Hearts of Darkness: white women write race

Abstract

In an effort to popularise the gas stove, boost sales and minimize the genuine and perceived dangers of using this volatile domestic appliance, late Victorian gas managers and stove manufacturers employed female cookery teachers to perform public demonstrations at trade exhibitions throughout the country. Eventually, these women comprised a special department of gas sales, calling directly on customers in their homes to offer personal instruction in the proper use and care of gas stoves. Part social workers, part salesgirls, the ‘lady demons’, short for lady demonstrators, moved between the traditionally gendered separate spheres of work and home, consciously constructing a professional image that reconciled the social tensions of this new occupation. They offer an early example of women's entrance into the corporate business world, the feminisation of consumption, and the combination of customer service with social welfare.     

War Hypotheses: Drug Trafficking,Sovereignty and the Armed Forces in Mexico

This essay analyses how Mexican presidents have interpreted the concepts of drug trafficking and national security and how these particular connotations have redefined national sovereignty and the specific role of the armed forces in protecting this sovereignty. A qualitative technique of discourse analysis is used to examine public speeches by Zedillo (1994–2000), Fox (2000–2006) and Calderón (2006–2012). The conclusions suggest that drug trafficking and US omnipresence are the two main issues that shaped Mexico's national security threats during this period, with qualitatively distinct trajectories.     

Puerto Rico: National security,economic growth and colonialism

Abstract

Puerto Rico's significance for the US state and imperialism has gradually deteriorated. In the context of recent global changes and new developments in the US political economy the logic that justified colonial control cannot be sustained. However, an array of counteracting political and economic forces are conspiring to overcome the altered material and geopolitical conditions that make evident the need for Puerto Rico's decolonization.

Colonialism has given rise to an array of forces that impedes any changes in Puerto Rico's formal political status. Where once the US state, corporate capital and the dominant political forces in Puerto Rico were in relative agreement on sustaining the colonial enterprise, a new constellation of competing forces has emerged. Within Puerto Rico proponents for the status, quo and those who agitate for statehood have reached virtual electoral parity. Monopoly “capital, primarily in Pharmaceuticals, dominates the local economy. However, it is challenged by North American unions and their congressional allies who seek to rescind the lucrative fiscal policies that account for these firms exorbitant profits. Agencies of the US state and congressional committees are at odds on what needs to be done to sustain an unmanageable, increasingly expensive and anachronistic colony.

This essay presents a framework for examining the array of forces and conditions that continue to erode the colonial relation and that explains colonialism's fragility in the current period of global readjustment.     

Portable high‐resolution automated 3D imaging for footwear and tire impression capture

The forensic science community raised the need for improved evidence recognition, collection, and visualization analytical instrumentation for field and laboratory use. While the 3D optical techniques for imaging static objects have been extensively studied, there is still a major gap between current knowledge and collecting high‐quality footwear and tire impression evidence. Among optical means for 3D imaging, digital fringe projection (DFP) techniques reconstruct 3D shape from phase information, achieving camera‐pixel spatial resolution. This paper presents a high‐resolution 3D imaging technology using DFP techniques dedicated to footwear and tire impression capture. We developed fully automated software algorithms and a graphical user interface (GUI) that allow anyone without training to operate for high‐quality 3D data capture. We performed accuracy evaluations and comparisons comparing with the commercial high‐end 3D scanner and carried out qualitative tests for various impressions comparing with the current practices. Overall, our technology achieves similar levels of accuracy and resolution with a high‐end commercially available 3D scanner, while having the merits of being (1) more affordable; (2) much easier to operate; and (3) more robust. Compared with the current practice of casting, our technology demonstrates its superiority because it (1) is non‐destructive; (2) collects more evidence detail than casts, especially when an impression is fragile; (3) requires less time and money to collect each piece of evidence; and (4) results in a digital file that can easily be shared with other examiners.
