Lost,Exile and Return-An Analysis of Sheona’s Identity Reconstruction in“Sisters”from the Perspective of Spatial Theory

“Sisters”is the first novel in Irish-American author Colum McCann’s short story collection-Fishing the Sloe-Black River,which tells the story of Sheona’s search for her identity between Ireland and the United States.Colum McCann is skilled in writing about the spiritual dilemmas and identity search of ethnic minorities living in a foreign land.Employing the space theory and Sheona’s perspective,this paper examines her identity loss in Ireland’s patriarchal system,her migration to the US for identity pursuit,and her subsequent transnational journey between the two nations to reconstruct her identity amidst physical and mental trauma.

Analysis of Sophocles’s Antigone from the Perspective of Spatial Theory

In Foucault’s spacial theory,human body,as a unique space unit,is a space unit,and space is the basis of power operation.Therefore,the thesis takes the body as the carrier to explore the relationship between space and power.Space is also existential.Human being is a kind of spatial being,which just leads us to reveal the meaning of“being”.The trigger point of the tragedy of Antigone is whether the body of his brother Polyneices should be buried or not.The monarch,Creon,consolidated his throne by punishing the body of Polyneices in the most basic space and not allowing him to be buried.As a result,state-based power was resisted,and Antigone was opposed to Creon by strengthening family-based space.The conflict of power causes the tragedy of Antigone,and at the same time,it leads to the thinking of“being”.

Prediction method for risks of coal and gas outbursts based on spatial chaos theory using gas desorption index of drill cuttings

Based on the evolution of geological dynamics and spatial chaos theory, we proposed the advanced prediction an advanced prediction method of a gas desorption index of drill cuttings to predict coal and gas outbursts. We investigated and verified the prediction method by a spatial series data of a gas desorption index of drill cuttings obtained from the 113112 coal roadway at the Shitai Mine. Our experimental results show that the spatial distribution of the gas desorption index of drill cuttings has some chaotic charac- teristics, which implies that the risk of coal and gas outbursts can be predicted by spatial chaos theory. We also found that a proper amount of sample data needs to be chosen in order to ensure the accuracy and practical maneuverability of prediction. The relative prediction error is small when the prediction pace is chosen carefully. In our experiments, it turned out that the optimum number of sample points is 80 and the optimum prediction pace 30. The corresponding advanced prediction pace basically meets the requirements of engineering applications.

Material,energy and spatial fields for metallogenic prediction:Theory and practice An example:Limu Sn polymetallic crisis mines

The Limu tin deposits located in the Nanling tin and tungsten-polymetallic ore belt are now facing resource depletion after decades of exploitation.Peripheral mineral exploration therefore has become an urgent task.Using mineral exploration around the Limu crisis mines as an example,we introduce a breakthrough method of how the three-field theory,i.e.,the material,energy and spatial fields,is applied to intensively studies areas,a history of years of mineral exploitation and complex ore-forming systems.Taking a cue from Limu regional metallogeny,we based our investigation on the metallogenic information from geology,geophysics,geochemistry and remote sensing.We conducted our study of the three-field integrated information system,associated with metallogenic prognoses from deposits,with assignments and calculations which correct and allocate synthetic metallogenic prognosis by relying on GIS.We submitted a synthetic metallogenic prognosis map of tin in Limu where we delineated three ore target areas.A breakthrough was achieved by finding about 4785 t of tin metal outside the Shiziling deposit,which has been confirmed by drilling.The successful application in Limu shows that this three-field theory is of scientific and practical importance and deserves to be extended to utilization.

Heritage Communities in Consumer Contexts Spatial Production of Tourism Research-Take Qixian Zhao Yu Historical City as an Example

Taking Zhaoyu Historical City in Qixian County as an example,this paper explores the production process of tourism space in Zhaoyu Historical City in the context of consumption,based on Lefebvre's triadic dialectic theory.The study reveals that,driven by the development of tourism,subjects such as the government and planners possess absolute dominance over spatial representations,while residents demonstrate receptive and adaptive action strategies and social relations are reproduced,presenting a harmonious state.Further exploring the tourism community in the environmental performance of the subject of action,social relations,consumption demand,daily life practice,cultural capital,etc.,the daily life practice of the tourism community has transcended the original logic of tourism spatial production and has a certain extension.The mechanism analysis in this paper can help guide the healthy development of tourism space in the neighboring historical cities or communities and achieve the dual purpose of promoting the economic development of the community and heritage protection.

A theory on spatial correlation and vertical directivity of surface-generated ambient noise in the sea

A theoretical model of ambient sea noise including surface noise sources and stratified medium ocean is discussed. The noise sources are assumed to be statistically independent directional point sources distributed over the ocean surface, and the effects of ocean environment on ambient noise are studied. The normal-mode theory of surface-generated noise is developed, and the normal-mode formula of the directional density function suitable for small grazing angles is analytically continued for being suitable for great grazing angles and consistent with the ray formula. The unified formulae for calculating the intensities, spatial correlation and vertical directivity of ambient sea noise are presented.

Risk Assessment of Heavy Metal Pollution in Sediments of the Fenghe River by the Fuzzy Synthetic Evaluation Model and Multivariate Statistical Methods

Concentrations of heavy metals in 74 sediment samples from the Fenghe River, which originates from the north of the Qinling Mountains and flows through Xi'an, Shaanxi Province, China, were characterized by employing geographic information system(GIS)mapping, fuzzy synthetic assessment, and multivariate statistical analysis to determine the enrichment characteristics of heavy metals as well as their potential risks of pollution to sediments. Al, Cd, and Co were the major pollutants, with a high enrichment factor(EF) value. Heavy metal concentrations from samples near the paper plant were maintained at a high level. Significant enrichment of Al, Ba, Cr, Ni, Pb, and Co was found in the midstream and downstream, while high concentration of Cu occurred in the headwater stream. Based on the cluster and principal component analyses, sediment metals mainly came from the paper plants, agronomic practices, natural sources, and tourism, with a contribution of 51.59%, 23.01%, 14.21%, and 9.88%, respectively. Sediment pollution assessment explored using fuzzy theory based on the entropy method and toxicity coefficient showed that 26, 32, and 11 sites fell into Class III(slightly polluted), Class IV(moderately polluted), and Class V(heavily polluted), respectively, and their scores of membership degree in the polluted level were on the rise, suggesting a relatively high degree of sediment metal pollution in the study area. Closely related to the excessive industrial and agricultural applications, metal pollution in sediment is necessary to be addressed in the Fenghe River.

Space Gene

Based on typo-morphological studies,this paper proposes the concept of “space gene” from the perspective of urban spatial development theory.Specifically,space gene refers to a unique and relatively stable pattern of spatial organization formed as a result of long-term interaction among the three dimensions:urban space,natural environment,and socio-culture.It conveys distinctive characteristics of different regions and contributes to a unique city identity and a harmonious relationship among the three dimensions.This paper points out that urban planning and design can be localized through the identification-analysis-guidance process of space genes,avoiding both the design scheme that does not respect culture and nature and the practice that a unified model is adopted to create same images in different cities,as well as prompting the directional turn of urban planning and design approaches from space form creation to space gene analysis.It provides an effective design path for a win-win result among urban development,natural protection,and cultural inheritance.Furthermore,the paper discusses the prospect of the Space GenBank Project.
