Teaching In Cyberspace: The Faculty Perspective

Broader audiences of students are seeking alternative course delivery methods using electronic formats.  For this reason, business instructors are embracing web-based delivery modalities to accommodate the needs of such audiences.  This presentation is intended for instructors choosing to enter online learning environments.  It provides suggestions for student-friendly online course design, delivery and closure.  Student friendly online courses begin with mental thought processes that drive course objectives and learning outcomes in the preparation phase of course development.  The student friendly environment then transpires as a result of the instructor’s style during course delivery.  The online instructor then leaves the audience with a final impression through course closure activities.  With the final course details completed, the instructor reflects on areas of success and potential improvement to be applied to future courses

Prophylactic removal of third molars: a risk-benefit analysis

The treatment of impacted third molars that have neither symptoms nor disease is controversial. One school of thought is that these teeth should be extracted before they do become symptomatic and/or diseased. A second school of thought advocates retaining these teeth until such time when they show evidence of developing symptoms or disease. The purpose of this review is to present the reasoning behind the two opposing schools of thought. Studies involving both the risks and the benefits of extracting and retaining asymptomatic, disease-free third molars were examined. There are studies to support the proponents of each school of thought. Proponents of removal are of the belief that many asymptomatic and disease-free impacted third molars eventually do become symptomatic and/or diseased, and do so when the patient is older. The morbidity and incidence of complications common to the procedure increase with age, and therefore proponents of removal prefer that surgery be performed at a younger age when the complications are less likely to be as severe or permanent. Those in support of retaining and monitoring these teeth are of the opinion that the status of these asymptomatic and disease-free impacted third molars may never change and therefore never require surgical intervention. They believe the increased complication rate and morbidity experience by some of the older surgical patients do not justify the routine removal of all asymptomatic, disease-free impacted third molars at an early age. Both groups recognize that when surgical intervention is employed, complications such as pain, swelling, alveolar osteitis, periodontal problems, temporomandibular joint disorders, nerve involvement, sinus communication, and financial stress are not uncommon. Ultimately, the clinician must consider the information presented in this review, and combine it with his/her academic knowledge and personal clinical experience to inform the patient of the risks and benefits of both treatment options. That way, the clinician and the patient together can decide the strategy for management of an asymptomatic, disease-free third molar

A novel and alternative in vitro method using microwave to study the epithelial-stromal interactions

The goal of the present work was to obtain a simple and reproducible experimental model that would maintain the characteristics of the extracellular physiological environment of breast epithelial cells, both in factors as well as stromal structure, on which we could grow and evaluate changes of normal and tumor breast cells. 3T3-L1 pre-adipocytes (breast stromal cell model) were cultured and irradiated in a microwave oven at different times and potencies. In order to lose their proliferation ability, cells had to be irradiated twice at 650 Watts with a two-minute pulse each. The characteristics of the treated stromal support were analyzed for cell morphology, presence of DNA and proteins. We then evaluated on this support the effect on proliferation and migration of both normal and tumor - murine and human - breast epithelial cells. Both cell types increased their proliferation, while only tumor cells increased migration, thus improving their metastatic capacity. We believe this is a new and simple experimental method of studying epithelial-stromal cell interaction.Fil: Sacca, Paula Alejandra. Consejo Nacional de Investigaciones Científicas y Técnicas.

Analysis of Japanese Hotel Employees\u27 Job Satisfaction and Its Association with Annual Income and Other Socio-Economic Variables

Researcher conducted quantitative analyses of Japanese hotel employees\u27 job satisfaction and its association with the other variables such as actual annual salary, desired annual salary, age, gender, highest education, years in the industry, number of jobs switched, size of the hotel etc. While some of the descriptive statistics might indicate that overall mean score of the job satisfaction appears to be improving, the research revealed where the increased variances of satisfaction might have come from. Series of hypotheses testing based on the industry-generated questions were conducted. While there were substantial evidences to support some allegations, relatively huge variances often indicated that the reality around the job satisfaction would be more complicated than simple linear modeling can explain its variances

Hotel and Restaurant Entry-Level Job Competencies: Comparisons of Management and Worker Perceptions

This article presents the findings of a central Florida study of lodging and restaurant managers as well as entrylevel workers who were graduates of hospitality management programs. It provides a theoretical construct as a basis of the methodology employed. The article then reports the findings of perceptions of desired knowledge, skills and abilities, and attitudes associated with entry-level employees. It further compares desired levels of preparation for entry-level positions in the industry as reported by respondents of both groups. Finally, the authors present conclusions and implications for central Florida practitioners and educators

Alternative Degree Program for Hospitality Educators

Hospitality and tourism education programs are becoming increasingly popular, as is an increased demand for qualified faculty Tends suggest that an insufficient number of qualified candidates exist relative to the demand for new faculty appointments. The authors present a proposed model for newly developed doctoral programs in hospitality education and suggestions for administrators considering the development of terminal degree programs for hospitality educators

Towards easy program migration using language virtualization

International audienceMigrating programs between language versions is a daunting task. A developer writes a program in a particular version of a language and cannot foresee future language changes. In this article, we explore a solution to gradual program migration based on virtualization at the programming language level. Our language virtualization approach adds a backwards-compatibility layer on top of a recent language version, allowing developers to load and run old programs on the more recent infrastructure. Developers are then able to migrate the program to the new language version or are able to run it as it is. Our virtualization technique is based on a dynamic module implementation and code intercession techniques. Migrated and non-migrated parts co-exist in the meantime allowing an incremental migration procedure. We validate it by migrating legacy Pharo programs, MuTalk and Fuel

Role of wnt/beta-catenin signaling in ovarian tumour growth and angiogenesis. A crosstalk with Notch system

Wnt/β-catenin and Notch are highly conserved pathways that regulate a diversity of cell processes, including proliferation, apoptosis and differentiation. We analyzed the role of both systems in ovarian cancer using specific inhibitors. For this purpose we performed three in vivo experiments. A human ovarian adenocarcinoma cell line (IGROV-1) was subcutaneously injected in 6-8 weeks-old female nude mice. Once the tumours were palpable, we injected the inhibitors: the first and second experiments were carried out using Wnt/β-catenin inhibitors (XAV939: 2.5, 5 mg/kg; ICG-001: 5 and10 mg/kg). The third experiment was a combination of ICG-001 (5mg/kg) and DAPT (5 mg/kg), a Notch inhibitor. Mice were injected every two days three times and they were euthanized 3 days after the last injection. Our results showed a significant decrease in tumour size when mice were treated either with XAV939 or with ICG-001. When compared with tumours from non-treated animals, both experiments showed a significant decrease in cell proliferation (KI67) and a decrease in the endothelial and periendothelial cell area stained with CD31 and α-Smooth-muscle-actin, respectively. When mice were treated with XAV939, a significant decrease in VEGF levels and Angiopoietin 1/2 was observed. Regarding the experiment with the combination of inhibitors, there was a significant decrease in tumour size and a decline in tumour cell proliferation (KI67). Both inhibitors administered simultaneously produced a decrease in cell proliferation at the same extent as individually administrated. In conclusion, we demonstrate a clear involvement of Wnt/β-catenin in ovarian tumour growth and angiognesis. We suggest an interaction of this pathway with Notch system.Fil: Bocchicchio, Sebastian.

Collapsing Stakeholder Groups: Insights Into Professional Sports Organizations And Competitive Positioning

The article investigates the force field stakeholder structure of National Football League (NFL) sport organizations relative to those that provide the domain that governs the management of other medium to large commercial entities. Textual and visual images of the affiliations among the various NFL organizations’ stakeholder groups in the manuscript provide a framework of the stakeholder force field domain. The model presents comparative and contrasting data relevant to typical business organizations of similar size, expenses, and revenue capacity. Finally, the article identifies managerial practices in NFL organizations and provides explanations for these processes applicable to the force field domain under which they are governed. The authors conclude that managerial practices in NFL organizations are contrary to those adhered to in regular commercial enterprises; however, these managerial practices are appropriate for the particular stakeholder force field domain that governs these particular sport organizations, which fosters “collaborative parity.” Future research that delves into areas of major league football’s and other leagues’ evolving economic constructs as they pertain to stakeholder issues such as controlling labor costs, the relocation of a particular team, and the necessity of increasing the volume of existing and emerging revenue streams is recommended
