Nexus between stock markets, economic strength, R&D and environmental deterioration: new evidence from EU-27 using PNARDL approach
Authors: Mushafiq Muhammad , Prusak Błażej 
Published: December 2022

AbstractThis research investigates the impact of stock market indices, economic strength, and research and development expenditures on environmental deterioration in the EU-27 countries for the period 2000–2020. This study utilized linear and non-linear panel ARDL to estimate the short- and long-run effect. According to the results, the stock market indices have negative effect on environmental deterioration in the symmetric form. However, the asymmetric evidence shows that in the long run the positive shocks of stock market indices contribute positively to the environmental deterioration and negative shocks decrease the environmental deterioration. This effect is reversed in the short run. Linear effect of economic strength on environmental deterioration is positive. For non-linear effect, the long-run shocks show no difference. However, the negative shock of economic strength in the short run causes an increase in the environmental deterioration. Symmetric evidence for research and development increases environmental deterioration. However, asymmetric results show weak evidence. The study has policy implications in context of achieving sustainable development goals.

AbstractCorydalissaxicola Bunting, a medicinal herb known for alkaloids, grows mainly in Guizhou province and northwest Guangxi province of China. In this study, for the first time for this plant, an efficient adventitious shoot proliferation and regeneration system via shoot organogenesis from leaf and petiole explants was established. Cytokinins, including 6-benzyladenine (BA) and thidiazuron (TDZ), induced callus and then shoot organogenesis. Most adventitious shoots were induced from leaf explants on Murashige and Skoog (MS) medium (pH 6.5) supplemented with 2.0 µM BA and 0.5 µM α-naphthaleneacetic acid (NAA). This medium was also optimal for shoot proliferation. The rooting ½MS medium was supplemented with 1.0 µM indole-3-butyric acid (IBA) and 0.2 µM NAA; 95.7% of shoots induced roots within 30 d and 91% of plantlets survived on a peat:vermiculite (1:1, v:v) substrate after 90 d.

Authors: Pietryka Mirosława , Richter Dorota , Podlaska Magda 
Published: December 2022

AbstractGenus Wolfia Horkel ex Schleiden (Araceae, former Lemnaceae) includes 11 species that are the smallest of known flowering plants. The genus is widespread in the world. In Europe, the only native species is Wolffia arrhiza. In Poland, it is considered to be relatively rare and until the end of the 20th century it was known from small number of populations dispersed throughout the country Poland. Our research focused on Lower Silesia population of Wolffia arrhiza. The study included the verification of historical sites of this species known from the literature and an inventory of the contemporary occurrence. It also aimed to explain the pattern of W. arrhiza occurrence in selected habitats and determine the ecological conditions and phytocoenoses of the reservoirs it inhabits. The research of the species showed extinction of historical sites and the current presence in 12 water reservoirs of different origin, size, depth and management method. The share of W. arrhiza in phytocoenosis patches in the individual reservoirs is very diverse and ranges from 15 to 80%. Presented data supplement the information on the occurrence of W. arrhiza in western Poland as well as provide new information on its biology and ecology.

Published: December 2022

AbstractWe have focused on mixed halide perovskite thin films of the formula CsPbX3 where (X3 = Br3, Cl3, I3, Br2Cl, Br2I, and I2Cl) prepared by spin-coating in order to study the effects of partial and total Br substitution. For this purpose, we performed a series of characterizations, including x-ray diffraction, scanning electron microscopy (SEM), atomic force microscopy (AFM), and UV–visible spectroscopy. All the films except CsPbI2Br showed two characteristic peaks at 2θ angles of 26.80° and 51.80° corresponding to the (111) and (220) crystallographic planes. In the case of CsPbI2Br, we have the same peaks, but the main ones are located at 15° and 30° for the (100) and (200) planes, respectively. SEM examined the surface morphology of the different mixed lead halide films; the best surface was that of the CsPbBr2I sample, which is well-coated, dense, with no pinholes and no cracks, and has the largest grain size. In addition, all the mixed halide films showed good absorbance, especially between 600 nm and 900 nm, with band gap values between 1.94 and 2.92 eV.

Abstract
Background
Replacement of thyroid hormones (TH) with Levothyroxine (LT4) is the treatment of choice for hypothyroidism, however, there are aspects of treatment where uncertainties exist and practice varies. Factors influencing initiation and choice of TH replacement may impact patient satisfaction, safety, and health care costs.

Methods
The aim of the study was to examine the attitudes of Irish endocrinologists regarding the treatment of hypothyroid and euthyroid patients with TH. Members of the Irish Endocrine Society (IES) were invited to participate in an online survey.

Results
Forty-eight invitations were sent, and 39 (81.3%) participants responded. All respondents favoured LT4 tablet therapy for treatment of hypothyroidism, but 20.5% prescribed combination therapy (LT4 and liothyronine), and 13% regularly used desiccated thyroid extract. A significant proportion (51%) might prescribe TH in euthyroid patients; 41% for thyroid auto-antibody positive women seeking pregnancy, 18% for goitre and 5% for unexplained fatigue. Many (38%) consider combination therapy in patients with persistent symptoms. Respondents reported seeing LT4 treated patients with persistent symptomatology more frequently and perceive psychosocial factors and comorbidities to be the most common reasons for such symptoms.

Conclusion
LT4 tablets are the treatment of choice for hypothyroidism in Ireland. Approximately a third of Irish endocrinologists either regularly use, or would consider, liothyronine for hypothyroid patients. A significant proportion would give TH to euthyroid individuals in specific circumstances. The prescription of TH amongst Irish endocrinologists was generally in keeping with recommended practice, and areas where practice deviated from guidance were typically where evidence was conflicting or insufficient.

Published: December 2022

AbstractGlycogen Synthase Kinase-3 (GSK-3) was recently implicated in the dysregulated biology of acute myeloid leukemia (AML). Low concentrations of GSK-3 inhibitors, SB216763 and BIO, suppressed the proliferation of AML cells with FLT3-ITD as early as 24 h after treatment. BIO was used in subsequent assays since it exhibited higher inhibitory effects than SB216763. BIO-induced G1 cell cycle arrest by regulating the expression of cyclin D2 and p21 in MV4-11 cells, and promoted apoptosis by regulating the cleaved-caspase3 signaling pathways. In vivo assays demonstrated that BIO suppressed tumor growth, while metabolomics assay showed that BIO reduced the levels of ATP and pyruvate in MV4-11 cells suggesting that it inhibited glycolysis. BIO markedly suppressed cell growth and induced apoptosis of AML cells with FLT3-ITD by partially inhibiting glycolysis, suggesting that BIO may be a promising therapeutic candidate for AML.

Published: December 2022

AbstractThis study aims to estimate six different sexual debut ages in heterosexual Norwegians in six birth cohorts of the general population in Norway. The results are based on a 2020 national web panel survey of 18–89-year-olds in Norway (n = 4160). There was a general decline in the median debut age from those aged 70+ to those 18–29 (born 1991–2002). Oral sex with a female partner has become increasingly common among men at an earlier age across generations. The same pattern was found in women as well with regard to oral sex with a male partner and receptive anal sex. There was a slight increase in median debut age in 18–29-year-olds for receptive vaginal sex (born 1991–2002). The median debut age for vaginal sex was fairly stable for generations of men and women born after 1950.
Predictors of UK postgraduate researcher attendance behaviours and mental health-related attrition intention
Authors: Berry Clio , Niven Jeremy E. , Hazell Cassie M. 
Published: December 2022

AbstractHigh rates of postgraduate researchers (PGRs) terminate their studies early. This attrition can have detrimental personal consequences, and results in a loss of productivity, and research and innovation for the higher education sector and society as a whole. PGRs are vulnerable to the experience of mental health problems; a factor that appears to be increasing attrition amongst students in the UK. However, investigation of the determinants of problems with PGRs’ attendance and influencing intention to discontinue their studies is rare. Here, we consider the relative predictive validity of a set of putative predictors (mental health symptoms, demographic, occupational, psychological, social, and relational) of attendance behaviours (absenteeism, presenteeism, mental health-related intermission) and early attrition intention amongst UK PGRs. Depression, anxiety, and suicidality predicted attendance behaviours and greater attrition intention. Individual demographic and occupational factors predicted all outcomes. Psychological, social and relational factors had less predictive validity, although individual variables in these conceptual clusters did significantly predict some outcomes. Our results suggest that interventions to reduce high rates of mental health problems are likely to improve attendance behaviours, and reduce the extent to which PGRs intermit or consider ending their PhD studies for mental health-related reasons. Initiatives designed to improve supervisory relationships and reduce loneliness may also reduce absenteeism, intermission and attrition intention.
Biased information processing and anxiety coping: differences in attentional and approach patterns towards positive cues in repressors
Authors: Exner Anna , Machulska Alla , Stalder Tobias , Klucken Tim 
Published: December 2022

AbstractIndividual differences in emotional coping styles are likely to affect information processing on different stages. Repressive coping is assumed to be related to an attentional bias away from threatening information. Possible links to biases in later stages of information processing have not been investigated to date. In the current study, 82 participants completed the visual dot-probe task as a measure of attentional bias and the Approach-Avoidance Task (AAT) as a measure of approach/avoidance bias and classified into coping groups via the Mainz Coping Inventory (MCI). Prevalence of attention bias and approach/avoidance bias were compared between groups. Main results revealed a strong approach tendency toward positive stimuli for repressors and a strong avoidance tendency for sensitizers. No group differences were found for approach bias to negative stimuli or for attention bias. The present findings of strong preferential processing of positive stimuli in repressors may be part of broader information processing alterations, which may also be linked to alterations in emotion processing.

Authors: Basse Tobias , Reddemann Sebastian , Rodriguez Gonzalez Miguel 
Published: December 2022

AbstractThis empirical study examines the dividend policy of insurance companies in Italy after the Global Financial Crisis. There is clear evidence for dividend signaling in this period of time. Moreover, the relationship between stock prices and dividend payments is analyzed in more detail. Additionally, the paper also discusses macroeconomic and regulatory issues that could be of relevance for the dividend policy of the Italian insurance industry. In this context the study exemplarily discusses the possible role of inflation and of regulatory restrictions on dividend payouts in the financial services industry.
The effects of building position on surface and fatigue of DED-arc steel components

Published: December 2022

Abstract
Recently, additive manufacturing (AM) of structural metallic components is analyzed regarding its potential use by industry and research. Next to the development of manufacturing processes, the mechanical properties are under investigation today. One of the quality measures of metallic components is the surface topography. DED-arc processes (direct energy deposition) result in relatively coarse surfaces, characterized by a distinct waviness with wave amplitudes in the mm-range. This is enhanced when applying horizontal building position in comparison to vertical position. Next to increased waviness, the load-bearing net cross sections are reduced as well. The surface topography determines the fatigue life properties of metallic components. While stress raising surface effects are generally well understood and fatigue (Structures 31: 576–589, 2021) of welded metals is established well, the fatigue behaviour of additively manufactured components is less investigated yet. In order to define surface quality levels for DED-arc components, the effects of surface topography on mechanical performance need to be understood. This article presents the manufacturing of high strength steel test coupons by the DED-arc process. The process parameters were varied with regard to the building position and different levels of surface quality were generated. The surfaces of different specimens were characterized and fatigue tests were conducted. The results were used to derive the surface influence on both, the effective load-bearing wall thickness and notch effects induced by the layer-by-layer building approach. A correlation between building position, surface waviness and fatigue strength was proven. In general, higher waviness resulted in reduced effective wall thickness and lowered fatigue strength. A difference in fatigue strength at 2 million load cycles of 20 to 30% was proven when printing in different building positions. The surface effect can be captured in the design concept when applying the effective notch stress approach with an averaging length of of ρ* = 0.4 mm. The fatigue strength is describable by a design S–N curve FAT160 and a k-value of 4.

Published: December 2022

AbstractThe cyber-physical production system (CPPS) was developed for the interconnection between operational technology (OT) and information and communication technology (ICT) among the machines and decentralized production control. However, OT and ICT are now getting more complex in the modern industry. To enhance industrial management and production process, the CPPS based on the 5G architecture under production environments can provide a more comprehensive solution in the context of Industry 4.0. For this purpose, a 5G CPPS model to improve the interoperability of CPPS in ICT and OT is proposed to build a virtualized Industry 4.0 asset management shell system. First, real-time task artifacts and 5G communication modules are bound in a certain form of virtualization. Second, task artifacts are released to the production line in a real-time scheduling. Third, an order is placed on a production line and split into multiple tasks for production process. Single-machine single-workpiece and multi-machine and multi-workpiece processing cases are used for testing in the production line. Experimental results show that the proposed 5G CPPS can efficiently achieve multi-machine work piece processing.

Published: December 2022

AbstractAim:This study aimed to evaluate the retinal nerve fibre layer changes among different group of patients with schizophrenia and compare it with healthy controls by using swept-source optical coherence tomography.Methodology:Patients with first-episode schizophrenia (n = 21) in remission (n = 35) or with treatment-resistant schizophrenia (TRS) (n = 35) and 36 healthy controls were evaluated for retinal thickness.Results:Patients with psychotic illnesses had significantly lower sub-foveal choroidal thickness (effect size 0.84–0.86), when compared to the healthy controls. When patients with first-episode schizophrenia were compared with patients with TRS, TRS patients had significant lower sub-foveal choroidal thickness (left eye) when the various confounders (such as age, gender, duration of treatment, smoking, current medications, body mass index, waist circumference, blood pressure, fasting glucose, HbA1c, presence or absence of metabolic syndrome) were taken into account. When the patients with TRS were compared with healthy controls, initially significant differences were observed for the macular volume (left and right) and the ganglion cell thickness (right eye) but these differences disappeared after controlling for the various covariates.Conclusions:Compared to healthy controls, patients with schizophrenia, psychotic illnesses have thinning of the retina, especially in the sub-foveal choroidal thickness.
Hadrian's Wall and Border Studies: Problems and Prospects
Authors: Gardner Andrew 
Published: December 2022

ABSTRACTHadrian's Wall remains one of the most iconic elements of Roman frontier infrastructure, with considerable symbolic capital in all kinds of contemporary situations and representations. Whether inspiring the fictional ice wall in Game of Thrones or illustrating debates about English–Scottish relationships in Brexit-era Britain, the Wall has a powerful legacy. In more scholarly circles, the Wall sometimes figures in the literature of the emerging field of Border Studies, too, and in this paper I examine some of these representations, as a prelude to discussing what Border Studies offers to Wall studies within Roman archaeology. While the interdisciplinary nature of Border Studies can mean that Hadrian's Wall is misunderstood when taken out of context, this does not mean that the broader insights of Border Studies have no value to Roman archaeologists in better interpreting the Wall and its place in Roman Britain. To the contrary, the combination of innovative theories of frontiers and borderlands with detailed, nuanced understanding of the Wall communities through time has much to offer the archaeology of Britain in the Roman empire. Indeed, this field has the potential to connect frontier studies better with other dimensions of Roman provincial archaeology than has been typical in our discipline over much of the last half-century.
Accommodating China's Floating Population: Local Variations and Determinants of Housing Policies for Rural Migrant Workers
Authors: Peng Chenhong , Wang Julia Shu-Huah 
Published: December 2022

AbstractWhat are the various ways in which local governments in China accommodate migrants through housing policies, and what are the forces that drive these variations? Through systematic coding of policy documents from 97 prefecture-level cities, this study captures the patterns of migrant housing policies using cluster analysis. We found that 18.6 per cent of the cities adopted a residual approach. Most cities adopted a rental-based approach (public and private rental, and collective rental) that could only meet migrants’ short-term housing needs. Only a few cities (12.4 per cent) adopted a citizenship-oriented approach, which best fits the central government's overarching goal of facilitating migrant workers’ long-term settlement in the host cities. Regression analyses examining the determinants of local migrant housing policies showed that the policy variations were not only shaped by economic and political concerns but also the salience of urban issues (problem-solving functions) and previous welfare generosity (path-dependency tendencies).
Short‐Term Forecasting of Wind Gusts at Airports Across CONUS Using Machine Learning
Authors: Coburn Jacob , Arnheim Julian , Pryor Sara C. 
Published: December 2022

AbstractShort‐term forecasting of wind gusts, particularly those of higher intensity, is of great societal importance but is challenging due to the presence of multiple gust generation mechanisms. Wind gust observations from eight high‐passenger‐volume airports across the continental United States (CONUS) are summarized and used to develop predictive models of wind gust occurrence and magnitude. These short‐term (same hour) forecast models are built using multiple logistic and linear regression, as well as artificial neural networks (ANNs) of varying complexity. A suite of 19 upper‐air predictors drawn from the ERA5 reanalysis and an autoregressive (AR) term are used. Stepwise procedures instruct predictor selection, and resampling is used to quantify model stability. All models are developed separately for the warm (April–September) and cold (October–March) seasons. Results show that ANNs of 3–5 hidden layers (HLs) generally exhibit higher hit rates than logistic regression models and also improve skill with respect to wind gust magnitudes. However, deeper networks with more HLs increase false alarm rates in occurrence models and mean absolute error in magnitude models due to model overfitting. For model skill, inclusion of the AR term is critical while the majority of the remaining skill derives from wind speeds and lapse rates. A predictive ceiling is also clearly demonstrated, particularly for the strong and damaging gust magnitudes, which appears to be partially due to ERA5 predictor characteristics and the presence of mixed wind climates.
