ISI协议的符号模型检验分析

电子商务协议的非否认性与公平性问题已成为电子商务和信息安全领域研究的热点。本文建立了网络支付协议ISI的有限状态机模型,并用SMV检验工具对其两个重要特性———非否认性与公平性进行了分析检验,发现了ISI协议不满足公平性。结果表明利用符号模型检验方法分析检验电子商务协议的新特性是行之有效的。     

贾宝玉与浮士德形象之比较

贾宝玉形象反映了中国早期启蒙主义者以及那些怀才不遇、壮志难踌的士大夫们的思想追求和价值取向;浮士德形象反映了西方近代人的精神追求。不同的时代精神、文化背景赋予悲剧人物形象以不同的象征内涵。

自然在现代室内空间中的表现趋势

自然是一切分析原则的源泉,其动态发展的历程,为设计提供着形式的创新、欣赏的快感与文化的传承同时,室内空间中对自然的表现形式也在不断发展,正如美国建筑理论家詹克斯在《动荡世界中的建筑》所言,建筑界正在“回归不同的自然”     

复杂系统中的人误屏障分析

从预防与保护两方面阐述了复杂系统中屏障的概念;从性质的角度将屏障分为实体屏障、功能性屏障、象征性屏障及非物质屏障。同时也说明了屏障的起源、位置、目的等不能作为分类基础的原因。在此基础上,创造性地将屏障的概念延伸到人与社会系统之中,即把人与社会也分别看成一类综合性的特殊屏障,并将其剖析成上述四类性质的屏障;然后,集中讨论如何使用屏障分类进行事故分析,以找出能预防或减少失误的各类屏障;最后,剖析了屏障与失误模式之间的关系,以阐明屏障分析的方法。     

Welcoming Refugees and the Cultural Wealth of Cities: Intersections of Urban Development and Refugee Humanitarianism

In a context of rising nativism, cities across liberal democracies are enacting agendas to ‘welcome’ migrants and refugees. Existing scholarship examines this contentious political geography as reflecting either accommodative or restrictive responses to local immigrant populations. Through this lens, pro‐immigrant policies and dynamics are seen to recognize and support a set of pre‐defined immigrant ‘interests’, with the pertinent question being which local actors initiate processes of incorporation and why. Drawing on urban scholarship, this article offers an alternative framework through an analysis of resettled refugees’ experiences within the ‘welcoming agenda’ of Pittsburgh, Pennsylvania. I show that this agenda is tethered to postindustrial ideologies of urban development, which see building and promoting ‘diversity’ as an economic exigency. As such, locally resettled refugees are incentivized to participate in a ‘symbolic economy’ valuing images of diversity, cosmopolitanism and immigrant contribution. Refugees gain access to resources, recognition and decision makers through participation in this symbolic economy, a process constituting a previously unexamined form of incorporation. I advance the concept of the ‘welcomed refugee’ to organize thinking about this process and call for critical attention to the forms of incorporation fostered in pro‐immigrant, cosmopolitan, substate settings.     

Using photographs in interpreting cultural and symbolic meaning: A reflection on photographs of the Korean Association for Government Accounting

Building on a sociological tradition of using photographs as a methodology, we suggest that accounting researchers more fully utilize photographs to understand accounting actors’ everyday lives. While most accounting studies have focused on the photographic imagery in published documents, such as corporate annual reports, a few authors found photographs can highlight how physical artefacts can deliver symbolic messages. We explored photographs drawn from the Korean Association for Government Accounting (KAGA) to illustrate how social actors used physical artefacts. To guide our analysis, we relied on Bourdieu’s theorization of how physical artefacts reflect forms of capital. We argue that the use of photographs as a methodology provides a deeper insight into the cultural and social meanings of physical artefacts as a form of language open to multiple interpretations by both the author and the reader.

Brand death: A developmental model of senescence

Drawing on literature underpinning brand management in marketing, product life cycles in economics, fads in sociology and aging in biology, this paper argues that brand demise is inevitable and not necessarily caused by managerial incompetence. Rather, this demise is a natural part of a brand's developmental process, instigated by consumers seeking to satisfy not only their material needs (constitutive utility), but also their self-image (symbolic utility). This paper presents a model of brand senescence to explain this phenomenon and concludes with a discussion of the implications for managerial practice and marketing theory.
