Autobiography in science education: Greater objectivity through local knowledge

In our paper we argue that (1) autobiography ought to be considered both the telling of one's story and the using of that story with others to understand and use difference productively, and (2) autobiography (as telling and interacting) dismantles the universalistic tug of science and replaces it with a push for science as local knowledge. To accomplish this dual task, we share selective autobiographical accounts of lives (autobiography as telling), and then use these accounts to have a conversation about urban science education (autobiography as interacting). Following these autobiographical accounts we then discuss how our different stories apart and together provide a greater objective insight into what it means to come-to-know science. When talking about their lives, people lie sometimes, forget a lot, exaggerate, become confused, and get things wrong. Yet, they are revealing truths. These truths don't reveal the past “as it actually was,” aspiring to a standard of objectivity. They give us instead the truths of our experiences.

Globalisation,Qualifications and Livelihoods: Towards a research agenda

The economic, political and cultural manifestations of globalisation are distinguishable from its underlying causes. The definition of globalisation used in this paper focuses on 'the reduction of obstacles to trade'. A function of both economic policy and technological advance, trade barriers, financial regulations and cross-border communications have been liberalised. These are contributing to change in the composition, control and locus of livelihoods, the skill requirements of livelihoods, and life chances and social mobility of livelihood seekers more generally. Educational qualifications and assessments mediate livelihood creation and livelihood seeking, to different degrees in different contexts. The role of assessment in the certification and selection for jobs interacts with economic globalisation in two main ways. The first is through the impact of globalisation on the composition and volume of livelihoods and the demand of both livelihood creators and livelihood seekers for qualifications. The second is through the reduction of trade and communication barriers on the internationalisation and commercialisation of the assessment and qualification business. The paper concludes with a research agenda that explores these two strands and emphasises the interactions between global, national and local contexts and influences.     

The effect of acute aerobic exercise on central arterial stiffness,wave reflections,and hemodynamics in adults with diabetes: A randomized cross-over design

BackgroundIndividuals with diabetes have greater central arterial stiffness, wave reflections, and hemodynamics, all of which promote the accelerated cardiovascular pathology seen in this population. Acute aerobic exercise has been shown to be an effective strategy for reducing central arterial stiffness, wave reflections, and hemodynamics in healthy individuals; however, the effects of acute aerobic exercise in reducing these outcomes is not well established in people with diabetes. Recently, implementation of high-intensity interval exercise (HIIE) has shown superior improvements in cardiovascular health outcomes when compared to traditional aerobic exercise. Yet, the effect of HIIE on the aforementioned outcomes in people with diabetes is not known. The purpose of this study was to (i) describe the central arterial stiffness, wave reflections, and hemodynamic responses to a bout of HIIE and moderate-intensity continuous exercise (MICE) in adults with diabetes; and (ii) compare the effects of HIIE and MICE on the aforementioned outcomes.MethodsA total of 24 adult men and women (aged 29–59 years old) with type 1 (n = 12) and type 2 (n = 12) diabetes participated in a randomized cross-over study. All participants completed the following protocols: (i) HIIE: cycling for 4 × 4 min at 85%–95% of heart rate peak (HR_peak), interspersed with 3 min of active recovery at 60%–70%HR_peak; (ii) MICE: 33 min of continuous cycling at 60%–70%HR_peak; and (iii) control (CON): lying quietly in a supine position for 30 min.ResultsA significant group × time effect was found for changes in central systolic blood pressure (F = 3.20, p = 0.01) with a transient reduction for the HIIE group but not for the MICE or CON groups. There was a significant group × time effect for changes in augmentation index at a heart rate of 75 beats/min (F = 2.32, p = 0.04) with a decrease following for HIIE and MICE but not for CON. For all other measures of central arterial stiffness and hemodynamics, no significant changes were observed (p > 0.05).ConclusionA bout of HIIE appears to lead to a greater transient reduction in central systolic blood pressure than the reduction observed following MICE; however, both HIIE and MICE improved augmentation index at a heart rate of 75 beats/min in people with diabetes. There was no significant difference in response to HIIE and MICE in all outcomes. This provides preliminary evidence on the role of HIIE on such outcomes in people with diabetes.     

Infant Attachment Insecurity and Baseline Physiological Activity and Physiological Reactivity to Interpersonal Stress: A Meta-Analytic Review

This meta-analytic review (k = 5–10; N = 258–895) examined links between attachment insecurity and physiological activity at baseline and in response to interpersonal stress elicited by separation–reunion procedures in the early life course (1–5 years). Insecurity was trivially, nonsignificantly associated with baseline physiological activity (heart rate [HR]: g = −.06; respiratory sinus arrhythmia [RSA]: g = −.06; cortisol: g = .01) and nonsignificantly associated with physiological reactivity to separation from parents (HR: g = −.001; RSA: g = .24). However, insecurity was moderately associated with heightened RSA (g = .26) and cortisol (g = .27) reactivity upon reunion with parents. Findings provide insight into the biobehavioral organization of attachment, suggesting that early insecurity is associated with heightened physiological reactivity to interpersonal stress.     

Why are they not accessing it? User barriers to clinical information access

The Medical Library Association''s InSight Initiative provides an open and collaborative environment for library and industry partners to discuss vexing problems and find solutions to better serve their users. The initiative''s fifth summit, continuing work from the previous summit, focused on understanding how users discover and access information in the clinical environment. During the summit, participants were divided into working groups and encouraged to create a tangible product as a result of their discussions. At the end of the summit, participants established a framework for understanding users'' pain points, discussed possible solutions to those points, and received feedback on their work from an End User Advisory Board comprising physicians, clinical researchers, and clinical faculty in biomedicine. In addition to the pain point framework, participants are developing MLA InSight Initiative Learning content with modules to educate librarians and publishers about critical aspects of user behavior. The 2020 Insight Initiative Fall Forum will serve as a virtual home for constructive dialogue between health sciences librarians and publishers on improving discovery and access to information.     

Adaptive expertise – a characteristic of expertise in outdoor instructors?

ABSTRACT

Background: Over the past 10 years, research has started to investigate the pedagogic practices of instructors and coaches working in adventure sports settings. Outdoor instructors face particular challenges regarding the impact the dynamic environment has on the coaching process and their students. This challenging combination of factors obliges the instructor to be agile in response. We propose that this adaptive expertise is characteristic of these factors and that adaptability may be a beneficial focus of outdoor instructor training and education.

Purpose: The major aim was to identify if adaptive expertise is an attribute of outdoor instructors? And if so, what are its characteristics in this context?

Research design and data collection: We applied a mixed methodology to a sample of outdoor instructors (n?=?64). The instructors were asked to complete a quantitative adaptive expertise inventory. We then interviewed a selected sub-sample (n?=?12).

Participants and setting: Quantitative data was collected from outdoor instructors working in the UK (n?=?64). The sample consisted of instructors qualified to work independently with groups in adventurous settings in a range of activities. Qualitative data was collected from a smaller sample (n?=?12) via a series of thematically analysed semi-structured interviews.

Findings: Results suggest that the participating outdoor instructors have high levels of adaptive expertise. A characteristic of that adaptive capacity is a combination of skills revolving around reflection, metacognition, and situational awareness. There were differences, however, between less and more experienced outdoor instructors in their adaptive capacity, with less experienced instructors being adaptive to a lesser extent.

Conclusions: The implication is that further research is worthwhile to examine the development of instructors’ adaptive capacity. The training and education of outdoor instructors requires pedagogic approaches that facilitate and engender adaptability, flexibility and agility in neophyte instructors.     

Predicting vertical ground reaction force during running using novel piezoresponsive sensors and accelerometry

ABSTRACT

Running is a common exercise with numerous health benefits. Vertical ground reaction force (vGRF) influences running injury risk and running performance. Measurement of vGRF during running is now primarily constrained to a laboratory setting. The purpose of this study was to evaluate a new approach to measuring vGRF during running. This approach can be used outside of the laboratory and involves running shoes instrumented with novel piezoresponsive sensors and a standard accelerometer. Thirty-one individuals ran at three different speeds on a force-instrumented treadmill while wearing the instrumented running shoes. vGRF was predicted using data collected from the instrumented shoes, and predicted vGRF were compared to vGRF measured via the treadmill. Per cent error of the resulting predictions varied depending upon the predicted vGRF characteristic. Per cent error was relatively low for predicted vGRF impulse (2–7%), active peak vGRF (3–7%), and ground contact time (3–6%), but relatively high for predicted vGRF load rates (22–29%). These errors should decrease with future iterations of the instrumented shoes and collection of additional data from a more diverse sample. The novel technology described herein might become a feasible way to collect large amounts of vGRF data outside of the traditional biomechanics laboratory.
