Neighborhood immigrant concentration, acculturation, and cultural alienation in former soviet immigrant women
Authors: Miller Arlene Michaels , Birman Dina , Zenk Shannon , Wang Edward , Sorokin Olga , Connor Jorgia 
Published: December 2008

AbstractSeveral acculturation theories note the importance of surrounding context, but few studies describe neighborhood influences on immigrant adaptation. The purpose of this study was to examine relationships among neighborhood immigrant concentration, acculturation, and alienation for 151 women aged 44–80 from the former Soviet Union who lived in the US fewer than 13 years. Participants resided in 65 census tracts in the Chicago area with varying concentrations of Russian‐speaking and diverse immigrants. Results from self‐report questionnaires suggest that the effect of acculturation on alienation varies depending on neighborhood characteristics. The study also demonstrates the complexity of individual and contextual influences on immigrant adoption. Understanding these relationships is important for developing community‐based and neighborhood‐level interventions to enhance the mental health of immigrants. © 2008 Wiley Periodicals, Inc.

Published: December 2008

AbstractInhibition of epidermal growth factor receptor tyrosine kinase (EGFR‐TK) has emerged as a major approach for cancer‐targeted therapy. Consequently, there has been a great interest in the use of labeled EGFR‐TK inhibitors as positron emission tomography (PET) imaging agents. Currently, the developed agents did not yield adequate PET imaging of animal models probably due to poor solubility, rapid washout from blood, and low stability in vivo. In order to overcome these hurdles, new derivatives of previously reported inhibitors (ML04, 2) with decreased log P and increased solubility were designed and synthesized. These compounds (3–5) exhibited high autophosphorylation inhibitory potency with an IC50 of 5–35 nM, decreased log P's (3.1, 3.34, and 3.45, respectively), and significantly increased solubility (630, 300, and 120 µg/mL, respectively) relative to the previously reported parent compound 2 (log P=3.7, solubility=3.5 µg/mL). The labeling of compound 5 with [18F] and compounds 3 and 4 with [11C] and [124I], respectively, involved a one‐step radiosynthesis. Compounds 3–5 were obtained with a total decay‐corrected radiochemical yields of 13, 31, and 5%, respectively, and were found to be stable in blood. The positive outcome achieved with compounds 3–5 merits further in vivo evaluation as PET bioprobes. Copyright © 2008 John Wiley & Sons, Ltd.

Hip transposition as a universal surgical procedure for periacetabular tumors of the pelvis
Authors: Gebert Carsten , Gosheger Georg , Winkelmann Winfried 
Published: December 2008

AbstractSurgical treatment of pelvic tumors represents one of the most challenging problems in musculoskeletal oncology, especially in the periacetabular region. Because of the complex anatomy and demanding biomechanical situation, surgery leads to a considerable disability while all possible types of reconstruction are often associated with high complication rates. Nevertheless, it is known that wide resection of the tumor is one of the key points for long‐term survival in sarcoma therapy. Therefore, hip transposition was established in our clinic as a universal tool for periacetabular tumors excelling in small foreign parts and resulting in acceptable complication rates with good functional outcome. The following article gives an overview of the technique and the indications of different types of hip transposition, which were developed from the first procedure, described and published by Winkelmann in 1988.

On the same page: The value of paid and volunteer leaders sharing mental models in churches
Authors: Solansky Stephanie T. , Duchon Dennis , Plowman Donde Ashmos , Martínez Patricia G. 
Published: December 2008

AbstractWe examine the idea that mental models shared among paid and volunteer leaders are associated with improved financial performance in nonprofit organizations. Our empirical analysis of thirty‐seven churches yields evidence that organizations are more effective if paid and volunteer leaders have a shared task mental model—that is, if they report similar conceptualizations of organizational goals and decision‐making processes. These findings suggest that the extent of leaders' agreement on organizational goals and the processes of how decisions are made matter for organizational performance. We argue that it is as important to ensure that everyone is on the same page with regard to goals and how decisions are made as it is to have the “right” goals or right decision processes in place. Implications for practice and future research on shared mental models are discussed.
Getting to yes … or no: Nonprofit decision making and interorganizational restructuring
Authors: Campbell David A. 
Published: December 2008

AbstractThis article explores the decision‐making process nonprofit organizations use to determine whether to pursue merger or other forms of interorganizational restructuring. The research uses a case study design, analyzing four examples of interorganizational restructuring. The findings describe both the structure and the characteristics of the processes used in four cases. The research found that the decision‐making processes used in the four cases had several core elements. Participants in restructuring customized decision‐making processes to meet their needs, and power dynamics shaped those processes. Findings about the characteristics of the process emphasize the importance of communication and trust. How partners used power affected the decision‐making process and had implications for postmerger success. Decision‐making processes for cases involving two partners exhibited characteristics that were different from those involving multiple partners. Future research should consider the role of trust in restructuring decisions and the responsibilities of board and staff in the restructuring assessment process.
Where you stand depends on where you sit: Participation and reactions to change
Authors: Basinger Nancy Winemiller , Peterson Jessica Romine 
Published: December 2008

AbstractAlthough a considerable body of research on strategic planning, organizational decision making, and organizational change has emphasized the importance of participation by key stakeholders for the successful management of organizational change, few empirical studies have produced in‐depth understanding of the differing perspectives of stakeholder groups according to their level of involvement in decisions about major change. This case study examines the differing perspectives and perceptions of stakeholders leading into and during the merger of two nonprofit arts organizations. It refines and enriches existing empirical research on the effects of participation on the implementation of change.
On comparison of the solutions for an axisymmetric flow
Authors: Hayat T. , Ahmad I. , Javed T. 
Published: December 2008

AbstractRecently, Ariel (Comput Math Appl, 54 (2007), 1169–1183) explored the axially stretching flow of a viscous fluid in the presence of a velocity slip. He computed the solutions by noniterative technique, the homotopy perturbation method (HPM), and the perturbation and asymptotic methods (for small and large values of the slip parameter, respectively). Through comparison between these solutions, he claimed that HPM solution is the best solution showing close agreement with an exact solution. Here, we recomputed the flow problem considered in Ariel's work for the series solution by homotopy analysis method (HAM). It is found that HAM solution is identical with the presented exact solution in Ariel's work. Furthermore, the HAM solution is better than the HPM solution. © 2008 Wiley Periodicals, Inc.

Maximum norm error bounds of ADI and compact ADI methods for solving parabolic equations
Authors: Liao Hong‐Lin , Sun Zhi‐Zhong 
Published: December 2008

AbstractAlternating direction implicit (ADI) schemes are computationally efficient and widely utilized for numerical approximation of the multidimensional parabolic equations. By using the discrete energy method, it is shown that the ADI solution is unconditionally convergent with the convergence order of two in the maximum norm. Considering an asymptotic expansion of the difference solution, we obtain a fourth‐order, in both time and space, approximation by one Richardson extrapolation. Extension of our technique to the higher‐order compact ADI schemes also yields the maximum norm error estimate of the discrete solution. And by one extrapolation, we obtain a sixth order accurate approximation when the time step is proportional to the squares of the spatial size. An numerical example is presented to support our theoretical results. © 2008 Wiley Periodicals, Inc. Numer Methods Partial Differential Eq 2010
Modeling of complex parison formation in extrusion blow molding: Effect of medium to large die heads and fuel tank geometry
Authors: Yousefi Azizeh‐Mitra , Atsbha Haile 
Published: December 2008

AbstractThis work presents the effect of die geometry and die gap opening on the extrudate swell phenomenon, in complex parison formation using the vertical wall distribution system (VWDS) and partial wall distribution system (PWDS). The BlowParison© software from IMI is used to predict the parison formation for a combined VWDS/PWDS system, accounting for swell, sag, and nonisothermal effects. This software couples a fluid mechanics approach to represent the die flow, with a solid mechanics approach to represent the parison behavior outside the die, and a mathematical swell model to account for the pronounced elongational and shear stresses at high Weissenberg numbers. The emphasis is placed on experimental validation of the predicted parison dimensions using four diverging die geometries and different sets of VWDS/PWDS profiles. The experimental and predicted weight profiles for a dissected fuel tank are also presented. Both experimental and simulation results suggest a strong dependence of extrudate swell to the die geometry in the die land zone. The results also demonstrate the validity of the numerical predictions for part design purposes given the multitude of experimental validations presented in this work. POLYM. ENG. SCI., 2009.

Pea starch‐based composite films with pea hull fibers and pea hull fiber‐derived nanowhiskers
Authors: Chen Yun , Liu Changhua , Chang Peter R. , Anderson Debbie P. , Huneault Michel A. 
Published: December 2008

AbstractNew applications of both pea hull fiber (PHF) and PHF‐derived nanowhiskers (PHFNW), isolated from PHF by acid‐hydrolysis, as fillers in starch‐based biocomposite films were explored in this work. Two series of films were prepared by blending pea starch (PS), respectively, with PHF and PHFNW. The effects of PHF and PHFNW as filler on the structure and properties of the composite films were comparatively investigated by observation of morphology and analysis of thermal, optical, and mechanical properties. The results revealed that the PS/PHFNW nanocomposite films exhibited improved physical properties over both the neat PS film and PS/PHF microcomposite films. The light transmittance at 800 nm, tensile strength, elongation at break, and Young's modulus were 56.0%, 4.1 MPa (Megapascal), 30.1%, 40.3 MPa, respectively, for the PS film without filler; 58.0%, 7.6 MPa, 41.8%, and 415.2 MPa for the PS/PHFNW film containing 10 wt% filler; and 37.2%, 2.8 MPa, 17.0%, and 29.8 MPa for the PS/PHF film containing 10 wt% filler. The improvement to the properties of PS/PHFNW nanocomposite films may be attributed to the nanometer size effect of PHFNW, which resulted in the homogeneous dispersion of PHFNW within the PS, and the strong interactions between the matrix and the nanoscale filler.

Cavitation bubble dynamics in non‐Newtonian fluids
Authors: Brujan Emil‐Alexandru 
Published: December 2008

AbstractCavitation phenomena play important roles in many areas of science and engineering. The most interesting effect of the non‐Newtonian properties of the liquid is the reduction of cavitation damage and noise. This article reviews experimental and theoretical efforts to understand such phenomena. Two major areas of research are described, namely the dynamics of cavitation bubbles oscillating in a liquid of infinite extent, and the behavior of bubbles collapsing near rigid walls. POLYM. ENG.

Examining developmental differences in the social‐emotional problems among frequent bullies, victims, and bully/victims
Authors: O'Brennan Lindsey M. , Bradshaw Catherine P. , Sawyer Anne L. 
Published: December 2008

AbstractBullying poses a threat to children's social‐emotional functioning and their perceptions of school climate, yet few studies have examined different types of social‐emotional and behavior problems presented by children involved in bullying, as a bully, victim, or bully/victim across multiple school levels. The current study used data from 24,345 elementary‐, middle‐, and high‐school students to examine the association between frequent involvement in bullying and aggressive impulsivity, attitudes toward aggressive retaliation, internalizing symptoms, peer relations, and perceptions of school climate. Logistic regression analyses indicated that bully/victims were most likely to display internalizing symptoms, problems in peer relationships, and have poorer perceptions of the school environment. Both frequent bullies and bully/victims displayed aggressive‐impulsive behavior and endorsed retaliatory attitudes. High‐school students frequently involved in bullying tended to display the greatest risk for internalizing problems, but less risk for aggressive impulsivity. Developmental trends and implications for prevention and early intervention are discussed. © 2008 Wiley Periodicals, Inc.
MAP dendrimer elicits antibodies for detecting rat and mouse GH‐binding proteins

Published: December 2008

AbstractThe membrane‐bound rat GH‐R and an alternatively spliced isoform, the soluble rat GH‐BP, are comprised of identical N‐terminal GH‐binding domains; however, their C‐terminal sequences differ. Immunological reagents are needed to distinguish between the two isoforms in order to understand their respective roles in mediating the actions of GH. Accordingly, a tetravalent MAP dendrimer with four identical branches of a C‐terminal peptide sequence of the rat GH‐BP (GH‐BP263–279) was synthesized and used as an immunogen in rabbits. Solid‐phase peptide synthesis of four GH‐BP263–279 segments onto a tetravalent Lys2‐Lys‐β‐Ala‐OH core peptide was carried out using Fmoc chemistry. The mass of the RP‐HPLC‐purified synthetic product, 8398 Da, determined by ESI‐MS, was identical to expected mass. Three anti‐rat GH‐BP263–279 MAP antisera, BETO‐8039, BETO‐8040, and BETO‐8041, at dilutions of 10−3, recognized both the rat GH‐BP263–279 MAP and recombinant mouse GH‐BP with ED50s within a range of 5–10 fmol, but did not cross‐react with BSA in dot blot analyses. BETO‐8041 antisera (10−3 dilution) recognized GH‐BPs of rat serum and liver having Mrs ranging from 35 to 130 kDa, but did not recognize full‐length rat GH‐Rs. The antisera also detected recombinant mouse GH‐BPs. In summary, the tetravalent rat GH‐BP263–279 MAP dendrimer served as an effective immunogenic antigen in eliciting high titer antisera specific for the C‐termini of both rat and mouse GH‐BPs. The antisera will facilitate studies aimed at improving our understanding of the biology of GH‐BPs. Copyright © 2008 European Peptide Society and John Wiley & Sons, Ltd.

AbstractWe report the first example of conopeptide oxidation performed in a biocompatible ionic liquid, 1‐ethyl‐3‐methylimidazolium acetate ([C2mim][OAc]), which enables the efficient formation of both hydrophilic and poorly water‐soluble conotoxins compared with conventional methods. Moreover, the method features a high‐concentration approach ultimately leading to higher yields at reduced separation effort. Copyright © 2008 European Peptide Society and John Wiley & Sons, Ltd.
Between two worlds: local students in higher education and ‘scouse’/student identities
Authors: Holdsworth Clare 
Published: December 2008

AbstractThe restructuring of higher education (HE) finance and concomitant expansion of HE in England have implications for how students are recruited and their experiences of HE. While universities continue to be dominated by traditional entrants, widening participation policies have enabled more students from less‐advantaged backgrounds to study at university. One trend that is emerging as part of these activities is how the traditional expectation of leaving home to go to university is not necessarily being followed by ‘non‐traditional’ entrants, and many choose to study at their local university. This has implications for their experiences of student life as they have to negotiate the assumption that students are not ‘locals’ and vice versa. This paper explores how the assumption of mutual exclusivity of local and student identities is produced and perpetuated through limited interactions between ‘students’ and ‘locals’ and the implications these have for local students, who may find themselves isolated between the two communities.

Researching family migration decision‐making: a children‐in‐families approach
Authors: Bushin Naomi 
Published: December 2008

AbstractThis paper identifies that much geographical research exploring family migration decision‐making has overlooked the issue of children's agency. Motivations for family migration are considered to be influenced by children's presence within families, but it is often assumed that children have no actual involvement in making family migration decisions. In this paper I argue that changes in socio‐cultural constructions of ‘the family’ and ‘childhood’, alongside changes in familial forms and contexts, suggest that population geographers should consider the possibility that some children may be involved in making family migration decisions. I suggest that in order to develop deeper and more nuanced theorisations of family migration decision‐making, which reflect the involvement and experiences of children, a children‐in‐families approach to researching family migration may be fruitful. This approach is outlined in the paper, drawing on the findings of a mixed‐methods family migration research project with 37 families who moved within the UK. A possible framework for exploring children's levels of involvement in family migration decision‐making is introduced, and two key factors that influence their involvement are considered – children's age and parental consideration of children's ‘best interests’. By adopting a children‐in‐families approach to family migration decision‐making, I argue that current understandings of these processes will be furthered and population geographers will be able to contribute to broader debates on children's involvement in decision‐making within family contexts.

Gas‐phase fragmentation study of a novel series of synthetic 2‐oxo‐2H‐benzopyrano[2,3‐d]pyrimidine derivatives using electrospray ionization tandem mass spectroscopy measured with a quadrupole orthogonal time‐of‐flight hybrid instrument
Authors: Turki Hamida , Genestie Benoit , Gharbi Rachid El , Boussiry Sameh El , Banoub Joseph 
Published: December 2008

AbstractThe fragmentation patterns of a series of six novel synthesized benzopyranopyrimidine derivatives 1–6, possessing the same 2‐oxo‐2H‐benzopyrano[2,3‐d]pyrimidine backbone structure, were investigated by electrospray ionization mass spectrometry (ESI‐MS) and tandem mass spectrometry (MS/MS) techniques using a quadrupole orthogonal time‐of‐flight (QqToF)‐hybrid instrument. The series of six pure benzopyranopyrimidine compounds contained three constitutional isobaric isomers (compounds 4–6). A simple methodology, based on the use of ESI (positive ion mode) and increasing the declustering potential in the atmospheric pressure/vacuum interface resulting in collision‐induced dissociation (CID), was used to enhance the formation of the product ions. In general, the novel synthetic benzopyranopyrimidine derivatives 1–6 afforded exact accurate masses for the protonated molecules. This led to the confirmation of both molecular masses and chemical structures of the studied compounds. The breakdown routes of the protonated molecules were rationalized by conducting low‐energy CID‐MS/MS analyses. It was shown that the MS/MS fragmentation routes for the protonated molecules 1 and 2 were similar, and that the MS/MS fragmentations of the constitutional isobaric protonated molecules 5 and 6 were identical. It was also shown that the gas‐phase CID fragmentations of 5 and 6 were different from that of their constitutional isomer 4. Finally, the ESI‐MS and CID‐MS/MS analyses of the protonated molecules that were obtained from the monodeuterated benzopyranopyrimidine derivatives 1–6 confirmed the values obtained for the exact masses, the precise structural assignments of all product ions and all the pathways described in the proposed CID fragmentations.

Proof of the local REM conjecture for number partitioning. II. Growing energy scales
Authors: Borgs Christian , Chayes Jennifer , Mertens Stephan , Nair Chandra 
Published: December 2008

AbstractWe continue our analysis of the number partitioning problem with n weights chosen i.i.d. from some fixed probability distribution with density ρ. In Part I of this work, we established the so‐called local REM conjecture of Bauke, Franz and Mertens. Namely, we showed that, as n → ∞, the suitably rescaled energy spectrum above some fixed scale α tends to a Poisson process with density one, and the partitions corresponding to these energies become asymptotically uncorrelated. In this part, we analyze the number partitioning problem for energy scales αn that grow with n, and show that the local REM conjecture holds as long as n‐1/4αn → 0, and fails if αn grows like κn1/4 with κ > 0.We also consider the SK‐spin glass model, and show that it has an analogous threshold: the local REM conjecture holds for energies of order o(n), and fails if the energies grow like κn with κ > 0. © 2008 Wiley Periodicals, Inc.
