Online auctions are a popular means for exchanging items over the Internet. However, are many inherent security and fairness concerns. Participants can behave in an undesirable and fraudulent manner in an attempt to gain an advantage at the expense of rivals. For example, a bidder might seek to suppress the price by bid sniping, or the seller could introduce fake bids to inflate the price. In a...

Illusory correlation research has identified two factors that lead subjects to overestimate the relationship between particular categories of people and particular types of behavior: associative connections and shared infrequency. Three studies examined the nature of illusory correlation effects when both of these factors operated simultaneously. The results were consistent with previous shared...

The purpose of this study is to identify factors affecting the development of entrepreneurship in theagricultural advisory services companies. The main instrument to collect the data was questionnaire and itsvalidity of questionnaire is confirmed by experts and its reliability is measured through Cronbach’s alpha(75%). The data were analyzed by SPSS software version 16. The finding showed that ...

obesity with an increasing prevalence rate worldwide is correlated with multiple comorbidities. unfortunately, the currently available therapies such as the pharmacotherapy, bariatric surgery or gene-transfer technology are associated with a number of disadvantages including undesirable side effects, poor compliance or transient effectiveness. therefore, modifications of the lifestyle factors m...

We investigate the origin of undesirable transverse cracks often observed in thin films obtained by the layer transfer technique. During this process, two crystals bonded to each other containing a weak plan produced by ion implantation are heated to let a thin layer of one of the material on the other. The level of stress imposed on the film during the heating phase due to the mismatch of ther...

The input data for DNA computing must be encoded into the form of single or double DNA strands. As complementary parts of single strands can bind together forming a double-stranded DNA sequence, one has to impose restrictions on these sets of DNA words (=languages) to prevent them from interacting in undesirable ways. We recall a list of known properties of DNA languages which are free of certa...

25 26 This article describes the development, validation and application of a rapid screening method 27 for the detection and identification of undesirable organic compounds in aquaculture products. 28 A generic sample treatment was applied without any purification or preconcentration step. After 29 extracting the samples with acetonitrile/water 80:20 (0.1% formic acid), the extracts were 30 ce...

1,4-Benzoquinones have been found to prevent olefin isomerization of a number of allylic ethers and long-chain aliphatic alkenes during ruthenium-catalyzed olefin metathesis reactions. Electron-deficient benzoquinones are the most effective additives for the prevention of olefin migration. This mild, inexpensive, and effective method to block olefin isomerization increases the synthetic utility...

Determining the optimal scale size of a combined cycle power plant is inherently a complex problem often with multiple and conflicting criteria as well as uncertain factors. The complexity of the problem is compounded by the production of undesirable outputs and the presence of natural and managerial disposability. We propose a customized data envelopment analysis (DEA) method for solving the r...
