In this study, we worked with second-year engineering students at an Australian university to examine previously identified threshold concepts within the theoretical framework of Possible Selves. Using workshops as the context for intensive work with students, students were encouraged to consider their future lives and work, including their engineering fears, expectations, and aspirations. The findings revealed many students to have a poor understanding of the realities of engineering work. Moreover, perceived gaps between self-efficacy and the requirements of engineering work appeared to be motivating if students deemed it possible to reduce the gap, but demotivating if they identified a characteristic over which there was perceived to be no control. The study suggests that these engineering students needed more opportunities to explore both the roles of engineers and their own possible selves. Overall, the findings indicate that higher education students may need encouragement and support to explore potential future roles, and they strengthen calls for further research in this area.  相似文献

Whilst an academic working in the arts may have been appointed as a consequence of artistic accomplishment and a capacity to teach, the research that underpins such work is an intrinsic part of its production and also needs to be recognised. In Australia, the ability of the artist‐academic to translate research into a form that is respected and rewarded is an issue of contention. This paper gathers responses to this issue. Perceptions of and attitudes to creative work as research are canvassed alongside life decisions arising from those perceptions and attitudes. This research occurs in the context of a new Australian framework for the evaluation of research. This framework offers some recognition of the research that supports creative practice. Thus, the long‐standing experience of compromise reported by the Australian artist‐academics interviewed for this study are discussed alongside new policies that seek to construct methodologies for its amelioration.  相似文献

Immediately after a recently fed rodentdemonstrator interacts with a conspecificobserver, the observer shows a substantially enhanced preference for whatever food its demonstrator ate. Here we show that (1) influence of a single, 30-min interaction with a demonstrator on an observer’s food preference lasts for at least 1 month, and (2) observers interacting on 2 successive days with a demonstrator fed a different diet on each day show significantly enhanced preferences for both diets a month later. Such enduring effects of single, brief interactions between a demonstrator rat and its observer provide an efficient means for studying physiological and behavioral substrates of long-term memory in rodents. Together with the results of previous studies of social influences on food choices of rats, the present results also suggest that rats may use information acquired from conspecifics to identify both toxic and safe foods for many weeks after they have acquired this information.  相似文献

I review literature on four different approaches to the study of traditions in animals: observation of free-living animals, laboratory experiment, armchair analysis, and field experiment. Because, by definition, a tradition entails social learning of some kind, it is difficult, perhaps impossible, to establish that a behavior is in fact traditional without knowledge of how it develops. Observations of free-living animals often provide strong circumstantial evidence of a tradition. However, even in the view of several researchers who have studied possibly traditional behaviors in natural populations, observation alone has not proven sufficient to show that social learning contributes to development of behaviors of interest. The relevance of laboratory experiments to the understanding of the development of behaviors in free-living animals is always open to challenge. Armchair analyses of field data can produce interesting hypotheses but cannot test them. Field experiments to determine how behaviors of interest develop in population members provide a promising way forward.  相似文献

In 1713, the scientific instrument-maker Jakob Leupold published designs for three machines were the first attempt to design machinery with internal moving parts that replaced human agency in creating original images. This paper first analyzes his text and engravings in order to explain how he proposed to do this, given contemporary materials and command of physical forces. Next, it characterizes the devices as a transition from concepts of incision to concepts of mirroring, taken as models of the history of mechanical reproduction. And finally, Leupold’s replacement of the sighting grid with differential gears points to a set of problems appearing in contemporary philosophy represented in Rococo artistic production of this period as well. Taking the proposed devices in context, they help to theorize the complex notions of creative activity in Rococo visual culture. Taken as an episode in the history of communications, they instance the development of conceptions of personhood and of physical forces at stake in the invention of automated media.  相似文献
