Factors in the length of stay of homeless families in temporary accommodation

Data relating to 526 homeless families in temporary accommodation were collected in a study directed mainly to the examination of support networks of a sample of these families. The data, however, have allowed the authors to examine the effects of certain characteristics of these families on the average length of stay in temporary accommodation before they were housed permanently. Log-linear analysis was used to establish the independent effect of various attributes available from the data. In general the feature which seemed to influence the length of stay most was the time of the year when the family was admitted into temporary accommodation followed by the sort of reason the families gave for being homeless at the time of admission. Those who had been illegally evicted tended to take longer to be rehoused whilst those with rental or tenant difficulties took less time to be rehoused. The authors are then able to produce profiles based on this analysis of those families which are likely to stay longest in temporary accommodation as against those likely to stay the shortest time.

This note discusses a problem appropriate for a beginning mathematical statistics course. Four estimators of the standard deviation of a normal data source are compared using mean square error. Both the uniformly minimum variance unbiased estimator and the usual estimator are found to be inadmissible.     

A Quantitative Assessment of the Prion Risk Associated with Wastewater from Carcass‐Handling Facilities

Wastewater from facilities processing livestock that may harbor transmissible spongiform encephalopathies (TSEs) infectivity is permitted under license for application to land where susceptible livestock may have access. Several previous risk assessments have investigated the risk of bovine spongiform encephalopathy (BSE) associated with wastewater effluents; however, the risk of exposure to classical scrapie and atypical scrapie has not been assessed. With the prevalence of certain TSEs (BSE in cattle and classical scrapie in sheep) steadily in decline, and with considerable changes in the structure of carcass‐processing industries in Great Britain, a reappraisal of the TSE risk posed by wastewater is required. Our results indicate that the predicted number of new TSE infections arising from the spreading of wastewater on pasture over one year would be low, with a mean of one infection every 1,000 years for BSE in cattle (769, 555,556), and one infection every 30 years (16, 2,500), and 33 years (16, 3,333) for classical and atypical scrapie, respectively. It is assumed that the values and assumptions used in this risk assessment remain constant. For BSE in cattle the main contributors are abattoir and rendering effluent, contributing 35% and 22% of the total number of new BSE infections. For TSEs in sheep, effluent from small incinerators and rendering plants are the major contributors (on average 32% and 31% of the total number of new classical scrapie and atypical scrapie infections). This is a reflection of the volume of carcass material and Category 1 material flow through such facilities.     

Exercise Motivation of College Students in Online,Face-to-Face,and Blended Basic Studies Physical Activity and Wellness Course Delivery Formats

Abstract

Objective: The purpose of this study was to assess exercise motivation among college students self-selected into 4 online (OL) and face-to-face (F2F) basic studies’ physical activity and wellness course delivery formats. Participants/Methods: Out of 1,037 enrolled students during the Spring 2009 semester, 602 responded online to demographic questions and to the Behavioural Regulation in Exercise Questionnaire, which assessed exercise motivation on 5 subscales. Results: There were no significant differences (p > .05) in exercise motivation for students across course delivery formats, but there was a significant difference in age and employment status between the completely OL and F2F course formats. Conclusions: Health and physical educators can utilize these findings to better understand that physical activity and wellness students are not necessarily trying to avoid physical activity when selecting the OL course format, but are more likely trying to balance work and school responsibilities and need greater flexibility in time and location.     

Infant Attention to Dynamic Audiovisual Stimuli: Look Duration From 3 to 9 Months of Age

The goal of this study was to examine developmental change in visual attention to dynamic visual and audiovisual stimuli in 3‐, 6‐, and 9‐month‐old infants. Infant look duration was measured during exposure to dynamic geometric patterns and Sesame Street video clips under three different stimulus modality conditions: unimodal visual, synchronous audiovisual, and asynchronous audiovisual. Infants looked longer toward Sesame Street stimuli than geometric patterns, and infants also looked longer during multimodal audiovisual (synchronous and asynchronous) presentations than during unimodal visual presentations. There was a three‐way interaction of age, stimulus type, and stimulus modality. Significant differences were found within and between age groups related to stimulus modality (visual or audiovisual) while viewing Sesame Street clips. No significant interaction was found between age and stimulus type while infants viewed dynamic geometric patterns. These findings indicate that patterns of developmental change in infant attention vary based on stimulus complexity and modality of presentation.     

Beyond Performance Enhancement: Polypharmacy among Collegiate Users of Steroids

Abstract

The extremely low prevalence of steroid use among college students makes it virtually impossible to conduct analyses on any single college campus. By studying a cohort of 58,625 college students from 78 institutions that administered the Core Alcohol and Drug Survey in 1990 and 1991, a critical mass of 175 users on which it was possible to conduct statistical analyses was identified. Compared with a randomly selected group of nonusers, the steroid users reported consuming dramatically more alcohol and demonstrated higher rates of binge drinking. In addition, a significantly higher percentage of steroid users reported using tobacco, marijuana, cocaine, amphetamines, sedatives, hallucinogens, opiates, inhalants, and designer drugs. A higher percentage of steroid users than nonusers also reported experiencing negative consequences as a result of substance abuse, and a greater percentage of the steroid users reported family histories of abuse of alcohol and other drugs. Implications from the standpoint of student development are discussed.     

‘Without Being Walt Whitman’: Vicente Huidobro,Whitman, and the Poetics of Sight

The Chilean vanguardista poet Vicente Huidobro singlehandedly inaugurated the Spanish-language avant-gardes with his 1918 poem Ecuatorial [Equatorial], and remained a dynamic and controversial global figure until his death in 1948. This essay demonstrates how Huidobro appropriated Walt Whitman’s ‘Salut au Monde’ into this inaugural poem, taking from the US poet an elevated, comprehensive poetics of sight. But Whitman’s all-seeing aesthetic seriously threatened Huidobro’s own ethics and avant-garde poetic philosophy — Creationism — leading the Chilean to reject Whitman and this poetic vision in his 1931 Altazor. If Whitman’s poetic speaker could ‘contain multitudes’, seeing the whole world in instant juxtaposition, Huidobro’s ideal Creationist poet must instead empty himself, to create anew. Finally, this textual and historical confrontation reveals not only how Whitman brought his unifying vision to bear on his nation’s Civil War, but also how the aging Huidobro, facing World War II and the imperialist shadow of the US, wrote back to Whitman to qualify and clarify what this vision might mean for ‘America’.
