description: Today many textbooks use the aggregate demand/aggregate supply analysis to convey the basics of Keynesian analysis of aggregate demand in conjunction with the profit maximisation postulate as characterising the aggregate supply side. However, this construction suffers from logical inconsistency, as the assumption of profit maximisation constraining firms through rising marginal costs of the ‘supply side’ is not easy to reconcile with the Keynesian postulate of output constrained by aggregate demand. This work follows a prominent line of reasoning to abandon the conventional AD curve altogether and replace it with a construct which seeks to remedy the inconsistency. This is achieved by assigning the central role to profit maximisation on the supply side, while the role of effective demand in the output determination is pushed to the background. JEL Codes: E12

title: Genome-wide association study of colorectal cancer using evolutionary computing
Creators: name: Geng, Shengkai
Publisher: name: Memorial University of Newfoundland
Year: 2021

description: The heritability of complex diseases is usually ascribed to interacting genetic alterations. Many diseases have been found that are influenced by genetic factors. Colorectal cancer (CRC) is a type of cancer starting from the colon or rectum that seriously threatens human health, and it has the chance to spread to other parts of the human body. The cause of CRC is multifactorial, including age, sex, intake of fat, etc. In addition, it has been suggested that genetic factors also play an essential role. Several genetic variations have been identified as associated with CRC. However, they only explain a small portion of the heritability. More advanced computational techniques are required to identify combinations of genetic factors. Recently, artificial intelligence algorithms have became a powerful tool for biomedical data analyses. In this thesis, I design an evolutionary algorithm for the identification of combinations of genetic factors, i.e., single nucleotide polymorphisms (SNPs), that can best explain the susceptibility to CRC.

description: Wigner functions are broadly used to probe non-classical effects in the macroscopic world. Here we develop an orbital-free functional framework to compute the 1-body Wigner quasi-probability for both fermionic and bosonic systems. Since the key variable is a quasi-density, this theory is particularly well suited to circumvent the problem of finding the Pauli potential or approximating the kinetic energy in orbital-free density functional theory. As proof of principle, we find that the universal functional for the building block of optical lattices results from a translation, a contraction, and a rotation of the corresponding functional of the 1-body reduced density matrix, indicating a strong connection between these functional theories. Furthermore, we relate the concepts of Wigner negativity and $v$-representability, and find a manifold of ground states with negative Wigner functions.

subject: E42, F33

description: The author reviews the disastrous history of the international monetary system. Since the end of World War II total world reserves have exploded and their distribution over time between countries has tended towards imbalance rather than away from it. An important reason is found in the role of dominant system currencies. The overvaluation of such currencies allows the issuing governments to behave irresponsibly; for instance the world's richest country, the United States, is currently also the world's biggest debtor. Such is the intellectual consensus but changing such a system is difficult, not least because current political systems have allowed it to occur. However, the end of the cold war and EMS offer new ways forward. JEL: E42, F33

The main objective of the project is the construction of physical work, including land, with equipment and relevant infrastructure, according to guidelines and standards of operation that provides a trail of its kind, i.e. Federal Inspection, framed both Act as official health standards, in the State of Mexico and nationally. According to the embedded content throughout the document, the trail project presents commercial viability or market, as to the existence of a local and regional unmet beef and pork, as well as marketing conditions and consumer prices appropriate to the study area. In addition, the project is technically feasible, because the location and size were considered optimal, engineering and production process are viable, well established organization and legal framework. On the financial side, the total estimated initial investment was 53.5 million pesos, 83.7% is tangible, intangible 0.1%, 1.7% and 14.6% contingency as working capital. The operating cost per unit produced and/or sold is less than the selling price for each product (beef and pork), which is indicative of profitability. The breakeven analysis indicated that required to produce and/or sell services 240 (maquilas and selling channels), equivalent to 2.6 million dollars per year to the total cost of production equals the total sales revenue. The horizon of the project planned trail, went to 10 years, with an initial total investment of 53.5 million pesos (MDP) and an annual EBITDA of 43.1 MDP. The project evaluation indicated that a minimum acceptable rate of return (MARR) of 12%, the project is paid completely, nine months and 18 days and will generate a cumulative operating profit (VAN) in its useful life, MDP 102.6, representing an Internal Rate of Return (IRR) of the investment, 77.1% and a True Profitability Rate (TPR or IRRM) of 30.9%. The actual trail project profitability is 65.1%, so you have no risk of losses. Under the conditions raised, the trail project will not cause damage to the environment, human, animal, vegetable or look down. Therefore, the results obtained, execution or implementation, resource management via pre institutions, state and federal agricultural order is suggested

title: Cultural and social capital in university choice : intra-class differences amongst working-class students in a sixth form college
Creators: name: Woodward, Philip John
Publisher: name: The Open University
Year: 2013

description: Background: Research on the way that sixth-form students utilise cultural and social capital when applying to university has suggested that students make differential choices on the basis of social class. Research has also highlighted the significance of intra-class differences amongst middle-class students. It suggests the extent to which family, school, peers, and the media may influence and impact on choices.

Aim: This research examines the extent to which students from similar socio-economic backgrounds, and in particular 'working-class' students, make choices. This process is examined in terms of the university and course choices made and associated social advantage and prestige.

Methods: This research employs an interpretative paradigm using qualitative methods and a conceptual framework derived from Bourdieu. Focus groups and semi-structured interviews were used to investigate research questions and a grounded approach to data analysis was utilised.

Findings: Findings suggest that access to cultural and social capital is limited to familial influence. Students were influenced by their parents in differential ways, but also drew on the experience of their siblings.However, it was noted that the college environment had a limited impact on student decisions. When making choices the most notable themes linked to general locality, where respondents were fairly polarised in their desire to 'stay local' or 'move away'.

Discussion and Conclusions: Locational preference linked to degree of geographical cultural knowledge and led to the development of a new theoretical concept that I term locational capital. This corresponded to intentions to avoid certain locations such as 'the rural' or 'the provincial' and provides a new way of understanding choice. These geographical constructions, linked to perceptions concerning Higher Education Institutions, often triggered concerns regarding 'fitting-in' and 'social class' and for many resulted in limitations on choice. This imposed a limitation on applying to prestigious HEIs.

title: Early county chief constables in the north of England 1880-1905
Creators: name: Leigh, Juliet Esme
Publisher: name: The Open University
Year: 2013

description: This thesis assesses the authority of nineteenth-century chief constables through a study which was based in four northern counties. It challenges the frequently made generalisation that they were powerful and autonomous men whose relationship with the police authorities was close and amicable. The first section investigates the office holders themselves, their backgrounds, characters, reputations and the circumstances of their administration. It estimates their professional standing while they were supervised by Quarter Sessions. The focus then shifts to an exploration of the potential effects of the implementation of the 1888 Local Government Act on the independence of county chief constables. Subsequent chapters examine chief constables' autonomy after Standing Joint Committees took over police supervision, firstly in their control of industrial disruption and then in their day to day management of the force. The core of the enquiry is contained in accounts of how some chief constables were undermined by members of Standing Joint Committees who made direct attempts to deprive them of their authority. However, in contrast, the thesis also outlines the ways in which they benefited from their communication with Her Majesty's Inspectorate of Constabulary and the Home Office. The thesis concludes with a review of how sources of evidence have contributed to a more complete picture of the authority of the chief constables in the study.

description: Terahertz vortex beams with different superposition of the orbital angular momentum $l={\pm}1$, ${\pm}2$, ${\pm}3$, and ${\pm}4$ and spin angular momentum $σ={\pm}1$ were used to study antiferromagnetic (AFM) resonances in TbFe$_3$(BO$_3$)$_4$ and Ni$_3$TeO$_6$ single crystals. In both materials we observed a strong vortex beam dichroism for the AFM resonances that are split in external magnetic field. The magnitude of the vortex dichroism is comparable to that for conventional circular dichroism due to $σ$. The selection rules at the AFM resonances are governed by the total angular momentum of the vortex beam: $j=σ+l$. In particular, for $l={\pm}2$, ${\pm}3$, and ${\pm}4$ the sign of $l$ is shown to dominate over that for conventional circular polarization $σ$.

description: Recent theoretical predictions for low metallicity massive stars predict that these stars should have drastically reduced equatorial winds (mass loss) while on the main sequence, and as such should retain most of their angular momentum. Observations of both the Be/(B+Be) ratio and the blue-to-red supergiant ratio appear to have a metallicity dependence that may be caused by high rotational velocities. We have analyzed 39 archival Hubble Space Telescope Imaging Spectrograph (STIS), high resolution, ultraviolet spectra of O-type stars in the Magellanic Clouds to determine their projected rotational velocities V sin i. Our methodology is based on a previous study of the projected rotational velocities of Galactic O-type stars using International Ultraviolet Explorer (IUE) Short Wavelength Prime (SWP) Camera high dispersion spectra, which resulted in a catalog of V sin i values for 177 O stars. Here we present complementary V sin i values for 21 Large Magellanic Cloud and 22 Small Magellanic Cloud O-type stars based on STIS and IUE UV spectroscopy. The distribution of V sin i values for O type stars in the Magellanic Clouds is compared to that of Galactic O type stars. Despite the theoretical predictions and indirect observational evidence for high rotation, the O type stars in the Magellanic Clouds do not appear to rotate faster than their Galactic counterparts.

title: "Margiad Evans : body, book and identity : an analysis of the novels and autobiographical texts"
Creators: name: Caesar, Karen
Publisher: name: The Open University
Year: 2013

description: This thesis sets out to find Margiad Evans (1909-1958) in her works. To this end it offers an analysis of her four novels, her autobiographical texts, both published and unpublished, and her private writing, including letters and journals. Benefiting from insights drawn from autobiographical and psychoanalytic theory, the thesis explores the relationship between the life and the work and illuminates the various processes by which Evans uses the raw material of her experiences to create and recreate an identity. This resulting self is multi-faceted and shifting, but a continuing thread is her aim to construct for herself the identity of writer. Writing, therefore, becomes a perfonnative act creating and reinforcing the desired identity. This thesis explores the significance of the body in Evans's texts: she not only perceives body as text but also intuits how the text might come to stand for the suffering body. The latter, the need of the writer to construct herself through language, becomes acute for Evans as her body fails and motivates the writing of her two pathographies. A Ray of Darkness (1952) is one of the first of its examples of the genre. I also demonstrate the various ways in which Evans's texts can be read in the light of the history of Modemism. I explore the way shifting borders and identities are portrayed in the texts, as well as their self reflexive concern with their own production and the blurring of the distinction between fiction and autobiography. The thesis shows the continuity and development of Evans's personal therapeutic ideology of writing through all her texts. Evans's subject is always herself, but crucially herself as an author intimately and passionately involved in the process of writing.

description: The application of Artificial intelligence for teaching and learning in the academic sphere is a trending subject of interest in the computing education. ChatGPT, as an AI-based tool, provides various advantages, such as heightened student involvement, cooperation, accessibility and availability. This paper addresses the prospects and obstacles associated with utilizing ChatGPT as a tool for learning and assessment in undergraduate Computer Science curriculum in particular to teaching and learning fundamental programming courses. Students having completed the course work for a Data Structures and Algorithms (a sophomore level course) participated in this study. Two groups of students were given programming challenges to solve within a short period of time. The control group (group A) had access to text books and notes of programming courses, however no Internet access was provided. Group B students were given access to ChatGPT and were encouraged to use it to help solve the programming challenges. The challenge was conducted in a computer lab environment using PC2 environment. Each team of students address the problem by writing executable code that satisfies certain number of test cases. Student teams were scored based on their performance in terms of number of successful passed testcases. Results show that students using ChatGPT had an advantage in terms of earned scores, however there were inconsistencies and inaccuracies in the submitted code consequently affecting the overall performance. After a thorough analysis, the paper's findings indicate that incorporating AI in higher education brings about various opportunities and challenges.

A star by star comparison is made with MACHO and OGLE II photometries based on both variable and constant stars in common, and the transformation relationships to our photometry are provided. The pulsation properties of the RR Lyrae stars in the sample are discussed in detail. Parameters of the Fourier decomposition of the light curves are derived for the fundamental mode RR Lyrae stars with complete and regular curves (29 stars). They are used to estimate metallicities, absolute magnitudes, intrinsic (B-V)o colours, and temperatures of the variable stars, according to Jurcsik and Kovacs (1996), and Kovacs and Walker (2001) method. Quantities derived from the Fourier parameters are compared with the corresponding observed quantities. In particular, the "photometric" metallicities are compared with the spectroscopic metal abundances derived by Gratton et al. (2004) from low resolution spectra obtained with FORS at the Very Large Telescope.

description: We investigate the spatial clustering of X-ray selected sources in the two deepest X-ray fields to date, namely the 2Msec Chandra Deep Field North (CDFN) and the 1Msec Chandra Deep Field South (CDFS). The projected correlation function w(r_p), measured on scales ~0.2-10 h^-1 Mpc for a sample of 240 sources with spectroscopic redshift in the CDFN and 124 sources in the CDFS at a median redshift of z~0.8, is used to constrain the amplitude and slope of the real space correlation function xi(r)=(r/r0)^-gamma. The clustering signal is detected at high confidence (>~ 7 sigma) in both fields. The amplitude of the correlation is found to be significantly different in the two fields, the correlation length r0 being 8.6 +- 1.2 h^-1 Mpc in the CDFS and 4.2 +- 0.4 h^-1 Mpc in the CDFN, while the correlation slope gamma is found to be flat in both fields: gamma=1.33 +- 0.11 in the CDFS and gamma=1.42 +- 0.07 in the CDFN (a flat Universe with Omega_m=0.3 and Omega_L=0.7 is assumed; 1 sigma Poisson error estimates are considered). The correlation function has been also measured separately for sources classified as AGN or galaxies. In both fields AGN have a median redshift of z~0.9 and a median 0.5-10 keV luminosity of L_x~10^43 erg s^-1, i.e. they are generally in the Seyfert luminosity regime. As in the case of the total samples, we found a significant difference in the AGN clustering amplitude between the two fields, the best fit correlation parameters being r0=10.3 +- 1.7 h^-1 Mpc, gamma=1.33 +- 0.14 in the CDFS, and r0=5.5 +- 0.6 h^-1 Mpc, gamma=1.50 +- 0.12 in the CDFN. Within each field no statistically significant difference is found between soft and hard X-ray selected sources or between type 1 and type 2 AGN. (abridged)

description: We express the number of anti-invariant subspaces for a linear operator on a finite vector space in terms of the number of its invariant subspaces. When the operator is diagonalizable with distinct eigenvalues, our formula gives a finite-field interpretation for the entries of the $q$-Hermite Catalan matrix. We also obtain an interesting new proof of Touchard's formula for these entries.

description: The Segment Anything Model (SAM) is the first foundation model for general image segmentation. It has achieved impressive results on various natural image segmentation tasks. However, medical image segmentation (MIS) is more challenging because of the complex modalities, fine anatomical structures, uncertain and complex object boundaries, and wide-range object scales. To fully validate SAM's performance on medical data, we collected and sorted 53 open-source datasets and built a large medical segmentation dataset with 18 modalities, 84 objects, 125 object-modality paired targets, 1050K 2D images, and 6033K masks. We comprehensively analyzed different models and strategies on the so-called COSMOS 1050K dataset. Our findings mainly include the following: 1) SAM showed remarkable performance in some specific objects but was unstable, imperfect, or even totally failed in other situations. 2) SAM with the large ViT-H showed better overall performance than that with the small ViT-B. 3) SAM performed better with manual hints, especially box, than the Everything mode. 4) SAM could help human annotation with high labeling quality and less time. 5) SAM was sensitive to the randomness in the center point and tight box prompts, and may suffer from a serious performance drop. 6) SAM performed better than interactive methods with one or a few points, but will be outpaced as the number of points increases. 7) SAM's performance correlated to different factors, including boundary complexity, intensity differences, etc. 8) Finetuning the SAM on specific medical tasks could improve its average DICE performance by 4.39% and 6.68% for ViT-B and ViT-H, respectively. We hope that this comprehensive report can help researchers explore the potential of SAM applications in MIS, and guide how to appropriately use and develop SAM.

description: We study the electronic structure of the recently discovered diluted magnetic semiconductor Ga$_{1-x}$Cr$_{x}$N ($x$ = 0.01-0.10). A systematic study of the changes in the $occupied$ and $unoccupied$ ligand (N) partial density of states (DOS) of the host lattice is carried out using N 1$s$ soft x-ray emission and absorption spectroscopy, respectively. X-ray absorption measurements confirm the wurtzite N 2$p$ DOS and substitutional doping of Cr into Ga-sites. Coupled changes in the $occupied$ and $unoccupied$ N 2$p$ character DOS of Ga$_{1-x}$Cr$_{x}$N identify states responsible for ferromagnetism consistent with band structure calculations.

description: Pineapple is second only to citrus in the quantum of fresh fruit produced in Trinidad and Tobago. In 1994, the total land area in Trinidad under pineapple production was approximately 60 hectares. In Tableland, south Trinidad, approximately 250 hectares were cultivated in the year 2000. The rapid expansion in land clearing for increased pineapple cultivation continued and in 2004, approximately 470 hectares in Tableland are cultivated with pineapple. This lucrative crop, if sold at the present retail price of TT$2.25 per kilogram, can contribute about TT$19 million to the economy per annum. (TT$6.25 = US$1.00). The main production areas are established on heavy clays on sloping lands that are not ideally suited for pineapple growing. There is indiscriminate land clearing with no reference to slopes, soil or soil movement. Proper land preparation on the slopes is difficult, with accompanying problems of heavy run-off, water logging problems, land slippage, and erosion. The slow growing nature of the plant, the wide spacing used and reliance on persistent herbicides, applied at high rates, exposes the soil to the elements with disastrous consequences. As it exists, the resources are being degraded through non-sustainable practices. Fruit quality is less than optimum due to improper fertilizer usage and poor harvest and post harvest practices. Annual gluts are experienced and market possibilities through processed products have not been explored. This paper outlines strategies being undertaken by various institutions to promote pineapple production in a sustainable manner, such that all stakeholders in the commodity chain can continue to earn a livelihood in the medium and long term.

description: The work reviews the post-war history of the rules vs discretion debate. The focus is principally on theoretical developments which came to have a bearing on the debate. With the central figure of the debate being, without a doubt, M. Friedman, much of the huge literature centres around arguments first raised by him. Hence, special attention is paid to his contributions. JEL: B22

description: Passionfruit (.Passiflora edulis) is a local tropical fruit used in juice, jelly and ice cream in St. Croix. However, almost all of the juice used for making passion fruit drinks comes from imported concentrate. A field trial was developed to evaluate fifteen passion fruit varieties of red, yellow and red/yellow hybrids in the US Virgin Islands. The passion fruit vines were grown on either a single wire or three wire trellis system. All varieties tended to produce within nine months, with production peaking in October-November. Productioh was greater for some varieties on the three-wire trellis system than a single wire system. During the first two years, multiple varieties were lost due to lack of tolerance to high pH, calcareous soils and St. Croix's climatic conditions. 'Noel's Special', a yellow selection from Hawaii, had a deep orange pulp and was a consistent producer. The fresh juice or all varieties was in a range between pH 2-3. Four varieties: 'Noel's Special', 'Panama Gold', 'Rainforest', and 'TWZ hybrid' are recommended for passion fruit growers. A single-wire trellis system can be as productive as a three-wire system and provide the added advantage of lower installation cost and wind tolerance.
Dynamic and incapsulating processes in the generation of the world demand
Creators: name: BIASCO, S.
Publisher: name: PSL Quarterly Review
Year: 2013
Subjects: subject: Business cycle, demand, output, income growth
subject: F44, E32

description: The work argues that since the seventies the international economy has oscillated between two kinds of flow structures, one reflected in the upswing and the other in the downswing. In both cases, the international economy suffered, although in different ways, from the disappearance of some of the “safety valves” that had made it possible during the fifties and sixties for ex ante incongruities to be resolved without impeding the generation and transmission of output and income growth. Dealing with the stylised facts, the author brings out similarities in flow structures and in the corresponding adjustment problems recurring in the cycle. The author concentrates on relationships which have influenced the industrial part of the world, and examines them in a systemic approach covering the entire network of world connections.

description: In my article I woud like to find answers for the question how frequently and effectively the region’s business leaders in Northern Hungary participated in various development programs, as regards investments in health tourism, what developments have been made mainly in the area, what the positive effects of these developments were in the life of businesses, whether the businesses (leaders) feel successful, and how their success was manifested. I carried out a questionnaire survey among enterprises. From the data I calculated mean, SD and spectrum and examined the crosstab correlations as well, and the Cramer’s V associate coefficient and Contingency coefficient. The results of the correlation tests could be summarised as the following: According to the survey, the number of the medium-sized enterprises being involved utilised a significant proportion of their development funds, compared to the micro and small enterprises. Although the idea of spas winterizing their pools was not considered an important development, both the adventure and wellness elements were important for the construction of thermal baths. In the case of hotels, the expansion of wellness elements and other additional services together with the development of marketing activities played an important role. Besides the positive business publicity, enterprises see the positive effects of the investment in the increase of their income; the success can be the result of the adequate supply of components, the professional management and that of positive image.

The single European market: finance

Subjects: subject: European financial integration, dynamic disequilibria
subject: F36

description: For more than twenty-five years after the EEC Treaty was signed, progress in financial integration was discontinuous, uneven, and on the whole modest. This can be attributed to a combination of economic difficulties and policy priorities, but also on reflects on the lack of a coherent, comprehensive approach. The European Commission has now developed a comprehensive project, and has managed to stir the still waters of European cooperation. The author argues, however, that its approach is largely, and indeed intentionally, based on the notion of creating “dynamic disequilibria” that will force action by markets and official authorities.
