description: In der vorliegenden Arbeit wurde untersucht, ob eine relativ kurzzeitige Intervention eines Konzentrationstrainings positive Veränderungen in der Aufmerksamkeit der Jugendlichen erzielen kann. Es nahmen insgesamt 24 Jugendliche im Alter von 15 bis 17 Jahren am Projekt teil. Acht Schülerinnen und Schüler mit erhöhtem Förderbedarf und/oder Symptomen einer Aufmerksamkeitsstörung wurden umfassender beobachtet. Im Zeitraum von Februar bis April 2017 wurde während zwölf Lektionen im A-B-A-B-Design an einem gezielten Konzentrationstraining gearbeitet. Dazu wurden Übungen und Arbeitsblätter aus dem «Marburger Konzentrationstraining» (Krowatschek & Wingert, 2007) verwendet. Im Vorher-Nachher-Vergleich konnte keine wesentliche allgemeingültige Verbesserung nachgewiesen werden. Es zeigten sich jedoch individuelle Fortschritte in der Aufmerksamkeit, der Merkfähigkeit und der Selbststeuerung.
title: The extinction of the rudist bivalves
Creators: name: Swinburne, Nicola Helga Margaret
Publisher: name: The Open University
Year: 1990

description: The rudist bivalves were one of the many and varied groups of organisms to be extinguished at the end of the Cretaceous Period. They were a group of bivalves which evolved during Late Jurassic times to dominate the carbonate shelves on the margins of the Tethys Ocean during the Cretaceous Period. Through Late Cretaceous times their diversity climbed to a peak and then entered a period of rapid decline, resulting eventually in the complete extinction of the group.

Theories as to the cause of that extinction should clearly be based upon a knowledge of the detailed pattern of the decline. Most important is the question of the timing of the extinction: How long did it take from the peak of diversity to the elimination of the entire group? Is there one main extinction event - or are there several - or is the pattern a gradual decline? In answering these questions this work adopts a new approach to dating end Cretaceous strata by using strontium isotope stratigraphy. The method works by measuring the 87Sr/86Sr of palaeo-seawater preserved in marine carbonate, such as the thick low-Mg calcite layer of rudist shells. The 87Sr/86Sr of seawater was changing fairly rapidly through time in the latest Cretaceous. The pattern of change has been established in detail using samples from Boreal sequences of which the ages are known with respect to the belemnite stratigraphy. Using this as a standard graph, Tethyan rudist samples have been dated by a comparison of the Sr isotope ratio.

The use of Sr isotope stratigraphy has enabled a time axis to be established, against which the ranges of rudist bivalves and of their facies have been ploued. From these data it can be clearly seen that the ranges of many of the established biostratigraphic markers are in error and that the stage boundaries, as defined by the belemnite and planktonic foraminiferal stratigraphies, are offset.

When the pattern of rudist diversity is plotted against this time scale it can be seen that, at a specific level, the rudists were at their most diverse at the Campanian/Maastrichtian boundary. Their decline lasted until I almost the end of the Maastrichtian after which the only survivors are Tertiary forms. The decline is related to the disappearance of rudist facies with the end Cretaceous regression, though that graph is slightly displaced from that of rudist diversity. This shows that the rudist extinction is not merely due to non-exposure of terminal Maastrichtian strata.
Gas phase methanol synthesis for carbon-11 radiopharmaceuticals
Creators: name: Van Lier, Erik
Publisher: name: University of British Columbia
Year: 2011

description: Carbon-11 radiopharmaceuticals are gaining an increasing importance in positron emission tomography due to their importance in diagnostic medicine. The most wide spread method of production of these radiopharmaceuticals is by methylation of an appropriate precursor with the highly reactive [¹¹C]methyl iodide. Conventional synthesis of this intermediate involves liquid phase synthesis of [¹¹C]methanol, which is the step that limits the specific activity of the final product. A catalytic gas phase methanol synthesis process was evaluated, that promises to avoid the loss of specific activity. In this procedure, [¹¹C]carbon dioxide produced in the target is first trapped and purified, then converted to [¹¹C]carbon monoxide using molybdenum and finally reduced to [¹¹C] methanol using a copper zinc oxide catalyst in the presence of hydrogen. In this study a device to trap and purify [¹¹C]carbon dioxide was developed and optimized. [¹¹C] Carbon dioxide produced in target was quantitatively trapped at -20° C on a carbon molecular sieve column and quantitatively released in less than 3.5 minutes. A reactor to convert 50 ppm carbon dioxide to carbon monoxide, based on the reaction with molybdenum, was developed. A commercially available process simulator was used to assist the optimization of operating conditions and molybdenum pretreatment methods. Under optimal conditions, carbon dioxide was converted to carbon monoxide with over 70% yield. A reactor to catalytically convert 50 ppm carbon monoxide to methanol was developed. A copper zinc oxide catalyst was prepared by a co-precipitation method. The catalyst was activated by reduction with hydrogen and passivated with compressed air prior to methanol synthesis. The effect of temperature, pressure and flowrate on the conversion of carbon monoxide to methanol were studied and results were used to create a kinetic model. This model was used to determine optimal operating conditions for this reactor and predicts 60% conversion of [¹¹C]carbon monoxide to [¹¹C]methanol. These findings suggest that gas phase [¹¹C] methanol synthesis is a viable alternative to the conventional liquid phase method, meriting further studies with carbon-11.

title: The role of metaphor in user interface design
Creators: name: Treglown, Mark
Publisher: name: The Open University
Year: 2002

description: The thesis discusses the question of how unfamiliar computing systems, particularly those with graphical user interfaces, are learned and used. In particular, the approach of basing the design and behaviour of on-screen objects in the system's model world on a coherent theme and employing a metaphor is explored. The drawbacks, as well as the advantages, of this approach are reviewed and presented. The use of metaphors is also contrasted with other forms of users' mental models of interactive systems, and the need to provide a system image from which useful mental models can be developed is presented. Metaphors are placed in the context of users' understanding of interactive systems and novel application is made of the Qualitative Process Theory (QPT) qualitative reasoning model to reason about the behaviour of on-screen objects, the underlying system functionality, and the relationship between the two. This analysis supports reevaluation of the domains between which user interface metaphors are said to form mappings. A novel user interface design, entitled Medusa, that adopts guidelines for the design of metaphor-based systems, and for helping the user develop successful mental models, based on the QPT analysis and an empirical study of a popular metaphor-based system, is described. The first Medusa design is critiqued using well-founded usability inspection method. Employing the Lakoff/Johnson theory, a revised version of the Medusa user interface is described that derives its application semantics and dialogue structures from the entailments of the knowledge structures that ground understanding of the interface metaphor and that capture notions of embodiment in interaction with computing devices that QPT descriptions cannot. Design guidelines from influential existing work, and new methods of reasoning about metaphor-based designs, are presented with a number of novel graphical user interface designs intended to overcome the failings of existing systems and design approaches.

description: The sign problem is a widespread numerical hurdle preventing us from simulating the equilibrium behavior of various problems at the forefront of physics. Focusing on an important sub-class of such problems, bosonic $(2+1)$-dimensional topological quantum field theories, here we provide a simple criterion to diagnose intrinsic sign problems---that is, sign problems that are inherent to that phase of matter and cannot be removed by any local unitary transformation. Explicitly, \textit{if the exchange statistics of the anyonic excitations do not form complete sets of roots of unity, then the model has an intrinsic sign problem}. This establishes a concrete connection between the statistics of anyons, contained in the modular $S$ and $T$ matrices, and the presence of a sign problem in a microscopic Hamiltonian. Furthermore, it places constraints on the phases that can be realised by stoquastic Hamiltonians. We prove this and a more restrictive criterion for the large set of gapped bosonic models described by an abelian topological quantum field theory at low-energy, and offer evidence that it applies more generally with analogous results for non-abelian and chiral theories.

description: The work examines Germany’s balance-of-payments surplus. The author first briefly considers the United States balance of payments. The German balance of payments is then analysed according to structural aspects, absorption, the level of domestic investment, and policy. A digression on stock-adjustment and flow models of international capital movements is also provided. The author concludes that absorption dominates the current-account balance, and that what is needed is well-functioning capital markets to fund the savings or borrowings which spill abroad, plus international coordination of monetary policy.

A comparison study of agricultural materials as carbon sources for sulphate reducing bacteria in passive treatment of high sulphate water
Creators: name: Brown, Amber
Publisher: name: University of British Columbia
Year: 2011

description: Several natural and agricultural organic materials were assessed as carbon sources for a potential passive sulphate reduction treatment system to treat lake and pond water containing high concentrations of sulphate for the purpose of creating drinking water for cattle. Of primary concern was that the system be low cost and simple to operate, since the end users would be farmers. Sediment removed from a low sulphate lake located near Kamloops, which contained a potentially highly active sulphate reducing bacteria (SRB) population was used in a mesocosm experiment to determine its effectiveness at supporting sulphate reduction. Originally operated as a continuous system, a flowrate of 6 mL min⁻¹ flushed the nutrients out of the system. While operating in batch mode, sulphate reduction was observed within the sediment, but not above in the water layer due to mass transfer limitations. Thus, recirculation of water through the sediment was required to increase the overall rate of sulphate-reduction. Four different agricultural materials; barley, molasses, hay, and silage, were supplied to a SRB inoculum and concentrated SO₄²⁻ water to test their effectiveness as nutrient sources. A 1:1 (wt) mixture of hay and silage showed the highest drop in SO₄²⁻ and achieved a maximum SO₄²⁻ reduction rate of 14.4 mg SO₄²⁻ L⁻¹d⁻¹. A second study, which tested the leachates of barley and orchard grass silages, found similar rates (19.4 ± 1.6 mg SO₄²⁻ L⁻¹d⁻¹). Based on this work, a pair of mesocosms were built and supplied with a mixture of silage and hay. These systems achieved initial maximum rates of 33.8 mg SO₄²⁻ L⁻¹d⁻¹. After a second sulphate addition the maximum rate increased to 132.4 mg SO₄²⁻ L⁻¹d⁻¹. The ΔSO₄²⁻ / ΔsCOD ratios were determined to be 1.10 and 0.91 g g⁻¹ for mesocosms A and B. A halt in sulphate reduction was concomitant with an increase in sulphide concentration to 323.5 mg L⁻¹. It is hypothesized that sulphide inhibition of the SRB occurred. Recycling the water through an aerobic treatment system containing sulphur-oxidizing bacteria, to oxidize the sulphide to sulphur, is one possible method to remediate these high sulphide levels.
title: Linking child care to infant attachment : what lies in-between?
Creators: name: Robinson, Alex
Publisher: name: The Open University
Year: 2000

description: Objectives: To investigate the relationship between maternal separation anxiety, hours in non-maternal child care and security of motherinfant attachment in early infancy.

Design: Prospective. Methods: The participants for this study were 67 mothers and their infants enrolled in a large scale prospective study. The first 100 women were sent a letter outlining the current study and requested to 'opt in'. Those mothers who agreed to participate completed the Maternal Separation Anxiety Scale (MSAS) when the infant was ten and seventeen months. The mother-infant attachment relationship was assessed according to the standardised Strange Situation Procedure when the infant was aged seventeen months (+/- two weeks). All other data were collected in the main study.

Results: Maternal Separation Anxiety was not predictive (alone or in combination with other variables) of attachment status. Significant differences in levels of separation anxiety were found between mothers who were and mothers who were not employed outside the home. Separation anxiety was also related to a number of variables, including the age of the infant when the mother planned to use non-maternal child care, the total hours of non-maternal child care, infant temperament and maternal sensitivity.

Conclusions: The non-significant results in the main analysis mean that no firm conclusions regarding a relationship between levels of maternal separation anxiety, hours in non-maternal child care and security of mother-infant attachment in infancy can be drawn. Future research (with a larger and more diverse sample) should continue to explore the concept of maternal separation anxiety in relation to a number of other variables, including maternal role preference and quality of child care, as it may hold important implications for social policy and preventative clinical work.

description: This study is an extension of two previous studies in which the authors build upon their model of trade union action on contract renewals. To this end, a distinction is made between the percentage of workers at any given moment of time whose new contracts take effect on or before the expiration date of their previous contract. The model is subjected to economic tests with data referring to the Italian industrial sector. The central conclusion is that, since with the wave of strikes initiated by the contract renewals of Fall 1969, the Phillips curve has shifted to the right and upwards and its slope for any given level of unemployment is nearly doubled with respect to the slope prevailing in the previous twenty years. Some implications concerning the present conditions of dynamic instability of the inflationary process are then highlighted. JEL: E24, E31, J51

description: We use a dynamical systems approach to analyse the tilting spatially homogeneous Bianchi models of solvable type (e.g., types VI$_h$ and VII$_h$) with a perfect fluid and a linear barotropic $γ$-law equation of state. In particular, we study the late-time behaviour of tilted Bianchi models, with an emphasis on the existence of equilibrium points and their stability properties. We briefly discuss the tilting Bianchi type V models and the late-time asymptotic behaviour of irrotational Bianchi VII$_0$ models. We prove the important result that for non-inflationary Bianchi type VII$_h$ models vacuum plane-wave solutions are the only future attracting equilibrium points in the Bianchi type VII$_h$ invariant set. We then investigate the dynamics close to the plane-wave solutions in more detail, and discover some new features that arise in the dynamical behaviour of Bianchi cosmologies with the inclusion of tilt. We point out that in a tiny open set of parameter space in the type IV model (the loophole) there exists closed curves which act as attracting limit cycles. More interestingly, in the Bianchi type VII$_h$ models there is a bifurcation in which a set of equilibrium points turn into closed orbits. There is a region in which both sets of closed curves coexist, and it appears that for the type VII$_h$ models in this region the solution curves approach a compact surface which is topologically a torus.

This uniform domain is obtained as a uniformization of a (Gromov) hyperbolic filling of $Z$. To do so, we construct a family of hyperbolic fillings in the style of the work of Bonk and Kleiner and the work of Bourdon and Pajot. Then for each parameter $β>0$ we construct a lift $μ_β$ of the doubling measure $ν$ on $Z$ to $X_\varepsilon$, and show that $μ_β$ is doubling and supports a $1$-Poincaré inequality. We then show that for each $θ$ with $0

title: You can't! The daily exercise of police authority in Rio de Janeiro : 1907-1930
Creators: name: Bretas, Marcos Luiz
Publisher: name: The Open University
Year: 1995

description: The police of Rio de Janeiro had an important role in the reform of the city in the early twentieth century. The impetus to build a modem city influenced elite intellectuals to try to reform the police in the modem, scientific fashion. After the first wave of reforms receded, the police was abandoned to a less prominent role, and left without resources to carryon the modernising process, resulting in the need to develop their own methods of work derived from their daily experience. The main purpose of this thesis is to look closely at daily police activity, trying to show how policemen developed their ways of viewing the world and their procedures from the experiences they faced. From their contacts with state administrators, in the figure of the Chief of Police, with members of the elite. and with the vast majority of poor citizens, policemen began to define the extent and limits of their power, building their place in the networks of patronage and authority that permeated Rio's society. They had to combine an unchecked power to deal with those they classified as the criminal classes, composed of the dispossessed, and an attitude of subservience to the powerful, in a pattern that characterises twentieth-century policing in Rio de Janeiro.

description: Coherence of developmental processes of the Polish farming and the food industry were assessed. This analysis covered dynamics of the evolution of production and demand, the value added of both incomes of the agricultural entrepreneur and the food processing industry worker and the agricultural prices, the food processing industry worker and the consumer. It was stated that there is a lack of coherence in the developmental processes of these two main elements of the food economy and lack of correlation between them. On the domestic (and local) scale the interlinks are weakening and their course does not confirm the often formulated thesis about the transfer of profits from farming to processing. This requires introducing phenomena of a global character into the research of developmental processes and the verification of many theses proposed earlier by agri-economic sciences.

description: The paper tackles the problem of making direct payments in the EU countries more equal. Two sets of indices and their evolution are being presented: payment rates per product and per hectare of eligible area. The need of redistribution of direct payments is being stressed, followed by the discussion on different scenarios of distribution among Member States. The model finally accepted by the EU institutions and Member States is presented, as well as calculations of shifts in per hectare rates due to direct payments redistribution. The results show increase of direct payments rate in Poland, but it is still slightly below the EU average.

We compare this direct calibration with the indirect procedure that must be adopted for a conventional capacitive level gauge. The device facilitates the correct adjustment of the 3He/4He fraction in the dilution refrigerator.

description: We consider agglomerates of misaligned, pressure supported tori orbiting a Schwarzschild black hole. A leading function is introduced, regulating the toroids distribution around the central static attractor-it enables to model the misaligned tori aggregate as a single orbiting (macro--)configuration. We first analyze the leading function for purely hydrodynamical perfect fluid toroids. Later, the function is modified for presence of a toroidal magnetic field. We study the constraints on the tori collision emergence and the instability of the agglomerates of misaligned tori with general relative inclination angles. We discuss the possibility that the twin peak high-frequency quasi-periodic oscillations (HF-QPOs) could be related to the agglomerate inner ringed structure. The discrete geometry of the system is related to HF-QPOs considering several oscillation geodesic models associated to the toroids inner edges. We also study possible effect of the tori geometrical thickness on the oscillatory phenomena.

description: The paper aims at assessment of the public funds support to investment activities of agricultural holdings and determination of how possible it was to fund the implemented investments without the state aid. The research was held in 2012 among 129 farms, which in 2004-2011 benefited from public financial aid in their investment activity. The selected farms were researched with the use of interview questionnaire concerning organisation of farms, obtained economic results and assessment of executed investments. To determine the possibilities of financing investments at researched farms without the public financial aid the linear programming method was used to develop models of farms, where public financial aid was replaced with commercial loan or own cash, if possible. It was decided that state aid in financing investments should be directed at farms likely to develop, which are not able to finance investments without state aid. Farms, which are too small to guarantee independent development in the future, and too large, which can gather up funds for investments without state aid, should be excluded from the support.
title: Creep behaviour of the ternary lead-free solder alloy : Sn-3.8wt.%Ag-0.7wt.%Cu
Creators: name: Cooper, Shellene
Publisher: name: The Open University
Year: 2002

description: Electronic equipment is facing the challenge of both miniaturisation and the need to replace lead in interconnections. In service, interconnections generally fail by thermomechanical fatigue, and this behaviour is strongly affected by the creep process. This thesis examines the creep behaviour of a popular lead-free replacement alloy, Sn-3.8wt.%Ag-0.7wt%Cu (Sn-Ag-Cu), in joint and bulk form. Experimental work involved the determination of the creep properties of this alloy at various temperatures, over a range of stresses. Over the regions tested, the creep behaviour is best described by the Norton power law constitutive equation. The stress exponent for bulk Sn-Ag-Cu ranged between 10 and 18 (at 125 to -lOoC respectively) and indicates that a dispersion-strengthened mechanism is dominant in the creep process. The activation energy for creep in the bulk Sn-Ag-Cu is approximately 120kJ/moi and falls in the region similar to that observed for the self-diffusion of tin. In joint form the stress exponent is greater than 10 at high stresses but a change in mechanism is indicated at lower stress where the creep exponent falls to 3. The activation energy for creep in Sn-Ag-Cu when used in joint form is approximately 70kJ/moi and falls in the region similar to that observed for the short-circuit diffusion of tin. Results obtained from the ternary alloy were directly compared to those from Sn- 37wt.%Pb (Sn-Pb) and other prospective lead-free alloys in bulk form. The creep resistance of the ternary lead-free alloy at 75°C is superior to the conventional Sn-Pb alloy and the possible replacement alloys (tin-copper and tin-silver). This superiority is retained when tested at similar homologous temperatures. However, the Sn-3.8Ag- O.7Cu alloy is less ductile but generally possesses strains to failure above 10 percent in comparison to the 25 to 50 percent ductility of Sn-Pb.

description: Finance in Italy over the past two decades is characterised by the contrast between the relative stability of the institutional structure of financial intermediaries on the one hand and the far-reaching changes in the instruments of monetary policy and even composition of credit flows, on the other. The present work examines certain aspects of the recent activities of financial intermediaries in Italy and takes stock of the present situation. The authors consider the increasing need for credit transformation, the institutional constraints, direct and indirect transformation, and other links between financial intermediaries. It is suggested that the disequilibria to be observed in the structure of the Italian capital market and credit institutions may simply reflect disequilibria in the non-financial institutions.

description: The paper, primarily, aims at presentation of the selected global and intra-European determinants of planning, running, updating and reforming the Common Agricultural Policy (CAP) of the European Union. These determinants form a dynamic system of interactions of complementary (synergies), but also contradictory (substitutability) character, with the addition of intrinsic dilemmas of the CAP, which are typical for each sectoral economic policy. Such a broad outlook is justified by the deepening interdependencies in the modern world and the significance of the EU as the largest economic player on the global scale. The CAP is continually at interest of other countries as a source of inspiration but also a precautionary tale as it comes to the undesired effects of widespread state interventionism. The paper is a cross-sectional study – though having some features of meta-analysis – which synthesises the works of other researchers and own thoughts of the author. All these deliberations led to the conclusion that the CAP – for years appealing to the paradigms of sustainability and multifunctionality of agriculture – bears features of a rather modern utilitarian construct oriented at the future. However, its strong dependence on subsidies makes it a rather unattractive proposal for most of the developing countries, even hindering the process of solving serious development problems. Furthermore, agricultural subsidies deform competition in the international agri-food markets. They also weaken the motivation of the EU farmers to try to improve their competitive position by entrepreneurial behaviours, imple-mentation of innovations, sound cost monitoring and adequate and flexible operating, financial and risk-management strategies.

description: Nell’articolo viene brevemente riesposto lo schema analitico utilizzato dal prof. D’Antonio. Successivamente , con l’aiuto di un esempio numerico, si mettono in evidenza le perplessità cui esso da luogo circa il significato dell’imputazione della pressione inflazionistica all’uno o all’altro comparto. Le perplessità vengono poi discusse analiticamente e si propone un metodo che consente di superarle. Tale metodo viene infine applicato ai dati dell’economia italiana.

description: We present adaptive optics high angular resolution ($\sim0\farcs$1) spectroscopic observations in the 3 $μ$m region of the Herbig Ae/Be star HD 97048. For the first time, we spatially resolve the emission in the diamond features at 3.43 and 3.53 $μ$m and in the adjacent continuum. Using both the intensity profiles along the slit and reconstructed two-dimensional images of the object, we derive full-width at half-maximum sizes consistent with the predictions for a circumstellar disk seen pole-on. The diamond emission originates in the inner region ($R \lesssim 15$ AU) of the disk.

description: Abstract Innovation strongly relates to successful business: growth, competitiveness, uniqueness, higher sales volumes, profitability, and higher market value. In their strive for growth, Small and Medium Enterprises often face serious challenges regarding the adoption of their innovations. While many ideas succeed and gain market share or even create new markets, other very promising innovations never reached the adoption threshold to make it on the mainstream markets. This constitutes a deep chasm that needs to be crossed for the company to fully leverage its technological competence and truly enjoy the fruits of innovation. Furthermore, today's knowledge intensive society, companies- boundaries become blurred and users expect tailored solutions to fit their individual needs. In this context, traditional business models like mass production prove insufficient for long term success, especially when the subject of innovation is High-Tech of a non-consumer type. In the present work a strategic framework is developed as enabler for High-Tech B2B SMEs to successfully cross the chasm to the mainstream market. The concept of Mass Innovation is introduced as synergetic combination of Open Innovation, Mass Customization and Duality oriented organization design. This is intended as empowering and dynamic infrastructure for those companies required to sell innovations rather than products, under the pressure of their customers. The necessary company capabilities are identified, as well as the success factors. The Mass Innovation strategic framework is exemplified on Photon, one company falling under the High-Tech B2B SME category. Photon is coming form the pure customizer side of the exploration-exploitation continuum, and is currently struggling to cross the chasm. A thorough analysis of the company, its capabilities and market is provided, and conclusions are drawn regarding the level of readiness of the organization and offerings for Mass Innovation. Clear suggestions and offered on how to improve the company-s capabilities and therewith performance.
Unione monetaria e politica di stabilizzazione nella Comunità Europea.

description: A plan for European Monetary Union was recently proposed based on the issue of a parallel European currency, the acceptance of which would be established by a market process, not by official edicts and which would be managed to achieve stable European-wide prices. This paper examines the desirability of, and problems associated with this particular approach. It represents yet a further attempt to show that the anti-union arguments are either wrong or they are positive, not normative propositions which lead to the prediction that union will not occur and do not lead to the prescription that it shouldn’t. The inflation records of the individual countries are first examined and the reasons for national differences in that rate are analysed. Then the implications of monetary union are analysed. Finally, the political objections to monetary union are considered. JEL: F36, F33

description: The sugar market in the EU is among the most regulated food markets in the world. This regulation is based on production quotas and foreign trade regulations. At the same time, individual links of the marketing chain are characterised by highly varied degree of concentration, which – in the conditions of strong market protection – creates the potential for monopolistic practices and the so-called monopolistic margins. In this context, the paper aims at empirical assessment of changes in sugar prices in Poland and identification of their determinants. The study was based on monthly sugar prices in Poland, the EU and across the world in 2000-2014. Time series models were used to assess correctness. The conducted research indicates that sugar production and prices in Poland and in the EU are largely determined by the market regulation system, while the sugar market reform had little effect on increasing the interrelations between the EU prices and world prices. At the same time, the retail and selling prices are strongly interrelated and these interrelations can be non-linear.

description: Entrepreneurial activity today requires new approaches in the formation and implementation of strategies for its development, which in the context of general macroeconomic instability is of particular relevance and requires an effective solution. Among these issues, the most acutely traced problems associated with changes in the marketing policy of enterprises, focused on the search and implementation of unconventional solutions. A special place in this process is given to benchmarking as a regular assessment of the quality process and business processes, along with comparison with the benchmark partners, will drive continuous improvement. Benchmarking is the process of identifying, researching, borrowing and adapting the best practices of enterprises in one industry, as well as enterprises in other industries, for the purpose of development.
Nuclear structure far from stability

description: Modern nuclear structure theory is rapidly evolving towards regions of exotic short-lived nuclei far from stability, nuclear astrophysics applications, and bridging the gap between low-energy QCD and the phenomenology of finite nuclei. The principal objective is to build a consistent microscopic theoretical framework that will provide a unified description of bulk properties, nuclear excitations and reactions. Stringent constraints on the microscopic approach to nuclear dynamics, effective nuclear interactions, and nuclear energy density functionals, are obtained from studies of the structure and stability of exotic nuclei with extreme isospin values, as well as extended asymmetric nucleonic matter. Recent theoretical advances in the description of structure phenomena in exotic nuclei far from stability are reviewed.

An experimental study of bubbles and droplets rising in a nematic liquid crystal

description: Liquid crystals are nature's beautiful examples of complex materials which are fundamentally fascinating. Their unusual properties have intrigued researchers from a wide variety fields including biologists, engineers, and even cosmologists. This thesis focuses on the dynamics of topological defects occurring near micro-droplets and micro-bubbles as they rise through an aligned nematic liquid crystal. The experiments were conducted in a fabricated flow-cell, and the observations were made using polarized light microscopy with the help of a motion control system. The results settle a controversy in the literature regarding the effect of hydrodynamic flow on the motion of defects by providing direct evidence of downstream convection of a Saturn ring defect and its transformation to a hyperbolic point defect. The point defect is convected further in the wake of the drop or bubble as the rising velocity increases. In equilibrium, both defect configurations may persist for long times. But the point defect sometimes spontaneously opens into a Saturn ring, indicating the latter as the globally stable configuration for the conditions used. A quantitative analysis of the rise velocities versus the location of defects yields graphs which are consistent with recent theoretical predictions. Besides these, we also observe interesting multiple drop and bubble interactions leading to the phenomenon of self-assembly and distorted defect structures.

subject: E31, E24, J31

description: The automatic adjustment of earnings to the cost of living usually had two objectives, to protect wages in whole or in part from the effects of inflation and to avoid a spate of destabilising wage claims. Recently, however, in Italy a third aim has been added, that of reducing the differences in remuneration. The present article looks at the experience and prospects of wage indexing in Italy, limiting the analysis to the sliding-scale in industry. The author first considers how wage indexing works in Italian industry. The average effectiveness of wage indexing is then examined. Finally, the specific effectiveness of the method of indexing related to the unified value of the point is analysed. JEL: E31, E24, J31
