Evaluations of diaries and GPS-enabled trackers to plot young peoples’ geographies – asking the participants what they think

Insights into the personal geographies of young people can be gained in many ways, but there is not always a focus on the effectiveness of the methodologies used, through a comparison of the different approaches, nor is there often an examination of how the participants in the study perceive the effectiveness of the research methods. Two methodologies are explored in this study: self-completion mobility diaries and the wearing of global positioning system-enabled tracking devices. The study focuses on the perceptions of the teenage school student respondents in the study (n?=?15) with relation to the user friendliness, the perceived accuracy, and the ease with which travel patterns can be recreated from the data. The participants were able to evaluate the two methodologies and to make judgements on the criteria provided. We argue that participants can contribute significantly to post-research methodological reflection.

An Enhanced Finite Element Macro-Model for the Realistic Simulation of Localized Cracks in Masonry Structures: A Large-Scale Application

ABSTRACT

Finite element macro-modeling approaches are widely used for the analysis of large-scale masonry structures. Despite their efficiency, they still face two important challenges: the realistic representation of damage and a reasonable independency of the numerical results to the used discretization. In this work, the classical smeared crack approach is enhanced with a crack-tracking algorithm, originating from the analysis of localized cracking in quasi-brittle materials. The proposed algorithm is for the first time applied to a large-scale wall exhibiting multiple shear and flexural cracking. Discussion covers structural aspects, as the response of the structure under different assumptions regarding the floor rigidity, but also numerical issues, commonly overlooked in the simulation of large structures, such the mesh-dependency of the numerical results.     

面向城市基调管控的建筑群色彩感知和意义理解分析——以北京故宫建筑群为例

北京新一轮总体规划提出保护城市色彩基调。本研究认为该任务的目的是保护色彩基调对于人的文化意义，因此从新文化地理学的角度提出问题，人们对城市色彩的感知和意义理解之间是否有联系?研究以北京故宫建筑群为研究区域，运用眼动实验调查人们对色彩的感知，以结构性访谈法了解人们的色彩意义理解，目的是探究文化在感知和认知中的作用，以及眼动实验方法在反映色彩意义理解结果的可行性。结果显示色彩感知与意义理解间两者无统计上的相关性，眼动指标无法解释被试对色彩意义的理解。研究结论是被试对色彩的理解具有“整体依赖”的特点，实践性建议是具有文化认同的城市色彩可以保留，同时允许主体对城市色彩有多角度的感知和积极理解。     

If you are not one of them you feel out of place: understanding divisions in a Northern Irish town

This paper examines and reflects on the use of Global Positioning System (GPS) tracking devices as a method to understand and analyse young people’s everyday movement in Northern Ireland, a divided society emerging from conflict. The paper also seeks to contribute to the extensive body of literature which already exists on young people’s geographies and movements within the Northern Ireland context. We highlight how the use of GPS together with more traditional methods gives us considerable insights of movements of young people in Northern Ireland and sheds light on the communal divisions in one town in Northern Ireland, Coleraine. We argue that the use of a GPS methodology significantly adds to the understanding of young people’s movements and geographies, particularly in a post-conflict context where notions of place and territory have particular significance.     

A method for finding stratified sites: Early Upper Palaeolithic sites in southern Moravia

There are several hundred recorded Early Upper Palaeolithic sites in Moravia, most of which are surface sites. The majority were exposed by agricultural plowing and subsequently discovered by pedestrian surveys whereas most of the stratified sites were found accidentally. Numerous unsystematic attempts in the past to find stratified remnants of sites disturbed by plowing have been unsuccessful. Here we present a methodology for locating stratified Early Upper Palaeolithic cultural contexts based on distribution of surface scatters. This involves pedestrian surveys guided by background research. All Palaeolithic artifacts were recorded using a handheld GPS with particular attention to calcium carbonate crust on artifact surfaces, which can be indicators of nearby stratified deposits. Exploratory test pits were then excavated followed by systematic excavations if the potential for stratified cultural deposits was deemed high.

Using this technique, we have discovered 11 new stratified Early Upper Palaeolithic sites.     

The use of tracking technologies in tourism research: the first decade

The past decade has witnessed dramatic growth in the implementation of various tracking technologies in tourism studies. A thorough review of literature reveals that 45 papers were published in peer-reviewed scientific journals, comprising 40 percent of the papers published in the three leading journals on tourism scholarship. The rate of papers published annually has grown in recent years and it is clear that this novel field is further expanding. The majority of studies analyzed employed GPS, mobile positioning, Bluetooth tracking, geocoded social media, and photo databases. The studies ranged in geographical scope from individual attractions to global capacity. Based on our review, tourism research that uses tracking data can be divided into three categories: the first generation of studies focused on methodological dimensions and the potential of tracking data. The second generation made use of spatially and temporally rich data and uncovered new aspects of tourism. The third generation made use of the new data sources to challenge fundamental questions on tourism and consumer behavior. Digital tracking data have clear advantages – data are spatially and temporally precise, geographic and temporal coverage of datasets is broad, and tracking data can be supplemented using questionnaires, sensors, and other sources.     

New approaches to the study of tourist experiences in time and space

Nowadays, a growing number of researchers are investigating subjective attitudes of people toward their environment with ever-increasing spatial and temporal resolutions. It seems that researchers' interest in daily experiences is not merely a passing research fad, but rather that individuals in current societies find more interest in their own momentary experiences. They talk about their affective states, they spend considerable portions of their income on intangible experiences, and they instantly share personal ‘moments’ through various online social media platforms. These trends are even more apparent in the tourism and leisure industries which aim to generate positive experiences among individuals. This research note points out new directions in the exploration of experiences during tourism and leisure activities. It discusses a new relevant concept, subjective momentary experiences on one hand and presents novel methodological opportunities on the other. In order to portray these new trends, a case study that describes the episodic experiences of festival attendants in a high tempo-spatial resolution is presented.     

贵阳市道路拥堵状态时空分布规律研究——基于出租车GPS大数据

利用贵阳市出租车GPS数据,建立ArcGIS空间模型计算路段平均行程速度,以空间数据库和ArcGIS空间分析为技术支撑,分析道路拥堵状态的时空演化规律。结果表明：①路网平均行程速度的时间分布特征具有高度相似性,且工作日与休息日分布差异大;②工作日高峰时段拥堵区域分布主要以老城区为主。休息日总体上呈现离散分布趋势,且晚高峰时段交通状况比早高峰更拥堵;③工作日早高峰交通拥堵路段呈由中心核心区逐渐向外围扩散的趋势,晚高峰呈由外围向中心核心区聚拢趋势。休息日早高峰不明显,晚高峰呈现由外围区域向内聚拢趋势。基于上述时空演化规律,从城市功能分散、城市道路网、城市空间发展、城市公交系统等方面讨论了贵阳市城市道路交通优化调整对策。     

Turquoise Mine and Artefact Correlation for Some Bronze Age Archaeological Sites in Hubei Province,China

In China, there are places that are rich in gem‐quality turquoise resources, including north‐west Hubei Province and the nearby Baihe County in Shaanxi Province, and many ancient mining sites, although the mining history remains a mystery. Based on the compositional data from reference samples of known deposits, a comparison of the major and trace element contents of archaeological turquoise may help with determination of artefact provenance. This paper discusses new evidence of provenance‐tracking of turquoise in this area, obtained from geochemical analyses using REE and other trace elements of 22 turquoises and their surrounding rock samples from six ancient mines and three archaeological sites. The results indicate that the three archaeological turquoises from the tomb of the Middle Spring and Autumn Period (580–560 bc ) and the Warring States Period (476–221 bc ) in Hubei Province were made of raw material from north‐west Hubei Province and the nearby Baihe County in Shaanxi Province. [Correction added on 29 October 2014, after first online publication: In the preceding sentence, the correct dates for the Middle Spring and Autumn Period, and the Warring States Period have been added]
