An analysis of IS technical career paths and job satisfaction
Authors: Catherine M. Ridings, Lauren B. Eder
Venue: ACM SIGCPR Computer Personnel (1999)

Technical career paths have been implemented in Information Systems (IS) departments to address the career development needs of employees whose career aspirations are not met by the traditional managerial career path. Understanding how to meet the needs of the technically oriented IS employee is important to IS career planning and development. Much has been written in both academic and popular literature about what composes a successful technical career path. Equity theory has been used in much of the existing research on technical career paths. This literature suggests that a successful technical career path should provide equitable rewards to those of a managerial career path. The present research establishes scales for four "key success factors" - equitable compensation, career path status, decision making influence, and career planning tool availability --- and examines the relationship of perceived equity of these factors to job satisfaction. Job satisfaction is relevant to an organization because it has been shown to be related to motivation to stay in an organization and organizational commitment. IS personnel on a technical career path were surveyed with regard to their equity perceptions and job satisfaction. Scales for the perception of equity for all four success factors were established. Data analysis showed that only the perception of equity of career planning tool availability is related to job satisfaction for these employees. Implications for management and areas for further research are discussed.

XMLTM: efficient transaction management for XML documents
Authors: Torsten Grabs, Klemens Böhm, Hans-Jörg Schek
Venue: Proceedings of the eleventh international conference on Information and knowledge management (2002)

A common approach to storage and retrieval of XML documents is to store them in a database, together with materialized views on their content. The advantage over "native" XML storage managers seems to be that transactions and concurrency are for free, next to other benefits. But a closer look and preliminary experiments reveal that this results in poor performance of concurrent queries and updates. The reason is that database lock contention hinders parallelism unnecessarily. We therefore investigate concurrency control at the semantic, i.e., XML level and describe a respective transaction manager XMLTM. It features a new locking protocol DGLOCK. It generalizes the protocol for locking on directed acyclic graphs by adding simple predicate locking on the content of elements, e.g., on their text. Instead of using the original XML documents, we propose to take advantage of an abstraction of the XML document collection known as DataGuides. XMLTM allows to run XML processing at the underlying database at low ANSI isolation degrees and to release database locks early without sacrificing correctness in this setting. We have built a complete prototype system that is implemented on top of the XML Extender for IBM DB2. Our evaluation shows that our approach consistently yields performance improvements by an order of magnitude. We stress that our approach can also be implemented within a native XML storage manager, and we expect even better performance.
Approximate medial axis as a voronoi subcomplex
Authors: Tamal K. Dey, Wulue Zhao
Venue: Proceedings of the seventh ACM symposium on Solid modeling and applications (2002)

Medial axis as a compact representation of shapes has evolved as an essential geometric structure in a number of applications involving 3D geometric shapes. Since exact computation of the medial axis is difficult in general, efforts continue to approximate them. One line of research considers the point cloud representation of the boundary surface of a solid and then attempts to compute an approximate medial axis from this point sample. It is known that the Voronoi vertices converge to the medial axis for a curve in 2D as the sample density approaches infinity. Unfortunately, the same is not true in 3D. Recently, it is discovered that a subset of Voronoi vertices called poles converge to the medial axis in 3D. However, in practice, a continuous approximation as opposed to a discrete one is sought. Recently few algorithms have been proposed which use the Voronoi diagram and its derivatives to compute this continuous approximation. These algorithms are scale or density dependent. Most of them do not have convergence guarantees, and one of them computes it indirectly from the power diagram of the poles. In this paper we present a new algorithm that approximates the medial axis straight from the Voronoi diagram in a scale and density independent manner with convergence guarantees. The advantage is that, unlike for others, one does not need to fine tune any parameter for this algorithm. We present extensive experimental evidences in support of our claims.
A precedence-based approach for proactive control in software process modelling
Authors: Josep M. Ribó, Xavier Franch
Venue: Proceedings of the 14th international conference on Software engineering and knowledge engineering (2002)

We present the proactive behavioural features of PROMENADE, a process modelling language for formalizing the construction of software process models. PROMENADE aims at improving expressiveness, standardization, flexibility and reuse in software process modelling. In this article we focus on expressiveness, which is achieved by means of a declarative (instead of imperative) proactive control-flow based on precedence relationships. Different families of such precedences have been defined within the language (namely, basic, derived and dynamic). Also, PROMENADE provides (1) a comprehensive parameter task-binding mechanism to keep track of document-flow between tasks; (2) a high level notation to define new precedence relationships, which may be used to tailor the language to the specific needs of each user and process; (3) the definition of flexible models by leaving some parts undefined until enactment time. The specific concepts necessary to model a software process are defined and integrated into the UML metamodel. The extended metamodel is converted into a UML profile using stereotypes, constraints and tag definitions.

Distribution of cycle lengths in graphs
Authors: Genghua Fan
Venue: Journal of Combinatorial Theory Series B (2002)

Bondy and Vince proved that every graph with minimum degree at least three contains two cycles whose lengths differ by one or two, which answers a question raised by Erdös. By a different approach, we show in this paper that if G is a graph with minimum degree δ(G) ≥ 3k for any positive integer k, then G contains k+1 cycles C0, C1, ... Ck such that k+1 < |E(C0)| < |E(C1)| < ... < |E(Ck)|, |E(Ci)|- |E(Ci-1)|= 2, i ≤ i ≤ k - 1, and 1 ≤ |E(Ck)|-|E(Ck-1)| ≤ 2, and furthermore, if δ(G) ≥ 3k + 1, then |E(Ck)|-|E(Ck-1)|= 2. To settle a problem proposed by Bondy and Vince, we obtain that if G is a nonbipartite 3-connected graph with minimum degree at least 3k for any positive integer k, then G contains 2k cycles of consecutive lengths m, m+1, ..., m+2k-1 for some integer m ≥ k+2.

A training program for information technology organizations transitioning to enterprise-wide client/server computing
Authors: Stuart D. Galup
Venue: ACM SIGCPR Computer Personnel (1999)

Islands of information are still common place in many organizations. Yet, the growth of electronic-business and the increased use of enterprise resource planning software suggest the transition to enterprise-wide information systems will be one of the most important challenges facing information technology organizations during this millenium.Facing a major "year 2000" software rewrite during the beginning of 1990, the organization in this case study decided to revamp their information systems using client/server technologies and establish a new way of doing business (PCISS Board Minutes, 1995). Their plan was to share data and software across organizational boundaries in an effort to reduce software development costs and increase data quality (PCTTP, 1995).Transitioning to this new paradigm required rethinking how the information technology organization was organized and managed. It also required updating the employee's skills (Lee, Trauth, & Farwell, 1995) and the building of team-based structures (DeSanctis & Jackson, 1994). This case study discusses the training program used to transition the employees to an enterprise-wide client/server computing model, a strategy that supports adult learning issues and fosters the creation of cross-functional teams.
World-Class Accounting and Finance
Authors: C. J. McNair
Venue:  (1993)

:For a long time, nonfinancial managers have viewed the financial and accounting function as a hands-off area, segregating it from day-to-day manufacturing processes and performance goals. But now, as author C. J. McNair points out, it is one of the keys to staying competitive. World-Class Accounting and Finance explains how the financial function developed its existing focus and what types of changes are being made in leading edge firms today. Most important, the book reveals how financial information systems can be transformed into a value-adding tool that supports continuous improvement, measurement systems, and management decision making. McNair outlines basic and advanced accounting principles in an easy-to-understand format. She demonstrates how, through financial information systems, financial and nonfinancial managers can develop cost-effective strategies and become more involved in the improvement of day-to-day functions. This unique guide provides a look at strategic, planning, and behavioral aspects of the financial function, and an analysis of how to effectively integrate it with other types of performance measurement systems; methods to successfully balance the traditional reporting and recordkeeping functions of accounting with value-added, customer-driven procedures; a thorough examination of financial numbers and why they are useful for managing overhead, analyzing strategy, evaluating performance, and more; and a comprehensive glossary of financial, accounting, and manufacturing concepts for quick, easy reference. Financial information systems, like every other organizational function, must be evaluated and aligned with continuous improvement and quality goals. World-Class Accounting and Finance is for all managers who want to understand and maximize their organization's financial information systems to satisfy the needs of internal and external customers, build productivity, and establish a long-term competitive edge.

Adaptive Reduced-Order Controllers for a Thermal Flow System Using Proper Orthogonal Decomposition
Authors: S. S. Ravindran
Venue: SIAM Journal on Scientific Computing (2001)

An adaptive reduced-order controller design is presented for flow control using proper orthogonal decomposition (POD). In reduced-order controller design, the idea is to start with an ensemble of data obtained from numerical simulation of the underlying partial differential equations (PDEs). POD is then used to obtain a reduced set of basis functions which is then used to derive a reduced-order model of the PDEs via Galerkin projection. This reduced-order model allows us to derive a reduced-order controller. However, it is not clear, a priori, what is the best way to obtain an ensemble of data that would give basis functions that represent the influence of the control action on the system. In this paper we explore an adaptive procedure for reduced-order controller design that improves the reduced-order model by successively updating the ensemble of data during the optimization iterations. We illustrate this method on a control problem in thermal flow system modeled by a thermally coupled Navier--Stokes equations. Numerical results are presented for a vorticity regulation problem in fluid flows using boundary temperature as control mechanism. Through our numerical experiments we demonstrate the feasibility and applicability of the adaptive reduced-order controllers.

Sparse sets and collapse of complexity classes
Authors: Vladimír Glasnak
Venue: Information and Computation (2001)

In this paper a new upward separation technique is developed. It is applied to prove that for a class of functions F a separation DTIME (F) NTIME (F) can be characterized by the existence of (not only polynomially) sparse sets in certain complexity classes. As a consequence, a solution of an open question of J. Hartmanis (1983, Inform. Process. Lett. 16, 55-60) is obtained: There is an no log n-sparse set in NP-P iff ). Further we prove that there is an no (log n)-sparse set in NP-coNP iff. The technique also allows us to characterize the existence of sets of different densities in NP-P by the existence of slightly denser sets in NTIME (F)-DTIME (F) for certain classes of functions F. For example, there is an no (log n)-sparse set in NP-P iff there is an n0 ((log n)3) -sparse set in. The end of the paper is devoted to limitations of the technique. Copyright 2001 Academic Press.
