Learner Involvement at Arabian Gulf University Self-Access Centre
Diane Malcolm
Studies in Self-Access Learning Journal , 2011,
Abstract: Arabian Gulf University (AGU) College of Medicine and Medical Sciences was established around 25 years ago to train students in the Arab Gulf states, including Bahrain, where it is located, Saudi Arabia, Kuwait, Qatar, the United Arab Emirates, and Oman to become doctors of medicine (MDs) using the problem-based learning approach (PBL). As is the case in most regional higher education institutions, entering students are expected to be proficient in English, the language through which course content is delivered. In reality, many students do not achieve the desired standard in English, thus must take one or more semesters of English language training before beginning their academic studies. IAGU has an annual intake of around 150 students of widely varying English proficiency levels, but has only recently begun to accept some students to a foundation English programme. Before that, our small English unit had to find ways of helping the least proficient improve their English skills, while providing a basis in English for medical purposes for all students, within the same course framework. Our self-access centre (SAC), though small and definitely not state of the art, has had an important role to play in accommodating the different students’ needs and interests, supplementing their course material and providing opportunities for increased language exposure.
Non-Excisional Face and Neck Tightening Using a Novel Subdermal Radiofrequency Thermo-Coaugulative Device  [PDF]
D. H. Ahn, R. S. Mulholland, Diane Duncan, Malcolm Paul
Journal of Cosmetics, Dermatological Sciences and Applications (JCDSA) , 2011, DOI: 10.4236/jcdsa.2011.14021
Abstract: 42 patients with broad age and ethnic demographics where treated with a novel, non-excisional, minimally invasive device to coagulate a very thin layer of sub-dermal septo-fascial fat, denature the deep reticular dermis and tighten the skin and sub-dermal matrix of connective tissue. The detailed treatment protocol and results are presented. Patients were observed for up to 6 month following the procedure. No major side effects were observed. The aesthetic outcome of this non-excisional procedure includes improvement of the position and shape of the cheek, lower lid-cheek junction, jawline and neck. The overall aesthetic results deliver a noticeable and impressive tightening of the soft-tissue and may be compared with a conservative, small excisional procedure. The authors propose this versatile device and treatment as a non-excisional, moderate facial rejuvenation procedure on its own, or as an adjunct to open procedures performed simultaneously, or as a simplified treatment for secondary skin laxity in combination with a lift procedure.

Malcolm P Cutchin, Susan Coppola, Vibeke Talley, Judie Svihula, Diane Catellier, Kendra Shank
BMC Geriatrics , 2009, DOI: 10.1186/1471-2318-9-54
Abstract: The study is a single-blind randomized controlled pilot trial designed to assess the feasibility, and to obtain preliminary efficacy estimates, of an intervention consisting of preventive home visits to community-dwelling older adults. An occupational therapy-based preventive home visit (PHV) intervention was developed and is being implemented and evaluated using a repeated measures design. We recruited a sample of 110 from a population of older adults (75+) who were screened and found to be at-risk for functional decline. Participants are currently living in the community (not in assisted living or a skilled nursing facility) in one of three central North Carolina counties. After consent, participants were randomly assigned into experimental and comparison groups. The experimental group receives the intervention 4 times over a 12 month follow-up period while the comparison group receives a minimal intervention of mailed printed materials. Pre- and post-intervention measures are being gathered by questionnaires administered face-to-face by a treatment-blinded research associate. Key outcome measures include functional ability, participation, life satisfaction, self-rated health, and depression. Additional information is collected from participants in the experimental group during the intervention to assess the feasibility of the intervention and potential modifiers. Fidelity is being addressed and measured across several domains.Feasibility indications to date are positive. Although the protocol has some limitations, we expect to learn enough about the intervention, delivery and effects to support a larger trial with a more stringent design and enhanced statistical power.ClinicalTrials.gov ID NCT00985283The current state of affairs in population aging and gerontology in the USA and abroad set the stage for this study protocol. While an extraordinarily large cohort of the population is moving into the latter phases of life, the resources to fund both acute and long t
Analytical Evaluation of Omega 3 Fatty Acids Imbedded in Hydrophobic Starch in the Rumen  [PDF]
Malcolm Ballard
Open Journal of Animal Sciences (OJAS) , 2018, DOI: 10.4236/ojas.2018.84032
Abstract: Two experiments were conducted to assess the value of hydrophobic starch as a method to encapsulate a supplement consisting of refined fish oil intended for use as a feed supplement for ruminant animals. In Study 1, the product was incubated in vitro for 24 hours. The entire media was analyzed to determine fatty acid composition. In Study 2, the test material was incubated for 0, 2, 4, 6, 8, 10, 12 and 24 hours in order to determine rate of loss of dry matter, as well as the fatty acid profile of the dry matter remaining at 24 hours. Results from Study 1 indicated that 61.1 % of the eicosapentaenoic acid (C20:5) and 75.3% docosahexaenoic acid (C22:6) were still intact after the 24 hour incubation period. In Study 2, 39.1% of the test material was solubilized in the 24 hour period. However, the losses in C20:5 and C22:6 fatty acids were less (25.32% and 27.90% respectively) indicating that the majority of the test product was protected against biohydrogenation. It was concluded that hydrophobic starch can be used to ruminally protected fish oil and to deliver C20:5 and C22:6 fatty acids past the rumen.

Changing Hostile Beliefs towards Women through Partner Abuse Intervention Programs  [PDF]
Diane Zosky
Open Journal of Social Sciences (JSS) , 2016, DOI: 10.4236/jss.2016.42014
Abstract: This research project examined hostile beliefs towards women held by men who completed a Duluth Model partner violence intervention program. Changes in beliefs are foundational to change in the cessation of violence within the Duluth model. Hostile beliefs towards women establish a context for objectification and suspicion of women, and justification for violence. Although there was not a significant reduction in hostility scores, there was a significant reduction in aggression scores. Hostility scores were significantly correlated with the aggression scores indicating encouraging results that partner abuse intervention programs may influence the reduction of hostile beliefs towards women and thus may impact perpetration of violence.
Circulating Soluble Endoglin Levels in Pregnant Women in Cameroon and Malawi—Associations with Placental Malaria and Fetal Growth Restriction

Abstract: Placental infections with Plasmodium falciparum are associated with fetal growth restriction resulting in low birth weight (LBW). The mechanisms that mediate these effects have yet to be completely described; however, they are likely to involve inflammatory processes and dysregulation of angiogenesis. Soluble endoglin (sEng), a soluble receptor of transforming growth factor (TGF)-β previously associated with preeclampsia in pregnant women and with severe malaria in children, regulates the immune system and influences angiogenesis. We hypothesized that sEng may play a role in development of LBW associated with placental malaria (PM). Plasma levels of sEng were measured in women (i) followed prospectively throughout pregnancy in Cameroon (n = 52), and (ii) in a case-control study at delivery in Malawi (n = 479). The relationships between sEng levels and gravidity, peripheral and placental parasitemia, gestational age, and adverse outcomes of PM including maternal anemia and LBW were determined. In the longitudinal cohort from Cameroon, 28 of 52 women (54%) experienced at least one malaria infection during pregnancy. In Malawi we enrolled two aparasitemic gravidity-matched controls for every case with PM. sEng levels varied over the course of gestation and were significantly higher in early and late gestation as compared to delivery (P<0.006 and P<0.0001, respectively). Circulating sEng levels were higher in primigravidae than multigravidae from both Cameroon and Malawi, irrespective of malarial infection status (p<0.046 and p<0.001, respectively). Peripheral parasitemia in Cameroonian women and PM in Malawian women were each associated with elevated sEng levels following correction for gestational age and gravidity (p = 0.006 and p = 0.033, respectively). Increased sEng was also associated with the delivery of LBW infants in primigravid Malawian women (p = 0.017); the association was with fetal growth restriction (p = 0.003) but not pre-term delivery (p = 0.286). Increased circulating maternal sEng levels are associated with P. falciparum infection in pregnancy and with fetal growth restriction in primigravidae with PM.
Key Vulnerabilities and Limitations in the Management of Hazardous Waste and Its Disposal: A Checklist Assessment Tool  [PDF]
Rob White, Diane Heckenberg
Journal of Environmental Protection (JEP) , 2011, DOI: 10.4236/jep.2011.29145
Abstract: From an environmental protection perspective, the crucial issues pertaining to the policing of hazardous waste relate to both the vulnerabilities and limitations of current practices, and the potential issues that demand attention in the here and now, to alleviate future calamity. This paper describes the process involved in developing a vulnerabilities and limitations checklist that provides a relatively simple yet multi-pronged approach to assessing present and future environmental harms and crimes within the hazardous waste sector. Although it was not the intention of the authors to develop a generic checklist, this tool may prove useful to other industry sectors.
The VL2-Spoken Language Phonological Awareness (VL2-SLPA) Measure  [PDF]
M. Diane Clark
Psychology (PSYCH) , 2012, DOI: 10.4236/psych.2012.310137
Abstract: Tests of phonological awareness have been developed for spoken languages that require spoken responses. For many deaf individuals, spoken measures of phonological awareness (PA) are not appropriate, as these deaf individuals do not use any spoken language or their oral language is rated as low on levels of aural comprehension. Given the need to have accessible measures of spoken language PA for deaf children, the VL2 Spoken Language Phonological Awareness Measure (VL2-SLPA) was developed. The VL2-SLPA can also determine if participants use a phonological code or an orthographic code to identify the two pictures that have the same first or last “sound”. The VL2-SLPA showed strong convergent validity to the Phoneme Detection Test, another measure developed for deaf individuals, which does not require a verbal response.
Evaluation of a Rumen Protected Omega 3 Supplement for Reproduction in Dairy Cows as Determined in Three Large Herd Field Trials  [PDF]
Malcolm Ballard, Anthony T. Byrd
Open Journal of Animal Sciences (OJAS) , 2018, DOI: 10.4236/ojas.2018.83026
Abstract: Omega 3 fatty acids have been shown to support reproductive performance in dairy cows, but large amounts are needed due to ruminal biohydrogenation of fatty acids. Three long-term large herd feeding trials, two with heifers and one with mature cows, were conducted to evaluate the effects of adding a rumen protected fish oil supplement on reproduction. In all trials, there were over 1000 animals eligible to be bred/treatment. Cows received a ration with 40 g of a rumen protected fish oil supplement (Salmate®?the Ballard Group, Cincinnati Ohio) during the test periods, while controls received no supplementation. The additive was provided to the test cows from the onset of lactation until 90 ± 5 days in milk. Cows entering the pen on or after the first day of the study were included in the dataset. Individual cow records were compiled by Dairy Herd Improvement Association (National DHIA, Verona WI USA) were compared to records from the same time period the year prior. Results were compared using ANOVA for single mean variables and Fisher’s exact test for proportional data. In trials 1 and 2 involving heifers, pregnancy rates were improved (22.4% vs 14.8% in trial 1 and 22.0 vs 17.8% in trial 2, (p < 0.05)). In both cases the improved pregnancy rate could be attributed to higher numbers of cattle bred that became pregnant (P < 0.05), resulting in fewer services/conception (P < 0.05). Early embryonic abortion rates were under 2% in trial 1 and did not differ by treatment. Embryonic abortions rates were 9.2% for the control group as compared to 5.6% for the test group in trial 2, but failed to reach significance. There were no differences in pregnancy rates for the mature cows evaluated in trial 3 (P > 0.05). However, early embryonic abortion rates were 16.8 during the control period, as compared to 4.7% during the test feeding period. The rumen protected omega 3 fatty acid supplement was found to be of
