This article considers the social and psychological functions that norm-based thinking and behavior provide for the individual and the collectivity. We differentiate between two types of reference groups that provide norms: peer groups versus aspirational groups. We integrate functionalist accounts by distinguishing the functions served by the norms of different reference groups, different degrees of norm moralization, and different directions of responses to norm activation.

Of all publications on success in sales appearing in this century and many decades previously, The Challenger Sale has perhaps generated more discussion and controversy among sales leaders, strategic account program directors and strategic account managers than any other. But does this widely read and discussed volume actually represent the breakthrough that Neil Rackham suggests, or is it just an interesting examination of sales that serves mainly as an infomercial for the Corporate Executive Board (sponsor of the research) and its affiliates?

We introduce a regression-based nested Monte Carlo simulation method for the estimation of financial risk. An outer simulation level is used to generate financial risk factors and an inner simulation level is used to price securities and compute portfolio losses given risk factor outcomes. The mean squared error (MSE) of standard nested simulation converges at the rate, where measures computational effort. The proposed regression method combines information from different risk factor realizations to provide a better estimate of the portfolio loss function.

We propose that an individual's regulatory focus moderates the significant role social network density — the degree of interconnectedness among a person's social contacts — plays in shaping life satisfaction. Evidence from Study 1 indicates that participants with high prevention effectiveness reported higher life satisfaction when they were embedded in a high-density network, whereas participants with low promotion effectiveness reported lower life satisfaction when they were embedded in a low-density network.
