Conflicting claims have been made in relation to the effects of polypropylene fibres on the compressive strength of concrete. The purpose of this paper is to examine the effects on compressive strength of various dosages of monofilament polypropylene fibres when used in concrete. Compressive strength is widely used as the key indicator of concrete quality and therefore needs accurate determination. Monofilament fibres and air entrainment provide a similar function in that they provide freeze/thaw protection, they are both compared against a plain concrete sample to determine relative strength and density.

Two different concrete design strengths (medium and high) were examined with varying amounts and types of polypropylene fibre fraction/volume to establish a common link between fibre additions and reduced final compressive strength.

The findings from the test programme showed a linear reduction in strength which was observed as being directly related to fibre inclusion in concrete. Density was also found to be reduced with the addition of fibres in a similar degree to that of air entrainment.

The lower density of concrete with polypropylene fibre additions was not scientifically explained and this aspect currently forms part of a long term freeze/thaw research programme, which will examine pore spacing and void formation compared to plain concrete.

This paper is of interest to clients, concrete manufacturers, concrete additive manufacturers, designers, surveyors and specifiers who need to know what effect polypropylene fibre additives have upon the final compressive strength.

The purpose of this paper is to provide guidance for designing and generating cumulative knowledge based on qualitative research.

The paper draws on the philosophy of science and specific examples of qualitative studies in accounting that have claimed a cumulative contribution to knowledge to develop a taxonomy of theoretically justified approaches to generating cumulative knowledge from qualitative research.

The paper argues for a definition of cumulative knowledge that is inclusive of anti-realist research, i.e. knowledge is cumulative if it increases the extent and density of intertextual linkages in a field. It identifies the possibility of cumulative qualitative research based on extensions to the scope of the knowledge and the depth of the knowledge. Extensions to the scope of the knowledge may include expanding the time periods, context, and/or theoretical perspective used to explore a phenomenon. Extensions to the depth of the knowledge may include new empirical knowledge, methodological pluralism, theory elaboration, or analytic generalization. Individual studies can demonstrate their contribution to cumulative knowledge by locating their research within a typology/taxonomy that makes explicit the relationship of current research to past, and potential, research.

The taxonomy may be useful to qualitative researchers designing and reporting research that will have impact on the literature.

The increased use of research impact as an evaluation metric has the potential to handicap the development qualitative research which is often thought of as generating non-cumulative knowledge. The taxonomy and the strategies for establishing cumulative impact may provide a means for this approach to research to establish its importance as a contribution to knowledge.

The concept of cumulative knowledge has not been systematically applied to research based on qualitative methods.

Points out that, although blind tests have generally revealed that consumers can detect little difference between store brand and national brand products, private brands still only have a small market share (14.9 percent). Using an environmental psychology model as the study framework, which postulates a stimulus‐response process, examines the effects of store atmosphere on consumer evaluations of private brand grocery products. Analyzes the results which show that store aesthetics do influence consumer perceptions of store brand quality. Discusses the managerial implications of the findings and the limitations of the study, and makes suggestions for future research.

THERE ARE TIMES, you know, when I feel that there is nothing new to be said about technical college libraries. Perhaps in another few years we shall have some progress to report, but, in the remote event of there being at present some development which has not been fully described, the person to do the job is probably not the librarian who is speaking to you now. He is very conscious that neither by years of experience nor by acquaintance with many different colleges is he qualified to survey technical college librarianship. Yet there may be some point in taking another look at fairly familiar territory, because some of you may have had little contact with college libraries, while others may have had relations with them different from those enjoyed by the librarian.

The aim of this study is to explore the attempts by early twentieth century cyclecar manufacturers in the UK and USA to segment the personal transportation market and to position early cyclecars through the development of unique product attributes and advertising. More specifically, the authors speculate about early twentieth century British cyclecar marketing strategies that implicitly recognized a sports car segment and positioned cyclecar brands to meet the needs of that segment.

The primary source material for this research is a sample of 205 print ads and articles from the early twentieth century (1912-1921) specialty magazines devoted to cyclecars in the UK and USA. We combine the content analysis of the sample of ads with a critical reading and interpretation of a sub-sample of those same ads.

Between 1910 and 1921, a new form of personal transportation was developed that combined the technology of motorcycles with the utility of automobiles. Known as “cyclecars”, these vehicles were typically constructed from off-the-shelf motorcycle parts and assembled in small batches by a myriad of manufacturers. Current scholarship suggests that the cyclecar craze of the 1910s ended with the introduction of low cost “real” automobiles such as the Ford Model T, Austin 7 and Morris Oxford. We use the content analysis of cyclecar advertisements to construct a brand-positioning map of this emerging segment of the transportation market. We argue that while the core cyclecar positioning was in direct competition with small economically positioned cars such as the Ford Model T, a significant part of the market, primarily centered in the UK, could be considered as for sports cars. That segment of the cyclecar market, along with the development of cyclecars into urban delivery vehicles, continued over time and has re-emerged today in a range of three-wheeled sports cars, including the updating and continuation of the British Morgan 3 Wheeler model which was launched during the heyday of cyclecars.

The authors can only speculate about the impact of the Ford Model T in this study. Further research on that issue is needed.

This is the first historical study of cyclecar marketing. Most of what little has been published about cyclecars focuses on their design and technology.

The inaugural meeting of the newly established National Party was held in the Queen's Hall, Langham Place, on Thursday, October 25th, under the presidency of Admiral Lord Beresford.

The purpose of this paper is to adopt “whole network” perspective and analyzes the governance and control mechanisms in the Universal Postal Union (UPU), one of the oldest and largest inter-governmental networks, through the lens of institutional entrepreneurship theory. The purpose is to introduce a typology of network governance forms to the accounting literature and to analyze the governance and management control mechanisms within the UPU, a “participatory federation” (Provan, 1983) type of network that has managed the challenges of collective collaboration since 1875.

The study benefits from unlimited access to all archival materials of the UPU such as minutes of Congress and committee meetings since 1875 as well as secondary documents and market studies related to the postal sector. The data reported in this study are derived from the archives of the UPU in Berne, Switzerland and interviews conducted with senior officials.

Drawing on the work of Provan (1983) and Provan and Kenis (2008) the authors identify five “ideal type” network governance forms based on such variables as differences in the relative power of network participants and whether these networks have arisen spontaneously or due to external coercion, the authors classify the UPU as a “participatory federation.” Within the theoretical boundaries of this typology the authors identify the multi level governance structures and the use of management control mechanisms by each level of governance. The authors introduce a distinction between the “network constitutional organization” that focusses on the socialization of network members and strategy-level orchestration of the overall network and the “network administrative organization” (NAO) that mobilizes management accounting and control mechanisms to monitor, encourage and facilitate member collaboration. The authors propose that control within a participatory federation is enacted through collective entrepreneurship by governance bodies using management accounting and control mechanisms as institutional carriers.

The paper is focussed on the current state of the UPU’s network structure and processes and did not explore the dynamics around the emergence of the different network governance and control mechanisms. An exploration of the collective construction by network participants of the need for these mechanisms would provide insights into how they emerge and might lead to a better understanding of the role of NAOs in networks.

The paper highlights the challenges faced by collaborative networks and identifies enabling characteristics of a participatory federation’s governance bodies. The empirical observations within the context of the UPU contribute to the theoretical understanding of the desirable characteristics of participatory federations that might be applicable to similar public and private collaborative networks

This study expands the knowledge of management accounting and control systems in networks. It bridges a gap in the accounting literature by adopting a “whole network” perspective and by differentiating types of network governance structures that use management accounting and control systems. This contributes to the understanding of accounting and control across the full range of organizational forms.

The librarian and researcher have to be able to uncover specific articles in their areas of interest. This Bibliography is designed to help. Volume IV, like Volume III, contains features to help the reader to retrieve relevant literature from MCB University Press' considerable output. Each entry within has been indexed according to author(s) and the Fifth Edition of the SCIMP/SCAMP Thesaurus. The latter thus provides a full subject index to facilitate rapid retrieval. Each article or book is assigned its own unique number and this is used in both the subject and author index. This Volume indexes 29 journals indicating the depth, coverage and expansion of MCB's portfolio.

Since the term was first coined in 1977, fractals seem to have pervaded every branch of science. Attempts to explain what fractals are and what they are being used for. Are they a fad or are they really useful? Considers factors including quantitative measurement, image compression and computer graphics. Concludes that the future will see an increase in the use of fractal graphics.

Since 1960, and especially during the past three years, many papers have appeared about particular manifestations and applications of a certain class of empirical laws to a field that may be labelled conveniently ‘Bibliometrics’. This term, resuscitated by Alan Pritchard (see page 348), denotes, in my paraphrase, quantitative treatment of the properties of recorded discourse and behaviour appertaining to it.
