Abstract
Purpose
The purpose of this article is to explore the capabilities and limitations of weblog search engines.
Design/methodology/approach
The features of a range of current blog search engines are described. These are then discussed and illustrated with examples that illustrate the reliability and coverage limitations of blog searching.
Findings
Although blog searching is a useful new technique, the results are sensitive to the choice of search engine, the parameters used and the date of the search. The quantity of spam also varies by search engine and search type.
Research limitations/implications
The results illustrate blog search evaluation methods and do not use a full‐scale scientific experiment.
Originality/value
Blog searching is a new technique, and one that is significantly different from web searching. Hence information professionals need to understand its strengths and weaknesses.

The purpose of this paper is to explore the growth and development of periodical literature on Web 2.0 technologies and their other fields.
Abstract
Purpose
The purpose of this paper is to explore the growth and development of periodical literature on Web 2.0 technologies and their other fields.
Design/methodology/approach
Bibliographic data of the articles published in the 13 leading peer‐reviewed journals are obtained from the Emerald database (www.emeraldinsight.com) directly using such keywords as “Web 2.0”, “blogs”, “wikis”, “RSS”, “social networking sites”, “podcasts”, “Mashup”, and multimedia sharing tools, i.e. YouTube and Flickr. The bibliographical surrogates such as author, title, subtitle, source, issue, volume, pages, etc. were recorded in MS‐Excel (2010) sheet for the analysis and interpretation of data. A bibliography of selected articles is provided.
Findings
The study found 206 research articles on the subject published in 13 leading library and information science journals of Emerald for period 2007‐2011. Further, the study found that 2009 was the most productive year with 69 articles. The study observed Online Information Review published 49 articles, and hence can be considered the core journal on the topic. Mike Thelwall from the UK was found to be the most prolific author, having authored or co‐authored five articles.
Research limitations/implications
The study was based on 206 research articles published during the years 2007‐2011. The study was restricted to this period because the Web 2.0 concept was originated during 2004‐2005 and the undertaken period has sufficient published literature on the topic.
Originality/value
The paper provides reliable and authentic information on the subject. This is the first study on this topic.

This study aims to offer a bibliometric analysis of the already substantial and growing literature on global virtual teams (GVTs).
Abstract
Purpose
This study aims to offer a bibliometric analysis of the already substantial and growing literature on global virtual teams (GVTs).
Design/methodology/approach
Using a systematic literature review approach, it identifies all articles in the Web of Science from 1999 to 2021 that include the term GVTs (in the title, the abstract or keywords) and finds 175 articles. The VOSviewer software was applied to analyze the bibliometric data.
Findings
The analysis revealed three dialogizing research clusters in the GVTs literature: a pioneering management information systems and organizational cluster, a general management cluster and a growing international management and behavioural studies cluster. Furthermore, it highlights the most cited articles, authors, journals and nations, and the network of strong and weak links regarding co-authorships and co-citations. Additionally, this study shows a change in research patterns regarding topics, journals and disciplinary approaches from 1999 to 2021. Finally, the analysis illustrates the position and centrality in the network of the most relevant actors.
Practical implications
The findings can guide management practitioners, educators and researchers to the most meaningful clusters of publications on GVTs, and help navigate and make sense of the vast body of the available literature. The importance of GVTs has been growing in the past two decades, and Covid-19 has accelerated the trend.
Originality/value
This study provides an updated and comprehensive systematic literature review on GVTs. To the best of the authors’ knowledge, it is also the first systematic literature review and bibliometry on GVTs. It concludes by suggesting future research paths.

Abstract
Purpose
The purpose of this research is to demonstrate the effectiveness of pictorial warning labels that leverage the risk of obesity as a deterrent against alcohol abuse. It evaluates the impact of three different kinds of warning labels that can potentially discourage alcoholic drinking: (1) a claim, in text format, that cautions consumers about the product (i.e. a responsibility warning statement); (2) a textual warning label, text-format information on the content of the product or the consequences of excessive consumption (i.e. a synthetic nutritional table); (3) a pictorial warning label, an image depicting a food product with a caloric content equivalent to that of an alcoholic beverage.
Design/methodology/approach
In Study 1, a 2 × 2 × 2 factorial design is used to evaluate the intention to buy different alcoholic cocktails. The stimuli comprised two cocktails that are similar in alcoholic volume, but different in their caloric content. The images of the products were presented across eight warning label conditions and shown to 480 randomly selected Italian respondents who quantified their intention to buy the product. In Study 2, a different sample of 34 Italian respondents was solicited with the same stimuli considered in Study 1, and neuropsychological measurements through Electroencephalography (EEG) were registered. A post hoc least significance difference (LSD) test is used to analyse data.
Findings
The results show that only the presence of an image representing an alcoholic beverage's caloric content causes a significant reduction in consumers' purchase intentions. This effect is due to the increase in negative emotions caused by pictorial warning labels.
Originality/value
The findings provide interesting insights on pictorial warning labels, which can influence the intention to purchase alcoholic beverages. They confirmed that the use of images in the warning labels has a greater impact than text, and that the risk of obesity is an effective deterrent in encouraging consumers to make healthier choices.
