Complaint behaviour in multichannel retailing: a cross-stage approach
Authors: Frasquet Marta , Ieva Marco , Ziliani Cristina 
Published: June 2021

PurposeThis paper analyses how the purchase channel and customer complaint goals affect the sequential choice of post–purchase complaint channels when customers experience a service failure followed by a service recovery failure (double deviation).Design/methodology/approachAn online survey involving a scenario manipulation was conducted with 577 apparel shoppers. The study employs multi-group latent class analysis to estimate latent customer segments within both online and offline groups of shoppers and compare latent classes between the two groups.FindingsThe results show that the purchase channel has a lock-in effect on the complaint channel, which is stronger for offline buyers. Moreover, there is evidence of channel synergy effects in the case of having to complain twice: shoppers who complain in store in the first attempt turn to online channels in the second complaint attempt, and vice versa. Complaint goals shape the choice of complaint channels and define different shopper segments.Originality/valueThe present study is the first to adopt a cross-stage approach that analyses the dependencies between the purchase channel and the complaint channel used on two subsequent occasions: the first complaint after a service failure and the second following a service recovery failure.
Improving novelty detection by self-supervised learning and channel attention mechanism
Authors: Tian Miao , Cui Ying , Long Haixia , Li Junxia 
Published: June 2021

Purpose
In novelty detection, the autoencoder based image reconstruction strategy is one of the mainstream solutions. The basic idea is that once the autoencoder is trained on normal data, it has a low reconstruction error on normal data. However, when faced with complex natural images, the conventional pixel-level reconstruction becomes poor and does not show the promising results. This paper aims to provide a new method for improving the performance of novelty detection based autoencoder.

Design/methodology/approach
To solve the problem that conventional pixel-level reconstruction cannot effectively extract the global semantic information of the image, a novel model with the combination of attention mechanism and self-supervised learning method is proposed. First, an auxiliary task, reconstruct rotated image, is set to enable the network to learn global semantic feature information. Then, the channel attention mechanism is introduced to perform adaptive feature refinement on the intermediate feature map to optimize the correspondingly passed feature map.

Findings
Experimental results on three public data sets show that the proposed method has potential performance for novelty detection.

Originality/value
This study explores the ability of self-supervised learning methods and attention mechanism to extract features on a single class of images. In this way, the performance of novelty detection can be improved.
Exploring the influence of channel leadership style on channel commitment in a franchising context
Authors: Sharma Dheeraj , Patel Shivan Sanjay , Pandey Shivendra Kumar 
Published: June 2021

Purpose
This paper aims to explore franchisor–franchisee relationships in the context of plural forms. Plural forms implies the co-existence of franchised and non-franchised outlets of a given company. More specifically, the paper examines the impact of franchisors’ leadership styles on franchisees’ relationship commitment when the company franchised outlets co-exist with independent non-franchised outlets. Specifically, this study operationalize the plural forms phenomenon in franchising, using multi-channel complexity as a moderator. The mediating role of relational capital is also examined.

Design/methodology/approach
Data were collected from 254 franchisees. The hypothesized model was tested using partial least squares structural equation modeling (PLS-SEM).

Findings
The results indicate that all three – participative, supportive and directive leadership styles of franchisors increase relationship commitment. In a high channel complexity context, a supportive leadership style is the most effective, whereas, in a low channel complexity context, a participative style is the most effective. Relational capital also partially mediated the relationships between leadership styles and relationship commitment.

Practical implications
Franchisors should follow a participative leadership style when channel complexity is low. However, as they add new channels and the channel complexity increases, franchisors should shift toward a supportive leadership style to maintain existing franchisees’ commitment. In current environments, managers should avoid using directive leadership in favor of the other two leadership styles.

Originality/value
The present study is the first to examine the influence of channel leadership style on relationship commitment in an environment of multiple channel complexity.
Putting marketing knowledge to use: marketing-specific relational capital and product/service innovation performance
Authors: Peñalba-Aguirrezabalaga Carmela , Ritala Paavo , Sáenz Josune 
Published: June 2021

PurposeThe importance of integrating both internal and external knowledge into the product/service innovation process has been widely recognized in the knowledge management and innovation literature. Likewise, the role of the marketing and sales function as a driver of innovation has been stressed because of its market-facing role. However, limited research has investigated the complementarity of both internal and external knowledge regarding product/service innovation performance in a marketing context. The purpose of this study is to analyze marketing departments’ role in accessing internal and external knowledge resources (i.e. marketing-specific relational capital [RC]) to reach improved product and service innovation performance.Design/methodology/approachThe analysis uses empirical evidence collected by a structured survey of 346 respondents representing marketing and sales functions in Spanish companies.FindingsThe survey revealed that marketing-specific internal relational capital at the department and inter-department levels, as well as noncustomer external RC, are directly associated with product/service innovation performance. Further, the analyses show that the relationship between customer-specific RC and innovation performance is mediated by other types of RC, making it a fundamental antecedent to the innovation process. Finally, significant differences in marketing-specific RC subcomponents were found between business-to-consumer (B2C) and business-to-business (B2B) firms.Originality/valueThis study makes a valuable contribution to marketing and management literature by revealing the types of social interactions in the marketing function that enable access to knowledge sources that promote successful product/service innovation.
Higher accounting education curriculum development: evidence from Tunisia
Authors: Khemiri Rim , Dammak Mariam 
Published: June 2021

Purpose
This paper aims to trace the process of setting up and developing the higher accounting education curriculum in Tunisian public institutions, stressing the period 1956–1981. Further, this study intends to highlight specificities of the Tunisian context during this period, focusing on the main roles of the Tunisian State and some key actors.

Design/methodology/approach
This study is based on a historical approach. Two complementary methodologies were used, mainly, documentary study and semi-directive interviews with key actors heavily involved in higher education. The critical accounting framework and Foucault’s power-knowledge relationship were mobilized to this end.

Findings
The paper provides a general overview of higher accounting education in the Tunisian context, focusing on three specific periods. First, in the post-independence period (1956–1960), higher accounting education was a very underdeveloped French heritage. Second, during the 1960s, the Tunisian State focused on institutional and structural measures to set up the initial foundation. Those measures were impacted by the Tunisian socialist economic system, the development of capital human and the cultural French influence, at once. Third, the 1970s were essentially marked by the role of university-scholars and professional-accountants to set up a higher accounting curriculum. The market-oriented economy and the higher social equity are assumed to influence the above-mentioned setting-up. The culmination of this extending process was the unification and publication of the first official program of accounting studies, at the start of 1981.

Originality/value
To the best of the authors’ knowledge, this study is the first attempt to trace the process of setting up and developing of higher accounting education curriculum in Tunisia. This study contributes to a better understanding of this process, shedding some light on the specificities of the Tunisian context during the period 1956 to 1981.
Shipping managers’ information behavior during a pandemic crisis
Authors: Gerakoudi-Ventouri Kelly 
Published: June 2021

PurposeA significant body of literature suggests that shipping companies operate in an extremely volatile and risky environment, relying on the effective use of information to remain competitive. However, decision-making in this market is demanding because of the high uncertainty, market competition and significant capital investments. Moreover, the rapid spread of COVID-19 renders information uncertainty a daunting challenge for companies engaged in global trade. Hence, this study aims to explore the information behavior of managers in a time of crisis seems compelling.Design/methodology/approachThis study provides novel insights into the information behavior of senior managers by adopting a qualitative approach. Forty-nine semi-structured face-to-face interviews with individuals from Hellenic shipping companies were conducted. Moreover, this study explores the extant theory qualitatively, using the grounded theory methodology and shows that an unprecedented event (pandemic crisis) can redefine the information behavior of managers.FindingsThis study highlights the importance of information in decision-making. Moreover, the results show that, during a pandemic, managers resort to alternative information sources, adopt collaborative information behaviors and take advantage of digital technology.Originality/valueThere is limited research in exploring the information behavior of managers in times of pandemics. This research underscores the fact that during a crisis, managers seek information from digital information resources and decision-making assumes a more decentralized form. This study concludes with a discussion of the theoretical and practical implications of these findings.
The impact of workplace loneliness on employee outcomes: what role does psychological capital play?
Authors: Firoz Mantasha , Chaudhary Richa 
Published: June 2021

PurposeWith little empirical attention devoted to the consequences of loneliness in the workplace, the present study investigated the effect of workplace loneliness on creative performance, organizational citizenship behaviors and work-family family conflict. Furthermore, psychological capital was examined as a moderator of these relationships.Design/methodology/approachThe proposed model was tested in two different studies on a sample of employees from manufacturing (Sample 1:n = 379) and service (Sample 2:n = 559) organizations in India. Data were collected using self-administered questionnaires at two different points in time. Confirmatory factor analysis and multiple hierarchical regressions were used to test the hypothesized model.FindingsWhile workplace loneliness was found to negatively affect creative performance and organizational citizenship behavior, its impact on work-family conflict was positive. Results revealed a significant moderating effect of psychological capital on these relationships. Psychological capital buffered the impact of loneliness in a way that the detrimental effect of loneliness on performance behaviors was less severe for the individuals with high psychological capital.Originality/valueThe study makes an original and noteworthy contribution to the loneliness and negative emotions literature by advancing the understanding around the consequences and boundary conditions of loneliness in the workplace. It carries important implications for managing loneliness in the organizations by identifying psychological capital as an important personal resource for mitigating the effects of workplace loneliness on creativity and extra-role behaviors.

Published: June 2021

ObjectiveThis study investigated the cost‐effectiveness of a community‐based colorectal cancer‐screening program (C‐CRCSP) in Shanghai, China, among the residents in the urban, suburban and rural areas.MethodsA Markov model was constructed to evaluate the cost‐effectiveness of a 25‐year annual C‐CRCSP including 100 000 populations. Cost‐effectiveness was determined by the incremental cost‐effectiveness ratio (ICER); referring to either life‐years gained, or quality‐adjusted life‐years (QALYs) gained. The threshold was gross domestic product per capita. Univariate and multivariate sensitivity analyses were performed to investigate the influence of compliance, prevalence, technological performance, medical cost and annual cost discount rate (3.5%) on ICER. A probabilistic sensitivity analysis evaluated the probability of the cost‐effectiveness of C‐CRCSP at different maximum acceptable ceiling ratios.ResultsCompared with no screening, the C‐CRCSP resulted in total gains of 7840 QALYs and 2210 life‐years (LY), at a total cost of CNY 58.54 million; that is, the ICER were CNY 7460/QALYs and CNY 26650/LY. Stratifying by residency, the cumulative gains in QALYs and LY were estimated to be the lowest in the urban populations compared with the rural and suburban populations. The cost for the urban population was 3‐fold and 6‐fold that of the suburban and rural populations. The ICER for QALYs ranged from 2180 (rural) to 16 840 (urban).ConclusionThe cost‐effectiveness of a C‐CRCSP in Shanghai was most favorable for the rural population, while the urban population benefits less in terms of QALYs. ICER could be enhanced by measures that increase compliance.
Bioproduction of L‐piperazic acid in gram scale using Aureobasidium melanogenum

Published: June 2021

SummaryCurrently, piperazic acid is chemically synthesized using ecologically unfriendly processes. Microbial synthesis from glucose is an attractive alternative to chemical synthesis. In this study, we report the production of L‐piperazic acid via microbial fermentation with the first engineered fungal strain of Aureobasidium melanogenum; this strain was constructed by chassis development, genetic element reconstitution and optimization, synthetic rewiring and constitutive genetic circuit reconstitution, to build a robust L‐piperazic acid synthetic cascade. These genetic modifications enable A. melanogenum to directly convert glucose to L‐piperazic acid without relying on the use of either chemically synthesized precursors or harsh conditions. This bio‐based process overcomes the shortcomings of the conventional synthesis routes. The ultimately engineered strain is a very high‐efficient cell factory that can excrete 1.12 ± 0.05 g l‐1 of L‐piperazic acid after a 120‐h 10.0‐l fed‐batch fermentation; this is the highest titre of L‐piperazic acid reported using a microbial cell factory.
Performance measurement systems and client performance in fee‐generating not‐for‐profit human service organisations
Authors: Harrison Graeme , Jiao Lu , Chen Jinhua 
Published: June 2021

AbstractWe use survey and archival data from 271 fee‐generating not‐for‐profit human service organisations in Australia to examine how the use of performance measurement systems affects those organisations’ client performance. Using Simons’ levers of control, we find that interactive and diagnostic uses of performance measurement systems are positively related to client performance. We also find beliefs control to positively moderate the relation between diagnostic use of performance measurement systems and client performance, and boundary control to negatively moderate the relation between interactive use of performance measurement systems and client performance. The findings have implications for research and practice.

Published: June 2021

AbstractBackgroundThe NovoSorb® Biodegradable Temporising Matrix (BTM) is a synthetic polyurethane dermal matrix used to reconstruct complex wounds including deep dermal and full‐thickness burns, necrotising fasciitis and free flap donor site. We hope to further explore its potential applications in this series.MethodsPatients who received BTM application across four centres over an 18‐month period were included. Patients were followed up to assess BTM and graft take, the aesthetic, the return of sensation and complications.ResultsA total of 27 patients with 35 wounds were identified with a range of aetiologies. Thirty‐three wounds had 100% integration of BTM at the time of sealing membrane removal. Seven wounds had partial graft loss that later healed by secondary intention. In two cases, re‐epithelialisation occurred with BTM alone without split‐skin graft.ConclusionBTM offers a safe and reliable reconstructive option in challenging wounds that would otherwise require more complex operations.
Estimating mean potential outcome under adaptive treatment length strategies in continuous time
Authors: Sun Hao , Ertefaie Ashkan , Johnson Brent A. 
Published: June 2021

AbstractAn adaptive treatment length strategy is a sequential stage‐wise treatment strategy where a subject's treatment begins at baseline and one chooses to stop or continue treatment at each stage provided the subject has been continuously treated. The effects of treatment are assumed to be cumulative and, therefore, the effect of treatment length on clinical endpoint, measured at the end of the study, is of primary scientific interest. At the same time, adverse treatment‐terminating events may occur during the course of treatment that require treatment be stopped immediately. Because the presence of a treatment‐terminating event may be strongly associated with the study outcome, the treatment‐terminating event is informative. In observational studies, decisions to stop or continue treatment depend on covariate history that confounds the relationship between treatment length on outcome. We propose a new risk‐set weighted estimator of the mean potential outcome under the condition that time‐dependent covariates update at a set of common landmarks. We show that our proposed estimator is asymptotically linear given mild assumptions and correctly specified working models. Specifically, we study the theoretical properties of our estimator when the nuisance parameters are modeled using either parametric or semiparametric methods. The finite sample performance and theoretical results of the proposed estimator are evaluated through simulation studies and demonstrated by application to the Enhanced Suppression of the Platelet Receptor IIb/IIIa with Integrilin Therapy (ESPRIT) infusion trial data.

Published: June 2021

AbstractBackgroundA peripheral blood eosinophilia of greater than 1.0 × 109/L is relatively unusual and offers a clue to the underlying diagnosis. In 2003, we established a specialist service to diagnose unexplained eosinophilia.ObjectiveTo describe the causes of an eosinophilia in our service and the diagnostic algorithm we developed.MethodsSubjects were referred by physician colleagues across a range of specialties and undertook standard investigations following a semi‐structured protocol. Data were extracted from a bespoke database.ResultsThree hundred and eighty two subjects were referred over a 17‐year period. Average age was 54 years and 183 (48%) of subjects were female, with 21 of 25 (84%) females in the idiopathic eosinophilic pneumonia group (p < 0001), 22 of 30 (73%) females in the gastrointestinal disease group (p < .008), but 11 of 37 (30%) females in the eosinophilic granulomatosis with polyangiitis group (p < .04). A diagnosis was assigned after systematic evaluation using a pre‐defined algorithm in 361 (94.5%) of cases. Fungal allergy (82 subjects: 21%), parasitic infection (61 subjects: 16%) and severe eosinophilic asthma (50 subjects: 13%) were the three commonest individual diagnoses. Hypereosinophilic syndrome (HES) disease including eosinophilic granulomatosis with polyangiitis (EGPA) accounted for 85 subjects (20%) of which seven subjects (2%) had myeloproliferative disease (M‐HES). A high IgE was common, and 79 (91%) of subjects with complete data who had an IgE of ≥1000 IU/L had fungal allergy or parasite infection. The serum tryptase was raised in 44 of 302 (14.5%) of individuals across all diagnostic groups, though none had mastocytosis.ConclusionA diagnosis of an unexplained eosinophilia can usually be determined using as semi‐structured algorithm. Parasitic infection and fungal allergy often with severe eosinophilic asthma were common causes, whereas HES, particularly myeloproliferative, disease was relatively rare.
Towards a Neural Graphics Pipeline for Controllable Image Generation
Authors: Chen Xuelin , Cohen‐Or Daniel , Chen Baoquan , Mitra Niloy J. 
Published: June 2021

AbstractIn this paper, we leverage advances in neural networks towards forming a neural rendering for controllable image generation, and thereby bypassing the need for detailed modeling in conventional graphics pipeline. To this end, we present Neural Graphics Pipeline (NGP), a hybrid generative model that brings together neural and traditional image formation models. NGP decomposes the image into a set of interpretable appearance feature maps, uncovering direct control handles for controllable image generation. To form an image, NGP generates coarse 3D models that are fed into neural rendering modules to produce view‐specific interpretable 2D maps, which are then composited into the final output image using a traditional image formation model. Our approach offers control over image generation by providing direct handles controlling illumination and camera parameters, in addition to control over shape and appearance variations. The key challenge is to learn these controls through unsupervised training that links generated coarse 3D models with unpaired real images via neural and traditional (e.g., Blinn‐Phong) rendering functions, without establishing an explicit correspondence between them. We demonstrate the effectiveness of our approach on controllable image generation of single‐object scenes. We evaluate our hybrid modeling framework, compare with neural‐only generation methods (namely, DCGAN, LSGAN, WGAN‐GP, VON, and SRNs), report improvement in FID scores against real images, and demonstrate that NGP supports direct controls common in traditional forward rendering.
