This serves as a unique and valuable means of the public communication of science and technology and informal science education activities, with the public at the centre of the process. To achieve this, SRWs integrate action and reflection not as a dichotomy, but as a complementary relation in which sensorial interaction is not a thoughtless process and mental activity is not disembodied. In this way, SRWs create virtuous cycles of meaningful learning.However, SRW practitioners thus far have not paid enough attention to the development of a theoretical foundation to support their strategies;they remain highly dependent on empirical experience and tacit knowledge. The little attention paid to the creation of a conceptual framework represents a critical barrier for reflection, discussion and, with them, the maturation of the SRW community.This work links a characterization of the SRW, built upon empirical experiences, to a variety of learning theories to identify an essential basis for discussion on the subject. Our objective is to complement the rich empirical tradition of the SRW with analytic elements intended to encourage discussion and promote—as tends to happen in activities with the public—virtuous cycles of theory and practice.展开更多

It identifies opportunities to remove unnecessary costs while assuring that quality, reliability, performance, and other critical factors will meet or exceed the customers’ expectations. It has been widely used in the construction industry in a number of countries. A recent survey, however, revealed several problems that hinder the wider use of this methodology in the industry. To overcome these problems, a feasibility study has been conducted to investigate whether or not a Group Support System (GSS) can support collaborative works in VM workshops. This paper introduces the development and structure of a prototype GSS which is designed to support the collaborative works of stakeholders in VM workshops. It begins with an introduction to the conceptual GSS framework and job plan, illustrating what GSS supports can be provided to VM workshops. This is followed by a detailed description of the GSS prototype system to demonstrate how these supports can be performed as an integrated computer system. The testing of the system is also discussed. The research findings provide strong evidence in supporting the notion of using GSS to improve VM implementation. The information support of GSS has been ranked to be the most useful GSS functions and most of the practitioners interviewed are highly interested in applying GSS to support VM workshops in the future.展开更多

We assessed the effect of activities of mechanics in auto-mobile workshops on the quality of groundwater sources. Water samples were collected from hand dug wells situated within 0 to 50 metres in twenty auto-mobile workshops randomly selected across three zones. A residential area was selected as the control site. Analysis of water for some physico-chemical parameters (pH, TDS, Electrical Conductivity, Alkalinity, Oil and Grease) and the heavy metals (Cu, Cd, Cr, and Pb) was done using standard methods. Sanitary inspection was also carried out at each well location. Results were compared with the control and regulatory standards Nigerian Industrial Standard for Drinking Water Quality (NISDQW) and World Health Organization (WHO) guidelines for drinking water quality. Results revealed that mean values of pH, TDS and Electrical conductivity for the three zones, Alphonso, Temidire, and Ojoo were within WHO limits. The concentrations of Cu, Cd Cr and Pb in the water samples ranged from 0.02 - 6.12 mg/l, 0.1 - 2.19 mg/l, 0.2 - 0.79 mg/l and 0.02 - 35.8 mg/l across the three zones respectively. Mean concentrations of Cu (mg/l) were significantly higher in Alphonso (2.5 ± 2.06) than in other zones. Mean concentration of Cr (mg/l) was 0.34 ± 0.28, 0.37 ± 0.13 and 0.31 ± 0.3 for Alphonso, Temidire and Ojoo respectively. Cadmium was also present in all the zones but Pb was only detected in Alphonso. The mean concentrations for heavy metals were significantly higher when compared with the permissible limits for both NISDQW and WHO. The degree of groundwater contamination indicates poor water quality in the study area, and this requires regular monitoring. Enforcement of environmental regulations guiding activities of auto-mechanics should be done so that they can embrace environmentally friendly practices to reduce pollution.展开更多

These online workshops using PNCM helped achieve the original goals and the results revealed a positive outcome of the workshops.

By applying this model to medical care, nursing staff can be stimulated to think about specific nursing skills, and at the same time, nursing staff can be stimulated to continuously improve their nursing skills. Generally speaking, through the workshop mode, the person in charge can organize nursing course teaching, learning and training, vocational training, etc., so that all nursing staff can explore a specific problem together and gradually improve their comprehensive skills. This paper mainly explores the concept and characteristics of the workshop model and its actual application in static therapy and nursing, hoping to provide reference for the research of relevant scholars.展开更多

At least two types of training can be envisioned in order to produce meaningful results, quality publications and successful grant applications： （1） immediate short-term training workshops and （2） long-term graduate education or visiting scientist programs. We aimed to fill the former need by providing a comprehensive hands-on training course in genomics, proteomics and informatics in a coherent, experimentally-based framework. This was accomplished through a National Heart, Lung, and Blood Institute （NHLBI）-sponsored 10-day Genomics and Proteomics Hands-on Workshop held at National Jewish Health （NJH） and the University of Colorado School of Medicine （UCD）. The course content included comprehensive lectures and laboratories in mass spectrometry and genomics technologies, extensive hands-on experience with instrumentation and software, video demonstrations, optional workshops, online sessions, invited keynote speakers, and local and national vip faculty. Here we describe the detailed curriculum and present the results of short- and long-term evaluations from course attendees. Our educational program consis- tently received positive reviews from participants and had a substantial impact on grant writing and review, manuscript submissions and publications.展开更多

文摘Genomics and proteomics have emerged as key technologies in biomedical research, resulting in a surge of interest in training by investigators keen to incorporate these technologies into their research. At least two types of training can be envisioned in order to produce meaningful results, quality publications and successful grant applications： （1） immediate short-term training workshops and （2） long-term graduate education or visiting scientist programs. We aimed to fill the former need by providing a comprehensive hands-on training course in genomics, proteomics and informatics in a coherent, experimentally-based framework. This was accomplished through a National Heart, Lung, and Blood Institute （NHLBI）-sponsored 10-day Genomics and Proteomics Hands-on Workshop held at National Jewish Health （NJH） and the University of Colorado School of Medicine （UCD）.

Here we describe the detailed curriculum and present the results of short- and long-term evaluations from course attendees. Our educational program consis- tently received positive reviews from participants and had a substantial impact on grant writing and review, manuscript submissions and publications.
