Business Models for Content Delivery: An Empirical Analysis of the Newspaper and Magazine Industry

Although there have been efforts to define, describe, and classify business models, current literature does not provide a structured method of comparing business models between companies within or between industries. This article outlines a conceptual business model and proposes 5 components that a business model for content delivery should include: the product, the consumer, the revenue, the price, and the delivery. By using the newspaper and magazine industry as an example, we empirically test the impact of these 5 components on profit. Furthermore, we address 2 key issues content providers are confronted with when selling digital content: First, how much of the digital content is available free or at cost, and second, is the digital product as complementary or a substitute to the physical product. Finally, we assess the risk of cannibalizing the physical product with the digital one by a multiple regression analysis.     

Data Rules: How Mapping Technology Drives Better Customer Service

Is your library market-driven, product-driven or customer-driven? New internet-based data and tools are now available for public libraries that enable you to be customer-driven—for your own unique service area. This article shows how three library systems are using these tools—focused on market segmentation data and geographic information system (GIS) technology—to deliver more relevant customer services. Each solution described in the article was developed in close collaboration between CIVICTechnologies and the library, involving research to understand the library's objectives and desired outcomes, and using the data needed to meet each library's unique challenge.     

Use of Polarised Light Microscopy to Improve Conservation of Parchment

ABSTRACT

The preservation state of parchment primarily depends on the structure of the collagen fibre network, which in turn is responsible for optical anisotropy, i.e. birefringence. Polarised light microscopy can therefore be used as a non-invasive technique that allows recording of birefringence distribution in the parchment, which directly relates to stress–strain distribution. Using samples from diverse sources (commercial parchment, parchment used by restorers for book binding, and parchment fabricated for the purpose of this study), we assessed the capability of polarised light microscopy for various diagnostics. We performed, for instance, identification of gelatinised regions, layered or ?brous regions in parchment cross section, qualitative analysis of parchment fat content (lipids), observation of stress-induced patterns resulting from tensile tests, and observation of water diffusion. These proof-of-principle experiments extend the capability of polarised light microscopy far beyond its common use and open the path to its deployment in conservation studies.

Modelling Molecular Mechanisms: A Framework of Scientific Reasoning to Construct Molecular-Level Explanations for Cellular Behaviour

Although molecular-level details are part of the upper-secondary biology curriculum in most countries, many studies report that students fail to connect molecular knowledge to phenomena at the level of cells, organs and organisms. Recent studies suggest that students lack a framework to reason about complex systems to make this connection. In this paper, we present a framework that could help students to reason back and forth between cells and molecules. It represents both the general type of explanation in molecular biology and the research strategies scientists use to find these explanations. We base this framework on recent work in the philosophy of science that characterizes explanations in molecular biology as mechanistic explanations. Mechanistic explanations describe a phenomenon in terms of the entities involved, the activities displayed and the way these entities and activities are organized. We conclude that to describe cellular phenomena scientists use entities and activities at multiple levels between cells and molecules. In molecular biological research, scientists use heuristics based on these intermediate levels to construct mechanistic explanations. They subdivide a cellular activity into hypothetical lower-level activities (top-down approaches) and they predict and test the organization of macromolecules into functional modules that play a role in higher-level activities (bottom-up approaches). We suggest including molecular mechanistic reasoning in biology education and we identify criteria for designing such education. Education using molecular mechanistic reasoning can build on common intuitive reasoning about mechanisms. The heuristics that scientists use can help students to apply this intuitive notion to the levels in between molecules and cells.     

Teachers’ beliefs about improving transfer of algebraic skills from mathematics into physics in senior pre-university education

ABSTRACT

Students in senior pre-university education encounter difficulties in the application of mathematics into physics. This paper presents the outcome of an explorative qualitative study of teachers’ beliefs about improving the transfer of algebraic skills from mathematics into physics. We interviewed 10 mathematics and 10 physics teachers using a semi-structured questionnaire that was based on an algebraic transfer problem. Almost all teachers acknowledged this transfer problem and considered it to be important. We found a continuum of teachers’ beliefs about aspects influencing transfer, including beliefs on improving this transfer. Together with identified improvement aspects about coherent mathematics education, these may help reduce physics teachers’ frustrations who spend extra time on re-teaching mathematics. Teachers think that transfer does not happen, because students see both subjects as separate disciplines. Contrary to most physics teachers, most mathematics teachers do not feel the need to collaborate with physics teachers. We found two extreme, opposite beliefs about the transfer of algebraic skills into physics. An intermediate group believes that only an integrated approach can solve the transfer problem. Some of the teachers’ beliefs could be organised into a beliefs system. Further research could investigate to which extent such beliefs systems exist and which beliefs these contain.     

Tasks and trajectories in learning to teach

University‐based teacher‐education programmes in the USA confront mounting pressure to demonstrate that graduates will have a significant and positive impact on student achievement. Such pressure has forced teacher educators to wrestle with the question of what constitutes compelling evidence that teacher candidates will indeed have such an impact. This paper presents the deliberations and resulting investigation of a team of university faculty members seeking to account for preservice elementary‐school teachers’ learning and development. It offers a preliminary articulation of a trajectory of learning, and a critique of the tasks and the programmatic experiences from which this trajectory is constructed.     

Moving Toward the Quality of Life

The practice of the self-defense martial arts has much to offer physical education. In this paper we draw on Pierre Bourdieu's sociological theory of the Logic of Practice to present a case that when viewed as a social practice, these movement forms generate certain, specific, practically oriented schemes of dispositions or habitus in the practitioner. We then consider the potential value of using matia1 arts practice in physical education for their ability to offer a glimpse at genuinely alternative ways of relating to oneself and the world through the physical mediunm that would help to compliment and offset the overriding domninance of dualist understandings of the mind /body nexus that currently exists in Western physical education.     

Educating for Commitment: Insights from Postmodernity

Abstract

Secular pluralism in contemporary culture and current theological divisions within churches have important implications for Christian education. This paper addresses the question of how religious commitments can be made and convictions held outside of polarizing and exclusionary understandings of truth, and without the presence of uncontested doctrines. What habits, practices and dispositions should Christians cultivate in this context? It brings resources from postmodern theology and philosophy into conversation with the Anglican tradition, in order to propose ways that Christian education can foster faith commitment in the midst of pluralism and disagreement.
