Attempt of trans-disciplinary analysis of the evolutionary value of bioethics is realized. Currently, there are High Tech schemes for management and control of genetic, socio-cultural and mental evolution of Homo sapiens (NBIC, High Hume, etc.). The biological, socio-cultural and technological factors are included in the fabric of modern theories and technologies of social and political control and manipulation. However, the basic philosophical and ideological systems of modern civilization formed mainly in the 17–18 centuries and are experiencing ever-increasing and destabilizing risk-taking (...) pressure from the scientific theories and technological realities. The sequence of diagnostic signs of a new era once again split into technological and natural sciences’ from one hand, and humanitarian and anthropological sciences’, from other. The natural sciences series corresponds to a system of technological risks be solved using algorithms established safety procedures. The socio-humanitarian series presented anthropological risk. Global bioethics phenomenon is regarded as systemic socio-cultural adaptation for technology-driven human evolution. The conceptual model for meta-structure of stable evolutionary strategy of Homo sapiens (SESH) is proposes. In accordance to model, SESH composed of genetic, socio-cultural and techno-rationalist modules, and global bioethics as a tool to minimize existential evolutionary risk. An existence of objectively descriptive and value-teleological evolutionary trajectory parameters of humanity in the modern technological and civilizational context (1), and the genesis of global bioethics as a system social adaptation to ensure self-identity (2) are postulated. -/- .

Learner autonomy has gained particular attention in Vietnamese higher education since a major education reform launched in 2005. Although a number of studies have been conducted to investigate the concept in the Vietnamese higher education context, most of them have focused on exploring teachers’ and students’ perceptions and beliefs around the concept of autonomy (T. V. Nguyen, 2011; Dang, 2012; Humphreys & Wyatt, 2013; T. N. Nguyen, 2014), and on the possibility of promoting it in Vietnamese universities (Trinh, 2005; L. (...) T. C. Nguyen, 2009; Q. X. Le, 2013; Phan, 2015). There appear to be no studies on the demonstration of learner autonomy and the potential factors, including factors relating to assessment practice, that support or inhibit its demonstration in the Vietnamese higher education context. Building on a social constructivist paradigm and sociocultural theories of learning, this qualitative case study aims to investigate the demonstration of learner autonomy in the context of assessment in English as a foreign language (EFL) classes in a university in Vietnam, and the (potential) factors in assessment that facilitate or constrain the demonstration of learner autonomy in that context. The data were collected through participant observation of teachers’ and students’ practices in three EFL classes at the university during a complete semester, one-on-one semi-structured interviews with three teachers and sixteen students, and post-observation interviews with the three teachers and their students. Additional data which characterised the context of the study were gathered and included documents at the researched university relating to higher education policies, assessment policies, English teaching and learning policies, EFL curriculum and syllabus, test samples, and English teaching textbooks. The study found that students generally demonstrated a low level of autonomy in the classroom despite their positive attitude towards the concept and their awareness of its role in English learning. Primary contributing factors included negative washback of current assessment systems on teaching and learning practices, prescribed assessment practices in the class, teachers’ and learners’ limited and divergent understanding about the concept of learner autonomy, and their limited understanding about the role of assessment in learning in general and in learner autonomy promotion and development in particular. The study also found that students who stated that English was relevant to their personal needs were generally more autonomous outside of the classroom than inside it. Findings from this study support the view that learner autonomy reflects the relationship between learners and the learning environment, and is an emergent product of the interaction between learners and contextual factors including their teacher, their peers, the learning task, class rules and values, and university values and regulations. The study’s findings are significant, as they highlight the social dimension of learner autonomy and the importance of facilitating favourable conditions for teachers to provide learner autonomy and for learners to manifest it. The study also highlights the need to reconsider assessment practices to promote learner autonomy. (shrink)

Stable adaptive strategy of Homo sapiens (SASH) is a result of the integration in the three-module fractal adaptations based on three independent processes of generation, replication, and the implementation of adaptations — genetic, socio-cultural and symbolic ones. The evolutionary landscape SASH is a topos of several evolutionary multi-dimensional vectors: 1) extraversional projective-activity behavioral intention (adaptive inversion 1), 2) mimesis (socio-cultural inheritance), 3) social (Machiavellian) intelligence, 4) the extension of inter-individual communication beyond their own social groups and their own species in (...) the rest of the world, 5) the symbolic system of communication (symbolic inheritance), 6) spiritualistic trans- formation of emotionally-shaped components of mentality, 7) the dominance of the rationalist thought mentality (enhancer of adaptive inverse 1), 8) a recursive distribution of projective-activity intentions on the man himself his genome, psyche and culture (Adaptive Inversion 2), 9) introversional reorientation of the vector of cognitive activity (adaptive inversion 3).

The theory of evolution of complex and comprising of human systems and algorithm for its constructing are the synthesis of evolutionary epistemology, philosophical anthropology and concrete scientific empirical basis in modern (transdisciplinary) science. «Trans-disciplinary» in the context is interpreted as a completely new epistemological situation, which is fraught with the initiation of a civilizational crisis. Philosophy and ideology of technogenic civilization is based on the possibility of unambiguous demarcation of public value and descriptive scientific discourses (1), and the object and (...) subject of the cognitive process (2). Both of these attributes are no longer valid. For mass, everyday consciousness and institutional philosophical tradition it is intuitively obvious that having the ability to control the evolutionary process, Homo sapiens came close to the borders of their own biological and cultural identity. The spontaneous coevolutionary process of interaction between the «subject» (rational living organisms) and the «object» (material world), is the teleological trend of the movement towards the complete rationalization of the World as It Is, its merger with the World of Due. The stratification of the global evolutionary process into selective and semantic (teleological) coevolutionary and therefore ontologically inseparable components follows. With the entry of anthropogenic civilization into the stage of the information society, firsty, the post-academic phase of the historical evolution of scientific rationality began, the attributes of which are the specific methodology of scientific knowledge, scientific ethos and ontology. Bioethics as a phenomenon of intellectual culture represents a natural philosophical core of modern post- academic (human-dimensional) science, in which the ethical neutrality of scientific theory principle is inapplicable, and elements of public-axiological and scientific-descriptive discourses are integrated into a single logic construction. As result, hermeneutics precedes epistemology not only methodologically, but also meaningfully, and natural philosophy is regaining the status of the backbone of the theory of evolution – in an explicit form.

How should we make sense of pregnancy discrimination as an issue of gender equality? In a striking 1974 decision, Geduldig v. Aiello, the U.S. Supreme Court has answered that we simply cannot. Pregnancy discrimination does not constitute a form of sex discrimination prohibited by law, the 6–3 decision claims, because differential treatment based on pregnancy draws only a gender-neutral line between “pregnant women” and “nonpregnant persons,” not the gender line between women and men. While courts have since invoked Geduldig to (...) curtail both reproductive and transgender rights, the prevailing feminist response to this line of cases is still to double down on an awkwardly cissexist conception of gender, finding the sex discrimination in the “direct” way that pregnancy is thought to connect to womanhood. The failure of that prevailing feminist response, legitimizing rather than challenging biological essentialism in legal analysis and public discourse, epitomizes a broader failure of feminist analysis and intersectional solidarity: it fails to confront the political and social problem that is pregnancy discrimination for either cis or trans people. This essay offers a trans feminist alternative. I argue that pregnancy discrimination is discrimination on the basis of sex, within the legally relevant meaning of that phrase, not because pregnancy is in one way or another distinctive to women as a gender category but because pregnant persons make up a gender category of their own. On my analysis, pregnancy discrimination comes out as a form of sex discrimination directly and immediately, not by way of womanhood. (shrink)

Comentário Crítico. Referência do artigo comentado: LOPES, Marcelo Vieira. Para além da dúvida corporal: a dúvida como problema existencial e sua relevância para a psiquiatria. Trans/form/ação: Revista de Filosofia da Unesp, Marília, v. 47, n. 6, e02400329, 2024.

Popper's account of refutation is the linchpin of his famous view that the method of science is the method of conjecture and refutation. This thesis critically examines his account of refutation, and in particular the practice he deprecates as avoiding a refutation. I try to explain how he comes to hold the views that he does about these matters; how he seeks to make them plausible; how he has influenced others to accept his mistakes, and how some of the ideas (...) or responses to Popper of such people are thus similarly mistaken. I draw some distinctions necessary to the provision of an adequate account of the so-called practice of avoiding a refutation, and try to rid the debate about this practice of at least one red herring. I analyse one case of 'avoiding' a refutation in detail to show how the rationality of scientific practice eludes both Popper and many of his commentators. Popper's skepticism about contingent knowledge prevents him from providing an acceptable account of contingent refutation, and so his method is really the method of conjecture and conjecture. He cannot do without the concepts of knowledge and refutation, however, if his account of science is to be plausible or persuasive, and so he equivocates between, amongst other things, refutation as disproof and refutation as the weaker notion of discorroboration. I criticise David Stove's account of this matter, in particular to show how he misses this point. An additional advantage Popper would secure from this equivocation is that if refutations were mere discorroborations they would be easier to achieve, and hence more common in science, than is the case. On Popper's weak notion of refutation, it would be possible to refute true theories since corroboration does not entail truth. There are two other related doctrines Popper holds about refutation which, if accepted, make some refutations seem easier to obtain than is the case. I call these doctrines 'Strong Popperian Falsificationism' (SPF) and 'Weak Popperian Falsificationism' (WPF). SPF is the false doctrine that if a prediction from some theory is refuted then that theory is refuted. Popper does not always endorse SPF. In particular, when confronted with a counterexample to it, he retreats to WPF, which is the false doctrine that if a prediction from some theory is refuted then that theory is prima facie refuted. WPF , or even SPF, can seem plausible if one has in mind predictions derived from theories in strong or conclusive tests of those theories, which I suggest Popper characteristically does. v Popper is disposed to describe any such case of predictive failure which does not lead to the refutation of the theory concerned as one in which that refutation has been avoided. To reinforce his portrayal of the refutation, or the attempted refutation, of major scientific theories as the rational core of scientific practice, Popper treats the so-called practice of avoiding a refutation as untypical of science, and much so-called avoidance he dismisses as unscientific or pseudo-scientific. I argue that his notion of avoiding a refutation is incoherent. Popper is further driven to believe that such avoidance is possible, however, because he conflates sentences with propositions and propositions with propositional beliefs. Also, he wishes to avoid being saddled with the relativisim that is a consequence of his weak account of refutation as discorroboration. Popper believes that ad hoc hypotheses are the most important of the unscientific means of avoiding a refutation. I argue that his account of such hypotheses is also incoherent, and that several hypotheses thought to be ad hoc in his sense are not. Such hypotheses appear to be so largely because of Popper's use of rhetoric and partly because these hypotheses are unacceptable for other reasons. I conclude that to know that a hypothesis is ad hoc in Popper's sense does not illuminate scientific practice. Popper has also attempted to explicate ad hocness in terms of some undesirable, or allegedly undesirable, properties of hypotheses or the explanations they would provide. The first such property is circularity, which is undesirable; the second such property is reduction in empirical content, which is not. In the former case I argue that non-circularity is clearly preferable to non-ad hocness as a criterion for a satisfactory explanation or explanans, as the case may be, and in the latter case that Popper is barking up the wrong tree. Some cases of so-called avoidance are obviously not unscientific. The discovery of Neptune from a prediction based on the reasonable belief that there were residual perturbations in the motion of Uranus is an important case in point, and one that is much discussed in the literature. The manifest failure of astronomers to account for Uranus's motion did not lead to the refutation of Newton's law of gravitiation, yet significant scientific progress obviously did result. Retreating to WPF, Popper claims that Newton's law was prima facie refuted. In general, astronomers have never shared this view, and they are correct in not doing so. I argue that the law of gravitation would have been prima facie refuted only if there had been good reason at the time to believe as false what is true, namely, that an unknown trans-Uranian planet was the cause of those Uranian residuals. Knowledge of the trans-Uranian region was then so slight that it was merely a convenient assumption, one which there was little reason to believe was false, that the known influences on Uranus's motion were the only such influences. I conclude that in believing vi or supposing that it was this assumption that was false, rather than the law of gravitation, Leverrier and Adams, the co-predictors of Neptune, were acting rationally and intelligently. Popper's commentators offer a variety of accounts of the alleged practice of avoiding a refutation, and of this case in particular. I analyse a sample of their accounts to show how common is the acceptance of some of Popper's basic mistakes, even amongst those who claim to reject his falsificationism, and to display the effects on their accounts of this acceptance of his mistakes. Many commentators recognize that anomalies are typically dealt with by changes in the boundary conditions or in other of the auxiliary propositions employed. Where many still go wrong, however, is in retaining the presupposition of WPF which encouraged Popper to hold the contradictory view about anomalies in the first place. Thus Imre Lakatos and others, for example, have developed a 'siege mentality' about major scientific theories; they see them as under continual threat of refutation from anomalies, and so come to believe that dogmatism is essential in science if such theories are to survive as they do. I examine various such doomed attempts to reconcile Popper with the history of science. It is a common failure in this literature to conflate or to fail to see the need to distinguish a belief from a supposition, and an epistemic reason from a pragmatic reason. I argue that only if one does draw these distinctions can one give an adequate account of how anomalies are rationally dealt with in science. The other important strand in Popper's thinking about 'avoidance' of refutation which has seriously misled some of his commentators is his unfounded belief in the dangers of ad hoc hypotheses. I examine the accounts that a sample of such commentators provide of the trans-Uranian planet hypotheses of Leverrier and Adams. These commentators imply or assert what Popper only hints at, namely, that there is something fishy about this hypothesis. I provide a further defence of the rationality of entertaining this hypothesis at the time. I conclude with a few remarks about Popper's dilemma in respect of scientific practice and his long standing emphasis on refutations. (shrink)

RELAÇÃO E EFEITOS BIOQUÍMICO-NUTRICIONAIS SOBRE AS ALTERAÇÕES DO CORPO LÚTEO EM VACAS -/- Emanuel Isaque Cordeiro da Silva Departamento de Agropecuária – IFPE Campus Belo Jardim emanuel.isaque@ufrpe.br ou eics@discente.ifpe.edu.br WhatsApp: (82)98143-8399 -/- •__7. ALTERAÇÕES DO CORPO LÚTEO -/- A estrutura funcional desenvolve-se a partir da cavidade folicular após a ovulação. O corpo lúteo é constituído pelas células da teca interna (pequenas e ativas na primeira fase do seu desenvolvimento) e células da granulosa (grandes e ativas na segunda metade do seu (...) desenvolvimento). As principais características de cada tipo de célula podem resumir-se da seguinte forma: As células pequenas são mais sensíveis à ação da LH porque possui uma quantidade maior de receptores biologicamente ativos para esta hormona e a resposta é mediada pelo sistema AMPc-adelinato ciclase. As grandes células lúteas têm menos receptores para a LH (a maior quantidade são para a PGF2α e a PGE2), e são as responsáveis pela produção da oxitocina luteal (BAH, et al. 2006; CAMPO, 2003). Contrariamente às pequenas células lúteas, a produção de progesterona (P4) é parcialmente controlada pelo sistema Ca+2 - Fosfatil inositol-quinase C (CAMPO, 2003). A regulação da função do corpo lúteo é um mecanismo complexo. Nela intervêm fatores tróficos e líticos que estão presentes em forma simultânea durante todo o ciclo estral, e portanto a estimulação ou inibição da síntese e secreção de P4 depende do balanço entre estes fatores. (CAMPO, 2003). Dentro dos fatores tróficos, os nutrientes desempenham um papel relevante sobre a luteólise e as funções luteotrópicas, entre estas pode-se citar a ação das seguintes: -/- 7.1 Vitaminas Deficiência em betacarotenos. Vitamina A é um termo genérico que designa qualquer composto com atividade de retinol, o trans-retinol, é o composto base, sua forma aldeído e ácido são chamados de retinol e ácido retinóico, respectivamente. Por outro lado, a forma ativa da Vitamina A participa no mecanismo da visão, como 11-cis-retinal. Adicionalmente, o betacaroteno, considerado uma provitamina A é a única forma em que esta encontra nas plantas. Em sentido nutricional, a família da Vitamina A compreende todos os compostos que possuem atividade de retinol, incluindo cerca de cinquenta carotenoides que possuem atividade de provitamina A, aceitando-se que o mais ativo é o trans-betacaroteno (TORRES, et al. 2002). As vitaminas que são necessárias para o crescimento e a produção, também são essenciais para a reprodução. As recomendações atuais de vitamina A são de 75.000 UI/dia durante a lactação e 80.000 UI/dia (nota: 1 mg de Vitamina A = 400 UI) durante o período seco nas vacas leiteiras. A suplementação com vitamina A tem pouco risco de toxicidade, enquanto a sua deficiência pode retardar o aparecimento do primeiro cio/estro, induzir cios/estros silenciosos, aumentar o número de quistos ováricos, reduzir os índices de concepção, causar abortos, mortes embrionárias e ocasionar o nascimento de bezerros debilitados e fracos, uma vez que não irão nascer com os índices e requerimentos ideais de nutrientes passados da mãe para o feto pela placenta, e que, já que a mãe possui deficiência nutricional, o colostro não terá o efeito completo para passar a imunidade essencial ao neonato. Embora os mecanismos de ação não sejam claros, foram notificadas maiores secreções de esteroides ováricos quando as concentrações de β-carotenos no fluido folicular foram elevadas; logo, foram observadas maiores concentrações elevadas de β- estradiol e vitamina A nos folículos que terminaram em ovulação do que naqueles que terminaram em atresia. Para evitar as perdas reprodutivas por deficiência de vitamina A, pode-se optar pela administração oral ou injetável desta ao animal, mediante dois métodos: o primeiro consiste em adicionar 1 a 2,5 kg de premix vitamínico em 1 tonelada de grãos o que supre de 4 a 6.000 UI o que é desejável; o segundo é a administração via injetável em quantidades vide bula do fármaco. 7.2 Minerais O excesso de fósforo é absorvido principalmente no intestino delgado dos mamíferos através de um mecanismo de transporte ativo dependente do sódio, que é estimulado pela pró-hormona 1,25- hidroxivitamina D3. Os ruminantes são capazes de absorver o fósforo dietético em proporção direta às quantidades presentes na ração. Estima-se que aproximadamente 1% do corpo animal é composto de fósforo, do qual 85% está presente nos dentes e no tecido ósseo. Os tecidos moles são capazes de conter entre 0,15-0,20% de fósforo sob a forma de fosfoproteínas, nucleoproteínas, fosfolipídios, fosfato creatinina, adenosintrifosfato, glicose-6-fosfato, etc. Ao nível do plasma sanguíneo, o fósforo apresenta valores de 12,09 mg/dl. Os valores plasmáticos de fósforo são regulados principalmente pelo rim, sendo observado um aumento na excreção urinária do elemento inorgânico quando este excede a capacidade de transporte (REBOLLAR & MATEOS, 1999). O fósforo faz parte dos fosfolipídios, que são importantes no transporte de lipídios e seu metabolismo, como componente das membranas celulares. O fosfato faz parte do RNA e do DNA, componentes celulares vitais, e são essenciais para a síntese proteica. O fosfato faz parte de sistemas enzimáticos como a cocarboxilase e NAD, portanto está envolvido em todos os processos de síntese e regulação energética, dado que o corpo lúteo requer altas quantidades de energia para a síntese celular e hormonal, um excesso de fósforo pode bloquear a capacidade renal da sua regulação gerando um desequilíbrio catiônico que descompensa a relação Na:K, já que deverão ser excretados íons fosfato para regular o equilíbrio ácido-básico, desta forma, os processos celulares em tecidos de alta sensibilidade como o ovário serão afetados em sua função. A situação para prevenção de problemas relacionados ao fósforo (P) já foi tratada em assuntos anteriores, porém, sempre vale frisar para o leitor fiel que me lê que as exigências de P presentes na matéria seca (MS) variam entre 0,17 e 0,59% de P por kg/MS para bovinos de corte e em 0,32 a 0,44% por kg/MS para o gado leiteiro. Dessa forma, dados obtidos por pesquisas, ditam que para a mantença de uma vaca ou quaisquer outra categoria bovina o ideal é o consumo de 1.43 g/100 kg de peso vivo (PV), garantindo assim a prevenção de possíveis afecções reprodutivas como as alterações do corpo lúteo. Gramíneas, forragens, leguminosas e os concentrados fornecem muito bem os requerimentos de fósforo para os animais, todavia deve-se estar atento as relações e dependências do P com outros elementos como o Ca e a relação Na:K (10-15:1 idealmente). 7.3 Compostos estrogênicos Os fitoestrogênios afetam repetidamente a estabilidade do corpo lúteo. Os compostos estrogênicos encontrados principalmente em leguminosas pertencem principalmente a três grupos: isoflavanos, isoflavonas, presentes no gênero Trifolium e praticamente restritos às leguminosas, e cumestanos, que foram estudados na alfafa (Medicago sativa) e na Melilotus alba. Todas as isoflavonas sofrem algum grau de transformação no rúmen, sendo o Isoflavonoide formononetina, na realidade um pró-estrógeno, o único que se ativa no ecossistema ruminal ao ser convertido em equol, enquanto que as demais são degradadas a produtos inativos (RAMOS, et al. 1998). Por fim, a alta concentração no sangue do equol retarda a retroalimentação sobre a hipófise mediante a qual se reduzem os níveis de FSH para dar lugar à onda ovulatória de LH, se esta não ocorrer, o corpo lúteo obviamente não se formará. O conhecimento acerca dos estrogênios na alimentação animal é defasado nos livros sobre o tema, no entanto, o criador pode ficar tranquilo no que tange o tema na prática da sua fazenda e dos seus animais, uma vez que tal elemento é muito bem fornecido naturalmente por meio dos alimentos volumosos presentes no seu pasto. -/- Apoio -/- Realização -/- REFERÊNCIAS BIBLIOGRÁFICAS BAH, Mamadou M. et al.

Rapid urbanization in Vietnam significantly impacts the environment and human well-being. Public parks are crucial for enhancing social and environmental sustainability in urban areas, yet their establishment and expansion require substantial funding. This study investigates the factors influencing Vietnamese urban residents’ willingness to donate to planting projects in public parks, utilizing the Bayesian Mindsponge Framework (BMF), which combines Mindsponge Theory’s informational entropy-based notion of value with Bayesian analysis. Analyzing data from 535 residents in major Vietnamese cities, we found that while (...) men visit public parks more frequently, they are less willing to donate to planting projects. Older residents visit parks more often and are more willing to donate, while higher-income individuals show greater willingness to donate. Most motivations—such as relaxation, physical activities, nature enjoyment, socializing, and family time—are positively linked to park visit frequency and indirectly to donation willingness. However, only relaxation and enjoyment of nature are directly associated with willingness to donate. Interestingly, higher education levels and visiting parks for children’s educational activities are associated with lower donation willingness. These findings hint at the possible existence of the free-riding problem, gender inequality, ineffective environmental education, and lack of awareness of public parks’ natural value, as well as opportunities to cultivate an eco-surplus culture through nature interactions in public parks.

In the first part of this article we survey general similarities and differences between biological and social macroevolution. In the second (and main) part, we consider a concrete mathematical model capable of describing important features of both biological and social macroevolution. In mathematical models of historical macrodynamics, a hyperbolic pattern of world population growth arises from non-linear, second-order positive feedback between demographic growth and technological development. Based on diverse paleontological data and an analogy with macrosociological models, we suggest that the (...) hyperbolic character of biodiversity growth can be similarly accounted for by non-linear, second-order positive feedback between diversity growth and the complexity of community structure. We discuss how such positive feedback mechanisms can be modelled mathematically. (shrink)

Review the Istvan Kiraly V.'s book: Death and History.

Parental environmental education in early childhood is vital for nurturing environmental awareness and ecological protection. This study investigates how parents’ nature engagement methods influence children’s environmental awareness and participation in protection activities. Using the Bayesian Mindsponge Framework with data from 516 children and their primary caregivers across 23 elementary summer schools in five urban Chinese cities, the findings reveal varying impacts of parental engagement methods. Raising animals and plants is positively associated with environmental awareness (moderate reliability) and protection activities (high (...) reliability). Visiting museums about endangered and extinct species enhances children’s environmental awareness, while learning about insects and their habits improves their participation in protection activities (both high reliability). However, outdoor learning experiences and playing in natural environments (e.g., parks and forests) show ambiguous effects. These results underscore the value of family-centered environmental education, emphasizing the crucial roles of direct nature interactions and providing actionable insights for child-focused environmental policies.

The split, the alienation of philosophy from the sciences occurred long before all sorts of perestroikas and KGB revolutions "from above", all these great leaps, great pushes and painful kicks. This is a consequence of internal processes occurring at the level of everyday scientific consciousness, the living practice of scientific research. The isolation of development is a fact, not an invention of the Mossad or the CIA. It was precisely from this fact that we proceeded when we conceived this conference. (...) Philosophers and representatives of specific sciences should meet in order to speak on equal terms, as equals with equals, in order to possibly learn something from each other. Concrete scientists could not only enrich philosophers with new material, but also pose a number of problems for them. The novelty is that the philosophical approach is recognized as existing not above others, but alongside them, as a kind of reflection on the foundations of these approaches, analysis, digging into the theoretical and conceptual side of the matter.

Maurice Merleau – Ponty is a French philosopher and political activist with close ties to Tran Duc Thao. The two not only had a relationship between teachers and students and colleagues at the ENS Paris - where Tran Duc Thao studied and worked, but also participated in the magazine Les Temps modernes. Merleau - Ponty's thought is therefore one of the sources of thought that has a great influence on Tran Duc Thao's philosophy. However, Tran Duc Thao's philosophical views, in (...) phenomenology, dialectical materialism and in socio-political concepts, have striking similarities and differences with Merleau - Ponty's thought.

As a generation of ‘digital natives,’ secondary students who were born from 2002 to 2010 have various approaches to acquiring digital knowledge. Digital literacy and resilience are crucial for them to navigate the digital world as much as the real world; however, these remain under-researched subjects, especially in developing countries. In Vietnam, the education system has put considerable effort into teaching students these skills to promote quality education as part of the United Nations-defined Sustainable Development Goal 4 (SDG4). This issue (...) has proven especially salient amid the COVID−19 pandemic lockdowns, which had obliged most schools to switch to online forms of teaching. This study, which utilizes a dataset of 1061 Vietnamese students taken from the United Nations Educational, Scientific, and Cultural Organization (UNESCO)’s “Digital Kids Asia Pacific (DKAP)” project, employs Bayesian statistics to explore the relationship between the students’ background and their digital abilities. Results show that economic status and parents’ level of education are positively correlated with digital literacy. Students from urban schools have only a slightly higher level of digital literacy than their rural counterparts, suggesting that school location may not be a defining explanatory element in the variation of digital literacy and resilience among Vietnamese students. Students’ digital literacy and, especially resilience, also have associations with their gender. Moreover, as students are digitally literate, they are more likely to be digitally resilient. Following SDG4, i.e., Quality Education, it is advisable for schools, and especially parents, to seriously invest in creating a safe, educational environment to enhance digital literacy among students.

Wildfires have become an increasing global threat to public health and quality of life. Many countries employ air quality monitoring and reporting systems to mitigate health risks associated with air pollution, including wildfire smoke. This study investigates the factors influencing individuals’ sensitivity to air quality information, specifically their likelihood of reducing or ceasing outdoor activities in response to air quality ratings, with a focus on wildfire smoke exposure in the western United States. Using the Bayesian Mindsponge Framework (BMF) analytics, the (...) study analyzed data from 2,237 participants in the Boise Metropolitan Area of Idaho and Boise State University. The findings reveal that women, older individuals, and those with higher educational levels are more likely to reduce outdoor activities at lower unhealthy AQI levels (the lowest being ‘good air quality,’ while the highest being ‘hazardous air quality’), while individuals with higher incomes are less responsive. Women and older adults, in particular, are even more likely to eliminate all outdoor activities. Additionally, individuals who perceive wildfire smoke as more severe than other natural disasters are more inclined to reduce or eliminate outdoor activities at lower unhealthy air quality levels. Experiences of wildfire smoke-related illness—either personally or within their households—further amplify this effect. These findings highlight the importance of localized, context-specific approaches to AQI dissemination and wildfire smoke risk communication to build resilience and safeguard public health in the face of escalating wildfire challenges driven by climate change.

White-nose syndrome (WNS), a lethal disease driven by the fungal pathogen Pseudogymnoascus destructans (Pd), has decimated bat populations across North America since its arrival in 2006 [2]. A recent global assessment warns that this pathogen could soon threaten bat species in the Southern Hemisphere, where evolutionary naïveté and suitable environmental conditions heighten the risk of a widespread outbreak [3].

The analysis of moral subject in consequentialist ethics (as a kind of nonutilitaristic consequentialism) aims to show, that moral subject is of basie importance for it - regardeless to the fact, that its analysis focuses predominantly on action and its concequences. It is the moral subject, which enables the action and its consequences to be performed. So understanding the conditions of moral subjecťs action means understanding the moral subject itself. This understanding draws upon the typology of moral subjects that makes (...) the prediction of certain kinds of action as well as oftheir consequencies possible. (shrink)

What is the value of a lightning bolt? A strange question, perhaps. But as it arcs across the sky, that bolt is doing something remarkable: it's fixing nitrogen from the air, making it available to plants in a process that took nature billions of years to evolve. If we tried to replicate this service industrially, it would cost millions. Yet, in our economic systems, that lightning bolt is worth exactly zero dollars and zero cents. This paradox sits at the heart (...) of our troubled relationship with nature. For centuries, we have tried to squeeze the infinite complexity of the natural world into the finite box of market prices. But as climate change accelerates and biodiversity collapses, it is becoming clear that our economic models are not just incomplete – they are actively dangerous. A new paradigm is emerging in the interdisciplinary of biology, physics, information science, and quantum theory, offering fresh perspectives on how we might better understand and measure value.

As climate change drives unprecedented ecological transformations, traditional conservation approaches grounded in historical baselines are becoming increasingly untenable. The resist–accept–direct (RAD) framework offers a structured response, guiding land managers to either resist ecological changes, accept them, or direct ecosystems toward new, sustainable trajectories [2,3]. In their recent study, Cravens et al. [4] argue that the feasibility of these strategies is not fixed but evolves alongside dynamic social, regulatory, financial, and organizational contexts.

Like other books of Dr. Vuong, I always had a good laugh and an intellectually stimulating time after reading his book. -/- As someone who has experienced the frustrations of government procedures, the “culture” of doing research, or the poor and crowded streets in Vietnam, I found Dr. Vuong’s observation both hilarious and poignant. This ability to tackle these everyday annoyances with humor and turn them into opportunities for reflection is truly masterful.

In the way that First Born and the grizzly bear woman once shared a home, or the young girl who happily married the python man, perhaps conservation and preservation is about nurturing and sustaining relationships–relationships of reciprocity, respect, and shared existence with all living beings. Indigenous knowledge reminds us that humans are not separate from nature but integral to its fabric. As we are facing environmental crises like climate change and biodiversity loss, Indigenous knowledge and traditional practices offer a pathway (...) toward a more sustainable and harmonious future founded on respect, reciprocity, and responsibility.

Khi biến đổi khí hậu thúc đẩy những thay đổi sinh thái chưa từng có, các phương pháp bảo tồn truyền thống dựa trên các đường chuẩn lịch sử ngày càng trở nên khó khả thi.

Abstract In this chapter, we challenge the presupposed concept of innovation in the responsible innovation literature. As a first step, we raise several questions with regard to the possibility of ‘responsible’ innovation and point at several difficulties which undermine the supposedly responsible character of innovation processes, based on an analysis of the input, throughput and output of innovation processes. It becomes clear that the practical applicability of the concept of responsible innovation is highly problematic and that a more thorough inquiry (...) of the concept is required. As a second step, we analyze the concept of innovation which is self-evidently presupposed in current literature on responsible innovation. It becomes clear that innovation is self-evidently seen as (1) technological innovation, (2) is primarily perceived from an economic perspective, (3) is inherently good and (4) presupposes a symmetry between moral agents and moral addressees. By challenging this narrow and uncritical concept of innovation, we contribute to a second round of theorizing about the concept and provide a research agenda for future research in order to enhance a less naïve concept of responsible innovation.

Indigenous territories (ITs) are vital to preserving the Amazon’s biodiversity and carbon stocks. Yet, conventional conservation approaches often overlook the intricate cultural and political connections that unify these lands [2]. Esbach et al. [3] introduce the concept of Archipelagos of Indigenous Territories (AITs)—networks of spatially distinct but culturally and politically linked ITs—as a critical framework for advancing conservation efforts in the region.

In this conceptual paper, the traditional conceptualization of sustainable entrepreneurship is challenged because of a fundamental tension between processes involved in sustainable development and processes involved in entrepreneurship: the concept of sustainable business models contains a paradox, because sustainability involves the reduction of information asymmetries, whereas entrepreneurship involves enhanced and secured levels of information asymmetries. We therefore propose a new and integrated theory of sustainable entrepreneurship that overcomes this paradox. The basic argument is that environmental problems have to be conceptualized (...) as wicked problems or sustainability-related ecosystem failures. Because all actors involved in the entrepreneurial process are characterized by their epistemic insufficiency regarding the solving of these problems, the role of information in the sustainable entrepreneurial process changes. On the one hand, the reduction of information asymmetries primarily aims to enable actors to become critical of sustainable entrepreneurs’ actual business models. On the other hand, the epistemic insufficiency of sustainable entrepreneurs guarantees that information asymmetries remain as a source of new sustainable business opportunities. Three further characteristics of sustainable entrepreneurs are distinguished: sustainability and entrepreneurship-related risk-taking; sustainability and entrepreneurship-related self-efficacy; and the development of satisficing and open-ended solutions, together with multiple stakeholders.

The interdisciplinary economics book “Better Economics for the Earth: A Lesson from Quantum and Information Theories” by Prof. Quan-Hoang Vuong and Dr. Minh-Hoang Nguyen introduces a new concept of “growth” and “eco-surplus culture,” aiming toward an economic system that “heals” the Earth.

Corporate bond appeared in 1992-1994 in Vietnamese capital markets. However, it is still not popular to both business sectors and academic circles. This paper explores different dimensions of Vietnamese corporate bond market using a unique and perhaps, most complete data set. State not only intervenes in the bond markets with its powerful budget and policies but also competes directly with enterprises. The dominance of state-owned enterprises and large corporations also prevents small and medium enterprises from this debt financing vehicle. Whenever (...) a convertible term is available, bondholders are more willing to accept lower fixed income payoff. But they would not likely stick to it. On the one hand, prospective bondholders could value the holdings of equity when realized favourably ex ante. On the other hand, the applicable coupon rate for such bonds could turn out negative inflation-adjusted payoff when tight monetary policy is exercised and the corresponding equity holding turns out valueless, ex post. Given the weak primary market and virtually non-existent secondary market, the corporate bond market in Vietnam reflects our perception of the relationship-based and rent-seeking behaviour in the financial markets. For the corporate bonds to really work, they critically need a higher level of liquidity to become truly tradeable financial assets. Updated entries in 2010 affirm the findings and conclusions.

Contrary to the tendency to harmony, consensus and alignment among stakeholders in most of the literature on participation and partnership in corporate social responsibility and responsible innovation practices, in this chapter we ask which concept of participation and partnership is able to account for stakeholder engagement while acknowledging and appreciating their fundamentally different judgements, value frames and viewpoints. To this end, we reflect on a non-reductive and ethical approach to stakeholder engagement, collaboration and partnership, inspired by the philosophy of Emmanuel (...) Levinas. We contrast a cognitive approach with an ethical approach to stakeholder engagement, collaboration and partnership, and explore four characteristics of this ethical approach. Based on the ethical approach to stakeholder engagement, collaboration and partnership, we also provide a three-stage framework for partnership formation in CSR and RI practices. (shrink)
