Il calore del sole diventa energia frigorifera sostenibile economicamente ed energticamente. Gli sviluppi tecnologici degli ultimi anni nel campo dellâenergia solare consentono consentono di realizzare quanto apparentemente in contraddizione con i fondamentali teoremi della fisica classica ed in particolare della termodinamica. Questo elaborato vuole analizzare come, se e in quali casi sia conveniente l'installazione di un impianto di solar cooling per la climatizzazione estiva di un edificio. Partendo dal problema, sempre più attuale, dei crescenti consumi di energia elettrica per il condizionamento estivo degli edifici, dalla ricerca bibliografica è emerso come inizi a farsi strada, come soluzione percorribile e logicamente interessante, lâutilizzo dellâenergia solare, fruttata in impianti che prendono il nome di impianti di solar cooling.

In an effort to understand some of the ways that accountability-based reform efforts have influenced teacher education, this article details the politics of accountability in Pennsylvania that motivated sweeping changes in the policies governing teacher preparation in 2006. This case study provides a poignant example of the kind of complex accountability systems now being constructed across the United States in an effort to change teacher preparation. By analyzing primary documents including the legal statutes governing teacher preparation in Pennsylvania, correspondence from the Pennsylvania Department of Education, related newsletters, memos, reports, transcripts of meetings, and testimony before the Pennsylvania House of Representatives, the complex nature of the conflicts underlying the development and implementation of teacher education reform is brought into focus. The study's findings suggest that a deep and uncritical acceptance of accountability-based teacher education reform on the part of educational policy makers is likely to do more harm than good. The article concludes by outlining a framework for developing more intelligent measures of accountability that might preserve professional autonomy and judgment.

Examined the amount of money bet during a week of Pennsylvania's Daily Number game. In this game, players receive a predetermined payoff for picking the 3-digit number (000 to 999) drawn on that day. The betting distribution was distinctly nonuniform. Several betting patterns were identified, such as picking triples and avoiding double 9s. In addition, 121 adults and 215 students were asked to rate selected numbers for randomness, luckiness, and perceived history of winning; to categorize numbers; and to free associate to numbers. It is proposed that people seem to choose highly patterned, available, and/or "lucky" numbers. People apparently do not bet numbers that reflect the random process of the game (do not utilize a representativeness heuristic).
