Translational and rotational molecular motion in supercooled liquids studied by NMR and forced Rayleigh scattering

1994

It has been shown that translational diffusion coefficients, Dt, in the supercooled van der Waals liquids, orthoterphenyl, phenolphthaleindimethylether, and salol, have a weaker temperature dependence than the shear viscosity, η, at T ≲ 1.2Tg and can be described by Dt ∼ η−χ with χ < 1 whereas Dr ∼ η−1 applies for the mean rotational diffusion coefficients, Dr, down to the glass transition temperature, Tg. This apparent decoupling of translational and rotational motion has been discussed in relation with possible anomalous short time diffusion, spatial heterogeneity, and cooperative molecular motions close to Tg.

Thiolate Adsorption on Au(hkl) and Equilibrium Shape of Large Thiolate-covered Gold Nanoparticles

2013

The adsorption of thiolates on Au surfaces employing density-functional-theory calculations has been studied. The dissociative chemisorption of dimethyl disulfide (CH3S−SCH3) on 14 different Au(hkl) is used as a model system. We discuss trends on adsorption energies, bond lengths, and bond angles as the surface structure changes, considering every possible Au(hkl) with h, k, l ≤ 3 plus the kinked Au(421). Methanethiolate (CH3S-) prefers adsorption on bridge sites on all surfaces considered; hollow and on top sites are highly unfavourable. The interface tensions for Au(hkl)-thiolate interfaces is determined at low coverage. Using the interface tensions in a Wulff construction method, we cons…

Child-centered and teacher-directed practices in relation to calculation and word problem solving skills

2019

Abstract This study examined transactional associations between classroom-level math skills and teaching practices. Participants were 523 children from 31 classrooms. Math skills were assessed three times. Teaching practices were observed in Grades 1 and 3. Child-centered practices promoted subsequent calculation skills whereas teacher-directed practices were associated with a lower level of calculation skills. Higher problem-solving skills at Grade 2 predicted more child-centered practices and less teacher-directed practices in third grade. Moreover, calculation skills mediated the effect of child-centered practices on problem-solving skills. The results suggest that teaching practices and…

Guanxi and social capital: Networking among women managers in China and Finland

2014

Considering that women are still under-represented in management, researchers have claimed that networking is an important career management tool for women. This study aims to empirically explore how women managers benefit from social networks in the information technology (IT) field in China and Finland. Guanxi, an Eastern term for social networking, has seldom been studied in terms of gender and career, especially within cross-cultural research. Social capital is a Western term for social networks. Using questionnaires, in-depth interviews and interpretive analysis, we compare the composition and structure of social networks used by women managers within the information technology sector …

China's economic, environmental and social development in crossfire : province-specific analysis of China's ecological modernization and sustainabili…

2014

Häyhä, Laura. China’s Economic, Environmental and Social Development in Crossfire – Province-specific Analysis of China’s Ecological Modernization and Sustainability. Master thesis. Autumn 2014. Supervisor: Pertti Jokivuori. Sociology. University of Jyväskylä. Pages 89 + 1 appendix. This study concentrated to examine ecological modernization process and sustainability of Chinese provinces. The examination focused on the differences between the westernmost and the easternmost China. Data of Chinese Statistical Yearbook was used during the years 2001–2010. Analyses were implemented with SPSS 20. and Excel 2010. Among general statistical analysis, Principal Component Analysis and a relatively …

A multi-criteria evaluation system for arable land resource assessment

2020

This study proposed a multi-criteria evaluation system for arable land resources by combining the soil integrated fertility index (IFI) with a soil cleanliness index (based on heavy metals and metalloid content). A total of 16 typical arable land units in Chongming District, China, were evaluated using the proposed evaluation system based on 104 collected soil samples in 16 towns. The comprehensive soil evaluation scores of arable lands in 16 towns were in the range of 90.7 to 99.2 with a mean of 96.2, indicating that the arable land in all 16 towns was at the level of excellent (≥ 90.0). Lower cleanliness indices had a significant impact on the final evaluation score. In comparison with si…

An Exploration of Organizational Assimilation Among State-Owned, Private-Owned, and Foreign-Invested Enterprises in China

2017

This study explores organizational assimilation in Chinese organizations. To reflect the Chinese context more accurately, the present study compared employees working in three different kinds of organizations: state-owned enterprises (SOEs), private-owned enterprises (POEs), and foreign-invested enterprises (FIEs). Data collected from 220 full-time employees were analyzed using multiple regression analysis. Regression analyses demonstrated that employees’ level of organizational assimilation was significantly influenced by organizational type: Employees in SOEs reported the highest level and employees in FIEs reported the lowest level of organizational assimilation. peerReviewed

Study of the flying geese theory from a political point of view : a Japanese propaganda argument in the post world war II era

2009

The Flying Geese Theory (gankoo keitai hattenron 雁行形態発展論), dating from 1932, is one of the rare cases of a scientific theory that was used as a part of Japanese wartime propaganda, and which also survived and succeeded in the postwar era. It was used to legitimize the 'New Order in East Asia (TōA shinchitsujo 東亜新秩序) in 1938, and the new formulation of the 'Greater East Asia Co-Prosperity Sphere‘ (Dai TōA kyōeiken大東亜共栄圏) in 1940. Later in the 1980s the Flying Geese Theory/Pattern became the most successful candidate for explaining the expansion of ‗Asian economical miracles‘ in the postwar era. This study focuses on this famous piece of economical and political rhetoric. The intention is to …
