Architecture And Music

The present study deploys acoustic theory and digital analysis to investigate the dynamics of the inter-relationship of architecture and music. It assesses the impact of the built environment on music composition and performance. Drawing upon the science that underpins both architecture and music, it is also informed by the qualitative and artistic attributes of both. Reference to a specific case study, St. Patrick's Cathedral in Dublin, describes the design and implementation of a methodology designed to allow for context and era-specific assessment. The research design is interdisciplinary, bridging theory and practice. The methodology is firmly based on the use of digital technologies, which allow for efficient, accurate and replicable procedure. Data capture, analysis and mapping of the architectural site was supplemented by reference to primary archived material. Digital preservation of primary material was an integral part of the project; the resulting record created a more complete digital repository of the cathedral, combining the information which can be read in the structure itself with documents relating to its history. This article makes use of Victor Hugo's concept of the ‘Book of Stone’ to comment on the information gleaned from paper records and digital analysis of the architecture and acoustics of St Patrick's Cathedral, Dublin.

The Impact

Co-production is a solution by which the government provides public services. Co-production theory is built upon Western experience and currently focuses on the types of co-production in different policy stages, the barriers and governance strategies for co-production. However, little attention is paid to how political background will influence the co-production process. To fill the gap, we analyzed a case of co-production that occurred in China, and we characterized the political background as consisting of three main political features: political mobility, central–local relations, and performance measurement. Based on an in-depth case study of a government project in a medium-sized Chinese city, the impact and the changes of political features affecting governmental projects in different co-production stages are analyzed and assessed. We find that political features play a critical role in the co-production of China’s large government projects and may separately and jointly affect co-production. Government performance measurement affects the co-design and co-implementation of projects. Political mobility and changes in local government and performance measurement also affect the co-implementation continuity of the project. Political focus affects the co-design of projects. Central-local relations influence the support from higher government and the actual practices of lower government in the co-implementation stage.

Development Practice

Information systems development takes place within an economical context. However, the economical conditions, which shape systems development in practice, are hardly researched. In this paper we are investigating the question how a given price structure influences systems development projects. Our analysis is based on a multi case study and a Grounded Theory inspired research approach. Our work is informed by economic theories, which deal with the relationship of suppliers and customers and their mutual dependency. We thus apply principal-agent theory and economic game theory in form of the prisoner’s dilemma. As a result we provide three interlinked models for understanding the impact of pricing structure on systems development practice. The main elements of these models are pricing structure, risk distribution and price level, and opportunistic behavior. We discuss how these elements are interrelated and examine their impact on information systems development in practice.

The Relationship

A brief review of the state of music education in the UK at the time of the creation of the British Journal of Music Education (BJME) leads to a consideration of the range and focus of topics since the initiation of the Journal. In particular, the initial requirement of careful and critical enquiry is amplified, drawing out the inevitability of theorising, an activity which is considered to be essential for reflective practice. The relationship of theory and data is examined, in particular differentiating between the sciences and the arts. A ‘case study’ of theorising is presented and examined in some detail and possible strands of future development are identified.

The Impact

Research suggests, according to Branch, Ramsay, and Barker (2013), that a significant number of people are exposed to persistent abusive treatment within the workplace, with the majority of studies within Europe indicating that between 10% and 15% of the workforce are exposed to workplace bullying (Zapf, Escartin, Einarsen, Hoel, & Vartia, 2011), with North American research reporting similar prevalence rates. This is a significant, ongoing dilemma for researchers and practitioners, for which an agreed resolution would be useful because of legal and policy implications. Hence, the purpose of this chapter is on the impact of organizational trauma on workplace behavior and performance based on workplace bullying. The chapter is based on a case study regarding a program that is funded by the Department of Education within a community college in the State of California. The community college is one of four community colleges under the same community college district.

Manufacturing Readiness

This chapter aims to provide a new readiness matrix called ‘innovative manufacturing readiness levels (IMRLs)’ to evaluate and assess the areas of micro and nanotechnology maturity including their performance. The study employs a case study approach through which the practicability and applicability of the IMRLs conceptual matrix were verified and confirmed. A case study with laser-based manufacturing technologies explores the stages of micro and nano technologies (MNTs)’ maturity, including the key issues and performances that contributed to the development of a new assessment tool. Concerning intense global R&D competition in MNTs, this study exhibits a forward-looking approach in assessing MNTs maturity and performance. A generic conclusion is reached by which product designers and technology managers position themselves and take into account risk reduction exercises related to MNTs. The novelty of the research could be that organizations, which develop and use MNTs, have an opportunity in applying such a specific assessment matrix to quantify the technology readiness of unreleased MNTs.

The Impact

Direct Drive Open Rotors (DDORs) have the potential to significantly reduce fuel consumption and emissions relative to conventional turbofans. However, this engine architecture presents many design and operational challenges both at engine and aircraft level. At preliminary design stages, a broad design space exploration is required to identify potential optimum design regions and to understand the main trade offs of this novel engine architecture. These assessments may also aid the development process when compromises need to be performed as a consequence of design, operational or regulatory constraints. Design space exploration assessments are done with 0-D or 1-D models for computational purposes. These simplified 0-D and 1-D models have to capture the impact of the independent variation of the main design and control variables of the engine. Historically, it appears that for preliminary design studies of DDORs, Counter Rotating Turbines (CRTs) have been modelled as conventional turbines and therefore it was not possible to assess the impact of the variation of the number of stages (Nb) of the CRT and rotational speed of the propellers. Additionally, no preliminary design methodology for CRTs was found in the public domain. Part I of this two-part publication proposes a 1-D preliminary design methodology for DDOR CRTs which allows an independent definition of both parts of the CRT. A method for calculating the off-design performance of a known CRT design is also described. In Part II, a 0-D design point efficiency calculation for CRTs is proposed and verified with the 1-D methods. The 1-D and 0-D CRT models were used in an engine control and design space exploration case study of a DDOR with a 4.26m diameter an 10% clipped propeller for a 160 PAX aircraft. For this application: • the design and performance of a 20 stage CRT rotating at 860 rpm (both drums) obtained with the 1-D methods is presented. • differently from geared open rotors, negligible cruise fuel savings can be achieved by an advanced propeller control. • for rotational speeds between 750 and 880 rpm (relatively low speeds for reduced noise), 22 and 20 stages CRTs are required. • engine weight can be kept constant for different design rotational speeds by using the minimum required Nb. • for any target engine weight, TOC and cruise SFC are reduced by reducing the rotational speeds and increasing Nb (also favourable for reducing CRP noise). However additional CRT stages increase engine drag, mechanical complexity and cost.

The Impact

Of the many factors that contribute to communication performance, perhaps one of the least investigated is that of message-buffer alignment. Although the generally accepted practice is to page-align buffer memory for best performance, our studies show that the actual relationship of buffer alignment to communication performance cannot be expressed with such a simple formula. This paper presents a case study in which porting a simple network performance test from one language to another resulted in a large performance discrepancy even though both versions of the code consist primarily of calls to messaging-layer functions. Careful analysis of the two code versions revealed that the discrepancy relates to the alignment in memory of the message buffers. Further investigation revealed some surprising results about the impact of message-buffer alignment on communication performance: (1) different networks and node architectures prefer different buffer alignments; (2) page-aligned memory does not always give the best possible performance, and, in some cases, actually yields the worst possible performance; and, (3) on some systems, the most significant factor affecting network performance is the relative alignment of send and receive buffers with respect to each other.

Purpose The purpose of this paper is to examine the impact of organizational culture on open government reforms by developing a theoretical framework bridging the theory and practice gap. Design/methodology/approach An exploratory qualitative study consisting of a document analysis and a case study was conducted. Findings An open organizational culture is a precursor to effective open government. A network strategy as a facilitator for developing an open culture was used in one US federal agency, breaking across boundaries within the organization, creating greater symmetrical horizontal and vertical openness. Originality/value Much of the focus in both theory and practice has been on the use of technology as a vehicle to increase government openness. This study argues that a movement toward openness is beyond the technical. Organizational culture is a key to openness and may need to be changed. A networks strategy may be one way to facilitate a transformation to a more open culture.

The Impact

This article draws on in-depth qualitative interviews with ten practitioners who specialise in working with young carers, to examine how members of the emerging profession of ‘young carers’ worker’ view their partnerships with social services. It focuses particularly on one case study area (Town Z), where partnerships between social services and the voluntary sector around young carers were relatively highly developed. It explores the practitioners’ comments about the impact of their organisations’ partnerships with social services on their work. This is done in the context of their conceptualisations of care and family relationships. In particular, the themes of identifying young carers and working with the family as a whole are discussed, and young carers’ workers views are compared to the conceptualisations that come across in literature from both disability studies and social work perspectives. It is concluded that young carers’ workers conceptualisations of care and disability do differ markedly from the perspectives that appear to dominate both social work theory and practice, and that this impacting on how the former view their partnerships with the latter.

This paper proposes a new method of collaboration within a team of twoindividual NAO robots that should execute together a complex operation. The Naorobots are developed so as not only to act individually, but also to cooperatewith other robots if they cannot accomplish the operation alone. This paperpresents a case study demonstrating the integration of the humanoid roboticsplatform Nao within a cooperation application. This specific scenario ofinterest takes place in a small simulated manufacturing environment; while thetask being the storage of a big object, with different shape and weight. Thisscenario is used to observe the impact and performance that this particularteam of humanoid robots has in an industrial environment.Finally we present the successful implementation of robot – robot cooperationcapabilities inspired by human behaviour.
