Reputation versus reality: the impact of US News and World Report rankings and education branding on hiring decisions in the job market
Typically, leading brands provide benchmarks for constructing consumer preference in the marketplace. Reputation rankings have sustained and advanced the status of brand names in higher education with an implication that the degrees awarded by higher ranked schools have added prestige, a cachet with the potential of facilitating success in the job market. This implication makes reputation rankings a dependable tool for college and university marketing departments eager to increase student enrollment and retention by communicating its superiority among its peers. By examining the influence of reputation rankings on the pre-decision preferences of human resource hiring professionals in evaluating employment applicants, this study found that there is little if any relationship between a degree from a higher education institution in the top tier of a reputation ranking and employment acquisition. Work experience emerged as the major deciding factor in the assessment of an applicant\u27s qualifications. Degree field and employee referral appeared as important matters, while education program and academic record followed in playing a slightly diminished role. Academic record and non academic activities had a lesser degree of influence on hiring decisions. Future study into the subconscious and conscious effect of reputation rankings on the job attainment goal of a college student in relation to the student\u27s choice of HEI could provide new insights into student choice, college marketing strategy, and the value of rankings in education
Marcatili's Lossless Tapers and Bends: an Apparent Paradox and its Solution
Numerical results based on an extended BPM algorithm indicate that, in
Marcatili's lossless tapers and bends, through-flowing waves are drastically
different from standing waves. The source of this surprising behavior is
inherent in Maxwell's equations. Indeed, if the magnetic field is correctly
derived from the electric one, and the Poynting vector is calculated, then the
analytical results are reconciled with the numerical ones. Similar
considerations are shown to apply to Gaussian beams in free space.Comment: 4 pages, figures include
Humanization through Action Research as Methodology
The purpose of this action research study was to critically examine the use of action research as a mechanism to enhance graduate students’ development as emerging qualitative researchers. Although action research has been recognized as an effective means of transforming teaching practices, studies examining its use among graduate students learning to become qualitative researchers are lacking. Participants profiled in this study include two graduate students and one teacher educator. The context of the study was a graduate level course on action research where all three participants identified starting points, employed distinct action strategies, engaged in sustained, critical reflection, and developed metaphors representing their living educational theories of their practice. Results from this study indicate that each participant gained a deeper self-awareness and understanding of enacting qualitative research and furthermore, recognized action research as a powerful humanizing agent
Low-Temperature-Induced Controllable Transversal Shell Growth of NaLnF4 Nanocrystals
Highly controllable anisotropic shell growth is essential for further engineering the function and properties of lanthanide-doped luminescence nanocrystals, especially in some of the advanced applications such as multi-mode bioimaging, security coding and three-dimensional (3D) display. However, the understanding of the transversal shell growth mechanism is still limited today, because the shell growth direction is impacted by multiple complex factors, such as the anisotropy of surface ligand-binding energy, anisotropic core–shell lattice mismatch, the size of cores and varied shell crystalline stability. Herein, we report a highly controlled transversal shell growth method for hexagonal sodium rare-earth tetrafluoride (β-NaLnF4) nanocrystals. Exploiting the relationship between reaction temperature and shell growth direction, we found that the shell growth direction could be tuned from longitudinal to transversal by decreasing the reaction temperature from 310 °C to 280 °C. In addition to the reaction temperature, we also discussed the roles of other factors in the transversal shell growth of nanocrystals. A suitable core size and a relative lower shell precursor concentration could promote transversal shell growth, although different shell hosts played a minor role in changing the shell growth direction
Frequency addressing of nano-objects by electrical tuning of optical antennas
We first analyze the equivalent circuit parameters of linear wire optical nano-antennas in uniaxial anisotropic media. We then exploit the electro-optic response of a bipolar nematic liquid crystal to demonstrate tuning of an optical antenna using a low frequency external electric field as the control mechanism
New Technologies for Ecosystem Analysis Planning and Management
Planning the rural environment is one of the most intriguing examples of technical challenge where a multi-disciplinary approach plays a crucial role. The agricultural production, both food and non-food, the social role of rural settlements, the state and diffusion of the infrastructural networks, the rural architectonic heritage that in many countries constitutes a major positive value, should be appropriately considered and sinergically interlaced for a sound planning of agricultural biosystems.
Human activities impose a transformation of the extra-urban land that may lead to the modification of the frail equilibrium of whole ecosystems. Sound planning strategies should be therefore pursued, employing a multidisciplinary approach that should take into account geographical, environmental and landscape factors as variables interacting among themselves and with the social and economic aspects. In order to simultaneously analyse all these properties, tools able to manage, interpret and integrate several data are necessary

Transepithelial Corneal Cross-Linking With Vitamin E-Enhanced Riboflavin Solution and Abbreviated, Low-Dose UV-A: 24-Month Clinical Outcomes
Purpose: To report the clinical outcomes with 24-month follow-up of transepithelial cross-linking using a combination of a D-alpha-tocopheryl polyethylene-glycol 1000 succinate (vitamin E-TPGS)-enhanced riboflavin solution and abbreviated low fluence UV-A treatment.
Methods: In a nonrandomized clinical trial, 25 corneas of 19 patients with topographically proven, progressive, mild to moderate keratoconus over the previous 6 months were cross-linked, and all patients were examined at 1, 3, 6, 12, and 24 months. The treatments were performed using a patented solution of riboflavin and vitamin E-TPGS, topically applied for 15 minutes, followed by two 5-minute UV-A treatments with separate doses both at fluence below 3 mW/cm2 that were based on preoperative central pachymetry.
Results: During the 6-month pretreatment observation, the average Kmax increased by +1.99 +/- 0.29 D (diopter). Postoperatively, the average Kmax decreased, changing by -0.55 +/- 0.94 D, by -0.88 +/- 1.02 D and by -1.01 +/- 1.22 D at 6, 12, and 24 months. Postoperatively, Kmax decreased in 19, 20, and 20 of the 25 eyes at 6 months, 12 months, and 24 months, respectively. Refractive cylinder was decreased by 3 months postoperatively and afterward, changing by -1.35 +/- 0.69 D at 24 months. Best spectacle-corrected visual acuity (BSCVA) improved at 6, 12, and 24 months, including an improvement of -0.19 +/- 0.13 logarithm of the minimum angle of resolution units at 24 months. There was no reduction in endothelial cell count. No corneal abrasions occurred, and no bandage contact lenses or prescription analgesics were used during postoperative recovery.
Conclusions: Transepithelial cross-linking using the riboflavin-vitamin E solution and brief, low-dose, pachymetry-dependent UV-A treatment safely stopped keratoconus progression
Autologous Hematopoietic Stem Cell Transplantation (AHSCT): Standard of Care for Relapsing–Remitting Multiple Sclerosis Patients
Abstract Autologous hematopoietic stem cell transplantation (AHSCT) has been used in the treatment of highly active multiple sclerosis (MS) for over two decades. It has been demonstrated to be highly efficacious in relapsing–remitting (RR) MS patients failing to respond to disease-modifying drugs (DMDs). AHSCT guarantees higher rates of no evidence of disease activity (NEDA) than those achieved with any other DMDs, but it is also associated with greater short-term risks which have limited its use. In the 2019 updated EBMT and ASBMT guidelines, which review the clinical evidence of AHSCT in MS, AHSCT indication for highly active RRMS has changed from “clinical option” to “standard of care”. On this basis, AHSCT must be proposed on equal footing with second-line DMDs to patients with highly active RRMS, instead of being considered as a last resort after failure of all available treatments. The decision-making process requires a close collaboration between transplant hematologists and neurologists and a full discussion of risk–benefit of AHSCT and alternative treatments. In this context, we propose a standardized protocol for decision-making and informed consent process
