Petroleum sludge formation and its treatment methodologies: a review
Authors: Hasan Abdulraheim M. A. , Kamal Rasha S. , Farag Reem K. , Abdel-raouf Manar E.
Published: January 2024

Different petroleum operations produce huge amount of oil sludge annually. For instance, US EPA estimates the annual sludge production of each US refinery of 30,000 tons, while the average oily sludge produced from petrochemical industries in China is estimated about 3 million tons per year. In the last year, our center could recover about 30,206 barrels of raw oil from 32,786 barrels of tank bottom sludge (TBS) for different petroleum companies. This sludge causes huge economic losses besides its negative environmental impacts. The accumulation of sludge in the tanks results in reducing the tanks’ capacity for storing liquid crude, accelerating the corrosion of the tanks, delay in the production schedule, and disturbing the whole production operation. There are diverse treatment methodologies such as solvent treatment, addition of certain chemicals, and centrifuging. Of course, the environmental regulations and the overall cost limitations are very important in deciding the preferred applicable method(s). Although several works handled the problem of sludge deposition and treatment from different aspects, we intend to introduce a different work. First, composition, formation, types, and properties of TBS were reviewed. Then, environmental and economic problems caused by TBS were revised. At last, different methodologies applied for treatment of oily TBS to recover oil and safe disposal of hazardous remains were investigated focusing on the most straightforward and environmentally friendly protocols. It is expected that this review attracts the experts in petroleum chemistry, and other relevant fields and provides a comprehensive understanding of current sludge control and treatment research.

Published: January 2024

Star trackers are crucial for satellite orientation. Improving their efficiency via reconfigurable COTS HW accommodates NewSpace missions. The current work considers SoC FPGAs to leverage both increased reprogramming and high-performance capabilities. Based on a custom sensor+FPGA system, we develop and optimize the algorithmic chain of star tracking by focusing on the acceleration of the image processing parts. We combine multiple circuit design techniques, such as low-level pipelining, word-length optimization, HW/SW co-processing, and parametric HLS+HDL coding, to fine-tune our implementation on Zynq-7020 FPGA when using real and synthetic input data. Overall, with 4-MPixel images, we achieve more than 24 FPS throughput by accelerating >95% of the computation by 8.9$$\times$$

Post-traumatic Embitterment Disorder in UK Authorised Firearms Officers Following Post-incident Procedures: A Cross-Sectional Web Survey
Authors: Brennan Chloe , Cole Jon
Published: January 2024

In the United Kingdom, authorised firearms officers (AFOs) respond to the most serious threats, and in situations where a weapon is discharged may be subject to a post-incident investigation. The investigation may feel unjust and lead to post-traumatic embitterment disorder (PTED), however, there is a lack of research on PTED in this group. The current study estimated the prevalence, predictors, and outcomes of PTED in 40 UK AFOs with experience of a post-incident procedure following a firearms-related incident. An online cross-sectional survey was hosted on Qualtrics, and participants were recruited via a gatekeeper at one UK police force. PTED was assessed using the PTED self-rating scale. Potential predictors and outcomes were measured using surveys of personal and general belief in a just world (BJW), including belief in distributive justice (i.e., fair outcomes) and procedural justice (i.e., fair processes), anger, and social desirability. Participants reported whether they had post-traumatic stress disorder (PTSD) or depression, and whether they experienced the post incident investigation as more problematic than the firearms incident. Results showed 15% of participants displayed clinically relevant levels of PTED. Having a possible post-traumatic stress disorder and/or depression diagnosis, feeling as though the post-incident procedure and subsequent treatment were more problematic than the incident itself, and a lack of belief in personal distributive justice, increased the risk of experiencing PTED and PTED predicted increased feelings of anger. Measures are needed to ensure the post-incident procedure delivers fair outcomes and that AFOs are given the right targeted support throughout the process.
Chronic Lymphocytic Leukemia: Time-Limited Therapy in the First-Line Setting and Role of Minimal Residual Disease
Authors: Stumpf Janina , Al-Sawaf Othman
Published: January 2024

Purpose of Review

In this review, we provide an overview of different time-limited combination therapies of chronic lymphocytic leukemia (CLL) and summarize the data of pivotal clinical studies. Furthermore, we discuss the relevance of MRD in clinical trials and summarize the challenges that arise in routine clinical care. Finally, we provide an outlook on studies and datasets needed to optimize the use of time-limited treatment strategies and MRD assessments in modern CLL management.

Recent Findings

In recent years, first-line treatment of CLL has undergone a considerable transformation, with targeted substances having largely replaced chemoimmunotherapy (CIT) as a time-limited strategy in the frontline setting. BTK inhibitors were the first class of targeted agents introduced in CLL, which achieved longer progression-free survival (PFS) and in some cases also overall survival (OS) than CIT. However, this required an indefinite drug intake until disease progression, while CIT is generally administered over the course of few months. In contrast to BTK inhibitors, BCL2 inhibitors, another class of targeted agents, can achieve high rates of undetectable minimal residual disease (uMRD) levels and induce deep molecular remissions with the potential to stop treatment while maintaining remissions.

Combinations of BCL2 inhibitors with CD20 antibodies or with BTK inhibitors have been explored to establish time-limited treatment strategies with targeted agents. In this context, one of the strongest predictors of long-term outcomes is MRD status at the end of treatment, which has been shown to correlate closely with PFS and OS in most cases.

Published: January 2024

Background

Cellular senescence is a state characterized by cell-cycle arrest and apoptotic resistance. Senescence in cancer may be induced by oncogenes or therapy. While cellular senescence might play an important role in protection against cancer development, elevated and uncontrolled senescent cells accumulation may promote carcinogenesis by secreting a collection of pro-inflammatory factors, collectively termed the senescence-associated secretory phenotype (SASP).

Material and methods

We determined the gene expression at mRNA level of selected cellular senescence markers (p16 and LMNB1) and SASP factors (IL-6, IL-1b, CXCL-1 and TNF-α) in 72 cancerous tissues and 64 normal tissues obtained from patients with head and neck squamous cell carcinoma (HNSCC) and correlated this data with patients’ clinical follow-up.

Results

Our results indicate higher levels of selected SASP factors in cancerous compared to normal tissues. We presented the relationship between SASP factors expression at the transcript level and the progression of the disease. Moreover, we proposed CXCL1 as a candidate biomarker differentiating normal tissues from cancerous ones and IL1b expression as a molecular factor related to increased TNM stage.

Conclusion

Our primary study indicates that SASP expression may be associated with some clinicopathological features. However, a more detailed study is needed to present specific role of senescence-related mechanism and SASPs especially in tumor therapy response and in relation to the patient’s immune system condition.
Agroecological-based modeling of meteorological drought at 12-month time scale in the Western Cape Province of South Africa
Authors: Ngwenya Mthulisi , Gidey Eskinder , Simatele Mulala Danny
Published: January 2024

To mitigate the effects of drought in water-stressed agro-ecological zones (AEZs), it is crucial to implement efficient monitoring of drought characteristics and establish proactive water-use strategies. The Western Cape (WC) province is being confronted with an escalating threat of diminished water availability due to unsustainable human activities. The objective of this study was to assess the spatio-temporal characteristics of meteorological drought within a 12-month timescale in the WC province of South Africa spanning from 1980 to 2020. The University of East Anglia's Climate Research Unit provided precipitation datasets from fifteen stations across the six AEZs of the WC province. These datasets were processed using the Standardized Precipitation Index (SPI). The Mann–Kendall (M–K) test was used to analyze the precipitation trend and SPI values at a significance level of p < 0.05. The results indicated substantial negative trends in annual precipitation across all AEZs. An examination of seasonal precipitation patterns revealed a rise in summer precipitation in subtropical cool-arid regions and subtropical warm semi-arid regions, with increases of 0.4 and 0.2 mm/year, respectively. Conversely, the overall annual precipitation trend fell by -1.0 mm/year in both AEZs. The SPI values consistently fell within the range of -2 to 0 in the subtropical warm-arid, subtropical cool-arid, and subtropical cool-arid zones. Conversely, the SPI values were consistently positive in the subtropical warm-arid, subtropical cool-humid, and subtropical warm-humid zones. This finding suggests that there will be persistent drought conditions that will affect agricultural production, surface flows in rivers, and groundwater levels across the WC province.

Published: January 2024

This paper utilizes fractional integration and cointegration techniques to investigate the stochastic properties of the bilateral linkages between the Consumer Sentiment Index (CSI) of eight developed economies, Australia, Canada, France, Germany, Italy, Japan, the UK and the US and five emerging economies comprising Brazil, Russia, India, China and South Africa, for the time period from 15th January 2010 to 15th July 2019. The univariate results support fractional integration with mean reverting behaviour, with many of the series displaying orders of integration in the interval (0, 1), which connotes that shocks to consumer sentiment have significant long-lasting though reverting effects. From the covariate results and testing for cointegration, we found evidence of cointegration for Australia versus Italy, and France versus Italy. For the BRICS, the only evidence of fractional cointegration is found between Russia and India. Some policy implications of the results obtained are also mentioned at the end of the article.
Insights into the oxidation resistance mechanism and tribological behaviors of multilayered TiSiN/CrVxN hard coatings

Published: January 2024

In the last decades, vanadium alloyed coatings have been introduced as potential candidates for self-lubrication due to their perfect tribological properties. In this work, the influence of V incorporation on the wear performance and oxidation resistance of TiSiN/CrN film coatings deposited by direct current (DC) reactive magnetron sputtering is investigated. The results show that vanadium incorporation significantly decreases the oxidation resistance of the coatings. In general, two layers are formed during the oxidation process: i) Ti(V)O2 on top, followed by a protective layer, which is subdivided into two layers, Cr2O3 and Si-O. ii) The diffusion of V controls the oxidation of V-containing coatings. The addition of vanadium improves the wear resistance of coatings, and the wear rate decreases with increasing V content in the coatings; however, the friction coefficient is independent of the chemical composition of the coatings. The wear of the V-containing coatings is driven by polishing wear.
Rapid and portable mid-infrared analysis of wet sediment samples by a novel “filter-press” attenuated total reflectance method
Authors: Janik Leslie J. , Simpson Stuart L. , Farrell Mark , Mosley Luke M.
Published: January 2024

Mid-infrared (MIR) analysis of wet sediments or soils usually requires freezing and drying, adding considerable analysis time and cost, and promoting changes in chemical properties. A novel attenuated total reflectance (ATR) mid-infrared (MIR) method was developed to enable analysis of non-processed, aqueous sediments. Wet sediment samples from the Coorong Lagoon, South Australia, were subjected to laboratory analysis for physical and chemical properties, our new filter-press ATR method, and conventional ATR and diffuse reflectance (DRIFT) analysis of dried samples. For ATR on wet sediments, samples were pressed onto the ATR crystal with a filter-paper backing and scanned. The spectra were analyzed by principal components analysis (PCA) and partial least squares regression (PLSR) to develop multivariate models for total organic carbon (TOC). ATR spectra of as-received wet sediments were poor due to water absorption features, but filter-pressing reduced these and greatly enhanced the solids spectral component. The filter-pressed PLSR cross-validation for TOC resulted in an R2 = 0.89 and RMSECV = 0.78%. Prediction accuracies were similar to freeze-dried ATR samples and far more accurate than testing wet samples without filter-pressing. Our findings confirmed the filter-press ATR method as proof-of-concept and showed that it has the potential to remove one of the major barriers to in-field application of MIR techniques, the high and variable amounts of moisture levels commonly present in many environmental samples. Extension of the filter-press ATR method to a wider range of analytes may enable it to rapidly acquire moist or wet sediment and soil property data while in the field.

Published: January 2024

Vegetation growth and the ecological environment affect each other. Understanding vegetation growth trend and their spatial pattern evolution is of great significance for ecological environment assessment and protection. The spatial trend and pattern evolution of different vegetation growth in the ecological area are included in vegetation planning, which can be used as a reference for vegetation planning and development. Based on Landsat remote sensing data, the spatial evolution trend and dynamic evolution of vegetation patterns at different levels in the Engebei Ecological Demonstration Zone from 2000 to 2021 were revealed, and the degree of ecological vulnerability was determined. The results show that: during the growing season from 2000 to 2021, the vegetation growth of the study area showed an overall improvement trend (about 63.44%), and the vegetation growth trends was mainly not significant change (about 97.12%). The improvement of vegetation growth in the southern desert region was higher than that in the northern arid steppe region. In the future, the main growth types were non-significant improvement of sustainability, non-significant improvement of anti-sustainability, non-significant degradation of anti-sustainability, and non-significant degradation, accounting for 38.84%, 23.81%, 17.30%, and 17.16%, respectively. The spatial distribution of vegetation of different grades mainly showed aggregation patterns, and the spatial distribution evolvement was more and more uniform, the distribution range was gradually expanded, and the orientation was gradually weakened. The numerical clustering degree of ecological vulnerability of vegetation was constantly declining. The results can provide a scientific basis for vegetation planning in the Engebei ecological demonstration area.
Metaphysical indeterminacy in Everettian quantum mechanics
Authors: Glick David , Le Bihan Baptiste
Published: January 2024

The question of whether Everettian quantum mechanics (EQM) justifies the existence of metaphysical indeterminacy has recently come to the fore. Metaphysical indeterminacy has been argued to emerge from three sources: coherent superpositions, the indefinite number of branches in the quantum multiverse and the nature of these branches. This paper reviews the evidence and concludes that those arguments don’t rely on EQM alone and rest on metaphysical auxiliary assumptions that transcend the physics of EQM. We show how EQM can be ontologically interpreted without positing metaphysical indeterminacy by adopting a deflationary attitude towards branches. Two ways of developing the deflationary view are then proposed: one where branches are eliminated, and another where they are reduced to the universal quantum state.

Published: January 2024

Background

Flywheel resistance training has become more integrated within resistance training programs in a variety of sports due to the neuromuscular, strength, and task-specific enhancements reported with this training.

Objective

This paper aimed to present the consensus reached by internationally recognized experts during a meeting on current definitions and guidelines for the implementation of flywheel resistance training technology in sports.

Methods

Nineteen experts from different countries took part in the consensus process; 16 of them were present at the consensus meeting (18 May 2023) while three submitted their recommendations by e-mail. Prior to the meeting, evidence summaries were developed relating to areas of priority. This paper discusses the available evidence and consensus process from which recommendations were made regarding the appropriate use of flywheel resistance training technology in sports. The process to gain consensus had five steps: (1) performing a systematic review of systematic reviews, (2) updating the most recent umbrella review published on this topic, (3) first round discussion among a sample of the research group included in this consensus statement, (4) selection of research group members—process of the consensus meeting and formulation of the recommendations, and (5) the consensus process. The systematic analysis of the literature was performed to select the most up-to-date review papers available on the topic, which resulted in nine articles; their methodological quality was assessed according to AMSTAR 2 (Assessing the Methodological Quality of Systematic Review 2) and GRADE (Grading Recommendations Assessment Development and Evaluation). Statements and recommendations scoring 7–9 were considered appropriate.

Results

The recommendations were based on the evidence summary and researchers’ expertise; the consensus statement included three statements and seven recommendations for the use of flywheel resistance training technology. These statements and recommendations were anonymously voted on and qualitatively analyzed. The three statements reported a score ranging from 8.1 to 8.8, and therefore, all statements included in this consensus were considered appropriate. The recommendations (1–7) had a score ranging from 7.7 to 8.6, and therefore, all recommendations were considered appropriate.

Conclusions

Because of the consensus achieved among the experts in this project, it is suggested that practitioners and researchers should adopt the guidelines reported in this consensus statement regarding the use of flywheel resistance technology in sports.
Tracking Regulatory Mechanism of Trace Fe on Graphene Electromagnetic Wave Absorption
Authors: Zhang Kaili , Liu Yuhao , Liu Yanan , Yan Yuefeng , Ma Guansheng , Zhong Bo , Che Renchao , Huang Xiaoxiao
Published: January 2024

Polarization and conductance losses are the fundamental dielectric attenuation mechanisms for graphene-based absorbers, but it is not fully understood in revealing the loss mechanism of affect graphene itself. For the first time, the reduced graphene oxide (RGO) based absorbers are developed with regulatory absorption properties and the absorption mechanism of RGO is mainly originated from the carrier injection behavior of trace metal Fe nanosheets on graphene. Accordingly, the minimum reflection loss (RLmin) of Fe/RGO-2 composite reaches − 53.38 dB (2.45 mm), and the effective absorption bandwidth achieves 7.52 GHz (2.62 mm) with lower filling loading of 2 wt%. Using off-axis electron hologram testing combined with simulation calculation and carrier transport property experiments, we demonstrate here the carrier injection behavior from Fe to graphene at the interface and the induced charge accumulation and rearrangement, resulting in the increased interfacial and dipole polarization and the conductance loss. This work has confirmed that regulating the dielectric property of graphene itself by adding trace metals can not only ensure good impedance matching, but also fully exploit the dielectric loss ability of graphene at low filler content, which opens up an efficient way for designing lightweight absorbers and may be extended to other types materials.
Upregulation of LmHxt1 gene is associated with reduced virulence of Leptosphaeria maculans on Brassica napus
Authors: Stehlík Daniel , Trdá Lucie , Leontovyčová Hana , Kalachova Tetiana , Burketová Lenka
Published: January 2024

Leptosphaeria maculans is a fungal pathogen that causes heavy losses of Brassica napus crops. To develop novel means of plant protection it is necessary to understand the virulence mechanisms of pathogens. In this study we investigated a T-DNA insertion mutant of L. maculans that exhibited a hypovirulent phenotype (pHxt1ins). The mutant contains a single T-DNA insertion that affects expression of a single gene identified as a transmembrane hexose transporter (LmHxt1). This gene exhibited enhanced expression in the pHxt1ins mutant during in vitro cultivation. The excess of glucose in the cultivation medium lowered expression of LmHxt1 in the mutant line, suggesting that the gene might function as a sugar sensor. Lack of virulence of the pHxt1ins mutant in planta was observed using fluorescence microscopy in GFP labeled lines ruling out asymptomatic growth and showing inability to successfully colonize the apoplastic space of B. napus. On the other hand, in vitro growth did not differ between pHxt1ins and control lines. Interestingly, the mutant showed altered mycelium morphology and a change in conidial germination. Overall, our results suggest that the LmHxt1 gene is a novel important virulence factor for L. maculans. We also propose pHxt1ins mutant as a tool to study the role of sugar transporters in fungal metabolism and pathogenesis.

Authors: Hides Julie A. , Leung Felix , Franettovich Smith Melinda M. , Anning Luke , Blanch Peter , Mendis M. Dilani
Published: January 2024

Purpose

Examine for injury risk factors and establish clinical cut-off values related to size and function of trunk muscles.

Methods

A prospective study of 28 professional Rugby League players was conducted. Cross-sectional areas (CSAs) of the multifidus (MF), quadratus lumborum (QL) and ability to contract the abdominal and MF muscles were measured from pre-season ultrasound images. Playing season injuries resulting in games missed were recorded by club personnel. Logistic regression models were used to determine the adjusted odds ratios for trunk muscle measures as risk factors for playing season injuries.

Results

The adjusted odds ratio (OR) values indicated that if a player had a small MF muscle (< 9.98 cm2 at L5; P = 0.032) or a small QL (< 10.8 cm2; P = 0.045), their odds of more games missed due to season injuries was increased (OR MF = 9.4; 95% CI = 1.21–72.9; OR QL = 7.3; 95% CI = 1.1–51.6). For players with increased contraction of the MF (contraction > 7.2%; P = 0.028) and abdominal muscles (> 49.9%; P = 0.08), the odds of sustaining a concussion were increased (OR MF 14.5; 95% CI 1.3–159; OR transversus abdominis 6.2; 95% CI = 0.8–48.6).

Conclusion

As size and ability to contract trunk muscles are modifiable factors, further intervention studies targeting motor control of these muscles may be warranted.
Proteomic Biomarkers of Intrahepatic Cholestasis of Pregnancy
Authors: Zeng Weijian , Hou Yanyan , Gu Wei , Chen Zheng
Published: January 2024

Intrahepatic cholestasis of pregnancy (ICP) is a pregnancy-specific liver disease, which can lead to adverse fetal outcomes, including preterm labor and intrauterine death. The pathogenesis of ICP is still unclear. We hypothesized that pathological index leads to abnormal placenta changes in ICP. Investigation of these differences in protein expression in parallel profiling is essential to understand the comprehensive pathophysiological mechanism underlying ICP. The present study screened differentially expressed proteins (DEPs) as novel diagnostic markers for ICP. Proteomic profiles of placental tissues from 32 ICP patients and 24 healthy volunteers (controls) were analyzed. Our founding was valid by following western blotting and immunohistochemistry staining, respectively. The association of the key protein expression with clinicopathological features of ICP was further analyzed. A total of 178 DEPs were identified between the ICP and control groups. Functional enrichment analysis showed these proteins were significantly enriched in the PPAR singling pathway by KEGG and PPARα/RXRα activation by IPA. Apolipoprotein A2 (APOA2) was the only upregulated protein, which uniquely identified in ICP groups and related to both pathways. Validation of western blotting and immunohistochemical staining analysis showed significantly higher APOA2 expression in the ICP group than in the control group. Furthermore, the expression of APOA2 is associated with clinicopathological features in ICP groups. Receiver operating characteristic (ROC) curve analyses showed that the AUC of APOA2 was 0.8984 (95% confidence interval (CI): 0.772–1.000). This study has identified up-regulated APOA2 associated with PPAR singling pathway and PPARα/RXRα activation in ICP. Thus, APOA2 may be involved in ICP pathogenesis, serving as a novel biomarker for its diagnosis.
Improving the mental health of farmers: what types of remote support are acceptable, feasible, and improve outcomes? A feasibility RCT
Authors: Lamont Kate , van Woerden Hugo C. , King Emma , Wendelboe-Nelson Charlotte , Humphry Roger W. , Stark Cameron , Williams Chris , Maxwell Margaret
Published: January 2024

Background

The farming community have high rates of poor mental health, and are relatively ‘hard to reach’ with mental health services. The aim of this study was therefore to undertake a feasibility RCT, based on two mental health interventions. These were (1) CBT based ‘Living Life to the Full for Farming Communities’ (LLTTF-F; www.llttf.com), and (2) a holistic social and emotional support service delivered by the Royal Scottish Agricultural Benevolent Institution (RSABI). The feasibility was supplemented by process evaluation.

Methods

This feasibility study aimed to recruit 40 individuals from the farming community who were experiencing a common health problem defined as a score of >  = 8 on PHQ-9. A snowball approach was used to recruit interested individuals who had an association with farming. An initial telephone call screened for eligibility and obtained consent to randomisation to the two specified interventions, or to a thirdly group receiving a combination of both LLTTF-F and ‘Social and emotional support’. Participants were permitted to override the randomised option if they expressed a strong preference before the interventions began.

Results

Thirty-two participants provided baseline and three-month data. All three interventions showed positive improvements on PHQ-9 scores as follows: the ‘combined intervention’ mean baseline score was 18.1 compared to 12.0 at 3-month follow-up (mean change 6.1). ‘Social and emotional support’ mean baseline score was 11.3 compared to 6.7 at 3-month follow-up (mean change 4.6). ‘LLTTF-F CBT-based intervention only’ mean baseline score was 11.8 compared to 4.5 at 3-month follow-up (mean change 7.3). The retention rate was 81% at three months.

In a sub-group of the LLTTF-F CBT-based intervention online materials were supplemented by telephone guided support. This approach received very positive feedback.

Conclusions

Recruitment from the farming community required intense effort, and good engagement can then be retained for at least three months. There is evidence that the interventions used were feasible, and tentative evidence that they had a demonstrable effect on mental wellbeing, with the LLTTFF providing the largest effect on PHQ-9 scores.

Making English Official
Authors: Flowers Katherine S.
Published: January 2024

In communities across the US, people wrestle with which languages to use, and who gets to decide. Despite more than 67 million US residents using a language other than English at home, over half of the states in the US have successfully passed English-only policies. Drawing on archives and interviews, this book tells the origin story of the English-only movement, as well as the stories of contemporary language policy campaigns in four Maryland county governments, giving a rare glimpse into what motivates the people who most directly shape language policy in the US. It demonstrates that English-only policies grow from more local levels, rather than from nationalist ideologies, where they are downplayed as harmless community initiatives, but result in monolingual approaches to language remaining increasingly pervasive.

Towns and Commerce in Viking-Age Scandinavia
Authors: Kalmring Sven
Published: January 2024

The Viking Age, from c.750 to 1050 CE, was an era of major social change in Scandinavia. By the end of this period of sweeping transformation, Scandinavia, once a pagan periphery, had been firmly integrated into occidental Europe. Archaeological remains offer evidence of this process, which included and intertwined with Christianisation, state formation, and the dawn of urbanisation in Scandinavia. In this volume, Sven Kalmring offers an interdisciplinary and geographically wide-ranging approach to understanding the emergence of towns and commerce in Viking-age Scandinavia and their eventual demise by the end of the period. Using the towns of Hedeby, Birka, Kaupang, and Ribe as case studies, he also tracks the diverging characteristics of these urban communities against the background of traditional social structures in the Viking world. Instead of tracing the results of Viking Age urbanisation, or mapping that process by establishing economic networks, Kalmring focusses on the very reasons behind the emergence of towns, and their eventual decline.
Roman Liturgy and Frankish Creativity
Authors: Westwell Arthur
Published: January 2024

This incisive, in-depth study unearths the significance of a neglected group of early medieval manuscripts, those which transmit the Ordines Romani. These texts present detailed scripts for Christian ceremonies that narrate the gestures, motions, actions and settings of ritual performance, with particular orientation to the Roman church. While they are usually understood as liturgical, and thus lacking any particular creative flair, Arthur Westwell here foregrounds their manuscript permutations in order to reveal their extraordinary dynamism. He reflects on how the Carolingian Church undertook to improve liturgical practice and understanding, questioning the accepted idea of a “reform” aimed at uniformity led by the monarch. Through these manuscripts, Westwell reveals a diversity of motivations in the recording of Roman liturgy and demonstrates the remarkable sophistication of Carolingian manuscript compilers.
Who Is a True Christian?
Authors: Congdon David W.
Published: January 2024

'No true Christian could vote for Donald Trump.' 'Real Christians are pro-life.' 'You can't be a Christian and support gay marriage.' Assertive statements like these not only reflect growing religious polarization but also express the anxiety over religious identity that pervades modern American Christianity. To address this disquiet, conservative Christians have sought security and stability: whether by retrieving 'historic Christian' doctrines, reconceptualizing their faith as a distinct culture, or reinforcing a political vision of what it means to be a follower of God in a corrupt world. The result is a concerted effort 'Make Christianity Great Again': a religious project predating the corresponding political effort to 'Make America Great Again.' Part intellectual history, part nuanced argument for change, this timely book explores why the question of what defines Christianity has become, over the last century, so damagingly vexatious - and how believers might conceive of it differently in future.
Theorizing in Comparative Politics
Authors: Hyden Goran
Published: January 2024

This book addresses a pertinent issue in comparative politics: how can the discipline do analytical justice to regions of the world that differ historically from the Western experience? For decades the West has served as a baseline against which all other regions are assessed, most recently in studies of democratization. Structural differences between regions have been ignored in favour of explanations based on human agency and institutions. In Theorizing in Comparative Politics, Goran Hyden uses the countries of Africa as an empirical case to demonstrate what a structural approach adds to the comparative study of democracy. Priorities like state-building challenge the effort to shape democratic regimes and call for explanations that recognize the impact of local power dynamics on the prospects for democratic development. Informative and thoughtful, this book sheds light on issues that have been underexplored in the field in recent years.

Published: January 2024

Energy consumption in buildings, both residential and commercial, accounts for approximately 40% of all energy usage in the United States, and similar numbers are being reported from countries around the world. This significant amount of energy is used to maintain a comfortable, secure, and productive environment for the occupants. So, it is crucial that energy consumption in buildings must be optimized, all the while maintaining satisfactory levels of occupant comfort, health, and safety. Machine learning (ML) has been proven to be an invaluable tool in deriving important insights from data and optimizing various systems. In this work, we review some of the most promising ways in which ML has been leveraged to make buildings smart and energy-efficient. For the convenience of readers, we provide a brief introduction to the relevant ML paradigms and the components and functioning of each smart building system we cover. Finally, we discuss the challenges faced while implementing machine learning algorithms in smart buildings and provide future avenues for research in this field.

Background:

Despite infection control guidance, sporadic nosocomial coronavirus disease 2019 (COVID-19) outbreaks occur. We describe a complex severe acute respiratory coronavirus virus 2 (SARS-CoV-2) cluster with interfacility spread during the SARS-CoV-2 δ (delta) pandemic surge in the Midwest.

Setting:

This study was conducted in (1) a hematology-oncology ward in a regional academic medical center and (2) a geographically distant acute rehabilitation hospital.

Methods:

We conducted contact tracing for each COVID-19 case to identify healthcare exposures within 14 days prior to diagnosis. Liberal testing was performed for asymptomatic carriage for patients and staff. Whole-genome sequencing was conducted for all available clinical isolates from patients and healthcare workers (HCWs) to identify transmission clusters.

Results:

In the immunosuppressed ward, 19 cases (4 patients, 15 HCWs) shared a genetically related SARS-CoV-2 isolate. Of these 4 patients, 3 died in the hospital or within 1 week of discharge. The suspected index case was a patient with new dyspnea, diagnosed during preprocedure screening. In the rehabilitation hospital, 20 cases (5 patients and 15 HCWs) positive for COVID-19, of whom 2 patients and 3 HCWs had an isolate genetically related to the above cluster. The suspected index case was a patient from the immune suppressed ward whose positive status was not detected at admission to the rehabilitation facility. Our response to this cluster included the following interventions in both settings: restricting visitors, restricting learners, restricting overflow admissions, enforcing strict compliance with escalated PPE, access to on-site free and frequent testing for staff, and testing all patients prior to hospital discharge and transfer to other facilities.

Conclusions:

Stringent infection control measures can prevent nosocomial COVID-19 transmission in healthcare facilities with high-risk patients during pandemic surges. These interventions were successful in ending these outbreaks.
National survey of infectious disease fellowship program directors: A call for subspecialized training in infection prevention and control and healthcare epidemiology
Authors: Winkler Marisa L. , Paras Molly L. , Wright Sharon B. , Shenoy Erica S.
Published: January 2024

Objective:

The importance of infection prevention and control and healthcare epidemiology (IPC/HE) in healthcare facilities was highlighted during the COVID-19 pandemic. Infectious disease (ID) clinicians often hold leadership positions in IPC/HE teams; however, there is no standard for training or certification of ID physicians specializing in IPC/HE. We evaluated the current state of IPC/HE training in ID fellowship programs.

Design:

A national survey of ID fellowship program directors was conducted to assess current IPC/HE training components in programs and plans for expanded offerings.

Setting and participants:

All ID fellowship program directors in the United States and Puerto Rico.

Methods:

Surveys were distributed using Research Electronic Data Capture (REDCap) to program directors in March 2023, with 2 reminder emails; the survey closed after 4 weeks.

Results:

Of 166 program directors, 54 (32.5%) responded to the survey. Among respondent programs, 49 (90.7%) of 54 programs reported didactic training in IPC/HE averaging 4.4 hours over the course of the fellowship. Also, 18 (33.3%) of 54 reported a dedicated IPC/HE training track. Furthermore, 23 programs (42.6%) reported barriers to expanding training. There was support (n = 47, 87.0%) for formal IPC/HE certification from a professional society within the standard fellowship.

Conclusions:

Despite the COVID-19 pandemic highlighting the need for ID medical doctors with IPC/HE expertise, formal training in ID fellowship remains limited. Most program directors support formalization of IPC/HE training by a professional organization. Creation of standardized advanced curriculums for ID fellowship training in IPC/HE could be considered by the Society of Healthcare Epidemiology of America (SHEA) to grow, retain, and enhance the IPC/HE physician workforce.
On the Kolmogorov constant explicit form in the theory of discrete-time stochastic branching systems
Authors: Imomov Azam A. , Murtazaev Misliddin S.
Published: January 2024

We consider a discrete-time population growth system called the Bienaymé–Galton–Watson stochastic branching system. We deal with a noncritical case, in which the per capita offspring mean
$m\neq1$
. The famous Kolmogorov theorem asserts that the expectation of the population size in the subcritical case
$m<1$
on positive trajectories of the system asymptotically stabilizes and approaches
${1}/\mathcal{K}$
, where
$\mathcal{K}$
is called the Kolmogorov constant. The paper is devoted to the search for an explicit expression of this constant depending on the structural parameters of the system. Our argumentation is essentially based on the basic lemma describing the asymptotic expansion of the probability-generating function of the number of individuals. We state this lemma for the noncritical case. Subsequently, we find an extended analogue of the Kolmogorov constant in the noncritical case. An important role in our discussion is also played by the asymptotic properties of transition probabilities of the Q-process and their convergence to invariant measures. Obtaining the explicit form of the extended Kolmogorov constant, we refine several limit theorems of the theory of noncritical branching systems, showing explicit leading terms in the asymptotic expansions.
Beyond the Western Conceptions with François Jullien: The Process of Leadership Informed by the Chinese Shi 勢 as Organizational Propensity
Authors: Yue Feng , Persson Sybille , Wasieleski David
Published: January 2024

This conceptual paper examines the considerable scope of leadership theories built from literature originating in the West to focus on the ‘process’ of leadership. By opening the door to include traditional Chinese thought, the worldview of Western tradition is challenged using the work of philosopher and sinologist François Jullien. Chinese culture views process as the basis of transformation and renewal in the world. It is explained through ‘the propensity of things’ in relation to European ontology and causality. Recognizing the evolving nature of reality through the generic Chinese notion of shi 勢, which serves as a conceptual tool for Jullien, leadership process is understood as an aspect of organization propensity. Shi 勢 is then recognized as a leading force encompassing human agency that is able to open a new avenue for research nurturing the emerging quantum phase of leadership.
P.F. Strawson on Punishment and the Hypothesis of Symbolic Retribution
Authors: Burms Arnold , Cuypers Stefaan E. , de Mesel Benjamin
Published: January 2024

Strawson's view on punishment has been either neglected or recoiled from in contemporary scholarship on ‘Freedom and Resentment’ (FR). Strawson's alleged retributivism has made his view suspect and troublesome. In this article, we first argue, against the mainstream, that the punishment passage is an indispensable part of the main argument in FR (section 1) and elucidate in what sense Strawson can be called ‘a retributivist’ (section 2). We then elaborate our own hypothesis of symbolic retribution to explain the continuum between moral reactive attitudes and punishment that Strawson only adumbrates (section 3). After this justification of the punitive response to wrongdoing, we compare and contrast our specific kind of retributivist hypothesis with other positions in the so-called ‘new retributivism’ (section 4). Our hypothesis differs from other subvarieties of expressive retributivism in putting centre stage the idea of punishment as taking up a reverential stance towards the victim.
