ABSTRACTBackground: Several international studies have substantiated the role of loneliness as a risk factor for mortality. Although both theoretical and empirical research has supported the classification of loneliness as either situational or chronic, research to date has not evaluated whether this classification has a differential impact upon mortality.Methods: To establish the definition of situational vs. chronic loneliness, we used three waves of the Health and Retirement Study (HRS), a nationally representative sample of Americans over the age of 50 years. Baseline data for the present study were collected in the years 1996, 1998, and 2000. The present study concerns the 7,638 individuals who completed all three waves; their loneliness was classified as either not lonely, situational loneliness or chronic loneliness. Mortality data were available through to the year 2004.Results: Those identified as “situationally lonely” (HR = 1.56; 95% CI: 1.52–1.62) as well as those identified as “chronically lonely” (HR = 1.83; 95% CI: 1.71–1.87) had a greater risk for all cause mortality net of the effect of possible demographic and health confounders. Nonetheless, relative to those classified as “situationally lonely,” individuals classified as “chronically lonely” had a slightly greater mortality risk.Conclusions: The current study emphasizes the important role loneliness plays in older adults’ health. The study further supports current division into situational vs. chronic loneliness, yet suggests that both types serve as substantial mortality risks.

Ownership Control

Owned business management inevitably implies the availability of tools for its implementation. The set of tools for such management is effective, when it can be integrated into the overall system of business processes. The problem lies in the selection of those managerial business processes, where the participation of the owner is necessary. Justification of the definition of such business processes is possible on the basis of systematization and identification of the risks, that must be assumed by the business owner. In theory and practice of management, the focus is on the management of the organization, which is implemented by hired specialists-managers. The role of business owners is rarely seen as an independent activity. Meanwhile, the goals and the role of business owners are far from adequate to the goals and roles of managers. This circumstance makes the problem of ownership business management urgent. Currently, the terms “owner contro”l and “ownership management” are used in literary sources. These terms do not coincide in their meaning. Ownership management includes ownership control and occurs when the owner solves the problems of strategic development. If strategic development goals are not set for any reason, the owner remains to develop a system of ownership control over the current state of the business. Ownership business management should be built on the development and control of the organization's business processes. The owner can not physically control all business processes, and this is not necessary. There is a need to highlight those business processes, that he must control necessarily. In our opinion, the solution of this problem can be built on the basis of an appropriate classification of entrepreneurial risks.

Rheumatoid arthritis (RA) is among the most common forms of chronic inflammatory arthritis. It affects approximately 1% of adults and is two to three times more prevalent in women than in men. There are no specific laboratory tests for RA; diagnosis depends on a constellation of signs and symptoms that can be supported by serology and radiographs. The disease evolves over many years as a consequence of repeated environmental stress causing inflammation and immune activation followed by a breakdown of tolerance in individuals with a specific genetic background. This review describes the definition of RA; its etiology, including genetics, infections, the role of smoking and citrullination of proteins, and epigenetic mechanisms; and its pathogenesis, including synovial histopathology, bone and cartilage damage, adaptive and innate immunity, and the role of cytokines and intracellular signaling. Tables include the 1987 American Rheumatism Association criteria for the classification of RA and the 2010 American College of Rheumatology/European League Against Rheumatism classification for RA. Figures show citrullinated proteins in airway cells, a section of a proliferative synovium from a patient with a classic RA, and scalloped regions of erosion at the junction between a proliferative inflamed rheumatoid synovium and the bone. This review contains 3 highly rendered figures, 2 tables, and 71 references.

The introduction of the modern concept of chemical element has often been credited to Lavoisier. I will argue that despite the significant impact of the definition of elements as non-decompound bodies in Lavoisier’s “Elements of Chemistry,” this claim is misleading for at least three reasons. First, elements were already defined as residues of analysis prior to Lavoisier. Second, Lavoisier did not totally give up the traditional view of elements as constituents of all bodies. Third, the modern definition of chemical element implies a clear distinction between simple bodies and elements that was later introduced by Dmitri Mendeleev. I will outline the role of this conceptual distinction in Mendeleev’s process of classification of elements and symmetrically emphasize how the periodic system contributed to stabilize his notion of element as an individual defined by its position in the system. Thus the concept of element appears as both a precondition and a product of the construction of the periodic system.

We develop an approach to risk classification based on quantile contours and allometric modelling of multivariate anthropometric measurements. We propose the definition of allometric direction tangent to the directional quantile envelope, which divides ratios of measurements into half-spaces. This in turn provides an operational definition of directional quantile that can be used as cutoff for risk assessment. We show the application of the proposed approach using a large dataset from the Vermont Oxford Network containing observations of birthweight (BW) and head circumference (HC) for more than 150,000 preterm infants. Our analysis suggests that disproportionately growth-restricted infants with a larger HC-to-BW ratio are at increased mortality risk as compared to proportionately growth-restricted infants. The role of maternal hypertension is also investigated.

ABSTRACTBackground:Falls are highly frequent in older adults and are associated with increased morbidity and mortality. The present study was designed to assess the role of satisfaction with one's aging process as a predictor of the risk for falling over a four-year period and to identify potential mediators of this relationship.Methods:The Health and Retirement Study (HRS) is a US nationally representative sample of individuals over the age of 50 years and their spouse of any age. The present study was based on the 2008–2012 waves of the HRS. Analyses were restricted to 4,121 respondents over the age of 50 years, who had fall data in 2008 and 2012 and were eligible to complete the satisfaction with aging measure as part of the 2008 psychosocial questionnaire.Results:Overall, 38.1% of the sample reported having fallen at least once between 2006 and 2008 and 40.7% reported having fallen at least once between 2010 and 2012. Higher levels of satisfaction with aging in 2008 were found to be protective against falls assessed in 2012 (OR[95%CI] = 0.88[0.79–0.98]) even after adjustment for age, gender, education, ethnicity, medical status, functional status, cognitive functioning, walking speed, balance, vision, depressive symptoms, physical activities, and past falls. Bootstrap procedures have shown that the effect of satisfaction with aging on falls is partially accounted for through its effect on functional decline.Conclusions:The findings point to the important role of satisfaction with aging as a potential protective mechanism against falls. The results call for the development of psychosocial interventions to reduce falls in older adults.

The Relationship

The article reviews the definitions of the tutoring concept in preschoolers relationships. Can we qualify the relationships of preschool children in learning situations as tutoring? Or maybe a different name would be more suitable for them? Preschoolers are used to learning in a different way than adults and older children. They prefer learning mimicking or playing. They obtain knowldge occasionally an unintentionally. In turn, definitions of tutoring quite precisely contain formulated fortifications that a little child is not able to meet yet. Immaturity of the nervous system limit the level and length of attention span of little child and relatively small, compared to school children and adults number of social experiences can seriously hamper the classification of situations in which children learn from each other as tutoring. While the generally understood master-student relationship, associated with tutoring, is quite often noticeable during childhood collaboration and play in which one child can do more than the other, the more detailed assumptions of tutoring are not as accessible to the observer. For example, it is difficult to talk about the regularity or planned nature of children's relationships. The definition of tutoring also sets specific expectations regarding the teacher's skills, among which are: high interpersonal competences, commitment to the relationship with the mentee, professionalism and responsibility. From a preschool child who would play the role of a teacher, it is difficult to demand fluent speech, not to mention professionalism and regularity. A preschool child, who just start to learn numbers, is often unable to orient himself in time, which makes it difficult or even impossible to plan and systematize his activities. Little child needs adult help in this area.

AbstractEducational attainment among women is a well-recognized predictor for maternal mortality. Data from nationally representative surveys and the United Nations are used in the analysis for estimating maternal mortality due to improved education status up to 2030. Analysis of data from 2001 and 2010 Bangladesh Maternal Mortality Survey shows that MMR varies considerably by education level. The study shows that during 2011–2030, 15% maternal deaths will be averted due to fertility change (i.e. fewer births) and 24% of the maternal deaths can be averted only by improving the female education levels. However, in order to achieve the Ending Preventable Maternal Mortality (EPMM) target of 59 maternal deaths per 100,000 live births by 2030 for Bangladesh, a further 64% reduction will be required. Factors outside the health sector, like female education, will continue to have an impact maternal mortality in Bangladesh. However, reaching the EPMM target for Bangladesh by 2030 will also require significant investments in maternal health programs, in particular those to increase access to and quality of services.

The analysis of scientific and practical approaches concerning the identification and classification of stakeholders, the definition of centers of influence on projects were carried out. It has been shown that there is insufficient attention paid to the aspects of proactive interaction with the stakeholders in the project management, the specificity of the projects for the ensuring of municipal energy efficiency is not taken into account. This article proposes to introduce the concept of the proactivity basis, identify the role of stakeholders of the municipal energy efficiency projects and the strength of their influence on the adoption of management decisions. The model of stakeholders of such projects is suggested taking into account the proactive influence on them. The model identifies stakeholders, their roles in municipal energy efficiency projects, and proposes appropriate proactive basis. The principles of proactive communication of the project of ensuring the municipal energy efficiency projects with stakeholders are formulated: the principle of common values, the principle of priority, the principle of continuous monitoring, the principle of feedback effectiveness, and the principle of strategic partnership. The method of proactive communication of the project management system is also developed, which will allow for proactive management of projects to ensure municipal energy efficiency.
