this paper aims to explore the relationship between iranian cinema and iranian society and tries to evaluate the potentials of iranian cinema in depicting the multiplicity of social fact. a functional distribution of films was used in order to describe this multiplicity. the 12 years were divided into three periods: the pre-kahtami era, and the first and second khatami administrations. the film...

Inter-event times have been studied across various disciplines in search for correlations. In this paper, we show analytical and numerical evidence that at the population level a power-law can be obtained by assuming Poissonian agents with different characteristic times, and at the individual level by assuming Poissonian agents that change the rates at which they perform an event in a random or...

Discrete event simulation is an important system analysis technique. But for today’s demand for speed, the time to complete a simulation study is considered to be long, even with current developments in hardware and simulation software. In this scenario, simplification methods for simulation models could play a key role. This paper proposes a technique for reducing the complexity of a discrete ...

Morris (1996, 1997) introduced preference-based definitions of knowledge of belief in standard state-space structures. This paper extends this preference-based approach to unawareness structures (Heifetz, Meier, and Schipper, 2006, 2008). By defining unawareness and knowledge in terms of preferences over acts in unawareness structures and showing their equivalence to the epistemic notions of un...

BACKGROUND Since 2006, the empiric use of azithromycin in women at risk of premature birth has become prevalent in our institution without any evidence of its efficacy. Although antibiotics can prolong pregnancy in preterm prolonged rupture of membranes, no published data are available for women with intact membranes. OBJECTIVES To describe the purpose of adding azithromycin to the usual trea...

The effect of resource pulses, such as rainfall events, on soil respiration plays an important role in controlling grassland carbon balance, but how shifts in long-term precipitation regime regulate rain pulse effect on soil respiration is still unclear. We first quantified the influence of rainfall event on soil respiration based on a two-year (2006 and 2009) continuously measured soil respira...

In the early stages of meiosis, all the telomeres in the cell attach to the nuclear envelope and gather near the centrosome. This polarized chromosomal array is known as the bouquet, as the clustered telomeres resemble the gathered stems of a floral arrangement. In this issue of Cell, Chikashige et al. (2006) provide intriguing clues about the molecular details underlying this conserved meiotic...
