Commencing nursing students' perceptions and anxiety of bioscience

It is known that bioscience is perceived to be difficult and causes anxiety within undergraduate nursing students; yet, commencing students' perceptions of bioscience is not known. Therefore, the aim of this study was to ascertain incoming students' perceptions, knowledge and approaches to learning bioscience. Incoming students to the Bachelor of Nursing completed a questionnaire prior to undertaking bioscience. Two hundred and seventy three students completed the questionnaire that explored their expectations, preconceptions of bioscience content, approaches to learning bioscience, and relationship to clinical practice in the context of biosciences. Participant ages ranged from 17 to 53 (mean 23 years), and 78% of students had completed at least one secondary school science subject, of which 60% had studied biology. Overall, students' preconceptions included anxiety about studying bioscience, bioscience being difficult and harder than nursing subjects, and that more content will be required for bioscience than nursing subjects. Analysis using ANOVA revealed the relationships for secondary school science and age on student responses. A significant effect of secondary school science was found for science in school being advantageous for bioscience (p = 0.010), understanding what bioscience entails (p = 0.002), needing to study science prior to the start of the semester (p = 0.009), and that bioscience is considered difficult (p = 0.029). A significant effect of age was found for exams being more difficult than other assessments (p = 0.000) and for being able to see the relevance of nursing when reaching the workplace (p = 0.011). The findings also indicated that perceptions and associated anxieties related to bioscience were present in commencing students, similar to those which have been reported previously in established student groups. This strongly suggests that the faculty should attempt to dispel preconceptions about bioscience and target improved supports to facilitate the transition of students into the commencement of bioscience for nursing students.

A framework of Dynamic Difficulty Adjustment in competitive multiplayer video games

The balance between player competence and the challenge presented by a task has been acknowledged as a major factor in providing optimal experience in video games. While Dynamic Difficulty Adjustment (DDA) presents methods for adjusting difficulty in real-time during singleplayer games, little research has explored its application in competitive multiplayer games where challenge is dictated by the competence of human opponents. By conducting a formal review of 180 existing competitive multiplayer games, it was found that a large number of modern games are utilizing DDA techniques to balance challenge between human opponents. From this data, we propose a preliminary framework for classifying Multiplayer Dynamic Difficulty Adjustment (mDDA) instances.

Worrying and anxiety are some of the biggest mental health problems facing children today

People often assume children have no worries or nothing to be stressed about. However, children, like adults, do worry about a range of things. There may be times during periods of stress or change when children worry more intensely about things than usual.

Application of cepstrum pre-whitening for the diagnosis of bearing faults under variable speed conditions

Diagnostics of rolling element bearings involves a combination of different techniques of signal enhancing and analysis. The most common procedure presents a first step of order tracking and synchronous averaging, able to remove the undesired components, synchronous with the shaft harmonics, from the signal, and a final step of envelope analysis to obtain the squared envelope spectrum. This indicator has been studied thoroughly, and statistically based criteria have been obtained, in order to identify damaged bearings. The statistical thresholds are valid only if all the deterministic components in the signal have been removed. Unfortunately, in various industrial applications, characterized by heterogeneous vibration sources, the first step of synchronous averaging is not sufficient to eliminate completely the deterministic components and an additional step of pre-whitening is needed before the envelope analysis. Different techniques have been proposed in the past with this aim: The most widely spread are linear prediction filters and spectral kurtosis. Recently, a new technique for pre-whitening has been proposed, based on cepstral analysis: the so-called cepstrum pre-whitening. Owing to its low computational requirements and its simplicity, it seems a good candidate to perform the intermediate pre-whitening step in an automatic damage recognition algorithm. In this paper, the effectiveness of the new technique will be tested on the data measured on a full-scale industrial bearing test-rig, able to reproduce the harsh conditions of operation. A benchmark comparison with the traditional pre-whitening techniques will be made, as a final step for the verification of the potentiality of the cepstrum pre-whitening.

A pre-clinical functional assessment of an acellular scaffold intended for the treatment of hard-to-heal wounds

Dermal wound healing is a biochemical and cellular process critical to life. While the majority of the population will only ever experience successful wound healing outcomes, some 1-3 % of those aged over 65 years will experience wound healing delay or perpetuation. These hard-to-heal wounds are comprised of degraded and dysfunctional extracellular matrix, yet the integrity of this structure is critical in the processes of normal wound healing. As such, extracellular matrix replacements have been devised that can replace dysfunctional extracellular matrix in hard-to-heal wounds with the aim of restoring normal wound healing processes. Here we evaluated a novel synthetic matrix protein for its ability to act as an acellular scaffold that can replace dysfunctional extracellular matrix. In this regard the synthetic protein demonstrated an ability to rapidly adsorb to the dermal surface, permit cell attachment and facilitate the cellular functions essential to wound healing. When applied to deep partial thickness wounds in a porcine animal model the matrix protein also demonstrated the ability to reduce wound duration. These data provide evidence that the synthetic matrix protein has the ability to function as an acellular scaffold for wound healing purposes.

"I can't believe I just said that": Using guided reflections with non-Indigenous pre-service teachers in Australia

This paper explores the use of guided narrative reflection as a strategy used with high-achieving non-Indigenous pre-service teachers in Australia on teaching practicum. We suggest that reflections (and subsequent dialogue) can provide opportunities for non-Indigenous preservice teachers to re-think their beliefs and actions in ways that may intervene in the teaching that often causes educational disadvantage for Aboriginal and Torres Strait Islander students.

Nonlinear pre-fire and post-fire analysis of steel frames

A numerical procedure based on the plastic hinge concept for study of the structural behaviour of steel framed structures exposed to fire is described. Most previous research on fire analysis considered the structural performance due to rising temperature. When strain reversal occurs during the cooling phase, the stress–strain curve is different. The plastic deformation is incorporated into the stress–strain curve to model the strain reversal effect in which unloading under elastic behaviour is allowed. This unloading response is traced by the incremental–iterative Newton–Raphson method. The mechanical properties of the steel member in the present fire analysis follows both Eurocode 3 Part 1.2 and BS5950 Part 8, which implicitly allow for thermal creep deformation. This paper presents an efficient fire analysis procedure for predicting thermal and cooling effects on an isolated element and a multi-storey frame. Several numerical and experimental examples related to structural behaviour in cooling phase are studied and compared with results obtained by other researchers. The proposed method is effective in the fire safety design and analysis of a building in a real fire scenario. The scope of investigation is of great significance since a large number of rescuers would normally enter a fire site as soon as the fire is extinguished and during the cooling phase, so a structural collapse can be catastrophic.

Vulnerability held not to be pre-requisite for establishing a duty of care in claims of pure economic Loss

Case note Apache Energy Ltd v Alcoa of Australia Ltd (No 2) [2013] In 2011, headlines were made when Alcoa sued Apache Energy and its partners for $158 million, a loss it claimed was a consequence of Apache Energy failing to adequately inspect and maintain the gas pipelines that supplied the gas used by Alcoa in its business. As the loss was not a consequence of any property damage or injury to Alcoa, the loss is characterised as pure economic loss...

The CLIMATE schools combined study : a cluster randomised controlled trial of a universal Internet-based prevention program for youth substance misuse, depression and anxiety

Background Anxiety, depressive and substance use disorders account for three quarters of the disability attributed to mental disorders and frequently co-occur. While programs for the prevention and reduction of symptoms associated with (i) substance use and (ii) mental health disorders exist, research is yet to determine if a combined approach is more effective. This paper describes the study protocol of a cluster randomised controlled trial to evaluate the effectiveness of the CLIMATE Schools Combined intervention, a universal approach to preventing substance use and mental health problems among adolescents. Methods/design Participants will consist of approximately 8400 students aged 13 to 14-years-old from 84 secondary schools in New South Wales, Western Australia and Queensland, Australia. The schools will be cluster randomised to one of four groups; (i) CLIMATE Schools Combined intervention; (ii) CLIMATE Schools - Substance Use; (iii) CLIMATE Schools - Mental Health, or (iv) Control (Health and Physical Education as usual). The primary outcomes of the trial will be the uptake and harmful use of alcohol and other drugs, mental health symptomatology and anxiety, depression and substance use knowledge. Secondary outcomes include substance use related harms, self-efficacy to resist peer pressure, general disability, and truancy. The link between personality and substance use will also be examined. Discussion Compared to students who receive the universal CLIMATE Schools - Substance Use, or CLIMATE Schools - Mental Health or the Control condition (who received usual Health and Physical Education), we expect students who receive the CLIMATE Schools Combined intervention to show greater delays to the initiation of substance use, reductions in substance use and mental health symptoms, and increased substance use and mental health knowledge

Denial predicts outcome in anxiety following group cognitive behavioral therapy

This study aimed to explore whether participants' pretherapy coping strategies predicted the outcome of group cognitive behavioral therapy (CBT) for anxiety and depression. It was hypothesized that adaptive coping strategies such as the use of active planning and acceptance would be associated with higher reductions, whereas maladaptive coping strategies such as denial and disengagement would be associated with lower reductions in anxious and depressed symptoms following psychotherapy. There were 144 participants who completed group CBT for anxiety and depression. Measures of coping strategies were administered prior to therapy, whereas measures of depression and anxiety were completed both prior to and following therapy. The results showed that higher levels of denial were associated with a poorer outcome, in terms of change in anxiety but not depression, following therapy. These findings suggest the usefulness of using the Denial subscale from the revised Coping Orientation to Problems Experienced (COPE) as a predictor of outcome in group CBT for anxiety.

Improving dental and medical students’ psychological health using a self-development coaching program : a pilot study

Introduction: Dental and medical students worldwide, including in Saudi Arabia, have been reported to have a high incidence of poor psychological health, such as depression, stress, anxiety, and lowlife satisfaction. Self-development coaching programs have become an increasingly popular way to improve individuals’ lives. However, few studies have evaluated the psychological effects of such programs among dental and medical students. Moreover, no studies have been conducted on self-development coaching programs in Saudi Arabia. Aims: The aim of this study was to assess the feasibility of a larger study via a pilot study and to acquire preliminary findings about the effectiveness of a self-development coaching program on psychological health among dental and medical students in Saudi Arabia. Methods: A pre-post interventional study design was used to test a self-development coaching program (How to be an Ultra-Super Student) with a sample of medical students (n=17) at Umm Al-Qura University at Saudi Arabia. The outcome measures were students’ psychological distress (depression, anxiety, and stress), life satisfaction, self-efficacy, the coach, and coaching program characteristics. Results: The study showed that there was a significant improvement in depression (p=0.04), self-efficacy (p=0.02), and satisfaction with life (p=0.04), which supported the feasibility of a large study in the future. Conclusions: The study’s findings encourage the implementation of a randomized, controlled trial study with a larger sample to further test the effectiveness of using self-development coaching programs with medical and dental students in Saudi Arabia to improve their psychological health.

The construction of parents as learners about pre-school children’s development

The concept of the lifelong learner—the idea that people should be active learners throughout the lifespan—has since the 1990s gained importance in public policy. Governments in relatively wealthy countries have made the argument that the economic future of nations is tied to the ongoing participation of citizens in learning opportunities that will assist them to participate fully in society and increase their chances of employment in changing workforce conditions. More recently, policy attention has focused on the other end of the lifespan, the first years of life. With the early years now recognised as crucial for later educational success, policy attention has also focused on the importance of parenting in the early years. In the UK and Australia, for example, the effects of state interventions to facilitate ‘good parenting’ and pre-school children’s ‘readiness’ for formal schooling have been felt in a range of settings including community health services, the home and the pre-school (Gillies, 2005; Nichols & Jurvansuu, 2008; Millei & Lee, 2007; Vincent, Ball & Braun, 2010). In Australia, government policy has explicitly proposed a model of parenting as a learning process, and has urged people to cultivate their identities as learners in order to carry out their responsibilities as parents. In part the policy objectives have been to support parents to ensure that all children get a healthy and successful start to life...
