Obtaining a Set of Recommendations for Evolving Executable Languages towards Systems-of-Systems Architecture Design
Authors: Lebtag Bruno G. A. , Graciano Neto Valdemar Vicente
Published: April 2021

Systems of Systems (SoS) are complex systems composed of managerially and operationally independent constituent systems (CS). Smart cities are examples of SoS. However, these types of systems impose challenges to traditional software architecture such as highly evolutionary architecture due to the evolution of individual CS and emergent behaviors that results from the interoperability of CS. Executable Models (ExM) are a class of models that can be executed and that can assist on architectural design of SoS. By using them, architects can predict the SoS structure and behavior by visualizing and simulating the SoS still at design-time. On the other hand, as any other emergent technologies, it suffers with absent scientific evidences of its benefits, mainly in industrial context. The main contribution of this master thesis project intends to be the presentation of evidences about the use of ExM to solve problems in the SoS software architecture design. For achieving such purpose, this project is structured in well-defined steps: (i) a systematic mapping study, (ii) elaboration of a conceptual map derived from the mapping study, (iii) a survey to obtain perceptions from software engineering professionals on the use of ExM in the context of engineering simple systems and (iv) a new survey expanding the previous study and to obtain perceptions from software engineering professionals on the use of ExM in the context of architectural design of SoS. Preliminary results reveal that ExM have been reported in diverse SoS domains, offering a dynamic and interactive view to the SoS. We also found that software engineering professionals see ExM as suitable solution for dealing with complex and critical systems as SoS.

Diversos estudos na área de Educação em Engenharia de Software expressam as dificuldades ou desafios de aprendizagem de estudantes, ou como os estudantes reagem a uma nova abordagem de ensino utilizada pelo professor. Assim, poucos estudos exploram as dificuldades ou desafios enfrentados pelos professores de Engenharia de Software, especialmente quanto às tecnologias e materiais que eles poderiam utilizar para aumentar o interesse dos estudantes. Uma constante dificuldade dos professores de Engenharia de Requisitos é a preparação de aulas interativas, pois esta disciplina demanda a internalização de conceitos que geralmente são expostos em forma massivamente teórica, o que pode causar o desinteresse dos estudantes por esta disciplina. O objetivo deste trabalho é propor um repositório que possui um sistema de recomendações que apoie o professor de Engenharia de Requisitos a identificar os jogos mais adequados para utilização em sua sala de aula, de acordo com as suas necessidades e recursos disponíveis ao professor. Para isso será elaborado um ambiente inteligente, alimentado por professores de Engenharia de Requisitos com jogos para apoiar práticas educacionais, onde os professores poderão avaliar cada jogo publicado no sistema, bem como escrever sugestões para seu uso. Nesta tese, serão realizados diversos estudos, como Estudos de Caso, Revisões de Literatura e avaliação de protótipos, entre outros, para entender as demandas dos professores, propor um sistema de acordo com suas necessidades e avaliar sua eficiência no apoio aos professores. A maior contribuição esperada ao final desta pesquisa é um repositório inteligente sobre o uso de jogos nas disciplinas de Engenharia de Requisitos, que irá providenciar os jogos mais recomendados para o professor de forma inteligente.
Modelo para Caracterização e Evolução de Sistemas com Arquitetura Baseada em Serviços
Authors: Rosa Thatiane De Oliveira , Goldman Alfredo , Guerra Eduardo Martins
Published: April 2021

Construir uma boa arquitetura é fundamental para obter sucesso no processo de desenvolvimento de software . Porém, essa não é uma atividade trivial, pois envolve uma série de decisões de domínio do negócio, técnicas e de estrutura. Assim, com a finalidade de apoiar a construção de uma arquitetura mais adequada a um determinado contexto, constantemente surgem novas abordagens como microsserviços e monolitos modulares, que propõem decompor um software complexo em pequenas partes fracamente acopladas. Entretanto, ao analisar o estado da arte e da prática, percebe-se que existe um limite nebuloso na classificação dessas diferentes abordagens, especialmente as baseadas em serviços. Além de existir pouco suporte para caracterizar e direcionar arquiteturas baseadas em serviços. Diante disso, com base em pesquisas bibliográficas e estudos de caso, pretende-se desenvolver um modelo para caracterização e evolução da arquitetura de sistemas baseados em serviços, adotando diretrizes de microsserviços. Esse modelo apresenta dimensões que medem características estruturais da arquitetura relacionadas ao tamanho de módulos, compartilhamento de bases de dados e acoplamento entre serviços. Como contribuição final, esse modelo facilitará o mapeamento e medição de diferentes impactos gerados na arquitetura de software , a partir de incrementos e refatorações realizados. Assim como dará suporte a decisões arquiteturais que considerem diferentes atributos de qualidade para alcançar o equilíbrio entre independência e colaboração de serviços para um determinado sistema.

Authors: Ferreira Leite Leonardo Alexandre , Kon Fabio , Meirelles Paulo
Published: April 2021

In this research, we aim to understand the organizational structures adopted by software-producing organizations for managing IT technical teams in a continuous delivery context. Following Grounded Theory guidelines, we interviewed 46 IT professionals to investigate how organizations pursuing continuous delivery organize their development and operations teams. Among our results, we discovered four organizational structures: (1) siloed departments, (2) classical DevOps, (3) cross-functional teams, and (4) platform teams. After having discovered such structures and their properties, we describe, in this paper, our plans to better understand which contextual properties and forces lead an organization to adopt an organizational structure to the detriment of the other ones.
Uma Abordagem Visual para Evolução de Test Smells em Sistemas de Software Java
Authors: Cruz Adriana , Costa Heitor
Published: April 2021

O teste de software é parte do desenvolvimento de software. Durante o teste, podem surgir más escolhas de implementação do código de teste, levando a inserção de Test Smells. A presença de Test Smells em código de teste pode o tornar ineficaz em encontrar bugs, gerando retrabalho e custos adicionais. A manutenção do código de teste ocorre por causa da evolução do código de produção. Para visualizar a evolução de sistemas de software, têm sido utilizadas técnicas de visualização de software. Apesar dessas técnicas contribuírem para visualizar a evolução de sistemas de software, elas não abrangem código de teste para visualização de Test Smells. Dessa forma, no trabalho de mestrado, o objetivo é proporcionar melhor entendimento das ocorrências de Test Smells e sua evolução em código de teste aos Gerentes de Testes/Testadores, para agilizar a identificação de problemas nos casos de testes, melhorando sua qualidade. Para isso, será elaborada uma abordagem para visualizar essa evolução.
Uma Ontologia de Apoio ao Ensino de Experimentação em Engenharia de Software
Authors: Luz Carlos Danilo , OliveiraJr Edson , Steinmacher Igor
Published: April 2021

O uso de experimentação para avaliação empírica das atividades de desenvolvimento de software é uma prática comum nos dias de hoje. Tanto para a indústria de software como em pesquisas acadêmicas, a experimentação se mostra fundamental para a compreensão do ciclo de vida de um software, considerando um conjunto de atividades sistemáticas apoiadas por técnicas estatísticas. Por mais que a comunidade científica de Engenharia de Software (ES) venha utilizando experimentação para a avaliação de teorias e tecnologias, ainda há carência de metodologias e materiais de ensino específicos para experimentação em ES (ESE), o que, consequentemente, ameaça o planejamento, a condução e a disseminação adequada de experimentos e suas futuras reproduções. Assim, esta pesquisa tem como objetivo especificar uma ontologia de apoio ao ensino de experimentação em ES, considerando o desenvolvimento, uso e reúso de Recursos Educacionais Abertos (REA). Tal ontologia será capaz de formalizar os conceitos de ensino de ESE e REAs, além de contribuir com a comunidade de ES na produção e disseminação de materiais de ensino e aprendizagem.
Using predictive models to evaluate the quality of a test suite at class and method level.
Authors: Silva Keslley Lima , Cota Érika
Published: April 2021

Testing is an indispensable part of the software development process and is a continuous process during the development life cycle. In this context, examining the behavior of software systems to reveal potential problems is a crucial task. To this end, the test suites usually are utilized to examine the software quality. However, test suite quality control is hard for the tester, especially in an evolving system. Such control is needed to assure and improve the test suite's quality and the application as a consequence. Currently, test coverage criteria are used as a mechanism to assist the tester in analyzing the test suite (e.g., find the weaknesses, and add a new test case or test inputs). However, more strong coverage criteria (potentially showing less glaring weaknesses) are challenging to assess. In this work, we propose a different approach to support the developer in evaluating the test suite quality based on more powerful test coverage criteria. We will follow the Knowledge Discovery in Database process using machine learning algorithms to estimate the prime path coverage at the method and class level. For this purpose, we will create two large datasets consisting of source code metrics and test case metrics from 12 open-source Java projects, and these datasets will be used in the training process to build the predictive models. Using the built models, we expected to predict the prime path coverage at the method and class level with a reliable prediction performance.
Técnicas Computacionais de Alto Desempenho na manipulação de Malhas de Elementos Finitos
Authors: Silva Guilherme M. F. , Camata José J.
Published: April 2021

Diversos fenômenos físicos e/ou problemas da Engenharia e ciências são modelados por equações diferenciais parciais. Essas equações podem ser solucionadas através de métodos numéricos, tais como, diferenças finitas, elementos finitos e volumes finitos. Em comum, esses métodos requerem alguma forma de discretização de domínio do problema, ou seja, determinar pontos específicos do domínio onde a solução da equação diferencial será calculada. Essa discretização pode ser baseada em gradeamento cartesiano (diferenças finitas) ou através de subdivisões do domínio em elementos discretos (elementos e volume finitos). Neste trabalho, focaremos em discretizações (malhas) específicas para o método de elementos finitos e o desenvolvimento de técnicas para manipulação de malhas voltadas para a computação de alto desempenho.

Authors: Lima Luan , Uchôa Anderson , Bezerra Carla , Coutinho Emanuel , Rocha Lincoln
Published: April 2021

This paper presents data visualizations obtained from the application of 15 measures used to support the maintainability evaluation of Software Product Line (SPL) and Dynamic SPL (DSPL) Feature Models (FMs). To identify these visualizations, we applied a survey to classify a set of 40 measures for evaluating the (D)SPL FMs maintainability. Five visualizations were designed from this classification to analyze the extensibility, static variability, dynamic variability, and structural complexity of the FMs. As result, the experts concluded the designed visualizations assist in FMs maintainability interpretation.
Minnesota Experimental City, oder: Zukunft als Experiment – Minnesota Experimental City, or: Future as Experiment
Authors: Gellai Szilvia
Published: April 2021

Der Beitrag stellt das nie gebaute US-amerikanische Planstadt-Projekt Minnesota Experimental City vor, das zwischen 1966 und 1973 unter der Federführung des Geophysikers Athelstan Spilhaus und des Zeitungsverlegers Otto Silha vorangetrieben wurde. Ziel des Projekts war es, einen universellen Prototyp für die Lösung urbaner Probleme zu entwickeln. Umweltverschmutzung wurde unter diesen Problemen als zentral erachtet, weshalb die Kontrolle der städtischen Umgebung mittels neuester (Computer-)Technologien von vornherein in die Stadtkonzeption implementiert wurde. Wie der Aufsatz zeigt, korreliert das Verständnis der Stadt als geschlossenes Ökosystem mit ihrer Konzeptualisierung als einer Maschine der Datenerhebung. Für die historische Einbettung des Projekts werden zunächst zeitgenössische ingenieurtechnische Kuppelstadtdiskurse skizziert. Überleitend wird das Denken von Spilhaus als einem im deutschsprachigen Raum kaum bekannten Akteur an der Schnittstelle zwischen Naturwissenschaften, Technologiesektor und Wissenschaftspopularisierung beleuchtet. Die Betrachtung der Genealogie der Experimentalstadt wird durchweg medientheoretisch saturiert und die MXC als ein Kapitel kybernetisch-systemtheoretischen Denkens in der Geschichte stadtplanerischer Imaginationen und ingenieurtechnischer Praktiken konturiert. Aufgrund seines experimentellen Charakters und seiner spezifischen Temporalität kann das Projekt als Vorläufer des heutigen Testbed-Urbanismus (Halpern et al.) betrachtet werden.
Die Zukunft vorstellen – Technologie-Demonstrationen in der Geschichte digitaler Medien – Imagining the Future – Technology Demonstrations in the History of Digital Media
Authors: Ernst Christoph , Schröter Jens
Published: April 2021

Der vorliegende Text widmet sich der Bedeutung von Technologie-Demonstrationen in der Geschichte digitaler Medien. Diese werden als performative Praktiken betrachtet, in denen die Zukunft einer Technologie im Fokus steht. Unter Bezug auf einschlägige sozialwissenschaftliche Forschung diskutiert der Text die Rolle sogenannter imaginaries im Rahmen von Technologie-Demonstrationen. Diese theoretische Schwerpunktsetzung wird im Folgenden auf die Geschichte der Technologie-Demonstration im Bereich digitaler Medientechnologien bezogen. Aufbauend auf dem Gedanken, das speziell die Demonstration von User-Interfaces als Anker für die Mobilisierung von Imaginationen rund um die Zukunft digitaler Technologien dient, sichtet der Text drei Fallbeispiele: 1. die Präsentation des ‚oN-Line-System (NLS)‘ am

9. Dezember 1968 durch Douglas Engelbart; 2. die 100-tägige Demonstration des interaktiven Fernsehens Piazza virtuale während der documenta IX im Sommer 1992 durch die Medienkünstlergruppe Van Gogh-TV; 3. die Keynote-Präsentation des damaligen Apple CEO Steve Jobs anlässlich der Markteinführung des ersten iPhones am 9. Januar 2007. Anhand dieser teils kanonischen, teils vergessenen Beispiele zeigt sich die Bedeutung von Technologie-Demonstrationen für die soziale Vermittlung von neuen Technologien. Der Text schließt mit dem Argument, dass die Geschichte der Imagination digitaler Medien, wie sie in diesen Demonstrationen exemplarisch analysierbar wird, als ein integraler Bestandteil der Geschichte digitaler Medientechnologien generell zu betrachten ist.

Factorial models of Rosenberg’s Self-esteem Scale in Peruvian adolescentsAbstract: The Rosenberg Self-Esteem Scale (RSE) is an instrument widely used and designed to measure self-esteem in a single dimension. The aim of this research was to analyze the internal structure and the reliability of the RSE in Peruvian adolescents. The scale was administered to a total of 715 adolescents (51.3% female) with an average age of 12.20 years. Six models were identified by confirmatory factor analysis, which correspond to factorial structures reported in previous studies. The results showed a better goodness of fit for the one-dimensional model with control of method effects on inverse items, eliminating item 8 due to its ambiguity. Reliability was adequate and was calculated using the omega coefficient. The unifactorial structure of the RSE is discussed and it is concluded that the instrument reports evidence of validity and adequate internal consistency to be used in the Peruvian context.Keywords: Self-esteem; teenagers; validity; reliability.Resumen: La Escala de Autoestima de Rosenberg (RSE) es un instrumento ampliamente utilizado que fue diseñado para medir la autoestima en una sola dimensión.

Self-esteem, self-compassion and positive and negative affect in victims and bullies: A comparative study with self-report and peer-report measuresAbstract: Bullying is a prevalent problem with numerous negative consequences in psychological adjustment, especially for victims. However, most research on the topic is based on self-report measures subject to several biases and other limitations. The present study assessed self-esteem, positive and negative affect and self-compassion in 649 adolescents classified into victims, bullies, bully-victims and not involved students through peer- and self-report measures. Results showed that considering oneself a bully or a victim was associated with the psychological outcomes, being so in peer-report measures. Also, in selfreport measures, not involved participants showed higher levels of self-compassion than the other groups. The present research highlights the importance of including self-report and peer-report measures of bullying when studying the psychological adjustment of victims and bullies.Keywords: Self-compassion; bullying; self-esteem; adolescence; affect; self-report; peer-report.Resumen: El bullying es un problema altamente prevalente con numerosas consecuencias negativas sobre el ajuste psicológico, especialmente para las víctimas. Sin embargo, la mayoría de las investigaciones están basadas en autoinformes que están sujetos a diversos sesgos. La presente investigación evaluó la autoestima, el afecto positivo y negativo y la autocompasión de 649 adolescentes clasificados como víctimas, agresores, agresores-víctimas o no implicados utilizando medidas auto- y heteroinformadas por los compañeros. Los resultados mostraron que autorreconocerse como agresor o víctima guardó una asociación con las medidas de ajuste analizadas, más allá de serlo en las medidas heteroinformadas. En las medidas autoinformadas los participantes no implicados mostraron mayores niveles de autocompasión que los otros grupos. Se resalta la importancia de utilizar de manera conjunta medidas autoinformadas y heteroinformadas para estudiar variables relacionadas con el ajuste psicológico de víctimas y agresores.Palabras clave: Autocompasión; bullying; autoestima; adolescencia; afecto; autoinforme; informe de pares.

Towards Conceptual History of Management: The Language of the 1950s Textbooks in Finland
Authors:   Aalto University School of Business, Peltonen Tuomo
Published: April 2021

Purpose: The purpose of this article is to add to the emerging body of conceptual histories of management by undertaking a reading of three leading Finnish textbooks from the 1950s. Design: Management concepts are analysed through the linguistic dynamics of a set of historically situated Finnish textbooks. The semantic dimension of analysis is concerned with the conceptual structures behind particular linguistic constructions. The pragmatic dimension, on the other hand, is attuned to the speech act aspects of conceptual formations. Findings: The analysis shows that the current concept used for “management” in Finnish does not feature as the key word in the 1950s textbook articulations. Instead, concepts such as “business caretaking”, “administration”, “arranging” or “education” are employed to signify the reality of organizational and managerial structures and processes. Furthermore, the texts strove to legitimize management mainly in terms of the moral character of managers and the management process. Research implications: Conceptual histories of linguistically non-English contexts offer interesting contrasts to the dominant Anglo-American discourses of management and related phenomena. More empirical studies of conceptual history of management are needed. Originality: This article adds to the limited body of empirical investigations of conceptual history of management, organization and related issues.
Micronutrient intervention effects on cognitive outcomes in post-acute traumatic brain injury
Authors:   , Denniss Rebecca J
Published: April 2021

Traumatic brain injuries result in a complex pathophysiological cascade that includes neuroinflammation, cellular energy dysregulation and axonal injury (Werner & Engelhard, 2007). Nineteen essential vitamins and minerals, along with omega-3 polyunsaturated fatty acids, are required by the body for competent cellular function. These cannot be synthesized by the body and must therefore be ingested either as part of the diet or through supplementation. Previous research has highlighted a relationship between micronutrient (vitamins, minerals, omega-3) levels and cognition in a range of neurological conditions (Bitarafan et al., 2014; Moore et al., 2012; Veronese et al., 2016), however there is very little research in post-acute traumatic brain injury (TBI). The aims of this thesis were to investigate the effects of micronutrient supplementation on cognition in both a normative and a TBI population, while also gaining an insight into the levels of micronutrients present in the diets of these participants. In the TBI population the hypothesis was that by nutritionally supporting these individuals this would improve cellular functioning and neuronal repair following injury, reducing the effects of ongoing secondary cascade mechanisms, with improved cognitive function as the outcome. Study one (normative study) demonstrated significant improvements in cognition, specifically memory and executive functions, following a relatively short eight-week intervention period, particularly in those taking a broad-spectrum multimicronutrient. Study two (TBI population) used a cross-over study design (omega-3 and multimicronutrient) with parallel placebo group. The omega-3 intervention consistently resulted in improved learning, attention, processing speed and set shifting, whereas improvements following the multimicronutrient intervention were more limited. Analyses of food diaries from participants in both studies indicated that levels of fat-soluble vitamins, some B vitamins, and minerals are below recommended intake in diet. Results of these studies indicate that micronutrient interventions can result in cognitive improvement in a relatively short period of time. This evidence provides a solid foundation for future micronutrient research in TBI populations which have the potential to serve as an adjunct to traditional rehabilitation strategies.
"A Regiment of Skeletons and an Army of Bottles": Reading the Hunterian Museum in Nineteenth-Century Scientific and Popular Culture
Authors: Burke Verity
Published: April 2021

Closely associated with, and used as a demonstration of the professionalization of medicine, anatomy museums and the bodies they displayed were troubled by associations ranging from the outmoded cabinet of curiosity to quackery. The myriad publications produced by educational anatomy museums foregrounded an ambition to make museums a scientific space, and the human and animal body a scientific subject through material and textual ordering. They intended to educate by placing objects in series that told a specific story, by taxonomising and cataloguing, lecturing and labelling, pinning knowledge both to the body’s material form, and the texts that illuminated it. This use of narrative was not a one-way adoption of literary techniques to legitimize institutions; literary culture frequently borrowed the ordering principles of the museum, mediating both the popular understanding of museum spaces, and the potentially sensational representation of bodies in reportage and fiction. This paper reads the catalogues, guidebooks and specimen representations of the Hunterian Museum in the Royal College of Surgeons, England, alongside its representation in Charles Dickens’s popular periodical Household Words to consider how knowledge is hermeneutically constructed, legitimizing anatomical intermediality and the museum project.
Ann Yearsley, Earl Goodwin, and the Politics of Romantic Discontent
Authors: Foss Chris
Published: April 2021

There is a dearth of more substantial critical studies on Ann Yearsley’s tragic drama Earl Goodwin in general, and while the few out there have helpfully illuminated the play’s representation of the historical plight of women and the poor during Anglo-Saxon times, as well as its application to their current predicaments in Romantic-era England and France, they have tended to leave unexplored the ways in which Yearsley simultaneously is clarifying and extending her anger at and frustration with the class- and gender-based discrimination she experienced firsthand in the fallout with her mentor Hannah More over the profits from her first book. This article aims to fill this gap by delineating the many ways in which Earl Goodwin represents, on one level, her ongoing response to the defamation she suffered in the wake of More’s public campaign to ruin her reputation. Documenting the inextricability of the play’s explicit social and political critiques with Yearsley’s ongoing response to the More fiasco should in fact reinforce the extent to which her more familiar initial reactions are as fundamentally politically as they are personally motivated. Earl Goodwin offers readers a positive example of how to respond to abuses of power without resorting to revenge while still actively resisting, always refusing to airbrush the inequities she and others like her (women, the poor, and especially working-class women) continue to face day in and day out, enduring insult and injustice, but remaining undaunted in the commitment to the cause of beneficial social change.
“The Penance of Life”: The Testimonial Paradigm in Coleridge’s The Rime of the Ancient Mariner
Authors: Wright Jude
Published: April 2021

This article argues that The Rime of the Ancient Mariner’s curious and much commented on theology is best accounted for by examining it in relation to a shift in religious discourses. The poem evidences a disconcerting shift from a Catholic confessional dynamic to one closer akin to an Evangelical paradigm of testimony. As such, the article begins by accounting for the importance of testimony (and its theological logic) in the Evangelical milieu which spread across Britain during Coleridge’s early to middle years. It next examines Coleridge’s developing religious thought in relation to Evangelical concepts, pointing to the significance of what J. Robert Bart termed a “balance” between “man’s work and God’s work in the process of faith; man’s will and God’s will; rational argumentation and divinely granted revelation; objective evidence and subjective religious experience.” Upon situating Coleridge in relation to Evangelical concepts of witnessing, the article more fully examines The Rime of the Ancient Mariner, focusing on the shift in theological logic that changes a kind of Catholic confessional impulse towards an on-going urge to testimony, finally linking the burning feeling that compels the Mariner’s testimony to the Pentecost event as related in the New Testament book of Acts.
Constructing Victimhood: Storied Opposition to Legislation Protecting LGBTQ Students
Authors: Lai Daniel , Presser Lois , Schally Jennifer L.
Published: April 2021

Contemporary initiatives against anti-LGBTQ bullying in the United States include enumeration policies, which name sexual orientation as an unacceptable basis for bullying. Conservative opposition to these and other initiatives has been swift, taking discursive and specifically narrative form. This article examines how opponents of prevention and intervention use narrative to resist efforts to curb anti-LGBTQ bullying, based on analysis of 22 public statements challenging anti-bullying legislation. They deny anti-LGBTQ bullying’s impact and reassign victimizer and victim positions. Achieving justice for anti-LGBTQ bullying victims requires recognition of the stories that uphold heteronormative power.
Self-Narrative Elicitation in Counseling: An Exploration of the Usefulness of Selected Interview Methods
Authors: Soroko Emilia
Published: April 2021

An important element of many forms of counseling is the narrative articulation of the client experience. This article aims to define self-narrative elicitation methods, to explore their use in counseling, and to present a quantitative empirical examination of narrative interview instructions. It examines whether the self-narrative inclination and selected situational factors influence the narrativity level of the utterances when elicited by different types of self-narrative instructions. The results show that the utterances produced by three different types of instructions (open-ended question; photo-elicitation; life-as-book metaphor) do not differ in narrativity level. The narrativity of utterances measured micro-analytically on the lexical level remains independent from the external factors (sequence, topic, type of instruction). Given the level of narrativity and length of response, the three instructions are close to each other. At the same time the narrativity is significantly influenced by self-narrative inclination. It is worth acknowledging personal features that can change the way the story is told in interviews and thus affect the counseling practice.
“It’s impossible that there’s no connection”
Authors: Baum Miri Tashma
Published: April 2021

Despite the growing interest in language learning histories, autobiographical reasoning, a central concept in narrative psychology, has rarely appeared in second language acquisition research, despite the fact that autobiographical reasoning has been found to be central to identity formation, correlating with resilience, motivation, and well-being. This article conducts a narrative analysis of the language learning histories of two English as a foreign language (EFL) student teachers, focusing on three qualities of their autobiographical reasoning: integration, valence, and vividness. It shows how differences in their autobiographical reasoning correlate with differences in their motivation and confidence. It also argues that production of language learning histories can contribute to the development of more confident and motivated learners and teachers.
Play and Possibility
Authors: Tynan Avril
Published: April 2021

Cultural representations of Alzheimer’s disease typically focus on the social and emotional burdens felt by family and friends, diluting or excluding the experience of the sufferer. This article demonstrates how narrative fiction may help us to engage with the experiences of individuals with Alzheimer’s disease by imagining what it might be like to suffer from the disease ourselves. Demonstrating the humanized and subjective understanding of Alzheimer’s disease articulated in Olivia Rosenthal’s (2007) On n’est pas là pour disparaître [We’re Not Here to Disappear (2015)] this article also exposes the limitations of narrative fiction as a means of highlighting our own ignorance in the face of others’ experiences.
The End of the Story? Narrative Openness in Life and Death
Authors: Randall William
Published: April 2021

In this 2019 John McKendy Memorial Lecture,1 Dr. William Randall discussed how few topics intrigue us more than death. Yet few topics are more taboo—not unlike aging, with which, in many people’s minds, it can seem synonymous. But just as a narrative perspective on aging enables us to envision its more positive potentials in terms of meaning, wisdom, and spirituality, so a narrative perspective can shed a more redemptive light on death, presumably the final event in the story of our lives. Drawing on insights from psychology, gerontology, cosmology, theology, and literary theory, Dr. Randall used the concept of narrative openness to entertain alternative and ultimately enticing ways of storying the so-called end of life.

Multi-variable quaternionic spectral analysis
Authors: Cho Ilwoo , Jorgensen Palle E.T.
Published: April 2021

In this paper, we consider finite dimensional vector spaces \(\mathbb{H}^n\) over the ring \(\mathbb{H}\) of all quaternions. In particular, we are interested in certain functions acting on \(\mathbb{H}^n\), and corresponding functional equations. Our main results show that (i) all quaternions of \(\mathbb{H}\) are classified by the spectra of their realizations under representation, (ii) all vectors of \(\mathbb{H}^n\) are classified by a canonical extended setting of (i), and (iii) the usual spectral analysis on the matricial ring \(M_n(\mathbb{C})\) of all \((n \times n)\)-matrices over the complex numbers \(\mathbb{C}\) has close connections with certain "non-linear" functional equations on \(\mathbb{H}^n\) up to the classification of (ii).

Authors: Gil' Michael
Published: April 2021

Let \(A\) and \(\tilde{A}\) be bounded operators in a Hilbert space. We consider the following problem: let the spectrum of \(A\) lie in some strip. In what strip the spectrum of \(\tilde{A}\) lies if \(A\) and \(\tilde{A}\) are "close"? Applications of the obtained results to integral operators and matrices are also discussed. In addition, we apply our perturbation results to approximate the spectral strip of a Hilbert-Schmidt operator by the spectral strips of finite matrices.

Apoptosis is characterized by profound morphological changes, but their physiological purpose is unknown. To characterize the role of apoptotic cell contraction, ROCK1 was rendered caspase non-cleavable (ROCK1nc) by mutating aspartate 1113, which revealed that ROCK1 cleavage was necessary for forceful contraction and membrane blebbing. When homozygous ROCK1nc mice were treated with the liver-selective apoptotic stimulus of diethylnitrosamine, ROCK1nc mice had more profound liver damage with greater neutrophil infiltration than wild-type mice. Inhibition of the damage-associated molecular pattern protein HMGB1 or signalling by its cognate receptor TLR4 lowered neutrophil infiltration and reduced liver damage. ROCK1nc mice also developed fewer diethylnitrosamine-induced hepatocellular carcinoma (HCC) tumours, while HMGB1 inhibition increased HCC tumour numbers. Thus, ROCK1 activation and consequent cell contraction are required to limit sterile inflammation and damage amplification following tissue-scale cell death. Additionally, these findings reveal a previously unappreciated role for acute sterile inflammation as an efficient tumour-suppressive mechanism.

Natural mortality (M) is defined as the rate of loss that occurs in a fish stock due to natural (non-fishing) causes and can be influenced by density-dependent or density-independent factors. Different methods have been used to estimateM, one of these is the gnomonic approach. This method estimatesMrates by dividing the life cycle of a species into subunits of time that increase as a constant proportion of the time elapsed from birth up to the initiation of each subdivision. In this study, an improved gnomonic approach is proposed to estimate natural mortality throughout different life stages in marine stocks using thegnomonicMpackage written in R software. This package was built to require data about (i) the number of gnomonic intervals, (ii) egg stage duration, (iii) longevity, and (iv) fecundity. With this information, it is possible to estimate the duration and natural mortality (Mi) of each gnomonic interval. ThegnomonicMpackage uses a deterministic or stochastic approach, the latter of which assesses variability inMby assuming that the mean lifetime fecundity (MLF) is the main source of uncertainty. Additionally, thegnomonicMpackage allows the incorporation of auxiliary information related to the observed temporal durations of specific gnomonic intervals, which is useful for calibrating estimates ofMvectors. ThegnomonicMpackage, tested via deterministic and stochastic functions, was supported by the reproducibility and verification of the results obtained from different reports, thus guaranteeing its functionality, applicability, and performance in estimatingMfor different ontogenetic developmental stages. Based on the biological information of Pacific chub mackerel (Scomber japonicus), we presented a new case study to provide a comprehensive guide to data collection to obtain results and explain the details of the application of thegnomonicMpackage and avoid its misuse. This package could provide an alternative approach for estimatingMand provide basic input data for ecological models, allowing the option of using estimates of variable natural mortality across different ages, mainly for life stages affected by fishing. The inputs for thegnomonicMpackages are composed of numbers, vectors, or characters depending on whether the deterministic or stochastic approach is used, making the package quick, flexible, and easy to use; this allows users to focus on obtaining and interpreting results rather than the calculation process.

The main objective of this research is to evaluate a new approach for the preparation of bio adhesive nanoparticles and to design an innovative topical delivery system for curcumin which is able to enhance the drug anticancer activity. Curcumin encapsulated nanoparticles were prepared by ionic gelation method. The nanoparticles were found to be discrete, spherical with free-flowing properties and evaluated for particle size analysis, shape (scanning electron microscopy), drug encapsulation efficiency, FTIR, DSC studies and in vitro release performance. The best selected nanoparticles formulation (FS5, containing drug: polymer ratio 1:5) was incorporated into gels with a bio adhesive polymer. The Nanoencapsulated topical gels were evaluated for pH, spreadability, extrudability, viscosity, in vitro drug release, drug release kinetics, bio adhesion test, accelerated stability of selected gel formulation. In vitro drug release rate for selected Nanoencapsulated bio adhesive topical gel (FS3 gel, containing 1 % w/w of drug loaded nanoparticles and 0.6 % w/w of Carbopol 934) was found to control curcumin release over 12h. The results were then compared statistically and obtained a satisfactory correlation. Thus, in conclusion preparation protocol of Nanoencapsulated topical gel study may be adopted for a successful delivery of Curcumin for topical use.

The main objective of this research is to evaluate a new approach for the preparation of bio adhesive microparticles and to design an innovative vaginal delivery system for curcumin which is able to enhance the drug anticancer activity. Curcumin encapsulated microspheres were prepared by solvent evaporation method. The microspheres were found to be discrete, spherical with free-flowing properties and evaluated for particle size analysis, shape (scanning electron microscopy), drug encapsulation efficiency, FTIR, DSC studies and in vitro release performance. The best selected microsphere formulation (F2, containing drug: polymer ratio 1:2) was incorporated into gels with a bio adhesive polymer. The microencapsulated vaginal gels were evaluated for pH, spreadability, extrudability, viscosity, in vitro drug release, drug release kinetics, bio adhesion test, accelerated stability of selected gel formulation. In vitro drug release rate for selected microencapsulated bio adhesive vaginal gel (FS3 gel, containing 1 % w/w of drug loaded microspheres and 0.6 % w/w of Carbopol 934) was found to sustain curcumin over 12h. The results were then compared statistically and obtained a satisfactory correlation. Thus, in conclusion preparation protocol of microencapsulated vaginal gel study may be adopted for a successful development of newer drug delivery system of other drugs for administration to vagina.
Sugar Transport in a Merging Phloem Vessels: A Hydrodynamic Model

Green plants are the major tappers of the energy from the sun. The collected solar energy in the form of light is used to activate the chemical reaction occurring in matured leaves between carbon dioxide and water, leading to the synthesis of sugar (chemical energy). Two main transport processes are involved in the transport of mineral salt water from the soil through the roots, via the trunk and branches to the leaves where photosynthetic activity occurs, and the translocation of sugar from the leaves to where they are needed and possibly, stored. The xylem vessels bear the absorbed mineral salt water while the phloem vessels bear the manufactured sugar. In this study, neglecting the effects of occlusion and clogging of the phloem channels, we investigate the transport of sugars in the merging phloem vessels using the hydrodynamic approach. The model is designed using the Boussinesq approximation and solved semi-analytically using the regular perturbation series expansion solutions and Mathematica 11.2 computational software. Expressions for the concentration, temperature, and velocity are obtained and presented quantitatively and graphically. The results show among others, that increase in the merging angle causes a reduction in the concentration, temperature, and velocity profiles. However, there exists fluctuations in the concentration and temperature structures.
