EC77-865 Have It Your Way By Making A Will

Making a will is not the sad and gloomy picture painted by some people. Quite the contrary! A person who makes a will is creating his or her own blueprint for the future. A will, like life insurance, social security, or retirement plans, provides security and peace of mind. The person who has a will made can rest assured that property and loved ones will be taken care of precisely in the manner he or she desires. This publication presents basic information about wills, one of the most important documents a person can make or possess. This information can be useful both to those who have already made a will and those who have not.

HIV heterogeneity and proximity of homestead to roads in rural South Africa: an exploration using a geographical information system

OBJECTIVE To describe heterogeneity of HIV prevalence among pregnant women in Hlabisa health district, South Africa and to correlate this with proximity of homestead to roads. METHODS HIV prevalence measured through anonymous surveillance among pregnant women and stratified by local village clinic. Polygons were created around each clinic, assuming women attend the clinic nearest their home. A geographical information system (GIS) calculated the mean distance from homesteads in each clinic catchment to nearest primary (1 degrees) and to nearest primary or secondary (2 degrees) road. RESULTS We found marked HIV heterogeneity by clinic catchment (range 19-31% (P < 0.001). A polygon plot demonstrated lower HIV prevalence in catchments remote from 1 degrees roads. Mean distance from homesteads to nearest 1 degrees or 2 degrees road varied by clinic catchment from 1623 to 7569 m. The mean distance from homesteads to a 1 degrees or 2 degrees road for each clinic catchment was strongly correlated with HIV prevalence (r = 0.66; P = 0.002). CONCLUSIONS The substantial HIV heterogeneity in this district is closely correlated with proximity to a 1 degrees or 2 degrees road. GIS is a powerful tool to demonstrate and to start to analyse this observation. Further research is needed to better understand this relationship both at ecological and individual levels, and to develop interventions to reduce the spread of HIV infection.

Studies of solute self-association by sedimentation equilibrium: allowance for effects of thermodynamic non-ideality beyond the consequences of nearest-neighbor interactions

A sedimentation equilibrium study of a-chymotrypsin self-association in acetate-chloride buffer, pH 4.1 I 0.05, has been used to illustrate determination of a dimerization constant under conditions where thermodynamic non-ideality is manifested beyond the consequences of nearest-neighbor interactions. Because the expressions for the experimentally determinable interaction parameters comprise a mixture of equilibrium constant and excluded volume terms, the assignment of reasonable magnitudes to the relevant virial coefficients describing non-associative cluster formation is essential for the evaluation of a reliable estimate of the dimerization constant. Determination of these excluded volume parameters by numerical integration over the potential-of-mean-force is shown to be preferable to their calculation by approximate analytical solutions of the integral for this relatively small enzyme monomer with high net charge (+ 10) under conditions of low ionic strength (0.05 M).

Allowance for thermodynamic non-ideality in the characterization of protein self-association by frontal exclusion chromatography: hemoglobin revisited

This investigation re-examines theoretical aspects of the allowance for effects of thermodynamic non-ideality on the characterization of protein self-association by frontal exclusion chromatography, and thereby provides methods of analysis with greater thermodynamic rigor than those used previously. Their application is illustrated by reappraisal of published exclusion chromatography data for hemoglobin on the controlled-pore-glass matrix CPG-120. The equilibrium constant of 100/M that is obtained for dimerization of the (02 species by this means is also deduced from re-examination of published studies of concentrated hemoglobin solutions by osmotic pressure and sedimentation equilibrium methods.

Determinants of the price of allowance in the European Union emissions trading market

Teorian mukaan täydellisen kilpailun päästöoikeuskauppamarkkinoilla päästöoikeuden hinta muodostuu markkinoilla vallitsevan päästöjen vähentämisen rajakustannuksen perusteella. Euroopan päästökauppamarkkinoilla päästöjen vähentämisen kustannuksia nostavat suhteellisen lyhyet päästökauppajaksot ja epävarmuus järjestelmän jatkuvuudesta. Toisaalta päästökaupan osallistujien yhteenlaskettu päästöjen vähentämisen tarve lienee suhteellisen vähäinen ellei olematon ensimmäisellä päästökauppajaksolla. Euroopan päästökauppamarkkinoilla päästöjen vähentämisen tarve ja päästöjenvähentämisen kustannukset ovat osittain riippuvaisia muuttuvista tekijöistä. Päästöoikeuden hintaan voivat vaikuttaa päästökauppajakson aikana tapahtuva teollisuuden suhdannevaihtelu, polttoaineiden hintojen heilahtelut sekä säätilojen vaihtelu. Päästökaupan ensimmäisinä kuukausina päästöoikeuden hintakehityksellä on ollut yhteyksiä tekijöihin, joiden muutosten tulisikin vaikuttaa päästökauppamarkkinoiden tasapainoon. Näitä tekijöitä ovat esimerkiksi polttoainemarkkinoiden ja sähkömarkkinoiden hintakehitys sekä vaihtelut säätiloissa.

Argentina: Impacts of the child allowance programme on the labour-market behaviour of adults

In 2009 Argentina implemented the Universal Child Allowance for Social Protection (AUH), a cash transfer programme for households with children. Coverage provided by the contributory family allowance programme was extended to parents who are unemployed or who work in the informal sector (domestic workers, for example). This paper uses the difference-in-difference estimator and propensity score matching techniques to evaluate the short-term effects of the auh on adult labour participation and income generation. The results suggest that, during its first year of operation, no significant disincentives to work were generated by the programme, given that it did not discourage adults from working or lead to a reduction in the number of hours worked. These findings are highly relevant in the Latin American context where these kinds of cash transfers have become an important component of social protection systems.

On the allowance for support costs in Prager-Rozvany’ optimal layout theory

A recent study by Rozvany and Sokól discussed an important topic in structural design: the allowance for support costs in the optimization process. This paper examines a frequently used kind of support —that of simple foundation with horizontal reaction by friction— that appears no covered for the Authors’ approach. A simple example is examined to illustrate the case and to apply the Authors’ method and the standard design method.

Evidence for a recommended dietary allowance for vitamin C from pharmacokinetics: A comment and analysis

The current recommended dietary allowance (RDA) for vitamin C, as proposed by the Food and Nutrition Board/National Research Council in 1980 and reconfirmed in 1989, is 60 mg daily for nonsmoking adult males. Levine et al. [Levine, M., Conry-Cantilena, C., Wang, Y., Welch, R. W., Washko, P. W., et al. (1996) Proc. Natl. Acad. Sci. USA 93, 3704–3709], based on a study of vitamin C pharmacokinetics in seven healthy men, have now proposed that the RDA should be increased to 200 mg daily. I have examined, in brief, the experimental and conceptual bases for this new recommendation and its implications for public health and nutrition policy and programs. Using, for illustrative purposes only, data extracted from each of two recent dietary surveys of noninstitutionalized adult males living in households in the Netherlands and the United States, it is predicted that the prevalence of intakes inadequate to meet the individual’s own requirement would be about 96% or 84%, respectively, if the criteria of adequacy used for derivation of the 200 mg RDA are accepted. Depending upon the particular average requirement value for ascorbic acid that might be derived from their data, the proposal by Levine et al. would mean a desirable increase in mean intakes in these two populations by as much about 2- to 3-fold. Hence, before an action of this kind is to be recommended, an answer must be sought to the question whether current experimental data including the criteria selected (saturation kinetics) are adequate to establish a new set of requirements for vitamin C, which then carry such profound policy implications. This will require critical assessment of all of the available evidence emerging from laboratory, clinical, and epidemiological studies to determine whether it provides a sufficient rationale for accepting criteria of vitamin C adequacy such as those proposed by Levine et al. and the requirement estimates so derived.
