description: Coupled Ginzburg-Landau equations appear in a variety of contexts involving instabilities in oscillatory media. When the relevant unstable mode is of vectorial character (a common situation in nonlinear optics), the pair of coupled equations has special symmetries and can be written as a vector complex Ginzburg-Landau equation. Dynamical properties of localized structures of topological character in this vector-field case are considered. Creation and annihilation processes of different kinds of vector defects are described, and some of them interpreted in theoretical terms. A transition between different regimes of spatiotemporal dynamics is described.

description: Commercialization through cooperatives has the potential to reduce transaction costs and improve bargaining power of farmers vis-à-vis the market. The objective of this study is to evaluate the probability for Ethiopian agri-cooperative to engage in collective marketing activities over time, given market and governance characteristics. Using a sample of 200 agricultural cooperatives from the Ethiopian Highlands, the analysis reveals that collective marketing faces cyclical challenges related to increased competition. Empirical results also suggest that among Ethiopian cooperatives, those located in the Northern regions of Tigray and Amhara, and/or established upon the voluntary initiative of farmers, are more likely to engage in sustainable collective marketing activities over time. The study concludes with implications for policy and further research.

description: Zooplankton fecal pellets constitute a major component of passively sinking particles in the ocean. The sinking of zooplankton fecal pellets provides an efficient vehicle for the transfer and sequestration of particulate organic carbon in the deep sea, which has been widely reported in different ocean regions. However, most existing studies focus on the sinking flux of fecal pellets within the upper ocean, while the lower mesopelagic and bathypelagic zones are rarely investigated. Here, we report the spatiotemporal flux variation of zooplankton fecal pellets collected by two sediment traps deployed in mesopelagic and bathypelagic zones (500 m and 2190 m, respectively) of the southern South China Sea from June 2020 to May 2023. The average fecal pellet numerical flux is 3.21*104and 4.64*104 pellets m-2 d-1 at 500 m and 2190 m, respectively, corresponding to an average fecal pellet carbon flux from 0.43 to 0.84 mg C m-2 d-1 at these two depths. Fecal pellet fluxes display distinct seasonal patterns due to the control of the East Asian monsoon system, with higher fluxes in winter and spring, and lower fluxes in summer and autumn. Higher fecal pellet fluxes combining with the presence of extra-large pellets are found in bathypelagic zone, which is attributed primarily to in-situ reworking and repackaging of sinking particulate matter by deep-dwelling zooplankton communities, as well as lateral inputs from adjacent high productive continental coasts and shelves. We compare our results with global deep-sea (>500 m) fecal pellet flux data reported from different sediment-trap stations with distinct marine primary productivity and zooplankton biomass. Furthermore, we will report on the state of our progress on carbon isotope analysis (13C, 14C) for disentangling the source-to-sink dynamics of fecal pellets and its role in the deep-sea carbon export and sequestration.

description: Cet article retrace comment la circulation transnationale du hip-hop a été le moteur d'identification à une identité noire globale, et simultanément, le levier de production de particularismes et de singularités culturelles locales. A partir de différentes ethnographies du hip-hop dans le monde, il décrit tout d'abord l'alignement des luttes pour l'autonomie, l'indépendance ou la reconnaissance que la connexion au hip-hop a suscité chez différents groupes s'identifiant comme noirs, dans la continuité d'une plus longue histoire de dialogues avec des expressions culturelles en circulation dans « l'Atlantique noir ». Dans un second temps, il démontre que le message de fierté et de modernité noire porté par le hip-hop a aussi été le levier de propositions identitaires originales et le creuset d'affirmations de localité autour de la blackness. Dans la continuité de certains théoriciens de la diaspora noire, cet article propose le concept de « dialogismes transhistoriques » pour mettre l'accent sur les voyages, les discussions, les rencontres et les médias au travers desquels s'opèrent les processus conjoints de globalisation et de localisation de la blackness, via le hip-hop et d'autres genres musicaux. mots-clés : rap, blackness, anthropologie, dialogisme, identité noire, globalisation.
description: Transhistorical Dialogisms. For an anthropology of global blackness and hip-hop This article explores how the transnational circulation of hip-hop has inspired identification with global blackness, while at the same time playing a key role in the production of local cultural particularisms and singularities. Drawing on different ethnographies of hip-hop around the globe, the article first describes the series of struggles for autonomy, independence or recognition that the connection to hip-hop has elicited among different groups identifying themselves as Black, in continuity with a longer history of cultural dialogue circulating in the "Black Atlantic". Secondly, the article demonstrates that the message of Black pride and Black modernity carried by hip-hop has also constituted fertile ground for original identity constructions and local cultural particularisms. Following scholars of the Black diaspora, the article proposes the concept of "transhistorical dialogisms" to emphasize the travels, discussions, encounters and media through which the joint processes of globalization and localization of blackness take place, via hip-hop and other musical genres. keywords : rap, blackness, anthropology, dialogism, Black identity, globalization

description: Several lines of evidence point to a relationship between gamma-ray bursts (GRBs) and the high mass stars that explode as supernovae. Arguments that GRB sources accelerate cosmic rays (CRs) are summarized. High-energy neutrino detection from individual GRBs would mean that they are hadronically dominated, that is, that the amount of energy deposited in the form of nonthermal hadrons in GRB blast waves greatly exceeds the radiated energy inferred from their photon emission spectra. Such a detection would make GRBs the favored candidate sources of ultra-high energy and super-GZK CRs. Cascade radiation induced by high-energy hadrons could be detected from GRBs with gamma-ray telescopes.

Surtout, il interroge comment ces pratiques, symboliquement et concrètement, se négocient entre des limites fluides. Les rappeurs essayent de concilier, entre autres, et non sans mal, expression débridée inspirée du hip-hop global et acceptation locale de leurs attitudes, « identité » ou « authenticité » hip-hop, enjeux de carrière et légitimité socioculturelle, toutes choses inscrites dans des dynamiques négociées de co-construction de sens. Une telle perspective d'analyse nous met au défi de réinterroger ces constructions et expressions du hip-hop dans le contexte du Sénégal en dialogue avec le monde. mots-clés : Hip-hop, rap Galsen, Keur Gui, Fou Malade, transculturel.
description: Transcultural constructions and expressions of rap Galsen : an analysis based on the cases of Keur Gui Crew and Fou Malade This article seeks to reconsider the evolution of hip-hop in contemporary Senegal, broadening the reflection to examine how the practices of rappers that present themselves as “moral entrepreneurs” draw on transcultural repertoires and multiple registers. Above all, this article analyses how these practices are symbolically and concretely negotiated between fluid limits. Rappers are trying to reconcile, although not without difficulty, an unbridled expression of globally-inspired hip-hop and local acceptance of their attitudes, hip-hop « identity » or « authenticity », their career issues and socio-cultural legitimacy, all of this being the result of a co-construction of meaning. This analytic perspective invites us to re-examine these constructions and expressions of hip-hop in the context of a Senegal that is in dialogue with the world. keywords : Hip-hop, Galsen rap, Keur Gui, Fou Malade, transcultural.

description: The historical development and performance of rural supply and marketing cooperatives (SMCs) in China are examined and linked to various reform periods. SMCs suffered a loss of focus on members as well as member control during several periods of reform and experienced declining financial performance during the most recent reform period. A number of factors related to this decline are presented, including ineffective reforms, lack of accountability and transparency, limited focus on member needs, a negative image for cooperatives, and poor understanding of contemporary cooperative management and governance practices.

description: A morphometric characterization study was conducted using purebred Baoulé cattle and two crossbreds’ populations in the southwestern region of Burkina-Faso. A total of 421 cattle, including 266 crossbreds from the department of Kampti and Loropeni and 155 purebred Baoulé, from the department of Bouroum-Bouroum were measured for quantitative and qualitative traits. The quantitative traits were analyzed by fitting the linear model including genotype-location, sex, age and all two-way interactions. The chi square test was performed for qualitative traits. The results provide evidence for difference between purebred and crossbred populations, and among crossbreds for all traits. The genotype-location effect showed that facial length, distance between horn tips, ear length and chest width differed between purebred and crossbred populations. For qualitative traits, coat color and horn shape showed large variation between Baoulé and crossbreds. These results will serve as basis for further characterization, conservation and improvement strategies for purebred and crossbred populations.
Decoherence and Records for the Case of a Scattering Environment

description: Using non-relativistic many body quantum field theory, a master equation is derived for the reduced density matrix of a dilute gas of massive particles undergoing scattering interactions with an environment of light particles. The dynamical variable that naturally decoheres (the pointer basis) is essentially the local number density of the dilute gas. Earlier master equations for this sort of system (such as that derived by Joos and Zeh) are recovered on restricting to the one-particle sector for the distinguished system. The derivation shows explicitly that the scattering environment stores information about the system by ``measuring'' the number density. This therefore provides an important example of the general connection between decoherence and records indicated by the decoherent histories approach to quantum theory. It also brings the master equation for this system into a form emphasizing the role of local densities, which is relevant to current work on deriving hydrodynamic equations from quantum theory.

description: readily available, and of the quality and diversity consumers expect. However, prevalent information systems (IS) of companies in the food industry are not ready to support further significant improve-ments. They especially lack the capability to exchange relevant information in an efficient manner. Since recently, two major developments can be observed from IS perspective: the spreading of ser-vice-oriented architectures (SOA) as well as an increase in mass serialization (due to public and pri-vate traceability requirements, e.g.). So far, though most important due to food safety, a growing need to become more efficient as well as an increasing information demand of consumers, the food sector has attracted little attention in literature concerning an analysis about the potential of both service-orientation and the Electronic Product Code (EPC) Network. This is why this paper will inves-tigate to which extent these two developments can contribute to facilitate food companies’ IS help-ing them to maintain their competiveness. As a starting point, the research paper will depict the state of the art including SOA and the EPC Net-work. After describing the research approach, it will proceed with a characterisation of the food sec-tor including an examination why there is need for action. Based on current research findings as well as experience gathered in recent projects, the paper will investigate the application of the EPC Net-work with its three major components, i. e. EPCIS (EPC Information Services), ONS (Object Name Service) and the EPC Discovery Services, as part of future IS architectures in this sector. The paper will close with a discussion whether the envisioned IS architecture is appropriate to accomplish the previously identified challenges and requirements in the food sector in a more agile, efficient and effective way. What is more, it will highlight the most pressing challenges and provide an outlook as to the following steps of the research.

description: A complex economic evaluation of fairs / exhibitions can be considered as a novelty in the current literature. In this novel approach, each stakeholder group involved in a fair is evaluated in numerical terms, taking into account the specific cash inflow and outflow categories of that group. The net cash flow is considered as the economic value since it filters out the accumulations. Adding together all the categories, the so-called complex economic value and effectiveness is established regarding the fair surveyed. A numerical model entitled KAVA was developed in order to carry out the calculations for the complex economic effectiveness of the fair. A practical example of using the model is also shown in the paper.

description: Mantle plumes are hot, buoyant upwellings that rise from Earth’s core-mantle-boundary (CMB) at ~2891 km depth to its surface1. As they ascend towards the lithosphere – our planet’s rigid outermost shell – the decreasing pressure facilitates decompression melting, resulting in surface volcanism that shows no obvious association with plate boundaries1-3. This so-called hotspot volcanism, commonly identified in oceanic regions, occurs less frequently within continental interiors due to the presence of a thicker lithosphere, which limits plume ascent and associated decompression melting4. However, given challenges in resolving mantle plumes with geophysical imaging5,6, it remains uncertain whether limited continental volcanism implies few sub-continental mantle plumes. Here, we present inter-disciplinary evidence revealing the first clear example of an amagmatic “ghost” plume in eastern Oman – the Dani plume. Despite lacking present-day surface volcanism7,8, this plume is robustly imaged using P- and S-wave arrival-time residuals from distant earthquakes, recorded by a dense regional seismic network. The imaged low-velocity structure is overlain by positive present-day residual topography9,10, in a region enigmatically uplifted since the late Eocene11,12 (~40 Ma). Our analyses of kinematic reconstructions demonstrate that asthenospheric flow associated with the Dani plume modified Indian-plate motion in the late Eocene, allowing us to bound the likely arrival time of this plume beneath the lithosphere. Our findings imply that other “ghost” plumes likely exist on Earth, for example beneath amagmatic topographic swells on the African continent, whilst there is strong evidence for their existence in the recent geological past13,14,15,16. Besides offering an approach to identify hidden continental plumes, both at the present-day and via Earth’s geological record, our study suggests that CMB heat-flux estimates should be revised upwards, with implications for thermal and core evolution models.

description: The physical situation of the collision and subsequent interaction of plane gravitational waves in a Minkowski background gives rise to a well-posed characteristic initial value problem in which initial data are specified on the two null characteristics that define the wavefronts. In this paper, we analyse how the Abel transform method can be used in practice to solve this problem for the linear case in which the polarization of the two gravitational waves is constant and aligned. We show how the method works for some known solutions, where problems arise in other cases, and how the problem can always be solved in terms of an infinite series if the spectral functions for the initial data can be evaluated explicitly.

description: Serbian honey producers are exposed to the increased international competition of recent years. To face up to the new changes, producers are progressively using diversification strategies, such as direct sales and production diversification. The direct sales strategy allows the producers to increase the product added value, while diversification aims to offer new products to the consumers. The aim of this paper is to analyse the honey marketing strategy of Serbian honey producers. The first part of the paper analyses the structure of production costs, production performances as well as the determinants of the honey supply. In the second part of the paper, analysis is focused on the determinants of direct sales. Finally, in the third part of the paper, diversification strategies are discussed. The data for this research has been obtained on the basis of a representative sample consisting of 84 Serbian honey producers interviewed in 2011 and 2012. The results show that the Serbian honey producers operate with more or less similar production costs and with production performances that do not differ significantly. They use direct marketing for two reasons: firstly, it affords personal contact with consumers, and secondly, they aim to decrease the transaction costs, thereby keeping a higher share of the product’s final value. Offering new products to consumers is an attempt to create additional product demand.

description: Recent crises in the agricultural sector, such as the 2011 German dioxin scandal and deaths from EHEC or the last swine fever outbreak in Germany in 2006, have caused immense economic damage. As a result, German veterinary authorities at the district, state, and federal levels have been put in charge as crisis managers and leaders of active preventative organizations. To perform their tasks successfully, they require effective communication skills as well as close cooperation with stakeholders in the agribusiness sector. However, despite clear evidence that identifies these relationships as crucial, there is only very little research that directly addresses communication quality and intensity of public authorities responsible for food safety. The relevant literature so far primarily deals with the technical design and implementation of new information and communication systems. However, it often fails to address the particular needs and communication behaviour of individual users. It is the objective of this study to identify determinants of communication quality and to differentiate between types of communicators in order to shed light on the construct of communication behaviour in veterinary authorities. To do so, the determinants of the quality of communication between public authorities and their external stakeholders were identified based on a causal model. These determinants were used as cluster-building variables in a cluster analysis to determine different types of communicators in veterinary services. The data reveals that the personal aspects of communication are of greater relevance than its content. This knowledge could be helpful to identify measures that could be implemented in order to improve the quality of communication of veterinary authorities
The influence of direct support under common agricultural policy on farm incomes in Poland

description: The main objective of the paper is the analysis of changes on the level of income of agricultural producers, which took place in Poland in the early years of the accession to the EU, as well as a determination of the scale of the impact of financial support under the Common Agricultural Policy on the farm income situation. Poland’s membership in the EU gives rural farms opportunities to improve their economic situation. Financial aid, mainly in the form of a direct payment, has been the main factor determining the economical status of rural farms, whilst the other income making factors, such as improved productivity and increased agricultural production have played a much smaller role. The increase in revenue has enabled farmers not only to increase current expenditures, but also to carry out modernization efforts, which will determine the future economic and structural situation of the Polish agricultural sector and its competitiveness. However, a strong differentiation in terms of the economic situation of rural farms according to their size and specialization in production was also noticed. As a result, there is a still large number of farms in which the revenues received by farmers are insufficient to assure them adequate life standard. Therefore such farms are not able to both develop and invest. Only economically strong rural farms with high production potential have such opportunities, meaning that EU support will never be able to fully minimize the effects of small-scale production or to offset the insufficient efficiency and productivity of production factors.

description: We report an optical homogeneous linewidth of 580 $\pm$ 20 Hz of Er$^{3+}$:Y$_2$O$_3$ ceramics at millikelvin temperatures, narrowest so far in rare-earth doped ceramics. We show slow spectral diffusion of $\sim$2 kHz over a millisecond time scale. Temperature, field dependence of optical coherence and spectral diffusions reveal the remaining dephasing mechanism as elastic two-level systems in polycrystalline grain boundaries and superhyperfine interactions of Er$^{3+}$ with nuclear spins. In addition, we perform spectral holeburning and measure up to 5 s hole lifetimes. These spectroscopic results put Er$^{3+}$:Y$_2$O$_3$ ceramics as a promising candidate for telecommunication quantum memories and light-matter interfaces.

description: Quality assurance and labeling play an important and increasing role in firms’ marketing strategies. In almost all cases, a price incentive has been stressed as the major incentive for firms to participate in such schemes. We argue here that important non-price incentives for participation in quality labeling may exist, too. In German retailing, it can be observed that discount retailers are listing more and more foods with quality labels. Processors may then participate in voluntary quality labeling in order to enter the large and growing market of discount retailers. The price-premium versus the market-entry hypothesis are analyzed theoretically. We investigate then in an empirical hedonic pricing model for the German fruit juice market and for participation in the quality label of the Deutsche Landwirtschafts-Gesellschaft (DLG) which of the two hypotheses is consistent with the data. There is strong support for the market-entry hypothesis.

description: An emulsion-based injection molding process has been reported for the preparation of ceramic foam spheres from kaolin and alumina. The foam spheres produced from kaolin alone cracked during sintering due to extensive shrinkage and an excessive glass phase. Incorporation of a minimum of 10 wt% alumina in kaolin prevented the cracking of foam spheres during sintering by promoting secondary mullite growth, which decreases both the glass phase concentration and sintering shrinkage. Foam spheres with an interconnected cellular structure having open porosities, average cell sizes and diametrical compressive strengths in the ranges of 76.5 to 82.7 vol.%, 6.8 to 9.2 μm and 1.65 to 0.93 MPa, respectively, were produced from emulsions prepared from hydrogenated vegetable oil and aqueous clay slurries. The interconnected open cell structure and small cell size enabled fast absorption and 100% retention of urea solution for N2O4 scrubber application. The urea solution absorption capacity (71.5 to 80 vol.%) of the foam spheres was much higher than the capacity (45.6 vol.%) of the porous clay ceramic media currently used in N2O4 scrubbers.

description: Drylands cover almost half of Earth’s land surfaces, supporting ~30% of the world’s population. The International Panel on Climate Change predicts increasing aridification and expansion of drylands over the course of this century. As we approach new climate states without societal precedent, Earth’s geological past may offer the best tool to understand hydroclimate change under previously, allowing us to elucidate responses to external forcing. Paleo-records from previously warm and high-CO2 periods in Earth’s past, such as the mid-Pliocene (~3 Ma), point towards higher humidity in many dryland regions. 

Here, we examine desert speleothems from the hyper-arid desert in central Arabia, part of the largest near-continuous chain of drylands in the world, stretching from north-western Africa to the northern China, to elucidate substantial and recurrent humid phases over the past 8 million years. Independent quantitative paleo-thermometers suggest that mean annual air temperatures in central Arabia were approximately between 1 to 5 °C warmer than today. The analyses of the isotopic composition (δ18O and δ2H) of speleothem fluid inclusion waters, representing ‘fossil rainwater’, reveal an aridification trend in Arabia from the Late Miocene to Late Pleistocene during Earth’s transition from a largely ‘ice-free’ northern hemisphere to an ‘ice-age’ world. Together, our data provide evidence for recurrent discrete wetter intervals during past warmer periods, such as the Pliocene. Data-model comparisons allow us to assess the agreement between our paleoclimate data and climate model output using the HadCM3 isotope-enabled model simulations during past ‘warmer worlds’ – namely the mid-Piacenzian warm period (3.264 to 3.025 Ma). To assess the hydroclimate response to external forcing, we examine model output from a series of sensitivity experiments with different orbital configurations allowing us to postulate the mechanisms responsible for the occurrence of humid episodes in the Arabian desert, with potential implications for other dryland regions at similar latitudes. Together, our approach unveils the long-term controls on Arabian hydroclimate and may provide crucial insights into the future variability.

description: The branding strategy is based on future goals relating to clients, aimed at increasing awareness of the brand, creating a positive brand image and establishing a preference for the brand and ensuing brand loyalty. A brand is a very important factor for competitiveness and establishes a leadership position in the market, given the major impact that this form of intellectual property has on the perception of consumers and the success of innovative products on the market. The bottled water market has increased by about 35% in the last five years on the global level, dictated by young consumers who are becoming increasingly aware of the significance of proper nutrition in maintaining health. The research presents qualitative information on the market value of bottled water brands, the general characteristics of retailers, as well as on their target customers. The main task of this paper is to confirm the usefulness of marketing research in modern business as well as to present the benefits of brand value measurement to current or future brand owners. It is to be hoped that the results presented in this paper may serve as a good basis for upgrading marketing activities, based on a better understanding of target customers and their particular needs, through better communication for the purpose of stronger corporate branding.

description: À l'aune des 30 ans du « rap Galsen », l'article explore les tensions entre générations de rappeurs à travers le prisme de l'ostentation matérielle. Cette exploration permet de restituer les processus de différenciation à l'œuvre dans l'affirmation d'un rap "local" au Sénégal et de revisiter les frontières opérées avec ce qui serait de l'ordre du "global". Je montrerai ainsi que les pratiques d'ostentation matérielle dans le rap au Sénégal s'inscrivent dans des transformations du genre musical rap à l'échelle mondiale. Plutôt que de chercher à « imiter les Américains », ces artistes de la « nouvelle génération » se positionnent d'abord à l'intérieur d'une scène musicale. Cette analyse plaide ainsi pour une approche relationnelle entre "local" et "global" au sein des scènes musicales. mots-clés : local, global, scène musicale, rap, Dirty South, Sénégal
description: Rap Galsen vs Dirty South : revisiting the local/global divide through the lens of differentiation processes within a musical scene In the wake of the 30th anniversary of « rap Galsen », this article explores the tensions between different generations of rappers by zooming in on material ostentation. This focus enables us to reveal the processes of differentiation at work in the definition of "local" rap in Senegal and to revisit its boundaries with the "global". I will show that practices of material ostentation in rap in Senegal go hand-and-hand with transformations in the musical genre of rap on a global scale. However, rather than trying to "imitate Americans", artists of the "new generation" first and foremost position themselves within a particular musical scene. I therefore call for a relational approach to the "local" and the "global" within musical scenes. keywords : local, global, music scene, rap, Dirty South, Senegal

description: Au lendemain de la révolution tunisienne, le rap s'est imposé comme un symbole du changement de régime, et il est aujourd'hui devenu une des musiques les plus écoutées. Cependant, l'émergence d'un « rap tunisien » est le résultat d'un processus d'appropriation qui a débuté bien avant le changement de régime en 2011. Cet article analyse les formes d'appropriation du rap opérées par les artistes tunisiens, en distinguant d'une part les supports de sa circulation et son ancrage dans le pays, et d'autre part, les différentes formes d'hybridation qu'il y a générées. En partant d'observations et de récits de vie de rappeurs tunisiens, il met en évidence deux genres d'appropriation du rap selon des logiques locales : « le rap en mobilité » et « la culture tunisienne samplée ». Mots-clés : Rap tunisien, mobilité, hybridation, imitation, globalisation, local, révolution.
description: The hybridization of rap by Tunisian artists : local and international logics In the aftermath of the Tunisian revolution, rap has become a symbol for the change of regime, and one of the most popular music genres in the country. However, the emergence of "Tunisian rap" is the result of a process of appropriation that began long before regime change. This article analyzes the forms of hybridization of rap operated by Tunisian artists, distinguishing, on the one hand, how it has circulated and spread in this country and, on the other hand, the different forms of hybridization that it has generated. Based on observations and life histories of Tunisian rappers, the article highlights two forms of appropriation of rap : "rap in mobility" and "sampled Tunisian culture". keywords : Tunisian rap, transit, hybridization, imitation, globalization, local, revolution.

description: Pattern formation is ubiquitous in nature from morphogenesis and cloud formation to galaxy filamentation. More often than not, patterns arise in a medium driven far from equilibrium due to the interplay of dynamical instability and nonlinear wave mixing. We report, based on momentum and real space pattern recognition, formation of density patterns with two- (D$_2$), four- (D$_4$) and six-fold (D$_6$) symmetries in Bose-Einstein condensates (BECs) with atomic interactions driven at two frequencies. The symmetry of the pattern is controlled by the ratio of the frequencies. The D$_6$ density waves, in particular, arise from a resonant wave mixing process that coherently correlates and enhances the excitations that respect the symmetry.
