In the world of K–12 education, the growing numbers of dropouts are a major concern. This article examines the dropout rates of Chinese and Vietnamese high school students. Using logistic regression analysis, this article examines the influence of ethnicity, gender, and socioeconomic status (SES) on dropout rates. The distinct contribution of this analysis lies within the intraethnic comparisons within the Asian American student population and its use of longitudinal data. The results of the study support existing research that gender and SES are related to dropout rates. Moreover, an interesting interaction between ethnicity and SES exists.

Procedure Model

This work proposes a procedure for simultaneous parameters identifiability and estimation in metabolic networks in order to overcome difficulties associated with lack of experimental data and large number of parameters, a common scenario in the modeling of such systems. As case study, the complex real problem of parameters identifiability of theEscherichia coliK-12 W3110 dynamic model was investigated, composed by 18 differential ordinary equations and 35 kinetic rates, containing 125 parameters. With the procedure, model fit was improved for most of the measured metabolites, achieving 58 parameters estimated, including 5 unknown initial conditions. The results indicate that simultaneous parameters identifiability and estimation approach in metabolic networks is appealing, since model fit to the most of measured metabolites was possible even when important measures of intracellular metabolites and good initial estimates of parameters are not available.

The development of student civic engagement has featured in Indian educational policies for decades as a critical goal of schooling. However, the narrowness of the prescribed K-12 curricula, and the intense focus on competitive exams, do not support such an outcome. To overcome this problem, ABC School in India decided to pilot service-learning in its middle-school classroom. The idea was to assess the effects of such a program on students and the community’s welfare. Analysis of data from surveys, focus groups, and interviews showed that the service-learning project might have supported increased civic engagement in some students while also enhancing the welfare of the community served. No prior peer-reviewed empirical studies have been published on the nature and effects of service-learning at schools in India.

A complicated puzzle: spinsters, widows and credit in Sweden (1790–1910)

This article aims to retrace the extent of single women's engagement in the credit market. To this end, it relies on a series of more than 1,900 probate inventories drawn up between 1790 and 1910 in the two Swedish cities of Gävle and Uppsala. These two cities represent an ideal case study, because the process of industrialisation and economic development resulted in two differently structured credit markets. The research centres initially on the problem of studying women's agency from probate inventories. It analyses the main characteristics of spinsters and widows as they emerge from the sources and compares them with married women. Subsequently, the article analyses how marital status shaped women's economic lives, affecting how they participated in the credit market. For this purpose, it focuses specifically on banking and peer-to-peer exchanges (in particular, promissory notes). Spinsters favoured more conservative strategies relying more often on the services provided by banks, while widows seemed to have played an additional, and more significant, role as lenders in peer-to-peer networks. The study also confirms that unmarried women were only rarely active as borrowers.
