Making explicit in design education: generic elements in the design process

In general, designing is conceived as a complex, personal, creative and open-ended skill. Performing a well-developed skill is mainly an implicit activity. In teaching, however, it is essential to make explicit. Learning a complex skill like designing is a matter of doing and becoming aware how to do it. For teachers and students therefore, it will be helpful to make the design process explicit. In this paper, a conceptual framework is developed to be more explicit about the design process. Based on research of the design process, on differences between novices and expert designers, and on personal experience in design education practice, five generic elements in the design process are distinguished: (1) experimenting or exploring and deciding, (2) guiding theme or qualities, (3) domains, (4) frame of reference or library, (5) laboratory or (visual) language. These elements are generic in the sense that they are main aspects and always present in the complex, personal, creative and open-ended design process.     

Freight train scheduling with elastic demand

A train slot selection model based on multicommodity network flow concepts is developed for determining freight train timetables for scheduling rail services along multiple interconnected routes. The model seeks to minimize operating costs incurred by carriers and delays incurred by shippers while ensuring that the schedules and demand levels are mutually consistent. A column generation-based methodology is proposed for train slot selection to meet frequency requirements. This methodology is embedded in a simulation-based iterative framework, where demand for rail services is re-computed in accordance with the train schedule obtained by solving the freight train scheduling problem.     

Estimation of Non-Stationary Social Accounting Matrix Coefficients with Supply-Side Information

Given aggregated data, a framework for estimating the entries of a social accounting matrix (SAM), or any large matrix of expenditures, trade or income flows, is developed. Under this framework it is possible to evaluate the contribution of structural and supply-side information, as well as policy variables, within the generalized context of a non-stationary SAM. Inference and diagnostic properties are developed as well. This new estimator can be viewed as a generalized maximum likelihood estimator. Stationary and non-stationary estimates of the US SAM for the years 1987-1994 together with the effects of supply-side variables are analyzed.     

Human resource differentiation: A theoretical paper integrating co‐workers' perspective and context

This paper conceptualises “human resource (HR) differentiation” as a set of deliberate and differentiating HR practices across individuals within the organisation to address employees' unique work needs and preferences as well as reward them for their input. Despite the importance of HR differentiation, research has mainly focused on the recipients of such practices, overlooking the consequences of HR differentiation from co‐workers' perspective. This is a significant omission because a growing concern suggests that HR differentiation might be a double‐edged sword, as the presumed positive effects might only be confined to employees benefiting from it. Taking a first step, this paper offers a conceptual model that explains how co‐workers of a focal employee, who is entitled to an advantageous outcome through HR differentiation, are likely to react, either positively by showing contentment or negatively by showing anger, with behavioural consequences towards the focal employee and organisation. In so doing, we rely on deontic justice theory and explore contextual conditions at the individual and team level under which co‐workers react. As a result, our model can inspire future research by adopting a broader and more inclusive approach to HR differentiation, underlining the need for caution when implementing HR differentiation in a team setting.     

Wy are the transition paths in China and Eastern Europe different?

The purpose of this paper is to provide a framework linking communist regime collapse and privatizing economic reforms. The framework permits us to explain why certain communist regimes lost their monopoly of political power while others have not. We show that the essential difference between those communist regimes which survived economic reform and those which did not, lies in the nature of the privatization reform introduced by the communist leadership. The privatization that we call ‘Market‐Leninist’, was implemented in China and Vietnam while the second type of privatization, termed ‘Embezzlement for a rainy day’ was the type of privatization implemented in Eastern Europe. We show, in the context of a game between rulers and the population, that the size of the repressive apparatus is the key element determining the type of privatization chosen by the rulers. JEL classification: P2, P3.     

The effect of monetary and fiscal credibility on public debt: empirical evidence from the Brazilian economy

This study relates to the literature regarding credibility effect on public debt for developing economies under inflation targeting. The novelty is the investigation of effects of both monetary and fiscal credibility on public debt and its management. The main idea is that high credibility might improve public debt management. With this purpose, this paper addresses empirical evidence based on the Brazilian experience. The findings denote that credibility is an important instrument to improve the public debt management under inflation targeting.
