Visitors’ evaluations of the historic content at Storyeum : an edutainment heritage tourist atraction
Creators: name: Hertzman, Emily
Publisher: name: University of British Columbia
Year: 2010

description: Edutainment heritage tourist attractions are a hybrid form of attraction that seeks to maximize both the educational value and entertainment value of their heritage contents through the use of multimedia and entertainment technologies. The edutainment nature of this new form of tourist attraction makes it increasingly difficult to distinguish it from other form of tourist attractions, such as museums of history and culture, theme parks and cultural performances, which may also work with the dual mandate of maximizing both educational and entertaining values. This thesis investigates how visitors understand and evaluate this new form of attraction. Interviews with visitors to Storyeum- an edutainment heritage tourist attraction that presents a theatrical musical history of the province of British Columbia- reveal that such attractions have the potential to generate within their visitors powerful feelings of pride in local identity, as well as other emotional responses. Visitors’ evaluations of Storyeum’s unique type of historical representations show a high degree of active and critical engagement with the attractions content. Visitors’ positive overall evaluations of Storyeum, their feelings of pride in local identity and their level of critical engagement with Storyeum’s historical representations are each discussed in detail in order to identify some general and potentially transferable characteristics of edutainment heritage tourist attractions.

description: Stanene, a two-dimensional counterpart to graphene, has the potential to exhibit novel quantum phenomena when grown on a magnetic topological insulator (MTI). This work demonstrates the formation of up to bilayer stanene on 30\% Sb-doped MnBi$_{2}$Te$_4$ (MBST), a well known MTI, albeit with a buffer layer (BL) in between. Angle-resolved photoemission spectroscopy (ARPES), when combined with density functional theory (DFT), reveals stanene related bands such as two hole-like bands and an inverted parabolic band around the $\overlineΓ$ point. An outer hole-like band traverses the Fermi level (\ef) and gives rise to a hexagonal Fermi surface, showing that stanene on MBST is metallic. In contrast, a bandgap of 0.8 eV is observed at the $\overline{K}$ point. We find that DFT shows good agreement with ARPES only when the BL and hydrogen passivation of the top Sn layer are considered in the calculation. Scanning tunneling microscopy (STM) establishes the honeycomb buckled structure of stanene. A stanene-related component is also detected in the Sn $d$ core level spectra, in addition to a BL-related component. The BL, which forms because of the chemical bonding between Sn and the top two layers of MBST, has an ordered crystal lattice with random anti-site defects. The composition of the BL is estimated to be Sn:Te:Bi/Sb $\approx$ 2:1:1 from x-ray photoelectron spectroscopy. Low energy electron diffraction shows that the lattice constant of stanene is marginally larger than that of MBST, and the STM result aligns with this. The BL bridges this disparity and provides a platform for stanene growth.

description: Im Juni 2014 wurde ein weltweit offener und anonymer Architekturwettbewerb für die Ideenfindung eines neuen Guggenheim Museums in Helsinki ausgeschrieben. Dieser stellt den Ausgangspunkt meiner Arbeit dar, von dem Teile der Auslobung, wie der Bauplatz sowie funktionelle und programmatische Punkte übernommen wurden. Das große öffentliche Bauwerke den Tourismus ganzer Städte und Länder beeinflussen können, auch bekannt als "Bilbao Effekt", erweist sich als große Bürde, Frank Gehrys gebautem Museum nacheifern zu müssen. Als Global Player hat die Guggenheim Stiftung in Verhandlungen mit Ländern und Städten dadurch enormen Rückenwind und kann etlichen finanziellen Druck auf Partnerstädte durch dieses Renommee ausüben. Kritisch hinterfragt wird die Notwendigkeit einer internationalen Organisation, die anstrebt, ähnliche Kunstrichtungen zu thematisieren und damit in Konkurrenz tritt mit bereits ansässigen heimischen Museen. Der Entwurf strukturiert das Südhafengebiet grundlegend um, ermöglicht eine neue Durchwegung der Stadt und dient als Erweiterung des öffentlichen Raumes am Wasser. Durch die relativ flache Ausgestaltung der Volumina nimmt das Museum Rücksicht auf die bestehende Stadtlandschaft und soll dazu einladen, sowohl im Inneren, als auch am Dach begangen zu werden.
description: In June 2014, an anonymous and open to the world architectural competition was called out in order to gain ideas for a new Guggenheim Museum in Helsinki. This competition, of which parts of the original competition brief, e.g. the building site, as well as functional and programmatic points were adopted, provided the starting point for my thesis. The fact that large public buildings can affect the tourism of entire cities and countries, known as the "Bilbao Effect", proves as a huge burden by having to follow the example of Frank Gehry's constructed museum. As a global player, the Guggenheim Foundation has an enormous power when negotiating with countries and cities and hence, can use its reputation to put a lot of pressure on its partner cities. The necessity of an international organisation, which aims at broaching the issue of similar art forms, thereby entering into competition with already established domestic museums, is critically scrutinized. The design at hand fundamentally restructures the south harbor area, allows for a new thoroughfare of the city and provides an extension of the public area on the waterside. By keeping the volumes relatively flat, the museum shows consideration for the urban landscape already present and shall invite visitors to explore not only the insides but also the rooftop.

description: Contracts are one of the main forms of the vertical transaction coordination. Key aspect of contractual relationships are adequate motivation and selection of partners. It can be done through a price mechanism. The theoretical concept applied for this kind of research is the principal–agent model (the agency theory). The main goal was to identify contract existing in transactions between producers’ organizations and agri-food sector. Consequently, the specific goal was to recognize the price formula in contracts. The research was focused on contracts signed in 2014 between groups operating on the potato market and their first buyers, so that is why the author has used the case study as the main research method, while the survey (collection of primary data) was conducted in the period March–May 2015 through the Computer Assisted Telephone Interview. The main first buyer of producers’ groups were processing plants. Almost all of groups used to sell their outputs through contracts. The fixed price was the most frequently used price formula in contractual relationship. / Synopsis. Kontrakty stanowią jedną z form pionowej koordynacji transakcji w agrobiznesie. Kluczowym aspektem umów jest odpowiednie motywowanie stron do właściwego działania oraz optymalny wybór kontrahentów. Może to się odbywać poprzez ustanowienie odpowiedniej formuły cenowej. Koncepcją teoretyczną umożliwiającą badanie tych problemów jest model pryncypał–agent w ramach teorii agencji. Celem głównym przeprowadzonych badań była identyfikacja powiązań kontraktowych między grupami producentów rolnych a pierwszym odbiorcą. Celem szczegółowym było rozpoznanie formuły cenowej. Przedmiotem badań były kontrakty między grupami producentów rolnych na rynku ziemniaka a pierwszym odbiorcą w 2014 r., dlatego zastosowano metodę studium przypadku, natomiast same dane zostały pozyskane w toku wspomaganego komputerowo wywiadu telefonicznego (w okresie marzec–maj 2015 r.).

description: This study presents a comprehensive numerical analysis of a full-scale horizontal-axis Floating Offshore Wind Turbine (FOWT) subjected to harmonic surging motions under both laminar and turbulent inflow conditions. Utilizing high-fidelity Computational Fluid Dynamics (CFD) simulations, namely Large-Eddy Simulation (LES) with Actuator Line Model (ALM), this research investigates the rotor performance, wake characteristics, and wake structures of a surging FOWT in detail. The study delves into the influence of varying inflow turbulence intensities, surging settings, and their interplay on the aerodynamic performance and the wake aerodynamics of a FOWT rotor. The results show that, through employing the phase-locking technique, Surging Induced Periodic Coherent Structures (SIPCS) can be identified in the wake of all the surging cases studied, irrespective of the inflow conditions and the surging settings. Additionally, the findings show that the faster wake recovery observed in the surging-laminar cases is not caused by facilitating instability-induced faster wake breakdown, a previously accepted hypothesis. Instead, it is the enhanced advection process resulting from the induction fields of SIPCS that causes the wake to recover faster. The analysis of rotor performance shows that the time-averaged rotor performances are affected by the intricate dynamics arising from the surging motions. With certain surging settings, the time-averaged thrust and the time-averaged power of a surging rotor are found to be simultaneously lower and higher compared to those of a fixed rotor. Furthermore, the study underscores the importance of considering both the magnitude of surging and the rate of surging ($\mathcal{V}$ and $\mathcal{W}$) simultaneously to fully characterize the hysteresis load on a surging rotor.

description: This dissertation examines the pathways to 100% renewable energy communities, including both electrical and cooking energy sources. By focusing in Sub-Saharan Africa, where only a tiny fraction of the population has access to electricity and biomass is still the overwhelming source of energy, the paper concerns itself with the concept of 'leap-frogging' carbon-based development. It outlines and assesses the existing literature on 100% renewable communities, before introducing a tailored model focused on Kasese District in south-west Uganda. Kasese District has set itself the bold target of using 100% renewable energy by 2020. By utilising the Long-Range Energy Alternatives Planning (LEAP) software, two scenarios (`Business-as-usual- and `potential-) are constructed to model progress in Kasese District from today through to 2025. These scenarios are outlined and their findings combined with knowledge found in the literature to produce a set of recommendations and identify bottle-necks in the process. Whilst the target of reaching 100% renewable energy in Kasese by 2020 is deemed highly unlikely, a set of policies theoretically implemented in 2016 to form the 'potential' scenario show how 100% renewable energy is possible in Kasese by 2025. These policies include maintaining the $5.5 USD per watt subsidy on solar panels, increasing access to finance for pico-power suppliers, investment in the harvesting of agricultural residues for use in cooking and the targeted afforestation of 10,000 hectares of deforested land in Kasese District. The results show that Kasese District has the potential to become an example of sustainable growth for the entire region, attracting both tourism and investment as it successfully decouples growth from carbon emissions and leap-frogs the `traditional- carbon-based development model.

description: Agricultural biomass is one of the major pillars for the supply of increasingly needed renewable resources for the growing bioeconomy. However, minimal additional pressure should be put on the environment. The approach of this thesis to interlink political frameworks and their objectives with those of the bioeconomy and the traits of hemp cultivation, processing and the scope of substitution is a genuinely new one. This thesis provides further genuinely new evidence and findings in regard to the inclusion of a hemp utilization scenario in the context of a EU bioeconomy. 1. The Material Flow Analysis can help to better understand, quantify and illustrate the "Hempland" scenario. Hence, a new approach with an adequate illustration of the flows and processes is incorporated. These are part of a scenario where multifunctional hemp is grown for its specific purpose in an average EU region. 2. Water is the most important mass flow in the system. Followed, by the sequestration and release of CO2 and O2. Besides, flue gas, waste and debris are crucial in the "Hempland" scenario. 3. In a EU average region with 10 million people, where 10% of the cropland is cultivated with hemp, the first harvest can contribute to the production of 1.48 Mt/year of biocomposites. Additionally 0.16 Mt/year of animal feed, 0.35Mt/year of insulation material and 1.38 Mt/year of hempcrete would result from this region. 4. The hemp crop is able to provide the bioeconomy with crucial amounts of sustainably produced biomass in order to cover quantities of demand of various productlines in the bioeconomy, without foiling the environmental objectives of the EWFD and the CAP. Against this background, the thesis has reveiled that the demand for composites and insulation material can be satisfied by far. About one third of the EU demand for soybean meal feed imports can be substituted. Also in regard to the respective EU concrete demand, more precisely the demand for non-load bearing concrete which was assumed to contribute 25% to the total demand for concrete, more than the half can in the long run be substituted by hempcrete.

description: Paralleling our recent computationally-intensive (quasi-Monte Carlo) work for the case N=4 (quant-ph/0308037), we undertake the task for N=6 of computing to high numerical accuracy, the formulas of Sommers and Zyczkowski (quant-ph/0304041) for the (N^2-1)-dimensional volume and (N^2-2)-dimensional hyperarea of the (separable and nonseparable) N x N density matrices, based on the Bures (minimal monotone) metric -- and also their analogous formulas (quant-ph/0302197) for the (non-monotone) Hilbert-Schmidt metric. With the same seven billion well-distributed (``low-discrepancy'') sample points, we estimate the unknown volumes and hyperareas based on five additional (monotone) metrics of interest, including the Kubo-Mori and Wigner-Yanase. Further, we estimate all of these seven volume and seven hyperarea (unknown) quantities when restricted to the separable density matrices. The ratios of separable volumes (hyperareas) to separable plus nonseparable volumes (hyperareas) yield estimates of the separability probabilities of generically rank-six (rank-five) density matrices. The (rank-six) separability probabilities obtained based on the 35-dimensional volumes appear to be -- independently of the metric (each of the seven inducing Haar measure) employed -- twice as large as those (rank-five ones) based on the 34-dimensional hyperareas. Accepting such a relationship, we fit exact formulas to the estimates of the Bures and Hilbert-Schmidt separable volumes and hyperareas.(An additional estimate -- 33.9982 -- of the ratio of the rank-6 Hilbert-Schmidt separability probability to the rank-4 one is quite clearly close to integral too.) The doubling relationship also appears to hold for the N=4 case for the Hilbert-Schmidt metric, but not the others. We fit exact formulas for the Hilbert-Schmidt separable volumes and hyperareas.

description: We study the statistics of the recurrence times between earthquakes above a certain magnitude M$ in California. We find that the distribution of the recurrence times strongly depends on the previous recurrence time $τ_0$. As a consequence, the conditional mean recurrence time $\hat τ(τ_0)$ between two events increases monotonically with $τ_0$. For $τ_0$ well below the average recurrence time $\ovτ, \hatτ(τ_0)$ is smaller than $\ovτ$, while for $τ_0>\ovτ$, $\hatτ(τ_0)$ is greater than $\ovτ$. Also the mean residual time until the next earthquake does not depend only on the elapsed time, but also strongly on $τ_0$. The larger $τ_0$ is, the larger is the mean residual time. The above features should be taken into account in any earthquake prognosis.

description: Energy has played an important role in China for achieving its impressive growth rates and the rapid industrialization of past decades. However, the cheap energy supply came from heavily polluting energy generation methods using fossil fuels, primarily coal. Severe pollution has made the Chinese energy regime highly unsustainable, with adverse effects on the environment and the health of the population. China has realised that a way to overcome this problem is the promotion of the utilization of renewable energy and the government has made their first efforts. Moreover, the country has to engage actively in ensuring energy security. Particularly, oil consumption is growing, which makes China increasingly dependent on oil imports, the prices of which can be at times volatile and unreliable. Also for this case, renewable energy promises to be a fruitful option. This thesis explores the capacities and possibilities the Chinese government has in renewable energy deployment and the environmental and economic benefits such a change would bring. Furthermore, decentralised energy, as the energy paradigm of the future, being highly economic and efficient, is analysed in the specific case of China. Moreover, flue gas treatment methods are presented, being indispensable in any case in the short-term perspective and being an important preliminary step to halt the deterioration of the already vulnerable environmental situation of the country.

description: The aim of this study is to show the differences in world production and consumption of meat (pork, beef and poultry) in the last decade, i.e. in 2003-2015.Within that period, the world production of those three main types of meat increased from 208.6 to 257.6 million tonnes, thus rising by 1.9% annually. The production of poultry meat recorded the highest annual growth (3.2%), with the production of pork increasing at a lower rate (by 1.7% annually), and the production of beef growing at the slowest pace, by only 0.6% annually. East Asia is the largest producer of pork (ca 53%), whereas the largest beef production is recorded in both Americas, accounting for ca ¼ of the world production each. Asia and North America are the leading producers of poultry meat (28.6 and 26.7% of the world production). Asia and the Commonwealth of Independent States (CIS) are regions with the highest meat deficit and, consequently, they are the largest importers of meat. Poland accounts for ca 1.6% of the world production of pork, beef and poultry meat, being the fourth largest meat producer in the European Union. Poland is a exporter nett beef and poultry meat and importer nett pork meat. / Synopsis.

description: Entanglement in a pure state of a many-body system can be characterized by the Rényi entropies $S^{(α)}=\ln\textrm{tr}(ρ^α)/(1-α)$ of the reduced density matrix $ρ$ of a subsystem. These entropies are, however, difficult to access experimentally and can typically be determined for small systems only. Here we show that for free fermionic systems in a Gaussian state and with particle number conservation, $\ln S^{(2)}$ can be tightly bound by the much easier accessible Rényi number entropy $S^{(2)}_N=-\ln \sum_n p^2(n)$ which is a function of the probability distribution $p(n)$ of the total particle number in the considered subsystem only. A dynamical growth in entanglement, in particular, is therefore always accompanied by a growth---albeit logarithmically slower---of the number entropy. We illustrate this relation by presenting numerical results for quenches in non-interacting one-dimensional lattice models including disorder-free, Anderson-localized, and critical systems with off-diagonal disorder.

description: Based on data collected by the CLEO III detector at CESR, we started a series of investigations to open the mysteries of the $Υ$(5S) resonance decay properties. $B_s$ mesons are expected to decay predominantly into $D_s$ meson, while the lighter $B$ mesons decay into $D_s$ only about 10% of the time. We exploit this difference to present the first evidence of a substantial production of $B_s$ mesons at the $Υ$(5S) resonance. We make here a preliminary model dependent estimate of the ratio of $B_s^{(*)}\bar{B}_s^{(*)}$ to the total $b\bar{b}$ quark pair production at the $Υ$(5S) energy to be $(21\pm 3 \pm 9)$%.

description: This paper addresses the general theme of conservation and/or change of heritage sites in urban and regional planning. The particular focus is on the management of UNESCO industrial World Heritage sites in Europe. Industrial heritage refers back to historic innovation and continues to be embedded today in innovation-orientated urban and regional development. The question that our study examines is: In which aspects does the management of an industrial World Heritage site coincide with (or differ from) that of areas of innovation? We identified criteria both for the management of industrial heritage sites (“Good Practice Wheel”) and areas of innovation (success factors for European Science and Technology Parks). In an online survey, we asked managers of heritage sites to evaluate management criteria. Completed survey responses were obtained for 22 of 38 European sites (58%) in 12 of 15 countries concerned (80%). Our study clearly shows an overlap of conservation and innovation priorities even in the management of UNESCO industrial World Heritage sites, and underlines the importance of integrative, “good” heritage management.

description: Engineered spin-electric coupling enables spin qubits in semiconductor nanostructures to be manipulated efficiently and addressed individually. While synthetic spin-orbit coupling using a micromagnet is widely used for driving qubits based on single spins in silicon, corresponding demonstration for encoded spin qubits is so far limited to natural silicon. Here, we demonstrate fast singlet-triplet qubit oscillation (~100 MHz) in a gate-defined double quantum dot in $^{28}$Si/SiGe with an on-chip micromagnet with which we show the oscillation quality factor of an encoded spin qubit exceeding 580. The coherence time $\textit{T}_{2}$* is analyzed as a function of potential detuning and an external magnetic field. In weak magnetic fields, the coherence is limited by fast noise compared to the data acquisition time, which limits $\textit{T}_{2}$* < 1 $μ$s in the ergodic limit. We present evidence of sizable and coherent coupling of the qubit with the spin states of a nearby quantum dot, demonstrating that appropriate spin-electric coupling may enable a charge-based two-qubit gate in a (1,1) charge configuration.
title: Dynamic Assessment of Academic Writing for Business Studies
Creators: name: Shrestha, Prithvi
Publisher: name: The Open University

description: This study explores the application of a formative assessment approach known as Dynamic Assessment (DA), as developed within the Vygotskian sociocultural theory of learning. DA blends instruction with assessment by targeting and further developing students’ Zone of Proximal Development (ZPD). The study investigates whether, and if so, how DA enhances students’ academic writing and conceptual development in business studies over time. DA and Hallidayan Systemic Functional Linguistics (SFL) informed the methodological design of this study, which employed a mixed methods approach in order to track learners’ ZPDs regarding academic writing development. The use of SFL to provide linguistic evidence for student writing development (ZPD) is new in DA and thus an innovative feature of this study. The data consists of six undergraduate business studies students’ three to four drafts of three assessments, which were analysed for textual and ideational meanings, as well as associated text-based interaction (mediation), complemented by student interviews and subject tutors’ written comments. This study extends previous DA studies such as Poehner and Lantolf (2005) in two key ways: i) its explicit focus on the construction of a macrogenre (whole text) as opposed to investigations of decontextualized language fragments, and ii) the range of mediational strategies identified and the consequent expansion of Poehner’s (2005) framework of mediation typologies. The findings suggest that DA, combined with SFL, provides insights into the learners’ maturing writing abilities, which the tutor can nurture further to help the learners internalise them. This study also shows that DA students made more gains than their non-DA counterparts regarding their ability to write a case study analysis genre. Additionally, the findings suggest that students can transfer their academic writing and conceptual knowledge from one assessment task to another, albeit at a varying level. The study, though small in scale, thus supports the view that targeted tutor support enhances students’ academic writing development. Implications are drawn concerning formative writing assessment research and practice in higher education.

description: We show that perturbations of a scalar field in the background of the black hole obtained with the Starobinsky-Bel-Robinson Gravity is unstable unless the dimensionless coupling $β$ describing the compactification of M-theory is small enough. In the sector of stability quasinormal spectrum show peculiar behavior both in the frequency and time domains: the ringing consists of two stages where two different modes dominate. The WKB method does not reproduce part of the spectrum including the fundamental mode, which is responsible for the first stage of the ringing. As a result, the correspondence between the high frequency quasinormal modes and characteristics of the null geodesics reproduces only one branch of the eikonal spectrum. The frequencies are obtained with the help of three methods (Frobenius, WKB and time-domain integration) with excellent agreement among them.

description: The main objective of this article is to assess the diversification of forestry function in European Union countries. Figures come from 2010 publications of Eurostat and the Central Statistical Office. The cluster analysis was made based on six forestry indicators (woodiness, forest area per inhabitant, the proportion of public ownership of forest, roundwood production, the proportion of plantations, the proportion of forests undisturbed by man). As a result researched countries were divided into five groups with different forestry characteristics. The analysis shows that forests in European Union countries have different functions (production and non-production), which is consistent with the concept of multi-functional forest, as well as the idea of sustainable development. / Synopsis. Głównym celem artykułu jest ocena zróżnicowania funkcji leśnej w krajach Unii Europejskiej. Dane liczbowe pochodzą z 2010 roku z publikacji Eurostatu i Głównego Urzędu Statystycznego. Na podstawie sześciu wskaźników z zakresu leśnictwa (lesistość, powierzchnia lasów na 1 mieszkańca, odsetek lasów własności publicznej, pozyskanie drewna, odsetek plantacji leśnych, odsetek lasów pierwotnych) przeprowadzono analizę skupień. W jej wyniku podzielono badane kraje na pięć grup o różnych cechach leśnictwa. Z przeprowadzonej analizy wynika, że lasy w krajach Unii Europejskiej pełnią różne funkcje (produkcyjne i pozaprodukcyjne), co wpisuje się w koncepcję lasu wielofunkcyjnego, a także w ideę zrównoważonego rozwoju.
title: An investigation into the role of professional learning on the online teaching identities of higher education lecturers

description: The economic, political and social climate in the UK has, in recent years, provoked some of the most profound changes to higher education since its inception in the Middle Ages. In addition, the pace of internet technologies and computer access has given rise to a far greater number of fully online courses offered by campus-based universities as well those, such as The Open University, which have traditionally offered a blend of online and face-to-face learning. But research reveals that adapting face-to-face and blended methods is challenging for higher education lecturers, particularly when teaching part-time or entirely remotely from their institutions. This three-year qualitative study investigates what type of professional learning contributes positively to the online teaching identities of part-time lecturers. Using a phenomenological, narrative approach it reveals what type of professional learning better equips lecturers for full online engagement and to what extent these needs are being met. It concludes with a series of recommendations for future development and professional learning which have relevance to all those who work in a fully online teaching environment.

description: Salinity intrusion caused by a rise in the sea level has adversely affected water utilization along rivers. One solution adopted by government agencies is to assign an appropriate river flow rate by utilizing a floodgate operation. Current floodgate operations rely on historical water drainage and operator experience, which lacks flexibility to respond to a fluctuating water supply. This paper proposed a framework using real options analysis (ROA) to create strategic alternatives to support decision-makers (DMs) regarding floodgate operational scheduling. The sea level was used to estimate the salinity intrusion distance and as a decision criterion. Apart from raising or lowering the floodgate, the ROA strategy may recommend to the DMs that they “wait-&-see” for a substantial sea-level change in the future and apply the “operate-as-before” approach in certain instances. The methods can be applied to a water discharge plan using separate floodgates in the same river basin or a dam.

description: The article contains an analysis of the volatility of production areas, production and procurement prices of selected species of berries fruits in Poland and in the world beetwen in the years 1992-2015. Variability analysis was conducted using the basic statistical measures, such as the area of variation, standard deviation, coefficient of variation. The direction and dynamics of prices determined on the basis of trends and chain and fixed base indexes. The analysis of empirical data showed that the prices of all the analyzed berries fruits increased in the years 1992 - 2015, but the greatest variability characterized by a purchase price of strawberries and black currants. / Synopsis. Artykuł zawiera analizę zmienności powierzchni, zbiorów i cen skupu wybranych gatunków owoców jagodowych w Polsce i na świecie w latach 1992-2015. Analizę zmienności przeprowadzono wykorzystując podstawowe mierniki statystyczne, takie jak: obszar zmienności, odchylenie standardowe, współczynnik zmienności. Kierunek i dynamikę zmian cen określono na podstawie tendencji oraz indeksów jednopodstawowych. Analiza danych empirycznych wykazała, że ceny skupu wszystkich analizowanych gatunków rosły w latach 1992-2015, ale największą zmiennością odznaczały się ceny skupu truskawki i czarnej porzeczki.

description: The aim of the paper was to assess the state of Polish food industry against the rest of the EU countries and the US based on the comparison of the degree of concentration of activities, labour productivity and selected structural features of this industry. The research is based on the data from the Statistical Office of the European Union (Eurostat) and the US Census Bureau which is part of the U.S. Department of Commerce. It was proved that in 2007-2014 the rate of growth of Polish food industry measured by an increase in turnover and value added in food processing sector was much higher than in the rest of the EU countries and the US. The progressive concentration of the food industry has led to the growth of labour productivity, giving a chance to improve its international competitive position. The branch structure of the food industry in Poland, viewed through the value of turnover, value added and employment, generally did not differ from the occurring in other EU countries and the US, being the largest producers and exporters of food in the world. / Synopsis. Celem artykułu była ocena stanu przemysłu spożywczego w Polsce na tle pozostałych krajów UE i USA w oparciu o porównanie stopnia koncentracji przedsiębiorstw, poziomu wydajności pracy oraz wybranych cech strukturalnych tego przemysłu. W badaniach wykorzystano dane Urzędu Statystycznego Unii Europejskiej (Eurostat) oraz agencji statystycznej Departamentu Handlu Stanów Zjednoczonych (US Census Bureau). Na podstawie przeprowadzonych analiz można stwierdzić, że w latach 2007-2014 tempo rozwoju polskiego przemysłu spożywczego mierzone wzrostem wartości obrotów i wartości dodanej w sektorze przetwórstwa żywności było znacznie szybsze niż w pozostałych krajach UE i USA. Postępująca koncentracja przemysłu spożywczego sprzyjała wzrostowi wydajności pracy, stwarzając szansę na poprawę jego międzynarodowej pozycji konkurencyjnej. Struktura branżowa przemysłu spożywczego w Polsce, rozpatrywana przez pryzmat wartości obrotów, wartości dodanej i zatrudnienia, zasadniczo nie odbiegała od występującej w pozostałych państwach UE i USA, a więc największych producentów i eksporterów żywności na świecie.
Momentum space spinning correlators and higher spin equations in three dimensions

description: In this article, we explicitly compute in momentum space the three and four-point correlation functions involving scalar and spinning operators in the free bosonic and the free fermionic theory in three dimensions. We also evaluate the five-point function of the scalar operator in the free bosonic theory. We discuss techniques which are more efficient than the usual PV reduction to evaluate one loop integrals. Our techniques can be easily generalised to momentum space correlators of complicated spinning operators and to higher point functions. The three dimensional fermionic theory has the interesting feature that the scalar operator $\barψψ$ is odd under parity. To account for this, we develop a parity odd basis which is useful to write correlation functions involving spinning operators and an odd number of $\barψψ$ operators. We further study higher spin (HS) equations in momentum space which are algebraic in nature and hence simpler than their position space counterparts. We use them to solve for three-point functions involving spinning operators without invoking conformal invariance. However, at the level of four-point functions, solving the HS equation requires additional constraints that come from conformal invariance and we could only verify that our explicit results solve the HS equation.
