Training complete engineers: Global enterprise and engineering education     

Erik De Graaff  Wim Ravesteijn 《European Journal of Engineering Education》2001,26(4):419-427

For the past few years a discussion has been going on about the specific skills and knowledge a complete engineer should possess. Apart form this discussion, a separate debate has focused on the content of an engineer's education. This article is a combination of two joint papers (De Graaff and Ravesteijn 2000, Ravesteijn and De Graaff 2000) bearing on these respective subjects, presented by the authors at the SEFI 2000 conference in Paris. The demands from industry that engineers of the future will have to meet are summarized and related to characteristics of modern training methods. It is argued that a new view on the content of the engineer's education implies, at least to a certain extent, a new set of educational tools.  相似文献

A case of IgA multiple myeloma: Nutritional perspective in diagnostic testing     

J. I. Anetor  F I Ajose  T. S Akingbola 《Indian journal of clinical biochemistry : IJCB》2005,20(1):193-197

A 64-year-old security guard and longstanding known hypertensive presented with hypertensive heart disease (HHD), weight loss, an enlarged prostate, and a spontaneously fractured rib. Malignancy of the prostate with possible metastases to the ribs was strongly suspected. Biochemical profiling revealed a paraprotein. Other biochemical and hematological correlates that were on hand before serum protein electrophoresis were rather atypical. Paraprotein studies by immunofixation revealed IgA myelomatosis. Unlike previous reports from Caucasians there was normocalcaemia, normal protein level, microcytic hypochromia, low MCHC, cholesterol level at the lower limit of the reference range and normal urea level (in the face of markedly raised creatinine level). Nutritional modulation of the classical laboratory features of this disease may account for the fairly atypical laboratory picture. The need to appreciate the influence of nutritional status on the laboratory (especially biochemical) features of a disease and thus interpretation of diagnostic tests appears of exceptional current importance, given the widening gap in socioeconomic status and the level of poverty between the resource poor and developed countries from which the classical, clinical and laboratory features of most diseases were first described. This case report reminds of the need not only to recognize theoretically the impact of nutritional status on the laboratory characteristics of a disease but of the practical application of the nutritional perspective in the interpretation of diagnostic investigations, especially in nutritionally disadvantaged communities.  相似文献   

Evaluation of ovulisa: An indigenous ELISA kit for detection of ovulation     

G. M. Sankolli  M. I. Khatkhatay  M. P. Desai  D. K. Pardhe  P. C. Ishrad  U. M. Joshi 《Indian journal of clinical biochemistry : IJCB》1992,7(1):71-74

Aprototype kit for the detection of occurrence of ovulation based on urinary pregnanediol glucuronide estimations by ELISA was developed in our laboratory. This kit was sent for evaluation at 4 centres in Bombay and Pune, India. The diagnosis of ovulation/anovulation based on the results of the kit is comparable with that based on reference parameters commonly used (ultrasonography of ovarian follicles and serum progesterone estimations). The accuracy of the test was 93.5%, specificity was 87.5% and sensitivity was 95.7%. This rapid indigenous test can be very useful in assessing ovulatory status of the woman by the clinicians in their offices.  相似文献

Externalities, technological complementarities and sustained economic growth     

Kenneth I. Carlaw  Richard G. Lipsey   《Research Policy》2002,31(8-9)

Externalities as conventionally defined miss many of the spillovers that are both causes and consequences of the technological changes that underlie economic growth. We introduce a much wider concept called technological complementarities. New general purpose technologies (GPTs) rejuvenate the growth process by creating technological complementarities, which are adequately measured neither by total factor productivity (TFP) nor by externalities. There would be major gains from technological change even if the returns on capital invested in innovation never exceeded the returns on investing in existing technologies so that there were neither externalities nor positive changes in TFP.  相似文献
