Widespread distribution of collagens and collagen-associated domains in eukaryotes
Authors: Linden Tess A. , King Nicole 
Published: October 2021

AbstractThe origin of collagen, the dominant structural component of metazoan extracellular matrix, has long been cited as a critical step in the evolution of metazoan multicellularity. While collagens were once thought to be found only in metazoans, scattered reports of collagen domains in Fungi, and more recently in close relatives of metazoans, have called into question whether collagens are truly unique to metazoans. Here, we take advantage of recently sequenced genomes and transcriptomes of diverse holozoans (the clade encompassing metazoans and their close relatives), as well as publicly available proteomes from diverse non-holozoan eukaryotes, to conduct a systematic search for collagen domains across eukaryotic diversity. We find that collagen domains are ubiquitous in choanoflagellates, the sister group of metazoans, and widespread across many other major eukaryotic taxa. Many predicted collagens in non-metazoans are comparable to metazoan collagens in length and proline content. Moreover, most are present in species that also encode putative prolyl 4-hydroxylase domains, suggesting that, like metazoan collagens, they may be stabilized through the hydroxylation of prolines. Fibrillar collagen and collagen IV appear to be unique to metazoans, and we posit that their ability to assemble into superstructures may have contributed to the origin of metazoan multicellularity.

AbstractEndovascular therapies for intracranial aneurysms requires animal models for testing the safety and effectiveness prior to translation to the clinic. Rabbits combined with the elastase and right common carotid artery (RCCA) ligation methods is currently a widely used animal model for endovascular device testing. However, the injection of elastase utilizing angiocatheters may potentially exerts adverse torque to the parent vessel and the optimal aneurysm creation period has not been well investigated. In this study, we present a modification to the elastase/RCCA-ligation method by replacing the angio-catheter with a butterfly catheter. Formation of saccular aneurysms was introduced in New Zealand white rabbits (n = 6), and were maintained for 2, 4 and 6 weeks. The formed aneurysms exhibited an elongated geometry and were stable during the study period. We found that the modification in the animal surgery procedure provides improved manipulation of the surgical area, prolonged injection of elastase, and effective degradation of the vascular elastic lamina. Compared to the traditional elastase/RCCA-ligation method, the present technique can more effectively reduce unwanted injury to the parent vessel and, therefore, improved stability of the vasculature for testing the efficacy of newly developed endovascular embolization devices.

ABSTRACTTroglomorphism— any morphological adaptation enabling life to the constant darkness of caves, such as loss of pigment, reduced eyesight or blindness, over-developed tactile and olfactory organs—has long intrigued biologists. However, inferring the proximate and ultimate mechanisms driving the evolution of troglomorphism in freshwater fish requires a sound understanding of the evolutionary relationships between surface and troglomorphic lineages. We use Restriction Site Associated DNA Sequencing (RADseq) to better understand the evolution of theSinocyclocheilusfishes of China. With a remarkable array of derived troglomorphic traits, they comprise the largest cavefish diversification in the world, emerging as a multi-species model system to study evolutionary novelty. We sequenced a total of 120 individuals throughout theSinocyclocheilusdistribution. The data comprised a total of 646,497⍰bp per individual, including 4378 loci and 67,983 SNPs shared across a minimum of 114 individuals at a given locus. Phylogenetic analyses using either the concatenated RAD loci (RAxML) or the SNPs under a coalescent model (SVDquartets, SNAPP) showed a high degree of congruence with similar topologies and high node support (> 95 for most nodes in the phylogeny). The major clades recovered conform to a pattern previously established using Sanger-based mt-DNA sequences, with a few notable exceptions. We now recognize six major clades in this group, elevating the blind cavefishS. tianlinensisand the micro-eyedS. microphthalmusas two new distinct clades due to their deep divergence from other clades. PCA plots of the SNP data also supports the recognition of six major clusters of species congruent with the identified clades based on the spatial arrangement and overlap of the species in the PC space. A Bayes factor delimitation (BFD) analysis showed support for 21 species, recognizing 19 previously described species and two putative new cryptic ones. Two species whose identities were previously disputed,S. furcodorsalisandS. tianeensis, are supported here as distinct species. In addition, our multi-species calibrated tree in SNAPP suggests that the genusSinocyclocheilusoriginated around 10.5 Mya, with most speciation events occurring in the last 2 Mya, likely favored by the uplift of the Qinghai-Tibetan Plateau and cave occupation induced by climate-driven aridification during this period. These results provide a firm basis for future comparative studies on the evolution ofSinocyclocheilusand its adaptations to cave life.
Reset and prescribed performance approach to spacecraft attitude regulation
Authors: Zhang Chengxi , Dong Peng , Leung Henry , Wu Jin , Shen Kai 
Published: October 2021

Purpose
This paper aims to investigate the attitude regulation for spacecraft in the presence of time-varying inertia uncertainty and exogenous disturbances.

Design/methodology/approach
The high gain approaches are typically used in existing researches for theoretical advantages, bringing better performance but sensitive to parameter selection, making the controller conservative. A reset-control policy is presented to achieve the spacecraft attitude control with easy control parameter tuning.

Findings
The reset-control policy guarantees satisfying control performance despite using performance tuning function and saturation function besides reducing the conservativeness of the controller, thus reducing the effort in tuning control parameters.

Originality/value
Notably, the adaptive function owns a reset mechanism, which is reset to a preset condition when the controlled variable crosses zero. The mathematical analysis also shows the system trajectory can converge to a set centered at the origin.

Authors: Long Pham Dinh , Hien Bui Quang , Ngoc Pham Thi Bich 
Published: October 2021

PurposeThis study focuses on analyzing the relation between money supply, inflation and output in Vietnam and China.Design/methodology/approachUsing the error correction model and the vector autoregression model (ECM and VAR) and the canonical cointegration regression (CCR), the study shows similar patterns of these variable relations between the two economies.FindingsThe study points out the difference in the estimated coefficients between the two countries with different economic scales. While inflation in Vietnam is strongly influenced by expected inflation and output growth, inflation in China is strongly influenced by money supply growth and output growth.Originality/valueTo the best of the authors’ knowledge, this is the first empirical and comparative research on the relation between money supply, inflation and output for Vietnam and China. The study demonstrates that the relationship between money supply, inflation and output is still true in case of transition economies.
International backpackers' experiences of precarious visa-contingent farmwork
Authors: Kossen Chris , McDonald Nicole , McIlveen Peter 
Published: October 2021

PurposeAustralia's agricultural industry has become highly dependent on young low-cost, overseas “working holiday” visa workers known as “backpackers”, who are notoriously subject to exploitative workplace practices. This study aimed to explore backpackers' experiences in terms of how job demands, job resources and personal resources influence their appraisals of working in agriculture.Design/methodology/approachIn-depth semi-structured interviews were used to explore the work experiences of N = 21 backpackers employed under the Australian Working Holiday visa (subclass 417). Data were analyzed by thematic analysis and organized in terms of job demands and resources.FindingsThis study revealed job demands commonly experienced by agricultural backpacker workers (e.g. precarity, physically strenuous work, low pay), and job resources (e.g. adequate training, feedback) and personal resources (e.g. attitude, language) that buffer the demands. The findings indicate that backpackers' appraisals of their experiences and performance decline when demands outweigh resources.Originality/valueThis study offers an emic perspective on the work of an understudied segment of the agricultural workforce. The findings have implications for improving work practices and policies aimed at attracting and retaining this important labor source in the future.

Published: October 2021

PurposeBased on the research, the authors identify how four key concepts in disaster studies—agency, local scale, memory and vulnerability—are interrupted, and how these interruptions offer new perspectives for doing disaster research from and for the South.Design/methodology/approachMeta-analysis of case studies and revision of past and current collaborations of authors with communities across Chile.FindingsThe findings suggest that agency, local scale, memory and vulnerability, as fundamental concepts for disaster risk reduction (DRR) theory and practice, need to allow for ambivalences, ironies, granularization and further materializations. The authors identify these characteristics as the conditions that emerge when doing disaster research from within the disaster itself, perhaps the critical condition of what is usually known as the South.Originality/valueThe authors contribute to a reflexive assessment of fundamental concepts for critical disaster studies. The authors offer research-based and empirically rich redefinitions of these concepts. The authors also offer a novel understanding of the political and epistemological conditions of the “South” as both a geography and a project.
Optimum design of two-material bending plate compliant devices
Authors: Romero Augusto 
Published: October 2021

PurposeThe purpose of this study is to explore the optimum design of bending plate compliant mechanisms subjected to pure mechanical excitations using topological-derivative-based topology optimization. The main objective is to design the reinforcement in a plate of base material.Design/methodology/approachThe optimum design is performed by means of a level-set representation method guided by topological derivatives. Kirchhoff and Reissner–Mindlin models are used to solve the linear bending plate problem. A qualitative comparison has been carried out between the optimal obtained topologies for each model.FindingsThe proposed methodology was able to design reinforcement in a plate of the base material. The obtained reinforcements notably improve the device’s behavior. The shape and topology of the reinforcements vary depending on the mechanical plate model considered. In fact, in the Reissner–Mindlin solutions, very thin flexo-torsional hinges connecting big zones of the reinforcement material are designed.Originality/valueUp to date, the synthesis of ortho-planar mechanisms by means of continuum topology optimization was only boarded within a multi-physics context. In this work, the optimal design of pure ortho-planar compliance actuators is addressed. The best performance is found by analyzing the results for two classical mechanical plate models.

Authors: Adekoya Clement Ola 
Published: October 2021

Purpose
The need for sustainable development (SD) of higher education (HE) is recognized in the UN 2030 Agenda for SD. Central to the SD of HE is information literacy and information use. This study aims to investigate information literacy, information use and SD of HE in Nigeria.

Design/methodology/approach
A descriptive survey research design was used for the study. The population for the study was the staff of public higher educational institutions in Southern Nigeria. A self-structured online questionnaire was sent to the respondents via social media. The data generated were analysed using mean, frequency count and percentages.

Findings
It was reflected that information literacy played a significant role in the SD of HE and that the extent of information use was high. It was revealed that the areas of HE that require SD include economic/finance and investment priorities; administration, mission and planning; and research and scholarship.

Originality/value
The study emphasizes that SD of HE in the current educational enterprise requires that people are information literate and information is extensively used.

Authors: Ram Mangey , Tyagi Subhi , Kumar Akshay , Goyal Nupur 
Published: October 2021

PurposeThe purpose of this paper is to design a ring network topology system and alter it into a series–parallel type framework. Then, reliability of the framework is analysed and authors also discussed the signature to analyse the most sensitive component.Design/methodology/approachThis study presents a ring-shaped network system where this type of topology forms a single continuous pathway for signals through every node. In this study, a system consists of ring network topology is generalized in the series–parallel mixed configuration and reliability characteristics are evaluated with the assistance of universal generating function (UGF) technique. The system consists of wires, repeaters, components or computers and power supply. The wires and repeaters are in series, so, if they fail the whole system will fail and the signals will not go further. The components or computers are connected to each other in parallel configuration. So, the whole system will not fail until the last computer is working. There is also a two-unit power supply system which has one unit in a standby mode. On the failure of first power supply, the second one will start functioning and the whole system fails on the failure of both power supply.FindingsBy the assistance of UGF technique, reliability function of the framework is evaluated. Also, Barlow–Proschan index and expected lifetime for the designed system is estimated by considering a numerical example for the general ring-shaped network system.Originality/valueUGF technique is very effective for estimating the reliability of a system with complex structure and having two performance rates, i.e. completely failed and perfectly working, or more than two, i.e. multi-state performance. This technique enables to estimate every components contribution in the working and failure of the whole system. A general model of ring-shaped network system is taken and generalized algorithm is drawn for the system. Then a particular numerical example is solved for illustrating the use of this technique.
Being a retailer: narratives not on display
Authors: Ruth Damian , Gunn Frances , Elms Jonathan 
Published: October 2021

PurposeThe purpose of this paper is to explore the everyday tasks and activities undertaken by retailer entrepreneurs and owner/managers when they strategize. Specifically, it interrogates the nature of the intuitive, idiosyncratic strategic agency of a retail owner/manager.Design/methodology/approachThrough adopting a combination of phenomenological and narrative approaches, focussing on illuminating the everyday operational and strategic practices of one retail entrepreneur and owner/manager, a richly contextualized, ideographic account of the procedures and outcomes of their strategizing is provided.FindingsBy revealing narratives that are seldom obvious – often kept behind the counter, and not on display – the authors are able to unravel the social reality of the retailer's decision-making, and the influences of identity, connections with customers and community, emotions and the spirit, and love and family. This study also illuminates how entrepreneurs retrospectively make sense out of the messiness of everyday life particularly when juggling the melding of personal and business realities.Research limitations/implicationsThis paper explores the experiences and reflections of the decision-making of one retail entrepreneur manager within a particular business setting. However, the use of an ideographic approach allowed for an in depth investigation of the realities of strategic practices undertaken by a retail owner that may be extrapolated beyond this immediate context.Originality/valueThis paper develops original insights into the retailer as an individual, vis-à-vis an organization, as well as nuanced understanding of the actual nature of work undertaken by retail entrepreneurs and owner/managers. To this end, this paper contributes to the “strategy-as-practice” debate in the strategic management literature, and to narrative analysis and advances insights to the perennial question: “what is a retailer?”.
Investigating the impact of home-sharing on the traditional rental market
Authors: Zhang Xiuzhi , Lin Zhijie , Maeng Junghyun 
Published: October 2021

PurposeThe sharing economy has enjoyed rapid growth in recent years, and entered many traditional industries such as accommodation, transportation and lending. Although researchers in information systems and marketing have attempted to examine the impacts of the sharing economy on traditional businesses, they have not yet studied the rental housing market. Thus, this research aims to investigate the impact of the sharing economy (i.e. home-sharing) on traditional businesses (i.e. rental housing market).Design/methodology/approachThe authors assemble rich data from multiple sources about the entry of a leading Chinese home-sharing platform (i.e. Xiaozhu.com) and local housing rental price index. Then, econometric models (i.e. linear panel-level data models) are employed for empirical investigation. Instrumental variables are used to account for potential endogeneity issues. Various robustness checks are adopted to establish the consistency of the findings.FindingsOverall, the estimation results show that the entry of a home-sharing platform will decrease the local housing rental price. Moreover, this impact would be strengthened in a more developed city. Additionally, this impact would be strengthened with higher prices of new houses or second-hand houses.Originality/valueFirst, this research is one of the first to study the impact of the sharing economy (i.e. home-sharing) on traditional markets (i.e. housing rentals). Second, it contributes to the relevant literature by documenting that the impact of a platform's entry is not uniform but contingent on city and housing market characteristics. Third, practically, the findings also offer important implications for platform operators and policy makers.
Packages of management control systems, entrepreneurial orientation and performance in Brazilian startups
Authors: Frare Anderson Betti , Cruz Ana Paula Capuano da , Lavarda Carlos Eduardo Facin , Akroyd Chris 
Published: October 2021

Purpose
This study aims to understand the relationship between the elements of a startup firms’ management control system (MCS) package, its entrepreneurial orientation (EO) and firm performance.

Design/methodology/approach
The authors collected survey data from a sample of 100 Brazilian startups who had exited technology-based parks and incubators. The authors used two data analysis techniques, namely, partial least squares structural equation modeling (PLS-SEM) and fuzzy-set qualitative comparative analysis (fsQCA).

Findings
The findings show that cultural and planning controls were the only two MCS elements that were included in all high-performing startup firms’ MCS packages. The authors also found that EO has a positive influence on firm performance through the MCS package.

Research limitations/implications
The mixed-method approach allowed for a holistic view of the analyzed phenomenon. PLS-SEM analysis was applied to the symmetric relationships between the proposed relationships while fsQCA was used to analyze the asymmetric combinations between EO dimensions and MCS package elements, which promoted high firm performance.

Practical implications
The authors show how different combinations of MCS elements form a package, mediating EO, which can enable high performance.

Originality/value
Using fsQCA and PLS-SEM, the authors were able to better understand the important role that MCS package adoption has on a startups’ performance and provide new evidence regarding the interface between MCS and EO. This extends the understanding of the importance that cultural and planning controls have in an MCS package to support startup performance.
