E-business, organizational innovation and firm performance in manufacturing SMEs: an empirical study in Spain

Abstract: This paper extends previous studies on the organizational impact of Internet technologies by analyzing factors affecting e-business use and its effect on organizational innovation in manufacturing Small and Medium-Size Enterprises (SMEs). In addition, the mediating effect of organizational innovation on the relationship between e-business and firm performance is analyzed. Grounded in the Technology-Organization-Environment (TOE) theory and the Knowledge-Based View (KBV), this paper develops an integrative research model which analyzes those relations using partial least squares (PLS) structural equation modeling on a dataset of 175 Spanish manufacturing SMEs. Results suggest that e-business use emerges from technological and internal organizational resources rather than from external pressure. In addition, results show that e-business use contributes positively to firm performance through organizational innovation.

Analyzing the determinants of firm§s absorptive capacity: beyond R&D

Abstract: This article proposes a new model for analyzing the determinants of absorptive capacity in companies. We suggest that absorptive capacity is determined not only by research and development activities, but also by a set of internal factors, which we group into three basic categories: organizational knowledge, formalization, and social integration mechanisms. In addition, we suggest that these factors may influence all components of the firm's absorptive capacity, and that the influence can be positive or negative depending on the applicability of the knowledge being absorbed. This paper thus advances the understanding of absorptive capacity by exploring a largely ignored aspect in the literature: the role of knowledge attributes. We show how the model can be operationalized and empirically tested and provide preliminary evidence supporting most of the propositions in the analytical model.

Multifunctional, defect-engineered metal-organic frameworks with ruthenium centers: sorption and catalytic properties.

Abstract: A mixed-linker solid-solution approach was employed to modify the metal sites and introduce structural defects into the mixed-valence Ru(II/III) structural analogue of the well-known MOF family [M3(II,II)(btc)2] (M=Cu, Mo, Cr, Ni, Zn; btc=benzene-1,3,5-tricarboxylate), with partly missing carboxylate ligators at the Ru2 paddle-wheels. Incorporation of pyridine-3,5-dicarboxylate (pydc), which is the same size as btc but carries lower charge, as a second, defective linker has led to the mixed-linker isoreticular derivatives of Ru-MOF, which display characteristics unlike those of the defect-free framework. Along with the creation of additional coordinatively unsaturated sites, the incorporation of pydc induces the partial reduction of ruthenium. Accordingly, the modified Ru sites are responsible for the activity of the "defective" variants in the dissociative chemisorption of CO2, the enhanced performance in CO sorption, the formation of hydride species, and the catalytic hydrogenation of olefins.
