TrustZone-based Trusted Execution Environments (TEEs) have been utilized extensively for the implementation of security-oriented solutions for several smart intra and inter-connected devices. Although TEEs have been promoted as the starting point for establishing a device root of trust, a number of published attacks against the most broadly utilized TEE implementations request a second view on their security. The aim of this research is to provide an analytical and educational exploration of TrustZone-based TEE vulnerabilities with the goal of pinpointing design and implementation flaws. To this end, we provide a taxonomy of TrustZone attacks, analyze them, and more importantly derive a set of critical observations regarding their nature. We perform a critical appraisal of the vulnerabilities to shed light on their underlying causes and we deduce that their manifestation is the joint effect of several parameters that lead to this situation. The most important ones are the closed implementations, the lack of security mechanisms, the shared resource architecture, and the absence of tools to audit trusted applications. Finally, given the severity of the identified issues, we propose possible improvements that could be adopted by TEE implementers to remedy and improve the security posture of TrustZone and future research directions.

AbstractPeer reviewers serve a vital role in assessing the value of published scholarship and improving the quality of submitted manuscripts. To provide more appropriate and systematic support to peer reviewers, especially those new to the role, this study documents the feedback practices and experiences of two award-winning peer reviewers in the field of education. Adopting a conceptual framework of feedback literacy and an autoethnographic-ecological lens, findings shed light on how the two authors design opportunities for feedback uptake, navigate responsibilities, reflect on their feedback experiences, and understand journal standards. Informed by ecological systems theory, the reflective narratives reveal how they unravel the five layers of contextual influences on their feedback practices as peer reviewers (micro, meso, exo, macro, chrono). Implications related to peer reviewer support are discussed and future research directions are proposed.

Weak interfacial interactions remain a bottleneck for composite materials due to their weakened performance and restricted applications. The development of core–shell engineering shed light on the preparation of compact and intact composites with improved interfacial interactions. This review addresses how core–shell engineering has been applied to energetic materials, with emphasis upon how micro-energetic materials, the most widely used particles in the military field, can be generated in a rational way. The preparation methods of core–shell structured explosives (CSEs) developed in the past few decades are summarized herein. Case studies on polymer-, explosive- and novel materials-based CSEs are presented in terms of their compositions and physical properties (e.g., thermal stability, mechanical properties and sensitivity). The mechanisms behind the dramatic and divergent properties of CSEs are also clarified. A glimpse of the future in this area is given to show the potential for CSEs and some suggestions regarding the future research directions are proposed.

In the last decade, an enormous amount of attention has been paid to piezoelectric harvesters due to their flexibility in design and the increasing need for small-scale energy generation. As a result, various energy review papers have been presented by many researchers to cover different aspects of piezoelectric-based energy harvesting, including piezo-materials, modeling approaches, and design points for various applications. Most of these papers have tried to shed light on recent progress in related interdisciplinary fields, and to pave the road for future prospects in the development of these technologies. However, there are some missing parts, overlaps, and even some contradictions in these review papers. In the present review of these review articles, recommendations for future research directions suggested by the review papers have been systematically summed up under one umbrella. In the final section, topics for missing review papers, concluding remarks on outlooks and possible research topics, as well as potentially misleading strategies, have been presented. The review papers have been evaluated based on their merits and subcategories and the authors’ choice papers have been presented for each section based on clear classification criteria.

We reviewed 58 empirical articles from the last two decades on experiential marketing in the e-commerce context. This literature review seeks to shed light into the fields of experiential and digital marketing, addressing the gaps in experiential aspects that appear during an online shopping session found in the literature. Thus, the paper identifies the elements that create the optimal consumers’ experience together with advantages, challenges, and strategic advice associated with the overall digital experience, an aspect that develops a more sustainable relationship between customers and e-businesses. The findings reveal that the most reported advantage of the overall digital experience is that it provides enhanced satisfaction, an aspect that is crucial for both consumers and online businesses, while some noted that frequent challenges are providing high levels of interactivity and trust. We found several other advantages and challenges of online consumer experience that led to the outlining of the strategic advice for online businesses, all being discussed in detail. The paper addresses a theoretical framework of digital marketing that is relevant for both academics and practitioners, suggestions for future research directions, and key research implications being offered.

Social impact assessment (SIA) provides a methodology for defining, monitoring and employing measures to demonstrate the benefits and/or harms created for target communities through evidence of social outcomes and impacts. Although a recent increase in the number of applications is seen, SIA lacks consensus in its methodology, which increases ambiguity and complicates the generalization of any results obtained from individual studies. The objectives of this study are to investigate the methodology of SIA in order to define trends, state of the art, limitations, knowledge gaps, and to recommend future research directions. This study employs a systematic mapping to determine the methods available to perform SIA, and more importantly to identify a set of fundamental challenges faced by practitioners using SIA. Articles are searched through online databases, and are limited to the English language. A total of 81 articles published between 2009 and 2019 were selected, of which 49 included a case study application. A total of 12 fundamental challenges were identified, based upon the screened articles, which serve as a starting point for future research directions to further enhance the SIA methodology.

AbstractThe aim was to explore the existing literature on emotion and strategic leadership in a systematic review and to synthesize it into a theoretical model. A literature review on emotion in connection to strategic leadership was undertaken. After adhering to the search strategy and exclusion criteria, 46 peer-reviewed texts consisting of articles and relevant book chapters remained. The texts were analyzed according to the grounded theory method (GTM) to generate a new theoretical model and a core variable was identified, organizational emotion shaping. The model attempts to show how the interaction of individual and organizational framing factors with the strategic leader's tasks and challenges lead to emotion shaping internal and external of the organization. Suggestions for future research were formed and suggestions of practical implications were given. This literature review and theoretical integration offers a starting point for potential areas of further exploration.

Customer analysis is receiving special attention from both researchers and professionals. The objective of this paper is to identify the trends of techniques used to address customer’s current problems and shed light on future research directions using a literature review. We reviewed the literature for the last five years. The findings revealed that customer purchase was the most popular technique used by the research community followed by customer satisfaction and visit wit. Whereas customer segmentation and customer churn were the least. However, the regression method was commonly used for predicting customer purchase and behavior. But, social media and big data are still in their early stages for customer analytics research.
