On altruists and egoists in activity participation and travel: who are they and do they live together?

Formulation and specification of activity analysis models require better understanding of time allocation behavior that goes beyond the more recent within household analyses to understand selfish and altruistic behavior and how this relates to travel behavior. Using data from 1,471 persons in a recent 2-day time use/activity diary and latent class cluster analysis we identify 11 distinct daily behaviors that span from the intensely self-serving to intensely altruistic. Predicted cluster membership is then used to study within household interactions. The analysis shows strong correlation exists between social role and patterns of altruistic behavior. However, a substantial amount of heterogeneity is also found within social roles. In addition, travel behavior is also very different among altruistic and self-serving time allocation groups. At the household level, a substantial number of households contain persons with similar behavior. Another group of households contains a mix of self-serving and altruistic persons that follow specialized household roles within their households. The majority of households, however, are populated by altruistic persons. Single person households are more likely to be in the self-serving groups but not in their entirety. Altruism at home is directed most often toward the immediate family members. This is less pronounced when we examine altruistic acts outside the home. Konstadinos G.

我国未来民法典限制政府官员隐私权的宪政意义

限制政府官员的隐私权，意味着媒体权力在其私域可以得到相应的扩张。这在选任、监督以及激励政府官员上，对于人民具有重大意义；对于政府官员而言，其也并非百无一利。故人民即便是在对政府官员因其隐私权受限而可能遭受的利益减损进行相应补偿后，也仍可从中获取较大利益。我国于即将制定的民法典中规定限制政府官员隐私权的条款具有重大的宪政意义。
