BACKGROUND A method of occupational physical exposure assessment is needed to improve analyses using large data sets (e.g., national surveys) that provide only job title/category information as a proxy for exposure. METHODS Five ergonomic experts rated and arrived at consensus ratings for job categories used in the Third National Health and Nutrition Examination Survey. Interrater agreement w...

Asymmetric volatility refers to the stylized fact that stock volatility is negatively correlated to stock returns. Traditionally, this phenomenon has been explained by the financial leverage effect. This explanation has recently been challenged in favor of a risk premium based explanation. We develop a new, unlevering approach to document how well financial leverage, rather than size, beta, boo...

Recent developments in network theory have allowed for the study of the structure and function of the human brain in terms of a network of interconnected components. Among the many nodes that form a network, some play a crucial role and are said to be central within the network structure. Central nodes may be identified via centrality metrics, with degree, betweenness, and eigenvector centralit...

Choosing the financial supply is one of the most important decisions for providing optimal structure that can be effective for firm value and stocks market of companies. Therefore, marketing as one of the abilities of the firm can be effective on firm function. The purpose of this research is studying the role of marketing intensity on the relation of financial leverage and firm function in Com...

We propose Deep Optimistic Linear Support Learning (DOL) to solve highdimensional multi-objective decision problems where the relative importances of the objectives are not known a priori. Using features from the high-dimensional inputs, DOL computes the convex coverage set containing all potential optimal solutions of the convex combinations of the objectives. To our knowledge, this is the fir...

The impact of financial leverage on firm investment is one of the most important issues in corporate finance. Debt overhang reduces the incentives of shareholder–management coalition in controlling the firm to invest in positive net-present-value investment opportunities.

We previously reported that the peptide antibiotic, amphomycin, inhibited the transfer of mannose from GDP-[‘4C]mannose and GlcNAc from UDP-[3H]GlcNAc to the lipid-linked saccharides by enzyme preparations of pig aorta (Kang, M. S., Spencer, J. P., and Elbein, A. D. (1978) Biochem. Biophys. Res. Commun. 82,568-574). With the particulate enzyme, the transfer of mannose from GDP-[‘*C)mannose to m...
