The structure of K- and Cs-monolayers on Cu(0 0 1): diffraction experiments far from the Bragg point

The intensity analysis along the crystal truncation rods has been used to analyse in situ the adsorption behaviour and the structure of K and Cs on Cu(0 0 1) at submonolayer coverages and room temperature. Up to about 0.25 ML K atoms adsorb in hollow sites followed by formation of a quasihexagonal superstructure. In contrast, for Cs adsorption the data can be interpreted by the formation of quasihexagonal Cs islands that grow with increasing coverage. For K an effective radius of 1.6(1) Å independent of coverage is determined. For Cs we fnd d = 2.1 (1) Å after formation of the quasihexagonal superstructure

Half a Century of Work–Nonwork Interface Research: A Review and Taxonomy of Terminologies

The extensive interest in the work‐nonwork interface over the years has allowed scholars from multiple disciplines to contribute to this literature and to shed light on how professional and personal lives are related. In this paper, we have identified 48 terminologies that describe the interface or relationship between work and non‐work, and have organized them into mature, intermediate, and immature categories according to their stage of development and theoretical grounding. We also provide a taxonomy that places work‐nonwork interface terminologies into a matrix of six cells based on two dimensions: (1) type of nonwork being narrow or broad; and (2) nature of the mutual impact of work and nonwork domains on one another, characterizing the impact as negative, positive, or balanced. The type of nonwork dimension was informed by Frone's (2003) classification of employees’ lives into multiple subdomains; the mutual impact dimension was informed by frameworks that organized the literature in part by negative, positive, and balanced work‐nonwork interface constructs (e.g., Allen, 2012; Greenhaus & Allen, 2011). Theoretical contributions of the proposed taxonomy are discussed along with suggestions on important avenues for future research

Information Systems Analysis and Design: Past Revolutions, Present Challenges, and Future Research Directions

Systems Analysis and Design (SAND) is undoubtedly a pillar in the field of Information Systems (IS). Some researchers have even claimed that SAND is the field that defines the Information Systems discipline and is the core of information systems. The past decades have seen the development of Structured SAND methodologies and Object-Oriented Methodologies. In the early 1990s, key players in the field collaborated to develop the Unified Modeling Language and the Unified Process. Agile approaches followed, as did other dynamic methods. These approaches remain heavily employed in the development of contemporary information systems. At the same time, new approaches such as DevOps and DevSecOps continue to emerge. This paper curates these trends in SAND. It reviews past and present SAND research, discusses current challenges, and provides insights that can assist SAND researchers in identifying future SAND research streams and important future research directions
