Getting Normalization Right: Dealing with 'Dimensional Constants' in Macroeconomics
No full textWe contribute to a recent literature on the normalization, calibration and estimation of CES production functions. The problem arises because CES 'share' parameters are not in fact shares, but depend on underlying dimensions - they are 'dimensional constants' in other words. It follows that such parameters cannot be calibrated, nor estimated unless the choice of units is made explicit. We use an RBC model to demonstrate two equivalent solutions. The standard one expresses the production function in deviation form about some reference point, usually the steady state of the model. Our alternative, 're-parametrization', expresses dimensional constants in terms of a new dimensionless (share) parameter and all remaining dimensionless ones. We show that our 're-parametrization' method is equivalent and arguably more straightforward than the standard normalization in deviation form. We then examine a similar problem of dimensional constants for CES utility functions in a two-sector model and in a small open economy model; then re-parametrization is the only solution to the problem, showing that our approach is in fact more general.
A comparative study of the FET phase mathematical literacy and mathematics curriculum
No full textThis article is based on a study that compared the FET (further education and training) phase mathematics literacy curriculum and mathematics curriculum. The study looked into how the conceptualization of a mathematical literacy curriculum enhanced the acquisition of mathematical concepts among the learners. In order to carry out this comparison between the two curricula, views of 355 participants comprising of mathematics and mathematical literacy teachers, mathematics and mathematical literacy subject advisors and heads of departments at the MST (mathematics, science and technology) units were sought. The findings of the study revealed that both curricula have similar learning outcomes, but different assessment standards. Factors that hinder the learning and teaching of mathematics in both curricula, such as lack of qualified mathematics teachers, lack of parental support, negative societal attitudes towards mathematics and lack of support from the Department of Education among others, were identified by the study. Intervention mechanisms, such as the use of information technology as an instructional tool, contextualized teaching and learning materials for mathematics, recruiting and training mathematics teachers and continuous professional development, were suggested. Further research is necessary for exploring the benefits of cross-curriculum teaching and learning of mathematical literacy as a way of enhancing the acquisition of mathematical skills at the FET phase
On the dangers of decentralization
No full textThe author highlights some of the dangers of decentralizations. The benefits of decentralization in allocative efficiency are not as obvious as suggested by the standard theory of fiscal federalism. The assumptions of this theory are fragile. These doubtful benefits might carry a cost in production efficiency, but more empirical research is needed on this point. What is not doubtful is that decentralization runs counter to redistribution and stabilization. Decentralization makes redistributive policies, whether interpersonal or interjurisdictional, more difficult, if not impossible. Decentralization also makes macroeconomic stabilization programs more difficult to implement because subnational government fiscal policies can run counter to national policies. Serious drawbacks or potential drawbacks should be considered in designing any decentralization program. The arguments that the author develops make it easier to understand some of the real choices. These choices are not so much whether to decentralize in general but rather what functions to decentralize - in which sectors, and in which regions. Guidelines can be provided on this. Often, the problem is not so much whether a certain service should be provided by a central, regional, or local government, since the service often has to be provided with the intervention of all three levels of government. The real challenge is how to organize the joint production of the service. Decentralization refers simultaneously to a state and to a process. The virtues and dangers of decentralization are often discussed simultaneously for both concepts. This is a dangerous confusion because decentralization is path-dependent. What is desirable in a given country at a certain point in time depends on the present state of decentralization and the speed at which it has been reached. Much more work, particularly empirical work, is needed -- in review of decentralization (or centralization) experiences in general, as well as those encouraged or supported by the World Bank.National Governance,Banks&Banking Reform,Municipal Financial Management,Economic Theory&Research,Pharmaceuticals&Pharmacoeconomics

Abstract
The aim. To research the impact of chronic heart failure within different origin in case of polytrauma without myocardial injury.
Materials and methods. The study the analyzed results of intensive care in 95 patients with polytrauma between the ages of 25 and 83. All patients were divided into 3 groups. Group C included 29 patients without chronic heart failure (CHF), groups C - 33 patients with CHF, the presence which was confirmed by the level of NT-proBNP more than 100 pg/ml, group E - 33 patients with CHF. Patients of groups K and C received standard intensive care, patients of group E additionally received ethylmethylhydroxypyridine succinate (EMGPS). The study was carried out at three stages: during admission to the hospital, at the 3rd and 7th day. During admission, the level of Th I was determined in order to exclude traumatic or other acute myocardial lesions. At a concentration of Tn I more than 0.3 ng/ml, patients were not included in the study.
Results. During admission, NT-proBNP level in all K-group patients did not exceed 87 pg/ml throughout the study. The ejection fraction (EF) was averaged 53,7±3,4%. The NT-proBNP dynamics were as followed by 116.4±7.0, 114.4±7.4, 109.1±8.5 pg/ml. The NT-proBNP and EF correlation coefficient was according to the stages -0.84±0.06, -0.74±0.08, -0.68±0.09. The value of the EF at hospitalization in group C was 47.9±4.7%, on the 3rd day 52.2±5.2% (p < 0.001), and by 7th - until 56.8±6.9% (p < 0.001). NT-proBNP level in E patients: 119.2±10.8, 113.2±8.1 (p= 0.02), 65.2±23.3 (p < 0.0001). At stage 1 and 2, a strong negative correlation effect was observed (-0.78±0.07 and -0.77±0.07, accordingly), at the 3 stage the communication disappeared (0.07±0.17). Within admission EF level was 47.5±6.9 %.
Conclusions. The level of NT-proBNP authentically reflects the relationship with chronic heart failure. There is also a strong correlation between NT-proBNP and EF. Therefore, it is clear from the study that NT-proBNP has not undergone changes in group K (87 pg/ml), in contrast to patients of groups C (116.4±7.0,114.4±7.4, 109.1±8.5 pg/ml) and E (119.2±10.8, 113.2±8.1 (p =0.02), 65.2±23.3 (p < 0.0001) who had concomitant disorder such as chronic heart failure.

A gazetteer and summary of French pottery imported into Scotland c. 1150 to c. 1650 a ceramic contribution to Scotland's economic history Ceramic Resource Disc 3
No full textThe proposal for a series of published inventories, by countries, of all the imported medieval and post medieval pottery recovered from excavations and field walking in Scotland, was advanced on the final day of the Medieval Pottery Research Group’s conference held in Edinburgh in May 2001. Taking on the roll of creating a gazetteer and catalogue of French pottery in Scotland, it was the authors aim to build on the pioneering work of John Hurst and other medieval ceramicists and in the process make a contribution to the ongoing research on identifiable medieval and post-medieval ceramics traded around the North and Irish Sea
Raziskava o visokošolskem izobraževanju odraslih v Sloveniji
No full textIn his study the author first ascertains that there is a general tendency for higher education of adults to become the domain of university; therefore, in 1993, the Centre for the Development of the University decided to carry outa comprehensive research into higher education of adults in this country. lts aim was to ereate a theoretical framework, a description of the past developments and of the present state, a definition of requirements and a statement of proposals for implementation of changes. The main findings of the study indicate that there have been major changes in the higher education of adults in r ece nt years; continuous professional education in its many forms is rapidly spreading; the courses offered to the “irregular” (part-time) student are the same as those offered to the “regular” (full-time) student, but there is less counselling for th e adults. The author establishes that higher education of adults is still lagging behind, a situation resulting from the lack of coordination between - and in activity of - various agents in the system. The study also shows that in Slovenia there are more placements open to adults in the academic or university programs than in the professional programs, which is contrary to what might be expected in view of the nature of parttime studies. ln the conclusion the author suggests that the university should liaise with the other parts of the system, which is the only possible way to make the university evol ve into a community of scientists, teachers and students, not separated by age, a community that will be ready to accept the challenges posed by the environment and foster a cooperation exceeding the framework of science.Avtor v svoji raziskavi najprej ugotavlja, da postaja v svetu visokošolsko izobraževanje odraslih čedalje bolj domena univerze, zato so se na Centru za razvoj univerze že leta 1993 odločili za obširnejšo raziskavo o stanju na tem področju pri nas. Cilji raziskave so bili oblikovanje teoretičnih izhodišč, opis dosedanjega razvoja in ugotovitev trenu tnega stanja, opredelitev potreb ter oblikovanje predlogov za spremembo stanja. Poglavitne ugotovitve v raziskavi so bile, da lahko v zadnjih letih zaznamo bistvene spremembe v visokošolskem izobraževanju odraslih; danes se čedalje bolj razvijajo oblike nadaljnjega strokovnega izobraževanja in izpopolnjevanja, programska ponudba za "izredne" študente je načelno enaka kot za "redne" študente, manj pa je svetovalnega dela z odraslimi. Avtor ugotavlja, da je v visokošolskem izobraževanju odraslih še zmeraj zastoj, katerega vzrok sta nepovezanost in neaktivnost posameznih akterjev v sistemu. Izsledki raziskave so tudi pokazali, da je v Sloveniji več vpisnih mest za odrasle v akademskih (univerzitetnih) programih, manj pa v strokovnih, kot bi lahko že po sami naravi "izrednega" študija pričakovali. Na koncu svojega prispevka pa opozori tudi na pomen povezovanja univerze z drugimi deli sistema in hkrati poudarja, da je to edini način, po katerem bi postala univerza skupnost znanstvenikov, učiteljev in študentov, ki se ne bodo ločevali po starosti, in bo pripravljena na izzive okolja ter na sodelovanje prek okvirov znanosti
