Using Travelpod.com, this paper aims to provide a methodology to locate central groups of travelers and to describe pattern characteristics of central travelers.

The paper uses snowball sampling to locate travelers and analyze their hyperlink interconnections to identify central travelers' groups. Analysis of the adjacency matrix of the social network of travelers using multidimensional scaling and hierarchical cluster analysis to identify core travelers' groups follows.

In total, 7 percent of travelers are considered central travelers. They form core groups containing the most active and information providing travelers. Group membership is correlated with common travelers' characteristics.

The research is limited to a specific network of travelers, to a specific time interval, and to a specific sampling method. Repetition of the study in other travelers' networks in several time instances using a full list of member travelers would help to generalize the findings. Also, graph theoretical approaches other than the statistical analysis used could reveal more properties.

Travelers in core groups are more likely to be reached by others who navigate through a series of incoming links that lead to them and it is probable that these travelers have the potential to address many visitors and therefore to have a significant impact on the provision of information.

The originality of the paper lies in the use of multivariate statistics on the network adjacency matrix to locate core travelers groups and on finding groups of the most influential travelers.

The purpose of this paper is to consider organisational climate as the vehicle to get an understanding, map and enhance the appropriate organisational culture for good clinical governance (CG). Based on this assertion, the purpose of this research is fourfold: to investigate CG attributes embedded in Greek hospitals' climate; to test the validity and reliability of the Clinical Governance Climate Questionnaire (CGCQ) and highlight the dimensions of CG climate in the Greek context; to illuminate the “red flag” aspects of hospital's climate and areas shaping the perceptions of the quality of the provided services; and to explore the influence of hospital's legal status on CG climate and service quality.

Empirical research using the CGCQ was conducted in three Greek NHS hospitals. A total of 214 usable questionnaires completed by the hospitals' personnel were gathered.

The validity and reliability tests proved that the study's five‐dimension structure of CGCQ is capable of conceptualising the basic elements of CG climate in the Greek context. Hospital's climate was found to be not supportive to successful CG implementation, and areas that demand attention were illuminated. Hospital's legal status seems to mediate CG climate and service quality.

CGCQ proved to be a useful tool for managers and policymakers to trace “problematic” areas of hospital's climate and develop strategies for successful CG initiatives.

The paper contributes to the field of health care management, since it demonstrates that CG climate can be used as a “gauge” of the prevailing CG culture. CGCQ is revealed as a valid, reliable and flexible tool.
