西准噶尔萨吾尔地区地处新疆阿勒泰地区吉木乃县及塔城地区和丰县。酸性侵入岩在区内较发育,其研究对于准噶尔地区后碰撞构造一岩浆演化时限的厘定具有重要的意义。塔斯特岩体是萨吾尔地区重要的复式花岗岩体,与区内铜、金矿化关系密切。塔斯特岩体锆石LA-ICPMS年龄为337±4Ma(1δ),形成于早石炭世。结合已有的地球化学特征研究,这一年龄显示西准噶尔地区在早石炭世已处于后碰撞环境。本文获得的塔斯特岩体成岩年龄是目前在准噶尔地区获得的最老的后碰撞花岗岩锆石U-Pb年龄之一,为准噶尔地区后碰撞构造-岩浆演化时限的厘定提供了新的证据。  相似文献

Who borrows laptop computers in an academic health sciences library? Why do they choose to check out laptops? In a survey, laptop computer users responded that the laptops were used most frequently to do class-related work. Laptops were most often checked out because they could be taken to a quiet area of the library or to where the user had more room to work. The majority of such borrowers were satisfied or very satisfied with the laptops and the service from the library. The majority of those completing the survey were medical school students and graduate students. The circulation of laptop computers at this academic health sciences library is a very successful and popular program.  相似文献

This paper offers a narrative case study of Mirabel, one participant in a digital storytelling workshop for women who were newcomers to Canada, whose experience compelled me to rethink conceptualizations of participation in social justice-oriented, community-based participatory media projects. Drawing on the work of Sara Ahmed, I consider how Mirabel’s resistance to the ‘promise of happiness’ offered by the group was interpreted by others as a failure to participate. Conversely, I suggest that Mirabel’s experience and her digital story are generative for thinking about resistance as a method of participation and a political resource for the group. I argue that conceptualizations of participation should be complicated to include the kinds of agency demonstrated by participants like Mirabel who resist the norms of the digital storytelling workshop and group culture.  相似文献

The debate about whether the arts should be supported or not is far from new, and most governments support the arts in one way or the other. The literature considers several arguments in favor of such interventions. Public education may seem to be an action which could, in the long run, lead to possible reductions of subsidies. Surveys show that those who have been exposed to the arts when young participate more when adult. However, the “non-market” transmission from parents to children generates an external effect, which has to be taken into account to reach first-best situations. We construct an overlapping generations model in which young consumers are exposed to both public education toward the arts and to non-altruistic transmission of such a taste from their parents. We show that the first-best can be reached only if there is both public cultural education and subsidization of arts consumption. Therefore, education cannot be considered as a substitute for subsidies to arts consumption. However, as is often the case in European countries, government intervention is usually below the first-best level. Using a model calibrated on French data, we show that it is then preferable to subsidize education, while consumption, especially of the older generations, should be taxed rather than subsidized.

ABSTRACT

Relying on Marianne Hirsch’s work on postmemory, as well as theories about new media and memory, this study explores how a group of Armenian young adults in Toronto remember the Armenian Genocide from afar, 100 years after it happened. The data come from 100 Voices: Survival, Memory, Justice. Through a thematic and visual analysis of a sample of video clips posted on YouTube, this study argues that 100 Voices is a work of postmemory that stands at the intersection of prevailing ethno-nationalist constructions of Armenian identity on the one hand, and universal discourses of human rights and historical justice, on the other. Participants are positioned as the Armenian youth, performing a particular duty of memory to remember the genocide and transmit genocide memories to future generations. At the same time, 100 Voices enables these youths to emerge as activists who express their group-based claims through universal parameters of claim-making.  相似文献

IntroductionTwo new formulas, the Martin-Hopkins and the Sampson formula, were recently developed to overcome shortcomings of the Friedewald formula for calculating LDL-cholesterol. We aimed to compare the concordance of the two formulas with apolipoprotein B (apoB), a surrogate marker of the number of LDL particles.Materials and methodsIn a study of serum lipid data of 1179 patients who consulted the AZ St-Jan Hospital Bruges for cardiovascular risk assessment, the correlation and concordance of the Friedewald, Martin-Hopkins and Sampson formulas with apoB concentration, measured by immunonephelometry, were determined and compared.ResultsThe Martin-Hopkins formula showed significantly higher correlation coefficient than the Friedewald formula with apoB in the entire dataset and in patients with low LDL-cholesterol < 1.8 mmol/L. Both Martin-Hopkins and Sampson formulas yielded > 70% concordance of LDL-cholesterol with regard to treatment group classification based on population-equivalent thresholds of apoB in hypertriglyceridemic patients (2-4.5 mmol/L), with the highest concordance (75.6%) obtained using Martin-Hopkins formula vs. 60.5% with Friedewald formula.ConclusionThe Martin-Hopkins (and, to a lesser extent, Sampson) formula is more closely associated with the number of LDL particles than Friedewald formula. This, in combination with literature evidence of lesser accuracy of the Friedewald formula, is an argument to switch from Friedewald to a modified, improved formula.  相似文献

This study explored the relationship between metacognition and intelligence in a group of normal adolescents. The relationship has strong theoretical support in current conceptions of intelligence. For the purposes of this study metacognition was assessed across three different cognitive problem sets. Correlational analyses indicated a nonsignificant relationship between intelligence and metacognition. These results suggest that tests of metacognition and intelligence may tap unrelated aspects of cognition and that additional research will be required to understand the relationship between these two constructs.  相似文献
