An experience sampling investigation of workplace interactions, affective states, and employee well‐being
Authors: Dimotakis Nikolaos , Scott Brent A. , Koopman Joel 
Published: December 2010

AbstractWe report an experience sampling study examining the within‐individual effects of workplace interpersonal interaction characteristics on affect at work and daily well‐being. A sample of 60 full‐time employees completed measures of interpersonal interaction characteristics and affective states during each of 10 workdays and a measure of job satisfaction at the end of each workday. Overall, the employees provided 380 day‐level data points. Hierarchical linear modeling (HLM) results indicated that interpersonal interaction characteristics were associated with affective states and job satisfaction. Furthermore, the effects of workplace interpersonal interactions on job satisfaction were mediated by affective states. Finally, positive affect mitigated the detrimental association between negative affect and job satisfaction. Copyright © 2010 John Wiley & Sons, Ltd.
Optimum chemotherapy regimens for neoadjuvant therapy of hepatic colorectal metastases
Authors: Davies Janine M. , Goldberg Richard M. 
Published: December 2010

AbstractResection of metastatic colorectal cancer hepatic lesions has gained support as surgical advances have made resections safer. Subsequently, the use of neoadjuvant therapy to cytoreduce tumors coupled with improved medical therapy has enhanced resection rates leading to improved outcomes. In “unresectable” disease, the addition of biologic therapies has further enhanced antitumor response, resulting in successful disease resection in certain patients. This review examines approaches to the neoadjuvant management of colorectal liver metastases with systemic therapies. J. Surg. Oncol. 2010;102:946–954. © 2010 Wiley‐Liss, Inc.
Poly(vinyl alcohol)‐Graft‐Poly(ethylene glycol)‐Supported Hydroxyproline Catalysis of Stereoselective Aldol Reactions
Authors: Kassem Tarek , Jia Xin , Zhu X.X. , Lubell William D. 
Published: December 2010

AbstractSummary: The good swelling and high loading of poly(vinyl alcohol)‐graft‐poly(ethylene glycol) (PVA‐g‐PEG) resins proved to be effective for performing supported proline‐catalyzed aldol reactions stereoselectively in a wide range of polar non‐protic, protic and non‐polar solvents as well as in neat substrate. The catalysts could be recovered by filtration and recycled, without significant loss of activity. The use of poly(vinyl alcohol)‐graft‐poly(ethylene glycol) matrix improved the solubility of the proline‐derived catalysts and expanded the scope of permissible solvents for performing selective aldol chemistry.
Polyisobutylene Phase‐Anchored Ruthenium Complexes

Published: December 2010

AbstractSummary: The use of polymers in general as ligands or sequestrants for metals has often focused on the use of cross‐linked polymers or readily available soluble polar polymers like poly(ethylene glycol). Our work shows that functional nonpolar polymers like polyisobutylene are viable alternatives and can be readily used as phase selectively soluble ligands or sequestrants for commonly used transition metal catalysts. This is illustrated in this work by the synthesis of ligands and sequestrants for ruthenium catalysts widely used in ring‐closing‐metathesis, cross‐metathesis, and ring‐opening metathesis polymerization. We show that a polyisobutylene terminally functionalized with a vinyl group can be converted by electrophilic aromatic substitution into species that phase immobilize a benzylidene Ru catalyst precursor, an N‐heterocyclic carbene ligand, or that can sequester a Ru complex by conversion of a reactive Ru alkylidene into a phase‐immobilized Fischer carbene complex. In all these cases, the Ru complexes that are formed are selectively soluble in a nonpolar or weakly polar phase of a liquid/liquid biphasic system – a system that can be efficiently formed either thermomorphically, by perturbation of an initially miscible solvent mixture, or by extraction.

Authors: Tongkate Pratoomrat , Lahti Paul M. , Sumranjit Jitapa 
Published: December 2010

AbstractSummary: Soluble para‐phenylenevinylenes (PPVs) with amino side groups and different spacers have been synthesized. Photophysical properties showed that these compounds emitted light in blue region when dissolved in methanol. They have been designed in order to be platforms for attaching different functional groups to the amino units. Molecule 5 was a model compound which showed a quantum efficiency of 52% in methanol. Different spacers were added to the model compound to yield molecules 6 and 7. The preliminary experiment showed that molecule 5 can interact with various metal ions in solution phase. The interaction was observed by the changes of fluorescent emission intensity of the molecule. This molecule will be further functionalized to be more specific in binding certain metal ions.

Authors: Kim Dongho , Kim Uisheon , Choi Jaehoon 
Published: December 2010

AbstractIn this article, a dual‐band multiple input multiple output (MIMO) antenna is proposed for Mobile WiMAX applications.The designed MIMO antenna consists of two planar inverted F antennas (PIFAs) and two isolators. The PIFAs have a volume of 12 × 10 × 4 mm3, which is small enough to be incorporated in a mobile MIMO terminal. The two isolators are designed symmetrically and placed between the two PIFAs to enhance the isolation performance of the MIMO antenna by suppressing the current flow between the antennas in the 2.3 and 3.4 GHz bands. The measured isolation values (S21) are lower than −15 and −22 dB at the 2.3 and 3.4 GHz bands, respectively. The key design parameters are extracted, and the parametric analysis performed. Also, the overall performance of the optimized MIMO antenna is presented. © 2010 Wiley Periodicals, Inc.

Published: December 2010

AbstractA K‐band power divider with metal bridge structures, which is based on the Wilkinson type is proposed using a standard 0.18 μm CMOS process. The metal bridge structures are applied to the power divider to achieve small size. Additionally, slow‐wave structures such as meandered line and slot pattern ground are used for small chip size and high performance. The proposed power divider shows an improved slow‐wave factor of 8.2% compared with a power divider with the conventional meandered line structure. The proposed power divider presents a size of 306 × 296 μm and wide bandwidth of 58% for isolation <15 dB. © 2010 Wiley Periodicals, Inc.

Published: December 2010

AbstractIn this article, a band‐switchable low noise amplifier using switching inductors is designed and measured. A voltage supply is fed through the structure of switching inductors. The switching inductors consist of three inductors in series and two PMOSFET switches, which are individually connected in parallel with one of the two inductors near the voltage supply. According to on or off states of two PMOSFET switches, there are four operation modes that generate a single‐band, two dual‐band, and a triple‐band transfer characteristics, respectively. The presented circuit is a modified cascoded amplifier configuration in which input stage is a common‐gate structure. The measured gains are nearly >11 dB at all operation frequency bands. The measured reflection coefficients are almost <−10 dB at all operation frequency bands. The noise figures are almost <4.5 dB at all operation frequency bands. The power consumption is 9 mW. The chip size is 1.02 × 1.2 mm2. © 2010 Wiley Periodicals, Inc. Microwave Opt Technol Lett 53:462–467, 2011; View this article online at wileyonlinelibrary.com. DOI 10.1002/mop.25707

A strain engineered voltage tunable millimeter‐wave ferrite phase shifter
Authors: Tatarenko A. S. , Srinivasan G. 
Published: December 2010

AbstractA 50‐GHz electric field tunable ferrite‐piezoelectric phase shifter based on a bilayer of single crystal M‐type hexagonal barium ferrite (BaM) and lead zirconate titanate (PZT) is discussed.A dc voltage applied to PZT results in a piezoelectric strain that manifests as an anisotropy field in BaM. A change in the voltage applied to PZT gives rise to variations in the anisotropy field and permeability of BaM and, therefore, a differential phase shift. A phase shift of 45° is measured when the voltage is increased from 0 to 400 V across a 0.5‐mm thick PZT. Theoretical estimates of the phase shift are in agreement with the data. © 2010 Wiley Periodicals, Inc.

Published: December 2010

AbstractA novel broadband transformer‐based CMOS power amplifier (PA) design method is studied in this article. To obtain a broadband PA, the parasitic parameters of the transformer are absorbed into the PAs load match and their impacts on bandwidth are studied. The fully‐integrated PA combined with an 8‐shaped transformer is implemented in 0.13 μm CMOS process with only 1.2 × 1.2 mm2 chip size and operates at Class AB mode. The single‐stage PA delivers 27.36 dBm output power with 27% efficiency and has 10.5 dB gain. It has 500 MHz bandwidth (1 dB degeneration) in the large and small signal measurements. IMD3 and IMD5 are also lower than −25 dBc at 19 dBm across the bandwidth. The spectrum of PA can meet the m‐WiMAX spectrum mask at 19 dBm average power level. © 2010 Wiley Periodicals, Inc.

Miniature DBR with series capacitive loading
Authors: Issa H. , Duchamp J‐M. , Ferrari P. , Abou‐Chahine S. 
Published: December 2010

AbstractA new miniature dual behavior resonator (DBR) topology with capacitors placed in series between the feed lines and the stubs is demonstrated. Design equations are derived. For a proof‐of‐concept, a first‐order prototype with a 1‐GHz working frequency and 70% size reduction is realized, measured, and compared with a classical DBR. The design method is simpler and more accurate compared with a miniaturized DBR with capacitors connected at the end of the stubs. Hence, the agreement between simulation and measurement results is better than previously published results of a miniature DBR using capacitors at the end of the stubs. Results also point out a quality factor improvement of 12%. © 2010 Wiley Periodicals, Inc. Microwave Opt Technol Lett 53:278–281, 2011; View this article online at wileyonlinelibrary.com.

Assessing the social impact of charitable organizations—four alternative approaches
Authors: Polonsky Michael , Grau Stacy Landreth 
Published: December 2010

Abstract

There is increased societal pressure on charities to improve performance. The questions that they must ask are: (1) Who is our audience? (2) What evaluation measures are important to the organization? and (3) What evaluation measures are best for the organization? There are a number of different approaches available for assessing performance, ranging from social accounting to more informal qualitative assessments of whether the organization's mission is being achieved. This paper draws on the industry and academic discussion of evaluations of nonprofit organizations to develop a four‐category typology of alternative approaches for audiences. It then identifies the benefits and limitations of each. The goal is to identify the steps that charities should use to determine which approach is most suited to their specific circumstances. It is proposed that a collaborative development of evaluation criteria, of whichever type, may be most appropriate as will draw together the experiences and resources of multiple parties, and may have broader appeal than evaluations proposed by individual nonprofits.Copyright © 2010 John Wiley & Sons, Ltd.

Published: December 2010

AbstractCancer is the second most common cause of death in children and young people (0–19 years) accounting for 16.2% of deaths in England and Wales in 2005. Only 37.6% children and young people who died from cancer in Yorkshire were referred to Martin House Children's Hospice (MH) during the period 1990–2005. A significantly higher proportion with central nervous system tumours and a significantly lower than expected proportion with leukaemia or lymphoma were referred for palliative care. There is potential to increase the proportion of children and young people with cancer who are referred to specialist palliative care services.

Published: December 2010

AbstractChronic kidney disease (CKD) is the end‐point of a number of renal and systemic diseases. The high incidence and financial burden of CKD makes it imperative to diagnose CKD at early stages when therapeutic interventions are far more effective. A key component of CKD is the development of renal fibrosis. Renal fibrosis is a complex process, associated with many cell types and pathways, resulting in structural and functional alterations. Identification of specific biomarkers of renal fibrosis may thus not only help us to understand the pathophysiological mechanisms involved in this process, but also improve diagnosis in the clinic. In this review, the existing literature on proteomic approaches to study renal fibrosis is presented and evaluated. The importance of using animal models along with patient material is discussed and future directions, considered key to this field, are proposed.

Crystal structure of the functional region of Uro‐adherence factor A from Staphylococcus saprophyticus reveals participation of the B domain in ligand binding

Published: December 2010

AbstractStaphylococci use cell wall‐anchored proteins as adhesins to attach to host tissues. Staphylococcus saprophyticus, a uropathogenic species, has a unique cell wall‐anchored protein, uro‐adherence factor A (UafA), which shows erythrocyte binding activity. To investigate the mechanism of adhesion by UafA, we determined the crystal structure of the functional region of UafA at 1.5 Å resolution. The structure was composed of three domains, designated as the N2, N3, and B domains, arranged in a triangular relative configuration. Hemagglutination inhibition assay with domain‐truncated mutants indicated that both N and B domains were necessary for erythrocyte binding. Based on these results, a novel manner of ligand binding in which the B domain acts as a functional domain was proposed as the adhesion mechanism of S. saprophyticus.
