Animating business relationships through community social capital: an insight into conviviality
Authors: Guercini Simone , Ranfagni Silvia 
Published: July 2021

Purpose
As conviviality can nurture community social capital, this paper aims to investigate how such capital can give rise to economic behaviour in terms of developing business relationships.

Design/methodology/approach
The empirical analysis was based on case studies of Italian businesses recognised as active communities that periodically organise convivial activities to fuel reciprocal collaboration. The case studies were constructed by combining a collection of secondary data, in-depth interviews and participant observations.

Findings
This paper shows how: community social capital in convivium emerges from self-narrative stimulated by ritual practices; social trust mobilising a convivial social capital is fuelled by knowledge generated through sharing and empathic relationships; community-based social relations embed business relations and if mediated, community-based business relations can also embed a community business.

Originality/value
The originality of the paper is twofold as it contributes: to understanding how conviviality can be used as a strategic tool for entrepreneurs to develop business relationships from convivial relations; and to finding intersection points between studies on business relationships from social capital and studies on entrepreneurship from community social capital.
When collusion meets the fraud triangle: a case study approach
Authors: Villaescusa Núria , Amat Oriol 
Published: July 2021

Purpose
The purpose of this paper is to explore how the different elements of the fraud triangle are present in a case of convicted accounting fraud in collusion.

Design/methodology/approach
This is a case study research.

Findings
The authors find that when a fraud is carried out in collaboration of several internal and external members of the company, the view of the fraud triangle as an explanation of the fraud from a heuristic point of view is a very limited perspective of the fraud as an opportunity has been designed ad hoc for the fraud commission.

Originality/value
Although there is a vast research on accounting fraud, collusion fraud is still an unexplored area. This study gives light on how a real case of fraud is perpetrated.
Safety culture in healthcare: mixed method study
Authors: Lorenzini Elisiane , Oelke Nelly D. , Marck Patricia B. 
Published: July 2021

PurposeHealthcare providers’ perceptions of management's effectiveness in achieving safety culture improvements are low, and there is little information in the literature on the subject. Objective: The overall aim of this study was to examine the patient safety culture within an interprofessional team – physicians, nurses, nurse technicians, speech therapist, psychologist, social worker, administrative support – practicing in an advanced neurology and neurosurgery center in Southern Brazil.Design/methodology/approachThe authors applied the safety attitudes questionnaire (SAQ) in a mixed methods study, with a quan→QUAL sequential explanatory approach.FindingsIn the quantitative phase, the authors found a negative safety climate through the SAQ. In the qualitative phase, the approach enabled participants to identify specific safety problems. For that, participants proposed improvements that were directly and quickly implemented in the workplace during the study. The joint analysis of the quantitative and qualitative data inferred that the information and reflections of the focus group participants supported and validated the SAQ statistical analysis results. This integrated approach illustrated the importance of various safety culture aspects as a multifaceted phenomenon related to healthcare quality.Originality/valueThis study provides explanations for why management is associated negatively with safety climate in healthcare institutions. In addition, the study provides a novel contribution adding value to mixed methods research methodology.
The influence of attitude functions on Muslim consumer attitude towards social media advertising: a case of bubble tea
Authors: Kamalul Ariffin Shaizatulaqma , Ihsannuddin Nur Qistina , Abdul Mohsin Ainul Mohsein 
Published: July 2021

Purpose
The purpose of this paper is to examine the relationship between attitude functions and attitude towards social media advertising. Additionally, this study also examines the relationship between attitude towards social media advertising and purchase intention.

Design/methodology/approach
The data was collected via an online survey among Malaysian Muslim participants. Quantitative analysis was used to test the hypothesis. A total of 280 respondents participated in the online survey but only 264 responses fit the analysis. The data was analysed via SPSS and partial least squares structural equation modelling.

Findings
The findings of this paper show that attitude functions, namely, utilitarian, value-expressive, ego-defensive and religiosity have a significant positive influence on attitude towards social media advertising, whilst knowledge function was found to be insignificant. Attitude towards social media advertising was also found to have a significant positive influence on purchase intention.

Practical implications
Advertisers should also consider the religious aspects of Muslim consumers and their level of sensitivity as Muslims nowadays are well-informed. This is to avoid controversies and have a better understanding of their consumer needs.

Originality/value
This is one of the few studies examining the influence of religiosity in the social media advertising of controversial products such as bubble tea.
Role of leadership, strategic planning and entrepreneurial organizational culture towards achieving organizational excellence: evidence from public sector using SEM
Authors: Al-Dhaafri Hassan , Alosani Mohammed Saleh 
Published: July 2021

Purpose
The purpose of this study is to study the collective effect of leadership, strategic planning and entrepreneurial organizational culture (EOC) on organizational excellence.

Design/methodology/approach
Using primary data obtained through a survey questionnaire, hypotheses have been developed for testing. Out of a total of 565 questionnaires, only 355 questionnaires were returned where data were collected from the Dubai police organization. The structural equation modelling (SEM) approach was used to analyse the collected data.

Findings
Statistical findings using SEM-partial least square confirmed the full mediating role of strategic planning as a mechanism between leadership and organizational excellence. In addition, the results reported a significant effect of leadership on strategic planning besides its impact on organizational excellence.

Practical implications
Results reported many valuable implications. The outcomes of this study have practical implications that will help managers, decision-makers and practitioners to consider the study’s variables to enhance the overall performance through achieving excellence.

Originality/value
The collective role of leadership, strategic planning, EOC and organizational excellence is studied as one of the most important empirical studies which bring original contribution to the existing body of knowledge.
Heads-up! An alert and warning system for phishing emails
Authors: Cooper Molly , Levy Yair , Wang Ling , Dringus Laurie 
Published: July 2021

PurposeThis study introduces the concept of audiovisual alerts and warnings as a way to reduce phishing susceptibility on mobile devices.Design/methodology/approachThis study has three phases. The first phase included 32 subject matter experts that provided feedback toward a phishing alert and warning system. The second phase included development and a pilot study to validate a phishing alert and warning system prototype. The third phase included delivery of the Phishing Alert and Warning System (PAWSTM mobile app) to 205 participants. This study designed, developed, as well as empirically tested the PAWSTM mobile app that alerted and warned participants to the signs of phishing in emails on mobile devices.FindingsThe results of this study indicated audio alerts and visual warnings potentially lower phishing susceptibility in emails. Audiovisual warnings appeared to assist study participants in noticing phishing emails more easily and in less time than without audiovisual warnings.Practical implicationsThis study's implications to mitigation of phishing emails are key, as it appears that alerts and warnings added to email applications may play a significant role in the reduction of phishing susceptibility.Originality/valueThis study extends the existing information security body of knowledge on phishing prevention and awareness by using audiovisual alerts and warnings to email recipients tested in real-life applications.
Additive manufacturing of powder components based on subtractive sintering approach
Authors: Carrillo Maricruz Henkel , Lee Geuntak , Maniere Charles , Olevsky Eugene A. 
Published: July 2021

Purpose
The purpose of this work is to introduce a novel approach of using additive manufacturing (AM) to produce dense complex ceramic and metallic parts. Powder 3D printing has been gaining popularity due to its ease of use and versatility. However, powder-based methods such as Selective Laser Melting (SLM) and Sintering (SLS), utilizes high power lasers which generate thermal shock conditions in metals and are not ideal for ceramics due to their high melting temperature. Indirect additive manufacturing methods have been explored to address the above issues but have proven to be wasteful and time-consuming.

Design/methodology/approach
In this work, a novel approach of producing high density net-shaped prototypes using subtractive sintering (SS) and solvent jetting is developed. AM combined with SS (AM-SS) is a process that includes five simple steps. AM-SS can produce repeatable and reliable results as has been shown in this work.

Findings
As a proof-of-concept, a zirconia dental crown with a high density of 97% is fabricated using this approach. Microstructure and properties of the fabricated components are analyzed.

Originality/value
A major advantage of this method is the ability to efficiently fabricate high density parts using either metal powder and more importantly, ceramic powder which is traditionally difficult to densify using AM. Additionally, any powder particle size (including nano) and shape can be used which is not the case for traditional powder-based 3D printing.
Desynchronised times? Chronobiology, (bio)medicalisation and the rhythms of life itself
Authors: Williams Simon J. , Meadows Robert , Coveney Catherine M. 
Published: July 2021

AbstractThis paper takes a critical look at the role of chronobiology in society today, with particular reference to its entanglements with health and medicine and whether or not this amounts to the (bio)medicalisation of our bodily rhythms. What we have here, we show, is a complex unfolding storyline, within and beyond medicine. On the one hand, the promises and problems of these circadian, infradian and ultradian rhythms for our health and well‐being are now increasingly emphasised. On the other hand, a variety of new rhythmic interventions and forms of governance are now emerging within and beyond medicine, from chronotherapies and chronopharmacology to biocompatible school and work schedules, and from chronodiets to the optimisation of all we do according to our ‘chronotypes’. Conceptualising these developments, we suggest challenges us to think within and beyond medicalisation to wider processes of biomedicalisation and the biopolitics of our body clocks: a vital new strand of chronopolitics today indeed which implicates us all in sickness and in health as the very embodiment of these rhythms of life itself. The paper concludes with a call for further research on these complex unfolding relations between chronobiology, health and society in these desynchronised times of ours.
The reification of concrete work in Egyptian film production
Authors: El Khachab Chihab 
Published: July 2021

AbstractThe anthropology of cinema has been instrumental in describing the ‘unseen’ labour invested in making films. What has been less explored is film workers’ erasure of each other's concrete effort in a similar manner. This process is what I call ‘reification’. Extending Georg Lukács's reflections, I argue that the relations of production throughout the film‐making process seem to be transformed into relations between things (images and sounds) in a recurring pattern. In Egypt, this transformation impacts every juncture in commercial film production, and film workers manage its continuous impact via conventional means of recognition towards their concrete work. The overarching project is to understand, on the one hand, how the serial erasure of concrete work contributes to creating the film as a commodity and, on the other hand, how workers find value in their work under conditions where their effort is consumed by the things that they produce.
Two community types occur in gut microbiota of large‐sample wild plateau pikas (Ochotona curzoniae)
Authors: YU Qiaoling , LI Guoliang , LI Huan 
Published: July 2021

AbstractStudies on large‐sample gut microbial sequencing data indicate that gut microbiota can be divided into multiple community types; different community types may influence the community function and ecosystem service. However, the knowledge on the classification, diversity, interaction, and assembling of microbial community types in the gut of wild animals is still insufficient. Here, we used pika gut microbiota data as an example to study the microbial community types in large‐sample sequencing dataset. Cecal microbial communities from 118 wild plateau pika (Ochotona curzoniae) individuals at 5 elevational regions on the Qinghai–Tibet Plateau were analyzed. Our results show that pika gut microbiota can be separated into 2 community types (Cluster I and Cluster II). Cluster I was mainly distributed on the high‐elevation regions with more than 3694 m and was most dominated by Firmicutes. Cluster II was from the low‐elevation areas (lower than 3580 m), and was predominated by Bacteroidetes. Cluster I had a higher community alpha‐diversity and predicted functional diversity than Cluster II, and the beta‐diversity and predicted functional profiles of these 2 clusters were significantly different. Network analysis revealed that there were more complex interactions between Cluster I, which had enhanced influence on the co‐occurrences of other microbes in the bacterial community when compared to Cluster II. Phylogenetic analysis found that the environmental filtering in the Cluster I was stronger than Cluster II. The assemblages of pika gut bacterial communities were determined mainly by deterministic processes, while the relative importance of deterministic processes accounted for more percentages in the Cluster I than Cluster II. Our results demonstrated that 2 gut microbial community types in pikas had distinct diversity patterns and ecological functions. Current methods are also helpful for identifying gut community types and the related mechanisms behind gut microbiota types in large‐sample sequencing data of wild animals.

Published: July 2021

AbstractBackgroundIn our previous study, we indicated that scutellarin (SCU) induced an anticancer effect in A549 cells. However, whether SCU regulates the radiosensitivity of non‐small cell lung cancer (NSCLC) and its related mechanism is still unclear.MethodsIn this study, we explored the anticancer effect induced by iodine‐125 (125I) and SCU at a sensitizing concentration in A549 and H1975 cells. Cellular apoptosis and proliferation were detected by flow cytometry, Bcl‐2/Bax expression level, cell cycle, CCK‐8, and EdU staining. A tumor model using nude mice was also carried out to investigate the combined effect of 125I and SCU in vivo. In addition, the expression level of AKT/mTOR pathway was detected to investigate whether it is linked to the anticancer effect of 125I and SCU.ResultsSCU at a sensitizing concentration promoted the 125I‐induced apoptosis and antiproliferative effect in A549 and H1975 cells. Moreover, the same results were obtained in vivo. Based on our findings, the AKT/mTOR pathway was significantly downregulated after combined treatment with 125I and SCU.ConclusionsThe results of our study suggested that SCU promotes the anticancer effects induced by 125I in NSCLC cells by downregulating the AKT/mTOR pathway and lays a foundation for future application of this combined treatment.
A decline in planned, but not spontaneous, preterm birth rates in a large Australian tertiary maternity centre during COVID‐19 mitigation measures
Authors: Gallo Linda A. , Gallo Tania F. , Borg Danielle J. , Moritz Karen M. , Clifton Vicki L. , Kumar Sailesh 
Published: July 2021

BackgroundReports from around the world suggest that rates of preterm birth decreased during COVID‐19 lockdown measures.AimsTo compare the prevalence of preterm birth and stillbirth rates during COVID‐19 restriction measures with infants born at the same maternity centre during the same weeks in 2013–2019.Materials and MethodsDeidentified data were extracted from the Mater Mothers’ healthcare records database. This is a supra‐regional tertiary perinatal centre. Logistic regressions were used to examine singleton live preterm birth rates during the beginning of COVID‐19 restrictions (16 March‐17 April; ‘early’; 6955 births) and during the strictest part of COVID‐19 restrictions (30 March‐1 May; ‘late’; 6953 births), according to gestational age subgroups and birth onset (planned or spontaneous). We adjusted for multiple covariates, including maternal age, body mass index, ethnicity, parity, socioeconomic status, maternal asthma, diabetes mellitus and/or hypertensive disorder. Singleton stillbirth rates were also examined between 16 March–1 May.ResultsPlanned moderate/late preterm births declined by more than half during early COVID‐19 restrictions compared with the previous seven years (29 vs an average of 64 per 1000 births; adjusted odds ratio 0.39, 95% CI 0.22–0.71). There was no effect on extremely or very preterm infants, spontaneous preterm births, or stillbirth rates. Rolling averages from January to June revealed a two‐week non‐significant spike in spontaneous preterm births from late April to early May, 2020.ConclusionsTogether with evidence from other nations, the pandemic provides a unique opportunity to identify causal and preventative factors for preterm birth.
The evolution of perennially enlarged breasts in women: a critical review and a novel hypothesis
Authors: Pawłowski Bogusław , Żelaźniewicz Agnieszka 
Published: July 2021

ABSTRACTThe possession of permanent, adipose breasts in women is a uniquely human trait that develops during puberty, well in advance of the first pregnancy. The adaptive role and developmental pattern of this breast morphology, unusual among primates, remains an unresolved conundrum. The evolutionary origins of this trait have been the focus of many hypotheses, which variously suggest that breasts are a product of sexual selection or of natural selection due to their putative role in assisting in nursing or as a thermoregulatory organ. Alternative hypotheses assume that permanent breasts are a by‐product of other evolutionary changes. We review and evaluate these hypotheses in the light of recent literature on breast morphology, physiology, phylogeny, ontogeny, sex differences, and genetics in order to highlight their strengths and flaws and to propose a coherent perspective and a new hypothesis on the evolutionary origins of perennially enlarged breasts in women. We propose that breasts appeared as early asHomo ergaster, originally as a by‐product of other coincident evolutionary processes of adaptive significance. These included an increase in subcutaneous fat tissue (SFT) in response to the demands of thermoregulatory and energy storage, and of the ontogenetic development of the evolving brain. An increase in SFT triggered an increase in oestradiol levels (E2). An increase in meat in the diet of earlyHomoallowed for further hormonal changes, such as greater dehydroepiandrosterone (DHEA/S) synthesis, which were crucial for brain evolution. DHEA/S is also easily converted to E2 in E2‐sensitive body parts, such as breasts and gluteofemoral regions, causing fat accumulation in these regions, enabling the evolution of perennially enlarged breasts. Furthermore, it is also plausible that after enlarged breasts appeared, they were co‐opted for other functions, such as attracting mates and indicating biological condition. Finally, we argue that the multifold adaptive benefits of SFT increase and hormonal changes outweighed the possible costs of perennially enlarged breasts, enabling their further development.
Young citizen sensors for managing large carnivores: Lessons from 40 years of monitoring a brown bear population

Published: July 2021

AbstractLarge carnivores encounter various threats from human activities. Population trend detection among carnivore species and implementation of management policies based on monitoring are urgently needed for human–carnivore coexistence. We demonstrate how young citizens have helped reveal long‐term trends in brown bear field sign detection rates following a government policy change (i.e., abolishment of the spring cull). We used a 40‐year dataset of field signs collected by volunteer college students in northern Japan and analyzed the resulting data using state‐space models. The spring cull had a significant negative impact on the number of grids with field signs; the detection rate under spring cull pressure declined from 19 to 0% between 1976 and 1990. However, abolishment of the spring cull in 1990 had a significant positive effect on the number of grids with field signs; the detection rate increased from 0 to 13% between 1991 and 2015, suggesting that the government policy change strongly affected the threatened brown bear population. Structured monitoring schemes, simplicity and/or attractiveness in monitoring targets may ensure the data quality and duration of citizen‐based monitoring. These findings suggest a high potential for engaging college students in developing sustainable monitoring of large carnivore populations and in supporting wildlife management.
The assets’ pledgeability channel of unconventional monetary policy
Authors: Ferrero Giuseppe , Loberto Michele , Miccoli Marcello 
Published: July 2021

AbstractWe identify a new channel of the monetary policy transmission that affects asset prices through the secured interbank market. Central bank’s open market operations, by changing the relative amount of securities and reserves, alter the amount of securities that can be used as collateral and, consequently, influence their prices. Ceteris paribus the magnitude of the effect depends on assets’ pledgeability properties (haircuts). We analyze the relation between yields of euro area government bonds, the haircuts applied to these assets and the relative amount of bonds and central banks reserves. The empirical evidence confirms that this channel is economically relevant.
