Motivators for the intention to use mobile TV

This research tests the effects of gender on attitude and intention to use mobile TV. Gender is frequently identified as a key moderating variable in consumers’ behaviour and in the usage of media. Studying the case of mobile TV in the early stage of Korean digital multimedia broadcasting (DMB) development is important because Korea is the first market where mobile TV is commercially available. The findings can provide useful implications not only for theory in the adoption of new media but also for marketing practitioners in countries that are rolling out mobile TV. Five motivation factors – entertainment, social interaction, permanent access, pass time and fashion/status – were drawn from uses and gratifications theory to test their relationship with attitude and intention to use mobile TV. For the purposes of the study, a total of 256 undergraduate students in South Korea participated in the survey. Overall, uses and gratifications theory is found to be a valid approach to explain people’s attitude and intention to use a mobile TV. Regarding gender effects, the results indicate that motivation for fashion/status is most important for males, while social interaction has the highest impact on female attitude and intention. Theoretical and practical implications are offered; they suggest that the advertising concept needs to be targeted by consumers’ gender.
The Effect of 9-Ending Prices on Retail Sales: A Quantitative UK Based Field Study

Surveys suggest that around 64% of retail shelf prices end in 9: The preponderance of 9-ending prices is not a new phenomenon and has been the subject of much comment and discussion over the past 70 years. Despite this broad interest, very few empirically based studies have been conducted in order to assess the effectiveness of the practice; no quantitative study can be found that has assessed the reaction of UK consumers toward 9-ending prices. In this paper we present the results of a large-scale store-based trial in which a selection of product prices were rounded up from the retailers' traditional 9-ending prices to round-pound prices. The results from this research suggest that the adoption of round-pound prices may be more effective, with trial sales increasing. The data yields an interesting insight into the effectiveness of the practice, and provides clear indication of the value further research in this area would bring.
Radiologic measurements associated with the prognosis and need for surgery in patients with subchondral insufficiency fractures of the femoral head.

OBJECTIVE The objective of this study was to identify the risk factors associated with the prognosis and need for surgery of patients with subchondral insufficiency fractures of the femoral head. MATERIALS AND METHODS Twenty-nine consecutively registered patients with subchondral insufficiency fractures of the femoral head were divided into the two groups: a non-progression of collapse group, which included patients who had no collapse or 2 mm or less of collapse of the femoral head and whose symptoms resolved (14 patients), and a progression of collapse group, which included patients who had more than 2 mm of collapse, for which surgery was indicated (15 patients). Both groups received the same conservative therapy. The following radiographic measurements were obtained: Sharp angle, center edge angle, acetabular roof angle, and acetabular head index. On MR images, band length, defined as the length of a low-signal-intensity band in the coronal plane, and band length ratio, defined as the proportion of the band length relative to the weight bearing portion, were assessed for each patient. Bone mineral density measurements (T score) were available for 17 patients. RESULTS In the univariate analyses, T score, Sharp angle, center edge angle, acetabular roof angle, acetabular head index, band length, and band length ratio were found to be significant prognostic factors. Multivariate analyses of T score, acetabular head index, and band length ratio showed that both acetabular head index and band length ratio were significant predictors. CONCLUSION Both acetabular head index and band length ratio are important prognostic factors in the care of patients with subchondral insufficiency fractures of the femoral head.
“Pore-Like” Effects of Super-Molecular Self-Assembly on Molecular Diffusion of Poly(Ethylene Oxide)-Poly(Propylene Oxide)-Poly(Ethylene Oxide) in Water

Molecular diffusion of triblock copolymers poly(ethylene oxide)-poly(propylene oxide)-poly(ethylene oxide) in water was studied with the help of Pulsed Field Gradient NMR in the broad range of polymer weight fractions from 0.09 to 0.8. Owing to amphiphilic nature of the molecules, these block copolymers exhibit rich self-organization properties when mixed with water. In particular, at ambient temperatures they form micelles and three liquid crystalline mesophases: cubic, hexagonal, and lamellar. The corresponding super-molecular structure formations were studied with the same block copolymer and at the same temperature. Self-assembly of molecules was shown to produce “pore-like” effects on their self-diffusion properties by imposing severe constraints on the dimensionality of propagation. Diffusion in the hexagonal phase was shown to be quasi one-dimensional in the direction parallel to the long axis of the ordered molecular rods. In the lamellar phase, diffusion was found to be quasi two-dimensional, in the plane of the lamellar structures. The observed diffusion anisotropy was attributed to the effects of the specific molecular ordering on the mesoscopic length scale.
Placental Growth Factor (PlGF) Is a Surrogate Marker in Preeclamptic Hypertension

Objective: To evaluate plasma levels of angiogenic factors and their association with preeclampsia. Methods: Twenty-three women with preeclampsia and nine normotensive pregnant women from the Maternity of Hospital das Clínicas of Belo Horizonte/MG-Brazil were assessed by National High Blood Pressure Education Program Working Group Creteria (NHBPEPWG). The plasma levels of vascular endothelial growth factor (VEGF) and Placental growth factor (PlGF) were determined by ELISA assay. Results: Plasma concentration of PlGF was 12-fold lower in preeclampsia versus non preeclampsia pregnancies. An inverse correlation was observed between PlGF plasma levels and mean arterial pressure (MAP); a decrease in 1pg/mL of PlGF resulted in 6.18 mm Hg increase in MAP. Conclusion: These results indicate that PlGF is related to MAP in pregnant women.
Cognitive Activities and Levels of Abstraction in Procedural and Object-Oriented Design

The research reported in this article provides descriptions of design activities and of the evolving designs for expert procedural and expert object-oriented (OO) designers and for novice OO designers who also had extensive procedural experience. Ten experienced programmers were observed while designing software that would serve as a scoring system for swim meet competitions. Talk-aloud protocols were collected and analyzed for different types of cognitive activities and strategies that occurred during the course of design. In particular, we analyzed both the design activities and the level of abstraction of the designs over the course of time for each group in order to examine the role of several design strategies described in the literature as central in procedural design. In the course of these analyses, we developed a generic way (design template) of comparing the final designs of designers in different paradigms. Using this template, we analyzed the designs in terms of their completeness for different views at different levels of abstraction. Our analyses of procedural and OO designers-in terms of their cognitive activities, design strategies, and final designs-provide a detailed comparison between design paradigms in practice. A variety of descriptive results are discussed in terms of positive transfer, interference, and implications for design training. Findings are also discussed in terms of the relation between tasks and design paradigms.
PENGARUH BRAND IMAGE DAN BRAND TRUST TERHADAP BRAND LOYALTY PADA PT BANK SINARMAS

Competition in the banking sector in Indonesia is getting more and more fierceevery day. PT Bank Sinarmas is a rapidly growing bank that continues to increase for the last 3 years. PT Bank Sinarmas committed to maintain this position. Therefore, they need to provide excellent service and deliver good quality savings products to build customer loyalty. The purpose of this study was to determine whether brand image (X1) and brand trust (X2) are partially influencing brand loyalty (Y), and to determine whether both brand image (X1) and brand trust (X2) are simultaneously influencing brand loyalty (Y). The analysis method used is multiple regression analysis using SPSS. Data is obtained through direct survey by distributing questionnaires to 100 clients of the bank at the main branch. The results indicates that the company's brand image significantly influences brand loyalty with R2 = 15.4% with regression equation Y = 1.962 +0.336 X1. Brand trust significantly influences brand loyalty with R2 = 17%, with regression equation Y = 1.838 +0.382 X2. While simultaneously, brand image and brand trust significantly influence brand loyalty, with R2 = 26.4% which form the regression equation Y = 1.281 +0.269 X1 + . 315 X2. Thus, PT Bank Sinarmas needs to increase its brand image since a good image might become the company's competitive edge in creating loyalty, and subsequently loyalty will increase profitability.
Consensus on strategy formulation and organizational performance: Competitors in a fragmented industry

This paper examines the relationship between organizational performance and consensus (or agreement) within top management teams on company objectives and competitive methods for a sample of nineteen firms competing within a highly fragmented industry—paints and allied products (SIC 2851). It was hypothesized that intense competitive pressures and the resultant low industry profitability would constrain organizational resources and augment the need for consensus on both objectives and methods. However, findings indicate that consensus on either objectives or methods is positively related to organizational performance.
Influence of temple headache frequency on physical functioning and emotional functioning in subjects with temporomandibular disorder pain.

AIMS To investigate the relationship of headache frequency with patient-reported physical functioning and emotional functioning in temporomandibular disorder (TMD) subjects with concurrent temple headache. METHODS The Research Diagnostic Criteria for TMD (RDC/TMD) Validation Project identified, as a subset of 614 TMD cases and 91 controls (n = 705), 309 subjects with concurrent TMD pain diagnoses (RDC/TMD) and temple headache. The temple headaches were subdivided into infrequent, frequent, and chronic headache according to the International Classification of Headache Disorders, second edition (ICHD-II). Study variables included self-report measures of physical functioning (Jaw Function Limitation Scale [JFLS], Graded Chronic Pain Scale [GCPS], Short Form-12 [SF-12]) and emotional functioning (depression and anxiety as measured by the Symptom Checklist-90R/SCL-90R). Differences among the three headache subgroups were characterized by increasing headache frequency. The relationship between ordered headache frequency and physical as well as emotional functioning was analyzed using linear regression and trend tests for proportions. RESULTS Physical functioning, as assessed with the JFLS (P < .001), SF-12 (P < .001), and GCPS (P < .001), was significantly associated with increased headache frequency. Emotional functioning, reflected in depression and anxiety, was also associated with increased frequency of headache (both P < .001). CONCLUSION Headache frequency was substantially correlated with reduced physical functioning and emotional functioning in subjects with TMD and concurrent temple headaches. A secondary finding was that headache was precipitated by jaw activities more often in subjects with more frequent temple headaches.
Cap-assisted colonoscopy versus standard colonoscopy: is the cap beneficial? A meta-analysis of randomized controlled trials

Background: In an effort to improve visualization during colonoscopy, a transparent plastic cap or hood may be placed on the end of the colonoscope. Cap-assisted colonoscopy (CAC) has been studied and is thought to improve polyp detection. Numerous studies have been conducted comparing pertinent clinical outcomes between CAC and standard colonoscopy (SC) with inconsistent results. Methods: Numerous databases were searched in November 2016. Only randomized controlled trials (RCTs) involving adult subjects that compared CAC to SC were included. Outcomes of total colonoscopy time, time to cecum, cecal intubation rate, terminal ileum intubation rate, polyp detection rate (PDR), and adenoma detection rate (ADR) were analyzed in terms of odds ratio (OR) or mean difference (MD) with fixed effect and random effects models. Results: Five hundred eighty-nine articles and abstracts were discovered. Of these, 23 RCTs (n=12,947) were included in the analysis. CAC showed statistically significant superiority in total colonoscopy time (MD -1.51 min; 95% confidence interval [CI] -2.67 to -0.34; P<0.01) and time to cecum (MD -0.82 min; 95%CI -1.20 to -0.44; P<0.01) compared to SC. CAC also showed better PDR (OR 1.17; 95%CI 1.06-1.29; P<0.01) but not ADR (OR 1.11; 95%CI 0.95-1.30; P=0.20). In contrast, on sensitivity analysis, ADR was better with CAC. Terminal ileum intubation and cecal intubation rates demonstrated no significant difference between the two groups (P=0.11 and P=0.73, respectively). Conclusions: The use of a transparent cap during colonoscopy improves PDR while reducing procedure times. ADR may improve in cap-assisted colonoscopy but further studies are required to confirm this.
Treatment of ocular melanoma metastatic to the liver by hepatic arterial chemotherapy.

PURPOSE Ocular melanoma is characterized by a high rate of liver metastases and is associated with a median survival time less than 5 months. There is no standard treatment available. Treatment strategies have, without success, relied on the experience with metastatic cutaneous melanoma. The only effective treatment is chemoembolization using cisplatin and polyvinyl sponge, which has never become accepted on a large scale. The objective of the study was to establish prospectively the efficacy and toxicity of hepatic intraarterial fotemustine, a third-generation nitrosourea, in patients with liver metastases from ocular melanoma. PATIENTS AND METHODS Thirty-one patients were subjected to laparotomy to place a totally implantable catheter into the hepatic artery and received fotemustine 100 mg/m2 as a 4-hour infusion, first once a week for four times and then, after a 5-week rest period, every 3 weeks until progression or toxicity. Cox regression models were used to assess the prognostic role of patient survival characteristics. RESULTS Objective responses were observed in 12 of 30 assessable patients (40%; 95% confidence interval, 22% to 59%). The median duration of response was 11 months and the median overall survival time, 14 months. Lactate dehydrogenase (LDH) appeared to be the strongest prognostic factor for survival. Toxicity was minimal and treatment could be administered on an outpatient basis. CONCLUSION The results of hepatic arterial chemotherapy with fotemustine produced a high response rate and survival similar to chemoembolization therapy. It involves no major toxicity and preserves the quality of life. To assess further its effectiveness, a randomized study to compare hepatic intraarterial versus intravenous chemotherapy is being planned.
The presence of linoleic acid in Escherichia coli cannot be confirmed

Escherichia coli was recently reported to accumulate significant quantities of linoleic acid in stationary phase (H. Rabinowitch, D. D. Sklan, D. H. Chace, R. D. Stevens, and I. Fridovich, J. Bacteriol. 175:5324-5328, 1993). Since this finding would have considerable impact on the biochemical mechanisms of type II fatty acid synthases, we have attempted to confirm this observation. We found no evidence for the accumulation of linoleic acid in late-stationary-phase cultures of E. coli and conclude that the results of Rabinowitch et al. are artifactual.
From Small Business to Entrepreneurship Policy

This unique Handbook provides a solid foundation for essential study in the nascent field of entrepreneurship policy research. This foundation is initially developed via the exploration of two significant propositions underpinning the nature of entrepreneurship policy research. The first is that entrepreneurship has emerged as a bona fide focus of public policy, particularly with respect to economic growth and employment creation. The second is that neither scholars nor policy makers are presently equipped to understand the public policy role for entrepreneurship.
Validation of the Work-Life Balance Culture Scale (WLBCS).

OBJECTIVE The purpose of this paper is to describe the theoretical development and initial validation of the newly developed Work-Life Balance Culture Scale (WLBCS), an instrument for measuring an organizational culture that promotes the work-life balance of employees. METHODS In Study 1 (N=498), the scale was developed and its factorial validity tested through exploratory factor analyses. In Study 2 (N=513), confirmatory factor analysis (CFA) was performed to examine model fit and retest the dimensional structure of the instrument. To assess construct validity, a priori hypotheses were formulated and subsequently tested using correlation analyses. RESULTS Exploratory and confirmatory factor analyses revealed a one-factor model. Results of the bivariate correlation analyses may be interpreted as preliminary evidence of the scale's construct validity. CONCLUSION The five-item WLBCS is a new and efficient instrument with good overall quality. Its conciseness makes it particularly suitable for use in employee surveys to gain initial insight into a company's perceived work-life balance culture.
From leadership to customer loyalty : reconceptualizing the service-profit-chain

With consumers becoming progressively more sophisticated in their evaluations of their service consumption experiences companies are forced to focus greater attention on the nature and quality of the service provided to customers, making front-line employees of central importance for the customer experience in the service industry. An employee’s attitude and actions during the service provision can leave an impression on the customer, contributing to their level of satisfaction, loyalty and, ultimately, financial performance for the firm. This paper examines a well-known framework, the service-profit-chain, which suggests that human resource practices have the ability to effectively impact employee attitudes and behaviors in ways that can improve both service quality for customers and overall performance for the firm. However, this research contributes to the literature by proposing an expanded version of the framework, adding new predictors of customer outcomes through leadership behaviors and employee engagement. The results from two field studies suggest a number of key findings. First, the relationship between employee attitudes and performance may have been underestimated in the past due to the way the relationship has been studied. The inclusion of additional predictors better defines this relationship and equips organizations with a clearer picture in delivering high quality service, and ultimately giving firms a better chance of achieving beneficial customer outcomes. In addition, the use of a daily diary study suggests that in certain service contexts, it may be much more advantageous to study the theorized relationship in its transient form (i.e., daily, weekly, etc.) versus as stable and enduring attitudes. This research indicates that front-line service employees’ level of engagement will change from day to day, suggesting to managers that leadership behaviors must be exhibited regularly (i.e., daily) in order to ensure high level customer service is given. Implications for research and practitioners are discussed.
Hybrid Strategic Groups

The notion of strategic groups has recently emerged as a critical perspective for uncovering firms' strategic postures/recipes and competitive market structures. Firms within strategic groups generally adopt similar strategic recipes and compete more intensely than firms across strategic groups. Building on recent research, the authors develop the concept of hybrid strategic groups, which blend the strategic recipes of more than one group, in contrast to existing conceptualizations of strategic groups, where either firms tightly follow the recipes of a strategic group (i.e., core firms) or firms loosely follow the recipes of a strategic group (i.e., secondary firms). Thus, competition among firms depends not only on the strategic group but also on the overlap of that strategic group with other strategic groups. The authors devise a combinatorial optimization-based classification procedure utilizing a bilinear model that accommodates multiple variable batteries that can estimate hybrid strategic groups. The proposed methodology is illustrated by using archival data on public banks. For this illustration, the hybrid strategic group solution outperforms ordinary cluster analyses and offers critical insights into the nature of competition among firms.
Liquidity and Price Discovery of Algorithmic Trading: An Intraday Analysis of the SPI 200 Futures

We study the intra-day impact of algorithmic trading on the futures market to increase our understanding of algorithmic trading and its role in the price formation process. First, we find that algorithmic trading provides liquidity when the spread is wide and that algorithms enter the market at a series of intervals that decrease the spread. Second, we show that algorithmic trading is related to lower adverse selection and is unrelated to realised spreads. Third, we confirm that information asymmetry is highest at the beginning of the trading day, and as the price stabilises during the trading day, we find that the trade becomes the information carrier and algorithmic trading increases. Fourth, we find that algorithmic trades strategically enter the market during periods with less informed trading, while the period following exhibits higher public and private information. Our results suggest that algorithmic traders contribute to the price discovery process of financial markets.
