Постановка задачи. Необходимо осуществить оценку влияния региональной компоненты на величины магнитуд землетрясений. Результаты. Представлены результаты исследований соотношения между параметрами сейсмогенных разрывов (протяженность, площадь) и магнитудой поверхностных волн M. Предложены эмпирические зависимости, позволяющие оценить магнитуду поверхностных сейсмических волн на основе параметров очаговых зон инструментальных записей землетрясений, зарегистрированных в различных регионах мира. Определено, что на величину M влияют тип сейсмогенные подвижки, а также региональные тектонические особенности территорий. При этом для одних районов региональная составляющая имеет существенное значение, для других решающими факторами являются размеры разрыва и тип подвижки. Выводы. Сравнение результатов расчетов с использованием длины разрыва и площади показали, что зависимости, определенные с применением протяженности разрыва, с большей достоверностью оценивают возможную магнитуду землетрясения. Statement of the problem. The influence of the regional component on earthquake magnitudes must be assessed. Results. The results of studies of the relationship between the parameters of seismogenic discontinuities (length, area) and the magnitude of surface waves M are presented. Empirical dependences are proposed that allow one to estimate the magnitude of surface seismic waves based on the parameters of focal zones of instrumental records of earthquakes recorded in various regions of the world. It is established that M is influenced by the type of seismogenic movement, as well as regional tectonic features of territories, while for some areas the regional component is of significant importance, for others the size of the gap and the type of movement are critical. Conclusions. The comparison of the results of calculations using the gap length and area showed that the dependences determined using the gap length estimate the possible magnitude of the earthquake more accurately.

AbstractUnderstanding the relationship cause/effect between tectonic earthquakes and volcanic eruptions is a striking topic in Earth Sciences. Volcanoes erupt with variable reaction times as a consequence of the impact of seismic waves (i.e. dynamic stress) and changes in the stress field (i.e. static stress). In 2012, three large (Mw ≥ 7.3) subduction earthquakes struck Central America within a period of 10 weeks; subsequently, some volcanoes in the region erupted a few days after, while others took months or even years to erupt. Here, we show that these three earthquakes contributed to the increase in the number of volcanic eruptions during the 7 years that followed these seismic events. We found that only those volcanoes that were already in a critical state of unrest eventually erupted, which indicates that the earthquakes only prompted the eruptions. Therefore, we recommend the permanent monitoring of active volcanoes to reveal which are more susceptible to culminate into eruption in the aftermath of the next large-magnitude earthquake hits a region.

The understanding the processes of decentralization of the economy in a federal state as one of the possible sources of economic development. This understanding requires the revision of the implications that the formation and implementation of a policy of relations between the federal center and the regions entails. The goal of our present research is to develop an approach that will help assess the impact of the nature of relations between the federal center and the regions on economic growth. The theoretical and methodological basis of this study is formed by a set of scientific concepts in the field of economic federalism and spatial analysis. Basing on the index method (by determining the values of decentralization of regional incomes and expenditures) and the implementation of positioning, an assessment was made of the relationship between decentralization and economic growth by such a resulting parameter of the development of the territory as the “growth rate of the gross regional product” and the parameter characterizing the development of federalism relations in the country as “the level of economic decentralization”. According of the calculations we prove there is a positive effect of decentralization processes on regional economic growth in the analyzed time interval. There is a greater impact on the processes of decentralization of the indicator of income decentralization compared to the decentralization of expenses. The results of our research can be used in the work of federal authorities in the formation of the regional component of federalism policy. It seems the proposed approach can basis of research related to the determination of the main directions of relations between regions and municipalities.

This article has two purposes: (a) to examine the relationship between intercultural power relations and the widespread practice of accent discrimination and (b) to underscore the ramifications of accent discrimination both for the individual and for global society as a whole. First, authors review social theory regarding language and group identity construction, and then go on to integrate more current studies linking accent bias to sociocultural variables. Authors discuss three examples of intercultural accent discrimination in order to illustrate how this link manifests itself in the broader context of international relations (i.e., how accent discrimination is generated in situations of unequal power) and, using a review of current research, assess the consequences of accent discrimination for the individual. Finally, the article highlights the impact that linguistic discrimination is having on linguistic diversity globally, partially using data from the United Nations Educational, Scientific and Cultural Organization (UNESCO) and partially by offering a potential context for interpreting the emergence of practices that seek to reduce or modify speaker accents.

Abstract Administrators and supervisors face daily challenges over issues such as program funding, service fees, correct coding procedures, and the ever-changing healthcare regulations. Receiving equitable reimbursement for speech-language pathology and audiology services necessitates an understanding of federal coding and reimbursement systems. This tutorial provides information pertaining to two major healthcare coding systems and explains the relationship of these systems to clinical documentation, the Medicare Physician Fee Schedule and equitable reimbursement. An explanation of coding edits and coding modifiers is provided for use in those occasional atypical situations when the standard use of procedural coding may not be appropriate. Also included in this tutorial is a brief discussion of the impact that the Medicare Improvements for Patients and Providers Act of 2008 (HR 6331 Medicare Improvements for Patients and Providers Act [MIPPA], 2008) has had on the valuation of speech-language pathology procedure codes.

Humans are social animals; consequently, a lack of social ties affects individuals’ health negatively. However, the desire to belong differs between individuals, raising the question of whether individual differences in the need to belong moderate the impact of perceived social isolation on health. In the present study, 77 first-year university students rated their loneliness and health every 6 weeks for 18 weeks. Individual differences in the need to belong were found to moderate the relationship between loneliness and current health state. Specifically, lonely students with a high need to belong reported more days of illness than those with a low need to belong. In contrast, the strength of the need to belong had no effect on students who did not feel lonely. Thus, people who have a strong need to belong appear to suffer from loneliness and become ill more often, whereas people with a weak need to belong appear to stand loneliness better and are comparatively healthy. The study implies that social isolation does not impact all individuals identically; instead, the fit between the social situation and an individual’s need appears to be crucial for an individual’s functioning.

Abstract. Background: Self-esteem is a major contributor to risk for repeated suicide attempts. Prior research has shown that awareness of stigma is associated with reduced self-esteem among people with mental illness. No prior studies have examined the association between self-esteem and stereotype awareness among individuals with past suicide attempts. Aims: To understand the relationship between stereotype awareness and self-esteem among young adults who have and have not attempted suicide. Method: Computerized surveys were administered to college students (N = 637). Linear regression analyses were used to test associations between self-esteem and stereotype awareness, attempt history, and their interaction. Results: There was a significant stereotype awareness by attempt interaction (β = –.74, p = .006) in the regression analysis. The interaction was explained by a stronger negative association between stereotype awareness and self-esteem among individuals with past suicide attempts (β = –.50, p = .013) compared with those without attempts (β = –.09, p = .037). Conclusion: Stigma is associated with lower self-esteem within this high-functioning sample of young adults with histories of suicide attempts. Alleviating the impact of stigma at the individual (clinical) or community (public health) levels may improve self-esteem among this high-risk population, which could potentially influence subsequent suicide risk.

Background: We study the impact of suicide-exclusion periods, common in life insurance policies in Australia, on suicide and accidental death rates for life-insured individuals. If a life-insured individual dies by suicide during the period of suicide exclusion, commonly 13 months, the sum insured is not paid. Aims: We examine whether a suicide-exclusion period affects the timing of suicides. We also analyze whether accidental deaths are more prevalent during the suicide-exclusion period as life-insured individuals disguise their death by suicide. We assess the relationship between the insured sum and suicidal death rates. Methods: Crude and age-standardized rates of suicide, accidental death, and overall death, split by duration since the insured first bought their insurance policy, were computed. Results: There were significantly fewer suicides and no significant spike in the number of accidental deaths in the exclusion period for Australian life insurance data. More suicides, however, were detected for the first 2 years after the exclusion period. Higher insured sums are associated with higher rates of suicide. Conclusions: Adverse selection in Australian life insurance is exacerbated by including a suicide-exclusion period. Extension of the suicide-exclusion period to 3 years may prevent some “insurance-induced” suicides – a rationale for this conclusion is given.
