Authors: Parmar Nilesh R. , Salla Sanjay R. , Khungar Hariom P. , Kondraivendhan B. 
Published: February 2024

Purpose
This study aims to characterize the behavior of blended concrete, including metakaolin (MK) and quarry dust (QD), as supplementary cementing materials. The study focuses on evaluating the effects of these materials on the fresh and hardened properties of concrete.

Design/methodology/approach
MK, a pozzolanic material, and QD, a fine aggregate by-product, are potentially sustainable alternatives for enhancing concrete performance and reducing environmental impact. The addition of different percentages of MK enhances the pozzolanic reaction, resulting in improved strength development. Furthermore, the optimum dosage of MK, mixed with QD, and mechanical properties like compressive, flexural and split tensile strength of concrete were evaluated to investigate the synergetic effect of MK and quarry dust for M20-grade concrete.

Findings
The results reveal the influence of metakaolin and QD on the overall performance of blended concrete. Cost analysis showed that the optimum mix can reduce the 7%–8% overall cost of the materials for M20-grade concrete. Energy analysis showed that the optimum mix can reduce 7%–8% energy consumption.

Originality/value
The effective utilization is determined with the help of the analytical hierarchy process method to find an optimal solution among the selected criteria. According to the AHP analysis, the optimum content of MK and quarry dust is 12% and 16%, respectively, performing best among all other trial mixes.

Authors: Foster M , Patel J , Turlach B , Anthonappa R 
Published: February 2024

AbstractBackgroundThis study aimed to investigate the (1) survival probabilities of prefabricated zirconia crowns (PZCs) placed on primary teeth and (2) identify demographic and tooth‐related factors that might affect survival probability.MethodsThis study prospectively followed children treated under general anaesthesia by a single practitioner between 2012 and 2020. Demographic variables including the age at treatment, gender and tooth‐related variables including FDI tooth number, crown size used and any procedural complications at postoperative reviews were collected.ResultsA total of 155 children involving 319 teeth with PZCs were followed up between 12 and 78 months postoperatively with a mean of 38 months. Of the 319 crowns followed, five failures were observed in three patients requiring extraction. Other procedural complications noted included fracture (n = 3), overhangs (n = 3), internal resorption (n = 5) and 24% of crowns showed signs of radiographic changes on postoperative radiographs when these were taken. Age at treatment, tooth type and need for pulp therapy were not statistically associated with clinical success (P > 0.1).ConclusionsPZCs provide an aesthetic and durable solution in the management of children with early childhood caries. This study shows very good clinical success and survival extending up to 78 months for PZCs placed on primary teeth under general anaesthesia.

AbstractThe systematic studies of composition and spatial distribution of main phases inside volume of 25 fragments of Byzantine ceramic obtained in archeological works in the Dobrudja region, Romania, have been performed using neutron diffraction and tomography, and Raman spectroscopy. The obtained structural data on the content of phases, the presence of calcite grains and pores, and the uniformity of phase spatial distribution made it possible to systematize the studied fragments and correlate them with clay sources or pottery workshop. The experimental possibilities of neutron methods of nondestructive structural diagnostics as well as the structural markers provided by them in the studies of ceramic samples are discussed.
Constructing victimhood in Canadian news coverage of HIV criminalisation: Claims‐making activities and HIV non‐disclosure
Authors: Aguinaldo Jeffrey P. , Greenspan Nicole R. 
Published: February 2024

AbstractA robust body of research has documented the representational politics of news coverage in their depiction of HIV‐positive people charged for HIV non‐disclosure. News media representations of HIV‐negative sex partners in cases of HIV non‐disclosure have received far less scholarly attention. Adopting a social constructionist perspective, this article identifies how “victims” of HIV non‐disclosure are constructed in news media. It is based on a dataset consisting of 341 news articles on HIV non‐disclosure from 14 English Canadian newspapers across the political spectrum. Victims of HIV non‐disclosure were constructed as: (1) suffering horribly, (2) morally pure and virtuous, (3) vengeful and (4) agentic and responsible for their situation. We consider how such constructions are enmeshed within arguments that establish or reject HIV non‐disclosure as a social problem. We then discuss the ways these constructions and the assumptions upon which they are based reflect broader discussions on the severity of HIV, the responsibility for HIV risk and exposure, and the contestations over the very nature of the social problem of HIV non‐disclosure. Constructions of victims that uphold HIV criminalisation have relied on assumptions of HIV as a deadly disease but de‐emphasise personal responsibility for HIV risk. By contrast, constructions of victims that, in effect, oppose HIV criminalisation have tended to minimise the harms of HIV and invoke personal responsibility for HIV risk. We suggest that both proponents and opponents of HIV criminalisation engage in the “ideology of victimhood” and thus participate in and reinforce what Best (1997) termed, the “victim industry.”
Know thy audience: Children teach basic or complex facts depending on the learner's maturity
Authors: Qiu Fanxiao Wani , Ipek Canan , Gottesman Elizabeth , Moll Henrike 
Published: February 2024

AbstractWhat kind of information is appropriate to teach depends on learner characteristics. In three experiments, 5‐ to 7‐year‐old children (N = 170, 50% female, 68% White; data collection: 2022–2023) chose between basic and complex information to teach an infant or adult audience. The older, but not younger, children, taught more complex information to adults and more basic information to infants, (OR = 2.03). Both ages overcame their own preference for complex information when teaching infants (h = .45). Children's reflections on why they made particular pedagogical choices did not predict audience‐contingent teaching. The findings suggest that young children can infer what kind of information is suitable given a learner's maturity, with a key developmental progression between ages 5 and 7.
Analysing governance‐led infrastructural development nexus in sub‐Saharan Africa: Does the moderating role of institutional quality matter?

Published: February 2024

AbstractGovernments engage in infrastructural developments across the globe, and the level of success often colligates with institutional quality levels. However, despite the presence of governance, the lack of well‐developed infrastructure has bedevilled sub‐Saharan African (SSA) countries for decades. Therefore, this study investigates the governance‐led infrastructural development hypothesis for the SSA region from an institutional quality perspective towards addressing the infrastructural deficit challenges of the region. A combination of advanced panel econometric techniques was applied to data collected from the African Development Bank, World Bank World Development Indicator, and International Monetary Fund (IMF) to investigate the governance‐led infrastructural development hypothesis in SSA while controlling for financial development, economic growth, and industrialization in the region. The findings show that the interaction of institutional quality measures and governance indicators significantly and positively induces infrastructure in sub‐Saharan Africa (SSA). Additionally, while economic growth and financial development yield no expected significant influence on infrastructural developments, industrialization plays a crucial role, as its spillover effects are not confined to boosting economic growth alone but also to infrastructural transformations. Thus, the provision of policy frameworks by authorities to strengthen institutions and promote good governance is vital for articulating and facilitating infrastructural development plans for SSA.

AbstractAimThere are few data regarding the safety and effectiveness of severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2) vaccines in patients with intractable hepatobiliary diseases. We conducted a multicenter, questionnaire‐based, cross‐sectional study to determine the safety and effectiveness of the SARS‐CoV‐2 vaccines in Japanese patients with intractable hepatobiliary disease.MethodsPatients aged ≥18 years with autoimmune hepatitis (AIH), primary biliary cholangitis, primary sclerosing cholangitis, Budd–Chiari syndrome, idiopathic portal hypertension, and extrahepatic portal vein obstruction at each center were consecutively invited to join the study. Participants were asked to complete a questionnaire regarding their characteristics, vaccination status, post‐vaccination adverse effects, and SARS‐CoV‐2 infection. Additionally, liver disease status, treatment regimens, and liver function test values pre‐ and post‐vaccination were collected.ResultsThe survey was conducted from September 2021 to May 2022, and 528 patients (220 AIH, 251 primary biliary cholangitis, 6 AIH– primary biliary cholangitis/primary sclerosing cholangitis overlap, 39 primary sclerosing cholangitis, 4 Budd–Chiari syndrome, 5 idiopathic portal hypertension, and 3 extrahepatic portal vein obstruction) participated in the study. Post‐vaccination adverse effects were comparable to those observed in the general population. Post‐vaccination liver injuries classified as grade 1 or higher were observed in 83 cases (16%), whereas grades 2 and 3 were observed in only six cases (1.1%); AIH‐like liver injury requiring treatment was not observed. Overall, 12 patients (2.3%) were infected with SARS‐CoV‐2, and only one patient was infected 6 months after the second vaccination.ConclusionSARS‐CoV‐2 vaccines demonstrated satisfactory safety and effectiveness in Japanese patients with intractable hepatobiliary diseases.

Published: February 2024

AbstractBackgroundEstrogen receptor (ER)‐positive (ER+) breast cancer accounts for approximately 75% of all breast cancers. Tamoxifen, a selective estrogen receptor modulator, is the standard adjuvant treatment. Although better tolerated than aromatase inhibitors, tamoxifen increases the risk of venous thromboembolism (VTE) 1.4‐fold.AimTo assess the hemostatic imbalance induced by tamoxifen in adjuvant treatment of ER+ breast cancer.MethodTwenty‐five patients in remission from ER+ breast cancer under tamoxifen were included. One hundred and thirty one age‐ and BMI‐matched healthy controls were included to establish reference ranges of thrombin generation assay (TGA) parameters. TGA was performed in the absence and presence of exogenous activated protein C (APC) to calculate the normalized APC sensitivity ratio (nAPCsr), a marker of APC resistance.ResultsAll TG parameters except the endogenous thrombin potential (ETP) (−APC) were significantly impacted by tamoxifen (p < 0.001). In absence of APC, regardless of TGA parameters, at least 50% of results were outside the reference ranges except for ETP, which was above the upper reference limit in only two individuals. The most impacted parameter was the Peak Height with 52% (−APC) and 80% (+APC) of results above the upper reference range limit, respectively. The nAPCsr was significantly higher in tamoxifen users (mean ± standard deviation = 3.18 ± 0.91) compared to the control group (2.19 ± 0.92, p < 0.0001).ConclusionThis observational study showed that patients in remission from ER+ breast cancer taking tamoxifen had altered thrombin generation, as well as an acquired APC resistance. Moreover, this is the first study using the validated ETP‐based APC resistance assay in tamoxifen‐treated patients.

AbstractBackgroundInfective endocarditis (IE) has high morbidity and mortality and is often attributed to dental procedures.AimThis study characterized variables related to paediatric IE in a paediatric hospital cohort.DesignA retrospective review of medical records, from January 1, 2008, to January 1, 2020, to examine demographic, medical and dental history, and risk factors associated with children diagnosed with IE at Nationwide Children's Hospital.ResultsOf the 242 patients who were admitted with tentative IE diagnoses, 67 met the inclusion criteria: 46 (69%) had underlying cardiac conditions and 21 (31%) had not. One‐third had an infection with S. aureus and viridans streptococci. Age was significantly associated with intracardiac devices in children with IE. Mean hospitalization was 25 days, and the mortality was 6 (9%); 41(61%) required surgery for causative defects, and 24 (32%) had dental consultation during admission.ConclusionAlthough cardiac‐related conditions were present in most cases, IE occurred in patients without cardiac factors.

AbstractManagement of pressure sores can have various environmental effects; moreover, the COVID‐19 pandemic notably affected efforts towards effective management of pressure sores. Some cases of COVID‐19 infections require long‐term hospitalization in the intensive care unit. Moreover, special protective equipment worn by physicians owing to the pandemic complicate wound management. In this study, we compared the pressure ulcer characteristics between isolated patients with and those without COVID‐19 and evaluated the effects of isolation on pressure sores. From November 2022 to February 2023, patients who had pressure sores were included and their medical records were reviewed retrospectively. The experimental group included patients with confirmed COVID‐19 infections, who received clinical treatment in an isolated unit. Wound characteristics in each group and associated risk factors were analysed. Fifty‐four isolated patients with COVID‐19 and 58 control patients were included. The Braden Scale score and Korea patient classification system‐1 did not vary significantly between the two groups. However, the number of Grade I pressure sores in the COVID‐19 isolation group was significantly lower than those in the control group (p < 0.001), while the number of lesions was significantly higher (p = 0.034). The mortality rate in the COVID‐19 isolation group was higher than that in the control group (p = 0.008), and more patients were discharged with unhealed wounds (p = 0.004). A higher treatment effect on pressure sores may be expected if the disease is more actively managed. Moreover, the wound care systems for isolated patients with COVID‐19 require further attention.
Epistemologies and Aesthetics of Curriculum, Pedagogical Praxis and Assessment in the Visual Arts: A Comparative Analysis of the International Baccalaureate Diploma Programme and the New South Wales Stage 6 Visual Arts Syllabus
Authors: Blaikie Fiona , Maras Karen 
Published: February 2024

AbstractWe compare epistemologies and aesthetics in the International Baccalaureate Diploma Programme and the Australian New South Wales Stage 6 Visual Arts Syllabus, focusing on curriculum content, pedagogical praxis, and assessment strategies. Both curricula feature making, reflexivity, and critique. International Baccalaureate components are Exhibition, the Process Portfolio, and the Comparative Study. In New South Wales Visual Arts they are the Body of Work and Visual Diary. Issues are the teacher as curriculum; uneven resources; shifting contexts and formulating standardized expectations. In both, qualitative assessment and examination are achieved via articulating criteria and levels of achievement, and examiner training. In International Baccalaureate, what counts as good work can vary in relation to Principal Examiner standards, particularities of context, pedagogy, and resources, with work ranging from sophisticated installations, to anime, to the school art style. In New South Wales Visual Art aesthetic conventions are reinforced because the system is less distributed than International Baccalaureate, where aesthetics become engrained, perpetuating conventions around what counts as good art. In spite of supervening assessment structures, teaching, learning, and assessment in visual arts education is always highly qualitative, unfolding, and rooted in the situated shifting conditions and ways of being in the world of each teacher, student, artwork, examiner, artist, and scholar.

Published: February 2024

AbstractThere have been no reported cases of neuroendocrine carcinoma (NEC) of the cervix with pagetoid spread (Pag‐S). A 44‐year‐old woman came to our department because of abnormal cytology that persisted immediately after a radical hysterectomy for NEC of the cervix. A mapping biopsy in a large area from the vaginal wall to the vulva revealed that synaptophysin/Ki‐67‐positive tumor cells were scattered within the epithelium in multiple areas, suggesting a wide Pag‐S of NEC. Because tumor cells were found beyond the vaginal wall, the anterior pelvic exenteration was performed. Since we could pathologically confirm the complete resection and no distant metastases were detected, no adjuvant therapy was performed. Four years have passed since the initial treatment without any tumor recurrence. It is known that the prognosis of NEC of the cervix that invades beyond the cervix is poor; however, if there is a Pag‐S pattern, a radical surgical treatment can be considered.
Boreal ecopoetics: Christian Dotremont's site‐specific writing in Sápmi
Authors: Sjöberg Sami 
Published: February 2024

AbstractNorthern Fennoscandia entered Christian Dotremont's (1922–1979) imagination in 1956. The Belgian avant‐gardist was comfortable in Central‐European artistic milieus through his involvement in CoBrA (1948–1951), but a total of 12 journeys to Sápmi between 1956 and 1978 had a profound effect on his creative work, especially the logograms he is best known for. This article studies Dotremont's travel writings and logograms as site‐specific forms of writing, which can be seen as precursors to ecopoetic approaches. Dotremont's journeys took place at a cultural turning point, when ethnographers had made their field trips but mass tourism was still in its embryonic state in Sápmi. His Sápmi‐inspired travel writings reveal how the idealism related to a hyperborean north initially intrigued him while he sought to elude modernity. Dotremont's cultural exchanges in Sápmi were non‐artistic but manifested in his art and writing. Sápmi brought about an ecological awakening through awe that was not sublimated but a lived experience. Dotremont immersed himself in Sápmi, with fundamental repercussions to his creative exploits.
Elevated evolutionary rates of biting biomechanics reveal patterns of extraordinary craniodental adaptations in some herbivorous dinosaurs
Authors: Kunz Callum , Sakamoto Manabu 
Published: February 2024

AbstractAdaptation to specialist ecological niches is a key innovation that has contributed to the evolutionary success of many vertebrate clades, underpinning the acquisition of diverse skull morphologies. Dinosaurs, which dominated Mesozoic terrestrial faunas, acquired herbivory multiple times, and evolution of these herbivorous adaptations is linked to drastic changes in dental and craniomandibular functional morphology, yet whether changes in functionally relevant phenotypic traits occurred more rapidly in herbivorous lineages compared to in carnivorous lineages remains largely untested in a statistical phylogenetic framework. Here, we infer rates of phenotypic evolution using phylogenetic variable‐rate models on relative biting edge (tooth row) lengths of 107 dinosaur taxa to test the hypothesis that the acquisition of herbivory is associated with rapid changes in mandibular biomechanics. We find elevated rates of biomechanical evolution in theropods with foreshortened and beaked skulls (Oviraptorosauria, Limusaurus), as well as in ceratopsians and Diplodocus. The presence and position of a reduced tooth row and increased jaw efficiency unite these high‐rate lineages, indicating selection for greater efficiency in biting biomechanics. Large departures from the isometric scaling of these mandibular characteristics helps explain the differences in evolutionary rates in these clades and those of other herbivorous theropods (Therizinosauria, Ornithomimosauria). Additionally, we hypothesize that extreme ontogenetic changes within species lifetimes may be behind some instances of branch‐wise elevated rates. Thus, we show how exceptional rates of biomechanical evolution can reveal signatures of ecological adaptations within dinosaur lineages as well as within‐species ontogenetic sequences.
