The SF-36: a simple, effective measure of mobility disability for epidemiological studies
No full textBackgroundMobility disability is a major problem in older people. Numerous scales exist for the measurement of disability but often these do not permit comparisons between study groups. The physical functioning (PF) domain of the established and widely used Short Form-36 (SF-36) questionnaire asks about limitations on ten mobility activities.ObjectivesTo describe prevalence of mobility disability in an elderly population, investigate the validity of the SF-36 PF score as a measure of mobility disability, and to establish age and sex specific norms for the PF score.MethodsWe explored relationships between the SF-36 PF score and objectively measured physical performance variables among 349 men and 280 women, 59-72 years of age, who participated in the Hertfordshire Cohort Study (HCS). Normative data were derived from the Health Survey for England (HSE) 1996.Results32% of men and 46% of women had at least some limitation in PF scale items. Poor SF-36 PF scores (lowest fifth of the gender-specific distribution) were related to: lower grip strength; longer timed-up-and-go, 3m walk, and chair rises test times in men and women; and lower quadriceps peak torque in women but not men. HSE normative data showed that median PF scores declined with increasing age in men and women.ConclusionOur results are consistent with the SF-36 PF score being a valid measure of mobility disability in epidemiological studies. This approach might be a first step towards enabling simple comparisons of prevalence of mobility disability between different studies of older people. The SF-36 PF score could usefully complement existing detailed schemes for classification of disability and it now requires validation against them
Dispelling the Misconceptions Raised by the Davis Dissent
No full textThe Supreme Court, in Davis v. Monroe County Board of Education, correctly held school districts liable under Title IX for deliberate indifference to known instances of student-on-student sexual harassment that is so severe, pervasive and objectively offensive that it effectively bars the victim\u27s access to an educational opportunity or benefit. Professor Schaffner argues, however, that the majority failed to adequately address three concerns raised by the Davis dissent, that: (1) as a matter of federalism, this issue should be left to the states; (2) student peer sexual harassment does not constitute sex discrimination and (3) holding schools liable for student peer sexual harassment will place schools in a bind between protecting the harassed and infringing on the First Amendment rights of the harasser. Professor Schaffner addresses these concerns, stating first that the majority decision is consistent with traditional federalism principles designed to allocate power between the states and the federal government such that the nation may reap the benefits of interstate diversity and national uniformity. The equal protection of the sexes is a national principle which requires uniform federal enforcement. Second, theoretical models that justify sexual harassment as a form of sex discrimination in the workplace apply to student peer sexual harassment in schools and demonstrate that actionable student peer sexual harassment under Title IX constitutes sex discrimination. Third, by limiting actionable sexual harassment to that which effectively bars a victim\u27s access to an educational opportunity, the Court remains consistent with its First Amendment jurisprudence that allows schools to prohibit speech that causes a substantial disruption to the educational environment, thus steering clear of infringing on the harasser\u27s First Amendment rights
SF Gospel: Blog contents, 2006-2015
No full textSF Gospel (2006-2015) was a blog exploring religious and theological themes in science fiction and popular culture by Gabriel Mckee, author of The Gospel According to Science Fiction. The primary PDF contains the textual content of the blog, along with most images that accompanied the original posts. The appendix PDF contains guest posts written by Mckee for other blogs and websites (including SF Signal, Holy Heroes, Nerve.com, and Religion Dispatches) during the course of SF Gospel's existence

Systematic investigation of gastrointestinal diseases in China (SILC): validation of survey methodology
No full textBackground: Symptom-based surveys suggest that the prevalence of gastrointestinal diseases is lower in China than in Western countries. The aim of this study was to validate a methodology for the epidemiological investigation of gastrointestinal symptoms and endoscopic findings in China. Methods: A randomized, stratified, multi-stage sampling methodology was used to select 18 000 adults aged 18-80 years from Shanghai, Beijing, Xi'an, Wuhan and Guangzhou. Participants from Shanghai were invited to provide blood samples and undergo upper gastrointestinal endoscopy. All participants completed Chinese versions of the Reflux Disease Questionnaire (RDQ) and the modified Rome II questionnaire; 20% were also invited to complete the 36-item Short Form Health Survey (SF-36) and Epworth Sleepiness Scale (ESS). The psychometric properties of the questionnaires were evaluated statistically. Results: The study was completed by 16 091 individuals (response rate: 89.4%), with 3219 (89.4% of those invited) completing the SF-36 and ESS. All 3153 participants in Shanghai provided blood samples and 1030 (32.7%) underwent endoscopy. Cronbach's alpha coefficients were 0.89, 0.89, 0.80 and 0.91, respectively, for the RDQ, modified Rome II questionnaire, ESS and SF-36, supporting internal consistency. Factor analysis supported construct validity of all questionnaire dimensions except SF-36 psychosocial dimensions. Conclusion: This population-based study has great potential to characterize the relationship between gastrointestinal symptoms and endoscopic findings in China.Xiaoyan Yan, Rui Wang, Yanfang Zhao, Xiuqiang Ma, Jiqian Fang, Hong Yan, Xiaoping Kang, Ping Yin, Yuantao Hao, Qiang Li, John Dent, Joseph Sung, Duowu Zou, Saga Johansson, Katarina Halling, Wenbin Liu and Jia H
RESIDUAL SOLUBILITY OF SF-GROUPS
No full textSeifert Fibre Groups (SF-Gps) have been introduced and their first derived groups have been worked out in an earlier paper by the author [2,3]. Now we aim to prove that they are residually soluble and residually finite
The Author, the IRS and Prepublication Expenditures
No full textAuthors have customarily deducted expenditures incurred in preparing a book for publication. The IRS has taken the position that such expenditures should be capitalized and then amortized. In the recent case of Faura v. Commissioner, the Tax Court allowed authors to deduct prepublication expenditures rather than capitalize them. In 1976, section 280 was added to the Internal Revenue Code by the 1976 Tax Reform Act. This section appears to require authors to capitalize prepublication expenditures for books. The Tax Reform Act of 1976 also contained section 2119 which allows authors to deduct prepublication expenditures until regulations are promulgated concerning them. To date, there is no solid authority on whether an author should capitalize post-1976 prepublication expenditures
Can a Computer be an Author - Copyright Aspects of Artificial Intelligence
No full textThis note discusses the impact of current advances in computer science upon traditional copyright notions of authorship and originality. Finding that certain works created largely by computer are outside the ambit of federal copyright law, yet in need of protection for traditional policy reasons, the author explores several alternatives for providing copyright protection. A solution is proposed wherein the court presumes human authorship in machine created works, then, after ascertaining that the work meets the other requirements of federal copyright law, determines which individual is most deserving of copyright ownership
