Globalization is perhaps only another name to replace the lacking one for what is
happening to (with) us humans in the name of techno-bureaucratic, commercial,
violent, amusing, consumerist process of creating a so-called global society of
knowledge and skills. "Globalization offers both a theory of everything and an
explanation of nothing" - suggests J. Annesley in Fictions of Globalization (2006).
However, daily deaths of children as a result of hunger, disease and malnutrition on a
massive scale in Africa, and elsewhere, is not fiction....
In this paper we prove the global existence and uniqueness (regularity) of strong solutions to the three-dimensional viscous primitive equations, which model large scale ocean and atmosphere dynamics. 1. Introduction Large scale dynamics of oceans and atmosphere is governed by the primitive equations which are derived from the Navier-Stokes equations, with rotation, coupled to thermodynamics and salinity diﬀusion-transport equations, which account for the buoyancy forces and stratiﬁcation eﬀects under the Boussinesq approximation. ...
Limited success in scaling-up ITN coverage reflects the inadequately acknowledged economic barriers that prevent the destitute sick from accessing critical preventive technologies. Despite proven efficacy and what are considered "reasonable costs," the 2003 RBM report reveals disappointing levels of ITN coverage. In 28 African countries surveyed, only 1.3% (range, 0.2–4.9%) of households owned at least one ITN, and
Beyond TMT, we find no systematic increase in the importance of industry effects.
Instead, we observe that the ratio of industry to country effects follows a U-shape pattern
from the mid-1980s to the late-1990s, a cyclical pattern whereby global industry effects
become temporarily more important in relative and absolute terms around periods of stock
market distress, such as October 1987 and March 2000. We view this cyclical pattern as
further evidence that the recent increase in industry effects is temporary....
These features are enabled by the fact that Spanner as-
signs globally-meaningful commit timestamps to trans-
actions, even though transactions may be distributed.
The timestamps reﬂect serialization order. In addition,
the serialization order satisﬁes external consistency (or
equivalently, linearizability ): if a transaction T1
commits before another transaction T2 starts, then T1’s
commit timestamp is smaller than T2’s. Spanner is the
ﬁrst system to provide such guarantees at global scale.
Extensive knowledge bases of entailment rules between predicates are crucial for applied semantic inference. In this paper we propose an algorithm that utilizes transitivity constraints to learn a globally-optimal set of entailment rules for typed predicates. We model the task as a graph learning problem and suggest methods that scale the algorithm to larger graphs. We apply the algorithm over a large data set of extracted predicate instances, from which a resource of typed entailment rules has been recently released (Schoenmackers et al., 2010). ...
Text categorization is a crucial and wellproven method for organizing the collection of large scale documents. In this paper, we propose a hierarchical multi-class text categorization method with global margin maximization. We not only maximize the margins among leaf categories, but also maximize the margins among their ancestors. Experiments show that the performance of our algorithm is competitive with the recently proposed hierarchical multi-class classiﬁcation algorithms.
Chapter 12 - Entering foreign markets. The objectives of this chapter: Explain the three basic decisions that firms contemplating foreign expansion must make: which markets to enter, when to enter those markets, and on what scale. Compare and contrast the different modes that firms use to enter foreign markets. Identify the factors that influence a firm's choice of entry mode. Recognize the pros and cons of acquisitions versus greenfield ventures as an entry strategy.
Fewer ﬁsh exacerbate the declines in walrus and seal
populations. Overall, there is less food available for the Yupik Eskimos of the
Arctic who rely on all of these species.
Global climate change is thus a signiﬁcant addition to the spectrum of envi-
ronmental health hazards faced by humankind. The global scale makes for unfa-
miliarity—although most of its health impacts comprise increases (or decreases)
in familiar effects of climatic variation on human biology and health.

Generation Change in Cellular Systems
In Japan, mobile communications systems based on cellular technology have evolved, as illustrated in Figure 1.1. The ﬁrst-generation analog car phones were ﬁrst introduced in 1979, followed by the commercialization of the second-generation digital phones in 1993. Mobile phone subscribers have rapidly increased in number since then, owing to the liberation of terminal sales and continuous price reductions. In March 2000, the number of mobile phone subscribers outnumbered those of ﬁxed telephones.
Judicious treatment of environmental questions and challenges requires an integrated, crossdisciplinary
approach. Whether working at a local, national, regional, or global scale, the knowledge
and expertise resident in a variety of subject areas comes to bear on all questions of
sustainable development. Soil scientists now collaborate with colleagues in many Þelds, and a

Biomedical research has entered a new era of characterizing a disease or a protein on a global scale. In the post-genomic era, Proteomics now plays an increasingly important role in dissecting molecular functions of proteins and discovering biomarkers in human diseases. Mass spectrometry, two-dimensional gel electrophoresis, and high-density antibody and protein arrays are some of the most commonly used methods in the Proteomics field.
Evidence grows daily of the rapid changes in climate due to human activities and
their impact on plants and animals. Plant function is inextricably linked to climate
and atmospheric carbon dioxide concentration. On the shortest and smallest scales
the climate affects the plant’s immediate environment and thus directly inﬂuences
physiological processes. On longer and larger time and space scales climate inﬂu-
ences species distribution and community composition and determines what crops
can be viably produced in managed agricultural, horticultural and forestry ecosys-

The miniaturization and performance improvement in semiconductor devices and
integrated circuits (ICs) are expected to continue through leveraging of nanotechnologies and
nanomaterials. This evolution should accelerate the System-on-a-Chip (SoC) trend, i.e., singlechip
integration of multifunctional, mixed-signal electronic components, toward realizing
embedded nanoelectronic systems.
Estimating the transport and fate of chemicals released into the environment is an
interesting and challenging task. The global environment is large on the chemical
transport and fate scale. This text applies the mathematics of diffusion, turbulent
diffusion, and dispersion to the atmosphere, lakes, rivers, groundwater, and oceans, as
well as transport between these media. The book follows a new educational paradigm
of textbooks, in that it is based on examples and case studies.
