The EMF uncertainty problem related to mobile phones: where do consumers place their trust?

This paper addresses the uncertainty problem, i.e. cases characterized by lack of knowledge or scientific uncertainty. In such situations, it can be hard for consumers to ‘voice’ or practise consumer power. One field characterized by the uncertainty problem is electromagnetic radiation. An explicit goal of this study has been to articulate Norwegian consumers' practices, attitudes and beliefs regarding electromagnetic radiation from mobile phones to public authorities and consumer policy makers. The study was based on 1000 telephone interviews collected in 2008. Today, experts disagree on the potential health effects of radiation from electromagnetic fields (EMF), as well as standards for safe limits of exposure to mobile phones, base stations and wireless telecommunication systems. In addition, complicated technology and extremely rapid product development and diffusion leave consumers' security considerations to their own beliefs and trust. Whether or not electromagnetic radiation from mobile phones constitutes a health hazard will not be addressed in this paper. Rather, it will focus on how consumers react to this situation of uncertainty. The material reveals four main ways in which consumers can solve what we have named the EMF uncertainty problem: the confident and comfortable way, the sceptical and cautious way, the responsible and good citizen way, and finally, the neglecting way. The paper also discusses the precautionary principle related to EMF. Who should be precautionary: the public authorities, the mobile phone industry or the consumers themselves? We believe that a consistent governmental precautionary policy in combination with consumers taking their own precautionary measures is a viable solution. In this way, all consumers would be addressed and aided when navigating this field of uncertainty.     

Dual materiality and knowing in petroleum production

This paper explores the relationship between materiality and knowing through the notion of dual materiality. Dual materiality highlights how digital technology becomes important, as its materiality plays an integral part in creating, not simply representing, the materiality of the physical world. We elaborate upon this insight through a theory on sociomaterial knowing grounded in ethnographic fieldwork within a petroleum company. The main theoretical proposition of this theory is that knowing arises from the emerging patterns of interaction between material phenomena, the material arrangements for knowing about these phenomena, and knowledge practices. We elaborate upon this through three predominant modes of knowing in petroleum production: instrumentation, interpretation, and learning. This paper contributes to the broader discourse on sociomateriality by refining ideas of materiality through the notion of dual materiality. We conclude by encouraging further exploration of different materialities in contemporary work and organizing.     

Wenn die Darmentleerung gestört ist

Die chronische Obstipation ist nach wie vor ein Tabu thema – auch in Kliniken und Pflegeeinrichtungen. Dabei ist das Beschwerdebild gerade in der station?ren Altenpflege sehr verbreitet und beeinflusst die Lebensqualit?t der Bewohner oft betr?chtlich. Wie ?u?ert sich das Krankheitsbild und welche Ursachen liegen ihm zu Grunde?     

The diversification cost of large,concentrated equity stakes. How big is it? Is it justified?

While the hypothesis that ownership concentration can affect the value of a company has seen a lot of empirical study, little light has been shed on a complementary problem, that these concentrated owners have a cost of their position due to an undiversified portfolio. Using a unique data set of the actual diversification of all Norwegian equity owners, we show that the largest owners of a corporation in fact have very undiversified equity portfolios, and that such owners have significant costs to their concentrated portfolios. At the level of risk of a benchmark portfolio, if they were to move from their present portfolio composition in risky assets to a well diversified portfolio, their returns would have increased by about 13 percentage points in annual terms. We ask whether this cost can be explained by estimated benefits of ownership concentration (private benefits), and show that extant estimates of private benefits are too low to offset our cost estimates.     

Slotting Allowances and Manufacturers' Retail Sales Effort

A manufacturer's incentives to undertake noncontractible investments depend on the profit margin on her sales to the retailer, and slotting allowances can facilitate such incentives by increasing unit wholesale prices. At first glance it is tempting to conclude that slotting allowances should be particularly prevalent for product categories where the manufacturer's scope for undertaking noncontractible sales effort is relatively large. At odds with this, the Federal Trade Commission (FTC) among other organizations, reports that slotting allowances are more commonly used for product categories where the scope for noncontractible effort by the manufacturer is presumably relatively small. To scrutinize this puzzle we set up a simple model with one manufacturer and one retailer, where the manufacturer undertakes noncontractible demand‐enhancing investments. The predictions from the model are consistent with market observations.     

Decentralized pricing in minimum cost spanning trees

In the minimum cost spanning tree model we consider decentralized pricing rules, i.e., rules that cover at least the efficient cost while the price charged to each user only depends upon his own connection costs. We define a canonical pricing rule and provide two axiomatic characterizations. First, the canonical pricing rule is the smallest among those that improve upon the Stand Alone bound, and are either superadditive or piece-wise linear in connection costs. Our second, direct characterization relies on two simple properties highlighting the special role of the source cost.     

The oxymoron of ‘sustainable oil production’: the case of the Norwegian oil industry

Many oil companies have adopted the concept of sustainable development and claim that their production is sustainable. This might seem odd given that the oil industry depletes a non‐renewable resource and that oil production also contributes to climate change. This paper analyses how the industry attempts to resolve this paradox, using the Norwegian oil industry as a case study. It is demonstrated how four rhetorical operations are used. By employing the topic of definition, the industry argues that it is sustainable because it (1) strives to cut its emissions and (2) manages oil resources with a long‐term perspective until such time as technology will provide solutions. The industry then uses the topic of comparison to (3) discredit other energy sources as ‘unrealistic’ options and (4) compare the production in Norway with more polluting oil production elsewhere. Understanding this type of rhetoric is crucial for validating or criticizing the sustainability claims of the industry. Copyright © 2006 John Wiley & Sons, Ltd and ERP Environment.
