Organizational cynicism as a moderator variable between ethical leadership and counterwork productive behaviors

JEL Classification: M12, M19, M51, M54 DOI: 10.22495/cbv17i1art3 Ethical leadership (EL) aims to improve the positive behaviors of workers and achieve common goals between leaders and their subordinates by directing and nurturing from leaders to their subordinates, this is accomplished by establishing ethical standards in the workplace that clarify the relationship between them (Ng & Feldman, 2015; Hussain & Attiq, 2017; Qian & Jian, 2020). Therefore, this paper aimed to test the impact of ethical leadership on counterproductive work behaviors (CWBs) and test organizational cynicism’s (OC) moderating role between them. We applied in the study a stratified random sample of faculty members working in Egypt’s Sohag University. The researchers relied on the survey and analyzed the results using simple regression, hierarchical regression moderated analysis and simple slope analysis. The paper’s findings show that EL has a negative effect on CWBs and that OC modifies the negative relationship between EL and CWBs. Consequently, when compared to those workers who realize a low level of cynicism, there is a weaker relationship in respect of workers who realize a higher level of cynicism. Our findings help university officials to improve the faculty members’ perceptions of EL. In detailing this study’s findings, we discuss several conclusions regarding EL, CWBs and OC.
Effectiveness of neutrophil/lymphocyte, lymphocyte/MPV and platelet/MPV ratios in the classification and mortality prediction of acute stroke

Objective: The aim of this study is to investigate whether Neutrophil / lymphocyte (NLR), Lymphocyte / MPV (mean platelet volume) (LMR) and thrombocyte / MPV (PMR) ratios obtained from the complete blood count, can be used as an effective marker in acute stroke for determining the prognosis and subtype of stroke. Material and methods: Patients admitted to the emergency department with acute stroke symptoms between January 1, 2020 and December 31, 2020 were evaluated retrospectively. The patients were divided into two groups as hemorrhagic or ischemic cerebrovascular disease (CVD) according to the radiological findings. NLR, LMR and PMR ratios were calculated. The last diagnosis and hospitalization information were recorded and their 28-day mortality status was evaluated. Results: A total of 764 patients were included in the study. The median age of the patients included in the study was 68 (IQR 25-75: 59-78) and 404 (52.9%) of the patients were male. In the analysis performed; it was observed that the LMR, NLR and PMR levels were significantly different in those who developed mortality on the 28th day (p = 0.009), (p = 0.002), (p = 0.026). In addition, only the NLR level was found to be significantly different in the ischemic group (p <0.001). Conclusion: We think that in cases with stroke, NLR, LMR and PMR levels can be used in predicting the prognosis of this disease. Also, NLR is significantly higher in ischemic stroke, and also significant in terms of showing that CVD type is hemorrhagic or ischemic.

CIRCULAR ECONOMY AS A DRIVER OF SUSTAINABLE DEVELOPMENT OF UKRAINE

The article considers the model of circular economy and the possibility of its implementation in Ukraine. The authors explore the main aspects of the circular economy and the relationship with the goals of sustainable development. It is noted that the use of innovations and innovation systems is the basis of the circular economy, which will ensure the interdependence between the reduction of non-returnable waste and increase the use of reusable resources, will not improve the ecological and economic condition of the country. The article analyzes the economic content of methods and models of implementation of the circular economy by identifying their impact on the sustainability of economic and government systems. The generalization of world experience in the implemented concepts of the circular economy allowed us to identify 5 main circular business models: circular deliveries, resource recovery, platforms for exchange and sharing, product as a service. The article gives examples of implementation of the principles of circular economy in the production of world brands. Prerequisites and recommendations for the introduction of a circular economy in Ukraine are summarized. It is determined that the introduction of a circular economy is beneficial for the enterprise or company, for consumers, communities and the state as a whole. The advantages in the long run on optimization of material flows, opportunities to enter new markets, expand the scope of services, obtaining additional profits in the field of services are highlighted. The interrelation of business models of circular economy recommended for use in Ukraine is established. The article identifies further steps of the study, which will be aimed at building a model of circular economy, based on the experience of leading European countries, taking into account Ukrainian characteristics, as well as detailed performance criteria for companies implementing circular economy depending on the scope and size.
strategic decision-making process in family businesses in Cameroon

This research aims to highlight the factors having an influence on the role played by the Board of Directors in the strategic decision-making process of Family businesses in Cameroon. The data analyzed were collected from 46 family firms in the cities of Yaoundé, Douala, Bafoussam and Dschang. Using orderly logistic regression, our results indicate that the individual factors to the manager (age, level of training, professional experience) have a significant influence on the role played by the board of director in the Decision-Making Process. In fact, although the influence of the manager's age is negative, his level of training and professional experience positively influence the role played by the Board in the decision-making process. In addition, we found a significant and positive association between the decision-making process and the contextual factors (link of inbreeding, accumulation of function) in the company. These conclusions constitute the basis of a reflection on the profile of the ruling class of family businesses in Cameroon, making it possible to guarantee and ensure their performance and sustainability.
Determinants of commitment and opportunism of institutional investors’ behaviour: an empirical investigation on Robo-voting Phenomenon

Purpose of the paper: Recent research identifies a troubling number of institutional investors that automatically follow the advice of their proxy advisors so that they can prove to have complied with their fiduciary duties in a practice known as robo-voting. Therefore, our central research questions are: How could the characteristics of institutional investors affect robo-voting phenomenon? How could robo-voting phenomenon favour the creation of new opportunistic behaviour, changing the scope of shareholder engagement? Methodology: Our paper directly addresses these questions by using ANCOVA (Analysis of Covariance) to test the effect of characteristics of institutional investors on the dependent variable under study. We use a manually constructed sample of coverage information from 123 Annual General Meetings held by large Italian companies in the 4-year period 2015 to 2018 and the voting reports of three proxy advisors. Findings: We show that such voting based on robo-voting phenomenon is restricted to specific types of institutional investors and it may be highlighted as a negative aspect of a duty to ‘demonstrate’ engagement on the part of institutional investors. Specifically, this duty could depend on location, strategy and category of institutional investors. Research limits: We refer only to the Italian market and it may be considered as a peripheral market by investors. Practical implications: We argue that legal enforcement of the conceptual and operational spectrum of engagement duties currently sits uncomfortably upon institutional investors and proxy advisors. Originality of the paper: We think it is important to consider how to promote shareholder engagement in general in a European context and at the same time curb negative activism by some shareholders.
A 7-year Prospective Epidemiological Study of Acute Elbow Admissions to a Trauma Unit

Introduction: This study represents an analysis of data collected prospectively over a seven-year period to our trauma unit, to identify the epidemiological background behind the admissions of patients with acute elbow problems and to highlight the impact of these admissions on our trauma service. Method: Nearly 16,000 patients were included in our database. The admissions were initially categorized into A) fractures/dislocations or B) soft tissue trauma. The fractures/dislocations were then further classified by radiographic anatomical location, with data also collected on length of stay and operative management. In total 509 admissions were included in this study; 193 were paediatric cases and 316 were adults. This included 428 admissions with fractures/dislocations and 81 cases of soft tissue trauma. Conclusion: In conclusion, this data allows us to identify relative frequency of acute elbow conditions, including the incidence of common fracture patterns. These figures help to facilitate resource planning, such as expertise amongst personnel or the acquisition of equipment, including radial head replacement, elbow arthroplasty, and periarticular locking plates.
Application of Remotely Sensed Rainfall data in Rainfall –run-off Modelling

Rainfall runoff modelling in a river basin is vital for number of hydrologic application including water resources assessment. However, rainfall data from sparse gauging stations are usually inadequate for modelling which is a major concern in Tanzania. This study presents the results of comparison of Tropical Rainfall Measuring Mission (TRMM) satellite rainfall products at daily and monthly time-steps with ground stations rainfall data; and explores the possibility of using satellite rainfall data for rainfall runoff modelling in Pangani River Basin, Tanzania. Statistical analysis was carried out to find the correlation between the ground stations data and TRMM estimates. It was found that TRMM estimates at monthly scale compare reasonably well with ground stations data. Time series comparison was also done at daily and annual time scales. Monthly and annual time series compared well with coefficient of determination of 0.68 and 0.70, respectively. It was also found that areal rainfall comparison in the northern parts of the study area had poor results compared to the rest of areas. On the other hand, rainfall runoff modelling with ground stations data alone and TRMM data set alone was carried out using five RealTime River Flow Forecasting System models and then outputs combined by Models Outputs Combination Techniques. The results showed that ground stations data performed better during calibration period with coefficient of efficiency of 76.7%, 81.7% and 89.1% for Simple Average Method, Weight Average Method and Neural Network Method respectively. Simulation results using TRMM data were 59.8%, 73.5% and 76.8%. It can therefore be concluded that TRMM data are adequate and promising in hydrological modelling.
Post-Pandemic of Covid-19 and the Need for Transforming Education 5.0 in Afghanistan Higher Education

The study is proposed to investigate Education 5.0 and the higher education circumstances in Afghanistan. Today, the mission of education is changed, everything is just a click away, one can google the right answer, hence, and there is an urgent need for redefining the national educational objectives and establishing new goals that are aligned with the new norms. Indeed, 21-century learners are involved in teaching and learning that cooperates with their head, hearth, and hands. Therefore, the study utilized a qualitative critical document analysis using public records, personal documents, and physical evidence to build an authentic understanding of the on-going paradigm shifts in education and to provide practical potentials for transformation Education 5.0 in the Higher Education of Afghanistan. The data is analyzed based on the procedure of defining research questions, data collection, data transcriptions, coding, and identifying the themes. The result shows that an essentialist-curriculum of teaching and testing is used in Afghanistan. The assessment approaches are included 10% of class activity and attendance, 10% of assignments and projects, 20% of the mid-term exam, and 60% of the final exam which indicates exam-oriented education. The finding also highlights that the students' needs and the employability requirements of the 21-century are not considered in teaching and learning circumstances. In conclude, the study recommends the use of three categories of 21-century skills such as Learning Skills, Literacy Skills, and Life Skills to help educational institutions towards the transformation of Education 5.0. This contributes to preparing learners for the post-pandemic of Covid-19 and employability requirements of the 21-century marketplace.
CoinPrune: Shrinking Bitcoin’s Blockchain Retrospectively

Popular cryptocurrencies continue to face serious scalability issues due to their ever-growing blockchains. Thus, modern blockchain designs began to prune old blocks and rely on recent snapshots for their bootstrapping processes instead. Unfortunately, established systems are often considered incapable of adopting these improvements. In this work, we present CoinPrune, our block-pruning scheme with full Bitcoin compatibility, to revise this popular belief. CoinPrune bootstraps joining nodes via snapshots that are periodically created from Bitcoin’s set of unspent transaction outputs (UTXO set). Our scheme establishes trust in these snapshots by relying on CoinPrunesupporting miners to mutually reaffirm a snapshot’s correctness on the blockchain. This way, snapshots remain trustworthy even if adversaries attempt to tamper with them. Our scheme maintains its retrospective deployability by relying on positive feedback only, i.e., blocks containing invalid reaffirmations are not rejected, but invalid reaffirmations are outpaced by the benign ones created by an honest majority among CoinPrunesupporting miners. Already today, CoinPrune reduces the storage requirements for Bitcoin nodes by two orders of magnitude, as joining nodes need to fetch and process only 6 GiB instead of 271 GiB of data in our evaluation, reducing the synchronization time of powerful devices from currently 7 h to 51 min, with even larger potential drops for less powerful devices. CoinPrune is further aware of higher-level application data, i.e., it conserves otherwise pruned application data and allows nodes to obfuscate objectionable and potentially illegal blockchain content from their UTXO set and the snapshots they distribute.
Additive Effect of Ethanolic Extract of Black Pepper (Piper Nigrum) On Gonadosomatic Weight of Testes and Testicular Histomorphometry: In Relation to Spermatogenesis in Rabbit Bucks

This study investigated the additive effect of ethanolic extract of Black Pepper (Piper nigrum) on gonadosomatic index of the testes and testicular histology as well as testicular morphometry of Rabbit bucks. A total of twenty (20) composite Rabbit bucks aged 18 – 20 weeks were used for this study in a completely Randomized design. Experimental animals were divided into 5 groups represented as A, B, C, D, and E consisting of 4 bucks each and replicated four (4) times with a buck per replicate. The first group A (Control) was given pelleted feed that did not contain extract of black pepper. The second, third, fourth and fifth groups (B, C, D, E) had in their diet (pelleted feed) inclusion levels of black pepper extract at 100mg/kg feed, 150mg/kg feed, 200mg/kg feed (optimum) and 250mg/kg feed (above optimum). The treatment (test diet) was administered for 90 days. Ethanolic extract of Black pepper inclusion at optimum and above optimum showed statistical evidence of higher values for optimum and lower values for above optimum. Testicular length of Rabbits fed at optimum and above optimum showed (6.900±0.20) and (6.067±0.20), testes weight showed (4.47±0.40) and (1.63±0.40), testes volume showed (2.53±0.23) and (0.90±0.23), epididymis length showed (23.23±0.97) and (18.73±0.97), and gonadosomatic index results showed (0.1257±0.01) and (0.0483±0.01).

Pearls and Pitfalls of Forearm Nailing

Pediatric forearm fractures are one of the most common injuries that pediatric orthopaedic surgeons manage. Unstable fractures that have failed closed reduction and casting require surgical intervention in order to correct length, alignment, and rotation to optimize forearm range of motion and function. Flexible intramedullary nailing (FIN) is a powerful technique that has garnered widespread popularity and adaptation for this purpose. Surgeons must become familiar with the technical pearls and pitfalls associated with this technique in an effort to prevent complications.
