    Alpacas are a species that present physiological, anatomical, morphological and behavioural distinctive characteristics compared to other species used in animal production. Empirical observation of a herd, grazing under time management controlled conditions, allowed to approximate some initial observations about the effect of alpacas in the management of ecosystems. Larger green matter availability in the paddocks grazed by alpacas, evident natural weed control, better plants distribution and increasing stocking capacity were the relevant observed issues. It is considered that the special behavioural characteristics of alpacas in terms of excretion habits, low hoof pressure, food conversion efficiency and grazing habits should be factors to be rigourously studied to explore the value of alpacas as an environmentally friendly species.Sustainable farm management, farming systems research, alpacas, Environmental Economics and Policy, Livestock Production/Industries,

    Farm Management in Australia: The Way Forward

    This paper summarises the outcomes of a National Workshop in Farm Management, 5-6 December 2002, organised by the University of Sydney, Faculty of Rural Management, Orange. At this Workshop leading farmers, industry leaders, corporate representatives, academics, researchers and extension officers explored the future of farm management (education, research and consultancy) in Australia. Major outcomes were that farm management practice is proceeding informally to undertake decisions supporting socially and ecologically friendly, sustainable commercial production agriculture. However the risks of lack of integration, a reductionist approach to only on-farm practice, stagnation of academic programs to respond to leading edge industry initiatives, as well as ill-defined boundaries for farm management research were identified. The analysis indicated that formal educational models, research and extension-consultancy frameworks of an holistic nature, and a multiple bottom line perspective, were appropriate avenues for the future development of farm management practice and research. Workshop participants perceived that a farm management strand emphasising business management rather than technology could be a better educational model. Also there was an emphasis in highlighting the importance of linked development and partnership amongst the different players. The Workshop created the conditions for development of networks among industry, education and consultative research.Farm Management,

    The Australian Farm Business Management Network: Industry, Education, Consultancy and Research Coming Together

    Under the sponsorship of the University of Sydney, on 5-6th December 2002 the future of farm management in Australia was discussed. The fundamental conclusion achieved by key primary industry representatives, corporate executives, academics, consultants and researchers is that farm management will have a more significant role to play in the future than previously in servicing the primary sector. The idea of farm management as a profession was proposed. Its basis would be business management supported by farming systems and technology, and using an holistic approach to action (i.e. finance, people and environment). The new profession of Farm Business Management would seek to influence education, research, consultancy and extension in Australia. Interested parties participating of the 2002 National Farm Management Workshop came away with the idea of championing a consultative network, constituted by interested institutions and interested individuals, as a first step in the process of nurturing the future development of farm business management. By integrating farmers and academics with corporate executives, consultants and researchers the objective is to behave as a consultative group. This group will influence educational models, implement consultancy and research strategies, and network in social and professional terms. Moreover, this network will provide a systematic opportunity for the channelling of farm business management and farming systems related information at different levels for education, extension and scientific purposes. This network is called the Australian Farm Business Management Network (AFBMnetwork).Institutional and Behavioral Economics,

    Consumer perceptions of co-branding alliances: Organizational dissimilarity signals and brand fit

    Get PDF
    This study explores how consumers evaluate co-branding alliances between dissimilar partner firms. Customers are well aware that different firms are behind a co-branded product and observe the partner firms’ characteristics. Drawing on signaling theory, we assert that consumers use organizational characteristics as signals in their assessment of brand fit and for their purchasing decisions. Some organizational signals are beyond the control of the co-branding partners or at least they cannot alter them on short notice. We use a quasi-experimental design and test how co-branding partner dissimilarity affects brand fit perception. The results show that co-branding partner dissimilarity in terms of firm size, industry scope, and country-of-origin image negatively affects brand fit perception. Firm age dissimilarity does not exert significant influence. Because brand fit generally fosters a benevolent consumer attitude towards a co-branding alliance, the findings suggest that high partner dissimilarity may reduce overall co-branding alliance performance

    Breast cancer stem cells: implications for therapy of breast cancer

    Get PDF
    The concept of cancer stem cells responsible for tumour origin, maintenance, and resistance to treatment has gained prominence in the field of breast cancer research. The therapeutic targeting of these cells has the potential to eliminate residual disease and may become an important component of a multimodality treatment. Recent improvements in immunotherapy targeting of tumour-associated antigens have advanced the prospect of targeting breast cancer stem cells, an approach that might lead to more meaningful clinical remissions. Here, we review the role of stem cells in the healthy breast, the role of breast cancer stem cells in disease, and the potential to target these cells

    Cancer Biomarker Discovery: The Entropic Hallmark

    Background: It is a commonly accepted belief that cancer cells modify their transcriptional state during the progression of the disease. We propose that the progression of cancer cells towards malignant phenotypes can be efficiently tracked using high-throughput technologies that follow the gradual changes observed in the gene expression profiles by employing Shannon's mathematical theory of communication. Methods based on Information Theory can then quantify the divergence of cancer cells' transcriptional profiles from those of normally appearing cells of the originating tissues. The relevance of the proposed methods can be evaluated using microarray datasets available in the public domain but the method is in principle applicable to other high-throughput methods. Methodology/Principal Findings: Using melanoma and prostate cancer datasets we illustrate how it is possible to employ Shannon Entropy and the Jensen-Shannon divergence to trace the transcriptional changes progression of the disease. We establish how the variations of these two measures correlate with established biomarkers of cancer progression. The Information Theory measures allow us to identify novel biomarkers for both progressive and relatively more sudden transcriptional changes leading to malignant phenotypes. At the same time, the methodology was able to validate a large number of genes and processes that seem to be implicated in the progression of melanoma and prostate cancer. Conclusions/Significance: We thus present a quantitative guiding rule, a new unifying hallmark of cancer: the cancer cell's transcriptome changes lead to measurable observed transitions of Normalized Shannon Entropy values (as measured by high-throughput technologies). At the same time, tumor cells increment their divergence from the normal tissue profile increasing their disorder via creation of states that we might not directly measure. This unifying hallmark allows, via the the Jensen-Shannon divergence, to identify the arrow of time of the processes from the gene expression profiles, and helps to map the phenotypical and molecular hallmarks of specific cancer subtypes. The deep mathematical basis of the approach allows us to suggest that this principle is, hopefully, of general applicability for other diseases

    Farm Management: rethinking directions?

    No full text
    Farms and farming are major contributors to the world economy, directly responsible for a large part of GDP. These achievements are not trivial and imply that farms are being managed in reasonably effective ways, else agricultural industries would not be sustained. However has the study of Farm Management within Australia made significant contributions to agriculture or lagged in the background. Is it contributing to better Farm Management or merely cataloguing what has happened? Is it leading or following? During recent years there has been an increasing interest in managing farms more sustainably, with emphasis on issues beyond short-term profitability to encompassing rural communities, ecosystems, biodiversity, ethics of technology and politics. The complexity of management has increased, but Farm Management may not be keeping pace with these changes. This paper reviews aspects of Farm Management and how the discipline / field is viewed by different participants. This will be contrasted with related areas of research that have expanded over recent times. It is argued that Farm Management is more a field than an identifiable discipline and questions are raised about where Farm Management is going. Suggestions are made where future studies in farm management could go, the needs for teaching this subject and what are the challenges to be faced in order to enhance the relevance of Farm Management studies for professional farmers

    Farms and farming are major contributors to the world economy, directly responsible for a large part of GDP. These achievements are not trivial and imply that farms are being managed in reasonably effective ways, else agricultural industries would not be sustained. However the study of Farm Management within Australia has been limited over recent decades. Is it contributing to better farm management or merely cataloguing what has happened? Is it leading or following? During that time there has been an increasing interest in managing farms more sustainably, with emphasis in issues beyond short-term profitability to encompassing rural communities, ecosystems, biodiversity, ethics of technology and politics. The complexity of management has increased. This paper reviews aspects of Farm Management and how the discipline / field is viewed by different participants. This will be contrasted with related areas of research that have expanded over recent times. It is argued that Farm Management is more a field than an identifiable discipline and questions are raised about where and why Farm Management is going. Suggestions are made about where future studies in farm management could go, the needs for teaching this subject and what are the challenges to be faced in order to enhance the relevance of farm management studies for professional farmers
