Authors: Alexeenko V V , Seredina N S , Kosaynova V N 
Published: December 2019

Abstract
The human potential is of great importance in modern economy during the period of technological structure change and the transition to the knowledge economy, the imperative of which is the cognitive technology. Human abilities aimed at making managerial decisions strategically important for the progressive development of economic entities are expressed in the process of transforming potential into “new resources”. In this regard, the direction and power of the transformation processes form the basis of the economy. The basic factor in the production of the transformation is human (intellectual) potential. The economic effect obtained as a result of transformation processes is directly dependent on the knowledge of the person, taking the decision. In order to improve the effectiveness of the resources use a methodology for assessing the transformational costs of enhancing the intellectual potential of business entities was developed. The analysis of the products cost structure produced by business entities will make it possible to identify the priority areas for the revitalization of resources necessary for the finished goods production and the conditions for transforming the potential into “new resources”.

Development of a methodology for assessing the financial security of construction enterprises
Authors: Kosaynova V N , Seredina N S , Alexeenko V V 
Published: December 2019

Abstract
One of the key challenges in the housing market is to ensure the developer’s reliability. The transition to the project financing mechanism requires the financial sustainability observation within the limits of the established standards by the specialized developers. In current economic conditions a more comprehensive analysis including not only financial sustainability indicators is needed for the disclosure of the financial situation of a building industry company. The authors selected the indicators groups and identified the specific indicators for the construction industry. These indicators were considered in comparing their actual values with standards. They reflect the financial security. The highest degree of safety is achieved under the condition that the whole complex of indicators is within the permissible limits of its threshold values, and the threshold values of one indicator are achieved with no connection with the others. In the process of implementing the assessment methodology the cumulative indicators were calculated for each group of indicators. On the basis of the above-mentioned, an integral index was obtained for each of the enterprises included in the sample. The authors adapted the financial security assessment model based on the data presented on the portal of the Unified Developers Register taking into account a specific territory (Bryansk Region). The formulated and tested model made it possible to assess the financial security of the largest enterprises in the construction industry, draw appropriate conclusions and propose management solutions within the framework of these or those indicators.

Authors: Menzelintseva Nadezhda , Karapuzova Natalia , Marinina Olga , Yermilova Natalia 
Published: December 2019

Abstract
To improve the reliability of respiratory protection available for workers handling dry mixtures, when dust and noxious gases penetrate the work area, it is necessary to both upgrade the design of the respirators currently in use, and develop new porous layer materials to enhance the protection level along with user convenience. An ion-exchange filtering material has been developed, which offers both protective and hygienic properties. A mathematical model has been created to simulate the half-mask casing of a Snezhok GP-V type respirator. The finite element method was used for stress analysis of the casing.

Individual-Level and Couple-Level Discordant Chronic Conditions: Longitudinal Links to Functional Disability
Authors: Polenick Courtney A , Birditt Kira S , Turkelson Angela , Kales Helen C 
Published: December 2019

Abstract

Background
Multiple chronic conditions may erode physical functioning, particularly in the context of complex self-management demands and depressive symptoms. Yet, little is known about how discordant conditions (i.e., those with management requirements that are not directly related and increase care complexity) among couples are linked to functional disability.

Purpose
We evaluated own and partner individual-level discordant conditions (i.e., discordant conditions within individuals) and couple-level discordant conditions (i.e., discordant conditions between spouses), and their links to levels of and change in functional disability.

Methods
The U.S. sample included 3,991 couples drawn from nine waves (1998–2014) of the Health and Retirement Study. Dyadic growth curve models determined how individual-level and couple-level discordant conditions were linked to functional disability over time, and whether depressive symptoms moderated these links. Models controlled for age, minority status, education, each partner’s baseline depressive symptoms, and each partner’s number of chronic conditions across waves.

Results
Wives and husbands had higher initial disability when they had their own discordant conditions and when there were couple-level discordant conditions. Husbands also reported higher initial disability when wives had discordant conditions. Wives had a slower rate of increase in disability when there were couple-level discordant conditions. Depressive symptoms moderated links between disability and discordant conditions at the individual and couple levels.

Conclusions
Discordant chronic conditions within couples have enduring links to disability that partly vary by gender and depressive symptoms. These findings generate valuable information for interventions to maintain the well-being of couples managing complex health challenges.
Why female birds of prey are larger than males
Authors: Schoenjahn Jonny , Pavey Chris R , Walter Gimme H 
Published: December 2019

AbstractThe causes of the reversed sexual size dimorphism (RSD; females larger than males) in birds of prey are subject to a centuries-old, passionate debate. A crucial difficulty is to distinguish whether the postulated benefits derive from the proposed causal process(es) or are incidental. After reviewing the existing literature, we present a methodology that overcomes this difficulty and renders unnecessary any speculative a priori distinctions between evolved function and incidental effects. We can thus justify the following novel version of the well-known nest defence hypothesis as the most likely to explain the phenomenon in all birds of prey that show RSD: if the female predominates in actively defending the eggs and young against predators, then she is the heavier sex, and her relatively greater body mass is adaptive. That is, heavier females are favoured (independently of males) by natural selection. The attractiveness of this hypothesis is that it has the potential to explain the phenomenon in all raptors exhibiting RSD, can deal with the exceptional cases in this group, explains the direction of the dimorphism, focuses on a key factor in the reproductive success of most raptors, is parsimonious, i.e. does not require supporting hypotheses, and is supported by a substantial body of evidence.

AbstractDetecting and understanding disturbance is a challenge in ecology that has grown more critical with global environmental change and the emergence of research on social–ecological systems. We identify three areas of research need: developing a flexible framework that incorporates feedback loops between social and ecological systems, anticipating whether a disturbance will change vulnerability to other environmental drivers, and incorporating changes in system sensitivity to disturbance in the face of global changes in environmental drivers. In the present article, we review how discoveries from the US Long Term Ecological Research (LTER) Network have influenced theoretical paradigms in disturbance ecology, and we refine a framework for describing social–ecological disturbance that addresses these three challenges. By operationalizing this framework for seven LTER sites spanning distinct biomes, we show how disturbance can maintain or alter ecosystem state, drive spatial patterns at landscape scales, influence social–ecological interactions, and cause divergent outcomes depending on other environmental changes.
Lack of Increased Risk of Lymphoma by Thiopurines or Biologics in Japanese Patients with Inflammatory Bowel Disease: A Large-Scale Administrative Database Analysis
Authors: Kobayashi Taku , Uda Akihito , Udagawa Eri , Hibi Toshifumi 
Published: December 2019

Abstract

Background and Aims
Patients with inflammatory bowel diseases may have higher incidences of non-melanoma skin cancers and non-Hodgkin lymphoma, potentially linked to underlying disease and treatments. This analysis assessed incidence rates of these malignancies in Japanese patients with ulcerative colitis or Crohn’s disease, and their association with thiopurine and/or anti-tumor necrosis factor-α treatment, using data from a nationwide administrative database in Japan.

Methods
Patients diagnosed with inflammatory bowel disease without malignancy were identified from the Medical Data Vision database. Incident cases of non-melanoma skin cancers and non-Hodgkin lymphoma diagnosed after prescription of thiopurine and/or anti-tumor necrosis factor-α were identified between April 2008 and January 2018. Age- and sex-adjusted incidence rate ratios were calculated relative to the total treated patient population.

Results
A total of 75 673 eligible patients were identified at the index date. Thiopurine prescription with or without anti-tumor necrosis factor-α agents increased incidence rate ratios for non-melanoma skin cancers relative to the overall population (3.39 and 4.03, respectively). There were no notable differences in non-Hodgkin lymphoma incidence relative to the total population in any treatment subgroup, regardless of prescription of thiopurine and/or anti-tumor necrosis factor-α (all incidence rate ratios, ~1).

Conclusions
There is no evidence for an increased incidence of non-Hodgkin lymphoma attributable to thiopurine or anti-tumor necrosis factor-α treatment in Japanese patients with inflammatory bowel disease. The impact of racial differences on non-Hodgkin lymphoma incidences should be considered. Thiopurine therapy may be a risk factor for non-melanoma skin cancers in Japanese patients.
Midstory Removal Facilitates Growth but Reduces Competitiveness of Oak Reproduction Prior to and after Shelterwood Establishment Cutting
Authors: Hackworth Zachary J , Lhotka John M , Stringer Jeffrey W 
Published: December 2019

Abstract
This study examined the influence of midstory removal applied 9 years prior to a shelterwood establishment cut on survival, growth, and competitive status of black oak (Quercus velutina Lam.), white oak (Quercus alba L.), and an oak competitor, red maple (Acer rubrum L.), immediately before and at 6 years following shelterwood cutting on intermediate productivity sites in the Central Hardwood Forest Region. We also examined height and density distributions of the regenerating cohort to quantify seedling establishment and to elucidate relative oak competitiveness at each time period. Although oak seedlings were taller 9 years after midstory removal than in undisturbed controls, the midstory removal treatment reduced the frequency of free-to-grow oaks (relative to understory competitors) and increased the size of red maple and relative density of large competitors. Height growth of all three species following establishment cutting was increased by prior midstory removal and dependent on seedling competitive position immediately before shelterwood establishment. Additionally, we observed increased seedling densities 6 years following shelterwood establishment cutting and greater white oak seedling establishment when midstory removal preceded the shelterwood treatment.
Comparative in vitro Study of the biological activity and chemical composition extracts of Helicteres isora L. obtained by water and subcritical water extraction
Authors: Didar Zohreh 
Published: December 2019

Abstract

Objectives
Subcritical water extraction technique is considered as an environmentally extraction technique. The aim of this study was to compare the different characteristics of water extract and subcritical water extract of Helicteres isora L.

Materials and Methods
Water extraction was performed under the following conditions: 25°C, 24 h, and solid-to-water ratio 1:30. Subcritical water extract was carried out under specific conditions (pressure = 10 bar, temperature = 160°C, solid-to-water ratio = 1: 30, time = 30 min). Chemical composition analysis was performed using GC–Mass chromatography. Anti-biofilm activity in the terms of anti-attach and removal of biofilm were assessed using the ELISA reader method and reading absorbance at 570 nm. Anti-microbial activity against Bacillus cereus, Staphylococcus aureus, Staphylococcus saprophyticus, and Bacillus subtilis was investigated by measurement of inhibitory zone diameter. Anti-enzymatic and antioxidant properties were also assessed.

Results
The results of GC–Mass analysis showed some components extracted in subcritical method which were absent in water extract such as octadecanoic acid, hexadecanoic acid, and berberin. Antioxidant activity of the two tested extracts revealed that subcritical water extract had more antioxidant capacity than water extract (P ≤ 0.05). The two tested extracts exhibited anti-enzymatic activity against polyphenol oxidase enzyme with better performance of subcritical water extract. Anti-biofilm activity of the two extracts implies that, in the case of preventing biofilm formation, both extracts had similar efficiency but in the removal of biofilm, subcritical water extract showed better performance. Both extracts had anti-microbial activity against B. cereus, S. aureus, S. saprophyticus, and B. subtilis with better performance of subcritical water extract. Anti-enzymatic assay also showed similar results.

Conclusions
Subcritical water extract of H. isora showed more antioxidant activity as well as anti-biofilm, anti-bacterial, and anti-enzymatic activity rather than ordinary water extract.
A Closer Look at Loneliness: Why Do First-Generation Migrants Feel More Lonely Than Their Native Dutch Counterparts?
Authors: ten Kate Rowan L F , Bilecen Başak , Steverink Nardi 
Published: December 2019

Abstract

Background and Objectives
Along with the current aging demographics in the Netherlands, the number of older first-generation migrants is also increasing. Despite studies suggesting a higher quantity of social contacts of migrants, loneliness is more common among migrants as compared to native Dutch. We theorize that migrants experience more emotional and social loneliness due to a lower satisfaction with social relationships and lower participation in social activities, respectively, compared to their native counterparts.

Research Design and Methods
We use data from Statistics Netherlands (N = 7,920) with first-generation migrants aged 40 years and older and their Dutch counterparts. Contact frequency, household composition, satisfaction with social relationships, relationship quality with the partner, and social activities, are used as main predictors and separate regression models for social and emotional loneliness are analyzed.

Results
Compared to the native Dutch, first-generation migrants are both socially and emotionally more lonely. Migrants have a similar contact frequency as the native Dutch, but are less satisfied with their social relationships, which contributes to their higher emotional, social, and overall loneliness. Migrants engage less in social activities but this does not put them at additional risk of loneliness.

Discussion and Implications
Migrants experience more social and emotional loneliness and are less satisfied with their social relationships compared to their native counterparts. Interventions should focus on reducing both social and emotional loneliness among older migrants. Specific attention should be paid to fostering satisfying social interactions. Additionally, encouraging migrants to broaden their social network may reduce social loneliness.
