The paper aims to explore how head teachers and other education service leaders and their teams have been experiencing shifts in their identities during the last decade of education cuts in Catalonia (Spain), and the possible effects during the current COVID-19 crisis on educational leaders. Our exploratory hypothesis covers the crisis years (2008-2015) and on into the nonrecovery years (2015-2020) until the onset of the COVID-19 pandemic. During these years, through what Ball (2008) describes as a "ratchet effect," education cuts and their everyday effects in schools produced learned helplessness (LH) in head teachers and leaders. Theoretically, we propose to examine this malaise from a political angle, seeing it as a disciplinary technology to transform education leaders' identity and practices. To corroborate this, we conducted four interviews with head teachers of different public primary, secondary, and special education schools, and a psychopedagogical service leader in the same semi-rural area in Catalonia. The exploratory results show that the incremental and selective cuts soon became a new normal and created feelings of (political) learned helplessness that may be seen not as negative side effects but as a disciplinary technology that reshaped leaders' subjectivity. At the same time, education leaders carried out some (ir)responsible practices of resistance that can be understood as care of the self and others. More research needs to be done with different agents to capture the complexity and ambiguity of cuts and LH as a political phenomenon.

Education is widely seen as a force for good, associated with hope and optimism about better individual and social futures. By contrast, and controversially, this paper argues that education and education policy in recent decades has been far from benign, as evidenced in the growing alienation of significant numbers of teachers and students and, crucially for our paper, in the growth of authoritarian models of schooling, involving 'zero-tolerance', 'no excuses' disciplinary approaches. Against this background, and drawing on Hannah Arendt and the work of contemporary moral philosophers Elizabeth Minnich and Simona Forti, this paper diagnoses the nature and effects of school discipline policies in the neoliberal era, and in particular practices such as isolation, as a contemporary form of banal, or everyday, evil.

Recent educational reforms in England have sought to reshape public education by extending central government control of curriculum and assessment, while replacing local government control of schools with a quasi-private system of academies and multi academy trusts. In this paper, we resist reading this as the latest iteration of the debate between "traditional" and "progressive" education. Instead, we note how, despite the mobilisation of the rhetoric of the public and public education, schooling in England has never been public in any deeply meaningful sense. We develop a genealogical reading of public education in England, in which ideas of British universalism -- "the public" -- and inequality and exclusion in education and society have not been opposed but have gone hand-in-hand. This raises the question whether it is possible to envisage and enact another form of collective -- one that is based on action rather than fantasy and that is co-authored by, comprising, and exists for, the people. The final part of this paper seeks to grapple with this challenge, in the context of past, present and future potential developments in education, and to consider possibilities for the imaginary reconstitution of public education in England in the twenty-first century.

Education is usually considered a force for good, associated with hope and optimism about better individual and social futures. Yet a case can be made that education and education policy in recent decades, far from being a force for good, has had nefarious effects at multiple levels. This can be seen in the growing alienation of significant numbers of teachers and students in disparate global contexts and in the growth of authoritarian models of schooling, involving 'zero-tolerance', 'no excuses' disciplinary approaches, that have undermined notions of the common school as a public good. Against this background, and drawing on philosophical literature and our own empirical research, this study interrogates the practice in schools in England of placing students in 'isolation'. In considering this practice as an instance of banal education policy, our study makes obvious reference to Hannah Arendt's characterization of evil in her account of Adolf Eichmann's trial. But it also draws on the work of moral philosophers, Elizabeth Minnich and Simona Forti, in relation to the distinction between intensive and extensive evil, in order to analyse the nature and effects of school discipline policies and practices such as isolation in the neoliberal era as a contemporary form of evil.

Primary thyroid lymphoma is one of the rare and distinct type of extra nodal lymphomas originating within the thyroid gland. It accounts for less than 5% of all thyroid malignancies and 2% of extra nodal lymphomas. It predominantly affects older adults, with a higher incidence in women. Patients typically present with a rapidly enlarging thyroid mass, accompanied by clinical symptoms of compression such as dysphagia, dyspnea, and hoarseness. Diagnosis is established through a combination of fine-needle aspiration, core needle biopsy, and advanced imaging techniques. Standard treatment involves a multimodal strategy of chemotherapy, often with the addition of radiotherapy and surgical intervention. Herein presented is the first reported case of diffuse large B-cell lymphoma treated with Pola-R-CHP. [ABSTRACT FROM AUTHOR]

Purpose: Patients with intraocular silicone oil (SO) display higher odds of surgical failure after Ahmed glaucoma valve (AGV) implantation compared to patients without SO. However, the structural impact of SO exposure on silicone-made AGV tubes and the resulting changes in flow rate remain unexplored. This in-vitro study evaluated changes in tube dimensions and flow rates of AGV FP7 tubes after SO exposure to inform clinicians how such changes may impact AGV functionality. Methods: AGV FP7 tube segments underwent accelerated aging to approximate 90 days of exposure to the following media: Balanced Salt Solution (BSS), 1000 centistokes (cs) SO, and 5000cs SO. Tube dimensions were measured before and after aging. A constant gravity flow test setup was created to measure flow rates through tubes before and after aging. The students' T-test was used to compare the mean change between groups post-aging. Results: Post-exposure, 1000cs and 5000cs SO tube segments increased in length by 5.94% and 5.55%, respectively, compared to 0.38% of BSS tubes (P < 0.05 for both). The inner lumen area expanded for tube segments in 1000cs and 5000cs SO by 11.75% and 2.70%, respectively, but contracted for tubes in BSS by -2.70% (P < 0.01 and P = 0.068 for 1000cs and 5000cs SO, respectively). Post aging, the flow rates increased on average by 61.0% and 98.6% for 1000cs and 5000cs SO, respectively, whereas flow rates for BSS tube segments slightly decreased by -4.92%. The difference was statistically significant for BSS vs. SO groups (P < 0.01 for both). Conclusions: Prolonged exposure to SO structurally altered the AGV FP7 tube segments by expanding their cross-sectional area, potentially leading to increased flow rates. These results may inform clinicians about potential in-vivo interactions in patients with the simultaneous presence of glaucoma drainage devices and intraocular SO. [ABSTRACT FROM AUTHOR]

The worldwide population growth and its increasing affluence have led to an increase in global building energy consumption. Therefore, developing sustainable energy storage materials to mitigate this problem has become a high priority for many researchers. Organic phase change materials (PCMs), such as fatty acids, have been extensively studied for thermal energy storage in building applications due to their excellent performance in absorbing and releasing energy within the environment temperature ranges. However, issues related to their thermal conductivity, stability, and flammability could limit the potential and require addressing. In this review, organic PCMs, with a special focus on fatty acids, are discussed. This review covers recent studies related to PCM synthesis from bio-sources, methods for PCM incorporation in building materials, methods for enhancing organic PCM thermal properties, flammability challenges, and life cycle assessment. Finally, future opportunities are summarized. [ABSTRACT FROM AUTHOR]

Objective: More than 95% of melanomas in Australia are caused by UV radiation from the sun. Young adults are particularly at risk, with 18–24-yearolds spending more time in the sun and protecting their skin less than older adults. A new mass media campaign was delivered in New South Wales, Australia, to motivate this hard-to-reach group to protect their skin from harmful UV radiation. This paper shares learnings from this campaign for public health educators working across diverse fields. Program: Guided by audience research and testing, the campaign combined fear-based and self-efficacy messaging. UV radiation was portrayed as arrows descending from the sky, transforming it into a visible and ever-present threat. High-reach channels such as cinema, outdoor advertising, online videos, audio apps and social media were used to reach the audience. Methods: The campaign was evaluated through an online tracking survey (n = 750, 18–24-year-olds) measuring prompted recognition, message take-out, key diagnostics, and self-reported sun protection intentions and behaviours. Results: The evaluation found that 57% of survey participants recognised the campaign when prompted. Among those that recognised the campaign, 76% said they had used sun protection when outdoors over the summer campaign period (vs 64% of non-recognisers, p < 0.05), and 45% said they had adopted at least three of the five sun protection behaviours (Slip, Slop, Slap, Seek and Slide) ‘always’ or ‘often’ (vs. 36% of non-recognisers, p < 0.05). Lessons learnt: A mass-media campaign that aimed to elicit emotional (fear) and cognitive (perceived efficacy) responses and which drew upon social and heuristic cues was associated with greater self-reported sun protection among the target audience. Delivering a combination of message strategies simultaneously within a campaign tailored to young adults may be more effective than adopting a more singular focus. [ABSTRACT FROM AUTHOR]

This article draws on psychoanalytic theory to reconsider democracy, education and their relationship. The author argues for the pervasive presence of fantasmatic thinking in relation to both democracy and education in much media and policy discussion, which fuels our subjection to ideology through cruelly optimistic promises about the future benefits which will accrue from current sacrifice -- promises which are exposed as false by persistent and growing economic inequality and the substantial failure to fulfil its inflated promises that is endemic to modern education. By contrast, the article argues for a politics grounded in an acceptance of constitutive lacking status as desiring subjects, which recognises and embraces the enjoyment that comes from loss, thereby freeing us from the spell of compulsive repetition reflected in our fixation on fantasmatic programmes of redemption in both politics and education. This might open possibilities for realising, albeit indirectly and obliquely, the goals which continually escape our more overt attempts to grasp them. The author's overall argument is that the flaws and illusions characterising our experiences of democracy and education are not reasons to abandon them, but instead suggest a need to rework our relationship to them in less fantasmatic ways, 'in spite of it all'.

Gas hydrate plugs in petroleum fluid pipelines are a major flow assurance problem and thus, it is important for industry to have reliable mathematical models for estimating the time required to dissociate a hydrate pipeline plug. The existing mathematical models for modelling hydrate plug dissociation treat the problem as a pure heat transfer problem. However, an early study by Jamaluddin et al. speculated that the kinetics of gas hydrate dissociation could become the rate-limiting factor under certain operating conditions. In this short communication, a rigorous 2D model couples the equations of heat transfer and fluid flow with Clarke and Bishnoi's model for the kinetics of hydrate dissociation. A distinguishing feature of the current work is the ability to predict the shape of the dissociating hydrate–gas interface. The model is used to correlate experimental data for both sI and sII hydrate plug dissociation, via single-sided depressurization and double-sided depressurization. As a preliminary examination on the necessity of including dissociation kinetics, this work is limited to conditions for which hydrate dissociation rate constants are available; kinetic rate constants for hydrate dissociation are available at temperatures above 273.15 K. Over the range of conditions that were investigated, it was found that including the intrinsic kinetics of hydrate dissociation led to only a very small improvement in the accuracy of the predictions of the cumulative gas volumes collected during dissociation. By contrast, a sensitivity study showed that the predictions of hydrate plug dissociation are very sensitive to the value of the porosity. Thus, it is concluded that unless values of the thermophysical properties of a hydrate plug are known, accounting for the dissociation kinetics need not be a priority. [ABSTRACT FROM AUTHOR]

Batteries are the lynchpin of electric vertical takeoff and landing (eVTOL) aircraft, and the high discharge rates pose a critical challenge to the battery thermal management system (BTMS). This work presents a channeled liquid cooling technology-based BTMS for eVTOL aircraft. During the flight, the heat generated from the batteries is partly extracted by circulating liquid coolant within a wavy channel (WC) attached firmly to the battery cells. The heat is then transported into a plate-fin compact heat exchanger (HEX), where all the heat is dissipated into the atmosphere. We report sensitivity analyses of the HEX model to shed light on the impact of the relevant design parameters on the BTMS size, weight, and power. We also examine critical parameters of the coupled WC-HEX BTMS in a one-dimensional off-design analysis. We demonstrate that the liquid cooling system can maintain the battery operating temperature within acceptable levels with a mass of less than 20% of the battery pack mass. Battery degradation using the liquid cooling system is reduced by over three times compared to an air-cooled system for both tilt-wing and lift+cruise eVTOL aircraft. [ABSTRACT FROM AUTHOR]

2016 marks the centenary of "Democracy and Education", in which Dewey argued for the mutually dependent relationship linking a legitimate education system and a thriving democracy. A century later, it seems, democracy and education have been decoupled, with both undermined by developments such as growing inequality, declining participation and trust in democratic processes, technorationalism that reframes political issues in terms of efficiency, and growing political extremism. Meanwhile, recent years have seen the increasing grip of market-based principles and techniques of measurement and evaluation as stateendorsed norms across various sectors and domains of society, including education, reflecting an instrumentalism Lacan described in terms of 'the service of goods'. Against this background, this paper draws on resources from political and psychoanalytic theory to rethink and reanimate the links between education and democracy, thereby encouraging and emboldening educators to, in David Harvey's words, "write the poetry of their own future".
