Journalists’ Coverage of Online Firestorms in German-Language News Media
2016
When people perceive events that conflict with their expectations they can easily express their agitation and concerns online and likely find others who share their opinion. When large quantities of messages containing negative word-of-mouth suddenly spread in social media we speak of an online firestorm. By covering the outcry, journalists elevate it onto a mainstream communication platform and support the process of scandalization. Content analysis was used to explore how journalists, working for German-language media, cover this phenomenon. Over a period of 16 months, 130 online firestorms were identified and analyzed. Based on a typology of online firestorms, we have found that the majo…
Sicilian transitional waters: Current status and future development
2010
To appraise the current knowledge of Sicilian transitional waters (TWs), a review was undertaken of the information available on these ecosystems. In detail, a synthesis of the current status is reported, highlighting for each area the ecological features and status, historical data, conservation regime, environmental emergencies and anthropic pressures to which they are subject. The Sicilian TWs reviewed include coastal ponds and lakes, mires and areas with active and nonactive saltworks. Almost all of these ecosystems are affected by several protection regimes because of their high naturalistic value, although current knowledge is limited and fragmented. A few areas have received more att…
Cine distópico y crisis social. El caso de la adaptación cinematográfica de Los Juegos del Hambre
2016
El cine, y en concreto el cine mainstream, constituye un pilar fundamental en las estructuras culturales pero también sociales y económicas a través de las cuales el sistema capitalista se representa a sí mismo. En el contexto de un mundo globalizado, la industria cultural estadounidense parece ocupar un papel central en la conformación de imaginarios colectivos a escala mundial. Imaginarios que, al fin y al cabo, constituyen el sistema axiológico que propone formas de vida concretas. En el marco de lo que Žižek (2009) denominaría “capitalismo cultural”, el cine hollywoodense constituiría un elemento de mediación y conformación del sujeto a través del consumo de un tipo de bienes culturales…
A reconsideration of the link between vertical externality and managerial incentives
2018
Previous research revealed that the strategic role of delegation contracts disappears if two quantity†setting firms outsource input production to a monopolistic supplier. I show that this role is restored if the assumption of a downstream duopoly is relaxed. Thus, delegation contracts allow downstream profit†maximizing owners to commit their firms to a behavior that differs from their preferences. This behavior varies nonmonotonically with the number of firms in the downstream market. Corresponding deviations from profit maximization are larger if the upstream monopolist makes a price precommitment. But little to no deviation occurs if the number of firms is large.
Upstream Product Market Regulations, ICT, R&D and Productivity
2013
Our study aims at assessing the actual importance of the two main channels usually contemplated in the literature through which upstream sector anticompetitive regulations may impact productivity growth: business investments in R&D and in ICT. We thus precisely try to estimate what are the specific impacts of these two channels and their shares in total impact as against alternative channels of investments in other forms of intangible capital such as improvements in skills, management and organization. For this, we specify an extended production function relating productivity explicitly to R&D and ICT capital as well as to upstream regulations, and two factor demand functions relating R&D a…
Product Line Choice in Retail Duopoly
2011
This paper develops a successive duopoly model to identify conditions under which differentiated retailers that compete in quantities, when deciding on the range of brands to offer, will carry overlapping product lines. They will do so when retail margins on each brand are not too asymmetric. Otherwise, the less profitable brand is foreclosed from the market. It is shown that welfare increases if the upstream industry is perfectly competitive, even though fewer brands may be sold. With price competition though, exclusive dealing arises when retailers are not too differentiated and in-store competition is sufficiently intense.
Contingent reward leader behaviour: Where does it come from?
2010
As many academics have pointed out, while researchers have learned a great deal about the effects of contingent reward (CR) leader behaviour, relatively little is known about its genesis. CR transactional leadership is traditionally viewed as an independent variable which exerts influence downstream. However, if we are to understand how to influence, improve or modify these downstream effects, we need to shift our focus upstream towards the study of transactional leadership as a dependent variable. In line with this reasoning, we put forward the hypothesis that a contextual variable (organizational learning capability) and a subordinate's characteristic (employability) are antecedents of CR…
Stratégie du e-commerçant, accessibilité du produit et logistique urbaine
2013
Several factors impact urban logistics, among them, the recent evolution of e-commerce, by the new flows that it introduces in the city. It seemed interesting to us to understand urban logistics in this way, taking an original point of view, that of the upstream part of the logistics chain, namely the e-commerce strategy. We were thus able to highlight strategic and structural choices having consequences on product accessibility and urban logistics.
The effect of cooperative infrastructure fees on high-speed rail and airline competition
2021
Abstract This paper explores the effects of cooperation between rail and air infrastructures in setting per-passenger fees prior to competition among airlines and high-speed rail (HSR) in a transport network. It is shown that, for a sufficiently low degree of substitution, cooperation results in lower fees and greater HSR traffic than under competition. Besides, it leads to more connecting passengers. An empirical application allows for a quantitative assessment of cooperation. Gains to passengers and operators are sizeable when cooperation either involves all infrastructure managers or the rail and the hub airport managers. Welfare gains are in the range of 10.4–11.1%. Our contribution off…
Interbasin Water Transfers in Spain: Interregional Conflicts and Governance Responses
2014
Semiarid and drought-prone Spain has managed to meet ever-increasing water demands for more than 50 years through the construction of publicly funded hydraulic infrastructure. Interbasin water transfers are the most expensive and complex supply-side tool used. They are also the most controversial, often associated with such unintended consequences as deteriorating freshwater ecosystems, disappearing recreational opportunities provided by aquatic ecosystems, and the loss of development opportunities for downstream communities. This situation has become increasingly unstable over the past decade due to the scarcity of new supply augmentation alternatives, political changes involving European …
