The influence of EWOM characteristics on online repurchase intention: Mediating roles of trust and perceived usefulness

Purpose With the expansion of internet as a tool for exchanging information, companies include in their websites a virtual space to share information among users. The purpose of this paper is to explore the characteristics of consumers’ reviews (electronic word-of-mouth quantity, credibility and quality) as antecedents of customers’ online repurchase intentions. Specially, it proposes a model where trust on an online seller and perceived usefulness of a website mediate the influence of electronic word-of-mouth (EWOM) characteristics on repurchase intentions. Design/methodology/approach Structural equation modeling was employed on a sample of 252 online customers. An online questionnaire was aimed at internet users who had previously made an online purchase and read online reviews received from the vendor’s website. Findings Results show that only EWOM quality has a positive direct effect on consumers’ repurchase intention while quantity has a negative influence. Perceived usefulness mediates the influence of all EWOM characteristics on online repurchase intention. EWOM credibility and quality also indirectly influence repurchase intentions through trust on the online vendor. Practical implications This paper outlines ways to improve managerial implications by developing mobile applications or websites where the reviews have an appropriate volume and quality of information. Moreover, it suggests general advice to present online reviews in a useful manner to users who visit these websites. Originality/value This study is one of the first to propose an integrative model that studies in depth the three main EWOM characteristics and customer responses for understanding their repurchase behavior.
Characterization of two types of human papillomaviruses in lesions of epidermodysplasia verruciformis.

Human papillomaviruses (HPVs) found in lesions of 11 patients suffering from epidermodysplasia verruciformis were compared to HPV type 1 (HPV-1) and HPV type 2 (HPV-2) previously characterized in plantar and common warts, respectively. Complementary RNAs (cRNAs) to HPV-1, HPV-2, and viruses obtained from two patients with epidermodysplasia verruciformis (J.D. HPV and J.K. HPV) were used in cRNA.DNA filter hybridization experiments. No sequence homology was detected between HPV-1 or HPV-2 DNAs and DNAs obtained from the 11 epidermodysplasia verruciformis HPV isolates. Furthermore, with J.D. and J.K. HPV cRNAs, epidermodysplasia verruciformis HPV DNAs fell into two groups showing little, if any, sequence homology. A lower extent of annealing was observed for the DNAs of some isolates showing a genetic heterogeneity within each of the two groups. Almost no antigenic crossreaction was detected by immunodiffusion and indirect immunofluorescence tests, either between epidermodysplasia verruciformis HPVs and HPV-1 or HPV-2 or between J.D. and J.K. HPVs. Viruses belonging to the same group have common antigenic properties, but antigenic differences were observed when two of the viruses sharing only partial DNA sequence homology were compared. Viruses related to J.D. HPV were preferentially associated with flat wart-like lesions of epidermodysplasia verruciformis and were further found in the lesions of five patients bearing multiple flat warts. Viruses related to J.K. HPV were found in morphologically distinct lesions (red spots) present in some patients with epidermodysplasia verruciformis. Thus, we propose to distinguish two other types of HPVs designated provisionally as HPV type 3 (HPV-3) and HPV type 4 (HPV-4), with J.D. and J.K. HPVs as prototypes, respectively. Malignant conversion of some epidermodysplasia verruciformis lesions is more frequently associated with HPV-4 than with HPV-3 infection.

Does Network Care Prolong Work Absences?

We used data on 120,000 workers with occupational injuries occurring in California, Connecticut, and Texas to analyze the effects of healthcare networks on postinjury durations of work absence. Controlling for selection and unobserved heterogeneity, work absences are shorter, all else equal, for network cases than for non-network cases. The shorter durations could reduce lost productivity by more than $3.8 million (a 9% reduction in work loss days for non-network cases) if network care were extended to the non-network cases in our sample.
Molecular cloning and expression of the mouse N-acetylneuraminic acid 9-phosphate synthase which does not have deaminoneuraminic acid (KDN) 9-phosphate synthase activity.

A cDNA of the mouse homologue of Escherichia coli N-acetylneuraminic acid (Neu5Ac) synthase (neuB gene product) was cloned by the PCR-based method. The mouse homologue consists of 359 amino acids, and the cDNA sequence displays 33% identity to that of the E. coli Neu5Ac synthase. The recombinant mouse homologue which is transiently expressed in HeLa cells does not exhibit the Neu5Ac synthase activity, which catalyzes condensation of phosphoenolpyruvate (PEP) and N-acetylmannosamine (ManNAc) to synthesize Neu5Ac, but the Neu5Ac 9-phosphate (Neu5Ac-9-P) synthase activity, which catalyzes condensation of PEP and ManNAc 6-phosphate (ManNAc-6-P) to synthesize Neu5Ac-9-P. Thus, the mouse homologue of E. coli Neu5Ac synthase is the Neu5Ac-9-P synthase. The Neu5Ac-9-P synthase is a cytosolic enzyme and ubiquitously distributed in mouse various tissues. Notably, the Neu5Ac-9-P synthase can not catalyze the synthesis of deaminoneuraminic acid (KDN) or KDN-9-P from PEP and Man or ManNAc-6-P, thus suggesting that the enzyme is not involved in the synthesis of KDN. This is consistent with the previous observation that only a very low activity to synthesize KDN is found in mouse B16 cells [Angata, T. , et al. (1999) Biochem. Biophys. Res. Commun. 261, 326-331].
IMPACT OF PROPYL THIOURACIL ON TESTES FUNCTIONS AND SEMEN CHARACTERISTICS OF NEW ZEALAND WHITE RABBITS

This study was carried out at Intensive Rabbit Production Unit, belonging to Agriculture Studies and Consultation Center, Faculty of Agriculture, Ain Shams University. The study was designed to investigate the effect of 6-n-propyl-2-thiouracil (PTU) injection on testicular development and semen characteristics of male rabbits under intensive production. Sixty three New Zealand White (NZW) male rabbits were used. Three male rabbits (zero time) were slaughtered, the rest was divided randomly into two groups, the first group (PTU) 30 animals were subcutaneously injected daily with PTU 20 μg/g live body weight from the 1 st day until the weaning (28 day of age) and the second group (C) of 30 animals served as control and injected daily with the. The study showed that the treatment with PTU reduced (P≥ 0.001) live body weight during pre and post weaning periods. Testis measurements increased (P≥ 0.0001) in PTU treated group compared with control group at 30, 60, 90, 120 and 150 days of age. Seminiferous tubules and Leydig cells indices increased (P ≥ 0.001) in PTU treated group (71.42 % and 18.97 %) compared with control group, respectively. The ejaculate volume of PTU treated rabbits was larger (P ≥ 0.001) compared with control rabbits. The average sperm concentration /ml and advanced motility were 485.57 X 10 6 vs. 312.07 X 10 6 and 87.21 % vs. 78.23 % for PTU and control groups, respectively. The percentages of abnormal and dead spermatozoa were 16.07 % vs. 20.95 % and 5.03 % vs. 12.33 % for treated and control groups, respectively. In conclusion, the 6-n-propyl-2-thiouracil can be used to increase testis size, ejaculate volume and sperm concentration. Despite these promising results, the use of PTU to produce male rabbits with larger testes and a better quality of semen needs further investigations in order to reduce the number of males breeding for artificial insemination purposes.
Optimization and the Robustness of BOX A 1 R PCR for DNA Fingerprinting Using Trout Lake E . coli Isolates

The rep-PCR DNA fingerprint technique using BOX A1R primer was investigated. DNA fingerprints were generated from Escherichia coli strains isolated from human, duck, goose, gull, and heron sources. Optimization tools (use of restriction enzymes, BSA, DMSO, and storage buffer) were used in an attempt to generate clear, well-defined DNA fingerprints from the Escherichia coli isolates. Initial studies revealed that although there were distinct fingerprint patterns emerging from the use of BOX A1R primer, the bands were faint and difficult to resolve. The use of optimization tools did not significantly improve the quality of the bands or the reproducibility of the method except for BSA. BSA seemed to improve the reproducibility of the method. This failure in optimizing the rep-PCR DNA fingerprinting technique may be due to the formation of primer dimers. Further research is required into this problem.
Molar–Incisor Hypomineralisation

At the recent congress of the European Academy of Paediatric Dentistry, four presentations were given on permanent first molars with enamel developmental defects [Beentjes et al., 2000; Jälevik et al., 2000; Leppäniemi et al., 2000; Weerheijm et al., 2000]. The presenters had named the defects ‘hypomineralised permanent first molars’, ‘idiopathic enamel hypomineralisation in the permanent first molars’, ‘nonfluoride hypomineralisation in permanent first molars’ and ‘cheese molars’. Although the denominations differ, the clinical description of the phenomenon was similar in each paper. The defects ranged from white-yellow or yellow-brown demarcated opacities to severely hypomineralised broken enamel (fig. 1, 2). The phenomenon was well known to the clinicians at the congress and it has also been described using various names in recent studies [Koch et al. 1987; van Amerongen and Kreulen, 1995; Alaluusua et al., 1996, 1999; Hölttä et al., 2001]. Also not long ago, such molars were reported by Jan and Vrbic [2000] and Lepäniemi et al. [2001]. The aim of the present communication is to describe the phenomenon briefly and find a common name for it.
Nutritional Compositions and Antiproliferative Activities of Different Solvent Fractions from Ethanol Extract of Cyphomandra betacea (Tamarillo) Fruit.

Background This study aims to examine various solvent extracts of Cyphomandra betacea (tamarillo) also known as the tree tomato, for their bioactive constituents and antioxidant activity. The study also aims to examine its effect on cancer cell death using two types of cancer cell lines (liver and breast cancer cell). Methods The first part of the study evaluates the nutritional composition of tamarillo. Then, phytochemical profiling using GC-MS analysis in ethanolic tamarillo extract was conducted. Different fractions of n-butanol, ethyl acetate and aqueous fractions were obtained from the ethanolic extract of tamarillo. Then, the fractions were subjected to the quantification of total phenol (TPC) and flavonoid contents (TFC), free radical scavenging activity (SA) and also antioxidant activity (AOX) assayed by beta-carotene bleaching (BCB) assay. Finally, the capability of the ethanolic extract of tamarillo and different fractions were evaluated for their anticancer properties. Results Findings from this study revealed that the nutritional composition (ash, protein, carbohydrate and total dietary fiber), and mineral levels (calcium, magnesium, potassium and iron) of tamarillo were moderate. The crude ethanol extract of tamarillo contained the highest phenolic and total flavonoid content. FT-IR analysis revealed the presence of alkanes, carboxylic acid, phenol, alkanes, carboxylic acids, aromatics and nitro compounds. Twelve bioactive constituents in tamarillo have been identified through GC-MS analysis. Cytotoxic activity suggests the potential of ethanolic extracts of tamarillo having a chemopreventive effect on breast and liver cancer cells. Conclusion This study reveals that tamarillo has substantial antioxidant activity as well as anticancer properties.
Multiscale investigation of stress-corrosion crack propagation mechanisms in oxide glasses

Abstract Fracture propagation involves the coupling of many length scales ranging from the sample loading geometry to the molecular level. In brittle materials, the length scales of the damage process zone are reduced to a submicrometric scale and the coupling with the macroscopic scale is expected to be the domain of linear elastic fracture mechanics. However, although 2D elastic analyses are generally adequate to describe the sample deformation at macroscopic scales, local investigations of failure mechanisms at the sample-free surface require the use of 3D mechanical tools due to the crack front local curvature and to the corner point singularities at the intersection between the crack front and the external surfaces of the sample. We present here a thorough multiscale investigation of the slow crack growth of a sharp crack in oxide glasses in the stress-corrosion regime, combining experimental and numerical analyses of the displacement fields from the millimeter scale to the nanoscale range. The principal aim of the study is identifying the length and time scales of the mechanisms of damage and interaction between water and glass, which have been the subject of an extensive debate in the last decades.
Is Integration Enough for Fast Product Development? An Empirical Investigation of the Contextual Effects of Product Vision*

Research into development time performance has suggested that integration—both internal, adopting cross-functional organizational structures for development, and external, involving customers and suppliers in the process—can be a powerful driver when it comes to compressing cycle times and enhancing development punctuality. Some recent studies have also highlighted the compelling role of product vision to obtain high performances with product development. What these studies seem to suggest is that product vision guarantees the right goals and clarity of direction that integration mechanisms need to quickly develop new products and to stay on the development schedule. However, past studies have rarely considered or measured product vision as a construct and explicitly tested whether or not product vision acts as a contingent factor in determining the relationships between the aforementioned organizational drivers and development time. This research study maintains that product vision is crucial to pushing organizational drivers toward increased development efficiency. To find theoretical support for this position and to define a reference framework for the study, previous literature was analyzed. In the framework, both internal and external development integration are assumed to be positively related to time performance; however, these relationships are moderated by product vision. The model was then tested empirically on an international sample of 157 firms to verify and to obtain empirical support for the hypothesized relationships. The results confirm the importance of external integration in achieving better time performance. However, the influence of this driver on cycle time can also be increased by the presence of a very well-defined product vision. The relationship between internal integration and time performance is more complex. Though it seems to slow down the process as a single factor, its interaction effect with product vision is in fact positive. These results have several managerial implications. First, externally integrated development can greatly improve time performance; however, the best results in terms of acceleration can be obtained when there is a well-defined product vision. Furthermore, product vision is essential in the case of internal integration: A cross-functional process alone would not be enough for development acceleration in the absence of product vision. Hence, managers interested in obtaining high time performances should accompany the adoption of integration mechanisms with increased attention to sharing clear objectives and directions with all those—both inside the firm (i.e., team members and functional representatives) and outside the firm (i.e., customers and suppliers)—involved in development and as well as throughout the firm.

A study of the effects of biaxial strain on the performance of low-threshold 1.3- mu m In/sub x/Ga/sub 1-x/As/sub y/P/sub 1-y//InP quantum-well lasers is presented. Lasers with lattice-matched, compressive-strained, and tensile-strained quantum-wells were fabricated to compare the effect of strain on various device parameters. Threshold current densities as low as 187 A/cm/sup 2/ for a two-quantum-well device with 0.85% compressive strain were obtained. <<ETX>>
Genetic variation in MYLK and lung injury in children and adults with community-acquired pneumonia*

Objective: To investigate whether selected single nucleotide polymorphisms in the myosin light chain kinase gene are associated with more severe lung injury in children and adults with community-acquired pneumonia. Previous studies have demonstrated an association between single nucleotide polymorphisms in the myosin light chain kinase gene and increased severity of acute lung injury in adults. Design: Prospective, case-control genetic association study. Setting: Three tertiary children's hospitals and one adult healthcare system. Patients: A total of 800 pediatric patients and 393 adult patients. Interventions: None. Measurements and Main Results: Genetic variation in the myosin light chain kinase gene was examined. The pediatric cohort was predominantly composed of African American (n = 443) and Caucasian (n = 253) children. A total of 393 patients made up the adult cohort. Within the pediatric cohort, single nucleotide polymorphisms rs16834493, rs820463, and rs9840993 were genotyped in the African American patients, whereas single nucleotide polymorphisms rs960224, rs33264, rs11718105, and rs9289225 were genotyped in the Caucasian patients. One single nucleotide polymorphism (rs820336) was genotyped in both groups. Genotyping in the adult cohort included rs820336, rs860224, rs33264, and rs11718105. Genotyping was performed using the Taqman Assay. Data were analyzed separately for African Americans and Caucasians and for children and adults. No associations were observed between the myosin light chain kinase gene single nucleotide polymorphisms genotyped in children with community-acquired pneumonia and increased severity of lung injury. Similarly, no associations were observed between myosin light chain kinase gene single nucleotide polymorphisms genotyped in adults with community-acquired pneumonia and increased severity of lung injury. Conclusions: No association between the selected single nucleotide polymorphisms in the myosin light chain kinase gene and either the need for positive-pressure ventilation or the development of acute lung injury/acute respiratory distress syndrome was observed in children with community-acquired pneumonia. This suggests that variation in this gene may play less of a role in lung injury in children or adults with community-acquired pneumonia than in adults with sepsis or trauma.
Clinical patterns and outcomes of ischaemic colitis: Results of the Working Group for the Study of Ischaemic Colitis in Spain (CIE study)

Abstract Background. There is a lack of prospective studies evaluating the natural history of colonic ischaemia (CI). We performed such a study to evaluate the clinical presentation, outcome, and mortality as well as clinical variables associated with poor prognosis. Methods. An open, prospective, and multicentre study was conducted in 24 Spanish hospitals serving a population of 3.5 million people. The study included only patients who met criteria for definitive or probable CI. A website (www.colitisisquemica.org) provided logistical support. Results. A total of 364 patients met criteria for inclusion. CI was suspected clinically in only 24.2% of cases. The distribution of clinical patterns was as follows: reversible colopathy (26.1%), transient colitis (43.7%), gangrenous colitis (9.9%), fulminant pancolitis (2.5%), and chronic segmental colitis (17.9%). A total of 47 patients (12.9%) had an unfavorable outcome as defined by mortality and/or the need for surgery. Multivariate analysis identified the following signs as independent risk factors for an unfavorable outcome: abdominal pain without rectal bleeding [odds ratio (OR) 3.9; 95% confidence interval (CI) = 1.6–9.3], non-bloody diarrhoea (OR 10; 95% CI = 3.7–27.4), and peritoneal signs (OR 7.3; 95% CI = 2.7–19.6). Unfavorable outcomes also were more frequent in isolated right colon ischaemia (IRCI) compared with non-IRCI (40.9 vs. 10.3%, respectively; p < 0.0001). The overall mortality rate was 7.7%. Conclusions. The clinical presentation of CI is very heterogeneous, perhaps explaining why clinical suspicion of this disease is so low. The presence of IRCI, and occurrence of peritoneal signs or onset of CI as severe abdominal pain without bleeding, should alert the physician to a potentially unfavorable course.
