Fluid flow and stability of the US continental slope offshore New Jersey from the Pleistocene to the present

We predict that portions of the New Jersey continental slope were unstable approximately 0.5 million years ago. This instability was caused by rapid sediment loading during a Pleistocene sea‐level lowstand and by flow focusing in underlying, permeable Miocene strata. The simulated instability is consistent with soft‐sediment deformation and small slumps in Pleistocene strata of the Hudson Apron. Stability of the New Jersey margin has increased since 0.3 Ma because sedimentation rate has decreased. Today, the modelled factor of safety (FS) for the upper slope is approximately 1.5 whereas in the lower slope it exceeds 3. We predict that sedimentation rate is a dominant factor on slope stability. When rapid and asymmetric loading of a highly permeable sedimentary layer occurs, the location of instability can shift seaward to regions where sedimentation rates are low. Stability calculations use pressures and effective stresses predicted by a coupled sedimentation‐fluid flow model. This hydrodynamic analysis demonstrates how the interplay of sedimentation and fluid migration affects the distribution, timing, and size of sedimentary failures.     

Fish and crayfish from the Washpool Midden site,New Zealand: Their use in determining season of occupation and prehistoric fishing methods

A method is suggested whereby modern ecological information on fish behaviour and distribution, together with commercial catch figures, may be used to assess season of occupation of archaeological sites. Monthly catch probabilities for each species are scaled by minimum numbers from prehistoric osteological assemblages to yield an overall likelihood of the fish being caught at different months of the year. A test case on two assemblages from Palliser Bay, New Zealand, suggested year-round habitation, and this was consistent with individual qualitative seasonal markers. The fishbone evidence can also be used to comment on aspects of prehistoric technology connected with marine foods, such as the use of canoes, baited traps, long line hauling, rock fishing and seine netting. In addition, the fish information substantiated subtle environmental changes which are believed to have taken place in this region.     

Water, technology, and the courtroom: negotiating reclamation policy in territorial New Mexico

Historical investigation of arid landscapes and communities in the American West has long focused on the pivotal influence of federal reclamation policy, typically characterizing its implementation as the application of scientific and technological methods to a variety of water resource management issues. This paper departs from traditional views of reclamation by highlighting the highly variable and contingent ways in which new science-based forms of water management were proposed and negotiated in specific local places with particular cultural, legal, and historical geographies. Drawing theoretically from literature on the ‘geography of science,’ the paper probes the ways in which authority for a scientific approach to water management was created, negotiated, and expressed in local and regional contexts in the Territory of New Mexico, where authoritative systems of practical resource use and administration had been in long use before the U.S. government initiated its federal water reclamation program in 1902. Specifically, the paper examines two disputes entered and argued in front of northern New Mexico’s Rio Arriba District Dourt between 1903 and 1905. By departing from the geographical and scalar perspectives typically applied to environmental histories of the West and its reclamation landscapes, this ‘microgeographical’ approach promises a fresh perspective that emphasizes the highly contingent ways in which science-based water policy was implemented in multiple and complex environments.     

Spiriferoidea (Brachiopoda) from the Early Permian Del Salto Formation of Argentina

The fossil lycopod Pleuromeia longicaulis (Burges) comb. nov. and its supposed cone Cyclostrobus sydneyensis (Walkom) Helby &; Martin 1965 are common in the Scythian to Anisian Garie and Newport Formations north of Sydney, N.S.W. P. longicaulis probably lived in extensive monodominant stands in the interdistributary bays of the ‘Gosford delta’ system, bordering a large coastal lagoon or lake. C. sydneyensis was borne as a single erect terminal cone. It was shed intact and may have floated some distance before breaking up and releasing its heterospores.

Austrostrobus ornatum Morbelli and Petriella 1973 from southern Patagonia is now included as a further species of Cyclostrobus.

The Pleuromeiaceae appear to have been facultative coastal halophytes. They probably originated in Eurasia and migrated along early Triassic shorelines, reaching eastern Australia by the mid-Scythian. The coastal habitat of the Pleuromeiaceae and other Triassic lycopods explains the biostratigraphic usefulness of the spores Aratrisporites spp., Nathorstisporites hopliticus Jung 1958, and Banksisporites pinguis (Harris) Dettmann 1961 compared with coexisting fully terrestrial fossil floras. These opportunistic lycopods appear to have expanded in times of recovery from global life crises.     

New species of Late Jurassic Australobuchia (Bivalvia) from the Murihiku Terrane,Port Waikato—Kawhia region,New Zealand

The Early Cretaceous Otway and Strzelecki Groups exposed on the southern coast of Victoria, Australia, have produced a fauna of dinosaurs that lived within the Antarctic Circle. As many as five or six species of hypsilophodontids numerically dominate the collections from there, but the rarer and more fragmentary theropod remains suggest a surprising diversity of carnivorous dinosaurs. A possible surangular and an isolated vertebra have characters considered diagnostic for Late Cretaceous oviraptorosaurs of the Northern Hemisphere. Other fossils suggest the presence of ornithomimosaurs, dromaeosaurids and neoceratopsians, and with the possible oviraptorosaur remains, challenge the widespread assumption that these animals originated on the northern continents.     

A ROOTED SENSE OF PLACE IN CROSS-CULTURAL PERSPECTIVE

Sense of place was investigated in an interpretive approach to examine how it develops; how it varies cross-culturally among modern and indigenous peoples; and how it develops among various contexts (home and environs, family, community, and culture). Individual and group interviews were conducted using questionnaires on Banks Peninsula, New Zealand (a rural, farm-based setting) with 270 residents from 1987 to 1989, with 80 out-migrants interviewed around New Zealand in 1989. The methodology was based on phenomenology, ethnography, and social surveys. Statistical analyses indicated the significance of residential status and social belonging toward the development of a sense of place. Contextual influences were found to be important from qualitative data, with traditional culture of primary importance to Maori. Both Maori and European-descent respondents with long-term residence expressed a rooted sense of place for Peninsula environs. These respondents were less residentially mobile and were often tied to the land through ancestry and/or family farms. Newcomers to the region were usually treated as outsiders (for decades). The Maori community was partially sustained by a social network that extended beyond the Peninsula. Maori sense of place was based more on their cosmology and culture, which rooted them to their tribal territory spiritually and emotionally. To counter an amoral, modernist hegemony and to move toward community sustainability, postmodernists need to consider the significance of developing a place-based ideology that links people to place through a rooted sense of place. À l'aide d'une méthode interprétative, le sentiment d'appartenance à un milieu a été étudié pour examiner la manière dont il se développe, ses variations interculturelles parmi les populations modernes et autochtones, de même que l'incidence de divers éléments, tels la résidence et son voisinage, la famille, la collectivité et la culture, sur son développement. Entre 1987 et 1989, des entretiens individuels et de groupes ont été menés, en utilisant des questionnaires, auprès de 270 résidants demeurant dans la péninsule de Banks, en Nouvelle-Zélande, et appartenant à un milieu rural essentiellement agricole. De plus, en 1989, 80 émigrants répartis sur le territoire de la Nouvelle-Zélande ont été également intervieés. Les études phénoménologiques, ethnographiques et sociales ont servi de méthode fondamentale. L'analyse statistique a révélé l'importance de la qualité de résidant et l'importance de l'appartenance sociale sur le développement du sentiment d'appartenance à un milieu. D'après les données qualitatives, l'influence environnementale est significative, et la culture traditionnelle est capitale chez les Maoris. Les répondants établis depuis longtemps, qu'ils soient de descendance européenne ou maorie, ont manifesté un sentiment profond d'appartenance à leur milieu, que représente la péninsule. Ces répondants étaient relativement stables du point de vue résidentiel et possédaient souvent une terre ancestrale ou une ferme familiale. Les nouveaux arrivants ont été habituellement traités comme des étrangers (pendant des décennies). La communauté maorie a été soutenue en partie par un réseau social qui s'est étendu au-delà de la péninsule. Chez ce peuple, le sentiment d'appartenance au milieu s'appuie davantage sur la cosmologie et la culture, ce qui crée des liens spirituels et affectifs entre ces gens et leur territoire tribal. Pour s'opposer à l'hégémonie amorale et moderniste, et pour s'orienter vers la viabilité des collectivités, les post-modernistes doivent se rendre compte de l'importance d'élaborer une idéologie axée sur le milieu qui lie les gens par un sentiment profond d'appartenance.     

Mothering,digital media and emotional geographies in Hamilton,Aotearoa New Zealand

This article traces a line between two literatures that can usefully be drawn into deeper conversation: geographies of digital media, and geographies of emotion. Its broad theoretical aim is to ascertain what insights might be gleaned by increasingly bringing together these two literatures. The more specific and primary aim, however, is an empirical one and that is to offer a materially grounded example of 35 mothers who live in Hamilton, Aotearoa New Zealand who use digital media to communicate with their children. Particular attention is paid to the capacities of different digital media, both individually and combined, to help facilitate, but certainly not guarantee, different emotions. The research is informed by a feminist geographical reading of theories of digital media and emotion. Findings illustrate that increasingly mothers are making use of digital media, both singularly and collectively, to increase the chances of a particular desired emotional outcome with their child or children. This article concludes that bodies, devices, screens, sounds and images comingle to mediate emotions over time and space.     

The relationship between children's perceptions of the natural environment and their subjective well-being

The overarching aim of the study was to ascertain the relationship between children's perceptions of the natural environment and their subjective well-being. More specifically the study aimed to fit a structural model depicting the nature of the relationship between children's environmental views and their global, and domain-specific life satisfaction. The sample included 1004 twelve-year-old participants randomly selected from 15 primary schools in Cape Town, South Africa. The measuring instrument included the New Ecological Paradigm (NEP) Scale for children, the Students' Life Satisfaction Scale and the Personal Well-Being Index-School Children. Confirmatory factor analysis was used to test the validity of the NEP Scale which showed appropriate fit structure. A good fit structure was also found for the overall structural equation model. However, the overall model showed that children's environmental views were not related to their global life and domain-specific life satisfaction. At a foundational level, more research is required to allow for a better understanding of how children in differing circumstances construct and assign meaning to nature, and what their perceptions of nature are before we can begin to ask them when, how or why they engage in nature.

The estimation of live fish size from archaeological cranial bones of the New Zealand blue cod Parapercis colias

Twenty-four measurements were taken on five of the paired cranial bones and the otoliths of a modern sample of 177 blue cod. Parapercis colias. Regression analysis was performed on these measurements to estimate live fork length and ungutted weight. A number of regression models were examined (linear, logarithmic, exponential and power curve) to work out the optimum estimator for each bone measurement. It was found that live fork length of this species can be estimated with a standard error of less than ±28 mm, and the weight to less than ±140 g. Coefficients are provided for 48 equations linking bone size to live characteristics. This is followed by a study of blue cod from an archaeological site at Waihora in the Chatham Islands. Measurements were made on 8036 archaeological bones with a minimum number of individuals of 2547. It was found that the blue cod catch had near normal characteristics, with a mean fork length of 327 mm and SD of 57 mm. The mean body weight was estimated at 569 g. The usable meat weight represented by these fish is estimated to be 1.0 t. © 1997 John Wiley & Sons, Ltd.
