The quality of parenting of individuals who had failed to thrive as children

Parenting behaviour is determined by a range of factors including personality, psychopathology, values, social support, child characteristics and socio-cultural influences. It has also been suggested that an individual's style of child-rearing is influenced by the style of parenting that they experienced as children. The relationships between children who fail-to-thrive and their parents are often characterized by interactional difficulties. Previous research using retrospective accounts suggested that mothers of children who fail-to-thrive for non-organic reasons themselves showed high levels of abuse, neglect, and deprivation during their childhoods. However, to date no one has investigated prospectively what kinds of parents failure-to-thrive individuals become. This paper examines the parenting experiences of individuals who had received psychosocial intervention for their non-organic failure-to-thrive as children over 20 years ago. Results suggest that where initial intervention failed to bring about long-term changes in family interactional patterns, there was a greater incidence of failure-to-thrive in the next generation. These families were characterized by dissatisfaction with the child, high levels of stress associated with the parenting role, and low levels of social support. However, where the family environment in the original study had changed substantially, the former clients' outcomes were more positive with their own children. These parents tended to find interaction with their children more rewarding, had good support networks and low levels of stress. The characteristics of particular cases are discussed in detail to illustrate differences between these two groups of individuals.

Exploring eye movement analysis as a measure of selective visual attention in brain injured individuals

Primary Objective: To investigate the utility of using a new method of assessment for deficits in selective visual attention (SVA). Methods and Procedures: An independent groups design compared six participants with brain injuries with six participants from a non-brain injured control group. The Sensomotoric Instruments Eye Movement system with remote eye-tracking device (eye camera), and 2 sets of eight stimuli were employed to determine if the camera would be a sensitive discriminator of SVA in these groups. Main Outcomes and Results: The attention profile displayed by the brain injured group showed that they were slower, made more errors, were less accurate, and more indecisive than the control group. Conclusions: The utility of eye movement analysis as an assessment method was established, with implications for rehabilitation requiring further development. Key words: selective visual attention, eye movement analysis, brain injury

Estimation of the size of onset of sexual maturity in Nephrops norvegicus (L.).

Size at onset of maturity (SOM) was estimated for both male and female Nephrops from primary sexual characteristics and morphometric traits. SOM estimated from primary sexual characteristics based on histological examination of the gonad ranged from 15.1 mm carapace length (CL) in males to 22.9 mm CL in females. Nephrops morphometric maturity, or change in allometric growth of body parts, was estimated from appendix masculina and cutter claw lengths in males and abdomen width in females from two sites in the Irish Sea. Two regression techniques were used to estimate morphometric maturity. Estimated SOM from morphometric characteristics ranged from 23.2 to 27.6 mm CL in females and from 25.9 to 31.0 mm CL in males. Spatial variation in SOM was observed in Nephrops from different parts of the Irish Sea.

Tuberculosis among Iron Age individuals from Tyva, South Siberia: palaeopathological and biomolecular findings

The study focuses on the evidence for tuberculosis apparent in an Iron Age population recovered from the cemetery of Aymyrlyg, Tyva (Tuva), South Siberia. A recent wholly molecular study of five of the cases confirmed the presence of Mycobacterium tuberculosis (MTB) complex DNA in four of the individuals. In all cases the disease was caused by strains of Mycobacterium bovis rather than Mycobacterium tuberculosis and represents the first positive identification of the bovine form of the disease in archaeological human remains. Details of the palaeopathological characteristics of the cases are provided in the current paper, while the molecular observations are extended to include a quantitative evaluation of the surviving mycobacterial DNA using real-time PCR. The observation that bovine tuberculosis was the pathogen responsible is discussed in terms of current understanding of the evolution of the MTB complex as well as the implications for future ancient DNA studies in this area.

Distinct patterns of peripheral HIV-1-specific interferon- gamma responses in exposed HIV-1-seronegative individuals.

It is unclear how human immunodeficiency virus (HIV) type 1–specific immune responses in exposed seronegative (ESN) individuals differ from those in HIV-1–infected subjects. By use of overlapping peptides spanning Gag, Tat, Nef, Vif, Vpr, and Vpu, peripheral blood mononuclear cells from ESN individuals, their seropositive (SP) partners, and unexposed seronegative control subjects were screened for interferon-? production. Responses were more frequent (95.7% vs. 20%), of a higher magnitude (9-fold), and of wider breadth (median number of peptides recognized, 18 vs. 2.5) in SP than in ESN individuals. Peptides recognized by ESN individuals were less frequently recognized by their SP partners. SP subjects infrequently recognized peptides from Vif, and such responses were subdominant; among ESN individuals, this HIV-1 protein was most frequently recognized. Immunodominant peptides recognized by SP subjects tended to be from relatively conserved regions, whereas peptides recognized by ESN individuals were associated with slow disease progression.
