Experimental investigations on thermo-fluid performance of perforated baffle aided with oppositely oriented sawtooth deflector in tubular heat exchanger
Authors: Rahman Md Atiqur 
Published: August 2024

Purpose
The investigation concentrated on studying a distinct category of tubular heat exchanger that uses swirling airflow over tube bundle maintained at constant heat flux. Swirl flow is achieved using a novel perforated baffle plate with rectangular openings and multiple adjustable opposite-oriented saw-tooth flow deflectors. These deflectors were strategically placed at the inlet of the heat exchanger to create a swirling flow downstream.

Design/methodology/approach
The custom-built axial flow heat exchanger consists of three baffle plates arranged longitudinally supporting tube bundle maintained at constant heat flux. The baffle plate equipped with saw-tooth flow deflector of various geometry represented by space height ratio(e/h). Next, ambient air was then directed over the tube bundle at varying Reynolds number and the effect of baffle spacing (PR), Space height ratio (e/h) and inclination angle(a) of deflectors on performance of heat exchanger was experimentally analyzed.

Findings
The heat transfer augmentation of heat exchanger for given operating condition is strongly dependent on geometry, inclination angle of deflector and baffle spacing.

Originality/value
An average improvement of 1.42 times in thermal enhancement factor was observed with inclination angle of 30°, space height ratio of 0.4 and a pitch ratio of 1.2 when compared to a heat exchanger without a baffle plate under similar operating conditions.
Estimating the value of self‐drive recreation in the remote Kimberley: Sensitivity to multi‐destination trips
Authors: Spencer‐Cotton Alaya , Kragt Marit E. , Burton Michael 
Published: August 2024

AbstractThe remote and iconic Kimberley region, in northern Western Australia, is a contested landscape with growing pressure for different types of land use and development. The region has high biodiversity values and impressive scenery that provide attractive recreation experiences for visitors. We estimate the value of domestic recreation to the region using a travel cost model. Analysis includes two approaches for accounting for multi‐destination trips (MDTs) given travel to remote sites are more likely to include these than shorter trips, and four specifications for the value of travel time. We estimate a total consumer surplus of A$110.34 million annually and find that adjusting travel costs for MDTs using stated survey information produces a better fitting model than using revealed travel information. These findings highlight both the importance of estimating recreation values for use in land use planning in the Kimberley and for improving the travel cost method for remote sites where per‐trip travel costs are high.
Disputes over the figures of the COVID‐19 pandemic: Epistemic diversity, dissemination of science, and political opposition
Authors: Sarrazin Jean‐Paul , Cáceres Carlos F. 
Published: August 2024

AbstractThe health policies imposed by multiple national governments after the emergence of SARS‐CoV‐2 were publicly justified by official figures on the deaths that the new virus would have caused and could cause in the future. At the same time, however, groups of people from different countries expressed their scepticism about those figures. Although they were categorised as ‘anti‐science’, ‘spreaders of misinformation’ or ‘conspiracy theorists’ in some media, many of those sceptics claimed to be based on scientific evidence. This article qualitatively analyses a sample of the content published by sceptics on their social media between 2020 and 2022. More specifically, it examines the shared documents supposedly coming from the scientific community. We find very diverse content ranging from unsubstantiated assumptions to documents produced by prestigious scientists inviting questions about the fatality rates, the mathematical models anticipating millions of deaths, and the real numbers of people who died from COVID‐19. The disputes surrounding the official figures lead us to a reflection about the relationship between, epistemic diversity, the dissemination of science, censorship, and new forms of political opposition. We also touch upon the nature and ethics of scientific controversy in times of a ‘war’ against ‘misinformation’.
Flood resilience: Response of an Australian sub‐tropical riparian rainforest to catastrophic flooding
Authors: Martiniello Léandra , Baker Andrew G. , Grant John Campbell , Palmer Graeme 
Published: August 2024

AbstractRiparian taxa are subject to dynamic, intense, flood‐related stressors, and have evolved traits to persist in this environment. Climate change‐induced intensification of flood regimes pose a threat to these ecosystems, and little is understood about their resilience to this intensification. Following two consecutive major floods (the first flood record‐breaking) along the subtropical coast of eastern Australia in March 2022, we used methods based on persistence (resprouting, seedling recruitment), and floristic structure (height, DBH) and assemblage, to assess the resilience of an old growth riparian rainforest to severe flooding in the 12‐month post‐flooding window. Smallerwoody plants (stems <10 m tall, <30 cm DBH) were the most impacted and were significantly impacted by flooding. Native species richness and plant density (plants/m−2) significantly decreased between before and 3 months post‐flooding, after which they continued to significantly increase to surpass pre‐flood values. Overall, ~35% of taxa exhibited resprouting, ~28% of taxa exhibited seedling recruitment, and ~11% exhibited both resprouting and recruitment. An additional ~21% native taxa were introduced to the site via seedling recruitment, along with 65 invasive species. Model‐based multivariate analysis showed flooding significantly altered community floristics (p = 0.026) at 3 months. At 12 months post‐flooding the community was recovering, becoming more floristically similar to its pre‐flood composition. The riparian rainforest exhibited high resilience to intense flooding. Impact, persistence, and resilience varied amongplots, and the community took 12 months to move into recovery. We found that persistence, and floristic structure and composition weighted against impact were effective measures of ecosystem resilience. In the absence of further consecutive events, mature‐phase riparian rainforests are likely to be structurally and floristically resilient to climate change‐induced amplification of flood regimes. Further studies should build on this framework to include invasive weed species impacts, for a more accurate assessment of impacts.
Civilian behavior on social media during civil war
Authors: Gohdes Anita R. , Steinert‐Threlkeld Zachary C. 
Published: August 2024

AbstractRecent research emphasizes social media's potential for citizens to express shared grievances. In active conflict, however, social media posts indicating political loyalties can pose severe risks to civilians. We develop a theory that explains how civilians modify their online behavior as part of efforts to improve their security during conflict. After major changes in territorial control, civilians should be more likely to post positive content, and more content that supports the winning side. We study social media behavior during and after the siege of Aleppo in November 2016. We match Aleppo‐based Twitter users with users from other parts of Syria and use large language models to analyze changes in online behavior after the regime's retaking of the city. Results show that users in Aleppo post more positive and pro‐Assad content, but only when self‐disclosing their location. The findings have important implications for our understanding of digital communication in civil conflict.
Communication, coordination, and surveillance in the shadow of repression
Authors: Chau Tak‐Huen , Hassan Mai , Little Andrew T. 
Published: August 2024

AbstractCommunication technology helps protesters organize, but also allows the government to monitor and repress their actions. We study this trade‐off in a model where protesters want to show up at the same time and place, but also want to avoid government forces. If leaders of a movement can send messages observed only by other protesters, they can successfully coordinate on a variety of sites and force the government to spread resources thin, helping the success of the movement. If the government always observes the messages too, protesters can do no better than always going to a “focal site” knowing that the government will send all resources there as well, and thus experience higher levels of repression for the sake of coordinating tactics. Intermediate cases where messages are partially observed generate dynamics where new technologies and media that are relatively known to other protesters and not the government are used until the government can reliably infiltrate them and the protesters move on to a new medium. When some protesters are more informed than others, the model can explain protest tactics observed in recent prominent cases like having smaller “parallel” protests at the same time but different location of the main gathering.

Published: August 2024

AbstractObjectivePrior research has revealed impaired inhibitory control as a pivotal factor contributing to smokers' struggle to control smoking impulses. However, few studies focus on enhancing smokers' inhibitory control. This study investigates the potential of social rewards to bolster inhibitory control among smokers and elucidates the underlying mechanisms.MethodsIn Experiment 1, a reward‐based Go/Nogo paradigm assessed error rates and reaction times for 30 smokers exposed to social reward and neutral feedback in distinct contexts (smoking‐related and neutral). Experiment 2 used a modified paradigm, incorporating cognitive load manipulation, to investigate error rates, reaction times, N2, and P3 ERPs among 32 smokers facing social reward and neutral feedback under different cognitive loads (high and low).ResultsSmokers exhibit lower Nogo error rates with social reward feedback; higher error rates occur with smoking cues and high cognitive load; increased N2, P3 amplitudes under social reward versus neutral feedback; low cognitive load enhances P3 amplitude under social reward.ConclusionSocial reward improves smokers' inhibitory control, but this effect weakens with exposure to smoking cues; higher cognitive load further diminishes the enhancement of smokers' inhibitory control by social reward under smoking cues.
Lightening the load for paediatric ITP: The importance of health‐related quality of life

Published: August 2024

In their paper, Klaassen et al. present their findings on the revised Kids ITP Tools (KIT). This important work provides an update to the validated measure for evaluating health‐related quality of life (HRQoL) in children with immune thrombocytopenia (ITP). ITP, an acquired autoimmune disorder, results in thrombocytopenia and places children at risk for significant bleeding. Thankfully, the majority of children with ITP will have a brief disease course and no or mild bleeding symptoms. The rarity of severe bleeding events or the development of chronic disease provides a challenge with regard to clinical trial design, making alternative measures of pharmacological efficacy extremely important.Commentary on: Dhir et al.

Inkblots, Psychotherapy and the Tavistock Clinic
Authors: Sayers Janet 
Published: August 2024

AbstractThe purpose of this article is to recount the early history of the Rorschach's inkblots test in Europe and the USA; its subsequent application in highlighting the ill effects on children of bombing during the Second World War; its wartime use in selecting military personnel; its post‐war use in selecting patients for psychotherapy at the Tavistock Clinic in London and subsequent decline in this use of Rorschach's inkblots in favour of focus on the psychotherapy patient's transference experience of the psychotherapist treating them. The article ends with evidence of interest, beyond psychotherapy, in Rorschach's inkblots and with the implications of this for the author's principal conclusion regarding the value of these inkblots in evoking the free association and conversation crucial to psychotherapy.
Dairy versus non‐dairy cheese texture: Sensory and instrumental contrasts
Authors: Hutchings Scott , Alfante Renna , Jacob Noby , Loveday Simon M. 
Published: August 2024

AbstractWith growing consumer demand for plant‐based products that mimic the eating experience of animal‐based products, there is a need for improvement in instrumental measurements of sensory texture. This study aimed to characterize textural differences between dairy and non‐dairy cheeses, and to investigate whether Large Amplitude Oscillatory Shear (LAOS) rheometry could discriminate sensory texture better than Texture profile analysis. Commercial dairy and non‐dairy cheddar, mozzarella, and cream cheese were selected to provide a wide range of textures. Sensory evaluation used the check‐all‐that‐apply methodology with 73 consumers. Texture profile analysis force‐distance data were analyzed empirically, and also converted to stress and strain (see https://shiny.csiro.au/texture_dash). The major textural differences between dairy and non‐dairy cheddar were related to structural cohesion, according to both instrumental measures (dairy cheddar had 1.5‐fold higher failure stress and 2.2‐fold higher failure strain) and sensory measurements (dairy cheddar was more chewy and less crumbly). In contrast, cream cheeses showed similar textural properties using sensory testing but significant instrumental differences (non‐dairy cream cheese had 5.7‐fold higher modulus of deformability, 4.7‐fold higher failure stress). For mozzarella, there were large differences in both sensory attributes (chewy, crumbly, jelly‐like, stretchy) and instrumental parameters (13.6‐fold difference in modulus, 2.7‐fold difference in failure stress). LAOS rheometry gave insights into the mechanisms by which samples absorbed or dissipated mechanical energy at nonlinear strains. The LAOS parameter correlated well with sensory attributes creamy, fatty/oily, and moist, indicating the potential of this technique to measure structural phenomena linked to sensory attributes that resonate with consumers.
Genetic and telomeric variability: Insights from a tropical avian hybrid zone
Authors: Vernasco Ben J. , Long Kira M. , Braun Michael J. , Brawn Jeffrey D. 
Published: August 2024

AbstractTelomere lengths and telomere dynamics can correlate with lifespan, behaviour and individual quality. Such relationships have spurred interest in understanding variation in telomere lengths and their dynamics within and between populations. Many studies have identified how environmental processes can influence telomere dynamics, but the role of genetic variation is much less well characterized. To provide a novel perspective on how telomeric variation relates to genetic variability, we longitudinally sampled individuals across a narrow hybrid zone (n = 127 samples), wherein two Manacus species characterized by contrasting genome‐wide heterozygosity interbreed. We measured individual (n = 66) and population (n = 3) differences in genome‐wide heterozygosity and, among hybrids, amount of genetic admixture using RADseq‐generated SNPs. We tested for population differences in telomere lengths and telomere dynamics. We then examined how telomere lengths and telomere dynamics covaried with genome‐wide heterozygosity within populations. Hybrid individuals exhibited longer telomeres, on average, than individuals sampled in the adjacent parental populations. No population differences in telomere dynamics were observed. Within the parental population characterized by relatively low heterozygosity, higher genome‐wide heterozygosity was associated with shorter telomeres and higher rates of telomere shortening—a pattern that was less apparent in the other populations. All of these relationships were independent of sex, despite the contrasting life histories of male and female manakins. Our study highlights how population comparisons can reveal interrelationships between genetic variation and telomeres, and how naturally occurring hybridization and genome‐wide heterozygosity can relate to telomere lengths and telomere dynamics.
The impact of financial inclusion on rural–urban households welfare inequality in Ghana: A decomposition analysis
Authors: Tawiah Thompson Ogajah , Sakyi Daniel , Ayibor Raphael Edem , Amanor Kofi 
Published: August 2024

AbstractThis article examined the impact of financial inclusion on rural–urban households' welfare inequality in Ghana using nationally representative survey data sourced from the seventh round of the Ghana Living Standard Survey. The article used a multidimensional financial exclusion index and the real per adult equivalent measures of total annual household consumption expenditure as measures of financial inclusion and welfare, respectively. The article employed the instrumental variable estimation technique to account for the issues of endogeneity and sample selectivity bias associated with measuring financial inclusion. The estimated results from recentered influenced function‐Ordinary Least Squares of the unconditional quantile regression and the Oaxaca‐Blinder techniques show significant rural–urban welfare gaps in favor of urban households at the mean and across the selected quantiles. The study also found that differences in financial inclusion between rural and urban households contribute significantly to the welfare gaps, while the economic returns to financial inclusion reduce the welfare gaps both at the mean and the selected quantiles. The study recommends that policies aimed at improving financial inclusion as well as strengthening financial institutions in rural areas be put in place to help reduce the rural–urban welfare inequality in Ghana.
Theorizing Sexuality Politics of Neoliberalism: A Queer Sociological Approach
Authors: Jung Minwoo 
Published: August 2024

ABSTRACTThis article provides a critical overview of neoliberalism scholarship from a queer sociological perspective. Despite mainstream neoliberalism scholarship neglecting sexuality as a system of intersecting power relations, sociologists of sexualities have explored how neoliberalism reshapes the state, market, society, and subjectivity concerning sex, intimacy, and sexual politics. Highlighting the intersection of the sociology of sexualities with transnational feminist and queer studies, as well as critical race studies, I advocate for a refined understanding of sexuality as integral to neoliberalism's operations with empire, colonialism, and racial capitalism. I suggest areas for future research to further develop this understanding, including the emphasis on the variegated nature of neoliberalism, its ambivalence and contradictions, and its promiscuous convergence with other political, social, and cultural formations. This article ultimately calls for a queer political economic analysis in the continued engagement with neoliberalism and its interactions with sexuality politics to understand new global challenges and social transformations, including shifting geopolitics, digital and platform economies, and climate and reproductive crises.
An examination of the development of a secondary mathematics preservice teacher's use of effective questioning
Authors: Nolan Edward C. 
Published: August 2024

AbstractThis case study explores how one secondary mathematics preservice teacher develops his use of questioning for instruction over the course of a year. The article explores how experiences in a secondary mathematics methods course and student teaching provide opportunities for the preservice teacher to use questioning to elicit, interpret, and respond to student thinking. Using classroom activities, plan‐teach‐reflect cycles of instruction, and recordings and transcripts of instructed lessons, the preservice teacher creates, revises, and reflects on his use of questioning over the year. The study shows that preservice teachers can improve their questioning to help elicit, interpret, and respond to student thinking.

Authors: Dauch Thilo F. , Diebel Bastian , Jester-Zürker Roland 
Published: August 2024

Abstract
The analysis and the design of effective cooling schemes is essential for the integrity of turbomachinery components. Therefore, an accurate prediction of temperatures in critical devices is a necessity. This also applies to electrical turbomachinery such as hydropower generators. Focus of the current paper is on the prediction of the heat and fluid flow at the polewindings of such a machine. Three different numerical setups enabling the computation of winding temperatures are presented and benchmarked to each other. One of the approaches is the Bi-Fo scaling methodology, which demonstrates to perform best in terms of accuracy and computational effort. Finally, the impact of unsteadiness and turbulence modeling on the accuracy of the prediction is presented. In contrast to previous studies, the local distribution of fluctuations and its impact on the thermal boundary layers at the windings is highlighted yielding new fundamental insights into the local heat transfer mechanisms in hydro generators.
Towards New Insights in Gas Turbine Aerothermodynamics With Wall-Modeled LES and Immersed Boundary Method
Authors: De Vanna Francesco , Benini Ernesto 
Published: August 2024

Abstract
This paper introduces a novel methodology for investigating and analyzing the aerothermal dynamics of high-loaded gas turbine vanes. The method combines an advanced wall-modeled Large Eddy Simulation technique with an immersed boundary method, allowing for treating complex geometries on Cartesian grids and accurately handling high Mach and Reynolds flows. Compared to other similar solutions available in the literature, the method’s significant strength is its high compatibility with high-order numerical schemes and explicit algorithms. This allows efficient computing on modern GPU-based architectures, enabling scale-resolved simulations within a reasonable time frame, mainly comparable to more standard unsteady Reynolds-Averaged Navier-Stokes simulations. The effectiveness and accuracy of the method are demonstrated through testing and validation in various canonical scenarios, typical of wall turbulence studies. Here, for the first time, its ability to replicate experimental data associated with a gas turbine nozzle in the transonic regime is verified, testing numerical results compatibility with a precursor and well-established experimental campaign.
