Trigger levels for fine suspended sediment (FSS) load in streams are required to identify rainfall-runoff events that have significantly elevated FSS loads, compared with expected background loads, as a result of catchment disturbance. Stream FSS load data collected in the mine-impacted Magela Creek catchment in the wet-dry tropics were used to derive water quality management trigger levels for two approaches – a Before-After-Control-Impact Paired difference design (BACIP) and a regression relationship between observed FSS load and corresponding event discharge characteristics. The results indicate that both the BACIP and regression relationship approaches behave similarly, with similar FSS load events elevated above trigger levels. Notwithstanding this, it is recommended that in order to reliably assess the location and magnitude of a catchment disturbance on FSS load, a combination of BACIP and regression relationship approaches must be adopted. In this study, an event with a FSS load above trigger levels associated with both BACIP and the regression relationship fitted for the downstream site is considered to be significantly elevated as a result of a disturbance within the mine-impacted region. While this technique cannot conclusively determine whether the cause of the disturbance is mine-related or natural (such as fire or bank erosion), it is an efficient statistical method of identifying events that warrant further investigation and management action, if required. 相似文献

The school formal in New Zealand constitutes a rich site of analysis for researchers interested in gender and sexuality performances. As a social space, the formal both shapes bodies and is shaped by them. In this article, we explore the school formals of three different types of schools: a single sex girls’, a single sex boys’ and a co-ed. high school, all from an urban centre. Using the theoretical tools provided by poststructuralism and queer theory, we conducted a discourse analysis of observations conducted by the first author at two school formals, interviews with staff and students and interviews with peer researchers. We demonstrate how same-sex practices do not necessarily map onto queer bodies, masculinity onto ‘male’ bodies or femininity onto ‘female’ bodies. Such fluidity challenges the rigid heterosexual/homosexual and masculine/feminine binaries so that schools are more inclusive of gender and sexual diversity. 相似文献

1958年,农业中学最先诞生于江苏省.在"大跃进"运动的影响下,江苏省农业中学的学校数量及在校人数迅速膨胀,成为全国教育"大跃进"的一个重要组成部分和表现形式.在整个"大跃进"时期,江苏省的农业中学始终保持了一个庞大的规模,直到中共中央决定对国民经济实行"调整、巩固、充实、提高",其盲目发展的势头才得以遏制并开始逐步调整. 相似文献

This paper has two aims: to explore approaches to the measurement of children's daily travel to school in a context of limited geospatial data availability and to provide data regarding school choice and distance travelled to school in Soweto-Johannesburg, South Africa. The paper makes use of data from the Birth to Twenty cohort study (n?=?1428) to explore three different approaches to estimating school choice and travel to school. First, straight-line distance between home and school is calculated. Second, census geography is used to determine whether a child's home and school fall in the same area. Third, distance data are used to determine whether a child attends the nearest school. Each of these approaches highlights a different aspect of mobility, and all provide valuable data. Overall, primary-school-aged children in Soweto-Johannesburg are shown to be travelling substantial distances to school on a daily basis. Over a third travel more than 3 km one way to school, 60% attend schools outside of the suburb in which they live, and only 18% attend their nearest school. These data provide evidence for high levels of school choice in Johannesburg-Soweto, and that families and children are making substantial investments in pursuit of high-quality educational opportunities. Additionally, these data suggest that two patterns of school choice are evident: one pattern involving travel of substantial distances and requiring a higher level of financial investment and a second pattern involving choice between more local schools, requiring less travel and a more limited financial investment. 相似文献

Innovative curriculum frameworks that support children as active researchers and designers in everyday learning contexts remain unprioritized in school settings. Design literacies challenge and expand existing curriculum structures at a time when state and national curriculum privilege literacy and numeracy testing. Drawing on a broader ethnographic study that examined children's inhabitation of school food gardens through pedagogies of food production, ecology and design in three Australian primary schools [Green, M. 2011. “Place Matters: Pedagogies of Food, Ecology and Design.” Unpublished PhD, Monash University Churchill Victoria], this paper focuses on the design literacies or ‘design-centered pedagogy’ [McLaren, S. 2008. “Learning for Engagement: Lose the Ring-Fencing.” Paper presented at the Technology Education Research Conference: Exploring Technology Education: Solutions to Issues in a Globalised World, Gold Coast, Queensland] that supported children's engagement with everyday learning in one school community. Semi-structured and ‘walking interviews’ provide rich data for understanding the contributions of design and design processes in a garden-based curriculum. When linked to a framework of sustainability, design literacies can expand learning opportunities that deepen their connection to everyday places. 相似文献

This article investigates the policy feedback and political learning effects of school vouchers. Of particular interest is how market‐based policies affect the likelihood that program participants will connect their experiences with the policy to the government. I examine parent survey data from an evaluation of the Milwaukee school voucher program. I find that voucher parents are more likely than public school parents to perceive that the government has influenced their child's schooling and to believe that their experiences with their child's school have taught them about how government works. Further, voucher parents report that their experiences with the policy have made them more politically active. While majorities of voucher and public school parents support increased public school expenditures, there is some evidence that school vouchers may decrease support for public schools. 相似文献

现代新儒家之一的熊十力创造了以"体用不二"本心论为核心的哲学体系。他通过科玄之辨,明示哲学为究体之学,且破立结合,通过批驳西学、道家和大乘空有二宗,最终构建起"体用不二"本心论这一哲学本体论。这样熊氏就会通中外,熔融古今,揭橥其本体哲学的逻辑架构,昭示了其哲学缜密的思维逻辑论证过程。 相似文献

In this paper I have two objectives. The first is to critically explore definitions of playing that have underpinned a great deal of research in children's geography. In so doing I want to highlight some of the assumptions that various authors within geography have made (often implicitly) about the ontological status of playing. This will in turn, lead me to work with, between and sometimes against three authors who have tried to theorize playing. In following this route, I hope to come to some tentative conclusions about the status of playing, which paradoxically will eschew any (strong) ontological commitment at all. This leads to my second objective, which is to explore four particular aspects of playing—embodiment, affect, objects and time-space—to examine how they are interleaved with spaces and spacing. In necessarily situating this work within my research at Hilltop Primary School1 in the summer of 2001, I hope to show that geographical studies can contribute to definitions of playing as much as playing can inflect certain notions of space. 相似文献

英国新社会史思潮的兴起及其整体社会史研究的国际反响 总被引:2,自引:0,他引:2
“新社会史研究”作为一种史学新思潮,与西方史学的整体化趋势,几乎同时出现于现代国际史学舞台。英国新社会史思潮具有广泛和深刻的国内外史学渊源。英国新社会史学派宣扬的核心问题是坚持“自下而上”史学观念,它彰显了由此观念指导下的整体社会史取向和研究实践。从较广泛的分析角度看,在国际史学发展格局重新调整的现时背景下,英国马克思主义新社会史学派引起国内外史学界的广泛注意和效仿。它对国际史学发展的推动性作用是不可忽视的,这集中体现了该学派及其整体史学研究的国际反响。 相似文献
