Tree-Based Algorithm For Stable And Efficient Data Clustering, Hasan Aljabbouli, Abdullah Albizri, Antoine Harfouche

Department of Information Management and Business Analytics Faculty Scholarship and Creative Works

The K-means algorithm is a well-known and widely used clustering algorithm due to its simplicity and convergence properties. However, one of the drawbacks of the algorithm is its instability. This paper presents improvements to the K-means algorithm using a K-dimensional tree (Kd-tree) data structure. The proposed Kd-tree is utilized as a data structure to enhance the choice of initial centers of the clusters and to reduce the number of the nearest neighbor searches required by the algorithm. The developed framework also includes an efficient center insertion technique leading to an incremental operation that overcomes the instability problem of the K-means …

Project Foresight: A Ten-Year Retrospective, Paul J. Speaker, Max M. Houck

Faculty & Staff Scholarship

Project FORESIGHT is a business-guided self-evaluation of forensic science laboratories across the globe. The participating laboratories represent metro, regional, state, and national agencies. Economics, accounting, finance, and forensic faculty provide assistance, guidance, and analysis. Laboratories participating in Project FORESIGHT have developed standardized definitions for metrics to evaluate work processes, linking financial information to work tasks, and functions. Laboratory managers can then assess resource allocations, efficiencies, and value of services—the mission of Project FORESIGHT is to measure, preserve what works, and change what does not.

The benchmark data for the 2018-2019 performance period includes laboratory submissions for a variety of fiscal …

Family Ownership And Corporate Environmental Responsibility: The Contingent Effect Of Venture Capital And Institutional Environment, Zhu Zhu, Feifei Lu

Department of Management Faculty Scholarship and Creative Works

As scholars and policy makers pay more attention to the environmental impact of economic activities, more focus has been placed on the corporate environmental responsibility (CER) of family firms, which accounts for the majority of businesses in both developed and developing countries. Using a sample of 4714 private enterprises across 23 provinces in China, the current study examines the effect of family ownership on CER investment, as well as the moderating effects of venture capital investment and local institutional development. Results show that concentrated family ownership leads to lower CER spending, however, when venture capital investment comes from developed markets, …

Managerial Attributes, Incentives, And Performance, Zhichuan Li, Jeffrey L. Coles

Business Publications

We examine the relative importance of observed and unobserved firm- and manager-specific heterogeneities in determining executive compensation incentives and firm policy, risk, and performance. First, we decompose executive incentives into time-variant and time-invariant firm and manager components. Manager fixed effects supply 73% (60%) of explained variation in delta (vega). Second, controlling for manager fixed effects alters parameter estimates and corresponding inference on observed firm and manager characteristics. Third, larger CEO delta (vega) fixed effects predict better firm performance (riskier corporate policies and higher firm risk). These results suggest that the delta (vega) fixed effect captures managerial ability (risk aversion).
