Abstract

Purpose

Light field images (LFIs) have gained popularity as a technology to increase the field of view (FoV) of plenoptic cameras since they can capture information about light rays with a large FoV. Wide FoV causes light field (LF) data to increase rapidly, which restricts the use of LF imaging in image processing, visual analysis and user interface. Effective LFI coding methods become of paramount importance. This paper aims to eliminate more redundancy by exploring sparsity and correlation in the angular domain of LFIs, as well as mitigate the loss of perceptual quality of LFIs caused by encoding.

Design/methodology/approach

This work proposes a new efficient LF coding framework. On the coding side, a new sampling scheme and a hierarchical prediction structure are used to eliminate redundancy in the LFI's angular and spatial domains. At the decoding side, high-quality dense LF is reconstructed using a view synthesis method based on the residual channel attention network (RCAN).

Findings

In three different LF datasets, our proposed coding framework not only reduces the transmitted bit rate but also maintains a higher view quality than the current more advanced methods.

Originality/value

(1) A new sampling scheme is designed to synthesize high-quality LFIs while better ensuring LF angular domain sparsity. (2) To further eliminate redundancy in the spatial domain, new ranking schemes and hierarchical prediction structures are designed. (3) A synthetic network based on RCAN and a novel loss function is designed to mitigate the perceptual quality loss due to the coding process.

Abstract

Purpose

The purpose of this paper is to investigate the link between integrated thinking (IT) and integrated reporting (IR) in a global player. It seeks to shed light on how IT develops organically, using their IR as a source. Bourdieu’s theory of practice is utilised to explain the concept of IT and how it is established in the case organisation through publicly available corporate information.

Design/methodology/approach

Video, document/text and interview material are used to investigate the perception and status quo of IT at the case organisation. Data were analysed in two coding stages to derive at the categories/themes that have the most explanatory power regarding the phenomenon under study.

Findings

The study contributes the organisational habitus of handling uncertainty and disruption, which governs the IT and IR initiative and development in the case organisation. Furthermore, it illustrates an empirical example of how an organisation has grown its IT approach over time and has introduced IR as a result of that, as a reflection on the IT approach.

Originality/value

This paper investigates a global organisation, the first provider of an integrated report in their geographical region, and its IT and reporting approach. The findings reflect on the organisational habitus of handling uncertainty and disruption, which leads to IT and ultimately IR. The case organisation constitutes a “natural integrated thinker” in their agile asset-light approach to their business and their integration of stakeholders beyond the organisation. They are the regional vanguard of sustainability and integration, as a result of which they have become one of the few global players of their region.

Abstract

A number of over‐lapping terms have been applied to coding techniques used in association with post‐co‐ordinate indexing. These include subcodes, which can be interpreted as the generic term; superimposed, graphic and random coding and Zatocoding, which are nearly synonymous; and partial or derived coding: the last named may be considered as a bridge between the second group (superimposed, etc.) and direct coding techniques. For the sake of consistency, the terms graphic coding and partial coding will be employed wherever possible. The general principles of coding have been adequately reviewed in C. P. Bourne's Methods of Information Handling and have been subjected to detailed analysis in J. L. Jolley's Data Study. Graphic codes have been studied in considerable depth in the above; therefore, a brief introduction will suffice.

Abstract

Purpose

The Accounting Information Systems (AIS) research field emerged around 30 years ago as a subfield of accounting but is at risk to develop further as an isolated discipline. However, given the importance of digitalization and its relevance for accounting, an amalgamation of the parent research field of accounting and the subfield of accounting information systems is pivotal for continuing relevant research that is of high quality. This study empirically investigates the distance between AIS research that is included in accounting literature and AIS research that prevails in dedicated AIS research outlets.

Design/methodology/approach

To understand which topics define AIS research, all articles published in the two leading AIS journals since 2000 were analyzed. Based on this topical inventory, all AIS studies that were published in the top 16 accounting journals, also since 2000, are identified and categorized in terms of topic, subtopic and research methodology. Next, AIS studies published in the general accounting field and AIS studies published in the AIS field were compared in terms of topics and research methodology to gain insights into the distance between the two fields.

Findings

The coverage of AIS topics in accounting journals is, to no small extent, concentrated around the topics “information disclosure”, “network technologies” and “audit and control”. Other AIS topics remain underrepresented. A possible explanation might be the focus on archival studies in accounting outlets, but other elements might play a role. The findings suggest that there is only a partial overlap between the parent accounting research field and the AIS subfield, in terms of both topic and research methodology diversity. These findings suggest a considerable distance between both fields, which might hold detrimental consequences in the long run, if no corrective actions are taken.

Originality/value

This is the first in-depth investigation of the distance between the AIS research field and its parent field of accounting. This study helped develop an AIS classification scheme, which can be used in other research endeavors. This study creates awareness of the divergence between the general accounting research field and the AIS subfield. Given the latter's relevance to the accounting profession, isolation or deterioration of the AIS research must be avoided. Some actionable suggestions are provided in the paper.

Abstract

Organisations either keep spares for their own use, or‐for‐sale to other organisations. In either case, the ultimate need is to be able to replace worn or defective parts in operational machinery or equipment. In an economic sense, spares are kept to meet the needs of the situation in the cheapest way.

Abstract

Purpose

The purpose of this paper is to identify and design the axial coding pattern of the factors affecting the unplanned use behavior of users of the academic libraries and information centers.

Design/methodology/approach

The study as an applied research with a qualitative approach employed the grounded theory. The data collection tool was a deep and semi-structured interview. The interviews data were analyzed and coded during three stages of open, axial and selective coding using the MAXQDA 10 qualitative analysis software. The research population consisted of faculty members and experts in three areas of library and information science, management and psychology. Using the combined targeted sampling method (targeted and then the snowball), 12 subjects were selected as the sample size.

Findings

According to the research findings, the factors affecting the unplanned behavior of users in the use of academic libraries resources and services were identified as factors related to technology, environmental factors, information resources, information services, human resources, individual features, time position factor, cultural factors and social factors. Accordingly, the axial coding pattern of this type of behaviors was designed.

Research limitations/implications

The research limitations include the lack of theoretical basis related to the unplanned behavior issue in the field of library and information science and the lack of full familiarity of most of the experts in the field of library and information science with this topic. These factors lead to the necessity of explaining the subject under discussion.

Originality/value

The unplanned behavior of clients can be utilized to persuade users to use the information resources and library services so that the costs spent on their preparation and collection will be justifiable. The current research addressed this aspect of the unplanned information-seeking behavior.
