However, the functions of many cell wall synthesis genes, and the relationships among and the functions of cell wall components remain obscure. To better understand the patterns of cell wall accumulation and identify genes that act in grass (...) cell wall biosynthesis, we characterized 30 samples from aerial organs of rice at 10 developmental time points, 3-100 d post-germination. Within these samples, we measured 15 cell wall chemical components, enzymatic digestibility and 18 cell wall polysaccharide epitopes/ligands. We also used quantitative reverse transcription-PCR to measure expression of 50 glycosyltransferases, 15 acyltransferases and eight phenylpropanoid genes, many of which had previously been identified as being highly expressed in rice. Most cell wall components vary significantly during development, and correlations among them support current understanding of cell walls. We identified 92 significant correlations between cell wall components and gene expression and establish nine strong hypotheses for genes that synthesize xylans, mixed linkage glucan and pectin components. This work provides an extensive analysis of cell wall composition throughout rice development, identifies genes likely to synthesize grass cell walls, and provides a framework for development of genetically improved grasses for use in lignocellulosic biofuel production and agriculture.

Aim: The primary aim of the study was to evaluate two different methods of communicating information on cardiopulmonary resuscitation to patients admitted to general medical and elderly care wards. The information was either in the form of a detailed information leaflet or a summary document . The study examined the willingness of patients in seeking detailed information on cardiopulmonary issues.Setting: The study was conducted over three months on a general medical ward and an acute elderly care ward in two district (...) general hospitals.Methods: A detailed information leaflet on CPR was provided to the nursing staff on the wards. An A4 summary document summarising the CPR decision making process and basic information on cardiopulmonary issues was placed in a folder at the foot of each bed on the elderly care ward. On the general medical ward it was displayed prominently over the head of all beds.Results: Out of the 274 patients admitted to the general medical ward only two requests were received for the detailed information leaflet. On the elderly care ward there were 182 admissions but no patients or their relatives requested the leaflet.Conclusions: Availability of basic information on cardiopulmonary resuscitation to all patients is practical and does not lead to unnecessary distress or offence to patients or their carers. It makes the decision making process more transparent. Detailed information leaflets are of value for a minority of hospitalised patients. (shrink)

This article examines the business practices of Jamsetji Nusserwanji Tata, the founder the Tata group of business in India in the 19th century, from the perspective of stakeholder welfare. Jamsetji Nusserwanji Tata was concerned about the welfare of all major stakeholder constituents. His business practices promoted the welfare of employees, customers, society, owners, competitors, environment and other stakeholders. He implemented several measures even before law mandated them thus acting as a forerunner in promoting stakeholder welfare. His business plans became the (...) foundation for an economically strong India. This article, after an initial overview of the stakeholder framework, describes the business practices of Jamsetji Nusserwanji Tata with regard to major stakeholder constituents. Relevant research findings regarding each stakeholder constituent studied have been cited to show that the practices of Jamsetji Nusserwanji Tata have relevance to business even today. (shrink)

The complex societal challenges of the twenty-first Century require scientific researchers and academically educated professionals capable of conducting scientific research in complex problem contexts. Our central claim is that educational approaches inspired by a traditional empiricist epistemology insufficiently foster the required deep conceptual understanding and higher-order thinking skills necessary for epistemic tasks in scientific research. Conversely, we argue that constructivist epistemologies provide better guidance to educational approaches to promote research skills. We also argue that teachers adopting a constructivist learning theory (...) do not necessarily embrace a constructivist epistemology. On the contrary, in educational practice, novel educational approaches that adopt constructivist learning theories often maintain traditional empiricist epistemologies. Philosophers of science can help develop educational designs focused on learning to conduct scientific research, combining constructivist learning theory with constructivist epistemology. We illustrate this by an example from a bachelor’s program in Biomedical Engineering, where we introduce conceptual models and modeling as an alternative to the traditional focus on hypothesis testing in conducting scientific research. This educational approach includes the so-called B&K method for constructing scientific models to scaffold teaching and learning conceptual modeling. (shrink)
