iPosture: The Size of Electronic Consumer Devices Affects our Behavior

We examined whether incidental body posture, prompted by working on electronic devices of different sizes, affects power-related behaviors. Grounded in research showing that adopting expansive body postures increases psychological power, we hypothesized that working on larger devices, which forces people to physically expand, causes users to behave more assertively. Participants were randomly assigned to interact with one of four electronic devices that varied in size: an iPod Touch, an iPad, a MacBook Pro (laptop computer), or an iMac (desktop computer). As hypothesized, compared to participants working on larger devices (e.g., an iMac), participants who worked on smaller devices (e.g., an iPad) behaved less assertively – waiting longer to interrupt an experimenter who had made them wait, or not interrupting at all

Gendered Races: Implications for Interracial Marriage, Leadership Selection, and Athletic Participation

Six studies explored the overlap between racial and gender stereotypes and the consequences of this overlap for interracial dating, leadership selection, and athletic participation. Two initial studies, utilizing explicit and implicit measures, captured the stereotype content of different racial groups: the Asian stereotype was seen as more feminine whereas the Black stereotype more masculine compared to the White stereotype. Study 3 found that preferences for masculinity versus femininity mediated White participants' attraction to Blacks relative to Asians. Analysis of the 2000 United States Census replicated this pattern with interracial marriages. In Study 5, Blacks were more likely and Asians less likely to be selected for a masculine leadership position compared to Whites. Study 6 analyzed the NCAA Student-Athlete Ethnicity Report and found Blacks were more heavily represented in masculine versus feminine sports relative to Asians. These studies demonstrate that the association between racial and gender stereotypes has important real-world consequences

Aid in the Aftermath of Hurricane Katrina: Inferences of Secondary Emotions and Intergroup Helping

This research examines inferences about the emotional states of ingroup and outgroup victims after a natural disaster, and whether these inferences predict intergroup helping. Two weeks after Hurricane Katrina struck the southern United States, White and non-White participants were asked to infer the emotional states of an individualized Black or White victim, and were asked to report their intentions to help such victims. Overall, participants believed that an outgroup victim experienced fewer secondary, ‘uniquely human’ emotions (e.g. anguish, mourning, remorse) than an ingroup victim. The extent to which participants did infer secondary emotions about outgroup victims, however, predicted their helping intentions; in other words, those participants who did not dehumanize outgroup victims were the individuals most likely to report intentions to volunteer for hurricane relief efforts. This investigation extends prior research by: (1) demonstrating infraglobalhumanization of individualized outgroup members (as opposed to aggregated outgroups); (2) examining infrahumanization via inferred emotional states (as opposed to attributions of emotions as stereotypic traits); and (3) identifying a relationship between infra-humanization of outgroup members and reduced intergroup helping

The Benefit of Power Posing Before a High-Stakes Social Evaluation

The current experiment tested whether changing one‘s nonverbal behavior prior to a high-stakes social evaluation could improve performance in the evaluated task. Participants adopted expansive, open (high-power) poses, or contractive, closed (low-power) poses, and then prepared and delivered a speech to two evaluators as part of a mock job interview, a prototypical social evaluation. All speeches were videotaped and coded for overall performance and hireability, and the potential mediators of speech quality (e.g., content, structure) and presentation quality (e.g., captivating, confident). As predicted, high power posers performed better and were more likely to be chosen for hire, and this relationship was mediated only by presentation quality, not speech quality. Power pose condition had no effect on body posture during the social evaluation, thus highlighting the relationship between preparatory nonverbal behavior and subsequent performance

Status boundary enforcement and the categorization of black–white biracials

Individuals who qualify equally for membership in more than one racial group are not judged as belonging equally to both of their parent groups, but instead are seen as belonging more to their lower status parent group. Why? The present paper begins to establish the role of individual differences and social context in hypodescent, the process of assigning multiracials the status of their relatively disadvantaged parent group. Specifically, in two experiments, we found that individual differences in social dominance orientation—a preference for group-based hierarchy and inequality—interacts with perceptions of socioeconomic threat to influence the use of hypodescent in categorizing half-Black, half-White biracial targets. Importantly, this paper begins to establish hypodescent as a “hierarchy-enhancing” social categorization.Psycholog

Speed breeding is a powerful tool to accelerate crop research and breeding

The growing human population and a changing environment have raised significant concern for global food security, with the current improvement rate of several important crops inadequate to meet future demand1. This slow improvement rate is attributed partly to the long generation times of crop plants. Here, we present a method called ‘speed breeding’, which greatly shortens generation time and accelerates breeding and research programmes. Speed breeding can be used to achieve up to 6 generations per year for spring wheat (Triticum aestivum), durum wheat (T. durum), barley (Hordeum vulgare), chickpea (Cicer arietinum) and pea (Pisum sativum), and 4 generations for canola (Brassica napus), instead of 2–3 under normal glasshouse conditions. We demonstrate that speed breeding in fully enclosed, controlled-environment growth chambers can accelerate plant development for research purposes, including phenotyping of adult plant traits, mutant studies and transformation. The use of supplemental lighting in a glasshouse environment allows rapid generation cycling through single seed descent (SSD) and potential for adaptation to larger-scale crop improvement programs. Cost saving through light-emitting diode (LED) supplemental lighting is also outlined. We envisage great potential for integrating speed breeding with other modern crop breeding technologies, including high-throughput genotyping, genome editing and genomic selection, accelerating the rate of crop improvement

Favouritism: exploring the 'uncontrolled' spaces of the leadership experience

In this paper, we argue that a focus on favouritism magnifies a central ethical ambiguity in leadership, both conceptually and in practice. The social process of favouritism can even go unnoticed, or misrecognised if it does not manifest in a form in which it can be either included or excluded from what is (collectively interpreted as) leadership. The leadership literature presents a tension between what is an embodied and relational account of the ethical, on the one hand, and a more dispassionate organisational ‘justice’ emphasis, on the other hand. We conducted 23 semi-structured interviews in eight consultancy companies, four multinationals and four internationals. There were ethical issues at play in the way interviewees thought about favouritism in leadership episodes. This emerged in the fact that they were concerned with visibility and conduct before engaging in favouritism. Our findings illustrate a bricolage of ethical justifications for favouritism, namely utilitarian, justice, and relational. Such findings suggest the ethical ambiguity that lies at the heart of leadership as a concept and a practice

Effects of antiplatelet therapy on stroke risk by brain imaging features of intracerebral haemorrhage and cerebral small vessel diseases: subgroup analyses of the RESTART randomised, open-label trial

Background Findings from the RESTART trial suggest that starting antiplatelet therapy might reduce the risk of recurrent symptomatic intracerebral haemorrhage compared with avoiding antiplatelet therapy. Brain imaging features of intracerebral haemorrhage and cerebral small vessel diseases (such as cerebral microbleeds) are associated with greater risks of recurrent intracerebral haemorrhage. We did subgroup analyses of the RESTART trial to explore whether these brain imaging features modify the effects of antiplatelet therapy

Cross-Cultural Sexism and the Effectiveness of Gender (Non)Traditional Advertising: A Comparison of Purchase Intentions in Poland, South Africa, and the United Kingdom.

Findings regarding the effectiveness of (non)traditionally gendered advertisements are mixed and largely emanate from the United States. We tested the stereotype content model and ambivalent sexism theory cross-nationally in an advertising context and predicted that paternalistic (vs. envious) female stereotypes will trigger higher purchase intent (PI) irrespective of country (Hypothesis 1), viewers’ benevolent sexism will positively predict PI for paternalistic housewife advertisements (Hypothesis 2a), viewers’ hostile sexism will negatively predict PI for envious businesswoman advertisements (Hypothesis 2b), and these relationships with sexism will be confined to less gender egalitarian countries (i.e., Poland and South Africa) (Hypothesis 3). Statistical analyses of data from 468 Polish, South African, and British university students supported Hypothesis 1 and partially supported Hypotheses 2 and 3. The predicted patterns held for South Africa, but in Poland, viewers’ benevolence positively predicted PI for both advertisement types, with the exception of highly hostile women. British viewers’ hostility positively predicted PI for the housewife advertisement. Our findings support the cross-cultural applicability of the stereotype content model to advertising and suggest that the predictive role of sexism changes depending on its type, advertisement type, country, and gender. We recommend that advertisers should adopt a nuanced approach in predicting the effectiveness of gendered advertisements

Effects of antiplatelet therapy after stroke due to intracerebral haemorrhage (RESTART): a randomised, open-label trial

Background: Antiplatelet therapy reduces the risk of major vascular events for people with occlusive vascular disease, although it might increase the risk of intracranial haemorrhage. Patients surviving the commonest subtype of intracranial haemorrhage, intracerebral haemorrhage, are at risk of both haemorrhagic and occlusive vascular events, but whether antiplatelet therapy can be used safely is unclear. We aimed to estimate the relative and absolute effects of antiplatelet therapy on recurrent intracerebral haemorrhage and whether this risk might exceed any reduction of occlusive vascular events. Methods: The REstart or STop Antithrombotics Randomised Trial (RESTART) was a prospective, randomised, open-label, blinded endpoint, parallel-group trial at 122 hospitals in the UK. We recruited adults (≥18 years) who were taking antithrombotic (antiplatelet or anticoagulant) therapy for the prevention of occlusive vascular disease when they developed intracerebral haemorrhage, discontinued antithrombotic therapy, and survived for 24 h. Computerised randomisation incorporating minimisation allocated participants (1:1) to start or avoid antiplatelet therapy. We followed participants for the primary outcome (recurrent symptomatic intracerebral haemorrhage) for up to 5 years. We analysed data from all randomised participants using Cox proportional hazards regression, adjusted for minimisation covariates. This trial is registered with ISRCTN (number ISRCTN71907627). Findings: Between May 22, 2013, and May 31, 2018, 537 participants were recruited a median of 76 days (IQR 29–146) after intracerebral haemorrhage onset: 268 were assigned to start and 269 (one withdrew) to avoid antiplatelet therapy. Participants were followed for a median of 2·0 years (IQR [1·0– 3·0]; completeness 99·3%). 12 (4%) of 268 participants allocated to antiplatelet therapy had recurrence of intracerebral haemorrhage compared with 23 (9%) of 268 participants allocated to avoid antiplatelet therapy (adjusted hazard ratio 0·51 [95% CI 0·25–1·03]; p=0·060). 18 (7%) participants allocated to antiplatelet therapy experienced major haemorrhagic events compared with 25 (9%) participants allocated to avoid antiplatelet therapy (0·71 [0·39–1·30]; p=0·27), and 39 [15%] participants allocated to antiplatelet therapy had major occlusive vascular events compared with 38 [14%] allocated to avoid antiplatelet therapy (1·02 [0·65–1·60]; p=0·92). Interpretation: These results exclude all but a very modest increase in the risk of recurrent intracerebral haemorrhage with antiplatelet therapy for patients on antithrombotic therapy for the prevention of occlusive vascular disease when they developed intracerebral haemorrhage. The risk of recurrent intracerebral haemorrhage is probably too small to exceed the established benefits of antiplatelet therapy for secondary prevention
