Infrared measurements of fluid temperature in a polymeric Pulsating Heat Pipe

Pulsating heat pipes are two-phase passive heat transfer devices partially filled with a working fluid in saturation conditions. During operation, supplying heat to one end of the system (named evaporator) results in a local increase in temperature and pressure, which drives the fluid through a transport section (named adiabatic section) towards the cooled, opposite end (named condenser) for effective heat dissipation. The local thermo-fluid dynamic state of the working fluid is sometimes assessed by means of non-intrusive techniques, such as infrared thermography. In this case, the radiative properties of the systems in the infrared spectrum must be known a priori. Nevertheless, since pulsating heat pipes may be manufactured with different materials, wall thicknesses and channel geometries, the radiative properties of the walls and the confined flow are not always known or assessable by means of the available literature. Hence, the work proposes to design a straightforward calibration procedure for quantitative infrared fluid temperature measurements in a polymeric pulsating heat pipe charged with FC-72 and having unknown radiative properties. The emissivity and transmissivity of the walls and confined fluid are estimated with good accuracy. The results will allow repeatable and reliable fluid temperature measurements in future experimentations on the mentioned device

The importance of safe, brave and facilitated spaces in student-staff partnerships - Finding a space for compassion

This study focuses on the importance of having a safe space, brave space and a facilitated space in student-staff partnerships. The importance of having a facilitated space of drop-ins and workshops supporting students pastorally was investigated as part of an initiative called the Inclusive Practice Partnerships (IPP) Scheme, drawing on compassionate pedagogies. Healey et al.’s partnership framework is used as a conceptual lens to inform analysis. Semi-structured in-depth interviews were conducted with students and staff to investigate their experiences of attending facilitated drop-in and workshop sessions and how this enhanced their overall experience of partnership. Thematic cross-sectional content analysis of the interview data was conducted adopting pre and open coding. Findings highlight the importance of wellbeing support, sharing experiences, building resilience and providing personal development opportunities. Discussion and recommendations from the findings are shared to inform practitioners seeking to develop support for students working in partnership in colleges and universities in national and international contexts

Building Heroes:building bridges to support the transition from military to civilian employment in the construction industry

PurposeMany veterans struggle with the civilian world and the loss of identity associated with leaving the service. This research investigates the Building Heroes Charity's role in assisting service leavers transitioning to civil employment, in the United Kingdom (UK) and what can be learnt from the training and support.Design/methodology/approachAn exploratory case study design was chosen to investigate the transition from military to civilian employment. The case study consisted of 12 in-depth interviews consisting of nine veterans, who had attended the Building Heroes courses and three course tutors.FindingsThe Building Heroes Charity does have an important role to fulfill in the transition of military personnel from the service to civilian work. There are positive outcomes that complement the work done by the Career Transition Partnership (CTP), but there still needs to be recognition that the needs of veterans do differ by age, transferability of competencies and the financial resources available.Research limitations/implicationsThe limitations of this research are the sample size is small and the majority of the veterans are from the Army. This is mostly because the Army is the largest of the services.Originality/valueThough there is limited research into the employment of veterans, there is evidence to demonstrate that veterans are more likely to suffer from depression and potential homelessness than nonservice personnel. This research is unique in investigating the role of a charity whose main purpose is to improve the employability of veterans by reducing the competency skills gap between the military and construction industry

A practical guide on strategic roadmapping for information and operations technology management:a case study on industry 5.0 transformation

Strategic roadmapping is in realizing strategic visions and driving transformative agendas, but its methodology remains largely underdeveloped, particularly in the context of information and operations technology management. To address this gap, this study proposes a strategic roadmapping methodology to standardize and enhance its applicability in academia and practice. This methodology offers an approach to develop a strategic roadmap, involving defining the roadmap’s vision and boundaries, identifying critical initiatives, establishing priorities and contextual relationships, and highlighting the importance of continuous monitoring and updating. A case study focusing on Industry 5.0 transformation success is utilized to demonstrate the functionality and implications within the information and operations technology management context. The result allows manufacturers to effectively navigate the complexities and disruptions of Industry 5.0, fulfill its core objectives, and ultimately achieve digitalization success

Linguistic auto-poetry:An auto-theoretical approach to the multilingual subject’s self/ves and relationship to language(s)

This paper will explore the contribution auto-reflexive poetry can make to research on multilingualism in literature, or “heterolingualism”, and how heterolingual poetry can be a literary space for expressing the multilingual self/ves. In this regard, I wish to propose a case study of my autobiographical-heterolingual poetry collection, ORCHESTR A.E (AB publishing 2023). This auto-theoretical work addresses my identity as a bilingual person and provides insights into my creative process. My code-switching is motivated not only by lexical differences, but also by how I relate to English and French. I experience languages as more than communicative tools: they are sensory and aesthetic phenomena which elicit various emotions. I am currently working on new bilingual poetry dealing precisely with how I express my feelings and emotions differently in each language. As part of my PhD (The polyglot writer: what multilingual texts reveal about writers’ emotional attachment to the languages they speak), I will draw on existing work from authors such as Suchet and Grutman, Gümüşay and Pavlenko to specify the way polyglot writers identify with the languages they speak, and the cognitive processes behind the choice of language(s) they use in writing. Focusing on auto-reflexive work bears the larger question of whether heterolingual poetry has an inherently autobiographical dimension, a question I aspire to elaborate on as my research advances

Tracking collective emotions in 16 countries during COVID-19:a novel methodology for identifying major emotional events using Twitter

Using messages posted on Twitter, this study develops a new approach to estimating collective emotions (CEs) within countries. It applies time series methodology to develop and demonstrate a novel application of CEs to identify emotional events that are significant at the societal level. The study analyzes over 200 million words from over 10 million Twitter messages posted in 16 countries during the first 120 days of the COVID-19 pandemic. Daily levels of collective anxiety and positive emotions were estimated using Linguistic Inquiry and Word Count's (LIWC) psychologically validated lexicon. The time series estimates of the two collective emotions were analyzed for structural breaks, which mark a significant change in a series due to an external shock. External shocks to collective emotions come from events that are of shared emotional relevance, and this study develops a new approach to identifying them. In the COVID-19 Twitter posts used in the study, analysis of structural breaks showed that in all 16 countries, a reduction in collective anxiety and an increase in positive emotions followed the WHO's declaration of COVID-19 as a global pandemic. Announcements of economic support packages and social restrictions also had similar impacts in some countries. This indicates that the reduction of uncertainty around the evolving COVID-19 situation had a positive emotional impact on people in all the countries in the study. The study contributes to the field of CEs and applied research in collective psychological phenomena

Inoperativity as a form of Refusal:On Bonnie Honig’s Reading of Agamben

The aim of this article is to follow Honig’s intention of thinking inoperativity as a form of refusal. It demonstrates that Agamben’s inoperativity entails an intensification of use that can circumvent the pitfalls associated with the language of ‘demands,’ or the need to rescue the city as the space of the political par excellence, all while preserving its potential for instituting change. I claim that all destitution entails instituting practices and forms of experimentation that modify the subject, and that, with the help of Agamben, subjects are nothing other than these modifications. The wager of this short intervention, therefore, is that a form of refusal that pays critical attention not only to the act of suspension or negation, but also to the generative force that this suspension inherently entails is attainable, all while circumventing the city as a political space shaped by anti-blackness

On the Learning, Transmission, and Embodiment of Swimming’s Haptic Grammar

This paper develops the concept of ‘haptic grammar’ to encourage greater scholarly focus on the sensory aspects of bodily motion used to generate movement, knowledge of one’s body in an environment, and thus being-in-the-world. It ethnographically examines how swimmers learn specific motions - ‘the catch,’ sculling, hand entry - to illustrate broader questions of how we learn to move our bodies. Focusing on these specific motions emphasizes the importance of shared sensory knowledge and perception for learning enskilled bodily movement. More than simply knowing what to move when and how, learning how to sense how one moves one’s body parts is a crucial social process that swimmers become more skilful at via interlocutions amongst themselves and with their coaches regarding specific motions of specific body parts. This article illustrates how such socialized knowledge requires a shared haptic grammar to become more skilful at moving through the water and thus become ‘swimmers.
