Published: August 2022

AbstractThe human louse,Pediculus humanus, is an obligate blood-sucking ectoparasite that has coevolved with humans for millennia. Given the intimate relationship between this parasite and the human host, the study of human lice has the potential to shed light on aspects of human evolution that are difficult to interpret using other biological evidence. In this study, we analyzed the genetic variation in 274 human lice from 25 geographic sites around the world by using nuclear microsatellite loci and female-inherited mitochondrial DNA sequences. Nuclear genetic diversity analysis revealed the presence of two distinct genetic clusters I and II, which are subdivided into subclusters: Ia-Ib and IIa-IIb, respectively. Among these samples, we observed the presence of the two most common louse mitochondrial haplogroups: A and B that were found in both nuclear Clusters I and II. Evidence of nuclear admixture was uncommon (12%) and was predominate in the New World potentially mirroring the history of colonization in the Americas. These findings were supported by novel DIYABC simulations that were built using both host and parasite data to define parameters and models suggesting that admixture between cI and cII was very recent. This pattern could also be the result of a reproductive barrier between these two nuclear genetic clusters. In addition to providing new evolutionary knowledge about this human parasite, our study could guide the development of new analyses in other host-parasite systems.

AbstractCold-chain environment could extend the survival duration of SARS-CoV-2 and increases the risk of transmission. However, the effect of clod-chain environmental factors and packaging materials on SARS-CoV-2 stability and the efficacy of intervention measures to inactivate SARS-CoV-2 under cold-chain environment remains uncertain. This study aimed to unravel cold-chain environmental factors that preserved the stability of SARS-CoV-2 and disinfection measures against SARS-CoV-2 under the cold-chain environment. The spike gene of SARS-CoV-2 isolated from Wuhan hu-1 was used to construct the SARS-CoV-2 pseudovirus and used as model of the SARS-CoV-2 virus. The decay rate of SARS-CoV-2 pseudovirus in the cold-chain environment, various types of packaging material surfaces i.e., PE plastic, stainless steel, Teflon and cardboard, and in frozen seawater was investigated. The influence of LED visible light(wavelength 450 nm-780 nm) and airflow movement on the stability of SARS-CoV-2 pseudovirus at -18° C were subsequently assessed. The results show that SARS-CoV-2 pseudovirus decayed more rapidly on porous cardboard surface compared with the non-porous surfaces including PE plastic, stainless steel and Teflon. Compared with 25° C, the decay rate of SARS-CoV-2 pseudovirus was significantly lower at low temperature. Seawater preserved viral stability both at -18° C and repeated freeze-thawing cycles compared with deionized water. LED visible light illumination and airflow movement environment at -18° C reduced the SARS-CoV-2 pseudovirus stability. In conclusion, our results indicate cold-chain temperature and seawater as risk factors for SARS-CoV-2 transmission and LED visible light illumination and airflow movement as possible disinfection measures of SARS-CoV-2 under the cold-chain environment.ImportanceIt is widely recognized that low temperature is a condition for maintaining virus vitality, and cold-chain transportation spreads the events of the SARS-CoV-2 were reported. This study provides that the decay rate of the SARS-CoV-2 pseudovirus at low temperatures varies on different packaging materials, and salt ions present in frozen foods such as seafood may protect virus survival. These results provide evidence for the possibility of SARS-CoV-2 transmission through cold-chain transport and also suggest the importance for disinfection of items. However, the commonly used disinfection methods of ultraviolet radiation and chemical reagents are generally not suitable for the disinfection of frozen food. Our study shows LED visible light illumination and airflow movement as possible disinfection measures of SARS-CoV-2 under the cold-chain environment. This has implications for reducing the long-distance transmission of the virus through cold-chain transportation.

COVID 19 pandemic affected 17.2% of the respondents’ physical health. The lockdown improved bonding among family members (74.6%), also the lockdown favourable affected 56.0% of the respondents’ emotional health. The spirituality of the respondents was negatively affected (79.9%) by the lockdown, family expenses were increased (82.6%), there was an increased in the prices of goods (92.9%), and in general COVID 19 pandemic unfavorably affected (77.2%) the respondents’ socio-economic health.ConclusionThis study reveals that COVID-19 and the lockdown produced an adverse effect on the physical, emotional, spiritual, and socio-economic wellbeing of the families in southwest Nigeria.Implications for nursing and health policynurses working in COVID-19 unit need to give total care to the affected patient; therefore, they have obligation to include physical, emotional, spiritual and mental intervention in their care. The government needs to plan and strategize properly in the method for distribution of the palliative’s, and if possible identify the vulnerable and less privileged in each state for easy distribution.
Yolk granule fusion and microtubule aster formation regulate cortical granule translocation and exocytosis in zebrafish oocytes
Authors: Shamipour Shayan , Hofmann Laura , Steccari Irene , Kardos Roland , Heisenberg Carl-Philipp 
Published: August 2022

AbstractDynamic reorganization of the cytoplasm is key to many core cellular processes, such as cell division, cell migration and cell polarization. Cytoskeletal rearrangements are thought to constitute the main drivers of cytoplasmic flows and reorganization. In contrast, remarkably little is known about how dynamic changes in size and shape of cell organelles affect large-scale cytoplasmic organization. Here, we show that within the maturing zebrafish oocyte, the surface localization of exocytosis-competent cortical granules upon germinal vesicle breakdown is achieved by the combined activities of yolk granule fusion and microtubule aster formation and translocation. We find that cortical granules are moved towards the oocyte surface through radially-outward cytoplasmic flows induced by yolk granules fusing within the oocyte center in response to GV breakdown. We further show that vesicles decorated with the small Rab GTPase Rab11, a master regulator of vesicular trafficking and exocytosis, accumulate together with cortical granules at the oocyte surface. This accumulation is achieved by Rab11-positive vesicles being transported by acentrosomal microtubule asters, the formation of which is induced by the release of CyclinB/Cdk1 upon GV breakdown, and which display a net movement towards the oocyte surface by preferentially binding to the oocyte actin cortex. We finally demonstrate that the decoration of cortical granules by Rab11 at the oocyte surface is needed for cortical granule release and subsequent chorion elevation, a process central in oocyte activation. Collectively, these findings unravel a yet unrecognized role of organelle fusion, functioning together with cytoskeletal rearrangements, in determining cytoplasmic organization during oocyte maturation.
Investigation on static and dynamic characteristics of high-speed and heavy-load tilting pad journal bearings
Authors: Yan Kanghao , Huang Dan 
Published: August 2022

Purpose
Multitilting-pad journal bearings (MTPJBs) used in large-scale hydraulic turbines often suffer from complex operating conditions, which greatly influence the overall performance of the rotating machine. The purpose of this study is to establish a thermal-elastic-hydrodynamic lubrication model for MTPJBs that can predict the static and dynamic characteristics of high-speed and heavy-load MTPJBs under different operating conditions.

Design/methodology/approach
A thermo-elasto-hydrodynamic lubrication model considering the turbulence effect is proposed for high-speed and heavy-load TPJBs, which is solved using the coupled finite difference method and finite element method. The model considered the turbulence effect, thermal energy diffusion, viscosity–temperature–pressure relationship and elastic deformation of the pads. The influences of the operating conditions on static and dynamic characteristics of tilting pad journal bearings were analyzed in depth.

Findings
The operating conditions have a strong effect on the static properties of the bearings. The dynamic characteristics of the TPJB were the most influenced by the shaft speed. The effects of the load direction on the dynamic properties of the TPJB were much stronger than those of the static characteristics.

Originality/value
This study used analytical methods and models to provide theoretical guidance for evaluating lubricating characteristics, assembling conditions and overall health.
The impact of context clues on online review helpfulness
Authors: Namvar Morteza , Chua Alton Y.K. 
Published: August 2022

PurposeThis paper seeks to propose and empirically validate a conceptual model on the antecedents of review helpfulness comprising three constructs, namely, valence dissimilarity, lexical dissimilarity and review order.Design/methodology/approachA panel dataset of customer reviews was collected from Amazon. Using deep learning and text processing techniques, 650,995 reviews on 13,612 products from 570,870 reviewers were analyzed. Using negative binomial regression, four hypotheses were tested.FindingsThe results indicate that new reviews with high valence dissimilarity and lexical dissimilarity compared to existing reviews are less helpful. However, over the sequence of reviews, the negative effect of review dissimilarity on review helpfulness can be moderated. This moderation differs for valence and lexical dissimilarity.Research limitations/implicationsThis study explains review dissimilarity in the context of online review helpfulness. It draws on the elaboration likelihood model and explains how the impacts of peripheral and central cues are moderated over the sequence of reviews.Practical implicationsThe findings of this study provide benefits to online retailers planning to implement online reviews to improve user experience.Originality/valueThis paper highlights the importance of review dissimilarity in identifying user perception of online review helpfulness and understanding the dynamics of this perception over the sequence of reviews, which can lead to improved marketing strategies.

Authors: Syed Sumaiya , Memon Salman Bashir , Shah Abdul Qadir 
Published: August 2022

PurposeThe qualitative study was conducted to examine work-family (W-F) balance practices in the collectivist culture of Pakistan. Keeping in view the context of Pakistan, three W-F practices, flexibility, childcare arrangement and social support, were studied by applying the theory of W-F balance.Design/methodology/approachIn total, 16 In-depth interviews from the bank operating in three different cities in Sindh, Pakistan.FindingsData analysis showed that providing economic benefits and short working hours can achieve W-F balance. Nevertheless, the provision of flexibility in terms of short working hours is more important than economic benefits in balancing both domains of life. Secondly, the provision of childcare arrangements helps to balance work and home life. This practice favors females more compared to males. Thirdly, supervisor and co-worker support is most important in creating W-F balance than family support.Research limitations/implicationsIt is crucial to understand the W-F balance practices in developing countries; the bank should encourage policies related to flexibility, childcare arrangement and social support in Pakistan. In addition, banks should take the initiative to develop a way that facilitates the employees' social support, which should consequently help to achieve the W-F balance.Practical implicationsIt is crucial to understand the W-F balance practices in developing countries; the bank should encourage policies related to flexibility, childcare arrangement and social support in Pakistan. Banks should take an initiative to develop a way that facilitates the employees' social support which should consequently help to achieve the W-F balance.Social implicationsThis research has a tremendous impact on society due to current changes in South Asian countries including Pakistan constitute a socio-cultural transition that directly affects working and family life.Originality/valueGiven the importance of W-F balance in recent times, the authors identified and extended the W-F balance practices in the collectivist culture of Pakistan. This study is novel and contributes to the W-F balance literature by considering most primary W-F balance practices that employees require.
Do personal traits of the leader predict differences in leader and subordinate evaluations of leader effectiveness: a study in the banking industry in Ethiopia
Authors: Ali Habtamu Endris , Schalk René , van Engen Marloes 
Published: August 2022

PurposeThis study aims to examine whether the internal locus of control, self-esteem and leadership self-efficacy can predict differences in self–other rating agreement on leader effectiveness. First, the authors predicted that the greater the internal locus of a leader the more their self-rating will be in agreement with others' rating of them (1a). Second, the authors proposed that the greater the self-esteem of a leader the more their self-rating will be in discrepancy with others' rating (1b). Third, the authors hypothesized that the greater the self-efficacy of a leader the more their self-rating will be in agreement with others' rating (1c).Design/methodology/approachTo test the hypotheses, multisource data were collected from 128 banking leaders (who responded about different aspects of leadership self-efficacy, internal locus of control, self-esteem and leadership effectiveness) and 344 subordinates (who rated their leaders' effectiveness in performing leadership tasks).Multivariate regression was performed by jointly regressing both leaders' self-ratings and subordinates' ratings as a dependent variable on internal locus of control, self-esteem and leadership self-efficacy as predictor variables.FindingsSelf-esteem of a leader the more their self-rating will be in discrepancy with others' ratings.Originality/valueThe study tried to investigate the leader-subordinate dis(agreement) on leaders’ effectiveness taking banking leaders in the Ethiopian Context. The finding of the results is crucial and important for leadership development programs.
Cooperative values and the development of the credit union movement in Australia
Authors: Unda Luisa 
Published: August 2022

Purpose
Credit unions offer an alternative to traditional banking given their distinctive ownership structure and their goal of maximising members’ benefits. Motivated by the increased expectations regarding more ethical behaviour in the financial industry, this paper aims to provide a better understanding of the relevant features and values that facilitated the emergence of the credit union movement in Australia.

Design/methodology/approach
Using social movement theory, this study analyses 23 interviews conducted in the early 1990s with the supporters of the credit union movement in Australia, in which the characteristics and values of the credit union movement are identified.

Findings
Findings demonstrate that the credit union ethos is rooted in family and religious influences, and that these organisations were keen on promoting their distinctiveness on “fairness” and “caring for their members”. Credit unions, however, have rarely tackled the movement’s most neglected value “cooperation between cooperatives”.

Originality/value
This research contributes to the discussion of ethics in business history as it elaborates on how values and ethos crafted the identity and ensured the survival of the credit union movement in Australia.
Production and characterization of gum exudate from apricot tree: modeling the rheology of the obtained extract
Authors: Karataş Mukaddes , Aydoğmuş Ercan , Arslanoğlu Hasan 
Published: August 2022

Purpose
This paper aims to investigate the effect of shear rate, concentration (4–20 kg/m3) and temperature (20°C–60 °C) on the apparent viscosity of apricot gum solutions.

Design/methodology/approach
Apparent viscosity has been measured using a rotational viscometer.

Findings
It has been observed that the shear stress and apparent viscosity values increase at high concentrations in the prepared apricot gum solutions. However, it is understood that the higher the temperature in the operation conditions, the lower the apparent viscosity results. Power-law is found the best-fitting model to illustrate the changes in temperature and concentration. According to the consistency coefficient and flow behavior indices, the apricot gum displayed shear-thinning behavior (pseudoplastic). The apricot gum is a polysaccharide with amino and uronic acids, according to Fouirer Transform Infrared Spektrofotometre spectra.

Practical implications
The results suggest that power-law model can be used to estimate the viscosity of apricot gum solutions at different temperatures and concentrations for applications for which flow behavior should be taken into account.

Originality/value
Exudate gums have good rheological properties and, therefore, are widely used in the food industry. Apricot gum is a biodegradable and abundant polysaccharide that enhances viscosity, stabilizes suspension or emulsion and improves the flow properties of foods. Different rheological models are used to investigate rheological properties. However, those models are time-independent to fit the experimental data.

‘No objection to go abroad’: Servants' Travel Advertisements in The Morning Post, London, 1815
Authors: Dunn Sophie 
Published: August 2022

AbstractThis article focuses on newspaper advertisements posted by, or on behalf of, servants who were offering their services to travellers to the European continent at the end of the long eighteenth century. Advertising their travel‐related skills, such as languages or knowledge of the roads, travelling servants positioned themselves as ideal travel companions who anticipated their employers' needs and used their skills as a self‐marketing strategy to stand out in a competitive job market. These advertisements give us an idea how servants imagined worthwhile employment, what they desired or objected to, and where they were willing to compromise.

AbstractAccurate identification of plants remains a significant challenge for taxonomists and is the basis for plant diversity conservation. Although DNA barcoding methods are commonly used for plant identification, these are limited by the low amplification success and low discriminative power of selected genomic regions. In this study, we developed a k‐mer–based approach, the DNA signature sequence (DSS), to accurately identify plant taxon‐specific markers, especially at the species level. DSS is a constant‐length nucleotide sequence capable of identifying a taxon and distinguishing it from other taxa. In this study, we performed the first large‐scale study of DSS markers in plants. DSS candidates of 3899 angiosperm plant species were calculated based on a chloroplast data set with 4356 assemblies. Using Sanger sequencing of PCR amplicons and high‐throughput sequencing, DSSs were validated in four and 165 species, respectively. Based on this, the universality of the DSSs was over 79.38%. Several indicators influencing DSS marker identification and detection have also been evaluated, and common criteria for DSS application in plant identification have been proposed.
