3 - Determinants For A Sustainable Relationship In Outsourcing –
A Case Study

The growing dependence of firms on service providers for achieving competitive
advantage has necessitated the development of long-term sustainable relationship
with them. Opportunism has been recognized as one of the vulnerabilities
affecting an enduring relationship. The objective of this paper is to examine the
antecedents of opportunism and identify their effects on the exchange
relationship in the context of outsourcing for the coal mining organization in
India.
4 - Strategic Disclosure Of Environmental And Social Performance:
Greenwashing In Supply Chains Under Activist Pressure

Economic gains derived by firms from voluntarily disclosing positive and negative
environmental and social performances are generally complicated. Greenwashing
occurs when a firm voluntarily discloses information about its performances in
such a way that it portrays an overall greener image than what it actually is. We
characterize a firm’s optimal policy for disclosure of environmental and social
performances under non-linear and non-monotonic economic gains from
disclosure derived by the firm. Further, we study the efficacy of activist power of
penalizing a greenwashing firm in accordance with the magnitude of
greenwashing, as opposed to penalizing according to a fixed penalty.

1 - Finding A Hider By An Unknown Deadline

An object is hidden among several locations. Each search at the object’s location
independently finds the object with some location-dependent probability. The
goal is to find the object by a deadline, but the deadline is unknown. Assuming
the worst-case scenario, where Nature knows the deadline and uses this
knowledge to hide the object to hinder the search, this paper shows that there is a
randomized search strategy that simultaneously maximizes the probability of
finding the object by any deadline.
2 - Planning Effective Police Patrol Routes On Urban Road Networks
Ruben Dario Yie Pinedo, Universidad del Norte, Barranquilla,
Colombia, Andrea Margarita Ditta Narváez
It is well-known that police patrolling is one of the best preventive practices for
public safety against urban crimes. This work, deals with the problem of planning
police patrol routes to minimize the overall risk at minimum cost. A specific
mathematical formulation models the problem, under critical time constraints and
resources. Algorithms of local search and evolutionary techniques, offers effective
solutions for this model. A case study in Barranquilla (Colombia), allows validate
the performance of our approach in real scenarios.
3 - Modeling Long Term Radiation Fatalities In The National
Operational Environment Model
Venkat Venkateswaran, Rensselaer Polytechnic Institute,
Room 725, RPI-Hartford, Hartford, CT, 06120, United States,
The National Operational Environment Model is a systems dynamics model that
recreates in software a model of any nation of interest. The goal is to capture the
essential features of the nation so that an analyst can then simulate and analyze
in software different intervention actions. We describe our models for estimating
long term radiation fatalities arising from a nuclear explosion. They are based on
the latest update of the long-running Life Span Study which we briefly describe.
These long term fatalities appear in two disease groups: cancers and heart and
circulatory diseases.
4 - Development Of Text Analytic Tools Focused On Application To
Military Specific Corpora
Nathan L Parker, MAJ, TRADOC Analysis Center - Monterey,
700 Dyer Road, Room 178, Monterey, CA, 93943, United States,
Theodore T Allen, Zhenhuan Sui
Large volumes of free text data present many challenges to analysts, especially
when working in time-constrained environments. This research focuses on the
development of text analytic tools, primarily topic model based, that can enable
military analyst to quickly process large free text data sets. This presentation will
discuss our research into text analytic tool development, including supporting
visualizations, along with the application of the tools in several field use cases.

1 - Assessing The Long-term Value Of Non-clinical Prevention:
Improving Life Paths Through Early Childhood Investments
George J. Miller, Institute Fellow, Altarum Institute, 3520 Green
Court, Suite 300, Ann Arbor, MI, 48105, United States,
Charles Roehrig
We illustrate use of a life-path approach to estimate the long-term benefits of
early childhood interventions such as perinatal home visits and preschool
education. A life path describes an age cohort’s progression through the life
course, as characterized by rates of morbidity, mortality, health care costs,
earnings, incarceration, and public support. The approach represents the effects of
an intervention as a shift from one multi-dimensional life path to a more
favorable one and estimates the associated economic value to potential investors,
including federal, state, and local governments.
2 - A System Dynamic Model Of Human Papillomavirus Vaccination

Human papillomavirus (HPV) is a sexually transmitted infection (STI), with a
8.1% incidence rate among boys aged 13-17 years within United States. Although
HPV vaccination is available, however the vaccination rate in 2014 was only 22%
among boys. It is necessary to study the barriers and facilitators in increasing the
uptake of the vaccine among this group of adolescents. In this paper we use a
system dynamics simulation method to understand how psychological, socio-
economic, and health system factors influence the completion of recommended
series of HPV vaccination among adolescents boys.
3 - Hospital Payment Schemes Under Competition
Zheng Han, University of Kansas, Lawrence, KS, United States,

We consider two hospitals competing for patients and operating under different
payment schemes. Using a game-theoretic approach, we determine equilibrium
operating parameters and develop intuitions for healthcare policies.
4 - Sequential Planning For Steering Immune System Adaptation

Biological adaptation is a powerful mechanism that makes many disorders hard to
combat. We study steering adaptation through sequential planning. We propose a
general approach that leverages Monte Carlo tree search to compute a treatment
plan, and the biological entity is modeled by a simulator. We apply the framework
to a leading T cell simulator. We run experiments with two alternate goals:
developing regulatory T cells or effector T cells. The former is key for preventing
autoimmune diseases; the latter is associated with better survival rates in cancer
patients. We show that for the development of regulatory cells, sequential plans
yield significantly higher utility than the best static therapy.
