Tax incentives for foreign direct investment part I : Recent trends and countertrends

According to the conventional wisdom, tax incentives for investment - in particular for foreign direct investment (FDI) - are not recommended. That is the view held almost universally by theorists and by the international bodies that advise on tax matters.' Tax incentives are bad in theory and bad in practice. They are bad in theory principally because they cause distortions: investment decisions are made that would not have been made without the inducement of special tax concessions. They are bad in practice, being both ineffective and inefficient. They are ineffective in that tax considerations are only rarely a major determinant in FDI decisions; they are inefficient because their cost, in terms of tax revenue foregone, often far exceeds any benefits they may produce. Other criticisms are also frequently levelled against tax incentives for FDI - they are inequitable (since they benefit some investors but not others), they are difficult to administer and open to abuse, and they lack transparency. Thus, it is not surprising that ''the standard advice given by institutions like the World Bank and the lMF to developing countries is to refrain from offering tax incentives to foreign investors".2 The purpose of this article is not to question that advice or to challenge the conventional wisdom - except in one respect. Recent evidence does suggest that tax considerations are an increasingly important factor in investment decisions and that special tax incentives have become substantially more effective as instruments for attracting FDI than they were 10 or 20 years ago.3 The first part of this article, published here, examines some of that evidence, reviews some recent trends in national policies towards FDI, attempts to suggest why investment incentives have become more important and more effective, and looks at the pressures that are exerted on governments, especially in developing countries, to compete for FDI by offering special incentives. The second part of the article, to be published in the Bulletin next month, assumes that many countries will continue to offer tax incentives to investors regardless of the best advice, and considers how incentives might be designed in order to increase their effectiveness and efficiency.

Mechanical behavior of irregular fibers part I : modeling the tensile behavior of linear elastic fibers

Fiber irregularities are inherent to textile fibers, natural fibers in particular. This series of papers examines the impact of fiber irregularity on the mechanical behavior of textile fibers. In the first part, the effect of fiber dimensional irregularities on the tensile behavior of linear elastic fibers is examined, using the finite element method (FEM). Fiber dimensional irregularities are simulated with sine waves of different magnitude and frequency. The results indicate that increasing the level or magnitude of irregularity will decrease the breaking load, breaking elongation and method Young’s modulus of the fiber, while increasing the frequency of irregularity will decrease the breaking load and method Young’s modulus, but the breaking elongation will increase. Fiber dimensional irregularity and the gauge length effect are also simulated in this study.

Localisation and William Macewen`s early brain surgery part I: the controversy

Neurosurgery for the removal of brain tumours based on localising signs is usually dated from the 1884 operation by Bennett and Godlee. However, within weeks of that operation claims were made on behalf of William Macewen, the Glasgow surgeon, to have been the real pioneer of such surgery. According to Macewen's protagonists, he had conducted seven similar operations earlier than Bennett and Godlee and, in a notable 1888 address, Macewen described these seven pre-1884 cases and a number of others operated on after 1884. This paper, which is in two parts, contains an evaluation of the claims made for the priority of Macewen's pre-1884 operations. Part I deals mainly with Macewen's work in fields other than brain surgery that are relevant to it and sets out the facts of the controversy. It begins with a brief biography of Macewen, describes his pioneering work in antiseptic and aseptic surgery, his work on osteotomy and bone regeneration, and his use in brain surgery of the knowledge so gained. Part I concludes with an examination of the battle waged in the newspapers between Macewen's and Bennett's and Godlee's supporters, and of previously unpublished correspondence between Macewen himself, David Ferrier and Hughes Bennett. The primary records of the patients on whom Macewen operated, together with other materials relevant to the controversy, are examined in Part II.

Guadalupian (Middle Permian) brachiopods from Sungai Toh, a Leptodus Shale locality in the Central Belt of Peninsular Malaysia. Part I: Lower Horizons

This work presents a systematic study of Permian Brachiopoda from the Sungai Toh <i>Leptodusi> Shale locality, Pahang State, Peninsular Malaysia. This locality lies within the Central Belt of Peninsular Malaysia, a tectonic unit characterised.by tuffaceous sediments and limestones of Late Palaeozoic age. Two brachiopod-bearing horizons were studied in detail at this locality, the lower one (Horizon 2) bearing a mixed plant and invertebrate assemblage, including the brachiopods <i>Urushtenoidea chaoi i>(CHING), <i>Leptodus richthofeni i>KAYSER, <i>Anidanthus i>cf.<i> sinosusi> HUANG, <i>Acosarina dorashamensis i>(SOKOLSKAJA), <i>A. minutai> (ABleH) and unidentifiable species of <i>Linoproduetusi>, <i>Neochonetesi>, and <i>Strophalosiina.i> Horizon 3 contains a more abundant and diverse brachiopod fauna, comprising a total. of 57 species representing 47 genera, including <i>Vediproductus punetatiformis i>(CHAO), <i>Permianella typicai> HE & ZHU, <i>Tranrennatia gratiosai> (WAAGEN), <i>Leptodus richthofenii> KAYSER, <i>Leptodus i>cf. <i>tenuisi> (WAAGEN) and "<i>Semibrachythyrinai>" [= <i>Alphaneospiriferi>] cf. <i>pyramidiformisi> LIANG. It is
suggested in this study that the age of the Sungai Toh locality is Capitanian (late Guadalupian) to possibly Wuchiapingian (early Lopingian),
as it appears to correlate well with the Lengwu fauna from Zhejiang in eastern China. The palaeobiogeographical affinities of the Sungai Toh fauna are interesting, mainly indicating strong Palaeo-equatorial affinities, while there are also some elements more typical of the cooler periGondwana
Region.

Twinning and the ductility of magnesium alloys Part I: “Tension” twins

Magnesium and its alloys do not in general undergo the same extended range of plasticity as their competitor structural metals. The present work is part I of a study that examines some of the roles deformation twinning might play in the phenomenon. A series of tensile test results are reported for the common wrought alloy AZ31. These data are employed in conjunction with a simple constitutive model to argue that View the MathML source twinning (which gives extension along the c-axis) can increase the uniform elongation in tensile tests. This effect appears to be similar to that seen in Ti, Zr and Cu–Si and in the so called TWIP phenomenon in steel.

Manual on application of molecular tools in aquaculture and inland fisheries management. Part I : conceptual basis of population genetic approaches

The aim of this manual is to provide a comprehensive practical tool for the generation and analysis of genetic data for subsequent application in aquatic resources management in relation to genetic stock identification in inland fisheries and aquaculture. The material only covers general background on genetics in relation to aquaculture and fisheries resource management, the techniques and relevant methods of data analysis that are commonly used to address questions relating to genetic resource characterisation and population genetic analyses. No attempt is made to include applications of genetic improvement techniques e.g. selective breeding or producing genetically modified organisms (GMOs). The manual includes two ‘stand-alone’ parts, of which this is the first volume: Part 1 – Conceptual basis of population genetic approaches: will provide a basic foundation on genetics in general, and concepts of population genetics. Issues on the choices of molecular markers and project design are also discussed. Part 2 – Laboratory protocols, data management and analysis: will provide step-by-step protocols of the most commonly used molecular genetic techniques utilised in population genetics and systematic studies. In addition, a brief discussion and explanation of how these data are managed and analysed is also included. This manual is expected to enable NACA member country personnel to be trained to undertake molecular genetic studies in their own institutions, and as such is aimed at middle and higher level technical grades. The manual can also provide useful teaching material for specialised advanced level university courses in the region and postgraduate students. The manual has gone through two development/improvement stages. The initial material was tested at a regional workshop and at the second stage feedback from participants was used to improve the contents.

Patient safety ethics and human error management in ED contexts part I : development of the global patient safety movement

In recent years there has been increasing recognition internationally that health care is not as safe as it ought to be and that patient safety outcomes need to be improved. To this end patient safety has become the focus of a world-wide endeavour aimed at reducing the incidence and impact of preventable human errors and related adverse events in health care domains. The emergency department has been identified as a significant site of preventable human errors and adverse events in the health care system, raising important questions about the nature of human error management and patient safety ethics in rapidly changing environments. In this article (the first of a two-part discussion on the subject) an overview of the incidence and impact of preventable adverse events in ED contexts is explored. The development of a ‘culture of safety’ in other hazardous industries and the ‘lessons learned’ and applied to the health care industry are also briefly examined. In a second article (to be presented as Part II), some of the ethical tensions that have arisen in the context of implementing patient safety processes and their possible implications for ED contexts are explored.

A simple displacement-based quadrilateral laminated composite plate element - part I : linear analysis

Based on the first-order shear deformation theory (FSDT) and Timoshenko's laminated composite beam functions, a simple displacement-based 4-node, 24-dof quadrilateral laminated plate element is proposed in this paper for linear analysis of thin to moderately thick laminates. The deflection and rotation functions of the element boundary are obtained from the Timoshenko's laminated composite beam functions, hence convergence to the thin plate solution can be achieved theoretically and shear-locking problem is avoided naturally. The in-plane displacement functions of a quadrilateral plane element with drilling degrees of freedom are taken as the in-plane displacements of the proposed quadrilateral element. Some numerical examples of linear analysis of composite laminated plates are calculated, and the results show that the proposed element is convergent, shear-locking free, efficient, accurate and not sensitive to mesh distortion.

A trilogy on discontinuous innovation. Part I : search

In this article we discuss the concept of Discontinuous Innovation (DI) and how it differs from incremental (or steady-state) innovation. We propose a model to conceptualise the different aspects of DI and discuss the complex nature of the DI process through an investigation of previous literature, and propose a sequence of articles roughly following the key components as described in the conceptual model, beginning with aspects of ‘search’. We then describe an on-going multi-national action research program established to investigate DI through the development of learning networks of firms in several European nations and Australia. The research progress to date is outlined and initial results of analysis on both quantitative and qualitative data collected thus far is used to explore how companies go about searching for clues or ideas about potential discontinuous innovations, which may either create competitive advantage for, or threaten the survival of the business. Key outcomes of the research to date include the identification of the most common search strategies within the participating companies and some descriptive analysis on just how these strategies are implemented in targeted firms. Finally we describe the proposed future research program and the two papers to follow completing the planned three part series on Discontinuous Innovation.

Study on the antibacterial properties of superfine wool powder part I : experiment

The superfine wool-powder was prepared by ball and jet milling. According to FZ/T 01021-92 method the bacteriostatic property of the wool-powder was tested. The results showed that wool-powder had excellent antibacterial activity against Escherichia coli (E. coli) and Staphylococcus (MRSA), and the antibacterial rate of E. coli could reach 85% and the MRSA could exceed 70%. The IR spectroscopy and X-ray diffraction analysis were used to discuss the antibacterial properties of superfine wool-powder.

Optimal sensor placement in linear arrays : part I - AoA based localization

In this paper, we examine the optimal linear separation requirements for AoA sensors, in order to achieve the best performance in estimating the position of a target subjected to noisy measurements. Cramer-Rao inequality and the corresponding Fisher information matrix are used to analyze the sensor-target geometry, in order to characterize localization performance with respect to the linear spacial distribution of sensors.
