Abstract
Background
Although procrastination has been widely studied in adults, comparatively little work has focused on adolescent procrastination, especially in the Pacific region. As a contribution to knowledge and diversification of population sampling, therefore, we examined procrastination in a multi-ethnic sample of adolescents from New Caledonia. Specifically, we examined gender and ethnic differences in procrastination, as well as sociodemographic and ethnic identity predictors of procrastination.

Methods
927 adolescents (474 boys, 453 girls; age M = 13.2 years) completed measures of procrastination and ethnic identity, and reported their ethnicity (Kanak vs. Polynesian vs. European). Sociodemographic data (sex, age, area of residence and socioeconomic status) were also collected.

Results
An analysis of variance indicated significant ethnic (Kanak and Polynesian adolescents had higher procrastination than European adolescents) and sex differences (girls had higher procrastination than boys), but no significant interaction. Regression analysis showed that higher procrastination was significantly associated with sex, ethnicity, age, and the interaction between ethnicity and ethnic identity. Moderation analysis showed that ethnic identity moderated the relationship between ethnicity and procrastination, but only in Kanak adolescents.

Conclusion
Relatively high levels of procrastination were observed in Kanak and Polynesian adolescents, and in girls. These findings, while preliminary, may have important implications for academic attainment in the New Caledonian context.
3D printing fabrication process for fine control of microneedle shape
Authors: Jeong Jinwoong , Park Jaeu , Lee Sanghoon 
Published: January 2023

AbstractMicroneedle electrode (ME) is used to monitor bioelectrical signals by penetrating via the skin, and it compensates for a limitation of surface electrodes. However, existing fabrication of ME have limited in controlling the shape of microneedles, which is directly relevant to the performance and durability of microneedles as an electrode. In this study, a novel method using 3D printing is developed to control needle bevel angles. By controlling the angle of printing direction, needle bevel angles are changed. Various angles of printing direction (0–90°) are investigated to fabricate moldings, and those moldings are used for microneedle fabrications using biocompatible polyimide (PI). The height implementation rate and aspect ratio are also investigated to optimize PI microneedles. The penetration test of the fabricated microneedles is conducted in porcine skin. The PI microneedle of 1000 μm fabricated by the printing angle of 40° showed the bevel angle of 54.5°, which can penetrate the porcine skin. The result demonstrates that this suggested fabrication can be applied using various polymeric materials to optimize microneedle shape.

Abstract
Purpose
To investigate the feasibility of ultra-low-dose CT (ULDCT) reconstructed with the artificial intelligence iterative reconstruction (AIIR) algorithm in total-body PET/CT imaging.

Methods
The study included both the phantom and clinical parts. An anthropomorphic phantom underwent CT imaging with ULDCT (10mAs) and standard-dose CT (SDCT) (120mAs), respectively. ULDCT was reconstructed with AIIR and hybrid iterative reconstruction (HIR) (expressed as ULDCT-AIIRphantom and ULDCT-HIRphantom), respectively, and SDCT was reconstructed with HIR (SDCT-HIRphantom) as control. In the clinical part, 52 patients with malignant tumors underwent the total-body PET/CT scan. ULDCT with AIIR (ULDCT-AIIR) and HIR (ULDCT-HIR), respectively, was reconstructed for PET attenuation correction, followed by the SDCT reconstructed with HIR (SDCT-HIR) for anatomical location. PET/CT images’ quality was qualitatively assessed by two readers. The CTmean, as well as the CT standard deviation (CTsd), SUVmax, SUVmean, and the SUV standard deviation (SUVsd), was recorded. The signal-to-noise ratio (SNR) and contrast-to-noise ratio (CNR) were calculated and compared.

Results
The image quality of ULDCT-HIRphantom was inferior to the SDCT-HIRphantom, but no significant difference was found between the ULDCT-AIIRphantom and SDCT-HIRphantom. The subjective score of ULDCT-AIIR in the neck, chest and lower limb was equivalent to that of SDCT-HIR. Besides the brain and lower limb, the change rates of CTmean in thyroid, neck muscle, lung, mediastinum, back muscle, liver, lumbar muscle, first lumbar spine and sigmoid colon were −2.15, −1.52, 0.66, 2.97, 0.23, 8.91, 0.06, −4.29 and 8.78%, respectively, while all CTsd of ULDCT-AIIR was lower than that of SDCT-HIR. Except for the brain, the CNR of ULDCT-AIIR was the same as the SDCT-HIR, but the SNR was higher. The change rates of SUVmax, SUVmean and SUVsd were within $$\pm$$
±
3% in all ROIs. For the lesions, the SUVmax, SUVsd and TBR showed no significant difference between PET-AIIR and PET-HIR.

Conclusion
The SDCT-HIR could not be replaced by the ULDCT-AIIR at date, but the AIIR algorithm decreased the image noise and increased the SNR, which can be implemented under special circumstances in PET/CT examination.

Abstract
Background
Hump-nosed vipers (HNV; Hypnale spp) are one of the medically important venomous snakes in Sri Lanka and South-Western regions of India. The haemostatic dysfunction due to HNV bites is poorly characterized by standard diagnostic tests performed to identify coagulopathy. We aimed to determine the usefulness of rotational thromboelastometry (ROTEM) parameters compared to 20-minute whole blood clotting test (WBCT20) and prothrombin time (PT) in understanding the coagulopathy of HNV bites.

Methods
Twenty-three HNV snakebite patients in a prospective study of 127 consecutive snakebites were recruited. After recording details of the clinical presentation, PT/international normalized ratio (INR), WBCT20 and ROTEM delta were performed at presentation.

Results
In this preliminary study, none of the patients had clinically apparent bleeding. Coagulopathy was detected by either WBCT20, INR or ROTEM in 13 HNV patients. Eleven had a coagulopathy detectable by ROTEM (either abnormal EXTEM-CT, INTEM-CT or FIBTEM-MCF) but with negative WBCT20. Of them, only two had prolonged INR values. Two patients had positive WBCT20 but with normal ROTEM and INR values. The remaining 10 patients did not show any coagulopathy either by INR, ROTEM or WBCT20.

Conclusion
In this preliminary study with small number of sample size, ROTEM parameters appeared to be more sensitive to subtle changes in coagulation compared to WBCT20. The clinical utility of detecting these changes and their usefulness in managing snakebite should be explored further in a larger study.

Published: January 2023

AbstractThe Covid-19 pandemic has sparked an unprecedented public debate over socio-scientific controversies, particularly regarding vaccination and social distancing measures. Despite the potential of such subjects for developing critical thinking and a sense of citizenship, the theme of controversies is still incipient in science museums. This documentary study investigates the way three science institutions have proposed online exhibits on Covid-19 on Google Arts & Culture platform and checks their potential for favoring teaching on controversial science topics. Google Arts & Culture platform was searched for Covid-19-related keywords and the filtering of the results was based on focus and organizing institutions. Three exhibits were detected, whose analysis was submitted to an inter-rater agreement (Cohen’s kappa). The results revealed the predominance of social and economic aspects that can strongly favor more scientifically progressive views of both science literacy and a socially undistorted science. On the other hand, the superficiality of political discussions on science topics, a lack of naturalization of the controversial discussions, and an excessive use of textual content were identified, thus revealing some initiatives have not explored the interactivity, multimediality, and the way dilemmas that mark the trajectory of science museums extend to online exhibits. From this perspective, we point out paths for teaching and learning socio-scientific controversies in museums.
Elevated Serum Uric Acid Is Associated With Gestational Diabetes Mellitus: An Observational Cohort Study
Authors: Yue Chaoyan , Ying Chunmei , Li Xiaotian 
Published: January 2023

Abstract

Context
Elevated serum uric acid may be closely related to the occurrence of gestational diabetes mellitus (GDM).

Objective
We aimed to elucidate the relationship between changes in serum uric acid before 24 weeks of gestation and the risk of GDM and associated adverse pregnancy outcomes and provide clinical epidemiological evidence for the involvement of uric acid in the etiology of GDM.

Methods
We conducted a retrospective cohort study of 23 843 singleton pregnant women between February 2018 and June 2022. The exposure factor was serum uric acid before 24 weeks of gestation, primary outcome was gestational diabetes diagnosed at 24 to 28 weeks of gestation, and secondary outcomes were GDM A2 (GDM requiring pharmacotherapy), GDM combined with pre-eclampsia, preterm delivery, and large for gestational age infants. Adjusted risk ratios (RRs) were calculated using multivariate predictive marginal proportions from logistic regression models.

Results
Among 23 843 singleton pregnant women, 3204 (13.44%) were diagnosed with GDM at 24 to 28 weeks of gestation, and elevated uric acid before 24 weeks of gestation was strongly associated with the risk of GDM. Compared with uric acid &lt;240 µmol/L, the RR for GDM was 1.43 (95% CI 1.29-1.56) when uric acid was between 240 and 300 µmol/L; when uric acid was &gt;300 µmol/L, the RR for GDM was 1.82 (95% CI 1.55-2.15). In secondary outcomes uric acid had a similar relationship with GDM A2, preterm birth, and GDM combined with pre-eclampsia.

Conclusion
Elevated uric acid levels before 24 weeks of gestation are associated with subsequent GDM; the best time to test for uric acid is before 18 weeks of gestation. Pregnant women with low and intermediate risk for GDM development may benefit more from serum uric acid measurements before 18 weeks of gestation.
Experimental Choice and Disruptive Technologies
Authors: Gans Joshua S. 
Published: January 2023

This paper examines how a firm’s choice of the type of experiment impacts on its potential exploitation of new technological opportunities. It does so in the context of the failure of successful firms (or disruption) where the literature has informally suggested that firms undertake errors in experimental choice. It is shown that firms will generically choose experiments that minimize false positives (a high-bar) or minimize false negatives (a low-bar) rather than strike a balance between the two. This is done to better inform decisions regarding the exploitation of technological opportunities. It is shown that these choices can differ between incumbents and entrants based on their fundamentals and because of the anticipation of competition between them. This paper was accepted by David Simchi-Levi, business strategy.

Fragmentos Do Discurso Populista: A Dicotomia Amigo-Inimigo Na Retórica Do Governo Jair Bolsonaro | Fragmentos De Un Discurso Populista:La Dicotomía Amigo-Enemigo En La Retórica Del Gobierno Jair Bolsonaro En Brasil
Authors: Jatobá Daniel , Andrade Mateus 
Published: January 2023

O discurso populista é marcado pelo antagonismo entre o povo, de um lado, e a elite política, do outro, sendo o uso de estratégias de comunicação com as massas e a valorização da soberania popular duas das principais características do populismo apontadas pela literatura acadêmica. O artigo apresenta os resultados de uma análise de conteúdo a partir de um corpus extenso de discursos oficiais pronunciados pelo presidente da República do Brasil, Jair Messias Bolsonaro, eleito em 2018, e do seu primeiro chanceler, Ernesto Araújo. Argumenta-se que, no caso estudado, a tradicional oposição povo-elite do discurso populista assume um antagonismo mais amplo baseado na dicotomia amigo-inimigo, que, por sua vez, define o conceito do político na conhecida teorização de Carl Schmitt. Além disso, encontramos evidências de que a retórica adotada pelos dois líderes incorpora essa dicotomia tanto no discurso sobre política interna como no discurso sobre política externa.Palavras-chave: Populismo; Análise de Conteúdo; Governo Jair Bolsonaro.RESUMENEl discurso populista es caracterizado por el antagonismo entre el pueblo, de un lado, y la élite, del otro, siendo el uso de estrategias de comunicación con las masas y la valorización de la soberanía popular dos de los principales rasgos del populismo según la literatura académica.

O objetivo deste trabalho é apresentar uma análise da mobilização de discursos religiosos de perfil populista por Jair Bolsonaro, candidato a presidente da República eleito no ano de 2018. A importância da religião neste contexto político se deve em razão da proximidade do então candidato com a Frente Parlamentar Evangélica (FPE) no Congresso Nacional, servindo para uma campanha exitosa com pautas em defesa da moralidade cristã e o fim da “velha política”. A metodologia do trabalho é qualitativa, visando compreender a relação entre o atual Presidente da República brasileiro e os evangélicos, foi feita uma imersão na literatura acadêmica que trabalha a presença evangélica na política nacional contemporânea. Somado à isso, trabalhamos com autores que dissertam sobre o populismo, além de analisarmos discursos e falas de cunho religioso proferidos principalmente por Jair Bolsonaro (PL) ao longo do ano de 2019, bem como, acenos do mesmo ao segmento por meio de decretos presidenciais. Os resultados corroboram com a premissa de que Bolsonaro se caracteriza como um populista de direita que se utiliza da linguagem religiosa cristã conservadora para anagariar apoio e atacar seus adversários na cena política do Brasil.Palavras-chave: Populismo; Religião; Evangélicos.ABSTRACTThe objective of this paper is to present an analysis of the mobilization of religious discourses of populist profile by Jair Bolsonaro, candidate for president of the Republic elected in 2018.
