This paper presents a new theory of modal reasoning, i.e. reasoning about what may or may not be the case, and what must or must not be the case. It postulates that individuals construct models of the premises in which they make explicit only what is true. A conclusion is possible if it holds in at least one model, whereas it is necessary if it holds in all the models. The theory makes three predictions, which are corroborated experimentally. First, conclusions (...) correspond to the true, but not the false, components of possibilities. Second, there is a key interaction: it is easier to infer that a situation is possible as opposed to impossible, whereas it is easier to infer that a situation is not necessary as opposed to necessary. Third, individuals make systematic errors of omission and of commission. We contrast the theory with theories based on formal rules. (shrink)

Increasing public concern for the welfare of fish species that human beings use and exploit has highlighted the need for better understanding of the cognitive status of fish and of their ability to experience negative emotions such as pain and fear. Moreover, studying emotion and cognition in fish species broadens our scientific understanding of how emotion and cognition are represented in the central nervous system and what kind of role they play in the organization of behavior. For instance, on a (...) macro neuro-architecture level the brains of fish species look dramatically different from those of mammals, while such a dramatic difference does not (always) occur at the level of emotion- and cognition-related behavior. Here, therefore, we discuss the evidence of emotion and cognition in fish species related to underlying neuro-architecture and the role that emotion and cognition play in the organization of behavior. To do so we use a framework encompassing a number of steps allowing a systematic approach to these issues. Emotion and cognition confer on human and non-human animals the capacity to compliment and/or override immediate reflexes to stimuli and so allow a large degree of flexibility in behavior. Systematic research on behavior that in mammals is indicative of emotion and cognition has been conducted in only a few fish species. The data thus far indicate that in these species brain-behavior relationships are not fundamentally different from those observed in mammals. Furthermore, data from other studies show evidence that behavior patterns related to emotion and cognition vary between fish species as well within fish species, related to sex and life history stage for example. From a welfare perspective, knowledge of such variability will potentially help us to design optimal living conditions for fish species kept by humans. (shrink)

Our objective is to understand how parents and children perceive their roles in decision making about research participation. Forty-five children (ages 4-15 years) with or without a chronic condition and 21 parents were the participants. A semistructured interview assessed perceptions of up to 4 hypothetical research scenarios with varying levels of risk, benefit, and complexity. Children were also administered the Peabody Picture Vocabulary Test, Third Edition, to assess verbal ability, as a proxy for the child's cognitive development. The audiotaped interviews (...) were transcribed and analyzed for themes related to parent and child decision-making roles. Both parents and children varied in their perceptions of decision-making roles. Child perceptions of parental influence on decision making as knowledge-based increased with cognitive development, whereas perceptions of parental influence as power-based decreased. Both children and parents commented that they would collaborate with each other when making decisions. Collaborative decision making appeared to increase with cognitive development. These findings suggest that approaches to child assent and parent permission should consider the parent-child relationship and how children and families typically make decisions. Future research is necessary to explain variation in the process of research decision making across children and families, explore the role of collaboration on children's decision-making skills, and understand developmental trajectories and mechanisms related to research decision making.

This narrative review summarizes the empirical literature on children's competence for consent and assent in research and treatment settings. Studies varied widely regarding methodology, particularly in the areas of participant sampling, situational context studied (e.g., psychological versus medical settings), procedures used (e.g., lab-based vs. real-world approaches), and measurement of competence. This review also identified several fundamental dilemmas underlying approaches to children's informed consent. These dilemmas, including autonomy versus best interests approaches, legal versus psychological or ethical approaches, child- versus family-based approaches, (...) and approaches that emphasize consent versus those that emphasize assent, have implications for the measurement of children's competence and interpretation of findings. Recommendations for future research in the area of children's informed consent include the use of diverse samples and control groups, development of multidimensional and standardized measures of competence, utilization of observational methods and longitudinal designs, examination of noncognitive aspects of children's competence, and comparison of children's competence for treatment and research decisions.

Our primary focus is on analysis of the concept of voluntariness, with a secondary focus on the implications of our analysis for the concept and the requirements of voluntary informed consent. We propose that two necessary and jointly sufficient conditions must be satisfied for an action to be voluntary: intentionality, and substantial freedom from controlling influences. We reject authenticity as a necessary condition of voluntary action, and we note that constraining situations may or may not undermine voluntariness, depending on the (...) circumstances and the psychological capacities of agents. We compare and evaluate several accounts of voluntariness and argue that our view, unlike other treatments in bioethics, is not a value-laden theory. We also discuss the empirical assessment of individuals? perceptions of the degrees of noncontrol and self-control. We propose use of a particular Decision Making Control Instrument. Empirical research using this instrument can provide data that will help establish appropriate policies and procedures for obtaining voluntary consent to research. (shrink)

When listening to degraded speech, such as speech delivered by a cochlear implant, listeners make use of top-down linguistic knowledge to facilitate speech recognition. Lexical knowledge supports speech recognition and enhances the perceived clarity of speech. Yet, the extent to which lexical knowledge can be used to effectively compensate for degraded input may depend on the degree of degradation and the listener’s age. The current study investigated lexical effects in the compensation for speech that was degraded via noise-vocoding in younger (...) and older listeners. In an online experiment, younger and older normal-hearing listeners rated the clarity of noise-vocoded sentences on a scale from 1 to 7. Lexical information was provided by matching text primes and the lexical content of the target utterance. Half of the sentences were preceded by a matching text prime, while half were preceded by a non-matching prime. Each sentence also consisted of three key words of high or low lexical frequency and neighborhood density. Sentences were processed to simulate CI hearing, using an eight-channel noise vocoder with varying filter slopes. Results showed that lexical information impacted the perceived clarity of noise-vocoded speech. Noise-vocoded speech was perceived as clearer when preceded by a matching prime, and when sentences included key words with high lexical frequency and low neighborhood density. However, the strength of the lexical effects depended on the level of degradation. Matching text primes had a greater impact for speech with poorer spectral resolution, but lexical content had a smaller impact for speech with poorer spectral resolution. Finally, lexical information appeared to benefit both younger and older listeners. Findings demonstrate that lexical knowledge can be employed by younger and older listeners in cognitive compensation during the processing of noise-vocoded speech. However, lexical content may not be as reliable when the signal is highly degraded. Clinical implications are that for adult CI users, lexical knowledge might be used to compensate for the degraded speech signal, regardless of age, but some CI users may be hindered by a relatively poor signal.

It was, until recently, accepted that the two classes of acetylcholine (ACh) receptors are distinct in an important sense: muscarinic ACh receptors signal via heterotrimeric GTP binding proteins (G proteins), whereas nicotinic ACh receptors (nAChRs) open to allow flux of Na+, Ca2+, and K+ ions into the cell after activation. Here we present evidence of direct coupling between G proteins and nAChRs in neurons. Based on proteomic, biophysical, and functional evidence, we hypothesize that binding to G proteins modulates the activity (...) and signaling of nAChRs in cells. It is important to note that while this hypothesis is new for the nAChR, it is consistent with known interactions between G proteins and structurally related ligand‐gated ion channels. Therefore, it underscores an evolutionarily conserved metabotropic mechanism of G protein signaling via nAChR channels.Also watch the Video Abstract. (shrink)

Although research on corporate social responsibility has grown steadily, little research has focused on CSR at the individual level. In addition, research on the role of environmental friendly organizational citizenship behaviors within CSR initiatives is scarce. In response to this gap and recent calls for further research on both individual and organizational variables of employees’ environmentally friendly, or green, behaviors, this article sheds light on the influence of these variables on three types of green employee behaviors simultaneously: recycling, energy savings, (...) and printing reduction. An initial theoretical model identifies both individual and organizational variables that affect different types of green behaviors as a stepping stone for further research. The results reveal managerial implications and future research directions on the design of effective social marketing interventions that motivate different types of OCBs in the workplace. In particular, the results suggest that creating separate interventions for each type of environmental behavior, as well as for each organization, sector, and type of organization , is necessary. In addition, this research illustrates patterns of attitudes, perceptions, and behaviors by exploring individual and organizational variables and behaviors across seven different organizations belonging to different sectors.

We show that the theory, consisting of the usual axioms of but with the power set axiom removed—specifically axiomatized by extensionality, foundation, pairing, union, infinity, separation, replacement and the assertion that every set can be well‐ordered—is weaker than commonly supposed and is inadequate to establish several basic facts often desired in its context. For example, there are models of in which ω1 is singular, in which every set of reals is countable, yet ω1 exists, in which there are sets of (...) reals of every size, but none of size, and therefore, in which the collection axiom fails; there are models of for which the Łoś theorem fails, even when the ultrapower is well‐founded and the measure exists inside the model; there are models of for which the Gaifman theorem fails, in that there is an embedding of models that is Σ1‐elementary and cofinal, but not elementary; there are elementary embeddings of models whose cofinal restriction is not elementary. Moreover, the collection of formulas that are provably equivalent in to a Σ1‐formula or a Π1‐formula is not closed under bounded quantification. Nevertheless, these deficits of are completely repaired by strengthening it to the theory, obtained by using collection rather than replacement in the axiomatization above. These results extend prior work of Zarach. (shrink)

Inception module is one of the most used variants in convolutional neural networks. It has a large portfolio of success cases in computer vision. In the past years, diverse inception flavours, differing in the number of branches, the size and the number of the kernels, have appeared in the scientific literature. They are proposed based on the expertise of the practitioners without any optimization process. In this work, an implementation of population-based incremental learning is proposed for automatic optimization of the (...) hyperparameters of the inception module. This hyperparameters optimization undertakes classification of the MNIST database of handwritten digit images. This problem is widely used as a benchmark in classification, and therefore, the learned best configurations for the Inception module will be of wide use in the deep learning community. In order to reduce the carbon footprint of the optimization process, policies for reducing the redundant evaluations have been undertaken. As a consequence of this work, an evaluation of configurations of the inception module and a mechanism for optimizing hyperparameters in deep learning architectures are stated. (shrink)

In this article, we explicate evidence-based nursing (EBN), critically appraise its framework and respond to nurses’ concern that EBN sidelines the caring elements of nursing practice. We use resources from care ethics, especially Vrinda Dalmiya’s work that considers care as crucial for both epistemology and ethics, to show how EBN is compatible with, and indeed can be enhanced by, the caring aspects of nursing practice. We demonstrate that caring can act as a bridge between ‘external’ evidence and the other pillars (...) of the EBN framework: clinical expertise; patient preferences and values. Drawing on an influential EBN handbook, section 1 presents the aims and features of EBN, including the normative principle that EBN should take place within a ‘context of caring’. We aim to understand this context and whether it can be neatly detached from the EBN framework, as the handbook seems to suggest. In section 2, we highlight the grounds for resistance to EBN from the nursing community, before mounting the argument that nursing practices can be understood fruitfully through feminist care ethics and/or virtue ethics lenses. In section 3, we deepen that analysis using Dalmiya’s concepts of care-knowing and care as a hybrid ethico-epistemic virtue, which are ideally suited to the complex practices of nursing. In section 4, we bring this rich understanding of care into conversation with EBN, showing that its framework cannot be adequately theorised without paying proper attention to care. Caring can be neither an innocuous background assumption of nor an afterthought to the EBN framework. (shrink)

Problematic substance use (PSU) among nurses has wide‐ranging adverse implications. A critical integrative literature review was conducted with an emphasis on building knowledge regarding the influence of structural factors within nurses' professional environments on nurses with PSU. Five thematic categories emerged: (i) access, (ii) stress, and (iii) attitudes as contributory factors, (iv) treatment policies for nurses with PSU, and (v) the culture of the nursing profession. Conclusions were that an overemphasis on individual culpability and failing predominates in the literature and (...) that crucial knowledge gaps exist regarding the influence of structural factors on driving and shaping nurses' substance use.

Questions about how to negotiate belief and non-belief in social and public spheres are attracting an increasing amount of attention from academics in a range of disciplines, and from concerned members of the public. This volume addresses the emergence of ‘new atheism’ and the developing ‘spiritual but not religious’ phenomenon. Avoiding simplistic accounts of atheism, and of religious belief, it provides readers with insight into a wide range of nuances within theism and a-theism, as well as spiritual practice and faith. (...) The chapters by an international panel of contributors focus on topics such as: a typology or cartography of atheisms and agnosticism; contrasting types of atheism within Christianity and Buddhism; questions about cognitive and doxastic stances in atheisms; theist rejections of and atheist embracing of ‘God’; atheist aesthetics. Reaching beyond the Christian tradition, the book will be of particular interest to scholars of the philosophy of religion, as well as religious studies and theology more generally. (shrink)

As in other countries, the traditional doctor-patient relationship in the Japanese healthcare system has often been characterised as being of a paternalistic nature. However, in recent years there has been a gradual shift towards a more participatory-patient model in Japan. With advances in technology, the possibility to use digital technologies to improve patient interactions is growing and is in line with changing attitudes in the medical profession and society within Japan and elsewhere. The implementation of an online patient engagement platform (...) is being considered by the Myotonic Dystrophy Registry of Japan. The aim of this exploratory study was to understand patients’ views and attitudes to using digital tools in patient registries and engagement with medical research in Japan, prior to implementation of the digital platform. We conducted an exploratory, cross-sectional, self-completed questionnaire with a sample of myotonic dystrophy patients attending an Open Day at Osaka University, Japan. Patients were eligible for inclusion if they were 18 years or older, and were diagnosed with MD. A total of 68 patients and family members attended the Open Day and were invited to participate in the survey. Of those, 59 % submitted a completed questionnaire. The survey showed that the majority of patients felt that they were not receiving the information they wanted from their clinicians, which included recent medical research findings and opportunities to participate in clinical trials, and 88 % of patients indicated they would be willing to engage with digital technologies to receive relevant medical information. Patients also expressed an interest in having control over when and how they received this information, as well as being informed of how their data is used and shared with other researchers. Overall, the findings from this study suggest that there is scope to develop a digital platform to engage with patients so that they can receive information about medical care and research opportunities. While this study group is a small, self-selecting population, who suffer from a particular condition, the results suggest that there are interested populations within Japan that would appreciate enhanced communication and interaction with healthcare teams.

This paper examines the methodological claim made famous by P.F. Strawson: that we understand what features are required for responsible agency by exploring our attitudes and practices of holding responsible. What is the presumed metaphysical connection between holding responsible and being fit to be held responsible that makes this claim credible? I propose a non-standard answer to this question, arguing for a view of responsible agency that is neither anti-realist (i.e. purely 'conventionalist') nor straightforwardly realist. It is instead ‘constructivist’. On (...) the ‘Scaffolding View’ I defend, reactive attitudes play an essential role in developing, supporting, and thereby maintaining the capacities that make for responsible agency. While this view has relatively novel implications for a metaphysical understanding of capacities, its chief virtue, in contrast with more standard views, is providing a plausibly defensible account of how so-called responsible agents genuinely deserve to be treated as such.

La mayoría de interpretaciones sobre la noción de comunidad en Hannah Arendt, han pasado por alto el esfuerzo por parte de la autora de deslindarse de lo que ella considera -la tradición de la filosofía política-. Arendt encuentra que dicha tradición ha sido incapaz de reconocer la pluralidad y contingencia propias de los asuntos humanos. Este libro se propone buscar en el pensamiento de la autora una posible noción de Comunidad que conciba la pluralidad como -ley de la tierra-, y (...) vea en la acción esa puesta en escena de dicha pluralidad.

This study explores professional footballers’ perceptions of where banter crosses the conceptual line into bullying. The study’s focus is of importance, given the impact that abusive behaviors have been found to have on the welfare and safeguarding of English professional footballers. A phenomenological approach was adopted, which focused on the essence of the participants’ perceptions and experiences. Guided by Interpretative Phenomenological Analysis, individual semi-structured interviews were conducted with 18 male professional footballers from three Premier League and Championship football clubs. The (...) findings from this study revealed several key superordinate themes in relation to the dividing line between bullying and banter. These themes included “perception,” “intentionality,” “detecting the line,” and “having a bit of banter.” The findings demonstrate how perceptions of bullying and banter are nuanced by individual differences among the players and the culture of the professional football context. Specifically, it was found that the professional football context can legitimize forms of humor blurring the lines between bullying and banter, challenging the typically positive view of the concept of banter in this environment. From an applied perspective, these findings highlight the need for coaches, players, and football clubs more broadly to address cultural expectations around banter in their environment, while educating individuals around their own perceptions of bullying and banter.

In Building Better Beings, Vargas develops and defends a naturalistic account of responsibility, whereby responsible agents must possess a feasibly situated capacity to detect and respond to moral considerations. As a preliminary step, he also offers a substantive account of how we might justify our practices of holding responsible—viz., by appeal to their efficacy in fostering a ‘valuable form of agency’ across the community at large, a form of agency that precisely encompasses sensitivity to moral considerations. But how do these (...) accounts relate to one another? Though I find much that is appealing in Vargas’s general approach, I challenge his insistence that these accounts should be treated as ‘conceptually independent’, arguing that this generates an objectionable “justification gap”: on his analysis, someone could remain an appropriate target of our responsibility practices and yet fail to be a morally responsible agent. In closing, I offer a potential solution to this problem, though it means re-visioning how the account of moral responsibility is conceptually tied to the justification of our responsibility practices.
