The use of chalcogenide elements, such as sulfur (S) and selenium (Se), as cathode materials in rechargeable lithium (Li) and sodium (Na) batteries has been extensively investigated. Similar to Li and Na systems, rechargeable potassium–sulfur (K–S) and potassium–selenium (K–Se) batteries have recently attracted substantial interest because of the abundance of K and low associated costs. However, K–S and K–Se battery technologies are in their infancy because K possesses overactive chemical properties compared to Li and Na and the electrochemical mechanisms of such batteries are not fully understood. This paper summarizes current research trends and challenges with regard to K–S and K–Se batteries and reviews the associated fundamental science, key technological developments, and scientific challenges to evaluate the potential use of these batteries and finally determine effective pathways for their practical development.

This paper presents the discussion with purpose to identify the orientation of teacher induction program in vocational education that is in line with changing times and future challenges. The problems associated with the teacher induction program in vocational education are whether the program has been oriented towards changes and future challenges. This research was conducted explanatory sequential mixed method approach. This study applies a six-step on research procedure. Respondents consisted of 52 novice teachers, 115 mentors, 15 principals, and 24 school supervisors. The subject of the qualitative research was nine resources persons. The respondents were given a Likert scale questionnaire to gather opinions and to be interviewed about the implementation of induction programs in vocational schools. Data were analyzed using PASW-18 and Atlas.ti software. The results of the study indicate that the future orientation of the induction program for novice vocational teachers involves many aspects in teacher professional development. These aspects include understanding of new target groups, developing job markets, technological developments, business/industry cooperation, regional development, new learning paradigms, and vocational education policy.

The political history of cyberspace can reveal much about contemporary and future cyber security challenges. This chapter includes some technological history but, more importantly, it also addresses the political forces and trends that fundamentally shaped the development of cyberspace. In doing so, it provides insight into why cyber security is much more than a technical challenge, and why politics can be simultaneously an obstruction to better global cyber security and also the best hope for it. Observing how political perceptions of cyber security threats have both changed and remained constant over time helps put current approaches into perspective, avoiding the two reductionist arguments that either ‘everything is different now’ or ‘it is the same as it ever was’. Addressing future challenges like the Internet of Things and future remedies like emergent cyber norms require a sound understanding of the past. Essentially, this chapter calls for much more careful and comprehensive engagement with the interrelationship between technological developments and political forces.

The Impact

The term environmental scanning (ES) refers to the way in which managers study their relevant business environment. More precisely, we define ES as both looking for and looking at information available in the business environment. These activities embrace all domains of gathering facts from external sources like competitive intelligence (CI) and market research, but take a more holistic, integrative perspective by considering consumers, competitors, and the technological developments in same industry and different industries as well (Scholz & Wagner, 2006). Choo, Detlor, and Turnbull (2001) give an overview of ES and empirical findings supporting the importance of ES activities in business organizations. ES helps managers foresee favorable as well as unfavorable influences and initiate strategies that enable their organizations to adapt to their business environments. This article: • outlines three perspectives on the challenges for environmental scanning arising from information dissemination by multimedia, • discusses opportunities for ES on the World Wide Web (WWW), and • exemplarily describes two software solutions for ES in multimedia. The remainder of the article is organized as follows: the next section discusses challenges for ES arising from the increase of multimedia technologies in the business environment. Then, we discuss the impact of the WWW on ES. Subsequently, we present the state of the art in ES practice as well as the supporting software. The article concludes with a brief outline of future challenges in the field of ES.

Abstract The angiotensin-converting enzyme 2 (ACE2) has emerged as a critical regulator of the renin–angiotensin system (RAS), which plays important roles in cardiovascular homeostasis by regulating vascular tone, fluid and electrolyte balance. ACE2 functions as a carboxymonopeptidase hydrolyzing the cleavage of a single C-terminal residue from Angiotensin-II (Ang-II), the key peptide hormone of RAS, to form Angiotensin-(1-7) (Ang-(1-7)), which binds to the G-protein–coupled Mas receptor and activates signaling pathways that counteract the pathways activated by Ang-II. ACE2 is expressed in a variety of tissues and overwhelming evidence substantiates the beneficial effects of enhancing ACE2/Ang-(1-7)/Mas axis under many pathological conditions in these tissues in experimental models. This review will provide a succinct overview on current strategies to enhance ACE2 as therapeutic agent, and discuss limitations and future challenges. ACE2 also has other functions, such as acting as a co-factor for amino acid transport and being exploited by the severe acute respiratory syndrome coronaviruses (SARS-CoVs) as cellular entry receptor, the implications of these functions in development of ACE2-based therapeutics will also be discussed.

The Brain

In recent years, rapid technological developments in the field of neuroimaging have provided several new methods for revealing thoughts, actions and intentions based solely on the pattern of activity that is observed in the brain. In specialized centres, these methods are now being employed routinely to assess residual cognition, detect consciousness and even communicate with some behaviorally non-responsive patients who clinically appear to be comatose or in a vegetative state. In this article, we consider some of the ethical issues raised by these developments and the profound implications they have for clinical care, diagnosis, prognosis and medical-legal decision-making after severe brain injury.

Self Report Data

With reference to EJPA’s unique and broad scope, the current study analyzed the characteristics of the authors as well as the topics and research aims of the 69 empirical articles published in the years 2009–2010. Results revealed that more than one third of the articles were written by authors affiliated with more than one country. With reference to their research aims, an almost comparable number of articles (1) presented a new measure, (2) dealt with adaptations of measures, or (3) dealt with further research on existing measures. Analyses also revealed that most articles did not address any particular field of application. The second largest group was comprised of articles related to the clinical field, followed by the health-related field of application. The majority of all articles put their focus on investigating questionnaires or rating scales, and only a small number of articles investigated procedures classified as tests or properties of interviews. As to further characteristics of the method(s) used, a majority of EJPA contributions addressed self-report data. Results are discussed with reference to publication demands as well as the current and future challenges and demands of psychological assessment.
