The levels of crime and violence in South Africa are at a very alarming and concerning rate. It is against this background that, this situation is treated as a matter of urgency by the South African presidency, government departments, civil society organisations and business sector to prevent and decreace the possibility of ruined socio-economic development in South Africa.Heedful to the status quo of the South African crime levels, the implementing of the integrated social crime prevention strategy was approved by the Sourth African presidency as a comprehensive and an appropriate framework to deal with the high levels of crime and to create opportunities for safety in South Africa (Presidency, 2010).The goal of this study was to explore the inherent approaches to implementing the integrated social crime prevention strategy in South Africa. In exploring this goal and objectives of the study, the researcher used Tech’s (in Creswell, 1994) data analysis framework to identify appropriate approaches to implementing the integrated social crime prevention strategy in South Africa.The findings in the study have shown that alternative approaches are crititical to implementing the integrated social crime prevention stategy in South Africa to foster integrated and collaborative delivery of services by all government department, civil society otganisation and private sector. It is also evident that, the recommendations of this study can be used as a guideline by different sectors to improve the implementation of the strategy in South Africa.The following are the key words used throughout the study: approach, implementation, integrated, social crime prevention and strategy which answered the primary research question: What are the inherent approaches to implementing the integrated social crime prevention strategy in South Africa. These words are defined in chaper one (1).

Synaptic plasticity is a fundamental feature of the nervous system that allows adaptation to changing behavioral environments. Most studies of synaptic plasticity have examined the regulated trafficking of postsynaptic glutamate receptors that generates alterations in synaptic transmission. Whether and how changes in the presynaptic release machinery contribute to neuronal plasticity is less clear. The SNARE complex mediates neurotransmitter release in response to presynaptic Ca[superscript 2+] entry. Here we show that the SNARE fusion clamp Complexin undergoes activity-dependent phosphorylation that alters the basic properties of neurotransmission in Drosophila. Retrograde signaling following stimulation activates PKA-dependent phosphorylation of the Complexin Cterminus that selectively and transiently enhances spontaneous release. Enhanced spontaneous release is required for activity-dependent synaptic growth. These data indicate that SNAREdependent fusion mechanisms can be regulated in an activity-dependent manner and highlight the key role of spontaneous neurotransmitter release as a mediator of functional and structural plasticity.

Pokémon Go arguably depicts the most popular adoption of augmented reality (AR) technology on any platform and particularly mobile games during the conduct of this research. The mobile location-based game was launched in July 2016, to the delight of millions of people globally. Pokémon Go requires people to physically navigate the real world in the course of playing the game; this was a relatively new experience for many especially as a mobile game. The need to physically navigate the real world in Pokémon Go prompted the quest to examine what impacts Pokémon Go has on college students. Specifically, we focus on the impact on their social interaction and physical activity as there were studies that have shown that traditional mobile games and video games have made people become anti-social, adopt sedentary lifestyles resulting in various issues in social and health aspects. This research aims to acquire a better understanding of how AR games like Pokémon Go impacts social interaction and physical activity, and to recommend guidelines for developing similar augmented reality games to promote social interaction and physical activity. Semi-structured interviews were conducted with twenty participants attending a college in the mid-western region of the United States of America. Our findings revealed that Pokémon Go encouraged increased social interaction among family, friends and strangers. Participants also enjoyed some health and educational benefits as a result of playing Pokémon Go. We also identified some challenges and concerns of playing Pokémon Go which borders on personal safety and security, circumvention of game design as well as privacy. Our findings led us to propose recommendation for augmented reality game design that will promote social interaction and physical activity. These include incorporating social game components to enhance players’ overall gaming experience, addressing game design circumvention by developing algorithms that will intelligently permit cheating or out rightly prevent cheating. We also recommended a more transparent and flexible permission requests to address privacy concerns.
