description: The cosmological collider provides a model-independent probe of particle physics during inflation. We extend the study of cosmological collider physics to much smaller scales through gravitational wave (GW) probes. With a Chern-Simons interaction, a massive vector field can obtain a chemical potential and its particle production can cause significant non-Gaussian GW signals. We calculate the mass and spin dependences of the induced GW 3-point correlation function in the squeezed limit, and estimate its amplitude. Such signals may be detectable in the current and upcoming GW interferometer experiments.

description: Peer support groups can offer parents of children with disability, positive well-being outcomes. Peer support groups not only provide opportunities for connections with others with similar experiences but also provide resources and information, emotional support, a sense of belonging and may help reduce stress and isolation. Peer support groups are an established form of support existing within family centred practice. However, it is unclear whether peer support groups achieve the outcomes that they aim to deliver. Further, little is known about the longer-term outcomes for parents attending such groups. This study aimed to explore the medium- and long-term outcomes and experiences of parents who participated in a peer support programme (the Now and Next programme) for parents of children with disability. Well-being data were collected at three timepoints (Ts): prior to commencing the programme (T1), immediately after completion of the programme (T2) and 6–30 months after completion of the programme (T3). Results of the study showed empowerment and well-being improved from T1 to T2, with gains maintained at T3. Hope scores did not significantly change over time. Participants continued to set and achieve goals over time using resources from the programme. Improvements in parents' well-being and empowerment scores were maintained in the longer-term. Our study contributes to evidence confirming sustained long-term outcomes of peer support programmes and demonstrates that building parent capacity, empowerment and well-being has a lasting effect on the parents of children with disability.

description: Early studies of . the productivity of pesticide expenditures determined a very high marginal product. The marginal product of control will depend upon the level of the particular pesticide, the host crop, initial pest infestation, other state variables, and the functional form. The excessively high marginal product of generic pesticide expenditures estimated in some earlier studies are not evident in our analysis of crop and herbicide specific experimental data. Field-level data for winter wheat in south eastern Washington indicate increasing returns to herbicide application are unlikely to occur in typical field application.

description: To better understand policy integration, it is necessary to improve the kno\/Jledge of the policy effects, in particular their environmental impacts, and continue to develop analytical instruments to assess them. In this paper, several integration instruments such as regulatory approach, economic incentive approach, cross-compliance approach and advisory approach are being examined. Consistency between farm income support and environmental objectives has been enhanced through compliance mechanisms. In practice, agricultural and environmental policy approach is more likely to adopt a cross-compliance approach, making income support payments contingent upon the recipients' compliance with pre-determined environmental standards.

description: The term sustainability is conceptualized as a having double meaning--inter-generational and intra-generational equity. Sustainable agriculture (SA) is also understood as a totality encompassing agricultural and rural development. Korean sustainable agriculture evolved since the late 1970s as a "movement'' to restore the soil, undergoing rapid expansion in the 1990s. A few studies on Korean sustainable agriculture have indicated that the farmers in this field are younger and more educated, implying that the sustainable agriculture is a promising alternative farming technique. Consumers are also younger, better educated, wealthier, and very often from the countryside. A hypothesis is provided here about the existence of two types of SA farmers, the "movement type" and "business type" practitioners. The possible convergence between sustainable agriculture and sustainable rural development, and its necessity, is discussed and proposed.

We will clarify the relation between heavy quark free energies and potentials used to analyze the melting of heavy quark bound states. Furthermore, we present calculations of meson spectral functions which indicate that the charmonium ground states, J/psi and eta_c, persist in the quark gluon plasma as well defined resonances with no significant change of their zero temperature masses at least up to T ~ 1.5 T_c. We also briefly comment on the current status of lattice calculations at non-vanishing baryon number density.

description: The subject of this thesis is the examination of the intersection between the patent protection for pharmaceuticals and the effective implementation of the human right to health and particularly access to essential and affordable medicines. Access to medicines poses crucial questions as regards to its protection as a human right and at the same time as an economic value in international trade regime in terms of the patent protection for pharmaceuticals. The study is divided in two parts. Part I sets out the international framework for the protection of the right to health and access to medicines. Subsequently, part II examines the protection of intellectual property rights of pharmaceutical industry on the basis of the TRIPS agreement as well as the restrictions placed on affordable access to medicines.

description: We study the Brownian motion of a charged test particle coupled to electromagnetic vacuum fluctuations near a perfectly reflecting plane boundary. The presence of the boundary modifies the quantum fluctuations of the electric field, which in turn modifies the motion of the test particle. We calculate the resulting mean squared fluctuations in the velocity and position of the test particle. In the case of directions transverse to the boundary, the results are negative. This can be interpreted as reducing the quantum uncertainty which would otherwise be present.

description: Neutron measurements on Ca{1-x}La{x}MnO3 (0.00 <= x <= 0.20) reveal the development of a liquid-like spatial distribution of magnetic droplets of average size ~10 Angstroms, the concentration of which is proportional to x (one cluster per ~60 doped electrons). In addition, a long-range ordered ferromagnetic component is observed for ~0.05 < x < ~0.14. This component is perpendicularly coupled to the simple G-type antiferromagnetic (G-AFM) structure of the undoped compound, which is a signature of a G-AFM + FM spin-canted state. The possible relationship between cluster formation and the stabilization of a long-range spin-canting for intermediate doping is discussed.

description: This paper assesses farmers' incentives and conditioning factors that hinder or promote adaptation strategies and evaluates its impact on crop productivity by utilizing household level data collected in 2011 from nationally representative sample households in Malawi. We distinguish between (i) exposure to climatic disruptions, (ii) bio-physical sensitivity to such disruptions, (iii) household adaptive capacity in terms of farmers' ability to prepare and adjust to the resulting stress, and, finally, (iv) system-level adaptive capacity that serve as enabling factors for household-level adaptation. We employ a multivariate probit (MVP) and instrumental variable technique to model farming practice selection decisions and their yield impact estimates. We find that exposure to delayed onset of rainfall and greater climate variability as represented by the coefficient of variation of rainfall and temperature is positively associated with the choice of risk-reducing agricultural practices such as tree planting, legume intercropping, and soil and water conservation (SWC); however, it reduces the use of inputs (such as inorganic fertilizer) whose risk reduction benefits are uncertain. Biophysical sensitivity of plots increases the likelihood of choice of tree planting and SWC. In terms of household adaptive capacity, we find that wealthier households are more likely to adopt both modern and sustainable land management (SLM) inputs; and are more likely to adopt SLM inputs on plots under more secure tenure. In terms of system-level adaptive capacity, results show the key role of rural institutions, social capital and supply-side constraints in governing selection decisions for all practices considered, but particularly for tree planting and both organic and inorganic fertilizer. Finally for productivity, we find that on average use of both modern and SLM practices have positive and statistically significant impact on productivity of maize. For SLM practices that also respond to exposure and sensitivity, these results provide direct evidence of their potential to aide households in adapting to further climate change. Results presented have implications for understanding and overcoming barriers to selection for each practice, distinguishing structural aspects such as exposure and sensitivity from potential interventions at the household or systemic levels linked to adaptive capacity.

description: We study semiclassical approximations to the time evolution of coherent states for general spin-orbit coupling problems in two different semiclassical scenarios: The limit \hbar to zero is first taken with fixed spin quantum number s and then with \hbar*s held constant. In these two cases different classical spin-orbit dynamics emerge. We prove that a coherent state propagated with a suitable classical dynamics approximates the quantum time evolution up to an error of size \sqrt{\hbar} and identify an Ehrenfest time scale. Subsequently an improvement of the semiclassical error to an arbitray order \hbar^{N/2} is achieved by a suitable deformation of the state that is propagated classically.

description: Food price volatility spells have fuelled the debate about the reliability of world markets as a source of food. At the heart of this debate lies the question of whether food price spikes are generated by the forces of demand and supply, or by speculation. We test for 'bubble' behaviour ' movements in the prices that cannot be explained by market fundamentals ' by applying the generalized version of the supremum Augmented Dickey-Fuller to several food price indices and 28 agricultural commodity prices. Our findings suggest that few food commodities exhibited bubble behaviour during the 2008 food price episode, with the price surges of 2010 and 2011 being due to market fundamentals. These spells of explosive behaviour are, in general, short-lived. Other commodities, which are also traded in futures markets, appear to respond only to the forces of supply and demand. Market conditions, such as stagnant productivity growth and low carry-over stocks, tend to shape the effect of speculation on prices. In some markets, trade policies, such as export bans, also appear to be crucial in generating bubble behaviour in prices.

description: This paper assesses Bangladesh's progress towards eradicating hunger, food insecurity and malnutrition, and how the National Food Policy Capacity Strengthening Programme (NFPCSP) implemented by FAO and the Government of Bangladesh contributed to this progress. To this effect, it uses FAO's Food Security Commitment and Capacity Profile method to assess changes in Bangladesh's food security commitments and capacities and compares the food security situation prior to and eight years into the NFPCSP intervention. It finds that although progress has been made in particular in income poverty, this has not resulted in commensurate nutritional outcomes. Substantial progress in Bangladesh's commitment and capacity to improve food security and nutrition has been made with specific reference to policies, programmes and legal frameworks for FSN, human and financial resources allocated to FSN, stakeholder coordination mechanisms. Decision-making in FSN issues is now increasingly based on evidence generated through a relatively functional information system although the production and dissemination of information to policy-makers needs to be further improved. NFPCSP has clearly contributed to these changes through its innovative approach. The paper concludes with a series of lessons learned from the Bangladesh experience as well as a set of recommendations for improvement of the FSCCP methodology.

description: The agricultural economics literature provides various estimates of the number of farms and small farms in the world. This paper is an effort to provide a more complete and up to date as well as carefully documented estimate of the total number of farms in the world, as well as by region and level of income. It uses data from numerous rounds of the World Census of Agriculture, the only dataset available which allows the user to gain a complete picture of the total number of farms globally and at the country level. The paper provides estimates of the number of family farms, the number of farms by size as well as the distibution of farmland by farm size. These estimates find that: there are at least 570 million farms worldwide, of which more than 500 million can be considered family farms. Most of the world's farms are very small, with more than 475 million farms being less than 2 hectares in size. Although the vast majority of the world's farms are smaller than 2 hectares, they operate only a small share of the world's farmland. Farmland distribution would seem quite unequal at the global level, but it is less so in low- and lower-middle-income countries as well as in some regional groups. These estimates have serious limitations and the collection of more up-to-date agricultural census data, including data on farmland distribution is essential to our having a more representative picture of the number of farms, the number of family farms and farm size as well as farmland distribution worldwide.

description: We examine the nature of relationship between prices of crude oil, ethanol and grains (maize, wheat and rice). Our working hypothesis is that profit maximization, the US biofuel policies and automotive engine technology give rise to a nonlinear relationship between oil and ethanol prices, and by extension between oil and grains prices. While legislation sets a floor in the ethanol market, engine technology, which shapes fuel substitution, sets a ceiling. We explore price relationships in the food-ethanol-oil nexus by applying both discrete and smooth threshold error correction models. First, we find that oil prices are the long run drivers of ethanol and grains prices. Second, ethanol prices co-move with oil prices in the long run. However, in the short run, oil and ethanol prices are linked in a nonlinear manner. Ethanol prices appear to drift apart from the path as this is determined by oil prices, due to policy changes. Adjustment back to the long run equilibrium the path is rapid, less than two months, when the deviations are small. Large deviations take more time to be corrected.

description: This study investigates the effects of narcissism on entrepreneurial intentions through entrepreneurial alertness, entrepreneurial passion, and internal locus of control. The data for our research model is collected from a sample of 422 business students from nine universities in Vietnam. The findings from structural equation modelling reveal that the relationship between narcissism and entrepreneurial intentions was fully mediated by both entrepreneurial alertness and entrepreneurial passion. Moreover, internal locus of control is found to moderate the relationships between entrepreneurial alertness and entrepreneurial passion and entrepreneurial intentions. Our study provides important theoretical and practical implications.

description: Agriculture in Sub-Saharan Africa must undergo significant productivity improvements to meet the combined challenges of population growth and climate change. A proposed means of achieving such improvements is increased use of a 'climate-smart agriculture' approach to agricultural development policy-making, which emphasizes the use of farming techniques that (1) increase yields, (2) reduce vulnerability to climate change, and (3) reduce greenhouse gas emissions. Two countries that are prioritizing such an approach within the framework of a Climate-Smart Agriculture project are Malawi and Zambia . These countries are promoting the use of agroforestry and conservation agriculture with the aim of improving the productivity of their smallholder agricultural systems under climate change . This review synthesizes evidence on the use, yie ld and socio - economic impacts of these farming techniques. Key findings are that agroforestry is a promising option for smallholder farmers with well - documented yield and profitability improvements. Evidence supporting the use of conservation agriculture i n the target countries is also positive but weaker . Adoption rates, although higher than those in other African countries, are lower than would be expected given the potential benefits , and resources spent on promotion . Key constraints and needs for furthe r research are documented

description: We develop a statistical description of chaotic wavefunctions in closed systems obeying arbitrary boundary conditions by combining a semiclassical expression for the spatial two-point correlation function with a treatment of eigenfunctions as Gaussian random fields. Thereby we generalize Berry's isotropic random wave model by incorporating confinement effects through classical paths reflected at the boundaries. Our approach allows to explicitly calculate highly non-trivial statistics, such as intensity distributions, in terms of usually few short orbits, depending on the energy window considered. We compare with numerical quantum results for the Africa billiard and derive non-isotropic random wave models for other prominent confinement geometries.

description: Purpose: This paper aims to examine the impacts of financial and nonfinancial incentives on the development of employee work motivation and knowledge sharing in the postpandemic environment. The paper further investigates the role of transformational leadership as a moderator in enhancing the relationship between work motivation and knowledge sharing. Design/methodology/approach: Adopting a quantitative approach, the study uses data collected from multiple informants, specifically senior managers, in Nepalese manufacturing and service business-to-business (B2B) firms. Findings: Contrary to prior research, the results reveal that nonfinancial incentives have a stronger impact on work motivation in the postpandemic era. This enhanced work motivation, in turn, contributes to knowledge sharing, with transformational leadership further strengthening the relationship. Practical implications The findings suggest that B2B firms should consider moving toward leveraging nonfinancial incentives to motivate employees to develop knowledge sharing initiatives, especially in challenging circumstances such as those experienced in the postpandemic era. In addition, it is recommended that chief executive officers adopt a transformational leadership style to facilitate effective knowledge sharing within their firms. Originality/value In a developing economy and amid the challenges of the global pandemic, there has been limited research exploring the possible effects that financial and nonfinancial incentives could have on work motivation and knowledge sharing. This research bridges this gap by providing a fresh perspective on work motivation and knowledge management in B2B firms, contributing novel insights to the literature.

description: Micronutrients are defined as substances in foods that are essential for human health and are required in small amounts. They include all of the known vitamins and essential trace minerals. Micronutrient malnutrition affects a third to a half of the global population. It causes untold human suffering and levies huge costs on society in terms of unrealized human potential and lost economic productivity. The goal of this paper is to identify deficiencies in the food system that lead to micronutrient malnutrition and explore and evaluate strategies for its prevention. We examine the impact of agricultural practices on micronutrients in the food supply, including cropping systems, soil fertility and animal agriculture. We then discuss the potential of biofortification 'i.e. increasing the concentration of micronutrients in staple food crops through conventional plant breeding or genetic engineering' as a means to reduce micronutrient deficiency. In addition, we discuss the impact of food losses and food waste on micronutrients in the food supply, and we explore successful strategies to preserve micronutrients from farm to plate, including food fortification. Our review of the literature sheds light on the advantages and limitations of alternative interventions to reduce micronutrient deficiencies along the supply chain. We end with recommendations for actions that will reduce the prevalence of micronutrient malnutrition.

description: We examine how the transformation of food value chains (FVCs) influence the triple malnutrition burden (undernourishment, micronutrient deficiencies and over-nutrition) in developing countries. We propose a FVC typology (modern, traditional, modern-to-traditional, and traditional-to-modern) that takes into account the participants, the target market, and the products offered. Next, we propose selected hypotheses on the relationship between each FVC category and elements of the triple malnutrition burden. The primary finding is that the transformation of FVCs creates challenges and opportunities for nutrition in developing countries. For example, Modern FVCs may increase over-nutrition problems and alleviate micronutrient deficiencies for urban people with relatively high incomes. However, they have little nutritional impacts among rural residents and urban poor people, who primarily depend on traditional FVCs to access adequate quantities of calories and micronutrients. In addition, modern food manufacturers are leveraging traditional distribution networks (modern-to-traditional FVCs), substantially increasing access to low-priced processed/packaged foods in rural areas and low-income urban neighbors with mixed impacts on the triple burden of malnutrition. Further research should focus on the influence of FVC transformation on reduction of micronutrient deficiencies, on modeling demand substitution effects across food categories and the attendant policy implications for malnutrition.

description: The standard model of cosmology is based on the hot Big Bang theory and the inflationary paradigm. Recent precise observations of the temperature and polarization anisotropies in the cosmic microwave background and the matter distribution in large scale structures like galaxies and clusters confirm the general paradigm and put severe constrains on variations of this simple idea. In this essay I will discuss the epistemological foundations of such a paradigm and speculate on its possible realisation within a more fundamental theory.

description: A vacancy defect is described by a Frenkel--Kontorova model with a discommensuration. This vacancy can migrate when interacts with a moving breather. We establish that the width of the interaction potential must be larger than a threshold value in order that the vacancy can move forward. This value is related to the existence of a breather centred at the particles adjacent to the vacancy.

description: Background and Objective The novel Coronavirus also called COVID-19 originated in Wuhan, China in December 2019 and has now spread across the world. It has so far infected around 1.8 million people and claimed approximately 114,698 lives overall. As the number of cases are rapidly increasing, most of the countries are facing shortage of testing kits and resources. The limited quantity of testing kits and increasing number of daily cases encouraged us to come up with a Deep Learning model that can aid radiologists and clinicians in detecting COVID-19 cases using chest X-rays. Methods In this study, we propose CoroNet, a Deep Convolutional Neural Network model to automatically detect COVID-19 infection from chest X-ray images. The proposed model is based on Xception architecture pre-trained on ImageNet dataset and trained end-to-end on a dataset prepared by collecting COVID-19 and other chest pneumonia X-ray images from two different publically available databases. Results and Conclusion CoroNet has been trained and tested on the prepared dataset and the experimental results show that our proposed model achieved an overall accuracy of 89.6%, and more importantly the precision and recall rate for COVID-19 cases are 93% and 98.2% for 4-class cases (COVID vs Pneumonia bacterial vs pneumonia viral vs normal). For 3-class classification (COVID vs Pneumonia vs normal), the proposed model produced a classification accuracy of 95%. The preliminary results of this study look promising which can be further improved as more training data becomes available. Overall, the proposed model substantially advances the current radiology based methodology and during COVID-19 pandemic, it can be very helpful tool for clinical practitioners and radiologists to aid them in diagnosis, quantification and follow-up of COVID-19 cases.

description: With the prevalence of the Internet, the number of its users is continuously increasing. Therefore, digital advertising is becoming an essential tool for the consumers to be informed of products and services (Cheung, 2006). From the day social media were invented they are endlessly gaining popularity among users and companies started incorporating them in their marketing strategy (Chi, 2011). The scope of this study is to examine the role of the Internet in affecting consumers’ behavior and the ways in which companies are integrating digital advertising in their strategy, in order to create brand awareness and achieve customer loyalty. Also, nowadays with the immoderate use of social media, companies find it more convenient to target their audience and build a strong relationship with it. Therefore, this dissertation will be particularly concentrated on strategies concerning product placement in social media, investigating their influence on the purchase intentions of individuals. Moreover, another area of examination will be gamification, which refers to the use of game elements in different sectors. Gamification is considered a contemporary advertising tool that is distinguished among other ways of reaching the audience. The focus will be on whether gamification psychology is enhancing customer loyalty to a brand.
description: Με την επικράτηση του Διαδικτύου, ο αριθμός των χρηστών του αυξάνεται συνεχώς. Επομένως, η ψηφιακή διαφήμιση καθίσταται απαραίτητο εργαλείο για την ενημέρωση των καταναλωτών για προϊόντα και υπηρεσίες (Cheung, 2006) Από την ημέρα που τα κοινωνικά μέσα εφευρέθηκαν αποκτούν δημοτικότητα μεταξύ των χρηστών και οι εταιρείες άρχισαν να τα ενσωματώνουν στη στρατηγική μάρκετινγκ τους (Chi, 2011). Σκοπός αυτής της μελέτης είναι να εξεταστεί ο ρόλος του Διαδικτύου στην επίδραση της συμπεριφοράς των καταναλωτών και των τρόπων με τους οποίους οι εταιρείες ενσωματώνουν την ψηφιακή διαφήμιση στη στρατηγική τους, προκειμένου να δημιουργήσουν την αναγνωρισιμότητα του προϊόντος τους και να επιτύχουν την αφοσίωση των πελατών. Επίσης, στις μέρες μας με τη χρήση των μέσων κοινωνικής δικτύωσης, οι εταιρείες το βρίσκουν πιο βολικό να στοχεύουν το κοινό τους και να δημιουργούν μια ισχυρή σχέση με αυτό. Επομένως, αυτή η μελέτη θα επικεντρωθεί ιδιαίτερα σε στρατηγικές που αφορούν την τοποθέτηση προϊόντων στα μέσα κοινωνικής δικτύωσης, διερευνώντας την επίδρασή τους στις προθέσεις αγοράς του κοινού. Επιπλέον, ένας άλλος τομέας εξέτασης θα είναι η παιχνιδοποίηση, η οποία αναφέρεται στη χρήση στοιχείων παιχνιδιού σε διαφορετικούς τομείς. Η παιχνίδοποίηση θεωρείται ένα σύγχρονο διαφημιστικό εργαλείο που διακρίνεται μεταξύ άλλων τρόπων προσέγγισης του κοινού. Θα δοθεί έμφαση στο κατά πόσο η ψυχολογία της παιχνιδοποίησης ενισχύει την αφοσίωση των πελατών σε μια μάρκα.
