Taking countries of the Organization for Economic Co-operation and Development (OECD), this paper analyzes factors affecting their software piracy rate (SPR) by taking into account several economic and technological variables. The empirical results show that per capita GDP (PerGDP), inflation, consumer prices (ICP), unemployment rate (UR), and high-technology exports (HTE) have positive correla...

the present study aimed to investigate the characteristics of occupational accidents and frequency and severity of work related accidents in the construction industry among iranian insured workers during the years 20072011.the iranian social security organization (isso) accident database containing 21,864 cases between the years 2007-2011 was applied in this study. in the next step, total accid...

We define Canonical Form Minimal Recursion Semantics (CF-MRS) and prove that all the well-formed MRS structures generated by the MRS semantic composition algorithm are in this form. We prove that the qeq relationships are equivalent to outscoping relations when MRS structures are in this form. This result fills the gap between some underspecification formalisms and motivates defining a Canonica...

We show that a class of cases that has been previously studied in terms of learning of abstract phonological underlying representations (URs) can be handled by a learner that chooses URs from a contextually conditioned distribution over observed surface representations. We implement such a learner in a Maximum Entropy version of Optimality Theory, in which UR learning is an instance of semisupe...

This paper aims at bridging together the fields of Uncertain Reasoning and Knowledge Representation. The bridge we propose consists in the definition of a Hybrid Belief System, a general modular system capable of performing uncertain reasoning on structured knowledge. This system comprises two distinct modules, UR-mod and KR-mod: the UR-mod provides the uncertainty calculus used to represent un...

This paper addresses the problem of bridging the gap between the fields of Knowledge Renresentation OCR) and Uncertain Reasoning (UR). The prohosed solution consists of a framework for representing uncertain knowledge in which two components, one dealing with (categorical) knowledge and one dealing with uncertainty about this knowledge, are singled out. In this sense, the framework is “hybrid”....

non-linear time series models have become fashionable tools to describe and forecast stock market returns in recent years. a significant amount of evidence supports a negative relationship between volume and future returns. this suggests that volume could act as a suitable threshold variable in lstar and tar models. in this research, we compared the forecasting ability of lsatr and tar models w...

For P ∈ F2[z] with P (0) = 1 and deg(P ) ≥ 1, let A = A(P ) be the unique subset of N such that ∑ n≥0 p(A, n)zn ≡ P (z) (mod 2), where p(A, n) is the number of partitions of n with parts in A. Let p be an odd prime number, and let P be irreducible of order p ; i.e., p is the smallest positive integer such that P divides 1+ zp in F2[z]. N. Baccar proved that the elements of A(P ) of the form 2km...
