Addiction to cocaine is commonly preceded by experiences with legal or decriminalized drugs, such as alcohol, nicotine, and marijuana. The biological mechanisms which these gateway drugs contribute addiction are only beginning be understood. We report that in the rat, prior alcohol consumption results enhanced addiction-like behavior cocaine, including continued use despite aversive consequences. Conversely, has no effect on preference. Long-term, but not short-term, promotes...
Non-suicidal self-injury (NSSI) is commonly seen in adolescents with depression and a high-risk factor leading to suicide. The psychological mechanisms underlying NSSI are still unclear. purpose of this study was explore the differences personality traits, defensive styles, borderline symptoms among first-episode youth patients compared without healthy populations.The current recruited 188 participants, including 64 NSSI, 60 control subjects. Eysenck Personality Questionnaire, Defense Style...
ABSTRACT We examine the evolution of accounting regulation by linking disclosure policies and investments in a dynamic voting model. The are outcome entrepreneurs, whose preferences influenced their investments. turn endogenously determined current future policies. Absent external influences, regimes stable. A regime high (low) quality strong (weak) economy coexist reinforce each other. However, regulatory interventions can result changes changing entrepreneurs’ expectations, even without...
Optical imaging has the potential to play a major role in breast cancer screening and diagnosis due its ability image characteristics such as angiogenesis hypoxia. A promising approach evaluate quantify these is perform dynamic studies which one monitors hemodynamic response an external stimulus, valsalva maneuver. It been shown that stimuli shows MARKED differences between cancerous healthy tissues. The fast rates large range of digital devices makes them ideal for this type studies. Here...
Geographic price discrimination is generally considered beneficial to firm profitability. Firms can extract higher rents by varying prices across markets match consumers’ preferences. This paper empirically demonstrates, however, that a may instead prefer national pricing policy fixes geographic markets, foregoing the opportunity customize prices. Under appropriate conditions, helps avoid intense local competition due targeted I examine choice of versus under multimarket retail chain using...
We describe a new dynamic optical tomography system that is, unlike currently available analog instrumentation, based on digital data-acquisition and filtering techniques. At the heart of this continuous wave instrument is signal processor (DSP) collects, collates, processes, filters digitized data set. A lock-in filter has been designed for particular application maximizes measurement fidelity. The synchronously-timed processes are controlled by complex programmable logic device (CPLD) also...
We present the design of an optical breast imaging system, which is, unlike currently available analog instrumentation, based on digital conversion, processing, and filtering techniques. The system consists 128 silicon photodiode detectors, 64 excitation points, 4 near-infrared laser diodes. provide detailed insight into signal conditioning, timing light delivery to achieve robust dynamic imaging.
This paper shows that higher transparency in equity markets increases firms’ real investment productive activities, but may also result capital rationing by investors. When multiple firms compete for and an investor allocates on the basis of disclosures, a disclosure tournament results increase their actions enhance outcomes. We show such can over-investment investors limit reducing amount they make available to firms. Consequently, reduce access capital.
