Ride-hailing apps' continuance intention among different consumer groups in Indonesia: the role of personal innovativeness and perceived utilitarian and hedonic value
Authors: Fauzi Abu Amar , Sheng Margaret L. 
Published: October 2020

PurposeThis research aims to examine the relationship of personal innovativeness, perceived value (consisting of perceived utilitarian and hedonic value) and continuance intention in the context of ride-hailing apps and to investigate consumer behaviour differences between metro and non-metro consumers.Design/methodology/approachThe survey sample included 402 consumers of popular ride-hailing apps in Indonesia to test the research framework. Then, PLS-SEM-based software was utilised to examine the hypothesised relationship.FindingsThe findings indicate that the effect of personal innovativeness on continuance intention in using ride-hailing apps will operate through the full mediation role of perceived hedonic and utilitarian value, respectively. The findings also show that there are consumer behaviour differences between metro and non-metro consumers, in which the cognitive belief of consumers in the metro areas regarding the usage of ride-hailing apps is more related to hedonic value.Research limitations/implicationsThe variety of respondent demographic profiles in this research is limited in that most of the research respondents are students. In such a case, the study may face the issue of generalisation.Originality/valueThis research generates an extended idea of the information technology continuance model by validating the important role of perceived hedonic and utilitarian value as an integral part of the model and strengthens the insights that Indonesia has consumer behaviour differences regarding technology-based services, particularly ride-hailing apps, between metro and non-metro consumers.

Published: October 2020

PurposeThis paper aimed to introduce a systematic body of knowledge via a scientometric review, guiding the sustainable transition from conventional construction to prefabricated construction. The construction industry currently faces a challenge to balance sustainable development and the construction of new buildings. In this context, one of the most recent debates is prefabricated construction. As an emerging construction approach, although existing knowledge makes contributions to the implementation of prefabricated construction, there is a lack of a comprehensive and in-depth overview of the critical knowledge themes and gaps.Design/methodology/approachThis study uses the scientometric analysis to review the state-of-the-art knowledge of prefabricated construction. It retrieved data from the Web of Science core collection database. CiteSpace software was used to conduct the analysis and visualization; three analysis methods identify the knowledge hotspots, knowledge domains and knowledge topics. Finally, according to integrating the hidden connections among results, a body of knowledge for prefabricated construction application can be inferred.FindingsThe results show that 120 knowledge hotspots, five critical knowledge domains and five prominent knowledge topics are vital for promoting implementation of prefabricated construction. Based on the afore analysis, a body of knowledge for prefabricated construction that can systematically cover a broad knowledge of prefabricated construction-related research and activities are integrated and proposed in this paper.Originality/valueBody of knowledge systematically covers a broad knowledge of prefabricated construction applications and is vital to guide researchers and practitioners to conduct related research and activities, thereby promoting the sustainable transition to prefabricated construction implementation.

Authors: Herold David M. , Dietrich Timo , Breitbarth Tim 
Published: October 2020

PurposeThis study aims to identify and deconstruct bullshit in banks' corporate social responsibility (CSR) communication to advance the management rhetoric research space, which has been characterised by an indifference to truth and meaning.Design/methodology/approachWe provide a typology of bullshit phenomena overview in the banking sector and follow the McCarthyet al.'s (2020) C.R.A.P. framework from to showcase how bullshit can be comprehended, recognised, acted against and prevented.FindingsThis paper puts a spotlight on written and spoken language to detect bullshit in banks' CSR statements. It provides actionable insights into how stakeholders can act against and prevent bullshit statements from occurring in the future.Research limitations/implicationsFuture research is warranted to assess the use of still imagery, events and video materials in corporate communications and non-financial reporting. Further rigorous assessment of actual CSR initiatives must be undertaken to assess claimed contributions.Practical implicationsMonitoring mechanisms and independent assurance statements prepared by authorised third parties may strengthen the motivation and ethicality of CSR activities.Originality/valueThis viewpoint is the first to follow the C.R.A.P framework and critically assess indifferences towards truth in banks' CSR communications.
Price premium of private placement: evidence from India
Authors: Katti Supriya , Verma Naval , Phani B.V. , Ghosh Chinmoy 
Published: October 2020

PurposeThis study identifies the factors responsible for obtaining price premium on privately placed equity in a developing market.Design/methodology/approachWe examine a unique data set of a special case of private placement of equity, Qualified Institutional Placement (QIP) in India purchased at a premium. The study analyzed 188 equity issues offered between September 2006 and December 2014. On average, we find that QIP issues received a price premium of 4.38%. The study employed binary probit and ordinary least square regression models to analyze the probability and magnitude of the premium.FindingsThe study attributes the price premium of QIP to certification effect through group affiliation, signaling through promoters' ownership and monitoring effect through existing institutional investors. These factors influence the probability of premium for QIP issues. However, group affiliation and institutional ownership do not significantly influence the magnitude of the premium.Originality/valueThe private placement of equity is usually offered at a discount. Our findings contribute to the existing literature by evaluating the premium obtained on private placement as a unique scenario in emerging market supported through certification hypothesis, monitoring hypothesis and signaling.

Published: October 2020

PurposeThis study aims to investigate whether human capital readiness affects business performance, and if so, whether the effect is mediated by global market orientation.Design/methodology/approachThis is a quantitative study employing partial least square structural equation modeling (PLS-SEM) to test the hypotheses. Using a survey method, the data were collected using both online and offline questionnaires. As many as 433 owners/managers of micro-, small- and-medium-sized enterprises (MSMEs) in the East Java Province of Indonesia participated in this study. A mediating research framework was developed to investigate the mediating role of global marketing orientation on the human capital readiness–business performance relationship.FindingsThe results show that human capital readiness has a direct and positive effect on business performance. Further analysis reveals that global market orientation partially mediates the effect of human capital readiness on business performance.Research limitations/implicationsFirst, this study focuses on the MSMEs in the East Java Province of Indonesia. Caution needs to be taken if the results are generalized to other regions. Second, it employed a survey method that is commonly criticized as having the potential to be biased.Practical implicationsThe findings provide a more comprehensive understanding of owners/managers of human capital readiness and how it should be improved to better execute global market orientation strategies to achieve the desired business performance.Social implicationsBecause MSMEs play a crucial role in society, this study provides a general model to improve the welfare of society by enhancing the MSMEs' business performance. By understanding its antecedents, namely, human capital readiness and the global market orientation, improvements can be made.Originality/valueHuman capital readiness has been rarely examined in previous studies. This is the only study applying the constructs of human capital readiness, global market orientation and business performance to the Indonesian MSME research setting.

Evaluate efficiency of TPM implementation is considered as a key element in order to motivate staff and to give decision-makers more confidence.Design/methodology/approachThis study consists in developing a new method of evaluating TPM implementation, relying on analytical models and considering two preventive maintenance strategies: periodic and age-dependent.FindingsThe preventive maintenance period and TPM period defined as decision variables are obtained simultaneously by maximizing the expected profit under TPM implementation. A numerical example is presented and a sensitivity study is developed to validate the proposed models.Originality/valueThe aim of this research is to quantify, through analytic development, the impact of TPM implementation in a company by calculating and comparing the profit made with and without TPM.
Effect of temperature on wear and friction behavior of as-cast and heat-treated LM25/SiC aluminum matrix composites
Authors: Mehta Vishal R. , Sutaria Mayur P. 
Published: November 2020

Purpose
The purpose of this paper is to evaluate the influence of temperature, load and sliding speed on wear and friction behavior of LM25/SiC composites in as-cast and heat-treated conditions.

Design/methodology/approach
The LM25/SiC aluminum matrix composites (AMCs) were prepared using the stir casting process. The wear tests were carried out using a pin-on-disc setup in dry condition. The three levels of each parameter, i.e. 100, 150 and 200°C operating temperature; 15, 25 and 35 N load; 0.8, 1.6 and 2.4 m/sec sliding speed, were considered for the investigation. ANOVA has been carried out to evaluate the percentage contribution of parameters. Scanning electron microscope analysis of worn surfaces has been carried out to understand the wear mechanism.

Findings
The wear and coefficient of friction (COF) increase with the increase in the temperature, load and sliding speed within a selected range for as-cast as well as heat-treated LM25/SiC AMCs. The mean values of wear and COF in heat-treated samples were found to be lower than as-cast samples for all cases. It was observed that the percentage wear increases significantly as temperature increases in as-cast AMCS. Mild to severe wear transition was observed at 150°C. In heat-treated AMCs, mild wear was observed irrespective of temperature. It was also observed that as the temperature increases, transition of wear mechanism from abrasive to adhesive (including delamination) occurs earlier in as-cast samples as compared to heat-treated samples.

Originality/value
There is a lack of data on combined effect of temperature, load and sliding speed on tribological aspects of as-cast and heat-treated LM25/SiC AMCs, limiting its applications. The present research work has addressed this gap.
Flower biology of the cactus Coryphantha elephantidens in the tropical dry forest of Central Mexico
Authors: Martínez‐Peralta Concepción , Martínez‐Zavala Angélica 
Published: November 2020

AbstractFloral traits and sexual systems in angiosperms are strategies that enhance outcrossing within hermaphrodite flowers and among individuals in a population. Sexual systems with unisexual flowers have also evolved among angiosperms, resulting in sex specialization. Furthermore, the interaction of floral traits and floral visitors determines successful plant reproduction. Globose cacti are bee pollinated, and variation in the diversity of their pollinator assemblages is strongly associated with floral phenotype. Our objective was to describe the floral biology of the cactus Coryphantha elephantidens and to determine its relationship with pollinators. Floral traits were studied by direct observations in live and fixed flowers. The breeding system was determined using two estimators based on floral morphology: pollen grains to ovules per flower (P/O) ratio and outcrossing index. Pollination treatments were conducted to determine the mating system. Floral visitors were recorded using direct observation. Flowers of C. elephantidens are variable in color, protandric, herkogamous and nectarless. Estimators of the breeding system indicated xenogamy, which is consistent with the obligate outcrossing revealed by the pollination experiment. Thirty‐seven percent of the plants have female flowers that do not produce pollen, making this population functionally gynodioecious. Both fruit and seed set were high compared to other globose cacti. Pollinators included eight species of native bees, a more diverse pollinator assemblage than other globose cacti. Given the high pressure on pollen due to functional gynodioecy, nectarless flowers, an outcrossing mating system, and the necessity of pollinators to set seeds, we concluded that native bees are highly efficient pollinators that play a crucial role in the sexual reproduction of C. elephantidens.
Do Consumers Really Care? An Economic Analysis of Consumer Attitudes Towards Food Produced Using Prohibited Production Methods
Authors: Balcombe Kelvin , Bradley Dylan , Fraser Iain 
Published: October 2020

AbstractConsumer preferences for food produced using currently prohibited production methods matter, especially in relation to potential trade deals. We conduct four discrete choice experiments examining UK consumer attitudes for food produced using several agricultural production methods currently prohibited in the UK, including chlorine washed chicken. Our results reveal negative preferences for these forms of agricultural production methods whereas EU food safety standards are highly valued. Willingness‐to‐pay estimates indicate that the positive values for food safety are frequently greater than the negative values placed on prohibited food production methods. Similarly, UK country of origin was highly valued but organic production was less valued. We discuss the implications of these results and, more generally, the use of stated preference estimates in economic modelling underpinning trade negotiations.
Hydroxycinnamic acids on gut microbiota and health
Authors: Leonard William , Zhang Pangzhen , Ying Danyang , Fang Zhongxiang 
Published: October 2020

AbstractHydroxycinnamic acids (HCAs) are a major class of phenolic acids with the characteristic phenylpropanoid C6‐C3 backbone. Its typically conjugated status with plant cell wall components and liberation by limited enzymes might be the reason for its neglect by researchers compared to flavonoid‐type polyphenols. The polyphenol–gut microbiota interactions and their impact on human health have captured the interest of researchers recently. In addition, there has been a significant progress over the past few years in understanding the gut microbiota‐modulating effect of HCA using animal model studies. This review discusses the metabolism of HCA in the digestive tract, HCA–gut microbiota interactions, and its link to colorectal cancer, inflammatory bowel diseases, mental‐cognitive impairments, nonalcoholic liver disease, and obesity. The effects of food matrix and processing technologies on HCA bioavailability and HCA–gut microbiota interactions, and HCA safety concerns are also featured in this review. This paper has provided an in‐depth insight on HCA–gut microbiota relationship and identified the current literature gaps for future research.
Olfaction alters spatial memory strategy of scatter‐hoarding animals
Authors: YI Sijie , WANG Minghui , JU Mengyao , YI Xianfeng 
Published: November 2020

AbstractAlthough it has been suggested that olfaction is closely interconnected with hippocampal systems, whether olfaction regulates spatial memory strategy remains never known. Furthermore, no study has examined how olfaction mediates spatial memory established on the external objects, for example, caches made by scatter‐hoarding animals. Here, we experimentally induced nondestructive and reversible olfaction loss of a scatter‐hoarding animal Leopoldamys edwardsi, to test whether and how olfaction regulates spatial memory to mediate cache recovery and pilferage. Our results showed that the normal L. edwardsi preferred to pilfer caches of others rather than to recover their own using accurate spatial memory (35.7% vs. 18.6%). Anosmic L. edwardsi preferred to recover the caches they made prior to olfaction loss rather than to pilfer from others relied on spatial memory (54.2% vs. 36.0%). However, L. edwardsi with anosmia showed no preference either to the caches they established after olfaction loss or caches made by others (25.8% vs. 29.1%). These collectively indicate that olfaction loss has a potential to affect new memory formation but not previously established spatial memory on caches. Our study first showed that olfaction modified spatial memory strategy in cache recovery and pilferage behaviors of scatter‐hoarding animals. We suggest that future studies pay more attention to the evolution of olfaction and its relationship with spatial memory strategy.

SummaryButenyl‐spinosyn, a promising biopesticide produced by Saccharopolyspora pogona, exhibits stronger insecticidal activity and a broader pesticidal spectrum. However, its titre in the wild‐type S. pogona strain is too low to meet the industrial production requirements. Deletion of non‐target natural product biosynthetic gene clusters resident in the genome of S. pogona could reduce the consumption of synthetic precursors, thereby promoting the biosynthesis of butenyl‐spinosyn. However, it has always been a challenge for scientists to genetically engineer S. pogona. In this study, the Latour gene knockout system (linear DNA fragment recombineering system) was established in S. pogona. Using the Latour system, a hybrid NRPS‐T1PKS cluster (˜20 kb) which was responsible for phthoxazolin biosynthesis was efficiently deleted in S. pogona. The resultant mutant S. pogona‐Δura4‐Δc14 exhibited an extended logarithmic phase, increased biomass and a lower glucose consumption rate. Importantly, the production of butenyl‐spinosyn in S. pogona‐Δura4‐Δc14 was increased by 4.72‐fold compared with that in the wild‐type strain. qRT‐PCR analysis revealed that phthoxazolin biosynthetic gene cluster deletion could promote the expression of the butenyl‐spinosyn biosynthetic gene cluster. Furthermore, a TetR family transcriptional regulatory gene that could regulate the butenyl‐spinosyn biosynthesis has been identified from the phthoxazolin biosynthetic gene cluster. Because dozens of natural product biosynthetic gene clusters exist in the genome of S. pogona, the strategy reported here will be used to further promote the production of butenyl‐spinosyn by deleting other secondary metabolite synthetic gene clusters.
Mastering organismal aging through the endoplasmic reticulum proteostasis network
Authors: Taylor Rebecca C. , Hetz Claudio 
Published: October 2020

AbstractThe aging process is characterized by a progressive decline in the function of most tissues, representing the main risk factor in the development of a variety of human diseases. Studies in multiple animal models have demonstrated that interventions that improve the capacity to maintain endoplasmic reticulum (ER) proteostasis prolong life and healthspan. ER stress is monitored by the unfolded protein response (UPR), a signaling pathway that mediates adaptive processes to restore proteostasis or the elimination of damaged cells by apoptosis. Here, we discuss recent advances in understanding the significance of the UPR to aging and its implications for the maintenance of cell physiology of various cell types and organs. The possible benefits of targeting the UPR to extend healthspan and reduce the risk of developing age‐related diseases are also discussed.

Published: October 2020

AbstractTetropium gabrieliis native to the European Alps where it breeds in European larch and may be an important pest during drought periods by killing trees. It has spread to larch plantations in several European countries including Sweden.In trapping studies conducted in Sweden, we tested whetherT. gabrieliwas attracted toE‐fuscumol,E,Z‐fuscumol,E,Z‐fuscumol acetate and the host volatile combination of α‐pinene plus ethanol. We also compared its response with those of the native congeners,T. fuscumandT. castaneum.All threeTetropiumspecies were caught in significantly higher numbers in traps baited withE‐fuscumol plus host volatiles than in traps baited with host volatiles alone or in unbaited traps.There was no difference in catch of anyTetropiumspecies between traps baited withE‐fuscumol plus host volatiles versus traps baited withE,Z‐fuscumol plus host volatiles, but the latter treatment caught moreT. fuscumandT. castaneumthan didE,Z‐fuscumol acetate plus host volatiles.The addition ofE‐fuscumol to host volatile‐baited traps significantly reduced mean catch ofT. gabrieli,significantly increased mean catch ofT. castaneum,and had no significant effect on catch ofT. fuscum.Mean catch of all three species was significantly greater in traps baited withE‐fuscumol alone than in traps baited with host volatiles alone.All three species were caught from May to August. The median date of captures was about 2 weeks earlier forT. fuscumcompared with the other two species.
