A new educational technology for media and communication studies : mapping media in Australia and Sweden

This chapter reports on Australian and Swedish experiences in the iterative design, development, and ongoing use of interactive educational systems we call ‘Media Maps.’ Like maps in general, Media Maps are usefully understood as complex cultural technologies; that is, they are not only physical objects, tools and artefacts, but also information creation and distribution technologies, the use and development of which are embedded in systems of knowledge and social meaning. Drawing upon Australian and Swedish experiences with one Media Map technology, this paper illustrates this three-layered approach to the development of media mapping. It shows how media mapping is being used to create authentic learning experiences for students preparing for work in the rapidly evolving media and communication industries. We also contextualise media mapping as a response to various challenges for curriculum and learning design in Media and Communication Studies that arise from shifts in tertiary education policy in a global knowledge economy.

Disposable maps : ad hoc location sharing

The gathering of people in everyday life is intertwined with travelling to negotiated locations. As a result, mobile phones are often used to rearrange meetings when one or more participants are late or cannot make it on time. Our research is based on the hypothesis that the provision of location data can enhance the experience of people who are meeting each other in different locations. This paper presents work-in-progress on a novel approach to share one’s location data in real-time which is visualised on a web-based map in a privacy conscious way. Disposable Maps allows users to select contacts from their phone’s address book who then receive up-to-date location data. The utilisation of peer-to-peer notifications and the application of unique URLs for location storage and presentation enable location sharing whilst ensuring users’ location privacy. In contrast to other location sharing services like Google Latitude, Disposable Maps enables ad hoc location sharing to actively selected location receivers for a fixed period of time in a specific given situation. We present first insights from an initial application user test and show future work on the approach of disposable information allocation.

Bringing the internet down to earth : emerging spaces of locative media

Web 1.0 referred to the early, read-only internet; Web 2.0 refers to the ‘read-write web’ in which users actively contribute to as well as consume online content; Web 3.0 is now being used to refer to the convergence of mobile and Web 2.0 technologies and applications. One of the most important developments in mobile 3.0 is geography: with many mobile phones now equipped with GPS, mobiles promise to “bring the internet down to earth” through geographically-aware, or locative media. The internet was earlier heralded as “the death of geography” with predictions that with anyone able to access information from anywhere, geography would no longer matter. But mobiles are disproving this. GPS allows the location of the user to be pinpointed, and the mobile internet allows the user to access locally-relevant information, or to upload content which is geotagged to the specific location. It also allows locally-specific content to be sent to the user when the user enters a specific space. Location-based services are one of the fastest-growing segments of the mobile internet market: the 2008 AIMIA report indicates that user access of local maps increased by 347% over the previous 12 months, and restaurant guides/reviews increased by 174%. The central tenet of cultural geography is that places are culturally-constructed, comprised of the physical space itself, culturally-inflected perceptions of that space, and people’s experiences of the space (LeFebvre 1991). This paper takes a cultural geographical approach to locative media, anatomising the various spaces which have emerged through locative media, or “the geoweb” (Lake 2004). The geoweb is such a new concept that to date, critical discourse has treated it as a somewhat homogenous spatial formation. In order to counter this, and in order to demonstrate the dynamic complexity of the emerging spaces of the geoweb, the paper provides a topography of different types of locative media space: including the personal/aesthetic in which individual users geotag specific physical sites with their own content and meanings; the commercial, like the billboards which speak to individuals as they pass in Minority Report; and the social, in which one’s location is defined by the proximity of friends rather than by geography.

Which way up? Reading and drawing maps of the blogosphere

Mapping the physical world, the arrangement of continents and oceans, cities and villages, mountains and deserts, while not without its own contentious aspects, can at least draw upon centuries of previous work in cartography and discovery. To map virtual spaces is another challenge altogether. Are cartographic conventions applicable to depictions of the blogosphere, or the internet in general? Is a more mathematical approach required to even start to make sense of the shape of the blogosphere, to understand the network created by and between blogs? With my research comparing information flows in the Australian and French political blogs, visualising the data obtained is important as it can demonstrate the spread of ideas and topics across blogs. However, how best to depict the flows, links, and the spaces between is still unclear. Is network theory and systems of hubs and nodes more relevant than mass communication theories to the research at hand, influencing the nature of any map produced? Is it even a good idea to try and apply boundaries like ‘Australian’ and ‘French’ to parts of a map that does not reflect international borders or the Mercator projection? While drawing upon some of my work-in-progress, this paper will also evaluate previous maps of the blogosphere and approaches to depicting networks of blogs. As such, the paper will provide a greater awareness of the tools available and the strengths and limitations of mapping methodologies, helping to shape the direction of my research in a field still very much under development.

New maps of learning for quality art education : what pre-service teachers should learn and be able to do

It would be a rare thing to visit an early years setting or classroom in Australia that does not display examples of young children’s artworks. This practice serves to give schools a particular ‘look’, but is no guarantee of quality art education. The Australian National Review of Visual Arts Education (NRVE) (2009) has called for changes to visual art education in schools. The planned new National Curriculum includes the arts (music, dance, drama, media and visual arts) as one of the five learning areas. Research shows that it is the classroom teacher that makes the difference, and teacher education has a large part to play in reforms to art education. This paper provides an account of one foundation unit of study (Unit 1) for first year university students enrolled in a 4-year Bachelor degree program who are preparing to teach in the early years (0–8 years). To prepare pre-service teachers to meet the needs of children in the 21st century, Unit 1 blends old and new ways of seeing art, child and pedagogy. Claims for the effectiveness of this model are supported with evidence-based research, conducted over the six years of iterations and ongoing development of Unit 1.

Social media as online information grounds : a preliminary conceptual framework

Researchers are increasingly grappling with ways of theorizing social media and its use. This review essay proposes that the theory of Information Grounds (IG) may provide a valuable lens for understanding how social media fosters collaboration and social engagement among information professionals. The paper presents literature that helps us understand how social media can be seen as IG, and maps the characteristics of social media to the seven propositions of IG theory. This work is part of a wider study investigating the ways in which Information Technology (IT) professionals experience social media.

Cache-and-Relay Streaming Media Delivery for Asynchronous Clients

We consider the problem of delivering popular streaming media to a large number of asynchronous clients. We propose and evaluate a cache-and-relay end-system multicast approach, whereby a client joining a multicast session caches the stream, and if needed, relays that stream to neighboring clients which may join the multicast session at some later time. This cache-and-relay approach is fully distributed, scalable, and efficient in terms of network link cost. In this paper we analytically derive bounds on the network link cost of our cache-and-relay approach, and we evaluate its performance under assumptions of limited client bandwidth and limited client cache capacity. When client bandwidth is limited, we show that although finding an optimal solution is NP-hard, a simple greedy algorithm performs surprisingly well in that it incurs network link costs that are very close to a theoretical lower bound. When client cache capacity is limited, we show that our cache-and-relay approach can still significantly reduce network link cost. We have evaluated our cache-and-relay approach using simulations over large, synthetic random networks, power-law degree networks, and small-world networks, as well as over large real router-level Internet maps.

Permeability mapping in porous media by magnetization prepared centric-scan SPRITE

The ability of porous media to transmit fluids is commonly referred to as permeability. The concept of permeability is central for hydrocarbon recovery from petroleum reservoirs and for studies of groundwater flow in aquifers. Spatially resolved measurements of permeability are of great significance for fluid dynamics studies. A convenient concept of local Darcy’s law is suggested for parallel flow systems. The product of porosity and mean velocity images in the plane across the average flow direction is directly proportional to permeability. Single Point Ramped Imaging with T 1 Enhancement (SPRITE) permits reliable quantification of local fluid content and flow in porous media. It is particularly advantageous for reservoir rocks characterized by fast magnetic relaxation of a saturating fluid. Velocity encoding using the Cotts pulsed field gradient scheme improves the accuracy of measured flow parameters. The method is illustrated through measurements of 2D permeability maps in a capillary bundle, glass bead packs and composite sandstone samples.

The gendered world of sports reporting in the Australian print media

The mainstream news media have long been charged by feminist and critical media scholars of largely excluding women from its sports coverage, and concomitantly highlighting the ongoing relative absence of female sports reporters. With the 2012 London Olympic Games just past, it is timely to reflect on two areas of sports journalism that recieve sparse scholarly interest from the majority of Australian journalism academics, as technology issues and the future of journalism debates take precedence. The Olympics typically generate more media exposure for female athletes than usual, nevertheless, it remains that there are particular types of 'gender appropriate' events that attract mainstream news media attention during the Games, and other sporting events in general. This paper analyses a month of pre-Olympic sports coverage and general sports coverage in two major Australian newspapers, finding that while pre-Olympic coverage includes more women's sport than in general sport, sportsmen and men's sport remains highly privileged in both areas. The fact that horseracing recieves three times more media coverage than women's sports in this study clearly identifies sportswomen's marginalised status. The paper also maps the number of female sports reporters at these two newspapers, and concludes with some insights into a newsroom culture that typically rejects women as athletes and as sports reporters

Understanding Neural Maps with Topographica

The biological function of neurons can often be understood only in the context of large, highly interconnected networks. These networks typically form two-dimensional topographic maps, such as the retinotopic maps in mammalian visual cortex. Computational simulations of these areas have led to valuable insights about how cortical topography develops and functions, but further progress has been hindered due to the lack of appropriate simulation tools. This paper introduces the freely available Topographica maplevel simulator, originally developed at the University of Texas at Austin and now maintained at the University of Edinburgh, UK. Topographica is designed to make large-scale, detailed models practical. The goal is to allow neuroscientists and computational scientists to work together to understand how topographic maps and their connections organize and operate. This understanding will be crucial for integrating experimental observations into a comprehensive theory of brain function.

Estudios corológicos de plantas vasculares en la cuenca media del Tajo

Se ha realizado un estudio de la distribución de plantas vasculares en un territorio situado entre las provincias de Cuenca, Guadalajara, Madrid y Toledo (España). El territorio estudiado está en la Submeseta Sur de la península ibérica, al sur del Sistema Central, norte de los Montes de Toledo y oeste del Sistema Ibérico, en zonas sedimentarias con poco relieve y clima mediterráneo, con grandes contrastes de temperatura y precipitaciones muy irregulares. Coincide con las regiones naturales llamadas: “Alcarrias”, “Campiñas de Madrid y Guadalajara” y “Vegas de los ríos de la Cuenca del Tajo”. Es lo que he llamado Cuenca Media del Tajo. En una primera fase se ha estudiado la flora regional para adquirir conocimientos previos mediante las consultas bibliográficas y de herbarios, se ha contado con bases de datos disponibles para MA, MACB, MAF, JACA, AH, ABH, VAL, SALA y EMMA. Se han revisado las aportaciones propias que en los últimos años he realizado en el territorio en relación a los temas tratados en la tesis. El trabajo de campo ha consistido en la realización de inventarios de presencia de flora. Ha sido muy importante la tarea herborizadora para llegar a la correcta identificación de las especies colectadas en los inventarios. De esta forma el autor ha confeccionado un herbario propio JML que en el territorio muestreado ha reunido cerca de 15000 números en las cuatro provincias estudiadas. Se ha hecho un muestreo sistemático del territorio con unos 6000 listados de plantas. Se ha tomado como unidad de muestreo la cuadrícula de UTM de 1 km de lado incluida como una centésima parte de la cuadrícula de UTM de 10 km. Se han seguido criterios para uniformizar el muestreo. Se ha apuntado el tiempo empleado y la superficie muestreada estimada en cada toma de datos. El criterio mínimo que tienen que cumplir todas las cuadrículas en el área estudiada ha sido que para cada cuadrícula de UTM de 5 km se han realizado al menos 5 inventarios en 5 cuadrículas diferentes de UTM de 1 km y al menos en una hora de tiempo. La unidad de comparación ha sido la cuadrícula UTM de 5 km. Se han informatizado los inventarios de campo, para ello se ha creado la base de datos TESIS en Microsoft office –Access-. Las principales tablas son LOCALIDAD, en la que se anotan las características del lugar muestreado y ESPECIES, que lista las especies de flora consideradas en las cuatro provincias del estudio. Por medio de formularios se han rellenado las tablas; destaca la tabla ESPECIE INVENTARIO que relaciona las tablas ESPECIES y LOCALIDAD; esta tabla cuenta en este momento con unos 165.000 registros. En la tabla ESPECIES_FPVI se visualizan las especies recopiladas. Se ha creado un indicador llamado FPVI “Flora permanentemente visible identificable” que consiste en atribuir a cada especie unos índices que nos permiten saber si una determinada planta se puede detectar en cualquier época del año. Los resultados presentados son: Creación de la base de datos TESIS. El Catálogo Florístico de la Cuenca Media del Tajo, que es el catálogo de la flora de las cuatro provincias desde el principio de la sistemática hasta las Saxifragáceas. En total se han recopilado 1028 taxones distribuidos en 77 familias. Se ha calculado el índice FPVI, para las especies del catálogo. La finalidad para la que se ha diseñado este índice es para poder comparar territorios. Para el desarrollo de ambos resultados ha sido fundamental el desarrollo de la tabla ESPECIES_PVI de la base de datos TESIS. En la tabla ESPECIES_PVI se han apuntado las características ecológicas y se revisa la información bibliográfica disponible para cada especie; las principales fuentes de información consultadas han sido Flora iberica, el proyecto “Anthos” y las bases de datos de los herbarios. Se ha apuntado sí se ha visto, sí está protegida o sí en un endemismo. Otros resultados son: la localización de las cuadrículas de UTM de 10 km, con mayor número de endemismos o especies singulares, con mayor valor botánico. Se ha realizado un par de ejemplos de estudios de autoecología de especie, en concreto Teucrium pumilum y Clematis recta. Se han confeccionando salidas cartográficas de distribución de especies. Se ha elaborado el herbario JML. Se ha presentado una sencilla herramienta para incluir inventarios florísticos, citas corológicas, consultas de autoecología o etiquetado de pliegos de herbario. Como colofón, se ha colaborado para desarrollar una aplicación informática de visualización, análisis y estudio de la distribución de taxones vegetales, que ha utilizado como datos de partida un porcentaje importante de los obtenidos para esta tesis. ABSTRACT I have made a study of the distribution of vascular plants in a territory located between the provinces of Cuenca, Guadalajara, Madrid and Toledo (Spain). The studied area is in the “Submeseta” South of the Iberian Peninsula, south of the Central System, north of the Montes de Toledo and west of the Iberian System, in sedimentary areas with little relief and Mediterranean climate, with big temperature contrasts and irregular rainfall. Coincides with the natural regions called "Alcarrias", "countryside of Madrid and Guadalajara" and “Vegas River Tagus Basin”. This is what I have called Middle Tagus Basin. In a first step we have studied the regional flora to acquire prior knowledge through the literature and herbaria consultations, it has had available databases for MA, MACB, MAF, JACA, AH, ABH, VAL, SALA and EMMA herbaria. The contributions I have made in the last years in the territory in relation to the topics discussed in the thesis have been revised. The field work consisted of conducting inventories presence of flora. Botanize was a very important task to get to the correct identification of the species collected in inventories. In this way the author has made his own herbarium JML in the sampled area has met at least 15000 samples in the four studied provinces. There has been a systematic sampling of the territory with nearly 6,000 listings of plants. Was taken as the sampling unit grid UTM 1 km side included as a hundredth of the UTM grid of 10 km from side. Criteria have been taken to standardize the sampling. Data were taken of the time spent and the estimated sampled surface. The minimum criteria they have to meet all the grids in the study area has been that for each UTM grid of 5 km have been made at least 5 stocks in 5 different grids UTM 1 km and at least one hour of time. The unit of comparison was the UTM grid of 5 km. I have computerized inventories of field, for it was created a database in Access- Microsoft office -TESIS. The main tables are LOCALIDAD, with caracteristics of the sampled location and ESPECIES, which lists the plant species considered in the four provinces of the study, is. Through forms I filled in the tables; highlights ESPECIE INVENTARIO table that relates the tables ESPECIES and LOCALIDAD, this table is counted at the moment with about 165,000 records. The table ESPECIES FPVI visualizes all recollected species. We have created an indicator called FPVI "Flora permanently visible identifiable" that attributes to each species indices that allow us to know whether a given plant can be detected in any season. The results presented are: Creating data base TESIS. The Floristic Books Middle Tagus Basin, which is a catalog of the flora of the four provinces since the beginning of the systematic until Saxifragaceae. In total 1028 collected taxa in 77 families. We calculated FPVI index for species catalog. The purpose for which this index designed is, to compare territories. For the development of both results, it was essential to develop the table ESPECIES_PVI TESIS data base. Table ESPECIES_PVI has signed the ecological characteristics and bibliographic information available for each species is revised; the main sources of information has been Flora iberica, the Anthos project databases of herbaria. Targeted species has been recorded, when seen, protected or endemism. Have also been located UTM grids of 10 km, with the largest number of endemic or unique species and more botanical value. There have been a couple of species autecology studies, namely Teucrium pumilum and Clematis recta, as an example of this type of study. They have been putting together maps of species distribution. We made herbarium JML. I have presented a simple tool to include floristic inventories, chorological appointments, consultations or to tag autoecology herbarium specimens. To cap it has worked to develop a computer application for visualization, analysis and study of the distribution of plant taxa, which has used as input data a significant percentage of those obtained for this thesis.

The representation of the world in national Arab news agencies: an exploration of (trans)national networks in the official Arab media

The purpose of this paper is to draw a map of the representation of the world and of Arab states as reflected by the countries of the region. To do so, we have analysed the news (4,093 news randomly collected on February and August 2005) produced by the governments of the Arab states through their national news agencies. Several regional and world maps had been constructed to show the official Arab representation of the World, the Arab countries conflict agenda, the persistence of colonial ties (with the European metropolis) and the emergence of new relationships (Asian countries). The representation of the world that appeared in the analysis focuses its interest on the USA, the war in Iraq, the Israel-Palestine conflict, the United Kingdom, France, and Iran. The Arab regional powers organise the flow of information (Saudi Arabia and Egypt) and the colonial past determines the current structure of communication (French-speaking bloc and English-speaking bloc).
