Effectiveness of Installed Closed Circuit Television on Senior High School Behavioral Self-Control

It is important to explore how effective installed closed-circuit television (CCTV) cameras are to senior high school students when it comes to their behavioral self-control. Thus, this research aimed to determine the effectiveness of installed closed-circuit television on senior high school students’ behavioral self- control. This study employed a non-experimental descriptive research design and purposely included nearly 132 students for this study. Findings show that CCTV Cameras are highly effective in senior high school students’ behavioral self-control. The researchers found that CCTVs are highly effective in their behavioral self-control as it makes students feel self-conscious on being monitored with the known surveillance technology. Installed CCTV cameras also make them feel safe as it secures students in their educational institution premises. As observed and reviewed furthermore, sex has no significance in effectiveness of CCTV cameras as it makes both male and female feel the same with the known technology. This study concludes that CCTV cameras are highly effective to students on their behavioral self-control and being monitored makes them feel self-conscious about it but makes them feel safe and secured. Also, students aren't even bothered by CCTV cameras installed in their school premises because it gets them to remain well-behaved and keep on their schedules as students. To add, schools should do an evaluation for students about the surveillance cameras to entertain their concerns and thoughts to make possible room for improvements. Finally, this study recommends further exploration to determine if installed CCTV cameras are effective on not just for senior high school students, but also for the junior high school students as well. &nbsp

High Performance Ductile and Pseudo-ductile Polymer Matrix Composites: a Review

The ability of fibre reinforced composites to deform with a non-linear stress–strain response and gradual, rather than sudden, catastrophic failure is reviewed. The principal mechanisms by which this behaviour can be achieved are discussed, including ductile fibres, progressive fibre fracture and fragmentation, fibre reorientation, and slip between discontinuous elements. It is shown that all these mechanisms allow additional strain to be achieved, enabling a yield-like behaviour to be generated. In some cases, the response is ductile and in others pseudo-ductile. Mechanisms can also be combined, and composites which give significant pseudo- ductile strain can be produced. Notch sensitivity is reduced, and there is the prospect of increasing design strains whilst also improving damage tolerance. The change in stiffness or visual indications of damage can be exploited to give warning that strain limits have been exceeded. Load carrying capacity is still maintained, allowing continued operation until repairs can be made. Areas for further work are identified which can contribute to creating structures made from high performance ductile or pseudo-ductile composites that fail gradually
