Controversial information systems (IS) represent a unique context in which certain members of a user's social circle may endorse the use of a system while others object to it. The purpose of this paper is to explore the simultaneous and often conflicting roles of such positive and negative social influences through social learning and ambivalence theories in shaping user adoption intention of a representative case of controversial IS, namely online dating services (ODS).

The model was tested with two empirical studies using structural equation modeling techniques. The data of these studies were collected from 451 (Study 1) and 510 (Study 2) single individuals (i.e. not in a relationship).

(1) Positive social influence has a stronger impact on perceived benefits and adoption intention, while negative social influence exerts a greater impact on perceived risks; (2) positive and negative social influences affect adoption intention toward ODS differently, through benefit and risk assessments; and (3) ambivalence significantly negatively moderates the effects of social influences on adoption.

This study enriches and extends the IS use, ambivalence theory, prospect theory, and social learning theory research streams. Furthermore, this study suggests that it is necessary to focus on not only the oft-considered positive but also negative social influences in IS research.

Online dating services have been growing rapidly in recent years. However, adopting these services may involve high risk and trust issues among potential users toward both online dating services and the daters they introduce to users. The purpose of this paper is to investigate how perceived benefits vs risks, and trust vs distrust affect user adoption vs non-adoption intentions toward using this rather controversial information and communications technology in the context of online dating.

Structural equation modeling was used to evaluate the research model using data from a survey of 451 single individuals.

The results indicated that perceived benefits play more essential roles in adoption, while perceived risks affect non-adoption more. Individuals' trust in online dating service predicts a major portion of the variation in user benefit perceptions, while distrust in online dating service and in daters that users might select significantly influence perceived risks. Moreover, benefit and risk perceptions can mediate the impacts of trust and distrust on both adoption and non-adoption decisions.

This study extends theories of decision-making in the use of controversial information technologies such as in the case of online dating. It investigates the coexistence of various trust and distrust beliefs as well as benefit and risk perceptions, and their different impacts on adoption and non-adoption in online dating services.

On account of its easy and intuitive usage as well as obvious advantages (e.g. access to work data from anywhere, at any time and through any means) the evolutionary cloud computing paradigm favors the use of shadow IT. Since many employees are not aware of the associated risks and possible legal violations, unauthorized use of cloud computing services could result in substantial risk exposure for any company. The purpose of this paper is to explore and to extend the body of knowledge concerning the topic of cloud computing with regard to shadow IT.

The aim of this contribution is to identify the reasons for the use of cloud computing services and the resulting shadow IT from an employee’s perspective, to demonstrate the counteractions a company may take against the unauthorized use of cloud computing services and to elaborate on the inherent opportunities and risks. We follow a mixed-methods approach consisting of a systematic literature review, a cloud computing awareness study, a vignette study and expert interviews.

Based on a triangulation of the data sets, the paper at hand proposes a morphological box as well as a two-piece belief-action-outcome model, both from an employee’s and employer’s point of view. Our findings ultimately lead to recommendations for action for employers to counteract the risk exposure. Furthermore, also employees are sensitized by means of insights into the topic of unauthorized usage of cloud computing services in everyday working life.

The limitations of the triangulation reflect the limitations of each applied research method. These limitations justify why a mixed-methods approach is favored – rather than relying on a single source of data – because data from various sources can be triangulated.

The paper includes recommendations for action for the handling of the unauthorized usage of cloud computing services within a company, e.g., the set up of a company-wide cloud security strategy and the conduction of an anonymous employee survey to identify the status quo.

This paper fulfills an identified need to explore the usage of cloud computing services within the context of shadow IT.

Over the last few decades, corporate social responsibility (CSR) has received a large amount of attention in research and in practice. As a response to the growing awareness of and concern about social and environmental issues, an increasing number of companies are proactively publishing their CSR-related principles and activities. The overall research question of this study is derived from legitimacy theory and is aimed at elucidating the relationship between industry sector and CSR communication. The paper aims to discuss these issues.

The empirical examination encompasses a sample that includes the annual reports of all German DAX-30 companies from 1998 to 2009. First, based on a content analysis, categories of CSR-related communication are defined. Second, these categories are used in a quantitative analysis with a longitudinal perspective to evaluate the hypothesis that companies in controversial industries communicate their CSR more intensely than companies in non-controversial industries.

The qualitative study leads to a category system that accounts not only for CSR-related activities but also for CSR philosophies and motives as the normative basis of CSR communication. The quantitative results support the hypothesis that companies in controversial industries are more active in CSR communication than companies in non-controversial industries.

Existing studies analysing CSR communication activity have been largely inconsistent and often use unsystematic approaches in choosing industries for comparison. Therefore, in this study, to overcome some of these deficiencies, a combination of quantitative and qualitative approaches addresses the concept of controversial industries.

This paper aims to improve the recommendations performance for cold-start users and controversial items. Collaborative filtering (CF) generates recommendations on the basis of similarity between users. It uses the opinions of similar users to generate the recommendation for an active user. As a similarity model or a neighbor selection function is the key element for effectiveness of CF, many variations of CF are proposed. However, these methods are not very effective, especially for users who provide few ratings (i.e. cold-start users).

A new user similarity model is proposed that focuses on improving recommendations performance for cold-start users and controversial items. To show the validity of the authors’ similarity model, they conducted some experiments and showed the effectiveness of this model in calculating similarity values between users even when only few ratings are available. In addition, the authors applied their user similarity model to a recommender system and analyzed its results.

Experiments on two real-world data sets are implemented and compared with some other CF techniques. The results show that the authors’ approach outperforms previous CF techniques in coverage metric while preserves accuracy for cold-start users and controversial items.

In the proposed approach, the conditions in which CF is unable to generate accurate recommendations are addressed. These conditions affect CF performance adversely, especially in the cold-start users’ condition. The authors show that their similarity model overcomes CF weaknesses effectively and improve its performance even in the cold users’ condition.

The purpose of this study is to examine the concept of consumer power, in particular the power or bloggers in the online environment and how this might be applied to the regulation of advertising.

Utilising Denegri‐Knott's (2006) four on‐line power strategies, a content analysis of weblogs of Tourism Australia's “Where the bloody hell are you?” advertising campaign is undertaken. Blogger behaviour towards this controversial campaign is documented and consumer power strategies are examined.

This study reveals that bloggers are circumventing the traditional self regulatory process by distributing information, opinion, and even banned advertising material, thereby forming power hubs of like‐minded people, with the potential to become online pressure groups, augmenting the traditional powers of consumers in the self regulatory process.

Limitations include a single case context and its exploration of a single media tool (weblogs). Also, bloggers are not representative of the general public, but do provide an alternative to the general category of complainants.

The paper provides evidence that bloggers are defacto regulators in the online environment providing judgements on advertising campaigns, supporting those with like‐minded views and disciplining others, and even making banned advertisements publicly available. Advertisers should be mindful of this activity in developing campaigns, especially in formulating controversial campaigns aimed to be disseminated online.

The paper is the first to relate consumer power in the online environment to self‐regulation. It is also first to study a new group of advertising complainants – the bloggers.

EU social policy is perhaps the most controversial aspect of European integration yet, despite all the political clashes on the matter, concepts like “social Europe” or “social dimension” remain ill‐defined and imprecise terms. Intends to outline and clarify in detail the debate about whether or not the European Union should have competence with regard to labour market affairs. A key message is that social policy has been controversial because it has become embroiled in the debate about the future political direction of the EU. In particular, three contrasting political models –symbiotic integration, integrative federalism and neo‐liberalism – have been put forward as organizing principles for the EU and each has a coherent view of what form social policy should take at the European level. It is the clash between these three models that has caused EU social policy to be so contestable and intractable.

This paper aims to examine whether corporate social responsibility influences the cost of equity capital of firms operating in controversial industry sectors.

This paper computes the ex-ante cost of equity capital implied in analyst earnings forecasts and stock prices for a sample of 2,006 US firm-year observations belonging to controversial industry sectors (alcohol, tobacco, gambling, military, firearms, nuclear power, oil and gas, cement and biotechnology) during the period 1991-2012. The baseline regression model links CSR score to the implied cost of equity capital (ICC) and controls for firm-specific characteristics, industry factors and economic or market-wide factors. This model enables to capture the differential effect of CSR on ICC when the firm belongs to a specific sector of the controversial industries by adding an interaction term between CSR and the dummy variable representing this belonging.

The findings show two main results. First, CSR engagement significantly reduces the implied cost of equity capital (ICC) in all controversial industry sectors, taken as a group, as well as in each one of these sectors individually. Second, this effect is more pronounced when the firm belongs to the alcohol and tobacco industry sectors.

The findings have two important practical implications. First, they should increase managers’ confidence and incentives, in controversial industry sectors, to pursue CSR activities. Second, policymakers can encourage managers to undertake CSR initiatives in controversial industry sectors through tax incentives (e.g. reduce taxes for CSR related investment projects).

This paper extends prior studies that investigate the perceptions of capital market participants of firm’s CSR commitment (Sharfman and Fernando, 2008; Goss and Roberts, 2011; El Ghoul et al., 2011; Jo and Na, 2012; Bouslah et al., 2013) by examining the effect of CSR on ICC in the controversial industry sectors. It contributes to the debate around the relevance of CSR in controversial sectors by providing evidence of the reduction effect of CSR activities on ICC in controversial industries and by showing that this reduction impact is more pronounced when the firm belongs to alcohol, tobacco industry sectors.

In the last four years, since Volume I of this Bibliography first appeared, there has been an explosion of literature in all the main functional areas of business. This wealth of material poses problems for the researcher in management studies — and, of course, for the librarian: uncovering what has been written in any one area is not an easy task. This volume aims to help the librarian and the researcher overcome some of the immediate problems of identification of material. It is an annotated bibliography of management, drawing on the wide variety of literature produced by MCB University Press. Over the last four years, MCB University Press has produced an extensive range of books and serial publications covering most of the established and many of the developing areas of management. This volume, in conjunction with Volume I, provides a guide to all the material published so far.
