Abstract
This paper is concerned with outlining the role of ‘communication’ and ‘measurement’ techniques in the successful achievement of one of the longest and most complex financial re‐structurings undertaken in commercial history. It sets out the background of a financial crisis which deepened and threatened to overwhelm Lloyd's, a three‐centuries‐old financial institution whose name is synonymous with ‘insurance’. This paper is based on an original presentation to the Insurance Institute of London in November 1996 entitled, ‘Lloyd's PR Under Siege’. It outlines some of the many difficulties faced in securing a successful resolution to a complex problem which had a worldwide dimension, from which important lessons can be drawn for ‘crisis management’ applied within organisations. In particular, reference will be made to the role played by quantitative and qualitative ‘attitudinal research’ among key audiences and to the deployment of ‘media evaluation’ techniques in support of communications objectives.

Abstract
Purpose
This paper aims to investigate the deposited structure and mechanical performance of printed materials obtained during initial development of the Big Area Additive Manufacturing (BAAM) system at Oak Ridge National Laboratory. Issues unique to large-scale polymer deposition are identified and presented to reduce the learning curve for the development of similar systems.
Design/methodology/approach
Although the BAAM’s individual extruded bead is 10-20× larger (∼9 mm) than the typical small-scale systems, the overall characteristics of the deposited material are very similar. This study relates the structure of BAAM materials to the material composition, deposition parameters and resulting mechanical performance.
Findings
Materials investigated during initial trials are suitable for stiffness-limited applications. The strength of printed materials can be significantly reduced by voids and imperfect fusion between layers. Deposited material was found to have voids between adjacent beads and micro-porosity within a given bead. Failure generally occurs at interfaces between adjacent beads and successive layers, indicating imperfect contact area and polymer fusion.
Practical implications
The incorporation of second-phase reinforcement in printed materials can significantly improve stiffness but can result in notable anisotropy that needs to be accounted for in the design of BAAM-printed structures.
Originality/value
This initial evaluation of BAAM-deposited structures and mechanical performance will guide the current research effort for improving interlaminar strength and process control.

Abstract
Sir Peter Parker has been a leading British figure in management, in management education and development for many years. In this conversation with Bruce Lloyd, Sir Peter reflects on the social, political, economic and international context of management and organizational development. His gentle, sometimes understated, commentary, masks a restless energy and an enthusiasm for change.

Abstract
Propósito
La presente investigación examina la existencia de memoria de largo plazo por medio del cálculo del coeficiente de Hurst y Hurst ajustado, y del análisis de características de estructuras caóticas en la serie del mercado bursátil de Chile, específicamente a través del Índice de Precios Selectivo de Acciones.
Diseño/metodología/enfoque
Se desarrolló un breve análisis del mercado, según la metodología de Box y Jenkings. La validez de los resultados se realizó por medio de la prueba propuesta por Brock, Dechert y Scheinkman. En segundo lugar, se procedió a analizar la dinámica y patrones del índice y de su rendimiento, para observar si existía evidencia de memoria de largo plazo.
Hallazgos
Los resultados demuestran la presencia de esta memoria en el mercado bursátil chileno, determinado a través del índice accionario en dos escalas, diaria y trimestral, lo que además corrobora resultados obtenidos por otros autores, confirmando el uso de la metodología de Rango Re-escaldo para la identificación y determinación de memoria de largo plazo en una serie temporal.
Originalidad/valor
Este estudio permitirá a futuros investigadores realizar análisis similares en otros mercados, aportando un nuevo enfoque al analizar la memoria de la largo plazo y los factores que inciden en ella.

Purpose
This research examined the existence of long-term memory by calculating the coefficient of Hurst and Hurst set, and the analysis of characteristics of chaotic structures in the series of stock market of Chile, specifically through the Selective Price Index Shares.
Design/methodology/approach
A brief analysis of the market was developed, according to Box and Jenkins methodology. The validity of the results was performed by means of the test proposed by Brock, Dechert and Scheinkman. Secondly, we proceeded to analyze the dynamics and patterns of the index and its performance, to see if there was evidence of long-term memory.
Findings
The results demonstrate the presence of long-term memory in the Chilean stock market, determined by stock index in two scales, daily and quarterly, which also corroborates results obtained by other authors, confirming the use of the methodology Range Re-scalded for the identification and determination of long-term memory in a time series.
Originality/value
This study will allow future researchers to perform similar analyzes in other markets, providing a new approach when analyzing the long-term memory and the factors that affect it.

Abstract
British government approves data network After months of preparation by HM Treasury's Central Computer and Telecommunications Agency (CCTA), the first phase of the Government Data Network (GDN) has now been accepted. Trials of GDN took place in January, and it has now been implemented for daily use in 178 Customs and Excise locations throughout Britain. GDN is operated by Racal Data Networks.

Abstract
In the last four years, since Volume I of this Bibliography first appeared, there has been an explosion of literature in all the main functional areas of business. This wealth of material poses problems for the researcher in management studies — and, of course, for the librarian: uncovering what has been written in any one area is not an easy task. This volume aims to help the librarian and the researcher overcome some of the immediate problems of identification of material. It is an annotated bibliography of management, drawing on the wide variety of literature produced by MCB University Press. Over the last four years, MCB University Press has produced an extensive range of books and serial publications covering most of the established and many of the developing areas of management. This volume, in conjunction with Volume I, provides a guide to all the material published so far.

Abstract
Purpose
The purpose of this paper is to present an overview of the development process and outcomes from a six-year collaboration between Halifax Bank (part of the Lloyds Banking Group) and Middlesex University between 2010 and 2016 in the UK. The collaboration involved the construction of work-integrated higher education programmes that were, from the outset, predicated on clear return on investment criteria for the Bank. One unexpected outcome from the collaboration was the emergence of critical reflection as a valued business benefit that, it is argued, has the potential for significant cultural change within the organisation.
Design/methodology/approach
This case study discuses how “productive reflection” can lead to an integrated approach to organisational learning. The study is located in the context of Halifax’s specific organisational objectives established following the banking crash of 2008. Quantitative and qualitative evidence is considered to illustrate the extent to which the “return on investment” criteria established by Halifax have been achieved.
Findings
The case study indicates that the challenging business context of the financial crash of 2008 provided the impetus for a sustained collaborative development that allowed the potential pitfalls of restricted learning opportunities to be addressed resulting in an integrated approach to organisational learning. In addition to the organisation’s return on investment criteria being met, there is evidence that the work-integrated approach has raised the prospect of productive reflection becoming part of an emerging learning culture.
Originality/value
The scale and sustained period of the university-business collaboration is unique and provides valuable insight into how an organisation’s learning culture can be affected by a work-integrated approach. In demonstrating the perceived business value of productive reflection, the case presented illustrates how learning can start to become considered as a normal aspect of working life.
