Experiencing the armed struggle : the Soweto generation and after
No full textIncludes bibliographical references (p. 354-369).This study explores the experiences of the rank-and-file soldiers of Umkhonto we Sizwe and the Azanian People's Liberation Anny. Extensive interviews by the author and other researchers reveal the voices of the soldiers themselves. The African National Congress and Pan African Congress archives at the University of the Western Cape and the University of Fort Hare supplement and verify these oral testimonies, as do some published sources. Most previously published materials about the armed struggle against apartheid have already focused on diplomacy, strategy and tactics, operations, leadership, and human rights abuses to the neglect of the soldiers' actual experiences. This study complements these with significant new oral history materials from the Soweto generation of soldiers and their successors. When dealing with MK, many authors have documented issues of the camp structure in Angola, and operations inside South Africa, so much of this detail is only addressed briefly, leaving space to explore the soldiers' experiences. In the case of APLA, very little has been written on its history, and more detail is provided on these subjects. This study therefore deals with the soldiers' politicisation and motivation for joining the armed struggle, their experiences in leaving South Africa and training in exile, the crises in exile which limited their effectiveness for a time, their return to fight in South Africa, and their difficulties in the "new" South Africa. These materials reveal that vast problems remain facing these veterans of the struggle against apartheid, and that they have the potential, if properly supported and employed, to contribute substantially to the development of present day South Africa. Conversely, if their neglect continues, they also have the potential to bring vast harm to the country. Further use of the investigative tools of oral history, especially if extended to the former soldiers' vernacular languages, is necessary to augment the history of South Africa, and these soldiers' contributions
Conservation in an Islamic context a case study of Makkah
No full textThe Holy Qu’ rān contains many injunctions for Muslims to respect and conserve the natural environment but few address the built environment. Habitat at the time of the Prophet (PBOH) was in the vernacular and relatively impermanent. The first habitat was the cave, the second the tent and then simple flat roofed buildings of post and lintel construction made of mud and rubble. Later buildings were not indigenous but reflected the architectural styles and techniques of Muslim pilgrims from beyond the Arabian Peninsula. Permanent exotic buildings were later erected as reminders of holy places and events. This work advances a case to restore and preserve historic and religious sites in Makkah, Saudi Arabia. Makkah is the destination for millions of Muslim pilgrims who annually pay homage to Allah during the occasions of Hajj, Ramadan and Umra. The tranquillity and peaceful ambience that one associates with the holiest of Islamic experiences have, over the years, given way to jostling crowds of people who must be expediently housed, fed, transported, and protected. Due to the lack of planning and the insensitive but profitable development of the city, Makkah is in grave danger of becoming a bustling metropolis instead of a sanctuary where pilgrims gather to perform their religious rites and reaffirm their dedication to Allah. The author calls for professional planning and international cooperation to guide future development for this expanding and sensitive area. The author's ideas are grounded in practical and aesthetic study, therefore, the political, environmental and economic issues are examined in relationship to religious, historic and artistic values. The author makes proposals for a future Makkah that would provide pilgrims with the physical comforts, security, and serene environment they deserve—without destroying the city they came to visit. The author discusses preservation and conservation in the western world and the need for their acceptance in Muslim countries, the former being an aesthetic and intellectual concept sustained by law and the latter being the prescribed free expression of the individual unhindered by material considerations. Both worlds are rapidly being overwhelmed by materialism, but body, mind and spirit combine in making us aware of our surroundings and the way in what we see around us has come into being

Incremental Maintenance Of Materialized XQuery Views
No full textKeeping views fresh by maintaining the consistency between materialized views and their base data in the presence of base updates is a critical problem for many applications, including data warehousing and data integration. While heavily studied for traditional databases, the maintenance of XML views remains largely unexplored. Maintaining XML views is complex due to the richness of the XML data model and the powerful capabilities of XML query languages, such as XQuery.
This dissertation proposes a comprehensive solution for the general problem of maintaining materialized XQuery views. Our solution is the first to enable the maintenance of a large class of XQuery views including XPath expressions, FLWOR expressions, and Element Constructors. These views may contain arbitrary result construction and arbitrary grouping and join operations. Our solution also supports the unique order requirements of XQuery including source document order and query order.
The contributions of this dissertation include: (i) an efficient solution for supporting order in XML query processing and view maintenance, (ii) an identifier-based technique for enabling incremental construction of XML views, (iii) a mechanism for modeling and validating source XML updates, (iv) a counting algorithm for supporting view maintenance on delete and modify updates, (v) an algebraic solution for propagating bulk XML updates, and (vi) an efficient mechanism for refreshing materialized XML views on propagated updates. We provide proofs of correctness of our proposed techniques for materialized XQuery maintenance.
We have implemented a prototype of our view maintenance solution on top of the Rainbow XML query engine, developed at WPI. Our experiments confirm that our solution provides a practical and efficient solution for maintaining materialized XQuery views even when handling heterogeneous batches of possibly large source updates.
Our solution follows the widely adopted propagate-apply framework for view maintenance common to all mainstream query engines. That is, our solution produces incremental maintenance plans in the same algebraic language used to define the views. These plans can thus be optimized and executed by standard query processing techniques. Being compatible with standard frameworks paves the way for our XML view maintenance solution to be easily adopted by existing database engines

An Efficient and Incremental System to Mine Contiguous Frequent Sequences
No full textMining frequent patterns is an important component of many prediction systems. One common usage in web applications is the mining of users' access behavior for the purpose of predicting and hence pre-fetching the web pages that the user is likely to visit.
Frequent sequence mining approaches in the literature are often based on the use of an Apriori-like candidate generation strategy, which typically requires numerous scans of the potentially huge sequence database. In this paper we instead introduce a more efficient strategy for discovering frequent patterns in sequence databases that requires only two scans of the database. The first scan obtains support counts for subsequences of length two. The second scan extracts potentially frequent sequences of any length and represents them as a compressed frequent sequences tree structure (FS-tree). Frequent sequence patterns are then mined from the FS-tree. Incremental and interactive mining functionalities are also facilitated by the FS-tree. As part of this work, we developed the FS-Miner, an system that discovers frequent sequences from web log files. The FS-Miner has the ability to adapt to changes in users' behavior over time, in the form of new input sequences, and to respond incrementally without the need to perform full re-computation. Our system also allows the user to change the input parameters (e.g., minimum support and desired pattern size) interactively without requiring full re-computation in most cases.
We have tested our system using two different data sets, comparing it against two other algorithms from the literature. Our experimental results show that our system scales up linearly with the size of the input database. Furthermore, it exhibits excellent adaptability to support threshold decreases. We also show that the incremental update capability of the system provides significant performance advantages over full re-computation even for relatively large update sizes

Out-of-hospital cardiac arrest survival in Beirut, Lebanon
No full textBackground: Out-of-hospital cardiac arrest (OHCA) is used to evaluate the performance of the emergency medical service (EMS) system. Our study examined the characteristics and outcomes of OHCA cases presenting to a tertiary care center in Beirut, Lebanon. Methods: A retrospective chart review of all adult OHCA patients admitted to the emergency department (ED) over a 3-year period was carried out. Data collection and analysis was performed using the Utstein guidelines. Results: A total of 214 OHCA patients were presumed to have cardiac etiology; of them 205 (95.8percent) underwent ED resuscitation. The mean age was 69±15.4 years. More than half of the patients (54.2percent) were witnessed, but unfortunately the bystander cardiopulmonary resuscitation rate was low (4.2percent). Most of them were transported by EMS (71.5percent). An automatic external defibrillator was rarely used (0.9percent). Asystole was the predominant presenting rhythm in ED (81.8percent). Eleven patients (5.5percent) survived to hospital discharge and five (45.4percent) had good neurological outcome. Conclusion: The OHCA survival rate in Beirut, Lebanon, is low. Bystander cardiopulmonary resuscitation and early defibrillation should be prioritized to achieve better outcomes. © 2014 Wolters Kluwer Health | Lippincott Williams and Wilkins.El Sayed Mazen J, 2013, Prehosp Disaster Med, V28, P163, DOI 10.1017-S1049023X12001732; Fraga-Sastrías Juan Manuel, 2009, Prehosp Disaster Med, V24, P121; HERLITZ J, 1994, RESUSCITATION, V28, P27, DOI 10.1016-0300-9572(94)90051-5; Hiltunen P, 2012, SCAND J TRAUMA RESUS, V20, DOI 10.1186-1757-7241-20-80; Hostler D, 2010, RESUSCITATION, V81, P826, DOI 10.1016-j.resuscitation.2010.02.005; Liu JM, 2008, PREHOSP EMERG CARE, V12, P339, DOI 10.1080-10903120802101330; McNally Bryan, 2011, Morbidity and Mortality Weekly Report, V60, P1; Myers JB, 2008, PREHOSP EMERG CARE, V12, P141, DOI 10.1080-10903120801903793; Rittenberger JC, 2011, RESUSCITATION, V82, P1036, DOI 10.1016-j.resuscitation.2011.03.034; CHAMBERLAIN D, 1991, RESUSCITATION, V22, P1, DOI 10.1016-0300-9572(91)90061-30
Interventions for preventing oral mucositis for patients with cancer receiving treatment
No full textBackground Treatment of cancer is increasingly more effective but is associated with short and long term side effects. Oral side effects remain a major source of illness despite the use of a variety of agents to prevent them. One of these side effects is oral mucositis (mouth ulcers). Objectives To evaluate the effectiveness of prophylactic agents for oral mucositis in patients with cancer receiving treatment, compared with other potentially active interventions, placebo or no treatment. Search strategy Electronic searches of Cochrane Oral Health Group and PaPaS Trials Registers (to 1 June 2010), CENTRAL (The Cochrane Library 2010, Issue 2), MEDLINE via OVID (1950 to 1 June 2010), EMBASE via OVID (1980 to 1 June 2010), CINAHL via EBSCO (1980 to 1 June 2010), CANCERLIT via PubMed (1950 to 1 June 2010), OpenSIGLE (1980 to 2005) and LILACS via the Virtual Health Library (1980 to 1 June 2010) were undertaken. Reference lists from relevant articles were searched and the authors of eligible trials were contacted to identify trials and obtain additional information. Selection criteria Randomised controlled trials of interventions to prevent oral mucositis in patients receiving treatment for cancer. Data collection and analysis Information regarding methods, participants, interventions, outcome measures, results and risk of bias were independently extracted, in duplicate, by two review authors. Authors were contacted for further details where these were unclear. The Cochrane Collaboration statistical guidelines were followed and risk ratios calculated using random-effects models. Main results A total of 131 studies with 10,514 randomised participants are now included. Nine interventions, where there was more than one trial in the meta-analysis, showed some statistically significant evidence of a benefit (albeit sometimes weak) for either preventing or reducing the severity of mucositis, compared to either a placebo or no treatment. These nine interventions were: allopurinol, aloe vera, amifostine, cryotherapy, glutamine (intravenous), honey, keratinocyte growth factor, laser, and polymixin/tobramycin/amphotericin (PTA) antibiotic pastille/paste. Authors' conclusions Nine interventions were found to have some benefit with regard to preventing or reducing the severity of mucositis associated with cancer treatment. The strength of the evidence was variable and implications for practice include consideration that benefits may be specific for certain cancer types and treatment. There is a need for further well designed, and conducted trials with sufficient numbers of participants to perform subgroup analyses by type of disease and chemotherapeutic agent. This review is published as a Cochrane Review in the Cochrane Database of Systematic Reviews 2010, Issue 12. Cochrane Reviews are regularly updated as new evidence emerges and in response to comments and criticisms, and the Cochrane Database of Systematic Reviews should be consulted for the most recent version of the Review.</p
Effect of Nursing Care Protocol on Nurses' Competency regards Children with Thalassemia
No full textAbstract: Thalassemia is estimated to affect one thousand children out of every 1.5 million live births in Egypt. Aim: This study aimed to evaluate the effect of nursing care protocol on nurses' knowledge and practice provided to children with thalassemia. Design: A quasi-experimental (pre, post, and follow-up test) was used. Setting: This study was conducted in Pediatric Department at El Menoufia University Hospital, Egypt. Sample: A purposive 35 pediatric nurses providing care to children with thalassemia. Instruments: A structured interview questionnaire to assess nurses’ knowledge about thalassemia and an observational checklist to assess nurses’ practice provided to children with thalassemia. Results: A highly statistically significant difference was found between pre and post-tests and between post and follow-up tests. It noted that none of the studied nurses had competent nursing practice on the pre-test. Meanwhile, all of them (100%) had competent nursing practice on post-test. Also, a highly statistically significant positive correlation between total knowledge and total practice score. Conclusion: Nurses who received nursing care protocol had a higher level of knowledge and practice on post and follow-up tests compared to the pre-test. Recommendations: Continuous training program for developing nurses' knowledge and practices regarding nursing care protocol of thalassemia.
Keywords: Nursing care, Protocol, Competency of care, Children, Thalassemia.
