Kinetics of the hydrogen abstraction ROH + H → RO• + H2 reaction class
Authors: Ratkiewicz Artur , Truong Thanh N. 
Published: April 2010

AbstractThis paper presents an application of the reaction class transition state theory (RC‐TST) to predict thermal rate constants for the hydrogen abstraction ROH + H → RO• + H2 reaction class, where R is an alkyl group. We have derived all parameters for the RC‐TST method for this reaction class from rate constants of 19 representative reactions, coupling with linear energy relationships (LERs) and the barrier height grouping (BHG) approach. Error analyses indicate that the RC‐TST/LER, where only reaction energy is needed, and RC‐TST/BHG, where no other information is needed, can predict rate constants for any reaction in this reaction class with satisfactory accuracy for combustion modeling. Specifically for this reaction class, the RC‐TST/LER method has less than 25% systematic errors in the predicted rate constants, whereas the RC‐TST/BHG method has less than 35% error when compared to explicit rate calculations. © 2010 Wiley Periodicals, Inc.

A linear solvation energy relationship study for the reactivity of 2‐(4‐substituted phenyl)‐cyclohex‐1‐enecarboxylic, 2‐(4‐substituted phenyl)‐benzoic, and 2‐(4‐substituted phenyl)‐acrylic acids with diazodiphenylmethane in various solvents

Published: April 2010

AbstractThe reactivities of 2‐(4‐substituted phenyl)‐cyclohex‐1‐enecarboxylic acids, 2‐(4‐substituted phenyl)‐benzoic acids, and 2‐(4‐substituted phenyl)‐acrylic acids with diazodiphenylmethane in various solvents were investigated. To explain the kinetic results through solvent effects, the second‐order rate constants of the examined acids were correlated using the Kamlet–Taft solvatochromic equation. The correlations of the kinetic data were carried out by means of multiple linear regression analysis, and the solvent effects on the reaction rates were analyzed in terms of initial and transition state contributions. The signs of the equation coefficients support the proposed reaction mechanism. The solvation models for all investigated carboxylic acids are suggested. The quantitative relationship between the molecular structure and the chemical reactivity is discussed, as well as the effect of geometry on the reactivity of the examined molecules. © 2010 Wiley Periodicals, Inc.

Building a process‐based organization: The design roadmap at Superjet International
Authors: Corallo Angelo , Margherita Alessandro , Scalvenzi Massimo , Storelli Davide 
Published: April 2010

AbstractThe benefits of managing companies through a process‐based approach are well recognized in the business literature and in many corporate contexts. However, there is a limited discussion on how to practically design and develop an organization based on processes. This paper aims to address this relative ‘gap’ in the literature by presenting the case of a recent international joint venture in the regional jet industry. In the following paper, we present a story of organization design based on the identification and description of the core process model of the company, with a specific focus on customer service activities. Based on interviews and direct observation at the field site, this paper shows the main steps undertaken to define the process taxonomy levels and to describe process elements, along with a discussion of the relationships with the business model components of the company. The paper provides practical value as it provides practical insights relating to the start‐up of a new company driven by a process‐based approach. Copyright © 2010 John Wiley & Sons, Ltd.
New product development for a food and beverage company: A showcase of evidence‐based management
Authors: Man Derek C. , Lui Steven S. , Lai John 
Published: April 2010

AbstractWe develop a model of new product development which may inform decision‐making on innovation and knowledge management in this paper. The new model combines extant theoretical framework and actual practice from a leading Food and Beverage chain in Hong Kong to illustrate how evidence‐based management (EBM) can be practiced in new product development. Some salient features of the model include generating new ideas constantly, improving success rate of new ideas, and ensuring collaboration among internal functions. This paper showcases EBM by synthesizing theoretical knowledge and practical wisdom and bringing together academics and practitioners to better understand a new product development model that can be generalized to other companies and industries.

The effect of organizational culture on knowledge management practices and innovation
Authors: Donate Mario J. , Guadamillas Fátima 
Published: April 2010

AbstractIn this paper we analyze the relationships between certain knowledge management (KM) practices, organizational culture, and the technological results of companies. In the last few years, KM literature has highlighted the important role of cultural values on the way KM processes are developed and applied in organizations. From this viewpoint, and focusing on a set of knowledge storage and transfer practices, we try to empirically analyze the existence of a multiplier effect of the knowledge‐centered organizational culture on the relationship between these kinds of knowledge practices and the technological performance of firms. The results of the empirical study show the existence of a significant moderating effect, although the consequences on the innovative performance in terms of product or process technologies are found to be different, depending on the practice (storage or transfer) which is considered.

Comparative supply chain performance: Measuring cross‐cultural effects. The example of the Bratislava regional automotive manufacturing cluster
Authors: Bardy Roland 
Published: April 2010

AbstractThis paper examines how performance in a supply network is biased through cultural difference. Based on a benchmark study for the Bratislava automotive cluster, the review covers the specific situation of a cross border setting where top performers (high‐class original equipment manufacturers, “OEMs,” like VW, Peugeot, Porsche, Kia) in a dual economy environment interact with suppliers from a highly developed country and with local logistics service enterprises. The main findings were derived from a benchmarking questionnaire and were corroborated in subsequent interviews, and they can very well be generalized: specific knowledge required for interactions between buyers and sellers cannot be built and utilized effectively if acceptance, adaptation and integration are obstructed by cultural differences. The biggest threats to fully exploiting the opportunities of cross‐border supply chains, are lack of trust and of ability or willingness to cooperate and insufficient power of decision‐making; lack of application skills ranks second.

Electron spin resonance spectroscopy: a promising method for studying lipid oxidation in foods
Authors: Roman Olesea , Maillard Marie‐Noëlle , Plessis Cédric , Riquet Anne‐Marie 
Published: April 2010

AbstractOxidative reactions that involve lipids are among the most important causes of deterioration of foods and affect both their shelf life and their organoleptic and nutritional properties. Radicals are intermediate key‐constituents in these reactions. Their detection is therefore essential in order to understand and predict early stages of these destructive oxidations. Several Electron Spin Resonance (ESR) methodologies (direct and indirect) make it possible to identify, quantify and measure the reactivity of radical species formed during oxidative‐reductive reactions. They are also used to evaluate the antiradical activity of antioxidants delaying lipid oxidation. An overview on the use of different ESR methodologies to study lipid oxidation in foods is reported in this paper.
Protection of biodiesel against oxidation
Authors: Ingendoh Axel 
Published: April 2010

AbstractThe importance of using synthetic antioxidants to improve oxidation stability and shelf life of biodiesel is today generally accepted. In our investigations which started early with the development of biodiesel we have looked at the course of stability, ageing of biodiesel, and the use of synthetic antioxidants. We have shown for the first time that oxidative stability of biodiesel is lower than that of the rape seed oil from which it was produced. The natural stability of biodiesel relates mainly to the content of tocopherols which survive the transesterification process. Biodiesel freed from tocopherols has no stability and will be destroyed immediately in air. Synthetic antioxidants like BHT and the newly developed stronger “Bis‐BHT” dramatically improve oxidative stability and prolong shelf life. Biodiesel rich in polyunsaturated fatty acid methyl ester needs strong antioxidants to be sufficiently protected. The class of hindered phenolic antioxidants from which the BHT and “Bis‐BHT” derive are well suited as industrial biodiesel stabilizer because of their ready availability, sufficient effectiveness and proven safety in diesel fuel. Surprisingly, none of the approved international biodiesel and biodiesel blend specifications refer to shelf life as a quality parameter. There is no definition of shelf life available, although it is well understood that biodiesel ages and loses its oxidative stability over time. We propose to consider the time span from production until the biodiesel reaches zero oxidative stability and becomes rancid and detrimental for the engine as the “shelf life” of biodiesel. From the perspective of a customer running their car on biodiesel blends, shelf life should become a more important issue.

Published: April 2010

AbstractPerfluoropolyethers are a well known and widely used family of polymers, suitable as protectives. Their main drawback is the lack of solubility, which is complete only in chlorofluorocarbons. In this work a series of A‐B‐A block copolymers (FluoPLA), with a relative low molecular weight, were prepared by ROP of L‐ and D,L‐lactide (PLA) in the presence of a hydroxy‐terminated perfluoropolyether as macroinitiator. In fact the use of block copolymers leads to different advantages, i.e. a limited segregation phenomena and higher polymer solubility. The resulting polymers were characterized (by NMR, IR, HPLC‐SEC, DSC, LS) and tested as potential protective and surface modifiers for cultural heritage (ESEM‐EDS, solar‐box technique, colorimeter analysis).magnified image
Synthesis of Spherical Polyelectrolyte Brushes by Thermo‐controlled Emulsion Polymerization
Authors: Wang Xiang , Xu Jun , Li Li , Wu Shuang , Chen Qingchuan , Lu Yan , Ballauff Matthias , Guo Xuhong 
Published: April 2010

AbstractA novel method of thermo‐controlled emulsion polymerization has been employed to synthesize spherical polyelectrolyte brushes that consist of a solid polystyrene core and a poly (acrylic acid) (PAA) shell covalently attached on the core surface densely by one end. The growth of brushes from the core surface was monitored by dynamic light scattering (DLS). The particle size of PS core latex showed a narrow size distribution when observed by scanning electron microscopy (SEM). The brush size changed significantly upon changing pH value and ionic strength, and displayed similar behavior to brushes prepared by photo‐emulsion polymerization. The grafting density of the PAA brush, which was determined by cutting off the PAA chains using alkali hydrolysis, confirmed the formation of PAA brushes.magnified image
Modelling lifetime QALYs and health care costs from different drinking patterns over time: a Markov model
Authors: Barbosa Carolina , Taylor Benjamin , Godfrey Christine , Rehm Juergen , Parrott Steve , Drummond Colin 
Published: April 2010

AbstractThe negative health consequences of alcohol use and its treatment account for significant health care expenditure worldwide. Long‐term modelling techniques are developed in this paper to establish a link between drinking patterns, health consequences and alcohol treatment effectiveness and cost‐effectiveness. The overall change in health related quality and quantity of life which results from changes in health‐related behaviour is estimated. Specifically, a probabilistic lifetime Markov model is presented where alcohol consumption in grams of alcohol per day and drinking history are used for the categorization of patients into four Markov states. Utility weights are assigned to each drinking state using EQ‐5D scores. Mortality and morbidity estimates are state, gender and age specific, and are alcohol‐related and non‐alcohol‐related. The methodology is tested in a case study. This represents a major development in the techniques traditionally used in alcohol economic models, in which short‐term costs and outcomes are assessed, omitting potential longer term cost savings and improvements in health related quality of life. Assumptions and implications of the approach are discussed. Copyright © 2010 John Wiley & Sons, Ltd.
Modeling of bearing capacity of footings on sand within stochastic micro‐polar hypoplasticity
Authors: Tejchman J. , Górski J. 
Published: April 2010

AbstractThe effect of the initial distribution of void ratio on strength and shear localization in problems of footings on sand at laboratory scale was numerically analyzed. To describe a mechanical behavior of a cohesionless granular material during a monotonic deformation path, a micro‐polar hypoplastic constitutive model was used. The initial void ratios took the form of correlated random spatial fields described by both symmetric and non‐symmetric random distributions using a homogeneous correlation function. The field realizations were obtained with the help of an original conditional rejection method of generation. Only few representative samples of the random fields selected from the generated set were taken into account in the numerical calculations. The stochastic results were compared with deterministic ones performed with a uniform distribution of initial void ratio. In addition, the effect of the range of correlation was investigated. Finally, a size effect was calculated with three different footing widths. Copyright © 2010 John Wiley & Sons, Ltd.

Published: April 2010

AbstractThe purpose of this evaluation was to study the relationship of nurse care coordination (NCC) to the costs of Medicare and Medicaid in a community‐based care program called Missouri Care Options (MCO). A retrospective cohort design was used comparing 57 MCO clients with NCC to 80 MCO clients without NCC. Total cost was measured using Medicare and Medicaid claims databases. Fixed effects analysis was used to estimate the relationship of the NCC intervention to costs. Controlling for high resource use on admission, monthly Medicare costs were lower ($686) in the 12 months of NCC intervention (p = .04) while Medicaid costs were higher ($203; p = .03) for the NCC group when compared to the costs of MCO group. © 2010 Wiley Periodicals, Inc.

Published: April 2010

Abstract

The author seeks to demonstrate that process rather than personalities are the key to understanding political situations and their public affairs implications. He reviews the outcome of changes in EU process during the tumultuous twelve months ending in December 2009, concluding that the European Union has moved into a new phase where constitutional issues are of substantially reduced importance. He notes the increased influence of the European Parliament. He comments on the implications for politics in both Europe and America in the light of the power shift made apparent at the Climate Change Conference in Copenhagen.

Published: April 2010

AbstractBackgroundBacteremias are frequent during induction therapy for acute lymphoblastic leukemia (ALL) in children. Antibacterial prophylaxis therapy may thus be warranted. The purpose of this study was to analyze the rate of infections during induction therapy in two cohorts of children with ALL where one cohort received prophylactic sulfamethoxazole–trimethoprim (SMX–TMP).ProcedureAll infections were registered through a retrospective non‐randomized review of medical records of 171 consecutive children newly diagnosed with ALL below 15 years of age at diagnosis. A total of 85 children treated from 1992 to 2000 did not receive SMX–TMP, whereas 86 children treated from 2000 to 2008 received SMX–TMP 20 mg/kg in one daily oral dose during induction therapy.ResultsA total of 26% of all children had no febrile episodes during induction. Infections were more frequent in children below 5 years of age. Significantly fewer children receiving SMX–TMP developed fever (17% vs. 34%, P = 0.02) and bacteremia (20% vs. 45%, P = 0.0003). Especially children with non‐high risk criteria had fewer infections when receiving prophylaxis. When adjusting for age, type of catheter, and SMX–TMP prophylaxis on the risk of bacteremia by a multiple Cox regression analysis, we found that age and prophylaxis, but not the type of catheter, were associated with a significantly reduced risk of bacteremia.ConclusionChildren with ALL receiving SMX–TMP prophylaxis during induction therapy experienced fewer febrile episodes, fewer days with fever demanding intravenous antibiotic treatment, and fewer episodes of bacteremia. Both SMX–TMP prophylaxis and age played significant independent roles for the occurrence of bacteremia. Pediatr Blood Cancer. 2010;55:304–308. © 2010 Wiley–Liss, Inc.

AbstractBackgroundMolecular detection of tyrosine hydroxylase (TH) transcripts by quantitative RT‐PCR (qRT‐PCR) is a sensitive method to detect neuroblastoma (NB) cells in the bone marrow (BM). However, its clinical utility following chemotherapy has not been thoroughly investigated.ProceduresTH transcripts in the BM were measured by qRT‐PCR both at diagnosis and during the course of chemotherapy. The results were analyzed with respect to assay timing, tumor volume and histological findings.ResultsTH transcripts were detected in 100% of BM aspirates at diagnosis in cases with concurrent tumor involvement in the BM section; however, the proportion of TH transcript positive BM aspirates in cases with concurrent tumor involvement in the BM section gradually decreased following chemotherapy (55.5% after three cycles, 28.6% after six cycles and 0% after nine or more cycles of chemotherapy). Decreased proportion of TH transcript positive BM aspirates was associated with reduced tumor volume in the BM and differentiation of tumors into mature forms during chemotherapy. When qRT‐PCR was performed with both aspirated and biopsied tissue during chemotherapy, TH transcripts were detected in BM tissue not only in all of the histology‐positive cases but also in some of the histology‐negative cases, while the proportion of TH transcript positive BM aspirates was low, even in histology‐positive cases.ConclusionsMeasurement of TH transcripts in BM aspirates does not appear to be clinically useful during or after chemotherapy. Therefore, molecular monitoring of NB cells during or after chemotherapy using BM tissue is more optimal than testing on BM aspirates. Pediatr Blood Cancer. 2010;55:273–278. © 2010 Wiley–Liss, Inc.
Meta‐analyses of the effect of false‐positive mammograms on generic and specific psychosocial outcomes
Authors: Salz Talya , Richman Alice R. , Brewer Noel T. 
Published: April 2010

AbstractObjectives: While a previous meta‐analysis found that false‐positive mammography results affect women's likelihood of returning for screening, effects on well being have yet to be meta‐analyzed. We investigated whether the effects of false‐positive mammograms on women's well‐being are limited to outcomes specific to breast cancer.Methods: We searched MEDLINE for studies of the psychosocial effects of false‐positive results of routine screening mammography. We pooled effect sizes using random effects meta‐analysis.Results: Across 17 studies (n=20 781), receiving a false‐positive mammogram the result was associated with differences in all eight breast‐cancer‐specific outcomes that we examined. These included greater anxiety and distress about breast cancer as well as more frequent breast self‐exams and higher perceived effectiveness of screening mammography. False positives were associated with only one of six generic outcomes (i.e. generalized anxiety), and this effect size was small.Conclusions: False‐positive mammograms influenced women's well‐being, but the effects were limited to breast‐cancer‐specific outcomes. Researchers should include disease‐specific measures in future studies of the consequences of false‐positive mammograms. Copyright © 2010 John Wiley & Sons, Ltd.
