Selected AbstractsHow is Education Possible?EDUCATIONAL PHILOSOPHY AND THEORY, Issue 1 2001Preliminary investigations for a theory of education The following text is the result of our ongoing discussions about the notion of intersubjectivity and its significance for an understanding of the process of education. Rather than merging our sometimes diverging ideas into one single line of argument, we decided to try if we could make the movement of divergence and convergence of our thoughts visible in the text itself. Although we definitely explore different pathways, these pathways lead to a similar insight. This is, that it is not the educator who educates, but that it is the educational ,situation',a situation constituted though not determined by the interaction between the educator and the student,which educates. This educational situation, which one of us describes as an ,in between space', emerges from the interaction between the educator and the student. In this respect we can say that it results from the difference between the partners in education. The in-between space of education is an emerging reality, which not only comes into existence as a result of the difference between the partners in education but in fact only exists in this difference. It is precisely in this respect that the form of the following article provides an example of what we want to say about the process of education. The point is, to put it briefly, that this article contains or expresses a meaning that results from the difference between the two texts, but this meaning is neither something that can be attributed to the two texts as such (in this sense this emerging meaning is constituted though not determined by the two texts), nor,and this is crucial,is it something that can be articulated in any positive way in a third text. The interaction between our two texts therefore creates a reality that results from the difference between the texts and only exists in this difference. The order of authorship expresses the fact that the first author wrote the left column and the second author the right column.

The large-area Ag-capped Au nanopillar array has potential in trace detection of special chemicals. [source] Allergic contact dermatitis to mango fleshINTERNATIONAL JOURNAL OF DERMATOLOGY, Issue 3 2004Sari Weinstein MD A 22-year-old white female student presented to the Emergency Department with a 2-day history of patchy pruritic erythema of the face, neck, and arms with periorbital edema. The eruption began as an isolated patch of nasal erythema, with subsequent extension to involve the entire face. Within 2 days, fine pinpoint papules were noted on the face, anterior chest, neck, and upper extremities. Periorbital edema was present without intraoral abnormalities or laryngeal changes. An erythematous, mildly lichenified plaque was noted on the ventral left wrist. The past medical history was significant for two similar, milder episodes of allergic reactions of uncertain etiology occurring within the previous 2 months. The previous eruptions resolved after treatment with oral loratodine and topical fluocinonide cream 0.05%. The patient denied any history of contact urticaria or new household or personal hygiene contactants, although she did report frequent ingestion of peeled mangoes. Her brother had a history of eczematous dermatitis. In the Emergency Department, the patient was administered intravenous diphenhydramine and a single 50 mg dose of oral prednisone. She continued treatment with a 5-day course of prednisone, 50 mg daily, with loratodine, 20 mg daily, and diphenhydramine as needed; however, no symptomatic improvement was seen over 4 days. She was then advised to restart fluocinonide cream twice daily. Patch testing was performed to the North American Contact Dermatitis Group Standard Series utilizing methods of the International Contact Dermatitis research group with Finn chambers. Mango skin and mango flesh harvested 5 mm below the skin surface were also placed in duplicate and tested under Finn chambers. Positive (1+) reactions were noted to nickel and p -tertbutylphenol formaldehyde resin, and bullous reactions were found to mango skin and surface flesh in duplicate (Fig. 1). Complete avoidance of mango led to resolution of the initial eruption. The clinical relevance of nickel and p -tertbutylphenol formaldehyde resin was thought to be associated with the wrist lesion immediately below a glued portion of a wristwatch strap and metal clasp.
