title: Eliciting Individual Preferences for Pension Reform
Creators: name: Fourati, Yosr Abid

Publisher: name: National University of Ireland, Galway
Year: 2009
Subjects: subject: Economics

description: Pension systems have recently been under scrutiny because of the expected population ageing threatening its sustainability. This paper¿s contribution to the debate is from a political economic perspective as it uses data from a choice experiment to investigate individual preferences for an alternative state pension scheme based around preferences for cost, poverty, retirement age and pension parameters. Answers are used to estimate a life-cycle utility model of preferences towards pensions¿ parameters. Results suggest that individuals¿ value orientation is an important determinant of their preferences. Respondents¿ income determines which degree of redistribution is preferred. However, preferences according to age are in contradiction with what is suggested in theory.

description: We have studied the spin dynamics of a high-mobility two-dimensional electron system in a GaAs/Al_{0.3}Ga_{0.7}As single quantum well by time-resolved Faraday rotation and time-resolved Kerr rotation in dependence on the initial degree of spin polarization, P, of the electrons. By increasing the initial spin polarization from the low-P regime to a significant P of several percent, we find that the spin dephasing time, $T_2^\ast$, increases from about 20 ps to 200 ps; Moreover, $T_2^\ast$ increases with temperature at small spin polarization but decreases with temperature at large spin polarization. All these features are in good agreement with theoretical predictions by Weng and Wu [Phys. Rev. B {\bf 68}, 075312 (2003)]. Measurements as a function of spin polarization at fixed electron density are performed to further confirm the theory. A fully microscopic calculation is performed by setting up and numerically solving the kinetic spin Bloch equations, including the D'yakonov-Perel' and the Bir-Aronov-Pikus mechanisms, with {\em all} the scattering explicitly included. We reproduce all principal features of the experiments, i.e., a dramatic decrease of spin dephasing with increasing $P$ and the temperature dependences at different spin polarizations.

Παρόλη όμως τη σημασία τους για την οικονομία και τα σημαντικά βήματα προόδου στα οποία έχουν προχωρήσει οι ελληνικές επιχειρήσεις τροφίμων και ποτών εξακολουθούν να αντιμετωπίζουν σημαντικά προβλήματα που συνιστούν εμπόδια στην περαιτέρω αύξηση της ανταγωνιστικότητας τους. Από την άλλη μεριά η πολύπλευρη σημασία της έννοιας της ανταγωνιστικότητας και οι δυσκολίες στον τρόπο υπολογισμού και εκτίμησης της καθιστούν τη σημασία της ακόμα μεγαλύτερη.

description: The Greek food and beverage industry is on of the most important sectors of the Greek economy taking part with high percentages in its basic rates such as sales, profits, employment value added etc. In spite of the fact that the Greek firms went through significant changes during the last decades, they face too many problems affecting the level of their competitiveness.On the other hand competitiveness is a concern which is difficult to be defined and measured accurately. The aim of this thesis is to study the effect of certain economic factors on the competitiveness of the Greek food and beverage firms using traditional competitiveness measures such as profitability and market share. The estimation of the equations takes part not only for the whole number of the firms but for each sector separately. The results show the way which the different factors affect both on profitability and on market share. The last section of the thesis consists of the conclusions and proposals.

description: In the present paper we describe the properties induced by disorder on an ultracold gas of Bosonic atoms loaded into a two-dimensional optical lattice with global confinement ensured by a parabolic potential. Our analysis is centered on the spatial distribution of the various phases, focusing particularly on the superfluid properties of the system as a function of external parameters and disorder amplitude. In particular, it is shown how disorder can suppress superfluidity, while partially preserving the system coherence.

Different model structures are discussed which have been employed for country-specific, multi-country and region-specific studies. The paper considers the relevance of a relatively recent approach in modeling_linking CGE frameworks with microsimulation models, for the incomes distribution and poverty analysis. Finally we discuss the practical application of this methodology along with a detailed picture of some active CGEmicrosimulation models.
title: Agricultural Biodiversity and Land Fragmentation: the case of Bulgaria

Publisher: name: National University of Ireland, Galway
Year: 2008
Subjects: subject: Economics
subject: Land fragmentation

description: This paper presents an empirical analysis of the role of land fragmentation, crop biodiversity and their interplay with farm profitability. Original primary date are drawn from a survey conducted in Bulgaria. We present two different estimation methods: Seemingly Unrelated Regression and Three Stages Least Squares. The econometric results stress the ambiguous role of land fragmentation on farm profitability. One one hand, land fragmentation reduces farm profitability. On the other hand, land fragmentation fosters crop diversification. Biodiversity also plays a beneficial role in farm profitability. Policies that aim to reduce land fragmentation may overlook the positive link between diversity and plot heterogeneity.
Evidence for out-of-equilibrium crystal nucleation in suspensions of oppositely charged colloids

description: We report a numerical study of the rate of crystal nucleation in a binary suspension of oppositely charged colloids. Two different crystal structures compete in the thermodynamic conditions under study. We find that the crystal phase that nucleates is metastable and, more surprisingly, its nucleation free energy barrier is not the lowest one. This implies that, during nucleation, there is insufficient time for sub-critical nuclei to relax to their lowest free-energy structure. Such behavior is in direct contradiction with the common assumption that the phase that crystallizes most readily is the one with the lowest free-energy barrier for nucleation. The phenomenon that we describe should be relevant for crystallization experiments where competing solid structures are not connected by an easy transformation.

title: The sensitivity of UK agricultural employment to macroeconomic variables 1960-1966
Creators: name: Gaffney, Patrick
Publisher: name: National University of Ireland, Galway
Year: 1998
Subjects: subject: Economics

description: In the UK agriculture continues to have a major impact on the landscape, occupying 77% of the total land area, but its direct contribution to national enlployment is rIlarginal. In 1996 the agricult ural sector accounted for 1. 7% of the British workforce, down from 2.1 % in 1981 and 2.5% in 1971. Some of the reasons for this are the UK's early industrialisation as well as the distinctive inheritance traditions, which have prevented the progressive fragmentation of landed property. Nlore fundanlentally the continued decline can be attributed to the fact that (1) food comprises a decreasing proportion of household spending as incomes rise. and (2) the increase in technology which has led to the substitution of farm labour by various forms of capital.

description: In this paper we propose to study the world income distribution in the framework of Richard Stone-Richard Goodwin decomposition method [Goodwin, EJ 1949 and JPKE 1980, Stone¿s foreword to Pyatt-Roe, 1977]. The objective here is to collate the social accounting matrices of a group of nations with ROW treated exogenous and decompose the transactions matrix, in a common unit of account, to delineate effects of intra ('direct effects') country income disparity from inter ('cross effects') group income disparities. This decomposition is pertinent from the point of view of understanding whether the inter-regional income disparities are mainly mediated through the intra-regional income disparities implied by their structure of production and thereby assessing the impact of various growth policies on the macro structure of the economies.

description: The physics of the attractive one-dimensional Bose gas (Lieb-Liniger model) is investigated with techniques based on the integrability of the system. Combining a knowledge of particle quasi-momenta to exponential precision in the system size with determinant representations of matrix elements of local operators coming from the Algebraic Bethe Ansatz, we obtain rather general analytical results for the zero-temperature dynamical correlation functions of the density and field operators. Our results thus provide quantitative predictions for possible future experiments in atomic gases or optical waveguides.

description: We use a long series of annual data that span over 100 years to examine the relationship between output growth and output growth uncertainty in five European countries. Using the GARCH methodology to proxy output growth uncertainty, we obtain two important results: First, more uncertainty about output growth leads to a higher rate of output growth in three of the five countries. Second, output growth reduces output growth uncertainty in all countries except one. Our results provide strong support to the view that macroeconomists should examine the theories of economic growth and the variability of the business cycle in tandem.

description: Plasma instabilities can play a fundamental role in quark-gluon plasma equilibration in the high energy (weak coupling) limit. Early simulations of the evolution of plasma instabilities in non-abelian gauge theory, performed in one spatial dimension, found behavior qualitatively similar to traditional QED plasmas. Later simulations of the fully three-dimensional theory found different behavior, unlike traditional QED plasmas. To shed light on the origin of this difference, we study the intermediate case of two spatial dimensions. Depending on how the "two-dimensional'' theory is formulated, we can obtain either behavior.

description: Teams with a mix of gender produce more novel and higher-impact scientific ideas¹ and gender diversity leads to better science². But the systems in place tend to favour male researchers. We work to educate our colleagues on how to look at research projects and outputs through a gender lens. This means considering how gender roles, expectations, and stereotypes might affect people’s experiences, opportunities, and outcomes. It involves understanding the ways in which gender influences individuals, societies and research.

The recommendations in this brief hold tools to promote inclusive research, with the aim to empower researchers to work towards gender equality both on their own and in their teams and organisations. No team, individual, or even organisation can fix a broken system on their own – but together we are strong!
The solitons redistribution in Bose-Einstein condensate in quasiperiodic optical lattice

description: We numerically study the dynamical excitations in Bose-Einstein condensate (BEC) placed in periodic and quasi-periodic 2D optical lattice (OL). In case of the repulsive mean-field interaction the BEC quantum tunnelling leads to a progressive soliton's splitting and generating of secondary solitons, which migrate to closest trapping potential minima. A nontrivial soliton dynamics appears when a series of pi-pulses (phase kicks) are applied to the optical lattice. Such sudden perturbation produces a dynamic redistribution of the secondary solitons, leading to a formation of an artificial solitonic superlattice. Different geometries of OL are analyzed.

description: In this Letter, we use a general renormalization-group algorithm to implement Propp and Wilson's "coupling from the past" approach to complex physical systems. Our algorithm follows the evolution of the entire configuration space under the Markov chain Monte Carlo dynamics from parts of the configurations (patches) on increasing length scales, and it allows us to generate "exact samples" of the Boltzmann distribution, which are rigorously proven to be uncorrelated with the initial condition. We validate our approach in the two-dimensional Ising spin glass on lattices of size 64 x 64.

Design of decoupling control and time-delay compensation for a CFSTR
Creators: name: Chen, Liang
Publisher: name: University of British Columbia
Year: 2010

description: This thesis is concerned with the design of a decoupling compensator and a time-delay compensator for a nonisothermal continuous flow stirred tank reactor (CFSTR). An expression for the analysis of interaction of the two-variable CFSTR was theoretically derived by using the relative gain method (RGM). For the purpose of improving the stability of the decoupling control system, undercompensation for a decoupled CFSTR system was suggested and the robustness test of such undercompensation decoupler to the modelling error was studied. On the other hand, the proposed time-delay compensation method, unlike conventional Smith's scheme, can rely on the basic property of gain-invariant time-delay. The stability of this time-delay compensation method is not affected by the CFSTR control system time-variant time-delay, while its compensation structure has the same features as the Smith compensator. The design of a decoupler and that of a time-delay compensator are independent of each other. All compensation structures are physically realizable. The theoretical results are supported by simulation. Simulation results for a CFSTR demonstrate that the undercompensation decoupling control can tolerate a relatively wide modelling error and reduce the sensitivity of the CFSTR process to parameter variations and unwanted disturbances. Also, simulation results show that the proposed time-delay compensator can provide an improvement over the conventional Smith compensator.

description: Supersymmetry is assumed to be a basic symmetry of the world in many high energy theories, but none of the super partners of any known elementary particle has been observed yet. We argue that supersymmetry can also be realized and studied in ultracold atomic systems with a mixture of bosons and fermions, with properly tuned interactions and single particle dispersion. We further show that in such non-releativistic systems supersymmetry is either spontaneously broken, or explicitly broken by a chemical potential difference between the bosons and fermions. In both cases the system supports a sharp fermionic collective mode or the so-called Goldstino, due to supersymmetry. We also discuss possible ways to detect the Goldstino mode experimentally.

description: The objective of this paper is to examine the factors affecting both participation in an off-farm job and the number of hours worked off-farm by couples in farm households in an Irish region. Data from 278 farm households in Co. Mayo was analysed to this end. A multivariate examination of key characteristics, using cluster analysis, was carried out to classify households into different clusters. The analysis comes reasonably close to picking out the four regimes suggested by the presented theoretical model, that is a cluster in which neither the operator or spouse work off-farm, one in which only the spouse works off-farm, one in which only the operator works off-farm, and one in which both work off-farm. This analysis is followed by an econometric analysis of farm operator and spouse labour supply decisions. Both bivariate probit models and multivariate logit models are used to estimate the off-farm labour force participation of operators and spouses. The participation models are followed by estimations of off-farm hours of work supplied by the couple, using appropriate sample selection procedures. For operators, the driving characteristics influencing off-farm labour participation and hours supplied are farm and location characteristics. In contrast, family demographics and education level appear to influence off-farm labour participation and hours supplied by the spouse.

description: Hicks theorized about the trade cycle, from many perspectives, over the whole span of his long, fertile and distinguished profes- sional life. Beginning with thoughts on an equilibrium approach to the problem of the trade cycle in the early 30s, traversing1 those disequilibrium workhorses of macrodynamics, IS-LM and Multiplier- Accelerator models, he returned, in hunted hare fashion, to a Robert- sonian starting point. In this paper I attempt to construct a math- ematical tapestry of some of these Hicksian visions and vignettes, concentrating on (non-linear) trade cycle theories. I suggest that there are still pearls of analytical wisdom, on the non-linear dynam- ics of trade cycle theory, to be extracted from A Contribution to the Theory of the Trade Cycle (CTTC). The unlikely link between the way an economic conundrum, inherent in CTTC, was resolved and the resolution of (Part B of) Hilbert s 16th Problem for Liénard s equation is brie y mentioned.

description: Sample pretreatment process is usually performed before real sample detection. Extraction is one of the most prevalent pretreatment methods. Due to the unequal solubility in two liquid phases, target is extracted (usually from water to organic phase) and further detected with laboratory instruments. Although the analytical instruments have high sensitivity and selectivity, they are relatively expensive and require skilful hands, which is restricted to laboratory use. Here, paper-based analytical devices (μPADs) for measuring samples extracted with organic solvents were tested. The μPADs were employed as a filter for buffer exchange, allowing the transfer of targets from organic solvent to water-based buffer, which could be specifically detected by water-based assays. As an example, polychlorinated biphenyls (PCBs) in n-hexane were detected with aptamer and gold nanoparticles (AuNPs) on μPADs within 30 min. The result of colour change can be recognized from 70.0 ng/L with a low loading amount (0.5 μL). Instead of laboratory instrumental analysis with relative high cost, this assay showed the promising utility of μPADs for target detection after sample pretreatment, which could be utilized as a general platform for inexpensive onsite detection.

description: Bairamov et al. (Aust N Z J Stat 47:543-547, 2005) characterize the exponential distribution in terms of the regression of a function of a record value with its adjacent record values as covariates. We extend these results to the case of non-adjacent covariates. We also consider a more general setting involving monotone transformations. As special cases, we present characterizations involving weighted arithmetic, geometric, and harmonic means.

Influence of subsurface drainage and subirrigation practices on soil drainable porosity
Creators: name: Gao, Yuncai
Publisher: name: University of British Columbia

description: Subsurface drainage affects water table fluctuation patterns by removing the excess water from the soil. The annual average water table depths of the drained (A) and undrained (D) regimes are 0.83 and 0.48 m from the soil surface respectively. Subirrigation continuously provides water to the upper soil by capillary rise. The annual water table depths of the subirrigated regimes (B and C) are 0.61 and 0.70 m respectively. It is found that there is a significant curvilinear correlationship between the drainage flow rate and the water table height above the drain. Soil drainable porosity of different regimes was investigated by using the soil water balance approach. The average drainable porosity of regimes A and B are 6.0% and 4.9% from water table rise, and 5.9% and 4.5% from water table drawdown , respectively. Subirrigation adversely affects the soil drainable porosity. Soil drainable porosity is often considered as a constant. However, the results of this study indicate that it varies with the water table height above the drain. In the case of water table drawdown, this dependence can be successfully expressed by a negative exponential equation. In the case of water table rise, the correlation is not as significant, but there is still a trend that the drainable porosity decreases with the increase of the water table height above the drain. Evapotranspiration (ET) is often neglected in soil water balance models for the drain-able porosity determination. This may result in some errors. In this study, the potential ET rate was computed by the Penman and Hargreaves methods. These two methods give very similar ET values for the studied area. It is assumed that actual ET equals to the potential ET rate when the ground water table is close to the soil surface.

description: Το θέμα της διδακτορικής διατριβής αναφέρεται σε επιστρώσεις βασιζόμενες στο SiC με στόχο τη δημιουργία φραγμών οξείδωσης και διάχυσης και με προβλεπόμενες εφαρμογές στην Αεροναυπηγική. Για την παρασκευή των επιστρώσεων χρησιμοποιήθηκε η μαγνητικώς υποβοηθούμενη καθοδική ιοντοβολή στις ραδιοσυχνότητες (RF magnetron sputtering). Παρασκεύασθηκαν δύο κατηγορίες υμενίων SiC σε υποστρώματα Si: α) Λεπτά υμένια πάχους περίπου 120 nm και β) παχέα υμένια πάχους περίπου 300 nm. Τα υμένια SiC και ανεξάρτητα αλλά ταυτόχρονα τα υποστρώματά τους από Si οξειδώθηκαν στον αέρα στο θερμοκρασιακό εύρος 370 έως 1140 ºC και χαρακτηρίσθηκαν με φασματοσκοπία FTIR, ανακλαστικότητα νετρονίων (NR), ανακλαστικότητα ακτίνων Χ (XRR) και περίθλαση ακτίνων Χ σε μικρές γωνίες πρόσπτωσης (GID). Μελετήθηκε η εξέλιξη της δομής τους συναρτήσει της θερμοκρασίας και του χρόνου οξείδωσης. Yπάρχοντα μοντέλα στη βιβλιογραφία χρησιμοποιήθηκαν για την περιγραφή της κινητικής της θερμικής οξείδωσης του κρυσταλλικού Si και του άμορφου SiC στον αέρα. Υπολογίσθηκαν οι σταθερές οξείδωσης καθώς και οι ενέργειες ενεργοποίησης για τη διάχυση του οξυγόνου και τη χημική αντίδραση με το SiC και το Si και συγκρίθηκαν οι υπολογισθείσες τιμές με τις αντίστοιχες της βιβλιογραφίας.
description: The current PhD thesis refers to SiC based coatings in order to create oxidization and diffusion barriers with foreseen aerospace applications. Τhe SiC coatings were fabricated employing RF magnetron sputtering. Two main categories of SiC films were fabricated on Si substrates: a) Thin fiilms having a thickness of about 120 nm, b) Thick films having a thickness of about 300 nm. The SiC films and independently but simultaneously their Si substrates were oxidized in air in the temperatre range 370 to 1140 ºC and have been characterized with FTIR spectroscopy, neutron reflectivity (NR), X–Ray reflectivity (XRR) and grazing incidence diffraction (GID). The evolution of their structure was investigated as a function of oxidation temperature and time. Existing models in the literature were used for the description of the thermal oxidation kinetics of crystallized Si and amorphous SiC in air. The rate oxidation constants and the activation energies for diffusion and chemical reaction were determined and compared with the corresponding ones found in the literature.

description: In this paper we completely classify which graded polynomial R-algebras in finitely many even degree variables can occur as the singular cohomology of a space with coefficients in R, a 1960 question of N. E. Steenrod, for a commutative ring R satisfying mild conditions. In the fundamental case R = Z, our result states that the only polynomial cohomology rings over Z which can occur, are tensor products of copies of H^*(CP^\infty;Z) = Z[x_2], H^*(BSU(n);Z) = Z[x_4,x_6,...,x_{2n}], and H^*(BSp(n):Z) = Z[x_4,x_8,...,x_{4n}] confirming an old conjecture. Our classification extends Notbohm's solution for R = F_p, p odd. Odd degree generators, excluded above, only occur if R is an F_2-algebra and in that case the recent classification of 2-compact groups by the authors can be used instead of the present paper. Our proofs are short and rely on the general theory of p-compact groups, but not on classification results for these.

description: The ATLAS detector at CERN's Large Hadron Collider (LHC) will be exposed to proton-proton collisions from beams crossing at 40 MHz. At the design luminosity of 10^34 cm^-2 s^-1 there are on average 23 collisions per bunch crossing. A three-level trigger system will select potentially interesting events in order to reduce the read-out rate to about 200 Hz. The first trigger level is implemented in custom-built electronics and makes an initial fast selection based on detector data of coarse granularity. It has to reduce the rate by a factor of 10^4 to less than 100 kHz. The other two consecutive trigger levels are in software and run on PC farms. We present an overview of the first-level trigger system and report on the current installation status. Moreover, we show analysis results of cosmic-ray data recorded in situ at the ATLAS experimental site with final or close-to-final hardware.
