The Attributional Double Standard : Actor-Observer Differences in Predicting the Relationship Between Attitudes and Behaviors

It was hypothesized that subjects who took the role of interaction observers ration than actors would predict a closer relationship between attitudes and behaviors and would report greater confidence in behavioral predictions derivable from an actor\u27s attitude statements. One hundred sixty-eight subjects assumed the role of either actor or observer in scenarios of group interactions in which a central person made a statement about a particular attitude object. As predicted, subjects in the observer role reported that specific future behaviors (e.g., loaning money, helping to study for a test) had a greater likelihood of occurrence following an attitude statement (e.g., I like Pat ) than did subjects in the actor role, and observers were more confident than actors in these predictions. In addition, the favorability of the attitude statement was directly related to the strength of predictions, and the central person\u27s familiarity with the audience was directly related to confidence in predictions. Observers apparently view attitude statements as reliable indications of internal dispositions that serve as a potential cause of subsequent behaviors, while actors view attitude statements as tenuous orientations that can be modified in accord with future situational contingencies

Self-Presentational Determinants of Sex Differences in Leadership Behavior

Men and women placed in leadership positions communicated information about their skills and abilities to their subordinates. Although leaders’ perceptions of their abilities, group members’ knowledge of their leader’s abilities, and the specific skills needed by the leader were all manipulated in the experimental setting, self-presentations of ability were primarily determined by sex role stereotypes rather than by situational factors. Results indicated that (1) male leaders emphasized their social influence and task abilities; (2) female leaders emphasized their interpersonal, socioemotional abilities; and (3) group members felt task ability, as compared to interpersonal ability, was a far more important skill for a leader to possess. It was concluded that sex differences in male and female leadership behavior may be due to self-presentational conformity to sex roles, and that this conformity enhances males’ leadership effectiveness while detracting from females’ leadership effectiveness

The principles of communicative language use

The paper aims to overview some typical principles of communicative language use in a cognitive pragmatic approach applying a reductionist method in order to demonstrate that the well-known principles can be reduced to a very general rationality (economy) principle. After briefly reviewing the principles the paper re-evaluates them and provides a new classification of them relying on the definition of ostensive-inferential communication. The principles which can be divided into rationality and interpersonality principles are really principles of effective information transmission on objects and selves. They refer to two kinds of language use: informative and communicative ones. The only principles valid for only communicative language use are the communicative principle of relevance and the principle of communicative intention suggested in the present article. Finally, the paper reduces all rationality and interpersonality principles to a very general rationality principle, i.e., the cognitive principle of relevance

Mapping Hansard Impression Management Strategies through Time and Space

Impolite behaviour is thought to be easier to investigate than polite or politic behaviour in diachronic contexts, because of attracting more evaluative comment. But an approach based on such metapragmatic commentary can miss a lot of facework strategies in contexts such as the UK parliament (modern and historical). In this paper, I draw on Historic Hansard datasets (1812–2003) to demonstrate how a (semi)automatic method involving contiguous searches of two-to-four features can better reveal the nuances of these MPs’ facework strategies than a focus on metapragmatic terms has afforded hitherto. The (semi)automatic method uses the recently created Historic Thesaurus Semantic Tagger (HTST) to search for meaning constellations (Archer and Malory 2017). Meaning constellations relating to facework are made up of sequences of semantic fields and/or parts-of-speech which, when organised in certain ways, achieve im/politeness, politic behaviour, strategic ambiguity, a combination of face enhancement and face threat, etc. This paper discusses a number of these meaning constellations, with a particular focus on those which engage in both face enhancement and face aggravation simultaneously (whilst nonetheless avoiding the label, “unparliamentary language”)

Search for dark matter produced in association with bottom or top quarks in √s = 13 TeV pp collisions with the ATLAS detector

A search for weakly interacting massive particle dark matter produced in association with bottom or top quarks is presented. Final states containing third-generation quarks and miss- ing transverse momentum are considered. The analysis uses 36.1 fb−1 of proton–proton collision data recorded by the ATLAS experiment at √s = 13 TeV in 2015 and 2016. No significant excess of events above the estimated backgrounds is observed. The results are in- terpreted in the framework of simplified models of spin-0 dark-matter mediators. For colour- neutral spin-0 mediators produced in association with top quarks and decaying into a pair of dark-matter particles, mediator masses below 50 GeV are excluded assuming a dark-matter candidate mass of 1 GeV and unitary couplings. For scalar and pseudoscalar mediators produced in association with bottom quarks, the search sets limits on the production cross- section of 300 times the predicted rate for mediators with masses between 10 and 50 GeV and assuming a dark-matter mass of 1 GeV and unitary coupling. Constraints on colour- charged scalar simplified models are also presented. Assuming a dark-matter particle mass of 35 GeV, mediator particles with mass below 1.1 TeV are excluded for couplings yielding a dark-matter relic density consistent with measurements

Nutritionally Enhanced Staple Food Crops

Crop biofortification is a sustainable and cost-effective strategy to address malnutrition in developing countries. This review synthesizes the progress toward developing seed micronutrient-dense cereals and legumes cultivars by exploiting natural genetic variation using conventional breeding and/or transgenic technology, and discusses the associated issues to strengthen crop biofortification research and development. Some major QTL for seed iron and zinc, seed phosphorus, and seed phytate in common bean, rice,J;md wheat have been mapped. An iron reductase QTL associated with seed-iron ~QTL is found in common bean where the genes coding for candidate enzymes involved in phytic acid synthesis have also been mapped. Candidate genes for Ipa co segregate with mutant phenotypes identified in rice and soybean. The Gpe-B1 locus in wild emmer wheat accelerates senescence and increases nutrient remobilization from leaves to developing seeds, and another gene named TtNAM-B1 affecting these traits has been cloned. Seed iron-dense common bean and rice in Latin America; seed iron-dense common bean in eastern and southern Africa;....
