Android devices have gained a lot of attention in the last few decades due to several reasons including ease of use, effectiveness, availability and games, among others. To take advantage of Android devices, mobile users have begun installing an increasingly substantial number of Android applications on their devices. Rapid growth in many Android devices and applications has led to security and privacy issues. It has, for instance, opened the way for malicious applications to be installed on the Android devices while downloading different applications for different purposes. This has caused malicious applications to execute illegal operations on the devices that result in malfunction outputs. Android botnets are one of these malfunctions. This paper presents Android botnets in various aspects including their security, architecture, infection vectors and techniques. This paper also evaluates Android botnets by categorising them according to behaviour. Furthermore, it investigates the Android botnets with respect to Android device threats. Finally, we investigate different Android botnet detection techniques in depth with respect to the existing solutions deployed to mitigate Android botnets.
Our objective is to enable the blind to use smartphones with touchscreens to make calls and to send text messages (sms) with ease, speed, and accuracy. We believe that with our proposed platform, which enables the blind to locate the position of the keypads, new games and education, and safety applications will be increasingly developed for the blind. This innovative idea can also be implemented on tablets for the blind, allowing them to use information websites such as Wikipedia and newspaper portals.
Coaches are the people responsible for helping athletes work towards
achieving their full potential. The influence of coaches is associated with
positive impacts on athletes by enhancing their performance, character
development, athlete satisfaction and other various positive outcomes. In
order to develop successful athletes, coaches need to have a high level of
coaching efficacy. Many factors may affect coaching efficacy, such as
coaching education and experience, and it might play a part in the ability of
coaches in coaching their athletes. Hence, the purpose of this study is to
determine the impact of coaching experience and education on coaching
efficacy among Malaysian collegiate coaches. A total of 331 coaches for
SUKIPT 2016 were involved in this study. The Coaching Efficacy Scale
(CES) questionnaire was used to measure the coaches coaching efficacy.
Overall, Malaysian collegiate coaches showed that their level of coaching
efficacy was high for all subscales, namely character building (M=7.92,
SD=.83), technique (M=7.91, SD=.89), game strategy (M=7.80, SD=.93), and
motivation (M=7.79, SD=.83). Furthermore, study shows that there was a
medium positive correlation between coaching experience (r=.37, n=331,

Online gaming has greatly increased in popularity in recent years, and with this has come a multiplicity of problems due to excessive involvement in gaming. Gaming disorder, both online and offline, has been defined for the first time in the draft of 11th revision of the International Classification of Diseases (ICD-11). National surveys have shown prevalence rates of gaming disorder/addiction of 10%-15% among young people in several Asian countries and of 1%-10% in their counterparts in some Western countries. Several diseases related to excessive gaming are now recognized, and clinics are being established to respond to individual, family, and community concerns, but many cases remain hidden. Gaming disorder shares many features with addictions due to psychoactive substances and with gambling disorder, and functional neuroimaging shows that similar areas of the brain are activated. Governments and health agencies worldwide are seeking for the effects of online gaming to be addressed, and for preventive approaches to be developed. Central to this effort is a need to delineate the nature of the problem, which is the purpose of the definitions in the draft of ICD-11.
