Violence Detection in Social Media-Review
Social media has become a vital part of humansâ day to day life. Different users engage with social media differently. With the increased usage of social media, many researchers have investigated different aspects of social media. Many examples in the recent past show, content in the social media can generate violence in the user community. Violence in social media can be categorised into aggregation in comments, cyber-bullying and incidents like protests, murders. Identifying violent content in social media is a challenging task: social media posts contain both the visual and text as well as these posts may contain hidden meaning according to the usersâ context and other background information. This paper summarizes the different social media violent categories and existing methods to detect the violent content.Keywords: Machine learning, natural language processing, violence, social media, convolution neural networ
Analisis Peranan Realtionship Age dalam Pembentukan Loyalitas Pelanggan Telepon Seluler
Has a loyal customer is a difficult dream realized by each company. Many previous studies have tried to build the concepts and theories of customer loyalty on products and services, including the mobile telecommunications industry. Experts argue that the formation of customer loyalty in the mobile telecommunication industry has different characteristics from the service industry general particularly the role of relationship age (lifespan) on customer loyalty. In this study, researchers wanted to know how the relationship age role in influencing the impact of relational equity, trusts, and cutomer satisfaction in building customer loyalty mobile phone. Customer loyalty in this study were divided into two dimensions that attitudinal loyalty and behavioral loyalty. Through a questionnaire study (N = 100) and treated with partial least square (PLS) found that in Indonesia relationship age does not have significant impact on the increase in the dimensions of loyalty on the mobile phone industry. The results also showed that the relational equity has a positive effect in increasing customer loyalty in the mobile telecommunication industry in Indonesia
Entanglement dynamics in presence of diversity under decohering environments
We study the evolution of entanglement of a pair of coupled, non-resonant
harmonic oscillators in contact with an environment. For both the cases of a
common bath and of two separate baths for each of the oscillators, a full
master equation is provided without rotating wave approximation. This allows us
to characterize the entanglement dynamics as a function of the diversity
between the oscillators frequencies and their mutual coupling. Also the
correlation between the occupation numbers is considered to explore the degree
of quantumness of the system. The singular effect of the resonance condition
(identical oscillators) and its relationship with the possibility of preserving
asymptotic entanglement are discussed. The importance of the bath's memory
properties is investigated by comparing Markovian and non-Markovian evolutions
Electronic lifetimes in ballistic quantum dots electrostatically coupled to metallic environments
We calculate the lifetime of low-energy electronic excitations in a
two-dimensional quantum dot near a metallic gate. We find different behaviors
depending on the relative values of the dot size, the dot-gate distance and the
Thomas-Fermi screening length within the dot. The standard Fermi liquid
behavior is obtained when the dot-gate distance is much shorter than the dot
size or when it is so large that intrinsic effects dominate. Departures from
the Fermi liquid behavior are found in the unscreened dipole case of small dots
far away from the gate, for which a Caldeira-Leggett model is applicable. At
intermediate distances, a marginal Fermi liquid is obtained if there is
sufficient screening within the dot. In these last two non-trivial cases, the
level width decays as a power law with the dot-gate distance
Atomic motions in the -region of glass-forming polymers: Molecular versus Mode Coupling Theory approach
We present fully atomistic Molecular Dynamics simulation results on a
main-chain polymer, 1,4-Polybutadiene, in the merging region of the -
and -relaxations. A real space analysis reveals the occurrence of
localized motions (``-like'') in addition to the diffusive structural
relaxation. A molecular approach provides a direct connection between the local
conformational changes reflected in the atomic motions and the secondary
relaxations in this polymer. Such local processes occur just in the time window
where the -process of the Mode Coupling Theory is expected. We show that
the application of this theory is still possible, and yields an unusually large
value of the exponent parameter. This result might originate from the
competition between two mechanisms for dynamic arrest: intermolecular packing
and intramolecular barriers for local conformational changes
(``-like'').Comment: 10 pages, 6 figure
