MONOPOL NAD ROBOM S PROSTORNIM ODRŽAVANJEM
This study addresses the effects of monopolistic firms\u27 location and guarantee time limit on pricing for
goods requiring high maintenance expenditure, such as elevators, televisions and computers. A spatial
maintenance model of two stages within a guaranteed time limit is outlined in this paper. Based on
this model, location, maintenance commitment and pricing are all characterized under a monopoly
situation. This paper outlines the optimal price and location for the monopolist. The effects of guarantee
time limit on price are discussed.Ovaj rad se bavi efektima koje lokacija i vremensko ograničenje garancije u monopolističkim tvrtkama
imaju na formiranje cijena robe koja zahtijeva visoke troškove održavanja, kao što su liftovi, televizori
i kompjuteri. U ovom radu iznosimo model prostornog održavanja u dva stupnja unutar garantiranog
vremenskog ograničenja. Na osnovu ovog modela, lokacija, obveza održavanja i formiranje
cijena se sve određuju u situaciji monopola. Rad donosi optimalne cijene i lokacije za monopolistu.
Raspravlja se i o učincima vremenskog ograničenja garancije na cijenu
Two Roads Diverged: A Semantic Network Analysis of Guanxi on Twitter
Guanxi, roughly translated as "social connection", is a term commonly used in
the Chinese language. In this research, we employed a linguistic approach to
explore popular discourses on Guanxi. Although sharing the same Confucian
roots, Chinese communities inside and outside Mainland China have undergone
different historical trajectories. Hence, we took a comparative approach to
examine guanxi in Mainland China and in Taiwan, Hong Kong, and Macau (TW-HK-M).
Comparing guanxi discourses in two Chinese societies aims at revealing the
divergence of guanxi culture. The data for this research were collected on
Twitter over a three-week period by searching tweets containing guanxi written
in Simplified Chinese characters and in Traditional Chinese characters. After
building, visualising, and conducting community detection on both semantic
networks, two guanxi discourses were then compared in terms of their major
concept sub-communities. This research aims at addressing two questions: Has
the meaning of guanxi transformed in contemporary Chinese societies? And how do
different socio-economic configurations affect the practice of guanxi? Results
suggest that guanxi in interpersonal relationships has adapted to a new family
structure in both Chinese societies. In addition, the practice of guanxi in
business varies in Mainland China and in TW-HK-M. Furthermore, an extended
domain was identified where guanxi is used in a macro-level discussion of state
relations. Network representations of the guanxi discourses enabled reification
of the concept and shed lights on the understanding of social connections and
social orders in contemporary China.Comment: under review. 29 pages + supplementary informatio
Universal impurity-induced bound state in topological superfluids
We predict a universal mid-gap bound state in topological superfluids,
induced by either non-magnetic or magnetic impurities in the strong scattering
limit. This universal state is similar to the lowest-energy Caroli-de
Gennes-Martricon bound state in a vortex core, but is bound to localized
impurities. We argue that the observation of such a universal bound state can
be a clear signature for identifying topological superfluids. We theoretically
examine our argument for a spin-orbit coupled ultracold atomic Fermi gas
trapped in a two-dimensional harmonic potential, by performing extensive
self-consistent calculations within the mean-field Bogoliubov-de Gennes theory.
A realistic scenario for observing universal bound state in ultracold K
atoms is proposed.Comment: 5 pages + 4 figures; published in PRL; see the relevant study in 1D:
