An Emotionally Intelligent Industry? Assessing the Emotional Intelligence of Hospitality Employees and Students

The aim of this paper is to assess whether there are any differences in the emotional intelligence of hospitality employees and students compared to those employed in or studying to enter other industries. Emotional intelligence has received considerable attention in recent years and has been purported by some authors to be the “magic ingredient” which leads to superior performance. This article begins by broadly defining emotional intelligence and discusses the general debate surrounding the conceptualisation, definition and operationalisation of this construct. It then proceeds to use an established, objective, performance based measure of Emotional Intelligence (the MSCEIT) on a self selected sample of 184 respondents. The sample included hospitality practitioners and students as well as practitioners and students from other industries. The emotional intelligence of the groups within the sample was compared in terms of; gender, industry, age, and occupation. Finally, the emotional intelligence of this sample was compared to that of a normed, North American sample. The results, which suggest that a combination of maturity and industry experience contribute most to the development of emotional intelligence, are evaluated in light of their implications for the hospitality industry and hospitality education.
Dopa‐responsive parkinsonism phenotype of spinocerebellar ataxia type 2

We report on 2 brothers, Patients 1 and 2, who presented with a similar clinical syndrome consisting of resting tumor, bradykinesia, rigidity, and dysarthria at the ages of 40 and 43 years, respectively. An excellent response to levodopa therapy was observed throughout the disease course. No gait or limb ataxia, slow saccades, or decreased tendon reflexes were detected, but unsteadiness of gait with propulsion developed recently in Patient 1 approximately 25 years after disease onset. Magnetic resonance imaging demonstrated mild atrophy of the pons and cerebellum in Patient 1 and cerebellar atrophy in Patient 2. Expanded CAG repeats, numbering 36, in one allele of the ataxin‐2 gene were identified in Patient 1 only; his brother was not available for this investigation. With [99mTc]TRODAT‐1 single photon emission computed tomography of the brain, a significant bilateral and asymmetrical reduction of striatal dopamine transporters was found in Patient 1 compared to healthy controls. This bilateral reduction of striatal dopamine transporters resembled that observed in a set of controls with Parkinson's disease who had asymmetrical impairment. These results suggest that patients with familial parkinsonism who present with typical Parkinson's disease should be screened for the genetic defect of spinocerebellar ataxia type 2. The presynaptic impairment of nigrostriatal function is very likely to be the reason for levodopa responsiveness. © 2002 Movement Disorder Society
A Grey-Level Image Embedding its Color Palette

In this paper, we propose a method to embed the color information of an image in its corresponding grey-level image. The objective of this work is to allow free access to the grey-level image and give color image access to secret key owners. This method is made of two steps which are the color image decomposition (in a grey-level image and its associated color information) and the data-hiding. The main contribution of this paper is the energetic function proposed to model the decomposition of the color image. The optimization of the proposed energetic function leads to the obtention of an index image and a color palette. The good properties of that decomposition are an index image which is similar to the luminance of the color image and a color palette which is well suit for the data-hiding. The obtained results confirm the model quality.
Isolation of Aeromonas hydrophila from a metropolitan water supply: seasonal correlation with clinical isolates

The occurrence of Aeromonas spp. in the metropolitan water supply of Perth, Western Australia, Australia, was monitored at several sampling points during a period of 1 year. Water within the distribution system conformed to international standards for drinking water but contained Aeromonas spp. in numbers comparable to those in raw surface water, although this water was free of Escherichia coli. Coliforms and E. coli were found in raw surface waters, and Aeromonas spp. were found in raw water from surface and underground sources. Chemical treatment, followed by chlorination at service reservoirs, resulted in water free of E. coli and a decrease in the number of Aeromonas spp. Aeromonas spp. were found in the greatest numbers in summer. Multiple regression analysis showed that growth of Aeromonas spp. in chlorinated water was related to water temperature, residual chlorine, and interaction between these variables. The incidence of Aeromonas-associated gastroenteritis, determined from isolates referred to us for enterotoxin testing, paralleled the pattern of isolation of Aeromonas spp. in water within the distribution systems. We suggest that the presence of Aeromonas spp. in drinking water needs public health appraisal and that further work should be undertaken to permit reevaluation of standards for the quality of drinking water.
Mobilité et grande pauvreté

Dans un contexte de croissance des disparites sociales et spatiales, la question de l'accessibilite de tous a la ville et a ses services est posee, notamment pour les personnes a faible revenu. L'objectif de notre recherche est donc de tester en quoi le systeme de transport, et notamment les mesures relatives au cout du transport, contribuent ou compensent en partie les phenomenes d'exclusion reperes par ailleurs. Ainsi, les evolutions en matiere de politique tarifaire des reseaux de transports collectifs urbains au cours des dix dernieres annees marquent une extension de ces politiques, ainsi qu'une affectation des aides de plus en plus ciblee sur les populations les plus defavorisees, notamment selon des criteres de revenu. Une enquete aupres des structures locales d'accueil et d'insertion des agglomerations de Lyon, Nancy et Nantes, permet par ailleurs de qualifier et quantifier la part des difficultes liees au transport pour les personnes qui sont recues par ces structures.
Clonazepam for Refractory Headache: Three Cases Illustrative of Benefit and Risk

Many patients with migraine are poorly responsive to conventional preventive therapies. Comorbid anxiety and depression may contribute to headache refractoriness, but studies of headache preventives have not typically addressed the patient with psychiatric comorbidity. The author has used clonazepam empirically to treat a subgroup of headache patients with associated anxiety, who were poorly responsive to conventional preventives. The use of a benzodiazepine as a headache preventive raises concerns regarding tolerance and addiction. The author presents 3 cases that illustrate different outcomes associated with this therapy, and suggests guidelines for its use.
Real time two way communication approach for hearing impaired and dumb person based on image processing

In the recent years, there has been rapid increase in the number of deaf and dumb victims due to birth defects, accidents and oral diseases. Since deaf and dumb people cannot communicate with normal person so they have to depend on some sort of visual communication. Gesture shows an expressive movement of body parts such as physical movements of head, face, arms, hand or body which convey some message. Gesture recognition is the mathematical interpretation of a human motion by a computing device. Sign language provide best communication platform for the hearing impaired and dumb person to communicate with normal person. The objective of this research is to develop a real time system for hand gesture recognition which recognize hand gestures, features of hands such as peak calculation and angle calculation and then convert gesture images into voice and vice versa. To implement this system we use a simple night vision web-cam with 20 megapixel intensity. The ideas consisted of designing and implement a system using artificial intelligence, image processing and data mining concepts to take input as hand gestures and generate recognizable outputs in the form of text and voice with 91% accuracy.
Binaural interaction in brainstem potentials of human subjects

Binaural interaction in the short‐latency averaged auditory evoked potentials (AEPs) can be assessed from the binaural difference waveform (BD). The BD is derived by computing the difference between the AEP evoked by simultaneous clicks from both earphones and the sum of two other AEPs: one evoked by clicks from the right earphone alone and the other evoked by clicks from the left earphone alone. Once the contributions of acoustic cross talk and the middle ear reflex are eliminated, the BD can be considered to represent neural binaural interaction. This interaction begins after wave III and has its first major peak during the downslope of wave V. The relative amplitude of this peak to wave V is constant over a wide range of click rates and levels. The BD may have more localizing value than the AEPs alone since the BD probably represents a subpopulation of generators of the AEPs, which show binaural interaction at the single cell level.
Influence of Fermentation and Drying Materials on the Contamination of Cocoa Beans by Ochratoxin A

Ochratoxin A (OTA) is a mycotoxin produced mainly by species of Aspergillus and Penicillium. Contamination of food with OTA is a major consumer health hazard. In Côte d’Ivoire, preventing OTA contamination has been the subject of extensive study. The current study was conducted to evaluate the influence of fermentation and drying materials on the OTA content in cocoa. For each test, 7000 intact cocoa pods were collected, split open to remove the beans, fermented using 1 of 3 different materials, sun-dried on 1 of 3 different platform types and stored for 30 days. A total of 22 samples were collected at each stage of post-harvesting operations. The OTA content in the extracted samples was then quantified by high-performance liquid chromatography. OTA was detected in beans at all stages of post-harvesting operations at varying levels: pod-opening (0.025 ± 0.02 mg/kg), fermentation (0.275 ± 0.2 mg/kg), drying (0.569 ± 0.015 mg/kg), and storage (0.558 ± 0.04 mg/kg). No significant relationships between the detected OTA level and the materials used in the fermentation and drying of cocoa were observed.
Fully self-consistent GW calculations for atoms and molecules

We solve the Dyson equation for atoms and diatomic molecules within the GW approximation, in order to elucidate the effects of self-consistency on the total energies and ionization potentials. We find GW to produce accurate energy differences although the self-consistent total energies differ significantly from the exact values. Total energies obtained from the Luttinger-Ward functional ELW[G] with simple, approximate Green functions as input, are shown to be in excellent agreement with the self-consistent results. This demonstrates that the Luttinger-Ward functional is a reliable method for testing the merits of different self-energy approximations without the need to solve the Dyson equation self-consistently. Self-consistent GW ionization potentials are calculated from the Extended Koopmans Theorem, and shown to be in good agreement with the experimental results. We also find the self-consistent ionization potentials to be often better than the non-self-consistent G0W0 values. We conclude that GW calculations should be done self-consistently in order to obtain physically meaningful and unambiguous energy differences.
Effects of age on a real-world What-Where-When memory task

Many cognitive abilities decline with aging, making it difficult to detect pathological changes against a background of natural changes in cognition. Most of the tests to assess cognitive decline are artificial tasks that have little resemblance to the problems faced by people in everyday life. This means both that people may have little practice doing such tasks (potentially contributing to the decline in performance) and that the tasks may not be good predictors of real-world cognitive problems. In this study, we test the performance of young people (18–25 years) and older people (60+-year-olds) on a novel, more ecologically valid test of episodic memory: the real-world What-Where-When (WWW) memory test. We also compare them on a battery of other cognitive tests, including working memory, psychomotor speed, executive function, and episodic memory. Older people show the expected age-related declines on the test battery. In the WWW memory task, older people were more likely to fail to remember any WWW combination than younger people were, although they did not significantly differ in their overall WWW score due to some older people performing as well as or better than most younger people. WWW memory performance was significantly predicted by other measures of episodic memory, such as the single-trial learning and long-term retention in the Rey Auditory Verbal Learning task and Combined Object Location Memory in the Object Relocation task. Self-reported memory complaints also predicted performance on the WWW task. These findings confirm that our real-world WWW memory task is a valid measure of episodic memory, with high ecological validity, which may be useful as a predictor of everyday memory abilities. The task will require a bit more development to improve its sensitivity to cognitive declines in aging and to potentially distinguish between mentally healthy older adults and those with early signs of cognitive pathologies.

STAT3 blockade enhances the efficacy of conventional chemotherapeutic agents by eradicating head neck stemloid cancer cell

Signaling transducer and activator 3 (STAT3) and cancer stem cells (CSCs) have garnered huge attention as a therapeutic focus, based on evidence that they may represent an etiologic root of tumor initiation and radio-chemoresistance. Here, we investigated the high phosphorylation status of STAT3 (p-STAT3) and its correlation with self-renewal markers in head neck squamous cell carcinoma (HNSCC). Over-expression of p-STAT3 was found to have increased in post chemotherapy HNSCC tissue. We showed that blockade of p-STAT3 eliminated both bulk tumor and side population (SP) cells with characteristics of CSCs in vitro. Inhibition of p-STAT3 using small molecule S3I-201 significantly delayed tumorigenesis of spontaneous HNSCC in mice. Combining blockade of p-STAT3 with cytotoxic drugs cisplatin, docetaxel, 5-fluorouracil (TPF) enhanced the antitumor effect in vitro and in vivo with decreased tumor sphere formation and SP cells. Taken together, our results advocate blockade of p-STAT3 in combination with conventional chemotherapeutic drugs enhance efficacy by improving CSCs eradication in HNSCC.
Global Dynamical Solvers for Nonlinear Programming Problems

We construct a family of globally defined dynamical systems for a nonlinear programming problem, such that: (a) the equilibrium points are the unknown (and sought) critical points of the problem, (b) for every initial condition, the solution of the corresponding initial value problem converges to the set of critical points, (c) every strict local minimum is locally asymptotically stable, (d) the feasible set is a positively invariant set, and (e) the dynamical system is given explicitly and does not involve the unknown critical points of the problem. No convexity assumption is employed. The construction of the family of dynamical systems is based on an extension of the Control Lyapunov Function methodology, which employs extensions of LaSalle's theorem and are of independent interest. Examples illustrate the obtained results.
Clastogenic Effects of Glyphosate in Bone Marrow Cells of Swiss Albino Mice

Glyphosate (N-(phosphonomethyl) glycine, C3H8NO5P), a herbicide, used to control unwanted annual and perennial plants all over the world. Nevertheless, occupational and environmental exposure to pesticides can pose a threat to nontarget species including human beings. Therefore, in the present study, genotoxic effects of the herbicide glyphosate were analyzed by measuring chromosomal aberrations (CAs) and micronuclei (MN) in bone marrow cells of Swiss albino mice. A single dose of glyphosate was given intraperitoneally (i.p) to the animals at a concentration of 25 and 50 mg/kg b.wt. Animals of positive control group were injected i.p. benzo(a)pyrene (100 mg/kg b.wt., once only), whereas, animals of control (vehicle) group were injected i.p. dimethyl sulfoxide (0.2 mL). Animals from all the groups were sacrificed at sampling times of 24, 48, and 72 hours and their bone marrow was analyzed for cytogenetic and chromosomal damage. Glyphosate treatment significantly increases CAs and MN induction at both treatments and time compared with the vehicle control (P < .05). The cytotoxic effects of glyphosate were also evident, as observed by significant decrease in mitotic index (MI). The present results indicate that glyphosate is clastogenic and cytotoxic to mouse bone marrow.
School Job Placement: Can it Avoid Reproducing Social Inequalities?

Background Labor market entry is difficult for two-year college graduates. Job search literature focuses on personal connections, but disadvantaged students often lack useful contacts. Moreover, employers often don't recognize and value two-year college credentials as much as bachelor's degrees. Teacher contacts could help, but studies find that they can be biased against low achievers and minorities. Institutional school placement programs, which have the potential to reduce inequalities and help disadvantaged students in job search, have rarely been studied in the United States. Research Question How does schoolwide institutional job placement operate in a private two-year college with a highly developed program, and is it successful and equitable? Research Design This study uses a mixed-methods approach, including a qualitative case study and quantitative analysis of a single college's administrative records. Findings We find that this college created institutional job links that are different from other programs studied in the United States. It equitably serves most students and is unrelated to achievement or race. Although it does not improve students’ postcollege earnings, it does improve the skill relevance of participants’ postcollege jobs, which is a potentially important indicator of long-term success. Black and Hispanic students who use the program have earnings advantages over Whites, but this is not true for those who find jobs on their own. Conclusions Job placement can and does occur in two-year colleges in the United States. When programs are institutional rather than based on personal teacher contacts, they can serve students equitably and potentially reduce preexisting social inequalities. Colleges can effectively do job matching between the labor market and their students’ qualifications. In so doing, they can provide useful recommendations to employers and place students in skill-relevant jobs.
Review of materials in medical applications

Medical implants are products that have to satisfy functionality demands defined by the human body as working environment. Ideally, they should have biomechanical properties comparable to those of autogenous tissues without any adverse effects and are regulated in order to ensure safety and effectiveness. The choice of material used for designing a medical implant is governed by biocompatibility, bioadhesion, biofunctionality, corrosion resistance, etc. In these review metallic biomaterials are divided into four subgroups: stainless steels, the cobalt alloys, titanium alloys, and other metals. Some attention is also given to shape memory, polymeric, and ceramic biomaterials for their innovative use in practical medical applications. Izvleček: Medicinski vsadki so izdelki, ki morajo zadovoljiti stroge funkcijske zahteve, ki jih narekuje človeško telo kot delovno okolje. V idealnem primeru naj bi imeli biomehanske lastnosti primerljive avtogenim tkivom brez škodljivih efektov in so evidentirani, da zagotavljajo varnost in uspešnost. Izbira materiala pri načrtovanju medicinskih vsadkov je pogojena z biokompatibilnostjo, bioadhezijo, biofunkcionalnostjo, korozijsko odpornostjo, itd. V tem pregledu so kovinski biomateriali razdeljeni v štiri podskupine: nerjavna jekla, kobaltove zlitine, titanove zlitine in druge kovine. Nekaj pozornosti je posvečene tudi zlitinam s spominom, polimernim in keramičnim biomaterialom zaradi njihove inovativne uporabe v praktičnih medicinskih aplikacijah.
The Properties of Ultraviolet-luminous Galaxies at the Current Epoch

We have used the first matched set of Galaxy Evolution Explorer (GALEX) and Sloan Digital Sky Survey (SDSS) data to investigate the properties of a sample of 74 nearby (z < 0.3) galaxies with far-ultraviolet luminosities greater than 2 × 1010 L☉, chosen to overlap the luminosity range of typical high-z Lyman break galaxies (LBGs). GALEX deep surveys have shown that ultraviolet-luminous galaxies (UVLGs) similar to these are the fastest evolving component of the UV galaxy population. Model fits to the combined GALEX and SDSS photometry yield typical FUV extinctions in UVLGs of 0.5-2 mag (similar to LBGs and less luminous GALEX-selected galaxies). The implied star formation rates are SFR ~ 3-30 M☉ yr-1. This overlaps the range of SFRs for LBGs. We find a strong inverse correlation between galaxy mass and FUV surface brightness, and on this basis we divide the sample into "large" and "compact" UVLGs. The large UVLGs are relatively massive (M* ~ 1011 M☉) late-type disk galaxies forming stars at a rate similar to their past average (M*/SFR ~ tHubble). They are metal rich (approximately solar), have intermediate optical-UV colors (FUV - r ~ 2-3), and about a third host a type 2 (obscured) active galactic nucleus. In contrast, the compact UVLGs have half-light radii of a few kpc or less (similar to LBGs ). They are relatively low-mass galaxies (M* ~ 1010 M☉) with typical velocity dispersions of 60-150 km s-1. They span a range in metallicity from ~0.3 to 1 times solar, have blue optical-UV colors (FUV - r ~ 0.5-2), and are forming stars at a rate sufficient to build the present galaxy in ~1-2 Gyr. In all these respects they appear similar to the LBG population. These "living fossils" may therefore provide an opportunity for detailed investigation of the physical processes occurring in typical star-forming galaxies in the early universe.
