“I’ve Tried and I’ve Died This Year”: First-Year Teachers Reflect on Literacy Reform

This article describes the challenges associated with outcomes-based education reform as experienced by two novice elementary teachers. Interviews with the teachers provide insights into the tensions between their teaching beliefs and the practices employed in their local contexts. Specifically, pressures to both focus on standardized measures of student achievement and to conform to the social norms of the schools are explored. The authors advocate for the need for situated discussions about these tensions during the first year of teaching and recognition of the complexity of teaching and learning by all stakeholders.     

Civic rhythms in an informal,media-rich learning program

Increasingly, adult mentors in informal, media-rich settings, like libraries and museums, seek to integrate both learning and civic engagement opportunities for youth into designed programming. This article illustrates how youth open and sustain opportunities for civic engagement over the course of a six-month, youth-driven program – Metro: Building Blocks (MBB) – housed within a digital media learning lab in an urban public library. Analysis develops the concept of civic rhythms as a means to feel out the social and affective contours of civic engagement that emerge in MBB. To better understand the civic rhythms of MBB, analysis focuses specifically on three rhythmic elements: pulsation, reciprocation, and oscillation. The article concludes suggesting that future research develop principles for designing-in-time that assist researchers and mentors in attuning to the youth-driven rhythms that sustain informal, media-rich programs.     

Knowledge sharing in a multi-cultural setting: a case study

Organizational culture has been shown to influence the success of knowledge management practices. Hofstede's theory specifies that organizational culture is not independent of national culture. A case study of an international subsidiary was conducted to explore the extent to which knowledge sharing is dependent on national culture. Results indicate that language differences can create knowledge blocks, and cross-cultural differences can explain the direction of knowledge flows.     

Humphry Davy: science and social mobility

Humphry Davy (1778–1829) was one of the first professional scientists, earning his living and rising spectacularly from an impoverished upbringing in Cornwall to be President of the Royal Society and a baronet. He owed his rise to patronage as well as to his range of abilities: as a lecturer, as a chemical theorist and as a very early applied scientist. But his exalted position brought him little happiness, for he could not satisfy all the hopes put upon him as the successor to Sir Joseph Banks. Admired rather than loved, he became unpopular and was seen as haughty. In his last two years, spent wandering lonely and sickly in Italy and the Alps, he sought to make sense of his life, writing dialogues as his bequest to the new generation.     

External quality assessment for the RIA of thyroid related hormones: Second phase

An external quality assessment was conducted to assess the performance of various laboratories for RIA of thhyroid related hormones in two phases. In the first phase thirty five laboratories participated. At the end of first phase a meeting cum workshop was organised to discuss the results of first phase, difficultires faced by the participants and pinpoint the short oming. A second phase was then initiated with an objective of improvement in the performance, if any, where twelve samples from four pools were distributed to twenty four laboratories who participated for the second phase. The overall return of the results increased significantly from 71.8% (1586/2208) for the first phase to 92.4% (732/792) for the second phase. The inter laboratory %CV for T₃, T₄ and TSH were lower during the second phase (30.6%, 19.0% and 31.6% respectively) as compared to those observed during first phase (36.3%, 22.7% and 52.8% respectively). Similarly, there was an improvement in reproducibility of ALTM as %CV for T₃, T₄ and TSH decreased from 6.0%, 9.8% and 13.4% respectively to 4.5%, 4.6% and 8.5% respectively. The individual performances of the participating laboratories viz. bias, variability of bias and imprecision also showed a trend towards improvement as percent laboratories having desirable or acceptable results for T₃, T₄ and TSH increased from 10.7%, 60.7% and 0.0% respectively to 20.8%, 66.7% and 22.2% respectively. External quality assessment thus appears to be beneficial in assessing the performane of a laboratory in comfparison with other laboratories and indeed helps in improving the performance.     

Diurnal variation in serum glucose,pyruvate, lactate and lactate dehydrogenase levels under different environmental temperatures

Circadian rhythm of serum glucose, pyruvate, lactate and lactate dehydrogenase (LDH) was studied in normal healthy young volunteers at the onset (I Group, 7 cases) and peak (II Group, 8 cases) of winters in India with highly varied temperature. There was a significant difference, in the circadian rhythm of glucose, pyruvate and lactate dehydrogenase (LDH) of the two groups. A clockwise shift was observed in acrophase except in serum lactate, which is related to the energy demand in association with time qualified changes in diurnal activity of the individuals and change in photoperiod.
