The Relationship

A method for determining adequate quantities and locations of on-chip capacitors to maintain supply voltages at all locations on a chip within pre-specified limits given the switching activity of on-chip circuits was presented in [3]. In this paper, we extend the method to include current flow from the package and PCB. The effects of on-chip capacitance and other system parasitics on the time it takes for additional supply current to flow into a chip are discussed. The relationship between switching current, capacitance, system parasitic inductances, and on-chip noise is presented. These concepts are then applied to the subject of power delivery network (PDN) resonance. A 1-dimensional model for simulating PDN resonance is presented. The model includes chip, package, and PCB components, along with explicit networks for each chip power supply and their interactions. The topology of the model and the contributions of each model component are described. A design methodology for avoiding PDN resonance, presently in use on all IBM ASIC modules, is presented.

Practical Implications

Purpose The purpose of this paper is to analyze the relationship between organizations and sustainability as a field of knowledge possible to be accessed by descriptive and thematic representations extracted from administration area published papers about the subject. Design/methodology/approach This paper consists in a bibliometric study. It was considered five bases of journals indexation: AOM, Emerald, Elsevier, Sage and Wiley. By judgmental sampling, 11 journals were selected, in which, at the end of data collection, 192 papers were eligible to be analyzed by content and thematic analysis techniques. Findings In quantitative data analysis, it was implied that the field of knowledge identity was colonized by the Euro-American axis. In qualitative analysis, it was found that the investigated field of knowledge was built by 15 thematic representations, understood by three forms of comprehensions, enabled by four different debates. Practical implications In a political and ideological perspective of sustainability, the socioenvironmental interests are silenced by a dominant power. Along these lines, the theme is managed, instrumentalized and commercialized by a dominant power. This paper aims to make these relations between organizations and sustainability public. The investigated field of knowledge houses a dominant discursive representation interest in respect to the investigated relations. Originality/value This paper innovates by considering conceptual frameworks of sustainable development and sustainability developed from contributions extracted from organizational theories, sociological reflections and political science orientations. The selection was necessary to ensure the theoretical viability of the discussion proposed by this paper.

Purpose The purpose of this paper is to examine the constituents of personal discretionary non-work activities and their influence on the work values ethic (WVE). Design/methodology/approach The constituents of personal discretionary non-work activities and their relationship to the WVE for 1,349 employees drawn from three manufacturing companies were surveyed. The data was used to test a measure of WVE, to develop a valid measure of personal discretionary non-work activities and to test a model of the relationship between personal discretionary non-work activities and a WVE. Findings Data obtained from the survey enabled the identification of a valid measure of personal discretionary non-work activities and the components that made up this measure. A measure of WVE was shown to be both valid and reliable, and a model of the relationship between personal discretionary non-work activities and WVE was tested. Research limitations/implications A positive relationship between personal discretionary non-work activities and WVE was identified. However, the study was not designed to investigate motivations and such relationships should be the subject of future research. Practical implications Personal discretionary non-work activities were shown to be of importance for a major proportion of the study’s respondents and to contribute to the employees’ work ethic. Originality/value The study has extended the non-work and work literature and has identified a formative non-work measure that was able to be tested in an overall model.

The Relationship

Purpose – In 1990, Salovey and Mayer presented a framework for emotional intelligence (EI). This marked the beginning of 20 years of academic research, development, and debate on the subject of EI. A significant amount of previous research has attempted to draw out the relationship between EI and leadership performance. EI has been a uniquely controversial area of the social sciences. EI is based on three simple yet fundamental premises. This manuscript reviews the definitions and models in the field of EI with special emphasis on the Mayer ability model and the connection between EI and leadership. The paper aims to discuss these issues. Design/methodology/approach – This paper takes the form of a literature review. Findings – EI appears to have a foothold in both our popular vernacular and our academic lexicon. However, it is not entirely clear what future form it will take. Originality/value – This manuscript explores the current relationship between EI and leadership, discusses the various instruments and scales used to measure the construct, and examines the controversy and criticism surrounding EI. Finally, it illuminates some areas for additional research.
