Community Perspectives Toward a Marine Reserve: A Case Study of San Felipe,Yucatán,México

San Felipe marine reserve, in Yucatán, México, is unique, and particularly suited for a case study because the local community created it without a mandate from higher levels of government. This article presents the results of a survey of local interest groups using the method of paired comparisons and rank correlation analysis, to reveal local judgments about the severity of damages to coastal habitats and the level of impacts of activities that cause the damages. The results show that fishers differ significantly from other interest groups in their rankings of the severity of damages to habitats and of impacting activities. These findings suggest that despite the overlapping interests in protecting the resources and the critical habitats, the different perspectives of local interest groups about the severity of damages must be considered in the management of San Felipe marine reserve.     

关于公交线路线形及对位编码的思考

把城市公交线路站点进行线性回归,将其归纳为纵线、横线、左斜线、右斜线和环(含弧)线,并对社区公交提出新的见解.同时采用了分线形按方位区间分别对位编码的方法,对普通的公交线路番号的每个代码赋予特定的含义,使其具有明确的线路走向和方位识别功能.还对“线形布线及对位编码法”在实施中可能出现的问题及应对措施提出了自己的意见.该...

A ‘placeful’ station? The community role in place making and improving hedonic value at local railway stations

In recent years, railway stations have come to be seen as non-places within society, points of transit and nothing more. The role of the station in place making is disputed with stations seen as both creating and destroying a sense of place within a community. Our study is located within the railway stations of Scotland and explores how local communities have been empowered to reclaim, customise, and re-appropriate stations to simultaneously create a sense of place and better promote their community to the outside world. Drawing on ethnographic research we refute the notion that stations are somehow ‘placeless’. We show how through a process of legitimisation, a sense of ownership and appropriation of the station environment, communities are able to transform the station, improving hedonic value and recapturing a sense of place.

APON技术在CATV系统中的应用

CATV系统为旅客及车站办公人员提供综合视频信号。随着数字电视的普及,越来越多的既有站房、行车公寓进行了数字信号传输模式改造。现有的改造方式利用了既有的区域网电视信号传输通道,未对传输方式进行变革,不能满足数字电视更大的数据流量。一种将ATM技术和PON模式结合的APON技术满足数字电视的传输需求,且传输距离长,适用于新建大型站房。     

The place of transport in facilitating social inclusion via the mediating influence of social capital

Social policy makers rarely associate the ability to be mobile with having a role in the facilitation of social inclusion. This paper provides an initial exploration of the association between a person’s travel patterns and their risk of social exclusion. Information is drawn from a major Australian Research Council transport study which interviewed 535 people from Metropolitan Melbourne, Australia. It includes an analysis of the extent of the person’s bonding and bridging social networks, their connectedness to the community, self-assessed level of well-being and their beliefs about whether or not they are able to control outcomes in their life. It was found that those who had the greatest risk of social exclusion, travelled less often and less distance, owned fewer cars and used public transport less, than those who were more socially included. However, those who were more at risk of social exclusion did not identify their lower trips as due to either a lack of transport, or problems with the public transport system. The ability to have good bridging networks appears to be related to increased trip-making and promotion of social inclusion but not necessarily self-assessed well-being which is satisfied by bonding networks.     

Optimal timetable development for community shuttle network with metro stations

This paper investigates an issue for optimizing synchronized timetable for community shuttles linked with metro service. Considering a passenger arrival distribution, the problem is formulated to optimize timetables for multiple community shuttle routes, with the objective of minimizing passenger’s schedule delay cost and transfer cost. Two constraints, i.e., vehicle capacity and fleet size, are modeled in this paper. The first constraint is treated as soft, and the latter one is handled by a proposed timetable generating method. Two algorithms are employed to solve the problem, i.e., a genetic algorithm (GA) and a Frank–Wolfe algorithm combined with a heuristic algorithm of shifting departure times (FW-SDT). FW-SDT is an algorithm specially designed for this problem. The simulated and real-life examples confirm the feasibility of the two algorithms, and demonstrate that FW-SDT outperforms GA in both accuracy and effectiveness.     

Identification of communities in urban mobility networks using multi-layer graphs of network traffic

This paper proposes a novel approach to identify the pockets of activity or the community structure in a city network using multi-layer graphs that represent the movement of disparate entities (i.e. private cars, buses and passengers) in the network. First, we process the trip data corresponding to each entity through a Voronoi segmentation procedure which provides a natural null model to compare multiple layers in a real world network. Second, given nodes that represent Voronoi cells and link weights that define the strength of connection between them, we apply a community detection algorithm and partition the network into smaller areas independently at each layer. The partitioning algorithm returns geographically well connected regions in all layers and reveal significant characteristics underlying the spatial structure of our city. Third, we test an algorithm that reveals the unified community structure of multi-layer networks, which are combinations of single-layer networks coupled through links between each node in one network layer to itself in other layers. This approach allows us to directly compare the resulting communities in multiple layers where connection types are categorically different.
