Abstract

Purpose

The warp-knitted fully-formed shorts are one kind of fully-formed garments knitted by a double-needle bar machine, which is widely used in the medical field. Because of its distinctive forming method, designers are unable to grasp the final effect of the product accurately during the design process. The purpose of this paper is to clarify a visible 3D simulation method in the design process along with the knitting method and structure characteristics, which is reflected in the final product effect.

Design/methodology/approach

This study introduces a simulation process for warp-knitted fully-formed fabric from an input 3D surface model group. Stitch mesh models are established according to the garment structure and the triangle index of the garment model that swchape-controlling points belong to is calculated. The garment model group includes a 2D plate and a 3D model, between which there is a space coordinate transformation relationship. The study makes use of the 3D tubes to connect the coordinate points in order and render the tubes in real yarn colors. The effects of two parameters, radial segment and tubular segment, are analyzed and decided to obtain a fine surface within a reasonable rendering time.

Findings

A stereoscopic simulation process from flat fabric to 3D product is realized using computer graphics technology. The warp-knitted fully-formed short is shown during the design process within a short time by setting the rendering parameters of tubular segments (ts = 125) and radial segments (rs = 6).

Originality/value

Visual simulation for the shorts provides a time-saving and resource-saving method for structure design and parameter modification before knitting. There is no need to knit samples repeatedly to satisfy demand, which indicates that it is a saver of time and resources.

Abstract

Purpose

In an era overshadowed by the alarming consequences of climate change and the escalating peril of recurring floods for communities worldwide, the significance of proficient disaster risk management has reached unprecedented levels. The successful implementation of disaster risk management necessitates the ability to make informed decisions. To this end, the utilization of three-dimensional (3D) visualization and Web-based rendering offers decision-makers the opportunity to engage with interactive data representations. This study aims to focus on Thiruvananthapuram, India, where the analysis of flooding caused by the Karamana River aims to furnish valuable insights for facilitating well-informed decision-making in the realm of disaster management.

Design/methodology/approach

This work introduces a systematic procedure for evaluating the influence of flooding on 3D building models through the utilization of Web-based visualization and rendering techniques. To ensure precision, aerial light detection and ranging (LiDAR) data is used to generate accurate 3D building models in CityGML format, adhering to the standards set by the Open Geospatial Consortium. By using one-meter digital elevation models derived from LiDAR data, flood simulations are conducted to analyze flow patterns at different discharge levels. The integration of 3D building maps with geographic information system (GIS)-based vector maps and a flood risk map enables the assessment of the extent of inundation. To facilitate visualization and querying tasks, a Web-based graphical user interface (GUI) is developed.

Findings

The efficiency of comprehensive 3D building maps in evaluating flood consequences in Thiruvananthapuram has been established by the research. By merging with GIS-based vector maps and a flood risk map, it becomes possible to scrutinize the extent of inundation and the affected structures. Furthermore, the Web-based GUI facilitates interactive data exploration, visualization and querying, thereby assisting in decision-making.

Originality/value

The study introduces an innovative approach that merges LiDAR data, 3D building mapping, flood simulation and Web-based visualization, which can be advantageous for decision-makers in disaster risk management and may have practical use in various regions and urban areas.

Abstract

Purpose

This study explores how introducing a permissioned blockchain in a supply chain context impacts accountability relationships and the process of rendering an account. The authors explore how implementing a digital transformation impacts the governance of network transactions.

Design/methodology/approach

The authors mobilize 28 interviews and documentary analysis. The authors focus on early blockchain adopters to get an insight into how implementing a permissioned blockchain can transform information sharing, coordination and collaboration between business partners, now converted into network participants.

Findings

The authors suggest that implementing a permissioned blockchain impacts accountability across three levers, namely through the ledger, through the code and through the people, where these levers are interconnected. Blockchains are often valued for their ability to enable transparency through the visibility of transactions, but the authors argue that this is an incomplete view. Rather, transparency alone does not help to satisfy a duty of accountability, as it can result in selective disclosure or obfuscation.

Originality/value

The authors extend the conceptualizations of accountability in the blockchain literature by focusing on how accountability relationships are enacted, and accounts are rendered in a permissioned blockchain context. Additionally, the authors complement existing work on accountability and governance by suggesting an integrated model across three dimensions: ledger, code and people.

Abstract

Using data from a feminist discourse analysis of comments on Facebook news articles, this research outlines backlash and regulatory practices directed towards youth activists Greta Thunberg, X González and Malala Yousafzai. A conceptual framework of semiotic violence highlights how these comments function to silence, delegitimise, vilify and punish sociopolitically active girls who challenge the status quo. The first mode of semiotic violence works to symbolically annihilate girl activists by silencing or rendering their political contributions invisible. The most obvious manifestation of this is instructing girls to shut up and go away. Additionally, their activism is ignored by refusals to acknowledge it as appropriate through suggestions they focus on gender-normative activities, such as domestic chores, playing with dolls and finding boyfriends. Undermining girls’ agency by describing them as puppets, mouthpieces, script readers, pawns and tools is also common. Here, girls’ contributions are rendered invisible through implications that they are being brainwashed and manipulated. The second mode of semiotic violence reinforces ideologies that girls are not politically competent and punishes them for being outspoken. This includes explicitly discrediting girls’ knowledge and abilities. Regulating their emotionality is also prevalent. This is consistent with Liberal political theory which justified women’s exclusion from public life by associating men with reason and women with emotion. Finally, insults degrade them for transgressing into a space demarcated as an adult and masculine realm. The semiotic violence directed towards these ‘girl power’ figures highlights that many people do not believe girls have the right to assert their sociopolitical opinion.

Abstract

Purpose

This paper presents the outcomes of the international project “Protecting Landscape Heritage: a requalification project as an instrument for the re-birth of Quang Tri Old Citadel in Vietnam”, achieved with scientific cooperation between the Università Politecnica delle Marche (Italy) and Hue University of Sciences (Vietnam) funded by the Italian Ministry of Foreign Affairs and International Cooperation and Ministry of Science and Technology of Vietnam. The research focuses on the Quang Tri Citadel, founded in 1809 and now in an advanced state of degradation.

Design/methodology/approach

For the purpose of rehabilitation, the wide multidisciplinary project first examined the historical context of the military model, the architectural aspects of the structure, the characterization of the existing materials, the degradation levels of different parts, and, finally, a proposal of the suggested interventions.

Findings

The original structure and geometry were extrapolated and studied. Building materials were produced with nearby raw materials. Firing temperatures of bricks ranged from 800 to 1,000 °C, hydraulic lime was supposed the binder of the mortar with a calcination temperature lower than 1,000 °C. Damage assessment was provided and after these analyses a requalification project was proposed so the cultural heritage can play a role for the future in the dialog between different cultures.

Originality/value

The requalification project achieved by an integrated analytical approach defines aspects in relation to the restoration of the structures, enabling compliance with the geometry, techniques, building materials used in the original construction and allowing its guardianship and management to align with the historical context of the architectural heritage.

Abstract

Purpose

Scholarly communications, particularly, questions and answers (Q&A) present on digital scholarly platforms provide a new avenue to gain knowledge. However, several studies have raised a concern about the content anomalies in these Q&A and suggested a proper validation before utilizing them in scholarly applications such as influence analysis and content-based recommendation systems. The content anomalies are referred as disinformation in this research. The purpose of this research is firstly, to assess scholarly communications in order to identify disinformation and secondly, to help scholarly platforms determine the scholars who probably disseminate such disinformation. These scholars are referred as the probable sources of disinformation.

Design/methodology/approach

To identify disinformation, the proposed model deduces (1) content redundancy and contextual redundancy in questions (2) contextual nonrelevance in answers with respect to the questions and (3) quality of answers with respect to the expertise of the answering scholars. Then, the model determines the probable sources of disinformation using the statistical analysis.

Findings

The model is evaluated on ResearchGate (RG) data. Results suggest that the model efficiently identifies disinformation from scholarly communications and accurately detects the probable sources of disinformation.

Practical implications

Different platforms with communication portals can use this model as a regulatory mechanism to restrict the prorogation of disinformation. Scholarly platforms can use this model to generate an accurate influence assessment mechanism and also relevant recommendations for their scholars.

Originality/value

The existing studies majorly deal with validating the answers using statistical measures. The proposed model focuses on questions as well as answers and performs a contextual analysis using an advanced word embedding technique.

Abstract

Purpose

The COVID-19 pandemic has had a disruptive effect on the health system. Health facility leaders were at the forefront of maintaining service delivery and were exposed to varied stressors in the early phase of the pandemic. This study aims to explore the leadership experiences of health facility leaders during the early phase of the COVID-19 pandemic in Nigeria’s epicentre.

Design/methodology/approach

This study conducted an exploratory descriptive qualitative study. To achieve this, 33 health facility leaders of different cadres across primary, secondary, and tertiary levels of the public health care system in Lagos, Nigeria, were remotely interviewed. The key informant interviews were transcribed verbatim and were analysed by using thematic analysis.

Findings

The health facility leaders experienced heightened levels of fear, anxiety and stressors during the early phase of the pandemic. They also had genuine concerns about exposing their family members to the virus and had to manage some health-care workers who were afraid for their lives and reluctant. Coping mechanisms included psychological and social support, innovative hygiene measures at health facility and at home, training and staff welfare in more ways than usual. They were motivated to continue rendering services during the crisis because of their passion, their calling, the Hippocratic oath and support from the State government.

Originality/value

The experiences of health facility leaders from different parts of the world have been documented. However, to the best of the authors’ knowledge, this is one of the first studies that specifically report multi-layer leadership experiences of health facility leaders during the early phase of the COVID-19 pandemic in sub-Saharan Africa.

Abstract

This chapter locates our book in social science debates and critiques challenging ontological and epistemological assumptions underpinning researching approaches emanating from the global north. This is an important contextualising move, given that these debates have surfaced crucial understandings about the dangers of unquestioned assumptions underpinning researching approaches in intercultural and cross-cultural contexts. The chapter outlines how practice architectures, the key theoretical lens employed in this book, have attempted to counter these exclusions. It focusses on the theory’s emergence from the relational (political and material) work of the pedagogy, education, and praxis (PEP) network. This historicising move is part of our shared authorial commitment to rendering visible the taken-for-granted assumptions underpinning researching approaches, including those, such as practice architectures theory, that have a shared commitment to critical educational praxis. The final section of the chapter considers the possibilities and limitations of practice architectures theory as a means of challenging taken-for-granted ontological and epistemological assumptions of research and researching practices.

Abstract

Purpose

This research analyses challenges faced by users at various levels in planning and designing participatory simulation models of cities. It aims to identify issues that hinder experts from maximising the effectiveness of the SUMO tool. Additionally, evaluating current methods highlights their strengths and weaknesses, facilitating the use of participatory simulation advantages to address these issues. Finally, the presented case studies illustrate the diversity of user groups and emphasise the need for further development of blueprints.

Design/methodology/approach

In this research, action research was used to assess and improve a step-by-step guideline. The guideline's conceptual design is based on stakeholder analysis results from those involved in developing urban logistics scenarios and feedback from potential users. A two-round process of application and refinement was conducted to evaluate and enhance the guideline's initial version.

Findings

The guidelines still demand an advanced skill level in simulation modelling, rendering them less effective for the intended audience. However, they have proven beneficial in a simulation course for students, emphasising the importance of developing accurate conceptual models and the need for careful implementation.

Originality/value

This paper introduces a step-by-step guideline designed to tackle challenges in modelling urban logistics scenarios using SUMO simulation software. The guideline's effectiveness was tested and enhanced through experiments involving diverse groups of students, varying in their experience with simulation modelling. This approach demonstrates the guideline's applicability and adaptability across different skill levels.

Abstract

Purpose

The COVID19 crisis has thrown wide open the debate on Europe’s Economic and Monetary Union’s (EMU) future. Next Generation EU (NGEU) has broken the stalemate over a central fiscal capacity. The open question is whether NGEU is a one-off or a first step. The suspension of the Stability and Growth Pact has given new urgency to the debate on reforming EMU’s fiscal rules.

Design/methodology/approach

There is no debate as yet about how these two prospects relate to each other. This paper argues that a permanent fiscal capacity and revised rules should be seen as alternatives.

Findings

This study makes two claims: first, a fiscal capacity renders a reformed pact unnecessary and second, that is an optimal solution politically. A fiscal capacity would provide an efficient asymmetric shock absorber and therefore reduce the need for pre-emptive action against negative cross-border externalities. It would also provide an abundant supply of an EU-wide safe asset around which to structure the EU’s financial system, thus rendering unnecessary the backstopping of member states' debts.

Originality/value

This would restore democratic accountability while eliminating moral hazard and enforcement problems.
