Abstract

Purpose

Understanding the factors that contribute to the growth of sediment delta lobes in river systems has significant benefit towards protecting civil and social infrastructure from severe weather events. To develop this understanding, this paper aims to construct a three‐dimensional numerical model of a sediment delta depositing on to a two‐dimensional bedrock basement entering an ocean at a constant sea‐level.

Design/methodology/approach

The approach used adapts and applies techniques and schemes previously used in building numerical heat transfer models of melting systems. Particular emphasis is placed on modifying fixed grid enthalpy like schemes.

Findings

The resulting model provides important insight on the features that control the partition of sediment delta deposition between the land and ocean domains. The model also illustrates how tectonic subsidence may control the rate of delta growth.

Originality/value

This is the first numerical heat transfer inspired model of a three‐dimensional sediment delta deposit over both land and ocean domains. The problem has scientific merit in that it represents a melting‐like moving boundary problem with two distinct moving boundaries and a space/time dependent latent heat. Further, this work is a necessary first step towards building a comprehensive understanding of how to restore delta systems to protect civil and social infrastructure.

Abstract

Purpose

This masterclass examines the blue ocean value innovation process, how it works in practice and how it has evolved since the publication of Blue Ocean Strategy (2005) by W. Chan Kim and Renee Mauborgne as explored in their new book their new book Blue Ocean Shift (2017).

Design/methodology/approach

The main focus is the value innovation methodology that underlies blue ocean strategy.

Findings

Blue ocean strategy is a process of value innovation that uncovers new aggregations of demand by redefining the offering category.

Practical implications

Blue ocean strategy tends to focus on value innovation that uncovers new aggregations of demand by redefining the category while disruptive innovation tends to concentrate on new demand-creation that expands the current served market.

Originality/value

Blue ocean strategy sets out to reconfigure value propositions in compelling new ways that can deliver a quantum leap beyond the current red ocean value-cost frontier through raising buyer value and lowering company costs simultaneously. The emphasis on both value and innovation is essential to the creation of new “blue ocean” market spaces.

Abstract

Purpose

This study aims to examine the textual performance of the Ocean Ranger Disaster inquiry, thus responding to recent calls to “practice context” in historical writing. This study goes beyond the epistemological assumptions about the grounds for knowing about the past as the authors explore how history is produced in the context of power relations.

Design/methodology/approach

This paper imagines history-making as a storytelling performance. The authors combine critical historiography and critical sensemaking because these qualitative perspectives help us to understand the composition of the Ocean Ranger Royal Commission Report.

Findings

This case study makes a contribution within the genre of disaster inquiry reporting. The study explains how a formal historical record (the public inquiry report) may be created and how the report is related to aspects of power embedded in a writer’s sense of reality.

Social implications

The Ocean Ranger Disaster continues to be of tremendous importance to the people of Newfoundland, Canada. There have been numerous studies of the disaster, but these have been overwhelmingly focused on technical matters. To authors’ knowledge, this study is the first to consider the inquiry from an historical context perspective.

Originality/value

The study site enables reflection on a question not often asked in the management history literature: How can we critically understand the composition of an official disaster inquiry report in the context of its power relations?

Abstract

Purpose

This study strives to improve one’s understanding of tailored messaging as an organizational communication strategy that amplifies processes of organizational change at an individual level of personality traits.

Design/methodology/approach

A scientific experiment was conducted to test the effects of tailored messages on self-reported employee engagement during an organizational change process.

Findings

The results show that tailored messaging improves employee engagement for change when messages fit the specific needs of different personality types. Conversely, message tailoring can lower employee engagement when messages do not match personality types. Further, message tailoring has different impacts at different stages of a change project.

Research limitations/implications

An employee's ability to change as a function of his professional skill set as well as the project type (e.g. digital transformation project, post-merger integration project, leadership change project) should not be neglected in an overall model that aims to explain the success factors of change management.

Practical implications

Obviously, proper targeting, timing, as well as the implementation of a valid, legal and feasible method for identifying an employee's personality as well as other individual characteristics are equally important and challenging to improve change management outcomes.

Originality/value

This study adds value to the discussion on the efficacy of message tailoring as a communication strategy for organizational change.

Abstract

Purpose

The purpose of this paper is to review some applications of supercomputers, with the observation that a readily available PlayStation can rival supercomputers of a decade ago. Applications to ocean modelling and to examination of possibilities for quantum computing are discussed. Also discussed are the meaning of the term Wiki, and uses of Wikis in language learning.

Design/methodology/approach

The aim is to review developments on the internet, especially those of general cybernetic interest.

Findings

Supercomputers have valuable applications in biological modelling, medical record keeping and climatic studies and there is particular interest in their use to explore possibilities of quantum computing which may be the key to more powerful machines of the future. The value of Wikis is not confined to the Wikipedia.

Practical implications

PlayStations are likely to be taken seriously as programmable computers in certain areas. Possibilities for a new generation of quantum computers are discussed, as is also the use of Wikis in language learning.

Originality/value

It is hoped this is a valuable periodic review.

Abstract

Purpose

The purpose of this work is to present a procedure for determining the wind drift factor through two-dimensional computational fluid dynamics (CFD) simulations of the wind acting on a wavy sea surface, such that the subjectivity of its estimation is reduced.

Design/methodology/approach

The wind drift factor was determined by two-dimensional CFD analyses with open-channel condition. The characteristic wave was determined by the Sverdrup–Munk–Bretschneider (SMB) method. The uncertainty analysis is based on convergence studies using a single parameter refinement (grid and time step).

Findings

This procedure allows the estimation of the wind drift factor in a fetch-limited domain. The domain's value in the analyzed region is 0.0519 ± 4.92% which is consistent with the upper values of the wind drift factors reported in the literature.

Research limitations/implications

The use of a three-dimensional domain was impractical with the available computational resources because of the fine mesh required for wave modeling. The uncertainty analysis consisted only of a verification procedure. Validation against real data was not possible because of the lack of measured data in the analyzed region.

Originality/value

The wind drift factor is usually estimated based on either experience or random sampling. The original contribution of this work is the presentation of a CFD procedure for estimating the wind drift factor, in which the domain inlet is subjected to a wave boundary condition and to a wind velocity.

Abstract

Purpose

Quantitative and spatial-explicit flood risk information is of great importance for strengthening climate change adaptation and flood resilience. Shanghai is a coastal megacity at large estuary delta with rising flood risks. This study aims to quantify the overall economic-societal risks of storm flooding and their spatial patterns in Shanghai.

Design/methodology/approach

Based on multiple storm flood scenarios at different return periods, as well as fine-scale data sets including gridded GDP, gridded population and vector land-use, a probabilistic risk model incorporating geographic information system is used to assess the economic-societal risks of flooding and their spatial distributions.

Findings

Our results show that, from 1/200 to 1/5,000-year floods, the exposed assets will increase from USD 85.4bn to USD 657.6bn, and the direct economic losses will increase from USD 3.06bn to USD 52bn. The expected annual damage (EAD) of assets is around USD 84.36m. Hotpots of EAD are mainly distributed in the city center, the depressions along the upper Huangpu River in the southwest, the north coast of Hangzhou Bay, and the confluence of the Huangpu River and Yangtze River in the northeast. From 1/200 to 1/5,000-year floods, the exposed population will rise from 280 thousand to 2,420 thousand, and the estimated casualties will rise from 299 to 1,045. The expected annual casualties (EAC) are around 2.28. Hotspots of casualties are generally consistent with those of EAD.

Originality/value

In contrast to previous studies that focus on a single flood scenario or a particular type of flood exposure/risk in Shanghai, the findings contribute to an understanding of overall flood risks and their spatial patterns, which have significant implications for cost-benefit analysis of flood resilience strategies.

Abstract

International tourists traveling the eastern Adriatic are sometimes perplexed when some guides describe a Venetian bell tower, a Byzantine church, or Roman ruins as solely Croatian or Slovenian cultural heritage. If the same guides would then reveal that Marco Polo should be spelled Marko Polo for his Croatian origins, their perplexities would probably grow stronger. Most of the time, the same tourists are unaware that the Austrian Navy kept the codes and the tradition of the Serenissima Republic of Venice. Actually, until the Empire split in 1867, it was named Österreich-Venizianische Marine (Austro-Venetian Navy). Interestingly, according to the legend, the Austrian Admiral von Tegheltoff (German speaking subject of the Empire, born in the Alpine town of Maribor-Marburg, currently in Slovenia) after the famous victory in the battle of Lissa in 1866 hailed “Viva San Marco!” The Austrian victory against the fleet of the Kingdom of Italy was surprising and it has become a legendary one both in a good and bad sense. Accordingly, it has been later romanticized in different ways and strategically imbued with moral values by diverse actors. For instance, the journal of Admiral Wilhelm von Tegheltoff reports the famous sentence: “Iron men with wooden ships defeated wooden men with iron ships.” So, Tegheltoff stressed the virtues of the imperial subjects vis-à-vis the lack of moral strength of the opponents. As a matter of fact, the kingdom of Italy's fleet was stronger in numbers and technologically more advanced, but less organized and riddled with conflicts among the admirals. Quite differently, hundred years later, one of the most prominent journalists and writers from the Italian region of Veneto, Guido Piovene, said that: “the battle of Lissa has been the last great victory of the Venetian fleet.” The reason for such statement is that the mariners boarded in the Austro-Venetian fleet were all from former Venetian lands, such as Veneto, Istria and Dalmatia. Therefore, from this standpoint, the battle of Lissa is a matter of an “Italian” dispute between different maritime traditions, namely the Adriatic one of Venice and the antagonist Genoese or Neapolitan. Conversely, in Croatia and Slovenia, there is usually a different version of the story. The battle of Lissa is seen as a victory of a Croatian-Slavic navy over the Italians. Particularly, the battle of Vis (Lissa) is usually referred to as part of Croatian national history and it is a crucial step to legitimize the Croatian identity on the Adriatic Sea, because many of the sailors were ethnically Croats.

Abstract

Purpose

The purpose of this paper is to understand the role of entrepreneurial intention in promoting women entrepreneurship in Indian micro, small and medium enterprises (MSMEs). This study seeks to clarify the construct of entrepreneurial intention and then reports the validation of the entrepreneurial intention instrument.

Design/methodology/approach

An instrument has been designed and administered on a sample of 103 respondents across India from women entrepreneurs to understand the entrepreneurial intention by using cluster and snowball sampling. The data has been streamlined and then analyzed using descriptive analysis for validity and reliability checks.

Findings

This research was aimed to determine the constructs of entrepreneurial intention. Through data analysis, it has been observed that the reliability coefficients reveal the adequacy of the sample. The Cronbach’s alpha values for all the items in the instrument were found to be greater than or equal to 0.6. Strong correlations were also found between direct and indirect measures of entrepreneurial intention and hence confirmed that all the measures in the instrument were well constructed. Analysis has also explained the relationship between various constructs of entrepreneurial intention by using Pearson’s correlation coefficients. Strong and positive values of correlation explain the existence of the convergent and discriminant validity of the instrument.

Research limitations/implications

The research results obtained from the analysis of reliability and validity tests not only provides the establishment of the relationship among the various constructs but also suggests that the model provides a promising potential to measure entrepreneurial intention. This study will contribute to new knowledge of the conditions of women entrepreneurship from different perspectives by developing and validating an analytic model for promoting the women entrepreneurship in MSMEs of India.

Practical implications

From a government perspective, this model will help in designing training programmes for promoting women entrepreneurship in India. The obtained result also brings significant implications for practice as well as raises a broad future direction for other researchers

Originality/value

Extended SCCT model has recently suggested an inclusive framework of factors affecting the entrepreneurial intention, there is not much attempt made in research using this theory as background for predicting intention in the context of women entrepreneurship. This paper attempts to fill this gap by formulating a conceptual model for measuring entrepreneurial intention among women entrepreneurs by integrating and adapting the constructs of extended social cognitive career theory model and entrepreneurial potential model.
