Coronavirus and the homeless: Why increasing police powers is not the answer

What would be a humane response to the needs of the most vulnerable in society during a humanitarian crisis? Lock them up — that’s what the new Emergency Coronavirus Bill proposes. The Government introduced it on Thursday (March 19) to Parliament

Service-level agreements for electronic services

The potential of communication networks and middleware to enable the composition of services across organizational boundaries remains incompletely realized. In this paper, we argue that this is in part due to outsourcing risks and describe the possible contribution of Service-Level Agreements (SLAs) to mitigating these risks. For SLAs to be effective, it should be difficult to disregard their original provisions in the event of a dispute between the parties. Properties of understandability, precision, and monitorability ensure that the original intent of an SLA can be recovered and compared to trustworthy accounts of service behavior to resolve disputes fairly and without ambiguity. We describe the design and evaluation of a domain-specific language for SLAs that tend to exhibit these properties and discuss the impact of monitorability requirements on service-provision practices

Efficient online monitoring of web-service SLAs

If an organization depends on the service quality provided by another organization it often enters into a bilateral service level agreement (SLA), which mitigates outsourcing risks by associating penalty payments with poor service quality. Once these agreements are entered into, it becomes necessary to monitor their conditions, which will commonly relate to timeliness, reliability and request throughput, at runtime. We show how these conditions can be translated into timed automata. Acceptance of a timed word by a timed automaton can be decided in quadratic time and because the timed automata can operate while messages are exchanged at runtime there is effectively only a linear run-time overhead. We present an implementation to derive on-line monitors for web services automatically from SLAs using an Eclipse plugin. We evaluate the efficiency and scalability of this approach using a large-scale case study in a service-oriented computational grid

Algorithms for efficient symbolic detection of faults in context-aware applications.

Context-aware and adaptive applications running on mobile devices pose new challenges for the verification community. Current verification techniques are tailored for different domains (mostly hardware) and the kind of faults that are typical of applications running on mobile devices are difficult (or impossible) to encode using the patterns of ldquotraditionalrdquo verification domains. In this paper we present how techniques similar to the ones used in symbolic model checking can be applied to the verification of context-aware and adaptive applications. More in detail, we show how a model of a context-aware application can be encoded by means of ordered binary decision diagrams and we introduce symbolic algorithms for the verification of a number of properties

Outlaw girls escape from prison: gender, resistance and playfulness

Prison resistance practices are increasingly understood as gendered and linked to subjectivation. This article builds on this growing body of knowledge, but with a different and largely under explored focus, namely the confrontational resistance practices of women political prisoners. The objective is to explore how gendered resistance practices disrupt dominant constructions of gender through the lens of the hidden preparations and implementation of a historical women’s escape. This is done through a gendered analysis of narrative and auto/biographical material of the 1976 prison break in Germany, in which four women of the Red Army Faction (RAF) and June 2nd Movement (J2M) escaped from the women’s prison in West Berlin . Drawing on the works of poststructuralist feminists, the article expands our theoretical understanding of resistance to include the recognition of playfulness and laughter in the processes of subjectivation. It argues that opening up gendered resistance practices to play and laughter, lets us see the women’s escape as a subversive reversal of the heroic, masculine prison break, in which their subjectivity as revolutionary violent women is revealed

Studi Gaya Desain Posmodern pada Interior Food Court Galaxy Mall di Surabaya

A food court is an important public facilty in a shopping centre. Apart from its generally large capacity and variety of cuisine served, the design of most foodcourts are also generally attractive.Their interior designs are able to affect the atmoshphere and mood of visitors.Many foodcourts in today's malls adopt the postmodern style in their design, for instance, the Galaxy Mall in Surabaya, which will be the object for case study in this research. The objective of this research is to investigate the implementation of the Post modern style in the interior elements of the food court that will be discussed in detail. The research findings show that the use of Post modern style can be seen in the spatial arrangement, interior elements such as floors, walls and ceilings, furnitures as well as decorative elements such as colour and material. All these elements adopted the Post Modern style in terms of ideology, concept, aim as well as design methodology. The concept of Contradiction has been applied in the two areas of the food court
