Non-discursive knowledge and the construction of identity. Potters, potting and performance at the bronze age tell of Százhalombatta, Hungary
No full textThis article explores the relationship between the making of things and the making of people at the Bronze Age tell at Százhalombatta, Hungary. Focusing on potters and potting, we explore how the performance of non-discursive knowledge was critical to the construction of social categories. Potters literally came into being as potters through repeated bodily enactment of potting skills. Potters also gained their identity in the social sphere through the connection between their potting performance and their audience. We trace degrees of skill in the ceramic record to reveal the material articulation of non-discursive knowledge and consider the ramifications of the differential acquisition of non-discursive knowledge for the expression of different kinds of potter's identities. The creation of potters as a social category was essential to the ongoing creation of specific forms of material culture. We examine the implications of altered potters' performances and the role of non-discursive knowledge in the construction of social models of the Bronze Ag

Structural analysis and parametric study ballasted track in sandy regions
No full textThe sand intrusion in railway tracks in sandy regions can significantly change the mechanical behaviour of tracks and thus threaten the safety of train operation. This paper presents substantial field tests on both sandy and clean railway tracks to study the effect of sand intrusion on the longitudinal resistance of ballast bed and the vibration behaviour of track structures. After that, a 3D multi-scale the discrete element model is developed to study the micro-contact between ballast particles and the vibration behaviour of sandy tracks during train passing in detail. Also, the effect of train speeds and axle loads on the mechanical behaviour of sandy tracks is discussed. The results show that the sand intrusion increases the vibration acceleration amplitude of rail and sleeper by 11.3% and 50.3%, while ballast bed decreases by 44.9%. Besides, the sand intrusion significantly changes the energy distribution in the track, wherein the frequencies of the highest energy of rail and sleeper are increased while that of the ballast bed is decreased. The parametric study shows the high train speed can cause the increase in overall acceleration of the ballast bed and high axle load can cause an increase in the micro-contact forces between ballast particles, diffusion angle of the contact force chain, displacements of ballast particles, acceleration of ballast particles, and sleeper displacements.Green Open Access added to TU Delft Institutional Repository 'You share, we take care!' - Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.Mechanics and Physics of Structure
Crushed rock and clay amelioration of a nutrient decifient, sandy soil of Maputaland
No full textBibliography: leaves 57-62.Various studies have suggested the possibility that food derived through subsistence agriculture in the Mseleni region of Maputaland contributes to malnutrition within the local community, particularfy within the high proportion of the population which suffers from a severe, disabling form of osteoarthritis. This study was conducted to determine if the application of local crushed rock or black clay to these nutrient deficient, sandy soils would increase available nutrient concentrations and improve the growth of plants in the ameliorated soil
Sandy coastlines under threat of erosion
No full textSandy beaches occupy more than one-third of the global coastline1 and have high socioeconomic value related to recreation, tourism and ecosystem services2. Beaches are the interface between land and ocean, providing coastal protection from marine storms and cyclones3. However the presence of sandy beaches cannot be taken for granted, as they are under constant change, driven by meteorological4,5, geological6 and anthropogenic factors1,7. A substantial proportion of the world’s sandy coastline is already eroding1,7, a situation that could be exacerbated by climate change8,9. Here, we show that ambient trends in shoreline dynamics, combined with coastal recession driven by sea level rise, could result in the near extinction of almost half of the world’s sandy beaches by the end of the century. Moderate GHG emission mitigation could prevent 40% of shoreline retreat. Projected shoreline dynamics are dominated by sea level rise for the majority of sandy beaches, but in certain regions the erosive trend is counteracted by accretive ambient shoreline changes; for example, in the Amazon, East and Southeast Asia and the north tropical Pacific. A substantial proportion of the threatened sandy shorelines are in densely populated areas, underlining the need for the design and implementation of effective adaptive measures.Accepted Author ManuscriptCoastal Engineerin
A reflection on interactional feedback by students of Sanata Dharma University
No full textInteractional feedback as a means of helping second language (L2) learners to
focus on form has received increased attention recently in the field of second
language acquisition (SLA). Moreover, feedback is also considered as an
effective way to help the students improve their ability in learning L2.
Subsequently, as teachers encourage use of the target language in their
classrooms, they must consider how to provide feedback to their students
concerning the accuracy of their utterances. This paper attempts to reveal the
answers for the research question which is “what does interactional feedback
mean to the students?” There are two participants who were willing to share
their lived experiences. The data are in a form of texts and gathered from an indepth
interview in which the data are then extracted to be the themes for the
discussion. For the themes, there are two major themes appear in the study
namely motivation and self-improvement. Motivation was the first theme that
appeared from the study. The comments and feedback could motivate the
participants to perform better in their next speaking practices. Additionally,
motivation indeed becomes one of the positive effects which could make the
participants feel motivated in improving their speaking ability through the
feedback from their lecturers. Self-improvement became the second major
theme from the study. Self-improvement was derived from the participants’
consciousness when they encountered the mistakes that they often committed
when speaking. Contextually, the interactional feedback that the participants
gained from the lecturer made the participants aware of the mistake that they
had committed. Therefore, after gaining the feedbacks from their teacher, they
are triggered to improve their performance in the next speaking assignments

Lloyd (Sandy) H. Ellis Jr. Interview, 2011
No full textThis is an interview with author Lloyd (Sandy) H. Ellis Jr. about his book Sacred Landmarks and his forthcoming book which extends the first work beyond the city limits. In the first part of the interview there is discussion about the first book and how his new book will extend beyond the city limits to look at other sacred landmarks around the city. The next part of the interview Ellis notes the problems with getting access to some institutions and differences between religious groups and the clergy. Throughout the interview unique aspects of these landmarks are noted as well as religious differences. The later part of the interview Ellis notes how the churches have evolved and how parishioners have given insight to these landmarks. At the end of the interview discussion concludes with how the builders deserve credit along with the designers in construction of these landmarks. Ellis also points out how many founding pastors provided the initiative, fund raising, and drive for the construction of these institutions
