Purpose: This study aims to verify sellers' economic incentives for voluntarily disclosing negative information in online markets and provide practical guidelines to online sellers in terms of whether, when, and how sharing low quality to buyers increase sales. Research design, data and methodology: Our model examines the number of bidders in Internet auctions to measure potential demand and uses count data analysis following previous studies that have also analyzed the number of bidders in auctions. After checking over-dispersion and zero-inflation in our data, we have run a Poisson regression to analyze the effect of sharing negative information on sales. Results: This study presents a counterintuitive result that low-quality sellers can increase their demand by fully disclosing negative information in an online market, if appropriate risk-reducing methods are employed. Our finding thus shows that there exists economic incentive for online sellers to voluntarily disclose negative information about their products, and that the context of transactions may affect this incentive structure as the incentive varies across product categories. Conclusions: As the positive impact of disclosing negative information has rarely been studied so far, this paper contributes to the literature by providing a unique empirical analysis on the impact of sellers' honesty on sales. By verifying economic incentives of disclosing low quality with actual online sales data, this study suggests practical implications on information disclosure strategy to many online sellers dealing with negative information.

The purposes of this study were to show general trends in the aspects of psychological family environment (parental communication), peer factor, academic performance factor, depression perceived by adolescents and to examine possible changes in such trends in accordance with demographic variables and the family structure environment (parental marital status, family economic status, and parents' education level), and then to determine the effect of these variables on adolescents' depression. The subjects were 1009 middle and high school students in Seoul and Gyeonggi province. The main results were as follows: 1) Paternal communication was significantly lower in technical high school students, divorced/ separated parents, and families of lower economic status. Maternal communication was significantly lower in male students, divorced/sepa-rated parents, and families of lower economic status. Academic performance problems was significantly higher in males, technical high school students, divorced/ separated parents, families of lower economic status, and a less educated father. Peer relations was significantly lower in students of divorced / separated parents, and of families of lower economic status. Depression was significantly higher in technical high school students, divorced / separated parents, and families of lower economic status. 2) In the case of male students, paternal communication had both a direct and an indirect negative effect through peer relations on depression, while academic performance problems had both a direct and an indirect positive effect through peer relations on depression. Both peer relations and maternal communication had a positive and a negative direct effect on depression. School grade had both a direct and an indirect negative effect through paternal communication on depression. Parental marital status(divorced or separated) had both a direct and an indirect positive effect through academic performance problems on depression. Family economic status had only an indirect effect on discussed.

This study investigated the effects of perceived organizational justice on innovation resistance among instructors in sport centers and examined the mediating effects of organizational trust on these relationships. Total 274 sport instructors participated in this study. The data were analyzed by structural equation modeling, and the results of this study were as follows: First, distributive justice had a negative effect on psychological resistance, while distributive justice had no significant effect on behavioral resistance. Second, procedural justice had a negative effect on psychological resistance and behavioral resistance. Third, both distributive justice and procedural justice had a positive effect on organizational trust. Fourth, organizational trust had a negative effect on psychological resistance and behavioral resistance. Fifth, organizational trust had a partial mediating effect on the relationship between distributive justice and psychological resistance and a full mediating effect on the relationship between distributive justice and behavioral resistance. Also, organizational trust had a partial mediating effect on the relationship between procedural justice and innovation resistance.

The DC characteristics of GaAS Gunn diode are investigated as a preliminary study on the planar grade gap injector GaAs Gunn diode which is the transferred electron device with high output power and dc-rf conversion efficiency. The Gunn devices we fabricated were confirmed to have the DC characteristics of negative differential resistance(NDR). We discussed the nature of the NDR effect, including the electron intervalley transfer; the NDR effect was examined for six different cathode radii.

In the course of the investigation to the field dependent electrical conducation mechanism in polypropylene, an abnormal conduction phenomena such as voltage controlled negative resistance charateristics has been observed at the junction of two regions charateriged by schottky effect and space charge effect respectively. This abnormal characteristics was observed initially about 110MV / m of the field strength and at 25 , however, the field strength where it observed was decreased and the apparent feature of negative charateristics was less pronounced as increasing ambient temperature. Although the observations of analogous characteristics in other materials such as polyethylene, polymethylemethactylate, and polystyrene have already been reported together with plausible explanation by Toureille and others, however, it was found that the proposed concept by those authors was little use to the present observations for quantitative discussions. Accordingly we tried to adapt another conceptual discussion based on Gibbons's formulation pertaing to the saturatio trend of the field dependent drift velocity of carriers towards the thermal velocity corresponding to the ambient temperature so that the quantitative explanatio on the observed facts has been succeeded to some estent of reasonable acceptance.

The negative curvature effect on the breakdown voltage of p-n junction, which may realize 1-D breakdown voltage due to the lower peak electric field at the junction, is proposed and verified by the fabrication of lateral diode on Silicon-on-Insulator (SOI) together with MEDICI simulation. The experimental and simulation results show good agreements with the theoretical expectation. The proposed method is effectively applicable to the lateral, especially on SOI, power devices.

The purpose of this study was to examine sex and grade differences in children's body shape, body image perception and diet behavior and to identify the effect of children's body shape and body image perception on their eating behavior. Data were collected from 345 3rd and 6th graders by questionnaire and analyzed by t-test, ANOVA, and Scheff. Girls' body image perception was more negative than boys' and 6th graders' was more negative than 3rd graders'. Self-perceived obese children had more negative body image and had attempted to go on a diet more often than children who thought themselves normal or thin. The more children perceived their body image negatively, the more they attempted to go on a diet and perceived food and eating negatively.
