Causal analysis

This dissertation is composed of two parts, an integrative essay and a set of published papers. The essay and the collection of papers are placed in the context of development and application of time series econometric models in a temporal-axis from 1970s through 2005, with particular focus in the Marketing discipline. The main aim of the integrative essay is on modelling the effects of marketing actions on performance variables, such as sales and market share in competitive markets.

The purpose of the thesis "An empirical analysis of firm innovation capability and performance of Indonesian ICT SMEs" is to explore the antecedents of innovation capability and firm performance of ICT SMEs within clusters in Jakarta and Bandung in Indonesia. A causal model was proposed and tested by using Partial Least Squares (PLS-SEM). Findings reveal that intellectual capital is a major contributor of innovation capability. Surprisingly, being spatially close in a specific location does not trigger firms to have innovation capability.

Mitochondrial DNA (mtDNA) deletion mutations accumulate with age in tissues of a variety of species. Although the relatively low calculated abundance of these deletion mutations in whole tissue homogenates led some investigators to suggest that these mutations do not have any physiological impact, their focal and segmental accumulation suggests that they can, and do, accumulate to levels sufficient to affect the metabolism of a tissue.

ESSAYS ON THE RELATIONSHIPS BETWEEN FOREIGN DIRECT IN VESTMENT, INTERNATIONAL TRADE, AND EXCHANGE RATE VOLATILITY My analysis of parental choices focuses on the possibility that parents may choose schools partly on the basis of the peer group offered. Although existing research does not conclusively establish the causal contribution of peer group characteristics to student outcomes (see, e.g., Coleman et al.

EDUCATION AND ECONOMIC GROWTH; A CAUSAL ANALYSIS It similarly seems unlikely that parents have zero concern for peer group. In the presence of direct or indirect peer effects on student learning, parents would be irrational to ignore peer group in their evaluations of schools, and anecdotal evidence suggests that they do not do so.

A procedure has been developed for the isolation of cell walls from the hyphae of the causal agent for barley leaf scald,Rhynchosporium secalis (Oudem) J.J. Davis. Based primarily on monosaccharide linkage analysis, but also on the limited use of linkage-specific glucan hydrolases and solvent fractionation, the walls consist predominantly of (1,3⁄1,6)-b-d-glucans

This is the second in a series of three papers in which we initiate the study of very rough solutions to the initial value problem for the Einstein vacuum equations expressed relative to wave coordinates. By very rough we mean solutions which cannot be constructed by the classical techniques of energy estimates and Sobolev inequalities. In this paper we develop the geometric analysis of the Eikonal equation for microlocalized rough Einstein metrics. This is a crucial step in the derivation of the decay estimates needed in the first paper. ...
