Buy Muslim-made first – does halal consciousness affect Muslims’ intention to purchase?
Authors: Hassan Siti Hasnah , Mat Saad Norizan , Masron Tajul Ariffin , Ali Siti Insyirah 
Published: October 2020

PurposeBuy Muslim’s First campaign started with the primary aim of urging the Muslim community to be more vigilant about halal or Shariah-compliant products, leading to a number of halal-related issues, triggered by the exploitation or misuse of the halal logo in Malaysia. The purpose of this study is to gain an understanding of the purchase intention for Muslim-made products by applying the theory of planned behaviour (TPB). Halal consciousness was integrated as a moderating influence on the purchase intention of Muslim-made products.Design/methodology/approachData collection was performed through a self-administered questionnaire which was distributed through convenience sampling method. Therefore, a useful sample comprising 152 Malay Muslim participants aged over 18 was collected. For hypothesis testing, hierarchical multiple regression analysis was implemented.FindingsIt was found that the participants’ attitudes towards the purchase of Muslim-made products and their perceived behavioural control significantly influenced their purchase intention, but the subjective norm did not impact this intention. Furthermore, halal consciousness moderated the relationships among all the independent and dependent variables. Halal consciousness moderated the relationship between participants’ attitudes towards Muslim-made products and their perceived behavioural control towards the purchase intention; however, this moderation did not occur through the subjective norm and the purchase intention.Research limitations/implicationsAs the findings of this study were limited to the Muslim population in Malaysia, it might be difficult to generalize for other nations that have no similarities with the Malaysian Muslim culture.Practical implicationsThe findings of this study may support Muslims to implement more effective marketing strategies that attract the target customers to purchase Muslim-made products. Effective promotion may attract potential customers as well.Originality/valueThe halal consciousness among Muslim consumers is important for the moderation and prediction of consumers’ intention to purchase Muslim-made products.
Surprisingly stable: an experiment on willingness to bear uncertainty in individuals with and without entrepreneurial intentions
Authors: Zichella Giulio 
Published: October 2020

PurposeEntrepreneurs are often considered to be more willing to bear and manage uncertainty than non-entrepreneurs. However, the available empirical evidence regarding this topic is limited and mixed. By adopting an experimental design, the paper’s purpose is to shed light on a causal mechanism behind decision making under uncertainty.Design/methodology/approachThis paper outlines the performance of a quasi-laboratory experiment that investigates whether a lack of predictive information affects individuals with entrepreneurial intentions in their likelihood to choose uncertainty vis-à-vis certainty. Drawing on prospect theory, it is argued that individuals with entrepreneurial intentions are less sensitive than individuals without entrepreneurial intentions due to a framing effect that occurs when information about probabilities is manipulated. In particular, it is argued that individuals with entrepreneurial intentions are more likely than their comparable counterparts to choose consistently among monetary opportunities that share everything in common but information about probabilities of success.FindingsThis study finds support for the argument, as individuals with entrepreneurial intentions have preferences pertaining to uncertainty that are more stable compared to those of individuals without such intentions. The results hold after controlling for a number of alternative explanations, including status quo bias, prior gain effect and degree of risk effect.Originality/valueThe paper tackles a fundamental issue in entrepreneurship—namely behavior under uncertainty—by adopting a novel approach. In particular, an experimental design is used to test for causality between availability of information and choices involving monetary rewards. Results have implications for the understanding of factors that guide entrepreneurial choices under uncertainty and, ultimately, entrepreneurial action.
“Are you crewed up with that bird from the uni?” the complexities of conducting ethnographic research in policing
Authors: Cox Claudia Emeline 
Published: October 2020

PurposeThe purpose of this paper is to provide some initial reflections on the complexities and challenges faced when conducting observations with police officers working in response and neighbourhood policing roles from the perspective of a young, female, researcher.Design/methodology/approachThe research consisted of 200 hours spent with operational police officers in a medium sized UK police force, predominantly in 3 cities, to explore the realities of frontline policing and policy implementation. This paper offers a reflexive account of conducting the research, as opposed to a discussion of the findings which align to the original research aim.FindingsConducting this fieldwork highlighted a number of complexities arising as a result of conducting ethnographic research in policing. This paper is concerned with the constructing of a researcher identity and navigating moral dilemmas based on the culture and use of language observed.Originality/valueWhilst this will be of interest to those engaged with similar policing research, such findings are also likely to apply to those conducting ethnography where there is conflict between their insider/outsider status, the potential for internalised moral debates and women conducting research in male-dominated settings.
Drivers and consequences of customer participation into value co-creation: a field experiment
Authors: Guzel Mevludiye , Sezen Bülent , Alniacik Umit 
Published: October 2020

Purpose
This paper aims to analyze value co-creation (VCC) in new product development from consumer’s perspective. It offers a holistic approach to consumers’ VCC behavior with its before (drivers) and after (consequences) stages.

Design/methodology/approach
Three consecutive studies are carried out to test the hypotheses examining the antecedents and results of co-creation behavior, as well as the behavior itself in a new headphones design context. The experimental data have been collected from 934 university students within a period of six months.

Findings
Findings suggest that extraversion and openness to experience increase consumers’ willingness to participate in VCC. Celebrity endorsers and product category involvement also affect this tendency. When consumers display co-creation behavior, they intend to purchase the product to be co-created. However, they are especially keen to buy this co-created product when their contributions are embodied in it.

Originality/value
Previous studies focus on intentions, lacking a detailed analysis of actual VCC behavior. By shedding light on co-creation behavior with its before and after stages, this paper contributes to co-creation literature with a field experiment. Consumers’ co-creation behavior has been observed in the context of new product development, which is mostly occupied by business to business research. Therefore, the results also add to research on new product development in business to consumer contexts.

Published: October 2020

PurposeThis study provides a unique integrated diagnosis system to investigate the causes of low productivity, profitability, machinery health conditions and wear severity of medium-size biscuit industry assets in Taiz, Yemen.Design/methodology/approachThe evaluation is based on an integrating of the overall equipment effectiveness (OEE) and oil-based maintenance (OBM) approaches. The data are collected using the company's operational records, interviews and observations, while the used lubricating oil samples are also collected from production lines' machineries. Scanning electron microscope (SEM) is used to study the wear debris particle features and wear mechanism. Different other analysis tools such as fishbone, 5 whys and Pareto charts are also used to investigate the root causes and plausible recovery solutions of machinery failures.FindingsThis study demonstrated that a large proportion of machinery failures and production loss are of management concerns. Also, this study inferred that the analysis of wear debris is unique and informative for determining machinery wear severity and useful life. Finally, the current conditions of production lines are clarified and suggestions to use a mixed preventive/predictive maintenance management approach are also elucidated.Originality/valueThis work implemented an integrated OEE/OBM diagnostic maintenance system to investigate the root causes of low productivity and machine failures in real production lines and suggested robust decisions on the maintenance duties.
When does Main Street prefer Wall Street? Legitimacy, status, and decision-making
Authors: Altura Thomas G. 
Published: October 2020

PurposeWhen and why do organizations prefer high-status exchange partners? While past work has focused on status as a signal to the marketplace, this study shows that actors use the selected organization's status as a signal to legitimate their own selection decision.Design/methodology/approachThe context of the study is the selection of investment banks by local governments in the United States for the purpose of selling municipal bonds to investors. Hypotheses were developed through interviews with participants in the public and private sectors and were then tested using generalized estimating equations (GEEs). The models include 6,720 selection decisions nested within 1,032 local governments.FindingsInterview data reveal that governmental decision-makers struggle with interdepartmental conflict and are concerned about the perceived legitimacy of decisions in the “political arena”. The quantitative results confirm that with respect to selection decisions, the social context of the local government matters. Specifically, racial/ethnic heterogeneity, political competition and functional complexity—contexts where actors must signal independence and objectivity in decision-making—are each associated with an increased likelihood of retaining a high-status investment bank.Originality/valueThe study shows that a preference for a high-status partner is not just market driven. Rather, it emerges also from the legitimacy demands of the organization's own participants. More broadly, the study reveals how organizational decision-making—even that pertaining to the external market environment—is embedded in an organization-specific social reality.
Independent publishers and social networks in the 21st century: the balance of power in the transatlantic Spanish-language book market
Authors: Gallego-Cuiñas Ana , Romero-Frías Esteban , Arroyo-Machado Wenceslao 
Published: October 2020

PurposeThe present paper uses Twitter to analyze the current state of the worldwide, Spanish-language, independent publishing market. The main purposes are to determine whether certain Latin American Spanish-language independent publishers function as gatekeepers of world literature and to analyze the geopolitical structure of this global market, addressing both the Europe-America dialectic and neocolonial practices.Design/methodology/approachAfter selecting the sample of publishers, the authors conducted a search for their Twitter profiles and located 131; they then downloaded data from the corresponding Twitter APIs. Finally, they applied social network analysis to study the presence of and interaction between the sample of independent publishers on this social media.FindingsThe results provide data-based evidence supporting the hypothesis of some literary critics who suggest that in Latin America, certain publishers act as gatekeepers to the mainstream book market. Therefore, Twitter could be considered a valid source of information to address the independent book market in Spanish. By extension, this approach could be applied to other cultural industries in which small and medium-sized agents develop a digital presence in social media.Originality/valueThis paper combines social network analysis and literary criticism to provide new evidence about the Spanish-language book market. It helps validate the aforementioned hypothesis proposed by literary critics and opens up new paths along which to pursue an interpretative, comparative analysis.
The Price for Market Embeddedness is Declining Adaptive Capabilities: Model, Measurement and Illustration
Authors: Liu Min , Pólos László , Hannan Michael T. 
Published: October 2020

AbstractThis paper deals with a central challenge in organization and management research: to predict the evolution of an organization's adaptive capability. We address both theoretical and methodological gaps in existing research. First, focusing on the largely overlooked external constraints on adaptive capability, we model how ties between an organization and its market audiences curtail adaptive capability as market tenure increases. Second, we address the methodological weakness of conceptualizing the content of organizational change in prior research with a novel approach. Our distance‐based approach sees adaptation as change in an organization's position in a cognitive market space. With position defined, one can measure the speed of movement in that space. An analysis of the UK motorcycle market serves as an empirical illustration for our theoretical prediction and proposed measure.

Authors: Kaur Anudeep , Singh Nirmal , Bhatti Manpreet Singh , Bhatti Rajbir 
Published: October 2020

AbstractThe plant Angelica archangelica, owing to its magnificent therapeutic effectiveness in folklore medicine system, has been regarded as an “angel plant.” The current investigation was aimed to optimize extraction conditions of A. archangelica roots and to investigate in vivo role of optimized extract in fibromyalgia. Plant material (dried roots) was subjected to methanol extraction at variable temperature (40 to 60 °C) and time (12 to 36 hr) conditions as per two‐factorial design strategy, and responses in terms of antioxidant activity were determined. The optimized extraction conditions were found to be temperature of 60 °C and time of 36 hr. HPLC fingerprinting indicated the presence of coumarins in extract. To induce fibromyalgia, the mice were administered reserpine at a dose of 0.5 mg/kg. Mice were orally treated with 100, 200, and 400 mg/kg extract, and magnitude of fibromyalgia was quantified. In comparison to reserpine group, the extract treatment attenuated pain as shown by significant increase in paw withdrawal threshold against mechanical stimuli (P < 0.05), improved motor ability indicated by increase in fall‐off time in inclined plane test (P < 0.05), improved locomotion indicated by increased square crossings in open field test (P < 0.05), and improved cognition as shown by significant reduction in time to reach platform in Morris water maze test and passive avoidance task test (P < 0.05). Extract treatment significantly halted reserpine‐induced rise in serum cytokine level (P < 0.05) and brain oxidative stress (P < 0.05). Angelica archangelica extract exerted its beneficial effects in fibromyalgia possibly through the attenuation of oxidative stress‐mediated inflammatory cascade.Practical ApplicationLeads from natural products have become an integral part of drug designing processes and have high acceptability due to their better tolerance. The optimization of extraction conditions of plant yields better results and could reduce the processing time, thus increasing its industrial value.
An automated DIY framework for experimental evolution of Pseudomonas putida
Authors: Espeso David R. , Dvořák Pavel , Aparicio Tomás , de Lorenzo Víctor 
Published: October 2020

SummaryAdaptive laboratory evolution (ALE) is a general and effective strategy for optimizing the design of engineered genetic circuits and upgrading metabolic phenotypes. However, the specific characteristics of each microorganism typically ask for exclusive conditions that need to be adjusted to the biological chassis at stake. In this work, we have adopted a do‐it‐yourself (DIY) approach to implement a flexible and automated framework for performing ALE experiments with the environmental bacterium and metabolic engineering platform Pseudomonas putida. The setup includes a dual‐chamber semi‐continuous log‐phase bioreactor design combined with an anti‐biofilm layout to manage specific traits of this bacterium in long‐term cultivation experiments. As a way of validation, the prototype was instrumental for selecting fast‐growing variants of a P. putida strain engineered to metabolize D‐xylose as sole carbon and energy source after running an automated 42 days protocol of iterative regrowth. Several genomic changes were identified in the evolved population that pinpointed the role of RNA polymerase in controlling overall physiological conditions during metabolism of the new carbon source.
Wing: A suitable nonlethal tissue type for repeatable and rapid telomere length estimates in bats

Published: October 2020

AbstractTelomeres are used increasingly in ecology and evolution as biomarkers for ageing and environmental stress, and are typically measured from DNA extracted from nonlethally sampled blood. However, obtaining blood is not always possible in field conditions and only limited amounts can be taken from small mammals, such as bats, which moreover lack nucleated red blood cells and hence yield relatively low amounts of DNA. As telomere length can vary within species according to age and tissue, it is important to determine which tissues serve best as a representation of the organism as a whole. Here, we investigated whether wing tissue biopsies, a rapid and relatively noninvasive tissue collection method, could serve as a proxy for other tissues when measuring relative telomere length (rTL) in the Egyptian fruit bat (Rousettus aegyptiacus). Telomeres were measured from blood, brain, heart, kidney, liver lung, muscle and wing, and multiple wing biopsies were taken from the same individuals to determine intra‐individual repeatability of rTL measured by using qPCR. Wing rTL correlated with rTL estimates from most tissues apart from blood. Blood rTL was not significantly correlated with rTL from any other tissue. Blood and muscle rTLs were significantly longer compared with other tissues, while lung displayed the shortest rTLs. Individual repeatability of rTL measures from wing tissue was high (>70%). Here we show the relationships between tissue telomere dynamics for the first time in a bat, and our results provide support for the use of wing tissue for rTL measurements.

Published: October 2020

AbstractMarrow adipocytes and osteoblasts differentiate from common mesenchymal progenitors in a mutually exclusive manner, and diversion of these progenitors toward adipocytes in old age has been proposed to account for the decline in osteoblasts and the development of involutional osteoporosis. This idea has been supported by evidence that thiazolidinedione (TZD)‐induced activation of PPARγ, the transcription factor required for adipocyte differentiation, increases marrow fat and causes bone loss. We functionally tested this hypothesis using C57BL/6J mice with conditional deletion of PPARγ from early mesenchymal progenitors targeted by the Prx1‐Cre transgene. Using a longitudinal littermate‐controlled study design, we observed that PPARγ is indispensable for TZD‐induced increase in marrow adipocytes in 6‐month‐old male mice, and age‐associated increase in marrow adipocytes in 22‐month‐old female mice. In contrast, PPARγ is dispensable for the loss of cortical and trabecular bone caused by TZD or old age. Instead, PPARγ restrains age‐dependent development of cortical porosity. These findings do not support the long‐standing hypothesis that increased marrow adipocyte differentiation contributes to bone loss in old age but reveal a novel role of mesenchymal cell PPARγ in the maintenance of cortical integrity.

Published: October 2020

AbstractBackgroundThe appendix has a unique place in surgical history. Although the first ever appendicectomy involved a fistula to the skin, fistulae involving the appendix remain uncommon and can lead to unique surgical considerations.MethodsA systematic review of the literature was performed for case reports of appendiceal fistulae. We excluded cases in which the patient had a history of appendicectomy. Cases were categorized by site and aetiology, with information regarding relative frequency and demographics obtained.ResultsA total of 301 case reports of fistula involving the appendix were found. The most common sites of these fistulae were to the bladder (148 cases), skin (40 cases), vasculature (19 cases), umbilicus (16 cases) and to the gastrointestinal tract. The most common aetiology in sub‐analysis was appendicitis alone (150 cases), with less common causes including appendiceal adenocarcinoma (32 cases) and congenital abnormalities (18 cases). There were significantly more appendiceal fistulae in males than in females, with a ratio of 1.7:1. In patients with appendiceal adenocarcinoma as a cause for fistula, there were significantly more females than males with a ratio of 2.3:1.ConclusionIn conducting a systematic review of case reports of fistulae involving the appendix, we identified 301 unique case reports, with a range of different sites and aetiologies.
