Real estate agents, brochure and misleading or deceptive conduct

The decision of the High Court in Butcher v Lachlan Elder Realty Pty Ltd [2004] HCA 60 involves issues that affect every person who is induced to buy real estate in Australia by statements in sales brochures distributed by real estate agents. One of these issues is the extent to which estate agents unwittingly engage in misleading or deceptive conduct under s 52 of the Trade Practices Act 1974 (Cth) (‘the Act’) when they distribute sales brochures that contain untrue or misleading statements prepared by others. A further issue is the extent to which agents can escape liability by relying on disclaimers about the authenticity of false statements contained in brochures prepared by them.

Uso de materiales no tradicionales en el proceso creativo artístico : aplicaciones a la enseñanza.

Analizar el movimiento Art Brut o Outsider Art desde el punto de vista del uso de la materia y estudiar su aplicación en el aula. Alumnos de cinco años que cursan Educación Infantil en un colegio público de Madrid. En primer lugar, se estudia a varios representantes del movimiento Outsider, que son autores ajenos al mundo artístico y sin formación académica. Se analizan los materiales que emplean y sus procesos creativos. Además, se dan a conocer algunos escritos de Jean Dubuffet, principal exponente del movimiento. Por último, se describe una experiencia en el aula en la que se aplican los principios del movimiento Outsider a través de diez unidades didácticas. Se utilizan como fuentes de información el personal y las colecciones bibliográficas y artísticas de varias instituciones, galerías y museos. Entre todas ellas, destaca la Biblioteca de la Colección Art Brut de Lausanne. Además, para la realización de la experiencia con los alumnos de Educación Infantil se usan materiales de dibujo, pintura y manualidades. Se utiliza una metodología activa, en la que se da más importancia al proceso creativo que a los resultados. Se confirma la hipótesis sobre la posibilidad de adaptar los procesos y usos de la materia del movimiento Outsider a la escuela española, con el fin de trabajar la creatividad. Las actividades, que resultan divertidas para los niños, contribuyen a reforzar su confianza y autoestima. También se fomenta la curiosidad y la constancia y dedicación de los alumnos en sus tareas. Se aportan nuevos procesos creativos para la educación artística, en los que se utilizan materiales no tradicionales.

Photophysical properties and interactions of xanthene dyes in aqueous micelles

Photosensitizers (PS) photodynamic activities are regulated by their location in the biological target, which modulates their photophysical and photochemical features. In this work the PS partition for the Xanthene Dyes Fluorescein (FSC), Eosin Y(EOS), Erythrosin B (ERY) and Rose Bengal B (RBB) in biomimetic models (SDS, CTAB and Pluronic P-123 micelles) and the effects on their photophysical characteristics are evaluated. The hydrophobic and electrostatic forces that govern the PS-micelle interaction are analyzed. At physiological pH (7.25), the ability of the dianionic protolytic form of the dyes to be positioned into the micelle palisade and its micelle interaction depends not only on the hydrophobicity of the dye but also on the micellar surface charge. The Binding Constants obey exactly the same order of the Partition Coefficients for the dyes in P-123 and CTAB micelles. The Stern-Volmer treatment pointed out that dyes are located inside the micelle, especially ERY and RBB. The magnitude of the dye-micelle interaction increased from SDS, P-123 and finally CTAB micelles due to the charges between dye and micelle, and among the xanthenes, their hydrophobic characteristics. Within the micelle pseudo phase, ERY and RBB are still very efficient photosensitizers exhibiting high quantum yield of singlet oxygen, which turns them very attractive especially with P-123 polymeric system as drug delivery systems in photodynamic therapy.

The HeartQoL: Part II. Validation of a new core health-related quality of life questionnaire for patients with ischemic heart disease

Background: Evaluation of health-related quality of life (HRQL) is important in improving the quality of patient care. The aim of this study was to determine the psychometric properties of the HeartQoL in patients with ischemic heart disease (IHD), specifically angina, myocardial infarction (MI), or ischemic heart failure. Methods: Data for the interim validation of the HeartQoL questionnaire were collected in (a) a cross-sectional survey and (b) a prospective substudy of patients undergoing either a percutaneous coronary intervention (PCI) or referred to cardiac rehabilitation (CR) and were then analyzed to determine the reliability, validity, and responsiveness of the HeartQoL questionnaire. Results: We enrolled 6384 patients (angina, n = 2111, 33.1%; MI, n = 2351, 36.8%; heart failure, n = 1922, 30.1%) across 22 countries speaking 15 languages in the cross-sectional study and 730 patients with IHD in the prospective substudy. The HeartQoL questionnaire comprises 14-items with physical and emotional subscales and a global score (range 0–3 (poor to better HRQL). Cronbach’s α was consistently ≥0.80; convergent validity correlations between similar HeartQoL and SF-36 subscales were significant (r ≥ 0.60, p < 0.001); discriminative validity was confirmed with predictor variables: health transition, anxiety, depression, and functional status. HeartQoL score changes following either PCI or CR were significant (p < 0.001) with effect sizes ranging from 0.37–0.64. Conclusion: The HeartQoL questionnaire is reliable, valid, and responsive to change allowing clinicians and researchers to (a) assess baseline HRQL, (b) make between-diagnosis comparisons of HRQL, and (c) evaluate change in HRQL in patients with angina, MI, or heart failure with a single IHD-specific HRQL instrument.
