Attributes conveying cultural significance play a key role in heritage management, as well as in differentiating interventions in built heritage. However, seldom the relation between interventions and attributes, either tangible or intangible, has been researched systematically. How do both tangible and intangible attributes and interventions relate? What attributes make interventions on built heritage differ?

This paper conducts a systematic content analysis of forty-one international doctrinal documents—mainly adopted by the Council of Europe, UNESCO and ICOMOS, between 1877 and 2021. The main aim is to reveal and compare the selected eight intervention concepts, namely—restoration (C1), preservation (C2), conservation (C3), adaptation (C4), rehabilitation (C5), relocation (C6), reconstruction (C7) and renewal (C8)—and their definitions, in relation to attributes, both tangible and intangible. The intensity of the relationship between intervention concepts and attributes is determined based on the frequency of the mentioned attributes per intervention.

There were three key findings. First, although the attention to intangible attributes has increased in the last decades, the relationship between interventions and tangible attributes remains stronger. The highest frequency of referencing the tangible attributes was identified in “relocation” and “preservation,” while the lowest was in “rehabilitation.” Second, certain attributes play contradictory roles, e.g. “material,” “use” and “process,” which creates inconsistent definitions between documents. Third, as attributes often include one another in building layers, they trigger the intervention concepts in hierarchical patterns.

This paper explores and discusses the results of a novel comparative analysis between different intervention concepts and definitions, with a particular focus on the attributes. The results can support further research and practice, clarifying the identified differences and similarities.

Much remains unknown about how young children orient to computational objects and how we as learning scientists can orient to young children as computational thinkers. While some research exists on how children learn programming, very little has been written about how they learn the technical skills needed to operate technologies or to fix breakdowns that occur in the code or the machine. The purpose of this study is to explore how children perform technical knowledge in tangible programming environments.

The current study examines the organization of young children’s technical knowledge in the context of a design-based study of Kindergarteners learning to code using robot coding toys, where groups of children collaboratively debugged programs. The authors conducted iterative rounds of qualitative coding of video recordings in kindergarten classrooms and interaction analysis of children using coding robots.

The authors found that as children repaired bugs at the level of the program and at the level of the physical apparatus, they were performing essential technical knowledge; the authors focus on how demonstrating technical knowledge was organized pedagogically and collectively achieved.

Drawing broadly from studies of the social organization of technical work in professional settings, we argue that technical knowledge is easy to overlook but essential for learning to repair programs. The authors suggest how tangible programming environments represent pedagogically important contexts for dis-embedding young children’s essential technical knowledge from the more abstract knowledge of programming.

The aim of this paper is to explore, analyse and summarise the potential tangible user interface (TUI) design features for dyslexics learning to read and spell.

This study adopts a systematic literature review method through a manual search of published papers from 2011. This systematic literature review consists of three main phases starting with planning the review, conducting the review and studying the selection and reporting the results.

As the result, 10 papers were found that are considered most applicable as they met the review criteria. Based on the 10 papers, 11 design features are found in the current TUIs design features implemented in the tangible system dedicated for dyslexia and reading. The 11 design features are viewed to be fundamental and useful for the groundwork towards designing and developing a comprehensive TUIs design specifically and exclusively meant for dyslexic children learning to read and spell.

A critical reading of past literature relating to the TUIs concept reveals that this concept still appears to be under-explored even though it was introduced two decades ago. This systematic literature review highlights directions for future research, involving the dyslexic children early in the design process towards the evaluation of the prototype and finally examining the outcome of TUIs on children's learning.

Are there cases or contexts where certain groups of customers who are expected to place a considerable emphasis and importance on the tangible qualities of services end up attributing a greater weight to the intangible qualities? This paper attempts to exemplify the existence of such cases, and explain why such cases are, at times, paradoxical in nature, and how such cases could arise.

The paper employs a structural‐equation‐modeling approach to theorize about, and empirically examine, the tangible and intangible determinants of service quality. The model and the path developed in the paper also capture the relationship between service quality and customer satisfaction. Using AMOS, the empirical estimation of the model is carried out.

The central finding is that all intangible factors associated with service quality turn out to be unequivocally more important than the tangible ones in the Turkish non‐profit health‐care sector under investigation. In other words, intangible factors appear to play a statistically more significant role compared with tangible factors in determining the overall customer satisfaction and the quality of non‐profit health‐care services. Considering that, in developing countries, tangible factors are expected to be among the most scarce, and hence, most valuable ones, the relative unimportance of tangible factors constitutes a paradox to be explained and resolved.

This paper contributes to the literature by bringing to light a striking phenomenon which is largely unnoticed in the literature, namely that, in certain cases, there might exist a fundamental asymmetry and difference between the influences of tangible and intangible factors on service quality, and that difference in certain contexts, as in the case of the Turkish health‐care sector, constitutes a paradox to be explained. The paper demonstrates the possibility of such paradoxical cases and provides cultural and sector‐specific explanations for this seemingly puzzling phenomenon in question.

While the investment in construction projects has increased over the past few decades, low construction project productivity (CPP) appeared to be persistent, thereby reflecting an “investment-in-failure” paradox between the investment and CPP. Hence, this paper aims to develop a systematic and holistic CPP evaluation framework to explain the apparent paradox in the construction industry.

The paper first reviews the literature about the theories of system, production, principal–agent and project success evaluation to re-conceptualise the CPP and proposes a two-stage CPP evaluation framework. The framework is subsequently explored through a sequential qualitative mixed-methods design within the context of the Hong Kong construction industry by combining 32 semi-structured interviews with senior industry experts and exploratory case studies, with three real-life construction projects.

The paper identifies three system boundaries for CPP evaluation, that is, parameter, timeframe and stakeholder, and develops a two-stage CPP evaluation framework to indicate site efficiency and utilisation effectiveness, thereby accessing the productivity of both the construction and post-construction stages. The “investment-in-failure” paradox associated with current CPP evaluation approaches is primarily attributed to the narrowly defined CPP boundaries.

The qualitative exploration of the evaluation framework only focusses on the Hong Kong construction industry. Further case studies within other urban contexts could be used to improve the generalisability of the findings. Quantitative research is also necessary to advance theoretical development of the two-stage CPP evaluation.

The systemic CPP conceptualisation and the two-stage CPP evaluation framework support the systems thinking of industry stakeholders and enable them to formulate holistic strategies for long-term CPP enhancement.

The research demonstrates the needs to expand the system boundaries of CPP to reflect its systemic value and to shift the paradigm of CPP evaluation from being output-orientated and quantity-focussed to being outcome-orientated and value-focussed.

The purpose of this paper is to create a benchmark and identify best practices for Project Portfolio Management (PPM) for both tangible product‐based and service product‐based development project portfolios.

A questionnaire was developed to gather data to compare the PPM methods used, PPM performance, PPM challenges, and resulting new product success measures in 60 Australian organisations in a diverse range of service and manufacturing industries.

The paper finds that PPM practices are shown to be very similar for service product development project portfolios and tangible product development project portfolios. New product success rates show strong correlation with measures of PPM performance and the use of some PPM methods is correlated with specific PPM performance outcomes.

The findings in this paper are based on a survey of a diverse sample of 60 Australian organisations. The results are strengthened by comparisons with similar North American research; however, they may not be representative of all environments. Research in other regions would further qualify the findings. As each organisation's PPM process is unique, case study methods are recommended for future studies to capture more of the complexity in the environment.

The paper shows that PPM practitioners and executives who make decisions about the development of tangible products and/or service products will benefit from the findings.

This paper extends the existing understanding of PPM practices to include service development project portfolios as well as tangible product development project portfolios and strengthens the links between PPM practices and outcomes.

The purpose of this paper is to report on the development of a collaborative Heritage Building Information Modelling (HBIM) of a 19th-century multi-building industrial site in the UK. The buildings were Grade II listed by Historic England for architectural and structural features. The buildings were also a key element of the industrial heritage and folklore of the surrounding area. As the site was due to undergo major renovation work, this project was initiated to develop a HBIM of the site that encapsulated both tangible and intangible heritage data.

The design of the research in this study combined multiple research methods. Building on an analysis of secondary data surrounding HBIM, a community of practice was established to shape the development of an HBIM execution plan (HBEP) and underpin the collaborative BIM development. The tangible HBIM geometry was predominantly developed using a scan to BIM methodology, whereas intangible heritage data were undertaken using unstructured interviews and a focus group used to inform the presentation approach of the HBIM data.

The project produced a collaboratively generated multi-building HBIM. The study identified the need for a dedicated HBEP that varies from prevailing BIM execution plans on construction projects. Tangible geometry of the buildings was modelled to LOD3 of the Historic England guidelines. Notably, the work identified the fluid nature of intangible data and the need to include this in an HBIM to fully support design, construction and operation of the building after renovation. A methodology was implemented to categorise intangible heritage data within a BIM context and an approach to interrogate these data from within existing BIM software tools.

The paper has presented an approach to the development of HBIM for large sites containing multiple buildings/assets. The framework implemented for an HBEP can be reproduced by future researchers and practitioners wishing to undertake similar projects. The method for identifying and categorising intangible heritage information through the developed level of intangible cultural heritage was presented as new knowledge. The development of HBIM to bring together tangible and intangible data has the potential to provide a model for future work in the field and augment existing BIM data sets used during the asset lifecycle.

This paper aims to investigate if the world top manufacturing corporations' cost structures are moving from tangible to intangible activities and their impact on profitability.

The theoretical approach is interdisciplinary, combining global value chains, international manufacturing networks, cost management literatures. The empirical approach has a sample out of financial statements' data from 220 multinational corporations between 2006 and 2017, grouping them by technological intensity. It is created the “COGS-share” indicator – the ratio between the costs of goods sold and overall costs and expenses – as a proxy for the firms' expenses of tangible and intangible value chain activities. It is tested as an explanatory variable for the companies' profits through dynamic panel data econometric models.

The results show that the cost structure still is very concentrated in tangibles. Though costs of both tangible and intangible activities negatively impact profits, they affect value generation differently: the higher the share of intangible in comparison to tangible activities in overall cost and expenses, the greater the profits in most manufacturing groups, regardless of their technological intensity.

The empirical analysis simplifies the composition of value chains per activity because financial statements data are aggregates, preventing detailed analysis by markets, business units or products. Stocks' levels are assumed to be at the desired level during the time series. The dataset does not allow value curves to be drawn because direct wages' data and more precise information on cost (especially deferred assets and wages) are missing.

The presented approach, particularly the COGS-share indicator, contribute to assess value generation from activities for improving corporate strategies and public policies on operations and cost management of global value chains.

Supporting upgrading decisions that impact value production, allocation and distribution between workers, firms and countries.

Interdisciplinary theoretical and empirical assessment of the manufacturing companies' cost structures and profits based on financial statements data for the better understanding of value generation from tangible and intangible activities.

The purpose of this paper is to bring together the fields of participatory design, design for all, accessible music, tangible interaction and musicking to propose musicking for all, where participants can take part on their own terms, with their own intentions, initiatives and interpretations. The goal is to promote well‐being and health among the participants.

Co‐creative tangibles to enable musicking for all have been created and evaluated in a research project. The paper uses the experiences so far in this project to propose “musicking for all”, based on the fields mentioned in “Purpose” above.

Participatory design, design for all and tangible interaction forms a promising basis for musicking for all. Challenges/paradoxes emerge when applying participatory design approaches to design work involving disabled children.

The paper contributes with an original view on musicking for disabled children, and proposes musicking for all based on the fields of research mentioned in “Purpose” above. The value in the contribution is a fresh view on co‐creative tangibles for disabled children, and a suggested way forward to improve health and well‐being for this user group.

In the last three years, the U.S. Equal Employment Opportunity Commission received 246,575 charges of workplace discrimination, of which 43,437 alleged sexual harassment. In 1998, the U.S. Supreme Court issued two landmark decisions governing how U.S. courts analyze sexual harassment cases. Since those cases, U.S. courts have been faced with a new conundrum: is a constructive discharge a “tangible employment action” that gives rise to automatic employer liability? Although the U.S. Circuit Courts of Appeals have split on the issue, the trend appears to be in favor of imposing automatic liability, effectively denying employers a defense in cases in which the alleged victim often failed to report harassing conduct. This article argues that classifying a “constructive discharge” as a “tangible employment action” will, in most circumstances, violate the Supreme Court’s admonition that “no award against a liable employer should reward a plaintiff for what her own efforts could have avoided”.
