Soft Regulators, Tough Judges

Instant tough bonding of hydrogels for soft machines and electronics

Introducing methods for instant tough bonding between hydrogels and antagonistic materials-from soft to hard-allows us to demonstrate elastic yet tough biomimetic devices and machines with a high level of complexity. Tough hydrogels strongly attach, within seconds, to plastics, elastomers, leather, bone, and metals, reaching unprecedented interfacial toughness exceeding 2000 J/m2. Healing of se...

Tough Private Lenders Competing Against Soft State Banks

In many economies, small and medium-sized firms have no direct access to the financial markets but depend on bank loans. In the market for bank loans, competition is often distorted by state banks enjoying lower funding costs than private banks due to a state guarantee on their liabilities. In this paper, we argue that if the state bank’s guarantee is tied to an obligation to renegotiate loans ...

Evaluating Judges

Much of the interest in empirical studies of judges lies in the comparison of actual to ideal behavior. When we ask what makes a good judge or whether a judge rightly decided a case, we implicitly compare the judge's decisions to a normative standard. In some instances, the content of the normative standard is uncontroversial and its application straightforward. Hence, a trial judge who sentenc...

Esthetic preferences of European American, Hispanic American, Japanese, and African judges for soft-tissue profiles.

INTRODUCTION Our objectives were to determine whether observer and patient sex and race or ethnicity determine esthetic preferences for lip positions. METHODS Four independent panels each consisting of 30 lay judges viewed pretreatment silhouette profiles of 10 European American, 10 Japanese, and 10 African American Angle Class I and Class II orthodontic patients. The panels included European...
