The impact of social media usage on expertise coordination and team creative performance in distributed agile software development
Authors: Jiang Jijiao , Yang Xiao , Zhou Cong 
Published: May 2023

PurposeThis article explores how the social media usage affect team creative performance via transactive memory system, knowledge interaction and expertise coordination.Design/methodology/approachThe study is based on the perspective of transaction memory system and expertise coordination theory. A research model was constructed and tested, involving 289 individuals from 67 distributed agile software development teams.FindingsThe results indicate that social media usage is positively correlated with transactive memory system, and social media usage and transactive memory system have positive relations to knowledge interaction and expertise coordination. Moreover, this analysis shows that knowledge interaction has a positive relationship with expertise coordination, and expertise coordination positively affects team creative performance. However, knowledge interaction has no direct relationship on team creative performance, and its indirect impact on team creative performance was fully mediated by expertise coordination. This research shows that social media usage by distributed agile software development teams can support the development of transactive memory system and promote expertise coordination. In addition, knowledge interaction alone is not enough, and expertise coordination must be achieved to increase team creative performance.Originality/valueFirst, this paper explores the mechanism of transactive memory system in distributed Agile Software Development teams from the perspective of social media, which is different from the previous information processing theory framework that confined transactive memory system to the cognitive aspects of knowledge coding, storage and retrieval. Second, this research focuses on the knowledge interaction and expertise coordination formed by team members in the process of communication in the context of social media usage, which confirms the crucial roles of social media usage and transactive memory system in team knowledge management and team creative performance. Then, this research also shows that the development of transactive memory system in the team is indeed an important factor to promote knowledge interaction and professional expertise coordination.

Authors: Eirich Jodi , Wildesen Jane 
Published: May 2023

PurposeThe purpose of this paper is to describe a thriving partnership between Frostburg State University and the Garrett County Public Schools that aims to improve teacher effectiveness and retention through the implementation of a robust induction program. The initiative includes sustained, strategic mentoring; extensive professional development; and validated, competency-based microcredentials aligned to high-leverage practices.Design/methodology/approachThe study included surveys and structured interviews with teaching fellows and their instructional coaches.FindingsHaving ample support and mentoring can make a significant difference for novice teachers. Partnerships between universities and local school districts can provide this critical support.Research limitations/implicationsA limitation that cannot be ignored is the small number of participants in this program, all of whom are teaching in a rural school system. However, researchers working with larger school districts would add valuable knowledge to the field of study.Practical implicationsThis paper includes implications for designing new induction programs or improving existing ones.Social implicationsMentoring, a major component of high-quality induction programs, has the potential of providing important benefits to beginning teachers including increased motivation, self-confidence, growth in professional identity, and reduced stress and anxiety.Originality/valueAs school systems are struggling to retain qualified teachers, high-quality induction programs are necessary.
Emojis and stock returns
Authors: Reschke Felix , Strych Jan-Oliver 
Published: May 2023

PurposeThe authors explore how the sentiment expressed by emojis in comments on stocks is associated with the stocks' subsequent returns.Design/methodology/approachBy applying our own analyzer, the authors find a sentiment effect of emojis on stocks returns separately to the plain text-expressed sentiment in Reddit posts about meme stocks such as Gamestop during the Covid-19 pandemic.FindingsThe authors document that a one-standard deviation change in emoji sentiment magnitude measured as the quantity of positive emoji sentiment posts over the previous hour is associated with an 0.06% (annualized: 109.2%) one-hour abnormal stock return compared to a mean of 0.03% (annualized: 54.6%). If the stock exhibits a higher intra-hour volatility, a proxy for uninformed noise trading, this relation is more pronounced and even stronger compared to stock return's relation to plain text sentiment.Research limitations/implicationsThe authors are not able to show causation that is open to future research. It also remains an open question how emojis impact market price efficiency.Practical implicationsEmojis are positively related to stock returns in addition to plain text-expressed content if they are discussed heavily by retail investors in Internet boards such as Reddit.Social implicationsShared emotions expressed by emojis might have an influence on how disconnected individuals make homogeneous decisions. This argument might explain our found relation of emojis and stock returns.Originality/valueSo, the study findings provide empirical evidence that emojis in Reddit posts convey information on future short-term stocks returns distinct from information expressed in plain text, in the case of volatile stocks, with a higher magnitude.
Contingent resource-based view of food netchain organization and firm performance: a comprehensive quantitative framework
Authors: Adetoyinbo Ayobami , Trienekens Jacques , Otter Verena 
Published: May 2023

Purpose
Much has been written on the effect of fast-moving business environments on organizational and supply chain (SC) management. Yet, empirical findings on the effect of changing external and internal contingencies on today’s globalized agrifood SC networks and performance are still fragmented into different organizational instruments, with some conflicting results remaining unexplained. This study aims to address these deficiencies by providing a comprehensive research framework to investigate how SC external and internal contingencies jointly influence organizational SC network structures and agrifood performance across mutually dependent tiers.

Design/methodology/approach
Using partial least squares structural equation modeling, the so-called “contingency–netchain–performance” framework, based on contingent resource-based theory and the netchain approach, was empirically tested on data obtained from a standardized survey of 405 artisanal producers and 238 processors in the Nigerian shrimp sector.

Findings
The results provide statistical evidence that supports the path dependency of firm performance from the interplay of vertical, horizontal and lateral relationships and, primordially, from both external and internal contingencies. The findings show that the contingency paradigm of fit among small-scale food producers and processors cuts across tiers and uncover a tendency to adopt relational governance and tighter network structures that result in an organic organization as the best-fitting structure.

Originality/value
The paper presents a new research framework that offers comprehensive empirical explanations for the joint influence of SC external and internal contingencies on organizational SC network structures and performance across mutually dependent agrifood tiers. This study’s conceptual, practical and policy implications for SC management provide a nascent and flexible basis on which to identify the best-fitting organizational strategies that maximize firm performance across agrifood SC tiers characterized by changing business environments.
Is Marriage a Turning Point? Evidence from Cash Holdings Behaviour

Published: May 2023

AbstractGiven that marriage transforms people, with wide‐ranging and long‐lasting impacts, we examine the role of CEOs' marital status on firms' cash holdings behaviour. Using a large sample of US‐listed firms, we find that single CEOs stockpile more cash than their married counterparts do. Our finding is robust to controlling for various CEO characteristics, CFO influence, tackling endogeneity concerns and using alternative measures of cash. Moreover, we show that exogenous CEO turnover resulting in appointments of single (married) CEOs increases (decreases) cash holdings. Additional results show that single‐CEO firms practise a more conservative payout policy and save more cash from operating and financing cash flows. Consistent with agency theory, single CEOs extract more compensation from the accumulated cash, leading to a lower value of cash holdings. External corporate governance mechanisms mitigate the relationship between single CEOs and cash holdings. Our results show that single‐CEO firms are more prone to agency problems.

Published: May 2023

AbstractBackgroundBreast cancer (BC) has been studied more and more in modern medicine. Circ_0002496 has established a critical role in BC. MiR‐433‐3p can exert important activity in cancer. YWHAZ can participate in BC development, but the targeting relationship among the three variables and its influence on the related process of BC are not clear.MethodsRT‐qPCR was used to analyze circ_0002496, miR‐433‐3p, and YWHAZ expression. Immunoblotting was used to analyze YWHAZ, Bax, Bcl‐2, and PI3K/AKT‐related proteins. RNase R assay was used to verify the ring structure of circ_0002496. Cell phenotypes were tested by Cell Counting Kit 8, EdU, sphere formation, tube formation, and flow cytometry assays.ResultsCirc_0002496 was enhanced and MiR‐433‐3p was downregulated in BC, while the expression of YWHAZ was higher in BC. Circ_0002496 targeted miR‐433‐3p and miR‐433‐3p targeted YWHAZ in BC cells. Depletion of circ_0002496 influenced the BC process, but miR‐433‐3p inhibitor reversed the impact of si‐circ_0002496 on the BC process. Re‐expression of YWHAZ weakened the influence of miR‐433‐3p on the BC process. Depletion of circ_0002496 could astrict tumor growth in vivo. Moreover, the circ_0002496/miR‐433‐3p/YWHAZ axis mediated the activation of the PI3K/AKT signaling pathway.ConclusionCirc_0002496 participated in the malignant procession of BC by miR‐433‐3p/YWHAZ regulation cascade.

Published: May 2023

AbstractBackgroundBreast cancer 1 (BRCA1) and breast cancer 2 (BRCA2) tumor suppressor genes play crucial roles in DNA repair and regulation of transcription. Mutations in these genes are closely associated with the occurrence of cancers. However, the mutation status of BRCA gene in central south Chinese lung cancer patients remains unclear, and its expression levels in lung cancer also need to be further explored.MethodsIn this study, we use next‐generation sequencing (NGS) technology to analyze the BRCA genes mutations in 462 central south Chinese lung cancer patients. Public databases including cBioportal, Catalogue Of Somatic Mutations In Cancer (COSMIC), The Cancer Genome Atlas (TCGA), Human Protein Atlas (HPA) and Expression Profiling Interactive Analysis (GEPIA) are also applied to explore the expression level and mutation status of BRCA in lung cancer patients and their relationships with the prognosis.ResultsWe found that the mutation rate of BRCA1/2 in central south Chinese lung cancer patients is 4.3% and 6.5% respectively, and missense mutations account for the majority in both BRCA1/2, which are similar to the international status of BRCA1/2 from public databases. In addition, 45 novel mutations of BRCA1/2 in lung cancer are reported in this study. Furthermore, we find that the BRCA2 mutations are negatively correlated with overall survival rate in lung cancer using cBioportal. Last, we demonstrate that both of the mRNA and protein levels of BRCA1/2 are upregulated in lung cancer, and the elevated mRNA expression levels are positively linked with poor prognosis.ConclusionIn general, our study better complements knowledge of the BRCA1/2 mutation status in the Chinese lung cancer patients, and firstly reveals the association between BRCA1/2 expression levels and prognosis of lung cancer patients, which may provide great value for the early diagnosis and clinical treatment of lung cancer.

Published: May 2023

AbstractBackgroundIdentifying the preoperative risk factors for lymph node upstaging could contribute to the development of individualized perioperative treatment for patients with non‐small cell lung cancer (NSCLC). The current study aimed to evaluate the risk factors for lymph node upstaging, including gene mutation and programmed death ligand‐1 expression in patients with resectable NSCLC.MethodsData on the clinicopathological characteristics of patients who underwent lobectomy for clinical N0 NSCLC at our institution were collected. The clinicopathological findings of the pathological N0 and lymph node upstaging groups were then analyzed. Univariate and multivariate analyses were performed to examine the predictive factors for nodal upstaging.ResultsOf 291 patients, 40 had postoperative nodal upstaging (n = 25, N1; n = 15, N2). Large tumor size and high maximum standardized uptake value were significantly associated with nodal upstaging. The nodal upstaging group had a higher proportion of patients with solid adenocarcinoma and lymphatic, vascular, and pleural invasion than the pathological N0 group. Further, the nodal upstaging group had a higher proportion of patients with positive programmed death ligand‐1 expression than the pathological N0 group. Univariate and multivariate analyses showed that tumor size and positive programmed death ligand‐1 expression were associated with nodal upstaging.ConclusionThe appropriate therapeutic strategy including preoperative treatment and resection should be cautiously considered preoperatively in patients with clinical N0 NSCLC who have large tumors and positive programmed death ligand‐1 expression.
Morphometric analysis of the mandible of ram and ewe romanov sheep (Ovis aries) with 3D modelling: A CT study
Authors: İşbilir Fatma , Güzel Barış Can 
Published: May 2023

Abstract2D images view hardly measurement points due to the overlap of anatomical features. This challenge is overcome by 3D modelling. In particular, images obtained by computed tomography are converted into 3D models through certain software. In sheep breeds with high polymorphism, some changes have occurred in their morphology due to both environmental and genetic factors. In this context, determining the osteometric measurements of sheep and revealing breed‐specific characteristics provide very important data for forensic, zooarchaeological, and developmental sciences. Mandibular reconstruction measurements are used to reveal differences between species and between sexes and for treatment and surgery in many fields of medicine. In the present study, morphometric characteristics were determined by 3D modelling from computed tomography images obtained from mandibles of Romanov ram and ewe. For this purpose, mandibles of 16 Romanov sheep (eight females and eight males) were used. They were scanned using a 64‐detector MDCT device at 80 kV, 200 MA, 639 mGY, and 0.625 mm slice thickness. CT scans were recorded in DICOM format. Reconstructions of the images were made using a special software program. Volume and surface area measurements were made with 22 osteometric parameters of the mandible. GOC‐ID had a statistically significant positive correlation with GOC‐ID, PC‐ID, GOC‐MTR, GOC‐PTW, GOC‐FMN, PMU, MDU, PDU, DU, GOV‐PC, GOV‐IMD, MTR‐MH, MO‐MH, FMN‐ ID, BM, MG, and CG (p < 0.01). GOC‐ID had a statistically significant correlation with MTR‐ID, GOV‐CR, PTW‐MH and SI (p < 0.05). When the CR‐PC measurement point was examined, it was observed that it had no statistically significant correlation with all measurement points (p > 0.05). As a result of the measurement, it was found that the volume and surface areas were higher in rams than in ewes. The morphometric data obtained would be a reference income in the fields of zoo‐archaeology, anatomy, forensics, anaesthesia, surgery, and treatment.

Authors: Kasiga Teresa , Bro Tomas 
Published: May 2023

AbstractPurposeThe objective of this study was to determine the current Swedish epidemiology of sport‐related eye injuries and to analyse the effect of the increased popularity of the racquet sport padel.MethodsThis was a retrospective, register‐based, cohort study of medical records in the county of Jönköping, Sweden. All individuals with a sports‐related eye injury needing healthcare between January 2017 and December 2021 were included. For these individuals, data about background, consequences and treatment of the injuries were obtained.ResultsDuring the 5‐year study period, 255 patients sought care for sports‐related eye injuries at the ophthalmological clinics in Jönköping County. Floorball caused the largest proportion of eye injuries (39%) followed by padel (20%) and football (15%). However, the proportion of injuries caused by padel increased during the study period to be the dominating cause in 2021. Compared to floorball, patients with eye injuries from padel were older and had female gender to a higher extent. The ball caused almost all injuries from padel; the majority occurred in the right eye. Most the eye injuries from padel were mild or moderate but 4% had severe consequences with an imminent risk of long‐term complications.ConclusionsIn a short time period, padel has become the leading cause of sports‐related eye injuries in Sweden. To reduce the number of eye injuries, protective eyewear could be recommended.

AbstractIntroductionPrescriber behaviour is important for understanding opioid use patterns. We described variations in practitioner‐level opioid prescribing in New South Wales, Australia (2013–2018).MethodsWe quantified opioid prescribing patterns among medical practitioners using population‐level dispensing claims data, and used partitioning around medoids to identify clusters of practitioners who prescribe opioids based on prescribing patterns and patient characteristics identified from linked dispensing claims, hospitalisations and mortality data.ResultsThe number of opioid prescribers ranged from 20,179 in 2013 to 23,408 in 2018. The top 1% of practitioners prescribed 15% of all oral morphine equivalent (OME) milligrams dispensed annually, with a median of 1382 OME grams (interquartile range [IQR], 1234–1654) per practitioner; the bottom 50% prescribed 1% of OMEs dispensed, with a median of 0.9 OME grams (IQR 0.2–2.6). Based on 63.6% of practitioners with ≥10 patients filling opioid prescriptions in 2018, we identified four distinct practitioner clusters. The largest cluster prescribed multiple analgesic medicines for older patients (23.7% of practitioners) accounted for 76.7% of all OMEs dispensed and comprised 93.0% of the top 1% of practitioners by opioid volume dispensed. The cluster prescribing analgesics for younger patients with high rates of surgery (18.7% of practitioners) prescribed only 1.6% of OMEs. The remaining two clusters comprised 21.2% of prescribers and 20.9% of OMEs dispensed.Discussion and ConclusionWe observed substantial variation in opioid prescribing among practitioners, clustered around four general patterns. We did not assess appropriateness but some prescribing patterns are concerning. Our findings provide insights for targeted interventions to curb potentially harmful practices.

Published: May 2023

AbstractIntroductionNew dental graduates' (NDGs) transition to professional practice is an important landmark and developmental stage in their career and in the UK it is supported by a formal educational transition process through a one‐year salaried practice‐based programme. However, little is known about graduates' experiences during this period. As part of a larger mixed‐methods project, this study aimed to explore NDGs' experiences during their transition to professional practice, represented by Vocational Dental Practice.Materials and MethodsSixty‐six NDGs from one dental school were invited to participate. Two rounds of in‐depth interviews were conducted: Interview 1 upon NDGs' graduation and then Interview 2 was a follow‐up interview after they had spent six‐nine months in vocational dental training (VDT). At Interview 1, a subset of participants agreed to record longitudinal audio‐diaries (LADs) and continued these for 6–9 months into VDT. Data from the interviews and LADs were analysed together using a thematic analysis approach.ResultsEleven of the 66 invited NDGs agreed to be interviewed at Interview 1 (16.6%), seven at Interview2 (10.6%), and six (9.2%) recorded LADs. Four topic summaries were developed around NDGs transition experiences: (1) conceptualisation of the process; (2) responses to the transition, (3) challenges and support and (4) relationships with stakeholders.ConclusionNDGs' transition to professional practice was perceived as exciting and rewarding on personal and professional levels but carried challenges. VDT and related stakeholders play a vital role of supporting NDGs into their new professional life.
