Nanotechnology is a novel technological field said to be one of the key technologies in the 21st century revoltionizing information
technology, materials and medicine. Bibliometric quantification is a way to show the emergence of a new technology.Braun et al.1 could establish an exponential growth pattern of publications in nano-science and technology starting in the early 1990s.
Using their study as basis we intend to further characterize nanotechnology using bibliometric as well as patent data. We
can show that the share of boundary-spanning publications is exceptionally high in the field of nanotechnology. Our co-authorship
analysis indicates that countries follow different patterns of collaboration. Some countries tend to have bilateral relations
while others collaborate with a much larger array of nations. Patent data in combination with bibliometric reveals differences
in the application of science. In our conclusion we raise a number of questions requiring an analysis using also other types
of data. Still, a closer investigation and disaggregation of bibliometric data may come up with additional findings.
Az adaptív számítógépes tesztelés (CAT) a kognitív képességek mérésének legkorszerűbb formája, amely egyfelől a modern tesztelméletre, másfelől az informatikai lehetőségekre épül. Jelen tanulmányban egy gyakorlati példán, a Mensa HungarIQa adaptív IQ-tesztjén keresztül mutatjuk be a CAT elméletét és gyakorlatát. A cikk először áttekinti az intelligencia kutatásának legfontosabb eredményeit és az IQmérés történetét és módszereit. Ezt követően a pszichometria főbb területeit, a klasszikus tesztelméletet és az item-válasz elméletet tárgyalja, valamint a CAT alapjait. Végül bemutatja egy konkrét adaptív IQteszt készítésének folyamatát, az itemek készítésétől az item-paraméterek becslésén és az adaptív algoritmus összeállításán át a teszt validálásáig.
In Hungary, there is an active practice for inspecting crimes committed in information technology environments as well as crimes affecting intellectual property as the two areas often overlap. Recently a criminal infringement of copyright occurred in a very special environment — the virtual world of Second Life. In this paper, the questions raised by the above-mentioned case from a legal and IT forensic perspective will be present along with the recommended answers from the authors.
The first half of the paper will present the specialties of virtual world environments and how the criminal investigation was started. General criminal procedure norms governing IT forensics will be discussed. The question of how copyright law protects avatars or virtual items in Second Life and how the financial value of a virtual item can be determined will be answered. The remainder of the paper will present, in detail, the IT forensic examination of the concrete criminal case where illegal copies of avatars appeared in Second Life. The question regarding how digital evidences can be obtained from simulated virtual environments from a legal and IT forensic perspective will be discussed in details.
The paper was written in order to stimulate interest in the special field of relationship between IT forensics, criminal law and virtual worlds because there are hardly any articles dealing with the aforementioned problem in scientific literature.

Dietary fibres (DFs) are essential components of the balanced diet. Even though the adequate level of their consumption can be ensured from several natural (e.g. fruit, vegetables, legumes) and ‘artificial’ sources (e.g. functional foods), the consumed levels are below the recommendations. To analyse the Hungarian and Romanian consumers’ knowledge level, their perceptions of the health benefits associated with fibre, as well as the recognition of the potential information sources, a survey questionnaire was conducted with the total of 713 consumers. Results showed that the level of knowledge about DFs was not adequate. Internet was found to be widely used and identified as one of the most appropriate information sources to encourage the consumption of DF. It was a favourable result that three-quarter of the respondents was interested in the topic of healthy food consumption; however, just less than half of them took into consideration the label information during their shopping decisions. To increase the consumption of DF and to support the responsibility and conscious consumer decisions steps must to be done (e.g. education of children, pointing out of the sources). For this purpose, modern information technology and communication channels fitting to the consumers’ cultural and personal particularities can be utilized.
The present study’s primary objective is to identify contributing factors in selecting and evaluating a seafood supplier within the Taiwanese hospitality industry. It illustrates the application of a multicriteria decision-making process to supplier selection within a service setting where it is less common than in a manufacturing context. To implement the study, a survey instrument was created and submitted to Taiwanese hospitality firms, namely hotels and restaurants, to identify contributing factors in the selection of a seafood supplier within six initial areas concerning food hygiene, stafftraining, crisis management, information technology, competitive ability, and logistics and quality assurance. The analytic hierarchical process (AHP) was then applied to the survey results, and the first- and second-level hierarchical factors were rigorously identified and ranked. These can be regarded as useful benchmarks in identifying and ranking the selection and evaluation of a food supplier within the industry. The present study enhances the understanding of supplier selection in the hospitality industry and provides insights which hospitality firms can apply in managing their supply chains. The managerial and research implications of these findings are discussed.
