The ‘Good Kiwi’ and the ‘Good Environmental Citizen’?: Dairy, national identity and complex consumption-related values in Aotearoa New Zealand
Authors: Sharp E. L. , Rayne A. , Lewis N. 
Published: March 2024

AbstractAlongside concerns for animal welfare, concerns for land, water, and climate are undermining established food identities in many parts of the world. In Aotearoa New Zealand, agrifood relations are bound tightly into national identities and the materialities of export dependence on dairying and agriculture more widely. Dairy/ing identities have been central to national development projects and the politics that underpin them for much of New Zealand’s history. They are central to an intransigent agrifood political ontology. For the last decade, however, they have been challenged by the identity politics of ethical food consumption. This paper explores the ensuing contests and asks how they are reshaping agrifood identities. We draw on interviews with 15 participants in Aotearoa New Zealand who have made dietary transitions that reduce or exclude dairy products. Our aim is not to identify a new post-dairying identity or claim a reconfigured national identity, but to examine the collision of production-consumption values in the context of a dominant place-based food identity. We ask how participants navigate contradictory commitments to becoming ‘good environmental citizens’ whilst remaining ‘good national citizens’. The paper offers insights for examining similar struggles elsewhere and the potential to shift agrifood relations and undermine entrenched political ontologies through ethical food consumption values.

AbstractAdding a reinforced stucco layer to the masonry infill walls is a preferred method for strengthening RC frame system structures with an easy-to-apply method that does not require a long time, is economical, and does not require detailed and extensive workmanship. However, no research has been discovered as a result of the extensive literature review that investigates the effects of masonry-infilled RC frames strengthened with a reinforced stucco layer on the seismic performance of openings that must be due to architectural requirements such as doors, windows, installations, and similar ventilation systems. As a result, an experimental study was planned to investigate the effects of the dimensions and location of the opening in the masonry infill walls on the performance of the strengthening method with the reinforced stucco layer. The applied strengthening method increased the ultimate load capacity, initial stiffness, and energy dissipation capacity values of reinforced concrete frames with masonry infill walls by 83%, 226%, and 62%, respectively, but resulted in a 38% decrease in displacement-ductility ratios. The study found that the openings in the masonry infill walls harm the performance of the strengthening technique by adding a rebar-reinforced stucco layer and decreasing the success level. When the opening size increased, and the opening was located at the corner of the masonry wall, the performance of the applied strengthening technique was negatively affected and decreased. Furthermore, nonlinear numerical analyses of the experiments conducted as part of the study were performed using ABAQUS finite element software. The numerical analysis results were compared to the experimental results. It has been determined whether numerical analysis models are compatible with experimental results.
Prey killing rate of a generalist predator may be enhanced by macronutrient manipulation

Published: March 2024

AbstractGeneralist arthropod predators forage not only to gain energy and nutrients, but also to obtain a balanced intake of macronutrients (the intake target). We test two opposite hypotheses concerning the predation rate of nutritionally imbalanced predators: It will increase (1) if the prey is rich in macronutrients that the predator is short of, or (2) if the prey is low in macronutrients that the predator is short of. We used the wolf spider Pardosa amentata (Clerck) as the predator and nutritionally manipulated Drosophila melanogaster Meigen as prey. We completed a full factorial experiment with eight treatment groups, in which we measured predation, consumption and prey utilization of high-protein (HP) and high-lipid (HL) flies by spiders that were previously treated with either HP- or HL-flies for two or six days. The results supported hypothesis 2. Whether spiders had been previously fed HP-or HL-flies, those that were tested against the same type of fly killed more than those tested against the opposite type of fly. A likely explanation for this result is that the predator will be unable to reach its macronutritional intake target by continued feeding on the same prey. It will stay nutritionally imbalanced and continue to catch prey in an attempt to redress its imbalance. In natural systems, predation rates may thus be increased by the widespread mismatch between predators’ nutritional demands and what is available in prey. In practical biological control, it suggests a beneficial effect of feeding the predator prior to release with the pest it is intended to control.
Orbital dynamics of smart dust with Poynting–Robertson and solar wind drag
Authors: Vadlamani Vinayak , Gurfil Pini 
Published: March 2024

AbstractSmart dust devices are tiny systems-on-a-chip platforms capable of sensing, storing and transmitting data wirelessly as part of a large network with distributed capabilities. Previous works investigated the long-term orbital evolution of smart dust in space by studying the combined effect of gravitational perturbations, solar radiation pressure (SRP) and atmospheric drag. In the current work, the problem of finding long-term orbital equilibria conditions for smart dust is recast and extended to include Poynting–Robertson and Solar Wind (PRSW) drag. By including the PRSW effects and defining new equilibrium conditions on the orbital orientation, some additional partial equilibrium solutions are found. Moreover, it is shown that even though PRSW is not dominant compared to SRP or $$J_2$$

J

, it still influences the evolution of the relative Sun-orbit orientation. For orbits with higher initial perigee altitudes, where drag and $$J_2$$

effects subside, it is shown that PRSW influences long-term orbital behavior, and should be considered in the orbit design scheme of smart dust devices.
Exploring Heparan Sulfate Proteoglycans as Mediators of Human Mesenchymal Stem Cell Neurogenesis

Published: March 2024

AbstractAlzheimer’s disease (AD) and traumatic brain injury (TBI) are major public health issues worldwide, with over 38 million people living with AD and approximately 48 million people (27–69 million) experiencing TBI annually. Neurodegenerative conditions are characterised by the accumulation of neurotoxic amyloid beta (Aβ) and microtubule-associated protein Tau (Tau) with current treatments focused on managing symptoms rather than addressing the underlying cause. Heparan sulfate proteoglycans (HSPGs) are a diverse family of macromolecules that interact with various proteins and ligands and promote neurogenesis, a process where new neural cells are formed from stem cells. The syndecan (SDC) and glypican (GPC) HSPGs have been implicated in AD pathogenesis, acting as drivers of disease, as well as potential therapeutic targets. Human mesenchymal stem cells (hMSCs) provide an attractive therapeutic option for studying and potentially treating neurodegenerative diseases due to their relative ease of isolation and subsequent extensive in vitro expansive potential. Understanding how HSPGs regulate protein aggregation, a key feature of neurodegenerative disorders, is essential to unravelling the underlying disease processes of AD and TBI, as well as any link between these two neurological disorders. Further research may validate HSPG, specifically SDCs or GPCs, use as neurodegenerative disease targets, either via driving hMSC stem cell therapy or direct targeting.
Graphical Abstract
Graphical abstract: Heparan sulfate proteoglycans as regulators of human mesenchymal stem cell neurogenesis. Traumatic brain injury (TBI) and genetic factors increase Alzheimer’s disease (AD) risk (yellow). Potential AD treatment targets (green) include human mesenchymal stem cells (hMSCs). Manipulating pathway and growth factor interactions with heparan sulfate proteoglycans (HSPGs) could regulate hMSC neurogenesis, potentially offering functional neural stem cell transplants as AD treatments
“Mathematics is a battle, but I’ve learned to survive”: becoming a disabled student in university mathematics
Authors: Nieminen Juuso Henrik , Reinholz Daniel L. , Valero Paola 
Published: March 2024

AbstractIn university mathematics education, students do not simply learn mathematics but are shaped and shape themselves into someone new—mathematicians. In this study, we focus on the becoming of disabled mathematical subjects. We explore the importance of abilities in the processes of being and becoming in university mathematics. Our interest lies in how teaching and assessment practices provide students with ways to understand themselves as both able and disabled, as disabilities are only understood with respect to the norm. We analyse narratives of nine university students diagnosed with learning disabilities or mental health issues to investigate how their subjectivity is constituted in discourse. Our analysis shows how the students are shaped and shape themselves as disabled mathematicians in relation to speed in mathematical activities, disaffection in mathematics, individualism in performing mathematics, and measurability of performance. These findings cast light on the ableist underpinnings of the teaching and assessment practices in university mathematics education. We contend that mathematical ableism forms a watershed for belonging in mathematics learning practices, constituting rather narrow, “normal” ways of being “mathematically able”. We also discuss how our participants challenge and widen the idea of an “able” mathematics student. We pave the way for more inclusive futures of mathematics education by suggesting that rather than understanding the “dis” in disability negatively, the university mathematics education communities may use dis by disrupting order. Perhaps, we ask, if university mathematics fails to enable accessible learning experiences for students who care about mathematics, these practices should indeed be disrupted.
On icicle ripples
Authors: Worster M. Grae 
Published: March 2024

AbstractNatural icicles have an overall conical shape modulated by surface ripples. It has been noted from many observations of icicles formed in nature and in the laboratory that the wavelength of the ripples has a very narrow spectrum between about 8 and 12 mm and that, as time evolves, the phase of the ripples migrates upwards. In this pedagogical review, I explore some of the physical mechanisms that can cause and mediate the formation and migration of ripples on icicles using simple mathematical models. To keep the mathematics more straightforward and transparent, I confine attention to two dimensions. A key physical parameter is the surface tension between the film of water that coats an icicle and the air that surrounds it, which causes a phase shift between the film–air interface and the ice–film interface. I show that the wavelength of ripples is dominantly proportional to the cube root of the square of the gravity-capillary length times the thickness of the water film. At high film-flow rates, advection-dominated heat transfer coupled with the interfacial phase shift becomes the dominant driver of instability. Gibbs–Thomson undercooling provides an unexpectedly large stabilisation of small wavelengths at these large flow rates, sufficient to maintain wavelength selection at millimetre scales.
Should We Increase Young People’s Voting Power?
Authors: Angell Kim 
Published: March 2024

AbstractThis paper argues that democratic collectives have reason to increase the voting power of their younger members. It first presents an intuitive case for weighted voting in general, before drawing support from a prominent principle of democratic inclusion – the all-affected principle. On a plausible understanding of that principle, a decision may affect people to varying degrees, and this variation should be reflected in the strength of their say. The paper then argues that exposure time to a decision’s effects is typically a good proxy for tracking such variation, such that collectives have reason to gradually reduce their members’ voting power as they grow older. This holds, for example, in the ordinary parliamentary elections in representative democracies. It is then argued that we may build a similar case for age-weighting on a plausible version of the all-affected principle’s main rival, the all-subjected principle. The paper ends by addressing various objections. It argues that none of them undermine the case for age-weighting, and that some might even support age-weighting over its non-weighted (‘one person, one vote’) alternative.
Clinician perspectives on policy approaches to genetic risk disclosure in families

Published: March 2024

AbstractGenomic sequencing has emerged as a powerful tool with significant implications for patients and their relatives, however, empirical evidence suggests that effective dissemination of risk information within families remains a challenge. Policy responses to address this issue vary across countries, with Belgium notably lacking specific regulations governing nondisclosure of genetic risk. In this study, we conducted semi-structured interviews with clinicians from Belgian clinical genetics centers to gain insight into their perspectives on policy approaches to the disclosure of genetic risk within families. Using real-world examples of legislation and court rulings from France, Australia, and the UK, we explored clinician viewpoints on the roles and responsibilities of both patients and clinicians in the family communication process. Clinicians expressed confusion regarding what was legally permissible regarding contacting at-risk relatives. While there was a consensus among participants that patients have a responsibility to inform their at-risk relatives, participants were hesitant to support the legal enforcement of this duty. Clinicians mostly recognized some responsibility to at-risk relatives, but the extent of this responsibility was a subject of division. Our findings highlight the need for a comprehensive policy that clarifies the roles and responsibilities of clinicians and patients to inform at-risk relatives. Furthermore, the study underscores the practical challenges clinicians face in supporting patients through the complex process of family communication, suggesting a need for additional resources and the exploration of alternative approaches to communication.
Podcasting for Public Knowledge: A Multiple Case Study of Scholarly Podcasts at One University

Published: March 2024

AbstractThrough a lens for engaged scholarship (Boyer in Journal of Public Service and Outreach, 1(1), 11–20, 1996) this multiple case study (Merriam, 1996) explores the potential of scholarly podcasts for public knowledge dissemination, highlighting the misalignment of university impact metrics with this medium. Our team collected qualitative and numerical data from six podcasters across our university system. We identify metrics for assessing scholarly podcast value, offer recommendations for institutional communication, and share our insights and challenges. Data analysis suggests that a Listen Score (Listen Notes, ND) and an increasing Podcast Success Index (Singh et al. JMIR Medical Education, 2(2), 1–10, 2016) may be consistent with a wider reach. Consistent production and promotion are key and infrastructure support for scholarly podcasters is necessary.
Reconciling Ireland’s climate ambitions with climate policy and practice: challenges, contradictions and barriers
Authors: Slevin Amanda , Barry John 
Published: March 2024

AbstractOften perceived as a green nation, Ireland’s climate action reputation ranges from being regarded as a climate ‘laggard’ to being applauded as one of the first states to introduce supply-side ‘keep it in the ground’ (KIIG) legislation. In line with UNFCCC and IPCC advice, Ireland has committed to reducing greenhouse gas (GHG) emissions by 51% by 2030 and reaching net zero by 2050. However such ambitions have not yet translated into sufficient transformations required to achieve the goals of a Paris Agreement compliant pathway. Major challenges surround Ireland’s transition to net zero, for example, the country’s fossil fuel dependency means oil and gas (mostly imported) account for around 80% of primary energy while emissions from agriculture, transport and electricity generation are increasing, rather than decreasing. Ireland is failing to meet national and EU GHG reduction targets, has had to buy emissions quotas to comply with legal requirements, and its interim 2030 target is below the EU’s Climate Law ambition. Contradictory policies, especially those influenced by ROI’s neoliberal orientation, undermine climate action and mean Ireland struggles to achieve GHG reductions, despite the state’s climate change legislation and policies. Concentrating on supply-side climate policy, this article examines key issues hampering Ireland’s ability to reconcile its climate ambitious with policy and practice. Adopting a critical political economy analysis, we explore multi-level drivers of climate and energy policies, examining challenges like the war in Ukraine, which prompted the Irish state to re-consider where and how it sources gas and oil, in turn threatening existing KIIG measures. In critically analysing challenges and contradictions, we identify multiple ideological, political and economic factors, in particular, the neoliberal, globalised economic model influencing the State’s current unsustainable, risky and contradictory policy direction. We conclude by articulating specific barriers hampering Ireland’s climate ambitions that must be addressed to enable a just transition to a sustainable future.
The Behavioral Education in Social Media (BE-Social) Program for Postgraduate Academic Achievement: A Randomized Controlled Trial
Authors: Tarifa-Rodriguez Aida , Virues-Ortega Javier , Calero-Elvira Ana 
Published: March 2024

AbstractFew randomized controlled trials have evaluated social media study groups as educational aids in the context of online and blended teaching programs. We present the Behavioral Education in Social Media (BE-Social) intervention package, which integrates key evidence-informed behavioral intervention strategies delivered through a closed social media study group. BE-Social combines instructor-mediated cooperative learning and self-management training via multimedia posts and video modeling. Forty-six students were randomly assigned to a default online program (control) group or default online program plus BE-Social (intervention) group. Intervention outcomes included academic performance and social media engagement (reactions, comments). A mixed-effect ANOVA showed that individuals in the BE-Social group attained higher academic performance, F (1, 46) = 18.37, p < .001, η2 = .34). On average, the intervention produced a 20-point increase in academic performance over a 100-point scale and significant increases in social media engagement. A parallel single-subject analysis revealed that intervention gains were not always consistent across participants. Findings are consistent with the view that social media platforms provide a prosthetic social milieu that can enrich traditional education by maximizing social rewards through increased interaction opportunities and timely positive feedback. We propose the digital environment reward optimization hypothesis to denote these processes.
Subsidies or green taxes? Evaluating the distributional effects of housing renovation policies among Dutch households
Authors: Fernández Alejandro , Haffner Marietta , Elsinga Marja 
Published: March 2024

AbstractDespite persistent housing affordability issues, energy policy and housing renovation are usually investigated separately from housing costs other than energy. Researchers have examined the financial viability of renovation attending to building conditions and the socio-economic characteristics of their occupants. However, the distributional impacts of renovation incentives and the potential of fiscal policy to redistribute housing costs remain understudied. Dutch fiscal policy, favouring homeownership, offers a relevant context to evaluate how property taxation can boost renovation rates. The novelty of this paper resides in investigating the impact of two policies, the current direct subsidy and a proposal for a green tax, on both the financial viability of renovation and the subsequent distribution of housing costs. The proposed green tax combines energy efficiency and taxation of property revenue. We employ a model considering marginal costs of housing renovation, obtained from a government dataset, and marginal benefits, drawn from a hedonic regression. We assess the distributional impacts of different policy scenarios by examining changes in user costs across income deciles. Our findings indicate that existing renovation subsidies exacerbate the regressive distributional impacts resulting from the current housing taxation system in the Netherlands. Introducing energy-efficiency-linked property taxation can make homeownership fiscality less regressive while incentivising housing renovation. Ultimately, this study highlights the importance of incorporating housing affordability as a fundamental element in renovation policies to balance environmental and distributional objectives.
