SOFT VERSUS HARD: AN AUSTRALIAN STUDY OF AN IDEOLOGICAL BASIS TO ATTITUDES TOWARDS ENERGY USE AND SUPPLY

A distinguishing factor of western societies is their consumption of energy. In 1986, Canada, the United States, and Australia had per capita consumption rates of 6.3, 4.7, and 3.2 times the global rate, respectively (DIESA 1988). Much of this energy is supplied by fossil fuels. At present, fossil fuels are economically attractive and their relatively high energy densities make them particularly attractive for transport purposes. However, their supply is finite (particularly in the case of petroleum) and their consumption produces atmospheric pollution. The depletion of fossil fuels or a rapid global warming of the atmosphere may eventually force changes in the way developed countries use energy (Lowe 1989). As everyone is an energy consumer, changes in consumption at a societal level are linked with changes at a personal level.     

PREHISTORIC RESIDENTS IN MARGINAL AREAS — AN EXAMPLE FROM WEST SWEDEN

Summary. The purpose of this article is to give an idea of the settlement history of a marginal area of the Swedish West coast. The presence of Stone Age man is evidenced by a great number of hitherto unknown, very small quartz quarries throughout the area. The Bronze and Iron Age settlements are evidenced by the ancient grave monuments. As the location at different altitudes of these graves cannot be explained by a lowering sea level, another explanation has to be sought. The area seems to have developed away from contact with the coastal zones and there is no evidence of settlement expansion.     

CHALLENGES IN APPROACHES TO SKELETAL STATURE ESTIMATION: AN EXAMPLE FROM PREHISTORIC EASTERN MISSISSIPPI AND WESTERN ALABAMA

Abstract

Although stature is used widely as a bioarchaeological health indicator, its determination and subsequent interpretation are not always straightforward. A study of 77 individuals from eight prehistoric populations from the Tennessee-Tombigbee Waterway illustrates this issue. Application of three common stature estimation formulae to five Middle/Late Woodland and four Mississippian groups strongly suggests that use of partial versus whole bone, choice of element, and stature estimation method can create disparate patterns in health interpretation, not only for the direction of differences but particularly regarding the degree of differences among groups.     

客源地—目的地关系质量对游客多分类旅游意愿的影响机制研究——以大陆赴台湾潜在客源市场为例

客源地—目的地关系和游客的旅游决策是旅游营销研究中的重要议题。本研究基于联想网络理论,构建了关系质量、多分类旅游意愿、游客风险倾向等变量之间的融合影响机制,以大陆赴台湾潜在客源市场为例,依托问卷调查数据,采用结构方程模型进行建模和检验。研究表明:(1)消极化的客源地—目的地关系质量通过直接效应和旅游形象的中介作用负向影响游客对目的地的旅游意愿(赴台旅游意愿);(2)消极化的关系质量负向影响游客的基础旅游意愿(出境旅游意愿),并强化了替代旅游意愿(非台湾旅游意愿)的替代作用;(3)低风险倾向游客的多分类旅游意愿受消极化关系质量的负向影响更强。本研究拓展了联想网络理论的应用领域,揭示了客源地—目的地关系质量对多分类意愿的影响机制。

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.     

FOREIGN DIRECT INVESTMENT FROM CANADA: AN OVERVIEW

Foreign direct investment (fdi) research on Canada has historically been centred on incoming rather than outgoing controlling capital. Yet the activities of Canada-based multinational enterprises (mne) have fostered an impressive outflow of direct investment abroad. To appreciate the importance of Canada's mne, one must understand the spatial and functional characteristics of Canadian parent companies and their foreign direct investments. To realize this goal, a sample of more than 17 000 examples of Canadian fdi (at various points in time) has been retrieved and analyzed. Spatially, the favourite target of Canadian outward fdi has been the United States and then the United Kingdom, but significant agglomerations of Canadian controlling capital can be found in many parts of the world (particularly in Western Europe, the Caribbean region, Australia, and Brazil, and in various Asian destinations). The locations of Canadian parent companies have been heavily biased toward the largest metropolitan cities. Additionally, multinational enterprises headquartered in Toronto and Montreal control (by far) the most foreign subsidiaries. In general, manufacturing, financial, and mining activities have constituted the most important endeavours of Canadian multinationals abroad. This pattern of functional emphasis, however, does vary with each specific location. Through a stepwise regression procedure, it was determined that market, trade (with Canada), labour, and crime conditions were critical place-specific criteria that affected the spatial decisions of Canadian direct investors. Par le passé, la recherche sur les investissements directs à I‘étranger (ide) du Canada a été axée sur les entrées de capital de contrôle plutôt que sur les sorties. Pourtant, les activés d'entreprises multinationales basées au Canada ont engendré“un flot impressionnant d'investissements directs à l’étranger. Pour appécier l'importance des entreprises multinationales du Canada, on doit comprendre les caractéristiques géographiques et fonctionnelles des compagnies mères canadiennes, et leurs investissements directs à l'étranger. Pour atteindre cet objectif, un échantillon de plus de 17 000 exemples de ide canadiens (à différents moments) a été choisi et analysé. Géographiquement, la cible favorite des ide canadiens vers l'extérieur a été les États-Unis, puis le Royaume-Uni, mais on retrouve d'importantes concentrations de capital de contrôle canadien en plusieurs autres parties du monde (surtout en Europe occidentale, dans la région des Caraïbes, en Australie, au Brésil etdans diverses destinations asiatiques). Pour le choix de la localisation de leurs sièges sociaux, les compagnies mères canadiennes ont nettement favorisé les plus grandes métropoles. De plus, ce sont les entreprises multinationales dont les sièges sociaux sont à Toronto et à Montréal qui gèrent la plupart (et de loin) des filiates étrangères. En général, les activités manufacturieres, financieres et minieres ont const'itue“la plus importante part des projets des multinationales canadiennes à l‘étranger. Cette tendance varie cependant selon les endroits. Par un modèle de régression, il a étéétabli que les conditions de marché, de commerce (avec le Canada), de travail et de criminalitéétaient des critères décisifs qui affectaient les choix géographiques des investisseurs canadiens.

VERTICAL INDUSTRY RELATIONS,SPILLOVERS, AND PRODUCTIVITY: EVIDENCE FROM CHILEAN PLANTS*

ABSTRACT We use disaggregated data on Chilean plants, and the Chilean input–output table to examine the impact of agglomeration spillovers on total factor productivity (TFP). In common with previous studies, we find evidence for intraindustry spillovers, but none for general cross‐industry spillovers. This picture changes when we take vertical industry relations into account. There are important productivity spillovers from plants in upstream industries. Interestingly, a similar effect cannot be found from plants in downstream industries. The number of plants in these sectors has no effect on plant‐level TFP, just as the number of plants in other industries that are neither important upstream suppliers nor downstream customers also has no effect.     

AN EPR AND ISOTOPIC STUDY OF THE MARBLES OF THE TRAJAN's ARCH AT ANCONA: AN EXAMPLE OF ALLEGED HYMETTIAN PROVENANCE*

The provenance of 20 marble samples drawn from the Trajan's arch at Ancona, which is supposed to be made of Greek, Hymettian marble, has been established on the basis of the independent use of EPR and isotopic data. The results of the two methods are in good agreement and unequivocally indicate a Proconnesian provenance. Sixteen samples are assigned to this site, whereas two are classified as untypical Proconnesian samples and the remaining two are assigned an unlikely Parian provenance. No indication exists for a possible Hymettian origin of the marbles. A multi‐method approach, which employs all of the experimental variables simultaneously, demonstrates that the 18 samples identified as Proconnesian belong to several different quarrying areas within the site. This result is taken as an indication that the Proconnesian quarries were run following a highly organized, semi‐industrial production model. The origin of the Hymettian/Proconnesian misunderstanding and the possible misclassification of other Roman monuments in Italy are briefly commented on.     

旅游者符号实践初探——以杭州西湖“西子”诗词为例

旅游者符号实践概念的提出旨在进一步凸显旅游者在旅游吸引物符号建构中的主体性。本文以杭州西湖的"西子"诗词为例,初步探讨了旅游者符号实践概念的基本内涵、理论支撑与研究价值。旅游者符号实践并不是对已有符号记忆的被动接受,而是借助旅游者的亲身体验,不断将其运用到旅游实践中去加以检验、深化和再创造的动态演进过程。符号学理论、实践理论和(身体)现象学理论构成了旅游者符号实践研究的三大理论支撑。符号实践是旅游者符号体验过程中主观与客观、过去与现在、已知与可能、我者与他者、代表物与对象等诸多二元关系的中间环节和关键枢纽,既关系到旅游者的符号体验质量,也与旅游目的地可持续发展息息相关,因而具有一定的研究价值。
