International Symposium White Paper: Principal Work–life Balance and Well-being Matters

In November 2016, delegates from over 32 school leader associations (SLAs) from across the globe participated in the third Annual International Symposium on the Role of Professional Associations for School Leaders held in Toronto, Ontario. The symposium explored research on work intensification, generational theory and its influence on principal work and aspirations, and work-life balance and well- being. This White Paper draws on the work of the symposium and the wider evidence base to argue that we currently face a crisis in principal well-being on a global scale that, without urgent policy and practice intervention, will impact school- and system-level outcomes for generations. We argue for the importance of national and local recognition and understanding of the current status of principal well-being and work-life balance, highlight the factors and conditions that impact the work of principals with implications for well- being and work-life balance in the role, and proffer strategies and interventions that SLAs can undertake to enhance and promote principal well-being....a crisis in principal well-being on a global scale. School leaders have an influential and essential role in securing student academic and personal success, creating the conditions required for school improvement by acting as ‘lead learners’, focusing intently on the quality of teaching and learning. Yet there is growing evidence of a global transformation in the roles and nature of principal work (UNESCO 2009; OECD 2003, 2008) shaped by global patterns of educational reform over the last decade (Fullan 2008; Evans 2016; Edge 2016), the rapidity of innovation in information and communication technology (ICT) and its integration into the work and personal lives of educators and students (Dibbon & Pollock 2007; Gurr 2004, 2000: Pollock & Hauseman 2017; Pollock 2015; Carroll 2010), and the growing diversity (and growing awareness of diversity) of student populations and student needs (Ryan 2006; Briscoe & Pollock 2017; ATA 2014; Pollock, Wang & Hauseman 2015). The resulting escalation in workload brought about by these shifts has been described as “principal work intensification” – a phenomenon defined by an increasing volume and complexity of school leaders’ work, roles and responsibilities (Pollock 2014, 2015, 2016; Pollock, Wang & Hauseman 2015). Principals in several jurisdictions are reporting term-time work hours between 50 and 65 hours a week (Riley 2013, 2014, 2015; Bristow, Ireson & Coleman 2007; Alberta Teachers’ Association 2014). In a 2012 MetLife Foundation principal survey “75 percent of the respondents said that the job had become too complex,” creating undue stress (Pollock et al 2012, p. 3). Work intensification hinders the development and sustainable healthy work-life balance, with significant implications for principal well-being (La Placa et al 2013) and subsequently the well-being of schools and school systems. ...intended and unintended consequences. Globalization, demographic changes, growing global awareness of social equity and human rights issues, and rapid technological innovation create a demand and pressure on public education systems to respond and adapt. Over the last decade, educational change in many jurisdictions has been characterized by a rapid flow of initiatives designed to improve student outcomes. These shifts are occurring against a backdrop of structural and funding pressures that demand increased flexibility and creativity from school leaders, without a concomitant increase in, and at times a reduction of committed resources (Auerbach 2012; Barr & Saltamrsh 2014; Ontario Ministry of Education 2010; People for Education 2012; Sanders 2014; Wallace Foundation 2013). The constant pressure to adopt new programs, a lack of alignment between reforms, and competing accountability systems for different initiatives all contribute to work intensification and negative well-being outcomes for school leaders. Under these conditions, the increasing challenges to principal work-life balance and well-being are creating multifaceted implications for schools and school systems. The principalship is an increasingly undesirable position for prospective and current administrators, creating issues of both recruitment and retention across systems (Leithwood & Azah 2014a, b). Simultaneously, current school leaders find themselves pulled away from instructional leadership, with time increasingly co-opted by operational, accountability and administrative demands created by misaligned system-level priorities (SPEF 2015; The Human Cost 2014; Riley 2014). ...support and advocacy, practice and decision-making. SLAs play an important role in addressing these pressures, acting as knowledge brokers, advocates and policy activists for the well-being of their constituents. Globally, SLAs are developing strategies to support their members’ well-being and advocate for better approaches to work-life balance. Building on the current best practices and experience of symposium participants, this White Paper makes several recommendations for areas of advocacy and operational support that address the unintended consequences arising from the pace and scale of education reform, the growing centrality of ICT, and the changing nature of the principals’ role. These recommendations fall into four key categories: • Jurisdictional policy advocacy • Redefining the principals role • Advocacy for school- and system-level support and • Delivery of support and development opportunities. The applicability of specific recommendations depends on local and national context, SLA jurisdiction, mandate and membership structure. Importantly, while SLAs can act as advocates for policy change, work to share resources, and offer continued professional learning, coaching and mentoring for their members, the challenge of addressing principal well-being and work-life balance extends beyond principals and their professional associations: it rests in the hands of policy makers and school systems

Creating the good life? A wellbeing perspective on cultural value in rural development

This is the final version. Available on open access from Elsevier via the DOI in this recordIn the last two decades academic and policy interest in the economic growth potential of the cultural sector has risen sharply in UK, as well as in other OECD countries. Alongside this there has been a shift in cultural policies away from a focus on the public value of culture to the economic value of creativity. Where public funds are allocated to arts and culture this is heavily and increasingly skewed towards London. Although there is wide recognition of the intrinsic value of the arts and the inequalities of provision, culture is increasingly invoked as a narrowly instrumental concept for other policy aims. The new discourses of creative economies have been slow to reach rural studies and where discussions of the 'creative countryside' have taken place, notions of rural cultural value remain largely within an instrumentalist discourse. This paper is an attempt to shift the discussion to new ground by exploring cultural value through the lens of a social justice approach to wellbeing, based on the capabilities approach, using material from an AHRC funded year-long knowledge exchange project with rural arts organisations in Northumberland. The paper argues against the narrow instrumentalism of culture as a delivery mechanism for other policy agendas and offers a different conceptual framework based on social justice for considering the value of culture in conceptions of a 'good life'. It finds that using such an approach allows a different conceptual space and a clearer normative basis for understanding and arguing for the intrinsic value of culture in rural development.Arts and Humanities Research Council (AHRC

Evaluating the use of robotic and virtual reality rehabilitation technologies to improve function in stroke survivors: A narrative review

This review evaluates the effectiveness of robotic and virtual reality technologies used for neurological rehabilitation in stroke survivors. It examines each rehabilitation technology in turn before considering combinations of these technologies and the complexities of rehabilitation outcome assessment. There is high-quality evidence that upper-limb robotic rehabilitation technologies improve movement, strength and activities of daily living, whilst the evidence for robotic lower-limb rehabilitation is currently not as convincing. Virtual reality technologies also improve activities of daily living. Whilst the benefit of these technologies over dose-controlled conventional rehabilitation is likely to be small, there is a role for both technologies as part of a broader rehabilitation programme, where they may help to increase the intensity and amount of therapy delivered. Combining robotic and virtual reality technologies in a rehabilitation programme may further improve rehabilitation outcomes and we would advocate randomised controlled trials of these technologies in combination

Vaccines for COVID-19

Since the emergence of COVID-19, caused by the SARS-CoV-2 virus, at the end of 2019 there has been an explosion of vaccine development. By the 1st September 2020, a staggering number of vaccines (over 200) had started pre-clinical development of which 39 had entered clinical trials, including some approaches that have not previously been licensed for human vaccines. Vaccines have been widely considered as part of the exit strategy to enable the return to previous patterns of working, schooling and socialising. Importantly, to effectively control the COVID-19 pandemic, production needs to be scaled up from a small number of pre-clinical doses to enough filled vials to immunise the world's population, which requires close engagement with manufacturers and regulators. It will require a global effort to control the virus, necessitating equitable access for all countries to effective vaccines. This review explores the immune responses required to protect against SARS-CoV-2 and the potential for vaccine-induced immunopathology. It describes the profile of the different platforms and the advantages and disadvantages of each approach. The review also addresses the critical steps between promising pre-clinical leads and manufacturing at scale. The issues faced during this pandemic and the platforms being developed to address it will be invaluable for future outbreak control. Nine months after the outbreak began, we are at a point where pre-clinical and early clinical data is being generated for the vaccines, an overview of this important area will help our understanding of the next phases

Insulin Resistance and the IGF-I-Cortical Bone Relationship in Children Ages 9-13 Years

IGF-I is a pivotal hormone in pediatric musculoskeletal development. Although recent data suggest that the role of IGF-I in total body lean mass and total body bone mass accrual may be compromised in children with insulin resistance, cortical bone geometric outcomes have not been studied in this context. Therefore, we explored the influence of insulin resistance on the relationship between IGF-I and cortical bone in children. A secondary aim was to examine the influence of insulin resistance on the lean mass-dependent relationship between IGF-I and cortical bone. Children were otherwise healthy, early adolescent black and white boys and girls (ages 9 to 13 years) and were classified as having high (n = 147) or normal (n = 168) insulin resistance based on the homeostasis model assessment of insulin resistance (HOMA-IR). Cortical bone at the tibia diaphysis (66% site) and total body fat-free soft tissue mass (FFST) were measured by peripheral quantitative computed tomography (pQCT) and dual-energy X-ray absorptiometry (DXA), respectively. IGF-I, insulin, and glucose were measured in fasting sera and HOMA-IR was calculated. Children with high HOMA-IR had greater unadjusted IGF-I (p < 0.001). HOMA-IR was a negative predictor of cortical bone mineral content, cortical bone area (Ct.Ar), and polar strength strain index (pSSI; all p ≤ 0.01) after adjusting for race, sex, age, maturation, fat mass, and FFST. IGF-I was a positive predictor of most musculoskeletal endpoints (all p < 0.05) after adjusting for race, sex, age, and maturation. However, these relationships were moderated by HOMA-IR (pInteraction < 0.05). FFST positively correlated with most cortical bone outcomes (all p < 0.05). Path analyses demonstrated a positive relationship between IGF-I and Ct.Ar via FFST in the total cohort (βIndirect Effect = 0.321, p < 0.001). However, this relationship was moderated in the children with high (βIndirect Effect = 0.200, p < 0.001) versus normal (βIndirect Effect = 0.408, p < 0.001) HOMA-IR. These data implicate insulin resistance as a potential suppressor of IGF-I-dependent cortical bone development, though prospective studies are needed

Oxide Dispersion Strengthened Nickel Based Alloys via Spark Plasma Sintering

Oxide dispersion strengthened (ODS) nickel based alloys were developed via mechanical milling and spark plasma sintering (SPS) of Ni–20Cr powder with additional dispersion of 1.2 wt% Y2O3 powder. Furthermore, 5 wt% Al2O3 was added to Ni–20Cr–1.2Y2O3 to provide composite strengthening in the ODS alloy. The effects of milling times, sintering temperature, and sintering dwell time were investigated on both mechanical properties and microstructural evolution. A high number of annealing twins was observed in the sintered microstructure for all the milling times. However, longer milling time contributed to improved hardness and narrower twin width in the consolidated alloys. Higher sintering temperature led to higher fraction of recrystallized grains, improved density and hardness. Adding 1.2 wt% Y2O3 to Ni–20Cr matrix significantly reduced the grain size due to dispersion strengthening effect of Y2O3 particles in controlling the grain boundary mobility and recrystallization phenomena. The strengthening mechanisms at room temperature were quantified based on both experimental and analytical calculations with a good agreement. A high compression yield stress obtained at 800 °C for Ni–20Cr–1.2Y2O3–5Al2O3 alloy was attributed to a combined effect of dispersion and composite strengthening

Single-ion magnetism in the extended solid-state: insights from X-ray absorption and emission spectroscopy.

From Europe PMC via Jisc Publications RouterHistory: ppub 2020-10-01, epub 2020-10-07Publication status: PublishedLarge single-ion magnetic anisotropy is observed in lithium nitride doped with iron. The iron sites are two-coordinate, putting iron doped lithium nitride amongst a growing number of two coordinate transition metal single-ion magnets (SIMs). Uniquely, the relaxation times to magnetisation reversal are over two orders of magnitude longer in iron doped lithium nitride than other 3d-metal SIMs, and comparable with high-performance lanthanide-based SIMs. To understand the origin of these enhanced magnetic properties a detailed characterisation of electronic structure is presented. Access to dopant electronic structure calls for atomic specific techniques, hence a combination of detailed single-crystal X-ray absorption and emission spectroscopies are applied. Together K-edge, L2,3-edge and Kβ X-ray spectroscopies probe local geometry and electronic structure, identifying iron doped lithium nitride to be a prototype, solid-state SIM, clean of stoichiometric vacancies where Fe lattice sites are geometrically equivalent. Extended X-ray absorption fine structure and angular dependent single-crystal X-ray absorption near edge spectroscopy measurements determine FeI dopant ions to be linearly coordinated, occupying a D 6h symmetry pocket. The dopant engages in strong 3dπ-bonding, resulting in an exceptionally short Fe-N bond length (1.873(7) Å) and rigorous linearity. It is proposed that this structure protects dopant sites from Renner-Teller vibronic coupling and pseudo Jahn-Teller distortions, enhancing magnetic properties with respect to molecular-based linear complexes. The Fe ligand field is quantified by L2,3-edge XAS from which the energy reduction of 3d z 2 due to strong 4s mixing is deduced. Quantification of magnetic anisotropy barriers in low concentration dopant sites is inhibited by many established methods, including far-infrared and neutron scattering. We deduce variable temperature L3-edge XAS can be applied to quantify the J = 7/2 magnetic anisotropy barrier, 34.80 meV (∼280 cm-1), that corresponds with Orbach relaxation via the first excited, M J = ±5/2 doublet. The results demonstrate that dopant sites within solid-state host lattices could offer a viable alternative to rare-earth bulk magnets and high-performance SIMs, where the host matrix can be tailored to impose high symmetry and control lattice induced relaxation effects

The development of endomycorrhizal root systems VIII. Effects of soil phosphorus and fungal colonization on the concentration of soluble carbohydrates in roots

Concentrations of phosphorus in shoot and soluble carbohydrates (fructose, glucose, sucrose and fructans) in root were measured in non-mycorrhizal and vesicular-arbuscular (VA) mycorrhizal (Glomus mosseae) leek plants (Allium porrum) raised at six concentrations of soil phosphate. In conditions when an increased concentration of soil phosphate reduced VA mycorrhizal infection, the concentrations of soluble carbohydrates in the root were at a maximum. Therefore the hypothesis that greater concentrations of soluble carbohydrates in roots favour VA mycorrhizal infection is discounted. There was a specific effect of VA mycorrhizas, in that infected roots contained a larger concentration of sucrose than did uninfected roots, in plants with similar phosphorus concentrations in dry matter of shoots. We conclude, first, that increased phosphorus supply from either phosphate addition to soil or VA mycorrhizal infection increases concentration of soluble carbohydrates in leek roots and, secondly, that the VA mycorrhizal root behaves as a particularly strong physiological sink when there is an excess concentration of sucrose in the host

Does practicing hatha yoga satisfy recommendations for intensity of physical activity which improves and maintains health and cardiovascular fitness?

Background: Little is known about the metabolic and heart rate responses to a typical hatha yoga session. The purposes of this study were 1) to determine whether a typical yoga practice using various postures meets the current recommendations for levels of physical activity required to improve and maintain health and cardiovascular fitness; 2) to determine the reliability of metabolic costs of yoga across sessions; 3) to compare the metabolic costs of yoga practice to those of treadmill walking. Methods: In this observational study, 20 intermediate-to-advanced level yoga practitioners, age 31.4 ± 8.3 years, performed an exercise routine inside a human respiratory chamber (indirect calorimeter) while wearing heart rate monitors. The exercise routine consisted of 30 minutes of sitting, 56 minutes of beginner-level hatha yoga administered by video, and 10 minutes of treadmill walking at 3.2 and 4.8 kph each. Measures were mean oxygen consumption (VO2), heart rate (HR), percentage predicted maximal heart rate (%MHR), metabolic equivalents (METs), and energy expenditure (kcal). Seven subjects repeated the protocol so that measurement reliability could be established. Results: Mean values across the entire yoga session for VO2, HR, %MHR, METs, and energy/min were 0.6 L/kg/min; 93.2 beats/min; 49.4%; 2.5; and 3.2 kcal/min; respectively. Results of the ICCs (2,1) for mean values across the entire yoga session for kcal, METs, and %MHR were 0.979 and 0.973, and 0.865, respectively. Conclusion: Metabolic costs of yoga averaged across the entire session represent low levels of physical activity, are similar to walking on a treadmill at 3.2 kph, and do not meet recommendations for levels of physical activity for improving or maintaining health or cardiovascular fitness. Yoga practice incorporating sun salutation postures exceeding the minimum bout of 10 minutes may contribute some portion of sufficiently intense physical activity to improve cardio-respiratory fitness in unfit or sedentary individuals. The measurement of energy expenditure across yoga sessions is highly reliable

BioPhysConnectoR: Connecting Sequence Information and Biophysical Models

<p>Abstract</p> <p>Background</p> <p>One of the most challenging aspects of biomolecular systems is the understanding of the coevolution in and among the molecule(s).</p> <p>A complete, theoretical picture of the selective advantage, and thus a functional annotation, of (co-)mutations is still lacking.
