This paper presents a self‐consistent I‐V simulation technique for an RTD with defect wells placed inside the barriers. The motivation of this paper was to model the excess valley current by a defect‐assisted tunneling mechanism. We have calculated the transmission coefficients and I‐V characteristics self consistently with Poisson's equation coupled to quantum mechanical tunneling through the barrier. The shape of transmission coefficient was broadened and greatly enhanced in the off‐resonance region when the defect well was introduced in the barriers. Our results gave a good qualitative estimation of the valley current and the peak to valley current ratio (PVCR).

This is a troubled age for democracy, but the nature of that trouble and why it is a problem for democracy is an open question, not easy to answer. Widespread wishing for responsible leaders who respect democratic norms and pursue policies to benefit people and protect the vulnerable don’t help much. The issue goes well beyond library contexts, but it is important that those in libraries think through our role in democracy as well. Micro-targeting library-centric problems won’t be effective and don’t address the key issue of this volume. The author can only address the future if we recover an understanding of the present by building up an understanding of actually-existing democracy: (1) the scope must be narrowed to accomplish the task; (2) the characteristics of the retreat from democracy should be established; (3) core working assumptions and values – what libraries are about in this context – must be established; (4) actually-existing democracy should then be characterized; (5) the role of libraries in actually-existing democracy is then explored; (6) the source and character of the threat that is driving the retreat from democracy and cutting away at the core of library assumptions and values is analyzed; (7) the chapter concludes by forming a basis of supporting libraries by unpacking their contribution to building and rebuilding democratic culture: libraries are simultaneously less and more important than is understood.

Interest in psychological resilience has grown rapidly in the last couple of decades (Britt, Sinclair, & McFadden, 2016; King & Rothstein, 2010; Youssef & Luthans, 2007). Psychological resilience occurs when a person can “recover, re-bound, bounce-back, adjust or even thrive” in the face of adversity (Garcia-Dia, DiNapoli, Garcia-Ona, Jakubowski, & O’flaherty, 2013, p. 264). As such, resilience can be conceptualized as a state-like and malleable construct that can be enhanced in response to stressful events (Kossek & Perrigino, 2016). It incorporates a dynamic process by which individuals use protective factors (internal and external) to positively adapt to stress over time (Luthar, Cicchetti, & Becker, 2000; Rutter, 1987). Building on the dual-pathway model of resilience, we integrate adaptive and proactive coping to the resilience development process and add a heretofore unexamined perspective to the ways in which resilience changes over time. We propose that resilience development trajectories differ depending on the type of adversity or stress experienced in combination with the use of adaptive and proactive coping. We outline the need for future longitudinal studies to examine these relationships and the implications for developing resilience interventions in the workplace.

In this chapter the relationship between job design and older workers is considered. Starting from a conceptual definition of what the concept job and work design is, we consider theoretic approaches to the study of job design over the last decades, including recent frameworks, measurement, and research. We follow this with a specific focus on the topic of job design for older workers. We argue that the rules of “good job design” are not applicable to all workers, focusing specifically on the issues of age and career stage. We next show through a theoretical model and some empirical research that some job characteristics may be more suitable or beneficial for people in older age groups or later stages of their careers (e.g., Truxillo, Cadiz, Rineer, Zaniboni, & Fraccaroli, 2012). Empirical support for the role of age in job design is considered. We conclude by defining some avenues for future research, including the identification of additional factors that may determine how age and job characteristics affect worker behavior, attitudes, and well-being.

This chapter explores “politic talks” (also known as political information) on the websites of academic libraries in land-grant state universities of the South in the context of a global retreat of democracy that emerged during former President Trump’s regime as the 45th President of the United States. The exploratory qualitative evaluation applies website content analysis of seven information offerings in three categories that include: (1) information sources (collections, resources), information policy and planning (assigned role, strategic representation), and connections (internal, external, news and events). Promising practices and illustrative examples of “politic talks” representation on academic library websites show how they are serving as significant providers of political information during current politically turbulent times. The discussion of these findings in relation to each state’s voting likelihood based on trends since 2000 has significant political implications in enhancing the role of academic libraries moving forward.
