ABSTRACT The present material is the result of a sociologic research among 615 Romanians who emigrated in 5 devel-oped countries from Europe. The main objective was that to know the difficulties that they face on the territory of other countries and to find who helps them to solve these problems.

Consider the following two sentences: (1) I see a dark discoloration in the back of my hand. (2) I feel a jabbing pain in the back of my hand. They seem to have the same surface grammar, and thus prima facie invite the same kind of semantic treatment. Even though a reading of ‘see ’ in (1) where the verb is not treated as a success verb is not out of the question, it is not the ordinary and natural reading. Note that if I am hallucinating a dark discoloration in the back of my hand, then (1) is simply false. For (1) to be true, therefore, I have to stand in the seeing relation to a dark discoloration in the back of my hand, i.e., to a certain surface region in the back of my hand marked by a darker shade of the usual color of my skin, a certain region that can be seen by others possibly in the same way in which I see it. Also note that although the truth of (1) doesn’t require the possession of any concept by me expressed by the words making up the sentence, my uttering of (1) to make a report typically does — if we take such utterances as expressions of one’s thoughts. So my seeing would typically induce me to identify something in the back of my hand as a

We describe a method for reducing the complexity of temporal logic model checking in systems composed of many parallel processes. The goal is to check properties of the components of a system and then deduce global properties from these local properties. The main difficulty with this type

In this paper, we provide a systematic comparison of various evolutionary approaches to multiobjective optimization using six carefully chosen test functions. Each test function involves a particular feature that is known to cause difficulty in the evolutionary optimization process, mainly

developments are discussed, including some for dealing with missing data that are not MAR. Although not yet in the main-stream, these procedures may eventually extend the ML and MI methods that currently represent the state of the art. Why do missing data create such difficulty in sci-entific research? Because

Multi-objective evolutionary algorithms which use non-dominated sorting and sharing have been mainly criticized for their (i) -4 computational complexity (where is the number of objectives and is the population size), (ii) non-elitism approach, and (iii) the need for specifying a

Multi-objective evolutionary algorithms which use non-dominated sorting and sharing have been mainly criticized for their (i) O(MN computational complexity (where M is the number of objectives and N is the population size), (ii) non-elitism approach, and (iii) the need for specifying a sharing

. At the least, this increases the difficulty of testing the theory in on-going organizations. It also limits the degree to which the theory can be used to diagnose jobs prior to planned change, or to evaluate the effects of work redesign activities after changes have been carried out. Activation theory. While

is developed through a series of propositions. Then some implications of the model are outlined, including (1) the difficulty of bringing about change in organizations, (2) the utility of personality and interest measures for understanding organizational behavior, (3) the genesis of organizational climate

. If the validation succeeds, the code is guaranteed to respect the safety policy without relying on run-time checks. The main practical difficulty of PCC is in generating the safety proofs. In order to gain some preliminary experience with this, we have written several network packet filters in hand-tuned DEC Alpha
