Engagement in sport career transition planning enhances performance

Retirement from sport has the potential to be a major loss for professional athletes. Yet, many athletes resist engaging in career transition planning programs prior to their retirement. This research note reports the findings from an investigation on whether planning for an inevitable resource loss event (i.e., retirement from professional sport) can accrue gains (i.e., sporting performance). Data for this study was sourced from the National Rugby League, a top-level men’s professional sports league in Australasia, and included 28,516 performance selection observations for 632 players over three seasons. The findings demonstrated that higher levels of engagement in preretirement planning were positively associated with team selection, team tenure, and career tenure. Preretirement planning was also found to exert its effect on performance through the experience of career transition practitioners and the number of intervention support sessions the athletes participated in. Results are discussed in relation to conservation of resources and cognitive dissonance theories

Optimising processes of IT organisation through software products’ configuration management

The present paper is focused on the efficiency of processes within IT firms which design software products, by finding optimum management solutions for these types of activities. In order to achieve this, we focus on software products configuration management, with specific objectives in documenting and ensuring visibility to the product’s configuration and of the stage of achieving its physical and functional characteristics. Through configuration management, technical and administrative rules are established and applied for designing, developing, producing and supporting the elements of the product’s configuration, in each stage of its lifecycle. The conclusions of this research are focused on evaluating economic effects obtained by implementing the quality management system, according to the ISO 9001:2000 quality standard, while developing software products, at the level of IT firm.configuration management, quality management, product lifecycle, software quality

Generic approach for deriving reliability and maintenance requirements through consideration of in-context customer objectives

Not all implementations of reliability are equally effective at providing customer and user benefit. Random system failure with no prior warning or failure accommodation will have an immediate, usually adverse impact on operation. Nevertheless, this approach to reliability, implicit in measurements such as ‘failure rate’ and ‘MTBF’, is widely assumed without consideration of potential benefits of pro-active maintenance. Similarly, it is easy to assume that improved maintainability is always a good thing. However, maintainability is only one option available to reduce cost of ownership and reduce the impact of failure. This paper discusses a process for deriving optimised reliability and maintenance requirements through consideration of in-context customer objectives rather than a product in isolation

External technology supply and client-side innovation

Flexibility in response to competitive pressure from globalized markets and increasingly individualized customer desires has become vital for firms. A common strategy to address this challenge is to employ a dynamic concept of organization and reach beyond the boundaries of the firm. Accordingly, technology transfer from providers of knowledge intensive business services attracts more and more attention. In this context we focus on external supply of information technology and client-side innovation. The aim of this paper is to contribute to resolving an empirical puzzle arising from the prior literature. Some authors find beneficial effects of IT outsourcing, others underline that firms often fail to achieve expected strategic goals. Our stylized theoretical model combines a knowledge production function framework and transaction cost economics. We hypothesize that the right balance between internal and external knowledge is critical for innovation. The empirical application is German firm-level data covering a wide range of industries from 2003 to 2006. Our results largely support the theoretical arguments and suggest a positive linear relationship between the level of outsourcing and process innovation. For product innovation we find a hump-shape. --knowledge production function,transaction cost economics,product innovation,process innovation,KIBS,IT outsourcing,ZEW ICT survey

Understanding Digital Technology’s Evolution and the Path of Measured Productivity Growth: Present and Future in the Mirror of the Past

Three styles of explanation have been advanced by economists seeking to account for the so-called 'productivity paradox'. The coincidence of a persisting slowdown in the growth of measured total factor productivity (TFP) in the US, since the mid-1970's, with the wave of information technology (It) innovations, is said by some to be an illusion due to the mismeasurement of real output growth; by others to expose the mistaken expectations about the benefits of computerization; and by still others to reflect the amount of time, and the volume of intangible investments in 'learning', and the time required for ancillary innovations that allow the new digital technologies to be applied in ways that are reflected in measured productivity growth. This paper shows that rather than viewing these as competing hypotheses, the dynamics of the transition to a new technological and economic regime based upon a general purpose technology (GPT) should be understood to be likely to give rise to all three 'effects.' It more fully articulates and supports this thesis, which was first advanced in the 'computer and dynamo' papers by David (1990, 1991). The relevance of that historical experience is re-asserted and supported by further evidence rebutting skeptics who have argued that the diffusion of electrification and computerization have little in common. New evidence is produced about the links between IT use, mass customization, and the upward bias of output price deflators arising from the method used to 'chain in' new products prices. The measurement bias due to the exclusion of intangible investments from the scope of the official national product accounts also is examined. Further, it is argued that the development of the general-purpose PC delayed the re-organization of businesses along lines that would have more directly raised task productivity, even though the technologies yielded positive 'revenue productivity' gains for large companies. The paper concludes by indicating the emerging technical and organizational developments that are likely to deliver a sustained surge of measured TFP growth during the decades that lie immediately ahead.

The Role of Deontic Logic in the Specification of Information Systems

In this paper we discuss the role that deontic logic plays in the specification of information systems, either because constraints on the systems directly concern norms or, and even more importantly, system constraints are considered ideal but violable (so-called `soft¿ constraints).\ud To overcome the traditional problems with deontic logic (the so-called paradoxes), we first state the importance of distinguishing between ought-to-be and ought-to-do constraints and next focus on the most severe paradox, the so-called Chisholm paradox, involving contrary-to-duty norms. We present a multi-modal extension of standard deontic logic (SDL) to represent the ought-to-be version of the Chisholm set properly. For the ought-to-do variant we employ a reduction to dynamic logic, and show how the Chisholm set can be treated adequately in this setting. Finally we discuss a way of integrating both ought-to-be and ought-to-do reasoning, enabling one to draw conclusions from ought-to-be constraints to ought-to-do ones, and show by an example the use(fulness) of this
