopsy.

Results.—

Two main histopathologic patterns were observed: a chilblainlike histopathologic pattern (10 of 13 cases; 77%) and a thrombotic vasculopathy pattern (3 of 13 cases; 23%). The chilblainlike histopathologic pattern featured a superficial and deep perivascular infiltrate of lymphocytes of varying intensity. This infiltrate was sometimes peri-eccrine and alterations of eccrine glands were present in most cases. Vacuolar alteration of the basal layer of the epidermis was found in a majority of patients. Lichenoid interface dermatitis was rarely present. The thrombotic vasculopathy pattern featured an absent or mild inflammatory infiltrate, multiple intraluminal fibrin thrombi, and ischemic epidermal necrosis. In both patterns, no true vasculitis was observed. No patient tested positive for severe acute respiratory syndrome coronavirus 2 by polymerase chain reaction, possibly because these lesions may represent late cutaneous manifestations of the disease or are associated with an early effective immune response.

Conclusions.—

The relationship of chilblainlike lesions to severe acute respiratory syndrome coronavirus 2 requires further investigations. Histopathologic features mimic chilblains, chilblain lupus, and, less frequently, a thrombotic vasculopathy. Response to viral infection might trigger diverse mechanisms leading to the 2 histopathologic patterns described.
Socio-economic aspects of cash withdrawal from use
Authors: Stojmenović Marija
Published: October 2020

The notion of a cashless society is slowly becoming an inevitability of the modern way of doing business. Withdrawal of cash from use is the result of wide application of information and communication technologies. Increasing digitalization has contributed to the fact that most transactions are performed via smart devices (phones, tablets, desktops), without the use of cash and without going to the bank. The development of technological innovations, as well as innovations in finance, has undoubtedly contributed to increasing efficiency in business, but the question is whether the increasing digitalization of life and business, which is reflected in the creation of a cashless society, is still so desirable for humanity. The paper focuses on the socio-economic aspects of withdrawing cash from use. On the one hand, states are given the opportunity to influence economic activities even more directly through their central banks, while on the other hand, the issue is raised concerning human freedoms and rights in the digital world, in which it will be possible to electronically control the entire business.

Authors: Mitrović Vladimir
Published: October 2020

The concept of "knowledge management" is increasingly becoming one of the key concepts for achieving and maintaining a competitive advantage in the new economy and management. This paper presents the basic elements and the relationship between knowledge management and competitiveness. After introductory considerations, knowledge as a strategic resource is analyzed, as well as the awareness of the importance of knowledge for achieving and maintaining competitiveness. The continuation of the paper is dedicated to research into the level of education and knowledge of employees, identification of the needs for additional knowledge and missing knowledge in business organizations of the city of Niš, followed by conclusions arising from the research. The fact is that shifting the focus towards creativity and innovation requires an even greater amount of knowledge. However, it is not enough for employees of business organizations to just possess the necessary knowledge, but also to be able to use it and share it effectively. Only the knowledge used in such way can become a source of sustainable growth and development of the business organization in question.
Conceptual framework of agricultural innovation policy in African countries
Authors: Abdassalam Ali , Mahmoud Ali , Abd Ahmed , Ali Mohamoud
Published: October 2020

The aim of the paper is to present a conceptual framework from which to develop an appropriate innovation policy in African countries. Particular emphasis is placed on agricultural innovation, their role in stimulating agribusiness and the overall development of the African continent. Increasing food production and bioenergy, improving agricultural economics, African farmers' incomes, reducing poverty and adapting to climate change are challenges that can be addressed or mitigated by innovations in the agricultural sector. Africa's agriculture is a highly unproductive sector as a result of lack of appropriate innovative technologies, credit, infrastructure, lack of knowledge, information and skills. Agricultural innovations in African countries relate to the invention of insecticides, resistant varieties, fertilizers, irrigation pumps, genetic programs, sustainable agricultural practices, etc. Across Africa, farmers are embracing "climate-smart" innovations. An example of the response to climate change is the raising of 200 million new trees. African countries need to improve educational system performance, science and technology, institutions, increase financial and human investment to build local technology capabilities and learn from the experiences of other innovative regions. Although most African countries have made significant progress in terms of agricultural innovation, the results are still not quite satisfactory.

Authors: Marčetić Marija , Mušikić Slađana
Published: October 2020

The main goal of this study is to investigate how gender differences affect attitudes towards entrepreneurship among students. Entrepreneurial attitudes are related to the intentions of self-employment, with the personal perception of the business environment and obstacles. The questionnaire used for data collection was adjusted to the goal of the research, the specifics of our entrepreneurial education and the economic environment in Serbia. Data were collected from 333 students of economics from the Academy of Vocational Studies in Southern Serbia. To test the initial hypotheses in this study, the following were used: descriptive-analytical method, in order to describe, evaluate and interpret the collected data, and within that, the non-parametric test ch2. Frequencies in responses between the sexes do not show discrepancies in questions involving knowledge of environment conditions, while there is a wide range in answers to questions related to personal preferences. Understanding the differences between male and female students can make it significantly easier for female students to fully use their entrepreneurial potentials, develop career preferences, and promote female entrepreneurship. New findings can help us regulate minor discrepancies in entrepreneurial education in this area.

Published: October 2020

The effect of freeze drying on the qualities of fresh cow milk and soy milk cheeses was investigated, with a view to preserve and present them in a more stable and portable form. The cow milk cheese and soy milk cheese used were freshly prepared with dimension of 2 x 3 cm and 0.2 cm thickness. The cow milk and soy cheese were divided into 6 portions of 100 g each. The initial properties of the cheeses samples been determined using a portion of 100 g each, the remaining 500 g were freeze dried. The nutritional, microbial and sensory qualities of the freeze dried cheeses were determined using standard methods. Results showed that freshly prepared cow milk cheese contains 54.02% moisture, 20.34% protein, 6.40% ash, 18.11% fat and 4.25% carbohydrate, 3.52mg/100g sodium, 7.02mg/100g potassium, 5.22mg/100g magnesium, 6.32mg/100g iron, 11.12mg/100g calcium, 3x103 cfu/g bacteria and 2.54 x 106 cfu/g fungi whereas freshly prepared soy cheese contains 50.89% moisture, 22.05% protein, 6.31% Ash, 19.02% fat and 4.06% carbohydrate, 3.52mg/100g sodium, 7.04mg/100g potassium, 5.14mg/100g magnesium, 6.20mg/100g iron, 10.76mg/100g calcium, 2.76x103 cfu/g bacteria and 2.60 x 106 cfu/g fungi. The moisture and fat contents of the freeze dried cow milk and soybean milk decreased significantly (P < 0.05) from 54.02% to 4.28%, 18.11% to 4.05% and 50.89% to 4.19%, 19.02% to 4.30% respectively. Freeze drying significantly decreased the bacteria and fungi contents of fresh cheeses; it decreased from 3x103 cfu/g to 2.72 x 103 cfu/g, 2.54 x 106 cfu/g to 2.35 x 106 cfu/g, and 2.76 x 103 cfu/g to 2.54 x 103 cfu/g, 2.60 x 106 cfu/g to 2.38 x 106 cfu/g for cow milk and soy milk cheese respectively. The carbohydrate, protein, ash content, calcium, sodium, magnesium, taste, appearance, flavour, acceptability of the cow milk cheeses increased significantly (P < 0.05) when freeze dried. Decreases in moisture content, fat and microbial counts of cheeses would enhance its stability and shelf life if properly packaged.

Authors: Nwabueze Onwe , Isaac Bamgboye
Published: October 2020

Cost of solvent oil extraction methods has made mechanical oil expression a desirable alternative. The effect of process variables on mechanical oil expression from sandbox seed was studied. The experimental design used for the study was a 52 Central Composite Rotatable Design of Response Surface Methodology. Experimental factors considered were: moisture content, roasting temperature, roasting time, expression pressure and expression time. Results obtained were analyzed at a0.05. The oil yield from the sandbox seed ranged from 16.38-38.68%, and was increased at processing variable ranges of (4.0-8.0%) moisture content, (80.0-90.0°C) roasting temperature, (5.0-15.0%) roasting time, (15.0-20.0 MPa) expression pressure and (6.0-8.0 min) extraction time. The maximum oil yield of 38.68% was obtained at the processing conditions of 6% moisture content, 85 °C roasting temperature, 15 min roasting time, expression pressure of 20 MPa and 8 min pressing time. Model equation relating the process variables to oil yield was developed. Coefficient of determination (R2) relating the process was 0.8908. The result showed that moisture content, roasting time, expression pressure and expression time had a significant influence on the sandbox oil yield. The results obtained in this study can serve for process and equipment designs for oil extraction from sandbox and other oilseeds and nuts.

Authors: Serafimovski Todor , Tasev Goran , Stafilov Trajce
Published: October 2020

The intense mineral extraction in mining areas during the last several decades has produced a large amount of waste material and tailings, which release toxic elements to the environment. The aim of the study was to determine in two vertical profiles/sections (1 and 2) the heavy metal contents of samples derived from six samples, three from each section located in the porphyry copper mine Buchim area, Republic North Macedonia. The results have been compared to new Dutchlist (DL) and Kabata-Pendias (KP) standards and the following was concluded: As values ranged 14.985÷60.131 mg kg-1 with 4 samples above the target value of the DL (29 mg kg-1 As) and 6 above standard values given in KP value (5 mg kg-1 As), in that context Co values ranged 11 ÷57 mg kg-1 with 6 values above the target value of the DL (9 mg kg-1 Co) and 5 above standard values given in KP value (12 mg kg-1 Co), Cr with range 29.32÷75.76 mg kg-1 with 6 over KP value (10 mg kg-1 Cr) and none above the target value of the DL (100 mg kg-1 Cr), Cu with range 2694÷6749 mg kg-1 with 6 samples above the target value of the DL (36 mg kg-1 Cu) and 6 above standard values given in KP value (20 mg kg-1 Cu), Ni with range 59.57÷105.98 mg kg-1 with 6 samples above the target value of the DL (35 mg kg-1 Ni) and 6 above standard values given in KP value (20 mg kg-1 Ni), Pb with range 27.06 ÷96.08 mg kg-1 with 1 sample above the target value of the DL (85 mg kg-1Pb) and 6 above standard values given in KP value (25 mg kg-1Pb), Zn with range 147÷273 mg kg-1 with 6 over target value of the DL (140 mg kg-1 Zn) and 6 above standard KP value (64 mg kg-1 Zn), V with range 34.44÷92.57 mg kg-1 with 5 over target value of the DL (42 mg kg-1 V) and one above KP value (90 mg kg-1 V).In order to compare the level of contamination, the contamination factor (𝐶𝑓 𝑖 ), degree of contamination (Cd), and pollution load index (PLI) were computed. Serious numbers were found for Cu, as, Zn, Co and Ni, which exceeded standard values at almost all samples from both vertical sections. Compared from section 1 and section 2, pollution load index increased by 13.43%, which in almost all samples was classified as heavily polluted to extremely polluted. The fact that mining activities at the Buchim Mine last for almost 40 years, the presence of heavy metals in soils at a serious level is understandable. The high level of contamination is a result of heavy metal persistence and non-biodegradability.

Published: October 2020

Composite materials based on acrylate UV-cured polymers (Bis-GMA/TEGDMA) as a matrix and reinforcements that can be selected in order to adjust the properties of the obtained composite are used in the field of dental technology. The role of reinforcement is to adjust the mechanical properties, but also to control the shrinkage during curing. As reinforcement, alumina particles doped with iron oxide (Al2O3 Fe) synthesized using the sol-gel technique were selected. In order to simulate the process of adhesive application in real conditions, in vitro testing technique and adhesion properties of synthesized adhesive were used, where tooth tissue was used as a substrate. Comparison with standard adhesives used in dentistry was used to compare adhesion. The quality of the adhesive joint was evaluated using the microhardness testing method using different loads where it is estimated how the adhesive makes a connection with the substrate.

The traditional management is hierarchically organized. The transition from traditional management to process management requires a radical shift in thinking from a command-and-control, personality based, top-down hierarchy to horizontal, process-oriented, team-oriented structure. Business model of an organization, implementing business process management, is realized through a network of processes. The goal of business process management is to systematically improve all processes, espesially core processes. Core processes are work processes that cross functional boundaries, produce an output that is strategically important to the organization's success and are essential for organization survival at market. Very often an organization has a set of busness processes which are improvement candidates. The problem is how to choose the set of processes whose performance improvement will do the best for organization at all. In this paper an approach for evaluation and selection of core processes is presented. The proposed approach is based on process' objects and the three-level hierarchical quality evaluation model.

Published: October 2020

In this paper, we propose an ontology-based framework for automated Web AR application code generation leveraging semantic descriptions of application structure and behavior in synergy with domain knowledge and annotations of building information model (BIM). Three case studies are presented: smart home energy consumption monitoring application, robotics testbed companion and virtual music mixing interface. The presented approach significantly reduces the time needed for Web AR application development.
The relationship between civilian and military health insurance: The condition for more efficient healthcare
Authors: Marković Damir
Published: October 2020

The aim of this paper is to analyze the relationship between the Fund for Social Security of Military Insurers and the Republic Health Insurance Fund through the aspect of more efficient use of health insurance funds. Analyzing this relationship, the system of health care in the Republic of Serbia and the health insurance system are essentially considered. Taking into account the specifics of the social protection of military insurers, efforts are being made to find out the direction and improvement of relations with the civilian health care system. Only the proactive relationship between the military and the civilian health system and the health insurance system is a condition of better health care for the insured of both funds, as well as more efficient use of health insurance funds. Health protection of the population is one of the most important social priorities and as such it must be given special attention. The right of the individual to health care, but also to other forms of protection, is realized within the framework of social insurance. Health care, and therefore the health insurance system of military insureds, developed in accordance with the specifics related to the military system itself. Fully respecting the autonomy of the said system, the development of insurance in this area evolved along with changes in the prevailing civilian health insurance system. The system of health care and health insurance is one of the most important systems in each country. The efficiency and cost-effectiveness of the functioning of this system is a challenge for every national economy. The goal that needs to be achieved is to achieve the best health care of the nation by means of available health insurance. The system of compulsory health insurance in the Republic of Serbia is implemented through a unique state organization - the Republic Health Insurance Fund. When it comes to health insurance and the protection of civil and military insurers, it is clear that these are two completely separate and independent systems that have a lot of common points and whose mutual cooperation and shared use of resources should lead to positive effects as a whole. The financial aspect, which is especially reflected through the health insurance system, is one of the most important factors because it directly affects the scope and quality of the entire health care system. Considering and analyzing the complexity of the mutual relations between the civilian and military health and social security systems, and consequently the health care system, some of the possible proposals have emerged for improvement of one of the most important aspects of every society - the health of the nation.
Modeling Expertise Through Decision-based Learning: Theory, Practice, and Technology Applications

Published: October 2020

En la educación superior, los profesores generalmente se contratan por su experiencia en el campo. Han recibido una amplia formación en la disciplina, pero han recibido una formación limitada en la enseñanza. Por lo tanto, luchan de dos maneras para enseñar y desarrollar la experiencia en los principiantes: en primer lugar, a menudo no saben cómo funciona su propia experiencia intuitiva y, en segundo lugar, carecen de una estrategia pedagógica para enseñar a los estudiantes su toma de decisiones intuitiva y experta. En este artículo, sintetizamos la literatura sobre estas dificultades para expertos. Luego, discutimos cómo DBL (aprendizaje basado en decisiones) usa el análisis de tareas cognitivas para ayudar a los expertos a hacer explícito su conocimiento y cómo DBL puede ser una solución pedagógica apropiada para muchos profesores universitarios. Finalmente, proporcionamos estudios de caso de DBL en acción y discutimos cómo la tecnología educativa puede apoyar la teoría y la práctica del aprendizaje basado en decisiones.

In higher education, faculty are generally hired for their expertise in the field. They have received extensive training in the discipline but have received limited training in teaching. Thus, they struggle in two ways to teach and develop expertise in novices: First, they are often blind to how their own intuitive expertise functions, and second, they lack a pedagogical strategy to teach their intuitive expert decision-making to students. In this paper, we synthesize the literature on these difficulties for experts. We then discuss how DBL uses cognitive task analysis to help experts make their knowledge explicit and how DBL may be an appropriate pedagogical solution for many university professors. Finally, we provide case studies of DBL in action and discuss how educational technology can support the theory and practice of Decision-based Learning.
Improving Mentoring in Higher Education in Undergraduate Education and Exploring Implications for Online Learning
Authors: Andersen Camey L. , West Richard E.
Published: October 2020

This article is a literature review of mentoring and higher education academic literature from 2008-2018. The review analyzed what makes an effective mentor and what are the implications of practice for those strategies. This article is for higher education leaders, mentoring programs, and mentors who want to improve their traditional and online mentoring programs and mentoring practices. After narrowing the search terms, the researcher searched EBSCO and ERIC databases and this search produced a combined total of 256 results. These articles were further narrowed to 34 articles that met the keyword search and exclusion criteria. The remaining articles are the focus of the literature review analysis for mentoring and higher education literature.

            The review produced three major themes of impact of mentoring, role of mentor, and mentoring programs, as well as implications for practice for each theme. The researcher further examined the themes in detail and provided information about retention, persistence, long-term benefits of mentoring, student interaction, student support, role models, types of mentoring programs, platforms for mentoring, and mentor training. The review concludes with suggestions for further research, including recommendations for mentor training and online mentoring.
Public Knowledge, Private Ignorance, and an Analytic of Knowledge Organization
Authors: Montoya Robert D. , Leazer Gregory H.
Published: October 2020

Patrick Wilson’s writings have proven to be the foundation for much of our thinking about the organization of documents and their subtle connection to power structures that govern their construction and use. His examinations of public versus private knowledge, for example, expand how we understand individual and social epistemology within the field. In his writings, however, Wilson speaks as an idealist, generally glossing over the problem of how technologies mediate and impact the relationship between people, on the one hand, and the circulation and constitution of knowledge, on the other. He did not analyze how knowledge organization structures (KO) could be effective for some people or some forms of knowledge, and ineffective for others, nor did he analyze similarly the constitutive components of KO as they relate to the differential effects on the use of knowledge. We posit that pluralistic modes of understanding KO are a fruitful way forward for the discipline. This paper conceptualizes how we can build on Wilson’s critical conversations about epistemology in the domain of KO from three specific angles: KO as pluralized space, a political economy of KO, and KO and political pragmatics.
Conception et mise en place d’un site à visée formative dédié à l’entretien d’annonce de diagnostics médicaux
Authors: Kebir Yasmina , de Almeida James , Specogna Antonietta , Saint-Dizier de Almeida Valérie
Published: October 2020

Dans l’optique de former des professionnels de santé à l’annonce de diagnostics médicaux graves nous proposons la conception d’une rubrique d’un site Web qui a pour visée de permettre à des soignants de mieux maîtriser cette activité professionnelle qu’ils redoutent. Ces diagnostics se matérialisent à travers des interactions langagières entre médecins et patients qui sont chargées d’émotions. L’analyse de ces entretiens d’annonce suppose l’accès aux interactions les plus proches possibles de celles des situations réelles de travail via des jeux de rôle. Nous montrerons que la conception de la rubrique basée sur la dimension architecturale (structure fonctionnelle de l’activité), la dimension relationnelle (rôles, contrat de communication coconstruit) et la dimension communicationnelle (procédés langagiers mobilisés) permet de cerner cette activité professionnelle sensible dans ses aspects caractéristiques. En nous basant sur une étude commanditée par la Ligue contre le cancer, nous montrerons comment et en quoi les dimensions repérées ont un potentiel formatif et nous mettrons en exergue leur apport pour améliorer la compréhension de l’activité et développer des supports de formation.
Mise en lumière des dynamiques de coproduction de connaissances lors d’entretiens collectifs collaboratifs
Authors: Morrissette Joëlle
Published: October 2020

Cette contribution vise à examiner les dynamiques qui ont émergé d’une démarche de recherche-formation collaborative ayant misé sur des entretiens collectifs, afin d’éclairer le phénomène grandissant de l’intégration professionnelle d’enseignants formés à l’étranger (EFÉ) dans les écoles québécoises qui semble problématique sous divers aspects. Une analyse de conversations a été déployée pour identifier comment se négocient les expertises d’une culture de recherche et de cultures professionnelles au service d’une démarche de coproduction de connaissances jugées pertinentes par les deux communautés concernées. Trois dynamiques ont été identifiées : le développement d’une posture compréhensive, la production de nouvelles interprétations ajustées et l’affirmation de sa compétence d’acteur. La mise en lumière de ces dynamiques amène à réfléchir aux stratégies de conception du dispositif collaboratif et d’animation des entretiens collectifs servant la démarche de coproduction de connaissances.
