Many ecological variables, such as day length, temperature, food availabil- ity, are supposed to effect on activity budgets allocation of temperate primates. To examine the potential influence of these three variables, the activity budgets ofRhinopithecus bieti was studied at Xiaochangdu, Tibet from June 2003 to March 2005. Pearson correlations were utilized to assess potential relationships between activity budget and day length, food availability and temperature, and stepwise multiple regressions to identify the priority of resting and other activities (activities besides feeding, moving and resting). Time spent resting and doing "other activities" is positively related to day length, temperature and food availability. No significant correlations were found between feeding/moving time and any of these variables. This suggests that foraging time (feeding + moving) takes priority over rest and other activities. Day length and foraging time (as independent variables) were related to the time spent in the other two activities besides feeding/moving (as dependent variables). Both time spent resting and in "other activities" were highly significant positive functions of day length, with the latter a highly significant negative function of feeding time and moving time. Resting time may therefore be interpreted as taking priority over "other activities" time. These results provide further evidence of the importance of day length, temperature and food availability to seasonal activity budgets [Current Zoology 56 (6): 650q559, 2010].展开更多

It viewed the seizure of power as the great mission of the proletariat, actively struggled against bourgeois regimes, strongly responded to the call of times for the theoretical self-consciousness and organized struggle of the proletariat, and exerted a profound historical influence on the stirring inauguration and nationally oriented development of the international Communist movement of the 20th century. From the socialist party political perspective, the First Intemational, once the Communist League, had raised the curtain on socialist party politics, changed the political mode of capitalist party politics' exclusive world domination through the interactive development of new organizational forms, theoretical viewpoints and political practice. It thus left an abundant historical legacy in terms of ideological creation and practical innovation for the subsequent Second International, the Communist International and the emergence and development of socialist party politics within nation-states. Although its socialist party political practice had an obvious "regional," "preliminary" and "tentative" nature, the First International had foundation-laying significance and pioneering value for the development of socialist party politics, whether in terms of organizational vehicles, value orientation and activity content, or in terms of ideological guidance, practical patterns and strategic principles.展开更多

Data were measured via a heart rate variability analysis system that utilizes the camera of smartphones. This system was developed by the authors during previous research. The relations between autonomic nervous system and behaviors, total power and sympathetic nervous activity were found to rise after waking, while during leisure time, the total power rises and sympathetic nervous activity is inhibited. Concerning the relationship between autonomic nervous system and day of the week, it was found that total power decreases from the middle through the latter part of the week (namely, Wednesday, Thursday, and Friday), while it rises on Saturday, while the sympathetic nervous activity is suppressed on Saturday. Regarding the relationship between autonomic nervous system and region, it was found that total power is lower in the Kanto region of Japan than in others. This study also shows statistical proof (using a large amount of measurement data) to ideas held by the public for years. Thus, the data can be considered meaningful to the society, and the authors hope that it helps to improve work-life balance.展开更多

They got a strong support from similar organizations of German workers living in Sudety. The coordinating role was played by the German Socio-Democratic party in Slovakia. The major concentration of these unions was in Bratislava and Eastern Slovakia. Concerning their specialized field, they can be divided into tourism-practising, physical and sport ones However, the union activities were strongly influenced by political parties. Activities of every union were regional and therefore a strong mutual isolation existed展开更多
