A functional analysis of glass from an officer's mess, Malta

The nineteenth century witnessed an explosion in the use of glass as a material from which containers and tableware were made. No longer confined to the packaging and consuming of liquids, a wealth of products were packaged in branded and patented containers. This article presents an initial analysis of glass recovered from archaeological investigations at the Inquisitor's Palace, Vittoriosa, which in the second half of the nineteenth century was an army mess house and officers' quarters. Focusing on function, key groups of glass finds are described. Where possible, brands and manufacturers are contextualised through complementary documentary sources, providing a broader focus and relevance to the material. From baby food jars to hard liquor bottles, the glass finds present a picture of daily life that stretches beyond typical views of military life and highlights the importance of glass finds to understanding post-medieval contexts.peer-reviewe

Maltese ceramics and imperial foodways: an exploration of nineteenth-century red wares

The archaeological study of recent periods in Malta is in its infancy. Despite the high potential for an historical archaeology of Malta contributing to broader issues such as an understanding of Mediterranean trade and colonialism, as well as the cultural history of Malta, the archaeological resource has remained under-explored. The aim of this article is to address the situation and offer an initial classification and interpretation of local and imported red earthenware ceramics. It will demonstrate the need for such work in relation to answering questions relating to local production, international trade, and foodways

Selecting teachers for tenure in the East Whittier School District

Boards of education throughout the country are cognizant of the shortage of well qualified elementary school teachers. There has been considerable competition among school boards for the limited supply of teachers, so much so that teachers have been tempted to move from place to place, standards of teaching proficiency have been lowered, and little relief of the general shortage has been achieved. When a school system has succeeded in filling all teacher vacancies, too frequently complacency reigns until the beginning of another school year. When the quantitative shortage of teachers is compounded by a recognition of the persistent qualitative shortage, the situation becomes critical, and its solution is a challenge to the best professional and lay minds in the country. Boards of education and public school administrators have a major responsibility, one that they dare not ignore. Their chief business is to employ competent teachers and to create a favorable situation in which these capable teachers can work

Economics of Pollution Trading for SO2 and NOx

For years economists have urged policymakers to use market-based approaches such as cap-and-trade programs or emission taxes to control pollution. The SO2 allowance market created by Title IV of the 1990 U.S. Clean Air Act Amendments represents the first real test of the wisdom of economists’ advice. Subsequent urban and regional applications of NOx emission allowance trading took shape in the 1990s in the United States, culminating in a second large experiment in emission trading in the eastern United States that began in 2003. This paper provides an overview of the economic rationale for emission trading and a description of the major U.S. programs for sulfur dioxide (SO2) and nitrogen oxides (NOx). We evaluate these programs along measures of performance including cost savings, environmental integrity, and incentives for technological innovation. We offer lessons for the design of future programs including, most importantly, those reducing carbon dioxide.sulfur dioxide, nitrogen oxides, emission trading, power plants, air pollution

The FX/90: A proposal in response to a low Reynolds Number station keeping mission

The FX/90 is a remotely piloted vehicle designed to fly at Reynolds numbers below 2 x 10 to the 5th power. Several applications exist for this type of flight, such as low altitude flight of very small aircraft. The design presented here allows investigation into the unique problems involved in low Reynolds number flight, which will, in turn, further understanding of this flight regime. The aircraft will operate in a steady flight environment, free from significant atmospheric turbulence and weather effects. The F-90 has a 39 in. fuselage which is constructed of balsa and plywood. The landing gear for the aircraft is a detachable carriage on which the aircraft rests. The aerodynamic planform is a rectangular wing (no taper or sweep) with a chord of 9 in., a wingspan of 72 in., and is constructed entirely out of styrofoam. The propulsion system is a puller configuration mounted on the front of the fuselage. It consists of an Astro 05 engine and a 10-6 two bladed propeller. Control of the aircraft is accomplished through the use of two movable control surfaces: elevators for pitch control, and a rudder for yaw control. The aircraft is soundly constructed, highly maneuverable, and adequately powered. Furthermore, the investigation into alternative technologies, most notably the styrofoam wing and the detachable landing gear, holds promise to improve the performance of the aircraft
