Learning to Manipulate and Categorize in Human and Artificial Agents

This study investigates the acquisition of integrated object manipulation and categorization abilities through a series of experiments in which human adults and artificial agents were asked to learn to manipulate two‐dimensional objects that varied in shape, color, weight, and color intensity. The analysis of the obtained results and the comparison of the behavior displayed by human and artificial agents allowed us to identify the key role played by features affecting the agent/environment interaction, the relation between category and action development, and the role of cognitive biases originating from previous knowledge.     

Not so Sweet Revenge: Unanticipated Consequences of High-Intensity Sweeteners

While no single factor accounts for the significant increases in overweight and obesity that have emerged during the past several decades, evidence now suggests that sugars, in general, and sugar-sweetened beverages, in particular, may be especially problematic. One response to this concern has been an explosion in the availability and use of noncaloric sweeteners as replacements for sugar. While consumers have been led to believe that such substitutes are healthy, long-term epidemiological data in a number of cohorts have documented increased risk for negative outcomes like type 2 diabetes, heart disease, and stroke among users of artificial sweeteners. Experimental data from animals has provided several plausible mechanisms that could explain this counterintuitive relationship. In particular, my research has demonstrated that artificial sweeteners appear to interfere with basic learned, predictive relations between sweet tastes and post-ingestive consequences such as the delivery of energy. By interfering with these relations, artificial sweeteners inhibit anticipatory responses that normally serve to maintain physiological homeostasis, and over the long term, this interference could result in negative health effects like those seen in the human cohort studies. These data suggest that reducing the consumption of all sweeteners is advisable to promote better health.     

Patterns of psychotherapy development: A mixed-method analysis using assimilation indices

Understanding how assimilation develops is essential in promoting personal change. By attending to signs or indices of assimilation in the speech of clients, therapists can use this process to assess how the therapy is developing and to tailor intervention. The system of assimilation indices was developed to use assimilation to understand the process of change. This system signals five sub-processes of assimilation: external distress, pain, noticing, decentring, and action. This study consisted of a longitudinal mixed-method analysis, following a multiple cases embedded design. The system of assimilation indices was applied to the recordings of nine psychotherapies and contrasted with both the outcome of the therapy and the perspectives of the therapists and clients about their therapy process. The results show that the system of indices is useful in understanding multiple pathways for assimilation. The system of indices is seen as a useful tool for understanding assimilation and as having clinical value in anticipating challenges to the success of the therapy. This study also shows how the indices are sensitive to the nuances in the change process observed in clinical settings.     

A pseudo-binary interdiffusion study in the β-Ni(Pt)Al phase

Interdiffusion study is conducted in the Ni-rich part of the β-Ni(Pt)Al phase following the pseudo-binary approach. Interdiffusion coefficients over the whole composition range considered in this study increases with increase in Pt content, which is in line with the theoretical study predicting the decrease in vacancy formation and migration energy because of Pt addition. The trend of change in diffusion coefficient with the increase in Ni and Pt contents indicates that Pt preferably replaces Ni antisites.     

Ethical Ambiguities in Participatory Action Research With Unauthorized Migrants

There is increased recognition of the importance of well-designed scholarship on how immigration status and policies impact migrants in the United States, including those who are unauthorized. Some researchers have looked to community-based and participatory methods to develop trust, place migrants’ voices at the forefront, and engage collaboratively in using research as a tool for social change. This article reviews three ethical ambiguities that emerged in the process of a series of participatory action research (PAR) projects with migrants in the United States, many of whom were unauthorized. Specifically, three themes are discussed: (a) the tension between the human desire to respond to injustices, and the challenges of doing so in ways that recognize one’s privilege and power as an outsider and supports the migrants’ agency and autonomy; (b) the complex definition, explanation, and dimensions of “risk”; and (c) the complexity of using a methodology (PAR) that prioritizes participants’ collective identity and community in the context of regulations that are designed primarily to protect individuals.     

The Community Story,Relationality and Process: Bridging Tools for Researching Local Knowledge in a Peri‐urban Township

In intervening in social challenges impacting local communities, Western forms of dispute/conflict resolution have been critiqued for imparting norms, values and practices that marginalise worldviews of indigenous people. From a decolonizing stance, indigenous scholars have emphasised the need for recovery of ‘lost’ values, beliefs and practices to advance indigenous knowledge. We highlight some of the conceptual challenges associated with applying ‘indigenous knowledge’ and culture‐specific ‘indigenous methodologies’ to a marginalised peri‐urban, ethnically plural township community situated on the outskirts of Johannesburg, South Africa. In embracing the mutuality of indigenous and Western knowledge forms, we explore three elements: the community story, relationality and process in relation to initial engagements with our study community. We attempt to transcend the dualism between ‘Western’ epistemologies and ‘indigenous knowledge’ through these ‘bridging concepts’. What is offered is not a formula or model but an orientation that aims to foster mutual learning through collaborative partnerships within and between communities and researchers with a view to inspiring possibilities for creative and meaningful solutions for violence prevention and dispute/conflict resolution.

Quels sont les prédicteurs des comportements associés au respect des règles d’hygiène en soins infirmiers en cours de formation ?

We present a study whose aim is to analyse the predictability of behaviors associated with breaches of hygiene rules based on the constructs of the theory of planned behavior and implementation of intention. One hundred and fifty nursing students replied to a questionnaire following their theoretical training and then after returning from practical placement during which some were observed in a professional situation. The results highlighted the fact that self-reported behavior was associated with behavior observed in context with regard to the observance of rules governing hand hygiene and the decontamination of surfaces. Self-reported behavior is explained successively by behavioral control, intention and implementation of intention when the latter relates to behavioral reflexivity. These results are discussed from the point of view of nurse training practices.     

The person-centred approach as an ideological discourse: a discourse analysis of person-centred counsellors' accounts on their way of being

In accord with humanistic psychology, the person-centred approach (PCA) highlights individuality and is characterised by subjectivity and freedom vs. objectivity and determination. This study endeavoured to define how person-centred counsellors position themselves within PCA. In order to employ a critical frame of mind, analysis focused on identifying constructions, contradictions and functions of language that pointed to power relations. This study revealed a power relation between PCA and the counsellors, displaying five discourses: the philosophical discourse, the discourse of freedom, the discourse of religion/spirituality, the discourse of militarism and the discourse of eros (love). PCA is thought to empower the client in relation to its respectful and non-directive, therapeutic framework. Analysis suggests that despite rhetorical endorsement of PCA as enabling, the approach has implications for subjectivity and practice regarding the counsellor him/herself. Adhesive attachments closely resembling religious and erotic ones seem responsible for dogmatic and militaristic phenomena as described by participants. Strong emotions such as pride and guilt are indicative of this adhesive investment. Furthermore, the analysis shows that as the discourse of freedom becomes embedded in the philosophical discourse of PCA, it has connotations of truth. Lastly, the discourse of religion/spirituality seems to organise PCA in terms of meaning coherence.     

Spirituality and child protection in early childhood education: a strengths approach

In recent international and Australian early childhood curriculum guidelines and child-protection policies, the need for teachers of young children to foster spirituality has been highlighted. However, what this might mean in practice has not been widely explored. This article addresses the more controversial issue of spiritual abuse and the right of children to protection in terms of spiritual development. We present a critique of current definitions taken from research and policy documents. Qualitative data provide the research background. Vignettes are presented to give examples of what spiritual harm might look like in practice. Finally, a strengths-based approach is introduced and strategies are suggested in order to explore the potential of the Strengths Approach (a social justice approach originating from social service practice) to aid early years’ teachers to create spiritually protective learning environments. This approach recognises and values children’s holistic development and wellbeing and supports them to appreciate, engage with and question the world around them with a resilient spirit.     

Deciding as Intentional Action: Control over Decisions

Common-sense folk psychology and mainstream philosophy of action agree about decisions: these are under an agent's direct control, and are thus intentional actions for which agents can be held responsible. I begin this paper by presenting a problem for this view. In short, since the content of the motivational attitudes that drive deliberation and decision remains open-ended until the moment of decision, it is unclear how agents can be thought to exercise control over what they decide at the moment of deciding. I note that this problem might motivate a non-actional view of deciding—a view that decisions are not actions, but are instead passive events of intention acquisition. For without an understanding of how an agent might exercise control over what is decided at the moment of deciding, we lack a good reason for maintaining commitment to an actional view of deciding. However, I then offer the required account of how agents exercise control over decisions at the moment of deciding. Crucial to this account is an understanding of the relation of practical deliberation to deciding, an understanding of skilled deliberative activity, and the role of attention in the mental action of deciding.
