This study used structural equations modeling and undergraduate student data to examine the effects of reward and threat sensitivities on substance use, along with the extent to which impulsivity explained these effects. Our results suggest that impulsivity may translate inversely related reward and threat sensitivities into substance use, completely mediate the effect between threat sensitivit...

There is broad consensus that printed complex words are identified on the basis of their constituent morphemes. This fact raises the issue of how the word identification system codes for morpheme position, hence allowing it to distinguish between words like overhang and hangover, and to recognize that preheat is a word, whereas heatpre is not. Recent data have shown that suffixes are identified...

BACKGROUND AND AIMS Substance use and risk-taking are common during emerging adulthood, a transitional period when peer influences often increase and family influences decrease. Investigating relationships between social network features and substance use can inform community-based prevention programs. This study investigated whether substance use among emerging adults living in disadvantaged u...

Too often basic research on etiological processes that contribute to substance use outcomes is disconnected from efforts to develop prevention and intervention programming. Substance use on college campuses is an area of concern where translational efforts that bring together basic scientists and prevention/intervention practitioners have potential for high impact. We describe an effort at a la...

In many problems in molecular and solid state structures one seeks to determine the energy-minimizing decoration of sites with different atom types. In other problems, one is interested in finding a decoration with a target physical property (e.g. alloy band gap) within a certain range. In both cases, the sheer size of the configurational space can be horrendous. We present two approaches which...

abstract reliefs are one the most important archaeological evidences to elucidate vague facts of previous cultures. this tradition has a long history in iran`s culture that revitalized in qajarians in different parts of iran, there are forty seven reliefs with engraved decoration in stone collection of taq-i-bustan, too. so far, no report or newsletter about qajarian reliefs in taq-i-bustan col...

BACKGROUND A precise experimental identification of transcription factor binding motifs (TFBMs), accurate to a single base pair, is time-consuming and diffcult. For several databases, TFBM annotations are extracted from the literature and stored 5' --> 3' relative to the target gene. Mixing the two possible orientations of a motif results in poor information content of subsequently computed pos...
