Social Identity Development and the Situation of Scientists and Engineers as New Leaders

The current study examined the retrospective experience of scientists and engineers as they became new unit leaders in science and engineering firms. The goal of the study was to propose a theory that would lead to a better understanding of how scientists and engineers can be successful in their evolution into new leaders. The evolution was considered in the context of Robledo, Peterson, and Mumford's (2012) 3‐Vectors Model to appreciate the situation in which new leaders in scientific and engineering firms find themselves. The evolution was then considered in the perspective of Social Identity Theory to understand the relational development of the scientist or engineer as a new leader. The theory that emerged was that without a sound understanding of both the situation and adaptation of a new sociotechnical identity, achieving success in the leadership role is, at best, uncertain. Identity development and situational understanding are both necessary to facilitate and expedite the transition of scientists and engineers into the new leadership role. The transition from staff‐level scientist to leader can be made more productive through individual and organizational action espoused herein. The implications reveal many aspects of importance for organizations, individuals, researchers, and educators in Science, Technology, Engineering, and Math (STEM) and similar technical disciplines.     

The Visual Representation of Border Tourism: Demilitarized Zone (DMZ) and Dokdo in South Korea

The demilitarized zone (DMZ) and Dokdo mark South Korea borders with North Korea and Japan respectively. Each borderland is a socially constructed symbolic cultural landscape shaped in part by tourism. In this study, a sample of 2202 online images was inspected using content‐semiotic analysis to understand how visual representation of border tourism works. It was found that visitors via social media and government censorship play major roles in constructing representations of (i) alienated borders with iconic war heritage attractions at the DMZ and (ii) an alienated and isolated Dokdo. Both borders highlight patriotic/nationalistic ‘flagging’ and the gaze across. Copyright © 2013 John Wiley & Sons, Ltd.     

Facebook posting activity and the selective amplification of earnings disclosures

This study examines the determinants of Facebook activity levels with a particular focus on Facebook activity around earnings announcements. Facebook activity is generally higher for firms with higher levels of analyst following, individual ownership, and trading volume, indicating that it is responsive to investor demand effects. Facebook activity also increases around earnings announcements, with the increase being largely attributable to posts containing earnings news. In general, therefore, firms use Facebook posts to amplify earnings news. Such activity is selective, however; it is lower for firms with high levels of information asymmetry, for firms reporting earnings that exactly meet the consensus analyst forecast amount, and when the earnings news is negative but the accompanying price movement is positive. Hence, firms appear to use Facebook to manage the level of attention paid to earnings news.     

Relative Effects of IFRS Adoption and IFRS Convergence on Financial Statement Comparability

One of the primary objectives of both adoption of IFRS and convergence between IFRS and U.S. GAAP is to increase financial statement comparability. Using a unique setting in Germany, we compare the effectiveness of these two approaches in achieving this desired outcome. Our empirical tests show that both adoption and convergence lead to an increase in comparability after the new enforcement regulation in 2005. However, difference‐in‐differences tests show that adoption does not lead to a significant incremental increase in comparability beyond convergence. The findings of this study should be of interest to regulators and standard setters as they assess alternative methods of aligning domestic standards with IFRS.     

Low amplitude P, QRS and T wave pattern in lead I--the "isoelectric lead I sign"

An applicant's electrocardiogram contains a low amplitude P, QRS and T wave pattern in lead I. The diagnostic and prognostic implications of this ECG pattern are discussed.     

Nonsustained wide QRS tachycardia during an exercise ECG stress test

The evaluation of a nonsustained wide QRS tachycardia in a life insurance applicant's exercise test presents a special challenge to the medical director because of the unpredictable and potentially lethal nature of these arrhythmias. Ventricular tachycardia accounts for up to 80% of wide QRS tachycardias in unselected populations and more than 95% of cases with a prior myocardial infarction. Malignant ventricular arrhythmias usually occur in the presence of significant structural heart disease. In this setting, ventricular arrhythmias carry a high risk of sudden cardiac death. Less commonly, ventricular tachycardia occurs in hearts that appear normal. In many such cases, however, the heart is in fact not normal, but rather has less visible abnormalities including derangements of cardiac ion channels or structural proteins. In these individuals, ventricular arrhythmias also carry a high risk of sudden cardiac death. There are, however, some ventricular tachycardia syndromes which occur in normal hearts that have a more benign prognosis.     

The challenge of inferior Q waves

The presence of unexpected Q waves in an applicant's electrocardiogram poses a diagnostic dilemma for the medical director. On the one hand, the Q waves may be the remnants of a previously unsuspected "silent" myocardial infarction. Conversely, unexpected Q waves may represent a normal or positional variant, or an important noncoronary type of heart disease. This case study illustrates some of the pitfalls in interpreting applicants' electrocardiograms containing Q waves in the inferior leads.     

Valuation and classification of company issued cash and share-puts

This paper examines whether investors’ valuations of cash and share-put warrants are influenced by their potential differential effect on firm solvency. It is motivated by the enactment of SFAS 150, which requires that all contingent put warrant obligations be classified as balance sheet liabilities regardless of put type. Consistent with the critics of SFAS150, we show that market participants differentially value cash and share-puts based on their solvency characteristics beyond the firm’s recorded assets and liabilities. Our results add to existing capital structure literature by suggesting that complex financial instruments (such as cash and share-puts) be reported separately from each other on a firm’s balance sheet.
