In this article, the relationship between ethics in general and business ethics in particular to Stoic philosophy is investigated. Stoic ethics is used as a research tool, which step-by-step deciphers the position of the human as a functional part of a larger organization, such as the natural environment or civil society. Ethics is inextricably linked to the rational, free choice of what is right for both the individual and the total organism. Ethical rightness imposes a form of rational order within the organization, in the sense that each part must perform the function appropriate to its abilities. At the maximum degree of ethical integration stands the paradigm of the Stoic sage as a model of a virtuous leader, who is able to understand the causes of each decision or action and direct the organization towards the set goal. From this perspective, concepts such as leadership, organizational ethics, or corporate social responsibility acquire an objective status and view the philosophical cosmopolitanism of the Stoic sage as a timeless example of ethical rightness.

The following is part of an ongoing dialogue that Donaldo Macedo and Paulo Freire have been having since 1983. As it attempts to address the current criticisms of Freire's work along the lines of gender and race, this dialogue not only challenges the frequent misinterpretations of his leading philosophical ideas by conservative and some liberal educators, but will also embrace contemporary educational issues and discuss what it means to educate for critical citizenry in the ever-increasing multiracial and multicultural world of the twenty-first century.

Shor and Freire discuss here the dialogical method of liberatory education. Dialogue is not a mere technique to achieve some cognitive results; dialogue is a means to transform social relations in the classroom, and to raise awareness about relations in society at large. Dialogue is a way to recreate knowledge as well as the way we learn. It is a mutual learning process where the teacher poses critical problems for inquiry. Dialogue rejects narrative lecturing where teacher talk silences and alienates students. In a problem-posing participatory format, the teacher and students transform learning into a collaborative process to illuminate and act on reality. This process is situated in the thought, language, aspirations, and conditions of the students. It is also shaped by the subject matter and training of the teacher, who is simultaneously a classroom researcher, a politician, and an artist.

A new process concept, "quenching and partitioning" (Q&P) has been proposed recently for creating steel microstructures with retained austenite. The process involves quenching austenite below the martensite-start temperature, followed by a partitioning treatment to enrich the remaining austenite with carbon, thereby stabilizing it to room temperature. The process concept is reviewed here, along with the thermodynamic basis for the partitioning treatment, and a model for designing some of the relevant processing temperatures. These concepts are applied to silicon-containing steels that are currently being examined for low-carbon TRIP sheet steel applications, and medium-carbon bar steel applications, along with a silicon-containing ductile cast iron. Highlights of recent experimental studies on these materials are also presented, that indicate unique and attractive microstructure/property combinations may be obtained via Q&P. This work is being carried out through a collaborative arrangement sponsored by the NSF in the USA, CNPq in Brazil, and the EPSRC in the United Kingdom.

PURPOSE: To identify the structure of the iliotibial tract at knee level, as well as its insertions, layer arrangement, and relationship with other structures of the lateral region of the knee and to compare the findings with available literature. METHODS: Ten detailed anatomic dissections were performed by using incisions as recommended by the literature in fresh cadaver knees identifying the iliotibial tract components. RESULTS: The authors observed an iliotibial tract arrangement in superficial, deep, and capsular-osseous layers. Insertions have been described as follows: at linea aspera, at the upper border of the lateral epicondyle, at the patella, and at Gerdy's tibial tuberculum and across the capsular-osseous layer. CONCLUSIONS: The iliotibial tract (ITT) has important interconnections to the femur, the patella, and the lateral tibia; the iliopatellar band joins the ITT to the patella through the superficial oblique retinaculum and the lateral femoropatellar ligament, and the ITT capsular-osseous layer presents differentiated fibers in an arched arrangement that borders the femoral condyle and inserts laterally to the Gerdy's tubercle. CLINICAL RELEVANCE: The iliotibial tract can be considered as an anterolateral knee stabilizer, particularly its capsular-osseous layer, which, together with the anterior cruciate ligament, constitutes a functional unit forming a spatial "horseshoe" form. The detailed description of the structures forming iliotibial tract plays an important role in the study of knee instabilities. Its important tibial, femoral, and patellar connections are described so that better understanding of tibial femoral instability on the lateral side as well as patellofemoral instability can be achieved and mechanisms of repair can be conceived.

Resenha do livro A Imagem do Corpo: as energias construtivas da psique. Paul Schilder (1950). Tradução de Rosanne Wertman. São Paulo: Martins Fontes, 1994.

The question of the importance of reading is addressed by considering the ways in which experience itself is read through the interaction of the self and the world. Through examining memories of childhood, it is possible to view objects and experiences as texts, words, and letters and to see the growing awareness of the world as a kind of reading through which the self learns and changes. The actual act of reading literary texts is seen as part of a wider process of human development and growth based on understanding both one's own experience and the social world. Learning to read must be seen as one aspect of the act of knowing and as a creative act. Reading the world thus precedes reading the word and writing a new text must be seen as one means of transforming the world.

Purpose – The purpose of this paper is to present a literature review of humanitarian logistics (HL) that aims to identify trends and suggest some directions for future research. Design/methodology/approach – This conceptual paper develops a research framework for literature review through qualitative and quantitative content analysis. First, previous literature reviews in HL are updated and detailed. Then, seven classification criteria are added to earlier ones in order to advance the literature analysis. Findings – The conclusions identify some literature gaps and research opportunities. The main conclusions are the need for more studies into the disaster recovery phase and the need for closer relationships between academia and humanitarian organizations to increase the number of applied research. Research limitations/implications – The literature is limited to academic peer-reviewed journals because of their academic relevance, accessibility, and ease of searching. Practical implications – Help potential researchers to set up a research agenda for future work. Social implications – Reinforce earlier calls to increase truly applied research and improve social impact of the field. Originality/value – In total, 228 papers that were published in the HL area are reviewed, giving rise to the most extensive literature review in this area. New dimensions for literature review in HL are proposed, which give some new insights into potential research directions.

Este artigo centra-se no tema assistência a idosos dependentes por doença crônica e degenerativa, e chama a atenção para o papel do cuidador em casa. A recomendação para que os cuidados aos idosos dependentes sejam desenvolvidos no domicílio está ganhando mais força, muitas vezes de maneira incauta por parte dos profissionais de saúde. Delegar à família a função de cuidar necessita de clareza sobre a estrutura familiar, o tipo de cuidado a ser executado, o tempo necessário, as características da doença e o acompanhamento profissional. Em países onde o envelhecimento populacional se deu mais lentamente do que no Brasil, os cuidados e os cuidadores familiares são objeto de políticas e programas de Saúde Pública.

Permanent hearing loss is a leading global health care burden, with 1 in 10 people affected to a mild or greater degree. A shortage of trained healthcare professionals and associated infrastructure and resource limitations mean that hearing health services are unavailable to the majority of the world population. Utilizing information and communication technology in hearing health care, or tele-audiology, combined with automation offer unique opportunities for improved clinical care, widespread access to services, and more cost-effective and sustainable hearing health care. Tele-audiology demonstrates significant potential in areas such as education and training of hearing health care professionals, paraprofessionals, parents, and adults with hearing disorders; screening for auditory disorders; diagnosis of hearing loss; and intervention services. Global connectivity is rapidly growing with increasingly widespread distribution into underserved communities where audiological services may be facilitated through telehealth models. Although many questions related to aspects such as quality control, licensure, jurisdictional responsibility, certification and reimbursement still need to be addressed; no alternative strategy can currently offer the same potential reach for impacting the global burden of hearing loss in the near and foreseeable future.SumarioLa pérdida auditiva permanente es una importante carga para los cuidados de la salud a nivel mundial, con 1 de cada 10 personas afectadas en grado ligero o mayor. La escasez de profesionales entrenados en cuidados de la salud y de infraestructura asociada y la limitación de recursos determina que los servicios de salud auditiva no estén disponibles para la mayoría de la población mundial. La utilización de información y tecnología de la comunicación para los cuidados de la salud auditiva o teleaudiología, combinada con la automatización, ofrece oportunidades únicas para mejorar los cuidados clínicos, ampliar el acceso a los servicios y tener cuidados de salud auditiva costoefectivos y sustentables. La Teleaudiología ha demostrado un potencial significativo en áreas como las de educación y adiestramientio de profesionales de la salud auditiva, profesionales afines, padres y adultos con problemas auditivos; tamiz de problemas auditivos; diagnóstico de pérdidas auditivas y servicios de intervención. La conectividad global está creciendo rápidamente y ha aumentado de manera generalizada su distribución en comunidades con pocos servicios, en donde los servicios audiológicos pueden facilitarse a través de modelos de telesalud. No obstante, existen muchas dudas que deben resolverse y que están relacionadas con aspectos como control de calidad, regulación del ejercicio profesional, responsabilidad jurisdiccional, certificación y reembolso de servicios, pero no existe como alternativa ninguna otra estrategia que pueda ofrecer actualmente el mismo potencial, para impactar el peso global de las pérdidas auditivas en el futuro cercano o previsible.

OBJECTIVE: Meditation techniques are widely used as therapy and wellbeing practices, but there are growing concerns about its potential for harm. The aim of the present study is to systematically review meditation adverse events (MAEs), investigating its major clinical categories and its prevalence. METHOD: We searched PubMed, PsycINFO, Scopus, Embase and AMED up to October 2019. Eligible studies included original reports of meditation practices (excluding related physical practices such as Yoga postures) with adult samples across experimental, observational and case studies. We identified a total of 6742 citations, 83 of which met the inclusion criteria for MAEs with a total of 6703 participants who undertook meditation practice. RESULTS: Of the 83 studies analysed, 55 (65%) included reports of at least one type of MAE. The total prevalence of adverse events was 8.3% (95% CI 0.05-0.12), though this varied considerably across types of studies - 3.7% (95% CI 0.02-0.05) for experimental and 33.2% (95% CI 0.25-0.41) for observational studies. The most common AEs were anxiety (33%, 18), depression (27%, 15) and cognitive anomalies (25%, 14); gastrointestinal problems and suicidal behaviours (both 11%, 6) were the least frequent. CONCLUSION: We found that the occurrence of AEs during or after meditation practices is not uncommon, and may occur in individuals with no previous history of mental health problems. These results are relevant both for practitioners and clinicians, and contribute to a balanced perspective of meditation as a practice that may lead to both positive and negative outcomes.

Embora o cenário internacional forneça um sem-número de contribuições feministas para a compreensão, o combate e a prevenção da violência de gênero, tomar-se-á, neste artigo, apenas o Brasil para uma breve análise. Ao longo da análise do tema expresso no título estabelecer-se-ão distinções úteis entre diferentes modalidades deste tipo de violência. Por ora, basta esclarecer o conceito mais abrangente, mencionando-se as categorias sociais, alvo das agressões – físicas, sexuais, emocionais – dos machos ou de quem lhes faz as vezes.

OBJECTIVE: Adverse life events, especially early trauma, play a major role in the course and expression of bipolar disorder (BD). The aim of this article is to present a systematic review about the impact of childhood trauma on the clinical course of BD. METHOD: A computer-aided search was performed in Medline, ISI database, EMBASE, PsychInfo, Centre for Reviews and Dissemination, and Databases of Thomson Reuters at April 2011, supplemented by works identified from the reference lists of the first selected papers. Two investigators systematically and independently examined all articles, selecting those according inclusion and exclusion criteria. RESULTS: Four hundred fifteen articles were identified, of which 19 remained in the review after exclusion criteria were applied. In general, childhood maltreatment predicted worsening clinical course of BD. After assessing the quality of the data and of the measurements, childhood maltreatment can be strongly associated to early onset of disorder, suicidality, and substance abuse disorder in patients with BD. CONCLUSION: Data suggest that childhood abuse and neglect are risk factors associated with worsening clinical course of BD. The conclusions should be interpreted with caution because all the studies included are cross-sectional and the majority are showing inconsistencies regarding childhood trauma as independent variable and how it is assessed.

Microsatellites or SSRs (simple sequence repeats) are ubiquitous short tandem duplications occurring in eukaryotic organisms. These sequences are among the best marker technologies applied in plant genetics and breeding. The abundant genomic, BAC, and EST sequences available in databases allow the survey regarding presence and location of SSR loci. Additional information concerning primer sequences is also the target of plant geneticists and breeders. In this paper, we describe a utility that integrates SSR searches, frequency of occurrence of motifs and arrangements, primer design, and PCR simulation against other databases. This simulation allows the performance of global alignments and identity and homology searches between different amplified sequences, that is, amplicons. In order to validate the tool functions, SSR discovery searches were performed in a database containing 28 469 nonredundant rice cDNA sequences.

The main objectives of this theoretical paper are to compare some constructivist-related learning theories and explore how they can be adequately used in educational technology and distance education. After a brief introduction, constructivism is defined as a general philosophy of education encompassing several different learning theories. The article then presents and discusses the following theories: situated cognition, activity theory, experiential learning, anchored instruction, and authentic learning. Connectivism or distributed learning is also presented as a new and important theory, including its pedagogical view and practice in massive open online courses (MOOCs). These theories are then organized in a coherent way, classified under the constructivist umbrella, pointing their common and distinctive features. Connectivism is positioned as a new philosophy of education for the digital age, making Vygotsky’s concept of zone of proximal development (ZPD) more flexible and stretching it to include learning that lies outside the learner, in social networks and technological tools. The text finally proposes further work on how these theories can be properly combined and used as frameworks for constructivist projects and activities in the fields of educational technology and distance education. The article is based on the search and review of peer-reviewed articles on constructivism, connectivism, the other aforementioned theories, and education technology and distance education._________________________________________________________Este artículo teórico pretende comparar algunas teorías de aprendizaje relacionadas con el constructivismo y explorar cómo pueden usarse adecuadamente en el campo de la tecnología educativa y la educación a distancia. Después de una breve introducción, el constructivismo queda definido como una filosofía general de la educación que abarca varias teorías de aprendizaje diferentes. El artículo presenta y analiza las siguientes teorías: cognición situada, teoría de la actividad, aprendizaje experiencial, instrucción anclada y aprendizaje auténtico. El conectivismo o aprendizaje distribuido también se presenta como una nueva e importante teoría, que incluye su visión pedagógica y práctica en cursos masivos y abiertos en línea (MOOCs). Organizamos estas teorías de manera coherente bajo el paraguas constructivista e indicamos las principales similitudes y diferencias entre ellas. El conectivismo se posiciona como una nueva filosofía de la educación para la era digital, flexibilizando y ampliando el concepto de Zona de Desarrollo Próximo (ZDP) de Vygotsky para incluir el aprendizaje que se encuentra fuera del alumno, en redes sociales y herramientas tecnológicas. El texto finalmente propone un trabajo adicional sobre cómo estas teorías pueden combinarse y utilizarse adecuadamente como marcos para proyectos y actividades constructivistas en los campos de la tecnología educativa y la educación a distancia. El artículo se basa en la investigación y revisión de artículos revisados por pares sobre el constructivismo, el conectivismo, las otras teorías mencionadas y la tecnología educativa y la educación a distancia.

Potential effects of shift work on health are probably related to the misalignment between the light-dark cycle and the human activity-rest cycle. Light exposure at night mediates these effects, including social misalignment and leads to an inversion of activity and rest, which, in turn, is linked to changes in behaviours. This article reviews the epidemiological evidence on the association between shift work and health, and possible mechanisms underlying this association. First, evidence from findings of the meta-analyses and systematic reviews published in the last 10 yr is presented. In addition, it reports the larger single-occupation studies and recent large population-based studies of the general workforce. Koch's postulates were used to evaluate the evidence related to the development of disease as a result of exposure to shift work. Finally, we discussed limitations of the multiple pathways that link shift work with specific disorders and the methodological challenges facing shift work research. We concluded that the clearest indications of shift work being the cause of a disease are given when there is a substantial body of evidence from high quality field studies showing an association and there is good evidence from laboratory studies supporting a causal explanation of the link.
