Actors’ interaction in the ERP implementation literature
Abstract: Purpose – The purpose of this paper is to identify the existence of studies, by exploring the current literatures, on interaction among actors in Enterprise Resource Planning (ERP) implementation. Design/methodology/approach – A new classification framework is offered, along with the two dimensions of ERP implementation: determinants and outcomes, to provide four types of research classes. Hundreds of articles were searched by using keywords from journal data bases. The selected articles were grouped based on the new classification of ERP implementation, followed by an in-depth analysis by using the Context, Intervention, Mechanism, Outcomes logic and the system of systems methodologies (SOSM) framework. Findings – The interactions among actors in ERP implementation have been overlooked, although there is almost always disagreements, misperceptions, and conflicts. Managing the interactions among actors is considered important because common failures in ERP implementation are often caused by mismanaged interactions among the key actors. Unfortunately, the existing research has so far shown a small effort to study how the actors’ interactions are managed. Research limitations/implications – One key limitation of this research is that the number of actor-related articles is lesser than the factor-related articles. Further research should be conducted to explain how to manage the interactions among the actors in each stage of ERP implementation. Practical implications – A guidance to prepare the entire organization prior to the ERP implementation to seriously consider the typical conflict among actors on each stage of ERP implementation and its causal factors and how to resolve them. Social implications – The importance of understanding typical conflict among actors, its causal factors, and how to resolve them can be extended to other projects or social phenomenon. Originality/value – This proposed framework is new to the ERP literature and serves to identify and expand further research on actors’ interactions to improve the success of ERP implementation. This is the first research to identify the interactions among actors in ERP implementation by using a clearly structured methodological approach, which is conducted by critically reviewing the ERP implementation literature.

Distance k-Cost Effective Sets in the Corona and Lexicographic Product of Graphs
European Journal of Pure and Applied Mathematics
Let G be a connected graph and k ≥ 1 be an integer. The open k-neighborhood Nk G(v) of v ∈ V (G) is the set Nk G(v) = {u ∈ V (G) \ {v}: dG(u, v) ≤ k}. A set S of vertices of G is called distance k-cost effective of G if for every vertex u in S, |Nk G(u) ∩ (V (G) \ S)| − |Nk G(u) ∩ S| ≥ 0. The maximum cardinality of a distance k-cost effective set of G is called the upper distance k-cost effective number of G. In this paper, we characterized the distance k-cost effective sets in the corona and lexicographic product of two graphs. Consequently, the bounds or the exact values of the upper distance k-cost effective numbers of these graphs are obtained.

International Wound Journal, 2007
Six out of 10 patients with chronic wounds suffer from persistent wound pain. A multinational and multicentre, randomised, double-blind clinical investigation of 122 patients compared two moist wound-healing dressings, a non adhesive foam dressing with ibuprofen (62 patients randomised to Biatain-Ibu non adhesive, Coloplast A/S) with a non adhesive foam without ibuprofen (60 to Biatain non adhesive).The ibuprofen-foam was regarded successful, if the pain relief on a 5-point verbal rating scale was higher than the comparator without compromising safety, including appropriate healing rate. Additional endpoints were change in persistent wound pain between dressing changes and pain at dressing change on days 1-5 and days 43-47. The primary response variable, persistent pain relief, was significantly higher in the ibuprofen-foam group compared with the comparator on days 1-5, with a quick onset of action (P 0Á05). The patients in the ibuprofen-foam group had a significant (P 0Á05) higher reduction in the persistent wound pain from baseline (40%) as the comparator (30%).

2020
Abstract: In many repeated interactions, repetition is not guaranteed but instead must be agreed upon. We formulate a model of voluntary repetition by introducing outside options to a repeated Prisoner's Dilemma and investigate how the structure of outside options affects the sustainability of mutual cooperation. When the outside option is deterministic and greater than the value of mutual defection, the lower bound of the discount factors that sustain repeated cooperation is greater than the one for ordinary repeated Prisoner's Dilemma, making cooperation more difficult. However, stochastic outside options with the same mean may reduce the lower bound of discount factors as compared to the deterministic case. This is possible when the stochasticity of the options increases the value of the cooperation phase more than the value of the punishment phase. Necessary and sufficient conditions for this positive effect are given under various option structures.
