ABSTRACT
The migration of adult children can have beneficial and adverse effects on the health outcomes of elderly parents left behind. This study examines the effects of adult children's migration on self-rated health and depression among older parents using Longitudinal Ageing Study in India (LASI) 2017-18 with 19,401 individuals aged 60 years or older. Binary logistic regression models were performed to determine the association of self-rated health and depression with adult-child migration status while adjusting for living arrangements and socioeconomic factors. Results show that 36 percent of older parents have at least one migrant child, and 35 percent are empty nesters. Older adults living with their children experience positive impacts on their physical and mental health. Our study reveals that empty-nested elderly have a higher prevalence of poor self-rated health and depression. Irrespective of migrant children, the availability of children in the household matters most regarding parents' health care, as our study suggests no significant difference in physical and mental health among left-behind and non-left-behind older parents. This study aims to draw policymakers' attention to the impact of adult children or youth migration on older parents' physical and mental health. To address this issue, policies should prioritize raising awareness among migrant children of older adults about the importance of maintaining frequent contact and visiting their aging parents.
ABSTRACT
We investigated the structural and energetic properties of nanoclusters and nanoalloys composed of group 13 elements (B, Al, and Ga) up to a cluster size of 12. We conducted a comprehensive benchmark analysis of density functional and post-Hartree-Fock methods to identify efficient and accurate approaches for studying these systems using our benchmark dataset (BAlGa16) consisting of sixteen dimers and trimers. We compared different density functionals and post-Hartree-Fock methods using bond length and binding energy as parameters. B2PLYP closely follows CCSD(T) for geometry optimization, while REVPBE, BPBE, and PBE show cost-accuracy balanced performances. MRACPF was used as the reference for benchmarking energies, with NEVPT2 being the most accurate method, followed by CCSD(T) and DLPNO-CCSD(T). M06 and range-separated hybrid functionals perform well. Based on a cost-accuracy analysis, we recommend M06/def2-SVP as the preferred method. Additionally, we explored the structural evolution of pure, binary, and ternary clusters of group 13 elements up to 12 atoms, uncovering global and local minima. Ga clusters exhibited more rectangular faces compared to the predominantly trigonal faces of B and Al clusters. Binary clusters showed B in center positions, while Ga preferred outer positions, confirming the higher cohesion of B. The most favorable size of binary clusters (12) exhibited similar compositions of Al and Ga atoms. Compositions with 16.67-40% B, 16.67-60% Al, and 20-50% Ga were estimated to have negative mixing energies, indicating their relative stability.
ABSTRACT
The planar pentacoordinate carbon (ppC) atom is theoretically established here in [XC7H2]2+ and [XSi2C5H2]2+, where X = Be and Mg, using density functional theory. Inclusion compounds with alkali and alkaline earth metal ions are identified with the monomer units of tricyclic C7H2 and Si2C5H2 isomers with a planar tetracoordinate carbon (ptC) atom. While all alkali and some alkaline earth metals (Ca2+, Sr2+, and Ba2+) stabilize the ptC isomer in both cases, Be2+ and Mg2+ ions form a bond directly with the ptC atom, thus making it a ppC atom. The theoretical binding energies computed at the PBE0-D3/def2-TZVP level of theory are â¼-9.68, -10.42, -5.85, and -5.47 eV for [BeC7H2]2+, [BeSi2C5H2]2+, [MgC7H2]2+, and [MgSi2C5H2]2+, respectively.
ABSTRACT
BACKGROUND: Vaccine hesitancy affects immunization programs worldwide and can impact vaccine coverage and fight against Coronavirus disease 2019 (COVID-19) too. OBJECTIVES: Primary objectives: To find out the magnitude of COVID-19 vaccine hesitancy among the Health Care Worker Parents (HCWPs), the reasons for vaccine hesitancy, and their perceptions regarding COVID-19 vaccination of their children. SECONDARY OBJECTIVE: To analyze the clinic-socio-demographic correlates of COVID-19 vaccine hesitancy among HCWPs. METHODS: This was a cross sectional descriptive study. Health care workers who are parents were invited to participate in the study. Details about COVID vaccination status, COVID-19 illness of HCWPS and family members and its outcomes , reasons for not getting vaccinated, willingness to vaccinate their children, reasons for not willing to vaccinate their children, their responses to vaccine hesitancy survey (VHS) questionnaire and Modified Oxford COVID-19 vaccine hesitancy scale (MOVHS) were collected and analyzed using descriptive statistics. RESULTS: A total of 269 HCWPs participated in the study. Of the HCWPs, 97% had completed their COVID-19 vaccination schedule. Majority stated that they would vaccinate their children when it is available. Although majority of the responses were positive or towards agreement, there were some striking variations in the responses among some sections of HCWPs. Positive responses to the questionnaire were associated with higher self-vaccination and a decision to vaccinate their children. CONCLUSION: Vaccine hesitancy was less common among HCWPs in our study. A section of the HCWPs might be disproportionately more hesitant than others. Majority were in favor of vaccinating their children.
