Authors: Permana H , Awdia S A , Patonah A , Solihin S
Published: December 2023

The ultramafic rock of the Wasuponda mélange complex and the Wolo cape areas, Sulawesi classified as lhezolite, harzburgite, dunite, olivine websterite, wherlite and serpentinite. The rocks have undergone dynamic recrystallization through bulging, subgrain rotation and grain boundary migration. The olivine neoblast grain size varies from a very fine size to a mean size of around 75 μm and a mean size range of 150, 225, 300 and 425 μm. The neoblast grain size indicates that dynamic recrystallization took place with various stress at about 13 MPa to 52 MPa. The optimum recrystallization of the Malili-Wasuponda peridotite occurs at 52 MPa, while rock peridotite of the Wolo cape formed at optimum stress reached 30-32 MPa.

Published: December 2023

Underground coal gasification technology is a technology that converts coal into gaseous products through the gasification process. UCG technology is known as clean energy technology. The potential risk of UCG that can occur is groundwater contamination, this is due to gas leaking into the rock layers and the aquifer above it. An important parameter of groundwater contamination is hydraulic conductivity, obtained by the double inflatable packer method. The test results of aquifer-03 (142-151 m), the hydraulic conductivity value is 1.82 e-6 m/s - 2.16 e-6 m/s, the aquifer zone order range from the upper limit to the lower limit tends to be homogeneous in sand lithology. fine. The top layer of aquifer-04 (213-230 m), is silt lithology, the middle is silty sand lithology and the bottom is silty sand lithology. The hydraulic conductivity value is 1.22 e-6 m/s - 3.88 e-8 m/s, the range is quite wide with a difference of 2 orders, this is due to differences in grain lithological composition with finger type aquifer layers and are not interconnected. If there is a gas leak, then aquifer-03 lithology is more affected as a medium for spreading groundwater pollution than aquifer-04 lithology.

Authors: Nainggolan T B , Halawa N I T P S
Published: December 2023

Banggai Basin is controlled by the collision between Banggai-Sula micro-continent and East Sulawesi ophiolite belt, forming a thrust-sheet anticline structure that has potential to trap hydrocarbon. The Siotu-1 well was drilled right into the thrust-sheet anticline structure targeting Miocene carbonate platform layer. The same structure has proven to be an oil trap at the Tiaka oilfield which is located adjacent to the Siotu-1 well. This study aims to evaluate the presence of hydrocarbon in the Siotu-1 well with characterization of the Miocene carbonate reservoir. It is carried out by integrating petrophysical analysis from the Siotu-1 well log data and 2D seismic impedance inversion of the Tarib-1 line. Five reservoir zones have shale content values range of 21.91-37.53%, effective porosity values range of 9.7-14.62%, water saturation values range of 88.5-98.27%, and permeability values range of 2.53-8.16 mD. The results of the porosity calculation are validated by the model of seismic inversion where the reservoir zone with an acoustic impedance in the range of 7600-13450 ((m/s)/(g/cc)) is a carbonate layer with fair to excellent porosity (10 to> 25%) and reservoir zone with acoustic impedance values range of 13450-16200 ((m/s)/(g/cc)) as carbonate layer with poor porosity (< 10%). The net pay zone in reservoir zone 4 with a thickness of 4.5 feet and a net-to-gross of 0.006 are shown as the lumping result. It is concluded that Miocene carbonate reservoir in the Siotu-1 well met the criteria as a good reservoir rock but insignificant of hydrocarbon potential for further development.
Dynamic factor of safety of rock slopes due to blasting based on critical displacement and critical acceleration
Authors: Kiramang N , Prassetyo S H , Karian T , Simangunsong G M
Published: December 2023

Analysis of slope stability due to blasting based on the pseudostatic principle is considered too conservative because the slope receives a constant maximum seismic load (and hence constant acceleration) without considering the duration of the blast. In reality, the acceleration fluctuates with time and eventually diminishes. One method to analyze the stability of rock slopes due to blasting is to conduct dynamic simulations using Newmark displacement analysis to obtain the dynamic Factor of Safety (FoS) based on the magnitude of critical displacement (ucrit
) and critical acceleration (acrit
). This study was carried out using hypothetical slopes of various rock mass strengths determined from the Rock Mass Rating (RMR). A case study of a highway rock slope excavated using the drill-and-blast method was also carried out to validate the research results. The findings reveal that very good rock (RMR Class I) has FoSdynamic = 11.7, ucrit
= 6 mm, and acrit
= 0.061g, while very poor rock (RMR V) has FoSdynamic = 1.7, ucrit
= 16 mm, and acrit
= 0.035g. This result indicates that the smaller the strength of the rock mass, the smaller the critical acceleration and the greater the value of the critical displacement will be. This study reinforces the significance of critical displacement and critical acceleration in assessing the dynamic stability of rock slopes due to blasting.

Authors: Rizka  , Santoso D. , Warsa  , Mustofa M.B.
Published: December 2023

The factors of porosity and formation resistivity have a strong influence on the process of electric current conduction through saturated porous media. In this study, laboratory experiments were carried out to calculate the resistivity formation factor from electrical resistivity measurements for leachate-saturated waste in samples collected from the Bakung landfill in Bandar Lampung. The formation resistivity factor is calculated using the Archie equation by calculating the representative value of the intercept (a) and the cementation factor (m) as used by Archie in the derivative relationship between the formation resistivity factor (F) and porosity (ϕ). This study investigates the impact of leachate spatial distribution on electrical resistivity. Electrical resistivity and porosity were measured in 27 soil samples. Each soil sample was subjected to three treatments: without leachate injection, unsaturated leachate injection (physical modelling), and fully saturated leachate injection (physical modelling). The results show that resistivity formation factors and porosity have a relationship. The values of ‘a’ and ‘m’ were determined at the study site based on the relationship between formation factors and porosity. The findings should create new insights into applied geophysics.

Published: December 2023

West Java is one of the regions in Indonesia that has a complex geological structure caused by plate subduction in the south of Java Island. This resulted the formation structure of the main faults in West Java, including the Cimandiri Fault. The high level of seismicity on the Cimandiri Fault is interesting to be further researched to understand the structure of the Earth crustal, such as variations depth of the Moho layer and the determination of local velocity models of P and S waves. This study used receiver function analysis from teleseismic earthquake data with an epicentral distance of 30°-90° from the station location and magnitude ≥ 6. This study used 3 seismic stations belonging to the Meteorological, Climatological, and Geophysical Agency (BMKG) close to the Cimandiri Fault which are Sukabumi station (SKJI), Warung Kiara (WSJM), and Sukaraja (SSJM). The depth of the Moho layer at SKJI station is 34-36 km, WSJM station is 28-30 km, and SSJM station is 29-31 km which is located close to the segment from the Cimandiri Fault. A negative phase or decrease in speed was observed at the SKJI and WSJM stations which is estimated to come from the Cimandiri Fault structure which is at a depth of 17-19 km. Furthermore, the P wave velocity model at the three stations is at an interval of 7.6-8.6 km/s and the S wave velocity model is at an interval of 4.2-4.8 km/s.

Authors: Arrahman M Arif , Tohari Adrin , Perwita Cholisina Anik
Published: December 2023

Lembang district in Bandung Regency is prone to seismic risk because it is in the vicinity of a very well-known active fault called the Lembang Fault. The effort to reduce the seismic risk requires knowledge of the dynamic properties of the soils, mainly derived from young volcanic rocks. This paper presents the results of a seismic microzonation study based on microtremor measurements. In total 195 microtremor data from single-station measurements were processed using the HVSR method to estimate the dominant frequency and amplification factors. Furthermore, the Rayleigh wave ellipticity inversion has also been used to estimate the corresponding Vs profiles. The HVSR results show that the dominant frequency for the Lembang District is 0.2 Hz or higher, and the amplification factors are dominantly higher than 3. Some areas also have a lower dominant frequency than 2 Hz, especially the area with thick soft sediments. Results of the inversion show that the shear wave velocities of subsoil layers for the upper 30 m vary from 250 m/s to 300 m/s, indicating site class D. Meanwhile, the areas with Vs30 less than 250 m/s are especially located north of the Lembang Fault. Thus, the area is likely to have a stronger ground response to earthquake shaking than the other areas in Lembang District.

Authors: Salsabila R.S. , Yudistira T. , Tohari A
Published: December 2023

Palu is one of the earthquake prone coastal cities in Indonesia. The 28 September 2018 earthquake (Mw 7.5) destroyed buildings in Palu due to ground shaking amplification, liquefaction, and tsunami. This phenomenon implies the importance of soil dynamic properties knowledge as a basis for proper building design to reduce such an earthquake. This paper presents the results of microtremor measurements conducted at 110 locations in Palu to estimate the dynamic properties of alluvial and marine deposits for earthquake mitigation. The microtremor data were processed using the HVSR method to estimate dominant frequency and amplification factors. Based on these two parameters, the seismic vulnerability index value can be used to estimate the dynamic characteristic variations of the area. The results show that alluvial and marine sediments in Palu have dominant frequency values from 0.54 to 11.72 Hz, amplification from 1.64 to 6.15, and seismic vulnerability index of 1.49 to 56. Sediments with low dominant frequency and high amplification factors are mostly found in the western and eastern Palu and Mantikulore districts, which are associated with thick sediment layers. The areas with the highest amplification factor and seismic vulnerability index are Petobo and Balaroa, which experienced severe damage during the 2018 earthquake.
Estimate and Analyze The Impact to the Brittleness Index of Digital Rock Image of Carbonate
Authors: Josephus D C , Rahmareza M K , Fatkhan  , Fauzi U
Published: December 2023

Digital rock physics is a modern method of determining the elastic properties, an important parameter to analyze the brittleness index, combining the digital technique with the numerical method. This paper analyses the effect of mineral content, water saturation, fluid type, and porosity. Carbonate digital images with 501 × 450 × 482 pixels which are divided into sub-cubes of 50 pixels3 are used. Calculating stress and strain with a numerical approach to producing the modulus elastic, and then the brittleness index can be approximated. The result shows calcite and ankerite are stiffer than quartz but not resistant to shear stress. An increase in the fluid saturation decreases the modulus value linearly in the oil case but suddenly in the gas case. For porosity variation, the greater the porosity in a material or rock will make it less rigid and not easily deformed. The effect on brittleness increases when water is replaced by fluids (either oil or gas) but decreases when there is more calcite, and ankerite and also goes down if the porosity gets bigger. So this study concludes, calcite, ankerite, and increasing porosity make the material more ductile but fulfilling with fluid will make it a little more brittle.

Published: December 2023

Seismic based reservoir characterization commonly attempts to estimate petrophysical properties of a reservoir from a combination of elastic attributes resulted from seismic inversion. Two most wanted main reservoir properties to be estimated are porosity variation and hydrocarbon saturation across the reservoir. A combination of acoustic impedance (AI) and the ratio between P- and S-wave velocities (Vp/Vs ratio) based on rock physics models had been used in the earlier study to form Curved Pseudo Elastic Impedance (CPEI) attribute. However, the approach involved a fourth order polynomial in the logarithmic domain of AI and Vp/Vs ratio. A much simpler approach of combining these elastic properties to form CPEI attributes which is based on attribute rotation scheme is proposed in this study. To illustrate the methodology, we applied to well and seismic data located in the Natuna Basin, Indonesia. Results show that better attributes correlation to porosity and hydrocarbon saturation variation is achieved.

Published: December 2023

To overcome the limited information in the northern waters of Sulawesi Island, ocean bottom seismometers (OBS) were installed in the northern part of the Makassar Strait and the Sulawesi Sea. OBS data were analysed using passive seismic methods to determine the characteristics of noise and site response in the Makassar Strait and the Celebes Sea. Probabilistic Power Spectral Density (PPSD) from OBS station showed microtremor in the period 0.06 – 0.7 s, secondary microseismic peak in the period 0.9 – 2 s, secondary microseismic peak in the period 4 – 8 s, and hum in the period more than 10 s. The amplitude of the noise power is in the range of New Low Noise Model (NLNM) and New High Noise Model (NHNM) for a period <10 s and slightly above NHNM for a period >10 s for OBS IGGCAS F-type. For OBS IGGCAS G-type, the noise power amplitude is in the period < 0.7 s in the NLNM and NHNM ranges. However, there is a tendency for the noise power amplitude to be flat with an amplitude above NHNM for a period > 0.7 s. The noise power’s amplitude depends on the station’s location, climate, instruments, daily variations, and seasonal variations. Horizontal-to-Vertical Spectral Ratio (HVSR) in the North Makassar Strait shows an H/V curve with an unclear peak in the middle of the strait and multiple peaks in the eastern part of the strait with a frequency range of 1.35 – 4.7 Hz. Between the Makassar Strait and the Celebes Sea, the H/V curve shows a flat peak and multiple peaks with a frequency range of 1.10 – 4.03 Hz. Meanwhile, in the Celebes Sea, the H/V curve shows an unclear peak (unclear peak) and several peaks (multiple peaks) with a frequency range of 0.65 – 6.25 Hz.

Published: December 2023

This study aimed to determine the Moho depth using data from a single seismograph station known as JN01, located on the ITB campus in Jatinangor. The investigation focused on seismic events that occurred within a specific range of distances between 30° and 90° included a total of 34 events. The signals received were analyzed by the seismograph for each of these events. This analysis involved applying a bandpass filter ranging from 0.05 to 1 Hz. Subsequently, the receiver function method was used through a water-level deconvolution process (water-level set to 0.005, Gaussian factor 2.5). The receiver function signals from all 34 seismic events then stacked and determined the arrival time of the P-wave phases for the Ps phase at 3.063 seconds, the PpPs phase (TPpPs) at 11.408 seconds, and the PpSs + PsPs phase (TPsPs + PpSs) at 14.472 seconds. These arrival times were used in H-κ stacking to estimate the Moho depth with additional weight factors of 0.7, 0.2, and 0.1. Preliminary findings indicate that the Moho depth estimation in this area is approximately 28.4 km, and also determined a Vp/Vs ratio of about 1.733.
Behavioral estimates of mating success corroborate genetic evidence for pre-copulatory selection
Authors: Bhave Rachana S , Seears Heidi A , Reedy Aaron M , Wittman Tyler N , Robinson Christopher D , Cox Robert M
Published: December 2023

In promiscuous species, fitness estimates obtained from genetic parentage may often reflect both pre- and post-copulatory components of sexual selection. Directly observing copulations can help isolate the role of pre-copulatory selection, but such behavioral data are difficult to obtain in the wild and may also overlook post-copulatory factors that alter the relationship between mating success and reproductive success. To overcome these limitations, we combined genetic parentage analysis with behavioral estimates of size-specific mating in a wild population of brown anole lizards (Anolis sagrei). Males of this species are twice as large as females and multiple mating among females is common, suggesting the scope for both pre- and post-copulatory processes to shape sexual selection on male body size. Our genetic estimates of reproductive success revealed strong positive directional selection for male size, which was also strongly associated with the number of mates inferred from parentage. In contrast, a male’s size was not associated with the fecundity of his mates or his competitive fertilization success. By simultaneously tracking copulations in the wild via the transfer of colored powder to females by males from different size quartiles, we independently confirmed that large males were more likely to mate than small males. We conclude that body size is primarily under pre-copulatory sexual selection in brown anoles, and that post-copulatory processes do not substantially alter the strength of this selection. Our study also illustrates the utility of combining both behavioral and genetic methods to estimate mating success to disentangle pre- and post-copulatory processes in promiscuous species.

Published: December 2023

This study investigated epigenetic changes, specifically epigenetic ageing, in an adult cohort of healthy individuals using five validated epigenetic clock algorithms and a DNA methylation-based estimator of telomere length. Our study demonstrated significant biologic/epigenetic age dysregulation in sun-exposed vs. sun-protected dermal and epidermal skin, with a strong correlation to the validated Helfrich skin photoageing scale, occurring in patterns that overlap with those seen in basal cell carcinoma. This work highlights the power of novel epigenetic analyses in studying photoageing and skin cancer predisposition.
Leisure Engagement and Self-Perceptions of Aging: Longitudinal Analysis of Concurrent and Lagged Relationships
Authors: Bu Feifei , Mak Hei Wan , Bone Jessica K , Gao Qian , Sonke Jill K , Fancourt Daisy
Published: December 2023

Objectives

There is evidence to suggest that leisure engagement may influence self-perceptions of aging, but disentangling potential bidirectionality in this relationship is challenging. A better understanding of the directionality of this association is essential for designing more effective interventions to promote healthy aging. We, therefore, tested concurrent effects and lagged effects in both directions for a univariate measure of leisure engagement as well as specific domains of community, cognitive, creative, and physical activities.

Methods

A total of 17,753 adults aged 50 or above living in the United States from the Health and Retirement Study were included in the analysis. They provided 32,703 observations over 3 waves between 2008/2010 and 2016/2018. Data were analyzed using structural equation modeling with both concurrent and lagged associations between self-perceptions of aging and leisure engagement, controlling for confounders including age, gender, ethnicity, socioeconomic position, and health conditions.

Results

We found consistent evidence for leisure engagement as a predictor of self-perceptions of aging. There was also evidence for a reciprocal relationship where leisure engagement was predicted by older adults’ self-perceptions of aging. Similar results were observed for specific domains of leisure engagement.

Discussion

Our findings provide empirical support for the potential benefits of leisure engagement on positive self-perceptions of aging, regardless of the type of activities. Our study also highlights the importance to consider the directionality in researching leisure engagement and self-perceptions of aging.
The Potential of Informal Care for Self-Perceptions of Aging Among Older Community-Dwelling Adults: Longitudinal Findings From the Health and Retirement Study
Authors: Zwar Larissa , König Hans-Helmut , Hajek André
Published: December 2023

Objectives

This is the first study to analyze, whether receipt of (informal) care with (instrumental) activities of daily living (IADL/ADL) is associated with (positive and negative) self-perceptions of aging among community-dwelling older adults; and whether chronological age moderates these associations, using a longitudinal design.

Methods

Longitudinal data of the Health and Retirement Study in the United States was used. The sample was composed of up to 9,198 observations of community-dwelling adults aged ≥50 years pooled over 6 waves (2008–2018). Receiving care at all and the amount of care received with (I)ADL were analyzed in association with positive and negative attitudes towards own aging (ATOA; 8-item modified Philadelphia Geriatric Center Morale Scale, positive and negative subscore). Adjusted fixed effects regression analyses with robust standard errors were calculated.

Results

Transitioning into receipt of care with any (I)ADL was associated with lower positive ATOA but not with any change in negative ATOA. Chronological age moderated the association between receipt of informal care, primarily with IADL, and negative ATOA. More negative ATOA was found among care recipients between 50 and 64 years but less among care recipients aged ≥80 years.

Discussion

Receiving any form of informal care was associated with an increase in internalized ageism, in particular among adults aged 50 to 64 years, but a decrease among those aged ≥80 years. Psycho-educative measures are recommended for adults with care needs to prevent a loss of positive self-perceptions of aging, and reduce the danger to their healthy aging, with the receipt of care.

Published: December 2023

Dementia-friendly communities (DFCs) aim to foster a supportive, inclusive and empowering environment that promotes equal rights and resources for people living with dementia and their care partners. Central to DFCs is promoting access and navigation of outdoor spaces and destinations in the neighbourhood. While there is a growing interest and uptake of DFCs in policy and practice, there is scarce empirical evidence on the role of the built environment on mobility and navigation for people living with dementia. The “Dementia-inclusive Spaces for Community Access, Participation, and Engagement (DemSCAPE)” study aims to identify spatial and temporal patterns in activities undertaken outside home by people living with dementia, and ways in which the neighbourhood built environment affects their outdoor mobility and social participation. A series of sit-down and video-and-photo-documented walk-along interviews were conducted with 26 participants who are living with (mild to moderate) dementia or mild cognitive impairment in the Metro Vancouver region of British Columbia, Canada. Findings shed light on how people living with dementia understand and navigate the neighbourhood environment, and features that prompt recall of routes, places, and events, and support orientation and wayfinding. Findings also underscore the importance of participants’ awareness of barriers and obstacles in their neighbourhood, and how they cope with challenges and demands encountered while walking outside. The study offers planners and designers awareness and insights into the lived experience of navigating the neighbourhood environment with the condition of dementia and guidance on adopting a dementia-friendly and inclusive approach in policy and practice.

Authors: Devi Reena , Haunch Kirsty , Dalkin Sonia , King Natalie , Bate Angela , Spilsbury Karen , Goodman Claire , Jones Liz
Published: December 2023

Introduction

increasing demand for care, high staff turnover and low numbers of new staff are causing significant staff shortages in the long-term-care (LTC) sector. Solutions need to 1) take the heterogeneity of organisational and staff characteristics into account, and 2) make use of the large volume of literature describing the reasons staff join and stay in LTC work. Our research aimed to develop strategies which attract, recruit and retain Registered Nurses and frontline care workers in LTC; explain how and why strategies are effective, for which staff, the conditions needed, and the costs involved.

Method

This realist review involved (i) co-developing strategies and initial programme theories, (ii) systematically searching the evidence to test IPTs and develop theoretical propositions, and (iii) validating and refining propositions with stakeholder groups.

Results

IPTs around the following strategies were rated as important for attracting, recruiting and retaining staff in LTC, and taken forward to the testing phase of our review: rewarding and recognising staff, offering flexible working, career development opportunities, enhanced salary package, welcoming and inducting staff, listening to and providing staff feedback, developing caring work environments and effective staff interviewing. Leadership, caring cultures, teamwork, resources and adequate staffing levels are important conditions which enable these strategies lead to positive outcomes.

Discussion

this is the first study to use a realist approach to developing strategies focused on attracting, recruiting and retaining the LTC workforce. Our findings will be relevant at an international level.

THE ASSOCIATION BETWEEN PERSON-CENTERED PLANNING AND PERSON-REPORTED OUTCOMES IN HOME- AND COMMUNITY-BASED SERVICES
Authors: Chong Natalie , Caldwell Joseph
Published: December 2023

Person-centered planning (PCP) allows home and community-based service (HCBS) users to plan and coordinate services and supports according to their preferences and needs. The extent to which HCBS systems provide high-quality PCP and evidence for the relationship between PCP and user outcomes is limited. This study examines HCBS user characteristics related to PCP and the association between PCP and both unmet need and community living. We used the 2018-2019 National Core Indicators-Aging and Disability survey’s Person-Centered Planning Module, collected among adult Medicaid HCBS users in 12 states (n = 6,924). Independent variables included two general PCP measures (one on decision-making and another on preferences and choices being reflected in service plans) and a PCP fidelity scale to assess the extent to which users’ most recent service planning meeting was person-centered. Outcomes included two measures of unmet need for services and three measures of community living (i.e., participation, control, and satisfaction). We examined user characteristics associated with PCP and used logistic regression models to assess the relationship between PCP and outcomes. About 85% of users reported they were fully involved in decision-making, 77% reported their preferences and choices were reflected in their service plan, and 57% had their most recent service planning meeting coded as “high fidelity” on the PCP fidelity scale. Each marker of high-quality PCP was consistently related to lower likelihood of unmet need and greater likelihood of experiencing each community living outcomes. Findings suggest high-quality PCP is important for meeting HCBS users’ needs and improving community living outcomes.
FORGING A PATH TO DEVELOPING AGE-FRIENDLY CITIES AND COMMUNITIES IN GHANA: ISSUES AND RECOMMENDATIONS
Authors: Asante Samuel , Karikari Grace
Published: December 2023

The World Health Organization in 2007 launched the Age-friendly Cities and Communities (AFCC) initiative in an effort to make cities around the world more attuned to the needs of older adults. While AFCC initiatives have mostly been undertaken in developed societies around the world, developing countries appear to be excluded in this effort, as there is little to show for in the quest to creating AFCC. One of such countries is Ghana, where the proportion of older adults is expected to increase exponentially in the next decade, thereby heightening the need for AFCC. Utilizing a multiple case study approach, this paper synthesizes the procedures and findings of 16 case studies from around the world published on the eight domains of WHO’s Age-friendly Cities Framework, to make a case for developing AFCC in Ghana. Five important considerations were identified as fundamental to the effort to developing AFCC in Ghana: 1. Strengthening traditional views/perceptions on aging and older adults; 2. Involving key players in age-friendly efforts; 3. Responding to the complex interplay of needs and demands of older adults; 4. Designing policies and social programs to stimulate and enable cities and communities in Ghana to become age-friendly; 5. Developing validated instruments to assess the age-friendliness of cities and communities in Ghana. Designing and implementing AFCC require long-term commitment and devoting considerable resources to the cause. The paper concludes by discussing a culturally-appropriate model and policy recommendations to facilitate the move toward building age-friendly communities and age-inclusive cities in Ghana.

Approximately 16% of older adults worldwide experience some form of elder abuse including elder family financial exploitation (EFFE), the unlawful transfer and theft of funds and property perpetrated by a family member. Power of Attorney (POA) arrangements, when constructed and executed properly, can be critical tools for protecting against such exploitation. This national research study examined family reports of EFFE using the Bronfenbrenner Ecological Framework to classify risk factors within the POA arrangement. Interviews were carried out with 31 family members within 24 families that had experienced EFFE. Using constructivist grounded theory analysis methods, the following themes related to risk factors were noted across EFFE stories about professionals involved in the EFFE situations: 1) Conflict of interest between attorneys and POA agents, 2) A perceived lack of competence of consulting attorneys; and 3) A lack of transparency around POA arrangements. Policy and education implications include the need to create legal requirements for transparency reporting and/or registration for POAs, strengthening legal ethics and EFFE training, and providing public education to families about the POA process and how to locate appropriately trained legal professionals.

Religiosity is a strong factor related to health in older adults, which could positively affect physical and mental health. We aimed to observe the association between sociodemographic and clinical factors and the religiosity level in older adults. This is a secondary analysis of the Brazilian Older-adults Health Longitudinal Study (ELSI-Brazil) run by Fiocruz Institute in 2015 using a national sample of older adults (60+ year-old) population. The dependent variable was “How much the religious faith give meaning to your life?” and the independent were: sociodemographic (age-group, sex, race, marital status, and scholarly) and clinical (auto perception of health and non-transmittable chronic diseases diagnose - NTCD) characteristics, tested by Chi-Square with p<0.05 significant level. The total sample accounted for 4,669 participants, 4,080 (87.4%) answered that faith gives a lot of meaning to their lives. This percentage was significantly higher in women (91.2% vs 81.8% in men, p=0.003), indigenous race (95%, p=0.003), lower scholarly (p<0.001) and better auto perception of health (p=0.021). NTCD significantly related to higher importance of religiosity were hypertension (88.3%), dyslipidemia (90.0%), angina (93.9%), arthritis (90.5%), osteoporosis (91.0%), depression (88.7%), and cancer (90.4%). Participants with Diabetes (86.1%), pneumopathies (85.9%), and Parkinson (86.7%) had significant lower levels of religiosity. Religiosity had a significant association with sex, race, scholarly, health auto perception and NTCD, including cancer. The results evidence the important role of religious faith in the Brazilian older adult’s health. We concluded that religion and spiritual approach should always be considered to older adults.

Authors: Newsham Tina , Montepare Joann
Published: December 2023

Across GSA member groups, we teach, train, and mentor in a variety of ways and for different purposes. Education is a tie that connects us across the Society. In this AGHE Presidential Symposium, representatives from the different GSA membership sections will discuss the educational needs of their members and share strategies they employ with their students, employees, mentees, and others to ensure the best preparation of the workforce. Researchers, care providers, educators, advocates, and others must be well-prepared to address the opportunities and demands of an aging society. Tamar Shovali, from Behavioral and Social Sciences, will present empirically supported approaches to intergenerational communication and training to foster relationships between aging individuals and their communities. Biological Sciences member LaDora Thompson will highlight current educational efforts in translating geroscience discoveries into new medical advances. Health Sciences member Matt Peterson will present strategies, challenges and opportunities learned from a currently funded health sciences mentoring program. Social Research, Policy, and Practice member Nancy Kusmaul will discuss efforts to shape policy to enhance geriatrics and gerontology education. AGHE Chair Joann Montepare will serve as discussant, exploring how AGHE can build more bridges by integrating educational efforts in several unique ways. Collectively, presenters in this session will highlight the connections and opportunities for collaboration across GSA member groups.

Research shows gender differences in anxiety. Given that men and women have different levels of out-of-home activity and out-of-home activity is associated with anxiety, this study examines if gender differences in anxiety are mediated by out-of-home activity among older adults. The prospective cohort study enrolled 303 women and men aged 65 to 95 years old in central Massachusetts (2018-2020). Anxiety was evaluated by the Beck Anxiety Inventory. The out-of-home activity was measured by the percentage of daily step counts outside the home, which was objectively assessed by accelerometer and Global Positioning System devices. Data were analyzed by using mediation analysis, controlling demographic (age, race/ethnicity), physical health (self-rated health, comorbidities), and mental health (depressive symptoms, perceived stress). Results showed that women reported significantly greater scores in anxiety and did less out-of-home activity than men. Furthermore, out-of-home activity was significantly associated with anxiety. With the bootstrapping procedure, a significant indirect effect of gender on anxiety through out-of-home activity was shown (indirect effect: 0.025; 95% CI: 0.002-0.078), which explained 12% of the total effect (total effect: 0.214; 95% CI: 0.032-0.396). In conclusion, out-of-home activity partially mediates gender differences in anxiety. This study indicates that increasing out-of-home activities may help reduce anxiety and gender differences in anxiety among older adults.
A CROSS-COUNTRY ANALYSIS OF COGNITION AND ASSOCIATED RISK FACTORS

Published: December 2023

The widely cited Lancet Commission (Livingston et al., 2017) concluded that a third of dementia cases may be preventable through appropriate interventions targeting what they refer to as modifiable risk factors. These risk factors have been widely studied individually, but rarely investigated collectively and across many countries. We analyze the cross-country consistency of relationships between these modifiable risk factors and cognition using an internationally comparable set of aging studies in 31 countries including the United States, England and Europe. Cross-country differences in culture, policies, economy, and other collective experiences lead to significant variation in lifecycle outcomes, including dementia onset and modifiable risk factors. We find a limited number of robust relations: education, depression, and hearing show clear, consistent associations with our cognition measure, the sum of immediate and delayed recall. The evidence for other factors, including obesity, smoking, diabetes, and hypertension is weaker and becomes almost non-existent when correcting for multiple hypotheses testing. The inconsistent relationship across countries between these risk factors and cognition suggests the lack of a causal mechanism leading to cognitive decline – a necessary condition for these risk factors to be modifiable and effective targets for policy interventions aimed at controlling the prevalence and cost of dementia.

DIFFERENCES IN MEDICARE RESOURCE USE BY ENGLISH PROFICIENCY

Published: December 2023

Medicare is complicated and coverage decisions can be complex. Accordingly, the Centers for Medicare & Medicaid Services (CMS) provides a hotline, handbook, and website to help Medicare beneficiaries understand their benefits and coverage options. In this study, we used 2016-2018 Medicare Current Beneficiary Survey data and linear probability models to assess whether the likelihood of CMS Medicare resource use differed between beneficiaries with English proficiency and those with limited English proficiency (LEP). Our primary outcome was an indicator of having used at least one CMS resource. We considered English proficiency in both speaking and reading. Limited English-speaking proficiency or, separately, limited English-reading proficiency signified that the beneficiary reported speaking or reading English “not well” or “not at all.” Among a nationally representative sample of noninstitutionalized Medicare beneficiaries, 5.7% had limited English-speaking proficiency, 8.7% had limited English-reading proficiency, and 67.0% had used a CMS resource. Adjusting for health and social factors, age, language spoken at home, county-level Medicare Advantage characteristics, and state and year fixed effects, beneficiaries with limited English-reading proficiency were 16.7 percentage points less likely to have used a CMS resource compared to beneficiaries who reported reading English “well” or “very well” (p <.001). Limited English-speaking proficiency was not associated with CMS resource use. These findings have implications for federal initiatives to improve language access in Medicare, particularly efforts to reduce literacy barriers. Differences in Medicare coverage choice and benefits utilization among beneficiaries with LEP may be partially explained by differential access to or engagement with written CMS Medicare information.
