Stirring-assisted dead-end ultrafiltration for protein and polyphenol recovery from purple sweet potato juices: Filtration behavior investigation and…
2016
The potential of stirring assisted dead-end ultrafiltration (UF) to recover polyphenols from purple sweet potato (PSP) juices was evaluated. For this purpose, the effects of rotation speed (200–600 rpm), transmembrane pressure (TMP) (0.2–0.4 MPa), and membrane molecular weight cut-off (30–100 kDa) were investigated with a lab-scale filtration module. The results showed that the highest protein removal (86%) and polyphenol selectivity (12.2) were both obtained under higher rotation speed (600 rpm). Moreover, filtration flux was more important at 600 rpm due to the anti-fouling effect of shear rate generated by the rotation. The results also revealed that under TMP of 0.4 MPa, the cake resist…
Higher Dead End?
2005
One of the main problems of Finnish higher education researcher training is the lack of any systematic training. It seems, however, that it is not only one of the main problems but also a result of a development related to the structure of funding sources and the status of higher education research as an academic field. In this article I will begin by describing how this situation has developed and what are the current problems. Secondly, I will reflect on the future avenues of higher education research and researcher training, which seem to be approaching a (higher) dead end. The article is based on personal experiences gained as a researcher in several higher education research projects a…
Short-Termism: A Step Forward Toward Long-Term Performance or a Dead End
2018
The debate around short-termism and its effects on the economic life, rather negative than positive, is far from ending, having academics, practitioners, and pundits arguing on this topic. The purpose of this paper is to determine if short-termism is part of the process of creating long-term performance (value) in an organization or it is harmful for harnessing performance, by presenting the definitions of the concept, who are the main promoters of short-termism, opinions of both academics and practitioners, and studies and examples that sustain on the one side the fact that short-termism encourages the manipulation of numbers in order to meet quarterly earnings, by cutting investments from…
