The Mate 8 has a solid 16-megapixel camera, the octa-core processor and 4GB of RAM keep it humming, and the giant 4,000 mAh battery lasts far longer than my iPhone. To be honest, I was surprised at how much I enjoyed carrying an Android phone again.
Externalizing and internalizing behaviors both result from negative responses to stress. Unlike internalizing behaviors, externalizing behaviors are focused outside of oneself. Whereas externalizing behaviors are easily observable by others, internalizing behaviors or not. For example, you can easily spot when a student is being physically aggressive toward another student (externalizing), but we cannot hear the negative self-talk (internalizing) that may be going through someone's head.
However, the externality also increases the aggregate cost to the economy and society, making it a negative externality. Externalities are negative when the social costs outweigh the private costs. Some externalities are positive. Positive externalities occur when there is a positive gain on both the private level and social level.
