On Tuesday, 27 November 1095, at the Council of Clermont, Pope Urban II made an appeal for a military expedition to fight for brethren in the Byzantine Empire and to liberate Jerusalem. The appeal, which was taken up was very successful. The result of the First Crusade was that the Latin States of the East were born: the county of Antioch, the county of Edessa, the county of Tripoli and the kingdom of Jerusalem. As time went by, the Crusades to the Holy Land became weakened. Finally, on 28th, May 1291, the remainder of the Holy Land (Acre) fell into Mamluk hands. In the period of the Crusades, the Crusade affected two great effects to the outside Western world. First, in April 1204, the Fourth Crusaders occupied Constantinople, which was the heart of the Byzantine Empire. It was the greatest sacking of Byzantine. Second, Saladin the most famous of Muslim heroes appeared on the scene. He recaptured Jerusalem (2 October 1187) and roused the sprit of jihad. At the present time, many leaders of Islam countries and terrorists groups regard themselves as successors of Saladin. On September 11, 2001, a group of 19 Muslim Arab terrorists hijacked four passenger planes en route across the United States. The immediate death toll was estimated at about three thousand civilians. After the attack of September 11, President Bush labelled the attacks as ‘acts of war’ and declared war on terrorism. On 29 January 2002, President Bush said that America would act against an ‘Axis of Evil’ formed by Iran, Iraq and North Korea. He accused these countries of developing weapons of mass destruction. On 20 March 2003, U.S. troops and allied troops launched an invasion on Iraq without the sanction of the UN Security Council. Finally, on May 1, 2003, Bush declared his victory and announced the end of a “major combat operation” in Iraq. Bush adduced three reasons for attacking Iraq. First, Iraq possessed weapons of mass destruction. Second, the Iraqi government had persistently violated human rights, and routinely used torture and carried out summary executions. Third, the regime of Saddam Hussein was implicated in transnational terrorism and, specifically, in the attacks of September 11. I tentatively conclude that Bush lacked the necessary evidence, but he, nevertheless, attacked Iraq. In the period of the Crusades or even nowadays, it is difficult to keep the peace between Islam and Christianity. Our duty is not to conquer Islam by war but to preach the Gospel in peaceful ways, and then it is necessary for us to learn peaceful coexistence. / Dissertation (MA(Theology))--University of Pretoria, 2008. / Church History and Church Policy / unrestricted

The purpose of this case study is to determine the influence of the curriculum used by the Guatemalan Municipal Orchestra (GMO) upon the social interactions of its members. Social interactions include relations with families, teachers, and music colleagues. To determine this influence, the researcher framed the study using three main components: the impact of music in the development of children’s social skills; the curricula forming educational processes; and the characteristics of the Venezuela musical program, El Sistema. These foundations are explored via the tenets of participatory literacy. The data collection included interviews, surveys, and observation of students, parents, teachers, and administrative personnel. Two primary themes emerged from the data analysis: the development of a sense of community and the presence of intrinsic and external motivators implicit in the GMO environment. The final analysis suggests that curricular practices in the GMO positively influenced the development of students’ social interactions.

In vitro studies of drug permeability are traditionally carried out using cultured monolayers of epithelial cell lines grown on semi permeable membranes. Caco-2 cells, which are colon-derived, spontaneously form polarised cell layers when cultured in vitro which are akin to an epithelium of enterocyte-like cells. The Caco-2 model has been developed as a powerful in vitro tool in the early assessment of human drug permeability and is even approved by regulatory agencies for biowaver applications (i.e. in vitro tests in lieu of in vivo animal experiments). As Caco-2 cells are derived from colon tissue they represent a more formidable barrier to drug absorption than the upper regions of the intestine which is where the majority of oral drugs permeate into the body. Whilst the Caco-2 model, alongside other in vitro methods, has provided a significant means to understand the mechanics of drug permeability. Many researchers have sought to improve upon the existing unicellular model; it is hoped that this will result in a more relevant and predictive model for researchers to test new drugs but also to dissect cellular cross talk and to probe cell-matrix interactions. Myofibroblasts are a niche cell type located subjacent to epithelial tissues which regulate the integrity, growth and differentiation of the overlying epithelium. In this study the co-culture of human epithelial cell lines with a myofibroblast cell line, CCD-18co, were investigated to study how myofibroblasts influence the barrier integrity of epithelia in vivo. Additionally, nanofibre scaffolds produced by electrospinning were explored as 3-dimensional and topographically relevant cell scaffolds to support the growth of intestinal cells in vitro. In a traditional transwell format, cultured epithelial lines Caco-2 (intestinal), HT-29 (intestinal) and Calu-3 (airway) in co-cultures with CCD-18co revealed cell-line specific response with respect to the modulation of barrier integrity. The mechanism of the modulation was confirmed to be mediated through paracrine signalling by using myofibroblast conditioned media. Fibre scaffolds which mimic the fibrillar nature of the extra cellular matrix and basement membrane were produced by electrospinning using the polymer, poly (ethylene terephthalate). Nanofibre scaffolds were characterised and further optimised for cell culture with surface coating with collagen to achieve adequate cell attachment and confluence. Work was also conducted to incorporate villi architectures into the fibre scaffolds; the potential of this ambition was investigated by using models produced by rapid prototyping. These models, which demonstrated good fidelity with the actual villi dimensions found in vivo, were used during the electrospinning process to shape the polymer scaffolds towards the geometry found in intestinal tissue. A number of molecular tracers and model drug compounds were used to evaluate the permeability profiles of Caco-2 monocultures, Caco-2/CCD-18co co-cultures cultured on the two different culture substrates in addition to the assessment of resected porcine intestinal tissue sections. Caco-2 cells and Caco-2/CCD-18co co-cultures grown on nanofibre substrates were found to have lower electrical resistance and higher permeability properties than their transwell equivalents. Caco-2/CCD-18co co-cultures on conventional transwell inserts demonstrated a permeability profile closer to the resected porcine tissue and reported human tissue values than the conventional Caco-2 model whilst maintaining p-glycoprotein assay sensitivity. This work forms a solid foundation for further research into the role of myofibroblasts in epithelial cell function and in the development of more predictive in vitro cell models for widespread scientific research.

A Confucian-Socratic framework provides a structure for analyzing culture-influenced aspects of academic learning. It is argued that these ancient exemplars model approaches to learning that continue to differentiate students within a modern Canadian postsecondary context. Specifically, it is argued that Chinese cultural influence increases the likelihood that a student will report Confucian learning beliefs and behaviors and that Western cultural influence increases the likelihood that a student will report Socratic learning beliefs and behaviors. Socrates valued private and public questioning of widely accepted knowledge and expected students to evaluate others' beliefs and to generate and consider their own hypotheses. Confucius valued effortful and pragmatic acquisition of essential knowledge. Confucius also valued poetic summary and behavioral reform. Two self-report studies, one (pilot) expert study, and one work sample study assess the utility of this framework in a Canadian context. The self-report studies provide evidence that the framework is reflective of modern cultural differences as expressed in a Western postsecondary context; however, the work sample study produced mainly null results. Consequences of cultural differences in Western postsecondary contexts are discussed. / Arts, Faculty of / Psychology, Department of / Graduate

The present study examined the perceptions of teams and managers on team potency levels as a function of stage of team development. Drawing from the power and influence literature, potency was established as a means by which to assess team's internal dynamics. Stage of team development was separated into four categories including pseudo, potential, real and high performance teams. Archival data included 45 teams and managers gathered from the manufacturing and service industries. Results indicated a significant linear relationship between team perceptions of team potency and stage of team development. Additionally, potency perceptions of teams significantly differentiated between the four stages of team development. Manager perceptions of team potency produced non-significant results. Possible explanations of the results as well as implications for practice and future research are provided.

The primary purpose of this research paper was to study performance anxiety among middle school students during a sight-reading audition. Furthermore, this sutdy asks whether the manner in which directions are presented by the sight-reading adjudicator during the course of an audition has significant impact on the performance outcome. Participants (n=75) were middle school students attending a highly rated band program in the Miami-Dade County (Miami, FL) area. By use of investigator-derived surveys, levels of trait and state anxiety were determined before and after the sight-reading performance. Means and standard deviations were calculated for perceived anxiety and for the resulting scores of the performance. A t-testcompared the control and experimental groups perceived level of anxiety, where statistically significant results were found at the pp

Within interstate militarized disputes, states use different kinds of influence strategies, like bullying, reciprocating, and trial-and-error. My dissertation examines state influence strategies within border disputes. This context serves as a hard test which could testify if state behaviors in world politics are mainly driven by the salience of contested issues. Or other factors, like leader militarized backgrounds (e.g., participating in rebellions or military service), may also at work. On the other hand, focusing on state influence strategies could be a promising direction to investigate the dynamics of border disputes, like border crisis outcomes. My dissertation contains three chapters. The first chapter explores the rationales behind state choices of influence strategies in border crises by focusing on leaders and their militarized experiences. The second chapter focuses on the influence strategy's short-term effect by examining how do hey influence border crisis outcomes? The third chapter examines the influence strategy's long-term impact by investigating how do they affect the durability of border claims? My dissertation has some important findings. First, leader militarized backgrounds influence state choices of influence strategies. Second, bullying strategies create escalations, which make border crises more likely to end in stalemate or decisive outcomes. By contrast, both reciprocating and trial-and-error ease the tension and make border crises more likely to end in compromises. Third, in the long term, the bullying strategies enable states to learn the costs of territorial fights, who then are willing to drop territorial claims. Neither reciprocating or trial-and-error strategies has this effect.
