Approaches to study in higher education portuguese students: a portuguese version of the Approaches and Study Skills Inventory for Students (ASSIST)

This paper examines the validity of the Approaches and Study Skills Inventory for Students—short version (ASSIST; Tait et al. in Improving student learning: Improving students as learners, 1998), to be used with Portuguese undergraduate students. The ASSIST was administrated to 566 students, in order to analyse a Portuguese version of this inventory. Exploratory factor analysis (principal axis factor analysis followed by direct oblimin rotation) reproduced the three main factors that correspond to the original dimensions of the inventory (deep, surface apathetic and strategic approaches to learning). The results are consistent with the background theory on approaches to learning. Additionally, the reliability analysis revealed acceptable internal consistency indexes for the main scales and subscales. This inventory might represent a valuable research tool for the assessment of approaches to learning among Portuguese higher education students

Differentiating between models of Epothilone binding to microtubules using tubulin mutagenesis, cytotoxicity, and molecular modeling

This is the peer reviewed version of the following article: Entwistle, R. A., Rizk, R. S., Cheng, D. M., Lushington, G. H., Himes, R. H., & Gupta, M. L. (2012). Differentiating between models of Epothilone binding to microtubules using tubulin mutagenesis, cytotoxicity, and molecular modeling. ChemMedChem, 7(9), 1580–1586. http://doi.org/10.1002/cmdc.201200286, which has been published in final form at doi.org/10.1002/cmdc.201200286. This article may be used for non-commercial purposes in accordance with Wiley Terms and Conditions for Self-Archiving.Microtubule stabilizers are powerful anti-mitotic compounds and represent a proven cancer treatment strategy. Several classes of compounds in clinical use or trials, such as the taxanes and epothilones, bind to the same region of β-tubulin. Determining how these molecules interact with tubulin and stabilize microtubules is important both for understanding the mechanism of action and enhancing chemotherapeutic potential, e.g. reducing side effects, increasing solubility, and overcoming resistance. Structural studies using nonpolymerized tubulin or stabilized polymers have produced different models of epothilone binding. Here, we used directed mutagenesis of the binding site on Saccharomyces cerevisiae β-tubulin to analyze interactions between Epothilone B and its biologically relevant substrate, dynamic microtubules. Five engineered amino acid changes contributed to a 125-fold increase in Epothilone B cytotoxicity independent of inherent microtubule stability. The mutagenesis of endogenous β-tubulin was done in otherwise isogenic strains. This facilitated the correlation of amino acid substitutions with altered cytotoxicity using molecular mechanics simulations. The results, which are based on the interaction between Epothilone B and dynamic microtubules, most strongly support the binding mode determined by NMR spectroscopy-based studies. This work establishes a system for discriminating between potential binding modes and among various compounds and/or analogues using a sensitive biological activity-based readout

A protocol for co-creating research project lay summaries with stakeholders:Guideline development for Canada's AGE-WELL Network

Background Funding bodies increasingly require researchers to write lay summaries to communicate projects’ real-world relevance to the public in an accessible way. However, research proposals and findings are generally not easily readable or understandable by non-specialist readers. Many researchers find writing lay summaries difficult because they typically write for fellow subject specialists or academics rather than the general public or a non-specialist audience. The primary objective of our project is to develop guidelines for researchers in Canada’s AGE-WELL Network of Centres of Excellence, and ultimately various other disciplines, sectors, and institutions, to co-create lay summaries of research projects with stakeholders. To begin, we produced a protocol for co-creating a lay summary based on workshops we organized and facilitated for an AGE-WELL researcher. This paper presents the lay summary co-creation protocol that AGE-WELL researchers will be invited to use. Methods Eligible participants in this project will be 24 AgeTech project researchers who are funded by the AGE-WELL network in its Core Research Program 2020. If they agree to participate in this project, we will invite them to use our protocol to co-produce a lay summary of their respective projects with stakeholders. The protocol comprises six steps: Investigate principles of writing a good lay summary, identify the target readership, identify stakeholders to collaborate with, recruit the identified stakeholders to work on a lay summary, prepare for workshop sessions, and execute the sessions. To help participants through the process, we will provide them with a guide to developing an accessible, readable research lay summary, help them make decisions, and host, and facilitate if needed, their lay summary co-creation workshops. Discussion Public-facing research outputs, including lay summaries, are increasingly important knowledge translation strategies to promote the impact of research on real-world issues. To produce lay summaries that include information that will interest a non-specialist readership and that are written in accessible language, stakeholder engagement is key. Furthermore, both researchers and stakeholders benefit by participating in the co-creation process. We hope the protocol helps researchers collaborate with stakeholders effectively to co-produce lay summaries that meet the needs of both the public and project funders

Space, Gaze and Power: A Foucauldian Methodology for Fashion Advertising Analysis

This article examines fashion imagery in regard to representations of power as they pertain to the mise en scene of fashion advertising. By employing a specific form of image critique employed by Michel Foucault in The Order of Things (1966), a new methodology for analyzing fashion advertising is proposed and formulated. This form of critique enables elements such as the gaze, light and space to be framed into lines of sight. These lines can be examined in regard to the viewing subject, the staging of the advert, and structures of power. In his critique of the painting by Diego Velázquez Las Meninas (1656 Velazquez, D. 1656. Las Meninas. Madrid: Prado Museum. [Google Scholar]), Foucault states: “No gaze is stable, or rather, in the neutral furrow of the gaze piercing at a right angle through the canvas, subject and object, the spectator and the model, reverse their roles to infinity” (2005, 5). These themes enable us to use this methodology to critique fashion imagery and this article offers up a new approach to visual analysis, one that has not been considered before and that can now be added to the fashion theory toolbox

Eye care services today and in the future rely on effective workforces, in which nurses play a pivotal role. Despite nurse involvement in eye care, there is no information describing their engagement, deployment, training, and opinion. This paper offers the first review of nurse engagement in eye care in Australia.Methods: We conducted an e-survey on Australian nurse engagement in eye care. Quantitative questions were analysed by descriptive, chi-square and bivariate correlation coefficients with assumed power of 0.80, and significance of p=0.05. Grounded theory, sentiment and saturation analysis extracted key themes, meaning and opinion from the qualitative questions.Results: There were n=238 Australian nurse participants. Results indicated they were satisfied with their role, engaged in a wide range of healthcare and eye care setting and organisations, and adapted to their employer. Task-shifting “to” and “from” nurses was not universally supported but recognised by participants as necessary. Of concern, the results suggested that 68.6% of our participants would exit eye care over the next ten years, with insufficient entry pathways into the field for graduate and early-career nurses.Conclusion: For Australia to meet and sustain eye care services for its population, steps must be taken to improve exposure and entry to the field for students, graduates, and early-career nurses. Strategies to train and prepare nurses for task-shifting are urgently required and the eye care nursing sector must professionalise to achieve positive change.Keywords: Australia, nurse, eye care, ophthalmology, blindness, workforc

Does Concomitant CABG Influence the Outcomes of Post-Myocardial Infarction Ventricular Septal Defect Repair?

Introduction: Ventricular septal defect (VSD) following myocardial infarction (MI) is a relatively infrequent complication with high mortality. Over time, understanding of the pathology and its management has resulted in improved outcomes; however, controversies remain. Objective: We sought to investigate the effect of concomitant coronary artery bypass graft (CABG) on outcomes following post-MI VSD repair. Methods: Electronic search was performed to identify all relevant studies published from 2000 to 2018. After assessment for inclusion and exclusion criteria, 66 studies were selected for the analysis. Data were extracted and pooled for systematic review and meta-analysis. Results: Average age was 68.7 years (95% CI 67.3-70.1) with 57% (95% CI 54-60) males. Coronary angiogram was available preoperatively in 94% (95% CI 92-96) of patients. Single-vessel disease was most common (47%, 95% CI 42-52) with left anterior descending coronary artery the most commonly involved vessel (55%, 95% CI 46-63). Concomitant CABG was performed in 52% (95% CI 46-57) of patients. Of these, infarcted territory was revascularized in 54% (95% CI 23-82). No significant survival difference was observed between those who had concomitant CABG versus those without CABG at 30 days (65%, 95% CI 58-72) vs (60%, 95% CI 47-72), 1 year (59%, 95% CI 50-68) vs (51%, 95% CI 41-61), and 5 years (46%, 95% CI 38-54) vs (39%, 95% CI 27-52) respectively. Discussion: Overall, concomitant CABG did not have a significant effect on survival following VSD repair, therefore, decision on revascularization should be weighed against the risks associated with prolonged cardiopulmonary bypass

Protected proteins as supplements for bulls fed tropical forage diets

Under the extensive conditions encountered in the dry tropics of Australia mating in the beef herd ususally commences immediately after the onset of the wet season. Bulls are often mated only four to six weeks after suffering a period of liveweight loss. This experiment looked at the liveweight change and reproductive responses when bulls were subject to two different planes of nutrition

A centralised public information resource for randomised trials: a scoping study to explore desirability and feasibility

BACKGROUND: There are currently several concerns about the ways in which people are recruited to participate in randomised controlled trials, the low acceptance rates among people invited to participate, and the experiences of trial participants. An information resource about on-going clinical trials designed for potential and current participants could help overcome some of these problems. METHODS: We carried out a scoping exercise to explore the desirability and feasibility of establishing such a resource. We sought the views of a range of people including people who were considering taking part in a trial, current trial participants, people who had been asked but refused to participate in a trial, consumer group representatives and researchers who design and conduct trials. RESULTS: There was broad-based support for the concept of a centralised information resource for members of the public about on-going and recently completed clinical trials. Such an information resource could be based on a database containing standardised information for each trial relating to the purpose of the trial; the interventions being compared; the implications of participation for participants; and features indicative of scientific quality and ethical probity. The usefulness of the database could be enhanced if its search facility could allow people to enter criteria such as a disease and geographic area and be presented with all the trials relevant to them, and if optional display formats could allow them to view information in varying levels of detail. Access via the Internet was considered desirable, with complementary supported access via health information services. The development of such a resource is technically feasible, but the collation of the required information would take a significant investment of resources. CONCLUSION: A centralised participant oriented information resource about clinical trials could serve several purposes. A more detailed investigation of its feasibility and exploration of its potential impacts are required
