The key highlights from the AVG Q4 2012 Threat Report are:
1) The Blackhole exploit kit dominated malware in 2012, accounting for 49% of attacks detected. It is a sophisticated, powerful, and heavily obfuscated exploit kit.
2) During 2012, mobile device penetration increased dramatically. Android is the most popular mobile OS, and thus attacks targeting Android have increased. Over 3.9 million mobile threats were detected by AVG in Q4 2012.
3) Exploit toolkits accounted for 60% of attacks in 2012. Established cybercriminals are creating commercial exploit toolkits that less technical criminals can use, fueling the rise in toolkit attacks.
The document provides tips on how businesses can protect themselves from cyber attacks. It begins by introducing common hacker tactics like phishing, exploiting wireless networks, and scanning for website vulnerabilities. It then discusses the types of attackers and their motives, usually to steal financial information or damage a company's reputation. Several specific attack vectors are outlined, including using default passwords, vulnerable websites, insecure wireless networks, flaws in internet banking, and social engineering through phishing emails. The presentation emphasizes adopting a "protect, detect, correct" mindset and classifying sensitive data, as well as following security best practices like enabling two-factor authentication, using strong unique passwords, and keeping software updated. The key message is that businesses of any size can take
Este documento presenta una guía de ejercicios sobre soluciones químicas para varios grupos de estudiantes. Incluye ejercicios sobre molaridad, normalidad y molalidad que involucran sustancias químicas disueltas en diferentes volúmenes de solución. Los estudiantes deben resolver los ejercicios correspondientes a su grupo y compartirlos con otros grupos. Todos los ejercicios deben entregarse resueltos en una carpeta para una fecha límite.
Strategies to modify the students conceptsSamia Dogar
The document discusses strategies for modifying children's ideas. It defines what a strategy is and dispels myths about children's abilities. The document then lists strategies teachers can use to modify students' ideas, including asking questions, providing direct experiences, making referrals using available resources, allowing group interactions and simulations, guided self-management, and creative projects. It states that ideas can be modified through a variety of strategies like acceleration, career investigation, enrichment, and addressing affective needs. Specific strategies mentioned include specialized curriculum, mentorship, learning contracts, testing out, college classes, counseling services, enrichment, pull-out programs, independent study, distance learning, grouping, differentiation, grade skipping, clubs, and student government.
This document discusses a project that used a 3D virtual world called Science Island to teach students about water and life through inquiry-based science education. Students explored Science Island using avatars and completed 10 steps of inquiry-based activities and experiments in both the virtual world and a real chemistry laboratory. Pre- and post-tests showed that the students who experienced the immersive virtual path improved their knowledge about water and life more than a control group who did not use Science Island. The project aims to understand how immersive virtual environments can influence learning, and students expressed a preference for this immersive education approach over traditional methods.

This document discusses concept mapping, which is a structured process that focuses on a topic of interest and produces an interpretable pictorial view of related ideas and concepts. It involves generating statements about a topic, sorting them into similar piles, rating their importance, analyzing the data to develop concept maps, and interpreting and using the maps. Concept mapping helps groups think together without losing individuality or trivializing details while managing complexity. Some advantages are that it overcomes communication ambiguities, avoids forcing consensus, embraces diversity, refocuses dialogue, allows emergent ideas, models complexity, and saves resources.
We ourselves create myths and miracles! This document suggests that humans have the ability to shape their own realities and beliefs through imagination and willpower rather than relying on external forces. In a concise yet positive manner, it emphasizes human potential and agency.
The SMART Tree project uses sap flow sensors installed on trees at multiple schools to engage students in hands-on plant science experiments. Students measure and compare water use of different tree species across different locations. Preliminary results show that rainfall events suppressed sap flow similarly in different species at different schools. The program aims to inspire students and improve science education by giving them experience with experimental design, data analysis, and sharing results internationally. It also benefits tree experts and the local community through development of a carbon trading program.
