- ItemFractional order induced bifurcations in Caputo-type denatured Morris–Lecar neurons(Elsevier B V, 2025-11-01) Ghosh I; Fatoyinbo HOWe set up a system of Caputo-type fractional differential equations for a reduced neuron model known as the denatured Morris–Lecar (dML) system. This neuron model has a structural similarity to a FitzHugh–Nagumo type system. We explore both a single-cell isolated neuron and a two-coupled dimer that can have two different coupling strategies. The main purpose of this study is to report various oscillatory phenomena (tonic spiking, mixed-mode oscillation) and bifurcations (saddle–node and Hopf) that arise with variation of the order of the fractional operator and the magnitude of the coupling strength for the coupled system. Various closed-form solutions as functions of the system parameters are established that act as the necessary and sufficient conditions for the stability of the equilibrium point. Fractional order systems induce memory effects to excitable cells, thus providing an efficient and biophysically more realistic scenario. All theoretical analyses in this study are supported by rigorous numerical simulations.
- ItemReflexive thematic analysis and men's embodiment following injury or illness: A worked example(Wiley Periodicals LLC on behalf of American Association for Anatomy, 2025-05-28) Terry G; Hayfield NReflexive thematic analysis (reflexive TA) originated within psychology and the social sciences and has become an increasingly popular qualitative analytic method across a range of disciplines. In this article, we offer a brief methodological guide for researchers hoping to use the method, suitable for beginners through to those experienced in qualitative research. Reflexive TA can be used to analyze data generated via a range of methods. Reflexive TA is highly flexible, and we outline the choices that researchers need to address when conducting their research. These choices relate to the theoretical approach (realist through to relativist/experiential to critical), their orientation to analyzing the data (inductive to deductive), and the depth in which they analyze their dataset (semantic to latent). We offer an accessible but comprehensive discussion of the six phases of reflexive thematic analysis and how best to produce a rigorous analysis. Starting with familiarization of the dataset as a foundation for analysis, data are then coded, before using these codes to generate initial themes. These early themes are then reviewed and developed, before the researcher moves to defining and naming them. The final phase of analysis is the writing up of the research, at which point final changes may still be made to the results. Written from the basis of our experience of using, teaching, and training reflexive thematic analysis within psychology and the social sciences, we see it as useful for those working across a range of disciplines.

- ItemUnderstanding the evolution of scoria cone morphology using multivariate models(Springer Nature Limited, 2025-06-06) Kereszturi G; Grosse P; Whitehead M; Guilbaud M-N; Downs DT; Noguchi R; Kervyn MScoria cones are the most abundant type of volcano in the Solar System. They occur in every tectonic setting and often overlap with human populations, yet our ability to provide complete geochronology within volcanic fields remains limited. Appropriate geochronology underpins the reconstruction of size-frequency distribution and is a key input for robust volcanic hazard assessment. Morphometric data have long been used to estimate relative ages of scoria cones; however, they have only shown promise at single volcanic fields and simple cones with homogenous pyroclastics. Here, we present a new global inventory of dated scoria cones (n = 572) from 71 volcanic fields formed under diverse magmatic, tectonic and climatic regimes, and build data-driven age models for dating scoria cones using easily accessible morphometric, reflectance and climatic variables. Our models suggest chemical composition of ascending magma may influence the initial scoria cone morphology which is then gradually modified by erosion over time. (Figure presented.)

Method: Poisson regression models within a discrete-time survival framework were constructed using web-based self-report survey data from 72,288 incoming university students across 18 countries (response rate=20.9%; median age=19 years, 57.9% female, 1.4% transgender, 21.0% non-heterosexual). These models examined the associations of four demographic variables, five CAs, and eight MDx with STB outcomes. Results: Lifetime prevalence of suicidal ideation, plans, and attempts was 47.0%, 26.0%, and 9.6%, respectively; 12-month estimates were 30.6%, 14.0%, and 2.3%. In unadjusted analyses, associations were strongest between lifetime onset of suicidal ideation and CAs (RR range 4.4–7.0), particularly parental psychopathology (relative risk [RR]=7.0 [95% CI 6.5–7.7]), followed by MDx (RR range 1.3–3.0). Of the demographic subgroups, transgender students had highest risk of STB (lifetime ideation onset RR=2.4 [2.3–2.6]; ideation-to-attempt transition RR=1.5 [1.3–1.8]). In fully adjusted models, strongest predictors of lifetime ideation onset were emotional abuse (RR=2.1 [1.9–2.2]), major depressive disorder (RR=2.0 [1.9–2.1]), and bipolar disorder (RR=1.8 [1.6–2.0]). Ideation-to-attempt transition remained most strongly associated with panic disorder (RR=1.5 [1.3–1.7]), bipolar disorder (RR=1.4 [1.2–1.7]), and sexual abuse (RR=1.4 [1.2–1.7]). Most predictors were significantly but weakly associated with persistence of ideation and plan, while only physical abuse remained associated with repeated suicide attempts (RR=1.3 [1.0–1.8]). Conclusion: CAs and MDx are strong predictors of both onset of and transition within the STB spectrum, underscoring the importance of implementing early-life prevention interventions.

- ItemSME employee perceptions about future work–life flexibility: findings from New Zealand(Taylor and Francis Group, 2025-06-17) Scott J; Macpherson W; Tootell B; Kobayashi K; Kelly SEmployees of New Zealand small and medium enterprises (SMEs) desire more work–life flexibility and are seeking change in the workplace. Applying institutional theory and the related concept of institutional work as our theoretical frame, we explored employee perceptions about working arrangements and found a substantial desire for change. Specifically, 71% of 619 employees surveyed wanted more work–life flexibility, with the research highlighting three constructs that contribute to employee perceptions about their work and nonwork interface: working pattern control, job flexibility, and a sense of being respected. The findings are significant and novel as they illustrate a renewed desire on the part of employees to change work arrangement practices in response to recent lived experiences. Given these demands for flexibility are now being driven from an employee rather than employer perspective, this could lead to the development of new normative expectations that would place pressure on SMEs to change work arrangements in response to employees’ active agency. In current high-employment environments, employee flexibility is likely to facilitate a recruitment and retention advantage, and each of the identified constructs will potentially play a fundamental major role in employee–employer relationships.
- ItemBack to the future with old-fashioned conversations: Building relationships and individualising support with educational technologies(Australasian Society for Computers in Learning in Tertiary Education, 2018-01-01) Heinrich E; McDonald J; Campbell M; Willems J; Adachi C; Blake D; Doherty I; Krishnan S; Macfarlane S; Ngo L; O’Donnell M; Palmer S; Riddell L; Story I; Suri H; Tai JRecent advances in ICT have had a profound effect on tertiary education. However, critical and social theorists caution that the relationship between teacher and student is still central and educational research over many years suggests that some of the most successful pedagogical methods are those which strengthen the relationship between teacher and student and which support student development of relatedness, competence and autonomy. In this paper, we propose a new approach to course design and organisation which builds on lessons from the past while taking advantage of the affordances of contemporary technology. We summarise data from interviews with teachers and learning support staff and conclude with our hopes for the future.
- ItemEnhancing antioxidant property of instant coffee by microencapsulation via spray drying(EDITORIAL UNIVERSITAT POLITÈCNICA DE VALÈNCIA, 2018) Sakawulan D; Archer R; Borompichaichartkul CThis study is aimed to improve the antioxidant property of instant coffee by using microencapsulation technique and spray drying. Concentrated coffee extract was mixed with Konjac glucomannan hydrolysate (KGMH) and Maltodextrin (MD). The mixture of coating material and coffee extract was then spray dried at 160 - 180 °C inlet air temperature and at 85-90 °C outlet air temperature. KGMH can preserve retention of phenolic compounds, DPPH scavenging activity and antioxidant activity of FRAP (p<0.05) of instant coffee better than other treatment.
- ItemMicrofibres and health: State of the evidence and research gaps(Elsevier B V, 2025-08-01) Taptiklis P; Boulic M; Phipps R; van Heerden H; Shaw CMicrofibres are ubiquitous in the environment and there has been an increasing focus on health harms from them in recent decades. The current WHO guidelines defining health risks from microfibres focus on just the subset of microfibres that are inorganic and respirable. Recent studies have revealed large volumes of textile microfibres are present throughout the environment and that non-plastic microfibres are as common or more common than plastic microfibres. However, these are rarely included in the analysis of harms. This narrative review of textile microfibres sets out the state of our understanding of exposure to and harms from textile microfibres. We found that the epidemiological research reviewed here does not support the continued focus solely on the respiratory route of exposure nor only on plastic microfibres as hazardous to health. In fact, gastrointestinal as well as upper airway effects may also be increased by exposure to textile microfibres. Importantly, microfibres behave differently in the environment, and within the body in comparison to non-fibre particles, and therefore warrant separate investigation from particles and microplastics. The conclusion of this cross-disciplinary review is an urgent call for greater investigation of textile microfibres, separately from the also important issue of microplastics, and therefore, the inclusion of non-plastic fibre types in research going forward.
