Non-invasive brain stimulation in human stroke survivors

The use of electromagnetic currents toward understanding and curing human disease has long been of interest. In the 1980s, a dramatic increase in our understanding of brain function, along with parallel improvements in non-invasive brain stimulation (NIBS) technologies, subsequently caused rapid expansion of the field. Intraoperative monitoring techniques that incorporated single pulse stimulation were developed concurrently for the purpose of measuring corticospinal integrity (Merton & Morton, 1980a, 1980b); however, with the introduction of transcranial magnetic stimulation (TMS), the use of NIBS decisively exploded, opening a new window into the exploration and modulation of the brain (Barker and Jalinous, Lancet, 1(8437):1106–1107, 1985). Single pulse TMS, used initially to study inter-cortical physiology of the intact corticospinal tract, was thereafter investigated toward the rehabilitation of neurological and psychiatric conditions

Successful kinetic impact into an asteroid for planetary defense

While no known asteroid poses a threat to Earth for at least the next century, the catalog of near-Earth asteroids is incomplete for objects whose impacts would produce regional devastation1,2. Several approaches have been proposed to potentially prevent an asteroid impact with Earth by deflecting or disrupting an asteroid1-3. A test of kinetic impact technology was identified as the highest priority space mission related to asteroid mitigation1. NASA's Double Asteroid Redirection Test (DART) mission is the first full-scale test of kinetic impact technology. The mission's target asteroid was Dimorphos, the secondary member of the S-type binary near-Earth asteroid (65803) Didymos. This binary asteroid system was chosen to enable ground-based telescopes to quantify the asteroid deflection caused by DART's impact4. While past missions have utilized impactors to investigate the properties of small bodies5,6, those earlier missions were not intended to deflect their targets and did not achieve measurable deflections. Here we report the DART spacecraft's autonomous kinetic impact into Dimorphos and reconstruct the impact event, including the timeline leading to impact, the location and nature of the DART impact site, and the size and shape of Dimorphos. The successful impact of the DART spacecraft with Dimorphos and the resulting change in Dimorphos's orbit7 demonstrates that kinetic impactor technology is a viable technique to potentially defend Earth if necessary

Organizational architecture, ethical culture, and perceived unethical behavior towards customers:Evidence from wholesale banking

In this study, we propose and test a model of the effects of organizational ethical culture and organizational architecture on the perceived unethical behavior of employees towards customers. This study also examines the relationship between organizational ethical culture and moral acceptability judgment, hypothesizing that moral acceptability judgment is an important stage in the ethical decision-making process. Based on a field study in one of the largest financial institutions in Europe, we found that organizational ethical culture was significantly related to the perceived frequency of unethical behavior towards customers and to the moral acceptability judgment of this type of unethical behavior. No support was found for the claim that features of organizational architecture are associated with the perceived frequency of unethical behavior towards customers. This is the first study to document the differential effects of organizational architecture and organizational ethical culture on perceived unethical behavior of employees towards customers, in wholesale banking. Implications for managers and future research are discussed
