Robot-assisted 3D digital reconstruction of heritage artifacts: area similarity approach
Authors: Gothandaraman Rajkumar , Muthuswamy Sreekumar 
Published: May 2020

PurposeThis paper aims to propose a system to acquire images automatically for digital reconstruction of heritage artifacts using a six-degree of freedom industrial manipulator.Design/methodology/approachA virtual environment is created using Robot Studio® software to integrate the trajectory and differential motion of the robot manipulator and the motion of camera while acquiring images. A new area similarity matrix method is proposed to reduce the number of images required for digital reconstruction using Autodesk Recap® software. Real-time experiments have been performed using objects such as minion, ultimaker robot and cube. Evaluation of the digital reconstruction is conducted using the contour area matching method.FindingsThe number of images required for reconstruction based on area similarity matrix method is reduced to 63 per cent when compared with the random selection method. Quality parameters such as surface area, volume, number of defect holes, vertices and faces are enhanced for the proposed method.Research limitations/implicationsDigital reconstruction of large-sized heritage artifacts cannot be performed in this setup. But this can be overcome by fixing the manipulator on a mobile platform or overhead crane. This paper does not discuss the reconstruction of partially damaged heritage artifacts, which could be accomplished based on deep learning techniques.Practical implicationsUsing this approach, off-the-shelf heritage artifacts and large-scale objects can be reconstructed digitally with a minimum number of images and without compromising the quality of original models.Originality/valueTo the best of the authors’ knowledge, area similarity-based approach in 3D digital reconstruction by coupling the kinematics of an industrial manipulator and camera is proposed for the first time. A fully automated digital reconstruction technology to preserve valuable heritage artifacts has been developed. It also highlights the space constraints of the industrial manipulator in digital reconstruction.
Workspace analysis of Cartesian robot system for kiwifruit harvesting
Authors: Au ChiKit , Barnett Joshua , Lim Shen Hin , Duke Mike 
Published: May 2020

Purpose
This paper aims to investigate if a Cartesian robot system for kiwifruit harvesting works more effectively and efficiently than an articulated robot system. The robot is a key component in agricultural automation. For instance, multiple robot arm system has been developed for kiwifruit harvesting recently because of the significant labor shortage issue. The industrial robots for factory automation usually have articulated configuration which is suitable for the tasks in the manufacturing and production environment. However, this articulated configuration may not fit for agricultural application due to the large outdoor environment.

Design/methodology/approach
The kiwifruit harvesting tasks are completed step by step so that the robot workspace covers the canopy completely. A two-arm, Cartesian kiwifruit harvesting robot system and several field experiments are developed for the investigation. The harvest cycle time of the Cartesian robot system is compared to that of an articulated robot system. The difference is analyzed based on the workspace geometries of these two robot configurations.

Findings
It is found that the kiwifruit harvesting productivity is increased by using a multiple robot system with Cartesian configuration owing to its regular workspace geometry.

Originality/value
An articulated robot is a common configuration for manufacturing because of its simple structure and the relatively static factory environment. Most of the agricultural robotics research studies use single articulated robot for their implementation. This paper pinpoints how the workspace of a multiple robot system affects the harvest cycle time for kiwifruit harvesting in a pergola style kiwifruit orchard.
Corruption in interaction: the role of social capital in private–public relationships
Authors: Bondeli Julia V. , Havenvid Malena I. , Solli-Sæther Hans 
Published: May 2020

PurposeThis paper aims to explore corrupt exchange as a type of socioeconomic interaction in private–public relationships and its effects on material flow in connected private-private relationships.Design/methodology/approachThe paper is based on a case study of a private–public network of an import firm in Russia. It focusses on corrupt exchange in routine interactions between the firm’s managers and officials in three regulatory authorities.FindingsThe study reveals how different types of corrupt exchange between firm managers, officials and intermediaries serve as a problem-solving tool that facilitates material flow through bureaucratic gates.Research limitations/implicationsThe paper contributes to the industrial marketing and purchasing research by showing how the social capital concept is useful for explicating mechanisms of socioeconomic interaction in business networks and how the interaction context conditions actors’ roles and interdependencies.Practical implicationsThe paper raises practitioners’ awareness of corrupt exchange in business networks and enables them to anticipate and manage upcoming challenges in bureaucratic procedures.Social implicationsThe study shows how networks’ non-transparent and manipulative tendencies may provide favourable conditions for corruption in the business landscape.Originality/valueThe study provides a unique empirical insight into the socioeconomic mechanisms of corrupt exchange in business networks. It contributes theoretically by conceptualising corrupt officials as taking on the role of quasi-business actors in the personal possession of administrative authority as a resource and by using a novel conceptualisation of social capital to study private–public interaction in business networks.
Constructing a partially formalized general theory of the marketing system: insights from the history of marketing thought
Authors: Shaw Eric H. 
Published: May 2020

Purpose
The purpose of this paper is to construct a general theory of the marketing system that addresses the fundamental question: why do marketing systems occur, survive and grow?

Design/methodology/approach
The approach integrates the concepts and constructs contained in special and mid-range theories, scattered throughout the history of marketing thought, into a logically coherent set of propositions (including definitions, axioms, theorems, scientific laws, bridge laws and hypotheses) that comprise a general theory of the marketing system.

Findings
The theoretical answer to why marketing systems arise, survive and grow is because marketing systems offer the most efficient mechanism for supplying products and services that people demand, thereby increasing economic growth, compared to the opportunity costs of alternative methods of acquisition. Based on just two (of several) marketing efficiency theorems, if the input costs of trading decline (law of reduced transaction costs) and/or the output value increases (law of bulk transactions), then marketing system efficiency rises. This creates an upward spiraling cycle: increasing the extent of the market (law of market size), proliferating opportunities for increasing aggregate production efficiency (through the law of comparative advantage and the law of division of labor), thereby further proliferating opportunities for aggregate marketing system efficiency (e.g. law of central markets, law of marketing specialists), thus fueling further aggregate economic growth (until limited by the law of diminishing returns, the law of the minimum resource or the law of market size). An empirically testable central hypothesis is derived from the propositions: increasing aggregate marketing system efficiency provides both the necessary and sufficient conditions for increasing aggregate economic growth in a society.

Originality/value
The value of developing a general theory of the marketing system is to advance the marketing discipline as a social science. Additionally, a general theory is likely to enhance academic thinking, improve business practice and facilitate interaction among academicians and practitioners. Further, a general theory could also reduce disciplinary fragmentation, avoid identity confusion and lessen the credibility crisis in marketing, among others.
The effects of subjective norm and knowledge about riba on intention to use e-money in Indonesia
Authors: Aji Hendy Mustiko , Berakon Izra , Riza Alex Fahrur 
Published: May 2020

Purpose
Prior studies in the context of electronic money have examined the effect of social pressure [subjective norm (SN)] on usage intention, but the results are found inconclusive. Individual factor is said to be one of the reasons. Therefore, this study aims to propose knowledge about riba (KR) as the individual factor that might explain the inconsistent previous findings.

Design/methodology/approach
A total of 253 responses are collected using online questionnaire. The data are examined by using structural equation modeling (SEM). The interaction moderation technique is used to investigate the moderating role of KR on intention to use e-money.

Findings
The results show that SN significantly influences customers’ perceived usefulness (PU), ease of use (PEU) and intention to use e-money (INT). PU is also proven as a direct predictor of INT. On the contrary, PEU does not significantly influence customer INT, providing support for the indirect effect of hypotheses between PEU–PU–INT. Furthermore, KR is found moderate in the link between PU and INT. Interestingly, the moderating effect of KR does not exist in the relationship from SN and PEU to INT.

Research limitations/implications
This study has a limitation in terms of the samples that are mainly dominated by students. Students’ perception might be different from practitioners’.

Practical implications
The results indicated that Indonesian customers are getting aware and knowledgeable about riba. It weakens the effect of PU on INT. SN as a social factor has also a strong effect on INT. As a practical implication, this paper suggests the government to develop and regulate a more Sharia-compliant business model for e-money. The public must be well informed and also well educated. The socialization and education must be included in any Muslim communities. In addition, given the fact that the chip-based e-money products in Indonesia are owned by conventional banks, it is going to be a wise idea if the government can partner up with the Islamic banks to design and develop the Sharia-compliant e-money.

Originality/value
This paper contributes to the electronic money and internet banking literature by considering Islamic principle factor, that is the rise of public KR. This paper show that inconclusive previous findings might be depended on the public KR.

Consumers' guilt mitigation vis-à-vis discomfort with ambiguity
Authors: Sett Rahul Kumar 
Published: May 2020

PurposeThe purpose of this paper is to empirically establish the boundary conditions of the guilt mitigation process that consumers resort to in justifying consumption under contextual ambiguity, with respect to consumers' discomfit with ambiguity. While well observed, the process of guilt mitigation is less articulated with respect to contextually relevant consumers’ personality trait(s) (such as, discomfort with ambiguity) that may affect decision-making idiosyncratically. This gap is addressed herewith.Design/methodology/approachThree experiments were conducted across two studies to establish the boundary conditions of guilt mitigation in the specific context of transactions involving trade-ins. In doing so, consumers' direct price imputation or, indirectly, their relative preference for financially equivalent, but structurally distinct, price structures was measured. Guilt was induced among consumers by directly manipulating consumers' degree of attachment with their old product (the trade-in).FindingsResults indicate that consumers resort to guilt mitigation in justifying consumption more extensively when they harbor higher levels of discomfort with ambiguity, not otherwise – the moderating effects of consumers' discomfort with ambiguity or the boundary condition under study.Research limitations/implicationsHypothetical buying scenarios, albeit constructed based on field information and subsequently tested for realism, were used to conduct the experiments, versus field experiments using real consumers. Further, the respondent pool comprised of Indian nationals only. These remain the primary limitations of this research.Practical implicationsThe findings indicate that managers may be able to construe deals in a manner that promotes self-segmentation by consumers, especially when consumers harbor greater discomfort with ambiguity. This, in turn, implies reduction in consumer heterogeneity and a concomitant increase in marketing efficiency.Originality/valueBy considering consumers' discomfort with ambiguity in this research, the efficacy of the guilt mitigation process was established with respect to a contextually relevant individual difference factor. While the fundamentally constructive nature of guilt mitigation necessitates such considerations, this research gap, thus addressed, remained unaddressed hitherto.
What generic strategies do private fitness centres implement and what are their impacts on financial performance?
Authors: Vieira Elsa , Ferreira João 
Published: May 2020

PurposeThe purpose of this paper is to identify the strategies that private fitness centres implement and to evaluate their impact on financial performance.Design/methodology/approachBased upon a sample of 151 private fitness centres in Portugal, multivariate statistics report the implemented strategies and their effect on financial performance. We applied exploratory factorial analysis as our methodology to identify the types of strategy and the ANOVA in order to verify if there are differences of financial performance in the strategies.FindingsThe results obtained demonstrate how private fitness centres implement different strategies, including: cost leadership, differentiation, focus, quality of service, combined and stuck in the middle approaches. The relationship between strategies and financial performance, private fitness centres adopting a cost leadership strategy obtain the best financial performance levels in terms of the sales variable relative to any other strategy but with the combined strategy returning a better performance in terms of the return on assets when compared with the cost leadership strategy.Originality/valueThe originality of this paper stems from its identification of the strategies implemented by private fitness centres, thus, just what type of strategies are in effect across the fitness industry: leadership through cost, differentiation or a focused strategy. However, in addition to ascertaining just which strategies undergo implementation, it is also pertinent in determining just which strategy drives the best financial performance for private fitness centres given that private centres may only remain in the market when achieving financial sustainability. Therefore, this paper seeks to provide information for managers as regards the strategies implemented and their impacts on the financial performance of private fitness centres.
Willingness to accept compensation for land fallowing: results from a survey of village representatives in Northern China
Authors: Zuo Alec , Wang Jinxia , Huang Qiuqiong 
Published: May 2020

Economic instruments have been increasingly adopted by governments around the world to address water scarcity problems because of their potential to achieve environmental outcomes in more cost‐effective ways. This is the first study to estimate the willingness to accept compensation for land fallowing in rural China. Using survey data collected from village representatives in Northern China (mainly village leaders, party secretaries and village accountants), our results suggest that in groundwater irrigated sample villages, at least 28 per cent of respondents have a compensation expectation lower than the standard level of 500 yuan/mu/year for one season of fallowing set by the Government. Water scarcity measures such as irrigation supply reliability and depth‐to‐groundwater within a village are found to have statistically significant effects on the likelihood of fallowing land in groundwater irrigated villages.
Biodegradation of textile waste by marine bacterial communities enhanced by light
Authors: Girard Elsa B. , Kaliwoda Melanie , Schmahl Wolfgang W. , Wörheide Gert , Orsi William D. 
Published: May 2020

SummaryKnowledge of biofilm formation on pollutants in the marine realm is expanding, but how communities respond to substrates during colonization remains poorly understood. Here, we assess community assembly and respiration in response to two different micropollutants, virgin high‐density polyethylene (HDPE) microbeads and textile fibres under different light settings. Raman characterization, high‐throughput DNA sequencing data, quantitative PCR, and respiration measurements reveal how a stimulation of aerobic respiration by micropollutants is translated into selection for significantly different communities colonizing the substrates. Despite the lack of evidence for biodegradation of HDPE, an increased abundance and respiration of bacterial taxa closely related to hydrocarbonoclastic Kordiimonas spp. and Alteromonas spp. in the presence of textile waste highlights their biodegradation potential. Incubations with textile fibres exhibited significantly higher respiration rates in the presence of light, which could be partially explained by photochemical dissolution of the textile waste into smaller bioavailable compounds. Our results suggest that the development and increased respiration of these unique microbial communities may potentially play a role in the bioremediation of the relatively long‐lived textile pollutants in marine habitats, and that the respiration of heterotrophic hydrocarbon‐degrading bacteria colonizing marine pollutants can be stimulated by light.
Inscribed landscapes in the Black Desert: Petroglyphs and kites at Wisad Pools, Jordan
Authors: Hill Austin Chad , Rowan Yorke M. , Wasse Alexander , Rollefson Gary O. 
Published: May 2020

AbstractPetroglyphs are well known in the Negev, eastern and southern Jordan, and the Arabian Peninsula. Intensive documentation of hundreds of petroglyphs at the site of Wisad Pools in the Black Desert of eastern Jordan records animals, humans, hunting traps and geometric designs, connecting people and places to the larger landscape. These were recorded at the landscape scale with drones and photogrammetry, and the local scale through the construction of a database combined with GPS recording and terrestrial photogrammetry. Petroglyphs of animals and hunting traps are significant because the site is located within a landscape that includes enormous and enigmatic hunting traps (desert kites). Mapping these depictions highlights typological distribution, association of types, and relation to landscape features as well as the topography of the basalt boulders on which they were pecked. The depictions of animals and hunting traps provide clues about the use of desert kites, the social role of hunting, communal gatherings, and feasting in the region.

Published: May 2020

AbstractBackgroundThere is limited research on loop drainage (LD) compared to incision and drainage (I&D) for treatment of cutaneous abscesses. We investigated whether LD was noninferior to I&D for abscess resolution and whether there was any difference in repeat ED visits or complication rates between these techniques.MethodsWe performed a prospective randomized controlled trial, using a convenience sample at an urban academic emergency department (ED). Subjects over 18 years who presented for first‐time management of an abscess were eligible. Patients requiring specialist drainage or hospital admission or had previous treatment for the abscess were excluded. Enrolled subjects were seen 2 weeks after treatment for blinded reevaluation of abscess resolution, and the electronic medical record was reviewed for return ED visits/abscess complications.ResultsOf 2,889 patients screened, 238 subjects consented and were randomized to LD or I&D. Abscess resolution was achieved in 53/65 (81.5%) of patients in the I&D arm, compared to 66/75 (88%) in the LD arm. Fewer patients in the LD group compared to the I&D group returned to the ED for abscess‐related management during the following 14 days (37.3% vs 67.1%, p = 0.002). Among returning subjects, there was a significant difference in mean visits per subject between LD and I&D groups (0.5 vs. 1.2, p = 0.001). There were fewer complications among LD than I&D subjects (9.3% vs. 24.6%, p = 0.01).ConclusionOur study provides evidence that LD is noninferior to I&D in achieving complete abscess resolution at 14 days and is associated with fewer return ED visits and fewer complications. This makes it an attractive alternative treatment option for abscesses.
