'More is not necessarily better': the relationship between the quantity and quality of training efforts

International comparisons indicate that, on average, Belgian companies spend less on training than their French, German and Dutch counterparts. Encouraging companies to commit to training has consequently been an important policy goal over the last few years. One notable aspect of the policy to encourage training efforts by companies is that the effort is always represented in terms of the resources invested (input), not in terms of the learning achieved (output) or the quality of training programmes (throughput). Government policy is aimed at increasing the level of investment in company training. One of the questions we wish to investigate is whether this input-oriented approach to the training issue is actually effective. Whether companies will succeed in raising human capital to ever-increasing levels may depend not only (and maybe not even chiefly) on the extent of financial investment in training. The investment level does not necessarily determine the quality of the training processes developed by companies. Therefore, this paper focuses on the following research questions: (1) to what extent do companies monitor the systematic development of sufficiently effective training processes? In other words, is qualitative under-investment an issue, alongside financial under-investment? (2) Is the level of financial investment in company training correlated to the quality of training processes? The empirical data confirm that a kind of 'qualitative' under-investment can be reported and that the relationship between the level of investment in training and the quality of the training programmes is weak.     

Portfolio efficiency of a dynamic capital asset pricing model

In the present study we show that, based on equally weighted portfolios of continuously listed Finnish and Swedish stocks, aDynamic Model of Capital Asset Pricing (DCAPM) outperforms the static Capital Asset Pricing Model (CAPM) in the Super Criterion Test. It is demonstrated that the portfolio efficiency of the dynamic model is improved, when using a properly defined transition matrix in the Kalman Filtering Algorithm.The advice and encouragement of Professor Leif Nordberg (Department of Statistics, Åbo Akademi University) is gratefully acknowledged. I thank Jaana Aaltonen for her assistance in monitoring the computer programs. I also thank an anonymous referee for his valuable comments and suggestions for improving the quality of the paper.     

AN EVALUATION OF PROCESS‐ORIENTED SUPPLY CHAIN MANAGEMENT FRAMEWORKS

Supply chain management (SCM) is implemented by integrating corporate functions using business processes within and across companies. Several process‐oriented frameworks for SCM have been proposed but only two of these provide sufficient detail to enable implementation. We evaluate the Supply‐Chain Operations Reference (SCOR) framework and The Global Supply Chain Forum (GSCF) framework using four criteria and identify their relative strengths and weaknesses.     

Consistency conditions for affine term structure models

Sufficient conditions for the application of the Feynman-Kac formula for option pricing for wide classes of affine term structure models in the jump-diffusion case are derived by generalizing earlier results for bond pricing in the pure-diffusion case The author is grateful to Mikhail Chernov and Darrel Duffie for useful discussions and suggestions.     

Queue behavioural patterns for passengers at airport terminals: A machine learning approach

Passengers go through different handling processes inside airport terminal buildings. The quality of these processes is usually measured by the time passengers require and by the level of comfort experienced by them. We present an analysis of behavioural patterns in queues at check-in desks and security controls, which are two of the most critical processes regarding passenger service. The passengers' flow is simulated to obtain queue lengths at one busy European airport between 2014 and 2016, supported by real flight data. Simulation is designed as a store-and forward cell-based system, whose parameters have been tuned and validated with real data from observations and empirical capacity and demand studies within the airport. Random Forest algorithms are then implemented to develop different models for each parameter prediction, after a data analysis stage based on statistical and visualization methods. Feature analysis techniques between dependent variables and the target outputs (queue lengths) determine which are the fundamental elements to explain queue behaviour and to predict target variables. We provide a method to forecast behavioural patterns at check-in desks and security controls, to help airport operators to implement adequate response policies. Queue behavioural patterns are captured by Machine Learning models, which can be used to offer improved passenger services (such as real-time predictions for expected waiting time at queues), or can be considered in a dynamic approach for terminal services design (as the entire progress of terminal handling depends on the stochastic behaviour of passengers). This could be a key tool for managing passengers demand and optimise the infrastructure's capacity through resource allocation.

Stepping into the kitchen: lay clients as co-producers of a professional service

This study examines the implications for service organizations and their staff of clients’ involvement as co-producers of a professional service. Two female infertility clinics were analysed, one using micro-surgery (MS) and the other in-vitro fertilization (IVF) techniques. These differed on the dimension of patients’ involvement in the delivery of treatment. In the MS clinic patients were ‘passive’ recipients of treatment, whereas in the IVF clinic patients were required to partake as co-producers in the delivery of the medical service. Thus, reflected here are two different forms of client–provider interface, which the results show to have different implications. Bringing the clients, as co-producers, ‘into the kitchen’ where service is prepared (IVF) was found to involve issues associated with the lay client–professional provider work interactions, like perceptions of performance, functional work behaviour (conflicts, poor co-ordination, etc.), lower work/service satisfaction of staff and clients, and coping with service uncertainty. These and other implications for front-line service are examined and discussed.     

Social and environmental accounting,organisational change and management accounting: A processual view

Consistent with calls for in-depth studies of social and environmental accounting and reporting (SEAR) intervention (Bebbington, 2007, Fraser, 2012, Contrafatto, 2012), our paper focuses on the interrelationship between organisational change and SEAR practices, as well as the involvement of management accounting in such organisational dynamics. Drawing insight from both Laughlin (1991) and Burns and Scapens’ (2000) theoretical frameworks, we explore the processes of change through which SEAR practices become elevated to strategising status, in the context of broader organisational and extra-organisational developments, but we also illuminate how institutionalised assumptions of profit-seeking limit the extent to which broader sustainability concerns become infused into day-to-day business practice. Our paper highlights the importance of management accounting in facilitating and shaping the cumulative path of SEAR practices (and sustainability more generally); however, we also heed caution against uncritical reliance upon conventional management accounting tools. The following paper extends our understanding of SEAR practices as cumulative process over time, an awareness of the potential limits to such developments in profit-seeking organisations, and stresses a need to be circumspect when involving management accounting.     

Cognitive process differences between discrete and relational exchange

Recent research has placed greater emphasis on relational as opposed to discrete marketing exchanges. Much of this research has focused on the affective aspects of relationships. We assert that relational exchange also has a cognitive side to it. Specifically, we address two fundamental questions: (1) does a relational perspective involve different cognitive processes, which may lead to different decision outcomes? and (2) does the social context (i.e., accountability) in which decisions are made, alter decision processes and outcomes? The results of an exploratory study suggest differences in cognitive processes between discrete and relational exchange and that accountability has a strong influence on decision outcomes.
