The now recognized core construct of psychological capital, or simply PsyCap, draws from positive psychology in general and positive organizational behavior (POB) in particular. The first-order positive psychological resources that make up PsyCap include hope, efficacy, resilience, and optimism, or the HERO within. These four best meet the inclusion criteria of being theoryand research-based, p...

Although intuitive and predicted by the broaden-and-build theory of positive emotions, previous research has not seriously tested the idea that positive moods can cause sociability. The authors developed a new measure to assess preferences for social (vs. nonsocial) situations, carefully controlling for the fact that social situations are, on average, also more pleasant. Across two additional e...

Children face an enormously difficult task in learning their native language. It is widely believed that they do not receive or make little use of negative evidence (Marcus, 1993), and yet it has been proven that many classes of languages less powerful than natural languages cannot be learned in the absence of negative evidence (Gold, 1964). In this paper we present an approach to learning good...

Why can't we say the asleep cat? There is a class of adjectives in English, all of which start with a schwa (e.g. afraid, alone, asleep, away, etc.), that cannot be used attributively in a prenominal position. A frequently invoked strategy for the acquisition of such negative constraints in language is to use indirect negative evidence. For instance, if the learner consistently observes paraphr...

An antiemetic action is claimed among other uses for acupuncture (ACP), and several antiemetic ACP points are described in textbooks. The most accessible of these is P6, so called because it is on the pericardial meridian. This is also known as Neiguan (Nei-kuan) or G-Jo point no. 10, and the simplest description of locating it is the width of two thumbs above the distal crease on the inner wri...

Cost-effectiveness analysis (CEA) offers decision makers a structured, rational approach with which to improve the return on resources expended. But decades after its widespread promotion to the medical community, policy makers in the United States remain reluctant to use the approach formally. Indeed, the resistance to economic evidence in the United States in an era of evidence-based medicine...

Modern clinical practice relies on evidence-based medicine (EBM) and evidence-based guidelines (EBGs). The critical evaluation of EBGs value is therefore an essential step to further improve clinical practice. In our opinion, correlating levels of evidence and grades of recommendation can be an easy tool to quickly display internal consistence of EBGs.
