On the interpretation of scalar antonyms and their negated equivalents

Antonymy and negation are phenomena that can be studied from many perspectives. In the literature, antonymy is recognized as the most robust of the lexico-semantic relations, important to both the mental organization of the vocabulary and the organization of coherent discourse (Cruse 1986, Fellbaum 1998, Murphy 2003, Willners 2001 and Jones 2002). "Depending on whom you ask, negation may be a logi

The development of agrarian capitalism revisited: Measuring the role of tenant labour on settler farms in Southern Rhodesia, 1900-1960

In this paper we have used primary and secondary sources to make, to our knowledge, the first attempt ever to quantify the role non-wage labour on settler farms in colonial Africa. We have used Southern Rhodesia as a case in point and focused primarily on the role of tenant labour. Our findings show that the rise of wage labour did not mark the end of the latter. On the contrary, the two forms of

Virtual Mobilisation? Linking On-line and Off-line Political Participation among Swedish Facebook Users: Courtesy and Irritation

This paper is a pilot study where Swedish Facebook users are interviewed in virtual focus groups - one consisting of politically active participants and one consisting of not politically active participants - using Facebook itself as the platform. The interviews concerned the attitudes of the participants towards political campaigns and recruitment within Facebook. The preliminary results show tha

Reduction of co-channel interference in GSM by joint channel and data estimation

Multiuser detection is a powerful tool for combating cochannel interference in multiple-access communication systems. In this paper, we investigate the feasibility of achieving increased spectral efficiency in GSM-like TDMA networks by applying multiuser detection. Two special cases are considered: In the first scenario, two users are served simultaneously in the same cell. In the second one, two

Channel estimation and signal detection for UWB:

In this paper, we investigate channel estimation and signal detection for UWB communications. We first investigate channel estimation for UWB systems and then develop a minimum mean-square-error (MMSE) Rake receiver with joint timing and MMSE equalization. The key property of the estimator is that it uses sampling at UWB symbol rate (200Msamples/s), while estimating all relevant channel parameters
