Fuzzy evaluation of risk management profiles disclosed in corporate annual reports
Authors: Dia Mohamed , Zéghal Daniel 
Published: August 2008

AbstractThe most common measures of risk have traditionally been based on quantitative financial and accounting information. However, new information on risk management disclosed in companies' annual reports is generally qualitative or linguistic. As such, exploitation by decision makers becomes difficult. In this study, a fuzzy analysis approach is applied to risk information disclosed by 217 firms listed on the Toronto Stock Exchange. The results provide some evidence that these fuzzy measures are reasonable proxies for traditional financial and accounting measures. They also show that fuzzy measures can predict a significant amount of systematic risk. Copyright © 2008 ASAC. Published by John Wiley & Sons, Ltd.
Theoretical Study on the Vibrational Spectra and Thermodynamic Properties for Nitro Derivatives of Benzene and Anilines
Authors: WANG Gui‐Xiang , GONG Xue‐Dong , XIAO He‐Ming 
Published: August 2008

AbstractNitro derivatives of benzene and anilines were optimized to obtain their molecular geometries and electronic structures at a DFT‐B3LYP/6‐31G∗︁ level. Their IR spectra were obtained and assigned by vibrational analysis. Comparing the calculated IR spectra with these of experiments known, all the IR data obtained in this paper were considered to be reliable. Based on the frequencies scaled by 0.96 and the principle of statistic thermodynamics, the thermodynamic properties were evaluated, which were linearly related with the number of nitro and amino groups as well as the temperature, obviously showing good group additivity.
Taguchi Optimization for Combustion Synthesis of Aluminum Oxide Nano‐particles
Authors: EDRISSI Mohammad , NOROUZBEIGI Reza 
Published: August 2008

AbstractNano‐structured aluminum oxide powders were prepared by a combustion synthesis method utilizing serine as a new fuel. The product was sonicated to obtain nano powders. A Taguchi L‐4 statistical design of combustion synthesis was utilized to optimize the production of γ‐alumina powder. The product was characterized by XRD, BET, SEM, EDX and LLS. Nano crystalline γ‐alumina with crystal sizes between 4.26 and 5.47 nm and α‐Al2O3 powders with crystal sizes 24.51 and 28.62 nm were obtained by the combustion synthesis. The specific surface area was measured by a BET method to be 75.21 m2/g. The average particle size after sonication of product, observed by LLS, was 79.32 nm.
Synthesis, Structure and Biological Activities of Some Novel N‐(4,6‐Disubstituted‐pyrimidin‐2‐yl)‐N′‐(trifluoromethylphenyl)‐guanidine Derivatives
Authors: HE Feng‐Qi , LIU Xing‐Hai , WANG Bao‐Lei , LI Yong‐Hong , LI Zheng‐Ming 
Published: August 2008

AbstractA novel series of guanidine derivatives were designed, synthesized and confirmed by FTIR, MS, 1H NMR and elemental analysis. The single crystal structure of 11b was determined by X‐ray diffraction. Herbicidal activities of these guanidine derivatives were evaluated through barnyardgrass and rape cup tests, among which compounds 11a, 11b, and 11c against Brassica campestris reached 71.2%, 86.7%, and 86.9% at 100 µg·mL−1 respectively. The preliminary ketol‐acid reductoisomerase test showed that the synthesized compounds had weak activities.
Nicotinic acetylcholine receptor subunit mRNA expression in adult and developing rat medullary catecholamine neurons
Authors: O'Leary Kathryn T. , Loughlin Sandra E. , Chen Yiling , Leslie Frances M. 
Published: August 2008

AbstractNicotinic acetylcholine receptors (nAChRs) mediate numerous visceral functions via medullary catecholamine (CA) neurons found in the nucleus tractus solitarius (NTS), dorsal motor nucleus of the vagus (DMV), and ventrolateral medulla (VLM). However, the nAChR subtypes involved are not known. We have therefore characterized expression of nine nAChR subunit mRNAs in adult and developing rat medullary CA nuclei using combined isotopic/nonisotopic in situ hybridization. Tyrosine hydroxylase (TH) mRNA, the CA‐synthesizing enzyme, was used as a marker for CA neurons, because these nuclei consist of heterogeneous populations of cells. Subunit mRNA expression varied within and between nuclei, along the rostrocaudal axis, between cell types, and across development. All CA neurons expressed β2 mRNA, whereas α2 mRNA was completely absent. α6 And β3 mRNA expression were restricted mainly to the VLM. α4, α5, And α7 mRNA expression was significantly greater in the rostral than in the caudal VLM. α3 And β4 mRNAs were highly expressed in the dorsal region of the NTS, whereas dense α7 mRNA expression was restricted to the DMV and ventral NTS. The remaining subunit mRNAs were detected to some degree in both DMV and NTS. Except for α4 mRNA, which peaked prenatally, expression levels of subunit transcripts in the NTS and DMV were lower during development compared with adults. In the VLM, α3, α4, and α5 mRNAs expression peaked perinatally, whereas α6 and β3 levels increased with age. These variations in nAChR subunit mRNA expression suggest that different receptor subtypes may produce function‐specific regulation of medullary CA systems. J. Comp.

AbstractThe two main histological types of infiltrating breast cancer, lobular (ILC) and the more common ductal (IDC) carcinoma are morphologically and clinically distinct. To assess the molecular alterations associated with these breast cancer subtypes, we conducted a whole‐genome study of 166 archival estrogen receptor (ER)‐positive tumors (89 IDC and 77 ILC) using the Affymetrix GeneChip® Mapping 10K Array to identify sites of loss of heterozygosity (LOH) that either distinguished, or were shared by, the two phenotypes. We found single nucleotide polymorphisms (SNPs) of high‐frequency LOH (>50%) common to both ILC and IDC tumors predominately in 11q, 16q, and 17p. Overall, IDC had a slightly higher frequency of LOH events across the genome than ILC (fractional allelic loss = 0.186 and 0.156). By comparing the average frequency of LOH by chromosomal arm, we found IDC tumors with significantly (P < 0.05) higher frequency of LOH on 3p, 5q, 8p, 9p, 20p, and 20q than ILC tumors. We identified additional chromosomal arms differentiating the subtypes when tumors were stratified by tumor size, mitotic rate, or DNA content. Of 5,754 informative SNPs (>25% informativity), we identified 78 and 466 individual SNPs with a higher frequency of LOH (P < 0.05) in ILC and IDC tumors, respectively. Hierarchical clustering of these 544 SNPs grouped tumors into four major groups based on their patterns of LOH and retention of heterozygosity. LOH in chromosomal arms 8p and 5q was common in higher grade IDC tumors, whereas ILC and low‐grade IDC grouped together by virtue of LOH in 16q. Published 2008 Wiley‐Liss, Inc.
Breaking barriers and creating inclusiveness: Lessons of organizational transformation to advance women faculty in academic science and engineering
Authors: Bilimoria Diana , Joy Simy , Liang Xiangfen 
Published: August 2008

AbstractTo increase the representation and participation of women and other minorities in organizations, workplaces must become more inclusive. For such change to be successful and sustainable, organizations must systematically break down the barriers constraining women's participation and effectiveness; improve their prevailing structures, policies, and practices; and engender transformation in their climates. This article presents the experience of 19 U.S. universities, funded by the National Science Foundation's ADVANCE Institutional Transformation program, that have embraced comprehensive transformation for improved gender representation and inclusion in science and engineering disciplines. It describes the facilitating factors, program initiatives, institutionalization, and outcomes of their transformation, and suggests a transformation model that all organizations can use to create an inclusive and productive workplace for a diverse workforce. © 2008 Wiley Periodicals, Inc.
Time out for family: Shift work, fathers, and sports
Authors: Root Lawrence S. , Wooten Lynn Perry 
Published: August 2008

AbstractShift work is a fact of life for many workers. Almost one in six full‐time hourly and salary employees works a shift outside the 6 a.m. to 6 p.m. window that researchers use to define the temporal bounds of the traditional workday. Almost half of those working in restaurants and bars work such alternate shifts, as do more than a quarter of workers in hospitals and manufacturing facilities. Drawing on interviews and observations in a Midwestern auto parts plant, this study explores how individuals in this predominantly male workforce talk about fulfilling family responsibilities in the face of relatively inflexible shift schedules. Interviews and observations reveal how the time pressures of shift work, particularly the afternoon‐evening shift, affect the ability of fathers to participate in their children's activities, especially organized sports. Without formal options for scheduling flexibility, workers turn to a variety of informal approaches, such as ad hoc arrangements with sympathetic supervisors or the assistance of coworkers in covering for absences. In extreme cases, workers may engage in independent actions, often placing their jobs at risk. These findings contribute to the literature on work‐family conflict and the gender dynamics of work‐family life programs. By emphasizing the importance of including fathers in the work‐family equation, they have practical implications for both employers and policymakers concerned with addressing the challenges of helping a contemporary workforce strike an equitable balance between work and family life. © 2008 Wiley Periodicals, Inc.
Preliminary evaluation of the toxicity of some synthetic furan derivatives in two cell lines andArtemia salina
Authors: Amaro María I. , Monasterios Melina , Avendaño Milagros , Charris Jaime 
Published: August 2008

AbstractThis study describes the preliminary toxicity evaluation of five new furan derivatives, 2‐[2‐acetylamino‐2‐[(benzothiazolyl‐substituted)aminocarbonyl]vinyl]‐5‐nitro furane (compounds A, B, D and E) and 2‐[2‐phenylamino‐2‐[benzothiazolylaminocarbonyl]vinyl]furane (compound C). Cytotoxicity was determined using the MTT (tetrazolium salt) method over BHK21 (Syrian baby hamster kidney) and Hep‐2 (human larynx carcinoma) cells, which had previously been used to evaluate the cytotoxicity of the 5‐nitrofuran derivatives. The lethal concentration 50 (LC50) was determined using brine shrimp (Artemia salina) bioassay. Nitrofurantoin was used as reference compound. The results demonstrate that BHK21 cells are more sensitive than Hep‐2 cells. This structurally related serial of compounds shows a differential toxicity, which is an indication that the toxicity naturally arising from the nitro group can be modulated by the substituents over the furan ring. Additionally, compound C, the only derivative with no nitro group, was least toxic to Hep‐2, but exhibits toxicity to BHK21 cells and brine shrimp. The LC50brine shrimp test (BST) bioassay results were as follows: A, 654.2 µg ml−1; B, 50.0 µg ml−1; C, 533.4 µg ml−1; D, 172.1 µg ml−1; E, 76.4 µg ml−1, and NF, >1000 µg ml−1.

Published: August 2008

AbstractBackgroundVery long chain acyl coenzyme A (CoA) dehydrogenase (VLCAD) deficiency is a relatively common mitochondrial β‐oxidation disorder. The most severe form of VLCAD deficiency presents with neonatal cardiomyopathy and hepatic failure and is generally fatal within the first year of life. Mice deficient for long chain acyl CoA dehydrogenase (LCAD) closely resemble the clinical syndrome observed in VLCAD‐deficient humans. Recombinant adeno‐associated viral (rAAV) vectors with pseudotype capsids were investigated for their potential towards correcting the phenotype observed in mice heterozygous (+/−) for LCAD (i.e. liver and muscle steatosis).MethodsrAAV containing the mouse LCAD cDNA (mLCAD) under the transcriptional control of the CMV/chicken β‐actin hybrid promoter were injected intramuscularly into the tibialis anterior (TA) muscle of LCAD+/− mice or injected into the portal vein to transduce hepatocytes.ResultsTen weeks post‐injection of rAAV1‐mLCAD into the TA muscle, significantly increased levels of mLCAD within mitochondria were demonstrated by immunostaining of TA sections, immunoblotting of mitochondrial isolates and by the electron transfer flavoprotein (ETF) fluorescence reduction enzyme activity assay. Magnetic resonance spectroscopy of vector‐injected TA muscle demonstrated a reduction in the lipid content compared to phosphate‐buffered saline‐injected mice, whereas a systemic effect was observed as a reduction in liver macrosteatosis. Eight weeks after portal vein injection of rAAV8‐mLCAD into LCAD+/− mice, increased levels of mLCAD within hepatocyte mitochondria were demonstrated by immunostaining and also by the ETF assay. Scoring of the hepatosteatosis observed in partially deficient LCAD mice indicated a reduction in the lipid content within livers of vector‐treated mice.ConclusionsThese studies show that rAAV‐mediated delivery of mLCAD was efficient and led to an amelioration of local and systemic pathologies observed in partially deficient LCAD mice.

AbstractThe subtype distribution of 142 genotype 2 and 97 genotype 4 hepatitis C virus (HCV) isolates from the sera of 1,319 volunteer blood donors in France was determined by gene sequencing and by phylogenetic analysis of the NS5B region and E1 envelope. Findings underlined a wide range of subtypes in both genotypes, that is, 20 in HCV‐2 and 11 in HCV‐4. Eighteen of these 31 subtypes had not been defined previously. Some subtypes, that is, 2a, 2b, 2c, 2i, 2k, 4a, and 4d, showed numerous strains while subtypes in donors from West Africa or Central Africa showed an endemic profile with only a few strains. A Bayesian coalescence approach was used to estimate the demographic history of each HCV subtype. The estimated mean dates of the most recent common ancestors (MRCA) were 1,889 (confidence interval (CI), 1,842–1,930) for HCV‐2a, 1,886 (CI, 1,843–1,921) for HCV‐2b, 1,791 (CI, 1,699–1,848) for HCV‐2c, 1,846 (CI, 1,803–1,878) for HCV‐2i, 1,911 (CI, 1,879–1,937) for HCV‐4a, and 1,957 (CI, 1,943–1,967) for HCV‐4d. The period of spread for subtype 2b, 2c, and 2i was between 1900 and 1960 whereas rapid exponential spread for subtype 2a, 4a, and 4d occurred in the 1960s. The inferred histories of population growth indicated that transmission rates differed according to HCV subtype. These results may help to predict the future burden of HCV in France. J. Med.

Published: August 2008

AbstractThe presence of the ica loci and adhesins genes in clinical Staphylococcus aureus strains were considered important factors of virulence. In this study, 46 strains of Staphylococcus aureus were isolated from auricular infection, and were investigated for slime production using Congo Red Agar method (CRA). In order to detect the adhesins genes (ica A, ica D, fnb A, cna, Clf A) Polymerase Chain Reaction was used. Qualitative biofilm production of S. aureus using CRA plates revealed that 56.5% of strains were slime producers. In addition 78.26% of strains were ica A and ica D positive. While the fnbA gene was present in 76.1% of isolated strains. Furthermore, 56.5% of strains have the cna gene and 30.4% were clfA positives. Overall this study confirms the presence of fnb A and ica A/ica D genes in the majority of studies S. aureus strains isolated from Staphylococcal sepsis. (© 2008 WILEY‐VCH Verlag GmbH & Co.
