How do variations in Urban Heat Islands in space and time influence household water use? The case of Phoenix, Arizona
No full textabstract: This paper explores how urbanization, through its role in the evolution of Urban Heat Island (UHI), affects residential water consumption. Using longitudinal data and drawing on a mesoscale atmospheric model, we examine how variations in surface temperature at the census tract level have affected water use in single family residences in Phoenix, Arizona. Results show that each Fahrenheit rise in nighttime temperature increases water consumption by 1.4%. This temperature effect is found to vary significantly with lot size and pool size. The study provides insights into the links between urban form and water use, through the dynamics of UHI.Corresponding Author:

Are P values given more importance than they deserve?
No full textIn many of the scientific reports, the conclusions are based on the P values. The results are dichotomized based on the cutoff of P values. Often, the clinical significance is ignored over statistical significance. The sole dependence on P values can lead to erroneous conclusions. The confidence intervals in turn can provide more useful information. They provide applicability of the data in whole populations. This article provides insight into P values, the null hypothesis, and confidence intervals

Prevalence of testosterone deficiency in elderly male and its association with frailty and mobility at a tertiary care centre
No full textBackground and Objectives: Several cross-sectional and prospective longitudinal studies have shown a progressive decline in Serum (S) Testosterone levels with an increase in age. The clinical consequence of this decline in S Testosterone is not clear from the prevailing data. Several ageing features like decreased libido, Osteo-sarcopenia, anemia, and depressed mood may be associated with reduced androgen levels in elderly males. This study was aimed to study the prevalence of androgen deficiency in elderly males more than 60 years of age presenting to the outpatient department of a tertiary care hospital and its association with frailty and mobility. Methods: A cross-sectional observational study was conducted over two years at a tertiary care hospital in Pune, India. The participants underwent a detailed history and physical examination. Biochemical tests and S total testosterone estimation was done. Mobility was estimated by calculating the time taken to perform the Timed Up and Go test (TUGT). Frailty was calculated by Fried's frailty index. Data are presented as mean ± standard deviation, and a comparison between the groups was made using Mann–Whitney U-test. The categorical variables are presented in frequencies along with respective percentages and were compared using the Chi-square or Fisher's exact test. The data was analyzed using SPSS version 22. A P <.05 was considered statistically significant in all the tests. Results: The mean age of the study participants was 68.37 ± 6.3 years, with a range of 60-88 years. The mean S total testosterone levels were 3.95 ± 2.06 ng/ml with a range of 0.04–25.36 ng/ml. As per the study definition, Ninety-two (21.67%) participants had testosterone deficiency. Three hundred and thirty-three (78.5%) participants had impaired motility represented by a TUGT time of more than 12 seconds. The Frailty index calculated revealed 94 (22.2%) of the study participants to be normal, 263 (62%) to be vulnerable, and 67 (15.8%) of the patients to be frail. Conclusion: The prevalence of testosterone deficiency in the elderly male population was 21.67%. However, there was no association of testosterone deficiency with frailty or impaired mobility. Furthermore, testosterone deficiency was not associated with BMI and hemoglobin levels. In the elderly, testosterone deficiency is associated with low bone mass and therefore imply an increased risk of osteoporotic fractures
Decoding "Public authority" under the RTI act: a comment on Subhash Chandra Aggarwal v. Indian national congress
No full textThe June, 2013 order of the Central Information Commission ("CIC") in Subhash Chandra Aggarwal v. Indian National Congress which brought political parties within the scope of the Right to Information ("RTI") Act, has highlighted some issues regarding the drafting and interpretation of the RTI Act. The CIC held that the six national political parties which were respondents
in the case, have the ingredients that qualify them as "public authorities" within the meaning of section 2(h) of the RTI Act. In this comment the author argues that the reasoning for holding what constitutes substantial financing that makes a body a "public authority" is not clear and the interpretation of the definition of "public authority" is inconsisten
