The perfect storm in the midst of a pandemic: the use of information within an institution's concurrent crises
Authors: R Slagle Derek , McIntyre J.J. , Chatham-Carpenter April , Reed Heather Ann 
Published: February 2021

PurposeThe purpose of this study is to examine the types of information that were shared by the institution, and faculty/staff responses to the information shared, with the goal of providing recommendations for other institutions facing concurrent crises.Design/methodology/approachThis mixed-methods case study examines a public university's experiences managing the Covid-19 pandemic crisis while simultaneously navigating financial challenges that had been building over time. Using data from university-wide mediated communications and a survey of on-campus stakeholders during the Covid-19 pandemic and university retrenchment process, this paper explores institutional communication, stakeholder response to organizational communication and faculty/staff reactions to information in the midst of concurrent crises.FindingsThe study found that the university used instructing and advising information within its messages from its top administrator but fell short of incorporating empathy for its stakeholders in its initial responses.Research limitations/implicationsUsing the situational crisis communication theory (Coombs, 2019), which recommends the use of an ethical base response to crises, implications are provided for other organizations facing concurrent crises during the Covid-19 pandemic, to also incorporate empathy in their messages to stakeholders whose livelihoods are being affected, across multiple platforms.Originality/valueWeathering the Covid-19 pandemic and long-term financial pitfalls have proven to be a disruptive phenomenon for higher education institutions. This research expands understanding of institutional communication and stakeholder reactions in a higher education institution facing both the Covid-19 crisis and a retrenchment.Peer reviewThe peer-review history for this article is available at:https://publons.com/publon/10.1108/OIR-09-2020-0415.

AbstractObjectiveTo investigate the intersection of race and economic context in treatment with hysterectomy among reproductive aged women with noncancerous gynecologic conditions.Data SourcesWe combined administrative billing records of inpatient and outpatient hysterectomy procedures (N = 28 301) occurring in North Carolina between 2011 and 2014 with census data to calculate county‐level hysterectomy rates.Study DesignSpatial analysis techniques examined the distribution of black and white hysterectomy rates across counties, and county‐level black and white rate differences were compared across economic contexts.Data Collection/ExtractionWe restricted to those of premenopausal age identifying as non‐Hispanic black or white, undergoing hysterectomy for nonemergent causes (N = 28 301 procedures).Principal FindingsCounty‐level hysterectomy rates were spatially patterned (Moran's I, P < .05) and similarly so for black and white women (LISA, P < .005). The black‐white difference in hysterectomy rates was the largest in the high economic tier counties (22/10 000 person‐years [PY], P < .05) and smallest in the mid and low economic tier counties (11/10 000 PY, P > .05 and 10/10 000 PY, P > .05, respectively).ConclusionSocioeconomic context is important to understand, particularly for black‐white disparities in hysterectomy. Efforts should be made to understand the causes of higher rates of hysterectomy among blacks than whites, especially in counties in the highest economic tier.

AbstractBecause of their early divergence in insect evolution, unique aquatic larval stage, and low dispersal ability, many mayfly species exhibit genetic structures that accurately reflect geological history and paleoclimatic changes. The present study investigated the genetic characteristics of Ecdyonurus yoshidae Takahashi (Ephemeroptera: Heptageniidae), a mayfly that inhabits a variety of freshwater habitats in Japan. Mitochondrial cytochrome c oxidase subunit I (COI) and 16S ribosomal RNA (16S rRNA) gene sequences were generated from 209 mayfly specimens that were collected from 109 sites in Japan. A total of 145 haplotypes were detected, and nine of the lineages exhibited geographical regionality, with one lineage being endemic to Lake Biwa. The haplotype network was “bottleneck type” and included both star‐like structures and missing (or unobserved) haplotypes. Together, the haplotype network and FST values indicated that the Fukuejima Island group (Clade I) was genetically distinct from groups on the island of Kyushu, which is separated from Fukuejima Island by the Gotonada Sea. The common ancestor of E. yoshidae lineages in Japan was estimated to have diverged 1.14 mega‐annum (Ma) (95% highest posterior density interval, 0.55–1.78 Ma), and more regional genetic diversities were generated during the Middle to Late Pleistocene. Genetically distinct lineages of eastern and western Japan were separated by the Kinki Triangle region in central Japan. The genetic diversity of the habitat generalist E. yoshidae increased during the Middle and Late Pleistocene, when crustal movement and climate change in the Japanese archipelago occurred simultaneously.
Development of a new low‐cost device to measure calcium carbonate content, reactive surface area in solid samples and dissolved inorganic carbon content in water samples

Abstract

Estimates of soil carbonate dynamics are still very scarce, despite their importance in the global carbon budget. Geochemical models used to estimate carbonate precipitation–dissolution rates require important inputs including carbonate content and calcite reactive surface area in soil as well as dissolved inorganic carbon (DIC) content in soil solution. However, most methods currently available to accurately measure these parameters can be time‐consuming and/or often require expensive laboratory equipment.

To tackle this problem, we aimed to develop a sensitive device to measure these variables at low cost and with little time investment. By taking advantage of the recent development of low‐cost CO2 sensors and microcontrollers, a low‐cost and easy‐to‐mount analyzer was developed based on direct measurements of CO2 evolved during an acidic reaction.

The new instrument proved to be sensitive, accurate, precise and able to quickly perform the analyses. It was therefore used in a pilot experiment on the inorganic component of CO2 flows from crusted semi‐arid soils, and to evaluate the variation in DIC content through a spring‐cave‐downstream river water continuum.

The device could facilitate these analyses for scientists from different fields since it can potentially analyse any solid or aqueous sample.

Published: February 2021

AbstractPurposeTo validate the content of the nursing diagnosis proposal Disturbed thought process.MethodsWith an exploratory and descriptive design, the content validation for each component of the diagnosis proposal was pursued, based on a previous broad conceptual work, through consulting experts, applying Fehring's Diagnosis Content Validation Model. The modified Delphi technique was used by sending out three rounds of questionnaires electronically to seek consensus among the experts.FindingsThe nursing diagnosis version validated in this study includes the diagnosis label Disturbed thought process, the corresponding definition, 15 defining characteristics, and 13 related factors. The resulting diagnosis total Diagnosis Content Validation score was 0.99, implying its content validation.ConclusionsThe validated diagnosis proposal describes a human response for which nursing professionals can autonomously assess and prescribe interventions leading to improvement of this health problem and/or alleviate its consequences, preserving the patient's autonomy and helping them to address their situation. It will be included in the next edition of the nursing diagnosis classification NANDA‐I 2021–2023.Implications for Nursing PracticeThe results of this study will help nursing professionals reduce the potential impact among patients who suffer from an alteration in cognitive functioning in its executive function dimension, as the validated diagnosis proposal will make it possible to identify and report this problem precisely.

AbstractBackgroundTeens who delay driving licensure may not be subject to graduated driver licensing restrictions that are known to reduce crash risk. We explored the association of delay in licensure with driving while impaired (DWI) and riding with an impaired driver (RWI) among emerging adults.MethodsData from the NEXT Generation Health Study, starting with 10th grade (2009–2010), were analyzed. The outcome variables were Wave 7 (W7) self‐reported DWI and RWI as dichotomous variables. The independent variable was delay in licensure. Covariates included sex, urbanicity, race/ethnicity, family structure, parent education, family affluence, teen’s highest education, minimum legal drinking age laws, and onset age of alcohol use. Descriptive analysis and logistic regressions were conducted.ResultsOf 2525 participants eligible for licensure, 887 reported a delay in licensure by 1–2 years (38.9%, weighted) and 1078 by > 2 years (30.3% weighted) across 7 waves. In W7, 23.5% (weighted and hereafter, 5.6% once, 17.8% ≥twice) of participants reported DWI and 32.42% (5.6% once, 25.4% ≥twice) reported RWI. Logistic regressions showed no overall significant association of delay in licensure with either W7 RWI or W7 DWI. However, in stratified analyses, among African American youth, delay in licensure was positively associated with DWI (OR = 2.41, p = 0.03) and RWI (OR = 2.72, p = 0.05). Among those with ≤ high school or lower education by W7, delayed licensure was positively associated with RWI (OR = 2.51, p < 0.01).ConclusionsWhile in the overall sample, delayed licensure did not appear to be associated with DWI or RWI, our findings suggest that delayed licensure may be of concern to teen risk of DWI and RWI among African Americans and among those with lower educational attainment. Furthermore, as two‐thirds of youth delayed licensure, more research is needed to determine whether this is more of a positive (i.e., protective) factor by reducing their exposure to crash risk or a negative (i.e., risk) factor due to their missing important driver safety stages of graduated driver licensing.
Financial reporting and corporate innovation: a review of the international literature
Authors: Huang Hedy Jiaying , Habib Ahsan , Sun Sophia Li , Liu Ying , Guo Huiting 
Published: February 2021

AbstractWe synthesise the empirical studies on innovation in the accounting, finance, and corporate governance disciplines using Bushman and Smith’s corporate transparency framework as our theoretical lens. The review presents competing findings on the association between financial reporting and innovation. Most of the reviewed studies fail to address the critical question of how the financial reporting system affects the interactions among financial development, corporate governance and innovation. We suggest future research, ranging from enriching the theoretical perspectives to incorporating the future of innovation research in the COVID‐19 environment.
Tunnelling in asset‐injecting private placements: evidence from China
Authors: Zhang Weidong , Wang Jenny Jing , Luo Guomin , Sun Yanqi 
Published: February 2021

AbstractFollowing the reform of shareholder structures in China, the country’s listed companies have seen a boom in asset injection using private equity placements. However, because of continuing weaknesses in corporate governance structures and accounting regulations on related‐party transactions, it is possible for controlling shareholders to ‘tunnel’ listed companies through unsound private placements. We find that manipulation of the discount rate offered in private placements, accompanied by earnings management behaviour, is used by controlling shareholders to ‘tunnel’ listed companies during the private placement and asset‐injecting process.
Molecular systematics and biogeography of an Australian soil‐burrowing cockroach with polymorphic males, Geoscapheus dilatatus (Blattodea: Blaberidae)

Published: February 2021

AbstractAn iconic group of arid‐adapted insects is the Australian soil‐burrowing cockroaches (Blaberidae: Geoscapheinae), large, wingless insects that evolved burrowing behaviour and associated forms in parallel from wood feeding ancestors in the subfamily Panesthiinae. A particularly problematic taxon within the Geoscapheinae is Geoscapheus dilatatus (Saussure, 1864), which might represent a species complex and whose delimitation has been complicated for decades by the species harbouring polymorphic males. Males can be divided into two main morphs: individuals possessing horn‐like protrusions on the anterior margin of the pronotum (‘tuberculate’) and those without these characters (‘non‐tuberculate’). A less common, third form consists of individuals that possess tubercles but are far larger than other tuberculate males and occur solely to the north of the species' distribution (‘atypical’ tuberculates). Here, we make use of whole mitochondrial genomes and nuclear ribosomal RNA data from individuals across the range of G. dilatatus to conduct the first phylogenetic analysis of this species to date. We recover all tuberculate males (including atypical forms) as monophyletic and the derived form of G. dilatatus, having evolved only once in this species, whereas non‐tuberculate forms are paraphyletic. Fossil‐calibrated molecular clock analysis revealed that the divergence between these two forms occurred during the late Miocene approximately 6.7 Mya, concurrent with an expansion of the continent's drier biomes. Environmental niche modelling suggests that tuberculate male forms are more climatically tolerant than their more restricted non‐tuberculate counterparts, and both forms' predicted fundamental niches are strongly limited by rainfall. Three species delimitation analyses implemented here failed to consistently delimit G. dilatatus beyond a single species. Ultimately, population genetic approaches paired with additional sampling will be necessary to determine these findings more concretely, but at present, we do not consider the results presented here sufficient to delimit G. dilatatus based on morphological differences found in the species' polymorphic males alone.

AbstractAimThis study assessed lifestyle‐related risk factors for cardiovascular disease in young women with Turner syndrome.MethodsIn 2012, we sent a questionnaire to women with Turner syndrome aged ≥18 years and living in Switzerland with questions on socio‐demographic and medical data as well as health behaviour. We compared the reported lifestyle with that of women from the Swiss Health Survey 2012, a representative survey of the general population.ResultsFifty‐seven per cent (45/79) of women with Turner syndrome answered the questionnaire (mean age: 24 years). Eighty per cent (36/45) had never smoked compared with 58% (1156/1972) of the general population (p < 0.01). Women with Turner syndrome engaged less often in binge drinking (34% vs. 71%) (p < 0.001), but consumed alcohol equally often as the general population (p = 0.327). They performed sports as often as the general population (p = 0.34), but only one quarter (11/45) of women with Turner syndrome adhered to official physical activity recommendations.ConclusionAlthough most women with Turner syndrome had a healthy lifestyle, only a minority had sufficient physical activity. Paediatricians should promote structured physical activity in girls with Turner syndrome from early childhood onwards to reduce their cardiovascular risk in adulthood and to increase long‐term health‐related quality of life.

SummaryClonal haematopoiesis (CH) in patients with acute myeloid leukaemia (AML) may persist beyond attaining complete remission. From a consecutive cohort of 67 patients with nucleophosmin 1‐mutated (NPM1mut) AML, we identified 50 who achieved NPM1mut clearance and had parallel multicolour flow cytometry (MFC) and next generation sequencing (NGS). In total, 13 (26%) cleared all mutations, 37 (74%) had persistent CH frequently involving DNA methyltransferase 3α (DNMT3A,70%), tet methylcytosine dioxygenase 2 (TET2, 27%), isocitrate dehydrogenase 2 (IDH2, 19%) and IDH1 (11%). A small number (<1%) of aberrant CD34+ myeloblasts, but immunophenotypically different from original AML blasts [herein referred to as a pre‐leukaemic (PL) phenotype], was detected in 17 (49%) patients with CH, but not in any patients with complete clearance of all mutations (P = 0·0037). A PL phenotype was associated with higher mutation burden (P = 0·005). Persistent IDH2 and serine and arginine‐rich splicing factor 2 (SRSF2) mutations were exclusively observed in PL+ CH+ cases (P = 0·016). Persistent dysplasia was seen exclusively in cases with a PL+ phenotype (29% vs. none; P = 0·04). The PL+ phenotype did not correlate with age, intensity of induction therapy or relapse‐free survival. Post‐remission CH in the setting of NPM1mut clearance is common and may result in immunophenotypic changes in myeloid progenitors. It is important to not misinterpret these cells as AML measurable residual disease (MRD).

Published: February 2021

AbstractObjectiveTurner syndrome (TS) is a congenital disease characterized by delayed puberty, ovarian dysgenesis and short stature. Although most patients are diagnosed with primary amenorrhea, approximately 15‐20% of patients with TS are reported to have spontaneous menarche. However, little is known about their menstruation status after spontaneous menarche. In the current study, we investigated the menstrual abnormalities after spontaneous menarche in TS patients.DesignRetrospective study.PatientsThis study included TS patients with spontaneous menarche at Osaka Police Hospital or Komura Women’s Clinic between April 2015 and December 2019.MeasurementsData regarding the age of menarche, menstruation status and chromosomal karyotype were collected and retrospectively analyzed.ResultsOf 172 TS patients, 32 with spontaneous menarche were identified. The median age of menarche was 12 years old. Premature ovarian insufficiency (POI) after menarche was observed in 12 patients (37.5%) and the median age at menopause was 20 years old. The average period from spontaneous menarche to menopause in these patients was 5.1 years. Five patients (15.6%) had irregular menstruation and 15 (46.9%) had regular menstruation. When examined according to the structural abnormality of the X chromosome, all patients with structural abnormality of the X chromosome were diagnosed with POI after spontaneous menarche, and none with mosaic without structural abnormality were diagnosed with POI.ConclusionApproximately one‐third of TS patients with spontaneous menarche were diagnosed with POI after menarche for an average of 5.1 years. Counseling is required for TS patients and their parents, including information about menstrual abnormalities or fertility preservation.

AbstractBackgroundSurgical templates are classified as noncritical devices, and they do not need to be sterile.AimPrimary aim of this study was to assess the microbiological burden present on the surgical templates without metallic sleeves after disinfection. Furthermore, to evaluate trueness after disinfection and steam sterilization at 121°C/15 min, and over a 8‐week storage period. Finally, to assess their accuracy after in vitro implant placement simulation.Materials and methodsForty surgical templates were printed and divided in five groups of eight templates each. Groups A to C were disinfected with 0.5% Chlorhexidine Gluconate and 70% ethyl alcohol base solution for 15 min. Templates in the group D were steam sterilized at 121°C for 15 min, while, the templates in the group E were used as control. Implant simulation was performed in the group A. Outcome measures were determination of bioburden, trueness assessment using GOM Inspect Professional software, and accuracy evaluated thought the mean angular deviation of simulated implants.ResultsTotal microbic charge measured as colony forming units (CFU) for sample, was 24.40 in the control group (group E; n = 8), and <4.40 in the test group (group C; n = 8), with a reduction of 84%. Colored representation from GOM inspection showed no differences after disinfection and implant simulation, disinfection alone, and steam sterilization, compared to the control group. A very small difference in the surface and volume dimensions was reported 1 month after templates fabrication. The mean roundness tolerances of the tested templates improved of 0.96 ± 0.56° (95% CI 0.57–1.35).ConclusionSurgical templates without metallic sleeves can be safely used after disinfection, demonstrating high level of accuracy, even when the surgical procedures should be postponed within a couple of weeks. Further in vivo study are needed to confirm these preliminary results.
