title: Arcs of supply chain integration

authors: Childerhouse, Paul

subjects: supply chain integration

abstract: Integration is posited by many authors as a supply chain utopia. Indeed, it is claimed as being synonymous with supply chain management excellence. The primary aim of this research is to verify the link between supply chain integration and competitive performance. Detailed information collected via an 8-year international field study of 50 products and their associated supply chains subjected to an extensive statistical analysis provides rigorous insight into supply chain integration in practice. The breadth of supply chain integration significantly correlates with increased performance, yet in practice, the majority of supply chains are not well integrated. However, most supply chains seem to follow a popular route when seeking to enable seamless operations. This starts with enhanced internal effectiveness followed by upstream streamlining and then finally downstream integration. If practitioners are still struggling with supply chain integration, this research confirms that they are not unique in their predicament. Indifferent practice is indeed the norm. Fortunately, practitioners can follow the popular route established herein when seeking to improve integrative capability.

title: A comparative study of the effects of a concept mapping enhanced laboratory experience on Turkish high school students’ understanding of acid-base chemistry

authors: Özmen, Haluk

subjects: acids and bases

abstract: The research reported here consists of the introduction of an intervention based on a series of laboratory activities combined with concept mapping. The purpose of this intervention was to enhance student understanding of acid-base chemistry for tenth grade students’ from two classes in a Turkish high school. An additional aim was to enhance student attitude toward chemistry. In the research design, two cohorts of students were compared; those from the intervention group (N = 31) and a second group (N = 28) who were taught in a more traditional manner. Student understanding of acid-base chemistry was evaluated with a pretest/posttest research design using a purpose-designed instrument, the Concept Achievement Test (CAT) consisting of 25 items, 15 multiple choice and ten multiple choice with explanation. Alternative conceptions identified in the pretest were incorporated into the intervention, which thereby sought to move students toward views more in accord with scientific views for the concepts. Statistical tests indicate the instrument is reliable (with an alpha reliability of 0.81) and the analysis of the findings revealed statistically significant differences between the intervention and traditional groups with respect to conceptual understanding. Examination of student explanations and analyses of semi-structured interviews conducted with selected students suggest that the main influence was the laboratory activities. Analysis of the findings in the context of relevant literature that concept mapping in conjunction with laboratory activities is more enjoyable, helps student link concepts, and reduces their alternative conceptions.

title: Niupepa: A historical newspaper collection

authors: Apperley, Mark

abstract: Niupepa is a collection of 42 newspaper titles published in New Zealand from 1842-1933, comprising a total of 21,000 pages in 1,750 issues. This collection forms a unique historical record of the language of the indigenous Mãori people, the evolution of the written form of this language, and of events and developments during the formative colonial history of our country. Using the Greenstone software from the New Zealand Digital Library this collection is now publicly available with full-text search capability.
