The Decline of Substance over Form in Accounting: A Problematic Dichotomy
Authors: Williams Paul F. 
Published: May 2022

Abstract
This essay is a comment on the paper authored by Fischer, Ellman and Schocet (2021, The decline of substance over form in accounting. Accounting, economics, and law: A convivium. (2023)) who argue that the trend in financial reporting regulation involves de-emphasizing the important of economic substance relative to form in how auditors are to perceive their role. The danger foreseen by the authors is the further shrinking of the leeway for professional judgment, which is an important hallmark of a true professional. Agreeing the authors have raised a crucial issue for any group claiming professional status, I try to add to the discussion by pointing out that form and substance in the realm of financial reporting regulation are not antipodes but complementary parts of a process of continuous redefining of what economic substance is. Social reality is socially constructed and as such choices of form made by humans effectively shape substance. Given the capture of accounting by economics during the 1960s, accountants have lost an appreciation for the tentativeness of economic substance and now serve not as participants in shaping economic substance but as enforcers of an imaginary economic substance that derives from the assumptions and values in the ideology of neoclassical economics.
Umbilical artery aneurysm without aneuploidy and delivery of a live neonate
Authors: Lewis Gregory K. , Dawkins Josette C. , Tang Xiangna 
Published: May 2022

Abstract

Objectives
Umbilical artery aneurysm, a rare structural anomaly of the umbilical cord, is frequently associated with fetal aneuploidy, fetal growth restriction and fetal demise. At present there are no definitive protocols or guidelines for the surveillance and management of this condition.

Case presentation
The index case is an 18-year-old primigravida who had an ultrasound at 35 weeks and 5 days gestation due to lagging symphysio-fundal height measurement. The ultrasound scan revealed a normal fetus with estimated fetal weight that was appropriate for gestational age. There was a cystic structure with internal echoes originating from the placenta at the point of the umbilical cord insertion, which was determined to be a 1.9 × 1.8 cm umbilical artery aneurysm on 3D and Doppler imaging. On follow up imaging the aneurysm had increased in size and measured 3.06 × 1.79 cm. The patient subsequently had a cesarean section delivery of a live female. Karyotyping subsequently revealed 46 XX.

Conclusions
A total of 15 cases of umbilical artery aneurysm have been reported in the literature to date, of which there were 5 live born infants with normal karyotype. The remaining 10 cases were intra-uterine fetal demise or trisomy 18 with subsequent neonatal deaths. When monitoring the aneurysms with ultrasound, change in size and Doppler indices play a pivotal role in helping to determine time and mode of delivery and thus allow for a favorable perinatal outcome.
Persistence landscapes of affine fractals
Authors: Catanzaro Michael J. , Przybylski Lee , Weber Eric S. 
Published: May 2022

Abstract
We develop a method for calculating the persistence landscapes of affine fractals using the parameters of the corresponding transformations. Given an iterated function system of affine transformations that satisfies a certain compatibility condition, we prove that there exists an affine transformation acting on the space of persistence landscapes, which intertwines the action of the iterated function system. This latter affine transformation is a strict contraction and its unique fixed point is the persistence landscape of the affine fractal. We present several examples of the theory as well as confirm the main results through simulations.
Collective Narcissism and Perceptions of the (Il)legitimacy of the 2020 US Election
Authors: Federico Christopher M. , Farhart Christina , Vitriol Joseph , Golec de Zavala Agnieszka 
Published: May 2022

Abstract
Recent work suggests that collective narcissism—an exaggerated, unrealistic belief in an in-group’s greatness that demands constant external validation—is a reliable predictor of authoritarian-populist hostility toward democratic norms, processes, and outcomes. In the present study, we use a recent survey of American adults to examine the relationship between collective narcissism and perceptions that the 2020 election in the US was illegitimate. We find evidence that those high in national collective narcissism are more likely to endorse a number of beliefs about the illegitimacy of the 2020 US election, including greater perception of fraud, procedural unfairness, and inaccurate vote counting. Importantly, we find that this relationship is strongest among those whose identities were most threatened by a loss of power due to the 2020 presidential outcome, i.e., Republicans and conservative identifiers.

Published: May 2022

Abstract

Objectives
Stillbirth remains a global public health issue; in low-resource settings stillbirth rates remain high (>12 per 1,000 births target of Every Newborn Action Plan). Preeclampsia is major risk factor for stillbirths. This study aimed to determine the prevalence and risk factors for stillbirth amongst women with severe preeclampsia at Mpilo Central Hospital.

Methods
A retrospective cross-sectional study was conducted of women with severe preeclampsia from 01/01/2016 to 31/12/2018 at Mpilo Central Hospital, Bulawayo, Zimbabwe. Multivariable logistic regression was used to determine risk factors that were independently associated with stillbirths.

Results
Of 469 women that met the inclusion criteria, 46 had a stillbirth giving a stillbirth prevalence of 9.8%. The risk factors for stillbirths in women with severe preeclampsia were: unbooked status (adjusted odds ratio (aOR) 3.01, 95% (confidence interval) CI 2.20–9.10), frontal headaches (aOR 2.33, 95% CI 0.14–5.78), vaginal bleeding with abdominal pain (aOR 4.71, 95% CI 1.12–19.94), diastolic blood pressure ≥150 mmHg (aOR 15.04, 95% CI 1.78–126.79), platelet count 0–49 × 109/L (aOR 2.80, 95% CI 1.26–6.21), platelet count 50–99 × 109/L (aOR 2.48, 95% CI 0.99–6.18), antepartum haemorrhage (aOR 12.71, 95% CI 4.15–38.96), haemolysis elevated liver enzymes syndrome (HELLP) (aOR 6.02, 95% CI 2.22–16.33) and fetal sex (aOR 2.75, 95% CI 1.37–5.53).

Conclusions
Women with severe preeclampsia are at significantly increased risk of stillbirth. This study has identified risk factors for stillbirth in this high-risk population; which we hope could be used by clinicians to reduce the burden of stillbirths in women with severe preeclampsia.
Evaluating the Growth Assessment Protocol for stillbirth prevention: progress and challenges
Authors: Butler Emily , Hugh Oliver , Gardosi Jason 
Published: May 2022

Abstract
Many stillbirths are associated with fetal growth restriction, and are hence potentially avoidable. The Growth Assessment Protocol (GAP) is a multidisciplinary program with an evidence based care pathway, training in risk assessment, fetal growth surveillance with customised charts and rolling audit. Antenatal detection of small for gestational age (SGA) has become an indicator of quality of care. Evaluation is essential to understand the impact of such a prevention program. Randomised trials will not be effective if they cannot ensure proper implementation before assessment. Observational studies have allowed realistic evaluation in practice, with other factors excluded that may have influenced the outcome. An award winning 10 year study of stillbirth data in England has been able to assess the effect of GAP in isolation, and found a strong, causal association with improved antenatal detection of SGA babies, and the sustained decline in national stillbirth rates. The challenge now is to apply this program more widely in low and middle income settings where the main global burden of stillbirth is, and to adapt it to local needs and resources.
Multimodal instructional communication in science and engineering in two university classrooms
Authors: Sharma Bal Krishna 
Published: May 2022

Abstract
Universities in English speaking countries have been witnessing an increasing number of international faculty who speak English as an international language. However, the universities are mostly guided by the dominant monolingual ideologies and language policies that favor verbal repertoires in standard English even though instructional communication is characteristically multimodal. Against this backdrop, this article focuses on two faculty members in STEM and investigates their instructional interaction. Using multimodal interaction as a theoretical and methodological heuristic, the analysis pays attention to how modes, codes and material objects are ensembled in specific configurations as instructors and students engage in the process of meaning negotiation. The instructors’ instructional practices and perspectives demonstrate the importance of the entanglement of language with diverge semiotic, social and material elements of communication. The findings suggest a need for a broader definition and scope of instructional interaction in STEM.
Enhancement of thermal conductivity in polymer composites by maximizing surface-contact area of polymer-filler interface
Authors: Kumar Vijendra , Barnwal Abhishek , Shukla Rajesh K. , Shakya Jyoti 
Published: May 2022

Abstract
In this article we discuss in detail the effective approaches to enhance the thermal conductivity in polymer composites. Numerical simulations show that maximizing interfacial area between filler and polymer enhances very significantly the effective thermal conductivity in composites. We show that among the different geometries thermal conductivity is high for those geometries for which the ratio of surface-area to volume is high. For fillers of a particular geometry, by maximizing its surface area without changing the volume fraction of the metallic filler, the effective thermal conductivity increases. Thus, the interfacial area between filler and polymer plays an important role in the enhancement of thermal conductivity. It is also observed that as this interfacial area increases, increase in effective thermal conductivity follows from linear to the logarithmic growth. It should be noted that to inherit the polymer properties there is a restriction on the upper bound of volume fraction of the fillers. The current study brings out an important step in this direction. Our results are technologically very important in designing composite polymers for better heat conduction and are very cost-effective. This study also provides a connection between the bulk and the surface area in effective determination of the thermal conductivity.
Metal-mediated C–C bond formation in a platinum(II)-coordinated dipyridylmethane ligand: an unusual example of “ipso-coupling” with solvent involvement
Authors: Sommerfeld Nadine S. , Gülzow Jana , Kohl Julia , Grohmann Andreas 
Published: May 2022

Abstract
We report the chelation-assisted oxidative CH2 extrusion from a PtII-coordinated dipyridylmethane, resulting in the formation of a 2,2′-bipyridyl ligand. This unusual one-pot reaction (solvent: dimethylformamide, DMF), which is quantitative, proceeds in air at mildly elevated temperature, with CH2 → C=O conversion, decarbonylation, and ipso-ipso C–C coupling of the two pyridyl residues (“fragment coupling”). It constitutes, in effect, a chelate ring contraction by one member.

Authors: Dwi Putra M. Adib Jauhari , Himayati Ade Ima Afifa 
Published: May 2022

AbstractWe studied the Leslie-Gower model of predator-prey with herd behavior. The square root functional response models predator and prey interactions that show herd behavior. This study aims to determine the formulation of the predator-prey model with herd behavior on prey, knowing the fixed points and its stability and simulating the model numerically. We found three fixed points that may exist: the extinction point of both species, the extinction of predator point, and the point of coexistence of the two species. The extinction of predator points is always unstable, while the point of coexistence of the two species can be stable under certain conditions. Due to the presence of square roots, the behavior of the solutions near the extinction point of the two species is not readily apparent. Numeric simulation shows that changing the initial condition and parameters can change the system's stability.Keywords: predator-prey; functional response; herd behavior; square root functional response, Leslie-Gower model. AbstrakArtikel membahas model predator prey Leslie-Gower dengan perilaku bergerombol pada prey. Interaksi predator dan prey yang menunjukkan perilaku bergerombol dimodelkan dengan fungsi respon akar kuadrat. Penelitian ini bertujuan untuk mengetahui formulasi model predator-prey dengan perilaku bergerombol pada prey, mengetahui titik ekuilibrium dan kestabilannya serta menyimulasikan model tersebut secara numerik. Hasil menunjukkan terdapat tiga titik tetap yang mungkin eksis, yaitu titik kepunahan kedua spesies, titik kepunahan predator dan titik koeksistensi kedua spesies. Titik kepunahan predator selalu tidak stabil, sedangkan titik koeksistensi kedua spesies bisa stabil dengan syarat tertentu. Karena adanya akar kuadrat, perilaku solusi di dekat titik kepunahan kedua spesies tidak mudah terlihat. Simulasi numerik menunjukkan bahwa perubahan nilai awal dan parameter dapat mengubah kestabilan sistem.Kata Kunci: predator prey; fungsi respons; perilaku bergerombol; fungsi respon akar kuadrat; model Leslie-Gower.

AbstractIn this paper, uncoupled two agents modeling is proposed using an optimal bilinear control approach. The model is proposed using assumptions: an absence of the multi agent leader, each agent cannot control the others, each agent never collides with the others, and each agent has the same properties. The special functional cost consisting of a repellent cost is considered. The Pontryagin Maximum Principle is used to determine the optimal path for each agent. After control and optimal path for each agent are obtained some of the simulation results are exposed in this paper.Keywords: uncoupled agent; modeling; bilinear system.

Introdução: O diagnóstico do hiperparatireoidismo primário (HPTP) melhorou nos últimos anos, identificando-se a forma assintomática com hipercalcemia leve e a normocalcêmica, com níveis normais de cálcio. Objetivo: identificar o perfil epidemiológico e estabelecer a prevalência de doença óssea e litíase renal em pacientes com HPTP atendidos no ambulatório de um centro de atendimento terciário à saúde no estado de São Paulo, Brasil. Métodos: Análise retrospectiva dos prontuários de pacientes atendidos no ambulatório no período de julho de 2015 a junho de 2016 com diagnóstico de HPTP (44 pacientes). Considerando a presença de hipercalcemia, foram caracterizados dois grupos de pacientes: com hipercalcemia (n=36) e com normocalcemia (n=8). Os exames laboratoriais e de imagem foram avaliados. Resultados: O grupo hipercalcêmico mostrou média de idade superior à do normocalcêmico e menor função renal. A diminuição da massa óssea esteve presente em ambos os grupos hipercalcêmico e normocalcêmico com prevalência de 82% e 62,5% e de osteoporose de 57,6% e 37,5%, respectivamente. A litíase renal, analisada por ultrassom renal, foi identificada em 42% e do grupo hipercalcêmico e em 66,6% do grupo normocalcêmico. Conclusão: a osteoporose e a litíase renal são frequentes no HPTP, tanto na forma hipercalcêmica como normocalcêmica. Abordagem adequada dos portadores dessa morbidade pode prevenir complicações ósseas e renais.
