Published: December 2023

Abstract
Rock discontinuity mapping techniques, such as scanlines on slopes or exposed vertical surfaces, can collect data on discontinuity characteristics required to assess the rock’s stability. When slope conditions are highly weathered, or it is challenging to identify discontinuity characteristics using a scanline mapping survey, other methods must be used to obtain this information. One of them employs borehole wall acoustic imaging. This method is sophisticated, fast, and accurate for getting discontinuity characteristic data, but it has a disadvantage in that it requires preliminary drilling work. This issue can be solved if it is done in conjunction with the work of exploration or geotechnical drilling. This study aims to compare the discontinuity characterization data recorded using borehole wall acoustic imaging and scanline methods by considering the advantages and disadvantages of both approaches. The characterization data is essential for assessing rock mass quality. When these two methods are combined in mining activities, they will provide added value by utilizing the right technology and ensuring high accuracy while following good mining practices.

Abstract
The teleseismic receiver function method was used to investigate the crustal structure in West Sumatra, Jambi, and Riau Islands regions. These regions have a high level of seismicity because it is in an active tectonic zone where the oblique subduction between the Indo-Australian and Eurasian plates occurs. This study aims to determine the depth of Moho discontinuity and the presence of subducting slab beneath 6 BMKG seismic stations that form a line perpendicular to the trench and cover 3 different geological zones. PPSI and RASM are in the forearc zone, SKSM is in the volcanic arc zone, and MBBI, JMBI, and DSRI are in the back-arc zone. This study used teleseismic earthquake record data with epicentral distance between 30°-90° from the receiver and magnitude 6 or more. The iterative time-domain deconvolution and receiver function migration techniques were applied to estimate the depth of Moho discontinuity and the presence of subducting slab. The depth of Moho discontinuity in West Sumatra, Jambi, and Riau Islands regions ranges from 21-39 km and generally deeper in the volcanic arc zone possibly due to the isostatic effect. Moho is at a depth of 21-29 km in the forearc zone, 36-39 km in the volcanic arc zone, and 30-36 km in the back-arc zone. Then the subducting slab was observed at a depth of 20 km under PPSI station to 200 km under MBBI station.

Published: December 2023

Abstract
Due to mountainous morphology, meeting the freshwater demand for daily consumption in some villages in the Citatah karst area is problematic. Some water springs exist in some parts of the valley and slopes. The water flows through pipes connecting people’s houses by pumping it using electricity. To know the potential of the groundwater in the area, we conducted geophysical surveys in a test area close to known dig wells. These are Transient Electromagnetic (TEM) and DC-resistivity methods. TEM data were collected using an in–loop transmitter-receiver configuration with Temfast 48 devices with 5 m × 5 m and 10 m × 10 m wire loops. We acquired resistivity data using a 4-point light 10w IP device, producing resistivity and chargeability data. In this preliminary result, we show only resistivity distribution. We validated the processed TEM and resistivity data with the data from seven dig wells. Our results deliver good results. The resistivity data reveals low resistivity anomalies ranging from 26.5 Ωm to 58.5 Ωm. This low resistivity zone lies at 0.6 m – 1.45 m depth associated with groundwater level.

Abstract
Co-seismic deformation is a sudden change in the earth’s surface in a fault zone. Therefore, with modern satellite imagery, it is possible to investigate. Synthetic Aperture Radar (SAR) data from Mission Sentinel-1 is one example of satellite imagery that can be used to identify deformation. We employ the interferometry method by utilizing the Interferometric synthetic aperture radar Scientific Computing Environment (ISCE) and another InSAR software to monitor the co-seismic ground deformation in the form of line-of-sight (LOS) displacement. This research focused on the Brebes Segment of the Baribis-Kendeng Fault Zone and applied the interferometry method for the March 22, 2015, Balapulang earthquake (M4.7) and December 11, 2020, Brebes earthquake (M4.2). The earthquake event choice is based on the shallow depth of the hypocenter, which represents the earthquake originating from the fault in the crustal, not the megathrust subduction. The results show that despite the earthquake occurring under the thick quaternary sediment of the north shore of Java Island, the deformation caused by the co-seismic is still emerging to the surface. The LOS displacement was detected within the range of 6 cm from the ascending and descending track of the satellite sensors. Furthermore, this result may provide new information on the Baribis-Kendeng Fault zone, specifically the Brebes Segment.
Perceived and Received Social Support and Illness Acceptance Among Breast Cancer Patients: The Serial Mediation of Meaning-Making and Fear of Recurrence
Authors: Krok Dariusz , Telka Ewa , Kocur Dagna 
Published: December 2023

Abstract

Background and Purpose
The literature indicates connections between social support and acceptance of a personal diagnosis of breast cancer, but these relationships are likely to be mediated due to numerous connections between social support and illness acceptance with meaning-making and fear of recurrence. We decided to investigate whether meaning-making and fear of recurrence serially mediated the relationship between perceived and received social support and illness acceptance.

Methods
The current research examined 246 adult women patients with a breast cancer diagnosis who were undergoing radiotherapy/chemotherapy treatment in oncological hospitals. This cross-sectional study based on a mediational model was reported according to the STROBE checklist.

Results
Our results supported the mediational model in which meaning-making and fear of recurrence serially mediated the relationship of both perceived and received social support with illness acceptance. Furthermore, the mediating power of meaning-making was more significant than the fear of recurrence.

Conclusion
Meaning structures and anxiety played an important mediating role in breast cancer patients. Finding additional meaning and goals and experiencing lower fear enables the patients to effectively make use of social support and accept their illness.

Practice implications
The current study identified factors that increase illness acceptance among breast cancer patients as it showed that patients can gain a greater understanding of the nature of their illness by becoming more aware of their own goals and values and reduce anxiety by learning about their current state of the illness.
Voices Behind Images: Exploring Left-Behind Children’s Lives with Grandparents through Photovoice

Published: December 2023

Abstract
Today, many children are living with their grandparents in rural hometowns whilst their parents migrate to work in cities. This qualitative study explores these left-behind children’s perspectives of grandparental involvement in their lives through Photovoice. Thirty left-behind children (63% female, mean age = 12 years) in a major labour-sending rural area in southwest China joined five-session Photovoice groups, during which they took photos that best represented their lives with their grandparents. Visual data of eighty-four photos were analysed with thematic analysis. The most prominent themes were living environments and daily routines with grandparents, followed by grandparents’ material support, time spent together, reciprocal support and perceived cultural traditions from the grandparents. Boys highlighted more material support from their grandparents in their shared photos, whereas girls focused more on their perceptions of cultural traditions being passed from their grandparents. This study illustrates the multifaceted nature of intergenerational solidarity and highlights the protective roles grandparents play in left-behind families in the labour migration context. The findings suggest the importance of using strength-based, culturally sensitive social work research (e.g. Photovoice techniques) and practices (e.g. community empowerment) to foster quality grandparental companionship and intergenerational bonding in left-behind families.

Published: December 2023

Abstract
Ivermectin has been widely used for antiparasitic drug, and has recently shown a broad-spectrum antiviral activity, including anti-Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). However, the pharmacokinetic property of ivermectin has not been fully investigated yet. During the plasma preparation, ~32–46% of ivermectin was found in the precipitation. An Liquid Chromatograph-Mass Spectrometer (LC–MS/MS) method for ivermectin in the whole blood samples from beagle dogs was developed and validated. The specificity, accuracy, precision (intra-day and inter-day), matrix effect, recovery and stability of analyte reported here are satisfied with the criteria of Food and Drug Administration (FDA)-Bioanalysis guideline. The oral administrations pharmacokinetics of ivermectin in beagle dogs under fasting and after high-fat meal were studied, and the following parameters were obtained: fasting Cmax, 104 ± 35 μg·L−1; area under the concentration–time curve (AUC0–∞), 2,555 ± 941 h·μg·L−1; and high-fat meal Cmax, 147 ± 35 μg·L−1; AUC0–∞, 4,198 ± 1,279 h·μg·L−1. When the P-gp inhibitor curcumin was also coadministrated orally, Cmax and AUC0–∞ were found to be 177 ± 57 and 4,213 ± 948 h·μg·L−1, respectively. With the comparison to fasting treatment, coadministration of P-gp inhibitor curcumin resulted in increase of the exposure of ivermectin by 1.6-fold, while the exposure after the high-fat diet versus fasting was increased approximately in 1.4-fold, indicating that alternative absorption might play an important role for increasing the exposure of ivermectin for future clinic applications.

ABSTRACT

Background
Intradialytic hypotension (IDH) is a common hemodialysis complication causing adverse outcomes. Despite the well-documented associations of ambient temperatures with fluid removal and pre-dialysis blood pressure (BP), the relationship between ambient temperature and IDH has not been adequately studied.

Methods
We conducted a cohort study at a tertiary hospital in southern Taiwan between 1 January 2016 and 31 October 2021. The 24-h pre-hemodialysis mean ambient temperature was determined using hourly readings from the weather station closest to each patient's residence. IDH was defined using Fall40 [systolic BP (SBP) drop of ≥40 mmHg] or Nadir90/100 (SBP &lt;100 if pre-dialysis SBP was ≥160, or SBP &lt;90 mmHg). Multivariate logistic regression with generalizing estimating equations and mediation analysis were utilized.

Results
The study examined 110 400 hemodialysis sessions from 182 patients, finding an IDH prevalence of 11.8% and 10.4% as per the Fall40 and Nadir90/100 criteria, respectively. It revealed a reverse J-shaped relationship between ambient temperature and IDH, with a turning point around 27°C. For temperatures under 27°C, a 4°C drop significantly increased the odds ratio of IDH to 1.292 [95% confidence interval (CI) 1.228 to 1.358] and 1.207 (95% CI 1.149 to 1.268) under the Fall40 and Nadir90/100 definitions, respectively. Lower ambient temperatures correlated with higher ultrafiltration, accounting for about 23% of the increased IDH risk. Stratified seasonal analysis indicated that this relationship was consistent in spring, autumn and winter.

Conclusion
Lower ambient temperature is significantly associated with an increased risk of IDH below the threshold of 27°C, irrespective of the IDH definition. This study provides further insight into environmental risk factors for IDH in patients undergoing hemodialysis.
A new method for generating random correlation matrices
Authors: Archakov Ilya , Hansen Peter Reinhard , Luo Yiyao 
Published: December 2023

SummaryWe propose a new method for generating random correlation matrices that makes it simple to control both location and dispersion. The method is based on a vector parameterization, $\gamma =g(C)$, which maps any distribution on $\mathbb {R}^{n(n-1)/2}$ to a distribution on the space of nonsingular $n\times n$ correlation matrices. Correlation matrices with certain properties, such as being well-conditioned, having block structures, and having strictly positive elements, are simple to generate. We compare the new method with existing methods.
Exploring teacher classroom behavior and wellbeing from the student perspective
Authors: Moskowitz Sharona 
Published: December 2023

Abstract
In recent years, an increasing drumbeat around emotion research in ELT has brought to the fore an appreciation of teacher psychology and the emotional underpinnings of the teacher–student relationship. This study explores how students report their teacher’s classroom behavior and how those observations lead learners to make broader impressions about the teacher’s mental state. As part of a larger study, 129 adult EFL students took a web survey about their teacher’s classroom behavior, perceived overall happiness, and their perceived wellbeing. Results revealed that teacher behavior was strongly correlated with perceived teacher wellbeing and happiness, meaning that based on how teachers behave in the classroom, students make far-reaching assumptions about their wellbeing beyond the classroom. Due to the phenomenon of emotional contagion, when students think their teachers are happy, they may also feel more positive emotions in the classroom. Suggestions for teachers are discussed, such as strategies for making the best of challenging situations and promoting healthy student relationships as a means to promote teacher and learner wellbeing. Suggestions for potential institutional changes are also made.
Degradation of citrate synthase lacking the mitochondrial targeting sequence is inhibited in cells defective in Hsp70/Hsp40 chaperones under heat stress conditions
Authors: Hayashi Mayuko , Kawarasaki Tomoyuki , Nakatsukasa Kunio 
Published: December 2023

Abstract
Most nucleus-encoded mitochondrial precursor proteins are synthesized in the cytosol and imported into mitochondria in a post-translational manner. In recent years, the quality control mechanisms of nonimported mitochondrial proteins have been intensively studied. In a previous study, we established that in budding yeast a mutant form of citrate synthase 1 (N∆Cit1) that lacks the N-terminal mitochondrial targeting sequence, and therefore mislocalizes to the cytosol is targeted for proteasomal degradation by the SCFUcc1 ubiquitin ligase complex. Here, we show that Hsp70 and Hsp40 chaperones (Ssa1 and Ydj1 in yeast, respectively) are required for N∆Cit1 degradation under heat stress conditions. In the absence of Hsp70 function, a portion of N∆Cit1-GFP formed insoluble aggregates and cytosolic foci. However, the extent of ubiquitination of N∆Cit1 was unaffected, implying that Hsp70/Hsp40 chaperones are involved in the postubiquitination step of N∆Cit1 degradation. Intriguingly, degradation of cytosolic/peroxisomal gluconeogenic citrate synthase (Cit2), an endogenous substrate for SCFUcc1-mediated proteasomal degradation, was not highly dependent on Hsp70 even under heat stress conditions. These results suggest that mitochondrial citrate synthase is thermally vulnerable in the cytosol, where Hsp70/Hsp40 chaperones are required to facilitate its degradation.
DISCRIMINATION IS ASSOCIATED WITH HIGHER ODDS OF HOSPITALIZATIONS AMONG OLDER AFRICAN AMERICANS

Published: December 2023

Abstract
Everyday discrimination—experiences of being treated unfairly based on background characteristics like race—is linked to poor physical and mental health throughout the lifespan. Whether more experiences of discrimination are associated with higher likelihood of being hospitalized in older African Americans has not been explored. Hospitalization can represent both poor health and healthcare access. Participants were community-dwelling African Americans from the Rush Memory and Aging Project or Minority Aging Research Study, longitudinal studies of aging (N=301 with at least 12 months linked Medicare fee-for-service claims; mean age 72.5 years (standard deviation [SD]: 5.7), 79% female). Discrimination was assessed using the Detroit Area Study Everyday Discrimination Scale. Hospitalizations (sub-categorized as elective/non-elective, surgical) were quantified using Medicare claims. Mixed-effects ordinal logistic regression models tested associations between baseline discrimination and subsequent odds of hospitalizations per year (0, 1, 2+). The mean baseline discrimination score was 1.7 (SD: 2.2). Over an average 6.5 years (SD: 4.1), 160 participants had at least 1 hospitalization (respectively, 118, 87, and 127 participants had at least 1 nonelective, elective, or surgical hospitalization). Adjusting for age, sex, education, income, depressive symptoms, and medical comorbidity, more experiences of discrimination were associated with higher odds of hospitalization (odds ratio [OR] per point higher on discrimination score=1.12, 95% CI: 1.03-1.22), and higher odds of nonelective (OR=1.12, 95% CI: 1.01-1.24), but not surgical or elective hospitalizations. Drivers of these associations, which may include preventive healthcare avoidance due to discrimination or poor health due to the chronic stress response to discrimination, should be explored.

Authors: Rodriguez Miriam , Mendoza Lisandra , Garcia Patricia , Duarte Andres , Padron Dilianna , Marsiske Michael , Fiala Jacob , Duara Ranjan 
Published: December 2023

Abstract

Objectives
Hispanics are 1.5x more likely to develop Alzheimer’s disease (AD) when compared to White non-Hispanics (WNHs). There is also evidence to support that cognitive performance disproportionately reflects neuropathology among Hispanics and that functional decline is concurrent with the accumulation of AD biomarkers. The current study aimed to examine relationships between AD biomarkers and a functional measure among Hispanic and WNH older adults. It was hypothesized that the functional measure would be strongly related to AD biomarkers among Hispanics.

Methods
The modified clinical dementia rating scale (mCDR) was administered in the participants primary language (English or Spanish) to WNH (n=203) and Hispanic (n=258) older adults who were cognitive normal or diagnosed with Mild Cognitive Impairment (MCI) or dementia. Invariance SEM models were used to compare the pattern of relationships between the mCDR and neurocognitive test performance, MRI volumes, and amyloid load adjusting for age, education, ApoE4 status, and intracranial volume.

Results
Model fit was good and not significantly worsened by imposing strict structural invariance. Nested model comparisons indicated that regression weights and correlations among measures differed by group, suggestive of moderation by Hispanic status. Among Hispanic participants, sex (♌=-0.17, p&lt;.05) and Amyloid load (♌=0.25, p&lt;.001) significantly predicted mCDR scores. MRI volumes significantly predicted MCDR scores among both Hispanic (♌=-0.51, p&lt;.001) and WNH participants (♌= -0.42, p&lt;.001).

Conclusions
Functional measures like the mCDR may better correlate with Amyloid load among Hispanic older adults than among WNHs, while the correlation with MRI volumes may be comparable in both groups.

Published: December 2023

Abstract
Delayed dementia diagnosis may exacerbate dementia symptoms and reduce opportunities for care arrangements, further harming older adults’ health and well-being. Social isolation may increase the risk of delayed dementia diagnosis via a lack of support that prevents seeking help and accessing primary and specialty care for diagnosis. We investigated the association between social isolation and missed/delayed dementia diagnosis using the Health and Retirement Study (2004-2018) linked with the Medicare Claims record. We defined social isolation as having 3 or more affirmative responses to 6 questions about living arrangements, family/friend contact, and social participation. We defined missed/delayed diagnosis as having no clinical diagnosis documented in Medicare in the presence of an algorithm-defined dementia diagnosis in the survey; or having dementia diagnosed more than 3 years after meeting the survey-based algorithmic criterion for dementia. We fitted logistic regression models, adjusting for sociodemographic and health characteristics. Among 2,417 people in our sample (mean age 82.4(SD 5.85); 60% women), 54.7% of older adults experienced social isolation at the time of survey-based dementia onset, 41.5% had missed/delayed diagnosis, and 22.1% died with no dementia diagnosis in their Medicare record. Preliminary results indicate that social isolation was not associated with increased odds of missed/delayed diagnosis (OR 1.09 95% CI 0.90, 1.32). Our findings suggest that social isolation may not be a major driver of healthcare access and system factors pertinent to clinical documentation of dementia. To corroborate findings, we plan to refine our models (e.g., accounting for attrition and selection).
