Abstract

Purpose

This research aims to discuss the success of digital transformation focusing on the role of IT and management commitment in digitalization together with sectorial relevance as influencing factors. According to the literature, these dimensions are key elements of digitalization, and there is no consensus on their decisiveness. The authors measure the success of digital transformation with the digital innovation. The research is part of ongoing work, in which the IT-related practice of Hungarian organizations has been explored on an annual basis since 2009.

Design/methodology/approach

The research methodology is a combined one; both qualitative and quantitative methods were applied including surveying digital transformation literature, interviews with key representatives of Hungarian organizations, developing a survey to collect quantitative data, data collection and processing with PLS-SEM.

Findings

The results revealed that the digital innovations are strongly determined by business, management commitment and, to a far lesser extent, by strategy. In the case of digital transformation, the role of IT departments and the services they provide are less relevant.

Research limitations/implications

The most important limitation of the research is the size and composition of the sample. Results do not present the situation of a specific industrial sector.

Originality/value

Digital technologies influence and disrupt practically every industry; the development of information and communication technology has changed economies all over the world. Decisive factors of digital transformations are widely researched, but there is no consensus about them. This research contributes to understanding the role of IT department and their services in this process together with leadership, sectorial relevance as influencing factors.

This study aims to investigate how measuring the lean practices–performance relationship could add value to businesses.

Abstract

Purpose

This study aims to investigate how measuring the lean practices–performance relationship could add value to businesses.

Design/methodology/approach

Case-study methodology was used for the quantitative analysis of self-assessed lean capability scores and key manufacturing performance indicators from a global consumer goods company. Up to 80 sites over 3 years were analysed. Partial least squares structural equation modelling (PLS-SEM) is used to analyse the lean implementation–performance relationship.

Findings

Results show that different performance areas may be affected differently and suggest that the measured relationship may depend on the reliability of the self-assessment.

Research limitations/implications

The research is based on the manufacturing sites of a single company, implementing the same lean methodology, producing similar products and using similar process technologies. This helps to control confounding variables but may limit the generalisability of the findings.

Practical implications

Practitioners can use the measurement method to improve lean-based performance-improvement projects. The study suggests that the PLS-SEM technique could improve the calibration of lean-practice self-assessment and could identify further areas for improvement.

Originality/value

Very few papers developed measurement methods for the effectiveness of lean-practice implementation using objective manufacturing performance data within a single multinational company.

Abstract

Purpose

The purpose of this paper is to analyse the influence of various firing profiles on microstructural and dielectric properties of low-temperature, co-fired ceramic (LTCC) substrates in a GHz frequency range. According these analyses, sintering process can be controlled and modified to achieve better performance of devices fabricated from LTCC substrates.

Design/methodology/approach

Samples from LTCC substrates GreenTape 951 and GreenTape 9K7 were sintered by four firing profiles. Basic firing profile recommended by the manufacturer was modified by increasing the peak temperature or the dwell time at the peak temperature. The influence of firing profile on microstructural properties was analysed according to measurements by X-ray diffractometer (application of the Cu K-alpha radiation and the Bragg-Brentano method), and the influence on dielectric properties (dielectric constant and dielectric losses) was analysed according to measurements by split cylinder resonator method at 9.7 and 12.5 GHz.

Findings

Rising of the peak temperature or extension of dwell time at this temperature has influence on all analysed properties of LTCC substrates. Size of crystallites can be changed by modification of firing profile as well as microdeformation. In addition, dielectric properties can be changed too by modification of the firing profile. Correlation between microdeformation and dielectric losses was observed.

Originality/value

The novelty of this work lies in finding the mutual relationship between changes in microstructural (size of grains and microdeformation) and dielectric properties (dielectric constant and dielectric losses) caused by different firing profiles.

Abstract

Purpose

The purpose of this paper is to generalize the traditional risk evaluation methods and to specify a multi-level risk evaluation framework, in order to prepare customized risk evaluation and to enable effectively integrating the elements of risk evaluation.

Design/methodology/approach

A real case study of an electric motor manufacturing company is presented to illustrate the advantages of this new framework compared to the traditional and fuzzy failure mode and effect analysis (FMEA) approaches.

Findings

The essence of the proposed total risk evaluation framework (TREF) is its flexible approach that enables the effective integration of firms’ individual requirements by developing tailor-made organizational risk evaluation.

Originality/value

Increasing product/service complexity has led to increasingly complex yet unique organizational operations; as a result, their risk evaluation is a very challenging task. Distinct structures, characteristics and processes within and between organizations require a flexible yet robust approach of evaluating risks efficiently. Most recent risk evaluation approaches are considered to be inadequate due to the lack of flexibility and an inappropriate structure for addressing the unique organizational demands and contextual factors. To address this challenge effectively, taking a crucial step toward customization of risk evaluation.

Abstract

Purpose

Security is one of the most important challenges for contemporary integrated urban developments. In Hungary, every strategic document highlights this goal, seeking social and smart city solutions to the problem. Yet, what about crime prevention through environmental design (CPTED)? The purpose of the paper is to introduce a Central-European perspective into the international discussion of the topic.

Design/methodology/approach

Focusing on European Union-funded renewal of public space in the historic city centre of Budapest, the research investigates how urban security can be facilitated through urban planning and design. The analysis of two projects based on design documents and interviews with actors highlights the importance of CPTED, although it is not recognised officially either in the development or in the management phase.

Findings

March 15th Square is an attractive contemporary public space in the tourist-historic city centre. The project was centrally planned, executed with typical EU indicators, but without any special requirements for security. The process resulted in a safescape. By contrast, the main principal for the renewal of Teleki László Square, the first Hungarian example of community-based planning, was to instil a feeling of security. The public square became a fenced defensible space.

Practical implications

The analysis method can be used for other projects evaluating changes in urban security due to public space renewal: history, requirements for security, design solutions for space division, materials and urban furniture, as well as use of space and management after the regeneration.

Originality/value

The paper uncovers Hungarian cases where environmental crime prevention criteria are not explicitly but implicitly present in contemporary urban planning and design. In relation to urban security, it highlights the gap that exists among disciplines, indicative of a lack of dialogue among policymakers, researchers, designers and management.

Abstract

Purpose – This chapter aims to show how media law strongly contributed to shape in Hungary what has been pictured as a U-turn. This illiberal trend was subsequently strengthened during the Covid-19 pandemic. Methodology/Approach – It considers that law also constitutes and not only orders political and social relationships. Law, including media law, has been in Hungary one of the main factors of change or rather of political-social construction. This chapter therefore moves from the study of positive law and analyzes Hungarian media laws within the theoretical framework of illiberal democracy, drawing from contributions to political science and socio-legal studies. Findings – This chapter demonstrated that media laws have outlined in Hungary a centralized regulatory system with broad powers, which lacks political independence, therefore encouraging self-censorship and limiting freedom of expression and pluralism. These laws contributed to shape the illiberal U-turn occurred in the country before the pandemic, but the coronavirus offered the occasion to reinforce government powers, giving the leeway to rule with no or minimum scrutiny for an indefinite period and further limiting dissent. The analysis enabled to argue that neither the media regulation established during the past decade nor the laws adopted during the Covid-19 pandemic are compatible with a modern democracy. Originality/Value – Based on existing literature, little research has been conducted on the appearance and endurance of non-democratic regimes, and supposedly even less within the context of the coronavirus pandemic which started only a few months ago, compared to the contributions available on democratization processes and democratic consolidation.

Abstract

Purpose

The purpose of this paper is to create multilayer substrate (composite) from various low temperature co-fired ceramic (LTCC) substrates by their mutual combinations and to analyse influence of these multilayer substrates on dielectric properties in GHz frequency range.

Design/methodology/approach

GreenTape 951, GreenTape 9K7 and Murata LFC were used to create compound multilayer substrates that include three layers: middle layer is from Murata LFC, and both upper and bottom layers are either from GreenTape 951 or GreenTape 9K7. Shrinkage in all x-, y- and z-axes of all substrates including multilayer substrates were analysed, and influence of different shrinkage on dielectric properties was examined by microstrip ring resonators applied on all mentioned of substrates.

Findings

The middle layer of Murata LFC has significant influence on shrinkage value of composites which has a good repeatability and minimalizes problems with design of multilayer LTCC devices. Impact of middle layer from Murata LFC on dielectric constant is not significant, but on the other hand Q factor (loss tangent) of these composites is increased according to inhomogeneity between single LTCC layers, especially at frequency around 6 GHz.

Originality/value

The novelty of this work lies in creating multilayers systems from different types of LTCC substrates to find combination with the most suitable physical and dielectric properties for various purposes in GHz range applications.

Abstract

Purpose

The purpose of this paper is to get a detailed picture of digital library education in Hungary taken in comparison with international experiences.

Design/methodology/approach

Digital library education (DLE) is examined through the example of three Hungarian schools of Library and Information Science (LIS). After defining the virtual library, the digital library (DL), the hybrid library and the electronic library, notions vital for DLE, the results of international surveys are compared to Hungarian curricula.

Findings

The described curricula follow international patterns outlined in the literature. The content of education is up to date and is adjusted to the quickly developing world of digital libraries.

Research limitations/implications

Experiences come form a higher education system that is in a stage of transition. Lessons learnt however can be useful for the development of curricula taking DL issues into consideration.

Practical implications

Similar examinations of curricula, supplemented by national and European surveys could highly contribute to the success of DLE programmes.

Originality/value

The paper provides additional data and viewpoints on DLE.
