Efficient C−B Bond Formation Promoted by N-Heterocyclic Carbenes: Synthesis of Tertiary and Quaternary B-Substituted Carbons through Metal-Free Catalytic Boron Conjugate Additions to Cyclic and Acyclic α,β-Unsaturated Carbonyls

Abstract: Metal-free nucleophilic activation of a B−B bond has been exploited in the development of a highly efficient method for conjugate additions of commercially available bis(pinacolato)diboron to cyclic or acyclic α,β-unsaturated carbonyls. The reactions are readily catalyzed by a simple N-heterocyclic carbene (NHC) present at 2.5−10 mol %. A variety of cyclic and acyclic unsaturated ketones and esters can serve as substrates. The transformations deliver β-boryl carbonyls bearing tertiary or quaternary B-substituted carbons in up to >98% yield. Preliminary studies indicate that although related Cu−NHC-catalyzed reactions are equally efficient, the metal-free variant is more functional-group-tolerant; in contrast to the Cu-catalyzed reactions, the metal-free processes proceed readily in the presence of a terminal alkyne and do not promote concomitant diboration of an aldehyde. Representative functionalization of the resulting boron enolates demonstrates the strong influence of the Lewis acidic B atom of the β-...

The Impact of Detention and Deportation on Latino Immigrant Children and Families: A Quantitative Exploration

Abstract: Children of Latino immigrants, many of whom live in “mixed-status” families, are a rapidly growing group in the United States. It is widely accepted that their development is affected by multiple a...

Social class and mental illness reconsidered: the role of economic stress and social support.

Abstract: Several bodies of research are reviewed for their contributions to defining the relationship of individual psychological disorder to social structure and process. The specific problem addressed is the relationship of social class to psychological impairment and its mediation. The generic problem is one of locating psychological processes and individual behavior within a societal framework. Recent work focusing on the effects of economic change and unemployment on psychological functioning is examined in relation to studies of the support characteristics of families and social networks pertinent to psychological well-being. An integration of this literature is presented based on the interdependency of stress and support variables and is, in turn, employed in a conceptualization of the relationship between social class and psychological disorder. It is argued that stress and support factors are systematically organized within classes at several levels of analysis and constitute critical conditions of class membership related to psychological functioning.

The Informational Efficiency of the Corporate Bond Market: An Intraday Analysis

Abstract: Using a unique dataset including daily and hourly high yield bond transactions prices, we examine the informational efficiency of the corporate bond market relative to the market for the underlying stock. In contrast to previous research utilizing weekly or monthly dealer quotes, we find that stocks do not lead bonds in reflecting firm specific information. We further consider the impact of firm specific information on corporate bond prices by examining price behavior around earnings releases and find that this information is quickly incorporated into both bond and stock prices, even at short return horizons. Finally, we find that measures of market quality are no poorer for the bonds in our sample than for the underlying stocks. Our results suggest that the relative informativeness of high yield bond prices is driven largely by the bonds' liquidity rather than the structure of the dealer market for corporate bonds.

Relating Brandand Customer Perspectives on Marketing Management

Abstract: What is the difference between brand equity and customer equity? Does the distinction matter? Is there a difference between the firm’s brand asset and customer asset? What are the implications of taking a brand perspective versus a customer perspective when designing and implementing marketing programs? The objective of this article is to examine these two perspectives in depth so that researchers and managers can improve their understanding and use of customer and brand perspectives on marketing. The authors seek to determine the relationship between the two assets and perspectives in terms of similarities and differences. They examine the development of customer and brand perspectives and describe how each adds value to the firm and to the customer. Subsequently, they delineate possible approaches for measuring marketing assets. They discuss key issues researchers and practitioners should consider in managing marketing assets, particularly for multibrand companies. They conclude by suggesting future res...
