In order to investigate the drag reduction mechanisms of vibration digging shovel from the kinematics and mechanical aspects, and to estimate the magnitude of its traction resistance, we performed kinematic analysis when the velocity of the digging shovel was undergoing sinusoidal changes. Based on the analysis of the relationship between vibration direction angle, ascending direction angle and the edge motion curve, we evaluated the efficacy of different mining modes and proposed the ideal working conditions. We found that when the vibration direction angle φ <0 it could produce favorable cutting conditions. When the cutting direction angle θ was slightly less than or equal to the buried angle α and the ascending direction angle λ <π/2, the traction resistance was the least and soil-crushing effect was enhanced. The application of the moving viscous friction resistance model of mining shovel to analyze the force, including the impact of cutting speed on vibration viscous friction, could optimize the ideal working state and deduce the horizontal traction resistance formula of cutting and ascending. This model will be conducive to the structural design of vibration digging shovel and the estimation of its traction resistance.

LABURPENA: Artikulu honetan, Europar Batasuneko botere-artikulazio berriak erkidegotan osatutako Espainian zer eragin daukan aztertuko dugu. Europa mailako politika-ekonomia erlazioak funtsezko bi koordenatu izan behar ditu ezinbestean. Alde batetik, Europako konstituzio-ordena ez dela gizartearen konstituzionalismoaren koordenatuetan ernatutako ordenaren berdina. Bestetik, Europako konstituzio ekonomikoa Europa bat egiteko proiektuak berarekin dakartzan aldaketa berriak gorpuzteko eremua dela. Izan ere, funtsean, Europako konstituzio ekonomikoa plataforma ezin hobea delako boterearen artikulazioa berria nola artikulatu asmatzeko, Europa guztirako. RESUMEN: el objetivo de este artículo es analizar el impacto que tiene la nueva articulación del poder en la Unión Europea en el Estado español de las autonomías. La relación política-economía a nivel europeo debe tener en cuenta dos coordenadas fundamentales. Por una parte, la consideración del orden constitucional europeo como un orden distinto al gestado bajo las coordenadas del constitucionalismo social. Por otra, la caracterización de la constitución económica europea como ámbito de materialización de las nuevas transformaciones que incorpora el proyecto de integración europeo. Fundamentalmente, porque la constitución económica europea representa la plataforma idónea desde la que dilucidar la nueva articulación del poder desde el espacio supranacional europeo. ABSTRACT: The aim of this paper is to analyse the impact of the new articula tion of power in the European Union in the Spanish state of autonomies. The relationship between politics and economy at European level must take into consideration two fundamental coordinates. On the one hand, the Euro pean constitucional system appears as a system opposite to that of social constitutionalism. Moreover, the characterization of the European economic constitution as a field of realization of the new transformations incorporated by the European project. Specially, because this represents the ideal platform in order to analyse the new articulation of power from European supranational space.

Over the past decades there has been a dramatic increase in academic research on motivation to learn a second or foreign language (L2). The present study tried to investigate the relationship between the ideal L2 self as a motivational variable and willingness to communicate in English (L2 WTC) inside the classroom. Participants were 56 university students majoring in English as a foreign language (EFL) at a private university in Ankara, Turkey. Data were collected using the Ideal L2 Self Scale and Willingness to Communicate inside the Classroom Scale. Findings of descriptive statistics indicated that 32.1% of the participants had high L2 WTC inside the classroom, 30.4% had moderate L2 WTC inside the classroom, and 37.5% had low L2 WTC inside the classroom. Findings also revealed a significant relationship between these two constructs noticing the relations at a skills specific level. The implications are discussed to present ideas to language teachers, teacher trainers, and curriculum designers to raise their awareness on the impact of ideal L2 self on willingness to communicate.

Recently, most transportation systems have used an integrated electrical machine in their traction scheme, resulting in a hybrid electrified vehicle. As a result, an energy source is required to provide the necessary electric power to this traction portion. However, this cannot be efficient without a reliable recharging method and a practical solution. This study discusses the wireless recharge solutions and tests the system’s effectiveness under various external and internal conditions. Moreover, the Maxwell tool is used in this research to provide a complete examination of the coils’ position, size, number, and magnetic flux evolution when the coils are translated. In addition, the mutual inductance for each of these positions is computed to determine the ideal conditions for employing the wireless recharge tool for every charging application. A thorough mathematical analysis is also presented, and the findings clearly demonstrate the relationship between the magnet flux and the various external conditions employed in this investigation.

This paper analyses a collection of musical life histories, drawn from 71 British respondents who have maintained a lifelong interest in music as regular concert-goers, amateur performers and/or music educators. These respondents reflect on the influences and opportunities which have contributed to their lifelong engagement in music, and in doing so illustrate the impact of changes in British music education and culture over the last 50 years. Particular analytical focus is placed here on the relative influence of home and school, on the ideal characteristics of each environment, and the relationship between them. The value of a long-term perspective on music education is debated, and conclusions drawn about the challenges to teachers and researchers that are evident from this study.

The object of research is the relationship between the state and the individual under totalitarian and liberal regimes. Investigated problem: in the article the concepts of totalitarian and liberal regime is analyzed, their nature and relation are revealed. The characteristics of each of them are considered. It highlights the impact that they have on the ideal of kalokagathia is highlighted. In a society in which the ideas of kalokagathia can be realized, there must be freedom, which is the most important value of the individual. Both directions of democratic thought ‒ totalitarianism and liberalism welcome the higher value of freedom. A person can’t independently distinguish what is good, harmonious for it, and what is evil, it is not able to make competent decisions, it is always under the influence of the outside world and its conditions. Political regimes can be considered to a large extent, as the basic conditions for human existence. In some cases, these conditions can both stimulate a person and suppress it. This can lead to the fact that government agencies of direct action and coercion can make decisions for it or give rise to the right of permissiveness and thought only of oneself. The main scientific results: historically, the state is called upon to realize the protective function of comprehensive harmonious human development (the ideal of kalokagathia) at the national level, but under the conditions of the presented regimes, this process undergoes various transformations and can’t be fully realized and does not correspond to reality. The harmonious development of man is always full of dissonances and struggles of various forces in the human being.

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.
