The Internet is becoming the main source for various tasks, from learning, to working, and shopping. There are many websites one can use to shop. Almost all stores have a website from which you can order anything you might want. As online shopping becomes more prominent, it is important to understand the effects of the Internet and its product reviewers and, specific to this study, consumer decision making.

Show moreThe Internet is becoming the main source for various tasks, from learning, to working, and shopping. There are many websites one can use to shop. Almost all stores have a website from which you can order anything you might want. As online shopping becomes more prominent, it is important to understand the effects of the Internet and its product reviewers and, specific to this study, consumer decision making. This study seeks to understand the effect of star ratings and valence on review perception between the different cognitive levels of individuals. Recognition review perception, and intent to purchase were being measured. Results showed that need for cognition did have an effect on accuracy of recognition and perceived valence. Need for cognition and congruency as well as actual valence had an effect on perceived valence. Need for cognition, actual valence, and congruency all had an effect on purchase intention. This research is important because it is relevant to a growing trend around the world. Technology is already integrated into nearly everyone's lives and it is only going to more so as we continue to evolve. Just as it is becoming more common for people to receive education from online institutions, and for employers to use more Internet based applications, it is only natural consumers will continue the trend of purchasing items online. Learning the social and cognitive influences of online reviews on perception and purchasing intentions is something everyone needs to be aware of.

Misconceptions are widespread or commonly held beliefs explicitly contradicted by empirical evidence. When teachers harbor misconceptions or unjustified beliefs about teaching, learning, and human motivation, the potential pedagogical consequences are profound, and these inaccurate beliefs may be instilled into future students through ineffective teaching strategies and gross misinterpretations of learning science.

Show moreMisconceptions are widespread or commonly held beliefs explicitly contradicted by empirical evidence. When teachers harbor misconceptions or unjustified beliefs about teaching, learning, and human motivation, the potential pedagogical consequences are profound, and these inaccurate beliefs may be instilled into future students through ineffective teaching strategies and gross misinterpretations of learning science. While existing research has examined misconceptions about general psychology and neuroscience among various populations, no prior work has evaluated pre-service teachers' misconceptions about topics of educational psychology, comprising inaccurate beliefs about teaching, learning, and human motivation. The purpose of this research is to describe the development and validation of a scale to measure misconceptions about educational psychology among pre-service teachers. Employing an experimental 2 (scale: true/false, six-point Likert-type) x 2 (valence: positive, mixed) x 2 (order: true/false presented first, Likert-type presented first) factorial, repeated measures design, a randomized experiment was performed to systematically evaluate the conditions under which the proposed scale for misconceptions of educational psychology performed best. As expected, the Likert-type scale was more sensitive to detecting misconceptions relative to the true/false scale. However, contrary to extant research on the valence effect, mixed-valence scales outperformed the positively-valenced scales across conditions indicating that misconceptions are best measured with a Likert-type response format using a heterogeneous mix of positively- and negatively-valenced items rather than a homogeneous set of positively-valenced items. Implications for practice and future research are discussed.

Faking on self-report personality tests is a widespread practice which degrades the construct validity of personality tests when they are used in personnel selection contexts and may lead to suboptimal hiring decisions (Donovan, Dwight, (&) Hurtz, 2003; Schmit (&) Ryan, 1993). While much is known about the factors which enable job applicants to successfully engage in faking (Tett, Freund, Christiansen, Fox, (&) Coaster, 2012), far less is known about how specific applicant perceptions...
Show moreFaking on self-report personality tests is a widespread practice which degrades the construct validity of personality tests when they are used in personnel selection contexts and may lead to suboptimal hiring decisions (Donovan, Dwight, (&) Hurtz, 2003; Schmit (&) Ryan, 1993). While much is known about the factors which enable job applicants to successfully engage in faking (Tett, Freund, Christiansen, Fox, (&) Coaster, 2012), far less is known about how specific applicant perceptions throughout the hiring process influence their decision to engage in this practice. To this end, this study applied Vroom's (1964) expectancy theory to the study of applicant faking. Following the work of prior researchers (Peterson, Griffith, (&) Converse, 2009), this study incorporated an experimental paradigm in which participants were led to believe that they were completing a personality test as part of the hiring process.Results of the study suggested that applicant faking on personality tests within personnel selection contexts is largely driven by valence (the extent to which applicants perceive the job to which they are applying as desirable) and expectancy judgments (an applicant's self-efficacy regarding their ability to successfully engage in faking). However, the three-way interaction between valence, instrumentality, and expectancy judgments which forms the crux of Vroom's (1964) theory did not demonstrate a significant impact on subsequent faking. A positive relationship between cognitive ability and faking was also found, suggesting that highly intelligent job applicants are more prone to engage in this behavior. In addition, applicant integrity demonstrated no relationship to faking behavior, suggesting that job applicants may not view the practice as being unethical. The potential implications of these findings in real-world selection contexts was discussed.

Copper (Cu) compounds are widely used as effective agricultural bactericides. Continuous use of these materials has led to Cu accumulation in soil over time. The United States Environmental Protection Agency (US EPA) is concerned about potential Cu contamination in the environment. Improving biocidal efficacy of Cu is an attractive alternative, allowing reduction of Cu amount per application.

Show moreCopper (Cu) compounds are widely used as effective agricultural bactericides. Continuous use of these materials has led to Cu accumulation in soil over time. The United States Environmental Protection Agency (US EPA) is concerned about potential Cu contamination in the environment. Improving biocidal efficacy of Cu is an attractive alternative, allowing reduction of Cu amount per application. In this research, we focused on making water-soluble mixed-valence Copper/Silica composite nanogel (CuSiNG) material. The objective is to improve the efficacy of Cu by manipulating Cu valence states. It has been shown in the literature that Cu (0) and Cu (I) states are more potent that Cu (II) states in terms of their antimicrobial efficacy. It is hypothesized that mixed valence Cu will exhibit improved efficacy over Cu (II). A water-soluble mixed valence Cu/silica nanogel (MV-CuSiNG) composite has been synthesized and characterized. Structure, morphology, crystallinity and composition of the MV-CuSiNG material was characterized using High-Resolution Transmission Electron Microscopy (HRTEM), HRTEM Selected Area Electron Diffraction (SAED) and X-ray Photoelectron Spectroscopy (XPS). Amount of Cu loading in MV-CuSiNG composite material was estimated by Atomic Absorption Spectroscopy (AAS). To confirm presence of Cu (I) in the MV-CuSiNG material, Neocuproine (Nc, a Cu (I) specific chelator) assay was used. Antimicrobial efficacy of MV-CuSiNG and CuSiNG was evaluated against X.alfalfae, B.subtilis and E.coli using Kocide(&)#174; 3000 ((")Insoluble Cu (II)(") compound), Copper sulfate ((")Soluble Cu (II)(") compound) and Cuprous chloride (Copper (I) compound) as positive controls and silica (")seed(") particles (without Cu loading) as negative control. Antimicrobial studies included observing bacterial growth inhibition and determining the Minimum Inhibitory Concentration (MIC). Improved antimicrobial efficacy was observed in MV-CuSiNG when compared to CuSiNG and other controls. For the assessment of plant safety of MV-CuSiNG and CuSiNG materials, phytotoxicity studies were conducted using Vinca sp and Hamlin orange under environmental conditions. It was observed that MV-CuSiNG material was safe to plants at commercially used (standard) spray application rate.
