Abstract

For the first time since the “limits to growth” debate of the 1970s, we hear serious talk about the prospect of the world running out of oil. In the United States, concerns about reducing dependence on foreign oil have incited debate over the viability of alternative energy sources versus the oil industry's search for new oil “frontiers.” The rancorous dispute over drilling in the Arctic National Wildlife Refuge (ANWAR) has captured the spotlight in this debate. Less controversial, but more significant for the future of U.S. oil production, are the bountiful “deepwater” reserves of the Gulf of Mexico (GOM). Offshore is central to the history of the petroleum industry over the last 50 years, and the GOM is the most explored, drilled, and developed offshore petroleum province in the world. In recent decades, revenue from offshore leasing has been second only to federal income taxes in value to the U.S. treasury. During the last 30 years, the search for oil and gas has continually moved into deeper waters and into new offshore environments. Still, the GOM remains the primary laboratory for technological innovation and regulatory practices. The recent and spectacular revival in production there thanks to deepwater discoveries has strongly reinforced this demonstration effect. As offshore oil assumes a high profile in national development strategies around the world, any effort to analyze the political, social, and economic aspects of offshore exploration and development must use the GOM as a historical precedent or basis of comparison.

Abstract

Purpose

The primary purpose of this paper is to present an integrated framework for user interface prototyping and evaluation for the development of information systems and to present architecture for evaluating generic applications.

Design/methodology/approach

The framework is constructed through combining two distinctive methods of prototyping and evaluation, statechart and goals, operators, methods, and selection rules. Relevant methods and architectures of the integrated framework are presented in unified modeling language when possible.

Findings

The importance of the usability of information systems is highlighted in this research. However, it still lacks an integrated framework for information system development and usability evaluation. This paper provides a framework that evaluation method is intertwined with user interface prototyping to shorten the time of development lifecycle. The architecture for evaluating generic applications is also invaluable for motion and time study and the procurement of vender‐provided systems.

Research limitations/implications

The user base of information systems is diverse and the requirements of these systems change over time. This paper provides a framework that helps managers and engineers smooth and shorten the development phases. For future works, an object‐oriented programming framework and a tool for evaluating generic applications will be developed.

Originality/value

This paper proposes a comprehensive framework for combining prototyping and evaluation, as well as architecture for the evaluation of generic applications. It shortens the development phases by using formal modeling for user interface construction and evaluation. It also provides means to evaluate candidate systems whose program logics cannot be accessed and modified. It also complements the models used in the framework by extending their practical and academic values.

Abstract

Purpose

The purpose of this paper is to identify the importance of commuting time in the turnover intentions of Korean employees. This study also examines the impact of unsolicited job offers and working in the Seoul metropolitan area to elucidate the role of commuting time in determining turnover intentions.

Design/methodology/approach

The present study used two waves of the Graduates Occupational Mobility Survey, a large-scale survey of Korean employees. Binary logistic regression analyses were used to test the research model on 11,469 and 11,587 Korean employees in 2012 and 2013, respectively.

Findings

The commuting time increases turnover intentions, as do unsolicited job offers and working in the Seoul metropolitan area. Unsolicited job offers increase the turnover intentions of Korean employees more when they suffer from longer commutes, especially if they work in the Seoul metropolitan region.

Research limitations/implications

The study highlights the role of commuting time as resource loss that diminishes employees’ ability to cope with their job demands, which can be a predictive variable for turnover intentions. This study also considers unsolicited job offers and the Seoul metropolitan area as increasing ease of movement, elucidating the process through which commuting time is related to turnover intentions.

Originality/value

The present study adopts the resource conservation and ease-of-movement concepts to increase the understanding of the complexity of commuting time in determining turnover intentions.

Abstract

Purpose

The offshore supply vessel (OSV) industry is critical to offshore oil and gas operations around the world and contributes to the economic and ecological impacts experienced by the local communities supporting the offshore oil and gas industries. The OSV industry has not been studied significantly and the economic and ecological impacts to local communities is generally unknown. This paper aims to address these issues.

Design/methodology/approach

In this paper, the authors review the activities and logistical requirements involved in offshore exploration and development with special attention paid to workflows and the manner in which service vessels are utilized in the Gulf of Mexico. The authors estimate the OSV needs per stage of activity for offshore operations based on data collected from company planning documents, fleet utilization data from oil and gas companies and service providers, interviews and surveys. The statistical data is synthesized and reconciled and despite large variances the data sources are in reasonable agreement. Empirical data on circuit factors are also provided. The applications and limitations of the analyses are discussed.

Findings

In the US GOM, a large variety of marine vessels transport goods and provide services to exploration, development and production activity. OSVs provide a vital link between offshore E&P activities and shore‐based facilities. Offshore oil and gas operations cannot function without them and their utilization and spatial distribution provide a way of understanding the impacts of the offshore oil and gas industry on coastal communities.

Originality/value

This is the first empirical analysis of any offshore service vessel industry. The data presented here can be used to predict the environmental, economic, public health, and infrastructural consequences of alternative offshore development policies.

Abstract

Purpose

The purpose of this paper is to identify demographic differences based on how users interact with web applications. The research is needed to develop future systems able to adapt the representation of online information to the user’s specific needs and preferences improving its usability. The following question guides this quest: is there a direct relationship between age and/or gender and interaction?

Design/methodology/approach

GOMS (goals, operators, methods, and selection rules) analysis was used to reduce complex interaction tasks into basic operators like pointing, dragging, typing, etc. An experiment was designed to analyse the user performance in the use of these operators through five complex tasks: point-and-click, drag-and-drop, text selection, text edition and menu selection. The sample comprises 592 individuals which took part in the experiment. The performance was analysed using multivariate regression analysis. User laterality and the the user experience were used as control variables.

Findings

The factors studied are significant enough to support user classification. The analysis evidenced that men performed significantly better than women when executing interaction pointing and dragging GOMS’s operators, but no significant differences arose with regard to the performance in the typing operators. Older users performed worse in all the interaction tasks. No significant performance differences were detected between left and right-handed users.

Research limitations/implications

The study pretends to lay the ground for developing artificial intelligence-based classification systems (e.g. neural networks, decision trees, etc.) able to detect significant differences in user performance, classifying users according to their age, gender and laterality.

Practical implications

This user profiling would drive the organisation, selection and representation of the online information according to the specific preferences and needs of each user. This would allow the design of new personalisation algorithms able to perform dynamic adaptation of user interfaces in order to improve the usability of online information systems.

Originality/value

This work extends previous research on user performance under a new approach and improved accuracy. First, it relies on the combined and simultaneous analysis of ageing and gender and the use of user laterality and experience as control variables. Second, the use of the GOMS analysis allowed the design of tests that closely resemble the user interaction in online information systems. Third, the size of the sample used in this analysis is much bigger than those used in previous works, allowing a more thorough data analysis which includes the estimation of an advanced model which is quantile regression.

Abstract

Purpose

The purpose of this paper is to study suitable visualization techniques representing Qur'an history and atlas. It focuses on analyzing the effectiveness of the concept map and the hyperbolic tree visualization techniques.

Design/methodology/approach

The effectiveness is measured in the aspects of the task time to complete a search based on questions provided. The task time is predicted using a task analysis technique called keystroke level model – goal operator methods and selection rules (KLM-GOMS). It is suitable to produce the hypothesis of which visualization techniques are able to maneuver the users to complete the task goals in the shortest time. The scope presented is the histories and locations related to selected chapters in part 30 of the Qur'an.

Findings

Hyperbolic tree is more time effective compared with concept map visualization technique. Concept map visualization system has been voted as the most satisfying visualization technique even though the difference is only 1.3 seconds. The more important aspect for this analysis is the presentation of the information. Information should be presented clearly rather than hidden although the hidden function should be provided for users to use. However, both techniques are predicted to support conceptual understanding.

Research limitations/implications

The focus of the analysis was data structure and how to get to the right nodes before retrieving the final output.

Social implications

Assisting developers of Qur'anic systems therefore improves the effectiveness of users of Qur'anic system in finding information.

Originality/value

Analysis on visualization techniques in context Qur'an history and atlas using KLM-GOMS study in terms of locations that lead to the birth of various chapters in Qur'an is rarely being discussed. Previous studies focus on development and implementation of textual Qur'an systems while this study focuses on user analysis using techniques mentioned above.

Abstract

Purpose

The purpose of this paper is to present coordinate measuring system possibilities in the meaning of the geometric accuracy assessment of hot zone elements in aircraft engines. The aim of the paper is to prove that this method, which uses blue light and is most sufficient and cost-saving method, can to be used in the production line for serial manufacturing of elements, for which a high level of accuracy is required.

Design/methodology/approach

The analysis of the geometric accuracy of the blades was performed using non-contact optical coordinate scanner ATOS Triple Scan II Blue Light, manufactured by GOM Company, at the Department of Mechanical Engineering, Rzeszów University of Technology. Geometric analysis was conducted for blades manufactured from different waxes (A7Fr/60 and RealWax VisiJet CPX200), thus comparing injection technique and rapid prototyping (RP) method, and for casting made of Inconel 713C nickel-based superalloy.

Findings

The analysis of the criteria for the method of blades’ measuring selection showed that the chosen system successfully met all criteria for the verification of blades’ geometry at the selected stages of the process. ATOS II optical scanner with blue light technology allows measurement almost regardless of daylight or artificial (white) light. This allows the application of the measurement system in the production cycle, thus eliminating the need to create special conditions for measurements.

Practical implications

Requirements related to the accuracy of measured values, diversity and allowable measurement time are linked with the methods of production. Modern manufacturing methods based on computer-aided design systems/manufacturing/engineering systems require a non-contact optical measurement method based on the computer-aided-based coordinate measuring technique. In case of the non-contact optical scanning method based on the ATOS GOM measuring system, time and measurement costs depend on the methodology of measurement and the possibility of its automation. This is why the presented paper has a practical impact on possibilities for the automation of geometric accuracy measurements of obtained elements in the series production line.

Social implications

The use of ATOS Triple Scan II Blue Light by GOM Company allows the reduction of cost and time of production because of the possibility of the introduction of this system in an automated production line. Additionally, the measurement of hot section blades of aircraft engines by using the blue light method is much more accurate and has implication as it impacts safety of further used manufactured elements.

Originality/value

This paper presents the possibility of using the ATOS Triple Scan II Blue Light measuring system for geometric accuracy measurements in case of hot section blades of aircraft engines. This research is original because it describes three model geometric accuracy measurements, wax model obtained using the injection technique, wax model obtained using the I RP process and casting made of Inconel 713C nickel-based superalloy.

Abstract

Understanding when new forms will emerge constitutes a core theoretical issue for organizational theory. The ecological theory of form emergence falls short of providing a full explanation because it treats legitimation as a primitive (unexplained) concept. Here, we use Hannan, Pólos, and Carroll's (2007) revised theory of organizational evolution to interpret and respecify the legitimation part of the density dependence model. Among other advantages, the respecification allows us to incorporate the insights of the “cultural-frame” institutional perspective. We study early Dutch accounting, an industry setting where form legitimation was fiercely contested by several professional associations in the period 1884–1939. We develop an analytical narrative about the historical legitimation process, and we also present systematic tests of the theory examining predictions about “fuzzy” density and population contrast. Estimated models of firm exit support the revised theory and reveal that fuzziness, induced from fragmented collective action, hampers it.

Abstract

Purpose

The purpose of this paper is to explore the emergence of sustainability governance through the unfolding hybridisation process between corporate governance and corporate social responsibility and the implications of this for understanding patterns in sustainability reporting over time.

Design/methodology/approach

The Gulf of Mexico oil spill incident is an extreme case study undertaken to examine its implications on the organisational legitimacy of British Petroleum (BP) and the latter’s response to the incident and beyond. The paper draws on Suchman’s legitimacy framework (1995) to understand sustainability governance as an organisational practice that evolved post the Gulf of Mexico oil spill to manage BP’s legitimacy. It draws on archival records and documentation from 2008 to 2017, as key sources for data collection, using interrogation by NVivo software.

Findings

Sustainability governance is a sound practice that was socially constructed to manage the re-legitimatisation process following the Gulf of Mexico oil spill. It is characterised by broadness (the interplay between the corporate governance and corporate social responsibility disciplines), dynamic (developing the tactics to repair and maintain legitimacy), agility (conforming to the accountability for socially responsible investment and ensuring steps towards geopolitically responsible investment) and interdependence (reflecting composition and interactions).

Practical implications

This paper has practical implications for organisations, in terms of sustainability governance’s constitution, mechanism and characteristics.

Social implications

This paper has implications not only for organisations, in terms of sustainability governance’s characteristics, but also for policy-makers, regulators and accounting education. However, the present paper’s insights are achieved through an in-depth and longitudinal case study.

Originality/value

This paper has problematized the concept of sustainability governance and elaborated its evolution (the emergence, enactment, deployment and interplay) process. The sustainability governance showed an otherwise organisational response that moves our understanding of the deployment of disclosure for complex organisational change as a way to discredit events.

The purpose of this paper is to provide an economic analysis of the sources of supply to the US shrimp market.

Abstract

Purpose

The purpose of this paper is to provide an economic analysis of the sources of supply to the US shrimp market.

Design/methodology/approach

The paper uses monthly time series data to estimate a simultaneous equations model with equations for domestic supplies from the Gulf of Mexico, imports, and prices.

Findings

Estimated long-run elasticities suggest that the domestic shrimp supply appears to be explained by seasons, diesel fuel price, hurricane activity, and shrimp price. The authors find evidence of a downward-slopping supply curve for the domestic harvesters that is likely to be temporary. Furthermore, anti-dumping duties have been ineffectual in curtailing imports produced by exploitation of natural shrimp biomass in developing countries and by technological advancements in aquaculture production. The authors also find evidence of a low exchange rate pass through. Finally, while domestic and import prices are not cointegrated, there is a two-way causality between them.

Practical implications

The authors found evidence that shrimp prices have fallen as import supply, due to technological advances in aquaculture, has risen faster than the US domestic demand over time suggesting a downward sloping supply curve. Also, the falling value of the US dollar has discouraged the imports, while the anti-dumping duties appear to have had little influence on the aggregate level of imports.

Originality/value

It provides a thorough investigation of the supply side of an important component of the US seafood market displaying the complexity of domestic producers’ reaction to falling prices, and ineffectual protectionism.
