Consistency of replicated datasets in Grid computing
No full textData replication is a well-known technique used in distributed systems in order to improve fault tolerance and make data access faster. Several copies of a dataset are created and placed at different nodes, so that users can access the replica closest to them, and at the same time the data access load is distributed among the replicas. In today's Grid middleware solutions, data management services allow users to replicate datasets (i.e., flat files or databases) among storage elements within a Grid, but replicas are often considered read-only because of the absence of mechanisms able to propagate updates and enforce replica consistency. In this entry we analyze the replica consistency problem and provide hints
for the development of a Replica Consistency Service, highlighting the main issues and pros and cons of several approaches
FUNCTIONAL IMAGING IN RECTAL PROLAPSE
No full textImaging data has gained relevance in the preoperative assessment of severe pelvic organ prolapse, including vaginal vault descent, enterocele, rectocele and cystocele
Classification of internal and external rectal prolapse
No full textPhysical examination has traditionally been, and continues to be, the mandatory initial step in the evaluation of patients with constipation or faecal incontinence. This is because the initial treatment decision and the necessity of further investigations of patients with pelvic floor dysfunction depend on primary clinical assessment of the patient [1]. Even if authors [2] found good correlation between clinical assessment and defecography in high-grade intussusceptions when studying subjects with defecatory difficulties, several reports in the nonradiologic literature have documented the relative insensitivity of the history and physical examination in diagnosing the cause of constipation and detecting pelvic organ prolapse [11, 3-6]. The common clinical physical examination tends to underestimate the degree of prolapse and may be able to diagnose only 30-40% of rectal prolapse [7]. Therefore, the precise preoperative diagnosis supplied by defecography can help in the selection of a rationale treatment programme, placing the patient into a treatment-defined group, determining the type of operation and giving objective evidence for the corrective scope and degree of operation
Replica consistency in a Data Grid
No full textA Data Grid is a wide area computing infrastructure that employs Grid technologies to provide storage capacity and processing power to applications that handle very large quantities of data. Data Grids rely on data replication to achieve better performance and reliability by storing copies of data sets on different Grid nodes. When a data set can be modified by applications, the problem of maintaining consistency among existing copies arises. The consistency problem also concerns metadata, i.e., additional information about application data sets such as indices, directories, or catalogues. This kind of metadata is used both by the applications and by the Grid middleware to manage the data. For instance, the Replica Management Service (the Grid middleware component that controls data replication) uses catalogues to find the replicas of each data set. Such catalogues can also be replicated and their consistency is crucial to the correct operation of the Grid. Therefore, metadata consistency generally poses stricter requirements than data consistency. In this paper we report on the development of a Replica Consistency Service based on the middleware mainly developed by the European Data Grid Project. The paper summarises the main issues in the replica consistency problem, and lays out a high-level architectural design for a Replica Consistency Service. Finally, results from simulations of different consistency models are presented
Consensus Statement of the Italian Society of Colorectal Surgery (SICCR): management and treatment of complete rectal prolapse
No full textRectal prolapse, rectal procidentia, “complete” prolapse or “third-degree” prolapse is the full-thickness prolapse of the rectal wall through the anal canal and has a significant impact on quality of life. The incidence of rectal prolapse has been estimated to be approximately 2.5 per 100,000 inhabitants with a clear predominance among elderly women. The aim of this consensus statement was to provide evidence-based data to allow an individualized and appropriate management and treatment of complete rectal prolapse. The strategy used to search for evidence was based on application of electronic sources such as MEDLINE, PubMed, Cochrane Review Library, CINAHL and EMBASE. The recommendations were defined and graded based on the current levels of evidence and in accordance with the criteria adopted by the American College of Gastroenterology’s Chronic Constipation Task Force. Five evidence levels were defined. The recommendations were graded A, B, and C
Relaxed Data Consistency with CONStanza
No full textData replication is an important aspect in a Data Grid for increasing fault tolerance and availability. Many Grid replication tools or middleware systems deal with read-only files which implies that replicated data items are always consistent. However, there are several applications that do
require updates to existing data and the respective replicas. In this article we present a replica consistency service that allows for replica updates in a single-master scenario with lazy update synchronisation. The system allows for updates of (heterogeneous) relational databases, and it is designed to support flat files as well. It keeps remote replicas synchronised and partially (“lazily”) consistent. We report on
the design and implementation of a novel “relaxed” replica consistency service and show its usefulness in a typical application use case

Variations on the Author
No full text“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
