Entrenchment and schematisation are the two most important cognitive processes in language acquisition. In this article, the role of the two processes, operationalised by token and type frequency, in the production of overgeneralised verb forms in Croatian preschool children is investigated using a parental questionnaire and computational simulation of language acquisition. The participants of the questionnaire were parents of children aged 3;0–5;11 years (n = 174). The results showed that parents of most children (93 %) reported the parallel use of (...) both adult-like and overgeneralised verb forms, suggesting that Croatian-speaking preschool children have not yet fully acquired the verbal system. The likelihood of overgeneralised forms being reported decreases with the age of the children and verb type frequency. The results of the computational simulation show that patterns with a higher type frequency also show a greater preference for the correct form, while lexical items show both learning and unlearning tendencies during the process.

Approaches to business ethics can be roughly divided into two streams: ‹codes of behavior’ and ‹forms of subjectification’, with code-oriented approaches clearly dominating the field. Through an elaboration of poststructuralist approaches to moral philosophy, this paper questions the emphasis on codes of behaviour and, thus, the conceptions of the moral and responsible subject that are inherent in rule-based approaches. As a consequence of this critique, the concept of a practice-based ‹ethics of responsiveness’ in which ethics is never final but rather (...) always ‹to come’, is investigated. In such an approach the ethical self is understood as being continuously constituted within power/knowledge relations. Following this line, we ask how one can become a responsible subject while also acknowledging certain limits of full responsibility. We thereby explore responsibility as a considered but unconditional openness in response to the other. (shrink)

Bernard Rollin argues that it is permissible to change an animal's telos through genetic engineering, if it doesn't harm the animal's welfare. Recent attempts to undermine his argument rely either on the claim that diminishing certain capacities always harms an animal's welfare or on the claim that it always violates an animal's integrity. I argue that these fail. However, respect for animal dignity provides a defeasible reason not to engineer an animal in a way that inhibits the development of those (...) functions that a member of its species can normally perform, even if the modification would improve the animal's welfare.

Episodic and semantic memory are often taken to be fundamentally different mental systems, and contemporary philosophers often pursue research questions about episodic memory, in particular, in isolation from semantic memory. This paper challenges that assumption, and puts pressure on philosophical approaches to memory that break off episodic memory as its own standalone topic. I present and systematize psychological and neuroscientific theories of semanticization, the thesis that memory content tends to drift from episodic to semantic in structure over time and exposure (...) to an environment. Semanticization, I argue, is a long-term interconnection between episodic and semantic systems that requires approaching both the content and function of these two memory systems as a whole. Thus we have a reason to reject projects by Michael Martin, which aims to carve out a uniquely episodic memory content, and Kourken Michaelian, which pairs episodic memory to its own unique function. Instead, seeing declarative memory as a single system with two facets or even a continuum of features allows for deeper insight into both content and function. (shrink)

Sometimes, we face choices between actions most likely to lead to valuable outcomes, and actions which put us in a better position to learn. These choices exemplify what is called the exploration/exploitation trade-off. In computer science and psychology, this trade-off has fruitfully been applied to modulating the way agents or systems make choices over time. This article extends the trade-off to belief. We can be torn between two ways of believing, one of which is expected to be more accurate in (...) light of current evidence, whereas the other is expected to lead to more learning opportunity and accuracy in the long run. Further, it is sometimes rationally permissible to choose the latter. The article breaks down the features of action which give rise to the trade-off, and then argues that each feature applies equally well to belief. This conclusion is an instance of a systematic, foreseeable way in which what is rational to believe now depends on what one expects to be doing in the future. That is, epistemic rationality fundamentally concerns time. (shrink)

What does it mean to hold a belief? Some of our ways of speaking in English suggest that to hold a belief is to have something in your mind: beliefs are things we acquire, defend, recover, and so on (Abelson, 1986). That is, believing is a matter of being in a state of having a thing. In this paper, I will argue for an alternative: believing is something we do. This is not a new suggestion. For instance, Matthew Boyle (2011) (...) defends a theory of belief as an activity, which he traces back to Aristotle. This paper, however, makes two new contributions: first, I argue for an analogy between belief and planning that fleshes out what it would mean to understand belief as an activity, and second, I aim to show how the resulting view can help sense of a variety of theories in cognitive psychology that suggest cognitive information storage is dynamic and reconstructive.

Mental simulation — such as imagining tilting a glass to figure out the angle at which water would spill — can be a way of coming to know the answer to an internally or externally posed query. Is this form of learning a species of inference or a form of observation? We argue that it is neither: learning through simulation is a genuinely distinct form of learning. On our account, simulation can provide knowledge of the answer to a query even (...) when the basis for that answer is opaque to the learner. Moreover, through repeated simulation, the learner can reduce this opacity, supporting self-training and the acquisition of more accurate models of the world. Simulation is thus an essential part of the story of how creatures like us become effective learners and knowers. (shrink)

The debate on love's reasons ignores unrequited love, which—I argue—can be as genuine and as valuable as reciprocated love. I start by showing that the relationship view of love cannot account for either the reasons or the value of unrequited love. I then present the simple property view, an alternative to the relationship view that is beset with its own problems. In order to solve these problems, I present a more sophisticated version of the property view that integrates ideas from (...) different property theorists in the love literature. However, even this more sophisticated property view falls short in accounting for unrequited love's reasons. In response, I develop a new version of the property view that I call the experiential view. On this view, we love a person not only in virtue of properties shaped by and experienced in a reciprocal loving relationship, but also in virtue of perspectival properties, whose value can be properly assessed also outside of a reciprocal loving relationship. The experiential view is the only view that can account not only for reciprocated love's reasons, but also for unrequited love's reasons. (shrink)

This paper aims to reconfigure the place of memory in epistemology. I start by rethinking the problem that memory systems solve; rather than merely functioning to store information, I argue that the core function of any memory system is to support accurate and relevant retrieval. This way of specifying the function of memory has consequences for which structures and mechanisms make up a memory system. In brief, memory systems are modeling systems. This means that they generate, update and manage a (...) series of overlapping, simplified, relational representations that map out features of the world. Succeeding at building and maintaining models requires the kind of active knowledge generation traditionally associated only with deliberative reasoning. (shrink)

People often answer why-questions with what we call experiential explanations: narratives or stories with temporal structure and concrete details. In contrast, on most theories of the epistemic function of explanation, explanations should be abstractive: structured by general relationships and lacking extraneous details. We suggest that abstractive and experiential explanations differ not only in level of abstraction, but also in structure, and that each form of explanation contributes to the epistemic goals of individual learners and of science. In particular, experiential explanations (...) support mental simulation and survive transitions across background theories; as a result, they support learning and help us translate between competing frameworks. Experiential explanations play an irreducible role in human cognition – and perhaps in science. (shrink)

Obstetric violence – psychological and physical violence by medical staff towards women giving birth – has been described as structural violence, specifically as gender violence. Many women are affected by obstetric violence, with awful consequences. The phenomenon has so far been mainly investigated by the health and social sciences, yet fundamental theoretical and conceptual questions have gone unnoticed. Until now, the phenomenon of obstetric violence has been understood as one impeding autonomy and individual agency and control over the body. In (...) this article I will argue that the phenomenon of obstetric violence occurs in a specific state of embodied vulnerability and that might be destructive for subjectivity since it fails to recognize that state and instead disallows support and demolishes relationships and interdependence. This might introduce a conceptual shift and the phenomenon might be reconceptualized as a moment where vulnerability is misrecognized and ambiguity, relations and support are banned. In this case violence is recognized as cutting the original links to our bodies and the world that constitute our phenomenological condition, instead of as hurting the autonomous subject. Obstetric violence, thus, calls to be reflected upon through de Beauvoir’s ideas on ambiguity, the embodied and situated subject and the subject as essentially construed in relations. I believe that de Beauvoir’s conception of the authentic embodied subject as necessarily ambiguous – immanent and transcendent at the same time and ineludibly linked to the world and its others – will be extremely useful for construing this new understanding of how obstetric violence happens and of what precisely constitutes its damage.

Geometric theories are presented as contraction- and cut-free systems of sequent calculi with mathematical rules following a prescribed rule-scheme that extends the scheme given in Negri and von Plato. Examples include cut-free calculi for Robinson arithmetic and real closed fields. As an immediate consequence of cut elimination, it is shown that if a geometric implication is classically derivable from a geometric theory then it is intuitionistically derivable.

In this article, I argue that many women lack the epistemic resources that would allow them to recognise the practice of vaginal examinations during childbirth as violent or as unnecessary and potentially declinable. I address vaginal examinations during childbirth as a special case of obstetric violence, in which women frequently lack the epistemic resources necessary to recognise the practice as violent not only because of the inherent difficulty of recognising violence that happens in an ‘essentially benevolent’ setting such as the (...) medical one, but also, and mainly, due to the pervasive sexual reification of women under patriarchy and the pervasive shame to which women are subjected. My argument is that the practice of vaginal examinations is indeed experienced – bodily apprehended – as violent by many women, but that full epistemic recognition of this violence is frequently obstructed because the experience perfectly coincides with the normal phenomenological situation of women within patriarchy and thus cannot really be framed as violent. A phenomenological analysis presenting the embodied experience of women under patriarchy as always already essentially tied to sexual availability and commodification, and to shame, will explain this epistemological impairment. A phenomenological take on Judith Butler’s distinction between ‘recognition’ and ‘apprehension’ informs my analysis: I deploy it to provide a richer, more nuanced response to the question of why vaginal examinations are not fully recognised and expressed as violent – even when they are, frequently, apprehended as such. Furthermore, Butler’s ideas about the epistemic ‘framings’ through which we make sense of different kinds of lives (grievable versus ungrievable) will help me to explain how the patriarchal sexual reification of women in fact already frames sexual violence as not-violence – which ultimately also prevents labouring women (and obstetrics staff) from recognising vaginal examinations during labour as violence.

According to the terms of Aristotle's Politics, to be alive is to instantiate an operation of power. This volume addresses the intertwining of power and life in Aristotle's thought, offering a critical re-appraisal of the concepts of life, the animal, and political animality in his political theory.

This paper offers a critical analysis of program evaluation in contemporary urban agriculture. Drawing on data from an exploratory study designed at the request of and in collaboration with urban agriculture practitioners in Massachusetts, it describes both their critiques of extant practices of program evaluation and their visions for alternative ways of telling the story of their work. Related, it explores practitioners’ interest in building capacity for policy advocacy, working collectively to create transformative social change, and, related, establishing new kinds (...) of relationships with state and philanthropic funders. Building on scholarship that has observed that urban agriculture is characterized by an internal contradiction—i.e., its simultaneous orientation to “neoliberal” and “radical” agendas —this analysis calls attention, especially, to the complex role of metrics, which may not only entrench neoliberalism in UA organizations, but also provide a mechanism for challenging its assumptions and advancing the radical project of food justice.

Just as we may ask whether, and under what conditions, a collection of objects composes a single object, we may ask whether, and under what conditions, a collection of actions composes a single action. In the material objects literature, this question is known as the "special composition question," and I take it that there is a similar question to be asked of collections of actions. I will call that question the "special composition question in action," and argue that the correct (...) answer to this question depends on a particular kind of consequence produced by the individual constituent actions.

With the emergence of systems biology the notion of organizing principles is being highlighted as a key research aim. Researchers attempt to ‘reverse engineer’ the functional organization of biological systems using methodologies from mathematics, engineering and computer science while taking advantage of data produced by new experimental techniques. While systems biology is a relatively new approach, the quest for general principles of biological organization dates back to systems theoretic approaches in early and mid-20th century. The aim of this paper is (...) to draw on this historical background in order to increase the understanding of the motivation behind the systems theoretic approach and to clarify different epistemic aims within systems biology. We pinpoint key aspects of earlier approaches that also underlie the current practice. These are i) the focus on relational and system-level properties, ii) the inherent critique of reductionism and fragmentation of knowledge resulting from overspecialization, and iii) the insight that the ideal of formulating abstract organizing principles is complementary to, rather than conflicting with, the aim of formulating detailed explanations of biological mechanisms. We argue that looking back not only helps us understand the current practice but also points to possible future directions for systems biology. (shrink)

When entering an environment, animals – including humans – tend to consult their memories to determine what they know about the place. This information is useful to determine: is this place safe? And what happens next? In this chapter, we argue on both empirical and conceptual grounds that memory is largely organized by space. Spatial relations determine what is recalled and which experiences are combined in generalizations. Time does not play an analogous role. We show that space and time in (...) memory are thus deeply asymmetrical. We conclude with a consequence of our view: spatial organization entails a basic form of abstraction in a way temporal organization does not, and so the spatial organization of memory reveals that memory involves generalization from the very beginning.

This far-ranging collection of essays represents a conference of the same name held at Emory University in conjunction with a meeting of the “Rethinking Plato’s Parmenides” seminar sponsored by the Society of Biblical Literature.In embracing authors as diverse as Plato himself, Epictetus, Ralph Cudworth, Yeats, and Levinas, to name a few of the Platonists identified herein, the volume clearly and deliberately stretches the meaning of this rubric to its outer limits. This review will reprise some of the articles from each (...) of the book’s sections—Ancient, Late Antique, Renaissance and Modern, and Post-modern Platonisms—in an effort to help readers gauge the argument of the book, which may or may not be endorsed by each of the individual contributors.

This paper aims to understand how we reason from historical premises to normative conclusions, tracing this question through the work of Muhammad Iqbal. On our reading, he wavers between two views of history, one a kind of natural science, and the other akin to religious interpretation. These tell different stories about the lessons we draw from history.

Formal representations drawn from rational choice theory have been used in a variety of ways to fruitfully model the way in which actual agents are approximately rational. This analysis requires bridging between ideal normative theory, in which the mechanisms, representations, and other such internal parts are in an important sense interchangeable, and descriptive psychological theory, in which understanding the internal workings of the agent is often the main goal of the entire inquiry. In this paper, I raise a problem brought (...) on by this gap: for almost every theory of approximate rationality, there will be an empirically indistinguishable alternative that individuates the parts of the agent in a significantly different way.

Though Arthur Prior is now best known for his founding of modern temporal logic and hybrid logic, much of his early philosophical career was devoted to history of logic and historical logic. This interest laid the foundations for both of his ground-breaking innovations in the 1950s and 1960s. Because of the important rôle played by Prior's research in ancient and medieval logic in his development of temporal and hybrid logic, any student of Prior, temporal logic, or hybrid logic should be (...) familiar with the medieval logicians and their work. In this article we give an overview of Prior's work in ancient and medieval logic. (shrink)

We argue that Kraay's "theistic multiverse" response to the objections to theism [Kraay 2011] is unsuccessful as it simply shifts the problems leveled against theism from the level of possible worlds to the level of possible universes. Furthermore, when we restate the objections at the level of possible universes, we can show how Kraay's conclusion about the uniqueness of the theistic multiverse is undermined.

In lieu of an abstract, here is a brief excerpt of the content:Whiteness and the General WillDiversity Work as Willful WorkSara AhmedIn this essay I explore whiteness in relation to the general will. My starting point is that the idea of “the general will” offers us a vocabulary for thinking through the materiality of race. In his keynote address to the 40th Annual Philosophy Symposium in 2010, Charles Mills argues that race is material: it becomes part of the living human (...) body. Mills draws on recent theories of whiteness as habit, including the work of Linda Alcoff (2006) and Shannon Sullivan (2006). Quoting from Sullivan, he suggests that whiteness is in “the nose that smells, the back, neck and other muscles that imperceptibly tighten with anxiety, and the eyes that see some but not all physical differences as significant” (Sullivan 2006, 188). Whiteness is embodied; it is in bodily matter as well as affecting how bodies matter. Mills then suggests that the materiality of whiteness is its “resistance to will.” One definition of materiality could be this: resistance to will.This essay takes up the theme of the materiality of race by thinking of whiteness in relation to the will. There are clearly risks in such an undertaking: after all, the idea of whiteness as willed might seem to imply that whiteness is volitional: and can be simply “willed away.”1 I want to suggest that if whiteness is resistant to will, as that which cannot be simply willed away, then whiteness can also be understood as willed: in other words, what cannot be willed away is a willing way. Edward Said’s definition of Orientalism as “willed human work,” which as a definition has yet to be rigorously understood, could be considered an important precedent to my argument (1978, 140). The suggestion is not [End Page 1] simply that the Orient is brought into existence, or made to exist over time, but that the very labor of creating the Orient, the land of the stranger, the land far away, is what establishes a direction. Once the Orient has come to exist, there is a willing of its existence; to keep going that way is to keep that way going. Willed work is work that in willing that way creates a way that can be willed. It is not as the old English cliché says—where there’s a will there’s a way—but rather to will is to way. I think it is useful to think of whiteness in this way, as a willing way, which is of course only one way of thinking about whiteness.I pose the generality of the will as a way of reflecting on “institutional whiteness.” Whiteness becomes “the material” of an institutional body, whether that body is the nation, an organization, a neighborhood, or a street. We can consider an institution as a body with parts: it too has noses, mouths, muscles that register anxiety, as well as ears and eyes. Just think of how Neighborhood Watch, as a national or even global technology, uses the injunction that citizens should become the “eyes and ears of the police.” A good citizen is the one who accepts this injunction: the one who is willing to watch out for strangers, those who are loitering, who seem suspicious, or out of place. Institutions have “detection systems”: they have parts that register the approach of strangers. A collective body in registering those who are out of place, both creates strangers and establishes a direction toward them, as those who threaten the place of the “in place,” as those who generate anxiety.A key event in my own life was of becoming a stranger in a white neighborhood in Adelaide, Australia, in a place I called home. I was fourteen years old. I was stopped by two policemen in a car who asked me, “Are you Aboriginal?” It turned out that there had been some burglaries in the area. It was an extremely hostile address, and it was an unsettling experience at the time. It was an experience of being made into a stranger, the one who is recognized as “out of place,” as the one who does not belong, whose proximity is registered... (shrink)

Some religious requirements seem genuinely arbitrary in the sense that there seem to be no sufficient explanation of why those requirements with those contents should pertain.

We lay out four accounts of what such arbitrariness could consist in, and show how each account provides a (...) different sort of baseline for understanding how obedience to arbitrary requirements could, in principle, be rational.

Revered as the ‘Queen of Qawwali’ and ‘Queen of Sufi music’, sixty-seven-year-old Abida Parveen is a spiritual phenomenon who transcends gender while performing. She is known for her signature fashion style of buttoned-up masculine-cut kurta with matching shalwar and an ajrak shawl. Her aesthetic circulates within transnational and national fashion media and popular cultural spaces through descriptors such as androgynous, masculine, modest, indigenous and sacred. As a highly respected figure with widely circulating performances on both the national and international stages, (...) as well through multiple media circuits, including television, social/digital media and broadcast concerts, Parveen's undeniable fame and her transgressive entry into an otherwise male-dominated music genre raises important questions about gender, embodiment, spirituality and the sacred. In analysing Parveen's body and dress in performance, I centre her sartorial style as sites of spirituality and affect to ask: what does it mean for Parveen to transcend gender through a performance of androgynous Sufism and mobilise it as an entry way into spiritual iconism? What imaginations around spirituality and the sacred become available through Parveen's sartorial practices? How does Parveen's style offer an alternative route to Muslim spirituality? Taking up Parveen's embodied coagulation between fashion and the sacred reveals an absence in feminist fashion studies on which subjects and styles are viewed as important, relevant, resistant or transgressive and thus worthy of theorisation. As a feminist scholar interested in the relationship between gender, power and self/representation, I see Parveen as a key global cultural and spiritual figure who necessitates transnational feminist analysis. This article is situated at the intersections of fashion and cultural studies, feminist, queer and trans spiritualities and South Asia studies. (shrink)

One of the most important concepts in Simone de Beauvoir’s existentialist and phenomenological ethics is the concept of freedom. In this article, I would like to argue that Beauvoir’s concept of freedom is problematic in being strongly constrained by its essentially active character. This constraint contradicts some of Beauvoir’s major ideas, such as the one that considers the body as a situation, as a source of activity and of freedom in itself, as well as the idea of eroticism as one (...) of the most important expressions of authenticity. I will show that Beauvoir’s concept of freedom can appear to be less constrained by the necessity to be inherently active if we look at it through the ‘crack’ provided by her conception of the erotic body as already embodying freedom. Using this ‘crack’, I will attempt to shed new light on the aspects of Beauvoir’s idea of the erotic that are productive for her conceptions of ethics and of freedom. (shrink)

Specifically, it considers how scientists, risk assessors, and regulators have used genetically modified mouse models to translate across scientific disciplines, articulate emergent molecular forms, standards, and practices with the extant? gold standard,? and establish roles for molecular knowledge in risk assessment and regulation. Noting variation both within and between regulatory agencies in responses to data from these models, the article (...) describes also the role of public-private networks and their effects on professional and institutional imperatives which shape regulators? responses to the potential applications of these models. The conclusions address the importance of translation for understanding the wider implications of the molecularization of environmental health science. (shrink)

Philosophical writing is challenging for students new to philosophy. Many philosophy classes are populated, for the most part, by students who have never taken philosophy before. While many institutions offer general writing support services, these services tend to be most beneficial for helping to identify problems with style and grammar. They are not equipped to help students with the particular challenges that come with writing philosophy for the first time. We implemented the “Home Base” Mentoring Program in two introductory level (...) philosophy courses to target the specific challenges that novice learners have when learning how to write philosophy. Through the program, students had access to writing mentors who were undergraduate senior philosophy majors. Based on surveys given to the students who have participated in this program, we found that the program boosted student confidence in writing and also worked to develop a welcoming, judgment-free, and encouraging environment in the philosophy department more generally.

Memory structures range across the dimensions that distinguish language-like thought. Recent work suggests agent- or situation-specific information is embedded in these structures. Understanding why this is, and pulling these structures apart, requires observing what happens under major changes. The evidence presented for the language-of-thought (LoT) does not look broadly enough across time to capture the function of representational structure.

In June 2016, Qandeel Baloch, a 26-year-old Pakistani social media star, was murdered. Her death sparked both public outrage and a policy debate around ‘honour killing’, digital rights and sex-positive sexuality across Pakistan and its diasporas. Qandeel challenged what constitutes a proper Pakistani woman, an authentic Baloch and a respectable digital citizen. As a national sex symbol, she failed at the gendered workings of respectable heterosexuality, and during her short lifetime she optimised this failure and public fetish as a technologically (...) mediated social currency (clicks, hashtags, comments, likes, reposts) to build a transnational celebrity brand. I centre Qandeel Baloch’s life and afterlives to think through the economic entanglements of honour, racialised ethnicity, coloniality, sexual violence and social media at the intersections of globalised anti-Blackness and honourable brownness as a matter of global capital. Within these complex registers of coloniality, Qandeel’s life and brutal murder necessitate a rethinking of categories of racialised ethnicity (Baloch), sexual labour (racial capital) and social media (digitality) as vectors of value for capitalism and nationalism. By centring Qandeel, I define honour as a form of racialised property relations. This rereading of honour, as an economic metric of heteropatriarchy, shifts my lens of honour killing from a crime of culture to a crime of property. Women’s honour functions as a necrocapitalist technology that constructs female and feminine bodies as the debris of heterosexual empire through racialised, gendered and sexualised property relations. These relations and registers of honour get further complicated by social media currency and discussions around digital rights, privacy and freedom of expression. Honour is, therefore, the economic management of sexual morality produced through race, religion and imperialism. (shrink)

Background:Smart Aging is a serious game (SG) platform that generates a 3D virtual reality environment in which users perform a set of screening tasks designed to allow evaluation of global cognition. Each task replicates activities of daily living performed in a familiar environment. The main goal of the present study was to ascertain whether Smart Aging could differentiate between different types and levels of cognitive impairment in patients with neurodegenerative disease.Methods:Ninety-one subjects (mean age = 70.29 ± 7.70 years)—healthy older adults (...) (HCs,n= 23), patients with single-domain amnesic mild cognitive impairment (aMCI,n= 23), patients with single-domain executive Parkinson's disease MCI (PD-MCI,n= 20), and patients with mild Alzheimer's disease (mild AD,n= 25)—were enrolled in the study. All participants underwent cognitive evaluations performed using both traditional neuropsychological assessment tools, including the Mini-Mental State Examination (MMSE), Montreal Overall Cognitive Assessment (MoCA), and the Smart Aging platform. We analyzed global scores on Smart Aging indices (i.e., accuracy, time, distance) as well as the Smart Aging total score, looking for differences between the four groups.Results:The findings revealed significant between-group differences in all the Smart Aging indices: accuracy (p< 0.001), time (p< 0.001), distance (p< 0.001), and total Smart Aging score (p< 0.001). The HCs outperformed the mild AD, aMCI, and PD-MCI patients in terms of accuracy, time, distance, and Smart Aging total score. In addition, the mild AD group was outperformed both by the HCs and by the aMCI and PD-MCI patients on accuracy and distance. No significant differences were found between aMCI and PD-MCI patients. Finally, the Smart Aging scores significantly correlated with the results of the neuropsychological assessments used.Conclusion:These findings, although preliminary due to the small sample size, suggest the validity of Smart Aging as a screening tool for the detection of cognitive impairment in patients with neurodegenerative diseases.

Achieving a good clinical trial design increases the likelihood that a trial will take place as planned, including that data will be obtained from a sufficient number of participants, and the total number of participants will be the minimal required to gain the knowledge sought. A good trial design also increases the likelihood that the knowledge sought by the experiment will be forthcoming. Achieving such a design is more than good sense—it is ethically required in experiments when participants are at (...) risk of harm. This paper argues that doing a power analysis effectively contributes to ensuring that a trial design is good. The ethical importance of good trial design has long been recognized for trials in which there is risk of serious harm to participants. However, whether the quality of a trial design, when the risk to participants is only minimal, is an ethical issue is rarely discussed. This paper argues that even in cases when the risk is minimal, the quality of the trial design is an ethical issue, and that this is reflected in the emphasis the Belmont Report places on the importance of the benefit of knowledge gained by society. The paper also argues that good trial design is required for true informed consent. (shrink)

Temporal logic as a modern discipline is separate from classical logic; it is seen as an addition or expansion of the more basic propositional and predicate logics. This approach is in contrast with logic in the Middle Ages, which was primarily intended as a tool for the analysis of natural language. Because all natural language sentences have tensed verbs, medieval logic is inherently a temporal logic. This fact is most clearly exemplified in medieval theories of supposition. As a case study, (...) we look at the supposition theory of Lambert of Lagny, extracting from it a temporal logic and providing a formalization of that logic. (shrink)

A sense of belonging is an integral feature of an online community of learners. This article explores the ways in which digital technologies in an online teacher education programme can facilitate social presence and in turn nurture a sense of belonging in an OCL. A sense of belonging can lower attrition rates in distance programmes that attract learners who are marginalised from on campus education. This can help address issues of social justice by supporting equitable access and participation in higher (...) education. Findings from a qualitative case study indicate the power that digital technologies can have in facilitating social presence and a sense of belonging in an OCL. This study identifies the importance of several factors in this. Firstly, the importance of pedagogical understandings that digital technologies have different affordances in nurturing an OCL, and secondly, that each participant had a different perspective on the affordances of each digital technology in their usefulness for fostering social presence and a sense of belonging.
