This paper proposes a model of meta-reflection and in-depth analysis of the knowledge creation process (KCP). The authors focus on observation of the KCP in research on creative design. The new method of meta-reflection is applied both to reflection on ‘research about design creativity’ and object of research—‘design creativity’. One result of the applied method of meta-reflection was that the ...
The therapeutic effect of ME1228, a new parenteral cephalosporin, was compared with that of broad-spectrum cephems in normal and neutropenic mice infected with various species of bacteria. The results showed that ME1228 was more active than were the other cephems against infections with various pathogens.
This research applies ideas from argumentation theory in the context of semantic wikis, aiming to provide support for structured-large scale argumentation between human agents. The implemented prototype is exemplified by modelling the MMR vaccine controversy.
We propose to automatically summarize student responses to reflection prompts and introduce a novel summarization algorithm that differs from traditional methods in several ways. First, since the linguistic units of student inputs range from single words to multiple sentences, our summaries are created from extracted phrases rather than from sentences. Second, the phrase summarization algorithm...
Many Intelligent Tutoring Systems (ITSs) have started to incorporate game-based components in an attempt to improve student engagement during system interactions. iSTART-ME is a new game-based learning environment that was developed on top of an existing ITS (iSTART). Initial investigations focused on individual, isolated components. However, to increase ecological validity, the current study w...
The n-hexane (HE), dichloromethane (DC), methanol (ME), ethanol 70% (ET), and methanol with Soxlhet apparatus (MS) extracts of Stachys lavandulifolia aerial parts were screened for their potential tyrosinase, acetylcholinesterase (AChE) and butyrylcholinesterase (BChE) inhibitory activity. ET and MS inhibited tyrosinase with IC50 values of 33.4 and 42.8 μg/mL, respectively. The phytochemical in...
β-Glucosidase (EC 3.2.1.21) is a prominent member of the GH1 family of glycoside hydrolases. The properties of this β-glucosidase appear to include resistance to temperature, urea, and iodoacetamide, and it is activated by 2-ME, similar to other members. β-Glucosidase from chayote (Sechium edule) was purified by ionic-interchange chromatography and molecular exclusion chromatography. Peptides d...
