Published: October 2024

This study investigates the mediating role of work engagement on the effect of relational job crafting on task performance among employees in the public sector of Ghana. Relational job crafting involves offers significant benefits to public sector employees by enhancing their performance through collaborative engagement. Thus, when employees actively adjust their social work environment, they can reduce (increase) work-related stress (sense of purpose) through fostering stronger relationships, which also improve well-being and performance. The research employed a closed-ended questionnaire and conducted a cross-sectional online survey. The study’s target population consists of 17,163 public sector employees in Cape Coast Metropolis, out of which 456 were randomly selected to complete the survey. The sample size was estimated using the Adam, (2020) approach for selecting samples in a quantitative study. Data collection took place from January to June 2023, and the analysis was conducted utilising the R version of partial least squares structural equation modelling (PLS-SEM). The study revealed an average yet statistically significant influence of relational job crafting on both work engagement and task performance. Thus, relational job crafting had a significant positive effect on work engagement (β = 0.502, p < 0.01) and task performance (β = 0.293, p < 0.01), with work engagement further affecting task performance significantly (β = 0.475, p < 0.01). The significant positive relationship shows that the increase in both relational job crafting and work engagement among Ghanaian public sector employees further improves their performance in the various tasks assigned to them. Also, despite the direct relationship between work engagement and relational job crafting and task performance, it was further revealed that the latter further mediate the relationship among the former and task performance. Thus, it was found that work engagement serves as a complementary partial mediator in the relationship between relational job crafting and task performance (β = 0.238, SE = 0.034, 95% CI = 0.177, 0.309). These findings support the initial hypotheses established for the study. In terms of policy recommendations, this study emphasises the importance of fostering both work engagement and relational crafting to enhance task performance in the Ghanaian public sector. It suggests that employers, including government bodies, directors, and chief executive officers of public institutions, as well as policymakers, including labour unions, should implement measures across various sectors of public services to strengthen employee relations and increase engagement, ultimately enhancing task performance

Published: October 2024

A importância das micro e pequenas empresas (MPE) pode ser notada pela relevante geração de riquezas e de empregos no Brasil. Contudo, os índices de insucesso e mortalidade para esse gênero de empresas são muito elevados e têm como um dos principais causadores a dificuldade no gerenciamento do capital de giro. A realização deste estudo teve como objetivo identificar e discutir os principais fatores, no âmbito da gestão de capital de giro, que prejudicam a continuidade das atividades das MPE industriais. A pesquisa envolveu uma coleta de dados com gestores 55 MPE industriais. Os resultados da pesquisa apontaram sete fatores mais importantes que interferem negativamente na gestão de capital de giro: formação inadequada dos gestores, acúmulo de atividade dos gestores, falta de planejamento financeiro, ausência de acompanhamento de indicadores de gestão, deficiência na gestão de estoque e produção, falta de condições de negociação com os fornecedores e restrições financeiras. Os resultados alcançados podem contribuir com a comunidade acadêmica e empresarial para ampliar a compreensão do que prejudica e dificulta a gestão de MPE, especialmente as que possuem atividade fabril.
On the Origin of the Ancient, Large-scale Cold Front in the Perseus Cluster of Galaxies

Published: October 2024

Abstract
The intracluster medium of the Perseus Cluster exhibits spiral-shaped X-ray surface brightness discontinuities known as “cold fronts,” which simulations indicate are caused by the sloshing motion of the gas after the passage of a subcluster. Recent observations of Perseus have shown that these fronts extend to large radii. In this work, we present simulations of the formation of sloshing cold fronts in Perseus using the AREPO magnetohydrodynamics code, to produce a plausible scenario for the formation of the large front at a radius of 700 kpc. Our simulations explore a range of subcluster masses and impact parameters. We find that low-mass subclusters cannot generate a cold front that can propagate to such a large radius, and that small impact parameters create too much turbulence, which leads to the disruption of the cold front before it reaches such a large distance. Subclusters that make only one core passage produce a stable initial front that expands to large radii, but without a second core passage of the subcluster, other fronts are not created at a later time in the core region. We find a small range of simulations with subclusters with mass ratios of R ∼ 1:5 and an initial impact parameter of θ ∼ 20°–25° that not only produce the large cold front but a second set in the core region at later times. These simulations indicate that the “ancient” cold front is ∼6–8.5 Gyr old. For the simulations providing the closest match with observations, the subcluster has completely merged into the main cluster.
Halo Bias in the Peak Model: A First-principles Nonparametric Approach
Authors: Salvador-Solé Eduard , Manrique Alberto 
Published: October 2024

Abstract
The Press–Schechter (PS) and excursion set (ES) models of structure formation fail in reproducing the halo bias found in simulations, while the ES-peaks' formalism built in the peak model reproduces it only at high masses and does not address in a fully satisfactory manner peak nesting, and the mass and time of ellipsoidal collapse of triaxial peaks in the Gaussian-smoothed density field. Here, we apply the confluent system of peak trajectories formalism fixing all these issues from first principles and with no free parameters to infer the Lagrangian local peak bias parameters, which adopt very simple analytic expressions similar to those found in the PS and ES models. The predicted Eulerian linear halo bias recovers the results of simulations. More specifically, we show that the only small departure observed at intermediate and low masses can be due to the spurious halo splitting and grouping caused by the spherical overdensity halo-finding algorithm used in simulations.
Galaxy–Absorber Association in the Epoch of Reionization: Galactic Population Luminosity Distribution for Different Absorbers at 10 ≥ z ≥ 5.5

Published: October 2024

Abstract
How do galaxies of different luminosities contribute to the metal absorber populations of varying species and strength? We present our analysis of the predicted metal contributions from galaxies as observed in quasar absorption line spectra during the end of the epoch of reionization (10 ≥ z ≥ 5.5). This was done by implementing on-the-fly particle tracking into the latest Technicolor Dawn simulation and then linking C ii, C iv, Si ii, Si iv, O i, and Mg ii absorbers to host galaxies in postprocessing. We define the host galaxy luminosity distribution (HGLD) as the rest-frame ultraviolet luminosity distribution of galaxies contributing ions to an absorber, weighted by the fractional contribution, and compute its dependence on ion and absorber strength. The HGLD shape is predicted to be indistinguishable from the field luminosity function, indicating that there is no relationship between the absorber strength or ion and the luminosity of the dominant contributing galaxy. Switching from galaxy luminosity to stellar mass, the predicted host galaxy mass distributions (HGMDs) indicate that more-massive galaxies contribute a higher fraction of metal ions to absorbers of each species, with the HGMDs of stronger absorbers extending out to higher masses. We conclude that the fraction of absorbing metal ions contributed by galaxies increases weakly with stellar mass, but the scatter in luminosity at fixed stellar mass obscures this relationship. For the same reason, we predict that observational analyses of the absorber–galaxy relationship will uncover stronger trends with stellar mass than with luminosity.

Published: October 2024

Abstract

Rationale:
Mesiodens are supernumerary teeth located in the pre-maxilla between the two central incisors with a prevalence rate of 0.15–1.9%. An impacted mesiodens may cause delayed eruption of permanent incisors, ectopic eruption, pathological disturbances and malalignment of teeth.

Patient Concerns:
The patient complained of missing upper front teeth associated with pain in the same region for two weeks.

Diagnosis:
Upon clinical and radiographic examination, it was diagnosed as triple impacted mesiodens with impacted permanent maxillary central incisors.

Treatment:
The clinicians in the study approached the issue by surgical removal of the impacted mesiodens and orthodontic treatment for extrusion of the impacted permanent maxillary central incisors.

Outcomes:
The patient was relieved of the pre-operative concerns and followed up regularly for the eruption of permanent maxillary central incisors.

Take-away Lessons:
The authors advocate the importance of timely diagnosis and proper management of such rare pathologies.

Published: October 2024

Aim:
This study aims to evaluate the surface homogeneity of poly methyl methacrylate (PMMA) resin fabricated by two different methods of incorporating titanium dioxide nanoparticles (NPs).

Settings and Design:

In vitro study; qualitative analysis.

Materials and Methods:
PMMA resin was divided into two groups with 1% of titanium dioxide NPs were added to each group; Group A contained NPs incorporated in the polymer through magnetic stirring for 60 min and Group B contained NPs incorporated in the monomer through ultrasonic dispersion for 60 min. Ten acrylic block samples were fabricated by standard method for each group and then tested for surface homogeneity by scanning electron microscopy analysis for qualitative analysis.

Results:
Group A showed NPs as defined pale white dots with a consistent distribution pattern and minimal air entrapment. Group B showed NPs agglomerated forming clusters of white dots with flaky sheet-like structures.

Conclusion:
Magnetic stirring of NPs into polymer showed better surface homogeneity than the ultrasonic dispersion of NPs in monomer. The NP incorporation method plays a role in modifying the surface homogeneity of the acrylic.
Optimal execution of logical Hadamard with low‐space overhead in rotated surface code

Published: October 2024

AbstractFault‐tolerant quantum computation requires error‐correcting codes that enable reliable universal quantum operations. This study introduces a novel approach that executes the logical Hadamard with low‐space requirements while preserving the original definition of logical operators within the framework of the rotated surface codes. Our method leverages a boundary deformation method to rotate the logical qubit transformed by transversal Hadamard. Following this, the original encoding of the logical qubit is reinstated through logical flip‐and‐shift operations. The estimated space–time cost for a logical Hadamard operation with a code distance d is 5d2 + 3d2. The efficiency enhancement of the proposed method is approximately four times greater than those of previous approaches, regardless of the code distance. Unlike the traditional method, implementing a logical Hadamard requires only two patches instead of seven. Furthermore, the proposed method ensures the parallelism of quantum circuits by preventing interferences between adjacent logical data qubits.

ABSTRACT
Background Despite national attention on resident well-being, challenges persist. Effective solutions require greater understanding of personal and program factors.
Objective To explore burnout, resilience, self-reported mental health, and perceptions of the learning environment in a national sample of obstetrics and gynecology (OB/GYN) residents.
Methods An observational cross-sectional survey of OB/GYN residents taking the January 2022 national in-training examination included an abbreviated 2-item Maslach Burnout Inventory, a short version of the Connor-Davidson Resilience Scale, and subjective experience of other factors. Kruskal-Wallis and chi-square tests explored differences in outcomes and associations between variables.
Results Among 5761 residents taking the examination, 3741 (64.9%) participated, with 2425 of 3741 (64.8%) reporting burnout, 2138 (57.2%) depression, 2651 (70.9%) anxiety, and 147 (3.9%) suicidal ideation. Women fared worse than men in terms of burnout (2105 of 3147, 66.9% vs 281 of 496, 56.7%, P&lt;.001), depression (1843 of 3147, 58.6% vs 256 of 496, 51.6%, P=.004), anxiety (2318 of 3147, 73.7% vs 294 of 496, 59.3%, P&lt;.001), and resilience (5.9±2.1 vs 6.2±2.1, P=.006). More nonbinary residents considered leaving residency (17 of 49, 34.7% vs 676 of 3147, 21.5% [women] and 108 of 496, 21.8% [men], P=.008). Race-based differences were seen in depression, suicidal ideation, and thoughts of leaving residency. Increased binge drinking was reported with increasing postgraduate year. Among 614 residents reporting that well-being was not a priority in their program, 539 of 614 (87.8%) reported burnout, 469 of 614 (76.4%) depression, and 508 of 614 (82.7%) anxiety.
Conclusions Residents report high rates of mental health concerns, and these are worse among women, gender nonconforming individuals, Black residents, and those who perceive well-being is not a priority in their training program.

Published: October 2024

ABSTRACT
Background A drawback to interviews having largely become virtual is candidates’ difficulty sensing a program’s fit. Programs have offered nonevaluative second looks to address this. There is concern that in-person contact with candidates would still indirectly contribute to a candidate’s evaluation.
Objective We describe implementing an alternative interview structure to incorporate the benefits of virtual and in-person interviews, and describe preliminary feasibility and acceptability data.
Methods Our general surgery program selection process for the 2022-2023 application cycle included a first phase of holistic review and a second phase of interviews. The second phase had a first round of virtual interviews, then a second round of in-person interviews (with a virtual option). Only scores from the second interview were used in ranking. Prior to the Match, applicants and faculty were surveyed about the process.
Results All 1175 applications to the program were reviewed. Of those, 190 (16.2%) were invited to interview virtually; 188 of 190 (98.9%) completed the virtual interview. Eighty-two of 188 (43.6%) were invited for a second interview; 69 of 82 (84.1%) chose to interview in-person, and 13 of 82 (15.9%) interviewed virtually. Sixty-eight of 188 (36.2%) applicants responded to the survey. Sixty-three of 68 (92.6%) agreed the 2-stage interview process was fair, and 51 of 68 (75%) felt that nonevaluative second looks were not truly nonevaluative. Fifteen faculty spent 3 hours over 6 weeks in holistic review. Twenty-four faculty completed 6 days of interviews, each spending 2.5 to 3 hours per day. Twelve of 24 faculty (50%) responded to their survey, with all 12 stating they would participate again.
Conclusions A process of first-round virtual and second-round in-person interviews was feasible and perceived by applicants to be fair and beneficial.

Published: October 2024

A busca por materiais de construção sustentáveis é uma discussão global, e a madeira surge como uma opção viável ao aço e ao concreto devido à sua natureza renovável. A madeira pode ser transformada em "madeira engenheirada" por meio de processos físico-químicos, tornando-a capaz de substituir materiais convencionais na construção. O MDP (Medium Density Particleboard) é um compósito de madeira engenheirada utilizado na indústria moveleira, tendo sua aplicação na construção civil pouco explorada. Este trabalho tem por objetivo avaliar o desempenho acústico de um escritório de planta livre com elementos de vedações em MDP utilizando os parâmetros acústicos objetivos da norma ISO 3382-3:2022. A pesquisa também apresenta a avaliação do isolamento acústico entre salas de reunião separadas por uma vedação vertical inovadora de painéis em MDP estruturados por perfis de aço cujas medições ocorreram por meio das normas ABNT NBR ISO 3382-2:2017 e ABNT NBR ISO 16283-1:2018. As medições foram realizadas no escritório do Cilla Tech Park, localizado na cidade de Guarapuava-PR e os resultados indicam que os ambientes possuem boas qualidades acústicas conforme as normativas vigentes.

Análise de sensibilidade do projeto de norma ABNT – simulação de transporte de umidade
Authors: Bernardes Luiza Coutinho , Cunha Eduardo Grala da , Brito Adriana Camargo de , Mendes Nathan 
Published: October 2024

Esta pesquisa tem por objetivo analisar o projeto de norma ABNT “Simulação Computacional do Comportamento Higrotérmico de Paredes – Procedimento” quanto à sensibilidade às variações das condições de contorno de produção de umidade, uso e ocupação. O método da pesquisa consiste em aplicar as condições propostas no projeto de norma e analisar a sensibilidade às variações das condições de contorno de produção de umidade, ocupação, ventilação e chuva dirigida, por meio de simulações de desempenho higrotérmico. O projeto de norma utiliza valores de ganhos internos que foram baseados na NBR 15575, os quais se apresentam como subestimados para uma análise mais crítica considerando a alta ocupação das habitações no Brasil. Outro quesito é a abertura das janelas considerando um valor de referência pré-definido, o qual se mostrou inadequado para as análises, visto que não são consideradas condições mais críticas nem próximas da realidade de uma habitação. Em relação à chuva dirigida, os resultados mostraram a grande importância de se considerar na norma o efeito da precipitação no comportamento higrotérmico dos ambientes, especialmente por não constar em outros documentos técnicos. As variáveis mais sensíveis que influenciaram o desempenho higrotérmico da edificação foram a ocupação interna e a chuva dirigida, no entanto cada critério de análise apresentou uma variável mais influente, não podendo concluir que apenas uma variável é mais influente no desempenho higrotérmico total da edificação.

A construção civil é responsável por promover grandes benefícios para sociedade como viabilizar à população de baixa renda o acesso à moradia adequada e regular. Contudo, este mesmo setor é afetado pela deficiência nas suas técnicas de planejamento. Para isso, o uso de novas ferramentas vêm sendo propostas para modificar o estado atual deste setor, como a Modelagem da Informação da Construção – BIM. Esta pesquisa buscou a elaboração de um framework e sua validação com a adoção do BIM como ferramenta de apoio no planejamento 4D em um estudo de caso de uma habitação de interesse social, apontando os benefícios do uso do BIM 4D com a adoção de ferramentas BIM para apoiar o planejamento. Para atingir os objetivos foi necessário dividir em quatro fases distintas: (1) revisão da literatura sobre os principais conceitos e aplicações do uso BIM 4D para o planejamento (2) elaboração de um framework para apoio no planejamento e simulação 4D, (3) preparação dos modelos disciplinares para a simulação 4D e a elaboração do cronograma, e a (4) execução do framework a e a sua validação no estudo de caso. Como resultado, verificou-se que o framework no planejamento com o BIM 4D pode ser aplicado às fases de pré-construção com a realização da simulação de projeto e, na fase de execução pode oferecer uma visualização do progresso do projeto por meio da comparação entre o cenário real e o cenário planejado através da simulação 4D. Dentre os principais benefícios percebidos neste estudo através do uso de modelos BIM 4D como ferramenta de apoio no planejamento, foi a possibilidade de visualização detalhada que atua como uma solução inovadora para superar as deficiências das práticas atuais de planejamento e controle de obras.
