Consumers' perceptions of QR codes

In recent years, Quick Response Codes (QR Codes) have gained significant momentum in the United States as a use for marketing communications on product packaging (Sago, 2011). In this study, the authors will propose an experiment, survey, and interview. The intended purpose of this study will be to analyze consumer’s perceptions of the current knowledge and effectiveness of QR Codes. The experiment will be constructed to analyze consumers’ perceptions of the physical QR Codes on the packaging. The survey will be designed to produce data concerning consumers’ current knowledge and perception of effectiveness of QR Codes accomplishing the marketer’s goal for the QR Code. The interview will be used to collect qualitative data to gain understanding of how consumers would like companies to use QR Codes - that is if they think they should use them at all.

Tattoo ink nanoparticles in skin tissue and fibroblasts

YesTattooing has long been practised in various societies all around the world and is becoming increasingly common and widespread in the West. Tattoo ink suspensions unquestionably contain pigments composed of nanoparticles, i.e., particles of sub-100 nm dimensions. It is widely acknowledged that nanoparticles have higher levels of chemical activity than their larger particle equivalents. However, assessment of the toxicity of tattoo inks has been the subject of little research and ink manufacturers are not obliged to disclose the exact composition of their products. This study examines tattoo ink particles in two fundamental skin components at the nanometre level. We use atomic force microscopy and light microscopy to examine cryosections of tattooed skin, exploring the collagen fibril networks in the dermis that contain ink nanoparticles. Further, we culture fibroblasts in diluted tattoo ink to explore both the immediate impact of ink pigment on cell viability and also to observe the interaction between particles and the cells

Assessment of novel gear designs to reduce interactions between species

This project tested modified gillnets designed by commercial net fishers in the Queensland East Coast Inshore Finfish Fishery (ECIFF) to try and identify gears that would mitigate and/or improve interactions between fishing nets and Species of Conservation Interest (SOCI). The study also documents previously unrecognised initiatives by pro-active commercial net fishers that reflect a conservation-minded approach to their fishing practices, which is the opposite of what is perceived publicly. Between 2011 and 2014, scientists from James Cook University and the Queensland Department of Agriculture and Fisheries teamed with commercial fishers representing the Queensland Seafood Industry Association and the Moreton Bay Seafood Industry Association to conduct field trials of various modified net designs under normal fishery conditions. Trials were conducted in Moreton Bay (southern part of the fishery) and Bowling Green Bay (northern) and tested different net designs developed by fishers to improve the nature of interactions between net fishing gear and SOCI

Leadership characteristics in the immigrant community

The objective of this study is to understand the immigrant community perception of leadership and its characteristics. We want to know what qualities they would assign to leaders. The study also investigates the community perception of the following leadership characteristics: decisionmaking, associations, perception, and ease of leadership. Decision-making relates to how the decision-making is determined in general by immigrants. For example, if decisions are made with a conscious awareness of how it affects others, if the decisions are made for personal benefit, if decisions are made using a cost benefit analysis, etc. .We analyze associations based on past relationships that influence good leadership in immigrant. Ease of leadership is analyzed by the perceived amount of difficulty associated with leadership. All factors are related to their effect on the immigrant community. There are multiple studies that analyze and interpret leadership factors and qualities among immigrant or minority communities. Leader to Leader discusses whom different families coming from different cultural backgrounds and areas (Leadership, 2005). Another study focused on how cultural factors influence leadership among immigrants and how these characteristics affect operations in their respective organizations (Yun-His, 2011). This study is important in understanding other cultures and their views on leadership. It also allows people to help create better leaders based on the results we may find.

Sensitivity analysis of the variable demand probit stochastic user equilibrium with multiple user classes

This paper presents a formulation of the multiple user class, variable demand, probit stochastic user equilibrium model. Sufficient conditions are stated for differentiability of the equilibrium flows of this model. This justifies the derivation of sensitivity expressions for the equilibrium flows, which are presented in a format that can be implemented in commercially available software. A numerical example verifies the sensitivity expressions, and that this formulation is applicable to large networks
