An app for personal searches:more-private, non-volatile searches with stigmergic inspiration

Web searching has long become a ubiquitous behavior amongst Internet users. Much has been changing: odds are that the thousands of results of yesterday have become millions of results today, but did that significant jump in quantity translate to an increase in the perceived results' quality and their applications? Some users might feel personalization efforts as stereotypification or even as inaccurate biases; they may also beware that every click on every search result may reinforce and contribute to (in)accurate representation of them - and would prefer searching without tracking. "Personal Searcher" is a work-in-progress app that makes it possible to search more anonymously. It also makes it possible to keep a private local-only history of one's searches and build personal ranking systems based on that history and other data. The goal is to benefit from local offline personalization, but search online as anonymously as possible.N/

Gangs, displaced, and group-based aggression

Many urban areas experienced an alarming growth of gang activity and violence during the end of the 20th and the beginning of the 21st centuries. Gang members, motivated by various factors, commit a variety of different types of violent acts towards rivals and other targets. Our focus involves instances of displaced aggression, which generally refers to situations in which aggression is targeted towards individuals who have either not themselves committed an offense against the aggressor (s), or who provide an offense that is too mild to justify the aggression levels that are expressed towards them. We discuss how social–psychological mechanisms and models of two types of displaced aggression might help explain some aspects of the retaliatory behavior that is expressed by members of street gangs. We also propose general techniques that have the potential to reduce such aggressive behavior

The Importance of Transparency and Willingness to Share Personal Information

This study investigates the extent to which individuals are willing to share their sensitive personal information with companies. The study examines whether skepticism can influence willingness to share information. Additionally, it seeks to determine whether transparency can moderate the relationship between skepticism and willingness to share and whether 1) companies perceived motives, 2) individual’s prior privacy violations, 3) individuals’ propensity to take risks, and 4) individuals self-efficacy act as antecedents of skepticism. Partial Least Squares (PLS) regression is used to examine the relationships between all the factors. The findings indicate that skepticism does have a negative impact on willingness to share personal information and that transparency can reduce skepticis

The influence of national culture on the attitude towards mobile recommender systems

Changes may have been made to this work since it was submitted for publication. Copyright @ 2013 Elsevier B.V.This study aimed to identify factors that influence user attitudes towards mobile recommender systems and to examine how these factors interact with cultural values to affect attitudes towards this technology. Based on the theory of reasoned action, belief factors for mobile recommender systems are identified in three dimensions: functional, contextual, and social. Hypotheses explaining different impacts of cultural values on the factors affecting attitudes were also proposed. The research model was tested based on data collected in China, South Korea, and the United Kingdom. Findings indicate that functional and social factors have significant impacts on user attitudes towards mobile recommender systems. The relationships between belief factors and attitudes are moderated by two cultural values: collectivism and uncertainty avoidance. The theoretical and practical implications of applying theory of reasoned action and innovation diffusion theory to explain the adoption of new technologies in societies with different cultures are also discussed.National Research Foundation of Korea Grant funded by the Korean governmen

Young children learning with mobile devices: Research on design and implementation

The increasing growth and usage of mobile devices, such as tablets and iPads, by young children has not yet been accompanied by systematic research about the effects they have on children's learning and the conditions that facilitate or hinder learning and engagement. As a result, only few empirically-based guidelines exist to guide parents, educators, and application (app) designers when choosing or designing apps for young children, often leading to non-evidence-based decisions, or the design of apps with little educational value. This symposium aims to bring together researchers from Australia, the UK and USA to discuss what evidence exist about the learning potential of mobile devices and apps for young children and how it could be used to inform relevant stakeholders

Psychological elements explaining the consumer's adoption and use of a website recommendation system: A theoretical framework proposal

The purpose of this paper is to understand, with an emphasis on the psychological perspective of the research problem, the consumer's adoption and use of a certain web site recommendation system as well as the main psychological outcomes involved. The approach takes the form of theoretical modelling. Findings: A conceptual model is proposed and discussed. A total of 20 research propositions are theoretically analyzed and justified. Research limitations/implications: The theoretical discussion developed here is not empirically validated. This represents an opportunity for future research. Practical implications: The ideas extracted from the discussion of the conceptual model should be a help for recommendation systems designers and web site managers, so that they may be more aware, when working with such systems, of the psychological process consumers undergo when interacting with them. In this regard, numerous practical reflections and suggestions are presented

WIRELESS ADVERTISING: A STUDY OF MOBILE PHONE USERS

Using a qualitative methodology, this study attempts to provide a general framework of the functions of mobile communication, and to identify the specific preferences of mobile phone users regarding the commercial messages received on their personal devices. Research objectives: (1) To identify the specific characteristics of mobile communication as perceived by mobile users; (2) to define and analyze the functions of wireless communication as perceived by mobile phone users; and (3) to investigate users' preference regarding the content of commercial wireless communication. Previous research: Bauer et al. (2002) identified time, location, information and personalization as relevant acceptance factors for mobile advertising. Barwise and Strong (2002) developed a conceptual model, arguing that social norms, user's motives, mode, time, location and personal characteristics will affect the processing of mobile information by consumers. Tsang et al. (2004) evidenced the influence of entertainment, informativeness and irritation, while Bauer et al. (2005) argued that consumer attitudes are influenced by perceived information, entertainment, and social utility. In a similar study, Xu and Gutierrez (2006) tested the effect of entertainment, irritation, informativeness, credibility and personalization on the attitudes of Chinese consumers. Research methodology: First, a series of academic and practical articles and reports have been accessed in order to assess the existing knowledge on this topic. Second, five focus groups have been organized with six mobile phone users, aged between 20 and 40 years old. Each focus group comprised an equal number of male and female participants. The focus groups lasted between 45 and 60 minutes and addressed three main issues: the specific characteristics of the mobile phones as a commercial communication media, the functions of mobile phone communication, and the specific preferences of mobile phones users regarding the content of commercial messages. Findings: The participants demonstrated an active attitude regarding mobile advertising, which they think it has the potential to revolutionize the practice of commercial communication, by focusing more on consumer's personal needs and circumstances. Implications: This transformation cannot be realized without increasing the interactive control of mobile phone users' over the functionality and content advertising messages. Although the required technology already exists, it seems necessary to create new applications that can combine the advantages of customer-, product- and location- centered communication. Original contribution: Previous studies often used an analytical approach, highlighting specific variables regarding consumer perception or technology adoption. Using a qualitative methodology, this study provides a general framework of the functions of mobile communication, and identifies the specific preferences of mobile phone users regarding the commercial messages received on their personal devices.wireless advertising, mobile phones, functionality, content, users' opinions
