新型护角生产技术

针对以废纸和秸秆为主要原料,采用挤出工艺生产的新型护角存在表面粗糙、不美观等缺点,提出了在其表面裹 包粘贴牛皮纸的方案,并设计了牛皮纸裹包护角的工艺路线和设备。通过对护角的托举装置、牛皮纸压痕裁切定位装 置、裹包通道、下压装置和水平推送装置的设计,实现了牛皮纸对护角的全自动裹包。该设计结构紧凑、布局合理、可靠 性高,裹包后的新型护角美观、强度更高。该设计有利于加速实现新型护角的工业化生产。     

走向共识:东西方文化对社会和谐的诉求

和谐是人类文明发展的共同追求,然而不同的历史文化背景塑造了不同的社会和谐理念.从文化形态看,中国传统的集团文化表现出重道德秩序的"人伦型和谐"理念,西方传统的经济文化则是重效率合理性的"知识型和谐"理念.当代中国特色社会主义先进文化是一种新型的集团经济文化形态,呈现出以马克思主义为引领的多文化交融的"开放融合型和谐".     

以发展整合性程序能力为导向的幼儿园科学活动教学策略研究

我国学前科学教育在经历了从知识本位到方法本位，再到当今所倡导的促进幼儿终身发展的人本位的三个阶段。目前实践中传统理念指导的科学教育活动仍普遍存在。以整合程序能力为基本维度，以分析大班《神奇的蛋壳》教学活动“问题呈现—识别和控制变量—下操作定义—形成和验证假设—解释和交流实验过程和结果”等五个方面存在的问题为例，提出以整合程序能力为导向的幼儿园科学活动教学策略。     

Personalisation,individualism and the politics of disablement

This paper assesses the social policy narrative personalisation, and particularly the implications of the narrative for disability politics. The advantages and disadvantages of positioning specific funding mechanisms within the narrative are explored. It is argued that personalisation is insufficiently aligned with collective aspects of empowerment. More particularly, it disproportionately emphasises improvements in individual autonomy through personalised support, and lacks reference to structural oppression or the need for collective forms of action that bring about structural change. It is further argued that personalisation lack a multi-faceted analysis of disability and disempowerment, and as a result also lacks any vision of a positive alternative society. In assessing personalisation, the positive and negative dimensions of disabled people’s freedom are considered. As a response to the apparent shortcomings of personalisation, the integrated living approach and Centres for Independent Living are considered important elements in an alternative narrative to personalisation.     

Ageing Society Issues in Korea*

Korean society is facing unprecedentedly higher population ageing, particularly in the first half of the 21st century. The implications of population ageing have a much wider effect than the welfare of the elderly. From a broader and long‐term perspective, understanding population ageing may require a new paradigm. Korea has attempted to model its policies for ageing society on those of advanced welfare states, but as these no longer seem viable, Korean policy‐makers are searching for more effective and efficient measures to deal with its rapid ageing population. Reflecting a broader and long‐term perspective, the Korean government recently produced a comprehensive national policy plan to deal with the consequences of rapid population ageing. This article outlines the phenomenon of population ageing in Korea and the recent development of national policies for population ageing, describing the Korean comprehensive national policy plan for responding to it and examining major issues and problems related to developing and implementing the plan. This article finally suggests a new, age‐integrated social system approach to an ageing society.     

三螺旋混成组织视阈下的科学知识生产

多价知识观的提出改变了传统的强调科学知识生产过程特定要素或某个片段的视阈,内在地要求以集成性的观点来审视科学组织。在分析知识多价性与科学知识生产场域集成性关系的基础上,阐释了大学—产业—政府三螺旋混成组织是一种科学知识生产的集成性组织。它捕捉了科学知识生产过程中包含学术、市场和政策的多元重叠关系,使科学知识生产所需的资源、组织结构及运作过程都具有集成性特征。     

HAZARD RATE ESTIMATION FOR CENSORED DATA BY WAVELET METHODS

ABSTRACT

We study the estimation of a hazard rate function based on censored data by non-linear wavelet method. We provide an asymptotic formula for the mean integrated squared error (MISE) of nonlinear wavelet-based hazard rate estimators under randomly censored data. We show this MISE formula, when the underlying hazard rate function and censoring distribution function are only piecewise smooth, has the same expansion as analogous kernel estimators, a feature not available for the kernel estimators. In addition, we establish an asymptotic normality of the nonlinear wavelet estimator.     

Mixed Levels of Uncertainty in Complex Policy Models

The characterization and treatment of uncertainty poses special challenges when modeling indeterminate or complex coupled systems such as those involved in the interactions between human activity, climate and the ecosystem. Uncertainty about model structure may become as, or more important than, uncertainty about parameter values. When uncertainty grows so large that prediction or optimization no longer makes sense, it may still be possible to use the model as a behavioral test bed to examine the relative robustness of alternative observational and behavioral strategies. When models must be run into portions of their phase space that are not well understood, different submodels may become unreliable at different rates. A common example involves running a time stepped model far into the future. Several strategies can be used to deal with such situations. The probability of model failure can be reported as a function of time. Possible alternative surprises can be assigned probabilities, modeled separately, and combined. Finally, through the use of subjective judgments, one may be able to combine, and over time shift between models, moving from more detailed to progressively simpler order-of-magnitude models, and perhaps ultimately, on to simple bounding analysis.
