Energetic effects of dopants on the eutectoid decomposition of Nb–Si in situ composites

The influences of doping elements (Ti, Zr, Hf, V, Ta, Cr, Mo, W and Al) on the heats of formation of Nb, Nb₅Si₃ and Nb₃Si have been studied using first-principles pseudopotential plane-wave method based on density functional theory. Site preferences of dopants in Nb₅Si₃ and Nb₃Si intermetallics are first determined by comparing the heats of formation of the systems with different site occupations of the doping atoms. The partitionings of dopants between the equilibrium phases Nb and Nb₅Si₃ of Nb–Si in situ composites are then discussed and compared with experimental results. Phase partitioning behaviours of the alloying elements are found to depend strongly on the number of their valence electrons. By calculating the enthalpy of reaction regarding the eutectoid decomposition of Nb₃Si phase, we conclude that Ta is a Nb₃Si stabiliser while other dopants destabilise Nb₃Si at the investigated concentration.     

Genetic Indigenisation in ‘The People of the British Isles’

In 2007, Channel 4 screened Face of Britain, a documentary about the genetic mapping of Britain. Face of Britain promised to reveal ‘who we really are’ by tracing genetic links back to ancient Celts, Anglo-Saxons, Vikings and Normans. This article situates Face of Britain within the wider racial and national politics that it is invariably caught up in, and examines how ‘race’ and racial thinking are reconfigured in ways that are both ‘old’ and ‘new’. Face of Britain constitutes an interesting case study to examine how ideas of indigeneity are produced and naturalised in scientific discourses and practices. Here, indigeneity is mobilised through three sub-narratives: the ‘vanishing indigene’; the promise of facial recognition; and DNA and national relatedness. The analysis reveals how some people of the British Isles are naturalised as indigenous by virtue of their ancestral presence in this land through a combination of genetic and photographic technologies. In short, blood and soil are intertwined, with genes as mediators between ancestors and contemporary inhabitants of Britain. Furthermore, the invisible genetic connection is made visible through the creation of ‘average faces of Britain’, which is considered here as a contemporary version of physiognomy. In conclusion, Face of Britain testifies to the reconfiguration of ‘racial thinking’ in contemporary science, through what ultimately amounts to the genetic indigenisation of white Britons. Consequently, this study lends itself to racialised politics of land claims that resonate with, but are different from, indigenous politics in other contexts, namely with regards to the relationship to whiteness.     

EMBODIED COGNITION,CHARACTER FORMATION,AND VIRTUE

The theory of embodied cognition makes the claim that our cognitive processes are, at their core, sensorimotor, situated, and action‐relevant. Our mental system is built primarily to control action, and so mind is formed by the nature of the body and its interactions with the world. In this paper we will explore the nature of virtue and its formation from the perspective of embodied cognition. We specifically describe exemplars of the virtue of compassion (caregivers of individuals with developmental disabilities in L'Arche communities), speculating as to what might have been the formative influences in their character development. Embodied formation is understood in the context of the openness of human cortical systems to formation by social interactions, and in terms of the openness to reorganization and change of complex dynamical systems. Specific formative influences explored include interpersonal imitation, social attachment, language, and story.     

Towards a queer dharmology of sex

Lay practitioners of Buddhism, especially lesbian/gay/bisexual/transgender/queer persons, are given little guidance by the traditional Dharmology (Buddhist theology) of sex. The most extensive discussions are the detailed prohibitions in the monastic rule, which focus on the mechanics of sex rather than on love and relationships. What advice there is on sex for lay persons is either vague or over‐determined by its cultural context. Christianity, despite being homophobic and mistrustful of sex, has developed a positive attitude towards sex within heterosexual marriage. An investigation of this suggests a Dharmology of sex as relationship, based on central Buddhist doctrines such as interdependent arising. This Dharmology can be strengthened by queering it with reference to Harry Hay's notion that gay subject–subject consciousness is more compatible with Buddhist non‐duality than the hetero subject–object consciousness. It can be claimed, therefore, that Buddha Nature, and Buddhism itself, is queer.     

Spiritual Maturity and Meaning-Filled Relationships: A Sociological Perspective

SUMMARY

The process of self-development, spiritual maturity and the construction of new meaning-filled relationships in late life are analyzed through the actions and interactions observed in the biographical case history of Sarah-Patton Boyle. Atchley's four stages in the process of retirement applied to the case of Sarah-Patton Boyle identifies the changes in her social roles and relationships and the struggle to maintain a positive self-view in the midst of socio-environmental changes. The struggle to continue “spiritual self” identity and ties with the church are discussed.     

Unconscious phantasy as an obstacle and as a stimulus to knowledge

This paper underlines and explores the connections between emotional and cognitive development at a very early stage, starting from the psychoanalytic psychotherapy of a 4-year-old boy with autistic features. Development of the personality and development of the mind are shown to proceed together and to be interwoven when the therapist starts to help the child to modulate the terror and the rage related to separation. The development of the idea of a good nipple and the Introjection of it as a mental structure is considered an important step on the way towards separation between mother and baby and towards the formation within the baby self of a space where symbols of the external world can be placed. Autistic features are considered as an extreme form of denial of both internal and external reality.     

Light and movement: making contact with a traumatised and embattled latency girl

This paper shows a child psychotherapist learning and developing her technique as she attempts to make contact with a child who is extremely hard to reach. It is based on the first two years of three-times-weekly intensive psychotherapy of a latency girl who had little faith in a helpful therapeutic relationship. Her defences against such a relationship were entrenched and hard to shift. In this clinical work, the psychotherapist relies on close observation and her countertransference to develop a relationship with the child, in order to begin to make sense of her non-verbal emotional experience and communication.     

Beyond brands: Happy adolescents see the good in people

How does happiness affect adolescents’ stereotypes of other people? Using a collage methodology with 60 adolescents aged 12–18, we find that happier adolescents hold more positive stereotypes of others compared to those who are less happy. We also find that happier adolescents are less likely to form impressions of people based on surface level cues such as the products and brands that people own. Finally, our results show that happier adolescents have a more nuanced view of others, (e.g., some cool kids wear expensive brands, but some shop at thrift stores), compared to their less happy counterparts, who tend to oversimplify their view of others (e.g., all cool kids wear expensive brands, all doctors drive a BMW).     

Reminiscence bump in autobiographical memory: Unexplained by novelty,emotionality, valence,or importance of personal events

People tend to recall a disproportionately large number of personal events from their adolescence and early adulthood. This “reminiscence bump” has been examined extensively, but its causes remain unclear. In this Internet-based experiment, nearly 3,500 participants were given 10 cue words and were asked to describe the personal events that came to mind. Furthermore, they were asked to date each event and to indicate whether it was a first-time experience. Finally, the participants were asked to rate the strength of the emotional reaction to the event or the valence or the importance of the event. Surprisingly, the reminiscence bump consisted of relatively fewer novel, emotional, important positive or negative events. This result increases the likelihood of an alternative explanation—namely, that memory is generally enhanced in adolescence and early adulthood. However, this account has not been tested directly.     

Spirit books: promoting conversation with picture books

The focus of this article is an annotated bibliography of over seventy select picture books and guidelines for adults reading these books to children ages three through nine. Preceding these is an essay which contextualizes and explains them. Following the bibliography is a set of twenty ‘Guidelines for Reading Aloud and Talking about Books’ to help adults validate and support the spiritual experiences of children. The annotated bibliography – The Spirit Book List– includes picture books which are inclusive, interfaith, and cross-cultural (although all are in English). They have been chosen to stimulate conversation between adults and children ranging in age from three to nine years on spirituality, specifically on the following six themes: (1) The Golden World (awe and reverence in the face of Creation); (2) Alone Unplugged the value of solitude and silence; (3) Widening the Circle (embracing other beings, both animal and human, and recognizing one’s interdependence with other life forms); (4) Wisdom-seeking (seeking true value); (5) Becoming Your Own Person (discovering one’s uniqueness and one’s place in the world); and (6) Peace-making (promoting peace between individuals and countries). All these books also meet high standards for both text and illustrations.
