Measuring Organizational Legitimacy in Social Media: Assessing Citizens’ Judgments With Sentiment Analysis

Abstract: Conventional quantitative methods for the measurement of organizational legitimacy consider mainly three sources that make judgments about organizations visible: news media, accreditation bodies, and surveys Over the last decade, however, social media have enabled ordinary citizens to bypass the gatekeeping function of these institutional evaluators and autonomously make individual judgments public This inclusion of voices beyond functional and formally organized stakeholder groups potentially pluralizes the ongoing discussions about organizations The individual judgments in blogs, tweets, and Facebook posts give indication about the broader fit between an organization’s perceived behavior and heterogeneous social norms and therefore constitute an indicator of organizational legitimacy that can be accessed and measured We propose the use of social media data and sentiment analysis to study the affect-based responses to organizational actions by citizens We critically discuss and compare the method wi

Dual black holes in merger remnants – II. Spin evolution and gravitational recoil

Abstract: Using high-resolution hydrodynamical simulations, we explore the spin evolution of massive dual black holes orbiting inside a circumnuclear disc, relic of a gas-rich galaxy merger. The black holes spiral inwards from initially eccentric co- or counter-rotating coplanar orbits relative to the disc’s rotation, and accrete gas that is carrying a net angular momentum. As the black hole mass grows, its spin changes in strength and direction due to its gravito-magnetic coupling with the small-scale accretion disc. We find that the black hole spins loose memory of their initial orientation, as accretion torques suffice to align the spins with the angular momentum of their orbit on a short time-scale (1–2 Myr). A residual off-set in the spin direction relative to the orbital angular momentum remains, at the level of 10 ◦ for the case of a cold disc, and 30 ◦ for a warmer disc. Alignment in a cooler disc is more effective due to the higher coherence of the accretion flow near each black hole that reflects the largescale coherence of the disc’s rotation. If the massive black holes coalesce preserving the spin directions set after formation of a Keplerian binary, the relic black hole resulting from their coalescence receives a relatively small gravitational recoil. The distribution of recoil velocities inferred from a simulated sample of massive black hole binaries has median 70 km s −1 ,

Reduced discontinuation of antihypertensive treatment by two-drug combination as first step. Evidence from daily life practice

Abstract: ObjectivesTo measure persistence with antihypertensive drug therapy in patients initiating treatment with mono or combination therapy.MethodsData analysis was based on two cohorts of patients, that is, a cohort derived from the registration of drug prescriptions in all residents of the Lombardy regi

Gluon PDF constraints from the ratio of forward heavy-quark production at the LHC at $$\sqrt{S}=7$$ and 13 TeV

Abstract: We discuss production of charm and bottom quarks at forward rapidity in pp collisions at the LHC, updating the QCD predictions for the run at [Formula: see text] TeV. We show that, while the absolute rates suffer from large theoretical systematics, dominated by scale uncertainties, the increase relative to the rates precisely measured at 7 TeV can be predicted with an accuracy of a few percent, sufficient to highlight the sensitivity to the gluon distribution function.

Visit-to-Visit Blood Pressure Variability, Carotid Atherosclerosis and Cardiovascular Events in the European Lacidipine Study on Atherosclerosis

Abstract: Background—In high-cardiovascular-risk treated hypertensive patients, the incidence of cardiovascular events has been reported to relate to visit-to-visit blood pressure (BP) variability. We invest...
