Introduced mammals are major drivers of extinction. Feral goats (Capra hircus) are particularly devastating to island ecosystems, causing direct and indirect impacts through overgrazing, which often results in ecosystem degradation and biodiversity loss. Removing goat populations from islands is a powerful conservation tool to prevent extinctions and restore ecosystems. Goats have been eradicated successfully from 120 islands worldwide. With newly developed technology and techniques, island size is perhaps no longer a limiting factor in the successful removal of introduced goat populations. Furthermore,. the use of global positioning systems, geographic information systems, aerial hunting by helicopter specialized bunting dogs, and Judas goats has dramatically increased efficiency and significantly reduced the duration of eradication campaigns. Intensive monitoring programs are also critical for successful eradications. Because of the presence of humans with domestic goat populations on large islands, future island conservation actions will require eradication programs that involve local island inhabitants in a collaborative approach with biologists, sociologists, and educators. Given the clear biodiversity benefits, introduced goat populations should be routinely removed from islands.

Introduced mammals are major drivers of extinction and ecosystem change. As omnivores, feral pigs (Sus scrofa) are responsible for wholesale adverse effects on islands. Here, we report on the eradication of feral pigs from Santiago Island in the Galápagos Archipelago, Ecuador, which is the largest insular pig removal to date. Using a combination of ground hunting and poisoning, over 18,000 pigs were removed during this 30-year eradication campaign. A sustained effort, an effective poisoning campaign concurrent with the hunting program, access to animals by cutting more trails, and an intensive monitoring program all proved critical to the successful eradication. While low and fluctuating control efforts may help protect select native species, current eradication methods, limited conservation funds, and the potential negative non-target impacts of sustained control efforts all favor an intense eradication effort, rather than a sustained control program. The successful removal of pigs from Santiago Island sets a new precedent, nearly doubling the current size of a successful eradication, and is leading to more ambitious projects. However, now we must turn toward increasing eradication efficiency. Given limited conservation funds, we can no longer afford to spend decades removing introduced mammals from islands.

This paper presents a critical comparison of major changes in engineering education in both Australia and Europe. European engineering programs are currently being reshaped by the Bologna process, representing a move towards quality assurance in higher education and the mutual recognition of degrees among universities across Europe. Engineering education in Australia underwent a transformation after the 1996 review of engineering education1. The paper discusses the recent European developments in order to give up-to-date information on this fast changing and sometimes obscure process. The comparison draws on the implications of the Bologna Process on the German engineering education system as an example. It concludes with issues of particular interest, which can help to inform the international discussion on how to meet today’s challenges for engineering education. These issues include ways of achieving diversityamong engineering programs, means of enabling student and staff mobility, and the preparation of engineering students for professional practic e through engineering education. As a result, the benefits of outcomes based approaches in education are discussed. This leads to an outlook for further research into the broader attributes required by future professional engineers. © 2005, Australasian Association for Engineering Education

There has been a strong move towards entrepreneurial education in high schools and at universities over the past few years. This has been echoed by a call from state governments around Australia to promote enterprise thinking and education in high schools. It also parallels the push within engineering to learn across the traditional boundaries , particularly between engineering and business. To meet this call, The Engineering Link Group (TELG) developed the Future Engineers Australia Management Project (FEAMP) in 2003. The project is based around Enterprise Education, and was inspired by the Smallpeice Year 12 Engineering Management course in the UK. The idea was to take high school students in years 11 and 12 and turn them into ‘engineering entrepreneurs’. This paper presents the design, development and evaluation of FEAMP as a five day residential course for year 11 and 12 students who want to learn more about being entrepreneurs and managers. It is a hands-on activity where the students invent, develop and sell an engineering concept to venture capitalists and ultimately to customers at a trade fair. It has been run successfully for two years, going from strength to strength. © 2005, Australasian Association for Engineering Education

Sustainable design education is vital for engineering students. This is to allow them to meet the challenges both engineering and the wider community will face in the future. This need has not only been mandated by Engineers Australia’s graduate attributes from an Australian perspective, but more widely the issue of sustainability is one of the greatest challenges humanity has ever faced. Engineers need to be at the forefront of this challenge, because we can not only do the greatest good, but have the potential to cause the greatest harm. The biggest question with respect to the education of engineers about sustainable design is what do engineers need to know, and how best to enable this learning. This paper argues that since the entire phenomenon of sustainable design is constantly growing and changing, it is only by looking at practitioners currently trying design sustainably, and their ways of experiencing sustainable design, can we hope to articulate what it is, and therefore what and how we need to teach engineering students. It also argues that to accommodate sustainable design within engineering, we need to go further and transform the engineering profession to enable it to meet the challenges that sustainability presents. © 2005, Australasian Association for Engineering Education

Biodiversity citizen science projects are growing in number, size, and scope, and are gaining recognition as valuable data sources that build public engagement. Yet publication rates indicate that citizen science is still infrequently used as a primary tool for conservation research and the causes of this apparent disconnect have not been quantitatively evaluated. To uncover the barriers to the use of citizen science as a research tool, we surveyed professional biodiversity scientists (n = 423) and citizen science project managers (n = 125). We conducted three analyses using non-parametric recursive modeling (random forest), using questions that addressed: scientists' perceptions and preferences regarding citizen science, scientists' requirements for their own data, and the actual practices of citizen science projects. For all three analyses we identified the most important factors that influence the probability of publication using citizen science data. Four general barriers emerged: a narrow awareness among scientists of citizen science projects that match their needs; the fact that not all biodiversity science is well-suited for citizen science; inconsistency in data quality across citizen science projects; and bias among scientists for certain data sources (institutions and ages/education levels of data collectors). Notably, we find limited evidence to suggest a relationship between citizen science projects that satisfy scientists' biases and data quality or probability of publication. These results illuminate the need for greater visibility of citizen science practices with respect to the requirements of biodiversity science and show that addressing bias among scientists could improve application of citizen science in conservation.

Notre étude porte le western crépusculaire et cherche plus précisément à extraire le « crépusculaire » du genre. L'épithète « crépusculaire », héritée du vocabulaire critique des années 1960 et 1970, définit généralement un nombre relativement restreint d'œuvres dont le récit met en scène des cowboys vieillissants dans un style qui privilégie un réalisme esthétique et psychologique, fréquemment associé à un révisionnisme historique, voire au « western pro-indien », mais qui se démarque par sa propension à filmer des protagonistes fatigués et dépassés par la marche de l'Histoire. Par un détour sur les formes littéraires ayant comme contexte diégétique l’Ouest américain (dime-novel et romans de la frontière), nous effectuons des allers et retours entre les formes épique et romanesque, entre l’Histoire et son mythe, entre le littéraire et le filmique pour mieux saisir la relation dyadique qu’entretient le western avec l’écriture, d’une part monumentale et d’autre part critique, de l’Histoire. Moins intéressée à l’esthétique des images qu’aux aspects narratologiques du film pris comme texte, notre approche tire profit des analyses littéraires pour remettre en cause les classifications étanches qui ont marqué l’évolution du western cinématographique. Nous étudions, à partir des intuitions d’André Bazin au sujet du sur-western, les modulations narratives du western ainsi que l’émergence d’une conscience critique à partir de ses héros mythologiques (notamment le cow-boy). Notre approche est à la fois épistémologique et transhistorique en ce qu’elle cherche à dégager du western crépusculaire un genre au-delà des genres, fondé sur une incitation à la narrativisation crépusculaire de la part du spectateur. Cette dernière, concentrée par une approche deleuzienne de l’image-cristal, renvoie non plus seulement à une conception existentialiste du personnage dans l’Histoire, mais aussi à une mise en relief pointue du hors-cadre du cinéma, moment de clairvoyance à la fois pragmatique et historicisant que nous définissons comme une image-fin, une image chronogénétique relevant de la contemporanéité de ses figures et de leurs auteurs.

Depuis les années 2000, l’apparition du terme Bromance marque la culture populaire américaine. Cette notion est apparue pour définir les amitiés entre hommes au cinéma, à la télévision et sur Internet. Les films de Bromance, caractérisés par une multitude de scènes de déclaration d’amour entre hommes, traduisent bien cette nouvelle façon d’aborder l’amitié au masculin. À travers les définitions de la masculinité dans ces films, l’enjeu de l’hétérosexualité demeure omniprésent. Malgré la fragilisation de certains stéréotypes traditionnels liés au masculin, il n’en demeure pas moins que la notion de «vraie» masculinité persiste et demeure systématiquement liée à l’hétérosexualité des hommes qui partagent cette amitié particulière qu’on appelle Bromance. Dans cette optique, plusieurs stratégies se manifestent pour prouver la masculinité et donc l’hétérosexualité des protagonistes, mais l’une d’entre elles semble être au cœur de ces films. Cette stratégie s’incarne sous la forme d’une compétition entre hommes qui mise sur la capacité à performer un acte conventionnellement associé à l’homosexualité. Sur Internet, des vidéos qui prennent le nom « Gay Chicken » présentent des hommes qui s’embrassent et qui se touchent sans être dérangés ou ébranlés. C’est la capacité à être calme et en contrôle en restant insensible au corps d’un autre homme qui démontrerait le côté inébranlable de son hétérosexualité et donc de sa masculinité. C’est cet esprit du « Gay Chicken » qui se retrouve un peu partout dans l’univers des films de Bromance. Paradoxalement, ces nouveaux «modèles» d’homme doivent pouvoir à la fois incarner une masculinité plus flexible, plus ouverte et sensible, mais doivent également prouver leur virilité. Cette « masculinité contemporaine » brouille les cartes entre ce qui est viril et ce qui ne l’est pas, entre ce qui est féminin et ce qui ne l’est pas et entre ce qui est homosexuel et ce qui ne l’est pas. Les relations homosociales dans le cadre de Bromances présentent alors des opportunités indispensables pour prouver à tous la force de son hétérosexualité. Ce travail de recherche se penchera donc plus précisément sur les paradoxes d’une « masculinité contemporaine » intimement liée à l’orientation hétérosexuelle, par l’entremise de certains films issus de la culture populaire américaine associée à la Bromance. L’objectif est de montrer comment ces films sont des manifestations significatives d’une nouvelle forme d’affirmation identitaire masculine qui passe par des relations homosociales où les tensions et sous-textes homosexuels se multiplient et doivent être réprimés ou invalidés continuellement.
