Personality And Programming, Amy B. Woszczynski, Tracy C. Guthrie, Sherri Shade
Sherri Shade
Information systems students continue to struggle to successfully complete computer programming classes. Learning how to program is difficult, and failure and attrition rates in college level programming classes remain at an unacceptably high rate. Since many IS students take a programming course as part of their program of study, IS educators should better understand why IS students tend to achieve low success rates in programming courses and what can be done to improve success rates. Little research to date has addressed potential reasons for student failure in programming principles courses. Many educators simply assume that high failure rates are acceptable …

Research methodology focuses on a qualitative analysis of in-depth interviews with women who are self-described information security professionals. A primary goal of the study is to understand the perceptions of women in information security and determine …
Architectural Control And Value Migration In Layered Ecosystems: The Case Of Open-Source Cloud Management Platforms, Richard Tee, C. Jason Woodard
Architectural Control And Value Migration In Layered Ecosystems: The Case Of Open-Source Cloud Management Platforms, Richard Tee, C. Jason Woodard
C. Jason Woodard
Our paper focuses on strategic decision making in layered business ecosystems, highlighting the role of cross-layer interactions in shaping choices about product design and platform governance. Based on evidence from the cloud computing ecosystem, we analyze how concerns about architectural control and expectations regarding future value migration influence the design of product interfaces and the degree of openness to external contributions. We draw on qualitative longitudinal data to trace the development of two open-source platforms for managing cloud-based computing resources. We focus in particular on the emergence of a layered "stack" in which these platforms must compete with both vertically …
Direct Neighbor Search, Jilian Zhang, Kyriakos Mouratidis, Hwee Hwa Pang
Direct Neighbor Search, Jilian Zhang, Kyriakos Mouratidis, Hwee Hwa Pang
Kyriakos MOURATIDIS
In this paper we study a novel query type, called direct neighbor query. Two objects in a dataset are direct neighbors (DNs) if a window selection may exclusively retrieve these two objects. Given a source object, a DN search computes all of its direct neighbors in the dataset. The DNs define a new type of affinity that differs from existing formulations (e.g., nearest neighbors, nearest surrounders, reverse nearest neighbors, etc.) and finds application in domains where user interests are expressed in the form of windows, i.e., multi-attribute range selections. Drawing on key properties of the DN relationship, we develop an …

From Cyber Terrorism To State Actors’ Covert Cyber Operations, Jan Kallberg, Bhavani Thuraisingham
From Cyber Terrorism To State Actors’ Covert Cyber Operations, Jan Kallberg, Bhavani Thuraisingham
Jan Kallberg
Historically, since the Internet started to become a common feature in our lives, hackers have been seen as a major threat. This view has repeatedly been entrenched and distributed by media coverage and commentaries through the years. Instead the first twenty year of the Internet was acceptably secure, due to the limited abilities of the attackers, compared to the threat generated from a militarized Internet with state actors conducting cyber operations. In reality, the Internet have a reversed trajectory for its security where it has become more unsafe over time and moved from a threat to the individual to a …
Nuclear Deterrence In A Second Obama Term, Adam Lowther, Jan Kallberg
Nuclear Deterrence In A Second Obama Term, Adam Lowther, Jan Kallberg
Jan Kallberg
In the months prior to the 2012 presidential election in the United States, members of the Obama administration and sympathetic organizations inside the Beltway began floating the idea that the administration would pursue – after an Obama victory – further reductions in the US nuclear arsenal. With the ink still wet on the New ST ART Treaty, efforts to reduce the American arsenal to 1000 operationally deployed strategic nuclear weapons or, as some suggest, 500, is certainly premature. These efforts illustrate a poor understanding of nuclear deterrence theory and practice and the ramifications of a United States that lacks a …
Offensive Cyber: Superiority Or Stuck In Legal Hurdles?, Jan Kallberg
Offensive Cyber: Superiority Or Stuck In Legal Hurdles?, Jan Kallberg
Jan Kallberg
In recent years, offensive cyber operations have attracted significant interest from the non-Defense Department academic legal community, prompting numerous articles seeking to create a legal theory for cyber conflicts. Naturally, cyber operations should be used in an ethical way, but the hurdles generated by the legal community are staggering. At a time when the United States has already lost an estimated $4 trillion in intellectual property as a result of foreign cyber espionage, not to mention the loss of military advantage, focusing on what the United States cannot do in cyberspace only hinders efforts to defend the country from future …

Europe In A ‘Nato Light’ World - Building Affordable And Credible Defense For The Eu, Jan Kallberg, Adam Lowther
Europe In A ‘Nato Light’ World - Building Affordable And Credible Defense For The Eu, Jan Kallberg, Adam Lowther
Jan Kallberg
From an outsider’s perspective, the Common Security and Defense Policy and the efforts of the European Defense Agency are insufficient to provide Europe with the defense it will require in coming decades. While the European Union—particularly the members of the European Monetary Union—struggle to solve prolonged fiscal challenges, viable European security alternatives to an American-dominated security architecture are conspicuously absent from the documents and discussions that are coming from the European Council and at a time when the United States is engaged in an Asia-Pacific pivot. This is not to say that no thought has been given to defense issues. …
Cyber Operations Bridging From Concept To Cyber Superiority, Jan Kallberg, Bhavani Thuraisingham
Cyber Operations Bridging From Concept To Cyber Superiority, Jan Kallberg, Bhavani Thuraisingham
Jan Kallberg
The United States is preparing for cyber conflicts and ushering in a new era for national security. The concept of cyber operations is rapidly developing, and the time has come to transpose the conceptual heights to a broad ability to fight a strategic cyber conflict and defend the Nation in a cohesive way. Richard M. George, a former National Security Agency official, commented on recent developments: “Other countries are preparing for a cyberwar. If we’re not pushing the envelope in cyber, somebody else will.”1 Therefore, increased budgets are allocated to cyber operations research and education. The Defense Advanced Research Projects …

With sequestration looming—generating significant cuts to defense spending—the United States may find itself increasingly relying on nuclear and cyber deterrence as an affordable way to guarantee national sovereignty and prevent major conflict. While earlier defense planning and acquisitions were based on economic conditions that no longer exist, Congress’ options to balance the budget by cutting defense spending are politically palatable because far fewer American are “defense voters” than “social welfare voters,” according to a number of recent public opinion surveys.

Jan Kallberg
In releasing the United States Department of Defense’s (DoD) Sustaining U.S. Global Leadership: Priorities for 21st Century Defense and Defense Budget Priorities and Choices in January 2012, President Barack Obama and Secretary of Defense Leon Panetta offered a rationale for the administration’s reductions in defense spending. By stating that the shift in strategic direction is an effort to “put our fiscal house in order” and a response to the 2011 Budget Control Act, which requires DoD to reduce spending by $487 billion between fiscal years 2012 and 2021, the United States’ NATO partners in Europe were given considerable reason for …

A Survey Of Schema Matching Research, Roger Blake
A Survey Of Schema Matching Research, Roger Blake
Roger H. Blake
Schema matching is the process of developing semantic matches between two or more schemas. The purpose of schema matching is generally either to merge two or more databases, or to enable queries on multiple, heterogeneous databases to be formulated on a single schema (Doan and Halevy 2005). This paper develops a taxonomy of schema matching approaches, classifying them as being based on a combination schema matching technique and the type of data used by those techniques. Schema matching techniques are categorized as being based on rules, learning, or ontology, and the type of data used is categorized as being based …
Common Criteria Meets Realpolitik Trust, Alliances, And Potential Betrayal, Jan Kallberg
Common Criteria Meets Realpolitik Trust, Alliances, And Potential Betrayal, Jan Kallberg
Jan Kallberg
Common Criteria for Information Technology Security Evaluation has the ambition to be a global standard for IT-security certification. The issued certifications are mutually recognized between the signatories of the Common Criteria Recognition Arrangement. The key element in any form of mutual relationships is trust. A question raised in this paper is how far trust can be maintained in Common Criteria when additional signatories enter with conflicting geopolitical interests to earlier signatories. Other issues raised are control over production, the lack of permanent organization in the Common Criteria, which leads to concerns of being able to oversee the actual compliance. As …
Heuristic Algorithms For Balanced Multi-Way Number Partitioning, Jilian Zhang, Kyriakos Mouratidis, Hwee Hwa Pang
Heuristic Algorithms For Balanced Multi-Way Number Partitioning, Jilian Zhang, Kyriakos Mouratidis, Hwee Hwa Pang
Kyriakos MOURATIDIS
Balanced multi-way number partitioning (BMNP) seeks to split a collection of numbers into subsets with (roughly) the same cardinality and subset sum. The problem is NP-hard, and there are several exact and approximate algorithms for it. However, existing exact algorithms solve only the simpler, balanced two-way number partitioning variant, whereas the most effective approximate algorithm, BLDM, may produce widely varying subset sums. In this paper, we introduce the LRM algorithm that lowers the expected spread in subset sums to one third that of BLDM for uniformly distributed numbers and odd subset cardinalities. We also propose Meld, a novel strategy for …
Towards Cyber Operations The New Role Of Academic Cyber Security Research And Education, Jan Kallberg, Bhavani Thuraisingham
Towards Cyber Operations The New Role Of Academic Cyber Security Research And Education, Jan Kallberg, Bhavani Thuraisingham
Jan Kallberg
Abstract – The shift towards cyber operations represents a shift not only for the defense establishments worldwide but also cyber security research and education. Traditionally cyber security research and education has been founded on information assurance, expressed in underlying subfields such as forensics, network security, and penetration testing. Cyber security research and education is connected to the homeland security agencies and defense through funding, mutual interest in the outcome of the research, and the potential job market for graduates. The future of cyber security is both defensive information assurance measures and active defense driven information operations that jointly and coordinately …
Incremental Dcop Search Algorithms For Solving Dynamic Dcop Problems, William Yeoh, Pradeep Varakantham, Xiaoxun Sun, Sven Koenig
Incremental Dcop Search Algorithms For Solving Dynamic Dcop Problems, William Yeoh, Pradeep Varakantham, Xiaoxun Sun, Sven Koenig
Dr Xiaoxun Sun
Distributed constraint optimization problems (DCOPs) are well-suited for modeling multi-agent coordination problems. However, most research has focused on developing algorithms for solving static DCOPs. In this paper, we model dynamic DCOPs as sequences of (static) DCOPs with changes from one DCOP to the next one in the sequence. We introduce the ReuseBounds procedure, which can be used by any-space ADOPT and any-space BnB-ADOPT to find cost-minimal solutions for all DCOPs in the sequence faster than by solving each DCOP individually. This procedure allows those agents that are guaranteed to remain unaffected by a change to reuse their lower and upper …
Designer Satellite Collisions From Covert Cyber War, Jan Kallberg
Designer Satellite Collisions From Covert Cyber War, Jan Kallberg
Jan Kallberg
Outer space has enjoyed two decades of fairly peaceful development since the Cold War, but once again it is becoming more competitive and contested, with increased militarization. Therefore, it is important the United States maintain its space superiority to ensure it has the capabilities required by modern warfare for successful operations. Today is different from earlier periods of space development,1 because there is not a blatantly overt arms race in space,2 but instead a covert challenge to US interests in maintaining superiority, resilience, and capability. A finite number of states consider themselves geopolitical actors; however, as long as the United …

Waldo In The Light Of Austerity And Federal Debt Crisis, Part 2, Jan Kallberg
Jan Kallberg
Waldo’s predictions about the future for public administration describe five areas that would be problematic in the future: legitimacy, authority, knowledge, control, and confidence. Legitimacy includes not only that the government is legally legitimized but capable and focused on an intention to deliver the “good society.” Authority, according to Waldo, is the ability to implement policy with the acceptance of the people based on rationalism, expectations of public good, ethics, superior knowledge, and institutional contexts. Knowledge is institutional knowledge, the ability to arrange and utilize knowledge within the bureaucracy since coordination is the major challenge in knowledge management. Government has …
