Food Literacy: Key Concepts for Health and Education

Globally, the food system and the relationship of the individual to that system, continues to change and grow in complexity. Eating is an everyday event that is part of everyone’s lives. There are many commentaries on the nature of these changes to what, where and how we eat and their socio-cultural, environmental, educational, economic and health consequences. Among this discussion, the term "food literacy" has emerged to acknowledge the broad role food and eating play in our lives and the empowerment that comes from meeting food needs well. In this book, contributors from Australia, China, United Kingdom and North America provide a review of international research on food literacy and how this can be applied in schools, health care settings and public education and communication at the individual, group and population level. These varying perspectives will give the reader an introduction to this emerging concept. The book gathers current insights and provides a platform for discussion to further understanding and application in this field. It stimulates the reader to conceptualise what food literacy means to their practice and to critically review its potential contribution to a range of outcomes.

Some new concepts in nonlinear systems

Some new concepts characterizing the response of nonlinear systems are developed. These new concepts are denoted by the terms, the transient system equivalent, the response vector, and the space-phase components. This third concept is analyzed in comparison with the well-known technique of symmetrical components. The performance of a multiplicative feedback control system is represented by a nonlinear integro-differential equation; its solution is obtained by the principle of variation of parameters. The system response is treated as a vector and is resolved into its space-phase components. The individual effects of these components on the performance of the system are discussed. The suitability of the technique for the transient analysis of higher order nonlinear control systems is discussed.

Solution concepts in two-person multicriteria games

In this paper, we propose new solution concepts for multicriteria games and compare them with existing ones. The general setting is that of two-person finite games in normal form (matrix games) with pure and mixed strategy sets for the players. The notions of efficiency (Pareto optimality), security levels, and response strategies have all been used in defining solutions ranging from equilibrium points to Pareto saddle points. Methods for obtaining strategies that yield Pareto security levels to the players or Pareto saddle points to the game, when they exist, are presented. Finally, we study games with more than two qualitative outcomes such as combat games. Using the notion of guaranteed outcomes, we obtain saddle-point solutions in mixed strategies for a number of cases. Examples illustrating the concepts, methods, and solutions are included.

Network Knowledge versus Cluster Knowledge- The Gordian Knot of Knowledge Transfer Concepts

Both management scholars and economic geographers have studied knowledge and argued that the ability to transfer knowledge is critical to competitive success. Networks and other forms for cooperation are often the context when analyzing knowledge transfer within management research, while economic geographers focus on the role of the cluster for knowledge transfer and creation. With the common interest in knowledge transfer, few attempts to interdisciplinary research have been made. The aim of this paper is to outline the knowledge transfer concepts in the two strands of literature of management and economic geography (EG). The paper takes an analytical approach to review the existing contributions and seek to identify the benefits of further interaction between the disciplines. Furthermore, it offers an interpretation of the concepts of cluster and network, and suggests a clearer distinction between their respective definitions. The paper posits that studies of internal networks transcending national borders and clusters are not necessarily mutually exclusive when it comes to transfer of knowledge and the learning process of the firm. Our conclusion is that researchers in general seem to increasingly acknowledge the importance of studying both the effect of and the need for geographical proximity and external networks for the knowledge transfer process, but that there exists equivocalness in defining clusters and networks.

Networks, Organisations and Men: Concepts and Interrelations

Research on men’s networks and homosociality in and around organisations can produce knowledge on organisational power relations, and contribute to the efforts to promote equality in working life. The search for a conceptual framework to study these issues arises in this paper from my ongoing work on men's social networks and gendered power in and around organisations. Men give each other social support through networks in which formal and informal relationships intermingle, but networks are also contexts of competition and oppression, and of construction of masculinities that are in hierarchical relations with each other and with femininities. For studying the networks men have with each other in work organisations I suggest a broader starting point that contextualises these homosocial networks with men’s other personal relations, and integrates different perspectives deriving from social network analysis, critical studies on men and organisational studies.

Interpretation of Services Marketing Concepts

Scholarly research has produced conceptual knowledge that is based on real-life marketing phenomena. An initial aim of past research has been to produce marketing knowledge as a base for efficient business operation and for the improvement of productivity. Thus, an assumption has been that the knowledge would be applied by organisations. This study focuses on understanding the use of marketing knowledge within the field of service marketing. Hence, even if marketing knowledge about service-oriented principles and marketing of services is based on empirical research, there is a lack of knowledge on how this marketing knowledge is in fact applied by businesses. The study focuses on four essential concepts of services marketing knowledge, namely service quality, servicescape, internal marketing, and augmented service offering. The research involves four case companies. Data is based on in depth interviews and questionnaire-based surveys conducted with managers, employees, and customers of these companies. All organisations were currently developing in a service-oriented and customer-oriented direction. However, we found limitations, gaps, and barriers for the implementation of service-oriented and customer-oriented principles. Hence, we argue that the organisations involved in the study exploited conceptual knowledge symbolically and conceptually, but the instrumental use of knowledge was limited. Due to the shortcomings found, we also argue that the implementation of the various practices and processes that are related to becoming service-oriented and customer-oriented has not been fully successful. Further, we have come to the conclusion that the shortcomings detected were at least in some respect related to the fact that the understanding and utilisation of conceptual knowledge of service-oriented principles and marketing of services were somewhat limited.

Concepts of Narrative

Transposed to media like film, drama, opera, music, and the visual arts, “narrative” is no longer characterized by either temporality or an act of telling, both required by earlier narratological theories. Transposed to other disciplines, “narrative” is often a substitute for “assumption”, “hypothesis”, a disguised ideological stance, a cognitive scheme, and even life itself. The potential for broadening the concept lay dormant in narratology, both in the double use of “narrative” for the medium-free fabula and for the medium-bound sjuzet, and in changing interpretations of “event”. Some advantages of the broad use of “narrative” are an evocation of commonalities among media and disciplines, an invitation to re-think the term within the originating discipline, a constructivist challenge to positivistic and foundational views, an emphasis on a plurality of competing “truths”, and an empowerment of minority voices. Conversely, disadvantages of the broad use are an illusion of sameness whenever the term is used and the obliteration of specificity. In a Wittgensteinian spirit, the essay agrees that concepts of narrative are mutually related by “family resemblance”, but wishes to probe the resemblances further. It thus postulates two necessary features: double temporality and a transmitting (or mediating) agency, and an additional cluster of variable optional characteristics. When the necessary features are not dominant, the configuration may have “narrative elements” but is not “a narrative”.

Solution concepts in continuous-kernel multicriteria games

This paper considers nonzero-sum multicriteria games with continuous kernels. Solution concepts based on the notions of Pareto optimality, equilibrium, and security are extended to these games. Separate necessary and sufficient conditions and existence results are presented for equilibrium, Pareto-optimal response, and Pareto-optimal security strategies of the players.

New Concepts for PVC Detection

A new scheme is proposed for the detection of premature ventricular beats, which is a vital function in rhythm monitoring of cardiac patients. A transformation based on the first difference of the digitized electrocardiogram (ECG) signal is developed for the detection and delineation of QRS complexes. The method for classifying the abnormal complexes from the normal ones is based on the concepts of minimum phase and signal length. The parameters of a linear discriminant function obtained from a training feature vector set are used to classify the complexes. Results of application of the scheme to ECG of two arrhythmia patients are presented.

Concepts of Static Var System Control For Enhancing Power Transfer in Long Transmission Lines

This paper is concerned with the influence of different levels of complexity in modelling various constituent subsystems on the dynamic stability of power systems compensated by static var systems (SVS) operating on pure voltage control. The system components investigated include thyristor controlled reactor (TCR) transients, SVS delays, network transients, the synchronous generator and automatic voltage regulator (AVR). An overall model is proposed which adequately describes the system performance for small signal perturbations. The SVS performance is validated through detailed nonlinear simulation on a physical simulator.

Parallel computing concepts and methods for floquet analysis of helicopter trim and stability

Floquet analysis is widely used for small-order systems (say, order M < 100) to find trim results of control inputs and periodic responses, and stability results of damping levels and frequencies, Presently, however, it is practical neither for design applications nor for comprehensive analysis models that lead to large systems (M > 100); the run time on a sequential computer is simply prohibitive, Accordingly, a massively parallel Floquet analysis is developed with emphasis on large systems, and it is implemented on two SIMD or single-instruction, multiple-data computers with 4096 and 8192 processors, The focus of this development is a parallel shooting method with damped Newton iteration to generate trim results; the Floquet transition matrix (FTM) comes out as a byproduct, The eigenvalues and eigenvectors of the FTM are computed by a parallel QR method, and thereby stability results are generated, For illustration, flap and flap-lag stability of isolated rotors are treated by the parallel analysis and by a corresponding sequential analysis with the conventional shooting and QR methods; linear quasisteady airfoil aerodynamics and a finite-state three-dimensional wake model are used, Computational reliability is quantified by the condition numbers of the Jacobian matrices in Newton iteration, the condition numbers of the eigenvalues and the residual errors of the eigenpairs, and reliability figures are comparable in both the parallel and sequential analyses, Compared to the sequential analysis, the parallel analysis reduces the run time of large systems dramatically, and the reduction increases with increasing system order; this finding offers considerable promise for design and comprehensive-analysis applications.
