description: We study the possibility of producing a new kind of nuclear systems which in addition to ordinary nucleons contain a few antibaryons (antiproton, antilambda, etc.). The properties of such systems are described within the relativistic mean-field model by employing G-parity transformed interactions for antibaryons. Calculations are first done for infinite systems and then for finite nuclei from He to Pb. It is demonstrated that the presence of a real antibaryon leads to a strong rearrangement of a target nucleus resulting in a significant increase of its binding energy and local compression. Noticeable effects remain even after the antibaryon coupling constants are reduced by factor 3-4 compared to G-parity motivated values. We have performed detailed calculations of the antibaryon annihilation rates in the nuclear environment by applying a kinetic approach. It is shown that due to significant reduction of the reaction Q-values, the in-medium annihilation rates should be strongly suppressed leading to relatively long-lived antibaryon-nucleus systems. Multi-nucleon annihilation channels are analyzed too. We have also estimated formation probabilities of bound antibaryon-nucleus systems in antiproton-nucleus reactions and have found that their observation will be feasible at the future GSI antiproton facility. Several observable signatures are proposed. The possibility of producing multi-quark-antiquark clusters is discussed.

description: Nonperturbative treatments of the UV limit of pure gravity suggest that it admits a stable fixed point with positive Newton's constant and cosmological constant. We prove that this result is stable under the addition of a scalar field with a generic potential and nonminimal couplings to the scalar curvature. There is a fixed point where the mass and all nonminimal scalar interactions vanish while the gravitational couplings have values which are almost identical to the pure gravity case. We discuss the linearized flow around this fixed point and find that the critical surface is four-dimensional. In the presence of other, arbitrary, massless minimally coupled matter fields, the existence of the fixed point, the sign of the cosmological constant and the dimension of the critical surface depend on the type and number of fields. In particular, for some matter content, there exist polynomial asymptotically free scalar potentials, thus providing a solution to the well-known problem of triviality.

description: It is generally believed that agricultural interventionism under the European Union’s Common Agricultural Policy represents the payment of political rents to farmers. The authors attempt to show that the concept of political rent known as the rent-seeking theory is not valid for agricultural policy. It is not justified to identify the whole of the subsidies paid to agriculture in the EU as a “political rent”, since political rents cannot be taken to include payments for the supply of public goods or those transfers which compensate for market imperfections. A methodology is proposed for valuing these items, filling a gap existing in the literature on political economy. The authors perform comparative analyses with the aim of calculating the “pure political rent”, based on input-output matrices for representative farms according to the EUFADN typology and on a decomposition of the Hicks-Moorsteen TFP index for the period 2007–2012 and all EU-27 countries. The research hypothesis is proposed that the size of the subsidies retained in agriculture is a function of the political cycle, but also of market imperfections.

description: The main aim of this article is to identify the dynamics of the processes of reproduction of assets (fixed assets excluding land) and the importance of determinants influencing this processes in agricultural holdings in Poland engaged in agricultural accountancy of the FADN. Recognized in the study is the domination of the processes of narrow reproduction of fixed assets in the examined group of farms. In terms of economic recovery, there has been an improvement in the range of the reproduction of assets during the downturn of the dominance of narrow reproduction. The impact of resource factors on the processes of reproduction are more clear in the case of exclusion from surveys farms in which the processes of reproduction do not indicate opportunities for their further development (reproduction indicator below 0.5). It may mean that in the other units, use of resources better served the agricultural purposes of and they were effectively used.

description: Systematic studies of the two high-temperature monolayer oxygen structures that exist on the (110) tungsten surface were performed using low-energy electron microscopy and diffraction measurements. Our work questions the commonly accepted interpretation from the literature that striped oxygen superstructures arise from alternating site-exchanged (S-E) domains. We postulate that the superstructures originate from a misfit between tungsten and oxygen lattices while the striped appearance corresponds to a moiré pattern. Moreover, we show that the two structures, indicated as 113- and 337-phases due to the characteristic directions of the respective moiré patterns, differ considerably in their symmetry properties. This suggests that oxygen atoms in the two overlayers occupy different adsorption sites on average. In particular, the 113-phase features rotational domains that retain mirror symmetries with respect to the [001] and [1-10] directions, whereas the 337-phase is characterized by the appearance of additional domains due to the breaking of these symmetries. We propose structural models for both phases that consistently explain their unusual properties and suggest a universal mechanism for the thermal evolution of oxygen monolayer adsorbed on W(110).

description: The Lévy hypothesis states that inverse square Lévy walks are optimal search strategies because they maximise the encounter rate with sparse, randomly distributed, replenishable targets. It has served as a theoretical basis to interpret a wealth of experimental data at various scales, from molecular motors to animals looking for resources, putting forward the conclusion that many living organisms perform Lévy walks to explore space because of their optimal efficiency. Here we provide analytically the dependence on target density of the encounter rate of Lévy walks for any space dimension $d$ ; in particular, this scaling is shown to be {\it independent} of the Lévy exponent $α$ for the biologically relevant case $d\ge 2$, which proves that the founding result of the Lévy hypothesis is incorrect. As a consequence, we show that optimizing the encounter rate with respect to $α$ is {\it irrelevant} : it does not change the scaling with density and can lead virtually to {\it any} optimal value of $α$ depending on system dependent modeling choices. The conclusion that observed inverse square Lévy patterns are the result of a common selection process based purely on the kinetics of the search behaviour is therefore unfounded.

title: Strategic Change in Further Education
Creators: name: Hannagan, Timothy James
Publisher: name: The Open University
Year: 2004

description: The research focus was to examine how organisations seek to respond to changes in their external environment through the development of strategies which matched organisational capability with external restraints. In April 1993 colleges of further education in England became incorporated bodies, responsible for their own management and their own strategic development under a new national funding framework. This provided an opportunity to research strategic change in these organisations, to investigate the effects on them of the changes in their environment, and to examine the strategies they had developed to enable them to cope with these changes. These strategies were compared with models of strategic change so that consideration could be given to the strategies colleges needed in order to be successful and to cope with future change. This research project covered the period from 1993 until 1999. Colleges were asked, in a national survey, what they considered to be the most important changes they faced at incorporation and in the years immediately after it and how they had coped with these changes. Key issues were identified from the results of this survey, which were followed up in case studies in order to consider the approaches to strategic change in a number of colleges. A conceptual model was developed in order to provide the theoretical foundation for the research and to provide a framework for the conclusions reached as a result. The findings of the research emphasised the importance of environmental assessment and organisational leadership in achieving effective strategic change.

description: In this paper, we investigate the inclusive diffractive hadroproduction for $\rm η_{c}$ and $\rm η_{b}$ at the LHC energies. Based on the NRQCD factorization formalism and the resolved-Pomeron model for the quarkonium production mechanism, we estimate the rapidity, momentum fraction loss dependence of the cross section. We give prediction ratios for single and central diffractive processes with respect to non diffractive process. These inclusive processes are sensitive to gluon content of Pomeron for small-$x$ and Reggeon for large-$x$, useful to study small and large-$x$ physics and good to test different mechanism for $\rm η_{c}$ and $\rm η_{b}$ production at the LHC. They also serve as the background to related exclusive processes thus should be predicted. Our results demonstrate that the Reggeon contribution of diffractive processes can be sizable, even sometimes dominant over Pomeron, and that its study can be useful to better constrain the Reggeon parton content. The experimental study of Reggeon can be carried out in certain kinematic windows.

description: We compute the NLO QCD corrections to the loop-induced gluon fusion contribution in $W^+W^-$ production at the LHC. We consider the full leptonic process $pp\to \ell^+\ell^{\prime\, -}ν_{\ell}{\barν}_{\ell^\prime}+X$, by including resonant and non-resonant diagrams, spin correlations and off-shell effects. Quark-gluon partonic channels are included for the first time in the calculation, and our results are combined with NNLO predictions to the quark annihilation channel at the fully differential level. The computed corrections, which are formally of ${\cal O}(α_{\mathrm{S}}^3)$, increase the NNLO cross section by only about 2%, but have an impact on the shapes of kinematical distributions, in part due to the jet veto, which is usually applied to reduce the top-quark background. Our results, supplemented with NLO EW effects, provide the most advanced fixed-order predictions available to date for this process, and are compared with differential ATLAS data at $\sqrt{s}=$ 13 TeV.

This method leads to the results exact in space-time dimension $D$ having the form of the convergent power series. As an application of this method, we calculate the two--loop master integral for "crossed--triangle" topology which was previously known only up to $O(\ep)$ order. The case when a topology contains several master integrals is also considered. We present an algorithm of the term-by-term calculation of the asymptotical expansion in this case and analyze in detail the "crossed--box" topology with three master integrals.

Annotation-Based Static Analysis for Personal Data Protection

description: This paper elaborates the use of static source code analysis in the context of data protection. The topic is important for software engineering in order for software developers to improve the protection of personal data during software development. To this end, the paper proposes a design of annotating classes and functions that process personal data. The design serves two primary purposes: on one hand, it provides means for software developers to document their intent; on the other hand, it furnishes tools for automatic detection of potential violations. This dual rationale facilitates compliance with the General Data Protection Regulation (GDPR) and other emerging data protection and privacy regulations. In addition to a brief review of the state-of-the-art of static analysis in the data protection context and the design of the proposed analysis method, a concrete tool is presented to demonstrate a practical implementation for the Java programming language.

description: Decisions made by farmers have a strong impact on the environment. One of the goals of agri-environment schemes (AESs) is to influence farmers into making positive contributions to the environment. They are generally voluntary and encourage farmers to participate by paying them for the provision of environmental services. It is important to understand the drivers of farmer behaviour and the choices they make with regards to AESs as this will aid policy makers in creating schemes that have a wider scope and achieve goals. Using Ireland as a case-study, this paper examines farmers’ attitudes to farming, the environment and AESs. A number of attitudinal statements put to 1000 Irish farmers are condensed to seven different attitude groups using factor analysis. These attitudinal variables, along with numerous farm and farmer characteristics, are used in a logistic regression analysis to examine their role in determining participation in AESs. This shows that attitudes especially those pertaining to the benefits and drawbacks of AESs are significant to the participation decision; however there is added complexity from attitudes to farming and the environment. Given the diversity of drivers of farmer behaviour, the design of policies is primordial and must not only be focused on pecuniary aspects but also take into account the wide diversity of farmers in terms of both characteristics and attitudes.

Using the stress function method, we found exact analytical solutions for all characteristic fields of a straight twist disclination in an infinitely extended linear isotropic medium. The elastic stress, elastic strain and displacement have no singularities at the disclination line. We found modified stress functions for the twist disclination. In addition, we calculate the disclination density, effective Frank vector, disclination torsion and effective Burgers vector of a straight twist disclination. By means of gauge theory of defects we decompose the elastic distortion into the translational and rotational gauge fields of the straight twist disclination.

As a concrete example, we compare the proton-proton scattering phase shifts calculated from these potentials. The numerical results document that high precision calculations of the renormalization are performed by the new screening function.

description: Identifying and assessing technology gaps and technology leaps observed in the agricultural productivity change analysis is of paramount importance since it enables the identification of a set of effects that influence the way that inputs are transformed into outputs and resources are allocated between diversified farm activities. Previous studies have ignored the importance of heterogeneity between different farming systems and their characteristics and have also failed to account for the different rates of technology absorption with respect to an unrestricted universal production frontier considering simultaneous generation of main products and by-products. Furthermore, the technology leaps defined as varying rates of technology absorption over time with respect to the unrestricted universal production frontier may lead to miss-specified local production functions and biased efficiency and productivity change estimates. The analysis focused on the regional variation of the production environment, farm specialisation and level of engagement as constraints to productivity gains. By considering two different levels of endogenous and exogenous heterogeneity in the production environment, the analysis used data from the Farm Business Survey of English arable farms for the years 2005-2013 and employed the parametric stochastic meta-frontier analysis to measure sustainable productivity change as producers engage into agricultural and diversified activities as alternative sources of income. The model approaches simultaneous value-adding generation processes to reveal the relationship between change in producers’ endowments and productivity gains in a network application under uncertainty.

description: We revisit inflation with non-canonical scalar fields by applying deformed-steepness exponential potentials. We show that the resulting scenario can lead to inflationary observables, and in particular to scalar spectral index and tensor-to-scalar ratio, in remarkable agreement with observations. Additionally, a significant advantage of the scenario is that the required parameter values, such as the non-canonicality exponent and scale, as well as the potential exponent and scale, do not need to acquire unnatural values and hence can accept a theoretical justification. Hence, we obtain a significant improvement with respect to alternative schemes, and we present distinct correlations between the model parameters that better fit the data, which can be tested in future probes. This combination of observational efficiency and theoretical justification makes the scenario at hand a good candidate for the description of inflation.

description: Occupation of arboreal habitats poses myriad locomotor challenges, driving both anatomical and behavioural innovations across various tetrapod lineages. Here, we report and biomechanically assess a novel, beak-driven locomotor mode – ‘beakiation’ – by which parrots advance along the underside of narrow arboreal substrates. Using high speed videography and kinetic analyses, we describe the limb loading patterns and pendular mechanics of beakiation, and compare the biomechanical characteristics of this gait to other suspensory behaviours (namely, forelimb-driven brachiation and inverted quadrupedal walking). We report that the parrot beak experiences comparable force magnitudes (approx. 150% body weight in the normal plane; approx. 50% body weight in the fore-aft plane) to the forelimbs of brachiating primates. Parrot beakiation is also characterized by longer-than-expected pendular periods, similar to observations of gibbon brachiation. However, in terms of mechanical energy recovery, parrot beakiation is characterized by lower rates of energetic recovery than brachiating specialists: a product of its slower, more careful nature. The observation of this novel behaviour – which adds to a growing base of literature regarding beak-assisted locomotor strategies in birds – highlights the extraordinary behavioural plasticity of birds, the functional versatility of the avian beak, and the difficulties in reconstructing an animal's locomotor repertoire from morphological characteristics alone.
title: Constructions of Identity in Contemporary African Drama: A Comparative Study of Wole Soyinka and Zakes Mda
Creators: name: Agboluaje, Oladipo
Publisher: name: The Open University
Year: 2003

description: This thesis examines identity constructions in contemporary African drama, through a comparative study of Wole Soyinka of Nigeria and Zakes Mda of South Africa. Soyinka and Mda construct African identities from an Afrocentric, universal humanism. Both dramatists locate African identities in the interaction between the individual and the community, which allows for a heterogeneity of African identities. Their different ideas about how African identities are formed arise from the specific social, historical conditions of their respective African contexts. Soyinka's identity constructions are essentialist, deriving from ethnic myth and history. Soyinka's essential African identity varies through social experience. Mda grounds his constructions of African identity in the material experience of apartheid. Mda privileges class over ethnic myth and history. My comparison of the two dramatists and their work reveals how colonialism is implicated in ethnic as well as materialist accounts of African identity. The works of Soyinka and Mda illustrate how African identities vary according to a complexity of social and historical conditions. My conclusion is that notions of African identity are rendered from the personal perspective of the dramatist, perspectives derived from local experience, which is influenced by colonialism.

description: Adoption and extensive use of agricultural innovations is seen as a key avenue for poverty reduction and improved food and nutritional security in developing countries. This paper evaluated the impact of IPM strategy for mango fruit flies suppression on food security with the help of a two-wave panel household survey data collected in Machakos County in Kenya. Using a randomly selected sample of 600, a difference in difference was fitted to the data in order to assess the impact of IPM on food security. The results showed that on average, both IPM participants and non-participants were food secure as measured by per capita calorie intake and Household Dietary Diversity Index (HDDI). The difference in difference estimates indicated that fruit fly IPM had a positive impact on per capita calorie intake but no significant effect on HDDI. Other factors that had an effect on per capita calorie include level of farm income, access to extension services, wealth category and distance to agricultural input market and household size. Our study recommends wider dissemination and upscaling of the fruit fly IPM strategy to facilitate broader impacts on household-level food security.

description: During the period when the Sun was intensely active on October-November 2003, two remarkable solar neutron events were observed by the ground-based neutron monitors. On October 28, 2003, in association with an X17.2 large flare, solar neutrons were detected with high statistical significance (6.4 sigma) by the neutron monitor at Tsumeb, Namibia. On November 4, 2003, in association with an X28 class flare, relativistic solar neutrons were observed by the neutron monitors at Haleakala in Hawaii and Mexico City, and by the solar neutron telescope at Mauna Kea in Hawaii simultaneously. Clear excesses were observed at the same time by these detectors, with the significance calculated as 7.5 sigma for Haleakala, and 5.2 sigma for Mexico City. The detector onboard the INTEGRAL satellite observed a high flux of hard X-rays and gamma-rays at the same time in these events. By using the time profiles of the gamma-ray lines, we can explain the time profile of the neutron monitor. It appears that neutrons were produced at the same time as the gamma-ray emission.

description: Financially rewarding farmers is an unconventional approach to agricultural extension. We evaluate an extension program, primarily delivered through farmer discussion groups, which rewarded farmers with conditional payments. Combining a matching model with a difference-in-difference estimator to data from the Irish National Farm Survey, we found that there was no significant impact on farm performance from the extension program over a four year period. The results align with previous research and would suggest that financial incentives in the form of conditional payments are not an ideal strategy for agricultural extension or technology adoption.
A quantum heat exchanger for nanotechnology

description: In this paper, we design a quantum heat exchanger which converts heat into light on relatively short quantum optical time scales. Our scheme takes advantage of heat transfer as well as collective cavity-mediated laser cooling of an atomic gas inside a cavitating bubble. Laser cooling routinely transfers individually trapped ions to nano-Kelvin temperatures for applications in quantum technology. The quantum heat exchanger which we propose here might be able to provide cooling rates of the order of Kelvin temperatures per millisecond and is expected to find applications in micro and nanotechnology.

description: The main research questions of present study are to examine the most important reasons and explanations for failure or success of new, emerging co-operatives and to analyse the main macro- and micro-economic conditions for successful collective action (e.g. marketing) done by producer-owned organisations (formal co-operation, e.g. co-operatives, producer organisations etc.) or by collaboration of agricultural producers without a legal form or written agreement (informal co-operation) in a NMS like Hungary. We use literature review and secondary data collection as well, but our main focus is on empirical level. In collaboration with Hungarian Chamber of Agriculture we gained information from 7,728 of its agricultural producer members on their co-operation activity through an on-line based empirical survey in summer 2015. According to the findings of the above national survey more than 51% of the respondents do not cooperate at all in any forms of cooperation. The biggest obstacle to co-operation is in the attitude of the farmers: they do not like to depend on anybody else and/or they do not like to commit themselves. Huge lack of information is also a big barrier. We conclude with listing the micro- and macro-level factors economic conditions for successful collective action.

description: Colloid or nanoparticle mobility under confinement is of central importance to a wide range of physical and biological processes. Here, we introduce a minimal model of particles in a hydrodynamic continuum to examine how particle shape and concentration affect the transport of particles in spherical confinement. Specifically, an immersed boundary-General geometry Ewald-like approach is adopted to simulate the dynamics of spheres and cylinders under the influence of short-and long-range fluctuating hydrodynamic interactions with appropriate non-slip conditions at the confining walls. An efficient $\it{O(N)}$ parallel finite element algorithm is used, thereby allowing simulations at high concentrations, while a Chebyshev polynomial approximation is implemented in order to satisfy the fluctuation-dissipation theorem. A concentration-dependent anomalous diffusion is observed for suspended particles. It is found that introducing cylinders in a background of spheres, i.e. particles with a simple degree of anisotropy, has a pronounced influence on the structure and dynamics of the particles. First, increasing the fraction of cylinders induces a particle segregation effect, where spheres are pushed towards the wall and cylinders remain near the center of the cavity. This segregation leads to lower mobility for the spheres relative to that encountered in a system of pure spheres at the same volume fraction. Second, the diffusive-to-anomalous transition and the degree of anomaly--quantified by the power-law exponent in the mean square displacement vs. time relation-both increase as the fraction of cylinders becomes larger. These findings are of relevance for studies of diffusion in the cytoplasm, where proteins exhibit a distribution of size and shapes that could lead to some of the effects identified in the simulations reported here.

description: One of the most important features in the international trade over the recent decades has been the increased fragmentation of the production process. This has been facilitated, in part, by the development and maturation of global value chains (GVCs).The improved availability of value-added trade data allows us to identify more clearly what fragment in the production chain is internationally competitive in a particular country. The paper examines global agri-food export performance in the light of these changes with special emphasis on the impacts of economic crisis using the concept of normalised revealed comparative advantage (NRCA) in terms of both gross exports and value-added for 61 countries over period 1995 and 2011. Systematically comparing these distributions reveals significant differences for NRCA based on gross exports versus value-added data.
