Risk and Uncertainty

description: In 2007 five different industrial food producers merged to become one single firm. This paper places focus on the challenge these actors had in deciding on, implementing, and using an information system to support mainly their raw material purchasing and finished product sales function. Studies show that a large part of information system implementation failures are related to insufficient alignment between various aspects or parts of an organization and the new technology (Miller 2001, Wognum 2004). A report of a working group from The Royal Academy of Engineering and The British Computer Society concerning the challenges of complex IT project (RAEng, 2004) supports this view stating that the most pressing problems are related to the human aspect of processes involved in these kinds of projects, and that further developments in methods and tools to support the design and delivery of such projects could help to raise success rates. Among key findings of this study were: • The levels of professionalism observed in software engineering are generally lower than those in other branches of engineering, although there are exceptions • Senior managers are often ill qualified to handle issues relating to complex IT projects • The importance of project management is not well understood and usually underrated • The vital role of the systems architects in major IT projects is frequently not appreciated and there is a shortage of appropriately skilled individuals • Basic research into complexity and associated issues is required to enable the effective development of complex, globally distributed systems

description: We demonstrate how the 5G network slicing model can be extended to address data security requirements. In this work we demonstrate two different slice configurations, with different encryption requirements, representing two diverse use-cases for 5G networking: namely, an enterprise application hosted at a metro network site, and a content delivery network. We create a modified software-defined networking (SDN) orchestrator which calculates and provisions network slices according to the requirements, including encryption backed by quantum key distribution (QKD), or other methods. Slices are automatically provisioned by SDN orchestration of network resources, allowing selection of encrypted links as appropriate, including those which use standard Diffie-Hellman key exchange, QKD and quantum-resistant algorithms (QRAs), as well as no encryption at all. We show that the set-up and tear-down times of the network slices takes of the order of 1-2 minutes, which is an order of magnitude improvement over manually provisioning a link today.

description: The world food crisis has brought about heated discussions on policy responses and actions to achieve future stability and security in food consumption for the poor. While many viewing it as a supply proglem and propose to cope with it by incrasing self-supply, there are also propostitions of viewing it more as an income problem. This paper has taken the experience of China into study. Being the most populous nation in the world and with rural low-income and low food consumption groups still a noticeable portion in the rural area, China has devoted strenuous efforts by utilizing various policy approaches. This paper has estimated empirically the impact of different policy measures, i.e., the predominantly used traditional policy aimed at increasing self-production locally, the “supply” approach, and the pro-market approach of increasing income to purchase more food from market, the “income” approach, on the improvement of food security in disadvantageous regions in rural China, Both Provincial and household data are used in the research, with particular attention paid to regions characterized by low income and low grain production. The results show that with the county’s transition into market system, higher ratio of grain sown area to total cultivate area, as advocated by grain self-sufficiency policy, would hardly lead to improved grain and food consumption for disadvantageous farmers in less-favored regions. On the contrary, it might lead to a worsened food security situation. The increase of income, on the other hand, will help farmers in poor and grain insufficient regions to improve their food security status. It is hoped that the experience from China will help to provide additional evidence for the discussion of policy alternatives for food security for other developing countries.

description: Present-day electric power distribution grid faces multiple challenges in maintaining high power quality standards. This dissertation aims to examine and design modern distribution grid topologies that can provide reliable power service to customers at all times. One of the recent challenges in distribution grids is imposed by increased residential PV integration. A detailed analysis on its impacts on different grids is conducted and a generalization on factors that affect high PV integration in distribution grid is provided. Based on the study, an optimization framework is proposed to design distribution grid topologies with high PV hosting capacity, while maintaining the required power quality standards. Furthermore, new topologies are designed for networks with high resiliency needs. In this work, a specific application of electric ship networks that are commissioned for military use is studied in detail, but the design approach is applicable for other networks as well. Finally, a reduced-scale hardware test-bed design for distribution grid analysis with distributed energy resources like PV, storage and capacitors is described in this dissertation. As a part of the hardware development, a novel programmable load model that can provide variable fundamental and harmonic load characteristics is proposed

description: We study the thermodynamical properties of a self-gravitating gas with two or more types of particles. Using the method of linear series of equilibria, we determine the structure and stability of statistical equilibrium states in both microcanonical and canonical ensembles. We show how the critical temperature (Jeans instability) and the critical energy (Antonov instability) depend on the relative mass of the particles and on the dimension of space. We then study the dynamical evolution of a multi-components gas of self-gravitating Brownian particles in the canonical ensemble. Self-similar solutions describing the collapse below the critical temperature are obtained analytically. We find particle segregation, with the scaling profile of the slowest collapsing particles decaying with a non universal exponent that we compute perturbatively in different limits. These results are compared with numerical simulations of the two-species Smoluchowski-Poisson system. Our model of self-attracting Brownian particles also describes the chemotactic aggregation of a multi-species system of bacteria in biology.

description: This paper explores the relevance of food origin to consumers when making product purchase decisions. We use data from a survey of pork shoppers at the point of sale of five food retailers in Germany. Participants engaged in both a hypothetical survey eliciting evaluations of the importance of different pork attributes and a series of questions related to their knowledge about the attributes of their actual purchase of pork. This enables us to compare hypothetical responses with actual purchase behavior. The results show that origin indeed is a relevant attribute to a subset of consumers. A share of consumers does pay attention to origin labels and is willing to undertake costly search for origin information. Furthermore, the data give evidence that there is a strong, but not perfect, degree of agreement between hypothetical survey responses and actual shopping behavior. This result is supportive of the use of experimental methods.

description: This paper develops a method to jointly estimate crop yield elasticities and area elasticities with respect to output prices based on a theoretically consistent model. The model uses a duality theory approach for the multi-output and multi-input firm, and introduces uncertainty in the level of target output which conditions the cost minimization problem, in the output prices and in the conditional input demand functions. The underlying production technology is conditioned on fixed inputs, both allocatable and non-allocatable. Up to our knowledge, there have been no theoretical developments of this type of models for multioutput technologies. Our approach is also novel because no previous model of this type has introduced the effects of allocatable fixed inputs. We provide an empirical application of this theoretical framework using State-level data and approximating the dual cost function by a normalized quadratic flexible functional form. We derive expressions for the elasticities of interest conditional on the function specification assumed.

description: We apply a spatial price equilibrium model of the world sugar market to simulate an abolishment of the EU quota system in 2015/16. To overcome the normative nature of the approach, we calibrate the model by attaching a non-linear cost term to each trade flow. This is in some regards similar to positive mathematical programming. We suggest an economic interpretation and an econometric specification of the cost term. Production in the EU increases to almost 16 million tons. Twelve member states increase production, seven reduce it. Preferential imports are significantly reduced. Simulated effects are found to be more pronounced the higher the world market price.

description: Conventional existing retrieval methods in remote sensing (RS) are often based on a uni-modal data retrieval framework. In this work, we propose a novel inter-modal triplet-based zero-shot retrieval scheme utilizing a sketch-based representation of RS data. The proposed scheme performs efficiently even when the sketch representations are marginally prototypical of the image. We conducted experiments on a new bi-modal image-sketch dataset called Earth on Canvas (EoC) conceived during this study. We perform a thorough bench-marking of this dataset and demonstrate that the proposed network outperforms other state-of-the-art methods for zero-shot sketch-based retrieval framework in remote sensing.

First, the mean number $N(R)$ of LRGs within completely surveyed LRG-centered spheres of comoving radius $R$ is shown to be proportional to $R^3$ at radii greater than $R\sim 70 h^{-1} \mathrm{Mpc}$. The test has the virtue that it does not rely on the assumption that the LRG sample has a finite mean density; its results show, however, that there \emph{is} such a mean density. Secondly, the survey sky area is divided into 10 disjoint solid angular regions and the fractional rms density variations of the LRG sample in the redshift range $0.2

description: This paper analyses how farm access to credit affects farm input allocation and farm efficiency in the CEE countries. Drawing on a unique farm level panel data with 37,409 observations and employing a matching estimator we are able to control for the key source of endogeneity – unoberserved heterogeneity. We find that farms are credit constrained both in the short-run as well as in the long-run, but that credit constraint is asymmetric between inputs. Our estimates suggest that farm access to credit increases TFP up to 1.9% per 1000 EUR of additional credit. The use of variable inputs and capital investment increases up to 2.3% and 29%, respectively, per 1000 EUR of additional credit. Due to credit-financed investment in labour-saving farm equipment, labour use reduces for low level of credit Farms are found not to be credit constrained with respect to land.

description: Over the last decades, the number of farms has decreased while average farm size has increased in industrialised countries. We investigate whether these two concomitant trends have resulted in higher farmland concentration or not in the case of France. Deriving Gini coefficients as a measure of concentration from the estimation of parametric Lorenz curves, we show that this is not systematically the case at the sub-national scale of “départements”. When studying the role of possible explanatory variables for farmland concentration, we find that milk quotas, CAP 2nd pillar subsidies and so-called structural measures (settlements and early retirement grants) have a significant impact. However, the availability and the price of agricultural land appear to be the most significant factors.

description: This paper presents a dynamic theory of structural change in which functional change driven by technological change and transactional change open opportunity for change in scale and scope of enterprises. Implementation of change in scale and scope of enterprises is constrained by initial state conditions including resource endowments, access to credit, and regulation. In the presence of such constraints, the paper motivates the existence of thresholds that introduce cusps in the optimal paths of control variables. The evolution of enterprises is considered within the context of a multiple enterprise firm that encompasses discrete and continuous processes that are interdependent on intermediate goods as well as their production of environmental effects. Response to opportunity is governed as well by adjustment costs and incomplete markets. The specification is consistent with manufacturing, crop and animal agriculture, as well as service-oriented enterprises. Potential for structural change is considered within the context of changes in prices, regulation, and technological change. We discuss management options that maximize uncertain profit over the planning horizon subject to changing price regimes, regulations, and existing and new technology. We consider incentive as well as quota type policy to regulate environmental effects. While the model is one of optimal control, the presence of constraints opens the opportunity for timing of adjustment and constrains adjustment. We derive thresholds for change and show their principal determinants. Based on this specification, we derive an indicator of flexibility as well as real options style valuation of the benefits of postponement of adjustment. The model’s specification is sufficiently complex as to preempt analytical consideration. Instead, we specify a numerical example and present illustration of the implications of the model based on numerical computation. The example illustrates both unbundling of enterprises as conditions encourage reduction in scope as well as formation of relational links to recover what might be viewed as economies-of-scale by specialized enterprises spawned by unbundling. The example also illustrates conditions necessary to induce a shift from traditional grazing animal operations integrated with crops to intensive feed lots. Within this context, shift in scale, specialization, and scope of enterprises is illustrated. To conclude, the utility of model is considered within general contexts to analyze the structural implications of change in economic conditions such as shifts in price regimes, change in process technology, change in IT technology, and changes in institutional rules.

description: Samples of Y0.4Pr0.6Ba2-xSrxCu3O7 have been synthesized by a solid- state reaction route. The samples with x = 0.60 crystallize in an orthorhombic structure (with orthorhombic distortion decreasing with increasing x), while the samples with x=0.80 and 1.0 crystallize in a pseudo tetragonal structure. Resistance (R) measurements as a function of temperature (T) show that x = 0.0 sample is highly semiconducting with R2K/R300K ratio of ~ 65. This ratio decreases to only ~23 and 5 for x=0.20 and x=0.4 samples, respectively. Further, the x=0.60 sample shows onset of a broad superconducting transition temperature (Tconset) at around 20 K without achieving the TcR=0 state down to 2 K. The TcR=0 state is observed in x = 0.80 and 1.00 samples at around 5 and 14 K, respectively. Thermo-electric power (S), also exhibits TcS~0 state at around 11 K and 16 K, respectively for x = 0.8 and 1.00 samples. Thermo electric power at room temperature is positive and decreases with increasing x, indicating enhanced number of mobile holes. These results demonstrate that substitution of Sr at Ba-site systematically induces metallicity and eventually superconductivity in Y0.4Pr0.6Ba2-xSrxCu3O7 system. The results are explained on the basis of reduced Pr(4f) orbital hybridization with O(2p) in supercondu cting Cu-O2 planes, resulting in delocalization of the mobile carriers. The role of decreased Pr/Ba intermixing disorder is also considered.

description: BACKGROUND The strategic selection and application of effective cognitive learning strategies as part of self-regulated learning contributes to long-term retention of learned materials and potential transfer of knowledge (Dunlosky et al., 2013; Fiorella & Mayer, 2016). However, research shows that, when higher education students make self-regulated decisions about their learning, they often do not choose effective cognitive strategies (Carpenter, 2023). As a result, recent years have seen an increase in multifaceted interventions that show promise for supporting students’ use of effective cognitive learning strategies (Carpenter, 2023; McDaniel & Einstein, 2023). PURPOSE These multidimensional interventions are often resource-intensive, and run parallel to existing educational activities without supporting students in the application of newly acquired learning strategies in the learning context of their content courses. In addition, student motivation for effective strategy use in relation to students’ learning goals does not play a central role in current interventions. This dissertation addressed these two issues.FINDINGS Two experiments which contained compact strategy intervention embedded into higher education course modules demonstrated that strategy instructions alone and strategy instructions together with metacognitive support can increase the self-regulated use of retrieval practice in real world learning situations. Second, a qualitative study and an experiment with an embedded learning strategy intervention showed that students already make regular use of effective cognitive learning strategies often in combination with other surface-level strategies, and possess basic strategy knowledge. Third, it was found that a crucial motivational factor that contributes to effective cognitive strategy use is the perceived utility value of a learning strategy in relation to students’ learning goals.CONCLUSION Important implications are that effective strategy use can be supported with compact strategy interventions in authentic learnIng environments. These findings also imply that it may be potentially feasible and effective to build upon students’ current use of effective cognitive strategies (Miyatsu et al., 2018), for example with the aid of different types of co-regulation. Last, assuming that when students are able to attribute value to learning strategies and to what they are learning content-wise, they may be more likely to engage in active ways of learning, such as using effective cognitive strategies.

description: This is the first paper to study job creation and destruction in EU agriculture. We disaggregate employment patterns and job flows into detailed intra-sectoral labour adjustment dynamics based on farm level panel observations from 1989-2006. We find that: (1) job creation and destruction rates in EU agriculture are high compared to other sectors; (2) there are important differences in job creation and destruction rates between different member states; (3) this can be attributed to differing initial farm structures: member states with small average farm sizes display higher job creation and destruction rates than those with larger average farm sizes.

description: We present the afterglow light curves produced by the deceleration of the non-relativistic ejecta mass in a stratified circumstellar medium with a density profile $n(r)\propto r^{-k}$ with $k=0$, $1$, $1.5$, $2$ and $2.5$. Once the ejecta mass is launched with equivalent kinetic energy parametrized by $E(>β)\propto β^{-α}$ (where beta is the ejecta velocity) and propagates into the surrounding circumstellar medium, it first moves with constant velocity (the free-coasting phase), and later it decelerates (the Sedov-Taylor expansion). We present the predicted synchrotron and synchrotron-self Compton light curves during the free-coasting phase, and the subsequent Sedov-Taylor expansion. In particular cases, we show the corresponding light curves generated by the deceleration of several ejecta masses with different velocities launched during the coalescence of binary compact objects and the core-collapse of dying massive stars which will contribute at distinct timescales, frequencies, and intensities. Finally, using the multi-wavelength observations and upper limits collected by a large campaign of orbiting satellites and ground telescopes, we constrain the parameter space of both the KN afterglow in GW170817 and the possibly generated KN afterglow in S190814bv. Further observations on timescales of years post-merger are needed to derive tighter constraints.

However, the practical limits to weak lensing observations are not known. Most theoretical studies of weak lensing constraints on cosmology assume that the only limits are shot noise on small scales, and cosmic variance on large scales. For future large surveys, shot noise will be so low that other, systematic errors will likely dominate. Here we examine a potential source of additive systematic error for ground-based observations: spurious power induced by the atmosphere. We show that this limit will not be a significant factor even in future massive surveys such as LSST.

description: We examine one overlooked in previous investigations aspect of well - known Landau - Zener (LZ) problem, namely, the behavior in the intermediate, i.e. close to a crossing point, energy region, when all four LZ states are coupled and should be taken into account. We calculate the 4 x 4 connection matrix in this intermediate energy region, possessing the same block structure as the known connection matrices for the tunneling and in the over-barrier regions of the energy, and continously matching those in the corresponding energy regions.

description: We show that any Littlewood--Paley square function $S$ satisfying a minimal local testing condition is dominated by a sparse form, \begin{equation*} \langle (Sf)^2,g \rangle\le C \sum_{I \in \mathscr{S}} \langle \lvert f\rvert\rangle_I^2 \langle \lvert g\rvert\rangle_I \lvert I\rvert . \end{equation*} This implies strong weighted $L^p$ estimates for all $A_p$ weights with sharp dependence on the $A_p$ characteristic. The proof uses random dyadic grids, decomposition in the Haar basis, and a stopping time argument.

description: Drawing on the Big Middle theory of retail evolution, an analysis of primary survey data on Thai shopping behavior seeks to understand the relative satisfaction of consumers with wet markets and supermarkets, identifying the factors that affect frequency of visit to, and purchase behavior within, these retail outlets. This provides the basis for engaging in a wider debate on the possibility of a ‘Global Big Middle’ for food retailing. On all salient attributes affecting retail outlet choice, supermarkets perform better than wet markets. However for fresh produce, wet markets continue to account for the majority of expenditure, albeit to a far lesser extent than in previous studies. A bootstrapped bivariate ordered probit model identifies that supermarkets are frequented more by higher educated and younger consumers in the capital city but penetration of supermarkets is high for all socio-economic groups. Bootstrapped bivariate Tobit models reveal supermarkets’ share of fresh produce expenditure is neither biased to a particular educational group nor related to age or, with exception of fresh meat, household income. The analysis questions previous work which perceived wet markets in east Asia as possessing a long-term competitive advantage in food retailing.
On classification of normal operators in real spaces with indefinite scalar product

description: A real finite-dimensional space with indefinite scalar product having v- negative squares and v+ positive ones is considered. The paper presents a classification of operators that are normal with respect to this product for the cases min{v-, v+} = 1, 2. The approach used here was developed in papers by Gohberg and Reichstein and by the authors, where a similar classification was obtained for complex spaces with v = min{v-,v+} = 1, 2, respectively.

Neutrino amplitude decomposition: Toward observing the atmospheric - solar wave interference

description: Observation of the interference between the atmospheric and solar oscillation waves with the correct magnitude would provide another manifestation of the three-generation structure of leptons. As a prerequisite for such analyses we develop a method for decomposing the oscillation $S$ matrix into the atmospheric and solar amplitudes. Though the similar method was recently proposed successfully in vacuum, once an extension into the matter environment is attempted, it poses highly nontrivial problems. Even for an infinitesimal matter potential, inherent mixture of the atmospheric and solar oscillation waves occurs, rendering a simple extension of the vacuum definition untenable. We utilize general kinematic structure as well as analyses of the five perturbative frameworks, in which the nature of matter-dressed atmospheric and solar oscillations are known, to understand the origin of the trouble, how to deal with the difficulty, and to grasp the principle of decomposition. Then, we derive the amplitude decomposition formulas in these frameworks, and discuss properties of the decomposed probabilities. We mostly discuss the $ν_μ \rightarrow ν_{e}$ channel, but a comparison with the $ν_μ \rightarrow ν_τ$ channel reveals an interesting difference.

description: Food manufacturers have an incentive to include nutrient content claims, health claims, or other types of labeling statements on foods if they believe that consumers will be willing to pay more for products with specific attributes. We estimated semi-log hedonic price regressions for five breakfast bar and cereal product categories using Nielsen ScanTrack scanner data for 2004 and found that labeling statements for these foods are often associated with substantial increases in consumer willingness to pay. The largest effects were associated with “carb-conscious” carbohydrate labeling (reflecting the time period of the data), followed by fat and sugar content labeling statements.
Connecting Relaxation Time to a Dynamical Length Scale in Athermal Active Glass Formers

description: Supercooled liquids display dynamics that are inherently heterogeneous in space. This essentially means that at temperatures below the melting point, particle dynamics in certain regions of the liquid can be orders of magnitude faster than other regions. Often dubbed as dynamical heterogeneity, this behavior has fascinated researchers involved in the study of glass transition, for over two decades. A fundamentally important question in all glass transition studies is whether one can connect the growing relaxation time to a concomitantly growing length scale. In this paper, we go beyond the realm of ordinary glass forming liquids and study the origin of a growing dynamical length scale $ξ$ in a self propelled "active" glass former. This length scale which is constructed using structural correlations agrees well with the average size of the clusters of slow moving particles that are formed as the liquid becomes spatially heterogeneous. We further report that the concomitantly growing $α$- relaxation time exhibits a simple scaling law, $τ_α\sim \text{exp} (ξμ/ T_{eff})$, with $μ$ as an effective chemical potential, $T_{eff}$ as the effective temperature, and $ξμ$ as the growing free energy barrier for cluster rearrangements. The findings of our study are valid over three decades of persistence times, and hence could be very useful in understanding the slow dynamics of a generic active liquid such as an active colloidal suspension, or a self propelled granular medium, to mention a few.

description: Traditional economic theory posits that a well functioning capital market is a necessary condition for industrialization and economic growth. However, in reality it is observed that micro and small enterprises are ubiquitous because entrepreneurs can set up business in low-return activities with minimal barriers to entry. Using a cashmere sweater cluster in China as an example, this paper shows that organizational choice can overcome the prohibitive cost of investment. Facing credit constraints, firms are more likely to concentrate in divisible production technologies in the form of industrial clusters. With clusters, a vertically integrated production process can be decomposed into many small incremental stages, making them more accessible for small entrepreneurs widely available in rural China, even without a well functioning capital market. The observed rate of returns to capital is closely related to the organizational choice under credit constraints.
