Sellers in Online Auction Markets: Introducing a Feedback-Based Classification

Increasing significance of the online consumer-to-consumer (C-2-C) auction market has amplified the need for buyers and sellers to engage in transactions with anonymous counterparts. The sequence of paying first and then taking delivery, introduces a great amount of risk for potential buyers. In order to mitigate this risk, online auction markets (OAMs) are employing an assortment of governance mechanisms, of which reputation scoring and reporting systems are the most popular. Researchers have found substantial evidence from theoretical models as well as empirical studies that higher the reputation rating of a seller, higher the bid prices he/she receives. However, a review of the current literature suggests a conspicuous absence of any standard classification of sellers in OAMs. Lack of such a classification hinders systematic research and theory development. Therefore, a comprehensive classification of sellers, based on feedbacks, is proposed to advance our understanding of online C-2-C auction market and to provide a basis for further research. In addition, the proposed classification is hierarchical rather than monothetic in nature and hence, gives greater systemic power to the classification. Toward demonstrating the classification’s systemic power, we present a propositional inventory developed from the classification. We also discuss how the proposed classification accommodates current research and furthers theory building in this research area.
Effects of Serenoa repens, selenium and lycopene (Profluss®) on chronic inflammation associated with benign prostatic hyperplasia: results of "FLOG" (Flogosis and Profluss in Prostatic and Genital Disease), a multicentre Italian study.

OBJECTIVE To evaluate the efficacy of Profluss® on prostatic chronic inflammation (PCI). MATERIALS AND METHODS We prospectively enrolled 168 subjects affected by LUTS due to bladder outlet obstruction submitted to 12 cores prostatic biopsy for suspected prostate cancer + 2 cores collected for PCI valuation. First group consisted of 108 subjects, with histological diagnosis of PCI associated with BPH and high grade PIN and/or ASAP, randomly assigned to 1:1 ratio to daily Profluss® (group I) for 6 months or to control group (group Ic). Second group consisted of 60 subjects, with histological diagnosis of BPH, randomly assigned to 1:1 ratio to daily Profluss® + a-blockers treatment (group II) for 3 months or to control group (group IIc). After 6 months first group underwent 24 cores prostatic re-biopsy + 2 cores for PCI while after 3 months second group underwent two-cores prostatic for PCI. Specimens were evaluated for changes in inflammation parameters and for density of T-cells (CD3, CD8), B-cells (CD20) and macrophages (CD68). RESULTS At follow-up there were statistical significant reductions of extension and grading of flogosis, mean values of CD20, CD3, CD68 and mean PSA value in group I compared to Ic, while extension and grading of flogosis in group II were inferior to IIc but not statistical significant. A statistically significant reduction in the density of CD20, CD3, CD68, CD8 was demonstrated in group II in respect to control IIc. CONCLUSIONS Serenoa repens+Selenium+Lycopene may have an anti-inflammatory activity that could be of interest in the treatment of PCI in BPH and/or PIN/ASAP patients.
Measuring Sexual Victimization

Rennison and Addington use National Crime Victimization Survey (NCVS) data to document the fact that college women experience violent victimization at a lower rate than women of the same age who do not attend college, which refutes the idea that women in college are at increased risk of being victimized. The measurement of victimization, especially sexual victimization, is, however, a topic that has be the source of much debate. Bureau of Justice Statistics is currently exploring what are the best methods for measuring sexual victimization within the NCVS, and recent methodological research, which is summarized in this article, could inform this process. Although consensus has seemingly been forming around come methods, such as using self-administered survey instruments and behaviorally specific questions when trying to measure sexual victimization, the jury is still out on some other design fronts. What is not clear is whether we need the jury to come in, so to speak. Some methodological variation might be acceptable, especially if the various methods being considered are producing similar results.
Persistence of a repressed Epstein-Barr virus genome in Burkitt lymphoma cells made resistant to 5-bromodeoxyuridine.

The P3HR-1 line of human lymphoblastoid cells that is Epstein-Barr virus positive was made resistant to 5-bromodeoxyuridine. Epstein-Barr virus-associated antigens, but not virus particles, were produced in P3HR-1(BU) cells maintained on 5-bromodeoxyuridine. However, virus particles did appear within 4 days after removal of the drug. Thymidine kinase activity was limited to P3HR-1(BU) cells producing viral antigen, whereas all control P3HR-1 cells showed thymidine kinase activity regardless of viral antigen synthesis. Cellular DNA in most P3HR-1(BU) cells was made via pathways that did not involve thymidine kinase. In cells having a pathway that involved thymidine kinase, a second DNA of density 1.71 g/cm(3), corresponding to Epstein-Barr virus, was detected.IT WAS CONCLUDED THAT: (a) a repressed Epstein-Barr virus genome persists in P3HR-1(BU) cells that do not contain thymidine kinase, with activation of the viral genome being accompanied by productive infection and the appearance of enzyme, and (b) thymidine kinase activity in P3HR-1(BU) cells could be used as a marker for viral genome expression.
Age and Gender Differences and Predictors of Victimization of the Older Homeless

ABSTRACT Using data from the National Survey of Homeless Assistance Providers and Clients (NSHAPC) and an application of Felson's Routine Activities Theory, this paper examines gender and age differences in victimization experiences of a sample of more than 4,200 homeless and near-homeless people, mostly adults. Results suggest that there are no differences in victimization experience by homelessness status and that the negative relationship between age and victimization rates found in the general population is also found in the homeless population. However, the relationship is relatively weak and erratic, suggesting that homeless older adults who are at least 50 years old are at increased risk of becoming victims, a finding consistent with Routine Activities Theory. In addition, similar to research with other populations, younger homeless males are statistically more likely to report being victims of theft and physical assault while females of all ages are more likely to report being victims of sexual assault. However, for older homeless adults, the gender difference in likelihood of victimization disappears. Perhaps because older homeless women are labeled as easy targets, they were equally as likely as men to be victims of physical assault and theft in old age. This is also consistent with Routine Activities Theory.
An agent‐based simulation model of human‐robot team performance in military environments

Prior to deploying human‐robot teams on military missions, system designers need to understand how design decisions affect team performance. This paper describes a multiagent simulation model that captures both team coordination and human‐robot interaction. The purpose of the model is to evaluate proposed team designs in uncertain Military Operations in Urban Terrain (MOUT) scenarios and determine which design factors are most critical to team performance. The simulation model is intended to be a tool in the systems engineering iterations of proposing designs, testing them, and then evaluating them during the conceptual design phase. To illustrate the model's usefulness for this purpose, a fractional factorial design of experiments is conducted to evaluate team design factors and the two‐factor interaction between controllable factors and noise factors that described the environment and robot reliability. The experimental results suggest that (1) larger teams have more robust performance over the noise factors, (2) robot reliability is critical to the formation of human‐robot teams, and (3) high centralization of decision‐making authority created communication bottlenecks at the commander in large teams. This work contributes to the agent‐based modeling of teams, and to understanding how the U.S. Army can attain its goal of greater utilization of robots in future military operations. ©2012 Wiley Periodicals, Inc.

An Empirical Study of Small- and Medium-Sized Firms in Taiwan: Entrepreneurship, Core Competency and Market Performance

The average life of smalland medium-sized enterprises (SMEs) in Taiwan has gradually increased from 13 to 20 years, and more than 97% of companies are SMEs. SMEs have been the main structure in the Taiwanese economy and, for this reason, entrepreneurship is very important. Since the 1990s, the trend of globalization has prompted rapid changes and increased competition in the industrial environment. One of the major concerns of SME owners is how to combine entrepreneurship with core competency to improve business performance. This study aims to explore the relationship among entrepreneurship, core competency and market performance. For this purpose, 1,207 questionnaires were mailed to SME owners in Taiwan, of which 155 were returned. It was found that the owners of SMEs place a high emphasis on entrepreneurship to improve profitability and revenue growth, while enhancing their core competences to improve market performance.
Using the M-score Model in Detecting Earnings Management: Evidence from Non-Financial Vietnamese Listed Companies

Abstract Earnings management is considered to be one of the most important issues related to financial statements, which has been well-documented in accounting theory and practice for a long time. Earnings management has become a critical topic in accounting, but few researchers have addressed this issue in the Vietnamese context. This paper examines earnings management detection among Vietnamese companies listed on the Hochiminh Stock Exchange (HOSE) by using the Beneish M-score model for a sample of 229 non-financial Vietnamese companies listed on the HOSE during 2013-2014. The results showed that 48.4% non-financial Vietnamese companies listed on the HOSE were involved in earnings management and the sample observations fit the Beneish M-score model. In conclusion, this study suggests that the M-score model is one of the useful techniques in detecting earnings manipulation behaviors of the companies and it could be applied for an improvement in financial reporting quality and a better protection for investors.

Response to “Characterization of Unbound Phenytoin Concentrations in Neurointensive Care Unit Patients Using a Revised Winter-Tozer Equation” by Sean P. Kane, Adam P. Bress, and Eljim P. Tesoro

TO THE EDITOR: We read with great interest the study by Kane et al evaluating multiple equations to correct total phenytoin levels in neurointensive care patients. This study is to be commended for its large sample size and focus on critically ill patients, who have multiple reasons for altered phenytoin concentrations. They found the traditional Winter-Tozer (WT) equation significantly underpredicted patients’ actual free phenytoin concentrations and concluded it is not appropriate to use in this population. They found greater correlation between predicted and actual free phenytoin concentrations with a modified WT equation and an equation developed through multivariate analysis. Previous studies evaluating the WT equation’s predictive ability have shown mixed results. We conducted an analysis of internal data in our neurointensive patient population to see how patient’s phenytoin binding changes throughout their stay. Our cohort included 100 patients and 556 paired total and free phenytoin concentrations. The average free fraction of phenytoin in our group was 18.8% and the average albumin was 2.7 g/dL. Following the results from Kane et al, we applied the 3 equations used (WT, multivariate liner regression model, and modified WT coefficient) to our data in an attempt to validate their results. We applied these equations to each patient’s first phenytoin concentrations and albumin level as Kane et al did (group 1, n = 92), then to the patient’s phenytoin concentrations and albumin levels throughout their entire intensive care unit stay (group 2, n = 312). Surprisingly, we found the traditional WT equation had the greatest correlation when compared with the other 2 equations, and overall, all 3 equations correlated poorly with actual free phenytoin concentrations (see Table 1). These markedly different results may be because of differences in study design and baseline demographics. Our data are from the patients’ entire stay in the neurointensive care unit (each patient had multiple phenytoin concentrations) versus within the first 24 hours of admission as Kane et al used. Also, our patients had a mean albumin of 2.7 g/ dL versus a mean albumin of 3.3 g/dL in Kane et al’s group. Overall, we agree with Kane et al’s idea of developing new predictive equations accounting for other variables in addition to albumin. Both our results have shown that the WT equation is not reliable in neurointensive patients. Future studies evaluating predictive phenytoin equations should include a variety of variables in their analysis.
A pilot study on the effects of prednisone withdrawal on serum hepatitis B virus DNA and HBeAg in chronic active hepatitis B

We investigated the efficacy of a short course of prednisone therapy in 20 patients with histologic evidence of chronic active hepatitis B. Sixteen of 20 prednisone‐treated patients who were initially serum hepatitis B virus DNA‐positive had a transient elevation of their serum ALT activity on withdrawal of prednisone. Subsequently, 14 of these 16 patients (87.5%) became persistently negative for serum hepatitis B virus DNA, and 10 also lost their HBeAg. In addition, there was a significant fall in serum ALT levels and HBsAg titers up to 12 months of follow‐up in the prednisone‐treated group. Five of 20 (25%) prednisone‐treated patients experienced a transient episode of hepatic decompensation coinciding with the peak of enzyme elevation.
A genetic screen in rodent malaria parasites identifies five new apicoplast putative membrane transporters, one of which is essential in human malaria parasites

The malaria‐causing parasite, Plasmodium, contains a unique non‐photosynthetic plastid known as the apicoplast. The apicoplast is an essential organelle bound by four membranes. Although membrane transporters are attractive drug targets, only two transporters have been characterised in the malaria parasite apicoplast membranes. We selected 27 candidate apicoplast membrane proteins, 20 of which are annotated as putative membrane transporters, and performed a genetic screen in Plasmodium berghei to determine blood stage essentiality and subcellular localisation. Eight apparently essential blood stage genes were identified, three of which were apicoplast‐localised: PbANKA_0614600 (DMT2), PbANKA_0401200 (ABCB4), and PbANKA_0505500. Nineteen candidates could be deleted at the blood stage, four of which were apicoplast‐localised. Interestingly, three apicoplast‐localised candidates lack a canonical apicoplast targeting signal but do contain conserved N‐terminal tyrosines with likely roles in targeting. An inducible knockdown of an essential apicoplast putative membrane transporter, PfDMT2, was only viable when supplemented with isopentenyl diphosphate. Knockdown of PfDMT2 resulted in loss of the apicoplast, identifying PfDMT2 as a crucial apicoplast putative membrane transporter and a candidate for therapeutic intervention.
Hypoxia in the Term Newborn: Part Three—Sepsis and Hypotension, Neurologic, Metabolic and Hematologic Disorders

Causes of hypoxia and cyanosis in the term newborn can be found within all physiologic systems and take the form of hundreds of specific diagnoses. In the first and second parts of this series, a wide range of cardiac and pulmonary causes for newborn hypoxia and cyanosis have been examined. Because they are familiar, cardiac and pulmonary diagnoses often represent our reactionary opinions—the options that we first entertain even before a proper systematic approach to the infant has been taken. In this final of a three part series, neurologic, hematologic and metabolic disorders are explored as a cause for abnormal oxygenation, as well as sepsis and hypotension. It is within these final categories that we find many of the obscure possibilities for neonatal hypoxia—the diagnoses that often require rigorous testing, or more sophisticated laboratory interpretation. Without consideration of these elusive entities, however, appropriate treatment and referral will be unnecessarily delayed.
EXPLORATION OF HUMAN BEHAVIOR OF WATER-SAVING UNDER CLIMATE CHANGE USING EXPANDED THEORY OF PLANNED BEHAVIOR MODEL

In response to the water shortage issue caused by climate change, an extending planned behavior model of environmental concern is applied to explain the household behavior relatedto water conservation in southern Taiwan. Based on the data from the 1678 valid samples using random sampling, an extending planned behavior model to which the variable of environmental concern is added besides the original variables in the theory of planned behavior (TPB) model. It was also verified to properly explain the household behavior related to water conservation for climate change mitigation. Furthermore, the exploratory factor analysis was successfully extracted into the three factors in environmental concern and the four factors in water conservation behavior. The results indicate that the extended TPB model including environmental concern can increase the explanatory power of the original one. In addition to the attitudes, perceived behavioral control and subjective norm, people's environmental concerns may reduce the impact on global warming and climate change. As a result, people's intentions to engage in water savings and carbon reduction behavio rs can be expected to mitigate climate change problems.

Emergency Department Revisits for Pediatric Acute Asthma Exacerbations: Association of Factors Identified in an Emergency Department Asthma Tracking System

Objective: To identify clinical variables associated with a greater likelihood of emergency department (ED) revisit for acute asthma within 7 days after an initial ED visit for acute asthma exacerbation. Methods: Cross-sectional study of subjects from a prospectively enrolled cohort of children aged 0 to 18 years with physician-diagnosed asthma in the ED Allies Tracking System. Demographics and data on quality of life, health care utilization, environmental factors, chronic asthma severity, and ED management were collected. Emergency department revisits for acute asthma within 7 days of a prior visit resulting in discharge were compared with those without a revisit, using &khgr;2 and t tests and logistic regression. Results: Four thousand two hundred twenty-eight ED asthma visits were enrolled; 3276 visits resulted in discharge. Persistent asthma was identified in 66% of visits. Emergency department revisits within 7 days of a prior visit occurred following 133 (4.1%) visits. There were no significant differences in environmental factors or ED management between visits with and without an ED revisit. In univariate analysis factors associated with a greater revisit likelihood included age younger than 2 years, black race or Hispanic ethnicity, persistent asthma, public insurance, lower quality of life, and greater health care utilization in the prior 12 months. Variables independently significant (P < 0.05) in logistic regression were chronic asthma severity classified as persistent, age younger than 2 years, and lower asthma quality of life. Conclusions: Although our design precludes drawing causal inference, our results suggest that children younger than 2 years or with persistent asthma or lower asthma quality-of-life scores are at greater risk for ED revisits after acute ED asthma care.
Vodi li namjera korištenja tehnologijom njezinoj stvarnoj upotrebi? Istraživanje sustava e-učenja među studentima u Maleziji

This paper intends to investigate the long debated notion of whether intention really leads to actual behavior in the e-learning environment. A model based on the Technology Acceptance Model (TAM) was tested using data gathered through a structured questionnaire with participation of undergraduate students from a number of universities in Malaysia. Using the variance based structural equation modeling analysis of Partial Least Square (PLS) the model obtained a GoF value of 0.602 which exceeded the 0.36 cut-off value for large effect sizes of R2, thus providing adequate support to validate the PLS model globally. All the hypotheses developed were corroborated with strong support for the Intention related to the Actual use, thus confirming the validity of the TAM in e-learning and within a context of a developing country. Implications for developers and administrators are further elaborated.
Evidence for the braking of flow bursts as they propagate toward the Earth

In this article we use energy conversion arguments to investigate the possible braking of flow bursts as they propagate toward the Earth. By using E·J data (E and J are the electric field and the current density) observed by Cluster in the magnetotail plasma sheet, we find indications of a plasma deceleration in the region −20 RE < X < − 15 RE. Our results suggest a braking mechanism where compressed magnetic flux tubes in so‐called dipolarization fronts (DFs) can decelerate incoming flow bursts. Our results also show that energy conversion arguments can be used for studying flow braking and that the position of the flow velocity peak with respect to the DF can be used as a single‐spacecraft proxy when determining energy conversion properties. Such a single‐spacecraft proxy is invaluable whenever multispacecraft data are not available. In a superposed epoch study, we find that a flow burst with the velocity peak behind the DF is likely to decelerate and transfer energy from the particles to the fields. For flow bursts with the peak flow at or ahead of the DF we see no indications of braking, but instead we find an energy transfer from the fields to the particles. From our results we obtain an estimate of the magnitude of the deceleration of the flow bursts, and we find that it is consistent with previous investigations.
The Effects of Hands Free Communication Devices on Clinical Communication: Balancing Communication Access Needs with User Control

Hands Free Communication Device (HFCD) systems are a relatively new information and communication technology. HFCD systems enable clinicians to directly contact and communicate with one another using wearable, voice-controlled badges that are VoIP-based (voice-over IP) and are linked to one another over a wireless local area network (WLAN). This qualitative study utilized a grounded theory, multiple perspectives approach to understand how the use of HFCDs affected communication in the hospitals that implemented them. The study generated five themes revolving around HFCDs impact on communication. This paper specifically focuses on two of those themes: Communication Access and Control.
