Growth and characterization of sulphamic acid single crystals grown by Sanakaranarayanan‐Ramasamy (SR) method
Authors: Lenin M. , Balamurugan N. , Ramasamy P. 
Published: December 2006

AbstractBy directional solidification, single crystal of Sulphamic acid (SA) was successfully grown from aqueous solution by Sankaranarayanan‐Ramasamy (SR) method. A vertically designed L‐bend was used to avoid the effect due to spurious nucleation. A vertical bottom‐seeded ampoule was used for the growth of single crystal. A seed crystal was mounted at the bottom of the ampoule. Sulphamic acid crystals of up to 40 mm in diameter and 60 mm in length have been grown with a growth up to 10 mm per day. The grown sulphamic acid single crystal was characterized using X‐ray powder diffraction analysis, Raman, FTIR, and optical transmission studies. The dielectric behaviour was measured in the frequency range of 1 kHz–10 MHz for the temperature ranges from 30 °C to 170 °C. The sulphamic acid single crystal was also grown by conventional method.

Transgene expression of prion protein induces crinophagy in intermediate pituitary cells
Authors: van Rosmalen Jos W.G. , Martens Gerard J.M. 
Published: December 2006

AbstractThe cellular form of the prion protein (PrPC) is a plasma membrane‐anchored glycoprotein whose physiological function is poorly understood. Here we report the effect of transgene expression of Xenopus PrPC fused to the C‐terminus of the green fluorescent protein (GFP‐PrPC) specifically in the neuroendocrine intermediate pituitary melanotrope cells of Xenopus laevis. In the transgenic melanotrope cells, the level of the prohormone proopiomelanocortin (POMC) in the secretory pathway was reduced when the cells were (i) exposed for a relatively long time to the transgene product (by physiologically inducing transgene expression), (ii) metabolically stressed, or (iii) forced to produce unfolded POMC. Intriguingly, although the overall ultrastructure was normal, electron microscopy revealed the induction of lysosomes taking up POMC secretory granules (crinophagy) in the transgenic melanotrope cells, likely causing the reduced POMC levels. Together, our results indicate that in neuroendocrine cells transgene expression of PrPC affects the functioning of the secretory pathway and induces crinophagy. © 2006 Wiley Periodicals, Inc.

Comparing the effects of determinants of turnover intentions between Taiwanese and U.S. hospital employees
Authors: Ding Cherng G. , Lin Chieh‐Peng 
Published: December 2006

AbstractThis research assesses how the direct effects of career satisfaction and job satisfaction on turnover intentions and the indirect effects through organizational commitment differ between Taiwanese and U.S. hospital employees. Using data collected from 179 Taiwanese and 144 U.S. hospital employees, the test results find the following differences: the direct effect of job satisfaction on turnover intentions is negative and significant for Taiwanese hospital employees but not for U.S. hospital employees; the indirect effect of job satisfaction on turnover intentions through organizational commitment is stronger for Taiwanese hospital employees than for U.S. hospital employees; and the negative direct effect of career satisfaction on turnover intentions and the indirect effect through organizational commitment are stronger for U.S. hospital employees than for Taiwanese hospital employees. Finally, the managerial implications for human resource development are discussed.
Why we fail: How hubris, hamartia, and anagnosis shape organizational behavior
Authors: Ford Randal 
Published: December 2006

AbstractThis article presents three tendencies (hubris, hamartia, and anagnosis) to explain why organizational personnel are prone to fail. All people are subject to these tendencies. Few organizations or individuals understand them, however, and fewer still know how to manage them. The article employs short case studies to define them and offers solutions on how to overcome their impact.

Published: December 2006

AbstractThe epithelial membrane protein 3 (EMP3) gene located on chromosome 19q13 has been implicated as a candidate tumor suppressor gene (TSG) in neuroblastomas and gliomas. The aim of this study was to investigate whether EMP3 is involved in oligodendroglial tumors (OTs), which frequently carry combined chromosomes 1p and 19q deletion. We first investigated the transcript level of EMP3 in a cohort of 57 OTs by quantitative real‐time RT‐PCR. Our results showed that 10 (18%) tumors had reduced EMP3 expression level compared to normal brains. Six of these tumors carried chromosome 19q13 deletion but no statistical correlation was found between the 2 parameters. Intriguingly, a similar proportion (11 of 57, 19%) of tumors displayed EMP3 overexpression, with 8 of them having transcript level >10‐fold higher than normal brain. All 11 OTs retained chromosomes 1p36 and 19q13, and a significant association was found between EMP3 overexpression and balanced chromosomes 1p36 and 19q13 (p = 0.004). The methylation status of EMP3 was evaluated by bisulfite sequencing in 29 OTs with diverse expression levels. All tumors except 3 showed aberrant methylation of EMP3 and no correlation was observed between transcript level and methylation status, suggesting that methylation alone does not mediate transcriptional down‐regulation of EMP3 in OTs. In conclusion, our study demonstrates that EMP3 overexpression is involved in OTs retaining chromosomes 1p and 19q and does not support EMP3 as the target TSG on chromosome 19q13 in OTs. © 2006 Wiley‐Liss, Inc.
Development of wollastonite‐poly(ethylmethacrylate co‐vinylpyrrolidone) based materials for multifunctional devices
Authors: Rodríguez‐Lorenzo Luis M. , Carrodeguas Raúl García , Rodríguez Miguel A. , De Aza Salvador , Parra Juan , Román Julio San 
Published: December 2006

AbstractThe manufacturing of a composite made of a synthetic bioactive ceramic, pseudowollastonite (psW), and a bioresorbable copolymer ethylmethacrylate–vinylpyrrolidone (EMA/VP) is presented in this article. psW porous blocks were produced by dipping an open porous polyurethane foam in a psW containing slurry. A 40/60 wt % EMA/VP monomers mixture was poured on the blocks, and free radical polymerization initiated by azobis(isobutyronitrile) at 50°C. Disks of 1 mm height were obtained by cutting the composite with a diamond saw, and bioresorption and bioactivity of the specimens were tested by immersion of the disks into SBF. A ceramic/polymer weight ratio of 72/28, greater than the usually achievable ratio by polymeric solidification of slurries of monomers charged with a powdered solid component, has been obtained. The system is bioactive and does not change the pH of the medium during the degradation test. © 2006 Wiley Periodicals, Inc. J Biomed Mater Res 80A:, 2007
Flow cytometric analysis of Saccharomyces cerevisiae populations in high‐sugar Chardonnay fermentations
Authors: Farthing Jeffrey B , Rodriguez Susan B , Thornton Roy J 
Published: December 2006

AbstractFermentation of high‐sugar grape juice by five commercial strains of Saccharomyces cerevisiae was analyzed in real time both microbiologically and chemically. Viable, dead and ‘injured’ yeast were enumerated by flow cytometry. Chemical changes in the fermentations were measured by Fourier transform infrared spectroscopy. Sensory testing of wines was conducted at 3 and 6 months post bottling. Fermentation kinetics varied among the five strains of yeast, with two of the yeasts unable to completely ferment the juice. Wines differed in glycerol and volatile acidity production. Sensorial differences were detected in all wine pairs tested at 3 months, but only in one of the four wine pairs tested at 6 months.

AbstractObjectivesOur objective was to identify the clinical consequences of deep‐hidden anastomoses that occur underneath the placental surface.MethodsTwelve placentae that underwent intrauterine laser ablation of placental anastomoses for twin–twin transfusion syndrome (TTTS) and 14 non‐TTTS controls were investigated for deep‐hidden anastomoses. Additionally, we investigated the inter‐twin haemoglobin differences as an indicator for fetofetal transfusion. Placentae were divided into four groups: TTTS placentae without residual chorionic‐plate anastomoses without deep‐hidden anastomoses (group 1) and with deep‐hidden anastomoses (group 2), and non‐TTTS placentae with chorionic‐plate anastomoses without deep‐hidden anastomoses (group 3) and with deep‐hidden anastomoses (group 4).ResultsDeep‐hidden anastomoses were identified in 58% (7/12) of the TTTS placentae after laser surgery and in 64% (9/14) of the non‐TTTS placentae. Groups 1 and 2 had equal inter‐twin haemoglobin differences: medians 1.4 and 1.2 gr/dL, respectively (p = 0.48). In group 3, the median inter‐twin haemoglobin difference without deep‐hidden anastomoses was 2.6 gr/dL (group 3) and with deep‐hidden anastomoses (group 4) it was 5.1 gr/dL (p = 0.26).ConclusionBoth comparisons imply that deep‐hidden anastomoses did not cause any additional increase in Hb difference. In conclusion, haematological and additional hemodynamical analysis show that deep‐hidden anastomoses are likely to occur without any clinical consequences. Copyright © 2006 John Wiley & Sons, Ltd.
Time‐variance of interacting dipole systems
Authors: Kühn M. , Kliem H. 
Published: December 2006

AbstractIn a previous paper we performed numerical calculations of transient polarization relaxations for an interacting system of statistically distributed permanent dipoles. These simulations in the time‐domain showed the typical Kohlrausch relaxation law. Now the relaxating system is tested for time‐invariance. Using the dependencies of the dielectric circle integral transformations between time domain and frequency domain are carried out and are compared to our Monte Carlo simulations. The following simulation of the field reversal experiment based on the superposition principle for the polarization or rather current density demonstrates an alternative of testing a system for the properties of linearity and time‐invariance. The interacting systems exhibit a time‐variant character. In this paper we focus on the small signal response after applying a step function of the electric field. (© 2007 WILEY‐VCH Verlag GmbH & Co.

Enhanced reductive dechlorination of PCE in unconsolidated soils
Authors: Payne Fred C. , Suthersan Suthan S. , Nelson Denice K. , Suarez Gus , Tasker Ian , Akladiss Naji 
Published: December 2006

AbstractAn Interstate Technology and Regulatory Council (ITRC) forum was recently held that focused on six case studies in which bioremediation of dense nonaqueous phase liquids (DNAPLs) was performed. The objective was to demonstrate that there is credible evidence for bioremediation as a viable environmental remediation technology. A discussion of the first case study from the ITRC forum was published in the previous issue of Remediation. This article presents a discussion of the second case study, which involves enhanced reductive dechlorination (ERD) of tetrachloroethene (PCE) in unconsolidated soils—primarily silts and clays with very low permeabilities. The project results indicate that complete reductive dechlorination was achieved and provide encouragement that large amounts of nonaqueous solvent can be brought into the reductive dechlorination treatment process by dissolution and desorption, giving support to the contention that the capacity to attack nonaqueous mass is a prerequisite for any effective treatment of DNAPL source zones. The site geology for this project was relatively unfavorable, and further work is needed to confirm that the ERD technology can economically reach a natural attenuation endpoint for this type of setting. © 2006 Wiley Periodicals, Inc.
Before‐after control‐impact paired modeling of groundwater bentazon treatment at a phytoremediation site
Authors: Conger Robert Mark , Portier Ralph J. 
Published: December 2006

AbstractA Before‐ After Control‐ Impact Paired (BACIP) model was used to evaluate the effectiveness of phytoremediation treatment on reduction of bentazon concentrations in shallow groundwater at a study site in Louisiana. Two different statistical approaches were made to evaluate the impact to this test site from the remediation program through time. Data were evaluated by Bayesian analysis of variance test methods. Data sets were unique in that the control data used for impact evaluation, as compared to before and after data, were compiled from groundwater upgradient monitoring wells existing prior to remediation. The statistical model supports the hypothesis that the phytoremediation program has positively impacted groundwater at the study site. © 2006 Wiley Periodicals, Inc.
Curriculum integration in nursing education: a concept or a way of life? A study of six courses integrating basic nursing education and health visiting in a single course
Authors: Owen Grace M. 
Published: December 2006

The purpose of this study was to record the historical development of ‘integrated’ nursing courses, which were an innovation in nursing education, and also to attempt to identify any differences existing between health visitors who trained on ‘integrated’ courses and those who had trained on the 3‐year SRN courses, with an additional year for health visiting. The ‘integrated’ courses, first established in 1957, aimed to attract intelligent candidates to nursing and to offer a more appropriate method of preparation for health visiting between hospital and university or college, integrating hospital nursing with health visiting.The original area of investigation was carried out by means of unstructured questionnaires to all health visitors completing the ‘integrated’ courses in 1972, and a comparable group of health visitors completing the 1‐year course at the same point in time. Certain significant differences were identifiable between the two groups in terms of expectations, values and satisfactions in nursing and health visiting, and differences also emerged between the stereotypes of nursing and health visiting held by both groups.A further study carried out among employers revealed some interesting attitudes held by their professional colleagues towards those trained on ‘integrated’ courses, and gave some indication of the ways in which their performance was evaluated by nursing officers and others. The concluding discussion outlines some of the possible implications of diese findings in the context of present day nursing education in the United Kingdom and an integrated health service.
Academic gaming in nurse education
Authors: French Peter 
Published: December 2006

SUMMARYThis paper describes a study of the usefulness of academic gaming in nurse education. The research has been carried out over the course of 3 years and represents an attempt by a nurse tutor to carry out a study on research lines, during the course of normal working and with a minimum of interference to the normal working of a nurse education department.The study involved psychiatric nurse learners at Winterton Hospital, Sedgefield, Durham and attempted to assess the usefulness of academic gaming by evaluating one academic game which has been designed for nurse learners. This game aims to teach various aspects of the digestive system and digestive processes. The questions which required answers were, can nurse learners learn from academic games? Do they like this method of learning? How does this method compare with other learning methods?Eighty‐six learners participated in a test/game/test situation and completed a questionnaire after playing the game. Results suggest that learners can increase their knowledge of the subject by playing the game but it may be most useful as a consolidation method. Learners most often stated that they enjoyed the game and when ranked according to preference, gaming was preferred to film, reading and discussion methods but equally preferred to the lecture method.
Hospital ward layout and nurse staffing*
Authors: Seelye Alan 
Published: December 2006

This literature review discusses the evidence that modem wards divided into small bedrooms or bays, require higher nurse staffing levels. Aspects of ward design and operation such as patient privacy, nursing efficiency, patient dependency and ward organization are outlined and methods for establishing staffing levels which take ward design into account are described. The majority of ward evaluation studies concerned with nurse staffing concentrate on two areas, the use of the nurses’ time (particularly in travel) and user opinion of wards.The conclusions drawn suggest that the two main measures of ward layout which relate to effective and efficient nursing care are short travel distances and features which facilitate the maximum contact between nurses and patients. Further, how these two principles are incorporated effectively into a ward will depend upon a number of other factors which effect nursing work viz, the number and characteristics of the patients and ward staff and the policies and practices of the nurses themselves.
Ward sister – teacher or facilitator? An investigation into the behavioural characteristics of effective ward teachers
Authors: Marson S. N. 
Published: December 2006

The ward sister role is increasingly coming under study. This paper summarizes research into learning in the ward environment. The study being one of several on a similar theme, to have been published in the past 2 years. The research concentrated in particular on the behavioural characteristics of trained nurses perceived as good teachers. Attitudes and perceptions of teaching and learning were investigated by interviewing trained and trainee nurses.The data concerning good teachers collected at interviews were developed into a questionnaire and the results factor analysed. In the third phase of the study trained nurse‐trainee verbal communications were observed and analysed to determine any relationship between verbal behaviours and effective teaching.The findings of the study led to the conclusion that on the job teaching of nurses is a complex global act in which the role model presented to the learner has a powerful influence while it could not be said conclusively that a link between effective teaching and verbal behaviour was identified, a trend towards a more participative mode of communication was noted in two identified good teachers.
