JAMA: The Journal of the American Medical Association, 1993
Winters in North Carolina are always unpredictable. Mild but short summerlike days alternate with cold fronts that seem to bring new batches of colds. Crisp early-morning frosts harbinger an early flu season that strikes with such rapidity its victims know only that the timing is incredibly inconvenient.

2009 Third International Conference on Emerging Security Information, Systems and Technologies, 2009
Our study analyses possibilities of misusing social network sites due to irresponsible behaviour of users. Recent surveys show that problems of social network are more often to occur, due to openness as one of the key features of these sites. Social engineering can be misused by attackers concerning on social network with the purpose of gaining ...

Zeitschrift für die gesamte Versicherungswissenschaft, 2000 The article investigates whether compulsory old age provisions are justified from an economic point of view.

The future of social security [PDF]
Journal of Monetary Economics, 2008 We analyze the effect of the projected demographic transition on the political support for social security, and equilibrium outcomes. Embedding a probabilistic-voting setup of electoral competition in the standard OLG model with capital accumulation, we find that intergenerational transfers arise in the absence of altruism, commitment, or trigger ...

Proceedings of the 30th annual ACM SIGACT-SIGOPS symposium on Principles of distributed computing, 2011
We present a cryptographic framework to achieve access control, privacy of social relations, secrecy of resources, and anonymity of users in social networks. The main idea is to use pseudonyms to hide user identities, signatures on pseudonyms to establish social relations, and zero-knowledge proofs on these signatures to demonstrate the existence of ...

The Washington Quarterly, 1999
Belt, Moynihan, and Schieber sketch out middle‐of‐the road proposals that combine a minimum income guarantee—a residue of Social Security—with expanded private savings accounts. This combination, they believe, offers the best compromise between a guarantee against poverty and the benefits of a private system. Nadler disputes the urgency of reform.

Social Security and the Physician
JAMA: The Journal of the American Medical Association, 1965One of the major objectives of most modern "social insurance" programs is universality of coverage; yet self-employed American physicians were able to maintain their independence from the federal Old-Age, Survivors' and Disability Insurance program for almost 30 years.
