This study focuses on the governance of Kelompok Perempuan Kreatif Mandiri/Independent Creative Women Group (KPKM) which is the beneficiary of women's empowerment program from Corporate Social Responsibility (CSR) PT Perusahaan Gas Negara Tbk. The paper aims to identify and describe, how organizational structure impacts governance patterns and the outcomes. It used a persuasive case study approach, where the data collection process is carried out through in-depth interviews with relevant stakeholders. Likewise, researchers conducted close observation, supported with literature review from journals, digital media and books, to enrich the study. The research findings reveal that the absence of regeneration in the organizational structure causes repetitive governance pattern since its establishment, same persons are appointed as caretakers in several bodies, depending on a central figure, and only able to innovate through the intervention of outsiders (other parties). Furthermore, there is a concern regarding potential digression, as quoted from Lord Acton's letter to the Bishop of Creighton in 1887; "Power tends to corrupt and absolute power corrupts absolutely”.
Penelitian ini berfokus pada tata kelola Kelompok Perempuan Kreatif Mandiri yang merupakan penerima manfaat program pemberdayaan perempuan dari PT Perusahaan Gas Negara Tbk. Studi bertujuan untuk mengidentifikasi, dan menguraikan bagaimana struktur organisasi berdampak pada pola tata kelola, dan hasil. Penelitian menggunakan pendekatan studi kasus persuasif, dimana proses pengumpulan data dilakukan melalui wawancara mendalam (in-depth interview) terhadap para pemangku kepentingan yang relevan, didukung dengan observasi dan telaah literatur. Temuan penelitian menyatakan bahwa tidak adanya regenerasi dalam struktur organisasi menyebabkan organisasi bergerak dengan pola tata kelola serupa sejak berdiri, bergantung pada figur sentral, dan hanya mampu berinovasi melalui intervensi pihak lain. Lebih lanjut perlu diwaspadai potensi timbulnya penyimpangan, sebagaimana kutipan surat Lord Acton kepada Uskup Creighton pada 1887; “Power tends to corrupt and absolute power corrupts absolutely” (kekuasaan cenderung korup, dan kekuasaan mutlak pasti korup).

Published: March 2024

BackgroundHome-based remote audiometry has been emerging due to the increasing accessibility of mobile technology and the need for healthcare solutions that are available worldwide. However, the challenges presented by uncontrolled conditions, such as noisy environments, could compromise the reliability of the hearing assessment.MethodIn this study, we evaluate the reliability of the Jacoti Hearing Center (JHC) smartphone application in differing ambient noise environments. Hearing test data were synchronized from the JHC application to the Jacoti earCloud database (JEC). We collected, de-identified, and analyzed real-world, home-based audiometric test data spanning from 2015 to 2023, extracted from the JEC database. A set of exclusion criteria was defined to perform data cleaning, ensuring the removal of incomplete and unreliable data, as well as, data from users who had completed a large number of tests. The final dataset comprised 9,421 test and retest threshold pairs from 1,115 users. Hearing tests conducted under relatively quiet and noisy conditions were categorized based on threshold-to-noise ratio.ResultsThe test-retest reliability of the JHC application demonstrated an average absolute difference of 4.7 dB within the range from 20 to 75 dB, ranging from 3.7 dB to 6.2 dB across frequencies. A strong positive correlation of 0.85 was found between test and retest thresholds. Moreover, the pure tone average differences were within 5 dB for 84.6% of the audiograms. No clinically significant effects of ambient noise were observed on thresholds determined between 20 and 75 dB HL.ConclusionsOur results demonstrate that the JHC application can provide reliable audiometric data for hearing loss, even in non-ideal acoustic conditions. This highlights the potential of home-based audiometric assessment, reinforcing the idea that, with continuous noise monitoring and noise-aware control of the testing procedure, remote audiometry can be reliable.
Content teachers’ beliefs and attitudes toward working with multilingual learners through integrative approaches

Published: March 2024

IntroductionThe fast-growing population of multilingual learners (MLs) in U.S. schools calls for ML-focused instructional support from content classroom teachers to acquire content knowledge and language proficiency simultaneously. However, teachers in general lack competency in content-language integrative pedagogy that builds on MLs’ transliterate capabilities, placing MLs at a greater disadvantage in the content classroom. Given that teachers’ classroom practices are shaped by their underlying language ideologies, it is important to examine what ideological beliefs and attitudes teachers are operating with for their day-to-day work with MLs. Framed by scholarship on content-language integrated instruction, language ideologies, and transliteracies approaches, this study examined the relations between content teachers’ ideological beliefs and attitudes toward teaching MLs in the content classroom and several teacher-related variables.MethodsThis study employed a sequential mixed-methods design for a more comprehensive understanding of teachers’ ideologies about working with MLs. Quantitative data analysis was conducted by confirmatory factor analysis and multiple regressions using survey responses of in-service content teachers (N=100) followed by focus group interviews (N=24).ResultsResults of a confirmatory factor analysis using a survey suggested that teachers who were more likely to endorse English-only monolingual pedagogy did not necessarily view themselves as having lesser sensitivity to MLs’ backgrounds in their classroom. Results of regression analyses showed that teachers using pull-out or push-in instruction were more inclined to support language-integrated content teaching and considered themselves more sensitive to MLs’ backgrounds than teachers who instruct specialized content. Interestingly, the specialized content teachers having a greater percentage of MLs in their classroom were more supportive of the language-integrated content teaching pedagogy than other teachers using the teaching role. Analysis of focus groups provided contextualized rationales for teachers’ chosen stances toward the English-only monolingual, separatist pedagogy or the transliterate, integrative pedagogy for MLs.DiscussionThe findings demonstrated that teachers’ ideologies were not merely individual beliefs but also intertwined with the hegemonic language ideologies of the larger education system. The complexity of the shifting ideologies points to the pressing need for integrating ML-specific attention into teacher education and ongoing professional development programs.

ObjectiveThis study aimed to identify the amount of weight loss needed in patients with obesity to improve metabolic syndrome (MetS), a risk factor for cardiovascular disease (CVD), over a long period of time.MethodsA total of 576 patients with obesity were enrolled in this study. Effects of continuous physician-supervised weight loss on the cumulative MetS components excluding abdominal circumference (defined as obesity-related CVD risk score) were investigated during a 5-year follow-up period. The extent of weight loss required to reduce the obesity-related CVD risk components was assessed using receiver operating characteristic (ROC) curve analyses.ResultsOf the 576 participants, 266 completed 5-year follow-up, with 39.1% and 24.1% of them achieving ≥5.0% and ≥7.5% weight loss at the 5-year follow-up, respectively. The area under the ROC curve for reducing the obesity-related CVD risk components was 0.719 [0.662–0.777] at 1 year and 0.694 [0.613–0.775] at 5 years. The optimal cut-off value for weight loss was 5.0% (0.66 sensitivity and 0.69 specificity) and the value with 0.80 specificity was 7.5% (0.45 sensitivity) at 5 years. Greater reductions in weight were associated with greater improvements in the obesity-related CVD risk score at all follow-up periods (P-trend &lt;0.001). Obesity-related CVD risk score was significantly improved by 5.0–7.5% and ≥7.5% weight loss at 1 year (P = 0.029 and P &lt; 0.001, respectively) and ≥7.5% weight loss at 5 years (P = 0.034).ConclusionsA weight loss of ≥5.0% at 1 year and ≥7.5% at 5 years could reduce the number of obesity-related CVD risk components in patients with obesity.

Published: March 2024

BackgroundAmyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disease, which leads to muscle weakness and eventual paralysis. Numerous studies have indicated that mitophagy and immune inflammation have a significant impact on the onset and advancement of ALS. Nevertheless, the possible diagnostic and prognostic significance of mitophagy-related genes associated with immune infiltration in ALS is uncertain. The purpose of this study is to create a predictive model for ALS using genes linked with mitophagy-associated immune infiltration.MethodsALS gene expression profiles were downloaded from the Gene Expression Omnibus (GEO) database. Univariate Cox analysis and machine learning methods were applied to analyze mitophagy-associated genes and develop a prognostic risk score model. Subsequently, functional and immune infiltration analyses were conducted to study the biological attributes and immune cell enrichment in individuals with ALS. Additionally, validation of identified feature genes in the prediction model was performed using ALS mouse models and ALS patients.ResultsIn this study, a comprehensive analysis revealed the identification of 22 mitophagy-related differential expression genes and 40 prognostic genes. Additionally, an 18-gene prognostic signature was identified with machine learning, which was utilized to construct a prognostic risk score model. Functional enrichment analysis demonstrated the enrichment of various pathways, including oxidative phosphorylation, unfolded proteins, KRAS, and mTOR signaling pathways, as well as other immune-related pathways. The analysis of immune infiltration revealed notable distinctions in certain congenital immune cells and adaptive immune cells between the low-risk and high-risk groups, particularly concerning the T lymphocyte subgroup. ALS mouse models and ALS clinical samples demonstrated consistent expression levels of four mitophagy-related immune infiltration genes (BCKDHA, JTB, KYNU, and GTF2H5) with the results of bioinformatics analysis.ConclusionThis study has successfully devised and verified a pioneering prognostic predictive risk score for ALS, utilizing eighteen mitophagy-related genes. Furthermore, the findings indicate that four of these genes exhibit promising roles in the context of ALS prognostic.

Published: March 2024

We carried out measurements of the CO2 system parameters to evaluate the impact of carbonate and nutrients’ chemistry on phytoplankton populations in the Gulf of Guinea (GoG). The seasonal variations of the CO2 system parameters (fCO2, DIC, pH and TA) along with nitrates and phosphates were quantified weekly at surface (between 0 and 5 m depth) (5.57°N - 4.57°W) in the GoG from May to December 2020. Seawater pH varied widely during the study period, ranging between 8.10-8.35 pH units; DIC and TA varied between 1810 and 2094 μmol kg-1, and between 2051 and 2216 μmol-1 respectively. DIC peaks coincided with the high upwelling period (August and September). For phytoplankton, a total of 60 species were found belonging to four taxonomic phyla: Bacillariophyta, Dinophyta, Chlorophyta and Dictyochophyta. The highest number of phytoplanktonic species were recorded for Bacillariophyta phylum with 36 species (60%). The phylum Dinophyta comprised 22 taxa (36%) and Chlorophyta and Dictyochophyta recorded only one species (2%). The highest specific diversities were observed in August and September with 29 and 26 taxa respectively and the lowest was found in October-November (5 taxa) and December (one taxa). Bacillariophyta and Dinophyta appeared throughout the entire study period. The only species for Chlorophyta phylum appeared in June and July and the Dictyochophyta’s one in May, July and August. In general, the physical (SST, SSS) and chemical (TA, DIC, pH) parameters influenced less than 50% of the phytoplankton population in the coastal area of the GoG. Our study shows that Bacillariophyta population grows up when the physicochemical parameters’ variability increase.

Published: March 2024

BackgroundThe correlation between diabetic nephropathy (DN) and gut microbiota (GM) has been suggested in numerous animal experiments and cross-sectional studies. However, a causal association between GM and DN has not been ascertained.MethodsThis research adopted MR analysis to evaluate the causal link between GM and DN derived from data acquired through publicly available genome-wide association studies (GWAS). The study utilized the inverse variance weighted (IVW) approach to assess causal association between GM and DN. Four additional methods including MR-Egger, weighted median, weighted mode, and simple mode were employed to ensure comprehensive analysis and robust results. The Cochran’s Q test and the MR-Egger method were conducted to identify heterogeneity and horizontal pleiotropy, respectively. The leave-one-out approach was utilized to evaluate the stability of MR results. Finally, a reverse MR was performed to identify the reverse causal association between GM and DN.ResultsAccording to IVW analysis, Class Verrucomicrobiae (p = 0.003), Order Verrucomicrobiales (p = 0.003), Family Verrucomicrobiaceae (p = 0.003), Genus Akkermansia (p = 0.003), Genus Catenibacterium (p = 0.031), Genus Coprococcus 1 (p = 0.022), Genus Eubacterium hallii group (p = 0.018), and Genus Marvinbryantia (p = 0.023) were associated with a higher risk of DN. On the contrary, Class Actinobacteria (p = 0.037), Group Eubacterium ventriosum group (p = 0.030), Group Ruminococcus gauvreauii group (p = 0.048), Order Lactobacillales (p = 0.045), Phylum Proteobacteria (p = 0.017) were associated with a lower risk of DN. The sensitivity analysis did not identify any substantial pleiotropy or heterogeneity in the outcomes. We found causal effects of DN on 11 GM species in the reverse MR analysis. Notably, Phylum Proteobacteria and DN are mutually causalities.ConclusionThis study identified the causal association between GM and DN with MR analysis, which may enhance the understanding of the intestinal-renal axis and provide novel potential targets for early non-invasive diagnosis and treatment of DN.
