Junos OS Security Configuration Guide

This preface provides the following guidelines for using the Junos OS Security Configuration Guide: • J Series and SRX Series Documentation and Release Notes on page xli • Objectives on page xlii • Audience on page xlii • Supported Routing Platforms on page xlii • Document Conventions on page xlii • Documentation Feedback on page xliv • Requesting Technical Support on page xliv Juniper Networks supports a technical book program to publish books by Juniper Networks engineers and subject matter experts with book publishers around the world. These books go beyond the technical documentation to explore the nuances of network architecture, deployment, and administration using the Junos operating system (Junos OS) and Juniper Networks devices. In addition, the Juniper Networks Technical Library, published in conjunction with O'Reilly Media, explores improving network security, reliability, and availability using Junos OS configuration techniques. All the books are for sale at technical bookstores and book outlets around the world. The current list can be viewed at http://www.juniper.net/books .Junos OS for SRX Series Services Gateways integrates the world-class network security and routing capabilities of Juniper Networks. Junos OS includes a wide range of packet-based filtering, class-of-service (CoS) classifiers, and traffic-shaping features as well as a rich, extensive set of flow-based security features including policies, screens, network address translation (NAT), and other flow-based services. Traffic that enters and exits services gateway is processed according to features you configure, such as packet filters, security policies, and screens. For example, the software can determine: • Whether the packet is allowed into the device • Which firewall screens to apply to the packet • The route the packet takes to reach its destination • Which CoS to apply to the packet, if any • Whether to apply NAT to translate the packet’s IP address • Whether the packet requires an Application Layer Gateway (ALG

Designing sound : procedural audio research based on the book by Andy Farnell

In procedural media, data normally acquired by measuring something, commonly described as sampling, is replaced by a set of computational rules (procedure) that defines the typical structure and/or behaviour of that thing. Here, a general approach to sound as a definable process, rather than a recording, is developed. By analysis of their physical and perceptual qualities, natural objects or processes that produce sound are modelled by digital Sounding Objects for use in arts and entertainments. This Thesis discusses different aspects of Procedural Audio introducing several new approaches and solutions to this emerging field of Sound Design.Em Media Procedimental, os dados os dados normalmente adquiridos através da medição de algo habitualmente designado como amostragem, são substituídos por um conjunto de regras computacionais (procedimento) que definem a estrutura típica, ou comportamento, desse elemento. Neste caso é desenvolvida uma abordagem ao som definível como um procedimento em vez de uma gravação. Através da análise das suas características físicas e perceptuais , objetos naturais ou processos que produzem som, são modelados como objetos sonoros digitais para utilização nas Artes e Entretenimento. Nesta Tese são discutidos diferentes aspectos de Áudio Procedimental, sendo introduzidas várias novas abordagens e soluções para o campo emergente do Design Sonoro

The electronic patient record: a linguistic ethnographic study in general practice

PhDElectronic Patient Records (EPRs) are in widespread use in UK general practice. Although often taken-for-granted by clinicians, managers, administrators and patients, there is limited understanding of how EPRs shape care processes and healthcare interactions in this setting. The EPR is ubiquitous in practice, but its social impact remains under-researched. In this thesis I present a novel approach to examining the role of the EPR, which draws on ethnography and discourse analysis. My work is based on eight months of ethnographic observation in clinical and administrative areas of two general practices. This included observation of clinical consultations, with videorecording of the interpersonal interaction and contemporaneous screen capture of the EPR. This opens up the ‘EPR-in-use’ to detailed scrutiny. In my analysis, which draws particularly on the theoretical work of Goffman and Bakhtin, I pay close attention to the detail of local action and interaction, whilst maintaining sensitivity to the wider context of the general practice organisation. This makes an original contribution to the emerging field of linguistic ethnography. My analysis shows that the EPR contributes to shaping and regimenting interactions and care practices in profound ways, both within the consultation and more widely in general practice organisations. It creates new opportunities, but also creates new demands and tensions. In particular, it sharpens the tension between different ways of framing the patient – the patient as ‘individual’ and the patient as ‘one of a population’ – the latter a more institutional version of the patient. This creates what I have called a ‘dilemma of attention’ for clinicians engaged in patient care. I show ways in which the EPR contributes to the bureaucratisation of care, the construction and circulation of authority within and beyond the consultation, and the production of new notions of patienthood and professional habitus in contemporary general practice

Maritime expressions:a corpus based exploration of maritime metaphors

This study uses a purpose-built corpus to explore the linguistic legacy of Britain’s maritime history found in the form of hundreds of specialised ‘Maritime Expressions’ (MEs), such as TAKEN ABACK, ANCHOR and ALOOF, that permeate modern English. Selecting just those expressions commencing with ’A’, it analyses 61 MEs in detail and describes the processes by which these technical expressions, from a highly specialised occupational discourse community, have made their way into modern English. The Maritime Text Corpus (MTC) comprises 8.8 million words, encompassing a range of text types and registers, selected to provide a cross-section of ‘maritime’ writing. It is analysed using WordSmith analytical software (Scott, 2010), with the 100 million-word British National Corpus (BNC) as a reference corpus. Using the MTC, a list of keywords of specific salience within the maritime discourse has been compiled and, using frequency data, concordances and collocations, these MEs are described in detail and their use and form in the MTC and the BNC is compared. The study examines the transformation from ME to figurative use in the general discourse, in terms of form and metaphoricity. MEs are classified according to their metaphorical strength and their transference from maritime usage into new registers and domains such as those of business, politics, sports and reportage etc. A revised model of metaphoricity is developed and a new category of figurative expression, the ‘resonator’, is proposed. Additionally, developing the work of Lakov and Johnson, Kovesces and others on Conceptual Metaphor Theory (CMT), a number of Maritime Conceptual Metaphors are identified and their cultural significance is discussed
