Authors: Kazemi Ashraf , Beigi Marjan , Najafabadi Hajar Enteshary 
Published: December 2022

Abstract
Background
Women’s experiences of birth environment influence their mental health and that of their families. Identifying women’s childbirth experiences in the labor–delivery–recovery–postpartum unit (LDRP) unit, can help design a peaceful environment. Therefore, this study aimed to evaluate women’s childbirth experiences in the LDRP unit.
Methods
This qualitative study was conducted on 20 women with a childbirth experience in LDRP unit. A purposive sampling was performed and continued until data saturation. The data were collected through unstructured interviews and analyzed using inductive content analysis.
Results
Data analysis led to the extraction of three categories: physical security, meaning-oriented environment, and physical comfort. The physical security category was obtained from the sub-categories: privacy, bed ergonomics, and the possibility of medical interventions. The meaning-oriented environment category was extracted from the sub-categories: promising symbols of becoming a mother, peaceful environment, and spiritual environment, and the physical comfort category was extracted from the sub-categories: minimizing noise pollution, ambient lighting, and LDRP internal design.
Conclusions
The results of the study indicate that the experience of childbirth in LDRP unit is influenced by physical and emotional environmental factors. Therefore, in order to design a peaceful environment, it is necessary to take into account these factors.

On a linarization of Koopmans recursion
Authors: Zdun Marek 
Published: December 2022

Abstract
Let X be a metric space and U : X∞ → R be a continuous function satisfying the Koopmans recursion U(x0, x1, x2, . . .) = φ(x0,U(x1, x2, . . .)), where φ : X × I → I is a continuous function and I is an interval. Denote by ⪰ a preference relation defined on the product X∞ represented by a function U : X∞ → R, called a utility function, that means (x0, x1, . . .) ⪰ (y0, y1, . . .) ⇔ U(x0, x1, . . .) ≥ U(y0, y1, . . .). We consider a problem when the preference relation ⪰ can be represented by another utility function V satisfying the affine recursion V (x0, x1, x2, . . .) =α(x0)V (x1, x2, . . .)+β(x0). Under suitable assumptions on relation ⪰ we determine the form of the functions φ defining the utility functions possessing the above property. The problem is reduced to solving a system of simultaneous functional equations. The subject is strictly connected to a problem of preference in economics. In this note we extend the results obtained in Zdun (Aequ. Math. 94 (2020)).

Abstract
The synthesis and design of two-dimensional supramolecular assemblies with specific functionalities is one of the principal goals of the emerging field of molecule-based electronics, which is relevant for many technological applications. Although a large number of molecular assemblies have been already investigated, engineering uniform and highly ordered two-dimensional molecular assemblies is still a challenge. Here we report on a novel approach to prepare highly crystalline molecular assemblies with tunable structural properties. We make use of the high-reactivity of the carboxylic acid functional moiety and of the predictable structural features of non-polar alkane chains to synthesize 2D supramolecular assemblies of 4-(decyloxy)benzoic acid (4DBA;C17H26O3) on a Au(111) surface. By means of scanning tunneling microscopy, density functional theory calculations and photoemission spectroscopy, we demonstrate that these molecules form a self-limited highly ordered and defect-free two-dimensional single-layer film of micrometer-size, which exhibits a nearly-freestanding character. We prove that by changing the length of the alkoxy chain it is possible to modify in a controlled way the molecular density of the “floating” overlayer without affecting the molecular assembly. This system is especially suitable for engineering molecular assemblies because it represents one of the few 2D molecular arrays with specific functionality where the structural properties can be tuned in a controlled way, while preserving the molecular pattern.

Published: December 2022

Abstract
The most effective way to prevent potential suicide attempts is early identification followed by prompt treatment. Nowadays, online communication channels especially social media is becoming a way of expressing suicidal tendencies. However, the availability of properly tagged textual data is a major issue for researchers to perform identification or classification of such tendencies through texts. In light of the abovementioned facts, in the present work, we have proposed an approach to determine early detection with the goal of early diagnosis of suicidal behaviour through text posted on social media via supervised learning using few shot learning process. Therefore, to detect suicidal behaviour, we extract embeddings by finetuning a large pre-trained language model. The contextual embeddings have then been used for binary classification of the text for suicidal behaviour, in which a comparison of various classifiers has been performed. This includes traditional supervised classifiers and neural network models. A comparison of the model’s performance with and without an outlier detection and removal step has also been performed to highlight the importance of the outlier detection step in the pipeline. The feasibility and practicality of the approach have been demonstrated by generating results for user-generated content scraped from Reddit platform posts made on subreddits ‘SuicideWatch’ and ‘depression’. The results generated by the model are also seen to outperform various state-of-the-art models.

Abstract
Respiratory infectious diseases have seriously harmed people's daily lives. The analysis of urban functional spatial structure from the perspective of prevention and control of respiratory infectious diseases has practical significance for optimizing the urban functional spatial structure and slowing down the spread of infectious diseases. In this study, kernel density, random forest, geographic weighted spatial analysis, and other methods were used to investigate the spatial relationship between the urban functional spatial structure constructed from multi-source data and confirmed tuberculosis cases. A summary of the main driving factors and the heterogeneous influence of patient gender was provided. Results showed that: (1) the infection risk of confirmed cases in the urban central area was highest and relatively concentrated; (2) the main functional area characteristics that led to the cluster of patients were commercial services (0.4217, 0.2693, 0.3647), and shopping services were the first driving factor of infection risk; (3) In the stratified analysis, the spatial distribution of male patients was greater than that of female patients. Compared to the overall analysis of patients, the spatial correlation between male patients and park green space was the most significant over three years.There is an increasing spatial correlation between public management and the influence location of each functional area. Because of the similarities in spatial transmission and pathology between tuberculosis and COVID-19, this study provides a scientific basis and methodological reference for the scientific prevention and control and precise policy implementation of COVID-19.

Abstract
Understanding what are the proximate mechanisms shaping species’ space-use dynamics, and at which scale, can provide insights into species socio-ecology. This is crucial information for both applied (e.g., conservation) and theoretical questions (e.g. individuals’ coexistence/segregation). Yet, longitudinal views of the space-use dynamics of animal species are generally lacking. Taking advantage of an unprecedented long-term data set (up to 8 years) on ranging patterns of wild western gorillas (Gorilla gorilla), we investigated the dynamics of home ranges in relation to socio-ecological variables in five habituated groups in Central Africa. First, we looked at the scale at which their ranging movements are stationary. Second, we studied how space use is shaped by (i) foraging and intra-group constraints (e.g., diet, group size, presence of offspring) by focusing on group daily path lengths, and by (ii) inter-group competition (direct or indirect), by quantifying static and dynamic interactions in neighbouring group-dyads. We found that gorilla groups shifted the barycenter of their home range 0.17 per year by a distance larger than the mean home range radius. Movements within the home range were highly dependent on an ecological factor (seasonal diet) and on the group composition, particularly on the presence of dependent infants. Repeatedly visited sites were also used the longest, but their locations differed seasonally, suggesting use of mnesic abilities for foraging. There was little overlap between the home ranges of neighbouring groups that did not tend to move away from each other more than expected at random. Groups also ventured into, and slept in, the central part of the home range of a neighbouring group. Overall, this highlights the absence of territoriality and suggests that spatial segregation should be the simple consequence of avoidance of depleted areas. This study shows how social and ecological constraints may shape space-use patterns at different scales in a non-territorial species. It also raises questions on the cognitive mechanisms underlying high foraging efficiency in environments shared with competitors.
A complete conformational study of N-formyl-D-serine-D-alanine-NH2 dipeptide
Authors: Chahkandi Behzad , Chahkandi Mohammad 
Published: December 2022

Abstract
The conformational analysis of N-formyl-D-serine-D-alanine-NH2 dipeptide was comprehensively studied using the density functional theory methods in the gas and solution phases. The all-expected 35=243 stable conformers were explored, where 91 conformers were located, and the rest of them were migrated to the more stable geometries. Migration pattern suggests the more stable dipeptide model with the serine in βL, γD, γL and the alanine in γL and γD configurations. The investigation of side-chain–backbone interactions revealed that the most stable conformer, γD–γL, is in the β − turn region of the Ramachandran map; therefore, serine-alanine dipeptide model should be adopted with a β − turn conformation. QTAM consideration of the intramolecular hydrogen bonding in β-turns disclosed the highest stable conformer as γD–γL includes the three hydrogen bonds. The computed UV-Vis spectrum alongside of NBO calculation showed and explained the five main electronic transition bands derived of n→ n* of intra-ligand alanine moiety of dipeptide structure.

Published: December 2022

Abstract
Background
The initial responses to the COVID-19 pandemic in Denmark and Sweden differed markedly. Balancing disparate concerns was crucial to generate trust in the COVID-19 restrictions. Political trust is public support for core political institutions. The aim was to investigate the extent to which there was trust in the handling of the pandemic by the Danish and Swedish governments and trust in the handling of the pandemic by the leading public health authorities in each country. A further aim was also to investigate the characteristics of those in Denmark and Sweden who expressed the lowest degree of trust.
Methods
Cross-sectional surveys were conducted in 2021, using web panels that are nationally representative of the socio-demographic characteristics. The population consisted of 2619 individuals from Denmark and 2633 from Sweden, representative of the age, sex and region of residence of the populations aged ≥ 18 years. Trust was captured in two questions: trust in how the government and the public health authority in each country had handled the pandemic. Responses on the two trust items were on a five-point Likert scale. Those who expressed “very small trust” or “moderately small trust” were labelled “low trusters”.
Results
Approximately 61% of the Danish respondents expressed moderately large or very large trust in the government’s handling of the pandemic. The corresponding proportion for Sweden was 42%. The proportion of low trusters was 11% in Denmark and 34% in Sweden. Moderately large or very large trust in the public health authority’s handling was expressed by 83% of the Danish respondents and 74% of the Swedes. The proportion of low trusters was 5% in Denmark and 17% in Sweden. In both countries, trust was lower among men than among women and among those aged < 65 years compared with those > 65 years.
Conclusions
Danes expressed significantly higher trust in their government’s handling of the pandemic than Swedes. In both countries, trust in the public health authority’s handling of the pandemic was higher than that for the government’s handling. Several socio-demographic characteristics were associated with lower trust in handling the pandemic by the government and public health authority.

Abstract
This paper assessed energy conservation and efficiency awareness practices of households in the Cape Coast Metropolis of Ghana. It examined the level and variability in energy conservation practices and the level of energy-savings awareness education among households. The findings reveal that years spent in school by household heads, income levels, expenditure, age of households, and the number of times electricity power triples off daily were among the key factors influencing an individual’s choice of energy-efficient appliances. There was significant variability between existing social strata in terms of income and use of electrical appliances among households. Based on the findings, this study recommends a robust energy literacy program to improve households’ energy efficiency practices awareness, and in order to ensure energy cost savings, environmental protection, and climate change mitigation that will enhance the drive towards achieving sustainable development goals seven (SDG 7).
Low social-support and trouble paying for basic needs during pregnancy are associated with increased risk of autism spectrum disorder in offspring at 3-years: A prospective cohort study

Published: December 2022

Abstract
Purpose
Few studies of risk factors for autism spectrum disorder (ASD) have been prospective in design or investigated the role of psychosocial factors measured during pregnancy. We aimed to investigate associations between prenatal psychosocial factors - including stress, social-support, depression, and trouble paying for basic needs - and risk of ASD in offspring, as part of a multicenter prospective cohort study of more than 2,000 mother-child pairs.
Methods
Nulliparous women aged 18–35 years, living in Pennsylvania, USA, were interviewed during pregnancy and multiple times postpartum over the course of a 3-year period. There were 2,388 participants who completed the Screen for Social Interaction Toddler Version (SSI-T), a measure of risk of ASD, when their child was 36 months old. We investigated the association between a variety of adverse psychosocial factors experienced during pregnancy and risk of ASD in offspring at the age of 3-years, controlling for relevant confounding variables.
Results
There were 102 children (4.3%) who scored as at risk of ASD at 3-years. Based on multivariable logistic regression, prenatal psychosocial factors that were significantly associated with risk of ASD were low social-support and trouble paying for basic needs. Other factors associated with risk of ASD were low maternal education, maternal use of antibiotics and antidepressants during pregnancy, and having a male child. None of the pregnancy or delivery complications were associated with risk of ASD.
Conclusion
These findings suggest that maternal experience of adverse psychosocial factors during pregnancy may be important intrauterine exposures related to the pathogenesis of ASD.
Forecasting Financial Market Structure from Network Features using Machine Learning

Published: December 2022

Abstract

We propose a model that forecasts market correlation structure from link- and node-based financial network features using machine learning. For such, market structure is modeled as a dynamic asset network by quantifying time-dependent co-movement of asset price returns across company constituents of major global market indices. We provide empirical evidence using three different network filtering methods to estimate market structure, namely Dynamic Asset Graph (DAG), Dynamic Minimal Spanning Tree (DMST) and Dynamic Threshold Networks (DTN). Experimental results show that the proposed model can forecast market structure with high predictive performance with up to $40\%$ improvement over a time-invariant correlation-based benchmark. Non pair-wise correlation features showed to be important compared to traditionally used pair-wise correlation measures for all markets studied, particularly in the long-term forecasting of stock market structure. Evidence is provided for stock constituents of the DAX30, EUROSTOXX50, FTSE100, HANGSENG50, NASDAQ100 and NIFTY50 market indices. Findings can be useful to improve portfolio selection and risk management methods, which commonly rely on a backward-looking covariance matrix to estimate portfolio risk.
Algunos alcances sobre la constitucionalización del Derecho
Authors: Espinoza Ariza Jelmut 
Published: December 2022

El presente trabajo desarrolla algunos alcances sobre el denominado Constitucionalismo, el mismo que es entendido como una teoría del Derecho que supera el paradigma del positivismo clásico, en el sentido que no sólo se preocupa por seguir el procedimiento establecido de producción de normas jurídicas (aspecto formal), sino también de su contenido, el mismo que se encuentra regulado por principios y valores vinculantes de carácter moral (aspecto material). El objetivo de la investigación es poner de relieve las principales características que presenta el Constitucionalismo, como 1) el de su rigidez para producir reformas a su texto, lo que permite asegurar la perdurabilidad del mismo, así como la supremacía del texto constitucional sobre otras normas; 2) basarse en la unidad de la razón práctica, al admitir que existe un vínculo entre el Derecho y la moral; y 3) el reconocer la distinción entre reglas y principios, y que sobre estos últimos se realiza un juicio de ponderación ante una eventual colisión de derechos. Asimismo, poner en evidencia la forma cómo se ha desarrollado el denominado control de convencionalidad en el sistema interamericano de derechos humanos.

Introduction. Nowadays the standard of care for locally advanced and metastatic urothelial carcinoma (UC) is a combination of platinum-based drugs. However, such a therapy is characterized with high toxicity and selective efficacy. So, the question of the optimal alternative to the first line of therapy and the choice of drugs for the second line of therapy is currently relevant.Immune checkpoint inhibitors have revolutionized the treatment of UC. Nevertheless, despite the fact that initially the drugs of this series showed a fairly high efficacy as a second-line therapy for metastatic UC, at present there is no unambiguous opinion about the correct tactics of their use. There is also no consensus on the predictive value of PD-L1 biomarkers and their significance in determining treatment tactics.Aim. To evaluate the efficacy and tolerability of first-line atezolizumab therapy in 22 patients with unresectable forms of UC.Materials and methods. The experience of the State Clinical Hospital named after D.D. Pletnev on the example of 22 patients with advanced UC who received first-line therapy with atezolizumab 1200 mg intravenously once every 21 days until progression or intolerable toxicity. Efficacy was assessed according to RECIST 1.1 criteria.Results and discussion. Median follow-up 16.3 months. The objective response rate (ORR) is estimated at 72.7%, 95% CI. A complete response according to RECIST 1.1 criteria was observed in 5 patients (22.7%). Median time to first response was 2.2 months (range 1.5-5.7), late responses (at 5 and 5.7 months) required space in 2 patients. Median progression-free survival was 5.2 months (95% CI) in all patients. Median overall survival (OS) 18.5 months (95% CI). Specific application-related events were required in 10 (45.4%) cases. All the side effects were managed by standard symptomatic therapy. The dosage of atezoli-zumab was reduced in 7 (32%) cases. Immune-mediated adverse events were reported in 5 (23%) patients. No patient received systemic non-corticosteroid immunomodulatory agents for immune-mediated events. 2 (9%) patients received corticosteroids.Conclusions. Atezolizumab has shown high efficacy in the first line of treatment for advanced UC.
