Homeland security literature in relation to terrorism publications: The source and the response

Summary The literature on Terrorism and National Security (NS), and Homeland Security (HS) presents two sides of a coin: one side demonstrates the problematic nature of terrorism and asks for solutions; the other side tries to find a response and solutions to the problem. It was expected that the NS literature would emanate from the same source material as the HS publications. Analysis of the literature of terrorism, homeland security, and national security on Science Citation Index (SCI) has shown that the material on terrorism and NS stems from the same scientific sources; that is, the Social Sciences. In contrast, the HS scientific literature originates in the exact sciences, engineering, and life and environmental sources. The three kinds of literature have grown remarkably in recent years; however, cross-section search strategy between terrorism and HS studies yields small retrieval sets. This means that few articles both present the problem and propose possible solutions. Currently, HS is on one side of the scholarly arena, and NS and terrorism literature on the other side; they advance mostly in lines parallel to each other, but as the researcher moves from observing the core scientific literature toward the more general material, this state of affairs changes. Another analysis of a multimedia database, WorldCatalog (which indexes mostly books, but also videos and computer materials, both scientific and popular) demonstrates a different trend; the same publications deal with both terrorism and HS counter-terrorism, and suggested solutions.

Publication attributes of leadership: what do they mean?

The article evaluates 48 approaches to leadership for the first time for the period of 1965–2016 using bibliometric methods. Our analysis combines four parameters: the number of publications, citations, self-citations, and dispersion of literature (a new parameter). The question of what is the most influential approach to leadership is addressed. We argue that the interplay among the four attributes observed in this study shows that transformational leadership is the most influential and popular approach to leadership in leadership studies today. However, there is a question of whether the excessive self-citations in this approach to leadership play a role in its augmented visibility.     

The feasibility of endocardial propagation mapping using magnetic resonance guidance in a Swine model, and comparison with standard electroanatomic mapping

The introduction of electroanatomic mapping (EAM) has improved the understanding of the substrate of ventricular tachycardia. EAM systems are used to delineate scar regions responsible for the arrhythmia by creating voltage or activation time maps. Previous studies have identified the benefits of creating MR-guided voltage maps; however, in some cases voltage maps may not identify regions of slow propagation that can cause the reentrant tachycardia. In this study, we obtained local activation time maps and analyzed propagation properties by performing MR-guided mapping of the porcine left ventricle while pacing from the right ventricle. Anatomical and myocardial late gadolinium enhancement images were used for catheter navigation and identification of scar regions. Our MR-guided mapping procedure showed qualitative correspondence to conventional clinical EAM systems in healthy pigs and demonstrated altered propagation in endocardial infarct models.     

Antisemitism and Islamophobia: what does a bibliometric study reveal?

Although Islamophobia and Antisemitism are two phenomena different in their nature, both represent a form of Otherness that entails a complicated inclusion into multi-ethnic societies of modern Europe and the United States. The purpose of the present study is to show how the research literature has portrayed both phenomena in terms of bibliometric data retrieved from the SCIE Clarivate Analytics database. In addition, we were interested to find out if there is a literature that connects Islamophobia and Antisemitism, its direction and influence. Our findings show that because publications and citations on Islamophobia are relatively new, the research in terms of publications draws the attention of academic society in the direction of research of Antisemitism, but the citations count of the literature on Islamophobia exceeds by far that of the literature on Antisemitism. Moreover, we found that although Antisemitism and Islamophobia are distinct trends, there is an interaction between the literatures that discuss both, and the research that combines the analysis of both phenomena gains more influence than research dedicated to each phenomenon separately.     

Structural and Functional Support by Left Atrial Appendage Transplant to the Left Ventricle after a Myocardial Infarction

The left atrial appendage (LAA) of the adult heart has been shown to contain cardiac and myeloid progenitor cells. The resident myeloid progenitor population expresses an array of pro-regenerative paracrine factors. Cardiac constructs have been shown to inhibit deleterious remodeling of the heart using physical support. Due to these aspects, LAA holds promise as a regenerative transplant. LAAs from adult mT/mG mice were transplanted to the recipient 129X1-SvJ mice simultaneously as myocardial infarction (MI) was performed. A decellularized LAA patch was implanted in the control group. Two weeks after MI, the LAA patch had integrated to the ventricular wall, and migrated cells were seen in the MI area. The cells had two main phenotypes: small F4/80+ cells and large troponin C+ cells. After follow-up at 8 weeks, the LAA patch remained viable, and the functional status of the heart improved. Cardiac echo demonstrated that, after 6 weeks, the mice in the LAA-patch-treated group showed an increasing and statistically significant improvement in cardiac performance when compared to the MI and MI + decellularized patch controls. Physical patch-support (LAA and decellularized LAA patch) had an equal effect on the inhibition of deleterious remodeling, but only the LAA patch inhibited the hypertrophic response. Our study demonstrates that the LAA transplantation has the potential for use as a treatment for myocardial infarction. This method can putatively combine cell therapy (regenerative effect) and physical support (inhibition of deleterious remodeling).     

Transient and continuant authors in a research field: The case of terrorism

The issue of research continuance in a scientific discipline was analyzed and applied to the field of terrorism. The growing amount of literature in this field is produced mostly by one-timers who “visit” the field, contribute one or two articles, and then move to another subject area. This research pattern does not contribute to the regularity and constancy of publication by which a scientific discipline is formed and theories and paradigms of the field are created. This study observed the research continuance and transience of scientific publications in terrorism by using obtainable “most prolific terrorism authors” lists at different points in time. These lists designed by several terrorism researchers, presented a few researchers who contributed to the field continuously and many others whose main research interest lay in another discipline. The four lists observed included authors who were continuants, transients, new-comers, and terminators (who left the field). The lack of continuous, full-time research in a research field is typical of many disciplines, but the influence of this research pattern on a field’s growth and stability is different for older, established disciplines than for new and formative fields of study. With in the former, intellectual mobility could contribute to the rise of new topics and probably enrich the particular scientific field; with the latter, by contrast, it could hamper the formation and growth of the field.
