Transportation infrastructure projects are inevitably delayed due to delays in the completion of underground utility relocation. Unfamiliar location, difficulty in utility identification and use of ineffective coordination practices hamper timely completion of utility relocation works. This paper aims to develop integrated road information modeling (RIM) and geographic information system (GIS) models to assist early identification of utilities and effective coordination during utility relocation in infrastructure projects.

An ethnographic action-based case study research methodology was adopted in this paper. Two ongoing infrastructure projects with significant utility relocation delays are chosen as case studies and integrated RIM-GIS models are developed to assist utility relocation. To verify the applications of developed RIM-GIS models, a focus group discussion was conducted with 10 field experts from the considered case studies.

The application of the developed RIM-GIS models enabled 3D visualization of existing underground utilities and enabled identification of utility conflicts before the start of the construction. They also enabled facilitating coordination and reduce utility relocation delays. The evaluation of the developed models shows that the RIM-GIS model approach enabled early planning and coordination and facilitates effective management of utility relocations.

The current practices of using CAD and GIS for utility relocations are inadequate due to the difficulties in characterizing utilities and ineffective coordination practices. The proposed RIM-GIS approach can be adopted as a suitable alternative for effective management of utility relocations.

Several studies have contributed toward integrating BIM and GIS for the analysis of highway and utility infrastructure projects. Efforts on integrating RIM and GIS for the support and management of utility relocations in highway and utility infrastructure projects remain unexplored.

Product variant design can only be achieved after all its constituent parts have been implemented by variant design. It is necessary to plan the sequence of part variant design reasonably. The product variant design process involves a large amount of information transfer events at the dimensional level. A reasonable product variant design process needs to make full use of the information transfer characters of parts to decrease the uncertainty of product variant design process. The existing methods of researching the product variant design process mainly focus on resource constraint and activity logic. They are deficient, however, in information transfer resolution and uncertainty management. This paper aims to address these issues.

This paper identifies the number of dimension transfer paths and the position of dimension locating within a transfer path as being the key factors affecting the information transfer role of dimension. Information transfer utility is proposed to measure the information transfer capability of dimensions and parts. Based on these, a two-stage approach of generating the sequence of part variant design based on information transfer utility is proposed.

The uncertainty of dimension constraint network is minimal during the product variant design process when parts are implemented by variant design under the sequence generated through a two-stage method based on the information transfer utilities of parts, as does the times of parameter transferring and iteration in dimension constraint network.

Part variant design under the sequence of descending information transferring utilities can decrease the difficulty of implementing product variant design validly and also increase the efficiency. This suggests an innovative method to planning the product variant design process reasonably from the perspective of informatics.

The relocation of existing underground utilities in urban environments is complex because of the existence of multiple utility agencies being responsible for numerous utilities and over constrained space and time to execute maintenance works. Unfamiliar location and insufficient records of maintenance data hamper the flow of work, causing unnecessary delays and conflicts. The aim of the paper is to explore 4 dimensional Building Information Modeling as a smart solution for the management of multiple utility data for a relocation project in an urban setting.

An empirical case-based research methodology is used to collect data and develop the BIM models. Two ongoing construction projects in an urban city are empirically studied, and 4D BIM models of identified utilities are developed to assist management and relocation of existing utilities.

The developed BIM models enabled the location of existing sub-surface utilities through 3D visualization and also enabled clash detection. The 4D simulation of BIM model enabled the tracking of actual progress of relocation works and thereby helped in taking necessary actions to minimize forthcoming delays. The evaluation of the developed model showed that the application of 4D BIM improved communication and coordination during utility relocation works.

4D BIM for utility infrastructure provides better management of utility information. They provide utility stakeholders an efficient way to coordinate, manage utility relocation processes through improved visualization and communication with a reduction in delays and conflicts.

Limited efforts were made using 3D BIM for sub-surface utility infrastructure in visualization and management of utility information. Efforts using 4D BIM in coordination and management of utility projects are left unexplored. This study adds value to the current literature through the application of 4D BIM for utility relocation projects.

The purpose of this paper is to examine how participation in an online health community provides for direct benefits in the form of information utility and social support and an indirect influence on perceptions of patient empowerment.

A multi‐method approach was conducted involving interviews with moderators of 18 online health communities and a field survey of 153 online health community participants.

Online health community participation leads to direct benefits in the form of information utility and social support and that information utility also helps to shape perceptions of patient empowerment among community participants.

This research calls into question the role of online health communities as a support mechanism to empower patients to take ownership over their healthcare treatment. Online health communities support the development of patient empowerment by creating and disseminating information that can be used to gain an understanding of a patient's health condition.

Purveyors of online health communities must be able to ensure a high level of engagement among community participants that allows for each member to elicit outcomes such as information utility, while simultaneously guarding against undesirable circumstances that may prohibit a positive experience.

Medical professionals can utilize the results of this study to develop strategies for incorporating online health communities into patient care. Specifically, medical professionals can use these results to identify relevant communities and engage in information sharing to ensure relevant and accurate information is disseminated to patients as they seek out information concerning their health conditions.

As an ever growing segment of the population looks to online health communities for health information seeking and emotional support, we still know very little as to the type of support that is provided by these forums and how benefits obtained from participation help to shape patient empowerment outcomes. This study determined that information utility and social support are two benefits obtained by online health community participants and that information utility also helps to shape perceptions of patient empowerment among community participants.

A growing amount of German and Austrian utilities create own Facebook accounts to communicate with their stakeholders. Whereas existing studies describe how utility companies are currently using Facebook, to the best of the authors’ knowledge, there exists no study which focuses on the actual expectations of Facebook users. Nevertheless, as the occurrence of social media redefined stakeholders’ expectations, research on the expectations of Facebook users become crucial. Therefore, the purpose of this paper is to contribute to the existing social media literature by investigating the expectations of Facebook users towards a virtual stakeholder dialogue with their public utility companies on Facebook.

Eight German and six Austrian public utilities supported the empirical study by posting a link to an online survey on their Facebook account. In total, 258 Facebook users followed that link and completed the survey.

The broad majority of participants expect public utility companies to use Facebook as a communication channel. They request to regularly receive a variety of information on different topics. In addition, participants want to have the opportunity to post general queries, complaints or criticism, suggestions for improvement, positive feedback or queries in a crisis situation. Moreover, the empirical data reveal that user-specific characteristics such as gender, age, country of residence, length of Facebook membership or number of Facebook friends impact the expectations towards a Facebook conversation.

The findings enable scholars and practitioners to gain in-depth insights into Facebook conversations from the actual user perspective.

The purpose of this paper is to study the optimal sequential information acquisition process of a rational decision maker (DM) when allowed to acquire n pieces of information from a set of bi-dimensional products whose characteristics vary in a continuum set.

The authors incorporate a heuristic mechanism that makes the n-observation scenario faced by a DM tractable. This heuristic allows the DM to assimilate substantial amounts of information and define an acquisition strategy within a coherent analytical framework. Numerical simulations are introduced to illustrate the main results obtained.

The information acquisition behavior modeled in this paper corresponds to that of a perfectly rational DM, i.e. endowed with complete and transitive preferences, whose objective is to choose optimally among the products available subject to a heuristic assimilation constraint. The current paper opens the way for additional research on heuristic information acquisition and choice processes when considered from a satisficing perspective that accounts for cognitive limits in the information processing capacities of DMs.

The proposed information acquisition algorithm does not allow for the use of standard dynamic programming techniques. That is, after each observation is gathered, a rational DM must modify his information acquisition strategy and recalculate his or her expected payoffs in terms of the observations already acquired and the information still to be gathered.

Dynamism has been the key to the success and popularity of social media, and users always try to adapt to the available new changes. Continuous growth in the access and reach of social media in the past decade has enabled the users to make a calculative assessment of their social media usage. Social currency is a phenomenon that helps the customer in their evaluation of social media usage. However, this concept is still in its infancy phase, and there have been hitherto no studies to understand the influence of social currency dimensions on Indian users. This paper aims to study the dimensions of social currency for a better insight into social media usage of Indian customers.

Data were collected from 384 respondents from the biggest residential university in Varanasi through a structured questionnaire using the snowball sampling technique. Responses were taken on a seven-point Likert scale. Responses were analyzed by the factor analysis method using the maximum likelihood estimation model.

The result of this study empirically demonstrated that six dimensions, i.e. conversation, information, utility, affiliation, advocacy and identity, constitute the social currency of the user while browsing social media sites. It was also found that among the factors described above, advocacy emerged as the most influential dimension of social currency for Indian users, followed by identity and affiliation.

The findings have various managerial implications for the firms that want to have a significant social media presence. These findings can help marketers to design a tailored social media campaign for Indian users in an efficient manner by successfully incorporating the aforesaid social currency dimensions in their strategy.

This study also reflects the societal impact of the dimensions of social currency on Indian users, as any change in the usage of social media can have a long-lasting effect on the mood of the people. The influence of the social currency dimension differs significantly in the context of Indian users compared to the existing literature, as they give more value to the behavioural aspect of the social currency (advocacy, identity and affiliation), strengthening the sense of belongings among the members.

This paper highlights, for the first time, the level of influence social currency dimensions have on Indian users, as there have been hitherto no studies to understand the influence of social currency dimensions on Indian users. Another significant contribution of this research is the empirical validation of the social currency determinants. Thus, this study may contribute to the social media strategy of the firm for Indian users by incorporating the social currency dimension, as discussed in the study.

This study explores information behavior and perception and vaccination among America's three largest ethnic minorities, Hispanic, Black/African American and Asian, in COVID-19 context. Information behavior and perception are investigated from cultural and demographic characteristics, while vaccination is explored from COVID-19 related information behavior and utility/value of COVID-19 vaccine information.

Using Qualtrics survey panel, a national survey of America's Hispanic, Black/African American and Asian population was conducted to better understand the impact of cultural and demographic factors on COVID-19 related information. Data were collected in Fall 2021. Multiple and logistic regression were conducted to analyze data.

Results show that cultural factors (i.e. cultural identity, social identity, social capital and religiousness) exert significant impact on information value and seeking across all three minority groups, while some demographic factors, Republicanism and age, also significantly predict COVID-19 related information seeking and value for Black/African Americans and Hispanics, but less for Asian Americans. Lastly, information value was found to significantly predict vaccine status, willingness and eagerness, the three facets of vaccination as conceptualized in this study, for top three racial/ethic minorities.

The finding of this study reveal that there are variations in terms of the level and type of attachment to one's culture/social group in COVID-19 informational context. Between the three groups, granular differences were observed regarding the relationship between cultural factors and perceived COVID-19 information value. While cultural identity is most associated with African Americans, social capital is most evident for the Asian Americans, but social identity was the strongest predictor among Hispanics. Thus, this study offers important strategic insights into a unique population sample to better understand the impact of COVID-19 related information perception and vaccination implication.

Information utilities like The Source and CompuServe reach an audience of well‐educated and affluent micro/personal computer users. These users can be served in the context of their business/professional roles. They can also be attracted to the utilities in their roles as individual consumers. Both The Source and CompuServe provide services that are directed to each of these user‐roles. However, the emphasis in the two utilities is somewhat different.

German, Austrian and Swiss utilities are confronted with radical changes in the European energy sector. A dialogue between the utility companies and their various groups of stakeholders is gaining importance. Increasingly, utilities create their own Facebook presence enabling such a dialogue. Still, to the best of the author’s knowledge there exists no research which explicitly focuses the stakeholder dialogue of German, Austrian or Swiss utilities on Facebook. Therefore, the purpose of this paper is to analyse Facebook as an instrument for dialogic communication in the energy sector.

An online survey was distributed to 1,280 German, Austrian and Swiss utilities, and 14 per cent of the utilities completed the survey, including 130 German, 19 Austrian and 25 Swiss companies. The participating utilities are primarily in public ownership.

The Facebook conversation of utility companies and their stakeholders meets the basic requirements of a virtual stakeholder dialogue. Nevertheless, less than half of the companies perceive their current stakeholder conversation on Facebook as truly interactive. Therefore, even if the basic requirements of a dialogue are met, most companies still do not seem to fully use the dialogue potential of Facebook.

This study provides first insights into virtual stakeholder dialogues in the energy sector. A suggestion to operationalise such a virtual dialogue is provided. Both operationalisation as well as the empirical results help researchers and practitioners to better understand virtual stakeholder dialogues.
