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)

Using possibly infinite computations on universal monotone Turing machines, we prove Martin-Löf randomness in ∅' of the probability that the output be in some set.

Let [Formula: see text] be an integer. We show that the set of real numbers that are Poisson generic in base [Formula: see text] is [Formula: see text]-complete in the Borel hierarchy of subsets of the real line. Furthermore, the set of real numbers that are Borel normal in base [Formula: see text] and not Poisson generic in base [Formula: see text] is complete for the class given by the differences between [Formula: see text] sets. We also show that the (...) effective versions of these results hold in the effective Borel hierarchy. (shrink)

We obtain a large class of significant examples of n-random reals (i.e., Martin-Löf random in oracle $\varphi ^{(n - 1)} $ ) à la Chaitin. Any such real is defined as the probability that a universal monotone Turing machine performing possibly infinite computations on infinite (resp. finite large enough, resp. finite self-delimited) inputs produces an output in a given set O ⊆(ℕ). In particular, we develop methods to transfer $\Sigma _n^0 $ or $\Pi _n^0 $ or many-one completeness results of (...) index sets to n-randomness of associated probabilities. (shrink)

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)

At the outset of an ethnographic inquiry, we navigated national and international resources to search for theoretical and practical guidance on obtaining parents and children’s informed consent/assent. While much theoretical guidance debating ethical issues to children’s participation in research was found, a paucity of published papers offering practical guidance on assent processes and/or visual representations of child assent forms and information sheets was discovered. The purpose of this article is to describe our experiences, both theoretically and practically, of negotiating the (...) process of obtaining informed consent and assent with parents and children for a non-therapeutic qualitative research study. We hope this article instigates a platform for others to explicate their experience and contributes to the construction of a coherent body of knowledge which will clearly delineate important elements that must be considered when negotiating children’s agreement to participate in research.

Background:Ethical competence in nursing practice helps clinical nurses to think critically, analyse issues, make ethical decisions, solve ethical problems and behave ethically in their daily work. Thus, ethical competence contributes to the promotion of high-quality care. However, studies on ethical competence in Malawi are scanty.Objectives:The aim of this study was to explore ethical competence among clinical nurses in selected hospitals in Malawi.Methodology:A cross-sectional survey was conducted in four selected hospitals in Malawi with a sample of 271 clinical nurses. Data were (...) collected using self-administered questionnaires, which included a Moral Competence Scale for Home Care Nurses. Descriptive statistics and logistic regression were computed for the dataset using STATA version 12.0.Ethical consideration:The study protocol complied with all ethical requirements and was approved by the College of Medicine Research Ethics Committee under the University of Malawi.Results:The clinical nurses in Malawi are ethically competent. However, there is a significantly high number (p 0.05). Three determinants of high ethical competence level (strong will, judgement skills and recognition of discrepancy of intention) were identified through a reduced model after stepwise logistic regression analysis. Furthermore, results show that indicators of ethical competence include caring, confidentiality and observance of nurses dressing code. The study has also confirmed that the Moral Competence Scale for Home Care Nurses is a reliable tool to assess ethical competence in low-resource settings.Conclusion:The majority of nurses who completed the survey had low ethical competence. However, clinical nurses with high ethical competence level are required to competently manage complex ethical challenges in health facilities. Strategies for enhancing ethical competence such as continuing ethics education, establishment of ethics committees and provision of supportive supervision are recommended to enable nurses in Malawi attain a high level of ethical competence.

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)

Body representations are known to be dynamically modulated or extended through tool use. Here, we review findings that demonstrate the importance of a user's tool experience or expertise for successful tool embodiment. Examining expert tool users, such as individuals who use tools in professional sports, people who use chopsticks at every meal, or spinal injury patients who use a wheelchair daily, offers new insights into the role of expertise in tool embodiment: Not only does tool embodiment differ between novices and (...) experts, but experts may experience enhanced changes to their body representation when interacting with their own, personal tool. The findings reviewed herein reveal the importance of assessing tool skill in future studies of tool embodiment. (shrink)

In this paper, we examine the scientific, legal, and ethical foundations for inclusion of transgender women athletes in competitive sport, drawing on IOC principles and relevant Court of Arbitration for Sport decisions. We argue that the inclusion of trans athletes in competition commensurate with their legal gender is the most consistent position with these principles of fair and equitable sport. Biological restrictions, such as endogenous testosterone limits, are not consistent with IOC and CAS principles. We explore the implications for recognizing (...) that endogenous testosterone values are a ‘natural physical trait’ and that excluding legally recognized women for high endogenous testosterone values constitutes discrimination on the basis of a natural physical trait. We suggest that the justificatory burden for such prima facie discrimination is unlikely to be met. Thus, in place of a limit on endogenous testosterone for women, we argue that ‘legally recognized gender’ is most fully in line with IOC and CAS principles. (shrink)

The presence of stigmatizing language in the electronic health record (EHR) has been used to measure implicit biases that underlie health inequities. The purpose of this study was to identify the presence of stigmatizing language in the clinical notes of pregnant people during the birth admission. We conducted a qualitative analysis on N = 1117 birth admission EHR notes from two urban hospitals in 2017. We identified stigmatizing language categories, such as Disapproval (39.3%), Questioning patient credibility (37.7%), Difficult patient (21.3%), (...) Stereotyping (1.6%), and Unilateral decisions (1.6%) in 61 notes (5.4%). We also defined a new stigmatizing language category indicating Power/privilege. This was present in 37 notes (3.3%) and signaled approval of social status, upholding a hierarchy of bias. The stigmatizing language was most frequently identified in birth admission triage notes (16%) and least frequently in social work initial assessments (13.7%). We found that clinicians from various disciplines recorded stigmatizing language in the medical records of birthing people. This language was used to question birthing people's credibility and convey disapproval of decision‐making abilities for themselves or their newborns. We reported a Power/privilege language bias in the inconsistent documentation of traits considered favorable for patient outcomes (e.g., employment status). Future work on stigmatizing language may inform tailored interventions to improve perinatal outcomes for all birthing people and their families. (shrink)

Husserlian phenomenology of time, as it is developed on theLectures on the Phenomenology of Inner Time Consciousness, shows some difficulties to explain certain temporal experiences. This is the case of the incompatibility between the rigidity of the retentional modification and the effective approach that a subject may have with his memories. On the one hand, according to the Lectures’ explanation, the darkening of the past occurs in an homogeneous way: The more distant an experience is, the lower the clarity of (...) the associated retention. However, our relation with the past is not so direct. Complementing the studies of the Lectureswith those of the Analysis concerning passive synthesiscould allow to explain this kind of temporal phenomena. (shrink)

RESUMEN Aunque las Lecciones de fenomenología de la conciencia interna del tiempo tienen pocas referencias al marco metódico, ciertos pasajes apuntan a la reducción fenomenológica, de modo que su status se diferenciaría del de las Investigaciones lógicas y se acercaría al de Ideas i. Se ha señalado que aun si la reducción es empleada en este texto, no lo sería en su "versión madura". Se busca determinar el estatus metodológico de las Lecciones a partir de una comparación entre los desarrollos (...) metódicos y las descripciones fenomenológicas que se presentan allí y aquellos consignados en Investigaciones e Ideas, teniendo como idea regulativa el esclarecimiento del papel del tiempo en la ampliación del dominio de la fenomenología como conjunto. ABSTRACT Although there are few references to the methodological framework in On the Phenomenology of the Consciousness of Internal Time, certain passages point to the phenomenological reduction. Therefore, its status would differ from that of the Logical Investigations and approach that of Ideas I. Some have argued that the reduction used in this text is not the "mature version" of the same. The article seeks to determine the methodological status of PCIT on the basis of the comparison between the methodological developments and phenomenological descriptions found in this work and those found in Investigations and Ideas. The regulative idea guiding the analysis is the clarification of the role of time in broadening the sphere of phenomenology as a whole. (shrink)

Este trabajo examina diferentes perspectivas docentes para externalizar criterios de evaluación. Se presentan hallazgos de una investigación doctoral que abordan, por una parte, una metodología analítica, que cautela la claridad y transparencia en la comunicación de criterios, segmentando la meta de aprendizaje en pequeñas secuencias, transmitiendo de este modo una idea atomizada acerca del conocimiento. Por otra parte, se explora una visión más holística, sustentada en la interdependencia de los criterios de evaluación, favoreciendo la comprensión del propósito de la tarea (...) en su conjunto. Se analiza la significancia de estos enfoques para la retroalimentación y evaluación formativa. (shrink)

We contribute to feminist and gender scholarship on cultural notions of motherhood by analyzing the importance of motherhood among mothers and non-mothers. Using a national probability sample of U.S. women ages 25-45, we find a continuous distribution of scores measuring perceptions of the importance of motherhood among both groups. Employing OLS multiple regression, we examine why some women place more importance on motherhood, focusing on interests that could compete with valuing motherhood, and controlling for characteristics associated with becoming a mother. (...) Contrary to cultural schemas that view mother and worker identities as competing, we find that education level is not associated with the importance of motherhood for either group and that valuing work success is positively associated with valuing motherhood among mothers. Consistent with feminist explanations for delayed fertility, valuing leisure is negatively associated with valuing motherhood for non-mothers. (shrink)

O objetivo deste artigo é apresentar uma argumentação sobre a possibilidade de se pensar a justiça como uma experiência do i m possível. Parte-se da distinção derridiana entre justiça e direito. Essa distinção trará algumas implicações no que tradicionalmente é entendido como ética. Partindo do jogo ou da différance marcada entre a presença/ausência, pretende-se estabelecer um ponto de diálogo entre Derrida e Levinas. O ponto de aproximação é a questão do terceiro na relação do face a face. Nesse sentido, problematiza-se (...) se a desconstrução pode ser adotada como um possível modo filosófico que fundamente a compreensão da justiça. (shrink)
