3D Pose from Three Corresponding Points Under Weak-Perspective Projection

Model-based object recognition commonly involves using a minimal set of matched model and image points to compute the pose of the model in image coordinates. Furthermore, recognition systems often rely on the "weak-perspective" imaging model in place of the perspective imaging model. This paper discusses computing the pose of a model from three corresponding points under weak-perspective projection. A new solution to the problem is proposed which, like previous solutins, involves solving a biquadratic equation. Here the biquadratic is motivate geometrically and its solutions, comprised of an actual and a false solution, are interpreted graphically. The final equations take a new form, which lead to a simple expression for the image position of any unmatched model point.

Recovery of Three-Dimensional Objects from Single Perspective Images

Any three-dimensional wire-frame object constructed out of parallelograms can be recovered from a single perspective two-dimensional image. A procedure for performing the recovery is given.

Reflective writing: The student nurse's perspective on reflective writing and poetry writing.

Summary Background Reflective writing is a mandatory part of nurse education but how students develop their skills and use reflection as part of their experiential learning remains relatively unknown. Understanding reflective writing in all forms from the perspective of a student nurse is therefore important. Objectives To explore the use of reflective writing and the use of poetry in pre-registered nursing students. Design A qualitative design was employed to explore reflective writing in pre-registered nursing students. Setting A small university in Scotland. Participants BSc (Hons) Adult and Mental Health Pre-registration Student Nurses. Methods Two focus groups were conducted with 10 student nurses during March 2012. Data was analysed thematically using the framework of McCarthy (1999). Results Students found the process of reflective writing daunting but valued it over time. Current educational methods, such as assessing reflective accounts, often lead to the ‘narrative’ being watered down and the student feeling judged. Despite this, reflection made students feel responsible for their own learning and research on the topic. Some students felt the use of models of reflection constricting, whilst poetry freed up their expression allowing them to demonstrate the compassion for their patient under their care. Conclusions Poetry writing gives students the opportunity for freedom of expression, personal satisfaction and a closer connection with their patients, which the more formal approach to reflective writing did not offer. There is a need for students to have a safe and supportive forum in which to express and have their experiences acknowledged without the fear of being judged.

Synthetic biology: a utilitarian perspective

I examine the positive and negative features of synthetic biology (‘SynBio’) from a utilitarian ethical perspective. The potential beneficial outcomes from SynBio in the context of medicine are substantial; however it is not presently possible to predict precise outcomes due to the nascent state of the field. Potential negative outcomes from SynBio also exist, including iatrogenesis and bioterrorism; however it is not yet possible to quantify these risks. I argue that the application of a ‘precautionary’ approach to SynBio is ethically fraught, as is the notion that SynBio-associated knowledge ought to be restricted. I conclude that utilitarians ought to support a broadly laissez-faire stance in respect of SynBio.

Listening to Anima Mundi: The Organic Metaphor in the Cosmoecological Perspective

This paper is an attempt to revise an organic epistemological approach toward nature. The sources for such a view are found in the metaphor of the Earth as a living organism, which can be traced even to ancient Greek philosophy. Drawing on the notion of cosmoecology and the Gaia-Uranus Hypothesis, we re-think and supplement the holistic perspective in environmental ethics by emphasizing the role of the embodied of nature, and by turning our attention back “from the heavens to earth”.

Sytuacja komunikacyjna w kulturze archaicznej a symboliczność komunikacji

Celem niniejszego artykułu jest wskazanie i przedyskutowanie (z perspektywy filozofii komunikacji i teorii komunikacji) kilku konsekwencji wynikających z badań nad fenomenem komunikacji. Oprócz zagadnień związanych z filozoficznym ujęciem procesu komunikacji podejmuje się również problematykę wyłonienia się myślenia metafizycznego w starożytnej Grecji. Artykuł ten jest próbą wskazania warunków, które należy spełnić, aby prowadzić filozoficznie uprawnioną refleksję nad procesem komunikacji. Całość została podzielona na trzy główne działy: w pierwszym są prezentowane dwa poziomy rekonstrukcji sytuacji komunikacyjnej w kulturze archaicznej; w drugim rozważa się zagadnienie początków relacji symbolizowania oraz zjednoczenia myślenia i działania. Trzecia część poświęcona jest źródłom myślenia metafizycznego oraz symboliczności komunikacji. Najistotniejszy wniosek wynikający z rozważań zawarty w artykule dotyczy nie-symbolicznego ujęcia procesów komunikacyjnych.
