Abstract

Purpose

A conceptual model describes important factors within a system and how they relate to one another. They are important because they help to identify system changes that can yield the greatest improvement. Within information retrieval (IR), most research is directed towards multi-document retrieval and a multi-interaction IR user scenario. There are few, if any, IR conceptual models supporting minimal or single-interaction IR (siIR) user scenarios, however the need for siIR systems is growing rapidly. The purpose of this paper is to take the first step towards constructing a task-oriented conceptual model and experimental framework to support siIR research.

Design/methodology/approach

A first principles approach is employed to develop a task-oriented conceptual model, called bridging information retrieval (BIR). This model is contrasted with the concept of relevance, a central factor within IR research.

Findings

BIR introduces the central concept of bridging information (BI) as the objective of IR systems. BI is the additional information a user requires to complete a task, beyond their innate knowledge. The relationship between BI and relevance is determined.

Research limitations/implications

The theoretical basis of BIR is derived axiomatically; however the resulting system evaluation model is speculative.

Practical implications

The proposed operational framework offers researchers a systematic approach to designing and evaluating siIR systems.

Originality/value

This work contributes a novel task-oriented IR conceptual model and evaluation framework, both centred around the concept of BI for siIR. It also contributes a novel search task classification method.

Abstract

Purpose

Representative cultural heritage sites and monuments around the world have been lost or damaged by natural disasters, human conflicts and daily erosion and deterioration. Documentation and digital preservation by using three-dimensional (3D) modeling techniques enables to ensure the knowledge and access for future generations. Efficient working methods and techniques should be proposed for this purpose.

Design/methodology/approach

In this paper, a methodology for the generation of 3D photorealistic models of representative historical buildings is introduced, for using data are obtained using terrestrial laser scanning systems and photogrammetry.

Findings

In this paper, an approach to reconstruct 3D photorealistic models by using laser scanning and photogrammetric data is shown. Combination of data from both sources offers an improved solution for 3D reconstruction of historical buildings, sites and places. Integration of 3D models into virtual globes and/or software applications can ensure digital preservation and knowledge for next generations.

Research limitations/implications

Results obtained in a concrete building are shown. However, each building or studied area can show some other different drawbacks.

Practical implications

The study enables to generate 3D and four-dimensional models of most valuable buildings and contribute to the preservation and documentation of the cultural heritage.

Social implications

The study enables digital documentation and preservation of cultural heritage.

Originality/value

A proper solution at field (in a real and complicated case) is explained, in addition to the results, which are shown.

– The purpose of this paper is to learn from participants about their experiences managing type 1 and type 2 diabetes at work.

Abstract

Purpose

The purpose of this paper is to learn from participants about their experiences managing type 1 and type 2 diabetes at work.

Design/methodology/approach

Longitudinal, qualitative interviews with 45 individuals three times per year over three years focussed on views about disclosure; how they found or created support to manage their diabetes at work; and how they experienced the relationship between health and productivity.

Findings

Among participants, the presence of secondary conditions, such as fibromyalgia or vision loss, typically overshadowed the effect of diabetes at work. These conditions were often mentioned as the reason why a participant changed jobs, stopped working, or decreased work hours. Perspectives on disclosure were affected by the perception of stigma and discrimination, as well as the need for workplace accommodations. Overall, participants believed that the routine of a job and feeling useful benefited their health.

Research limitations/implications

The nature of the research was not medical and the paper did not collect participants’ medical records. The paper relied on self-report for diagnoses of diabetes and co-morbidities as well as unrelated health conditions. Although the participants lived in a variety of urban, suburban, and rural settings, the findings do not reflect the ways in which differences in geography may have influenced participants’ experience. A focus of future research might be the role played by geographic location in the experience of managing diabetes at work. Also, the majority of employed participants worked for small employers. Future research might include a focus on participants managing diabetes while working for larger employers, who may have greater resources and staffing to devote toward implementing changes in workplace policy.

Originality/value

The paper considers the preference that many participants have for working and being productive rather than not working, including those with secondary conditions as well as diabetes. The number of participants (n=45) is relatively large for a qualitative interview study. The longitudinal nature of the study allowed for a follow-along opportunity that yielded a rich source of data.

Abstract

Purpose

This paper aims to demonstrate the possibility of maintaining triple bottom line (TBL) sustainable performance in the petroleum industry via a case study. In particular, it presents the utilization of a lean-six-sigma (LSS) concept for investigating one of the underperforming support service activities in an engineering contractor (EC) and to indicate how LSS concepts enable the barriers to maintaining sustainable petroleum operations to be reduced for maintaining sustainable petroleum operations.

Design/methodology/approach

A case study has been carried out in an EC organization in relation to one of the support services (i.e. valves requisition process [VRP]) to demonstrate how LSS concepts enable the barriers to maintaining sustainable petroleum operations to be reduced for maintaining sustainable petroleum operations. Value stream mapping (VSM) and value stream analysis (VSA) have been utilized to investigate the barriers that inhibit sustainable operations. VSM and VSA have been performed to investigate the underperforming activities in the selected support service (i.e. VRP) using a current state map. After performing VSA, a future state map has been developed, indicating possible improvements in overall TBL sustainable performance.

Findings

VSM and VSA enable the barriers to maintaining TBL sustainable operations in the petroleum industry to be investigated, while minimizing waste in the ECs and asset owners’ organizations.

Research limitations/implications

The study has been limited to ECs’ support services, which have been delivered based on asset operators’ requirements.

Practical implications

The suggested LSS approach and related analysis help practicing engineers to perform similar analysis for different engineering support services. Improved performance in support service results minimize health, safety and environmental challenges in asset operations, and the resulting waste reduction increases the return on investments.

Social implications

Effective delivery of the assessments minimizes potential delays in projects related to petroleum operations, mitigating future accidents. It enhances the TBL sustainable performance of an asset-intensive industrial organization.

Originality/value

This manuscript addresses the inherent TBL sustainable performance challenges in the petroleum industry that have been caused by delayed projects. The responsibilities of projects’ delivery are mainly attributed to ECs. The EC organizations are operating in project mode, and projects delays are inherently caused by the frequently changing nature of: operators’ requirements; suppliers’ and/or manufacturers’ capabilities and restrictions; and lack of standardization in documentation and work processes (i.e. because of different engineering projects’ demands). Hence, this manuscript illustrates a methodology to demonstrate the possibility of TBL sustainable performance improvement in the petroleum industry via a case study (i.e. VRP-related project delivery performance improvement) in an EC organization utilizing the lean concept.
