I cambi a termine: rapporti tra teoria e pratica. (The relations between practice and theory of forward exchange)
Creators: name: EINZIG, P.
Publisher: name: Moneta e Credito
Year: 2014
Subjects: subject: Forward exchange theory, theoretical analysis, practical experience
subject: F31

description: Within the economic sphere of Forward Exchange theory a close relationship between theory and practice is essential. On the one hand is a highly intricate system, the immense variety of technical details of which cannot be mastered adequately without a thorough practical experience. On the other hand, is an important set of economic principals arising from the study of that system with all its manifold implications, which cannot be mastered adequately without being familiar with methods of theoretical analysis. Most foreign exchange dealers are not trained to grasp its theoretical aspects, while most academic economists fight shy of Forward Exchange. The author criticises the shortcomings and defects on both sides, and stresses the need for closing the gap between theory and practice in forward exchange. JEL: F31

The overview characterizes adaptation algorithms as based on embeddings, model parameter adaptation, or data augmentation. We present a meta-analysis of the performance of speech recognition adaptation algorithms, based on relative error rate reductions as reported in the literature.

description: Axial segregation of a binary mixture of grains in a rotating drum is studied using Molecular Dynamics (MD) simulations. A force scheme leading to a constant restitution coefficient is used and shows that axial segregation is possible between two species of grains made of identical material differing by size. Oscillatory motion of bands is investigated and the influence of the frictional properties elucidated. The mechanism of bands merging is explained using direct imaging of individual grains.
title: The statistical properties and coding of handwriting and hand-drawn graphics in tutorial classes
Creators: name: Guifo Guifo, Robinson
Publisher: name: The Open University
Year: 1989

description: This research investigates compression techniques as applied to input from a digitizing tablet. The representations we consider are either drawn from the literature or developed within this thesis; they involve selecting relevant points along the trajectory of the writing pen, and using an interpolating function for reconstruction. The two dimensional parametric polynomial interpolator (e.g linear, quadratic, cubic ) is used for regenerating the trajectory of the pen. Several techniques for selecting relevant points , i.e control points are discussed. We determine our best representation by weighting the criteria, analyzing the experimental results, examining the theoretical considerations and, making where necessary, justifiable tradeoffs. The techniques tested are objectively evaluated in terms of accuracy, efficiency and compactness.

The information characteristics (i.e signal entropy) of the handwriting and drawing signals, are estimated from the original and approximated data. Results are discussed and conclusions drawn. The research has been carried out on static data.

description: The article suggests that, contrary to popular belief, banks can play a useful role in foreign exchange speculation if they are given a chance to draw a permanent profit from it and are convinced of the ability of the monetary authorities to maintain the exchange rate within certain pre-established boundaries. The author proposes a model to argue that banks’ speculative activity is beneficial both in stabilising the exchange rate in the face of non-speculators’ operation and in repelling a sudden attack by occasional speculators.

description: Administrative and transaction-related costs have a long-established position in economic sciences, including agricultural economics. Unfortunately, so far economists have not created a uniform methodology for defining, classifying, and measuring them. The direction that perhaps should be considered most promising when seeking advancements in this field is the Standard Cost Model (SCM) and its derivatives (e.g. ACM). However, it needs to be supplemented with tools from the area of new public management that is Public Value, CAF, or the ISO 9001 standards. As regards financial interventionism, administrative and transaction- -related costs first made their appearance in the area of credit subsidies. It was much later that the research focused on the evaluation of the overall “tool kit” of financial and budgetary policy in agriculture. It has been conducted, however, on the basis of different methodologies which hampers the comparison of the produced results. Also, the test samples were often too small to be used in the more advanced quantitative analyses.

description: We propose a new method for finding discrete eigenvalues for the direct Zakharov-Shabat problem, based on moving in the complex plane along the argument jumps of the function $a(ζ)$, the localization of which does not require great accuracy. It allows to find all discrete eigenvalues taking into account their multiplicity faster than matrix methods and contour integrals. The method shows significant advantage over other methods when calculating a large discrete spectrum, both in speed and accuracy.

description: The predominant Ni-multiorbital nature of infinite-layer neodynium nickelate at stoichiometry and with doping is revealed. We investigate the correlated electronic structure of NdNiO$_2$ at lower temperatures and show that first-principles many-body theory may account for Kondo(-lattice) features. Yet those are not only based on localized Ni-$d_{x^2-y^2}$ and a Nd-dominated self-doping band, but heavily builds on the participation of Ni-$d_{z^2}$ in a Hund-assisted manner. In a tailored three-orbital study, the half-filled regime of the former inplane Ni orbital remains surprisingly robust even for substantial hole doping $δ$. Reconstructions of the interacting Fermi surface designate the superconducting region within the experimental phase diagram. They furthermore provide clues to recent Hall measurements as well as to the astounding weakly-insulating behavior at larger experimental $δ$. Finally, a strong asymmetry between electron and hole doping, with a revival of Ni single-orbital features in the former case, is predicted. Superconductivity in Nd$_{1-x}$Sr$_x$NiO$_2$ is unlike the one in cuprates of distinct multiorbital kind, building up on nearly localized Ni-$d_{x^2-y^2}$ and itinerant Ni-$d_{z^2}$.

title: Unwanted pathways : a material flow analysis of plastics from production to the ocean
Creators: name: Kellen, Vera
Publisher: name: TU Wien
Year: 2014
Subjects: subject: Material Flow Analysis
subject: Marine pollution
subject: Gyres
subject: Unwanted Sinks
subject: Plastics

description: The accumulation of microplastics in the world-s oceans has been all over the media since the discovery of the Great Pacific Garbage patch in 1997. Although the impacts of plastics on the marine ecosystem and the amounts in the gyres have by now been quite extensively covered in literature, research regarding the journey of the plastic debris from source to sink is still scarce. Consequently, this thesis aims to identify the major pathways of synthetic polymers from anthropogenic sources to the 5 accumulation zones in the oceans, including closer scrutiny on how the Tohoku tsunami of 2011 impacted the flows and stocks. The results are based on thorough literature review and are presented as a global material flow analysis (MFA) to point out the extent to which each source contributes to the prevalence of plastic in the five gyres of the world's oceans. The presentation of the results as an MFA aims to support future policy-making and provide research incentives in marine pollution prevention. The research shows that of the 285Mt of plastics produced in 2014, 4.76Mt entered the marine environment as beach litter, depositions on the seafloor and microplastics in the gyres. The main flows towards the gyres were identified as 0.4Mt/year extra-gyral input of beach litter as well as 0.3Mt/year inflow from anthropogenic pre-and postconsumer plastic stocks in the case of a tsunami. The flow of litter towards the beach stemmed mainly from uncollected plastics, amounting to 0.56Mt/year, and dumpsite leaking, equaling 4.19Mt/year as of 2014. The study further showed that the shipping industry and related export activities have only a minor impact on the plastic abundance in the ocean, with an input of a mere 0.044Mt/year. Additionally, the comparison between every year flows and tsunami induced flows showed a doubling of the input to the gyres caused by a single event in one region of the world. This underlines the role of efficient waste management prior to the event, as well as quick disaster response, in reducing the input of plastic material to the gyres. The overwhelming scarcity of data in this section of marine debris research made it necessary to base a substantial part of this thesis on extrapolation and estimations: It is therefore concluded that further research needs to be done to properly quantify the different flows of plastic to the ocean and identify the most efficient way in preventing plastic from damaging the marine ecosystem.

description: The intensity of business merges and acquisitions changes over time. Theoretically, competitive companies constantly seek for ways to grow, mainly due to expected economies of scale and scope. In the paper we discuss various aspects of business mergers and acquisitions in the context of market concentration. We also highlight the issue of symptoms and causes of fluctuations in economic activity. Using data for the period of 2000-2012 we analyse the value of the overall business mergers and acquisitions in connection with the global economic growth and selected stock market indices. Next, we focus on the global agro-food sector and test the hypothesis that the number and value of mergers and acquisitions in this sector were related to the business cycle fluctuations observed in the period of 2000-2010. Firstly, the results of our research show that both merger and acquisition transactions carried out in the agro-food sector had largely inter- -branch or, at the most, inter-sectorial character. Secondly, a positive relationship between fluctuations in economic activity in the global agro- -food sector and the intensity of mergers and acquisitions was found, especially regarding the value of those transactions, what means that economic recovery facilitates concentration processes. Thirdly, the observed connection between the directions of changes in the merger and acquisition activities and the changes in stock market indices seems to be determined by the situation on the capital markets.

description: In this study the cognitive abilities underlying math excellence among children are examined, with a focus on children of high mathematical ability. The relationship between cognitive functioning—as defined by the Cattell-Horn-Carroll (CHC) theory—and academic achievement among children who excel in mathematics is explored in order to understand-whether strong math skills correspond to any "typical" cognitive ability profile(s). Results suggest that Short-Term Memory, Working Memory, and Visual/Spatial Thinking are significant predictors of strong and specific achievement in math calculation skills, whereas Fluid Reasoning is a significant predictor of strong and specific achievement in math reasoning. The results outlined in this study may supplement the existing research body relating to the full range of mathematics ability.

description: Controlling acoustic phonons, the carriers of sound and heat, has been attracting great attention toward the manipulation of sonic and thermal properties in nanometric devices. In particular, the photo-acoustic effect using ultrafast optical pulses has a promising potential to optically manipulate phonons in picoseconds time regime. However, its mechanism has been so far mostly based on the commonplace thermoelastic expansion in isotropic media, limiting the spectrum of potential applications. We investigate a conceptually new mechanism of photo-acoustic effect involving the structural instability, by utilizing a transition-metal dichalcogenide VTe$_2$ with the ribbon-type charge-density-wave (CDW). Ultrafast electron microscope imaging and diffraction measurements reveal the generation and propagation of unusual acoustic waves in the nanometric thin plate associated with the optically induced instantaneous charge-density-wave dissolution. Our results highlight the capability of photo-induced structural instability as a source of coherent acoustic waves.

title: Heterocycles in peptide chemistry
Creators: name: Hollis, Stephen James
Publisher: name: The Open University
Year: 2000

description: The synthesis of 5-membered heterocyclic rings that bear both amine and carboxylic acid functional groups has been investigated using a 1,3-dipolar cycloaddition reaction strategy. These molecules, on incorporation into a chain of amino acids, have the potential to restrict the conformational freedom of the peptide.

 Cycloaddition of a nitrile oxide, derived from a Boc-protected naturally-occurring a-amino acid, with a pyrrolidine en amine led to a Boc-protected 3-aminoalkylisoxazole amino acid ester. The nitrogen and carbon termini of this isoxazole were coupled to other a-amino acids. Analysis of the dipeptide from coupling to (S)-alanine indicated that the integrity of the chiral centre of the isoxazole had been retained during the synthesis. Molecular modelling of a tripeptide unit incorporating the isoxazole showed that the presence of the ring had, as intended, restricted the conformational freedom of the molecule.

Analogous cycloadditions using azomethine imines as the dipole yielded the corresponding tetrahydropyrazoles (pyrazolidines). These dipoles were generated by reaction of an aldehyde with a 1,2-disubstituted hydrazine, followed by elimination of the elements of water from the resulting aminol. Reaction with a dipolarophile bearing an electron withdrawing substituent gave predominantly the 4-substituted pyrazolidine. A study of the scope of the reaction found that, although the required carboxylic acid group could easily be incorporated by use of methyl acrylate as the dipolarophile, it proved impossible to attach an amine group to the ring using this methodology. However, by using one of the nitrogen atoms in the ring as the N-terminus, two pyrazolidines with protected amine and carboxylic acid groups were prepared, and these can be thought of as conformationally restricted B-amino acids.

description: The aim of the paper is to identify and to evaluate the competing strategies of Polish food producers in the German market in 2004-2014. Two research methods were employed, that are relative price indices in Polish agri-food export to Germany in regard to the other competitors as well as price and quality indices by Aiginger. The analysis covers the agri-food products (chapters 01-24 by HS classification). The research results show that in 2004-2014 price advantages of Polish food producers were the main source of increase of the Polish agri-food export to Germany. The quality advantages were also important, however, during the period in question the quality gap between Polish agri-food products in German market and agri-food products of the other competitors only slightly diminished. / Synopsis. Celem referatu jest identyfikacja i ocena strategii konkurowania polskich producentów żywności na rynku niemieckim w latach 2004-2014. W tym celu zastosowano dwie metody badania konkurencyjności cenowo-jakościowej, tj. wskaźniki cen relatywnych w polskim eksporcie na rynek niemiecki względem konkurentów z innych krajów oraz wskaźniki jakościowo-cenowe według koncepcji K. Aigingera. Analizą objęto produkty rolno-spożywcze (działy 01-24 według klasyfikacji HS). Przeprowadzone badanie wykazało, że w latach 2004-2014 źródłem wzrostu polskiego eksportu rolno-spożywczego do Niemiec były głównie przewagi cenowe polskich producentów żywności. Nie bez znaczenia były również przewagi o charakterze jakościowym, jednakże w analizowanym okresie tylko nieznacznie zmniejszyła się luka jakościowa między polską ofertą eksportową produktów rolno- spożywczych na rynku niemieckich a ofertą konkurentów z innych krajów.

description: We report a series of layered superconductors, anti-ThCr$_2$Si$_2$-type $RE_2$O$_2$Bi ($RE$ = rare earth), composed of electrically conductive Bi square nets and magnetic insulating $RE_2$O$_2$ layers. The superconductivity was induced by separating Bi square nets as a result of excess oxygen incorporation, irrespective of the presence of magnetic ordering in $RE_2$O$_2$ layers. Intriguingly, the transition temperature of all $RE_2$O$_2$Bi including nonmagnetic Y$_2$O$_2$Bi was approximately scaled by the unit cell tetragonality ($c$/$a$), implying a key role of relative separation of the Bi square nets to induce the superconductivity.

description: Urbanisation and increasing risks for natural hazards due to Climate Change will lead to a large number of people to be threatened by natural disasters in the future (IPCC, 2013; United Nations, 2012; Dilley et al., 2005). It will therefore become increasingly necessary to make cities more -resilient- to those risks. This thesis will first look at the outcome of recent urban planning practices to show the need for the rather new concept of urban resilience. It will be seen that deregulation under the neoliberal agenda and the increasing pressure of globalisation have destroyed the urban system-s self-regulating capacities and have led to high economic and social vulnerability (Eraydin, 2013). A new planning model should therefore aim at reducing these vulnerabilities by enhancing the system-s adaptive capacity, self-organisation, and transformability. Furthermore, the concept of urban resilience is the first to acknowledge uncertainties and the fact that cities are dynamic, socio-ecological systems interacting with their environment. Second, to provide a sound basis for this new model of planning, it will be evaluated whether there is a way to assess urban resilience. To this end different existing approaches will be compared (U.S. Indian Ocean Tsunami Warning System Program, 2007; Asian Cities Climate Change Resilience Network (ACCCRN), 2009; Prasad et al., 2009; Normandin et al., 2009; Tanguay et al., 2010) and it will be shown that the Climate Disaster Resilience Index (CDRI) is the first comprehensive approach to deal with the issue (Shaw and Sharma, 2011a; Climate and Disaster Resilience Initiative, 2010; Shaw and Sharma, 2011b). A case study on the city of Vienna, Austria, will demonstrate how the CDRI assessment method can be applied in practise and how the findings will give guidance for further planning action in the sphere of disaster risk reduction (DRR). It will be shown that while Vienna is generally well-prepared to handle disturbances, there are certain areas which still need improvement and that problems need to be tackled comprehensively. The index will therefore prove to be a valuable tool to reveal strengths and weaknesses of an urban system and to provide guidance for future policy-making.

description: The Arctic Ocean is at the frontier of the fast-changing climate in the northern latitudes and sea level trends is a bulk measure of ongoing processes related climate change. Observations of sea level in the Arctic Ocean are nonetheless difficult to validate with independent measurements and is globally the region where the sea level change is most uncertain. By using specialized methods for observing sea level with satellite altimetry over sea ice regions in the Arctic, we are able to construct an altimetric sea level record that is in good agreement with the sea level observed by tide gauges. However, long-term changes of tide-gauges are influenced by vertical land motion (VLM) caused by past and present changes of ice. A novel model of the elastic rebound from present changes of Arctic ice has been applied to create a VLM-model that agrees well with GNSS. Sea level change from altimetry and VLM-corrected tide gauges are compared to a reconstructed sea level estimate, derived from the sea level fingerprints of present-day mass changes and steric sea level change derived from available arctic T/S-profiles. The comparison shows that the freshwater change is dominating the Arctic sea level change. Several recommendations have been outlined, to improve future analysis and observations of Arctic Ocean sea level. The most important is the lack of in-situ data in several regions of the Arctic Ocean that are necessary to validate the observations from remote sensing.

description: We present our recent studies on the dynamics of boundary N=2 Liouville theory. We use the representation theory of N=2 superconformal algebra and the method of modular bootstrap to derive three classes of boundary states of the N=2 Liouville theory. Class 1 and 2 branes are analogues of ZZ and FZZT branes of N=0,1 Liouville theory while class 3 branes come from U(1) degrees of freedom. We compare our results with those of SL(2;R)/U(1) supercoset which is known to be T-dual to N=2 Liouville theory and describes the geometry of 2d black hole. We find good agreements with known results in SL(2;R)/U(1) theory obtained by semi-classical analysis using DBI action. We also comment on the duality of N=2 Liouville theory.

description: Food losses and wastes in the global food supply chain is not a new problem, but the gap of current, reliable information remains. The following paper aims to narrow this gap with a three part approach. First, this paper presents the global food system from a mass flow perspective using the most current statistics and methodology available. Highlighting the magnitude of losses and wastes at each stage of the food supply chain, from farm to feces. Next, the "average global diet" represents the ten most abundantly consumed foods on the planet in a mass flow perspective, in order to compare the losses and wastes between the two. Lastly, relevant trends in the global food mass flow and global diet mass flow are compared and discussed in order to assess the current state of global food loss and waste. Determining where the largest proporations of food loss and waste occure throughout the food chain allows for evidenced based decision making to address some of the unsustainable aspects of the current global food supply chain.

description: We study the Higgs sector in the Next-to-Minimal Supersymmetric Standard Model with and without explicit CP violation, focusing on the case of weak scale expectation value of the singlet field. We scan a wide range of the parameter space to find out allowed regions by requiring that the electroweak vacuum be the global minimum of the effective potential and that the neutral Higgs bosons with moderate gauge coupling be heavier than the lower bound on the Higgs boson in the standard model. Among the allowed parameters, some sets admit the situation in which the light Higgs bosons couple with the $Z$ boson too weak to be found in present collider experiments. For such parameter sets, we find an upper bound on the charged Higgs mass which is reachable in LHC.

description: We use the functional renormalization group equation for the effective average action to study the fixed point structure of gravity-fermion systems on a curved background spacetime. We approximate the effective average action by the Einstein-Hilbert action supplemented by a fermion kinetic term and a coupling of the fermion bilinears to the spacetime curvature. The latter interaction is singled out based on a "smart truncation building principle". The resulting renormalization group flow possesses two families of interacting renormalization group fixed points extending to any number of fermions. The first family exhibits an upper bound on the number of fermions for which the fixed points could provide a phenomenologically interesting high-energy completion via the asymptotic safety mechanism. The second family comes without such a bound. The inclusion of the non-minimal gravity-matter interaction is crucial for discriminating the two families. Our work also clarifies the origin of the strong regulator-dependence of the fixed point structure reported in earlier literature and we comment on the relation of our findings to studies of the same system based on a vertex expansion of the effective average action around a flat background spacetime.

title: The timing of prograde metamorphism in the Garhwal Himalaya, India
Creators: name: Prince, Christophe Iain
Publisher: name: The Open University
Year: 2000

description: The Himalaya provide the most significant example of present-day orogenesis and consequently have been extensively studied to gain an understanding of the principle controls on the response of the crust to continental collision. However, our understanding of the prograde metamorphic evolution of the orogen remains poor. This thesis builds on recent advances in the study of PTt paths, using garnet chronometry, to better constrain the thennobarometric evolution of the Garhwal section of the Indian Himalaya. Results show that the metamorphic core of the Garhwal Himalaya - the High Himalayan Crystalline Series (HHCS) - records a complex, continuous prograde thermal history from initial burial -10 Ma after continental collision at -50 Ma, up to cooling and exhumation at 20-16 Ma BP. PT paths obtained from garnets indicate that prograde metamorphism occurred during crustal thickening and "peak" thermobarometric estimates show that the presently exposed HHCS records temperatures of -700 °C throughout the section accompanied by a decrease in pressures from --13 kbar at the base to -6 kbar at the top. However, chronometric information shows that reorganisation of the orogenic wedge resulted in the juxtaposition of rocks which attained different PT conditions at different times and places during orogenesis. Additionally, temperatures were sufficient in the early stages of orogenesis for the development of small leucogranitic bodies to form by fluid-present melting. The HHCS in Garhwal, therefore, cannot be considered as a single coherent crustal slice. Furthermore, the continued reorganisation of the orogen since collision also means the heat generation within the overthickened orogenic wedge is sufficient for anatexis of the crust to form the well-studied melts intruding the upper levels of the HHCS.

 However, interpretation of the results is complicated by the isotopic systematics involved in garnet chronometry and by the role of small inclusions with high concentrations of the critical elements of- Nd, Pb, Sr. The systematics of the Sm-Nd system in garnet has been investigated by a comparison of concentrations obtained insitu by LA-ICP-MS with those obtained by isotope dilution. Results show that while such inclusions can pose a problem to chronometry, their effects can be identified and constrained.

 In the course of such work data was obtained on the trace-element zonation in garnet, which acts as a monitor of the chemical evolution of the rock. While the controls on such zonation are still poorly understood the data presented here emphasise the importance of fractionation of the chemical system from which the garnet grows by both accessory minerals and by garnet itself. Furthermore, different minerals fractionate distinctly different elements this can be recognised in the trace-element zonation preserved in garnet.
La speculazione su cambi esteri ed i trasferimenti internazionali di fondi privati (parte seconda) (The role of commercial banks in foreign exchange speculation)

Subjects: subject: Banks, foreign exchange speculation, monetary authorities, exchange rate
subject: F31, G21, E58

description: The article suggests that, contrary to popular belief, banks can play a useful role in foreign exchange speculation if they are given a chance to draw a permanent profit from it and are convinced of the ability of the monetary authorities to maintain the exchange rate within certain pre-established boundaries. The author proposes a model to argue that banks’ speculative activity is beneficial both in stabilising the exchange rate in the face of non-speculators’ operation and in repelling a sudden attack by occasional speculators.

Gran Bretagna, Commonwealth e Mercato Comune. (Britain, the Commonwealth, and the European Common Market)

subject: F13, F36, F33

description: The article considers the patterns of British trade with the Commonwealth and the rest of the world in order to assess the economic gains and losses Britain may derive from participation in the European Common Market. Given the amount of trade and the rate of preferential duties, it can be suggested that, under static assumptions, the loss in resource allocation due to the abolition of present preferential arrangements may offset the gain Britain would derive from entry into the EEC. In addition to gains and losses from the reallocation of resources, it is necessary to also consider possible changes in the terms of trade, which point towards a deterioration of Britain’s terms of trade upon entry into the EEC.

The stellar IMF of Galactic clusters and its evolution

description: We show that one can obtain a good fit to the measured main sequence mass function (MF) of a large sample of Galactic clusters (young and old) with a tapered Salpeter power law distribution function with an exponential truncation. The average value of the power law index is very close to Salpeter (~2.3), whereas the characteristic mass is in the range 0.1 - 0.5 Msolar and does not seem to vary in a systematic way with the present cluster parameters such as metal abundance and central concentration. However, a remarkable correlation with age is seen, in that the peak mass of young clusters increases with it. This trend does not extend to globular clusters, whose peak mass is firmly at ~0.35 Msolar. This correlation is due to the onset of mass segregation following early dynamical interactions in the loose cluster cores. Differences between globular and younger clusters may depend on the initial environment of star formation, which in turn affects their total mass.

description: The paper addresses matrix spaces, whose properties and dynamics are determined by Dirac matrices in Riemannian spaces of different dimension and signature. Among all Dirac matrix systems there are such ones, which nontrivial scalar, vector or other tensors cannot be made up from. These Dirac matrix systems are associated with the vacuum state of the matrix space. The simplest vacuum system realization can be ensured using the orthonormal basis in the internal matrix space. This vacuum system realization is not however unique. The case of 7-dimensional Riemannian space of signature 7(-) is considered in detail. In this case two basically different vacuum system realizations are possible: (1) with using the orthonormal basis; (2) with using the oblique-angled basis, whose base vectors coincide with the simple roots of algebra E_{8}. Considerations are presented, from which it follows that the least-dimension space bearing on physics is the Riemannian 11-dimensional space of signature 1(-)& 10(+). The considerations consist in the condition of maximum vacuum energy density and vacuum fluctuation energy density.

Educational and psychological effects of childhood chronic illnesses
Creators: name: Martinez, Yvonne Julia
Publisher: name: University of British Columbia
Year: 2011

description: The numbers of children affected by a chronic physical illness have steadily increased over the last few decades with current prevalence estimates at as many as 20% of school-aged children affected. For children with a chronic illness, the prevalence of educational and psychological problems is nearly doubled in comparison to the general population. The purpose of this research is to investigate the educational and psychological effects of childhood chronic illness among Canadian children. This project will be a retrospective analysis using data from the National Longitudinal Survey of Children and Youth (NLSCY), taking a cross-sectional look at the relationships between childhood chronic illnesses, performance on a Mathematics Computation Exercise (MCE), and ratings on an Emotional Disorder - Anxiety scale (EDA). A total of 1,644 children (ages 10-15) across Canada were included in the analyses. The results showed that when EDA ratings and educational handicaps were controlled for, children identified with chronic illnesses still have weaker performance on the MCE test. However, illness did not appear to have an impact on children's EDA ratings. The regression analysis indicated that community type and illness were the strongest predictors of MCE scores. Limitations of the study are discussed, and implications of the findings and directions for future research are highlighted.

description: Several economic and political problems have arisen from the fall in commodity prices over the last ten years. The existing international commodity agreements, while useful, in practice face several difficulties. For this reason, the article proposes a development insurance fund to stabilise export proceeds. These schemes do not attempt to influence the terms of trade or to stabilise market price or output. Therefore, their operation in relation to commodity agreements requires further investigation.
