TL;DR: The authors present original results for a 50 Mbit/s, 1.3 mu m wavelength digital PPM system and conclude that, provided the fibre bandwidth is several times that of the data rate,digital PPM can outperform commercially available PIN-BJT binary PCM systems.
Abstract: The abundance in bandwidth available in the best monomode fibres may be exchanged for improved receiver sensitivity by employing digital PPM. The paper presents a performance and optimisation analysis for a digital PPM coding scheme operating over a fibre channel employing a PIN-BJT receiver and assuming a Gaussian received pulse shape. The authors present original results for a 50 Mbit/s, 1.3 mu m wavelength digital PPM system and conclude that, provided the fibre bandwidth is several times that of the data rate, digital PPM can outperform commercially available PIN-BJT binary PCM systems.

TL;DR: The difference in effectiveness between the synthetic flocculants and chitosan was attributed to hydrogen bonding between polysaccharide and cell surface polymers in addition to electrostatic interactions, and, in complex media, complexation of synthetic polymers with anionic polyelectrolytes as mentioned in this paper.
Abstract: Bacteria are flocculated with high molecular weight cationic synthetic flocculants and chitosan. High charge density polymers are the most effective of the synthetic flocculants. Only chitosan is effective in flocculating the E. coli and B. subtilis cultures in complex broth. The difference in effectiveness between the synthetic flocculants and chitosan for flocculating E. coli, B. subtilis and Z. mobilis may be attributed to hydrogen bonding between the polysaccharide flocculant and cell surface polymers in addition to electrostatic interactions, and, in complex media, complexation of synthetic polymers with anionic polyelectrolytes.

TL;DR: In this paper, the authors briefly document the conventional mass housing approach deliberately adopted as a public policy in Nigeria during the period 1970-1980, and examine the consequences of the espousal and implementation of this policy option, which was based on the assumption that only the government had the instrumentalities and competence to house the masses.

TL;DR: It is argued that programming plans cannot be considered solely to be natural strategies that evolve independently of teaching nor as mere artifacts or static properties of a particular programming language, rather, such plans can be seen to be related to the expression of design-related skills.
Abstract: The notion of the programming plan as a description of one of the main types of strategy employed in the comprehension of programs is now widely accepted to form an adequate basis for an account of programming knowledge. Such plans are thought to be used universally in all programming languages by expert programmers. Recent work, however, has questioned the psychological reality of such plans and has suggested that they may be artifacts of the particular programming language used and the structure that it imposes on the programmer via the constraints of certain features of its notation. This paper considers the results of two experimental studies that suggest that the development and use of programming plans is strongly tied to the particular learning experience of the programmer. It is argued that programming plans cannot be considered solely to be natural strategies that evolve independently of teaching nor as mere artifacts or static properties of a particular programming language. Rather, such plans can be seen to be related to the expression of design-related skills. This has a number of important implications for our understanding of the nature and development of programming plans, and in particular, it appears that the notion of the programming plan provides too limited a view to adequately and straightforwardly explain the differences between novice and the expert's programming performance.

TL;DR: A survey of the opinions of UK financial managers on various issues relating to finance leases was conducted by as discussed by the authors, where the replies were analysed by various financial characteristics of the responding companies.
Abstract: The UK leasing industry has grown dramatically in the 1980s. The academic literature suggests that there are two major reasons for leasing—taxation benefits and off-balance sheet financing. Recently taxation and financial reporting changes have substantially reduced the taxation and off-balance sheet financing benefits from leasing. Against this background a postal questionnaire survey of the opinions of UK financial managers on various issues relating to finance leases was undertaken. This paper reports on the findings of the questionnaire survey. A distinguishing feature of the survey is that the replies were analysed by various financial characteristics of the responding companies.

TL;DR: In this paper, the principal properties involved in evaluating handle subjectively are identified and quantitatively described, and these properties are linked to known methods of measuring the various physical properties involved.
Abstract: The principal properties involved in evaluating handle subjectively are identified and quantitatively described. In addition, these properties are linked to known methods of measuring the various physical properties involved. A study of a small group of commercially manufactured double-jersey fabrics produced a method of recording results in the form of a polar diagram. This exercise indicated that the resulting profile could discriminate pictorially between fabrics that incorporated variations in fibres, yarn structure, fabric structure, and fabric geometry.

TL;DR: Why, asks Myrup Andreasen, has industry been so slow to take up the efforts of design science and establish systematic methodologies as part of its everyday design activity?
Abstract: SUMMARY Why, asks Myrup Andreasen, has industry been so slow to take up the efforts of design science and establish systematic methodologies as part of its everyday design activity? The answer is multifaceted but, so this paper argues, has much to do with three things. The writings on the subject lack coherence and present, to the outsider, an apparent lack of consensus. Confusion is created by the lack of an agreed vocabulary and of a taxonomy to impose order on research and other scholarly output. A suitably detailed overall systematic design methodology is not readily available. Much of this stems from the fact that design science is a relatively new discipline, even if design itself is humanity's oldest intellectual pursuit—the species survived and left a testament to its existence, by design. Solutions are suggested and in the endeavour to persuade industry of the benefits of properly designed and executed design procedures a central role is proposed for this journal.
TL;DR: 'why', 'what' and 'how' issues as they relate to the investigation of change in a nursing context, and the potential of action research in the context of bringing about change is advanced.
Abstract: This paper focuses on 'why', 'what' and 'how' issues as they relate to the investigation of change in a nursing context. The why issues revolve around the need for change, and evolutionary and revolutionary change are discussed. Next the what issues are discussed and some variables involved in the change process are identified, and the role of change agents is outlined. Change strategies such as the power-coercive, the rational-empirical and the normative-re-education are discussed. Finally, the potential of action research in the context of bringing about change is advanced.
TL;DR: An analysis of the educational role of the ward sister is considered and the extent to which her clinical and management roles inhibit her ability to effectively fulfil her educational role is considered.
TL;DR: In their recent book Relevance Lost: The Rise and Fall of Management Accounting as discussed by the authors, Johnson and Kaplan have been extremely critical of practitioners, teachers and researchers of management accounting, arguing that academic cost accountants, more than auditors or managers, may have contributed to accounting's lost relevance for cost management.
Abstract: In their recent book ( Relevance Lost: The Rise and Fall of Management Accounting ), Johnson & Kaplan have been extremely critical of practitioners, teachers and researchers of management accounting. They state that: ‘Academic cost accountants, more than auditors or managers, may have contributed to accounting's lost relevance for cost management’. This paper examines the criticisms which Johnson & Kaplan make of cost accounting systems and considers whether or not management accounting education has been one of the major factors which has contributed to these criticisms.

TL;DR: In this article, a performance and optimization analysis for a Reed-Solomon-coded n-ary PPM scheme operating over a fiber channel employing heterodyne detection and assuming a Gaussian received pulse shape is presented.
Abstract: A performance and optimization analysis for a Reed-Solomon-coded n-ary pulse-position-modulation (PPM) scheme operating over a fiber channel employing heterodyne detection and assuming a Gaussian received pulse shape is presented. Calculated results for transmission efficiency as a function of fiber bandwidth and as a function of PPM symbol size are discussed. It is concluded that the Reed-Solomon coded n-ary PPM system offers an improvement in transmission efficiency of typically 4.1 dB over an uncoded system and 11.8 dB over a heterodyne amplitude-shift-keyed pulse-code-modulated (ASK PCM) system. It is shown that a Reed-Solomon-coded n-ary PPM system can offer the same transmission efficiency as an uncoded system but at a substantially reduced bandwidth and clock rate. >
TL;DR: In this article, a single crystal X-ray structure determination of [Fe([18]aneN2S4)](BPh4) 2· 2MeCN · 1/2MeOH shows iron(II) bound to all six macrocyclic donor atoms in a distorted octahedral geometry.
TL;DR: The development of the use of objectives is discussed from its origins in the behaviourist school of thought through to the more recent approach adopted by those purporting to embrace the principles of adult education.
TL;DR: It is argued that naturalistic sociological methods such as participant observation have the greatest possibilities to describe and explain moral conduct in nursing and could better inform the debates of moral philosophers than the currently dominant sources of their case material.
Abstract: This paper argues that the current sources of material for the debate of moral questions in health care in general and nursing in particular, are inadequate The current bases of nursing's knowledge and values are explored, and the conclusion drawn that reliance upon theory developed by other disciplines has led to theories which are wholly inappropriate to explain either how nursing is practised or even how it ought to be A case is made that naturalistic sociological methods such as participant observation have the greatest possibilities to describe and explain moral conduct in nursing Further, these methods can produce a view of reality more consistent with the experiences and feelings of the patients or clients and other health workers It would seem that data and theory generated using this perspective could better inform the debates of moral philosophers than the currently dominant sources of their case material, the views of the medical and legal professions
TL;DR: In this paper, a review of various housing programmes in Libya during the first three decades of the post-independence era is presented, where the central emphasis is on the place of housing in each of the six National Development Plans from 1951 to 1980.
TL;DR: In this paper, it is argued that much greater attention should be paid to teamwork skills and the development of strategies to further multidimensional work. And it is also suggested that investigating allegations of abuse is a specialist area of practice which needs to be taught as such.
Abstract: This paper outlines the author's views on how training for competence in child protection work should be developed. It is also suggested that the ideas are of relevance for training in most areas of social work practice. In summary it is argued that much greater attention should be paid to teamwork skills and the development of strategies to further multidsciplinary work. The normal emotional reactions of professionals should be addressed and harnessed and, in training, resistances to looking at oneself and one's feelings need to be identified if students are to be engaged in such work. It is also suggested that investigating allegations of abuse is a specialist area of practice which needs to be taught as such. The author expresses some concern about how far the kind of experiential small group and individual training needed to pursue these ideas can be incorporated into CQSW courses, given the resource constraints now placed upon them.
TL;DR: In this article, a simple model based on the close relationship observed between actual evapotranspiration during the growing season and vegetation growth is presented and results from applying it to 38 sites throughout Britain are discussed.
TL;DR: In this paper, the chitosan interaction with cells, extracellular polymer and bentonite is attributed to high broth clarities, which can be attributed to chitosi-sans interaction with the cells.
Abstract: Polyelectrolyte flocculants are inefficient at flocculating Z. mobilis and B. subtilis in a complex medium, when administered singly or when combined with an oppositely charged polymer. However, when polymer dosing is followed by bentonite addition, particularly when chitosan constitutes the soluble polymer, effective flocculation occurs. High broth clarities can be attributed to chitosan interaction with cells, extracellular polymer and bentonite.
TL;DR: In this paper, the authors examine the composition of governing bodies in order to see the range of sizes adopted and how boards have been constituted within the permissible limits of the Education Reform Act 1988.
Abstract: The Education Reform Act 1988 gave independence to polytechnics and the major colleges of higher education. From a position where they were the subject of tight and bureaucratic control by the maintaining local authorities, they have moved to one where responsibility for conducting their affairs in the hands of the small group of persons who constitute their governing bodies. This paper examines the composition of governing bodies in order to see the range of sizes adopted and how boards have been constituted within the permissible limits of the Act. It also touches upon some of the difficulties and ambiguities which have been created by the present legislation. A survey reveals that most institutions have decided to have larger boards which are not dissimilar to those which existed previously and few institutions have taken advantage of the flexibility of the Act and chosen to have small boards. It remains to be seem whether size and composition have any relevance to an institution's success or otherwise in the challenging years ahead.
TL;DR: In this article, the authors explored the context in which housing activity has been undertaken in the city especially during the 1973-1975 and 1976-1980 Development Plan Periods, and found that housing investment by the Libyan State has thus intrinsically been a function of political and social, rather than economic, considerations.
