This article examines the parallels between George H. Mead's theory of time and Boris A. Uspensky's semiotics of history, looking for implications relevant to the symbolic interactionist theory of historical processes. It suggests that Mead's theory of time and theory of communication hold important implications for semiotic analysis of the historical dimension of sociocultural phenomena. A further aim is to link the symbolic interactionist tradition of the Chicago school with the Tartu school and its semiotics of history. This would fuel the further development of both theoretical orientations.  相似文献

The objective of this study was to evaluate the shape of anterior–posterior curvatures of the spine and to determine the values of body symmetry deviations in the frontal plane, in elderly males. The study group consisted of 34 males aged between 61 and 83 years, attending two hour-long training sessions a week. The comparative group consisted of 30 students. The photogrammetric method based on the Moire phenomenon was used to evaluate the body posture. The obtained data confirm characteristic tendencies of physiological spinal curvatures to change with the aging process. A decrease of the lumbar–sacral spinal-segment inclination and an increase of the upper thoracic spinal-segment inclination were observed in the elderly males. Whereas, the value of thoracic kyphosis lower-segment inclination was similar to the value obtained in young adult males. The stated differences indicate a flattening of lumbar lordosis and a deepening of the upper arch of thoracic kyphosis, which results in a characteristic body posture in the standing position with the head protruding and the upper trunk segment inclined. The above-mentioned observations indicate a dominance of the angular thoracic kyphosis value over the remaining spinal curvatures. These differences occur to a greater degree in elderly males.  相似文献

Analyses of data from 600 households in the province of Lubin, Poland, five years after the economic transformation indicated the transfers of goods and services between households to be quite prevalent, with households with high levels of resources giving goods and services and those with low levels of resources receiving goods and services. The receipt of such transfers does not improve the living conditions of the receiving households relative to those who do not receive help; in fact, those receiving help report lower levels of satisfaction than those not receiving assistance.  相似文献

This paper examines the incentives offered by frictionless markets to innovate asset‐backed securities by owners who maximize the assets' values. Assuming identical preferences across investors with heterogeneous risk‐sharing needs, we characterize economies in which competition provides insufficient incentives to innovate so that, in equilibrium, financial markets are incomplete in all (pure strategy) equilibria, even when innovation is essentially costless. Thus, value maximization does not generally result in complete markets.  相似文献

The text refers to the space around the Nathan Rapoport’s Monument to the Fighters and Martyrs of the Ghetto and the Museum of the History of Polish Jews POLIN in Warsaw (Poland). The site of death – at the heart of the former Warsaw Ghetto – has now become a site overloaded with other symbolic messages. Two main symbolic centers (the 1948 Monument and the 2013 Museum) are today encircled by ten other, additional memorials. The message emerging from the content as well as the proportion of commemorations is that Polish solidarity with the Jews was a fact and it stood the test of terror and death brought by the Germans. Although it does not undermine the veracity of the few and isolated exceptions, such a version of events is drastically different from the actual facts. Both symbolic centers are perceived as emblems of Jewish minority narrative. Additional artefacts are a message formulated by the Polish majority. They constitute a kind of symbolic encirclement, block. Emphasizing the dominant majority’s version of the events in this place is in fact a symbolic pre-emptive action. It is meant to silence the unwanted narrative or suppress even the mere possibility that it might emerge. What turns out to be at stake in the dominant Polish narrative about the Holocaust and Polish-Jewish relations is the image of Poland and the Poles. This shows not only the topographic and symbolic situation but also the socio-cultural context of the functioning of the new Museum.  相似文献

ABSTRACT

This paper analyzes migration of Polish healthcare and eldercare workers since Poland's accession to the European Union. The research indicates that while many Polish doctors, nurses, and caregivers ‘left’ Poland, they did not necessarily ‘stay’ abroad. Contemporary Polish migration has become ‘liquid’ and has often taken on a form of ‘pendulum’ or ‘circular’ migration and, in some cases, transnational commuting, especially in the early years following Poland's accession to the EU. These patterns are particularly evident among healthcare and eldercare workers whose flexible working schedules or life stages allow for retaining employment positions and households in Poland while taking short-term or prolonged leave of absence to work abroad. The research also suggests that different migration patterns are related to the characteristics of the place of migrant origin and the geographic distance or proximity of the destination countries. Residents of border towns can easily commute to cities on the other side of the frontier, while those who want to work in geographically more distant countries and cities must, by necessity, consider longer-term or permanent arrangements. The analysis of the variegated mobility of elder care workers is situated in the context of policy discussions related to care drain and care supply as well as quality of migrant care.  相似文献
