A new generalization of the Pareto distribution and its applications
Authors: Almetwally Ehab M. , Haj Ahmad Hanan A. 
Published: December 2020

Abstract
This paper introduces a new generalization of the Pareto distribution using the Marshall-Olkin generator and the method of alpha power transformation. This new model has several desirable properties appropriate for modelling right skewed data. The Authors demonstrate how the hazard rate function and moments are obtained. Moreover, an estimation for the new model parameters is provided, through the application of the maximum likelihood and maximum product spacings methods, as well as the Bayesian estimation. Approximate confidence intervals are obtained by means of an asymptotic property of the maximum likelihood and maximum product spacings methods, while the Bayes credible intervals are found by using the Monte Carlo Markov Chain method under different loss functions. A simulation analysis is conducted to compare the estimation methods. Finally, the application of the proposed new distribution to three real-data examples is presented and its goodness-of-fit is demonstrated. In addition, comparisons to other models are made in order to prove the efficiency of the distribution in question.
Modelling bid-ask spread conditional distributions using hierarchical correlation reconstruction
Authors: Duda Jarosław , Gurgul Henryk , Syrek Robert 
Published: December 2020

Abstract
While we would like to predict exact values, the information available, being incomplete, is rarely sufficient - usually allowing only conditional probability distributions to be predicted. This article discusses hierarchical correlation reconstruction (HCR) methodology for such a prediction using the example of bid-ask spreads (usually unavailable), but here predicted from more accessible data like closing price, volume, high/low price and returns. Using HCR methodology, as in copula theory, we first normalized marginal distributions so that they were nearly uniform. Then we modelled joint densities as linear combinations of orthonormal polynomials, obtaining their decomposition into mixed moments. Then we modelled each moment of the predicted variable separately as a linear combination of mixed moments of known variables using least squares linear regression. By combining these predicted moments, we obtained the predicted density as a polynomial, for which we can e.g. calculate the expected value, but also the variance to determine the uncertainty of the prediction, or we can use the entire distribution for, e.g. more accurate further calculations or generating random values. 10-fold cross-validation log-likelihood tests were conducted for 22 DAX companies, leading to very accurate predictions, especially when individual models were used for each company, as significant differences were found between their behaviours. An additional advantage of using this methodology is that it is computationally inexpensive; estimating and evaluating a model with hundreds of parameters and thousands of data points by means of this methodology takes only a second on a computer.

Sociological Aspects of Judges in Granting Applications for Marriage Dispensation (Study of Determination Number: 0038/Pdt.P/2014/PA.Pt)
Authors: Adila Arina Hukmu 
Published: December 2020

<p>Many children have a pregnancy out of wedlock. Many factors make the parents marry off their underage children who are pregnant out of wedlock, by applying for matrimonial dispensation to the Religious Courts. Law Number 1 Year 1974 on Marriage has set a minimum age limit for men and women to marry with age and psychological maturity considerations, for the realization of the purpose of the marriage. This study uses a juridical-empirical method, which will see the Religious Courts as the authorized institution, having particular considerations in granting marriage dispensation applications in order to fulfill the rights of the people and to preserve the order of life in the community.</p><p align="center">[]</p><p><em>Banyak terjadi anak-anak mengalami kehamilan di luar nikah akibat dari pergaulan yang terlalu bebas antara laki-laki dan perempuan.

Authors: Statsenko M. E. , Fabritskaya S. V. , Ryndina Y. A. 
Published: December 2020

Objectives: to assess the functional state of the kidneys and cardiovascular risk in relation to the level of leptin and adiponectin in patients with chronic heart failure (CHF) and obesity.Materials and methods: a total of 116 patients with CHF of I-III functional class (FC) 45-65 years old were examined, which were divided into three comparable groups depending on body mass index (BMI).Results: a statistically significant decrease in glomerular filtration rate (GFR), a significant increase in the level of albuminuria (AC) and β2-microglobulins (β2-MG) among patients with chronic heart failure and obesity were revealed. The leptin level significantly increased from the 1st to the 3rd group, the adiponectin concentration decreased from the 1st to the 3rd group. Significant correlations were established between the concentrations of adipokines, HOMA-IR and GFR, AC, β2-MG in the group of individuals with heart failure and obesity.Conclusions: reliable deterioration of renal functional parameters in patients with CHF, statistically significant relationships between GFR, AC, β2-MG and adipokines, HOMA-IR with increasing body weight, as well as an increase in the combined risk of CKD progression and the development of cardiovascular complications with comparable FC were established.

Authors: Kosmachova E. D. , Iakovenko M. S. , Yumukian K. A. 
Published: December 2020

Purpose: to attract the attentio n of therapeutists, gastroenterologists, and infectious disease specialists to the problem of treating the combined course of inflammatory bowel diseases (IBD) and chronic viral hepatitis.Fundamentals: the rate of ulcerative colitis (UC) detection in the population tends to increase. We are accumulating experience in treating patients with IBD and concomitant diseases (oncopathology, tuberculosis, and viral hepatitis). The implementation of standards of treatment for IBD is undoubtedly difficult due to the presence of many contraindications dictated by the presence of a concomitant disease.Conclusion: timely decision on antiviral therapy in patients with a combination of IBD and HCV improves the prognosis of the disease, allows to prolong remission, prevent complications, and has an impact on performance, quality and life expectancy.
Identifying Self-Management Support Needs for Pregnant Women With Opioid Misuse in Online Health Communities: Mixed Methods Analysis of Web Posts
Authors: Liang Ou Stella , Chen Yunan , Bennett David S , Yang Christopher C 
Published: December 2020

Background
The current opioid crisis in the United States impacts broad population groups, including pregnant women. Opioid use during pregnancy can affect the health and wellness of both mothers and their infants. Understanding women’s efforts to self-manage opioid use or misuse in pregnancy is needed to identify intervention points for improving maternal outcomes.

Objective
This study aims to identify the characteristics of women in an online health community (OHC) with opioid use or misuse during pregnancy and the self-management support needs of these mothers.

Methods
A total of 200 web posts by pregnant women with opioid use participating in an OHC were double coded. Concepts and their thematic connections were identified through an inductive process until theoretical saturation was reached. Statistical tests were performed to identify patterns.

Results
The majority of pregnant women (150/200, 75.0%) in the OHC exhibited signs of misuse, and 62.5% (125/200) of the participants were either contemplating or pursuing dosage reduction. Self-managed withdrawal was more common (P<.001) than professional treatment among the population. A total of 5 themes of self-management support needs were identified as women sought information about the potential adverse effects of gestational opioid use, protocols for self-managed withdrawal, pain management safety during pregnancy, hospital policies and legal procedures related to child protection, and strategies for navigating offline support systems. In addition, 58.5% (117/200) of the pregnant women expressed negative emotions, of whom only 10.2% (12/117) sought to address their emotional needs with the help of the OHC.

Conclusions
OHCs provide vital self-management support for pregnant women with opioid use or misuse. Women pursuing self-managed dosage reduction are prone to misinformation and repeated relapses, which can result in extreme measures to avoid testing positive for drug use at labor. The study findings provide evidence for public policy considerations, including universal screening of substance use for pregnant women, emphasis on treatment rather than legal punishment, and further expansion of the Drug Addiction Treatment Act waiver training program. The improvement of web-based platforms that can organize geo-relevant information, dispense clinically validated withdrawal schedules, and offer structured peer support is envisioned for harm reduction among pregnant women who opt for self-management of opioid misuse.
Effects of the Active Choices Program on Self-Managed Physical Activity and Social Connectedness in Australian Defence Force Veterans: Protocol for a Cluster-Randomized Trial
Authors: Gilson Nicholas D , Papinczak Zoe E , Mielke Gregore Iven , Haslam Catherine , Fooken Jonas , McKenna Jim , Brown Wendy J 
Published: December 2020

Background
A stepped-down program is one in which clients transition from the care of a health professional to self-managed care. Very little is known about the effectiveness of stepped-down physical activity (PA) programs for military service veterans.

Objective
This study will test Active Choices, a stepped-down behavioral support program designed to help Australian Defence Force veterans and their dependents who are clients of the Department of Veterans’ Affairs, transition from treatment by an exercise physiologist or physiotherapist to self-managed PA.

Methods
The study is a parallel-group, randomized trial, with city-based exercise physiology or physiotherapy practices that recruit eligible Department of Veterans’ Affairs clients assigned to Active Choices or a comparison program. The study aims to recruit 52 participants (26 in each group). The Active Choices program will consist of 2 face-to-face (Weeks 1, 12) and 2 telephone (Weeks 4 and 8) consultations. During these sessions, the participant and Active Choices consultant will utilize an evidence-based resource booklet to review the key benefits of an active lifestyle, build an action plan for PA preferences, set and review goals, self-monitor progress relative to set goals, and discuss strategies to overcome PA barriers. Linking participants to local PA communities to overcome social isolation will be a program priority. The comparison program will consist of 2 consultations (Weeks 1 and 12) and use fewer behavioral support strategies (education, self-monitoring, and action planning only) than Active Choices. Outcome measures will be administered at baseline, end-intervention (12 weeks), and follow-up (24 weeks) to assess changes in moderate intensity self-managed PA, psychological well-being, and social connectedness. We will also measure health service utilization and costs as well as PA choices across the intervention period. End-intervention interviews will capture participant experiences.

Results
Due to the impacts of the COVID-19 pandemic on human research activities in Australia, participant recruitment will commence when it is safe and feasible to do so.

Conclusions
Findings will provide valuable pilot data to support up-scaling of the program and larger effectiveness trials with regional and rural as well as city-based Australian Defence Force veterans and their dependents.

Remote Measurement in Rheumatoid Arthritis: Qualitative Analysis of Patient Perspectives
Authors: White Katie M , Ivan Alina , Williams Ruth , Galloway James B , Norton Sam , Matcham Faith 
Published: December 2020

Background
Rheumatoid arthritis (RA) is characterized by recurrent fluctuations in symptoms such as joint pain, swelling, and stiffness. Remote measurement technologies (RMTs) offer the opportunity to track symptoms continuously and in real time; therefore, they may provide a more accurate picture of RA disease activity as a complement to prescheduled general practitioner appointments. Previous research has shown patient interest in remote symptom tracking in RA and has provided evidence for its clinical validity. However, there is a lack of co-design in the current development of systems, and the features of RMTs that best promote optimal engagement remain unclear.

Objective
This study represents the first in a series of work that aims to develop a multiparametric RMT system for symptom tracking in RA. The objective of this study is to determine the important outcomes for disease management in patients with RA and how these can be best captured via remote measurement.

Methods
A total of 9 patients (aged 23-77 years; mean 55.78, SD 17.54) with RA were recruited from King’s College Hospital to participate in two semistructured focus groups. Both focus group discussions were conducted by a facilitator and a lived-experience researcher. The sessions were recorded, transcribed, independently coded, and analyzed for themes.

Results
Thematic analysis identified a total of four overarching themes: important symptoms and outcomes in RA, management of RA symptoms, views on the current health care system, and views on the use of RMTs in RA. Mobility and pain were key symptoms to consider for symptom tracking as well as symptom triggers. There is a general consensus that the ability to track fluctuations and transmit such data to clinicians would aid in individual symptom management and the effectiveness of clinical care. Suggestions for visually capturing symptom fluctuations in an app were proposed.

Conclusions
The findings support previous work on the acceptability of RMT with RA disease management and address key outcomes for integration into a remote monitoring system for RA self-management and clinical care. Clear recommendations for RMT design are proposed. Future work will aim to take these recommendations into a user testing phase.
Cross-border cooperation at the external border of the European Union in the context of political, economic and social conditions: the case of the Polish-Russian neighbourhood
Authors: Batyk Iwona M. , Rzeczkowski Daniel 
Published: December 2020

Research background: Integration and globalization processes encourage activities for the development of border regions. For the north-eastern regions of Poland and the Kaliningrad region, cross-border neighbourhood enables regions to cooperate and provides an opportunity for economic and social recovery.
Purpose of the article: The present article aims to analyse areas of cross-border activity taking place on the Polish-Russian borderland, based on the opinions of the inhabitants of the Kaliningrad region. Taking into account the rapidly changing political and economic conditions, as well as social relations, the following areas of Polish-Russian cross-border cooperation have been examined: economic activity, tourism, social activity, scientific cooperation, neighbourly relations.
Methods: The study presents the results of the author?s own research carried out using standardized interviews with 1,022 inhabitants of the Kaliningrad region. As the research instrument, a self-designed interview questionnaire. The adopted time frame encompassed four stages of the functioning of Polish-Russian cross-border cooperation, each of them different due to political, eco-nomic and social conditions. The sample was selected using the quota method. The correspondence analysis was used for statistical tools.
Findings & Value added: The suspension of local border traffic has significantly limited the development of cross-border cooperation. The Polish-Russian relations, encumbered with high risk and uncertainty, have led to a considerable decrease in cooperation between border areas. The level of risk results not only from mutual relations between Poland and Russia, but is also a consequence of political and economic relations between the European Union and the Russian Federation. In the long term perspective, local border traffic may be open and similar conditions for the functioning of cross-border cooperation may occur. Therefore, knowledge about the activity of cross-border residents of Polish-Russian border regions will be useful in counteracting the undesirable effects that may occur.
On the Influence of the Soil and Groundwater to the Subsidence of Houses in Van Quan, Hanoi
Authors: Vinh Dinh Xuan 
Published: December 2020

The area of Van Quan, Hanoi before 2004 was the rice field. Nearby, Ha Dinh water plant has well-drilled underground water for residential activities. Van Quan's new urban area after being formed has detected many subsidences. The objective of this study is to assess the main causes of the subsidence of the houses, based on groundwater and soil. This paper applied the regression method to study the effect of soil and groundwater on the residential constructions in Van Quan urban area, Hanoi. Subsidence monitoring was carried out for 4 consecutive years, from 2005 to 2009, including over 500 subsidence monitoring points with high-precision Ni007 and INVAR gauges. A groundwater observation well is 30 meters deep at the site of the settlement. The results show a small effect of groundwater on subsidence. The characteristics of the young sediment area and the soil consolidation process are the main causes leading to serious subsidence in residential constructions in Van Quan urban area. This paper provides a different perspective on the impact of groundwater on the subsidence of residential structures within approximately 100 ha.
Biological and Ecological Characteristics of the Ladybird Beetle (Lemnia biplagiata Swartz, 1808) (Coccinellidae: Coleoptera)
Authors: Minh Hong Bui , Chien Tran Dinh 
Published: December 2020

This paper studies the ladybird beetle in the laboratory at two average temperature levels: 22.2 ± 0.02 and 30.7 ± 0.03oC with average humidities of 69.5 ± 0.05 and 86.8 ± 0.06%, respectively, using Rhopalosiphum maidis as prey to observe its biological characteristics. The study results show that the ladybird beetle completes its life cycle in a time range from 19.75 ± 5.75 days at 30.7 ± 0.03oC and 86.8 ± 0,06% RH to 25.75 ± 6.50 days at 22.2 ± 0.02˚C and 69.5 ± 0.05% RH. The survival rate of ladybird larvae and the percentage of larvae aged 4 into pupae at 22.2 ± 0.02˚C and 69.5 ± 0.05% RH were higher than those at 30.7 ± 0.03oC and 86.8±0.06% RH by 32.4% and 8.24%, respectively. Using Rhopalosiphum maidis as food, the ladybird beetle larvae’s food consumption increases from age 1 to age 4 and the adults consume more food than the fourth-stage larvae by 11.60 R.maidis/day at 22.2 ± 0.02˚C and 69.5 ± 0.05% RH. At 30.7 ± 0.03oC and 86.8 ± 0.06% RH, the ladybird beetle larvae’s R. maidis food consumption at all phases was about 2.5 times higher than at 22.2 ± 0.02˚C and 69.5 ± 0.05% RH.
Percepción y realidad de la criminalidad en el Tolima durante la República Liberal
Authors: Parada Garcia Gilberto Enrique 
Published: December 2020

Este artículo examina algunos delitos violentos ocurridos en el departamento colombiano del Tolima entre 1930 y 1946 para replantear la percepción que la dirigencia social tolimense tenía de la criminalidad. Se afirma que algunos delitos que han sido asociados a la violencia política en el Tolima después de 1946 se registraron también durante la República Liberal. A partir del análisis de estadísticas y causas criminales, se reconfigura la idea de la criminalidad y se esbozan las principales características del sistema judicial y de la cultura jurídica de los gobiernos liberales, los cuales implementaron nuevas técnicas para contener una presunta escalada delictiva.
