Study 1: Participants in the Institutions by Artists Convention Report

Recent years have seen rapid growth in artistic activities using quasi-institutional terminology and procedures. Words like “Centre”, “Institute”, “Laboratory”, and “Office” figure prominently in the names of artist-initiated entities. What accounts for the impulse to project agency and authorship through an impersonal entity rather than through the figure of the individual artist? To examine this tendency, the Artifact Institute developed Study 1: Participants in the Institutions by Artists Convention.   The project includes the administration of a survey, analysis of the data collected, and the production of a report. The target group surveyed is defined as the set of all individuals who registered for, presented at, or otherwise attended the Convention. These individuals were invited to complete a questionnaire available at on-site computer terminals for the duration of the Convention and also online. Study 1 uses standard survey methodology and adheres to generally accepted protocols for quantitative research

Gender and respiratory factors associated with dyspnea in chronic obstructive pulmonary disease

RATIONALE: We had shown that COPD women expressed more dyspnea than men for the same degree of airway obstruction. OBJECTIVES: Evaluate gender differences in respiratory factors associated with dyspnea in COPD patients. METHODS: In a FEV(1 )% matched population of 100 men and women with COPD we measured: age, MMRC, FEV(1), FVC, TLC, IC/TLC, PaO(2), PaCO(2), D(LCO), P(imax), P(0.1), Ti/Ttot, BMI, ffmi, 6MWD and VAS scale before and after the test, the Charlson score and the SGRQ. We estimated the association between these parameters and MMRC scores. Multivariate analysis determined the independent strength of those associations. RESULTS: MMRC correlated with: BMI (men:-0.29, p = 0.04; women:-0.28, p = 0.05), ffmi (men:-0.39, p = 0.01), FEV(1 )% (men:-0.64, p < 0.001; women:-0.29, p = 0.04), FVC % (men:-0.45, p = 0.001; women:-0.33, p = 0.02), IC/TLC (men:-0.52, p < 0.001; women: -0.27, p = 0.05), PaO(2 )(men:-0.59, p < 0.001), PaCO(2 )(men:0.27, p = 0.05), D(LCO )(men:-0.54, p < 0.001), P(0.1)/P(imax )(men:0.46, p = 0.002; women:0.47, p = 0.005), dyspnea measured with the Visual Analog Scale before (men:0.37, p = 0.04; women:0.52, p = 0.004) and after 6MWD (men:0.52, p = 0.002; women:0.48, p = 0.004) and SGRQ total (men:0.50, p < 0.001; women:0.59, p < 0.001). Regression analysis showed that P(0.1)/P(imax )in women (r(2 )= 0.30) and BMI, DL(CO), PaO(2 )and P(0.1)/P(imax )in men (r(2 )= 0.81) were the strongest predictors of MMRC scores. CONCLUSION: In mild to severe COPD patients attending a pulmonary clinic, P(0.1)/P(imax )was the unique predictor of MMRC scores only in women. Respiratory factors explain most of the variations of MMRC scores in men but not in women. Factors other than the respiratory ones should be included in the evaluation of dyspnea in women with COPD
