Authors: Jauhar Sunil Kumar , Chakma B. Ripon , Kamble Sachin S. , Belhadi Amine 
Published: June 2023

PurposeAs e-commerce has expanded rapidly, online shopping platforms have become widespread in India and throughout the world. Product return, which has a negative effect on the E-Commerce Industry's economic and ecological sustainability, is one of the E-Commerce Industry's greatest challenges in light of the substantial increase in online transactions. The authors have analyzed the purchasing patterns of the customers to better comprehend their product purchase and return patterns.Design/methodology/approachThe authors utilized digital transformation techniques-based recency, frequency and monetary models to better understand and segment potential customers in order to address personalized strategies to increase sales, and the authors performed seller clustering using k-means and hierarchical clustering to determine why some sellers have the most sales and what products they offer that entice customers to purchase.FindingsThe authors discovered, through the application of digital transformation models to customer segmentation, that over 61.15% of consumers are likely to purchase, loyal customers and utilize firm service, whereas approximately 35% of customers have either stopped purchasing or have relatively low spending. To retain these consumer segments, special consideration and an enticing offer are required. As the authors dug deeper into the seller clustering, we discovered that the maximum number of clusters is six, while certain clusters indicate that prompt delivery of the goods plays a crucial role in customer feedback and high sales volume.Originality/valueThis is one of the rare study that develops a seller segmentation strategy by utilizing digital transformation-based methods in order to achieve seller group division.

Effect of social media on employee's work performance
Authors: Doshi Parinda , Nigam Priti 
Published: June 2023

PurposeThe paper validates a framework using the media synchronicity theory (MST) to study the effect of Social Media Use at Work (SMUW) on the performance “Work Performance” (WP) of the employee. For this, the study initially observed the effect of SMUW on shared vision (SV), network ties (NT), and trust (TRUST) on the knowledge transfer (KT) and the effect of all (SV, NT, TRUST and KT) on the WP of the employees.Design/methodology/approachA survey method was used to collect responses from 157 employees working at middle and lower-level managerial positions in the chemical companies of India. The data analysis uses variance-based, partial least square SEM, which has established a relationship between the constructs.FindingsThe results found a significant effect of SMUW on the WP of the employees. It was observed that the SV and TRUST can be significantly improved with the help of SMUW, contributing to the KT and simultaneously affecting the WP of the employees.Practical implicationsThe study has examined the positive and significant effect of SMUW on the employees' SV, NT and TRUST. Improving SV, NT and trust (dimension of social capital) through social media allows employees to transfer more knowledge. An increase in KT among the employees further positively affected the individual and group performance within the organization. SV positively affected the employee's WP, but NT and trust negatively affected the WP. The research thus provides useful insight to the managers for effective use of social media in the workplace.Originality/valueThe study used MST to understand the effect of the use of social media in the workplace. The study is kind of first in the Indian context which has examined the effect of employees at managerial level in chemical companies, and thus contributes to the existing literature on social networks/social media from the organizational context.
Personal resources at play: the mediating role of psychological capital in the relationship between new ways of working and life satisfaction
Authors: Vasudevan Priyadharshini , Suganthi L. 
Published: June 2023

PurposeThe new ways of working (NWW), a contemporary work environment with temporal and spatial flexibilities, has become an enforced reality after the COVID-19 pandemic disrupted workplaces. However, the understanding of how it impacts employee well-being perceptions is limited. Hence, the current study aims to examine how the NWW facets, namely, time- and location-independent work, management of output, access to organizational knowledge and flexibility in working relations relate to employees' life satisfaction, mediated by psychological capital.Design/methodology/approachA cross-sectional survey was designed to collect data from 459 Indian knowledge workers. Model fit and the hypothesized relationships were tested using IBM SPSS 25, AMOS and PROCESS Macro.FindingsAll four NWW facets positively relate to psychological capital, which in turn associates with life satisfaction. Except for the facet “management of output”, the other three facets associate positively with life satisfaction before accounting for the mediator. Indirect effects of all four facets on life satisfaction via psychological capital were established. Overall, the findings establish the important mediating role of psychological capital in relating the NWW facets with life satisfaction.Originality/valueBy examining the previously unexplored relationships between NWW, psychological capital and life satisfaction, this study provides novel insights into the role of personal resources in maximizing the beneficial effects of the NWW practices and is highly relevant in the current context where organizations are trying to identify coping mechanisms that help employees adapt to workplace transformations.

PurposeThe present research is trying to construct the network of relationships between different department of an organization during the design and development of car engine. Analyzing the structure of the network, finding the patterns of collaborations, and determining the important departments are the main purposes of the present research.Design/methodology/approachImproving relationships during a project life is an effective way to enhance employee performance in project-oriented organizations. This paper examines the collaborative relationships between internal project stakeholders through social network analysis (SNA) in a project for the design and development of car engine. In the first step of the research, the network of internal stakeholders was studied based on collaboration in the common activities performed by the resources. Then, the network of correspondences between internal stakeholders was studied. Finally, the two networks were integrated into a single network.FindingsIn the integrated network, the “fuel and combustion department” had the largest degree centrality (i.e. highest collaboration with others). The “integration department” was found to have the highest closeness centrality (i.e. more rapid access to other nodes). Furthermore, the “procurement department” had the highest betweenness centrality (i.e. the most strategic department). Our results revealed the potential capabilities of SNA method for the project management in the vehicle industry.Originality/valueThe obtained results of the present research show us the value of applying SNA methods and concepts to analyze the inter-organizational network of the Project Stakeholders relationship.
Inside the “black box” of 1033 Program military equipment use by local law enforcement
Authors: Koslicki Wendy M. 
Published: June 2023

PurposeRecent USA police responses to civil rights demonstrations have drawn attention toward the 1033 Program – a military surplus transfer program from the Department of Defense (DOD) to police agencies in the USA – as well as calls for dissolution or reform of the program. However, policy decisions have been sporadic and empirical literature examining the program have relied on public data, which contain information about equipment transfers, but does not show the frequency of agencies' use of this equipment – or contexts of use – once received.Design/methodology/approachThis study presents the findings of a survey of a national sample of law enforcement agencies that used the program to obtain armored vehicles, rifles, and body armor and how these agencies used this equipment in 2019 and 2020. Correlations and binary logistic regression models are tested for 2019 to examine the racial threat hypothesis and additional predictors of equipment use.FindingsA statistically significant correlation is found between perceived percentage of Black and other race residents and the frequency of armored vehicle deployment in 2019 and between the perceived percentage of other race residents and the percentage of special weapons and tactics (SWAT) officers wearing body armor. Perceived increases in drug crimes also significantly increase the likelihood of SWAT officers carrying military rifles, with increased odds of 402.3%.Originality/valueThis study is the first to examine contextual data surrounding law enforcement use of 1033 Program acquisitions with a national sample, assisting in providing greater accuracy in determining predictors and outcomes of the program's use.
A review and analysis of errors in post‐stack time‐shift interpretation
Authors: MacBeth Colin , Izadian Saeed 
Published: June 2023

AbstractThis study complements two earlier papers on the interpretation and estimation of post‐stack time‐shifts that detail the most popular measurement methods to date. In this current work, the focus is on describing the magnitude and identifying the origin of the uncertainty present in these time‐shift values. We also consider how the underlying assumptions behind conventional time‐shift estimation methods can contribute to the inadequate resolution of the subsurface time‐lapse changes. The various errors fall into three broad categories: (1) those related to intrinsic data limits that cannot be avoided; (2) those associated with seismic measurement methods that can be corrected with some effort; and finally (3) those that arise due to approximations to the wave physics made during the design or implementation of the methods. In the first category are limitations due to sampling rate and signal‐to‐noise ratio, and wavelet interferences resulting from the narrow band nature of the seismic data and the heterogeneous nature of the geology itself. The effects produce errors of typically a fraction of a millisecond, but exceptionally in 4D data with poor repeatability up to 1 ms. In the second category are acquisition and processing errors. These are usually of the order of a few milliseconds but can reach up to 10s of milliseconds and are, therefore, essential to correct. It is possible to correct the effects of tides and seawater variations in marine acquisition if these changes are monitored and measured. Navigation and timing are identified as issues to consider carefully. For land data, daily and seasonal near‐surface variations are still problematic, and source and sensors must be buried to deliver interpretable time‐shifts. The impact of choices made during processing can be significant but is specific to the workflow and dataset and thus cannot be generically assessed. However, the effects from residual multiples can be identified and treated. Of moderate importance is the third category of errors, which consists of four items. Of these, the effect of lateral image shifts and amplitude effects are judged to play a minor role. Deviation from the assumption of vertical ray‐paths during post‐stack analysis appears to be of concern only for reservoirs with noticeably dipping structures and strong contrasts. The effect of pre‐stack variations on the post‐stack measurements remains a topic to be more thoroughly examined, and the conclusion is unclear. Finally, it is apparent that uncertainties in all categories are strongly dependent on the field setting and geographical location.
Unbalancing Zur (FurB)‐mediated homeostasis in Anabaena sp. PCC7120: Consequences on metal trafficking, heterocyst development and biofilm formation
Authors: Olivan‐Muro Irene , Sarasa‐Buisan Cristina , Guio Jorge , Arenas Jesús , Sevilla Emma , Fillat Maria F. 
Published: June 2023

AbstractZinc is required for the activity of many enzymes and plays an essential role in gene regulation and redox homeostasis. In Anabaena (Nostoc) sp. PCC7120, the genes involved in zinc uptake and transport are controlled by the metalloregulator Zur (FurB). Comparative transcriptomics of a zur mutant (Δzur) with the parent strain unveiled unexpected links between zinc homeostasis and other metabolic pathways. A notable increase in the transcription of numerous desiccation tolerance‐related genes, including genes involved in the synthesis of trehalose and the transference of saccharide moieties, among many others, was detected. Biofilm formation analysis under static conditions revealed a reduced capacity of Δzur filaments to form biofilms compared to the parent strain, and such capacity was enhanced when Zur was overexpressed. Furthermore, microscopy analysis revealed that zur expression is required for the correct formation of the envelope polysaccharide layer in the heterocyst, as Δzur cells showed reduced staining with alcian blue compared to Anabaena sp. PCC7120. We suggest that Zur is an important regulator of the enzymes involved in the synthesis and transport of the envelope polysaccharide layer, influencing heterocyst development and biofilm formation, both relevant processes for cell division and interaction with substrates in its ecological niche.
Astragalosides inhibit proliferation of fibroblast‐like synoviocytes in experimental arthritis by modulating LncRNA S56464.1/miR‐152‐3p/Wnt1 signaling axis
Authors: Cui Xiaoya , Wang Jing , Fan Chang , Jiang Hui , Li Weiping 
Published: June 2023

AbstractAimAstragalus membranaceus (Fisch.) Bunge., the dried root of the plant A. membranaceus, is widely used in the treatment of rheumatoid arthritis (RA) in many Chinese herbal remedies. Astragalosides (AST) is the primary medicinal ingredient of A. membranaceus and has a therapeutic effect on RA, but the specific mechanism of this effect has yet to be elucidated.MethodsIn this study, MTT and flow cytometry were used to determine the effects of AST on fibroblast‐like synoviocyte (FLS) proliferation and cell cycle progression. Additionally, real‐time quantitative polymerase chain reaction and Western blotting were used to determine the effects of AST on the LncRNA S56464.1/miR‐152‐3p/Wnt1 signaling axis and on critical genes that are essential to the Wnt pathway.ResultsThe data showed that after the administration of AST, FLS proliferation and LncRNA S56464.1, β‐catenin, C‐myc, Cyclin D1, and p‐GSK‐3β(Ser9)/GSK‐3β expression were significantly reduced, and miR‐152 and SFRP4 expression was notably increased.ConclusionThese results suggest that AST can inhibit FLS proliferation by modulating the LncRNA S56464.1/miR‐152‐3p/Wnt1 signaling axis and that AST may be a potential therapeutic drug for RA.
Descendants over 300 years: Marital fertility in five lineages in Qing China
Authors: Hu Sijie 
Published: June 2023

AbstractThis paper studies the marital fertility—broadly defined as the ratio of live births to married women—of five Chinese lineages since the 17th century, mainly in the Qing Dynasty (1644–1911). The results demonstrate a unique pattern of Chinese marital fertility by exploiting new genealogical data and studying more than 50,000 individuals from five lineages. Contrary to the conventional wisdom, the marital fertility rates in the period were moderate. On the other hand, in line with the classic ideas, this paper finds no clear indication of two fertility controls within marriages, parity‐dependent early stopping and longer spacing.
Unusual presentation of telangiectasia macularis eruptiva perstans at the site of healed herpes zoster; Wolf's isotopic response
Authors: Sarsik Sameh , Soliman Sarah H. , Elhalaby Rofyda Essam 
Published: June 2023

AbstractThere are several reported cases of Wolf's isotopic response, including infections, cancers, inflammatory and immune‐related disorders. It is interesting that the majority of these occurred after herpes zoster (HZ) had healed. In this article, we describe an unusual case of adult mastocytosis/telangiectasia macularis eruptiva perstans (TMEP) at the location of recovered HZ. Given that adult mastocytosis is thought to be caused by dysregulation of the mast cell growth factor receptor, the c‐Kit proto‐oncogene (CD117), and the fact that the varicella zoster virus‐infected cutaneous lesions contain CD117‐positive mast cells (CD117+MCs), we hypothesize that CD117+ MCs may be in charge of the local immunological response and cytokine release those results in TMEP after HZ.

Published: June 2023

BackgroundThe presence of different breast cancer receptor status may impact ovarian stimulation outcomes.AimTo study the association between oestrogen receptor (ER) status in breast cancer patients and fertility preservation outcomes in a major tertiary referral centre.Materials and MethodsWomen who underwent fertility preservation following the diagnosis of breast cancer from 2008 to 2018 were included in the study. Patient age, ovarian stimulation parameters and laboratory outcomes were recorded and compared between the ER positive and negative groups. The primary outcome was total number of oocytes frozen. Secondary outcomes included total number of oocytes collected, mature oocytes, and embryos frozen.ResultsThe women included in the study (n = 214) were analysed in the following groups based on their fertility preservation method: oocyte freezing (n = 131), embryo freezing (n = 70), and both embryo and oocyte freezing (n = 13). There was an increase in the mean (but not mature) number of oocytes frozen (12.4 and 9.2, P‐value = 0.03) favouring the ER positive group, even though the women in this group were older (35.0 and 33.4, P‐value of 0.03). There is no difference in the starting follicle‐stimulating hormone dose, duration of stimulation, mature oocytes collected, and embryos frozen in both groups.ConclusionPatients with ER positive breast cancer may have more positive ovarian stimulation outcomes.
Optic nerve diseases and regeneration: How far are we from the promised land?
Authors: Cen Ling‐Ping , Park Kevin K. , So Kowk‐Fai 
Published: June 2023

AbstractThe retinal ganglion cells (RGCs) are the sole output neurons that connect information from the retina to the brain. Optic neuropathies such as glaucoma, trauma, inflammation, ischemia and hereditary optic neuropathy can cause RGC loss and axon damage, and lead to partial or total loss of vision, which is an irreversible process in mammals. The accurate diagnoses of optic neuropathies are crucial for timely treatments to prevent irrevocable RGCs loss. After severe ON damage in optic neuropathies, promoting RGC axon regeneration is vital for restoring vision. Clearance of neuronal debris, decreased intrinsic growth capacity, and the presence of inhibitory factors have been shown to contribute to the failure of post‐traumatic CNS regeneration. Here, we review the current understanding of manifestations and treatments of various common optic neuropathies. We also summarise the current known mechanisms of RGC survival and axon regeneration in mammals, including specific intrinsic signalling pathways, key transcription factors, reprogramming genes, inflammation‐related regeneration factors, stem cell therapy, and combination therapies. Significant differences in RGC subtypes in survival and regenerative capacity after injury have also been found. Finally, we highlight the developmental states and non‐mammalian species that are capable of regenerating RGC axons after injury, and cellular state reprogramming for neural repair.

AbstractMyxopapillary ependymoma (MPE) is an uncommon variant of ependymoma, almost exclusively seen in conus medullaris or filum terminale. MPE can be diagnostically challenging, especially when arising extra‐axially. Here we report 5 cases of superficial soft tissue/cutaneous MPE, identified across three tertiary institutions. All patients were female and three of them (3/5, 60%) were children (median age 11 years, range 6–58 years). The tumors presented as slow‐growing masses of the sacrococcygeal subcutaneous soft tissues, occasionally identified after minor trauma and clinically favored to be pilonidal sinuses. Imaging showed no neuraxis connection. Macroscopically, tumors were well‐circumscribed, lobulated, and solid and microscopically they exhibited typical histopathology of MPE, at least focally. Two of the tumors (2/5, 40%) showed predominantly solid or trabecular architecture with greater cellular pleomorphism, scattered giant cells, and increased mitotic activity. All tumors (5/5, 100%) showed strong diffuse immunohistochemical expression of GFAP. One tumor clustered at the category “ependymoma, myxopapillary” by methylome analysis. Two patients (2/5, 40%) had local recurrence at 8 and 30 months after the initial surgery. No patients developed metastases during the follow‐up period (median 60 months, range 6–116 months). Since a subset of extra‐axial MPEs behaves more aggressively, timely and accurate diagnosis is of paramount importance.
