Nanocrystalline particles of Cerium Oxide (CeO2) have been prepared by the chemical precipitation method using Cerium nitrate and Urea with a molar ratio of 1:2. The results revealed that the formation of CeO2 fine particles is influenced by molar ratio of metal nitrates to fuel. Well faceted CeO2 nanoparticles, were synthesized by thermal-assisted dissociation ...

The present study aims to assess the relationship between some corporate factors and managerial entrenchment in companies listed on the Tehran Stock Exchange during 2011-2017. Panel data regression models were used to test the hypotheses. The obtained results indicated that four corporate factors, namely real earnings management, predictable earnings management, institutional ownership, and boa...

Top management turnover can be classified into forced turnover and voluntary turnover. Forced CEO turnover may be triggered by poorer operating performance (Helwege et al. 2012) that fails to meet the expectation of corporate board; this pressure of immediate performance improvement may induce the incoming CEO to engage in earnings management (SAS No.99, AICPA 2002), and in turn increase the li...

This study examines the determinants of non-routine CEO departure in a comprehensive sample of UK listed firms between 1990 and 1995. It looks at whether the Cadbury Report, published in December 1992 has had an impact on the agency problem of managerial entrenchment. I find a strong negative relationship between firm performance and the probability of non-routine CEO departure, with evidence t...

This chapter proposes nonlinear models using artificial neural network models to study the relationship between chief elected official (CEO) tenure and debt. Using Higher Order Neural Network (HONN) simulator, this study analyzes debt of the municipalities as a function of population and CEO tenure, and compares the results with that from SAS. The linear models show that CEO tenure and the amou...

A series of nanostructured Pt-Au/MOx-CeO₂ (M = Mn, Fe, Ti) catalysts were prepared and their catalytic performance for the co-oxidation of carbon monoxide (CO) and hydrogen (H₂) were evaluated at room temperature. The results showed that MOx promoted the CO oxidation of Pt-Au/CeO₂, but only the TiO₂ could enhance co-oxidation of CO and H₂ over Pt-Au/CeO₂. Related characterizations were conducte...

This study focuses on the leadership structure at the very top of a firm. Specifically, it examines how the presence of a COO/president, who is separate from the CEO, affects strategic change and CEO dismissal. With longitudinal data on the tenures of 207 CEOs, results suggest that the presence of a separate COO/president increases the magnitude of strategic change under conditions of low firm ...

Existing research links CEO personality traits to a number of corporate decisions including overinvestment, external acquisitions, and earnings management. These findings raise the question of whether counterparties distinguish between differences in individual CEO behavior, and how they respond to it. We focus on two key counterparties – auditors and credit rating agencies – and examine whethe...

Mesoporous photocatalysts of CeO2/SBA-15 are prepared by two methods of direct synthesis as solvent-usage and solvent-free methods. In solvent-usage method, CeO2/SBA-15 is synthesized in acidic media. While, in solvent-free method, CeO2/SBA-15, has been prepared through the novel path of directly grind cerium salt into the as-prepared samples of SBA-15 occluded ...
