Civic geographies of architectural enthusiasm

In this short intervention, we introduce the display and walking tour that formed our contribution to the ‘civic geographies’ exhibition and session at the Royal Geographical Society (with IBG) Annual Conference in July 2012. We then move on to explore the notion of ‘civic geographies’ in relation to the architectural enthusiasm, specifically a strong emotional attachment to buildings, exhibited by members of The Twentieth Century Society. In doing so, we suggest that a more critical account of the role of enthusiasm in the civic realm is required for two important reasons: first, because such groups can be understood to be doing geography beyond the academy in the civic realm; and second, because enthusiast knowledges and practices are active in the (re)constitution of civic landscapes of various kinds. Enthusiasts participate in caring for buildings, preserving heritage, making community spaces, as well as creating and curating local histories. An understanding of who is participating in making these civic geographies, why, how, and with what consequences, is therefore crucial.

Mobile sink based fault diagnosis scheme for wireless sensor networks

Network diagnosis in Wireless Sensor Networks (WSNs) is a difficult task due to their improvisational nature, invisibility of internal running status, and particularly since the network structure can frequently change due to link failure. To solve this problem, we propose a Mobile Sink (MS) based distributed fault diagnosis algorithm for WSNs. An MS, or mobile fault detector is usually a mobile robot or vehicle equipped with a wireless transceiver that performs the task of a mobile base station while also diagnosing the hardware and software status of deployed network sensors. Our MS mobile fault detector moves through the network area polling each static sensor node to diagnose the hardware and software status of nearby sensor nodes using only single hop communication. Therefore, the fault detection accuracy and functionality of the network is significantly increased. In order to maintain an excellent Quality of Service (QoS), we employ an optimal fault diagnosis tour planning algorithm. In addition to saving energy and time, the tour planning algorithm excludes faulty sensor nodes from the next diagnosis tour. We demonstrate the effectiveness of the proposed algorithms through simulation and real life experimental results.

The characterisation of the protective film formed by benzotriazole on the 90/10 copper-nickel alloy surface in H2SO4 media

The nature of the protective film formed by benzotriazole (BTAH) on the surface of the 90/10 CuNi alloy in deaerated 0.5 mol L-1 H2SO4 solution containing Fe(III) ions as oxidant was investigated by weight-loss, calorimetric measurements, and by surface-enhanced Raman spectroscopy (SERS). The SERS measurements show that the protective film is composed by the [Cu(I)BTA](n), polymeric complex and that the BTAH molecules are also adsorbed on the electrode surface. A modification of the BET isotherm for adsorption of gases ill solids is proposed to describe the experimental results obtained from weight-loss experiments that suggest an adsorption in multilayers. Electrochemical studies of copper and nickel in 0.5 mol L-1 H2SO4 in presence and absence of BTAH have also been made as an aid to interpret the results. The calculated adsorption free energy of the cuprous benzotriazolate on the surface of the alloy is in accordance with the value for pure copper. (C) 2007 Elsevier Ltd. All rights reserved.

Experiencing Science in Action: The Use of Exhibition Techniques in Guided Tours to a Scientific Laboratory

The current paper presents a study conducted at CERN, Switzerland, to investigate visitors' and tour guides' use and appreciation of existing panels at visit itinerary points. The results were used to develop a set of recommendations for constructing optimal panels to assist the guides' explanation.

Use Multilevel Graph Partitioning Scheme to solve traveling salesman problem

The traveling salesman problem is although looking very simple problem but it is an important combinatorial problem. In this thesis I have tried to find the shortest distance tour in which each city is visited exactly one time and return to the starting city. I have tried to solve traveling salesman problem using multilevel graph partitioning approach.Although traveling salesman problem itself very difficult as this problem is belong to the NP-Complete problems but I have tried my best to solve this problem using multilevel graph partitioning it also belong to the NP-Complete problems. I have solved this thesis by using the k-mean partitioning algorithm which divides the problem into multiple partitions and solving each partition separately and its solution is used to improve the overall tour by applying Lin Kernighan algorithm on it. Through all this I got optimal solution which proofs that solving traveling salesman problem through graph partition scheme is good for this NP-Problem and through this we can solved this intractable problem within few minutes.Keywords: Graph Partitioning Scheme, Traveling Salesman Problem.

This was made possihle hy an exchange researcher grant from the Royal Swedish Academy of Engineering Sciences.

Arctic Tourism: Realities & Possibilities

This paper addresses human capital in the Arctic in relation to tourism. More specifically, with an ever-increasing number oftourists recognizing the attractiveness of the Arctic, tour companies are increasingly recognizing the opportunities. The media(typically southern media) sells the image, either before or after the tourists arrive, and communities are often left to deal with therepercussions – whether those are social, economic, environmental, or the like. Many of the repercussions are negative; however,even when perceived as positive they can create tensions within small communities and showcase a variety of capacity issues.This paper focuses on the realities and possibilities of tourism in the Arctic. It offers an up-to-date descriptive overview of tourismnumbers and valuations. In addition, ‘realities’ also focuses on the current suite of challenges and ‘possibilities’ addresses criticalquestions that need to be asked as tourism grows. We are in an uncertain age and academic critique of the Arctic tourismphenomenon is growing as quickly as the numbers. This paper is almost fully circumpolar in outlook, written by individuals fromthose jurisdictions, and aims to intersect with other sectors active in the Arctic.

A Quinta Essência de Agustina Bessa-Luís : la saveur aigre-douce de Macao

In the narrative A Quinta Essência Agustina Bessa-Luís proposes an original reading of the Portuguese postcolonial History, by reinvesting the topics of the intercultural relation and the meeting with the Other. In fact, in the troubled context of April 1974, the character of Jose Carlos Pessanha expatriates towards the East, more precisely towards Macao, one of the last Eastern colonies of the Portuguese colonial Empire. However, the characteristic of this tour of rediscovery of the East is that it makes the destiny of a character in search of himself coincide with the questioning of a country still looking for its own identity. Thus, in this voyage backwards into the Luso-Eastern History, the Author draws the portrait of a Nation-Empire split between the desire of incarnating this “genetic superiority of the Occident” and the fascination for the culture of the Other, symbolizing an “excess of otherness” (B. of Sousa Santos) in the Portuguese identity. Macao, will be the territory of an “entre-deux” and an intercultural circulation, as well as an emblematic ground to the expression of the “ambivalent and hybrid” position (colonizing/colonized) of Portugal in the Occident. As a consequence, the uncomfortable “non-inscription” (J. Gil) and the “nomadism” (Deleuze/Guattari) which characterizes José Carlos Pessanha, would be a reflection of yesterday’s and today’s Lusitanian epopee.

Guides of the Falu Mine : Perceptions of Differences and Similarities onDomestic and International Visitors

Industrial heritage tourism has been in focus for many academic studies and tourism is an alternative developmental tool for mines and contributes to their economic success. This thesis is about the Falu Mine in Dalarna, Sweden, which has World Heritage status since 2001 and is one of the biggest attractions in the region. Its history and cultural importance are reasons for the importance of preserving the heritage. The Falu Mine is under the management of the Great Copper Mountain Trust and one of their ambitions is to ensure the continuous popularity among domestic and international visitors. In order to gain a better understanding of the visitors and to find strategies to improve performance, a visitor survey has been conducted in the summer of 2011. It is the authors believe that the guides of the Falu Mine have the best available insight and that their perceptions help to add to the understanding about the visitors. Therefore, this thesis aims to explore the perceptions of the guides about their visitors, to investigate how the perceptions correspond to the statistical results and to study if there are any differences between domestic and international visitors. The mixed methods approach will increase the depth and accuracy of the results, by linking qualitative with quantitative data. The results show that differences between domestic and international visitors exist, both proven by interviews with the guides and the visitor survey. These differences occur in the factors, such as level of education of the visitors, group size and number of children in the group, knowledge of the visitors prior to and after the visit, sources of information and the fulfillment of the visitor expectations. The perceptions emphasize how these differences impact the guided tours. The guides of the Falu Mine have to be aware of those differences in order to adjust the tour accordingly, as well as the management of the Falu Mine can use this knowledge in order to identify strategies for improving performance.

Popular culture/sacredness

A huge billboard faces me as I crawl down Punt Road Melbourne, its wild purple and yellow-daubed sports fan (male) leering over the northbound traffic. Its message: 'Sport is a Religion, so pray for Yamaha Stadium Sound'  Canny advertising, hooking into aussie culture, selecting an aussie take on religion/ sport (fun, serious, primitive, fanatic, central). Next, there's the Next fashion ad, with its larger than life-sized photograph of a gorgeously dressed young female eying off the pope's long white robe, comparing outfits. Fashion as religion, or better than, really, is the inference-she looks mildly
amused, and he looks a little nonplussed. And then there are the many Qantas advertisments for 'Spirit of. Australia' featuring Aboriginal figures, with backdrops of Dlum and the red desert. As cultural tour businesses know, there's money to be made in taking urban, nonIndigenous tourists to visit their 'spiritual other', the Aboriginal.1 Or there's the multicultural, children's version of the ad, with all the little global travellers of the future featured in wonderful locations. Spirit of Australia.

Globalisation and manufacturing strategy in the TCF industry

Purpose – The textiles, clothing, and footwear (TCF) industry has struggled in Australia since the government commenced dismantling tariffs. By sourcing from Asia, middlemen undercut established suppliers, and retail chains set benchmark low prices with their imported “house” labels. The policy-makers predicted that local producers would become more efficient, and export to make up for lost sales, but the media paints a picture of rising imports, retrenchments, and factory closures. The research objective was to discover what strategies the survivors (actually) employ in adapting to the pressures of globalisation.

Design/methodology/approach – More than 30 companies were involved in the study, ranging from small family businesses to subsidiaries of big multinationals. Each case study was based on an interview with a senior executive, normally followed by a plant tour. This methodology suits a fresh topic, as it avoids preconceptions and imposes no bounds.

Findings – Results show that the policy change was based on “pie in the sky” forecasts. Increasingly, TCF production is transferred to cheap offshore locations, generally via subcontracting plus the “badging” of foreign designs. To survive, local factories should focus on quality and customer service, preferably in niche markets (like uniforms), or for specific customer groups, and develop technologically advanced products. A move down the supply chain into retailing can also assist. Large multinational corporations that engage in foreign direct investment dominate the management literature.

Originality/value – This paper presents a different perspective, neglected in international operations management, whereby domestically oriented businesses attempt to defend themselves against the adverse consequences of globalisation.

It's not only rock and roll: rockumentary, direct cinema and performative display

The documentary form commonly referred to as rockumentary has become, since its inception in the early 1960s, a staple of American direct cinema. In keeping with its associations with observational direct cinema, rockumentary emphasizes showing over telling; that is, rockumentary privileges the visual capacities of documentary over patterns of exposition. While the ‘documentary display’ of rockumentary is comparable to certain features of  the early ‘cinema of attractions’ it exceeds such features in its focus on  performance. Typically, an emphasis within documentary theory on unmediated and unreconstructed access to the real as the basis of documentary film has not admitted a place for notions of performance before the camera. Rockumentary, with its relentless foregrounding of the performing body and the performance of musicians, revises this  understanding. This essay examines rockumentary within the context of direct cinema as a mode centred on a documentary performative display as it operates within selected works from the 1960s to the present. The film theorist Brian Winston has claimed that ‘[d]irect cinema made the rock performance/tour movie into the most popular and commercially viable documentary form thus far.’ The inverse of this assessment may be closer to the mark: the rockumentary turned direct cinema into a commercially and widely available form, one which the rockumentary has at times returned to and superseded in its scopic attention to performative display.

Facets of the polytope of the asymmetric travelling salesman problem with replenishment arcs

The Asymmetric Travelling Salesman Problem with Replenishment Arcs (RATSP) is a new class of problems arising from work related to aircraft routing. Given a digraph with cost on the arcs, a solution of the RATSP, like that of the Asymmetric Travelling Salesman Problem, induces a directed tour in the graph which minimises total cost. However the tour must satisfy additional constraints: the arc set is partitioned into replenishment arcs and ordinary arcs, each node has a non-negative weight associated with it, and the tour cannot accumulate more than some weight limit before a replenishment arc must be used. To enforce this requirement, constraints are needed. We refer to these as replenishment constraints.

In this paper, we review previous polyhedral results for the RATSP and related problems, then prove that two classes of constraints developed in V. Mak and N. Boland [Polyhedral results and exact algorithms for the asymmetric travelling salesman problem with replenishment arcs, Technical Report TR M05/03, School of Information Technology, Deakin University, 2005] are, under appropriate conditions, facet-defining for the RATS polytope.

New cutting-planes for the time-and/or precedence-constrained ATSP and directed VRP

In this paper, we introduce five classes of new valid cutting planes for the precedence-constrained (PC) and/or time-window-constrained (TW) Asymmetric Travelling Salesman Problems (ATSPs) and directed Vehicle Routing Problems (VRPs). We show that all five classes of new inequalities are facet-defining for the directed VRP-TW, under reasonable conditions and the assumption that vehicles are identical. Similar proofs can be developed for the VRP-PC. As ATSP-TW and PC-ATSP can be formulated as directed identical-vehicle VRP-TW and PC-VRP, respectively, this provides a link to study the polyhedral combinatorics for the ATSP-TW and PC-ATSP. The first four classes of these new cutting planes are cycle-breaking inequalities that are lifted from the well-known D^-_k and D⁺_k inequalities (see Grötschel and Padberg in Polyhedral theory. The traveling salesman problem: a guided tour of combinatorial optimization, Wiley, New York, 1985). The last class of new cutting planes, the TW ₂ inequalities, are infeasible-path elimination inequalities. Separation of these constraints will also be discussed. We also present prelimanry numerical results to demonstrate the strengh of these new cutting planes.

Rugby league: a game in crisis

This study examines the issue of crisis and reputation management strategies in Australian sporting clubs and finds that not only are individual clubs unaware of the potential impact of such crises on their organizations, but that they also have no training, contingency plans, or strategies to handle crises of any sort either at this or at the national league level. It uses the Australian Rugby League organization as a case study f()r examining these issues and concludes with several recommendations for improving crisis management and communications policies in Australian sporting organizations and for their stakeholders.

Many public and private organizations prefer to ignore the reality that "bad things" can happen, either through denial of their vulnerabilities or through myopia about their successes and strengths (Elliott, 2002). A crisis can be defined as any problem or disruption that triggers negative stakeholder reaction and extensive public scrutiny (Newman, 2003). Effective crisis management lies in continuous learning processes designed to equip managers with the capabilities, flexibility, and confidence to deal with sudden and unexpected problems or events (Robert & Lajtha, 2002). Good crisis leaders are those who can make fast decisions under pressure and who can keep the big picture consequences of actions and words in mind when making these decisions 030in & Lagadec, 20(0). In 2004, the Rugby league in Australia was both ill-prepared and ill-advised to effectively deal with a sex scandal involving a number of their players on an official club tour. In classic crisis escalation, what should have been a serious but easily dealt with problem became a major reputational and institutional crisis for the league, its sponsors, its players, and its fans.
