We consider the related notions of two-prover and of relativistic commitment schemes. In recent work, Lunghi et al. proposed a new relativistic commitment scheme with a multi-round sustain phase that keeps the binding property alive as long as the sustain phase is running. They prove security of their scheme against classical attacks; however, the proven bound on the error parameter is very wea...

Negotiations often take time, thereby delaying the implementation of agreements which are to the mutual advantage of the bargaining partners. If the negotiators are all impatient, then these delayed agreements must be inefficient, as all participants must strictly prefer an immediate agreement on the same terms. The inefficiency of delayed agreements poses an important explanatory question: Why...

This study examined the attitudes of employees working in Indian hotels catering to tourists. It analyzed their perception of training opportunities and the impact of such training on the service provided to guests. An integrated model was developed highlighting the relationship between perceived accessibility to training, perceived support for training, perceived benefits from training, and th...

METHODS An overview is provided on the status of old age psychology and psychiatry as part of the multidisciplinary care delivery system for the elderly in Po...

Low-volume 'sprint' interval training (SIT) stimulates rapid improvements in muscle oxidative capacity that are comparable to levels reached following traditional endurance training (ET) but no study has examined metabolic adaptations during exercise after these different training strategies. We hypothesized that SIT and ET would induce similar adaptations in markers of skeletal muscle carbohyd...

Boston University (BU) has a long history of a strong social mission and commitment to service. In August 2003, BU made an institutional commitment to work with the country of Lesotho to tackle the human capital implications of the HIV/AIDS epidemic. Surrounded by South Africa, and with a population of two million, Lesotho, a stable democracy, suffers the world's third-highest adult HIV prevale...

We present the first universally verifiable voting scheme that can be based on a general assumption (existence of a non-interactive commitment scheme). Our scheme is also the first receipt-free scheme to give “everlasting privacy” for votes: even a computationally unbounded party does not gain any information about individual votes (other than what can be inferred from the

Introduction. Commitment schemes are one of the most fundamental primitives in cryptography. A commitment scheme is a two-party protocol consisting of two phases, the commit and the open phase. The goal of the commitment is to allow the sender to transmit information related to a message m during the commit phase in such a way that the recipient learns nothing about the message (hiding property...
