Multinomial distributions applied to random sampling of particulate materials

When sampling a batch consisting of particulate material, the distribution of a sample estimator can be characterized using knowledge about the sample drawing process. With Bernoulli sampling, the number of particles in the sample is binomially distributed. Because this is rarely realized in practice, we propose a sampling design in which the possible samples have a nearly equal mass. Expected values and variances of the sample estimator are calculated. It is shown that the sample estimator becomes identical to the Horvitz–Thompson estimator in the case of a large batch-to-sample mass ratio and a large sample mass. Simulations and experiments were performed to test the theory. Simulations confirm that the round-off error due to the discrete nature of particles is negligible for large sample sizes. Sampling experiments were carried out with a mixture of PolyPropylene (PP) and PolyTetraFluorEthylene (PTFE) spheres suspended in a viscous medium. The measured and theoretical variations are in good agreement.     

Performance appraisal and culture: practice and attitudes in Hong Kong and Great Britain

This article compares the practice of and attitudes towards performance appraisal for managerial and professional staff in Hong Kong and Britain, and considers the extent to which actual practice and employee preferences are in alignment. Findings suggest that appraisal may be more widespread in Hong Kong than in Britain. However, British appraisal tends to be more participative and to place greater emphasis on discussing objectives, development and career plans. Hong Kong appraisals appear to be more directive and Hong Kong respondents perceive a higher level of 'negative' appraiser behaviour. In spite of this, Hong Kong respondents show if anything slightly more confidence in the utility of appraisal than do British respondents. They show stronger support for appraisal's use for reward and punishment and less support for the objectives-setting and training and development uses than do the British sample. Hong Kong respondents are more likely than their British counterparts to favour involving a more senior manager in appraisal, and they are less likely to prefer more frequent appraisals. There was little evidence that Hong Kong respondents had a stronger preference for group-based appraisal criteria, although they did show more support than the British sample for the use of personality as a basis for appraisal. Overall, the suggestion is that appraisal has been adopted in Hong Kong organizations but that the practice of appraisal has been adapted to suit the cultural characteristics of the society.     

Narrative construction of expatriate experience and career cycle: discursive patterns in Finnish stories of international

Expatriate experience is not only a disconnected occasion for cross-cultural anxiety and adjustment but also an important event in the process of self-development and learning. Following this view and arguing for a discursive approach, the paper focuses on ways in which expatriates themselves tell and interpret their development and movement across expatriate career cycle. Meaning systems connecting expatriate job with previous and following work experiences in career stories of Finnish engineers and managers were identified using a combination of narrative and discourse analysis. No evidence was found of an autonomous expatriate discourse but, in contrast, expatriate career cycle was narrated using available organizational repertoires of development and career. Describing and discussing the meaning-making properties of three identified discourses - bureaucratic, occupational and enterprising - the paper emphasizes the organizational environment of expatriate experience while acknowledging the limits of these contemporary career vocabularies in addressing individual learning and change in cross-cultural settings.     

Internet professionals: job skills for an on-line age

The paper explores the increasing popularity of the Internet technology Singapore. It argues that the diffusion of Internet technology to South-East Asia would create new duties and responsibilities for human resource (HR) managers. One such duty is the identification of the skills which professional Internet staff would need to perform their work effectively in organizations. Using a triangulation research method, empirical study has identified the new professional Internet jobs which have emerged the IT industry in Singapore and the skills that professional Internet personnel require do their jobs effectively. Analysis of the findings indicates that professional Internet skills involve both technical and creative abilities and that, in explaining or defining professional Internet skills, it is necessary to use both the technical and the social conceptions of skill. This argument is based on the view that the creative skills include tacit skills so that a definition based solely on the technical conception of skill cannot capture the various dimensions of Internet skills. The implications of the research findings for human resource managers are raised.

Sister Communities: Rejecting Labels of Informality and Peripherality in Vanuatu

Some labels have dire consequences. This article takes issue with the labels commonly used to describe the physical and social location of communities living on the edge of Port Vila, Vanuatu—labels that position communities for eviction by entrenching tropes of informality and peripherality into how they are seen and represented. Such terms include informal, settlement, informal settlement, squatter and peri-urban. Based on interviews with around 100 people and two years of ethnographic engagement with urban communities in Port Vila, Vanuatu, I critique the language of policy against the lived experience of those at the urban edge. I use Bourdieu's articulation of power as an accumulation of symbolic capital that enables one to speak the world into being. I conclude that the language of policies and plans is reflective of a dominant discourse in urban studies and international aid, and non-reflective of the experience and identities of people living at the urban edge. My interviewees and interlocutors maintain their identities as sister communities—as places grounded in the formality of customary tenure, and as part of the city rather than outside it.     

BLOCOS URBANISM: Capitalism and Modularity in the Making of Contemporary Luanda

In this article we portray and unpack the fabric of urban expansion in contemporary Luanda. In doing so, we examine interdependencies and complementarities between the organization of oil extraction off the coast of Angola, the emergence of particular modalities of modernist city planning for the expansion of its capital city, and the proliferation of cement blocks in the making of new urban forms throughout its burgeoning peripheries. By showing how urban development has unfolded through the interconnected realization of multiple kinds of systematizing blocks—namely oil blocks, city blocks and cement blocks—we analyse key material components in the production of new markets and urban spaces in the Angolan capital. By tracing forms of capitalism and modularity in the making of contemporary Luanda, we develop the concept of blocos urbanism to draw attention to modes of standardization and the production of legibility in contemporary processes of urbanization. Through this study, we aim to contribute to the conceptual apparatus for deciphering our global urban condition.     

Different Manifestations of the Concept of Empowerment: The Politics of Urban Renewal in the United States and the United Kingdom

Over the course of the 1990s the concept of empowerment became firmly established within the vocabulary of urban politics in several different national contexts. This article analyzes the spread of this concept by looking at the politics of urban renewal in the United States and the United Kingdom. It shows that even if (and possibly because) the definition of empowerment remained vague, the turn to empowerment came out of and contributed to a shift in the nature of urban politics and to a reconfiguration of governmental methods, the role of the state and, consequently, to changes in civil society, all of which were associated with a rise to prominence of a neoliberal perspective.     

Value at Risk in the Suburbs: Eminent Domain and the Geographical Politics of the US Foreclosure Crisis

Several US counties and local governments have recently considered a novel solution to the foreclosure crisis. They plan to use eminent domain to compel the owners of mortgage debt—and specifically of private‐label mortgage‐backed securities—to sell the debt to the government at a price reflecting the loan's market value. The government would then restructure the debt and resell it to new investors. The plans are striking because—in contrast to both development‐driven eminent domain and the federal subprime bank bailout—they would force investors to assume asset devaluation and increased long‐term risk. Notably, the plans have emerged as an instance of financialization‐focused politics in suburbs and suburban cities of color, specifically majority‐black and ‐Latino/a suburbs. Local support for the plans, we argue, is rooted in the long‐term disinvestment of these ‘suburbs of exception', which became targets of subprime lending and eventually sites where the ‘financial exception' has been localized. But these demographic shifts, fragmentation and fiscal pressures have at the same time created a suburban political terrain in which the plans have gained their strongest political support.     

Development in Information and Communications Technology (ICT) Statistics at the Australian Bureau of Statistics

This paper outlines the ICT statistical developments that the ABS has undertaken over recent years. These developments have been on both the supply side (ICT industry) and the demand side (use of IT by sector). The content of ABS ICT surveys has changed significantly over the last few years and are expected to develop further in line with industry changes and emerging policy needs.
Recent developments in household collections have been the inclusion of IT use questions in the 2001 Census of Population and Housing and in various ABS social surveys such as Children's Participation in Culture and Leisure Activities. Annual business IT use surveys are now conducted and include topics such as Internet commerce and IT security. Biennial ICT industry surveys are conducted to provide data on ICT production, imports and exports, ICT industry employment, performance and structure information. An Internet activity survey is run every six months and provides regional Internet access details and infrastructure details on Internet service providers.
A major development for 2002–03 will be the compilation of an ICT satellite account. ABS intends to produce an ICT Information Development Plan to guide its future statistical development work in the ICT field.
