Purpose Reporters are considered unique in terms of their information needs and seeking from other groups of masses. As they are running information business, the purpose of the study is to know about their skills of seeking, evaluating and engaging with information effectively and efficiently. Design/methodology/approach A cross-sectional survey was conducted with electronic media reporters from 20 news channels to assess their information literacy skills (IL) and personal information management practices (PIM). Findings The results indicated that the study’s participants considered themselves as information literate. They perceived themselves competent and confident in IL skills for the overall scale and on its all sub-dimensions as well. Interestingly, the study findings show that IL skills affect PIM practices positively. However, they were less competent in advanced searching techniques (i.e. use of Boolean logic, truncation etc.) and cloud-based storing tools and applications. Practical implications The study has inferences for information professionals, educators, media owners and other stakeholders. Policymakers in electronic media, particularly media libraries should offer training opportunities by organizing workshops, seminars etc. to enhance their advanced IL as well as PIM skills at workplace. Originality/value Very few studies investigated the IL phenomenon beyond its skills and assessment aspects. The present study uniquely identified impact of IL on PIM practices of working electronic media journalists.

In this paper, a unified behavioral model of laser feedback based self-mixing interferometry (SMI) is proposed which is able to accurately model the SMI sensor signals encountered under experimental variable optical feedback conditions. The model provides correct SMI signals whether feedback is varied in a continuous or discrete manner, while spanning all major feedback regimes (such as weak-, moderate-, and strong-feedback regime) used for sensing applications. As a result, the proposed model allows the simulation of SMI signals in the presence of speckle which is of upmost importance to develop future efficient algorithms to reconstruct target displacements. The optical speckle usually occurs when the target of comparable surface roughness to the laser wavelength is moving as it induces variation of the optical feedback factor. The proposed model is shown to be able to address such cases and in particular to be able to reproduce very similar SMI signals to those acquired in the presence of speckle. It is thus anticipated that the proposed model would facilitate the design and testing of novel SMI algorithms and systems dedicated to the processing of variable optical feedback based SMI signals for metric sensing applications.

A 32-bit chipless RFID tag operating in the 4.5–10.9 GHz band is presented in this paper. The tag has a unique multiple-arc-type shape consisting of closely packed 0.2 mm wide arcs of different radii and lengths. The specific tag geometry provides multiple resonances in frequency domain of an RCS plot. A frequency domain coding technique has also been proposed to encode the tag’s RCS signature into a 32-bit digital identification code. The tag has an overall dimension of 17.9 × 17.9 mm2, resulting in a high code density of 9.98 bits/cm2 and spectral efficiency of 5 bits/GHz. The proposed tag is built on a low loss substrate bearing a very small footprint, thereby making it extremely suitable for large-scale product identification purposes in future chipless RFID tag systems.
