Studies of Effectiveness of Commercial Home Treatment Systems
Eleven home water systems were tested representing six different types of filtering systems. Tests were made for Sulfates, Nitrates, Phosphate, Iron and Escherichia coli and Enterobacter aerogenes before and after passing through a home treatment system. All of the systems removed iron adequately but had little effect on the removal of nitrates, phosphates, sulfates or control of pH. Since none of the ground waters was contaminated by coli- forms, nothing was established regarding the effectiveness of bacterial removal by these systems

A neo-Kaldorian approach to structural economic dynamics
Although the structural economic dynamic approach provides a simultaneous consideration of demand and supply sides of economic growth, it does not fully take into account the possible role played by demand in the generation of technical progress. From a neo-Kaldorian perspective, this paper seeks to establish the concepts of demand and productivity regimes in an open version of the pure labour Pasinettian model. In order to derive the demand regime, a disaggregated version of the static Harrod foreign multiplier is derived, while the productivity regime is built in terms of disaggregated Kaldor–Verdoorn laws. The upshot is a multi-sectoral growth model of structural change and cumulative causation, in which an open version of the Pasinettian model to foreign trade may be obtained as a particular case. Furthermore, we show that the evolution of demand patterns, while being affected by differential rates of productivity growth in different sectors of the economy, also play an important role in establishing the pace of technical progress
A multi-sectoral approach to the Harrod foreign trade multiplier
With this inquiry, we seek to develop a multi-sectoral version of the static Harrod foreign trade multiplier, by showing that it can be derived from an extended version of the Pasinettian model of structural change and international trade. This new version highlights the connections between the balance-of-payments and levels of employment and production. It is also shown that from this disaggregated version of the Harrod foreign multiplier we can derive an aggregate version of the multiplier. By following this approach we go a step further in establishing the connections between the Structural Economic Dynamic and Balance-of-Payments Constrained Growth approaches
How can we best assess the quality of life of people with dementia? The Bath Assessment of Subjective Quality of Life in Dementia (BASQID)
Purpose of the Study - The study aim was to develop a measure of self-reported QoL for people with mild to moderate dementia based on their views - the Bath Assessment of Subjective Quality of Life in Dementia (BASQID). Design and Methods - The measure was developed through multiple stages. Two field tests of the measure (n=60 & n=150) enrolled people with dementia from a memory clinic and the data were used to analyse the psychometric properties of the scale. Nested within this was a longitudinal investigation of 36 Alzheimer’s disease patients prescribed with acetylcholinesterase inhibitors. Results - The BASQID contains 14 items assessing a range of QoL issues. Results show that the BASQID satisfies the criteria of a valid, reliable, and acceptable assessment of subjective QoL. Scores were responsive to changes in QoL, over 3-months. Low association between the BASQID and Mini Mental State Examination indicates that cognitive function may influence QoL, but is an indirect measure of the QoL experienced during dementia. Implications – The BASQID provides a means of better understanding the experiences, perceptions, and beliefs of people with dementia. It does this through acknowledgement of the many influences on QoL, over and above health status. The BASQID can be used alongside objective assessments of dementia to provide a complete appraisal of a person’s QoL
The Role of the Earth in Merleau-Ponty’s Archaeological Phenomenology
This paper argues that the concept of the Earth plays a pivotal role in Merleau-Ponty’s thinking in two ways. First, the concept assumes a special importance in terms of Merleau-Ponty’s relation to Husserl via the fragment known as “The Earth Does Not Move.” Two, from this fragment, the Earth marks a key theme around which Merleau-Ponty’s late philosophy revolves. In particular, it is with the concept of the Earth that Merleau-Ponty will develop his archaeologically oriented phenomenology. To defend this claim, the paper unfolds in three stages. First, I provide a preliminary reading of Husserl’s fragment, focusing in particular on the co-constitution of body and Earth. Two, I turn to Merleau-Ponty’s interpretations of this fragment, especially in the lectures on nature and then in the later lectures on Husserl. From these varying interpretations, the germs of Merleau-Ponty’s archaeological phenomenology are conceived. Accordingly, in the final part of the paper, I claim that Merleau-Ponty’s account of the Earth is Husserlian insofar as it reinforces the primordial “ground (sol) of experience” but at the same time marks a departure from Husserl insofar as the Earth registers a brute or wild layer that resists phenomenology
