title: The role of urban topography in the orientation of Greek temples: the cases of Akragas and Selinunte

authors: Hannah, Robert

subjects: Social Sciences

abstract: It is well known that the vast majority of the Greek temples of Sicily are oriented to the rising sun. However the factors which influenced the specific orientation of each temple or of each group of temples can be of various nature and no general key is actually applicable. In particular, we show here the role of local topography in orientation, trough two relevant case-studies: the temples of the urban sector of the Valley of the Temples, Akragas, and the temples of Selinunte.

title: Nitrogen losses from soils caused by Rhizobium-dependent denitrification

authors: O'Hara, G.W.

subjects: biology

abstract: Biological nitrogen fixation by the Rhizobium-legume symbiosis is of considerable agronomic importance, and most research on rhizobia is aimed at a better understanding of symbiotic nitrogen fixation (e.g. Hardy er nl.. 1979; Hardy and Silver. 1977: Hardv and Gibson. 1977). However the d I significance of early observations on denitrification by rhizobia (Rajagopalan, 1938; Ishizawa, 1939; Wilson, 1947) appears to have been overlooked; it has recently been shown to be widespread among Rhizobium species (Zablotowicz et al., 1978; Daniel ef al., 1980a. 1982) and to occur in soils under laboratory conditions (Daniel el al., 1980b). We report here field experiments showing the loss of fixed nitrogen from soils by denitrification carried out by rhizobia at rates comparable to those at which rhizobia fix nitrogen. This occurs in aerated soils, unlike previously described soil denitrification systems which are considered to be anaerobic (Knowles, 1982). Rhizobia are widespread in agricultural ecosystems (Parker et al., 1977) and an understanding of the conditions under which they denitrify may convey substantial benefits.

title: Cultural knowledge and identity for wellbeing and success: Trying to make the connections in the north of New Zealand.

authors: Hohepa, Margie Kahukura

subjects: New Zealand

abstract: This paper argues that secure cultural identity is essential to wellbeing and cultural identity is important to Māori youth participation and success. The roles of community and schools in developing secure cultural identity are increasingly complex, as both become increasingly more culturally and ethnically diverse in many parts of the world.
The paper discusses findings from student survey data from a 2 year project ‘Te Wehi Nui a Mamao: Maximising the potential of tribal marae and regional language among youth', which began in July 2008, supported by funding from New Zealand's Foundation of Research, Science and Technology. This project aims to strengthen the relevance of tribal marae and regional Maori language among Maori youth, which are identified as important to Māori cultural identity.
Inter-generational transfer of tribal marae knowledge and language is becoming more compromised. Many cultural values are defined on marae. Tribal leaders have long been concerned about disconnections between Māori youth and tribal marae, poor knowledge of regional dialect and the potential negative consequences for full participation in society. .It appears that Māori youth are disconnected from regional language dialects and marae knowledge now more than ever. Reconnecting Māori youth with these two sources of tribal identity is the key to the purpose of this project.
