Abstract
This study leverages machine learning to enhance the prediction of high-strength concrete (HSC) compressive strength, addressing the limitations of conventional methods, which are often tedious, less reliable, and time-consuming. Extreme Gradient Boosting (XGB) serves as the primary model, with hyperparameter optimization via metaheuristic algorithms such as Cuckoo Search (CSA), Water Strider (WS), Leopard Seal (LS), Harris Hawk (HH), Invasive Weed (IW), and Forest Optimization (FO). A total of 681 data sets were collected from existing literature. The models underwent tenfold cross-validation, with the LS-XGB model achieving an almost ideal performance in testing sets. Other models, including CSA-XGB, WS-XGB, HH-XGB, IW-XGB, and FO-XGB, also demonstrated strong performance, each with R2 > 0.96. For model explainability, Shapley's Additive Explanation (SHAP) analysis has been applied to the best-performing LS-XGB model. The analysis revealed that cement and superplasticizer (SP) are the most crucial features contributing to HSC development, with optimal ranges identified at 600–900 kg/m3 for cement and 8–10 kg/m3 for SP. The study demonstrates on how feature interactions contribute to concrete materials compressive strength, providing better and above all sustainable constructions. Furthermore, the LS-XGB model's optimal performance depicts the strongly nonlinear nature of HSC materials, validated through a set of derived graphs. Additionally, 30 concrete cubes were prepared for experimental validation, and the datasets demonstrated an accuracy of 92% showcasing the ability of models to make well informed decision.

Published: February 2025

Abstract
The electronics industry is expected to adopt more sustainable and circular product concepts and operations. Since the electronics value chains are complex, digital product passports (DPPs) that provide value chain transparency and traceability can be seen as one key enabler for shifting towards circular economy. Data carriers that are physical identifiers attached to products provide access to product data stored in the cloud and databases. Smart tags that combine item-level identification with condition monitoring are proposed to enable access also to dynamic lifecycle data of products to improve decision-making at end-of-life based on conditions that the product has been exposed to during its lifecycle. This dynamic information could be effectively used together with product data to decide on which circular economy strategy to adopt: reuse, remanufacture, repair, recycle etc. This paper analyses the data requirements of electronics value chain for DPPs, specifically focusing on which conditions to monitor with the help of smart tags. The data for this analysis was collected from ten developmental value chains aiming for sustainability and circularity with a questionnaire related to data needs, data access, data gaps, and data availability. The responses highlighted the need for data exchange and tools to monitor performance of components during storage and use. A printed visual humidity sensor is developed and analyzed as an experimental case study to help the value chains to dynamically monitor lifecycle conditions of products. This smart tag principal was functional with a visible colour change over time at different humidities between 33–72%RH, while not reacting at 0%RH. The relevance of different smart tag concepts is discussed and other important aspects, such as sustainability and durability of the smart tags, are included in the discussion.
Managing Organisational Sustainability and Corporate Social Responsibility: Perspectives for Sustainable Development
Authors: Silva D. Nayanee , Wehrmeyer Walter , Murphy Richard 
Published: February 2025

Abstract
Managing corporate sustainability involves consideration of the economic, environmental and social impacts of business activities on communities and society. Successful corporate sustainability strategy and sustainable operations must include an engaged and committed workforce. It has been seen that employees are increasingly seeking more purpose at work, with an awareness of environmental and social issues. Research has shown that employees engaged in corporate sustainability practices perceive their work as meaningful contributions to business performance. This empirical study explored sustainability performance in the tea industry, measured with a holistic sustainability framework and investigated the linkages between corporate social responsibility (CSR), employee engagement, and corporate contributions towards sustainability. The operations of participating organisations measured via a ‘7E’ model to benchmark sustainability performance, were compared with how employee engagement is influenced by CSR and wellbeing aspects. Data was collected from company sustainability surveys and surveys of 1146 employees in the tea industry. The results were analysed using a cluster model to assess employee attitudes to CSR and corporate sustainability practices towards sustainable development. The findings show that companies with strong company sustainability performance and developed social sustainability with CSR activities, have employees with higher participation at work and outreach engagement. Dimension reduction and the two-step cluster method was used to classify employee responses, showing the most engaged employees exhibited ‘shared values’ characteristics aligned with corporate engagement and social outreach. These results contribute to research on sustainability management from corporate and employee perspectives, with insights for sustainable development through CSR and sustainable business operations.

Abstract

Purpose
The objective of this study was to evaluate the functional and clinical outcome of submacular hemorrhage in age-related macular degeneration (ARMD) using pneumatic displacement with intravitreal expansile gas by 23Gauge pars plana vitrectomy with subretinal injection of recombinant tissue plasminogen activator (rtPA) 50 mg in 0.1 ml.

Patients and Methods
Retrospective interventional case series of 58 pseudophakic patients, who underwent surgical treatment with inclusion criteria: subretinal, subretinal pigment epithelium (subRPE), or combined central hemorrhage associated with ARMD, 23 Gauge pars plana vitrectomy using rtPA sulfur hexafluoride (SF6 20%). Medical records were reviewed for logMAR best corrected visual acuity (BCVA), clinical findings, complications, and medical history up to 6 months after surgery.

Results
Patients were classified with small hemorrhage up to 2 × 2 papillary diameter (PD) in 32 eyes, moderate hemorrhage (up to 4 × 4PD, to the arcades) in 19 eyes and massive hemorrhage (from 5 × 5PD hemorrhage through the arcades to the periphery) in 7 eyes. Improvement of average postoperative BCVA was the best in the group with moderate extension of hemorrhage, 1.58 logMAR preoperative to 1.14 logMAR postoperative. Regarding the association between the hemorrhage category and clinical outcome, there was a significant positive association between the hemorrhage size before the operation and the scored clinical outcome.

Conclusion
Anticoagulants are associated with massive hemorrhage and, at the same time, with better postoperative BCVA than massive hemorrhage without total anticoagulant treatment.
Decoding Chronic Jaw Pain: Key Nature of Temporomandibular Disorders in Slovak Patients
Authors: Kizek Peter , Pacutova Veronika , Schwartzova Vladimíra , Timkova Silvia 
Published: February 2025

Abstract

Background
Temporomandibular disorder (TMD) affects the jaw joint and muscles, causing pain, jaw movement issues and symptoms like clicking sounds. More common in women, TMD is linked to factors like stress, bruxism and posture. It often coexists with headaches and neck pain, with causes being a mix of physical and psychological factors. Therefore, we decided to examine Slovak patients with TMD to better understand their specific experiences.

Methods
Patients with TMD were recruited from the Department of Stomatology and Maxillofacial Surgery at University Hospital in Slovakia from 2017 to 2024, resulting in a sample of 380 patients. Inclusion criteria required adults aged 18–90 with TMD symptoms, such as jaw pain and movement difficulties, diagnosed by a maxillofacial surgeon. Patients completed paper-based questionnaires on background information; TMD characteristics and symptoms; and medical history, psychological factors and prior treatment.

Results
We confirm that TMD predominantly affects female patients (81.1%) and tends to be a chronic condition, with 58.6% of patients having experienced it for over 6 months. A significant proportion reported moderate to severe pain (42–26.4%) and nearly half (43.7%) experienced constant pain. Movement-triggered pain was common (67.8%), and most patients reported sound phenomena (96.9%) and difficulty opening the mouth (65.6%). Stress played a significant role, with 43.7% of patients experiencing a higher emotional burden and 32.4% reporting stress-related worsening of symptoms. Additionally, 46.3% of patients worked in sedentary environments, potentially contributing to their condition.

Conclusion
Most Slovak TMD patients experience multidimensional interplay of physical, psychological and social factors.

100 years of actual occupation as an overriding interest in English & Welsh land law: challenging the rationale and making the radical case for abolition
Authors: Bevan Chris 
Published: February 2025

Abstract
It is 100 years since the rights of those in ‘actual occupation’ joined the statute book as interests capable of binding transferees of land despite not appearing on the register. This paper seizes the opportunity to investigate and excavate the overlooked and under-examined historical origins of the actual occupation concept and to revisit the oft-touted rationales for the principle’s recognition. In so doing, the paper rejects the commonly-rehearsed justifications for the concept and makes the radical case for abolition of actual occupation.
Catch One and Lose Another? Executive Compensation Restriction and Corporate Social Responsibility in State-Owned Enterprises
Authors: Ning Peng , Lu Fangmei , Wan Guoguang , Jia Liangding 
Published: February 2025

AbstractThis study examines how the managerial interpretation of incentive arrangement affects corporate engagement in social areas, as reflected in corporate social performance, from two interrelated perspectives: the political influence view and the normative agency view. Building the theoretical framework on state-owned enterprise (SOE) executives' dual-career tracks perspective, we contend that economic factors (performance decline and relative pay gap) and political factors (socialist imprints and political career horizon) could divergently reshape the interpretation of incentive arrangement on corporate social performance. Using ‘Pay Ceiling Order’ as a quasi-natural experiment context, a secondary analysis, and a controlled experiment reveal that compensation restriction on top executives causes a decrease in corporate social performance. This relationship is weakened when there are stronger socialist imprints inherited by a focal firm and when the executives have a longer political prospect. In contrast, the relationship is strengthened when firms face severe performance declines and when the executives' compensation is relatively lower than peers. The findings show that compensation is an indispensable incentive joining with political and economic factors, enabling SOEs to engage in social areas. We discuss the implications of understanding top executive incentives with incentive arrangements and how the government purpose influences top executive responses to compensation incentive in ways that matter for long-term social value.

Subtle Bodies: Networks and Corporeality in Philipp Hainhofer’s Pomeranian Cabinet
Authors: Hutchinson Amelia 
Published: February 2025

Abstract
The merchant and art agent Philipp Hainhofer (1578–1647) is best known for his extraordinary art cabinets. Collaborating closely with neighbouring Augsburg artisans, Hainhofer worked to compile, collate, and market these visually and materially astounding collections to a range of elite patrons. His first commission, the Pomeranian Cabinet, was for Duke Philipp of Pomerania-Stettin in 1610, and took around seven years to complete. This article adopts a body-centred approach, arguing that in doing so, new light is shed on the ways period actors enacted their relationships with materials, objects, and other bodies. It uncovers the process through which the body of the art-lover was constructed, convening with those engaged in a shared material community through the lens of health and bodily entanglements. Hainhofer, as a merchant, diplomat, and secret agent, occupied a dubious position. Through the staging of the shared, art-loving body, he was able to create and sustain friendships, while simultaneously raising the status of the merchant through his material identification with these practices.
Incomplete Infrastructure: State-Building and the Early History of China’s Long-Distance Telephone Network, 1900–1937
Authors: Moazzin Ghassan 
Published: February 2025

Abstract
This article explores the hitherto understudied development of long-distance telephony in early 20th century China. It first explores the development of long-distance telephony before 1927 when it first appeared in China and was developed by foreign actors, the Qing government and various warlord regimes. The article then turns to the Nanjing Decade (1927-1937) and compares the efforts of the Nationalist government in building long-distance telephone infrastructure with those of the Guangdong provincial government and other regional regimes. The article uses the case of long-distance telephony to make two larger arguments about state-building in Republican China (1912-1949). First, it brings in telecommunications development as a major element of state-building of both central and regional regimes. Second, building on recent work by scholars of Chinese Republican-era state-building, it emphasizes the importance of studying state-building from the vantage point of both central and regional regimes in Republican China. Additionally, the article demonstrates the value of an infrastructural approach to the study of political competition and formation in China during the Republican era.
Export boom and re-primarisation: determining factors of a new export era in Latin American economic history
Authors: Ayuda María-Isabel , Belloc Ignacio , Pinilla Vicente 
Published: February 2025

Abstract
The objective of this article is to explain the characteristics of the agri-food exporting boom experienced by the Latin American countries between 1994 and 2019 and its determining factors. In so doing, we analyse the evolution of exports, their composition by product, the principal origins and destinations, the importance of regional trade agreements and the behaviour of export prices. Furthermore, a series of gravity models are estimated, using the agri-food exports of nineteen Latin American countries to their 186 main trading partners between 1994 and 2019. These models are estimated for total agri-food exports and for their breakdown into three product groups. Among the main determinants identified, our results suggest that external demand and the proliferation of regional trade agreements were the primary reasons for this export boom. Finally, we evaluate these results within the context of the region's economic history.
Auto-Tune as instrument: trap music's embrace of a repurposed technology
Authors: Duinker Ben 
Published: February 2025

Abstract
This article explores Auto-Tune's importance to the production, perception and reception of trap music, a sub-genre of hip hop. Central to this exploration is the observation that Auto-Tuned trap vocals are readily audible as such because the software's pitch correction function is applied unnaturally quickly to the vocal audio signal, a feature herein termed ‘zero-onset Auto-Tune’. First, I posit that although Auto-Tune is ostensibly a pitch-correction device, its impact on vocal timbre is not well documented or understood. Second, I argue that Auto-Tune's recent importance as a creative tool in trap recasts it as an instrument. Third, I suggest that understanding Auto-Tune's repurposing as an instrument begets its situation in a lineage of technologies repurposed, adapted and embraced by the hip-hop community, including the turntable, digital sampler, and analogue mixer. And fourth, I propose that this repurposing surfaces in Auto-Tune's ability to facilitate emotiveness in trap vocals.
Sociology of popular music in Czechoslovakia (1948–1989)
Authors: Blüml Jan 
Published: February 2025

Abstract
This article focuses on the history of the Czechoslovak sociology of popular music, which formed at the beginning of the 1960s. The article first examines the origins of thinking about ‘mass music genres’ in the Czech lands in the interwar period. It further discusses considerations of mass music genres and their audiences after World War II in light of the communist takeover in 1948, Stalinism of the 1950s and liberalisation of the 1960s. Finally, the article presents the situation after the occupation of Czechoslovakia by Warsaw Pact troops in 1968. Based on analysis of archival sources and original theoretical texts, hitherto unknown in the context of Anglophone scholarship, this article seeks to show how the specific political background of the Central European state behind the Iron Curtain determined the foundation, scholarly focus and social role of the sociology of popular music and how it differed from the situation in Western capitalist countries.
The roles of miR-101, miR-1183 and miR-1299 in acute rheumatic fever and rheumatic heart disease
Authors: Korkmaz Ece , Gürses Dolunay , Çetin Gökhan , Senol Hande 
Published: February 2025

Abstract

Introduction:
Acute rheumatic fever commonly causes carditis in children. It is critical to have biomarkers for diagnostic and prognostic purposes. We aimed to investigate the expressions of miR-101, miR-1183, and miR-1299 in children with acute rheumatic fever and rheumatic heart disease and determine their potential as diagnostic biomarkers.

Methods:
This cross-sectional study was conducted on 69 paediatric acute rheumatic fever patients and 27 gender and age-matched controls. The clinical findings were noted from medical records, echocardiography was repeated, and plasma miR-101, miR-1183, and miR-1299 expressions were studied using RT-PCR.

Results:
Out of 54 patients with carditis, 36 developed rheumatic heart disease with significant left-sided heart involvement. No significant demographic difference was present between rheumatic heart disease patients and controls (p > 0.05). miR-101 and miR-1183 expressions significantly reduced by 4.5-fold in acute rheumatic fever patients compared to controls (p : 0.029 and p : 0.024, respectively). Family history was found to be significantly associated with 9-fold reduced miR-1183 expression in acute rheumatic fever patients (p : 0.005). The expression of miR-1183 in acute rheumatic fever children with carditis in general and severe carditis was significantly reduced 4.5- and 9-fold, respectively (p : 0.024 and p : 0.007, respectively). In acute rheumatic fever cases with moderate-severe carditis and patients who did not develop rheumatic heart disease, miR-1183 expression significantly reduced 8.3-fold and 9-fold, respectively (p : 0.015 and p : 0.019, respectively). The ROC analysis revealed that miR-101 and miR-1183 were statistically significant for acute rheumatic fever diagnosis (AUC: 0.64 for both miRNAs).

Conclusions:
Significantly lower plasma expressions of miR-101 and miR-1183 in acute rheumatic fever patients, especially in cases with moderate-severe carditis, might indicate the potential use of these miRNAs as diagnostic biomarkers.
Reinforcement learning in women remitted from anorexia nervosa: Preliminary examination with a hybrid reinforcement learning/drift diffusion model
Authors: Wierenga Christina E. , Bischoff-Grethe Amanda , Brown Carina S. , Brown Gregory G. 
Published: February 2025

Abstract

Objective:
Altered reinforcement learning (RL) and decision-making have been implicated in the pathophysiology of anorexia nervosa. To determine whether deficits observed in symptomatic anorexia nervosa are also present in remission, we investigated RL in women remitted from anorexia nervosa (rAN).

Methods:
Participants performed a probabilistic associative learning task that involved learning from rewarding or punishing outcomes across consecutive sets of stimuli to examine generalization of learning to new stimuli over extended task exposure. We fit a hybrid RL and drift diffusion model of associative learning to model learning and decision-making processes in 24 rAN and 20 female community controls (cCN).

Results:
rAN showed better learning from negative outcomes than cCN and this was greater over extended task exposure (p < .001, ηp2 = .30). rAN demonstrated a reduction in accuracy of optimal choices (p = .007, ηp2 = .16) and rate of information extraction on reward trials from set 1 to set 2 (p = .012, ηp2 = .14), and a larger reduction of response threshold separation from set 1 to set 2 than cCN (p = .036, ηp2 = .10).

Conclusions:
rAN extracted less information from rewarding stimuli and their learning became increasingly sensitive to negative outcomes over learning trials. This suggests rAN shifted attention to learning from negative feedback while slowing down extraction of information from rewarding stimuli. Better learning from negative over positive feedback in rAN might reflect a marker of recovery.
