Why organizations fail to share knowledge: an empirical investigation and opportunities for improvement
Authors: Israilidis John , Siachou Evangelia , Kelly Stephen 
Published: September 2020

PurposeThis paper explores critical failure factors (CFFs) in the context of knowledge sharing. It provides further insights into what can cause knowledge- sharing failures, inflexible knowledge-sharing strategies and ineffective knowledge- sharing mechanisms. It also examines how practitioners can reduce or even mitigate such dysfunctions.Design/methodology/approachA case-based inductive approach was conducted. Data were collected from two studies applying mixed methods. The first data set included nine in-depth, semi-structured interviews with highly skilled personnel from an aerospace and defense organization. The second data source included 375 successfully completed questionnaires from participants employed at the same organization.FindingsThe paper identifies six CFFs with an impact on knowledge sharing. It also reveals that managing organizational ignorance can play a key role in generating new knowledge and averting failure. Study findings provide insights into the importance of identifying these failures when sharing knowledge and propose relevant mitigation strategies.Originality/valueThis paper identifies a range of empirically validated CFFs that complement the extant work on the complexity of knowledge sharing and have hitherto not been seen in the literature. It also provides a more nuanced understanding of why both organizations and their people often fail to share knowledge by exploring the role of organizational ignorance.
Teleworking in Portuguese communities during the COVID-19 pandemic
Authors: Tavares Fernando , Santos Eulália , Diogo Ana , Ratten Vanessa 
Published: September 2020

Purpose
Human beings spend about a third of their day working, so it is very important that they are integrated into a good community work environment. When the setting is teleworking in a family and housing context, it is important to keep a good environment and also a good physical, psychological and ergonomic aspects to attain job performance. The purpose of this paper is to characterize teleworking carried out in Portuguese communities in the context of the state of emergency caused by the COVID-19 pandemic.

Design/methodology/approach
A survey questionnaire was used, which analyzed general information about teleworking and the individual’s adaptation process and the difficulties they faced during the teleworking period. The sample consists of 359 individuals aged 18 years or over, who were teleworking in their homes and in a family environment.

Findings
The results show that adapting to teleworking was easy or very easy and that it happened very quickly. The main difficulties encountered by the individuals were the lack of professional interaction/communication with coworkers, the lack of resources related to support infrastructures, such as the internet or a printer, and the reconciliation of teleworking with family life/household chores/dedication to children and time/schedule management.

Originality/value
This study hopes to contribute to the increase of the scientific knowledge in the teleworking field and to allow companies to rethink the teleworking strategies to optimize resources and costs and to improve the organization’s productivity without harming the quality of life and well-being of their workers.
“What's next? Calling beer-drinking a sport?!”: virtual resistance to considering eSport as sport
Authors: Tjønndal Anne 
Published: September 2020

PurposeThe purpose of this paper is to study virtual resistance towards the introduction of Norway's first professional eSport league in the category of sport video games (SVGs), Eserien – the professional FIFA league and its inclusion in the Norwegian Football Federation.Design/methodology/approachA qualitative content analysis of texts published from the first season of Eserien was launched (December 2018) and during the first season of Eserien (April 2019 to December 2019) in Norwegian online spaces. Based on this approach, a total of 23 texts were subjected to a qualitative content analysis. The theoretical framework for the analysis of the material is Guttmann's (1978/2004) characteristics of modern sport and processes of sportification, as well as conceptualizations of the sport-health ideology in national and international sport policies today.FindingsThe arguments made against the inclusion of the professional FIFA league Eserien as part of the Norwegian Football Federation revolves around three main themes: (1) eSport as something unhealthy and inactive, (2) issues of cheating and match fixing in professional eSports and (3) threats professionalized eSport poses for traditional football clubs and players in terms of securing sponsorship and gaining media attention.Research limitations/implicationsA limitation is the small sample size consisting of data from the first season of the first professional FIFA league organized by a Norwegian governing sport body. More research is needed to support the results found here, and readers should be careful to transfer the findings from this study to other sporting contexts.Originality/valueThis study is an empirical exploration of resistance towards eSport expressed by traditional sport fans. These insights expand on existing sport management research on spectators, commercialization and professionalization of eSport.
Interorganizational learning in the tourism industry: conceptualizing a multi-level typology
Authors: Buhagiar Kristina 
Published: September 2020

Purpose
While the importance of interorganizational learning (IOL) as a resource for strategic renewal has been acknowledged in research, limited attention has been placed on exploring IOL in complex networks or ecosystems. This paper aims to bridge this gap in literature through conceptualizing IOL in the tourism industry at the micro, meso and macro levels of the ecosystem.

Design/methodology/approach
This paper applies a narrative literature review to explore the tourism industry and IOL. Through insights which evolved from literature, exploratory typologies and propositions were developed forming the basis of the multi-level typology of interorganizational learning in the tourism industry.

Findings
Based on the multi-level typology of interorganizational learning in the tourism industry, market actors may develop in isolation, in clusters or networks, with the aggregate output of these formations constituting the basis of the tourism ecosystem. Within the multi-layers of the tourism ecosystem, IOL may be subdivided into seven distinct typologies, with learning ranging from active, passive, interactive to asymmetric. Each typology of IOL is subsequently influenced by relational ties, which may range from collaborative to competitive, and power distribution, which may lead to symmetric or asymmetric relationships.

Originality/value
The novelty of this paper lies in an ecosystem perspective of IOL in the tourism industry, outlining the multi-level nature of IOL in a destination.

Published: September 2020

SummarySerendipita vermiferassp.bescii, hereafter referred to asS. bescii, is a root‐associated fungus that promotes plant growth in both its native switchgrass host and a variety of monocots and dicots. Winter wheat (Triticum aestivumL.), a dual‐purpose crop, used for both forage and grain production, significantly contributes to the agricultural economies of the Southern Great Plains, USA. In this study, we investigated the influence ofS. besciion growth and transcriptome regulation of nitrogen (N) and phosphorus (P) metabolism in winter wheat.Serendipita besciisignificantly improved lateral root growth and forage biomass under a limited N or P regime. Further,S. besciiactivated sets of host genes regulating N and P starvation responses. These genes include, root‐specific auxin transport, strigolactone and gibberellin biosynthesis, degradation of phospholipids and biosynthesis of glycerolipid, downregulation of ammonium transport and nitrate assimilation, restriction of protein degradation by autophagy and subsequent N remobilization. All these genes are hypothesized to regulate acquisition, assimilation and remobilization of N and P. Based on transcriptional level gene regulation and physiological responses to N or P limitation, we suggestS. besciiplays a critical role in modulating stress imposed by limitation of these two critical nutrients in winter wheat.

Published: September 2020

AbstractPregnancy rate of women decreases with age due to declining quality of oocytes and embryos. However, there is no established method to improve pregnancy rate in aging women. In this study, we identified a senescence‐associated secretory phenotype (SASP) factor partially responsible for the decline in embryo implantation potential. Based on microarray analysis using young and aging human embryos at the same morphological grade, 702 genes showed >fivefold increases in aging human blastocysts. Among these genes, C‐X‐C motif chemokine 5 (CXCL5) showed 7.7‐fold increases in aging human blastocysts. However, no‐age‐dependent changes in expression of the CXCR2, the cognate receptor for CXCL5, were found. In aging mice, Cxcl5 transcript levels were also increased in oocytes and embryos. Treatment of young mouse embryos with CXCL5 decreased implantation rates, together with increased expression of aging markers (P53, P21, Pai‐1, and Il‐6). Moreover, CXCL5 treatment suppressed trophoblast outgrowth in young mouse blastocysts. Conversely, suppression of CXCL5‐CXCR2 signaling in aging mouse embryos using neutralizing antibodies and a receptor antagonist improved the implantation rate, leading to increases in pregnancy and delivery of normal pups. The gene expression pattern of these embryos was comparable to that in young mouse embryos showing enriched cell proliferation‐related pathways. In conclusion, we identified CXCL5 as a SASP factor in human and mouse embryos and suppression of CXCL5‐CXCR2 signaling during embryo culture improved pregnancy success in aging mice. Future analysis on CXCL5‐CXCR2 signaling suppression in human embryos could be the basis to improve embryo development and pregnancy outcome in middle‐aged infertile patients.

AbstractA large body of preclinical research has shown that neuroimmunity plays a key role in the deleterious effects of alcohol (ethanol) to the brain. Translational imaging techniques are needed to monitor the efficacy of strategies to prevent or mitigate neuroinflammation and alleviate ethanol‐induced neurotoxicity. Opioid receptor antagonists such as nalmefene are antagonists of the toll‐like receptor 4, which may block the proinflammatory signaling cascade induced by ethanol at this specific target. Male adolescent rats received a validated protocol of ethanol injection (i.p, 3 g/kg daily for two consecutive days followed by two resting days) during 14 days. Positron emission tomography (PET) imaging with the translocator protein 18 kDa (TSPO) radioligand [18F]DPA‐714 was performed at day‐15. Toxicity induced by repeated binge‐like ethanol exposure (71% mortality) was drastically reduced by nalmefene pretreatment (0.4 mg/kg, 14% mortality). No mortality was observed in animals that received vehicle (control) or nalmefene alone. Compared with control animals (n = 10), a significant 2.8‐fold to 4.6‐fold increase in the volume of distribution (VT) of [18F]DPA‐714 was observed among brain regions in animals exposed to ethanol only (n = 9). Pretreatment with nalmefene significantly alleviated the neuroimmune response to ethanol exposure in all brain regions (1.2‐fold to 2.5‐fold increase in VT; n = 5). Nalmefene alone (n = 6) did not impact [18F]DPA‐714 VT compared with the control group. Nalmefene may protect against the neuroinflammatory response and overall toxicity associated with binge drinking. [18F]DPA‐714 PET imaging can be used to noninvasively address the neuroimmune impact of ethanol exposure and its modulation by pharmacological strategies in vivo, with translational perspectives.
Measuring price discovery between nearby and deferred contracts in storable and nonstorable commodity futures markets
Authors: Hu Zhepeng , Mallory Mindy , Serra Teresa , Garcia Philip 
Published: September 2020

AbstractUsing price discovery measures, including Putniņš’ (2013) information leadership share and intraday data, we quantify the proportional contribution of nearby and deferred contracts in price discovery in the corn and live cattle futures markets. On average, nearby contracts reflect information more quickly than deferred contracts in the corn market, but have a relatively less dominant role in the live cattle market. In both markets, the nearby contract loses dominance when its relative volume share dips below 50%, which typically occurs when the nearby is close to maturity. Regression results indicate that the share of price discovery is mainly related to trading volume and time to expiration in both markets. In the corn market, price discovery share between nearby and deferred contracts is also related to inverse carrying charges, crop year differences, USDA announcements, market crashes, and commodity index position rolls. Differences between corn and live cattle markets are consistent with differences in the contracts’ liquidity and commodity storability.
Adjuvant electrochemotherapy after debulking in canine bone osteosarcoma infiltration

Published: September 2020

AbstractOsteosarcoma is a bone cancer considered rare to humans, but common in dogs. Dogs and humans share genetic homology and environmental risk factors. Improving the treatment of osteosarcoma in dogs could also be relevant to improve procedures in humans. Traditional treatments of osteosarcoma involve surgery and chemotherapy. Such treatments are commonly aggressive and not possible for many patients. Electrochemotherapy emerges as a minimally invasive, effective, and safe treatment alternative. Electrochemotherapy combines applications of high‐intensity electric fields during short periods with anti‐cancer drugs to improve its medicine cytotoxicity. Analyzing the electric field distribution, as well as electric current density, are essential to electrochemotherapy success. This paper brings the first case of a canine osteosarcoma treatment performed with bleomycin and electrochemotherapy. We performed in silico studies with finite element method software to observe the electric field distribution. In silico experiments help to verify possibilities and limitations of treating bone destruction and macro or micro tumor infiltrations around the primary tumor mass. Results show that both needle or plate electrodes are feasible to remove the tumor even with invasion into the bone. Plate electrodes perform well in treating micro infiltrations when associated with conductive gel and direct contact between electrode and bone (without soft tissues). Needle electrodes are effective in treating tumor infiltration on external cortical bone. Multiple applications are needed to cover all cranium layers with sufficient electric field intensity. Electrochemotherapy protocol with needle or plate electrodes does not present sufficient electric current density capable of affecting brain tissue, even in cases of bone destruction.
Dehumanization of Scheduled Castes and Scheduled Tribes (SC/ST): Evidence from Implicit, Moderate, and Blatant Measures
Authors: N. A. Baby Ziliya , Manjaly Jaison A. 
Published: September 2020

AbstractEvidence for perceptual bias toward the Scheduled Caste/Scheduled Tribes (SC/ST)—a community historically oppressed and treated as untouchables in India—was found through a series of studies. We hypothesized that the SC/ST are perceived as less human in comparison to the dominant castes (General Category), leading to adverse consequences to the dehumanized group. Studies were designed to measure the effect of Caste on social perception by including participants belonging to General and SC/ST categories. Study 1 used an implicit association test and found that SC/ST are subjected to subtle dehumanization. Study 2 extended the findings using a moderately explicit measure of dehumanization and the results indicated biased perception of humanness in the SC/ST targets, albeit a valence effect. Study 3 demonstrated blatant dehumanization of SC/ST using an explicit measure. Overall the results indicate the dehumanization of the marginalized community that can have implications on attitudes and behaviors toward them.

Published: September 2020

AbstractThe aim of this study was to examine whether ultrasonography can be used to predict the outcome of clinical mastitis in dairy cows. Forty‐seven mastitic quarters of Holstein‐Friesian cows were examined using ultrasonography at the time of the first examination. In mastitic mammary tissue, three sonographic signs indicating tissue abnormality were found: a hyperechoic spot in the parenchyma area, structural changes to the milk duct, and non‐homogeneous parenchyma. Logistic regression was used to evaluate whether the abnormal findings in the sonographic images can be used to predict the outcome of clinical mastitis. The outcomes of clinical mastitis were defined by the return, or failure to return, to marketable milk production. The sonogram finding of non‐homogeneous parenchyma in the first examination did predict the outcome of clinical mastitis, whereas the type of systemic symptoms (severe or moderate) was not a predictor in this regression model. Therefore, ultrasound examinations of mammary glands in the first examination could be a useful method for predicting outcome of clinical mastitis. There is an economic benefit if ultrasound examination in first examination helps in the decision of whether or not to treat the mastitic cows.

Published: September 2020

AbstractIntroductionCardiovascular disease (CVD) is exceedingly prevalent, and occurs prematurely in individuals with bipolar disorder (BD). Cardiorespiratory fitness (CRF), arguably the most important modifiable CVD risk factor, is also associated with brain structure and function. There is a gap in knowledge regarding CRF in BD, particularly in relation to brain structure.MethodsAdolescents with BD (n = 54) and healthy controls (HC; n = 53) completed semi‐structured diagnostic interviews, self‐report questionnaires, and 20 minutes of cardiorespiratory exercise at 60‐80% of estimated maximum heart rate (HR) on a bicycle ergometer. Average power (watts/kg) within this HR range served as a previously validated proxy for CRF. Brain magnetic resonance imaging (MRI) structural analysis was done using FreeSurfer. Analyses controlled for age and sex.ResultsCRF was significantly lower in BD vs HC (0.91 ± 0.32 vs 1.01 ± 0.30, p = 0.03, F = 4.66, df=1, η2=0.04). Within BD, greater depression symptoms were associated with lower CRF (P = .02), and greater physical activity (PA) was associated with greater CRF (P < .001). In multivariable analyses, there were significant main effects of diagnosis (HC>BD; P = .03) and sex (M > F; P < .001) on power. Significant predictors of power within BD included male sex (P = .02) and PA (P = .002) but not depression symptoms (P = .29). Significant diagnosis by CRF interaction effects was found in frontal, parietal, and occipital cortical regions.ConclusionCRF was reduced among adolescents with BD, particularly women, related in part to depression symptoms and inactivity and was differentially associated with regional brain structure. Studies seeking to improve CRF as a means of reducing psychiatric symptoms of BD are warranted.
Semiparametric models and inference for the effect of a treatment when the outcome is nonnegative with clumping at zero
Authors: Cheng Jing , Small Dylan S. 
Published: September 2020

AbstractThe outcome in a randomized experiment is sometimes nonnegative with a clump of observations at zero and continuously distributed positive values. One widely used model for a nonnegative outcome with a clump at zero is the Tobit model, which assumes that the treatment has a shift effect on the distribution of a normally distributed latent variable and the observed outcome is the maximum of the latent variable and zero. We develop a class of semiparametric models and inference procedures that extend the Tobit model in two useful directions. First, we consider more flexible models for the treatment effect than the shift effect of the Tobit model; for example, our models allow for the treatment to have a larger in magnitude effect for upper quantiles. Second, we make semiparametric inferences using empirical likelihood that allow the underlying latent variable to have any distribution, unlike the original Tobit model that assumes the latent variable is normally distributed. We apply our approach to data from the RAND Health Insurance Experiment. We also extend our approach to observational studies in which treatment assignment is strongly ignorable.
