Exploring Norm Establishment in Organizations Using an Extended Axelrod Model and with Two New Metanorms
Authors: Balaraman V, Singh M
(Summer Sim Multi-Conference 2014)

Abstract:

We examine norms establishment within organizations using an extended Axelrod model. Organizations have distinct differences in structure and function from other social groupings which makes for interest in this question. We examine two types of organizational norms and propose two new metanorms. The Walk-The-Talk (WTT) Metanorm is based on the intuition that the team leader who regularly violates a norm will, by setting a poor example, weaken the norm. Similarly the leader who conforms to the norm will strengthen the norm. The Corrective-Action Metanorm (CA) models the corrective action a team leader may take if she sees norm weakening. The metanorm is moderated by a personality variable which we call Introspectiveness. We show the differences in norm establishment and collapse without the metanorms, with only WTT at play and with both metanorms at play. We show how the WTT acts as a positive feedback loop as conformance triggers more conformance, violation more violations while the CA metanorm acts as the negative feedback loop trying to move things towards ideal norm states. We close with a look at the relation between team size and norm compliance and show how large teams appear to prevent norm collapse.

A Culture of Involving Vox Populi for Evolution of Workforce Policy,
Authors: Athle D, Kumar A, Katiyar V
CHASE 2014

Abstract
In this paper, we present a pilot study of software and other industries – such as research, advertising and education – designed to understand factors influencing work ethics, policy making, employee engagement and organizational culture, and to begin uncovering the interaction effects thereof. Past research reveals that these factors are highly relevant to both productivity and attrition. So we collected and analyzed data from 56 employees via a survey on self-beliefs and reports of work ethics related to both self and team. Preliminary analyses using demographics and psychographics were undertaken. Interestingly, we found that the two industries differed very little, on the variables measured. An interactionist perspective – according to which human attitude and behavior are a function of the fit between personality and the environment – and paying close heed to the voice of the employees or the vox populi are recommended.

Modeling Work-ethics Spread in Software Organizations,
Authors: Athavale S, Singh M,
CHASE 2014

Abstract:
Most organizations – whether software or otherwise – have a statement of mission, a vision for the future, and values that help them get there. People, on the other hand, have a wide range of ideas, beliefs and objectives. How does one reconcile the two? Otherwise put: how do work practices and ethics that are important from an organizational standpoint get inculcated in employees? We propose a Human Behavior Change model and apply it to the context of ethics spread in software organizations. The model is founded upon an internal cost-reward function of individuals and transmission effect between people that contributes to the decision to change and comply with certain ethics and practices. We use Agent Based Modeling and Simulation (ABMS) technique to represent our model. We experiment with virtual teams and create various scenarios to understand ethic spread. Although our larger aim is to model behavior change, in this early stage of our work, we build models to know how ethics spread through change in compliance behavior. We base our study on existing literature, a limited survey, some assumptions and simulation. Through simulation, we also seek to ask associated questions related to team size and compliance, spread of counter-ethics, message mechanism and speed of spread and the ‘mean time to change’ for different types of individuals.

Non-Linguistic Analysis of Call Center Conversations 
Author: Dr. Sunil Kumar Kopparapu
( ISBN: 978-3-319-00896-7 (Print) 978-3-319-00897-4 (Online)

 

Abstract:
The book focuses on the part of the audio conversation not related to language such as speaking rate (in terms of number of syllables per unit time) and emotion centric features. This text examines using non-linguistics features to infer information from phone calls to call centers. The author analyzes "how" the conversation happens and not "what" the conversation is about by audio signal processing and analysis.

A Tea-Serving Robot for Office Environment
Authors: Kumar Swagat, Garg Sourav, Kejrival Nishant
(ISR/Robotik 2014; 41st International Symposium on Robotics)

Abstract:
This paper provides implementation details of a tea-serving robot designed to operate reliably in an office environment where the robot has to move in a restricted space available between the desks. The robot has multiple modes of operation and has several capabilities like following a coloured-line marked on the floor, following a person, detecting hands approaching the tray, detecting an empty tray and avoiding obstacles. The emphasis of this work has been on improving the robustness and reliability of the whole system. A rigorous quantitative performance analysis is carried out to demonstrate the efficacy of the system.

Wireless Mobile Network Planning and Optimization: A Tool Based Approach
Authors: KNR Surya Vara Prasad, Hemant Kumar Rath and Anantha Simha

(IEEE COMSNETS 2014 - Received the Best Demo and Exhibits Award)

Abstract:
Optimal mobile network planning of greenfield or new networks and continuous optimization of existing networks are the key requirements for an operator to maintain Quality of Service (QoS) and improve Average Revenue Per User (ARPU). With various conflicting parameters involved in optimization process, the planning and optimization problem become NPhard; a real time solution is not possible. To facilitate planning and optimization for an operator, we design a tool which implements a simple and robust joint optimization technique using Clustering and Cooperative Game Theoretic algorithms to obtain near-optimal real time solution. Using our tool, we demonstrate that we can plan new networks effectively and also improve the performance of existing networks substantially.
