To acquire one’s native phonological system, language-specific phonological categories and relationships must be extracted from the input. The acquisition of the categories and relationships has each in its own right been the focus of intense research. However, it is remarkable that research on the acquisition of categories and the relations between them has proceeded, for the most part, independently of one another. We argue that this has led to the implicit view that phonological acquisition is a “two-stage” process: Phonetic categories (...) are first acquired and then subsequently mapped onto abstract phoneme categories. We present simulations that suggest two problems with this view: First, the learner might mistake the phoneme-level categories for phonetic-level categories and thus be unable to learn the relationships between phonetic-level categories; on the other hand, the learner might construct inaccurate phonetic-level representations that prevent it from finding regular relations among them. We suggest an alternative conception of the phonological acquisition problem that sidesteps this apparent inevitability and acquires phonemic categories in a single stage. Using acoustic data from Inuktitut, we show that this model reliably converges on a set of phoneme-level categories and phonetic-level relations among subcategories, without making use of a lexicon.

In order to apply known general theorems about the effective properties of recursive structures in a particular recursive structure, it is necessary to verify that certain decidability conditions are satisfied. This requires the determination of when certain relations, called back and forth relations, hold between finite strings of elements from the structure. Here we determine this for recursive reduced abelian p-groups, thus enabling us to apply these theorems.

This commentary briefly reviews the challenges associated with the concept of cyber deterrence. It considers the concept of deterrence more broadly before identifying the specific issues that make both deterrence by denial and by punishment particularly difficult in cyberspace. However, overall, it argues that the concept is valid and indeed essential in contributing to delivering strategic stability.

Our thesis is that there is no moral requirement to refrain from emitting reasonable amounts of greenhouse gases solely in order to enjoy oneself. Joyriding in a gas guzzler provides our paradigm example. We first distinguish this claim that there is no moral requirement to refrain from joyguzzling from other more radical claims. We then review several different proposed objections to our view. These include: the claim that joyguzzling exemplifies a vice, causes or contributes to harm, has negative expected value, (...) exceeds our fair share of global emissions, and undermines political duties. We show why none of these objections succeeds and conclude that no good reason has yet been proposed that shows why joyguzzling violates a moral requirement. (shrink)

We begin by setting out the posision dubbed 'Fregean descriptivism', that Kripke attributed to Frege. We then set out various descriptivist theses. We proced to argue that Kripke’s interpretation of Frege as a reference-fixing descriptivist stems from his ascription of two other views, each logically weaker than reference-fixing descriptivism itself, to Frege. These are sense descriptivism and the view that sense fixes reference. The meaning descriptivism and the reference-fixing descriptivism of Kripke’s Frege have sense descriptivism as their common, logically weaker, (...) core. Since we do not concur with Kripke’s view that Frege was a sense descriptivist, we do not share his reasons for thinking that Frege was a reference-fixing descriptivist. (shrink)

For as long as history has been with us, religion has been a feature of human life. There is no known culture for which we have an ethnographic or an archaeological record that does not have some form of religion. Even in the secular societies that have become more common in the past few centuries, there are people who consider themselves religious and aspire to practise the rituals of their religion. These religions vary in form, style and size from small (...) cults numbering a few hundred people centred around a charismatic leader to worldwide organizations numbering tens, or even hundreds, of millions of adherents with representations in every country. Some, like Buddhism, take an individualistic stance (your salvation is entirely in your own hands), some like the older Abrahamic religions view salvation as more of a collective activity through the performance of appropriate rituals, and a few (Judaism is one) have no formal concept of an afterlife. Some like Christianity and Islam believe in a single all- powerful God. (shrink)

This book engages Christian love theologies, feminist economics, and political theory to identify elements of a Christian ethic of dependent care relations.

Protestant Christian ethicist Timothy Jackson and secular feminist philosopher Eva Feder Kittay each explore the relationship between love or care and justice through the lens of human dependency. Jackson sharply prioritizes agape over justice, whereas Kittay articulates a more complex and integrated understanding of the relationship of care and distributive justice. An account of Christian love and its relation to justice must account for the gratuity, mutuality, and reciprocity that pervade human existence. Such an account must integrate provision for another's (...) basic needs, a feature of agape, with a distributive justice that fairly allocates the material prerequisites of care and the burden of caring labor. Kittay's treatment of care and justice is more adequate to the realities of human embodiment and the social organization of care than Jackson's, but neither offers a fully adequate ground for the moral personhood of all human beings, including deeply dependent persons.

THE RECENT CONVERSATION WITHIN CHRISTIAN ETHICS ABOUT THE RELAtionship between universal obligations and particular, intensive relations—between agape and "special relations"—largely accepts Gene Outka's formulation that these are separate and competing moral claims that must be balanced within the Christian moral life. I examine the relationship between agape and special relations through the lens of dependency and dependent-care relations. Attention to dependent care and the material needs addressed within them raises questions about the sharp division between universal and particular obligations. Drawing (...) on the work of feminist philosopher Eva Feder Kittay, I argue that an adequate understanding of Christian love must take account of both our fundamental human equality and the pervasiveness of dependency in human life. Such an understanding of Christian love reveals that agape is a matter of personal and social ethics. (shrink)

Many suggest that we should look backward and measure the differences among various parties' past emissions of greenhouse gases to allocate moral responsibility to remedy climate change. Such backward-looking approaches face two key objections: that previous emitters were unaware of the consequences of their actions, and that the emitters who should be held responsible have disappeared. I assess several arguments that try to counter these objections: the argument from strict liability, arguments that the beneficiary of harmful or unjust emissions should (...) pay, and arguments from distributive justice. I argue that none of these successfully justify a backward-looking approach to the temporally remote portion of the climate burden. (shrink)

Since World War II, US Catholic anti-abortion discourse has been framed in term of rights-language, ascribing civil and human rights to the prenate from the moment of conception. Yet many of those who would criminalize abortion have allied with anti-democratic political movements that buttress White supremacy and threaten civil rights. This contradiction exposes the theoretical inadequacy and epistemological hubris of current Catholic abortion discourse. While the Catholic Church and individual Catholics may subscribe to absolute moral norms against abortion, they should (...) not leverage rights-language to legislate such norms in a pluralistic democracy. Instead, Catholics should draw on our rich tradition of virtuous practical reasoning for an abortion ethic that honors the moral agency of pregnant persons and democratic citizens. (shrink)

The number of International Baccalaureate Diploma Programme (IBDP) schools has increased rapidly in China in recent years. However, access to schools offering the IBDP remains restricted to a relatively elite minority of China’s population due to enrolment barriers for Chinese nationals and relatively high school fees. An implication is that students potentially remain in physical, cultural and socio-economic isolation from host communities. Within this context, this study explored how, and the extent to which, two core components of the IBDP – (...) namely, the Learner Profile and Creativity, Action, Service – help foster inter-cultural understanding between students and other communities within Chinese society. To this end, in mid 2013 interview data were gathered from IBDP teachers, IBDP administrators, and IBDP students from five elite IBDP schools in Beijing and Shanghai. Findings revealed a perception that the Learner Profile could provide a strong theoretical appreciation of the norms and values of other cultures, while Creativity, Action, Service could break down physical divides by offering students an opportunity to interact with people of different cultures and socio-economic groups. Nevertheless, interviewees also noted tensions with the implementation of these components in the context of results-oriented elite IBDP schools in China. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Erotic Attunement: Parenthood and the Ethics of Sensuality between Unequals by Cristina L. H. TrainaSandra Sullivan-DunbarErotic Attunement: Parenthood and the Ethics of Sensuality between Unequals CRISTINA L. H. TRAINA Chicago: University of Chicago Press, 2011, 363 pp. $55.00In this ambitious and broadly interdisciplinary work, Cristina Traina begins from an experience that evades contemporary discussion: maternal sensual pleasure in the care of infants and young children. As Traina notes, (...) this experience puts two contemporary dogmas on a “collision course”: the widely accepted norm that sexual pleasure is intrinsically good and the widely accepted norm that sexual pleasure between unequals is intrinsically exploitative. As with other feminist turns toward neglected experience, this one calls for a recalibration of ethical models—in this case, a more complex and nuanced sexual ethic.Traina challenges readers to broaden notions of sexuality beyond androcentric models focused primarily on particular acts and on genital release. Such models are deeply graven in the Christian tradition and reinforced through reductive cultural appropriations of Freudian thought. But all human relations are embodied and involve desire, argues Traina, and are thus in some sense erotic, though most do not involve genital sexuality. Likewise, her readers are challenged to recognize the pervasiveness of relations of inequality in human life, when most Christian sexual ethics limit themselves to relations between equals, or at least understand a sexual ethic to aim at equality and mutuality.The book engages psychological resources demonstrating the human need for appropriate touch as well as the profound damage done by abusive touch. The need is so universal and foundational that Traina casts it as a human right; yet offering such touch appropriately is a subtle and challenging moral task beset with danger and the potential for self-deception.Traina diagnoses the sexual abuser as a fragmented self, one unable to perceive the concrete reality, needs, and experiences of her victim and bent on the doomed project of creating a whole self by appropriating and objectifying the other. Thus, at the heart of her ethic of sensuality between unequals is the notion of “attunement.” The attuned caregiver can acknowledge and fully experience inclinations, joys, and pains with a contemplative and compassionate awareness that allows considered and appropriate responses. The attuned care-giver lives with “unending, acknowledged desire” (177), a desire that glories in the goodness of the child in her care and, in so doing, creatively elicits subjectivity from her rather than manipulating her to meet the needs of the caregiver. [End Page 240]This ethical vision is developed in dialogue with a number of resources from Christian and secular sources. Traina helpfully nuances a Thomistic account of the virtue of temperance as a guideline for appropriate touch. She also develops revisionist accounts of Augustinian desire offered by Wendy Farley and Linda Holler. I found myself wondering whether some more traditional interpretations of Augustine might serve Traina’s project as well as or better than these revisionist understandings, which emphasize desire as a permanent state rather than directed toward final rest in God.Likewise, Traina works her way through the plethora of recent eros theologies, drawing in particular on recent interpretations of Plato’s Symposium that stress the creativity of eros in bringing to birth goodness and beauty as well as its potential for enabling a degree of other-regard. It seems to this reader that a contemporary ethic of sexuality between unequals calls for greater other-regard than the most generous interpretation of Plato’s ladder of love can suggest. However, Plato’s caution about the profound difficulty of directing eros toward the true good resonates with the difficulty of achieving the “erotic attunement” described by Traina.In any case, quibbles about the resources and interpretations that Traina mines to support her ethic do not lessen the originality, power, and importance of this book, which extends beyond sexual ethics to reframe questions about embodiment, (in)equality, and moral agency in profound and necessary ways.Sandra Sullivan-DunbarLoyola University, ChicagoCopyright © 2014 Society of Christian Ethics...

Many people argue that we should practice conscientious consumption. Faced with goods from gravely flawed production processes, such as wood from clear-cut rainforests or electronics containing conflict minerals, they argue that we should enact personal policies to routinely shun tainted goods and select pure goods. However, consumers typically should be relatively uncertain about which flaws in global supply chains are grave and the connection of purchases to those grave flaws. The threat of significant uncertainty makes conscientious consumption appear to be (...) no better, or even worse, than an overlooked option. This overlooked option is consumption with relinquishment: disregarding each product’s possible connections with upstream grave flaws and using the time, money, and energy saved in this way to address grave flaws directly.

Dale Jamieson has claimed that conventional human-directed ethical concepts are an inadequate means for accurately understanding our duty to respond to climate change. Furthermore, he suggests that a responsibility to respect nature can instead provide the appropriate framework with which to understand such a duty. Stephen Gardiner has responded by claiming that climate change is a clear case of ethical responsibility, but the failure of institutions to respond to it creates a (not unprecedented) political problem. In assessing the debate between (...) Gardiner and Jamieson, I develop an analysis which shows a three-part structure to the problem of climate change, in which the problem Gardiner identifies is only one of three sub-problems of climate change. This analysis highlights difficulties with Jamieson’s argument that the duty of respect for nature is necessary for a full understanding of climate ethics, and suggests how a human-directed approach based on the three-part analysis can avoid Jamieson’s charge of inadequacy.

In my target article, I argued (1) that the relationship between neocortical size and group size in primates implies that there is a cognitive limit on the size of human groups, and (2) that time constraints forced the evolution of language as a more efficient means of bonding the large groups that humans evolved. The doubts about these claims raised by these additional commentaries largely reflect misinterpretation of my original claims.

This paper examines social network size in contemporary Western society based on the exchange of Christmas cards. Maximum network size averaged 153.5 individuals, with a mean network size of 124.9 for those individuals explicitly contacted; these values are remarkably close to the group size of 150 predicted for humans on the basis of the size of their neocortex. Age, household type, and the relationship to the individual influence network structure, although the proportion of kin remained relatively constant at around 21%. (...) Frequency of contact between network members was primarily determined by two classes of variable: passive factors (distance, work colleague, overseas) and active factors (emotional closeness, genetic relatedness). Controlling for the influence of passive factors on contact rates allowed the hierarchical structure of human social groups to be delimited. These findings suggest that there may be cognitive constraints on network size. (shrink)

The purpose of the two studies reported here was to develop an integrated model of the scientific reasoning process. Subjects were placed in a simulated scientific discovery context by first teaching them how to use an electronic device and then asking them to discover how a hitherto unencountered function worked. To do this task, subjects had to formulate hypotheses based on their prior knowledge, conduct experiments, and evaluate the results of their experiments. In the first study, using 20 adult subjects, (...) we identified two main strategies that subjects used to generate new hypotheses. One strategy was to search memory and the other was to generalize from the results of previous experiments. We described the former group as searching an hypothesis space, and the latter as searching an experiment space. In a second study, with 10 adults, we investigated how subjects search the hypothesis space by instructing them to state all the hypotheses that they could think of prior to conducting any experiments. Following this phase, subjects were then allowed to conduct experiments. Subjects who could not think of the correct rule in the hypothesis generation phase discovered the correct rule only by generalizing from the results of experiments in the experimental phase.Both studies provide support for the view that scientific reasoning can be characterized as search in two problem spaces. By extending Simon and Lea's (1974) Generalized Rule Inducer, we present a general model of Scientific Discovery as Dual Search (SDDS) that shows how search in two problem spaces (an hypothesis space and an experiment space) shapes hypothesis generation, experimental design, and the evaluation of hypotheses. The model also shows how these processes interact with each other. Finally, we interpret earlier findings about the psychology of scientific reasoning in terms of the SDDS model. (shrink)

Deep decarbonization – slashing global greenhouse gas emissions to net-zero – now dominates global climate policy. Two recent books assess feasible routes to achieve deep decarbonization. Bill Gates’ How to Avoid a Climate Disaster explains in depth why deep decarbonization requires significant innovations in tech, and Danny Cullenward and David Victor’s Making Climate Policy Work emphasizes the importance of policy innovation (beyond carbon pricing) for driving clean tech breakthroughs. In this critical review essay, I summarize and assess both books. In (...) the final section, I raise several normative questions, which the pair of books might lead us to. (shrink)

Dasein is an entity that can be understood as being-in-the-world, in which the "world" refers to the referential context of meanings. In this context are the environments where the human being as historically constituted relates to other entities, among them the entity called "book" which can mean more than a mere instrument in its instrumentality (Zuhandenheit), but be this entity "the book of my childhood", "of adolescence", etc., unveiling his deliverance in the "for what it is read". The book speaks (...) because the one who wrote it, the Dasein-author, is possessed of language just as the Dasein-reader who relates to the work. Calvin states that the book, as an author’s self-portrait, presents a written world, whose source is the unwritten world, that is, the reality that is more surprising and frightening than what is in the book. The relationship of literature with the philosophy that once belonged to opponents has changed with the writers' attempt to reconcile both movements, including one more element in a triple relationship - Science - Philosophy - Literature. Like the human being, the book has undergone significant changes, such as the rise of digital books. The purpose of the article is to understand these aspects and philosophically interpret some excerpts from world-known works. (shrink)

In this case analysis deception or lying to a dying patient is discussed within the context of different relationships: the relationship between the patient and her family doctor, the relationship between the patient and the surgeon and the relationship between the patient and her family. It is suggested that the principle of veracity is not only a core feature in the patient-doctor relationship but is also fundamentally connected with the basic element of trust between the patient and doctor. The surgeon, (...) in deceiving the patient, even at the request of her husband, betrayed her trust in violating the principle of veracity. The primary responsibility of the surgeon was towards his patient rather than her family. In lying to his patient the surgeon failed to give Mrs Fasper something she needed most: respect for her as a person. (shrink)

Methodological triangulation is the use of more than one method to investigate a phenomenon. Nurse researchers investigate health phenomena using methods drawn from the natural and social sciences. The methodological debate concerns the possibility of confirming a single theory with different kinds of methods. The nursing debate parallels the philosophical debate about how the natural and social sciences are related. This article critiques the presuppositions of the nursing debate and suggests alternatives. The consequence is a view of triangulation that permits (...) different methods to confirm a single theory. The article then explores the consequences for the philosophy of social sciences. (shrink)

Pinter’s play The Caretaker explores interpersonal tensions relating to terminal illness. This paper interrogates notions of care, suffering, ownership, dignity and the consequences of active intervention and inaction in two key sections of the play: Aston’s monologue concerning his own brutal treatment (active intervention) and Davies’s final rejection by the brothers who fail to provide accommodation and care (inaction). This interprofessional analysis combines theatrical and clinical perspectives to create insights which can enhance empathy improve decision-making in end of life care (...) and can inform the education of healthcare professionals.
