JUNGLES OF UKRAINIAN LEGISLATION ON EGG DONATION
Authors: Moskalenko Kateryna
Published: April 2023

The aim: To study the current regulation on egg donation in Ukraine as one of the most attractive destinations for reproductive tourism, establish the current loopholes in the legal framework to be addressed when amending Ukrainian legal rules.
Materials and methods: The article is based on studying international and regional legal acts, jurisprudence of European Court of Human rights, pieces of national Ukrainian legislation, law drafts submitted to Ukrainian parliament and legal doctrine. The methodology of the article includes dialectical, comparative method and the method of systematic and structural analysis.
Conclusions: Existing legal framework in Ukraine has some serious lacunas that can result in violation of rights and interests of donors and of the children. Firstly, the state does not keep the unique state register of donors. Secondly, there are no rules on compensation for egg donor. Lastly, the current Ukrainian legislation does not contain provisions ensuring protection of the child`s right to know about one`s genetic origin, and thus to obtain the identifying infor-mation about the donor. All these issues should be addressed in order to establish a fair balance between the rights and the interests of donors, recipients, the child and the society.

"Let $\mathcal P_{n}:=H^{*}((\mathbb{R}P^{\infty})^{n}) \cong \mathbb Z_2[x_{1},x_{2},\ldots,x_{n}]$ be the graded polynomial algebra over $\mathcal K,$ where $\mathcal K$ denotes the prime field of two elements. We investigate the Peterson hit problem for the polynomial algebra $\mathcal P_{n},$ viewed as a graded left module over the mod-$2$ Steenrod algebra, $\mathcal{A}.$ For $n>4,$ this problem is still unsolved, even in the case of $n=5$ with the help of computers. In this paper, we study the hit problem for the case $n=6$ in degree $d_{k}=6(2^{k} -1)+9.2^{k},$ with $k$ an arbitrary non-negative integer. By considering $\mathcal K$ as a trivial $\mathcal A$-module, then the hit problem is equivalent to the problem of finding a basis of $\mathcal K$-graded vector space $\mathcal K {\otimes}_{\mathcal{A}}\mathcal P_{n}.$ The main goal of the current paper is to explicitly determine an admissible monomial basis of the $\mathcal K$-graded vector space $\mathcal K{\otimes}_{\mathcal{A}}\mathcal P_6$ in some degrees. At the same time, the behavior of the sixth Singer algebraic transfer in degree $d_{k}=6(2^{k} -1)+9.2^{k}$ is also discussed at the end of this article. Here, the Singer algebraic transfer is a homomorphism from the homology of the mod-$2$ Steenrod algebra, $\mbox{Tor}^{\mathcal{A}}_{n, n+d}(\mathcal K, \mathcal K),$ to the subspace of $\mathcal K\otimes_{\mathcal{A}}\mathcal P_{n}$ consisting of all the $GL_n$-invariant classes of degree $d.$"
Generalized Functional Discriminating Measure For Finite Probability Distributions

Published: April 2023

"Analysts like Renyi (1961), Csiszar (1963, 1966), Bregman (1967), Burba-Rao (1982), Jain and Saraswat (2012), etc., have introduced and analyzed the different functional discriminating measures for comparing two discrete probability distributions.  But in this article, a new functional discriminating measure has been proposed that will compare finite (more than two) discrete probability distributions simultaneously. Further, some intra-relations among the measures at different values of the parameters have been discussed. Also, an interesting connection with Csiszar’s generalized functional measure has been created. Some new inequalities compared to variational discrimination and Chi-square discrimination have been discussed as well. "

In this paper exact values for the projective dimension of edge ideals associated to some star related graphs and product graphs $G\ \square\ P_2$, when $G=\ C_n,\ K_n$ and upper bounds for the projective dimension when $G=\ P_n,\ W_n$, are obtained. We have proved that $pd(C_{n+1}\ \square\ P_2)= 2\big(n-\left\lfloor \frac{n}{4}\right\rfloor\big)$, $pd(K_n\ \square\ P_2)= 2n-2$ and $pd(P_{n+1}\ \square \ P_2)\le n+3+\left\lfloor \frac{n-3}{2}\right\rfloor$, $pd(W_n\ \square\ P_2)\leq n+1+\lceil\frac{2n-1}{3}\rceil$. These values are functions of the number of vertices in the corresponding graphs.

Authors: Wahyudi Aditio , Arief Tirtana  , Lady Diana Langoy
Published: April 2023

Advertisers constantly try to use different communication channels to approach consumers more effectively and promptly and increase their products' visibility and attractiveness. Gojek, an Indonesian ride-hailing and delivery company, uses hashtags as part of its marketing strategy on social media platforms such as Twitter and Instagram. This research aimed to analyze Gojek's brand perception using the Twitter hashtag. This research uses descriptive analysis and sentiment analysis using Ekman's classification of emotional expression algorithm. This research analyzed 813 tweets containing hashtags related to Gojek, an Indonesian ride-hailing and delivery company, including #AmanBersamaGojek, #Cerdikiawan, #JalanTerus, #PastiAdaJalan, and #SebelumGojek, to understand the sentiment and emotional tone of the tweets. Using Ekman's classification method for identifying and categorizing emotional expressions, the analysis found that the tweets were predominantly positive in sentiment, with surprise and joy being the most frequently expressed emotions. However, the research also identified a range of other emotions expressed in the tweets, including fear, sadness, disgust, and anger, indicating that Twitter users may have more complex and nuanced attitudes toward Gojek and its hashtags. In conclusion, Gojek may consider conducting additional research and implementing strategies to address negative emotions and better engage with its audience on social media to improve its brand perception on Twitter.
Constitutionality and Ideology in the Electoral System: Pancasila’s Moral Interpretation on the Proportional Representation System
Authors: Muhtamar Syafruddin , Bachmid Fahri
Published: April 2023

This study aims to examine and analyze the constitutionality of the electoral system to the relevance of the philosophische grondslag and staatsfundamentalnorm of Pancasila and to investigate the constitutional ideological degree of the electoral system in Indonesia. This study uses normative legal research with a statute, historical, and comparative approaches. The collection of legal materials is carried out using a literature study technique. The collected legal material is then qualitatively analyzed to describe the problem and answer study purposes. The results show that the constitutionality of the PR system in Indonesian state governance is an effort to create an inclusive and democratic government. However, since the Reform Era and the post-amendment of the 1945 Constitution, the moral values of Pancasila are embedded in the preamble of the 1945 Constitution as philosophische grondslag and staatsfundamentalnorm, its implementation has not been realized in every subject matter. Additionally, Pancasila should be the standard measure of the ideological degree of the electoral system in Indonesia. Therefore, it is recommended that the Government and the House of Representatives prioritize implementing Pancasila’s moral values in the electoral system by amending the 1945 Constitution and Law Number 7 of 2017. Implementing Pancasila’s values must be concretely realized in each main subject regulated in the body of the 1945 Constitution and the norms of Law Number 7 of 2017. Furthermore, systematic evaluations of Indonesia’s electoral system should be carried out periodically to ensure alignment between the electoral system and Pancasila as the country’s ideological foundation. Thus, the design of the electoral system will become an ideological means for realizing national goals based on Pancasila ideology in the future.

Authors: Gyamfi Benjamin Osei , Zigah Gloria
Published: April 2023

The need to manage machine maintenance effectively has gained more importance due to the high rate of changing operational technologies, changing market demands, increased emphasis on employee safety, and new environmental legislation. To demonstrate the purpose of maintenance in the manufacturing value chain, the study sought to investigate the relationship between machine maintenance type and quality of output as well as to establish whether machine maintenance contributes to quality of output among Ghanaian manufacturing firms. Data was collected from 150 manufacturing firms in Tema and Accra Metropolis by using questionnaire and analyzed with SPSS and SmartPLS software. The findings showed significantly direct relationship between all the maintenance types, except corrective maintenance, and quality of output. Therefore, if a company minimizes breakdown maintenance, quality defects are also minimized. Hence, adopting preventive maintenance help reduce cost of repairs and unplanned stoppages in the production process.

The Value Network for Madhya Pradesh Minor Forest Produce Federation: Facing Off Product Diversification Dilemma
Authors: Pandey Dr. Sharadindu , Vadivelu Ananda
Published: April 2023

Commercial forestry sector in India is largely state owned. Madhya Pradesh is a unique state in India in the sense that two different forms of the organizations are working for timber and non-timber production in the state. It’s notable that Government of India has endorsed this model of doing commercial forestry and advised all the states in the country to adapt this model. It becomes important then to review the business model of the state’s forest resources especially the non-nationalized forest produce which is open for private sector. Unlike leading India based business entities like Patanjali, Dabur and Himalaya, the income generated through the network of the MP Minor Forest Produce (MFP) federation (which is government supported entity) is majorly distributing the profits among the collectors of the herbal produce. The thriving of this federation network is essential for the sake of livelihood, conservation and public health. These outcomes are relevant in the context of achieving the sustainable development goals. An independent consultant Mr. Darpan Kumar (pseudonym) analyses the business choices available in the industry and the state of strategic direction of the federation. The study presents the product/business diversification dilemma.
Comparison Study of the Top 5 Leading Cryptocurrencies based on General Consensus Protocol: Bitcoin, Ethereum, Tether, XRP and Bitcoin Cash
Authors: Alahmad Mohammed , Alfouderi Adel , Alonaizi Ahmad , Aldhamen Meshal
Published: April 2023

Bitcoin has had a tremendous impact on the monetary system around the globe today since its launch in 2009 by its founder, Satoshi Nakamoto. Since then, over three thousand cryptocurrencies have risen to compete with traditional fiat currencies. While many experts believe that cryptocurrencies are more comparable to assets like gold, few others believe that cryptocurrencies could replace traditional fiat currencies as a medium of payment, just as Satoshi envisioned when he published the Bitcoin protocol. As such, there exist few papers in the literature discussing the potential for Bitcoin to become a major payment currency. Nevertheless, there is a lack of research in evaluating whether Bitcoin is set to dominate the market as a payment currency, or whether another cryptocurrency would take the lead. In addition, the issue of strict regulation capping the potential of cryptocurrencies has been well-studied in the literature and, hence, this paper tries to evaluate the top five leading cryptocurrencies (based on their market cap value as of July 2020) from a different perspective. Particularly, the evaluation is based on five benchmark evaluation factors: Speed, Activity, Decentralization, Users, and Community. For this preliminary study, we assign all these benchmarks an equal weight. Our conclusion shows that Ethereum could be more suitable as a future payment currency rather than Bitcoin.

The Moral Status of the Human Embryo
Authors: Victoria Sokaliuk (Galushko)
Published: April 2023

Recognizing the importance of the state’s special protection of the prenatal stage of human development, most countries establish strict control over the research of the human embryo. One way to argue the limitations of embryo research is its moral status as a potential human being and representative of the human species. In the insufficient study of the moral status of the embryo, the article identifies approaches to its understanding and formulates its main features. The paper also examines the theoretical question that is at the heart of practical and professional ethics: by what criteria is the embryo attributed to have the moral status? The answer to this question reveals the importance of moral considerations regarding the proper handling of the embryos as well as the importance of the moral duty of others to treat an unborn child with respect. Some ways of understanding the principle of respect are examined separately.

The moral significance, value, and respect for the embryo are all prerequisites for establishing the limits of acceptable and unacceptable behaviour during the research on human embryos. This article highlights the problem of conflict of interests of the embryo as the one with moral status, with the interests of society to continue embryonic research due to the potential for usefulness for a huge number of people suffering from various diseases. Such conflict can be resolved through the establishment of ethical principles, which can be used to describe the limits of research on human embryos in the international and national guidelines for such research. Given the generality of such principles, it is also important to establish a national specialized committee on the ethics of research on human embryos.

Despite the results of the study, the article emphasizes the need for more detailed and deeper participation of representatives of legal, bioethical, embryological science, and the public in conversation.

Key words: moral significance, value, respect, moral obligations, legal status.

Authors:   Guizhou University of Traditionnal Chinese Medicine, Liu Chunyan , Chen Yujia , Rao Rui , Chai Yihui , Chen Yunzhi , Li Wen
Published: April 2023

Review question / Objective: 1 Whether metformin can reduce the incidence of asthma in patients with T2D. 2 Whether T2D patients with concurrent asthma can safely use metformin to reduce adverse outcomes. Condition being studied: Recent epidemiological studies suggest that metformin, the first-line medication used for T2D patients, may reduce the risk of asthma exacerbations. Therefore, this article aims to explore two research questions: first, whether metformin can reduce the incidence of asthma in patients with T2D, and second, whether T2D patients with concurrent asthma can safely use metformin to reduce adverse outcomes. This study may shed light on the efficacy of metformin as an adjunct therapy for asthma care in patients with co-morbid T2D.

Evaluation of Species Distribution and Antibiotic Susceptibility of Blood Culture Isolates of Patients Followed in the Intensive Care Unit Before and During the COVID-19 Pandemic: Retrospective, Single-Center Analysis
Authors: ARSLAN Kadir , ŞAHİN Ayça Sultan
Published: April 2023

Introduction: This study aims to identify the microorganism species isolated from blood cultures of patients hospitalized in the ICU of a tertiary center before and during the COVID-19 pandemic and to investigate their antibiotic susceptibility.

Material and Methods: Patients hospitalized in the ICU two years before and after the COVID-19 pandemic between March 15, 2019, and March 15, 2021, were divided into two groups, and their blood cultures were evaluated retrospectively. Isolated microorganisms and their antibiotic susceptibility were analyzed.

Results: A total of 1282 patients' blood cultures were analyzed, and demographic data were similar between groups. Blood culture growth was detected in 39.6% (n=202) of the patients in the pre-pandemic period and 41% (n=317) in the pandemic period. Gram-positive bacteria were isolated in 71.3%, gram-negative bacteria in 21.6%, and Candida spp. in 7.1% of the population. Klebsiella spp. was significantly higher, and Enterococcus spp. was significantly lower in blood cultures during the pandemic. In the COVID-19 period, although not significant, a decrease in antibiotic susceptibility was detected for Staphylococcus aureus, Klebsiella spp., E.coli, Enterobacter spp. and Pseudomonas spp. There was a statistically significant decrease in susceptibility to teicoplanin and linezolid in coagulase-negative staphylococci (CNS). During the pandemic, 57.6% (n=172) of the patients were positive for COVID-19. In COVID-19-positive patients, while Candida spp. was significantly higher, no decrease in antifungal susceptibility was detected.

Conclusion: During the pandemic, antibiotic susceptibility to gram-positive and gram-negative microorganisms decreased. Although there was a significant increase in Candida spp. rates in COVID-19-positive patients, there was no decrease in their antifungal susceptibility.
Recent Extragalactic Nova Rate Determinations and their Implications
Authors: Valle Massimo Della , Shafter Allen W. , Starrfield Sumner
Published: April 2023

Comparing the rates of novae in galaxies of differing Hubble types reveals the sensitivity of nova eruptions to the properties (age, star formation history, metallicity) of the underlying stellar population. Recent studies using the Hubble Space Telescope have suggested that earlier ground-based surveys may have underestimated extragalactic nova rates by factors of five or more. Here we discuss the implications of such high specific nova rates on nova theory in general, and on the chemical evolution of galaxies, including the Milky Way, in particular.

BACKGROUND: Recently with the evolution of interest and electronic devices, education was changed greatly to be easier, effective, and reasonable. Emergency medicine is a sensitive part of medicine which need rapid stabilization, examination, diagnosis, and even management of the participant.
AIM: In this study, we focused on emergency medicine registrars at King Saud medical city to know their preferred learning methods during extracurricular time. Furthermore, we investigated the relationship between certain demographic characteristics and preferred learning modality.
METHODS: We used validation questionnaire design and tested by UTAH University in the United States of America, it was a simple survey designed to cover all important points in short time. We distributed the survey using online tool (survey monkey).
RESULTS: Our study results found that podcasts was the most modality chosen by participants as beneficial and they expend their time more on podcasts. Age of participants was shown to be associated with use of internet and Google as leaning tool. We hope that researcher investigates this area of gab and future learning methods during emergency medicine doctors as well as other specialties of medicine.
CONCLUSION: We found that participants chose podcasts as a learning channel more than other modalities in our study of emergency medicine registrars at all levels and their extracurricular educational programs. Age was substantially correlated with less use of Google and online searches for educational purposes.
A general chemostat model with second-order Poisson jumps: asymptotic properties and application to industrial waste-water treatment
Authors: Sabbar Yassine , Palencia José Luis Diaz , Tilioua Mouhcine , Otero Abraham , Zeb Anwar , Djilali Salih
Published: April 2023

A chemostat is a laboratory device (of the bioreactor type) in which organisms (bacteria, phytoplankton) develop in a controlled manner. This paper studies the asymptotic properties of a chemostat model with generalized interference function and Poisson noise. Due to the complexity of abrupt and erratic fluctuations, we consider the effect of the second order Itô-Lévy processes. The dynamics of our perturbed system are determined by the value of the threshold parameter $ \mathfrak{C}^{\star}_0 $. If $ \mathfrak {C}^{\star}_0 $ is strictly positive, the stationarity and ergodicity properties of our model are verified (practical scenario). If $ \mathfrak {C}^{\star}_0 $ is strictly negative, the considered and modeled microorganism will disappear in an exponential manner. This research provides a comprehensive overview of the chemostat interaction under general assumptions that can be applied to various models in biology and ecology. In order to verify the reliability of our results, we probe the case of industrial waste-water treatment. It is concluded that higher order jumps possess a negative influence on the long-term behavior of microorganisms in the sense that they lead to complete extinction.

Published: April 2023

In this paper, we study an abstract system of fractional delay differential equations of order $ 1 < q < 2 $ with a hemivariational inequality in Banach spaces. To establish the existence of a solution to the abstract inequality, we employ the Rothe technique in conjunction with the surjectivity of multivalued pseudomonotone operators and features of the Clarke generalized gradient. Further, to show the existence of the fractional differential equation, we use the fractional cosine family and fixed point theorem. Finally, we include an example to elaborate the effectiveness of the findings.

Let $ \mathfrak M $ be an o-minimal expansion of a densely linearly ordered set and $ (S, +, \cdot, 0_S, 1_S) $ be a ring definable in $ \mathfrak M $. In this article, we develop two techniques for the study of characterizations of $ S $-modules definable in $ \mathfrak M $. The first technique is an algebraic technique. More precisely, we show that every $ S $-module definable in $ \mathfrak M $ is finitely generated. For the other technique, we prove that every $ S $-module definable in $ \mathfrak M $ admits a unique definable $ S $-module manifold topology. As consequences, we obtain the following: (1) if $ S $ is finite, then a module $ A $ is isomorphic to an $ S $-module definable in $ \mathfrak M $ if and only if $ A $ is finite; (2) if $ S $ is an infinite ring without zero divisors, then a module $ A $ is isomorphic to an $ S $-module definable in $ \mathfrak M $ if and only if $ A $ is a finite dimensional free module over $ S $; and (3) if $ \mathfrak M $ is an expansion of an ordered divisible abelian group and $ S $ is an infinite ring without zero divisors, then every $ S $-module definable in $ \mathfrak M $ is definably connected with respect to the unique definable $ S $-module manifold topology.
Star edge coloring of $ K_{2, t} $-free planar graphs

The star chromatic index of a graph $ G $, denoted by $ \chi{'}_{st}(G) $, is the smallest number of colors required to properly color $ E(G) $ such that every connected bicolored subgraph is a path with no more than three edges. A graph is $ K_{2, t} $-free if it contains no $ K_{2, t} $ as a subgraph. This paper proves that every $ K_{2, t} $-free planar graph $ G $ satisfies $ \chi_{st}'(G)\le 1.5\Delta +20t+20 $, which is sharp up to the constant term. In particular, our result provides a common generalization of previous results on star edge coloring of outerplanar graphs by Bezegová et al.(2016) and of $ C_4 $-free planar graphs by Wang et al.(2018), as those graphs are subclasses of $ K_{2, 3} $-free planar graphs.

P. aeruginosa is an opportunistic pathogen that is commonly found in nosocomial infections. The purpose of this study was to investigate the effects of seven antibiotics on P. aeruginosa planktonic growth, biofilm formation, and the expression of virulence factors. These antibiotics included Ciprofloxacin (CP), Amikacin (AMK), Vancomycin (VAN), Tetracycline (TET), Gentamicin (GEN), Erythromycin (Ery), and Clindamycin (CLI). Antibiotic susceptibility testing, Minimum Bactericidal Concentration (MBC), Minimum Inhibitory Concentration (MIC), growth curve, time-kill curve, biofilm inhibition and reduction assay, and RT-qPCR were used to assess the effects of these antibiotics on P. aeruginosa planktonic and biofilm. The clear zones of inhibition against P. aeruginosa for the CP, AMK, VAN, TET, GEN, Ery, and CLI were 26 mm, 20 mm, 21 mm, 22 mm, 20 mm, 25 mm and 23 mm, respectively. The MIC values for CP, AMK, VAN, TET, GEN, Ery and CLI against P. aeruginosa ranged from 0.25 to 1 µg/mL while the MBC values ranged from 1 and 0.5 to 2 µg/mL respectively. The growth, total viable counts (TVCs), bacterial adhesion and biofilm formation of P. aeruginosa were reduced after exposure to all the tested antibiotics in a dose-dependent manner. The RT-qPCR analysis showed that all the tested antibiotics share a similar overall pattern of gene expression, with a trend toward reduced expression of the virulence genes of interest (lasR, lasI, fleN, fleQ and fleR, oprB and oprC) in P. aeruginosa. The results indicate that all of the tested antibiotics possess antimicrobial and anti-biofilm activities, and that they may be multiple inhibitors and moderators of P. aeruginosa virulence via a variety of molecular targets. This deduction requires to be investigated in vivo.

Wireless Body Area Network (WBAN) is a tool that improves real-time patient health observation in hospitals, asylums, especially at home. WBAN has grown popularity in recent years due to its critical role and vast range of medical applications. Due to the sensitive nature of the patient information being transmitted through the WBAN network, security is of paramount importance. To guarantee the safe movement of data between sensor nodes and various WBAN networks, a high level of security is required in a WBAN network. This research introduces a novel technique named Integrated Grasshopper Optimization Algorithm with Artificial Neural Network (IGO-ANN) for distinguishing between trusted nodes in WBAN networks by means of a classification approach, hence strengthening the safety of such networks. Feature extraction process is done by using Linear Regression-Based Principal Component Analysis (LR-PCA). The test results demonstrated that the proposed IGO-ANN method attains the greatest performance in terms of accuracy, end to end delay and packet delivery ratio regarding trusted WBAN nodes classification than certain existing methods.

Recent years have seen widespread application of crowd counting and detection technology in areas as varied as urban preventing crime, station crowd statistics, and people flow studies. However, getting accurate placements and improving audience counting performance in dense scenes still has challenges, and it pays to devote a lot of effort to it. In this paper, crowd counting models are proposed based on the YOLOv5 algorithm, and four YOLOv5 models (YOLOv5l, YOLOv5m, YOLOv5s, YOLOv5x) were built for the purpose of comparing the models and increasing the accuracy of crowd identification as each model contains certain characteristics such as Filter sizes. Each model was trained on a human dataset (indoor and outdoor) for the purpose of comparing the results of each model and showing which model reaches higher accuracy in detecting people. Through this study and practical experiments conducted on each model, it was found that the best model is YOLOv5x, and YOLOv5l, where the accuracy of detecting humans reached more than 96%, while YOLOv5s reached more than 92%, and YOLOv5m reached the lowest accuracy, which is 91%.

Published: April 2023

Co-/multi-morbidities are prevalent in the elderly. Some noteworthy examples include the elderly with dementia, for example, elderly with Alzheimer's disease, Parkinson's disease dementia and vascular dementia diagnoses. Based on high prevalence rates, the elderly with dementia is likely to experience more than one disease. Usual co-/multi-morbidities in the elderly with dementia are epilepsy, diabetes, and cardiovascular diseases. For this reason, healthcare providers are tremendously challenged with demands for treatment and therapy plans to improve the quality of life and overall well-being of the elderly and their families. This Chapter discusses these co-/multi-morbidities and aims to inspire the translation of this knowledge into specialised services and therapy plans for the elderly.
Environment of Inclusion and Diversity Management on Perceived Diversity Climate
Authors: Deepak Stephen , Perwez Syed Khalid
Published: April 2023

Diversity at the workplace refers to the environment where individuals from different social backgrounds work together to pursue organizational goals. It is often difficult for individuals to accept members who belong to a different country, culture, religion, and other backgrounds. To manage this, organizations must encourage a climate that appreciates diversity and fosters inclusivity. Diversity climate in organizations is an indication of the extent that working individuals in organizations appreciate diversity related management policies, practices, and action plans aimed to accommodate everyone equally. Employees experience a sense of inclusion when their feelings of uniqueness and belongingness are addressed by the firm's inclusive initiatives making them contribute to the objectives of the organization. This study conceptually provides a theoretical understanding that inclusion and diversity management positively influences the perceived diversity climate which in turn motivates employees towards higher organizational performance.
