Published: September 2024

Abstract

Context
Bone marrow adiposity (BMAT) alterations in patients with type 2 diabetes mellitus (T2DM) may contribute to adverse bone effects.

Objective
Characterization of BMAT content and composition in patients with well-controlled T2DM.

Methods
This cross-sectional study included 2 groups of postmenopausal women: one with T2DM and the other without. The proton density fat fraction (PDFF) of the lumbar spine and proximal femur, comprising the femoral head, neck, and diaphysis, was assessed using chemical shift-based water-fat separation imaging (WFI). Magnetic resonance imaging with spectroscopy (1H-MRS) was performed in a subgroup of participants to confirm the PDFF measurements and determine the apparent lipid unsaturation level (aLUL) at the L3 vertebrae and femoral neck. The association of imaging-based PDFFs and aLUL between diabetes groups was investigated by adjusting for confounding factors using a linear mixed model.

Results
Among 199 participants, patients with T2DM (n = 29) were significantly heavier (P &lt; .001) and had a higher bone mineral density (BMD) (P &lt; .001 for all sites) than nondiabetic patients (n = 170). When PDFFs were compared after adjusting for age, body mass index (BMI), and BMD, the femoral head WFI-based PDFF was lower in patients with T2DM (mean [standard error] 88.0% [0.7] vs 90.6% [0.3], P &lt; .001). Moreover, the aLUL at the L3 vertebrae was lower in patients with T2DM (n = 16) than in without (n = 97) (mean [standard error] 3.9% [0.1] vs 4.3% [0.1], P = .02).

Conclusion
The content and composition of BMAT are modified in postmenopausal women with T2DM and these changes occur at specific sites.

Authors: Agustina Rismia , Fetzer Susan Jane , Lai Wei-Shu , Konlan Kennedy Diema , Romadhon Pradana Zaky , Lin Mei-Feng 
Published: September 2024

Background: In Indonesia, the diagnosis of a serious illness is often mediated through the patient's family, reflecting the cultural importance of family involvement in the patient's care and collective decision-making. Aim: To use a case study to show the difficulty that healthcare professionals face telling the patient the truth about their condition in Indonesia. Method: The Kagawa-Singer and Blackhall ABCDE framework was used during truth-telling dilemmas to assess patients' and families' attitudes (A), beliefs (B), contexts (C), decision-making styles (D) and environments (E). Findings: Studies have shown that family involvement in health-related communications can alleviate the stress associated with the disclosure of a serious illness. Palliative care nurses must acknowledge the importance of family in the patient's cultural context, by involving them in the disclosure of a diagnosis and disease trajectory by integrating every element of the ABCDE model in palliative care.
Kajian Psikologis Terhadap Stimulasi Visual Alam Pembelajaran PAI untuk Anak Usia Sekolah Dasar/MI
Authors: Saidah Nur 
Published: September 2024

Menurut psikologi perkembangan anak-anak di sekolah dasar, setidaknya ada dua alasan utama pemanfaatan rangsang visual dalam proses belajar-mengajar. Pertama, stimulasi visual yang lebih menarik untuk memperkaya motitvasi anak dalam belajar, karena siswa akan menikmati proses ini, bahan-bahan yang dapat dijelaskan dengan mudah, metode akan bervariasi dan siswa selves akan melibatkan mereka dalam proses belajar-mengajar, tidak hanya mendengar pelajaran dari guru, tetapi juga mengamati, mencari atau mendemonstrasikan pesan dari ilustrasi. Kedua, stimulasi visual yang sesuai dengan perkembangan psikologis anak-anak di sekolah dasar karena media ini menjelaskan konsep abstrak menjadi konkrit dan menyederhanakan kerumitan pelajaran. Hal ini sangat pmti11g untuk proses belajar PAI yang kebanyakan terdiri dari bahan-bahan dmgan konsep abstrak. Selain itu penggunaan stimulasi visual akan memungkinkan guru membuat joyful learning sehingga belajar siswa tidak di bawah tekanan dan proses pembelajaran PAI akan produktif, penuh kreativitas, aktivitas, efektivitas dan kegembiraan.

Published: September 2024

Usia anak Sekolah Dasar/Madrasah Ibtidaiyah di Indonesia pada umumnya berkisar antara 6-12 tahun. Pada usia tersebut berdasarkan teori kognitif yang dikemukakan oleh Piaget termasuk dalam fase operasional konkrit, dimana aspek berfikir siswa cenderung pada hal-hal yang konkrit. Anak juga masih senang bermain, karena bermain adalah suatu kebutuhan bagi anak. Sesuai dengan kondisi psikologis anak dan kondisi fisik anak yang masih dalam pertumbuhan, maka rancangan pembelajaran yang disusun dengan bermain, membuat anak belajar sesuai dengan tuntutan taraf perkembanganya. Oleh karena itu pendekatan learning by playing sangat cocok diterapkan pada pelajaran sains tingkat SD / MI, karena didasari aspek psikologi siswa yang masih senang bergerak dan aspek berfikirnya yang cenderungpada hal-halyang konkrit.
Konsep Edutaiment Dalam Pembelajaran di Tingkat SD/MI (Antisipasi Keterkejutan Mental Anak Pada Masa Transisi Dari TK/RA ke SD/MI)
Authors: Suyadi Suyadi 
Published: September 2024

Anak-anak SD/MI pada masa-masa awal kebanyakan mengalami keterkejutan mental dan intelektual. Sebab, ketika mereka duduk di bangku TK, mereka belajar dengan bermain, bernyanyi, dan bercerita. Tetapi, ketika mereka masuk SD, harus meninggalkan pola pembelajaran di TK/RA dan diganti dengan pembelajaran berbasis logika. Atas dasar ini, diperlukan konsep pembelajaran yang dapat menghubungkan antara TK/RA ke SD/MI sehingga keterkejutan mental dan intelektual anak didik dapat diantisipasi. Dalam hal ini, konsep pembelajaran berbasis edutainment yakni pembelajaran yang memasukkan nuansa-nuansa entertaint, tetapi tidak mengurangi nilai-nilai edukatif yang diajarkan bisa digunakan.

The BCL11A transcription factor stimulates the enzymatic activities of the OGG1 DNA glycosylase
Authors: Petrachkova Tetiana , Soldatkina Olha , Leduy Lam , Nepveu Alain 
Published: September 2024

Abstract
The BCL11A transcription factor has previously been shown to interact with and stimulate the enzymatic activities of the NTHL1 DNA glycosylase and Pol β polymerase. Here we show that BCL11A and a smaller peptide encompassing amino acids 160 to 520 can interact with the 8-oxoguanine DNA glycosylase, OGG1, increase the binding of OGG1 to DNA that contains an 8-oxoguanine base and stimulate the glycosylase activity of OGG1. Following BCL11A knockdown, we observed an increase in oxidized purines in the genome using comet assays, while immunoassays reveal an increase in 8-oxoG bases. Structure-function analysis indicates that the stimulation of OGG1 by BCL11A requires the zinc fingers 1, 2 and 3 as well as the proline-rich region between the first and second zing finger, but a glutamate-rich region downstream of zinc finger 3 is dispensable. Ectopic expression of a small peptide that contains the three zinc fingers can rescue the increase in 8-oxoguanine caused by BCL11A knockdown. These findings, together with previous results showing that BCL11A stimulates the enzymatic activities of NTHL1 and the Pol β polymerase, suggest that high expression of BCL11A is important to protect cancer cells against oxidative DNA damage.

Breaking Down the Wall: The Effect of Immigration Enforcement and Nonprofit Services on Undocumented Student Academic Performance
Authors: Hawes Daniel P. , Chand Daniel E. , Calderon Maria Apolonia 
Published: September 2024

Abstract
Much of public administration and nonprofit research centers on issues of race and gender, but citizenship remains underdeveloped for a variety of reasons, especially due to a lack of data on the undocumented community. The first research aim of this study is to identify how immigration enforcement affects undocumented student performance. The second contribution is to understand the effect of how legal service provision by immigrant-serving nonprofits comes into play. Theoretically, these services work toward helping buffer the negative implications of community arrests and deportations on student performance. We test our theoretical arguments using a unique dataset comprised of student-level performance metrics of 2 million Latino students – including nearly 225,000 undocumented students – in Texas public schools. These data are merged with county and district-level data that reflect the level of immigrant deportations and the presence of immigrant-serving nonprofits (ISOs) in their communities. This research finds that immigration enforcement negatively impacts undocumented student performance. Furthermore, ISOs can help limit these effects and improve educational performance.
CONSENTIMENTO: CONCEITOS E PARTICULARIDADES EM TRÊS PESQUISAS SOBRE SEXUALIDADE E VIOLÊNCIA
Authors: Campos Carla Beatriz , Mota Cláudia , De Brito Thays Christina 
Published: September 2024

Neste trabalho, almeja-se discutir e problematizar o conceito de “consentimento” a partir de três pesquisas distintas que se debruçam sobre questões de sexualidade e violência. Carla Campos utiliza dados de sua pesquisa de mestrado, uma etnografia em um serviço de saúde especializado em IST-HIV/Aids, e se atém ao relato de uma interlocutora que resume sua trajetória no mercado do sexo com a frase: “eu escolhi, mas eu não aceito”. Ela argumenta que a experiência na prostituição não pode ser medida apenas pelo consentimento, ainda que este seja relevante. Cláudia Mota problematiza o conceito e a contextualização da exploração sexual de crianças e adolescentes, a partir de casos criminais julgados pelo Tribunal de Justiça do Distrito Federal e Territórios – TJDFT. Thays Brito, a partir da sua pesquisa ainda em desenvolvimento, argumenta que o consentimento está diretamente vinculado ao que se reconhece como violência sexual, contribuindo para a invisibilização do estupro marital, no contexto de uma estrutura social colonial, machista e patriarcal. As três pesquisas buscam evidenciar a complexidade e a fragilidade do conceito de consentimento, definido a partir de um ideal moderno de sujeito, diante das realidades sociais estudadas. A partir disso, visa-se problematizar “consentimento” como um conceito chave para a compreensão da violência sexual e de gênero, cuja repercussão se nota nos processos de Estado e de produção da lei, bem como na análise de desigualdades.
“PARA QUE SERVE O SANGUE, SENÃO PARA SER DERRAMADO?”: VIOLÊNCIA RACIAL ENTRE A SURREALIDADE E A MATERIALIDADE EM CANDYMAN (1992; 2021)
Authors: Ferreira da Silva Mário , Lemes do Nascimento Wagner 
Published: September 2024

A partir da etnografia fílmica de dois filmes da franquia Candyman - o primeiro, de 1992, e sua sequência mais recente, lançada em 2021 -, realizamos uma reflexão sobre as possíveis articulações entre marcadores sociais da diferença, questões de pertencimento, espaço, violências raciais e de classe. De maneira mais específica, buscamos engendrar o potencial do cinema de horror para a compreensão do fenômeno do racismo e suas consequências perversas para os corpos e subjetividades negras. Argumentamos que tanto O Mistério de Candyman (1992) quanto A Lenda de Candyman (2021) têm abordagens distintas sobre o fenômeno do racismo, mas complementares, seja na dimensão surrealista e etérea do primeiro quanto na materialidade e frontalidade do último. Em ambas as obras o racismo não aparece apenas como um arcaísmo do passado, encerrado com o fim do tráfico transatlântico, mas como um vestígio a assombrar, ainda hoje, a vida não apenas dos negros e negras norte-americanas, mas de todos aquelas e aqueles que são herdeiros da diáspora africana.
Experimental investigation on post-installed lap splices in ordinary and steel fiber-reinforced concrete

Published: September 2024

AbstractThe design of post-installed lap splices typically relies on provisions derived from cast-in-place reinforcing bars (rebars). However, some bond characteristics of post-installed rebars show significant differences compared to cast-in-place rebars, especially when using high-performance mortars. To quantify the bond strength for design purposes, a sound understanding of differences in bond stress distribution, splitting failure mode, and load transfer mechanisms is crucial. This study offers new experimental evidence on these aspects, focusing on the impact of different high-performance injection mortars, lap lengths, and the incorporation of hooked steel fibers in the concrete. Direct tension tests were conducted on spliced post-installed and cast-in-place rebars. Fiber-optic sensors were used to measure strains quasi-continuously on the rebars, minimizing interference on the bond. The findings reveal that post-installed lap splices yield slightly higher bond strength than their cast-in-place counterparts, mainly due to the higher bond stiffness of the mortars. However, this advantage is limited by the bond behavior of the cast-in-rebar within the post-installed lap splice, particularly in conditions of poor confinement. In ordinary strength concrete, cast-in-place rebars exhibit an approximately constant bond stress distribution, as typically assumed for design purposes; by contrast, post-installed rebars show a pronounced non-linear distribution. Furthermore, an addition of steel fibers alters the bond stress of the rebars, resulting in a non-linear distribution in all cases. The study reveals a 20% increase in bond strength of lap splices in concrete reinforced with 80 $$\hbox {kg}/\hbox {m}^3$$

of steel fibers. Moreover, they improve the ductility of bond failure for post-installed lap splices.

The booming Information Technology (IT) sector has led to high job stress due to intense workloads and technological changes worldwide. Examining the relationship between job stress, satisfaction, and performance is vital for employee well-being and productivity in IT industry. The primary objective of this research was to analyse how job stress and job satisfaction collectively impact job performance in IT sector employees of Delhi-NCR. IT professionals (n=255) working in service-based company from various roles and experience levels were recruited. Participants' perceived levels of job stress, job satisfaction, and job performance using validated scales. Through statistical analyses, it was observed that higher levels of job satisfaction will be associated with lower job stress and enhanced job performance. Conversely, elevated job stress is expected to correlate with decreased job satisfaction and diminished job performance. The demographic and work-related variables of the study added context to these findings by elucidating personal experiences, working conditions, communication, and contextual factors that may moderate these relationships. By exploring the multifaceted connections between job stress, job satisfaction, and job performance, this study provides a valuable insight that can inform evidence-based practices for fostering healthier and more productive work environments in the IT industry.
