On the Constituent Attributes of Software and Organizational Resilience

Abstract

The conjecture is put forward that a better understanding of resilience may be reached by decomposing it into a number of ancillary constituent properties, in the same way as a better insight into system dependability was obtained by breaking it down into safety, availability, reliability, and other sub-properties. Three of the main sub-properties of resilience proposed here refer respectively to the ability to perceive environmental changes; to understand the implications introduced by those changes; and to plan and enact adjustments intended to improve the system–environment fit. A fourth property characterizes the way the above abilities manifest themselves in computer systems. The four properties are then analyzed in three families of case studies, each consisting of three software systems that embed different resilience methods. Our major conclusion is that reasoning in terms of our resilience sub-properties may help reveal the characteristics and, in particular, the limitations of classic methods and tools meant to achieve system and organizational resilience. It is suggested that this method may be a prelude to meta-resilient systems, which are able to adjust optimally their own resilience with respect to changing environmental conditions.

Resident perceptions toward tourism impacts in historic center of Yazd,Iran

ABSTRACT

Although demographic changes as a result of the departure of former residents have caused the historical center of Yazd to lose its residential character, the area has recently taken on another role with the significant increase in the number of foreign tourists and the emergence of traditional hotels, restaurants, and café shops in its historical center. This newly emerging phenomenon has modified the nature of this part of the city, converting it into a rather touristic area, particularly in the Fahadan neighborhood. An examination of the perceptions of residents reveals that those in the Fahadan neighborhood in Yazd have a generally positive attitude toward tourism development. In addition, the interviewees pointed out three major impacts from the increase in tourism: (1) improvement in the physical and environmental quality of the old urban area due to the initiatives taken by the government and the private sector; (2) positive social and cultural changes in residents because of communication with foreign tourists; and (3) increasing community awareness and pride toward its cultural and national heritage. Nowadays, the people of Yazd increasingly welcome the arrival of foreign tourists, have laid the foundations for their arrival, and even received them warmly in their religious rituals. However, our observations indicate that the increase in touristic activities in the historical areas of Yazd (especially in the Fahadan neighborhood), as well as weakening the residential role, pose the risk of the museumification of this area. Furthermore, the restoration of old spaces and monuments for the sole purpose of attracting tourists causes the commodification of heritage, resulting in a potential loss of authenticity.     

邻里环境感知对中国城市居民自评健康影响研究——以武汉市为例

邻里作为城市居民的重要日常生活场所，对健康的影响引起广泛关注。本文选取武汉市南湖街道这一典型住区，运用多元回归分析，针对商品房和保障房邻里展开对比研究，解析不同类型邻里中居民的邻里环境感知对自评健康的影响差异。研究发现，控制个人因素后，体育休闲设施感知、归属感和安全感显示出对自评健康独立且显著的影响。而在对比研究中，商品房邻里的居民自评健康受邻里环境感知的影响较显著，而保障房邻里的居民自评健康受个体层面特征的影响较显著。因此，宜针对不同类型邻里制定差异化的社区健康提升策略。     

社区居民参与城市会展业发展的社会交换关系研究——以广州琶洲村村民为例

广州的琶洲地区是广州会展业的代表符号,琶洲村是会展业促进城市化发展的典型城中村。本文以琶洲村村民为例,从社区居民的经济影响感知视角解析会展业发展过程中居民的社会交换关系。研究显示:①城市会展业成为社区重要的社会交换关系变量,社区经济对会展业的依赖性增强。②在会展业发展过程中,外来者的进入打破了原来社区交换关系的均衡与稳定,社区参与交换关系的网络呈多元化特征;社区居民之间的内部交换关系发生了变化,正经历竞争与分化的阶段。③社区居民不满足现有的外部交换关系,表现出对更高层次交换关系的热切期盼。     

展览会主题定位与终端客户效益感知——以东莞两个典型展览会定性分析为例

本文运用定性研究的方法,对在中国广东东莞举办的两个不同主题定位的（即比较宽泛的及比较细化的）展览会的终端客户效益感知进行比较,试图探究展览会专业化主题定位的必要性。研究表明终端客户对主题细化的展览会的效益感知明显高于主题宽泛的展览会。因为主题细化的专业型展览会主题明确,有特定细分的参展商和专业观众。提升了终端客户相互的满意度。而主题宽泛的展览会缺乏明确的目标观众,也缺乏可供比较和信息交流的同类参展商,终端客户参展效益较低。     

Community Antagonism Towards Asylum Seekers in Port Augusta,South Australia

An overtly hostile response to asylum seekers was observed in questionnaire responses provided by residents of Port Augusta, South Australia in April 2002. A social construction approach to identity and representation was used to interrogate this antagonism within its social, cultural, political and geographical contexts. Asylum seekers were constructed as ‘burdensome’, ‘threatening’ and ‘illegal’, and opposition to them was set within the discursive framework of a ‘Self/Other’ binary. Enmity towards asylum seekers was articulated concurrently with overwhelming support for the Federal Government's exclusive and deterrence‐oriented asylum policies. However, vehement opposition was expressed regarding the government's decision to construct Baxter Immigration Reception and Processing Centre in close proximity to Port Augusta. Factors contributing to the respondents’ negative perceptions of asylum seekers include xenophobia (specifically Islamophobia), events of geopolitical significance, and problematic government and media representations of asylum seekers. An awareness of these factors is necessary to unpack and, potentially, to destabilise the negative constructions of asylum seekers circulating in contemporary Australian discourses. Their entrenchment in the national consciousness may lead to tangible social implications including fear, friction and ultimately violence between the ‘Self’ and ‘Other’, and this should therefore be countered. Community antagonism also contradicts notions of a culturally tolerant Australia and fosters electoral support for the policies of exclusion and deterrence that undermine Australia's commitment to international human rights frameworks.

Children's perception of their city centre: a qualitative GIS methodological investigation in a Dutch city

Children represent a population group that is much neglected in the city planning process. Their perceptions, which are different from those of adults, are usually not incorporated in the design of cities. The aim of this paper is to present a qualitative GIS approach to capture children's perceptions of the urban environment. It gives a detailed insight into why certain perceptions occur and what the associated physical and social qualities are. The approach considers children as active participants and combines quantitative and qualitative methods. Twenty-eight children aged 10–17 were involved in examining the city-centre area of Enschede, the Netherlands. The results show both similarity and heterogeneity in perception (e.g. based on gender and age group) and the emergence of new location-specific qualities (e.g. natural elements, smart technologies, economic functions). It concludes with a discussion on the potential of incorporating this approach in urban planning processes.     

Women’s everyday spirituality in Diamond Way Buddhism: an auto-photographic study

The Western world is experiencing increasing popularity of new religious movements whose adherents tend to spirituality, a subjective, personal form of religion. These spiritual forms shape the spaces of everyday life, their meanings, perceptions, and experiences, which is starting to be reflected in new geographies of religion. In Czechia, one of the most rapidly growing new religious movements is Diamond Way Buddhism. This contribution focuses on how Diamond Way spirituality is lived and experienced in space. The paper explores this phenomenon using the method of auto-photography. We asked six women to photograph places important to them in their daily lives and interpret their spiritual meaning. This method allows exploration of women’s spirituality in the everyday spaces where it is perceived and experienced, such as kitchens, buses, or natural sites. The results show that women have a specific way of experiencing Buddhism in seemingly secular space which they describe through feminine characteristics of transcendence. Everyday spaces become spiritual through the subjects’ emotional and continual experiencing of Buddhism, while the officially sacred space of a Buddhist center is incorporated into everyday life activities of women. The division between sacred and secular spaces often described by scholars is therefore challenged.
