维普数据库Z39.50服务端系统设计方案 总被引:1,自引:0,他引:1
介绍了维普数据库Z39.50服务端系统的设计方案,该方案有两条解决途径:基于TCP/IP的Z39.50服务端系统和基于HTTP的SRU服务端系统,笔者将这两种思路做了比较。本系统突破了传统Z39.50协议只运用于对书目数据的提供,而是提供电子期刊数据,这是本方案的特色所在。 相似文献

This article presents the intervention process carried out on a work of art created by artist Yolanda Gutiérrez Acosta, using a series of ephemeral materials such as butterfly wings and agave thorns. The work, an installation from 2002, is entitled ‘Efímeras’ (‘Ephemera’) and consists of 12 flowers mounted on acetate sheets and attached to the same with vinyl acetate copolymers and acrylic acid esters (Mowilith®). These flowers are installed on the floor in a bed of dried flowers. The conservation of contemporary art can lead to some previously unimaginable problems for restorers. Current works of art are somewhat material in nature, but they also have a conceptual dimension that is essential for their artistic interpretation. The artist’s participation in the decision-making process prior to the restoration was quite useful. The passage of time, its effect on the work, and the need to understand the possibility of the demise and destruction of the work were implicit as of the onset of its creation, such that, according to the artist, we are forced to reflect upon the possibilities of its future state. 相似文献

This article proposes that restorative justice practices (RJPs), as used in New Zealand schools, are better understood as an instrument of social development than a behaviour management practice. Concerns about the achievement of Māori students are relocated, from an individualised psychological and pedagogical problem to an interdisciplinary context of historical and social development. Social constructionist theory is suggested as a lens through which RJPs in schools may be seen as the intentional production of respectful social relationships, rather than as behaviour management. A restorative process has the productive capacity to restore healthy relational functioning, both for those who have been offended against and those who have offended. It is argued that the primary function of restorative justice in schools is not about resolving specific conflicts, but rather, about the production and maintenance of respectful relationship, which is the antithesis of colonised relationship. Such a position reflects accountability on a communal, rather than individualised basis, and accords with recent moves in the United Nations Development Programme to look at Human Development as building agentive capacity. 相似文献

ABSTRACT Press credentialing practices are a vital, yet understudied site of scholarly research on journalistic norms and practices. Press credentialing not only structures internal professional hierarchies, but they also signify the boundaries of the journalistic field itself. This paper explores the legal and theoretical implications of press credentialing to cover the United States Congress, drawing on the concepts of boundary work and journalistic authority to demonstrate the material impact of the space between fields on professional legitimation in journalism. Using WorldNetDaily (WND) as a case study, I argue that the Standing Committee of Correspondents (SCC) occupies a hybrid boundary zone between the journalistic and political fields, generating a unique tension in First Amendment jurisprudence that places journalists in a paradoxical role as both the professional embodiments of free speech and its constitutional steward. The resulting jurisdictional conflict between the SCC and WND extends the relational model of journalistic authority by articulating how journalist-state relations can fundamentally augment the process of legitimation at its fuzzy boundaries. The relevance and implications for press credentialing practices in the digital age are discussed. 相似文献

ABSTRACT This essay reads the Latina/o/x migrant vernacular discourses that emerge out of pro-migrant activism. Anzaldúa’s notion of mestizaje – a logic of border consciousness – is put into conversation with Deleuze’s notion of nomad thought – a logic of movement – to inform a rhetorical strategy for reading the vernacular archive of social movement discourse. The “No Papers, No Fear” is one such social movement that demonstrate the logic of mestizaje/nomadism in their communication strategies. This study illuminates three tensions that define the ways Latina/o/x migrants in the US navigate the spaces of citizenship: tensions between movement/stasis, migrant identity/national identity, and fear/safety. 相似文献

There is evidence that pupils with weak literacy skills struggle on transition to secondary school. Many experience a drop in attainment in the summer break between the two. A British government‐funded programme of rigorously designed research on boosting literacy at transition had (by 2015) found only four of 15 interventions evaluated had positive effects. This small‐scale quasi‐experimental study investigated the effectiveness of support for pupils with mild literacy difficulties on transition to secondary school. Thirty‐two pupils in three schools were involved; half received the programme. Pairs were matched on reading, spelling, age and gender. Intervention was designed around the individual needs of each pupil, focusing variously on language skills, writing, reading and spelling. The group receiving the programme made modest gains in spelling, reading efficiency and single word reading. The comparison group lost ground, relatively, in all three areas. The results suggest a promising line for more rigorous investigation. 相似文献
