The aim of this study is two folded. We wish to investigate if there is a value premium from hedging jet fuel exposure for American and European airlines. We also seek to answer if airlines can affect their probability to default by using Risk Management. During the period 2003 – 2006 there existed a value premium for airlines that hedged their expected future consumption of jet fuel. This premium
Religious Experience Revisited explores a dilemma which has haunted the study of religion since William James. Is religion rooted in experiences? Is religion rooted in expressions? How are experiences and expressions related? The contributors to this international and interdisciplinary compilation explore the possibilities and the impossibilities of a hermeneutics of religion. Combining theology a
The search for certainty in a world that is often so binary – where choosing between two options seems to be the better (and simpler) alternative – gives meaning to the expression «a picture is worth a thousand words». But if we are running away from simplicity, why choose between the two?Since the advent of photography, the scientific community has had a tool with which to provide objective knowl
This chapter reviews the available empirical evidence for a universal metaphoric structure such as TIME IS SPACE and its effects on temporal cognition in L2 users. The chapter covers previous experimental evidence that lends support to the psychological reality of the TIME IS SPACE metaphor, while also revealing cross-linguistic differences in how this fundamental metaphor is instantiated across t
Vehicle-to-vehicle (VTV) wireless communications have many envisioned applications in traffic safety, congestion avoidance, etc., but the development of suitable communications systems and standards requires accurate models for the VTV propagation channel. This paper provides an overview of existing VTV channel measurement campaigns, describing the most important environments, and the delay spread
The low-temperature phase transitions of thermoelectric Zr 4 Sb 3 have been characterized using singlecrystal X-ray diffraction, electrical resistance, and thermal conductivity measurements. Room-temperature stable, disordered β-Zn
Educational software in the form of games or so called “computer assisted intervention” for young children has become increasingly common receiving a growing interest and support. Currently there are, for instance, more than 1,000 iPad apps tagged for preschool. Thus, it has become increasingly important to empirically investigate whether these kinds of software actually provide educational benefi
The development of T-cell leukaemia following the otherwise successful treatment of three patients with X-linked severe combined immune deficiency (X-SCID) in gene-therapy trials using haematopoietic stem cells has led to a re-evaluation of this approach. Using a mouse model for gene therapy of X-SCID, we find that the corrective therapeutic gene IL2RG itself can act as a contributor to the genesi
The transient-state kinetic consequences of the coupling of a single-enzyme reaction to other metabolic reactions have been examined in generalized terms. Analytical data are presented which specify under what conditions such coupling may lead to an oscillatory transient rate behaviour of a reaction system involving an enzyme operating by a Michaelian mechanism. The results indicate that the prese
Recent research has shed light on the various tradeoffs involved in carbon forestry, i.e. the pursuit of international forestry projects to help mitigate climate change. This article contributes to these debates by highlighting the importance of resource quality and degradation in evaluating project benefits and tradeoffs. Focusing on the case of an industrial tree plantation in Uganda, the Kachun
Using scanning electron microscopy guidance, atomically resolved scanning tunneling microscopy investigations inside openings formed during the decomposition of a thick SiO2 film on a Si(111) surface have been performed. We report, for the first time, the presence of Ni atoms inside self-formed openings. The SiO2 decomposition as a function of annealing temperature and time was studied. By compari
The primary cytogenetic abnormality in acute promyelocytic leukemia (APL; FAB M3) is a reciprocal translocation, t(15;17)(q22;q12), which serves to fuse the PML gene on chromosome 15 to the retinoic acid receptor alpha (RARA) gene on chromosome 17. A PML-RARA fusion message transcribed from the der(15) is thought to mediate leukemogenesis. Two APL patients with simple variants of this translocatio
Although the divergence over the last decades between Europe and USA has drawn much attention, the dispersion of rates of economic growth is even larger among the countries within Europe. There is reason to presume that the more successful among the European countries are those that have set more innovations into production. This paper exploits the correlation between innovation, as materialized i
Relational thinking has recently gained increasing prominence across academic disciplines in an attempt to understand complex phenomena in terms of constitutive processes and relations. Interdisciplinary fields of study, such as science and technology studies (STS), the environmental humanities, and the posthumanities, for example, have started to reformulate academic understanding of nature-cultu
Drawing upon earlier studies of reforms and institutional changes in higher education, the purpose of this paper is to trace how the understanding of accountability has changed over the past twenty years and how it is understood to have impacted on higher education institutions. We do so by reviewing more than 350 papers and by asking three questions: Who answers to whom? For what are they answeri
