Several authors have proposed information seeking as an appropriate perspective for studying software maintenance activities. However, there is little research in the literature describing holistic information-seeking models in this context. Additionally, in the one instance where an information-seeking model has been proposed, the empirical evidence presented in support of that model is extrem...

The complexity involved in the understanding of human collaboration leads to the design of novel approaches for its study. Particularly, in the context of information seeking little is known about collaboration, indeed only during the last years the study of collaborative information seeking (CIS) has become a subject of interest in the research community. Considering the lack of appropriate me...

This paper describes the current status of my doctoral research. In my work I am developing a novel approach to studying division of workload in collaborative tasks, with a particular focus on exploring division of labour in collaborative information seeking. My approach is based on the application of an economic game to the problem of workload division. Using this game as a theoretical and emp...

Professional search in an engineering context includes users on different stages from novice to expert. We discuss how searching as learning can help to understand searching in a larger information seeking, workspace, and learning environment, giving users the tools and understanding to become experts over time. We present some findings of user interaction with engineering domain retrieval syst...

The study investigated the process of information channel selection of Jewish studies scholars in Israel according to two theoretical frameworks, the ‘cost–benefit ratio’ that focused on the quality of the information provided by the channel and the ‘least effort principle’ that focused on the accessibility of the channel. The study sought to identify which of the two parameters, quality of inf...

a preliminary palaeomagnetic results from basalt outcrops in northeast lebanon is reported. the remanence carrier of the characteristic magnetisation is magnetite.  both variations of susceptibility and anisotropy directional data show that the measured directions of thermoremanent magnetisation (trm) are representative of the ambient field at the time of cooling of these basalts through their ...

A drawback of extremum seeking-based control is the introduction of a high frequency oscillation into a system’s dynamics, which prevents even stable systems from settling at their equilibrium points. In this paper, we develop extremum seeking-based controllers whose control efforts, unlike that of traditional extremum seeking-based schemes, vanish as the system approaches equilibrium. Because ...

The valley degree of freedom in two-dimensional (2D) crystals recently emerged as a novel information carrier in addition to spin and charge. The intrinsic valley lifetime in 2D transition metal dichalcogenides (TMD) is expected to be markedly long due to the unique spin-valley locking behavior, where the intervalley scattering of the electron simultaneously requires a large momentum transfer t...

INTRODUCTION This study examines the general public's knowledge of mental health and explores effective tools to promote good mental health through a household survey of a representative sample of the Malaysian population residing in Klang Valley, Malaysia. METHODS A total of 587 respondents, aged 18 years and older, responded to a series of questions in relation to mental health issues. Resp...

We show that inversion symmetry breaking together with spin-orbit coupling leads to coupled spin and valley physics in monolayers of MoS2 and other group-VI dichalcogenides, making possible controls of spin and valley in these 2D materials. The spin-valley coupling at the valence-band edges suppresses spin and valley relaxation, as flip of each index alone is forbidden by the valley-contrasting...
