Abstract (sommario):

The main objective of this study was to describe the psychiatric disorders seen in patients presenting for treatment in rural New South Wales. The patients were seen primarily in the community, in both public and private practice, but also in the local base hospital and prison. Seven hundred and seven patients were consecutively examined during the study period. The results of this study were compared with a previous Australia-wide study to identify specific disorders that were more prevalent in rural areas. Alcohol abuse and dependence stood out as being much more prevalent. Life problems such as domestic violence, sexual assault, and incest occurred commonly in women referred for psychiatric assessment. More than ten percent of the study patients were children aged under 17, who had similar prevalence rates of the various psychiatric disorders to a national comparison. It is concluded that alcohol abuse is very common in rural New South Wales, particularly in men, although there are also high rates in women, and this is probably related, in part at least, to the high rates of domestic violence, sexual assault and incest. It appears probable that there is a cycle of alcohol abuse in men leading to domestic violence and sexual abuse in women and children. This may contribute to the latter becoming anxious and depressed. The rates of the major functional psychiatric disorders were similar to those seen nationally. There is a great need for the maldistribution of psychiatrists between metropolitan and rural areas to be addressed.

Abstract (sommario):

This thesis uses a translational research approach and combines theoretical, empirical and experiential evidence to explore four key issues that provide further direction to current efforts to reduce lead exposure in Broken Hill, and more generally to improve management of environmental health risks in the community setting. A theoretical review argues for an adaptive response to program development, recognising that the solution to the problem is not straightforward. The review indicated the need for multi-pronged strategies including both population-based approaches and strategies focussing on particular risk groups. Unintended negative consequences must be scanned for and managed so as to ensure a positive benefit : harm ratio is maintained. A qualitative, interview based case study of successful lead exposure reduction programs identified the need for an accurate understanding of sources and pathways of exposure, which may need an iterative approach; effective control of those sources and pathways, adequate funding to undertake the work and active cooperation of relevant stakeholders. A qualitative, interview based case study of the Broken Hill Lead Reference Group found there was broad agreement as to what was required to further reduce lead exposure but that lack of recognition of constraints other organisations faced and overall lack of resources (funding and leadership) within the LRG significantly inhibited collaboration across the group and efforts to reduce lead exposure. Improving collaboration and leadership within this Group is necessary in the long term to reduce lead exposure. A before-after study of changes in participation in blood lead screening found that changing from venous to capillary screening and improving convenience both increased screening, and showed that restructuring services in response to community concern can effectively increase participation. A $13 million, five year program to reduce lead exposure in Broken Hill was established in 2015; considerably more funding is likely to be required.

Abstract (sommario):

The Broken Hill deposit, Aggeneys, is a metamorphosed stratiform Cu-Pb-Zn-Ag sulphide deposit situated in the mid-Proterozoic supracrustal sequence of the Bushmanland Subprovince in the Namaqualand Metamorphic Complex. The deposit comprises two superposed orebodies, each consisting mainly of massive sulphide lenses and iron formation which are hosted within a metapelitic schist close to major quartzite horizons. This study is concerned with the tectonically lower orebody (LOB). The iron formation is magnetite-rich and contains varying proportions of (Fe,Mn)-rich silicates (garnet, amphibole, olivine, orthopyroxene, pyroxenoid), quartz and Cu-Pb-Zn-sulphides. These minerals occur in mm- to 5 cm-thick bands and are often traceable over tens of metres. The well preserved banding is considered to represent bedding. Five different varieties of silicate-rich mesobands in the iron formation can be distinguished based on the predominant mineral assemblage: (a) amphibole-olivine-quartz +/- garnet, (b) amphibole-quartz, (c) garnet-apatite-quartz +/- amphibole, (d) garnet-apatite-quartzorthopyroxene, (e) pyroxferroite-quartz +/- amphibole and (f) quartz. These rocks all contain magnetite, and Ba-rich biotite is common but is not always present.

Abstract (sommario):

The historiography of Australian racism has principally "blamed" the labour movement for the existence of the White Australia policy and racist responses to the presence of migrant workers. This study argues that the motivations behind ruling class agitation for the White Australia policy have never been satisfactorily analysed. To address this omission, the role of the Returned and Services League of Australia (RSL) in race relations is examined. As an elite-dominated, cross-class organisation with links to every section of society, it is argued that the RSL was a significant agitator for migrant exclusion and white unity in the interwar period. The thesis employs case studies, oral history and qualitative assessment of various written sources, such as newspapers, archival records and secondary material, in order to plot the dynamics of racist ideology in two major mining centres in the interwar period. The results suggest that, although labour organisations were influenced by racist ideas and frequently protested against the presence of migrant workers, it was also true that mining employers had a material interest in sowing racial division in the workplaces they controlled. The study concludes that labour movement responses to migrant labour incorporated a range of different strategies, from demands for racist exclusion to moves towards international solidarity. It also reveals examples of local and migrant workers living, working, playing and striking together in ways that contradict the dominant view of perpetual tension between workers of different nationalities. Lastly, the case studies demonstrate that local employers actively encouraged racial division in the workplace as a bulwark against industrial militancy.

Abstract (sommario):

Magister Artium - MA
The rich corpus of postcolonial scholarly engagement on indigenous intermediaries, interpreters, clerks and assistants has a made a strong argument for the active participation of African agents in social scientific knowledge production on Africa. This literature has highlighted the complex and negotiated nature of fieldwork in African anthropology. While this literature has begun to deepen our understanding of the knowledge work of anthropologists and their research assistants, it has not adequately explored the relationship between anthropologists and informants in what one scholar has recently called ‘a triangulation of relationships’ between the anthropologist, the assistant and the informant. This research project proposes to explore these relationships in a detailed case study: that of the British anthropologist Godfrey Wilson (1908–1944), his interpreter Zachariah Mawere, and three primary informants, during three years of pioneering research into the effects of migrant labour at Broken Hill, Northern Rhodesia (Zambia) between 1938 and 1941. Using a close textual reading and detailed analysis of Wilsons Bemba and English fieldnotes held in the Godfrey and Monica Wilson collection at the University of Cape Town’s African Studies Library, the study will apply a micro-historical and biographical approach. It will seek to reconstruct the biographies and anthropological contributions of one interpreter and three central Bemba informants in order to explore the micro-politics of knowledge production in African anthropology.

Abstract (sommario):

Zinkgruvan is a stratiform Zn-Pb-Ag and Cu sulphide deposit hosted by Paleoproterozoic strata in southern Bergslagen, Sweden. The deposit underwent medium-high grade regional metamorphism during the Svecokarelian orogeny, including partial melting of the host succession. Subordinate zones of semi-massive to massive magnetite and Fe-rich skarns occur in marble stratigraphically below the stratiform Zn-Pb-Ag ore but have so far not been described in detail in the scientific literature. This thesis presents results from detailed geological drill core logging, light optical microscopy (LOM) and scanning electron microscopy (SEM), which have been integrated with results from electron microprobe analysis (FE-EMPA) and whole-rock lithogeochemical analysis to provide a comprehensive description of the magnetite mineralization. Samples from the formerly mined magnetite deposits Västerby, Garpa and Åmme - distal to Zinkgruvan - have also been studied to allow for a comparison. The combined dataset has been used to 1) discuss the genesis of the magnetite mineralizations, including their relationship to base metal sulphide mineralization, and 2) evaluate potential vectors to Zn-Pb-Ag and Cu mineralization based on variations in the magnetite deposits. The semi-massive to massive magnetite, adjacent and associated Fe-rich skarn at Zinkgruvan are located in the stratigraphic upper part of the marble host. Three different varieties of magnetite mineralization can be defined: 1) semi-massive to massive magnetite mineralization in marble, 2) magnetite-bearing veins and 3) retrograde magnetite after olivine. Detailed optical microscopy has revealed a positive spatial correlation between aluminium spinel, apatite, magnetite and graphite. Semi-massive to massive magnetite mineralization at Zinkgruvan is enriched in P2O5, ΣREELa-Lu and Mn relative to a carbonate precursor. A positive correlation exists between P2O5 and ∑REELa-Lu, suggesting apatite and monazite are the primary REE-bearing minerals. The fact that the samples with highest P2O5 and ∑REELa-Lu are all Fe-rich rocks suggest the enrichment of the latter is related to the event which formed the Fe mineralization. Magnetite mineralization from the historic iron mines NW of Zinkgruvan share several key attributes with magnetite mineralization at Zinkgruvan. These include: 1) magnetite is the only iron oxide, 2) lithological and mineralogical similarities, including spatial association with marble, 3) equally high whole-rock Fe content, 4) equally high Mn (1-4 wt.% MnO), 5) equally high Eu anomalies (Eu/Eu* = 1.1- 2.8, avg. 1.75), and 6) local presence of sphalerite mineralization. Bending of the tectonic foliation from c. E-W to NW in the western part of Zinkgruvan suggest these magnetite mineralizations may be located along the same trend as those at Zinkgruvan. The normal calc-silicate mineralogy in Zinkgruvan marble (e.g. diopside, forsterite, phlogopite) can be explained by prograde regional metamorphic reactions between silicates and dolomite or calcite in impure carbonate rocks with a variable content of detrital siliciclastic and volcaniclastic material. However, the stratabound magnetite mineralization and associated Fe-rich skarns cannot be fully accounted for by this model. It is plausible that the Fe-rich skarns can be explained by similar reactions but involving more Fe-rich carbonates (ferrodolomite, ankerite, siderite). In the absence of quartz, siderite is known to thermally decompose into magnetite and graphite at temperatures above 465° C, whereby siderite-rich rocks may have been precursor to the semi-massive to massive magnetite mineralization. A recent genetic model suggests that the ore-forming fluids which formed Zinkgruvan where similar to those which formed McArthur-type SEDEX deposits. The presented results are consistent with this model, since e.g. siderite is a common alteration mineral in alteration envelopes to such deposits. Hence, magnetite mineralization, Zn-Pb-Ag and Cu-ore may all be related to the same pre-metamorphic hydrothermal system. The current genetic model places the magnetite mineralization at Zinkgruvan proximal to a fossil hydrothermal vent zone (the Burkland discontinuity). It is plausible that the magnetite mineralization mined at surface lay along the northern continuation of the Burkland discontinuity. Based on the assumption that the Burkland Cu-mineralization is most proximal and the old iron mines at Åmme are most distal along this structure, variations in whole-rock lithogeochemistry, mineral chemistry and mineralogy have been used to define nine vectors to economic Zn-Pb-Ag and Cu ore as is mined at Zinkgruvan.

Abstract (sommario):

The research in this study consisted of two strands. The first consists of noble metal geochemical studies and the second involves base metal supergene processes. The precious metal geochemistry carried out in the scope of this thesis involves palladium and tellurium geochemistry, surface chemistry studies of palladium-bismuth- and tellarium-bearing synthetic minerals, and electrochemical determinations of the inactivity of a variety of primary telluride minerals and alloys. Two new minerals have been found in deposits near Broken Hill, N.S.W. The second section of the research concerns itself with supergene processes in two copper-bearing orebodies. This was carried out by designing a method utilising solution equilibria to predict whether secondary mineral species are precipitating or dissolving in the supergene zones of the Girilambone, N.S.W. and North Mungana, Qld. orebodies. Results found could be used to develop new geochemical prospecting methods in the regions discussed.

Abstract (sommario):

Strong mortars from the tower of the Cerreto Ciampoli castle (Siena, Italy)Known since the eleventh century, the castle of Cerreto Ciampoli was one of the main fortifications of the ancient Republic of Siena (Tuscany, Italy). The magnificent ruins, located on the top of a hill overlooking the Chianti Mountains, consist of two city walls, a door, a church, the remains of some rooms and a mighty tower lying on the ground broken up into five sections of several meters in length. The present study is focused on the analysis of the mineralogical-petrographic and chemical features of the sack and the bedding mortars of the tower, and it is aimed at understanding the exceptional qualities of these mortars that, during the collapse of the artifact, prevented the tower from shattering into smaller pieces. The tenacity of these mortars appears to be the result of the concurrence of more expedients, such as the choice of well-selected materials (hydraulic limes obtained from the local Alberese limestone, sandy aggregates from well-rinsed river sands with a high silicoclastic component) and the use of particular technical methods (i.e. hot lime technique).

The new global catalog of craters for Mercury, containing morphological and morphometric information, includes data onthe location (latitude, longitude), diameter, depth and such features of craters as the degree of preservation of the rampart,the presence of terraces and collapses on the inner slope, the presence of peaks, hills and ridges, cracks and chains, thenature of the bottom, lava at the bottom, the ray system, the nature of the underlying surface. The new catalog is basedon measurements of the coordinates and diameters of craters carried out at Brown University (USA) for craters with adiameter of 20 km or more and is supplemented by craters with diameters of 10–20 km. To describe the morphologicalfeatures of craters we used the methodology developed in SAI MSU.

Abstract (sommario):

Abstract We present a suite of numerical simulations of two-phase flow through a 2D model of a porous medium using the Rothman-Keller Lattice Boltzmann Method to study the effect of viscous fingering on the recovery factor as a function of viscosity ratio and wetting angle. This suite involves simulations spanning wetting angles from non-wetting to perfectly wetting and viscosity ratios spanning from 0.01 through 100. Each simulation is initialized with a porous model that is fully saturated with a "blue" fluid, and a "red" fluid is then injected from the left. The simulation parameters are set such that the capillary number is 10, well above the threshold for viscous fingering, and with a Reynolds number of 0.2 which is well below the transition to turbulence and small enough such that inertial effects are negligible. Each simulation involves the "red" fluid being injected from the left at a constant rate such in accord with the specified capillary number and Reynolds number until the red fluid breaks through the right side of the model. As expected, the dominant effect is the viscosity ratio, with narrow tendrils (viscous fingering) occurring for small viscosity ratios with M ≪ 1, and an almost linear front occurring for viscosity ratios above unity. The wetting angle is found to have a more subtle and complicated role. For low wetting angles (highly wetting injected fluids), the finger morphology is more rounded whereas for high wetting angles, the fingers become narrow. The effect of wettability on saturation (recovery factor) is more complex than the expected increase in recovery factor as the wetting angle is decreased, with specific wetting angles at certain viscosity ratios that optimize yield. This complex phase space landscape with hills, valleys and ridges suggests the dynamics of flow has a complex relationship with the geometry of the medium and hydrodynamical parameters, and hence recovery factors. This kind of behavior potentially has immense significance to Enhanced Oil Recovery (EOR). For the case of low viscosity ratio, the flow after breakthrough is localized mainly through narrow fingers but these evolve and broaden and the saturation continues to increase albeit at a reduced rate. For this reason, the recovery factor continues to increase after breakthrough and approaches over 90% after 10 times the breakthrough time.

Abstract (sommario):

Recently in 2021the 11th office of the Fine Arts Department, Songkhla has reported their annual excavations in Trang Province that archaeologists have found some set of rice while excavation in process namely,1) Khao Kurum Archaeological Site, Huai Yod District and 2) Napala Archaeological Site, Muang District. The artifacts which were found associated with the rice grains on the habitation layer consisted of potsherds, animal bones, grindstone, beads, etc. The grains of rice are short and brown in colour which is examined as carbonized since the beginning at its first left. The primary examination by archaeologists has classified the rice of Napala Archaeological Site as short grain of probably Orysa sativa (Indica or Aus) rice. AMS Radiocarbon dating by Beta Analytic Testing Laboratory shows the AMS standard results and calibration dating of charred material measured radiocarbon age:1440±30BP. Because of their geographical location, both sites are incredibly located on one side of the hill slope, where they were suitable for habitat and plantation, especially tiny paddy fields and farms with sufficient water supply either small stream or well. The found rice, which now still grows uphill, probably called ‘Khao rai’ needs less water or no marsh. Comparative study of ethnographic “Atong” 1 of 12 sub-tribes of the “Garos” Tibeto-Burman in Meghalaya, India which originated slash-and-burnt socio-groups, have shown an interest in growing rice activity. According to their ritual ceremony for planting of paddy, other grain, and seeds takes place. There are many ritualistic offerings of rice such as (1) flattened rice by asking for permission to cultivate the land from the first harvested paddy in May. (2) After the harvesting in September or October, the 1st ceremony of the agricultural year is a thanksgiving ceremony to mark the end of a period of toil in the fields and harvesting of bumper crops, which is probably the most important festival of the Garos locally called “Maidan syla” meant to celebrate the after-harvested festival or burnt rice festival. Their 2nd ceremony is to revive the monsoon clouds. People throw cooked rice on the floor to symbolize hailstones. Noticing the rice, were probably the assemblage of “Khao San Dam” in many activities of these ceremonies, that is the archaeological evidence found in Khao Kurum and Napala Archaeological Sites. In the Southern part of Thailand, once the crops have already cultivated, people celebrate to welcome their outcrops most probably at the end of September to October and mark their end of plantation before the monsoon come. People prepare 4 main rice desserts put together with other necessity stuffs in the “hmrub” special large containers and donate to the ancestors through Buddhist ceremony. Though archaeological evidence shows that southern peninsular was where the migrants from the west especially India origins, who shared same habitat of hillslope, might brought their different traditions through both land trans-peninsular and sea routes then settled down inner western or eastern coast since prehistoric times. The beliefs in animism might belong to some other western migrants and with having “hmrub” is one of their unique cultural characteristic material and tradition remain. Once they settled down then converged to Buddhism, the ritual ceremony may be changed due to religion, but tradition remains the same today, that is, Bun Duean Sib on the 10th of the lunar month or September-October.

Abstract (sommario):

Invasive exotic plant (IEP) species are one of the biggest threats to natural ecosystem integrity and biodiversity, and controlling them is a high priority for the National Park Service. The Northern Colorado Plateau Network (NCPN) selected the early detection of IEPs as one of 11 monitoring protocols to be implemented as part of its long-term monitoring program. This report represents work completed during the 2021 field season at Fossil Butte National Monument (NM). From June 26 to 29, 2021, we recorded a total of 12 different priority IEP species during monitoring. A total of 763 priority IEP patches were recorded along 61.9 kilometers (38.5 mi) of 22 monitoring routes. Summer cypress (Bassia scoparia) was detected for the first time on monitoring routes along the Main Park Road. The highest densities of IEP patches were detected in several drainages and one trail: Sage Grouse Lek Drainage (32.7 patches/km), East Red Hill Drainage (19.4/km), Moose Bones Canyon (19.4/km), Main Park Road (19.0/km), West Fork Chicken Creek (17.6/km), Chicken Creek (15.0/km), Smallpox Creek (13.5/km) and the Historic Quarry Trail (11.1/km). The Fossil Butte Northwest, Wasatch Saddle, and North Dam Fork of Chicken Creek drainages were the only routes free of priority IEPs in 2021. Cheatgrass (Bromus tectorum), creeping foxtail (Alopecurus arundi-naceus), and Japanese brome (Bromus japonicus) were the most widespread species. Creeping foxtail continues to increase parkwide and along the Main Park Road and southern drainages. The two brome species have declined somewhat since 2018, but these species can fluctuate widely based on precipitation. Flixweed (Descurainia sophia), whitetop (Cardaria sp.), and quackgrass (Elymus repens) all appear to have declined since 2018 and their previous highs in earlier years. Control efforts by park staff are likely helping to prevent some IEP increases in the park. Network staff plan to return to Fossil Butte NM for an eighth round of monitoring in 2023.

Abstract (sommario):

Climate and hydrology are major drivers of ecosystems. They dramatically shape ecosystem structure and function, particularly in arid and semi-arid ecosystems. Understanding changes in climate, groundwater, and water quality and quantity is central to assessing the condition of park biota and key cultural resources. The Sonoran Desert Network collects data on climate, groundwater, and surface water at 11 National Park Service units in south-ern Arizona and New Mexico. This report provides an integrated look at climate, groundwater, and springs conditions at Saguaro National Park (NP) during water year 2019 (October 2018–September 2019). Annual rainfall in the Rincon Mountain District was 27.36" (69.49 cm) at the Mica Mountain RAWS station and 12.89" (32.74 cm) at the Desert Research Learning Center Davis station. February was the wettest month, accounting for nearly one-quarter of the annual rainfall at both stations. Each station recorded extreme precipitation events (>1") on three days. Mean monthly maximum and minimum air temperatures were 25.6°F (-3.6°C) and 78.1°F (25.6°C), respectively, at the Mica Mountain station, and 37.7°F (3.2°C) and 102.3°F (39.1°C), respectively, at the Desert Research Learning Center station. Overall temperatures in WY2019 were cooler than the mean for the entire record. The reconnaissance drought index for the Mica Mountain station indicated wetter conditions than average in WY2019. Both of the park’s NOAA COOP stations (one in each district) had large data gaps, partially due to the 35-day federal government shutdown in December and January. For this reason, climate conditions for the Tucson Mountain District are not reported. The mean groundwater level at well WSW-1 in WY2019 was higher than the mean for WY2018. The water level has generally been increasing since 2005, reflecting the continued aquifer recovery since the Central Avra Valley Storage and Recovery Project came online, recharging Central Arizona Project water. Water levels at the Red Hills well generally de-clined starting in fall WY2019, continuing through spring. Monsoon storms led to rapid water level increases. Peak water level occurred on September 18. The Madrona Pack Base well water level in WY2019 remained above 10 feet (3.05 m) below measuring point (bmp) in the fall and winter, followed by a steep decline starting in May and continuing until the end of September, when the water level rebounded following a three-day rain event. The high-est water level was recorded on February 15. Median water levels in the wells in the middle reach of Rincon Creek in WY2019 were higher than the medians for WY2018 (+0.18–0.68 ft/0.05–0.21 m), but still generally lower than 6.6 feet (2 m) bgs, the mean depth-to-water required to sustain juvenile cottonwood and willow trees. RC-7 was dry in June–September, and RC-4 was dry in only September. RC-5, RC-6 and Well 633106 did not go dry, and varied approximately 3–4 feet (1 m). Eleven springs were monitored in the Rincon Mountain District in WY2019. Most springs had relatively few indications of anthropogenic or natural disturbance. Anthropogenic disturbance included spring boxes or other modifications to flow. Examples of natural disturbance included game trails and scat. In addition, several sites exhibited slight disturbance from fires (e.g., burned woody debris and adjacent fire-scarred trees) and evidence of high-flow events. Crews observed 1–7 taxa of facultative/obligate wetland plants and 0–3 invasive non-native species at each spring. Across the springs, crews observed four non-native plant species: rose natal grass (Melinis repens), Kentucky bluegrass (Poa pratensis), crimson fountaingrass (Cenchrus setaceus), and red brome (Bromus rubens). Baseline data on water quality and chemistry were collected at all springs. It is likely that that all springs had surface water for at least some part of WY2019. However, temperature sensors to estimate surface water persistence failed...
