Diversity climate and workplace belongingness as organizational facilitators of tacit knowledge sharing

Purpose The purpose of this study is to examine the relationship between diversity climate and tacit knowledge sharing and the mediating role of workplace belongingness between them. Design/methodology/approach The sample for this study consists of 495 employees (52.1% male, n = 258) drawn from varied occupational groups. Data were collected online using existing self-report measures. Hypotheses were tested with ordinary least squares regression-based path analysis. Findings This study provides evidence that diversity climate is positively related to workplace belongingness and tacit knowledge sharing. Furthermore, workplace belongingness is positively related to tacit knowledge sharing. Finally, workplace belongingness mediates the relationship between diversity climate and tacit knowledge sharing. Practical implications The findings highlight the need for organizations to promote fair human resource (HR) policies and practices by enacting and judiciously implementing policies that promote inclusiveness and fair treatment to stand a chance of benefiting from employees’ tacit knowledge sharing. Originality/value This study builds on existing research but shifts the focus to the influence of diversity climate on tacit knowledge sharing and thus sets up a precedent for subsequent research in this area. This study is, therefore, the first to attempt to link diversity climate to tacit knowledge sharing through workplace belongingness.
How do people perceive flood risk? Findings from a public survey in Tuscany, Italy

The study of risk perception (RP) has much increased in the last years to improve flood risk management. Effective communication requires an understanding of how the risk of flooding is perceived by residents of different areas. In this work, RP is investigated through a survey involving 483 people living in Tuscany. RP was assessed through a score built on four items covering personal, residence, and sociodemographic variables concerning flood RP. Results showed that: (a) flood RP was moderate; (b) RP was positively correlated with age, higher education, proximity to a river and direct experience; (c) people who experienced floods felt themselves to be more informed and prepared; (d) subjectively perceived risk and experts' risk assessment seemed generally correlated, even if people living in areas at “high risk” tend to underestimate the actual flood risk level; (e) the majority of the respondents considered the government and themselves as equally responsible for personal preparedness; and (f) less than 20% was aware of a Local Emergency Plan. The need of focusing on people living in the riskiest areas with targeted communication campaigns on risk awareness, hazard preparedness, and other implications of the findings in terms of communication strategies are discussed.
Evaluation of disease, yield and economics associated with fungicide timing in Canadian Western Red Spring wheat

Abstract: Protection from fungal plant pathogens is key for optimizing the yield and quality of wheat (Triticum aestivum L.). However, current grower practices and historical research do not always align with respect to optimum fungicide timing to maximize disease control, yield, quality, and profitability of Canadian Western Red Spring (CWRS) wheat. Six fungicide treatments were evaluated at eight site–years across Alberta in 2018 and 2019 to determine the optimum time for fungicide application. The treatments included early fungicide applications at BBCH 22–23 (herbicide timing), early- to mid-season application at BBCH 30–32 (plant growth regulator timing), ‘traditional’ timing at BBCH 39–45 (flag leaf), and head timing at BBCH 61–63 (Fusarium head blight timing) and were compared with a non-treated control. Yield responses to fungicide treatments occurred at 50% of the site–years when disease pressure was 32% higher than in non-responsive site–years. Responsive site–years were characterized by higher relative humidity (65.4%–74.0%) and an average 273 mm of precipitation. At responsive site–years, McFadden leaf spot disease severity ratings were 50% greater in early August when fungicides were applied at BBCH 22–23 and 30–32 versus at BBCH 39–45. At responsive sites, yield and thousand-kernel weight were 9.3% and 5.2%, higher, respectively, for fungicide applications at BBCH 39–45 and BBCH 61–63 compared with fungicide applications at BBCH 22–23 and BBCH 30–32. The most economically beneficial practices were applications of propiconazole, benzovindiflupyr and azoxystrobin (Trivapro A+B) at BBCH 39–45 or prothioconazole and tebuconazole (Prosaro XTR) at BBCH 61–63 when environmental conditions were conducive for disease development.
Application of Ann for Prediction of Chloride Penetration Resistance and Concrete Compressive Strength

The purpose of this paper is to present Artificial Neural Network (ANN) models to predict compressive strength and chloride penetration levels of self-consolidating concrete (SCC) mixes. The ANN models used to predict chloride penetration resistance were developed using input variables including the ratio of water to binder (w/b), and the contents of coarse aggregate, fine aggregate, fly ash, and silica fume. For prediction of concrete compressive strength, the fundamental ANN parameters considered include w/b ratio, the amount of High Range Water Reducing (HRWR) admixture, and the contents of coarse aggregates, fine aggregates, silica fume, and fly ash. Compressive strength data from published literature was used to train the developed ANN and successful models were validated using compressive strength data tested by the investigators. The trained ANN was able to predict compressive strength and chloride iron penetration levels successfully.
Comparative Analysis of the Nutritive Value of Smoked, Dried Procambarus clarkii (Freshwater Crayfish) from Three Nigerian States

The nutritive value of smoked, dried Procambarus clarkii sourced from Akwa Ibom, Rivers and Lagos states of Nigeria were evaluated and compared. The proximate composition of the crayfish samples were determined using official methods of analysis, mineral composition were determined using Atomic Absorption Spectrophotometer and the amino acid composition were analysed using Amino Acid Analyser. The proximate composition of the crayfish samples from three different locations (Akwa Ibom, Lagos and Rivers states) such as moisture, crude protein, crude fat and ash contents showed significant difference (p<0.05) across the selected locations while crude fibre and carbohydrate content showed no significant difference (p<0.05) across the selected locations. The amino acids composition gave the crayfish sample from Akwa Ibom state as the richest source of essential amino acids. The mineral contents of the crayfish samples such as potassium, phosphorus, magnesium, manganese and calcium showed significant difference (p<0.05) across Original Research Article Omole et al.;AJFAR, 11(3): 39-45, 2021; Article no.AJFAR. 65106 40 the selected locations while calcium, zinc and sodium contents showed no significant difference (p<0.05) across the selected locations. Comparing their nutrient component, smoked, dried P. Clarkia from Awka Ibom state possess the richest nutritive value.
An Assessment of Ambient Water Quality and Challenges with Access to Water and Sanitation Services for Individuals Experiencing Homelessness in Riverine Encampments

Individuals experiencing unsheltered homelessness face significant barriers to accessing water, sanitation, and hygiene services, but the risks associated with this lack of access and barriers to service provision have been largely understudied. We analyzed water samples upstream and downstream of three homeless encampments in the San Diego River watershed and interviewed service providers from public and nonprofit sectors to assess local perceptions about challenges and potential solutions for water and sanitation service provision in this context. Water upstream from encampments contained detectable levels of caffeine and sucralose. Escherichia coli concentrations downstream of the encampments were significantly greater than concentrations upstream, but there was no significant change in the concentrations of other pollutants, including caffeine and sucralose. The HF183 marker of Bacteroides was only detected in one sample upstream of an encampment and was not detected downstream. Overall, there was insufficient evidence to suggest that the encampments studied here were responsible for contributing pollution to the river. Nevertheless, the presence of caffeine, sucralose, and HF183 indicated that there are anthropogenic sources of contamination in the river during dry weather and potential risks associated with the use of this water by encampment residents. Interviews with service providers revealed perceptions that the provision of water and sanitation services for this population would be prohibitively expensive. Interviewees also reported perceptions that most riverbank residents avoided contact with service providers, which may present challenges for the provision of water and sanitation service unless trust is first built between service providers and residents of riverine encampments.
Perturbation‐based null hypothesis tests with an application to Clayton models

Null hypothesis tests are popularly used when there is no appropriate alternative hypothesis available, especially in model assessment, where the assumed model is evaluated with no model being considered an alternative. Motivated by a test for Clayton models in multivariate survival analysis, we propose a perturbation‐based method for null hypothesis testing that makes use of the resampling approach in Jin et al. (Jin et al., Biometrika; 2001; 88, 381–390) to estimate the variance–covariance matrix of an estimator to avoid intractable variance estimation. The proposed tests are straightforward and theoretically justified. We apply the proposed method to modify the tests in Shih (Shih, Biometrika; 1998; 85, 189–200) for the assessment of Clayton models. The proposed tests present satisfactory performance in simulation studies. A colon cancer dataset further illustrates the proposed tests.
Innovation in Mathematics Learning on Students with Disabilities in Asia: Literature Review

The literature review is aimed to analyze research regarding innovative mathematics learning in Asia. The research utilizes six articles discussing five media innovation learning in Indonesia and one instructional innovation learning in Malaysia. The results of the study shows that media learning innovation preferred to be implemented in the Mathematics classroom rather than instructional innovation learning. Furthermore, the students with the disability who usually appear as a subject are mentally retarded students, hearing impaired/deaf students, and students with learning disabilities.
Profiling the New Zealand police physical appraisal test

PurposeThe aims of this study were to evaluate fitness levels in a cohort of police trainees and compare these results to other police trainees and the general population.Design/methodology/approachRetrospective data for 274 male and 152 female police trainees were supplied. Measures included height, body mass and physical appraisal test (PAT; 2.4 km run, vertical jump, push-ups and grip strength) results, assessed twice, prior to commencement of training, separated by several months. Wilcoxon signed rank tests were used to analyze non-parametric initial and final PAT scores and Mann–Whiney U tests were used to determine variance between groups.FindingsMale trainees were significantly quicker in the run (−12%, p < 0.001), completed more push-ups (+74%, p < 0.001) with greater grip strength (+52% left and +50% right, p < 0.001) when compared to female trainees. Following the second PAT assessment, the significant differences between male and female trainees remained (p < 0.001). Only female trainee 2.4 km run times improved significantly between initial and final PAT (−4%, p = 0.002). Originality/valueWhen compared to the general population from which they were drawn and to other law enforcement trainees, the police trainees in this study were quicker, more powerful and stronger. While there was no loss of fitness between initial and final PAT performance, a conditioning program, spanning the periods between initial and final PAT may be of benefit to increase fitness prior to training commencement especially for female trainees who were generally less fit than, yet must complete the same training as, male trainees.
RTK Inhibitors in Melanoma: From Bench to Bedside

Simple Summary Receptor tyrosine kinases (RTKs) have long been demonstrated to play key roles in melanoma development. RTK activation requires dimerization and intracellular tyrosine trans-phosphorylation leading to downstream signaling pathways activation. As RTKs show different structures, mechanism of activation could differ. In this review, we will discuss the structure and specific mechanism of activation of each RTK, and its alteration associated with stage of the disease. Additionally, we summarize the effect of RTK inhibitors tested in preclinical and clinical melanoma studies indicating the reason, the reported results, and the rational approaches for combination strategies based on RTK inhibition in melanoma. Abstract MAPK (mitogen activated protein kinase) and PI3K/AKT (Phosphatidylinositol-3-Kinase and Protein Kinase B) pathways play a key role in melanoma progression and metastasis that are regulated by receptor tyrosine kinases (RTKs). Although RTKs are mutated in a small percentage of melanomas, several receptors were found up regulated/altered in various stages of melanoma initiation, progression, or metastasis. Targeting RTKs remains a significant challenge in melanoma, due to their variable expression across different melanoma stages of progression and among melanoma subtypes that consequently affect response to treatment and disease progression. In this review, we discuss in details the activation mechanism of several key RTKs: type III: c-KIT (mast/stem cell growth factor receptor); type I: EGFR (Epidermal growth factor receptor); type VIII: HGFR (hepatocyte growth factor receptor); type V: VEGFR (Vascular endothelial growth factor), structure variants, the function of their structural domains, and their alteration and its association with melanoma initiation and progression. Furthermore, several RTK inhibitors targeting the same receptor were tested alone or in combination with other therapies, yielding variable responses among different melanoma groups. Here, we classified RTK inhibitors by families and summarized all tested drugs in melanoma indicating the rationale behind the use of these drugs in each melanoma subgroups from preclinical studies to clinical trials with a specific focus on their purpose of treatment, resulted effect, and outcomes.
Nurturing mutual gains in the public sector: the roles of socially responsible human resource practices, employee use of normative public values, and job crafting

ABSTRACT The aim of our inquiry is to investigate how and when socially responsible human resource practices (SRHR practices) foster service performance and psychological health among public sector employees. The participants for this research were recruited from wards (local level governments) in Vietnam. The data from the participants were analysed through multilevel structural equation modelling. The results lent credence to the positive relationships between SRHR practices and employees’ service performance as well as psychological health via the mediating role of job crafting. SRHR practices were more positively associated with job crafting when employee use of normative public values was lower.
The Ameliorative Effects of L-Carnitine against Cisplatin-Induced Gonadal Toxicity in Rats

Cisplatin (CP) is a highly efficient remedy in cancer treatment, but it adversely affects the testicular tissue. This work assessed the ameliorative efficacy of Lcarnitine (LC) against CP induced oxidative stress in rat testis, via investigating testosterone level and tissue oxidative/antioxidant parameters, histological alterations, and immunohistochemical expressions of intermediate filaments (IFs) proteins; vimentin (VIM) and cytokeratin 18 (CK18). Twenty-eight rats were assigned into four groups (7 rats each) as follows; groups I and II received saline and LC (100 mg/kg b.wt.) respectively orally once daily for 30 days; group III were injected with a single dose of CP (7.5 mg/kg, IP), 27 days after starting the experiment. Group IV received both LC and CP. Injection of CP significantly decreased serum testosterone and glutathione reductase and catalase in the testicular tissues and elevated malondialdehyde. Histologically, testes of the CP treated group revealed marked degenerative changes. Also, overexpression of both VIM and CK18 in testicular tissues were recorded. However, the administration of LC with CP restored the biochemical parameters, histological and immunohistochemical pictures towards the normalcy. Accordingly, LC is recommended as a supplement with chemotherapy to ameliorate its oxidative stress. This is the first study investigating the immunohistochemical expressions of IFs proteins, VIM and CK18, following administration of LC as a protective agent against CP induced testicular toxicity in rats
COVID-19 public awareness: association with social media use and development of a scoring tool ‘COVID-PAS'

ABSTRACT Background Coronavirus disease 2019 (COVID-19) was declared as a pandemic by the World Health Organization, raising concern among the general population, and urging them to seek information. Raising awareness and providing essential medical information to broad audiences could be achieved through social media. Methods We employed a cross-sectional survey design in Lebanon via phone calls. Participants were selected by simple random sampling, using a computer-based random number generator. The questionnaire was composed of 3 sections: Socio-demographics, awareness on COVID-19, and social media use assessment. Awareness was assessed using 30 questions forming the COVID-19 Public Awareness Score (COVID-PAS), and social media use was assessed using questions about participants’ daily usage duration and platforms used. Results A total of 641 participants with a mean age of 49.03 ± 15.36 were included in the study. Their COVID-PAS mean was 21.9 ± 3.8, and 561 (87.5%) were social media users. WhatsApp® and Facebook® were the most used. Multiple linear regression showed that higher educational level (P < 0.001), higher income (P < 0.001), and social media use (P < 0.001) were associated with better scores, while older age (P = 0.001) was associated with lower scores. Radio use (P = 0.01) and information from religious leaders (P < 0.001) were associated with lower scores only in the bivariate analysis. Conclusions In general, the Lebanese population had a good awareness of COVID-19. Social media users had a significantly higher awareness score than the non-users, but there remains a need to further explore the aspects of social media use that affect their awareness.
Type one diabetes and autoimmune-related conditions: a Portuguese research in pediatric age

Background. Type 1 diabetes (T1D) is the most common chronic metabolic disease among children and the autoimmune process can induce the development of additional autoimmune diseases. We performed a retrospective study of the clinical records and analytical determinations of pediatric patients with T1D during a five-year-period. Methods. We identify 102 patients, similar gender distribution. In 98% was performed, at least, one tracking of other autoimmune disease. We found positive autoantibodies in 31%: thyroid antibodies (n = 16), antibodies for celiac disease (n = 10), and antinuclear antibodies (n = 5). Antibodies positivity occurred in mean 3.6 years after T1D diagnosis. Other conditions associated were pulmonary hemosiderosis, vitiligo, IgA deficit, uveitis, and positive Anti-Saccharomyces cerevisiae antibodies. Conclusions. Despite the antibodies’ positivity we highlight the possibility of other less common autoimmune-related conditions. The screening of comor-bidities is fundamental to perform an earlier diagnosis and prevent complications.
What's wrong with the Australian River Assessment System (AUSRIVAS)?

The Australian River Assessment System (AUSRIVAS or AusRivAS) is a national biomonitoring scheme that supposedly assesses the ‘biological health’ of rivers. AUSRIVAS outputs observed-over-expected (O/E) indices derived from macroinvertebrate survey data obtained both at a site to be assessed and at designated reference sites. However, AUSRIVAS reference sites lack any consistent or quantified status, and, therefore, AUSRIVAS O/E indices have no particular meaning. Moreover, many studies have found AUSRIVAS O/E to be a weak or inconsistent indicator of exposure to anthropogenic or human-influenced stressors. Poor performance by AUSRIVAS may relate to numerous factors including the following: (1) variable reference-site status, (2) inappropriate model predictors, (3) limitations of O/E indices, (4) inconstant sampling methods, and (5) neglect of non-seasonal temporal variability. The indices Ephemeroptera–Plecoptera–Trichoptera (EPT) and stream invertebrate grade number – average level (SIGNAL) provide alternatives that have often outperformed AUSRIVAS O/E in comparative tests. In addition, bioassessment of Australian rivers might be advanced by the development of diagnostic methods to identify the stressors causing ecological impact rather than merely to infer impact intensity and assign quality ratings to assessment sites.
