Examination of the frequency modulation and lifting techniques for the generalized power factor correction switched‐capacitor resonant converter
Authors: Law K. K. , Cheng K. W. Eric 
Published: November 2007

AbstractA generalized method for switched‐capacitor resonant converter for use in power factor correction is proposed. Using the techniques, the voltage conversion can be generated into step‐up, step‐down and inverting. The requirement of the inductance in the circuit is minimal. The quality of the power factor improvement is substantial. The method used in the converter includes the frequency modulation and lifting techniques. The power factor improvement is significant and the circuit concept is simple. Mathematical analysis and experimental confirmation have been presented to demonstrate the novel idea.

Published: November 2007

AbstractObjective:To examine trends in weight control practices from 1995 to 2005.Method:The Youth Risk Behavior Surveillance System biennially assesses five weight control behaviors among nationally representative samples of United States high school students.Results:Across time, more females than males dieted (53.8% vs. 23.8%), used diet products (10% vs. 4.3%), purged (7.5% vs. 2.7%), exercised (66.5% vs. 46.9%), or vigorously exercised (42.8% vs. 36.8%). All weight control behaviors among males increased during the decade. Black females were less likely than Hispanic females, who were less likely than White females, to practice weight control. White males were less likely than Black males, who were less likely than Hispanic males, to practice weight control. The ethnic difference in weight control practices is consistent across time.Conclusion:All male adolescents are at increasing risk for developing eating disorder symptomatology, and Black females appear to continue to resist pressure to pursue thinness. © 2007 by Wiley Periodicals, Inc.

The influence of reported trauma and adverse events on eating disturbance in young adults
Authors: Smyth Joshua M. , Heron Kristin E. , Wonderlich Stephen A. , Crosby Ross D. , Thompson Kevin M. 
Published: November 2007

AbstractObjective:Early experiences of trauma or adverse events may be associated with eating disturbance later in life, but evidence is scarce. This study examined whether reported history of adverse life events predicted eating disturbance upon college entry and prospective changes over the first semester of college.Method:First semester college students (n = 249) reported trauma/adverse event histories and completed disordered eating questions (with two factors, restriction and binging/purging) at the beginning and end of their first semester.Results:At college entry, trauma type, frequency, and overall trauma severity were related to restricted eating, and trauma type and severity was related to binging/purging. Prospective increases in reported restricted eating were predicted by trauma type. Prospective increases in binging/purging were associated with trauma type and total trauma severity.Conclusion:These data suggest that reports of past trauma and adverse events cross‐sectionally predict reported disordered eating at college entry as well as prospective increases in disordered eating over the first semester of college. Research and clinical implications for these findings are discussed. © 2007 by Wiley Periodicals, Inc. Int J Eat Disord 2008

AbstractThe direct protonation of the bridging hydroxo ligands in [Rh(μ‐OH)(cod)]2 by 1,1‐dimercaptocyclohexane [Chxn(SH)2] yields the gem‐dithiolato‐bridged compound [Rh2(μ‐S2Chxn)(cod)2] (1). The dinuclear framework in 1 is supported by a 1,1‐cyclohexanedithiolato ligand exhibiting a 1:2κ2S,1:2κ2S′ coordination mode. Compound 1 is an active catalyst precursor in the presence of P‐donor ligands for the hydroformylation of oct‐1‐ene under mild conditions of pressure and temperature (100 PSI, 353 K). The best results were obtained with phosphite ligands as modifying ligands. An aldehyde selectivity of 97 %, a regioselectivity towards the linear aldehyde of 81 %, and turnover frequencies of up to 198 h–1 were obtained with the catalytic system 1/P(OMe)3. The dinuclear compound [Rh2(μ‐S2Chxn)(CO)2(PPh3)2] (2) was isolated from the catalytic solutions resulting from the system 1/PPh3 and was characterized by spectroscopic means and by X‐ray diffraction to be the trans isomer. The mixed‐ligand dinuclear complexes 2 and [Rh2(μ‐S2Chxn)(CO)2(PCy3)2] (3) (Cy = cyclohexyl) were independently prepared by reaction of Chxn(SH)2 with the mononuclear complexes [Rh(acac)(CO)(PR3)] in the appropriate molar ratio.(© Wiley‐VCH Verlag GmbH & Co.

New Approaches Towards Monoamino Polyglycerol Dendrons and Dendritic Triblock Amphiphiles
Authors: Wyszogrodzka Monika , Möws Katrin , Kamlage Stefan , Wodzińska Joanna , Plietker Bernd , Haag Rainer 
Published: November 2007

AbstractIn order to improve the water solubility of nonpolar compounds such as drugs or dyes, new amphiphilic molecules are needed. In this paper we describe a new class of triblock amphiphiles that we have synthesized by a straightforward convergent approach. These amphiphiles each consist of a nonpolar biphenyl core and a polar shell based on various generations of monoamino polyglycerol dendrons, coupled to the core through amide linkages (1). For the synthesis of these monoamino dendrons we applied a simple iterative two‐step process based on allylation of an alcohol group and catalytic dihydroxylation. As starting materials, D,L‐serine/serinol and – in a second, similar pathway – commercially available triglycerol were used. The transport behavior of these defined triblock amphiphiles was then investigated with the nonpolar dye Nile Red in water.(© Wiley‐VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2008)

Comparing strategies for modeling tree diameter percentiles from remeasured plots
Authors: Mehtätalo Lauri , Gregoire Timothy G. , Burkhart Harold E. 
Published: November 2007

AbstractIn many situations, including forest management planning, the underlying diameter distribution of a forest stand needs to be predicted. One alternative for predicting diameter distribution involves modeling diameter percentiles. We introduce a quantile regression (QR) approach for predicting diameter percentiles, and compare it with customary linear fixed‐effect and linear mixed‐effects models. The customary methods involve first estimating plot‐specific sample percentiles and then regressing them on stand characteristics, whereas QR directly models percentiles. We compared two prediction situations: a conditional one where a previously measured diameter sample is available from the stand of interest, and a marginal one where only some stand‐specific characteristics are known. To compare the predictions to the true underlying percentiles, we conducted a simulation study. The QR approach led to slight improvements in the marginal prediction situation. In the conditional situation, the mixed‐effect model led to clearly better predictions and should be preferred until QR methods have been developed for hierarchical data. It is extremely important to filter out the highly correlated sampling error from conditional predictions in order that the models predict underlying population percentiles rather than the realized sample percentiles.

Third‐order Cartesian overset mesh adaptation method for solving steady compressible flows
Authors: Saunier O. , Benoit C. , Jeanfaivre G. , Lerat A. 
Published: November 2007

AbstractA third‐order mesh generation and adaptation method is presented for solving the steady compressible Euler equations. For interior points, a third‐order scheme is used on Cartesian and curvilinear meshes. Concerning the mesh adaptation, the method of Meakin is also extended to third order. The accuracy of the new overset mesh adaptation method is demonstrated by a grid convergence study for 2‐D inviscid model problems and results are compared with a second‐order method. Finally, the method is applied to the computation of an inviscid 3‐D flow around a hovering blade of the ONERA 7A helicopter rotor exhibiting an improvement in the wake capture. With a 7 million point mesh, the tip vortex can be followed for more than three rotor revolutions with the third‐order method. The CPU time needed for this calculation is only 3% higher than with a conventional second‐order method. Copyright © 2007 John Wiley & Sons, Ltd.
Testing mean reversion in financial market volatility: Evidence from S&P 500 index futures
Authors: Bali Turan G. , Demirtas K. Ozgur 
Published: November 2007

AbstractThis article presents a comprehensive study of continuous time GARCH (generalized autoregressive conditional heteroskedastic) modeling with the thintailed normal and the fat‐tailed Student's‐t and generalized error distributions (GED). The study measures the degree of mean reversion in financial market volatility based on the relationship between discrete‐time GARCH and continuoustime diffusion models. The convergence results based on the aforementioned distribution functions are shown to have similar implications for testing mean reversion in stochastic volatility. Alternative models are compared in terms of their ability to capture mean‐reverting behavior of futures market volatility. The empirical evidence obtained from the S&P 500 index futures indicates that the conditional variance, log‐variance, and standard deviation of futures returns are pulled back to some long‐run average level over time. The study also compares the performance of alternative GARCH models with normal, Student's‐ t, and GED density in terms of their power to predict one‐day‐ahead realized volatility of index futures returns and provides some implications for pricing futures options. © 2008 Wiley Periodicals, Inc.

Forecasting oil price movements: Exploiting the information in the futures market
Authors: Coppola Andrea 
Published: November 2007

AbstractRelying on the cost of carry model, the long‐run relationship between spot and futures prices is investigated and the information implied in these cointegrating relationships is used to forecast out of sample oil spot and futures price movements. To forecast oil price movements, a vector error correction model (VECM) is employed, where the deviations from the long‐run relationships between spot and futures prices constitute the equilibrium error. To evaluate forecasting performance, the random walk model (RWM) is used as a benchmark. It was found that (a) in‐sample, the information in the futures market can explain a sizable portion of oil price movements; and (b) out‐of‐sample, the VECM outperforms the RWM in forecasting price movements of 1‐month futures contracts. © 2008 Wiley Periodicals, Inc.

Determinants of Japanese Yen interest rate swap spreads: Evidence from a smooth transition vector autoregressive model
Authors: Huang Ying , Chen Carl R. , Camacho Maximo 
Published: November 2007

AbstractThis study investigates the determinants of variations in the yield spreads between Japanese yen interest rate swaps and Japan government bonds for a period from 1997 to 2005. A smooth transition vector autoregressive (STVAR) model and generalized impulse response functions are used to analyze the impact of various economic shocks on swap spreads. The volatility based on a GARCH (generalized autoregressive conditional heteroskedasticity) model of the government bond rate is identified as the transition variable that controls the smooth transition from a high volatility regime to a low volatility regime. The break point of the regime shift occurs around the end of the Japanese banking crisis. The impact of economic shocks on swap spreads varies across the maturity of swap spreads as well as regimes. Overall, swap spreads are more responsive to the economic shocks in the high volatility regime. Moreover, a volatility shock has profound effects on shorter maturity spreads, whereas the term structure shock plays an important role in impacting longer maturity spreads. Results of this study also show noticeable differences between the nonlinear and linear impulse response functions. © 2008 Wiley Periodicals, Inc. Jrl Fut Mark 28:82–107, 2008

Published: November 2007

AbstractBackgroundSmall interfering RNAs (siRNAs) can induce specific gene silencing through cytoplasmic mRNA cleavage and nuclear transcriptional silencing, necessitating delivery to different cellular compartments. This study presents a reducible copolypeptide (rCPP) carrier containing different molar ratios of a histidine‐rich peptide (HRP) and nuclear localization sequence (NLS) peptide to modulate intracellular trafficking of transfected siRNA and primary RNA transcripts (pri‐miRNA).MethodsPolyplex formation using siRNA and rCPP was demonstrated using photon correlation spectroscopy and atomic force microscopy. Confocal and fluorescence microscopy were used to investigate cellular uptake and nuclear trafficking whilst endogenous enhanced green fluorescent protein (EGFP) knockdown in H1299 cells was evaluated using flow cytometry. Transcriptional gene silencing of endogenous EF1A was verified using real‐time reverse‐transcription polymerase chain reaction (RT‐PCR) and pri‐miRNA nuclear processing was demonstrated using Northern analysis.ResultsrCPP‐based polyplexes showed rapid cellular uptake and low cytotoxicity. Labelled components revealed intact polyplexes after 2 h that exhibited directed movements consistent with endosomal trafficking. Polyplex‐mediated knockdown of EGFP increased with greater HRP content. The inclusion of NLS promoted nuclear localization of transfected siRNAs and pri‐miRNAs to the nuclear compartment allowing for transcriptional silencing of EF1A and Drosha and Dicer dependent expression of mature miRNA, respectively.ConclusionOur results demonstrate that reducible copolypeptides can be used as carriers for the non‐toxic cellular delivery of siRNA and pri‐miRNA. The nuclear targeting of rCPPs can be utilized for delivery of siRNAs and pri‐miRNAs to the nuclear compartment for transcriptional gene silencing or endogenous processing into mature miRNA, respectively, which could potentially lead to improved therapeutic approaches.

The role of other orientation in organizational citizenship behavior
Authors: Lester Scott W. , Meglino Bruce M. , Korsgaard M. Audrey 
Published: November 2007

AbstractThis article draws on social exchange theory and the theory of other orientation to examine how job satisfaction and individual differences are related to organizational citizenship behavior (OCB). Previous research specifying a direct effect for individual differences on OCB has yielded disappointing results. In contrast, this study examines the moderating role of individual differences in the relationship between job satisfaction and OCB. As hypothesized, results show a weaker relationship between job satisfaction and OCB for persons who are higher in other orientation. We discuss the theoretical implications of this finding and directions for future research. Copyright © 2007 John Wiley & Sons, Ltd.
