Lessons from new experiences in extension in West Africa: Management advice for family farms and farmers' governance

The emergence of Management Advice for Family Farms in West Africa is closely related to the increased integration of farmers into an open market economy. This is creating a strong demand from farmers for advisory support services, focusing on management of the farm. With the gradual withdrawal of the State from extension services delivery, a stimulating context exists for reviewing approaches and systems of support delivery facilities for producers. In response to these developments, several experiments based on the concepts of Management Advice for Family Farms are going on in West Africa. Beyond a variety of objectives and implementation procedures analysed in this paper, common features and a considerable degree of consensus on concepts emerge. Strengthening the producers' capacity for assessment, decision-making, and management of their farms is a common objective. Differences exist between procedures for delivery of advice, methods, tools used, and emphasis put on different aspects of management. All experiments stress the importance of training, enhancing group dynamics, and individual learning. They are all farmer and farm family targeted. Expression of farmers' objectives, needs, and demands is essential. Advice is based on data gathering and assessment by the farmers themselves. From mere technicians, extension workers become advisors and facilitators. In all cases, Farmers' Organisations are involved in governing the delivery services, though at different degrees. In several cases priority is given towards strengthening farmers' capacity in the management of delivery at both local and global levels. Significant improvements in farm performances have been reported. Cost sharing is generally accepted, but insufficient to cover all costs. However, to reach sustainability for farmers' driven and governed advice delivery services, innovative agricultural policies, and public finance are needed.     

凉州熏醋大曲中细菌区系研究

研究了凉州熏醋传统酿造大曲中细菌区系,对大曲中的细菌总数、醋酸菌、乳酸菌及耐热菌进行计数、分离纯化和鉴定,通过显微镜镜检、革兰氏染色、接触酶反应、需氧型、产酸产气、发酵性等特性测定,对分离的菌株进行了具体菌属鉴定.结果表明,大曲表面与大曲中心细菌区系差异明显;大曲中共分离到5株醋酸菌、8株乳酸菌和4株耐热菌;醋酸菌分属为醋杆菌属和葡糖杆菌属;乳酸菌分属为糖球菌属、链球菌属、魏斯氏菌属、乳球菌属和索丝菌属;耐热菌分属为微球菌属和芽孢杆菌属.     

彰显地方办学特色 提高师范办学优势

近年来,作为一个在中小型城市发展的地方性师范院校,特色办学的优势越来越明显。把建设地方性、多科性、开放性新型师范院校作为我校发展的战略目标,既可以不断提高人才质量的培养,优化学科、专业队伍结构的建设,推进教育教学改革和人才培养模式,实现学校核心竞争力、综合实力和社会影响力的同步提升,又能扬长避短,在激烈的搏弈中探索到发展与前进的动力和方向。     

紫外诱变酿酒酵母筛选耐高温菌株

以实验室保存的酿酒酵母为初始菌株,采用紫外分光光度法测定菌株浓度,绘制出菌株生长曲线,由此确定出最佳诱变菌龄为3～10h,在此期间利用紫外线对菌株进行诱变,筛选出一株适于在高温下发酵的菌株,紫外线诱变条件为：紫外灯功率10w,照射距离30cm,照射时间3min。此菌株在37℃下培养72h,其成熟发酵醪酒精产率为3．837％。

Evaluating the NASA small business innovation research program: preliminary evidence of a trade-off between commercialization and basic research

In 1982, the Small Business Innovation Development Act established the small business innovation research (SBIR) program. This program reserves a percentage of federal agencies’ extramural R&D budgets for research projects conducted by small businesses. When this Act was reauthorized in 1992, the selection criteria for funding dramatically increased the likelihood of funding for projects that promised to lead to commercial success. Using data from a survey of the SBIR program award recipients at NASA Langley Research Center, we address three questions about this change: (i) was there a shift to projects with more commercial potential? (ii) did these projects experience higher rates of commercial success? and (iii) was there a reduction in basic research accompanying the increased commercial success? Our analysis suggests, the answer to all three of these questions is ‘yes’.
