Cursing Kiwis in New Zealand
While still in the midst of their study abroad experiences, students at Linfield College write reflective essays. Their essays address issues of cultural similarity and difference, compare lifestyles, mores, norms, and habits between their host countries and home, and examine changes in perceptions about their host countries and the United States. In this essay, Sarah Sharman describes her observations during her study abroad program at the University of Canterbury in Christchurch, New Zealand
Optimal under voltage load shedding based on stability index by using artificial neural network
Power system is exceptionally sensitive at the generation and consumer side. Inconsistent power requirement under general power production environment may cause power system to approach breakdown or power outages. Load shedding is deliberated as the final choice from the numerous techniques which have been achieved to prevent voltage breakdown. Various studies have been led on this part of the issue. Still, there are possibilities for other ways through optimization of the load shedding. Consequently, the primary reason for this work is to come up with an optimal undervoltage load shedding strategy. Voltage stability is one of the significant worries in functional and preparation of present-day power system. Nevertheless, to obtain the lowest amount to be shed in order to avoid voltage instability, optimization is required. An algorithm was developed to shed the optimal load by considering the load priority whereby the load with least priority will be shed first. The algorithm is working in one step to shed the load. The developed algorithm was tested on IEEE 33-Bus and IEEE 69-Bus radial distribution systems. The results show the equal accuracy of the application of the developed algorithm. In this project, a powerful technique is exhibited for evaluating the optimal amount of load to be shed in a radial distribution system by using artificial neural network. The results of these test cases confirm that 6.57% of bus voltage is increased at the weakest bus in the IEEE 33-Bus system and 10.23% of bus voltage is increased at the weakest bus in the IEEE 69-Bus system. This optimal load shedding algorithm does not over shed or under shed the load. Other achievement includes reduction in load shedding steps. For each test case, the complete load shedding was achieved in 1 step only and the amount of load shed is suitable in each test case respectively. In this project, 29.4% of load is curtailed to stabilize the system which is less compared to other works where about 30% of load is shed to stabilize the system
Constituent Parts: Recent Portraiture in Canadian Military Art
Not common within the art historical record of the Canadian Military, the work of a number of visual artists participating in the Canadian Forces Artists Program demonstrates a keen and growing interest in portraiture. In this article, the work of Gertrude Kearns, Mary Kavanagh, and Erin Riley will be highlighted to illustrate the recent trend. Their work is contrasted with one another as well as with portraiture created by Canadaâs war artists in the First and Second World Wars to bring to light the tensions of representation inherent in military portraiture. It will be shown that shifting perceptions found in the wider employment of portraiture and freedom given to participants in the Canadian Forces most recent official art program have encouraged depictions of members at all levels of the Canadian Forces
Risk Management in the Arctic Offshore: Wicked Problems Require New Paradigms
Recent project-management literature and high-profile disastersâthe financial crisis, the BP
Deepwater Horizon oil spill, and the Fukushima nuclear accidentâillustrate the flaws of
traditional risk models for complex projects. This research examines how various groups with
interests in the Arctic offshore define risks. The findings link the wicked problem framework and
the emerging paradigm of Project Management of the Second Order (PM-2). Wicked problems
are problems that are unstructured, complex, irregular, interactive, adaptive, and novel. The
authors synthesize literature on the topic to offer strategies for navigating wicked problems,
provide new variables to deconstruct traditional risk models, and integrate objective and
subjective schools of risk analysis
Shareholder Employment at Red Dog Mine
Under the Alaska Native Claims Settlement Act of 1971, Iñupiat of northwest Alaska organized as shareholders in the NANA1 Regional Corporation, Inc., and received title to 2,258,836 acres, including rights to the rich Red Dog zinc deposit. In 1982, NANA signed a joint-venture agreement with Teck2 to develop the mine, including provisions for preferential hire for qualified NANA shareholders. The agreement aimed for 100% shareholder hire by 2001. As of 2010, Teck had 220 NANA shareholders in full-time employment, which is 53 percent of the workforce. Other mines around the world have similar indigenous or local hire agreements with mixed success. The Voiseyâs Bay mine sets the high mark for Canada with an Aboriginal hire rate of 54 percent (AETG 2008), followed by Ekati diamond mine at 50 percent (BHP Billiton 2011). So the track record for indigenous employment at Red Dog is high by global standards, although it falls short of NANA and Teckâs goal. What are the continuing barriers to increasing shareholder hire, retention and promotion
Edge-enhanced disruptive camouflage impairs shape discrimination
Disruptive colouration (DC) is a form of camouflage comprised of areas of pigmentation across a targetâs surface that form false edges, which are said to impede detection by disguising the outline of the target. In nature, many species with DC also exhibit edge enhancement (EE); light areas have lighter edges and dark areas have darker edges. EE DC has been shown to undermine not only localisation but also identification of targets, even when they are not hidden (Sharman, Moncrieff, & Lovell, 2018). We use a novel task, where participants judge which âsnakeâ is more âwiggly,â to measure shape discrimination performance for three colourations (uniform, DC, and EE DC) and two backgrounds (leafy and uniform). We show that EE DC impairs shape discrimination even when targets are not hidden in a textured background. We suggest that this mechanism may contribute to misidentification of EE DC targets
From âpreventing accidentsâ to âcreating safetyâ: a maverick approach to the challenges of workplace safety
This Context Statement places central emphasis on my experiential learning and the consequences of my interventions. Through a blend of auto-ethnographical research and reflective practice I analyse, critique and reconceptualise the dominant perceptions and approaches to workplace safety around the world, and the development of my approach to creating the public works which have encouraged, facilitated and supported changes in public perspectives, influenced the evolution of my profession, and developed my personal practice.
Academic research does not always reach the stakeholders that need it most and so I act as a âtranslatorâ to decode the theory to provide practical and meaningful insight to provoke thought, build communities of practice, and galvanise the safety profession with operational leadership. At the core of my works is a new philosophy and model of workplace safety - âCreating Safetyâ - set in sharp contrast to the conventional approaches which tend to be compliance driven and focus on the prevention of accidents. Yet the absence of accidents does not equal the existence of safety. The pursuit of âzero harmâ emanates from poor integration of safety leadership and I argue that a more strategic (and more âmaverickâ or provocative) approach is required.
Cognisant of the need to resonate with the cultural contexts in which I work this Context Statement explores how I consider audience needs, preferences, and language, as I reframe safety as good business leadership, placing exemplary leadership and effective employee engagement at the heart of the approach. Through this hybrid of applied practice and science, Iâm able to reframe what safety means to people, and using a blend of humble inquiry, sensemaking, storytelling and adaptive moves nudge stakeholders towards a mindset shift.
This philosophy has evolved over time, with learning, interaction and experience from a range of disciplines and fields of practice including law, organisational behaviour and positive psychology. It is the golden thread running through my practice, and is shown through critical reflections on my public works in occupational health and safety, including a series of published works (eight books â of which four are included in thus D.Prof analysis and submission - and over 200 professional journal articles regularly reaching more than 80,000 readers), public speaking and teaching, and senior roles within my professional bodies.
This Context Statement supports my own development as a practitioner, further increases the credibility of the âCreating Safetyâ philosophy and contributes to the positive development of workplace safety leadership globally
Using library impact data to inform student marketing campaigns
This article uses an evidenced based approach using the finding of the Library Impact Data Project to help market library resources to students at the University of Huddersfield. Initiatives discussed include the roving librarian, desk-top visits and Lemontree (library game). Reading list software is also used to drive usage and the marketing of these services is also discussed. Finally, the paper looks at the use of a marketing placement student in the library
Recognising and addressing health misinformation in nursing practice
Misleading and inaccurate health information increasingly being shared within the public domain, particularly via social media platforms. This can result in negative real-world consequences, particularly in the context of the coronavirus disease 2019 (COVID-19) pandemic. Nurses and other healthcare professionals need to be aware of those people who are susceptible to believing false information and be prepared to have open conversations with patients about what they may have read or heard about health-related matters. Correcting disinformation and misinformation can be complex as it is often based on part truths and if handled inappropriately can risk causing the belief to become further embedded. This article provides nurses with information and resources to address incorrect information in clinical practice, as well as highlighting strategies for debunking online myths
