Centrality of visual product aesthetics, tactile and uniqueness needs of fashion consumers

Abstract: The purposes of this study were to determine whether fashion consumer groups (fashion followers, fashion innovators, fashion opinion leaders and innovative communicators) differ in centrality of visual product aesthetics, consumers' need for uniqueness and need for touch, and to examine possible correlations among these variables. Fashion design and merchandizing students completed the following scales: Need for Touch, Consumers' Need for Uniqueness, Centrality of Visual Product Aesthetics, Measure of Fashion Innovativeness and Opinion Leadership plus demographic information. Innovative communicators had a greater need for uniqueness than followers and opinion leaders, but not than innovators. Fashion followers scored lower on Centrality of Visual Product Aesthetics than did innovative communicators, innovators and opinion leaders. There was no difference in Need for Touch among fashion consumer groups. Scores on Need for Touch were positively correlated with scores on Centrality of Visual Product Aesthetics and Consumers' Need for Uniqueness. Scores on Centrality of Visual Product Aesthetics were positively correlated with scores on Consumers' Need for Uniqueness. Scores on Fashion Innovativeness and Opinion Leadership were positively correlated with scores on Centrality of Visual Product Aesthetics and Consumers' Need for Uniqueness. Scores on Fashion Innovativeness and Opinion Leadership were not significantly correlated with those on Need for Touch. Fashion consumer groups did differ in centrality of visual product aesthetics and need for uniqueness, but not in need for touch.

Country of Origin and Foreign IPO Legitimacy: Understanding the Role of Geographic Scope and Insider Ownership:

Abstract: Foreign firms from emergent economies are increasingly seeking equity capital in developed economies like the United States. Utilizing institutional, signaling, and agency theories this research examines the legitimacy of foreign IPOs (initial public offerings) in the United States. Employing the population of foreign IPOs listed on U.S. stock exchanges between 1997 and 2004, it is demonstrated that firms from countries with governmental policies and institutional practices that protect the economic freedom of its citizens are significantly less underpriced than IPOs of firms originating from countries experiencing lower levels of economic freedom. The evidence further indicates that firms from emerging economies can overcome negative country perceptions associated with lower levels of legitimacy by increasing their international scope of operations prior to beginning the IPO process as well as by retaining acceptable levels of ownership in their respective firms.

Graphene Oxide as a Multifunctional Platform for Intracellular Delivery, Imaging, and Cancer Sensing.

Abstract: Graphene oxide (GO), the most common derivative of graphene, is an exceptional nanomaterial that possesses multiple physical properties critical for biomedical applications. GO exhibits pH-dependent fluorescence emission in the visible/near-infrared, providing a possibility of molecular imaging and pH-sensing. It is also water soluble and has a substantial platform for functionalization, allowing for the delivery of multiple therapeutics. GO physical properties are modified to enhance cellular internalization, producing fluorescent nanoflakes with low (<15%) cytotoxicity at the imaging concentrations of 15 μg/mL. As a result, at lower flake sizes GO rapidly internalizes into HeLa cells with the following 70% fluorescence based clearance at 24 h, assessed by its characteristic emission in red/near-IR. pH-dependence of GO emission is utilized to provide the sensing of acidic extracellular environments of cancer cells. The results demonstrate diminishing green/red (550/630 nm) fluorescence intensity ratios for HeLa and MCF-7 cancer cells in comparison to HEK-293 healthy cells suggesting a potential use of GO as a non-invasive optical sensor for cancer microenvironments. The results of this work demonstrate the potential of GO as a novel multifunctional platform for therapeutic delivery, biological imaging and cancer sensing.

The sweet smell of success: Apparent double alternation in the rat

Abstract: Fourteen rats received 104 acquisition and eight extinction trials in a 7 ft runway Reward and nonreward were administered in double-alternation sequences such that if on rewarded and nonrewarded trials Ss left characteristically different odors, then these odors could act as discriminative cues for subsequent Ss in Group P but not in Group NP Group P displayed a clear double-alternation pattern of running and extinguished rapidly, whereas Group NP’s responses were not patterned and it extinguished slowly This supports the hypothesis that rats exude odors which, depending on the manner in which the study is conducted, can serve as a powerful source of contamination among treatments or among Ss within a treatment
