The purpose of this paper is to illustrate the current state of research on the significance of big data in and for corporate communication and to introduce a framework which provides specific connecting points for future research. This is achieved by summarizing and reviewing the insights provided by relevant articles in the most significant scholarly journals. The paper also investigates trends in the literature.

On the basis of a systematic literature review, 53 key articles from 2010 to 2015 were further analyzed.

The literature review illustrates the potentialities of big data for corporate communication, especially with regard to the field of marketing communication. It also reveals a dramatic lack of research in the fields of public relations and internal communication with respect to big data applications.

The online databases used in this paper comprised of refereed scientific journals with the highest impact factor in the respective disciplines. Journals with a lower impact factor and books were not included in the search process for this thematic analysis.

This paper provides a conceptual framework that describes four phases of strategic big data usage in corporate communication. The results show how big data is able to highlight stakeholders’ insights so that more effective communication strategies can be created.

This paper brings together previously disparate streams of work in the fields of communication science, marketing, and information systems with respect to big data applications in corporate communication. It represents the first attempt to undertake a systematic and comprehensive interdisciplinary overview of this kind.

This paper aims to investigate the wear behaviour of different materials for cylinder liners and piston rings in a linear reciprocating tribometer with special focus on the wear of the cylinder liner in the boundary lubrication regime.

Conventional nitrided steel, as well as diamond-like carbon and chromium nitride-coated piston rings, were tested against cast iron, AlSi and Fe-coated AlSi cylinder liners. The experiments were carried out with samples produced from original engine parts to have the original surface topography available. Radioactive tracer isotopes were used to measure cylinder liner wear continuously, enabling separation of running-in and steady-state wear.

A ranking of the material pairings with respect to wear behaviour of the cylinder liner was found. Post-test inspection of the cylinder samples by scanning electron microscopy (SEM) revealed differences in the wear mechanisms for the different material combinations. The results show that the running-in and steady-state wear of the liners can be reduced by choosing the appropriate material for the piston ring.

The use of original engine parts in a closely controlled tribometer environment under realistic loading conditions, in conjunction with continuous and highly sensitive wear measurement methods and a detailed SEM analysis of the wear mechanisms, forms an intermediate step between engine testing and laboratory environment testing.

Despite an impressive body of international research, there is a lack of empirical evidence describing the ways in which organisational environments influence the practices of corporate communications (CC). A cross-cultural survey in five countries contributes to closing this research gap. The paper aims to discuss this issue.

What makes the research design innovative is that the questionnaire incorporates both practitioners’ perceptions of the cultural context and the relevance of CC practices. The sample comprises 418 practitioners from the most senior positions in CC in the biggest companies in Australia, Austria, Germany, Indonesia, and Switzerland. By choosing a systematic access to the field the authors circumvent shortcomings of “snowball” sampling techniques.

While cultural perceptions and CC priorities vary to a certain degree, there are hardly any significant correlations between the two. Meanwhile, the “nation variable”, and the institutional settings associated with it, are more instructive when explaining differences in CC.

A large cross-cultural survey needs to take a “birds eye view” and, as such, is able to identify only general tendencies when describing relations between perceptions of culture and CC practices. Future case studies and qualitative research could explore more subtle ways in which CC is influenced not only by the cultural context, but also – and probably even more – by institutional environments.

This is the first cross-cultural survey to systematically describe on the level of primary data, the links between CC practices and perceptions of the organisational environment. Since the results indicate only a limited impact of culture, the authors would recommend the rehabilitation of the “nation variable”. Provided it is understood and differentiated as a representation of specific institutional contexts, the nation variable is likely to prove highly instructive when accounting for the diversity of CC observed around the world.

Adopting a quantitative explorative research design, we employed a sample of 770 foreign market entries in the period 2005–2015 to investigate whether particular entry mode strategies such as joint venture or wholly owned subsidiary are differently chosen by small- and medium-sized enterprises (SMEs) and large firms. Various tests have been carried out revealing that SMEs show some different features compared to large firms when selecting their entry mode. SMEs react differently to economic downturns, and the diversification level is a crucial determinant for their entry choices while it is not for large firms. Moreover, we found for a set of other factors affecting the entry choice of large firms, not being significant for SMEs. Implications of these findings are discussed.

The purpose of this paper is to propose the Collaborative Search System that attempts to achieve collaboration by implicitly identifying and reflecting search behaviour of collaborators in an academic network that is automatically and dynamically formed. By using the constructed Collaborative Hit Matrix (CHM), results are obtained that are based on the search behaviour and earned preferences of specialist communities of researchers, which are relevant to the user's need and reduce the time spent on bad links.

By using the Digital Bibliography Library Project (DBLP), the research communities are formed implicitly and dynamically based on the users’ research presence in the search environment and in the publication scenario, which is also used to assign users’ roles and establish links between the users. The CHM, to store the hit count and hit list of page results for queries, is also constructed and updated after every search session to enhance the collaborative search among the researchers.

The implicit researchers community formation, the assignment and dynamic updating of roles of the researchers based on research, search presence and search behaviour on the web as well as the usage of these roles during Collaborative Web Search have highly improved the relevancy of results. The CHM that holds the collaborative responses provided by the researchers on the search query results to support searching distinguishes this system from others. Thus the proposed system considerably improves the relevancy and reduces the time spent on bad links, thus improving recall and precision.

The research findings illustrate the better performance of the system, by connecting researchers working in the same field and allowing them to help each other in a web search environment.

Civil society organisations (CSOs) contribute essentially to welfare states and society. In Europe they play a key role in the provision of social services, but also fulfil a large variety of other functions, such as giving voice to unaddressed issues, offering alternative ways of occupational socialisation or facilitating social inclusion (cf. Kramer, 1981; Rose-Ackerman & James, 1986; Kendall, 2003). Current research suggests that the third sectors’ societal roles considerably vary between countries, depending on the welfare state they are embedded in: Starting with a revision of Esping-Andersen's welfare regime typology (1990) and also based on the earlier work of Moore (1966), Salamon and his colleagues developed a typology of four different ‘non-profit regimes’ (Salamon & Anheier, 1998; Salamon, Hems, & Chinnock, 2000a). As key dimensions for this classification, they applied the extent of governmental welfare spending and the size of the third sector (cf. Johnson, 1999). According to this typology of nonprofit regimes, in countries with a large third-sector CSOs mainly fulfil the service function. Countries with a relatively small third sector, so the implicit conclusion, would tend to engage in ‘the expression of political, social, or even recreational interests’ (Salamon & Anheier, 1998, p. 229).

Transformation of smallholder agriculture from subsistence to more commercially-oriented production is one of the strategies advocated for improving rural households' food security and general welfare. The purpose of this paper is to assess potential differential effects of smallholder commercialization intensity on the different dimensions of food security.

Using household data from rural Tanzania, the study employed Tobit regression and Generalized Propensity Score (GPS) approaches to analyze smallholder commercialization intensity and associated food security effects.

Results show that smallholder commercialization has heterogeneous effects on the different dimensions of food security. Specifically, lower levels of commercialization are associated with lower food availability, access, utilization and stability. At higher intensities of commercialization, smallholders have higher food availability and access but modest improvements in food utilization and stability. Findings suggests that heterogeneous effects of commercialization on food security and the multi-dimensional nature of food security are important aspects to consider in the design of strategies to improve smallholder agriculture for enhanced food security and welfare.

It is important to point out that while food security is still a complex phenomenon, one that cannot be analyzed easily, so is commercialization. This study has used only one of the many definitions of commercialization.

Most existing literature on smallholder commercialization groups farmers into commercial and subsistence-oriented households. However, smallholders commercialize at various levels of intensity. This paper, conversely, analyzes the potential effects of different levels of commercialization on the various aspects of food security. Further, unlike extensive literature that focus on a narrow definition of food security, this paper expands the evidence of the implications of smallholder commercialization on the different dimensions of food security namely, food availability, access, utilization and stability.

This paper aims to provide a comprehensive review of research on robotics in travel, tourism and hospitality, and to identify research gaps and directions for future research.

This paper analyzes 131 publications published during 1993-2019, identified via Scopus, Web of Science, ResearchGate, Academia.edu and Google Scholar. It offers quantitative analysis of frequencies and cross-tables and qualitative thematic analysis of the publications within each of seven identified domains.

The paper identifies “Robot,” “Human,” “Robot manufacturer,” “Travel/tourism/hospitality company,” “Servicescape,” “External environment” and “Education, training and research” as the research domains. Most research studies are dedicated to robots in restaurants, airports, hotels and bars. Papers tend to apply engineering methods, but experiments and surveys grow in popularity. Asia-Pacific countries account for much of the empirical research.

The analysis was limited to publications indexed in four databases and one search engine. Only publications in English were considered. Growing opportunities for those who are anxious to publish in the field are identified. Importantly, emerging research is branching out from the engineering of robots to the possibilities for human/robot interactions and their use for service providers, opening up new avenues of research for tourism and hospitality scholars.

The paper identified a myriad of application areas for robots across various tourism and hospitality sectors. Service providers must critically think about how robots affect the servicescape and how it needs to be adjusted or re-imagined to ensure that robots and employees can augment the service experiences (co-)created within it.

This is the first study to systematically analyze research publications on robotics in travel, tourism and hospitality.

To establish a statistical formulation of robust design optimization and to develop a fast optimization algorithm for the solution of the statistical design problem.

Existing formulations and methods for statistical robust design are reviewed and compared. A consistent problem formulation in terms of statistical parameters of the involved variables is introduced. A novel algorithm for statistical optimization is developed. It is based on the unscented transformation, a fast method for the propagation of random variables through nonlinear functions. The prediction performance of the unscented transformation is demonstrated and compared with other methods by means of an analytical test function. The validity of the proposed approach is shown through the design of the superconducting magnetic energy storage device of the TEAM workshop problem 22.

Provides a consistent formulation of statistical robust design optimization and an efficient and accurate method for the solution of practical problems.

The proposed approach can be applied to all kinds of design problems and allows to account for the inevitable effects of tolerances and parameter variations occuring in practical realizations of designed devices.
