In order to complement a large-scale long-term investigation of prestressing strand types for post-tensionsing of bridges, passive and active electrochemical tests were carried out on bare and grouted specimens exposed to salt water conditions as a function of time. The materials tested included seven-wire strands made of hot dip galvanized or zinc coated steel, stainless steel, stainless clad steel, copper clad steel, flow-filled epoxy coated steel and conventional steel as control. Based on corrosion potentials, polarization resistance tests, potentiodynamic tests, weight loss, and visual observations, epoxy coated strands, stainless and stainless clad strands were identified as possible alternatives to conventional steel that might help to minimize corrosion.

In multi-criteria ranking problems, the UTA-like methods can be used to infer the value functions that restore the decision-maker’s (DM’s) indirect preference information. These value functions represent all possible preference systems for the DM. In this paper, we aim to develop a method for determining the complete ranking of alternatives based on all such value functions.

We extend the DM’s inductive preference for value functions in the selection of a representative value function to rankings of alternatives and construct a novel measure referred as the representativeness index to evaluate the performance of rankings relative to the inductive preference. Subsequently, by exploring all value functions that are capable of generating a ranking, two robust representativeness indices are constructed and a simulation algorithm is proposed for calculating the robust representativeness index.

Determining the ranking based on the representative value function can be seen as selecting the ranking with the largest representativeness index. Additionally, we find through a case study that the ranking determined based on robust representativeness indices has good robustness in the sense of inductive preferences.

The inductive preference is a manifestation of the DM’s preference system. This paper proposes a method for measuring the performance of rankings relative to inductive preferences. The performance of a ranking is defined as the performance of all value functions that can produce that ranking relative to the inductive preference. In turn, it is possible to identify the ranking that best matches the DM’s preference system.

The purpose of this paper is to pursue the themes of feminine identity, doubling and (in)visibility; first in terms of “signifyin(g)” as a cultural and literary strategy, and second, in terms of quilting seen from the fiction of Alice Walker to the quilting of Gee's Bend. In the background, there plays the relationship between art and commodification.

The paper examines “commodification” and “doubling” in the case of the Gee's Bend quilt makers. The quilts foreshadow the modernist aesthetic and are of the highest aesthetic quality. They were made in a traditional rural society by very poor uneducated black women. The quilts were not made to be sold, but were dedicated to familial remembrance and to immediate aesthetic pleasure.

Commodification doubles self and work, life and object, uniqueness and standardization, art and management. For the artist, the unicity, beauty, inspiration and creativity of art is doubled in the sale, marketing, display, distribution and mass production of “art works.” Making art is intimate, personal and individual; selling art requires public display, pleasing the all‐important customer(s) and dealing with many sorts of in‐betweens. What “commodification” is on the artist/art work level, is “doubling” on the I/me, self/persona, private/public, and in‐group/out‐group level.

The author proposes, from the example of quilt‐making, a wide‐ranging interrogation: “Is escape from commodification possible?”

Commodification doubles self and work, life and object, uniqueness and standardization and art and management. For the artist, the unicity, beauty, inspiration and creativity of art is doubled in the sale, marketing, display, distribution and mass production of “art works”. Making art is intimate, personal and individual; selling art requires public display, pleasing the all important customer(s) and dealing with many sorts of in-betweens. What commodification is on the artist/art work level is doubling on the I/me, self/persona, private/public and in-group/out-group level. This paper aims to examine the commodification and doubling in the case of the Gee’s Bend quilt makers. The quilts foreshadowed the modernist aesthetic and are of the highest aesthetic quality. But, they were made in a traditional rural society by very poor, uneducated black women. The quilts were not made to be sold but were dedicated to familial remembrance and to immediate aesthetic pleasure. But now that they are on display: is escape from commodification possible?

Reprint for special issue.

Doubling, in the original article below, was tendentious but artistically and politically to be overcome; doubling currently seems much more ominous, omnipresent and out of control. Signifyin(g) has become bomb throwing. Present day doubling apparently produces terror and not just commodification.

The purpose of this paper is to improve the understanding of the relationship between region-specific regulations of medications used in the manufacture of illegal drugs and illegal drug markets.

This paper examines a case study of the relationship between the regulation of medications containing pseudoephedrine in Czechia and neighbouring countries and the illegal drug market for methamphetamine in Czechia between 2006 and 2018. The description of this case is based on a review of the literature and a review of publicly available data sources.

The tightening of the regulation of medications containing pseudoephedrine in the Czech Republic led, in the years under study, to a gradual decrease in the number of packages sold and simultaneously to the illegal import of such medications from neighbouring countries with less strict regulations. At the same time, shifts in the drug market could be observed: the internationalisation of previously primarily domestic supply chains, the increased involvement of Vietnamese organised crime groups, the emergence of large-scale methamphetamine labs and a shift in production to countries with less strict regulations. The subsequent application of stricter controls in neighbouring countries was accompanied by further shifts in supply chains and increased imports from non-European countries.

The tightening of regulations of medications within a single country or single region might lead to significant and undesirable changes in drug markets and supply chains.

This paper provides a novel case study of the development of region-specific regulations of medications and their influence on illegal drug markets and supply chains in the Czech Republic and in the European context.

Medical devices are undergoing rapid changes because of the increasing affordability of advanced technologies like additive manufacturing (AM) and three-dimensional scanning. New avenues are available for providing solutions and comfort that were not previously conceivable. The purpose of this paper is to provide a comprehensive review of the research on developing prostheses using AM to understand the opportunities and challenges in the domain. Various studies on prosthesis development using AM are investigated to explore the scope of integration of AM in prostheses development.

A review of key publications from the past two decades was conducted. Integration of AM and prostheses development is reviewed from the technologies, materials and functionality point of view to identify challenges, opportunities and future scope.

AM in prostheses provides superior physical and cognitive ergonomics and reduced cost and delivery time. Patient-specific, lightweight solutions for complex designs improve comfort, functionality and clinical outcomes. Compared to existing procedures and methodologies, using AM technologies in prosthetics could benefit a large population.

This paper helps investigate the impact of AM and related technology in the field of prosthetics and can also be viewed as a collection of relevant medical research and findings.

The purpose of this study is to investigate barriers to the adoption of digital technologies (DTs) in the circular economy (CE) transition in the construction industry. The aim is to quantitatively investigate what the barriers to DTs-driven CE are in the Nigerian construction industry.

A review of existing literature identified 32 barriers to DTs-led CE. A well-structured quantitative research questionnaire was developed and administered to construction experts using a convenient sampling technique via hand delivery and Google form. The gathered data were analysed using arrays of both descriptive and inferential statistical methods.

The study revealed that the awareness of the digitalisation of CE is high, but the adoption is low. Five themes of the leading 10 factors responsible for the low adoption of DTs in CE transition in the Nigerian construction industry are (1) finance and demand barrier, (2) data management and information vulnerability, (3) skills shortage and infrastructure challenge, (4) poor government and management support and (5) interoperability and resistance problems.

This study could be helpful to decision-makers and policy formulators, which would provide an avenue for higher adoption of DTs in CE transition in the construction industry, better performance and environmental protection. It also provides a foundation for further research efforts in Nigeria and other developing countries of Africa and beyond.

Studies on the barriers to DT adoption in CE transition are still growing, and this is even non-existent in the Nigerian construction context. This offers a unique insight and original findings by pioneering the identification and assessment of barriers to the digitalisation of CE transition in Nigeria’s construction industry.

The purpose of this study (mixed-method) was to examine the effectiveness of two types of marketing interventions on water conservation behavior and to compare behaviors to self-reported conservation claims.

This paper consists of four phases (advertisement selection focus group, behavioral trace field study, self-report survey and follow-up focus group). In the USA, residing in a dormitory typically includes a fee for water without quantity restrictions. The subjects for this research were college students who lived in dormitories at a medium-sized university in southeastern USA where metering individual water consumption is not possible.

The results of the field study phase of student water conservation behaviors were not congruent with the participants’ self-reported behaviors. Phase 2 yielded results contrary to published laboratory experimental research in which cause-related claims were effective.

This research was limited by a single sample (one university), time (13 weeks) and the inability to measure individual consumption behavior. However, valuable findings were obtained, and suggestions surfaced for future research.

Using eco-feedback technology and advertisements may result in significant cost savings. While findings were somewhat inconclusive, there was evidence that the use of the eco-feedback technology could result in cost savings for the subject university.

The behavioral trace study is one of the first field research studies in the marketing discipline designed to examine resource conservation behavior in an impactful way. Further, this research used a single sample triangulated methodology across Phases 2, 3 and 4.

The purpose of this paper is to reflect on the author’s research experiences in northern Mozambique in order explore the multiplicity of gatekeeper relations that arose while seeking to arrange access to both “the field” and respondents, as well as the impacts that these relationships had on the research process. Although this dynamic has been thoroughly described within methodological literature, there exists a tendency to presume research–gatekeeper relations as static; once established, there is little discussion on how the relationships develop or can be managed, once access has (or has not) been achieved.

The paper draws upon qualitative fieldwork conducted predominantly in rural communities in northern Mozambique. The study analysed the development of the Nacala Development Corridor programme and the N13 Highway Rehabilitation Project in northern Mozambique in order to examine the impacts of the development on local citizens and examine the relationship between citizen and state within development processes. Fieldwork consisted of three different phases of semi-structured and open-ended interviews with key stakeholders and affected persons, spanning five different interview schedules, and a total of 77 individual interviews and 27 community focus groups conducted along the N13.

The study found that duality of Mozambican governance which includes both local officials and traditional leadership contributed to a multiplicity of local gatekeepers which impacted the research process in a multitude of ways. As a result, researcher–gatekeeper relations were not static, but had to be managed throughout the duration of the study.

This discussion provides a more dynamic representation of the challenges involved with establishing and managing gatekeeper relations in rural, developing, and in particular, southern African, contexts, while offering cautious practical advice to researchers working within rural or southern African contexts.

The purpose of this study is to develop a model for the selection of optimal development projects for an industrial complex (IC), aimed at improving its competitiveness.

Selection of optimal projects for IC development is carried out within the framework of a methodical approach to assessing and forecasting the competitiveness of IC based on the phased implementation of the following steps: assessment of the current level of competitiveness of an IC; optimization of the project portfolio aimed at improving the IC competitiveness; forecasting the IC competitiveness. The methodology for assessing the IC competitiveness is based on a comparative analysis of its activities against those of its leading competitors and evaluates two integral characteristics, namely, the level of current competitiveness and the indicator of the competitive potential. The methodical approach to the selection of the optimal portfolio of projects for the development of competitiveness is based on a step-by-step optimization of the portfolio using a dynamic programming procedure, which takes into account the implementation conditions of the projects, resource constraints and the prioritization of these projects. The targeted benchmark for the optimization is an integral indicator of IC competitiveness, comprising various aspects of its activities.

Method for multi-factor evaluation of IC competitiveness and the impact of a set of factors driving competitive advantage; set of benchmarks of IC competitiveness; the model for the selection and step-by-step optimization of the portfolio of IC development projects, aimed at increasing competitiveness in the context of resource constraints.

Methodology described in this paper was used to assess the competitiveness and optimize the project portfolio of Uralelektrotyazhmash Group of Enterprises (UETM), one of the largest power engineering complexes in Russia. The assessment was carried out in comparison with the leading domestic and global manufacturers of electrical equipment, which form UETM’s primary competition in the marketplace.

The study establishes a method for the comprehensive assessment of IC competitiveness based on the comparison of IC activity indicators with those of leading competitors. The proposed method defines an integral competitiveness index to allow for the quantitative assessment of IC competitiveness, development of measures to improve IC competitiveness and producing a methodology to forecast the impact of such measures; the study proposes a methodical approach to selecting the optimal portfolio of projects for the development of IC based on the stepwise optimization of such a portfolio while taking into account the conditions of their implementation, resource constraints and the impact on the indicator of competitiveness. This approach allows the IC to prioritize the implementation of the development projects and maximize its competitiveness in the context of available resources.
