This article introduces tools for analyzing path diagrams using graphical methods, which are better known in epidemiology than among researchers in the behavioral sciences, who would be more familiar with traditional structural equation modeling (SEM). We describe graphical tools that locate covariates for adjustment and instrumental variables, both of which can be used to identify and estimate...

By introducing environmental mediator, for avoiding randomness in selecting indicators and subjectivity in deciding interaction path coefficients to reveal interaction mechanism among forest industry, ecology and environmental capacity, structural Pressure–State–Impact–Response (PSIR) and quantitative Structural Equation Modeling (SEM) are utilized with data on thirty–one provinces of China. We...

1. Ecologists and evolutionary biologists are relying on an increasingly sophisticated set of statistical tools to describe complex natural systems. One such tool that has gained increasing traction in the life sciences is structural equation modeling (SEM), a variant of path analysis that resolves complex multivariate relationships among a suite of interrelated variables. 2. SEM has historical...

This paper aims to develop a research model to examine the mechanisms by which business analytics capabilities in healthcare units are shown to indirectly influence decision-making effectiveness through a mediating role of absorptive capacity. We employed a survey method to collect primary data from Taiwan's hospitals. Structural equation modeling (SEM) was used for path analysis. This study co...

e nergy consumption has increased significantly in iran during the recent decades. in this study, an inter-industrial model has been improved to investigate the sources of the changes in the energy consumption of the country. the input-output tables of iran for the years 1988 and 2001 have been employed as the database of the model. the innovation of this research allows the researchers to stud...

integration and coherence within a city’s physical structure have become an issue for towns and cities as theyrapidly expand, incorporate new elements, and undergo incessant changes. at present, we are facing an extensive accumulation of signs and traits in modern urban patterns; many unaccustomed to and incongruous are affecting the socio-cultural and physical characters of cities. here, we wi...

In this paper, we present a rigorous methodology for quantifying the anonymity provided by Tor against a variety of structural attacks, i.e., adversaries that corrupt Tor nodes and thereby perform eavesdropping attacks to deanonymize Tor users. First, we provide an algorithmic approach for computing the anonymity impact of such structural attacks against Tor. The algorithm is parametric in the ...

. in order to study the variation for seed yield and its components, 200 accessions of alfalfa (medicago sativa l.) were sown as drilled plots, using alpha designs/unreplicated with two repeated entries with in all of 10 blocks under dry land farming system in kabodarahang research station, hamadan, iran, during 2010 to 2011. data were analyzed for descriptive statistics, correlation, regressio...

In this paper, we present a rigorous methodology for quantifying the anonymity provided by Tor against a variety of structural attacks, i.e., adversaries that compromise Tor nodes and thereby perform eavesdropping attacks to deanonymize Tor users. First, we provide an algorithmic approach for computing the anonymity impact of such structural attacks against Tor. The algorithm is parametric in t...

neighborhood attachment is closely related to concrete and abstract conceptions that set the scene for a variety of interactions among the residents. it is on the basis of social-physical location which happens over time. neighborhood attachment also enhances the possibility of residents’ social participation in urban neighborhoods and has a bilateral relationship with residents’ satisfaction. ...
