Inter-organizational Trust and Authenticity in Supply Chain: Cross-national Research in Restaurants at Germany and Italy
Creators: name: De Almeida, Luciana Florêncio
Publisher: name: Proceedings in Food System Dynamics
Year: 2020

description: In the literature on contracts and hybrids forms, there is an established discussion of minimizing ex-post and ex-ante risks in trading between partners (Menard, 2004; Gullati, 1995; Williamson, 1996). There is a quest to align interests so that both parties can be winners. Specifically, inter-organizational trust in supply chain relationships is supported as a key element in this alignment which can lead to direct economic outcomes, indirect outcomes or relational outcomes such as loyalty, joint responsibility, purchasing cost reduction, among others (Delbufallo, 2012). Nevertheless, the existent literature had not addressed authenticity as a direct outcome of inter-organizational trust in supply chain relationships. This paper proposes a theoretical framework that conceptualizes authenticity as a result of strategic alignment between trading partners based on inter-organizational trust. As en empirical illustration and a test for the proposed framework, the relationship between restaurants and their food suppliers was investigated and analyzed.

description: Mahotas is a computer vision library for Python. It contains traditional image processing functionality such as filtering and morphological operations as well as more modern computer vision functions for feature computation, including interest point detection and local descriptors. The interface is in Python, a dynamic programming language, which is very appropriate for fast development, but the algorithms are implemented in C++ and are tuned for speed. The library is designed to fit in with the scientific software ecosystem in this language and can leverage the existing infrastructure developed in that language. Mahotas is released under a liberal open source license (MIT License) and is available from (http://github.com/luispedro/mahotas) and from the Python Package Index (http://pypi.python.org/pypi/mahotas).

Bridging the ensemble Kalman and particle filter

Subjects: subject: Methodology (stat.ME)

description: In many applications of Monte Carlo nonlinear filtering, the propagation step is computationally expensive, and hence, the sample size is limited. With small sample sizes, the update step becomes crucial. Particle filtering suffers from the well-known problem of sample degeneracy. Ensemble Kalman filtering avoids this, at the expense of treating non-Gaussian features of the forecast distribution incorrectly. Here we introduce a procedure which makes a continuous transition indexed by gamma in [0,1] between the ensemble and the particle filter update. We propose automatic choices of the parameter gamma such that the update stays as close as possible to the particle filter update subject to avoiding degeneracy. In various examples, we show that this procedure leads to updates which are able to handle non-Gaussian features of the prediction sample even in high-dimensional situations.

description: In this work we make a systematic analysis of the correlated processes $J/ψ\to γη(1440)/f_1(1420)$ with $η(1440)/f_1(1420)\to K\bar{K}π$, $ηππ$ and $3π$, where the role played by the so-called "triangle singularity mechanism" (TSM) is clarified. Our results agree well with the experimental data and suggest a small fraction of $f_1(1420)$ contributions in these processes. This study confirms our conclusion in [Phys. Rev. Lett. 108, 081803 (2012)] that the dynamic feature of the TSM can be recognized by the strong narrow peak observed in the $ππ$ invariant mass spectrum of $η(1440)\to 3π$ with anomalously large isospin violations. Nevertheless, we explicitly demonstrate that the TSM can produce obvious peak position shifts for the same $η(1440)$ or $f_1(1420)$ state in different decay channels. This is a strong evidence that the $η(1405)$ and $η(1475)$ are actually the same state, i.e. $η(1440)$. We also make an analysis of the radiative decays of $η(1440)\to γV$ ($V=ϕ$, $ρ^0$ or $ω$) which shows that such a one-state prescription seems not to have a conflict with the so-far existing experimental data. Our analysis may shed a light on the long-standing puzzling question on the nature of $η(1405)$ and $η(1475)$.

Year: 2020

description: Appropriate value creation processes play a key role in the success of organic food supply chains in terms of effective response to consumer requirements and sustainability goals. In this study, we explore key drivers for value creation in the organic food industry, taking the Spanish organic olive supply chain as a representative case study. A business model survey was conducted with the participation of a highly qualified panel of experts to provide innovative options for value generation in the organic olive oil industry. Elicited expert judgements relate to the identification of the potential sources of adding value along the supply chain as a whole and among its different actors, as well as the factors that influence positively and negatively the adding-value formation. Findings contribute new ideas and pathways to develop innovative, effective and sustainable business models capable to generate value for companies, customers and the society as a whole. Results can be readily applied in real-world case studies to improve existing company business models.

With the analysis of these inventories of the typical needs of the SFSCs and the solutions, such patterns of strengths and weaknesses can be established, which can be used for the identification of the typical bottlenecks and potential success factors of SFSCs. The rapid development of digital technologies provides a range of new enabling functions of solutions, which can be adapted for SFSCs.

description: We present results of transverse acoustics studies in superfluid ^{3}He-B at fields up to 0.11 T. Using acoustic cavity interferometry, we observe the Acoustic Faraday Effect for a transverse sound wave propagating along the magnetic field, and we measure Faraday rotations of the polarization as large as 1710^{\circ}. We use these results to determine the Zeeman splitting of the Imaginary Squashing mode, an order parameter collective mode with total angular momentum J=2. We show that the pairing interaction in the f-wave channel is attractive at a pressure of P=6 bar. We also report nonlinear field dependence of the Faraday rotation at frequencies substantially above the mode frequency not accounted for in the theory of the transverse acoustic dispersion relation formulated for frequencies near the mode. Consequently, we have identified the region of validity of the theory allowing us to make corrections to the analysis of Faraday rotation experiments performed in earlier work.

description: Using the optical spectrum obtained with the Kitt Peak Ohio State Multi-Object Spectrograph (KOSMOS) mounted on the Apache Point Observatory (APO) 3.5m Telescope and the Sloan Digital Sky Survey (SDSS) spectrum, we study the properties of one of the most metal-poor dwarf star-forming galaxies (SFG) in the local Universe, J1046+4047. The galaxy, with a redshift z=0.0487, was selected from the Data Release 16 (DR16) of the SDSS. Its properties are among the most extreme for SFGs in several ways. Its oxygen abundance 12+log(O/H) = 7.091+/-0.016 is among the lowest ever observed. With an absolute magnitude Mg = -16.51 mag, a low stellar mass Mstar = 1.8x10^6 Msun and a very low mass-to-light ratio Mstar/Lg~0.0029 (in solar units), J1046+4047 has a very high specific star-formation rate sSFR~430 Gyr^-1, indicating very active ongoing star formation. Another striking feature of J1046+4047 is that it possesses a ratio O32 = I([OIII]5007)/I([OII]3727) ~57. Using this extremely high O32, we have confirmed and improved the strong-line calibration for the determination of oxygen abundances in the most metal-deficient galaxies, in the range 12+log(O/H) < 7.65. This improved method is appropriate for all galaxies with O32<60 and extends an applicability to highest observed O32 ratios.We find the Halpha emission line in J1046+4047 to be enhanced by some non-recombination processes and thus can not be used for the determination of interstellar extinction.

description: We report the experimental and theoretical study of two-body interactions in a $^{6}$Li-$^{133}$Cs Fermi- Bose mixture. Using a translatable dipole trap setup, we have successfully trapped the two species in the same trap with temperatures of a few microkelvins. By monitoring atom number loss and inter-species thermalization, we identify five s-wave interspecies Feshbach resonances in the lowest two scattering channels. We construct a coupled channels model using molecular potentials to fit and characterize these resonances. Two of the resonances are as wide as 60 G and thus should be suitable for creating Feshbach molecules and searching for universal few-body scaling.

description: The Anadara tuberculosa in Ecuador called "Concha Prieta", is a bivalve mollusk that is obtained manually on the shores of the American Pacific Ocean, from northern Peru to southern Mexico. This artisanal business economically and socially benefits thousands of fishing families but also contributes significantly to the preservation of the mangrove swamp, one of the main ecosystems that produce blue carbon. The objective of this research was to characterize the management of agribusiness and the performance of the Anadara tuberculosa value chain. It was concluded that despite the low levels of agribusiness management, the performance of the value chain reaches an intermediate level, mainly due to the relevant characteristics of the Concha Prieta, the high demand in the Ecuadorian market and in neighboring countries.

title: Generation Of Plasma with a Rotating Electric Field
Creators: name: Mosely, Franklin Price
Publisher: name: Old Dominion University Libraries
Year: 2023

description: Nonthermal plasma generation is an important area of research that has many applications ranging from semiconductor production to medical applications including the treatment of cancers and sterilization of surfaces. Specific radicals and excited species and discharge powers are critical for the successful completion of these processes. It is important that these excited species are shown to be achievable for a given discharge system without leading to instabilities such as arcing.

The present thesis details the design, fabrication, testing, and analysis of a novel plasma generation system based on multiphase excitation. As predicted by theory, the experimental results demonstrate that a stable plasma can be generated using a rotating electric field. Results show that the average power of the discharge is directly proportional to the electric field rotational frequency and voltage drop across the discharge medium and is inversely proportional to discharge medium gas pressure. In addition, using spectroscopical tools, specific electron impact excitations are identified within the generated plasma. The intensity of the identified emissions (corresponding to plasma species concentration) are investigated relative to gas pressure, voltage drop across the discharge medium, and electric field rotational frequency. The relative concentration of specific plasma species is directly or inversely proportional to gas pressure, voltage drop across discharge medium, and electric field rotational frequency depending on the plasma species being observed.

description: The diffusion coefficient of heavy quarks in the deconfined medium is examined in this research using a deep convolutional neural network (CNN) trained with data from relativistic heavy ion collisions involving heavy flavor hadrons. The CNN is trained using observables such as the nuclear modification factor $R_{AA}$ and the elliptic flow $v_2$ of non-prompt $J/ψ$ from B-hadron decay in different centralities, where B meson evolutions are calculated using the Langevin equation and the Instantaneous Coalescence Model. The CNN outputs the parameters characterizing the temperature and momentum dependence of the heavy quark diffusion coefficient. By inputting the experimental data of non-prompt $J/ψ$ $(R_{AA}, v_2)$ from various collision centralities into multiple channels of the well-trained network, we derive the values of the diffusion coefficient parameters. Additionally, We evaluate the uncertainty in determining the diffusion coefficient by taking into account the uncertainties present in the experimental data $(R_{AA}, v_2)$, which serve as inputs to the deep neural network.

Empowering Organizations in the Food Sector to Provide Potentially Unknown Parties Easy Access to Trusted Data. Discussion of a Web-based, Globally Applicable Solution Based on Well-established Standards and Technologies
Creators: name: Tröger, Ralph
Publisher: name: Proceedings in Food System Dynamics
Year: 2020

description: A number of the most relevant trends for the food sector require increased data sharing amongst different stakeholders. However, apart from established communication methods in the business-to-business (B2B) domain (e.g. bilateral exchange of EDI transactions or product master data synchronization), the level of standardization is low. There is no consistent, reliable and standardized entry point through which interested parties can easily discover and access data on products, shipments, parties, assets, or further business objects. Against this background, this paper aims at contributing to address this issue. To this end, it employs a number of prototypes and use cases to investigate the applicability of a new standard, GS1 Digital Link, in different areas of application. Thereby, it touches upon brand-authorized data (e.g. product information pages, list of retailers selling a given product), data for users of reusable transport items (e.g. temperature profiles provided by IoT-empowered trays), consumer-oriented data (e.g. nutrition information, related videos), master data pertaining to arbitrary business objects, service endpoints of EPCIS servers, and laboratory test data. The analysis reveals that the technical ecosystem GS1 Digital Link provides (especially normative specifications for resolvers, standardized link types, and consistent URI patterns) indeed represents an open, flexible, scalable, and future-oriented solution approach, which is superior to existing, proprietary solutions in various ways. In the course of the discussion, the paper also points to various open source projects intended to ease the adoption of this standard.

description: Quantum coherent control (1-3) is a powerful tool for steering the outcome of quantum processes towards a desired final state, by accurate manipulation of quantum interference between multiple pathways. Although coherent control techniques have found applications in many fields of science (4-9), the possibilities for spatial and high-resolution frequency control have remained limited. Here, we show that the use of counter-propagating broadband pulses enables the generation of fully controlled spatial excitation patterns. This spatial control approach also provides decoherence reduction, which allows the use of the high frequency resolution of an optical frequency comb (10,11). We exploit the counter-propagating geometry to perform spatially selective excitation of individual species in a multi-component gas mixture, as well as frequency determination of hyperfine constants of atomic rubidium with unprecedented accuracy. The combination of spectral and spatial coherent control adds a new dimension to coherent control with applications in e.g nonlinear spectroscopy, microscopy and high-precision frequency metrology.

description: A multicanonical formalism is introduced to describe statistical equilibrium of complex systems exhibiting a hierarchy of time and length scales, where the hierarchical structure is described as a set of nested "internal heat reservoirs" with fluctuating "temperatures." The probability distribution of states at small scales is written as an appropriate averaging of the large-scale distribution (the Boltzmann-Gibbs distribution) over these effective internal degrees of freedom. For a large class of systems the multicanonical distribution is given explicitly in terms of generalized hypergeometric functions. As a concrete example, it is shown that generalized hypergeometric distributions describe remarkably well the statistics of acceleration measurements in Lagrangian turbulence.

How Retailers’ Assortment Strategies and Food Prices Are Linked: Some Empirical Evidence for Germany
Creators: name: Herrmann, Roland

Publisher: name: Proceedings in Food System Dynamics
Year: 2020

description: The economics of grocery retailing is dominated by studies on pricing behaviour and the role of prices for the competitive position of retailers. Linkages to product policy have rarely been analyzed although the management literature indicates that an attractive assortment is one of the most important determinants of consumers’ store choices or even the most important one. Therefore, we raise the question how the retailers’ assortments and their price level are linked. After a literature review on the role of assortments and their influence on consumers and food prices, we analyze a large dataset for eight major German online retailers and their whole assortments of foods and beverages. It is investigated whether and how the assortments of online retailers affect their overall price level for foods and beverages. The econometric analysis reveals that various indicators of retailers’ product assortments drive the price level: (i) A deeper assortment of an online retailer raises his price level of foods and beverages significantly. (ii) The organization of the website and, thus, consumers’ transaction costs, matter too. (iii) There are strong retailer-specific fixed effects on the price level which may picture further assortment variables such as the breadth of the assortment or the private-label share.

description: We propose a novel approach to parameterize the equation of state for Scalar Field Dark Energy (SFDE) and use it to derive analytical solutions for various cosmological parameters. Using statistical MCMC with Bayesian techniques, we obtain constraint values for the model parameters and analyze three observational datasets. We find a quintessence-like behavior for Dark Energy (DE) with positive values for both model parameters $α$ and $β$. Our analysis of the $CC$+$BAO$+$SNe$ datasets reveals that the transition redshift and the current value of the deceleration parameter are $z_{tr}=0.73_{-0.01}^{+0.03}$ and $q_{0}=-0.44_{-0.02}^{+0.03}$, respectively. We also investigate the fluid flow of accretion SFDE around a Black Hole (BH) and analyze the nature of the BH's dynamical mass during accretion, taking into account Hawking radiation and BH evaporation. Our proposed model offers insight into the nature of DE in the Universe and the behavior of BHs during accretion.

Personality traits of German livestock farmers: Are there differences according to the production system?
Creators: name: Schröter, Iris
name: Mergenthaler, Marcus
Publisher: name: Proceedings in Food System Dynamics
Year: 2020

description: Decisions made by farmers can have large influences beyond the farm boundary because farmers are the first link in the food supply chain. For this reason, understanding their decision-making behaviour may be of interest to all stakeholders of food systems. Since there is considerable evidence that personality traits may affect decision-making behaviour, this paper investigates personality traits according to the HEXACO model of personality in a sample of 244 German livestock farmers. Our results indicate that livestock farmers differ in their personality from the general population, with farmers scoring higher on honesty-humility, conscientiousness and being more emotionally stable. Comparisons within the farmer sample show that organic livestock farmers score higher on Openness than conventional farmers. However, the results of a confirmatory factor analysis suggest that the German version of the short item scale used to measure the personality traits of the sample should be partially modified. Even though our results should therefore be understood rather as first indications and a basis for further research, they could help to better align support strategies, e.g. for more animal-friendly production, with the personality traits of farmers.

How fast do Jupiters grow? Signatures of the snowline and growth rate in the distribution of gas giant planets

description: We present here observational evidence that the snowline plays a significant role in the formation and evolution of gas giant planets. When considering the population of observed exoplanets, we find a boundary in mass-semimajor axis space that suggests planets are preferentially found beyond the snowline prior to undergoing gap-opening inward migration and associated gas accretion. This is consistent with theoretical models suggesting that sudden changes in opacity -- as would occur at the snowline -- can influence core migration. Furthermore, population synthesis modelling suggests that this boundary implies that gas giant planets accrete ~ 70 % of the inward flowing gas, allowing ~ 30$ % through to the inner disc. This is qualitatively consistent with observations of transition discs suggesting the presence of inner holes, despite there being ongoing gas accretion.

description: We propose Chunks and Tasks, a parallel programming model built on abstractions for both data and work. The application programmer specifies how data and work can be split into smaller pieces, chunks and tasks, respectively. The Chunks and Tasks library maps the chunks and tasks to physical resources. In this way we seek to combine user friendliness with high performance. An application programmer can express a parallel algorithm using a few simple building blocks, defining data and work objects and their relationships. No explicit communication calls are needed; the distribution of both work and data is handled by the Chunks and Tasks library. This makes efficient implementation of complex applications that require dynamic distribution of work and data easier. At the same time, Chunks and Tasks imposes restrictions on data access and task dependencies that facilitates the development of high performance parallel back ends. We discuss the fundamental abstractions underlying the programming model, as well as performance and fault resilience considerations. We also present a pilot C++ library implementation for clusters of multicore machines and demonstrate its performance for sparse blocked matrix-matrix multiplication.

Eleven of these inversion lines, the (J,K) = (6,2), (5,3), (7,4), (8,5), (7,6), (7,7), (9,7), (10,7), (9,9), (10,9), and (12,12) transitions, are classified as masers for the first time in outer space. All detected masers are related to highly excited inversion doublets. The (5,4) maser originates from an inversion doublet 340 K above the ground state, while the (12,12) transition, at 1450 K, is the most highly excited NH3 maser line so far known. Strong variability is seen not only in ortho- but also in para-NH3 transitions. Bright narrow emission features are observed, for the first time, in (mostly) ortho-ammonia transitions, at V ~ 45 km/s, well separated from the quasi-thermal emission near 60 km/s. These features were absent 25 years ago and show a velocity drift of about +0.2 km/s/yr. The component is likely related to the SiO maser source in W51-IRS2 and a possible scenario explaining the velocity drift is outlined. The 57 km/s component of the (9,6) maser line is found to be strongly linearly polarized. Maser emission in the (J,K) to (J+1,K) inversion doublets is strictly forbidden by selection rules for electric dipole transitions in the ground vibrational state. However, such pairs (and even triplets with (J+2,K)) are common toward W51-IRS2. Similarities in line widths and velocities indicate that such groups of maser lines arise from the same regions, which can be explained by pumping through vibrational excitation. The large number of NH3 maser lines in W51-IRS2 is most likely related to the exceptionally high kinetic temperature and NH3 column density of this young massive star forming region.

description: Within the effective Lagrangian framework, we explicitly evaluate the partition function of two-dimensional ideal ferromagnets up to three loops at low temperatures and in the presence of a weak external magnetic field. The low-temperature series for the free energy density, energy density, heat capacity, entropy density, as well as the magnetization are given and their range of validity is critically examined in view of the Mermin-Wagner theorem. The calculation involves the renormalization and numerical evaluation of a particular three-loop graph which is discussed in detail. Interestingly, in the low-temperature series for the two-dimensional ideal ferromagnet, the spin-wave interaction manifests itself in the form of logarithmic terms. In the free energy density the leading such term is of order $T^4 \ln T$ -- remarkably, in the case of the three-dimensional ideal ferromagnet no logarithmic terms arise in the low-temperature series. While the present study demonstrates that it is straightforward to consider effects up to three-loop order in the effective field theory framework, this precision seems to be far beyond the reach of microscopic methods such as modified spin-wave theory.

description: The present paper examines the attitudes and investment behavior of arable crop farmers in a comparative context with farmers that specialize in tree farming (fruit and nuts). The paper reveals that there exist significant differences on the investment behavior of the two groups. It also shows that various attitudes such as the pro-environmental stance, acceptance of EU identity and farming motive as well as farmers behavior regarding research and information engagement have a different impact on the investment behavior of the two groups as this is revealed by a series of correlation analyses. The results of the paper are expected to be very useful for guiding policy makers in drawing effective policies for mobilizing the two groups of farmers toward the improvement and modernization of their farms.

Search for contact interactions and large extra dimensions in dilepton events from pp collisions at sqrt(s) = 7 TeV with the ATLAS detector

description: A search for non-resonant new phenomena, originating from either contact interactions or large extra spatial dimensions, has been carried out using events with two isolated electrons or muons. These events, produced at the LHC in proton-proton collisions at sqrt(s) = 7 TeV, were recorded by the ATLAS detector. The data sample, collected throughout 2011, corresponds to an integrated luminosity of 4.9 and 5.0 fb-1 in the e+e- and mu+mu- channels, respectively. No significant deviations from the Standard Model expectation are observed. Using a Bayesian approach, 95% confidence limit lower limits ranging from 9.0 to 13.9 TeV are placed on the energy scale of llqq contact interactions in the left-left isoscalar model. Lower limits ranging from 2.4 to 3.9 TeV are also set on the string scale in large extra dimension models. After combination of these limits with results from a similar search in the diphoton channel, slightly more stringent limits are obtained.

Loss and Waste in the Australian Fresh Apple Value Chain

description: Apples are a significant and popular fruit among the Australian population, and in the case of fresh apples, the domestic market is relatively self-sustaining. Retail and consumer preferences are the driving force for quality standards for apples along the chain, with actors working to provide the best quality selection of produce. In order to meet these high standards, loss and waste occurs in the lower grades which are simply a by-product of first grade production. Globally, loss and waste of fresh produce is amongst the highest of all food groups and from the limited data available, apples appear to be no exception. While there is not accurate specific data regarding loss and waste data of fresh apples in the Australian value chain, reporting is increasing as is awareness of the broader issues of food loss and waste. Following along the value chain, there appear to be discrepancies in quantities of fresh apples available at the various stages, with these variations potentially reflective of loss and waste along the chain. Using best estimates from the literature, the total amount of fresh apples, conservatively, that is potentially diverted from the Australian fresh apple supply chain is around 163,000 tonnes which is about 41 per cent of total production at the farm level. What is also lacking from Australian market data and literature, other than robust primary loss and waste data, is the cost of food loss and waste, and the extent of the externalities that occur due to loss and waste along the value chain. Not only do negative externalities incur costs to the broader society, there are additional costs of intervention, and analysis is required to determine the feasibility and appropriateness of intervention strategies.

Food Waste Knowledge in Austria: A Consumer Perspective
Creators: name: Meixner, Oliver
Publisher: name: Proceedings in Food System Dynamics
Year: 2020

description: In times of increasing environmental awareness, the topic of food waste receives high attention from practitioners and scholars alike. In this study we analyze how well-informed Austrian consumers are regarding food waste and what factors might influence this knowledge. In a consumer survey (n = 470), we examined consumer food and food handling knowledge, cooking skills, place of living, personal ties to agriculture, engagement in initiatives against food waste, and their effect on food waste knowledge. To understand what effect social desirability might have on participants’ answers, we administered the survey both in an online and a face to face setting. Amongst others, our findings suggest a positive relationship between knowledge about food and food handling and knowledge about food waste prevention as well as a social desirability bias in reporting one’s own knowledge about food waste prevention. We could not find a statistically significant relationship between food and food handling knowledge, and food waste knowledge. Furthermore, we did not find evidence that a personal connection to agriculture or a rural place of living leads to a higher food waste knowledge. Finally, the unexpected influence of cooking skills is at least surprising to a certain extent. We conclude this study by outlining potential areas for future research as well as managerial implications.
