Latent Semantic Indexing (LSI), a variant of classical Vector Space Model (VSM), is an Information Retrieval (IR) model that attempts to capture the latent semantic relationship between the data items. Mathematical lattices, under the framework of Formal Concept Analysis (FCA), represent conceptual hierarchies in data and retrieve the information. However, both LSI and FCA use the data represen...

Volatile substance misuse (VSM) among Israeli youth has been identified as widespread and growing. Using data from the 2009 National School Survey of 12-18 year olds (N = 7,166), this study describes VSM prevalence among Jews and Arabs, examining relationships between past-month VSM and sociodemographic, behavioral, psychological, and interpersonal characteristics. Past-month VSM, reported by 7...

Structured Abstract: Purpose: To design a Viable Model for scholarly communication system. Approach: Stafford Beer's Viable System Model (VSM) is an exceptionally insightful analysis tool which has been applied in different fields. This article illustrates the usefulness of Beer's model as a tool for anticipating, planning for, and implementing large scale development in scientific communicatio...

Rho-kinase, an effector of Rho GTPase, increases the contractility of vascular smooth muscle by phosphorylating myosin light chain (MLC) and by inactivating MLC phosphatase. A wide variety of extracellular stimuli activate RhoA via G protein-coupled receptors. In the present study, we demonstrate a novel cell-cell interaction-mediated Rho activation signaling pathway in vascular smooth muscle c...

Although glucocorticoid (GC)-induced hypertension has commonly been attributed to promiscuous activation of the mineralocorticoid receptor by cortisol, thereby promoting excess reabsorption of sodium and water, numerous lines of evidence indicate that this is not the only or perhaps even the primary mechanism. GC induce a number of effects on vascular smooth muscle (VSM) in vitro that may be pe...

Elevated blood pressure imposes increased mechanical stress on the vascular wall, and mechanical strain is a mitogenic stimulus for vascular smooth muscle (VSM) cells. The role of mechanical forces in regulating the production of noncellular material by VSM cells for VSM cells of human origin remains undefined. We thus investigated the effects of chronic cyclical mechanical strain on extracellu...

The Viable System Model (VSM) is not a new idea. Created by Stafford Beer over twenty years ago, it has been used extensively as a conceptual tool for understanding organizations, redesigning them (where appropriate) and supporting the management of change. Despite its successful application within numerous private and public sector organizations, however, the VSM is not yet widely known among ...

We apply the viable system model (VSM) in the management control system (MCS) area in order to address the multifarious relationships between enterprise resource planning (ERP) systems and budgeting through the introduction of five research criteria: ERP system, budgeting, informal control, organizational hierarchy and the relationships among them. The research question discussed is: How can we...
