欧阳修的江淮情缘

从欧阳修描写江淮风物及优游之情的诗篇辞章、欧阳修与江淮名人的交游和历代江淮文人对欧阳修的品评三个方面,论述了一代文宗欧阳修与江淮大地及江淮文人结下的不解情缘。     

从旅游观念看明代文人士大夫的闲暇生活

自明代中期以后,对旅游的肯定已成一时之风,而旅游则已经成为文人士大夫闲暇生活的重要组成部分.文章通过对明代士大夫旅游观念系统的梳理,指出文人与道学家在旅游观念上具有很大的差异性.在此基础上,文章对士大夫的旅游体验又作了详细的分析,并对明代的游人进行了具体的细化,将其归为贵人之游、豪士之游、布衣之游与民众之游四类.     

基于系统仿真的高温行车空调器性能分析与实验研究

建立空调器部件和系统的仿真模型,将系统仿真技术应用到高温行车空调器的研制过程中,采用理论计算和实验验证相结合的方法研究产品的运行性能.通过数值求解,得到制冷系统循环的平衡点.通过模拟曲线和测试结果的对比分析,对仿真模型进行验证和完善.结果表明,高温行车空调器动态运行时,系统的各项参数均发生不同程度的波动,其中变化最显著的是制冷量和压缩机排气温度.在高温行车空调器系统设计过程中,应采取有效措施降低排气温度,以提高空调器整体性能.     

不同人群在艾滋病防治中面临的伦理问题及对策

从艾滋病(AIDS)患者、HIV感染者、高危人群和健康非感染者的角度探讨AIDS防治过程中存在的若干伦理问题,提出在AIDS患者和HIV感染者治疗中实行有条件地保密、药物研究中采用活动性对照试验;在禁毒和扫黄的前提下对高危人群发放安全套、推行针具交换政策和美沙酮替代疗法;对健康非感染者加大宣传力度、医务工作者应如何正确对待患者及做好职业防护等对策。     

用改进的人工鱼群算法求解TSP问题

针对人工鱼群算法在寻优过程中存在的不足,结合嗅觉在自然界鱼类捕食过程中的重要作用,在基本人工鱼群算法的基础上,提出了具有嗅觉特征的人工鱼群算法。最后,利用改进的人工鱼群算法成功解决了旅行商问题,并且通过比较基本人工鱼群算法与改进人工鱼群算法的实验结果,得出结论,改进后的人工鱼群算法在算法搜索时间、全局最优值精确度方面都有了显著的提高。     

Spatial and Temporal Aspects of Alcohol-Related Crime in a College Town

Objective: The authors aimed to clarify crime "movement" through the city of Madison to focus efforts to address consequences of student drinking. The authors examined all crime reported by police during the 2003 year. Methods: Using geographical information system (GIS) mapping and 2003 crime data from the University of Wisconsin-Madison and the city of Madison, the authors investigated the relationships among high-density alcohol outlets and various city neighborhoods. Results: Different categories of crime showed different temporal and spatial patterns: Serious crimes peaked between 2 and 3AM, coinciding with bar closing time. Less serious crimes peaked between 11PM and midnight. Reports of vandalism peaked in the morning and afternoon. "Hotspots" for different crimes moved throughout the downtown. Results were consistent with problems associated with high-risk student drinking in college communities. Conclusion: These results and maps generated by GIS led directly to changes made by city and university officials to address high-risk drinking.     

Views on Parent–Child Connectedness Among English- and Spanish-Speaking Parents of High-Risk Youth

This study highlights findings from focus groups on parent–child connectedness conducted with English- and Spanish-speaking parents of high-risk youth in the southern United States. The primary aim of the study was to extend research on parent–child connectedness, a broad protective factor for adolescent risk behavior. In addition to describing strategies and obstacles for enhancing closeness between parents and children, parents in Spanish-speaking focus groups also raised issues related to immigration, acculturation, and bicultural stress. Findings provide valuable insights for practitioners and policymakers seeking to improve parent–child connectedness and reduce adolescent risk behavior, with special insight about Mexican-origin, Spanish-speaking families.     

文化旅游资源与成都旅游的可持续发展

可持续发展已成为全球发展的永恒主题和战略目标。近年来人们开始强调人与自然的和谐共处,加强文化旅游资源的开发,实现旅游业的可持续发展。成都作为蜀文化中心和四川省会城市,历史文化沉淀厚重,文化旅游资源丰富。本文首先阐述了可持续发展和旅游可持续发展的内涵,以及文化旅游的涵义及其对旅游可持续发展的积极作用。还结合成都文化旅游资源的特点和优势,探讨如何实现成都文化旅游资源和自然资源的有效结合,实现成都旅游的可持续发展。     

衡阳市区域旅游形象定位探索

城市区域旅游形象是人们对某一特定城市各种信息在头脑中反映后而形成的综合认知印象。良好的城市形象对外可扩大旅游市场 ,对内可提高市民凝聚力 ,促进区域社会经济整体发展。根据衡阳市所具有的山水型风景城市、历史化文化名城、区域性政治经济文化中心优势 ,将其定位为我国南方最大的特色性文化旅游和宗教朝圣地 ,湖南省中东部地带重要的山地性生态休闲度假中心。     

岑参漫游河朔考

天宝三栽岑参漫游河朔。是年早春,岑参从洛阳附近的孟津渡河北上,过邯郸、贝州、冀州,于初夏季节到达此次漫游的目的地——定州安喜。夏末秋初,岑参从安喜南返,路过井陉而至滑州。在滑州,岑参得到了李白、高适、杜甫宋州相会的消息,但当他急忙赶到宋州的时候,他们已经散去。岑参在宋中稍作停留后到匡城,由匡城到临河,而后黎阳、新乡。第二年春天回到了长安。
