Persuasive gamified systems are effective tools for motivating behaviour change using various persuasive strategies. In line with the reinforcement theory, some persuasive gamified systems employ reward and punishment in their design to achieve the intended behavioural outcome. Research has argued both in favour and against using these strategies in behaviour change applications due to mixed results with respect to their effectiveness. However, there is a lack knowledge about how interventions using these strategies could motivate or demotivate behaviours. Therefore, this paper explores the mechanism through which Reward and Punishment motivate or demotivate behaviours with respect to their strengths and weaknesses. The results of large-scale exploratory studies (N = 1768) uncover important strengths and weaknesses that could facilitate or hinder the effectiveness of Reward and Punishment at motivating behaviour change. These include their ability to engage users and make behaviour fun, reinforce commitments to goals, and reveal some consequences of bad behaviour. We also compared the perceived effectiveness of reward and punishment quantitatively. [ABSTRACT FROM AUTHOR]

Assistive technologies have allowed people with disabilities to perform daily tasks with greater independence and autonomy, especially for visually impaired people. Using smart home solutions allows these users to control their homes with less cognitive and physical demand. However, making such applications accessible to meet the needs of visually impaired users, especially in developing countries, remains a challenge. This paper investigates the perceptions of these users about home automation technologies through semi-structured interviews. A total of 20 visually impaired people participated in the interviews. A thematic analysis revealed results concerning the following themes: (1) how people go about their lives at home and around, how people interact with current appliances, objects and environments, (3) how people perceive their attitude to technologies, (4) the Brazilian context of smart homes, (5) what people think smart homes should do and (6) envisaging ways of interacting with smart home systems. The results obtained provide significant insight into the needs of visually-impaired people in Brazil, with analysis of issues that are common with previous studies in more developed countries and specific issues that have important particularities and implications in Brazil and other developing countries.

This paper introduces a new electronic system for dropping courses that do not rely on the cumbersome paper system traditionally used by educational institutions. The new sub-system of the On-Demand University Services (ODUS Plus) will eliminate the hierarchical and inefficient paper system, which results in institutional delays. By using both quantitative and qualitative techniques, as well as a correlational methodology, it will be shown that, withdraw approval requests have streamlined, thus improving the system to process such requests. The following study will outline the efficacy of using ODUS Plus for course withdrawals by college and university administrators. The findings suggest that the implementation of such a system has a dual value; namely, it improves efficiency and functions as a source of knowledge regarding student academic preferences.

This paper presents an in-depth study of intra-disability diversity in the digital realm and the related role of individuality and selectiveness in the digital choices and experiences of people with disabilities (PwD). The study adopts the interactionist model of disability and problematises conceptual uniformity in research that focuses on the medical and socially-constructed features of disability as those determining digital constraints and affordances for PwD. Through primary qualitative evidence, it argues that individuality and selectiveness shape a complex terrain of intra-disability diversity, which forms the nuances and experiences of digital inclusion for PwD. Thus, it invites researchers to move beyond disability-fixed categorisations and offers a 3-tier recommendation for future research to explain the range of PwD' perceptions and experiences in the digital realm.
