description: Food safety economists have raised numerous questions according to the emergence and the multiplication of safety quality management system within the food supply chain. However, few research deal with the voluntary implementation by firms of these systems (Segerson, 1999; Venturini, 2003; Noelke- Caswell, 2000). Our paper aims to develop a unified analytical framework of these research. We obtain three results. First, in a market model when the mandatory threat is strong, the voluntary adoption of safety measures is an equilibrium without need of the cost differential assumption (Segerson, 1999) nor of a reputation effect (Venturini, 2003). Second, when the mandatory threat is weak the reputation effect and the rule of liability could induce the voluntary adoption on different extent depending on the situation of safety contamination. Third, in a supply chain model we introduce a retailer and show that a well designed contract offered by the retailer induce upstream firms to voluntarily implement safety measures. Private incentives are thus very powerful and can be used as the sole mechanism to implement the efficient system.

description: Sterigmatospora Q.M. Wang & F.Y. Bai gen. nov. MycoBank MB828810.
 Etymology: the genus is named based on the morphology of the vegetative cells, which produce conidia on stalk-like conidiophores.
 This genus is proposed for the branch represented by strain CGMCC 2.5817, which formed a separate clade. Member of the Jianyuniaceae (Agaricostilbales). The genus is mainly circumscribed by the phylogenetic analysis of the seven genes dataset, in which it occurred as a separate branch within Jianyuniaceae (Fig. 4A).
Sexual reproduction not known. Colonies cream, butyrous. Budding cells present and blastoconidia produced on stalk-like conidiophores. Conidiophore single or multiple, usually cluster on cells. Pseudohyphae and hyphae not produced. Ballistoconidia not formed.
 Type species: Sterigmatospora layueensis Q.M. Wang, F.Y. Bai & A.H. Li.
 Note: Sterigmatospora and Pseudosterigmatospora can produce stalk-like conidiophores, the former usually produces cluster of conidiophores from one site on cells, the latter can form bifurcate or trifurcate conidophores. They are also distinguished by some physiological characteristics (Table S1.21), such as assimilation of raffinose and growth in vitamin-free medium.

description: Dynamical systems, for instance in model predictive control, often contain unknown parameters, which must be determined during system operation. Online or on-the-fly parameter identification methods are therefore necessary. The challenge of online methods is that one must continuously estimate parameters as experimental data becomes available. The existing techniques in the context of time-dependent partial differential equations exclude the case where the system depends nonlinearly on the parameters.Based on a model reference adaptive system approach, we present an online parameter identification method for nonlinear infinite-dimensional evolutionary system.

description: The paper analyses the trade relationships among EU- 15 members and some emerging partners : the NMS, Turkey and China. The EU enlargement to 10 countries has modified quite remarkably the features of agri-food trade in Europe. Some of the NMS, such as Poland, Hungary and the Check Republic, contribute to a large extent to the international agri-food trade and, since the beginning of the process of EU accession, have modified dramatically the exchanges with the EU- 15. More recently, other countries are facing new relationships with the EU : Turkey and China. Turkey is a large Mediterranean country and, as a candidate to the EU accession, enjoys a differential treatment in the agri- food trade relationships with the EU. China can be considered as a new international competitor, growing at faster pace after having joined the WTO and increasing its agri-food trade exchanges with the EU. The analysis will focus on the measurement of the similarity of agri-food exports of Italy and other EU-15 member States with the new partners to the EU- 15 market. It will be carried out with the support of three different indicators: the export structure similarity index (ES), the product similarity index (PSI) and the quality similarity index (QSI), using the Eurostat database with an eight "digit" merchandise disaggregation and with reference only to agri-food exchanges. It can be concluded that the similarity is quite low, especially if compared to that of the exports of the EU- 15 countries to the EU market. Moreover, looking at the level of quality of export products, it is highlighted how quality remains a crucial factor for Italian and European agri- food products to compete with external products. Keywords : International Competitiveness, Export Similarity, EU Agri- Food Market, EU Enlargement.

description: In this paper, we report the growth of NaxCoO2 thin films by pulsed-laser deposition (PLD). It is shown that the concentration of sodium is very sensitive to the substrate temperature and the target-substrate distance due to the evaporation of sodium during the deposition. alpha prime-phase Na0.75CoO2 and gamma- phase Na0.71CoO2 thin films can be obtained with different conditions. Correspondingly, the surface morphology of the films changes from flake-like to particle-like. The temperature dependence of resistivity for the films prepared with the optimal condition shows metallic behavior, consistent with the data of NaxCoO2 single crystals. This work demonstrates that PLD is a promising technique to get high quality NaxCoO2 thin films.

description: The aim of this paper is to analyse the various factors fuelling demand for Food- Away - From- Home (FAFH) in Ireland. The two largest components of this industry, the quick- service sector (fast food and takeaway) and the full- service sector (hotel and restaurant meals), are analysed using the most recently available Household Budget Survey data for Ireland. The results from a Box- Cox double hurdle model indicate that different variables affect expenditure in the different sectors in different ways. Income has a greater effect on full- service expenditure than on quick- service. Similarly households that are healthconscious indicate a greater preference for full- service meals while households with higher time values indicate a greater preference for quick- service. Households of a higher social class and those with higher education levels also appear to favour full- service expenditure. In addition, younger, urbanised households favour quick- service meal options. The results emphasise the merits of adopting a disaggregated approach to analysing foodservice expenditure patterns.

description: We use the 3+1 formalism of numerical relativity to investigate the robustness of Starobinsky and Higgs inflation to inhomogeneous initial conditions, in the form of either field gradient or kinetic energy density. Sub-Hubble and Hubble-sized fluctuations generically lead to inflation after an oscillatory phase between gradient and kinetic energies. Hubble-sized inhomogeneities also produce contracting regions that may end up forming primordial black holes, subsequently diluted by inflation. We analyse the dynamics of the preinflation era and the generation of vector and tensor fluctuations. Our analysis further supports the robustness of inflation to any size of inhomogeneity, in the field, velocity or equation of state. At large field values, the preinflation dynamics only marginally depends on the field potential and it is expected that such behaviour is universal and applies to any inflation potential of plateau-type, favoured by CMB observations after Planck.

description: Functional Food emerged as a constant segment in the European food market and offer potential for product innovations which make them attractive for the food industry in nearly stagnating markets. Target group research is one key factor for successful innovative food products. The aim of this project was to develop and test a Functional Food related consumer segmentation model. For this purpose a survey was conducted in Germany, the United Kingdom, Poland and Spain with a total of 590 respondents. Factor analysis revealed consumers' motivation to buy or to refuse Functional Food. Motives, consumers' knowledge about Functional Food, their trust towards diverse actors in the context of nutrition and their purchase pattern were used in a cluster analysis and resulted in eight consumer segments. These groups differ significantly regarding sociodemographic characteristics. A conjoint study examined consumers' preferences towards a new type of orange juice enriched with functional ingredients recombined with different health claims. Aggregated preferences for single consumer segments provide indications for target group specific product development. Cross- country comparison of consumer segments showed distinct shifts of segments' distribution in single countries. This might be considered for companies' marketing approaches or the European commission's health and consumer protection policy.

description: We use the IllustrisTNG100 hydrodynamical simulation to study the dependence of the galaxy two-point correlation function on a broad range of secondary subhalo and galactic properties. We construct galaxy mock catalogues adopting a standard sub-halo abundance matching scheme coupled with a secondary assignment between galaxy colour or specific star formation rate and the following subhalo properties: starvation redshift z$_{\rm starve}$, concentration at infall, overdensity $δ_R^{\rm env}$, tidal anisotropy $α_R$, and tidal overdensity $δ_R$. The last two quantities allow us to fully characterise the tidal field of our subhaloes, acting as mediators between their internal and large-scale properties. The resulting mock catalogues overall return good agreement with the IllustrisTNG100 measurements. The accuracy of each model strongly depends on the correlation between the secondary galaxy and subhalo properties employed. Among all the subhalo proxies tested, we find that z$_{\rm starve}$ and $c_{\rm infall}$ are the ones that best trace the large-scale structure, producing robust clustering predictions for different samples of red/blue and quenched/star-forming galaxies.

description: In this paper we focus on nonparametric estimators in inverse problems for Poisson processes involving the use of wavelet decompositions. Adopting an adaptive wavelet Galerkin discretization, we find that our method combines the well-known theoretical advantages of wavelet--vaguelette decompositions for inverse problems in terms of optimally adapting to the unknown smoothness of the solution, together with the remarkably simple closed-form expressions of Galerkin inversion methods. Adapting the results of Barron and Sheu [Ann. Statist. 19 (1991) 1347--1369] to the context of log-intensity functions approximated by wavelet series with the use of the Kullback--Leibler distance between two point processes, we also present an asymptotic analysis of convergence rates that justifies our approach. In order to shed some light on the theoretical results obtained and to examine the accuracy of our estimates in finite samples, we illustrate our method by the analysis of some simulated examples.

description: Many more consumer s have tried at least once organic food, but despite higher consumer awareness, they still show a great concern about food quality and safety. Recent research showed that there is still little knowledge of how organic products are produced and processed and which characteristics are fundamental for the consumer with regard to quality and safety. In this scenario, primary producers, processors and other stakeholders in the organic supply- chain have the difficult task of understanding consumers' complex and sometimes contradictory wishes with regard to organic food. The aim of this study is to examine food quality and safety issues related to buying organic products. To provide better insight on the safety and quality issues in a cross - cultural setting, the linkages among consumer's personal values - as final expression of consumer product knowledge - are analysed, by means of laddering data on 8 EU countries.

Chiaroscuro

description: Η φωτογραφία στον δρόμο έχει για εμένα δυο στοιχεία, την περιπλάνηση από την μια και την σύνθεση της εικόνας μέσα από το φως από την άλλη. Στην εργασία αυτή προσπάθησα με δικές μου εξορμήσεις στον δρόμο να προσεγγίσω το θέμα σαν ένας σύγχρονος “Flâneur”. Με τον όρο “Flâneur” από τα Γαλλικά, όπου ο Flâneur μέσα από τις εξορμήσεις του προσπαθούσε να ανακαλύψει ξανά την πόλη όπου οι ίδιοι οι κάτοικοί της προσπερνούσαν. Μέσα από τις περιπλανήσεις αυτές προσπαθούσε να αντλήσει από τον κόσμο τον ρομαντισμό και την καλλιτεχνική οπτική που εξαφανίστηκε μέσα στους αστικούς δρόμους της κάθε πόλης. Όπως είχε πει και ο Don McCullin για τον Henri Cartie-Bresson “κρατάει αποστάσεις κάπως σαν να είναι φάντασμα που περπατάει ανάμεσα στους ανθρώπους στον δρόμο”1. Σαν τον άνθρωπο του πλήθους του Edgar Allan Poe έτσι και εγώ περπατούσα χαμένος μέσα στον κόσμο με την κάμερα περιμένοντας και αναζητώντας την στιγμή. Μέσα από τις εικόνες, μου αρέσει να δίνω ένα χαρακτήρα που οι απλές καθημερινές snapshots φωτογραφίες δεν μπορούν να αποδώσουν. Έτσι ανατρέχοντας στην ζωγραφική του Καραβάτζιο και την τεχνική του Chiaroscuro μπόρεσα να δώσω το δραματικό στοιχείο το οποίο μπορεί κάποιος να δει κάθε μέρα στους δρόμους μιας πόλης. Τα έντονα στοιχεία της σκιάς και το παιχνίδι του φωτός, δημιουργούν έναν καμβά τον οποίο μπορεί κάθε άνθρωπος να δει αν μπορέσει να κοντοσταθεί για λίγο. Έτσι και ο φωτογράφος με συνοδοιπόρο την κάμερα ξεκινά χωρίς προορισμό και χωρίς σίγουρο αποτέλεσμα Όπως ο Flâneur κινείται μέσα στον κόσμο, αντλώντας από αυτόν πολλά στοιχεία, με τον ίδιο τρόπο και ο φωτογράφος στην φωτογράφιση δρόμου μπορεί να αντλήσει έμπνευση να αναδείξει την πόλη μέσα από τις εικόνες του. Αυτό τουλάχιστον προσπάθησα να κάνω εγώ. 1 (Bright, 2012)

description: Motivated by the pair-density-wave (PDW) state found in the one-dimensional Kondo-Heisenberg chain, we report on a determinant quantum Monte Carlo DQMC study of pair-fields for a two-dimensional half-filled Hubbard layer coupled to an itinerant, non-interacting layer with one electron per site. In a specific range of interlayer hopping, the pairing vertex associated with PDW order becomes more attractive than that for uniform d-wave pairing, although both remain subdominant to the leading antiferromagnetic correlations at half-filling. Our result sheds light on where one potentially may find a PDW state in such a model.

description: Given the heterogeneity of European consumers it is not unsurprising that they have different perceptions and expectations regarding (but also understanding thereof) 'traceability'. A large number of individuals may not even have a memory anchor for the concept. Consumers may also perceive traceability differently among different product types. The present study is based upon focus groups analysis of 12 countries across Europe. It presents an explanation of traceability's understanding by European consumers. It also presents consumer's expectations towards traceability and its differences according to different product types.

To determine the Hawking radiation in the tunneling formalism we apply the Hamilton-Jacobi method by using the Wentzel-Kramers-Brillouin (WKB) approach. In the present study we have obtained logarithmic corrections to entropy due to the effect of noncommutativity and GUP. We also address the issue concerning stability of the non-commutative BTZ black hole by investigating its modified specific heat capacity.

Then the one-gluon-exchange interaction is perturbatively incorporated, leading to their mass spectral equations. The analytic forms of wave functions obtained from these equations are then used for calculation of leptonic decay constants of ground and excited states of $1^{++}$, and $1^{+-}$ as a test of these wave functions and the over all framework.

MICHIGAN RURAL HOSPITALS: CHANGES IN SPECIALIZED AND OUTPATIENT SERVICES BETWEEN 1980 AND 1984

description: This study aims to determine the extent to which Michigan rural hospitals decreased the total level of inpatient acute care services and changed the levels of various specialized and outpatient services as well as associated ancillary inputs during the period form 1980 to 1984. It is expected that many of these services either increased over this period or remained stable since many hospitals may have decided to recoup lost revenues from inpatient acute care and/or to prevent additional revenue losses. In any event, many changes in these services are expected to be a response to challenges of financial survival. The specialized and outpatient services in this study exclude inpatient acute care services. Specialized services are defined to comprise the major inpatient services in long-term care. Outpatient services comprise all major services provided on an outpatient basis. Ancillary inputs support, or might support, specialized and/or outpatient care. Note that important health professionals, such as allopathic physicians, are considered to be ancillary inputs. The variables that comprise or support specialized and outpatient services and the procedures to select them will be identified later. Hospital size, rural location, and ownership type (private or county) may be important factors associated with changes in rural hospitals (Grim, 1986; personal conversation with David Seamon and Laura Redoutey, Michigan Hospital Association (MHA, 3/15/87). This study aims to identify which of these associated factors help explain the extent of change in the variables representing specialized and outpatient services and associated ancillary inputs.

description: The primary objective of this paper is the consideration of the hypothesis that cash cropping has a negative impact on food consumption. An adequate consideration of this first hypothesis leads the analyst to scrutinize the diametrically opposing viewpoint as well. This second viewpoint is based on the conviction that nutritional problems will be overcome within the general process of economic development and that market specialization and integration are essential factors in that development process. The establishment of these two extreme hypotheses, these two "strawmen," will provide a framework within which a number of other objectives can be considered. In the order in which they are treated, they are: (1) The clarification of the "role" of nutrition in economic development; (2) The identification and evaluation of the broad range of factors beyond market integration which influence nutritional status; (3) The identification of the mechanisms by which the spread of cash crops affects food consumption and an analysis of the empirical record in this area; and (4) The examination at the household level of the relationship between food consumption goals and other family goals.

description: This work presents an algorithm for calculating high temperature series expansions (HTSE) of Heisenberg spin models with spin $S=1/2$ in the thermodynamic limit. This algorithm accounts for the presence of a magnetic field. The paper begins with a comprehensive introduction to HTSE and then focuses on identifying the bottlenecks that limit the computation of higher order coefficients. HTSE calculations involve two key steps: graph enumeration on the lattice and trace calculations for each graph. The introduction of a non-zero magnetic field adds complexity to the expansion because previously irrelevant graphs must now be considered: bridged graphs. We present an efficient method to deduce the contribution of these graphs from the contribution of sub-graphs, that drastically reduces the time of calculation for the last order coefficient (in practice increasing by one the order of the series at almost no cost). Previous articles of the authors have utilized HTSE calculations based on this algorithm, but without providing detailed explanations. The complete algorithm is publicly available, as well as the series on many lattice and for various interactions.

description: This study examines trends in total and per capita food crop production, marketing and prices in Rwanda during the period 1970-1991. It gives special emphasis to dry beans. This study is also concerned with gaining more insights into rural household level dry bean transactions, and gaining a better understanding of the relative importance of rural bean imports through informal cross-border trade with Rwanda's neighboring countries. More specifically, the intent is to provide potential users and Rwandan policy makers with information on household dry bean transaction trends and other key market behavior indicators such as volume of bean sales, purchases, rural consumption and imports. Empirical analysis, using a national informal imports identity approach and data from the 1990 ENRD, leads to a major conclusion that Rwanda is increasingly a net importer of dry beans. It is also found that a large and growing majority (84%) of rural households are net purchasers of beans. Results of the analysis show also a decline in bean and overall calorie production on both per capita and total basis (from 8 major food crops studied) among households in the net buyer categories. Analysis undertaken to determine whether for a given household net sales position for one commodity are correlated with the net sales volume of other commodities shows relatively weak relationships at the national level, thus revealing some degree of specialization in sales. When analysis is conducted by selecting only households who are net sellers of beans, sweet potatoes or bananas and on agroclimatical zones basis, more insights are gained on the degree of specialization in sales at the household level. Bean production (coupled with overall food crop output) instability has led to year-to-year and monthly bean price fluctuations. This analysis tries to identify some of the factors responsible for such deviations from the typical seasonal pattern. Government officials and private sector managers involved in the bean subsector are under increasing pressure to adjust their policy decisions under different bean supply cenarios. This study provides potentially useful information about such issues and suggests possible public and private actions to be taken that could better facilitate the process of regional integration of dry bean markets in Rwanda and neighboring countries of Zaire, Uganda and Burundi.

description: We introduce $\sf{CosmoBit}$, a module within the open-source $\sf{GAMBIT}$ software framework for exploring connections between cosmology and particle physics with joint global fits. $\sf{CosmoBit}$ provides a flexible framework for studying various scenarios beyond $Λ$CDM, such as models of inflation, modifications of the effective number of relativistic degrees of freedom, exotic energy injection from annihilating or decaying dark matter, and variations of the properties of elementary particles such as neutrino masses and the lifetime of the neutron. Many observables and likelihoods in $\sf{CosmoBit}$ are computed via interfaces to $\sf{AlterBBN}$, $\sf{CLASS}$, $\sf{DarkAges}$, $\sf{MontePython}$, $\sf{MultiModeCode}$, and $\sf{plc}$. This makes it possible to apply a wide range of constraints from large-scale structure, Type Ia supernovae, Big Bang Nucleosynthesis and the cosmic microwave background. Parameter scans can be performed using the many different statistical sampling algorithms available within the $\sf{GAMBIT}$ framework, and results can be combined with calculations from other $\sf{GAMBIT}$ modules focused on particle physics and dark matter. We include extensive validation plots and a first application to scenarios with non-standard relativistic degrees of freedom and neutrino temperature, showing that the corresponding constraint on the sum of neutrino masses is much weaker than in the standard scenario.

Microbial utilization of dissolved organic matter leached from riparian tree species of different serial stages

description: Dissolved organic matter (DOM) leached from five coastal forest litterfall types. Red alder, vine maple, western red cedar, western hemlock and Douglas-fir, were studied to assess their DOM chemistry and relative ability to support growth of heterotrophic, stream bacteria. Bacterial growth was measured using [ H] leucine incorporated into protein over 24 hours of exposure to nutrient-amended leachates. Bacterial growth was greatest in deciduous and western red cedar leachates when controlling for dissolved organic carbon (DOC) concentration. The bacterial growth rates on most leachate types were greatest after one hour, then declined in a negative exponential pattern. The DOM less than 10 000 nmw supported lower bacterial growth rates than DOM from whole leachates on a per mg DOC basis. The DOM carbon to nitrogen atomic ratio was the best predictor of bacterial growth (r² = 0.84). A seven day leaching experiment revealed that DOC release from western hemlock needles increased linearly while the majority of red alder and western red cedar DOC was released after one or two days, respectively. The patterns recorded in stream DOM quantity and quality indicated that riparian vegetation type may directly influence stream DOM chemistry. Through successional changes in tree species composition, riparian forests can influence the stream microbial productivity based on the changes in dissolved organic matter.

description: Novel methods to reconstruct the slant depth of the maximum of the longitudinal profile (\Xmax) of high-energy showers initiated by gamma-rays as well as their energy ($E_0$) are presented. The methods were developed for gamma rays with energies ranging from a few hundred GeV to $\sim 10$ TeV. An estimator of \Xmax is obtained, event-by-event, from its correlation with the distribution of the arrival time of the particles at the ground, or the signal at the ground for lower energies. An estimator of $E_0$ is obtained, event-by-event, using a parametrization that has as inputs the total measured energy at the ground, the amount of energy contained in a region near to the shower core and the estimated \Xmax. Resolutions about $40 \, (20)\,{\rm g/cm^2}$ and about $30 \, (20)\%$ for, respectively, \Xmax and $E_0$ at $1 \, (10) \ \rm{TeV}$ energies are obtained, considering vertical showers. The obtained results are auspicious and can lead to the opening of new physics avenues for large wide field-of-view gamma-ray observatories. The dependence of the resolutions with experimental conditions is discussed.

description: Pesticide contamination of groundwater has been linked to intensive agricultural activity. Several federal legislations have been applied to protect groundwater quality from on-farm pesticide contamination, but results have not been notable. The environmental protection agency has mandated that states develop management plans based on area-specific differences in groundwater use, value, and vulnerability. The Michigan Department of Agriculture (MDA) has been structuring its programs based on a combination of aquifer sensitivity and groundwater impact potential; and attempting to estimate aquifer sensitivity based on soil type and sub-surface geology. This paper is to define the method to estimated total mass of "likely to leach" pesticides applied in each county in Michigan. Survey data collected from Michigan Agricultural Statistics Service, National Agricultural Statistics Service, Michigan County Food and Agricultural Development Statistics, and pesticide-use-site codes were used to identify pesticide use site type and distribution. The pesticide use activities and practices which may contaminate groundwater were also identified. Seventy-two site types have been identified. Two types of matrices describing the magnitude of each site type in a county and the available pesticide use information associated with each site type were developed. An estimate of the total mass of likely to leach pesticides applied in each county were computed by combining these matrices, and the missing information was also identified. The possible methodology of completing the prototype matrices and the potential uses of matrix was discussed.

description: We prove that if $M$ is a CW-complex and $M^1$ is its 1-skeleton then the crossed module $Π_2(M,M^1)$ depends only on the homotopy type of $M$ as a space, up to free products, in the category of crossed modules, with $Π_2(D^2,S^1)$. From this it follows that, if $G$ is a finite crossed module and $M$ is finite, then the number of crossed module morphisms $Π_2(M,M^1) \to G$ can be re-scaled to a homotopy invariant $I_G(M)$, depending only on the homotopy 2-type of $M$. We describe an algorithm for calculating $π_2(M,M^{(1)})$ as a crossed module over $π_1(M^{(1)})$, in the case when $M$ is the complement of a knotted surface $Σ$ in $S^4$ and $M^{(1)}$ is the handlebody made from the 0- and 1-handles of a handle decomposition of $M$. Here $Σ$ is presented by a knot with bands. This in particular gives us a geometric method for calculating the algebraic 2-type of the complement of a knotted surface from a hyperbolic splitting of it. We prove in addition that the invariant $I_G$ yields a non-trivial invariant of knotted surfaces in $S^4$ with good properties with regards to explicit calculations.

description: This paper establishes the basis of the quaternionic differential geometry ($\mathbbm H$DG) initiated in a previous article. The usual concepts of curves and surfaces are generalized to quaternionic constraints, as well as the curvature and torsion concepts, differential forms, directional derivatives and the structural equations. The analogy between the quaternionic and the real geometries is obtained using a matrix representation of quaternions. The results evidences the quaternionic formalism as a suitable language to differential geometry that can be useful in various directions of future investigation.
