This paper describes the products and processes developed by the Information Systems Development and Management Subprogramme (ISDM) of the Kruger National Park Rivers Research Programme (KNPRRP) Phase II. The goals of the KNPRRP are to: • inform researchers, system managers and stakeholders about the water quality and quantity requirements to sustain the natural environment of rivers which flow...

For the OLS estimators in a classical linear model to have average partial effects interpretation, one usually imposes the so-called “strict exogeneity”condition. In practice, testing strict exogeneity condition can be done by omnibus nonparametric test. However, there are cases where strict exogeneity condition fails but the average partial effects interpretation of OLS estimator still survive...

E. Abel andM. Kruger (2005) reported that the median life expectancy of Major League Baseball players after election to the Baseball Hall of Fame is 5 years shorter than that of players of the same age who are not elected to the Hall of Fame. This conclusion is surprising because there is no compelling explanation for such a dramatic reduction in life expectancy. However, the data used in that ...

introduction: semen parameters and specially sperm morphology is used for the assessment of semen sample and for the prediction of the fertilization. however there is semen samples with normal sperm morphology but with hidden sperm chromatin anomalies. since sperm morphology and chromatin anomalies reduce the fertilization rat independently, the purpose of this study is to consider the relation...

For—according to the lore—any attempt at pullingoff this featwill reduce themtomaterial implicationand that is decidedlynot agoodwayof assigning truth-conditions to ordinary indicative if s. That is too bad since it seems like they are bounded from above by strict implication (they are true when their antecedents straight out imply their consequents), are bounded from below by material implicat...

The nuclear envelope (NE) is a fundamental structure of the nucleus and plays an important role in nuclear morphology through the strict regulation of NE protein function. Beyond its physical barrier function between nucleoplasm and cytoplasm, recent studies of the plant NE have provided novel insights into basic aspects of nuclear morphology as well as cellular organization. In this review, we...
