Drivers of genetic differentiation and recent evolutionary history of an Eurasian wild pea
Authors: Hellwig Timo , Abbo Shahal , Ophir Ron
Published: June 2021

Genetic diversity a major determinant for the capacity of species to persist and adapt to their environments. Unraveling the factors affecting genetic differentiation is crucial to understand how genetic diversity is shaped and species may react to changing environments. We employed genotyping by sequencing to test the influence of climate, space, latitude, altitude and land cover on genetic differentiation in a collection of 81 wild pea samples (Pisum sativumssp.elatius) from across its distribution range from western Europe to central Asia. We also attempted to elucidate the species recent evolutionary history and its effect on the current distribution of genetic diversity. Association of single SNPs with climate variables were analyses to test for signatures of local adaptation. Genetic variation was geographically structured into six distinct genetic cluster. Two of which were associated with a taxonomic group (Pisum sativumssp.humile) that according to some researchers does not qualify for a sub-species rank due to its alleged lack of genetic distinctness from other conspecific groups. The effect of the tested factors influencing genetic differentiation were rather variable among genetic clusters. The climate predictors were most important in all clusters. Land use was more important in clusters from areas strongly influenced by human land use, especially by agriculture. We found a statistically significant association of 3,623 SNPs (2.4 % of all SNPs) with one of the environmental predictors. Most of them were correlated with latitude followed by temperature, precipitation and altitude. Estimation of SNP effects of the candidates resulted in a missense to silent ratio of 0.45, suggesting many of the observed candidates SNPs may alter the encoded amino acid sequence. Wild peas went through a genetic bottleneck during the last glacial period followed by population recovery. Probably associated with this population recovery, we detected a range expansion, which may have led to an eastward range expansion of the European cluster to Turkey and thereof southwards and eastwards. Overall, the interplay of several environmental factors and the recent evolutionary history affected the distribution of genetic diversity in wild peas where each subpopulations were differently affected by those factors and processes.
Effect of rust inhibitors and surface strengthening materials on service life of marine RC structures
Authors: Zhu Haiwei , Yu Hongfa , Ma Haiyan , Da Bo , Mei Qiquan
Published: June 2021

Purpose

The purpose of this paper is to compare the effect of rust inhibitors and surface strengthening materials on the service life of RC structures in tropical marine environments and ultimately to provide basis and recommendations for the durability design of reinforced concrete (RC) structures.

Design/methodology/approach

Slag concrete specimens mixed with four kinds of rust inhibitors and coated with four kinds of surface strengthening materials were corroded by seawater exposure for 365 days, and the key parameters of chloride ion diffusion were obtained by testing. Then a new service life prediction model, based on the modified model for chloride ion diffusion and reliability theory, was applied to analyze the effect of rust inhibitors and surface strengthening materials on the service life of RC structures in tropical marine environments.

Findings

Rust inhibitors and surface strengthening materials can effectively extend the service life of RC structures through different effects on chloride ion diffusion behavior. The effects of rust inhibitors and surface strengthening materials on the service life extension of RC structures adhered to the following trend: silane material > cement-based permeable crystalline waterproof material > hydrophobic plug compound > spray polyurea elastomer > water-based permeable crystalline waterproof material > calcium nitrite > preservative > amino-alcohol composite.

Originality/value

Using a new method for predicting the service life of RC structures, the attenuation law of the service life of RC structures under the action of rust inhibitors and surface strengthening materials in tropical marine environments is obtained.

Authors: Mantovani Ribeiro Daielly Melina Nassif , Hourneaux Junior Flavio , Lara Cunha Cristiana Lara , Kaetsu Patricia Taeko , Dionizio-Leite Patricia Fernanda , Machado Junior Celso
Published: June 2021

Purpose

This paper aims to discuss the role of information and communication technologies (ICTs) in the effective assessment of the sustainable development goals (SDGs) related to smart and sustainable city initiatives.

Design/methodology/approach

The study is based on a systematic review of the literature within the Web of Science and Scopus databases, comprising the studies about ICTs related to smart and sustainable city initiatives and sustainable assessment.

Findings

The main results point out that there are several different ways of assessing SDGs performance related to ICTs use in smart and sustainable city initiatives. However, the effectiveness of these assessments can be questioned. The intensive use of technology understood as the core of smart and sustainable cities does not imply an improvement in sustainability unless these technologies are strategically addressed to underpin those objectives. Moreover, not all SDGs have considered the use of ICTs in their targets.

Research limitations/implications

The scope of the study is limited to “how” the information is used and managed, rather than analysing the sustainable performance itself. As a limitation, the findings and conclusions do not consider other sources of studies, such as grey literature.

Practical implications

This study suggests some requirements for providing better and more reliable sustainable assessment, making smart and sustainable city initiatives more correlated with the SDGs.

Social implications

By acknowledging the difficulties associated with SDGs assessment, concerning the municipal level, the study offers valuable insights into the effectiveness of public policies and public management. Besides, the findings shed some light on if and how the use of ICTs can effectively enhance sustainable development issues.

Originality/value

This study offers valuable contributions to the literature by providing a collection of insights regarding how the ICTs may genuinely lead to a sound assessment of sustainable development, especially regarding the SDGs.
Empirically validating five propositions regarding 3D visualizations for subsurface utility projects
Authors: van Manen Mechiel , olde Scholtenhuis Léon , Voordijk Hans
Published: June 2021

Purpose

This study aims to empirically validate five propositions about the benefits of three-dimensional (3D) visualizations for the management of subsurface utility projects. Specifically, the authors validate whether benefits from 3D in the literature of building construction project management also apply to subsurface utility projects and map them using a taxonomy of project complexity levels.

Design/methodology/approach

A multiple case study of three utility construction projects was carried out during which the first author was involved in the daily work practices at a utility contractor. 3D visualizations of existing project models were developed, and design and construction meetings were conducted. Practitioners' interactions with and reflections on these 3D visualizations were noted. Observational data from the three project types were matched with the five propositions to determine where benefits of 3D visualizations manifested themselves.

Findings

Practitioners found that 3D visualizations had most merit in crowded urban environments when constructing rigid pipelines. All propositions were validated and evaluated as beneficial in subsurface utility projects of complexity level C3. It is shown that in urban projects with rigid pipelines (project with the highest complexity level), 3D visualization prevents misunderstanding or misinterpretations and increases efficiency of coordination. It is recommended to implement 3D visualization approaches in such complex projects

Originality/value

There is only limited evidence on the value 3D visualizations in managing utility projects. This study contributes rich empirical evidence on this value based on a six-month observation period at a subsurface contractor. Their merit was assessed by associating 3D approaches with project complexity levels, which may help utility contractors in strategically implementing 3D applications.
A sobering examination of how the COVID-19 pandemic exacerbates the disparities of vulnerable populations
Authors: Williams Lilcelia A.
Published: June 2021

Purpose

Intersectionality theory is a social justice theory customarily employed to address inequities which arise in the academic or legal arenas as it relates to race and gender. The application of intersectionality theory extends beyond the convergence of multiple social identities. It provides an invaluable framework to examine the convergence of social identities, the social determinants of health and a global pandemic in communities of historically marginalized and underrepresented persons. The purpose of this paper is to examine how the coronavirus pandemic has exacerbated the disparities experienced by African American and Latinx persons using the principles of intersectionality theory as the schema.

Design/methodology/approach

A literature review was performed on the scholarly articles examining the disproportionate incidence and mortality rates of African Americans and Latinx persons in America.

Findings

The current literature confirms that the disparities which existed prior to the onset of the coronavirus pandemic have been magnified by systemic oppression and racism of historically marginalized and underrepresented persons in America. The coronavirus pandemic has spotlighted the disparities in sustainable employment and access to health care for African American and Latinx persons.

Originality/value

Employing a social justice theoretical framework of intersectionality provides an opportunity to examine the lived experiences of African American and Latinx persons without race/ethnicity being the primary focal point. Future research will illustrate the urgent need for public health policy reform to eradicate the disparities experienced by African American and Latinx populations.

Authors: Muiambo Cláudia C.E. , Joao Isabel M. , Navas Helena V.G.
Published: June 2021

Purpose

The purpose of this paper is to make a lean assessment of a chemical analyst training laboratory in a higher education institution and identify the main types of waste on a daily basis and understand the lean maturity of the laboratory and establish priority areas of intervention to make the laboratory leanest.

Design/methodology/approach

A single descriptive case study methodology was used to carry out the lean laboratory evaluation. The lean manufacturing waste terminology was adapted to a lean analytical laboratory environment, and a lean waste assessment step-by-step procedure was developed to reach the study goal.

Findings

Three types of waste (i.e. transport, waiting and defects) were the main contributors of the problem. The Pareto analysis results showed that 37.5% of the different types of waste contributed to almost 51.4% of the problems. The case study allowed on diagnosing wastes, understanding the lean maturity in a teaching laboratory setting and priority areas of intervention

Practical implications

Some data collection methods were used, and tools were developed to answer the research questions. A waste measurement instrument was created to evaluate lean waste in a chemical analytical laboratory, and a lean classification scheme was built to understand the lean maturity of the laboratory. The lessons learnt of the lean assessment in a teaching laboratory and the developed tools will be helpful for future research and for practitioners in a teaching chemical analytical laboratory setting.

Originality/value

The number of lean assessment studies in teaching laboratories is not very significant, and this work contributes to overcome this gap illustrating the lean waste assessment foundation with a step-by-step procedure and tools used in a teaching laboratory to perform a lean assessment and identify opportunities for improvement. A generic roadmap to lean laboratory waste assessment and continuous improvement is proposed with the key elements to take into consideration.
Service workers and “difficult customers”: quality challenges at the front line
Authors: Gal Iddo , Yagil Dana , Luria Gil
Published: June 2021

Purpose

The purpose of this paper is to contribute to the literature on service quality and value co-creation and co-destruction by unpacking the phenomenon described as “difficult customers”, which has many associated costs for service organizations. The paper examines how frontline service employees make sense of and react to client behaviors that disrupt service processes.

Design/methodology/approach

This is a qualitative study with 128 frontline workers, who were interviewed about their perceptions, explanations and reactions to problem-related customers, using a sensemaking perspective.

Findings

Content analysis revealed 17 themes related to workers' perceptions, explanations and reactions to problem-related customers. Workers classify behaviors of problem-related customers in terms exceeding the single notion of intentionality that dominates the literature, instead referring to the degree of both controllability and malevolence of customers. Service workers choose a wide range of behavioral reactions that have not been studied before.

Research limitations/implications

A convenience sample, although large, limits generalizability. Suggestions for future quantitative research are proposed.

Practical implications

Based on the findings, the authors suggest specific directions related to managerial policy and organizational practices related to training and employee empowerment and service recovery routines.

Originality/value

The study introduces a new theoretical notion of “problem-related customers”, set within a value co-creation context. It presents findings that enable deeper understanding of the emotional and behavioral reactions of frontline workers to service disruptions and offers multiple scholarly contributions, new research directions and managerial insights that can help to improve service recovery and service quality
Recasting urban imaginaries: politicized temporalities and the touristification of a notorious Mexico City barrio
Authors: Dürr Eveline , Acosta Raúl , Vodopivec Barbara
Published: June 2021

Purpose

The purpose of this paper is to point to the significance of temporally charged imaginaries of neglected places and their residents in the context of slum tourism research. It examines the way in which tour guides draw on specific temporalities to recast the poverty and stigma of the Mexico City barrio of Tepito and thus design narratives to alter long-held imaginaries of this neighbourhood.

Design/methodology/approach

Two tours are analysed through an anthropological lens using ethnographic methods. Authors took part in the tours, registering the guides’ discourse and interventions, as well as the places and situations observed. The insights of this paper stem from the empirical evidence and reveal how diverse imaginaries are enacted through tour guiding.

Findings

Without necessarily following a single, coherent narrative, tour guides link different moments in time to simultaneously generate and contest slum tour imaginaries. The guides in this case study not only challenge existing stereotypes, but also critically engage political neglect while showcasing Tepito’s potentiality. Even so, the analysed tours seek to recast the barrio as integral to Mexico City’s history and future.

Originality/value

Until now, the importance of temporalities in the generation of imaginaries in slum tourism research has gained only little attention. The case study presented here show how alternative forms of tourism are offering unconventional readings of urban neighbourhoods. These processes, the authors argue, help not only re-imagine disadvantaged districts, such as Tepito, but also to re-think the city as a whole in terms of its past, present and future.
Corporate sustainability performance in the emerging market of Turkey: the role of accounting information quality and firm risk
Authors: Kalash Ismail
Published: June 2021

Purpose

The purpose of this study is to investigate the effect of accounting information quality (AIQ) and firm risk on the corporate sustainability performance (CSP) of Turkish listed firms.

Design/methodology/approach

This study used data of 70 firms listed on Istanbul Stock Exchange during the period 2014–2019. Binary and ordinal logistic regression models are used to examine the factors affecting CSP as proxied by the membership to BIST Sustainability Index.

Findings

The results of this research indicate that AIQ is negatively related to CSP in firms with severe agency problem. The results also show a significant negative relationship between accounting earnings volatility and CSP. However, the effect of stock return volatility on CSP is not significant. Furthermore, the findings reveal that the possibility of being a member of Turkish sustainability index is higher for larger firms, firms that are included in BIST Corporate Governance Index and firms with high leverage, more research and development (R&D) intensity and high brand value.

Practical implications

The results of this study provide implications for policymakers, investors and firms about the role of firm characteristics in determining CSP.

Originality/value

To the author's knowledge, this study is the first to explore the effect of AIQ and firm risk on CSP in the Turkish context.
Lessons learned: what the COVID-19 global pandemic has taught us about teaching, technology, and students with autism spectrum disorder
Authors: Roitsch Jane , Moore Robert L. , Horn Annemarie L.
Published: June 2021

Purpose

The purpose of this paper is to examine the impact of the abrupt transition from attending school face-to-face to participating in online learning in response to the COVID-19 pandemic as reported by a parent of a student with autism spectrum disorder (ASD).

Design/methodology/approach

A phone interview was conducted with the parent of a child with ASD. The semi-structured interview focused on how the child’s family was impacted when classes shifted to virtual from face-to-face learning in response to the COVID-19 pandemic.

Findings

A total of four themes emerged from the interview. Three of these included adjustments to changes in routines and roles, instruction, and social interactions. A final theme involved the benefits and challenges that emerged following the transition to online learning for students with ASD. While we are in an unprecedented time with the COVID-19 global pandemic presenting understandable challenges, opportunities for and examples of effective virtual learning environments for students with ASD were reported in the parent interview and supported by the literature.

Practical implications

This research provides insight regarding the impact of COVID-19 and highlights elements that should be considered involving technology for students with ASD. Increased awareness regarding the benefits and contraindications of technology while teaching students with ASD can minimize the adverse effects and enhance the positive impact of technology in students with ASD.

Originality/value

This paper shares the experiences of one parent of a child with ASD and their experiences with technology and learning during COVID-19.
Consumer perception vs sensory assessment of the quality of clothes of selected brands available on the Polish market
Authors: Salerno-Kochan Renata , Turek Paweł
Published: June 2021

Purpose

The aim of the study reported in this article was to establish whether the quality of clothes of a given brand is perceived and assessed by consumers at the same level. An additional purpose was to identify the features that characterize the quality of popular, among Polish young female consumers, clothing brands and to classify them according to their quality level (perceived and assessed).

Design/methodology/approach

The article presents two approaches to consumer assessment of the quality of clothes: the survey method, in which the product quality was determined by 320 Polish female young respondents (19–25) based on their own previous experiences and impressions related to a particular clothing brand, and a direct assessment of shirts of selected brands using a sensory quality assessment method, a five-point hedonic scale with the verbal anchor (115 evaluators).

Findings

The research has revealed a significant difference between the perception of selected quality features of brands and the consumer assessment of the products. The perception maps developed based on the PROFIT analysis (PROperty FITting) as well as on cluster analysis provided interesting information about the situation of selected brands and their features in comparison with others and allowed to identify strong and weak features characterizing a given category.

Research limitations/implications

This study has several limitations. First and foremost, the research results cannot be generalized to all consumers because they encompass the results from one national context and one population of respondents (young females). It should also be noted that the conducted research comprises only the most popular clothing brands available on the Polish market, in particular, the fast fashion segment brands. Furthermore, it would be advisable to carry out a sensory assessment of the quality of other clothing items offered under the brand names investigated.

Practical implications

This research could be a valuable source of information for clothing company managers, thanks to which they could better manage their brand and its position on the market. When undertaking marketing activities consisting of building positive perceptions about the product, it is important to make sure that the product offers an attractive sensory experience. When real quality deviates from consumer perceptions about the quality, managers should take corrective actions to restore and even improve the brand image in the eyes of the consumer, as well as to ensure the brand and the products offered under it a stable position on the market.

Originality/value

By comparing two approaches to consumer quality assessment, discrepancies between declared and real (sensory) quality of clothes have been identified and the distinctive features that differentiate selected brands regarding their quality level have been indicated.
Humanitarian logistics and supply chain standards. Literature review and view from practice
Authors: Paciarotti Claudia , Piotrowicz Wojciech D. , Fenton George
Published: June 2021

Purpose

The paper is focused on standards in humanitarian logistics and supply chain. Standards, implemented between organisations, allow improving the interoperability of humanitarian operations. The paper aims (1) to review a state-of-the-art approach to the topic by the academic community, (2) to evaluate the current use of standards among humanitarian organisations and (3) to investigate the perceived need for further and specific standards.

Design/methodology/approach

To achieve the aims, the literature was reviewed; then a survey on 227 professionals from the humanitarian logistics sector was conducted.

Findings

Based on 227 responses, it is possible to conclude that most surveyed professionals recognise the need for and the importance of standardisation in humanitarian logistics, especially in areas such as procurement, distribution, medical logistics and logistics planning, which were perceived as critical areas that require standardisation.

Research limitations/implications

Practitioners and scholars were targeted via social media, through mailing lists and via communication from the practitioner organisation – the Humanitarian Logistics Association (HLA). While it provided good access to different groups of respondents, the response rate is not possible to calculate.

Practical implications

The findings confirm the high importance of standardisation, indicating areas and functions that should be standardised first. Standardisation may improve cooperation between different humanitarian actors, allowing better service provision for beneficiaries. Thus there are also potential negative impacts, i.e. impact on localisation, which should be overcome.

Social implications

Results do not have a direct social impact; however, they stimulate research and work among practitioners on standardisation, which in turn could improve cooperation between humanitarian actors, thereby enabling a better humanitarian response in emergencies.

Originality/value

The majority of papers on standardisation use a qualitative approach. This paper applies a survey among a large network of humanitarian practitioners, capturing their view on the topic and perception of the need for standardisation. The work is descriptive; however, it could be used as a base for further studies related to humanitarian standards.
Innovation and small and medium enterprises’ performance in Cameroon
Authors: Ndzana Martin , Cyrille Onomo , Mvogo Gregory , Bedzeme Thierry
Published: June 2021

Purpose

This article attempts to explain performance through the development of innovations within small and medium enterprises (SMEs). Specifically, the authors analyse the determinants of innovation and assess the role of technological and non-technological innovations in performance.

Design/methodology/approach

Based on a sample of 508 Cameroonian SMEs, the PSM (propensity score matching) technique was used to reduce the selection bias inherent in this type of analysis.

Findings

The results show that technological innovation does not influence significantly the performance of SMEs, whereas non-technological innovation positively influences it. The combination of these two types of innovation leads to better performance than even accentuated development of only one type.

Practical implications

To improve the performance of SMEs, it is necessary to adopt a comprehensive innovation policy that combines non-technological and technological innovations. In addition, it is important to intensify informations and communication technologies (ICT) promotion policies that contribute to the adoption of innovations within enterprises.

Originality/value

This paper contributes to the literature by showing the role of technological and non-technological innovations in explaining the performance of SMEs. Moreover, unlike the existing work in sub-Saharan Africa, which is limited to testing the innovation–performance relationship, this study also determines the productivity gain generated by innovative firms compared to non-innovative ones.
COVID-19 and necessity-based online entrepreneurship education at US community colleges
Authors: Liguori Eric W. , Winkler Christoph , Zane Lee J. , Muldoon Jeff , Winkel Doan
Published: June 2021

Purpose

This paper explores community college entrepreneurship education's near-instantaneous transition to online course delivery following the 2020 COVID-19 pandemic.

Design/methodology/approach

Primary data were obtained from 92 community college entrepreneurship faculty via online survey in late March of 2020, right at the time faculty were required to transition their courses to an online mode of delivery due to the COVID-19 pandemic. Data were collected in partnership with the National Association for Community College Entrepreneurship and the Entrepreneurship Education Project.

Findings

While the majority of community college entrepreneurship educators have taught online previously, many were not familiar with exemplar education technology tools and applications, demonstrating an opportunity for continued professional development. To deliver courses online, educators primarily relied on pre-recorded lectures and using Zoom as the technology platform of choice. Last, there were significant faculty concerns about their ability to effectively create an “experiential” classroom virtually for students to learn and practice entrepreneurship.

Originality/value

This is the first paper investigating how community college entrepreneurship educators responded to one of the most disruptive events to ever impact entrepreneurship education (viz. the COVID-19 pandemic). More broadly, this is also one of very few studies exploring both (1) community college entrepreneurship education and (2) how unexpected crises (e.g. natural disasters, pandemics) impact educational environments.
An adaptive thermal comfort model for naturally ventilated classrooms of technical institutions in Madurai
Authors: S. Subhashini , Kesavaperumal Thirumaran , Noguchi Masa
Published: June 2021

Purpose

Occupants dwelling in hot climatic regions of India for a longer term are tolerable to high temperature levels than predicted by American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) standards. The purpose of this study is to evaluate the thermal sensations (TS) and neutral temperature of the occupants in naturally ventilated (NV) and air-conditioned (AC) classrooms of two technical institutions located in the same premises in the suburbs of Madurai. The main focus of this study is to understand the occupants’ behaviour in response to the thermal conditions of the educational buildings particularly in the warm and humid climatic zone of Madurai.

Design/methodology/approach

This research collected data through field studies. The data included 383 survey questionnaires from NV classrooms and 285 from AC classrooms, as well as on-site measurements of interior and exterior weather conditions. The TS results show that the students preferred well-designed NV classrooms than AC classrooms. A new adaptive comfort equation derived from this study can be applied to NV classrooms in warm and humid climates where mean outdoor temperature exceeds 40°C.

Findings

The neutral temperature derived for NV classrooms in Madurai ranged from 29°C to 34°C. Thus, the occupants in the NV classrooms of the higher learning educational institutions in the warm and humid climatic region of Madurai can adapt well to higher indoor temperature levels than predicted by ASHRAE comfort levels with minimum adjustments.

Research limitations/implications

The study was limited to only occupants in two premier higher learning technical educational institutions located in Madurai region within 5–10 km within the city limits to understand the implications of microclimate with respect to the urban context. Thus, further research is required to examine the tendency under local conditions in other regions beyond those applied to this study.

Social implications

The findings of this study showed that occupants in higher learning educational intuitions in Madurai prefer NV classrooms than AC classrooms. Therefore, with rising demands of energy use for mechanical ventilation and the associated high cost for running AC buildings, architects should prioritize the design of energy efficient buildings through the optimal use of passive design strategies for ventilation and thermal comfort. This study gives a base data for architects to understand the adaptive limitations of occupants and design NV buildings that can promote natural ventilation and provide better thermal environments that can help increase the productivity of students.

Originality/value

This paper was an attempt to develop the adaptive comfort model for NV classrooms in Madurai regions. There has been no attempt to identify the adaptive comfort levels of occupants in higher learning technical educational institutions located in warm and humid climatic region of India.

Perceived HRM practices and organizational citizenship behaviours: a case study of a Chinese high-tech organization
Authors: Huang Jie , He Liguo
Published: June 2021

Purpose

The purpose of this case study is to test a moderated mediation model linking employees' perceived HRM practices to organizational citizenship behaviours (OCB) with perceived insider status as the mediator and emotional exhaustion as the moderator in a Chinese high-tech organization.

Design/methodology/approach

A sample of 417 Chinese employees were recruited from a large Chinese high-tech company to participate in a paper-and-pencil survey, and mediation and moderation were analysed using PROCESS macro for SPSS.

Findings

Perceived insider status partially mediates the relationship between perceived HRM practices and OCB, and emotional exhaustion moderates the relationship between perceived insider status and OCB such that the strength of the relationship is stronger in employees with low emotional exhaustion levels than in employees with high emotional exhaustion levels.

Practical implications

There is a need for organizations to promote the physical and psychological well-being of its employees in order to maximize the effectiveness of HRM practices.

Originality/value

This case study provides novel insights into how employees' perceived HRM practices elicit OCB and its boundary conditions in collectivistic cultures.
Thermal property analysis of tri layer composite fabric towards the utility of sleeping bag
Authors: Kumar B. Senthil , T. Murugan
Published: June 2021

Purpose

This paper aims to investigate on composite fabrics to develop the improved sleeping bag using trilayered textile structures. A thermal comfort analysis of fabrics is essential to design an enhanced type of sleeping bag.

Design/methodology/approach

In this study, optimizing thermal and permeability properties of different combinations of trilayer composite fabrics was done. The inner layer was 100% wool-knitted single jersey fabric. The middle layer was polyester needle punched non-woven fabric. The outermost layer was nylon-based Core-Tex branded waterproof breathable fabric. Five variations in wool-knitted samples were developed by changing the loop length and yarn count to optimize the best possible combination. Two different polyester non-woven fabrics have been produced with the changes in bulk density. Twelve trilayer composite fabric samples have been produced, and thermal comfort properties such as thermal conductivity, thermal absorptivity, thermal resistance, air permeability and relative water vapour permeability have been analysed.

Findings

Among the 12 samples, one optimized sample has been found with the specification of 100% wool with 25 Tex yarn linear density having 4.432-mm loop length inner-layered fabric, 96 g/m2polyester nonwoven fabric as the middle layer, and 220 g/m2Nylon-Core tex branded outermost layer. All the functional properties of the composite fabric are significantly different with the knitted wool fabrics and polyester nonwoven fabrics, which have been confirmed by analysis of variance study.

Originality/value

This research work supports for producing sleeping bag with enhanced comfort level.
Applying knowledge, social concern and perceived risk in planned behavior theory for tourism in the Covid-19 pandemic
Authors: Rahmafitria Fitri , Suryadi Karim , Oktadiana Hera , Putro Heru Purboyo H. , Rosyidie Arief
Published: June 2021

Purpose

The paper aims to examine the effect of physical distancing control on the intention to travel during the pandemic and to assess the influence of knowledge, social concern and perceived risk on the theory of planned behavior (TPB).

Design/methodology/approach

A total of 1,068 Indonesian respondents through a purposive sampling approach, filled out online questionnaires during the pandemic. The collected data were analyzed using partial least squares-structural equation modeling.

Findings

The results indicated that subjective norm as the external factor of the TPB has a stronger effect than the internal factors; attitude and behavioral control. It appears that in a collectivist society, prohibition enforced by family and friends, as well as the government’s sanctions have a stronger influence on one’s decision to travel. The findings also suggested that knowledge, perceived risks and social concern effect tourists’ behavior. Uncertainty and inadequate knowledge will decrease the level of perceived risk, which leads to lower control in practicing physical distancing and increasing intention to travel during the pandemic.

Research limitations/implications

The research has limitations in its use of a convenient sampling method. This method may not represent the whole population, causing the results to be difficult for generalization. There is also the need for extending the TPB model with different variables in the context of tourism and pandemic. This study enriches the existing tourism literature by applying TPB to examine tourists’ behavior during the Covid-19 pandemic, focusing on knowledge, social concern and perceived risk theory.

Practical implications

This paper offers useful insights for tourism planners in the government and private destination management levels. It is crucial for a destination management organization to understand the relationship between knowledge, perception and social concern with tourists’ behavior while traveling during pandemics. The understanding of tourist’s behavior when traveling during the pandemic will assist in developing and creating activities and designing health protocols at tourist attractions.

Originality/value

This study extended the TPB to analyze tourists behavior during the pandemic by applying knowledge, social concern and perceived risk elements.
Legal Perception and Finance: The Case of IPO Firm Value

Published: June 2021

In this paper, we contribute to the literature on institutional determinants of IPO valuation. We introduce the concept of ‘legal signalling’, which focuses on the perception of the quality of law and thus complements the existing institutional approaches to IPO valuation which consider the quality of the positive law (‘standard view’) and firm‐level corporate governance practices (‘firm signalling view’). Our approach explicitly models the difference between the effect of the positive law and the effect of the perception of law on IPO value. Based on a worldwide longitudinal dataset of IPO performance across a large number of countries, we find strong support for the claim that the perception of the quality of law is more important than its actual quality to explain post‐IPO firm value. This effect holds regardless of whether the law's quality is correctly perceived or misperceived. Overall, our findings underscore the need for a more sophisticated theorization of the ways in which law affects entrepreneurial finance.
Does assortative mating contribute to reproductive isolation among sympatric ecotypes of the wing‐dimorphic stonefly Zelandoperla fenestrata (Plecoptera: Gripopterygidae)?

Testing for reproductive isolation among sympatrically diverging lineages is a key prerequisite for understanding speciation processes. Recent genome‐wide studies of the wing‐dimorphic New Zealand stonefly Zelandoperla fenestrata have revealed evidence for ecological speciation among sympatric ecotype pairs, but the basis for their apparent reproductive isolation remains unclear. We conduct paired mating tests among co‐distributed Z. fenestrata ecotypes from southern South Island to test for prezygotic barriers contributing to their reproductive isolation and divergence. Experimental data reveal assortative mating among ecotypes, with strong differentiation in the duration of matings between matched‐ecotype pairs relative to non‐matched pairs. These findings add weight to the hypothesis that assortative mating can be a key mechanism facilitating rapid ecological speciation of sympatric ecotypes. Our study also represents the first documentation of mating behaviours in the Southern Hemisphere stonefly suborder Antarctoperlaria.

Background

Perinatal mental ill‐health is a global health priority. Mental health screening during pregnancy is a routine part of clinical practice in many public hospital obstetric services across Australia, but implementation in the private hospital system has lagged.

Aims

This study explored health professionals’ perspectives on the Pre‐admission Midwife Appointment Program (PMAP), an antenatal mental health screening program at the Mater Hospital, Sydney.

Materials and Methods

Nine midwives and three medical specialists participated in focus groups or individual interviews; key themes were determined using thematic qualitative analysis.

Results

Five major themes and three sub‐themes were identified: immediate benefits to women (identifying women at risk; referrals to support services; supporting and educating women); enhanced overall quality of care at the hospital; the dilemma of partners attending; factors that make the program successful; and recommendations for improvement.

Conclusions

Results will inform the implementation of antenatal mental health screening programs at other private hospitals across Australia.

Background

Although microvascular free flaps are often used to reconstruct maxillary defects, dentoalveolar rehabilitation is arguably less common despite its importance to midface function and aesthetics. The aim of this study is to review the contemporary management of maxillary defects in a single quaternary referral institution to identify factors that assist or impede dentoalveolar rehabilitation.

Methods

A retrospective review of maxillary reconstructions performed between February 2017 and December 2020 was performed. Patient characteristics, defect classification, operative techniques, complications and dentoalveolar outcomes were recorded.

Results

A total of 85 maxillary reconstructions were performed in 73 patients. Of the 64 patients where dental rehabilitation was required, 31 received a functional denture (48%) with 24 (38%) being implant‐retained. Significant predictors of successful rehabilitation included the use of virtual surgical planning (VSP; 86% vs. 25%, p < 0.001), preoperative prosthodontic assessment (82% vs. 21%, p < 0.001), prefabrication (100% vs. 40%, p = 0.002) and use of the zygomatic implant perforator flap technique (100% vs. 39%, p = 0.001). Preoperative prosthodontic consultation was associated with 21‐fold increase in the odds of rehabilitation (odds ratio 20.9, 95% confidence interval 6.54–66.66, p < 0.005).

Conclusion

Preoperative prosthodontic evaluation, VSP and reconstructive techniques developed to facilitate implant placement are associated with increased dental rehabilitation rates. Despite using an institutional algorithm, functional dentures are frequently prevented by factors including soft tissue constraints, disease recurrence and patient motivation.
