Combining GPS, GIS, and accelerometry to explore the physical activity and environment relationship in children and young people – a review

The environment has long been associated with physical activity engagement, and recent developments in technology have resulted in the ability to objectively quantify activity behaviours and activity context. This paper reviews studies that have combined Global Positioning Systems (GPS), Geographic Information Systems (GIS) and accelerometry to investigate the PA-environment relationship in children and young people (5–18 years old). Literature searches of the following bibliographic databases were undertaken: Sportdiscus, Medline, Embase, CINAHL, Psychinfo and Applied Social Sciences Index and Abstracts (ASSIA). Fourteen studies met the inclusion criteria, and covered topics including greenspace use, general land use, active travel, and the built environment. Studies were largely cross-sectional and took place across developed countries (UK, USA, Canada, New Zealand, and Australia). Findings suggest that roads and streets, school grounds, and the home location are important locations for total PA, and moderate to vigorous PA (MVPA). The relationship between greenspace was positive, however, multiple definitions and outcome measures add complexity to the results. MVPA was more likely in those exposed to higher levels of greenspace compared to sedentary individuals. Total MVPA time in greenspace is low, but when framed as a proportion of the total can be quite high. Domestic gardens may be an important area for higher intensity activity.<p></p> Researchers are encouraged to show transparency in their methods. As a relatively new area of research, with ever-evolving technology, future work is best placed in developing novel, but robust, methods to investigate the PA and environment relationship. Further descriptive work is encouraged to build on a small but increasing knowledge base; however, longitudinal studies incorporating seasonal/weather variation would also be extremely beneficial to elicit some of the nuances associated with land use. A greater understanding of geographic variation (i.e. within and between countries), as well as urban/suburban and rural dwelling is welcomed, and future work should also include the investigation of psycho-social health as an outcome, as well as differences in socio-economic status, sex and adiposity

Exploring the relationship between groundwater geochemical factors and denitrification potentials on a dairy farm in southeast Ireland

Changes resulting from the publishing process, such as peer review, editing, corrections, structural formatting, and other quality control mechanisms may not be reflected in this document. Changes may have been made to this work since it was submitted for publication. A definitive version was subsequently published in Ecological Engineering, volume 37, issue 9, September 2011, 1304-1313. DOI: 10.1016/j.ecoleng.2011.03.025peer-reviewedNitrate (NO3−) loss from agriculture to shallow groundwater and transferral to sensitive aquatic ecosystems is of global concern. Denitrifying bioreactor technology, where a solid carbon (C) reactive media intercepts contaminated groundwater, has been successfully used to convert NO3− to di-nitrogen (N2) gas. One of the challenges of groundwater remediation research is how to track denitrification potential spatially and temporally within reactive media and subsoil. First, using δ15N/δ18O isotopes, eight wells were divided into indicative transformational processes of ‘nitrification’ or ‘denitrification’ wells. Then, using N2/argon (Ar) ratios these wells were divided into ‘low denitrification potential’ or high denitrification potential’ categories. Secondly, using falling head tests, the saturated hydraulic conductivity (Ksat) in each well was estimated, creating two groups of ‘slow’ (0.06 m day−1) and ‘fast’ (0.13 m day−1) wells, respectively. Thirdly, two ‘low denitrification potential’ wells (one fast and one slow) with high NO3− concentration were amended with woodchip to enhance denitrification. Water samples were retrieved from all wells using a low flow syringe to avoid de-gassing and analysed for N2/Ar ratio using membrane inlet mass spectrometry. Results showed that there was good agreement between isotope and chemical (N2/Ar ratio and dissolved organic C (DOC)) and physio-chemical (dissolved oxygen, temperature, conductivity and pH) parameters. To explain the spatial and temporal distribution of NO3− and other parameters on site, the development of predictive models using the available datasets for this field site was examined for NO3−, Cl−, N2/Ar and DOC. Initial statistical analysis was directed towards the testing of the effect of woodchip amendment. The analysis was formulated as a repeated measures analysis of the factorial structure for treatment and time. Nitrate concentrations were related to Ksat and water level (p < 0.0001 and p = 0.02, respectively), but did not respond to woodchip addition (p = 0.09). This non-destructive technique allows elucidation of denitrification potential over time and could be used in denitrifying bioreactor technology to assess denitrification hotspots in reactive media, while developing a NO3− spatial and temporal predictive model for bioreactor site specific conditions

Alcohol in fatal road crashes in Ireland 2003 to 2005.

Alcohol has been recognised as a major factor in road crashes. However, no official data are provided in Ireland to indicate what proportion of the deaths on Irish roads has alcohol as a contributory factor. Irish drivers do drink alcohol and drive. A study on fatal crashes in 2003 showed that over a third of fatal crashes were alcohol related. The aim of this study was to build on the data for 2003 and provide information on the extent of the relationship between drink driving and fatal crashes in 2004 and 2005

THE PERFORMANCE OF LEADERSHIP: ALL THE SCHOOL’S A STAGE AND THE TEACHERS AND STUDENTS ARE MERELY PLAYERS

The purpose of this qualitative case study was to identify and better understand the performance qualities that are prevalent in successful principals. Specifically, acting and leadership tools previously identified and compared by Dunklee (2000) were used to gain a better understanding of the interview process utilized to hire K-12 principals in school districts with more than 10,000 students in the state of Indiana. Arguably, the roles of the principal are much like those of an actor who must think on his or her feet in multiple situations. It is hoped that this study contributes new knowledge to assist in the selection process of principals and help in developing an interview framework to use in identifying and hiring the most effective principals by acknowledging and capitalizing on performance qualities. The following research questions framed the interviews with practicing hiring managers: 1. In what ways does acting like an effective school principal, as understood through performance qualities, result in being an effective principal? 2. What performance qualities do hiring managers perceive their successful principals utilize? A case study methodology was selected to take a more in depth look into the hiring process in five large urban school systems in Indiana. A variety of demographic data were collected about the individual school systems, with a key focus on the interview process and desirable attributes for hiring principals. The major themes and subthemes were also identified. Primary themes include the following: (a) Hiring protocols are not focused on performance qualities, (b) Performance qualities were predetermined to inform the interview process, and, (c) Districts supported professional development for both aspiring and practicing principals. The primary theme of hiring protocols included the subthemes of (a) The use of a cattlecall approach (i.e., mass interviewing) in the interview process are consistent in all districts included in the study, (b) The practice of hiring internal candidates is a prevalent practice, and (c) Current interview rubrics and questions to identify effective principals. The primary theme of nine performance qualities were maintained as subthemes in this category and later reduced in number. The primary theme of training for aspiring and practicing principals led to the subthemes of (a) Internal and (b) External use of those professional development practices

Hew Lorimer : a special kind of artist

This thesis seeks firstly to provide an overview of the life and work of the Scottish sculptor and craftsman, Hew Lorimer, and secondly to discuss some issues concerning contemporary craft, and the significance this has for museums and galleries. Part one includes a chronological survey of the life and achievements of the sculptor, a comprehensive catalogue of his work and an inventory of his studio at the time of his death. It is intended to provide a body of detailed information which can be used as a work of reference in the future. Leading on from certain issues raised in the first section, there follows a general discussion regarding the distinctions that are commonly made between art and craft, centred around the themes of individuality, skill, function and economics. It is hoped to raise questions concerning the way certain objects are labelled and evaluated, and relates to the discussion of museum and gallery display. The final part of the thesis involves a comparative study of several museums and galleries with the aim of examining methods of display, interpretation and collecting, with particular reference to contemporary crafts

Exploring the Role of Playfulness, Social Support and Self Esteem in Coping with the Transition to Motherhood

First time parenthood is a major transition in the lives of many young adults, and can lead to both positive and negative outcomes in terms of marital satisfaction and individual adjustment. New mothers are particularly at risk for declines in satisfaction and adjustment as they are often the primary caregivers. The current study examined the coping processes of 197 women in their first year of motherhood. Playfulness, social support and self esteem were examined as possible personal resources during this transition. Data were collected using a web based survey and analyzed with cluster and correlational analyses. Results suggested postpartum adjustment is unrelated to relationship satisfaction. Additionally, while the variables of interest, particularly playfulness, predicted a large amount of variance in relationship satisfaction, they only predicted a small amount of variance in postpartum adjustment. These findings will help counseling psychologists develop and implement interventions to help new mothers in this transition

France, Italy and the 2002/2003 Iraq crisis

France opposed the US-led intervention in Iraq in March 2003 while Italy supported it. Domestic dynamics, including popular opinion and growing concern for Muslim sentiment, exerted a secondary influence on those decisions. Other factors that influenced the leaders of France and Italy to take opposing stances on the prospective intervention included security and threat assessments. Discord in US-French relations was exacerbated by disagreements over other international issues, especially the role of the UN Security Council. This thesis assesses the relative weight of these various factors in the French and Italian decisions, and examines the interplay of the key national decisions made by American, French and Italian leaders. The thesis concludes that French and Italian decisions were influenced by factors in addition to the issues in question-that is, whether the Iraqi regime had complied with the UN Security Council resolutions calling for the elimination of weapons of mass destruction and certain delivery means and, if not, whether the use of force was an appropriate and justified course of action. It also concludes that the severe damage to US-French relations may be overcome as Paris and Washington cooperate in meeting international security responsibilities. The European Union's Common Foreign and Security Policy may face greater challenges, owing to the significant intra-EU differences revealed during the Iraq crisis.http://archive.org/details/franceitalyndira109451435Major, United States Air ForceApproved for public release; distribution is unlimited

Investigating the relationship between HIV testing and risk behaviour in Britain: National Survey of Sexual Attitudes and Lifestyles 2000.

OBJECTIVES: To estimate the prevalence of, and identify factors associated with, HIV testing in Britain. DESIGN: A large, stratified probability sample survey of sexual attitudes and lifestyles. METHODS: A total of 12,110 16-44 year olds completed a computer-assisted face-to-face interview and self-interview. Self-reports of HIV testing, i.e. the timing, reasons for and location of testing, were included. RESULTS: A total of 32.4% of men and 31.7% of women reported ever having had an HIV test, the majority of whom were tested through blood donation. When screening for blood donation and pregnancy were excluded, 9.0% of men and 4.6% of women had had a voluntary confidential HIV test (VCT) in the past 5 years. However, one third of injecting drug users and men who have sex with men had a VCT in the past 5 years. VCT in the past 5 years was significantly associated with age, residence, ethnicity, self-perceived HIV risk, reporting greater numbers of sexual partners, new sexual partners from abroad, previous sexually transmitted infection diagnosis, and injecting non-prescribed drugs for men and women, and same-sex partners (men only). Whereas sexually transmitted disease clinics were important sites for VCT, general practice accounted for almost a quarter of VCT. CONCLUSION: HIV testing is relatively common in Britain; however, it remains largely associated with population-based blood donation and antenatal screening programmes. In contrast, VCT remains highly associated with high-risk (sexual or drug-injecting) behaviours or population sub-groups at high risk. Strategies to reduce undiagnosed prevalent HIV infection will require further normalization and wider uptake of HIV testing

Registration in the Danish Regional Nonmelanoma Skin Cancer Dermatology Database: completeness of registration and accuracy of key variables

Anna L Lamberg1, Deirdre Cronin-Fenton2, Anne B Olesen11Department of Dermatology, 2Department of Clinical Epidemiology, Aarhus University Hospital, Aarhus, C, DenmarkObjective: To validate a clinical database for nonmelanoma skin cancer (NMSC) with the aim of monitoring and predicting the prognosis of NMSC treated by dermatologists in clinics in the central and north Denmark regions.Methods: We assessed the completeness of registration of patients and follow-up visits, and positive predictive value (PPV), negative predictive value (NPV), sensitivity, and specificity of registrations in the database. We used the Danish Pathology Registry (DPR) (n = 288) and a review of randomly selected medical records (n = 67) from two clinics as gold standards.Results: The completeness of registration of patients was 62% and 76% with DPR and medical record review as gold standards, respectively. The completeness of registration of 1st and 2nd follow up visits was 85% and 69%, respectively. The PPV and NPV ranged from 85% to 99%, and the sensitivity and specificity from 67% to 100%.Conclusion: Overall, the accuracy of variables registered in the NMSC database was satisfactory but completeness of patient registration and follow-up visits were modest. The NMSC database is a potentially valuable tool for monitoring and facilitating improvement of NMSC treatment in dermatology clinics. However, there is still room for improvement of registration of both patients and their follow-up visits.Keywords: nonmelanoma skin cancer, validation, database, positive predictive value, completenes

Increasing prevalence of male homosexual partnerships and practices in Britain 1990-2000: evidence from national probability surveys.

OBJECTIVES: To estimate the prevalence and timing of homosexual experience among British men; to explore the patterns of sexual practices and partnerships in 2000, and behavioural and attitudinal changes between 1990 and 2000 among men who have sex with men (MSM). DESIGN: Two large, stratified probability sample surveys of the general population. METHODS: Trained interviewers administered a combination of face-to-face and self-completion questionnaires to men aged 16 to 44 years resident in Britain (n = 6000 in 1990 and n = 4762 in 2000). RESULTS: In 2000, 2.8% of British men reported sex with men in the past 5 years. 46.0% of MSM reported five or more partners in the past 5 years, and 59.8% reported unprotected anal intercourse in the past year. A total of 33.0% of MSM reported one or more female partner(s) in the past year. In comparison with 1990, there was a significant increase in the proportion of MSM in the population in 2000, and among these men, in the proportion reporting receptive anal intercourse in the past year [age-adjusted odds ratio (OR), 2.08; 95% confidence interval (CI), 1.08-4.00], but no significant change in self-perceived HIV-risk (age-adjusted OR, 1.11; 95% CI, 0.49-2.51) or HIV testing in past 5 years (age-adjusted OR, 1.14; 95% CI, 0.57-2.25). CONCLUSIONS: Evidence of increasing prevalence of homosexual intercourse among the British male population coupled with increases in some HIV-risk behaviours among MSM suggests overall increasing numbers at risk in the population. Although these changes may partly reflect an increased willingness to report these behaviours, our results are consistent with increasing incidence of sexually transmitted infections and behavioural surveillance data
