Stimulation seeking and intelligence: a prospective longitudinal study

The prediction that high stimulation seeking 3-year-olds would have higher IQs by 11 years old was tested in 1,795 children on whom behavioral measures of stimulation seeking were taken at 3 years, together with cognitive ability at 11 years. High 3-year-old stimulation seekers scored 12 points higher on total IQ at age 11 compared with low stimulation seekers and also had superior scholastic and reading ability. Results replicated across independent samples and were found for all gender and ethnic groups. Effect sizes for the relationship between age 3 stimulation seeking and age 11 IQ ranged from 0.52 to 0.87. Findings appear to be the first to show a prospective link between stimulation seeking and intelligence. It is hypothesized that young stimulation seekers create for themselves an enriched environment that stimulates cognitive development.     

Pressure-induced structural transition in UGa2

High-pressure X-ray diffraction has been performed on UGa₂ up to 20?GPa using a diamond anvil cell. UGa₂ exhibits the AlB₂-type structure with space group P6/mmm at room temperature and atmospheric pressure. At about 16?GPa a reversible structural transformation to a tetragonal phase was observed. The bulk modulus of the AlB₂-type phase has been determined to be ～100?GPa, which is comparable to rare earth digallides like TmGa₂ and HoGa₂.     

Tuning into the psychotic wavelength: Psychoanalytic supervision for mental health professionals

In this paper, material is presented from supervision groups run for mental health professionals in different mental health settings. I will argue that a psychoanalytic framework, which puts the transference and countertransference at the centre of clinical practice, offers an important model for thinking about psychosis and psychotic means of communication. When staff are able to ‘tune in’ to their patients' communications it can help to change a patient's monologue about his/her delusional world into a meaningful dialogue about their emotional world.     

Applicability of Scheil–Gulliver solidification model in real alloy: a case study with Cu-9wt%Ni-6wt%Sn alloy

The present work explores the possibilities of the application of Scheil–Gulliver equation in modelling the solidification of a real alloy. For this study, Cu-9 wt%Ni-6 wt%Sn alloy was chosen which exhibits profuse micro-segregation during solidification, and hence easy to quantify experimentally. Also, this alloy is spinodally strengthened high strength copper alloy and has industrial importance. In this study, thermodynamic assessment using Scheil–Gulliver solidification model was carried out. Subsequently, the assessed result was compared with the experimentally obtained results from energy-dispersive X-ray spectroscopy analysis, and a good agreement was observed between these results. Therefore, it could be concluded that the solidification of this particular alloy system can be modelled using Scheil–Gulliver equation.     

Both odor identification and ApoE-ε4 contribute to normative cognitive aging

Research indicates that apoliprotein E (ApoE) plays a role in the development of Alzheimer's disease (AD) and possibly in the cognitive decline associated with normative aging. More recently, researchers have shown that ApoE is expressed in olfactory brain structures, and a relationship among ApoE, AD, and olfactory function has been proposed. In the current analyses, we investigated the contribution of ApoE and odor identification in decline trajectories associated with normative cognitive aging in various domains, using longitudinal data on cognitive performance available from the Swedish Adoption/Twin Study of Aging. Data on both ApoE status and olfactory functioning were available from 455 individuals ranging in age from 50 to 88 years at the first measurement occasion. Odor identification was measured via a mailed survey. Cognitive performance was assessed in up to 5 waves of in-person testing covering a period of 16 years. Latent growth curve analyses incorporating odor identification and ApoE status indicated a main effect of odor identification on the performance level in three cognitive domains: verbal, memory, and speed. A main effect of ApoE on rates of decline after age 65 was found for verbal, spatial, and speed factors. The consistency of results across cognitive domains provides support for theories that posit central nervous system-wide origins of the olfaction-cognition-ApoE relationship; however, olfactory errors and APOE ε4 show unique and differential effects on cognitive trajectory features.     

The Three Selves of Adulthood: Cultural Conceptions of Self Among Oriya Hindu Women

This essay examines the cultural conceptions of self among Oriya Hindu women who live in the temple town of Bhubaneswar in Orissa, India. It explores the temporal dimension of these conceptions during adulthood. While Hindu understandings about the relative permeability of the human body and its potential for transformation lead to an interdependent conception of the self, each of the three phases of adulthood—young adulthood, mature adulthood and old age—produces its own particular variant. The particularity of each variant derives from the cultural meanings attached to each life-phase and the social context of these women’s lives. The critical variable appears to be the predominant goal of each life-phase. The goals of assimilation in young adulthood, dominance and centrality in mature adulthood and coherence in old age lead to an interdependent conception of the self that changes, during the course of adulthood, from ‘emergent’ to ‘encompassing’ to ‘non-interdependent’.
