Variation, replication and selection in evolving industries
Authors: Grandinetti Roberto 
Published: December 2020

PurposeVariation, replication and selection processes are acknowledged as key constructs in studies on how industries evolve, but no theoretical and empirical contributions have applied these key constructs to analyzing industries in specific stages of their history. This paper aims to fill this gap, taking for reference the firm and its strategic action in particular.Design/methodology/approachAfter delineating and discussing the three processes of interest – variation, replication and selection – this paper analyzes three very different evolutionary contexts: “red” industries, that reached maturity maintaining a polypolistic structure, and that continue to evolve in this phase; the oligopolistic transformation undergone by certain industries; and the emergence of new market spaces around new products developed by firms.FindingsVariations are mainly reactions to the competitive environment in the evolution of red industries or environment-modifying in the case of industries evolving toward an oligopoly, and in the creation of new market spaces. Horizontal replication through employee mobility prevails in red industries, while in the other two contexts firms driving the evolution raise barriers to replication, inhibiting both horizontal and vertical replication. While selection does not come about in a new market space as long as the barriers erected by the first comer remain in place, it occurs in the form of subset selection in the other two settings.Originality/valueThis paper takes an entirely novel approach and proposes a pluralist framing of how industries evolve, interpreting the different evolutionary situations on the strength of the key variables of variation, replication and selection.

Published: December 2020

PurposeThe relationship between job satisfaction and performance is a topic that has been intriguing scholars and managers for a long time. With the flourishing of positive psychology, it has been called the happy-productive worker thesis. New concepts led to new results but still divergent. This study aims to understand the past 20 years of research on the topic, also called the holy grail of the organizational sciences, helping to unwrap conclusions so far.Design/methodology/approachBibliometric analysis was performed with R statistical tool’s support, complemented by content analysis, based on studies from three major databases between 1999 and 2019. The empirical studies were analyzed according to the constructs used, shedding light on when the happy-productive worker thesis is more likely to be confirmed.FindingsResults show a variety of constructs and instruments used to operationalize the constructs. This lack of convergence accounts for a large part of the general inconclusiveness of the topic. Indicated research gaps can be useful to both academics and practitioners.Research limitations/implicationsOnly studies declared as related to the happy-productive worker thesis were considered.Practical implicationsManagers can benefit from considering the findings as a basis for decision-making regarding investments in employee happiness at work, focusing on the aspects of happy constructs that lead to productive criteria.Originality/valueThe application of mixed methods, complementing the bibliometric with thorough content analysis, provided a more detailed overview of current knowledge about the topic, helping to disentangle different concepts that were treated as similar. Thus, it is possible to understand in which situations happy workers are really more productive.
Advertising on till receipts in socialist Czechoslovakia: language, argumentation and ideology
Authors: Dufek Ondřej 
Published: December 2020

Purpose
This paper aims to provide a description of the language of advertising in socialist Czechoslovakia (1948-1989) and to offer an understanding of its nature. It focuses on significant linguistic characteristics of the discourse and on the means of argumentation and persuasion.

Design/methodology/approach
Linguistic investigation of the grammar and pragmatics of language used and content analysis studying the lexical level of ads while also considering the broader context in the way of discourse analysis.

Findings
The paper shows that statements are the most frequent utterance type across all the decades and appeals, which one could associate with a direct and strong addressee orientation (and, perhaps, authoritarian system, too), are only present marginally. Concerning what is advertised, the promotion of manufacturer/seller is frequent compared to specific products. A category of product type was relatively important, especially in the 1950s and 1960s. Unlike capitalist advertising, socialist promotion shows also instances of socio-educational and state-political promotion.

Originality/value
As no such study was conducted so far, this paper shows that Czechoslovak socialist advertising constructed an imagination that was very much dependent on consumerism just like advertising in Western capitalist countries, and at the same time, it was reflecting specific socio-political circumstances.
Interactive service quality on the acceptance of self-service ordering systems for the restaurant industry
Authors: Yang Ting , Lai Ivan Ka Wai , Fan Zhao-Bin , Mo Qing-Min 
Published: December 2020

Purpose
The purpose of this paper is to identify the factors that explain the acceptance of self-service ordering systems (SOSs) for restaurants and to explore the effects of “self-service system service quality” (SSQ) and “interpersonal service quality” (ISQ) on the acceptance factors extended from the Unified Theory of Acceptance and Use of Technology model.

Design/methodology/approach
This study targets customers who have recently used SOSs to order foods in middle-class restaurants. In total, 402 valid survey samples were obtained. Partial least squares (PLS) analysis was used to examine the factors of user acceptance of using SOSs.

Findings
The results of the PLS-SEM analysis indicate that SSQ has a significant effect on accuracy expectancy, speed expectancy and effort expectancy; ISQ has a significant effect on accuracy expectancy, speed expectancy, effort expectancy and facilitating conditions; and accuracy expectancy, speed expectancy, effort expectancy, social influence, facilitating conditions and budget expectancy significantly influence user acceptance of SOSs. Furthermore, user experiences moderate the effect of speed expectancy and effort expectancy on user acceptance.

Originality/value
This study introduces three technology acceptance factors (accuracy, speed and budget) for researchers to consider in the future. It also extends the knowledge about the human service factor when middle-class restaurants adopt self-service technologies (SSTs). Recommendations are provided for system developers to improve the system quality of SSTs and service staff to rethink their roles in adopting SSTs in the service industry.
A maximal covering facility location model for emergency services within an M (t)/M/m/m queuing system
Authors: Bahrami Iman , Ahari Roya M. , Asadpour Milad 
Published: December 2020

Purpose
In emergency services, maximizing population coverage with the lowest cost at the peak of the demand is important. In addition, due to the nature of services in emergency centers, including hospitals, the number of servers and beds is actually considered as the capacity of the system. Hence, the purpose of this paper is to propose a multi-objective maximal covering facility location model for emergency service centers within an M (t)/M/m/m queuing system considering different levels of service and periodic demand rate.

Design/methodology/approach
The process of serving patients is modeled according to queuing theory and mathematical programming. To cope with multi-objectiveness of the proposed model, an augmented ε-constraint method has been used within GAMS software. Since the computational time ascends exponentially as the problem size increases, the GAMS software is not able to solve large-scale problems. Thus, a NSGA-II algorithm has been proposed to solve this category of problems and results have been compared with GAMS through random generated sample problems. In addition, the applicability of the proposed model in real situations has been examined within a case study in Iran.

Findings
Results obtained from the random generated sample problems illustrated while both the GAMS software and NSGA-II almost share the same quality of solution, the CPU execution time of the proposed NSGA-II algorithm is lower than GAMS significantly. Furthermore, the results of solving the model for case study approve that the model is able to determine the location of the required facilities and allocate demand areas to them appropriately.

Originality/value
In the most of previous works on emergency services, maximal coverage with the minimum cost were the main objectives. Hereby, it seems that minimizing the number of waiting patients for receiving services have been neglected. To the best of the authors’ knowledge, it is the first time that a maximal covering problem is formulated within an M (t)/M/m/m queuing system. This novel formulation will lead to more satisfaction for injured people by minimizing the average number of injured people who are waiting in the queue for receiving services.
Perception of customer retail experiences in Poland
Authors: Kacprzak Agnieszka , Dziewanowska Katarzyna 
Published: December 2020

Purpose
Poland’s political and economic transition of 1989 resulted in a cultural trauma experienced by consumers, which has influenced their perception of the retail experience. However, younger Polish consumers can remember neither communism nor the transition period. Therefore, this study aims to investigate the differences in perception of customer experiences in retail between Poland’s pre- and post-transitional generations.

Design/methodology/approach
A quantitative survey is first conducted with a sample of 1,045 Polish consumers measuring their perception of utilitarian and hedonic customer experiences in retail environments. Then, five qualitative focus group interviews with 29 participants provide an in-depth understanding of the survey results.

Findings
The quantitative study suggests that the pre-transitional generation is focused on utilitarian experiences, whereas the post-transitional generation is attracted to hedonic experiences in retail environments. The qualitative study provides an understanding of how the utilitarian and hedonic aspects of customer retail experiences are perceived and how the cultural trauma manifests in consumers’ values.

Originality/value
The study provides a new perspective on the customer experience in retail contexts from a society that has undergone a cultural trauma. The findings focus on generational differences in consumer attitudes toward hedonic and utilitarian experiences in a post-transition society and expand the theory of cultural trauma into the field of customer retail experience.
Direct and Indirect Effects of Forest Harvesting on Sediment Yield in Forested Watersheds of the United States
Authors: McEachran Zachary P. , Karwan Diana L. , Slesak Robert A. 
Published: December 2020

AbstractManaged forests generally produce high water quality, but degradation is possible via sedimentation if proper management is not implemented during forest harvesting. To mitigate harvesting effects on total watershedsediment yield, it is necessary to understand all processes that contribute to these effects. Forest harvesting best management practices (BMPs) focus almost exclusively on overland sediment sources, whereas in‐and‐near stream sources go unaddressed although they can contribute substantially to sediment yield. Thus, we propose a new framework to classify forest harvesting effects on stream sediment yield according to their direct and indirect processes.Direct effectsare those caused by erosion and sediment delivery to surface water from overland sources (e.g., forest roads).Indirect effectsare those caused by a shift in hydrologic processes due to tree removal that accounts for increases in subsurface and surface flows to the stream such that alterations in water quality are not predicated upon overland sediment delivery to the stream, but rather in‐stream processes. Although the direct/indirect distinction is often implicit in forest hydrology studies, we have formalized it as a conceptual model to help identify primary drivers of sediment yield after forest harvesting in different landscapes. Based on a literature review, we identify drivers of these effects in five regions of the United States, discuss current forest management BMPs, and identify research needs.
18F‐Fluoroestradiol PET in the evaluation of probable oligometastatic breast cancer
Authors: Denton Matthew , Taubman Kim , Sutherland Tom 
Published: December 2020

SummaryRecent advances with specific PET tracer ligands, for example prostate‐specific membrane antigen (PSMA)‐based PET imaging, have substantially improved the sensitivity and specificity of PET imaging. 18F‐Fluoroestradiol (FES) is a novel PET tracer that has been demonstrated to have high specificity for oestrogen receptor (ER) in breast cancer. This case describes the use of FES‐PET to further characterise a solitary scapular lesion in a patient with locally advanced ER‐positive breast cancer. In demonstrating FES avidity in the lesion, it was determined to represent metastatic disease, thus avoiding further biopsy with its associated morbidity. This case demonstrates the potential diagnostic utility of FES PET‐CT in the management of ER‐positive breast cancer patients with probable oligometastatic disease.
Transnational Multistakeholder Partnerships as Vessels to Finance Development: Navigating the Accountability Waters
Authors: Erdem Türkelli Gamze 
Published: December 2020

AbstractPartnerships have long been presented as transformative and effective mechanisms to overcome challenges linked to the global governance of development. The 2030 Agenda for Sustainable Development and SDG 17 call for intensified involvement and engagement of partnerships in sustainable development, formalizing a role specifically for multi‐stakeholder partnerships (MSPs). In this context, transnational MSPs that enmesh public and private to finance development, continue to flourish as a hybrid model of governance. This paper seeks to critically assess the accountability issues linked to channelling development financing through transnational MSPs using an accountability matrix, based on responsibility, answerability and enforceability, applicable to the system‐level development cooperation/aid frameworks as well as to MSPs. The article then evaluates the accountability challenges and shortcomings arising from MSPs as development financing actors resulting in diffused responsibility, limited answerability and weak enforceability. Finally, the article outlines a research agenda and Policy recommendations to improve the accountability of MSPs when they finance development.
Lifting the numbers game: identifying key input variables and a best‐performing model to detect financial statement fraud
Authors: Gepp Adrian , Kumar Kuldeep , Bhattacharya Sukanto 
Published: December 2020

AbstractThis study enables practitioners and researchers to make an informed choice for a financial statement fraud detection model, rather than defaulting to popular, yet dated, models. Using a specifically devised performance criterion, our newly configured ensemble outperforms 31 others in the most comprehensive comparison to date spanning parametric, non‐parametric, big data and ensemble techniques. We use a large set of input variables and holdout data relative to prior studies. We find empirical support for financial and non‐financial variables covering the three Fraud Triangle factors. New findings include fraud risk being reduced with more debt, likely from increased monitoring by creditors.

AbstractPrescription stimulants, such as d‐amphetamine or methylphenidate are used to treat suffering from attention‐deficit hyperactivity disorder (ADHD). They potently release dopamine (DA) and norepinephrine (NE) and cause phosphorylation of the α‐amino‐3‐hydroxy‐5‐methyl‐4‐isoxazolepropionic acid (AMPA) receptor subunit GluA1 in the striatum. Whether other brain regions are also affected remains elusive. Here, we demonstrate that d‐amphetamine and methylphenidate increase phosphorylation at Ser845 (pS845‐GluA1) in the membrane fraction of mouse cerebellum homogenate. We identify Bergmann glial cells as the source of pS845‐GluA1 and demonstrate a requirement for intact NE release. Consequently, d‐amphetamine‐induced pS845‐GluA1 was prevented by β1‐adenoreceptor antagonist, whereas the blockade of DA D1 receptor had no effect. Together, these results indicate that NE regulates GluA1 phosphorylation in Bergmann glial cells in response to prescription stimulants.

AbstractGrasslands are valued by their capacity to store carbon (C) as well as by their livestock production. However, focussing grassland management on one of these characteristics might negatively affect the other. Here, we describe for the first time the amount of C stored in the plant and soil compartments of extensively grazed highland grasslands of central Argentina. We quantified C stocks of standing plant, litter, and roots biomass, and soil (0–100 cm depth) in three coexisting grassland types associated with different livestock use: lawns and open and closed tussock grasslands (from higher to lower grazing use) and analysed how those stocks vary across grassland types. Our main results showed that these mountain grasslands represent an important regional C reservoir, with total C stocks (plant plus soil) ranging from 110 to 472 Mg C ha−1, with more than 95% of C being stored in soils. Differences in soil C stocks up to 30 cm depth were not associated with grassland types. However, in grazing lawns (higher livestock use), belowground plant C increased, whereas aboveground plant C was reduced. Overall, resulting in a 14% lower C stored in the plant‐soil system up to 30 cm depth than in tussock grasslands. Our study shows that highland grasslands of central Argentina maintain huge soil C reservoirs. However, livestock use could reduce surface C stocks by affecting the plant biomass compartments, which could have a long‐term effect on soil C stocks. These findings have direct implications for mountain grasslands management and conservation in the context of climate change mitigation.

AbstractThis study aimed to evaluate the influence of large apical preparations with Reciproc (REC), Hyflex CM (HCM) and Twisted File Adaptive (TFA) systems using micro‐computed tomography (MCT). Ninety mesiobuccal (MB) and distobuccal (DB) root canals of maxillary molars (n = 45) were scanned using MCT before and after the shaping procedures. The root canals (n = 15) were prepared until REC 40.06, HCM 40.04 and TFA 35.04. The root canal transportation (RCT), centring ability (CA), change in volume of the root canal and at different levels (VC), remaining dentine thickness (RDT), removal of dentine wall (RDW) and working time (WT) were evaluated. Data were analysed using the Kruskal–Wallis and Dunn tests, and the one‐way ANOVA and Tukey tests with a level of significance set at 5%. No significant difference among the instruments was found regarding the RCT, CA, RDT, RDW and WT (P > 0.05), in larger apical preparations in curved MB and straight DB canals of maxillary molars.

Published: December 2020

AbstractPurposeEffectiveness of ocriplasmin for vitreomacular traction (VMT) varies depending on the presence of common ocular conditions and patient selection criteria. We carried out a systematic literature review and meta‐analysis of ocriplasmin studies conducted in real‐world settings (RWS) and compared outcomes with those from randomized controlled trials (RCTs).MethodsWe included prospective and retrospective studies from RWS documenting effectiveness of ocriplasmin in patients with VMT with or without MH, and RCTs of ocriplasmin versus control. Key end‐points were vitreomacular adhesion resolution (VMAR), nonsurgical MH closure, need for vitrectomy and safety. We conducted meta‐regression on pooled results to evaluate effects of baseline covariates and study design on outcomes.ResultsThirty RWS (2402 patients) and 5 RCTs (737 patients) were included epiretinal membrane (ERM) and broad VMA were more prevalent in RCTs. Primary VMAR, vitrectomy and MH closure rates were comparable between RWS and RCTs. Rates of nsVMAR were significantly higher in RWS than RCTs (odds ratio 1.66; 95% confidence interval [CI]: 1.18–2.34). nsVMAR rates were inversely associated with ERM prevalence (odds ratio 0.20; 95% CI: 0.08–0.51). Compared with the recent OASIS trial, RWS reported a higher incidence of new/worsening subretinal fluid cases and less photophobia, photopsia, vitreous floaters, electroretinogram abnormalities and MH progression.ConclusionsOcriplasmin was significantly more effective in achieving nsVMAR in RWS than in RCTs. Lower ERM prevalence in RWS was the single significant explanatory variable for this difference. Conclusions on ocriplasmin safety in RWS are limited due to inconsistent reporting.
