Postponement and the wealth of nations

In this paper, Fair Value Chain Creation (FVC2;), as an approach that applies and extends principles of Fair Trade to exports from developed countries to the less developed countries, is being introduced. It awards a Fair Value label to goods which undergo further value adding in the host market. FVC2; attempts to utilize a label pointing at made for rather than made in by emblematizing the degree of Fair Value involved. Building on logistics and manufacturing postponement allows FVC2; to balance value chains in such a way that both stakes (North - South; developed countries - developing countries; country of origin - host market) are going to profit. Developing countries can increase their share in value chains originating from Northern countries. In turn, this enables those developed countries and corresponding manufacturers to level their resources. While postponing none-core activities to the developing countries and the respective host markets, manufacturers can focus even more on core processes. In fact, FVC2; mostly employs humans instead of machines. It makes labor a promoted option. Based on free-market mechanisms, like opportunity costs and the production possibilities frontier, the authors prove FVC2; being an attempt in the market and on the structure of global value chains. Fair Value Chain Creation is driven by enhanced global logistics performance. Thus, and in contrast to Fair Trade, FVC2; requires no price premium being paid by the consumer and therefore no stringent inspection of its application. Nonetheless, every labeling initiative requires an authority to prevent malpractice. The authors show, before such an initiative can be put into practice, that it is particularly evident to define the developing gap enabling to specify the potential and spectrum of FVC2;. This gap arises from globalization and enhanced logistics performance (foremost postponement). --Fair Trade,Fair Value Chain,Fair Value Creation,Postponement,Wealth of Nations

Seismicity at the Rwenzori Mountains, East African Rift: earthquake distribution, magnitudes and source mechanisms

We have analysed the microseismic activity within the Rwenzori Mountains area in the western branch of the East African Rift. Seismogram recordings from a temporary array of up to 27 stations reveal approximately 800 events per month with local magnitudes ranging from –0.5 to 5.1. The earthquake distribution is highly heterogeneous. The majority of located events lie within faults zones to the East and West of the Rwenzoris with the highest seismic activity observed in the northeastern area, where the mountains are in contact with the rift shoulders. The hypocentral depth distribution exhibits a pronounced peak of seismic energy release at 15 km depth. The maximum extent of seismicity ranges from 20 to 32 km and correlates well with Moho depths that were derived from teleseismic receiver functions. We observe two general features: (i) beneath the rift shoulders seismicity extends from the surface down to ca. 30 km depth; (ii) beneath the rift valley seismicity is confined to depths greater than 10 km. From the observations there is no indication for a crustal root beneath the Rwenzori Mountains. The magnitude frequency distribution reveals a b-value of 1.1, which is consistent with the hypothesis that part of the seismicity is caused by magmatic processes within the crust. Fault plane solutions of 304 events were derived from P-polarities and SV/P amplitude ratios. More than 70 % of the source mechanisms exhibit pure or predominantly normal faulting. T-axis trends are highly uniform and oriented WNW-ESE, which is perpendicular to the rift axis and in good agreement with kinematic rift models. At the northernmost part of the region we observe a rotation of the T-axis trends to NEN-SWS, which may be indicative of a local perturbation of the regional stress field

A Pose-Sensitive Embedding for Person Re-Identification with Expanded Cross Neighborhood Re-Ranking

Person re identification is a challenging retrieval task that requires matching a person's acquired image across non overlapping camera views. In this paper we propose an effective approach that incorporates both the fine and coarse pose information of the person to learn a discriminative embedding. In contrast to the recent direction of explicitly modeling body parts or correcting for misalignment based on these, we show that a rather straightforward inclusion of acquired camera view and/or the detected joint locations into a convolutional neural network helps to learn a very effective representation. To increase retrieval performance, re-ranking techniques based on computed distances have recently gained much attention. We propose a new unsupervised and automatic re-ranking framework that achieves state-of-the-art re-ranking performance. We show that in contrast to the current state-of-the-art re-ranking methods our approach does not require to compute new rank lists for each image pair (e.g., based on reciprocal neighbors) and performs well by using simple direct rank list based comparison or even by just using the already computed euclidean distances between the images. We show that both our learned representation and our re-ranking method achieve state-of-the-art performance on a number of challenging surveillance image and video datasets.

Development of International Educational Systems by Competence Networking based on Project Management

AbstractThe globalization demands new kinds of concepts and models to ensure the provision of skilled labor by international educational systems based on advanced competence networking. The success depends on the professional use of the latest project management theory, methodology, and practice. Multinational multi-projects fail and are aborted. A reason for that could be the deficiency of project readiness. The project management approach should be integrated into other management subsystems such as information, knowledge, competence, network management etc. One of the most important challenges is to ensure the communication and information transfer for competence balancing and sharing. A successful and efficient cooperation is only possible under equivalent partners. It creates the necessary trust. Beginning with the presentation of the need for cooperation and the exchange of knowledge for global and fair growth, the relationship between education, competence development and applied project management will be explained for educational transfer systems. Subsequently, the application of the approach will be illustrated by the planning, designing, implementing, and further developing of a large-scale Sino-German cooperation in higher education. The success of the project and the sustainability will be guaranteed. The roll-out to other network partners on a national and international scale is in progress

Matching Parton Showers and Matrix Elements

We compare different procedures for combining fixed-order tree-level matrix element generators with parton showers. We use the case of W-production at the Tevatron and the LHC to compare different implementations of the so-called CKKW scheme and one based on the so-called MLM scheme using different matrix element generators and different parton cascades. We find that although similar results are obtained in all cases, there are important differences.Comment: Proceedings of the "HERA and the LHC" workshop, CERN/DESY 2004/200

Calcium decreases cell wall swelling in sweet cherry fruit

Swelling of epidermal cell walls decreases cell-to-cell adhesion and increases cracking susceptibility in sweet cherry. Ca is suggested to decrease cracking susceptibility by crosslinking of cell wall components and, possibly, by decreasing swelling. The objective is to test this hypothesis. The effect of Ca on swelling of anticlinal epidermal cell walls was quantified microscopically in vivo using excised skin sections and in vitro using extracted cell walls. After removal of turgor, cell wall thickness increased. Incubation in CaCl2 decreased cell wall thickness up to 3 mM CaCl2. At higher concentrations thickness remained constant. Decreased cell wall swelling in vivo also occurred with other salts of divalent and trivalent cations, but not with those of monovalent cations. Decreased swelling was due to the Ca cation, the anions had no effect. Ca also decreased swelling of cell walls that were already swollen. CaCl2 also decreased swelling of extracted cell walls in vitro. There was no effect on swelling pressure. The effect on swelling increased as the CaCl2 concentration increased. Chlorides of divalent and trivalent cations, but not those of monovalent cations decreased swelling in vitro. The decrease in swelling among the divalent cations was linearly related to the radius of the cation. The results indicate that Ca decreases cracking susceptibility by decreasing swelling

Global irrigation water demand: Variability and uncertainties arising from agricultural and climate data sets

Agricultural water use accounts for around 70% of the total water that is withdrawn from surface water and groundwater. We use a new, gridded, global-scale water balance model to estimate interannual variability in global irrigation water demand arising from climate data sets and uncertainties arising from agricultural and climate data sets. We used contemporary maps of irrigation and crop distribution, and so do not account for variability or trends in irrigation area or cropping. We used two different global maps of irrigation and two different reconstructions of daily weather 1963–2002. Simulated global irrigation water demand varied by ∼30%, depending on irrigation map or weather data. The combined effect of irrigation map and weather data generated a global irrigation water use range of 2200 to 3800 km3 a−1. Weather driven variability in global irrigation was generally less than ±300 km3 a−1, globally (\u3c∼10%), but could be as large as ±70% at the national scale
