Predicting Academic Success of Health Science Students for First Year Anatomy and Physiology

Students commencing tertiary education enter through a number of traditional and alternative academic pathways. As a result, tertiary institutions encounter a broad range of students, varying in demographic, previous education, characteristics and academic achievement. In recent years, the relatively constant increase in tertiary applications in Australia has not translated to an increase in student retention or graduate numbers. The Health Sciences discipline typically falls within this paradigm, prompting various approaches to promote academic success and overall student retention. In this study, the demographic and previous education of health science students at an Australian University, were analysed along with first year science grades from a core first year anatomy and physiology unit. A generalized linear model (GLM) demonstrated statistically significant relationships between performance in the unit (measured by grade point average) and year 12 Australian Tertiary Admissions Rank (ATAR) subjects (human biology and chemistry; p

Sleep disturbance and serum ferritin levels associate with high impulsivity and impulse control disorders in male Parkinson\u27s Disease patients

Impulse control disorders (ICDs) occur in a subset of Parkinson’s disease (PD) patients on dopaminergic medications however there are currently no reliable markers to identify patients at risk. Sleep disturbances are more common in patients with an ICD. Serum ferritin levels have been associated with PD disease stage and progression, but have not previously been associated with impulsivity levels. The objective of this study was to determine if serum ferritin levels and sleep disturbance are associated with high traits of impulsivity and ICD in a cohort of PD patients attending a movement disorders clinic. This study assessed impulsiveness in 87 PD patients using the Barratt Impulsiveness Scale. Severity of sleep disturbance was determined using the sleep-related items of the MDS-UPDRS. Serum ferritin, iron and transferrin levels were measured in patients, as well as 36 age-matched healthy controls. Serum ferritin levels were significantly elevated in male PD patients in the high impulsivity group compared to patients in the low (p=.022) and normal range groups (p=.024) and showed a linear increase across the three groups. Sleep disturbance also demonstrated a linear trend, which was most severe in the high impulsivity group (p=.030). A subgroup of 11 male PD patients who fulfilled the DSM-5 criteria for an ICD had significantly higher ferritin levels and more severe sleep disturbance when compared with the remaining male PD cohort. Serum ferritin levels and sleep disturbance severity are highlighted as potential markers for abnormal impulsivity and ICD in PD patients

Evidence-based policy as iterative learning:the case of EU biofuels targets

In recent years, certain attempts to promote sustainable transport have fallen victim to the impact of ‘unintended consequences’ on decision-making and policy outcomes. The pressure that European Union biofuel targets place on global food production and the role they play in facilitating deforestation are well-known examples. This paper highlights how policy-makers’ failure to consider evidence relating to the potential impacts of biofuel mandates in the early 2000s led to a host of complex problems developing over subsequent years. Drawing on the concept of problem ‘framing’, the article then examines the extent of policy learning that has taken place since the Biofuels Directive was implemented in 2003. While acknowledging that not all eventualities can be prepared for, the article highlights the importance of enhanced communication and collaboration across different levels and departments of government in policy-making processes as a means of promoting learning, especially when dealing with complex cross-cutting and international social, environmental and economic problems

Mathematics: A good predictor for success in a health science degree

Research-based literature indicates that secondary school mathematics performance is highly predictive of university performance Moreover, scholars suggest that success in secondary mathematics courses translates into success in tertiary degrees where mathematics is required. This paper examines the extent to which the completion of secondary school mathematics courses is predictive of academic success for 57 first-year students enrolled in a Health Science degree at The University of Notre Dame Australia (UNDA) (Fremantle Campus). Using the University’s databases, the level of mathematics completed at secondary school was examined against gender, Tertiary Entrance Ranking (TER) and Grade Point Average (GPA). A statistical analysis of collected data revealed that irrespective of gender, students who completed 3C3D mathematics at secondary school had a significantly (p = .00) higher GPA, than those students who had studied level 2C2D mathematics. These findings are discussed briefly in light of the current literature presented

Student perceptions to teaching undergraduate anatomy in Health Sciences

Anatomy and physiology teaching has undergone significant changes to keep up with advances in technology and to cater for a wide array of student specific learning approaches. This paper examines perceptions towards a variety of teaching instruments, techniques, and innovations used in the delivery and teaching of anatomy and physiology for health science students, and asks whether active learning through more progressive methods of teaching is beneficial for students across health science disciplines. In total, 138 health science students consisting of 32 biomedical science students, 52 exercise and sports science students, and 54 health and physical education students completed the retrospective study. Biomedical science students were least receptive to progressive teaching modalities, preferring anatomical dissections to laboratory workbooks (p ppp\u3c 0.005) when discussing all material in the course. The results obtained demonstrate differences amongst cohorts, which indicate that student perceptions to learning anatomy and physiology are dependent on individual course expectations. Moreover, these results support “hands on” practical teaching, and the use of a variety of teaching tools to foster learning and enjoyment of anatomy and physiology in health sciences

Understanding the performance of water supply systems during mild to extreme droughts

The association between secondary mathematics and first year university performance in health sciences

In recent years, there has been a significant decline in the rate of participation in secondary school mathematics courses within Australia, particularly in advanced or higher level mathematics. The aim of this study was to investigate how grade point average (GPA) differed between five health science degrees at an Australian university. The association between Australian Tertiary Admission Ranking (ATAR), the level of mathematics completed at secondary school and GPA was also investigated. Results showed that students studying Biomedical Sciences and Physiotherapy had significantly higher GPA and ATAR than students studying Exercise and Sports Science, Physical Education, and Nursing. A higher percentage of Biomedical Science, and Physiotherapy students undertook advanced mathematics (3C3D MAT) at secondary school than students in the other three degrees, who recorded lower secondary school mathematics result scores from an intermediate or elementary mathematics course studied (3A3B and 2C2D MAT, respectively). The results of this study accord with published literature from other university courses that the decline in numbers of students opting to undertake a higher level of mathematics at secondary school will impact negatively upon their first year university performance

Extended Timed Up and Go assessment as a clinical indicator of cognitive state in Parkinson\u27s disease

Objective: To evaluate a modified extended Timed Up and Go (extended-TUG) assessment against a panel of validated clinical assessments, as an indicator of Parkinson’s disease (PD) severity and cognitive impairment. Methods: Eighty-seven participants with idiopathic PD were sequentially recruited from a Movement Disorders Clinic. An extended-TUG assessment was employed which required participants to stand from a seated position, walk in a straight line for 7 metres, turn 180 degrees and then return to the start, in a seated position. The extended-TUG assessment duration was correlated to a panel of clinical assessments, including the Unified Parkinson’s Disease Rating Scale (MDS-UPDRS), Quality of Life (PDQ-39), Scales for Outcomes in Parkinson’s disease (SCOPA-Cog), revised Addenbrooke’s Cognitive Index (ACE-R) and Barratt’s Impulsivity Scale 11 (BIS-11). Results: Extended-TUG time was significantly correlated to MDS-UPDRS III score and to SCOPA-Cog, ACE-R (p\u3c0.001) and PDQ-39 scores (p\u3c0.01). Generalized linear models determined the extended-TUG to be a sole variable in predicting ACE-R or SCOPA-Cog scores. Patients in the fastest extended-TUG tertile were predicted to perform 8.3 and 13.4 points better in the SCOPA-Cog and ACE-R assessments, respectively, than the slowest group. Patients who exceeded the dementia cut-off scores with these instruments exhibited significantly longer extended-TUG times. Conclusions: Extended-TUG performance appears to be a useful indicator of cognition as well as motor function and quality of life in PD, and warrants further evaluation as a first line assessment tool to monitor disease severity and response to treatment. Poor extended-TUG performance may identify patients without overt cognitive impairment form whom cognitive assessment is needed

Stress and Sleep Quality: Mediating Effects of Social Support

Stress is defined as the “nonspecific response of the body to any demand made upon it” (Kohn & Frazer, 1986). Stress is among the top five threats to academic performance among college students (Pettit & DeBarr, 2011). The purpose of the study was to investigate whether stress affects perceived sleep quality, as mediated by social support, and to determine whether stress levels vary based on academic major. Using ANOVA in SPSS 24, we tested three hypotheses: stress and sleep quality are negatively correlated, social support mediates the relationship between stress and sleep quality, and stress levels will vary by academic major (specifically that science, technology, engineering, and mathematics majors will show greater perceived amounts of stress). Results of this study show that there is positive correlation between sleep and stress, a negative correlation between social support and sleep, and a negative correlation between stress and social support

Race, Class, and the Distribution of Radioactive Waste in New England

Objective. Inequity in the distribution of environmental burdens among social groups, for example, minority and disadvantaged segments of the population, is an important topic in policy research. This research has largely focused on hazardous waste facilities and Superfund sites. Yet federal mandates to the states raise similar concerns over the social distribution of low-level radioactive waste facilities (LLRWFs). This study seeks to provide the first evaluation of equity in the distribution of LLRWFs within a state. Methods. We use data from the 1990 Census to compare selected characteristics of tracts with low-level radioactive waste facilities to tracts without, tracts nearby LLRWFs to those more distant, and tracts with LLRWFs, which may be more, and less, undesirable to other tracts. Results. Findings suggest that communities with LLRWFs differ from other tracts in their residents\u27 racial composition, socioeconomic status, industrial employment, and housing characteristics. LLRWFs more likely to be viewed as undesirable are even more likely to be located in areas with fewer white and affluent populations. Conclusions. Despite difficulties in assessing the relative risks and benefits of LLRWFs, our results support concern for environmental justice issues in the future siting of LLRWFs and in mandated state planning for low-level radioactive waste long-term storage
