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

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.

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
Investigation on the possible application of Natural fibres (Abaca fibres) as reinforcement in concrete to create ductility
No full textAlmost 3500 years ago, Egyptians used straw to reinforce mud blocks for construction purposes. Later on, concrete and metals were introduced and the interest for NFC was reduced. In 1900 asbestos fibres were introduced to produce light weight and durable elements; however in 1970 it was discovered that asbestos is unhealthy. Therefore, in 20th century the idea of using natural fibres in materials was resumed which lead to extensive variety of fibre reinforced cement-based materials. Different types of fibres have been used as reinforcement, e.g. polyvinyl alcohol and Polyethene and natural fibres. Natural fibres are renewable resources. Less production energy is required for the production and it’s producible with low investment at low cost, but it has inconstant properties compared with synthetic fibres. Different researches have shown, that by using plant fibres, i.e.; Coir, Sisal, Jute, Hibiscus and Palm in cement-based materials, the compressive strength of the composites decreases with increasing fibre length and percentage. On the other hand, the flexural strength and toughness of the composites increases. Due to addition of fibres in the concrete the amount of the plastic shrinkage and autogenous shrinkage can also be reduced. Amongst the natural fibres, Abaca fibre was chosen and different experiments were performed to investigate the material properties of Abaca fibres and their behavior in concrete which is required to develop composites that show strain-hardening behavior with multiple cracks. The experiments showed that the Abaca fibres have an elliptical shape. It has a width of 100 - 400 µm and it consists of elongated elementary fibres. The tensile strength of Abaca fibre is 604 - 1104 MPa and its MOE is 14.92 - 33.61 GPa. Abaca fibres swell with an average diameter of 11.02% in a humid environment. Furthermore, Abaca fibres were treated with NaOH, Na2SiO3, C2H4O2, NaOH+C2H4O2 and H2O to reduce its hydrophilicity. As a result the surface of the Abaca fibres seemed to be damaged, but no fibre disintegration occurred. The Abaca fibres treated with H2O showed a very high reduction of -OH groups, while most of the treatments lead to an increase of -OH groups. Due to the treatment, the Abaca fibres tend to stick to each other. The effect of different treatments on the moisture absorption of the Abaca fibres was also investigated. Abaca fibres treated with NaOH + C2H4O2 and C2H4O2 exhibited the lowest moisture absorption behavior. Finally, different mixtures were casted using randomly distributed Abaca fibres to develop ductile composites and tested under compression and bending. The content of cement was reduced and replaced with limestone powder. The compressive strength of the specimens reinforced with Abaca fibres remained the same as unreinforced ones. Under bending test, the composites reinforced with Abaca fibres (treated and untreated) showed strain-hardening behavior with multiple cracks, due to increase of paste in the mixture by applying particle size distribution method. Also, single Abaca fibre pullout tests were conducted, but the results showed very low interfacial shear strength. Moreover, combined loading (freeze & thaw and bending) were performed. Under combined loading, the specimens showed strain-softening behavior. From all of the conducted experiments, it can be concluded that Abaca fibres can be used as possible reinforcement in cement-based materials (e.g. concrete) to create ductile composites, although the flexural strength, toughness and ductility is much lower than other fibre reinforced composites.Materials and EnvironmentStructural EngineeringCivil Engineering and Geoscience
Sectoral allocation by gender of Latin American workers over the liberalization period of the 1990s
No full textThe recent restructuring of Latin American economies has renewed interest in the effects of trade liberalization, on labor markets, and on the gender division of labor. The author does not attempt to establish casuality between economic reforms, and the types of jobs that men and women hold. Instead, she provides a detailed description of the trends in male, and female formal, and informal sector participation during the economic reform period in Argentina, Brazil, and Costa Rica. The author first compares the gender composition of the formal, informal wage, and self-employment sectors in a year before reforms (1988 for Argentina, 1989 for Brazil, and Costa Rica), and a year after reforms implementation (1997 for Argentina, 1995 for Brazil and Costa Rica). Although women continued to be more likely than men to work in the informal wage sector, there is no trend of"masculinization"or"feminization"of the informal sector, or any other. Instead, in Argentina men have overtaken women as the most prevalent workers in the informal wage sector, while in Brazil, the opposite has occurred (as men move into self-employment). In Costa Rica there have been no statistical, observable changes. The author then considers the distribution across sectors within each gender group, to identify whether men, and women are more likely to select different sectors in the post-reform period relative to the pre-reform period. Among both men, and women in all three countries (except Brazilian men), workers have become more likely to hold informal wage jobs, and less likely to hold formal sector jobs. Trends in human capital accumulation explain these changes for both men, and women, while changes in gender roles, primarily in homecare and marriage, do not seem to have an effect.Health Monitoring&Evaluation,Labor Policies,Population&Development,Public Health Promotion,Environmental Economics&Policies,Health Monitoring&Evaluation,Environmental Economics&Policies,Population&Development,Banks&Banking Reform,Work&Working Conditions
