用户感知移动图书馆服务质量评价的犹豫模糊Kano-Taguchi方法

[目的/意义]大数据时代下,移动图书馆对用户阅读方式和获取知识具有重要作用。在用户感知移动图书馆服务质量需求由分散转向关联,服务质量评价过程由精确转向模糊多元的情形下,文章提出了一种模糊Kano模型与犹豫模糊Taguchi方法为核心的综合评价方法。[方法/过程]首先,根据用户与决策者的偏好信息以模糊Kano修正指标重要度,分析用户的直接需求。其次,根据评价过程中的不确定性及指标的关联冲突,提出一种犹豫模糊Kano-Taguchi方法,该方法通过对主客观综合重要度的分析体现了用户与决策者对移动图书馆的偏好程度。最后,以五所云南高校为例进行算例分析,且通过对比分析验证本研究方法的科学性与合理性。[结果/结论]研究表明,文章提出的方法不仅简便明了,而且客观充足。

切花月季组织培养试管苗移栽基质及其相关研究

本研究对切花月季组织培养试管苗移栽过程中移栽基质、移栽培养液的选择以及化学方法控制污染等几个因子进行了研究,结果表明:关于移栽基质对试管苗移栽后苗情的影响,在12种移栽基质中,以蛭石基质的栽培效果最好,所有含泥碳的基质的栽培效果都不好;关于杀菌剂处理移栽基质控制杂菌污染的试验表明,用杀菌剂持续处理移栽基质控制杂菌污染比基质一次性灭菌的效果好;关于不同移栽培养液及施用方式对移栽后苗情的影响的试验表明,先用自来水培养十天后,再用的1/2MS培养液培养,是较为理想的培养方法.     

Teachers' Perceptions of Factors Affecting Their Adoption and Acceptance of Mobile Technology in K-12 Settings

Factors influencing the adoption and acceptance of tablets as a mobile technology were explored one year after their integration in middle schools in Palestine. Semi-structured interviews were conducted with 15 teachers. The participants held a variety of attitudes toward accepting mobile technologies in their instruction. The findings revealed that teachers' attitudes are an important factor in accepting or rejecting tablet use in classrooms. Many factors influenced teachers' attitudes such as technical support, instructional assistance, and infrastructure. A teacher's prior experience with tablets was also important for integrating technology into the classroom.

由介质击穿强度认识两个静电问题

导体带电意味着电子的得失，带电量的多少将受到介质击穿强度的限制，由于这种绝缘性能的限制，导体带电时导体的质量不会因为有限数目的电子得失而明显变化；导体表面只有很小比例的中性原子涉及电子的得失，不必担心电荷分布“由表及里”。     

Local language a medium of instruction: challenges and way forward

The paper reports on a participatory action research study conducted in six rural primary schools in Uganda in 2013 to establish why children taught in the local language had difficulties in reading and writing. Findings through interviews, focus group discussions, reviews of exercise books and lesson observations indicated that though it was easier for pupils to learn the concepts in the local language; challenges ranging from poor translation, inadequate teachers’ language proficiency, lack of instructional materials, high pupils’ enrolment, lack of administrative support and teacher-centred approach of teaching, affected pupils’ learning to read and write. Participants recommended adopting the child-centred pedagogy, incorporating instructional materials, conducting continuous assessment and recording pupils’ competencies attained in reading and writing. Teachers need to engage more in Participatory action research in order to reflect on their practices and pupils’ learning, and collaboratively decide what works best and what needs improvement in their classrooms.
