Abstract

Purpose

The purpose of this paper is to report a simple, room temperature approach to assemble dense, vertically aligned single‐walled carbon nanotubes (SWNTs) between a chip and its substrate acting as a kind of thermal interface material by virtue of better mechanical and thermal properties.

Design/methodology/approach

Two silicon chips, with shallow trenches about 2 μm deep on the surface, were pressed together face to face with the trench direction perpendicular to each other. SWNT aqueous solution was driven into the gap between the two chips by capillary force. Later, the sample was baked to remove the moisture completely.

Findings

SWNTs beams were found to be assembled in the gap and have their two ends bonding with the interface of the two chips, respectively. The shear strength of the two chips was measured, and the thermal conductivity of the stacked chip‐SWNTs‐chip was tested using a laser flash method. In result, shear strength up to about 100 kPa, and an average thermal conductivity of 19.3 W·m−1·K−1 were demonstrated.

Originality/value

The paper proposes an approach to grown dense SWNT array bridging a chip and its substrate, and these SWNTs have potential capability to provide mechanical strength and higher thermal conductance instead of commercial thermal interface materials.

Abstract

This paper examines the implications of the findings of evaluative tests regarding the retrieval performance of natural language in various subject fields. It suggests parallel investigations into the structure of natural language, with particular reference to terminology, as used in the different branches of basic science. The criteria for defining the terminological consistency of a subject are formulated and a measure suggested for determining the degree of terminological consistency.

Abstract

After a clarification of definitions important in methodological discussions, a brief history of early methodological thought in economics and political economy is presented. The development of “orthodox” methodology is traced, and the fundamental assumptions underlying neoclassical economic methodology are enumerated. Philosophical positions – both critical of and sympathetic to the orthodox assumptions – are presented. In addition, the advantages and disadvantages of various heterodox positions are surveyed. Throughout the paper, methodological justifications for the emphasis on primarily deductive, complex mathematical models in contemporary economics as practiced in the USA – especially in light of the relevance and importance of primarily verbal, interpretive methodologies in the realm of applied and policy‐oriented economics – are examined.

Abstract

Tonya and Anete are new players at sc’MOI, but this theme emerges at the tail end of sc’MOI so they are best to explicate it. This chapter describes the theoretical contributions of quantum storytelling theory (QST) and practice. Building on the application of complexity theory in the hard sciences as well as social contexts and theory on multimodal constituency, this chapter considers the areas of overlap and difference between quantum storytelling and its theoretical fellows, with special attention given to sociomateriality, storytelling, feminism, fractal, and complexity theory.

Abstract

Purpose

How a micro-founded discipline such as economics could deal with the increasing global economic reality? This question has been asked frequently since the last economic crisis that appeared in 2008. In this challenging context, some commentators have turned their attention to a new area of knowledge coming from physics: econophysics which mainly focuses on a macro-analysis of economic systems. By showing that concepts used by econophysicists are consistent with an existing economic knowledge (developed by J.S. Mill), the purpose of this paper is to claim that an interdisciplinary perspective is possible between these two communities.

Design/methodology/approach

The authors propose a historical and conceptual analysis of the key concept of emergence to emphasize the potential bridge between econophysics and economics.

Findings

Six methodological arguments will be developed in order to show the existence of conceptual bridges as a necessary condition for the elaboration of a common language between economists and econophysics which would not be superfluous, in this challenging context, to clarify the growing complexity of economic phenomena.

Originality/value

Although the economics and econophysics study same the complex economic phenomena, very few collaborations exist between them. This paper paves a conceptual/methodological path for more collaboration between the two fields.

Abstract

Purpose

This paper seeks to investigate the reading behaviour of scientists from an intradisciplinary perspective.

Design/methodology/approach

Different aspects of reading behaviour were studied including the amount of reading, the sources of reading, and the impact of factors such as age, academic status, academic activities and methods used for identifying articles on reading behaviour. The data were collected through a survey of 114 physicists and astronomers (faculty members and PhD students) at University College London. A total of 56 interviews were also conducted with PhD students and faculty members.

Findings

The results revealed intradisciplinary differences within physics and astronomy in terms of reading behaviour. The study showed that recently published articles account for a large proportion of the readings. Age and academic status have an influence on the age of papers read. The amount of reading is influenced by the type of activities academics conduct, meaning those who spend more time teaching read fewer papers and those who spend more time doing research read more papers.

Originality/value

The paper is the first to look at intradisciplinary differences within a single discipline and reveals the impact of some task‐related and information‐seeking factors on reading behaviour.

Abstract

The paper examined the need and the various attempts being made to go networking in Nigeria. It discusses the advantages derivable from shared resources between organisations institutions and various professional bodies. It cites the attempts of the Nigerian Intranet Group NUNets by the National Universities Commission and the co‐operation between the Obafemi Awolowo University Ile‐Ife and the International Centre for Theoretical Physics from Italy as worthwhile which should be encouraged. It however highlights some of the challenges facing these attempts in a developing country like Nigeria. Some of these are poor telecommunication systems, ineffective use of information technologies, inadequate financial backing and even lack of the technological know how. It finally advises that by the turn of the 21st century resource sharing electronically should be a common phenomenon in the developed countries.

Abstract

Purpose

The purpose of this paper is to present a narrative review of studies on the citing behavior of scientists, covering mainly research published in the last 15 years. Based on the results of these studies, the paper seeks to answer the question of the extent to which scientists are motivated to cite a publication not only to acknowledge intellectual and cognitive influences of scientific peers, but also for other, possibly non‐scientific, reasons.

Design/methodology/approach

The review covers research published from the early 1960s up to mid‐2005 (approximately 30 studies on citing behavior‐reporting results in about 40 publications).

Findings

The general tendency of the results of the empirical studies makes it clear that citing behavior is not motivated solely by the wish to acknowledge intellectual and cognitive influences of colleague scientists, since the individual studies reveal also other, in part non‐scientific, factors that play a part in the decision to cite. However, the results of the studies must also be deemed scarcely reliable: the studies vary widely in design, and their results can hardly be replicated. Many of the studies have methodological weaknesses. Furthermore, there is evidence that the different motivations of citers are “not so different or ‘randomly given’ to such an extent that the phenomenon of citation would lose its role as a reliable measure of impact”.

Originality/value

Given the increasing importance of evaluative bibliometrics in the world of scholarship, the question “What do citation counts measure?” is a particularly relevant and topical issue.

Abstract

Purpose

To introduce the Innovative Electronics Manufacturing Research Centre Flagship Project: Integrated Optical and Electronic Interconnect PCB Manufacturing, its objectives, its consortium of three universities and ten companies and to describe the university research being carried out. This paper briefly reviews the motivation for developing novel polymer formulations, fabrication techniques, layout design rules and characterisation techniques for hybrid electronic and optical printed circuit boards (PCBs) using multimode polymer optical waveguide interconnects.

Design/methodology/approach

The authors are investigating a number of different fabrication techniques which they compare with each other and with modelled calculations of waveguide components. The fabrication techniques include photolithography, laser ablation, direct laser writing, embossing, extrusion and ink jet printing.

Findings

A number of design rules for polymer multimode waveguides have been found and published. Techniques for ink jetting polymer to print waveguides and laser ablation techniques have been developed. New formulations of polymer which cure faster for direct writing have also been developed.

Research limitations/implications

Further work is needed to thicken the ink jet printed polymer and to investigate side wall roughness of the ablated waveguides and development of new polymer formulations for dry film. Further research is also needed on construction of prototype system demonstrators.

Practical implications

The fabrication techniques being developed are designed to be transferred to industrial PCB manufacturers to enable them to make higher value optical PCBs. The design rules being discovered are being entered into commercial PCB layout software to aid designers of optical PCBs.

Originality/value

The paper is of interest to PCB manufacturers who wish to upgrade their processes to be able to manufacture optical PCBs. The university research is original and some has been published as shown in the publications in the reference list.
