Executive Insights: Building Successful Export Business Relationships: A Behavioral Perspective

Abstract: Although the United States has been one of the leading actors in international trade, limited evidence exists as to individual U.S. company relationships with overseas customers. On the basis of a sample of 201 U.S. exporting manufacturers, the authors draw a comparison between harmonious and problematic foreign business relationships. The findings reveal that, as opposed to problematic cases, firms with harmonious relationships are more experienced, employ more people, and exhibit more active behavior toward conducting their foreign business. Such firms sell to a greater number of export markets, deal with more foreign customers, and obtain more orders. The study also shows that harmonious relationships with overseas customers are distinguished by greater dependence, trust, understanding, commitment, communication, and cooperation but less distance, uncertainty, and conflict between the parties. The article provides export management with a set of guidelines for establishing, developing, and sus...

Physical constraints on charge transport through bacterial nanowires

Abstract: Extracellular appendages of the dissimilatory metal-reducing bacterium Shewanella oneidensis MR-1 were recently shown to sustain currents of 1010 electrons per second over distances of 0.5 microns [El-Naggar et al., Proc. Natl. Acad. Sci. U. S. A., 2010, 107, 18127]. However, the identity of the charge localizing sites and their organization along the “nanowire” remain unknown. We use theory to predict redox cofactor separation distances that would permit charge flow at rates of 1010 electrons per second over 0.5 microns for voltage biases of ≤1V, using a steady-state analysis governed by a non-adiabatic electron transport mechanism. We find the observed currents necessitate a multi-step hopping transport mechanism, with charge localizing sites separated by less than 1 nm and reorganization energies that rival the lowest known in biology.

HIV-1 subtype distribution and its demographic determinants in newly diagnosed patients in Europe suggest highly compartmentalized epidemics

Abstract: Understanding HIV-1 subtype distribution and epidemiology can assist preventive measures and clinical decisions. Sequence variation may affect antiviral drug resistance development, disease progression, evolutionary rates and transmission routes. We investigated the subtype distribution of HIV-1 in Europe and Israel in a representative sample of patients diagnosed between 2002 and 2005 and related it to the demographic data available. 2793 PRO-RT sequences were subtyped either with the REGA Subtyping tool or by a manual procedure that included phylogenetic tree and recombination analysis. The most prevalent subtypes/CRFs in our dataset were subtype B (66.1%), followed by sub-subtype A1 (6.9%), subtype C (6.8%) and CRF02_AG (4.7%). Substantial differences in the proportion of new diagnoses with distinct subtypes were found between European countries: the lowest proportion of subtype B was found in Israel (27.9%) and Portugal (39.2%), while the highest was observed in Poland (96.2%) and Slovenia (93.6%). Other subtypes were significantly more diagnosed in immigrant populations. Subtype B was significantly more diagnosed in men than in women and in MSM > IDUs > heterosexuals. Furthermore, the subtype distribution according to continent of origin of the patients suggests they acquired their infection there or in Europe from compatriots. The association of subtype with demographic parameters suggests highly compartmentalized epidemics, determined by social and behavioural characteristics of the patients.

An internal customer service quality data envelopment analysis model for bank branches

Abstract: Over the last few years data envelopment analysis (DEA) has been gaining increasing popularity as a performance assessment methodology. DEA has been successfully applied to bank branch performance evaluation. However, most DEA models which have been developed for bank branch performance assessment do not include service quality as an output. Service quality has been considered by many as the key to gaining competitive advantage and customer loyalty. Develops a DEA model that can be used to provide direction for improvement to branches which do not use their resources in the most efficient way to produce service quality. Focuses on internal customer service quality which is sometimes easier to measure. Presents results from an empirical study undertaken at a bank to demonstrate the applicability of the model.

Dynamic IEEE Test Systems for Transient Analysis

Abstract: Transient stability analysis is performed to assess the power system's condition after a severe contingency and is carried out using simulations. To adequately assess the system's transient stability, the correct dynamic models for the machines (i.e., generators, condensers, and motors) along with their dynamic parameters must be defined. The IEEE test systems contain the data required for steady-state studies. However, neither the dynamic model of the machines nor their specific parameters have been established for transient studies. As a result, there is a demand for test bed systems suitable for transient analysis. This paper defines dynamic machine models along with their parameters for each IEEE test bed system, thus producing full dynamic models for all test systems. It is important to mention that the parameters of the proposed dynamic models are based on typical data. The test systems are subjected to large disturbances, and a case study for each test system, which examines the frequency, angle, and voltage stability, is presented. Furthermore, the proposed dynamic IEEE test systems, implemented in PowerWorld, are available online.
