Strategizing with organizational videoblogs: sensegiving, self-branding or spectacle?
Authors: Krohn Mikaela 
Published: May 2019

Purpose
Despite the increased interest in video methods and the role of visuality in organizations and management, the use of video in organizations has received scant attention. The purpose of this paper is to explore organizational videoblogs as a phenomenon, and discuss avenues that open up for qualitative research. The paper examines the affordances of organizational videoblogs in a strategy context by contrasting them with more conventional corporate videos, in order to discuss how spectacularization and social media style communication is influencing social practices in organizations.

Design/methodology/approach
First, this paper introduces the phenomenon of organizational videoblogging and its implications for research. Second, it engages in a theoretical discussion on videoblogs as a strategizing activity, through three different analytical lenses: strategic sensegiving, strategic self-branding and strategy as spectacle. Illustrative empirical examples are used to support the theoretical discussion.

Findings
The paper argues that organizational videoblogging is a phenomenon that changes social practices in organizations by injecting a visual, social media type communication. Organizational videoblogs emphasize authenticity and provide new affordances for sensegiving and self-branding in strategizing, but ultimately lead us to ask whether they risk turning strategizing into an infotainment-like spectacle.

Originality/value
The value of this paper lies in conceptualizing how and why organizational videoblogs can be studied in organizations. The paper provides future research with vocabulary and characteristics to distinguish different types of video in organizations.
Client industry characteristics and auditor changes
Authors: Cairney Tim , Stewart Errol G. 
Published: May 2019

Purpose
This study aims to examine whether the industry characteristics of homogeneity, product competition, high auditor competition and accounting standards complexity are associated with auditor changes.

Design/methodology/approach
Logistic regressions test for significance of the industry characteristics on resignations, dismissals and directional changes to and from Big 4 and nonBig 4 auditors after controlling for client, auditor and engagement factors.

Findings
The authors report a lower likelihood of auditor resignations with greater accounting standards complexity. The authors also report a greater likelihood of auditor dismissals with greater industry homogeneity, greater product competition and greater auditor competition. Results also show that accounting standards complexity is associated with a lower likelihood of changes from Big to nonBig auditors, and industry homogeneity is associated with a greater likelihood of changes from Big to nonBig. Also, greater auditor competition is associated with a lower likelihood of changes from nonBig to Big auditors.

Research limitations/implications
Prior research has established the importance of industry characteristics to the market for audit services (Cairney and Stewart, 2015; Wang and Chui, 2015; Cahan et al., 2011; Bills et al., 2015). The authors report that industry characteristics also impact auditor changes. Second, previous research has used various methods that indicate general industry effects on changes. The paper contributes to this research by specifying industry characteristics. Limitations include the reliance on the self-reporting in 8-Ks to identify auditors resigning and firms dismissing auditors. Also, the paper relies on proxies for industry characteristics that were developed in prior research.

Practical implications
Regulators have expressed concern over the relatively low rates of auditor changes and the problem of lack of auditor choice. By demonstrating a significant effect of industry characteristics on changes, the authors indicate some levers that may be available to influence rates of auditor changes, especially realignments to nonBig.

Originality/value
This is one of the first studies to examine how specific industry characteristics impact auditor changes. The study may be of interest to academics who are interested in how industry factors influence auditor changes. It may also interest policymakers who could lever the characteristics of industries to address concerns about the low rates of auditor changes.

SummarySoils provide a heterogeneous environment varying in space and time; consequently, the biodiversity of soil microorganisms also differs spatially and temporally. For soil microbes tightly associated with plant roots, such as arbuscular mycorrhizal fungi (AMF), the diversity of plant partners and seasonal variability in trophic exchanges between the symbionts introduce additional heterogeneity. To clarify the impact of such heterogeneity, we investigated spatiotemporal variation in AMF diversity on a plot scale (10 × 10 m) in a grassland managed at low intensity in southwest Germany. AMF diversity was determined using 18S rDNA pyrosequencing analysis of 360 soil samples taken at six time points within a year. We observed high AMF alpha‐ and beta‐diversity across the plot and at all investigated time points. Relationships were detected between spatiotemporal variation in AMF OTU richness and plant species richness, root biomass, minimal changes in soil texture and pH. The plot was characterized by high AMF turnover rates with a positive spatiotemporal relationship for AMF beta‐diversity. However, environmental variables explained only ≈20% of the variation in AMF communities. This indicates that the observed spatiotemporal richness and community variability of AMF was largely independent of the abiotic environment, but related to plant properties and the cooccurring microbiome.
Interim Effective Tax Rate Estimates and Internal Control Quality
Authors: McGuire Sean T. , Neuman Stevanie S. , Rice Sarah C. 
Published: May 2019

ABSTRACTThis study examines whether the volatility of interim estimates of the annual effective tax rate (ETR) provides ex ante information about the quality of firms' internal control environments. Recent research suggests that some firms selectively disclose internal control weaknesses (ICWs). Given the negative consequences associated with ICWs, it is important for capital market participants to be able to identify firms with ineffective internal controls in a timely manner. We find that firms with more volatile annual ETR estimates are more likely to report both tax‐ and nontax‐related ICWs in the current year. Our results also indicate that the volatility of annual ETR estimates declines following the remediation of tax‐related ICWs, but not following the remediation of nontax‐related ICWs. In addition, we find that ETR volatility in the current year is associated with the likelihood that a firm will report an ICW in the following year. Finally, we provide evidence that the volatility of annual ETR estimates is associated with the likelihood that a firm has an undisclosed ICW. In combination, our results suggest that the volatility of interim estimates of the annual ETR provides an ex ante signal of the likelihood that a firm's internal controls are ineffective.

AbstractAging is an independent risk factor for vascular diseases. Perivascular adipose tissue (PVAT), an active component of the vasculature, contributes to vascular dysfunction during aging. Identification of underlying cell types and their changes during aging may provide meaningful insights regarding the clinical relevance of aging‐related vascular diseases. Here, we take advantage of single‐cell RNA sequence to characterize the resident stromal cells in the PVAT (PVASCs) and identified different clusters between young and aged PVASCs. Bioinformatics analysis revealed decreased endothelial and brown adipogenic differentiation capacities of PVASCs during aging, which contributed to neointimal hyperplasia after perivascular delivery to ligated carotid arteries. Mechanistically, in vitro and in vivo studies both suggested that aging‐induced loss of peroxisome proliferator‐activated receptor‐γ coactivator‐1 α (PGC1α) was a key regulator of decreased brown adipogenic differentiation in senescent PVASCs. We further demonstrated the existence of human PVASCs (hPVASCs) and overexpression of PGC1α improved hPVASC delivery‐induced vascular remodeling. Our finding emphasizes that differentiation capacities of PVASCs alter during aging and loss of PGC1α in aged PVASCs contributes to vascular remodeling via decreased brown adipogenic differentiation.
An examination of the Vietnamese emerging market economy: understanding how and why auditors have responded to the audit law reforms
Authors: Nguyen Phuong Thi , Kend Michael 
Published: May 2019

AbstractUsing New Institutional Sociology (NIS), we seek to explain the variation between what was intended with the Vietnamese reforms to audit in 2011 and the actual practice, and why there is variation. This paper reports findings from interviews with 70 individuals representing identified groups of stakeholders in the market for audit and assurance services in Vietnam. Overall, the findings indicate that there still exist business risks for foreign companies that pursue trade and commerce in communist Vietnam, particularly where non‐Big 4 audit firms are involved in the external audit function, as in some cases auditor independence is most likely compromised.

Published: May 2019

AbstractProblemIntrauterine microbial colonization and its association with the pathogenesis of endometriosis via an innate immune cascade have been reported. As a potential source of microbial transmission, information on microbial colonization in cervical mucus is unknown. We investigated pattern of microbiota in the cervical mucus collected from women with and without endometriosis using next‐generation sequencing (NGS) technology.Method of studyCervical mucus samples were collected from women with (n = 30) and without (n = 39) endometriosis. The communities of microbiota in cervical mucus in the endometriosis group and the control group were examined by Gram staining and NGS targeting the V5‐V6 region of 16S ribosomal RNA gene. Copy number of some target bacteria was detected by real‐time PCR.ResultsWe confirmed visual presence of bacteria in cervical mucus by Gram staining. NGS analysis showed that distribution of microbiota was similar in cervical mucus of women with and without endometriosis regardless of the phases of the menstrual cycle. In addition to predominant Lactobacilli spp., the populations of Corynebacterium, Enterobacteriaceae, Flavobacterium, Pseudomonas, and Streptococcus were increased in the endometriosis group. Of them, Enterobacteriaceae and Streptococcus were identified as the more significant candidates in the endometriosis group than in controls by real‐time PCR (P < 0.05 for each).ConclusionOur NGS analysis of cervical mucus indicated that among a variable microbiota, two candidates (Enterobacteriaceae and Streptococcus) were more frequently detected in women with endometriosis. Further investigation is needed to elucidate a mechanistic link of these bacteria in the pathophysiology of endometriosis.

BackgroundIn patients who are awake with normal mental and neurologic status, it has been suggested that the thoracolumbar (TL) spine may be cleared by clinical examination, irrespective of the mechanism of injury. The aim of this pilot study was to test the feasibility and accuracy of a clinical decision tool focused towards clearance of the TL spine during assessment of patients in the emergency department after trauma.MethodsA prospective interventional study was conducted at two major trauma centres. The intervention of a clinical decision tool for assessment of the TL spine was applied prospectively to all patients with subsequent imaging results acting as the comparator. The primary outcome variable was fracture of the thoracic or lumbar vertebra(e). The clinical decision tool was assessed using sensitivity and specificity for detecting a TL fracture and reported with 95% confidence intervals (CIs).ResultsThere were 188 cases included for analysis that all underwent imaging of the thoracic and/or lumbar vertebrae. There were 34 (18%) patients diagnosed with fractures of the thoracic and/or lumbar vertebrae. In this pilot study, sensitivity of the clinical decision tool was 100% (95% CI 87.3–100%) and specificity was 37.0% (95% CI 29.5–45.2%) for the detection of a thoracic or lumbar vertebral fracture.ConclusionsFeasibility of clinical clearance of the TL spine in two major trauma centres was demonstrated in a clinical study setting. Evaluation of this clinical decision tool in patients following blunt trauma, particularly in reducing imaging rates, is indicated using a larger prospective study.

Published: May 2019

AbstractPurposeTo study the genetic aetiology and phenotypes of retinal degeneration (RD) in Finnish children born during 1993–2009.MethodsChildren with retinal degeneration (N = 68) were investigated during 2012–2014 with a targeted gene analysis or a next‐generation sequencing (NGS) based gene panel. Also, a full clinical ophthalmological examination was performed.ResultsThe cohort covered 44% (68/153) of the Finnish children with inherited RD born 1993–2009. X‐linked retinoschisis, retinitis pigmentosa, Leber congenital amaurosis and cone–rod dystrophy were the most common clinical diagnoses in the study group. Pathogenic mutations were found in 17 retinal genes. The molecular genetic aetiology was identified in 77% of the patients (in 77% of the families) analysed by NGS method. Several founder mutations were detected including three novel founder mutations c.148delG in TULP1, c.2314C>R (p.Gln772Ter) in RPGRIP1 and c.533G>A (Trp178Ter) in TYR. We also confirmed the previous tentative finding of c.2944 + 1delG in GYCU2D being the most frequent cause of Leber congenital amaurosis (LCA) in Finland.ConclusionsGlobally, RD is genetically heterogeneous with over 260 disease genes reported so far. This was shown not to be the case in Finland, where the genetic aetiology of RD is caused by a small group of genes, due to several founder mutations that are enriched in the population. We found that X‐chromosomal retinoschisis constitutes the major group in Finnish paediatric RD population and is almost exclusively caused by two founder mutations. Several other founder mutations were detected including three novel founder mutations. All in all, the genetic aetiology of 77% of families was identified which is higher than previously reported from other populations, likely due to the specific genomic constitution of the Finns.
Mindsets are contagious: The social contagion of implicit theories of intelligence among classmates
Authors: King Ronnel B. 
Published: May 2019

BackgroundBeliefs about the malleability of intelligence (fixed or growth mindsets) are strongly influenced by teachers and parents. However, the social contagion of mindsets among one's classmates has not been given sufficient attention.AimsThis study aimed to examine the social contagion of mindsets among one's peers by investigating the relationship between classmates' mindsets and one's own mindset.SampleIn Study 1, 676 students nested within 19 classes were surveyed, and in Study 2, 848 students nested within 30 classes participated.MethodsStudents were surveyed across two time points 7 months apart. Multilevel modelling was used.ResultsThe mindset of one's classmates at Time 1 predicted one's own mindset at Time 2 even after adjusting for one's own Time 1 mindset. These effects held even after controlling for demographic variables, social desirability, and achievement goals.ConclusionThe current study provided evidence for the social contagion of mindsets. Theoretical and practical implications are discussed.
A moral panic over cats

Published: May 2019

AbstractSome conservationists believe that free‐ranging cats pose an enormous risk to biodiversity and public health and therefore should be eliminated from the landscape by any means necessary. They further claim that those who question the science or ethics behind their arguments are science deniers (merchants of doubt) seeking to mislead the public. As much as we share a commitment to conservation of biodiversity and wild nature, we believe these ideas are wrong and fuel an unwarranted moral panic over cats. Those who question the ecological or epidemiological status of cats are not science deniers, and it is a false analogy to compare them with corporate and right‐wing special interests that perpetrate disinformation campaigns over issues, such as smoking and climate change. There are good conservation and public‐health reasons and evidence to be skeptical that free‐ranging cats constitute a disaster for biodiversity and human health in all circumstances. Further, there are significant and largely unaddressed ethical and policy issues (e.g., the ethics and efficacy of lethal management) relative to how people ought to value and coexist with cats and native wildlife. Society is better served by a collaborative approach to produce better scientific and ethical knowledge about free‐ranging cats.
Human development and advocacy journalism: Analysis of low editorial coverage in Pakistan
Authors: Ahmad Kamboh Shafiq , Yousaf Muhammad 
Published: May 2019

AbstractContextDespite being a nuclear power, Pakistan does not have satisfactory human development indicators. The 2018 United Nations Development Programme (UNDP) Human Development Index (HDI) ranking places it at 150 out of 189 countries, the lowest in the region after Afghanistan.PurposeThis article examines advocacy journalism coverage of human development issues versus other issues in the contents of mainstream Pakistani newspapers and investigates the factors behind the inadequate space given to them. The study further explores the association between editorial and readers’ priorities.MethodsThe quantitative content analysis method is used to measure and compare the frequency of sample content in five categories coupled with qualitative in‐depth interviews with veteran journalists/academics to explain the factors that influence the editorial content.FindingsRather than use precious space to comment on social hardship and ultimately improve the country’s HDI value, editorial content is dominated by the discourse produced by the communication bureaucracies of powerful national and international establishments. Issues‐based policies of the state and political actors that do not concern human development, and warmongering and actual conflicts with India and Afghanistan, are given considerably greater coverage. Moreover, readers’ reactions to editorial content through Facebook Likes indicate a clear difference between editorial and readers’ priorities.Policy ImplicationsThe communication aspects of development programmes should actively feed editorial boards regarding current global development agendas to ensure sufficient coverage of their advocacy. It is imperative to make the UNESCO‐led syllabus Teaching Journalism for Sustainable Development an integral part of the country’s journalism curriculum. Relevant bodies should organize professional editorial training to raise awareness of how to use precious space wisely for the advocacy of development issues and how to be alert to the readers’ priority issues.
Biventricular contractility during exercise in adults with small, unrepaired atrial septal defects
Authors: Udholm Sebastian , Maagaard Marie , Nyboe Camilla , Hjortdal Vibeke E. 
Published: May 2019

AbstractBackgroundAdult patients with a small, unrepaired atrial septal defect (ASD) have higher mortality and increased risk of several comorbidities compared to general population. Further, reduced submaximal and peak exercise capacity was recently demonstrated in these patients. The mechanisms behind these findings remain unexplained and, therefore, biventricular contractility during exercise was assessed by evaluating the force–frequency relationship in the same group of patients.MethodsAdults patients with a small, unrepaired ASD and healthy age‐ and gender‐matched controls were examined using echocardiography during supine bicycle exercise. Continuous tissue velocity Doppler was used to evaluate isovolumetric acceleration (IVA) and systolic velocities during an incremental workload protocol. All data were analyzed post hoc in a blinded fashion.ResultsWe included 30 patients previously diagnosed with a small, unrepaired ASD (mean age 35 years, 63% female) and 25 controls (mean age 34 years, 64% female). Patients had similar values of IVA and systolic velocities at rest when compared with the healthy controls. Further, no differences in IVA was found at peak heart rate for neither the left ventricle (90 ± 39 vs 129 ± 68 cm/s2, P = 0.1547) nor the right ventricle (128 ± 56 vs 154 ± 56 cm/s2, 0.5691). There were no correlations between peak velocities and the lower exercise capacity previously reported in these patients.ConclusionAdult patients with a small, unrepaired ASD have normal biventricular contractility at rest and during exercise when compared with healthy peers. Consequently, the pathophysiological mechanisms behind the impaired exercise capacity previously demonstrated in these patients remains unknown and will be a target for future work.
