TL;DR: In this article, the authors investigate publicly available index ratings to assess strategies for and qualitative measurement of the sustainable development and innovation performance of eight top-ranked international companies and find that the strategies of the identified companies correspond well to our typology and allow suggestions of where efforts for corporate sustainability and entrepreneurship could be reinforced to gain or maintain a benchmark positioa.
Abstract: The field of sustainable corporate entrepreneurship is in a nascent stage. By developing a position matrix of companies with respect to their corporate entrepreneurship and sustainability performance, we make conceptual contributions to an integrated perspective on elements supporting a sustainable corporate entrepreneurship process. We propose that such a process without evolving corporate sustainability is misleading. Methodologically, we investigate publicly available index ratings to assess strategies for and qualitative measurement of the sustainable development and innovation performance of eight top-ranked international companies. Findings show that the strategies of the identified companies correspond well to our typology and allow suggestions of where efforts for corporate sustainability and/or entrepreneurship could be reinforced to gain or maintain a benchmark positioa. The article will clarify underlying elements of, and help to advance strategies for the implementation of, a sustainable corporate entrepreneurship process.

TL;DR: In this article, the electrical performance of micromachined piezoelectric cantilevers having different designs is investigated in liquid environment, thus making most beneficially use of their self-actuated and self-sensing capability.
Abstract: In this work the electrical performance of micromachined piezoelectric cantilevers having different designs is investigated in liquid environment, thus making most beneficially use of their self-actuated and self-sensing capability. The impact of parasitic effects originating from e.g. the electrical feedlines, on the sensing characteristics is discussed. The focus is set on in-plane bending modes excited in a large viscosity range from 1.09 cP to 238.82 cP and the corresponding influence on the conductance peak, which is important especially for liquid monitoring purposes. Furthermore, an analytical model for the dynamic admittance and the conductance peak is presented and compared to the measurements. Based on these results design guidelines for optimizing the performance of piezoelectric in-plane resonators are presented.

TL;DR: The detection of force-induced displacements within compact MEMS (microelectromechanical system) devices can be used to measure electric field strength without significant field distortion.
Abstract: Small-scale and distortion-free measurement of electric fields is crucial for applications such as surveying atmospheric electrostatic fields, lightning research and safeguarding areas close to high-voltage power lines. A variety of measurement systems exist, the most common of which are field mills, which work by picking up the differential voltage of the measurement electrodes while periodically shielding them with a grounded electrode. However, all current approaches are bulky, suffer from a strong temperature dependency or severely distort the electric field, and thus require a well-defined surrounding and complex calibration procedures. Here we show that microelectromechanical system (MEMS) devices can be used to measure electric field strength without significant field distortion. The purely passive MEMS devices exploit the effect of electrostatic induction, which is used to generate internal forces that are converted into an optically tracked mechanical displacement of a spring-suspended seismic mass. The devices exhibit resolutions on the order of 100 V m−1 Hz−1/2 with a measurement range of up to tens of kilovolts per metre in the quasi-static regime ≲300 Hz). We also show that it should be possible to achieve resolutions of around 1 V m−1 Hz−1/2 by fine-tuning the sensor embodiment. These MEMS devices are compact and could be mass produced easily for wide application. The detection of force-induced displacements within compact MEMS (microelectromechanical system) devices can be used to measure electric field strength without significant field distortion.

TL;DR: This paper implemented a number of methods within the MediaWiki system, where social rewarding criteria are satisfied by generating a ranking of most active members, which aims to meet the needs of users.
Abstract: Online communities have something in common: their success rise and fall with the participation rate of active users. In this paper we focus on social rewarding mechanisms that generate benefits for users in order to achieve a higher contribution rate in a wiki system. In an online community, social rewarding is in the majority of cases based on accentuation of the most active members. As money cannot be used as a motivating factor others like status, power, acceptance, and glory have to be employed. We explain different social rewarding mechanisms which aim to meet these needs of users. Furthermore, we implemented a number of methods within the MediaWiki system, where social rewarding criteria are satisfied by generating a ranking of most active members.

TL;DR: Fractionated plasma separation and adsorption (FPSA) is a nonbiologic detoxification system for the treatment of liver failure as discussed by the authors, which is a promising technique to improve clearance of protein-bound uremic retention solutes.
Abstract: Removal of protein-bound uremic retention solutes, including p-cresol, by peritoneal dialysis and hemodialysis (HD) is limited. p-Cresol, mainly circulating as sulfate conjugate (p-cresyl sulfate [PCS]), is independently associated with mortality. Fractionated plasma separation and adsorption (FPSA) is a nonbiologic detoxification system for the treatment of liver failure. The FPSA clearance of uremic retention solutes is unknown. We studied PCS clearance by FPSA, using the Prometheus system. The neutral resin adsorbent and the anion exchange adsorbent bind PCS in vitro (reduction ratios [RRs] 37 and 70%). Ex vivo, the adsorbent mass removal (MR) (median 47.5 mg) contributes more than half to total MR (median 89.6 mg). In vivo, PCS RR during FPSA (50%) exceeded the RR during high flux HD (30%). We halted the study after four inclusions due to repeated thrombosis of the arterio-venous conduit. In conclusion, FPSA is a promising technique to improve clearance of protein-bound uremic retention solutes.
