Models are presented in which the distribution of crossovers at a four-four-strand stage of meiosis results from a renewal process. Probability distributions are obtained for the number of crossover events on a meiotic bivalent and for the number of exchange points in random meiotic products. These distributions are found to fit the observed distribution of these variables reasonably well. Usin...

Tendon transfer techniques in the foot and ankle are used for tendon ruptures, deformities, and instabilities. This fresh cadaver study compares the tendon fixation strength in 10 paired specimens by performing a tendon to tendon fixation technique or using 7 x 20-25 mm bioabsorbable interference-fit screw tendon fixation technique. Load at failure of the tendon to tendon fixation method averag...

150) Negative stereotypes about aging can impair older adults’ memory; however, the mechanisms underlying this are unclear. In two experiments we tested competing predictions derived from two theoretical accounts: executive control interference and regulatory fit. Older adults completed a working memory test either under stereotype threat about their memory or not. Monetary incentives were mani...

Negative stereotypes about aging can impair older adults' memory via stereotype threat; however, the mechanisms underlying this phenomenon are unclear. In two experiments, we tested competing predictions derived from two theoretical accounts of stereotype threat: executive-control interference and regulatory fit. Older adults completed a working memory test either under stereotype threat about ...

OBJECTIVES The present study was designed to investigate the causal relationships between (time- and strain-based) work-home interference and employee health. The effort-recovery theory provided the theoretical basis for this study. METHODS Two-phase longitudinal data (with a 1-year time lag) were gathered from 730 Dutch police officers to test the following hypotheses with structural equatio...

The data reported by Baddeley and Scott (1971) is usually interpreted as showing forgetting in short-term memory in the absence of interference. Given the absence of interference, the cause must be decay. SIMPLE (Brown, Neath, & Chater, 2007), a local distinctiveness model of memory, was able to fit the data quite well with no difference in the parameters for the 3, 5, and 7 item lists (R = 0.9...

Cementless total knee arthroplasty (TKA) implants rely on interference fit to achieve initial stability. However, the optimal is unknown. This study investigates effect of using different stability tibial TKA implants. Experiments were performed human cadaveric tibias a low 350 μm clinically established cementless porous-coated implant and high 700 μm. The Orthoload peak loads gait squat applie...
