QED on a momentum lattice

We investigate the possibility of doing momentum space lattice simulations as an alternative to the conventional method. The procedure is introduced and tested for quenched QED2 and quenched QED3. Interesting physical applications to unquenched QED3 and quenched QED4 are also briefly discussed.Comment: 3 pages, To appear in the proceedings of the LATTICE'93 conference, ILL-(TH)-93-2

An Evaluation of Native-speaker Judgements of Foreign-accented British and American English

This study is the first ever to employ a large-scale Internet survey to investigate priorities in English pronunciation training. Well over 500 native speakers from throughout the English-speaking world, including North America, the British Isles, Australia and New Zealand, were asked to detect and evaluate Dutch pronunciation errors in sentences read by bilingual actors. Through the application of up-to-date statistical procedures, these assessments were analysed and then used to construct hierarchies of error for pronunciation training in the most commonly taught varieties of British and American English. The attitudes of the various groups of native speakers towards error detection and evaluation were found to be strikingly different. Nevertheless, the findings indicate that almost all natives attach considerable significance to pronunciation errors that impede intelligibility. In those cases where there is no loss of intelligibility, they often respond negatively to features that are socially marked in native varieties of English. This effect of stigmatisation was found to differ considerably, for example, between countries such as the United States and Britain. Even non-native pronunciation errors that are very similar to features actually attested in respondents' own accents are not necessarily judged more leniently. In addition to discussing the effects of linguistic background on the judgements of native speakers, this study also considers the error assessments of Dutch teachers and students of English, and provides a brief overview of pronunciation training in the Netherlands. This research will be of interest not only to phoneticians and sociolinguists with an interest in second language acquisition, but also to teachers and students of English pronunciation and accent varieties

Nederland en zijn veteranen 1945-2015: een onderzoek naar de rol van de overheid bij de ontwikkeling van het veteranenbeleid en de uitvoering van de veteranenzorg

Government has a special responsibility for its military. This research is about the care of veterans by government, parliament and society in the period 1945-2015. Therein the central matter is the development of the Dutch veteran policy (1945-2015) and in which way did the government met its responsibilities? To answer the main question, the theory of civil-military relations was used as a theoretical framework. This civil-military relationship concernsthe relationship between society and armed forces as well as the relationship between government and armed forces. Which roles did parliament and society fulfil in the care for veterans? Using six military missions, we researched in what ways the government met their duty of care towards (ex-)military personnel in practice before, during and after a mission.Until 1990 the government had no definition for a ‘veteran’. The military personnel who were deployed in the Dutch East Indies, Korea and the Lebanon as well as smaller missions, did not have veteran status before 1990.When viewing the period 1945-2015, we can conclude that the government did not meet fully its special responsibility to its veterans.Institutions, Decisions and Collective Behaviou

Harnessing Elastic Energy to Transfer Reciprocating Actuation into Rotary Motion

The ability to convert reciprocating, i.e., alternating, actuation into rotary motion using linkages is hindered fundamentally by their poor torque transmission capability around kinematic singularity configurations. Here, we harness the elastic potential energy of a linear spring attached to the coupler link of four-bar mechanisms to manipulate force transmission around the kinematic singularities. We developed a theoretical model to explore the parameter space for proper force transmission in slider-crank and rocker-crank four-bar kinematics. Finally, we verified the proposed model and methodology by building and testing a macro-scale prototype of a slider-crank mechanism. We expect this approach to enable the development of small-scale rotary engines and robotic devices with closed kinematic chains dealing with serial kinematic singularities, such as linkages and parallel manipulators.Comment: 8 pages, 5 figures, journal article submitted to Mechanisms and Machine Theor
