A series of vanadium(V) complexes with o-dioxolene (catecholato) ligands and an ancillary ligand, (N-(salicylideneaminato)ethylenediamine) (hensal), were investigated using 51V solid-state magic angle spinning NMR spectroscopy (51V MAS NMR) to assess the local environment of the vanadium(V). The solid-state 51V NMR parameters of vanadium(V) complexes with a related potentially tetradentate anci...

Preoperative uterine artery embolization and cervical evacuation as conservative management of cervical pregnancy has been tried in recent years. However, cervical suturing, vasoconstrictor injection, or cervical ballooning was frequently used as an ancillary measures in those procedures in most of the previous studies.

Treating enterprises as systems is a promising approach, but enterprises depend on a substantial social component. The inherent complexity of social systems introduces epistemic limitations that inhibit our ability to model social systems a...

This paper describes an intelligent decision support system for evaluating state-owned enterprises (SOEs) using DEA models. This decision support system converts numerical data into information that can be used to evaluate state-owned enterprises (SOEs). In this paper, we use DEA models, including CCR, BCC and FDH, to shed new light on the operational efficiency and determinants of stateowned e...

In an unstable environment, enterprises are gradually realizing that there should be major changes in how they deploy their strategic resources to compete in the knowledge economy. In this paper, the role of competitive intelligence in South African manufacturing enterprises is examined. The difference between the industrial and the knowledge economy and the competitive intelligence function in...

Many large enterprises develop their software nowadays in globally distributed settings. By using the option to outsource, the respective enterprises can realize decisive competitive advantages. In order to remain competitive, small and medium-sized enterprises (SMEs) are also forced to follow this trend and to outsource parts of their software development. However, most of the existing studies...

Nowadays, enterprises can gain and sustain a competitive advantage in hypercompetitive environments for only a limited period of time. In order to be able to do that, enterprises must be dynamic. Even though – several authors suggest a positive association between organisational culture and the enterprise’s dynamic – we are still lacking the empirical support for such assertion. Therefore, we e...
