description: Die Vermarktung von ökologischen Lebensmitteln ist in Deutschland an die Einhaltung der entsprechenden europäischen Rahmenvorschrift geknüpft. Bis Ende 2008 war dies die Verordnung (EWG) Nr. 2092/91, deren Einhaltung durch die Öko-Lebensmittelwirtschaft in Deutschland von privaten Kontrollstellen überprüft wird. Die privaten Kontrollstellen melden im Rahmen der gesetzlich vorgeschriebenen Überwachung Daten zu Kontroll- und Sanktionshäufigkeiten der Unternehmen an die Bundesanstalt für Landwirtschaft und Ernährung. Dieser Beitrag analysiert die entsprechenden Daten des Jahres 2006. Dabei werden für die neun größten deutschen Öko-Kontrollstellen einerseits die Art der durchgeführten Kontrollen, deren absolute und relative Häufigkeit und die Kontrollergebnisse (insbesondere Verstöße und schwere Sanktionen) betrachtet. Zum Anderen wird der Frage nachgegangen, ob bei der relativen Sanktionshäufigkeit der kontrollierten Unternehmen Unterschiede zwischen verschiedenen Öko-Kontrollstellen bestehen. Darauf aufbauend werden zwei grundlegende Erklärungsansätze für die vorgefundenen signifikant unterschiedlichen Sanktionshäufigkeiten diskutiert. Schließlich werden die Anforderungen an Daten zur näheren Analyse dieser Ansätze beschrieben.

description: We discuss condensations of closed string tachyons localized in compact spaces. Time evolution of an on-shell condensation is naturally related to the worldsheet RG flow. Some explicit tachyonic compactifications of Type II string theory is considered, and some of them are shown to decay into supersymmetric theories known as the little string theories.

The influence of additives on microstructure evolution of electrochemically deposited copper films
Creators: name: Gao, Jie
Publisher: name: University of British Columbia
Year: 2009

description: This thesis presents an investigation of the effects of additives on kinetics of deposition and microstructure evolution of Cu films, which were electrochemically deposited (ECD) on Au substrates. The rate of bulk Cu deposition was quantified with cyclic voltammetry. The self-annealing of the as-deposited Cu films was recorded at room temperature with resistivity measurements. Furthermore, the grain size evolution during self-annealing was characterized by X-ray diffraction. The challenges associated with these measurements such as reproducibility tests, the effects of substrate quality, and the aging of chemicals is discussed in detail. A systematic error of resistivity measurements is reduced to 3% by correcting the resistivities value. Considering the sensitivity in the measurement of initial absolute resistivity, it is suggested to use the normalized resistivity for presenting the results. XRD technique is a good way for estimating the microstructure evolution during self-annealing. However, the use of resistivity techniques is recommended to investigate self-annealing kinetics. The additives, PEG and SPS play an important role in influencing the deposition rate and self-annealing rate, whereas, the effect in JGB also cannot be neglected especially its influence during underpotential deposition (UPD) stage and on the rate of self-annealing. A suitable selection of the type and the concentration in additives will be the key to control the kinetics of deposition and self-annealing in order to match the requirements of Cu interconnects.

description: The cooperative movement in Poland has a long but difficult history. The socialistic regime introduced a command and control system into cooperatives which was destructive to their self-governing functions and eventually led to a lack of member involvement. There was a mass neglecting and abandonment after the transformation in particular of rural cooperatives. Nonetheless, in the early 1990s the first farmers’ cooperative marketing organizations, called agricultural producer groups, appeared on the market. They are bottom-up, voluntary organizations whose main purpose is to jointly sell their members’ output Although producer groups functions similarly to marketing cooperatives, farmers establishing producer groups have been choosing other legal forms than cooperatives. In the paper we investigate why the new forms of governance of cooperative arrangements are chosen and what are the implication of these choices for the success of the groups on the market. We discuss the impact of invested capital, the impact of advisors, and the impact of institutional environment on this choice. The empirical data was collected on 62 producer groups functioning in one province of Poland.

description: Quantifying the influence of microscopic details on the dynamics of development of the overall structure of a filamentous network is important in a number of biologically relevant contexts, but it is not obvious what order parameters can be used to adequately describe this complex process. In this paper, we investigated the role of multivalent actin-binding proteins (ABPs) in reorganizing actin filaments into higher-order complex networks via a computer model of semiflexible filaments. We characterize the importance of local connectivity among actin filaments as well as the global features of actomyosin networks. We first map the networks into local graph representations and then, using principles from network-theory order parameters, combine properties from these representations to gain insight on the heterogeneous morphologies of actomyosin networks at a global level. We find that ABPs with a valency greater than two promote filament bundles and large filament clusters to a much greater extent than bivalent multilinkers. We also show that active myosin-like motor proteins promote the formation of dendritic branches from a stalk of actin bundles. Our work motivates future studies to embrace network theory as a tool to characterize complex morphologies of actomyosin detected by experiments, leading to a quantitative understanding of the role of ABPs in manipulating the self-assembly of actin filaments into unique architectures that underlie the structural scaffold of a cell relating to its mobility and shape.

description: We report measurements of electric potentials at the surface of a spherical container of liquid sodium in which a magnetized inner core is differentially rotating. The azimuthal angular velocities inferred from these potentials reveal a strong super-rotation of the liquid sodium in the equatorial region, for small differential rotation. Super-rotation was observed in numerical simulations by Dormy et al. [1]. We find that the latitudinal variation of the electric potentials in our experiments differs markedly from the predictions of a similar numerical model, suggesting that some of the assumptions used in the model - steadiness, equatorial symmetry, and linear treatment for the evolution of both the magnetic and velocity fields - are violated in the experiments. In addition, radial velocity measurements, using ultrasonic Doppler velocimetry, provide evidence of oscillatory motion near the outer sphere at low latitude: it is viewed as the signature of an instability of the super-rotating region.

description: Measurements of a permanent neutron electric dipole moment (EDM) potentially probe Beyond-the-Standard Model (BSM) sources of CP-violation. At low energy the CP-violating BSM interactions are parametrized by flavor-conserving CP-violating operators of dimension higher than four. QCD calculations of the nucleon matrix elements of these operators are required to fully reconstruct the sources and magnitudes of the different CP-violating contributions to the nucleon EDM. Herein we study the quark-chromo electric dipole moment (qCEDM) operator and the three-gluon Weinberg operator. The non-perturbative determination, using lattice QCD, of the nucleon matrix elements of these CP-violating operators is hampered by their short-distance behavior. Under renormalization these operators mix with lower dimensional operators, which induces power divergences in the lattice spacing, as the continuum limit is approached. We study the short-distance behavior of the qCEDM and the Weinberg operators using the gradient flow. We perform a short flow time expansion and determine, in perturbation theory, the expansion coefficients of the linearly-divergent terms stemming from the mixing with the pseudoscalar density and the topological charge, confirming the expectations of the operator product expansion. We introduce a new method to perform calculations at non-zero flow-time for arbitrary values of the external momenta. This method allows us to work in four dimensions for most of the calculations described in this paper, avoiding the complications associated with defining $γ_5$ in generic d dimensions. We show that leading contributions in the external momenta can be reproduced by defining $γ_5$ using the 't Hooft-Veltman-Breitenlohner-Maison scheme.

An experimental investigation of the early dynamic impact behaviour of textile armour systems : decoupling material from system response
Creators: name: Cepuš, Elvis
Publisher: name: University of British Columbia
Year: 2009

description: This work focuses on the early impact response of textile armour systems. A relatively new data acquisition system, the Enhanced Laser Velocity Sensor (ELVS), was refined and used to generate a large database of results for a 5.57 mm diameter, 3 gram, non-deforrning projectile impacting single-ply configurations of Ballistic Nylon, two weaves of Kevlar 129, and Zylon (PBO) over a range of velocities from 61 m/s to 248 m/s. In addition, one Kevlar 129 material was tested i n configurations of 2, 3, 4, 8 and 16 plies over a range of strike velocities from 90 m/s to 481 m/s. ELVS results consisted of high-resolution timehistories of displacement, velocity and energy for each system tested. The strain wave velocity and ballistic performance of each system was also determined. Results taken from during the impact event were analysed up to just prior to the strain-wave rebounding from the boundary and returning to the impact point - effectively removing boundary influences. Regardless of system type, a constant rate of energy absorption witiiin the pre-rebound timeframe was found to exist, which scales with the strike velocity to approximately the 8/3-power. Well-established single fibre theory was modified and applied to woven materials. It was assumed that three primary energy absorption mechanisms exist; elastic strain, in-plane kinetic and out-of-plane kinetic. This simple model yields the experimentally observed 8/3 exponent and parametrically predicts the difference between the different single-ply material systems, but underpredicts the observed behaviour by a factor of 2 and cannot address the performance reduction with increasing ply count. This combined experimental and analytical work confirms the long-held assumption that single fibre wave physics is applicable to multi-ply woven systems. More significantly, for the first time, it decouples material response from overall system response and provides the experimental tools and methodology required to analyse textile armour systems in a scientific manner.

description: Der Einfluss der Entwicklungen auf verschiedenen Agrarmärkten auf den deutschen Rapsmarkt wird im vorliegenden Beitrag anhand von multivariaten Zeitreihenmodellen für die Produktpreise untersucht. Da sich in Hochpreisphasen die Preisanpassungsprozesse möglicherweise im Vergleich zu Phasen niedriger Preise ändern, wird auf ein nichtlineares Vektor-Fehlerkorrektur-Modell (VFKM) zurückgegriffen, das regimeabhängige Anpassungen zulässt. Die Spezifikation des Modells als Markovsprung-VFKM (MS-VFKM) erweist sich hier als vorteilhaft, da es keiner a priori Regimespezifizierung und -abgrenzung bedarf. Die Analyse zeigt, dass in den Jahren 2007/08 signifikante Änderungen in den Anpassungsprozessen der Rapspreise im Verhältnis zu anderen Agrargütern auftraten, wobei sowohl Weizen- als auch Sojapreise einen signifikanten Einfluss ausübten. Als entscheidend für das Ausmaß und die Nachhaltigkeit des Rapspreisanstiegs kann hingegen der Abbau von Abweichungen vom langfristigen Gleichgewicht zwischen Rapsöl- und Rapsschrotpreis determiniert werden.
Generating cosmological perturbations with mass variations

description: We study the possibility that large scale cosmological perturbations have been generated during the domination and decay of a massive particle species whose mass depends on the expectation value of a light scalar field. We discuss the constraints that must be imposed on the field in order to remain light and on the annihilation cross section and decay rate of the massive particles in order for the mechanism to be efficient. We compute the resulting curvature perturbations after the mass domination, recovering the results of Dvali, Gruzinov, and Zaldarriaga in the limit of total domination. By comparing the amplitude of perturbations generated by the mass domination to those originally present from inflation, we conclude that this mechanism can be the primary source of perturbations only if inflation does not rely on slow-roll conditions.

description: Cosmic voids provide a powerful probe of the origin and evolution of structures in the Universe because their dynamics can remain near-linear to the present day. As a result they have the potential to connect large scale structure at late times to early-Universe physics. Existing "watershed"-based algorithms, however, define voids in terms of their morphological properties at low redshift. The degree to which the resulting regions exhibit linear dynamics is consequently uncertain, and there is no direct connection to their evolution from the initial density field. A recent void definition addresses these issues by considering "anti-halos". This approach consists of inverting the initial conditions of an $N$-body simulation to swap overdensities and underdensities. After evolving the pair of initial conditions, anti-halos are defined by the particles within the inverted simulation that are inside halos in the original (uninverted) simulation. In this work, we quantify the degree of non-linearity of both anti-halos and watershed voids using the Zel'dovich approximation. We find that non-linearities are introduced by voids with radii less than $5\,\mathrm{Mpc}\,h^{-1}$, and that both anti-halos and watershed voids can be made into highly linear sets by removing these voids.

description: Evolutionary Aesthetics emerges today as a young and lively field of studies whose main aim is to rethink the traditional questions of philosophical Aesthetics in the light of biological theories, in particular in the light of Darwin's evolutionary theory by means of natural selection. The aim of this issue is to introduce Evolutionary Aesthetics into the Italian philosophical debate. Contributions collected cover almost entirely the lively, multifaceted spectrum of the discipline: 1) the high-debated question of the adaptive value of aesthetic sense, artistic practices and art fruition (Stephen Davies, Zach Norwood, Joseph Carroll); 2) the evolutionary explanation of human sexual preferences and production of artefacts (Hannes Rusch & Eckart Voland); 3) the possibility for a Darwinian non-reductionist definition of art as a culturally differentiated behavior (Kathryn Coe; Nancy E. Aiken; Roberta Dreon); 4) a comparative analysis of aesthetic experience from a cognitive viewpoint (Gianluca Consoli) and from a morphological one (Salvatore Tedesco); 5) the influence of Darwinian perspective beyond the English boundaries, with particular reference to the Italian scientific community in the Nineteenth century (Elena Canadelli) and to the tradition of Gestaltpsychologie (Michele Gardini); 6) a naturalistic approach to aesthetic experience and medial experience (Antonino Pennisi & Francesco Parisi).

description: High-Level Synthesis enables the rapid prototyping of hardware accelerators, by combining a high-level description of the functional behavior of a kernel with a set of micro-architecture optimizations as inputs. Such optimizations can be described by inserting pragmas e.g. pipelining and replication of units, or even higher level transformations for HLS such as automatic data caching using the AMD/Xilinx Merlin compiler. Selecting the best combination of pragmas, even within a restricted set, remains particularly challenging and the typical state-of-practice uses design-space exploration to navigate this space. But due to the highly irregular performance distribution of pragma configurations, typical DSE approaches are either extremely time consuming, or operating on a severely restricted search space. This work proposes a framework to automatically insert HLS pragmas in regular loop-based programs, supporting pipelining, unit replication, and data caching. We develop an analytical performance and resource model as a function of the input program properties and pragmas inserted, using non-linear constraints and objectives. We prove this model provides a lower bound on the actual performance after HLS. We then encode this model as a Non-Linear Program, by making the pragma configuration unknowns of the system, which is computed optimally by solving this NLP. This approach can also be used during DSE, to quickly prune points with a (possibly partial) pragma configuration, driven by lower bounds on achievable latency. We extensively evaluate our end-to-end, fully implemented system, showing it can effectively manipulate spaces of billions of designs in seconds to minutes for the kernels evaluated.

description: A study was conducted during 1994-1995 amongst policy makers, government officials, retailers and millers in Lesotho to review the maize marketing system and procedures for setting maize prices at producer, mill-gate and consumer levels. Set prices distort price signals which influence decisions to allocate and distribute resources to provide goods and services for markets. Lesotho is a net importer of maize grain, the major staple, implying that maize pricing and marketing policy affect food security. Results indicate flexible informal marketing channels, fixed formal marketing channels and declining real producer, mill-gate and consumer prices in recent years Falling real South African Maize Board export grain prices and evidence of subsidies to commercial Lesotho mills explain these price trends. Changes to the one channel formal marketing system and nationally administered price structure that would encourage an open market system with less restrictive interregional maize trade are recommended.

description: This study is based on two 1991 sample surveys, each of ninety farms, in the predominantly arable region of Chiweshe and in the low rainfall area of Gokwe, where animals are more important. The two samples are reasonably representative of the range of conditions found in the communal areas in Zimbabwe. Programming techniques are used to determine the efficiency levels of the farms in each region. The results show that efficiency is positively related to the numbers of both cows and oxen, with only a few farms in Gokwe possibly having too many animals. Farms in Gokwe are on average about two thirds as efficient as those in Chiweshe, which is a measure of the effects of the poorer climate and soils. Non-farm income is also lower, due to lesser opportunities in the more remote region. In both regions, the majority of farms are too small and the estimates suggest that increasing farm size could almost double productivity.

description: Anomalous coarsening in far-from equilibrium one-dimensional systems is investigated by simulation and analytic techniques. The minimal hard core particle (exclusion) models contain mechanisms of aggregated particle diffusion, with rates epsilon<<1, particle deposition into cluster gaps, but suppressed for the smallest gaps, and breakup of clusters which are adjacent to large gaps. Cluster breakup rates vary with the cluster length x as kx^alpha. The domain growth law x ~ (epsilon t)^z, with z=1/(2+alpha) for alpha>0, is explained by a scaling picture, as well as the scaling of the density of double vacancies (at which deposition and cluster breakup are allowed) as 1/[t(epsilon t)^z]. Numerical simulations for several values of alpha and epsilon confirm these results. An approximate factorization of the cluster configuration probability is performed within the master equation resulting from the mapping to a column picture. The equation for a one-variable scaling function explains the above results. The probability distributions of cluster lengths scale as P(x)= 1/(epsilon t)^z g(y), with y=x/(epsilon t)^z. However, those distributions show a universal tail with the form g(y) ~ exp(-y^{3/2}), which disagrees with the prediction of the independent cluster approximation. This result is explained by the connection of the vacancy dynamics with the problem of particle trapping in an infinite sea of traps and is confirmed by simulation.

description: Since the first investigation of the Hubbard model in the limit of infinite dimensions by Metzner and Vollhardt, dynamical mean-field theory (DMFT) has become a very powerful tool for the investigation of lattice models of correlated electrons. In DMFT the lattice model is mapped on an effective quantum impurity model in a bath which has to be determined self-consistently. This approach lead to a significant progress in our understanding of typical correlation problems such as the Mott transition; furthermore, the combination of DMFT with ab-initio methods now allows for a realistic treatment of correlated materials. The focus of these lecture notes is on the relation between quantum impurity physics and the physics of lattice models within DMFT. Issues such as the observability of impurity quantum phase transitions in the corresponding lattice models are discussed in detail.

description: We interpret the optical spectra of $α$-(BEDT-TTF)$_2M$Hg(SCN)$_4$ (M=NH$_4$ and Rb) in terms of a 1/4 filled metallic system close to charge ordering and show that in the conductivity spectra of these compounds a fraction of the spectral weight is shifted from the Drude-peak to higher frequencies due to strong electronic correlations. Analyzing the temperature dependence of the electronic parameters, we distinguish between different aspects of the influence of electronic correlations on optical properties. We conclude, that the correlation effects are slightly weaker in the NH$_4$ compound compared to the Rb one.

Land Economics/Use

description: Northern Province is predominantly a rural region where agriculture is the dominant sector and plays an important role in the provincial economy. Women are the majority of the poor living in these rural areas and depend heavily on farming. But their agricultural productivity is below potential as they don’t have access to productive assets such as land and credit. This study based on a farm survey undertaken in the seven districts in the former Lebowa homeland in the Northern Province, attempts to identify factors which determine women farmers’s access to more farming land and credit facilities. The results show that most of the women are not satisfied with the size of the land which they own and they have never used farming credit. The probit analysis results show that productivity of the staple crop (maize), more off-farm income and access to credit are the strong determinants of the desire to increase, the size of the farming land. Access to credit is influenced by the first two variables above and farmers membership to agricultural development projects. Better access to and security for farm land, targeted credit and agricultural support services are crucial in improving the quality of women farmers in the province.
FARM LABOUR REMUNERATION, LABOUR LEGISLATION AND COMMERCIAL FARMERS' PERCEPTIONS IN KWAZULU-NATAL

description: A survey was conducted in 1995 among 135 commercial farmers in KwaZulu-Natal to analyse labour remuneration and farmers' perceptions about the impact of labour legislation recently extended to agriculture. Farm labour remuneration normally includes cash wages and payments in kind (such as rations, housing, land use rights and clothing). The study suggests that, all things being equal, farmers who pay relatively lower cash wages tend to provide more rations per worker and allocate more land use rights. Most respondents agreed that there is some need for labour legislation in agriculture, but the majority perceived the present legislation to be time-consuming and costly, and wanted the legislation to be less ambiguous, more flexible and less extensive. Labour legislation has increased transaction and wage costs in farming and could lead to the substitution of own machinery, contract machinery or contract labour for own labour. Survey respondents indicated that, if minimum wages were imposed, cash wages would be paid and perquisites would be charged for. If the minimum wage was set above present wages, labour would be replaced with machinery and contractors. Respondents would prefer an industrial council to determine minimum wages (if they are imposed), accounting for enterprise and regional differences.

description: It is demonstrated a two-photon interfering technique based on polarization-resolved measurements for the simultaneous estimation with the maximum sensitivity achievable in nature of multiple parameters associated with the polarization state of two interfering photonic qubits. This estimation is done by exploiting a novel interferometry technique based on polarization-resolved two-photon interference. We show the experimental feasibility and accuracy of this technique even when a limited number of sampling measurements is employed. This work is relevant for the development of quantum technologies with photonic qubits and sheds light on the physics at the interface between multiphoton interference, boson sampling, multi-parameter quantum sensing and quantum information processing.

description: For a graph $G=(V(G),E(G))$, an Italian dominating function (ID function) of $G$ is a function $f:V(G)\rightarrow \{0,1,2\}$ such that for each vertex $v\in V(G)$ with $f(v)=0$, $f(N(v))\geq2$, that is, either there is a vertex $u \in N(v)$ with $f (u) = 2$ or there are two vertices $x,y\in N(v)$ with $f(x)=f(y)=1$. A function $f:V(G)\rightarrow \{0,1,2\}$ is a covering Italian dominating function (CID function) of $G$ if $f$ is an ID function and $\{v\in V(G)\mid f(v)\neq0\}$ is a vertex cover set. The covering Italian domination number (CID number) $γ_{cI}(G)$ is the minimum weight taken over all CID functions of $G$. In this paper, we study the CID number in graphs. We show that the problem of computing this parameter is NP-hard even when restricted to some well-known families of graphs, and find some bounds on this parameter. We characterize the family of graphs for which their CID numbers attain the upper bound twice their vertex cover number as well as all claw-free graphs whose CID numbers attain the lower bound half of their orders. We also give the characterizations of some families of graphs with small or large CID numbers.

description: This paper has a two-fold contribution, first we demonstrate the relationship of spatial, temporal and residual yield risk estimated from a two-way panel random effects model to asymmetric information with an optional unit provision in the federal crop insurance program. Second, the yield risk components are incorporated in a discrete choice model to examine the presence of asymmetric information due to potential yield switching with optional unit provisions. Empirical application to 1998 U.S. cotton crop insurance data reveals the presence of asymmetric information with optional unit provisions.
Analysis of an integrodifference model for biological invasions with a quasi-local interaction
Creators: name: Merchant, Sandra M.
Publisher: name: University of British Columbia
Year: 2009

description: The behaviour of a new model for the spatial spread of biological invasions with non-overlapping synchronous generations and well-defined dispersal and sedentary stages is examined. In this integrodifference model, competition between conspecifics takes the form of a quasi-local interaction, where the strength of competition between two individuals depends on their physical distance from each other. Both the deterministic model and a stochastic analogue are examined by numerically simulating the spread of a localized initial population over several generations. By modelling intraspecific competition with a quasi-local interaction, the shape of the travelling waves changed significantly from that of the classical model with only local competition, creating more variable and complex wavefront shapes than are possible with the classical model. The addition of quasi-local competition was also found to alter several aspects of the initial behaviour of this model, including the invasion speed and spatial structure, although in the deterministic case the asymptotic invasion speed and population density behind the front of the wave agreed with those of the classical model. In the stochastic analogue, however, the rate of spread of the invasion was found to be considerably lower than that of the classical model, both initially and asymptotically. Furthermore, the speed achieved by the stochastic invasions was found to depend on the parameters of the quasi-local interaction kernel.
