To measure the exact size of the world wide web (i.e. a census). The measure used is the number of publicly accessible web servers on port 80.

Every IP address on the internet is queried for the presence of a web server.

The census found 18,560,257 web servers.

Any web servers hidden behind a firewall, or that did not respond within a reasonable amount of time (20 seconds) were not counted by the census.

Whenever a server is found, we download and store a copy of its homepage. The resulting database of homepages is a historical snapshot of the web which will be mined for information in the future.

Past web surveys performed by various research groups were only estimates of the size of the web. This is the first time its size has been exactly measured.

This paper aims to provide a limited, but selective bibliography on modelling heat and mass transfer in composite fluid‐porous domains.

Since the pioneer study by Beavers and Joseph, the problem of interface continuity and/or jump conditions at a fluid‐porous interface has been of interest to the fluid mechanics and heat and mass transfer community. The paper is concerned both with numerical simulations of heat and fluid flow in such systems, and with the linear stability problems.

The one‐ and two‐domain formulations are equivalent. Using the Darcy‐Brinkman extension instead of the Darcy model reduces the number of ad hoc parameters in this configuration.

The problem of double diffusive convection has still to be solved and analyzed.

The discussion on the interface conditions is of great relevance to many industrial and practical situations.

The important question of the macroscopic formulation of the problem is tackled in the paper.

This study aims to reflect on ways that the experiences of vulnerable users of drug and alcohol services can inform social work practice and policy to improve treatment engagement and mitigate negative responses to interventions.

The research used semi-structured interviews and photovoice in an interpretative phenomenological analysis of the experiences of people in treatment for drug or alcohol problems whose child was the subject of a Child Protection or Child in Need order.

The research gave insights into participants’ experiences of loss of control, unfairness and stigma. Participants described how they felt powerless in the social services system and were afraid to be open and honest with practitioners for fear of having their children removed.

The research highlighted the need for more training and professional development for social work practitioners to address power imbalance issues, and the need to promote non-threatening professional practice that removes penalties for disclosure of substance use, enabling substance users who are parents to be more honest about their drug use.

The research showed the value of phenomenological methods for investigating sensitive issues with vulnerable users of treatment services in a way that can inform policy and practice.

This paper explores ways that phenomenological research with vulnerable, hard-to-reach participants can produce insights about the potential benefits of social work practice that is non-threatening and encourages greater openness and honesty among substance users who are parents.

This study aims to present a bibliometric overview of articles published in the field of tourism, leisure and hospitality and analyzed by researchers mainly affiliated with European institutions.

The authors conducted a bibliometric study of journals included in the Web of Science related to the field of tourism, leisure and hospitality in 2019. The review incorporates various techniques to determine the field’s structure from a scientific and intellectual perspective.

The results are valuable for several reasons. First, they will support researchers in identifying those topics with the greatest potential for advancing research in this field. Second, they will constitute an important aid in the design of new policies for journal publishers.

This study can lead to advances in the tourism, leisure and hospitality field, as it identifies the publication trends of researchers who are mainly affiliated with European institutions. It also offers useful information for practitioners and academics in their endeavor to identify gaps in the extant literature and future trends.

No other studies have analyzed this field for a period of this length.

The purpose of this paper is to advance knowledge about organization‐public relationships by establishing a theoretical category for understanding them and by contributing to a foundation of knowledge in that category. Relationship stresses are presented as the factors that constrain organization‐public relationships. This study identifies stresses on the relationship between a grassroots advocacy organization and its former members, as well as stresses between the organization and members who have decreased their participation in it.

In‐person interviews were conducted with 24 people, phone interviews were conducted with 44 people, and e‐mail interviews were conducted with 13 people. Interviewees included staff members, former volunteers, and volunteers who had decreased their participation in the organization.

Several relationship stresses were identified: the silver curtain, the emotion tax, relationship speeding, invisible isms, weak leadership, disagreement with decisions, the revolving door, overworking volunteers, underworking volunteers, age, and health.

This study contributes a new category for relationship management scholarship, which can be productive for theory building. It also illuminates Dozier and Lauzen's questioning about the unique conditions of social movement organizations.

Established cultivation strategies can actually aggravate publics when a relationship has significantly deteriorated and the root problem is not addressed.

Recognizing problems in the relationship between an advocacy organization and members results in a deep understanding of a unique context for public relations practice. In addition, this study illuminates a context for cultivation strategies by codifying a foundation of relationship stresses. Identifying stresses to relationships can help scholars and practitioners ascertain problems and treat those problems at the root level.

The purpose of this paper is to challenge service researchers to design for service inclusion, with an overall goal of achieving inclusion by 2050. The authors present service inclusion as an egalitarian system that provides customers with fair access to a service, fair treatment during a service and fair opportunity to exit a service.

Building on transformative service research, a transformative, human-centered approach to service design is proposed to foster service inclusion and to provide a platform for managerial action. This conceptual study explores the history of service exclusion and examines contemporary demographic trends that suggest the possibility of worsening service exclusion for consumers worldwide.

Service inclusion represents a paradigm shift to higher levels of understanding of service systems and their fundamental role in human well-being. The authors argue that focused design for service inclusion is necessary to make service systems more egalitarian.

The authors propose four pillars of service inclusion: enabling opportunity, offering choice, relieving suffering and fostering happiness.

Service organizations are encouraged to design their offerings in a manner that promotes inclusion and permits customers to realize value.

This comprehensive research agenda challenges service scholars to use design to create inclusive service systems worldwide by the year 2050. The authors establish the moral imperative of design for service inclusion.

This editorial introduces a special issue of the Journal of Services Marketing, dedicated to papers discussing the effect of the physical context on customer experience. This study aims to identify diverse areas of extant knowledge, upon which researchers might draw when investigating the effect of the physical context on customer experience, to inform future research agendas.

Drawing on available literature, the authors argue that, as prior studies in diverse scholarly fields have explored the physical context, these bodies of knowledge may offer theories and constructs that meaningfully inform explorations of the effect of the physical context on customer experience.

The authors identify five marketing subdisciplines and six nonmarketing disciplines, each offering theories, constructs and perspectives which researchers might draw upon in future studies of the effects of the physical context on customer experience.

The authors develop a novel map which depicts the field of study of the effects of the physical context on customer experience, which scholars might use to inform future research design. In addition, the authors suggest several directions for future research.
