The paper aims to investigate and describe the complex and dynamic dilemmas teachers are facing connected to students' net-based out-of-school activities.

The authors draw on the notion of dilemmatic spaces when thematically analyzing focus group interviews conducted with 41 teachers at three lower secondary schools in Sweden.

Two themes capture the teachers' dilemmas concerning their students´ net-based out-of-school activities: negotiations of content and negotiations of professional identity. When teachers take part in professional discussions where dilemmatic spaces are recognized, rather than focusing on either being for or against digitalization, they are enabled to express a multifaceted view of professional identity.

This study is a starting point for further studies investigating how pedagogical and didactic decisions are made in a digital time.

The findings are expected to be helpful to policymakers in understanding teachers' work. Also, teachers can be empowered by taking the departure in the findings and discussing how to handle dilemmas fruitfully.

In a rapidly changing digital society, it is important to investigate what dilemmas teachers face in their work in order to learn from them. This study is a significant contribution.

How would a learning arena that promotes “just‐in‐time” learning in the workplace ideally be created? This was one of the most important questions the Norwegian research project, NEMLIG, aimed to illustrate through a series of work place experiments. The present article presents the evaluation of the project in the form of a number of dilemmas. These are clustered into three categories: those that related to present and future work organisation, those related to the user‐interface, and those dealing with user‐participation and systems development.

The progress of life science and social science research is contingent on effective modes of data storage, data sharing and data reproducibility. In the present digital era, data storage and data sharing play a vital role. For productive data-centric tasks, findable, accessible, interoperable and reusable (FAIR) principles have been developed as a standard convention. However, FAIR principles have specific challenges from computational implementation perspectives. The purpose of this paper is to identify the challenges related to computational implementations of FAIR principles. After identification of challenges, this paper aims to solve the identified challenges.

This paper deploys Petri net-based formal model and Petri net algebra to implement and analyze FAIR principles. The proposed Petri net-based model, theorems and corollaries may assist computer system architects in implementing and analyzing FAIR principles.

To demonstrate the use of derived petri net-based theorems and corollaries, existing data stewardship platforms – FAIRDOM and Dataverse – have been analyzed in this paper. Moreover, a data stewardship model – “Datalection” has been developed and conversed about in the present paper. Datalection has been designed based on the petri net-based theorems and corollaries.

This paper aims to bridge information science and life science using the formalism of data stewardship principles. This paper not only provides new dimensions to data stewardship but also systematically analyzes two existing data stewardship platforms FAIRDOM and Dataverse.

The purpose of this paper is to explore what options the adult learner has for continued learning and what role universities are playing in providing net-based education. Current options for lifelong learning and improvement opportunities in the educational process are described based on an assessment inspired by principles of lean management.

Sweden is chosen as an example. The current level of net-based university education and the demand for it is assessed using official Swedish data. Lean management principles are used as a starting point to define parameters for interest for the adult learner. These parameters are then converted into a five-level scale for assessing current performance with focus on university courses. The authors also study how Swedish County Councils manage their employee education and carry out a check of courses offered by massive open online course providers.

Lean management principles in combination with customer focus seem to present relevant parameters for assessing distance education. Preliminary results indicate that lean lifelong learning has a considerable improvement potential. The main reasons for this potential seem to be more of a bureaucratic and political nature, whereas technology and resources appear to be less of an issue.

The results have implications for both universities and organisations. The pressure on universities to become more customer-focussed, while at the same time, cost-effectiveness is likely to increase.

Using the customer perspective for educational services and applying lean principles to education.

Considers an integrated approach to maintenance management, based on the development of an advanced machine tool failure diagnosis and recovery system. Outlines how such systems can be utilized to effectively monitor the ever more complicated machining facilities used in modern manufacturing. Illustrates how a Petri‐net based system has been developed to meet the needs of a modern computer‐based maintenance facility and the potential that such systems provide in a move towards total productive maintenance. Deals with the steps taken to ensure that such a system can be successfully deployed, and considers how the resulting integrated maintenance management system can benefit existing users of advanced manufacturing technology.

Describes the ongoing development of a Petri‐Net‐based machine tool failure diagnosis system. The described system incorporates condition monitoring systems and expert system‐based diagnostic tools. Brings these together with the Petri‐Net monitoring system to form an integrated fault location and rectification package and an associated maintenance management system.

After the occurrence of a disaster, emergency supplies should arrive at disaster area in the shortest possible time. Therefore, it is of pivotal importance to speed up the preparation and scheduling process. In other words, only when the preparation process and scheduling process coordinate well, could the emergency supplies arrive at disaster area in time. Consequently, the purpose of this paper is to explore a method that can strengthen the coordination in various kinds of situations.

The paper first elaborates the preparation and scheduling process of emergency supplies in disasters. Then, it establishes a workflow simulation system of the emergency supplies preparation and scheduling based on Petri Net. Afterward, the paper proposes a simplified simulation system of emergency supplies preparation and scheduling which can be employed in actual emergency response. Finally, the paper takes China Lushan Earthquake for a case study.

By employing the simulation system proposed by this paper, decision makers can simulate the whole emergency supplies preparation and scheduling process, which can help them find a method that can optimize the current process. Specifically, by analyzing the simulation results, the government can obtain conclusions as follows. First, whether the preparation and scheduling process of emergency supplies can speed up or not. Second, which part of the process should be improved to realize the acceleration. Third, the workload of the staffs and experts. Fourth, whether it is necessary to add staffs or experts to work in parallel.

This paper proposes a system that can coordinate the preparation process and scheduling process of emergency supplies in disaster. Then, it employs the Petri Net based workflow model to do simulation. The simulation results show that the system designed is reasonable and can be used in practical decision making on the preparation and scheduling of emergency supplies.

The potential application of data mining techniques in the extraction of information from property data sets is discussed. Particular interest is focused upon neural networks in the valuation of residential property with an evaluation of their ability to predict. Model testing infers a wide variation in the range of outputs with best results for stratified market subsets, using postal code as a locational delimiter. The paper questions whether predicted outcomes are within the range of valuation acceptability and examines issues relating to potential biasing and repeatability of results.

The Internet is redefining the way in which researchers and consumers can access information on hospitality products and experiences. For example, a growing number of online communities (e.g., http://Tripadvisor.com) offer consumers the opportunity to view and participate in various forums and reviews of hospitality experiences around the world. This has created a rich source of information which researchers can tap into, via Internet-based methodologies, to deepen current understanding of the modern hospitality consumer. Thus, the Internet has become a viable (virtual) fieldwork site for hospitality and other research. However, net-based methods have not been fully embraced in hospitality research. In particular, attention is drawn in this chapter to netnography (online ethnography), a novel, Internet-based research methodology, which has rarely been employed in hospitality research. Further, it is suggested, researchers can complement traditional research techniques with netnography to create more rigorous methodologies.
