Analyzing the Impact of Tall Building Geometries on Wind Environment in a Hypothetical Urban Context: A Typological and Parametric Study
Authors: Wu Yihan , Li Weifeng , Zeng Ningyi , Bai Xiaoxia 
Published: November 2024

AbstractInfill development has become a popular strategy for revitalizing old urban districts. However, the construction of new high-rise buildings can cause nuisance issues that are of great concern to indigenous residents. Our study seeks to address three key research questions by examining the impacts of 34 high-rise building typologies within a hypothetical urban context: 1) To what spatial extent does the construction of new high-rise buildings significantly affect their surroundings? 2) How do different tall building typologies modify their surrounding buildings’ outdoor and indoor ventilation potentials? 3) What are the quantitative relations between building geometrical variables and wind performance indicators? The findings reveal that the correlation between building shape and wind behaviors is strongest within a radius of 0.7~1.3H of the target building. Moreover, the study observes that building width, building projected width, frontal area, and shape coefficient can substantially affect indoor and outdoor ventilation potentials of the surrounding spaces, but the influence of these parameters significantly varies depending on the incident wind direction. Certain building typologies can increase the outdoor ventilation potential of the neighborhood by 10–20%. Furthermore, the study employs an elastic net model to investigate the multivariate relations between building geometrical variables and wind performance indicators. The results indicate that the elastic net model outperforms ridge and lasso regression models in predicting wind performance indicators. These findings can enhance our understanding of how to design a tall building within an existing urban configuration.

Published: November 2024

AbstractPM2.5 is one of the main pollutants of air pollution. Long-term exposure to high concentrations of PM2.5 polluted environment can easily increase the risk of developing various diseases including cardiovascular disease and respiratory diseases. As the main place for people's leisure and entertainment, the exposure level and health risk of PM2.5 in urban commercial districts directly relate to people's health. Based on the principle of exposure assessment, this paper constructs a method for assessing the health risk of urban public space environment and carries out empirical research on the commercial district of Mianyang by using on-site measurement methods. On the basis of collecting PM2.5 concentration data, combined with the type of crowd activity and stay time, important public spaces in the commercial district are selected for health risk assessment and optimization strategies are proposed. Researches Indicate that the change of PM2.5 concentration in commercial areas is affected by traffic flow and wind direction; there is a high health risk in public spaces where crowds gather and stay for a long time. The research results have important practical significance for improving the public disease prevention ability and health management level in cities.

Authors: Zhang Baoqing , Rao Yubin , Guo Yunyi , Xiao Wangqiang 
Published: November 2024

AbstractIn order to reduce the adverse effects of noise generated by urban vehicles on residents, a super-structured phononic crystals sound isolation plate is designed to enhance the low-frequency noise reduction capability of the plate by utilizing the special acoustic properties of the super-structure. The phononic crystals plate is modeled and analyzed using the finite element method to study its band gap. The energy band and transmission loss patterns of phononic crystals are obtained, and the noise reduction capabilities of traditional sound isolators and phononic crystals plate are compared. Through experimentation, the noise reduction effect of the phononic crystal sound insulation plate was found to be remarkable. This provides theoretical support for the use of phononic crystals sound insulation devices in managing urban noise.
Investigating Urban Resilience Differences and Barriers to Regional Coordinated Development
Authors: Deng Weimin , Zhang Wenjun , Yan Li 
Published: November 2024

AbstractThe article evaluates and analyses urban resilience and constraining factors in 30 provinces in China derived from panel data from 2006–2021 using entropy weighting, Gini coefficient and handicap model. The study shows that the current level of resilience in most cities is relatively low, with an overall upward trend, and the spatial distribution shows a decreasing ‘high east, low west’ pattern, While the majority of the nation's low-resilient communities are found in the west and center, and high resilient towns are mainly found in the east. Concerning the decomposition of regional differences, the eastern region has the largest intra-regional difference and the smallest increase, the central region has a smaller difference and the largest increase, the northern difference shows a decreasing trend and the western difference is increasing year by year; in terms of inter-regional averages, the east-west difference is the largest and the north-central difference is the smallest. When analysing the level of barriers, the level of barriers to business resilience is decreased and the degree of barriers to infrastructural resilience is enhanced.; the number of fixed internet users, revenue from local budgets and local education expenditure emerge as important factors in increasing urban resilience, but the level of barriers varies across regions. Using the conclusions of this paper, the article proposes policy advice for enhancing urban resilience in terms of strengthening the connectivity of regional cities, optimising the allocation of resources in cities, and adhering to multi-system coordination of cities.
Homomorphisms from Functional Equations: The Goldie Equation, II
Authors: Bingham N. H. , Ostaszewski A. J. 
Published: November 2024

AbstractThis first of three sequels to Homomorphisms from Functional equations: The Goldie equation (Ostaszewski in Aequationes Math 90:427–448, 2016) by the second author—the second of the resulting quartet—starts from the Goldie functional equation arising in the general regular variation of our joint paper (Bingham et al. in J Math Anal Appl 483:123610, 2020). We extend the work there in two directions. First, we algebraicize the theory, by systematic use of certain groups—the Popa groups arising in earlier work by Popa, and their relatives the Javor groups . Secondly, we extend from the original context on the real line to multi-dimensional (or infinite-dimensional) settings.
Emotionale Belastung von Medizinstudierenden im Rahmen der universitären Lehre zu psychischen Erkrankungen
Authors: Besse Matthias , Belz Michael 
Published: November 2024

Zusammenfassung
Hintergrund
Zahlreiche Studien belegen eine hohe Ausprägung sowie Zunahme stressassoziierter Symptome und depressionsähnlicher Beschwerden bei Studierenden. Im Rahmen der Lehre zu psychischen Erkrankungen an unserer medizinischen Fakultät berichteten Studierende wiederholt emotional belastende Situationen und äußerten den Wunsch nach Unterstützungsangeboten. Ziel der vorliegenden Studie war die Objektivierung des Belastungslevels und des Bedarfs nach Unterstützungsangeboten.

Material und Methoden
Insgesamt 118 Studierende des 9. Semesters (WiSe 22/23) wurden mittels Fragebogen zu ihrer emotionalen Belastung befragt. Der Fragebogen wurde als Onlinebefragung in LimeSurvey (LimeSurvey GmbH, Hamburg, Deutschland) durchgeführt und enthielt insgesamt 18 als Statements formulierte sowie weitere Items. Zu den einzelnen Items konnten die Studierenden auf 11-stufigen numerischen Skalen mit Außenankern Ratings abgeben.

Ergebnisse
Die eigene Belastung im Vergleich zu anderen Modulen wurde als erhöht eingeschätzt – insbesondere für das Fach Psychiatrie (> 5 von 10). Am belastendsten wurde der Unterricht am Krankenbett, gefolgt von Seminaren und Vorlesungen eingeschätzt (alle Paarvergleiche p < 0,001). Inhalte zu Depression erzeugten überwiegend die stärkste Belastung. Etwa die Hälfte der Studierenden wünschte sich unterstützende Angebote; hiervon am häufigsten eine Sprechstunde (78,0 %) sowie feste Ansprechpartner (70,7 %).

Diskussion
Die emotionale Belastung von Studierenden im Rahmen der Lehre zu psychischen Erkrankungen ist insbesondere im Fach Psychiatrie sowie mit ansteigendem Patientenkontakt höher, Unterstützungsangebote werden gefordert. Lehrende sollten hierzu sensibilisiert werden und Angebote wie offene Sprechstunden oder die Benennung fester Ansprechpartner schaffen.
Moderne medikamentöse Schmerztherapie in der Gefäßmedizin – was der Gefäßchirurg dazu wissen sollte anhand einer einrichtungsspezifischen „Standard Operating Procedure“ (SOP)
Authors: Brinkers Michael , Pfau Giselher , Strang Maria Christof , Lodes Uwe , Barth Udo , Meyer Frank , Halloul Zuhir 
Published: November 2024

Zusammenfassung
Hintergrund
Bereits vor Jahren wurde von der interdisziplinär besetzten Arbeitsgruppe des Universitätsklinikums Magdeburg A. ö. R. eine „Standard Operating Procedure“ (SOP) zur postoperativen Schmerztherapie in der Allgemeinchirurgie veröffentlicht.

Ziel
Es wurde erweiternd eine Anpassung der „SOP – postoperative Schmerztherapie“ auf die Gefäßchirurgie erforderlich.

Methode
Narrative Kurzübersicht, basierend auf der „SOP – Schmerztherapie in der Gefäßchirurgie“ (als QR-Code im Anhang).

Ergebnisse (Eckpunkte)
Während die Inzidenzen der meisten Gefäßveränderungen aufgrund einer Erkrankung (z. B. rheumatoide Arthritis, Vaskulitiden) in der Bevölkerung im Promillebereich liegen, sind die Gefäßveränderungen aufgrund von „Zivilisationskrankheiten“ (Ulcus cruris, chronische Wunde) und zunehmendem Alter aufgrund gestiegener Lebenserwartung teils im zweistelligen Prozentbereich präsent und steigen in der Inzidenz weiter an. Ihre Behandlung liegt zunächst in der Therapie der Risikofaktoren, erst in höheren bzw. ausgeprägteren Stadien in einer operativen Therapie. Bei den weiteren ischämischen Gefäßveränderungen (Aneurysma, Carotisstenose, akuter Gefäßverschluss) stehen endovaskuläre oder offen-operative Verfahren im Vordergrund.

Schlussfolgerung
Different zu anderen Bereichen der Schmerztherapie sind viele Patienten mit Gefäßerkrankungen nicht zwingend mit Schmerzmitteln auf längere Zeit zu therapieren. Die Schmerztherapie beginnt grundsätzlich bei niedrigen Dosierungen. Schmerztherapie richtet sich nach der Schmerzqualität, der bisherigen Schmerzstärke, nicht nach dem Alter oder Geschlecht.
Job satisfaction declines before retirement in Germany
Authors: Henning Georg , Muniz-Terrera Graciela , Stenling Andreas , Hyde Martin 
Published: November 2024

AbstractJob satisfaction has been found to increase with age. However, we still have a very limited understanding of how job satisfaction changes as people approach retirement. This is important as the years before retirement present specific challenges for older workers. We employed a time-to-retirement approach to investigate (i) mean levels of change in job satisfaction in the decade before retirement, and (ii) social inequalities and interindividual differences in change in pre-retirement job satisfaction. Data were drawn from the German Socioeconomic Panel Study (n = 2595). Latent growth curve modeling revealed that job satisfaction declined slightly as people approached retirement, with steeper declines in the very last years before retirement. However, the mean-level decline was very small. Education, age, health, region, marital status, and historical time, but not gender or caregiving mattered for level and change in job satisfaction before retirement. The findings demonstrate the importance of taking a time-to-retirement approach when examining experiences of older workers.
Ruminant livestock and climate change: critical discourse moments in mainstream and farming sector news media
Authors: Simmonds Philippa , Maye Damian , Ingram Julie 
Published: November 2024

AbstractThere is ongoing contestation around greenhouse gas emissions from ruminant livestock and how society should respond. Media discourses play a key role in agenda setting for the general public and policymakers, and may contribute to polarisation. This paper examines how UK news media portrayed ruminant livestock’s impact on climate change between 2016 and 2021. The analysis addresses a gap in the literature by comparing discourses in national and farming sector newspapers using a qualitative approach. Four national and two farming sector news outlets were searched for articles published between 2016 and 2021. A corpus of 996 relevant articles was assembled, from which 154 were selected for in-depth examination using Critical Discourse Analysis. Four ‘Critical Discourse Moments’ (CDMs), each signifying a discursive shift in the debate, were identified over the 6-year studied period: 1) Low salience, diverging discourses, 2) We must eat far less meat, 3) Fighting the anti-meat agenda, and 4) Policy (in)action at COP26. There was a large increase in the number of published articles from January 2019 onward, partly associated with publication of the EAT/Lancet Commission report. CDM 2 (We must eat far less meat) occurred mainly in the national media, while CDM 3 (Fighting the anti-meat agenda) occurred mainly in the farming media. Our findings reveal both opinion polarisation and intergroup polarisation between national and farming sector media, and low engagement with food system power imbalances. Addressing polarisation will be important to enhance capacity for collective decision-making regarding methane emissions from ruminant livestock.
Bridging the gap: exploring consumer knowledge, perceptions, and willingness to pay for aquaponics products across the UK

Published: November 2024

Abstract
Aquaponics (a sub-field of integrated agri-aquacultural practices (IAAS)) has emerged as a novel approach to combat global food security, reduce soil erosion and nutrient loss, and mitigate agronomic greenhouse gas (GHG) emissions. However, little remains known of potential consumer markets. Despite recent research throughout Europe, Central America, Australia, and the Middle East, this work represents the first large-scale evaluation of UK consumer understanding, assessment, and willingness to pay (WTP) for aquaponic products. Following analysis of 588 survey responses, we identify environmental awareness and green consumption, recognition of common UK eco-labels and sector-specific certification schemes, and consumer perceptions of aquaponics compared to conventional, locally sourced, and organic food production. Initially, 44% of survey respondents were familiar with aquaponics, with familiarity positively influenced by age and level of education. After presenting a definition of aquaponics (detailing its use and commonly cited socio-environmental benefits), consumer perceptions were mixed, with respondents broadly favourable to the practice despite uncertainty. Over 43% of consumers were willing to pay an associated price premium for aquaponic produce (valued, on average, as a 23% price increase over conventional alternatives). This willingness to pay was statistically in line with the organic market premiums and independent of prior familiarity with aquaponics as a food production system. These findings suggest a sizable consumer market for aquaponic produce and public interest in its sustainability benefits. Tailored marketing strategies could position aquaponic produce competitively alongside organic and environmentally friendly alternatives (irrespective of certification/eco-labelling), ensuring the long-term economic viability of the emerging aquaponics industry.

Published: November 2024

AbstractThe objective of this research is to provide evidence that it is possible to obtain a prediction that better aligns with the future performance of a stock if a neural network model is trained with stock market analysis variables and qualitative variables. As a case study, thirty-three companies’ representative of the S&P 500 are selected, and a multilayer perceptron artificial neural network is built and trained with input parameter indicators of fundamental analysis, technical analysis, and market sentiment. By incorporating the latter as an additional variable, the model's accuracy increases by 1.5% for 66% of the companies analyzed. The results confirm the crucial role played by the selection of the neural network model and its variables depending on the type of company to be analyzed. The main contributions of this research are the identification of the best variables combination to train a neural network model depending on the market sector to be analyzed, likewise it is demonstrated that, by using market sentiment, it is possible obtain a high accuracy or increase the accuracy to an existing model.
Effects of School-led Greenspace Interventions on Mental, Physical and Social Wellbeing in Children and Adolescents: A Systematic Review
Authors: Ly Vi , Vella‐Brodrick Dianne A. 
Published: November 2024

AbstractPromoting children’s and adolescents’ mental, physical, and social wellbeing is highly important to help them learn, create social connections, and stay healthy. Nature has the potential to restore cognition, reduce stress and mental fatigue, and improve wellbeing, all factors that are conducive to learning. There is growing interest in understanding the effects of nature on the wellbeing of children and adolescents, particularly in the school context. This paper presents a PRISMA-guided systematic review of the literature examining the effects of school-led nature interventions on the mental, physical, and social wellbeing of school children and adolescents aged 5 to 19 years. Examples of school-led nature interventions include outdoor learning, walks in nature and green schoolyards. Experimental and quasi-experimental studies employing quantitative measures were selected, yielding 19 studies from 17 papers. Included studies were rated as being of high (n = 6) and moderate quality (n = 13). The results provide some evidence that nature exposure in the school context can improve the wellbeing of children and adolescents, particularly their positive affect, physical activity, and social relationships/interactions. The wellbeing effects of school-led nature interventions were also examined according to age and gender, with results indicating a gender effect, but inconclusive findings for age. Findings from this review support the integration of nature in schools to enhance the mental, physical and social wellbeing of children and adolescents.
Misattribution stigma and contagion: How did the art auction market react to Australian “Black art scandals”?
Authors: Coslor Erica , Fry Tim R. L. 
Published: November 2024

AbstractIn 1999, two major stories hit the media concerning the authenticity of artworks by two of Australia’s leading Indigenous artists. The incidents were quickly tagged as ‘Black art scandals’, with the artists disavowing production of the artworks in question. We theorize the market impacts using the lens of stigma, given that, in the art market, uncovering fakes and forgeries may create a panic among buyers of an artist. Our proposed mechanism is that negative media attention about works misattributed to an artist stigmatizes the artist’s name and their artworks. We also note the potential stigma transfer to other artists in a style or genre (category-level contagion). Our results show a decline in the clearance rate and some weak evidence of a fall in the value of sales for auctions occurring after the news stories broke. We suggest stigma as a lens for future work in cultural economics.
Morphology and Luminescence Properties of Transition Metal Doped Zinc Selenide Crystals

Published: November 2024

AbstractZinc selenide is an excellent matrix material to dope with rare-earth and transition metal to achieve mid-infrared luminescence to develop high power lasers. The luminescence, morphology and refractive index is significantly affected by the doping and defects generated due to size and valency of dopants, concentration, growth process and convection during the growth. The aim of the study is to investigate effect of point and line defects generated due to low doping of iron and chromium on the emission and morphology of the zinc selenide. Luminescence and morphological properties of large iron and chromium doped zinc selenide single crystals were studied to evaluate the effect of extremely low residual impurities and defects associated with the doping process. The emission properties following both short wavelength (i.e., ultraviolet; 350–370 nm) excitation and longer wavelength (i.e., near infrared; 850–870 nm) excitation were characterized. Luminescence emission bands were identified in both doped crystals. In addition to the primary emission bands, satellite peaks and intra-center transitions were also observed. Due to local population defects associated with the residual impurities (ppm to ppb) in the Fe-ZnSe and Cr-ZnSe crystals, peak emission wavelengths were observed to shift. The emission bands were found to decrease in intensity due to recombination of residual impurity co-dopants and complex defects generated during growth and fabrication. Cryogenic temperature analyses revealed a very clean emission band due to freezing of some of the point and line defects. An emission band observed at 980 nm for both crystals at room temperature as well as cryogenic temperatures indicates a vibronic peak in ZnSe. The scanning electron microscopy (SEM) images of the local morphology support the conclusion that small crystallites in doped crystals are also present.
