A RESIDENTIAL ENERGY MARKET MODEL: AN ECONOMETRIC ANALYSIS*

This paper develops a multisector residential energy policy model. This model hypothesizes that household energy behavior is affected by conditions in the housing, the mortgage finance, and the energy markets. The relationships encompassed by the model are specified with 32 single and simultaneous equations and tested with quarterly data drawn from behavior in Delaware. After the testing and evaluation of the model for its statistical performance, thereafter, three energy policies are simulated a 5 percent residential energy consumption tax, a set of conventional insulation requirements for all new housing, and a passive solar-installation requirement for all new housing. These policy choices are evaluated in terms of their impact on energy consumption, prices, demand and size of different types of housing permits, and mortgage financing. Finally, the economic and social implications of these policy impacts are discussed.     

OBTAINING AN UNDERSTANDING OF ENVIRONMENTAL KNOWLEDGE: WENDABAN STEWARDSHIP AUTHORITY

A method for obtaining an understanding of people's environmental knowledge and values and the major findings are discussed. A participatory mental mapping exercise method was used with the Teme-Augama Anishnabai and non-indigenous, government-appointed members of the Wendaban Stewardship Authority in Temagami, Ontario. Analytical categories were permitted to 'emerge' from the data obtained, rather than being imposed by the researchers. The findings demonstrate that the Teme-Augama Anishnabai perceive the land in a more complex, more detailed way than do the non-indigenous people. Both groups, however, are concerned with maintaining the quality of the environment in which they live, but there are differing bases for such concerns0

LEAD ISOTOPE APPROACH TO THE UNDERSTANDING OF EARLY JAPANESE BRONZE CULTURE

For several years, the authors have used lead isotope analysis to investigate extensively the provenance of ancient bronze or copper artifacts which had been excavated mainly from Japanese archaeological sites. The results have been published item by item in several relevant Japanese journals. This review is intended to give an account which will review the whole work relating early Japanese bronze culture to Chinese and Korean cultures through lead isotope study.     

城市和区域产业发展分析的增长商测度

区域产业分析的常用测度之一是区位商,该测度用于一个地理单元（如北京市）中某种行业在全部行业中的比重与特定区域（如全中国）的同种行业比重做比较。然而,区位商是一个静态概念,不能反映一种行业的相对增长幅度或者变化速度。基于数学中"商"的概念和理论地理学中测度构造的一般方法,本文定义了一个行业增长商测度,用于比较一个子区域中某种行业的增长幅度与特定地理区域中同一行业增长幅度,数值越大表明一个子区域的某种行业相对于特定区域的同种行业的增速越快、增幅越大。进一步地,定义了一个区域增长商,用于比较某种行业的相对增幅与全部行业的平均增幅,数值越大表明某种行业在全部行业中的增速越快。采用信阳实例说明了增长商分析的应用方法。作为参照,定义、对比并讨论了区位熵和增长熵测度。增长商是一个动态的测度,简明易懂,在区域产业分析中可以与区位商功能互补,在未来的主导产业选择中可能发挥一定作用。     

THE DOUBLE-AXE: A CONTEXTUAL APPROACH TO THE UNDERSTANDING OF A CRETAN SYMBOL IN THE NEOPALATIAL PERIOD

The Double-Axe has always been considered as one of the most important religious symbols in Minoan Crete. This paper reassesses the significance of the Double-Axe and puts forward a new interpretation for it. It recognizes the great potential for change in symbolic meanings during the Bronze Age and seeks to understand the Double-Axe in as narrow a period as is realistically possible by filtering out evidence from other periods. Central to the argument is the principle that the meaning of symbols is contextually dependent. It builds, therefore, a new interpretation of the Double-Axe on the basis of as wide a range of contextual associations as possible, both within iconographic sources and in the wider material record. From these contextual associations, it suggests that in the Neopalatial period the Double-Axe was a symbol primarily associated with a social group which exercised power in the economic, military and religious realms and that it became a solely religious symbol only later.     

RETENTION OF PHOSPHATE IN BURIED CERAMICS: AN ELECTRON MICROBEAM APPROACH

Elevated concentrations of P₂O₅ of 2–12 wt% absolute were observed in the matrices of a small group of ceramics with the electron microprobe. P₂O₅, CaO and FeO^t are enriched towards the surfaces in some cases and elemental correlations suggest precipitation of a crystalline calcium phosphate with a stoichiometry close to CaO · P₂O₅. Scanning electron microscopy with X-ray mapping showed P₂O₅ to be dispersed in the ceramic matrix on a very fine scale, while X-ray diffraction detected no crystalline phosphate. Parallels are drawn with the precipitation of phosphate in the surfaces of weathered glass. It is concluded that the amorphous phases produced on firing behave as chemically active substrates which facilitate the adsorption or precipitation of very fine grained calcium phosphate from the burial environment.     

基于信息权力论的智慧城市建设刍议

基于信息权力论视角,智慧城市的建设可以理解为面向信息权力争夺的城市竞争力提升战略。本文将信息权力分解为信息生产、信息获取和信息控制三个权力维度,并对其测算方法进行了讨论和定义;在此基础上,对我国现有23个"智慧城市"的信息权力进行了测度,并将之与城市竞争力评价结果进行了比较。分析结论显示,我国城市信息权力个体差异明显,尤其表现在信息生产和信息控制方面;城市信息权力和城市竞争力之间的多种组合类型,亦可为进一步的智慧城市建设因地制宜提供借鉴。根据分析结论,特别强调对于信息权力培育的重视,以及信息生产、信息获取和信息控制能力三者的协调发展。
