On numerical relativistic hydrodynamics and barotropic equations of state

2012

The characteristic formulation of the relativistic hydrodynamic equations (Donat et al 1998 J. Comput. Phys. 146 58), which has been implemented in many relativistic hydro-codes that make use of Godunov-type methods, has to be slightly modified in the case of evolving barotropic flows. For a barotropic equation of state, a removable singularity appears in one of the eigenvectors. The singularity can be avoided by means of a simple renormalization which makes the system of eigenvectors well defined and complete. An alternative strategy for the particular case of barotropic flows is discussed.

The droplets exchanging in the trap causes visible scattering of the laser beam focused on the droplet. The obvious change of laser light intensity can be used for detection of droplet exchange.

Pleasurable music affects reinforcement learning according to the listener.

2013

Mounting evidence links the enjoyment of music to brain areas implicated in emotion and the dopaminergic reward system. In particular, dopamine release in the ventral striatum seems to play a major role in the rewarding aspect of music listening. Striatal dopamine also influences reinforcement learning, such that subjects with greater dopamine efficacy learn better to approach rewards while those with lesser dopamine efficacy learn better to avoid punishments. In this study, we explored the practical implications of musical pleasure through its ability to facilitate reinforcement learning via non-pharmacological dopamine elicitation. Subjects from a wide variety of musical backgrounds chose…

Challenging the negative images of Haiti at a pre-visit stage using visual online learning materials

2016

Post-conflict destinations can struggle to attract visitors because of their negative image. Research addressing this remains limited. The same can be said about the education of tourists. This research paper contributes to the literature in both areas as it examines the proposition that the education of tourists at a pre-visit stage using online, game-based material could be effective in challenging the negative perception of these destinations. From a destination management point of view, this paper offers an alternative to existing promotional material as there is little evidence at the moment that existing strategies are effective. From a conceptual point of view, this paper contributes…

A Political Scientist's Experience in the Real World of Politics

2009

Doctoral candidates in political science have a universe of potential career options to choose from. These include not only academia, but also the non-governmental sector, political consulting, and government work. When I obtained my doctoral degree in 1993, little did I imagine that within fifteen years I would have tried my hand in all of these fields, including serving as a cabinet minister. In this article, I reflect on how this professional whirlwind came about, how each field helped and/or hindered the others, what these wanderings taught me about post-communist democratic politics, and particularly what lessons a political scientist learned from entering, albeit briefly, the ‘real wo…

Attempts at diversification: Mexico and Pacific Asia

2002

This article aims to explain the development of Mexico's relations with Pacific Asia. Based on the historical background of Mexico's relations with Asia and on internal and international transformations, we identify the interests of Mexican political actors in Pacific Asia. We provide an overview of the existing political and economic relations between Mexico and Pacific Asia, demonstrating that the success of diversification has been very limited. By trying to explain the gap between the strategic goals and the existing relations we focus on the domestic politics in Mexico. We conclude that intra-elite conflicts had a negative effect on the diversification attempts, since those conflicts p…

Trends in EU Energy Policy 1995–2007

2011

Today, climate change and a significant increase in energy consumption are considered to be the two greatest global challenges facing the energy world (e.g., Hasselmann et al. 2003: 1923; IPCC 2007; Kara 2007: 5; Karl and Trenberth 2003: 1719). In addition to the scientific community having a common understanding about these two issues relating to each other, the political decision makers also need to acknowledge it and start building a framework around it – with the same longterm targets. On the EU-level, climate change concerns were already manifested in the White Paper on Energy Policy for the European Union in 1995. The development of the EU’s common energy policy is also the result of …

Impact of Industrial SMEs in the Environment Conservation : A Systematic Mapping Study

2020

Small and medium-sized companies have an impact on the environment where they operate. In some cases, the effects on the environment can be significant within local communities leading to a series of negative processes, such as emission pollution into the atmosphere, the discharges to rivers and seas, the production of waste; in some cases, it makes the contamination to the soil. This paper presents the results of the systematic mapping study aimed at assessing environmental management in industrial SMEs. Descriptive studies of SMEs emphasize their poor environmental commitment, describing them as primarily interested in controlling pollutant emissions just to comply with regulations. Ninet…
