COPING STRATEGIES AND MENTAL HEALTH OF THE LGBTQ WITH HIV/AIDS – A SYSTEMATIC REVIEW
Authors: Ahmad Muhammad Ashraff , Mohamad Nor Azmawaty , Abd Hamid Harris Shah , Jamaludin Anne Noor Sri Juwaneeta
Published: November 2021

Facing stigma on both HIV and sexuality by the larger society puts significant pressure and stress on the LGBTQ living with HIV to cope with their diagnosis. The promotion of coping strategies as an intervention to increase well-being among PLHIV needs to consider current findings to remain relevant. This systematic review took 17 articles from 2008 to 2018 to provide a comprehensive analysis of issues that influenced coping strategies and investigate the association of the chosen coping strategy with their mental health. The results indicated that the impact of double stigma amplifies the challenge faced by the LGBTQ community to deal with their HIV diagnosis and had a significant impact on their mental health wellbeing. Both positive and negative coping styles were present as coping strategies employed with positive coping being used more as a chosen strategy. Each presenting coping strategy was reviewed, with depression and anxiety becoming the baseline indicator to reflect mental health status. This systematic review also revealed that the positive coping strategy does not necessarily lead to a positive psychological state as it is dependent on the changeability of the stressor faced. The findings emphasized the complexities in untangling the influence of coping on wellbeing among PLHIV. More attention should be paid to the mechanisms of stressor appraisal in selecting a more suitable coping strategy.

Published: November 2021

The study focuses on emerging adulthood and the transition to adulthood in Bulgaria, a topic that is rarely studied in the country. The participants were 233 students aged 18-30. Indicators such as criteria for the transition to adulthood, developmental features, and perceived adult status are examined. The results confirm the presence of a specificity that highlights a period of emerging adulthood in Bulgaria. More than two-thirds of the sample is perceived as emerging adults. The most preferred criteria for the transition to adulthood is Starting a family, and the least preferred Chronological age. Identity and Opportunities / Experimentation are the most valued as dimensions of maturity during the emerging adulthood period. Similarities with data from other studies within EU countries have been identified and discussed.

Published: November 2021

The article considers the results of an estimation of the shortwave radiation flux at the surface in Morocco from 2021-2050. Average monthly values of shortwave radiation coming to the underlying surface (Surface Downwelling Shortwave Radiation, RSDS), calculated using 11 regional climate models of the CORDEX-Africa project, were used as input data. The model calculation was performed assuming a greenhouse gas concentration scenario of RCP4.5. The aim of the work is to determine the characteristics of the distribution of shortwave radiation over the territory of Morocco from 2021-2050 and to identify areas with favourable conditions for developing solar energy in the near future. The results of an analysis of annual RSDS values in the vicinity of the solar power station in Ouarzazate in 2021-2050 are also presented.

Published: November 2021

The objective of this research is to assess the bioclimate of the city of Kharkiv in the summer season using the human thermal index of physiologically equivalent temperature (PET). The RayMan model has been used to obtain PET values. The results suggest that most days in Kharkiv during the summer are characterized by heat stress of various intensity 65.7% in June, 84.6% in July, 77.1% in August. The average frequency of comfortable weather is very low, varying from 12.6 to 25%. During heat waves, the frequency of days in Kharkiv with heat stress increases significantly, amounting to 96.3%. The results of the Kharkiv bioclimate assessment using PET may be used to create measures for heat adaptation and develop infrastructure for recreation and tourism in the city during hot periods.

Interstellar extinction in two concentric square areas of the sizes 1.25 × 1.25 deg2 and 0.2 × 0.2 deg2 in the direction of open cluster King 7 is investigated applying two-dimensional photometric classification of stars observed in the Vilnius seven-color photometric system down to V = 15.5 mag (1084 stars) and 19.5 mag (584 stars), respectively. The cluster members (284 stars) are identified applying their coordinates, proper motions, and parallaxes taken from the Gaia EDR3 catalog. New parameters of the cluster (distance, diameter, interstellar extinction, and age) are obtained. Photogeometric distances of stars are taken from Bailer-Jones et al. (2021) based on the Gaia parallaxes from EDR3. Physically the cluster is located at the outer edge of the Perseus spiral arm at d = 2.74 kpc, its diameter is 9.6 pc, the age is 175 ± 25 Myr, the earliest stars are of spectral classes B6–B7. The average interstellar extinction A

Probing the Nucleosynthetic Contribution of Low-metallicity, Low-mass Star Companions of CEMP Stars*
Authors: Shejeelammal J. , Goswami Aruna
Published: November 2021

The observed abundance diversities among CEMP stars can shed light on the formation and evolution of elements in the early Galaxy. In this work, we present results obtained from a detailed abundance analysis of a sample of seven extrinsic carbon stars. The analysis is based on high-resolution spectra obtained with HCT/HESP (R∼60,000) and SUBARU/HDS (R∼50,000). We present, for the first time, the elemental abundance results for the objects BD−19 132, BD−19 290, HE 1304−2111, HE 1354−2257, and BD+19 3109. Abundances of a few elements are available in the literature for HE 1157−0518 and HD 202851; we present an update on the abundances of these elements along with new abundance estimates for several other elements. Our analysis confirms the object HD 202851 to be a CH star. While BD−19 132, HE 1354−2257, and BD+19 3109 are found to be CEMP-s stars, the objects BD−19 290, HE 1157−0518, and HE 1304−2111 are found to belong to CEMP-r/s group. The observed abundance patterns of the three CEMP-r/s stars are well reproduced with the i-process model predictions. While the objects BD+19 3109 and HD 202851 are confirmed binaries, the binary status of the remaining objects is not known. Analysis based on different elemental abundance ratios confirms low-mass former AGB companions for all the objects. Kinematic analysis shows that BD−19 290, HE 1157−0518, HE 1354−2257, and BD+19 3109 belong to the Galactic halo, whereas BD−19 132, HE 1304−2111, and HD 202851 are members of Galactic thin disk.
Scaling of Small-scale Dynamo Properties in the Rayleigh–Taylor Instability
Authors: Skoutnev V. , Most E. R. , Bhattacharjee A. , Philippov A. A.
Published: November 2021

We derive scaling relations based on freefall and isotropy assumptions for the kinematic small-scale dynamo growth rate and amplification factor over the course of the mixing, saturation, and decay phases of the Rayleigh–Taylor instability (RTI) in a fully ionized plasma. The scaling relations are tested using sets of three-dimensional, visco-resistive MHD simulations of the RTI. They are found to hold in the saturation phase, but exhibit discrepancies during the mixing and decay phases, suggesting a need to relax either the freefall or isotropy assumptions. Application of the scaling relations allows for quantitative prediction of the net amplification of magnetic energy in the kinematic dynamo phase and therefore a determination of whether the magnetic energy either remains sub-equipartition at all velocity scales or reaches equipartition with at least some scales of the turbulent kinetic energy in laboratory and astrophysical scenarios. As an example, we consider the dynamo in RTI-unstable regions of the outer envelope of a binary neutron star merger, and predict that the kinematic regime of the small-scale dynamo ends on the timescale of nanoseconds and then reaches saturation on a timescale of microseconds, which are both fast compared to the millisecond relaxation time of the post-merger.
Extreme Variability and Episodic Lifetime of Quasars
Authors: Shen Yue
Published: November 2021

We constrain the average episodic quasar lifetime (as in steady-state accretion) using two statistics of quasars that are recently turned off (i.e., dimmed by a large factor): (1) the fraction of turned-off quasars in a statistical sample photometrically observed over an extended period (e.g., Δt = 20 yr) and (2) the fraction of massive galaxies that show “orphan” broad Mg ii emission, argued to be short-lived echoes of recently turned-off quasars. The two statistics constrain the average episodic quasar lifetime to be hundreds to thousands of years. Much longer (or shorter) episodic lifetimes are strongly disfavored by these observations. This average episodic lifetime is broadly consistent with the infall timescale (viscous time) in the standard accretion-disk model for quasars, suggesting that quasar episodes are governed by accretion-disk physics rather than by the gas supply on much larger scales. Compared with the cumulative quasar lifetime of ∼106−108 yr constrained from quasar clustering and massive black hole demographics, our results suggest that there are ∼103−105 episodes of quasar accretion during the assembly history of the supermassive black hole. Such short episodes should be clustered over intervals of ∼104 yr to account for the sizes of ionized narrow-line regions in quasars. Our statistical argument also dictates that there will always be a small fraction of extreme variability quasars caught in “state transitions” over multiyear observing windows, despite the much longer episodic lifetime. These transitions could occur in a rather abrupt fashion during non-steady accretion.

Published: November 2021

Spectropolarimetric efforts in the last few years have developed an efficient method that is based on the profiles of the polarization plane position angle of broad emission lines in active galactic nuclei. Here we present black hole measurements of SBS 1419+538 using spectropolarimetric observations in the Mg ii spectral band. The observations are performed by the 6 m telescope of the Special Astrophysical Observatory of the Russian Academy of Sciences (SAO RAS) using SCORPIO-2. We found good agreement for this object’s estimated supermassive black hole mass using spectropolarimetry compared with the mass obtained using other methods.

Published: November 2021

A new species ofOligodonFitzinger, 1826 is described based on specimens collected from Churah Valley of Himachal Pradesh. The new species is related toO. arnensisbased on molecular as well as morphological data, however differs from it in several aspects. The new species shows a pairwise sequence divergence of 6–20% from congeners for mitochondrial cytochrome b gene. Lack of pterygoid and palatine teeth of the new species suggests that the diet may largely comprise of eggs. Discovery of the new species is not surprising, as the Western Himalayas has been poorly explored in terms of its herpetofaunal diversity. Considerable genetic divergence in the sampled sequence suggestsOligodon arnensisis a species complex, likely represents multiple species and a revision of the group would be desirable.

Published: November 2021

A new species, Epeorus (Caucasiron) hyrcanicussp. nov., is described based on larval morphology and molecular data (COI) containing sequences from all Caucasian Caucasiron species described to date. The species is distributed in the Hyrcanian forest of southeastern Azerbaijan and northwestern Iran. Based on our wide-range sampling, the new species is likely endemic to this area. The most pronounced larval morphological diagnostic characters are the coloration pattern of abdominal sterna (a pair of oblique stripes and stripe-like medio-lateral maculae) and terga (triangular medial maculae), poorly developed projection of the costal margin of gill plates III, presence of hair-like setae on the surface of abdominal terga, and relatively wide shape of gill plates VII (in natural position from ventral view). The diagnostic characters are compared to related species, and primary information to habitat is provided.
Compétitivité externe décroissante et vulnérabilités : un besoin d’actions publiques résolues pour l’agroalimentaire
Authors: Guillou Marion , de Franclieu Hugues , Saint-Félix Claire
Published: November 2021

Que s’est-il passé depuis mai 2020 en matière de compétitivité du secteur agroalimentaire français [1] ? Les fondamentaux agronomiques ou économiques n’ont guère changé. La balance commerciale de la France dans ce secteur est toujours globalement excédentaire. Mais sa lente dégradation se poursuit. Le décrochage des parts de marché de la France par rapport à ses principaux concurrents européens est manifeste. Les différents auteurs de cet article attribuent ce décrochage à un manque de « compétitivité » – qu’il s’agisse du coût du travail dans ce secteur, de la faiblesse de ses gains de productivité, de la compétitivité hors-prix ou de causes plus structurelles. Tous les acteurs ne s’accordent pas pour autant sur l’urgence à agir et les remèdes à employer. L’élément nouveau, depuis 2020, est que la « souveraineté alimentaire » est revenue dans les débats. « Déléguer notre alimentation est une folie », disait le Président de la République [2] au début de la crise liée à la Covid-19, alors que les supermarchés peinaient à fournir au rythme souhaité farine, lait ou œufs à des Français redécouvrant le plaisir de pratiquer la pâtisserie à domicile. Dès lors, la résilience de ce secteur devient une préoccupation, un fondement de l’action publique, et certains de ses intrants rejoignent la liste des « biens sensibles » [3].
Automated filtering in the nonlinear Fourier domain of systematic artifacts in 2D electrical impedance tomography
Authors: Alsaker Melody , Bladow Benjamin , Campbell Scott E. , Kar Emma M.
Published: November 2021

For patients undergoing mechanical ventilation due to respiratory failure, 2D electrical impedance tomography (EIT) is emerging as a means to provide functional monitoring of pulmonary processes. In EIT, electrical current is applied to the body, and the internal conductivity distribution is reconstructed based on subsequent voltage measurements. However, EIT images are known to often suffer from large systematic artifacts arising from various limitations and exacerbated by the ill-posedness of the inverse problem. The direct D-bar reconstruction method admits a nonlinear Fourier analysis of the EIT problem, providing the ability to process and filter reconstructions in the nonphysical frequency regime. In this work, a technique is introduced for automated Fourier-domain filtering of known systematic artifacts in 2D D-bar reconstructions. The new method is validated using three numerically simulated static thoracic datasets with induced artifacts, plus two experimental dynamic human ventilation datasets containing systematic artifacts. Application of the method is shown to significantly reduce the appearance of artifacts and improve the shape of the lung regions in all datasets.

Published: November 2021

It was shown that unbounded solutions of the Neumann initial-boundary value problem to the two-dimensional Keller–Segel system can be induced by initial data having large negative energy if the total mass $ \Lambda \in (4\pi, \infty)\setminus 4\pi \cdot \mathbb{N} $ and an example of such an initial datum was given for some transformed system and its associated energy in Horstmann–Wang (2001). In this work, we provide an alternative construction of nonnegative nonradially symmetric initial data enforcing unbounded solutions to the original Keller–Segel model.

Authors: Tański Tomasz , Matysiak Wiktor , Smok Weronika , Marta Zaborowska
Published: November 2021

Polymer nanocomposites with unique optical properties are currently one of the materials most desired by the industry. An effective method of producing this type of materials is the method of electrospinning from a solution or melted polymers, which allows to obtain a nanocomposite in the form of a mat composed of nanofibers. This paper describes the process of producing nanofibers from polyacrylonitrile (PAN) and composite thin nanofiber mats from PAN with the addition of graphene oxide (GO) particles using the electrospinning method. In addition, the aim of the work was to investigate the influence of process parameters and filler on the morphology and optical properties of the nanomaterial. By changing the configuration of the distance between the nozzle and the collector (10 and 20 cm) and keeping the remaining parameters of the electrospinning process constant, two PAN polymer samples and two PAN/GO composite samples were manufactured. The analysis of the chemical composition and morphology of the obtained materials was performed using X-ray microanalysis (EDX) and scanning electron microscopy (SEM), respectively. In order to examine the chemical structure of the polymer and composite nanofibers, Fourier-Transform Infrared Spectroscopy (FTIR) was used. The analysis of the optical properties and the energy band gap of the prepared nanofibers was determined by spectral analysis using a UV–Vis spectrophotometer. The research showed a significant influence of the filler on the morphology.

Published: November 2021

Photoelectrodes are key components of the dye-sensitized solar cells (DSSCs), and as such improving their properties, may lead to an overall improvement of the entire cell.This paper aims to fabricate and compare the properties of various photoanodes (resulting in DSSCs) to determine how the overall efficiency of the cell is affected by various additives mixed into the TiO2 paste deposited on fluorine-doped tin oxide (FTO) covered glass, thus changing the photoanode composition. The TiO2 paste has been previously mixed with various materials such as ZnO, SiO2, Pd, and carbon nanotubes (CNTs). Basing on the prepared photoanodes, DSSCs have been prepared and analyzed by UV-Vis spectroscopy and atomic force microscopy. Moreover, were tested on a SS I-V CT-02 laboratory stand equipped with a Photo Emission Tech SS150AAA solar radiation simulator and Keithley 2401 low-voltage multimeter. The test results allowed for a determination of their properties and comparison. The highest efficiency has been obtained for the DSSCs based on photoanodes with TiO2 (1.58%) and TiO2/ZnO (1.52%).

Background: Olfaction plays an important role in our daily and social lives, both as adults and as children. This study assessed whether the ability to identify odours increases with age, as well as the ability in various age groups and the factors involved. Methods: The survey was performed in 2017 on 697 Japanese children (366 girls and 331 boys) aged 6–18 years who lived in Tsunan, Niigata Prefecture, Japan by using the ‘Open Essence’, a card-type odour identification test. We collected information regarding age, sex, and physical characteristic. We also inquired whether participants had siblings or if members of the family smoked, and whether they had conversations about odour at home. Statistical analysis was performed to evaluate the factors affecting odour identification abilities. Results: The results showed that the odour identification abilities of children increase with age, and children who have daily conversations about odours at home have better odour identification abilities. Conclusions: Odour identification ability increases with age. In addition, our findings suggest that conversation may positively affect odour identification. Hence, it is important for children to be exposed to an environment where they develop an interest in smells for better growth of their olfactory identification ability.

There is a growing interest among policymakers and researchers in estimating the impact of systemic stress on the economy. In this chapter, I present main findings of a panel study designed to estimate the impact of systemic stress in the euro area on bilateral exports of goods. Using the gravity model of international trade in goods, I found that systemic stress in the euro area, measured by the Composite Indicator of Systemic Stress for the euro area, the new Composite Indicator of Systemic Stress for the euro area and the EURO STOXX 50 Volatility Index negatively affects bilateral exports of goods, which is consistent with my expectations.

Australia is a developed country with higher GDP per capita than Slovenia. In this context, it is of great interest to Slovenian exporters. Slovenian export to this market is growing, while imports lags behind. The price elasticity of Slovenian exports of goods to Australia is 0.9, while the income elasticity is 4.6. The price and income elasticities of goods from Australia are higher than the corresponding elasticities of Slovenian exports. Despite the higher price elasticity of Australian goods imported by Slovenia, according to the price elasticity of Slovenian exports to the Australian market, even with the same mutual price reduction the Slovenian surplus continues to rise as a result of its initial high level. Slovenian exports are also at risk of losing their potential position on the Australian market due to the intensive integration of Australia into trade partnerships with developed Pacific economies, particularly Japan and South Korea. The effect of these agreements on Slovenian exports has been growing over recent years.

This paper examines the impact of economic policy uncertainty in the United States on unemployment of black and white Americans before the COVID-19 pandemic/recession. Our evidence shows that a positive economic policy uncertainty shock leads to an increase in the unemployment rate for members of both racial groups, which is in line with our expectations. However, our evidence also shows that economic political uncertainty in the United States is affecting the unemployment rate of black Americans faster and more strongly.
Financialization revisited: the economics and political economy of the vampire squid economy
Authors: Palley Thomas
Published: November 2021

This paper explores the economics and political economy of financialization using Matt Taibbi's vampire squid metaphor to characterize it. The paper makes five innovations. First, it focuses on the mechanics of the ‘vampire squid’ process whereby financialization rotates through the economy, loading sector balance sheets with debt. Second, it identifies the critical role of government budget deficits for the financialization process. Third, it identifies the critical role of central banks, which are the lynchpin of the system and now serve as de facto guarantors of the value and liquidity of private sector liabilities. Fourth, the paper argues financialization imposes a form of policy lock-in. Fifth, it argues financialization transforms popular attitudes and understandings, thereby generating political support despite poor economic outcomes. In effect, there is a politics of financialization that goes hand-in-hand with the economics. The paper concludes with some observations on why mainstream macroeconomics has no equivalent construct to financialization and discusses the disquieting unexplored terrain that the economy is now in.

Social Perception of the Influence of Public Policies on the Residential Rental and Holiday Tourism Rental Markets
Authors: Urrestarazu Capellán Ricardo , Ollero José Luis Sánchez , Pozo Alejandro García
Published: November 2021

This work assesses the influence of generic public housing policies in Spain and specific public policies relating to vacation rental housing on residential rental costs in recent years from the perspective of people linked to residential housing rental and vacation rental housing. We used partial least squares structural equation modelling on the data obtained in a survey of 413 individuals with direct links to the fields of tourism and real estate. The results obtained by the model confirm the influence of the growth in holiday tourist housing and the implementation of public housing policies on rises in residential rent. These conclusions can inform public policy measures in the general area of housing and, specifically, in the area of holiday homes, toward reducing the impacts of certain factors on access to housing in the province of Málaga. The main contribution of this work is the direct collection of the opinions of people related to residential and tourist housing on the Costa del Sol.

Establishing ecological and social priorities for urban biodiversity conservation and their alignment through green infrastructure planning; a case study in Swindon, UK.
Authors:   , Wilshaw Jonathan
Published: November 2021

The increasing number of people living in towns and cities across the world places ever growing pressures on, and demands of urban ecosystems. Research indicates that a diminution in the extent, quality and associated functions of urban green networks as a result of development pressure risks decline in urban biodiversity and the potential human benefits to be derived from nature rich urban environments. Adopting a case study approach, this research investigates ecological and socio-cultural priorities for conserving urban biodiversity and how these perspectives align within the theoretical framework and practice of green infrastructure planning. In doing so the research adds to a limited but growing body of evidence that describes the vital contribution of urban biodiversity to place making and how related policy and practice could better respond. The research took place in Swindon, UK, a town undergoing continued expansion and regeneration. Broadleaf plantation woodlands, as a widespread habitat and ubiquitous component of the town’s urban landscape, provided the venue for concurrent ecological and ethnographic explorations of the biodiverse qualities of place. Field studies of the richness and abundance of woodland dwelling beetles ran alongside observation of, and interviews with residents via regular and extended participation in Swindon’s health walks groups. The findings add to previous research highlighting the significance of the intricate and interlacing network of open spaces forming much of urban green infrastructure as wildlife habitats. Critically, the research also reveals the ways and depths to which common-place ‘everyday’ nature encountered in such settings is embedded within residents’ sense of place. The findings imply that urban biodiversity conservation goals should place much greater emphasis on local, small and inter-connecting greenspaces often dismissed in planning policy and conservation practice. Establishing such goals within strengthened green infrastructure planning frameworks and founded on a broader definition of urban biodiversity to encompass socio-cultural dimensions, could realise substantial benefits for environmental, personal and societal well-being.
