Resilience viewed through the lens of climate change and water management

Resilience is not a new idea but there has been an upsurge in efforts to operationalize the concept within water management. This review begins with a synopsis of related themes around persistent and emerging pressures on freshwaters; environmental thresholds (or tipping points); ‘safe’ operating conditions; multiple stable states; regime shifts. A case is made for viewing and managing the resilience of water systems at nested scales. Indicators are needed to track evolving climate risks as well as to measure socio-ecological responses. Catchment properties can identify those river systems that are more or less likely to return to a pre-disturbance state; resilience further depends on institutional and social landscapes. Ideally, allied notions of resistance and reliability are applied alongside resilience to broaden the portfolio of adaptation measures. Water managers would also benefit from more consistent use of resilience terminology; incentives to build back better after catastrophes; strategic monitoring of incipient threats and tipping points; availability of long-term adaptation indicators; coordinated efforts to reduce non-climatic pressures on freshwaters (especially in headwaters); evidence-based, practical guidance on adaptation measures that build resilience

Good Composure: Mapping Shifting Norms in the Language of Televised Australian Rules Commentary

This thesis has its origins deeply rooted in astonishment and curiosity. When I sat to watch a televised game of Australian Rules football in 2009, after a viewing absence of over two decades, I found that the language was so distinctly foreign, the positioning of the ordinary so unexpected that it took a while to locate. The contrast between my expectations, however deeply buried they may have been, and the actuality seemed a seismic shift in the ideology of what (in my raised-in-Melbourne-mind) is not only Australia’s national sport, but also the greatest contest game on earth. Degrees of ambivalence were communicated through the commentary that were unfamiliar to me and I was curious to see how language in broadcast football commentary had transitioned from that I imagined I remembered to that now being heard over an interval of more than 20 years. As it turned out my investigations into broadcast commentary begin in the same decade I have actual, if debatably accurate, memory of (the 1970s). Therefore, it is as much against my own life experiences and understandings that these changes in the words we use in our ordinary lives have been mapped, as it is of the scholarly theorists whose work has guided my prodding, most particularly Walter Benjamin and James Clifford. We are each shaped by our environment and this is reflected nowhere more accurately than in the words we choose to use. It appears likely language is instrumental in facilitating transition between one accepted ordinary and another, states of ordinary which are today rapidly superseded by newer ordinaries in part because of the ability to communicate with unprecedented range and reach. In the early days of television, particularly in Melbourne, football was a social knit-stitch that pulled far-flung communities closer. Fifty years ago there was more than mere distance between industrial Geelong and bayside Moorabbin or inner-city Fitzroy but football, very present in the everyday, wove connecting threads where there were few other commonalities, for man, woman and child alike. Establishing club allegiance was an early question in any new friendship or random introduction. The people who watch are as important to the longevity of the game as the players are. The few people who describe the game to the many people who watch – both those that attend games physically, and those removed watching broadcasts – are immersed in a world that their audience enters and leaves at will. Increasingly these commentators are ex-players, even further submerged in the game, its politics and its ethos. Although football has been played by men chasing an erratically bouncing oval ball for more than one hundred years, the language with which it is communicated has changed through the decades. What the commentators of today are choosing to say to those watching is different because when they look at men chasing an erratically bouncing oval ball, they are no longer seeing the same things their predecessors did. Tracking how language reflects the changing of that which is seen has been made possible by a process of immersion in the world of football. I have watched 325 full games of football (listed in Appendix 2), several of them more than once, purely for the exercise of listening to the commentary. The final quarters of 69 games have been transcribed in full; the travails of converting audio to text, and the selection processes are outlined in the Methodology chapter, page 20. Without including reading or research, simply listening and transcribing has exceeded the equivalent of 25 forty-hour work weeks (1000 hours). Aware few are afforded such opportunity to indulge a curiosity it must be acknowledged that listening with intent is a habit, once acquired, difficult to discard. Submersion in the idiosyncrasies of any narrowly defined culture must alter one’s world view. This, therefore, is an in-depth look at how that which is accepted as ordinary within the language of televised Australian Rules football commentary has changed between the 1970s and the 2010s. This work was formally begun in 2015, a time which within the writing of this has already become the past and will be forming an interpretable aura of its own. Within the industry of football as a marketable product on a media system as competitive as the code itself, is a language, a form of communication that has moved through time in tandem with the game. This is history. The changes in the ways in which Australians wield language in the world of Australian Rules football, a competitive contact sport with such broad and varied reach, reflects altered perspectives over half a century. What follows is the story told by a collection of transcripts from five decades of televised football

Modeling the Interdependences between Voltage Fluctuation and BTI Aging

With technology scaling, the susceptibility of circuits to different reliability degradations is steadily increasing. Aging in transistors due to bias temperature instability (BTI) and voltage fluctuation in the power delivery network of circuits due to IR-drops are the most prominent. In this paper, we are reporting for the first time that there are interdependences between voltage fluctuation and BTI aging that are nonnegligible. Modeling and investigating the joint impact of voltage fluctuation and BTI aging on the delay of circuits, while remaining compatible with the existing standard design flow, is indispensable in order to answer the vital question, “what is an efficient (i.e., small, yet sufficient) timing guardband to sustain the reliability of circuit for the projected lifetime?” This is, concisely, the key goal of this paper. Achieving that would not be possible without employing a physics-based BTI model that precisely describes the underlying generation and recovery mechanisms of defects under arbitrary stress waveforms. For this purpose, our model is validated against varied semiconductor measurements covering a wide range of voltage, temperature, frequency, and duty cycle conditions. To bring reliability awareness to existing EDA tool flows, we create standard cell libraries that contain the delay information of cells under the joint impact of aging and IR-drop. Our libraries can be directly deployed within the standard design flow because they are compatible with existing commercial tools (e.g., Synopsys and Cadence). Hence, designers can leverage the mature algorithms of these tools to accurately estimate the required timing guardbands for any circuit despite its complexity. Our investigation demonstrates that considering aging and IR-drop effects independently, as done in the state of the art, leads to employing insufficient and thus unreliable guardbands because of the nonnegligible (on average 15% and up to 25%) underestimations. Importantly, considering interdependences between aging and IR-drop does not only allow correct guardband estimations, but it also results in employing more efficient guardbands

A Model Parent Involvement Program

It is vital that educators provide opportunities for parents to become partners in the education of their children. With an increased emphasis on parent involvement, educators are seeking new ways to involve families in their children\u27s education. Parent involvement can and should take a variety of forms. The purpose of this project was to design and develop a program for elementary schools that details how a parent involvement model of Family Fun Nights could help provide parents with a better understanding and knowledge of the Washington State Essential Academic Learning Requirements. The format also allows an opportunity for parents to be actively involved in a supportive and non-threatening environment

Aircraft-sized anechoic chambers for electronic warfare, radar and other electromagnetic engineering evaluation

This paper considers capabilities and benefits of aircraft-sized radio/radar frequency anechoic chambers for Test and Evaluation (T&E) of Electronic Warfare (EW), radar and other electromagnetics aspects of air and ground platforms. There are few such chambers worldwide. Initially developed to reduce costs, timescales and risks associated with open-air range flight testing of EW systems, their utility has expanded to most areas of platforms’ electromagnetics’ T&E. A key feature is the ability to conduct T&E of nationally sensitive equipment and systems, fully installed on platforms, in absolute privacy. Chambers’ capabilities and uses are described, with emphasis on key infrastructure and instrumentation. Non-EW uses are identified and selected topics elaborated. Operation and maintenance are discussed, based on experiential knowledge from international use and the authors’ 30 years’ involvement with BAE Systems’ EW Test Facility. A view is provided of trends and challenges whose resolution could further increase chamber utility. National affordability challenges also suggest utility expansion to support continuing moves, from expensive and difficult to repeat flight test and operational evaluation trials, towards an affordability-driven optimal balance between modelling and simulation, and real-world testing of platforms
