Noninfluentials and information dissemination in the microblogging community
(Springer Nature, 2017)Firms are increasingly focusing on understanding and managing their social media strategies in order to create discussions and optimize the spread of news in their communities. Most prior studies on information dissemination ... -
Numerical discretization of stochastic oscillators with generalized numerical integrators
(Vinča Institute of Nuclear Sciences, 2021)In this study, we propose a numerical scheme for stochastic oscillators with additive noise obtained by the method of variation of constants formula using generalized numerical integrators. For both of the displacement and ... -
On a family of coupled diffusions that can never change their initial order
(IOP Publishing, 2022-11-18)We introduce a real-valued family of interacting diffusions where their paths can meet but cannot cross each other in a way that would alter their initial order. Any given interacting pair is a solution to coupled stochastic ... -
On approximate Nash equilibria of the two-source connection game
(TÜBİTAK, 2022)The arbitrary-sharing connection game is prominent in the network formation game literature [1]. An undirected graph with positive edge weights is given, where the weight of an edge is the cost of building it. An edge is ... -
On efficient computation of equilibrium under social coalition structures
In game-theoretic settings the key notion of analysis is an equilibrium, which is a profile of agent strategies such that no viable coalition of agents can improve upon their coalitional welfare by jointly changing their ... -
On existence of equilibrium under social coalition structures
(Cambridge University Press, 2022-02)In a strategic-form game, a strategy profile is an equilibrium if no viable coalition of agents (or players) benefits (in the Pareto sense) from jointly changing their strategies. Weaker or stronger equilibrium notions can ... -
On existence of equilibrium under social coalition structures
(Springer, 2020)In a strategic form game, a strategy profile is an equilibrium if no viable coalition of agents benefits (in the Pareto sense) from jointly changing their strategies. Weaker or stronger equilibrium notions can be defined ... -
On member‐driven, efficient and fair timeshare exchanges
(Wiley, 2019-01)Vacation Timeshare is a form of ownership or "right to use" of a resort property for a specific time period (typically a week) each year. Timeshare exchange refers to the non-monetary trading of timeshare weeks among owners, ... -
On optimal toll design for bosporus crossings
(Sosyoekonomi Society, 2022-10)For many years, two toll bridges served commuter demand to cross the strait called Bosporus in Istanbul, Turkey. An underground connection called the Eurasian tunnel had been recently launched to relieve the strait's ... -
On singleton congestion games with resilience against collusion
(Springer, 2021)We study the subclass of singleton congestion games in which there are identical resources with increasing cost functions. In this domain, we prove that there always exists an outcome that is resilient to weakly-improving ... -
On the numerical schemes for Langevin-type equations
(Karaganda University, 2020)In this paper, a numerical approach is proposed based on the variation-of-constants formula for the numerical discretization Langevin-type equations. Linear and non-linear cases are treated separately. The proofs of ... -
Online intermediary as a channel for selling quality-differentiated services
(Wiley, 2015-02)When deciding whether to utilize an online intermediary in addition to their own distribution channels, quality differentiated service providers face the trade-off between the benefit of extended reach and the threat of ... -
Online social capital : understanding e-impulse buying in practice
(Elsevier, 2009-07)Socially constructed marketing imageries (e.g. e-atmospherics) help consumers while making choices and decisions. Still, human and retailing technology interactions are rarely evaluated from a social practice perspective. ... -
Optimal ambulance location with random delays and travel times
(Springer Science+Business Media, 2008-09)We describe an ambulance location optimization model that minimizes the number of ambulances needed tonprovide a specified service level. The model measures service level as the fraction of calls reached within a given ... -
Optimal peer-to-peer network for streaming multimedia broadcast
(Elsevier, 2020-11)This study identifies optimal transmission mechanisms for a streaming video service in a peer-to-peer network structure as a function of the number of active peers, a common service value, a common discount factor, and ... -
Optimistic entrepreneurs and new product introductions in high technology industries
(Academy of Management, 2018)This study examines how the relationship between past performance and new product introductions is influenced by entrepreneurial optimism. Based on the behavioral theory of the firm, we test how past performance suggest ... -
Optimized calibration of currency market strategies
(2010)We propose a new financial indicator and risk metric embedded in a currency trading model to assist investors in currency markets. Since our model is highly nonlinear, we utilize global optimization technology to maximize ... -
Optimizing offer sets based on user profiles
(Social Science Research Network, 2009)Personalization and recommendation systems are being increasingly utilized by ecommerce firms to provide personalized product offerings to visitors at the firms’ web sites. These systems often recommend, at each interaction, ... -
Order fulfillment policies for ship-from-store implementation in omni-channel retailing
(Elsevier, 2021-11-01)One of the recent trends in omni-channel retailing is ship-from-store which allows a retailer to fulfill online orders by using inventory from a nearby store. The benefits of this fulfillment model include faster delivery, ... -
Outpatient appointment scheduling in presence of seasonal walk-ins
(Springer Nature, 2014-04)This study investigates appointment systems (AS), as combinations of access rules and appointment-scheduling rules, explicitly designed for dealing with walk-in seasonality. In terms of 'access rules', strategies are tested ...
