Cluster planning and cluster strategy in regional economic development organizations
… the results of a cross-sectional survey of cluster-based regional economic development efforts in the US In a much cited article from 1990, Levy distinguished between rational model and sales activities in local economic development practice. More recently, the debate around cluster-based …

Bayesian cluster validation
… based on Bayesian principles for validating clusterings and present efficient algorithms for use with centroid or exemplar based clustering solutions. Our framework treats the data as fixed and introduces perturbations into the clustering procedure. In our algorithms, we scale the distances …

Cluster Weather Vanes: Radio Galaxies as Indicators of Galaxy Cluster Dynamics
… of such jets with dynamical features of galaxy cluster media such as winds and shock waves, and to use the recognizable observed features as diagnostic tools when examining real radio sources in clusters to better understand the state of the environment surrounding radio galaxies (RG). We …

Extragalactic Globular Cluster Systems
Das Ziel dieser Dissertation ist die spektroskopische Studie von extragalaktischen Kugelsternhaufensystemen. Ihre Motivation ist das bessere Verstaendnis der Bildung und Entwicklung dieser Kugelsternhaufensysteme und ihrer Wirtsgalaxien. Zu diesem Zweck werden spektroskopische Linienindices des …

On Cluster Robust Models
<p>Cluster robust models are a kind of statistical models that attempt to estimate parameters considering potential heterogeneity in treatment effects. Absent heterogeneity in treatment effects, the partial and average treatment effect are the same. When heterogeneity in treatment effects occurs, …

Categorifications of Cluster Varieties
… varieties whose coordinate rings admit a cluster algebra structure. The presence of a cluster structure has important implications for the geometry of a variety including the existence of canonical linearly independent sets of regular functions. Additionally, methods for studying cluster …

Open cluster groups and complexes
… agreed upon that stars typically form in open clusters and stellar associations, but little is known about the structure of the open cluster system. Do open clusters and stellar associations form isolated or do they prefer to form in groups and complexes? Open cluster groups and complexes could …

Cluster-based find and replace
… option when performing a find and replace: a cluster-based find and replace. Instead of replacing one match at a time or all matches at once, the user can choose to replace a cluster of similar matches. While I hypothesized that a cluster-based find and replace interface would make users …

Cluster-Based Bounded Influence Regression
… outliers. This proposed method blends a cluster analysis phase with a controlled bounded influence regression phase, thereby referred to as cluster-based bounded influence regression, or CBI. Representing the data space via a special set of anchor points, a collection of point-addition …

Searching for Distant Galaxy Clusters : Optical Observations, Cluster Search Algorithms and the Cluster Selection Function
… to construct a statistically significant galaxy cluster sample for galaxy evolution studies using a multi-color classification scheme in the redshift range 0.5 < z < 1.5. After contributing to the survey specifications, tests of the multi-color classification with the observational setup showed …

Ethical Challenges in Cluster Randomized Trials
… Consent in CRTs is associated with smaller cluster sizes, and the use of individual-level experimental and data collection interventions. CRT researchers are most concerned with issues around informed consent, and less concerned with issues related to the analysis of harms and benefits in …
