Graduate students in the College of Education at the University of North Texas, Denton rated 57 teacher attributes on their relative importance in effective teaching. The data was analyzed across six demographic variables of department, sex, degree, nationality, teaching experience, and previous graduate school, using mean scores, one-way ANOVA, and t-tests for two independent samples.

A vertex υ in a set S is said to be cost effective if it is adjacent to at least as many vertices in V\S as it is in S and is very cost effective if it is adjacent to more vertices in V\S than to vertices in S. A dominating set S is (very) cost effective if every vertex in S is (very) cost effective. The minimum cardinality of a (very) cost effective dominating set of G is the (very) cost effective domination number of G. Our main results include a quadratic upper bound on the very cost effective domination number of a graph in terms of its domination number. The proof of this result gives a linear upper bound for hereditarily sparse graphs which include trees. We show that no such linear bound exists for graphs in general, even when restricted to bipartite graphs. Further, we characterize the extremal trees attaining the bound. Noting that the very cost effective domination number is bounded below by the domination number, we show that every value of the very cost effective domination number between these lower and upper bounds for trees is realizable. Similar results are given for the cost effective domination number.

For a graph G=(V, E) and a set of vertices S⊆ V, a vertex v∈S is said to be very cost effective if it is adjacent to more vertices in V{set minus}. S than in S. A bipartition π= {S, V{set minus}. S} is called very cost effective if both S and V{set minus}. S are very cost effective sets. Not all graphs have a very cost effective bipartition, for example, the complete graphs of odd order do not. We characterize the cactus graphs having a very cost effective bipartition. Also, we show that if a graph G or H has a very cost effective bipartition, then so does the Cartesian product G□ H.

This thesis reports a study of a group of Iranian young learners, their parents and language teachers on their perceptions of the characteristics of effective language teachers in public schools. The research methodology adopted was a mixed method and therefore, the first part of the study was conducted through a questionnaire survey of 190 students studying in the 8th grade of public schools in Iran. This was followed by interviews with a sample of these learners, their parents and their teachers. The data emerging from the study demonstrates that the stakeholders involved in this study hold perceptions across a wide range of areas concerning language teacher effectiveness including teachers’ language proficiency, class management and affective factors. There was some general agreement within and among the stakeholders’ views; however, at times the dimensions slightly varied. On the whole, the main concerns were related to teachers’ knowledge and ability to speak English and teachers’ willingness to insert activities beyond the prescribed syllabus in particular activities related to speaking skill, and also additional activities that would prepare the students for their exams. Teachers’ ability to build the right rapport with the students was also very much in demand. An unanticipated finding of this study was the perceived connection between teachers’ appearance and in particular the way they dressed and their effectiveness. Some discrepancies relating to how these should be actually practised in the class do exist. Finally, this thesis goes on to discuss some of the implications of these findings both for English language teaching in Iran and for future research. Although the findings of this study are not conclusive and not prescriptive, they reveal the importance of exploring the views of stakeholders to make language teaching a more pleasant experience for all, which can in turn lead to a more effective teaching and learning.

The purpose of this paper is to investigate how investments in trade shows can be made more effective. The method was a descriptive study build on primary and secondary sources. The primary sources were collected in an anonymous survey where 204 respondents were asked about their experience of trade shows and what attracts them. The secondary sources were collected from previous research collected from scientific articles. The theory indicated that more effective investments in trade shows could be made upon what the visitor requires and attracts of. The implication of the paper was that inspiration is the primary factor to visit trade shows and that a spectacular stand and dedicated and inviting people in the stand are the factors that attract the visitors. Therefor exhibitors ought to prioritise their resources to improve these factors. Another significant factor is to develop the company´s Internet approach in a strategic way pre- and post-show. Above all, that the exhibitor chooses trade shows within their industry.

Paddlefish (Polyodon spathula) is a commercially and recreationally important species, with a native range that extends over 22 US states. This is a large, long-lived, highly mobile riverine species that has been negatively impacted by habitat fragmentation, historic overharvest, and hatchery supplementation. Dams are the primary cause of habitat fragmentation, blocking migration routes, flooding spawning grounds, and isolating populations. A common management action to mitigate the impacts of habitat fragmentation and maintain harvestable populations is hatchery propagation and stocking. Reduction in stock size, isolation of populations, and stocking can all negatively impact the genetic integrity of Paddlefish. I evaluated the impacts of isolation and hatchery supplementation on the effective population size (Ne) of Paddlefish as well as the range-wide genetic structure of Paddlefish.

Therefor exhibitors ought to prioritise their resources to improve these factors. Plans and targets are important tools to following up the outputs from trade shows. It is also about making a consideration of focus between visitors that already have interest and the visitors that just looking. The exhibitors have to think about if they value profits in short or/and in long run. The consideration is also about how they handling giveaways and gift in the most effective way. Another significant factor is to develop the company´s Internet approach in a strategic way pre- and post-show. Above all, that the exhibitor chooses trade shows within their industry.

Batu velakero iri kenaga, loboro mana vakatikili gira vano muzi (Highly effective leaders are at the front, walk in the middle, and encourage those from behind to catch up) My uncle Zorapa said, while I was on a 'pig-hunting' trip with him some twenty odd years ago, that school principals, like all leaders, can only be called leaders if they make a difference. In modern parlance, one frequently encounters this homespun wisdom in the statement that highly effective schools are led by highly effective principals. This study investigates the perceptions of six practicing principals of the elements of highly effective principalship in Solomon Islands' Community High schools. The study investigates and explores these perceptions and tries to describe the elements of highly effective principalship and the impediments that may prevent principals from becoming effective. The study hopes to contribute towards the possible development of highly effective principalship in the Solomon Islands schools. The finding of this research reveals that although the participating principals were very experienced, their responses indicate that there appeared to be no theory-driven basis for their practice. Similarly, the perceptions expressed reveal the urgent need for the Solomon Islands to pay more attention to leadership development strategies that will see the creation of national, and personal, leadership philosophies and set the process of ongoing leadership development, enhancement and improvement in the country. The proposed strategies must incorporate current international research and literature on educational leadership theories as well as building on current practice in the Solomon Islands that is nationally and culturally appropriate. In addition, the study suggests that current practitioners should be encouraged to engage in educational leadership research and begin to build a national literature base. This study suggests that the process of establishing the notion of highly effective educational leadership in the country's school system should start as soon as possible. Those in policy and decision-making positions must have the courage to implement strategies that will contribute to improved levels of educational leadership in order to raise the quality of education for all learners in the country. The children are the future prosperity of the country.
