We introduce a new class of equilibrium problems, known as mixed quasi invex equilibrium (or equilibrium-like) problems. This class of invex equilibrium problems includes equilibrium problems, variational inequalities, and variational-like inequalities as special cases. Several iterative schemes for solving invex equilibrium problems are suggested and analyzed using the auxiliary principle tech...

Recent facility location allocation problems are engaged with social, environmental and many other aspects, besides cost objectives.Obtaining a sustainable solution for such problems requires development of new mathematical modeling and optimization algorithms. In this paper, an uncapacitated dynamic facility location-network design problem with random budget constraints is considered. Social i...

We study how cultural distance affects the rejection of imposed institutions. To this purpose, we exploit the transplantation of Piedmontese institutions on Southern Italy which occurred during the Italian unification. We assemble a novel and unique dataset containing information on episodes of brigandage, a form of violent uprising against the unitary government, at the municipal level. We use...

It is important to understand urban auto markets from a spatial perspective. Specifically, the question of how to simplify and visualize the relatedness of the complicated urban markets arises. Based on the concept of ‘product space’, this research explores the similarity between Chinese cities and identifies the city clusters using data of automobile sales in 2012. A city’s automobile market i...

The objective of this paper is to develop a conceptual model for client-vendor distance in global IS outsourcing relationships as previous research on this issue is scarce. A multi-dimensional construct is deductively developed deploying the theory of psychic distance as a theoretical lens. A key finding is that client-vendor distance in global IS outsourcing relationships is constituted by sev...

This vignette describes gdistance, an R package which provides functionality to calculate various distance measures and routes in heterogeneous geographic spaces represented as grids. Distances are fundamental to geospatial analysis (Tobler 1970). The most commonly used geographic distance measure is the great-circle distance, which represents the shortest line between two points, taking into a...

Offshore software development projects provoke new issues to the collaborative endeavor of software development due to their global distribution and involvement of various people, processes, and tools. These problems relate to the geographical distance and the associated time-zone differences; cultural, organizational, and process issues; as well as language problems. However, existing tool sup...

the changing of round and back vowel /u/ to unround and front vowel [i] occurs in lori dialects as well as some other persian dialects. this vowel change includes both unrounding and fronting. this paper aimed at coming up with an inclusive ranking of constraints to explain occurrence and nonoccurrence of this vowel change in various phonological environments in silahkori dialect within optimal...
