Blockbusters, Bombs and Sleepers: The income distribution of movies

The distribution of gross earnings of movies released each year show a distribution having a power-law tail with Pareto exponent $\alpha \simeq 2$. While this offers interesting parallels with income distributions of individuals, it is also clear that it cannot be explained by simple asset exchange models, as movies do not interact with each other directly. In fact, movies (because of the large quantity of data available on their earnings) provide the best entry-point for studying the dynamics of how ``a hit is born'' and the resulting distribution of popularity (of products or ideas). In this paper, we show evidence of Pareto law for movie income, as well as, an analysis of the time-evolution of income.Comment: 5 pages, 3 figures, to appear in Proceedings of International Workshop on Econophysics of Wealth Distributions (Econophys-Kolkata I), March 15-19, 200

Ekspresi dan Purifikasi Protein Rekombinan Non-Struktural NS1 Virus Dengue Serotipe 1 Strain Indonesia pada Pichia Pastoris

Dengue infection remains a public health problem in Indonesia. In the framework of the independence of the national product, pursued research and development of raw materials that can be used for diagnostic kit and vaccine candidates. The objective of this study was to express and purify recombinant proteins non-structural NS1 dengue virus serotype 1 (DENV-1) of Indonesia strain (915 846) in Pichia pastoris expression system with “halal” system that can be used for the development of diagnostic kits and vaccines. The dengue virus serotype 1 strain Indonesia (915846) was used to construct the NS1 DENV-1 gene by PCR. Then NS1 DENV-1 gene cloned into the vector pPICZαB and transformed into Pichia pastoris yeast cells, then verified with sequencing. Recombinant protein NS1 DENV-1 was secreted expression in P. pastoris. Characterization of antigenicity was did by ELISA, Western Blot and purified by the method of metal-chelating affinity chromatographic (MCAC) column. The recombinant protein with a size of 45 kDa secreted into the supernatant of P. pastoris with methanol induction and purified. The recombinant protein can bind to monoclonal antibodies and serum of patients infected with dengue virus serotype 1. These results indicate that the recombinant protein NS1 DENV-1 strain Indonesia (915 846) can be produced efficiently in P. pastoris secreted expression system is halal and still functional as an antigen that can be used for the development of diagnostic kits and vaccines

The statistical laws of popularity: Universal properties of the box office dynamics of motion pictures

Are there general principles governing the process by which certain products or ideas become popular relative to other (often qualitatively similar) competitors? To investigate this question in detail, we have focused on the popularity of movies as measured by their box-office income. We observe that the log-normal distribution describes well the tail (corresponding to the most successful movies) of the empirical distributions for the total income, the income on the opening week, as well as, the weekly income per theater. This observation suggests that popularity may be the outcome of a linear multiplicative stochastic process. In addition, the distributions of the total income and the opening income show a bimodal form, with the majority of movies either performing very well or very poorly in theaters. We also observe that the gross income per theater for a movie at any point during its lifetime is, on average, inversely proportional to the period that has elapsed after its release. We argue that (i) the log-normal nature of the tail, (ii) the bimodal form of the overall gross income distribution, and (iii) the decay of gross income per theater with time as a power law, constitute the fundamental set of {\em stylized facts} (i.e., empirical "laws") that can be used to explain other observations about movie popularity. We show that, in conjunction with an assumption of a fixed lower cut-off for income per theater below which a movie is withdrawn from a cinema, these laws can be used to derive a Weibull distribution for the survival probability of movies which agrees with empirical data. The connection to extreme-value distributions suggests that popularity can be viewed as a process where a product becomes popular by avoiding failure (i.e., being pulled out from circulation) for many successive time periods. We suggest that these results may apply to popularity in general.Comment: 14 pages, 11 figure

Behind film performance in China’s changing institutional context:The impact of signals

Grounded in signaling theory, this paper investigates the signals reflecting product quality, innovativeness, reputation and cultural background which influence film performance, i.e. film survival (duration on cinema screen) and box office success, in China’s changing institutional context. This market has grown substantially and still possesses potential for further development. However, China’s unique institutional context presents challenges. By examining an expanded range of potential signals, two of which have not previously been examined in the literature, namely imported films and enhanced format film formats such as 3D and IMAX, we develop a conceptual framework and argue that signaling theory needs to be combined with institutional context. Similar to findings for film industries in other countries, we find quality and reputational signals including budget, star power, sequels, and online consumer reviews to be important in China. However, unique results are also revealed. Chinese consumers react to an innovativeness signal in that they are specifically attracted to enhanced format films. Film award nominations and prizes are insignificant reputational signals. Once other signals are taken into account, imported films on average do not perform as well as domestic films. We link these findings to China’s unique institutional setting and offer important implications for management, recognizing the challenges to film companies of competing in an increasingly globalized market. The paper is also of relevance to policymakers given their continued efforts in shaping the development of China’s film industry

Quantifying Social Influence in an Online Cultural Market

We revisit experimental data from an online cultural market in which 14,000 users interact to download songs, and develop a simple model that can explain seemingly complex outcomes. Our results suggest that individual behavior is characterized by a two-step process–the decision to sample and the decision to download a song. Contrary to conventional wisdom, social influence is material to the first step only. The model also identifies the role of placement in mediating social signals, and suggests that in this market with anonymous feedback cues, social influence serves an informational rather than normative role

The effect of social interactions in the primary life cycle of motion pictures

We model the consumption life cycle of theater attendance for single movies by taking into account the size of the targeted group and the effect of social interactions. We provide an analytical solution of such model, which we contrast with empirical data from the film industry obtaining good agreement with the diverse types of behaviors empirically found. The model grants a quantitative measure of the valorization of this cul- tural good based on the relative values of the coupling between agents who have watched the movie and those who have not. This represents a measurement of the observed quality of the good that is extracted solely from its dynamics, independently of critics reviews.Comment: 9 Pages, 3 figure

Atividade antiinflamatória de carboidrato produzido por fermentação aquosa de grãos de quefir

Kefir, a symbiont microorganism suspension, presents benefic effects to health. Some kefir grains were cultivated in brown sugar, allowing to isolate a substance named CSQ. This was evaluated on a biologic essay of mouse foot edema, presenting an inhibitory activity of 30+4 % against carrageenan after the stimulus. It was observed that a cultivation mean containing sucrose, and not the milky mean, lead to the production of different sugar polymeric chains of kefir. The results in vivo suggest that the CSQ exerted an anti-inflammatory activity

The film business in the United States and Britain during the 1930s

Film was a most important product in the lives of the people during the 1930s. This paper sets out to analyse the underlying economic arrangements of the film industries of the U.S. and Britain during the decade in producing and diffusing this commodity-type to the population at large. In doing this, the paper finds a highly competitive industry that was built around showing films that audiences wanted to see, irrespective of the extent of vertical integration. It also examines the nature of the inter-relationship between the two industries and finds an asymmetry between the popularity of British films in the American market and that of American films in the British market. Our explanation for this is that the efforts of British firms on the American market were not sufficiently sustained to make a significant impact on American audiences
