A Alfabetização Científica Inerente à Formação de Professores: o que dizem as pesquisas quanto às perspectivas para o Ensino de Ciências
Authors: Bueno Teresa Beatriz , Sedano Luciana
Published: December 2020

Diversas pesquisas têm investigado o ensino e a aprendizagem das ciências com enfoque na Alfabetização Científica (AC), visando uma formação de cidadãos que vá além das aprendizagens conceituais. Porém, poucas delas investigam a formação dos professores para a atuação nas salas de aula quanto à sua aproximação com os processos de AC. Sendo assim, o objetivo do presente texto foi analisar o perfil dos estudos, com enfoque para a formação de professores, sobre as estratégias de ensino utilizadas para promover a AC e como essas abordagens de ensino têm se aproximado de discussões sobre a prática científica. Para isso, realizou-se uma pesquisa bibliográfica nas principais revistas da área de Ensino de Ciências e nos anais do Encontro Nacional de Pesquisas em Educ¬ação em Ciências (ENPEC) do período de 2014 a 2019. As categorias de análise foram: sentidos/significados atribuídos pelos professores à AC; abordagens e estratégias utilizadas nos processos formativos com foco na AC; reflexão e delineamento acerca da prática pedagógica objetivando a AC. Identificamos poucos trabalhos no contexto formativo, inicial e continuado, dos professores. Os resultados destacam que ainda há pouco aprofundamento quanto às discussões dos aspectos que contemplam os objetivos da AC. A ideia de refletir sobre suas características é incentivada nos trabalhos, contudo a reflexão pauta-se ainda em uma ideia mais generalizada, sem que se discuta com afinco a mudança para a prática dos professores. Ainda assim, alguns trabalhos destacam as atividades investigativas como principal meio de promover a AC, uma vez que direcionam os professores à criticidade e reflexões, entre outras habilidades necessárias para uma pessoa ser alfabetizada cientificamente. Ressaltamos então a importância de incorporar na formação de professores ações que viabilizem uma mudança de atitudes quanto à sua prática em sala de aula na educação básica.
Resolução de Problemas e Problemas Abertos: Uma Investigação no Ensino de Física
Authors: Furtado Ubiratãn José , Leonel André Ary
Published: December 2020

Este trabalho aborda uma investigação acerca da resolução de problemas no Ensino de Física no âmbito da disciplina de Estágio Supervisionado, realizado em uma turma do segundo ano do ensino médio, tendo como objetivo principal analisar o engajamento dos alunos em práticas de resolução de problemas. Os fracassos observados em avaliações baseadas em resolução de problemas demonstram a necessidade de se trabalhar este assunto em sala de aula por parte do professor e de toda a escola. Estudantes, sem uma preparação para tal, são incapazes de resolver problemas de lápis e papel e problemas abertos em física. A resolução de problemas abertos vai ao encontro de posições filosóficas que defendem uma postura mais ativa do aluno durante o processo de ensino-aprendizagem. Entre outros benefícios, a resolução de problemas contribui para o aprendizado da teoria, para dinamizar a aula e para formar cidadãos mais conscientes do mundo ao seu redor e do impacto de suas ações nele, inclusive fora de sala de aula. Conclui-se então que a resolução de problemas, principalmente os abertos, é uma ferramenta útil em vários aspectos no processo de ensino-aprendizagem, além de ser de baixo custo material, ou seja, não demanda a presença de grandes recursos, podendo ser trabalhada em praticamente qualquer escola.

Published: December 2020

La enseñanza de la gramática del español como lengua materna en secundaria ha sufrido algunos cambios con motivo de las diferentes leyes educativas. Todas ellas comparten, sin embargo, un análisis funcional para el estudio de la gramática que se limita a la identificación de funciones gramaticales. En este artículo tratamos un grupo de sintagmas que producen problemas bajo esta perspectiva: los complementos locativos. A partir de una reflexión sobre cómo han de ser analizados estos complementos proponemos un conjunto de actividades que creemos que contribuyen a desarrollar en los estudiantes la capacidad de reflexión sobre la lengua, así como a incentivar el estudio de la gramática en estas etapas.

The purpose of this article is to explore how crowdfunding can ease barriers of entry into new markets. Drawing from strategic management, planning, marketing, and technology acceptance literature, we present a conceptual model to explain the use of crowdfunding by small businesses and entrepreneurs. Factors that impact individuals’ propensity to utilize crowdfunding as a source of capital include ease of use, intention to use, attitudes toward use, and effectiveness.
Managing Uncertainty in Chronic Illness From Patient Perspectives
Authors: Brown Amanda , Hayden Susan , Klingman Karen , Hussey Leslie C
Published: December 2020

Chronic illness is an increasing concern in the United States as the Centers for Disease Control and Prevention reports that 50% of adults have at least one chronic illness. When individuals must adjust to chronic illness, they may experience uncertainty regarding the illness, prognosis, and symptoms. The purpose of this qualitative, phenomenological study was to explore the management strategies of uncertainty in chronic illness from patients’ perspectives. Merle Mishel’s uncertainty in illness theory was the framework used to explore the lives of individuals diagnosed and living with chronic illness. In-depth interviews were conducted with eight individuals who have chronic disease. Results revealed themes that individuals with chronic illness do experience uncertainty and that it impacts almost all aspects of their lives. Some of the themes identified were chronic illness, uncertainty, impact of uncertainty on daily living, coping or managing uncertainty, and communication from the healthcare team about uncertainty. The individuals expressed changes in daily activities and retraining their minds to accept their new normal. This study offers coping and management strategies that healthcare professionals can implement into treatment plans to improve the quality of life for individuals with uncertainty in chronic illness. The information produced from this study will aid healthcare providers in understanding the need to address the uncertainty at diagnoses and offer ways to assist patients in coping and managing uncertainty

Authors: Wright Valerie , Whitehead Diane , Romano Corinne
Published: December 2020

Clinical nurses play an important role in the healthcare team. The practice question for this Doctor of Nursing Practice project explored the perceptions of RNs about their clinical leadership knowledge and competencies at a 160-bed rehabilitation hospital in a metropolitan city in the southeast United States. Thirty RNs completed the following three surveys: an 8-question clinical leadership knowledge assessment, a 17-question leadership competency assessment, and a 6-question emotional intelligence self-assessment. Fifty percent or more of clinical nurses believed that they were knowledgeable in identified components of clinical leadership. The leadership competency skills assessment revealed a wide range: from 3–6% of participants who indicated that they were not at all competent to 33–57% of participants who indicated that they felt very competent. Seventy-six percent of the participants felt positive about their emotional intelligence abilities. Recommendations to nursing leadership included workshops for clinical staff RNs on the various components of the Academy of Medical-Surgical Nurses’ model of clinical leadership: clinical practice, environment practice, emotional intelligence, and leadership competencies.
The Influence of a Science Methods Course on Prospective Elementary Teachers’ Visions of Science Teaching
Authors: Canipe Martha M , Coronado Verdugo Jessica Y
Published: December 2020

Prospective elementary teachers may enter their teacher education program having experienced science more as a collection of definitions and facts than in ways that support rich engagement with scientific phenomena. As a result, their visions of themselves as science teachers may not align with the most recent understandings about how to teach science to support student learning. Science methods courses are settings that have the potential to shift prospective teachers’ visions of science teaching. We used an explanatory sequential mixed methods approach with collection of survey data followed by interviews with selected participants. We analyzed how prospective elementary teachers’ visions of science teaching shifted over the course of a one-semester science methods course and what experiences they felt most influenced their visions of teaching science. We found that the visions of science teaching shifted towards or maintained alignment with the principles of science teaching introduced in the science methods course. Additionally, the prospective teachers identified model science activities and explicit connections between these activities and how students learn science as having influenced them in terms of how they thought about teaching science.
Considering Educators’ Perceptions of Ethics and Safety in Virtual Learning Environments (VLEs)
Authors: Steele Patricia B , Burleigh Cheryl , Young Elizabeth A
Published: December 2020

With the proliferation of students’ abilities to use technology, in particular virtual reality (VR) applications, teachers are experimenting with VR in virtual learning environments (VLE) to engage students; but clear ethics and safety guidelines are not available. Within the field of education additional research is needed to determine how VR is employed in VLEs. Additionally, what are the decision-making processes of educators for the VR programs chosen for classroom use based on ethics and student safety? Through qualitative inquiry, educators from K–12 and higher education shared their perceptions of ethics and safety concerns in VR applications for use in the classroom. We collected data from a sample of K–12 and higher education professionals from the Association for Educational Communications and Technology (AECT) membership, an educational organization emphasizing technology integration and learning. Data analysis from the individual interviews with open-ended questions revealed five primary themes and twelve sub-themes. Participants agreed that they need ethical and safety guidelines as they embark on new horizons that influence student well-being. The findings from this study may provide an in-depth understanding of the importance of developing ethics and safety guidelines for educational VR programs when used by students.
The Lived Experiences of Low-Income Mothers Raising Children with Autism
Authors: Sullivan Renee L , Stadtlander Leann
Published: December 2020

Previous studies indicated that parents raising children with autism spectrum disorders (ASD) experience higher rates of stress; however, no qualitative studies have addressed low-income parents’ lived experiences of raising children with ASD. The purpose of this basic qualitative study was to understand the challenges that low-income parents of children with ASD face daily within the framework of family systems theory. Interview questions were used to focus on the impact of income and the core symptoms of ASD (social deficits, communication deficits, and repetitive behaviors) on marital and interpersonal relationships. Although the study was open to both mothers and fathers, only mothers participated in this study. Semi-structured interviews with 13 mothers were conducted, and transcripts were analyzed for themes. Results indicated some negative impacts on parents’ marital, social, and professional relationships. Themes included reports of stress and depression, decreased social interaction, low levels of personal and professional satisfaction, and decreased marital satisfaction. Results indicated that increased empathy and understanding of mothers’ challenges are needed to improve access to resources and services required for low-income parents of autistic children to enhance their family’s quality of life.
Insidious Trauma, Heteronormative Steeping, and Help-seeking: Exploring the Rural Non-Heterosexual Experience
Authors: Towns Jennifer
Published: December 2020

Non-heterosexual (NH) individuals are often exposed to stressors based on their non-heterosexual status and, therefore, may have unique needs related to help-seeking for mental health, especially in rural areas where residents are more likely to identify as religious or conservative, groups that have historically been opposed to NH individuals. This study was completed to explore the lives of 10 non-heterosexual individuals in rural northern Michigan related to their daily encounters with minority stress and their experiences with help-seeking for mental health symptomology. In-depth semistructured interviews were conducted, and transcriptions were analyzed to identify the occurrence of traumatic experiences at a systemic/interpersonal level, subsequent internalization of those experiences, how that prompted the need for counseling, and the individual experiences within those therapeutic encounters. Thematic analysis identified three themes: (a) experiences of distal stressors and proximal stress reactions related to environmental and interpersonal interactions, (b) heteronormativity and heterosexism within the help-seeking process, and (c) suggestions for improving the help-seeking process. The results of this study include increasing awareness of, and focus on, the NH population in rural northern Michigan, which may have increased negative experiences based on minimal community acceptance, few affirming and diversity-educated mental health provider options, and negative provider reactions. The knowledge generated from this study could lead to increased awareness of the insidious environmental trauma experienced by NH individuals in rural conservative areas and reduce the disparities for this population by improving provider awareness and services.
A Review of Mixed Methods Community-Based Participatory Research Applications in Mental Health
Authors: Jones David E. , Lindquist-Grantz Robin , DeJonckheere Melissa
Published: December 2020

The aim of the paper was to methodologically review the intersection of mixed methods research (MMR) and community-based participatory research (CBPR) in the field of mental health research. We classify this intersecting approach as MMCBPR. The methodological review of empirical literature was conducted between October 2017 and March 2020 of full-text articles in Scopus, Pubmed, ProQuest Central, Web of Science, and EBSCOhost search engine databases in the English language. Twenty-nine studies meeting the inclusion criteria were included in the final analysis. We found some evidence of MMCBPR but it was limited by factors such as a lack of explicit rationales for the use of MMR and CBPR, limited evidence of long-term commitment to a community, and an ad hoc approach to the application of MMR and CBPR. These findings informed the development of practical recommendations for psychologists, mental health professionals, and researchers in the application of MMCBPR. In particular, our MMCBPR recommendations aim to advance the social justice agenda in counseling psychology, increase the rigor of MMCBPR approaches in mental health studies, and inform how advanced mixed methods applications can be used to address the complexities associated with mental health and well-being.

The study aims to assess the relationship between the body structure, physical fitness, and functional parameters of the respiratory system of the cadets from the General Tadeusz Kościuszko Military University of Land Forces (AWL) and their results in passing selected obstacle courses. The research material was collected from testing cadets of the third year of management studies. The research included anthropometric measurements, physical fitness tests, spirometry, and tests determining the level of passing selected obstacle courses. Body height and weight were measured. The body mass index was also calculated. Besides, the following functional characteristics were measured: cardiopulmonary endurance, functional strength, running speed and agility, balance, forced expiratory volume in 1 second, forced vital capacity, and peak expiratory flow. The study also included tests determining the level of passing the land and water obstacle courses. Statistically significant relationships were found between height and weight, balance, and forced expiratory volume in 1 second. Moreover, there were correlations between body weight and body mass index and the results in passing the land obstacle course. In addition, there were connections between cardiopulmonary endurance and performance in passing the land obstacle course, body balance, and performance in passing the land and water obstacle course. All the relationships mentioned above were low and statistically significant.
Possibilities of using the Polish Armed Forces in non-military crises in the aspect of changes in the command and control system
Authors: Sobolewski Grzegorz
Published: December 2020

In the past, the main task of the Armed Forces was primarily to ensure military security in terms of defense of independence, sovereignty, and territorial integrity of the state. However, nowadays, in the national and international dimension, their scope of tasks has been expanded to include projects in the field of supporting public administration bodies and society in crisis situations. That is due to the fact that the Armed Forces have unique, unprecedented in other response forces, opportunities to take effective action in the event of various crises. Thus, they have become an important enhancement of the crisis management system and civil protection. They can often constitute the main element of support for public administration bodies (central and local government) in solving emerging crisis situations. An important factor in the effectiveness of their actions in helping the society is the so-called crisis management system in the Ministry of National Defense. The structure of this system is closely related to the functioning control and command system.

Habilidades Socioemocionais e Tecnologias Educacionais: Revisão Sistemática de Literatura
Authors: Versuti Fabiana Maris , Mulle Rafael Lima Dalle , Guerreiro Carlos Antônio Rodrigues , Martins Flavio Pinheiro , Peralta Deise Aparecida
Published: December 2020

O presente artigo realizou uma revisão sistemática de literatura relacionando tecnologias educacionais e habilidades socioemocionais. Para isto, foi utilizada a plataforma de evidências SUMARIZE. Foram realizadas buscas em 13 bases de dados: 238 artigos foram encontrados e após leitura dos resumos estruturados (screening), 25 artigos foram selecionados para serem lidos na íntegra, ao final do processo restaram 10 artigos aceitos para revisão sistemática. O conceito de tecnologia educacional aqui considerado é o de um escopo amplo: toma por base abordagens "usuais" como aquelas relacionadas a digitalização (ambientes virtuais por exemplo), bem como a perspectiva ampliada sobre treinamentos e práticas para agentes educacionais. A síntese dos estudos permite observar um campo de intersecção dos saberes ainda em desenvolvimento com um espectro diverso de abordagens. Nota-se também a amplitude do conceito de tecnologia educacional tomado aqui como base e que transita de abordagens usuais como a dos ambientes virtuais de aprendizagem até a validação de escalas e treinamentos específicos para agentes educacionais. Assim sendo, verifica-se uma polissemia de sentidos acerca da temática, que gera obstáculos à produção baseada em evidências. Os achados deste estudo evidenciam que o aumento no discurso das políticas públicas educacionais acerca da relevância do desenvolvimento de habilidades socioemocionais consideradas cruciais à promoção do sucesso na escola e na vida e ao desenvolvimento integral do indivíduo se deu de forma desarticulada com os avanços de investigações na área, e reiteram o distanciamento entre o conhecimento acadêmico e cotidiano escolar. Sendo assim, estudos desta natureza, com definição clara dos construtos não só são pertinentes, como são urgentes.

Published: December 2020

Pesquisas relacionadas à temática das Habilidades para Vida vem sendo tema de investigações científicas que têm evidenciado e esclarecido como se dão os processos comportamentais e socioemocionais relacionados com dimensões essenciais para êxito ao longo da vida, tais como atendimento as demandas acadêmicas, sociais e profissionais, relacionamentos interpessoais, entre outros. Tomando-se como referência o ambiente escolar, um dos pontos chave para o desenvolvimento destas habilidades, este estudo visa sintetizar as evidências disponíveis no panorama da literatura científica brasileira acerca de intervenções focados em desenvolvimento de Habilidades para Vida, que utilizem Tecnologias Digitais Educacionais como ferramenta interventiva, nos últimos dez anos. Para isto, foi feito uma revisão sistemática de literatura, que compreendeu etapas subsequentes e encadeadas, em formato baseado no modelo da Plataforma Evidências – Módulo Sumarize (SUMARIZE), que foi utilizado para as etapas de buscas e de redação deste artigo. O SUMARIZE foi utilizado para orientar o desenvolvimento de protocolos de revisões sistemáticas que ajudaram os autores a melhorarem o relato de revisões sistemáticas e meta-análises, como é o escopo desta pesquisa. Os principais resultados concentram-se em dez artigos que abarcaram de modo articulado os dois construtos, Habilidades para Vida e tecnologias digitais educacionais. Em linhas gerais, evidencia-se que o ambiente escolar é um espaço subaproveitado para inserção das tecnologias educacionais como mediadora de acesso à aprendizagem, com grande potencial para o trabalho com Habilidades para Vida.

Authors: Menezes Suzy Kamylla de Oliveira , Francisco Deise Juliana
Published: December 2020

A pandemia por COVID-19 proporcionou mudanças repentinas na sociedade. Esse cenário inesperado e incerto afeta profundamente as instituições educacionais em diversos países, incluindo o Brasil. As Tecnologias Digitais da Informação e Comunicação (TDIC) são apontadas quanto a sua aplicação no ensino a fim de amenizar os impactos da suspensão presencial das aulas, contudo uma série de repercussões sociais e afetivas perpassa as questões educacionais no período de pandemia. Refletir criticamente sobre essas questões é fundamental para contribuir nas estratégias educacionais adotadas durante a pandemia, bem como pós-pandemia. O objetivo deste trabalho é analisar impactos sociais e afetivos sobre o processo ensino-aprendizagem gerados pela pandemia por COVID-19. Para isso, foi realizada uma revisão sistemática da literatura para identificar trabalhos sobre a temática. Foram selecionados 26 trabalhos relacionados com o objetivo da pesquisa. Nos resultados, destacam-se estudos qualitativos e conceituais sobre aspectos sociais e afetivos no contexto educacional, abordando as implicações do ensino online, propostas de métodos de ensino, TDIC a serem aplicadas em ambiente de ensino online ou modelos de ambientes de ensino online. A maioria dos trabalhos é de origem chinesa e tem foco na universidade. Conclui-se que há a necessidade de planejar estratégias que visem lidar com os impactos da pandemia para professores, estudantes, bem como gestão educacional. Esses impactos são afetivos e sociais e envolvem a complexidade dos contextos em que as pessoas estão inseridas. Embora as propostas de plataformas de ensino online se sobressaiam, são necessários estudos sobre as funcionalidades que elas oferecem e como afetam a experiência de ensino-aprendizagem, bem como recursos financeiros para investimento em conectividade de professores e estudantes, além de processos de formação de professores para que se apropriem didaticamente das mesmas.

Published: December 2020

Recentemente, pesquisas em IoT tem sido direcionadas a novos desafios relacionados a um cenário mais amplo de disponibilidade massiva de dispositivos. No entanto, a concretização desse cenário massivo em um ambiente real é onerosa e algumas vezes inviável. Neste trabalho propomos um ambiente de geração massiva de dispositivos virtuais de Internet das Coisas que uniformiza o processo de interação e a estratégica de descrição dos dispositivos virtuais, adotando a recomendação W3C Web of Things. Para validar a proposta, foi conduzido um experimento que gerou um conjunto massivo de dispositivos virtuais e avaliou o tempo de execução e a funcionalidade dos dispositivos gerados.
Uma Proposta de Protocolo MAC com Redução de Sobrecarga para Redes de Sensores sem Fio
Authors: Fermino Gunnar , De Moraes Renato
Published: December 2020

Em redes de sensores sem fio (RSSFs) a eficiência energética é o principal problema de pesquisa. Tendo em vista a limitada reserva de energia dos nos sensores e o alto custo energético para transmitir e receber dados, definir a quantidade de dados de controle necessários à manutenção da RSSF é um grande problema. Este trabalho apresenta o MAC-RSPC, uma proposta de protocolo MAC para Redução de Sobrecarga de Pacotes de Controle, destinado a RSSFs multicanais e homogeneas. O MAC-RSPC segue a abordagem cross-layer e visa a eficiência energética. A técnica de redução de sobrecarga visa diminuir a quantidade de dados de controle que circulam na rede sem, no entanto, diminuir a qualidade dos dados disponíveis para manutenção da estrutura da rede e construção de rotas.
AtTune: A Heuristic based Framework for Parallel Applications Autotuning
Authors: Rocha Hiago , Schwarzrock Janaina , Pereira Monica , Schnorr Lucas , Navaux Philippe , Lorenzon Arthur , Beck Filho Antonio Carlos Schneider
Published: December 2020

Several aspects limit the scalability of parallel applications, e.g., off-chip bus saturation and data synchronization. Moreover, the high cost of cooling HPC systems, which can outweigh the cost of developing the system itself, has pushed the parallel application’s execution to another level of requirements, in terms of performance and energy. In this work, we propose AtTune: a heuristic-based framework for tuning the number of processes/threads and CPU frequency to optimize the parallel applications’ execution. AtTune is transparent for the user, independent of the input size, and it optimizes for different parallel programming models. We evaluated our proposed solution considering five well-known kernels implemented in MPI and OpenMP. Experimental results on two real multi-core systems showed that AtTune improves up to 36%, 11%, and 32% the energy efficiency, performance, and Energy-Delay Product, respectively.

Authors: Oliveira Nicomar , Moura Pedro , Campos Carlos
Published: December 2020

Sinais de trânsito são elementos fundamentais que servem de alerta e orientação à direção autônoma de veículos. Nesse sentido, um dos principais problemas de pesquisa abordados na literatura relacionada é o de classificação automática de sinais de trânsito. Uma vez que veículos autônomos podem ser utilizados em diferentes países, onde os sinais de trânsito podem ter diferentes símbolos e significados, e necessário que os classificadores sejam capazes de se adaptar de acordo com o conjunto de sinais de cada país. Dado isso, este trabalho propõe o treinamento de modelos de aprendizado de máquina utilizando datasets públicos de placas de trânsito de diferentes países, com o objetivo de gerar classificadores suficientemente robustos para utiliza-ção nesses diversos países. Assim sendo, são apresentadas algumas estratégias para treinamento dos modelos de classificação, bem como uma avaliação experimental dessas diferentes estratégias, sendo destacada aquela que levou aos melhores resultados.

Published: December 2020

Object Detection is a challenging task in computer vision, but Deep Neural Networks (DNN) have made great progress in this area. This work presents the process and the results obtained in the attempts to embed a YOLO V3 model in a Neural Compute Engine, the Movidius Stick. Experiments were carried out with a Tensorflow model that is converted to Movidius (using OpenVINO) including an evaluation of the Movidius stick connected to a Raspberry Pi3. The application uses aerial images of power distribution towers captured by a drone. Although there are some fully operational networks for Neural Compute Engines, there are some difficulties in porting new networks to the platform, with gains in performance, but with losses in accuracy.

Džon Rols: O liberalizmu i pravednosti
Authors: Stepanov Radivoj
Published: December 2020

Teorija pravde Džona Rolsa u pravno-teorijskim i političko-filozofskim krugovima, intenzivno je raspravljana na širokom tematskom području od polaznih i temeljnih principa političke filozofije liberalizma do etičkih i moralnih principa pravde i pravednosti. Otuda je njegov teorijski rad na području prava, morala i političke filozofije, predstavljao inspirativan "predtekst" celoj generaciji mislilaca poslednjih decenija XX veka u njihovim analitičkim radovima i kritičkim razmišljanjima o pravdi pravičnosti, slobodi i jednakosti. Dva osnovna smera njegovih razmišljanja se međusobno prepliću i dopunjuju: politički liberalizam (political liberalisam) i pravda kao pravičnost (justice as fairness). U prvom slučaju, liberalno učenje o socijalnoj pravdi ima za cilj da ideal slobode pomiri sa idealom jednakosti. To znači da svakom pojedincu ili građaninu pripada određen skup dobara "samim tim" što je član jedne (političke) zajednice. Pošto se poželjni nivo jednakosti ne može odrediti u bilo kom "meritornom organu" prepušteno je demokratskim ustanovama da odrede nivo socijalnih davanja u skladu sa sukobljenim zahtevima privredne efikasnosti i socijalne pravde. Drugi smer Rolsovih razmišljanja o pravdi kao pravičnosti sadrži dva osnovna načela. Prvo načelo određuje da svako ima jednako pravo na najširi potpuni sistem jednakih osnovnih sloboda koji je saglasan sa sličnim sistemom slobode za sve. Drugo načelo zahteva da se socijalne i ekonomske nejednakosti urede u svrhu najveće moguće dobrobiti najslabije stojećih, i da se odnose na službe i položaje dostupne svima pod uslovima pravične jednakosti mogućnosti. U teoriji, prvo načelo ima prvenstvo pred drugim načelom. Otuda Rols nalazi da teorija pravednosti kao pravičnosti i predstavlja oblik političkog liberalizma.

Authors: Čeči Đerđ
Published: December 2020

The author analyses in this work development of Hungarian legislature related to trademarks belonging to the period of time between late seventies and present day. He points out that since the reform of legal system and transition to market economy numerous statutes have been passed in order to harmonize civil legislation dealing with consumer protection with the demands of market economy. Some of those statutes have been Law on Product Responsibility (1995), Law on Prohibition of Distorted Competition on Market (1990). Trademarks have been regulated by the XI Statute of 1977. This Statute contains numerous and usual notions related to consumer protection. Some of those notions have effect of an absolute or unconditional exclusion from the trademark protection, especially if they may be misleading for consumers in respect of kind. quality, geographic origin or other features of goods and services.
The state liability for damages caused by its judicial authorities
Authors: Mihailović Nikola
Published: December 2020

A breach of any right or freedom under the Convention for the Protection of Human Rights and Fundamental Freedoms, leads to but is not limited to liability of the State for damages. That liability is much stricter than the State liability for damage provided according to the domestic law provisions currently in force. The current provisions on State liability for the work of its judiciary do not include the damage caused by improper interpretation and application of the relevant legal provisions. In contrast, the liability of the Council of Europe Member States for the damage caused by their judicial and other authorities, through the breach of the human rights and fundamental freedoms guaranteed by the Convention includes their liability for improper interpretation and application of the relevant provisions of the Convention. That liability is so strict that it in fact comes equal to no-fault liability, from the point of view of its legal consequences. This is so, although it is regulated only as a presumed liability for which there are no grounds of limitation. As a result, two systems of liability for damage caused by judicial authorities will exist in our State Union and in its member states, after the ratification of the aforementioned Convention: liability pursuant to the domestic legal provisions and liability pursuant to the Convention. For that reason, a reform of the provisions on liability is necessary, which will lead to tightening of liability for damage caused by judiciary pursuant to the domestic rules. How to achieve this is a separate issue, which will not be discussed on this occasion.
International criminal law protection of prisoners of war in the nineteenth century
Authors: Lopičić-Jančić Jelena
Published: December 2020

The author writes about International conventions and other legal acts in the field of Law of War in the 19th century, with special emphasis on the criminal law protection of prisoners of war. She underlines that although the 1874 Brussels Declaration and the 1880 Oxford Manual of the Laws and Customs of War were not international conventions, they still represented very important international instruments, which had a great impact on the International Law of War in the 20th century. A number of principles established in those acts were later adopted in the Hague and the Geneva Conventions.
