The Aerodynamic Forces and Moments on a Spinning Model of the F4B-2 Airplane as Measured by the Spinning Balance

The aerodynamic forces and moments on a 1/12-scale model of the F4B-2 airplane were measured with the spinning balance in nine spinning attitudes with three sets of tail surfaces, namely, F4B-2 surfaces; F4B-4 fin and rudder with rectangular stabilizer; and with all tail surfaces removed. In one of these attitudes measurements were made to determine the effect upon the forces and moments of independent and of simultaneous displacement of the rudder and elevator for two of the sets of tail surfaces. Additional measurements were made for a comparison of model and full-scale data for six attitudes that were determined from flight tests with various control settings. The characteristics were found to vary in the usual manner with angle of attack and sideslip. The F4B-2 surfaces were quite ineffective as a source of yawing moments. The F4B-4 fin and F4B-2 stabilizer gave a greater damping yawing moment when controls were against the spin than did the F4B-2 surfaces but otherwise there was little difference. Substitution of a rectangular stabilizer for the F4B-2 stabilizer made no appreciable difference in the coefficient. Further comparisons with other airplane types are necessary before final conclusions can be drawn as to the relations between model and full-scale spin measurements

Identifying the Components Required Supporting the Application of Effective Knowledge Management Activities in Higher Education Partnerships

The purpose of this research is to use the conceptual model presented by Elezi (2017) and examine what are the requirements needed to apply successful Knowledge Management (KM) Activities in Higher Education (HE) partnerships. This research follows a subjective ontology, which leads towards an interpretivistic epistemological stance through the application of three semi-structured interview questions. Questions were posed to nine elite interviewees (EI) who have been involved in initiating, developing and managing partnerships of Higher Education Institutions (HEIs). The results of this research show that currently HEIs involved in partnerships apply KM Activities although not constantly or very effectively. Answers gathered from the EI infer that shared vision and values amongst partners, leadership and management, communication protocol and development of a KM strategy are essential in designing and applying effective KM Activities that allow HEIs to attain the institutional and partnership objectives

A Guiding Conceptual Framework for Individualised Knowledge Management Model Building

This paper presents a conceptual framework for use, by organizational researchers, knowledge management practitioners and business analysts, as a guide to building Knowledge Management (KM) models. This is accomplished through a careful selection of ten prominent KM models which have been discussed critically and used to deepen the theoretical understanding of KM implementation and development. A critical review of ten KM models offers practitioners, as well as researchers, an examination of the ontological and epistemological backgrounds and origins of existing models’ in order to highlight the required components for composing effective KM models. There is limited research supporting the utilization, adaptation or even adoption of KM models that can assist managers seeking a competitive advantage through the implementation of KM processes. Authors of existing KM models claim to provide holistic KM models but when referring back to the central meaning of knowledge and management concepts those models do not generate a thorough coverage of the required characteristics and components. This paper has critically investigated ten widely acknowledged KM models but recognizes that there is a plethora of KM models emerging which have varied foci. The conceptual review of KM models is not an empirical investigation, moreover, a critical analysis that presents a conceptual framework for KM model building. In carrying out this research study, the paper presents the shortfalls of this theoretical research approach but nevertheless, the proposed conceptual framework is envisaged as having value to both practitioners and researchers. This paper sheds light on a series of concerns related to existing KM models, their origins, constructs, and contextualization. For organizational researchers, knowledge management practitioners and business analysts this research study elaborates on issues related to validity, applicability, and generalizability of KM models and defines a set of criteria for KM model building. The paper also impacts on the science of KM presenting perspectives, scope, and contexts in which knowledge is processed

Enhancing Students Learning Experience Via In-Class Formative Assessments: A Business Studies UK Higher Education Example

This research is focused on investigating the application of curricula design theories as means to improve the delivery of teaching materials for Business Management subjects in Higher Education programmes. Analysis in educational institutions of Business Management curricula delivery shows an emphasis on the relationship between the teaching materials delivered and employability skills embraced by students required for further progression in academia or industry. This research has shown that students have the tendency to prioritise summative assessments by procrastinating, neglecting and lacking engagement and participation in class which will then negatively reflect upon students’ motivation and achievement levels. Therefore, this research seeks to explore the implications deriving from increasing the in- class formative assessments as part of curricula design in regards to enhancing students’ engagement, commitment and motivation. The authors believe that strengthening the formative assessments together with summative assessments will contribute to a better learning experience, thus equip learners with adequate knowledge to assure smooth progression to more challenging academic programmes and/or industry related roles. The methodology of this research includes qualitative grounds, applying observations and focus groups as research techniques. Moreover, the data collected discusses and analyses the findings embracing an interpretivism approach and elements of reliability and validity are also discussed

What culture is your university? Have universities any right to teach entrepreneurialism?

Purpose The purpose of this paper is to discuss the need for universities to develop an entrepreneurial culture and assess higher education practitioners’ opinions of the culture of the university they are working in. Design/methodology/approach The research provides empirical data collected through a survey instrument originally used for a PhD research study; however, this paper focuses on the question set related to culture, which was based on the organisational culture model presented by Quinn in 1988. Findings The findings indicate that a number of respondents reported from a heterogeneous population of higher education institutes predominantly responded they were working within a hierarchy cultural type with many reporting a market cultural type. While respondents from a homogeneous group from a single university reported in the main they were working in a market-driven cultural type with the next main category being a clan culture. Research limitations/implications The study population reported in the main that there is predominantly a market culture in UK universities. However, this research has focused entirely on respondents working within the UK HE sector, thus, has ignored potential differences that could be present within the global HE emerging markets. Originality/value The paper strengthens understanding of the critical importance of innovation and entrepreneurship in universities. Students, scholars, HE policy makers and HE practitioners can gather a range of insights pointed at university culture and rest assured in the main they are market focused

Empirical Analysis of Knowledge Exchange in Higher Education Partnerships: Using Knowledge Elicitation Methods and Techniques

This research identified knowledge management challenges that academics experience when exchanging both forms of knowledge, tacit and explicit, in collaborative projects. The research was conducted qualitatively through the use of consecutive data collection strategies of the large-scale survey; expert panel review; and semi-structured interviews with elite participants in order to gather a deep understanding of the type of challenges academics, working across different disciplines and institutional levels, experience when exchanging tacit and explicit knowledge. Furthermore, the research elicited experts’ knowledge indicating that depending on the expertise and size of the institutions and the timeframe of the partnership, academics can encounter challenges of a strategic, tactical and operational nature. While the institutional leadership and shared vision were seen as a challenge of a strategic nature, the misalignment of expertise and abilities was presented as a tactical challenge. Additionally, the findings show that arrangement of staff, logistics, and facilities required to support the delivery of academic products and services is another challenge which needs addressing in order to support the exchange of knowledge. The crux of this research is the novel use of a tri-part, consecutive data gathering technique, which has been shown to be very useful in providing an effective knowledge elicitation methodology. Notwithstanding that fact, of which purposeful knowledge has been elicited using such techniques, this paper also highlighted that the adopted methodology used should not be seen as a panacea for all qualitative research but, moreover, be adopted as a useful technique in the qualitative researchers’ armory

Investigating Stakeholder Perceptions of ISO Management Systems in the UK Agricultural Sector

This paper considered perceptions from a relatively small sample of case studies but acknowledges other respondents views have been triangulated to an extent that verifies the samples used are representative of the UK agricultural supply chain. The present study provides a starting-point for further research into the adoption and uptake of ISO management systems standards in the UK agricultural sector and its supply chain. Therefore this paper does not explore the relationships between adoption of ISO management systems and the impact of them it rather explores perceptions of different ISO management systems from stakeholders viewpoints. Following an extensive review of stakeholder perceptions this paper concludes that the uptake of ISO management systems in the UK will continue and more areas of the agriculture supply chain will feel obliged to certify their management systems to a wider range of standards than just the well known quality management and environmental management system standards. The extensive certification of ISO management systems in the UK is well known and this paper focuses on acceptance and perceptions of such standards in the UK agricultural sector. The research identified a lack of understanding and hence encourages agricultural specialists, teachers and policy makers to provide information to the agricultural sector regarding the value and scope of ISO management systems in supporting best practice and identification of regulatory compliance issues. This paper is significant in that it has acknowledged an uptake and trend in certification of management systems within the agricultural sector in the UK but has identified a lack of understanding of such systems amongst stakeholders of the agricultural supply chain. Finally, the paper clearly shows many noteworthy opportunities for further certified management systems research within the worldwide agricultural supply chain

E-learning Solutions for a Changing Global Market. An Analysis of Two Comparative Case Studies

This paper investigates the models and acceptability of e-learning to the emerging student markets for higher education institutions (HEIs) from the more developed countries (MDCs) and seeks to evaluate the differing models of delivery from a practical and a socio-economic perspective. The research also investigates the impact of the shifts in population growth and the subsequent impact upon the levels of demand from students in less developed countries (LDCs) for HE. In addition, through case study review methods the logistical and quality factors affecting e-learning are critically evaluated, looking at the aspects of academic rigor, plagiarism and the methods of managing the originality and authenticity of student work. Similarly, the research considers the viability of situations where the education provider may never physically meet the students through the exclusive use of Virtual Learning Environments (VLEs), and the possible credibility issues that this may present to institutional and awarding body reputations

Spinning Characteristics of Wings I : Rectangular Clark Y Monoplane Wing

A series of wind tunnel tests of a rectangular Clark Y wing was made with the NACA spinning balance as part of a general program of research on airplane spinning. All six components of the aerodynamic force and moment were measured throughout the range of angles of attack, angles of sideslip, and values omega b/2v likely to be attained by a spinning airplane; the results were reduced to coefficient form. It is concluded that a conventional monoplane with a rectangular Clark y wing can be made to attain spinning equilibrium throughout a wide range of angles of attack but that provision of a yawing moment coefficient of -0.02 (against the spin) by the tail, fuselage, and interferences will insure against attainment of equilibrium in a steady spin

Attitude determination through registration of earth observational imagery

With the increasing resolution of Earth observational sensors there is an increasing need for reliable, frequent and accurate attitude knowledge. Typically, high accuracy attitude systems incur large mass and costs, limiting the potential missions to which small or inexpensive satellites may apply. A neea tnererore exists tor low-mass, low-cost attitude systems capable or obtaining high accuracy attitude telemetry, especially during image capture and onboard small satellites. Towards such ends, this research investigates the potential use of a narrow stereo angle between pushbroom sensors for determining the attitude of a spacecraft.EThOS - Electronic Theses Online ServiceGBUnited Kingdo
