    Scholarship of Teaching and Learning (SoTL) is a fast-maturing field of study within many research-intensive universities. SoTL improves the quality of teaching, the professional development of teachers, and the recognition and appreciation of education. To encourage SoTL, it is important to know how to support teachers. This study describes two pilot initiatives with the goal to encourage and support teachers at a research-intensive university with their first SoTL project. In both pilots, a community of practice (CoP) approach was used. The experiences with the pilots were investigated with questionnaires and interviews. Based on the feedback of participants, albeit with some caution because of the relatively small sample size of this study, suggestions for future initiatives that support teachers new to SoTL at research-intensive institutes are: 1) the use of a combination of a CoP and individual guidance by experienced SoTL facilitators; 2) the creation of opportunities for formal and informal interaction to strengthen the CoP; 3) encouraging participants to work together on (shared) aligned projects; 4) the provision of structured course elements with guided discussions; 5) the provision of theoretical support regarding the principles of SoTL, for example, finding and interpreting literature, formulating a research question, and choosing the research methodology; 6) structure the inclusion of students’ participations, perspectives, and roles in SoTL; 7) some form of obligation, such as an official status of the initiative; and 8) institutional support, such as providing recognition, time, and financial support. The lessons learned in this study have relevance for all universities seeking to embrace, encourage, and support SoTL, especially for those initiating their first SoTL-supporting activities

    Inter- and intra-individual variation in earprints

    The feasibility of earprint individualization depends upon the amount of variation in prints of different ears, but also upon that in prints of a single ear. In order to determine the limits to intra-individual variation, we need to explore its potential causes. As the amount of force that is applied by the ear to the listening surface influences the appearance of the earprint, we investigated factors potentially affecting this force, such as the level and frequency of a target sound, and the level of ambient noise. We also investigated whether presence or absence of a target sound was of influence. Additionally, we explored if the duration of listening, and whether the ear had been recently cleaned or not, affected the appearance of an earprint. To evaluate the extent to which features may vary with passing time, we further attempted to determine the rate of growth of the external ear during adult life. As a next step, we then compared realistic intra-individual variation in earprints with a very small degree of inter-individual variation, i.e., that in prints of identical twins. To do so, we explored a method to fully automatically analyze prints. To our knowledge, this was the first time that any method capable of fully automated earprint comparisons has been described.LEI Universiteit Leidenniet-projectgebonden outpu

    The author investigated the possibilities for arable farms in the old fen settlements of the north-eastern Netherlands after various improvements such as in the quality of the soil and the layout. By linear programming, calculations were made for farm models differing in soil quality, accessibility of farm buildings and land for heavy transport, field size, field distance and width of the fields, and in labour force and mechanization.Farms with machines usual for the area gave insufficient scope, even under the most favourable circumstances. For reasonable incomes further mechanization was necessary. To attain maximum profit from this and from improvements as in layout, the area per man should be increased considerably.A level of mechanization with an investment of f 75,000 in machinery gave good results, if the accessibility of farm buildings was improved, fields enlarged and an area per man was above 25 ha. However, the best results could only be attained with areas per man of about 40 ha. If so the farms could also provide higher wages and take higher costs for land than then. A still heavier mechanization without any contracting work demanded very large farms.The accessibility of the farm building and the field sizes had an especially important effect on the evolution possibilities of the farms. In establishing improvement plans for this area, these factors should be taken more into account than any increase in the number of public roads.</p
