Finnair’s “New Silk Road” in the New Millennium: An Analysis of the Construction of Asia and of the Company
During the past century, an increasingly diverse world provided us with opportunities for intercultural communication; especially the growth of commerce at all levels from domestic to international has made the combination of the theories of intercultural communication and international business necessary.
As one of the main beneficiaries in international business in recent years, companies in airline industries have developed their international market. For instance, Finnair has developed its Asian strategy which responds to the increasing market demand for flights from Europe to Asia in the new millennium. Therefore, the company manages marketing communication in a global environment and becomes a suitable case for studying the theories of intercultural communication in the context of international marketing.
Finnair implemented a large number of international advertisements to promote its Asian routes, where Asia has been constructed as a number of exotic destinations. Meanwhile, the company itself as a provider of these destinations has also been constructed contrastively. Thus, this thesis aims at research how Finnair constructs Asia and the company itself in the new millennium, and how these constructions compare with the theories of intercultural communication.
This research applied the theories of international marketing, intercultural communication and culture. In order to analyze the collected corpora as Finnair’s international advertisements and its annual reports in the new millennium, the methods of content analysis and discourse analysis have been used in this research.
As a result, Finnair has purposefully applied the essentialist approach to intercultural communication and constructed Asia as an exotic “Other” due to the company’s market orientation. Meanwhile, Finnair has also constructed the company itself two identities based on the same approach: as an international airline provider between Europe and Asia, as well as a part of Finnish society.
The combination of intercultural communication and international marketing theories, together with the combination of the methods of content analysis and discourse analysis ensure the originality of this paper.Siirretty Doriast
Thermal properties of and meson
We computed the pole masses and decay constants of and meson at
finite temperature in the framework of Dyson-Schwinger equations and
Bethe-Salpeter equations approach. Below transition temperature, pion pole mass
increases monotonously, while meson seems to be temperature independent.
Above transition temperature, pion mass approaches the free field limit,
whereas meson is about twice as large as that limit. Pion and the
longitudinal projection of meson decay constants have similar behaviour
as the order parameter of chiral symmetry, whereas the transverse projection of
meson decay constant rises monotonously as temperature increases. The
inflection point of decay constant and the chiral susceptibility get the same
phase transition temperature. Though there is no access to the thermal width of
mesons within this scheme, it is discussed by analyzing the
Gell-Mann-Oakes-Renner (GMOR) relation in medium. These thermal properties of
hadron observables will help us understand the QCD phases at finite temperature
and can be employed to improve the experimental data analysis and heavy ion
collision simulations.Comment: 8 pages, 4 figures, matched the published versio
Leading-twist parton distribution amplitudes of S-wave heavy-quarkonia
The leading-twist parton distribution amplitudes (PDAs) of ground-state
and - and -quarkonia are calculated using a
symmetry-preserving continuum treatment of the meson bound-state problem which
unifies the properties of these heavy-quark systems with those of light-quark
bound-states, including QCD's Goldstone modes. Analysing the evolution of
and PDAs with current-quark mass, , increasing away
from the chiral limit, it is found that in all cases there is a value of for which the PDA matches the asymptotic form appropriate to QCD's
conformal limit and hence is insensitive to changes in renormalisation scale,
. This mass lies just above that associated with the -quark. At
current-quark masses associated with heavy-quarkonia, on the other hand, the
PDAs are piecewise convex-concave-convex. They are much narrower than the
asymptotic distribution on a large domain of ; but nonetheless deviate
noticeably from , which is the result in
the static-quark limit. There are also material differences between and
PDAs, and between the PDAs for different vector-meson polarisations,
which vanish slowly with increasing . An analysis of moments of the
root-mean-square relative-velocity, , in and
systems reveals that -contributions may be needed
in order to obtain a reliable estimate of matrix elements using such an
expansion, especially for processes involving heavy pseudoscalar quarkonia.Comment: 6 pages, 2 figures, 3 table
Energy-aware Graph Job Allocation in Software Defined Air-Ground Integrated Vehicular Networks
The software defined air-ground integrated vehicular (SD-AGV) networks have
emerged as a promising paradigm, which realize the flexible on-ground resource
sharing to support innovative applications for UAVs with heavy computational
overhead. In this paper, we investigate a vehicular cloud-assisted graph job
allocation problem in SD-AGV networks, where the computation-intensive jobs
carried by UAVs, and the vehicular cloud are modeled as graphs. To map each
component of the graph jobs to a feasible vehicle, while achieving the
trade-off among minimizing UAVs' job completion time, energy consumption, and
the data exchange cost among vehicles, we formulate the problem as a
mixed-integer non-linear programming problem, which is Np-hard. Moreover, the
constraint associated with preserving job structures poses addressing the
subgraph isomorphism problem, that further complicates the algorithm design.
Motivated by which, we propose an efficient decoupled approach by separating
the template (feasible mappings between components and vehicles) searching from
the transmission power allocation. For the former, we present an efficient
algorithm of searching for all the subgraph isomorphisms with low computation
complexity. For the latter, we introduce a power allocation algorithm by
applying convex optimization techniques. Extensive simulations demonstrate that
the proposed approach outperforms the benchmark methods considering various
problem sizes.Comment: 14 pages, 7 figure
Characterizing Deep Learning Package Supply Chains in PyPI: Domains, Clusters, and Disengagement
Deep learning (DL) package supply chains (SCs) are critical for DL frameworks
to remain competitive. However, vital knowledge on the nature of DL package SCs
is still lacking. In this paper, we explore the domains, clusters, and
disengagement of packages in two representative PyPI DL package SCs to bridge
this knowledge gap. We analyze the metadata of nearly six million PyPI package
distributions and construct version-sensitive SCs for two popular DL
frameworks: TensorFlow and PyTorch. We find that popular packages (measured by
the number of monthly downloads) in the two SCs cover 34 domains belonging to
eight categories. Applications, Infrastructure, and Sciences categories account
for over 85% of popular packages in either SC and TensorFlow and PyTorch SC
have developed specializations on Infrastructure and Applications packages
respectively. We employ the Leiden community detection algorithm and detect 131
and 100 clusters in the two SCs. The clusters mainly exhibit four shapes:
Arrow, Star, Tree, and Forest with increasing dependency complexity. Most
clusters are Arrow or Star, but Tree and Forest clusters account for most
packages (Tensorflow SC: 70%, PyTorch SC: 90%). We identify three groups of
reasons why packages disengage from the SC (i.e., remove the DL framework and
its dependents from their installation dependencies): dependency issues,
functional improvements, and ease of installation. The most common
disengagement reason in the two SCs are different. Our study provides rich
implications on the maintenance and dependency management practices of PyPI DL
SCs.Comment: Manuscript submitted to ACM Transactions on Software Engineering and
