ASIANS,PACIFIC ISLANDERS,AND ETHNOBURBS IN AUCKLAND,NEW ZEALAND

ABSTRACT. Recent work on Asian ethnic minority immigrants to cities in the Anglophone Pacific Rim argues that their settlement patterns do not conform to those of earlier migrant streams. Instead of concentrating in high‐density, low‐quality, inner‐city housing, these new residents are moving directly to suburban areas where they form much less intensive concentrations—ethnoburbs—than has been typical of other culturally distinct migrant groups. We evaluate this thesis for Asian migrants in the Auckland metropolitan area, whose numbers more than quadrupled between 1991 and 2006. Their residential pattern is compared with that of Pacific Islanders also resident there, providing supporting evidence for the ethnoburb hypothesis.

EVIDENCE FOR EXPANDED MIDDLE AND LATE PLEISTOCENE GLACIER EXTENT IN NORTHWEST NELSON,NEW ZEALAND

The extent of Late Quaternary glaciation in the northwest Nelson region of New Zealand has traditionally been regarded as minor, with small‐scale valley glaciation in confined upland reaches. New geomorphological evidence, including moraines, kame terraces, till‐mantled bedrock and outwash terraces, indicate that greatly expanded valley glaciers flowed into the lowland valley system at the mouths of the Cobb‐Takaka and Anatoki drainages. The timing for this ice advance into lowland valleys is constrained by lowland landform characteristics and a single cosmogenic exposure age, suggesting Late and Middle Pleistocene ice expansion, respectively. Evidence for expanded upland ice on the Mount Arthur Tableland and adjacent areas includes trimlines, boulder trains and roche moutonées. Two cosmogenic exposure ages on upland bedrock surfaces suggest that major ice expansion occurred during MIS 3 and/or 4, while previously published exposure dating from Cobb Valley suggests large MIS 2 ice expansion as well. The inferred, markedly expanded ice left little or no clear geomorphic imprint on the Cobb–Takaka Gorge, and required temperature depression of 4–6°C with near‐modern precipitation levels.     

RECENT GLACIER ADVANCES IN NORWAY AND NEW ZEALAND: A COMPARISON OF THEIR GLACIOLOGICAL AND METEOROLOGICAL CAUSES

ABSTRACT. Norway and New Zealand both experienced recent glacial advances, commencing in the early 1980s and ceasing around 2000, which were more extensive than any other since the end of the Little Ice Age. Common to both countries, the positive glacier balances are associated with an increase in the strength of westerly atmospheric circulation which brought increased precipitation. In Norway, the changes are also associated with lower ablation season temperatures. In New Zealand, where the positive balances were distributed uniformly throughout the Southern Alps, the period of increased mass balance was coincident with a change in the Interdecadal Pacific Oscillation and an associated increase in El Niño/Southern Oscillation events. In Norway, the positive balances occurred across a strong west-east gradient with no balance increases to the continental glaciers of Scandinavia. The Norwegian advances are linked to strongly positive North Atlantic Oscillation events which caused an overall increase of precipitation in the winter accumulation season and a general shift of maximum precipitation from autumn towards winter. These cases both show the influence of atmospheric circulation on maritime glaciers.     

云南省地震与太阳活动的统计关系研究

地震与太阳活动的关系是研究活动性和地震预测中有意义的课题。作者选取云南省及周边地区1965～2006年2级以上地震为样本,使用时间序列分析方法和相关分析方法对地震与太阳黑子、耀斑的相关性进行了研究,得到中小地震为主的样本与太阳活动不相关、大地震与太阳活动存在弱相关性的结论。作者的结论与以往研究者的结论不同,原因在于以往的研究者使用大震强震为样本,样本数少,得到的结论存在不可避免的偶然性。因此在一个地方具备发生大地震的内在条件时,关注太阳活动也是十分必要的。     

硅硼镁铝矿－柱晶石－电气石组合在南极的发现

硅硼镁铝矿、柱晶石和电气石组合产于东南极拉斯曼丘陵，三种矿物相互接触并表现出特定的顺序：电气石（Ｔｒｎ１）→硅硼镁铝矿→电气石（Ｔｒｎ２）→柱晶石→电气石（Ｔｒｎ３），表明其产出是受Ｂ２Ｏ３、Ｈ２Ｏ活度的时间演化而不是空间变化所控制。这一组合的出现对于变质作用环境及过程中组分性质是一个很好的限定     

青川东河口地震遗址公园景观与旅游解说系统的构建分析

青川东河口地震遗址公园是2008年＂5.12＂汶川大地震后第一个开园的以地震遗址为主题的地质公园。地质公园内景观类型主要以滑坡、串珠状分布的堰塞湖、地热和可燃气体等为主。人文景观有民居遗址、纪念碑、遇难同胞纪念墙等。与四川其他地震遗址相比,该遗址公园的突出特点是造成当地居民重大伤亡的山地次生灾害集中分布,滑坡和泥石流遗迹保存完好。作为震遗地质公园,需要在人们凭吊和瞻仰过程中配有较好的旅游解说系统,加强解说人员的地学素养,强化地震博物馆中地震模拟的建设。现该遗址公园已成为省级地质公园,在此基础上需要通过对遗址公园的景观构建及公园旅游解说系统的建设,期望其成为国家级地质公园乃至世界级地震遗迹公园。     

THE NATURE‐CULTURE BOUNDARY AND OCEAN POLICY: GREAT BARRIER ISLAND,NEW ZEALAND*

ABSTRACT. This article analyzes New Zealand's rights‐based system of fisheries management from the perspective of local stakeholders on northern Great Barrier Island. The research identified differing perspectives through use of the concept of “boundary construction,” not only in terms of society and nature but also among societal institutions. Great Barrier Island participants exhibited significant differences, especially between staff of the local Department of Conservation and local Maori, both of whom were engaged in negotiating policy implementation at the local level. These differences expressed themselves in conceptions of both societal boundaries—the scale at which community was envisioned—and conceptions of the boundary between nature and culture. The findings confirm the need for the continued development of models of community‐based resource management as well as for the conceptual integration of society and nature in the realm of policy construction.     

ABLATION OF ICE‐CORED MORAINE IN A HUMID,MARITIME CLIMATE: FOX GLACIER,NEW ZEALAND

Depending on thickness, debris‐cover can enhance or reduce ablation, compared to bare‐ice conditions. In the geological record, hummocky moraines often represent the final product of the melt‐out of ice‐cored moraines, and the presence or absence of such moraine deposits can have paleoclimatic implications. To evaluate the effects of varying debris‐cover and climate on ice‐melt in a maritime mid‐latitude setting, an 11‐day ablation stake study was undertaken on ice‐cored moraine at Fox Glacier, on the western flank of the New Zealand Southern Alps. Ablation rates varied from 1.3 to 6.7 cm d^?1, with enhancement of melt‐rate under thin debris‐covers. Highest melt‐rates (effective thickness) occurred under debris‐cover of c. 2 cm, with ～3 cm being the debris thickness at which melt‐rates are equal to adjacent bare‐ice (critical thickness). Air temperature from nearby Franz Josef Glacier allowed for a simple degree‐day approach to ablation calculations, with regression relationships indicating air temperature is the key climatic control on melt. Digital elevation models produced from topographic surveys of the ice‐cored moraine over the following 19 months indicated that ablation rates progressively decreased over time, probably due to melt‐out of englacial debris increasing debris‐cover thickness. The morphology of the sandur appears to be strongly determined by episodic high‐magnitude fluvial flows (jökulhlaups), in conjunction with surface melt. Thus, ‘hummocky’ moraine appears to be a transient landform in this climatic setting.     

COSTS AND BENEFITS OF POLLUTION CONTROL IN PENNSYLVANIA,NEW YORK,AND NEW JERSEY, 1840–1906

ABSTRACT. Judges in Pennsylvania saw the costs and benefits of protecting people from industrial pollution quite differently from judges in New York and New Jersey between 1840 and 1906. Not only did they invoke balancing doctrine more than did judges in New York and New Jersey; but when costs and benefits were considered, Pennsylvania judges almost always concluded that the price of pollution abatement was too high to justify enjoining polluting industries. New York and New Jersey judges commonly did the reverse, acknowledging great social value and little cost to making businesses alleviate pollution. Judicial interpretation of the notions of cost and benefit mirrored the political, economic, and social conditions in each state, conditions that differed across time and place.     

GLACIATION OF MT ALLEN, STEWART ISLAND (RAKIURA): THE SOUTHERN MARGIN OF LGM GLACIATION IN NEW ZEALAND

The origin of two ridges on the eastern slopes of Mt Allen, southern Stewart Island, has remained equivocal, with differences of opinion over the exact process-mechanisms of formation. A variety of approaches was used to test a number of possible hypotheses about the origin of the ridges. These include topographic and spatial positioning, geomorphology, sedimentology and palaeoclimatological extrapolations to reconstruct two small former cirque glaciers with equilibrium line altitudes (ELAs) of c. 600 m. It would appear the two ridges reflect a glacial origin, the glaciers interpreted as forming during the Last Glacial Maximum (LGM) in New Zealand. Whilst glaciation during this time (18–19 ka) was extensive in the Southern Alps, the restricted nature of glaciation on Mt Allen suggests the low altitude restricted glaciation to niche sites on the lee side of upland areas.     

HILLS AS RESOURCES AND RESISTANCES IN SYRACUSE,NEW YORK*

In an example of what William Freudenburg and his colleagues called the “conjoint construction” of nature and society, hills may represent either assets or liabilities for urban settlement, depending on the period and the activities involved. The relationships between terrain and land use in Syracuse, New York, since the late eighteenth century fall into three major eras. The initial phase, in which settlement largely shunned the lowlands, gave way in the 1820s to one in which canals and railroads stimulated development of the lowlands and in which most land uses, save those of the classic urban fringe, avoided the uplands. A new pattern appeared in the late nineteenth century with the arrival of the electric trolley and the automobile and with provision of a municipal water supply able to reach the city's high ground. Development since then has been consistent with Ernest Burgess's 1929 model of “the poor in the valleys, the well‐to‐do on the hillslopes, and the rich on the hilltops.”

MUSLIMS,HINDUS, AND SIKHS IN THE NEW RELIGIOUS LANDSCAPE OF ENGLAND*

ABSTRACT. This article examines the dramatic changes brought to English townscapes by Islam, Hinduism, and Sikhism. These “new” religions have arrived with the large‐scale immigration and subsequent natural growth of the minority ethnic populations of Great Britain since the 1950s. The article traces the growth and distribution of these populations and religions, as well as the development of their places of worship from front‐room prayer rooms to cathedral‐scale buildings. It explores the way in which the British planning process, dedicated to preserving the traditional, has engaged with the exotic.
