Willingness-to-pay experimental model for Stackelberg dual channel pricing decision
Authors: Lin Shi-Woei , Januardi Januardi 
Published: September 2022

PurposeThis study proposes and demonstrates a novel approach to analyzing customer channel preferences and willingness-to-pay (WTP) in the dual sales channel (DSC) system involving direct online channels and conventional offline retailers, and to how the pricing decisions are made under specific game competition.Design/methodology/approachQuestionnaire survey based on central composite experiment design was utilized to obtain primary data. The model for customer channel preferences and WTP was then built by using multinomial logistic regression. The propensity of a customer to make purchases in either channel estimated by using the logit model was inserted in the bilevel programming model to formulate and solve for the Stackelberg competition where the conventional retailer acted as a leader.FindingsThe study found that channel prices have nonlinear impacts on WTP and channel preference. The empirical results complement the mathematical formulation well where high-order own-price and cross-price effects on channel selection are generally not analytical tractable. Under the Stackelberg competition, the traditional retailer (as the leader) still achieves higher profits than the online facility.Practical implicationsThe proposed framework provides an empirical approach that can easily address the competition model in the sales channel when complicated own-price or cross-price effects are present.Originality/valueThe present work provides a novel approach to analyze customer preference and WTP of the DSC systems. This alternative method simplifies the procedure for investigating and estimating price sensitivity, especially when the online and offline prices affect customer WTP and channel preferences nonlinearly. This model is also utilized in the game competition to facilitate data-driven price decision making to better formulate and understand real-world DSC problems.
The rationality of voluntary care work: light and shadow of volunteering in Germany's care sector
Authors: Haubner Tine 
Published: September 2022

PurposeIn the context of a care crisis in Germany, care work done by volunteers is increasingly being semi-formalized by the state and used in professional care work contexts to relieve families and professionals. However, voluntary care has not yet been adequately studied from a care-specific perspective. This study examines in what way voluntary care can be considered decent care from a care-ethical and empirical perspective.Design/methodology/approachConsidering findings of a qualitative interview study, the study examines the special features of voluntary care, addresses its socio-political expansion, and asks about the decency of voluntary care in elder care and social work.FindingsCare work done by volunteers is a special kind of care work, which has advantages but also disadvantages regarding care-ethical requirements of decent care. The study examines under which conditions voluntary care violates these requirements and how this can be countered in socio-political terms.Originality/valueVoluntary care is an under-researched phenomenon despite its increasing socio-political importance. While its state-led expansion can informalize and deprofessionalize care work at the expense of users, professionals, and volunteers, its analysis can help to illuminate the preconditions for decent care.
Cross-border M&A, greenfield FDI and the onset of intrastate conflict, 1990–2015
Authors: Beuck Erik , Shuaibi Nourah , Hwang Wonjae 
Published: September 2022

PurposeBy examining the link between the two types of FDI and intrastate conflict from 1990 to 2015 in 138 countries, this paper intends to test the peace-through-FDI thesis.Design/methodology/approachTo empirically test the hypotheses, this study examines county-year observations from 1990 to 2015 for 138 countries. An instrumental variable method is utilized to this end.FindingsThis paper shows that, while greenfield FDI generates pacifying effects on intrastate conflict, M&A investment is likely to promote the onset of intrastate conflict.Originality/valueDespite the extensive literature on FDI and the onset of intrastate conflict, many have approached FDI as a singular phenomenon, and have not broken it down into its constituent parts of greenfield and brownfield investment types. Theorizing that this practice had oversimplified and blurred the relationship of FDI on intrastate conflict onset, the authors pursued the collection of novel data in order to more completely distinguish between the two types of FDI. With this novel approach dividing FDI into its component parts, the authors break open the black box of FDI to empirically find out the extent of its diverse influence on the onset of intrastate conflict.
Developing together: the Finnish way of promoting sustainable public procurement
Authors: Berg Annukka , Alhola Katriina , Peltomaa Juha , Tietari Satu 
Published: September 2022

Purpose
Public procurement is a major driving force that can be used to advance societal goals such as sustainability. The lack of strategic management and top-level commitment have been found to be major hindrances to the promotion of sustainable public procurement (SPP). This study aims to examine the functioning of a successful Finnish SPP development programme, the KEINO Academy (2019–2020), that tackled these challenges in a holistic way.

Design/methodology/approach
The article is mainly based on qualitative analysis of interviews with 24 municipal representatives.

Findings
The KEINO Academy advanced SPP management through the following functions: legitimising SPP development work, structuring SPP development work, offering expert support and facilitating peer support. The functions were mainly able to meet the key challenges experienced by the participating municipalities. However, some challenges cannot be directly solved by an intermediary such as the KEINO Academy. These challenges include, for example, a lack of resources.

Social implications
On the basis of the study, SPP development programmes should: build a holistic working model; respect the versatility of the participating organisations; involve all the key people in the organisations, including the directors; and sustain change.

Originality/value
The main theoretical contribution is the combination of two streams of literature, those of SPP management and intermediary functions. Further, the article makes an empirical contribution by studying the KEINO Academy as a pioneering SPP development case.
An empirical study on financing constraints of digital inclusive finance development on small and medium-sized technology-based enterprise
Authors: Wang Xiongying , Chen Xiang 
Published: September 2022

PurposeThis paper mainly explores the relationship between digital inclusive finance and financing constraints of technological-based SMEs, and how digital inclusive finance affects the financing constraints of technology-based SMEs. This paper empirically analyzes the relationship between them through the OLS model, and then further verifies the relationship between them through robust regression and heterogeneity analysis. At the same time, it uses the mechanism test to explore how digital inclusive finance affects the financing constraints of technology-based SMEs. This paper aims to address these issues.Design/methodology/approachThis paper aims to explain the relationship between digital inclusive finance and financing constraints of technological-based SMEs. Technology-based SMEs always face the difficult problem of “financing difficulty” and “financing expensive” in the development process, which hinders the survival and development of enterprises to some extent. Digital inclusive finance development policy vigorously promoted by the state has alleviated the financing constraints of technology-based SMEs and brought opportunities for their development.FindingsThe results show that the role of digital inclusive finance in alleviating the financing constraints of technology-based SMEs, and incremental supplement and alleviating information asymmetry are the main reasons for digital inclusive finance to alleviate the financing constraints of technology-based SMEs. In view of the availability of digital inclusive financial data, this paper only uses the data from 2014 to 2019.Originality/valueThe authors’ research clearly found that the development of digital inclusive finance alleviates the financing of technology-based SMEs from the two aspects of “incremental supplement” and alleviating information asymmetry, so as to provide corresponding reference basis for the government to formulate a series of plans to support the development of technology-based SMEs.
Broadening the boundaries of accounting: a call for interdisciplinarity in the calculative era
Authors: Twyford Erin Jade , Abbas Roba 
Published: September 2022

Purpose
This paper aims to present a preliminary exploration of the intersections between the accounting and information systems (IS) disciplines. Using the illustrative example of the COVIDSafe app, released by the Australian federal government in response to the “wicked problem” of COVID-19, we demonstrate the value of interdisciplinarity to broaden the boundaries of accounting beyond a technical orientation to encompass social and moral considerations.

Design/methodology/approach
We apply a high-level view of socio-technical theory derived from the IS discipline by using a close-reading method of publicly available media and federal government sources related to the COVIDSafe app collected between April 2020 and April 2021. This theoretical lens allows for an enhanced understanding of the technical, environmental/regulatory, and social subsystems relating to accounting and accountability while supporting interdisciplinary reflection.

Findings
Addressing complex and wicked problems in accounting requires interdisciplinary approaches, whereby the accounting discipline must move beyond its technical origins. Dialogue between the accounting and IS disciplines is necessary to gain a deeper appreciation of the social, technical and moral implications of accounting in context.

Research limitations/implications
Viewing accounting beyond a technical practice through collaboration between accounting and IS offers a theorisation to consider the multi-dimensional nature of complex societal challenges. This theorisation can support the advancement of our practice and research meaningfully toward a view of accounting that centres on ideas of the public interest and the betterment of society. There remains much scope for progressing this dialogue, and we commend other scholars to engage in interdisciplinary work on the boundaries of accounting.

Originality/value
This study illustrates opportunities for accounting and IS approaches to solving “grand challenges”. Further, the study answers multiple calls for interdisciplinary discourse in accounting scholarship by contributing a socio-technical framing toward addressing complex challenges in our calculative era by initiating a dialogue that moves beyond accounting's traditional technical practice or the “accounting information systems” context.
Does product market competition moderate the impact of promoter ownership on firm value?
Authors: Anuja Sethiya , M. Thenmozhi 
Published: September 2022

PurposeThis study explores whether product market competition is a substitute for or complementary to good internal governance through promoter holdings. Specifically, it examines the impact of product market competition on the linkage between promoter ownership and firm value and investigates whether this impact varies with the type of blockholders and level of ownership.Design/methodology/approachThe authors used a fixed-effect panel regression method to analyze 1,136 National Stock Exchange-listed firms with 10,770 observations between the years 2005 and 2017. The authors computed product market competition using the Hirschman–Herfindahl Index and used the two-stage least squares regression model to address the issue of endogeneity.FindingsCompetition is a substitute for good corporate governance, especially in highly competitive industries, while promoters enhance firm value only in less competitive industries. This supports the theory that competition hinders a manager's “quiet life” hypothesis and creates disciplinary pressure to perform well. Additionally, the authors find that competition acts as a complement to promoters who are state-owned blockholders, while it acts as a substitute for promoters who are family-owned and private-owned blockholders.Originality/valueThis is possibly among the earliest attempts to integrate promoter ownership, product market competition, and firm value with the type of blockholder, especially in the context of the Indian market after 2005. The authors also provide evidence of situations in which both external and internal governance mechanisms either synergize or mitigate each other.
Mobile banking affordances and constraints by the elderly
Authors: Castillo-Villar Fernando Rey , Castillo-Villar Rosalia G. 
Published: September 2022

PurposeThe study explores the affordances and constraints perceived by older adults through their experiences using mobile banking apps.Design/methodology/approachTwenty-five interviews via Skype were carried out with older adults aged 65 years and over between April and May 2021 (during the COVID-19 pandemic).FindingsBased on their usage experiences with mobile banking, older adults identified functional (saving time, avoiding physical risk and having control over their finances) and social affordances (supporting and bonding with family and friends), as well as non-technological (lack of useful information and patience from bank employees) and technological constraints (concerns about cybersecurity, data privacy and passwords).Originality/valueThe study offers a novel approach to customer experience research in mobile banking by adopting a customer-centered perspective and applying the theoretical framework of affordances and constraints to analyze the experiences of older adults as active mobile banking users.
Impact of zirconia slurry in steel powder on melt pool characteristics in laser powder bed fusion
Authors: Davis Taylor , Nelson Tracy W. , Crane Nathan B. 
Published: September 2022

Purposedding dopants to a powder bed could be a cost-effective method for spatially varying the material properties in laser powder bed fusion (LPBF) or for evaluating new materials and processing relationships. However, these additions may impact the selection of processing parameters. Furthermore, these impacts may be different when depositing nanoparticles into the powder bed than when the same composition is incorporated into the powder particles as by ball milling of powders or mixing similarly sized powders. This study aims to measure the changes in the single bead characteristics with laser power, laser scan speed, laser spot size and quantity of zirconia nanoparticle dopant added to SS 316 L powder.Design/methodology/approachA zirconia slurry was inkjet-printed into a single layer of 316 SS powder and dried. Single bead experiments were conducted on the composite powder. The line type (continuous vs balling) and the melt pool geometry were compared at various levels of zirconia doping.FindingsThe balling regime expands dramatically with the zirconia dopant to both higher and lower energy density values indicating the presence of multiple physical mechanisms that influence the resulting melt track morphology. However, the energy density required for continuous tracks was not impacted as significantly by zirconia addition. These results suggest that the addition of dopants may alter the process parameter ranges suitable for the fabrication of high-quality parts.Originality/valueThis work provides new insight into the potential impact of material doping on the ranges of energy density values that form continuous lines in single bead tests. It also illustrates a potential method for spatially varying material composition for process development or even part optimization in powder bed fusion without producing a mixed powder that cannot be recycled.
Lexical gap between old and new generations in a Jizani dialect: a sociolinguistic mixed method study
Authors: Hakami Fahad Ali 
Published: September 2022

PurposeThis study aims to identify and measure the lexical gap between the old and young generations in the Jizani dialect and determine the causes of that gap.Design/methodology/approachA 20-item questionnaire was distributed randomly among 104 participants. Next, 12 participants were selected and interviewed. SPSS software was used to analyse the quantitative data from the questionnaire. The data elicited from the interviews was qualitatively analysed, considering age and gender factors.FindingsThe major findings revealed that a lexical gap between old and young language speakers in the Jizani dialect exists. The gap between young females and the older generation was greater than that between young and old males. Some old words are likely to disappear in the coming decades. Social media, which is a time-consuming and word-borrowing medium for young people, was one of the reasons, besides the tendency of females to use prestigious words.Originality/valueThis study attempted to find the differences between the vocabularies of old and young speakers. If it does exist, is it significant? What are the reasons for this lexical gap? This will help other researchers and dialectologists register the old words before they die out and try to bridge that lexical gap.
Experimental behavior and reliability of predamaged concrete columns externally repaired with FRP spiral strips under axial compression
Authors: Ali Ahmed Chafika , Si Salem Abdelmadjid , Ait Taleb Souad , Ait Tahar Kamal 
Published: September 2022

Purpose
This paper aims to investigate the experimental behavior and the reliability of concrete columns repaired using fiber-reinforced polymers (FRPs) under axial compression loading. The expression of the ultimate axial resistance was assessed from the experimental data of damaged concrete cylinders repaired by externally bonded double-FRP spiral strips.

Design/methodology/approach
The tested columns bearing capacity mainly depends of the elasticity modulus of both damaged and undamaged concrete have been considered in addition to the applied load and the cylinder diameter as random variables in the expression of the failure criterion. The reliability indicators were assessed using first order second moment method.

Findings
The emphasized test results, statistically fitted show that the strength has been retrofitted for all repaired specimens whatever the degree of initial damage. However, the gain in axial strength is inversely proportional to the degree of damage.

Originality/value
The efficiency of a new FRP repair procedure using double-spiral strips was studied. This research provides a technical and economical solution for retrofitting existing concrete columns. Finally, the random character of the variables that govern the studied system shows the accuracy and safety of the proposed original design.

Abstract

Climate, topography and the 3D structure of forests are major drivers affecting local species communities. However, little is known about how the specific functional traits of saproxylic (wood‐living) beetles, involved in the recycling of wood, might be affected by those environmental characteristics.

Here, we combine ecological and morphological traits available for saproxylic beetles and airborne laser scanning (ALS) data in Bayesian trait‐based joint species distribution models to study how traits drive the distributions of more than 230 species in temperate forests of Europe.

We found that elevation (as a proxy for temperature and precipitation) and the proportion of conifers played important roles in species occurrences while variables related to habitat heterogeneity and forest complexity were less relevant. Furthermore, we showed that local communities were shaped by environmental variation primarily through their ecological traits whereas morphological traits were involved only marginally. As predicted, ecological traits influenced species' responses to forest structure, and to other environmental variation, with canopy niche, wood decay niche and host preference as the most important ecological traits. Conversely, no links between morphological traits and environmental characteristics were observed. Both models, however, revealed strong phylogenetic signal in species' response to environmental characteristics.

These findings imply that alterations of climate and tree species composition have the potential to alter saproxylic beetle communities in temperate forests. Additionally, ecological traits help explain species' responses to environmental characteristics and thus should prove useful in predicting their responses to future change. It remains challenging, however, to link simple morphological traits to species' complex ecological niches.

Examination of the possibility to use Siamese networks for the comparison of firing pin marks
Authors: Giverts Pavel , Sorokina Ksenia , Fedorenko Vladimir 
Published: September 2022

AbstractOne of the most discussed issues in forensic firearms identification is the subjectivity of conclusions. The main part of firearms examiners' work is to make a microscopic comparison of the marks on cartridge cases and bullets. In this process, examiners have to decide if the quantity and the quality of the observed characteristics are sufficient for identification. This decision is based on the personal experience of an examiner, so examiners with different backgrounds can come to different conclusions, and this fact presents a problem. Besides, the calculation of the error rate for this type of examination is a debatable issue. Different mathematical and statistical models were proposed, and computer‐based algorithms were developed in order to avoid subjectivity and to determine error rates. This article investigates the possibility to use methods of machine learning for the comparison of marks of the firing pin impressions on cartridge cases. In the research, the Siamese network model, which included two similar Convolutional Neural Networks, was prepared and trained. For the training and validation of the model, the database of firing pin impressions was prepared. This database included images of cartridge cases discharged from 300 firearms that came from regular casework and clone images used for data augmentation. The model was trained and examined using the validation part of the database. The metrics, such as accuracy, sensitivity, and specificity were calculated. The results of the research show the possibility of using the Siamese network for building an objective forensic firearms examination system with a known error rate.
