The Maya “Protoclassic” from the Perspective of Recent Research at Nakum,Peten, Guatemala

Recently, the Maya site of Nakum has been the subject of intensive research by the Institute of Archaeology of the Jagiellonian University, Kraków, Poland. This work has significantly enriched our knowledge of the ancient Maya of northeastern Guatemala, especially during the so-called Terminal Preclassic or Protoclassic period (ca. 100 b.c.–a.d. 300), when many Maya centers suffered decline. The Protoclassic covers the transitional moment between two important periods of Maya chronology, the Preclassic and Classic, but so far, the typical ceramic components of this phase have been found in only a handful of Maya sites. Our research indicates that Nakum underwent important building programs and stable cultural growth during the discussed period. Here we discuss evidence of architectural and cultural activity at Nakum during the Terminal Preclassic within a wider geographic context. Our research highlights the role that Nakum played within Maya geopolitics in northeastern Guatemala and also contributes to the understanding of socio-cultural processes that the Maya civilization was undergoing during the as-yet poorly understood Protoclassic period.     

Learning by ‘design’: how undergraduates in Singapore learn to become engineers

ABSTRACT

In this paper, we explore the evolving norms and dispositions of creativity and enterprise of engineering students using data gathered from a newly established technology and engineering-focused university called ‘UniTech’ located in Singapore. Based on interviews with students, we seek to explain (1) what they learn, reject, adopt and appropriate; (2) the kinds of challenges they face and (3) the unexpected and serendipitous outcomes of their learning. Through an integrated engineering curriculum focusing on design, students learn to be technically competent, creative and entrepreneurial persons. This paper considers how the curriculum works as a set of formal procedures preparing students for a future ‘knowledge-based economy’ imagined to be technology-intensive, dynamic and filled with opportunities but also increasingly uncertain. We analyse how students at UniTech negotiate this design-focused curriculum where experiences of creativity, open-ended possibilities and holistic perspectives intersect with the national economic agenda of a knowledge-based economy.     

The Sources of Support for Separatism: Public Opinion in Three Soviet Republics

Abstract. The replacement of the Soviet Union by independent states rather than by a loose confederation of component republics reflects (in part) the demands for change that were being expressed by mass publics. What caused the people to reject decentralisation of authority within the existing state structure and chose rather to support movements that insisted on the establishment of independent states? We examine whether concerns about ‘discriminatory redistribution’ and ‘cultural preservation’ were more important than questions of ‘efficiency’ or ‘relative deprivation’ as motivations behind support for secession. The analysis is based upon public opinion data from Russia, Ukraine and Lithuania gathered in May of 1990 and in June of 1991. We conclude that although issues related to cultural preservation and discriminatory redistribution were foremost in the minds of separatists, concerns about efficiency and improved management in government are also relevant for understanding support for separatism.     

Local Spatial Autocorrelation Statistics: Distributional Issues and an Application

The statistics G_i(d) and G_i*(d), introduced in Getis and Ord (1992) for the study of local pattern in spatial data, are extended and their properties further explored. In particular, nonbinary weights are allowed and the statistics are related to Moran's autocorrelation statistic, I. The correlations between nearby values of the statistics are derived and verified by simulation. A Bonferroni criterion is used to approximate significance levels when testing extreme values from the set of statistics. An example of the use of the statistics is given using spatial-temporal data on the AIDS epidemic centering on San Francisco. Results indicate that in recent years the disease is intensifying in the counties surrounding the city.
