Composite SelfConcordant Minimization ∗
"... We propose a variable metric framework for minimizing the sum of a selfconcordant function and a possibly nonsmooth convex function endowed with a computable proximal operator. We theoretically establish the convergence of our framework without relying on the usual Lipschitz gradient assumption on ..."

Selfconcordance for empirical likelihood
, 2012
"... The usual approach to computing empirical likelihood for the mean uses Newton’s method after eliminating a Lagrange multiplier and replacing the function − log(x) by a quadratic Taylor approximation to the left of 1/n. This paper replaces the quadratic approximation by a quartic. The result is a sel ..."

Scalable sparse covariance estimation via selfconcordance
"... We consider the class of convex minimization problems, composed of a selfconcordant function, such as the log det metric, a convex data fidelity term h(·) and, a regularizing – possibly nonsmooth – function g(·). This type of problems have recently attracted a great deal of interest, mainly due t ..."

1 Running Head: SELFCONCORDANCE Core SelfEvaluations and Job and Life Satisfaction: The Role of SelfConcordance and Goal Attainment
"... The present study tested a model explaining how the core selfevaluations (i.e., positive selfregard) concept is linked to job and life satisfaction. The selfconcordance model, which focuses on motives underlying goal pursuit, was used as an explanatory framework. Data were collected from two samp ..."

samples: (1) 183 university students that included longitudinal measures of goal attainment and life satisfaction; (2) 251 employees where longitudinal measures of goal attainment and job satisfaction were utilized. In both studies, the core selfevaluations concept was positively related to goal selfconcordance
Risk and protective factors for alcohol and other drug problems in adolescence and early adulthood: Implications for substance abuse prevention
 Psychological Bulletin
, 1992
"... The authors suggest that the most promising route to effective strategies for the prevention of adolescent alcohol and other drug problems is through a riskfocused approach. This approach requires the identification of risk factors for drug abuse, identification of methods by which risk factors hav ..."

Global Optimization with Polynomials and the Problem of Moments
 SIAM Journal on Optimization
, 2001
"... We consider the problem of finding the unconstrained global minimum of a realvalued polynomial p(x) : R R, as well as the global minimum of p(x), in a compact set K defined by polynomial inequalities. It is shown that this problem reduces to solving an (often finite) sequence of convex linear mat ..."

We consider the problem of finding the unconstrained global minimum of a realvalued polynomial p(x) : R R, as well as the global minimum of p(x), in a compact set K defined by polynomial inequalities. It is shown that this problem reduces to solving an (often finite) sequence of convex linear matrix inequality (LMI) problems. A notion of KarushKuhnTucker polynomials is introduced in a global optimality condition. Some illustrative examples are provided. Key words. global optimization, theory of moments and positive polynomials, semidefinite programming AMS subject classifications. 90C22, 90C25 PII. S1052623400366802 1.

The Internet presents numerous sources of useful informationtelephone directories, product catalogs, stock quotes, weather forecasts, etc. Recently, many systems have been built that automatically gather and manipulate such information on a user's behalf. However, these resources are usually formatted for use by people (e.g., the relevant content is embedded in HTML pages), so extracting their content is difficult. Wrappers are often used for this purpose. A wrapper is a procedure for extracting a particular resource's content. Unfortunately, handcoding wrappers is tedious. We introduce wrapper induction, a technique for automatically constructing wrappers. Our techniques can be described in terms of three main contributions. First, we pose the problem of wrapper construction as one of inductive learn...
