The objective is to perform a comparative evaluation of the pancreatic hydrolysates prepared from fish and squid to determine the optimal culture medium for Listeria monocytogenes.Materials and methods. The following raw materials were used in the study: Pacific Herring (Clupea pallasii), Alaska Pollock (Gadus chalcogrammus), Common Roach (Rutilus rutilus lacustris), European Squid (Loligo vulgaris). The raw materials were subjected to enzymatic hydrolysis using the pancreas (according to Hottinger). A study of the physicochemical properties of pancreatic hydrolysates (content of free amino nitrogen (FAN), acidity of fish hydrolysates, the amino acid composition) was carried out.. The specific activity of nutrient media during the cultivation of the test strain L. monocytogenes 766 was assessed by a complex of microbiological methods.Results and discussion. The highest content of FAN at the end of enzymatic hydrolysis was observed in the pancreatic hydrolysate of the common roach (6%), the acidity of the hydrolysate remained stable from 6th to 13th day of the hydrolysis process (pH 7.2). Pancreatic hydrolysate of the common roach contained a number of amino acids that are most essential for the growth of Listeria. An assessment of the biological properties of nutrient media prepared on the basis of the obtained hydrolysates demonstrated that the best results in terms of sensitivity and germination of L. monocytogenes 766 showed a nutrient medium based on the pancreatic hydrolysate of the common roach. During the cultivation of L. monocytogenes 766 the test strain retained its morphological and cultural properties and did not show signs of dissociation.Conclusion. The research results have shown that the pancreatic hydrolysate of the common roach is a promising protein basis for the construction of an experimental environment for listeria.

Statistical studies of patients' sensitization to allergens make it possible to form a general picture of sensitization for the whole country, help doctors to develop competent tactics for examining patients in the regions and can be used for the development of new formulations of allergy vaccines.Objective. To study the sensitization to inhalation allergens Dermatophagoides pteronyssinus (Der. p.) and Dermatophagoides farinaе (Der. f.) in Moscow and the Moscow region in 2010–2019 and to identify the structure, features and dynamic changes in sensitization to Der. p. and Der. f. based on the analysis of the allergosensitivity profile of patients with IgE-mediated allergic diseases (IgEA).Materials and methods. Blood serum samples of Moscow and the Moscow region residents with IgEA (n = 2849) were examined by RIDA AllergyScreen method in 2010–2019.Results. According to the results of the study spanning the last ten years, about 18–21% of patients with IgEA in Moscow and the Moscow region have sensitization to Der. p. and/or Der. f. There was a statistically significant decrease in sensitization to Der. p. from 2017 to 2019. House dust mites of the type Der. f. more often cause a higher level of sensitization compared to Der. p.Discussion. The data obtained indicate the change in the sensitization of patients to Pyroglyphidae, namely Der. p. against the background of changes in the housing acarocomplex of Moscow and the Moscow region. Features of protein molecules of these species of dust mites may contribute to their varying degrees of the impact on immunological reactivity in the population studied.Conclusions. The decrease in the prevalence of Der. p. is most likely accounted for the changes in the ecosystem of homes of residents of Moscow and the Moscow region.

Published: March 2021

Purpose of the study. To establish risk factors for tuberculosis (TB) in children perinatally exposed to HIV and HIV-infected for the development of corrective measures.Materials and methods. Outpatient records (form No. 025/y) of 216 children perinatally exposed to HIV and 121 children with HIV infection and their parents (281 individuals) were analyzed. The control group consisted of 100 healthy children. Epidemiological (descriptive, evaluative and analytical) and statistical research methods were used in the study.Results. The likelihood of contact with a patient with an active form of TB was significantly higher in perinatally exposed to HIV and HIV-infected children compared to children in the control group (p 0.001). The risk of TB in HIV-exposed children was 5.3 times higher in foci where both parents were HIV-infected than in foci formed by discordant couples (RR = 5.3; 95% CI 1.7–21.7). Children in study groups who were not vaccinated with BCG had the highest risk of TB compared to children in the control group (RR = 1.9; 95% CI 1.6–2.2).Conclusion. Risk factors for TB in children perinatally exposed to HIV are untimely vaccination against TB or its absence and living in the foci where both parents are HIV-infected. The predictors of the development of TB in HIV-infected children are household contacts with TB patient , late diagnosis of HIV infection, and late prescription of highly active antiretroviral therapy after the formation of severe immunosuppression.

DESAIN PENGUATAN KUALITAS POLITIK DINASTI DALAM PEMILIHAN KEPALA DAERAH
Authors: Siboy Ahmad
Published: March 2021

The purpose of this reseach is to describe the factors and implications of the proliferation of political dynasties and to find designs to create dynastic politics that do not conflict with the spirit of local democracy in Indonesia. The problem of this research is the factors and implications that make politics flourish in simultaneous Pilkada and the ideal dynastic political design. The research method used is normative juridical through the concept of an approach, legislation, case approach and historical approach. The results showed that dynastic politics mushroomed because the regional head as the ruler was unable to run again, the ruler at the national level wanted to use his power to place family members as rulers at the regional level. As a result, many candidates for regional heads are nominated without the competence and willingness to become regional heads. The ideal dynastic political design can be achieved with the requirements to be declared valid as a candidate for regional head as well as regulations that prevent unqualified regional head candidates from fulfilling formal or legal requirements as regional head candidates.

The Role of Celebrity and Status in the Performance–Pay Relationship: Evidence from the ‘Big Five’ European Football Leagues
Authors: Giangreco Antonio , Slavich Barbara , Piazza Alessandro , Castellucci Fabrizio , Mohadjer Cyrus
Published: March 2021

This study explores the reasons behind the existence of frequent mismatches between performance of individuals in organisations and their salary, with a specific focus on contexts where actors or employees are highly visible and representative of organisations. We argue that two intangible assets – celebrity and status – might affect the intensity of the link between individual performance and pay levels. Using a panel data set of professional footballers from the top five European leagues, we find that there is a positive association between players’ performance in one period (season) and their salary in the subsequent season, and that this relationship is negatively moderated by both the players’ celebrity and status. Theoretical contributions and managerial implications are discussed, along with the generalisability of the results to other settings.

A FUNÇÃO SOCIAL E A QUALIDADE DA EDUCAÇÃO: OS IMPACTOS DA PANDEMIA PELA COVID-19 NO SISTEMA EDUCACIONAL BRASILEIRO E A FORMAÇÃO DOCENTE
Authors: Martins Vieira Walderês
Published: March 2021

O estudo da função social da educação e sua importância no processo de formação e/ou construção da personalidade do indivíduo, somente será possível, a partir do entendimento de um contexto social de época, porque, para alguns, o processo educacional poderá ser influenciado pelo desenvolvimento de questões sócio-políticas, no entanto, para outros, a educação tem o poder de determinar as relações sociais, gozando de uma autonomia plena em relação à estrutura social. Também é necessário promover uma reflexão, no que tange a influência da cultura característica de uma determinada época, na formação da personalidade do indivíduo e no processo ensino aprendizado. Inicialmente se desenrolou na história o problema entre a fé versus a razão, pois, nossa sociedade foi, e ainda hoje, se caracteriza pelo pluralismo cultural e religioso, bem como por mudanças rápidas no meio em que vivemos e isto trouxe, em certa época, consequências na seara educacional. Pretendemos no decorrer deste estudo, após analisaras mudanças relativas à consideração da função social da educação/ensino, apresentar alguns aspectos positivos e negativos, que podem impactar no alcance da qualidade da educação, quer com base em períodos anteriores, como também posteriores a decretação do estado de calamidade pública, ocorrido a partir da consideração da pandemia pela COVID-19, em nosso país. Iremos ainda, apresentar o resultado de uma pesquisa aplicada aos Professores da Rede Pública Estadual de Ensino da Região  metropolitana de Sorocaba, que teve como objetivo auferir a conscientização da importância de seus papéis no processo educacional e a formação docente, bem como auferir elementos relativos ao quantitativo de adesão dos docentes, em relação a utilização de novas metodologias e ferramentas/recursos tecnológicos na educação.

We conclude that Amphotericin B and alcoholic extract of Trametes spp. have activity in treating the histological lesions that resulted from A. fumigatus infection.
Multidimensional Boltzmann Neutrino Transport Code in Full General Relativity for Core-collapse Simulations
Authors: Akaho Ryuichiro , Harada Akira , Nagakura Hiroki , Sumiyoshi Kohsuke , Iwakami Wakana , Okawa Hirotada , Furusawa Shun , Matsufuru Hideo , Yamada Shoichi
Published: March 2021

We develop a neutrino transfer code for core-collapse simulations that directly solves the multidimensional Boltzmann equations in full general relativity. We employ the discrete ordinate method, which discretizes the 6D phase space. The code is an extension of our special relativistic code coupled to a Newtonian hydrodynamics code, which is currently employed for core-collapse supernova simulations. In order to demonstrate our code’s capability to treat general relativistic effects, we conduct some tests. We first compute the free streaming of neutrinos in the Schwarzschild and Kerr spacetimes and compare the results with the geodesic curves; in the Schwarzschild case, we deploy not only a 1D grid in space under spherical symmetry but also a 2D spatial mesh under axisymmetry in order to assess the capability of the code to compute the spatial advection of neutrinos. Second, we calculate the neutrino transport in a fixed matter background, which is taken from a core-collapse supernova simulation with our general relativistic but spherically symmetric Boltzmann hydrodynamics code, to obtain a steady neutrino distribution; the results are compared with those given by the latter code.
The Parallax Zero-point of Gaia Early Data Release 3 from LAMOST Primary Red Clump Stars
Authors: Huang Yang , Yuan Haibo , Beers Timothy C. , Zhang Huawei
Published: March 2021

We present an independent examination of the parallax zero-point of the Third Gaia Early Data Release (hereafter EDR3), using the LAMOST primary red clump (PRC) stellar sample. A median parallax offset of around 26 μas, slightly larger than that found by examination of distant quasars, is found for both the five- and six-parameter solutions in EDR3, based on samples of over 63,000 and 2000 PRC stars, respectively. Similar to the previous investigation of Lindegren et al., to which we compare our results, the parallax zero-point exhibits clear dependencies on the G magnitudes, colors, and positions of the objects. Based on our analysis, the zero-point of the revised parallax can be reduced to a few μas, and some significant patterns, e.g., discontinuities with stellar magnitude, can be properly removed. However, relatively large offsets (>10 μas) are still found for the revised parallaxes over different positions on the sky.

Où sont les femmes dans les histoires de la philosophie au Mexique ? Un cas d’injustice épistémique
Authors: del Río Fanny , Rollet Brigitte
Published: March 2021

Selon les dix-huit histoires de la philosophie mexicaine analysées dans cet article, le nombre de philosophes femmes est négligeable par rapport à celui de leurs homologues masculins. S'agit-il d'une donnée objective conforme à la réalité ou la conséquence d’un préjugé de genre ? Je propose d'examiner ces ouvrages à partir du concept d’injustice épistémique (Fricker 2007) avec l'idée d’introduire une nouvelle approche reflétant la participation et l'apport effectifs des femmes à la philosophie, et d'exiger de la communauté académique la création de nouveaux programmes incluant l’étude des œuvres des philosophes mexicaines. Il est important de dénoncer l’injustice épistémique à laquelle notre historiographie traditionnelle a soumis les femmes par une analyse critique-éthique et de proposer les moyens d’y remédier afin de rectifier une vision biaisée et donc déformée de notre histoire de la pensée, qui non seulement appauvrit notre conscience historique mais ne rend pas justice au véritable rôle joué par les femmes dans la philosophie au Mexique.
Les mots et les images de la relation entre l’un et l’autre
Authors: Boni Tanella
Published: March 2021

Comment penser aujourd’hui la place des Africaines dans leurs sociétés dites postcoloniales ? Ce texte propose de situer la complexité de la relation entre l’un et l’autre à la croisée des langues et des cultures. La domination d’une langue – le français – est l’un des critères mobilisés en vue de penser les représentations et les imaginaires liées au corps des femmes. Il s’agit d’aller au-delà de la race, de la classe, du genre et d’autres approches proposées par les perspectives intersectionnelles. Les expériences vécues et les quêtes identitaires qui aliènent ou émancipent les corps et les esprits ne doivent pas être perdues de vue. Si l’émancipation peut s’effectuer individuellement, en luttant contre toutes sortes d’obstacles réels ou imaginaires, il importe de souligner la force de ce qu’on pourrait appeler la « solidarité féminine » et qui reste encore à penser.
Féminismes et « convergence des luttes » au temps de la Covid-19 et de la cancel culture
Authors: Sénac Réjane
Published: March 2021

Le mouvement de réappropriation des espaces physiques et virtuels de parole pour dénoncer les injustices et ceux qui les commettent a pris des formes multiples : de l’occupation de places publiques à la libération de la parole contre les violences systémiques, sexistes et racistes en particulier, via des mouvements comme #MeToo et #OnVeutRespirer. Les féminismes contemporains s’inscrivent ainsi dans un contexte de mobilisation caractérisé par la défiance vis-à-vis d’une démocratie représentative perçue comme confisquée par les élites et par un horizon de « convergence des luttes » ne recomposant pas l’hégémonie d’un critère ou d’une idéologie. Comment, au sein de la société française contemporaine, l’entrecroisement des urgences écologique, sociale et sanitaire questionne-t-il le rapport à l’engagement, en particulier féministe ? Cette interrogation est appréhendée à partir d’une enquête qualitative, menée de juillet 2019 à août 2020, auprès de plus de 120 responsables associatifs féministes, anti-racistes, écologistes, antispécistes, pour la justice sociale et/ou de lutte contre la pauvreté, mais aussi d’activistes avec des affiliations plurielles et fluides. Après avoir abordé la manière dont la question du « faire commun » se pose à l’ère de la Covid-19 et des controverses autour de la « cancel culture », nous examinerons comment les féminismes contemporains sont mis à l’épreuve par l’horizon d’une émancipation partagée dans une interdépendance apaisée.

S’appuyant sur Henri Lefebvre et André Gorz, philosophes et du quotidien et de la vie, Alice Sternberg explore les possibilités de développer, à l’aune du monde vécu et à l’échelle locale, des communs fondés sur le travail pour soi et la coopération .
Les travaux et les jours de la noblesse militaire à travers les archives russes des Langeron
Authors: Piménova Ludmilla
Published: March 2021

Les archives familiales des Langeron furent achetées chez des antiquaires français dans les années 1920 ; elles sont aujourd’hui conservées aux Archives d’État russe pour l’histoire sociale et politique. Parmi les documents du fonds se trouvent des mémoires qui datent de la deuxième moitié du xviii e  siècle ; ils furent composés par deux frères, le marquis et le comte de Maulévrier-Langeron qui occupaient de hauts postes militaires en Bretagne. Le premier élabora des projets de réformes fiscales incluant l’abolition des privilèges ; le deuxième décrivit la ville de Roscoff et sa population en essayant d’en dresser un classement. Les deux frères apparaissent comme des aristocrates se sentant responsables du destin du royaume et disposés à jouer le rôle de conseillers auprès du roi et des ministres.
Des communs à l’en-commun : quelle écopoétique ?
Authors: Astruc Rémi , Baudet Émeline
Published: March 2021

Faire de la littérature un partage, à travers la mise en commun d’un sens qui n’émerge qu’à la faveur de cette discussion critique et solitaire qu’est la lecture, revient à adresser un pied de nez magistral à toutes les entreprises de privatisation qui déchirent et morcellent notre monde. C’est un ultime démenti à tous ceux qui font de l’ensemble des sphères intime et sociale des objets quantifiables, convertibles et échangeables sur des marchés sans cesse plus vastes. Reconnaître à la littérature, comme nous le proposons ici, guidés en cela par la lecture de Leonora Miano, Zakes Mda et Antoine Volodine, ce pouvoir d’être un commun, à travers la Communauté qui s’institue dans le geste même de sa réception, c’est comprendre que la ressource à partir de laquelle cette dernière se dresse est, par essence, inappropriable.
Voix, oralités : vers une échopoétique transculturelle
Authors: Bonvalot Anne-Laure , Brézillon Héloïse , Cazalas Inès , Decaux Sylvie , Lorin Marie , Suchet Myriam
Published: March 2021

La conviction de ce texte collectif est que l’écopoétique est aussi une échopoétique. D’où découlent trois principes. Le premier est que la voix met en écho le vivant, au sens où elle engage toujours des corps-territoires singuliers, comme par exemple chez les babaçueiras des plantations de palmiers au Brésil et les Soubalbés qui chantent le fleuve Sénégal. Le deuxième principe est que la voix circule entre l’écrit et l’oral, impulsant une énergétique dans les performances (celles d’Alain Damasio notamment), les barricades de mots et les slogans proférés sur des territoires en lutte. Enfin, son dernier principe est que la voix engage une écoute, une disponibilité qui prend la forme d’un espace intérieur où se laisser affecter jusqu’à devenir toujours plus autrement soi.
Enjeux éthiques de l’écopoétique. Lectures collectives de Pierre Bergounioux, Édouard Glissant, Nancy Huston, Sony Labou Tansi et Jules Verne
Authors: Chavoz Ninon , Desquilbet Alice , Even Kevin , Laure Charlotte , Vigy Marie
Published: March 2021

Notre article décline différents enjeux éthiques de l’écopoétique de façon située, en les mettant à l’épreuve des textes de Jules Verne, Édouard Glissant, Sony Labou Tansi, Nancy Huston et Pierre Bergounioux. Pour éviter l’écueil d’un point de vue moraliste, nous avons privilégié une démarche inductive qui part des textes littéraires plutôt que de principes théoriques, ainsi qu’un processus d’écriture collective. Cette démarche nous a permis de dégager cinq enjeux éthiques de l’écopoétique à partir des textes que nous avions rassemblés : l’exigence de vérité, le lien inextricable entre les êtres humains et les lieux qu’ils habitent, l’importance de l’écriture sensible, de la concrétude du langage et de la coexistence des lieux et des imaginaires, laquelle ne saurait aller sans leur co-résistance .
La recherche et l’écriture de l’histoire en Algérie : réalité et enjeux politiques et mémoriels
Authors: Mohand-Amer Amar
Published: March 2021

Il s’agit dans cette contribution de porter l’attention sur le statut de l’historien et de l’histoire dans une Algérie post-indépendance tiraillée entre la force symbolique et politique du passé immédiat (celui Guerre de libération nationale) et l’émergence de nouveaux acteurs mémoriels. Cette articulation est analysée à l’aune de la narration officielle de l’histoire (le roman national), des tentatives de fragmentation du roman national (la « tragédie nationale » des années 1990), et enfin, de l’émergence du mouvement citoyen du 22 février 2019 (le Hirak).
Jacques Lesourne (1928-2020) . Une méthode au service d’une vision
Authors: Thépot Jacques
Published: March 2021

Jacques Lesourne nous a quittés en mars 2020. Cet article rend hommage à celui qui fut un des économistes les plus féconds de sa génération. Il fait partie de cette lignée d’ingénieur économistes qui a fondé la microéconomie. La diversité de ses travaux – du calcul économique à la prospective puis à l’auto-organisation – trouve sa cohérence dans la méthode et dans la vision d’un économiste qui aura tracé sans relâche les chemins de la réforme.

Characterising Bilateral Trade between sub-Saharan Africa and China: The Specific Role of Institutional Quality
Authors: Didier Laurent , Hoarau Jean-François
Published: March 2021

Une nouvelle dimension du commerce international est apparue depuis ces dernières décennies avec l’essor du commerce Sud-Sud mené par la Chine. L’intérêt grandissant et réciproque entre la Chine et l’Afrique est l’une des principales caractéristiques de ce phénomène dans l’économie mondiale. Ce papier cherche donc à explorer les déterminants du commerce bilatéral entre l’Afrique sub-saharienne (ASS) et la Chine tout en portant une attention particulière au rôle des institutions africaines. Pour ce faire, nous appliquons un modèle de gravité structurel fondé théoriquement et robuste à partir d’un échantillon monde couvrant la période 1996-2012. Nous avons construit des variables d’interaction afin d’étudier comment le commerce sino-africain est influencé par la dimension institutionnelle des pays africains qui est mesurée à la fois par le type de régime politique et la qualité de la gouvernance. Les principaux résultats indiquent qu’un régime démocratique en ASS encourage la hausse des flux commerciaux bilatéraux entre l’ASS et la Chine tandis que l’amélioration du contrôle de la corruption en ASS tend à les détériorer. De manière générale, la qualité institutionnelle en ASS (sauf pour le contrôle de la corruption) est un facteur important dans l’explication du développement des exportations de la Chine vers l’ASS, contrairement aux exportations africaines vers la Chine.
Le romantisme de l’interdisciplinarité
Authors: Vaillant Alain
Published: March 2021

Le romantisme français est marqué à la fois par une passion intellectuelle que l’on dirait aujourd’hui interdisciplinaire, et par un culte particulier rendu à la littérature. On pourrait en dire autant de Romantisme , et des études dix-neuviémistes en général, partagés entre ces deux principales orientations, à la fois complémentaires et concurrentes. Un tel syncrétisme a impliqué aussi bien les sciences de nature que l’ensemble des sciences humaines et sociales, au premier rang desquelles l’histoire culturelle et la sociologie. De 1971 à aujourd’hui, il a pris différentes formes, dont cet article se propose d’esquisser, en trois grandes étapes successives, les principales caractéristiques.
On Tikhonov-type regularization with approximated penalty terms
Authors: Neubauer Andreas
Published: March 2021

In this paper, we deal with (nonlinear) ill-posed problems that are regularized by minimizing Tikhonov-type functionals. If the minimization is tedious for some penalty term \begin{document}$ P_0 $\end{document}, we approximate it by a family of penalty terms \begin{document}$ ({P_\beta}) $\end{document} having nicer properties and analyze what happens as \begin{document}$ \beta\to 0 $\end{document}.

We investigate the discrepancy principle for the choice of the regularization parameter and apply all results to linear problems with sparsity constraints. Numerical results show that the proposed method yields good results.
Cosmopolitiques vitivinicoles, ou pourquoi enlever les guillemets aux vins natures
Authors: Mariani Léo
Published: March 2021

Les vins natures ont connu un essor important ces quinze dernières années. On comprend souvent ce succès que comme un engouement dans l’air du temps, une réponse à des préoccupations environnementales de plus en plus pressantes et, partant, comme l’expression d’une quête mythique et de toutes façons illusoire pour une nature qui n’existe pas. Cet article-essai propose plutôt de les considérer comme un mode pratique et spéculatif d’exploration des possibles, une façon originale de faire relation qui interroge les goûts autant que les normes de gouvernance.
Cognitive penetration and taste predicates: making an exception to the rule
Authors: Bordonaba-Plou David
Published: March 2021

The relevance of cognitive penetration has been pointed out concerning three fields within philosophy: philosophy of science, philosophy of mind, and epistemology. This paper argues that this phenomenon is also relevant to the philosophy of language. First, I will defend that there are situations where ethical, social, or cultural rules can affect our taste perceptions. This influence can cause speakers to utter conflicting contents that lead them to disagree and, subsequently, to negotiate the circumstances of application of the taste predicates they have used to describe or express their taste perceptions. Then, to account for the proper dynamics of these cases, I will develop a theoretical framework build upon two elements: the Lewisian idea of the score of a conversation (Lewis, 1979), and Richard’s (2008) taxonomy of the different attitudes speakers can have in taste disagreements. In a nutshell, I will argue that speakers can accommodate these conflicting contents as exceptions to the rule that determines the circumstances of application of taste predicates.Keywords: Cognitive penetration, Common ground, Circumstances of application, Accommodation, Exceptions, Score of the conversation, Taste predicates.
Contra intuições
Authors: Rolla Giovanni
Published: March 2021

This paper intends to offer a critical evaluation of the role played by intuitions in the mainstream methodology in traditional analytic epistemology. The criticism directed to what I call methodology of evaluation by intuitions shows that epistemologists often idealize the reliability of intuitions when assessing a theory against potential counterexamples, ignoring that the disposition to answer intuitively to a case of concept attribution is bounded to the familiar dimension in which the relevant conceptual competence emerges. Thus, the reliability of intuitions does not necessarily extend to far-fetched cases. Given that the assessment by our intuitions is not sufficient to decide for or against an epistemological theory, I offer a sketch for a pragmatic and naturalized conception of theoretical decision-making in epistemology.Key-words: Intuitions, Analytic epistemology, Conceptual abilities, Naturalism, Pragmatism.
Brain as agent and conscious mind as action guide: from Libet-style experiments to necessary conditions for free will
Authors: Coelho Jonas Gonçalves
Published: March 2021

Many neuroscientific experiments, based on monitoring brain activity, suggest that it is possible to predict the conscious intention/choice/decision of an agent before he himself knows that. Some neuroscientists and philosophers interpret the results of these experiments as showing that free will is an illusion, since it is the brain and not the conscious mind that intends/chooses/decides. Assuming that the methods and results of these experiments are reliable the question is if they really show that free will is an illusion. To address this problem, I argue that first it is needed to answer three questions related to the relationship between conscious mind and brain: 1. Do brain events cause conscious events? 2. Do conscious events cause brain events? 3. Who is the agent, that is, who consciously intends/chooses/ decides, the conscious mind, the brain, or both? I answer these questions by arguing that the conscious mind is a property of the brain due to which the brain has the causal capacity to interact adaptively with its body, and trough the body, with the physical and sociocultural environment. In other words, the brain is the agent and the conscious mind, in its various forms - cognitive, volitional and emotional - and contents, is its guide of action. Based on this general view I argue that the experiments aforementioned do not show that free will is an illusion, and as a starting point for examining this problem I point out, from some exemplary situations, what I believe to be some of the necessary conditions for free will.Key-words: Agent brain, conscious mind, free will, Libet-style experiments.
