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.

A lack of method to find out the fairness limit of fuel consumption in mining operations enables statistical approach with two-tail test be applied to observe the fairness limit of actual fuel oil consumption compared to the manual handbook of its equipment. Fuel consumption according to the manual handbook for EXCA LIEBHERR 9350 excavator is 207.23 liters/hour and EXCA HITACHI 2500 is 191.51 liters/hour, while CATERPILLAR 777D Dump Truck is 36-53 liters/hour consider as low, 53-73, 8 liters/hour medium, and 73.8-96.5 liters/hour as high. This statistical approach has been carried out after fulfilling the concept of mechanized earth-moving. As a result, the differences in fuel consumption of LIEBHERR 9350 and HITACHI 2500 are 3.72% and 3.26%, which are still in range of a reasonable fuel consumption limit, while CAT 777D operating on LIEBHERR 9350 and CAT 777D operating on HITACHI 2500, each shows a difference in fuel consumption. The differences are 29.65%, meaning that it has exceeded the reasonable limits of fuel consumption and 7.15%, meaning that it is still in range of a reasonable fuel consumption limit.

This chapter explores how colonists in seventeenth-century New England used gender ideologies about women’s roles as actors in public spheres to frame their understanding of women who fought in the region’s wars. The chapter explores this idea from three different angles. First, it examines how New England’s colonies incorporated women’s martial activities into their colonization strategy, sometimes even requiring women to remain in remote fortified towns, living in garrison houses that simultaneously served as military and household spaces. Second, it looks at how Native women participated in the region’s wars as leaders (sachems), spies, combatants, and in ritual torture. The chapter investigates how English politicians used their own concepts about women’s public roles to shape their ideas about Native female combatants. This section also features a case study of Weetamoo of the Pocasset, a prominent female sachem who died while leading an anti-colonial coalition in King Philip’s War (1675-76). Third, the chapter explores how English women attempted to shape military and colonial policy through mob violence.

In 2014, the Australian Petroleum Production and Exploration Association (APPEA) published the ‘Method to assist titleholders in estimating appropriate levels of financial assurance for pollution incidents arising from petroleum activities’, referred to as the APPEA Method. The APPEA Method provides a standard approach to quantifying the appropriate level of financial assurance required under the Offshore Petroleum and Greenhouse Gas Storage Act 2006 (OPGGS Act). The National Offshore Petroleum Safety and Environment Management Authority (NOPSEMA) endorsed the APPEA Method for an initial period of 2 years (until December 2016) with the requirement that APPEA review the method against a broader range of case studies to confirm its validity. In 2017, APPEA applied the APPEA Method to 18 case studies, comparing independently calculated cost estimates with the APPEA Method cost band for each case study. For 17 of the 18 case studies, the independent cost estimate was less than the APPEA Method cost band, confirming the validity of the APPEA Method for those case studies. For one of the case studies involving marine fuel oil, the APPEA Method cost band potentially underestimated the response and clean-up costs. The robustness of the APPEA Method can be improved by amending the hydrocarbon type impact score for fuel oils. Based on the review, NOPSEMA has since endorsed the APPEA Method until September 2018. The APPEA Method is currently endorsed for incidents in which the total volume of hydrocarbon released is <1 000 000 m3 and the total volume of oil ashore is <25 000 m3. Based on an assessment of the response and clean-up costs from three additional case studies that exceeded these limits, amendments to the APPEA Method are proposed that would extend the range of incidents to which it could be applied.

Even as the concept of terroir becomes more salient in diverse cultural and national contexts, climate-driven environmental change threatens to alter the ecologies that contribute to the distinctive terroir of place-based products. Yet few studies examine how producers of terroir products perceive and experience environmental change. Our comparative case study addresses this gap, as we examine ways that changing ecological conditions will influence the emergent terroir of Wisconsin artisanal cheese and New England oysters. Drawing on in-depth interviews and a survey, we describe the environmental and sociocultural elements that Wisconsin artisanal cheesemakers and New England oyster farmers identify as characteristic of the terroir and merroir (terroir’s maritime adaptation) of their products. We then compare cheesemakers’ and oyster farmers’ perceptions and experiences of climate change. We find that both groups perceive climate-related threats to the terroir and merroir of their products, though each group experienced these threats differently. We argue that the ongoing constitution of terroir—which has always reflected a tension between nature and culture—will be further complicated by changing ecologies. We suggest that a generative understanding of terroir that emphasizes terroir’s sociocultural dimensions may help artisanal cheesemakers and oyster farmers mitigate some climate-related threats to their products.
