This paper investigates the impact of related variety on regional employment growth in Finland between 1993 and 2006 by means of a dynamic panel regression model. We find that related variety in general has no impact on growth. Instead, after separating related variety among low-and-medium-tech sectors from related variety among high-tech sectors, we find that only the latter affects regional growth. Hence, we find evidence that the effect of related variety on regional employment growth is conditioned by the technological intensity of the local sectors involved. [ABSTRACT FROM AUTHOR]

Acetabular labral tears are recognized as a source of hip pain in the general, athletic and dance populations. The complicated, often end-range movement patterns required of dancers make them especially susceptible to hip injury. Labral tears at the hip can significantly impact the success of a dancer's career. Currently there is little research regarding acetabular labral tears in the dance population. This literature review highlights current knowledge of labral structure and function, the epidemiology and etiology of tears, and conservative and surgical treatment. According to the literature, labral tears are found most often in the anterior quadrant of the labrum. Both traumatic and non-traumatic mechanisms of injury are reported, of either minimal or significant severity. Physical therapy tests have poor specificity to diagnose labral tears. The majority of reviewed studies show positive outcomes post arthroscopy in the general population and in athletes. Further research is necessary to investigate optimum rehabilitation and long-term outcomes of conservative and surgical treatment for the dance population. [ABSTRACT FROM AUTHOR]

This article seeks to show how Human Resource Management and Development practitioners can develop an ethics of practice by adopting a Humanistic Action Research approach toward their Continuing Professional Development (CPD). Central to this approach is the development of reflective practice skills, in itself a journey of development. I aim to give a flavour of what this practice has meant for me as a professional educator by sharing an account of my own CPD using this approach. This approach is for the mature practitioner and it is located within Humanistic Action Research: to be appropriate, it necessitates a maturity of ego and not simply professional maturity and status. The article will discuss what this maturation process involves and will show its centrality to reflective practice. Within this framework of human inquiry, CPD requires an undertaking to engage in first person Action Research, where ‘I’ am the subject and object of my inquiry. At the heart of this approach is the pragmatic question at the centre of any approach to CPD ‘How do I improve my practice?’. [ABSTRACT FROM AUTHOR]

The very low density (VLDL) apolipoproteins of 12 male patients with gout have been studied by analytical isoelectric focusing. The relative percentage distribution of the C apolipoproteins was calculated and compared with that from 12 normolipidaemic and 12 'lipid-matched' controls. In the gout patients apolipoprotein CII (apo CII) represented 19.6% of the VLDL C proteins and the CII/CIII2 ratio was 0.57. In the normolipidaemic controls apo CII represented 28.8% and in the lipid-matched controls 33.1% of VLDL apo C, and the CII/CIII2 ratio approached one in each control group. These differences were significant. This suggests that a reduction in VLDL apo CII may predispose to the hypertriglyceridaemia that is commonly found in patients with gout. [ABSTRACT FROM PUBLISHER]

The urinary total hydroxyproline:creatinine ratio was measured on samples collected from 18 boys and 11 girls referred to a children's hospital because of small stature. Any serious degree of growth hormone deficiency was excluded and each child's growth and development was recorded over the following year. The hypothesis that the average hydroxyproline:creatinine ratio on random urine samples may be used to predict height velocity was examined. Such a prediction would have been incorrect on 35% of occasions, and it is concluded that this investigation cannot be used reliability to predict growth in height; it is probably only useful with sequential studies of an individual child over short periods while monitoring therapy.

Ninety-six juvenile onset type diabetics showed an increase in the frequency of HLA B8 and B15 and a decrease in frequency of HLA B7 antigens. Sixty-four maturity onset diabetics showed no disturbance in the frequency of these antigens. Fifty-four of the juvenile onset type diabetics, with an average duration of disease of 3-2 years were tested for the presence of islet cell antibodies (ICAs). Thirty-two per cent were positive, the incidence decreasing from 70% in those patients tested within 1 year of diagnosis to zero in those patients tested more than 5 years after diagnosis. No correlation was found between the incidence of ICAs and either cell-mediated immune reactions or HLA type. B15 positive patients were associated with cell-mediated immune reactions to pancreatic antigens and with the presence of other tissue autoantibodies. HLA phenotypes were not associated with environmental data. Diabetic siblings had identical HLA A-B haplotypes more often than could be expected to occur by chance. [ABSTRACT FROM AUTHOR]

Forty-three newly diagnosed insulin-dependent diabetics and thirty control subjects have been examined for cellular hypersensitivity to different pancreatic preparations, rat liver mitochondria and Coxsackie B4 virus. Evidence for cellular hypersensitivity to the pancreatic preparations was shown in the diabetic group, in whom the hypersensitivity to the pancreatic preparations was found to correlate with hyper- sensitivity to rat liver mitochondria. Hypersensitivity to Coxsackie B4 virus was not found to differ significantly in the diabetic and control groups. Hypersensitivity to liver mitochondria appeared to decrease over a 1-year period. There was an indication that hypersensitivity to Coxsackie B4 was greatest 3 months after diagnosis. [ABSTRACT FROM AUTHOR]

Leucocyte migration tests with rat liver mitochondria have been performed in eighteen patients with juvenile diabetes mellitus and in fifteen healthy controls. Leucocytes from normal subjects showed no inhibition of leucocyte migration. whereas inhibition occurred in twelve out of eighteen diabetics. The active component appeared to be in the inner membranes of the mitochondria in seventeen patients, whilst leucocytes from one patient showed inhibition to outer membrane fragments. Leucocyte migrations tests were performed in a further thirty-five patients, again using rat liver mitochondria as antigen, and sera from these patients was investigated for the presence of tissue autoantibodies. In those patients having a positive leucocyte migration test there was a higher incidence of circulating antibodies than in the group where white cells showed no inhibition but this did not reach statistical significance.

Ischaemic heart disease mortality is much lower in Southern Italy than in the U.K. and this is not entirely explained by differences in classical risk factors. Differences in antioxidant intake, affecting free radical peroxidation of plasma lipoproteins, may be relevant. Therefore, dietary intake, antioxidant status and plasma lipid peroxidation were compared in healthy young persons eating typical regional diets from Naples (22) and Bristol (26). The Naples group consumed more fresh tomatoes, more fat as monounsaturates (from olive oil) and had higher plasma levels of the lipid antioxidants vitamin E (mean (SD; 95% CI) 29.1 (4.5; 26.8 to 31.3) vs 25.1 (3.86; 23.4 to 26.8) μmol I, P=0.005) and beta-carotene (4.74 (1.2; 4.14 to 5.34) vs 2.85 (0.8; 2.5 to 3.2) μmol. I, P<0.001). Intakes of vitamin C, total uncooked fruit and vegetables, plasma vitamin A, serum selenium and copper levels were similar. All indices of plasma lipid peroxidation were significantly lower in the Naples group: conjugated dienes (median (interquartile range; non-parametric 95% CI)) 29 (21.5-39.9; 24 to 36.7) vs 41.5 (37-48.5; 38 to 44.5) μmol. I, P<0.001; diene conjugation index 1.38 (1.02-1.55; 1.06 to 1.49) × 10 vs 1.57 (1.43-1.74; 1.44 to 1.71) × 10, P=0.019; lipid peroxides (geometric mean (95% CI)) 1.24 (1.12 to 1.37) vs 4.58 (3.84 to 5.46) μmol. I, P<0.001. Low levels of free radical peroxidised lipoproteins in Southern Italians may contribute to their comparatively low incidence of ischaemic heart disease and may result from increased antioxidant protection by higher plasma vitamin E and beta-carotene levels, derived from high olive oil and tomato intakes.
