Mapping glider habitat in dry eucalypt forests for Montreal Process indicator 1.1: Fragmentation of forest types

Accurate habitat mapping is critical to landscape ecological studies such as required for developing and testing Montreal Process indicator 1.1e, fragmentation of forest types. This task poses a major challenge to remote sensing, especially in mixedspecies, variable-age forests such as dry eucalypt forests of subtropical eastern Australia. In this paper, we apply an innovative approach that uses a small section of one-metre resolution airborne data to calibrate a moderate spatial resolution model (30 m resolution; scale 1:50 000) based on Landsat Thematic Mapper data to estimate canopy structural properties in St Marys State Forest, near Maryborough, south-eastern Queensland. The approach applies an image-processing model that assumes each image pixel is significantly larger than individual tree crowns and gaps to estimate crown-cover percentage, stem density and mean crown diameter. These parameters were classified into three discrete habitat classes to match the ecology of four exudivorous arboreal species (yellowbellied glider Petaurus australis, sugar glider P. breviceps, squirrel glider P. norfolcensis , and feathertail glider Acrobates pygmaeus), and one folivorous arboreal marsupial, the greater glider Petauroides volans. These species were targeted due to the known ecological preference for old trees with hollows, and differences in their home range requirements. The overall mapping accuracy, visually assessed against transects (n = 93) interpreted from a digital orthophoto and validated in the field, was 79% (KHAT statistic = 0.72). The KHAT statistic serves as an indicator of the extent that the percentage correct values of the error matrix are due to ‘true’ agreement verses ‘chance’ agreement. This means that we are able to reliably report on the effect of habitat loss on target species, especially those with a large home range size (e.g. yellow-bellied glider). However, the classified habitat map failed to accurately capture the spatial patterning (e.g. patch size and shape) of stands with a trace or sub-dominance of senescent trees. This outcome makes the reporting of the effects of habitat fragmentation more problematic, especially for species with a small home range size (e.g. feathertail glider). With further model refinement and validation, however, this moderateresolution approach offers an important, cost eff e c t i v e advancement in mapping the age of dry eucalypt forests in the region.

Globalization and women in southeast Asian higher education management

This paper draws on data from a group case study of women in higher education management in Hong Kong, Singapore, Malaysia, and Thailand. I investigate culture-specific dimensions of what the Western literature has conceptualized as glass ceiling impediments to women's career advancement in higher education. I frame my argument within recent debates about globalization and glocalization to show how the push-pull and disjunctive dynamics of globalization are experienced in local sites by social actors who traverse global flows and yet remain tethered to local discourses, values, and practices. All of the women in this study were trained in Western universities and are fluent English speakers, world-class experts in their fields, well versed with equity discourses, and globally connected on international nongovernment organization (NGO) and academic circuits. They are indeed global cosmopolitans. And yet their testimonies indicate that so-called Asian values and religious-cultural ideologies demand the enactment of a specific construct of Asian femininity that militates against meritocratic equality and academic career aspirations to senior management levels. Despite the global nature of the University and increasing global flows of academics, students, and knowledge, the politics of academic glass ceilings are not universal but always locally inflected with cultural values and norms. As such, the politics of disadvantage for women in higher education require local and situated analyses in the context of global patterns of the educational status Of women and the changing nature of higher education.

Insights into collisional magmatism from isotopic fingerprints of melting reactions

Piston-cylinder experiments in the granite system demonstrate that a variety of isotopically distinct melts can arise from progressive melting of a single source. The relation between the isotopic composition of Sr and the stoichiometry of the observed melting reactions suggests that isotopic signatures of anatectic magmas can be used to infer melting reactions in natural systems. Our results also indicate that distinct episodes of dehydration and fluid-fluxed melting of a single, metapelitic source region may have contributed to the bimodal geochemistry of crustally derived leucogranites of the Himalayan orogen.

A review of guidelines and standards for telemedicine

We conducted a review to establish the range and scope of current telemedicine guidelines and standards. Published guidelines were identified by searching the Medline and Telemedicine Information Exchange (TIE) databases, and by performing a Google search using the term 'telemedicine guidelines'. Three types of guidelines were identified, namely clinical, operational and technical. Clinical guidelines included those for teleradiology, telepsychiatry, home telenursing, minor injuries telemedicine, surgical telemedicine, teledermatology and telepathology. Operational guidelines included those for email communication, Internet access and videoconferencing. Technical guidelines included those from the American Telemedicine Association and the US Office for the Advancement of Telehealth. The main standards relevant to telemedicine include those of the International Telecommunication Union and the DICOM standard. The scarcity of guidelines and standards suggests that telemedicine is not yet near to routine use. If an international telemedicine organization were to take responsibility for defining guidelines, under the direction of clinicians with appropriate telemedicine experience, this might speed up their development.

No Major Schizophrenia Locus Detected on Chromosome 1q in a Large Multicenter Sample

Reports of substantial evidence for genetic linkage of schizophrenia to chromosome 1q were evaluated by genotyping 16 DNA markers across 107 centimorgans of this chromosome in a multicenter sample of 779 informative schizophrenia pedigrees. No significant evidence was observed for such linkage, nor for heterogeneity in allele sharing among the eight individual samples. Separate analyses of European-origin families, recessive models of inheritance, and families with larger numbers of affected cases also failed to produce significant evidence for linkage. If schizophrenia susceptibility genes are present on chromosome 1q, their population-wide genetic effects are likely to be small.

Critical comparison of Julius Kruttschnitt Mineral Research Centre (JKMRC) blast fragmentation models

Blast fragmentation can have a significant impact on the profitability of a mine. An optimum run of mine (ROM) size distribution is required to maximise the performance of downstream processes. If this fragmentation size distribution can be modelled and controlled, the operation will have made a significant advancement towards improving its performance. Blast fragmentation modelling is an important step in Mine to Mill™ optimisation. It allows the estimation of blast fragmentation distributions for a number of different rock mass, blast geometry, and explosive parameters. These distributions can then be modelled in downstream mining and milling processes to determine the optimum blast design. When a blast hole is detonated rock breakage occurs in two different stress regions - compressive and tensile. In the-first region, compressive stress waves form a 'crushed zone' directly adjacent to the blast hole. The second region, termed the 'cracked zone', occurs outside the crush one. The widely used Kuz-Ram model does not recognise these two blast regions. In the Kuz-Ram model the mean fragment size from the blast is approximated and is then used to estimate the remaining size distribution. Experience has shown that this model predicts the coarse end reasonably accurately, but it can significantly underestimate the amount of fines generated. As part of the Australian Mineral Industries Research Association (AMIRA) P483A Mine to Mill™ project, the Two-Component Model (TCM) and Crush Zone Model (CZM), developed by the Julius Kruttschnitt Mineral Research Centre (JKMRC), were compared and evaluated to measured ROM fragmentation distributions. An important criteria for this comparison was the variation of model results from measured ROM in the-fine to intermediate section (1-100 mm) of the fragmentation curve. This region of the distribution is important for Mine to Mill™ optimisation. The comparison of modelled and Split ROM fragmentation distributions has been conducted in harder ores (UCS greater than 80 MPa). Further work involves modelling softer ores. The comparisons will be continued with future site surveys to increase confidence in the comparison of the CZM and TCM to Split results. Stochastic fragmentation modelling will then be conducted to take into account variation of input parameters. A window of possible fragmentation distributions can be compared to those obtained by Split . Following this work, an improved fragmentation model will be developed in response to these findings.

A questão do género em Moçambique: contributo para uma análise da sua problemática

RESUMO:O desenvolvimento entendido como um processo político, económico e social, visando uma melhoria constante do bem-estar de toda a população, requer a alocação e utilização de recursos para benefício social e económico da sociedade. Porém, em Moçambique, neste processo, o crescimento e progressão dos grupos sociais ainda é desigual, ocorrendo uma certa marginalização e menor participação nos processos de tomada de decisão, das mulheres e dos grupos desfavorecidos. O presente estudo, subordinado ao tema: “A Questão do Género em Moçambique: Contributo para uma análise da sua problemática”, procurou compreender a importância e o contributo das mulheres moçambicanas inseridas em diferentes áreas de desenvolvimento e o seu empoderamento. O estudo foi centrado nas diversas formas de luta e de intervenção contra a pobreza e a exclusão social. A metodologia do presente trabalho consistiu numa pesquisa empírica através da observação participante, onde foram feitas entrevistas, utilizando guiões pré-elaborados que permitiram recolher os perfis sociológicos das ONGs que trabalham directamente com as questões de género. Foram entrevistadas mulheres que ocupam lugares-chave nas instituições governamentais e algumas parlamentares. Foi igualmente consultada a documentação oficial bem como os dados estatísticos que abordam questões ligadas ao género. As observações feitas indicam-nos que a mulher em Moçambique busca gradualmente o seu espaço no desenvolvimento da sociedade, não se esgotando a sua participação apenas nos processos decisórios a nível governamental e das ONGs, antes estendendo-se ao associativismo nos mais diversos campos sociais. A mulher moçambicana participa hoje, individualmente ou organizada em grupo, em lutas e reivindicações colectivas, tendo crescido positivamente ao conseguir ultrapassar diversos obstáculos. A título de conclusão recomenda-se a inclusão de profissionais da área social nos programas de desenvolvimento. Seria uma forma de fortalecer os avanços já alcançados. A presença de assistentes sociais nos órgãos públicos e noutros sectores mais sensíveis, iria por certo permitir reduzir as preocupações dos que buscam estes serviços. ABSTRACT: The present study on the subject: “The Question of Gender in Mozambique: Development and Issues”, demand to understand the importance and contribution that non-governmental organizations provides on the effort of Mozambican woman in having in the society the space that on right belongs to her. The development understood as the economic, social, cultural and political process that aimed a continuous improvement of the population welfare, require the allocation and use of resources for social and economic benefit of society. However in many countries, as is the case of Mozambique, this process is the advancement of certain groups accompanied by the marginalization, exclusion and subordination of others, especially women. Despite improvement in education and combating poverty, access to education for women remains an unusual reality and poverty persists to affect much of Mozambican women, thus causing its social exclusion. On the other hand, although the law recognizes gender equality, women are still oppressed and often the only career that is destined is to be married, take care of the field and having children. However, several exceptions have occurred in which women have to take political positions and functions exclusively reserved to men before. Women's organizations and women leaders participating in favour of the defence of other women have been contributing to its success. UFUPISHO:Maendeleo, yanayosikiwa kama utaratibu wa jamii, ambao unalinga hali njema ya mustarehe wa watu wote wa nchi, yanahitaji toleo na utumizi wa vifaa kwa fadhili ya jamii na ya kiuchumi ya watu jamii. Walakini katika Mozambiki, mwendeleo unaotukia utaratibuni huu hauko sawa. Funzo hili la kuhusu jambo: “ Swali la jinsi ya kuwa kiume au kike Mozambiki: Maendeleo na Tatizo “, lilitafuta kufahamu muhimu na msaada wa wanawake wa Mozambiki katika maeneo mbalimbali ya maendeleo na ongezo la uwezo wao. Funzo lilifanywa juu ya namna nyingi za mapigano na uamuzi kwa kupingana na umaskini na ondoleo katika jamii. Taratibu ya funzo hili ilikuwa uchunguzi jarabati katika onyo la kushirika,ambamo yalifanywa mahojiano, yakitumia maongozi yaliyofanywa mbele ambayo yaliruhusu kujua tabia za elimujamii za “ONGs” ambazo zinafanya kazi juu ya maswali ya jinsi ya kuwa kiume au kike. Walihojiwa wanawake ambao wanamiliki kazi muhimu katika mashirika ya serikali na wanawake wa bunge. Zilichunguwa pia hati rasmi na takwimu zinazohusu maswali ya jinsi ya kuwa kiume au kike. Maonyo yaliyofanywa yanatuonyesha ya kwamba mwanamke katika Mozambika anatafuta kidogo kidogo nafasi yake maendeleoni ya watu jamii, asipojichosha tu kwa kushirika katika taratibu za kubezwa za serikali za “ONGs” na ushirikiano, ukijitanda kwa maeneo ya jamii makubwa zaidi. Mwanamke wa Mozambiki anashirika peke au kwa kundi, akiunganika mapiganoni na madaini ya pamoja, akigua na akiweza kupita vizuizi vingi. Inashauriwa kwamba kama namna ya kuimarisha maendeleo na kwa sababu mwanamke yuko katika sehemu nyingi za jamii, anaingia ndani ya sekta mbalimbali za ufundi kama kwa mfano msaidizi wa jamii. Kuwapo kwa msaidizi wa jamii katika mashirika ya umma na katika sekta nyingine mbalimbali kutaruhusu kumaliza shughuliko ya wale ambao wanatafuta kazi hizi.
