In this paper we study the Kolmogorov complexity for non-effective computations, that is, either halting or non-halting computations on Turing machines. This complexity function is defined as the length of the shortest input that produce a desired output via a possibly non-halting computation. Clearly this function gives a lower bound of the classical Kolmogorov complexity. In particular, if the machine is allowed to overwrite its output, this complexity coincides with the classical Kolmogorov complexity for halting computations relative to the first (...) jump of the halting problem. However, on machines that cannot erase their output –called monotone machines–, we prove that our complexity for non effective computations and the classical Kolmogorov complexity separate as much as we want. We also consider the prefix-free complexity for possibly infinite computations. We study several properties of the graph of these complexity functions and specially their oscillations with respect to the complexities for effective computations. (shrink)

We define a program size complexity function $H^\infty$ as a variant of the prefix-free Kolmogorov complexity, based on Turing monotone machines performing possibly unending computations. We consider definitions of randomness and triviality for sequences in ${\{0,1\}}^\omega$ relative to the $H^\infty$ complexity. We prove that the classes of Martin-Löf random sequences and $H^\infty$-random sequences coincide and that the $H^\infty$-trivial sequences are exactly the recursive ones. We also study some properties of $H^\infty$ and compare it with other complexity functions. In particular, $H^\infty$ (...) is different from $H^A$, the prefix-free complexity of monotone machines with oracle A. (shrink)

We consider the question of randomness of the probability ΩU[X] that an optimal Turing machine U halts and outputs a string in a fixed set X. The main results are as follows: ΩU[X] is random whenever X is $\Sigma _{n}^{0}$-complete or $\Pi _{n}^{0}$-complete for some n ≥ 2. However, for n ≥ 2, ΩU[X] is not n-random when X is $\Sigma _{n}^{0}$ or $\Pi _{n}^{0}$ Nevertheless, there exists $\Delta _{n+1}^{0}$ sets such that ΩU[X] is n-random. There are $\Delta _{2}^{0}$ sets (...) X such that ΩU[X] is rational. Also, for every n ≥ 1, there exists a set X which is $\Delta _{n+1}^{0}$ and $\Sigma _{n}^{0}$-hard such that ΩU[X] is not random. We also look at the range of ΩU as an operator. We prove that the set {ΩU[X]: X ⊆ 2<ω} is a finite union of closed intervals. It follows that for any optimal machine U and any sufficiently small real r, there is a set X ⊆ 2<ω recursive in ∅′ ⊕ r, such that ΩU[X] = r. The same questions are also considered in the context of infinite computations, and lead to similar results. (shrink)

Rare copy number variants have a prominent role in the aetiology of schizophrenia and other neuropsychiatric disorders. Substantial risk for schizophrenia is conferred by large CNVs at several loci, including microdeletions at 1q21.1, 3q29, 15q13.3 and 22q11.2 and microduplication at 16p11.2. However, these CNVs collectively account for a small fraction of cases, and the relevant genes and neurobiological mechanisms are not well understood. Here we performed a large two-stage genome-wide scan of rare CNVs and report the significant association of copy (...) number gains at chromosome 7q36.3 with schizophrenia. Microduplications with variable breakpoints occurred within a 362-kilobase region and were detected in 29 of 8,290 patients versus 2 of 7,431 controls in the combined sample. All duplications overlapped or were located within 89 kilobases upstream of the vasoactive intestinal peptide receptor gene VIPR2. VIPR2 transcription and cyclic-AMP signalling were significantly increased in cultured lymphocytes from patients with microduplications of 7q36.3. These findings implicate altered vasoactive intestinal peptide signalling in the pathogenesis of schizophrenia and indicate the VPAC2 receptor as a potential target for the development of new antipsychotic drugs. © 2011 Macmillan Publishers Limited.

Parties are central agents of democratic representation. The literature assumes that this function is an automatic consequence of social structure and/or a product of incentives derived from electoral competition. However, representation is contingent upon the organizational structure of parties. The connection between a party and an organized constituency is not limited to electoral strategy; it includes an organic connection through permanent formal or informal linkages that bind party programmatic positions to social groups’ preferences, regardless of the electoral returns. This article (...) analyzes how the Movimiento al Socialismo in Bolivia and the Frente Amplio in Uruguay developed two different forms of relationship with social organizations that result from the interplay of historical factors traceable to the parties’ formative phases and party organizational attributes. Party organizational features that grant voice to grassroots activists serve as crucial mechanisms for bottom-up incorporation of societal interests and demands. (shrink)

Being compassionate and empathic while making rational decisions is expected from healthcare workers across different contexts. But the daily challenges that these workers face, aggravated by the recent COVID-19 crisis, can give rise to compassion and decision fatigue, which affects not only their ability to meet these expectations but has a significant negative impact on their wellbeing. Hence, it is vital to identify factors associated to their exhaustion. Here, we sought to describe levels of compassion and decision fatigue during the (...) pandemic, and to identify factors related to these forms of exhaustion. We collected data using self-reported questionnaires to measure compassion fatigue, decision fatigue, and grit in five intervals from April to November, 2020 (N = 856). Our results showed a negative correlation between grit and compassion and decision fatigue. We also found that under the circumstances studied grit tends to be higher in technicians, nurses, other professionals (psychologists, social workers), and workers at the Emergency Room (ER), and lower in general practitioners. Compassion fatigue tend to be higher for technicians, whereas decision fatigue was lower for specialists, general practitioners, and technicians, and higher for those working at private hospitals.

The concept of fitness has generated a lot of discussion in philosophy of biology. There is, however, relative agreement about the need to distinguish at least two uses of the term: ecological fitness on the one hand, and population genetics fitness on the other. The goal of this paper is to give an explication of the concept of ecological fitness by providing a reconstruction of the theory of natural selection in which this concept was framed, that is, based on the (...) way the theory was put to use in Darwin’s main texts. I will contend that this reconstruction enables us to account for the current use of the theory of natural selection. The framework presupposed in the analysis will be that of metatheoretical structuralism. This framework will provide both a better understanding of the nature of ecological fitness and a more complete reconstruction of the theory. In particular, it will provide what I think is a better way of understanding how the concept of fitness is applied through heterogeneous cases. One of the major advantages of my way of thinking about natural selection theory is that it would not have the peculiar metatheoretical status that it has in other available views. I will argue that in order to achieve these goals it is necessary to make several concepts explicit, concepts that are frequently omitted in usual reconstructions. (shrink)

Philosophical accounts of moral responsibility are standardly framed by two platitudes. According to them, blame requires the presence of a moral defect in the agent and the absence of excuses. In this chapter, this kind of approach is challenged. It is argued that (a) people sometimes violate moral norms due to performance mistakes, (b) it often appears reasonable to hold them responsible for it, and (c) their mistakes cannot be traced to their moral qualities or to the presence of excuses. (...) In the end, the implications for discussions of moral responsibility are discussed. (shrink)

Radical skepticism relies on the hypothesis that one could be completely cut off from the external world. In this paper, I argue that this hypothesis can be rationally motivated by means of a conceivability argument. Subsequently, I submit that this conceivability argument does not furnish a good reason to believe that one could be completely cut off from the external world. To this end, I show that we cannot adequately conceive scenarios that verify the radical skeptical hypothesis. Attempts to do (...) so fall prey to one or another of three pitfalls: they end up incomplete, reveal a deep contradiction or recreate a non-skeptical hypothesis. I use these results to improve upon Pritchard’s recent attempt at undercutting radical skepticism. (shrink)

Austere relationism rejects the orthodox analysis of hallucinations and illusions as incorrect perceptual representations. In this article, I argue that illusions of optimal motion present a serious challenge for this view. First, I submit that austere-relationist accounts of misleading experiences cannot be adapted to account for IOMs. Second, I show that any attempt at elucidating IOMs within an austere-relationist framework undermines the claim that perceptual experiences fundamentally involve relations to mind-independent objects. Third, I develop a representationalist model of IOMs. The (...) proposed analysis combines two ideas: Evans' dynamic modes of presentation and Fine's relational semantics for identity. (shrink)

Resumen: Usualmente se ha asumido que una única distinción puede dar cuenta del rol que cumplen los conceptos en una teoría respecto de la contrastación y respecto de la explicación. Intentaremos mostrar que esta asunción es incorrecta. Por una parte, no hay razones para considerar que esta coincidencia deba darse, y por otra, como se intentará mostrar a partir de varios ejemplos, de hecho, no se da. La base de contrastación de una teoría no tiene por qué coincidir con el (...) explanandum de la teoría. Para defender este punto se asumirá el estructuralismo metateórico. Se extraerán consecuencias para la concepción metateórica presupuesta. Palabras claves: Explicación; contrastación; T-teoricidad; Estructuralismo metateórico; Distinción teórico observacional -/- Title: Explain and test Abstract: It is usually held that one distinction can account for the role that concepts play in a theory regarding both test and explanation. We will demonstrate that this assumption is incorrect. On the one hand, there is no reason to think that this coincidence should exist. On the other, this is not the case, as we will show analysing several examples. The testing basis of a theory does not have to coincide with the explanandum of the theory. To defend this point we will endorse de metatheoretical structuralism. In addition, we will consider some repercussions that this discussion has for the assumed metatheoretical framework. Key-words: Explanation; Test; T-theoreticity; Metatheoretical Structuralism; Theoretical observational distinction . (shrink)

Most human actions are complex, but some of them are basic. Which are these? In this paper, I address this question by invoking slips, a common kind of mistake. The proposal is this: an action is basic if and only if it is not possible to slip in performing it. The argument discusses some well-established results from the psychology of language production in the context of a philosophical theory of action. In the end, the proposed criterion is applied to discuss (...) some well-known theories of basic actions. (shrink)

Philosophers of perception are familiar with the argument from illusion, at least since Hume formulated it to challenge a naïve form of realism. In this paper, I present an analogous argument but in the domain of action. It focuses on slips, a common kind of mistake. But, otherwise, it is structurally similar. The argument challenges some contemporary views about the nature of action inspired by Wittgenstein. The discussion shows how thinking about these common mistakes helps illuminate aspects of human agency (...) that tend to be overlooked whenever too much emphasis is placed on the rationality of human actions.

RESUMEN La importancia de Rousseau para el surgimiento del idealismo poskantiano ha sido poco investigada. Oculta en gran medida por la recepción kantiana, la obra del pensador ginebrino parece tener tan solo una importancia accesoria. A partir del análisis interpretativo de las fuentes y su comparación con las principales doctrinas de Rousseau, nuestro trabajo busca mostrar, valiéndonos de las obras de Hölderlin y Hegel de la época de Tubinga y de los años inmediatamente posteriores (1791-1795), que la influencia del pensador (...) ginebrino posee una importancia decisiva para concebir el programa artístico y religioso de los autores estudiados. El análisis nos permitirá comprender que el mencionado autor no representa la figura de un filósofo, menos la de un ilustrado, sino más bien la de un sabio, el portador de una doctrina práctica cuyo principio fundamental se encuentra en la suprema dignidad del hombre y en la idea de libertad entendida como autonomía. ABSTRACT Rousseau's importance for the postkantian idealism has been poorly researched. Hidden by the Kantian interpretation, the work of the Geneva thinker seems to have no relevant influence. Departing from an interpretative analysis of the literary sources and a comparison with the main doctrines, our paper aims to show, using Hölderlin and Hegel's Tubingen and the immediately subsequent works (1791-1795), that Rousseau's influence has a decisive importance to understand the artistic and religious program of our authors. This analysis will allow us to understand that Rousseau is not a philosopher, nor an enlightenment figure, but rather a wise man, the bringer of a practical doctrine whose main principle consisted in supreme human dignity and the idea of freedom interpreted as autonomy.

Deep brain stimulation (DBS) is a developing technology. New generations of DBS technology are already in the pipeline, yet this particular fact has been largely ignored among ethicists interested in DBS. Focusing only on ethical concerns raised by the current DBS technology is, albeit necessary, not sufficient. Since current bioethical concerns raised by a specific technology could be quite different from the concerns it will raise a couple of years ahead, an ethical analysis should be sensitive to such alterations, or (...) it could end up with results that soon become dated. The goal of this analysis is to address these changing bioethical concerns, to think ahead on upcoming and future DBS concerns both in terms of a changing technology and changing moral attitudes. By employing the distinction between inherent and noninherent bioethical concerns we identify and make explicit the particular limits and potentials for change within each category, respectively, including how present and upcoming bioethical concerns regarding DBS emerge and become obsolete. Many of the currently identified ethical problems with DBS, such as stimulation-induced mania, are a result of suboptimal technology. These challenges could be addressed by technical advances, while for instance perceptions of an altered body image caused by the mere awareness of having an implant may not. Other concerns will not emerge until the technology has become sophisticated enough for new uses to be realized, such as concerns on DBS for enhancement purposes. As a part of the present analysis, concerns regarding authenticity are used as an example. (shrink)

Does home-based family involvement influence academic performance? To answer this question, a case study research was carried out with 96 children from all six levels of primary education at a public school, and their families. Data regarding home-based family involvement were collected using a questionnaire. Academic achievement was measured from school marks. The results reveal that, apart from two of the factors considered, home–family involvement as a whole is not significantly related to academic achievement. These two factors are access to (...) informal education resources and parents’ employment. Family involvement related to the access of children to informal education resources is significantly related to a better academic achievement. Those students with both parents working perform best, and those with none working, worst. Although gender does not appear to significantly influence academic achievement and family involvement, the results show that girls attain better school performance and re... (shrink)

Abstract:Brain–computer interfaces (BCIs) can enable communication for persons in severe paralysis including locked-in syndrome (LIS); that is, being unable to move or speak while aware. In cases of complete loss of muscle control, termed “complete locked-in syndrome,” a BCI may be the only viable solution to restore communication. However, a widespread ignorance regarding quality of life in LIS, current BCIs, and their potential as an assistive technology for persons in LIS, needlessly causes a harmful situation for this cohort. In addition (...) to their medical condition, these persons also face social barriers often perceived as more impairing than their physical condition. Through social exclusion, stigmatization, and frequently being underestimated in their abilities, these persons are being locked out in addition to being locked-in. In this article, we (1) show how persons in LIS are being locked out, including how key issues addressed in the existing literature on ethics, LIS, and BCIs for communication, such as autonomy, quality of life, and advance directives, may reinforce these confinements; (2) show how these practices violate the United Nations Convention on the Rights of Persons with Disabilities, and suggest that we have a moral responsibility to prevent and stop this exclusion; and (3) discuss the role of BCIs for communication as one means to this end and suggest that a novel approach to BCI research is necessary to acknowledge the moral responsibility toward the end users and avoid violating the human rights of persons in LIS.

Conceptual congruency effects are biases induced by an irrelevant conceptual dimension of a task (e.g., location in vertical space) on the processing of another, relevant dimension (e.g., judging words’ emotional evaluation). Such effects are a central empirical pillar for recent views about how the mind/brain represents concepts. In the present paper, we show how attentional cueing (both exogenous and endogenous) to each conceptual dimension succeeds in modifying both the manifestation and the symmetry of the effect. The theoretical implications of this (...) finding are discussed. (shrink)

The case of Charlie Gard sparked an ongoing public and academic debate whether in court decisions about medical treatment for children in England & Wales the best interests test should be replaced by a harm threshold. However, the literature has scantly considered (1) what the impact of such a replacement would be on future litigation and (2) how a harm threshold should be introduced: for triage or as standard for decision-making. This article directly addresses these gaps, by first analysing reported (...) cases in England & Wales about medical treatment in the context of a S31 order, thus using a harm threshold for triage and second comparing court decisions about medical treatment for children in England & Wales based on the best interest test with Dutch and German case law using a harm threshold. The investigation found that whilst no substantial increase of parental discretion can be expected an introduction of a harm threshold for triage would change litigation. In particular, cases in which harm is limited, currently only heard when there are concerns about parental decision-making, may be denied a court hearing as might cases in which the child has lost their capacity to suffer. Applying a harm threshold for triage in decisions about withholding or withdrawing life-sustaining treatment might lead to a continuation of medical treatment that could be considered futile.

In the aftermath of the Fukushima power plant disaster, autoradiography became an increasingly widespread artistic technique for producing cameraless photography. By exposing photographic film directly using contaminated objects and materials, contemporary artists autoradiograph the geopolitics and local histories of atomic contamination due to bombing, testing, nuclear reactor explosions, mining or uranium disposal cells. In my article, I discuss the implications these autoradiographic works have for the concept of photography by drawing on Timothy Morton’s notion of hyperobjects. Being hyperobjective, radioactivity confronts (...) human beings with a vast non-human temporality, which, in turn, necessitates a shift in our understanding of photography. While photo theory has often been modelled on snapshot photography, privileging instantaneity and pastness, autoradiography is a durational and pluri-temporal procedure that points emphatically towards the future and invites us to reconceptualize the basis of photographic ontology.

A nation cannot exist without national culture and national self-consciousness. These concepts are decisive in the development of the nation. Values are the priorities of any nation, determined by its culture and self-awareness. The national cool is the basis for the formation and development of national self-consciousness. The aim is to analyze the influence of national culture on the formation of national consciousness. Justify their objective and subjective factors of formation, which are based on the motivational core of personality behavior. (...) National culture and national self-consciousness are the main features of a nation, without which it cannot exist and develop as a whole. National culture and national self-consciousness are one whole of the spiritual world of nations and nationalities. The development of national culture and national self-consciousness is an objective regularity. Naturally, contradictions in this process will exist and demand their resolution or escalate into conflicts. With a timely solution, they will play the role of an indicator of national development.
