Published: September 2021

Introduction:
Delayed cord clamping (DCC) has numerous benefits to the neonate, including increased hemoglobin levels, decreased need for red blood cell transfusions, and decreased incidence of necrotizing enterocolitis and intraventricular hemorrhage. A preliminary observational study at our institution demonstrated 12% of the observed deliveries met the DCC standard, defined as umbilical cord clamping at least 30–60 seconds after birth. Therefore, we designed a quality improvement project to increase the percentage of deliveries using DCC.

Methods:
We planned a quality improvement project aiming to increase DCC rates on the university obstetrics service. Our interventions included provider education, installation of timers in the delivery suites, and modification to documentation in the electronic health record. We measured our results through the documented status of cord clamping, either: (1) greater than or equal to 30 seconds or (2) less than 30 seconds. We analyzed the DCC rates weekly and compared those results to the DCC goal of 80% of all deliveries.

Results:
Postintervention DCC rates were 96% overall. Rates of DCC met our aim of 80% or greater each of the 6 weeks we collected data.

Conclusion:
Simple and inexpensive interventions quickly led to improvements in DCC rates on our university obstetrics service. Our interventions including, provider education, installation of timers in delivery suites, and modification to cord clamping documentation in the electronic health record can be easily instituted at other hospitals. Additionally, the simplicity of this system can produce long-term sustainability of DCC.

AbstractObjectivesTo describe the real-world data on the effectiveness of Pfizer-BioNtech BNT162b2 and AstraZeneca-Oxford AZD1222 vaccines against COVID-19 in a large cohort in the Kingdom of Saudi Arabia (KSA).MethodsA total of 18,543 subjects received a single-dose of either of the vaccines at one vaccination centre in KSA, and were followed up for three to eight months. Clinical data from medical records, adverse events (AEs) from a self-reporting system, and COVID-19 infection data from the national databases were retrieved and analysed.ResultsSubjects median age was 33 years old with an average of 27.3 body mass index and the majority were male (60.1%). 92.17% of the subjects had no COVID-19 infection post-vaccination. Diabetes mellitus (p=0.0325), organ transplantation (p=0.0254), and morbid obesity (p=0.0014) were risk factors for infection post-vaccination. Unlike vaccine type, being Saudi, male, or obese was more likely to get the infection earlier. AE reports from 1084 subjects included injection site pain, fatigue, fever, myalgia, headache.ConclusionSingle-dose COVID-19 vaccines in KSA showed an effectiveness rate of 92.17% up to eight months follow-up. The rate for AZD1222 was higher than what have been previously reported. Side effects and AEs were within what has been reported in clinical trials.
Haemosporidian infection does not alter aerobic performance in the Pink-sided Junco (Junco hyemalis mearnsi)

Published: September 2021

ABSTRACTAvian haemosporidia are blood parasites that can have dramatic fitness consequences on their hosts, including largescale population declines when introduced to naïve hosts. Yet the physiological effects that accompany haemosporidian infection and underlie these fitness decrements are poorly characterized in most wild birds. Because haemosporidia destroy host red blood cells and consume host hemoglobin, they are predicted to have detrimental impacts on avian blood-oxygen transport and, as a result, reduce aerobic performance. However, the documented effects of infection on avian hematological traits vary across species and no effects have been demonstrated on avian aerobic performance to date. Here we quantified the physiological effects of haemosporidian infections on wild ‘Pink-sided’ Juncos (Junco hyemalis mearnsi) breeding in northwestern Wyoming, USA. We assayed hematological traits (hemoglobin concentration and hematocrit) and aerobic performance (resting and summit metabolic rates, thermogenic endurance, and aerobic scope), then screened individuals for haemosporidian infectionpost-hoc(n= 106 adult juncos). We found that infection status did not correlate with any of the physiological indices that we measured, suggesting there is little cost of haemosporidian infection on either junco aerobic performance or energy budgets. Our results highlight the need for more studies of haemosporidia infections in a broader range of species and in a wider array of environmental contexts.
Elucidating spatially-resolved changes in host signaling during Plasmodium liver-stage infection

Published: September 2021

AbstractUpon transmission to the human host, Plasmodium sporozoites exit the skin, are taken up by the blood stream, and then travel to the liver where they infect and significantly modify a single hepatocyte. Low infection rates within the liver have made proteomic studies of infected hepatocytes challenging, particularly in vivo, and existing studies have been largely unable to consider how protein and phosphoprotein differences are altered at different spatial locations within the heterogeneous liver. Using digital spatial profiling, we characterized changes in host signaling during Plasmodium yoelii infection in vivo without disrupting the liver tissue, and measured variation between infected cells. Moreover, we measured alterations in protein expression around infected hepatocytes and identified a subset of CD163+ Kupffer cells that migrate towards infected cells during infection. These data offer the first insight into the heterogeneity of the infected hepatocyte in situ and provide insights into how the parasite may alter the local microenvironment to influence its survival and modulate immunity.
Structure and mechanism of the γ-glutamyl-γ-aminobutyrate hydrolase SpuA from Pseudomonas aeruginosa

Published: September 2021

Polyamines are important regulators in all living organisms and are implicated in essential biological processes including cell growth, differentiation and apoptosis. Pseudomonas aeruginosa possesses an spuABCDEFGHI gene cluster that is involved in the metabolism and uptake of two polyamines: spermidine and putrescine. In the proposed γ-glutamylation–putrescine metabolism pathway, SpuA hydrolyzes γ-glutamyl-γ-aminobutyrate (γ-Glu-GABA) to glutamate and γ-aminobutyric acid (GABA). In this study, crystal structures of P. aeruginosa SpuA are reported, confirming it to be a member of the class I glutamine amidotransferase (GAT) family. Activity and substrate-binding assays confirm that SpuA exhibits a preference for γ-Glu-GABA as a substrate. Structures of an inactive H221N mutant were determined with bound glutamate thioester intermediate or glutamate product, thus delineating the active site and substrate-binding pocket and elucidating the catalytic mechanism. The crystal structure of another bacterial member of the class I GAT family from Mycolicibacterium smegmatis (MsGATase) in complex with glutamine was determined for comparison and reveals a binding site for glutamine. Activity assays confirm that MsGATase has activity for glutamine as a substrate but not for γ-Glu-GABA. The work reported here provides a starting point for further investigation of polyamine metabolism in P. aeruginosa.
A cohesive model of predicting tax evasion from the perspective of fraudulent financial reporting amongst small and medium sized enterprises
Authors: Ngah Zainal Abidin , Ismail Norashikin , Abd Hamid Nadiah 
Published: September 2021

Purpose
The issue of tax evasion through fraudulent financial reporting committed by companies is a major concern facing the tax authority in Malaysia. As such, the purpose of this study is to propose a cohesive model of predicting tax evasion from the perspective of fraudulent financial reporting amongst small- and medium-sized enterprise (SME) taxpayers.

Design/methodology/approach
The proposed model for this study is designed to explore the extent of the relationships between the independent variables: family ownership firms, company size, presence of tax professionals, company’s duration in business and frequency of tax audits and the moderating variable, i.e. tax audit officers’ level of competence; and the dependent variable, i.e. tax evasion from the perspective of fraudulent financial reporting. This study is grounded on four theories: agency theory, political cost theory, economic deterrence theory and competency theory. Data will be gathered from actual audit cases resolved by the Inland Revenue Board of Malaysia. Ordinary least square regression analysis is proposed for the investigation.

Findings
This study anticipates that family ownership firms, company size, presence of tax professionals, company’s duration in business and frequency of tax audits could be associated with tax evasion amongst SMEs in Malaysia. This study further proposes that highly competent tax audit officers could mitigate the relationship between frequency of tax audits and tax evasion practices amongst SMEs in Malaysia.

Originality/value
This study should be able to provide a cohesive model of predicting tax evasion from the perspective of fraudulent financial reporting amongst SMEs in Malaysia. Research on fraudulent financial reporting amongst SMEs is very limited, especially involving the level of competence of the tax audit officers; therefore, this study should contribute to the tax evasion literature by providing a comprehensive model of predicting tax evasion through fraudulent financial reporting using a Malaysian tax setting.
Successful family business succession: Utilizing peer groups for critical leadership skills development
Authors: Wittmer Jenell Lynn-Senter , Longenecker Clinton Oliver , Jones Angie 
Published: September 2021

Purpose
The current study explores the necessary leadership skills required for leadership succession in family businesses as well as best development activities for each skill. The current study provides suggestions for best practices in developing and utilizing peer groups as a leadership development method.

Design/methodology/approach
A needs assessment was conducted by surveying 150 family-business leaders. Leaders were asked, “What are your most pressing leadership development needs for your organization as you move toward succession? A follow-up question was then asked: “For each of these skills, what method would best help develop this skill for family business leaders?” The responses were content analyzed, placed into themes, and rank ordered.

Findings
High agreement amongst business leaders was found as eight leadership skills were cited by high percentages of family-business leaders. Leaders overwhelmingly reported peer developmental activities as being the best method for developing these skills.

Originality/value
Succession planning in family-businesses is critical as many family business fail to make it past the first or second generation. However, little research explores what specific leadership skills are necessary for optimal succession. As well, many leaders in public organizations seek individual methods of development, such as executive coaching, whereas family business leaders seek group activities to learn with/through their peers.
Improved particle swarm optimization for mean-variance-Yager entropy-social responsibility portfolio with complex reality constraints
Authors: Deng Xue , Lin Yingxian 
Published: September 2021

PurposeThe weighted evaluation function method with normalized objective functions is used to transform the proposed multi-objective model into a single objective one, which reflects the investors' preference for returns, risks and social responsibility by adjusting the weights. Finally, an example is given to illustrate the solution steps of the model and the effectiveness of the algorithm.Design/methodology/approachBased on the possibility theory, assuming that the future returns of each asset are trapezoidal fuzzy numbers, a mean-variance-Yager entropy-social responsibility model is constructed including piecewise linear transaction costs and risk-free assets. The model proposed in this paper includes six constraints, the investment proportion sum, the non-negativity proportion, the ceiling and floor, the pre-assignment, the cardinality and the round lot constraints. In addition, considering the special round lot constraint, the proposed model is transformed into an integer programming problem.FindingsThe effects of different constraints and transaction costs on the effective frontier of the portfolio are analyzed, which not only assists investors to make decisions close to their expectations by setting appropriate parameters but also provides constructive suggestions through the overall performance of each asset.Originality/valueThere are two improvements in the improved particle swarm optimization algorithm: one is that the complex constraints are specifically satisfied by using a renewable 0–1 random constraint matrix and random scaling factors instead of fixed ones; the other is eliminating the particles with poor fitness and randomly adding some new particles that satisfy all the constraints to achieve the goal of global search as much as possible.

Published: September 2021

Purpose
Hotel industry is witnessing a radical change as a result of technology interaction such as artificial intelligence (AI) in service tasks. As a result of this transformation, the pattern of service delivery based on human interaction has been changed to digital interaction. This brought opportunities to the hotels industry and consolidate its competitive advantage. However, the understanding gap still existed in both practical implementation and literature, especially in developing countries. Therefore, this paper aims to explore how hotels use AI to carry out services tasks.

Design/methodology/approach
The authors adopted the qualitative research method through Semi interviews. The sample was purposively selected from five 5-star hotels in the UAE, meanwhile, the managers were the targeted respondents.

Findings
Through content analysis, the authors find that the UAE hotels use AI in managing trip planning, reception service and room services. The authors also find that there are four key drivers that improve the performance of AI, which include AI infrastructure flexibility, strategic alignment, management and skills. Finally, the authors found four indicators of the impact of AI on hotels, which are quality, cost and market share and customers satisfaction.

Originality/value
This study is one of few studies that explored the use of AI in the hotels industry and discussed how AI influence several aspects of hotels performance and helped them to attain their competitive advantage. This study is also one of few studies and the first study in UAE to explore the key drivers of AI performance in UAE hotels.
Factors influencing Jamaican householders’ housing choice
Authors: Jackson Anetheo , Archer Carol Dean 
Published: September 2021

PurposeThe purpose of this paper is to bridge the gap in knowledge of Jamaican householders’ housing choices and to provide empirical research that will support the inclusion of the householders’ perspectives in developing housing policies and programmes in Jamaica.Design/methodology/approachA questionnaire survey of 430 householders drawn from public housing developments in 6 of 14 parishes in Jamaica was conducted. A pragmatic approach was taken in this study. As such, both qualitative and quantitative data were used to investigate the factors influencing householders’ housing choices. The data were analysed using exploratory factor analysis to extract the main factors influencing the householders’ housing choices.FindingsThe research revealed that the dwelling features and its environment, accessibility and neighbourhood attributes are three factors influencing householders’ housing choice. Notably, the dwelling and its immediate environment explained the majority of the variance in housing choice. This suggests that if householders are given a choice between a larger more desirable dwelling in a clean, safe and well-maintained community and housing with proximity to work, job opportunities, urban services and other proximity variables, they are less likely to choose the latter.Research limitations/implicationsThe factors obtained from this study provide some insights into the scale of preference of the household heads and desired attributes of affordable housing solutions. They also shed some light on what might have caused some past affordable housing solutions to be undesirable. In addition to this, there is some intuition that there may be efficacy in adopting a community development approach to housing. These results have strong implications for housing planning. However, given the island’s challenge with the proliferation of squatter settlements, it is recommended that further research, which includes these householders’ be carried out.Originality/valueThis research is the first to examine the views of Jamaican householders’ with the purpose of understanding what influences their choice of housing. The findings provide new insights into the trade-off that householders may be willing to make in choosing their housing. The results provide a source of reference in reviewing the performance of past policies and programmes.

Authors: Yang Lu , Huo Baofeng , Gu Minhao 
Published: September 2021

PurposeThis study looks beyond firm boundaries to depict supply chain (SC) adaptability and classifies it into internal, customer and supplier dimensions to investigate their performance implications, respectively. This study also examines the enablers of SC adaptability based on information processing theory.Design/methodology/approachThis study applies the structural equation modeling method to investigate relationships among SC information sharing, SC adaptability and operational performance using data collected from 216 manufacturers in China.FindingsInternal information sharing has a positive impact on three dimensions of SC adaptability, whereas supplier and customer information sharing only have a positive impact on supplier adaptability. Customer and supplier information sharing interact to positively influence the three dimensions of SC adaptability, while internal and customer information sharing interact to negatively affect customer adaptability. We also find that all the three dimensions of SC adaptability can enhance operational performance.Originality/valueThis study contributes to providing a holistic definition of SC adaptability and classifies it into three dimensions. It also investigates antecedents and performance outcomes of SC adaptability.

Published: September 2021

Purpose
The fundamentals of Lean are applicable and can be used in any industry, even non-profit and government organizations, however, there might be certain limitations due to the nature and the specifics of the industry. This study aims to explore what barriers of Lean implementation textile manufacturers might encounter. The authors consider the problem is worth to be explored for the potential to improve the effectiveness of Lean implementation in textile sector companies.

Design/methodology/approach
This research was conducted by using qualitative content analysis with open coding of the selected literature followed by empirical research in a Latvian textile manufacturing company.

Findings
The presented literature review shows Lean implementation barriers and critical success factors in various industries. The findings from the case study can be divided into two groups. The first confirmed the barriers already identified in the previous research. The second identified industry specific implementation barriers that were not recognized in the related literature.

Research limitations/implications
The original research was limited in scope to one Latvian textile manufacturer, therefore future studies on the subject to confirm the outcome of the research are required.

Originality/value
There is a limited number of studies on the application of Lean in the textile and apparel industry. The literature on Lean implementation in the Latvian manufacturing sector is also limited. The results of this research may have a practical application for textile manufactures considering implementing Lean in their processes.
Fashion supply chain transparency: do as I say not as I do
Authors: Muratore Adriana Pigeard , Marques Leonardo 
Published: September 2021

PurposeFashion brands are under heavy criticism for often exhibiting poor working conditions and producing environmental damage. Pressure comes from initiatives such as Fashion Transparency Index (FTI) by Fashion Revolution to assess fashion brands' transparency based on information publicly disclosed. But an understanding of how such movements reflect in a Global South country characterised by institutional voids is still absent.Design/methodology/approachWhile the FTI ranks individual brands, in this study the authors have analysed 305 documents extracted from the websites of 20 Brazilian fashion brands to unpack practices and re-bundle them according to three archetypes – opaque, translucent and transparent – that display a maturity curve.FindingsThe authors show that advancement is heterogeneous, and we complement previous research exposing the limits of an NGO in driving transparency by investigating a context embedded in institutional voids. The authors show that most fashion brands restrict transparency to tier-1 suppliers. Moreover, although fashion brands increasingly demand disclosure from their suppliers, they do not clarify their own purchasing practices such as cancellation and payment policies. On the positive note, the authors show that maturity for transparent brands can include the actionability concept by engaging with consumer via surveys and educative content.Originality/valueThe authors contribute to theory by offering a maturity curve of fashion supply chain transparency. The authors contribute to practice by offering the three archetypes – opaque, translucent and transparent. This study unveils heterogeneity and asymmetry between the levels of transparency that buying firms demand from their suppliers against what they provide about their own practices.
