Cross Relationships between Cognitive Styles and Learner Variables in Online Learning Environment.

This study examines how students’ cognitive styles are correlated with their attitudes toward online education and learning behaviors in online learning environments. The Group Embedded Figures Test (GEFT) and the attitude survey toward online instruction were administered to 104 students enrolled in various online courses at the University of Tennessee. The study findings revealed that students’ cognitive styles were not significantly correlated with their attitudes and preference for instructional delivery modes while other factors such as previous online learning experience and computer competency were significantly correlated with students’ learning outcomes and attitudes toward online instruction. Recent advances in educational technology have improved educational environments by providing many enabling tools satisfying learners’ diverse needs. Advanced network systems especially brought about a revolutionary phase in education by allowing alternative “anytime and anywhere” learning delivery methods for online learners around the world. This kind of advancement in educational technology has produced many benefits for both individual learners and organizations in several ways. Individual learners take advantage of self-paced learning environments in which they have control over their pace of learning, information flow, selection of learning activities, and time management (Jung, 2001). Organizations increase return on investment (ROI) by saving time and cost for employee training through online learning solutions and performance supporting tools. As more and more individual learners and organizations choose online instruction as their alternative learning delivery option, e-learning markets become the world’s potentially largest information industry (Adam, Awerbuch, Slonim, Wegner, & Yesha 1997). In a recent survey of e-learning within business organizations in North America, about 43% of the organizations were in the process of utilizing e-learning for performance improvement in 2001, and 33% were planning to implement e-learning within the next three years (Sofres, 2001). A report by Screen Digest estimated the corporate market of e-learning in the U.S. at $3.5 billion in 2002 (Levis, 2002). As these

Angioscopic comparison of arterial repair after second-generation drug-eluting stent implantation into vulnerable and stable coronary plaques.

BACKGROUND
Arterial repair after intracoronary stenting depends on stent types and plaque vulnerability. The aim of this study was angioscopic comparison of arterial repair after implantation of the second-generation drug-eluting stents (G2-DES) between the stable and vulnerable plaques.


METHODS
Four types of G2-DES were successfully implanted into stable plaques (n=41) and vulnerable plaques (n=34): 13 and 9 Xience-everolimus-, 7 and 6 Endeavor-zotarolimus-, 15 and 9 Resolute-zotarolimus-, and 6 and 10 Nobori-biolimus-eluting stents (EES, E-ZES, R-ZES, and BES), respectively. Coronary angioscopy at 1-year follow-up revealed in-stent appearance, such as neointimal stent coverage (NSC), presence of yellow plaques (YP), and in-stent mural thrombus (MT). NSC was graded into poor and good coverage.


RESULTS
Yellow plaques and mural thrombi were found more frequently in the vulnerable plaques than in the stable plaques (29% vs. 12%, P=0.06; 12 vs. 0%, P=0.02; respectively). In EES, poor NSC was observed more frequently in the vulnerable plaques than in the stable plaques (54% vs. 11%, P=0.04). In BES, YP was observed more frequently in the vulnerable plaques than in the stable plaques (80% vs. 17%, P=0.01). In E-ZES and R-ZES, there were no significant differences with regards to angioscopic parameters between the stable and vulnerable plaques.


CONCLUSIONS
Arterial repair after EES and BES implantation into the vulnerable plaques remained vulnerable even at 1-year follow-up.
Control of DFIG-Based Wind Generation Systems under Unbalanced Network Supply

This paper develops a dynamic model and control scheme for DFIG systems to improve the performance and stability under unbalanced grid conditions. A dynamic DFIG model containing the positive and negative sequence components is presented using stator voltage orientation. The proposed model accurately illustrates the active power, reactive power and torque oscillations, and provides a basis for DFIG control system design during unbalanced network supply. Various control targets such as eliminating the oscillations of the torque, active/reactive power are discussed and the required rotor negative sequence current for fulfilling different control targets are described. Performance of a DFIG-based wind turbine under unbalanced condition using the proposed control method is evaluated by simulation studies using Matlab/Simulink. The proposed control scheme significantly attenuates the DFIG torque or active power oscillations during network unbalance whereas significant torque/power oscillations exist with the conventional control schemes.

Evaluating patient-reported outcome measurement comparability between paper and alternate versions, using the lung function questionnaire as an example.

OBJECTIVES
The goal of this study was to provide recommended steps to assess measurement comparability using a crossover study design and to demonstrate these steps using a short patient-reported outcome (PRO) instrument as an example.


METHODS
The example PRO instrument was administered via paper, Web, interactive voice response system, and interview; a randomized crossover design was used to gather data across the multiple administration types. Participants completed the PRO instrument, demographic and health questions, and a short preference questionnaire. Evaluation included comparisons of the item-level responses and agreement, comparison of mean scale scores, score classifications, and questions designed to collect usability and administration preference. Here the authors provide a four-step evaluation guide to evaluate measurement comparability and illustrate these steps using a case-finding tool.


RESULTS
In the example, item-level kappa statistics between the paper and the alternate versions ranged from good to excellent, intraclass correlation coefficient for mean scores were above 0.70, and the rate of disagreement ranged from 2% to 14%. In addition, although participants had an administration preference, they reported few difficulties with the versions they were assigned.


CONCLUSIONS
The steps described in this article provide a guide for evaluating whether to combine scores across administration versions to simplify analyses and interpretation under a crossover design. The guide recommends the investigation of item-level responses, summary scores, and participant usability/preference when comparing versions, with each step providing unique information to support comprehensive evaluation and informed decisions regarding whether to combine data.

Ionic transport through model membranes. I. Effects of accelerators of carcinogenesis.

Abstract 1. 1. Egg phosphatidyl choline adsorbed at an hydrocarbon-water interface was used as a physical model of a membrane-cytoplasm interface. The rate of transport of an anionic dyestuff could be measured across the interface from the aqueous to the organic phase under conditions of emulsification. The process simulates carrier transport in that the lecithin is an essential requirement, forming a tightly bound complex with the dye that becomes solubilized in the phospholipid micelles in the bulk organic phase. 2. 2. The standard organic phase was then modified by inclusion of n- alkanes from C 7 to C 24 . Most of the alkanes that have biological activity as accelerators of carcinogenesis, C 10 -C 20 , produced a significant reduction of the rate of transport of the dyestuff into the organic phase. 3. 3. Correlation was inferred between these observations and those of investigators of intracellular ionic transport in epithelial tissue cultures, who found a marked reduction of transport rates in certain malignant epithelia in contrast to the corresponding normal tissues. A membrane-mediated mechanism of control of initiated neoplastic cells is suggested. The hypothetical control depends upon a specific surface charge distribution at the lipoprotein-cytoplasm interface that is altered by the absorption of C 10 -C 20 n- alkanes .
Acceptability of a reformulated renal-specific micronutrient supplement

Sirs, There is no approved micronutrient supplement specifically formulated for children with chronic renal failure (CRF). Size, palatability, and format of any supplement may impact upon compliance with long-term treatment [1, 2]. We previously reported the use of a renal-specific micronutrient supplement (RSM) formulated by Vitaline Pharmaceuticals UK, which provided the recommended dietary reference intakes for vitamins B1, B2, B3, B5, B6, B12 as well as vitamins C, E, K, copper, zinc, and folic acid. The RSM was tested against our previous standard of Ketovite tablets and found to be preferable in terms of smell and taste but not size [3]. The results of the initial study encouraged us to reduce the size and shape of the RSM and produce it in a scored caplet form with half a caplet daily for children under 5 years of age and one caplet daily for children over 5 years. In addition, the folic acid was increased from 200 g to 1,000 g/caplet in an attempt to further reduce plasma homocysteine levels (Table 1) [4]. We recruited 25 children (16 male) from four regional paediatric nephrology units with a mean age of 11.6 years (range 1.8–17 years); 8 had CRF, 6 were on haemodialysis, and 11 on automated peritoneal dialysis. Patients had been on Ketovite tablets for a minimum of 3 months and the patient and/or parent completed a questionnaire before and after switching to the RSM for 2 weeks. Research ethics approval was obtained. There was a significant reduction (P<0.001) in the number of RSM caplets taken daily, with 92% of patients taking only one RSM caplet compared with 52% consuming three Ketovite tablets. The majority of patients swallowed the Ketovite or RSM whole, but the RSM did allow a number of children to chew the caplet (6 patients compared with 2 on Ketovite). There were 3 children that received the RSM either crushed or dissolved in water and administered via gastrostomy button or nasogastric tube. The results of the questionnaire showed that the smell and taste of the RSM was superior to that of Ketovite (P<0.001) with maintained ease of administration despite the larger caplet size of the RSM. Of the children, 60% favoured the RSM and a similar percentage wished to continue it after the study period. One child commented
THE COMPUTATIONAL COMPLEXITY OF AUTOMATED REDISTRICTING : IS AUTOMATION THE ANSWER ?

Ronald Reagan and Justice Brennan have both suggested that computers can remove the controversy and politics from redistricting. ' In fact proponents of automated redistricting claim that the "optimal" districting plan can be determined, given any set of specified values. The Supreme Court has expressed a similar sentiment by addressing such mechanical principles as contiguity and compactness in two recent redistricting cases, Shaw v. Reno4
Hypotensive transfusion reactions in the era of prestorage leukoreduction.

BACKGROUND
Clinical characteristics of hypotensive transfusion reactions (HyTRs) have not been evaluated in the context of universal prestorage leukoreduction.


STUDY DESIGN AND METHODS
A retrospective review of medical records of patients with HyTRs during the years 2011 and 2012 was performed at two academic medical institutions.


RESULTS
Thirty-five patients with 35 HyTRs were identified, with an incidence of 1.33 per 10,000 transfusions. Red blood cells (RBCs) were implicated in 21 (60.0%) reactions and platelets (PLTs) and plasma (PL) in 11 (31.4%) and three (8.6%), respectively. The HyTR rate per blood component was 0.019% for PLTs, 0.015% for RBCs, and 0.006% for PL. Mean patient age was 65 years (range, 2 months-87 years), five (14.3%) were pediatric (<18 years), and 20 (57.1%) were male. The most frequent clinical settings associated with HyTRs were cardiac surgery (n=13; 37.1%), hematology-oncology diseases (n=11; 31.4%), and general surgery (n=7; 20.0%). Extracorporeal circuits were used within 24 hours before the reaction in 16 patients (45.7%), including nine patients on cardiopulmonary bypass, four on dialysis or continuous venous-venous hemodialysis, and three on extracorporeal membrane oxygenation. Four patients (11.4%) received an angiotensin-converting enzyme inhibitor within 24 hours before the HyTR. Seventeen patients (48.6%) responded to stopping the transfusion and supportive treatment. Thirteen patients (37.1%) had severe reactions. No HyTR resulted in death.


CONCLUSION
In the absence of bedside leukoreduction filters, several medical situations are associated with HyTRs. The pathophysiology of HyTRs is yet to be defined. The US hemovigilance system allows for standardization of transfusion reactions, which facilitates their classification and study.
THE EFFECTS OF DEPOSITS MOBILIZATION ON FINANCIAL PERFORMANCE IN COMMERCIAL BANKS IN RWANDA . A CASE OF EQUITY BANK RWANDA LIMITED

This study is about to establish the effects of deposit mobilization on the bank financial performance in commercial banks in Rwanda. A case study of Equity bank Rwanda limited. Deposits are an indispensable tool commercial banks use to enhance its profitability through advancing deposits mobilized to its customers in form of loans which make in return interest to commercial banks. The lending activity is made possible only if the banks can mobilize enough funds from their customers. Specific objectives of this study are to determine the effect of marketing strategies on the financial performance of commercial banks in Rwanda, to establish the effect of interest rate changes on the financial performance of commercial banks in Rwanda and to determine the effect of banking technology introduced on the financial performance of commercial banks in Rwanda. The target population for the study was the bank managers involved in deposit mobilization namely the marketing team and the branch management team in Equity bank Rwanda. The research used a census to study a population of 27 staff. The main source of data was the primary and secondary data. The documentary method, the questionnaire as research instruments were used to get the data needed for the research. Data were processed by use of descriptive statistics after editing have been done. The computer software SPSS version 20 was used as a device to accommodate analysis. Pearson and Spearman’s correlation analysis was used to test the nature of relationship. The findings indicated that majority of the respondents (85%) confirmed that the brand name of the Equity Bank is recognized in the public this has made able overcoming challenges mostly facing high competition with other banks. The marketing strategy used made the bank to increase in terms of customers and it has led to the increase in deposits over the years. The findings also indicated that a positive change in deposits interest rate affects the level of deposits received and later on the profitability of the bank. The study revealed that the introduction of innovative banking technology has led to the increase in deposits at a low cost as opposed to the usual way of getting deposits through term deposits and made financial services accessible in the unbanked people. This also made the ROA, ROE, net profit increasing due as the loans volume increases. The statistical correlation revealed that there is a positive relationship between deposits mobilization and financial performance of commercial banks in Rwanda, the case of Equity Bank. The study recommends the bank to develop other strategies towards marketing and mobilize more deposits as they are indispensable tools towards the profitability of the bank.
Functional atlas of emotional faces processing: a voxel-based meta-analysis of 105 functional magnetic resonance imaging studies.

BACKGROUND
Most of our social interactions involve perception of emotional information from the faces of other people. Furthermore, such emotional processes are thought to be aberrant in a range of clinical disorders, including psychosis and depression. However, the exact neurofunctional maps underlying emotional facial processing are not well defined.


METHODS
Two independent researchers conducted separate comprehensive PubMed (1990 to May 2008) searches to find all functional magnetic resonance imaging (fMRI) studies using a variant of the emotional faces paradigm in healthy participants. The search terms were: "fMRI AND happy faces," "fMRI AND sad faces," "fMRI AND fearful faces," "fMRI AND angry faces," "fMRI AND disgusted faces" and "fMRI AND neutral faces." We extracted spatial coordinates and inserted them in an electronic database. We performed activation likelihood estimation analysis for voxel-based meta-analyses.


RESULTS
Of the originally identified studies, 105 met our inclusion criteria. The overall database consisted of 1785 brain coordinates that yielded an overall sample of 1600 healthy participants. Quantitative voxel-based meta-analysis of brain activation provided neurofunctional maps for 1) main effect of human faces; 2) main effect of emotional valence; and 3) modulatory effect of age, sex, explicit versus implicit processing and magnetic field strength. Processing of emotional faces was associated with increased activation in a number of visual, limbic, temporoparietal and prefrontal areas; the putamen; and the cerebellum. Happy, fearful and sad faces specifically activated the amygdala, whereas angry or disgusted faces had no effect on this brain region. Furthermore, amygdala sensitivity was greater for fearful than for happy or sad faces. Insular activation was selectively reported during processing of disgusted and angry faces. However, insular sensitivity was greater for disgusted than for angry faces. Conversely, neural response in the visual cortex and cerebellum was observable across all emotional conditions.


LIMITATIONS
Although the activation likelihood estimation approach is currently one of the most powerful and reliable meta-analytical methods in neuroimaging research, it is insensitive to effect sizes.


CONCLUSION
Our study has detailed neurofunctional maps to use as normative references in future fMRI studies of emotional facial processing in psychiatric populations. We found selective differences between neural networks underlying the basic emotions in limbic and insular brain regions.
On-demand treatment with alverine citrate/simeticone compared with standard treatments for irritable bowel syndrome: results of a randomised pragmatic study

BACKGROUND
In routine practice, irritable bowel syndrome (IBS) symptoms are often difficult to be relieved and impair significantly patients' quality of life (QoL). A randomised, double-blind, placebo-controlled study has shown the efficacy of alverine citrate/simeticone (ACS) combination for IBS symptom relief.


AIM
As IBS symptoms are often intermittent, this pragmatic study was designed to compare the efficacy of an on-demand ACS treatment vs. that of usual treatments.


METHODS
Rome III IBS patients were enrolled by 87 general practitioners who were randomly allocated to one of two therapeutic strategies: on-demand ACS or usual treatment chosen by the physician. The primary outcome measure was the improvement of the IBSQoL score between inclusion and month 6.


RESULTS
A total of 436 patients (mean age: 54.4 years; women: 73.4%) were included, 222 in the ACS arm and 214 patients in the usual treatment arm, which was mainly antispasmodics. At 6 months, improvement of IBSQoL was greater with ACS than with the usual treatment group (13.8 vs. 8.4; p < 0.0008). The IBS-severity symptom score (IBS-SSS) was lower with ACS than in the usual treatment arm with a mean (SE) decrease of 170.0 (6.6) vs. 110.7 (6.7), respectively (p = 0.0001). An IBS-SSS < 75 was more frequent in the ACS group (37.7% vs. 16.0%; p < 0.0001). Improvement of both abdominal pain and bloating severity was also greater with the on-demand ACS treatment, which was associated with both lower direct and indirect costs.


CONCLUSIONS
After 6 months, on-demand ACS treatment led to a greater improvement of QoL, reduced the burden of the disease and was more effective for IBS symptom relief than usual treatments.
