Bonding in Mercury Molecules Described by the Normalized Elimination of the Small Component and Coupled Cluster Theory
Authors: Cremer Dieter , Kraka Elfi , Filatov Michael 
Published: November 2008

AbstractBond dissociation energies (BDEs) of neutral HgX and cationic HgX+ molecules range from less than a kcal mol−1 to as much as 60 kcal mol−1. Using NESC/CCSD(T) [normalized elimination of the small component and coupled‐cluster theory with all single and double excitations and a perturbative treatment of the triple excitations] in combination with triple‐zeta basis sets, bonding in 28 mercury molecules HgX (X=H, Li, Na, K, Rb, CH3, SiH3, GeH3, SnH3, NH2, PH2, AsH2, SbH2, OH, SH, SeH, TeH, O, S, Se, Te, F, Cl, Br, I, CN, CF3, OCF3) and their corresponding 28 cations is investigated. Mercury undergoes weak covalent bonding with its partner X in most cases (exceptions: X=alkali atoms, which lead to van der Waals bonding) although the BDEs are mostly smaller than 12 kcal mol−1. Bonding is weakened by 1) a singly occupied destabilized σ*‐HOMO and 2) lone pair repulsion. The magnitude of σ*‐destabilization can be determined from the energy difference BDE(HgX)−BDE(HgX+), which is largest for bonding partners from groups IVb and Vb of the periodic table (up to 80 kcal mol−1). BDEs can be enlarged by charge transfer from Hg and increased HgX ionic bonding, provided the bonding partner of Hg is sufficiently electronegative. The fine‐tuning of covalent and ionic bonding, σ‐destabilization, and lone‐pair repulsion occurs via relativistic effects where 6s AO contraction and 5d AO expansion are decisive. Lone pair repulsion involving the mercury 5d AOs plays an important role in the case of some mercury chalcogenides HgE (E=O, Te) where it leads to 3Π rather than 1Σ+ ground states. However, both HgE(3Π) and HgE(1Σ+) should not be experimentally detectable under normal conditions, which is in contrast to experimental predictions suggesting BDE values for HgE between 30 and 53 kcal mol−1. The results of this work are discussed with regard to their relevance for mercury bonding in general, the chemistry of mercury, and reactions of elemental Hg in the atmosphere.
Sorting and expansion of murine embryonic stem cell colonies using micropallet arrays
Authors: Shadpour Hamed , Sims Christopher E. , Thresher Randy J. , Allbritton Nancy L. 
Published: November 2008

AbstractIsolation of cell colonies is an essential task in most stem cell studies. Conventional techniques for colony selection and isolation require significant time, labor, and consumption of expensive reagents. New microengineered technologies hold the promise for improving colony manipulation by reducing the required manpower and reagent consumption. Murine embryonic stem cells were cultured on arrays composed of releasable elements termed micropallets created from a biocompatible photoresist. Micropallets containing undifferentiated colonies were released using a laser‐based technique followed by cell collection and expansion in culture. The micropallet arrays provided a biocompatible substrate for maintaining undifferentiated murine stem cells in culture. A surface coating of 0.025% gelatin was shown to be optimal for cell culture and collection. Arrays composed of surface‐roughened micropallets provided further improvements in culture and isolation. Colonies of viable stem cells were efficiently isolated and collected. Colonies sorted in this manner were shown to remain undifferentiated even after collection and further expansion in culture. Qualitative and quantitative analyses of sorting, collection efficiency, and cell viability after release and expansion of stem cell colonies demonstrated that the micropallet array technology is a promising alternative to conventional sorting methods for stem cell applications. © 2008 International Society for Advancement of Cytometry
SFMAC: A novel method for analyzing multiple parameters on lymphocytes with a single fluorophore in cell‐microarray system
Authors: Tajiri Kazuto , Kishi Hiroyuki , Ozawa Tatsuhiko , Sugiyama Toshiro , Muraguchi Atsushi 
Published: November 2008

AbstractThe analysis of single cells with multiple parameters in flow cytometry or microscopy requires suitable combinations of fluorophores and optical filters. The growing demands for the multiplex analysis of cells increase the requirements for developing new fluorophores and techniques. We have developed a novel method of analyzing a large number of cells with multiple parameters on a single‐cell basis using a single fluorophore. Cells were arrayed onto a microwell array chip with an array of 45,000 microwells, which could capture single cells, stained with a phycoerythrin (PE)‐conjugated antibody to a marker, and analyzed with a cell‐scanner. After analysis, we photobleached the PE molecules by irradiating the sample with blue light. Because the fluorescence of PE was not recovered after the photobleaching and the analyzed cells remained in the same microwells on the chip, we could repeatedly stain and analyze the same cells with other markers using PE. We applied a method of analyzing lymphocytes from 100 μL of peripheral blood for cytokine secretion and expression of intracellular proteins as well as for multiple cell surface markers. This novel method enables us to analyze multiple markers with a single fluorophore using a simple apparatus. The method may expand the scope of cytometry. © 2008 International Society for Advancement of Cytometry
Corruption‐aware adaptive increase and adaptive decrease algorithm for TCP error and congestion controls in wireless networks
Authors: Cui Lin , Koh Seok J. 
Published: November 2008

AbstractThe conventional TCP tends to suffer from performance degradation due to packet corruptions in the wireless lossy channels, since any corruption event is regarded as an indication of network congestion. This paper proposes a TCP error and congestion control scheme using corruption‐aware adaptive increase and adaptive decrease algorithm to improve TCP performance over wireless networks. In the proposed scheme, the available network bandwidth is estimated based on the amount of the received integral data as well as the received corrupted data. The slow start threshold is updated only when a lost but not corrupted segment is detected by sender, since the corrupted packets still arrive at the TCP receiver. In the proposed scheme, the duplicated ACKs are processed differently by sender depending on whether there are any lost but not corrupted segments at present. Simulation results show that the proposed scheme could significantly improve TCP throughput over the heterogeneous wired and wireless networks with a high bit error rate, compared with the existing TCP and its variants.

Oxidovanadium Complexes for the Consumption of Alkylating Toxins
Authors: Fautch Jessica M. , Fanwick Phillip E. , Wilker Jonathan J. 
Published: November 2008

AbstractCarcinogens found in cooked foods, tobacco smoke, and vehicle exhaust undergo metabolic activation to pernicious alkylating toxins, yield damaged DNA, and promote cancerous growth. Vanadium has been shown to decrease the occurrence of cancers, possibly by intercepting such toxins before DNA damage can occur. According to recent results, nucleophilic oxido salts of vanadium can prevent this DNA alkylation. Although effective at detoxification and preventing DNA damage, vanadate salts equilibrate in solution to multiple coexisting species and can exhibit toxicity. Ligand‐enforced coordination geometries may minimize such equilibrations, thereby decreasing toxicity and providing a means to control reactivity. As part of our efforts to detoxify alkylating agents, here we are studying reactions between oxidovanadium complexes and toxins. Alkylating agents such as diethyl sulfate were treated with a series of new oxidovanadium complexes of the salicylidenehydrazide ligand, [VO2(salhyph(R)2)]–. These complexes consumed a collection of alkylating agents and brought about transformation to alcohols. Changing the ligand substituents (R = –OCH3,–CH3, –H, –NO2) yielded a series of compounds with varied degrees of electron density. Kinetic experiments indicated that there may be a correlation between electron density and reactivity with alkylating toxins. The design and reactivity of these compounds indicate that we may be able to exert control over interactions between carcinogens and metal complexes. Such principles may be helpful in developing new compounds for the prevention of cancer. (© Wiley‐VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2009)
Do Metal–Metal Multiply‐Bonded “Ligands” Have a trans Influence? Structural and Magnetic Comparisons of Heterometallic CrCr···Co and MoMo···Co Interactions
Authors: Nippe Michael , Victor Eric , Berry John F. 
Published: November 2008

AbstractReported here are two new compounds containing either a CrCr···Co [1, CrCrCo(dpa)4Cl2, dpa = 2,2′‐dipyridylamide] or a MoMo···Co [2, MoMoCo(dpa)4Cl2] framework both having a multiply‐bonded unit (CrCr in 1, MoMo in 2) in close proximity to the Co2+ ion and trans to a Co–Cl bond. Variable temperature magnetic susceptibility measurements reveal 1 to have a temperature‐dependent spin equilibrium between a low‐spin (S = 1/2) and high‐spin (S = 3/2) state, whereas the Co2+ ion in 2 exists solely in its high‐spin state. The crystal structures of 1 and 2 were determined. Variable temperature crystallographic data of 1 at 100 K and at room temperature reveal that the spin‐transition affects not only the Co–ligand bond lengths but also the terminal Cr–ligand bond lengths. Whereas the Cr···Co distance becomes shorter by 0.13 Å in the low‐spin form, the Co–Cldistance becomes longer by 0.2 Å. These observations,along with the crystal structure of 2, suggest that the multiply‐bonded MM group has a trans influence on the Co2+ ion.(© Wiley‐VCH Verlag GmbH & Co.

BiBr3‐Promoted Activation of Peracetylated Glycosyl Iodides: Straightforward Access to Synthetically Useful 2‐O‐Deprotected Allyl Glycosides
Authors: Pastore Antonello , Adinolfi Matteo , Iadonisi Alfonso 
Published: November 2008

AbstractSubstoichiometric amounts of BiBr3 are able to promote anomeric activation of acetylated glycosyl iodides. This reactivity can be exploited for straightforward access to allyl glycosides unprotected at the O‐2 position. The reported protocol appears to be convenient in comparison with the pre‐existing ones in that shorter experimental times are needed and the use of strong acids is avoided. Suitable structural features of substrates (6‐deoxy sugars or use of benzoyl or methoxycarbonyl 2‐O‐participating groups) switch the process to a preferential glycosidation without deprotection at the O‐2 position.(© Wiley‐VCH Verlag GmbH & Co.

Application of imaging capillary IEF for characterization and quantitative analysis of recombinant protein charge heterogeneity
Authors: Sosic Zoran , Houde Damian , Blum Andy , Carlage Tyler , Lyubarskaya Yelena 
Published: November 2008

AbstractIn this work several aspects of imaging capillary IEF (icIEF) application for charge heterogeneity analysis of recombinant proteins and monoclonal antibodies have been discussed. Advantages of the method as compared with traditional approaches for determination of biomolecule charge heterogeneity, such as gel and IEC, have been demonstrated. Correlation of icIEF‐detected protein isoforms with the charge heterogeneity determined by IEC has been shown for a representative recombinant monoclonal antibody. Identification of charged variants collected from IEC has been performed by ESI‐MS. Qualification of an icIEF method for use in quality control environment for quantitative analysis of recombinant protein charge heterogeneity and monitoring protein stability has also been discussed. The intermediate precision for determination of pI of main or main acidic species was ≤0.2% RSD. Relative % peak areas for acidic, main and basic species were reproducible within 1.9, 0.9 and 16.6% RSD, respectively. Based on the assay performance evaluation, icIEF assay has been shown to allow for fast method development, short analysis time and high sample throughput. Some aspects of the method specificity for use as an identity test in biopharmaceutical development have been discussed.
Explanation for the electrophoresis behaviour of DNA condensation induced by pseudopolyrotaxane of different lengths
Authors: Hou Sen , Yang Kun , Feng Xi‐Zeng 
Published: November 2008

AbstractDNA condensation has received much attention as a prerequisite for the transport of gene delivery vectors in living cells. Electrophoresis assay is a common method to investigate the interaction between DNA and gene delivery vectors during the DNA condensation process. In order to probe the relation between DNA condensation status and the corresponding electrophoresis behaviour, we synthesized a series of pseudopolyrotaxanes (PPRs) by threading 6‐[(6‐aminohexyl)amino]‐6‐deoxy‐β‐CD dichloride on the polypropylene glycol and investigated their DNA condensation efficiency by electrophoresis assay. The PPRs of the middle length exhibited the best DNA condensation efficiency in electrophoresis assay, while the shorter or the longer homologues exhibited only slight DNA condensation efficiency. To explain this phenomenon, we investigated the hydrodynamic diameter, the particle size, the zeta potential and the binding affinity of these PPRs/DNA complexes. We found that the stability of PPRs/DNA complexes played an important role in determining the electrophoresis behaviour. Based on the data, we also pointed out the deficiency of electrophoresis assay in investigating the DNA condensation process. Our findings are helpful for researchers engaged in DNA condensation study.
Organizational change cynicism: The role of employee involvement
Authors: Brown Michelle , Cregan Christina 
Published: November 2008

AbstractOrganizational change efforts can bring about a range of outcomes: some intended, such as organizational survival and profitability, and some unintended, such as heightened levels of organizational change cynicism (OCC) among employees. This article focuses on processes for managing OCC: we examine the role of information sharing and involvement in decision making as ways to lessen employee reports of OCC. While both of these strategies have the potential to be effective, they rest on a significant assumption—namely, that employees will enthusiastically embrace any opportunities to become involved. In this research, we investigate this assumption through an analysis of the relationship between an employee's willingness to become involved (”active orientation”) on employee reports of their OCC. We find, using data from 1,214 public‐sector employees, that an active orientation toward involvement plays a significant role as a moderator in reducing employee reports of OCC. The findings suggest that HR practitioners concerned about OCC should encourage their line managers to adopt a participatory style of management (information sharing, involvement in decision making), especially in those workplaces where employees are more likely to embrace the opportunities for involvement. © 2008 Wiley Periodicals, Inc.
Strategic HRM in China: Configurations and competitive advantage
Authors: Chow Irene H. , Huang Jia‐Chi , Liu Shanshi 
Published: November 2008

AbstractThe strategic HR literature suggests that a firm will perform better through internal appropriate fit among HRM practices (the configuration fit) and through external appropriate fit between a firm's HRM practices and business strategy. The present study adopts a configuration approach to identify unique patterns of HR practices and business strategy that are posited to be maximally effective. The proposed relationships were empirically tested by surveying with a sample of 241 business firms in Guangzhou, South China, to find out the extent that four HR configurations could be successfully adopted in the Chinese context. The results revealed that HR configurations are significantly related to effect in predicting overall outcome performance and turnover, but not significantly related to effect on sales growth and profit growth rates. Research findings showed not only competitive strategies are significantly related to effect on HR configurations. The results also showed significant interaction effects between HR configurations and business strategy in their effect on profit and sales growth. These results further extended support for a contingency perspective in strategic HRM to the Chinese context, with significant practical implications for managing HRM in China. © 2008 Wiley Periodicals, Inc.
Human resource manager insights on creating and sustaining successful reduced‐load work arrangements
Authors: Friede Alyssa , Kossek Ellen Ernst , Lee Mary Dean , Macdermid Shelley 
Published: November 2008

AbstractAlthough human resource managers have critical insights into the successful implementation of reduced‐load work arrangements, relatively few studies focus on their perspective. These arrangements are a growing work form for employees who choose to work less than full‐time with a commensurate decrease in salary. Qualitative data analysis was used to identify key success factors noted in interviews with 52 HR managers in 39 companies. Individual employee characteristics (e.g., self‐regulatory work habits) were viewed as most critical. Also important were the design of the arrangement (e.g., clarifying the arrangement in advance) and workgroup relationships (e.g., positive supervisor‐employee relationships). We conclude with eight new takeaways for HR managers on how to create and sustain successful reduced‐load work arrangements and directions for future research and practice. © 2008 Wiley Periodicals, Inc.
Is the doctor in? A relational approach to job design and the coordination of work
Authors: Gittell Jody Hoffer , Weinberg Dana Beth , Bennett Adrienne L. , Miller Joseph A. 
Published: November 2008

AbstractWhen designing jobs, the degree of specialization is a key consideration. Though functional specialization allows workers to develop deep areas of expertise, it also increases the challenge of coordinating their work. In this article, we propose the concepts of stage‐ and site‐based specialization and posit that together they can counteract the divisive effects of functional specialization. Taking advantage of a natural experiment in physician job design at a Massachusetts hospital, we explore the impact of stage‐ and site‐based specialization on coordination and performance outcomes. Building on recent interest in relational approaches to job design, this study is the first to link relational job design to relational outcomes such as coordination. Our findings have practical implications for job design in professional service settings such as education, consulting, and health care. © 2008 Wiley Periodicals, Inc.
Employee reactions to gainsharing under seniority pay systems: The mediating effect of distributive, procedural, and interactional justice
Authors: Kwon Seungwoo , Kim Min Soo , Kang Sung‐Choon , Kim Myung Un 
Published: November 2008

AbstractThis study examines the effects of gainsharing under seniority‐based pay systems on employee attitudes in Korea. It is hypothesized that gainsharing, which emphasizes performance, employee participation, and cooperation enhances employee perceptions of distributive, procedural, and interactional justice, and that this, in turn, produces positive employee attitudes. The participants were a sample of individuals from five firms that combined seniority‐based pay and gainsharing incentives and five comparable firms that used only seniority‐based pay. The results supported the partial mediation model whereby distributive and interactional justice partially mediated the effects of gainsharing on employee attitudes, but procedural justice did not. The practical implications of this international compensation research include careful consideration of the integration of gainsharing with the total rewards mix in an organization. © 2008 Wiley Periodicals, Inc.
