Awarding rights to rivers, forests, and other environmental entities (EEs) is a new and increasingly popular approach to environmental protection. The distinctive feature of such rights of nature (RoN) legislation is that direct duties are owed to the EEs. This paper presents a novel rebuttal of the strongest argument against RoN: the no interest argument. The crux of this argument is that because EEs are not sentient, they cannot possess the kinds of interests necessary to ground direct duties. Therefore, they (...) cannot be legitimate rights-bearers. After considering and rejecting standard responses to this argument, the paper challenges its fundamental assumption: that rights-correlative duties must be grounded in the interests of the rights-bearer. The paper then presents the RoN critic with a dilemma. The critic must either accept that EEs are legitimate rights-bearers, or delegitimise many well-established rights-bearers along with EEs. Either way, the no interest argument loses its force. (shrink)

In this article, we describe a project in which philosophy, in combination with methods drawn from mental modeling, was used to structure dialogue among stakeholders in a region-scale climate adaptation process. The case study we discuss synthesizes the Toolbox dialogue method, a philosophically grounded approach to enhancing communication and collaboration in complex research and practice, with a mental modeling approach rooted in risk analysis, assessment, and communication to structure conversations among non-academic stakeholders who have a common interest in planning for (...) a sustainable future. We begin by describing the background of this project, including details about climate resiliency efforts in West Michigan and the Toolbox dialogue method, which was extended in this project from academic research into community organization involving the West Michigan Climate Resiliency Framework Initiative. This extension involved application of several methods, which are the focus of the Methods section. We then present and discuss preliminary results that suggest the potential for philosophical dialogue to enhance mutual understanding in complex community initiatives that focus on sustainable responses to climate change. Overall, the article supplies a detailed, instructive example of how philosophy can support policy-relevant decision-making processes at the community level. (shrink)

Within much contemporary social ontology there is a particular methodology at work. This methodology takes as a starting point two or more asocial or atomic individuals. These individuals are taken to be perfectly functional agents, though outside of all social relations. Following this, combinations of these individuals are considered, to deduce what constitutes a social group. Here I will argue that theories which rely on this methodology are always circular, so long as they purport to describe the formation of all (...) social groups, as they must always presuppose a pre-existing collectivity. Such methodology also produces various distortions in our theories, such as voluntarism. I focus on the workings of Plural Subject Theory as laid out by Margaret Gilbert in On Social Facts. I show that the formation of a plural subject always requires communication, and that communication always requires a pre-existing collectivity. i examine the elements within Plural Subject Theory which protect gilbert from these accusations of circularity, and argue against them. I finalise by suggesting that what Plural Subject Theory, and social ontology in general, requires as a theoretical starting point is not atomic individuals and their combinations, but rather combinations of already socialised or embedded individuals.

In this chapter, we compare Kant and James’ accounts of freedom. Despite both thinkers’ rejecting compatibilism for the sake of practical reason, there are two striking differences in their stances. The first concerns whether or not freedom requires the possibility of an open future. James holds that morality hinges on the real possibility that the future can be affected by our actions. Kant, on the other hand, seems to maintain that we can still be free in the crucial sense, even (...) if none of our actions can have any effect on the future. The second difference between them is related, and concerns the location of freedom. Kant views experience as determined by natural necessity, and locates freedom outside of it, in things-in-themselves. James, on the other hand, has a richer conception of experience than Kant, and holds that we can locate our freedom within experience alone. In the end, we contend that James has a better account of how freedom relates to our experience, but this comes at a cost. For while Kant's account struggles with the relationship between freedom and experience, it has the advantage of insulating our freedom from potential empirical challenges. (shrink)

Trust not only disposes us to feel betrayed, trust can be betrayed. Understanding what a betrayal of trust is requires understanding how trust can ground an obligation on the part of the trusted person to act specifically as trusted. This essay argues that, since trust cannot ground an appropriate obligation where there is no prior obligation, a betrayal of trust should instead be conceived as the violation of a trust-based obligation to respect an already existing obligation. Two forms of trust (...) are evaluated for their potential to ground such a second-order obligation. One form counts as a gift to the trusted person only because it does not involve an expectation of trustworthiness; the other form cannot count as a gift but confers an honor because it does include an expectation of trustworthiness. Only trust that confers an honor generates a second-order obligation whose violation would be a betrayal of trust. -/- . (shrink)

Many oppose the use of profile evidence against defendants at trial, even when the statistical correlations are reliable and the jury is free from prejudice. The literature has struggled to justify this opposition. We argue that admitting profile evidence is objectionable because it violates what we call “equal protection”—that is, a right of innocent defendants not to be exposed to higher ex ante risks of mistaken conviction compared to other innocent defendants facing similar charges. We also show why admitting other (...) forms of evidence, such as eyewitness, trace, and motive evidence, does not violate equal protection. (shrink)

The representational theory of phenomenal experience is often stated in terms of a supervenience thesis: Byrne recently characterises it as the thesis that “there can be no difference in phenomenal character without a difference in content”, while according to Tye, “[a]t a minimum, the thesis is one of supervenience: necessarily, experiences that are alike in their representational contents are alike in their phenomenal character.” Consequently, much of the debate over whether representationalism is true centres on purported counter-examples – that is (...) to say, purported failures of supervenience. The refutation of putative counter-examples has been, it seems to me, by and large successful. But there is a certain class of these for which the representationalist response has been something less than completely convincing. These are the cross-modality cases. I will explain what I mean, and then argue that the response in question is not only unconvincing but actually undermines the representationalist position. (shrink)

Parents play a critical role in their child’s personal development and day-to-day experiences. However, as digital technologies are increasingly embedded in most New Zealand children’s everyday life activities parents face the task of ensuring their child’s online safety. To do so, they need to understand the way their child engages with and through these tools and make sense of the rapidly changing, and more technically complex, nature of digital devices. This presents a digital parenting dilemma: maximising children’s online opportunities while (...) minimising online risks and potential harm. This factsheet presents evidence about digital parenting in New Zealand based on nationally representative data collected from parents, caregivers and whānau and their children aged 9-17. It uses measures from the Global Kids Online project to explore the prevalence of different practices used by New Zealand parents to influence or mediate children’s internet use. (shrink)

Living organisms are exposed to numerous influencing factors. This holds also true for their infrastructures that are processing and transducing information like endocrine networks or nerval channels. Therefore, the ability to compensate for noise is crucial for survival. An efficient mechanism to neutralise disturbances is instantiated in form of parallel complementary communication channels exerting antagonistic effects at their common receivers. Different signal processing types share the ability to suppress noise, to widen the system’s regulation capacity, and to provide for variable (...) gains while leaving the transferred signal to a large extent unchanged.

It is true now that man lives in a world of conflict. Conflict is an ever-present process in human relations. Conflict situations indeed appear frequently in daily, public and private life. Conflict may occur within and among families, groups, communities or nations; and they may be fuelled by ethnic, racial, religious, or economic differences, or may arise from differences in ideologies, values and beliefs. Conflict may be on a small or large scale. Conflict charge the people with tensions, threats, fears, (...) anxieties and uncertainties. What makes a society ideal is the extent to which the conflicting interests and needs in a society are constructively managed so that violence does not threaten its continued existence. Since it is obvious that conflicts in any given society is inevitable, management and resolution of conflict is the very essence of talking about conflict. This is what this work is set to achieve and to offer suggestions on how to manage and resolve conflict thereby reducing its negative and destructive effects. This work showed the church has the potential to contribute to the management and resolution of conflicts in Nigeria. (shrink)

While children’s experiences of online risks and harm is a growing area of research in New Zealand, public discussion on the matter has largely been informed by mainstream media’s fixation on the dangers of technology. At best, debate on risks online has relied on overseas evidence. However, insights reflecting the New Zealand context and based on representative data are still needed to guide policy discussion, create awareness, and inform the implementation of prevention and support programmes for children. This research report (...) presents findings from a quantitative study regarding different aspects related to risks and online safety. It looks at the online experiences that children find bothersome and upsetting and explores the hurtful behaviours they encounter or engage in, both online and in person. Evidence regarding exposure to different types of potentially harmful online content is also presented. Another relevant contribution is the insights related to excessive internet use.The findings presented in this report are based on data from 2,061 New Zealand children aged 9-17. We hope the findings will contribute to the development of policies, practices and services designed to support New Zealand children to safely take advantage of the opportunities available to them online.

This report is part of Netsafe’s research project Ngā taiohi matihiko o Aotearoa - New Zealand Kids Online, and our first publication as a member of Global (...) Kids Online. Generating insightful, reliable evidence about New Zealand children’s online experiences is vital to develop adequate support that reflects children’s experiences and needs. This, in turn, will help them to manage online risks and potential harm from behaviours such as cyberbullying, harassment, and other forms of abuse and intimidation. (shrink)

We introduce and consider the inner-model reflection principle, which asserts that whenever a statement \varphi(a) in the first-order language of set theory is true in the set-theoretic universe V, then it is also true in a proper inner model W \subset A. A stronger principle, the ground-model reflection principle, asserts that any such \varphi(a) true in V is also true in some non-trivial ground model of the universe with respect to set forcing. These principles each express a form of width (...) reflection in contrast to the usual height reflection of the Lévy–Montague reflection theorem. They are each equiconsistent with ZFC and indeed \Pi_2-conservative over ZFC, being forceable by class forcing while preserving any desired rank-initial segment of the universe. Furthermore, the inner-model reflection principle is a consequence of the existence of sufficient large cardinals, and lightface formulations of the reflection principles follow from the maximality principle MP and from the inner-model hypothesis IMH. We also consider some questions concerning the expressibility of the principles. (shrink)

Research suggests that parents tend to largely underestimate their child’s engagement in risky and/or hurtful behaviours as well as their experiences of harm online. While helpful, the available international evidence is not only limited but also does not reflect the New Zealand context. In addition, understanding parental knowledge of the online experiences of children is important as parents play a critical role in helping their child to prevent or deal with bothering experiences and risky behaviours as well as providing children (...) with emotional support when things go wrong online. To help close the gap of New Zealand-based evidence on the topic, this factsheet presents findings from a quantitative study conducted with New Zealand parents and their children. The objectives of the study are to measure parental knowledge of children’s experiences of risks and harm online, and to compare parents’ level of awareness with their child’s self-reported experiences. The study found a mismatch between parents’, caregivers’ and whānau awareness and their children’s reports of bothering or upsetting experiences online. (shrink)

As schools publicly modernize in response to societal changes, additional teaching and learning methods are developed, observed, and used since learners have different learning styles that make it easier for them to grasp and retain the material. During the COVID-19 pandemic, teachers require different media to keep the classroom involved while presenting the lesson materials online, one of which is video tutorials. The purpose of this study was to analyze the extent of contextual effects of video tutorials used in general (...) chemistry, determine the relationship between video tutorial effectiveness and the respondents' academic performance, and analyze the significant difference between the four indicators of contextual effects of video tutorials and the respondents' profile. A descriptive-correlational quantitative research design was used in this study. The participants in this study were 144 Grade 12 STEM students from a private school in Sultan Kudarat, Philippines, who took their general chemistry course during the pandemic. The respondents were given a survey questionnaire created with Google Forms. The students agreed with all the assertions and rated them as effective in terms of their perceptions of general chemistry, implying that video tutorials are useful in teaching the subject. With p-values of .023, .046, and .010, respectively, the findings revealed a significant relationship between the overall mean of students' perceptions of the subject of General Chemistry, the concept and application of chemical knowledge and understanding, and their influence on students' academic performance. In terms of their perception, ideas, and application of chemical knowledge and comprehension, the results demonstrated that there is no statistically significant difference between the general mean of male and female students' responses. This basically means that by using video lectures, STEM students of all genders appreciate and understand General Chemistry as a subject. -/- . (shrink)

In this paper, we attempt to show that if Plantinga’s free will defence succeeds, his O Felix Culpa theodicy fails.

This study aims to generate thorough and comprehensive review of the teacher’s perspective and hands-on experience in mainstreaming LSENs in a regular classroom, including teachers’ attitudes and perceptions, challenges encountered, and teaching approach in handling mainstreamed classrooms. A scoping review framework by Arksey and O’Malley’s (2005) systematically analyzed the data of the different articles conducted by various scholars. Through scrupulous and through selection of related studies, 10 articles were included in the review from 6 different countries across the globe. The (...) articles included were conducted from 6 countries and various databases. The study highlighted that: 1) teachers have positive and negative attitudes towards mainstreaming, 2) teachers experienced various challenges in handling a mainstream classroom, and 3) learner-centered approach to learning is used in the classroom. Mainstreaming LSENs in a regular classroom has pros and cons among teachers, regular students, and the LSENs themselves. Hence, a daunting responsibility for the teachers. Nevertheless, it is imperative to support teachers by giving seminars and training, especially to those non-special education majors, to be fully equipped to handle mainstreamed classrooms. (shrink)

DESENVOLVIMENTO EMBRIONÁRIO E DIFERENCIAÇÃO SEXUAL -/- E. I. C. da Silva Departamento de Agropecuária – IFPE Campus Belo Jardim Departamento de Zootecnia – UFRPE sede -/- 1.1 INTRODUÇÃO O sexo foi definido como a soma das diferenças morfológicas, fisiológicas e psicológicas que distinguem o macho da fêmea permitindo a reprodução sexual e assegurando a continuidade das espécies. Os processos de diferenciação sexual são realizados durante o desenvolvimento embrionário, onde ocorre a proliferação, diferenciação e maturação das células germinativas e primordiais, precursoras (...) de ovócitos e espermatozoides em fêmeas e machos, respectivamente. Assim, os embriões machos e fêmeas iniciam o seu desenvolvimento de forma semelhante, de modo que em ambos os sexos se estabelecem em estruturas idênticas a partir das quais se formarão os órgãos reprodutores correspondentes a cada sexo. O conhecimento da origem e do desenvolvimento do aparelho genital é indispensável para entender sua função e as alterações que produzem infertilidade ou esterilidade. 1.2 DETERMINAÇÃO DO SEXO CROMOSSÔMICO Nos mamíferos, o sexo cromossômico é determinado no momento da fertilização, quando um óvulo, que contém um cromossomo X, é fecundado por um espermatozoide portador de um cromossomo X ou um cromossomo Y. No primeiro caso, o complemento cromossômico seria XX, o que originaria uma fêmea (sexo homogamético), e no segundo daria como resultado um macho com a fórmula cromossômica XY (sexo heterogâmico). 1.3 A GÔNADA INDIFERENCIADA A primeira manifestação das gônadas se aprecia no embrião em forma de um par de eminências longitudinais chamadas cristas ou dobras gonodais, situadas em ambos os lados da linha média entre os mesonefros (rins em desenvolvimento) e do mesentério dorsal. Nos embriões dos mamíferos, as células germinativas primordiais (CGP) manifestam-se em estágios precoces do desenvolvimento, podendo ser detectadas pela primeira vez na metade da gastrulação. As CGP são células grandes, de citoplasma claro e núcleo grande e redondo, localizadas na parede do saco vitelino, perto do alantoide. Essas células possuem grande capacidade de proliferação e vão migrar desde o endoderma do intestino e o epitélio do saco vitelino, através do mesentério, até as cristas gonodais. Isso ocorre por volta do 26° dia da gestação no bovino. Sua migração realiza-se graças aos movimentos de translocação passiva e deslocamento ameboide ativo. Desconhece-se o mecanismo pelo qual estas células são dirigidas para as cristas gonodais, porém foram estudadas algumas moléculas que se expressam durante sua migração e que poderiam desempenhar um papel importante na diferenciação deste tipo celular. A fosfatase alcalina é uma enzima que tem sido usada como marcador de CGP para determinar a sua origem e migração. Num estudo recente, foi inserido um marcador fluorescente que se exprime unicamente nas células germinativas primordiais de embriões transgênicos, e utilizando este marcador e a fosfatase alcalina determinou-se a origem e o padrão de migração destas células. O primeiro sinal de diferenciação das células germinativas primordiais é a expressão de fosfatase alcalina, e esta apareceu pela primeira vez na parte mais posterior da linha primitiva. No sétimo dia de desenvolvimento no embrião do camundongo, o endoderma visceral (AF+) é substituído pelo endoderma definitivo (AF-) originado na parte anterior da linha primitiva. O fator de transcrição Oct-4 é expresso nas CGP de ambos os sexos, pelo que acredita-se estar envolvido na mantença a totipotêncialidade das células. O receptor tirosina quinase, cujo ligante é o fator de Steel, é outra das moléculas que expressam as CGP. Tem sido demonstrado que este receptor possui um papel muito importante na sobrevivência deste tipo celular. Existem outros fatores que promovem a sobrevivência e/ou proliferação de CGP in vitro. Em experiências realizadas com o fator de transformação beta I (TGFβ-I), observou-se que este tem um efeito negativo sobre a proliferação das CGP. Outra atividade que tem sido postulada a este fator é o de um agente quimioatraente que possivelmente possa direcionar a migração destas células para a gônada. a) Um formado pelas células germinativas primordiais (precursoras dos gametas masculinos ou femininos), rodeadas de células somáticas das quais posteriormente se derivarão as células de Sertoli no macho e as células da granulosa na fêmea. b) O tecido que formará o estroma da gônada: tecido conjuntivo, vasos sanguíneos e as células intersticiais com atividade esteroidogênica (células de Leydig no testículo e a teca interna do ovário). As células somáticas do primórdio gonodal originam-se do mesoderma. Inicialmente são de três tipos: mesenquimáticas, mesoteliais e endoteliais. As células mesenquimáticas e mesoteliais iniciam grande atividade proliferativa ao chegar as CGP. Observa-se então uma condensação de células de origem mesotelial e mesenquimatoso que forma um agregado compacto denominado "blastema gonodal". A partir deste primórdio embrionário, diferenciam-se dois tecidos gonodais: os cordões sexuais e o estroma. Os cordões sexuais são arranjos epiteliais que se encontram delimitados por uma folha basal, e dentro deles encontramos as CGP. Por sua vez, no estroma encontram-se células do tipo mesenquimático e vasos sanguíneos. Neste momento, as gônadas são indiferenciadas e bipotencialmente sexuais, sendo impossível diferenciar, morfologicamente, uma gônada masculina de uma feminina, mas no caso dos machos genéticos já existe uma diferenciação da gônada a nível molecular. Nesta fase já se encontram presentes as estruturas das quais se desenvolvem os dutos mesonéfricos ou de Wolff precursores do aparelho genital masculino e os dutos paramesonéfricos ou de Müller que darão origem ao aparelho reprodutor feminino. Há uma série de fatores envolvidos no desenvolvimento precoce da gônada, entre os quais o fator esteroidogênico I (SFI: Steroidogenic fator l), que é um membro da subfamília de receptores nucleares, receptores órfãos. Este fator de transcrição tem um local de ligação ao DNA composto por dois dedos-de-Zinc. O SFI foi identificado como um ativador de genes envolvidos na biossíntese de esteroides em diferentes células. O SFI está presente durante o desenvolvimento embrionário em regiões associadas com funções endócrinas como gônadas, adrenais, pituitárias e hipotálamos. Os animais homozigotos para o gene SFI defeituoso, necessitam de gônadas e adrenais e têm a função gonadotrófica alterada. Os ratos sem SFI carecem de gonadotrofos e têm um desenvolvimento anormal do núcleo ventro-medial do hipotálamo; em particular as gônadas deixam de se desenvolver entre os dias 11 a 15 e degeneram-se por apoptose. No entanto, a crista genital forma-se e é colonizada pelas células germinativas, o que indica que estas continuam a receber o sinal adequado para a sua migração. Portanto, o SFI não está envolvido no desenvolvimento precoce da gônada e do sistema urogenital, mas parece estar envolvido na manutenção do crescimento das células somáticas presentes na gônada indiferenciada. O gene associado ao tumor de Wilms (WTI: Wilm's tumor Associated) está envolvido no desenvolvimento da gônada e do rim. Durante o desenvolvimento embrionário, WTI se expressa em todo o mesoderma intermediário e posteriormente na gônada indiferenciada, bem como no rim em formação. WTI regula o sinal indutivo do mesênquima para o epitélio celômico dos mesonefros. Se este for o caso, então WTI é responsável pelo crescimento da crista genital ao dirigir a entrada do epitélio celômico. Dado que estas células darão origem às células de Sertoli, a carência de WTI pode causar o desenvolvimento de embriões XY como fêmeas simplesmente porque não se formam as células de Sertoli. Em geral, todos os genes importantes na diferenciação do mesoderma intermediário e do sistema urogenital intervêm no desenvolvimento da gônada precoce. 1.4 DIFERENCIAÇÃO GONODAL O desenvolvimento das gônadas e ductos genitais descritos até o momento, é o mesmo para ambos os sexos. Igualmente, os genes descritos, que estão envolvidos no desenvolvimento das gônadas, ductos genitais e migração das células germinativas, afetam igualmente os embriões com genótipo XX ou XY. A gônada primitiva consiste anatomicamente de uma medula (interna) e uma crosta (externa), e de acordo com o local onde ocorre a colonização das células germinativas, diferenciara em testículo ou um ovário, respectivamente. Nos mamíferos, a primeira manifestação estrutural de diferenciação sexual é detectada na gônada dos machos, onde as células germinativas estão localizadas na medula. A diferenciação do testículo inicia-se quando os cordões sexuais se separam do epitélio celômico como consequência dos arranjos produzidos por uma invasão do mesênquima e vasos sanguíneos que provoca a compactação dos cordões, agora denominados cordões testiculares. As células que rodeiam os cordões se achatam e formam as células mioides, que são responsáveis pela formação das membranas basais. As células do epitélio interno, ou seja, as células de Sertoli, têm duas funções principais: o suporte das CGP e a síntese da hormona antimulleriana, responsável pela regressão dos ductos de Müller e secretada durante o período de diferenciação sexual. As células do estroma que rodeiam os cordões testiculares diferenciam-se para formar vários tipos de células: células mioides, fibroblastos, endotélio e células de Leydig, que são as mais importantes pela sua atividade endócrina. Posteriormente, os cordões testiculares dão origem aos túbulos seminíferos, que contêm o epitélio que produzirá os espermatozoides ao chegar à puberdade. Na fêmea, durante os estágios iniciais de diferenciação gonodal, não se observam mudanças em relação à gônada indiferenciada, só pode-se observar um certo crescimento devido à proliferação de células somáticas e germinativas. As células germinativas iniciam um período de proliferação, que termina com o início da meiose. Iniciada a meiose, dá-se o processo de foliculogênese; neste momento os cordões epiteliais se fragmentam, de tal maneira que cada ovócito fica rodeado de células epiteliais cobertas por uma folha basal fina (figura 1). Para que a gônada primitiva se desenvolva em testículo é indispensável a presença do cromossoma Y, independentemente do número de cromossomas X que contenha o genoma de um indivíduo. O gene determinante do testículo encontra-se localizado no cromossoma Y, denominado sry em ratos e SRY em humanos. O gene sry se expressa durante o desenvolvimento embrionário na crista genital de embriões de camundongos. A expressão é detectável no dia 10,5, pouco depois do aparecimento das cristas genitais, atinge o seu máximo durante o dia 11,5 e mantém-se até pouco depois de ocorrerem os primeiros sinais morfológicos de diferenciação testicular no dia 12,5. Este padrão de expressão é compatível com a teoria de que sry atua induzindo a ativação dos genes (figura 2) que conduzem ao desenvolvimento testicular, sem que exista a necessidade da expressão contínua de sry para manter a diferenciação do testículo após o dia 12,5. Como mencionado anteriormente, a gônada primitiva é composta por vários tipos de células. No entanto, as células germinativas primordiais não são o local de expressão do sry, já que os embriões que necessitam de células germinativas mantêm a expressão de sry e desenvolvem o sexo gonodal normalmente. As células somáticas na gônada em desenvolvimento incluem também as células de suporte. Sabe-se que é nestas células que o sry é expresso para que se diferenciem em células de Sertoli, e a expressão transitória de sry indica que deve ativar a outros genes para a manutenção das células de Sertoli. Uma vez diferenciadas as células de Sertoli, elas se encarregarão da diferenciação do resto das células na gônada. -/- Figura 1: Representação da diferenciação dos órgãos genitais internos. Adaptado de BRONSON, 1989. Figura 2: Cascada de genes envolvidos na diferenciação sexual, adaptado de KOOPMAN, 1999. O fator sry é necessário para a diferenciação do testículo. Embora não se conheçam os genes que provavelmente regulam esse gene, estudos realizados em camundongos demonstram que este gene parece coordenar-se com certos genes autossômicos. Entre estes genes autossômicos, o sox9, que é produzido pelas células de Sertoli uma vez que são estimuladas por sry, de modo que sox9 é um dos genes relacionados estruturalmente com sry. O Sox9 funciona como um fator de transcrição, mas não se sabe se a proteína tem qualquer outra função estrutural; este gene exprime-se abundantemente nos condrócitos e está relacionado com defeitos do aparelho ósseo chamados displasia campomélica. Curiosamente, os pacientes XY com esta condição sofrem frequentemente de reversão do sexo. O Sox9 é um dos poucos genes, além do SRY, do qual as mutações demonstraram interferir com a determinação sexual masculina. No entanto, apenas 75% dos pacientes com anomalias esqueléticas de tipo displasia campomélica têm reversão sexual e não foram encontrados casos de reversão sexual devido a um defeito de Sox9 que não seja acompanhado de defeitos esqueléticos. Isso indica que o Sox9 é apenas um membro da rede de genes que são ativados para determinar a diferenciação sexual, enquanto a rota que rege a condrogênese é mais sensível a perturbações deste. O momento em que se detecta a expressão do gene Sox9 (11dpc em ratos) coincide com a máxima expressão de sry, o que poderia indicar a possibilidade de que sry regule positivamente a Sox9. De fato, na região do promotor de Sox9 há um local de união ao que potencialmente se pode unir o sry. A expressão de Sox9 durante a diferenciação sexual sugere um papel abaixo de sry na diferenciação das células de Sertoli. O cromossoma X também é importante na diferenciação gonodal. O gene DAX-I foi isolado do lócus DSS (Dosage sensitive sex reversal) do cromossoma X. DAX-I é parte da cascata de determinação sexual, mas não é necessário para a formação do testículo. DAX-I é um membro dos receptores nucleares conhecidos como receptores órfãos. Este gene demonstrou ser um poderoso repressor da transcrição de SFI e de vários genes. Os padrões de expressão de DAX-I são complementares daqueles de SFI, ambos expressos nas cristas genitais. Em resumo, dada a evidência exposta, desenvolveu-se a hipótese de que DAX-I é um antagonista de sry; esse antagonismo é dependente dos níveis relativos de DAX-I e sry e de um limiar que varia de espécie para espécie. A DAX-I foi classificada como o gene antitestículo. Na fêmea (cariótipo XX) é importante que ocorra a inativação de um dos cromossomas sexuais X para que se mantenha o equilíbrio genético ao igualar o conteúdo de DNA dos cromossomas. Esse cromossoma inativado constitui o chamado corpúsculo de Barr. No entanto, para que a meiose se realize, é necessário dos dois cromossomas X ativos nos ovócitos para assegurar a diferenciação ovárica e a fertilidade. 1.5 DIFERENCIAÇÃO DOS DUCTOS SEXUAIS O embrião possui, além das gônadas indiferenciadas, dois sistemas de ductos: os de potencialidade masculina denominam-se ductos de Wolff ou mesonéfricos, e os de potencialidade feminina se chamam ductos de Müller ou paramesonéfricos (figura 1). Se a diferenciação gonodal levou à formação de um testículo, a partir do ducto mesonéfrico ou de Wolff se desenvolverão os ductos eferentes, o epidídimo, os ductos deferentes e as vesículas seminais. As hormonas importantes no desenvolvimento do aparelho genital masculino são a testosterona, produzida pelas células de Leydig, e sua forma 5α reduzida, a 5α di-hidrotestosterona. Acredita-se que a testosterona é responsável pela virilização dos ductos de Wolff, e a di-hidrotestosterona dos órgãos genitais externos. No macho, os canais de Müller atrofiam-se devido à ação de uma hormona fetal de origem testicular denominada hormona inibidora das estruturas de Müller (HIM) ou hormona antimulleriana. Este processo começa assim que os cordões espermáticos se formam e se diferenciam as células de Sertoli. A existência de HIM foi proposta baseada em estudos realizados em bezerras freemartin, devido à existência de uma hormona responsável pela atresia dos ductos de Müller que na fêmea dá origem ao útero e aos ovidutos. Essa hormona provoca a involução do aparelho genital do bovino nas gestações gemelares nas quais os produtos de diferente sexo têm comunicação sanguínea por ter ocorrido a anastomose dos vasos de ambas as placentas (figura 3). A HIM é uma glicoproteína pertencente à subfamília de TGFβ, é expressa pelas células que darão origem às células de Sertoli e é um dos primeiros marcadores de diferenciação nestas células. A HIM é secretada na vida adulta pelas células de Sertoli no testículo e por células da granulosa no ovário. No rato a HIM é expressa-se no 12° dia em um teste padrão que segue muito de perto o aumento na expressão de sry. No macho, esta secreção de HIM continua durante a vida fetal e adulta, contudo os níveis de HIM declinam na puberdade devido a um aumento na secreção de testosterona. Vários fatores intervêm na regulação do gene de HIM, incluindo os acima descritos SFI e Sox9. O gene HIM contém segmentos de DNA que são conservados em várias espécies de vertebrados. Existe um nexo de ligação para SFI, que ativa a transcrição de HIM. A mutação no local de ligação de SFI resulta em reversão do sexo em indivíduos XY incluindo genitais femininos normais, presença de um útero formado enfatizando a importância de SFI na determinação sexual e na expressão de HIM. Embora SFI seja um bom candidato como regulador de HIM, é expresso em outras células, como as de Leydig e adrenais, que não expressam HIM. Em contrapartida, Sox9 é expresso unicamente nas células de Sertoli que são as produtoras de HIM. O gene HIM também tem um nexo de ligação para Sox9. Além disso, Sox9 pode atuar sinergicamente com SFI para promover a secreção de HIM. Ao contrário destes dois fatores de transcrição, DAX-I antagoniza a ação de Sox9 e provavelmente SFI sobre o promotor de HIM. Assim, para que as células de Sertoli secretem HIM, a transcrição de DAX-I deve diminuir. Figura 3: Representação da diferenciação dos órgãos genitais externos. Adaptado de BRONSON, 1989. Os ductos de Wolff tornam-se o sistema de ejaculação do macho. A porção mais próxima dos testículos dá origem ao epidídimo, a parte central ao ducto deferente e a porção mais distal às vesículas seminais. A próstata e a parte membranosa da uretra do macho desenvolvem-se a partir da porção pélvica do seio urogenital. A virilização e diferenciação dos ductos de Wolff dependem da produção de testosterona pelo testículo. Quanto aos órgãos genitais externos do macho, o tubérculo genital é ampliado e as dobras uretrais se fundem para formar a uretra peniana. A fusão das dobras uretrais aproxima os tubérculos genitais para formar o escroto (figura 4). Figura 4: Diferenciação do aparelho genital da fêmea e do macho. Adaptado de KOOPMAN, 1989. A diferenciação dos órgãos genitais da fêmea ocorre de forma passiva, já que a ausência de testículos e por isso da hormona inibidora dos ductos de Müller (HIM), assim como dos andrógenos virilizantes, favorece o desenvolvimento dos ductos de Müller, enquanto os de Wolff sofrem atrofia. A porção cefálica dos ductos de Müller dá origem aos ovidutos, que na sua terminação caudal se fundem com o útero. O contato dos ductos de Müller com o seio urogenital induz uma intensa proliferação celular que resulta na formação da área uterovaginal localizado entre o seio urogenital e os ductos de Müller. As células do prato uterovaginal proliferam e aumentam a distância entre as duas estruturas criando o espaço que formará a vagina quando o prato é canalizado e forma um lúmen. Em contraste com o que ocorre no macho, na fêmea a maior parte do seio urogenital se mantém exposta na superfície da abertura onde desembocam a vagina e a uretra. O tubérculo urogenital da fêmea tem um crescimento limitado e forma o clitóris. A sequência de passos da diferenciação sexual do aparelho genital é resumida na tabela 1. Tabela 1: Destino em desenvolvimento dos rudimentos sexuais dos fetos macho e fêmea dos mamíferos -/- Rudimento sexual Macho Fêmea Gônada Testículo Ovário Ductos de Müller (Paramesonéfricos) Vestígios Útero, parte da vagina, ovidutos Ductos de Wolff (Mesonéfricos) Ductos eferentes deferentes, epidídimo, vesículas seminais Vestígios Seio urogenital Uretra, próstata, glândulas bulbouretrais Parte da vagina, uretra, vestíbulo, glândulas vestibulares Tubérculo genital Pênis Clitóris Pregas vestibulares Escroto Lábios vulvares Fonte: HAFEZ, 2004. 1.6 DIFERENCIAÇÃO SEXUAL DO HIPOTÁLAMO Os processos de diferenciação sexual não se limitam apenas às células somáticas do organismo do feto, mas incluem também os centros nervosos superiores do cérebro. Assim, da mesma maneira que a gônada e os ductos sexuais se desenvolvem para o tipo feminino ou masculino, propôs-se que o cérebro pode ser "masculinizado" ou permanecer "Feminizado". A diferenciação do hipotálamo vai depender do ambiente esteroidal do neonato e ocorre na fase perinatal. Estes eventos serão de grande transcendência na vida reprodutiva do indivíduo. Tanto a fêmea como o macho nascem com a capacidade de secreção de gonadotropinas de acordo com um padrão cíclico; contudo, no macho, a exposição do hipotálamo à ação dos andrógenos testiculares durante os primeiros dias da vida extrauterina provoca a masculinização, com o qual o hipotálamo do macho é programado para que a secreção de gonadotropinas se realize a um ritmo relativamente constante por parte da hipófise (secreção tônica). Na fêmea, tanto a secreção tônica como a cíclica se conservam. No entanto, observou-se que a injeção de testosterona ou o transplante de testículo na rata fêmea durante os primeiros dias de vida, suprime a sua futura atividade estral (secreção cíclica). Por outro lado, se os ovários forem transplantados para o rato macho normal castrado na idade adulta, o animal não desenvolve qualquer atividade cíclica, mas se os machos transplantados forem castrados ao nascer, o ovário é capaz de efetuar mudanças cíclicas e ovulações. Isto foi demonstrado em roedores, mas não em animais domésticos ou na espécie humana. Portanto, o padrão de secreção de gonadotropinas, seja cíclico ou tônico, não depende da hipófise, mas do hipotálamo e sua correta diferenciação. 1.7 CONCLUSÕES A maioria dos conhecimentos no campo da biologia do desenvolvimento e, muito especificamente, dos processos de diferenciação sexual têm sido originados de estudos relacionados com desordens congênitas, que na sua maioria devem-se a defeitos de genes específicos. A análise detalhada destas desordens permitiu entender alguns mecanismos endócrinos, moleculares e genéticos envolvidos na diferenciação sexual. A identificação do gene sry como determinante do testículo foi uma contribuição crucial e abriu as portas à compreensão dos mecanismos moleculares e celulares relacionados com o desenvolvimento do testículo. Se este gene não estiver presente, é criado um programa genético alternativo para levar a cabo a diferenciação gonodal para o ovário. Finalmente, devemos ter presente que é necessária uma correlação entre mudanças morfológicas e expressão de genes durante o desenvolvimento para entender os mecanismos relacionados com a diferenciação. -/- Apoio -/- Realização -/- REFERÊNCIAS BIBLIOGRÁFICAS ANDERSON, Robert et al.

„O pełnej znajomości prawa można mówić tylko wówczas, gdy zna się prawo i wytworzone przez praktykę reguły posługiwania się nim” – pisał swego czasu Marek Zirk-Sadowski. Pogląd ten wiąże się z niezwykle istotnym sporem o kryterium poprawności dokonywanej przez sędziów wykładni prawa. Zlokalizowanie takiego kryterium wydaje się być szczególnie ważne choćby ze względu na zawartą w naszym systemie prawnym konieczność realizowania zasady trójpodziału władzy, zgodnie z którą w procesie stosowania prawa nie może dochodzić do tzw. kryptoprawotwórstwa. Celem niniejszego tekstu jest (...) zaprezentowanie wybranych koncepcji poprawności wykładni prawa oraz ich krytyka w świetle neopragmatyzmu Stanley'a Fisha, filozofa prawa oraz profesora literaturoznawstwa, którego głównym przedmiotem refleksji był problem interpretacji. Filozofia amerykańskiego neopragmatysty opiera się na dwóch koncepcjach: reader-response criticism i wspólnotach interpretacyjnych. Reader-response criticism polega na skupieniu się na afektywnym aspekcie procesu interpretacji, uznając czytelnika za kluczową instancję tego procesu; koncepcja wspólnot interpretacyjnych z kolei ma wytłumaczyć, dlaczego podmiot interpretuje w taki a nie inny sposób. Zaproponowana przez Fisha metoda pozwala uznać, że de facto jedynym możliwym kryterium poprawności wykładni są inne decyzje sędziowskie. W świetle powyższych uwag wydaje się zasadnym stwierdzenie, że podejście Fisha umożliwia pogłębienie refleksji na temat jednej z kluczowych kwestii zarówno dla praktyki jak i teorii prawniczej, tj. poprawności wykładni prawa.

W. Matthews Grant has argued that it is possible to reconcile a strong theory of God’s causal sovereignty with libertarian freedom by denying that God causes the acts of free creatures by means of some factor intrinsic to Himself. Grant argues that the accounts on which God causes those actions of His creatures in virtue of His decrees cannot be libertarian. I will argue that two classical theories of grace, despite holding that God causes creaturely acts in virtue of a (...) divine decree or intention, remain libertarian in just the same sense Grant’s account is. I controversially propose that this is true even of Banezian theories of grace, on which God causes free actions directly. Instead, I suggest that we can characterize what it is for a theory to be theological determinist according to a distinction proposed by Eleonore Stump. (shrink)

The English Synopsis is after the text of the book. The book presents an original and generalizing substantive vision of the philosophy of science through the prism of a detailed analysis of the polysystem structure of scientific theories. Theories are considered, firstly, as complex specialized forms of developed scientific thinking about the realities studied by natural science, secondly, as constantly improving tools for producing new knowledge in interaction with experimental research, and thirdly, as carriers of ordered and verified knowledge. Emphasis (...) is placed on their nominal and ontic subsystems. The book develops personal and joint research of the authors (theoretical physicist and philosopher), the experience of teaching philosophy of physics at NaUKMA, philosophy of science at the Higher School of Philosophy at the H. Skovoroda Institute of Philosophy of the National Academy of Sciences of Ukraine and theoretical physics at the National Technical University "Ihor Sikorsky Kyiv Polytechnic Institute". The research is based on a significant source base covering works of modern Western researchers in natural science and philosophy of science. For students, teachers, and scientists who are interested in the problems of modern philosophy of science and have a certain amount of scientific knowledge. It will also be useful for high school students who are eager to become scientists. (shrink)

Wat betreft economische groei en ontwikkeling van de werkloosheid heeft de Nederlandse economie het sinds 1973 slechter gedaan dan andere OECD-landen. Op de vraag naar de oorzaken van die slechte prestatie zijn in het verleden uiteenlopende antwoorden gegeven door o.m. Bomhoff en Clavaux. Ook zijn er diverse wegen aangegeven om op te rukken naar een betere positie. In dit artikel presenteren de auteurs de resultaten van een internationale doorsnee-analyse om de verschillen in economisch succes tussen landen met behulp van een (...) eenvoudig neo-klassiek macro-economisch model te verklaren. Dit biedt de mogelijkheid om te traceren wat de rol van de exportgroei, de groei van de bevolking, de wisselkoers, de verhouding tussen de binnenlandse en de buitenlandse prijsontwikkeling en de investeringsquote voor verschillen in economische ontwikkeling is geweest. Vooral de uitvoer gecorrigeerd voor de omvang van de bevolking, de investeringsquote en de nominale wisselkoers komen als belangrijke verklarende variabelen naar voren. Op grond van hun analyse komen de auteurs tot de conclusie dat een beleid gericht op het verbeteren van de Nederlandse economische prestatie op lange termijn zich vooral zou moeten concentreren op het benutten van exportkansen en op een hoog investeringsniveau ter bevordering van technologische vernieuwing en daarmee verbetering van de concurrentiepositie. Daarbij moet worden voorkomen dat revaluatie van de gulden het exporteffect teniet doet. (shrink)

Apresentaremos neste texto a tese de David Hume sobre a identidade pessoal tal como é apresentada no Tratado da natureza humana, de sua autoria. No apêndice da obra, Hume apresenta dúvidas sobre a tese que defendeu, apontando uma série de problemas que não se resolvem em sua teoria. Mas o tratamento desses problemas e uma possível resposta a Hume podem ser encontrados em D. W. Winnicott.

W wiktoriańskiej Brytanii współistniały dwa kontrastujące ze sobą wizerunki o kobiet – anioł w domu i upadły anioł. Odzwierciedlały one podwójne standardy moralne epoki. Wyobrażenia te oparte były na moralności potocznej i stylach myślenia epoki, czyli dyskursach obecnych w wiktoriańskiej nauce, medycynie, literaturze oraz sztuce. Artykuł omawia zarówno przekazy zawarte z źródłach moralności potocznej, jak i wymienione dyskursy, które prowadziły do nadawania społecznych ocen o (nie)normalności. Przedstawionym wskaźnikiem takich ocen społecznych są przykładowe sankcje i postawy społeczne wobec stylów życia i (...) ról społecznych, jakie odgrywały kobiety wiktoriańskie. (shrink)

Myśl fryburskiego filozofa religii, Bernharda Weltego, wielokrotnie dotykała zagadnienia nicości. Artykuł prezentuje funkcje, jaką Welte przypisał idei nicości w kontekście doświadczenia konstytutywnego, wyznaczającego podstawową charakterystykę ludzkiej egzystencji. Doświadczenie konstytutywne pociąga za sobą przenikanie się czyjejś skończoności z nieskończonością. Ta pierwsza wyraża się w byciu świadomym własnej śmiertelności i winy, ta druga w aktywności ludzkiego ducha, szczególnie w odczuwaniu obowiązku. Bycie człowieka sytuuje się między tymi przeciwstawnymi siłami, poszukuje sensu swojej egzystencji. Jednocześnie stwarza ono różne relacje, jakie mogą między nimi zachodzić. (...) Ich porządek może prowadzić do afirmacji bądź negacji czyjejś egzystencji. Jeżeli dodamy do owych relacji doświadczenie nicości (wraz z jej specyfiką), to tworzą one razem akt wyboru między afirmacją a negacja bardziej przypominający ostateczny wybór między nadzieją a rozpaczą.

Autorka rozważa relacje między wartościami, szczególnie moralnymi, a dziełem muzycznym. Przedstawiając najpierw rozumienie wartości w filozofii Romana Ingardena, a następnie przywołując przykładowe sformułowania moralizmu w odniesieniu do muzyki (autorstwa Rogera Scrutona, Platona i Petera Kivy’ego), autorka pyta, czy możemy uważać dzieło muzyczne za nośnik wartości moralnych. Następnie badając, w jaki inny sposób dzieło muzyczne może być związane z wartościami moralnymi, autorka dochodzi do wniosku, że relacje między wartościami moralnymi a dziełem muzycznym należą do stosunków subtelnych i być może tym, co (...) zawdzięczamy dziełom muzycznym jest umiejętność słuchania.

In the field of phenomenology philosophers more and more frequently show interest in early Christian thought – including apophatic theology – which, in result, affects the understanding of the role and significance of art. „Invisibility” in art and the manifestation of God through the work of art is a mystery which cannot be satisfactorily explained by traditional philosophical aesthetic models. Negative theology, together with its key apophatic way brings a new perspective of understanding art into contemporary aesthetic debates. Its 'reductive' (...) application can be found especially in the theory of the icon. Paweł Florenski's icon analysis and Jean-Luc Marion's category of the ‘saturated phenomenon’ converge in many points. Henry Dume ry’s henological reduction which is complementary to, but at the same time exceeds Edmunda Husserl's reductions, extends the horizon of the 'invisible' dimension of art by the relation the Spirit (intelligibility) makes with Transcendence. In the article I will show the cohesion of contemporary phenomenological thought, early Christian apophatics and the theory of the icon. I will also consider whether an aesthetic and theological framework so structured could be valid and useful as a general philosophical theory of art. (shrink)

W. V. O. Quine is the prominent advocate of naturalized epistemology, a collection of philosophical views that employ scientific methods, results, and practices to solve epistemological problems. In this paper, I explore whether Quine’s argument to replace epistemology by science is convincing. In naturalized epistemology, Quine totally rejects the normative aspect of epistemology; he focuses on the descriptive part of epistemology. Other thinkers such as Kim, Stroud, Almedir, Rorty argues that epistemology without norm is epistemology in name only. Furthermore, all (...) philosophical questions cannot be answered by applying scientific methods, because philosophy’s scope is broader than science. Thus, Quine’s attempt to scientized philosophy in general and epistemology, in particular, is unattainable. (shrink)

This article proposes to present, in general, the thought of the German philosopher G. W. F. Hegel about history. Using mainly the work Philosophy of History, I seek first to analyze and to explain the different modes of historical approaches elaborated by Hegel, which are: the original history, the reflective history and its subdivisions and, finally, the philosophical history. After that, I center my studies on the concept of progress or, more precisely, historical progress. According to Hegel, philosophical history appears (...) when we perceive that rationality governs the world, and therefore the actions and events that have occurred, occur and will occur are part of this rationality. Such a perception – that is, understanding that history develops and progresses according to rationality – is possible when we turn to the study of history, using it as material, and carefully observing and analyzing past historical events. According to Hegel, this historical process is the course of the spirit, constantly seeking a greater awareness of freedom and, therefore, a greater understanding of itself, because freedom is already in it, and it is not something alien, distant or external, it is in its center and is its substance. According to Hegel, nature, despite its polymorphic transformations, is only a repetitive and monotonous cycle, where there is nothing new under the sun. However, in the process of development of the spirit, that is, the spirit knowing itself, the new appears, this is progress, which, in turn, is aimed at the realization of freedom, with a view to its concretization in the State.

Przemocy jest coraz mniej – zarówno w czasie pokoju, jak i podczas wojen. Na przykładzie trzech konfliktów zbrojnych z ostatnich lat zastanawiam się, czy decydenci powinni prowadzić działania zbrojne w taki sposób, by zminimalizować całkowitą liczbę ofiar.

Roman Ingarden has exerted an immense influence on the development of aesthetics, and his texts in this field continue to inspire in-depth studies on art, despite the passage of several decades since the publication of his major works.

(...) In this article, I address the question of the continued relevance of Roman Ingarden’s approach to the musical work within the context of current phenomenological research, in particular that which concerns the subject of aesthetic concretisation.

A Few Notes on Aspect Seein g in Contemporar y Aesthetics In this paper author examines the problem of aspect seeing in reference to works of Ludwig Wittgenstein and Virgil C. Aldrich posing the question of whether they are applicable to experience of musical works. Drawing on examples from Wittgenstein’s Philosophical Investigations, author maintains that hearing a melody as solemn, sad, et cetera is neither universal nor unequivocal. Musical work, author suggests, does not present itself spontaneously to the listener. Conversely (...) it must be sought and found. To speak of aspect hearing or hearing as (as aesthetic hearing) in reference to music, one must seek out those qualities of musical work that are perceptual but also individually grasped in contrast to what is given in experience through acculturation and training.

Krzysztof Trzciński, ‘Some Remarks on the Idea of Rotational Presidency in an African State.’ The article has been published in “Afryka” 31-32, 2010, pp. 29-44. The main aim of this article is to explain and analyze in a critical way the concept of the rotational presidency, proposed for a multiethnic African state by a Ghanaian philosopher Kwame Gyekye. In his opinion, the presidency in an African state should be rotated between all ethnic groups. According to Gyekye, this system would allow (...) the sharing of power between ethnic groups, create trust in their relations and, as a consequence, improve the coherence of a multiethnic state. However, Gyekye’s concept lacks some essential details and seems very difficult to be implemented. Wielu afrykańskich badaczy polityki i innych intelektualistów niezadowolonych z realiów sprawowania, czy wręcz zawłaszczania władzy przez rządzących we współczesnym afrykańskim państwie, szuka rozwiązań ustrojowych alternatywnych wobec obecnie istniejących. Pragną oni ustanowienia w afrykańskim państwie porządku demokratycznego, ale skrojonego na potrzeby jego wieloetnicznej specyfiki. Jedną z wysuwanych propozycji jest osłabienie pozycji prezydenta, który w Afryce zwykle wywodzi się z najliczniejszej lub najsilniejszej grupy etnicznej i posiada bardzo ważne oraz rozbudowane prerogatywy. Sposobem umniejszenia roli urzędu prezydenckiego może być rotacja przywództwa, która stosowana jest w niektórych porządkach ustrojowych (zwłaszcza w Szwajcarii, Bośni i Hercegowinie, na Komorach), a jej współczesnych korzeni należy szukać w ustroju dyrektoriatu z czasów Rewolucji Francuskiej.

I argue that Ireneusz Ziemiński doesn't justify his skepticism about knowledge of existence of God. First, he reduces a question to metaphysical one - do we have sound, valid proofs of God's existence and imposes too heavy conditions on arguments for God. Second, he doesn't show that disagreement between philosophers in that question justify his negative assessment of arguments. Third, Ziemiński omits epistemological question what is knowledge of God's existence, especially in its direct form as well as externalistic account's of (...) knowledge of God, for example Plantinga's and Alston's.

Title in English: "Omnipartiality. On deliberation in governance for health with the inclusion of emotions, self-interests and expertise" Abstract: To what extent it is possible to reconcile the will of the people with expertise? That is the traditional question of democratic policymaking. However, the dilemma outlined in this way is very misleading. It suggests that citizens have no knowledge to offer on any given issue. In addition, it insinuates some peculiar resistance of the expert elite to ignorance, egoism or emotions. (...) A more appropriate question would rather be the following: To what extent policymaking based on expertise is possible at all? Yet another question follows. Is policymaking based solely on evidence even sound? Is the traditional ideal of impartiality, an exclusion of egoism and passions from policymaking a good ideal? Author of the book argues that a good governance for health – and policymaking in general – requires the inclusion and proper balance of the three key inputs of governance: expertise, self-interest and emotions. Considering them requires going beyond typical public debates, bargaining and even beyond expert panels. It requires public deliberation in which the three inputs could engaged in a form of constructive dialogue with each other. In good governance, we should not limit ourselves to evidence insulated from material interests and strong intuitions. We cannot orient ourselves on procedural, neutral impartiality. Rather, we should move towards omnipartiality. (shrink)

W artykule tym przedstawiam koncepcję rozwoju autorstwa wybitnego nigeryjskiego myśliciela i demokraty Claude’a Akego. Ake zaproponował abstrakcyjny paradygmat rozwoju społeczeństw afrykańskich w warunkach demokracji. Paradygmat ten opiera się na rolnej strategii rozwoju, zgodnie z którą powinien być on uzyskiwany małymi krokami i pierwotnie generowany na wsi. Ake zdefiniował rozwój jako proces, „poprzez który ludzie kształtują i zmieniają siebie oraz swoją sytuację życiową, by osiągać wyższe poziomy cywilizacyjne, zgodnie z własnymi wyborami i wartościami”. Zdaniem nigeryjskiego myśliciela, rozwój jako proces zbiorowy powinien (...) być wytwarzany przez tych, którzy mają go doświadczać. Ake krytykował dominujący, jego zdaniem, zachodni paradygmat rozwoju Afryki, zgodnie z którym rozwój może zostać narzucony Afrykanom z zewnątrz, a demokratyczna władza wcale nie musi stanowić warunku sine qua non rozwoju. W opinii Akego, zachodnie próby zintensyfikowania rozwoju w Afryce, które cechował brak zrozumienia dla afrykańskich uwarunkowań kulturowych, w tym sposobów myślenia i życia Afrykanów, skończyły się porażką. Koncepcja Akego, choć ciekawa i poparta ważnymi argumentami oraz przykładami, nie jest wolna od uogólnień i sprzeczności. Co więcej, jak się wydaje, nigeryjski myśliciel zaprezentował model rozwoju bliski autarkii i wyzuty z realiów współczesnej ekonomii. W konsekwencji krytycznie oceniam część opinii Akego i ukazuję podstawowe, moim zdaniem, ich mankamenty. (shrink)
