Income and time pressure: a person-situation grocery retail typology

A person-situation segmentation framework is proposed. The demographic variable 'income' and the situational variable 'time pressure' were integrated and applied to grocery retail shopping. Using a combination of individual scanning data and a mail survey, we divided a sample of moderate to frequent grocery shoppers in a large Belgian retail organization into four grocery-shopping segments - 'money-poor, time-rich', 'money-poor, time-poor', 'money-rich, time-rich' and 'money-rich, time-poor'. Significant differences existed between these segments in several demographic, behavioural and attitudinal characteristics, including: demographic - age, composition and size of household, number of children at home, marital status, location, education and occupation; behavioural - amount spent in the store, buying pattern for different product categories and different task definitions; attitudinal - overall attitude towards grocery shopping and different grocery-shopping attribute saliences.     

Cross-Sector Competition in Telecommunications

Cross-sector competition in the information and communications technology sectors (ICT sectors) constitutes a key strategic challenge for telecommunications companies. Due to increasing convergence, value creation is resulting in a greater degree of interaction. The diversification potential of telecommunications businesses is therefore changing with respect to associated ICT sectors, such as hardware, software and media. The article analyses cross-sector competition in the telecommunications industry on the basis of the diversification activities of ICT companies. A concentration of competitive interdependence in the ICT sectors is demonstrated using a cluster analysis of 34,142 companies. The cross-sector activities of telecommunications companies are investigated using contingency and dependency analyses, and the diversification-related competition in the telecommunications sector is also analysed. With regard to the telecommunications sector, particularly high level cross-sector competition with the media industry is identified, as well as strong diversification activities in the software sector. The results are used to derive the potentials and risks that have a significant bearing on the structure of the cross-sector competitive environment of telecommunications companies.     

An institutional evaluation of sustainable forest management in Flanders

The aim of this paper is to evaluate the existing Flemish institutional framework of sustainable forest management (SFM). The evaluation was performed using criteria and indicators that were based on the four-dimensional structure (discourse, rules, power and actors) of the policy arrangement approach. The data collection and analysis were done using a single representative case. The conclusions of the evaluation are mixed. The introduction of sustainable forest management is hampered by different perspectives on SFM and a fragmented network of many different owners with a clear asymmetrical distribution of trust and power. It is, however, enabled by the way that the most powerful and trusted actors in the network – the forest group and the forest service – have the same perspective on SFM perspective as the government. We expect that SFM can be achieved in the near future, although it remains a vulnerable situation.     

Are perks purely managerial excess?

A widespread view is that executive perks exemplify agency problems—they are a route through which managers misappropriate a firm's surplus. Accordingly, firms with high free cash flow, operating in industries with limited investment prospects, should offer more perks, and firms subject to more external monitoring should offer fewer perks. The evidence for agency as an explanation of perks is, at best, mixed. Perks are, however, offered in situations in which they enhance managerial productivity. While we cannot rule out the occasional aberration, and while we have little to say on the overall level of perks, our findings suggest that treating perks purely as managerial excess is incorrect.     

Wasserstoff als Kraftstoff im Deutschen Verkehrssektor

Hydrogen is a basic product of the (petro-)chemical industry. Furthermore it can be used as a fuel for vehicles. One main advantage of hydrogen as a fuel for drive trains is the possibility to reduce greenhouse gas emissions significantly compared to fossil fuels and avoid other local emissions. Against this background, the goal of this paper is to compare fuel cells driven by hydrogen in respect of environmental parameters. The emissions of these options are not only produced during driving and therefore this paper applies a cradle to grave approach (i.e. life cycle assessment). Greenhouse gas emissions and acidification as well as nitrogen oxides are analysed. To allow a fair comparison in total ten different systems including fossil fuels are analysed (five with hydrogen and five alternatives). That includes the entire life cycle of the car (i.e. production, use, and disposal) assuming a defined amount of kilometres to be driven during the technical lifetime. For a full assessment the energy needed to produce and run the car, the fuel production as well as the fuel distribution are considered. The results show that electrical drive trains could reduce specific greenhouse gas emissions significantly if renewable sources of energy are used. For the acidification some fossil options were better than options powered by renewable energies.     

A new class of measures of the standard of living based on functionings

Human development is about expanding the choices human beings have to lead lives that they value and is captured by its capability sets which consist of various functioning vectors. The standard of living is then reflected in capability sets. This paper proposes some particular ways of measuring the standard of living available either to an individual or a whole country, when the direction of the development of society represented by a reference functioning vector or a reference cone is uncertain. We provide axiomatic characterizations of the various measures proposed.
