Crystal Nucleation of Colloidal Suspensions under Shear

We use Brownian Dynamics simulations in combination with the umbrella sampling technique to study the effect of shear flow on homogeneous crystal nucleation. We find that a homogeneous shear rate leads to a significant suppression of the crystal nucleation rate and to an increase of the size of the critical nucleus. A simple, phenomenological extension of classical nucleation theory accounts for these observations. The orientation of the crystal nucleus is tilted with respect to the shear direction.Comment: 4 pages, 3 figures, Submitted to Phys. Rev. Let

Microsaccade-rate indicates absorption by music listening

The power of music is a literary topos, which can be attributed to intense and personally significant experiences, one of them being the state of absorption. Such phenomenal states are difficult to grasp objectively. We investigated the state of musical absorption by using eye tracking. We utilized a load related definition of state absorption: multimodal resources are committed to create a unified representation of music. Resource allocation was measured indirectly by microsaccade rate, known to indicate cognitive processing load. We showed in Exp. 1 that microsaccade rate also indicates state absorption. Hence, there is cross-modal coupling between an auditory aesthetic experience and fixational eye movements. When removing the fixational stimulus in Exp. 2, saccades are no longer generated upon visual input and the cross-modal coupling disappeared. Results are interpreted in favor of the load hypothesis of microsaccade rate and against the assumption of general slowing by state absorption

Determining the Future for Louisiana Sugar Cane Products, Inc.: A Case Study Analyzing Vertical Coordination Options

Deciding how to coordinate activities can be a challenge posed in any marketing chain. This case involves an agricultural cooperative that has focused entirely on marketing raw sugar cane for additional refinement. Recent dramatic shifts in the sector have caused the members of the cooperative to consider building a facility that will process the raw sugar cane. In so doing, the cooperative can consider using the spot market, using contracts, vertically coordinating, or vertically integrating. This case study of Louisiana Sugar Cane Products, Inc. is a unique, real-life case that can be widely used in marketing and cooperatives courses.Agribusiness, Crop Production/Industries,

Chapter 2: A New Crisis Mechanism for the Euro Area

The European debt crisis followed the US financial crisis with a delay of one and a half years. While its first signs were visible in November and December of 2009 when the rating agency Fitch downgraded Ireland and Greece, it culminated on 28 April 2010 when the intra-day interest rate for two-year Greek government bonds peaked at 38 percent. Since then capital markets have been extremely unstable, showing signs of distrust in the creditworthiness of the GIPS countries: Greece, Ireland, Portugal and Spain. The European Union reacted by preparing voluminous rescue plans that, at this writing (January 2011), have been resorted to by Greece and Ireland.

Chapter 3: The effect of globalisation on Western European jobs: curse or blessing?

This chapter analyses the impact of increased economic integration with low-wage economies on Western European jobs: the message is that when taking all effects into account, globalisation is more likely in the end to raise rather than to reduce employment, because it will help making labour markets more flexible. The challenge for policy is to counter adverse income distribution effects, but to do so in a way that employment is not harmed.

Chapter 4: Spain

Spain has suffered a lot from the current crisis and is the first large economy that may find itself in need of fiscal rescue. If this happens it may prove quite damaging to the euro. Yet, since the mid-1990s, Spain was a champion of growth and fiscal stability; its unemployment had fallen rapidly to the levels that prevailed in the rest of the European Union. This chapter discusses the reasons why such a virtuous initial situation deteriorated so sharply since the start of the crisis. Was this just bad luck or were the booming years just a mirage?
