[en] The digital transformations that shape and condition the context in which we move are based on an apparent dichotomy between autonomy and collaboration. From this base and taking advantage of hyper connectivity phenomena, the consequences for the knowledge management in its broadest sense, and its involvement in concepts such as smart planet, are analyzed. This concept determines the evolution of organizations towards intelligent (smart) and opens conceptions that influence, in turn, a redesign of teaching-learning processes in the framework of organizations in accordance with these demands. The future bet of Tecnatom is to respond to the challenges that this situation poses in the nuclear and technological sector. (Author)
[en] Highlights: • Serendipity as a control mechanism for knowledge diffusion in social network. • Local communication enhanced in the periphery of a network. • Prevalence of hub nodes in the network core mitigated. • Potential disruptive effect on network formation of uncontrolled serendipity. - Abstract: In this paper, we study serendipity as a possible strategy to control the behavior of an agent-based network model of knowledge diffusion. The idea of considering serendipity in a strategic way has been first explored in Network Learning and Information Seeking studies. After presenting the major contributions of serendipity studies to digital environments, we discuss the extension to our model: Agents are enriched with random topics for establishing new communication according to different strategies. The results show how important network properties could be influenced, like reducing the prevalence of hubs in the network’s core and increasing local communication in the periphery, similar to the effects of more traditional self-organization methods. Therefore, from this initial study, when serendipity is opportunistically directed, it appears to behave as an effective and applicable approach to social network control.
[en] The Thermochemical Database (TDB) Project was created three decades ago as a joint undertaking of the NEA Radioactive Waste Management Committee and the NEA Data Bank. The project involves the collection of high-quality and traceable thermochemical data for a set of elements (mainly minor actinides and fission products) relevant to geophysical modelling of deep geological repositories. Funding comes from 15 participating organisations, primarily national nuclear waste authorities and research institutions. The quantities that are stored in the TDB database are: the standard molar Gibbs energy and enthalpy of formation, the standard molar entropy and, when available, the heat capacity at constant pressure, together with their uncertainty intervals. Reaction data are also provided: equilibrium constant of reaction, molar Gibbs energy of reaction, molar enthalpy of reaction and molar entropy of reaction. Data assessment is carried out by teams of expert reviewers through an in-depth analysis of the available scientific literature, following strict guidelines defined by the NEA to ensure the accuracy and self-consistency of the adopted datasets. Thermochemical data that has been evaluated and selected over the years have been published in the 13 volumes of the Chemical Thermodynamics series. They are also stored in a database that is updated each time the study of a new element is completed. The TDB selected data are made available to external third parties through the NEA web site where data extracted from the database can be displayed and downloaded as plain text files. Following recent recommendations of the Task Force on the Future Programme of the NEA Data Bank to enhance scientific expertise and user services, a renewal of the software managing the TDB database is being undertaken. The software currently used was designed 20 years ago and is becoming obsolete. Redesigning the application will provide an opportunity to correct current shortcomings and to develop new functionalities that will greatly improve the quality of the tool, both on the technical and conceptual levels. The main goal of the renewal is to meet the technological standards of modern thermochemical databases, including the preparation of a thorough documentation of the technical and functional features of the tool, and to envisage greater flexibility and options for end users, accompanied by a more robust and reliable management of the data to facilitate its maintenance. The upgrading work that will be performed involves redesigning both the Oracle database (back end) and the web interface (front end). The main axes of improvement are detailed in this paper. As an international reference within the radioactive waste management community, it has proven vital to introduce certain improvements to the TDB database in order to maintain the high quality and reliability that have always characterised the distributed data. The renewal of the database is therefore being undertaken to meet the current standards for high-quality thermochemical databases and to broaden the possibilities offered to end users

[en] Organizational knowledge is the sum of individual and collective knowledge, explicit and tacit knowledge, expertise, experience, skills and abilities within an organization that can be used to achieve better results, to provide better services or to create another intangible asset for the organization. Organization can gain competitive advantage in the market using organizational knowledge. Organizational knowledge is also in organizational structure, routines and business processes as well as in developed relationships. Culture is human behaviour we learned and usually we are sharing in some environment. It is way of living and working. Culture contains ideals, values and rules connected with individual and group behaving. Same approach is for organizational culture but organization assures space and time for culture development according to own needs. Organizational culture with its core values is an important factor in the creation and sharing of organizational knowledge as main activities in organizational knowledge management. As such organizational culture should be developed and incorporated into organizational knowledge. (author).
[en] Purpose: The purpose of the study was to determine how radiographers learn and to explore how this may affect professional learning. Method: Twenty copies of Kolb’s Learning Style Inventory 1985 were distributed to each of a random sample of 31 hospitals in one health region. The response rate was 84% (n=26) of hospitals yielding a useable questionnaire return of 224. Results: On the continuum representing perception of information 75% (n=169) of respondents scored higher on the learning attribute of abstract conceptualisation than concrete experience. Twenty percent (n=45) scored higher on concrete experience than abstract conceptualisation. Five percent (n=10) had equal scores. On the continuum representing processing of information 73% (n=164) scored higher on the learning attribute of active experimentation than reflective observation. Twenty-four percent (n=53) scored higher on reflective observation than active experimentation and 3% (n=7) had equal scores. The calculation of the learning attribute preferences led to determination of learning style. Thirty-three percent were found to be convergers, 33% assimilators, 21% accommodators and 13% divergers. Conclusions: The weaker learning attributes are concrete experience and reflective observation and therefore in general radiographers miss drawing out the full potential of all the learning experience has to offer. The predominant learning style score was converger and assimilator (66%) demonstrating strength in practical application of ideas and ability to create theoretical models respectively. The information obtained may be used to help radiographers optimise their life long learning and also to facilitate a closer match of teaching styles to those of the learners.
[en] Purpose: Many radiographers applying for postgraduate study are qualified with the Diploma of the College of Radiographers. These radiographers are deemed to be non-standard entrants at St. Martin’s College, Lancaster, whereas graduates with a second class honours degree or above, are deemed to be standard entrants. This paper will discuss the admission of such students to postgraduate courses via Accreditation of Prior Learning (APL) and Accreditation of Prior Experiential Learning (APEL), and their subsequent achievement on postgraduate courses. Method:Data (student marks) were extracted from student records from 1994 to the present time, for the four programmes run in the Department of Radiography and Imaging Sciences. Analysis of the data provided total numbers of standard and non-standard students on each programme as well as the mark range, standard deviation and mean marks for each programme. It was then determined, using at -test for independent samples, whether there was any statistically significant difference in the marks of standard and non-standard entrants per programme and also collectively. Results: The results showed that there was no statistically significant difference in the marks achieved by standard or non-standard entrants on any of the four programmes. Conclusion: If assessment outcomes are used as an indicator of academic performance this study demonstrates that widening participation, to allow those DCR radiographers motivated enough to apply to study at postgraduate level direct entry onto postgraduate courses, does not lower academic standards.
