Strategy selection may help explain performance differences between individuals with high working memory capacity (HWMs) and low working memory capacity (LWMs) (Budd, Whitney, & Turley, (Memory & Cognition, 23, 735-748 1995); Cokely, Kelley, & Gilchrist, (Psychonomic Bulletin & Review, 13, 991-997 2006). We compared the independent and spontaneous strategy use of HWMs and LWMs during a category...

In two different contexts, we examined the hypothesis that individual differences in working memory (WM) capacity are related to the tendency to infer complex, ordinal relationships between numerical symbols. In Experiment 1, we assessed whether this tendency arises in a learning context that involves mapping novel symbols to quantities by training adult participants to associate dot-quantities...

We examined the relation between pressureinduced performance decrements, or ‘‘choking under pressure,’’ in mathematical problem solving and individual differences in working memory capacity. In cognitively based academic skills such as math, pressure is thought to harm performance by reducing the working memory capacity available for skill execution. Results demonstrated that only individuals h...

We study a hedge fund style contract in which management fees, incentive fees and a high water mark provision drive a fund manager’s effort and risk choices as well as walkaway decisions by both the fund manager and the investor. We model this relationship and calibrate the model to observed data. The model yields empirical predictions regarding the impact of a fund’s distance from the high wat...

The purpose of this article is to investigate the applications of hydroponic wastewater management systems (HWMS) as wastewater treatment facilities for the Dead Sea vicinity. In addition, it aims at managing the wastewater through generating commercially valuable plants using a proposed HWMS. A commercial hydroponic system was adapted for studying the potential heavy metals removal from primar...

Recent findings (Beilock & Carr, 2005) demonstrate that only individuals with a high working-memory capacity (WMC) “choke under pressure” on math problems with high WM demands. This suggests that performance pressure hinders those people who are the most qualified to succeed because it consumes the WMC they usually rely on to achieve superior performance, and thereby questions the ability of pe...

شرایط افروزش و اشتعال سوخت‌های گداخت هسته‌ای در حضور ناخالص­‌ها، یکی از موارد مهمی است که طراحی قرص‌های سوخت باید مورد توجه قرار گیرد. این مقاله اثر ناخالصی هسته سنگین طلا بر کلیه فرایندهای احتراق پلاسمای غیرتعادلی دوتریم- تریتیم مدل چهار دمایی آن شکل تابع توزیع انرژی رفتار فوتون‌ها تأثیر می‌گذارد بررسی گرفته است. مطالعه شامل اثرات منفی سوخت، طول زمان تشکیل لکه داغ نتایج محاسبات عددی به­ دست آم...
