Published: February 2025

Range counting is a fundamental operation in spatial data applications. There is a growing demand to facilitate this operation over a data federation, where spatial data are separately held by multiple data providers (a.k.a., data silos). Most existing data federation schemes employ Secure Multiparty Computation (SMC) to protect privacy, but this approach is computationally expensive and leads to high latency. Consequently, private data federations are often impractical for typical database workloads.This challenge highlights the need for a private data federation scheme capable of providing fast and accurate query responses while maintaining strong privacy.
To address this issue, we propose U-DPAP, a utility-aware efficient privacy-preserving method. It is the first scheme to exclusively use differential privacy for privacy protection in spatial data federation, without employing SMC. Moreover, it combines approximate query processing to further enhance efficiency. Our experimental results indicate that a straightforward combination of the two techniques results in unacceptable impacts on data utility. Thus, we design two novel algorithms: one to make differential privacy practical by optimizing the privacy-utility trade-off, and another to address the efficiency-utility trade-off in approximate query processing. The grouping-based perturbation algorithm reduces noise by grouping similar data and applying noise to the groups. The representative data silos selection algorithm minimizes approximate error by selecting representative silos using the similarity between data silos. We rigorously prove the privacy guarantees of U-DPAP. Moreover, experimental results demonstrate that U-DPAP enhances data utility by an order of magnitude while maintaining high communication efficiency.

Deterministic concurrency control (DCC) guarantees that the same input transactions produce the same serializable result. It offers benefits in both distributed databases and blockchain systems. Dozens of DCC algorithms have emerged in the past decade. However, there is a lack of comprehensive evaluations for them.
To study the performance of existing DCC algorithms and discover further opportunities, we make the following contributions. First, we abstract five essential features from the existing DCC algorithms: generality, speculative mechanism, version strategy, batch strategy, and concurrency mode. Each distinct combination of these features corresponds to a specific algorithm. Second, we implement 13 DCC algorithms and conduct evaluations focused on their features by using 10 workloads, to conclude each feature’s strengths and weaknesses. Thirdly, based on our feature analysis, we discover opportunities for improvement in two existing DCC algorithms, resulting in performance boosts of up to 2.3x and 3.4x.

Abstract
Ovarian cancer accounts for more deaths than any other cancer of the female reproductive system. Patients who have ovarian tumors infiltrated with high frequencies of T cells are associated with a greater survival probability. However, therapies to revitalize tumor-associated T cells, such as PD-L1/PD-1 or CTLA4 blockade, are ineffective for the treatment of ovarian cancer. In this study, we demonstrate that for ovarian cancer, Toll-Like Receptor 5 (TLR5) signaling, for which the only known ligand is bacterial flagellin, governed failure of PD-L1 and CTLA4 blockade. Mechanistically, chronic TLR5 signaling on CD11c+ cells in vivo and in vitro impaired the differentiation of functional IL-12-producing XCR1+CD103+ conventional type 1 dendritic cells (cDC1), biasing CD11c+ precursor cells toward myeloid subsets expressing high levels of PD-L1. This culminated in impaired activation of CD8+ T cells, reducing CD8+ T-cell function and ability to persist within the ovarian tumor microenvironment. Expansion of cDC1s in situ using FLT3L in combination with PD-L1 blockade achieved significant survival benefit in TLR5 knockout mice bearing ovarian tumors, whereas no benefit was observed in the presence of TLR5 signaling. Thus, we have identified a host-intrinsic mechanism leading to the failure of PD-L1 blockade for ovarian cancer, demonstrating that chronic TLR5 signaling on CD11c+ cells is a barrier limiting the efficacy of checkpoint therapy.

This theoretically framed report outlines an iterative experiment in the deployment of worlding as a method and includes stories, data, results, and recommendations that may be of interest to scholars, artists, climate scientists, curators, documentarians, speculative designers, and land-use planners.
An AI-powered Interactive Platform for Visualizing Psychological States and Processes
Authors: Rakshit Abhishek , Gabora Liane 
Published: February 2025

Abstract
The Indra’s Net platform aims to enhance self-understanding, emotional regulation, and flourishing by providing a system for visually depicting psychological states (e.g., high arousal) and processes (e.g., repression). It uses a metaphor between properties of light and psychological processes that is cross-culturally universal and reflected in language (e.g., “ray of hope,” “brilliant idea”). A large language model assistant learns to associate user descriptions of psychological states and processes with the visual metaphor (e.g., reflecting on an idea is depicted as reiterated reflection of light) to render the states and processes more tangible and manageable.

Abstract
This paper situates the current iteration of artificial intelligence in a historical context to introduce the Technological Imaginary as a recent concept that can throw light upon why the technologies that we use have the form that they do. The Technological Imaginary is explored here in relation to the post-war development of AI in a summary of Accidental Machines to highlight the imaginary aspect of computer-based technological solutions to the creation of human intelligence. It concludes by suggesting how discussions of AI might benefit from recognizing the power of human agency in technological form and the visions for its future.
From Multimodal Sensorimotor Integration to Semantic Networks: A Phylogenetic Perspective on Speech and Language Evolution
Authors: Michon Maëva , Aboitiz Francisco 
Published: February 2025

Abstract
This integrative perspective article delves into the crucial role of the superior temporal sulcus (STS) and adjacent perisylvian regions in multimodal integration and semantic cognition. Drawing from a wide range of neuroscientific evidence, including studies on nonhuman primates and human brain evolution, the article highlights the significance of the STS in linking auditory and visual modalities, particularly in the establishment of associative links between auditory inputs and visual stimuli. Furthermore, it explores the expansion of the human temporal lobe and its implications for the amplification of multisensory regions, emphasizing the role of these regions in the development of word-related concepts and semantic networks. We propose a posteroanterior gradient organization in the human temporal lobe, from low-level sensorimotor integration in posterior regions to higher-order, transmodal semantic control in anterior portions, particularly in the anterior temporal lobe. Overall, this perspective provides a comprehensive overview of the functional and evolutionary aspects of the STS and adjacent regions in multimodal integration and semantic cognition, offering valuable insights for future research in this field.

Published: February 2025

Abstract
A central question of climate change impact assessments is identifying when the signal of change emerges from the noise of natural variability, though to date, this framework has been almost exclusively applied under warming conditions. In this work, we investigate the phenomenon of de-emergence, where temperatures rise beyond a given threshold and subsequently drop back below that threshold as forcing reverses. Large-scale carbon dioxide removal (CDR), also referred to as negative emissions, has been proposed to lower global average temperatures and to mitigate damage to the Earth system, though the regional effects of this have been understudied to date. Here, we analyze the results of eight Earth system models (ESMs) that participated in the CDR Model Intercomparison Project (CDRMIP). Decades after CO2 concentrations return to preindustrial levels following a gradual quadrupling, the only regions that most models agree to return to preindustrial temperatures are an area across northwestern Eurasia and a small area off the coast of West Antarctica. Around half of the models project de-emergence for areas of North America and East Asia. We investigate potential causes for these patterns and find that the land areas that cool more also exhibit enhanced latent heat flux, net carbon uptake, and precipitation, implying enhanced evapotranspiration. The region off West Antarctica appears to experience a cooling influence from changes to sea ice and meltwater. Both regions experience changes to cloud radiative effects that cause net cooling. The distribution of de-emergence patterns raises questions about the equity and fairness of overshoot scenarios.

Significance Statement
In this work, we seek to find out which regions of the globe are more likely to return to preindustrial conditions after a significant warming overshoot (a concept we call de-emergence), as well as why. Northwestern Eurasia and a small area off West Antarctica, and to a lesser extent parts of North America and East Asia, are the regions where temperatures are most likely to de-emerge in an idealized experiment. We identify changes to the hydrological and carbon cycles, as well as the cryosphere and clouds, as major drivers of these patterns. These findings are important for understanding both the regional effects and ethical implications of negative emissions after overshooting temperature goals.

Published: February 2025

Background Ulcerative colitis (UC) is a chronic condition characterised by inflammation of the large intestine, causing an impact on a patient’s psychological well-being. Earlier research has demonstrated the important role of locus of control (LOC) in facing the challenges brought out by many gastrointestinal system diseases. Purpose The aim of this research is to assess LOC in patients with mild-to-moderate UC as compared to non-UC individuals. This study also explored the impact of various demographic variables: age, gender, education level, type of family, working status, socio-economic status (SES), marital status and region of residence, on LOC among UC patients Methods A cross-sectional survey was conducted for a period of two months. The tool used was Multidimensional Health Locus of Control (MHLC). A chi-squared test was used to investigate the LOC among individuals with UC (100 patients) in comparison to a control group of non-UC (100) healthy individuals. The age group was between 30 and 50 years. Results In the UC group, 31% endorsed an internal LOC, while 40% attributed outcomes to chance, and 29% believed in powerful others. A chi-square test indicated a significant association between LOC and UC, χ²(2) = 38.1, P < .001. These findings suggest that individuals with UC are more likely to attribute outcomes to external factors, such as chance or powerful others, rather than their own actions. A positive effect of SES, region and working status on LOC was seen. Conclusion The observed tendency towards external LOC highlights the need for targeted interventions aimed at enhancing patients’ sense of agency and control over their health. Healthcare professionals can help people with these chronic conditions live better lives and achieve better results by enabling them to actively participate in their health.

Published: February 2025

Background Up to 10% of hospital deliveries may require neonatal resuscitation. After Neonatal Resuscitation Program (NRP) certification, pediatric residents are not formally trained in delivery room (DR) preparedness. Just-in-Time Training (JITT) is used to bolster skills for critical care practices and rarely used procedures. To address the expected decline in knowledge and skills after NRP training, we developed a formal JITT curriculum to familiarize residents with setting up and utilizing the radiant warmer (RW). Familiarity with its setup and use in resuscitation can bolster skills acquired through NRP certification. Objective To improve resident preparedness for DR setup by implementing a curriculum and to improve the setup of the RW by our residents by 10% from August 2020 to November 2023 using educational intervention. Design/Methods This study employed a one-group pretest-posttest design. Using NRP guidelines, we created a curriculum and checklist for DR preparedness. Baseline evaluation of residents included a questionnaire and demonstration of how to setup the RW, scored using a checklist. The questionnaire included statements regarding confidence and comfort in setting up the warmer. At the end of each rotation, residents were re-evaluated. Results Forty pediatric residents were evaluated and found to have a significant difference between pre- and posttest scores, with an average score improvement of 47.7. There was also an increase in self-reported confidence in comfort in DR setup ( P < .0001). Conclusion JITT in DR preparedness bolsters the skills gained through NRP certification and enhances the provision of high-quality neonatal resuscitation by pediatric residents.

Published: February 2025

Background Workplace bullying and organizational culture are two crucial factors that can significantly affect organizational performance. Understanding the interplay between these variables is imperative for creating conducive work environment and enhancing overall productivity. Additionally, demographic variables such as gender, age, designation, and work experience may also influence these dynamics within an organizational setting. Objective This study aims to investigate the influence of demographic variables on the relationship between workplace bullying, organizational culture, and organizational performance. Specifically, it examines three primary hypotheses: the impact of workplace bullying on organizational performance, the influence of organizational culture on organizational performance, and the moderating role of organizational culture in the relationship between workplace bullying and organizational performance. Methods Data were collected from academic staff members at 20 public universities in Malaysia, resulting in 626 responses. Structural Equation Modelling (SEM) was applied to test the primary hypotheses while the Partial Least Squares Multigroup Analysis (PLS-MGA) was employed through SmartPLS to explore the effect of demographic variables on the identified structural paths of the model. Results The findings indicate a significant negative impact of workplace bullying and a significant positive effect of organizational culture on organizational performance. Moreover, the analysis reveals notable variations across demographic subgroups. Additionally, the moderating effect of organizational culture demonstrates distinctions between subgroups based on varying levels of work experience, particularly between those with less than 10 years of experience and those with over 20 years. Conclusions This study provides valuable insights into the complex relationships among workplace bullying, organizational culture, and organizational performance within Malaysian public universities. The findings underscore the moderating influence of organizational culture and the contextual impact of demographic variables, shedding light on strategies for fostering a supportive work environment and enhancing overall organizational effectiveness.

Background Public health workers in the Errachidia province (Morocco) are confronted with a multitude of professional challenges that may precipitate burnout syndrome (BOS). Nevertheless, epidemiological studies in Morocco investigating this syndrome and its associated risk factors remain limited. Objective To identify burnout syndrome characteristics among health staff and investigate the main factors associated with the development of this syndrome. Methods An exhaustive cross-sectional study was implemented, with a target group of 750 health personnel. The Maslach Burnout Inventory test was used to assess burnout status. Binary Logistic regression was applied to estimate the risks associated with various socio-demographic, economic, and work-related environmental factors. The study was carried out in early 2019. Results Among the 503 health personnel employed in public establishments who completed the distributed and validated forms (response rate = 67.1%), a noteworthy prevalence of burnout (63.22%) was identified. This prevalence signifies a genuine state of emotional, physical, and mental exhaustion among medical and paramedical staff in the study area. The final adjusted logistic model revealed a significant association between burnout and the urban setting, female gender, and nursing profession. Furthermore, our findings indicated that, despite some autonomy, health workers experienced a lack of recognition from the hierarchy, and operated in understaffed structures with a predominant focus on medical rather than social tasks. Such conditions increase the burnout risk. Conclusions The status of burnout among healthcare professionals is determined by a complex interplay of risk and protective factors. Effective management strategies are essential to improve the well-being of this population.

Published: February 2025

Background The COVID-19 pandemic has posed substantial challenges to the occupational well-being of healthcare professionals. Uncertainty stress and social support are potentially substantial in influencing well-being during public health emergencies. Objective To assess the impact of uncertainty stress and social support on the occupational well-being of healthcare professionals during the COVID-19 pandemic and elucidate the pathways of interaction among these factors. Methods A cohort of 1028 healthcare professionals across 8 tertiary hospitals in Zhejiang Province were surveyed between May and June 2021 to evaluate their current occupational well-being, levels of uncertainty stress, and received social support. One-way analysis of variance, Pearson correlation analysis, and multiple linear regression models were utilised to analyse the factors influencing occupational well-being. Structural equation modelling (SEM) was employed to elucidate the pathways through which uncertainty stress and social support impact occupational well-being. Results The overall average score for the occupational well-being of healthcare professionals was 3.13 ± 1.02, indicating a moderate level. Pearson correlation analysis identified a significant negative correlation between uncertainty stress and occupational well-being ( r = −0.456, P < 0.01) and a positive correlation between social support and occupational well-being ( r = 0.219, P < 0.01). Multiple linear regression analysis highlighted that years of service, nature of employment, job position, leisure time, personality traits, self-rated health, uncertainty stress, subjective social support, and utilisation of social support were significant predictors of occupational well-being ( P < 0.05 for each). The SEM analysis demonstrated that uncertainty stress directly reduced occupational well-being ( β = −0.274, P < 0.05), whereas social support indirectly enhanced it by alleviating uncertainty stress ( β = 0.130, P < 0.05). Conclusion Uncertainty stress serves as a mediator in the relationship between social support and occupational well-being, with social support acting to buffer the effects of uncertainty stress and thereby enhance occupational well-being.
