Based on the literature on stakeholder management and family firm dynamics, this research analyses the relationship between three constructs: the identification of business families with their family firms, FFs’ orientation toward key non-family stakeholders, and the achievement of better economic performance. Data analyses from 374 family and non-family members of 173 Spanish FFs show that a high level of family identification with their firms affects the orientation of FFs toward key non-family stakeholders in setting corporate goals and that this orientation (...) will lead to higher economic performance only when it is built on family identification with the firm. Our results also show that the significance of both relationships changes with the degree of family involvement in the management of the FF. (shrink)

This paper inquires into the nature of intertheoretic relations between psychology and neuroscience. This relationship has been characterized by some as one in which psychological explanations eventually will fall away as otiose, overthrown completely by neurobiological ones. Against this view it will be argued that it squares poorly with scientific practices and empirical developments in the cognitive neurosciences. We analyse a case from research on visual perception, which suggests a much more subtle and complex interplay between psychology and neuroscience than (...) a complete take-over of the former by the latter. In the case of vision, cross-theory influences between psychology and neuroscience go back and forth, resulting in refinement in both disciplines. We interpret this case study as showing that: (1) Mutual co-evolution of psychological and neurobiological theories, exemplifying persisting top-down influences from psychology, is a more empirically adequate way to describe psychoneural theory relations than a view on co-evolution, favoured by reductionists, which regards the cross-theory contributions from psychology as merely heuristically useful with no enduring influence on neurobiological theorizing; (2) In research on vision, discovering (or hypothesizing) the neural basis of functions vindicates psychological approaches, it does not eliminate them; (3) Current work on vision shows that many perceptual phenomena must be understood in terms of dynamical interactions between an observer and his/her environment. Therefore, we argue that internalist characterizations of the visual system must be supplemented with externalist accounts that address these reciprocal observer-environment interactions involved in vision. Such processes seem quite different from (internal) cellular and molecular ones, and as such seem to lie outside the scope of neuroscientific inquiry. We conclude that psychoneural reduction or elimination is implausible as a meta-theoretical prediction of theory choice in empirical work. Instead, this case study of vision shows that both psychology and neuroscience contribute to, and complement one another in the study of visual perception. (shrink)

Scholars and policymakers have increasingly advocated to engage citizens more substantially in the development of science and technology. However, to a large extent it has remained unknown how citizens can contribute to technology development. In this study, we systematically characterized citizens’ contributions in the development of nanotechnology for health. We explored to which technology aspects citizens are able to provide suggestions on and on which values their suggestions are based. Fifty citizens in the Netherlands were asked to discuss different applications (...) of nanotechnology for health. They were divided over eight focus groups, which lasted approximately 6.5h each. The citizens were able to contribute to various technology aspects; they mainly focused on the technologies’ implementation and use, they paid some attention to the development and system aspects, and also addressed, but less, the design and communication aspects. Their suggestions were often derived from concerns about the potential effects of the technologies and were predominantly based on the values of well-being, autonomy, and privacy. (shrink)

The women’s liberation movements that emerged in Britain in the late 1960s are rarely thought of through their relationship with technology and technical knowledge. To overlook this is to misunderstand the movement’s social, cultural and economic interventions; it also understates how the technical environment conditioned the emergence of autonomous, women-centred politics. This article draws on archival evidence to demonstrate how the autonomous women’s liberation movement created experimental social contexts that enabled de-skilled, feminised social classes to confront their technical environment and (...) the deficits they experienced within it. The context for forging such politics was the workshop. More than a one-off, skill-sharing event, the workshop was a mobile habitus, adapted from a Marxist craft politics that prioritised the distribution of collective knowledge and responsibility and enabled the realisation of women's self-determination and autonomy. The workshop was discursively extended through women-authored publications in the 1970s and 1980s and designated a specific orientation within knowledge that supported women to practise a range of technical knowledge and gain expertise. An important, and largely forgotten political legacy of women's liberation is its world-making activisms: how it created social contexts that supported de-skilled, feminised classes to substantially intervene, shape and re-build their environments. Such histories can inspire how we practise politics today within an environment characterised, some theorists claim, by dramatic scales of de-skilling and dispossession. (shrink)

BackgroundCRISPR-Cas9, a technology enabling modification of the human genome, is developing rapidly. There have been calls for public debate to discuss its ethics, societal implications, and governance. So far, however, little is known about public attitudes on CRISPR-Cas9. This study contributes to a better understanding of public perspectives by exploring the various holistic perspectives Dutch citizens have on CRISPR-Cas9.MethodsThis study used Q methodology to identify different perspectives of Dutch citizens (N = 30) on the use of CRISPR-Cas9. The Q-sort method (...) aims at segmenting audiences based on the structural characteristics of their perspectives. Participants individually ranked 32 statements about CRISPR-Cas9 and discussed their rankings in small groups. By-person factor analysis was performed using PQMethod. Participants’ contributions to the discussions were used to further make sense of the audience segments identified.ResultsFive perspectives on CRISPR-Cas9 were identified: (1) pragmatic optimism (2) concerned scepticism; (3) normative optimism; (4) enthusiastic support; and (5) benevolent generalism. Each perspective represents a unique position motivated by different ranking rationales. Sorting rationales included improving health, preventing negative impacts on society, and fear of a slippery slope. Overall, there is broad, but not universal support for medical uses of CRISPR-Cas9.ConclusionsResearch on CRISPR-Cas9 should prioritise the broadly supported applications of the technology. Research and public debates on CRISPR-Cas9, its uses, its broader implications, and the governance of CRISPR-Cas9 are recommended. A discourse that includes all perspectives can contribute to the embedding of future uses of CRISPR-Cas9 in society. This study shows that Q methodology followed by group discussions enables citizens to contribute meaningfully to discourses about research. (shrink)

This work presents the concepts of translation and conservative translation between logics. By using algebraic semantics we introduce several conservative translations involving the classical propositional calculus and the many-valued calculi of Post and Lukasiewicz.

In this paper we will analyze the concept of incoherency that has been put forward by Jesper Juul in Half-Real (2005). Juul provides a paradigmatic example of an incoherency in the game Donkey Kong. The main character of the narrative, Mario, can die and subsequently reappear at the beginning of the level. However, when pressed to describe the narrative of the game, most players would not say that Mario ever died. The respawn is attributed to the game rules instead. Juul (...) calls this phenomenon an incoherency of the game’s fictional world. We claim that the precise nature of the concept of incoherency is unclear, and that Juul's connection between incoherency and contradictions is incorrect. Furthermore, we argue that Wesp incorrectly identifies the concept with 'incompleteness' in his response to Juul (Wesp, 2014). Our clarification argues that what is noteworthy in 'incoherency' is not some aspect of the fictional world, like it being contradictory or incomplete, but how the player interprets the fiction. Subsequently, we provide an explanation for what underlies an incoherency by adopting the principle of charity (Davidson 1973). Lastly we discuss how a proper understanding of incoherency can help game designers and how it relates to ludonarrative dissonance (Hocking, 2009). (shrink)

In De Partibus Animalium I Aristotle sets out his philosophy of biology, discussing cause, necessity, soul, genus, and species, definition by logical division, and general methodology. In De Generatione Animalium I he applies his hylomorphic philosophy to the problem of animal reproduction. The translation is close, and includes passages from De Generatione Animalium II which complete Aristotle's theory of reproduction. The notes interpret Aristotle's arguments and discuss his views on major issues such as natural teleology. The original edition was published (...) in 1972. (shrink)

Le P. D. M. De Petter, o.p., fondateur de cette revue dont il assuma la direction jusqu'à sa mort, survenue le 6 avril 1971, publia pendant sa vie divers articles qui ont suscité, à bon droit, l'intérêt du public philosophique. Ces études demeurent cependant fragmentaires par rapport à sa vision philosophique globale, telle qu'elle est exprimée dans ses cours non publiés. Elles ne reçoivent d'ailleurs leur pleine signification qu'à partir de cette vue d'ensemble. Le présent exposé a pour objectif d'initier (...) les lecteurs aux idées maîtresses de cette œuvre. Il n'a par conséquent d'autre prétention que de rendre fidèlement la pensée du P. De Petter. Il s'agit surtout de deux cours, qui sont étroitement liés : l'un d'anthropologie, l'autre de métaphysique. Le premier constitue le fondement du deuxième lequel, à son tour, complète le premier, en sorte que les deux forment une parfaite unité. De Petter révèle à travers ses cours une ligne de pensée très personnelle et originale. Sans doute en était-il conscient et il n'hésita pas à remettre en question toute la philosophie occidentale. Il y décelait une double erreur : d'une part une vision défectueuse et unilatérale de l'unité complexe de l'homme, d'autre part une interprétation insuffisante de l'ouverture humaine sur la réalité en soi et indépendante. En ce qui concerne le premier point, De Petter insiste sur le dualisme qui domine, quasiment sans contestation, toute la philosophie occidentale, et qui n'est contredit que par l'antidualisme des phénoménologues ; d'autre part il souligne les déficiences de cet antidualisme. Le dualisme n'a pas su rendre compte de l'unité humaine, tandis que l'antidualisme l'exagérait au point d'oublier la complexité de l'homme. En ce qui concerne le second point – l'ouverture humaine sur la réalité en soi – De Petter insiste sur le conceptualisme de toute la philosophie jusqu'à Kant. L'erreur de celui-ci consistait à considérer les concepts comme l'expression adéquate de la réalité elle-même, qu'ils tendaient à supplanter. Ensuite, il signale la réduction de l'être à l'être-pour-moi, prônée depuis Kant. Sur ce point également, la position de De Petter consiste à refuser les deux erreurs mentionnées. Aux phénoménologues, il imprunta tous les facteurs qui relativisent la connaissance humaine, mais à son avis l'affirmation de tout relativisme reste en deça de sa propre implication. Cette affirmation, en effet, prouve l'intentionalité foncière de la conscience sur la réalité même. C'est par cette intentionalité que la métaphysique devient possible. Celle-ci pourtant devra s'accorder au réalisme tel que De Petter le conçoit. Par ce réalisme il faut comprendre que la conscience humaine, à travers toutes les formes de relativité, vise l'absolu sans pouvoir y accéder. Dans cette ligne de pensée, la métaphysique ne fera que se rapprocher du mystère de la réalité toujours inaccessible. Sera-t-elle pour autant une métaphysique du silence ? Non pas. De Petter estime que le mystère de Dieu se montre – en tant que profondeur insondable – à travers l'insuffisance, la contingence ou le vide intérieur de notre monde. Signalons, pour terminer, que De Petter avance dans ses cours, une critique perspicace et profonde des thèses principales de l'anthropologie et de la métaphysique scolastiques. (shrink)

Context. The identification of the sources that reionized the Universe and their specific contribution to this process are key missing pieces of our knowledge of the early Universe. Faint star-forming galaxies may be the main contributors to the ionizing photon budget during the epoch of reionization, but their escaping photons cannot be detected directly due to inter-galactic medium opacity. Hence, it is essential to characterize the properties of faint galaxies with significant Lyman continuum photon leakage up to z 4 to (...) define indirect indicators allowing analogues to be found at the highest redshift. Aims. Long gamma-ray bursts explode typically in star-forming regions of faint, star-forming galaxies. Through LGRB afterglow spectroscopy it is possible to detect directly LyC photons. Our aim is to use LGRBs as tools to study LyC leakage from faint, star-forming galaxies at high redshift. Methods. Here we present the observations of LyC emission in the afterglow spectra of GRB 191004B at z = 3:5055, together with those of the other two previously known LyC-emitting LGRB, to determine their LyC escape fraction and compare their properties. Results. From the afterglow spectrum of GRB 191004B we determine a neutral hydrogen column density at the LGRB redshift of og =17:2 0:15, and negligible extinction. The only metal absorption lines detected are C iv and Si iv. In contrast to GRB 050908 and GRB 060607A, the host galaxy of GRB 191004B displays significant Ly emission. From its Ly emission and the non-detection of Balmer emission lines we constrain its star-formation rate to 1 SFR 4:7 M yr. 1. We fit the Ly emission with a shell model and find parameters values consistent with the observed ones. The absolute LyC escape fractions we find for GRB 191004B, GRB 050908 and GRB 060607A are of 0:35+0:10.0:11, 0:08+0:05.0:04 and :20+0:05.0:05, respectively. We compare the LyC escape fraction of LGRBs to the values of other LyC emitters found from the literature, showing that LGRB afterglows can be powerful tools to study LyC escape for faint high-redshift star-forming galaxies. Indeed we could push LyC leakage studies to much higher absolute magnitudes. The host galaxies of the three LGRB presented here have all M1600 >.19:5 mag, with the GRB 060607A host at M1600 >.16 mag. LGRB hosts may therefore be particularly suitable for exploring the ionizing escape fraction in galaxies that are too faint or distant for conventional techniques. Furthermore the time investment is very small compared to galaxy studies. (shrink)

Atualmente, biotecnologias são empregadas na forma de protocolos a fim de sincronizar o crescimento folicular e a ovulação, bem como permitir que vacas atuem como receptoras de embriões visando melhorar o potencial genético do rebanho. O objetivo desse estudo foi avaliar o efeito da utilização de implantes intravaginais de progesterona de 1º, 2º e 3º uso no protocolo de transferência de embriões em tempo fixo (TETF) sobre a taxa de prenhez em receptoras girolandas. O experimento ocorreu em uma fazenda localizada (...) no município de São Sebastião do Maranhão (MG). Foram utilizadas 74 vacas submetidas aos seguintes protocolos: No dia 0 (D0) administrou-se 2 ml de 17β-Estradiol e progesterona e foi colocado o implante intravaginal de progesterona. Estes implantes foram colocados de forma aleatória, sendo de 1° uso (grupo 1; n=15), 2° (grupo 2; n=24) ou 3° (grupo 3; n=35).No D8, os implantes foram retirados e administrou-se 2 ml PGF2α; 1,5 ml de eCG e 1 ml de 17β-Estradiol e progesterona. A inovulação dos embriões in vitroo correu no D (16) para todas as vacas que apresentaram um corpo lúteo. As variáveis qualitativas (prenhe ou não prenhe) foram comparadas em tabelas de contingência e analisadas pelo teste de qui-quadrado a 5% de probabilidade. Neste estudo não houve diferença estatística entre os grupos protocolados em relação ao aproveitamento como receptoras: 1º uso (53,3%), 2º (79,2%) e 3º (68,65). Ademais, observou-se uma taxa de prenhez entre os grupos de 37,5% para o 1º uso, 42,1% para o 2º e 33,3% para o 3º (P>0,05). Dentre as vantagens ao reaproveitamento dos implantes multiusos destaca-se a redução dos custos dos protocolos hormonais, já que a progesterona é o hormônio mais oneroso, desta forma, a maximização do uso reduz o valor final do protocolo sem prejuízos a taxa de prenhez.

The generic Bohmian trajectories are calculated for an isolated particle in an approximate energy eigenstate, for an arbitrary one-dimensional potential well. It is shown that the necessary and sufficient condition for there to be a negligible probability of the trajectory deviating significantly from the classical trajectory at any stage in the motion is that the state be a narrowly localised wave packet. The properties of the Bohmian trajectories are compared with those in the interpretation recently proposed by García de Polavieja. (...) The reasons why the latter tend to be much more nearly classical are discussed. The implications for other trajectory interpretations are considered. (shrink)
