BACKGROUND: Research on the subject of insight has been hampered by difficulties in definition and reliable measurement. METHODS: We compared several rating scales to measure insight on a group of 33 psychotic patients as well as assessing patients' psychopathology, clinical characteristics and cognitive functioning. RESULTS: Most currently used scales showed a high degree of inter-correlation. Measures of insight related strongly to the presence of delusions; grandiosity (inversely), and depression (positively). Higher insight scores correlated with indices of treatment compliance and inversely with substance abuse. Measures of pre-morbid IQ and impaired executive functioning, including the Wisconsin Card Sorting Test were not associated with poor insight. CONCLUSIONS: The study highlights aspects of psychopathology and clinical variables particularly related to insight and supports the continued use of standardized scales in further research in this area. 相似文献

Alveolar Type II cells in the rat respond to severe, acute ozone injury (3 ppm ozone for eight hours) by increasing their
intracellular pool of surfactant; however, the newly stored surfactant is abnormal in composition. Lamellar bodies isolated
between 24 and 96 hours after ozone exposure contained significantly more cholesterol in relation to phosphatidylcholine than
did controls. By contrast, the cholesterol content of surfactant isolated from alveolar lavage remained unchanged throughout
an 8-day post-ozone period. The total protein content of lamellar bodies in relation to phosphatidylcholine was significantly
decreased at 24 and 48 hours post-ozone. Analysis of lamellar body proteins by sodium dodecyl sulfate-polyacrylamide gel electrophoresis
revealed that the amount of a 14 kDa proteolipid was greatly reduced at the end of the eight-hour ozone exposure and remained
low for at least 48 hours. This proteolipid appeared to be a specific lamellar body component since it was not detected in
extracellular surfactant. The findings indicate that oxidative alveolar stress initiates characteristic alterations in both
lipid and protein constituents of stored surfactant, without perturbation in the composition of extracellular surfactant. 相似文献

This article considers a structured latent curve model for multiple repeated measures. In a structured latent curve model, a smooth nonlinear function characterizes the mean response. A first-order Taylor polynomial taken with regard to the mean function defines elements of a restricted factor matrix that may include parameters that enter nonlinearly. Similar to factor scores, random coefficients are combined with the factor matrix to produce individual latent curves that need not follow the same form as the mean curve. Here the associations between change characteristics in multiple repeated measures are studied. A factor analysis model for covariates is included as a means of relating latent covariates to the factors characterizing change in different repeated measures. An example is provided.

Sport is important internationally; but in Australia, it is part of the national identity. The enjoyment of public open space for sport is, therefore, an assumed community right. We interviewed key staff from inner Sydney councils about management issues associated with public open space. The greatest concern was sporting fields – formal and informal – which were considered to have exceeded carrying capacity mainly because of the unintended outcomes of government programmes/policies spanning; (1) ‘healthy lifestyles’ which increased public open space use; (2) ‘urban consolidation’ increased inner-city population density with associated increased usage and loss of open space; (3) ‘temporal water restriction’ during drought (not ‘water budgets’) which intensify management issues; and (4) ‘building the education revolution’, meaning that public open space lost from schools results in increased pressure on public open space. Consequences have increased human pressure on public open space without commensurate consideration for the management and/or expansion of these areas. 相似文献

Landscape design is an expression and repository of cultural values and beliefs, and in Aotearoa, New Zealand, the designed landscape faces particular challenges. Globalization is seen as a potential threat to landscape identity, which is even more significant for a country which has built its economy and self-image from its unique natural landscape. The potential for resistance is limited by the small size and youth of the profession of landscape architecture in New Zealand. While traditions of farming and gardening extend back to early European settlement in the mid nineteenth century, and beyond to indigenous Maori practices of land modification, professional landscape design is a relatively recent development (the first tertiary course in landscape architecture began at Lincoln College (now Lincoln University) in 1969). Landscape design in New Zealand draws its vocabulary from the power of the country's natural heritage landscapes, convinced that a naturalistic aesthetic exclusively represents environmental health. Some of the core values of New Zealand society are, however, overlooked by designers. The need to develop a critically informed design language which includes the farming landscape along with the natural one is argued. The invention of such a language, referred to as a complex ecological aesthetic, is seen as a potential source of design expression that is invigorated by the tension between mechanistic and natural landscape aesthetics. It therefore has the potential to promote environmental health, while being regionally grounded, and can help face the challenges that globilization poses to the landscape. 相似文献

ABSTRACT A bifunctional monophosphonic/sulfonic acid ion exchange resin with high capacity has been synthesized. Metal ion studies have been carried out with europium, americium, and ferric nitrate in solutions of varying acidity, with and without sodium nitrate added. The bifunctional resin complexes far higher levels of Eu(III) from 0.5 and 1 N nitric acid than the monofunctional phosphonic acid resin. It is postulated that the sulfonic acid ligand provides an access mechanism for the metal ions into the polymer matrix by hydrating the matrix and preventing its collapse in high ionic strength solutions thus allowing for rapid ionic complexation by the selective phosphonic acid ligands. The bifunctional monophosphonic/sulfonic acid resin has both ligands bound to a polystyrene support. It complexes higher levels of metal ions than a comparable resin differing only by having the monophosphonic acid ligand directly bound to the C-C backbone. Results are compared to a diphosphonic / sulfonic acid resin. 相似文献

Reliable methods are needed to detect total and pathogenic Vibrio parahaemolyticus. One marker of V. parahaemolyticus virulence is the thermostable-related hemolysin. We developed an alkaline phosphatase-labeled DNA probe method for the specific detection and enumeration of trh-positive V. parahaemolyticus by colony hybridization. The probe was tested against a panel of 200 bacterial strains and determined to be specific for trh-positive V. parahaemolyticus. Additionally, the trh alkaline phosphatase probe colony hybridization was successfully used to detect and enumerate trh-positive V. parahaemolyticus in seafood and water samples collected from the United States and the United Kingdom. 相似文献

Responds to R. E. Erard's comments (see record 2009-13007-011) on the current authors' original article (see record 2008-12151-002) which reviewed a number of studies that identified cultural differences in the use and effect of different types of social support among Asians and Asian Americans and European Americans. Essentially, in his comment, Erard denied the validity of research examining cultural differences. The authors strongly believe that the issues concerning within-culture variation do not nullify the importance of conducting research on culturally based psychological and behavioral patterns.
