The San Francisco Declaration on Research Assessment (DORA) was penned 5 years ago to articulate best practices for how we communicate and judge our scientific contributions. In particular, it adamantly declared that Journal Impact Factor (JIF) should never be used as a surrogate measure of the quality of individual research contributions, or for hiring, promotion, or funding decisions. Since t...

While health impact assessment (HIA) has typically been applied to projects, plans or policies, it has significant potential with regard to strategic considerations of major health issues facing society such as climate change. Given the complexity of climate change, assessing health impacts presents new challenges that may require different approaches compared to traditional applications of HIA...

The behaviour of the (I-V) characteristics is investigated in n+-i-n+ highly compensated Si resistors at temperatures 4.2-45K. The conduction mechanisms are discussed in detail here. The prebreakdown and breakdown regions of I-V characteristics were simulated by a one-dimensional model including the evidence of impurity high compensation and freeze out effects as well as the shallow-dopants imp...

M. R. Talukder Y. Maron

In a recent paper [1], Talukder proposed a new empirical formula for electron-impact ionization cross sections of He-like ions that was claimed to excellently agree with the available experimental and theoretical data. Discussing this agreement, the author of reference [1] makes extensive comparison with our recommended formula of reference [2] (referred to as “BRY” in [1] although it would be ...

Purpose – This study shows that the journal impact factor is not able to reflect the full impact of scholarly journals and provides an overview of alternative and complementary methods in journal evaluation. Design/methodology/approach – Aslib Proceedings (AP) is exemplarily analyzed with a set of indicators from five dimensions of journal evaluation, i.e. journal output, content, perception an...

In this paper we study a partially ionized plasma that corresponds to an arc discharge at atmospheric pressure. We derive an inviscid hydrodynamic/diffusion limit, characterized by two temperatures, from a system of Boltzmann type transport equations modelling that plasma problem. The original property of this system is that impact ionization is a leading order collisional process. As a consequ...

The relationship between the implantation and development of information technology (IT) and improvements in business performance has been a matter of interest to professionals and researchers in Management since the 1980’s. Despite numerous studies that have attempted to determine the full impact of IT, no conclusive results have as yet emerged. This situation has been termed the productivity ...

Comparison of electronand photon-impact processes as a method for determination of photo-ionization cross sections is described, discussed and shown to have many attractive features. Keywords—Transition probability, cross section, photoionization, electron-ionization, multi-photon process.

By collision-energy/electron-energy-resolved 2D Penning ionization electron spectroscopy as well as by theoretical calculations of the collisional ionization dynamics, the outer shape of molecular orbitals for ionization to X(Σ) and A(Π) states of CO was sensitively probed, and the anisotropy of the interaction between He*(2S) and CO was determined. Ionization to the B(Σ) state of CO was assign...
