Abstract

Purpose

Health-related online fake news (HOFN) has become a major social problem. HOFN can lead to the spread of ineffective and even harmful remedies. The study aims to understand Internet users' responses to HOFN during the coronavirus (COVID-19) pandemic using the protective action decision model (PADM).

Design/methodology/approach

The authors collected pandemic severity data (regional number of confirmed cases) from government websites of the USA and China (Studies 1 and 2), search behavior from Google and Baidu search engines (Studies 1 and 2) and data regarding trust in two online fake news stories from two national surveys (Studies 2 and 3). All data were analyzed using a multi-level linear model.

Findings

The research detected negative time-lagged relationships between pandemic severity and regional HOFN search behavior by three actual fake news stories from the USA and China (Study 1). Importantly, trust in HOFN served as a mediator in the time-lagged relationship between pandemic severity and search behavior (Study 2). Additionally, the relationship between pandemic severity and trust in HOFN varied according to individuals' perceived control (Study 3).

Originality/value

The authors' results underscore the important role of PADM in understanding Internet users' trust in and search for HOFN. When people trust HOFN, they may seek more information to implement further protective actions. Importantly, it appears that trust in HOFN varies with environmental cues (regional pandemic severity) and with individuals' perceived control, providing insight into developing coping strategies during a pandemic.

Abstract

Purpose

This article outlines the development of the Refugee Job Search Process Framework (RJSPF), which was created to help identify barriers that refugees face when trying to find employment. The framework incorporates an interdisciplinary, multi-level approach to the job search, delving into research from migration studies and Industrial/Organizational psychology to outline factors that exist on both the side of the refugee applicant and the organization at each stage of the RJSPF. The authors also tested the RJSPF with Syrian refugees and service providers in Canada to examine the validity of each component of the model.

Design/methodology/approach

The authors used a semi-structured format to interview refugees and service providers on their experiences in either trying to find employment or helping their refugee clients with the job search process. After transcribing the interviews, the data were independently coded, quantified, and analysed using Nvivo software to validate the RJSPF.

Findings

The majority of the RJSPF either had high or moderate support from the interviews. The authors also identified 6 broader themes using thematic analysis, which include language fluency, credential recognition, Canadian experience “catch 22”, cultural incongruencies, employer exploitation, and mental health for successful employment.

Originality/value

The RJSPF is a new integration of disparate theories of job search experiences in a literature that lacks an organizing framework and perspective on the unique challenges refugees face in this area compared to other newcomers. In doing so, the authors use an interdisciplinary, multi-level approach that extends the nomological network of barriers facing refugees, therefore informing future research and practice.

Abstract

Purpose

The purpose of the study is to examine enterprise searching practices across different work areas and work tasks in an enterprise search system in an international biotechnology company.

Design/methodology/approach

A mixed-method approach studying employees' authentic search activities during a 4-month period by log data, questionnaire survey and interviews. The log data analysed the entire active searcher group, whereas the questionnaire and interviews focused on frequent searchers.

Findings

The three studies provided insight into the searching activities and an understanding of the way searchers used the enterprise search system to search for information as part of their work tasks. The data identified three searcher groups, each with specific search characteristics. Four work task types were identified, and for all four types the searchers applied a tracing searching technique with use of contextual and historical relationships as paths.

Practical implications

The findings point to the importance of knowledge on historical and contextual relations in enterprise search.

Originality/value

The work sheds new light on enterprise searchers' information search practices. A significant contribution is the identification of a tracing search method used in relation to four essential work task types. Another contribution is the importance of historical and contextual knowledge to support the tracing search and decide what paths to follow.

Abstract

Purpose

The study aims to paint a representative picture of the current state of search interfaces of Swedish online museum collections, focussing on search functionalities with particular reference to subject searching, as well as the use of controlled vocabularies, with the purpose of identifying which improvements of the search interfaces are needed to ensure high-quality information retrieval for the end user.

Design/methodology/approach

In the first step, a set of 21 search interface criteria was identified, based on related research and current standards in the domain of cultural heritage knowledge organization. Secondly, a complete set of Swedish museums that provide online access to their collections was identified, comprising nine cross-search services and 91 individual museums' websites. These 100 websites were each evaluated against the 21 criteria, between 1 July and 31 August 2020.

Findings

Although many standards and guidelines are in place to ensure quality-controlled subject indexing, which in turn support information retrieval of relevant resources (as individual or full search results), the study shows that they are not broadly implemented, resulting in information retrieval failures for the end user. The study also demonstrates a strong need for the implementation of controlled vocabularies in these museums.

Originality/value

This study is a rare piece of research which examines subject searching in online museums; the 21 search criteria and their use in the analysis of the complete set of online collections of a country represents a considerable and unique contribution to the fields of knowledge organization and information retrieval of cultural heritage. Its particular value lies in showing how the needs of end users, many of which are documented and reflected in international standards and guidelines, should be taken into account in designing search tools for these museums; especially so in subject searching, which is the most complex and yet the most common type of search. Much effort has been invested into digitizing cultural heritage collections, but access to them is hindered by poor search functionality. This study identifies which are the most important aspects to improve.

Abstract

Purpose

This study examines consumers' channel attitudes and choices leading to webrooming and showrooming, and how product attributes (informational vs experiential and perceived risk) moderate the effects of channel attitudes.

Design/methodology/approach

A research framework is built upon the heterogeneity of channel attitudes, the lack of intrachannel lock-in and interchannel synergy. A questionnaire-based survey yields 868 multi-channel consumer responses in China. Simultaneous equation modeling and STATA 12.0 are used to test the hypotheses.

Findings

Consumers webroom when buying high-risk informational products (e.g. personal computers or mobile phones). They webroom as well as showroom for high-risk experiential products (e.g. clothing or cosmetics). Moreover, a single channel is preferred to webrooming or showrooming for purchasing low-risk informational (e.g. books or stationery) and low-risk experiential (e.g. snacks or toys) products. The results also show that webrooming is more frequently used than showrooming by consumers.

Research limitations/implications

This study extends current understanding on multi-channel and omnichannel shopping behavior and highlights the role of product attributes in customer journey mapping.

Practical implications

This study offers retailers and other downstream firms a fresh perspective on multi-channel customer experience management and channel design.

Originality/value

This study offers a clear explanation on the commonalities and differences between webrooming and showrooming.

Abstract

Purpose

High-efficiency video coding (HEVC) is the latest video coding standard that has better coding efficiency than the H.264/advanced video coding (AVC) standard. The purpose of this paper is to design and develop an effective block search mechanism for the video compression-HEVC standard such that the developed compression standard is applied for the communication applications.

Design/methodology/approach

In the proposed method, an rate-distortion (RD) trade-off, named regressive RD trade-off is used based on the conditional autoregressive value at risk (CaViar) model. The motion estimation (ME) is based on the new block search mechanism, which is developed with the modification in the Ordered Tree-based Hex-Octagon (OrTHO)-search algorithm along with the chronological Salp swarm algorithm (SSA) based on deep recurrent neural network (deepRNN) for optimally deciding the shape of search, search length of the tree and dimension. The chronological SSA is developed by integrating the chronological concept in SSA, which is used for training the deep RNN for ME.

Findings

The competing methods used for the comparative analysis of the proposed OrTHO-search based RD + chronological-salp swarm algorithm (RD + C-SSA) based deep RNN are support vector machine (SVM), fast encoding framework, wavefront-based high parallel (WHP) and OrTHO-search based RD method. The proposed video compression method obtained a maximum peak signal-to-noise ratio (PSNR) of 42.9180 dB and a maximum structural similarity index measure (SSIM) of 0.9827.

Originality/value

In this research, an effective block search mechanism was developed with the modification in the OrTHO-search algorithm along with the chronological SSA based on deepRNN for the video compression-HEVC standard.

Abstract

Purpose

The motion vector estimation algorithm is very widely used in many image process applications, such as the image stabilization and object tracking algorithms. The conventional searching algorithm, based on the block matching manipulation, is used to estimate the motion vectors in conventional image processing algorithms. During the block matching manipulation, the violent motion will result in greater amount of computation. However, too large amount of calculation will reduce the effectiveness of the motion vector estimation algorithm. This paper aims to present a novel searching method to estimate the motion vectors effectively.

Design/methodology/approach

This paper presents a novel searching method to estimate the motion vectors for high-resolution image sequences. The searching strategy of this algorithm includes three steps: the larger area searching, the adaptive directional searching and the small area searching.

Findings

The achievement of this paper is to develop a motion vector searching strategy to improve the computation efficiency. Compared with the conventional motion vector searching algorithms, the novel motion vector searching algorithm can reduce the motion matching manipulation effectively by 50 per cent.

Originality/value

This paper presents a novel searching strategy to estimate the motion vectors effectively. From the experimental results, the novel motion vector searching algorithm can reduce the motion matching manipulation effectively, compared with the conventional motion vector searching algorithms.

Abstract

Online databases have become increasingly accessible to end users through the use of microcomputers. The quickly expanding family of end‐user databases and software support services reflects the diverse needs of end users. Two popular databases, Compu‐Serve and The Source, appeal to home and business users with direct access to such data as financial information, airline schedules, restaurant guides, weather news, and consumer tips. A related approach has been taken by DIALOG'S Knowledge Index and BRS/After Dark. Directed toward the home information consumer, these vendor services provide access to some 12 to 23 of their most frequently consulted online databases. Using simplified DIALOG and BRS search protocol, the microcomputer operator is charged a reduced fee by searching during evening and weekend hours. A third variation on end‐user searching exists in front‐end software programs such as OL'SAM, CAST and Userkit. These products allow the user to gain access to a variety of database vendors using a single search protocol; the user learns one set of commands which, through the mediation of the software, will work on several database systems. ISI's Sci‐Mate provides similar features.

Abstract

At the beginning of the 1970s it became apparent to the Ministry of Agriculture, Fisheries and Food that the use of computers for information work merited serious consideration. We had taken part in investigations which indicated that the technology was well developed and reliable. We knew that large scale commercial services were available. What we did not know was the real value of these external services to the Ministry. All the databases concerned were derived from very familiar printed secondary journals. Did mechanized operation offer substantial advantages? Was the cost justified? How could mechanized operations fit into the present library activities? If the use of computers did offer improved facilities, what administrative arrangements were necessary? It was decided, therefore, to attempt to answer these questions by the evaluation of external computer‐based bibliographic information services under practical conditions.
