In both scientific and popular circles it is often said that we are in the midst of a sixth mass extinction. Although the urgency of our present environmental crises is not in doubt, such claims of a present mass extinction are highly controversial scientifically. Our aims are, first, to get to the bottom of this scientific debate by shedding philosophical light on the many conceptual and methodological challenges involved in answering this scientific question, and, second, to offer new philosophical perspectives (...) on what the value of asking this question has been — and whether that value persists today. We show that the conceptual challenges in defining ‘mass extinction’, uncertainties in past and present diversity assessments, and data incommensurabilities undermine a straightforward answer to the question of whether we are in, or entering, a sixth mass extinction today. More broadly we argue that an excessive focus on the mass extinction framing can be misleading for present conservation efforts and may lead us to miss out on the many other valuable insights that Earth’s deep time can offer in guiding our future.

Background: The acquisition of experience is a major concern for nurses in intensive care units. Although the emotional component of the clinical practice of these nurses has been widely studied, greater examination is required to determine how this component influences their learning and practical experience. Objective: To discover the relationships between emotion, memory and learning and the impacts on nursing clinical practice. Research design: This is a qualitative phenomenological study. The data were collected from open, in-depth interviews. A total of (...) 22 intensive care unit nurses participated in this research between January 2012 and December 2014. Ethical considerations: The School of Nursing Ethics Committee approved the study, which complied with ethical principles and required informed consent. Findings: We found a clear relationship between emotion, memory and the acquisition of experience. This relationship grouped three dimensions: (1) satisfaction, to relieve the patient’s pain or discomfort, give confidence and a sense of security to the patient, enable the presence of family members into the intensive care unit and provide family members with a realistic view of the patient’s situation; (2) error experience, which nurses feel when a patient dies, when they fail to accompany a patient in his or her decision to abandon the struggle to live or when they fail to lend support to the patient’s family; and (3) the feel bad–feel good paradox, which occurs when a mistake in the patient’s care or handling of his or her family is repaired. Conclusion: Emotion is a capacity that impacts on nurses’ experience and influences improvements in clinical practice. Recalling stories of satisfaction helps to reinforce good practice, while recalling stories of errors helps to identify difficulties in the profession and recognise new forms of action. The articulation of emotional competencies may support the development of nursing ethics in the intensive care unit to protect and defend their patients and improve their relationships with families in order to maximise the potential for patient care.

Background The practice of health advocacy in nursing has been defined as a process aimed at promoting the independence and autonomy of users of health services, in addition to providing information on healthcare decision-making and offering support for decisions taken. Ethical considerations Ethics approval was not required to conduct this review. Aim This integrative review aims to synthesize evidence in the literature on health advocacy in professional nursing practice. Methods An integrative review methodology guided by Whittemore and Knalf was used. (...) Studies were identified by conducting searches on PubMed, Scopus, Web of Science, CINAHL, and LILACS databases. Of 2179 records, 34 studies matched the inclusion criteria. Results The main aspects involved in the practice of health advocacy by professional nurses are related to the ethical principles of the nursing profession, such as protecting patients seeking autonomy and care. Furthermore, the practice of health advocacy by nurses requires an empathetic attitude, responsibility, and assertive communication. Conclusion The diverse possibilities for the practice of advocacy synthesized in this study allow nurses to approach and become familiarized with the topic, being able to acquire and complement knowledge that will reflect on their professional practice in different work environments such as the educational field, in hospital practice, or basic health care.

This paper sets forth the findings of a research study undertaken in Chihuahua, Mexico. The length of stay of 1 866 employees in six maquiladora plants is analyzed across a maximum of 24 months. By drawing on discrete time hazard modeling, the research analyzes the extent to which work and nonwork factors contributed to employee length of stay in the late 1980s. It examines, in particular, the influence of position, cohort grouping, plant type, and demographic characteristics on employee duration in (...) the participating plants.The findings show that line operators at the peak of high employment turnover in the maquiladora industry remained employed for an average of 10 months. The study highlights important differences, for the results were not uniform across all maquiladora employees. There were variations in length of stay among employees of different types of plants, in different positions in the same company, different months of entry, and different migrant status. (shrink)

este artigo tem como propósito examinar os argumentos de Kant quanto à possibilidade do restabelecimento do bem face ao mal radical na natureza humana. A investigação aqui proposta toma como ponto de partida e foco central a afirmação kantiana de que intenção ou máxima suprema está corrompida pelo mal, e busca, a partir das consequências de tal constatação e dos argumentos fornecidos por Kant, delinear as possibilidades e o caráter do restabelecimento do bem no interior de tal intenção.

Deconstructing the Feminine looks beyond impasses of binary thought and essentialist conceptions of women and the feminine from a contemporary perspective. With a multicentred and complex approach, and an ongoing dialogue with Freud, Leticia Glocer Fiorini addresses questions relating to love, sexual desire, maternity, beauty, and the passing of time by reconsidering the gender binary and underlying power relations. Glocer Fiorini's work highlights current debates concerning women, the feminine, and sexual difference, as well as discussing topics which have caused (...) controversy throughout the history of the psychoanalytic movement. The updated and expanded edition distinguishes between the concept of sexual difference and the category of 'difference' as it applies at various heterogenous levels and includes new approaches reflecting on the 'feminine enigma', hysteria, feminine masochism, and masculinity. Deconstructing the Feminine will be of great interest to psychoanalysts in clinical practice and in training, as well as to scholars of gender, sexuality, and women's studies. (shrink)

As considerações do presente artigo referem-se a demandas de paradigmas atuais associados com a pós-modernidade. Salientam-se as possíveis relações entre a fragilização do Estado de Bem Estar Social e a emergência de entidades que ocupam, cada vez mais, espaços de formação com substancial apoio da sociedade civil, apontando o Fórum de Educação para o Trabalho - FORTE, como um exemplo dessa prática, em Porto Alegre, desde 1994.

The empirical study of language is a young field in contemporary linguistics. This being the case, and following a natural development process, the field is currently at a stage where different research methods and experimental approaches are being put into question in terms of their validity. Without pretending to provide an answer with respect to the best way to conduct linguistics related experimental research, in this article we aim at examining the process that researchers follow in the design and implementation (...) of experimental linguistics research with a goal to validate specific theoretical linguistic analyses. First, we discuss the general challenges that experimental work faces in finding a compromise between addressing theoretically relevant questions and being able to implement these questions in a specific controlled experimental paradigm. We discuss the Granularity Mismatch Problem (Poeppel and Embick, 2005 ) which addresses the challenges that research that is trying to bridge the representations and computations of language and their psycholinguistic/neurolinguistic evidence faces, and the basic assumptions that interdisciplinary research needs to consider due to the different conceptual granularity of the objects under study. To illustrate the practical implications of the points addressed, we compare two approaches to perform linguistic experimental research by reviewing a number of our own studies strongly grounded on theoretically informed questions. First, we show how linguistic phenomena similar at a conceptual level can be tested within the same language using measurement of event-related potentials (ERP) by discussing results from two ERP experiments on the processing of long-distance backward dependencies that involve coreference and negative polarity items respectively in Dutch. Second, we examine how the same linguistic phenomenon can be tested in different languages using reading time measures by discussing the outcome of four self-paced reading experiments on the processing of in-situ wh -questions in Mandarin Chinese and French. Finally, we review the implications that our findings have for the specific theoretical linguistics questions that we originally aimed to address. We conclude with an overview of the general insights that can be gained from the role of structural hierarchy and grammatical constraints in processing and the existing limitations on the generalization of results.

Resumen. A la Sociedad Cooperativa, se le distingue por ser una sociedad mercantil con ciertas particularidades a diferencia de los demás tipos de sociedades, tan es así que se rige por su legislación especial. En los últimos años en México, se ha detectado un incremento de sociedades cooperativas dedicadas al suministro de personal, toda vez que el esquema fue considerado por algunos especialistas fiscales como una alternativa para las empresas que buscan disminuir sus cargas impositivas derivadas de las relaciones laborales. (...) Dicho esquema básicamente consiste en transferir a los trabajadores de las empresas a la sociedad cooperativa, los cuales al ser registrados como socios, las remuneraciones que estos perciben son bajo el concepto de previsión social; en lugar de salarios evitando así la retención y pago del Impuesto Sobre la Renta correspondiente. Con motivo de lo anterior, en la presente investigación se analizan y califican los aspectos más relevantes del asunto.Palabras claves. Sociedad cooperativa, evasión fiscal, outsourcing, previsión social.. A cooperative society is distinguished as a corporation with certain features unlike other types of companies, so much so that is governed by a special legislation. In recent years Mexico has seen an increase of cooperative societies dedicated to supply services, since the scheme was considered by some experts as an alternative tax for companies seeking to lower their tax burdens resulting from relations. This scheme basically consists of transferring workers from companies to the cooperative, which when registered as members the remuneration that they perceive are under the concept of social welfare, instead of avoiding wage withholding and payment of VAT Income for. On the occasion of the above, this research analyzes and scored the most relevant aspects of the case. (shrink)

Este artigo pretende apresentar uma análise comparativa entre as obras de fundamentação da moralidade e o escrito sobre a religião no que tange à estrutura da ação por dever. Tal análise se justifica em vista de Kant, no escrito sobre a religião, apresentar a definição da ação por dever e da ação moralmente má nos termos de hierarquia e ordem moral dos móbiles, formulação que, aparentemente, não é apresentada no âmbito da fundamentação da moral. Dessa análise se sobressai, ainda, a (...) necessidade de, ao menos amplamente, fornecer dados quanto à função e o aparecimento da noção de ordem moral dos móbiles no interior do discurso moral kantiano.

The attack on the US Capitol on 6 January 2021 was a tragic illustration of the existential threat that the viral spread of disinformation poses in the age of social media and twenty-four-hour news. From climate change denialism to the frenzied conspiracy theories and racist mythologies that fuel antidemocratic white nationalist movements in the United States and abroad, What Would Cervantes Do? is a lucid meditation on the key role the humanities must play in dissecting and combatting all forms of (...) disinformation. David Castillo and William Egginton travel back to the early modern period, the first age of inflationary media, in search of historically tested strategies to overcome disinformation and shed light on our post-truth market. Through a series of critical conversations between cultural icons of the twenty-first century and those of the Spanish Golden Age, What Would Cervantes Do? provides a tour-de-force commentary on current politics and popular culture. Offering a diverse range of Cervantist comparative readings of contemporary cultural texts – movies, television shows, and infotainment – alongside ideas and issues from literary and cultural texts of early modern Spain, Castillo and Egginton present a new way of unpacking the logic of contemporary media. What Would Cervantes Do? is an urgent and timely self-help manual for literary scholars and humanists of all stripes, and a powerful toolkit for reality literacy. (shrink)

The aim of this paper is to show that any process of benefit sharing that does not guarantee the representation and participation of women in the decision-making process, as well as in the distribution of benefits, contravenes a central demand of social justice. It is argued that women, particularly in developing countries, can be excluded from benefits derived from genetic research because of existing social structures that promote and maintain discrimination. The paper describes how the structural problem of gender-based inequity (...) can impact on benefit sharing processes. At the same time, examples are given of poor women’s ability to organise themselves and to achieve social benefits for entire communities. Relevant international guidelines (e.g. the Convention on Biodiversity) recognise the importance of women’s contributions to the protection of biodiversity and thereby, implicitly, their right to a share of the benefits, but no mechanism is outlined on how to bring this about. The authors make a clear recommendation to ensure women’s participation in benefit sharing negotiations by demanding seats at the negotiation table. (shrink)

Contexto: Algumas experiências religiosas e/ou espirituais apresentam um caráter dissociativo. Há carência de estudos que indiquem critérios diferenciais entre a dissociação patológica e saudável em contexto religioso. Objetivo: Este estudo pretende observar as experiências dissociativas sob diferentes perspectivas: uma ligada à psicopatologia e a outra, à saúde. Método: Ensaio temático com a literatura disponível sobre o assunto. Bases de dados: Pubmed e PsychINFO. Também foi feita busca manual de artigos relacionados ao assunto. Resultados: 1. Historicamente, alguns autores se debruçaram sobre (...) as relações entre dissociação e fenômenos religiosos, mas os dados não são conclusivos; 2. A dissociação acontece em um continuum entre saúde e doença; 3. A psiquiatria transcultural oferece aporte para a compreensão de experiências dissociativas, como o transe de possessão, contextualizando-as culturalmente; 4. Há uma série de estudos feitos no Brasil, que exploram o diagnóstico diferencial entre experiências religiosas saudáveis e patológicas. Conclusões: Experiências religiosas/espirituais de caráter dissociativo, podem ser consideradas saudáveis se apresentarem ausência de sofrimento, controle, forem contextualizadas e trouxerem benefício para o indivíduo. Indivíduos sem Autodirecionamento e com experiências autocentradas mostram maior probabilidade de desenvolver patologia. Futuros estudos deverão explorar empírica e longitunalmente estas questões.

"The caring progression of cultures can also be seen when we look back at cultures of two thousand years ago or even of two hundred years ago. Today, it can be seen, globally, in attempts to replace capitalism's caring for a chosen few with socialism's intent of expanding caring for more of life and its environment. Thus, Becoming Human is a movement in making known our species' evolution toward humanness." --Amazon.com.

A vivência das crianças ciganas no mundo apresenta várias lacunas que vêm sendo estudadas por pesquisadores da área da sociologia, antropologia, psicologia e educação, com a intenção de compreender a forma como as escolas enfrentam o desafio de ensinar, com êxito, crianças de etnias diferentes. Discutir acerca da vida da criança cigana e o brincar no seu processo de escolarização frente aos olhos dos professores se constitui no nosso principal objetivo. A ênfase maior deste estudo está centrada na percepção dos (...) professores sobre a inserção das crianças ciganas no processo de escolarização na rede regular de ensino, assim como conhecer de que forma o lúdico está inserido no ambiente educacional e se vem contribuindo para diminuir o insucesso escolar de alunos/as de etnia cigana.

Toma-se como objetivo tecer considerações acerca do conceito de autorreflexão e emancipação, entrelaçando-o à pesquisa-ação, por meio do diálogo entre Jürgen Habermas, Theodor W. Adorno, Wilfred Carr e Stephen Kemmis. Os conceitos de autorreflexão e emancipação surgem na Escola de Frankfurt através de Adorno e são incorporados por Habermas, que dá outro sentido a eles. Carr e Kemmis, ao refletirem sobre a pesquisa-ação emancipatória na educação, tomam Habermas como alicerce e constituem o conceito de autorreflexão crítica. A partir das considerações (...) dos autores, o artigo reflete acerca da autorreflexão incorporada na metodologia da pesquisa-ação, principalmente no tocante à formação continuada de profissionais da educação. À luz dos pressupostos habermasianos, defendem-se os conceitos de autorreflexão e emancipação pela via da ação comunicativa, na qual o paradigma da consciência é transposto para o paradigma da linguagem. Compreende-se que para Adorno a autorreflexão está atrelada diretamente à liberdade, ao pensamento crítico e à autonomia, que guiam o indivíduo para a emancipação. Enquanto para Habermas, a autorreflexão vincula-se à linguagem e à comunicação, entre dois ou mais sujeitos, que os guiam para a emancipação. Carr e Kemmis inspirados na espiral cíclica proposta por Lewin e na autorreflexão de Habermas, vão defender a espiral autorreflexiva na pesquisa-ação. Diante disso, entende-se que os problemas da educação têm na racionalidade comunicativa perspectivas de mudanças sólidas, especialmente pela via de processos formativos. (shrink)

The purpose of this paper aims to unravel the ideological strategy that rises from the well-celebrated epistemic rigor of neoclassical economic thought. From the Economics Nobel Price Paul Krugman’s popularized connotation naming to "freshwater" economists as those fervent followers of the most orthodox academic creed, we will expose the logical inconsistency and empirical implausibility of such thought’s underlying assumptions: perfect competence and equilibrium’s approaching. From a critical analysis that will be conducted from each of those mentioned assumptions, we will argued (...) that the neoclassical thought is an ideological strategy subverting reality’s principles, overcoming "artificially" those relevant deficiencies and limitations of its theoretical approach. A lo largo de este trabajo se intenta desvelar la estrategia ideológica que emana del celebrado rigorismo epistémico del pensamiento neoclásico de economía. Desde la connotación popularizada por el Nobel Paul Krugman a los economistas de "agua dulce" como aquellos fervientes seguidores del credo académico más ortodoxo, expondremos la incoherencia lógica e imposibilidad empírica de los supuestos fundamentales de su pensamiento: competencia perfecta y aproximación al equilibrio. Desde un examen crítico que irá conduciéndose por cada uno de tales supuestos, resolveremos cómo el marco neoclásico no es más que una estrategia ideológica que subvirtiendo los principios de lo real consigue superar solo "artificialmente" las importantes deficiencias y limitaciones de su marco teórico.

Addressing the study of human action from Mises’s perspective of the praxeological method is in itself highly controversial. Particularly, if it attempts to identify the ultimate basis of human development, it will face unmanageable problems in analytical and normative terms. The incapability to withdraw from the socalled self-evident judgments comes together with the refusal of the elements that address its operability. Dependent of a soft well-being concept, it is unable to establish interpersonal comparisons, and this in turn frustrates any kind (...) of attempt to design a convincing social justice theory. A Hegelian perspective brings order to and improves both the moral and the operability dimension of the praxeological interpretation of economics. (shrink)

En la teoría etnológica y política contemporánea, la conceptualización de las acciones de adscriptos étnicos en términos de acciones orientadas por intereses constituye el núcleo conceptual de la definición de lo político. Comunalizaciones, movimientos culturales, democracia plural radical, reivindicaciones de derechos colectivos diferenciados, son todas ellas nociones que refieren a acciones colectivas y a la producción de identidades sobre la base de orientaciones culturales o ethos comunes en el ámbito de la esfera pública. La interpretación de tales expresiones como formas (...) institucionalizadas y públicas de acción colectiva se funda en un concepto de vida política como "vida común", como "acción colectiva pública". La siguiente presentación se propone interrogar los márgenes categoriales sobre los que se construye y fundamenta la teoría etnopolítica contemporánea, analizando las nociones de "común" que ponen en circulación como así también la tensión entre universalismo y particularismo que hacen emerger. In the contemporary political and ethnological theory, the conceptualization of the ethnic ascribed people actions in terms of "interest actions" is the conceptual core of the definition of politics. Communalizations, cultural movements, radical pluralist democracy, differentiated collective rights claims, are all notions that refer to collective action and the production of identities based on cultural orientations or common ethos in the field of public sphere. The interpretation of such expressions, as institutionalized and public forms of collective action, is based on a concept of political life as "common life", as "public collective action". The following article proposes to inquire the categorical margins on which the contemporary ethno-political theory is built and founded, analyzing not only the notions of "common" put into circulation but also the tension between universalism and particularism that do emerge themselves.

Pensadores griegos y orientales, filósofos antiguos, medioevales y modernos, han tocado el tema de lo corporal de manera fragmentaria que reducen lo corpóreo a mero instrumento. Para evitar este tipo de interpretaciones, queda el expediente de acudir a la síntesis holística; a la versión del "cuerpo total" que somos. La economía imperante es la del "cuerpo poseído". Se tasa, vende y desecha en el mercado la fuerza de trabajo. Se ejerce sobre él una violencia que nos rebasa en todos los (...) frentes; es radical, porque atenta contra la integridad y la dignidad de los cuerpos. Restañar las heridas corporales de nuestros pueblos requiere de la formulación y siembra del conocimiento de la Ética del cuerpo que deberá ir acompañada por un proceso de reconstrucción simbólica de la idea de "cuerpo" en el que todos participemos. Si armonizan necesidades y capacidades corporales propias y ajenas y compaginan nuestras acciones con el respeto al entorno natural, casa del cuerpo, podremos vislumbrar que vamos sobre el camino correcto. The Greek and Eastern thinkers, ancient, medieval and modern philosophers, have dealt with the body only in a fragmentary way that sees it as a mere instrument. To avoid this kind of interpretation we resort to a holistic synthesis-the "total body" version that we really are. The dominant economics is the one of the "possessed body" that can be priced, sold and disposed of as working force. An overpowering violence is applied to it; it is a radical violence as it attempts on bodies' integrity and dignity. The healing of the wounded bodies of our people requires formulating and planting the seeds of the body's ethics that will accompany the reconstruction of an idea of body to be shared by all of us. If we harmonize our own and others' body's needs and abilities, and our actions are in accordance with our natural surroundings, we will be able to make out the right path. (shrink)

Este artículo aborda desde una perspectiva crítica la relación entre las categorías de democracia y ciudadanía en la ciudad de Valparaíso durante la última década de postdictadura.
