Of Trees and Birds
(2019)
Gisbert Fanselow’s work has been invaluable and inspiring to many researchers working on syntax, morphology, and information structure, both from a theoretical and from an experimental perspective. This volume comprises a collection of articles dedicated to Gisbert on the occasion of his 60th birthday, covering a range of topics from these areas and beyond. The contributions have in common that in a broad sense they have to do with language structures (and thus trees), and that in a more specific sense they have to do with birds. They thus cover two of Gisbert’s major interests in- and outside of the linguistic world (and perhaps even at the interface).
Background. Endothelin 1 contributes to renal blood flow control and pathogenesis of kidney diseases. The differential effects, however, of endothelin 1 (ET-1) on afferent (AA) and efferent arterioles (EA) remain to be established.
Methods. We investigated endothelin type A and B receptor (ETA-R, ETB-R) functions in the control of AA and EA. Arterioles of ETB-R deficient, rescued mice [ETB (-/-)] and wild types [ETB(+/+)] were microperfused.
Results. ET-1 constricted AA stronger than EA in ETB (-/-) and ETB(+/+) mice. Results in AA: ET-1 induced similar constrictions in ETB(-/-) and ETB(+/+) mice. BQ-123 (ETA-R antagonist) inhibited this response in both groups. ALA-ET-1 and IRL1620 (ETB-R agonists) had no effect on arteriolar diameter. L-NAME did neither affect basal diameters nor ET-1 responses. Results in EA: ET-1 constricted EA stronger in ETB(+/+) compared to ETB(-/-). BQ-123 inhibited the constriction completely only in ETB(-/-). ALA-ET-1 and IRL1620 constricted only arterioles of ETB(+/+) mice. L-NAME decreased basal diameter in ETB(+/+), but not in ETB(-/-) mice and increased the ET-1 response similarly in both groups. The L-NAME actions indicate a contribution of ETB-R in basal nitric oxide (NO) release in EA and suggest dilatory action of ETA-R in EA.
Conclusions. ETA-R mediates vasoconstriction in AA and contributes to vasoconstriction in EA in this mouse model. ETB-R has no effect in AA but mediates basal NO release and constriction in EA. The stronger effect of ET-1 on AA supports observations of decreased glomerular filtration rate to ET-1 and indicates a potential contribution of ET-1 to the pathogenesis of kidney diseases.
Das vorliegende Heft 16 der Reihe Studien zu Grund- und Menschenrechten enthält den Tagungsband zum Workshop „Mechanismen zur Folterverhütung im Vergleich“, welcher am 6. und 7. Oktober 2010 in Potsdam stattfand und die unterschiedlichen Mechanismen zur Folterprävention auf universeller, regionaler und nationaler Ebene beleuchtete.
In the humid tropics, continuing high deforestation rates are seen alongside an increasing expansion of secondary forests. In order to understand and model the consequences of these dynamic land-use changes for regional water cycles, the response of soil hydraulic properties to forest disturbance and recovery has to be quantified.At a site in the Brazilian Amazonia, we annually monitored soil infiltrability and saturated hydraulic conductivity (K-s) at 12.5, 20 cm, and 50 cm soil depth after manual forest conversion to pasture (year zero to four after pasture establishment), and during secondary succession after pasture abandonment (year zero to seven after pasture abandonment). We evaluated the hydrological consequences of the detected changes by comparing the soil hydraulic properties with site-specific rainfall intensities and hydrometric observations. Within one year after grazing started, infiltrability and K-s at 12.5 and 20 cm depth decreased by up to one order of magnitude to levels which are typical for 20-year-old pasture. In the three subsequent monitoring years, infiltrability and K-s remained stable. Land use did not impact on subsoil permeability. Whereas infiltrability values are large enough to allow all rainwater to infiltrate even after the conversion, the sudden decline of near-surface K-s is of hydrological relevance as perched water tables and overland flow occur more often on pastures than in forests at our study site. After pasture abandonment and during secondary succession, seven years of recovery did not suffice to significantly increase infiltrability and K-s at 12.5 depth although a slight recovery is obvious. At 20 cm soil depth, we detected a positive linear increase within the seven-year time frame but annual means did not differ significantly. Although more than a doubling of infiltrability and K-s is still required to achieve pre-disturbance levels, which will presumably take more than a decade, the observed slight increases of K-s might already decrease the probability of perched water table generation and overland flow development well before complete recovery.
Theories of decision-making and its neural substrates have long assumed the existence of two distinct and competing valuation systems, variously described as goal-directed vs. habitual, or, more recently and based on statistical arguments, as model-free vs. model-based reinforcement-learning. Though both have been shown to control choices, the cognitive abilities associated with these systems are under ongoing investigation. Here we examine the link to cognitive abilities, and find that individual differences in processing speed covary with a shift from model-free to model-based choice control in the presence of above-average working memory function. This suggests shared cognitive and neural processes; provides a bridge between literatures on intelligence and valuation; and may guide the development of process models of different valuation components. Furthermore, it provides a rationale for individual differences in the tendency to deploy valuation systems, which may be important for understanding the manifold neuropsychiatric diseases associated with malfunctions of valuation.
In 2009, 'Palestine' lodged a declaration recognizing the jurisdiction of the ICC under Article 12(3). However, in April 2012, the OTP determined that this declaration had not brought about the result, of providing for the ICC's jurisdiction, pending clarification from the political organs of the UN concerning the legal status of Palestine within the organization. On 29 November 2012, the General Assembly granted Palestine the status of a non-member observer state within the UN framework, thereby fulfilling the condition mentioned by the OTP in April 2012. It is against this background that the article considers the current legal effects of the 2009 Palestinian declaration. In particular, it addresses the issue of whether the declaration, when read in conjunction with the 29 November 2012 decision, possesses retroactive effect, i.e. whether it provides, as claimed, for the Court's temporal jurisdiction from 1 July 2002 onwards or rather starting only from 29 November 2012.
... the current status granted to Palestine by the United Nations General Assembly is that of 'observer', not as a 'Non-member State'. ... [T]his... informs the current legal status of Palestine for the interpretation and application of article 12 [Rome Statute]. ... The Office could in the future consider allegations of crimes committed in Palestine, should competent organs of the United Nations... resolve the legal issue relevant to an assessment of article 12. ... International Criminal Court, Office of the Prosecutor, 'Situation in Palestine', 3 April 2012
The adoption, in Kampala in June 2010, of amendments to the Rome Statute on the crime of aggression was hailed as a historic milestone in the development of the international Criminal Court (ICC). However, the manner in which these amendments are supposed to enter into force runs the risk of undermining the rules of the international law of treaties, as well as the legality and acceptability of the Kampala compromise itself The author examines the relevant amendment procedures provided for in the ICC Statute and the compatibility with them of the amendment procedure chosen in Kampala and ultimately warns of the legal consequences which may follow from the Review Conference's somewhat-Alexandrian solution.
