海峡西岸旅游产业在全国和亚太地区占有重要地位,旅游产业结构布局的调整有重大意义.当前海峡西岸旅游产业偏重观光游览,旅游投入偏少;偏重自然景观,旅游文化发掘不够;偏重旅行消费,旅游六要素不完备;偏重旅游旺季,时间上经营不平衡;偏重低级竞争,市场无序现象还比较严重.旅游产业布局存在旅游集散地与目的地错位、星散布局缺乏整合、重复布局分散客流、单体布局缺乏联系等问题.海峡西岸旅游产业结构布局调整应集中精力抓准重点,延长产业链,设计旅游精品,调整布局构建多级布局体系.  相似文献

ABSTRACT. Although researchers have deconstructed the myth of stark social differences between the various North American sub‐societies, an assimilating American melting pot and an ethnically oppressive monocultural Québec are still popular representations within Canadian majority discourses, such as the English‐language mainstream media and parts of academia. In this paper, I argue that images of ‘America’ and ‘Québec’ play important roles for the multicultural reconstruction of Canadian nationhood. Examining selected op‐ed articles from two Toronto‐based mainstream newspapers during the 1990s, I develop and exemplify a theoretical understanding of how national identities are constituted and transformed within inter‐ and intra‐national relations of power and alterity. I pay special attention to the particularisation of Canada through the confrontation with American nationhood, the ambiguities of recognising the distinctiveness of Québec inside Canada, and the consequences of projecting Québec's supposedly ‘ethnic’ nationalism outside the boundaries of Canadianness.  相似文献

Osteoarthritis is a major health concern in living populations, as well as being one of the most common pathological lesions identified in the archaeological record. The aetiology of the disease remains unclear, with a multi‐factorial influence of physical strain, age, genetics, and obesity. Previous studies have identified a relationship between the presence of knee osteoarthritis on the distal femoral joint and the morphology of the intercondylar notch, patellar groove, and medial condyle. The current study expands this research to investigate the relationship between distal femoral, distal humeral, and proximal ulnar joint morphology and osteoarthritis with 3D shape analysis techniques. These methods provide a more detailed analysis of joint morphology in order to determine any relationship between 3D shape and osteoarthritis. The results indicate a complex relationship between joint shape and knee osteoarthritis, with eburnated right femora showing a statistically significant association. The shapes associated with eburnated or affected femoral joints can be explained by osteophyte development, and therefore likely represent systematic shape changes and not a particular joint shape predisposing individuals to the condition. There was no identifiable relationship found in the proximal ulna or distal humerus, indicating that joint shape is unlikely to influence the development of the condition in the elbow joint and that any shape changes produced by osteoarthritis are not systematic or quantifiable. The joints analysed in this study were highly influenced by asymmetry, sexual dimorphism, and allometry, resulting in a small sample size of affected joints in many datasets. Further analyses of large skeletal samples are needed to more thoroughly investigate the possible relationship of distal femoral joint shape and osteoarthritis.

The skeletal remains of 18 individuals interred at the ancient Maya site of Caledonia (100 to 1000 C.E.), located in the Cayo District of Belize, w ere sampled for stable carbon and nitrogen isotope analysis in order to reconstruct their diet. Stable carbon and nitrogen isotope ratios in 18 bone collagen samples and stable carbon isotope ratios in bioapatite from 15 bone and 6 tooth enamel samples were assessed. Small sample sizes precluded the assessment of dietary variation with respect to age, sex, social status or time period among the Caledonia Maya. However, the sampled individuals consumed a varied diet consisting of maize, supplemented with some C3 plants, terrestrial herbivores and/or lower order freshwater resources such as snails and molluscs and possibly maize‐fed animals. This dietary variability with an emphasis on maize is unsurprising given the biological diversity surrounding the site and the known importance of this crop to the ancient Maya. As expected, the isotopic values from Caledonia are similar to those from nearby sites from similar time periods. However, four individuals exhibit a marine dietary signature, possibly indicating inland trade of marine resources from coastal sites, or the migration of coastal people to Caledonia. This study demonstrates the validity of sampling small, fragmented collections from minor Maya centres in order to gain valuable insight into ancient Maya dietary practices.

The number of studies using trace elements as indicators of diet has increased with time, but the majority have used few elements and a small sample. The present study has as a principal objective a multi-element analysis of diet in a large sample in which diagenetic changes have been shown to be unimportant. The analysis was made using concentrations of seven elements—Sr, Ba, Mg, Cu, Zn, V and Ca—in 197 individuals from the necropolis of ‘S' Illot des Porros’ (Majorca, Spain). The results show that these individuals would have had a mixed diet with a high meat component, principally of marine origin (molluscs and fish), but with an important consumption of seeds and cereals and a low proportion of vegetables.  相似文献

Examining recently excavated burnt burials, we explore the potential of spatial analysis to contribute to the understanding of changes that human body goes through during burning and relocation to the place of secondary deposition. Artificial heat decomposition of a body is a complex process that consists of several stages of intentional manipulation with the body. Each stage can be biased by several accidental factors which then significantly change the final archaeological record. We focussed on the post‐burning stage, especially the pathways of bone fragments to secondary deposition. We investigated spatial distribution and weight of bones in urns and pits and asked whether it is possible to observe their intentional arrangement. The trend of bone arrangement could be distinguished in most cases. Bones of peripheral parts of body were typically situated at the bottom; skull bones were usually concentrated in the upper part. However, the weight underrepresentation of all investigated burials was apparent. Deposition of selected burnt bones suggests their careful collection from the pyre and complex post‐mortem manipulation. Our detailed analysis aims to reconstruct particular steps executed during funeral rites of past populations. Copyright © 2016 John Wiley & Sons, Ltd.  相似文献

Using modern samples of known kin, this paper evaluates two fundamental aspects of kinship analysis in archaeological contexts: (1) choice of data (dental metrics or morphology) and (2) analytical approach (multivariate, distance‐based approach or a ‘rare trait’ analysis). Stone dental casts were analysed from 155 female individuals from four sampling locations in Kenya. Of these 155 individuals, only three pairs were close kin: mother–daughter, sister–sister, and first‐cousin–first‐cousin dyads. After variable winnowing, inter‐individual distances or similarities were calculated using 11 odontometric variables and 25 dental morphological variables. Resulting distance matrices were ordinated in two dimensions using multidimensional scaling. Odontometric data performed relatively well at identifying known relative pairs, but the results were heavily affected by choice of similarity measure (e.g. Euclidean distances vs. Gower coefficients) and pre‐analysis data treatments (e.g. raw data vs. principal components). Dental morphological data performed comparably with odontometric data but were slightly less effective. Rare traits were identified and compared among relative pairs for concordance, with mixed results. Rare morphological features were randomly distributed throughout the population and were not exclusively found in close kin. In combination, results indicated the sister–sister dyad was most consistently identified; however, in no analysis were relatives more phenotypically similar than all random pairs of unrelated individuals. A multivariate, distance‐based approach was more effective than rare traits at identifying relative pairs, but even under ideal circumstances, there is not enough variation present in the dentition to faithfully identify close relatives in the absence of contextual archaeological data.
