description: Knowledge about the size and distribution of returns from alternative broad types of R&D and promotion investments permit strategic-level decisions about resource allocation, both within and across research programs. The Australian sheep meat and wool industries are characterised by strong cross-commodity relationships due to the joint product nature of the industries. An equilibrium displacement model of the Australian sheep meat and wool industries was developed to account for these relationships and any indirect benefits and costs arising from spill-over and feedback effects between the industries as a result of research-induced innovation or promotion. The potential annual returns and their distribution among the various industry sectors were estimated from different hypothetical investment scenarios to demonstrate the model's relevance to R&D and promotion policy and decision-making.

description: In this paper, we want to emphasize the pivotal role played by strings in the model realizing de Sitter using an expanding bubble, proposed and subsequently developed in arXiv:1807.01570, arXiv:1907.04268, and arXiv:2001.07433. Contrary to the Randall-Sundrum model of brane-localized gravity, we use the end points of radially stretched strings to obtain matter sourcing gravity induced on the bubble wall. This allows us to reinterpret the possible volume divergence coming from naive dimensional reduction as mass renormalization in four dimensional particle physics. Furthermore, we argue that the residual time dependence in the bulk, pointed out by some recent work as a possible shortcoming of such models, is automatically cured in presence of these stringy sources.

description: Neutron inelastic scattering investigations have been performed on the spin tetrahedral system Cu_2Te_2O_5X_2 (X = Cl, Br). We report the observation of magnetic excitations with a dispersive component in both compounds, associated with the 3D incommensurate magnetic order that develops below $T^{Cl}_{N}$=18.2 K and $T^{Br}_{N}$=11.4 K. The excitation in Cu_2Te_2O_5Cl_2 softens as the temperature approaches $T^{Cl}_{N}$, leaving diffuse quasi-elastic scattering above the transition temperature. In the bromide, the excitations are present well above $T^{Br}_{N}$, which might be attributed to the presence of a degree of low dimensional correlations above $T^{Br}_{N}$ in this compound.
Science Meets Reality: Economic Efficiency, Markets, Institutions and Food Security

description: Food still is, and will continue to be, a basic issue at every day decision process in human behaviour. Food consumption has been a problematic issue in human history and today is also recognized as a basic pillar for human health and welfare/quality of life. From a global problem up to the middle of the eighties, right now food security is mainly a local issue (however a macro-level approach continued to be necessary for long run perspective and food safety concerns in trade and commercialization). Food and nutritional concerns today still are unforgetable issues on a local base perspective in many regions: the most common problems are related to the access and consumption to achieve the minimum nutritional requirements, but also other dimensions such as production, transformation, distribution and logistical aspects of the “food equation”, mainly in less developed countries, are crucial aspects to be taken into consideration.
Economic effciency from a production perspective in the food sector, measured in terms of output per unit of input (technical and technological innovation) achieved one of the best performances in terms of development in the last 30 years globally and in most regions in the world (few exceptions, like Sub-Sahara countries and some others). The same can not be refered in regard to markets and institutional innovations. In fact, looking at institutions including markets and governments, it is necessary to explore and identify the several observed failures (institutional and governance failures: markets, governmental and others) were science can make a contribution. This is the main purpose of the current research, which is starting based on observed problems and applied solutions with good results in many situations, but also pointing out many other situations were solutions are needed based on the old instruments, but also based on innovative procedures. The method followed explores the basic theoretical approach in production theory and in consumption micro-economic concepts, allowing the introduction of some new proposals in regard to efficiency measures. Adding to those aspects some new questions and models are discussed in regard to the “institutional/organizational economics” in the actual world, providing support for improvement measures (and policy suggestions).
The Brasilien case is explored in more detail (the “Fome Zero Program”), but also some African examples are used to illustrate that many solutions will have to rely on technological changes, but also on institutional innovations.

description: Consider the Klein-Gordon equation (KGE) in $\R^n$, $n\ge 2$, with constant or variable coefficients. We study the distribution $μ_t$ of the random solution at time $t\in\R$. We assume that the initial probability measure $μ_0$ has zero mean, a translation-invariant covariance, and a finite mean energy density. We also asume that $μ_0$ satisfies a Rosenblatt- or Ibragimov-Linnik-type mixing condition. The main result is the convergence of $μ_t$ to a Gaussian probability measure as $t\to\infty$ which gives a Central Limit Theorem for the KGE. The proof for the case of constant coefficients is based on an analysis of long time asymptotics of the solution in the Fourier representation and Bernstein's `room-corridor' argument. The case of variable coefficients is treated by using an `averaged' version of the scattering theory for infinite energy solutions, based on Vainberg's results on local energy decay.

description: Laos is a mountainous country with poor roads and a high rate of poverty incidence, especially in rural areas. It is obvious that better roads could reduce poverty, but by how much? And what forms of road improvement reduce poverty the most? The economic effects of road improvement are complex and multi-channeled. This paper uses a multi-household general equilibrium modeling approach to study these issues. The results indicate that road improvement does reduce poverty but that the quantitative impact depends heavily on the types of road that are provided and the areas in which the road is located.
A Self-routing Strategy for 3D Mesh-Connected All-optical Packet Switched Multiprocessor Systems

description: Interprocessor communication becomes the bottleneck in massively parallel computing limiting the performance of supercomputing systems. Optical technology is a promising solution with extraordinarily quick response time supporting enormous bandwidth. To adopt it in multiprocessor systems efficient routing techniques are needed. We propose a novel self-routing strategy for all optical packet switched networks. It supports point-to multicast transmissions by 3D hierarchical topology with fault detection resulting in a greater degree of design freedom and a relaxation of design constraints hence achieves remarkable routing performance.
The proposed scheme eliminates the need for table lookup. Despite that memory requirement to lookup tables is no longer of concern, the OEO (Optical-Electrical Optical) conversion undoubtedly degrades the performance since it has to be performed at each intermediate node defeating the goal of using optics in the first place. Optical logic is still in its infancy so involving complex logic in header decoding won't achieve desirable performance. We harness the features inherent in optics to achieve decoding and data directional capability in real time.
We also eliminate the need for optical buffering by aggressively reducing the probability of data contention and unavailability of outgoing links at each intermediate node. We accommodate multicasting without packet replication by encoding in header the routing services to multicast groups. The technique is unique and demonstrates the dynamic nature of our self-routing scheme. Preliminary simulation results have proved our approach superior and feasible, with the needed reliability and the attractive performance it can provide

description: Optical atomic clocks promise timekeeping at the highest precision and accuracy, owing to their high operating frequencies. Rigorous evaluations of these clocks require direct comparisons between them. We have realized a high-performance remote comparison of optical clocks over km-scale urban distances, a key step for development, dissemination, and application of these optical standards. Through this remote comparison and a proper design of lattice-confined neutral atoms for clock operation, we evaluate the uncertainty of a strontium (Sr) optical lattice clock at the 1x10-16 fractional level, surpassing the best current evaluations of cesium (Cs) primary standards. We also report on the observation of density-dependent effects in the spin-polarized fermionic sample and discuss the current limiting effect of blackbody radiation-induced frequency shifts.

description: An undesirable consequence of grazing activities in eastern Australia is the quantity of sediment emptying into the Great Barrier Reef Lagoon. One of the challenges to reducing sediment loads stems from the lack of private incentives to improve land management practices. There is also a poor understanding of the financial implications resulting from the adoption of sustainable management practices, and, in particular the lack of scientific and economic knowledge linking on-farm management actions to catchment scale impacts. Bio-economic modelling has been used to identify the economic and environmental trade-offs encountered when grazing strategies are altered to reduce off-farm sediment movement from a black spear grass pasture in central Queensland.

To the best of our knowledge, this is the first stability result of such type for periodic multi-solitons of large size of an integrable PDE.

Επίσης στοχεύει να αναλύσει τα κίνητρα που καθοδηγούν την επιλογή ξενοδοχείων με βάση το Hotel Concept, καθώς και τις αντιλήψεις των τουριστών για τα θεματικά και lifestyle ξενοδοχεία που ακολουθούν κάποιο ιδιαίτερο concept. Η έρευνα υιοθέτησε μεικτή μέθοδο προκειμένου να προσεγγίσει ολοκληρωμένα το θέμα της εργασίας. Συγκεκριμένα έγινε ποιοτική έρευνα μέσω συνεντεύξεων με Διοικητικά Στελέχη του τουρισμού και ποσοτική έρευνα μέσω ερωτηματολογίων που διανεμήθηκαν σε ένα συγκεκριμένο δείγμα πληθυσμού. Τα ευρήματα αποκάλυψαν ότι το Hotel Concept εκφράζεται κυρίως μέσα από ξενοδοχεία πολυτελείας. Παρότι μόνο ένα μικρό ποσοστό του δείγματος γνώριζε για αυτά τα ξενοδοχεία και είχε επισκεφθεί κάποιο, η πλειοψηφία εξέφρασε θετική τάση προς την επιλογή ανάλογου καταλύματος για μελλοντική διαμονή. Επιπλέον, τα Διοικητικά Στελέχη του τουρισμού υπογράμμισαν ότι το Hotel Concept είναι μία εξελισσόμενη τάση που εμφανίζεται σε ξενοδοχεία ανεξαρτήτως μεγέθους, τόνισαν την σημαντικότητα της εμπειρίας της διαμονής, επικεντρώθηκαν στα βασικά χαρακτηριστικά που αποτελούν το Hotel Concept, ενώ εκτίμησαν ότι η έρευνα είναι αναγκαία προτού υλοποιηθεί ένα νέο Concept. Συνολικά η μελέτη αυτή εμβαθύνει στην έννοια του Hotel Concept και παρουσιάζει τις απόψεις των τουριστών και των Διοικητικών Στελεχών.
description: The purpose of this research is to investigate how the Hotel Concept is designed, to define its characteristics and its relevance to Brand Experience. It also aims to analyze the motivations that guide the selection of hotels based on the Hotel Concept, as well as tourists' perceptions of themed and lifestyle hotels that follow a particular concept. The research adopted a mixed method approach in order to comprehensively approach the topic of the study. Specifically, qualitative research was conducted through interviews with Tourism Managers and quantitative research through questionnaires distributed to a specific sample of the population. The findings revealed that the Hotel Concept is mainly expressed through luxury hotels. Although only a small percentage of the sample knew about these hotels and had visited one, the majority expressed a positive tendency to choose a similar accommodation for future stays. In addition, the Tourism Executives highlighted that Hotel Concept is an evolving trend that occurs in hotels regardless of size, stressed the importance of brand experience, focused on the key characteristics that make up the Hotel Concept, and suggested that research is necessary before a new Concept can be implemented. Overall, this study delves into the Hotel Concept meaning and presents the views of tourists and the Tourism Managers.

The cross sections are small, generally at the attobarn level, with a few notable exceptions which might provide additional supersymmetric parameter measurements. We discuss in detail how to consistently define supersymmetric weak couplings to preserve unitarity of weak gauge boson scattering amplitudes to fermions, and derive sum rules for weak supersymmetric couplings.

description: Up to 60% of potable water supplied to Perth in Western Australia is extracted from the Gnangara mound. Many of the urban wetlands above the Mound are groundwater-dependent. Excessive groundwater extraction and climate change have resulted in a decline in water levels in the wetlands. This study estimates the value of urban wetlands in three local government districts in the Perth metropolitan region using the hedonic property price approach. Preliminary results found that proximity to wetlands influences the sales prices of properties. The marginal implicit price of reducing the distance to the nearest wetland by 1 metre, evaluated at the mean sales value, is AU$463. If there is more than one wetland within 1.5 kilometres of a property, the second wetland will help increase the property price by AU$6,081. For a 50 ha wetland, we estimate the total premium of on sales due to wetland proximity is AU$220 million, based on average property characteristics and medium house density. These results will help inform policy makers and land developers on the value of conserving existing urban wetlands, creating new wetland areas and urbanising rural wetlands.

description: The non-renewal of land leases since 1997 and the impending withdrawal of the European Union's sugar preferences in 2007 have created major uncertainties in Fiji's sugar industry. In the context of this troubled environment, this paper examines the impact of various socio-economic factors on the viability of the industry by focusing on farm efficiency in sugar cane production. It was found that, in general, farmers were inefficient and produced 25% less than their potential output. Among the farm inputs, land (labour) was relatively the most (least) efficiently used input. Empirical evidence also suggests that the more productive Indian farmers rather than the natives be left to farm cane and that large scale farming should be seriously considered by amalgamating land leases. Lastly, it is possible for Fiji's sugar industry to be sustained with the use of appropriate best farming techniques to improve cane yield, and if there is successful expansion of sugar-related products.

description: Over the past 220 years since European settlement, Australia has amassed a diverse array of historic heritage places. Currently there are approximately 200,000 places listed on statutory heritage lists across the nation. Owing to the public-good nature of heritage, community values for the preservation of historic places (both quality and quantity dimensions) is not readily observable from market transactions. Yet this information is critical for efficient management of heritage. This study uses a survey technique (Choice Modelling) to estimate value estimates. To the author's knowledge, it is the first study to use this approach to understand community preferences for alternative protection outcomes at a national level as opposed to site specific valuations.
Hybridization mechanism of the dual proximity effect in superconductor-topological insulator interfaces

Subjects: subject: Superconductivity (cond-mat.supr-con)

description: In this communication we consider generalities of the proximity effect in a contact between a conventional $s$-wave superconductor (S) nano-island and a thin film of a topological insulator (TI). A local hybridization coupling mechanism is considered and a corresponding model is corroborated that captures not only the induced unconventional superconductivity in a TI, but also predicts the spreading of topologically protected surface states into the superconducting over-layer. This dual nature of the proximity effect leads specifically to a modified description of topological superconductivity in these systems. Experimentally accessible signatures of this phenomenon are discussed in the context of scanning tunneling microscopy measurements. For this purpose an effective density of states is computed in both the superconductor and topological insulator. As a guiding example, practical applications are made for Nb islands deposited on a surface of Bi$_2$Se$_3$. The obtained results are general and can be applied beyond the particular material system used. Possible implications of these results to proximity circuits and hybrid hardware devices for quantum computation processing are discussed.

Η εκτίμηση αυτή βασίστηκε στους «στόχους στην εκπαίδευση του διαβήτη» που αποτελεί ένα ολοκληρωμένο εκπαιδευτικό πρόγραμμα μετάβασης της διαχείρισης του σακχαρώδη διαβήτη από τους γονείς και φροντιστές στα παιδιά και τους νέους. Η έρευνα είναι ποσοτική και στηρίχτηκε στις απαντήσεις των ερωτηματολογίων που μοιράστηκαν σε 6 ηλικιακές ομάδες μεταξύ 6 έως 18 ετών. Οι συμμετέχοντες ήταν 145 (100 γονείς και 45 ασθενείς/παιδιά) και συμπλήρωσαν τα ερωτηματολόγια τόσο οι γονείς όσο και τα παιδιά ηλικίας από 12 έως 18 ετών ξεχωριστά. Σύμφωνα με τα αποτελέσματα οι νέοι ηλικίας άνω των 12 ετών πιστεύουν ότι γνωρίζουν ικανοποιητικά. Οι γονείς των μικρών παιδιών είχαν μεγαλύτερη βαθμολογία γνώσεων συγκριτικά με τους γονείς των μεγαλύτερων παιδιών. Στοιχεία της οικογένειας όπως: η οικογενειακή κατάσταση, ο τόπος κατοικίας, το επάγγελμα και η εκπαίδευση των γονέων δεν επηρεάζουν σημαντικά το επίπεδο των γνώσεων σχετικά με την φροντίδα του διαβήτη, ωστόσο η επαρκής εκπαίδευση και η μεγαλύτερη βαθμολογία συσχετίζεται θετικά με μεγαλύτερη γλυκαιμική ρύθμιση. Συμπερασματικά, οι εκπαιδευτικές παρεμβάσεις έχουν ευεργετική επίδραση στο γλυκαιμικό έλεγχο των παιδιών και των εφήβων με διαβήτη.
description: The research focuses on the assessment of the knowledge of children and adolescents with diabetes type 1, regarding their own disease depending on their age and their cognitive maturity. This assessment was based on the «goals on diabetes education » which is a comprenhensive educational program of transition of the management of diabetes from the parents and caregivers for the children and youngsters. The research is quantitative and was based on the answers of the questionnaires that were given by 6 different age groups between 6 and 18 years of age. The participants were 145 (100 as parents and 45 kids/patients) and both parents and children filled out the questions, kids from age of 12 till 18 years did it separately. According to results, the youngsters over the age of 12 years believe that know it satisfactorily. The parents of the younger patients reported higher score of knowledge compared to the ones with older kids. Elements of the family like: family status, place of residency, occupation and the education level of the parents did not affect the level of knowledge regarding the caring of diabetes. However, higher scores were positively correlated to better glycemic control. In conclusion the educational interventions have positive effect on the glycemic control of the kids and adolescents with diabetes.
Global random walk solvers for fully coupled flow and transport in saturated/unsaturated porous media (extended version)

description: In this article, we present new random walk methods to solve flow and transport problems in unsaturated/saturated porous media, including coupled flow and transport processes in soils, heterogeneous systems modeled through random hydraulic conductivity and recharge fields, processes at the field and regional scales. The numerical schemes are based on global random walk algorithms (GRW) which approximate the solution by moving large numbers of computational particles on regular lattices according to specific random walk rules. To cope with the nonlinearity and the degeneracy of the Richards equation and of the coupled system, we implemented the GRW algorithms by employing linearization techniques similar to the $L$-scheme developed in finite element/volume approaches. The resulting GRW $L$-schemes converge with the number of iterations and provide numerical solutions that are first-order accurate in time and second-order in space. A remarkable property of the flow and transport GRW solutions is that they are practically free of numerical diffusion. The GRW solutions are validated by comparisons with mixed finite element and finite volume solutions in one- and two-dimensional benchmark problems. They include Richards' equation fully coupled with the advection-diffusion-reaction equation and capture the transition from unsaturated to saturated flow regimes. For completeness, we also consider decoupled flow and transport model problems for saturated aquifers.
Globalization and Canadian society : rhetoric or reality
Creators: name: Urmetzer, Peter Robert
Publisher: name: University of British Columbia
Year: 2009

description: Over the past decade, the topic of globalization has infiltrated both public and academic debates. The aim of this dissertation is to investigate whether the growth in the discussion of globalization is justified by an equivalent increase in the interaction of economies. The focus of this dissertation is on economic globalization and specifically how it affects Canada. Evidence of cross-border 'flows' is presented in three parts. One, the trade of goods is traced from Confederation (1867) to the present, showing that contemporary levels of trade are not unprecedented. Furthermore, the data reveal that the bulk of the increase in Canada's trade since the Second World War has been with the United States. There are also strong indications that as the economy is becoming more service oriented, it will also become less trade dependent. Two, statistics on foreign direct investment (FDI) reveal that foreign ownership in Canada is at an all-time historical low. Three, the stock of portfolio investments (stocks and bonds) owned across borders is also not, historically speaking, at particularly high levels. Overall, when foreign direct and portfolio investment are combined, the data show that only a small percentage of Canada's wealth is owned by foreign investors and, likewise, only a small portion of Canada's wealth is located outside of its borders. Another claim found in the globalization literature is that the nation state is weakening or disappearing altogether. However, once subjected to scrutiny, this claim, too, is difficult to sustain. Government expenditures have increased dramatically since the Second World War and show few signs of abating. For the fiscal year 1996/97, government expenditures amounted to approximately half of the Gross Domestic Product (GDP), indicating a general levelling of expenditures since the mid-1970s. More importantly, the globalization literature has unfailingly ignored the welfare-state side of government spending, arguably the most significant development in the political economy of the nation state in the 20th century. To bridge this gap, three sectors of the welfare state — education, health, and social services — are examined in detail. Lastly, an alternate explanation for globalization is put forward. Capital, it is argued, has made a concerted attack on the welfare state, utilizing high interest rates and high unemployment to discipline labour. Although having suffered a few scratches and dents as a consequence, the welfare-state has resolutely endured.

description: We examine the vitrification and melting of asymmetric star polymers mixtures by combining rheological measurements with mode coupling theory. We identify two types of glassy states, a {\it single} glass, in which the small component is fluid in the glassy matrix of the big one and a {\it double} glass, in which both components are vitrified. Addition of small star polymers leads to melting of {\it both} glasses and the melting curve has a non-monotonic dependence on the star-star size ratio. The phenomenon opens new ways for externally steering the rheological behavior of soft matter systems.

description: In a conservation auction there are many possible influences on bid prices. This paper considers a range of factors that influenced the bids submitted to the Queensland Government's Vegetation Incentives Program (VIP). The relationships between total bid price and a variety of variables are examined. The VIP appears to be a unique example of a program that asks landholders to separate management and covenant costs in their tender. Forgoing payment on the covenant may be an indicator of low opportunity cost or altruism on the part of the landholder. Accordingly this paper also investigates the influences on covenant bids.

description: Food companies are increasingly challenged to balance business performance and economic gains with environmental and social performance. Therefore, in 2012, we started a collaborative project on this topic named SCALE (Step Change in Agri-food Logistics Ecosystems). SCALE aims to improve the sustainability of food and drink supply chain logistics in the context of rising food demands, increasing energy prices and the need to reduce environmentally damaging emissions. More in particular, SCALE aims to deliver a number of tools and frameworks valuable for the agri-food sector to secure a step change in operational practices, which will improve the efficiency and sustainability of supply chain logistics. In the paper we present the first results of this project. Aim of this paper is (1) to present a sustainability research framework for food supply chains logistics including drivers, strategies, performance indicators, metrics and improvement opportunities to measure and potentially enhance sustainability performances; and (2) to analyse and diagnose the current status of Dutch food & drinks companies and logistics service providers using this framework. Results are found via a literature review, web-based research and structured interviews with Dutch food and logistics service industry.

description: Spherical data is distributed on the sphere. The data appears in various fields such as meteorology, biology, and natural language processing. However, a method for analysis of spherical data does not develop enough yet. One of the important issues is an estimation of the number of clusters in spherical data. To address the issue, I propose a new method called the Spherical X-means (SX-means) that can estimate the number of clusters on d-dimensional sphere. The SX-means is the model-based method assuming that the data is generated from a mixture of von Mises-Fisher distributions. The present paper explains the proposed method and shows its performance of estimation of the number of clusters.
Pakistan: Still ‘Under Increased Monitoring’ of FATF

description: There is a great deal of disappointment in Pakistan with the Financial Action Task Force (FATF), a Paris-based global money laundering watchdog, having resolved to put Pakistan again on its terrorism financing list of “Jurisdictions Under Increased Monitoring” (JUIM)—often referred to as the ‘grey list.’ Pakistan figured in the list of 19 countries, identified under JUIM, at the recently concluded meeting of FATF. These countries (which also included India’s another neighbour, Myanmar) were acknowledged as having failed to tackle terror financing. The decision of the FATF has come as a setback to Islamabad at a critical juncture when the country is reeling under tremendous economic pressure.

PI architectures

description: The rapid advancement in data center processing speeds, driven by Artificial Intelligence (AI) and Machine Learning (ML) applications, necessitates high-frequency operation of wireline clock and data recovery (CDR) systems. This evolution demands low-power, high-resolution phase interpolators (PIs) in clocking circuits to precisely eliminate phase and frequency offsets between receivers and transmitters. Additionally, as data rates escalate in wireless communications, transmitted signals become increasingly vulnerable to interference, necessitating beamforming or beam steering techniques. An increase in the number of channels enhances the signal-to-noise ratio (SNR) at the receiver output
description: but also requires more PIs, potentially escalating power consumption and compromising the efficiency of the beamforming system. Therefore, the development of low-power PIs is critical for enabling efficient beamforming at higher frequencies.
description: This dissertation presents two novel PI architectures designed to address these critical challenges. The first architecture is a constant slope and swing ramp-based PI designed for baseband beamforming delay compensation. This PI, implemented in TSMC-65nm CMOS, is both linear and low-power, with a power efficiency of 0.312 mW/GHz. It can operate at frequencies up to 1.6 GHz and compensate for signal delays with bandwidths up to 800 MHz. However, its low swing slope signal ramp-signal induces more noise, resulting in jitter of 412 fs. The second architecture is a DC-modulated ramp-based PI, which significantly increases the operating speed to 12 GHz- seven times that of the first PI architecture. This low-power PI implemented in 65nm CMOS shows a power efficiency of 0.18 mW/GHz. This PI can directly generate 4-phase PI outputs at clock frequencies up to 6 GHz without requiring a delay-locked loop (DLL) or quad generator at the input side, making it a most compatible low power clocking solution for CDR applications. Additionally, it contributes to minimum noise at the output with jitter of 68fs only.
description: The third contribution of this dissertation is the design of a low-power, compact analog sub-sampling phase-locked loop (SS-PLL) using a capacitor-multiplier circuit to reduce the area of the loop filter and the overall PLL footprint. This approach offers superior phase noise performance compared to digital PLLs, presenting a promising solution for high-performance RF transceivers in 5G communication systems.

description: We have measured the influence of shot noise on hysteretic Josephson junctions initially in macroscopic quantum tunnelling (MQT) regime. Escape threshold current into the resistive state decreases monotonically with increasing average current through the scattering conductor, which is another tunnel junction. Escape is predominantly determined by excitation due to the wide-band shot noise. This process is equivalent to thermal activation (TA) over the barrier at temperatures up to about four times above the critical temperature of the superconductor. The presented TA model is in excellent agreement with the experimental results.

Institutional Change in Germany’s Farmers Associations: Impacts of the Dairy Conflict
Creators: name: Alpmann, Jan

Publisher: name: CentMA
Year: 2013
Subjects: dairy conflict; farmer associations; grounded theory; institutional change; milk strike

description: The abolishment of the milk quota, increasing fluctuation in milk prices and further economic and emotional factors resulted in the so called dairy conflict. The paper focuses specifically on the conflict between the German Farmers’ Association and the Federal Dairy Farmers Association resulting in two milk delivery strikes as culmination points within the conflict. Objectives of the study were to analyze the main conflict indicators, the conflict pattern and the process of change in the agricultural association structure in Germany. The basic methodology is a qualitative research approach. Main data collection methods are in-depth interviews and qualitative document analysis. Results show a high cross-linking between the abolishment of the milk quota and identified emotional key drivers. Structural consequences of this conflict can be seen in the reduction of political influence of the German Farmers’ Association.

Does the Sustainability of Food Products Influence Consumer Choices? The Case of Italy
Creators: name: Banterle, Alessandro

Year: 2013
Subjects: Consumer choices; environmental sustainability; food labelling

description: In this paper we analyse if there is a diffused interest among consumers about the environmental impacts of their food choices, and try to capture the different types of attitudes of Italian consumers with respect to environmental sustainability of food products. The analysis builds on a survey based on vis-a-vis interviews with 240 consumers in Milan, and on a cluster analysis. The results highlight a high level of stated concern about environmental issues and about possible impacts of personal food consumption choices on the environment. Nevertheless, when investigating their actions during everyday shopping we have identified four groups of consumers: (1) those who take into consideration the environmental information on labels and do not require additional information; (2) those for which environmental information on labels does not have a great effect on purchase, but would like to receive more information; (3) those for which the presence of environmental information directs product selection and would also like to receive more; (4) those that do not take into account environmental issues when purchasing and are not interested in receiving more information about the impacts of the products.

description: We present a method that accurately propagates residual uncertainties in photometric redshift distributions into the cosmological inference from weak lensing measurements. The redshift distributions of tomographic redshift bins are parameterised using a flexible modified Gaussian mixture model. We fit this model to pre-calibrated redshift distributions and implement an analytic marginalisation over the potentially several hundred redshift nuisance parameters in the weak lensing likelihood, which is demonstrated to accurately recover the cosmological posterior. By iteratively fitting cosmological and nuisance parameters arising from the redshift distribution model, we perform a self-calibration of the redshift distributions via the tomographic cosmic shear measurements. Our method is applied to the third data release of the Kilo-Degree Survey combined with the VISTA Kilo-Degree Infrared Galaxy Survey (KV450). We find constraints on cosmological parameters that are in very good agreement with the fiducial KV450 cosmic shear analysis and investigate the effects of the more flexible model on the self-calibrated redshift distributions. We observe posterior shifts of the medians of the five tomographic redshift distributions of up to $Δz \approx 0.02$, which are however degenerate with an observed decrease of the amplitude of intrinsic galaxy alignments by about $10\%$.
