Recursive Methods In Discounted Stochastic Games: An Algorithm For Delta Approaching 1 And A Folk Theorem, Johannes Hörner, Takuo Sugaya, Satoru Takahashi, Nicolas Vieille

Cowles Foundation Discussion Papers

We present an algorithm to compute the set of perfect public equilibrium payoffs as the discount factor tends to one for stochastic games with observable states and public (but not necessarily perfect) monitoring when the limiting set of (long-run players’) equilibrium payoffs is independent of the state. This is the case, for instance, if the Markov chain induced by any Markov strategy profile is irreducible. We then provide conditions under which a folk theorem obtains: if in each state the joint distribution over the public signal and next period’s state satisfies some rank condition, every feasible payoff vector above the …

Tactical Analysis Of Attack In Physical And Digital Security Incidents:Towards A Model Of Asymmetry, Atif Ahmad

Australian Information Warfare and Security Conference

Asymmetric warfare is frequently described as a conflict where ‘weaker’ parties aim to offset their relatively inadequate resources by using particular strategies and tactics to their advantage. This research-in-progress paper develops a concept model of asymmetric warfare that represents the leverage available to the ‘weaker’ party over the ‘stronger’ party simply because the former is attacking rather than defending. Points of leverage include choice of timing, location, method of attack, best use of limited resources and time to prepare. The resulting concept model is used to discuss generic defensive strategies that can be applied by ‘stronger’ parties in the physical …

Ascent Of Asymmetric Risk In Information Security: An Initial Evaluation., Tobias Ruighaver, Matthew Warren, Atif Ahmad

Australian Information Warfare and Security Conference

Dramatic changes in the information security risk landscape over several decades have not yet been matched by similar changes in organizational information security, which is still mainly based on a mindset that security is achieved through extensive preventive controls. As a result, maintenance cost of information security is increasing rapidly, but this increased expenditure has not really made an attack more difficult. The opposite seems to be true, information security attacks have become easier to perpetrate and appear more like information warfare tactics. At the same time, the damage caused by a successful attack has increased significantly and may sometimes …

Information Security Disclosure: A Case Study, I Rosewall, M J. Warren

Australian Information Security Management Conference

New social networking systems such as Facebook are an ever evolving and developing means of social interaction, which is not only being used to disseminate information to family, friends and colleagues but as a way of meeting and interacting with "strangers" through the advent of a large number of social applications. This paper will focus upon the impact of Generation F - the Facebook Generation and their attitudes to security. The paper will be based around discussing the findings of a major UK case study and the implications that this has. The case study identifies 51 recommendations to improve the …

Strong Authentication For Web Services Using Smartcards, D S. Stienne, Nathan Clarke, Paul Reynolds

Australian Information Security Management Conference

The popularity of the Internet and the variety of services it provides has been immense. Unfortunately, many of these services require the user to register and subsequently login to the system in order to access them. This has resulted in the user having to remember a multitude of username and password combinations in order to use the service securely. However, literature has clearly demonstrated this is not an effective approach, as users will frequently choose simple passwords, write them down, share them or use the same password for multiple systems. This paper proposes a novel concept where Internet users authenticate …

Security Issues Challenging Facebook, S Leitch, M Warren

Australian Information Security Management Conference

The advancement in Internet and bandwidth capability has resulted in a number of new applications to be developed; many of these newer applications are described as being Web 2. A Web 2 application such as Facebook has allowed people around the world to interact together. One of the interesting aspects of Facebook is the use of third parties applications and the interactions that this allows.Not surprisingly, the problems that exist in the real world such as theft, fraud, vandalism also exist in online Web 2 environments. This paper explores and categorises several security issues within the Facebook environment. It contributes …

Improving An Organisations Existing Information Technology Policy To Increase Security, Shane Talbot, Andrew Woodward

Australian Information Security Management Conference

A security policy which includes the appropriate phases of implementation, enforcement, auditing and review is vital to protecting an organisations information security. This paper examined the information security policy of a government organisation in response to a number of perceived shortcomings. The specific issues identified relating to the organisations security policy as a result of this investigation were as follows: a culture of ignoring policies, minimal awareness of policies, minimal policy enforcement, policy updating and review ad hoc at best, policy framework, lengthy policy development and approval process, no compliance program, no formal non-compliance reporting and an apparent inconsistent enforcement …

Educational Innovation In Thailand: A Case Study, Kristan Morrison

International Education

The Ministry of Education in the country of Thailand recently announced the establishment of two distinct educational tracks – a conventional/ traditional track and an unconventional/ progressive/ alternative track. This decision was perhaps guided by the success of innovative pilot education programs in the country, collectively called “the Lighthouse Project.” This article is concerned with one program in this project – the Darunsikkhalai School for Innovative Learning (DSIL) –detailing what it has accomplished and the challenges it faces in attempting to bring about new definitions of learning and teaching in Thailand. In this article, a detailed description of the school, …

The Alberta Legal Services Mapping Project: Report For The Calgary Judicial District, Glynnis Lieb, Stephanie Abel, Mary Stratton, Diana Lowe

Canadian Forum on Civil Justice

The „justice system‟ is a fundamental and far-reaching component of our system of democracy in Alberta. It is not one united system but an institutionalized process to address criminal and civil conflicts. It is made up of a complexity of organizations with overlapping provincial and federal jurisdictions. There are substantive and procedural laws with four broad divisions: civil, family, criminal and administrative. Many of these laws and the legal services associated with them, function to avoid conflict and legal problems. Ideally, legal services work to resolve conflicts without resorting to the courts or tribunals, the purpose of which is to …

Selling Information, Johannes Hörner, Andrzej Skrzypacz

Cowles Foundation Discussion Papers

We study a dynamic buyer-seller problem in which the good is information and there are no property rights. The potential buyer is reluctant to pay for information whose value to him is uncertain, but the seller cannot credibly convey its value to the buyer without disclosing the information itself. Information comes as divisible hard evidence. We show how and why the seller can appropriate a substantial fraction of the value through gradual revelation, and how the entire value can be extracted with the help of a mediator.

Selling Information, Johannes Hörner, Andrzej Skrzypacz

Cowles Foundation Discussion Papers

We characterize optimal selling protocols/equilibria of a game in which an Agent first puts hidden effort to acquire information and then transacts with a Firm that uses this information to take a decision. We determine the equilibrium payoffs that maximize incentives to acquire information. Our analysis is similar to finding ex ante optimal self-enforcing contracts since information sharing, outcomes and transfers cannot be contracted upon. We show when and how selling and transmitting information gradually helps. We also show how mixing/side bets increases the Agent’s incentives.

Selling Information, Johannes Hörner, Andrzej Skrzypacz

Cowles Foundation Discussion Papers

An Agent who owns information that is potentially valuable to a Firm bargains for its sale, without commitment and certification possibilities, short of disclosing it. We propose a model of gradual persuasion and show how gradualism helps mitigate the hold-up problem (that the Firm would not pay once it learns the information). An example illustrates how it is optimal to give away part of the information at the beginning of the bargaining, and sell the remainder in dribs and drabs. The Agent can only appropriate part of the value of information. Introducing a third-party allows her to extract the maximum …

Inducible Heat Shock Protein 70 Enhances Human Papillomavirus Type 31 Genome Replication, Viral Capsid Protein Nuclear Localization And Progeny Virion Morphogenesis In Human Keratinocytes, Hebin Song

Biomedical Sciences ETDs

Human papillomaviruses (HPVs) are small, non-enveloped double stranded DNA viruses that demonstrate a strict species and cell type tropism for human epithelial cells. The association between high-risk HPV types and cervical cancer is well established. Additionally, HPVs have been implicated as causes in development of several other epithelial cancer types. Increasing data indicate heat shock proteins (HSPs) including inducible HSP70 (HSP70i) are involved in the replicative cycles of different viruses including adenoviruses, polyomaviruses (PyV), and some RNA viruses. Cell-free system studies implicate HSP70i in HPV11 genome replication with E1 and E2 proteins, and there is evidence that HSP70 is involved …

Pot1 Proteins In Green Algae And Land Plants: Dna-Binding Properties And Evidence Of Co-Evolution With Telomeric Dna, Eugene V. Shakirov, Xiangyu Song, Jessica A. Joseph, Dorothy E. Shippen

Biological Sciences Faculty Research

Telomeric DNA terminates with a single-stranded 3′ G-overhang that in vertebrates and fission yeast is bound by POT1 (Protection Of Telomeres). However, no in vitro telomeric DNA binding is associated with Arabidopsis POT1 paralogs. To further investigate POT1–DNA interaction in plants, we cloned POT1 genes from 11 plant species representing major branches of plant kingdom. Telomeric DNA binding was associated with POT1 proteins from the green alga Ostreococcus lucimarinus and two flowering plants, maize and Asparagus. Site-directed mutagenesis revealed that several residues critical for telomeric DNA recognition in vertebrates are functionally conserved in plant POT1 proteins. However, the plant proteins …

Mobile Workforce -- Amway, Suman Kumar Mittapally

Masters Theses & Doctoral Dissertations

More and more organizations are evaluating the best route to mobilize their workers, whether field service personnel, sales representatives or on the move executives.

Amway is the largest multi-level marketing (MLM) organization in the world. In Amway, one is recruited as an "independent" distributor of Amway products by buying a couple of hundred dollars' worth of the products from the one who recruits you, known as your "up line." Every distributor in turn tries to recruit more distributors. Income is generated by sales of products by the distributor plus "bonuses" from sales of his or her recruits and their recruit-descendents. …

How Do Animal Mitochondria Tolerate Water Stress?, Michael A. Menze, Steven C. Hand

Faculty Publications

The vast majority of animal species do not tolerate severe water stress, but the encysted embryo of the brine shrimp Artemia franciscana is an exceptionally useful organism to investigate physiological mechanisms for enduring extreme environmental insults. Any substantial reduction in cellular water poses a threat to survival. Nevertheless anhydrobiotic animals survive virtually complete loss of cellular water. The mechanisms that govern " life without water" (anhydrobiosis) are still not well understood. With certain exceptions, it seems that a recurring strategy for tolerating severe water loss involves the accumulation of both low molecular weight solutes (e.g., trehalose or other polyol) and …

Optimal Partitions For Eigenvalues, Blaise Bourdin, Dorin Bucur, Édouard Oudet

Faculty Publications

We introduce a new numerical method for approximating partitions of a domain minimizing the sum of Dirichlet-Laplacian eigenvalues of any order. First we prove the equivalence of the original problem and a relaxed formulation based on measures. Using this result, we build a numerical algorithm to approximate optimal configurations. We describe numerical experiments aimed at studying the asymptotic behavior of optimal partitions with large numbers of cells. © 2009 Society for Industrial and Applied Mathematics.
