description: We investigate the influence of different interaction strengths and dimerizations on the magnetization transport in antiferromagnetic spin-1/2 XXZ-chains. We focus on the real-time evolution of the inhomogeneous initial state with all spins pointing up along the z axis in the left half and down in the right half of the chain, using the adaptive time-dependent density-matrix renormalization group (adaptive t-DMRG). We find on time-scales accessible to us ballistic magnetization transport for small Sz-Sz-interaction and arbitrary dimerization, but almost no transport for stronger Sz-Sz-interaction, with a sharp crossover at Jz=1. At Jz=1 results indicate superdiffusive transport. Additionally, we perform a detailed analysis of the error made by the adaptive time-dependent DMRG using the fact that the evolution in the XX-model is known exactly. We find that the error at small times is dominated by the error made by the Trotter decomposition, whereas for longer times the DMRG truncation error becomes the most important, with a very sharp crossover at some "runaway" time.

description: Nuclear renaissance is a term coined to describe the introduction of nuclear power programmes in countries, mostly developing and emerging nations, that have not utilised nuclear power for energy generation up to now. In this study a framework for assessing the capabilities of these countries to introduce and sustain nuclear programmes has been developed: the Critical Powers Index. It consists of three separate indices of which the first one, the Preparedness Index, has been adapted from the International Atomic Energy Agency-s Milestone Approach, which deals with legislative and regulatory issues. The other two indices, the Sustainability Index and the Emergency Preparedness Index, take into account factors pertaining to infrastructural and economic development as well as disasters preparedness and stability to allow a holistic analysis of a country-s capabilities. Representative for developed countries that already utilise nuclear power for energy generation, Japan has been chosen for evaluation. Sudan-s analysis has been conducted as a proxy for all developing and emerging countries that are part of the global nuclear renaissance. Results show that less developed countries will be faced with considerable problems pertaining to their general development and are thus recommended to postpone the introduction of a nuclear power programme until these issues have been addressed. Furthermore, it has also become evident that sufficient emergency preparedness is a challenge even for affluent and developed countries like Japan. The Critical Powers Index shows that the introduction of a nuclear power programme needs a holistic approach that not only takes issues directly related to the programme into consideration but also the general level of the country-s development. It is thus recommended that the introductory period of 15 years is extended and the IAEA Milestone Approach reviewed and amended.

description: The main causes of death in most early childhood mortality are diseases which are preventable and curable. This is the reason why childhood mortality is treated as a development issue rather than a simple health problem. Ethiopia is among the places where the rate of such deaths is high, which is an indication of the poor quality of life that its people have. It is important to study the important factors of childhood mortality and design intervention in order to improve the situation. This study attempts to identify the important factors of childhood deaths by using the Ethiopian Demographic and Health Survey conducted in 2011. We have fitted an instrumental variable probit model to identify the structural relation between childhood mortality and maternal, child specific and household related variables. Maternal education, maternal age at first birth, total number of children ever born, access to facilities like toilet, safe water, radio and electricity turned out to be inversely related to childhood mortality while boys, multiple births, dirt floor houses and the use of pollutant cooking fuels are related positively.

title: Wesleyan eucharistic sprituality : its nature, sources and future
Creators: name: Khoo, Lorna Lock-Nah
Publisher: name: The Open University
Year: 2002

description: This thesis argues that there is a distinctive Wesleyan eucharistic spirituality. Looking at the Wesleys' eucharistic practices, theology and sources for these, the writer identifies a spirituality that has three themes. These revolve around the dynamic encounter with a personal Christ, the grace-filled life, the therapeutic growth towards holiness and wholeness. They provide a way of looking at life and the formation of characters which may conform to the image of the Christ. While there were several reasons for the decline of Wesleyan eucharistic spirituality after the death of the Wesleys, the writer maintains that this spirituality can be rediscovered, revived and communicated in new forms so as to impact Methodists around the world who are facing the challenges of the 21st century.

description: The objective of this study was to evaluate the profitability of several alternatives for processing North Carolina apples. The investment alternatives include the production of canned slices, sauce, frozen slices, juice, vinegar, concentrate and essence, and butter. Small, medium and large size plants operating for three different lengths of season were evaluated in which only one of the products was produced. Other plants were designed to process two or more of the products. The plants wer e compared in terms of the internal rates of return expected from each operation. Many of the basic plants yielded rather high rates of return although some lines were ruled out either because they required a high proportion (greater than 18 percent) of the total North Carolina crop or because output levels represented a large proportion (greater than 10 percent) of the national market for that product. The juice plant was the most profitable. All the combined product plants were profitable, yielding rates of return greater than 20 percent at base prices. The plant producing juice and sauce was the most profitable combined-product plant. The profitability of apple processing was very sensitive to change in raw product and final product prices. The conversion rate from raw to finished product also greatly affected the profitability of each plant. Potential investors in processing facilities should find this study useful in planning their investment activities. Investment costs, equipment designs and specifications, and operating costs provide valuable background data for the industry. This information will assist investors in choosing among products and product combinations, sizes of plant, lengths of season, and prices required to attract an adequate raw product supply.

subject: Sustainable Energy Development Trend

description: The delicate ecosystem of the Galápagos archipelago, a world natural heritage because of its unique biodiversity, appreciated by virtue of Charles Darwin's research, is under threat. Flourishing tourism, a growing population and economic development have increased fossil fuel consumption and dependence. The supply of energy has primarily been based on diesel; while during the last ten years, there have been several initiatives to implement renewable energies (REs) on Galápagos. These have been receiving international support after the accident of the oil tanker Jessica in 2001 showed the possible damage oil spills can cause to the delicate ecosystem. In 2007, the Ecuadorian government emphasized the goal to change the energy matrix by announcing the "Zero Fossil Fuel Program for Galápagos". Since then, some of the fossil fuels have been successfully replaced through the implementation of wind energy on San Cristóbal and vegetable oil on Floreana. Additional initiatives plan to repower the solar park on Floreana, to install wind turbines on Baltra, and solar photovoltaic on Santa Cruz, Isabella and Baltra. The goal of this thesis is to assess the sustainability of the current strategy towards a 100% RE-System and to find out why despite these efforts, fossil fuels have not yet been completely removed. For this purpose, adequate sustainability criteria are defined from the outset and are organized around the four major dimensions: technological feasibility, energy security, socio-economic energy equity and environmental sustainability. Based on these the sustainability of the electricity systems of all four of the populated islands are analyzed. This research found that the deployment of RE technologies could not only support the global combat against climate change by reducing CO2 emissions and mitigate other negative effects connected to fossil fuel combustion, but additionally could also increase socioeconomic energy equity by promoting prosperity, increasing affordability and improving quality of life. From this comprehensive analysis, a set of recommendations are formulated and these suggestions aim at providing an inspiration to reconsider and reformulate the Zero Fossil Fuel Program for the Galápagos with a view towards creating a reliable, affordable, environmentally friendly and socially inclusive energy system.

description: The effect of antiferromagnetic spin fluctuations on two-dimensional quarter-filled systems is studied theoretically. An effective $t-J'-V$ model on a square lattice which accounts for checkerboard charge fluctuations and next-nearest-neighbors antiferromagnetic spin fluctuations is considered. From calculations based on large-N theory on this model it is found that the exchange interaction, $J'$, increases the attraction between electrons in the d$_{xy}$ channel only, so that both charge and spin fluctuations work cooperatively to produce d$_{xy}$ pairing.

description: Use value taxation for farm real estate and proposals to reduce the use of property taxes in financing local schools have received widespread attention throughout the United States in recent years. This report presents the results of a study designed to provide information necessary to determine how these (or other) proposals to reduce property taxes are likely to affect owners of farm real estate. A brief description is first presented of property taxes as they are administered in North Carolina. A model is then formulated to determine the extent to which changes in property taxes are capitalized into farm real estate values. The average value per acre of farm real estate on a county basis in North Carolina is regressed on the tax rate and four other categories of explanatory variables relating to agricultural productivity of land, farm size, urban influence, and recreational demand. The estimated relationship explained about three-fourths of the variation in farm real estate values. Al 1 explanatory variables had the hypothesized sign. The results indicate that property tax differentials are largely capitalized into real estate values. There are two important implications. First, a capital gain will accrue to the owner of real estate whose value is enhanced as a result of a reduction in the rate of taxation on real property. Second, the decrease in property taxes wi 11 be less than the decrease in the tax rate. The estimated relationship was used to analyze (1) the effects of a decrease in property taxes for farmers versus other property owners, (2) the effect of substituting state taxes for local property taxes, and (3) the potential effect of 1973 legislation providing for present use value taxation for farm real estate in North Carolina.

description: The work looks at the rise in the price of crude oil, elucidating some economic implications of the issues which a large number of economies will have to face in the near future. The authors first consider the primary impact of the rise in the price of crude on the economy of an importing country considered in isolation. A simple model shows a very sizeable deflationary effect which, to a large extent, can only be offset as a result of deliberate policy decisions. It is also shown how each importing country’s decisions in this matter affect the situation of all others. Some aspects of the international payments problem are then dealt with. JEL: E31, Q41, Q43

description: Energy Security is usually defined as -reliable supplies at reasonable price-. Energy security is the milestone of the whole energy system of the country. The problem is that, achieving energy security is a hard task for the government. For such country as Georgia, which is a transit country, it is highly important to have a precisely defined energy security strategy, in order to overcome the political and economic problems related to energy. Moreover, Georgia has a strategic goal to integrate into the European Union. Therefore, Georgia has to fulfill the obligations taken during the past years. Based on literature review, case studies and interviews carried out with the government officials, the problems were set, solutions found and the conclusions drawn. In conclusion, it turned out that some areas should be more prioritized, the Directives/Regulations of the European Union should be implemented in the Georgian legislation and practically applied in order to secure the energy sector in the future. However, overcoming the problems which nowadays exist in the Georgian energy sector and integrating in the European internal energy market, means being close to the integration into the European Union.

description: This study outlines procedures that can be used to estimate the capitalized value of flue-cured tobacco allotments. Such estimates should be of interest to farmers, bankers, and real estate appraisers . Data on farm sales including information on the value of buildings and timber, acres of cropland, other land, and the pounds of tobacco allotment are used to estimate that part of the sale price of a farm which may be attributed to the tobacco allotments. For 11 flue-cured tobacco counties in the central part of eastern North Carolina, allotment values were estimated to be about $3.50 per pound in 1975, increasing to $4.61 in 1977, and falling to about $3.42 in 1980. Converting these to 1980 dollars, there was a decline in real terms of about 40 percent from $5.40 in 1975 to $3 .24 per pound in 1980. These estimates come from a multiple regression equation which was chosen over many other single-equation models that were tried. The discussion in the final section of Appendix A provides a su1T111ary of the preferred models that were tried and the estimated allotment values from them. The standard error of the estimated value of $3.24 for 1980 was $0 .60 per pound. This means that we are reasonably confident that the true value fell in the range $2.05 to $4.44 per pound. In order to estimate the rate of return to allotment owners, one must also take into account the reduction in the allotted pounds per farm. Flue-cured tobacco allotments were reduced by 21.5 percent from 1974-75 to 1980. A typical Pitt County farm which had 15,000 pounds of tobacco in 1975 would have had only 11,755 pounds in 1980. Allotments worth $52,500 per farm in 1975 ($81,000 in 1980 dollars) were estimated to be worth only $38,086 per farm in 1980. This represents a capital loss of 14 percent per year in real terms. Offsetting this, the owner of tobacco allotments would have had an expected annual net return to allotments, or cash rent, of about 10 percent or $.48 per pound. This means that a typical owner of a tobacco allotment who rented it out lost about 5 percent per year on his investment in allotments over the period 1975-1980. Offsetting this estimated capital loss in allotment values was a 14.4 percent per year estimated capital gain in land values. This, plus an estimated annual income of 4.7 percent from land, leaves a combined return on a typical tobacco farm of 6.7 percent per year before taxes . During this period of time, and especially since 1977, a person would have been much better off owning a farm without a tobacco allotment than one with an allotment. Also, tobacco producers who rented in allotments during these years enjoyed higher returns than those who just produced their own allotments.
title: Mathematical warrants, objects and actions in higher school mathematics
Creators: name: Rodd, Mary Melissa
Publisher: name: The Open University
Year: 1998

description: 'Higher school mathematics' connotes typical upper secondary school and early college mathematics. The mathematics at this level is characterised by moves to (1) rigour in justification,(2) abstraction in content and (3) fluency in symbolic manipulation. This thesis investigates these three transitions - towards rigour, abstraction, and tluencyusing philosophical method: for each of the three transitions a proposition is presented and arguments are given in favour of that proposition. These arguments employ concepts and results from contemporary English language-medium philosophy and also rely crucially on classroom issues or accounts of mathematical experience both to elucidate meaning and for the domain of application. These three propositions, with their arguments, are the three sub-theses at the centre of the thesis as a whole. The first of these sub-theses (1) argues that logical deduction, quasi-empiricism and visualisation are mathematical warrants, while authoritatively based justification is essentially non-mathematical. The second sub-thesis (2) argues that the reality of mathematical entities of the sort encountered in the higher school mathematics curriculum is actual not metaphoric. The third sub-thesis (3) claims that certain 'mathematical action' can be construed as non-propositional mathematical knowledge. The application of these general propositions to mathematics in education yields the following: 'coming to know mathematics' involves:(1) using mathematical warrants for justification and self conviction; (2) ontological commitment to mathematical objects; and (3)developing a capability to execute some mathematical procedures automatically.

description: This report analyzes some likely effects of the recently passed federal cigarette tax increase. An equilibrium displacement model of the cigarette industry is developed. It includes relationships for / international trade in cigarettes and tobacco, federal cigarette taxes, and market interrelationships between cigarettes and tobacco and other inputs in cigarette manufacturing. A range of values for the demand ru1d supply elasticities is used to examine the sensitivity of the calculations. The major results of this study are: (a) the price of cigarettes will rise by almost the full amount of the tax increase; (b) the cigarette price increase will lead to about a 5 to 6 percent reduction in domestic sales of cigarettes, but some increase in quantities exported will offset domestic sales declines; (c) national distribution of cigarette sales will be altered slightly because relative price increases will be largest where current prices (and state tax rates) are lowest; (d) the effect of the tax increase on the price of domestic tobacco will be small -- even holding the production of tobacco constant -- because of the importance of international trade in cigarettes and tobacco as well as substitution with other inputs; and (e) a reduction of the real support price of tobacco in response to the tax increase will cause a fall in average tobacco quota lease rates.

description: This report presents an empirical investigation of price variation among both whole life insurance policies and term insurance policies. It is hypothesized that price differences between policies can be explained by differences in policy contract provisions and differences in selected company characteristics. Information was collected from a sample of whole life policies and term policies marketed in North Carolina in 1982. The empirical results strongly support the hypothesis that policy contract provisions and selected company characteristics account for differences in whole life policy prices; the results indicate that fewer contract provisions and company characteristics are related to differences in term policy prices.

description: This study is a partial evaluation of the effects of the U.S. Plant Variety Protection Act of 1970 (PVPA). It attempts to determine the effect of the Act on expenditures on crop breeding by the private sector, and on the availability and productivity of soybean varieties. A number of other potential effects of the Act, some of them controversial, are mentioned but not addressed in this study. The findings were that both the number of non-hybrid crop breeding programs and expenditures on them increased substantially during the 1970s as compared to the 1960s. It seems likely that these phenomena are due to the incentives created by the Act. Examining the productivity of breeding efforts in soybeans, the study found a three-fold increase in the number of varieties submitted for yield tests in the 1970s as compared to the 1960s. It also found the rate of improvement in yields was greater for varieties released after 1970 than for those released before 1970, although the improvement was significantly different from zero only at the 16 percent confidence level.
Modelling of kraft pulp mill total reduced sulphur emissions
Creators: name: Jensen, Allan Stewart
Publisher: name: University of British Columbia
Year: 2011

description: Atmospheric release of odorous total reduced sulphur (TRS) emissions from kraft pulp mills has been an ongoing concern worldwide. Organic TRS compounds are formed in the digester by undesired side reactions during the kraft pulping of wood. These, along with H₂S, being highly volatile, are released from mill processes, such as brown stock washing. TRS gases are extremely noxious, described as rotting eggs or rotting cabbage, and have a threshold of odour detectability in the range of a few parts per billion. The general objective of this work was to develop and test a method to predict emissions of these TRS compounds from kraft pulp mills using a vapour-liquid equilibrium (VLE) model. This technique could then be utilized to optimize the process to minimize emissions, or to optimize the design and operation of TRS control systems. A mill TRS sampling and testing program was conducted around the brown stock washing area of the Howe Sound pulp mill located in Port Mellon, British Columbia. Over 90% of the sulphur emissions from the TRS compounds were in the form of dimethyl sulphide. This compound was subsequently chosen as a surrogate compound for modelling of TRS. Analytical testing was done on black liquor and various solutions containing the substances found in the highest concentrations in black liquor, including mixed sodium salts solutions to 6 wt% and lignin mixtures to 6 wt%. The VLE of dimethyl sulphide, in the form of an activity coefficient, for these solutions was determined using a headspace gas chromatographic method. The adjustable parameters that provided the best fit for the electrolyte non-random two-liquid (eNRTL) equation for the experimental activity coefficients were determined using statistical regression techniques. Simulation software, incorporating a VLE model using the eNRTL correlation, was used to construct a base-case heat and mass balance representing current operation of the Howe Sound brown stock washing process. This balance was used to evaluate potential process modifications and their effect on TRS emissions.

title: Ethnic differences in illness representations, coping and adjustment in people with coronary heart disease
Creators: name: Timberlake, Natalie
Publisher: name: The Open University
Year: 1999

description: Background and Aims:
There have been few studies examining ethnic differences in people's illness representations. The aim of this research was to explore the relationship between ethnicity and illness representations, coping, perceived health status and psychological adjustment in participants with coronary heart disease (CHD).Furthermore, within a Punjabi group, it aimed to explore the relationship between these variables and acculturation, as well as the relationship between illness representations, coping and adjustment.

Design and Participants:
The study was cross-sectional employing a between and within group design incorporating comparative and correlational analyses. The sample included 47 Punjabi participants and 44 Caucasian participants with diagnosed CHD,recruited from a cardiology clinic and a Gurdwara (Sikh temple).

Measures:
Variables were measured using a range of quantitative questionnaires, which were translated into Punjabi.

Results:
Ethnic differences were found in participants' illness representations and in particular causal beliefs. Only one coping strategy was significantly different between the two groups and there were no differences on perceived health status measures or in anxiety levels. However, the Punjabi group were significantly more depressed. Within the Punjabi group,acculturation was found to be associated with illness representations, coping and physical functioning. Illness representations were associated with adjustment measures, however there were few associations between illness representations and coping, and between coping and adjustment. Overall, ethnicity did not account for any of the variance in perceived physical functioning or anxiety levels, but accounted for 11 percent of the variance in depression levels. Illness representations were more important than ethnicity and coping in accounting for the variance in perceived physical functioning and psychological adjustment. Implications The results are discussed in terms of the self-regulatory model and future research is suggested. Clinical implications for the undertaking of culturally sensitive work with Punjabi clients with CHD, are discussed.

description: For the past several years U.S. exporters of capital equipment and large, turn-key projects have lamented that their competitors in Western Europe and Japan had access to long-term, low-interest rate credit which was not available in the US. They argued that if the U.S. government were to facilitate equivalent types of credit they could significantly increase exports. The credit in question was usually that falling between maturities of 10 and 20 years and between interest rates of 3 and 6 percent. This has come to be referred to as “grey-area” export credit. The present study looks at whether, in fact, U.S. exporters suffered from a lack of this type of export credit. JEL: E43, E51, F13

Creators: name: LUTZ, F.A.
Publisher: name: Moneta e Credito
Year: 2014
Subjects: subject: Inflation, interest rate, theoretical model, Henry Thornton
subject: E31, E43

description: Henry Thornton was the originator of two theories about the connection between inflation and the rate of interest dating back to the early 19th century and which are still discussed today. The first concerns the effect of the interest rate level on inflation. The second deals with the converse relationship, i.e. with the effect of inflation on the level of the interest rate. The present article merges these two theories into a single model. First, however, the author makes some remarks on the results of certain empirical investigations concerning the second problem, i.e. the effect of inflation on the interest rate. JEL: E31, E43

Politiche selettive del credito.
Creators: name: SILBER, W.I.
Publisher: name: Moneta e Credito
Year: 2014
Subjects: subject: Selective credit policies, real, financial effects, control
subject: E51, E52

description: This survey reviews both the theoretical and empirical literature on selective credit policies. The major concern with most of the researchers in this area has been the range of conditions under which selective policies are effective. The author fist looks at selective credit policies and their real versus financial effects. The effectiveness of selective credit policies in theory and in practice is then analysed in order to determine where in the spectrum of conditions the real world fits. Finally, the costs, efficiency and equity of credit controls are considered in the concluding section. JEL: E51, E52

The Theoretical Approach of Ibn al-Mujawir in Tarikh al-Mustabsir

Year: 2020
Subjects: History

description: Ibn al-Mujawir is an unknown Iranian theoretician, whose travelogue, Tarikh al-Mustabsir, despite its theoretical importance, is less known among contemporary researchers. Tarikh al-Mustabsir is a report of Ibn al-Mujawir’s journey into the cities of the Arabian Peninsula in which a first-hand account of the replacement of trading centers and its causes in the first half of the 7th century AH has been presented. One of the remarkable characteristics of the author of the travelogue is that he takes into account the theoretical issues when discussing the causes of the destruction or prosperity of the cities. Despite theorizing about the replacement of the aforementioned centers, Ibn al-Mujawir did not present his theoretical framework explicitly. But through scrutinizing his accounts in Tarikh al-Mustabsir, it can be inferred that the author methodologically based his descriptions and observations on a coherent theoretical framework. His theory is based on the preposition that the decline and destruction of certain urban centers, especially seaport ones, would lead to the prosperity of other urban centers. In this paper, in addition to shedding light on two historical problems related to Ibn al-Mujawir and his travelogue, the theoretical approach of him has been introduced and his theory about the replacement of trading and demographic centers has been studied for the first time by using the method of intentional Hermeneutics. The method of data collection of this paper is library-based.

description: Il proposito dell’articolo è di estrarre dalle congerie di informazioni e dati, spesso effimeri e contradditori, alcune semplici osservazioni riguardanti la necessità di dare un’impostazione “ comunitaria” a un problema che minaccia la sopravvivenza della Comunità europea e la vita economica di ciascuno dei paesi membri e di taluni dei suoi “partners” nel commercio internazionale, in particolare del Giappone e dei paesi del terzo mondo.

Observing Gravitational Radiation with QSO Proper Motions and the SKA
Creators: name: Jaffe, Andrew H.

Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: We discuss the ability of the SKA to observe QSO proper motions induced by long-wavelength gravitational radiation. We find that the SKA, configured for VLBI with multiple beams at high frequency (8 GHz), is sensitive to a dimensionless characteristic strain of roughly $10^{-13}$, comparable to (and with very different errors than) other methods in the 1/yr frequency band such as pulsar timing.

Injective modules and fp-injective modules over valuation rings
Creators: name: Couchot, Francois
Publisher: name: arXiv
Year: 2004
Subjects: subject: Rings and Algebras (math.RA)
subject: FOS: Mathematics

description: It is shown that each almost maximal valuation ring R such that every indecomposable injective module is countably generated, satisfies the following condition (C): each fp-injective module is locally injective. The converse holds if R is a domain. Moreover, it is proved that a valuation ring that sastisfies this condition (C) is almost maximal.

description: New observations of the quasar HE0515$-$4414 have been made using the HARPS spectrograph on the ESO 3.6m telescope, aided by the Laser Frequency Comb (LFC). We present three important advances for $α$ measurements in quasar absorption spectra from these observations. Firstly, the data have been wavelength calibrated using LFC and ThAr methods. The LFC wavelength calibration residuals are six times smaller than when using the standard ThAr calibration. We give a direct comparison between $α$ measurements made using the two methods. Secondly, spectral modelling was performed using Artificial Intelligence (fully automated, all human bias eliminated), including a temperature parameter for each absorption component. Thirdly, in contrast to previous work, additional model parameters were assigned to measure $α$ for each individual absorption component. The increase in statistical uncertainty from the larger number of model parameters is small and the method allows a substantial advantage; outliers that would otherwise contribute a significant systematic, possibly corrupting the entire measurement, are identified and removed, permitting a more robust overall result. The $z_{abs} = 1.15$ absorption system along the HE0515$-$4414 sightline yields 40 new $α$ measurements. We constrain spatial fluctuations in $α$ to be $Δα/α\leq 9 \times 10^{-5}$ on scales $\approx 20\;{\rm km\,s}^{-1}$, corresponding to $\approx25\;$kpc if the $z_{abs} = 1.15$ system arises in a $1\;$Mpc cluster. Collectively, the 40 measurements yield $Δα/α=-0.27\pm2.41\times10^{-6}$, consistent with no variation.

Subjects: subject: Balance of payments deficits, regulation, control, international liquidity
subject: F32, G18, F42

description: The mammoth increase in oil prices has generated correspondingly mammoth balance of payments deficits in the main industrialised countries. This has created serious political problems for Europe, among which, those of a more strictly economic nature require the promptest solution. This work considers the two problems of regulation and control of international liquidity. While very closely linked, the former is mainly characterised by technical aspects, whereas the latter involves more complex considerations on the development of a market economy. JEL: F32, G18, F42

title: Using Technology to Overcome Barriers to the Accreditation of Prior Experiential Learning (APEL)
Creators: name: Mccready, John Edward
Publisher: name: The Open University
Year: 2018

description: There is an extensive range of positive rhetoric concerning the Accreditation of Prior Experiential Learning (APEL) and its many benefits for awarding credit in recognition of one’s experience. However, it still remains very much a marginal activity within many institutions. This study investigates the nature of any existing barriers to the greater take-up of APEL and explores whether technology could play some part in overcoming them. The existence and nature of barriers to wider APEL take-up is under-represented in the literature. This action research study uses qualitative methods to develop a case study within a single UK college of further and higher education. The research design included a focus group for student feedback, semi-structured interviews for staff feedback and the development and testing of a technology solution comprising a website and software application. The study found clear evidence of the existence of a range of barriers affecting the wider uptake of APEL and established several ways in which the technology used did help or could help overcome these barriers. The role of the tutor within the APEL process is of great importance, whether the system used is paper-based or technology based, and further training and support were found to be necessary to ensure that all staff were consistent in the application of the APEL process. Although this is a small-scale study in a single institution, it is typical of other institutions. Further research into the wider range of barriers identified and further development of appropriate technology solutions could help a larger proportion of people in employment to gain credit for the skills and knowledge they have developed through their work, as they seek to complement their practical experience with formal education and gain recognition for this experience though an institution’s APEL process.
