3 - Developing Adaptive Islamic Law BPS Models for Islamic Finance
and Banking by Text Mining the Qurnian
Munir Majdalawieh, Associate Professor, Zayed University,
Academic City, Dubai, United Arab Emirates,
, Farhi Marir, Ahmed Al-dawoody
In this study we will attempt to develop a Quranic financial corpus and use
computational and analytical approaches to mine the Quran (the Muslim holy
book) and the Hadith (actions and words of the prophet Muhammad peace be
upon him) to uncover hidden knowledge on Islamic financial business processes
and controls. The knowledge acquired from this investigation will be translated
into an IFBPs model to be adapted by financial institutions when moving to
Islamic finance and banking.
4 - Randomized Matrix Algorithms in Parallel and
Distributed Environments
Jiyan Yang, Stanford University, 44 Olmsted Road, Stanford, CA,
United States of America,
We first review recent work on developing and implementing random projection
and random sampling algorithms for very large very overdetermined least squares
regression problems in parallel and distributed environments. We evaluate the
their performance on up to terabyte-sized data in existing distributed systems
using Spark. In the second part of the talk, we discuss how randomized linear
algebre can be used in low-rank factorization of large-scale matrix with
applications in bioimaging.

1 - Production Planning with Advance Demand Information using
Real Options
Geoffrey Chua, Assistant Professor, Nanyang Technological
University, 50 Nanyang Avenue, S3-B2A-04, Singapore, Si,

We consider a newsvendor in a B2C setting who sells a real option in period 1
ahead of the spot market in period 2 and find the optimal production and option
pricing decisions. We show that option selling is better than advance selling. We
also find two benefits of option selling: revenue management and demand
updating. For a market with two segments, we compare three policies: selling one
option to the higher segment, selling one option to both segments, and selling
one option to each segment.
2 - Optimal Promotion Strategy for a Service Firm with Delay
Sensitive Customers
Guangwen Kong, University of Minnesota, 111 Church Street SE,
Minneapolis, MN, 55414, United States of America,
Online social advertising tools such as Groupon generate new business for service
providers and at the same time generate new challenges. Discount-seeking
customers may impose externalities on the system that could drive away regular
customers. We analyze these trade-offs and devise recommendations as to when
would Groupon promotions be beneficial.
3 - Stockout Recovery under Consignment: The Role of Inventory
Ownership in Supply Chains
Rui Yin, Associate Professor, Arizona State University, Dept of
Supply Chain Management, W.P.Carey School of Business,
Tempe, AZ, 85287, United States of America, ,
Yan Dong, Kefeng Xu
We examine how a supply chain firm may implement an incentive contract under
inventory consignment to recover stockouts and to retain customers. We
formulate principal-agent models to capture the strategic interactions in a supply
chain and explore the impact of supply chain opportunisms on the value of
inventory consignment.
4 - Prioritization and Price-plus-delay Competition with Self-selecting
and Heterogeneous Customers
Arvind Sainathan, Nanyang Business School, 50 Nanyang
Avenue, Singapore, Singapore,
In service operations, with the absence of severe capacity constraints,
prioritization has been “taken for granted” and presumed to do better when
customers are heterogeneous in their delay sensitivities. We show that it is not
true when customers self-select. In particular, we identify two key novel aspects –
sufficient customer heterogeneity and customer composition – that become
crucial, due to self-selection and competition respectively, in determining the
performance of prioritization.

1 - Managerial Deviance in High-Volume Store Replenishment
Decisions: Cognition vs. Computation Power
Shivom Aggarwal, IE Business School, Instituto de Empresa, S.L.,
CIF: B823343, C/ Maria de Molina, 12 Bajo, Madrid, 28006,
Spain, , Antti Tenhiala
The behavior of deviating from recommendations of artificially intelligent systems
is rife and often encouraged. Past research has found that the ordering behavior
of managers is subjected to their incentives, but lacks investigation of its
antecedents and consequences. Using longitudinal data from a multi-site
implementation of an Automatic Store Replenishment (ASR) system in a retail
chain, this study investigates the factors that explain the success of managerial
decisions to deviate.
2 - Can Safe Drivers be Productive Too? Empirical Evidence from
Long-Duration Truck Trips
Debjit Roy, Associate Professor, Indian Institute of Management
Ahmedabad, Vastrapur, Ahmedabad, 380015, India,
Rene De Koster, Jelle De Vries
Road safety still remains a prime concern for public policy makers. Through
empirical investigation, we attempt to understand the relationship between safety
conscious drivers and their trip productivity for long route trips.
3 - A Behavioral Study of Service Recovery Process – Focusing on
the Compensation
Hyejeong Gwon, PhD Candidate, Korea University, 408 LG-
POSCO Business bldg., Anam-Dong,Seongbuk-Gu, Seoul, Korea,
Republic of, , Daeki Kim
Even though a company provides best service, the company cannot satisfy all the
customers and prevent all service failure. The proper service recovery, especially
the proper compensation can determine the level of customer satisfaction. On this
paper, we investigate the effect of compensation on customer satisfaction focusing
on its several dimensions after service failure.
4 - Complex Organisational Integration – A Behavioural Approach
Bernard M Groen, Dr, Durham University,
Durham Business School, Durham, DH1 5LB, United Kingdom,
Understanding the psychological aspects which underpin any organisational
change is considered to be increasingly vital in the 21st century. This paper
focuses on the implicit and explicit behaviour and the possible ‘dissonance’
between what teams say, and the actual behaviour displayed. I will briefly
evaluate the relative merits of explicit and implicit behavioural methods, before
drawing out the main reasons and provide useful solutions to increase the
likelihood of successful change.
