历史当事人的记述与历史真实——新见《剿共随军日记》释读

<剿共随军日记>是一本历史当事人的记述.它虽有强烈的"反共"宣传性,但也记录了国共两党、两军不少"历史真实",如"剿共"粤军与国民党"中央军"的矛盾关系、共产党和红军的组织与军纪优于国民党和"剿共"粤军、"剿共"各军的宣传工作不如红军、"剿共"粤军的募夫制弊端丛生,等等.对待历史当事人的记述,应依据其记述历史的立场、动机和方法,采取冷静、清醒、理性的科学分析态度.     

人工神经网络：一种新的旅游市场需求预测系统

20世纪上半叶中国“人文地理学”与“人生地理学”内涵演变研究

当今学界对于我国地理学发展史上“人文地理学”与“人生地理学”二者的内涵界定和关系阐述并不完全准确。通过对20世纪上半叶地理学科文献的解读,可以发现二者存在三个阶段的演化:第一阶段,为传统方志地学与近代人文地理学交汇下萌发,以分类呈现人文事象为主的“人文地理学”;第二阶段,为批判方志传统,主张以人地关系论为核心,并在法国学派思想影响下产生的“人生地理学”;第三阶段,为批判人地关系论,在景观论与辩证唯物主义理论相结合的背景下提出的“人文地理学”。在三个不同阶段,“Human Geography”一词未曾改变,但在中国代表的内涵迥异,相互之间存在部分的继承,但更多的是通过批判而形成的思想演化。其根源在于西方近代地理学思想传入中国后,与中国地方的学术环境及时代背景产生交融,继而形成内涵各异的学术思想变体。     

关于第二轮修志记述非公有制经济的思考

改革开放以来,随着非公有制经济在国民经济中的地位与作用日益重要,其内容载入志书已成必然。志书要记述好非公有制经济的内容,就必须对其内涵有相对准确的理解。在第二轮志书中根据狭义的非公有制经济概念,在特定的范围内,处理为以记述个体私营经济为主。在已出版的三级志书中,对非公有制经济的记述程度参差不齐。省级志书中,由于涉及的层次较高、地域范围较广,非公有制经济的资料较为丰富,故记述的内容也较充实。市级和县级志书中,有关非公有制经济的内容有所减少,差异亦较明显。非公有制经济的内容,宜采用在经济部类各篇章中相对集中的记述方式。     

Numerical simulation of mylonitization and structural controls on fluid flow and mineralization of the Hetai gold deposit,west Guangdong,China

The Hetai gold deposit (HGD) is a typical altered mylonite type gold mine in a ductile shear zone in western Guangdong, China. Geomechanical simulations of the HGD were carried out in this paper to examine the importance of the dilation‐driven fluid circulation in gold mineralization. The results show that three evenly‐spaced NNE shear zones of enhanced dilation are produced in the study area. The calculated principal compressive stress in the X direction in these zones ranges between ?420 and ?650 MPa, in line with estimates of ore‐forming pressure (fluid pressure). Ore forming fluid is focused into these features, as observed in the field. The calculated differential stress decreases from 275~350 to 148~225 MPa during the formation of mylonite zones. These, together with geological structural analysis and fluid pressure measurements, indicate that the mylonitization zone can provide a place of fluid focusing and a favorable environment for gold mineralization.

Cause analysis of meager salaries of Sichuan primary school teachers in the 1930s

This paper aims to investigate the phenomenon wherein primary school teachers in Sichuan received low salaries in the 1930s. Compared with other professions among either physical or nonphysical jobs, primary school teachers had lower salaries, which were often paid in arrears and deducted. The main causes were instability, mismanagement, and an unbalanced distribution of education funds. __________ Translated from the Journal of Sichuan Normal University (Social Science Edition), 2004: 2     

The Pickup Problem: Consumers' Locational Preferences in Flow Interception

This article addresses the pickup problem , wherein patrons briefly interrupt their predetermined journeys to obtain a simple good, such as fast food or a video, and then resume their journeys. This is a problem from the class known as the flow-interception location problems. Traditional flow-interception location models (FILMs) are used to select service locations such that the intercepted flows are maximized. In these traditional models, only flow quantities are considered; these models do not consider where a pickup is made in a journey. However, in the real world, consumers often wish to obtain a product or service at or near a specific location along their trips. The pickup model (PUP) proposed here considers consumers' locational preferences, providing a much broader, more realistic approach than FILM (a special case of PUP) to problems in the private and public sectors. By considering which patrons are served where, PUP transforms the FILM into a flow-interception location-allocation model, providing a fruitful garden for further research. Geographic information systems and optimization engines are integrated to investigate the PUP model in real-world transportation systems. Reported findings demonstrate that the optimal locations identified by traditional models arise solely from network flow structure, whereas the optimal locations identified by PUP result from trade-offs between network flow structure and the importance of proximity to preferred locations. One important discovery is that PUP solutions are superior to those of traditional FILMs if consumers have locational preferences. Up-to-date, real-world transportation networks provide a realistic test-bed for this and other models of the flow-interception type.
