Relationship between employee involvement and lean manufacturing and its effect on performance in a rigid continuous process industry

Relationship between employee involvement and lean manufacturing and its effect on performance in a rigid continuous process industry DOI: 10.1080/00207543.2014.975852 Juan A. Marin-Garciaa* & Tomas Bonaviab Received: 1 Aug 2013 Accepted: 30 Sep 2014 Published online: 04 Nov 2014 This research aims to empirically test the effect of employee involvement on lean manufacturing (LM), and the effect of LM on production outcomes. Employee involvement is operationalised through four related variables: empowerment, training, contingent remuneration and communication. The effects are tested by recording management perceptions in a different industrial sector from those usually studied in previous research ceramic manufacturers, a highly competitive and internationally successful sector. We obtained data from 101 ceramic tile plants (64% of response rate) in the Valencia region of Spain. This approach is developed using a statistical method called partial least squares. All paths are significant except for contingent remuneration; specifically, relationships were found between empowerment, training, communication and LM, and between LM and performance.This paper has been written with financial support from the Project "Path Dependence and decision-making for selecting LM tools and practices" (PAID-06-12-SP20120717) of the Universitat Politecnica de Valencia.Marín García, JA.; Bonavía Martín, T.

Simvastatin attenuates trinitrobenzene sulfonic acid-induced colitis, but not oxazalone-induced colitis.

PURPOSE: To determine whether simvastatin is able to inhibit inflammation in trinitrobenzene sulfonic acid (TNBS)-induced or oxazalone (OXA)-induced colitis. RESULTS: In the prophylactic protocol, simvastatin dose-dependently suppressed the decrease in body weight and inflammatory grade of TNBS-treated mice. In contrast, in the therapeutic protocol, no significant difference in body weight reduction was observed between simvastatin-treated and control mice. IFN-gamma release from LP cells was significantly suppressed in mice receiving high-dose simvastatin in the prophylactic protocol. In contrast to TNBS colitis, even high-dose prophylactic simvastatin had no suppressive effects on either weight reduction or the inflammatory grade in OXA colitis. CONCLUSION: Our results indicate that simvastatin negatively regulates inflammation in TNBS-induced colitis, but not in OXA-induced colitis. In TNBS-induced colitis, simvastatin suppressed the Th1-polarized immune response. Our findings suggest that simvastatin has potential effects as a therapeutic agent in human inflammatory bowel disease, particularly Crohn\u27s disease
