Applications of satellite remote sensing for research and heritage management in Indian prehistory

Multidisciplinary spatial studies are relatively limited in Indian archaeology, despite their potential for research and heritage management. This paper discusses applications of satellite remote sensing, field studies and GIS, in the context of Palaeolithic archaeology. The study region covers an area of around 8000 km², in the state of Tamil Nadu, South India, and is characterized by a rich and diverse Palaeolithic record. Satellite images of varied spatial resolutions were interpreted to address both regional and site-specific research questions. Thematic maps were generated from satellite data and refined with intensive field investigations. These were used for demarcating sources of raw material, and in investigating variability in the distribution of sites through time in relation to a range of geological and geomorphological features. Satellite data and field studies also aided in mapping impacts on sites resulting from modern landuse patterns. The paper also discusses the development and testing of a model to detect potential areas where new sites may be rapidly located.     

Using Teaching Observations and Reflective Practice to Challenge Conventions and Conceptions of Teaching in Geography

Cultural activities such as teaching and learning are highly complex systems that are deeply embedded in a wider culture and these factors impede change. Despite feeling directly the effect of the recent drive towards mass participation in higher education, most lecturers have not accounted for these changes in their teaching methods. Unless lecturers engage in critical reflection and ongoing discovery they stay trapped in unexamined judgements, interpretations, assumptions and expectations. Collaborative teaching observations and reflective practice were conducted by the author and colleagues with a range of experience within a geography department. Several surprising discrepancies appeared between lecturers' expectations and observations of the teaching sessions. The experience showed that, regardless of teaching experience, lectures allow the lecturer in his/her routine practice to neither appreciate his/her performance nor be aware of student understanding. Reflection on these experiences caused the re-evaluation of events and experience and the investigation of other firmly held beliefs that were frustrating and difficult to explain. If lecturers are to become proactive in their professional development, to question their teaching practice and become reflective practitioners, then our teaching culture must embrace the need for change and differences in teaching and learning.     

Electoral salience and the costs of voting at national, sub-national and supra-national elections in the UK: a case study of Brent, UK

This paper considers the impact of distance to polling station upon electoral turnout. Using polling station level data from a London borough, it examines three types of election – parliamentary, European and local elections – over a twenty year period. The UK is notable among western liberal democracies for its relatively large turnout gap – the percentage point difference between turnout at elections for the Westminster parliament compared to that for other institutions, including local councils and the supra-national European parliament. This research considers the hypothesis that in high information, high salience elections for the national parliament the costs of voting associated with travelling to a polling station to vote in person are perceived as either low or insignificant but that in low information, low salience elections, those costs are perceived as higher and may act as a deterrent upon voting. A series of multi-level models consider the relationships between the dependent variable, percentage turnout, and a range of independent variables, including socio-economic characteristics, marginality as well as the spatial context. We show that there is indeed a relationship between distance and voter turnout, and other spatial and contextual variables, which are stronger for the lower salience European and local elections than for the higher salience national elections. Hence we conclude that the local geography of the polling station can have a significant impact on voter turnout and that there should be a more strategic approach to the siting of polling stations.     

Opportunities and constraints for intensive agriculture in the Hawaiian archipelago prior to European contact

Intensive agricultural systems interact strongly and reciprocally with features of the lands they occupy, and with features of the societies that they support. We modeled the distribution of two forms of pre-European contact intensive agriculture – irrigated pondfields and rain-fed dryland systems – across the Hawaiian archipelago using a GIS approach based on climate, hydrology, topography, substrate age, and soil fertility. Model results closely match the archaeological evidence in defined locations. On a broader scale, we calculate that the youngest island, Hawai'i, could have supported 572 km² of intensive agriculture, 97% as rain-fed dryland field systems, while Kaua'i, the oldest island, could have supported 58 km², all as irrigated wetland systems. Irrigated systems have higher, more reliable yields and lower labor requirements than rain-fed dryland systems, so the total potential yield from Kaua'i (49k metric tons) was almost half that of Hawai'i (97k metric tons), although Kaua'i systems required only 0.05 of the agricultural labor (8400 workers, versus 165,000 on Hawai'i) to produce the crops. We conclude that environmental constraints to intensive agriculture across the archipelago created asymmetric production efficiencies, and therefore varying potentials for agricultural surplus. The implications both for the emergence of complex sociopolitical formations and for anthropogenic transformation of Hawaiian ecosystems are substantial.     

Variation in Venues of Slavery and Freedom: Interpreting the Late Eighteenth-Century Cultural Landscape of St. John, Danish West Indies Using an Archaeological GIS

An archaeological GIS is used to examine the late eighteenth-century cultural landscape of St. John, US Virgin Islands. Land use patterns are reconstructed using a combination of historic maps, tax records, and survey reconnaissance. The study demonstrates significant, heretofore undocumented, transitions taking place that reflect dynamic cultural and economic change within Danish West Indian plantation society that includes a significant trend towards land ownership by free-colored St. Johnians more than a half a century before emancipation. These venues of freedom are discussed in relation to broader patterns of estate consolidation and economic shifts.     

A locally-adaptive model of archaeological potential (LAMAP)

A new method for modelling archaeological resource potential is presented that avoids some of the mathematical violations and inconsistencies of previously-favoured techniques. The Minanha research area in west-central Belize and a database of other Maya centres from within Belize are used as a case study for demonstrating the utility of the proposed modelling technique.     

让学生在阅读中感受文本的美

《语文课程标准》在关于阅读教学的建议中指出”：阅读是搜集处理信息、认识世界、发展思维、获得审美体验的重要途径。”文质兼美的语文教材为我们展现了一个璀璨夺目的美的世界。我们应积极引导学生通过文本阅读感受语文之美。语文教学是真善美的统一,是以求真为基础向善的迈进;而美则是向着善的目标迈进的最佳途径。因此我认为,语文课堂教学既是一门科学,又是一门艺术。而阅读是学生应该掌握的一项基本技能。让学生在阅读中提升写作技能、开拓视界、放飞心灵,进而在享受中去阅读,这是做为一个语文教师应该做到的。合理运用阅读能够逐步培养学生探究性学习和创造性学习的能力,教师要引导学生在读中体会情感,在读中获取信患,在读中得到精神的享受。
