An Assessment of the Optimal Techniques for Sampling Shallow Water Reef Fishes

I compared four methods of sampling fish assemblages, including underwater visual census, diver operated stereo-video, baited remote underwater stereo-video and a remote operated vehicle with an attached stereo-video system. Comparisons focused on the assemblage composition sampled, number of individuals and species sampled, length-based metrics and fish behaviour. I concluded that a combination of baited remote underwater stereo-video and a remote operated vehicle with attached stereo-video system is the optimal approach to sampling a representative suite of fishes

Morality or competence? The importance of affirming the appropriate dimension of self-integrity

Objectives: Two studies explored the relative efficacy of a morality-based versus a competence-based self-affirmation manipulation at increasing acceptance of personally relevant health-risk information. In accordance with prior theorising (e.g., Cohen & Sherman, 2014), it was hypothesized that the morality affirmation would be more effective than the competence affirmation in such contexts, as the former targets a different domain to that threatened by the health-risk information. Design: Both studies employed a cross-sectional experimental design. Methods: Participants were presented with a morality affirmation, competence affirmation or no affirmation control prior to reading a message about the risks of (a) not engaging in daily dental flossing (Study 1) and (b) red meat consumption (Study 2). Participants subsequently completed a number of measures assessing acceptance of the message. Results: In line with predictions, findings from both studies demonstrated that the morality affirmation precipitated greater acceptance of personally relevant health-risk information compared to the competence affirmation, as reflected in more positive attitudes (Studies 1 and 2) and intentions (Study 1). Study 2’s findings further suggested that the superior efficacy of the morality affirmation in health-related contexts could not simply be attributed to a general tendency for this affirmation to outperform the competence affirmation. Conclusions: The nature of the value affirmed may be a critical factor in determining the success of self-affirmation manipulations in health-related domains

Mid-Summer Dry Spell and Agriculture in Jamaica : Implications for farming practices, techniques and culture

At the beginning of the 21st century, Jamaica stands in a precarious situation which could have serious implications for the island's future. This stress may not have derived from a decrease in precipitation due to climate change, as well as a lack of interest in farming from smallholder farmers, which has become increasingly unsustainable. Younger Jamaicans have rejected farming as a career and instead opted for quick cash or migration out of the country in the hope of making their wealth elsewhere in the world. Thus, crop yields are at risk due to a smaller agricultural workforce. With decreasing labor rates and the current international economic crisis, the need for a high agricultural efficiency is greater than ever.   Annual yields are also affected climatologically by a mid-summer atmospheric phenomenon called the Mid-Summer Dry Spell (MSD), resulting in bimodal rainy seasons in April-June and August-November. Understanding how rainfall affects crop production is a primary goal of this research. To accomplish this, a three part analysis will be conducted utilizing correlations between rainfall and crop yield, mapping with Geographic Information Systems (GIS), and analysis of how the MSD impacts brightness, greenness and wetness of vegetation.  M.A

Thermostatic Hydraulic Valve

Final report and prototype photo for Project 18 of ME450, Fall 2010 semester.Hydraulic fluid is cooled using a radiator; for best efficiency, the hydraulic fluid temperature should be kept within a narrow range by routing only a certain percentage of the fluid to the radiator using a thermostatic valve. Unfortunately, off-the-shelf thermostatic valves are either expensive, inefficient, or have poor temperature control. This project will be to design an inexpensive thermostatic valve that will route more fluid to the radiator at high temperatures and less at low temperatures.Andrew Moskalik (USEPA)http://deepblue.lib.umich.edu/bitstream/2027.42/86245/1/ME450 Fall2010 Final Report - Project 18 - Thermostatic Hydraulic Valve.pdfhttp://deepblue.lib.umich.edu/bitstream/2027.42/86245/2/ME450 Fall2010 Prototype Photo - Project 18 - Thermostatic Hydraulic Valve.jp

Research students exhibition catalogue 2011

The catalogue demonstrates the scope and vibrancy of current inquiries and pays tribute to the creative capacity and investment of UCA research students. It brings together contributions from students who are at different stages in their research ad/venture. Their explorations are connected by the centrality of contemporary material practices as focal point for the reconsideration of societal values, cultural symbols and rituals and their meaning, and the trans/formation of individual, collective and national identities The media and formats employed range from cloth, jewellery and ceramics to analogue film, the human voice and the representation of dress and fashionin virtual environments. Thematic interests span from explorations at the interface of art and medical science to an investigation of the role of art in contested spaces, or the role of metonymy in ‘how the arts think’ And whilst the projects are motivated by personal curiosity and passion, their outcomes transcend the boundaries of individual practice and offer new insights, under-standing and applications for the benefit of wider society.

Review article – X Radiation dose implications in screening patients with ferromagnetic IOFBs prior to MRI: a literary review

Patients scheduled for a magnetic resonance imaging (MRI) scan sometimes require screening for ferromagnetic Intra Orbital Foreign Bodies (IOFBs). To assess this, they are required to fill out a screening protocol questionnaire before their scan. If it is established that a patient is at high risk, radiographic imaging is necessary. This review examines literature to evaluate which imaging modality should be used to screen for IOFBs, considering that the eye is highly sensitive to ionising radiation and any dose should be minimised. Method: Several websites and books were searched for information, these were as follows: PubMed, Science Direct, Web of Knowledge and Google Scholar. The terms searched related to IOFB, Ionising radiation, Magnetic Resonance Imaging Safety, Image Quality, Effective Dose, Orbits and X-ray. Thirty five articles were found, several were rejected due to age or irrelevance; twenty eight were eventually accepted. Results: There are several imaging techniques that can be used. Some articles investigated the use of ultrasound for investigation of ferromagnetic IOFBs of the eye and others discussed using Computed Tomography (CT) and X-ray. Some gaps in the literature were identified, mainly that there are no articles which discuss the lowest effective dose while having adequate image quality for orbital imaging. Conclusion: X-ray is the best method to identify IOFBs. The only problem is that there is no research which highlights exposure factors that maintain sufficient image quality for viewing IOFBs and keep the effective dose to the eye As Low As Reasonably Achievable (ALARA)
