Abstract

Purpose

The purpose of this paper is to explore informational structures producing and organising the construction of waste sorting in Sweden. It shows how the issue is constructed by it being searched for in Google and how this contributes to the specific informational texture of waste sorting in Sweden. It is guided by the following questions: who are the main actors and which are the central topics featuring in Google results on popular, suggested searches for waste sorting in Sweden? What do the link relations between these tell the author about the issue space that is formed around waste sorting in Sweden? How is the construction of the notions of waste sorting and waste shaped in the information available through Google’s features for related and other relevant searches?

Design/methodology/approach

Waste sorting is discussed as a practice structured along moral rules and as a classification exercise. The study brings together two types of material, results from searches carried out in Google and lists of Google query suggestions for relevant search terms. These are analysed with a mixed method approach, uniting quantitative network analysis and qualitative content analysis of query suggestions. A sociomaterial approach theoretically grounds the analysis.

Findings

Waste sorting in Sweden emerges as an issue that is characterised by dense networks of rules and regulation, focused in public authorities and government agencies, which in turn address consumers, waste management businesses and other authorities. Search engine use and waste sorting in Sweden are shown to be joined together in various mundane everyday life practices and practices of governance that become visible through the search engine in form of search results and suggested searches. The search engine is shown to work as a fluid classification system, which is also created and shaped by its use.

Originality/value

The study offers a novel methodological approach to studying the informational structures of an issue and of its shaping through it being searched for. The sociomaterially grounded analysis of Google as a fluid classification system is original.

Abstract

Purpose

Qualitative researchers and information practitioners often investigate questions that probe the underlying mental models, nuanced perspectives, emotions and experiences of their target populations. The in-depth qualitative interview is a dominant method for such investigations and the purpose of this paper is to demonstrate how incorporating hybrid card-sorting activities into interviews can enable deeper participant reflections and generate rich data sets to increase understanding.

Design/methodology/approach

Following a review of relevant literature, the case illustration presented is a grounded theory study into the student-researcher information experience with personal academic information management. This study uses hybrid card sorting within in-depth, semi-structured interviews, a unique adaptation that extends multi-disciplinary awareness of the benefits of card-sort exercises for qualitative research.

Findings

Emerging from diverse fields, ranging from computer science, engineering, psychology and human–computer interaction, card sorting seeks to illuminate how participants understand and organise concepts. The case illustration draws largely on methods used in interaction design and information architecture. Using either open or fixed designs, or hybrid variations, card-sort activities can make abstract concepts more tangible for participants, offering investigators a new approach to interview questions with the aid of this interactive, object-based technique.

Originality/value

Opening with a comprehensive review of card-sort studies, the authors present an information experience case illustration that demonstrates the rich data generated by hybrid card sorting within qualitative interviews, or interactive interviews. This is followed by discussion of the types of research questions that may benefit from this original method.

Abstract

Purpose

Travel interests of tourists during pandemics and outbreaks are reduced due to the prevalence of fear. It induces lifestyle changes, which may hinder efforts to recover the tourism value chain during post-COVID-19 lockdowns. Subscribing to domestic travel and domestic tourism is deemed to mitigate fear and gradually reopen the tourism industry. Although a crucial initiative, evaluating the perceived degree of exposure of tourists to COVID-19 in tourist sites operating under domestic tourism has not been fully explored in the emerging literature, which forms the main departure of this work.

Design/methodology/approach

The problem domain is addressed by adopting multiple criteria sorting method – the VIKORSORT. To demonstrate such application, with 221 survey participants, 35 tourist sites in a province in the central Philippines struggling to revive the tourism industry are evaluated under six attributes that characterize tourists' exposure to COVID-19. To assess its efficacy, the performance of the VIKORSORT is compared to other distance-based multiple criteria sorting methods (i.e. TOPSIS-Sort and CODAS-SORT).

Findings

Results show that proximity and volume of tourist arrivals are considered on top of the priority list of attributes. The use of VIKORSORT yields the assignment of 27 sites to the “moderate exposure” class, and eight under the “high exposure” class, with no tourist site assigned to the “low exposure” class. Sorting the tourist sites reveals some observations that tourists prefer sites (1) with open spaces, (2) with activities having limited group dynamics, (3) that are nature-based, and (4) with tourist arrivals that are not relatively high, with enough land area to practice social distancing. In addition, the assignments of the VIKORSORT with TOPSIS-Sort and CODAS-SORT are consistent at least 90% of the time, demonstrating its efficacy in addressing multiple criteria sorting problems.

Originality/value

This work provides an integrative approach in evaluating tourist sites in view of tourism recovery during pandemics. The findings offer crucial insights for the primary stakeholders (i.e. government, tourist operators, and tourists) in planning, resource allocation decisions, and policy formulation. Policy insights are offered, as well as avenues for future works.

Abstract

Purpose

The purpose of this article is to explore possible contributions to the development of models to define business networks conceptually, and identify and delineate them empirically by integrating concepts and ideas from “market exchange theory” originating in the works of Alderson.

Design/methodology/approach

Following a conceptual discussion defining business networks as a type of exchange system, empirical data were used to exemplify and illustrate the theoretical development ideas. From data on 22 business firms collected in 1999‐2001 in the form of transcribed interviews and other print documentation, a business network as a type of exchange system was identified comprising five business entities. This case serves as illustration to the remainder of the theoretical discussions throughout the paper.

Findings

Based on a conceptualisation of business networks as a type of exchange system and a notion of interaction encompassing exchange processes stemming from both market exchange theory and social exchange theory, it is suggested that business networks can be more consistently identified and delineated empirically using this theoretical base.

Research limitations/implications

The empirical case is merely illustrative, and more extensive empirical work is needed to further test the ideas of business networks as a type of exchange system. The implications to the study of markets‐as‐networks are that these ideas can be used as a basis for identification, delineation and analysis of business networks.

Originality/value

This paper extends Alderson's work by suggesting a fourth type of transformation: transformation in ownership, as well as by developing a typology with five resource types in the exchange system. Furthermore, it provides a conceptual tool that can be used by researchers to identify, delineate and analyse business networks and incorporates market exchange theory.

Abstract

Purpose

Efficient and high-accuracy intelligent color and material sorting systems are the main bottlenecks restricting the recycling of waste textiles. The mixing of waste textiles with different colors will make the reconstructed raw material of textile fiber useless or with low quality. In this study, some challenges about the automatic color sorting for waste textile recycling are discussed. A computer vision-based color sorting system for waste textile recycling is introduced, which can classify the required colors well and meet the efficiency requirements of an automatic recycling line.

Design/methodology/approach

There are four aspects, (1) two cameras with different exposure times and white-balance parameters are involved for establishing the computer vision system. (2) Two standard color databases with two cameras are constructed. (3) A statistical model to determine the colors of textile samples is presented in which uniform sampling of pixels and mid-tone enhancing techniques are exploited. (4) The experiments with a number of waste textile samples from a factory in Hong Kong are conducted to illustrate the efficiency of the developed system.

Findings

The experiments with a number of waste textile samples from a factory in Hong Kong are reported. The total classification accuracy performs good. The research methods and results reported in this study can provide an important reference for improving the intelligent level of color sorting for waste textile recycling.

Originality/value

It is the first time to introduce computer vision technology to a color sorting system for recycling waste textiles, especially in a real recycling factory in Hong Kong. The research methods and results reported in this study also deliver guidance for designing a computer vision-based color sorting system for other industrial scenarios.

Abstract

Purpose

The purpose of this paper is to provide a decision support tool for construction waste on‐site to achieve better construction and demolition waste management.

Design/methodology/approach

System dynamics methodology is adopted for developing the model.

Findings

The model of managing construction waste on‐site is established. The interconnections of the main activities are included into the model with focus on planning and management where information about the future trend is for better decision making.

Practical implications

Construction waste generation is dynamic and interactive. Therefore, the model developed can be used as a flexible tool to help practitioners to understand the causes and effects.

Originality/value

Since the model allows the users to fine‐tune the input parameters, it is flexible to adjust the model to better reflect the reality according to different conditions. This is an advantage over other static models.

Abstract

Purpose

The purpose of this paper is to find a convenient contact detection algorithm in order to apply in distinct element simulation.

Design/methodology/approach

Taking the most computation effort, the performance of the contact detection algorithm highly affects the running time. The algorithms investigated in this study consist of Incremental Sort-and-Update (ISU) and Double-Ended Spatial Sorting (DESS). These algorithms are based on bounding boxes, which makes the algorithm independent of blocks shapes. ISU and DESS algorithms contain sorting and updating phases. To compare the algorithms, they were implemented in identical examples of rock engineering problems with varying parameters.

Findings

The results show that the ISU algorithm gives lower running time and shows better performance when blocks are unevenly distributed in both axes. The conventional ISU merges the sorting and updating phases in its naïve implementation. In this paper, a new computational technique is proposed based on parallelization in order to effectively improve the ISU algorithm and decrease the running time of numerical analysis in large-scale rock mass projects.

Originality/value

In this approach, the sorting and updating phases are separated by minor changes in the algorithm. This tends to a minimal overhead of running time and a little extra memory usage and then the parallelization of phases can be applied. On the other hand, the time consumed by the updating phase of ISU algorithm is about 30 percent of the total time, which makes the parallelization justifiable. Here, according to the results for the large-scale problems, this improved technique can increase the performance of the ISU algorithm up to 20 percent.

Abstract

Purpose

The purpose of this paper is to study the performances of “pick‐and‐sort” order‐picking systems (OPSs) and investigate picking efficiency and design issues as a function of the number and length of the picking waves.

Design/methodology/approach

An analytical model is proposed to estimate the picking efficiency as a function of wavelength. The model, which has been tested by simulations, includes an algorithm to estimate the expected overlapping of order lines. Finally, a case study illustrates the use of the model in the initial assessment phase of OPS design, and resolves the trade‐off between picking efficiency and sorting cost.

Findings

The effect of the wavelength on picking efficiency is calculated.

Research limitations/implications

The trade‐off analysis between picking efficiency and sorting cost refers to a specific sorting system and picking area layout.

Practical implications

The paper provides a tool to support the design of “pick‐and‐sort” OPS, where the importance of the length of the picking wave emerges.

Originality/value

This paper presents an innovative model that can be used in the initial phase of “pick‐and‐sort” OPS design.

Abstract

Purpose

This chapter tests whether adolescent counter-normative behaviors increase voluntary and involuntary job exits in young adults. This prediction extends the social sorting view of employment outcomes to cover concealable background characteristics, which has implications for involuntary mobility after entering the job.

Methodology

The National Longitudinal Survey of Youth (NLSY) 1997 data are analyzed through survey-weighted Cox models of involuntary and voluntary job change. The key variables are adolescent use of alcohol and illegal drugs, and early sexual debut.

Findings

The findings show that sex and use of drugs in the early teens increase involuntary job exits, controlling for current behaviors, but do not have discernible effects on voluntary job exits. The effects of adolescent behavior appear stronger in multi-establishment firms and for Hispanic and black individuals.

Social implications

The findings indicate that employee sorting of individuals based on background does not end at the point of hiring, but continues through post-hiring rates of job exit. The findings indicate differential treatment of employees as a function of stigmatized behaviors in the past, and thus reveal a form of discrimination that has not been investigated earlier.

Value of the chapter

The findings in the chapter provide support for a theoretical view of social sorting by the employer as a driver of job exits. It extends the scope of characteristics that may result in social sorting to those who are concealable at the point of hiring, and with consequences after hiring. Because these include adolescent behaviors that are stigmatized, it shows a new mechanism linking adolescent experiences with adult work outcomes.

Abstract

Variable pay, defined as pay that is tied to some measure of a firm’s output, has become more important for executives of the typical American firm. Variable pay is usually touted as a way to provide incentives to managers whose interests may not be perfectly aligned with those of owners. The incentive justification for variable pay has well-known theoretical problems and also appears to be inconsistent with much of the data. Alternative explanations are considered. One that has not received much attention, but is consistent with many of the facts, is selection. Managers and industry specialists may have information about a firm’s prospects that is unavailable to outside investors. In order to induce managers to be truthful about prospects, owners may require managers to “put their money where their mouths are,” forcing them to extract some of their compensation in the form of variable pay. The selection or sorting explanation is consistent with the low elasticities of pay to output that are commonly observed, with the fact that the elasticity is higher in small and new firms, with the fact that variable pay is more prevalent in industries with very technical production technologies, and with the fact that stock and stock options are a larger proportion of total compensation for higher level employees. The explanation fits small firms and start-ups better than larger, well-established firms.
