English language teaching (ELT) in Iran has experienced a turbulent history reflecting an often dynamic context and changing attitudes toward English, yet framed within a discourse of tolerance rather than one of embrace, as this study is going to show. The discourse was much brighter before the Islamic Revolution and this study reveals that there were much fewer adverse policies toward the spr...

Societies before the Industrial Revolution were dependent on the annual cycle of plant photosynthesis for both heat and mechanical energy. The quantity of energy available each year was therefore limited, and economic growth was necessarily constrained. In the Industrial Revolution, energy usage increased massively and output rose accordingly. The energy source continued to be plant photosynthe...

The aims of the study were to identify factors that may result in difficulties in intubation, and to compare the results obtained when an experienced and when a less experienced anaesthesiologist was involved. The 96 patients included in the study were evaluated for difficult intubation according to the following scales: Mallampati, upper lip bite test (ULBT) and Patil. The mobility of the cerv...

This paper is the first study that analyzes the drivers of political protest using longitudinal data from a critical revolution that changed –at least temporarily– the political landscape in a transition country. We make use of a rich dataset consisting of panel data collected before and after the so called “Orange” revolution in Ukraine. Our empirical approach tackles two different –and equall...

Before 1948, all legislative powers were vested in Malay rulers their respective states. The Rulers the makers of Federal Constitution through a constitutional development process, even though many parties drafted it. This paper applies legal methodology watanic jurisprudence. position is essential because they sovereign authorities that legitimized Federation Malaya Agreement, 1957, and Malaya...

I propose a new measure of common, time-varying tail risk for large cross sections of stock returns. Stock return tails are described by a power law in which the power law exponent is allowed to transition smoothly through time as a function of recent data. It is motivated by asset pricing theory and is estimable via quasi-maximum likelihood. Estimates indicate substantial time variation in sto...

In a distributed system, it is often important to detect the causal relationships between events, where event e1 is causally before event e2 if e1 happened before e2 and could possibly have aaected the occurrence of e2. In this paper we argue that it can be essential to security that a process determine, in the face of malicious attack, how two events are causally related. We formulate attacks ...

In this article, we present a particle filter (PF)-based track-before-detect (PF TBD) procedure for detection of extended objects whose shape is modeled by an ellipse. By incorporating of an existence variable and the target shape parameters into the state vector, the proposed algorithm performs joint estimation of the target presence/ absence, trajectory and shape parameters under unknown nuis...

Following the Islamic Revolution of 1979 in Iran, the trend of migration of physicians from the country continued. The total number of Iranian physicians migrated to the United States (US) increased from 1625 before revolution in 1974, to 5045 in 2010, thirty years post-revolution. The percentage of medical graduates migrating to the US, in the same period dropped from 15% to 5%. The reasons fo...
