Viviamo in un epoca di cambiamenti. Continuamente, giorno dopo giorno, il vecchio scompare per fare spazio al nuovo. La tecnologia permea sempre più in ogni aspetto della vita, conquistando le nostre abitudini, cambiando il nostro modo di vedere il mondo, e, in maniera inevitabile, il nostro modo di agire. L’essere umano ha da sempre cercato di concepire cose che ancora non ci sono, per cambiare la realtà e modellarla a suo piacimento. Si parte, quindi, da qualcosa che fin dalla nascita è dentro ognuno di noi, un desiderio che arde nell'animo umano, che si alimenta grazie al soffio dell’immaginazione e che non c’è modo di spegnere. L’innovazione porta novità. Resistere al cambiamento non è sempre facile, e se si cerca di ostacolarlo esso ti travolgerà. “Affrontare il cambiamento è come scalare una colata di fango giù per una collina” - esordisce in “The Innovator Dilemma”, Clayton M. Christensen - “Bisogna affrontare qualsiasi cosa per rimanere su di essa, e non appena ci si ferma per prendere fiato si viene seppelliti”. Si intuisce come il cambiamento tecnologico non solo sia di fondamentale evidenza nella vita di ognuno, ma come esso abbia cambiato e stia cambiando il modo di fare business. In questo umile lavoro si è voluto analizzare come certi tipi di innovazione abbiano il potere di cambiare tutto un sistema di riferimento sul quale prima l’impresa faceva affidamento. Sono le Disruptive Innovation – le innovazioni dirompenti – quelle innovazioni che ribaltano un modello di business, il modo di vedere un prodotto, la logica dietro a certe operations aziendali, che seppur sembrassero solide, si sgretolano scontrandosi con innovazioni così forti. Vi è poi una domanda critica a cui si è cercato di rispondere. Si può fare Disruptive Marketing? Alcuni esempi virtuosi ci mostrano come si possa attuare una strategia di questo genere, e come si possa “comprendere, creare, comunicare e distribuire valore” in modo innovativo.

In questa tesi si vuole fornire una panoramica generale dei processi di formazione delle galassie, con l'aggiunta di alcuni cenni sulla loro evoluzione. Nel primo capitolo si danno alcune informazioni sulla natura di questi oggetti e su come è stata scoperta la loro esistenza. Poi, utilizzando le premesse di cui al capitolo 2, nel capitolo 3 si passa alla spiegazione della loro formazione a partire dagli eventi successivi al Big Bang, di cui si fornisce una breve cronologia. Nel capitolo 4 si dà una panoramica della formazione degli ammassi di galassie e si discute di alcune osservazioni compiute su di essi, per concludere con considerazioni sul loro futuro. Infine, nell'ultimo capitolo ci si concentra sull'evoluzione delle galassie, in particolare sui processi di merging e sulle collisioni.

The advantages of bundling e-journals together into publisher collections include increased access to information for the subscribing institution’s clients, purchasing cost-effectiveness and streamlined workflows. Whilst cataloguing a consortial e-journal collection has its advantages, there are also various pitfalls and the author outlines efforts by the CAUL (Council of Australian University Libraries) Consortium libraries to further streamline this process, working in conjunction with major publishers. Despite the advantages that publisher collections provide, pressures to unbundle existing packages continue to build, fuelled by an ever-increasing selection of available electronic resources; decreases in, and competing demands upon, library budgets; the impact of currency fluctuations; and poor usage for an alarmingly high proportion of collection titles. Consortial perspectives on bundling and unbundling titles are discussed, including options for managing the addition of new titles to the bundle and why customising consortial collections currently does not work. Unbundling analyses carried out at Queensland University of Technology during 2006 to 2008 prior to the renewal of several major publisher collections are presented as further case studies which illustrate why the “big deal” continues to persist.

Our survey findings confirm that 11 factors influence information and communication technology (ICT) diffusion for experienced ICT users. We offer a model that consists of 4 groups of categories: management (M); individual (I); technology (T); and environment (E). Our conclusions reinforce the importance of a coherent ICT diffusion strategy and supportive environment. This requires substantial investment in training and collegial learning support mechanisms. This paper provides an overview of the work undertaken and an analysis of its implications for the construction industry and we provide useful insights that a wide range of construction industry professionals and contractors may find useful.

Monitoring urban growth and land-use change is an important issue for sustainable infrastructure planning. Rapid urban development, sprawl and increasing population pressure, particularly in developing nations, are resulting in deterioration of infrastructure facilities, loss of productive agricultural lands and open spaces, pollution, health hazards and micro-climatic changes. In addressing these issues effectively, it is crucial to collect up-to-date and accurate data and monitor the changing environment at regular intervals. This chapter discusses the role of geospatial technologies for mapping and monitoring the changing environment and urban structure, where such technologies are highly useful for sustainable infrastructure planning and provision.

The purpose of this paper is to identify and recommend the emergence of an academic research methodology for Journalism the academic discipline, through reviewing various journalistic methods of research – those making up a key element in such methodology. Its focus is on journalistic styles of work employed in academic contexts especially research on mass media issues. It proposes that channelling such activity into disciplined academic forms will enhance both: allowing the former to provide more durable and deeper outcomes, injecting additional energy and intensity of purpose into the latter. It will briefly consider characteristics of research methodologies and methods, generally; characteristics of the Journalism discipline, and its relationship with mass media industries and professions. The model of journalism used here is the Western liberal stream. A proposition is made, that teaching and research in universities focused on professional preparation of journalists, has developed so that it is a mature academic discipline. Its adherents are for the most part academics with background in journalistic practice, and so able to deploy intellectual skills of journalists, while also accredited with Higher Degrees principally in humanities. Research produced in this discipline area stands to show two characteristics: (a) it employs practices used generally in academic research, e.g. qualitative research methods such as ethnographic studies or participant observation, or review of documents including archived media products, and (b) within such contexts it may use more specifically journalistic techniques, e.g. interviewing styles, reflection on practice of journalism, and in creative practice research, journalistic forms of writing – highlighting journalistic / practitioner capabilities of the author. So the Journalism discipline, as a discipline closely allied to a working profession, is described as one where individual professional skills and background preparation for media work will be applicable to academic research. In this connection the core modus operandi will be the directly research-related practices of: insistent establishment of facts, adept crafting of reportage, and economising well with time. Prospective fields for continuing research are described:- work in new media; closer investigation of relations among media producers and audiences; journalism as creative practice, and general publishing by journalists, e.g. writing histories.

The discourse surrounding recent Aboriginal social policy regularly refers to pragmatism and partnership. In a simpler world, we might call this ‘getting things done with Aboriginal people.’ To that extent, the discourse draws on an indisputable common sense, and it is not surprising that a variety of political agendas can be packaged within such language. While many things need to be done, the quantity and particularly the quality of social networks required to take effective policy into effective practice is something we ought to consider more carefully. This is where the concept of social capital could be useful, since it focuses attention on the social resources required to construct social policy, as well as the social resources that could be produced by effective social policy. Partnerships and pragmatism are therefore related at a most fundamental level in terms of social policy. We question whether this important conceptual bedrock has been fully explored. Hence we review here some recent ‘big plans’ for Aboriginal Australia, and ask whether the size of the theory matches the size of the plans.

Are the Academy Awards heading towards an identity crisis? This year's Academy Awards have been characterised by a major disconnect between the most popular films at the box office and socially important films deemed the 'best pictures' by the Academy. Will the popularity of a film always remain inferior to whether or not it tackles serious social issues? Can popularity in its own right ever become indicative of a film's worth? Or should the awards retain their artistic integrity and suffer declining audiences and any criticisms they receive to maintain the respect they garner within the film industry? Whatever the answers may be, the winner of this year's Academy Awards was art over commerce, but this may not always be the case.
