Film Marketing Technique in Bangladesh-is YouTube Trailer the Most Effective Tool?

In recent times the film industry is becoming precisely phenomenon worldwide But formerly gathering knowledge about this specific issue film marketing theory strategy policy and hierarchical procedure should maintain while practising The research undertakes the historical analysis of films from the very past several marketing policies and practice of Bangla movies and tries to identify their strategy of marketing The questionnaire includes in-depth interviews of the audiences and the sampling procedure is purposive sampling The samples collected throughout the study explores the ethical issues of the essential film marketing techniques Drawing on the uses and Gratifications model of Active Audience Theory this study discovers the methods and conclude that YouTube Trailer is the most compelling film marketing technique Therefore identification of the marketing strategy is supportive of the film to be blockbuster or successful in the theatre and marketing of a movie generates countless impact to be widespread in the audienc

Optimal linear Glauber model

Contrary to the actual nonlinear Glauber model (NLGM), the linear Glauber model (LGM) is exactly solvable, although the detailed balance condition is not generally satisfied. This motivates us to address the issue of writing the transition rate ($w_j$) in a best possible linear form such that the mean squared error in satisfying the detailed balance condition is least. The advantage of this work is that, by studying the LGM analytically, we will be able to anticipate how the kinetic properties of an arbitrary Ising system depend on the temperature and the coupling constants. The analytical expressions for the optimal values of the parameters involved in the linear $w_j$ are obtained using a simple Moore-Penrose pseudoinverse matrix. This approach is quite general, in principle applicable to any system and can reproduce the exact results for one dimensional Ising system. In the continuum limit, we get a linear time-dependent Ginzburg-Landau (TDGL) equation from the Glauber's microscopic model of non-conservative dynamics. We analyze the critical and dynamic properties of the model, and show that most of the important results obtained in different studies can be reproduced by our new mathematical approach. We will also show in this paper that the effect of magnetic field can easily be studied within our approach; in particular, we show that the inverse of relaxation time changes quadratically with (weak) magnetic field and that the fluctuation-dissipation theorem is valid for our model.Comment: 25 pages; final version; appeared in Journal of Statistical Physic

Out-of-equilibrium Kondo Effect in a Quantum Dot: Interplay of Magnetic Field and Spin Accumulation

We present a theoretical study of low temperature nonequilibrium transport through an interacting quantum dot in the presence of Zeeman magnetic field and current injection into one of its leads. By using a self-consistent renormalized equation of motion approach, we show that the injection of a spin-polarized current leads to a modulation of the Zeeman splitting of the Kondo peak in the differential conductance. We find that an appropriate amount of spin accumulation in the lead can restore the Kondo peak by compensating the splitting due to magnetic field. By contrast when the injected current is spin-unpolarized, we establish that both Zeeman-split Kondo peaks are equally shifted and the splitting remains unchanged. Our results quantitatively explain the experimental findings reported in KOBAYASHI T. et al., Phys. Rev. Lett. 104, 036804 (2010). These features could be nicely exploited for the control and manipulation of spin in nanoelectronic and spintronic devices.Comment: 6+ pages; 3 figures; final versio

Helicase processivity and not the unwinding velocity exhibits universal increase with force

Helicases, involved in a number of cellular functions, are motors that translocate along singlestranded nucleic acid and couple the motion to unwinding double-strands of a duplex nucleic acid. The junction between double and single strands creates a barrier to the movement of the helicase, which can be manipulated in vitro by applying mechanical forces directly on the nucleic acid strands. Single molecule experiments have demonstrated that the unwinding velocities of some helicases increase dramatically with increase in the external force, while others show little response. In contrast, the unwinding processivity always increases when the force increases. The differing responses of the unwinding velocity and processivity to force has lacked explanation. By generalizing a previous model of processive unwinding by helicases, we provide a unified framework for understanding the dependence of velocity and processivity on force and the nucleic acid sequence. We predict that the sensitivity of unwinding processivity to external force is a universal feature that should be observed in all helicases. Our prediction is illustrated using T7 and NS3 helicases as case studies. Interestingly, the increase in unwinding processivity with force depends on whether the helicase forces base pair opening by direct interaction or if such a disruption occurs spontaneously due to thermal uctuations. Based on the theoretical results, we propose that proteins like single-strand binding proteins associated with helicases in the replisome, may have co-evolved with helicases to increase the unwinding processivity even if the velocity remains unaffected

Adoption of Knowledge Management Systems: A Study on How Wiki Systems Should Be Adopted by Minimizing the Risk of Failure

“Knowledge is power”. Knowledge is an important asset for any organization. Many organization are now considering knowledge as an intellectual property. Thus the emergence of organizational knowledge management technologies are observed especially in the twenty-first century. Many companies are seen investing heavily in developing or purchasing knowledge management systems (KMS). Among all the systems of knowledge management, wiki is one of the most popular system, which is easy to use, cost effective and required low maintenance. Hence hundreds of companies are currently using wiki as the central repository system. Unfortunately several researchers have identified that the technology adoption is sometimes very risky as the failure rate is very high, which may often cause huge financial losses if it fails to address the problem. In response to those researches, this study is done to know how wiki system should be adopted by overcoming the risk of failure. In order to meet the purpose of this study two success stories of wiki adoption by NBC universal and Peacock production were analyzed. The result shows that, in order to minimize the risk of failure to adopt a KM system, a company needs to choose the system based on functional, non-functional and transitional requirements for the system, as well as organizational strength and capacities. A particular KM system should be chosen, only if the system can meet all the requirements of KM processes. The organizational structure and the system functionality should be matched before adopting the system. The result also suggests, if the users of the system are collaborative, have the will to share the valuable knowledge and motivated enough to use and apply the knowledge gained from the knowledge management system like wiki in day to day operations, the success rate of KMS adoption and implementation increases. Due to the limitation of time only two success case stories were evaluated and since this is not an empirical study additional care should be taken in generalizing the research findings.
