Web-based Training and Teaching: A Frequency-based Approach

To those involved in teaching and training, the 80/20 rule is probably one of the most universal phenomenon, e.g., 80% of questions come from 20% of students and 80% of time spent is on 20% of subjects. This article describes our experience in designing and beginning to create a prototype web-based teaching and training (WBTT) program at the Franchise University (FranchiseU; The URL is http://www.bus.lsu.edu/franchise.). Our objectives include demonstrating how the concept of the 80/20 rule can be used to create a WBTT program satisfying the major requirements of education brokerages on the Internet. To illustrate how the program operates, we describe its organizational model

Franchise Business Development Model: Theoretical Considerations

Franchising is not a popular business development form in Lithuania. Only 0.02% of all Lithuanian companies use franchising for business development, while in most of the developed countries franchise is recognized as a convenient business expansion form. So, what factors determine such differences in the use of franchising? Analysis of related literature showed, that mainly researchers analyse some aspects of franchising, however there is no systematized analysis which covers all the main franchise development elements. Therefore, the aim of this article is to systematize franchise business development phases, main elements and factors, influencing this process and to propose a theoretical franchise system development model. Thus, theoretical considerations about the main phases and elements of franchise system development as well as advantages and disadvantages of the system are analysed in the article. These theoretical considerations are generalized in theoretical franchise system development model, which shows, that development of franchise business consists of particular steps, starting from favourable conditions for the system to emerge; intention and ability of franchisor to form franchise based on his business; the establishment and initial development of franchise system; and its further functioning. The article does not test the model and even does not discuss the operationalization of it. Operationalization of the model as well as empirical evidence is presented by the authors in the forthcoming articles

Does franchising create value? An analysis of the financial performance of US public restaurant firms

Author's OriginalIt is commonly believed that the franchising method of distribution provides strategic and operational benefits to the companies that adopt it. These benefits should result in superior financial performance as compared to that of firms that do not use franchising. Yet, the empirical evidence of the effects of franchising on financial performance is sparse and mixed. The purpose of this paper is to further examine the empirical evidence of the impact of franchising on a firm’s financial performance by using performance metrics (Economic Value Added and Market Value Added) that are extensively used in corporate finance. This study focuses on the US public restaurant sector. The results provide some evidence that franchising firms create more market and economic value than do non-franchising firms. A revised version of this paper has since been published in the International Journal of Hospitality and Tourism Administration.

The James Webb Space Telescope Mission

Twenty-six years ago a small committee report, building on earlier studies, expounded a compelling and poetic vision for the future of astronomy, calling for an infrared-optimized space telescope with an aperture of at least $4m$. With the support of their governments in the US, Europe, and Canada, 20,000 people realized that vision as the $6.5m$ James Webb Space Telescope. A generation of astronomers will celebrate their accomplishments for the life of the mission, potentially as long as 20 years, and beyond. This report and the scientific discoveries that follow are extended thank-you notes to the 20,000 team members. The telescope is working perfectly, with much better image quality than expected. In this and accompanying papers, we give a brief history, describe the observatory, outline its objectives and current observing program, and discuss the inventions and people who made it possible. We cite detailed reports on the design and the measured performance on orbit.Comment: Accepted by PASP for the special issue on The James Webb Space Telescope Overview, 29 pages, 4 figure

Daily Zeaxanthin Supplementation Prevents Atrophy of the Retinal Pigment Epithelium (RPE) in a Mouse Model of Mitochondrial Oxidative Stress

Oxidative damage is implicated in the pathogenesis of age-related macular degeneration (AMD). The dry form of AMD (geographic atrophy) is characterized by loss of RPE, photoreceptors, and macular pigments. The cumulative effects of oxidative stress impact mitochondrial function in RPE. In Sod2flox/floxVMD2-cre mice, the RPE specific deletion of Sod2, the gene for mitochondrial manganese superoxide dismutase (MnSOD), leads to elevated oxidative stress in retina and RPE, and causes changes in the RPE and underlying Bruch’s membrane that share some features of AMD. This study tested the hypothesis that zeaxanthin supplementation would reduce oxidative stress and preserve RPE structure and function in these mice. Zeaxanthin in retina/RPE/choroid and liver was quantified by LC/MS, retinal function and structure were evaluated by electroretinogram (ERG) and spectral domain optical coherence tomography (SD-OCT), and antioxidant gene expression was measured by RT-PCR. After one month of supplementation, zeaxanthin levels were 5-fold higher in the retina/RPE/choroid and 12-fold higher in liver than in unsupplemented control mice. After four months of supplementation, amplitudes of the ERG a-wave (function of rod photoreceptors) and b-wave (function of the inner retina) were not different in supplemented and control mice. In contrast, the c-wave amplitude (a measure of RPE function) was 28% higher in supplemented mice than in control mice. Higher RPE/choroid expression of antioxidant genes (Cat, Gstm1, Hmox1, Nqo1) and scaffolding protein Sqstm1 were found in supplemented mice than in unsupplemented controls. Reduced nitrotyrosine content in the RPE/choroid was demonstrated by ELISA. Preliminary assessment of retinal ultrastructure indicated that supplementation supported better preservation of RPE structure with more compact basal infoldings and intact mitochondria. We conclude that daily zeaxanthin supplementation protected RPE cells from mitochondrial oxidative stress associated with deficiency in the MnSOD and thereby improved RPE function early in the disease course
