Published: September 2022

A 28 year-old female with congenital human immunodeficiency virus infection presented with microangiopathic hemolytic anemia and thrombocytopenia secondary to multi-drug resistant Pseudomonas aeruginosa pulmonary infection. Initial management for thrombotic thrombocytopenic purpura (TTP) was discontinued when normal ADAMTS13 activity was found. There are several infectious etiologies that can exhibit microangiopathic hemolytic anemia and thrombocytopenia mimicking TTP including P. aeruginosa. This case highlights the importance of following guidelines regarding dual antibiotic coverage for P. aeruginosa infection as antibiotic resistance can develop during the course of treatment.
Theodicy and the Historical Adam: Questioning a Central Assumption Motivating Historicist Readings
Authors: Franklin Patrick S.
Published: September 2022

In this article, I aim to show, first, that theodicy tends to be a major motivating factor grounding biblical-theological arguments in favor of historicity; and second, that a historical Adam/Fall fails to address adequately the questions theodicy raises. I do not argue here for or against the historicity of Adam; nor do I seek to offer a new theodicy. My intended contribution is more modest: to critique the strong impact that theodicy has on the question of the historicity of Adam/the Fall and to open space for nonhistorical interpretations. I conclude by commending Dietrich Bonhoeffer‚Äôs exposition of Genesis¬†1‚Äì3 as theologically fruitful.
Science and Theology as Gifts to the Church: How Creation Allows Scientists and Theologians to Work Together
Authors: Jaeger Lydia
Published: September 2022

In contrast to common practice, which separates science and theology, this article takes the doctrine of creation as the key to map out fruitful interactions between science and theology. In particular, it asks how theologians---and the wider church---can benefit from science and what scientists can learn from theology for their professional work. Such an integrated view enables us to understand science as a gift to the church and also to consciously take advantage of theological resources in scientific practice. Although this article mainly uses creation as the lens through which to address these questions, it also hints at contributions which the doctrines of sin and redemption offer.
Reflective Practice and Faith Integration: An Example from Psychology That Can Be Applied Across Disciplines
Authors: Baucke Camden L. , Seifert Lauren S.
Published: September 2022

Although faith integration has been part of Christian ministry and pastoral counseling, it has not been included as much in clinical research, training, and practice in psychology, secular counseling, or most health professions. Reasons for exclusion include secular ethics and licensing criteria, but Christian faith can inform research and professional practice--even in secular contexts. Previous authors have discussed the integration of faith with medical practice: in some settings, using providential intervention; and in eldercare, using religious coping. This article extends that work to consider faith integration with reflective practice. Sacrifice of one's own perspective to peer inside the worldview of another, for the sake of healing, not only provides pragmatic improvements to care, but also correlates with God's commandments to love one another. Relevant techniques of reflective practice increase the quality of care given by all healthcare professionals. Many faith-integration techniques presented in this article can be applied to disciplines across the arts, sciences, and humanities.
The Design of Noah’s Ark and Its Significance for Biblical Faith
Authors: Dickin Alan
Published: September 2022

This article reexamines the design of Noah's ark based on a combination of biblical and Mesopotamian sources. Although the biblical description of Noah's ark is considered to be divinely inspired, it seems questionable whether it could have been built to the size and design that is popularly conceived. The Genesis account lacks detail about the method of construction, but since it shows evidence of a common source with ancient Mesopotamian versions, these can provide additional information to constrain our interpretation of the Bible. For example, the very large amounts of bitumen specified in the Mesopotamian sources suggest that this was used as a structural component, to reinforce a raft-like ark and create a smooth and durable platform for large numbers of animals. On this platform, a reed-built hut could have been securely fastened to provide a dry shelter for human habitation and food storage; that being the case, and using readily available materials, it was possible to construct a large and sea-worthy ark of the dimensions specified in Genesis, using primitive ancient tools.
From One Person? Exegetical Alternatives to a Monogenetic Reading of Acts 17:26
Authors: Horst William
Published: September 2022

Biblical scholars and theologians who defend the classical view that Adam and Eve are the sole progenitors of humanity typically appeal to Acts 17:26 as a key proof text. This verse is part of Paul’s speech in Athens, and is usually translated to say something like, "from one ancestor [God] made every human nation to dwell upon the entire face of the earth"; in this instance ancestor is normally understood to be Adam. This article surveys several alternative exegetical analyses of the passage that do not suggest that humanity descended from one single couple, and compares the considerations that weigh in favor of and against each plausible option. Ultimately, it is argued that the Christian tradition of the unity of truth suggests that faithful interpreters of Acts may opt to favor those plausible interpretations that align with the scientific consensus of polygenism over those that imply monogenism.

On the use of teaching aids at the College of Education Portorož–Koper (1947–1968)
Authors: Kontestabile Mirjana , Lepičnik Vodopivec Jurka
Published: September 2022

In the past and still today, teaching aids have played an important role in providing future teachers with quality education. Their use in schools was affected by different historical contexts of education, school regulations as well as the development of industry, science, and didactics. After the Second World War, the use of a variety of media, such as tape recorder, radio, episcope, and slide projector, spread with electrification. As can be gathered from its well-equipped cabinet, the Imperial-Royal College of Education for Men in Koper (1875–1909) devoted much attention to teaching aids, especially in physics instruction. On its establishment after the Second World War, the college of education for southern Littoral, first opened in Portorož, also provided teaching aids, collections of teaching aids, and educational technology. In the absence of continued tradition, the college faced a lack of teaching aids. At the end of the 1950s, increasingly less teaching aids were bought as colleges of education converted into high schools of education sciences.

Published: September 2022

Human biological processes are heavily influenced by nervous system and it interacts in physiological processes, such as cognition and individual cell function therefore; injury of the peripheral or central nervous system (PNS or CNS) causes loss of sensory and motor functions, affecting the patients’ quality of life. The regeneration capability of the human adult nervous system is often limited, and its recovery is difficult due to the complex physiology system and limited regenerative capacity. Tissue engineering is a novel clinical treatment field utilizing a blend of polymeric scaffolds and cells, representing a promising methodology for nerve recovery. The engineered materials and the fabricated neural scaffolds have gained expanding consideration in the field of nerve repairs. Nerve scaffolds surpass autologous nerve grafts in terms of implantation rate and outcome. Additionally, they foster a conducive cellular environment enabling axonal proliferation, neurite extension and connection, and neural cell survivability, adhesion, and migration. Due to their exceptional chemical and physical capabilities, numerous natural and manmade polymeric materials have been preferentially used during neural scaffolds to date. This review article presents various natural and synthetic polymers being used in neural tissue engineering, along with their benefits and challenges for neural recovery.

Published: September 2022

Due to the vulnerability of the Sombriero River to contaminants, the effect of seasonal variation on the physico-chemical characteristics of the Sombriero River was investigated with respect to its sediment and surface water samples to ascertain the degree of alterations from the natural background level of the river and adherence to regulatory standards. Surface water and sediments were collected at seven selected sites along the Sombriero River. The dry season sampling was carried out in December, 2020, while the wet season sampling took place in May, 2021. The samples were analyzed in the laboratory following standard operational procedures. The results indicated high alterations (p< 0.05) in the concentrations of cadmium, nickel, zinc, iron, total dissolved solids, turbidity, biochemical oxygen demand, and chemical oxygen demand, beyond the background values of Nigeria’s Department of Petroleum Resources (DPR) and Federal Ministry of Environment (FMENV). The majority of the heavy metals, notably copper, cadmium, lead, manganese, nickel, zinc, and iron, had higher concentrations in water during the dry season, while sodium, potassium, and magnesium showed an increase in concentration in surface water during the wet season. However, the pH level was within the target background values of DPR and FMENV, and showed no significant variation in the dry and wet seasons. For instance, surface water had a pH range of 6.65 –7.18 in the wet season, and 6.93 –7.18 in the dry season. Sediments ranged from 6.06 – 6.59 and 6.10 – 6.88 during the wet season and dry season, respectively. The quality of water influences the health status of any populace, hence, analysis of water for physical, chemical, and biological properties is very important.

In addition, policymakers and other business practitioners should ensure that entrepreneurial activities in terms of achievement orientation and learning orientation are utilized to improve the innovativeness in their respective managerial levels.
Validity and Reliability: The Functionality of Knowledge Seeking Behaviour and Theory Building
Authors: Prince Alamina Ule , Friday Ogbu Edeh , Wapaimi Aberes , Woyengiimomoemi Jacob Micah
Published: September 2022

The scientific approach to knowledge generation hinges in the collection of valid and reliable data about the phenomenon being investigated. These quests for knowledge claims not only satisfy the human curiosity in the need to know but also emphasize the systematic application of science in the investigation of social phenomenon. However, the functionality of knowledge seeking behaviour rests on the sustenance of the human quest for valid and reliable knowledge. These knowledge only become meaningful when they stand to explain the purpose, nature, meaning and shortfalls of the human element which is the centre of inquiry in the behavioural science research. Thus, an understanding of this phenomenon gives insightful knowledge into the kind of data to be collected that would aid in theory building which is the tool for explaining the knowledge that researchers anchors their philosophical assumptions upon. And since theory building in the behavioural science domain requires the collection of accurate and reliable data in order to make salient epistemic claims and generalization, researchers need to uncover the phenomenon under investigation and such understanding must be taken into consideration. These considerations would inform researchers on the approach to be adopted. Based on these the paper concluded that researchers need to understand the human ontological nature which gives rise to epistemological consideration because human behavior is unpredictable.
The English Judicial Trends in Lifting the Corporate Veil
Authors: Khokhar Farqaleet
Published: September 2022

The “separate legal personality” and “limited liability” are two main and fundamental principles of corporate law. The concept of a separate legal personality of the company originated from the case Salomon v Salomon & Co Ltd. The landmark case decided that when a company is registered, it attains a separate legal identity. A corporate veil is a concept that recognizes the separate corporate personality of the company from the shareholders‟ personalities. In many circumstances, it happens that the corporate personality of the company commits fraud or any other illegal acts. It becomes impossible to believe that an artificial personality like a company commits any illegal act or fraud. In such cases, for the identification of the original wrongdoer, the veil of the corporation is pierced which is also called lifting the corporate veil. To highlight the English Courts’ trends in lifting the corporate veil, this article unearths the canons of English courts’ judgments to pinpoint the inconsistencies in their decisions. The paper inspects the exceptions to the Saloman rule that have been focused on and meticulously analysed in this research paper to highlight the evolution of these recognised exceptions including “Single Economic Entity, Fraud, and Facade, Sake of justice, and Agency.”
Measuring the Impact of Social Responsibility on the Effectiveness of the Mandatory International Financial Reporting Standards (IFRS) Adoption According to The Price Crash Risk
Authors: Ahmed Wahba Amany
Published: September 2022

Demand for information on corporate social responsibility (CSR) and international financial reporting standards (IFRS) has progressively increased in tandem with the growing interest in sustainable investments. Numerous studies have established that the adoption of IFRS has often improved the information quality offered to many users through providing highly relevant, reliable and understandable information, as well as allowing companies’ accounting data to be compared to that of other companies for various periods. Crash risk is a major concern for investors and may result in higher compensation for holding higher-risk securities. This research seeks to examine the impact of corporate social responsibility on the effectiveness of adopting mandatory international financial reporting standards according to the price crash risk. To achieve this, the descriptive approach and a systematic review of previous studies, research, and literature related to the research topic and its variables were used. The results confirmed the existence of a correlation between CSR and IFRS in the financial market. Finally, the research recommended the necessity of conducting more research, analytical and empirical studies with regard to measuring the correlation among CSR and IFRS.

Enhancing the Understandability of OCL Specifications
Authors: Correa Alexandre , Werner Cláudia , Barros Márcio
Published: September 2022

OCL (Object Constraint Language) is the OMG standard language for the precise specification of constraints associated to MOF-compliant models and meta-models. Although OCL has been created with the intention to be a simpler language when compared to traditional formal specification languages, it is common to find specifications containing OCL constraints that are difficult to understand and evolve. This paper presents a set of potential problematic constructions often found in specifications written in OCL and a set of refactorings that can be applied to remove them. We also present an experimental study that has been performed to evaluate the effects of applying those strategies on the understandability of OCL specifications.
A Bio-inspired Representation Model for Engineering Self-Organizing Emergent Systems
Authors: Gatti Maíra Athanázio de Cerqueira , Lucena Carlos José Pereira de
Published: September 2022

Self-organization is a dynamic and adaptive process where components of a system acquire and maintain information about their environment and neighbors without external control. Agent-Oriented Software Engineering (AOSE) can provide methods and technologies that help building self-organizing systems. A fundamental engineering issue when designing self-organizing emergent multi-agent systems (MASs) is to achieve required macroscopic properties by manipulating the microscopic behavior of locally interacting agents. In this paper, we propose a bio-inspired approach consisting of a representation model that allows a systematic design of the desirable emergent macroscopic properties from a macro scale to the micro scale.

DoIt4Me: a tool for automating administrative tasks on Windows NT networks
Authors: Augusto Alessandro , Guimarães Célio Cardoso , Geus Paulo Lício de
Published: September 2022

The process to secure a Windows NT computer is simple when the system administrator knows the required configuration settings [13,14]. However, even with this knowledge, to apply the same configuration to hundreds of NT-based computers can be frustrating and laborious. Remote administration of a large Windows NT network is a complex task. The tools provided by standard NT installations are, at best, inadequate. The explosive growth in network sizes over the last years has resulted in large and complex sites but no significant new tools were created. This paper introduces the design and implementation of DoIt4Me, a simple and flexible tool that enables, from a single console, automation of a large number of Windows NT administrative tasks.

Analisando a Viabilidade da Implementação Prática de Sistemas Tolerantes a Intrusões
Authors: Obelheiro Rafael R. M. , Bessani Alysson Neves , Lung Lau Cheuk
Published: September 2022

A construção de sistemas seguros e invioláveis usando mecanismos tradicionais vem se tornando um objetivo cada vez mais difícil de ser atingido. O reconhecimento desse fato tem aumentado o interesse em abordagens alternativas de segurança, como a tolerância a intrusões, que aplica conceitos e técnicas de tolerância a faltas em problemas de segurança. Uma das principais questões envolvendo os sistemas tolerantes a intrusões é que muitos dos algoritmos usados pressupõem que os componentes do sistema falham ou são comprometidos de forma independente, premissa que vem sendo seguidamente questionada. Neste artigo nós mostramos que a diversidade possibilita a construção de sistemas tolerantes a intrusões reais. Nós examinamos várias formas de diversidade e discutimos como elas podem auxiliar nessa tarefa. Além disso, é mostrado um exemplo prático de como um sistema tolerante a intrusões pode ser construído usando a diversidade.
Avaliação do Emprego de Raciocínio baseado em Casos para Identificar Cenários de Intrusão em Logs de Firewalls

A análise de conteúdo de logs gerados por firewalls mostra-se fundamental para reconhecer seqüências de eventos suspeitas que indiquem estratégias utilizadas por intrusos para tentar obter acesso não autorizado a estações e serviços. Tal análise, em função do grande volume de informações armazenadas, é inviável de ser realizada de forma manual.Este artigo apresenta uma abordagem que explora a técnica de raciocínio baseado em casos, da Inteligência Artificial, para identificar, de forma automática, cenários de intrusão em logs de firewalls. O artigo descreve a avaliação da abordagem, realizada com base em logs reais gerados pelo firewall da universidade, e discute como a sintonia dos parâmetros que compõem um caso influencia na geração de alertas, procurando determinar combinações que propiciem uma relação satisfatória entre detecção de cenários de intrusão x número de alertas gerados.

The Cosmos as a Work of Art
Authors: Pruss Alexander ,   Philosophy Documentation Center
Published: September 2022

I shall defend Augustine’s holistic aesthetic response to the problem of evil by considering the variety of ways in which our vision of the cosmos is limited and how this is similar to the kinds of limitations on viewing a work of art that would make negative criticism unreasonable. At the same time, I identify an interesting asymmetry: we may be justified in making positive, but not negative, judgments about the creator’s skill on the basis of a mere partial perception.

Esta entrevista realizada com o professor Jefferson Thadeu Canfield foi coletada pela professora Janice Zarpellon Mazo, visando registrar informações para a construção de sua dissertação de mestrado, no ano de 1993. A narrativa trata do percurso acadêmico do professor Jefferson, iniciado na Escola de Educação Física da Universidade Federal do Rio Grande do Sul, onde realizou sua formação inicial, no período de 1963 a 1966. De tal modo, o depoimento ora apresentado traz, frequentemente, rememorações com relação às experiências vividas nesta instituição. Inclusive, são estabelecidas relações e/ou comparações com o Centro de Educação Física e Desportos (CEFD) da Universidade Federal de Santa Maria, onde ingressou como docente no ano de 1971, no segundo concurso público para docentes do curso de Licenciatura em Educação Física da referida universidade. Seu depoimento registra representações advindas com a fundação do CEFD, além de anotar aspectos sobre seu ingresso junto aos outros seis professores pioneiros, os quais já se encontravam em atuação na instituição e sobre os engendramentos decorridos das composições do CEFD.
Un colegio de señoritas y una escuela para párvulos pobres. La arquitectura escolar como apunte de diversidad escolar religiosa en provincias a comienzos del siglo XX
Authors: García-Lozano Rafael Ángel
Published: September 2022

En este trabajo nos acercamos a la labor educativa ejercida en la ciudad de Zamora desde comienzos del siglo XX por la Compañía de las Hijas de la Caridad de San Vicente de Paúl en dos centros gestionados por esta Sociedad de vida apostólica. Fueron abiertos precisamente 40 años después de su llegada a la capital en 1860 a instancias de la Junta Provincial de Beneficencia para atender el hospicio Nuestra Señora del Tránsito. De este modo, su tarea inicialmente asistencial tomó cuatro décadas después un cariz explícitamente docente con la dirección de sendos colegios. Gestionados por la misma institución religiosa, el colegio del Patronato de San Vicente de Paúl echó a andar en 1904 continuando la labor de la escuela situada en una barriada marginal de la ciudad y paupérrimamente sostenida por el Ayuntamiento con fondos municipales una vez cesó en su tarea la anciana maestra que la atendía. Sólo un año antes, en 1903, la Compañía abrió también el Colegio Medalla Milagrosa, movida por el impulso de los propios diputados provinciales que deseaban para sus hijas una educación a la altura de la que las religiosas daban a las niñas huérfanas internadas en el orfanato que regentaban. Nos centramos en esta investigación en el análisis de sus respectivas arquitecturas escolares como muestra de diversidad de la atención docente de la Compañía en Zamora.
La “mujer” del tardofranquismo (1960-1975): El No-Do como instrumento de control de la emancipación femenina
Authors: Guichot Reina Virginia
Published: September 2022

El Plan de Estabilización y Liberalización Económica de 1959 es considerado el hito que marca el inicio de una nueva etapa dentro del régimen franquista conocida como desarrollismo tecnocrático. Las nuevas circunstancias posibilitaban un empuje a la emancipación femenina, gracias a una mayor inclusión de las mujeres en el mundo laboral, poderosamente obstaculizada desde los inicios del nacionalcatolicismo. Dichos cambios económicos, unidos a otros culturales, cuestionaban el ideal de «ángel del hogar» que el franquismo había promovido para las mujeres. En consecuencia, el régimen dictatorial utilizó su medio de propaganda audiovisual más eficaz, el NO-DO (Noticiarios y Documentales) para salvaguardar este modelo. Nuestro objetivo es descubrir las estrategias discursivas que utilizó el NO-DO para desautorizar cualquier expectativa femenina que no sintonizase con el prototipo oficial femenino del franquismo durante el desarrollismo (1960-1975), centrando nuestra atención en reportajes que muestran noticias relacionadas con la educación, incluida la formación profesional. La metodología empleada sigue los parámetros del análisis crítico del discurso, aplicado tanto al verbal como al no verbal, precisando este último aplicar técnicas de análisis audiovisual. Como resultado, se aprecia que se desacreditan modelos femeninos alternativos al tradicional con recursos como el tono burlesco, la ironía, y, en general, el lenguaje despectivo; así como existe una escasez de imágenes de mujeres en oficios tradicionalmente masculinos. Paralelamente, se sigue reforzando, mediante palabras e representaciones visuales, el ideal nacional-católico de mujer.
Der Marsch zum Führer: los documentales y noticiarios en el adoctrinamiento de la juventud en la Alemania nazi
Authors: Almeida Aguiar Antonio
Published: September 2022

Los documentales educativos y noticiarios no han tenido una tradición como ámbito de investigación en España, salvo en los últimos años. Desde esta perspectiva, el presente artículo pretende contribuir al análisis de los documentales, así como de los mecanismos utilizados por el régimen nazi, para la promoción de determinadas propuestas educativas, tanto formales como no formales, con un claro objetivo adoctrinador en la juventud. Además de poner de relieve la instrumentalización propagandística de la cinematografía como parte fundamental de la educación en el interior del país y más allá de sus fronteras, analizamos el protagonismo de las Hitlerjugend y de la Bund Deutscher Mädel en el engranaje adoctrinador. Para fundamentar este discurso, hemos realizado un estudio a través de fuentes primarias, tanto fílmicas como textuales. Por un lado, el documental Der Marsch zum Führer, así como los noticiarios Junges Europa y NO-DO. Paralelamente, la red de instrumentos que controlaban la formación de la juventud, utilizó libros y revistas con discursos comunes a los materiales visuales trabajados, en obras como Marschtritt Deustschland y la revista Junges Europa. Los resultados ofrecen una serie de características educativas, tanto a través de símbolos visuales como de contenido escrito, que coinciden con los elementos propios de los totalitarismos europeos.

Entrevista a los secretarios generales del Sindicato de Estudiantes Juan Ignacio Ramos (1987-1991) y Bárbara Areal (1994-1998)
Authors: González-Moreno Javier
Published: September 2022

Este curso 2021-2022 se celebra el 35.º aniversario de la huelga de estudiantes del curso 1986-1987, la cual constituye el mayor conflicto estudiantil de la historia de España. Supuso el inicio de un trienio de movilizaciones contra las políticas del gobierno del PSOE, las cuales no satisfacían las expectativas de reforma de los trabajadores. Estas movilizaciones fueron in crescendo con la huelga de profesores del curso 1987-1988 y culminaron con la histórica huelga general del 14 de diciembre de 1988. La huelga estudiantil de 1986-1987 destacó por su masiva participación y por los importantes efectos que logró en la política educativa, especialmente en la extensión de la enseñanza secundaria. La organización fundamental de estas protestas fue el Sindicato de Estudiantes. Charlamos aquí sobre estos hechos y sobre la trayectoria posterior del Sindicato de Estudiantes con Juan Ignacio Ramos, su secretario general de entonces, y con Bárbara Areal, militante en aquella huelga y posteriormente secretaria general.
