agricultural sustainability refers to the ability of a farm to produce food indefinitely, without causing irreversible damage to ecosystem health. the main objective of this study was to formulate a structural model to analyze the effects of ecological, social, and economic factors on sustainable agricultural development in qazvin province of iran. to achieve this aim, a structural model with 4...

Structural equation modeling (SEM) provides a dependable framework for testing differences among groups on latent variables (constructs, factors). The purpose of this article is to illustrate SEM-based testing for group mean differences on latent variables. Related procedures of confirmatory factor analysis and testing for measurement invariance across compared groups are also presented in the ...

We present an approach for the algorithmic computation of causalities in system models that we refer to as causality checking. We base our notion of causality on counterfactual reasoning, in particular using the structural equation model approach by Halpern and Pearl that we recently have extended to reason about computational models. In this paper we present a search-based on-the-fly approach ...

Programmers understand a piece of software by building simplified mental models of it. Aspects of these models lend themselves naturally to formalization – e.g., structural relationships can be partly captured by module dependency graphs. Automated support for generating and analyzing such structural models has proven useful. For event-driven systems, behavioral models, which capture temporal a...

This study develops and tests a research model that investigates work engagement as a mediator of the e¤ects of coworker and supervisor support on career satisfaction, service recovery performance, job performance, and creative performance. Data were obtained from frontline hotel employees with a time lag of one month and their immediate supervisors in Cameroon. The relationships were tested us...

Ecological systems are commonly studied by very concrete conventional models or very abstract random matrix models. Here we review and extend the approach of generalized structural kinetic modeling, that offers an intermediate way between these extremes. Generalized models describe systems with a specific structure, but do not restrict the processes in the model to specific functional forms. Th...

Advancements in communication technologies continue to support the development of geographically-distributed teams. Yet as this practice grows, managers and staff remain concerned about the impact of working physically away from each other. This study theorizes social capital as the primary mechanism by which the level of distribution of individuals in teams and the use of communication technol...

Online vendors expand significant efforts in attracting consumers to their websites. However, once a consumer lands on a vendor’s website, a more challenging task is to convince her/him to actually transact with the website by purchasing products. This research-in-progress study draws on the elaboration-likelihood model (ELM) to develop a theoretical model for the impacts of different persuasio...
