A number of researchers have offered hypotheses about the syntactic relationship between Tense and Negation. Zanuttini 1996, for example, has argued that the head NEG may only occur in the presence of Tense. This paper examines data on negation in 15 languages which has been collected in an ongoing typological research project, PARATYP. The study focuses on the difference between prohibitive and n

This is a study of farm dynamics in eight African countries, drawing on a sample of more than 3000 farm households. It deals mainly with food crops and in detail with maize and makes a longitudinal analysis by systematically comparing current conditions with those obtaining when the farm was set up under its present management. From the study emerges an overall picture of inadequately exploited pr

On 10 September 1751 the Swedish botanist Pehr Osbeck visited the outskirts of Canton. On his way back into the city he was surrounded by a gang of robbers who demanded money from him. When they did not receive any money, they pelted Osbeck with large stones; it was very fortunate that he was not severely injured. One of the questions this paper discusses is what were the laws in China at that tim

Scientific research communities have benefited recently from the increasing availability of computing and data infrastructures with unprecedented capabilities for large scale distributed initiatives. These infrastructures are largely defined and enabled by the middleware they deploy. One of the major issues in the current usage of research infrastructures is the need to use similar but often incom

We report on theoretical results of magnetic field induced transitions (MITs) in Ne- and Be-like ions without nuclear spin for two applicalions. Firstly, MITs are promising candidates in the determination of magnetic fields in plasmas. In our work on Ne-like ions we present accurate theoretical MIT rates for 2p(6 1)S(O) - 2p(5)3s 3P(O),2 [11. Purthermore, for Be-like ions, it has been proposed to

Human fibrocytes are bone marrow-derived mesenchymal progenitor cells that express a variety of markers related to leukocytes, hematopoietic stem cells and a diverse set of fibroblast phenotypes. Fibrocytes can be recruited from the circulation to the tissue where they further can differentiate and proliferate into various mesenchymal cell types depending on the tissue niche. This local tissue nic

Though there is a very large literature examining whether energy use Granger causes economic output or vice versa, it is fairly inconclusive. Almost all existing studies use relatively short time series, or panels with a relatively small time dimension. We apply Granger causality and cointegration techniques to a Swedish time series dataset spanning 150 years to test whether increases in energy us

The evolution of multicellular organisms represents one of approximately eight major evolutionary transitions that have occurred on earth [1-4]. The major challenge raised by this transition is to explain why single cells should join together and become mutually dependent, in a way that leads to a more complex multicellular life form that can only replicate as a whole. It has been argued that a hi

Tax incentives can be a policy instrument to fund the arts and culture. Such incentives must meet certain rules and principles, including, for EU Member States, EU requirements. In addition, various other aspects must be taken into account in the appreciation of tax incentives as a cultural funding instrument. This includes, on the one hand, notions of fairness, concerns about ‘philanthrocapitalis

Epilepsy affects approximately 50 million people worldwide, and over 30% of patients are considered treatment resistant to currently available anti-seizure drugs. Neuropeptide Y (NPY) has been shown to inhibit excitatory synaptic transmission in hippocampal slices from human epilepsy patients via Y2 receptors (Y2Rs), and overexpression of NPY and/or Y2R in the hippocampus reduces seizures in roden
