B501 promoted the production of artemisinin in Artemisia annua L. hairy root culture. When hairy roots of 22-day-old cultures (later growth phase) were exposed to the elicitor (20 mg/L) for 4 d, the maximum content of artemisinin reached 1.15 mg/g, a 64.29% increment over the control. The electron X-ray microanalysis disclosed the rapid accumulation of Ca 2+ in the elicited cortical cells of hairy root. The electronic microscope observation revealed the high electron density area in vacuole of elicited cells. During the first day of elicitation the peroxidase activity of hairy roots was improved sharply. Some cellular morphological changes including cell shrinkage, condensation of cytoplasm and nuclear fragmentation, coincident with the appearance of DNA ladders, were observed after the third day of elicitation. It was suggested that the oligosaccharide elicitor triggered the programmed cell death, which may provide the substance or chemical signal for artemisinin biosynthesis. 展开更多

Confucianism (especially its teaching theory) is the core of Chinese traditional culture with Confucius as its representative. It has played an indispensable role in the development of Chinese culture. It is the spiritual pillar of Chinese sustainable development. There are no others that can compare with its teaching method and art. The famous "heuristic teaching theory" is one of its greatest inventions. But many people think that it is Socrates invention. In fact, Socrates "elicitation teaching theory" was invented far later than that of Confucius. This paper aims at investigating of these two theories. 展开更多

In decision modeling with influence diagrams, the most challenging task is probability elicitation from domain experts. It is usually very difficult for experts to directly assign precise probabilities to chance nodes. In this paper, we propose an approach to elicit probability effectively by using the concept of interval probability (IP). During the elicitation process, a group of experts assign intervals to probabilities instead of assigning exact values. Then the intervals are combined and converted into the point valued probabilities. The detailed steps of the elicitation process are given and illustrated by constructing the influence diagram for employee recruitment decision for a China’s IT Company. The proposed approach provides a convenient and comfortable way for experts to assess probabilities. It is useful in influence diagrams modeling as well as in other subjective probability elicitation situations. 展开更多

Requirements elicitation is a fundamental phase of software development in which an analyst discovers the needs of different stakeholders and transforms them into requirements.This phase is cost-and time-intensive,and a project may fail if there are excessive costs and schedule overruns.COVID-19 has affected the software industry by reducing interactions between developers and customers.Such a lack of interaction is a key reason for the failure of software projects.Projects can also fail when customers do not know precisely what they want.Furthermore,selecting the unsuitable elicitation technique can also cause project failure.The present study,therefore,aimed to identify which requirements elicitation technique is the most cost-effective for large-scale projects when time to market is a critical issue or when the customer is not available.To that end,we conducted a systematic literature review on requirements elicitation techniques.Most primary studies identified introspection as the best technique,followed by survey and brainstorming.This finding suggests that introspection should be the first choice of elicitation technique,especially when the customer is not available or the project has strict time and cost constraints.Moreover,introspection should also be used as the starting point in the elicitation process of a large-scale project,and all known requirements should be elicited using this technique. 展开更多

In order to develop quality software that meets the originals needs of its users, it is necessary to perform the Requirements Engineering, so that the software context to be developed is identified, examined and specified properly. However, there is a problem that is increasingly in debate: the difficulty in understanding and establishing the purpose of the software to be developed, as pointed out by important researches in the area, such as the Chaos Report, which indicates that only 29% of software projects are successful, and the Software Engineering Institute, which points out software requirements as a critical factor for the success of software engineering and that deficiencies in this dimension are the main causes of software project failures. This article presents a proposal to address this problem through the use of the Hermeneutical Elicitation of Requirements, which is the conceptual adequacy of some hermeneutical methods in a technical approach that assists the requirements engineer to conceive better of the software requirements. In this way, the software engineer will be better able to develop the software to better meet the needs of its end users and sponsors. 展开更多

A challenge for many School-Based Family Counseling(SBFC)practitioners,child psychotherapists and researchers are finding ways to give voice to children and eliciting trustworthy and detailed narratives that could serve as resource for understanding the needs of young clients in the context of all their interpersonal networks.Children are often reticent when asked to self-disclose and tell their stories during consultation.The purpose of the present study was to examine the utility of five sequential steps constituting the Collage Life Story Elicitation Technique(CLET)for scaffolding storytelling among children in middle childhood(aged 9-12 years).Using the CLET for data collection and conducting an interpretive analysis,the researchers explored the performance of 38 middle-childhood children living in three different settings.Findings suggest that the five sequential steps of the CLET adequately and satisfactorily combine to stimulate and elicit rich data and help children to construct their narratives and represent the challenges they face in everyday living.We discuss the application of CLET in SBFC practice as tool when screening and intervention planning for children’s perspectives pertaining to a range of topics regarding each of the four quadrants as proposed in the SBFC metamodel. 展开更多
