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.     

CCTV Observation: The Effects of Event Type and Instructions on Fixation Behaviour in an Applied Change Blindness Task

Little is known about how observers' scanning strategies affect performance when monitoring events in closed‐circuit television (CCTV) footage. We examined the fixation behaviour of change detectors and non‐detectors monitoring dynamic scenes. One hundred forty‐seven participants observed mock CCTV videos featuring either a mock crime or no crime. Participants were instructed to look for a crime, to look for something unusual or simply to watch the video. In both videos, two of the people depicted switched locations. Eye movements (the number of fixations on the targets and the average length of each fixation on targets) were recorded prior to and during the critical change period. Change detection (24% overall) was unaffected by event type or task instruction. Fixation behaviour differed significantly between the criminal and non‐criminal event conditions. There was no effect of instructions on fixation behaviour. Change detectors fixated for longer on the target directly before the change than did non‐detectors. Although fixation behaviour before change predicted change detection, fixation count and durations during the critical change period did not. These results highlight the potential value of studying fixation behaviour for understanding change blindness during complex, cognitively demanding tasks (e.g. CCTV surveillance).

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.     

Tackling Germany’s Demographic Skills Shortage: Permanent Settlement Intentions of the Recent Wave of Labour Migrants from Non-European Countries

Confronted with structural demographic challenges, during the last decade European countries have adopted new labour migration policies. The sustainability of these policies largely depends on the intentions of migrants to stay in their country of destination for the long term or even permanently. Despite a growing dependence on skilled labour migrants, very little information exists about the dynamics of this new wave of migration and existing research findings with their focus on earlier migrant generations are hardly applicable today. The article comparatively tests major theoretical approaches accounting for permanent settlement intentions of Germany’s most recent labour migrants from non-European countries on the basis of a new administrative dataset. Although the recent wave of labour migrants is on average a privileged group with regard to their human capital, fundamentally different mechanisms are shaping their future migration intentions. In contrast to neo-classical expectations, a first path highlights economic factors that determine temporary stays of a creative class benefiting from opportunities of an increasingly international labour market. Instead, socio-cultural and institutional factors are the decisive determinants of a second path leading towards permanent settlement intentions. Three main factors—language skills, the family context and the legal framework—make migrants stay in Germany, providing important implications for adjusting and strengthening labour migration policies in Europe.     

Implementing the Boulder Model of Training in a Psychology Training Clinic

The scientist–practitioner (S–P) model of training has guided professional psychology in the United States for nearly six decades. However, since its inception, the model has been hotly debated and implementation of the model has been chronically problematic. One counseling psychologist who is working as both a faculty member and psychology training clinic director describes how scientific principles can be retained in a practice setting. He overviews the Boulder model of training, provides a brief review of the psychology training clinic (PTC), describes his current work setting and unique faculty appointment, and outlines five strategies for integrating science and practice in applied clinical settings. He also highlights how embracing the Boulder model has promoted a strong professional identity and presents the PTC as a model professional home for S–Ps.     

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.
