Agate bandwidths are analyzed and shown to consist of spatial chirps. It is shown that (a) bands are created by following an equal volume mode and (b) the spatial chirps are approximately spherical and concentrated at different “disturbance” locations in the individual agate sectors. Results indicate that the sequence of formation started with banding under a nonlinear process in a gel matrix and were secondarily deformed by external forces.

This article presents the results of a theoretical study of self-realisation, self-actualisation and self-efficacy phenomena. The main aspects of understanding and correlating these phenomena in classical and modern Russian and foreign psychology are described. The highlighted concepts related to the phenomenon of self-realisation, both in the field of psychology and pedagogy. The similarities and differences of the self-realisation, self-actualisation, self-efficacy phenomena, as well as their correlation and comparison are presented. A comparative analysis of the studied concepts is given. According to the results of the theoretical analysis, the processes of self-realisation and self-actualisation are based on the inner motivation of a person to grow, develop personality, realise its potential. Both of these processes, due to their subjectivity, are difficult to observe and measure from the outside. We have highlighted the main differences, consisting in a greater awareness and orderliness of the process of self-realisation, as well as its predominantly "social" orientation, while self-actualisation is often associated with the struggle with external forces, the desire for self-realisation is rather approved and supported by the society. The concepts of self-realisation and self-efficacy are united by their inherent representation in the external plane of the life of the individual, as well as awareness, activity, goal-setting, and an orientation towards achieving success. In contrast to self-efficacy, self-release is a process rather than a sustainable phenomenon, and can be expressed both externally and internally through a connection with the value-semantic, motivational spheres of the individual.

Purpose – The goal of the leadership development process is to enable the individual to learn how to become a self-leader and for any organization to develop leaders. Self-leadership represents an individual's ability to exercise control (self-efficacy) over his or her choice of situations in which to participate in and to provide intrinsic rewards that are usually associated with achieving goals. The paper aims to discuss these issues. Design/methodology/approach – This study presents and describes a conceptual model that will help us to understand the critical dimensions (e.g. self-esteem) associated with self-leadership and the interrelatedness of these dimensions. Findings – The conceptual model that the author describes in this paper provides a comprehensive overview of self-leadership that extends Neck and Manz's (2010) conceptual model. It does so by identifying all the critical super ordinate mediators referred to by Deci et al. (1981) as internal states (referred to in this study as “dimensions”). These “dimensions” are then organized into his or her own singular system which leads to specific types of behavior. Through elucidating the important mediators and learning about and understanding how behavior, an individual's internal processes and external forces influence each other (in what Manz, 1986; Bandura, 1978 refer to as reciprocal determinism), we can begin to understand how to design more effective leadership development programs. Additionally, by studying these mediators any organization can develop clearly defined profiles of potential leaders; in turn, this will help an organization screen candidates more effectively to fill leadership jobs. Originality/value – This concept piece offers a comprehensive model of the self-leadership process that includes all the important issues and the relationship among the important issues.

The article explores how Zygmunt Bauman's work from Modernity and the Holocaust to his liquid turn writings assumes that people live in a deterministic world. Bauman fails to distinguish agency as an analytical category in its own right and as such fails to capture self-determination, agential control and moral responsibility. All of Bauman's work is based upon the assumption that the individual loses their autonomy and the ability to judge the moral content of their actions because of adiaphortic processes external to themselves as individuals giving rise to agentic state in which the individual is unable to exercise their agency. In contrast to the argument in Modernity and the Holocaust this article suggests that the Nazis developed a distinct communitarian ethical code rooted in self-control that encouraged individuals to overcome their personal feeling states, enabling them to engage in acts of cruelty to people defined as outside of the community. In his post-2000 work where the emphasis is on the process of liquefaction there is the same undervaluing of human agency in the face of external forces reflected in Bauman's concepts of ambivalence, fate and swarm.

This study is an attempt to understand the concept of culture as a creative and cultural influence of external factors in fostering creativity. Culture is believed to be one of the aspects that can facilitate the growth of individual creativity. Creative culture as behavior, activity or way of life of a person or group of people embedded within it an element of novelty to life effective, communicative and refer to attitudes toward the social situation and the phenomenon of life. This study attempted to reveal the dominance of internal and external forces that encourage individual creativity. Of the 198 participants were high school students known that the external aspect dominates 63% as the force that drives one's creativity. Socializing creative culture from an early age is expected to facilitate the growth of creativity in the individual.

Abstract Carbon particles in rubber are at first distributed as individual particles by the shearing action of milling, but the individual particles are in a state of Brownian movement due to the kinetic energy of the system. This causes the particles to drift about at a rate determined by the size of the particles, or particle aggregates, and the effective viscosity of the segments of the rubber molecules which is less than one hundredth of that of bulk rubber. The particles thus soon come into contact with each other, and since they are of a disordered crystalline structure and possess relatively high free surface forces, they cohere. The mobility of the aggregates of the particles is much less than that of the individual particles, due to their large size and size relative to that of the rubber molecules, so finally they are relatively immobilized into a scaffoldlike structure of carbon particles. This structure can be broken by external forces, and the broken structural units reform in vulcanized rubber to a structural state at a rate, and to an extent determined by the kinetic energy of the system. The idea of increasing structure formation with rise in temperature is apparently contrary to the kinetic theory, but the persistance of a stable conductivity value in passage from a high to a lower temperature rules out particle motion as the prime cause of conductivity. Furthermore the attainment of a discrete value for the conductivity (Figure 19) at any temperature rather than an alteration of the rate of change towards some maximum value, suggests that temperature activated energy barriers exist—possibly between the carbon and the rubber—which have to be broken before the carbon particles are free to move. Such a system explains the conductive properties of carbon-rubber mixes containing carbon particles of 250 to 300 A.U. diameter, but the properties of systems containing carbons of greatly different particle size may be considerably different. There is some evidence that the cohesion of carbon particles into structural units is sufficiently high to withstand the shearing forces involved during milling and processing treatments of unvulcanized rubber, and so carbon, structure formation from individual particles is of an irreversible nature. As the structural units grow in size under the influence of the kinetic energy of the system they become increasingly less mobile. This gives rise to permanent reduction in conductivity if the structure built up is violently disturbed; for example, if unvulcanized rubber is remilled after appreciable structural formation has taken place.

AbstractThe English language is seen by the Chinese as a tool of significant pragmatic value, both by the individual and the state. Discourse on English language education within China has, both historically and at present, pitted the pragmatic value of English against concerns of cultural and linguistic erosion and imposition. Concerns over the corrupting impact the English language may have on the Chinese language, and further on Chinese culture, uneasily coexist with an acceptance of the English language’s role as the key to modernization and economic development. Voices of past and present, have at their core a desire for the protection of a reified cultural identity or essence. However, cultural and linguistic influence has not merely been imposed upon China from external forces, but has been actively drawn in by domestic forces. Such domestic forces range from foreign language education policies that meet the demands of a globalized market-driven economy, to a market demand for English language media such as TV programs, movies and literature. Ultimately, the presence and significance of these domestic forces undermines a view of the English language as a vehicle of cultural imperialism in China.

1. An attempt has been made to analyse the kinetic effects as observed on the sole of a gastropod in locomotion, and to illustrate these effects by analogy with mechanical models. 2. The internal mechanism involves during locomotion an internal force of longitudinal contraction, and an internal force of extension: the former is considered to be represented by the contracting longitudinal muscles, the latter is probably produced by hydrostatic pressure. The external forces acting on the animal at any one moment represent the balance of the two antagonistic internal forces. 3. During normal ambulation in Pomatias elegans the posterior margin of the foot is exclusively protracted by the longitudinal contraction of the musculature of the foot; the anterior margin is propelled forward exclusively by the force of extension. 4. There is no evidence in favour of an antagonism of longitudinal and transverse fibres in Pomatias elegans; both sets of muscles appear to contract and relax synchronously in one half of the foot and to act antagonistically with both sets of muscles in the other half. 5. The external forces in Pomatias are set up between one area of fixation and an area of dynamic friction. 6. An experimental analysis of the snail showed the existence of an external force of extension (longitudinal thrust) acting between the anterior and the central region of the sole. A similar force of longitudinal contraction (tension) acts between the central and the posterior end. Both forces are of the order of 2.5 g. in Helix pomatia, and about 1 g. in H. aspersa. 7. A static reaction from the ground has been demonstrated to exist under the relaxed parts of the sole. This force reaches a maximum at a point near the central region of the foot. 8. Dynamic friction has been recorded under the forward gliding zones of contraction. 9. Static thrusts are developed between successive areas of fixation in the anterior region, while similar tensions can be observed posteriorly. 10. The foot of the snail as a whole must be considered as a mechanical unit; the individual locomotory waves do not represent mechanically balanced systems.

Ethnomethodology is the study of everyday practices carried out by members of society in everyday life. Actors are seen to do their everyday life through various kinds of ingenious practices. Ethnomethodology develops in various ways. The two main types are institutional studies and conversational analysis. Ethnomethodology has a different perspective from structural and interactionist theories in viewing social reality. As explained above, structural theory sees the most significant picture of human social life in the external forces that compel the individual. Therefore, to understand social behavior, an understanding of structural determination in human life must be developed. Meanwhile, for interactionists, actors (individuals) are viewed as priority objects. So, this theory builds a comprehension by first understanding individual social actions.

Human movement is brought about by the musculoskeletal system under the control of the nervous system. By coordinated activity between the various muscle groups, forces generated by the muscles are transmitted by the bones and joints to enable the individual to maintain an upright or partially upright posture and bring about voluntary controlled movements. Biomechanics of human movement is the study of the relationship between the external forces (due to body weight and physical contact with the external environment) and internal forces (active forces generated by muscles and passive forces exerted on other structures) that act on the body and the eff ect of these forces on the movement of the body. This chapter specifically addresses developmental biomechanics as it relates to the development of coordination in children.

Cleistopycnidial ontogeny and sequences of nuclear internal transcribed spacers (ITS) and large subunits (LSU) were compared for five strains of Endoconidioma populi Tsuneda et al.: three from trembling aspen and two from alder. The cleistopycnidia of two of the aspen strains, including the type strain, were subglobose to flask-shaped (mostly 35–100 µm × 30–60 µm), and consisted solely of meristematic cells with thick cell walls that were heavily impregnated with melanin granules. Peridial cells were not visibly differentiated from locular cells and were also capable of forming endoconidia. Endoconidia were released from one to several sites of the cleistopycnidium by the dissolution of peridial cell wall. The alder strains shared these characteristics, except that their cleistopycnidia released both endoconidia and conidiogenous cells. Unlike those four strains, cleistopycnidia of the third aspen strain were cylindrical, often exceeding 500 µm in length, branched, and possessed a peridium of textura angularis that developed from short, determinate hyphae. Conidiogenous cells contained abundant lipid bodies that were not mobilized until the onset of endoconidiogenesis. The peridium at the basal area was prone to breakage by external forces, indicating that the individual cleistopycnidium, as a whole, functions as a dispersal unit. A small number of ITS nucleotide differences among strains corresponded to their observed morphological differences and host association. Phylogenetic analyses suggested a close relationship of E. populi with Hormonema carpetanum Bills, Peláez & Ruibal, and Coniozyma leucospermi (Crous & Denman) Crous.
