Research on the reciprocal influence of spatial thinking and GIScience training is limited (Wakabayashi & Ishikawa, 2011). In the current project, we examine improvement in spatial navigation in undergraduates enrolled in GIS classes over the course of a semester. Students enrolled in strategic communications (SC), a low-spatial content class, were used as a control group. Fifty students were t...

Abstract Robin Hendry has presented an account of two equally valid ways understanding the nature chemical bonding, consisting what terms structural and energetic views respectively. In response, Weisberg issued a “challenge to view”, thus implying that view is more correct conceptions. doing so identifies delocalization electrons as one robust feature underlies increasingly accurate quantum me...

In this paper, we propose two new methods to estimate the dimensionreduction directions of the central subspace (CS) by constructing a regression model such that the directions are all captured in the regression mean. Compared with the inverse regression estimation methods (e.g. Li, 1991, 1992; Cook and Weisberg, 1991), the new methods require no strong assumptions on the design of covariates o...

Recent findings have demonstrated that explanations provided by scientists are deemed better when they are supplemented with scientific evidence even when that evidence is irrelevant (Weisberg, Keil, Goodstein, Rawson, & Gray, 2008). In the present study, participants were asked to solve a syllogistic reasoning task. Two kinds of irrelevant explanations were provided: mechanistic explanations (...

Despite overwhelming scientific consensus, popular opinions regarding evolution are starkly divided. In the USA, for example, nearly one in three adults espouse a literal and recent divine creation account of human origins. Plausibly, resistance to scientific conclusions regarding the origins of species-like much resistance to other scientific conclusions (Bloom & Weisberg, 2007)-gains support ...

The understanding about influence measures is not new and certainly dates back to the first effort to detect anomalous observations that exert an unduly large impact on the regression output. The earliest development in this context that we have been able to locate is by Cook (1977). In recently the phrase ‘influence measures’ has glimpsed a great surge of research interests. In this paper the ...

3 79 A8f A*. Blockade of GABAergic inhibition increases receptive field (RF) size of most somatosensory cortex (SI) and some ventrobasal thalamus (VB) neurons. To determine if GABA-mediated inhibition controls RF size of cuneate neurons, GAB A and GAB A receptor antagonists were applied by iontophoresis. Glutamate was applied to determine if firing frequency affected RF size. Twenty-nine of thi...

Coagulation disorders concern a deficiency of the body’s functional ability to regulate blood clotting (Peyvandi and Mannucci, 1999). Disorders in thisarea, which may be genetic or acquired, will result in hemostasis-related problems, including different clinical syndromes from easy bleeding or bruising (so-called “hemophilia”) to inappropriate thrombosis (so-called “thrombophilia”; Weisberg, 1...

This paper considers the use of the freeware package XLISP-STAT (Tierney, 1990) and the add-on package ARC (Cook and Weisberg, 1999) to explore multilevel data structures before more formal modelling. Exploratory data analysis (Chatfield, 1988) is regarded as an essential before further analysis. XLISPSTAT is highly interactive and with ARC can be used to investigate multilevel structures graph...
