Focusing on Johannes L. Sadie, a South African economist hired to investigate the economic options of Southern Rhodesia at the time of the Unilateral Declaration of Independence (UDI), this chapter examines the historical, ideological, pedagogical, and international influences of the intersection between economic discourse and racial ideology. Using the example of the Sadie recommendations, this chapter examines how the changing political context informed the state’s approach to the economy. A reading of the context in which Sadie was hired to justify Rhodesia’s UDI and provide legitimacy to its economic policies sheds light onto the Ian Smith regime’s approach to an alternative post-imperial (but not post-settler) state and economy, but it also speaks of the ways in which economic discourse can be deployed for political purposes by authoritarian regimes.

The aim of this publication is to list the catalogues of the Department of Manuscripts which are in regular use. Catalogues which have been superseded by later publications are not normally included, since whatever their historical or bibliographical interest they are no longer everyday working tools. To save space in cross‐reference, the catalogues, etc., here listed have been numbered serially in Clarendon type, thus: 31. This numeration has no other significance.

For the laser powder bed fusion (L-PBF) technology, the side surface quality is essentially important for industrial applicated parts, such as the inner flow parts. Contour is generally adopted at the parts’ outline to enhance the side surface quality. However, the side surface roughness (Ra) is still larger than 10 microns even with contour in previous studies. The purpose of this paper is to study the influence of contour process parameters, laser power and scanning velocity on the side surface quality of the AlSi10Mg sample.

Using L-PBF technology to manufacture AlSi10Mg samples under different contour process parameters, use a laser confocal microscope to capture the surface information of the samples, and obtain the surface roughness Ra and the maximum surface height Rz of each sample after analysis and processing.

The results show that the side surface roughness decreases with the increase of the laser power at the fixed scanning velocity of 1,000 mm/s, the side surface roughness Ra stays within the error range as the contour velocity increases. It is found that the Ra increases with the scanning velocity increasing and the greater the laser power with the greater Ra increases when the laser power of contour process parameters is 300 W, 350 W and 400 W. The Rz maintain growth with the contour scanning velocity increasing at constant laser power. The continuous uniform contour covers the pores in the molten pool of the sample edge and thus increase the density of the sample. Two mechanisms named “Active adhesion” and “Passive adhesion” cause sticky powder.

Formation of a uniform and even contour track is key to obtain the good side surface quality. The side surface quality is determined by the uniformity and stability of the contour track when the layer thickness is fixed. These research results can provide helpful guidance to improve the surface quality of L-PBF manufactured parts.

The purpose of this research paper is to provide corporate real estate executives with a measurement tool for pinpointing and enhancing the contribution of corporate real estate to corporate strategy.

A measurement tool is designed by adopting a theoretical framework in which seven added values of real estate are aligned with nine corporate strategic driving forces. The practical applicability of this tool is validated by assessing the contribution of corporate real estate to corporate strategy at 14 Dutch‐based global corporations.

Many corporations still lack sufficient insight into the impact of corporate real estate decisions on corporate performance. Therefore, it is difficult for senior management and other stakeholders to grasp the actual contribution of corporate real estate.

Future research may be conducted to investigate the exhaustiveness of the listed real estate issues. Moreover, the linkage between the added values and the strategic driving forces could be validated further in practice.

The measurement tool supports corporate real estate executives in aligning corporate real estate with corporate strategy. Thereby it contributes to the further recognition of the importance of real estate in a corporate setting.

Prior papers on the contribution of corporate real estate to corporate strategy have primarily been focused on either pinpointing various driving forces or linking specific property decisions to corporate strategy. This paper, however, unveils the linkage between fundamental drivers of corporate real estate and corporate strategy in a comprehensive management tool for portfolio analysis and strategy formulation.

This study aims to evaluate the property tax base under the local government property taxation in Nairobi City and its implication on revenue adequacy of the city. Nairobi has grown both in population and in physical extent resulting to increased demand for urban services. The city faces challenges of adequate infrastructure service provision against increasing demand. Property taxation if fully exploited can be a major source of city government revenue, which has been dwindling.

Literature review of property tax bases in the world and examination of best practices was done to highlight the inadequacies of property tax base administration in Nairobi. Primary data were gathered through interviews of officers in Nairobi City involved in the land rating process. Secondary data were obtained through documentary search and field survey of the study area.

The study established that Nairobi relies on a dual system of taxation, namely, site value rating and area rating. Tax is on vacant land only and excludes improvements. There are many legal exemptions and administrative exclusions from the tax base. The property tax registers do not include all the taxable properties and there is no regular updating of the tax registers. Nairobi relies on an outdated valuation roll whose values have no relation to the current market values.

These factors have resulted to a narrow tax base, which affects the revenue potential of the city and its ability to adequately provide infrastructure services.

This is an original research, which relied mainly on primary data. To establish the property tax bases and the exempt properties in Nairobi, the researchers interviewed the officers at the Nairobi city land valuation and property management directorate using structured questionnaires. To address the third objective on whether the property tax base is complete and all-inclusive, the research relied on primary data. The research population was residential properties in Buruburu, Kilimani and Riruta areas of Nairobi city. The sample data on property details were collected from the Ministry of Land and Physical Planning (MLPP). The researchers then examined the records at the Nairobi City to evaluate whether the properties, which are registered at the MLPP, are charged land rates at the city level and at what amounts. This included properties under site value rating and area rating.

DEUTSCH Entzinkung von Messing. Cu/Zn‐Legierungen werden unter bestimmten Bedingungen in einer als ‘Entzinkung’ bezeichneten Form angegriffen. Wie der Ausdruck besagt, geht Zink aus der Legierung in Lösung, so dass Kupfer in Form einer porösen Masse zurückbleibt, die nur geringe oder überhaupt keine Festigkeit mehr aufweist. Da Korrosion ein Oberflächenvorgang ist, beginnt auch die Entzinkung an der Ober‐ fläche und dringt allmählich ins Innere des Metalls vor, bis entweder Undichtigkeiten oder Risse das betreffende Werkstück unbrauchbar machen. Entzinkung trifft man häufig in Messingteilen, die mit chloridhaltigem Wasser in Berührung stehen. Der Verfasser beschreibt in der vorliegenden Arbeit einschlägige Untersuchungen, die an der Universität Witwatersrand in Johannesburg (Südafrika) durchgeführt wurden. Seite 11

The humanitarian supply chain (HSC) area is rich with conceptual frameworks with a focus on the importance of information and digital technology (IDT) applications. These frameworks have a limited scope in investigating and prioritizing barriers to IDT adoption in HSCs. The present study thus identifies and prioritizes the barriers to IDT adoption in organizations involved in HSCs.

By using a literature review allied with expert discussions and a fuzzy analytic hierarchy process (F-AHP), the study identifies and prioritizes a comprehensive set of barriers that organizations involved in HSCs may consider to improve IDT adoption.

The study investigates five main barriers (strategic, organizational, technological, financial and human) interlocked with 25 sub-barriers impacting the level of IDT adoption in organizations involved in HSCs. The findings indicate that strategic barriers (SBs) are of greatest importance, followed by organizational, technological, financial and human barriers. The findings indicate the difference in ranking barriers influencing the adoption of IDTs in HSCs compared to the commercial supply chain.

Although a three-step method adopted for this study is rigorous in terms of the way this research is conducted, it is essential to report that prioritization is based on the subjective opinions of the experts.

The findings aim to assist policymakers and practitioners in developing effective strategies to improve IDT adoption in organizations engaged in HSCs. Moreover, the prioritization of barriers provides a systematic way to overcome any barriers to improve HSC performance.

This study is first of its kind that investigates and prioritizes the barriers to IDT adoption in HSCs.

The purpose of this study is to refine the microstructure and improve the corrosion behaviour of aluminium alloy AA5083 by subjecting it to friction stir processing (FSP).

FSP trials are conducted as per central composite design, by varying tool rotation speed, tool traverse speed and shoulder diameter at three levels. The microstructure is examined and the hardness is measured for both the base material and the processed workpieces. The corrosion behaviour of the base material and processed workpieces is studied using potentiodynamic polarization technique for three different testing temperatures, and the corrosion current and corrosion rate are calculated.

The results reveal that FSP refined the grains, dispersed secondary phases, increased the hardness and improved the corrosion resistance of most of the friction stir processed specimens than the base material at all the three testing temperatures. Grain refinement and fine dispersion of ß phase improves the hardness and corrosion resistance of most of the FSPed specimens. However partial dissolution of ß phase decreases the hardness in some of the specimens. Most of the FSPed specimens displayed more positive potential than the base material at all the testing temperatures representing a higher nobility than the base material, as a result of fine dispersion of secondary phase particles in the matrix. Large pits formed on the surface of the base specimen indicating a higher corrosion rate at all three testing temperatures. The SEM image of FSPed specimens reveals the occurrence of very few pits and minimal corrosion products on the surface, which indicates lower corrosion rate.

The corrosion mechanism of the friction stir-processed AA5083 specimens is found to be a combination of activation and concentration polarization.

Conventional theories suggest that the Internet will drive down prices and lead to perfectly competitive prices. However, there is contradictory evidence indicating that online prices are not absolutely lower than offline stores. Regardless, the Internet gives rise to many opportunities for leveraging pricing strategies, in research and testing capabilities, customer segmentation, dynamic pricing, product differentiation, developing brand loyalty, including shipping and handling in the profitability analysis, offering multiple versions, and creating or participating in electronic marketplaces. The trading platform of eBay, Priceline’s reverse auction, and price comparison Web sites are examples of novel Internet pricing models that are helping create a new pricing paradigm.
