AbstractThe impact of screening by visual inspection with acetic acid (VIA), cytology or HPV testing on cervical cancer incidence and mortality is investigated in a cluster randomized controlled trial in India. We report findings after the screening phase, when 52 clusters, with a total of 142,701 women aged 30–59 years in Osmanabad District, India, were randomized into 4 arms for a single round of screening by trained midwives with either VIA, cytology or HPV testing as well as a control group. All laboratory tests were done locally. Test‐positive women underwent investigations (colposcopy/biopsy) and treatment in the base hospital. Data on participation, test positivity, positive predictive value and detection rates of cervical neoplasia were analyzed using cluster design methodology. Of the eligible women, 72–74% were screened. Test positivity rates were 14.0% for VIA, 7.0% for cytology and 10.3% for HPV. The detection rate of high‐grade lesions was similar in all intervention arms (0.7% for VIA, 1.0% for cytology and 0.9% for HPV testing) (p = 0.06, Mann‐Whitney test). While the detection rate for VIA dropped to 0.5% with declining test positivity during the course of the study, it remained constant for cytology and HPV testing. Over 85% of women with high‐grade lesions received treatment. Our results show that a high level of participation and good‐quality cytology can be achieved in low‐resource settings. VIA is a useful alternative but requires careful monitoring. Detection rates obtained by HPV testing were similar to cytology, despite higher investments. © 2005 Wiley‐Liss, Inc.
Analysis of job‐training effects on Korean women
Authors: Lee Myoung‐jae , Lee Sang‐jun 
Published: April 2005

AbstractWe analyse job‐training effects on Korean women for the period January 1999 to March 2000, using a large data set of size about 52,000. We employ a number of estimation techniques: Weibull MLE and accelerated failure time approach, which are both parametric; Cox partial likelihood estimator, which is semiparametric; and two pair‐matching estimators, which are in essence nonparametric. All of these methods gave the common conclusion that job training for Korean women increased their unemployment duration. The trainings were not cost‐effective in the sense that they took too much time ‘locking in’ the trainees during the training span, compared with the time they took to place the trainees afterwards. Despite this negative finding, some sub‐groups had positive effects: white‐collar workers trained for finance/insurance or information/communication. Copyright © 2005 John Wiley & Sons, Ltd.
I didn't tell, and I won't tell: dynamic response error in the SIPP
Authors: Bollinger Christopher R. , David Martin H. 
Published: April 2005

AbstractUsing state administrative records matched to the 1984 Survey of Income and Program Participation, we examine intertemporal relationships in response errors. False negative errors in reporting food stamps are highly correlated across interviews for the same household. Hypotheses that the error process can be explained by learning behaviour are not supported. Bivariate probit of response error in two periods reveals that responses to covariates are stable over time and the latent error terms are positively correlated. These findings support the hypothesis that respondents have a latent tendency to cooperate (or not cooperate) with surveys. Copyright © 2005 John Wiley & Sons, Ltd.
Translation of STO charge distributions
Authors: Fernández Rico J. , López R. , Ema I. , Ramírez G. 
Published: April 2005

AbstractBarnett and Coulson's ζ‐function method (M. P. Barnett and C. A. Coulson, Philos. Trans. R. Soc., Lond. A 1951, 243, 221) is one of the main sources of algorithms for the solution of multicenter integrals with Slater‐type orbitals. This method is extended here from single functions to two‐center charge distributions, which are expanded at a third center in terms of spherical harmonics times analytical radial factors. For s–s distributions, the radial factors are given by a series of factors corresponding to the translation of s‐type orbitals. For distributions with higher quantum numbers, they are obtained from those of the s–s distributions by recurrence. After analyzing the convergence of the series, a computational algorithm is proposed and its practical efficiency is tested in three‐center (AB|CC) repulsion integrals. In cases of large basis sets, the procedure yields about 12 correct significant figures with a computational cost of a few microseconds per integral. © 2005 Wiley Periodicals, Inc.

Edge‐face chromatic number and edge chromatic number of simple plane graphs
Authors: Luo Rong , Zhang Cun‐Quan 
Published: April 2005

AbstractGiven a simple plane graph G, an edge‐face k‐coloring of G is a function ϕ : E(G) ∪ F(G) →  {1,…,k} such that, for any two adjacent or incident elements a, b ∈ E(G) ∪ F(G), ϕ(a) ≠ ϕ(b). Let χe(G), χef(G), and Δ(G) denote the edge chromatic number, the edge‐face chromatic number, and the maximum degree of G, respectively. In this paper, we prove that χef(G) = χe(G) = Δ(G) for any 2‐connected simple plane graph G with Δ (G) ≥ 24. © 2005 Wiley Periodicals, Inc. J Graph Theory

Published: April 2005

AbstractThe purpose of this study is to evaluate the real‐world dose utilization of Dysport and BOTOX for cervical dystonia and blepharospasm. Six investigational sites (five countries) were identified. Investigators abstracted utilization data for patients who received Dysport before switching to BOTOX or BOTOX before switching to Dysport. Patients were identified during scheduled clinic visits and selected if they met study criteria, which included treatment for at least 2 consecutive years (at least 1 year with Dysport or BOTOX, then switched and maintained on BOTOX or Dysport for at least another year). A total of 114 patients were included in the assessment. Ratios of mean dose for Dysport to BOTOX ranged from a low of 2:1 to a high of 11:1. Thirty‐one percent of patients fell into the Dysport‐to‐BOTOX ratio grouping of 5:1 to less than 6:1; 30% of patients had a mean ratio of Dysport to BOTOX of 4:1 to less than 5:1; and only 21% of all patients evaluated fell into the Dysport‐to‐BOTOX ratio grouping of 3:1 to less than 4:1. Results are consistent with United Kingdom labeling for botulinum toxins stating that units of different serotype A toxins are not interchangeable and simple dose‐conversion factors are not applicable. © 2005 Movement Disorder Society
Novel movement disorder of the lower lip: Is it epilepsia partialis continua? Clues from a secondary case
Authors: Wali Gurusidheshwar M. 
Published: April 2005

AbstractA 28‐year‐old woman developed an acute‐onset novel movement disorder of the lower lip mimicking focal dystonia. Investigations showed it to be a presentation of epilepsia partialis continua occurring in association with agenesis of the corpus callosum. It responded favorably to anti‐epileptic drug therapy. Recently, Kleopa and Kyriakides1 reported on 4 patients who developed sudden‐onset movement disorder characterized by a tonic sustained, lateral and outward protrusion of half of the lower lip. They failed to find any causative factors, despite extensive investigation. Treatment with anticholinergics, clonazepam, and botulinum toxin injection failed to improve the movement disorder. I present an additional case of similar focal movement disorder occurring in the presence of agenesis of the corpus callosum. A scalp electroencephalogram revealed focal epileptic activity, and the movement disorder responded favorably to treatment with antiepileptic drugs. © 2005 Movement Disorder Society

Published: April 2005

AbstractThe pathological fibrillar deposits found in the heart and other organs of patients with senile systemic amyloidosis (SSA) and Swedish familial amyloidotic polyneuropathy (FAP) contain wild‐type (wt) and a mutant form of transthyretin (TTR), respectively. Previously, it was reported that these two forms of amyloid have different molecular features and it was thus postulated that the mechanism responsible for TTR fibrillogenesis in SSA and FAP may differ. To document further the nature of the amyloid in these entities, detailed morphological, histochemical, immunological, and structural analyses of specimens obtained from 14 individuals with SSA and 11 Swedish FAP patients have been performed. Two distinct patterns of amyloid deposition (designated A and B) were evident. In pattern A, found in all SSA and five of 11 FAP cases, the amyloid had a homogeneous but patchy distribution within the sub‐endocardium, sub‐epicardium, and myocardium; exhibited weak congophilia and green birefringence; and was composed of tightly packed, short, unorientated fibrils. This material contained mainly ∼79‐residue C‐terminal fragments of the amyloidogenic precursor protein. In pattern B, seen in the six other FAP patients, the amyloid appeared as thin streaks throughout the cardiac tissue; often surrounded individual muscle cells; was strongly congophilic and birefringent; had long fibrils arranged in parallel bundles, often penetrating into myocytes; and was composed of virtually intact TTR molecules. These findings provide substantive evidence for the morphological and structural heterogeneity of TTR fibrils and suggest that the two types of deposition may reflect fundamental differences in the pathogenesis of the TTR‐associated amyloidoses.

Randomized comparison of antibiotics with and without granulocyte colony‐stimulating factor in children with chemotherapy‐induced febrile neutropenia: A report from the Children's Oncology Group
Authors: Özkaynak M. Fevzi , Krailo Mark , Chen Zhengjia , Feusner James 
Published: April 2005

AbstractPurposeTo determine if granulocyte colony‐stimulating factor (G‐CSF) with empirical antibiotics accelerates febrile neutropenia resolution compared with antibiotics without it.Patients and MethodsEligible children were treated without prophylactic G‐CSF and presented with fever (temperature >38.3°C) and neutropenia afterward. Patients with acute myelogenous leukemia and myelodysplastic syndrome were excluded. Assignments were randomized between G‐CSF (5 μg/kg/day) or none beginning within 24 hr of antibiotics. Subcutaneous administration was recommended, but intravenous G‐CSF was allowed. Patients remained on study until absolute neutrophil count (ANC) >500/μl and ≥48 hr without fever.ResultsOne of 67 patients enrolled was ineligible, 59 had acute lymphoblastic leukemia (ALL). Thirty‐four were assigned to antibiotics, 32 to G‐CSF plus antibiotics. Adding G‐CSF significantly reduced neutropenia and febrile neutropenia recovery times. Median days to febrile neutropenia resolution was nine earlier with G‐CSF (4 vs. 13 days) (P < 0.0001). However, there was no difference in the resolution of fever between arms. Hospitalization median was shorter by 1 day with G‐CSF (4 vs. 5 days) (P = 0.04). There was no difference in the duration of IV and oral antibiotic treatment, addition of antifungal therapy, and shock incidence. A trend for decreased incidence of late fever with G‐CSF was noted (6.3 vs. 23.5%) (P = 0.08).ConclusionsAdding G‐CSF to empiric antibiotic coverage accelerates chemotherapy‐induced febrile neutropenia resolution by 9 days in pediatric patients, mainly with ALL, which results in a small but significant difference in the median length of hospitalization. © 2005 Wiley‐Liss, Inc.
Symptoms of post‐traumatic stress in children with cancer and their parents: Effects of informant and time from diagnosis
Authors: Phipps Sean , Long Alanna , Hudson Melissa , Rai Shesh N. 
Published: April 2005

AbstractBackgroundPost‐traumatic stress disorder (PTSD) has been put forth as a model for understanding the adjustment of children with cancer and their parents, but findings in the literature regarding the prevalence of post‐traumatic stress symptoms (PTSS) have been mixed. This study examined PTSS levels in both patients and parents as a function of time elapsed from diagnosis, and by use of parent versus child reports for assessing patient PTSS.ProcedureFour groups of patients (total N = 162) differing in time elapsed since diagnosis were assessed with standardized measures of PTSS. Patients reported on their own symptoms, while parents reported on their symptoms as well as symptoms in their child.ResultsSignificant differences between groups were observed on all patient PTSS measures. Recently diagnosed patients obtained higher PTSS scores than survivors more than 5 years from diagnosis. Likewise, parents of recently diagnosed patients self‐reported significantly higher levels of PTSS than parents of long‐term survivors. Parent–child correlations were high and no differences were observed between parent and patient report of patient PTSS. Comparison with historical control data suggests that levels of PTSS in patients are very low.ConclusionConcordance between parent and child reports of child PTSS suggests that data may be obtained with reasonable confidence from either if only one informant is available. Higher levels of PTSS in patients who are recently diagnosed (and their parents) in comparison to long‐term survivors, suggest that the symptoms reported reflect primarily a concurrent response to ongoing acute stressors, rather than a post‐traumatic re‐experiencing of past traumas. This, in combination with the low levels of patient PTSS raise questions regarding the utility of PTSD as a model for understanding patient and parent adjustment to childhood cancer. © 2005 Wiley‐Liss, Inc.
Clotting times and tensile properties of insoluble silk fibroin films containing heparin
Authors: Lv Qiang , Cao Chuanbao , Zhu Hesun 
Published: April 2005

AbstractAlthough many novel approaches for producing small‐caliber arterial grafts have been developed, problems with mechanical properties and blood compatibility have up to now prevented clinical implementation. Blending anticoagulant agents with natural biomaterials having excellent cell attachment and growth properties, and making the release time of anticoagulant agents exceed the time required by endothelial tissue regeneration, might be a novel method to prepare appropriate biomaterials used in small‐diameter arterial grafts. In this article, an insoluble fibroin film, having excellent blood compatibility and mechanical properties, was obtained by blending with heparin. The structural properties of the films were examined through Fourier‐transform infrared attenuated total reflectance (FTIR‐ATR) and X‐ray diffraction (XRD). The results indicated that plentiful β‐sheet crystals existed in fibroin films containing heparin. The tensile strength and elongation at break of film containing heparin were, respectively, 10.3 MPa and 54 % in the wet state, which can satisfy the mechanical requirements of blood‐contacting materials such as small‐diameter tubing. The clot times [activated partial thromboplastin time (APTT), thrombin time (TT) and prothrombin time (PT)] all exceeded the measurement limit of the clot detection instrument. Even the APTT and TT of film immersed in water for 28 days exceeded the measurement limit of the clot detection instrument. The in vitro culture of endothelial cells on the film was also investigated, and the result indicated that cells can grow to cover all of the available surface area of the film within 8 days. Fibroin films containing heparin could retain blood compatibility for 28 days, which means that this is a promising material for small‐diameter artery applications.

Published: April 2005

AbstractIn this article, we discuss the history behind efforts to transfer school psychology research into practice and review the literature pertaining to treatment acceptability, participatory action research, organizational change, and generalization programming. We then present a model for the systematic programming of this transfer and propose a three‐step framework that emphasizes multiple conceptual bases to transfer research into practice. This three‐step framework includes creating usable knowledge, transferring usable knowledge, and supporting usable knowledge. It is our intention that the proposed framework will provide a starting point that can be informed by researchers and practitioners in the field of school psychology. We conclude with examples of our research efforts to systematically study the transfer of research into practice. © 2005 Wiley Periodicals, Inc. Psychol Schs 42: 459–473, 2005.
Synthesis and photophysical properties of polyfluorenes bearing silicon‐based functional groups
Authors: Takagi Koji , Kunii Satoshi , Yuki Yasuo 
Published: April 2005

AbstractFive polyfluorenes bearing bulky trimethylsilyl (PTMS1 and PTMS2), tris(trimethylsilyl)silyl (PTTMS1), and silsesquioxane groups (PPOSS1 and PPOSS2) were synthesized through palladium‐catalyzed Suzuki coupling reactions. In the solution state, every polymer showed comparable ultraviolet–visible spectra, and they emitted blue light with high quantum efficiency. In the solid state, however, three trimethylsilyl‐functionalized polyfluorenes indicated redshifts of the fluorescence peak. In particular, PTMS1 and PTTMS1, having a hydrogen at the C‐9 position of fluorene, also showed green‐light emissions. After the annealing of the spin‐coated films, the blue‐emissive peak decreased and the green‐emissive peak became stronger in the photoluminescence spectra of three trimethylsilyl‐functionalized polyfluorenes. In contrast, PPOSS2 showed a pure blue‐light emission in the film state and even after the thermal treatment, which could be accomplished by the encapsulation of the polymer chains by the large polyhedral oligomeric silsesquioxane molecule. © 2005 Wiley Periodicals, Inc.

Effect of incorporated CdS nanoparticles on the crystallinity and morphology of poly(styrene‐b‐ethylene oxide) diblock copolymers

Published: April 2005

AbstractSurface‐modified CdS nanoparticles selectively dispersed in hexagonally packed poly(ethylene oxide) (PEO) cylinders of poly(styrene‐b‐ethylene oxide) (PSEO) block copolymers were prepared. The photoluminescence and ultraviolet–visible characteristics of the presynthesized CdS nanoparticles inN,N‐dimethylformamide and in PEO domains of the PSEO block copolymers were determined. Because of strong interactions between the CdS nanoparticles and PEO chains, as shown by Fourier transform infrared spectroscopy, the incorporation of the CdS nanoparticles prevented the PEO cylinders from properly crystallizing; this was confirmed by differential scanning calorimetry and wide‐angle X‐ray diffraction measurements. The intercylinder distance between the swollen and reduced‐crystallinity CdS/PEO cylinders in turn increased, as confirmed by small‐angle X‐ray scattering and transmission electron microscopy. At a high CdS concentration (43 wt % or 8.3 vol % with respect to PEO), however, the hexagonally packed cylindrical nanostructure of the PSEO diblock copolymers was destroyed. © 2005 Wiley Periodicals, Inc.

Impedance spectroscopy studies on Ga‐ion‐modified PLZT ceramics

Published: April 2005

AbstractPolycrystalline samples of [Pb0.92(La1–zGaz)0.08][Zr0.65Ti0.35]0.98O3 (PLGZT) for z = 0.0, 0.3, 0.6, 0.9, and 1.0 were prepared by a solid‐state reaction technique. The single‐phase formation of the new compounds with tetragonal crystal structures was established by the room‐temperature X‐ray analysis. The occupancy of Ga ion in the La site has been confirmed by FTIR analysis. Complex impedance spectroscopy (CIS) has provided a convincing evidence for the existence of both grain (bulk) and grain boundary effects in the materials, which is also evident from the microstructures, comprise grains separated by well‐defined boundaries. The electrical processes in the sample have been modeled in the form of an electrical equivalent circuit made up of a series combination of two parallel RC circuits attributed to grains and grain boundaries. The real and imaginary parts of dielectric constants have been separated from impedance spectrum results and expressed in terms of loss tangent (tan δ). The ferroelectric transition temperature (Tc) of the materials is evaluated from the plot of real permittivity versus temperature and found to be shifted to higher temperature side with increasing Ga‐ion concentration. A sharp rise in conductivity is observed in the nature of temperature variation of the bulk electrical conductivity (σdc) at higher temperature for all the Ga‐modified PLZT samples. This type of behavior is typical to dielectric ceramics having conductive grain boundary arising out of a relaxation process of the Maxwell–Wagner type. At higher temperature a substantial increase in conductivity ∼10–3 S cm–1 is achieved for complete replacement of the La ion by Ga (z = 1.0). (© 2005 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
Relevance of phosphorus incorporation and hydrogen removal for Si:P δ‐doped layers fabricated using phosphine
Authors: Goh K. E. J. , Oberbeck L. , Simmons M. Y. 
Published: April 2005

AbstractWe present a study to determine the importance of phosphorus incorporation and hydrogen removal for the electrical activation of phosphorus dopants in Si:P δ‐doped samples fabricated using phosphine dosing and molecular beam epitaxy (MBE). The carrier densities in these samples were determined from Hall effect measurements at 4 K sample temperature. An anneal to incorporate phosphorus atoms into substitutional lattice sites is critical to achieving full dopant activation after Si encapsulation by MBE. Whilst the presence of hydrogen can degrade the quality of the Si encapsulation layer, we show that it does not adversely impact the electrical activation of the phosphorus dopants. We discuss the relevance of our results to the fabrication of nano‐scale Si:P devices. (© 2005 WILEY‐VCH Verlag GmbH & C o. KGaA, Weinheim)
