Conglomerate masses

Melanoptysis as a complication of fibreoptic bronchoscopy.

The case is presented of a coal miner with bilateral masses of progressive massive fibrosis, who developed acute cavitation following fibreoptic bronchoscopy and biopsies. Indeed, immediately upon bronchoscopy with transbronchial biopsy, there was expectoration of abundant melanoptysis. Three days later, the chest radiograph showed a cavity and the patient again coughed up black material, in th...

Computed tomography features of liparitosis: a pneumoconiosis due to amorphous silica.

The purpose of this study was to describe the radiological features of pleural, parenchymal and mediastinal damage due to occupational inhalation of pumice. In total, 31 workers were evaluated for annual follow-up. Spiral computed tomography (CT) was obtained in the three patients with evident parenchymal abnormalities at chest radiograph. High-resolution computed tomography (HRCT) was performe...

Running Head: RESILIENCE: DISTINCT CONSTRUCT OR CONGLOMERATE? 1 Resilience: Distinct Construct or Conglomerate of Existing Traits?

The h - index of a conglomerate Ronald Rousseau

Conglomerates are generalized frameworks for informetric research. In this article, the h-index of a conglomerate is defined and it is shown how this construction generalizes the standard definition of the h-index. It is further shown how non-trivial constructions, such as Prathap’s h-indices, fit well into a conglomerate framework. An example illustrates the use of the conglomerate framework.

Determinants of conglomerate and predatory acquisitions: evidence from the 1960s

We estimate continuous-time event-history models of the acquisition of conglomerate vs. non-conglomerate and predatory vs. friendly acquisitions among the 1962 Fortune 500 between January, 1963, and December, 1968. Our analysis of predatory acquisitions reveals that there were strong disciplinary motivations for these acquisitions in the 1960s. Q ratios were, by a large margin, the most importa...
