PurposeThe purpose of this paper is to model and study the effectiveness of an attack on the anonymity of Internet users by a group of collaborating eavesdroppers.Design/methodology/approachThe paper is based on an analysis of the Internet topology. The study is based on two methods for choosing nodes that contribute the most to the detection of as many communicating Internet users as possible.FindingsThe paper illustrates that it is possible to compromise the anonymity of many Internet users when eavesdropping on a relatively small number of nodes, even when the most central ones are protected from eavesdropping.Research limitations/implicationsIt is assumed that the Internet users under attack are not using any anonymity enhancing technologies, but nodes can be protected from eavesdropping. It proposes a measure of the success of an attack on Internet users' anonymity, for a given deployment of collaborating eavesdroppers in the Internet.Practical implicationsThe paper shows that several, and not necessarily the most prominent, collaborating nodes can compromise the anonymity of a considerable portion of Internet users. This study also emphasizes that when trying to completely compromise the anonymity of Internet users, an eavesdroppers' deployment strategy that considers eavesdroppers' collaboration can result in substantial resource saving compared to choosing a set of the most prominent nodes.Originality/valueThe paper proposes a new measure of anonymity level in the network, based on the linkability of the Internet users. This paper is the first to present results of a non‐trivial Group Betweenness optimization strategy in large complex networks.

Purpose This paper reviews the latest management developments across the globe and pinpoints practical implications from cutting-edge research and case studies. Design/methodology/approach This briefing is prepared by an independent writer who adds their own impartial comments and places the articles in context. Findings If you search images of the word “strategy” on the internet, three of the first seven images to appear on Google (other search engines are available) include chess pieces, while two of the top ten hits involve light bulbs. Aside from the obvious conclusions that any strategic discussion should either involve chess grand masters or well-lit rooms, it is clear that most people assume winning games with lots of moves are possible is the key to a successful strategy. But is this a valid analogy, even at a high level? Originality/value The briefing saves busy executives and researchers hours of reading time by selecting only the very best, most pertinent information and presenting it in a condensed and easy-to-digest format.

Purpose The purpose of this paper is to analyse the ways clients find out about a sport centre and the factors that lead them to enrol and influence their satisfaction with their membership. A secondary objective was to determine the reasons for continuing to attend a sport centre and how they influenced satisfaction towards achievement. Finally, the authors aimed to identify differences between reasons for enroling and reasons for continuing at a sport centre. Design/methodology/approach A specially developed 16-item questionnaire was sent to 125,000 clients and 21,043 responses were obtained. Findings Clients who found out about the centre through a recommendation or the internet were 25 per cent more likely to be satisfied with it than those who knew of the centre due to proximity. Similarly, clients who had a specific motive to continue using the centre, for example, to prepare for a sports competition were twice as likely to be satisfied with their membership as any other group (p<0.001). Research limitations/implications It identifies a set of research priorities for the journal and the field. Practical implications In conclusion, the option of staying fit is established as the most effective recruitment method for retaining clients at the sport centre. Originality/value This paper intends to do is to establish the bases of information and knowledge for the treatment of high motives, as well as for managers of sports centres to remodel their strategies of marketing to attracting customers.

Purpose – The purpose of this paper is to explore the legitimacy needs and legitimation strategies of Internet start-ups in the context of industry dynamism. Design/methodology/approach – The purpose of this paper is to explore the legitimacy needs and legitimation strategies of Internet start-ups in the context of industry dynamism. Findings – The authors found that Internet start-ups are in great need of acquiring market and relational legitimacy at their nascent stages. Conformance to the environment is widely adopted by them as a legitimacy-enhancing strategy. There is an inverted “U” relationship between the maturity of the industry and the proactivity of any legitimation strategy in the sector. In the face of high- and low-level industry maturity, start-ups tend to employ prudent strategies to build up legitimacy. While in medium-mature industries, ventures are more likely to adopt proactive and aggressive strategies. Research limitations/implications – Due to the very nature of case methodology, this study is based on a small number of observations and it is set in the context of the Internet industry. The generalizability of its findings needs to be reinforced by further concrete studies. Practical implications – This paper suggests that industry dynamism should be taken into account carefully when implementing a choice of legitimation strategies. Originality/value – This study makes an attempt to further our understanding of how industry dynamism influences firms’ choices of legitimation strategies.

Purpose – The purpose of this paper is investigating the value of service guarantee (SG) program in Service e-Commerce (SeC) which is one resolution to promote service transactions. SeC is emerging as a booming form of e-commerce where various services are contracted, managed, sold and even delivered via the Internet. However, the uncertainty of service quality and the heterogeneity of buyer preferences have been major challenges to sustainable development of SeC. Design/methodology/approach – This study uncovered the value of SG in SeC by empirically analyzing the data collected from zhubajie.com, a well-known service e-marketplace in China, to classify the service providers, to indentify the predictors for SG subscription and to study the effects of SG on service providers’ business performance and service quality. Findings – The authors found that the distribution of service provisions is diversified in terms of low-success, mid-success and high-success providers, while proactive or high ability-ranking providers consistently tend to subscribe to SG program. The study revealed that SG has diverse effects on business performance for low-success and mid-success providers. For high-success providers, it seems to not be an effective choice for transaction promotion. Finally, the results showed that SG marginally improved service quality. Practical implications – This research provides some practical implications for SeC markets to improve SG program. In addition, the results also help service providers to understand the value of SG in depth. Originality/value – This article extended the research of SG from the traditional offline market to the online market, as with SeC, in which transactions are conducted without face to face contact.

Purpose To provide insights into holiday well-being, the purpose of this paper is to examine two inevitable traveller activities related to destinations’ gastronomy: pre-trip food information sourcing and the daily meals consumed. Design/methodology/approach A survey was carried out among 243 Finnish travellers. The findings are based on univariate analysis (t-test, ANOVA and regression analysis). Findings Pre-trip behaviour to ensure holiday well-being is based on travellers’ interests in food, an emotional desire for a sense of safety and a functional desire for convenience, while they collect information from the internet and guidebooks about recommended food places and local food as well as food safety and price level. Travellers’ place the highest importance on dinner for their holiday well-being, especially foodies – those travellers with a keen interest in food. Breakfast is the second most important meal contributing to holiday well-being. Practical implications These findings inform destination marketing organisations about what food dimensions they should emphasise in destination gastronomy-related marketing communication for tour operators and hotel and local restaurants about the essence of dinner and breakfast for holiday well-being. Originality/value The study provides insights into the role of destinations’ gastronomy in holiday well-being, which deserves to be studied in the current era of experiences and food interest.

PurposeIt is crucial to find a better portfolio optimization strategy, considering the cryptocurrencies' asymmetric volatilities. Hence, this research aimed to present dynamic optimization on minimum variance (MVP), equal risk contribution (ERC) and most diversified portfolio (MDP).Design/methodology/approachThis study applied dynamic covariances from multivariate GARCH(1,1) with Student’s-t-distribution. This research also constructed static optimization from the conventional MVP, ERC and MDP as comparison. Moreover, the optimization involved transaction cost and out-of-sample analysis from the rolling windows method. The sample consisted of ten significant cryptocurrencies.FindingsDynamic optimization enhanced risk-adjusted return. Moreover, dynamic MDP and ERC could win the naïve strategy (1/N) under various estimation windows, and forecast lengths when the transaction cost ranging from 10 bps to 50 bps. The researcher also used another researcher's sample as a robustness test. Findings showed that dynamic optimization (MDP and ERC) outperformed the benchmark.Practical implicationsSophisticated investors may use the dynamic ERC and MDP to optimize cryptocurrencies portfolio.Originality/valueTo the best of the author’s knowledge, this is the first paper that studies the dynamic optimization on MVP, ERC and MDP using DCC and ADCC-GARCH with multivariate-t-distribution and rolling windows method.

Practical Implications

PurposeDigital business platforms (DBPs) such as Alibaba and Google Shopping are partnership networks that use the Internet to bring service providers (e.g. retail vendors) and customers together. One of the benefits of DBPs is network effects, in which customers can purchase from multiple providers, giving rise to a unique network. However, few studies have explored which service providers benefit from network effects and which do not.Design/methodology/approachUsing the theories of transaction costs and network analysis, the authors apply network models to DBPs to understand which service providers benefit from network effects.FindingsThe authors identify three segments of service providers: (1) those with high prominence (connection to providers with high network centrality), (2) those with high network constraint (adjacent to isolated providers) and (3) those with low prominence and constraint. The authors find that segments (1) and (3) benefit from reciprocated customer exchanges, and thus benefit from network effects, while high constraint segment (2) providers do not benefit from reciprocated exchanges. Moreover, the authors find that for segments (2) and (3) future sales have a negative association with unreciprocated customer exchanges, while segment (1) has no significant association between unreciprocated exchanges and future sales.Research limitations/implicationsThe authors discuss implications for a multisided platform (MSP), as it decides which service providers to attract, promote and recommend. They can use this study’s results to know which segments of providers will increase network effects to make the platform more valuable.Practical implicationsThis paper provides managers of service platforms with strategies for managing relations with their service providers.Social implicationsService platforms are an important and disruptive business model. The authors need to understand how network effects operate to create efficient platforms.Originality/valueThis paper extends the literature on MSPs by quantifying network effects and showing not all service providers benefit equally on an MSP from network effects. Critical insights into network effects on the MSP are provided, including different ways it can impact provider sales.
