From Goldilocks to Gump: entrepreneurial mechanisms for everyday entrepreneurs
Authors: Sarasvathy Saras D. , Forster William , Ramesh Anusha 
Published: January 2020

In this essay we argue that the exclusive focus on research aimed at isolating the characteristics of entrepreneurs as opposed to others, while intellectually exciting and even practically valuable, may have blinded us to another wholly new and exciting possibility – namely, the design of mechanisms that allow all kinds of individuals to start new ventures and provide useful and valuable tools to enable them and their stakeholders to build enduring organizations. The research stream on effectuation has identified a few of these mechanisms. By showing where effectuation may be located within the history of behavioral and experimental economics, we were led to the outline of at least three more mechanisms that could open the door to an entirely new research agenda on entrepreneurial mechanisms design that parallels the effort in experimental economics on economic systems design.
Theoretical analysis of particle size re-distribution due to Ostwald ripening in the fuel cell catalyst layer
Authors: Kregar Ambrož , Katrašnik Tomaž 
Published: January 2020

AbstractThe limited durability of hydrogen fuel cells is one of the main obstacles in their wider adoption as a clean alternative technology for small scale electricity production. The Ostwald ripening of catalyst material is recognized as one of the main unavoidable degradation processes deteriorating the fuel cell performance and shortening its lifetime. The paper systematically studies how the modeling approach towards the electrochemically driven Ostwald ripening in the fuel cell catalyst differs from the classical diffusion driven models and highlights how these differences affect the resulting evolution of particle size distribution. At moderately low electric potential, root-law growth of mean particle size is observed with linear relation between mean particle size and standard deviation of particle size distribution, similar to Lifshitz-Slyozov-Wagner theory, but with broader and less skewed distribution. In case of high electric potential, rapid particle growth regime is observed and qualitatively described by redeposition of platinum from a highly oversaturated solution, revealing the deficiencies of the existing platinum degradation models at describing the Ostwald ripening in the fuel cells at high electric potentials. Several improvements to the established models of platinum degradation in fuel cell catalysts are proposed, aimed at better description of the diffusion processes involved in particle growth due to Ostwald ripening.
Dizziness and localized pain are often concurrent in patients with balance or psychological disorders
Authors: Malmström Eva-Maj , Magnusson Måns , Holmberg Johan , Karlberg Mikael , Fransson Per-Anders 
Published: December 2019

Abstract

Background and aims
Symptoms of dizziness and pain are both common complaints and the two symptoms often seem to coincide. When symptoms appear concomitant for sustained periods of time the symptoms might maintain and even exacerbate each other, sometimes leading to psychological distress. In order to evaluate such comorbidity we studied patients referred to a vestibular unit and to a psychiatric outpatient clinic with respectively balance disorders and psychological issues.

Methods
Consecutive patients referred to a vestibular unit (n = 49) and a psychiatric outpatient clinic (n = 62) answered the Dizziness Handicap Inventory (DHI) questionnaire and a questionnaire detailing occurrence of dizziness and pain.

Results
The experience of dizziness and pain often coincided within individuals across both clinical populations, especially if the pain was located to the neck/shoulder or the back (p = 0.006). Patients who reported dizziness had significantly more often pain (p = 0.024); in the head (p = 0.002), neck/shoulders (p = 0.003) and feet (p = 0.043). Moreover, patients who reported dizziness stated significantly higher scoring on emotional (p < 0.001) and functional (p < 0.001) DHI sub-scales. Furthermore, patients who reported an accident in their history suffered significantly more often from dizziness (p = 0.039) and pain (p < 0.001); in the head (p < 0.001), neck/shoulders (p < 0.001) and arms (p = 0.045) and they scored higher on the emotional (p = 0.004) and functional (p = 0.002) DHI sub-scales.

Conclusions
The findings suggest comorbidity to exist between dizziness and neck/shoulder or back pain in patients seeking health care for balance disorders or psychological issues. Patients suffering from dizziness and pain, or with both symptoms, also reported higher emotional and functional strain. Thus, healthcare professionals should consider comorbidity when determining diagnosis and consequent measures.

Implications
Clinicians need to have a broader “receptive scope” in both history and clinical examinations, and ask for all symptoms. Although the patients in this study visited a vestibular unit respectively a psychological clinic, they commonly reported pain conditions when explicitly asked for this symptom. A multimodal approach is thus to favor, especially when the symptoms persist, for the best clinical management.

The local technical validation of new plasma tube with a mechanical separator
Authors: Ucar Kamil Taha , Aksoy Neval , Erhan Belgin , Bercik Inal Berrin 
Published: December 2019

Abstract

Background
Unsuitable samples are common problem for laboratories. The blood collection tubes need to be validated or verified prior to their being used in the routine laboratory for reducing this situation.

Objective
We aim to compare the technical qualifications of routinely used BD Vacutainer® Serum Separator Tubes™ II Advance Plus with BD Vacutainer® Barricor™ LH Plasma Tubes for local technical validation.

Materials and methods
Apparently healthy 150 voluntary subjects were enrolled in the study. Samples were collected in two separated tubes by a single phlebotomist. Twelve quality indicators were used to compare these two different types of tubes for local technical validation. Differences (%) between them were calculated with the formula proposed by EFLM. In case of any difference of less than 1% for each indicator, the evaluated tube was considered as non-inferior.

Results
Indicators, such as tubes with physical defects, that fail to create vacuum, not properly fitting into the blood collection device, under filling (10%), cracked tubes, tubes exterior surface contaminated with blood, hemolysed specimens, including fibrin strand/mass in the sample, red blood cell adhesion, poor/incomplete barrier formation were found non-inferior in Barricor™ tubes. White particulate matter (WPM) was observed in 24.6% of Barricor™. Therefore, the last indicator (tubes including gel/foreign material/WPM in sample after centrifugation) was found inferior for Barricor™.

Conclusion
Technical local validation studies should be encouraged in terms of quality management. It was thought that WPM would not cause any interference in a properly filled tube. In addition to, Barricor™ was also found to be technically acceptable when evaluated through using all other indicators.

Sistema para análisis de muestra de urocultivo a partir de la curva de crecimiento
Authors: Mar Cornelio Omar , Calderón Leyanys Acosta , Benítez Karla García 
Published: January 2020

RESUMEN: En los laboratorios clínicos de los centros médicos, se realizan un conjunto de análisis a partir de la recogida de muestras biológicas, en organizaciones pequeñas como policlínicos y hospitales no especializados. Se realiza mediante la aplicación de diversos sistemas para el procesamiento semiautomático de las muestras. Actualmente en Cuba uno de los sistemas que realiza este proceso es el Driamic. Sin embargo, al no poseer soporte técnico, no ha sido posible corregir la generación de falsos positivos en los resultados de la muestra, además no existen algoritmos que muestren las curvas de crecimiento. La presente investigación describe una solución a la problemática planteada a partir de la elaboración de un sistema basado en tecnologías libres que implementa un conjunto de algoritmos computacionales, que permiten graficar el crecimiento bacteriano, a partir de la unidad formadora de colonias (UFC)/ml que presenta una muestra en tiempo real, mediante su curva de crecimiento. Se generan además un conjunto de reportes que facilita el diagnóstico clínico y permite la visualización de los datos generados por el procesamiento de la muestra de urocultivo de un paciente.
PALABRAS CLAVES: sistema de Gestión; curva de crecimiento; urocultivo.

ABSTRACT: In the clinical laboratories of the medical centers, a set of analyzes is made from the collection of biological samples, in small organizations such as polyclinics and non-specialized hospitals. It is done by applying various systems for the semi-automatic processing of the samples. Currently in Cuba one of the systems that makes this process is the Driamic. However, since there is no technical support, it has not been possible to correct the generation of false positives in the results of the sample, in addition there are no algorithms that show the growth curves. The present investigation describes a solution to the problematic raised from the elaboration of a system based on free technologies that implement a set of computational algorithms, that allow to graph the bacterial growth, from one of the unit forming of colonies (UFC)/ml that shows a sample in real time, through its growth curve. A set of reports that facilitates the clinical diagnosis and allows the visualization of the data generated by the processing of a patient's urine sample is also generated.

Semiótica, ciberativismo e paixões nos comentários da fanpage do Movimento Brasil Livre (MBL)
Authors: Resende Natália Silva Giarola de 
Published: January 2020

RESUMO: O presente artigo tem como objetivo investigar as paixões mobilizadas pelo ciberativismo nos comentários da fanpage do Movimento Brasil Livre (MBL). O corpusse constitui de comentários da fanpage, feitos entre os dias 17 de abril de 2016 até o dia 12 de maio 2016, período do impeachment da então presidente Dilma Rousseff. Para compreender o panorama em que estão inseridas as publicações, traçaremos um rápido quadro político, assim como abordaremos teoricamente o ciberativismo. Utilizaremos como referencial teórico-metodológico autores que abordam a semiótica discursiva, tais como Greimas e Fontanille (1993), Fontanille (2015), Barros (1990, 1994), Greimas (2014) e Fontanille e Zilberberg (2001). A partir da articulação entre os fundamentos teóricos e as reflexões resultantes da análise da Semiótica das Paixões, verificaremos como os comentaristas deixam transparecer suas paixões por meio de construções passionais e como essas paixões os movem como ciberativistas nos comentários.
PALAVRAS-CHAVE: semiótica das paixões; semiótica discursiva; ciberativismo; redes sociais.

ABSTRACT:This article aims at investigating the passions mobilized by cyberactivism in the comments on the fanpage Movimento Brasil Livre (MBL). Our corpus consists of those comments from between April 17, 2016 and May 12, 2016, period of the Brazilian President Dilma Rousseff’s impeachment. To understand the context in which such publications are inserted, we will draw a rapid political framework, as well as theoretically address cyberactivism. In addition, we will use authors who approach discursive semiotics as theoretical-methodological reference such as Greimas and Fontanille (1993), Fontanille (2015), Barros (1990; 1995), Greimas (1983) and Fontanille and Zilberberg (2001). By articulating the theoretical foundations with the reflections resulting from the analysis of the Semiotics of Passions, we will verify how the commentators leave their passions through passional constructions and how these passions shape them as cyberactivists in the comments.

O uso de recursos tecnológicos e linguagem musical na aproximação de pais e filhos: uma experiência no 1º ciclo de educação musical
Authors: De Oscar Sergio Candico , Dos Santos Gomes Celso Augusto 
Published: January 2020

RESUMO: O presente artigo descreve um estudo de caso que foi desenvolvido em uma escola pública de música do Estado de Minas Gerais. A pesquisa teve como objetivo avaliar o uso do ambiente virtual de Aprendizagem Moodle na aproximação dos pais no desenvolvimento musical de estudantes do 1º ciclo do curso de educação musical, voltado para o atendimento de crianças de 6 a 8 anos. Nesse ciclo, as crianças são introduzidas ao mundo dos estudos musicais e necessitam de todo o suporte para que se sintam confortáveis. Muitas vezes a falta de conhecimentos musicais dos pais impossibilita o apoio aos filhos, que acabam ficando desmotivados e, muitas vezes, chegam até a trancar seus cursos. Neste artigo são apresentados os resultados da pesquisa que inclui a condução de entrevistas, realização de atividades no ambiente educativo virtual e a análise de relatórios de acesso dos participantes, fornecidos pela própria plataforma EaD. Como resultado, verificou-se que essa ferramenta pode contribuir significativamente na aproximação dos pais no acompanhamento dos aprendentes em suas atividades musicais e por consequência na motivação e na aprendizagem dos estudantes. Além disso, constatamos crescimento nos indicadores de proficiência musical dos alunos por meio da avaliação de habilidades e competências específicas, bem como uma sensível redução na evasão.
PALAVRAS-CHAVE: ambientes virtuais de aprendizagem; musicalização infantil; recursos tecnológicos didáticos; família e escola.

ABSTRACT: This paper describes a case study that was developed in a public music school in the state of Minas Gerais. The research aimed at assessing the use of the Moodle platform to approach parents in the musical development of students from the 1st cycle of the music education course, aimed at attending children from 6 to 8 years old. In this cycle, children are introduced to the world of music studies and need all the support to make them feel comfortable. Often, the parents' lack of musical knowledge makes it impossible to support their children, who become unmotivated and often even lock up their courses. This article presents the results of the research that includes conducting interviews, conducting activities in the virtual educational environment and analyzing access reports of participants, provided by the e-learning platform itself. As a result, it was found that this tool can contribute significantly in bringing parents closer to the learners' accompaniment in their musical activities and consequently in students’ motivation and learning. In addition, we found growth in students' musical proficiency indicators through the assessment of specific skills and competences, as well as a marked reduction in dropout.

ABSTRACT: This paper is part of a research that deals with the representation of the knowledge about good teaching practices of an e-learning tutor. The work methodology is mixed, combining both quantitative instruments, closed questionnaire type Likert, and qualitative, with a semi-structured interview. The questionnaire was elaborated ad hoc on the basis of the functions and competences of the good e-learning tutor collected by Yot and Marcelo (2013), being applied to a sample of 13 tutors belonging to the tutoring department of a business school, where higher education is taught. After the analysis of the quantitative data, an e-learning tutor was determined as an agent of good practices on the basis of the satisfactory answers and the established criteria, to which the interview was subsequently carried out in order to be able to make an approach to its digital competence. The data obtained from the questionnaire were analyzed through the SPSS software, while those from the interview were analyzed through the Atlas.ti qualitative software. Finally, they were represented in two concept maps: the first one gathers the data referring to the contact with the students and the teaching methodology, and the second one shows the aspects related to the management of the contents and answer for questions.
