This essay critically analyses the legacy of Eisenstadt's The Political Systems of Empires for the comparative political history of pre-industrial empires. It argues that Eisenstadt has given us a rich toolkit to conceptualize the formation, maintenance, and dissolution of empires by theorizing the structural relationships between social groups in large-scale polities and among such polities, and by analysing global patterns of development in the distribution of the sources of social power. The Political Systems of Empires provides an inventory of key questions and dynamics that a comparative history of power relationships in empires cannot ignore. This essay, furthermore, discusses three methodological problems in Eisenstadt's work which have had a significant impact on comparative empire studies between the 1980s and the 2000s. The essay argues that certain shared features of comparative studies of pre-industrial empires help perpetuate Eurocentric analyses: the foregrounding of select empires and periods as ideal types (typicality), the focus on macro-historical structures and dynamics without the integration of social relationships and actions in historical conjunctures (the lack of scalability), and the search for convergence and divergence. These features need to be overcome to make Eisenstadt's legacy viable for comparative political history.

The purpose of this study is to examine the mediation effects of relationships of parent-child and between-peers based on the effects of economic difficulty on quality of life of elementary school students. Data was obtained from students (N= 493) at seven elementary schools in Choongbuk Province and analyzed with SPSS 12.0 and Structural Equation Modeling with AMOS 5.0. The major findings are as follows: economic difficulty gives a direct effect on elementary students' quality of life and is mediated with parent-child and between-peers relationships. Also, economic difficulty influences children's quality of life when a parent-child relationship is combined with a between-peers relationship. On the basis of these results, this study suggests that welfare centers and elementary schools have to teach students to have desirable sense of value. Also, schools need to provide education programs for parents to improve parent-child relationship and various activities for students to develop between-peers relationship.

The purpose of this study was to assess the causal relationships among hedonic belief, ambivalence, subjective norm, attitude and meat consumption behavior. A total of 318 questionnaires were completed. Structural equation model was used to measure the causal effects of constructs. Results of the study demonstrated that fit of the restricted baseline model is significantly worse than that of the unrestricted proposed model, in which more parameters are estimated. The effects of hedonic belief, ambivalence and subjective norm on attitude were statistically significant. The effects of hedonic belief, subjective norm and attitude on meat consumption were statistically significant. The effect of attitude on intention was statistically significant. Moreover, attitude played a mediating role in the relationships between hedonic belief and meat consumption, between ambivalence and meat consumption, and between subjective norm and intention. This study suggested that the consumer decision-making process for eating meat products is best modeled as a complex system that incorporates both direct and indirect effects on meat consumption. This study believed the evidence presented supports this position. Moreover, this study appeared to be a worthy area of pursuit.

Purpose - This study aims to propose and validate a research model that describes the relationships between customer socialization, customer participation, and customer loyalty in the online service industry. Although customer loyalty is frequently discussed topic in marketing and strategy research, this study takes a novel approach in adopting customer socialization and participation as the antecedents to customer loyalty. Research design, data, and methodology - Based on adopting and modifying measurement items of the constructs from previous studies, this study develops survey regarding the constructs within the proposed research model. Among current registered members of Facebook and DaumKakao, 522 college students and other regular users are selected as the samples for conducting the survey. The collected data is analyzed by structural equation modeling method using SPSS and AMOS. Results Proposed hypotheses of the positive relationships - between customer socialization and customer participation, and between customer participation and customer loyalty are all supported. Conclusions - The results of this study suggest customer participation as an important precursor to customer loyalty in the online service industry. Also, customer socialization is validated as a new strategy to increase customer participation. These results validate the practical importance of communicating mission, purpose, value, and other customer socialization activities that firms undertake.

This study investigated the longitudinal effects of family risk factors, parent-child relationships, and language abilities of children in low-income families in terms of both school adjustment and academic performance. The subjects were 176 children aged 5 to 7 and their mothers. They participated in follow up studies over the next 3 years. The children were tested using the Wechsler Intelligence Scales and language tests; and classroom teachers rated their levels of both school adjustment and academic performance. Mothers reported parent-child relationships, maternal depression, and family economic resources. Data were analyzed using Pearson's correlation, and structural equation modeling (SEM). Our results indicated that there were direct effects of language abilities, and indirect effects of parent-child relationships and maternal depression upon children's school adjustment and academic performance. It was also revealed that language abilities had a mediating effect between parent-child relationship and school adjustment/ academic performance.

Tube hydroforming (THF) under pulsating hydraulic pressures is a novel technique that applies pulsating hydraulic pressures that are periodically increased to deform tubular materials. The deformation behaviours of tubes in pulsating THF may differ compared to those in conventional non-pulsating THF due to the pulsating hydraulic pressures. The equivalent stress-strain relationship of metal materials is an ideal way to describe the deformation behaviours of the materials in plastic deformation. In this paper, the equivalent stress-strain relationships of SS304 tubes in pulsating hydroforming are determined based on experiments and simulation of free hydraulic bulging (FHB), and compared with those of SS304 tubes in non-pulsating THF and uniaxial tensile tests (UTT). The effect of the pulsation parameters, including amplitude and frequency, on the equivalent stress-strain relationships is investigated to reveal the plastic deformation behaviours of tubes in pulsating hydroforming. The results show that the deformation behaviours of tubes in pulsating hydroforming can be well described by the equivalent stress-stain relationship obtained by the proposed method. The amplitude and frequency of pulsating hydraulic pressure have distinct effects on the equivalent stress-strain relationships-the equivalent stress becomes augmented and the formability is enhanced with the increase of the pulsation amplitude and frequency.

This paper presents a method of elastic-plastic analysis for planar steel frames that provides the accuracy of distributed plasticity methods with the computational efficiency that is greater than that of distributed plasticity methods but less than that of plastic-hinge based methods. This method accounts for the effect of spread of plasticity accurately without discretization through the cross-section of a beam-column element, which is achieved by the following procedures. First, nonlinear equations describing the relationships between generalized stresses and strains of the cross-section are derived analytically. Next, nonlinear force-deformation relationships for the beam-column element are obtained through lengthwise integration of the generalized strains. Elastic-plastic flexibility coefficients are then calculated by differentiating the above element force-deformation relationships. Finally, an elastic-plastic stiffness matrix is obtained by making use of the flexibility-stiffness transformation. Adding the conventional geometric stiffness matrix to the elastic-plastic stiffness matrix results in the tangent stiffness matrix, which can readily be used to evaluate the load carrying capacity of steel frames following standard nonlinear analysis procedures. The accuracy of the proposed method is verified by several examples that are sensitive to the effect of spread of plasticity.
