Distributional Models of Category Concepts Based on Names of Category Members

Cognitive scientists have long used distributional semantic representations of categories. The predominant approach uses distributional representations of category-denoting nouns, such as “city” for the category city. We propose a novel scheme that represents categories as prototypes over representations of names of its members, such as “Barcelona,” “Mumbai,” and “Wuhan” for the category city. This name-based representation empirically outperforms the noun-based representation on two experiments (modeling human judgments of category relatedness and predicting category membership) with particular improvements for ambiguous nouns. We discuss the model complexity of both classes of models and argue that the name-based model has superior explanatory potential with regard to concept acquisition.     

Expressivism,meaning, and all that

Abstract

It has recently been suggested that meta-normative expressivism is best seen as a meta-semantic, rather than a semantic view. One strong motivation for this is that expressivism becomes, thereby, compatible with truth-conditional semantics. While this approach is promising, however, many of its details are still unexplored. One issue that still needs to be explored in particular, is what accounts of propositional contents are open to meta-semantic expressivists. This paper makes progress on this issue by developing an expressivist-friendly deflationary account of such contents.     

An Analysis of Factors Influencing the International Migration of Indian Nurses

Based on our survey conducted in Tamil Nadu, this paper analyses the characteristics of Indian migrant nurses and the factors influencing their migration. India is considered the second largest exporter of nurses after the Philippines. Many Indian nurses have migrated to work in OECD countries, the Gulf countries and some ASEAN countries. While Indian nurses are migrating overseas to fill shortages at their destinations, India has itself been suffering from an acute scarcity of nurses since its independence in 1947. Therefore, the large scale of nurse migration is a serious threat to the Indian healthcare system. The results of the survey imply that international migration by nurses can be explained in part by the gap between the private sector and the public sector in terms of salary and working environment. Since the impact of social status on the migration decisions of nurses has lessened, economic factors are the crucial determinant of international migration of nurses. Policy intervention in this area is the necessary first step to solving this long-standing problem. The priority in any policies formulated should be given to nurses working in the private sector whose salaries are considerably lower than those in the public sector and whose voices are unheard.     

A Survey of Expectations About the Role of Robots in Robot-Assisted Therapy for Children with ASD: Ethical Acceptability,Trust, Sociability,Appearance, and Attachment

The use of robots in therapy for children with autism spectrum disorder (ASD) raises issues concerning the ethical and social acceptability of this technology and, more generally, about human–robot interaction. However, usually philosophical papers on the ethics of human–robot-interaction do not take into account stakeholders’ views; yet it is important to involve stakeholders in order to render the research responsive to concerns within the autism and autism therapy community. To support responsible research and innovation in this field, this paper identifies a range of ethical, social and therapeutic concerns, and presents and discusses the results of an exploratory survey that investigated these issues and explored stakeholders’ expectations about this kind of therapy. We conclude that although in general stakeholders approve of using robots in therapy for children with ASD, it is wise to avoid replacing therapists by robots and to develop and use robots that have what we call supervised autonomy. This is likely to create more trust among stakeholders and improve the quality of the therapy. Moreover, our research suggests that issues concerning the appearance of the robot need to be adequately dealt with by the researchers and therapists. For instance, our survey suggests that zoomorphic robots may be less problematic than robots that look too much like humans.     

Conversion and the Family: Chinese Hare Krishnas

The multi-cultural and multi-religious context of the globalised world often results in unlikely interactions between the triad of people, cultures, and religion. The result may be that people embrace divergent systems of beliefs. This article explores the dynamics of such interaction within the private domain of the family, when ethnic Chinese adopt an alien faith, that of the Hare Krishna. Four typologies of interactions between convert and family members are proposed, ranging from the most volatile to the most harmonious. These are categorised as contentious, neutral, accommodative, and supportive. The combinations of factors that lead to each type of interaction, such as family–convert relationship, religious identity of family member, residence of the convert, family members’ perception of the Hare Krishna, and the extent of external practices adopted by the converts, are discussed. In particular, qualitative comparative analysis is applied to investigate how these variables combine to lead to each typology.     

Body images of patients with anorexia nervosa, bulimia nervosa and female control subjects: a comparison with male ideals of female attractiveness

Body images of female patients with anorexia nervosa and bulimia nervosa were assessed against females without eating disorders and compared with male ideals of female attractiveness. A computer program was applied to examine body images of 62 patients with anorexia nervosa, 45 patients with bulimia nervosa, and 40 female and 39 male control subjects. Body size overestimation was most distinct in the two patient groups. Self-ideal discrepancy was highest in bulimia nervosa. Estimation of the society's ideal female body in all three female groups did not differ from men's perception of the most attractive female body. Congruence of ideals of female attractiveness in patients, female, and male control subjects and described differences between patients and female controls support the theory that body image disturbance is a problem of processing self-referential information regarding body image rather than a problem of processing body image related information per se.     

Joint drumming: social context facilitates synchronization in preschool children

The human capacity to synchronize body movements to an external acoustic beat enables uniquely human behaviors such as music making and dancing. By hypothesis, these first evolved in human cultures as fundamentally social activities. We therefore hypothesized that children would spontaneously synchronize their body movements to an external beat at earlier ages and with higher accuracy if the stimulus was presented in a social context. A total of 36 children in three age groups (2.5, 3.5, and 4.5 years) were invited to drum along with either a human partner, a drumming machine, or a drum sound coming from a speaker. When drumming with a social partner, children as young as 2.5 years adjusted their drumming tempo to a beat outside the range of their spontaneous motor tempo. Moreover, children of all ages synchronized their drumming with higher accuracy in the social condition. We argue that drumming together with a social partner creates a shared representation of the joint action task and/or elicits a specific human motivation to synchronize movements during joint rhythmic activity.     

A positive information logic for inferential information

Performing an inference involves irreducibly dynamic cognitive procedures. The article proposes that a non-associative information frame, corresponding to a residuated pogroupoid, underpins the information structure involved. The argument proceeds by expounding the informational turn in logic, before outlining the cognitive actions at work in deductive inference. The structural rules of Weakening, Contraction, Commutation, and Association are rejected on the grounds that they cause us to lose track of the information flow in inferential procedures. By taking the operation of information application as the primary operation, the fusion connective is retained, with commutative failure generating a double implication. The other connectives are rejected.
