Conditionally heteroscedastic intensity‐dependent marking of log Gaussian Cox processes

Spatial marked point processes are models for systems of points which are randomly distributed in space and provided with measured quantities called marks. This study deals with marking, that is methods of constructing marked point processes from unmarked ones. The focus is density‐dependent marking where the local point intensity affects the mark distribution. This study develops new markings for log Gaussian Cox processes. In these markings, both the mean and variance of the mark distribution depend on the local intensity. The mean, variance and mark correlation properties are presented for the new markings, and a Bayesian estimation procedure is suggested for statistical inference. The performance of the new approach is studied by means of simulation experiments. As an example, a tropical rainforest data is modelled.     

Learning in the process of industrial work – a comparative study of Finland,Sweden and Germany

By combining a positivistic and an interpretive approach, this research investigates the learning opportunities that contemporary industrial work processes and workplaces offer for employees individually and collectively. The research explores how employees can become trained through their work and how individual development may expand to collective development. Finnish and Swedish package‐supplier companies have served as case‐study organizations, and the findings from them have been benchmarked to the available corresponding German data. The results show that although employees may have opportunities for individual learning in enriched, enlarged and autonomous manufacturing work, the prevailing bureaucratic power relations prevent employees from fully engaging in collective learning. It is concluded that a positivistic research approach and a sociotechnical theoretical framework make visible the training through work taking place at the individual level, while an interpretive research approach and concepts from complexity thinking reveal the obstacles to collective learning.     

The Consequences of Globalisation: India's Software Industry and Cross‐border Labour Mobility1

The Indian software industry is a prime example of globalisation. The industry has been characterised by large cross‐border mobility of its skilled labour force. Using a unique survey of Indian software firms, our paper quantifies the extent and impact of mobility on firm behaviour and performance. Cross‐border labour mobility in the paper refers to both temporary and permanent labour flows by Indian software professionals. The picture that emerges is of a highly mobile world in which temporary mobility has been an important characteristic of the industry. A significant number of workers have work experience abroad in a developed country. Moreover, the share of skilled workers with such experience has been positively associated with the incidence of skilled migration from the firm. This suggests network effects are at work. In terms of the impact on performance – as measured by the change in turnover per worker and the change in the employment size of the firm – the paper finds little evidence of a robust adverse effect. Further, the evidence suggests that there have been important external effects at work, as through changes in the willingness of workers to acquire skills, as well as through increased provision of educational services. These have further abated the risk of a brain drain. However, the software industry may be rather different from other industries. Our results need to be interpreted as the outcome of a particular case of skilled migration and not one necessarily representative of all types of skilled migration and source sectors.     

Tourism,business linkages and small enterprise development in South Africa

Although considerable attention is given to the prospects for developing small, medium and micro-enterprises (SMMEs) in South Africa's tourism economy, very little relevant research has been undertaken in this regard. In this article, the findings are presented from over 60 detailed interviews conducted with key enterprises and entrepreneurs involved in tourism, outsourcing and small enterprise development in South Africa. The aim is to examine opportunities for outsourcing and business linkage development in South Africa's tourism economy, and to investigate the difficulties that confront the tourism SMME economy through examining the status of business linkages between large tourism enterprises and SMMEs in South Africa. The South African research is located within the context of existing works on tourism and small enterprise development in developing countries.     

Institutional Aspects of Youth Employment and Training Policy: A Comment on Marsden and Ryan

This Comment questions the reasons why Marsden and Ryan (1990) have come to favour prescribing apprenticeship and occupational markets for reviving training in Britain. Their assessment failed to take account of (a) other advantages of internal labour markets over occupational markets, (b) institutions other than those in labour markets, and (c) training features common in well functioning occupational and internal markets as revealed by a comparison of Germany and Japan. The examination of these factors casts a doubt on the feasibility and desirability of Marsden and Ryan's policy recommendation.     

A methodology for cluster analysis of citation histories

Citations to all the papers (558) published from 1955 to 1964 by a multidisciplinary (natural sciences) research institute within a ‘scientific periphery’ were collected for the 11-year period after a 10-year lapse since the publication years. All the papers were grouped into 31 research topics, three of which had no such late citations at all. For the remaining 28 groups of papers three indicators were defined: ALPHA, the ratio of the number of papers with citations, to the number of all papers of the particular research topic, indicating thus an overall CITATION EFFICACY; BETA, the ratio of the sum of all citations, to the number of the cited papers, indicating CITATION INTENSITY, and GAMMA, expressing the CITATION LONGEVITY for a given research topic as the incidence (number) of cited papers (irrespective of the number of citations) within the 11-year citing period. In addition, three normalized transformations of the indicator BETA were checked. Two-dimensional (without ALPHA) and three dimensional (with ALPHA, GAMMA, and one of the BETA variants) graphical representations together with a pairwise correlation analysis served as preliminary guidance in the latter statistical analyses by (a) Ward's Hierarchical Cluster Analysis and (b) Polar Taxons Analysis. Both of them resulted in good agreement. Thus, the 28 research topics were found to belong to three clusters. Their composition varied slightly for the original BETA and its three normalized values. It was concluded that ALPHA is not a redundant but quite useful indicator, and that one of the normalized BETA-variants appears most suitable for this kind of studies. In the three-dimensional graphs the clusters may be related to scientific merit as judged in a composite way by all the three indicators. This is done with regard to the diagonal joining the indicators' maximal with their minimal values. The citation LONGEVITY (GAMMA) appears to be most important. Cluster stability tests showed fluctuations of few research topics, which was related to their specific features within the given research setting. It emerges on the whole that the research merit of this (peripheral) scientific production is determined neither by the journals status the papers were published in, nor by the authors' institutional status. Rather, it is the very scientific quality of individual papers within a given research topic that is decisive for the citation ‘survival’.     

Mobile banking and consumer behaviour: New insights into the diffusion pattern

Technological advancement has challenged the providers of financial services; the very nature of selling and buying financial services has changed. Mobile devices are among the newest channels to conduct banking electronically. This paper focuses on studying diffusion and adopters of mobile banking services. Previous research has identified the typical characteristics of a potential adopter in the electronic services era; this paper explores some contradictory empirical findings drawn from a mobile banking survey. The results provide an indication of the characteristics of potential subsequent adopters of mobile banking, and of differences between user segments. Consequently, the authors are able to comment on the influence of certain demographic characteristics and the preferred communication mode of customers on the adoption and future usage of mobile banking services. The quantitative survey that sheds more light on this researched issue employed a traditional method of postal questionnaire. The data were collected in Finland during May–July 2002 and include 1,253 survey responses.     

Exploring service design in the context of architecture

Development of services is a demanding task and requires new perspectives as well as appropriate tools and techniques. This paper forms an overview of the concept of service design, which has recently gained ground. This concept is applied to an empirical study, which explores how professional designers develop services. The main method of the study is participant observation taking place in an architect's office. As a result, the study describes in detail how services are designed in the context of architecture. The study suggests that professional designers apply several methods, which could increase our understanding of service design and service development.     

Ethical Organisational Culture as a Context for Managers’ Personal Work Goals

The aims of this study were to investigate what kinds of personal work goals managers have and whether ethical organisational culture is related to these goals. The sample consisted of 811 Finnish managers from different organisations, in middle and upper management levels, aged 25–68 years. Eight work-related goal content categories were found based on the managers self-reported goals: (1) organisational goals (35.4 %), (2) competence goals (26.1 %), (3) well-being goals (12.1 %), (4) career-ending goals (7.3 %), (5) progression goals (6.8 %), (6) prestige/influence goals (4.2 %), (7) job change goals (4.2 %) and (8) employment contract goals (3.9 %). Ethical organisational culture operated as a context for personal goal setting: Those managers who evaluated their organisational culture as more ethical were more likely to report organisational goals (e.g. goals toward the success or performance of the organisation). However, if managers gave lower ratings regarding ethical culture, then they named job change and career-ending goals in more cases. Therefore, investing into ethical virtues of the organisational culture can promote managers’ personal work goals, which also benefit the organisation.
