Resumen

This paper is based on a sample of 104 subsidiaries of multinational corporations (MNCs) operating in Brazil. It investigates the mechanisms of knowledge transfer in marketing and their relationship to the strategic positioning of the subsidiaries (i.e. global integration and local responsiveness). A positive correlation between the level of global integration and the intensity of knowledge transfer was statistically confirmed and the main mechanisms of knowledge transfer were also revealed. Some widely accepted theories about knowledge transfer in MNCs were empirically confirmed. Finally, this study provided the opportunity to develop several specific insights about knowledge transfer in marketing in the Brazilian context.

Resumen

The Meta-analysis has increasingly been used to synthesize the ecosystem services literature, with some testing of the use of such analyses to transfer benefits. These are typically based on local primary studies. However, meta-analyses associated with ecosystem services are a potentially powerful tool for transferring benefits, especially for environmental assets for which no primary studies are available. In this study we use the Ecosystem Service Valuation Database (ESVD), which brings together 1350 value estimates from more than 320 studies around the world, to estimate meta-regression functions for Provisioning, Regulating and maintenance, and Cultural ecosystem services across 12 biomes. We tested the reliability of these meta-regression functions and found that even using variables with high explanatory power, transfer errors could still be large. We show that meta-analytic transfer performs better than simple value transfer and, in addition, that local meta-analytical transfer (i.e., based on local explanatory variable values) provides more reliable estimates than global meta-analytical transfer (i.e., based on mean global explanatory variable values). Thus, we conclude that when taking into account the characteristics of the study area under analysis, including explanatory variables such as income, population density, and protection status, we can determine the value of ecosystem services with greater accuracy.

Resumen

Purpose The dominant paradigm in international branding research treats perceived brand globalness (PBG) and localness (PBL) as attributes algebraically participating in brand assessment and disregards the perception of brands as humanlike entities actively embedded in consumers’ social environments. Challenging this view and drawing from stereotype theory, the purpose of this paper is to suggest that PBG/PBL trigger the categorization of products under the superordinate mental categories of global/local brands which carry distinct stereotypical content. Such content transfers to every individual product for which category membership is established and shapes brand responses. Design/methodology/approach One experimental study (Study1, n=134) tests the process of global/local brand stereotype formation, identification and content transfer. Subsequently, two consumer surveys test the impact of brand stereotypes on brand approach/avoidance tendencies (Study2, n=328) and consumer–brand relationships (Study3, n=273). Data were analyzed with experimental techniques and structural equation modeling. Findings The findings suggest that upon categorization under the global or local brand class, individual brands are charged with the stereotypical content of the class. Global brands are predominantly stereotyped as competent while local brands are predominantly stereotyped as warm. Localness-induced warmth has uniformly positive effects, whereas globalness-induced competence acts as a double-edged sword which can both help and harm the brand. Originality/value This research contributes by proposing a novel conceptualization of global and local brands as groups of intentional marketplace agents stereotyped along their intentions and abilities, empirically establishing the process through which individual brands are assigned stereotypical judgments and demonstrating how these judgments impact critical brand outcomes and consumer–brand relationships.

Resumen

In the current work, globally based on Koopmans’ approximation, local electron transport characteristics of dihydroxybenzenes have been examined using the density functional theory for understanding their antioxidant activity. Our experimental and theoretical studies show that hydroquinone has better antioxidant activities when compared to resorcinol and catechol. To identify the antioxidant sites for each dihydroxybenzene molecule, an average analytical Fukui analysis was used. The typical Fukui analytical results demonstrate that dihydroxybenzene oxygen atoms serve as antioxidant sites. The experimental and theoretical results are in good agreement with each other; therefore, our results are reliable.

Resumen

In this paper a general transfer matrix method (TMM) for rotors containing global and local coupler offset was derived. Rotor response due to imbalances and offsets are then studied via the developed method. The studies showed both global and local offsets played as an external excitation that is a combined effect of all the elements behind the offset. Differences between global offset and local offset were compared and the results showed both types basically retain the same mode patterns but different jumps at the offset. The global offset, yet, imposed more significant dynamic effects since all the offsets accumulate thereafter. The whirling orbits in front and behind the offset were illustrated as well. The results, as expected, showed global offset appeared much larger radii especially after offset. The rotor's whirling orientation reversed, as rotation fell within a certain range and this feature was not changed by offsets. The TMM proposed by this study can be well applied to multiple global and local offsets.

Resumen

How local industrial clusters realize industrial upgrading in the development process of embedded global value chain is the central topic. To explore how industrial clusters achieve the enhancement of their innovation capability and value chains when they are embedded in the global value chain, from the perspective of knowledge transfer, three fuzzy game models of knowledge transfer paths were constructed, and the model of the realization mechanism of knowledge transfer and its stability condition was analyzed, which make clear the path of cluster growth under different embedding modes. Results show that the knowledge transformation ability of local industrial clusters is the determining factor that the knowledge transfer can smoothly achieve and become stable. The conclusion also shows the feasibility of the cross-sectional growth of industrial clusters by actively embedding the global value chain and acquiring external knowledge transfer if the industrial clusters want to enhance their technology accumulation, their innovation ability, and their position in the global value chain.

Resumen

Computational fluid dynamics (CFD) provides a flexible tool for investigation of separation processes within membrane hollow fiber modules. By enabling a three-dimensional and time dependent description of the corresponding transport phenomena, very detailed information about mass transfer or geometrical influences can be provided. The high level of detail comes with high computational costs, especially since species transport simulations must discretize and resolve steep gradients in the concentration polarization layer at the membrane. In contrast, flow simulations are not required to resolve these gradients. Hence, there is a large gap in the scale and complexity of computationally feasible geometries when comparing flow and species transport simulations. A method, which tries to cover the mentioned gap, is presented in the present article. It allows upscaling of the findings of species transport simulations, conducted for reduced geometries, on the geometrical scales of flow simulations. Consequently, total transmembrane transport of complete modules can be numerically predicted. The upscaling method does not require any empirical correlation to incorporate geometrical characteristics but solely depends on results acquired by CFD flow simulations. In the scope of this research, the proposed method is explained, conducted, and validated. This is done by the example of CO2 removal in a prototype hollow fiber membrane oxygenator.

Resumen

Radial basis function (RBF) interpolation algorithm for data transfer on coupling interface is derived from the shape function, and the global D-Lanczos (GLDL) method is introduced to solve the displacement transfer matrix. In order to improve the computational efficiency, a local compactly supported RBF (CSRBF) interpolation algorithm is proposed based on the partition acceleration treatment, and a comparison of the algorithmic complexity is made among the global Multi-Quadrics (MQ), CSRBF and the local CSRBF. Numerical test shows the significant shortening of CPU time by using the local CSRBF interpolation algorithm.

Resumen

Abstract Global technology transfers reshape agriculture with profound influences on everyday life. Substantial research has documented broader constraints that influence technology transfer among farmers, yet existing theories give us a narrow view into how wider dynamics manifest in everyday life. Using tractor farming in Ethiopia as a case study with ethnographic and historical data, we contribute an account of the everyday social and ecological interactions that shape agricultural technology transfer as well as the wider historical context in which these practices play out. Historically, we find an uneven transition that faltered repeatedly over 50 years. Ethnographically, we identify three types of interplays between actors and the local ecology that shaped the ways that faltering technology transfer actually plays out on the ground: (1) socio-ecological frictions; (2) communicative frictions; and (3) status-based frictions. This study contributes a humanistic account of how farmers and local technology providers experience technology transfers.

Resumen

A mathematical model considering the inter-phase mass transfer both in the down-comer and the riser of an external-loop airlift reactor was established in this paper. The calculated global volumetric mass transfer coefficient based on the assumption of continuous stirred tank reactor (CSTR) was different from the local volumetric mass transfer coefficients by the newly proposed mathematical model and the difference was discussed. The effects of mass transfer in the down-comer, the hydrodynamic pressure and the experimental time on the mass transfer coefficient measurement model have been studied in detail. And it was also proved that only the global volumetric mass transfer coefficient, but not the local volumetric mass coefficient, can be obtained from a time-concentration curve in the external-loop airlift reactor.

Resumen

Traditional iris recognition systems transfer iris images to polar coordinates, normalize the images and achieve rotation invariance by rotating the feature vector. In order to decrease the complexity of the typical iris recognition method, we propose a new method of iris recognition based on global and local model that are extracted from preprocessed iris image without normalizing. Firstly, we applied a bank of no-tensor product wavelet filters to extract the global features of the iris. Secondly, we used a SIFT method to extract the local features points of the selected regions. Finally, we tested the similarity distances of local and global features with different weights. Experimental results show that the proposed method in this paper has the recognition accuracy of 99.5% when the equal error rate is 0.94%. Without normalizing the iris images, the proposed approach can obtain very good recognition performance.

Resumen

Global companies are pressed by the need to simultaneously manage globally since they consider the whole world as their own market, and locally, because the global market consists of various different and weakly connected market segments. The need to be global and local at the same time presents, perhaps the most important challenge for management of global companies in 21st century. Searching this balance presents also an important challenge for human resource management (HRM), regarding the ways of accomplishing it. HRM is expected to contribute to achievement of global competitive advantage worldwide efficiency, local responsiveness, as well as transfer of learning within global organizations. The transfer of learning gains on its importance as many authors see it as the main motive of establishing global companies. However, regardless of recognized significance of organizational learning for global companies, international HRM literature simply lacks studies related to transfer of learning, recommendations about how to develop this organizational ability, how to improve it and measure, and how to provide permanency of the learning process. Therefore, the aim of this paper is through reviewing the relevant literature, to shed light on different aspects of the responsiveness-integration paradigm and its implications on the transfer of learning in global companies.

Resumen

Global and local corrosion techniques were used to study the corrosion behavior of weld joints of a high-strength low-alloy steel (LNE500) typically used in the automotive industry in Brazil. The welded joints were prepared by gas metal arc welding. Two welding transfer modes were used to obtain different heat inputs: pulsed (PUL) and cold metal transfer (CMT). Local and global corrosion analysis techniques presented complementary information. While the local in situ analysis (scanning vibrating electrode technique) revealed the weld metal (WM) as the region where corrosion started, conventional electrochemical techniques (potentiodynamic polarization [PP] and electrochemical impedance spectroscopy [EIS]) revealed a higher corrosion rate in the coarse-grained heat affected zone, which was preferentially corroded. A superior corrosion resistance of the WM obtained using CMT over the PUL transfer mode was revealed by EIS and PP. In addition, the results from CMT and PUL samples show that the austenite grain size affects the propagation of the corrosion process. The results are discussed based on microstructural and compositional aspects of the different regions that characterize the welded joints.

Resumen

The goal of the experiment is to transfer a local model to a global model for the prediction of a new parameter. Station de Haute Belgique (SHB) has developed an extensive spectral database to determine 10 parameters of whole plant maize silage samples. Pioneer has determined the Tilley and Terry digestibility (T&T) on a smaller set of samples. The analysis of the Mahalanobis distances between the two sets shows that Pioneer's set has a much smaller variation than SHB's set. Pioneer's set can be predicted by SHB's calibrations, but SHB's database cannot be predicted by Pioneer's calibration. The 10 parameters predicted on Pioneer's set are used to estimate the Tilley and Terry digestibility coefficient through a PLS model. The same model is then used to predict T&T on the large SHB set. The later predicted values are reported as references on SHB's set and a global T&T equation is developed after an adequate sample selection. The procedure shows that the new equation, applied on independent sets, is more accurate and more robust than the local one.

Resumen

Even photosynthesis—the most basic natural phenomenon underlying life on Earth—involves the nontrivial processing of excitations at the pico- and femtosecond scales during light-harvesting. The desire to understand such natural phenomena, as well as interpret the output from ultrafast experimental probes, creates an urgent need for accurate quantitative theories of open quantum systems. However it is unclear how best to generalize the well-established assumptions of an isolated system, particularly under nonequilibrium conditions. Here we compare two popular approaches: a description in terms of a direct product of the states of each individual system (i.e., alocalapproach) versus the use of new states resulting from diagonalizing the whole Hamiltonian (i.e., aglobalapproach). The main difference lies in finding suitable operators to derive the Lindbladian and hence the master equation. We show that their equivalence fails when the system is open, in particular under the experimentally ubiquitous condition of a temperature gradient. By solving for the steady state populations and calculating the heat flux as a test observable, we uncover stark differences between the formulations. This divergence highlights the need to establish rigorous ranges of applicability for such methods in modeling nanoscale transfer phenomena—including during the light-harvesting process in photosynthesis.

Resumen

In Korea, demands for economic and social democratization increasedafter 2000, as the country dealt with economic recession after the 1997 Asianfinancial crisis and with other problems resulting from mismanaged domesticpolicies. In response, the Korean state carried out unprecedented reform of thepublic sector to address these problems by streamlining state capacity. Theprimary objectives of this article are to understand Korean public sector reformtogether with its domestic political factors from a policy transfer perspective,and to suggest an alternate model for the reforms. The reforms, which took placeduring the Kim Dae-Jung and the Roh Mu-Hyun administrations, were consolidatedthrough proactive policy transfer by politico-bureaucratic decisions inorder to establish a new statecraft despite the global diffusion of policy trends.Investigation of its domestic political circumstances and historical contextreveals that the reforms were not direct emulations of global norms, but ratheran attempt to use a mixture of models to raise the quality of government.

Resumen

Communication overhead remains a significant challenge in federated learning due to frequent global model updates. Essentially, the update of the global model can be viewed as knowledge transfer. We aim to transfer more knowledge through a compact model while reducing communication overhead. In our study, we introduce a federated learning framework where clients pre-train large models locally and the server initializes a compact model to communicate. This compact model should be light in size but still have enough knowledge to refine the global model effectively. We facilitate the knowledge transfer from local to global models based on pre-training outcomes. Our experiments show that our approach significantly reduce communication overhead without sacrificing accuracy.

Resumen

Global and local features are essential for visual-similarity texture perception. Therefore, understanding how people allocate their visual attention when viewing textures with global or local similarity is important. In this work, we investigate the influences of global and local features of a texture on eye-movement patterns and analyze the relationship between eye-movement patterns and visual-similarity selection. First, we synthesized textures by separately controlling global and local textural features through the primitive, grain, and point configuration (PGPC) texture model, a mathematical morphology-based texture model. Second, we conducted an experiment to acquire eye-movement data where participants identified the texture that was highly similar to the standard texture. Experiment data were obtained through an eye-tracker from 60 participants. The collected eye-tracking data were analyzed in terms of three metrics, including total fixation duration in each region of interest (ROI), fixation-point variance in each ROI, and fixation-transfer counts between different ROIs. Analysis results indicated the following. (1) The global and local features of a texture influenced eye-movement patterns. In particular, the texture image that was globally similar to the standard texture contained dispersed fixation points. By contrast, the texture image that was locally similar to the standard texture contained concentrated fixation points. The domination of global and local features influenced the viewers’ similarity choice. (2) The final visual-similarity selection was related to the fixation-transfer count between different ROIs, but not to the fixation time in each ROI. This research also extends the applicability of the mathematical morphology-based texture model to human visual perception.

Resumen

Loss of production due to local water scarcity, i.e., Local Water Scarcity Risk (LWSR), is transferred downstream through international supply chains to distant economies, causing potential economic losses to countries and sectors that do not directly experience actual water scarcity, which is defined as Virtual Water Scarcity Risk (VWSR). Much research has focused on assessing VWSR and characterizing the structure of VWSR transfer networks, without explaining the formation and dynamics of VWSR transfer network patterns. In this study, the global VWSR transfer networks for 2001–2016 are then constructed based on a multi-regional input-output model and complex network theory. The determinants influencing the formation of VWSR transfer networks are further explored using the time-exponential random graph model. The results demonstrate that: (1) The VWSR transfer networks exhibit a distinctly small-world and heterogeneous nature; (2) Asia and Europe are the main targets of VWSR transfers, and Asia is also the main source of risks; (3) China and the USA play a leading role on the import side of VWSR, and India is the largest exporter of VWSR; (4) The evolution of VWSR transfer networks is significantly influenced by transitivity and stability. Countries located on the same continent, sharing geographical borders and having a higher level of economic development, have a facilitating effect on the formation and evolution of VWSR transfer networks. Countries with a higher share of merchandise trade are more inclined to receive VWSR inflows, while the urbanization rate has a restraining effect on VWSR outflows. The study provides a network-based insight that explores the structural evolution of VWSR transfer networks and the determinants of their formation, informing policy makers in developing strategies to mitigate the cascading spread of VWSR.

Resumen

The evolution of the dislocation density during Czochralski growth is computed by the combination of global thermal calculations and local computation of the stress and dislocation density in the crystal. The global simulation was performed using the open-source software Elmer (version 8.4) and the local simulation with the open-source software MACPLAS (version of 23.1.2023). Interpolation both in space and time was used to transfer the boundary conditions from the global simulations to the local model, which uses a different mesh discretization and a considerably smaller time step. We applied this approach to the Czochralski growth of a high-purity Ge crystal. The heater power change predicted by the global model as well as the final dislocation density distribution in the crystal simulated by the local model are correlated to the experimental results.

Resumen

Living systems such as gene regulatory networks and neuronal networks have been supposed to work close to dynamical criticality, where their information-processing ability is optimal at the whole-system level. We investigate how this global information-processing optimality is related to the local information transfer at each individual-unit level. In particular, we introduce an internal adjustment process of the local information transfer and examine whether the former can emerge from the latter. We propose an adaptive random Boolean network model in which each unit rewires its incoming arcs from other units to balance stability of its information processing based on the measurement of the local information transfer pattern. First, we show numerically that random Boolean networks can self-organize toward near dynamical criticality in our model. Second, the proposed model is analyzed by a mean-field theory. We recognize that the rewiring rule has a bootstrapping feature. The stationary indegree distribution is calculated semi-analytically and is shown to be close to dynamical criticality in a broad range of model parameter values.

Resumen

The influence of a honeycomb facing on the heat transfer of a stepped labyrinth seal with geometry typical for modern jet engines was investigated. Heat transfer measurements were obtained for both a smooth stator and a stator lined with a honeycomb structure. In addition, an LDV system was used with the scaled up geometry to obtain a high local resolution of the velocity distribution in the seal. The experiments covered a wide range of pressure ratios and gap widths, typical for engine operating conditions. Local heat transfer coefficients were calculated from the measured wall and gas temperatures using a finite element code. By averaging the local values, mean heat transfer coefficients were determined and correlations for the global Nusselt numbers were derived for the stator and the rotor. The LDV results showed strong geometrical effects of the honeycomb structure on the development of the flow fields for the honeycomb seal. The distribution of the local heat transfer coefficients are compatible with the flow features identified by the LDV results and reveal a significantly reduced heat transfer with the honeycomb facing compared to the smooth facing.

Resumen

Stability control of the welding process is necessary to guarantee weld quality. In this study, a sensing method that collects both global and local arc information was proposed to conveniently monitor metal transfer stability during gas tungsten arc welding. This sensing method was also used to monitor the stability of the weld surface height by sensing the change in global arc length. The stability factor (fmt) was calculated to quantify the metal transfer stability. The characteristic signal (U*), which represents the average global arc voltage in the presence of a liquid bridge, was extracted to characterize the change in arc length by decoupling the dynamic interference signal of metal transfer. Both a fuzzy controller and a proportional integral derivative controller were designed to control the metal transfer stability and the weld surface height. The preliminary control experiments proved the effectiveness and potential of the proposed sensing and control strategies.

Resumen

Abstract This study presents numerical simulations of the convective heat transfer on wavy micro-channels to investigate heat transfer enhancement in these systems. The goal is to extend the analysis of our previous work [1, 2], by proposing a methodology based on local and global energy balances in the device instead of the commonly used Nusselt number. The analysis is performed on a single-wave baseline micro-channel model that is exposed to a heat influx. The governing equations for an incompressible laminar flow and conjugate heat transfer are first built, and then solved, for representative models, under several operating conditions, by the finite element technique. From computed velocity, pressure and temperature fields, local and global energy balances based on cross-section-averaged velocities and temperatures enable calculating the heat rate at each section. Results from this study show that this so-called averaged energy-balance methodology enables an accurate assessment of the channel performance.

Resumen

Thanks to the transfer of technology from Brazil, Angola is entering the sucroalcooleiro sector with multiple aims. These include creating jobs in rural areas, diversifying the energy mix and boosting exports. Angola is one of the countries that has envisioned international technology transfer as a strategy to increase participation in the global market, while decreasing its dependence on sugar imports. While the production of ethanol and sugar can bring about some benefits, technology transfer in this area is not without risks. It needs to be carefully crafted and executed, especially in accordance with the principles of sustainable development, which is by the government plan of Angola to include, rather than exclude, the rural poor. This study shows that stakeholders presented different opinions in relation to Biocom and sustainable development. The main reason is linked to the distinction between global, national and local levels. On the global level, ITT and Biocom are seen as alternative renewable sources of energy (ethanol) to fossil fuels, on the local level there is a concern with the socio-environmental issues which local communities might face, indeed ITT and Biocom are perceived as a risk in case locals lose their lands and do not receive compensation. On the national level, while there is the expectancy of employment, infrastructure development and attraction of investments in the country, there is a lack of trust in governance by Angolan civil society; which argues that Angolan government and enterprises do not encourage public participation nor allows it to happen. Technology transfer is perceived as a business and geopolitical strategy driven by private and state interests, undermining environmental and social costs. On the other hand technology transfer is seen as a key to foster economic opportunities towards sustainable development.
