description: The level of earned incomes and renewal of fixed assets differed significantly among farms in the EU-25 group in years 2004-2006. The analysis of farms belonging to three biggest classes of economic size showed that abilities to self-finance reproduction, to reproduce fixed assets and to make gross as well as net investments were interdependant and were growing together with the growth of economic size of farms. The farms of size class (5) 40 - <100 ESU during the analysed period achieved simple reproduction of fixed assets. Only farms of size class (6) >=100 ESU enabled extended reproduction of fixed assets. The farms in size class (4) 16 - < 40 ESU accomplished only a narrowed reproduction of fixed assets. Decisions of farmers in the EU-15 group and in the new member states in the UE-10 group differed significantly. In the first group, although a surplus was achieved, it was not spent on self-financed investments and development. In the second group the level of earned surplus for self-financing determined investments and development. / Synopsis. Poziom wypracowanych dochodów oraz reprodukcji środków trwałych w gospodarstwach rolniczych krajów UE-25 w latach 2004-2006 był silnie zróżnicowany. Analiza gospodarstw rolnych z trzech największych klas wielkości ekonomicznej wykazała, że wskaźnik zdolności do samofinansowania reprodukcji, wskaźnik reprodukcji środków trwałych oraz wartość inwestycji brutto i netto były współzależne i rosły wraz ze wzrostem wielkości ekonomicznej gospodarstw. Gospodarstwa z klasy wielkości (5) 40 - <100 ESU w badanym okresie realizowały reprodukcję prostą środków trwałych. Tylko gospodarstwa z klasy (6) >=100 ESU wielkości zapewniały rozszerzoną reprodukcję środków trwałych. Gospodarstwa z klasy wielkości (4) 16 - <40 ESU zdolne były tylko do zawężonej reprodukcji środków trwałych. Zachowania inwestycyjne rolników z krajów UE-15 i nowo przyjętych krajów UE-10 wyraźnie się różniły. W pierwszej grupie mimo wypracowania nadwyżki nie była ona przeznaczana na samofinansowanie inwestycji i rozwoju. W drugiej grupie poziom wypracowanej nadwyżki na samofinansowanie warunkował inwestycje i rozwój.

Living and reliving the tension in one teacher’s life
Creators: name: Ediger, Krista Gayle
Publisher: name: University of British Columbia
Year: 2010

description: Whenever I’m in the classroom interacting with students, teaching and learning, I’m content. I’m also energised by planning, beginning with curriculum mapping, all the way through to the formatting of project guidelines/invitations. And yet, when I think about teaching as my career, I have a physical reaction, similar to the one I had in grade six when I lied to my parents so that I could go to a mixed party. I don’t feel noxious, but my stomach does tighten. There are reasons for this that I wanted to explore, so I decided to write to learn more about why I might feel the way I do. This in itself proved daunting given my insecurities and doubts about any knowledge I may have as a result of eight years teaching. I rail against the data-driven dialogue that is accorded so much value these days, and yearn for more stories, but am unsatisfied by my own. One of the themes that emerged during the writing of this paper was the importance of process. I’ve worked to make my classroom more process-oriented over the past two years. I place more emphasis on formative assessment and look for ways to move the focus away from the seemingly magnetic pull of tests, final projects and ultimately, report cards. I begin the process here of recognising that the tensions I feel with regard to evaluation (I worry that my having to assign grades negates any gains that may come from narrative feedback) and time (there’s not enough to teach the way I know I could with fewer demands) will never be resolved. I need to change in order to be more at peace with teaching. I also need to continue to search for ways out and through and around and in between the concerns I have because without some real work I believe that public education in British Columbia is going to become less vibrant and viable. I began looking for answers, but now reaiise that they’re much more valuable if they spawn more questions.

description: We have succeeded in synthesizing electron-doped polycrystalline bulk samples of T'-La1.8Eu0.2CuO4-yFy (y = 0 - 0.15) by the fluorination of undoped (Ce-free) T'-La1.8Eu0.2CuO4 using NH4F. The magnetic susceptibility measurements have revealed that the superconducting transition temperature, Tc, increases with increasing y, exhibits the maximum of 23 K at y = 0.025, and decreases. The dome-like dependence of Tc on the doped carrier concentration in the T'-type (La,Eu)-based cuprates is explained in terms of the pairing mediated by spin fluctuations based on the d-p model calculation [K. Yamazaki et al., J. Phys.: Conf. Ser. 871, 012009 (2017)].

description: Jazz pianists often uniquely interpret jazz standards. Passages from these interpretations can be viewed as sections of variation. We manually extracted such variations from solo jazz piano performances. The JAZZVAR dataset is a collection of 502 pairs of Variation and Original MIDI segments. Each Variation in the dataset is accompanied by a corresponding Original segment containing the melody and chords from the original jazz standard. Our approach differs from many existing jazz datasets in the music information retrieval (MIR) community, which often focus on improvisation sections within jazz performances. In this paper, we outline the curation process for obtaining and sorting the repertoire, the pipeline for creating the Original and Variation pairs, and our analysis of the dataset. We also introduce a new generative music task, Music Overpainting, and present a baseline Transformer model trained on the JAZZVAR dataset for this task. Other potential applications of our dataset include expressive performance analysis and performer identification.

description: We prove the emergence of spatially correlated dynamics in slowly compacting dense granular media by analyzing analytically and numerically multi-point correlation functions in a simple particle model characterized by slow non-equilibrium dynamics. We show that the logarithmically slow dynamics at large times is accompanied by spatially extended dynamic structures that resemble the ones observed in glass-forming liquids and dense colloidal suspensions. This suggests that dynamic heterogeneity is another key common feature present in very different jamming materials.

description: It is important to understand the dynamics of red blood cells (RBCs) in blood flow. This requires the formulation of coarse-grained RBC models that reproduce the hydrodynamic properties of blood accurately. One of the models that successfully reproduce the rheology and morphology of blood has been proposed by Fedosov et al. [D. A. Fedosov, B. Caswell, and G. E. Karniadakis, Comput. Methods Appl. Mech. Eng., Vol. 199, 1937-1948 (2010)]. The proposed RBC model contains several parameters whose values are determined either by various experiments or physical requirements. In this study, we developed a new method of determining the parameter values precisely from the fluctuations of the RBC membrane. Specifically, we studied the relationship between the spectra of the fluctuations and model parameters. Characteristic peaks were observed in the spectra, whose peak frequencies were dependent on the parameter values. In addition, we investigated the spectra of the radius of gyration. We identified the peaks originating from the spring potential and the volume-conserving potential appearing in the spectra. These results lead to the precise experimental determination of the parameters used in the RBC model.

description: We studied the magnetic field structures and dynamics of magnetized multiphase gas on parsec scales around supermassive black holes by using global 3D magnetohydrodynamics (MHD) simulations. We considered the effect of radiative cooling and X-ray heating due to active galactic nuclei (AGNs). The gas disk consists of a multiphase gas with (1) cold ($\leq 10^3$ K) and thin, and (2) warm ($\sim 10^4$ K) and thick components with a wide range of number densities. The turbulent magnetic energy at maximum is comparable to the thermal and turbulent kinetic energies in the turbulent motion. We confirmed that the turbulent velocity of the warm gas in the ambient cold gas is caused by magnetoconvective instability. The turbulent magnetic field due to magnetorotational instability (MRI) is developed in the disk, but the mean toroidal magnetic field dominates and supports in a quasi-steady state, where the plasma-$β$, the ratio between gas pressure and magnetic pressure, is low ($β< 1$). As often seen in adiabatic MHD simulations of rotating disks, the direction of the mean toroidal field periodically reverses with time even in multiphase gas structures. The direction reversal is caused by magnetic flux vertically escaping from the disk and by the combination of the MRI and the Parker instability.

description: We investigate an all-out optical setup allowing for generation of non-Abelian geometric phases on its large degenerate eigenspaces. The proposal has the form of an M -pod system and can be implemented in terms of integrated photonic waveguide structures. We show that by injecting a larger number of photons into the optical setup, the degeneracy of eigenspaces scales rapidly. After studying the spectral properties of our system for the general case, we show how arbitrary U(4) transformations can be generated on the dark subspace of an optical tripod filled with two photons. Moreover, a degeneracy in the bright subspaces of the system, absent in any atomic analogue, allows for the generation of universal single-qubit manipulations. Finally, we address the complexity issue of holonomic computation. Particularly, we show how two-qubit and three-qubit states can be implemented on a photonic tripod, where a natural multi-partite structure is inherited from the spatial mode structure of the waveguides.

description: We present the current status of our construction of synthetic spectra for type Ia supernovae. These properly take into account the effects of NLTE and an adequate representation of line blocking and blanketing. The models are based on a sophisticated atomic database. We show that the synthetic spectrum reproduces the observed spectrum of 'normal' SN-Ia near maximum light from the UV to the near-IR. However, further improvements are necessary before truly quantitative analyses of observed SN-Ia spectra can be performed. In particular, the inner boundary condition has to be fundamentally modified. This is due to the dominance of electron scattering over true absorption processes coupled with the flat density structure in these objects

title: Innovative Capabilities of the Agricultural Biotechnology Sector in Hungary
Creators: name: Huzair, Farah
Publisher: name: The Open University
Year: 2008

description: This study investigates how context-specific institutional factors affect innovative capabilities of the agricultural crop biotechnology sector in Hungary. Answering this question has involved three areas of research, into: the network of actors and its accommodation of technological characteristics; the sustained use of institutional arrangements which characterised the pre-transition science and innovation system; and, the difficulty of adapting to the regulatory environment in the post accession phase. The significance of this work results from the lack of current knowledge on the extent and survival of capabilities in this sector in Hungary. The study timing is also significant: This is a phase that demonstrates how the sector is surviving the economic crisis that accompanied transition and enduring the current political uncertainty surrounding national GM crop policy. The study uses qualitative methods, comprising a series of in-depth investigations. Data collection via interview and observation began in 2006. Data collection and analysis were guided by a theoretical framework emanating from national innovation systems and triple-helix perspectives. This thesis explores the challenges that are faced by an innovation system during economic transition. The thesis also contributes to the knowledge of science systems and how core science capabilities have contributed to the endurance of a sectoral innovation system. In conclusion the work finds that innovative capabilities in the Hungarian agri-biotech sector currently reside in the core competencies and activities of the science community in this sector and the networks they have created over time within and outside the country. Their future survival depends on the ability of the sector to adapt to the changing context. The institutions between actors and organisations are key to survival of capabilities and their ability to adapt. Institutions hold both the adaptive mechanisms for change and the legacies of the past which can help or hinder that change.

description: We study the semiclassical decay of macroscopic spinning strings in AdS_5 x S^5 through spontaneous splitting of the folded string worldsheet. Based on similar considerations in flat space this decay channel is expected to dominate the full quantum computation. The outgoing strings are uniquely specified by an infinite set of conserved (local) charges with a regular expansion in inverse powers of the initial angular momentum. We compute these charges and determine functional relations between them. Finally, a preliminary discussion of the corresponding calculation in the non-planar sector of the dual gauge theory is presented.

description: The EU Common Agricultural Policy creates great opportunities for the areas of Eastern Poland, mainly by means of promoting a change of its orientation towards the development of its multifunctionality. These processes must be accompanied by an increase of GDP stimulating an increase in consumption, because a wealthy society is always seeking safe, differentiated food and such food is produced by agriculture in the analyzed region. Such phenomenon may contribute to the development of small farms. Another trend of strategic development of agriculture in the region may rely on the prospects for situation in which the revenues from sales of public goods in form of a natural landscape and biodiversity values become comparable or exceed the revenues from sales of agricultural products. Such state of things in the region of Eastern Poland is possible in a short period of time. / Synopsis. Wspólna Polityka Rolna Unii Europejskiej stwarza szanse dla terenów Polski Wschodniej przez popieranie zmiany orientacji rozwojowej z rolniczej na wielofunkcyjną. Takiemu rozwojowi powinien towarzyszyć wzrost krajowego PKB, pociągający za sobą wzrost konsumpcji. Zamożne społeczeństwo będzie bowiem zawsze poszukiwać zróżnicowanej i bezpiecznej żywności. Taka żywność jest produkowana w analizowanym regionie. Drugi kierunek rozwoju regionu wiązać się może z sytuacją, w której sprzedaż dóbr publicznych, takich jak naturalny krajobraz czy bioróżnorodność, zaczną przynosić przychody większe niż sprzedaż produktów rolnych. Taka sytuacja może wystąpić w niedługim czasie w Polsce Wschodniej.

description: The balance of exploration and exploitation plays a crucial role in accelerating reinforcement learning (RL). To deploy an RL agent in human society, its explainability is also essential. However, basic RL approaches have difficulties in deciding when to choose exploitation as well as in extracting useful points for a brief explanation of its operation. One reason for the difficulties is that these approaches treat all states the same way. Here, we show that identifying critical states and treating them specially is commonly beneficial to both problems. These critical states are the states at which the action selection changes the potential of success and failure substantially. We propose to identify the critical states using the variance in the Q-function for the actions and to perform exploitation with high probability on the identified states. These simple methods accelerate RL in a grid world with cliffs and two baseline tasks of deep RL. Our results also demonstrate that the identified critical states are intuitively interpretable regarding the crucial nature of the action selection. Furthermore, our analysis of the relationship between the timing of the identification of especially critical states and the rapid progress of learning suggests there are a few especially critical states that have important information for accelerating RL rapidly.

description: We analyze four-lepton contact interactions that lead to lepton flavor violating processes, with violation of individual family lepton number but total lepton number conserved. In an effective Lagrangian framework, the assumption of gauge invariance leads to relations among branching ratios and cross sections of lepton flavor violating processes. In this paper, we work out how to use these relations systematically. We also study the consequences of loop-induced processes.

description: We present a nonlinear field theory of a three-sublattice hexagonal antiferromagnet. The order parameter is the spin frame, an orthogonal triplet of vectors related to sublattice magnetizations and spin chirality. The exchange energy, quadratic in spin-frame gradients, has three coupling constants, only two of which manifest themselves in the bulk. As a result, the three spin-wave velocities satisfy a universal relation. Vortices generally have an elliptical shape with the eccentricity determined by the Lamé parameters.

description: This paper looks at migration of Polish citizens in the context of intra-EU labour mobility. Since the 2004 EU enlargement Poland has become the main migrant-sending country in the region. Polish labour migration concentrates in the United Kingdom and Ireland which opened their labour markets right after Poland’s accession, as well as in Germany, which restricts access to its labour market for workers from Poland. The focus is on two branches f economy in which many Polish migrants work, i.e. agriculture and food processing. The study results suggest that in the three examined countries those industries are heavily reliant on migrant, especially seasonal, workers from the new EU member states. Polish migrant workers are of great importance to the German, Irish and British agriculture and food processing and they are in demand. They mitigate the effects of domestic labour shortages resulting from a low work status and wages significantly lower than in the other sectors of national economy. Important determinants of Polish workers recruiting in agriculture and food processing are also their relatively high work ethic, productivity and reliability when compared with those of domestic workers. / Synopsis. Artykuł przedstawia migracje obywateli polskich w kontekście mobilności siły roboczej w ramach UE. Po rozszerzeniu Wspólnoty w 2004 r. Polska stała się głównym krajem wysyłającym migrantów do innych państw regionu. Najważniejszymi miejscami docelowymi dla polskiej siły roboczej są Wielka Brytania i Irlandia, które otworzyły dla niej swoje rynki pracy w 2004 r., oraz Niemcy, wciąż utrzymujące restrykcje. Skupiono się na zatrudnieniu Polaków w rolnictwie i przetwórstwie spożywczym wymienionych krajów, gdzie ich obecność jest ważna i zauważalna. Wyniki badań sugerują, że zarówno produkcja rolnicza, jak też przetwórstwo żywności w tych krajach są w dużym stopniu uzależnione od podaży pracy oferowanej przez obywateli nowych krajów członkowskich UE. Polscy robotnicy odgrywają dużą rolę i są pożądani przez pracodawców w niemieckim, brytyjskim i irlandzkim sektorze rolno-żywnościowym. Przyczyniają się do złagodzenia niedoborów podaży rodzimej siły roboczej, wynikających z gorszego statusu zawodowego oraz znacznie niższego wynagrodzenia w porównaniu z innymi sektorami gospodarki narodowej. Ponadto, do kluczowych czynników determinujących popyt na pracę Polaków należą relatywnie wysoka etyka pracy, wydajność oraz solidność w porównaniu z krajowymi pracownikami.

description: In this paper we present an analysis to determine the existence of singularities in spatially homogeneous anisotropic universes filled with nonlinear electromagnetic radiation. These spaces are conformal to Bianchi spaces admitting a three parameter group of motions G$_3$. For these models we study geodesic completeness. It is shown that with nonlinear electromagnetic field some of the Bianchi spaces are geodesically complete, like G$_3$IX and G$_3$VIII; however, completeness depends on the curvature of the space. When certain topology is assumed, Bianchi G$_3$IX presents geodesics that are imprisoned. It is surprising that in the linear limit (Maxwell field) the spacetimes are singularity-free even if the curvature parameter is zero.

description: The work is presenting effects of three years of the sugar market reform. In six countries the sugar production has ceased, and in many, including Poland, it has been much limited. Simultaneously a group of countries emerged with greater production than before the reform. Even though retail prices of sugar went down it did not cause lowering prices of products containing sugar. In order to stay in the market, both sugar factories and farmers must reduce to minimum the production costs. / Synopsis. Praca przedstawia skutki trzech lat reformy rynku cukru. W sześciu krajach zaprzestano produkcji cukru, a w wielu, w tym Polsce, znacznie ją ograniczono. Jednocześnie wyodrębniła się grupa krajów o większej produkcji niż przed reformą. Mimo że zmalały ceny detaliczne cukru, to nie spowodowało to obniżenia cen wyrobów zawierających cukier. Aby utrzymać się na rynku, zarówno cukrownie jak i rolnicy, muszą maksymalnie ograniczać koszty produkcji.

description: This work presents the intake of financial support from the EU by poultry producers in Małopolska region against a background of other production directions in agriculture. Data about projects financed by the EU in farms in Małopolska were taken from the Agency of Agriculture Restructuring and Modernization. Farmers in Małopolska received support for investment in poultry production (in number of 10 projects) worth 1 618.79 thousand PLN, which accounts for less than 2% of the total value of realized investment projects in agricultural farms. In the area of facilitating the start for young farmers only 1 project (worth 50 thousand PLN) out of 531 realized projects was connected with poultry production. This accounts for 0.2% of the total amount (26 550 thousand PLN) awarded to young farmers in Małopolska. / Synopsis. W pracy przedstawiono wykorzystanie środków pomocowych z UE przez producentów drobiu w Małopolsce na tle innych kierunków produkcji rolniczej. Skorzystano z danych Małopolskiego Oddziału Regionalnego ARiMR, dotyczących informacji o projektach i zrealizowanych inwestycjach w gospodarstwach małopolskich, finansowanych ze środków unijnych. W Małopolsce pozyskano środki do finansowania inwestycji w produkcji drobiarskiej (w liczbie 10 zrealizowanych umów) na kwotę 1 618,79 tys. zł, co stanowi niecałe 2% łącznej wartości zrealizowanych projektów inwestycyjnych w małopolskich gospodarstwach rolnych. W zakresie ułatwienia startu młodym rolnikom tylko 1 (50 tys. zł) na 531 realizowanych wniosków dotyczył produkcji drobiarskiej. Jego wartość stanowiła 0,2% ogólnej kwoty (26,55 mln zł) przyznanej młodym rolnikom w Małopolsce.

description: Understanding how students construct abstract mathematical knowledge in classroom setting and the use of various instructional tools in facilitating such abstract constructions have been central themes in mathematics education research. This study used Abstraction in Context (AiC) as a theoretical framework to study studying high school students’ processes of constructing and justifying of central angle theorem in dynamic geometry environment. Data analysis revealed that the although the central angle theorem was proposed and verified through dragging and measuring tools enabled by a GeoGebra driven simulation, the need to produce a formal proof establishing its validity was not realized by the group, suggesting that the dragging and measuring features of the dynamics geometry environment may pose challenges for teacher and students to construct abstract formal proofs.

description: Laufende internationale Bestrebungen negative Umwelteinflüsse und Auswirkungen auf die Gesundheit zu bewerten, reduzieren und zu begrenzen haben dazu geführt dass auch Architektur und Bauindustrie einen immer wichtigeren Schwerpunkt auf Nachhaltigkeit legen. Um Architekten und Bauingenieure bei der Bewertung und Dokumentation der Umweltbelastungen währen des Lebenszyklus eines Gebäudes zu unterstützen, wurden in Folge dieses Prozesses Computer-Programme zur Lebenszyklusanalyse entwickelt. Diese Arbeit präsentiert einen Überblick über den Stand der verfügbaren Lebenszyklusanalyse-programme für den Baubereich. Die Gebrauchstauglichkeit einer Auswahl repräsentativer Arbeitshilfen aus verschiedenen Segmenten wird detailliert bewertet. In einer Fallstudie wird der Schwerpunkt der Betrachtung auf den Arbeitsprozess selbst und die Unterstützung bei der Entscheidungsfindung im Ablauf der architektonischen Entwurfsphase gelegt.
description: Along with international efforts to evaluate, reduce and limit negative impact on the environment as wells as detrimental effects on human health, architectural and construction industries started to put more their emphasis on sustainability. As a consequence Life Cycle Assessment (LCA) software tools have been developed to help design and construction professionals to evaluate and document the environmental impact of the life cycle of a building. This thesis aims to present a state of the art review on currently available buildingrelated LCA software tools. A range of representative software tools are thoroughly assessed with respect to usability. By this case study -based upon selected tools-, the work process of these software tools will be presented and how they guide and support the decision-making in design and architectural workflow.

description: Introduction Preserving patient dignity is an overarching tenet in palliative care. Though patient dignity and its multiple facets have been studied in Western societies, interpretations of dignity may change depending on the context influenced by socio-cultural, and political circumstances, ensuing in different meanings and implications. Aim To explore the interpretations of the concept of dignity perceived by patients with palliative care needs and family caregivers within the Lebanese context. Method 1. An integrative review to explore and synthesise evidence on the understanding of dignity in the Middle Eastern palliative care context. 2. A qualitative interview study with fourteen patients with palliative needs and fifteen family caregivers to understand how dignity is interpreted and preserved in illness. The data were analysed inductively using reflexive thematic analysis. The findings from the two groups of participants were compared against each other and with the Chochinov Model of dignity. Findings Most of the findings from the integrative review came from Iran. Seven themes were developed: Maintaining privacy and secrecy; Gentle communication to preserve hope for wellbeing; Financial stability and accessibility of medical supplies; Family Support; Physical Fitness; Reliable health care, and Social justice that endorses equal care to all. Patients’ and family caregivers’ interviews revealed four common themes about maintaining dignity: a) The importance of faith b) The need to preserve physical, social, and mental wellbeing c) The central role of family d) Compassionate health care. These findings were similar to the themes synthesised from the integrative review highlighting the impact of context in understanding dignity. When comparing the findings to the Chochinov Model of Dignity, preserving outer physical appearance, equitable and affordable care and health resources were two new subthemes that surfaced as necessary for maintaining dignity during illness. Faith and family support emerged as central findings anchoring patient dignity. On the other hand, Autonomy and Aftermath concerns, themes mentioned in the Chochinov Model, appeared to be of less importance in this participant group. Conclusion In contrast to Western countries, faith and family ties in Lebanon are central in understanding and maintaining dignity for patients with palliative needs. This study demonstrates that cultural values and the overall socio-economic and political environment shape patients’ interpretations of dignity, resulting in implications for policy, clinical practice, community initiatives, and education.

description: Any high-contrast imaging instrument in a future large space-based telescope will include an integral field spectrograph (IFS) for measuring broadband starlight residuals and characterizing the exoplanet's atmospheric spectrum. In this paper, we report the development of a high-contrast integral field spectrograph (HCIFS) at Princeton University and demonstrate its application in multi-spectral wavefront control. Moreover, we propose and experimentally validate a new reduced-dimensional system identification algorithm for an IFS imaging system, which improves the system's wavefront control speed, contrast and computational and data storage efficiency.
