The current paper tried to explore the lived experience of Iranian students at universities in recent years after commercialization and commodification of higher education followed by limitations on the public and governmental resources of the universities. Thus, a university student is reduced to a customer position. The aim of this research is to study the lived experience of students in an old comprehensive university in the capital of Iran. Since the goal of the researchers was to go near the students themselves to reveal the lived and perceived experiences of them with the interpretive paradigm as a methodology. The hermeneutic phenomenological research method was chosen with deep exploratory interviews as a data gathering tool. Deep exploratory interviews were fulfilled with a purposive sample of 25 university students on the data saturation basis. 250 main propositions were found from these interviews. The most important propositions extracted with the thematic analysis method showed that just 30 percent of experiences were positive but 70 percent of them were negative.

AbstractA transportation system has N vehicles with no capacity constraint which take passengers from a depot to various destinations and return to the depot. The trip times are considered to be independent and identically distributed random variables. The dispatch strategy at the depot is to dispatch immediately, or to hold any returning vehicles with the objective of minimizing the average wait per passenger at the depot, if passengers arrive at a uniform rate.Optimal control strategies and resulting waits are determined in the special case of exponentially distributed trip time for various N up to N = 15. For N ≫ 1, the nature of the solution is always to keep a reservoir of vehicles in the depot, and to decrease (increase) the time headway between dispatches as the size of the reservoir gets larger (smaller). For sufficiently large N, one can approximate the number of vehicles in the reservoir by a continuum and obtain analytic experession for the optimal dispatch rate as a function of the number of vehicles in the reservoir. For the optimal strategy, it is shown that the average number of vehicles in the depot is of order N1/3. These limit properties are expected to be quite insensitive to the actual trip time distribution, but the convergence of the exact properties to the continuum approximation as N → ∞ is very slow.

Defined primarily in terms of the exodus of the highly talented from the Southern countries to the North, the phenomenon known as "brain drain" has gained in importance during recent decades and years. Changing global conditions, unprecedented developments in information and electronic technology, globalization, and widening of the gap between the South and the North have focused attention on the brain drain. We begin this article by discussing the nature of the brain drain, briefly noting that it occurs in three settings: internal, regional, and global. Our argument here is that brain drain occurs in almost all societies, initially from poorer and impoverished rural areas to relatively rich and developing urban centers within national boundaries and later (or sometimes concurrently) to more developed and wealthy regions and neighboring countries.
