Benchmarking the efficiency of the Korean banking sector: a DEA approach

– The purpose of this paper is to critically examine the sources of inefficiency in the Korean banking sector. The present study focuses on three different approaches: intermediation approach, value‐added approach, and operating approach, to differentiate how efficiency scores vary with changes in inputs and outputs. , – The paper utilizes the non‐parametric data envelopment analysis methodology to measure the efficiency of banks operating in the Korean banking sector. The method allows for the decomposition of technical efficiency (TE) into its mutually exhaustive components of pure technical and scale efficiencies. , – The empirical findings suggest that estimates of TE are consistently higher under an operating approach vis‐a‐vis the intermediation and value‐added approaches. On the other hand, banks are characterized by a relatively low level of TE under the intermediation approach. , – Further analysis on the performance of the Korean banking sector performance will examine the efficiency changes over time by employing the parametric stochastic frontier analysis method. Investigations into productivity changes over time, as a result of a technical change or technological progress or regression by employing the Malmquist productivity index could yet be another extension to the paper. , – The findings from this study are essential not only for the managers of the banks, but for numerous stakeholders such as the central banks, bankers associations, governments, and other financial authorities. Knowledge of these factors would also be helpful to the regulatory authorities and bank managers who formulate going forward policies for improved efficiency of the Korean banking sector. , – Unlike the previous studies on the efficiency of the Korean banking sector, the paper focuses on three different approaches: intermediation approach, value‐added approach, and operating approach to differentiate how efficiency scores vary with changes in inputs and outputs.
Antibody-mediated rejection across solid organ transplants: manifestations, mechanisms, and therapies

Solid organ transplantation is a curative therapy for hundreds of thousands of patients with end-stage organ failure. However, long-term outcomes have not improved, and nearly half of transplant recipients will lose their allografts by 10 years after transplant. One of the major challenges facing clinical transplantation is antibody-mediated rejection (AMR) caused by anti-donor HLA antibodies. AMR is highly associated with graft loss, but unfortunately there are few efficacious therapies to prevent and reverse AMR. This Review describes the clinical and histological manifestations of AMR, and discusses the immunopathological mechanisms contributing to antibody-mediated allograft injury as well as current and emerging therapies.
The Effects of Party and Preferences on Congressional Roll Call Voting

We assess the importance of parties in Congress by comparing roll-call voting behavior against the preferences of members of the House as expressed in surveys conducted during the 1996 and 1998 elections. The surveys were conducted by Project Vote Smart. Our findings support two key conclusions. First, both party and preferences mattered in predicting roll-call behavior in the 103d, 104th, and 105th Congresses. Second, the independent effects of party were present in only about 40% of roll calls. The incidence of party effects was highest on close votes, procedural votes, and key "party" issues. It was lowest on matters of conscience, such as abortion, and "off-the-first-dimension" issues, such as affirmative action and gun control.
A Comparison of the Transportability, and Its Role in Cytotoxicity, of Clofarabine, Cladribine, and Fludarabine by Recombinant Human Nucleoside Transporters Produced in Three Model Expression Systems

2-Chloro-9-(2′-deoxy-2′-fluoro-β-d-arabinofuranosyl)adenine (Cl-F-ara-A, clofarabine), a purine nucleoside analog with structural similarity to 2-chloro-2′-deoxyadenosine (Cl-dAdo, cladribine) and 9-β-d-arabinofuranosyl-2-fluoroadenine (F-ara-A, fludarabine), has activity in adult and pediatric leukemias. Mediated transport of the purine nucleoside analogs is believed to occur through the action of two structurally unrelated protein families, the equilibrative nucleoside transporters (ENTs) and the concentrative nucleoside transporters (CNTs). The current work assessed the transportability of Cl-F-ara-A, Cl-dAdo, and F-ara-A in cultured human leukemic CEM cells that were either nucleoside transport-defective or possessed individual human nucleoside transporter types and in Xenopus laevis oocytes and Saccharomyces cerevisiae yeast that produced individual recombinant human nucleoside transporter types. Cells producing hENT1 or hCNT3 exhibited the highest uptake of Cl-F-ara-A, whereas nucleoside transport-deficient cells and cells producing hCNT1 lacked uptake altogether. When Cl-F-ara-A transport rates by hENT1 were compared with those of Cl-dAdo and F-ara-A, Cl-dAdo had the highest efficiency of transport, although Cl-F-ara-A showed the greatest accumulation during 5-min exposures. In cytotoxicity studies with the CEM lines, Cl-F-ara-A was more cytotoxic to cells producing hENT1 than to the nucleoside transport-deficient cells. The efficiency of Cl-F-ara-A transport by oocytes with recombinant transporters was hCNT3 > hENT2 > hENT1 > hCNT2; no transport was observed with hCNT1. Affinity studies with recombinant transporters produced in yeast showed that hENT1, hENT2, and hCNT3 all had higher affinities for Cl-F-ara-A than for either Cl-dAdo or F-ara-A. These results suggest that the nature and activity of the plasma membrane proteins capable of inward transport of nucleosides are important determinants of Cl-F-ara-A activity in human cells.
Identification of the cellular target for eclosion hormone in the abdominal transverse nerves of the tobacco hornworm, Manduca sexta

The isolated abdominal central nervous system of Manduca sexta undergoes an increase in cyclic GMP (cGMP) when exposed to the insect peptide eclosion hormone (EH) before pupal ecdysis. Previously, cGMP immunocytochemistry revealed that the EH‐stimulated increase in cGMP was contained in numerous filamentous processes within the transverse nerve associated with each abdominal ganglion. These processes seemed to be the axons of neurosecretory cells projecting to this neurohemal organ. In the present paper, we now show that the EH‐stimulated cGMP is not present in neurosecretory terminals. There is no colocalization of the EH‐stimulated cGMP with immunoreactivity of two peptides, known to be present in axons in the transverse nerves. Furthermore, there is no colocalization of EH‐stimulated cGMP with the synaptic vesicle protein, synaptotagmin. The neurosecretory axons are localized to a narrow band at the anterior margin of the transverse nerve, whereas the cellular elements showing an EH‐stimulated cGMP increase are primarily present in the posterior region. There are two cell types in this region: a granular and a nongranular type. The cGMP immunoreactivity seems to be contained within the nongranular type. During adult development, the cells of the posterior compartment spread in a thin layer between the transverse and dorsal nerves, become positive for myosin immunoreactivity between pupal stages 5 and 8, and seem to form the adult ventral diaphragm muscles. We conclude that the EH‐sensitive filaments in the transverse nerves of Manduca are most likely to be intrinsic cells that subsequently develop into the ventral diaphragm muscles of the adult. J.

The Importance of Context in Managerial Work: The Case of Senior Hotel Managers in Greece

Qualitative research on the interplay between context and hospitality managerial work has not been previously addressed in the literature. Based on the works of Johns (2006) and Dierdorff et al. (2009), this research suggests that luxury senior hotel managers (GMs and department managers) are to a certain degree recipients of contextual/cultural influences, depending on the ownership status of the hotel. It is also argued that managerial work is shaped and exercised by a set of moderating factors, which are unique for each individual. Overall, the aim of this research is to increase the level of awareness and trigger further research in this topic area.
totSAT - Totally-Ordered Hierarchical Planning Through SAT

In this paper, we propose a novel SAT-based planning approach for hierarchical planning by introducing the SAT-based planner totSAT for the class of totally-ordered HTN planning problems. We use the same general approach as SAT planning for classical planning does: bound the problem, translate the problem into a formula, and if the formula is not satisfiable, increase the bound. In HTN planning, a suitable bound is the maximum depth of decomposition. We show how totally-ordered HTN planning problems can be translated into a SAT formula, given this bound. Furthermore, we have conducted an extensive empirical evaluation to compare our new planner against state-of-the-art HTN planners. It shows that our technique outperforms any of these systems.
Preoperative uracil, tegafur, and concomitant radiotherapy in operable rectal cancer: a phase II multicenter study with 3 years' follow-Up.

PURPOSE To assess tolerance and efficacy of preoperative treatment with uracil/tegafur and radiotherapy (RT) followed by surgery and postoperative flurouracil (FU)/leucovorin (LV) in patients with rectal cancer. PATIENTS AND METHODS Patients (n = 94) with potentially resectable tumors, ultrasound at stages T2N+ (n = 4), T3 (n = 77), T4 (n = 13) were treated with UFT (400 mg/m2/d, 5 days a week for 5 weeks) and concomitant RT to the pelvis (45 Gy; 1.8 Gy/d over 5 weeks). Patients underwent surgery 5 to 6 weeks later followed by four cycles of FU/LV. Primary end points included downstaging, pathologic responses, and sphincter-preserving surgery. Secondary end points were recurrence-free survival and overall survival. RESULTS All patients received the full RT dose. Fifteen patients (16%) needed UFT dose reduction. Preoperative G3+ toxicities included diarrhea (14%), leukopenia (1%), thrombocytopenia (1%), and nausea (4%). The downstaging rate was 54%, pathologic complete response (pCR) was 9% and, in an additional 23%, there were only residual microscopic foci. When cellular viability criteria were taken into account, the pCR was 15%. From 43 patients with abdominoperineal resection indication, 11 (25%) had sphincter-preserving surgery performed. Postoperative scheduled chemotherapy dose was not administered to 24% of patients because of G3+ toxicity (diarrhea, 8%; mucositis, 9%; and leukopenia, 7%). Patients with downstaging had significantly higher survival and recurrence-free survival rates than those without. At 3 years, actuarial patterns of failure were pelvic, 5% and distant, 11%. OS was 75%. CONCLUSION UFT combined with RT is safe and effective. In resectable rectal cancer, if preoperative treatment is considered, this approach can be an option.
The impact of corruption on financial markets

Purpose –The purpose of this paper is to focus specifically on the role of corruption in affecting financial markets. Recently, there are several studies that examine how one country’s level of corruption might affect asset prices in other countries. The aim of this article is to summarize how corruption may affect the bond and stock markets. Design/methodology/approach - The paper is organized as follows. Section 1 defines corruption and briefly examines the causes of corruption. Section 2 examines various measures of corruption and provides a ranking of countries. Section 3 explains how corruption may affect business and provide anecdotal evidence. Section 4 provides a summary of some empirical evidence of corruption on firm performances. Section 5 concludes. Findings - Across international financial markets, corruption is found to be associated with higher firm’s borrowing cost, lower stock valuation, and worse corporate governance. Originality/value - This paper provides a brief summary on research related to corruption and its impact on financial markets. Anecdotal evidence has shown the disruptive effect of corruption, and theoretical literature largely confirms this effect. Empirical studies show that the cost of corruption is highly significant in many different areas of the economy. In particular, across international financial markets, corruption is found to be associated with higher borrowing cost, lower stock valuation, and worse corporate governance.
Strategic planning tools and techniques in Jordan: awareness and use

This paper aims to explore the awareness and use of strategic planning tools and techniques by Jordanian public companies in the financial, service, and industrial sectors. A cross-sectional survey was employed rather than in-depth, case study-type analysis. Single respondents, rather than multiple respondents, participated in the study for each company. This is the first study of the use of strategic planning tools and techniques in Jordan and one of the first in the Middle East as a whole. The main findings of this research are: that the most used techniques by Jordanian companies are financial analysis (for own business), PEST or STEP analysis, Porter's five-forces analysis, and analysis of key (critical) success factors; that the managers of these companies have an awareness of most of the techniques surveyed; and that the use of strategy tools and techniques relates more to the size of company and less to the age and nature of business.

Partial and specific source memory for faces associated to other- and self-relevant negative contexts

Previous research has shown a source memory advantage for faces presented in negative contexts. As yet it remains unclear whether participants remember the specific type of context in which the faces were presented or whether they can only remember that the face was associated with negative valence. In the present study, participants saw faces together with descriptions of two different types of negative behaviour and neutral behaviour. In Experiment 1, we examined whether the participants were able to discriminate between two types of other-relevant negative context information (cheating and disgusting behaviour) in a source memory test. In Experiment 2, we assessed source memory for other-relevant negative (threatening) context information (other-aggressive behaviour) and self-relevant negative context information (self-aggressive behaviour). A multinomial source memory model was used to separately assess partial source memory for the negative valence of the behaviour and specific source memory for the particular type of negative context the face was associated with. In Experiment 1, source memory was specific for the particular type of negative context presented (i.e., cheating or disgusting behaviour). Experiment 2 showed that source memory for other-relevant negative information was more specific than source memory for self-relevant information. Thus, emotional source memory may vary in specificity depending on the degree to which the negative emotional context is perceived as threatening.
CNN-Based Joint Mapping of Short and Long Utterance i-Vectors for Speaker Verification Using Short Utterances

Text-independent speaker recognition using short utterances is a highly challenging task due to the large variation and content mismatch between short utterances. I-vector and probabilistic linear discriminant analysis (PLDA) based systems have become the standard in speaker verification applications, but they are less effective with short utterances. To address this issue, we propose a novel method, which trains a convolutional neural network (CNN) model to map the i-vectors extracted from short utterances to the corresponding long-utterance i-vectors. In order to simultaneously learn the representation of the original short-utterance i-vectors and fit the target long-version ivectors, we jointly train a supervised-regression model with an autoencoder using CNNs. The trained CNN model is then used to generate the mapped version of short-utterance i-vectors in the evaluation stage. We compare our proposed CNNbased joint mapping method with a GMM-based joint modeling method under matched and mismatched PLDA training conditions. Experimental results using the NIST SRE 2008 dataset show that the proposed technique achieves up to 30% relative improvement under duration mismatched PLDA-training conditions and outperforms the GMM-based method. The improved systems also perform better compared with the matched-length PLDA training condition using short utterances.
Regulation of energy substrate utilization and hepatic insulin sensitivity by phosphatidylcholine transfer protein/StarD2

Phosphatidylcholine transfer protein (PC‐TP, also known as StarD2) is a highly specific intracellular lipid binding protein with accentuated expression in oxidative tissues. Here we show that decreased plasma concentrations of glucose and free fatty acids in fasting PC‐TP‐deficient (Pctp−/−) mice are attributable to increased hepatic insulin sensitivity. In hyperinsulinemic‐euglycemic clamp studies, Pctp‐/‐ mice exhibited profound reductions in hepatic glucose production, gluconeogenesis, glycogenolysis, and glucose cycling. These changes were explained in part by the lack of PC‐TP expression in liver per se and in part by marked alterations in body fat composition. Reduced respiratory quotients in Pctp−/− mice were indicative of preferential fatty acid utilization for energy production in oxidative tissues. In the setting of decreased hepatic fatty acid synthesis, increased clearance rates of dietary triglycerides and increased hepatic triglyceride production rates reflected higher turnover in Pctp−/− mice. Collectively, these data support a key biological role for PC‐TP in the regulation of energy substrate utilization. —Scapa, E. F. , Pocai, A. , Wu, M.

Geographic patterns of genetic differentiation and plumage colour variation are different in the pied flycatcher (Ficedula hypoleuca)

The pied flycatcher is one of the most phenotypically variable bird species in Europe. The geographic variation in phenotypes has often been attributed to spatial variation in selection regimes that is associated with the presence or absence of the congeneric collared flycatcher. Spatial variation in phenotypes could however also be generated by spatially restricted gene flow and genetic drift. We examined the genetic population structure of pied flycatchers across the breeding range and applied the phenotypic QST (PST)–FST approach to detect indirect signals of divergent selection on dorsal plumage colouration in pied flycatcher males. Allelic frequencies at neutral markers were found to significantly differ among populations breeding in central and southern Europe whereas northerly breeding pied flycatchers were found to be one apparently panmictic group of individuals. Pairwise differences between phenotypic (PST) and neutral genetic distances (FST) were positively correlated after removing the most differentiated Spanish and Swiss populations from the analysis, suggesting that genetic drift may have contributed to the observed phenotypic differentiation in some parts of the pied flycatcher breeding range. Differentiation in dorsal plumage colouration however greatly exceeded that observed at neutral genetic markers, which indicates that the observed pattern of phenotypic differentiation is unlikely to be solely maintained by restricted gene flow and genetic drift.
Mission statements in Slovene enterprises

Purpose – The paper sets out to observe the absorption of strategic management practice in a leading Central and East European (CEE) economy, and to provide insight into institutional differences influencing the content of mission statements.Design/methodology/approach – The content of mission statements from large Slovene enterprises is compared with research on US mission statements.Findings – Mission statements in Slovene firms tend to emphasize customers, shareholders, and strategic suppliers significantly less often than do US firms. Corporate reputation, customer‐market scope and quality are also mentioned significantly less often in Slovene statements. Although some gaps between the theoretical ideal and corporate practice may exist in both settings, many differences may be explained by macroeconomic volatility, industry structure, and institutional environments.Research limitations/implications – Although the Slovene sample size is smaller than comparable US studies, it is an equivalent sample of .
Urinary schistosomiasis transmission in Epe, an urban community of Southwest Nigeria

Background: A survey of Schistosoma haematobium infection in Epe, an urban community in Lagos State, Southwest Nigeria, was carried out to ascertain the possibility that schistosomiasis, otherwise considered a rural disease, could reach urban populations. Materials and Methods: About 100 ml of voided urine samples from 200 pupils aged 6-13 years [109 (54.5%) males and 91 (45.5%) females], attending an Anglican primary school, Ebute Afuye, and a community primary school, Erepoto, were examined parasitologically for hematuria and S. haematobium ova following informed consent obtained from their parents/guardians. All samples were screened using polymerase chain reaction (PCR) amplification of the schistosome Dra1 gene. Fourteen Bulinus snails collected from the two sites, Ebute Afuye (6) and Erepoto (8), were screened for schistosome infection by the PCR amplification of the schistosome Dra1 gene. PCR-RFLP of the snails′ its region was analyzed for species identification and a subregion of the cox1 gene from four infected snails (two from each site) was amplified and sequenced. Results: In the Anglican primary school, Ebute Afuye, and community primary school, Erepoto, 16% and 29% were positive for hematuria, and 16% and 17% had schistosome ova, respectively. PCR analysis showed that 57% and 40% were positive for the infection in Anglican primary school, Ebute Afuye, and community primary school, Erepoto, respectively. PCR screening of the snails confirmed that four from Ebute Afuye and three from Erepoto were infected with schistosomes. PCR-RFLP showed that all the 14 snails were Bulinus truncatus while phylogenetic analysis of the sequenced partial cox1 gene corroborated the PCR-RFLP results. Conclusions: There was a high prevalence of S. haematobium infection among the participants detected by PCR, which was able to detect infection in cases otherwise shown to be negative by hematuria. We also observed that B. truncatus is one of the snail species responsible for the transmission of urinary schistosomiasis in the Epe community. For national control programs, it is very important that trends in the prevalence and intensity of schistosomiasis in urban cities be monitored.
