Entrepreneurial strategies and tactics are often subtle and indiscrete, adding to the mystery of how one goes about being an entrepreneur, particularly within bureaucratic agencies that are often set up to constrain such behaviors. The authors use a case study of the U.S. National Aeronautics and Space Administration (NASA)'s public engagement practices to examine how entrepreneurs shift policy interpretations with administrative agencies. Findings describe three entrepreneurial strategies and tactics: (1) using one-on-one or small group meetings to connect to different audiences across organizations; (2) tying new policy interpretations to existing ones, so changes seem less radical; and, (3) positioning oneself in the middle of the action to control both narrative and progress. Conclusions discuss both practical mechanisms for shifting away from the status quo, and the theoretical contributions to a growing body of literature on strategic and tactical approaches of bureaucratic entrepreneurs in democratic systems. 相似文献

This fourth article of the series is taking an in‐depth analysis at the visible aging of latent fingermarks regarding changes in ridge widths over time. The objective is to quantify and statistically describe significant ridge size variations under controlled indoor conditions. The effect of three environmental variables are examined: type of secretion (sebaceous‐ and eccrine‐rich) and type of substrate (glass and polystyrene) when aged in three light conditions (direct natural light, shade, and dark). Prior to width measurements, fresh and aged fingermarks were powdered with titanium dioxide (TiO2) and sequentially photographed at predetermined times over 6 months. Three independent observers measured the ridges from thirty predetermined locations using strategically placed intersecting lines on the print. Results indicate that fingermarks deposited on glass are more resilient to degradation compared with those deposited on plastic. The presence of direct natural light plays a negligible role on degradation compared to secretion and substrate types. 相似文献

ABSTRACTThis paper surveys the nascent experiments in political ecology underway in predominantly Kurdish areas of south-eastern Turkey, known as Bakûr, and Rojava (northern Syria). The Kurdish freedom movement is attempting to consolidate a social revolution with ecology at its heart in a most unpromising context, given its ongoing struggle against Islamic State and regional embargoes. This greening of its ideology can be significantly attributed to the influence of American social ecologist Murray Bookchin, an inspiration for Kurdish attempts to implement democratic confederalism, which comprises principles of direct democracy, gender equality and ecological well-being in a needs-based economy. The Mesopotamian Ecology Movement has emerged from activist campaigns opposing dam construction, climate change and deforestation in the region, to inform ecology councils tasked with formulating policies that reflect this philosophical paradigm shift. The essay considers the prospects for the ecological initiatives in Turkish and Syrian Kurdistan. It argues that, confronted by formidable challenges, expansion of the democratic confederal model beyond the heartlands of Bakûr and Rojava, and international solidarity, are preconditions for their endurance. 相似文献

Identification of colorants in pigmented pen inks by laser desorption mass spectrometry 总被引:1,自引:0,他引:1
Pigments are rapidly replacing dyes as colorants in pen and printer inks, due to their superior colors and stability. Unfortunately, tools commonly used in questioned document examination for analyzing pen inks, such as TLC, cannot be used for the analysis of insoluble pigments on paper. Laser desorption mass spectrometry is demonstrated here as a tool for analyzing pigment-based pen inks. A pulsed nitrogen laser can be focused onto a pen stroke from a pigmented ink pen on paper, and positive and negative ions representative of the pigment can be generated for subsequent mass spectrometric analysis. Targeted pens for this work were a set of Uni-ball 207 pigmented ink pens containing blue, light blue, orange, green, violet, red, pink, and black inks. Copper phthalocyanine was identified as the pigment used to make both blue inks. A mixture of halogenated copper phthalocyanines were identified in the green ink. Unexpectedly, the pink ink was found to contain a red pigment, Pigment Red 12, treated with a mixture of water-soluble dyes. Each sample yielded ions representative of the pigments present. 相似文献
