The author outlines the procedures for paper lithography and suggests it as a worthwhile project for all grade levels. This article is one of several in this issue on graphic arts projects. (SJL)

Promoting social mobility seems to be simple common sense. However, the solutions proposed in the UK under successive governments reflect a problematic individualism that is not about helping all of the poorest children, but about encouraging the poor to become as ruthless and competitive as the middle and upper classes. This article shows how the…

This paper organizes and analyses over 500 geoscience misconceptions relating to earthquakes, earth structure, geologic resources, glaciers, historical geology, karst (limestone terrains), plate tectonics, rivers, rocks and minerals, soils, volcanoes, and weathering and erosion. Journal and reliable web resources were reviewed to discover (1) the…

A laboratory experiment is described to determine the primary current distribution in parallel-plate electrochemical reactors. The electrolyte is simulated by conductive paper and the electrodes are segmented to measure the current distribution. Experiments are reported with the electrolyte confined to the interelectrode gap, where the current…

Man cannot naturally be detached from his environment. From time to time, changes in climate and environmental conditions occur as a result of natural and human factors. Obviously, the natural factors are almost beyond human control. But, the human factors are to a very large extent under human control. Thus, this paper tried to discover natural…

A book is a treasure that can hold fascination and wonder within and capture our attention with exterior beauty as well. With this in mind, the author had her students explore the rare book covers of the Middle Ages, when books were handwritten by monks on handmade paper. They created their own large-format books (12 x 13" or 30.5 x 33 cm)…

Many of us have grabbed two pieces of aluminum foil and a paper towel, quickly sandwiched them together, and exclaimed in lecture, "Look! It's easy to make a capacitor!" Then we move on from there, calculating things such as capacitances with various dielectrics or plate sizes, the capacitance of capacitor networks, RC circuits,…

Chilling is a cost-effective and safe method of immobilising flies in "Drosophila" experiments. However, should condensation form on the plate, it would be fatal to the flies. Here we describe a modified cooling method using reusable commercial ice pack(s) (ca. 400 ml, 2-3 cm tall) rather than crushed ice. The ice pack is covered with a…

Purpose: Research vitality addresses the perseverance that faculty members in the organization sciences experience in maintaining their research quantity and quality over an extended period of time. The purpose of this paper is to offer a theoretical model of research vitality. Design/methodology/approach: The authors propose a model consisting of…

In this paper we address a common misconception concerning the thermal behaviour of matter, namely that the front surface of a very thin plate, uniformly illuminated by a constant light beam, reaches a higher temperature than the front surface of a very thick slab made out of the same material. We present analytical solutions for the temperature…

Phenomenograhy, as an approach to educational research, began appearing in publications early in the 1980s with the predominant form of data drawn from semi-structured interviews. As a qualitative approach, it is used to describe the variations in people's experiences through their own discourse and for analyzing meaning that people ascribe to…

This paper aims to highlight the issues associated with the implementation of education reform policies relating to "future schools" in a small state in the Middle East and North Africa region. The study points to the consistency with which global corporations and the supranational organisations, such as UNESCO and the World Bank,…

Purpose: The purpose of this paper is to contribute to the literature on the many dimensions of the principal's positionality by using a unique research approach to link the experiences of the policy implementing principal to embodiment. Design/methodology/approach: The researchers employed a form of critical policy analysis that utilized…

The method for extracting and separating hydrophobic photosynthetic pigments proposed by Katayama "et al." ("Japanese Journal of Phycology," 42, 71-77, 1994) has been improved to introduce it to student laboratories at the senior high school level. Silica gel powder was used for removing water from fresh materials prior to…

We describe a simple case of non-localized interference produced with a glass plate and a laser beam focused on it. The proposed setup for observing interference is compact when semiconductor lasers are employed, and it is well suited for demonstration and comparison of interference in reflected and transmitted light in a large lecture-room. This…
