Transactions with chance in the garden

This paper discusses change and chance in order to develop a language that can then be used to discuss change in the garden. In the process, it puts forward the idea that to garden is to meddle with the teleonomy of the plants, their “will” to grow as they should. Different design conceptions of change are discussed, particularly the relation of style to design, suggesting that there is the possibility for a material language that both the discourses of gardening and landscape architecture shares that could negotiate this breach. A model or “transactions” between gardener and garden is put forward to begin to get to grips with the particular methods of “working at a remove”, that is, curating conditions rather than designing objects. The paper finally proposes that landscape architecture has to move away from a paranoid engagement with specifiable objects, to one where the designer grooms conditions and sensibilities, and gets out of the office.

Recent developments : loss of chance in medical litigation : Tabet v Gett [2010] HCA 12.

Following the judgement of the High Court in Tabet v Gett [2010]HCA 12 handed down on 21 April 2010 it appears that in Australia there is now very limited scope for recovery in negligence for the loss of a chance of a better medical outcome.

Loss of chance in medical negligence claims now a lost cause?

The question whether the loss of chance of a better medical outcome in cases of medical negligence should be recognised as actionable damage is ‘a question which has divided courts and commentators throughout the common law world.’ In April 2010, the High Court handed down its anticipated decision in the case of Tabet (by her Tutor Sheiban) v Gett (2010) 240 CLR 537. The issue considered by the court was whether the appellant could claim in negligence for the loss of a chance of a better medical outcome. This issue had not been considered by the High Court previously, the most relevant cases being Rufo v Hosking (2004) 61 NSWLR 678 and Gavalas v Singh (2001) 3 VLR 404. Claiming for a loss of chance in a personal injury action raises questions as to recognised damage and causation, and the members of the High Court considered both of these.

A chance for diversity? Australian online journalism

Australia’s mainstream media landscape has long been recognised as highly limited – media ownership in the country has traditionally been concentrated in the hands of a very few, and (except for Sydney and Melbourne) it is common for major Australian cities to be served by only one local newspaper, usually produced by Rupert Murdoch’s News Ltd. This can be seen also to affect the quality and diversity of Australian journalism; additionally, the global decline of newspaper publishers’ revenues and overall adverse economic conditions exert further pressure on journalistic operations in the country. At the same time, and possibly in response to the increasing stresses on industrial journalism in the country and the implications they have for the quality of journalistic products, a vibrant and dynamic ecosystem of Australian industrial and citizen journalism publications has emerged online. Existing media organisations have built strong news brands online, while citizen journalists and political bloggers have given voice to issues, concerns, and opinions hitherto underrepresented in Australian mainstream journalism; of particular interest, however, is the increasing level of engagement and interaction between the two. While such interaction has been characterised by deep animosity at times (especially also in the context of the Australian federal election in November 2007), Australia has also seen the emergence and establishment of a number of new, intermediary online publications which act as spaces for public debate and analysis – from the public intellectualism of Online Opinion through the muckraking of Crikey to the progressive politics of New Matilda. The rise of social media as spaces for the discussion of news and politics further changes the media environment, potentially leading both to renewed conflict between professional and citizen journalists and to a greater level of engagement between journalists and audiences. Overall, then, such online developments offer a chance for a greater diversity of opinion and representation in Australian journalism, but also remain under a cloud from uncertain long-term business models and funding arrangements. This chapter outlines current trends in Australian online journalism, and speculates about their effect on the Australian news media landscape.

The second chance project: A multi-level examination of secondary prevention practices for Saudi people following a recent cardiac event

The study examined the health-related behaviours of Saudi people following a recent cardiac event and identified the factors that influence these behaviours using McLeroy et al.'s (1988) Ecological Model of Health Behaviours as a guiding framework. The study was one of the first in Saudi Arabia to examine the health-related behaviours of Saudi people following a recent cardiac event. The study findings emphasise the importance of a program that integrates secondary prevention practices, educational approaches and targeted supportive services in cardiac care in Saudi Arabia.

Reservoir Operation for Hydropower Optimization: A Chance-Constrained Approach

This paper presents a chance-constrained linear programming formulation for reservoir operation of a multipurpose reservoir. The release policy is defined by a chance constraint that the probability of irrigation release in any period equalling or exceeding the irrigation demand is at least equal to a specified value P (called reliability level). The model determines the maximum annual hydropower produced while meeting the irrigation demand at a specified reliability level. The model considers variation in reservoir water level elevation and also the operating range within which the turbine operates. A linear approximation for nonlinear power production function is assumed and the solution obtained within a specified tolerance limit. The inflow into the reservoir is considered random. The chance constraint is converted into its deterministic equivalent using a linear decision rule and inflow probability distribution. The model application is demonstrated through a case study.

Sri Lankan entrepreneurs in Australia: Chance or choice?

Purpose Ethnic entrepreneurship is, and always has been, a means of survival. However, there is limited literature on ethnic entrepreneurship in Australia and therefore, an understanding of ethnic entrepreneurs’ motivations to become self-employed. The purpose of this paper is to report the influential factors in the decision to engage in self-employment through case studies of members of Melbourne’s Sri Lankan community informed by the mixed embeddedness approach. Design/methodology/approach The mixed embeddedness approach frames the study where the authors examine the motivations for business of five Sri Lankan entrepreneurs. Narratives are used to construct individual case studies, which are then analyzed in terms of the motivations for, resources used and challenges faced on the entrepreneurial journey. Findings For these ethnic entrepreneurs, their entrepreneurial activity results from a dynamic match between local market opportunities and the specific ethnic resources available to them at the time of founding. The self-employment decision was not prompted by a lack of human capital but an inability to use that human capital in alternative means of employment at specific points in time. Moreover the authors highlight the importance of social and cultural capital as resources used to overcome challenges on the entrepreneurial journey. Originality/value In this community, entrepreneurship was not a result of a lack of human capital but how it was utilized in combination with social and cultural capitals in the given opportunity structure. The mixed embeddedness approach enables the uncovering of how ethnic network ties were used in light of the opportunities available to build entrepreneurial activity.

Interval Data Classification under Partial Information: A Chance-Constraint Approach

This paper presents a Chance-constraint Programming approach for constructing maximum-margin classifiers which are robust to interval-valued uncertainty in training examples. The methodology ensures that uncertain examples are classified correctly with high probability by employing chance-constraints. The main contribution of the paper is to pose the resultant optimization problem as a Second Order Cone Program by using large deviation inequalities, due to Bernstein. Apart from support and mean of the uncertain examples these Bernstein based relaxations make no further assumptions on the underlying uncertainty. Classifiers built using the proposed approach are less conservative, yield higher margins and hence are expected to generalize better than existing methods. Experimental results on synthetic and real-world datasets show that the proposed classifiers are better equipped to handle interval-valued uncertainty than state-of-the-art.

Chance constrained uncertain classification via robust optimization

This paper studies the problem of constructing robust classifiers when the training is plagued with uncertainty. The problem is posed as a Chance-Constrained Program (CCP) which ensures that the uncertain data points are classified correctly with high probability. Unfortunately such a CCP turns out to be intractable. The key novelty is in employing Bernstein bounding schemes to relax the CCP as a convex second order cone program whose solution is guaranteed to satisfy the probabilistic constraint. Prior to this work, only the Chebyshev based relaxations were exploited in learning algorithms. Bernstein bounds employ richer partial information and hence can be far less conservative than Chebyshev bounds. Due to this efficient modeling of uncertainty, the resulting classifiers achieve higher classification margins and hence better generalization. Methodologies for classifying uncertain test data points and error measures for evaluating classifiers robust to uncertain data are discussed. Experimental results on synthetic and real-world datasets show that the proposed classifiers are better equipped to handle data uncertainty and outperform state-of-the-art in many cases.

Eine Chance fur eine positive Bestandsentwicklung in der Ostsee? Hoffnungswoller Dorschjahrgang in der Ostee bestagtigt

Neue Chance für den Nordsee-Kabeljau

Während der 483. Reise von FFK “Solea“ (24.10. bis 9.11.01) wurde wie in jedem Herbst die Nachwuchssituation von Kabeljau in der Deutschen Bucht untersucht. Der dabei berechnete Index hat sich in seiner 20-jährigen Laufzeit als relativ verlässliches Maß für die Abschätzung der Stärke des jeweils jüngsten Jahrgangs erwiesen.

Neue Chance für den Nordsee-Kabeljau: Seevögel machen bereits im Sommer 2001 auf starken Jahrgang aufmerksam

Im Oktober/November des vergangenen Jahres ergab sich während der 483. Reise von FK „Solea“ ein im Vergleich zu den vier Vorjahren hoher Fangindex von 220 Kabeljau Gadus morhua je Stunde (Weber 2001). Die Fische hatten eine Länge von 15 bis18 cm und waren besonders in Küstennähe Ostfrieslands anzutreffen. Durch unsere Langzeituntersuchungen zur Ökologie der Flussseeschwalbe Sterna hirundo im Wattenmeer sind wir bereits im Juni des Jahres 2001 auf den starken Jahrgang des Kabeljaus aufmerksam geworden und können die Vermutung von Weber bestätigen, dass die Kabeljaus den Sommer über im Wattengebiet herangewachsen sind.

Fangmengenbegrenzungen in der Garnelenfischerei - eine Chance fur weitere Biefangreduzierungen

Aiming for price stabilisation Danish, German and Dutch brown shrimp fisheries agreed on weekly catch limitations for the years 1998 and 1999. This resulted in fishing effort reduction of 18 % of the total number of fishing trips in 1998 and up to 24 % in summer. In that period highest abundance of young plaice occurs in the Wadden Sea which is the fishing area of the brown shrimp fleets of Germany and the Netherlands. Consequently as a side effect a reduction of the total annual by-catch especially of young plaice must have occurred. According to formerly conducted EU-studies and investigations the by-catch reduction due to the agreed catch limitations should have led to survival of millions of young plaice. They give a potential of some extra catch in coming years which is 2,5 % of the total TAC of plaice in the North Sea. Compared to the German TAC in year 2000 the gain equals 44 %. The catch limitations effect on by-catch reduction in 1998 was in the same order of magnitude of the one achievable by technical measures in net selection applied in that fishery and research. A combination of both could substantially reduce traditional by-catch levels in brown shrimp fisheries.Aiming for price stabilisation Danish, German and Dutch brown shrimp fisheries agreed on weekly catch limitations for the years 1998 and 1999.
