High in the Hierarchy: How Vertical Location and Judgments of Leaders' Power are Interrelated

Leadership implies power. We argue, from a social embodiment perspective, that thinking about power involves mental simulations of vertical location. Three studies tested whether judgments of leaders’ power and information on a vertical location are interrelated. In Studies 1a-c, participants judged a leader's power after being presented with, among other information, an organization chart containing either a long or a short vertical line. A longer vertical line increased judged power. Study 2 showed that this effect persists when longer (vs. shorter) vertical lines are presented in an independent priming task and not in an organization chart, and that horizontal lines do not have the same effect. Finally, Studies 3a and 3b showed the reverse causal effect: Information about a leader’s power influenced participants’ vertical positioning of a leader’s box in an organization chart and of a leader picture into a team picture. Implications for leadership communication are discussed

Power and vertical positions in an organization chart

Study 1a of Giessner and Schubert (2007) found a causal effect of vertical spatial cues on power judgments. Recent work showed that this was a false positive (Klein et al., 2018). Here, we test whether another paradigm (i.e., original Study 3a) can be replicated, and develop an adjusted paradigm of original Study 1a to clarify what kind of vertical spatial cues influence power judgments. Our current preregistered Study 1 confirms original Study 3a of Giessner and Schubert (2007). It shows that information about the power of a leader is represented spatially by placing the leader’s box higher in an organigram. Our current Study 2 distinguishes vertical ranks from magnitude of vertical spatial difference without changes in rank. The original Study 1a and the failed replication manipulated only magnitude while leaving rank equal. We confirm the null finding here. However, we also find that vertical rank order does indeed affect power judgments, again in a preregistered study, and in line with prior work. In sum, building on earlier work and the failed replication, we clarify that vertical rank order, but not magnitude of elevation, are associated with power judgments

Astroparticle Physics with a Customized Low-Background Broad Energy Germanium Detector

The MAJORANA Collaboration is building the MAJORANA DEMONSTRATOR, a 60 kg array of high purity germanium detectors housed in an ultra-low background shield at the Sanford Underground Laboratory in Lead, SD. The MAJORANA DEMONSTRATOR will search for neutrinoless double-beta decay of 76Ge while demonstrating the feasibility of a tonne-scale experiment. It may also carry out a dark matter search in the 1-10 GeV/c^2 mass range. We have found that customized Broad Energy Germanium (BEGe) detectors produced by Canberra have several desirable features for a neutrinoless double-beta decay experiment, including low electronic noise, excellent pulse shape analysis capabilities, and simple fabrication. We have deployed a customized BEGe, the MAJORANA Low-Background BEGe at Kimballton (MALBEK), in a low-background cryostat and shield at the Kimballton Underground Research Facility in Virginia. This paper will focus on the detector characteristics and measurements that can be performed with such a radiation detector in a low-background environment.Comment: Submitted to NIMA Proceedings, SORMA XII. 9 pages, 4 figure

Risk profiles and one-year outcomes of patients with newly diagnosed atrial fibrillation in India: Insights from the GARFIELD-AF Registry.

BACKGROUND: The Global Anticoagulant Registry in the FIELD-Atrial Fibrillation (GARFIELD-AF) is an ongoing prospective noninterventional registry, which is providing important information on the baseline characteristics, treatment patterns, and 1-year outcomes in patients with newly diagnosed non-valvular atrial fibrillation (NVAF). This report describes data from Indian patients recruited in this registry. METHODS AND RESULTS: A total of 52,014 patients with newly diagnosed AF were enrolled globally; of these, 1388 patients were recruited from 26 sites within India (2012-2016). In India, the mean age was 65.8 years at diagnosis of NVAF. Hypertension was the most prevalent risk factor for AF, present in 68.5% of patients from India and in 76.3% of patients globally (P < 0.001). Diabetes and coronary artery disease (CAD) were prevalent in 36.2% and 28.1% of patients as compared with global prevalence of 22.2% and 21.6%, respectively (P < 0.001 for both). Antiplatelet therapy was the most common antithrombotic treatment in India. With increasing stroke risk, however, patients were more likely to receive oral anticoagulant therapy [mainly vitamin K antagonist (VKA)], but average international normalized ratio (INR) was lower among Indian patients [median INR value 1.6 (interquartile range {IQR}: 1.3-2.3) versus 2.3 (IQR 1.8-2.8) (P < 0.001)]. Compared with other countries, patients from India had markedly higher rates of all-cause mortality [7.68 per 100 person-years (95% confidence interval 6.32-9.35) vs 4.34 (4.16-4.53), P < 0.0001], while rates of stroke/systemic embolism and major bleeding were lower after 1 year of follow-up. CONCLUSION: Compared to previously published registries from India, the GARFIELD-AF registry describes clinical profiles and outcomes in Indian patients with AF of a different etiology. The registry data show that compared to the rest of the world, Indian AF patients are younger in age and have more diabetes and CAD. Patients with a higher stroke risk are more likely to receive anticoagulation therapy with VKA but are underdosed compared with the global average in the GARFIELD-AF.

Does Distance from the Equator Predict Self-Control? Lessons from the Human Penguin Project

We comment on the proposition “that lower temperatures and especially greater seasonal variation in temperature calls for individuals and societies to adopt…a greater degree of self-control”, for which we cannot find empirical support in a large dataset with data-driven analyses. After providing more nuance in our theoretical review, we suggest revisiting their model with an eye to the social determinants of self-control
