Selected AbstractsEffective Interaction With Patients With Schizophrenia: Qualitative Evaluation of the Interaction Skills Training ProgrammePERSPECTIVES IN PSYCHIATRIC CARE, Issue 4 2009Berno Van Meijel RN PURPOSE., The purpose of this study was to describe experiences of caregivers with the Interaction Skills Training Programme, and to evaluate the training effects observed by caregivers. DESIGN AND METHODS., A qualitative research design was applied. Semistructured interviews were conducted with 17 caregivers who had followed the training program. FINDINGS., The research findings clearly confirm the value of the program. Positive effects of the training were reported in terms of: (a) awareness and insightfulness; (b) the attitude of caregivers; (c) the quality of the therapeutic alliance; and (d) job perception. PRACTICE IMPLICATIONS., Training interactive skills may contribute to a better quality of care for chronic psychiatric patients. Based on the qualitative study, implementation of the skills training program can be recommended. [source] Incentive-based scheduling in Grid computingCONCURRENCY AND COMPUTATION: PRACTICE & EXPERIENCE, Issue 14 2006Yanmin Zhu Abstract With the rapid development of high-speed wide-area networks and powerful yet low-cost computational resources, Grid computing has emerged as an attractive computing paradigm. In typical Grid environments, there are two distinct parties, resource consumers and resource providers. Enabling an effective interaction between the two parties (i.e. scheduling jobs of consumers across the resources of providers) is particularly challenging due to the distributed ownership of Grid resources. In this paper, we propose an incentive-based peer-to-peer (P2P) scheduling for Grid computing, with the goal of building a practical and robust computational economy. The goal is realized by building a computational market supporting fair and healthy competition among consumers and providers. Each participant in the market competes actively and behaves independently for its own benefit. A market is said to be healthy if every player in the market gets sufficient incentive for joining the market. To build the healthy computational market, we propose the P2P scheduling infrastructure, which takes the advantages of P2P networks to efficiently support the scheduling. The proposed incentive-based algorithms are designed for consumers and providers, respectively, to ensure every participant gets sufficient incentive. Simulation results show that our approach is successful in building a healthy and scalable computational economy. Copyright © 2006 John Wiley & Sons, Ltd. [source] Excitation dynamics in a three-quantum dot system driven by optical near-field interaction: towards a nanometric photonic deviceJOURNAL OF MICROSCOPY, Issue 3 2003K. Kobayashi Summary Using density operator formalism, we discuss interdot excitation energy transfer dynamics driven by the optical near-field and phonon bath reservoir, as well as coherent excitation dynamics of a quantum dot system. As an effective interaction between quantum dots induced by the optical near-field, the projection operator method gives a renormalized dipole interaction, which is expressed as a sum of the Yukawa functions and is used as the optical near-field coupling of quantum dots. We examine one- and two-exciton dynamics of a three-quantum dot system suggesting a nanometric photonic switch, and numerically obtain a transfer time comparable with the recent experimental results for CuCl quantum dots. [source] RPA repair recognition of DNA containing pyrimidines bearing bulky adducts,JOURNAL OF MOLECULAR RECOGNITION, Issue 3 2008Irina O. Petruseva Abstract Recognition of new DNA nucleotide excision repair (NER) substrate analogs, 48-mer ddsDNA (damaged double-stranded DNA), by human replication protein A (hRPA) has been analyzed using fluorescence spectroscopy and photoaffinity modification. The aim of the present work was to find quantitative characteristics of RPA,ddsDNA interaction and RPA subunits role in this process. The designed DNA structures bear bulky substituted pyrimidine nitrogen bases at the inner positions of duplex forming DNA chains. The photoreactive 4-azido-2,5-difluoro-3- pyridin-6-yl (FAP) and fluorescent antracenyl, pyrenyl (Antr, Pyr) groups were introduced via different linker fragments into exo-4N of deoxycytidine or 5C of deoxyuridine. J-dU-containing DNA was used as a photoactive model of undamaged DNA strands. The reporter group was a fluorescein residue, introduced into the 5,-phosphate end of one duplex-forming DNA strand. RPA,dsDNA association constants and the molar RPA/dsDNA ratio have been calculated based on fluorescence anisotropy measurements under conditions of a 1:1 RPA/dsDNA molar ratio in complexes. The evident preference for RPA binding to ddsDNA over undamaged dsDNA distinctly depends on the adduct type and varies in the following way: undamaged dsDNA,<,Antr-dC-ddsDNA,<,mmdsDNA,<,FAPdU-, Pyr-dU-ddsDNA,<,FAP-dC-ddsDNA (KD,=,68,±,1; 25,±,6; 13,±,1; 8,±,2, and 3.5,±,0.5,nM correspondingly) but weakly depends on the chain integrity. Interestingly the bulkier lesions not in all cases have a greater effect on RPA affinity to ddsDNA. The experiments on photoaffinity modification demonstrated only p70 of compactly arranged RPA directly interacting with dsDNA. The formation of RPA,ddsDNA covalent adducts was drastically reduced when both strands of DNA duplex contained virtually opposite located FAP-dC and Antr-dC. Thus RPA requires undamaged DNA strand presence for the effective interaction with dsDNA bearing bulky damages and demonstrates the early NER factors characteristic features underlying strand discrimination capacity and poor activity of the NER system toward double damaged DNA.

[source] Quantum phase transition between antiferromagnetic and charge order in the Hubbard,Holstein modelPHYSICA STATUS SOLIDI (B) BASIC SOLID STATE PHYSICS, Issue 3 2010Johannes Bauer Abstract We explore the quantum phase transitions between two ordered states in the infinite dimensional Hubbard,Holstein model at half filling. Our study is based on the dynamical mean field theory (DMFT) combined with the numerical renormalization group (NRG), which allows us to handle both strong electron,electron and strong electron,phonon interactions. The transition line is characterized by an effective electron,electron interaction. Depending on this effective interaction and the phonon frequency ,0 one finds either a continuous transition or discontinuous transition. Here, the analysis focuses on the behavior of the system when the electron,electron repulsion U and the phonon-mediated attraction , are equal. We first discuss the adiabatic and antiadiabatic limiting cases. For finite ,0 we study the differences between the antiferromagnetic (AFM) and charge order, and find that when present the AFM state has a lower energy on the line. [source] Mixtures of correlated bosons and fermions: Dynamical mean-field theory for normal and condensed phasesANNALEN DER PHYSIK, Issue 9 2009K. Byczuk Abstract We derive a dynamical mean-field theory for mixtures of interacting bosons and fermions on a lattice (BF-DMFT). The BF-DMFT is a comprehensive, thermodynamically consistent framework for the theoretical investigation of Bose-Fermi mixtures and is applicable for arbitrary values of the coupling parameters and temperatures. It becomes exact in the limit of high spatial dimensions d or coordination number Z of the lattice. In particular, the BF-DMFT treats normal and condensed bosons on equal footing and thus includes the effects caused by their dynamic coupling. Using the BF-DMFT we investigate two different interaction models of correlated lattice bosons and fermions, one where all particles are spinless (model I) and one where fermions carry a spin one-half (model II). In model I the local, repulsive interaction between bosons and fermions can give rise to an attractive effective interaction between the bosons. In model II it can also lead to an attraction between the fermions. [source] How Should Governments Make Risky Policy Decisions?AUSTRALIAN JOURNAL OF PUBLIC ADMINISTRATION, Issue 3 2009J. Brian Hardaker Public policy-making does not follow the long-established and well-recognised principles of rational decision analysis under risk. Public views of risk are often inconsistent and seemingly irrational, and a gulf exists between risk perceptions and attitudes of the public and those of ,experts'. On the other hand, experts often claim unjustifiably high levels of confidence in their predictions of policy choice outcomes, creating a lack of public faith in their recommendations. While risky policy choices deserve more systematic decision analysis, many challenges remain to effective implementation of such analyses. Among the suggestions for improvement that we offer is the need for more effective interaction between policy-makers, decision analysts and the public. [source] Culturally diverse patient,nurse interactions on acute care wardsINTERNATIONAL JOURNAL OF NURSING PRACTICE, Issue 6 2006Jane Cioffi RN PhD The nurse,patient interaction is central to providing nursing care. This qualitative study explores nurses' and culturally diverse patients' experiences within nurse,patient relationships in acute care wards. Eight nurses and their respective patients volunteered to join the study and were interviewed. The three themes identified in relationships between nurses and culturally diverse patients were shared tension, perceived difference and held awareness. It is concluded from the study that relationships between nurses and culturally diverse patients in acute care wards during short episodes of hospitalization are not easy for nurses and need to receive deeper consideration as to how they can be developed more effectively. It is recommended that educational support be provided to develop more effective interactions between nurses and patients with research being carried out to investigate factors that can strengthen culturally diverse patient,nurse interactions in acute care settings. [source] Amino acid interaction preferences in proteinsPROTEIN SCIENCE, Issue 3 2010Anupam Nath Jha Abstract Understanding the key factors that influence the interaction preferences of amino acids in the folding of proteins have remained a challenge. Here we present a knowledge-based approach for determining the effective interactions between amino acids based on amino acid type, their secondary structure, and the contact based environment that they find themselves in the native state structure as measured by their number of neighbors. We find that the optimal information is approximately encoded in a 60 × 60 matrix describing the 20 types of amino acids in three distinct secondary structures (helix, beta strand, and loop). We carry out a clustering scheme to understand the similarity between these interactions and to elucidate a nonredundant set. We demonstrate that the inferred energy parameters can be used for assessing the fit of a given sequence into a putative native state structure. [source] Gender and Emotional Labor in Public Organizations: An Empirical Examination of the Link to PerformancePUBLIC ADMINISTRATION REVIEW, Issue 6 2006Kenneth J. Meier Scholars of public organizations have begun to emphasize emotional labor in studies of gender in the workplace, finding that the skills women bring to organizations are often overlooked and undercompensated even though they play a vital role in the organization. Emotional labor is an individual's effort to present emotions in a way that is desired by the organization. The authors hypothesize that employers with greater emotional labor expectations of their employees will have more effective interactions with clients, better internal relationships, and superior program performance. This article tests the effects of emotional labor in a bureaucratic workforce over time. Multiple regression results show that organizations with more women at the street level have higher overall organizational performance. Additionally, emotional labor contributes to organizational productivity over and above its role in employee turnover and client satisfaction. [source] |
