An In‐Situ‐Formed Copper‐Based Perfluorinated Catalytic System for the Aerobic Oxidation of Alcohols
Authors: Drymona Maria , Kaplanai Entzy , Vougioukalakis Georgios C. 
Published: January 2024

AbstractHerein, we report a new catalytic protocol for the aerobic oxidation of alcohols. The catalytic system is formed in situ, in a straightforward and user‐friendly manner, combining a widely available copper source (Cu2O) with one imidazolium salt precursor bearing perfluorinated moieties. Our protocol uses TEMPO, as additive, and the reaction takes place at the interface of a biphasic solvent system, consisting of anisole and 1‐bromoperfluorooctane. The as‐prepared carbonyl compounds remain in the organic solvent, while the catalytic system remains in the fluorous phase. In this manner, the isolation and purification of the desired products are quite facile. Our protocol uses low catalytic loadings and is more efficient with primary alcohols, affording the desired products in good to excellent yields. The fluorous phase containing the catalytic system can be efficiently recovered and reused for at least six times, without a significant decrease in its catalytic efficiency.

AbstractConsidering the cooperative willingness of multiple heterogeneous energy sources to participate in the alliance, the stability of the cooperative operation of each entity (hereinafter referred to as stability) and the supporting mechanism of its optimal combination to realize the high proportion of new energy generation are studied. Through simulating load peak‐cutting and valley‐filling in the power system, the difference between the load value and the base load in the 24 h of the daily load curve is used as the calculation condition for the supply balance of the alliance. Based on the source‐load power balance model, the feasibility of power data normalization is derived and demonstrated. Simultaneously, taking into account the time‐of‐use price cost of each entity, a multiscale operation cost allocation and stability evolution analysis model for the alliance is constructed using the Shapley value and the largest consistent set method. By comparing the willingness of each entity to engage in the alliance, as well as the multiscale operation stability and economic change rule of different alliances, the results demonstrate that: (1) Alliance 1 has the advantage of economic operation. (2) The common stability period of different alliances is influenced by the participation preferences of each entity (wind power, photovoltaic, and thermal power tend to participate in Alliance 1, while hydropower tends to participate in Alliance 2). (3) Alliance internal restructuring can be carried out by utilizing spatial and temporal difference characteristics of different entities’ participation in alliance preferences, thereby achieving alliance stability and efficient operation. This study provides a theoretical basis for making decisions regarding the optimized stable operation of the alliance.

Published: January 2024

AbstractCloud computing (CC) offers on‐demand computing and resources to users, and organizations, and is also used in many human‐centric intelligent systems. Attacks in cloud networks cause huge damage to service providers and users. Distributed Denial of Service (DDoS) is one of them that greatly impacts the cloud network. The unavailability of resources is the major concern pertaining to cloud service and resources. Apart from the direct targets of a DDoS attack, there are also indirect effects on non‐targets within a cloud network. These effects on the non‐target stakeholders of the cloud are called collateral damages. However, this area of research is not explored much by researchers. Thus, the defense methods pertaining to direct and indirect effects need to be explored. This article aims to describe the consequences of DDoS attacks and the solutions available in the cloud network. The novelty of this article lies in shedding light on the indirect impacts of DDoS in cloud networks and possible solution approaches. The article also provides a comparative analysis of the existing defense solution under different categories and available tools and datasets to evaluate the proposed solutions. The article also mentions the solution considerations and effective solution scenarios. The idea behind this article is to impart guidelines to the researchers, for developing efficient defense solutions against direct target and indirect target DDoS attacks. Moreover, the research shortcomings, pros–cons, and existing challenges are outlined, and directions for future research are mentioned.

Published: January 2024

AbstractIntroductionMild cognitive impairment (MCI) is a known risk factor for the development of dementia. The potential benefits on cognition from non‐pharmacological measures such as art‐based interventions are of increasing interest. This systematic review examines the evidence for the impact of one form of art‐based intervention, visual art therapy (VAT), on the cognition and psychological wellbeing of older people with MCI.MethodsRandomised controlled and quasi‐experimental trials evaluating the efficacy of VAT in older persons aged over 60 years with MCI were included. A search was performed on electronic databases: MEDLINE, CINAHL, Embase and PsycINFO. Joanna Briggs Institute critical appraisal and extraction tools were utilised for risk of bias assessment and data extraction, respectively. A narrative descriptive approach was used to outline the findings.ResultsSeven studies were identified from 4311 articles screened. Improvement in cognition was reported in five studies, with two of these reporting sustained improvement at 6–9 months, while the remaining three studies showed improvement only at the immediate post‐intervention period. A positive impact was reported in four of six studies that examined the effect of VAT on participant psychological wellbeing. The overall methodological quality of the studies ranged from moderate in four of five RCTs, to high in the quasi‐experimental studies and one RCT. However, the low study power in the context of small sample sizes limits the applicability of these studies to the population of interest.ConclusionsVAT is potentially an effective non‐pharmacological intervention that may enhance cognition and provide benefits for psychological wellbeing in older persons with MCI. Given the limited studies available, with the majority emerging over the last 5 years, further research is required to confirm these reported benefits, as well as to determine whether VAT impacts on the progression of cognitive decline in MCI.

Published: January 2024

AbstractObjectiveTo compare the number and severity of neuropsychiatric symptoms (NPS) and associated caregiver distress between those with and without a noted history of psychological trauma among those referred to a specialised national dementia NPS support service.MethodsThis was a 5‐year retrospective observational study of records from the Dementia Support Australia NPS support service. NPS were reported by formal or informal caregivers at service entry using the Neuropsychiatric Inventory Nursing Home version or Questionnaire version. A history of psychological trauma was recorded in the person's social or medical history and/or endorsed as a contributor to NPS by a trained dementia consultant after a comprehensive clinical review. Regression was used to examine the impact of a recorded history of psychological trauma on NPS severity and associated caregiver distress, controlling for age and sex.ResultsAmong 41,876 eligible referrals with dementia, 6% (n = 2529) had some reference in their records to a history of psychological trauma. Referrals with a recorded history of psychological trauma were rated with a higher rate of both NPS severity (mean = 12.0) and associated caregiver distress (mean = 16.5) at service entry than those without a recorded history of psychological trauma (means = 10.7 and 14.5, respectively). A recorded history of psychological trauma was associated with higher odds of psychotic symptoms, agitation/aggression, irritability, disinhibition, affective symptoms and night‐time behaviours.ConclusionsTraumatic stress symptoms may represent a neglected target for intervention to reduce the impact of NPS in people with dementia.
The new meaning of retirement for bridge employees: Situating bridge employment through the lens of the Kaleidoscope Career Model
Authors: Mazumdar Bishakha , Warren Amy M. , Brown Travor C. 
Published: January 2024

AbstractRetirees re‐entering the workforce, popularly termed as bridge employment, is a phenomenon that is anticipated to increase in the coming years. Though research establishes that these employees have unique aspirations and work motives (see Mazumdar et al., 2020), primary research on how the retirement transition and bridge employment shape each other is scarce. This is troubling because a better understanding of the aspirations and motives of potential employees is an important step in designing suitable employee development strategies. To fill this gap in the literature, our paper explores the significance of retirement for those retirees who engage in bridge employment. We also explore whether bridge employment is unique from pre‐retirement employment. We interviewed 26 bridge employees and analyzed their narrations using the thematic analysis method. We utilized the Kaleidoscope Career Model by Mainiero and Sullivan (2005) to contextualize our analysis. Our study reveals that bridge employees uniquely reconstruct the meaning of retirement as a frontier between “prioritizing the obligations” and “prioritizing self.” Our findings also demonstrate how this view allows retirees to prioritize self‐directed goals during bridge employment. Our paper enriches the human resource development literature on careers and retirement by examining it from the vantage point of bridge employees. We shed light on how re‐framing the narratives of retirement helps distinguish between bridge employment and pre‐retirement employment for retirees. Better understanding this distinction can help lay the foundation for crafting suitable employee development programs for improved motivation and retention.

AbstractBackgroundChronic health conditions were significantly correlated with an increased clinical severity of coronavirus 2019 (COVID‐19) and a heightened risk of COVID‐19 mortality. This study aims to determine global knowledge, attitudes, and practices (Knowledge Abuse Profile) of the patients with chronic diseases toward COVID‐19.MethodsThe study was initiated in December 2019 and extended until April 2023, during which an extensive search for relevant English‐language literature was conducted as part of this systematic review and meta‐analysis. Google Scholar, Scopus, PubMed/MEDLINE, Science Direct, Web of Science, EMBASE, Springer, and ProQuest were utilized for the search. The quality of included studies was assessed using a quality rating checklist created by Joanna Briggs Institute for cross‐sectional research. In the STATA software version 14, inverse variance and Cochran Q statistics were used for statistical analysis to assess heterogeneity among the studies. The Dersimonian and Liard random‐effects models were applied in cases where heterogeneity existed.ResultsA total of 23 studies involving 14,587 patients contributed to this meta‐analysis. These studies comprised 21 studies focused on knowledge, with 6864 participants, 12 studies on attitudes involving 3597 patients, and 12 on practices, encompassing 4126 patients. The pooled estimates for sufficient knowledge, positive attitudes, and COVID‐19 preventive behaviors among chronic disease patients were determined as 48.2% (95% confidence interval [95% CI]: 33.9%–62.5%), 60.8% (95% CI: 46.8%–74.8%), and 58.3% (95% CI: 39.5%–77.0%), respectively. Over the years, there was a consistent decrease in adequate knowledge, positive attitudes, and COVID‐19 preventive behaviors among the population. Specifically, regarding knowledge, the rates declined from 50.2% in 2020 to 49.7% in 2021 and dropped to 45.1%. Similarly, the percentage of individuals with a positive attitude fell, decreasing from 64.1% in 2020 to 60.3% in 2021 and dropping to 57.9% in 2022. Furthermore, COVID‐19 preventive behaviors showed fluctuations, with the rates recorded at 63.7% in 2020, increasing to 75.4% in 2021, and then decreasing to 47% in 2022, in line with the publication dates of included studies.ConclusionThe findings of meta‐analysis show a significant decrease in the levels of knowledge, attitudes, and adherence to preventative interventions for COVID‐19 among individuals with chronic diseases. The findings emphasize the need for targeted interventions, and ongoing education to address this trend.
Study of an unsteady magnetohydrodynamic‐free convective flow under parabolic ramped temperature and concentration in the presence of Soret and heat sink
Authors: Bormudoi Mridusmita , Ahmed Nazibuddin 
Published: January 2024

AbstractThe purpose of this paper is to investigate the effects of Soret, thermal radiation, and chemical reaction on an unsteady magnetohydrodynamic free convective flow past an impulsively initiated semi‐infinite vertical plate with heat sink under parabolic ramped temperature and parabolic ramped concentration. Using some nondimensional parameters, the flow boundary equations in this case are first converted to dimensionless equations. The closed‐form Laplace transform technique is employed here to solve the partial differential equations and get the solutions for fluid velocity, temperature, and concentration. The velocity, temperature, and concentration of the fluid tend to vary with the effect of various flow factors. These changes are graphically represented and analyzed. Differences in skin friction, Nusselt number, and Sherwood number for the different relevant parameters are also recorded. The Soret number hikes the fluid velocity and concentration. The rate of heat transfer, mass transfer, and momentum transfer improves due to the application of parabolic ramped conditions.

AbstractObjectiveThis research was conducted to assess access to assisted reproductive technologies (ART) and the current status of the in vitro fertilization (IVF) program that have been implemented in Indonesia over the last 10 years.MethodsWe established a retrospective cohort study and descriptive analysis of the current state of access to infertility care in Indonesia. The data were collected from all IVF centers, clinics, and hospitals in Indonesia from 2011 to 2020, including the number of IVF clinics, total ART cycles, retrieved fresh and frozen embryos, average age of IVF patients, IVF pregnancy rate, and causes of infertility.ResultsThe number of reported fertility clinics in Indonesia has increased from 14 clinics in 2011 to 41 clinics by 2020. As many as 69 569 ART cycles were conducted over the past 10 years, of which 51 892 cycles used fresh embryos and 17 677 cycles used frozen embryos. The leading cause of consecutive infertility diagnosis was male infertility. Nearly half of the women who underwent IVF procedures (48.9%) were under 35 years old. The pregnancy rate outcome of women who underwent IVF ranged from 24.6% to 37.3%.ConclusionDevelopments in ART in Indonesia have led to improvements in the ART cycles performed throughout the 10 year period. The identification of key areas that require improvement can provide an opportunity to enhance access to infertility care.

Published: January 2024

AbstractObjectiveTo assess the quality of life (QoL) in women following a maternal near‐miss event and to assess the women's attitude towards future fertility and their contraceptive choices.MethodsA cross‐sectional observational study was conducted in Government Medical College, Kozhikode, India among women who had experienced a near‐miss event (n = 50) between January 1, 2020 and May 31, 2021 during the peak of the COVID‐19 pandemic. The QoL was assessed using the WHO Quality of Life, BREF Version, questionnaire, which was administered to the consenting participants over phone. Information regarding desire for future fertility, contraceptive choices, and urogenital symptoms was also collected. A comparison between the short‐term and long‐term effects on the QoL was also done.ResultsA maternal near‐miss event was not found to adversely affect the overall quality of life in the present study. The scores in all the four domains—physical, psychological, social relationships, and environmental—suggested good QoL, although greater variability in values were observed in the physical and psychological domains. The influence in these two domains was more pronounced following a perinatal loss and following prolonged physical morbidities. There was no difference in short‐ and long‐term QoL following a maternal near miss (MNM). The MNM did not influence the contraceptive choices and there was no subsequent pelvic floor dysfunction in most women.ConclusionMNM was not found to adversely affect the overall subsequent QoL in the present study. There was no difference in short‐ and long‐term QoL following a MNM. Studies carried out over a longer period of time with a control group would yield more information.

AbstractObjectiveDuplex kidney is a relatively frequent form of urinary system abnormality. This study aimed to elucidate the value of chromosomal microarray analysis (CMA) and whole exome sequencing (WES) for duplex kidney and the perinatal outcomes of duplex kidney fetuses.MethodsThis retrospective cohort study included 63 patients with duplex kidney diagnosed using antenatal ultrasound between August 2013 and January 2023. We reviewed the clinical characteristics, genetic test results, and pregnancy outcomes of the patients.ResultsAmong the 63 cases based on the inclusion criteria, the CMA detected seven (11.1%) clinically significant variants and nine variants of uncertain significance (VUS), and the pathogenic/likely pathogenic (P/LP) copy number variations (CNVs) in the recurrent region that were associated with prenatal duplex kidney included 17q12, 17p13.3, and 22q11.2. No significant disparity was observed in the CMA detection rate between the unilateral and bilateral groups, or between the isolated and non‐isolated groups. WES identified three (50%) P/LP single‐gene variants in six fetuses with duplex kidney. We detected the following pathogenic genes in the duplex kidney fetuses: KMT2D, SMPD4, and FANCI. Pregnancy termination in cases where clinically significant variants were detected by genetic testing was different in statistical significance from that in cases with negative results (9/10, 90.0% vs 8/48, 16.7%, P < 0.001).ConclusionThis study elucidated the value of CMA and WES for fetal duplex kidney, proving that CMA and WES may be useful tools in prenatal diagnosis and genetic counseling.
Is lower fetal heart rate variability a susceptibility marker to the impact of negative coparenting on infant regulatory capacity?
Authors: Pinto Tiago Miguel , Figueiredo Bárbara 
Published: January 2024

AbstractLower fetal heart rate variability (FHRV) may be a prenatal endophenotypic susceptibility marker and increase the impact of both positive and negative coparenting on infant regulatory capacity. This study analyzed the moderator role of FHRV in the association between positive and negative coparenting and infant regulatory capacity at 3 months. The sample comprised 86 first‐born infants and their mothers and fathers recruited at a public Health Service in Northern Portugal. FHRV was recorded during routine cardiotocography examination at the third trimester of gestation. Mothers and fathers reported on coparenting and infant regulatory capacity at 2 weeks and 3 months postpartum. FHRV moderated the association between mother's and father's negative coparenting at 2 weeks postpartum and infant regulatory capacity at three months. Infants with low FHRV presented higher regulatory capacity when mothers or fathers reported less negative coparenting, while lower regulatory capacity when mothers or fathers reported more negative coparenting, than infants with high FHRV. Findings suggested lower FHRV as a prenatal endophenotypic susceptibility marker that increases the impact of negative coparenting on infant regulatory capacity.
