AbstractBACKGROUNDFacultative bacterial endosymbionts have the potential to influence the interactions between aphids, their natural enemies, and host plants. Among the facultative symbionts found in populations of the grain aphid Sitobion avenae in central Chile, the bacterium Regiella insecticola is the most prevalent. In this study, we aimed to investigate whether infected and cured aphid lineages exhibit differential responses to wheat cultivars containing varying levels of the benzoxazinoid DIMBOA (2,4‐dihydroxy‐7‐methoxy‐2H‐1,4‐benzoxazin‐3(4H)‐one), which is a xenobiotic compound produced by plants. Specifically, we examined the reproductive performance responses of the most frequently encountered genotypes of Sitobion avenae when reared on wheat seedlings expressing low, medium, and high concentrations of DIMBOA.RESULTSOur findings reveal that the intrinsic rate of population increase (rm) in cured lineages of Sitobion avenae genotypes exhibits a biphasic pattern, characterized by the lowest rm and an extended time to first reproduction on wheat seedlings with medium levels of DIMBOA. In contrast, the aphid genotypes harbouring Regiella insecticola display idiosyncratic responses, with the two most prevalent genotypes demonstrating improved performance on seedlings featuring an intermediate content of DIMBOA compared to their cured counterparts.CONCLUSIONThis study represents the first investigation into the mediating impact of facultative endosymbionts on aphid performance in plants exhibiting varying DIMBOA contents. These findings present exciting prospects for identifying novel targets for aphid control by manipulating the presence of aphid symbionts. © 2023 Society of Chemical Industry.
Event‐triggered disturbance rejection tracking for surface ships under stochastic disturbances and actuator saturation
Authors: Hu Xin , Wei Xinjiang , Zhang Huifeng , Gong Qingtao , Sun Sixiang 
Published: December 2023

SummaryThis paper focuses on the problem of the event‐triggered disturbance rejection tracking control for marine surface ships with ocean stochastic disturbances under actuator saturation effects. The ocean stochastic disturbances are described by the first‐order Markov stochastic process. The event‐triggered disturbance rejection tracking control is built through incorporating a stochastic disturbance observer and an auxiliary dynamic filter with the event‐triggered vectorial backstepping framework. A stochastic disturbance observer is established to provide stochastic disturbance estimations on‐line. Then, an auxiliary dynamic filter employs the commanded control derivation vector to modify the feedback control errors on‐line so as to preserve the disturbance rejection tracking control performance under adverse saturation effects. The event‐triggered control protocol involving tracking errors and commanded control derivations is designed to reduce the excessive wear and tear of propellers and thrusters in the presence of ocean stochastic disturbances. Illustrative simulations on a 1:70 model ship demonstrate the effectiveness of the proposed control scheme.

Published: December 2023

AbstractDespite that extensive efforts have been dedicated to the search for advanced catalysts to boost the electrocatalytic nitrobenzene reduction reaction (eNBRR), its progress is severely hampered by the limited understanding of the relationship between catalyst structure and its catalytic performance. Herein, this review aims to bridge such a gap by first analyzing the eNBRR pathway to present the main influential factors, such as electrolyte feature, applied potential, and catalyst structure. Then, the recent advancements in catalyst design for eNBRR are comprehensively summarized, particularly about the impacts of chemical composition, morphology, and crystal facets on regulating the local microenvironment, electron and mass transport for boosting catalytic performance. Finally, the future research of eNBRR is also proposed from the perspectives of performance enhancement, expansion of product scope, in‐depth understanding of the reaction mechanism, and acceleration of the industrialization process through the integration of upstream and downstream technologies.
Enterprise architecture contribution in distributed agile software development
Authors: Alzoubi Yehia Ibrahim , Mishra Alok 
Published: December 2023

AbstractGeographically distributed agile development may experience a high failure rate due to communication issues, which has a negative influence on project performance. One suggested solution in the literature is to enhance both communication and project performance by implementing agile enterprise architecture. However, the empirical evidence that supports this claim is still scarce. To address this gap, this study empirically explores the role of agile enterprise architecture as an artifact in distributed agile development. The findings of an in‐depth qualitative case study from a dispersed agile development organization that involves teams distributed over three locations are used in this work. Over 2 months, data was gathered by interviewing 12 key members of the team and watching three Sprint sessions of agile software development. Text analysis qualitative approach was used to analyze the data. The findings imply that agile enterprise architecture has a positive effect on distributed agile software development communication, quality, and functionality. Agile enterprise architecture may also support on‐time completion, but a trade‐off with on‐budget may be necessary. These findings provide valuable insights, frameworks, and best practices that support organizations in achieving greater agility, collaboration, and success in their distributed software development initiatives. As this is one of the first studies to look at the influence of agile enterprise architecture on distributed agile software development communication and performance, further research is needed to confirm and expand on the conclusions of this study.

Published: December 2023

AbstractEngaging in frequent, meaningful conversation during the early years of schooling is foundational for children's literacy development. Specifically, developing oral language through daily conversations is essential for language comprehension, and eventually, reading comprehension. In this article, we discuss how teachers can use the Strive‐for‐Five framework to strategically engage students (preschool through Grade 1) in meaningful back‐and‐forth conversations. Using Scarborough's Reading Rope, we illustrate how teachers can elevate the quality of conversations to enhance literacy knowledge, vocabulary, verbal reasoning, background knowledge, and language structures.

AbstractIntroductionAccess to Liver transplantation (LT) can be affected by several barriers, resulting in delayed referral and increased risk of mortality due to complications of the underlying liver disease.AimTo assess the clinical characteristics and outcomes of patients with acute or chronic liver disease referred using an integrated referral program.Materials and MethodsAn integrated referral program was developed in 1 October 2017 based on email addresses and a 24/7 telephone availability. All consecutive adult patients with liver disease referred for the first time using this referral program were prospectively collected until 1 October 2021. Characteristics and outcomes of inpatients were compared with a historical cohort of patients referred without using the integrated referral program (1 October 2015—1 October 2017). Patients were further divided according to pre‐ and post‐Covid‐19 pandemic.ResultsTwo hundred eighty‐one referred patients were considered. End stage liver disease was the most common underlying condition (79.3%), 50.5% of patients were referred as inpatients and 74.7% were referred for LT evaluation. When inpatient referrals (n = 142) were compared with the historical cohort (n = 86), a significant increase in acute liver injury due to drugs/herbals and supplements was seen (p = 0.01) as well as an increase in End stage liver disease due to alcohol‐related liver disease and NASH, although not statistically significant. A significant increase in referrals for evaluation for Trans‐jugular intrahepatic portosystemic shunt placement was seen over time (5.6% vs. 1%; p = 0.01) as well as for LT evaluation (84.5% vs. 81%; p = 0.01). Transplant‐free survival was similar between the study and control groups (p = 0.3). The Covid‐19 pandemic did not affect trends of referrals and patient survival.ConclusionsThe development of an integrated referral program for patients with liver disease can represent the first step to standardize already existing referral networks between hub and spoke centers. Future studies should focus on the timing of referral according to different etiologies to optimize treatment options and outcomes.
Current Business Model Practices in Energy Master Planning for Regions, Cities and Districts
Authors: Haase Matthias , Konstantinou Thaleia 
Published: December 2023

AbstractRoughly 97% of the European Union (EU) building stock is not considered energy efficient, and 75–85% of it will still be in use in 2050 (Artola et al., Boosting building renovation: What potential and value for Europe? 2016). Residential buildings account for around two thirds of final energy consumption in European buildings. The rate at which new buildings either replace the old stock or expand the total stock is about 1% per year. Similarly, the current renovation rate of existing buildings in the EU is about 1–2% of the building stock renovated each year. Renovation strategies on building levels need to be derived from a combination of energy efficiency upgrades to buildings and the use of renewable energy to decarbonize the energy supply, on a district or city scale. IEA EBC Annex 75 subtask D2 focuses on promoting cost-effective building renovation at district level combining energy efficiency and renewable energy systems, by focusing on the business models that can make implementation possible. This paper intends to provide an overview of the business model archetypes that can support the development of district demand and/or supply of energy-efficient building renovations and/or renewable energy solutions by targeting various types of stakeholders. It builds upon existing literature to gain insights into the current distributed energy business model landscape. Further, implementation strategies are identified that focus on a holistic evaluation of the expected energy and CO2 performance of the site and optimized infrastructure investment pathways.
Commoning Practices Along Streetscapes
Authors: Ravazzoli Elisa 
Published: December 2023

AbstractIn many cities around the world, similar stakeholders are collectively implementing initiatives that aim to address common problems, satisfy similar unmet needs, and contribute to the creation of more socially just and ecologically sustainable communities. Among the different types of action, commoning practices propose alternative forms of caring, sharing, protesting, producing, consuming, and occupying, where resources are collectively produced, owned, managed, or distributed. This paper seeks to theoretically reflect on the transformative power of commoning occurring on streets to tackle contemporary challenges and aims to suggest a framework for the socio-spatial analysis of commoning practices on streets.
New Technologies and Public Spaces: Supporting Sustainable Urban Policies
Authors: Sepe Marichela 
Published: December 2023

AbstractNew technologies add value to public spaces if these are used to support the knowledge of a place and its use. The presence of wireless, multimedia support, apps and different ICT tools constitute elements, which can support the knowledge aspects of the place with its different characteristics and can be designed in a logic of integration with other infrastructure and networks in the city. Furthermore, the presence on social media, even if not exhaustive—as the presence of that public space as a background to a photo does not guarantee that it is a pleasant and successful space—offers, however, within a more comprehensive framework of information, data on the type and quantity of users and their perception of it. Indeed, new technologies in their different forms become more and more important tools to provide deeper knowledge of the place, participation, and to address sustainable urban policies. Starting from these premises, the aim of this work, carried out in the framework of the research project “PRIN2020 #20209F3A37”, within the ISMed-CNR Unit with the author’s responsibility and the related Sapienza Università di Roma-ISMed-CNR agreement, is to illustrate the positive influence of ICT tools on the use of both indoor and outdoor public spaces by: revitalizing them; increasing the possibilities of use as well as contributing to greater social cohesion; and supporting sustainable urban policies. By way of examples, two emblematic case studies of public spaces will be illustrated using an original and an ad hoc database.
Life Course Studies and Biographical Research: Exploring the Individual-Society Relationship
Authors: Nilsen Ann 
Published: December 2023

AbstractIn this chapter the many ways in which the individual-society relationship has been approached in the history of sociology are addressed. The micro-macro distinction is discussed as an early conceptualisation of this relationship. In Thomas and Znaniecki’s pioneering work they made a distinction between ‘values’ and ‘attitudes’ that was considered an early attempt at constructing notions to discuss this issue in biographical research. The prominence of the agency-structure pair of concepts since the 1990s in the vocabulary to discuss the relationship between individuals and society is discussed in relation to the historical contexts of their origin. The section outlines arguments from some of the prominent sociologists who have written about the topic. Gendered aspects of concepts are seldom addressed in mainstream sociological theoretical discussions. A section that discusses this topic in its own right is included in this chapter. It sets notions of gendered agency within the historical contexts of debates that addressed them. Differences between the structure-agency divide on the one hand, and the history-biography dynamic on the other are discussed in the fourth section of the chapter. It also gives an overview of the diversity of approaches to the history-biography dynamic in biographical life course research.
Time and Temporality in Biographical Life Course Research
Authors: Nilsen Ann 
Published: December 2023

AbstractThis chapter discusses the topics of time and temporality in biographical research. The Chapter addresses the centrality of Mead’s writings. His notion of the temporal self was of particular relevance for this tradition. A section on historical time discusses the impact of period specific historical events on intergenerational relations and on the individual level. Family time is addressed in Tamara Hareven’s framework as an intermediary temporality between biographical and historical time. Discussions on intergenerational time explore topics such as social mobility and set these in an historical framework that demonstrate how biographical studies can add layers of knowledge about the processes involved that quantitative approaches miss. At the biographical level life course phases are addressed in relation to transitions and variations across cultural and structural contexts. Specific attention is paid to the phase of adulthood since it has largely had a kind of taken-for-granted definition without much attention to variations by gender and social class over historical time. A section on gender and time sets discussions about this theme in its historical context and extends the topic to include temporal aspects of biographical interviews and gendered narratives. In this section empirical examples from my own and other research are used to exemplify the arguments addressed.
The Future as a Topic in Biographical Life Course Approaches
Authors: Nilsen Ann 
Published: December 2023

AbstractThe relevance of a biographical approach to studies about the future is the topic of this chapter. In a discussion that takes its point of departure in theories of time and temporality, the significance of particular aspects of historical periods for what topics about the future are deemed research-worthy is addressed. The chapter addresses how ideas about Progress impacted on notions of time and temporality during earlier historical periods. Empirical studies discussed in this chapter demonstrate their embeddedness in specific circumstances and particular historical periods. These research topics thus provide insights into how changes at the structural level, be they environmental problems such as climate change, pandemics, or credit crises, in any present are woven into and become topics in individual biographical accounts. The early studies of women and time and gendered thoughts about the future, for instance, originated in a period when changes in gender relations in all areas of social life happened at a rapid pace in the Scandinavian countries in particular. The chapter shows that whilst gender, age and social class are essential analytical elements of sociological analysis that transcend historical periods, the contexts of their impact are diverse and varied.
Methodological and Other Controversies
Authors: Nilsen Ann 
Published: December 2023

AbstractThis chapter addresses methodological and other controversies in the biographical research tradition. Two strands of methodological debates have run parallel; the quantitative-qualitative divide that foregrounded methodological issues, and the other debate originating in the ‘cultural turn’ in the social sciences, that put epistemological questions centre stage. The quantitative-qualitative dispute has early origins. The discussion as it relates to life course and biographical research have been a constant since the origin of this approach. The methodological divide has persisted over the years and is also related to epistemological debates that have created dividing lines within qualitative approaches. A section discusses the meeting between the different approaches to qualitative biographical research in the social sciences and the humanities. The heated discussions from the 1980s onwards, that were in reality addressing themes in the philosophy of science, are presented in their contemporary contexts. Another line of debate is about notions and attention to historical time and is addressed in the section called ‘From history as periods to history as epoch’. Theoretical notions such as ‘the individualisation thesis’ and a ‘de-standardisation’ of life courses are terms associated with notions of history in epochal terms such as ‘late modernity’ and show how this vocabulary became influential.
Reflections
Authors: Nilsen Ann 
Published: December 2023

AbstractThis chapter starts with general discussions about divides in the wider research community and then narrows down the focus to the biographical life course approach and the various suggestions that have been put forward for bridging methodological divides. Mixed methods strategies across the quantitative-qualitative gap is the title of a section that presents different research designs in such studies that make use of both quantitative and qualitative material. It discusses challenges and potential barriers against incorporating both types of data along a continuum of statistical techniques for causal analyses on the one end, and biographical material for exploring social processes, on the other. Examples from empirical research illustrate the points raised. Questions of quality in biographical life course research is the topic of a separate section that underlines how different research strategies and approaches invite specific types of questions in relation to e.g., generalisability. The chapter ends with some general reflections inspired by research from this approach in contemporary society.
Factorization of covariant Feynman graphs for the effective action
Authors: von Gersdorff Gero 
Published: December 2023

Abstract
We prove a neat factorization property of Feynman graphs in covariant perturbation theory. The contribution of the graph to the effective action is written as an integral over Schwinger parameters whose integrand is a product of a massless scalar momentum integral that only depends on the basic graph topology, and a background-field dependent piece that contains all the information of spin, gauge representations, masses etc. We give a closed expression for the momentum integral in terms of four graph polynomials whose properties we derive in some detail. Our results can also be useful for standard (non-covariant) perturbation theory.
Investigation of surface imperfection in freeform optics with high-order XY polynomial design

Published: December 2023

AbstractFreeform surfaces find potential applications in optics but pose new challenges for manufacturing and functional testing. A basic description of such surfaces is observed in terms of surface spatial frequencies which have been altered as a result of evolution in the fabrication of optics. While mid-spatial-frequency (MSF) errors arising from manufacturing and metrology processes are well documented, our investigation reveals that such errors originate not only during these stages but also during the surface construction at the design phase, particularly for high-order XY polynomial optical surfaces. The presence of MSF errors can significantly affect the performance of high-performance optical systems across various applications. The study discussed in this paper focuses on the relationship between the resolution of the design dataset of freeform surfaces with high-order polynomials and the subsequent surface imperfections in the production of precision optics. The main contributions of this investigation are the identification of MSF errors at surface construction of the design phase and the control over the MSF errors in design dataset using the 2nd-order Gaussian filtration which will bridge the gap between freeform optics design and ultra-precision manufacturing.
