Certificates of non-negativity are fundamental tools in optimization. A “certificate” is generally understood as an expression that makes the non-negativity of the function in question evident. Some classical certificates of non-negativity are Farkas Lemma and the S-lemma. The lift-and-project procedure can be seen as a certificate of non-negativity for affine functions over the union of two po...

Abstract This paper argues that the operative force in Luke’s parable of The Rich Fool is negativity. Moreover, negativity as common Lukan parables status reversals. As warns against securing future, this reads Lee Edelman’s No Future: Queer Theory and Death Drive to show how negativity, towards reproductive futurism particular, activates pessimism. pessimism grounded crucifixion not resolved r...

We argue that the political effects of negativity bias are narrower than Hibbing et al. suggest. Negativity bias reliably predicts social, but not economic, conservatism, and its political effects often vary across levels of political engagement. Thus the role of negativity bias in broad ideological conflict depends on the strategic packaging of economic and social attitudes by political elites.

Based on data from a sample of 120 first-generation Mexican immigrant couples collected at the start of the Great Recession in the United States, this study tested an actor-partner interdependence mediation model (APIMeM) in which spouses' perceptions of stress related to economic pressure and cultural adaptation were linked to their own and their partners' reports of marital satisfaction throu...

Feedback negativity is a negative component of the event-related brain potential observed 250-300 ms after feedback stimuli. The present study investigated the effects of value (correct or incorrect) and reward magnitude (no, small or large) on feedback negativity and P300. Feedback negativity was larger after incorrect feedback than after correct feedback, irrespective of reward magnitude. In ...

In order to advance our understanding of the etiology of individual differences in child maladjustment (i.e., conduct and emotional problems), we tested hypotheses about the statistical interactions between child temperament and two aspects of the family environment: maternal negativity and positivity, and household chaos (e.g., crowding, noise, lack of routines). Mothers (n = 149) reported on ...

OBJECTIVE The mismatch negativity, a negative component in the auditory event-related potential, is thought to index automatic processes involved in sensory or echoic memory. The authors' goal in this study was to examine the topography of auditory mismatch negativity in schizophrenia with a high-density, 64-channel recording montage. METHOD Mismatch negativity topography was evaluated in 23 ...

Negativity in election campaign matters. To what extent can the content of social media posts provide a reliable indicator candidates' negativity? We introduce and critically assess an automated classification procedure that we trained to annotate more than 16,000 tweets candidates competing 2018 Senate Midterms. The algorithm is able identify presence political attacks (both general, specifica...
