Draws and Drawbacks of an Oxford Study Abroad Experience

Using qualitative research methodology, we interviewed 23 American students participating in a study abroad program at Oxford University in the U.K. Results showed four primary draws to participating in the study abroad program and two perceived drawbacks. Positively, Oxford’s first appealing dynamic related to the tutorial system and students’ expanded range of options for specialized topics as well as in-depth study. Next, participants highly valued Oxford’s academic rigor, which accompanied the university’s unique approach to education. Third, Oxford’s location in England appealed to our participants. Finally, students reported hopes that future benefits would result from their decisions to attend Oxford and perceived associations with Oxford’s prestige. As participants weighed these benefits of studying at OU, they contrasted the positive dynamics with two major drawbacks: finances and missed U.S. experiences. Nevertheless, our participants unanimously affirmed their respective decisions to study at Oxford and highly recommended the experience to future potential applicants

Non-invasive methods of identifying and tracking wild squid

The ability to identify individual free-living animals in the field is an important method for studying their behavior. Apart from invasive external or internal tags, which may cause injury or abnormal behavior, most cephalopods cannot be tagged, as their skin is too soft and delicate for tag retention. Additionally, cephalopods remove many types of tags. However, body markings have been successfully used as a non invasive method to identify individuals of many different species of animals, including whale sharks, grey whales, seals, and zebras. We developed methods to sex and individually identify Caribbean reef squid, Sepiotheuthis sepioidea. Males showed distinct bright dots on their fins on a Basic Brown background and have a light line at the fin edge while the females had a gradual transition from Brown to Pale towards the edge of their fins without showing distinct fin-dots or lines. In the field we used four characters to distinguish individual S. sepioidea from each other – sex, relative size to each other, scars, and patterns of light-colored dots on their mantles and fins. These dot patterns are individually unique and constant in location through time. Observations in the field were backed up by an image database using illustrations and photography

Indirect selective laser sintering of apatite–wollostonite glass–ceramic

This paper develops an indirect selective laser sintering (SLS) processing route for apatite–wollastonite (A–W) glass–ceramic, and shows that the processing route, which can create porous three-dimensional products suitable for bone implants or scaffolds, does not affect the excellent mechanical and biological properties of the glass–ceramic. ‘Green parts’ with fine integrity and well-defined shape have been produced from glass particles of singlesize range or mixed-size ranges with acrylic binder in various ratios by weight. A subsequent heat treatment process has been developed to optimize the crystallization process, and an infiltration process has been explored to enhance mechanical strength. Three-point bending test results show flexural strengths of up to 102MPa, dependent on porosity, and simulated body fluid (SBF) tests show that the laser sintered porous A–W has comparable biological properties to that of conventionally produced A–W

Balancing act: exploring the tone of The Life Aquatic with Steve Zissou

This paper provides an analysis of The Life Aquatic in the context of debates around tone, irony, the Smart Film, the New Sincerity and the Quirky. It argues that Anderson is one of a small but significant number of filmmakers to escape from the indiscriminate irony of fin de sie`cle cinema, and finds The Life Aquatic Aquatic a particularly interesting film in which to explore such matters because of its ready artifice, strong elements of pastiche and measuredly preposterous excesses. Offering a critical analysis, the paper balances an engagement with some of the systemic elements of the film’s tone with the detailed organisation of tonal elements in particular sequences

Use of proton pump inhibitors to treat persistent throat symptoms: Multicentre, double blind, randomised, placebo controlled trial

Objective. To assess the use of proton pump inhibitors (PPIs) to treat persistent throat symptoms. Design. Pragmatic, double blind, placebo controlled, randomised trial. Setting. Eight ear, nose, and throat outpatient clinics, United Kingdom. Participants. 346 patients aged 18 years or older with persistent throat symptoms who were randomised according to recruiting centre and baseline severity of symptoms (mild or severe): 172 to lansoprazole and 174 to placebo. Intervention. Random blinded allocation (1:1) to either 30 mg lansoprazole twice daily or matched placebo twice daily for 16 weeks. Main outcome measures. Primary outcome was symptomatic response at 16 weeks measured using the total reflux symptom index (RSI) score. Secondary outcomes included symptom response at 12 months, quality of life, and throat appearances. Results. Of 1427 patients initially screened for eligibility, 346 were recruited. The mean age of the study sample was 52.2 (SD 13.7) years, 196 (57%) were women, and 162 (47%) had severe symptoms at presentation; these characteristics were balanced across treatment arms. The primary analysis was performed on 220 patients who completed the primary outcome measure within a window of 14-20 weeks. Mean RSI scores were similar between treatment arms at baseline: lansoprazole 22.0 (95% confidence interval 20.4 to 23.6) and placebo 21.7 (20.5 to 23.0). Improvements (reduction in RSI score) were observed in both groups—score at 16 weeks: lansoprazole 17.4 (15.5 to19.4) and placebo 15.6 (13.8 to 17.3). No statistically significant difference was found between the treatment arms: estimated difference 1.9 points (95% confidence interval −0.3 to 4.2 points; P=0.096) adjusted for site and baseline symptom severity. Lansoprazole showed no benefits over placebo for any secondary outcome measure, including RSI scores at 12 months: lansoprazole 16.0 (13.6 to 18.4) and placebo 13.6 (11.7 to 15.5): estimated difference 2.4 points (−0.6 to 5.4 points). Conclusions. No evidence was found of benefit from PPI treatment in patients with persistent throat symptoms. RSI scores were similar between the lansoprazole and placebo groups after 16 weeks of treatment and at the 12 month follow-up

A questionnaire to identify patellofemoral pain in the community: an exploration of measurement properties

Background Community-based studies of patellofemoral pain (PFP) need a questionnaire tool that discriminates between those with and those without the condition. To overcome these issues, we have designed a self-report questionnaire which aims to identify people with PFP in the community. Methods Study designs: comparative study and cross-sectional study. Study population: comparative study: PFP patients, soft-tissue injury patients and adults without knee problems. Cross-sectional study: adults attending a science festival. Intervention: comparative study participants completed the questionnaire at baseline and two weeks later. Cross-sectional study participants completed the questionnaire once. The optimal scoring system and threshold was explored using receiver operating characteristic curves, test-retest reliability using Cohen’s kappa and measurement error using Bland-Altman plots and standard error of measurement. Known-group validity was explored by comparing PFP prevalence between genders and age groups. Results Eighty-four participants were recruited to the comparative study. The receiver operating characteristic curves suggested limiting the questionnaire to the clinical features and knee pain map sections (AUC 0.97 95 % CI 0.94 to 1.00). This combination had high sensitivity and specificity (over 90 %). Measurement error was less than the mean difference between the groups. Test–retest reliability estimates suggest good agreement (N = 51, k = 0.74, 95 % CI 0.52–0.91). The cross-sectional study (N = 110) showed expected differences between genders and age groups but these were not statistically significant. Conclusion A shortened version of the questionnaire, based on clinical features and a knee pain map, has good measurement properties. Further work is needed to validate the questionnaire in community samples

Trade and the equitability of global food nutrient distribution

Access to sufficient, nutritious food is a basic human right and is necessary to achieving the United Nations’ Sustainable Development Goals. We demonstrate that international food trade, in the current global system, is essential to nutrient access and enables some poorer countries to be able to nourish up to hundreds of millions of people. Protectionist trade policies could therefore have serious negative consequences for food security
