Arousal, rank and utility

We apply Maslow’s hierarchy of needs to the concept of utility and then go on to a new model where individual’s behavior is aimed at reaching optimal level of arousal of neural system and optimal level of domination in social ranking.utility, motivation, altruism, demonstration of wealth, novelty, comfort, rank, arousal

A Position of Influence: Variation in Offender Identification Rates by Location in a Lineup

Researchers have identified several threats to the validity of the use of the lineup as a test of true recognition. One concern is related to the structure of the simultaneous lineup. It is argued here that a simultaneous presentation of an array nonetheless requires the viewer to undertake sequential processing of the items in the array. This sequential pattern is unlikely to be random and therefore the position of a culprit in a lineup may have a significant effect on the accuracy of witness selection. A simulated crime (snatching of a handbag) was shown to a convenience sample of 84 undergraduates aged between 18–23 years. In 84 subsequent live lineups, the offender was placed with four foils. He was positioned on the far left (position 1) in 42 cases (50%), and in 14 cases respectively in positions 3 (centre), 4 (centre right) and 5 (extreme right). A very strong association was found between position and correct identification with position 1 placement leading to a significantly lower proportion of correct identification (7.1%) compared to position 3 (50.0%), position 4 (64.3%), and position 5 (21.4%). Steps to remedy possible positional biases are considered

Human capital, innovation and the productive ageing: growth and senior aged health in the regional community through engaged higher education

[Abstract]: This paper examines how low relative economic growth and high service and infrastructure costs in non-metropolitan regions that are increasingly attractive to lifestyle-seeking seniors, can be offset by focussing more positively on the human capital dimension of this cohort through closer engagement with higher education learning and innovation. At present, many senior-aged persons attracted to ‘lifestyle’ locations are allowed to let their knowledge, networks and skills ossify through a lack of engagement with processes of learning and innovation and institutional impediments of a structural and attitudinal nature. It represents poor return on sunk investment in human capital, has cost impacts on enabling health and community services and infrastructure and does not contribute as positively as it could to regional growth outcomes through productivity gains. The spatial impact of this will exacerbate as the demographic profile of the nation continues to age. Higher education in these places could be a key instrument in the learning and innovation required to realise the greater productivity gains from senior-aged human capital and the consequential growth and health outcomes at the local and regional scale. The paper reports on the literature, research undertaken and analysis to understand these potentially important issues of policy and practice. The paper has a particular focus on the Sunshine Coast and Wide Bay Burnett regions of Queensland which have some of the highest concentrations of senior aged people in Australia

Do individual investors learn from their trading experience

This paper investigates whether individual investors adjust their stock trading according to their stock selection abilities, which can be inferred from their trading history. Fixed-effect panel regressions provide strong evidence that the ability to forecast future stock returns significantly affects investors’ trading activity: investors purchase more actively if they are more likely to have stock selection ability. Furthermore, trading experience – measured by the number of purchases, the number of different stocks purchased, and the variance of purchase dollar amounts – significantly helps improve investors’ portfolio performance. In addition, we find that learning behavior varies across investors, which corroborates the heterogeneity of individual investorsindividual investors, learning, rationality, trading

Getting connected- at what cost? Some ethical issues on mobile HCI

The large scale deployment of mobile applications inevitably affects our daily lives and the whole culture. Not all of these effects are desirable. In a market economy, ethical issues are not the foremost drivers in the development of technology. In this paper, we ask whether the mobile human-computer interaction community could take an active role in discussing the issues which really matter in the development of technology for human beings, rather than concentrating on the fine tuning of emerging gadgets

Adding Salt to Pepper: A Structured Security Assessment over a Humanoid Robot

The rise of connectivity, digitalization, robotics, and artificial intelligence (AI) is rapidly changing our society and shaping its future development. During this technological and societal revolution, security has been persistently neglected, yet a hacked robot can act as an insider threat in organizations, industries, public spaces, and private homes. In this paper, we perform a structured security assessment of Pepper, a commercial humanoid robot. Our analysis, composed by an automated and a manual part, points out a relevant number of security flaws that can be used to take over and command the robot. Furthermore, we suggest how these issues could be fixed, thus, avoided in the future. The very final aim of this work is to push the rise of the security level of IoT products before they are sold on the public market.Comment: 8 pages, 3 figures, 4 table

Investigating the relationship of brand experience and loyalty: A study of luxury brand in Thailand

The concept of 'brand experience' has evolved as an imperative arena of study in the marketing discipline. Although the importance and the concept of experience have been adapted in marketing such as customer experience, consumption experience and so on, the explanations of brand experiences have remained vague and absent a thorough theoretical foundation. This research aims to understand the concept of 'brand experience' and its impact of consumer behaviour (loyalty) direct or indirect through brand personality, satisfaction or [and] brand trust in the luxury brand context (Thailand). This research is carried out in one stage 'quantitative'. Furthermore the research data will be collected based on distributing survey questionnaire. Among of 400 Thai citizen samples will be surveyed to measure a modify framework from (Brakus et al, 2009). The result will provide meaningful information in both academic research and marketing practice. Furthermore, it will be presented the prediction of consumer behaviour via brand experience. Moreover, it guides marketers to various marketing strategy option such as experiential marketing or traditional marketing

On environments as systemic exoskeletons: Crosscutting optimizers and antifragility enablers

Classic approaches to General Systems Theory often adopt an individual perspective and a limited number of systemic classes. As a result, those classes include a wide number and variety of systems that result equivalent to each other. This paper introduces a different approach: First, systems belonging to a same class are further differentiated according to five major general characteristics. This introduces a "horizontal dimension" to system classification. A second component of our approach considers systems as nested compositional hierarchies of other sub-systems. The resulting "vertical dimension" further specializes the systemic classes and makes it easier to assess similarities and differences regarding properties such as resilience, performance, and quality-of-experience. Our approach is exemplified by considering a telemonitoring system designed in the framework of Flemish project "Little Sister". We show how our approach makes it possible to design intelligent environments able to closely follow a system's horizontal and vertical organization and to artificially augment its features by serving as crosscutting optimizers and as enablers of antifragile behaviors.Comment: Accepted for publication in the Journal of Reliable Intelligent Environments.
