title: Complexes of η⁵, κP-cyclopentadienyl-phosphine ligands by chelate-assisted dehydrofluorinative coupling; the coupling of bis{bis(pentafluorophenyl)phosphino}methane to η⁵-pentamethylcyclopentadienyl in a rhodium complex

authors: Marr, Andrew C.

subjects: Cyclopentadienyl ligands

abstract: The reaction between [{(η⁵-C₅Me₅)RhCl(μ-Cl)}₂] and (C₆F₅)₂PCH₂P(C₆F₅)₂ in refluxing benzene yields the singly linked complex [{(η⁵,κP-C₅Me₄ CH₂C₆F₄-2-P(C₆F₅)CH₂P(C₆F₅)₂)}RhCl₂] in which only one phosphorus atom is coordinated to the rhodium.

title: Patterns of past and recent conversion of indigenous grasslands in the South Island, New Zealand

authors: Weeks, Emily Sherra

subjects: Land tenure

abstract: We used recent satellite imagery to quantify the extent, type, and rate of conversion of remaining indigenous grasslands in the inland eastern South Island of New Zealand in recent years. We describe the pattern of conversion in relation to national classifications of land use capability and land environments, and ecological and administrative districts and regions. We show that although large areas of indigenous grasslands remain, grassland loss has been ongoing. Indigenous grassland was reduced in the study area by 3% (70 200 ha) between 1990 and 2008. Almost two-thirds of post-1990 conversion occurred in threatened environments with less than 30% of indigenous cover remaining, primarily in the Waitaki, Mackenzie and Central Otago administrative districts. This conversion occurred primarily on non-arable land. In the Mackenzie and Waitaki districts the rate of conversion in 2001-2008 was approximately twice that in 1990-2001. Opportunities to protect more of the full range of indigenous grasslands lie with the continuing tenure review process in these districts.

title: Evidence of swarm intelligence in collective cultures: Identifying the use of the swarm goal directive of productivity in Pacific organisation systems as well as getween genders

authors: Arun, Natalie M.

subjects: Maori

abstract: Intrigued by the existence of societies outside that of the human population, scientists have ventured to study social aggregations within insects to seek insights on effective colonizing. The most popular of these social aggregations are colonies of ants and bees. In studying these groups of social insects researchers have developed algorithms loosely termed swarm intelligence that increase work efficiency within businesses and other social organizations (Bonabeau & Meyer, 2001). A subsequent proliferation of research in surrounding fields has allowed for investigation of key variables that improve work on a global scale (Bonabeau & Meyer, 2001). James Kennedy (1999), an initiator of swarm research, has suggested that there is a high correlation between systems that rely on each other for information and greater task accomplishment.
