旅游目的地忠诚度：一个历时态的概念模型

本文在对国外相关文献中旅游目的地忠诚度概念及其测量维度进行系统梳理的基础上,从目的地忠诚度形成的阶段性和动态性出发,构建了一个基于历时态视角的旅游目的地忠诚度概念模型。在厘清了态度、意向、行为和累积行为忠诚度的概念、形成过程及影响关系后,本文认为,旅游目的地忠诚度是一个由多个忠诚度维度构成的阶段性变量,在时间上呈现为一个周期性的连续演进过程。     

基于多层次灰色方法的旅游地产项目开发风险评价模型及实证研究

旅游地产是将旅游业和房地产两大产业融合而衍生出的一种新型地产开发模式,目前已经引起各地政府的高度重视,但在实际的开发与运行中存在着很大的风险性。因此本文对于旅游地产项目的开发风险从量化的角度进行分析评价,通过构建旅游地产项目开发风险的评价指标体系,以及采用主观的层次分析法与客观的变异系数法相结合的方法确定综合权重,以此建立起基于多层次灰色模型的旅游地产项目开发风险评价模型。并以A企业为例进行了实证研究,结果显示A企业的旅游地产项目开发风险处于一般风险与较低风险之间,适合进行项目的开发与投资。     

Trees as technology: planting shelterbelts on the Great Plains

The turbulent climate of the Great Plains made windbreaks necessary for the protection of settlers and their livestock and crops. At first individual farmers tried to plant their own shelterbelts but with little success. The US Forest Service, with the establishment of the Bessey tree nursery, in 1902, and the field planting of the Nebraska National Forest, developed the expertise to carry out farm forestry on the plains. In 1934 the Forest Service undertook the Prairie States Forestry Project, an eight‐year program to plant shelterbelts from Canada to Texas, in response to the Dust Bowl and the Great Depression. These shelterbelts were a technological solution to environmental and social problems. As they grew, successful shelterbelts developed forest characteristics and served as habitat for birds and wildlife. As systems that were both technical and ecological, shelterbelts embodied a confluence of culture and nature in the technology that farmers and foresters used to engineer a more suitable environment for American society on the Plains.     

Six seasons of wild pea harvest in Israel: bearing on Near Eastern plant domestication

Harvest experiments of wild crop relatives are essential for our understanding of the biology of wild plants embodied in the economy of ancient forager communities. Most of the previous experimental harvest reports spanned a single season and therefore are unable to address questions concerning long-term yield potential. Herein we report on six consecutive harvest seasons taking place at four sites in Israel that harbour wild pea populations: three typical Pisum fulvum sites and one typical Pisum elatius site. Three out of the four sites showed no indication of a decline in grain yield as a result of repeated harvest and the removal of a considerable portion of mature seeds. Site-specific factors seem to have a strong influence on the grain yield as no seasonal yield similarity was observed between adjacent and ecologically similar sites harbouring the same wild pea taxon. The erratic year-to-year wild pea yield we observed calls for a reassessment of the presumed role of grain legume species in Near Eastern hunter–gatherers' diet. Combined with published data on cultivation of wild pea, our results are inconsistent with models suggesting protracted domestication of Near Eastern grain legumes or with the preliminary attempts to apply Niche Construction Theory to the study of plant domestication in the Near East.     

Unpacking the discursive Irish woman immigrant in eighteenth- and nineteenth-century Newfoundland

From the late 1600s to the early 1800s, Irish migrants journeyed to Newfoundland to take advantage of opportunities in the lucrative Newfoundland cod fishery. Focusing on the eighteenth and nineteenth centuries, this essay explores constructions of Irish-Newfoundland womanhood as articulated by local British officials, the Catholic Church, and male-centred family history narratives. These discourses located women at the margins of early settlement experiences or rendered them invisible altogether. Yet Irish-Newfoundland women were able to negotiate their own subjectivities within this discursive terrain, finding spaces for identity construction in the disjuncture between rhetoric and lived experiences. Some resided more immediately under the hegemonic gaze and struggled to break free from dominant narratives. But most became essential workers in household fishing production outside the capital of St John's, and their vital contribution as shore crews gave them considerable power and authority both in their households and in the broader community. Performing demanding physical work on stages and flakes (elevated wooden structures) or in gardens and fields, carrying out various economic activities in their own right, they were hardly the unproductive, unruly bodies of British official discourse or the passive flowers of civilisation narrated from Catholic pulpits. And far from being absent from the migration story, they were central players in community formation and the economic life of the island. In this historical context, proximity to/distance from hegemonic knowledge production created variations in identity construction within a group often represented in the literature as homogeneous and powerless.     

Fragments of Boats from the Canale Anfora of Aquileia,Italy, and Comparison of Sewn‐Plank Ships in the Roman Era

Fragments of Roman sewn‐plank boats have been found, during rescue excavations, in the Canale Anfora, an artificial channel used by Roman ships to enter the Roman city of Aquileia. Remains were found in both 1988 and 2005 at the same site. Elements of what were probably two boats are analysed and compared to other finds of Roman sewn boats found along the coast of the Veneto and Friuli Venezia Giulia regions. They are evidence of the use of this technique, instead of the more widespread mortise‐and‐tenon system, in the quite limited area of the Northern Adriatic. These boats were used both for inland and for maritime navigation.     

Implementation of Sustainable Urban Drainage Systems to Preserve Cultural Heritage — Pilot Motte Montferland

The shallow subsurface in historic cities often contains extensive archaeological remains, also known as cultural deposits. Preservation conditions for naturally degradable archaeological remains are strongly dependent on the presence or absence of groundwater. One of the main goals at such heritage sites is to establish a stable hydrological environment. Green infrastructural solutions such as Sustainable Urban Drainage Systems (SUDS) can support preservation of cultural deposits. Several cases show that implementation of SUDS can be cost effective at preservation of cultural deposits. These include Motte of Montferland, City mound of Vlaardingen, Weiwerd in Delfzijl, and the Leidse Rijn area. In all cases, the amount of underground infrastructure is minimised to prevent damaging cultural layers. SUDS have been implemented to preserve cultural heritage. The first monitoring results and evaluation of the processes give valuable lessons learned, transnational knowledge exchange is an important element to bring the experiences across boundaries.     

The Holocaust in Italian Collective Memory: Il giorno della memoria , 27 January 2001

The article examines the first official, national Holocaust memorial day in Italy, the so-called Giorno della memoria (Day of memory), marked on the 56th anniversary of the liberation of Auschwitz on 27 January 2001. It looks at the ways in which the day acted as a filter for issues of national collective memory and identity, in particular state and public negotiation of the legacy of Fascism, as well as addressing broader issues of Holocaust remembrance. The article looks first at the origins of the Giorno della memoria in political and in legislative terms. Then it sketches in the events of the day itself, at national and local levels, in political, educational and cultural terms. This is followed by an analysis of media coverage and contemporary commentary, showing how various lines of interpretation addressed general issues related to the Holocaust and specifically Italian historical, ideological and contemporary questions.     

STRUCTURAL CONTROL ALGORITHMS IN EARTHQUAKE RESISTANT DESIGN

The dynamic finite element equations of a two-dimensional structure made of axial-flexural frame elements with tendon-driven actuators have been derived. A critical review of classical optimal control theory is made with respect to its application to the control of structure under seismic excitations. Seven control algorithms, including two newly proposed algorithms, have been described, investigated and discussed. The need of an optimal observer, Kalman filter, is discussed. The validity of separation theorem applicable to the optimal stochastic control of structure for earthquake resistance is shown. How the control system perform under the circumstances of actuator saturation is also shown. Several numerical examples are worked out to demonstrate and compare the efficiency and limitations of those control algorithms.
