This study examines investor response to three events that help define a federal class action securities lawsuit, specifically, the announcement that names an issuer as a defendant in the lawsuit (at the class action filing date), the disclosure or accounting restatement that ‘corrects’ the information deficiency (at the end of the class period), and the date at which the fraud on the market allegedly begins (at the beginning of the class period).

In the year 2000, a new phase of the dysfunctional power of religion exploded into the modern public space in Nigeria. Some regional states in the north of the country exploited a loophole in the 1999 constitution to declare themselves as sharia states. Debate on the constitutional legality, political, socio-economic and gender implications of this development became complicated by ethnicity and regionalism. (more…)

This article presents a survey of denial of service attacks and the methodsthat have been proposed for defense against these attacks. In this survey, we analyze the designdecisions in the Internet that have created the potential for denial of service attacks. (more…)

Most crash severity studies ignored severity correlations between driver–vehicle units involved in the same crashes. Models without accounting for these within-crash correlations will result in biased estimates in the factor effects. This study developed a Bayesian hierarchical binomial logistic model to identify the significant factors affecting the severity level of driver injury and vehicle damage in traffic crashes at signalized intersections. Crash data in Singapore were employed to calibrate the model. Model fitness assessment and comparison using intra-class correlation coefficient (ICC) and deviance information criterion (DIC) ensured the suitability of introducing the crash-level random effects.

BACKGROUND: Sporotrichosis is a granulomatous fungal infection caused bySporothrix schenckii, which frequently causes cutaneous or lymphocutaneous lesions and rarely hasoral manifestations. (more…)

Data from the National Cytology Proficiency Testing Update show that as ofJanuary 31, 2006, 9% of 12,786 examinees failed the test on the first attempt. For the secondattempt, the failure rate among those who had initially failed remained surprisingly similar, 10%,although common sense would dictate that it should be much higher among those who have alreadyfailed the test once and should have lower professional skills. What is the reason for thisremarkable improvement in performance? (more…)

Abstract The size and composition of the nematode assemblage in soil under faecal patsderived from young cattle treated or untreated with either ivermectin sustained-release boluses, orthe nematophagous fungus Duddingtonia flagrans , were studied in each of three years. Soil samplestaken 4, 6, 8 and 10 weeks after four deposition dates in 1998 showed significant temporal effectsin many taxa and treatment effects in a few genera. (more…)

Abstract Ventricular tachycardia (VT) provokes sudden cardiac death (SCD), which is amajor cause of mortality in developed countries. Implantable cardioverter-defibrillators (ICDs) arean efficient therapy for SCD prevention. In this study we analyze heart rate variability (HRV) indata stored by ICDs. In 29 patients exhibiting VT episodes, (more…)
