Robotic transformative service research: deploying social robots for consumer well-being during COVID-19 and beyond
Authors: Henkel Alexander P. , Čaić Martina , Blaurock Marah , Okan Mehmet 
Published: August 2020

PurposeBesides the direct physical health consequences, through social isolation COVID-19 affects a considerably larger share of consumers with deleterious effects for their psychological well-being. Two vulnerable consumer groups are particularly affected: older adults and children. The purpose of the underlying paper is to take a transformative research perspective on how social robots can be deployed for advancing the well-being of these vulnerable consumers and to spur robotic transformative service research (RTSR).Design/methodology/approachThis paper follows a conceptual approach that integrates findings from various domains: service research, social robotics, social psychology and medicine.FindingsTwo key findings advanced in this paper are (1) a typology of robotic transformative service (i.e. entertainer, social enabler, mentor and friend) as a function of consumers' state of social isolation, well-being focus and robot capabilities and (2) a future research agenda for RTSR.Practical implicationsThis paper guides service consumers and providers and robot developers in identifying and developing the most appropriate social robot type for advancing the well-being of vulnerable consumers in social isolation.Originality/valueThis study is the first to integrate social robotics and transformative service research by developing a typology of social robots as a guiding framework for assessing the status quo of transformative robotic service on the basis of which it advances a future research agenda for RTSR. It further complements the underdeveloped body of service research with a focus on eudaimonic consumer well-being.
Family business identity, consumer product evaluations and firm size
Authors: Shen Anyuan , Tikoo Surinder 
Published: August 2020

Purpose
This study aims to examine the relationship between family business identity disclosure by firms and consumer product evaluations and the moderating impact, if any, of firm size on this relationship. Toward this end, the study seeks to develop a theoretical explanation for how consumers process family business identity information.

Design/methodology/approach
A qualitative pre-study was conducted to obtain preliminary evidence that consumers’ perceptions of family businesses originate from both family- and business-based category beliefs. A product evaluation experiment, involving young adult subjects, was used to test the research hypotheses, and the experiment data were analyzed using MANOVA.

Findings
The key finding was that the effect of family business identity disclosure on consumer product evaluations is moderated by firm size.

Practical implications
This research has implications for businesses seeking to promote their family business identity in branding communications.

Originality/value
This research provides a theoretical account of why consumers might hold different perceptions of family business brands. The interactive effect of firm size and family business identity information disclosure on consumer product evaluations contributes new insight to family business branding.
Effectiveness of a brief versus a comprehensive social marketing program
Authors: Durl James , Dietrich Timo , Kubacki Krzysztof 
Published: August 2020

Purpose
Gamified and engaging school-based alcohol social marketing programs have demonstrated effectiveness; however, wide-scale dissemination of these programs is limited by their resource-intensive character. The purpose of this paper is to address this limitation, a brief alcohol social marketing pilot program was derived from a comprehensive alcohol social marketing program to compare effectiveness.

Design/methodology/approach
A sample of 115 14–16-year-old adolescents from six secondary schools participated in the brief alcohol social marketing pilot program. Program effectiveness was assessed using repeated measure analysis on adolescents’ knowledge, attitudes, social norms, self-efficacy and intentions to binge drink. Results were compared with the comprehensive social marketing program and a control group.

Findings
The brief pilot program produced statistically significant outcomes for the same measures as the comprehensive program across attitudinal variables, descriptive norms and opportunistic self-efficacy.

Research limitations/implications
Converting existing social marketing programs into brief alternates is more cost-effective and, in this case, demonstrated better outcome effects. However, findings are limited as in-depth comparisons were hindered by changes to content across program modes. No process for converting comprehensive programs into brief alternates was identified prior to this study, and therefore a number of considerations for program alteration were derived from program facilitator experiences.

Originality/value
The findings provide initial evidence that a brief version of an existing comprehensive program can be an effective alternate to more resource-intensive programs under more cost-effective circumstances for program developers and facilitators.

Authors: Sarkeshikian Ali , Zakery Amir , Shafia Mohammad Ali , Aliahmadi Alireza 
Published: August 2020

PurposeMuch research has been conducted on technology acceptance (TA), which is mainly about the acceptance by one user. As more than one person should be involved in business-to-business TA decision-making, it is suggested that different processes for making a consensus among different stakeholders should be considered. The purpose of this study is to demonstrate a model for essential activities and characteristics of advocators for accelerating the stakeholders’ consensus in the technology acceptance (SCTA).Design/methodology/approachThe conceptual model of this research is presented using a thematic analysis of the interviews with the relevant experts and existing literature. Furthermore, the structural equation model was applied for analyzing empirically how advocators’ characteristics and activities affect consensus. In total, 248 respondents completed the questionnaires. Experts’ opinions, Krippendorff’s alpha index, Cronbach’s alpha coefficient and goodness of fit indices were applied to verify the reliability of the results.FindingsResults show that “being leader” and “being influential” are two main characteristics for the advocators’ team that significantly affect SCTA. Reducing perceived “risk” for each stakeholder, developing a “common understanding” among them and demonstrating “resource readiness” are also the main tasks of advocators leading to SCTA.Originality/valueThe role of advocators in SCTA has been neglected. The main contribution of this study is identifying the required advocators’ activities and characteristics for achieving SCTA.
Ownership structure and auditor selection
Authors: Hall Curtis M. , Hoffman Benjamin W. , Liu Zenghui 
Published: August 2020

PurposeThis paper aims to investigate the effect that ownership structure (public vs private) has on the demand for high-quality auditors, specifically in the US banking industry.Design/methodology/approachThe authors predict that public banks are more likely to hire a high-quality auditor than private banks and pay a higher audit fee premium for that high-quality auditor (due to higher agency costs, more demand for financial information and higher litigation risk). The authors analyze 2008–2014 banking data from the Federal Reserve using probit and OLS regression analysis to examine if there is a higher probability that public banks choose higher quality auditors and pay higher audit fees when they do so.FindingsThe results show that private banks are less likely to hire Big 4 auditors and industry-expert auditors than public banks. The authors also find that both private and public banks pay higher audit fees for Big 4 and industry-expert auditors, and that public banks pay a higher premium for Big 4 auditors and industry experts than private banks.Research limitations/implicationsThe findings may not be fully generalizable to other types of firms, as banking is a heavily regulated and complex industry. However, inferences from this study may be generalizable to other similar industries such as insurance or health care.Practical implicationsThe results of this paper imply that public and private banks have differing priorities when hiring their financial statement auditor. This may be of interest to investors and auditing regulators.Social implicationsThe findings of this paper underscore the value of hiring an industry-expert auditor in an industry that is highly complex and regulated. This may be of interest to managers and policymakers.Originality/valueDue to data restrictions, the emphasis of prior literature on the banking industry has been on public banks. This study is the first to analyze the differences between public and private banks’ demand for audit services.

Published: August 2020

PurposeAlthough several studies have been undertaken on sustainability within infrastructure projects, limited attention has paid to the drivers for, and the barriers to, the incorporation of sustainability in public–private partnership (PPP) infrastructure projects through empirical study, particularly in Nigeria. Therefore, this study aims to identify and examine the drivers that promote sustainability in Nigerian PPP infrastructure projects and assess the barriers to the full integration of sustainability practices into current Nigerian PPP infrastructure projects.Design/methodology/approachPrimary data were collected using a questionnaire survey. The questionnaire survey was targeted on four different stakeholders’ organizations. They were public sector authorities, concessionaires, consultants and banks already undertaking PPP infrastructure projects in Lagos State, Nigeria. The obtained data were analyzed using frequency, percentage, mean score, standard deviation and the Kruskal–Wallis test.FindingsThe study identified 17 drivers that promote the incorporation of sustainability in PPP infrastructure projects. The analysis of the total ranking of the drivers in Nigeria revealed the top five ranked drivers to be: consideration of long-term performance; contractual arrangements; incentives for new market penetration; award criteria; and selection criteria, respectively. The study further identified 11 barriers to sustainability integration in PPP infrastructure projects and the top five ranked barriers in Nigeria are as follows: comprehensive sustainability procurement guidelines; no enabling environment; education needs; uncertain economic environment; and a lack of clear government policy, respectively. The results of the Kruskal–Wallis test conducted on both the 17 identified drivers for, and the 11 barriers to, the incorporation of sustainability in Nigerian PPP infrastructure projects revealed that there is no significant statistical difference in both rankings from the perceptions of the aforementioned four different respondents’ groups.Research limitations/implicationsThe study provides empirical insights on the knowledge and awareness of drivers which could lead to a greater uptake in sustainability measures by the stakeholders in Nigerian PPP projects; it also identified barriers to overcome.Originality/valueThe importance of the incorporation of sustainability in public procurement cannot be over-emphasized. It is anticipated that the study will be of great value to PPP stakeholders involved in sustainability decision-making processes when delivering sustainable PPP projects.

AbstractNivolumab plus ipilimumab combination is currently one of the preferred regimens for advanced melanoma in recently updated clinical practice guidelines. However, the evidence on the efficacy of the combination for acral or mucosal subtypes remains less robust. This is the final analysis of a multicenter, open‐label, uncontrolled phase II study that investigated the long‐term efficacy and safety in treatment‐naive Japanese patients with advanced melanoma, including acral or mucosal subtypes, and subsequent therapy after discontinuation of the investigational agents. Patients received four doses of nivolumab (1 mg/kg i.v.) in combination with ipilimumab (3 mg/kg i.v.) at 3‐week intervals, followed by doses of nivolumab (3 mg/kg i.v.) at 2‐week intervals. The median follow‐up period was 20.8 months (range, 5.2–35.0). The centrally and locally assessed objective response rates were both 43.3% (13/30; 95% confidence interval [CI], 25.5–62.6). Median progression‐free survival was not reached (95% CI, 3.02–not reached), and median overall survival was also not reached (95% CI, 19.52–not reached). The 30‐month progression‐free survival and overall survival rates were 50.3% and 54.2%, respectively. No new safety concerns were detected. After discontinuation of the investigational agents, 83.3% of patients received some form of subsequent therapy including 43.3% of patients who received nivolumab monotherapy and 26.7% of patients who received radiotherapy. Of the four patients who discontinued the investigational agents because of immune‐related adverse events, two received subsequent therapy (nivolumab and ipilimumab, respectively) and the other two showed long‐term treatment‐free survival (659 and 590 days, respectively). Long‐term survival with nivolumab plus ipilimumab was observed in Japanese patients with melanoma including acral and mucosal subtypes, which is consistent with the CheckMate 067 study. Many patients continued to receive some form of treatment safely after stopping treatment with nivolumab plus ipilimumab.

AbstractMicrobiota live in a closely regulated interaction with their environment, and vice versa. The presence and absence of microbial entities is greatly influenced by features of the niche in which they thrive. Characteristic of this phenomenon is that different human skin sites harbor niche‐specific communities of microbes. Microbial diversity is considerable, and the current challenge lies in determining which microbes and (corresponding) functionality are of importance to a given ecological niche. Furthermore, as there is increasing evidence of microbial involvement in health and disease, the need arises to fundamentally understand microbiome processes for application in health care, nutrition and personal care products (e.g. diet, cosmetics, probiotics). This review provides a current overview of state‐of‐the‐art sequencing‐based techniques and corresponding data analysis methodology for profiling of complex microbial communities. Furthermore, we also summarize the existing knowledge regarding cutaneous microbiota and their human host for a wide range of skin diseases.
National Food Consumption Patterns: Converging Trends and the Implications for Health
Authors: Le Thai H. , Disegna Marta , Lloyd Tim 
Published: August 2020

SummaryWorldwide, obesity almost tripled between 1975 and 2016 and is now prevalent in both rich and poor countries. Using annual food availability data produced by the Food and Agriculture Organisation of the United Nations (FAO) covering half a century in 118 countries, this article explores the diets that are central to the problem of obesity, identifying groups of countries with similar consumption patterns. Applying algorithms from the fuzzy clustering literature, five distinct consumption patterns are revealed whose dietary composition broadly corresponds to diets that we label ‘Western’, ‘Traditional’, ‘Mediterranean’, ‘Tropical’ and ‘Vegetarian’. Despite differences in dietary characteristics, all five share two common themes: rising total calories and declining healthiness, both of which are linked to the substitution of plant‐based foods with food derived from animals. That the evidence points to a convergence on the ‘Western’ diet, the most obesogenic and least healthy of all the diets we consider, is a cause for concern. The key message is that in a future where people are predicted to live longer – but not necessarily healthier – lives, recent efforts to address the challenge are prescient, and as the results in the article imply, need to be heeded globally.

Published: August 2020

AbstractQuality protein maize (QPM) is a biofortified maize rich in lysine and tryptophan, essential amino acids required in human nutrition. This research therefore characterizes native and modified starches from QPM by evaluating the physicochemical properties, Fourier transform infrared spectra (FTIR), and pasting properties. The native QPM starch was modified by oxidation, acetylation, pregelatinization, and acid thinning techniques. The starch yield of native QPM was 43.80%, while that of modified starches were from 88.22 to 98.34%. The moisture content of the native and modified starches was from 4.56 to 9.20 g/100g. Modifications significantly (P ≤ 0.05) reduced the lipid, protein, and amylose contents of the QPM. While the native starch had 0.72 g/cm3 bulk density, modified starches were between 0.59 and 0.88 g/cm3; chemical modification reduced the bulk density and physical modification increased it. In addition, all the modifications except oxidation significantly (P ≤ 0.05) increased water absorption capacity. The oil absorption of the starch samples was increased by modification techniques used with the exception of physical modification. Chemical modification reduced the viscosity of QPM starch while physical modification increased it. The reducing sugar content of the starch was reduced by both the physical and chemical starch modification techniques. Acetylated sample exhibited the highest swelling power while acid‐thinned sample had the least. The major functional groups identified via FTIR were OH, C‐H, C=H, and C≡H. Modifications did not affect the functional groups as all the native and modified starches (except oxidized sample) all have similar spectrum and bands stretch.Practical ApplicationThe study contributes to existing knowledge on valorization of modified starch from quality protein maize. Profiling the chemical attributes of modified starches is especially valuable in novel food processing techniques.

SummaryAedes albopictus transmits several arboviral infections. In the absence of vaccines, control of mosquito populations is the only strategy to prevent vector‐borne diseases. As part of the search for novel, biological and environmentally friendly strategies for vector control, the isolation of new bacterial species with mosquitocidal activity represents a promising approach. However, new bacterial isolates may be difficult to grow and genetically manipulate. To overcome these limits, here we set up a system allowing the expression of mosquitocidal bacterial toxins in the well‐known genetic background of Bacillus subtilis. As a proof of this concept, the ability of B. subtilis to express individual or combinations of toxins of Bacillus thuringiensis israelensis (Bti) was studied. Different expression systems in which toxin gene expression was driven by IPTG‐inducible, auto‐inducible or toxin gene‐specific promoters were developed. The larvicidal activity of the resulting B. subtilis strains against second‐instar Ae. albopictus larvae allowed studying the activity of individual toxins or the synergistic interaction among Cry and Cyt toxins. The expression systems here presented lay the foundation for a better improved system to be used in the future to characterize the larvicidal activity of toxin genes from new environmental isolates.
Anti‐cyclic citrullinated peptide but not rheumatoid factor is associated with ultrasound‐detected bone erosion among rheumatoid arthritis patients with at least moderate disease activity

Published: August 2020

AbstractAimTo investigate anti‐cyclic citrullinated peptide (anti‐CCP) and rheumatoid factor (RF) in relation to ultrasound‐detected joint inflammation and bone erosion in patients with rheumatoid arthritis (RA) as previous studies have mainly utilized radiographic damage as imaging outcomes.MethodIn this cross‐sectional study, patients were grouped based on their Disease Activity Score at 28 joints (DAS28 < 3.2, DAS28 ≥ 3.2). Ultrasound variables (power Doppler and gray scale joint inflammation graded 0‐3 semi‐quantitatively; bone erosion graded Yes = 1/No = 0 dichotomously) were correlated with antibodies levels using Pearson correlation. Simple linear regression was used to characterize relationships between variables. Receiver operating characteristic (ROC) analysis was performed to determine statistically optimal cut‐off values for identifying patient subgroups with ultrasound erosion scores >25th, >50th and >75th percentiles.ResultsOne thousand and eighty joints and 1800 joint recesses from 36 peripheral joint sites were scanned in 30 adult RA patients (mean disease duration, 70.3 months; 93.3% female; 93.3% anti‐CCP positive; 93.3% RF positive). In the DAS28 < 3.2 group, no significant correlations were found between antibody levels and ultrasound variables. In the DAS28 ≥ 3.2 group, anti‐CCP levels correlated significantly (r = 0.46, P = .048) and were predictive (P = .048) of ultrasound erosion scores. Area under the ROC curve based on cut‐off anti‐CCP level of ≥95.2 to identify patients with ultrasound erosion scores >7 (75th percentile) was 0.72 (sensitivity = 83.3%, specificity = 53.8%).ConclusionThe association of anti‐CCP and RF with joint damage appears to differ in RA. Among patients with at least moderate disease activity (DAS28 ≥ 3.2), anti‐CCP—but not RF—is associated with joint damage, being moderately correlated with ultrasound‐detected bone erosion.
