日本现代化的人口条件

现代化之初,日本的人口有四个基本特征,即高密度、低增长率、低依赖性人口和高素质。高密度的人口是日本现代化的不利因素,如何化不利为有利是日本现代化的关键,而低增长率、低依赖性人口和高素质则是日本经济起飞的重要条件。

Aboriginal Performance on Standardized Tests: Evidence and Analysis from Provincial Schools in British Columbia

Many indigenous populations are experiencing rural-to-urban migration. In making this transition, indigenous peoples are entering industrial societies where most income derives from wages or salaries, and formal educational achievement is crucial in determining economic prospects. This research analyzes the gap in test score results between Aboriginal and non-Aboriginal students in public schools in the Canadian province of British Columbia. It finds a strong effect of school quality, as measured by non-Aboriginal achievement, on Aboriginal achievement. It also finds a nonlinear negative relationship between Aboriginal achievement and the number of Aboriginal students in a school over the empirically observed range. It thus suggests a possible trade-off and dilemma between, on the one hand, policies that enable Aboriginal students to concentrate in a few schools able to provide a culturally sensitive curriculum and, on the other, policies to maximize Aboriginal academic achievement.

Meteorological influences on the spatial and temporal variability of NO2 in Toronto and Hamilton

The spatial and temporal variability of nitrogen dioxide (NO₂) concentrations and their relationships with meteorology was evaluated in the Toronto–Hamilton urban airshed. NO₂ concentrations were highest in the early morning and late evening. Mean concentrations were highest in winter, although individual one-hour NO₂ concentrations were found to be highest in summer. Wind direction was the strongest control on hourly NO₂ concentration, and temperature and wind speed also had an effect. Our analysis of NO₂ concentration variation by wind direction showed that areas downwind of major highways, urban centres and industry were exposed to higher pollutant concentrations. Seasonal patterns of NO₂ concentration displayed significant spatial heterogeneity, in particular, in Toronto. Onshore winds sheltered coastal inhabitants from the full extent of NO₂ exposure they would otherwise experience. Seasonal variations in meteorology and emissions mean that the degree of spatial variability in NO₂ concentrations changes from season to season. This study will help to improve existing land-use regression-based NO₂ prediction models by incorporating meteorological controls on NO₂ distributions for health effect studies.     

Raw material quality and Oldowan hominin toolstone preferences: evidence from Kanjera South,Kenya

The role of raw material quality in Oldowan technology has not been fully explored. There are numerous studies suggesting Oldowan hominins preferred certain types of stone for artifact manufacture. Previous studies of the artifact assemblage from the early Pliocene Oldowan locality of Kanjera South (South Rachuonyo District, Kenya) show that raw material selection and transport was an important aspect of Late Pliocene hominin adaptations. Yet the exact properties of stones that hominins were selecting remain enigmatic. Two potentially important features of artifact raw material are durability and fracture predictability. We investigate fracture predictability through mechanical tests of stone and investigations of the affect of stone properties on fracture patterns in archaeological collections. We investigate stone durability with actualistic studies of edge attrition combined with further mechanical tests of various lithologies. Oldowan hominins at Kanjera appear to have selected raw materials based on their durability. The ability for a stone to fracture consistently does not appear to be as important in hominin toolstone preference as previously assumed. Hominins that produced the assemblages at Kanjera South appear to have incorporated an extensive understanding of various attributes of raw material in the transport and production of stone artifacts. When combined with previous research on the transport patterns at Kanjera, the results of this study provide evidence for a more complex raw material acquisition strategy than has previously been suggested for Late Pliocene Oldowan hominins.     

Too late to buy a home? School redistricting and the timing and extent of capitalization

In the past 50 years, a voluminous literature estimating the value of schools through capitalization in home prices has emerged. Prior research has identified capitalization using a variety of approaches including discontinuities caused by boundaries. Here, we use changes in school boundaries and the opening of a new school in Fayette County (Lexington), Kentucky to identify this capitalization. Critical to properly estimating the effect of redistricting is to account for when information on redistricting is available. We treat the information about the effects of zoning as occurring in three stages: announcement of the intent to open the new high school and redistricting, approval of the specific redistricting plan (map), and implementation (opening of the new high school and actual changes in boundaries). We find significant changes in values for homes redistricted from lower-performing schools and we find that this capitalization occurs well before implementation of the redistricting. As we show, failure to account for capitalization occurring before implementation will attenuate and even change the sign of capitalization.     

信息定位型展览:提升中国博物馆品质的契机

信息定位型展览以博物馆的综合素质为基础,涉及到博物馆的收藏政策,藏品研究的深度与系统性,展览组织的合理性,展览的传播技术及与展览相关的辅助教育等。只有各个环节都符合科学的要求,才有可能建造观众喜欢看、看得懂,能得到启迪与教益的展览。因此,应以信息定位展览的建设为契机,确立以"保存社会记忆"为核心价值观的收藏政策;加强藏品研究,为信息定位型展览提供学术支撑;建立合理的程序与标准,开展展览评估,打造具有良好传播能力的展览;拓展深化传播效果,开展丰富的公众教育活动,从而从根本上提高当代博物馆的品质。
