Structural Change in the Dairy Sectors of Germany and The Netherlands - A Markov Chain Analysis

With the milk quota announced to be abolished in the future, the dairy sector is going to face a significant policy regime shift. This paper sets out to analyze the impact of milk quotas on the dairy farm structure of two important milk producing member states: Germany and the Netherlands. Based on proper behavioral assumptions, non stationary Markov chain models are specified and estimated using a generalized cross entropy procedure, which takes into account both sample and prior information. Moreover four mobility indicators characterizing structural change are developed and calculated. Structural change in the dairy sector as measured by the mobility measures is faster in West Germany than in the Netherlands. However, in the transition region East Germany structural change outpaces that of the traditional German and Dutch dairy sectors by a factor two or more. The introduction of milk quotas as of April 1, 1984 reduced overall farm mobility for the Netherlands, but increased mobility in West Germany. However, in both cases the milk quotas lead to an increase in upward mobility.Markov Chain, Milk Quota, Structural Change, Livestock Production/Industries,

Competing itinerant and localized states in strongly correlated BaVS3_3

The electronic structure of the quasi-lowdimensional vanadium sulfide \bavs3 is investigated for the different phases above the magnetic ordering temperature. By means of density functional theory and its combination with dynamical-mean field theory, we follow the evolution of the relevant low-energy electronic states on cooling. Hence we go in the metallic regime from the room temperature hexagonal phase to the orthorhombic phase after the first structural transition, and close with the monoclinic insulating phase below the metal-insulator transition. Due to the low symmetry and expected intersite correlations, the latter phase is treated within cellular dynamical mean-field theory. It is generally discussed how the intriguing interplay between band-structure and strong-correlation effects leads to the stabilization of the various electronic phases with decreasing temperature.Comment: 12 pages, submitted to PR

Selective targeting of proteins by hybrid polyoxometalates: Interaction between a bis-biotinylated hybrid conjugate and avidin

The Keggin-type polyoxometalate [\u3b3-SiW10O36]8 12 was covalently modified to obtain a bis-biotinylated conjugate able to bind avidin. Spectroscopic studies such as UV-vis, fluorimetry, circular dichroism, coupled to surface plasmon resonance technique were used to highlight the unique interplay of supramolecular interactions between the homotetrameric protein and the bis-functionalized polyanion. In particular, the dual recognition mechanism of the avidin encompasses (i) a complementary electrostatic association between the anionic surface of the polyoxotungstate and each positively charged avidin subunit and (ii) specific host-guest interactions between each biotinylated arm and a corresponding pocket on the tetramer subunits. The assembly exhibits peroxidase-like reactivity and it was used in aqueous solution for L-methionine methyl ester oxidation by H2O2. The recognition phenomenon was then exploited for the preparation of layer-by-layer films, whose structural evolution was monitored in situ by ATR-FTIR spectroscopy. Finally, cell tracking studies were performed by exploiting the specific interactions with a labeled streptavidin

Ultracold Chemistry and its Reaction Kinetics

We study the reaction kinetics of chemical processes occurring in the ultracold regime and systematically investigate their dynamics. Quantum entanglement is found to play a key role in driving an ultracold reaction towards a dynamical equilibrium. In case of multiple concurrent reactions Hamiltonian chaos dominates the phase space dynamics in the mean field approximation.Comment: 15 pages, 5 figure

Testosterone affects song modulation during simulated territorial intrusions in male black redstarts (Phoenicurus ochruros)

Although it has been suggested that testosterone plays an important role in resource allocation for competitive behavior, details of the interplay between testosterone, territorial aggression and signal plasticity are largely unknown. Therefore, we investigated if testosterone acts specifically on signals that communicate the motivation or ability of individuals to engage in competitive situations in a natural context. We studied the black redstart, a territorial songbird species, during two different life-cycle stages, the early breeding phase in spring and the non-breeding phase in fall. Male territory holders were implanted with the androgen receptor blocker flutamide (Flut) and the aromatase inhibitor letrozole (Let) to inhibit the action of testosterone and its estrogenic metabolites. Controls received a placebo treatment. Three days after implantation birds were challenged with a simulated territorial intrusion (STI). Song was recorded before, during and after the challenge. In spring, both treatment groups increased the number of elements sung in parts of their song in response to the STI. However, Flut/Let-implanted males reacted to the STI with a decreased maximum acoustic frequency of one song part, while placebo-implanted males did not. Instead, placebo-implanted males sang the atonal part of their song with a broader frequency range. Furthermore, placebo-, but not Flut/Let-implanted males, sang shorter songs with shorter pauses between parts in the STIs. During simulated intrusions in fall, when testosterone levels are naturally low in this species, males of both treatment groups sang similar to Flut/Let-implanted males during breeding. The results suggest that song sung during a territorial encounter is of higher competitive value than song sung in an undisturbed situation and may, therefore, convey information about the motivation or quality of the territory holder. We conclude that testosterone facilitates context-dependent changes in song structures that may be honest signals of male quality in black redstarts

Understanding suicide terrorism: Insights from psychology, lessons from history

History and psychology give us some powerful tools for understanding suicide terrorism. History quickly teaches that this tactic is not the reserve of any one religion and there are many examples from the past of individuals with very different motivations who are willing to sacrifice their life in an effort to kill others. Thus it is a mistake to see modern suicide terrorism as inherently an ‘Islamic problem’. Similarly, history also teaches us that perspective is important. The more you sympathise with the perpetrators’ cause, then the more you tend to explain the perpetrators’ decisions and motivations in very different (and usually much more positive) ways. If we disagree with the aims, then explanations begin to cluster around issues such as brainwashing, indoctrination, grooming, and radicalisation of vulnerable personalities. The truth almost certainly lies somewhere in between. The lesson from psychology is that there is no obvious suicide terrorist personality. Individuals reach the point of carrying out a suicide attack through a process which generally has more to do with social psychology then with the tenets of clinical or abnormal psychology. Used effectively, these insights can be tremendously helpful in stripping away many of the myths and assumptions which surround debates on suicide terrorism and leave us with a more realistic assessment of the perpetrators, who they are, how they see themselves and what forces motivate and drive them. A realistic understanding here is a vital first step in developing more effective approaches for both countering and preventing suicide terrorism

Risk assessment of terrorist and extremist prisoners

Our understanding of the risk assessment of terrorist and extremist prisoners is in its infancy, yet this is clearly a critical issue. How can one tell if a prisoner is still dangerous or not? What are valid measures to assess risk and what type of evidence is worth examining? In considering risk assessment of terrorists and extremists in prison settings there are a range of essential issues to consider. Crucially, not all terrorist and extremist prisoners are the same and factors which apply clearly to one individual will not apply equally strongly to others. As a result, effective risk assessment processes need to be nuanced. This chapter highlights the range of issues which are likely to be of most use when considering risk assessment in the context of a terrorist prisoner, and also identifies what sources of information can provide the necessary insight to inform this assessment

Ferocious Times: The IRA, the RIC, and Britain’s failure in 1919-1921.

The 1916 Rising was, in military terms, a shambolic failure. Despite the fact that Britain was locked in a gruelling struggle with Germany, the Rising was still utterly crushed within a week. How then, in the aftermath of victory against Germany, did Britain fail to win the subsequent struggle with the IRA between 1919 and 1921? This article assesses some of the key factors which played out in the conflict, drawing particular attention to the IRA’s focus on the RIC and the consequences of this and then, later, how distorted perceptions of the proximity of success ultimately undermined British commitment. One of the most remarkable features of the conflict was the widespread belief among many on the British side (and more than a few in the Republican camp) that the IRA was on the verge of total defeat when the truce was agreed in 1921. The IRA had suffered heavy casualties and were running low on weapons and ammunition. Yet, somehow the movement prevailed. This article aims to shed light on how and why that happened
