Toward a Comprehensive Understanding of Corporate Reputation: Concept, Measurement and Implications

Abstract: Corporate reputation is more important than ever. The highly turbulent business environment, increased public expectations, and pressure from different stakeholder groups have all contributed to the increased importance of examining and managing a company’s reputation. Academic scholars have been studying corporate reputation for the past two decades, with special attention during the past decade. This is evidenced by the special journals on corporate reputation such as the Corporate Reputation Review, special issues in various journals on corporate reputation and many academic conferences on this important research topic. Today, with the abundance of research on corporate reputation it was important to look back and reflect on these studies. It is important to provide an overall framework for understanding corporate reputation and its underlying components and measures. Accordingly, this paper aims to review the literature on corporate reputation, by examining the concept, its measurement, perspectives and overall implications on organizations. This paper offers a synthesis of the concept of corporate reputation as well as some implications for managers who want to actively manage their reputations.

Protest leadership in the age of social media

Abstract: This article challenges the idea that social media protest mobilization and communication are primarily propelled by the self-motivated sharing of ideas, plans, images, and resources. It shows that leadership plays a vital role in steering popular contention on key social platforms. This argument is developed through a detailed case study on the interaction between the administrators and users of the Kullena Khaled Said Facebook page, the most popular online platform during the Egyptian revolution of early 2011. The analysis specifically focuses on the period from 1 January until 15 February 2011. It draws from 1629 admin posts and 1,465,696 user comments, extracted via a customized version of Netvizz. For each day during this period, the three most engaged with posts, as well as the 10 most engaged with comments, have been translated and coded, making it possible to systematically examine how the administrators tried to shape the communication on the page, and how users responded to these efforts...

3D Interconnected Binder-Free Electrospun MnO@C Nanofibers for Supercapacitor Devices.

Abstract: Rational design of binder-free materials with high cyclic stability and high conductivity is a great need for high performance supercapacitors. We demonstrate a facile one-step synthesis method of binder-free MnO@C nanofibers as electrodes for supercapacitor applications. The topology of the fabricated nanofibers was investigated using FESEM and HRTEM. The X-ray photoelectron spectroscopy (XPS) and the X-ray diffraction (XRD) analyses confirm the formation of the MnO structure. The electrospun MnO@C electrodes achieve high specific capacitance of 578 F/g at 1 A/g with an outstanding cycling performance. The electrodes also show 127% capacity increasing after 3000 cycles. An asymmetric supercapacitor composed of activated carbon as the negative electrode and MnO@C as the positive electrode shows an ultrahigh energy density of 35.5 Wh/kg with a power density of 1000 W/kg. The device shows a superior columbic efficiency, cycle life, and capacity retention.
