乡村社区旅游生计代际传承的过程及影响因素——以栾川县重渡村为例

在乡村振兴背景下,旅游生计成为乡村可持续发展的重要议题,但与之相关的研究较为匮乏。文章以栾川县重渡村为案例地,通过对亲代和子代进行半结构化访谈,探讨旅游生计代际传承的过程及其主要影响因素。研究发现：(1)旅游生计的代际传承经历了亲代生计开拓、子代培养和发展、共同经营、生计传承四个阶段,并与重渡村这一乡村旅游目的地起步、培育、快速发展、规范管理的生命周期相适应。(2)文化因素、主体因素和规制压力是影响生计传承的主要原因。(3)旅游生计的代际传承关乎乡村旅游的可持续发展和乡村振兴战略的有效实施,相关问题值得进一步探索和研究。     

DEM Algorithm for Progressive Collapse Simulation of Single-Layer Reticulated Domes under Multi-Support Excitation

In this paper, the Member Discrete Element Method (MDEM) is modified and perfected for three aspects: the algorithm itself, loading and computational efficiency, and to accurately and quantitatively simulate the progressive collapse for large-span spatial steel structures. In addition, the corresponding computational programs are compiled. First, from the perspective of the method, a meshing principle for discrete element models is determined, a treatment for material nonlinearity and strain rate effect is proposed, and a damping model is established. Next, the Displacement Method is introduced to determine the multi-support excitation for the MDEM, and then motion equations of particles under multi-support excitation are derived. On this basis, the specific process of gravitational field loading is presented. Furthermore, parallel implementation strategies for the MDEM based on OpenMP are constructed. Finally, the collapse simulation of a 1/3.5-scaled single-layer reticulated dome shaking table test model under multi-support excitation is carried out. The comparison demonstrates that the ultimate load and failure mode as well as the complete collapse time of the numerical results are consistent with the experimentally measured responses, and the configuration variations from member buckling and local depression until collapse failure are fully captured. Moreover, the displacement time-history curves obtained using MDEM are almost identical to the experimental measurements, and there is a nuance only in the amplitude. It is verified that MDEM is capable of precisely addressing the collapse failure for large-span spatial steel structures. Additionally, the failure mechanism for structures of this type is naturally revealed.     

An assessment of the technology level and knowledge intensity of regions in Turkey

The paper investigates the patterns of technology and knowledge of the regions. The first aim of the paper is to determine cluster templates at the national level. The second aim of the paper is to investigate the technology and knowledge composition of the regional highpoint clusters. The paper identifies patterns of industrial linkages to define cluster templates and regional highpoints. The second part uncovers regional distributions of technology and knowledge. The data comes from Turkey’s 2012 input–output table. The location quotients use industrial employment statistics from the Turkish Statistical Institute. The technological and knowledge intensity classification follows Eurostat. The findings reveal 10 cluster templates in Turkey. Spatial distribution of the highpoint clusters reveals that most regions contain highpoint clusters with low technology and low knowledge-intensive sectors. The results reveal that highpoint clusters in Turkey’s regions contain industries whose technologies do not demand high skills, knowledge and sophistication. Limited existence of high-tech industries and low knowledge intensity in Turkey’s industry composition is a limiting factor for transition to high value-added manufacturing. Special emphasis should be directed towards constructing regional advantage, given the current levels of technology and knowledge intensity.

略论抗日战争时期的澳门

澳门的命运始终与祖国休戚相关,抗日战争时期澳门虽未被日军占领,但也同样历经了日本掠夺的苦难,同时在抗战中起到了积极的作用。澳门战略地位之重要与香港一样,世人皆知。它是中国通往世界的南大门,也是东西方各国和东南亚各国的交通要道。由于澳门一直未被日军占领,它在中国的抗日战争期间曾发挥过积极和有力的作用。第一,澳门民众积极声援和直接参加抗击日本侵略者的斗争。早在“九一八”事变后,澳门同胞就以“救灾”的名义投入神圣的抗日救国运动。后来在抗日战场上血洒长空的林耀等即是在此时返回内地,进入航空学校的。澳门同…     

Changes in Land-Use Preferences of Small-, Medium- and Large-Scale Industries Located in Metropolitan Areas (Case Study in Istanbul)

In metropolitan areas, the changing spatial land-use preferences of the industrial sector are the most important determinants in the forming of the macro-form. Metropolitan areas, especially in developing European and Asian countries, become troubled cities with agglomerations of population and investment as a result of failures to apply satisfactory macro-policies and plans throughout the country. Industrial investments on various scales and the land-use preferences of investors have changed over time. The land preferences of production and headquarters of the manufacturing sectors have become basic determinants in the formation of settlement systems due to the transformations that occur alongside technological, economic and social development. This article examines whether or not the basic land-use criterion of the manufacturing sector changes in small-, medium- and large-scale businesses according to their labour structure, defined through an examination of the sectoral structure and relations of scale. Taking the increasing rate of the Gross National Product of the industrial sector in metropolitan areas in every country into account, and examining the land-use preferences of various industrial sub-sectors and scales will serve as an important input when making new planning decisions. The industrial land-use criterion will be effective in the transformation, reorganization or directing of new focuses for the agglomerated industrial structure, especially in Istanbul, which features both Asian and European metropolitan area characteristics. This article will define the existing industrial structure of the Istanbul metropolitan area; and differences between the various scales of land-use preferences within industrial investments will be presented, based on the findings of two investigations carried out over a 5-year period. Several important criteria for industrial investors seeking to establish themselves in metropolitan areas will be determined in the article.     

中日建筑民俗比较研究

日本的建筑,包括城池、庙宇和民居,都深受中国的影响,京都、奈良就是按古长安的模式建造的,连平城京宫的12道门,均取长安城门之名命之;特别是建筑风俗的理念,基本上是中国风水理论的演绎,五行四象布局被普遍认同。日本明治维新以后,由于工业社会的影响和西方文化的冲击,人们在接受中国传统思想的同时,又企图以现代科学的方法加以实证,使这些传统变得更加理性和严谨。而中国的建筑民俗,一方面由于统治思想的打压,被视为“封建迷信”,潜流于乡间和底层社会;另一方面主流社会为适应政治经济和观光旅游的需要,变换形式加以炒作,使其功利目的更为彰显,双方都在按各自的套路发展。     

封开，岭南文化的发祥地

本想在封开只做短暂的停留,看看杨池古村就走,到了封开,竟就由不得想赖在那儿。 一个偏远山区的小城,文化根底异乎寻常的厚,岭南文化的发祥地,陆、海丝绸之路的连接点,“北 风”、“海浪”会冲地,北回归线上奇异的国家地质公园,哪一项都让人牵肠挂肚。在张九龄开通梅岭 古道以前,这里因水路交通的便捷在唐以前兴蛊了一千多年。     

Not Only Helpless but also Hopeless: Changing Dynamics of Urban Poverty in Turkey,the Case of Sultanbeyli,Istanbul

This paper is an attempt to understand the changing characteristics of urban poverty in Turkey since 1980. First, it analyses how the urban poor in Turkey had adopted aggressive survival strategies by strengthening their solidarity networks on religious, ethnic and cultural bases until the 2000s. Then it sheds light on how those networks have dissolved later on thanks to a set of internal and external factors and concludes that Turkey now faces deepening poverty levels and engendering new forms and dynamics of poverty. This paper is based on the Sultanbeyli district of Istanbul, a district almost entirely composed of unauthorized houses whose population grew at an unprecedented rate after 1980; and it is a perfect case for the study of issues relating to migration, urbanization and poverty in Turkish cities.
