A Compromise-resilient Pair-wise Rekeying Protocol in Hierarchical Wireless Sensor Networks 315 A Compromise-resilient Pair-wise Rekeying Protocol in Hierarchical Wireless Sensor Networks

Wireless sensor networks (WSNs) have been envisioned to be very useful for a broad spectrum of emerging civil and military applications (Akyildiz et al., 2002). However, sensor networks are also confronted with many security threats such as node compromise, routing disruption and false data injection, because they are normally operated in an unattended, harsh or hostile environment. Among all t...

a paradigm shift away from method-wise teaching to strategy-wise teaching: an investigation of reconstructive strategy versus communicative strategy

چکیده: هدف اصلی این مطالعه ی توصیفی تحقیقی در حقیقت تلاشی پساروش-گرا به منظور رسیدن به نتیجه ای منطقی در انتخاب مناسبترین راهکار آموزشی بر گرفته از چارچوب راهبردی مطرح شده توسط والدمر مارتن بوده که به بهترین شکل سازگار و مناسب با سامانه ی آموزشی ایران باشد. از این رو، دو راهکار آموزشی، راهکار ارتباطی و راهکار بازساختی، برای تحقیق و بررسی انتخاب شدند. صریحاً اینکه، در راستای هدف اصلی این پژوهش، ر...

Can the Internet be used to improve sexual health awareness in web-wise young people?

OBJECTIVES To assess Internet use amongst young people to determine whether it would be a practical way to provide sex education and information. METHODS Year 10 students (aged 14-15 years) from North Nottinghamshire schools were asked to participate in focus groups to discuss the Internet. A series of predefined questions were directed to the whole group to generate debate. Areas explored in...
