description: The Brazilian poultry chain has been intensely restructured during the last few years to remain competitive in the internal and external markets. Analysis of all the chain levels indicates that the processing segment is characterized by an intense innovation process, in both its product and its processes, resulting in new and improved products and even more automated manufacturing processes. In this context, the poultry processing companies have developed strategies resulting in innovations in the product presentation for the internal consumer, access to new niches in the internal market and adaptations to the demands of the international market. This paper aims to demonstrate the strategies adopted by companies, national and foreign, that are a link in the Brazilian poultry chain. The theoretical bases are marketing and differentiation theory, and industrial organization and productive diversification theory. Some innovation concepts are discussed to understand the innovation dynamics managed by these companies in the processing segment.

description: Frequency instability of superconducting resonators and qubits leads to dephasing and time-varying energy-loss and hinders quantum-processor tune-up. Its main source is dielectric noise originating in surface oxides. Thorough noise studies are needed in order to develop a comprehensive understanding and mitigation strategy of these fluctuations. Here we use a frequency-locked loop to track the resonant-frequency jitter of three different resonator types---one niobium-nitride superinductor, one aluminium coplanar waveguide, and one aluminium cavity---and we observe strikingly similar random-telegraph-signal fluctuations. At low microwave drive power, the resonators exhibit multiple, unstable frequency positions, which for increasing power coalesce into one frequency due to motional narrowing caused by sympathetic driving of individual two-level-system defects by the resonator. In all three devices we probe a dominant fluctuator, finding that its amplitude saturates with increasing drive power, but its characteristic switching rate follows the power-law dependence of quasiclassical Landau-Zener transitions.

description: While anti-reflective properties of pyramid texture are widely used, their use for thermal radiation control has received relatively little attention and the understanding of geometric parameters for design optimization is not well established. Here we use finite-difference time-domain simulations in conjunction with an algorithm to optimize thermal characteristics of micropyramid-textured metallic, ceramic, and polymer materials. Our simulations indicate that the pyramid height-to-base ratio is an effective parameter in developing an engineered thermal response. For nickel, the micropyramids with 2–4 height-to-base ratios over 0.5–4 µm base spans provide near-perfect absorption in 300–2500 nm wavelengths. The electric field analysis shows the optical properties are driven by the effects of localized resonance and field confinement. Our thermal cost function-based optimization has led to micropyramid texture that can have a significant impact on heating or cooling such as the solar absorption increase in nickel from 337 to 982 W/m2, the thermal emission increase in alumina from 106 to 170 W/m2, and the thermal emission increase in PDMS from 160 to 172 W/m2. This work not only provides the understanding of micropyramid properties for thermal radiation control but also presents an algorithmic process that could be used for efficient optical-thermal optimization of geometries beyond micropyramids.

description: We present an initial look at the far infrared-radio correlation within the star-forming disks of four nearby, nearly face-on galaxies (NGC~2403, NGC~3031, NGC~5194, and NGC~6946). Using {\it Spitzer} MIPS imaging and WSRT radio continuum data, we are able to probe variations in the logarithmic 70~$μ$m/22~cm ($q_{70}$) flux density ratios across each disk at sub-kpc scales. We find general trends of decreasing $q_{70}$ with declining surface brightness and with increasing radius. We also find that the dispersion in $q_{70}$ within galaxies is comparable to what is measured {\it globally} among galaxies at around 0.2 dex. We have also performed preliminary phenomenological modeling of cosmic ray electron (CR$e^{-}$) diffusion using an image-smearing technique, and find that smoothing the infrared maps improves their correlation with the radio maps. The best fit smoothing kernels for the two less active star-forming galaxies (NGC~2403 and NGC~3031) have much larger scale-lengths than that of the more active star-forming galaxies (NGC~5194 and NGC~6946). This difference may be due to the relative deficit of recent CR$e^{-}$ injection into the interstellar medium (ISM) for the galaxies having largely quiescent disks.

description: We develop a new technique for computing a class of four-point correlation functions of heavy half-BPS operators in planar N=4 SYM theory which admit factorization into a product of two octagon form factors with an arbitrary bridge length. We show that the octagon can be expressed as the Fredholm determinant of the integrable Bessel operator and demonstrate that this representation is very efficient in finding the octagons both at weak and strong coupling. At weak coupling, in the limit when the four half-BPS operators become null separated in a sequential manner, the octagon obeys the Toda lattice equations and can be found in a closed form. At strong coupling, we exploit the strong Szego limit theorem to derive the leading asymptotic behavior of the octagon and, then, apply the method of differential equations to determine the remaining subleading terms of the strong coupling expansion to any order in the inverse coupling. To achieve this goal, we generalize results available in the literature for the asymptotic behavior of the determinant of the Bessel operator. As a byproduct of our analysis, we formulate a Szego-Akhiezer-Kac formula for the determinant of the Bessel operator with a Fisher-Hartwig singularity and develop a systematic approach to account for subleading power suppressed contributions.

description: This paper introduces habit formation into an otherwise standard model of international trade. Household tastes evolve over time to favor foods consumed as a child. The opening of trade causes preferred goods to rise in price, as these were relatively inexpensive in autarky. Neglecting the correlation between tastes and agro-climatic endowments overstates the short-run nutritional gains from agricultural trade liberalization and masks potential caloric losses for laborers. I examine the predictions of this model of trade with habit formation using household survey data from India, both by looking across Indian regions and by examining the consumption patterns of inter-state migrants.

description: Measuring cosmic shear in wide-field imaging surveys requires accurate knowledge of the redshift distribution of all sources. The clustering-redshift technique exploits the angular cross-correlation of a target galaxy sample with unknown redshifts and a reference sample with known redshifts, and is an attractive alternative to colour-based methods of redshift calibration. We test the performance of such clustering redshift measurements using mock catalogues that resemble the Kilo-Degree Survey (KiDS). These mocks are created from the MICE simulation and closely mimic the properties of the KiDS source sample and the overlapping spectroscopic reference samples. We quantify the performance of the clustering redshifts by comparing the cross-correlation results with the true redshift distributions in each of the five KiDS photometric redshift bins. Such a comparison to an informative model is necessary due to the incompleteness of the reference samples at high redshifts. Clustering mean redshifts are unbiased at $|Δz|<0.006$ under these conditions. The redshift evolution of the galaxy bias can be reliably mitigated at this level of precision using auto-correlation measurements and self-consistency relations, and will not become a dominant source of systematic error until the arrival of Stage-IV cosmic shear surveys. Using redshift distributions from a direct colour-based estimate instead of the true redshift distributions as a model for comparison with the clustering redshifts increases the biases in the mean to up to $|Δz|\sim0.04$. This indicates that the interpretation of clustering redshifts in real-world applications will require more sophisticated (parameterised) models of the redshift distribution in the future. If such better models are available, the clustering-redshift technique promises to be a highly complementary alternative to other methods of redshift calibration.

description: We establish numerical lower bounds for the monochromatic connectivity measure in two dimensions introduced by Sarnak and Wigman. This measure dictates among the nodal domains of a random plane wave what proportion have any given number of holes, and how they are nested. Our bounds provide the first effective estimate for the number of simply connected domains and for those that contain a single hole. The deterministic aspect of the proof is to find a single function with a prescribed zero set and, using a quantitative form of the implicit function theorem, to argue that the same configuration occurs in the zero set of any sufficiently close approximation to this function. The probabilistic aspect is to quantify the likelihood of a random wave being close enough to this function.

description: The study verifies, between march 2005 and march 2006, if there is any difference between the stock yields of a sample of companies listed in Bovespa that adopt the principles of Corporate Governance, in different levels, in relation to the companies of the traditional market. The data were extracted from Economatica’s database; 130 non-financial companies with higher liquidity stock were selected, of which 65 adopt Corporate Governance practices, and 65 operate according to the traditional market. To conduct the study, the Analysis of Variance (ANOVA) and Student’s t test were used. The results show that the mean yield of companies that adopt different Corporate Governance levels was superior to that of the companies which did not adopt these practices. These results demonstrate that a higher level of transparency, and consequently lower information asymmetry, can lead to a better company performance.

description: In the framework of the O(N) three-dimensional effective scalar field model for homogeneous dilute weakly interacting Bose gases we use the 1/N expansion to evaluate, within the large N limit, the parameter r_c which is directly related to the critical chemical potential mu_c. This quantity enters the order-a^2 n^{2/3} coefficient contributing to the critical temperature shift Delta T_c where a represents the s-wave scattering length and n represents the density. Compared to the recent precise numerical lattice simulation results, our calculation suggests that the large N approximation performs rather well even for the physical case N=2. We then calculate the same quantity but using different forms of the optimized perturbative (variational) method, showing that these produce excellent results both for the finite N and large-N cases.

description: Reversible entanglement transfer between light and matter is a crucial requisite for the ongoing developments of quantum information technologies. Quantum networks and their envisioned applications, e.g., secure communications beyond direct transmission, distributed quantum computing or enhanced sensing, rely on entanglement distribution between nodes. Although entanglement transfer has been demonstrated, a current roadblock is the limited efficiency of this process that can compromise the scalability of multi-step architectures. Here we demonstrate the efficient transfer of heralded single-photon entanglement into and out-of two quantum memories based on large ensembles of cold cesium atoms. We achieve an overall storage-and-retrieval efficiency of 85% together with a preserved suppression of the two-photon component of about 10% of the value for a coherent state. Our work constitutes an important capability that is needed towards large scale networks and increased functionality.

description: The evolution of a Raman coupled three-level lambda atom with two quantized cavity modes is studied in the large detuning case; i.e. when the upper atomic level can be adiabatically eliminated. Particularly the situation when the two modes are prepared in initial coherent or squeezed states, with a large average number of photons, is investigated. It is found that the atom, after specific interaction times, disentangles from the two modes, leaving them, in certain cases, in entangled Schrodinger cat states. These disentanglement times can be controlled by adjusting the ratio between average numbers of photons in the two modes. It is also shown how this effective model may be used for implementing quantum information processing. Especially it is demonstrated how to generate various entangled states, such as EPR- and GHZ-states, and quantum logic operations, such as the control-not and the phase-gate.

We have computed models taking into account rotation for increasing rotational velocities. We investigate the relation between the fundamental radial mode and the first overtone in the framework of Petersen diagrams. The effects of rotation on such diagrams, which become important at rotational velocities above 150 km/s, as well as the domain of validity of our seismic tools are discussed. We also investigate the radial and non-radial modes in order to constrain models fitting the five most dominant observed oscillation modes.

Unlike other approaches, only real observation data is used during training. Despite being trained on a relatively small sample, the method shows good results on real data from the Open Supernovae Catalog. We also investigate model transfer from the PLAsTiCC simulations train dataset to real data application, and the reverse, and find the performance significantly decreases in both cases, highlighting the existing differences between simulated and real data.

description: The growth of the world’s organic food market in the last ten years has been raising the demand for studies related to this theme. Supermarkets have been proving themselves relevant actors in the distribution of these products in Brazil and in the external market. This paper aims to describe the characteristics of the consumer behavior of organic fruits and vegetables in the city of Uberlândia in the state of Minas Gerais. More specifically, it aims to evidence this behavior through the enchainment of attributes, consequences (benefits that these attributes provide) and the consumers’ personal values. 30 in-depth interviews were done using the laddering qualitative technique, which is based on the means end chain theory. The results show, emphatically, the consumers’ awareness regarding individual well being and its maintenance in the long run through quality of life and a healthy lifestyle, classified as individual values according to the Schwartz scale. Finally, we present these consumers’ dominant perceptions from the enchainment between the attributes, consequences and values obtained in the research.
Examining multiple discourses of community development in a collaborative community-based organization
Creators: name: Millar, Sydney Nicole
Publisher: name: University of British Columbia

description: In an effort to increase the quality and relevance of the programs, municipal recreation departments are partnering with community-based organizations and community members through a community development approach (Hutchison & Nogradi, 1996; Millar & Frisby, 2002; Searle & Brayley, 2000). However, the use of community development across diverse sectors has created multiple discourses as practitioners translate theory into practice and attempt to resolve conflicts between social justice goals and financial imperatives, creating ambiguity in collaborative contexts. Therefore, the primary purpose of this study was to examine the multiple discourses of community development used by community workers involved in a collaborative community-based organization designed to increase the involvement of women in low income in recreation decisionmaking and participation. A secondary purpose was to examine the implications of multiple discourses in this context. The research methods involved three data collection techniques in two phases over a 20 month period. Two semi-structured, one-on-one interviews were conducted with three community workers representing a municipal recreation department, a women's centre, and a family service agency. This data was enhanced with field notes and observations of meetings. Data analysis was assisted by Atlas.ti, a qualitative computer software program. The findings revealed a unique discourse of community development used by each research participant that had implications for how community development was conceptualized, the goals identified, and the role of the community worker in the process. For each discourse, central dimensions were identified and one significant tension was discussed. The analysis also explored the influence of personal experience and organizational context, and examined inconsistencies, contradictions, and resistance to other discourses that demonstrated the complexities involved in community development practice (Alvesson & Skoldberg, 2000; Weedon, 1997). This study also identified three implications of multiple discourses that both enhanced and inhibited collaboration. These findings demonstrated the complexities involved and the importance of communication and new strategies to decrease conflict and develop shared meanings to accomplish social justice goals. Given the dynamic tensions described in this study, recommendations for future research and practice were provided.

description: We present the results from XMM-Newton observations of the highly optically polarized broad absorption line quasar (BALQSO) CSO 755. By analyzing its X-ray spectrum with a total of ~3000 photons we find that this source has an X-ray continuum of `typical' radio-quiet quasars, with a photon index of Gamma=1.83^{+0.07}_{-0.06}, and a rather flat (X-ray bright) intrinsic optical-to-X-ray spectral slope of alpha_ox=-1.51. The source shows evidence for intrinsic absorption, and fitting the spectrum with a neutral-absorption model gives a column density of N_H~1.2x10^{22} cm^{-2}; this is among the lowest X-ray columns measured for BALQSOs. We do not detect, with high significance, any other absorption features in the X-ray spectrum. Upper limits we place on the rest-frame equivalent width of a neutral (ionized) Fe Ka line, <=180 eV (<=120 eV), and on the Compton-reflection component parameter, R<=0.2, suggest that most of the X-rays from the source are directly observed rather than being scattered or reflected; this is also supported by the relatively flat intrinsic alpha_ox we measure. The possibility that most of the X-ray flux is scattered due to the high level of UV-optical polarization is ruled out. Considering data for 46 BALQSOs from the literature, including CSO 755, we have found that the UV-optical continuum polarization level of BALQSOs is not correlated with any of their X-ray properties. A lack of significant short- and long-term X-ray flux variations in the source may be attributed to a large black-hole mass in CSO 755. We note that another luminous BALQSO, PG 2112+059, has both similar shallow C IV BALs and moderate X-ray absorption.

description: The complexity of many-body quantum wave functions is a central aspect of several fields of physics and chemistry where non-perturbative interactions are prominent. Artificial neural networks (ANNs) have proven to be a flexible tool to approximate quantum many-body states in condensed matter and chemistry problems. In this work we introduce a neural-network quantum state ansatz to model the ground-state wave function of light nuclei, and approximately solve the nuclear many-body Schrödinger equation. Using efficient stochastic sampling and optimization schemes, our approach extends pioneering applications of ANNs in the field, which present exponentially-scaling algorithmic complexity. We compute the binding energies and point-nucleon densities of $A\leq 4$ nuclei as emerging from a leading-order pionless effective field theory Hamiltonian. We successfully benchmark the ANN wave function against more conventional parametrizations based on two- and three-body Jastrow functions, and virtually-exact Green's function Monte Carlo results.

description: We present calculation of the high pressure crystal structures in selenium, including rational approximants to the recently reported incommensurate phases. We show how the incommensurate phases can be intuitively explained in terms of imaginary phonon frequencies arising from Kohn anomalies in the putative undistorted phase. We also find inconsistencies between the calculated and experimental Se-II phase - the calculations show it to be a metastable metal while the experiment finds a stable semiconductor. We propose that the experimentally reported structure is probably in error.

description: This paper discusses the conditions of birth and growth of business networks in the veterinary drugs sector based on Brazilian examples examined by the authors. The beginnings of business networks are approached from two paradigms, one advocating the idea that the birth and growth of networks depend on some variables’ historical processes which define social networks, such as trust, cooperation and commitment, and another postulating that these attributes are not necessary for the formation of networks, it being sufficient to have only consistent economic expectations and a proper agreement. The aim of this paper was to assess which of the two network paradigms (the social paradigm and the business paradigm) best explains the birth of two networks in the veterinary drugs sector. An exploratory study was conducted, using the case study methodology, to collect and analyze information from these two types of network. The analyses of the two starting networks (one a failure and the other a case of initial success) confirm the importance of trust, cooperation and commitment in relationships. The final discussion indicates some theoretical and managerial paths that can be followed in social networks as a backdrop for business networks in the agricultural sector.

description: We study coupled channel effects upon isospin I=2 and I=0 $ππ$ S-wave interaction. With introduction of the $ππ\toρρ\toππ$ coupled channel box diagram contribution into $ππ$ amplitude in addition to $ρ$ and $f_2 (1270)$ exchange, we reproduce the $ππ$ I=2 S-wave and D-wave scattering phase shifts and inelasticities up to 2 GeV quite well in a K-matrix formalism. For I=0 case, the same $ππ\toρρ\toππ$ box diagram is found to give the largest contribution for the inelasticity among all possible coupled channels including $ππ\toωω\toππ$, $ππ\to K \bar{K}\toππ$. We also show why the broad $σ$ appears narrower in production processes than in $ππ$ scattering process.

description: A key problem in constrained random verification (CRV) concerns generation of input stimuli that result in good coverage of the system's runs in targeted corners of its behavior space. Existing CRV solutions however provide no formal guarantees on the distribution of the system's runs. In this paper, we take a first step towards solving this problem. We present an algorithm based on Algebraic Decision Diagrams for sampling bounded traces (i.e. sequences of states) of a sequential circuit with provable uniformity (or bias) guarantees, while satisfying given constraints. We have implemented our algorithm in a tool called TraceSampler. Extensive experiments show that TraceSampler outperforms alternative approaches that provide similar uniformity guarantees.

description: This work shows that the political and legal resources available to citrus farmers have become as strategic as financial, technological and organizational resources. The study presents an analysis of the Brazilian citrus business governance, which is defined by the use of different strategies among citrus farmers and processing plants: the citrus farmers and their main association use political resources, while some big juice processing plants resort to legal resources. This opposition represents a new obstacle to the achievement of positive results by citrus farmers in the current power network. Court orders demonstrate that orange supply contracts have become a fundamental empowering instrument in the sector, leading to strategic gains for the juice processing plants after four years of significant political conquests by citrus farmers, especially in Sao Paulo state.

description: The aim of this study is to identify the competition pattern in the Brazilian special cheese industry, and the strategic groups of this market. Based mainly on the Industrial Organization Theory, a qualitative study was conducted, supported by primary and secondary data. The primary data were obtained through interviews with six managers of Brazilian special cheese companies, and the secondary data were obtained from websites, company documents and specialized publications. The results point to the increasing importance of the price variable, related to market growth in recent years, which attracted companies with more effective production and logistics structures. Based on the characteristics and strategies of companies, four strategic groups were identified: a) medium sized companies with large market penetration; b) small companies focused on the special cheese market and located in traditional production regions of Minas Gerais State; c) single-product companies, with high levels of vertical integration; and d) transnational companies that produce special cheese in several countries.

description: Genus Bysone Stock & Humes, 1970
Diagnosis. Body of female curved ventrally. Prosome expanded posteriorly; third and fourth pedigerous somites or fourth pedigerous somite alone forming brood pouch. Freeurosome 5-segmented. Caudal rami armedwith 6 setae. Rostrum present. Antennule 6-segmented. Antenna 4-segmented with terminal claw. Mandible consistingof coxal gnathobase with broad cutting margin, and palp comprising basis, 1-segmented exopod bearing 4 setae, and 2-segmented endopod bearing 2 and 5 setaeonfirst and second segments, respectively. Maxillule armed with 7 to 9 setaeon arthrite, 1 on endite, 2 on epipodite, 3 on basis, 3 onexopodand 2 on endopod. Maxilla 4- or 5- segmentedwith 2- or 3-segmented endopod. Maxilliped unsegmented, armed with 5 to 8 setae medially and 1 seta subdistally on outer margin. Leg 1 with 2-segmented rami; inner coxal seta present; basis without inner distal spine; first exopodal segment lacking inner seta. Legs 2–4 with 3-segmented exopods and 2-segmented endopods. Inner coxal seta present or absent on legs 2–4. Leg 5 reduced; exopod lobate or digitiform, armed with 2 setae distally.
Type species. Bysone operculatus Stock & Humes, 1970, by original designation.
Remarks. Like Thoracodelphys, Bysone carries 2 and 5 setae, respectively, on the first and secondendopodal segments of the mandible, and 3 and 2 setae, respectively, on the exopod and endopod of the maxillule. It also has a reduced leg 5, a reduced number of antennular segments, and a maxilliped that is similar to that of Thoracodelphys. Unlike Thoracodelphys, the body of Bysone is not dorsoventrally depressed, the exopod of leg 1 is only 2- segmented, and the inner coxal seta is present at least on leg 1. In addition, the setation of the swimming legs is better developed so that the distal endopodal segments of legs 1 and 4 are armed with 7 setae (in Thoracodelphys the same segment is armed invariably with only 6 setae in leg 1 and with only 4 setae in leg 4). Finally, the bifurcate distal process on surface of the second exopodal segment of legs 2–4, which is typical of species of Thoracodelphys, is absent in Bysone.

description: Cotton is an unquestioned success of Zambia’s turn towards a market economy. After privatization in late 1994, seed cotton production rose from 32,000 metric tons (mt) to about 180,000 mt a decade later (three-year averages centered on 1994 and 2005). The number of farmers involved in the sector grew similarly, yields trended upwards (though slowly), and the country dramatically improved the quality of its lint, becoming the outstanding performer in Sub-Saharan Africa in this regard by the mid-2000s. Yet the sector has experienced two serious crashes since reform, both involving rampant credit default by farmers supported with seasonal input credit by ginning companies.

description: The aim of this work is to analyze the model of consumer involvement with organic fruits and vegetables. An empirical survey was carried out using a 371 sample size questionnaire, which allowed for both path and multigroups analysis to be done. Based on the results obtained, we can affirm that the level of motivation to consume organic fruits and vegetables is intermediate, as the predominant motives are safety and self-realisation, and the volition model follows an inverse theoretical learning process. Furthermore, there is more than one model, since both gender and income influence significantly the involvement with organic food. Contradicting the predominant theoretical paradigm, this work tries to develop practical implications for organic food communication campaigns.

description: The objective of this paper is to study the socio-environmental management of a company in the cellulose industry based on the organization’s interaction in the social field. To achieve this, a theoretical-methodological model, based on an interpretative approach and on the understanding of environmental management as a social practice, was used. Triangulation of document analysis techniques and deep semi-open interviews were carried out. To interpret the results, content analysis was used to identify how managers understand the socially constructed relations between the organization and the environment. The results of this research also show that the organization is seeking to implement management practices that guarantee the efficiency of its production process while attempting to mitigate its environmental impacts, consolidating its image as an open and transparent company that operates according to the philosophy of corporative social responsibility.
