We present a new multivariate technique for testing the significance of individual terms in a multifactorial analysis-of-variance model for multispecies response variables. The technique will allow researchers to base analyses on measures of association (distance measures) that are ecologically relevant. In addition, unlike other distance-based hypothesis-testing techniques, this method allows ...

This study aimed to investigate the utility of the responses of the two child dummies (P1.5 and P3) that are placed in the rear seat, in identical forwardfacing child restraints during frontal Australian NCAP (ANCAP) tests. Dynamic responses of the two child dummies, vehicle crash parameters, and frontal dummy responses were extracted from the ANCAP report database for 35 frontal crash tests. L...

Nested iteration is an important technique for query evaluation. It is the default way of executing nested subqueries in SQL. Although decorrelation often results in cheaper non-nested plans, decorrelation is not always applicable for nested subqueries. Nested iteration, if implemented properly, can also win over decorrelation for several classes of queries. Decorrelation is also hard to apply ...

OBJECTIVE To determine whether the occurrence of "never events" after major surgical procedures is affected by patient and disease characteristics and by the type of operation performed. DESIGN Epidemiological analysis. INTERVENTIONS Derivation and assessment of predictive equations for postoperative infectious events and decubitus ulcers using Healthcare Cost and Utilization Project Nation...

Ordered categorial predictors are a common case in regression modeling. In contrast to the case of ordinal response variables, ordinal predictors have been largely neglected in the literature. In this article penalized regression techniques are proposed. Based on dummy coding two types of penalization are explicitly developed; the first imposes a difference penalty, the second is a ridge type r...

In a strictly controlled clinical situation, (postoperative sickness) where variables were reduced to a minimum, it was possible to demonstrate an effective prophylactic antiemetic action of P6 (Neiguan) acupuncture. Manual and electrical invasive (needling) stimulation of this point were equally effective. Non-invasive stimulation (transcutaneous electrical or pressure) was effective in the ea...

UNLABELLED We conducted a literature review on the effect of breastfeeding and dummy (pacifier) use on sudden infant death syndrome (SIDS). From 4343 abstracts, we identified 35 relevant studies on breastfeeding and SIDS, 27 on dummy use and SIDS and 59 on dummy use versus breastfeeding. CONCLUSION We found ample evidence that both breastfeeding and dummy use reduce the risk of SIDS. There ha...

61] In addition to conventional measurement microphones, dummy heads are more and more used for physical as well as subjective noise evaluation. Within the DIN, a study group (A2 AK8) was formed, analyzing features of commercially available dummy heads. It was found that mainly because of geometrically different shells, different dummy heads produce different sound images. In practical applicat...
