Entrepreneurial aspirations: a five country study

Entrepreneurial research has identified a number of personal characteristics considered to be important in inducing entrepreneurial activities. Among those personal traits considered to be important are locus of control and innovativeness. This study focuses on the personal traits of locus of control and innovativeness and examines their impact on third and fourth year business students’ aspirations to become an entrepreneur. A multiple regression analysis was conducted between the personality traits of locus of control and innovation as independent variables and the decision to build a business from scratch as the dependent variable measuring entrepreneurial aspirations. The results suggest that both locus of control and innovation are significant predictors of entrepreneurial aspirations when measured by the decision to build a business from scratch.
The Value of Selective IT Sourcing

Why does the outsourcing of IT frequently fail to produce the expected cost savings or other benefits? Perhaps because managers don't carefully select which IT activities to outsource. The authors examined sixty-two sourcing decisions at forty organizations through interviews with senior business executives, CIOs, consultants, and vendor account managers. From their data, they developed a set of frameworks to clarify sourcing options and aid managers in deciding which IT functions to contract out and which to retain in-house.
Trading on Fluffy News: The Effect of Information Tangibility on Short Sellers’ Behavior

We investigate how short sellers strategically exploit the liquidity generated by the arrival of ambiguous information – i.e. information likely to cause disagreement in interpretation. Using a sample of newspaper articles, media newswires, and press releases, we construct a measure of information tangibility as the ratio of numbers to the total words in an article. First, we show that noise trading increases in the presence of “fluffy” news – i.e. news which has little numerical content. Measures of stock liquidity increase and the news-day return mean-reverts more on days with intangible news releases. Second, we find that short sellers exploit this increase in noise trading to place their informed trades. Moreover, intangibility has a bigger effect on short sellers’ trading after an exogenous decrease in liquidity following a deletion of the stock from the S&P 500 index. At the same time, it has a lower effect when investor attention is more distracted otherwise – e.g. during significant sporting events. We rule out the alternative explanation of short sellers’ superior ability to interpret qualitative news by showing that their trades on days with such news do not predict future stock returns better. Overall, our results indicate that short sellers exploit additional liquidity around media events to place their informed trades.
Combined Effects of Curcumin and Lycopene or Bixin in Yoghurt on Inhibition of LDL Oxidation and Increases in HDL and Paraoxonase Levels in Streptozotocin-Diabetic Rats

Combination therapy using natural antioxidants to manage diabetes mellitus and its complications is an emerging trend. The aim of this study was to investigate the changes promoted by treatment of streptozotocin (STZ)-diabetic rats with yoghurt enriched with the bioactives curcumin, lycopene, or bixin (the latter two being carotenoids). Antioxidants were administered individually, or as mixtures, and biomarkers of metabolic and oxidative disturbances, particularly those associated with cardiovascular risk, were assessed. Treatment of STZ-diabetic rats with natural products individually decreased glycemia, triacylglycerol, total-cholesterol, oxidative stress biomarkers, including oxidized low-density lipoprotein (ox-LDL), and increased the activities of antioxidant enzymes. Individual carotenoids increased both high-density lipoprotein (HDL) and paraoxonase levels, whereas curcumin increased only paraoxonase. Treatments with mixtures of curcumin and lycopene or bixin had combined effects, decreasing biomarkers of carbohydrate and lipid disturbances (curcumin effect), increasing the HDL levels (carotenoids effects) and mitigating oxidative stress (curcumin and carotenoids effects). The combined effects also led to prevention of the LDL oxidation, thereby mitigating the cardiovascular risk in diabetes. These findings provide evidence for the beneficial effect of curcumin and carotenoid mixtures as a supplementation having antioxidant and antiatherogenic potentials, thus appearing as an interesting strategy to be studied as a complementary therapy for diabetic complications.
Prioritization of Critical Success Factors in Knowledge-Management Using the AHP Method

Abstract. Knowledge Management (KM) plays an important role in today’s enterprise management and implementation of KM takes a considerable time and resources from the organization. Therefore, it is essential that critical success factors (CSFs) of KM are identified and prioritized. According to what was said, the main purpose of this paper is: Identification and prioritization of CSFs in the KM in small and medium-sized enterprises (SMEs) in Iran. According to this objective, two steps are provided: in the first step the authors initially use a related topic of CSFs in KM implementation, which aims at identifying and investigating factors that result in more successful KM systems implementation that generate higher levels of value for organizations. By integrating insights drawn from these studies, the authors proposed a set of 12 CSFs which is believed to be more suitable for SMEs. Then, in the second step, these factors will be prioritized by analytic hierarchy process (AHP).
Probably Approximate Learning Over Classes of Distributions

This paper presents algorithms that construct approximations to sets and functions on the reals, from randomly chosen sample points. The model that is analyzed is a generalization of the paradigm of probably approximate learning proposed by Valiant. Previously, necessary and sufficient conditions for learning sets were established for the case when the class of sampling distributions is finite, and for the case when the class of sampling distributions is the set of all possible distributions. Here, sufficient conditions are obtained for learning sets and functions over general classes of sampling distributions. The results for functions are with respect to general metrics for measuring the distance between two functions.
Do IPOs underperform in the long run? Evidence from the Johannesburg Securities Exchange (JSE)

This article examines the three-, five- and ten-year long-run performance of initial public offerings (IPOs) on the Johannesburg Securities Exchange (JSE). The Buy and Hold Abnormal Return (BHAR) and the Cumulative Abnormal Return (CAR) methods were used to calculate the IPO long-run performance. Using a sample of 313 companies listed for the period 1996– 2007, this study established that IPOs on the (JSE) underperformed the market over three years (by 65.59% and 59.77% for BHAR and CAR respectively) and five years (by 64.37% and 7.77% for BHAR and CAR respectively). Also observed was that IPOs on the JSE outperform the market over a ten-year period when using the CAR (116.23%). Furthermore, the three-, five- and ten-year BHAR in the JSE were affected by the market period, which had no significant impact on the CAR. These findings basically stress the effect the different benchmarks and methodologies have when calculating the long-run performance of IPOs. Although IPOs underperform the market over a five-year period from the first trading day, the yearly performance of most of these companies from their fourth trading year is positive. As such, investors are advised to stay out of the stock market within the first three years, but in the fourth year they are encouraged to invest and buy mainly portfolios comprising companies that have been trading for at least four years.

THE INFLUENCE OF BRAND IMAGE AND CUSTOMER VALUE ON CUSTOMER LOYALTY OF NOKIA HIGH-END IN BANDUNG

Blackberry has already changed the competition especially in Indonesia smart phone market. And Nokia, as market leader in Indonesia cellular phone market, got the impact of this situation. Along this year, customer whom used Nokia as their cell phone, tend to change their cell phone to Blackberry. The aim of this research is to understand The Influence brand image and customer value on customer loyalty of Nokia High-end in Bandung. The qualitative, descriptive, verificative analysis method is used in this research to discover brand image, customer value and customer loyalty. This research also used the explanatory method to find out brand image and customer value on customer loyalty of Nokia High-end in Bandung. The result showed that both variable signficantly influenced the customer loyalty. And both of them have similar impact. Beside that, Nokia has a good image, and their customer value are in the high level and also their customer loyal to them. Innovation could be done by the improvement of the fitur and benefit that their competitors have such as BlackBerry for example the BlackBerry Massenger fitur. Chatting facility (Nokia Messenger Facility) with all the Nokia’s owner in certain types could make Nokia more competitive to their competitors such as BlackBerry. Improvement in product and service quality especially in accuracy and effectiveness of service would be usefull for Nokia to keep their customer loyalty. Eventhough it is already good at service, but speed of service and the accuracy still the pin point of the customer. Another variables such as the product mix, customer relation management (CRM) can be used in the next research to discover the customer loyalty.
DXT: Darshan eXtended Tracing

Author(s): Xu, Cong; Snyder, Shane; Kulkarni, Omkar; Venkatesan, Vishwanath; Carns, Phillip; Byna, Surendra; Sisneros, Robert; Chadalavada, Kalyana | Abstract: As modern supercomputers evolve to exascale, their I/O subsystems are becoming increasingly complex, making optimization of I/O for scientific applications a daunting task. Although I/O profiling tools facilitate the process of optimizing application I/O performance, legacy profiling tools lack flexibility in their level of detail and ability to correlate traces with other sources of data. Additionally, a lack of robust trace analysis tools makes it difficult to derive actionable insights from large-scale I/O traces. Darshan is an HPC I/O characterization tool that records statistics in a lightweight manner that makes it appropriate for full-time production deployment. However, Darshan’s default characterization mechanism records information at a fixed granularity. We augment Darshan by proposing Darshan eXtended Tracing (DXT) for more detailed profiling of I/O software stacks. DXT enables users and administrators to vary the level of fidelity captured by Darshan at run time without modifying or recompiling applications. This capability facilitates systematic analysis on the I/O behavior of applications and can provide useful application kernel I/O traces to help advance parallel I/O research. We have demonstrated the power of DXT by obtaining a wide range of useful statistics for multiple case studies, and we further show that DXT is able to do so same with negligible overhead.
Using Perceived Exertion to Prescribe and Monitor Exercise Training Heart Rate

We examined whether feedback of heart rate (HR) or HR combined with ratings of perceived exertion (RPE and HR) during a graded exercise test (GXT) and during early trials of field training would reduce the errors commonly seen when training heart rate range (THR) is self-monitored by participants. Asymptomatic males (n = 24) were tested on a Balke treadmill protocol in a randomized, between-groups design under control conditions or conditions where feedback about HR or HR combined with RPE were given as age-predicted THR was approximated. This was followed on alternating days by three field trials of an 800-m jog where errors between prescribed and attained THR were fed back to each subject. A priori 95% confidence intervals for the first field trial showed that signed (algebraic) error for the HR combined with RPE condition (+3 bts/min) was less than for controls (+23.5 bts/min). Feedback of HR alone was no different from the control condition. All groups showed increased accuracy (P less than .05) by the third field trial [absolute error: T1 (18 bts/min) to T3 (9.6 bts/min); signed error: T1 (+14 bts/min) to T3 (+4 bts/min)]. Our results suggest feedback of HR combined with RPE during a GXT may reduce an overshoot in THR during the first of subsequent exercise sessions. Feedback of HR alone appeared sufficient to further reduce THR errors after a third exercise session in the field. The procedures used may have practical importance for sedentary, unfit, or diseased individuals where conservative HR prescriptions are desirable but electronic monitoring is not feasible or cost effective.
Nam1p, a Protein Involved in RNA Processing and Translation, Is Coupled to Transcription through an Interaction with Yeast Mitochondrial RNA Polymerase*

Alignment of three fungal mtRNA polymerases revealed conserved amino acid sequences in an amino-terminal region of the Saccharomyces cerevisiae enzyme implicated previously as harboring an important functional domain. Phenotypic analysis of deletion and point mutations, in conjunction with a yeast two-hybrid assay, revealed that Nam1p, a protein involved in RNA processing and translation in mitochondria, binds specifically to this domain. The significance of this interaction in vivo was demonstrated by the fact that the temperature-sensitive phenotype of a deletion mutation (rpo41Δ2), which impinges on this amino-terminal domain, is suppressed by overproducing Nam1p. In addition, mutations in the amino-terminal domain result specifically in decreased steady-state levels of mature mitochondrial CYTBand COXI transcripts, which is a primary defect observed inNAM1 null mutant yeast strains. Finally, one point mutation (R129D) did not abolish Nam1p binding, yet displayed an obviousCOX1/CYTB transcript defect. This mutation exhibited the most severe mitochondrial phenotype, suggesting that mutations in the amino-terminal domain can perturb other critical interactions, in addition to Nam1p binding, that contribute to the observed phenotypes. These results implicate the amino-terminal domain of mtRNA polymerases in coupling additional factors and activities involved in mitochondrial gene expression directly to the transcription machinery.
Factors Limiting Tropical Rain Forest Regeneration in Abandoned Pasture: Seed Rain, Seed Germination, Microclimate, and Soil 1

Vegetation, seed rain, seed germination, microclimate, and soil physical and chemical parameters were measured in a recently abandoned pasture and adjacent primary rain forest in southern Costa Rica. The goal of this study was to assess the importance of these factors in limiting forest regeneration in abandoned pastures. Seed rain of animal dispersed species decreased dramatically in the pasture >5 m from the forest/pasture edge; fewer wind dispersed seeds fell in the pasture than in the forest, but the difference was much less than for animal dispersed seeds. Percent seed germination of most species studied was similar in the forest and in pasture with grasses; seed germination was lower during the dry season in areas of pasture cleared of grasses. Air temperature, vapor pressure deficit (VPD), and photon flux density (PFD) were much higher in the pasture than in the forest at 1 m above the ground. VPD and PFD at ground level and soil temperature were similar in the pasture and the forest, indicating that pasture grasses strongly modify microclimatic conditions near the soil surface. The lowest gravimetric water content recorded in the pasture during the dry season was 0.5 and leaf relative water contents of the two species measured in the forest and pasture were identical, suggesting that plants in the pasture were not water stressed. Levels of most soil nutrients were lower in the pasture as compared to the forest; however, aboveground and root biomass for seedlings grown in pasture and forest soils did not differ significantly. Although a number of factors impede forest recovery in abandoned pastures, these results suggest that the most imporrant limitation is lack of seed dispersal.
Incorporating Functional MR Imaging into Diffusion Tensor Tractography in the Preoperative Assessment of the Corticospinal Tract in Patients with Brain Tumors

BACKGROUND AND PURPOSE: Our goal was to improve the preoperative assessment of the corticospinal tract (CST) in patients with brain tumors. We investigated whether the integration of functional MR imaging (fMRI) data and diffusion tensor (DT) tractography can be used to evaluate the spatial relationship between the hand and foot fibers of the CST and tumor borders. MATERIALS AND METHODS: We imaged 10 subjects: 1 healthy volunteer and 9 patients. Imaging consisted of a 3D T1-weighted sequence, a gradient-echo echo-planar imaging (EPI) sequence for fMRI, and a diffusion-weighted EPI sequence for DT tractography. DT tractography was initiated from a seed region of interest in the white matter area subjacent to the maximal fMRI activity in the precentral cortex. The target region of interest was placed in the cerebral peduncle. RESULTS: In the healthy volunteer, we successfully tracked hand, foot, and lip fibers bilaterally by using fMRI-based DT tractography. In all patients, we could track the hand fibers of the CST bilaterally. In 4 patients who also performed foot tapping, we could clearly distinguish hand and foot fibers. We were able to depict the displacement of hand and foot fibers by tumor and the course of fibers through areas of altered signal intensity. CONCLUSION: Incorporating fMRI into DT tractography in the preoperative assessment of patients with brain tumors may provide additional information on the course of important white matter tracts and their relationship to the tumor. Only this approach allows a distinction between the CST components, while visualization of the CST is improved when fiber tracking is hampered by tumor (infiltration) or perifocal edema.
Lack of Association between ACE I/D and AGTR1 A1166C Gene Polymorphisms and Preeclampsia in Turkish Pregnant Women of Trakya Region

The aim of this study was to investigate the distribution of Angiotensin Converting Enzyme Insertion/Deletion (ACE I/D) and the distribution of Angiotensin II Type 1 Receptor A1166C (AGTR1 A1166C) gene polymorphisms in preeclamptic pregnant women comparing to control pregnant women in Turkish subjects of Trakya Region. We aimed to determine whether these polymorphisms are genetic risk factor for preeclampsia. The study included 75 preeclamptic pregnant women and 75 control pregnant women, which were categorized according to The World Health Organization Detecting Pre-eclampsia: A Practical Guide. The ACE I/D gene polymorphism was investigated using Polymerase Chain Reaction (PCR) method. The AGTR1 A1166C gene polymorphism was identified using PCR and followed by Restriction Fragment Length Polymorphism (RFLP) methods. The ACE I/D genotype distribution in preeclamptic pregnant women DD=36.0%, ID=44.0% and II=20.0% did not significantly differ from those in control pregnant women DD=38.7%, ID=50.7% and II=10.6% (P=0.279). The AGTR1 A1166C genotype distribution in preeclamptic pregnant women AA=57.3%, AC=33.4% and CC=9.3% also did not significantly differ from those in control pregnant women AA=70.7, AC=24.0% and CC=5.3% (P=0.223). This case-control study show that ACE I/D and AGTR1 A1166C gene polymorphisms are not genetic risk factors for preeclampsia in this population in Turkish pregnant women of Trakya Region.
Comparison of evidence‐based therapeutic intervention between community‐ and hospital‐based primary care clinics

The purpose of this study was to compare the proportion of therapeutic interventions that is supported by scientific evidence between hospital‐based and community‐based primary care clinics. The study setting is a primary care clinic in university‐affiliated tertiary hospital and community‐based primary care clinic in a region in Seoul. A retrospective review of patients' medical records was done according to the primary diagnosis and treatment for 890 patients in community‐based clinic and 307 in hospital‐based clinic. The evidence for the intervention was searched for in Medline (1966–2001) and other evidence‐based databases. The evidence was then classified as one of the three categories (i) evidence from randomised controlled trials (RCTs); (ii) convincing non‐experimental evidence; and (iii) interventions without substantial evidence. In the hospital‐based clinics, out of 356 primary diagnosis and treatment pairs, 59.6% were supported by evidence from at least one RCTs, and 19.4% were supported by convincing non‐experimental evidence. In the community‐based clinics, 47.1% out of 893 pairs and 10.5% fell into each category. As a result, the proportion of interventions in community settings that were based on evidence meeting our criteria was significantly lower than that of the hospital‐based settings. To facilitate evidence‐based practice, supportive activity should be focused on the primary care settings based on community where medical practices are less evidence‐based.
Micturition studies in infants and children. Normal urinary flow.

The urinary flow was studied in 216 boys and 180 girls, aged 3 days to 16 years. the individual flow pattern was fairly constant. There were considerable variations between different individuals. the ranges of different flow variables at different micturition volumes are given. With increased micturition volume the flow curve showed a plateau in the age group 4-13 years. This plateau seems to be characteristic for children. the maximum flow was positively correlated to the volume of voided urine, as in adults. in girls no difference between age groups could be demonstrated as regards increase in maximum flow with volume. in boys 0-4 years the increase of maximum flow with volume was more pronounced than in boys aged 4-16 years. Girls 4-16 years showed a more pronounced increase of maximum flow with volume than boys of the same age group—above 70 ml volume their mean maximum flow was on a higher level. An attempt was made to correlate the maximum flow with height, weight, body surface and age, respectively.
Perceived pain and satisfaction with medical rehabilitation after hospital discharge

Objective: To examine the association between pain and satisfaction with medical rehabilitation in patients with hip or knee replacement approximately 90 days after discharge from inpatient medical rehabilitation. Design: A cross-sectional design. Participants: The sample included 2507 patients with hip or knee replacement using information from the IT Health Track medical outcome database. Main outcome measure: Satisfaction with medical rehabilitation. Results: The average age was 70.2 years, 66.5% were female, and 88.5% were non-Hispanic white. Pain scores were significantly and inversely associated with satisfaction with medical rehabilitation after adjustment for possible confounding factors. In patients with hip replacement each one-point increase in pain score was associated with a 10% decreased odds ratio (OR) of being satisfied with medical rehabilitation (OR 0.90, 95% confidence interval (CI) 0.84, 0.96). In patients with knee replacement, each one-point increase in pain score was associated with a 9% decreased odds ratio (OR 0.91, 95% CI 0.87, 0.96) of being satisfied with medical rehabilitation. Conclusion: Our data indicate that postoperative pain from hip or knee replacement is associated with reduced satisfaction with medical rehabilitation. Better postoperative pain control may improve a patient's level of satisfaction.
