Published: July 2023

AbstractThe morphological transformation of the pectoral/shoulder girdle is fundamental to the water-to-land transition in vertebrate evolution. Although previous studies have resolved the embryonic origins of the tetrapod shoulder girdle, those of the fish pectoral girdle remain uncharacterized, creating a gap in the understanding of girdle transformation mechanisms from fish to modern tetrapods. Here, we identified the embryonic origins of the pectoral girdle of zebrafish (Danio rerio), including the cleithrum as an ancestral pectoral girdle element lost in extant tetrapods. Our combinatorial approach of photoconversion and genetic cell lineage tracing mapped that cleithrum development combines three adjoining embryonic populations: cranial neural crest cells and lateral plate mesoderm-derivatives (trunk lateral plate mesoderm and cardiopharyngeal mesoderm-associated cells). The topographical position of the cleithrum at the head/trunk interface is a shared characteristic among cleithrum-bearing fish, thus its multiple embryonic origins are likely a conserved feature. Moreover, a comparison of the pectoral girdle progenitors between aquatic fish and extant amniotes suggests that cleithrum loss is associated with the disappearance of its unique developmental environment by the insertion of the neck lateral plate mesoderm into the head/trunk interface. Overall, our study establishes an embryological framework for pectoral/shoulder girdle formation and their evolutionary trajectories from their origin in water to diversification on land.

AbstractThe study of transcription factors that determine specialised neuronal functions has provided invaluable insights into the physiology of the nervous system. Peripheral chemoreceptors are neurone-like electro-physiologically excitable cells that link the oxygen content of arterial blood to the neuronal control of breathing. In the adult, this oxygen chemosensitivity is exemplified by the Type I cells of the carotid body and recent work has revealed one isoform of the transcription factor HIF, HIF-2α, to have a non-redundant role in the development and function of that organ. Here we show that the activation of HIF-2α, including isolated overexpression alone, is sufficient to induce oxygen chemosensitivity in the otherwise unresponsive adult adrenal medulla. This phenotypic change in the adrenal medulla was associated with retention of extra-adrenal paraganglioma-like tissues that resemble the foetal organ of Zuckerkandl and also manifest oxygen chemosensitivity. Acquisition of chemosensitivity was associated with changes in the adrenal medullary expression of classes of genes that are ordinarily characteristic of the carotid body, including G-protein regulators and atypical subunits of mitochondrial cytochrome oxidase. Overall, the findings suggest that, at least in certain tissues, HIF-2α acts as a phenotypic driver for cells that display oxygen chemosensitivity, providing a route to mechanistic understanding.
Safety risk assessment of aircraft EWIS based on the improved combined weight and cloud model
Authors: Sang YiQin , Li Huang , Ge Hongjuan , Gao Cong , Hu Yinxiao , Jin Hui 
Published: July 2023

Purpose
This study aims to conduct the aircraft electrical wiring interconnection system (EWIS) safety risk assessment process abundantly and hierarchically and establish the assessment index system considering the weights and interrelationships of different levels of indices.

Design/methodology/approach
Due to the failure of EWIS being multifactorial, hidden and diverse, this paper divides the factors influencing the failure of EWIS into 3 primary indices, 13 secondary indices and 38 tertiary indices. Taking open circuit failure (OCF) and short circuit failure (SCF) as examples, calculate the weights of assessment indices based on the triangular fuzzy number analytic hierarchy process (TFNAHP) and triangular fuzzy number decision-making trial and evaluation laboratory (TFNDEMATEL). The cloud model (CM) divides the risk levels and obtains the safety risk assessment results. The comparative analyses of different weight calculation methods, different failure modes and different aircraft EWIS zones verify the effectiveness and practicability of the proposed method.

Findings
The results show that the proposed method aligns more with the actual situation than other methods. Also, the results identify key focus objects in EWIS safety risk assessment, such as the surrounding environmental factors among the primary indices having the most significant influence on OCF and SCF, the risk level of SCF being higher than that of OCF, etc.

Originality/value
This paper proposes a safety risk assessment index system for aircraft EWIS based on the cable parameters, surrounding environmental factors, installation and protection methods. The weight assignment is added to the assessment index system, and the safety risk assessment model is constructed by combining TFNAHP, TFNDEMATEL and CM.
Determination of heavy metals in cow's and buffalo's fresh raw milk from different areas of Pakistan
Authors: Abid Kanza , Shams Zafar Iqbal , Tahir Muhammad Suleman , Zubair Arif 
Published: July 2023

PurposeThe presence of heavy metals in milk causes many acute and chronic physiological dysfunctions in human organs. The present study aims to investigate the heavy metals in cow's and buffalo's milk of two major cities, Karachi and Gujranwala, Pakistan to estimate metal intake by humans from this source.Design/methodology/approachIn total, 48 milk samples from 2 cities were drawn from animals' udder to avoid contamination. Each sample was digested with nitric acid at 105 oC (degree Celsius) on a pre-heated electric hot plate to investigate the metals by atomic absorption spectroscopy (flame type). Air-acetylene technique analyzed chromium, cadmium and lead, and the hydride method analyzed arsenic in the milk samples.FindingsThe results revealed the highest mean lead concentration (19.65 ± 43.86 ppb) in the milk samples, followed by chromium (2.10 ± 2.33 ppb) and arsenic (0.48 ± 0.73 ppb). Cadmium was not detected in any sample, assuming cadmium's occurrence was below the detection level. The concentrations of all the metals in the samples of the two cities do not differ statistically. Lead concentrations in the buffalo's milk were higher than in cow's milk (p < 0.05). However, the concentrations of arsenic and chromium between buffalo's and cow's milk do not differ statistically. The present study reveals a lower level of metals in the milk than those conducted elsewhere. The mean concentrations of all the metals met the World Health Organization's (WHO) safety guidelines (1993).Research limitations/implicationsAlthough cadmium causes toxicity in the human body, cadmium could not be measured because cadmium's concentration was below the detection level, which is 1 ppb.Practical implicationsThis study will help reduce the toxic metals in our environment, and the sources of heavy metals, particularly from the industrial sector could be identified. The feed and water consumed by the milking animals could be carefully used for feeding them.Social implicationsThis study will help reduce the diseases and malfunction of human organs and organ systems since these heavy metals cause toxicity and carcinogenicity in humans. Arsenic and chromium cause cancer while lead causes encephalopathy (a brain disease).Originality/valueThe study reports heavy metal concentrations in the two attributes of four independent variables of raw milk samples that were scarcely reported from Pakistan.

Published: July 2023

PurposeThe COVID-19 pandemic has generated a crisis that has hit the European economy and the currently existing systems. To cope with the crisis, Europe has started an investment aiming the energy transition and crisis. Portugal, Spain and Greece have received the approval of their National Recovery Plans from the European Commission, with a definition of spending up to 2026 through the European Union (EU) Next Generation Found. The study investigates whether the Green Deal policies are relaunched by the plans financed and whether the pandemic has changed and conditioned the priorities of the energy transaction. The study uses the lens of corporate social responsability (CSR) and relapse measurable across the Sustainable Development Goals (SDGs).Design/methodology/approachThe Green Deal policies supported by new European investments in the three countries were analyzed through a content analysis (CA) technique to investigate the associated practical and theoretical elements.FindingsThe energy theme has a relevance compared to other issues in the investment plans envisaged in Greece, Portugal and Spain. The analysis highlights energy efficiency, sustainable energy and reduction of consumption among the main themes. Energetically, sustainable building plays a central role. The study highlights the relationship between Green Deal policies, CSR, SDGs and management tools adopted.Originality/valueThe study strengthens the relationship between the Green Deal, CSR and SDGs by identifying policies that have already been implemented and theoretical and practical gaps on which politicians and scholars will have to investigate and support in the process of development and continuity of the identified pillars.

Authors: Rabelo Anaile , Rodrigues Marcos W. , Nobre Cristiane , Isotani Seiji , Zárate Luis 
Published: July 2023

Purpose
The purpose of this study is to identify the main perspectives and trends in educational data mining (EDM) in the e-learning environment from a managerial perspective.

Design/methodology/approach
This paper proposes a systematic literature review to identify the main perspectives and trends in EDM in the e-learning environment from a managerial perspective. The study domain of this review is restricted by the educational concepts of e-learning and management. The search for bibliographic material considered articles published in journals and papers published in conferences from 1994 to 2023, totaling 30 years of research in EDM.

Findings
From this review, it was observed that managers have been concerned about the effectiveness of the platform used by students as it contains the entire learning process and all the interactions performed, which enable the generation of information. From the data collected on these platforms, there are improvements and inferences that can be made about the actions of educators and human tutors (or automatic tutoring systems), curricular optimization or changes related to course content, proposal of evaluation criteria and also increase the understanding of different learning styles.

Originality/value
This review was conducted from the perspective of the manager, who is responsible for the direction of an institution of higher education, to assist the administration in creating strategies for the use of data mining to improve the learning process. To the best of the authors’ knowledge, this review is original because other contributions do not focus on the manager.
Housing reconstruction after traumatic events: a Poe study of Bam housing after the 2003 earthquake, Iran
Authors: Asadi Saeedeh , Sharghi Ali , Mottaki Zoheir , Salehsedghpour Bahram 
Published: July 2023

Purpose
Earthquake stressful events cause many consequences and need for survivors. Housing reconstruction is one of the most urgent needs; due to traumatic experiences, dialectical changes in people–place relationships occur.

Design/methodology/approach
The present study uses the Poe method and Q methodology to identify the hidden dimensions of trauma-informed housing reconstruction. A questionnaire with 74 items on the Likert scale was developed based on indicative Poe. It was completed by the purposive sampling method by Bam households. The influential factors in housing reconstruction with a psychological recovery approach were extracted by q-factor analysis in communities with different traumatic experiences.

Findings
According to the findings, first, people who had experienced complete home destruction; severe physical injuries; loss of family members and relatives; and were trapped under the earthquake rubble have different place-based needs in housing reconstruction for coping with fears and environmental concerns, protective behaviors, safety perception and as result safety reassurance. Second, regardless of the traumatic experience and losses, reconstruction acceleration and economic-social dignity have a positive effect on the communities’ psychological recovery.

Originality/value
It is noteworthy that housing reconstruction with a psychological recovery approach has two basic aspects. Although some independent factors of traumatic experiences will be efficient in this approach, it was found that the type of earthquake traumatic experiences will also be effective in the survivors’ place-based needs and biases.
Organizational communication strategies in response to major disruptions: the case of the worsening situation in the Russia-Ukraine conflict
Authors: Gurkov Igor , Dahms Sven 
Published: July 2023

Purpose
The purpose of this paper is to understand communication strategies formed by multinational subsidiaries in a transition economy during disruptive events. The authors develop and test a framework based on political realism and situational crisis communication theory (SCCT).

Design/methodology/approach
The authors collect and analyze communication statements from multinational subsidiaries located in Russia and made in the first two months (March–April, 2022) of the Russia–Ukraine conflict.

Findings
This study’s main findings are twofold. First, this study extends SCCT by showing that multinational subsidiaries use communication strategies that go beyond the traditional categories of diminish, rebuild and bolster. In particular, this study identifies so-called “shut the door” and “burning bridges” methods as possible industrial and home country contingent communication strategies. Second, this study shows that possession of a political realism lens provides us with powerful communication strategies made requisite during disruptive events.

Practical implications
The results provide practical hands-on advice for subsidiary managers on how to communicate effectively and efficiently during disruptive events such as the one described. This study offers novel communication strategies that help to understand the wider implications for managers in both home and host countries.

Originality/value
To the best of the authors’ knowledge, this is one of the first papers to apply SCCT and political realism to a current disruptive event for multinational enterprises, i.e. the ongoing Russia–Ukraine conflict. In that context, this study expands both perspectives by highlighting their complementarities and their conceptual boundaries. The authors can base those insights on two unique and purpose-built databases of multinational subsidiary characteristics in Russia-proper.
Green supplier governance and firm performance: a comprehensive understanding of three governance approaches
Authors: Liu Junjun , Chen Yuan , Zhu Qinghua 
Published: July 2023

PurposeThis study aims to develop a comprehensive green supplier governance (GSG) concept and explore whether specific GSG approaches (green supplier assessment, green supplier assistance and green strategic partnership with suppliers (GSPS)) bring environmental and economic performance. Moreover, this study aims to reveal a synergistic effect of three GSG approaches on performance improvement.Design/methodology/approachUsing data collected from 200 Chinese manufacturing firms, regression analysis was employed to reveal the relationship between specific GSG approaches and firm performance. Further, cluster analysis was used to identify groupings of firms regarding implementation levels of three GSG approaches and compare the performance of the firm groups.FindingsGreen supplier assessment (GSA) can bring environmental performance, but GSA is not associated with economic performance. Green supplier assistance is positively associated with economic performance, while green supplier assistance cannot improve environmental performance. Only GSPS leads to improvement for both environmental and economic performance. Furthermore, firms with high implementation levels of GSA and GSPS (whether with high or low implementation levels of GSAS) can achieve the best environmental and financial performance.Practical implicationsThis study provides implications for firms to more strategically and comprehensively implement GSG approaches, which can be more effective in bringing environmental and economic performance.Originality/valueThe authors' study extends the GSG concept with two approaches by subdividing the collaborative approach into green supplier assistance and GSPS based on the collaboration levels. This study also sheds light on how to improve firm performance by different GSG approaches and reveals a synergistic effect of three GSG approaches on performance.
Assessing the current sustainability initiatives of Canadian SME restaurants
Authors: Robinson Emily , Gordon Rebecca , McAdams Bruce 
Published: July 2023

PurposeThe purpose of this study is to investigate what sustainability initiatives are being implemented by Canadian independent restaurants and to determine if the initiatives represent all 10 categories of a sustainable restaurant as established by a sustainability initiative framework.Design/methodology/approachThe study uses a qualitative approach of semi-structured interviews with 15 small to medium enterprise (SME), independent restaurant owners and operators across Canada. The data was digitally transcribed and thematic analysis was performed.FindingsResults indicated that most initiatives aligned with the categories of “sustainable food/menu” and “waste reduction and disposables” which shows that the operators were inclined to pursue initiatives in customer view. Restaurants put limited focus on water supply, chemicals and pollution reduction, furniture and construction materials. Some of the barriers to implementing, measuring and learning about initiatives were: cost, lack of access to programs, supply chain complications, not having buy-in from owners and lack of time to implement.Practical implicationsThe study recommends that governments provide incentives to implement sustainability initiatives that are out of sight to the customer. For example, implementing composting, energy efficient equipment and water saving processes. It is also recommended that third-party restaurant organizations provide more accurate, evidence-based guidance and education on implementing a wide-range of sustainability initiatives.Originality/valueThis research contributes to the literature on sustainability in restaurants and applies a sustainability initiative framework in a practical context. The study provides a unique assessment of the current state of restaurant sustainability and states where restaurants need to improve their efforts.
#FeesMustFall# movement in the post-apartheid era: legitimacy battle for leaders
Authors: du Plessis Linda , Bui Hong T.M. 
Published: July 2023

PurposeUnderpinned by institutional legitimacy, this study explores how South African public university senior managers struggled to maintain legitimacy during an unplanned radical change process.Design/methodology/approachGioia's grounded theory analysis approach is employed to analyse interviews with 37 senior managers of public-funded universities in South Africa.FindingsThis study's findings show that a change without proper planning severely damages institutions in all aspects of leadership's normative, empirical, moral and pragmatic legitimacy.Research limitations/implicationsThis study contributes to the literature on legitimacy by illustrating the importance of institutional legitimacy during unplanned social change and the factors that negate legitimacy.Originality/valueThough other legitimacy models have been well developed, they do not apply to such unplanned social change in organisations. This study shows a different angle of the legitimacy crisis under unplanned social change conditions.
Multiresponse optimization in amylolytic desizing of viscose fabric in the copresence of ferrous ions and an anionic surfactant
Authors: Raza Zulfiqar Ali , Rehman Aisha , Anwar Faiza , Ahmad Naseer 
Published: July 2023

Purpose
This study aims to investigate the effect of the copresence of ferrous (Fe2+) ions and sodium dodecyl sulfate (SDS) on the activity of an amylase enzyme during the desizing of greige viscose fabric for potential industrial applications. The removal of starches is an essential step before processing the fabric for dyeing and finishing operations. The authors tend to accomplish it in eco-friendly and sustainable ways.

Design/methodology/approach
The experiments were designed under the Taguchi approach, and the results were analyzed using grey relational analysis to optimize the process. The textile properties of absorbency, reducing sugars, bending length, weight loss, Tegawa rating and tensile strength were assessed using the standard protocols. The control and optimized viscose specimens were investigated for certain surface chemical properties using advanced analytical techniques including scanning electron microscopy (SEM), X-ray diffraction (XRD) and thermal gravimetric analysis (TGA).

Findings
The results demonstrate that the Fe2+ concentration and process time were the main influencing factors in the amylolytic desizing of viscose fabric. The optimized process conditions were found to be 0.1 mm Fe2+ ions, 3 mm SDS, 80°C, 7 pH and 30 min process time. The copresence of Fe2+ ions and SDS promoted the biodesizing of viscose fabric. The SEM, Fourier transform infrared spectroscopy, XRD and TGA results demonstrated that the sizing agent has efficiently been removed from the fabric surface.

Practical implications
The amylase desizing of viscose fabric in the presence of certain metal ions and surfactants is a significant subject as the enzyme may face them due to their prevalence in the water systems. This could also support the biodesizing and bioscouring operations to be done in one bath, thus making the textile pretreatment process both economical and environmentally sustainable.

Originality/value
The authors found no report on the biodesizing of viscose fabric in the copresence of Fe2+ ions and the SDS surfactant under statistical multiresponse optimization. The biodesized viscose fabric has been investigated using both conventional and analytical approaches.
