Cyber range design framework for cyber security education and training

The need for effective training of cyber security personnel working in critical infrastructures and in the corporate has brought attention to the evolution of Cyber Ranges (CRs) as learning and training tools. Although CRs have been organized for many years, there is a lack of standards and common methodologies that facilitate their development and optimize their effectiveness. Aiming at strengthening cyber security education and research that utilize well designed CRs, we first analyze the CRs domain to identify key characteristics, strengths and fundamental weaknesses, and based on these outcomes we propose the Cyber Range Design Framework (CRDF), which includes the CR Architecture and the CR Life-Cycle. The CR Architecture presents the main components of CRDF compliant CRs, whereas the CR Life-Cycle presents the development phases of such approaches and the activities these phases embrace. CRDF builds on the Conceptual Framework for eLearning and Training (COFELET) and on the Exercise Life-Cycle. COFELET is particularly elaborated for the development of cyber security educational approaches, by adopting its design considerations that were based on widely adopted educational theories and approaches (e.g., scenario-based, reuse of elements). CRDF envisages the elaboration of CRs which optimize their impact, mitigate their weaknesses, and minimize their preparation and running costs. Under this prism, a preliminary appreciation of the CRDF approaches effectiveness is presented along with the expected outcomes of such approaches.

Current Status and Future Trends of Power Quality Analysis

In this article, a systematic literature review of 153 articles on power quality analysis in PV systems published in the last 20 years is presented. This provides readers with an overview on PQ trends in several fields related to instrumental techniques that are being used in the smart grid to visualize the quality of the energy, establishing a solid literature base from which to start future research. A preliminary appreciation allows us to intuit that higher-order statistics are not implemented in measurement equipment and that traditional instrumentation is still used for the performance of measurement campaigns, not yielding the expected results since the information processed does not come from an electrical network from 20 years ago. Instead, current networks contain numerous coupled load effects; thus, new disturbances are not simple; they are usually complex events, the sum of several types of disturbances. Likewise, depending on the type of installation, the objective of the PQ analysis changes, either by detecting certain events or simply focusing on seeing the state of the network.

Construction of yeast two-hybrid cDNA libraries for wheat near-isogenic line TcLr19 under the stress of Puccinia recondita and its preliminary appreciation

Two cDNA libraries for wheat near-isogenic line TcLr19 under Puccinia recondita stress were constructed by using SMART technique and homologous reorganization method. Wheat near-isogenic line TcLr19 was infected with leaf rust race 366, and total RNA was extracted from the leaves after infection for 4, 8, and 12 h. The total RNAs were reverse transcribed to cDNA by using oligo(dT) primer and random primer, respectively. According to the evaluation on quality, the transformation efficiency was about 1.32 × 106 and 1.0 × 106 transformants/3 μg pGADT7-Rec, respectively, and the library titers were up to 2.62 × 108 and 3.51 × 108 pfu/mL, with 93% and 100% recombinant rate, which indicated the high quality of the two libraries for next screening.

Jean Rudduck (1937–2007) ‘Carving a new order of experience’: a preliminary appreciation of the work of Jean Rudduck in the field of student voice

This paper offers a preliminary tribute to the work of the late Jean Rudduck, pioneer of student voice, both as an academic field and as a potential agent of school transformation. Tracing the roots of her student voice work back to CARE (Centre for Applied Research in Education) and the Humanities Curriculum Project (1967–1972), the author follows the intellectual narrative of her student voice work from the mid‐1990s up to and including her forthcoming (2007) book, Improving learning through consulting pupils, co‐authored with Donald McIntyre. The paper closes by suggesting eight aspects of Jean Rudduck’s work that make a distinctive, enduring contribution to the field of student voice and thereby to a more humane, more creative approach to education in and for democracy.

Global Data Assimilation Experiments with Scatterometer Winds from SEASAT-A

Abstract Two days of global scatterometer-derived oceanic surface winds during the period of 0000 GMT 16 July-0000 GMT 18 July 1978 from the SEASAT-A satellite are used in the NMC's global data assimilation and forecast experiments to gain a preliminary appreciation of the impact of this dataset. The NMC's global data assimilation system used in this study is described. The nature of the scatterometer winds and their error characteristics are discussed. Two parallel 48-hour data assimilation experiments are conducted: one including scatterometer wind data (SASS), the other without (NCSASS). After 48 hours of assimilation, large differences have evolved between SASS and NOSASS analyses due to the scatterometer winds. Comparison of the analyses with the operational analysis generated by the Australian Bureau of Meteorology suggests that the influence of scatterometer winds was beneficial in the Southern Hemisphere.

Quantum chemical modelling of reactions in hydrocarbon combustion. Study of the CH4 + O2 reactions

The rate constants of two alternative reactions, i.e CH4 + O2 → CH2 + H2O2 and CH4 + O2 → CH3 + HOO have been studied by the ab initio and MINDO/3 methods. A preliminary appreciation of the used methods has been done with a selected set of carbene reactions. The characteristics of minima as well as the saddle points on the corresponding reaction paths of both reactions have been found. The discussion of the relative probability of a pathway of the above-mentioned reactions is based on the rate constants determined by the use of transition state theory.

The Role of Compulsion in the Education of Plato's Philosopher-King

In this paper we will examine a question which is of central importance to a thorough understanding of Plato's Republic. Specifically, we will be asking about the role of in education as it is described in the Republic. At the outset this question must of necessity remain a bit ambiguous since its central role in a dialogue which is ostensibly about justice is not at first apparent, nor are the precise meanings of the terms compulsion and education. During the course of the paper, however, this will be brought into much sharper focus as I argue from the position that, on its most fundamental level, the Republic is concerned in a more significant way with education (paideia) than with justice. As for the idea of itself, we need to begin with a preliminary appreciation of just how thoroughly it permeates the Republic. Let us consider some of the senses this word can have. Most obviously, one can speak of physical whereby the strong compels the weak. This can occur either on the level of one man compelling a weaker man to do his bidding, or on the level of a state compelling a man to act in a certain way, as for example when a state enslaves someone. In each case physical force is used to intimidate the weak for the benefit of the strong. The reader will of course recognize this sort of as underlying Thrasymachus' definitions of justice in Book I. Another similar sort of which is also pervasive in the Republic is in fact at issue in the opening scene of the dialogue. There, it will be recalled, Socrates and Glaucon are detained by Polemarchus' slave boy and are compelled by threat of physical force to remain the Piraeus. A third form of compulsion, the most pervasive form in the Republic, is the which a good argument exerts on those who hear it, or the exerted by dialectic truth.

Harvey Sacks: A Preliminary Appreciation

Harvey Sacks, Professor of Anthropology and Sociology at the University of California at Irvine in the United States, was killed in an automobile accident near the Irvine campus in November of last year. His death was both a stunning personal loss to his family, friends and close associates and a great professional loss to those of us (in several disciplines) who had felt the impact of his intellectual achievements. We have lost in Sacks one of our most original and brilliant colleagues. I do not presume now to present in this brief essay anything more than a preliminary appreciation of Sacks' pervasive influence upon some of us, and to document more than the most general parameters of his academic life. Much will be left untold, for others to tell. It seemed fitting, however, to put on record at this time a version of his intellectual significance which is not usually otherwise available within British sociology. Harvey Sacks worked out and developed what has come to be understood as Conversation Analysis. His first published paper, 'Sociological Description',1 articulated in ethnomethodological terms how the analyst might resolve the problem of describing social phenomena empirically encountered. For Sacks, nothing was to be permitted to enter the analyst's technical apparatus until its commonsense ways of being produced and recognized as such had been thoroughly elucidated. Without such elucidation, the sociological analyst would merely be trading upon his common-sense linguistic and cultural resources without ever subjecting them to analytical scrutiny. Published in 1963, this paper anticipated, and certainly influenced, the terms in which much subsequent discussion of the 'topic-and-resource' problem was conducted. Between 1963 and 1964, Sacks worked as a Fellow of the Center for the Scientific Study of Suicide in Los Angeles, and his research there provided him with the materials for his doctorate, a version of which was subsequently published as: 'The Search for Help: No One to Turn To'.2 In this piece, one can locate the basis for, and some of the elements of, what he turned into his most original and fertile contribution to the discipline: the formal analysis of naturally-occurring practical activities. At this point, Sacks' interest in members' linguistic and cultural resources and their detailed display had become his major research focus. The problems involved in producing sound,

The planning of site investigations for highways

Summary A site investigation covers three stages, a preliminary appreciation of the site, a ground investigation in which borings and laboratory testing are undertaken, and a final stage in which the conclusions of the ground investigation are checked against the actual ground conditions as revealed by the constructional excavations. This paper considers the planning and implementation of the ground investigation under conditions normally prevailing in the British Isles. Various procedures are described for boring in soils and rocks, for trial excavations, for probing, and for geophysical surveying. Sampling procedures are considered on the basis of the quality of the sample thus obtained. Sample quality ranges between almost fully-undisturbed soil samples as taken by a thin-wall piston sampler, and fully disturbed samples taken from the drill tools. The choice of procedure for boring and sampling is determined by the technical requirements of the investigation, by the practical problems arising from site conditions and by economy. It is considered that investigations should start using standard equipment and that the more sophisticated and expensive procedures should be employed only when the nature of the geotechnical problem has been determined. The paper concludes with a discussion of the management and organization of site investigations.
