Small, fat-filled lipid droplets remain spherical as they indent a nucleus, dilute the lamina, and cause rupture

Published: September 2022

AbstractThe nucleus in many cell types is a stiff organelle, and yet fat-filled lipid droplets (FD’s) in the cytoplasm can be seen to indent and displace the nucleus. FD’s are phase-separated liquids with a poorly understood interfacial tension γ that determines how FD’s interact with other organelles. Here, micron-sized FD’s remain spherical as they indent both the nucleus and peri-nuclear actomyosin, dilute Lamin-B1 locally independent of Lamin-A,C, and trigger rupture with locally persistent accumulation in the nucleus of cGAS, a cytosolic DNA sensor. FD-nucleus interactions initiate rapid mis-localization of the essential DNA repair factor KU80, and nuclear rupture associates with DNA damage and perturbed cell cycle. Similar results are evident in FD-laden cells after constricted 3D-migration, which is impeded by FD’s. Spherical shapes of small FD’s are consistent with a high γ that we measure for FD’s mechanically isolated from fresh adipose tissue as ∼40_mN/m – which is far higher than other liquid condensates, but typical of oils in water and sufficiently rigid to disrupt cell structures.
DC fault current-limiting method based on dual-loop active control for modular multilevel converters
Authors: Quan Lijian , Zeng Guohui 
Published: September 2022

Purpose
In the event of a DC short-circuit fault in a flexible DC power grid, the high peak value of the fault current puts forward more stringent requirements on the DC circuit breaker. The existing fault current cutoff mainly focuses on changing the topology structure. To suppress the development of fault current and reduce the investment cost of the DC grid, this paper aims to propose a dual-loop active current-limiting control based on energy difference.

Design/methodology/approach
Firstly, the equivalent circuit at fault is established, and the parameters related to the fault current are analyzed. Then, the relationship between the output voltage change of the bridge arm and the difference between the AC and DC energy is deduced. Finally, the experimental results are discussed on the real-time simulation platform Opal-RT.

Findings
The proposed current-limiting measures can greatly reduce the fault current, reduce the breaking current of the circuit breaker and increase the capacitor voltage during the fault period, which is beneficial to the stability of the AC system. It is verified that the proposed method is also applicable to a certain high-resistance fault.

Originality/value
This paper applies the method of AC fault to DC fault and deduces the relationship between energy difference and voltage variation corresponding to different step lengths based on digital simulation. In addition, two variables are used as control structure parameters to reduce the probability of system misoperation.

Published: September 2022

PurposePlatform work challenges the traditional modes of workers' organising for interest representation. This paper aims to examine the political potential for voice and representation of the organising efforts by ride-hailing drivers in Ghana.Design/methodology/approachThe study design was qualitative and exploratory. Semi-structured interviews and focus group discussions with individual drivers, key persons and leaders of ride-hailing drivers' associations were employed. The total number of participants was 40.FindingsThe analysis reveals a bottom-up approach to organising, starting with drivers' exercise of associational power (AP) to self-organise with a membership logic. Affected by mundane internal challenges and limited by the non-existent institutional power and the near absence of structural power for right claiming, they affiliate with TUC as the traditional structural power holders for political influence.Research limitations/implicationsThe study has limitations that can be addressed in future research. First, the targeted and small sample size only allows for rich context-specific generalisation. Future studies could target more categories of respondents such as vehicle owners and riders and also seek to include the experiences from other African countries to understand country-specific contextual issues. Second, the allowance for researcher reflexivity inherent in the methodology adopted has the potential for researcher biases. Therefore, a deliberate effort was made to ensure that biases remain only a potential. This was done by participant validation of the data and constant peer-reviewing of the data analysis processes by the authors.Practical implicationsThe empirical findings provide trade unions with a stronger basis for and pointers to represent workers in the platform space.Originality/valuePlatform work in Ghana is an emerging phenomenon, and organising amongst platform workers remains unexplored.
The need for attention to mental health of nursing staff during COVID-19 pandemic as their basic human right
Authors: Abdollahzade Sina , Rafiei Sima , Souri Saber 
Published: September 2022

Purpose
This purpose of this study was to investigate the role of nurses’ resilience as an indicator of their mental health on sick leave absenteeism during the COVID-19 pandemic.

Design/methodology/approach
This descriptive-analytical study was conducted in 2020 to identify the predictors of absenteeism among 260 nurses working in two training hospitals delivering specialized services in the treatment of COVID-19 patients. Data was collected through the use of standard questionnaires including demographic information, nurses’ resilience, intention for job turnover and absenteeism from the workplace. To predict sick leave absenteeism, regression analyses were implemented.

Findings
Study results revealed that the most influencing features for predicting the probability of taking sick leave among nurses were marital status, tenacity, age, work experience and optimism. Logistic regression also depicted that nurses who had less faith in God or less self-control were more likely to take sick leave.

Practical implications
The resilience of nurses working in the COVID-19 pandemic was relatively low, which needs careful consideration to apply for organizational support. Main challenge that most of the health systems face include an inadequate supply of nurses which consequently lead to reduced efficiency, poor quality of care and decreased job performance. Thus, hospital managers need to put appropriate managerial interventions into practice, such as building a pleasant and healthy work environment, to improve nurses’ resilience in response to heavy workloads and stressful conditions.

Originality/value
To the best of the authors’ knowledge, this is the first study to examine such a relationship, thus contributing findings will provide a clear contribution to nursing management and decision-making processes. Resilience is an important factor for nurses who constantly face challenging situations in a multifaceted health-care system.

Authors: Sissoko Mamadou , Theriault Veronique , Smale Melinda 
Published: September 2022

PurposeThe authors assess the development potential of cowpea beyond grain in local markets in Mali by: (1) identifying trader types and types of cowpea products sold; (2) examining trader roles; (3) estimating gross margins and their determinants; and (4) discussing policy opportunities to further develop the value chain.Design/methodology/approachThe authors analyze data collected through observation and semi-structured questionnaires from 487 sellers in 26 markets, including market, seller, and product characteristics. The authors also calculate gross margins and conduct a regression analysis to identify influential factors.FindingsThe authors identify several types of cowpea sellers in local markets, including processor-retailers, retailers of fresh leaves and fodder, and grain retailers, collectors and wholesalers. Women dominate the marketing of processed products and fresh leaves. The marketing of boiled cowpeas offers retailers higher margin rates compared to fritters and pancakes. Grain sellers, who are mostly men, have lower margins but sell larger quantities. Processor-retailers bring more value to the cowpea value chain. Specialization of the seller in cowpea, regional location of the market and day of the market fair all influence gross margins.Research limitations/implicationsFuture work should explore consumer preferences for different types of cowpea products.Originality/valueThis study of the cowpea value chain in Mali has revealed the multidimensional character of the cowpea plant, which goes far beyond its grain and highlight the important roles played by women.
Exploration of the mediating role of physicians’ managerial attitude in the relationship between their self-efficacy and workplace performance
Authors: Morandi Federica , Leonelli Simona , Di Vincenzo Fausto 
Published: September 2022

PurposeSelf-efficacy, or a person’s belief in his/her ability to perform specific tasks, has been correlated with workplace performance and role adjustments. Despite its relevance, and numerous studies of it in the management literature, evidence regarding its function in professionals employed in hybrid roles, such as doctor-managers, is lacking. The aim of this study was to fill this gap by exploring the mediating effect of physicians’ managerial attitude on the relationship between their self-efficacy and workplace performance.Design/methodology/approachPrimary and secondary data from 126 doctor-managers were obtained from the Italian National Health Service. A structural equation modeling approach was used for analysis.FindingsThis study’s results provide for the first time empirical evidence about a surprisingly little-analyzed topic: how physicians’ managerial attitude mediates the relationship between their self-efficacy and workplace performance. The study offers important evidence both for scholars and organizations.Practical implicationsThis study’s results provide valuable input for the human resources management of hybrid roles in professional-based organizations, suggesting a systematic provision of feedback about doctor-managers’ performance, the adoption of a competence approach for their recruitment, and a new design of doctor-managers’ career paths.Originality/valueThe authors provide new evidence about the importance of managerial traits for accountable healthcare organizations, documenting that behavioral traits of physicians enrolled into managerial roles matter for healthcare organizations success.

Authors: Utkina Maryna , Reznik Oleg , Pavlenko Liudmyla 
Published: September 2022

Purpose
This paper aims to illustrate the main changes during martial law for conducting financial intelligence (monitoring), in particular, in the system of combating legalisation (laundering) of illegally gained income.

Design/methodology/approach
The research methodology includes general scientific methods of cognition. The authors used it to research the theoretical, organisational and legal aspects of financial intelligence (monitoring) in normal situations and during martial law. The authors also use the doctrinal legal research method to analyse and describe the legislation connected to the financial intelligence (monitoring) during martial laws.

Findings
This paper is an original work written by authors that discusses financial intelligence (monitoring) during martial law. The following changes in the conduction of financial intelligence (monitoring) were highlighted: suspension of scheduled and unscheduled on-site inspections; postponement of the entry into force of the provisions of some regulations on the submission of reports in electronic form; and the norms amending to remove administrative barriers in matters of financial intelligence (monitoring) in martial law. The authors also noted that certain rules for the functioning of the financial intelligence (monitoring) system were being clarified. Thus, the financial intelligence (monitoring) regime is being weakened to some extent.

Originality/value
In connection with the introduction of martial law in the territory of Ukraine on 24 February 2022, the most important changes that have taken place in the banking and financial sectors of the economy should be mentioned. In particular, this applies to the issues of the regulation on the statutory and regulatory levels. Certain vital points regarding the mechanism and procedures for conducting financial intelligence (monitoring) also needed to be changed, on a need-to-know basis to adapt to the needs of Ukrainian society during the military aggression of the Russian Federation. This paper is devoted to the study of financial intelligence (monitoring) during martial law. The authors identified the main changes in the procedure for conducting financial intelligence (monitoring) by both the National Bank of Ukraine (one of the main entities) and the legislator (by amending the current regulatory framework).

Published: September 2022

PurposeThis study examines what is the significance of the features of inter-organizational relationships in consecutive phases of the relationship life cycle.Design/methodology/approachQu antitative, large-scale surveying was run on 786 software developers operating in Poland. The research hypothesis regarding the systematic increase of relational features (i.e. commitment, communication, (lack of) conflict, cooperation, intensity, investments, longevity, multidimensionality of bonds, trust, and velocity) across the particular relationship life cycle phase le (i.e. initial, development, maintenance, dormant/end, and reactivation) was verified using ANOVA and post-hoc tests.FindingsThe results show that the majority of considered features of inter-organizational relationships non-significantly but progressively strengthen from the initial phase, through the development phase, to the maintenance phase, then significantly weaken in the dormant/end phase and strengthen again in the reactivation phase. Interestingly, velocity–as the only examined feature–significantly increases in dormant/end and then decreases if the relationship is reactivated.Originality/valuePrior studies were focusing on single feature, this one offers a holistic view considering ten relational facets. Moreover, this is one of the few research studies exploring the changes of relational features adopting the life cycle perspective.

Authors: Chmielewska Agnieszka , Wysocki Bartlomiej Adam , Gadalińska Elżbieta , MacDonald Eric , Adamczyk-Cieślak Bogusława , Dean David , Świeszkowski Wojciech 
Published: September 2022

Purpose
The purpose of this paper is to investigate the effect of remelting each layer on the homogeneity of nickel-titanium (NiTi) parts fabricated from elemental nickel and titanium powders using laser powder bed fusion (LPBF). In addition, the influence of manufacturing parameters and different melting strategies, including multiple cycles of remelting, on printability and macro defects, such as pore and crack formation, have been investigated.

Design/methodology/approach
An LPBF process was used to manufacture NiTi alloy from elementally blended powders and was evaluated with the use of a remelting scanning strategy to improve the homogeneity of fabricated specimens. Furthermore, both single melt and up to two remeltings were used.

Findings
The results indicate that remelting can be beneficial for density improvement as well as chemical and phase composition homogenization. Backscattered electron mode in scanning electron microscope showed a reduction in the presence of unmixed Ni and Ti elemental powders in response to increasing the number of remelts. The microhardness values of NiTi parts for the different numbers of melts studied were similar and ranged from 487 to 495 HV. Nevertheless, it was observed that measurement error decreases as the number of remelts increases, suggesting an increase in chemical and phase composition homogeneity. However, X-ray diffraction analysis revealed the presence of multiple phases regardless of the number of melt runs.

Originality/value
For the first time, to the best of the authors’ knowledge, elementally blended NiTi powders were fabricated via LPBF using remelting scanning strategies.

Published: September 2022

AbstractFacial pigmented spots are one of the phenotypes of skin aging, but no quantitative analysis of spot features such as color intensity, size, anatomical position, and number on the cheek has yet been performed. In the current study, we conducted an epidemiological survey of 454 Japanese women in their 20s to 70s and analyzed age‐related changes and site differences of facial pigmented spots. Using image analysis of high‐resolution digital facial photographs, 4912 individual pigmented spots were quantified according to color, size, anatomical position, and total number on the cheek. As a result of color analysis, the color intensity of individual pigmented spots increased with aging, significantly so between ages 30s and 50s. The age‐related increase in melanin index of facial spots was confirmed in all sites but did not significantly differ between facial subregions. Regarding the size of pigmented spots, the frequency of large spots increased with age, and large spots were detected in all facial sites. The total number of pigmented spots on the entire cheek increased with aging, significantly so between the 20s and 40s. The number of pigmented spots tended to increase from the region near the canthi to the lower cheeks. The number of spots was markedly increased in the buccal regions compared with the infraorbital and zygomatic regions. The data and methodology presented in the current study can link the state of facial pigmentation with the various factors involved in the histological development of pigmented spots, opening new possibilities in the fields of skin pharmacology and dermatology.
Interaction networks reveal highly antagonistic endophytic bacteria in native maize seeds from traditional milpa agroecosystems
Authors: Gastélum Gabriela , Aguirre‐von‐Wobeser Eneas , de la Torre Mayra , Rocha Jorge 
Published: September 2022

AbstractMilpas are traditional Mesoamerican agroecosystems maintained with ancestral practices. Maize landraces are grown in polyculture, creating highly productive and diverse ecosystems. Recent studies suggest that milpas maintain beneficial plant–microbe interactions that are probably absent in modern agroecosystems; however, direct comparisons of the microbiome of plants between traditional and modern agroecosystems are still needed. Here, we studied seed‐endophytic bacterial communities from native maize landraces from milpas and hybrid varieties. First, we quantified the abundance of culturable endophytic microbes; next, we assessed pairwise antagonistic interaction networks between bacterial isolates; finally, we compared bacterial community structure by 16S rRNA amplicon sequencing. We found that seeds from native maize landraces harbour a higher endophytic microbial load, including more bacterial strains with antagonistic activity against soil‐borne bacteria, and overall harbour more diverse bacterial communities than the hybrid varieties. Noteworthy, most of the seed‐endophytic strains with antagonistic activity corresponded to Burkholderia spp. that were only found in native maize seeds, through both culture‐dependent and independent strategies. Altogether, our results support that crop modernization alters the functions and structure of plant‐associated microbes; we propose native maize from milpas could serve as a model for understanding plant–microbe interactions and the effect of modernization.
Teaching good sex: The limits of consent and the role of the virtues
Authors: Archard David 
Published: September 2022

Abstract
I offer an account of sexual ethics, and thus of an education in sexual morality, that tries to make some sense of how a view of consent as central to those ethics might be combined with an education in certain virtues. I do so by exploring what some see as the shortcomings of a standard of consent, namely, how it can deal with instances of prima facie bad sex. I consider and reject various attempts to show that consensuality is sufficient for morally good sex. I then show how a needed supplement to the standard of consent can appeal to a broader view of why consent matters. This in turn connects to those personal and interpersonal virtues that the 2019 Department of Education guidance on relationships and sex education suggests should be taught. Finally, I provide an account of why more than consensuality is needed in the case of sex. In short, I insist on the critical importance of consent but supplement the standard of consent by an appeal to why consent matters and does so especially in the case of sex.
