Reuse of waste frying oil for production of rhamnolipids using Pseudomonas aeruginosa zju.u1M

In this work,rhamnolipid production was investigated using waste frying oil as the sole carbon source. By culture in shaking flasks,a naturally isolated strain synthesized rhamnolipid at concentration of 12.47 g/L and its mutant after treatment by UV light increased this productivity to 24.61 g/L. Fermentation was also conducted in a 50 L bioreactor and the productivity reached over 20 g/L. Hence,with a stable and high productive mutant strain,it could be feasible to reuse waste frying oil for rhamnolipid production on industrial scale.

Teachers’ perceptions of the benefits,limitations, and areas for improvement of the funds of knowledge approach. A qualitative study

Within the broad range of literature on the funds of knowledge approach, several positive impacts have been documented. In particular, participating teachers have reported meaningful changes in their relationships with students’ families as a consequence of the home visits. However, few studies have assessed the limitations of the approach, or areas for improvement. Hence, the aim of the study described here was to identify what teachers felt were the strengths and the weaknesses of the approach and to record their proposals for improvements. The teachers involved had participated in all phases of the program: from the initial training to the creation and implementation of educational activities based on the funds of knowledge identified from home visits. The positive aspects identified include improved family–school relationships; a better understanding of student behavior and attitudes, and the support of their colleagues and the University staff in the context of the study group created.     

Disturbing Reading: J.M. Coetzee's ‘The Problem of Evil’

A literary representation can give us grief. J.M. Coetzee's ‘The Problem of Evil’ follows the crisis of reading of his main character Elizabeth Costello as she struggles to comprehend discursive images of evil. Costello's trouble with reading is not attributed to a cognitive deficiency in her ability to read the text but to a psychical disturbance she experiences while reading. Thinking through our ‘disturbances’ while and after reading gives readers an opportunity to rethink reading as affected by the thoughts and words of others.

A Review of: “Organizing Schools for Improvement: Lessons from Chicago. Anthony S. Bryk,Penny Bender Sebring,Elaine Allensworth,Stuart Luppescu,and John Q. Easton.”

This article summarizes the results of a study of state and local practices related to the implementation of Title I of the Improving America's Schools Act (IASA; 1994). In translating policy to practice, state and local practitioners articulated how they approached the provisions of IASA: the expectation that all children will meet challenging state standards, flexibility with accountability, targeting funds, family and community partnerships, and support system roles and infrastructure. This snapshot of reform in progress shows that multiple chains of events at the national and state levels influenced the implementation of the law and that more time and support are needed to produce the impact intended in the Title I reauthorization.     

Implications of R.S. Peters’ notion of ‘cognitive perspective’ for science education

This paper discusses R.S. Peters’ notion of ‘cognitive perspective’, which, through careful reading, can be interpreted as a wider perspective resulting from an awareness of the relationships of one’s knowledge and understanding to one’s own life. This interpretation makes cognitive perspective a holistic notion akin to that of worldview, and also points to the possibility for students to experience a change of outlook on the world, as a result of learning science. Given the ongoing debate regarding the notion scientific literacy and the problems associated with it, the development of cognitive perspective can be considered the primary goal of school science education, as it provides an alternative way to think about what it means for a student to be educated in science. Such a goal, in turn, points to the importance of teaching for the (practical and emotional) significance of scientific facts and ideas, as awareness of such significance does not necessarily follow the acquisition of content knowledge and the application of the latter in everyday contexts. The paper also attempts to clarify the notion of utility of scientific knowledge, as an understanding of such notion is crucilal for understanding the implications of the development of cogintive perspective for school science education.
