Alumni involvement in a technology program

Abstract: Everyone knows that in today's modern world, it is hard to keep up with the pace of the ever changing field of technology. This is no different in technology programs at the cegep level. Teachers who are employed at the cegep level find it difficult to keep up to date with the evolving industry trends, especially when working full time. In this paper, the involvement of alumni in the program is examined. The purpose of this study is to examine five areas of alumni involvement. These five major areas of alumni involvement are advisory committees, internships, field trips, guest speaking and real life projects. The literature is reviewed with respect to each of the described areas of involvement as well as theories of motivation. The shift of emphasis from teacher to student is discussed as well as the role of the teacher when faced with changes in technology. Finally students and alumni are surveyed to examine their perceptions to the various types of alumni involvement in the B.S.E.T. program. This research helps to describe whether and to what degree alumni involvement benefits our students in B.S.E.T. Several variables are examined, such as: academic satisfaction and alumni involvement; graduation year and academic satisfaction; graduation year and alumni involvement. The study also examines areas such as motivational attitudes of graduates to stay involved; areas where it is crucial for alumni to stay involved; desire to partner in a capstone project and area of involvement that tends to motivate students the most and that the graduates find of utmost importance.

Host-guest complexation of a nitroheterocyclic compound with cyclodextrins: a spectrofluorimetric and molecular modeling study

Nitroheterocyclic compounds (NC) were candidate drugs proposed for Chagas disease chemotherapy. In this study, we investigated the complexation of hydroxymethylnitrofurazone (NFOH), a potential antichagasic compound, with alpha-cyclodextrin (alpha-CD), beta-cyclodextrin (beta-CD), Hydroxypropyl-beta-cyclodextrin (HP-beta-CD), Dimethyl-beta-cyclodextrin (DM-beta-CD) and gamma-cyclodextrin (gamma-CD) by fluorescence spectroscopy and molecular modeling studies. Hildebrand-Benesi equation was used to calculate the formation constants of NFOH with cyclodextrins based on the fluorescence differences in the CDs solution. The complexing capacity of NFOH with different CDs was compared through the results of association constant according to the following order: DM-beta-CD > beta-CD > alpha-CD > HP-beta-CD > gamma-CD. Molecular modeling studies give support for the experimental assignments, in favor of the formation of an inclusion complex between cyclodextrins with NFOH. This is an important study to investigate the effects of different kinds of cyclodextrins on the inclusion complex formation with NFOH and to better characterize a potential formulations to be used as therapeutic options for the oral treatment of Chagas disease.

Special issue: Selected papers from the sixth IFIP 2.6 working conference on visual database systems: Guest editors' introduction

While multimedia data, image data in particular, is an integral part of most websites and web documents, our quest for information so far is still restricted to text based search. To explore the World Wide Web more effectively, especially its rich repository of truly multimedia information, we are facing a number of challenging problems. Firstly, we face the ambiguous and highly subjective nature of defining image semantics and similarity. Secondly, multimedia data could come from highly diversified sources, as a result of automatic image capturing and generation processes. Finally, multimedia information exists in decentralised sources over the Web, making it difficult to use conventional content-based image retrieval (CBIR) techniques for effective and efficient search. In this special issue, we present a collection of five papers on visual and multimedia information management and retrieval topics, addressing some aspects of these challenges. These papers have been selected from the conference proceedings (Kluwer Academic Publishers, ISBN: 1-4020- 7060-8) of the Sixth IFIP 2.6 Working Conference on Visual Database Systems (VDB6), held in Brisbane, Australia, on 29–31 May 2002.

An evaluation of active lecturing in a computer networks course

The article describes an attempt to improve student learning outcomes in a computer networks course by making lectures more active learning experiences. Quick quizzes, group and individual exercises, the review of student questions, as well as multiple breaks, were incorporated into the weekly three-hour lectures. Student responses to the modified lectures was overwhelmingly positive: over 85% of respondents agreed that the lectures aided understanding, with large majorities of the respondents finding the individual activities useful to their learning. Although student examination performance improved over the previous year, performance on an examination question that was designed to examine deep understanding remained unchanged.

As relações públicas para além das guest relations: relatório de estágio no grupo Porto Bay Hotels & Resorts

Foi realizado um estágio no grupo Porto Bay Hotels & Resorts, um grupo hoteleiro da Região Autónoma da Madeira, com a duração de três meses. Apresenta-se assim no presente trabalho uma perspectiva das Relações Públicas no sector do turismo e hotelaria bem como a discussão do porquê do afunilamento desta função de gestão das relações entre as organizações e os seus públicos nas Guest Relations em algumas das unidades hoteleiras em que trabalhámos. O turismo é actualmente um dos principais sectores da economia mundial. A sobrevivência de um destino turístico, unidade hoteleira ou mesmo de um resort, depende em muito da percepção que os seus stakeholders têm da qualidade dos seus serviços. Assim as Relações Públicas, como em outros sectores, assumem um papel de destaque sendo que estas têm a capacidade de trabalhar a relação entre uma organização e os seus stakeholders, gerindo conflitos e expressando uma identidade positiva sobre a mesma e trabalhando a sua reputação e visibilidade. Em suma este trabalho pretende compreender e reflectir sobre as relações públicas no sector do turismo e hotelaria mesmo quando não o são assim entendidas. Defender-se-á uma perspectiva global, integrada e proactiva das Relações Públicas no sector hoteleiro.

Guest editorial: OPTIMAX 2013

In 2012 we were awarded an Erasmus Intensive Programme grant to facilitate OPTIMAX 2013, a three week duration residential summer school held within the UK during August 2013. The summer school helped to further develop student radiographer skills in optimising x-radiation dose and image quality. With a major emphasis on visual techniques to determine image quality, lesion visibility, lesion detection performance and physical measures of image quality (eg signal to noise ratio (SNR)) we conducted controlled laboratory experiments on phantoms using Computed Radiography, CT and Full Field Digital Mammography. Mathematical modelling was used for radiation dose estimation. Sixty seven people from 5 European countries participated. This included 49 PhD, MSc and BSc students. Discipline areas included radiography, physics, biomedical science and nuclear medicine.

Host-Guest interaction between herbicide oxadiargyl and hydroxypropyl-β-cyclodextrin

In the face of a growing human population and increased urbanization, the demand for pesticides will simply rise. Farmers must escalate yields on increasingly fewer farm acres. However, the risks of pesticides, whether real or perceived, may force changes in the way these chemicals are used. Scientists are working toward pest control plans that are environmentally sound, effective, and profitable. In this context the development of new pesticide formulations which may improve application effectiveness, safety, handling, and storage can be pointed out as a solution. As a contribution to the area, the microencapsulation of the herbicide oxadiargyl (OXA) in (2-hydroxypropyl)-β-cyclodextrin (HP-β-CD) was performed. The study was conducted in different aqueous media (ultrapure water and in different pH buffer solutions). In all cases an increment of the oxadiargyl solubility as a function of the HP-β-CD concentration that has been related to the formation of an inclusion complex was verified. UV-Vis and NMR experiments allowed concluding that the stoichiometry of the OXA/HP-β-CD complex formed is 1 : 1. The gathered results can be regarded as an important step for its removal from industrial effluents and/or to increase the stabilizing action, encapsulation, and adsorption in water treatment plants.
