System of systems engineering governance framework for digital transformation: A case study of an Australian large government agency
Authors: Papavasiliou Samantha , Gorod Alex , Reaiche Carmen 
Published: September 2023

AbstractCurrent swift technological advances are significantly impacting how organizations operate and services are provided. Even with the multiple benefits for organizations that undergo digital transformation, the majority of transformation initiatives fail due to the challenges that arise. A primary reason for these failures links back to the lack of effective governance framework to support effective digital transformation efforts. This paper proposes such a framework through a system of systems engineering approach to understand the various constituent systems involved in digital transformation efforts and their interactive and emergent behaviors. The application and usefulness of the framework were demonstrated as part of a digital transformation initiative in an Australian Large Government Agency and documented as a case study.

Published: September 2023

AbstractBackgroundOpen spina bifida is an uncommon malformation in animals, and there is a lack of imaging, clinical, and pathological characterisation of this condition in dogs.ObjectiveOpen spina bifida is rarely observed in animals due to high levels of perinatal mortality and frequent euthanasia. To the best of our knowledge, we present the first case of spina bifida in a dog was diagnosed in‐utero and then followed post‐partum.MethodsA 3‐year‐old Poodle was presented with twin pregnancy. Radiographic and ultrasonographic findings were suggestive of vertebral malformation and open spina bifida with myelomeningocele in one foetus. Conservative treatment was given but the puppy died 3 days after birth. Thereafter, anatomical and histopathological analysis of several organs was performed to characterise the disease.ResultsWhen the twins were born, one puppy had a linear dorsal midline cutaneous defect extending from the level of vertebrae L2–L6. R Radiographic examination showed several congenital vertebral malformations involving the thoracic segment, lumbar segment, sacrum and scapula. Histopathological examinations confirmed the presence of open spina bifida and identified additional abnormalities in several internal organs.ConclusionsThis case presents a complete characterisation of open spina bifida, before birth and after death, using imaging and histopathology techniques.
K7In4As6 and K3InAs2 ‐ Two more Zintl phases showing the rich variety of In‐As polyanion structures
Authors: Boyko Marina , Hlukhyy Viktor , Fässler Thomas F. 
Published: September 2023

AbstractBinary phases of triel (Tr) and pentel (Pn) elements (III‐V semiconductors) represent a unique compound class due to their tunable intrinsic band gap in dependency of the element combination. We report here on two new compounds in the ternary system K−In−As. In K3InAs2 the edge‐sharing tetrahedral InAs4 units are connected via opposed edges of the tetrahedra forming linear [InAs2]3− chains and are thus iso(valence)‐ electronic with SiS2. In K7In4As6, the InAs4 tetrahedra are connected via neighboring edges of the tetrahedra forming zig‐zag chains. These chains are linked in two directions through dimeric [As3In−InAs3] units. Both reported Zintl phases extend the number of structures that possess the same In−As ratio. In K3InAs2 a one‐dimensional polyanion in contrast to known Na3InAs2 comprising a three‐dimensional polyanion structure is found. K7In4As6 forms together with the known phases K2In2As3 and K3In2As3 a series of Zintl phases with the ratio In : As=2 : 3. Even though the three phases differ only slightly in their valence electron concentration (VEC) of the polyanion, the VECs have a strong influence on the structures. Syntheses, crystal structures and the electronic band structures are reported. The compounds are discussed in the context of the Zintl concept.
Multimodal Chat-Based Apps: Enhancing Copresence When Writing
Authors: Bowen Tracey , Whithaus Carl 
Published: September 2023

AbstractThis chapter examines how digital platforms and social media may be integrated as part of academic writing processes. These digital tools can be used to facilitate students’ development as writers who are agile across modes of text production, collaboration, and dissemination. Writing on multimodal apps and platforms such as WhatsApp and Discord have encouraged students to write in ways that are collective and collaborative. Students are taking up brainstorming and “pre-writing” activities on these public platforms as a way tocometo writing in virtual contexts in the copresence of others. These forms of “prewriting” are increasingly becoming part of writing processes and bleeding over into how students’ final academic pieces of writing take shape. Students are not only using these social writing processes and genres in their academic writing but they are also becoming digital content creators as they enter their professional spheres.
Information Retrieval and Knowledge Extraction for Academic Writing
Authors: Benites Fernando 
Published: September 2023

AbstractThe amount of unstructured scientific data in the form of documents, reports, papers, patents, and the like is exponentially increasing each year. Technological advances and their implementations emerge at a similarly fast pace, making for many disciplines a manual overview of interdisciplinary and relevant studies nearly impossible. Consequently, surveying large corpora of documents without any automation, i.e. information extraction systems, seems no longer feasible. Fortunately, most articles are now accessible through digital channels, enabling automatic information retrieval by large database systems. Popular examples of such systems are Google Scholar or Scopus. As they allow us to rapidly find relevant and high-quality citations and references to previous work, these systems are particularly valuable in academic writing. However, not all users are aware of the mechanisms underlying relevance sorting, which we will address in this chapter. For example, in addition to searching for specific terms, new tools facilitate the discovery of relevant studies by using synonyms as well as similar works/citations. The near future holds even better tools for the creation of surveys, such as automatic summary generation or automatic question-answering systems over large corpora. In this chapter, we will discuss the relevant technologies and systems and their use in the academic writing context.
On the coupling of axion-like particles to the top quark
Authors: Esser Fabian , Madigan Maeve , Sanz Veronica , Ubiali Maria

Abstract
In this paper we explore the coupling of a light axion-like particle (ALP) to top quarks. We use high-energy LHC probes, and examine both the direct probe to this coupling in associated production of a top-pair with an ALP, and the indirect probe through loop-induced gluon fusion to an ALP leading to top pairs. Using the latest LHC Run II data, we provide the best limit on this coupling. We also compare these limits with those obtained from loop-induced couplings in diboson final states, finding that the $$ t\overline{t} $$

+MET channel is the best current handle on this coupling.
Clostridium botulinum C3bot mediated effects on cytokine-induced psoriasis-like phenotype in full-thickness skin model
Authors: Rohrbeck Astrid , Bruhn Vanessa Anna , Hussein Nali , Hagemann Sandra , Just Ingo 
Published: September 2023

AbstractClostridium botulinum C3 exoenzyme (C3bot) exclusively inhibits RhoA, B and C by ADP-ribosylation and is therefore used as a cell-permeable tool for investigating the cellular role of these Rho-GTPases. Rho-GTPases represent a molecular switch integrating different receptor signalling to downstream cascades including transcriptional cascades that regulate various cellular processes, such as regulation of actin cytoskeleton and cell proliferation. C3bot-induced inhibition of RhoA leads to reorganization of the actin cytoskeleton, morphological changes, and inhibition of cell proliferation as well as modulation of inflammatory response. In this study, we characterized the C3bot-mediated effects on a full-thickness skin model exhibiting a psoriasis-like phenotype through the addition of cytokines. Indeed, after the addition of cytokines, a decrease in epidermal thickness, parakeratosis, and induction of IL-6 was detected. In the next step, it was studied whether C3bot caused a reduction in the cytokine-induced psoriasis-like phenotypes. Basal addition of C3bot after cytokine induction of the full-thickness skin models caused less epidermal thinning and reduced IL-6 abundance. Simultaneous basal incubation with cytokines and C3bot, IL-6 abundance was inhibited, but epidermal thickness was only moderately affected. When C3bot was added apically to the skin model, IL-6 abundance was reduced, but no further effects on the psoriasis-like phenotype of the epidermis were observed. In summary, C3bot inhibits the cytokine-induced expression of IL-6 and thus may have an impact on the pro-inflammatory immune response in the psoriasis-like phenotype.
Dancing in virtual reality as an inclusive platform for social and physical fitness activities: a survey

Published: September 2023

AbstractVirtual reality (VR) has recently seen significant development in interaction with computers and the visualization of information. More and more people are using virtual and immersive technologies in their daily lives, especially for entertainment, fitness, and socializing purposes. This paper presents a qualitative evaluation of a large sample of users using a VR platform for dancing ($$N=292$$

N

); we study the users’ motivations, experiences, and requirements for using VR as an inclusive platform for dancing, mainly as a social or physical activity. We used an artificial intelligence platform (OpenAI) to extract categories or clusters of responses automatically. We organized the data into six user motivation categories: fun, fitness, social activity, pandemic, escape from reality, and professional activities. Our results indicate that dancing in virtual reality is a different experience than in the real world, and there is a clear distinction in the user’s motivations for using VR platforms for dancing. Our survey results suggest that VR is a tool that can positively impact physical and mental well-being through dancing. These findings complement the related work, help in identifying the use cases, and can be used to assist future improvements of VR dance applications.

AbstractThe emergence of digital media has changed the way people live and learn. In the context of the new era, digital media is gradually integrating into people’s life and learning. Digital media contains massive images, and fine-grained image recognition for digital media has become an important topic. The challenge of fine-grained image recognition is that the difference between different categories is small, and the difference between the same categories is sometimes large. This work designs a fine-grained image recognition based on feature enhancement (FIRFE). This extracts as much information as possible from fine-grained images under weak supervision to improve the recognition accuracy. When the existing methods extract image features, the feature extraction other than the most significant local feature is not enough. This deals with local features alone and ignores the relationship between features. First, this paper designs a feature enhancement and suppression module to process image features. Secondly, this paper designs pyramid residual convolution. This uses different scale convolution kernels to capture different levels of features in the scene. Thirdly, this paper uses the softpool method to rationally allocate the information weight in the pooling process. Fourth, this paper uses feature focus module to mine more features. This focuses on obtaining similar information in multiple local features as discriminant features to further improve the recognition. Fifthly, this paper carried out systematic experiments on the designed method. The proposed method achieves 94.3%/95.7% accuracy, 92.9%/94.1% recall, and 91.4%/92.2% F1 score on different datasets. This verified the superiority of this method for fine-grained image recognition of digital media.
Emerging extreme heat conditions as part of the new climate normal
Authors: Zittis George , Lazoglou Georgia , Hadjinicolaou Panos , Lelieveld Jos 
Published: September 2023

AbstractAs a result of global warming, extreme heat conditions have become more frequent and severe. This will likely continue or accelerate in the future, particularly under high radiative forcing scenarios. In the present study, based on an ensemble of global climate model simulations, we identify the absolute historical extremes expressed by several temperature indices. Considering projections under two future pathways (SSP1$$-$$
-
2.6, SSP5$$-$$
-
8.5), we investigate to what extent extreme heat conditions will become predominant during the rest of the century. The timing of a transition to prevailing hot weather extremes is critical for the development of mitigation and adaptation strategies; therefore, we also identify the projected first year of such a transition, as well as the persistence in subsequent decades. Different aspects of heat extremes are investigated, including both maximum and minimum temperature. For some climate zones, our results highlight that regardless of mitigation efforts, hot weather conditions will be at least similar but likely more harsh compared to historical extremes within the following decades. By the end of the century, under a business-as-usual pathway, successive years will be much more extreme than the most severe conditions in the recent past virtually everywhere.
Regulation of alveolar macrophage death in pulmonary fibrosis: a review
Authors: Yang Ganghao , Yang Yang , Liu Yiping , Liu Xiaoshu 
Published: September 2023

AbstractPulmonary fibrosis (PF) is a disease in which excessive extracellular matrix (ECM) accumulation occurs in pulmonary mesenchyme, which induces the destruction of alveolar structures and poor prognosis. Macrophage death is responsible for ECM accumulation after alveolar epithelial injury in PF. Depending on the local micro-environments, macrophages can be polarized to either classically activated (M1) or alternatively activated (M2) macrophage phenotypes. In general, M1 macrophages can promote inflammation and sterilization, stop the continuous damage process and prevent excessive repair, while M2 macrophages are anti-inflammatory and promote tissue repair, and excessive M2 macrophage activity may inhibit the absorption and degradation of ECM. Emerging evidence has revealed that death forms such as pyroptosis mediated by inflammasome affect polarization direction and ultimately lead to the development of PF. Pharmacological manipulation of macrophages death signals may serve as a logical therapeutic strategy for PF. This review will focus on the current state of knowledge regarding the regulation and underlying mechanisms of macrophages and their mediators in the influence of macrophage death on the development of PF. We expect to provide help in developing effective therapeutic strategies in clinical settings.
Ecosystem health and malfunctions: an organisational perspective
Authors: Sfara Emiliano , El-Hani Charbel N. 
Published: September 2023

AbstractA recent idea of “ecosystem health” was introduced in the 1970s and 1980s to draws attention to the fact that ecosystems can become ill because of a reduction of properties such as primary productivity, functions and diversity of interactions among system components. Starting from the 1990s, this idea has been deeply criticized by authors who argued that, insofar as ecosystems show many differences with respect to organismic features, these two kinds of systems cannot share a typical organismic property such as health. In recent years, an organisational approach in philosophy of biology and ecology argued that both organisms and ecosystems may share a fundamental characteristic despite their differences, namely, organisational closure. Based on this kind of closure, scholars have also discussed health and malfunctional states in organisms. In this paper, we examine the possibility of expanding such an organisational approach to health and malfunctions to the ecological domain. Firstly, we will see that a malfunction is related to a lower effectiveness in the functional behaviour of some biotic components with respect to other systemic components. We will then show how some introduced species do not satisfactorily interact in an organisational closure with other ecosystem components, thus posing a threat to the self-maintenance of the ecosystem in which they are found. Accordingly, we will argue that an ecosystem can be said to be healthy when it is a vital environment organisationally grounded on its intrinsic capacity to ensure, under favourable conditions, appropriate functional behaviours for ecosystem components and ecosystem self-maintenance.
School Social Work in Sweden—Who are the Children in Counselling, and What Support are They Offered? A Protocol Study About Individual Counselling in Elementary Schools
Authors: Kjellgren Maria , Lilliehorn Sara , Markström Urban 
Published: September 2023

Abstract
The overall aim of the present study is to describe and explore the characteristics and content of school social worker’s (SSWs) individual counselling with children as these are imprinted in session protocols collected at Swedish elementary schools. Specific focus is placed on the character of the children’s concerns, the content of the SSW’s helping strategies, and challenges related to the alliance between the SSW and the children as experienced by the SSW. The study was based on data from a survey protocol of 20 SSW’s daily practice regarding their experiences in counselling children and adolescents. The data consisted of 193 protocols from the same number of unique individual sessions. Data were analysed through quantitative descriptive statistics. The data also contained a large proportion of open-ended textual answers, which were analysed through a qualitative summative content analysis. The counselling strategies were primarily divided into three parts, namely coaching, processing, and assessing. The most common practice elements used included elements of empowerment, alliance and relationship, and hope and trust. In counselling children, SSWs identified a broad range of problems in children’s overall lives. Many children suffered from their home situations, which also impinged upon the SSWs, who were affected by the children’s life narrative. Our results can help inform SSW policy and practices as SSWs assist vulnerable children through individual counselling that corresponds to their help-seeking behaviour and by offering a space for alliances and relationships.
Endowments, expectations, and the value of food safety certification: experimental evidence from fish markets in Nigeria
Authors: Shikuku Kelvin Mashisia , Bulte Erwin , Lagerkvist Carl Johan , Tran Nhuong 
Published: September 2023

AbstractWe study the impact of endowments and expectations on reference point formation and measure the value of food safety certification in the context of fish trading on real markets in Nigeria. In our field experiment, consumers can trade a known food item for a novel food item that is superior in terms of food safety––or vice versa. Endowments matter for reference point formation, but we also document a reverse endowment effect for a subsample of respondents. The effect of expectations about future ownership is weak and mixed. While expectations seem to affect bidding behavior for subjects “trading up” to obtain the certified food product (a marginally significant effect), it does not affect bids for subjects “trading down” to give up this novel food item. Finally, willingness to pay for safety certified food is large for our respondents—our estimate of the premium is bounded between 37 and 53% of the price of conventional, uncertified food.
What do we know about interventions to improve educator wellbeing? A systematic literature review
Authors: Cann Rachel , Sinnema Claire , Rodway Joelle , Daly Alan J. 
Published: September 2023

AbstractThis systematic literature review summarises the research into interventions intended to improve the wellbeing of educators in the early childhood to secondary sectors. A search of articles published between 2000 and 2020 yielded 23 articles that met our inclusion criteria. Studies were included if they collected quantitative or qualitative data about educator wellbeing pre-intervention and post-intervention from the same group(s) of educators. We classified articles into five categories based on their content: multi-foci (several content areas included in a program), mindfulness, gratitude, professional development (classroom practice oriented), and physical environment. The articles revealed wide variations in: wellbeing theories underpinning interventions, the phenomena measured, and the effectiveness of the interventions. In some studies wellbeing was conceptualised as the absence of negative states (such as stress), in other studies to the presence of positive states (such as satisfaction), and in a few studies as the combination of both these approaches. Some of the gaps noted across the research include the lack of attention to the role of the school climate in determining the success of an intervention, and the lack of analysis to explore whether interventions work better for some individuals than others (for example, a lack of reporting of the characteristics of participants who drop out of the interventions). Overall, the multi-foci interventions show the most promise for improving educator wellbeing.

AbstractThe main aim of this work was to develop a suitable sorbent for the separation and determination of 226Ra through 133Ba (radio tracer) in water samples using fly ash sorbent. After the modification with KMnO4 the effects of pH, competing ions, the possibility of elution, and the effect of water volume were tested. As a suitable eluent 6 mol/L HCl was chosen, while the sorbent worked best at pH 6–8. The developed method is advantageous for minimizing the time required for separation, the volume of chemicals used, and the waste generated after separation.
