Writing across curriculum: Evaluating a faculty-centered approach

This paper discusses research on a pilot study for implementing a Writing Across the Curriculum (WAC) program in the College of Business (CoB) at a California Public University. Data analysis focused on faculty and writing assistant satisfaction using interviews, and on student learning as measured by evaluation of progressive writing assignments. Discussion includes: 1) assumptions on which the pilot was based and its goals, 2) overview of how the program was structured and implemented, 3) outcomes of the pilot program, and 4) recommendations for future programs. Results suggest both faculty and student participants were satisfied with the pilot program implementation and student writing improvement

‘The Gentle Art of Letting the Other Fellow Have Your Own Way': Viewpoints on a media narrative used to promote the proposed N2 toll road

This viewpoint paper is written in response to a South African National Roads Agency (SANRAL) advertorial published in various South African regional newspapers in February 2004. We highlight the importance of developing ‘media literacy’ – reading skills which enable the critical deconstruction of media texts. We explore, more specifically, the public relations strategies used by large corporations, and the media’s role as disseminators of corporate marketing material.We also look at the relevance in identifying the language and discourse positioning the writer, photographer, reader and their choice representative medium

Indexing dialysis dose for gender, body size and physical activity: Impact on survival

Current practice basing dialysis dose on urea distribution volume (V) has been questioned. We explored the impact on survival of scaling dialysis dose (Kt) to parameters reflective of metabolic activity. In a multicentre prospective cohort study of 1500 patients on thrice-weekly haemodialysis, body surface area (BSA) and resting energy expenditure (REE) were estimated using validated equations and physical activity by the Recent Physical Activity Questionnaire. Total energy expenditure (TEE) was estimated from REE and physical activity data. Kt was calculated from delivered (single-pool Kt/V)*Watson V. Kt/BSA, Kt/ REE and Kt/TEE were then calculated at baseline and 6 monthly during follow-up for 2 years. In adjusted Cox models Kt/TEE, Kt/BSA, Kt/REE, in that order, had lower hazard ratios for death than single-pool Kt/V. On the basis of adjusted survival differences, putative minimum target doses were estimated for Kt/BSA as 27119 ml/m 2 and Kt/TEE as 25.79 ml/ kcal. We identified spKt/V values equivalent to these estimated targets, ranging from 1.4 to 1.8 in patient groups based on gender, body size and physical activity. For sedentary patients, the minimum target dose was 1.4 for large males, 1.5 for small males and 1.7 for women. For active patients the target was 1.8 irrespective of gender and body-weight. Patients achieving these individualised minimum targets had greater adjusted two-year survival compared to those achieving conventional minimum targets. Metabolic activity related parameters, such as Kt/TEE and Kt/BSA, may have a clinically important role in scaling haemodialysis dose. Using such parameters or their spKt/V equivalents to adjust minimum target doses based on gender, body size and habitual physical activity may have a positive impact on survival.Peer reviewe

Comparison of energy estimates in chronic kidney disease using doubly-labelled water

This is the peer reviewed version of the following article: S. Sridharan, J. Wong, E. Vilar, and K. Farrington, ‘Comparison of energy estimates in chronic kidney disease using doubly-labelled water’, Journal of Human Nutrition and Dietetics, Vol. 29 (1): 59-66, February 2016, which has been published in final form at https://doi.org/10.1111/jhn.12326. This article may be used for non-commercial purposes in accordance with Wiley Terms and Conditions for Self-Archiving. © 2015 The British Dietetic Association Ltd.BACKGROUND: Total energy expenditure (TEE) is estimated in clinical practice as a combined measure of resting energy expenditure and physical activity level. Commonly available questionnaires to estimate physical activity level have not been validated in patients with kidney disease using the doubly-labelled water method. METHODS: This prospective, cross-sectional study was conducted on 40 patients with chronic kidney disease stages 1-5 with the objective of validating two physical activity questionnaires: the Recent Physical Activity Questionnaire (RPAQ) and the Stanford 7-day recall questionnaire. TEE was measured using doubly-labelled water technique. TEE was also estimated using predicted resting energy expenditure and estimated physical activity measures from the questionnaires. RESULTS: Measured TEE correlated better with TEE estimated from RPAQ compared to that from the Stanford questionnaire. In Bland-Altman analysis, TEE estimated from RPAQ had the least bias and narrower limits of agreement compared to the measured TEE. A metabolic equivalent of task value of 1.3 for the unaccounted time in RPAQ provided the best approximation of estimated TEE to the measured TEE. CONCLUSIONS: RPAQ is an acceptable questionnaire tool for assessing physical activity level in patients with chronic kidney disease.Peer reviewedFinal Accepted Versio

Common Swine Mycoplasmas

Mycoplasmas are the smallest organisms (200-300nm) that are capable of growth in cell free medium. They are different from bacteria in that they have no cell walls but are bounded by a unite membrane. The typical mycoplasma colony on solid growth medium has the appearance of a fried egg. Most mycoplasmas require sterol for growth. Nonsterol requiring mycoplasmas are placed into the genus Acholeplasma

The impact of longitudinal offending trajectories on mental health: Lifetime consequences and intergenerational transfer

Objectives: This paper set out to contribute to the literature by linking research into offending pathways with the study of longitudinal effects and intergenerational transmission of mental health. Methods: Data was used from two generations of the Cambridge Study in Delinquent Development, a longitudinal study of 411 men from London and their children who were followed since 1961-62. Results: Findings from this study (1) indicate that symptoms of depression and anxiety were highest among those who commenced offending in adulthood and (2) demonstrated familial continuity of mental health: poor offspring mental health was related to father’s criminality, but not to their offender group. Conclusions: A thorough understanding of the heterogeneity of offenders is essential for policy and practice. It is suggested that future research further examines individuals who only commence offending in adulthood, since they have been shown to not only face a variety of adverse outcomes themselves, but are also likely to have children with distinct patterns of internalizing problems across. Keywords: life-course-persistent offending, late-onset offending, adolescence-limited offending, adverse mental health outcomes, intergenerational transmissio

Comparison of resting and total energy expenditure in peritoneal dialysis patients and body composition measured by dual-energy X-ray absorptiometry

Under basal resting conditions muscle metabolism is reduced, whereas metabolism increases with physical activity. We wished to determine whether there was an association between resting energy expenditure (REE) and total energy expenditure (TEE) in peritoneal dialysis (PD) patients and lean body mass (LBM). We determined REE and TEE by recently validated equations, using doubly labelled isotopic water, and LBM by dual-energy X-ray absorptiometry (DXA) scanning. We studied 87 patients, 50 male (57.4%), 25 diabetic (28.7%), mean age 60.3±17.6 years, with a median PD treatment of 11.4 (4.7-29.5) months. The mean weight was 70.1±17.7 kg with a REE of 1509±245 kcal/day and TEE 1947±378 kcal/day. REE was associated with body size (weight r=0.78 and body mass index (BMI) r=0.72) and body composition (LBM r=0.77, lean body mass index (LBMI) r=0.76, r=0.62), all P<0.001). For TEE, there was an association with weight r=0.58, BMI r=0.49 and body composition (LBM r=0.64, LBMI (r=0.54), all P<0.001). We compared LBMI measured by DXA and that estimated by the Boer equation using anthropomorphic measurements, which overestimated and underestimated LBM for smaller patients and heavier patients, respectively. Muscle metabolism is reduced at rest and increases with physical activity. Whereas previous reports based on REE did not show any association with LBM, we found an association between both REE and TEE, using a recently validated equation derived from dialysis patients, and LBM measured by DXA scanning. Estimation of muscle mass from anthropomorphic measurements systematically overestimated LBM for small patients and conversely underestimated for heavier patients

Respiratory patient experience of measures to reduce risk of COVID-19: findings from a descriptive cross-sectional UK wide survey

Objectives: To assess the experience of people with long-term respiratory conditions regarding the impact of measures to reduce risk of COVID-19. Design: Analysis of data (n=9,515) from the Asthma UK and British Lung Foundation partnership COVID-19 survey collected online between 1st and 8th of April 2020. Setting: Community Participants: 9,515 people with self-reported long term respiratory conditions. 81% female, age ranges from <17 years to 80 and above, from all nations of the UK. Long term respiratory conditions reported included asthma (83%), Chronic Obstructive Pulmonary Disease (COPD) (10%), bronchiectasis (4%), Interstitial Lung Disease (ILD) (2%), and ‘other’ (<1%) (e.g. lung cancer and pulmonary endometriosis). Outcome measures: Study responses related to impacts on key elements of health care, as well as practical, psychological and social consequences related to the COVID-19 pandemic and social distancing measures. Results: 45% reported disruptions to care, including cancellations of appointments, investigations, pulmonary rehabilitation, treatment, and monitoring. Other practical impacts such as difficulty accessing healthcare services for other issues, and getting basic necessities such as food, were also common. 36% did not use online prescriptions and 54% had not accessed online inhaler technique videos. Psycho-social impacts including anxiety, loneliness and concerns about personal health and family were prevalent. 81% reported engaging in physical activity. Among the 11% who were smokers, 48% reported they were planning to quit smoking because of COVID-19. Conclusions: COVID-19 and related social distancing measures are having profound impacts on people with chronic respiratory conditions. Urgent adaptation and signposting of services is required to mitigate the negative health consequences of the COVID-19 response for this group

SCIMPI: A New Borehole Observatory

The Simple Cabled Instrument for Measuring Parameters in-situ (SCIMPI) is a new borehole observatory instrument designed to study dynamic processes below the seafloor. SCIMPI performs time series measurements of temperature, pressure and electrical resistivity at a series of depths, tailored for site-specific scientific objectives. SCIMPI’s modular design enables tailoring of the type, depth distribution, and frequency of measurements based on the study goals and sediment characteristics. The first prototype is designed for 300m below the seafloor in soft sediment and 1500mb.s.l. However, SCIMPI could be tailored for deeper goals. The instrument can be configured for autonomous or cabled observatory deployments and has successfully undergone a number of tests, including pressure, communications, battery life, and interfacing with other drill-ship equipment. Here we discuss the design of the instrument, its capabilities, and the testing process it has passed through during four years of development. SCIMPI was successfully deployed on the Cascadia margin within the NEPTUNE Canada observatory network during IODP Expedition 341S in May 2013
