Edge even graceful labelling of new families of graphs
No full textElsonbaty and Daoud introduced a new type of labelling of a graph G with p vertices and q edges called an edge even graceful labelling. A graph G is called edge even graceful if there is a bijection such that, when each vertex is assigned the sum of all edges incident to it mod , where , the resulting vertex labels are distinct. In this paper we proved that double fan graphs, quadrilateral friendship graphs, and butterfly graphs are edge even graceful graphs
Edge Even Graceful Labeling of Polar Grid Graphs
No full textEdge Even Graceful Labelingwas first defined byElsonbaty and Daoud in 2017. An edge even graceful labeling of a simple graph G with p vertices and q edges is a bijection f from the edges of the graph to the set { 2 , 4 , … , 2 q } such that, when each vertex is assigned the sum of all edges incident to it mod 2 r where r = max { p , q } , the resulting vertex labels are distinct. In this paper we proved necessary and sufficient conditions for the polar grid graph to be edge even graceful graph
Edge even graceful labelling of some book graphs
No full textElsonbaty and Daoud introduced a new type of labelling of a graph G with p vertices and q edges called an edge even graceful labelling if there is a bijection f from the edges of the graph to the set such that, when each vertex is assigned the sum of all edges incident to it mod , where , the resulting vertex labels are distinct. They proved necessary and sufficient conditions for some path and cycle-related graphs to be edge even graceful. In this paper we proved that triangular book graphs and quadrilateral book graphs admit edge even graceful labelling
EFL/ESP teacher development and classroom innovation through teacher-initiated action research
No full textThis study is an investigation of the potential of teacher-initiated action research for
EFL/ESP teacher development and classroom innovation. The Collaborative Academic
Writing Research Project (CAWRP), on which it is based, was carried out at the ESP
Centre, Damascus University, in 1996-1997. It was in two phases, Baseline and
Main. The researcher, a teacher in the context, assumed a participatory and facilitating
role. The pedagogic problem was the teaching of research paper writing to
postgraduate students. The CAWRP was proposed to ease this problem and introduce
classroom innovation through teacher-initiated action research, the long-term aim of
which was continuous professional development. The baseline research aimed at
articulating a picture of teacher and context needs and assessing project viability. The
proposal was refined in the light of the findings, and a programme of teacher
development activities was agreed with the participants. This was implemented in the
Main Phase, which had three stages: Orientation, Research and Reporting, and
Summative Evaluation and Follow-up. The role of the researcher was to facilitate the
teachers to self-direct their professional learning and introduce needed pedagogic
innovations.
The thesis is in eight chapters and 32 appendices. Chapter One sets the scene
and introduces the study. Chapter Two focuses on the baseline investigation: its
methodology, findings, and their implications for the Main Phase study. Chapter Three
is a review of the relevant literature in the fields of teacher development and classroom
innovation. Chapter Four focuses on project design and methodology and gives more
details on the principles, values, strategies, and procedures that guided project
implementation and how they worked out in action. Chapter Five reports the findings,
focusing on the contribution of the Orientation Stage activities to the development of
the teacher group as a whole (a total of 20 out of 23 Centre teachers). Its main sources
of data are recordings, feedback questionnaires, and participant observation. Chapter
Six focuses on the teachers who carried out action research and reported on it (8 out
of the 20 Orientation Stage participants). It presents two case studies of frill
participants, starting with their entry points and showing how they developed in the
Research and Reporting Stage. One case exemplifies the experienced teachers and
those who did research individually, and the other the novices and those who worked in
collaboration. Chapter Seven reports on the participants' sununative evaluation of the
project and the effect of this evaluation on project continuity. Chapter Eight
summarises the main findings and evaluates them with reference to the literature, on
the one hand, and design principles and methodology, on the other. In this chapter, I
have looked critically at the lessons learnt from the study, discussed its significance and
limitations, and put forward some recommendations. The appendices include some of
the materials and documentary evidence used in the research

Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods

The Right to Strike under the United States Constitution: Theory, Practice, and Possible Implications for Canada
No full textAnswering critics of the Canadian Supreme Court's judgment in B.C. Health, the author argues that the Court laid the foundation for a principled and durable doctrine protecting constitutional labour rights, one that goes directly to the heart of the matter — the inequality of workers’ power in the employment relation. In the author’s view, two paths could lead from B.C. Health to the recognition of Charter protec- tion for a right to strike: one that treats the right as an accessory to col- lective bargaining, and one that upholds the right directly on the basis of the Charter values of equality and participation. The author supports the latter approach, contending that constitutional rights should be defined in relation to fundamental values, in a way that is not contingent on time-bound or fact-sensitive assessments about the role of strikes within a particular collective bargaining regime. Although a Charter right to strike may involve the courts in difficult choices about when to defer to legislative policy decisions, and courts may lack the institutional capac- ity to deal effectively with labour law issues, the author points out that judges can look to ILO standards for expert guidance. Noting that the U.S. experience in this area might be of considerable use to Canadians, the author concludes by providing an overview of American case law concerning a constitutional right to strike.Peer reviewe
A Narrativa como espaço de construção de identidades raciais e tradutórias: o caso de O Tradutor : memórias de um homem que desafiou a guerra de Daoud Hari
No full textDissertação (mestrado) - Universidade Federal de Santa Catarina, Centro de Comunicação e Expressão, Programa de Pós-Graduação em Estudos da Tradução, Florianópolis, 2011Esta dissertação analisou a relação entre narrativa, identidades e tradução na obra O Tradutor: memórias de um homem que desafiou a guerra de Daoud Hari. A hipótese que norteou o estudo sugere que os fenômenos da narrativa pós-colonial, juntamente com valores culturais africanos e ocidentais, estão na origem geradora das identidades do narrador e providenciam o conteúdo linguístico/cultural para o estudo da tradução. Os objetivos estabeleceram quatro tipos específicos de análise: (1) as semelhanças e diferenças culturais que relacionam os mundos Africano e Ocidental; (2) as identidades nacionalista, assimilacionista e catalista do narrador; (3) as associações entre essas modalidades de identidades e as categorias de narrativas ontológicas e públicas presentes no O Tradutor; e (4) os fenômenos culturais que distinguem texto-fonte e texto-alvo. A metodologia estipulou quatro capítulos: o primeiro discutiu as modalidades narrativas ontológica e pública, com base nos escritos de Baker (2006) sobre o assunto; o segundo relacionou o pós-colonialismo à caracterização das identidades, buscando em Hall (2006) o suporte teórico; o terceiro se valeu de Chesterman (1997), para construir uma visão de tradução como meme; o quarto e último capítulo, tomou excertos de O tradutor para construir relações entre narratividade, identidade e tradução. Para a análise comparativa do texto de origem e destino, 30 excertos da obra O Tradutor foram selecionados - quinze ontológicos e quinze públicos. Os resultados mostraram diferenças entre as narrativas ontológicas e públicas: a primeira se concentrou na vida pessoal do narrador/tradutor Hari; a segunda, nas experiências coletivas do povo sudanês. Os resultados também revelaram distinções identitárias: através da assimilação, Hari se aproximou dos valores culturais do Ocidente: a língua Inglês/Europeu, literatura e tecnologia; por meio do nacionalismo Hari enfatizou o seu apego aos valores culturais africanos como, por exemplo, a família, o idioma nativo zaghawa, e o povo sudanês que enfrentava o genocídio; com o catalismo, soube fundir os valores ocidentais e africanos, simbolizados pela tradução interlingual entre o idioma zaghawa e o inglês. O uso de estratégias de tradução pelo tradutor brasileiro Moura Filho demonstrou que as diferenças entre os idiomas de origem e de destino derivaram da aplicação das estratégias sintáticas, semânticas e pragmáticas. As conclusões realçaram a validade da aproximação da tradução à narratividade e à construção de identidade, em um ambiente marcado pelo tipo de perspectiva pós-colonial que examina a coexistência de elementos ou fenômenos culturais de africanos e ocidentais em narrativas de autores africanos
