Life goals predict environmental behavior: cross-cultural and longitudinal evidence

Prioritizing intrinsic life goals (self-development, community involvement, relationships) rather than extrinsic ones (money, fame, image) is said to foster not only personal wellbeing, but also pro-social behavior such as protecting the environment. We explored concurrent and prospective links between intrinsic (versus extrinsic) life goals and self-reported environmentally responsible behavior, using correlational and longitudinal data from adult participants in a mass consumer society (UK) and a fast developing nation (Chile). In both countries, the importance of intrinsic (versus extrinsic) life goals was associated cross-sectionally with environmentally responsible behavior, even after controlling for possible effects of environmental worldviews and environmental identification. In longitudinal analyses, life goals prospectively predicted environmentally responsible behavior over a two-year period, whereas, rather unexpectedly, environmental worldviews and environmental identification did not. We conclude that focusing on intrinsic, rather than extrinsic, life goals may be important not just for individuals’ well-being, but also for the well-being of future generations

Harvesting RF Energy- A Review

There is a demand of power at remote locations for many applications such as charging of batteries for WSN. Due to advancement in technology, many devices operate at low power level. The RF energy can be harvested and fed to these devices on board. RF signal is available globally and energy can be harvested from this signal. It is available at all times and can be used as source of energy for low power devices. RF harvesting unit consists of three modules, Antenna, Matching network and Rectifier circuit. This paper presents an overview of each stage of RF harvesting architecture. The paper introduces designed antennas, factors affecting the different parameters of antenna like bandwidth, gain and efficiency. Design of antenna with miniaturization, harmonic rejection and frequency selectivity is explained. The comparative study of matching network such as L type, π type and microstrip line is described for maximum power transfer and different rectifier circuits for RF to DC conversion are discussed
