现代旅游信息管理系统(TIMS)的构建   总被引:6,自引:1,他引:6  
旅游信息管理系统的开发与应用是推动当前旅游业发展的一重要因素。本文根据目前我国众多已投入使用的旅游信息管理系统的现状,就该类系统的功能改进、数据库重新设计及系统建设和运行机制等问题,提出了自己的一些新看法。在具备传统的基本功能基础上,现代旅游信息管理系统要加强为企业经营决策、区域旅游开发决策服务的功能;旅游信息数据库的设计也要以这一功能的实现为目标做出相应调整;在系统的建设过程中要坚持政府统筹管理、景区自主开发的原则。  相似文献

The city dashboard has become an integral component of smart city asset management systems. It leverages data collected from multiple sources to monitor performance and enable evidence-based decision making. This article investigates the use of a design thinking framework to develop a functional and easy to understand city dashboard. The Smart Social Spaces project is used as a case study to illustrate how design thinking can be employed to develop an asset management dashboard, enabling efficient management of public space and infrastructure. The article profiles the unique collaboration between a local government, a multi-disciplinary team of university academics, and a street furniture designer and manufacturer, all located in Sydney, Australia. We unpack some of the design practice nuances that led this project to receive national awards and international recognition, and most importantly, created a user-friendly system to track and maintain public micro assets. We conclude with lessons learnt and recommendations for dashboard development through a design thinking process.  相似文献

An analysis of Goethe's Farbenlehre (Theory of Colours), and of its significance for the development of geological mapping, requires an interdisciplinary approach and specific knowledge of both the history of cartography and the science of chromatics. Thus far there has been little research in either of these areas by historians of geological cartography or by students of Goethe's Farbenlehre. In particular, the influence of Goethe's Theory of Colours on early geological map colouring has not yet been explored, and the present article is an attempt to rectify that omission. After an introduction to the emergence of geological maps during the Age of Enlightenment, the discussion focuses on Goethe's substantial contribution to the selection of colours for Christian Keferstein's General Charte von Teutschland (1821). Detailed study of the available textual and cartographical source material reveals that Goethe applied the principles of his Farbenlehre as a basis for the colour chart that Keferstein used to delineate the rock formations shown on his map. The article concludes with a brief consideration of the extent to which the joint Goethe–Keferstein venture influenced the future of geological map design.  相似文献

Ground-borne vibrations induced by mine blasting are typically of low amplitudes, which are not considered a major concern for modern engineered structures. However, historic structures are often considered more vulnerable due to inadequate knowledge regarding the state of construction materials and structural response. Specifically, the construction materials used might be fragile or have deteriorated to a stage that could be vulnerable to such vibrations. Simplistic rule based on peak ground motion parameter has been adopted worldwide for safety assessment, while the frequency characteristics of vibrations are not taken into account. Further, there is very limited study on response of heritage structures to near-field blasting. This article presents a practical structural vulnerability assessment method for mine blast-induced vibrations. In particular, a design response spectrum model is proposed based on close range measurements of nearby mine blasting, which is compared with an existing design spectrum model for far-field mine blasts and a typical design spectrum model for earthquake actions. The method is illustrated through a case study of heritage masonry buildings in Australia. The unique blast data presented and the generalized methodology would be useful to both structural engineers and blast engineers in considering potential effects of blasting on heritage structures.  相似文献

The use of renewable hydraulic energy sources by mankind most likely has its origins in the development of the watermills. To understand the functioning of these mills, this article first reviews, through the analysis of different bibliographical sources, the technical evolution of the machinery used since the appearance of the first watermills to grind cereal grain in the 1st century bc.

Secondly, a particular area of the south-west of Spain, Alcalá de Guadaíra, has been selected for study, whose strategic location as well as its hydrological characteristics gave rise, firstly, to an intensive milling industry, and, later, a famed baking industry, from the late Middle Ages until recent decades. The huge development of these two industrial activities has made Alcalá de Guadaíra an exceptional example in Spain, with 40 watermills in the early 18th century.

Extensive work on site allowed the analysis of the state and types of watermills that still exist in this area, identifying their similarities and differences. Unfortunately, after they fell into disuse, only 28 of these mills remain today; 12 of them are in a relative good state of preservation, seven in an alarming state of ruin and, of the other nine, only some unrecognisable vestiges remain. Some of these mill buildings have been restored recently, although their machinery is missing. Only from old photographs or by visiting mills restored in other areas is it possible to determine how these watermills worked.

Due to the lack of financial resources to carry out physical restoration of the industrial heritage missing in these flour mills, a virtual model of one of them has been developed. This work provides, at least virtually, a reconstruction of the traditional mills which helps promote technological studies and shows how they worked, as part of virtual exhibitions. In addition, a computer application of augmented reality has been developed that any visitor can install on a mobile device to display the virtual reality of the machinery, generated by 3D models, so they can visualise the physical reality that they would have found in the mill.  相似文献

In juvenile dependency law and the spaces in which it is practiced, race, class, and gender power are produced together. This article examines the design of monitored visitation rooms in a Children’s Court in Los Angeles and argues that the esthetics of domesticity in the courthouse and the body of law practiced inside are built upon and reify a model of white, hetero-patriarchal family that precludes black filiation, both materially and metaphorically. Ultimately, this research provides a framework to understand the relationship between political power and cultural space, between normative domesticity and the punitive structures of law, and between ideologies of whiteness and the devastating experiences of black and nonwhite families in the dependency system.  相似文献

Little research examines the stage of the policy process during which policy alternatives are formulated. Using quantitative and qualitative data from Swedish local politics, we address this deficiency by analyzing the process by which the number of specific policy alternatives is reduced. The findings suggest that, in approximately 20 percent of issues, more than one alternative will reach all politicians making the binding decisions. Most local politicians, in both the majority and opposition factions, think that they lack sufficient information on alternative policy designs. We also find a “political bias,” that is, alternatives are discarded at an early stage because they are deemed not politically feasible. Politicians outside the inner circles, especially those with higher education, would like to see more policy alternatives to discuss and from which they can make choices.  相似文献

Causal process tracing (CPT) has emerged as an important method of causal inference in qualitative social science research, most notably in case study research designs. There is now a considerable literature on the aims, philosophical groundings, and methods of process tracing. This paper reviews the CPT literature to assess what new directions it may suggest for policy studies. The first part of the paper sets out the methodological advantages CPT offers in building and testing theories of policy change, most notably in supporting a theoretical pluralism to address the problem of complexity in policy studies. Building on recent scholarship across the social sciences, the second part examines step by step the recently minted “best practice” for undertaking CPT in policy studies. This part includes discussion of the possible pitfalls of CPT as a method; common errors involved in its use are set out and minimization strategies offered. In particular, while acknowledging the usefulness of Bayesian tests for causality as heuristic devices, we emphasize the limitations of applying such tests in practice. Possible correctives are suggested. The final part of the paper speculates more generally on the potential of CPT to improve our investigation of patterns of policy change over time.  相似文献

A previous article investigated the methods used to design the 9th-century vessel from Bozburun, Turkey, and a basic methodology emerged which combined Richard Steffy's emphasis on the comprehensive deconstruction of a hull with the segregation of hull-construction into the phases of conception, design and assembly. This article tests this methodology by applying it to the 11th-century craft from Serçe Limanı, a vessel studied and reconstructed by Steffy. It discusses the resulting design-method, the similarities between this method and that used on the Bozburun vessel, and how we gain insight into changes in the maritime community which built these ships.

新公共管理是20世纪70年代以后西方各国先后开展的以“企业家政府”为理论模型、以市场化运作模式和私营部门的管理为研究方法、以提高政府工作效率为目的的一项改革运动。新公共管理对政府流程再造的初期的确发挥了一定的作用,提高了行政效率,但是仍然无法改变官僚制的人事制度。新公共管理所提出的私营部门的管理方法,只是对官僚制的修正与补充,是对官僚制的扬弃,而不是摒弃。  相似文献
