Traditional studies of the modernization-instability thesis have neglected the simultaneous influence of time and place on the relationship between modernization (social mobilization and political participation) and political instability, and the possible causal linkage between the two concepts. Empirical support for modernization-instability hypothesis will be obtained if and only if there is a strong positive correlation between modernization and political instability and the former causes the latter unidirectionally. Only then can one assert that modernization is exogenous, and that a policy geared toward restricting modernization is a proper anti-instability policy. This work attempts to address the question of correlation and causality through a pooled time-series cross-sectional data design and the use of Granger-causality tests. Particular attention is paid to the error structure of the models. Using pooled regression, a model of political instability is estimated for a total of 35 countries for the period 1960-1982. Granger tests are performed on twelve separate countries randomly selected from the 35. The results indicate that there is the expected positive relationship between modernization and political instability. Further, political institutionalization and economic well-being have strong negative influence on political instability. With regard to causality, the results vary by country. Some countries experience no causality between modernization and political instability, while some witness bidirectional causality. Further, some nations experience unidirectional causality running from modernization to political instability, while some depict a reverse causation. The main results suggest that modernization and political instability are positively related, and that political instability can have causal influence on modernization, just as modernization can exert causal influence on political instability.

No / Trade credit terms offer firms contractual solutions to informational asymmetries between buyers and sellers. The credit period permits buyers to reduce uncertainty concerning product quality prior to payment, while the seller can reduce uncertainty concerning buyer payment intentions by prescribing payment before/on delivery or through two¿part payment terms and other mechanisms. Variation in trade credit terms also offers firms price discriminating opportunities. This study, drawing on the responses of 700 large firms in the US, UK and Australia, explores trade credit terms through the twin objectives of reducing information asymmetries and discriminatory pricing. Support is found for both theories.

The quality of educational attainment measures lies at the heart of many cross-national micro-sociological research projects and international education statistics. This study aims at validating cross-nationally comparable measures of educational attainment, among which are the International Standard Classification of Education 1997 (ISCED 97), the CASMIN education scheme and years of education. Following a conceptual discussion of what educational attainment means, the most common ways of measuring educational attainment cross-nationally as well as previous evaluations thereof are reviewed. Then, the implementation of ISCED 97 in cross-national surveys is examined by looking at both the resulting educational attainment distributions in three European surveys as well as the data generation and harmonisation processes. Finally, a number of cross-national measures of educational attainment are compared with country-specific measures with respect to their information content by firstly examining the dispersion of educational attainment, and secondly the predictive power when explaining two core social stratification outcomes, occupational status and social class attainment, by educational attainment. The main results of the study are that the measurement of educational attainment in cross-national surveys is affected by a number of avoidable weaknesses which adversely affect the validity of claims based on analyses of these data: 1. Countries and surveys are inconsistent in the way they measure educational attainment and apply ISCED 97 to national data; and 2. actual years of education and the one-digit version of ISCED 97 distort measures of association to differing degrees in different countries. Both make cross-national comparisons using these measures highly problematic. Therefore, some amendments to the implementation of ISCED 97 in cross-national surveys and coding for statistical analyses are proposed. As part of the latter, an alternative simplification of ISCED 97, optimised for European survey research, is developed and validated. Moreover, suggestions for data collection procedures are made to improve the measurement of educational attainment nationally and cross-nationally.

Using data for 93 countries from 1972 through 2001 in cross-national analysis, this study compares the relative economic strength of a country's middle-class with its civil liberties performance and its history of domestic and external conflict. For purposes of this analysis, the relative strength of a country's middle-class is determined by multiplying the square root of a country's gross domestic product per capita by the percentage of income distributed to the middle 60 % of the population (middle class income share). Comparisons between this measure of per capita income distributed (PCID) and several other indicators show the strength of the relationship between PCID and civil liberties performance and domestic and external conflict. In the same manner, comparisons are made for the middle class income share (MCIS) alone. The countries are also divided by level of PCID into 3 world classes of 31 countries each for additional comparisons. In tests using bivariate correlations, the relationships between PCID and MCIS are statistically significant with better civil liberties performance and fewer internal conflicts. With multivariate regression the relationship between PCID and civil liberties performance is statistically significant but not for PCID and internal conflict. As expected, in both correlations and regression between PCID and external conflict, variables related to power dominate. However, when the countries are divided into world classes by level of PCID, the eleven countries with the highest level of PCID have had no internal or external conflict since 1972. Moreover, there is no within group conflict for countries in either the upper or middle classes of countries based on their level of PCID. The between group conflict does include democracies.

In recent years, considerable concern has arisen over cross-national student’s math achievement. A number of studies focusing on eighth grade student’s math achievement have been published. However, the most important role we should consider is not only students, but also teachers. A good teaching training program could help teachers improve their teaching expertise and student’s math achievement. Moreover, most studies only focused on explained predictions of the effect between potential factors. Therefore, the purpose of this study is to implement a hierarchical linear model and cluster analysis techniques to re-examine the Trends in International Mathematics and Science Study (TIMSS) 2011 among eighth grade students in the United States (U.S.), South Korea, Singapore, and Taiwan. These techniques were applied to provide a teacher characteristics and student math achievement model and identify a new institutional typology based on the pattern of teacher characteristic types and countries. Based on these patterns and model, this study presented the findings, as well as suggestions for improving educational policies and teaching training program in, South Korea, Singapore, Taiwan, and the U.S.

<p>This dissertation is a case study of how two agencies in Umeå, Sweden and Barrie, Canada protect children found in need of child welfare services. The project's purposes are to describe how children are protected from harm in these two contexts, to illuminate the similarities and differences in the child welfare systems reflected at the local level, and explicate the significance of uncovered similarities and differences. The research project is grounded in three complementary theoretical approaches: i) social constructionism, ii) critical program evaluation theory, and iii) institutional ethnography. Using a model I developed to guide cross-national comaprisons, the research project explores three dimensions in the organization and delivery of services: i)Structure (service contexts and features), ii) Intervention (intervention process, and documentation and gatekeeping as two central aspects of intervention), and iii) the interplay between structure and intervention. The project combines methods including focus groups, qualitative application of the vignette technique, and analyses of assessment summaries extracted from case files at each agency. Finding from this investgation are reported in four papers. We identified differences in gatekeeping, use of social work skills, identification of clients, decision-making, and use of compulsory measures and the availability of other measures for clients. The documentation study showed that in Canada documentation is increasingly structured whereas in Sweden documentation is systematically varied but with narrative forms dominating. The different documentation trajectories in these nations are coupled to the paths they have taken with regard to the care and protection of children. We then focus on the "best interests of the child" principle. In Canada, the best interests principle is paramount but intimately connected to "need of protection" and risk assessment. In Sweden, the best interests principle is contibutory to the Social Service Act's emphasis on a solidaristic response to need. When data from this study are taken in context with other research in the field, it appears to give meaning to description of two models of state service for children in need because of abuse or neglect. Umeå is representative of some of the key elements in Swedish child welfare whereas Barrie is representative of some of the key elements in Canadian child protection.</p>
