Increasing retirement ages in Denmark: Do changes in gender, education, employment status and health matter?
Authors: Amilon Anna , Larsen Mona 
Published: June 2023

AbstractRecent studies report significant increases in retirement ages over the past two to three decades in most countries in the Organization for Economic Co-operation and Development—increases that research has attributed mainly to changes in the legislative frameworks for retirement in these countries. Using unique data from the Danish Longitudinal Study of Ageing, this study investigates whether and, if so to what extent, changes to the workforce in terms of gender, education, employment status (employed or self-employed) and health contribute to explaining differences in retirement ages between the cohorts born in 1935 and 1950. The retirement window of these cohorts stretches from the early 1990s to the late 2010s—a period characterized by substantial changes to workforce. On average, retirement ages increased by two years from the 1935 cohort to the 1950 cohort. However, due to changes in the investigated factors having offsetting effects, the net effect of such changes on retirement ages was minor. Thus, while increasing levels of education and better health among older workers contributed to increasing retirement ages, increasing female labour force participation and fewer self-employed workers had the opposite effect. In absolute terms, the total compositional and behavioural influence on retirement ages of changes in terms of employment status (− 0.35 years) was almost as large as the total changes in terms of education (0.44 years). Thus, future studies investigating long-term changes in retirement ages would benefit from including changes in employment status (self-employed or wage earner) as an explanatory factor.

AbstractDepression is associated with key HIV-related prevention and treatment behaviors in sub-Saharan Africa. We aimed to identify the association of depressive symptoms with HIV testing, linkage to care, and ART adherence among a representative sample of 18–49 year-olds in a high prevalence, rural area of South Africa. Utilizing logistic regression models (N = 1044), depressive symptoms were inversely associated with reported ever HIV testing (AOR 0.92, 95% CI 0.85–0.99; p = 0.04) and ART adherence (AOR 0.82, 95% CI: 0.73–0.91; p < 0.01) among women. For men, depressive symptoms were positively associated with linkage to care (AOR: 1.21, 95% CI: 1.09–1.34; p < 0.01). Depression may adversely impact ART adherence for HIV-positive women and reduce the likelihood of HIV testing for women not aware of their HIV status which, in settings with high HIV prevalence, carries severe consequences. For HIV-positive men, findings suggest that depression may encourage help-seeking behavior, thereby impacting their health system interactions. These findings underscore the need for health-care settings to factor mental health, such as depression, into their programs to address health-related outcomes, particularly for women.

AbstractMetaverse is a new technology expected to generate economic growth in Industry 5.0. Numerous studies have shown that current bitcoin networks offer remarkable prospects for future developments involving metaverse with anonymity and privacy. Hence, modelling effective Industry 5.0 platforms for the bitcoin network is crucial for the future metaverse environment. This modelling process can be classified as multiple-attribute decision-making given three issues: the existence of multiple anonymity and privacy attributes, the uncertainty related to the relative importance of these attributes and the variability of data. The present study endeavours to combine the fuzzy weighted with zero inconsistency method and Diophantine linear fuzzy sets with multiobjective optimisation based on ratio analysis plus the multiplicative form (MULTIMOORA) to determine the ideal approach for metaverse implementation in Industry 5.0. The decision matrix for the study is built by intersecting 22 bitcoin networks to support Industry 5.0's metaverse environment with 24 anonymity and privacy evaluation attributes. The proposed method is further developed to ascertain the importance level of the anonymity and privacy evaluation attributes. These data are used in MULTIMOORA. A sensitivity analysis, correlation coefficient test and comparative analysis are performed to assess the robustness of the proposed method.

AbstractPesticide application can have an adverse effect on pollinator honey bees, Apis mellifera L., ranging from mortality to sublethal effects. Therefore, it is necessary to understand any potential effects of pesticides. The present study reports the acute toxicity and adverse effects of sulfoxaflor insecticide on the biochemical activity and histological changes on A. mellifera. The results showed that after 48 h post-treatment, the LD25 and LD50 values were 0.078 and 0.162 µg/bee, respectively, of sulfoxaflor on A. mellifera. The detoxification enzyme activity shows an increase of glutathione-S-transferase (GST) enzyme on A. mellifera in response to sulfoxaflor at LD50 value. Conversely, no significant differences were found in mixed-function oxidation (MFO) activity. In addition, after 4 h of sulfoxaflor exposure, the brains of treated bees showed nuclear pyknosis and degeneration in some cells, which evolved to mushroom shaped tissue losses, mainly neurons replaced by vacuoles after 48 h. There was a slight effect on secretory vesicles in the hypopharyngeal gland after 4 h of exposure. After 48 h, the vacuolar cytoplasm and basophilic pyknotic nuclei were lost in the atrophied acini. After exposure to sulfoxaflor, the midgut of A. mellifera workers showed histological changes in epithelial cells. These findings of the present study showed that sulfoxaflor could have an adverse effect on A. mellifera.

Abstract
Additional artificial ultraviolet-B irradiation (UV-B) is a substitute for the natural UV-B radiation, which is believed to modulate the antioxidants production in plants against the abiotic stress. The present research was formulated by using an indoor UV-B chamber, capable of irradiating UV-B at single wavelength of 315 nm on spearmint. In vitro destructive analysis revealed the reduction in accumulation of chlorophyll a and b as well as carotenoids. However, an elevated levels of phenolic index and total anthocyanins were recorded for both 43.2 KJ/m2 and 86.4 KJ/m2 UV-B doses. TBARS assay was carried out to record the lipid peroxidation in the spearmint and likewise, an enhanced secondary metabolites production, an increased lipid peroxidation was seen with the successive increased in the UV–B doses. A remarkable accumulation in the total sugars, reducing sugars and sucrose were also noticed. In vivo analysis revealed a decrease in chlorophyll estimated values as well as an increase of flavanols. Overall leaf fluorescence performance index was improved under both UV-B doses as well as the maximum quantum efficiency of photosystem II. Decreases in the total yield, plant height and length of internode was observed for both UV-B doses however, an enhanced number of stems was recorded for the 43.2 KJ/m2 UV-B dose. The results of present study not only provided a clear indication of the potential of UV-B in modifying the phytochemicals accumulation in plants but also opened a room for investigating various indoor UV-B doses for future studies of plants and their interaction towards UV-B.

Spherical SiO2 growth on LaFeO3 perovskite to create core–shell structures for Cd(II) adsorption on its surface
Authors: Arman M. M. , Ramadan Rania 
Published: June 2023

AbstractIn this study, LaFeO3 perovskite is synthesized by the flash method, and then a simple method is developed for growing SiO2 on its surface to construct a core/shell nanocomposite. The thickness of the SiO2 shell is controlled by varying the amount of tetra-ethyl orthosilicate (TEOS). Two LaFeO3@SiO2 samples with varying SiO2 thicknesses were synthesized. Herein, the lattice parameters, morphology, magnetic, and adsorption properties of the investigated core/shell nanocomposites are tuned by changing the content of SiO2. Results confirm that when the content of SiO2 increased, the prepared LaFeO3@SiO2 core/shell nanocomposite showed good adsorption performance, and the removal efficiency enhanced from 50 to 60% for LaFeO3 and LaFeO3@SiO2, respectively. It is thought that the enhancement of the adsorption performance is related to the high porosity and amorphous nature of SiO2.
Designing and Evaluating Relativity Lab: A Simulation Environment for Special Relativity Education at the Secondary Level

Published: June 2023

AbstractThis article describes the design and evaluation of a simulation environment for special relativity (SR) education at the secondary level. In recent years, SR has become increasingly popular in secondary school curricula worldwide. Because the key concepts in SR are very remote from everyday experience, they are difficult for students to learn. Computer simulations provide a promising approach to explore these abstract concepts in a simplified and idealized virtual environment. The currently available simulation tools for SR, however, are limited in terms of usability and flexibility. We report on the development of an online simulation environment, named Relativity Lab. In Relativity Lab, students can construct simulations themselves and freely select the inertial frame of reference from which the simulation is rendered. We performed a small-scale evaluation (N = 16) in which Relativity Lab was used in inquiry-learning activities. Results indicate that students found Relativity Lab a helpful tool for visualizing relative motion and relativistic light propagation. Moreover, the inquiry-learning activities helped students to recognize discrepancies between their prediction and the outcome of a simulation. We propose improvements to the current task design by providing stricter instructions with regard to constructing the simulation and switching between inertial frames.

Published: June 2023

AbstractBackground: Postoperative cognitive dysfunction (POCD) is a common clinical complication in elderly patients, but its underlying mechanism remains unclear. Receptor-interacting protein kinase 1 (RIPK1), a key molecule mediating necroptosis and regulated by transforming growth factor β-activated kinase 1 (TAK1), was reported to be associated with cognitive impairment in several neurodegenerative diseases. This study was conducted to investigate the possible role of TAK1/RIPK1 signalling in POCD development following surgery in rats. Methods: Young (2-month-old) and old (24-month-old) Sprague–Dawley rats were subjected to splenectomy under isoflurane anaesthesia. The young rats were treated with the TAK1 inhibitor takinib or the RIPK1 inhibitor necrostatin-1 (Nec-1) before surgery, and old rats received adeno-associated virus (AAV)-TAK1 before surgery. The open field test and contextual fear conditioning test were conducted on postoperative day 3. The changes in TNF-α, pro-IL-1β, AP-1, NF-κB p65, pRIPK1, pTAK1 and TAK1 expression and astrocyte and microglia activation in the hippocampus were assessed. Results: Old rats had low TAK1 expression and were more susceptible to surgery-induced POCD and neuroinflammation than young rats. TAK1 inhibition exacerbated surgery-induced pRIPK1 expression, neuroinflammation and cognitive dysfunction in young rats, and this effect was reversed by a RIPK1 inhibitor. Conversely, genetic TAK1 overexpression attenuated surgery-induced pRIPK1 expression, neuroinflammation and cognitive dysfunction in old rats. Conclusion: Ageing-related decreases in TAK1 expression may contribute to surgery-induced RIPK1 overactivation, resulting in neuroinflammation and cognitive impairment in old rats.
Reducing the vulnerability of tourists to tsunami: challenges for decision-makers

Published: June 2023

AbstractA near source or local tsunami, because of its close proximity to an affected area, cannot usually be predicted soon enough to mitigate many of the risks posed. The limited notice time in local tsunamis poses greater challenges for decision-makers than distant source tsunamis. Tsunamis affect coastal regions, where many of these areas are visited by tourists who often lack adequate knowledge of the hazards of the region. This study focuses on the risks tourists face during a local tsunami and discusses how to best protect tourists. Initially, a thematic literature analysis was performed to identify research gaps. Then, a case study methodology was adopted to obtain an in-depth understanding of how emergency management officials consider the management of tourists in evacuation planning. Napier, New Zealand, was used as a case study because it is a tourist town and vulnerable to tsunamis. Key decision-makers in the disaster management and tourist management sector were interviewed. The results outline three major initiatives that could lead to better tourist management and create better tsunami awareness for tourists. First, the risks posed to tourists can be reduced if emergency management officials collaborate with tourism agencies. Second, developing accurate evacuation simulations can show what would happen to tourists in a tsunami so that emergency management officials can be better prepared, and councils can improve evacuation planning and infrastructure to evacuate tourists and local communities safely. Third, educating tourists about evacuation plans will increase their readiness and enhance their safety.

Published: June 2023

AbstractPlasma in hydrogen-containing atmospheres is an efficient method for the reduction of iron oxides. Although a vast number of approaches were performed for the reduction of bulk Fe oxides with thermal hydrogen plasmas, there is almost no information about the non-thermal plasma reduction efficiency in the atmospheric pressure range. In the current article we present the reduction of natively oxidized iron surfaces applying a dielectric barrier discharge plasma in an Ar/H2 atmosphere at 1000 hPa. By varying the surface temperature from 25 to 300 °C, we studied the plasma reduction efficiency, which was then compared with a thermal method. Whereas plasma treatments at 25 °C and 100 °C did not result in the significant reduction of iron oxidized species, experiments at 200 °C and 300 °C yielded a reduction of approximately 88% and 91% of initial oxidized components already after 10 s, respectively. Moreover, we observed an increase in the efficiency with a plasma-thermal reduction in comparison to a thermal method, which was attributed to the presence of atomic hydrogen in the plasma phase. Analysis of morphology revealed the formation of Fe–C structures on surfaces after thermal and plasma-thermal treatments at 200 °C and 300 °C that may be connected with the diffusion of bulk contaminations to the deoxidized surface and reactions between the reduced Fe with plasma-activated adventitious carbon. Conclusively, the plasma was characterized by analyzing the reactive species and the electron temperatures.
Development and validation of a Medication Adherence Universal Questionnaire: the MAUQ
Authors: Cabral Ana C. , Lavrador Marta , Castel-Branco Margarida , Figueiredo Isabel Vitória , Fernandez-Llimos Fernando 
Published: June 2023

Abstract
Background
Different questionnaires assess self-reported medication adherence and others quantify aspects of patients attitudes towards medication, but not together in a single instrument. Gathering these two aspects in a single instrument could reduce patients survey burden.

Aim
The aim of this study was to develop the Medication Adherence Universal Questionnaire (MAUQ) using the Maastricht Utrecht Adherence in Hypertension short version (MUAH-16) factorial structure as the hypothesized model.

Method
A multistep process started with the modification of the MUAH-16 to obtain the MAUQ. Patients using at least one antihypertensive medicine were recruited. The two questionnaires, the MUAH-16 and MAUQ, were applied. A confirmatory factor analysis (CFA) was performed using the initial MUAH-16 s-order 4-factor model. An additional bifactor model with four uncorrelated factors and an overall score was tested. The comparative fit index (CFI), root mean square error of approximation (RMSEA) with confidence intervals (CIs), and standardized root mean squared residual (SRMR) were used to assess both models.

Results
A sample of 300 hypertensive patients completed the instruments. The CFA with the second-order 4-factor solution resulted in similar results for the MUAH-16 and MAUQ: CFIs of 0.934 and 0.930, RMSEAs of 0.043 [CI 0.030–0.056] and 0.045 [CI 0.031–0.057] and SRMRs of 0.060 and 0.061, respectively. The CFA with the bifactor model showed slightly better results for both the MUAH-16 and MAUQ: CFIs of 0.974 and 0.976, RMSEAs of 0.030 [CI 0.005–0.046] and 0.028 [CI 0.001–0.044], and SRMRs of 0.043 and 0.044, respectively.

Conclusion
CFA demonstrated that the MAUQ presented a better fit to both models than the MUAH-16, obtaining a robust universal free instrument to assess medicine-taking behaviour and four medicine beliefs components.

Published: June 2023

Abstract
Background and aims

Tree species worldwide suffer from extended periods of water limitation. These conditions not only affect the growth and vitality of trees but also feed back on the cycling of carbon (C) at the plant-soil interface. However, the impact of progressing water loss from soils on the transfer of assimilated C belowground remains unresolved.

Methods
Using mesocosms, we assessed how increasing levels of water deficit affect the growth of Pinus sylvestris saplings and performed a 13C-CO2 pulse labelling experiment to trace the pathway of assimilated C into needles, fine roots, soil pore CO2, and phospholipid fatty acids of soil microbial groups.

Results
With increasing water limitation, trees partitioned more biomass belowground at the expense of aboveground growth. Moderate levels of water limitation barely affected the uptake of 13C label and the transit time of C from needles to the soil pore CO2. Comparatively, more severe water limitation increased the fraction of 13C label that trees allocated to fine roots and soil fungi while a lower fraction of 13CO2 was readily respired from the soil.

Conclusions
When soil water becomes largely unavailable, C cycling within trees becomes slower, and a fraction of C allocated belowground may accumulate in fine roots or be transferred to the soil and associated microorganisms without being metabolically used.
Fibre optic-VLC versus laser-VLC: a review study

Published: June 2023

AbstractThe exponential increase in the demand for a fast and reliable wireless mobile network motivates the need for researchers to engage more actively in visible light communication (VLC) technology. This increase happens in parallel with the augmentation of the population to be accommodated. As a result, the radio frequency spectrum is overcrowded. VLCs, which are part of optical wireless communications, are unregulated ultra-wideband spectrums that offer an alternative to solve RF bandwidth exhaustion. The OWC has demonstrated, among others, a throughput of 100 Gbps and is capable of offloading large data traffic from RF networks. One of the VLC main backdrops is the distance for which light signals can be transmitted, which is generally short in nature. However, this is overcome by its combination with other technologies, such as fibre optics (FO) and laser technologies, to mention only a few, which form a cascaded system with VLC. The data offloaded is fed to the cascaded system of FO-VLC and laser-VLC. In this paper, we provide a comparative review of cascaded FO-VLC and laser-VLC systems. We survey the technology that can provide optimized communication and high bandwidth. The choice of cascaded system to be used or considered is dependent on the area of application. A comparison is conducted from the simulated results of both cascaded systems considering parameters such as the gain and throughput. The FO-VLC cascaded system shows that system gain always decreases as distance increases for a range of reflection coefficient,$$\rho$$ρ, and slightly decreases with attenuation coefficient,$$\alpha$$α. The gain of the laser-VLC cascaded system decreases with an increase in transmission distance for a given range of floor and ceiling reflection coefficient and decreases slightly with attenuation intensity,$$\gamma$$γ. From our investigation, it is clear that FO-VLC and laser-VLC are outstanding optical cascaded systems, which can be exploited in applications with a harsh environment. This research also highlights standardization efforts, advanced modulation schemes and coding techniques so far for VLC, FO and laser system and their promising applications.
