Intrinsic vs. extrinsic motivations of Master of Library and Information Science students: A cross-cultural comparative study

This study examined the career and learning motivation of students studying a Master of Library and Information Science (MLIS) degree programs at universities located in four different countries, namely the University of Hong Kong, National Taiwan Normal University, Peking University, and the University of Copenhagen. The MLIS students from these four universities were invited to take part in a self-completion online questionnaire survey, and 200 responses were collected in total. We discovered that their prior working experience in the library had an impact on their decision to pursue the MLIS program. We also categorized the career and learning motivation factors of MLIS learners into intrinsic and extrinsic factors, and discovered that the participants were motivated by both intrinsic and extrinsic factors to pursue their graduate studies in the Library and Information Science (LIS) field. We found that intrinsic factors influenced the students of University of Copenhagen significantly more than the other student groups, and this could be explained by Hofstede’s cultural dimensions. Our findings can assist with the formulation of development strategies for MLIS programs through a review of the LIS curriculum and help MLIS programs in different countries attract more people to pursue a career in LIS.preprin

Polytropic gas scalar field models of dark energy

In this work we investigate the polytropic gas dark energy model in the non flat universe. We first calculate the evolution of EoS parameter of the model as well as the cosmological evolution of Hubble parameter in the context of polytropic gas dark energy model. Then we reconstruct the dynamics and the potential of the tachyon and K-essence scalar field models according to the evolutionary behavior of polytropic gas model.Comment: 18 pages, 6 Figure

Cosmological implications of interacting polytropic gas dark energy model in non-flat universe

The polytropic gas model is investigated as an interacting dark energy scenario. The cosmological implications of the model including the evolution of EoS parameter $w_{\Lambda}$, energy density $\Omega_{\Lambda}$ and deceleration parameter $q$ are investigated. We show that, depending on the parameter of model, the interacting polytropic gas can behave as a quintessence or phantom dark energy. In this model, the phantom divide is crossed from below to up. The evolution of $q$ in the context of polytropic gas dark energy model represents the decelerated phase at the early time and accelerated phase later. The singularity of this model is also discussed. Eventually, we establish the correspondence between interacting polytropic gas model with tachyon, K-essence and dilaton scalar fields. The potential and the dynamics of these scalar field models are reconstructed according to the evolution of interacting polytropic gas.Comment: 19 pages, 3 figures, accepted by ijt

Statefinder diagnostic and w−w′w-w^{\prime} analysis for interacting polytropic gas dark energy model

The interacting polytropic gas dark energy model is investigated from the viewpoint of statefinder diagnostic tool and $w-w^{\prime}$ analysis. The dependency of the statefinder parameters on the parameter of the model as well as the interaction parameter between dark matter and dark energy is calculated. We show that different values of the parameters of model and different values of interaction parameter result different evolutionary trajectories in $s-r$ and $w-w^{\prime}$ planes. The polytropic gas model of dark energy mimics the standard $\Lambda$CDM model at the early time.Comment: 17 pages, 4 figures, ijtp accepte
