Cooperative and corporate farms have retained an important role for agricultural production in many transition countries of Central and Eastern Europe. Despite this importance, these farms' ownership structure, and particularly the ownership's effect on their investment activity, which is vital for efficient restructuring and the sector's future development, are still not well understood. This paper explores the ownership-investment relationship using data on Czech farms from 1997 to 2008. We allow for ownership-specific variability in farm investment behaviour analyzed by utilizing an error-correction accelerator model. Empirical results suggest significant differences in the level of investment activity, responsiveness to market signals, investment lumpiness, as well as investment sensitivity to financial variables among farms with different ownership characteristics. These differences imply that the internal structure of the Czech cooperative and corporate farms will be developing in the direction of a decreasing number of owners and an increasing ownership concentration.

The principle of gender equality forms a part of the EU’s social policy and serves equally men and women. So far, fourteen directives concerning gender equality have been adopted in the EU, with the New Equal Treatment Directive as the latest one. The EU has developed different models to promote gender equality: equal treatment, positive action and most recently gender mainstreaming. The equal treatment model is primarily concerned with formal equality and it unfortunately prevails in the ECJ’s rulings. Indeed, this paper argues that so far, the ECJ has not managed to develop a firm and consistent case law on gender equality, nor to stretch it coherently to positive action and gender mainstreaming. It seems that in spite of some progress in promoting the position of women, the ECJ’s case law has recently taken a step backwards with its conservative judgments in e.g. the Cadman case. Overall, this paper aims at summing up and evaluating the most important cases of the ECJ on gender equality.

Fiscal consolidation is essential to ensure the sustainability of eurozone countries’ public debt. However, as a principle, consolidation should not be pursued at a pace unnecessarily undermining growth in the short term. Repeated downward revisions of growth call for the use of the flexibility foreseen in the EU fiscal framework. The Commission should adapt the deadlines for fiscal correction to prevent excessive, pro-cyclical adjustment in 2013. In turn, adequate surveillance and coordination must ensure structural adjustments constitute the core of fiscal consolidation plans.

The EU democratization policies have not achieved the expected results in Eastern Partnership (EaP) countries. On the contrary, they have led to the outbreak of the most important crisis in Europe after the end of the cold war. A new vision of cooperation in the field of democracy is necessary in the East, as long as even Georgia and Moldova, countries considered to be the most advanced among the EaP states, have not registered essential progress in the democratization of their societies. Assuming that democratization, as part of EU’s neighbourhood policies, can be considered a threat to Russia and hence a ‘destabilizing factor’ for the EU partners, this thesis tried to understand what changes can be made to EU policies and to what extent cooperation between EU and Russia is possible in the process developing democratization policies in Georgia and Moldova. While arguing for the revitalization of the instruments used for the implementation of the democratization policies, this thesis finds that cooperation between the EU and Russia in the field of democracy is excluded as long as the two geo-political actors have different values and different views on the notion of democracy. The most likely cooperation that might occur between EU and Russia is the establishment of a Common Economic Space ‘from Lisbon to Vladivostok’. Even though such a scenario would have the potential to reduce confrontation between the two actors in the common neighbourhood, this cooperation would, however, have a negative impact on the on-going democratic reforms in Georgia and Moldova.

Through the widespread use of postmortem computed tomography, inner livores of the lungs have become a frequently observed phenomenon in the field of forensic medicine. Yet their time-dependent development, notably in comparison with the widely studied external livores, remains poorly understood. We present a unique homicide case where the victim was discovered in supine position with correspondent external livores fixed exclusively on the rear side. Yet upon postmortem computed tomography, the victim presented pronounced inner livores within the depending dorsal areas of both lungs but also vertical sedimentation levels solely within the right lung, suggesting an initial right-hand side position and a postmortem re-positioning of the body. Interestingly, this was consistent with tangible hints of postmortem manipulation on-site. It is likely that this repositioning occurred sometime during the early postmortem interval (<6 h) as the external livores have completely rearranged to the final supine position. The presented case suggests different development patterns of inner and outer livores, highlighting the necessity for controlled studies that explore the formation and fixation processes of livor mortis in internal organs. A better understanding of these issues can prove useful in forensic examinations.
