The future of marketing will be shaped by the Internet. Typical push-based marketing techniques have decreased in effectiveness due to the amount of information available on the Internet. In order to survive in the future, companies will need to adapt trust-based marketing techniques in order to survive on the Internet. The E-business group at MIT Sloan under the guidance of Prof. Urban is working on a website that applies trust techniques for GM. Automobile manufacturers, GM among them, have suffered from low trust levels from consumers. The purpose of this project is to determine whether certain trust factors in a website improve consideration and trust in GM. A large part of the website My Auto Advocate involves using advanced computer science algorithms and techniques in building the trust-based site. This thesis concentrates on what computer science problems are presented by building a trust-based site and how these problems are solved and implemented.; by Stephen Kao.; Thesis (M.

Scientific studies about bibliographic productions in specific areas of science are becoming common, mainly in the last decade. Such investigations usually make use of bibliometric indices to evaluate relevance of the actors that take part in scientific production process, such as: authors, institutions, venues, and subfields of the scientific area being considered. Many studies have investigated the scientific production in computer science under different views. In this work, its presented an analysis about the production of scientific article in computer science and an analysis of citations among subfields, derived from article citation network. The work present novelty not only because it considers many common sense fields in computer science, but also because it presents citation related measures chronologically. The following bibliometric measures were used: number of publications in each subfield, number of citations received by a subfield, Impact Factor, PageRank, and a measure of diversity of subfields that cite a given subfield. Most of those metrics were proposed to study articles, web pages or scientific journals and they had to be adapted to be applied to the subfield analysis. This work has derived many interesting information to computer science community. It presents an historical evolution of the computer science subfields...

Despite increased attention from Universities and Industry, the low representation of female students in Computer Science undergraduate degrees remains a major issue. Recognising this issue, leading tech companies have established strong and committed diversity initiatives but have only reached up to 17\% female representation in their tech departments. The causes of the reduced attraction and retention of female students are varied and have been widely studied, advancing the understanding of why female students do not take up or leave Computer Science. However, few analyses look at the perceptions of the females that have stayed in the field. In this paper, we explore the viewpoints of female academics and postgraduate students in Computer Science with various undergraduate backgrounds and pathways into academia. Our analysis of their interviews shows the influence of family, exposure, culture, sexism and gendered thought on their perceptions of the field, and of themselves and their peers. We identify that perceptions of identity conflict and a lack of belonging to the discipline persist even for these high-performing professionals.; Katrina Falkner, Claudia Szabo, Dee Michell, Anna Szorenyi, Shantel Thyer

peer-reviewed; While it is universally held by computer scientists that conference publications have a higher status in computer science than in other disciplines there is little quantitative evidence in support of this position. The importance of journal publications in academic promotion makes this a big issue since a focus on journal papers only will miss many signi cant papers published at conferences in computer science. In this paper we set out to quantify the relative importance of journal and conference papers in computer science. We show that computer science papers in leading conferences match the impact of papers in mid-ranking journals and surpass the impact of papers in journals in the bottom half of the ISI rankings { when impact is measured by citations in Google Scholar. We also show that there is a poor correlation between this measure of impact and conference acceptance rates. This indicates that conference publication is an ine cient market where venues that are equally challenging in terms of rejection rates o er quite di erent returns in terms of citation.

A computer can never be too fast or too cheap. Computer systems pervade nearly every aspect of science, engineering, communications and commerce because they perform certain tasks at rates unachievable by any other kind of system built by humans. A computer system's throughput, however, is constrained by that system's ability to find concurrency. Given a particular target work load the computer architect's role is to design mechanisms to find and exploit the available concurrency in that work load. This thesis describes SUDS (Software Un-Do System), a compiler and runtime system that can automatically find and exploit the available concurrency of scalar operations in imperative programs with arbitrary unstructured and unpredictable control flow. The core compiler transformation that enables this is scalar queue conversion. Scalar queue conversion makes scalar renaming an explicit operation through a process similar to closure conversion, a technique traditionally used to compile functional languages. The scalar queue conversion compiler transformation is speculative, in the sense that it may introduce dynamic memory allocation operations into code that would not otherwise dynamically allocate memory. Thus, SUDS also includes a transactional runtime system that periodically checkpoints machine state...

This volume contains the proceedings of the Tenth International Workshop on Fixed Points in Computer Science (FICS 2015) which took place on September 11th and 12th, 2015 in Berlin, Germany, as a satellite event of the conference Computer Science Logic (CSL 2015). Fixed points play a fundamental role in several areas of computer science. They are used to justify (co)recursive definitions and associated reasoning techniques. The construction and properties of fixed points have been investigated in many different settings such as: design and implementation of programming languages, logics, verification, databases. The aim of this workshop is to provide a forum for researchers to present their results to those members of the computer science and logic communities who study or apply the theory of fixed points. Each of the 11 contributed papers of this volume were evaluated by three or four reviewers. Some of the papers were re-reviewed after revision. Additionally, this volume contains the abstracts of the FICS 2015 invited talks given by Bartek Klin and James Worrell.

Over 15 years of teaching, advising students and coordinating scientific research activities and projects in computer science, we have observed the difficulties of students to write scientific papers to present the results of their research practices. In addition, they repeatedly have doubts about the publishing process. In this article we propose a conceptual framework to support the writing and publishing of scientific papers in computer science, providing a kind of guide for computer science students to effectively present the results of their research practices, particularly for experimental research.; Comment: 2 pages, 2 figures, Brazilian Portuguese

Modern society is permeated with computers, and the software that controls them can have latent, long-term, and immediate effects that reach far beyond the actual users of these systems. This places researchers in Computer Science and Software Engineering in a critical position of influence and responsibility, more than any other field because computer systems are vital research tools for other disciplines. This essay presents several key ethical concerns and responsibilities relating to research in computing. The goal is to promote awareness and discussion of ethical issues among computer science researchers. A hypothetical case study is provided, along with questions for reflection and discussion.; Comment: Written as central essay for the Computer Science module of the LANGURE model curriculum in Research Ethics

Co-authorship in publications within a discipline uncovers interesting properties of the analysed field. We represent collaboration in academic papers of computer science in terms of differently grained networks, including those sub-networks that emerge from conference and journal co-authorship only. We take advantage of the network science paraphernalia to take a picture of computer science collaboration including all papers published in the field since 1936. We investigate typical bibliometric properties like scientific productivity of authors and collaboration level in papers, as well as large-scale network properties like reachability and average separation distance among scholars, distribution of the number of scholar collaborators, network resilience and dependence on star collaborators, network clustering, and network assortativity by number of collaborators.

Motivated by an intention to remedy current complications with Dutch terminology concerning informatics, the term informaticology is positioned to denote an academic counterpart of informatics where informatics is conceived of as a container for a coherent family of practical disciplines ranging from computer engineering and software engineering to network technology, data center management, information technology, and information management in a broad sense. Informaticology escapes from the limitations of instrumental objectives and the perspective of usage that both restrict the scope of informatics. That is achieved by including fiction science in informaticology and by ranking fiction science on equal terms with computer science and data science, and framing (the study of) game design, evelopment, assessment and distribution, ranging from serious gaming to entertainment gaming, as a chapter of fiction science. A suggestion for the scope of fiction science is specified in some detail. In order to illustrate the coherence of informaticology thus conceived, a potential application of fiction to the ontology of instruction sequences and to software quality assessment is sketched, thereby highlighting a possible role of fiction (science) within informaticology but outside gaming.

The paper citation network is a traditional social medium for the exchange of ideas and knowledge. In this paper we view citation networks from the perspective of information diffusion. We study the structural features of the information paths through the citation networks of publications in computer science, and analyze the impact of various citation choices on the subsequent impact of the article. We find that citing recent papers and papers within the same scholarly community garners a slightly larger number of citations on average. However, this correlation is weaker among well-cited papers implying that for high impact work citing within one's field is of lesser importance. We also study differences in information flow for specific subsets of citation networks: books versus conference and journal articles, different areas of computer science, and different time periods.; Comment: long version of poster published at ICWSM 2009

The strict globular $\omega$-categories formalize the execution paths of a parallel automaton and the homotopies between them. One associates to such (and any) $\omega$-category $\C$ three homology theories. The first one is called the globular homology. It contains the oriented loops of $\C$. The two other ones are called the negative (resp. positive) corner homology. They contain in a certain manner the branching areas of execution paths or negative corners (resp. the merging areas of execution paths or positive corners) of $\C$. Two natural linear maps called the negative (resp. the positive) Hurewicz morphism from the globular homology to the negative (resp. positive) corner homology are constructed. We explain the reason why these constructions allow to reinterprete some geometric problems coming from computer science.; Comment: 54 pages, 1 eps figure, LaTeX2e ; v2 construction of negative and positive Hurewicz morphisms added, corrected reference ; v3 reorganized paper for a better understanding ; v4 final version to appear in Mathematical Structure in Computer Science ; v5 last minute correction (very minor changes)

The influence of Alfred Tarski on computer science was indirect but significant in a number of directions and was in certain respects fundamental. Here surveyed is the work of Tarski on the decision procedure for algebra and geometry, the method of elimination of quantifiers, the semantics of formal languages, modeltheoretic preservation theorems, and algebraic logic; various connections of each with computer science are taken up.

Globalization and the world wide web has resulted in academia and science being an international and multicultural community forged by researchers and scientists with different ethnicities. How ethnicity shapes the evolution of membership, status and interactions of the scientific community, however, is not well understood. This is due to the difficulty of ethnicity identification at the large scale. We use name ethnicity classification as an indicator of ethnicity. Based on automatic name ethnicity classification of 1.7+ million authors gathered from Web, the name ethnicity of computer science scholars is investigated by population size, publication contribution and collaboration strength. By showing the evolution of name ethnicity from 1936 to 2010, we discover that ethnicity diversity has increased significantly over time and that different research communities in certain publication venues have different ethnicity compositions. We notice a clear rise in the number of Asian name ethnicities in papers. Their fraction of publication contribution increases from approximately 10% to near 50% from 1970 to 2010. We also find that name ethnicity acts as a homophily factor on coauthor networks, shaping the formation of coauthorship as well as evolution of research communities.; Comment: 11 pages...

The best way to understand complex data structures or algorithm is to see them in action. The present work presents a new tool, especially useful for students and lecturers in computer science. It is written in Java and developed at Bordeaux University of Sciences and Technology. Its purposes is to help students in understanding classical algorithms by illustrating them in different ways: graphical (animated), formal, and descriptive. We think that it can be useful to everyone interested in algorithms, in particular to students in computer science that want to beef up their readings and university lecturers in their major effort to enhance the data structures and algorithms course. The main new thing of this tool is the fact of making it possible to the user to animate their own algorithms.

We describe a framework in which to consider designing an entire course for Computer Science majors that covers both technical communications as well as more general communication issues. By utilizing abstraction, we’re able to fashion a framework that allows instructors to design specific course elements that meet their needs or priorities. We take advantage of many other efforts reported upon in the past that discuss processes that students can follow in developing effective communication artifacts, blend writing or speaking assignments into individual courses, or talk about communication-intensive courses.; © ACM, 2006.

Our contention is that there now exists a considerable body of lab exercises that may be used in conjunction with introductory courses. There are fewer models available for instructors of more advanced programming courses, especially those courses which attempt to introduce students to current practices in software engineering. In this paper, we report on our experiences in building a second-year programming course that includes a significant lab and project component. These labs and projects are the vehicle we use to introduce students to the world of professional practice in software development.; © ACM, 1994. This is the author's version of the work.

In Teaching Degree courses in Brazil, the internship intends to complement the student’s graduation process, considering this field of work as an object of investigation and critical reflection on the environment which is around it. However, when it is related to Teaching Degree in Computer Science which forms educators to this area, some difficulties preclude the achievement of the internship in its fullness due to the absence of educational policies which may establish the performance of these teachers. Despite the incentive to actions, which involve the teaching of Computer Science in basic education in Brazil, Computer Science does not make part of any curriculum in schools. Trying to encourage this dialogue, this paper presents part of the scenario of Computer Science education and of the internship’s activities in Teaching Degree courses, showing its organizational structure and its directions of activities that provide experiences with teaching. The research also represents the challenges and the lessons learned while conducting internship disciplines in a specific course.
