Investment under risk tolerance constraints and non-concave utility functions: implicit risks, incentives and optimal strategies
Creators: name: Rodriguez-Mancilla, Jose Ramon
Publisher: name: University of British Columbia
Year: 2011

description: The objective of this thesis is to contribute in the understanding of both the induced behavior and the underlying risks of a decision maker who is rewarded through option-like compensation schemes or who is subject to risk tolerance constraints. In the first part of the thesis we consider a risk averse investor who maximizes his expected utility subject to a risk tolerance constraint expressed in terms of the risk measure known as Conditional Value-at-Risk. We study some of the implicit risks associated with the optimal strategies followed by this investor. In particular, embedded probability measures are uncovered using duality theory and used to assess the probability of surpassing a loss threshold defined by the risk measure known as Value-at-Risk. Using one of these embedded probabilities, we derive a measure of the financial cost of hedging the loss exposure associated to the optimal strategies, and we show that, under certain assumptions, it is a coherent measure of risk. In the second part of the thesis, we analyze the investment decisions that managers undertake when they are paid with option-like compensation packages. We consider two particular cases: • We study the optimal risk taking strategies followed by a fund manager who is paid through a relatively general option-like compensation scheme. Our analysis is developed in a continuous-time framework that permits to obtain explicit formulas. These are used first to analyze the incentives induced by this type of compensation schemes and, second, to establish criterions to determine appropriate parameter values for these compensation packages in order to induce specific manager's behaviors. • We consider a hedge fund manager who is paid through a simple option-like compensation scheme and whose investment universe includes options. We analyze the nature of the optimal investment strategies followed by this manager. In particular, we establish explicit optimal conditions for option investments in terms of embedded martingale measures that are derived using duality theory. Our analysis in this case is developed in a discrete-time framework, which allows to consider incomplete markets and fat-tailed distributions -such as option return distributions- in a much simpler manner than in a continuous-time framework.

description: Pandemia COVID-19 wywarła bezprecedensowy wpływ na działalność gospodarczą, kulturalną i społeczną, co miało znaczący wymiar przestrzenny. Zmiany w mobilności ogólnej, a w szczególności w migracjach wewnętrznych, były jednym z jej najbardziej powszechnie występujących przypadków. Wiele dotychczasowych badań analizowało różne aspekty wzorców mobilności wewnętrznej po wybuchu pandemii. Jednak niewiele badań skupiało się na obszarze Europy Środkowej i Wschodniej. Niniejsze badanie ma na celu wypełnienie tej luki poprzez określenie, jak intensywność i przestrzenne wzorce migracji wewnętrznych w EŚW zmieniły się między 2017 a 2022 rokiem, na przykładzie Polski. Pytamy, w jakim stopniu dominujące trendy migracji wewnętrznych (wyludnianie obszarów wiejskich i wzrost w obszarach metropolitalnych napędzany silnymi trendami suburbanizacyjnymi) zostały dotknięte podczas COVID-19 w porównaniu z latami poprzednimi. Wykorzystujemy dane z rejestru ludności dotyczące rocznych przepływów między gminami. Odkrywamy, że pandemia COVID-19 spowodowała spadek intensywności migracji w 2020 roku, jak również w latach następnych w porównaniu do lat 2017-2019, z niższymi wskaźnikami migracji netto na obszarach podmiejskich i wyższymi na obszarach peryferyjnych poza metropoliami.
description: The COVID-19 pandemic made an unprecedented impact on economic, cultural and social activity, which had a significant spatial aspect. Changes in mobility in general and in internal migration in particular were one of its most universally occurring instances. Many studies to date looked into various aspects of internal mobility patterns after the pandemic outbreak. However, little research has been focused on the area of Central and Eastern Europe. This study aims to fill that gap by determining how the intensity and spatial patterns of internal migration in CEE changed between 2017 and 2022, using the case of Poland. We ask to what extent the dominant internal migration trends (depopulation of rural areas and growth in metropolitan areas fuelled by strong suburbanization trends) were affected during COVID-19 compared to preceding years. We use population register data on annual flows between municipalities. We discover that the COVID-19 pandemic resulted in a decrease of migration intensity in 2020 as well as in the following years compared to 2017-2019, with lower net-migration rates in suburban areas and greater in non-metropolitan peripheries.

description: Hypoxic-ischemic encephalopathy (HIE) is associated with perinatal brain injury, which may lead to disability or death. As the brain is a lipid-rich organ, various lipid species can be significantly impacted by HIE and these correlate with specific changes to the lipidomic profile in the circulation. Objective: To investigate the peripheral blood lipidomic signature in dried blood spots (DBS) from newborns with HIE. Using univariate analysis, multivariate analysis and sPLS-DA modelling, we show that newborns with moderate-severe HIE (n = 46) who underwent therapeutic hypothermia (TH) displayed a robust peripheral blood lipidomic signature comprising 29 lipid species in four lipid classes; namely phosphatidylcholine (PC), lysophosphatidylcholine (LPC), triglyceride (TG) and sphingomyelin (SM) when compared with newborns with mild HIE (n = 18). In sPLS-DA modelling, the three most discriminant lipid species were TG 50:3, TG 54:5, and PC 36:5. We report a reduction in plasma TG and SM and an increase in plasma PC and LPC species during the course of TH in newborns with moderate-severe HIE, compared to a single specimen from newborns with mild HIE. These findings may guide the research in nutrition-based intervention strategies after HIE in synergy with TH to enhance neuroprotection.

description: Rising atmospheric carbon dioxide (CO2) concentration can change crop productivity directly by increasing photosynthesis, and indirectly by positive or negative modifications of growth responses to predicted global warming and changes in rainfall. The purpose of this experiment was to determine the effects of C02, temperature, soil type, and water table depth on growth of four cultivars of sugar cane, a C4 photosynthetic pathway species (Saccharum officinarum L.). Studies were conducted in paired temperature-gradient greenhouses at ambient and enriched levels of CO2 360 and ~ 710 μηιοί (CO2) mol"1 (air), respectively] with four temperature zones along the length of each greenhouse: baseline, +1.5, +3.0, and +4.5°C. These 1.5°C steps were maintained by a combination of heat inputs (electric heaters and sunlight) and ventilation by computer-controlled fans. Other treatments were soil type (mineral vs. organic), water table depth (constant water table of 20 cm vs. ~50-cm drained profile). The four cultivars were CP72-2086, CP73-1547, CP88-1508, and CP80-2086. Doubled C02 increased the following components of plant growth of the first sampling in late June-early July of 1997: leaf number = 7%; leaf area = 15%; leaf fresh weight = 13%; leaf dry weight = 8%; mainstem length = 32%; mainstem fresh weight = 31%; mainstem dry weight = 23%; juice volume = 40%; total fresh weight = 25%; juice dry weight = 36%; total dry weight = 21%. However, total fresh weight increase of that whole-crop harvest was somewhat less at 16%. Increasing temperatures caused a slight downward trend in sugar cane yield regardless of cultivar or CO2 treatment. The order of cultivar yields for the first harvest was: CP73-1547 > CP80-1827 > CP88-1508 > CP72-2086. Doubling C02 appeared to benefit sugar cane productivity more than the anticipated 10% increase for a C4 species. The apparent increase in sugar cane dry weight, fresh weight, and juice volume indicates greater yields as global atmospheric CO2 continues to rise.

description: The spin dynamics of photoexcited carriers in semiconductors in contact with a ferromagnet is treated theoretically and compared with time-dependent Faraday rotation experiments. The long time response of the system is found to be governed by the first tens of picoseconds in which the excited plasma interacts strongly with the intrinsic interface between semiconductor and ferromagnet in spite of the existence of a Schottky barrier in equilibrium.
Unified framework for generalized quantum statistics: canonical partition function, maximum occupation number, and permutation phase of wave function

description: Beyond Bose and Fermi statistics, there still exist various kinds of generalized quantum statistics. Two ways to approach generalized quantum statistics: (1) in quantum mechanics, generalize the permutation symmetry of the wave function and (2) in statistical mechanics, generalize the maximum occupation number of quantum statistics. The connection between these two approaches, however, is obscure. In this paper, we suggest a unified framework to describe various kinds of generalized quantum statistics. We first provide a general formula of canonical partition functions of ideal $N$-particle gases obeying various kinds of generalized quantum statistics. Then we reveal the connection between the permutation phase of the wave function and the maximum occupation number, through constructing a method to obtain the permutation phase and the maximum occupation number from the canonical partition function. In our scheme, the permutation phase of wave functions is generalized to a matrix phase, rather than a number. It is commonly accepted that different kinds of statistics are distinguished by the maximum number. We show that the maximum occupation number is not sufficient to distinguish different kinds of generalized quantum statistics. As examples, we discuss a series of generalized quantum statistics in the unified framework, giving the corresponding canonical partition functions, maximum occupation numbers, and the permutation phase of wave functions. Especially, we propose three new kinds of generalized quantum statistics which seem to be the missing pieces in the puzzle. The mathematical basis of the scheme are the mathematical theory of the invariant matrix, the Schur-Weyl duality, the symmetric function, and the representation theory of the permutation group and the unitary group. The result in this paper builds a bridge between the statistical mechanics and such mathematical theories.

description: The paper presents non-agricultural activity, in the context of selected activities in the new financial perspective of the RDP 2014-2020. Today, non-agricultural economic activities implies a gainful activity other than farming, but integrally connected with the farm. The RDP 2014-2020 actions related to non-agricultural activity were included in two cases as bonuses for start of non-agricultural activity and agricultural service development. Generally for that aim there were allocated EUR 478,9 million what meant 3,5% EFARD means. The number of farms realizing different kinds of activities than farming was on low level in relation to the total number of farms over 1 ha. In 2010 that hat number was 3.9% and fell to 2.6% in 2013.
title: The discourses of teaching and learning online

Publisher: name: The Open University
Year: 2010

description: This research investigates the discourses of e-learning and the way in which these discourses underpin the practices in the field. Having reviewed the relevant literature and looked at the teaching practices in two case studies, I propose that the collaborative learning discourse is very significant in e-learning, but that the didactic and institutional discourses, although not as immediately evident, are equally important in shaping the practices of online teaching and learning.

The intertextual nature of all texts, in particular the different voices found in the language of the tasks in the case studies, reveal that the practice associated with online teaching and learning draw on texts and voices from three discourses, collaborative learning, didactic and institutional.

Drawing on a Foucauldian perspective of discourse, the investigation of how the discourses operate at the level of practice makes it possible to look at the teaching and learning practices in the field of educational technology from a discursive perspective. In so doing, the historical and contextual perspectives embedded in the teaching and learning practices are taken into account, the aim being to understand the complexity and range of elements that help construct these practices.

Finally, the contributions of the study to the field are indentified, and some suggestions are made regarding the possible direction of future research.

description: The comparison of profitability of cultivation different varieties of starchy potato. Data was obtained from the owner of the farm who has signed a long-term contract and cooperated with the food industry enterprise ‘PEPEES’ in Łomża in the years 2012-2013. The highest marketable yield of starchy tubers was recorded in 2013 and was related to variety Kuras and the total production value per 1 ha in individual years was varied and ranged from 6,835.5 in the years 2013 in variety Sonda to 7,338.45 in the years 2012 in the same variety, and from 9,868.95 PLN in the years 2012 in variety Kuras, to 10,253.25 PLN in the years 2013. The income was highly variable in individual years depending on the yield level and the price per unit production. About the profitability of starchy potato cultivation decided direct costs. Seed potato and fuel costs accounted for the greatest proportion of the total costs. The most profitable variety of starchy potato was Kuras in 2013 .
Contextuality versus Incompatibility

description: Our aim is to compare the fundamental notions of quantum physics - contextuality vs. incompatibility. One has to distinguish two different notions of contextuality, {\it Bohr-contextuality} and {\it Bell-contextuality}. The latter is defined operationally via violation of noncontextuality (Bell type) inequalities. This sort of contextuality will be compared with incompatibility. It is easy to show that, for quantum observables, there is {\it no contextuality without incompatibility.} The natural question arises: What is contextuality without incompatibility? (What is "dry-residue"?) Generally this is the very complex question. We concentrated on contextuality for four quantum observables. We shown that in the CHSH-scenarios (for "natural quantum observables") {\it contextuality is reduced to incompatibility.} However, generally contextuality without incompatibility may have some physical content. We found a mathematical constraint extracting the contextuality component from incompatibility. However, the physical meaning of this constraint is not clear. In appendix 1, we briefly discuss another sort of contextuality based on the Bohr's complementarity principle which is treated as the {\it contextuality-incompatibility principle}. Bohr-contextuality plays the crucial role in quantum foundations. Incompatibility is, in fact, a consequence of Bohr-contextuality. Finally, we remark that outside of physics, e.g., in cognitive psychology and decision making Bell-contextuality cleaned of incompatibility can play the important role.

description: The observed near infrared background excess over light from known galaxies is commonly ascribed to redshifted radiation from early, very massive, PopIII stars. We show here that this interpretation must be discarded as it largely overpredicts the number of J-dropouts and Lyαemitters in ultra deep field searches. Independently of the detailed physics of Lyαline emission, J-dropouts limit the background excess fraction due to PopIII sources to be (at best) < 1/24. As alternative explanations can either be rejected (e.g. miniquasars, decaying neutrinos) or appear unlikely (zodiacal light), whereas the reality of the excess is supported by the interpretation of the angular fluctuations, the origin of this component remains very puzzling. We briefly discuss possible hints to solve the problem.

title: In Search of the Nigerian Pastoral: Nollywood and the Nigerian Creative-Industrial System
Creators: name: Bud, Alexander
Publisher: name: The Open University
Year: 2019

description: This thesis explores the Nigerian creative-industrial system through the window of Nollywood. It questions conventional models of development by suggesting an alternative approach inspired by the historiography of consumption-based industrialization. Involving over 200 interviews and an extended ethnographic investigation of set craftsmanship and house and-hotel film locations, the research was carried out in Lagos and Igboland. The study focuses on several core elements of the consumer-industrial system -- film and television; carpentry and fabrication; and houses and hotels; and engages with other parts such as events’ industries and printing and artizanal advertising. The structure reflects two trajectories in Nollywood production: location production in Igboland and the new studio-system in Lagos. In the first part, the ways in which Nollywood and the Igbo built environment have interacted to produce new kinds of space are explored. The second part considers how Nigerian techniques of material fabrication have developed to produce new styles in three main areas: furnishings, TV and film sets and promotional installations. The ability of these practices to extend in surprising directions, establishing economy-wide linkages in financing, sales promotions and event-marketing, is a key part of this analysis. In the conclusion, the themes are considered through the lens of the Nigerian Pastoral to illuminate the intertwined development of distinctive Nigerian styles and tastes and competitive industrial sectors.
Anisotropy of covert, endogenous orienting of attention across the visual field

Year: 2011

description: Are there advantages to voluntarily attending to some visual field locations over others? The work discussed here explores the question of whether covert, endogenous (voluntary) orienting to various visual field locations has anisotropic effects. Important to this question is understanding how paradigm parameters alter the way that attention is voluntarily distributed across possible target locations, and how that ultimately affects the anisotropy of performance at different visual field locations. When observers are cued to attend with 100% certainty to a visual field location, the effects of endogenous orienting run parallel to previous findings of perceptual and attentional anisotropy (vertical anisotropy; horizontal vs. vertical meridian). This is the first work to demonstrate an attentional benefit to voluntarily attending to the vertical meridian compared to the horizontal meridian. Lowering the cue's predictive value altered the pattern of anisotropic performance, revealing that attention had varying impact with distance from fixation, as well as a greater impact on the lower half of the vertical meridian. This result reflects how attention was distributed across possible target locations in the display, given that the target may not appear at the cued location. Further experiments showed that task parameters have a distinct effect on how attention is distributed across possible target locations. Altering the endogenous distribution of attention by eliminating or reducing an inhibitory gradient at fixation affects performance to the greatest degree close to fixation, and on the horizontal meridian. Both experiments are also the first to reveal an attentional oblique effect, whereby response time to targets presented on the intercardinal axes is consistently and significantly slower than on the cardinal axes. A key role is also demonstrated for the use of placeholders (perceptual objects) which facilitate the objects) which facilitate the voluntary distribution of attention across possible target locations. The effect of placeholders interacts with the cue's predictive value to alter how attention is voluntarily distributed across possible target locations. Overall, the answer to the overarching question is yes: covert, endogenous orienting has anisotropic effects. In light of these findings, four general guidelines are presented to illustrate the impact of covert, endogenous distribution of attention across the visual field.

title: Studies on Holkham salts hole : an isolated salt water community with relict features
Creators: name: Alcock, Barry R.
Publisher: name: The Open University
Year: 1982

description: There is at Holkham, North Norfolk, a marine pond which supports a fauna thought to be principally a relict from the time when it was part of an estuarine tideway, two hundred and fifty years ago. Studies have been carried out on the hydrology and hydrography of this pond, known locally as the Salts Hole. The nature of the substratum,changes in salinity, temperature and other physical variables have been assessed and from these it has been possible to establish that conditions within the pond are remarkably stable. The fauna is reviewed and its relationship to other brackish water ponds discussed. Experiments designed to produce response surfaces have been carried out for three crustacean species, Idotea chelipes, Gammarus duebeni and Praunus flexuosus. These describe how changes in salinity, temperature and oxygen concentration influence survival of both adults and juveniles. Populations drawn from the surrounding marshes of Holkham Bay have been compared to those of the pond,, The response surface centres of the Salts Hole populations correlate more closely with the conditions prevailing in the pond, than do the Bay populations. Electrophoresis of Malate dehydrogenase and Leucine aminopeptidase isozymes was performed for the same three species of crustaceans. The Salts Hole populations contain fewer alleles and show significantly higher levels of genetic divergence. Several hypotheses relating genetic polymorphism. and environmental conditions have been examined.The findings support Valentine's hypothesis of trophic resource stability and Stenseth's interpretation of the Red Queen hypothesis, predicting that fewer species are found in the pond than in the surrounding salt-marshes. The relative contributions of random genetic drift and selection are discussed and conclusions are drawn that the Salts Hole populations,despite their relatively short period of isolation and small numbers, have been subjected to the effects of selection.

description: Long cell protrusions, which are effectively one-dimensional, are highly dynamic subcellular structures. Length of many such protrusions keep fluctuating about the mean value even in the the steady state. We develop here a stochastic model motivated by length fluctuations of a type of appendage of an eukaryotic cell called flagellum (also called cilium). Exploiting the techniques developed for the calculation of level-crossing statistics of random excursions of stochastic process, we have derived analytical expressions of passage times for hitting various thresholds, sojourn times of random excursions beyond the threshold and the extreme lengths attained during the lifetime of these model flagella. We identify different parameter regimes of this model flagellum that mimic those of the wildtype and mutants of a well known flagellated cell. By analysing our model in these different parameter regimes, we demonstrate how mutation can alter the level-crossing statistics even when the steady state length remains unaffected by the same mutation. Comparison of the theoretically predicted level crossing statistics, in addition to mean and variance of the length, in the steady state with the corresponding experimental data can be used in near future as stringent tests for the validity of the models of flagellar length control. The experimental data required for this purpose, though never reported till now, can be collected, in principle, using a method developed very recently for flagellar length fluctuations.

description: The aim of the paper was to find the relation between the total, average and marginal productivity of human labour factor and the level of education of a farm manager. The study was based on micro-data from Polish FADN. The Cobb-Douglas function was used in the research. The impact of the level of education of the farm manager on the variation of labour productivity was estimated by investigating the relation between the total production (PLN) of the farm and aggregated production factors: labour input in AWU, agricultural land area (ALR), and fixed assets (PLN). The results of research show that the total, average and marginal productivity were higher in the sample of farms run by managers with higher education. This result indicates that the level of education of the farm manager has the significant impact on the efficiency of human labour management and shows the need for the farmers formal qualification improvement.

description: The paper aimed to present the energy growings as a source of raw material for the production of renewable energy in Poland. The data used come from secondary sources and covered the period 2011-2014. The were used quantitative and qualitative methods of analysis. It was found that the share of land used in Poland for energy purposes in 2012-2014 was about 4% of UAA. Their greatest area was occupied with plants, including rape, used in the production of bio-components which then are used in the production of transportation fuels. Components which are result of fuel production from grains are used in the production of animal feed. This area was therefore partly used for this reason. In 2011-2014, the production of esters and biogas steadily increased, whereas in 2014 the production of bioethanol was reduced. For the production of biogas, mainly agricultural byproducts and residues from agro-food industry are used, and so they do not compete for land with food products.

description: We study D-branes with plane waves of arbitrary profiles as examples of time-dependent backgrounds in string theory. We show how to reproduce the quantum mechanical (one-to-one) open-string S-matrix starting from the closed-string boundary state for the D-branes, thereby establishing the channel duality of this calculation. The required Wick rotation to a Lorentzian worldsheet singles out as 'prefered' time coordinate the open-string light-cone time.

title: Problems in Longterm Forecasting and Planning: with reference to transport and energy
Creators: name: Baker, Timothy Michael
Publisher: name: The Open University
Year: 1981

description: In this thesis I have set out my experiences of forecasting in the long term. (I have taken long term to be anything beyond 5 to 10 years). I have set forecasting in its context as a component of the planning process and have related the problems of forecasting to the ensuing problems in planning. The main areas I have covered are Transport and Energy, in a UK context.However I have touched on other fields and I expect the conclusions I have drawn about forecasting and planning to apply to many fields. The thesis is in two parts plus appendices. In the first part I report three substantial pieces of research. They illustrate many of the problems associated with forecasting, and I examine possible solutions to these problems. In the second part I describe how forecasts are made and some of the problems inherent in forecasting. I then examine why forecasts appear to be necessary in the planning/ policy making process. I conclude with the implications that my views on forecasting.

description: Issues related to the emission of harmful substances into the atmosphere are still very current theme and focusing the attention of representatives of scientific and political spheres. Implementation of many solutions aimed at reducing the release of these compounds in every sector of the global economy. Also in the agricultural sector actions made for this purpose. Particular attention should be paid to the issue of production technology considering greenhouse gas emissions in agriculture. EU farmers’ investment in modern machinery and adherence to the principles of cross-compliance and good agricultural practices have played an important role in reducing harmful emissions into the atmosphere. However, the risks associated with maintaining food security on a global scale will continue to significantly affect the level of intensity of use of natural resources by the agricultural sector, which will translate into the level of greenhouse gas emissions in this sector of the economy.
