Determinants of ERP implementation knowledge transfer

Our study examined the determinants of ERP knowledge transfer from implementation consultants (ICs) to key users (KUs), and vice versa. An integrated model was developed, positing that knowledge transfer was influenced by the knowledge-, source-, recipient-, and transfer context-related aspects. Data to test this model were collected from 85 ERP-implementation projects of firms that were mainly located in Zhejiang province, China. The results of the analysis demonstrated that all four aspects had a significant influence on ERP knowledge transfer. Furthermore, the results revealed the mediator role of the transfer activities and arduous relationship between ICs and KUs. The influence on knowledge transfer from the source’s willingness to transfer and the recipient’s willingness to accept knowledge was fully mediated by transfer activities, whereas the influence on knowledge transfer from the recipient’s ability to absorb knowledge was only partially mediated by transfer activities. The influence on knowledge transfer from the communication capability (including encoding and decoding competence) was fully mediated by arduous relationship. 2008 Elsevier B.V. All rights reserved.
Randomized comparison of a polymer-free sirolimus-eluting stent versus a polymer-based paclitaxel-eluting stent in patients with diabetes mellitus: the LIPSIA Yukon trial.

OBJECTIVES
The objective of the study was to assess noninferiority of the polymer-free sirolimus-eluting Yukon Choice stent (Translumina GmbH, Hechingen, Germany) compared with the polymer-based Taxus Liberté stent (Boston Scientific, Natick, Massachusetts) with regard to the primary endpoint, in-stent late lumen loss, at 9 months in patients with diabetes mellitus.


BACKGROUND
The Yukon Choice stent has been evaluated in several randomized controlled trials before, albeit to date, there has been no trial that exclusively enrolled patients with diabetes mellitus.


METHODS
Patients with diabetes mellitus undergoing percutaneous coronary intervention for clinically significant de novo coronary artery stenosis were randomized 1:1 to receive either the polymer-free sirolimus-eluting Yukon Choice stent or the polymer-based paclitaxel-eluting Taxus Liberté stent.


RESULTS
A total of 240 patients were randomized. Quantitative coronary angiography was available for 79% of patients. Mean in-stent late lumen loss was 0.63 ± 0.62 mm for the Yukon Choice stent and 0.45 ± 0.60 mm for the Taxus Liberté stent. Based on the pre-specified margin, the Yukon Choice stent failed to show noninferiority for the primary endpoint. During follow-up, there were no significant differences between groups regarding death, myocardial infarction, stent thrombosis, target lesion revascularization, target vessel revascularization, or nontarget vessel revascularization.


CONCLUSIONS
Compared with the Taxus Liberté stent, the polymer-free sirolimus-eluting Yukon Choice stent failed to show noninferiority with regard to the primary endpoint, in-stent late lumen loss, in patients with diabetes mellitus after 9-month follow-up. Both stents showed comparable clinical efficacy and safety. (Yukon Choice Versus Taxus Liberté in Diabetes Mellitus; NCT00368953).
Validation of a Spanish version of the Revised Fibromyalgia Impact Questionnaire (FIQR)

BACKGROUND
The Revised version of the Fibromyalgia Impact Questionnaire (FIQR) was published in 2009. The aim of this study was to prepare a Spanish version, and to assess its psychometric properties in a sample of patients with fibromyalgia.


METHODS
The FIQR was translated into Spanish and administered, along with the FIQ, the Hospital Anxiety Depression Scale (HADS), the 36-Item Short-Form Health Survey (SF-36), and the Brief Pain Inventory (BPI), to 113 Spanish fibromyalgia patients. The administration of the Spanish FIQR was repeated a week later.


RESULTS
The Spanish FIQR had high internal consistency (Cronbach’s α was 0.91 and 0.95 at visits 1 and 2 respectively). The test-retest reliability was good for the FIQR total score and its function and symptoms domains (intraclass correlation coefficient (ICC > 0.70), but modest for the overall impact domain (ICC = 0.51). Statistically significant correlations (p < 0.05) were also found between the FIQR and the FIQ scores, as well as between the FIQR scores and the remaining scales’ scores.


CONCLUSIONS
The Spanish version of the FIQR has a good internal consistency and our findings support its validity for assessing fibromyalgia patients. It might be a valid instrument to apply in clinical and investigational grounds.
UWB Bowtie Slot Antenna for Breast Cancer Detection

UWB is a very attractive technology for many applications. It provides many advantages such as fine resolution and high power efficiency. Our interest in the current study is the use of UWB radar technique in microwave medical imaging systems, especially for early breast cancer detection. The Federal Communications Commission FCC allowed frequency bandwidth of 3.1 to 10.6 GHz for this purpose. In this paper we suggest an UWB Bowtie slot antenna with enhanced bandwidth. Effects of varying the geometry of the antenna on its performance and bandwidth are studied. The proposed antenna is simulated in CST Microwave Studio. Details of antenna design and simulation results such as return loss and radiation patterns are discussed in this paper. The final antenna structure exhibits good UWB characteristics and has surpassed the bandwidth requirements. Keywords—Ultra Wide Band (UWB), microwave imaging system, Bowtie antenna, return loss, impedance bandwidth enhancement.

Escitalopram in the acute treatment of depressed patients aged 60 years or older.

OBJECTIVE
The present study examined the efficacy and tolerability of acute escitalopram treatment in depressed patients aged 60 years or older.


METHODS
Patients aged > or =60 years with Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition major depressive disorder were randomized to 12 weeks of double-blind, flexible-dose treatment with escitalopram (10-20 mg/day; N = 130) or placebo (N = 134). The prospectively defined primary efficacy end point was change from baseline to week 12 in Montgomery-Asberg Depression Rating Scale (MADRS) total score using the last observation carried forward approach.


RESULTS
A total of 109 (81%) patients in the placebo group and 96 (74%) patients in the escitalopram group completed treatment. Mean age in both groups was approximately 68 years. Mean baseline MADRS scores were 28.4 and 29.4 for the placebo and escitalopram treatment groups, respectively. Escitalopram did not achieve statistical significance compared with placebo in change from baseline on the MADRS (least square mean difference: -1.34; last observation carried forward). Discontinuation rates resulting from adverse events were 6% for placebo and 11% for escitalopram. Treatment-emergent adverse events reported by >10% of patients in the escitalopram group were headache, nausea, diarrhea, and dry mouth.


CONCLUSIONS
Escitalopram treatment was not significantly different from placebo treatment on the primary efficacy measure, change from baseline to week 12 in MADRS. In patients aged 60 years or older with major depression, acute escitalopram treatment appeared to be well tolerated.
Push and rotate: cooperative multi-agent path planning

In cooperative multi-agent path planning, agents must move between start and destination locations and avoid collisions with each other. Many recent algorithms require some sort of restriction in order to be complete, except for the Push and Swap algorithm [7], which claims only to require two unoccupied locations in a connected graph. Our analysis shows, however, that for certain types of instances Push and Swap may fail to find a solution. We present the Push and Rotate algorithm, an adaptation of the Push and Swap algorithm, and prove that by fixing the latter’s shortcomings, we obtain an algorithm that is complete for the class of instances with two unoccupied locations in a connected graph. In addition, we provide experimental results that show our algorithm to perform competitively on a set of benchmark problems from the video game industry.

Association between family members of dialysis patients and chronic kidney disease: a multicenter study in China

BACKGROUND
Family members of patients with end stage renal disease were reported to have an increased prevalence of chronic kidney disease (CKD). However, studies differentiated genetic and non-genetic family members are limited. We sought to investigate the prevalence of CKD among fist-degree relatives and spouses of dialysis patients in China.


METHODS
Seventeen dialysis facilities from 4 cities of China including 1062 first-degree relatives and 450 spouses of dialysis patients were enrolled. Sex- and age- matched controls were randomly selected from a representative sample of general population in Beijing. CKD was defined as decreased estimated glomerular (eGFR<60 mL/min/1.73 m2) or albuminuria.


RESULTS
The prevalence of eGFR less than 60 mL/min/1.73 m2, albuminuria and the overall prevalence of CKD in dialysis spouses were compared with their counterpart controls, which was 3.8% vs. 7.8% (P<0.01), 16.8% vs. 14.6% (P=0.29) and 18.4% vs. 19.8% (P=0.61), respectively. The prevalence of eGFR less than 60 mL/min/1.73 m2, albuminuria and the overall prevalence of CKD in dialysis relatives were also compared with their counterpart controls, which was 1.5% vs. 2.4% (P=0.12), 14.4% vs. 8.4% (P<0.01) and 14.6% vs. 10.5% (P<0.01), respectively. Multivariable Logistic regression analysis indicated that being spouses of dialysis patients is negatively associated with presence of low eGFR, and being relatives of dialysis patients is positively associated with presence of albuminuria.


CONCLUSIONS
The association between being family members of dialysis patients and presence of CKD is different between first-degree relatives and spouses. The underlying mechanisms deserve further investigation.
A PSO and Pattern Search based Memetic Algorithm for SVMs Parameters Optimization

7 Addressing the issue of SVMs parameters optimization, this study proposes an efficient 8 memetic algorithm based on Particle Swarm Optimization algorithm (PSO) and Pattern Search 9 (PS). In the proposed memetic algorithm, PSO is responsible for exploration of the search space 10 and the detection of the potential regions with optimum solutions, while pattern search (PS) is 11 used to produce an effective exploitation on the potential regions obtained by PSO. Moreover, a 12 novel probabilistic selection strategy is proposed to select the appropriate individuals among the 13 current population to undergo local refinement, keeping a well balance between exploration and 14 exploitation. Experimental results confirm that the local refinement with PS and our proposed 15 selection strategy are effective, and finally demonstrate effectiveness and robustness of the 16 proposed PSO-PS based MA for SVMs parameters optimization. 17 18
Applying Graph theory to the Internet of Things

In the Internet of Things (IoT), we all are ``things''. Graph theory, a branch of discrete mathematics, has been proven to be useful and powerful in understanding complex networks in history. By means of graph theory, we define new concepts and terminology, and explore the definition of IoT, and then show that IoT is the union of a topological network, a data-functional network and a domi-functional network.
Optimal Sizing of a Hybrid Grid-Connected Photovoltaic and Wind Power System 1

Escola d’Enginyeria d’Igualada, Universitat Politècnica de Catalunya, Pla de la Massa 8, 08700 Igualada, Spain 3 *Corresponding author. Tel.: +34 938035300; fax: +34 938031589. E-mail address: jordi.riba@eei.upc.edu 4 5 Abstract—Hybrid renewable energy systems (HRES) have been widely identified as an efficient mechanism 6 to generate electrical power based on renewable energy sources (RES). This kind of energy generation 7 systems are based on the combination of one or more RES allowing to complement the weaknesses of one 8 with strengths of another and, therefore, reducing installation costs with an optimized installation. To do so, 9 optimization methodologies are a trendy mechanism because they allow attaining optimal solutions given a 10 certain set of input parameters and variables. This work is focused on the optimal sizing of hybrid grid11 connected photovoltaic – wind power systems from real hourly wind and solar irradiation data and electricity 12 demand from a certain location. The proposed methodology is capable of finding the sizing that leads to a 13 minimum life cycle cost of the system while matching the electricity supply with the local demand. In the 14 present article, the methodology is tested by means of a case study in which the actual hourly electricity retail 15 and market prices have been implemented to obtain realistic estimations of life cycle costs and benefits. A 16 sensitivity analysis that allows detecting to which variables the system is more sensitive has also been 17 performed. Results presented show that the model responds well to changes in the input parameters and 18 variables while providing trustworthy sizing solutions. According to these results, a grid-connected HRES 19 consisting of photovoltaic (PV) and wind power technologies would be economically profitable in the studied 20 rural township in the Mediterranean climate region of central Catalonia (Spain), being the system paid off 21 after 18 years of operation out of 25 years of system lifetime. Although the annual costs of the system are 22 notably lower compared with the cost of electricity purchase, which is the current alternative, a significant 23 upfront investment of over $10M – roughly two thirds of total system lifetime cost – would be required to 24 install such system. 25 26 Keywords—Grid-connected hybrid renewable energy system, life-cycle cost, sizing optimization, solar 27 photovoltaic power, wind power 28 29
Betalain producing cell cultures ofBeta vulgaris L. var. bikores monogerm (red beet)

The betalains are a class of natural pigments comprising the yellow betaxanthins and the violet betacyanins. Callus lines developed fromBeta vulgaris, L. var. bikores monogerm exhibited cell colors ranging from white/green (nonpigmented) through yellow, orange, red, and violet and were representative of all betalain pigments found in the whole plant. The betalains have gained particular interest from the food industry as potential natural alternatives to synthetic food colorants in use today. Red beet extracts (E162), which contain significant amounts of the betacyanins, are currently used in products such as yogurts and ice creams. We describe here the characteristics of culture growth and betalain production for cell suspensions derived from the orange (predominantly betaxanthin-producing) and violet (betacyanin producing) callus lines. The major factors affecting betalain biosynthesis in both cultured and whole plant tissues are reviewed.
Cognitive function and neurodevelopmental outcomes in HIV-infected Children older than 1 year of age randomized to early versus deferred antiretroviral therapy: the PREDICT neurodevelopmental study.

BACKGROUND
We previously reported similar AIDS-free survival at 3 years in children who were >1 year old initiating antiretroviral therapy (ART) and randomized to early versus deferred ART in the Pediatric Randomized to Early versus Deferred Initiation in Cambodia and Thailand (PREDICT) study. We now report neurodevelopmental outcomes.


METHODS
Two hundred eighty-four HIV-infected Thai and Cambodian children aged 1-12 years with CD4 counts between 15% and 24% and no AIDS-defining illness were randomized to initiate ART at enrollment ("early," n = 139) or when CD4 count became <15% or a Centers for Disease Control (CDC) category C event developed ("deferred," n = 145). All underwent age-appropriate neurodevelopment testing including Beery Visual Motor Integration, Purdue Pegboard, Color Trails and Child Behavioral Checklist. Thai children (n = 170) also completed Wechsler Intelligence Scale (intelligence quotient) and Stanford Binet Memory test. We compared week 144 measures by randomized group and to HIV-uninfected children (n = 319).


RESULTS
At week 144, the median age was 9 years and 69 (48%) of the deferred arm children had initiated ART. The early arm had a higher CD4 (33% versus 24%, P < 0.001) and a greater percentage of children with viral suppression (91% versus 40%, P < 0.001). Neurodevelopmental scores did not differ by arm, and there were no differences in changes between arms across repeated assessments in time-varying multivariate models. HIV-infected children performed worse than uninfected children on intelligence quotient, Beery Visual Motor Integration, Binet memory and Child Behavioral Checklist.


CONCLUSIONS
In HIV-infected children surviving beyond 1 year of age without ART, neurodevelopmental outcomes were similar with ART initiation at CD4 15%-24% versus <15%, but both groups performed worse than HIV-uninfected children. The window of opportunity for a positive effect of ART initiation on neurodevelopment may remain in infancy.
American ginseng (Panax quinquefolius) administration does not affect performance of the Roche COBAS Ampliprep/Taqman HIV-1 RNA assay

BACKGROUND
Previous data indicate that purified components of ginseng can inhibit HIV reverse transcriptase in vitro, suggesting that ginseng components in plasma may interfere with HIV-1 RNA detection assays.


METHODS
Pre- and post-dose plasma from three volunteers dosed with 3000 mg American ginseng was spiked with HIV and analyzed by the Roche COBAS Ampliprep/Taqman v2.0 HIV-1 RNA assay.


RESULTS
Presence of American ginseng had no significant effect on measured HIV-1 RNA concentration. Variation within pre- and post-dose plasma pair was insignificant and within assay performance limits.


CONCLUSION
Plasma from subjects dosed with 3000 mg American ginseng does not interfere with the Roche COBAS Ampliprep/Taqman v2.0 HIV-1 RNA assay. This implies that in vitro inhibition of HIV reverse transcriptase by American ginseng components is unlikely to be clinically relevant.
Objectives, design and enrollment results from the Infant Susceptibility to Pulmonary Infections and Asthma Following RSV Exposure Study (INSPIRE)

BACKGROUND
Respiratory syncytial virus (RSV) lower respiratory tract infection (LRI) during infancy has been consistently associated with an increased risk of childhood asthma. In addition, evidence supports that this relationship is causal. However, the mechanisms through which RSV contributes to asthma development are not understood. The INSPIRE (Infant Susceptibility to Pulmonary Infections and Asthma Following RSV Exposure) study objectives are to: 1) characterize the host phenotypic response to RSV infection in infancy and the risk of recurrent wheeze and asthma, 2) identify the immune response and lung injury patterns of RSV infection that are associated with the development of early childhood wheezing illness and asthma, and 3) determine the contribution of specific RSV strains to early childhood wheezing and asthma development. This article describes the INSPIRE study, including study aims, design, recruitment results, and enrolled population characteristics.


METHODS/DESIGN
The cohort is a population based longitudinal birth cohort of term healthy infants enrolled during the first months of life over a two year period. Respiratory infection surveillance was conducted from November to March of the first year of life, through surveys administered every two weeks. In-person illness visits were conducted if infants met pre-specified criteria for a respiratory illness visit. Infants will be followed annually to ages 3-4 years for assessment of the primary endpoint: wheezing illness. Nasal, urine, stool and blood samples were collected at various time points throughout the study for measurements of host and viral factors that predict wheezing illness. Nested case-control studies will additionally be used to address other primary and secondary hypotheses.


DISCUSSION
In the INSPIRE study, 1952 infants (48% female) were enrolled during the two enrollment years and follow-up will continue through 2016. The mean age of enrollment was 60 days. During winter viral season, more than 14,000 surveillance surveys were carried out resulting in 2,103 respiratory illness visits on 1189 infants. First year follow-up has been completed on over 95% percent of participants from the first year of enrollment. With ongoing follow-up for wheezing and childhood asthma outcomes, the INSPIRE study will advance our understanding of the complex causal relationship between RSV infection and early childhood wheezing and asthma.

Frontal brain dysfunction in alcoholism with and without antisocial personality disorder

Alcoholism and antisocial personality disorder (ASPD) often are comorbid conditions. Alcoholics, as well as nonalcoholic individuals with ASPD, exhibit behaviors associated with prefrontal brain dysfunction such as increased impulsivity and emotional dysregulation. These behaviors can influence drinking motives and patterns of consumption. Because few studies have investigated the combined association between ASPD and alcoholism on neuropsychological functioning, this study examined the influence of ASPD symptoms and alcoholism on tests sensitive to frontal brain deficits. The participants were 345 men and women. Of them, 144 were abstinent alcoholics (66 with ASPD symptoms), and 201 were nonalcoholic control participants (24 with ASPD symptoms). Performances among the groups were examined with Trails A and B tests, the Wisconsin Card Sorting Test, the Controlled Oral Word Association Test, the Ruff Figural Fluency Test, and Performance subtests of the Wechsler Adult Intelligence Scale. Measures of affect also were obtained. Multiple regression analyses showed that alcoholism, specific drinking variables (amount and duration of heavy drinking), and ASPD were significant predictors of frontal system and affective abnormalities. These effects were different for men and women. The findings suggested that the combination of alcoholism and ASPD leads to greater deficits than the sum of each.
