石油、天然气等非再生能源供给约束对经济发展的制约,使人类开始探索第三次能源变革。伴随每次能源结构变革是现代产业发展的巨大变化,后者又进一步推动经济社会发展。北京致力于世界城市建设,其经济社会发展要形成国际影响力与控制力,其顺应能源发展趋势的合理产业布局至关重要,而首都西南区域目前正处于传统产业退出、接续产业尚未形成时期,如果利用后发优势,建立国家战略性新兴能源产业基地,将可能实现区域经济的跨越式发展。  相似文献

Suspects in shooting investigations in Chicago are routinely transported in department vehicles and detained in department facilities prior to gunshot residue (GSR) evidence collection. The GSR test results are used to associate the suspect with primary exposure to GSR. The potential for these vehicles and facilities being sources of secondary GSR contamination needed to be determined. A total of 201 samples were collected from randomly selected vehicles and detention facilities. The sampling collected trace materials from surfaces that suspects' hands may contact during the arrest process. These samples were examined for the presence of GSR particles using scanning electron microscopy. Upon completion of the automated analysis, those particles that met an initial GSR screening criterion were relocated and reanalyzed. The locations where GSR particles were recovered allowed us to make recommendations to the Chicago Police Department with regard to transporting and detaining these suspects. The low number of GSR particles recovered suggests that the potential for secondary contamination, although present, is relatively low.  相似文献

With a focus on India, and drawing on critical scholarship on geo-politics and geo-economics and “relational” state theories, this article examines the ways in which ideational and material processes of state transformation have shaped India’s international engagement in different periods. Prior to 1991, geo-political social forms linked to a national developmentalist state project shaped India’s engagement with global and regional multilateralism and the nature of this engagement fluctuated according to shifts in the legitimacy and viability of this state project. The erosion of the developmentalist state project from the 1970s laid the path for a deeper shift in the national social order in the 1990s with the recasting of statehood wherein India’s future was thought to be best secured through policies of economic openness, growth and competitiveness. This shift in India’s state project has given rise to new forms of global and regional engagement that are distinct to older forms of international engagement and reflect and further processes of state transformation in India. This is illustrated through a case study on energy policy.  相似文献

ABSTRACT

This is Part 1 of an article arguing for an extended application of Karl Marx’s insight that the apparent reciprocity of free market exchange is to be understood as an ideology that obscures material processes of exploitation and accumulation. Rather than to confine this insight to the worker’s sale of his or her labor-power for wages, and basing it on the conviction that labor-power is uniquely capable of generating more value than its price, the article argues that capital accumulation also relies on asymmetric transfers of several other biophysical resources such as embodied non-human energy, land, and materials. It proposes that the very notions of “price” and “value” serve to obscure the material history and substance of traded commodities. Such a shift of perspective extends Marx’s foundational critique of mainstream economics by focusing on the unacknowledged role of ecologically unequal exchange, but requires a critical rethinking of the concept of “use-value.” It also suggests a fundamental reconceptualization of the ontology of technological progress, frequently celebrated in Marxist theory. Part 1 of the article introduces the argument on unequal exchange, the ideological function of money, some concerns of ecological Marxism, and the conundrum posed by three contradictory understandings of “use-value.”  相似文献

This study investigated and evaluated the safety margins of the continuous long duration (up to 30 min) effect of the TASER X26 waveform, using a Sus scrofa model. Long duration continuous stimulus has not been evaluated on humans or human surrogates prior to this study. Swine were used as models due to similarities with humans in their skin and cardiovascular systems. Very long duration was used to determine both exposure dose and possible adverse physiological effects of dose. The trial began with an application of 10 min, and subsequent animals received increasing exposure time up to a survived maximum duration of 30 min. At the onset of this work, it was hypothesized that there would be a time limit after which most animals would not survive consistent with increased dose response. However, this hypothesis was not supported by the experimental results. All animals (10 of 10) survived up to 3 min. Seven of the 10 animals survived up to a 10‐min exposure and 3 of 5 animals with a 30‐min target exposure survived the full exposure. Surviving animals were recovered and observed for 24 h, with no postrecovery deaths. This suggests that swine (based on physiology) will not experience a fatal event when exposed to the TASER X26 for a continuous 3 min. Conclusions regarding longer duration (10–30 min) are not as certain due to the small sample sizes at these time intervals.  相似文献

Raman spectroscopy has found increased use in the forensic controlled substances laboratory in recent years due to its rapid and nondestructive analysis capabilities. Here, Raman spectroscopy as a screening test for methamphetamine in clandestine laboratory liquid samples is discussed as a way to improve the efficiency of a laboratory by identifying the most probative samples for further workup among multiple samples submitted for analysis. Solutions of methamphetamine in ethanol, diethyl ether, and Coleman fuel were prepared in concentrations ranging from 0.5% to 10% w/v, and Raman spectra of each were collected. A concentration‐dependant Raman peak was observed at 1003 per cm in each solution in 4% w/v and greater solutions. Case samples were analyzed and also found to reliably contain this diagnostic peak when methamphetamine was present. The use of this diagnostic indicator can save the forensic controlled substances laboratory time and materials when analyzing clandestine laboratory liquid submissions.  相似文献

This article deals with layoff survivor's syndrome following the 1997 economic crisis in South Korea. South Korea has been credited with quickly recovering from its economic crisis by implementing policies aimed at economic restructuring. However, researchers have discovered that, in addition to those directly affected by a lay-off, layoff survivors as well suffer from impacts on their mental health — hence the name, layoff survivors' syndrome. The present research focuses on the socio-psychological impact of downsizing on layoff survivors on the basis of a nationwide survey. The findings reveal a significant difference in work attitudes after downsizing, as well as a significant impact on survivors' mental health. The study concludes that these negative impacts may negatively influence organizational productivity, and thus downsizing as a blanket strategy for organizational renewal needs to be reconsidered.  相似文献

Abstract: High‐energy synchrotron radiation x‐ray fluorescence spectrometry (SR‐XRF) utilizing 116 keV x‐rays was used to characterize titanium dioxide pigments (rutile) and automotive white paint fragments for forensic examination. The technique allowed analysis of K lines of 9 trace elements in 18 titanium dioxide pigments (rutile), and 10 trace elements in finish coat layers of seven automotive white paint fragments. High‐field strength elements (HFSE) were found to strongly reflect the origin of the titanium dioxide (TiO2) pigments, and could be used as effective parameters for discrimination and classification of the pigments and paint fragments. A pairwise comparison of the finish coat layers of seven automotive white paint fragments was performed. The trace elements in the finish coat layers detected by the high‐energy SR‐XRF were especially effective for identification. By introducing the trace element information of primer and electrocoat layers, all the automotive white paint fragments could be discriminated by this technique.  相似文献
